Technical Field

[0001] This utility model patent relates to a mining pushing device, and more particularly to a pushing device suitable for mining hydraulic supports. Background Technology

[0002] Hydraulic supports are widely used support equipment in underground mining operations such as coal and metal mines. They are mainly used to provide temporary or permanent support for the working face to ensure operational safety and improve mining efficiency. Hydraulic supports are characterized by their large size and weight, making their transportation in mine roadways extremely difficult. Therefore, how to efficiently and conveniently complete the transportation of hydraulic supports is of great significance for improving the efficiency and quality of support work.

[0003] Current product issues: Traditional hydraulic supports are typically transported using specialized flatbed carts and dedicated pushing devices. However, in coal production environments where monorail cranes are widely used, the end of the monorail crane's route is often a certain distance from the hydraulic support installation location. In such cases, pushing or pulling equipment is needed to move or pull the hydraulic support a certain distance for installation. Summary of the Invention

Detailed Implementation

[0024] The specific structure of this utility model will be further described below:

[0025] This utility model of a mining hydraulic support pushing device also includes a pushing mechanism 4, which comprises a connected flat base 6 and a push-pull base 5. The flat base 6 and the push-pull base 5 are in contact and spliced ​​together. It is used in conjunction with a monorail crane 2, the lower part of which is equipped with a suspension device.

[0026] This device is used in conjunction with a monorail locomotive. At the end of the monorail locomotive's journey, the monorail locomotive lowers the hydraulic support for transport onto this device. Then, this device is used to push and pull the hydraulic cylinder to move the hydraulic support within a short distance, thus solving the problem of short-distance movement at the end of the monorail locomotive's transport.

[0027] Specifically, two inner grooves are provided in the middle of the push-pull base. A pushing block and a pushing hydraulic cylinder are installed in these grooves. The pushing block has a rectangular cavity structure. The piston rod of the pushing hydraulic cylinder is connected to one side of the inner cavity of the pushing block, and the cylinder body is connected to the side of the inner groove closest to the flat base. The pushing hydraulic cylinder pushes the pushing block to move within the inner groove. A quick-release hole is opened on the plane of the pushing block, and a rotatable baffle is installed in the quick-release hole. The rotatable baffle is triangular, with its apex hinged to the pushing block. Of the other two corners of the rotatable baffle, the apex closest to the fixed side of the pushing hydraulic cylinder has a greater weight than the other apex.

[0028] After the hydraulic support is positioned onto the push-pull base by the monorail crane, space is created for the rotatable baffle. Due to its own weight, the heavier end of the rotatable baffle droops, while the lighter end tilts upwards. At this point, the hydraulic cylinder actuates, moving the push block. The exposed portion of the rotatable baffle on the push block applies a thrust to the hydraulic support until it is pushed away from the push-pull base. Then, due to the length of the push block, most of it is pushed out of the inner groove, and the hydraulic support is simultaneously pushed away from the push-pull base. This achieves short-distance displacement of the hydraulic support at the end position of the monorail crane.

[0029] Furthermore, connecting plates are provided on both sides of the push-pull base 5, and the cylinder body of the traction hydraulic cylinder 8 is hinged to the connecting plates of the push-pull base 5 via universal joints. If the end position of the monorail crane is on the flat base, a chain is provided to the extended end of the piston rod of the traction hydraulic cylinder 8 to connect to the hydraulic support. Then, the piston rod retracts, pulling the hydraulic support from the flat base to the push-moving base, and then the push-moving base moves the hydraulic support to a distant position. Furthermore, universal joints are provided on the connecting plates on both sides of the push-pull base 5, and the universal joints connect to the end of the cylinder body of the traction hydraulic cylinder 8.

[0030] The flat base 6 and push-pull base 5 of this device have a weight greater than that of the hydraulic support. Multiple flat bases 6 can be assembled side by side, which can increase the sliding distance of the hydraulic support and also increase its weight.

[0031] Furthermore, the cross-section of the push block is rectangular cavity-shaped, and the inclined surface is provided near the outer edge of the push-pull base 5. The inclined surface facilitates reducing the tilt angle of the hydraulic support when it is pushed from the push base to contact the ground and retracted.

