Vyveshivayuschee device with a support stand

 

(57) Abstract:

The invention relates to maintenance of vehicles, in particular for the design of hoisting-and-transport and diagnostic devices for maintenance and repair of wheeled vehicles. Designed for hanging the front axles mostly trucks and wheeled tractors, except for cars with wheel formula 3 x 2, as well as to alternately display the front and rear axles of the models of cars with the wheel formula 4 x 4. Can be used for maintenance and repair of these machines both stationary and field conditions. The device is equipped with a support stand And is shaped with a pair of front and a pair of rear legs, whereby there is the possibility of interaction of the beam front or rear axle of a moving vehicle with nozzles in the form of lugs, which are placed on the arms, which is a continuation upward of the rear legs of the stand. As a result, the hanging bridge (or bridges alternately - for machines with wheel formula 4 x 4) is on the stand under the action of the driving forces of inertia and gravity service machines. The device is energy efficient and metabromine refers to the maintenance of machines, in particular, to the design of hoisting-and-transport and diagnostic devices for maintenance and repair of wheeled vehicles. Designed for hanging the front axles mostly trucks and wheeled tractors, except for cars with wheel formula 3 x 2, as well as to alternately display the front and rear axles of the models of cars with the wheel formula 4 x 4. Can be used for maintenance and repair of these machines both in the hospital and in the field.

Lifting devices are widely used for maintenance of trucks, tractors and other vehicles. With these devices the machine is hung in whole or in part on the frame or on the bridges in a comfortable position to perform repair and maintenance work. Known Electromechanical, hydraulic and mechanical lifting devices/1, 2, 3, 4, 5/.

The disadvantage of these devices is that they are complex. In addition, the lifts /1, 2, 3, 4/ are driven from the power plant.

The closest technical solution, selected as a prototype, is the lift for marking vehicles, consisting of sanavlvarian its own power to the unit for service /6/.

A disadvantage of the known construction is that it contains a swinging frame, a movable carriage, a hydraulic pump with a mechanical drive and hydraulic system hydraulic units. In this regard, the design of the lift complex, bulky and expensive, and the use of energy driving the vehicle is ineffective.

The objective of the invention is to simplify the design of the lifting device and the efficiency of energy driving the vehicle while it is hanging.

The invention consists in the following. The stand is made And shaped with a pair of front and a pair of rear legs, the latter of which she pinned on the ground. This stand is equipped with levers, which is a continuation upward of the rear legs. On the levers placed nozzles for interaction with the beam axle of the vehicle. Backup rigidly connected to the base and placed with the opportunity to interact with one of the rear legs when the stand deviation in the direction opposite to the movement of the vehicle when submitting it to the service. This provides the possibility of putting the machine in its movement by the interaction of the x means with different height of beam bridges backup has the ability longitudinal movement on the support surface of the base along the axis of symmetry of the treadmill. In addition, on a treadmill made two hollows under the wheels of post bridge. In General, it can simplify the design of the lifting device and to improve the energy efficiency of driving the vehicle in the process of putting up.

In Fig. 1, 2 shows vyveshivayuschee device with a support stand. It consists of an a-shaped support stand with nozzles 5, installed on a supporting surface of the base 1 between the lines of the treadmill 10, and backup 3. The stand consists of a pair of front 6 and rear pair 4 pins, And the United-figuratively among themselves, and by 8 longitudinal and transverse 11 jumpers. The endings of the front 6 of legs rigidly attached to the abutment 7. The end of the rear legs by hinges 2 are connected with the base 1. Back 4 legs have continued upward from the joint /hard/ connections legs as levers, which are nozzles 5 for interaction with the beam axle of the vehicle. The stand has a possibility of deviation from the vertical plane in the direction of movement of the machine when submitting it to service its course and in the direction opposite to that movement. The angle of deviation / plus / limited on the one hand, Podo the awn longitudinal movement on the support surface of the base 1 - along the symmetry axis of the treadmill 10 that allows you to adjust the installation of the nozzle 5 in height. In addition, this prop has the ability to interact with one of the back 4 legs when the stand deviation in the direction opposite to the movement of the vehicle when applying for service. When this angle may be greater than angle , but should not exceed 80 - 85o. On the treadmill 10 can be made two recesses 9: one for left and another for right wheel post bridge machine. Each recess 9 is a longitudinal cross-section the shape of an isosceles trapezoid, with an obtuse angle with the bottom base. At the hospital, the stand may be pivotally attached to the base 1 or to the cross beam rigidly installed in the base. In field conditions, the stand may be pivotally connected with the beam, rigidly installed in the ground, which can also be made of the recess 9.

The hanging of the front axle of a vehicle such as a tractor, is as follows. The machine runs its course forward on the treadmill 10 in the direction of the arrow /Fig. 1, 2/. Stand deflected from the vertical plane at some angle and is held in this position is necessary, adjust the position nasdaw 5 in height by longitudinal movement of the struts 3. Recesses 9 are made so that each width overlaps the width of the tractor wheels, installed on the treadmill. The stand is placed in the longitudinal direction relative to the recess 9 so that the wheels of the machine after the operation was over the recesses. Under the action of the driving force and the inertia of the tractor beam bridge presses the nozzle 5. Stand together with bridge swivels for 2 on the corner : the bridge is lifted. Then under the action of gravity of the machine axle is lowered, turning the stand at an angle to the contact between the front legs of a support with a support surface of the base 1. When this beam hangs on a stand, wheel bridge over the recesses 9, the axle of the tractor is posted in the state. After completing the necessary repair and maintenance work, the machine runs its course in the opposite direction. Stand together with the bridge under the action of a driving force and a gravity tractor is in original position in the reverse order. Hanging out the front of the bridge is completed. The device is again ready for operation. The hanging of the rear axle is in a similar way when driving in reverse.

The proposed device is energy efficient and it is a device equipped with a support stand, through which is provided the opportunity to interact beams front or rear axle of a moving vehicle with nozzles in the form of lugs. In the hanging bridge or bridges alternately - for machines with wheel formula 4 x 4/ is carried out on the stand under the action of the driving forces of inertia and gravity service machines.
