The invention concerns a tool for disassembly of the cutter in the holder with the Executive management, which has the release site, and the actuating element is movable along the direction of movement.

Such an instrument is known from WO 97/23710. When this is executed in the form of a trunnion release section is attached to the handle by a swivel. The tools used for disassembly of the tool, which is inserted into the receiving bore of the tool holder. The receiving hole is made as a through hole so that the shank of the inserted cutter is available from the rear. At the end of the shank cutter mounted locking element, which is disposed in the groove of the inlet opening and thus holds the cutter in the holder. If the cutter, for example, upon reaching its limit of wear should be replaced, the release of land through located on the rear side of the hole is pushed into the receiving hole and is in contact with the free end of the rod cutter.

The handle can then be rotated up until it will not come into contact with the supporting section. Now can the handle be opposite of squeezing plot in a swivel. The resulting lever force is transmitted through the release of land in the cutter so that caused the blocking element removes a jammed the I. When the cutter is removed and the tool is removed, the new, Neizvestny cutter can be inserted into the receiving hole and hammer the hammer. Performing replacement cutter well-known scheme is associated with high costs of efforts and limited space is not safe.

From DE 3026930 A1 a device for dismantling. He needed a plunger which is mounted in the region of the inlet opening for the cutting tool. The plunger can be moved linearly to the shank of the rod cutter so that may be ejected from the inlet opening to the outside. For the drive of the pusher applied by a hydraulic system or a mechanical lever system. These known tools require a large design space, which may not always be available. Moreover, during the operation of the minute particles of the developing material fall into the receiving hole made in the form of a blind hole, and there may not be removed. They then have a negative impact on the functioning of the device for dismantling and free rotation of the cutter during the operation.

Another known tool that offers Assembly or disassembly of the cutter in his head. For example, DE 4323669 C1, DE 8403441 U1, US 6526641 B1 and DE 3223761 C1 show gripping puller. He moved clamps included in the circular groove of the cutter head. Then the grippers can be moved to dismantle the longitudinal direction of the cutter. These known tools require constantly shaped surface on the cutter head, which they can capture behind when removing the cutter. If due to strong wear this cutter shaped surface worked or the pick head is destroyed, the tool is ineffective.

The objective of the invention is to create a tool mentioned at the beginning of the form, which will greatly simplify the replacement of the cutter.

This task is solved in that the actuating element is arranged to bias through the mounting block and mounting block has an engaging portion which is at a distance from the squeezing area and is located across the direction of movement of the adjusting block, and the actuating element is configured to power the bring in the direction of movement through the installation of the unit in two directions.

While the release site is used for Dismounting the cutter, in the mounting position of the cutter may be driven retractor plot. This is possible by using a distribution block, which moves the actuating link in two directions and thereby in the direction of installation or removal. Executive link is configured to power the drive via the adjustment unit, for example, through electrical or hydraulic drive, Thu is the replacement cutter for the user is greatly facilitated. Thus, the tool according to the invention can carry out the installation and dismantling.

According to one possible variant of the invention can be provided that the Executive link between the pressing section and the sucking section is available across a direction of travel of the Executive managers of the receiving area. The cutter can easily be inserted into the receiving area adjusted by the contour of the housing. For example, the contour of the housing may have a circular groove in the shank of the cutter, which includes Executive level.

If it is provided that the length of the receiving section across the direction of feed is less than or equal to the maximum cross section Executive level in this area, the receiving area does not exceed Executive level across the direction of feed. Due to this compact design is achieved. This is, for example, then has advantages when the cutter should be mounted and removed through the suction hole that holds the cutter.

In order to achieve a simple way centered orientation of the cutter on the tool may be provided that the actuating element with the pressing section and the sucking section is made in the form of capture, and that the arcuate or, in particular, in the form of a circle insertion groove is limited to the pressing part is kOhm and engaging plot. The cutter can be inserted in the insertion groove, for example, a cylindrical belt.