[0032] Two sets of prying block holes are opened on the upper surface of the push block. The piston rod end of the push hydraulic cylinder is fixed in the middle of the inner cavity of the push block. The rotatable baffle is set in the middle of the push block and at the insertion position port of the push hydraulic cylinder. There are two rotatable baffles arranged in parallel at each location.

[0033] The tops of the flat base 6 and the push-pull base 5 are on the same plane to facilitate the pulling of the hydraulic support from the flat base onto the push-pull base. Connecting grooves are provided on the contact surfaces of the push-pull base 5 and the flat base, and connecting plates 7 are installed within these grooves to fix the push-pull base 5 and the base. When multiple flat bases are arranged side-by-side, connecting grooves and connecting plates are also provided to connect the connected push-pull bases 5 and flat bases.

[0034] Furthermore, the push-pull base 5 is divided into two parts with symmetrical and identical structures. Each part has a mating groove at its contact surface, with screw holes inside the grooves. A mating plate with two through holes is placed in the mating grooves of both parts, and bolts inserted into the through holes are screwed into the screw holes to secure the two parts of the push-pull base 5. Multiple flat bases 6 are arranged side-by-side and connected by connecting grooves and connecting plates.

[0035] The monorail crane 2 used in conjunction with this device is for transporting hydraulic supports. The monorail crane 2 comprises a track 1, multiple sets of load-bearing trolleys, a lifting beam, a rotating lifting frame, and a lifting chain. The load-bearing trolleys run on the track 1. Multiple sets of load-bearing trolleys are connected to the upper part of the lifting beam. The lower part of the lifting beam is connected to the rotating lifting frame via a rotating bearing. The lifting frame is equipped with a lifting chain, and the lower end of the lifting chain is fixed to the hydraulic support. The pushing mechanism 4 of this device includes a flat base 6 and a push-pull base 5. The tops of the flat base 6 and the push-pull base 5 are on the same plane. Connecting grooves are respectively provided on the contact surfaces of the push-pull base 5 and the base. Connecting plates 7 are installed in the connecting grooves to fix the push-pull base 5 and the base.

[0036] Before using this device, use the lifting beam of a monorail crane to transport the pushing mechanism to the designated position, lay the pushing base and flat base flat, and then install and fix the connecting plate.

[0037] The steps for using this device are as follows:

[0038] 1) Assemble and place this device on the ground, specifically by splicing multiple flat bases starting from the end of the monorail crane's running position, extending to the hydraulic support installation position, and finally installing the pushing base;

[0039] 2) After adjusting the angle, the monorail crane places the hydraulic support onto the flat base, such as... Figure 3 The right side of the status;

[0040] 3) Using a traction hydraulic cylinder to connect the hydraulic support, the traction hydraulic cylinder actuates, pulling the hydraulic support from the supporting flat base to the push-pull base. The rotatable baffle on the push-pull base, due to its hinge, can swing, pushing one corner to the bottom of the hydraulic support to the pushing side, without obstructing the traction of the hydraulic support. Figure 3 The state is on the left;

[0041] 4) Finally, the hydraulic support is fully pulled onto the push-pull base, with the rear rotatable baffle at the edge of the hydraulic support and a small corner protruding from the push-pull base.

[0042] 5) Control the moving hydraulic cylinder to move the rotatable baffle forward. The rotatable baffle pushes the hydraulic support forward, causing it to follow. Push the hydraulic support to the front of the platform, then retract the moving hydraulic cylinder. Next, use the front rotatable block to push the hydraulic support forward again, fully extending the hydraulic support out of the push-pull base and lowering it completely. Figure 4 state;

[0043] 6) Extend the pushing part forward to press against the hydraulic support, causing the pushing mechanism to move backward. Then retract the pushing part to prepare for the placement of the next hydraulic support. Figure 5 state.

[0044] This device solves the problem of short-distance displacement caused by the lack of hydraulic support installation on the monorail locomotive. This device can be used as an accessory to the monorail locomotive, facilitating easy handling and eliminating the need for additional lifting manpower or equipment.
