Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a self-moving material rack matching belt machine tail device. Background Art

[0002] Coal is an important energy source for the normal operation of the world's industry, and the coal industry is also an important economic pillar in some parts of my country. Coal mine-related production operations have complex geological conditions and high risk factors. Until now, many production processes, production equipment, and production links in the coal industry still need to be improved.

[0003] For example, the original belt conveyor tail material rack was moved forward by the tunnel boring machine dragging the belt conveyor tail rack forward. Since all the production materials required for tunneling are on the belt conveyor tail material rack, the resistance becomes larger due to its own heavy weight, especially in the process of going up the mountain, the tunnel boring machine is easy to break the dragging chain ring during the dragging process, which is very likely to cause safety hazards. Therefore, it is a technical problem that urgently needs to be improved in this field to achieve the follow-up extension of the belt conveyor tail during the tunneling process, reduce safety hazards, and improve efficiency. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and provide a self-moving material rack supporting belt conveyor tail device, which can more safely move the belt conveyor tail forward, shorten the forward movement time, and eliminate safety hazards.

[0005] In order to realize the above invention, the utility model adopts the following technical solutions:

[0006] A belt tail device for a self-moving material rack includes a wheeled tail frame, a track, a sleeper, a brake, a push cylinder, an oil pump, a controller, and a remote control. The track is placed on the sleeper, the wheel body of the wheeled tail frame can be movably placed on the track, the brake can be movably placed on the track, the wheeled tail frame and the brake are connected through a retractable push cylinder, the brake includes a brake cylinder, a pair of wedge-shaped blocks, and a block track. Under the telescopic action of the brake cylinder, the wedge-shaped block slides on the block track and clamps or releases the track. The push cylinder and the brake cylinder are both connected to the controller.

[0007] Preferably, the direction of the block track where the wedge-shaped block is located forms an acute angle with the extension and retraction direction of the brake cylinder.

[0008] Preferably, the brake is provided with a brake frame, and the block track is placed on the brake frame.

[0009] Furthermore, a clamping plate is detachably provided on the brake frame, and a clamping block track is provided on the clamping plate.

[0010] The block track can be a convex edge of the card plate, which cooperates with the groove of the wedge-shaped card block to form a relatively slidable track system. The groove can be set on the card plate and the strip-shaped convex edge can be set on the wedge-shaped card block to form a track system, or the block track can be directly set on the brake frame without the card plate. The track system is a well-known technology in this field and will not be described in detail here.

[0011] Preferably, the cylinder body of the brake oil cylinder is mounted on a brake frame, and the brake piston of the brake oil cylinder is connected to a wedge-shaped block.

[0012] Furthermore, the cylinder body of the brake oil cylinder is installed at a frame slot of the brake frame.

[0013] Preferably, the number of the wedge-shaped blocks is four, which are distributed in two pairs. The two pairs of wedge-shaped blocks are distributed at the head and tail ends of the brake. The brake cylinder is provided with a brake piston that can be telescopic in both directions, which is respectively connected to the wedge-shaped blocks at the head and tail ends.

[0014] The push oil cylinder and the brake oil cylinder are both connected to the remote controller.

[0015] The push cylinder and the brake cylinder can be manually controlled by a controller or remotely controlled by a remote controller. The automatic control of the push cylinder and the brake cylinder belongs to the known technology in the art and will not be described in detail here.

[0016] After adopting the above technical solution, the device has the following advantages:

[0017] First, improve efficiency and reduce danger. It changes the traditional method of using the tunnel boring machine to drag the tail of the belt conveyor and the material rack to move forward, reduces the hidden danger of the connecting chain breaking, shortens the time of extending the belt conveyor, and improves work efficiency.

[0018] Second, it reduces the labor intensity of workers. The material rack is moved forward by the tunnel boring machine dragging the tail frame of the belt conveyor forward. If the materials used for production are placed on the tail frame and moved forward randomly, the tunnel boring machine cannot pull the tail frame due to the weight of the materials and the weight of the tail frame itself. The production materials used can only be placed on the side of the tunnel first, and then the materials are placed on the tail frame of the belt conveyor again after the tunnel boring machine drags the tail frame forward a sufficient number of meters. This invisibly increases the labor intensity of the workers. The self-moving material rack is used with the tail frame of the belt conveyor, which is pushed forward by the push cylinder, reducing the labor intensity of the workers and also reducing safety risks.