In order to create a high mounting and, in particular, also demolition efforts, one variant of the invention provides that the installation unit has a hydraulic unit with a hydraulic cylinder, which can move installed the piston and the actuating element via the piston rod is connected with the piston. Thus, the hydraulic unit can have a reversible block, which allows bidirectional power loading of the piston.

To provide a simple, easy-to-use tool, one variant of the invention provides that the hydraulic unit is attached to the motor, which is connected to the battery, and that the hydraulic unit, the motor and battery are combined in one manually driven constructive unit. In this case, the tool can be actuated independently from the external power supply and therefore easy to manipulate them.

Assembly and disassembly can be performed properly if between the cutter and the Executive level to make positive locking. For this purpose according to the invention can be provided that the installation unit has two facing in opposite directions, the supporting surface that the PR is interevene in the direction of movement of the actuating element.

To get as during installation and dismantling robust connection mounting tool may be provided that the installation unit has two basic parts, which are located at a distance relative to each other in the direction of movement. These basic parts of the instrument can rely on specially provided for this purpose, the mating surfaces of the tool holder, etc.

The tool unit comprises a base 20, which is installed with the concave bearing surface 24 and is welded to the surface 11 of the drum. The base 20 has a receiving element 21 to the tool, in which you inserted the cutter 30, in particular, with a round shank. The cutter 30 is usually the pick head and attached thereto, the shank 33 of the cutter. The cutter 30 in the area of the shaft 33 carries the clamping sleeve 35, as shown in figure 3. The clamping sleeve 35 is included with the retainer 36 in the circular groove 34 of the shank 33. The sleeve can rotate freely, but is held without the possibility of falling in the axial direction.

In an embodiment of the tool according to figure 3-5 in the mounting position of the head of the cutter rests on the supporting surface of the holder 40 through located between protecting them from wear washer 31. At its facing away from the cutter head end of the shank 33 has a terminal element, which does not overlap the clamping sleeve 35. This end element of the will is formed band 37, the diameter of which is smaller than the diameter of the remaining area of the shank. The belt 37 is equipped with a circular groove 38. The groove 38 is adjacent the cylindrical support part 39.

The holder 40 has as centering receiving element 41 passing around receiving element 42 of the cutter chamfer, which limits the introductory hole 43 for the cutter 30. Tool holder 40 can be inserted into the receiving element 23 of the holder base 20 and rigidly connected with the base 20, for example, welded (see weld seams 46 figure 4). In case of wear welds 46 are separated and the tool holder 40 is replaced with a new Neizvestny. For example, a variant of execution of the instrument, in which the base 20 and the holder 40 are United in one piece in the form of a module (see figure 1).

As further can be seen in figure 3 and 4, the base 20 and the tool holder 40 form a pocket-type hollows. provinces form the recess 45 according to figure 1, open on the sides and on the top side.

In this recess 45 can be inserted tool. You can paste for Assembly and disassembly of the cutter 30.

The tool has a mounting block 60, which surrounds the cylindrical inner space 63. In the inner chamber 63 between the two extreme positions linearly moves the piston 66. The piston 66 is sealed by an annular seal relative to the cylindrical wall bounding in the morning the camera. The piston 66 is attached the piston rod 67, which is derived from the internal chamber 63 through the locking insert 68. Locking insert 68 is hermetically inserted into the open side of the mounting block 60. The piston rod 67 is also sealed relative to the locking insert 68, so it's a sealed inner chamber 63. The piston rod 67 carries at its free pointing away from the piston 66 the end of the actuating link 70. The actuating link 70 is fixed clamping pin 72 inserted into the hole 71 Executive level 70. The actuating link 70 has an engaging section 73 and the release section 74. They are located at a distance relative to each other so that the formed grip. The distance is selected so that the cutter 30 can be inserted into the grip so that the engaging section 73 is included in the groove 38.

Mounting block 60 has at its rear end supporting part 61, which formed the advanced path.
