Complex for sinking mines

 

(57) Abstract:

The invention relates to equipment for the coal mining industry and construction, in particular for carrying out horizontal and inclined workings. The invention is directed to improving the efficiency of the functional equipment of the complex. The complex includes a support frame gantry undercarriage trucks, drilling equipment, loading equipment, consisting of ladles side discharge on the handles attached to the shafts with longitudinal movement of the boom actuators loading bodies placed in the side walls of the portal frame inside the support beams running trucks. 3 Il.

The invention relates to equipment for the coal and mining and tunnelling, in particular for carrying out horizontal and inclined workings.

Known unit for tunneling along.with. N 296850, including chassis frame (portal) shelves, grapple for loading of the rock drilling machine.

The disadvantage of this Assembly is that the loader bucket type has a low performance and does not allow to sweep the ground, and the front uprights of the portal preneu is the unit for sinking mines along. C. N 16661429 M CL S E 21 D 9/10 (publ. 07.07.91. Bull. 25), comprising a movable support frame (portal), which established mechanisms for drilling of boreholes, construction of supports and loading of the rock mass.

The disadvantage of this Assembly is that the focus is almost in the same place (space) unit two units of multifunctional equipment greatly complicates the control system and its maintenance.

The presence of one of the bucket body capacity (as can be seen from figure) not exceeding 0.15 m3indicates low productivity of loading rock mass.

The aim of the invention is to simplify the control system and the efficiency of loading machines. This objective is achieved in that complex that includes a support frame gantry undercarriage trucks, drilling equipment, loading equipment, consisting of ladles side discharge on the handles attached to the shafts with longitudinal movement, characterized in that the boom is placed in the side walls of the portal frame inside the support beams running trucks that serve as their guides.

Comparative and Zmeiny in the side walls of the portal frame inside the support beams running trucks. Thus, the claimed technical solution meets the criterion of "novelty."

Analysis of the known technical solutions (analogues) in the study area leads to the conclusion about the absence of these characteristics with significant distinguishing features of the proposed tunnel system and to recognize the claimed solution meets the criterion of "significant differences".

The invention is illustrated by drawings, where Fig. 1 is a side view of the described complex in the transport position of Fig. 2 is a top view in the process of loading rock mass, Fig. 3 - side view.

The complex of Fig. 1, 2, 3 contains a frame gantry (portal), consisting of side walls 1 with support beams 2 at sea 3 trucks moving along the track 4, the upper connecting frame 5, the drilling rig 6 moving along the guides 7, mounted on frame 5. In the supporting beams 2 are embedded arrows 8, which move in the guide roller nodes 9, mounted on a support beam 2 by means of hydraulic cylinders 10. On the front ends of the shafts pivoted arms 11 with buckets 12 a side discharge. Supporting beams 2 is equipped with brakes 13, preventing rollback of the complex in the introduction to equipped with hydraulic actuators, and when conducting slant mining complex moves using the winch and rope, and systems snatch blocks 14. The loading machine and the drilling rig is equipped with control panels and seats 15, 16.

The complex operates as follows. Tunneling cycle begins with the drilling of boreholes, for this drilling device 6 is moved along the guides 7 in the extreme forward position of the upper frame 5, which allows to overwhelm the entire area of the face. After abrevaya downhole drilling device is returned to its rearmost position, and the complex Argonauts the necessary distance.

After blasting and ventilation proceed to the loading of the rock mass (Fig. 2). Initially, the bucket 12 in the middle part production using manipulators 11 produce sweep the track by movement of the entire complex on the carrier trolleys 3.

Loading of the rock mass in the skip or the cart are two buckets at the same time in the following sequence. First is the introduction of buckets in a pile and scoop breed by extension shafts 8 moving in the guide roller nodes 9 with the help of hydraulic cylinders 10, is placed inside the supporting beams 2. After the intelligence is, 2.

Loading of the rock mass is one of installation on the length of the boom loading body, which is equal to the length of the vehicle (trolley, skip) and 2.3 - 5 m, after which the complex is shifted by the distance to the complete Stripping of the face.

After unloading rocks produce the erection of the lining, using buckets as a regiment, and drilling machines with removable appliances for installation of the lining elements.

The proposed solution allows to significantly improve the efficiency of their functional equipment of the complex by simplifying the system control machine (cultures of the consoles in different points of the complex), to improve maintainability and safety, a 5 - to 6-fold increase in the productivity of loading equipment.

Venue for mining, including support frame gantry undercarriage trucks, drilling equipment, loading equipment, consisting of ladles side discharge on the handles attached to the shafts with longitudinal movement, characterized in that, in order to increase the effectiveness of functional Obote support beams running trucks.
