Description

Technical Field

[0001] The present invention relates to the technical field of coal mining, in particular to a mining open-end transfer machine. Background Art

[0002] During current coal mine excavation, the roadheader (TBM) directs the excavated material onto a belt conveyor, which then transports it to a designated location in the tunnel. The existing tunneling conveyor belt is only approximately 10 meters long, carrying this length on the conveyor. If the TBM moves beyond this length, the tail of the belt conveyor must be moved. At the current TBM's excavation speed, the conveyor must be moved daily. This tunneling and transportation arrangement presents several problems: Because the belt conveyor itself is bulky, specialized personnel are required to extend it, and this time-consuming process necessitates that the TBM be stopped until the extension is complete. This is especially true for tunnels with horizontal bends, where ensuring the belt extends properly at the bend is labor-intensive and time-consuming, significantly impacting tunneling efficiency, increasing personnel safety risks, and raising operating costs for the enterprise. Furthermore, during machine movement, cables can become tangled and fall to the ground, impacting the machine's operation. Summary of the Invention

The crawler frame comprises a crawler chassis and a crawler frame, wherein the crawler chassis has a crawler frame, and the crawler frame has a plurality of supporting wheels. The crawler frame has a plurality of supporting wheels at the bottom sides of the crawler frame, and a driving sprocket and a driven sprocket are installed on the middle two ends of the crawler chassis. The driving sprocket and the driven sprocket are connected by a chain transmission. A plurality of chain plates are installed on the outer side of the chain, and a bending protrusion structure is provided on the chain plate, and the bending protrusion structure includes a protrusion with a curvature perpendicular to the conveying direction of the chain plate, and the rear of each chain plate has an angle change. A connected material bin and a discharge bin are installed on the crawler chassis, and a bin door is movably installed on the discharge bin.

[0014] Preferably, the winding mechanism includes a bracket, a roller seat is installed on the bracket, and the roller seat is rotatably connected to the roller shaft of the cable winding drum, a first sprocket is installed on the roller shaft, a wheel frame is installed on the bracket, two transversely arranged guide wheels are installed on the wheel frame in parallel, both ends of the two transversely arranged guide wheels are installed with shaft seats, two vertically arranged guide wheels are installed between the two shaft seats located at the same end of the transversely arranged guide wheels, a servo motor is installed on the bracket, a second sprocket is installed on the output end of the servo motor, and the second sprocket is connected to the first sprocket through a chain transmission;

[0015] The servo motor and the first drive motor are controlled by a controller to work synchronously.

[0016] Preferably, the specific operating steps of the mining open transfer machine are as follows:

[0017] The first drive motor drives the driving wheel to rotate, and then drives the crawler to transmit on the driving wheel, the driven wheel and the supporting wheel. When the first drive motor on the two crawler frames drives the driving wheels to rotate at the same speed, the machine can move forward and backward.

The tunnel boring machine transports the excavated materials into the silo, and the machine moves to the unloading position. At this time, the pneumatic cylinder is extended to drive the silo door to flip and open the discharge silo.

The servo motor drives the first sprocket to rotate, and the chain drive drives the second sprocket and the cable drum to rotate to achieve cable winding and unwinding. The cable passes between the two guide wheels, and the guide wheels serve as guide limits.

[0019] The beneficial effect of the present invention is that after using this machine, continuous excavation operation can be realized. Especially when the excavation tunnel is up and down slope, the excavation material is small, and the transportation range of the belt conveyor is exceeded, the mobile belt conveyor can be replaced to realize temporary transfer of materials, thereby ensuring the continuity of the excavation work and making effective contributions to mine safety production, quality improvement and efficiency enhancement.

[0020] The front part can be arbitrarily matched with various types of tunnel boring machines or excavation loading machinery, and the rear part can be used in conjunction with a belt conveyor to realize intermediate transfer and continuous mining, contributing to mine safety production, quality improvement and efficiency enhancement. This product can realize functions such as large-tonnage loading, uphill and downhill turning transfer, intelligent follow-up, and remote control. It meets the needs of enterprises for the development of new quality productivity, continuity of tunneling work, and mine safety production, reduces personnel input, improves work efficiency, and has high safety performance, flexibility and reliability.

[0021] By adjusting the height of the machine through the lifting cylinder, the height of the transfer and splicing belt conveyor can be freely adjusted. The winding mechanism can automatically retract and release the cable, reducing the labor intensity of workers. BRIEF DESCRIPTION OF THE DRAWINGS
