[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 4 As shown, an embodiment of the present invention provides a self-propelled belt conveyor extension auxiliary device, comprising: a traction part, which is arranged on the electrical platform 20 of the self-propelled belt conveyor, and the traction part includes a lifting wire rope 4; a support part, the lower end of which is fixed to the tail longitudinal beam 18 of the self-propelled belt conveyor, and the support part is inclined relative to the vertical direction; a lifting part, which is arranged to be raised and lowered, and the lifting wire rope 4 crosses the support part and is connected to the lifting part, and the lifting wire rope 4 drives the lifting part to rise and fall, and the lifting part is used to lift the loose belt of the self-propelled belt conveyor. The belt is composed of an upper belt 1 and a lower belt 2.

[0026] In this embodiment, the traction part arranged on the electrical platform 20 includes a lifting wire rope 4, which crosses the support part and is connected to the lifting part, and can also drive the lifting part to rise and fall, and can adjust the height and position of the loose upper belt 1 and lower belt 2 of the self-moving belt conveyor, and can avoid hitting the staff while lifting the loose upper belt 1 and lower belt 2, thereby avoiding the occurrence of safety accidents. The support part inclined relative to the vertical direction can adapt to terrains with different slopes, provide stable support, reduce the swing or potential safety risks of the loose upper belt 1 and lower belt 2 during the lifting process, and increase the applicability of the equipment. The existence of the electrical platform 20 can realize automatic operation of the entire process, reduce the time wasted due to manual adjustment, and can also reduce failures caused by human operating errors, thereby improving the reliability of the entire device. Through the joint action of the traction part, the lifting part and the supporting part, the loose upper belt 1 and the lower belt 2 of the self-moving belt conveyor can be easily lifted. The staff can arrange the supporting components on the ground without worrying about hitting the belt conveyor or the loose upper belt 1 and the lower belt 2, thus avoiding safety accidents. In addition, the use of this device can also simplify the process of laying the supporting components, reduce manual operations, reduce labor intensity, and improve the efficiency of the belt conveyor extending deep into the excavation working face.

[0027] Specifically, when the tail 27 of the self-moving belt conveyor needs to move deep into the excavation working face, the tail longitudinal beam 18 and the electrical platform 20 are extended toward the excavation working face on the slide rail 21 through the self-moving jack 28 and the lifting jack 22 on the tail 27 to ensure that the length of the belt conveyor can meet the requirements of coal transportation and slag discharge. The self-moving jack 28 and the lifting jack 22 both have pulleys to facilitate movement on the slide rail 21. The support assembly is a combination of an H frame 23, a support beam 24, a roller frame 25, and a roller 26.

[0028] like Figure 1 As shown, the traction unit further includes a winch 3 , which is disposed on the electrical platform 20 , and is used for winding and unwinding a lifting wire rope 4 .

[0029] In this embodiment, by winding and unwinding the wire rope by the winch 3, the risk of direct contact between the staff and the lifting wire rope 4 can be reduced, the labor intensity can be reduced, the accidents caused by improper human operation can be reduced, and the safety accidents during the operation can be reduced. In conjunction with the electrical platform 20, the lifting and release of the lifting wire rope 4 can be accurately controlled, the lifting and release time can be shortened, the wear of the lifting wire rope 4 can be reduced, the service life of the lifting wire rope 4 can be extended, and the operation efficiency can be improved. The tension and length of the lifting wire rope 4 can also be adjusted according to different operation requirements to ensure that the tension of the lifting wire rope 4 is uniform, reduce the damage of the upper belt 1 and the lower belt 2 during the lifting process, and can adapt to different lifting weights and operating environments.

[0030] Specifically, the support part includes two parallel support frames 13 and a support rod 14 located between the two support frames 13. The lower end of the support frame 13 is fixed on the tail longitudinal beam 18. The support frame 13 is inclined relative to the vertical direction. The two ends of the support rod 14 are respectively fixedly connected to the upper ends of the two support frames 13. The support rod 14 supports the lifting wire rope 4.

[0031] In this embodiment, the support part includes two support frames 13 arranged in parallel, and are respectively fixedly connected to the two ends of the support rod 14, so that the load can be evenly distributed to the two support frames 13, reducing the burden of a single support frame 13, improving the bearing capacity of the overall structure, and being able to support the lifting part to lift the loose upper belt 1 and lower belt 2 of the self-moving belt conveyor. The support rod 14 directly supports the lifting wire rope 4, reducing the wear and damage caused by the contact between the lifting wire rope 4 and other hard objects. The support frame 13 is tilted relative to the vertical direction, which can adapt to uneven ground, providing a stable inclined support surface, ensuring that stable support can be provided regardless of the terrain conditions, helping to maintain the stability of the lifting wire rope 4, and reducing the instability caused by the swing of the wire rope. Moreover, the lower end of the support frame 13 is fixed to the tail longitudinal beam 18 by fixing bolts, providing stable support for the entire device, easy installation, and the tilt angle can be adjusted as needed to adapt to different working environments.

[0032] Among them, a fixed pulley 6 is arranged on the support rod 14, and the lifting wire rope 4 cooperates with the fixed pulley 6.

[0033] In this embodiment, a fixed pulley 6 is provided on the support rod 14, and the lifting wire rope 4 is used in conjunction with the fixed pulley 6. The fixed pulley 6 can change the direction of the force of the lifting wire rope 4, so that it can vertically or obliquely transmit the force to the upper belt 1 and the lower belt 2 that need to be lifted, reduce the swing of the lifting wire rope 4, achieve a more stable lifting process, and reduce the potential safety risks caused by the swing. In addition, the use of the fixed pulley 6 can reduce the friction between the lifting wire rope 4 and the support rod 14, thereby extending the service life of the lifting wire rope 4 and reducing wear during operation.

[0034] like Figure 2 As shown, the support part also includes two pulling wire ropes 16, each pulling wire rope 16 cooperates with a support frame 13; one end of the pulling wire rope 16 is connected to the support leg 17 between the tail longitudinal beam 18 and the electrical platform 20, and the other end of the pulling wire rope 16 is connected to the connecting ring 15 at the upper end of the support frame 13.

[0035] In this embodiment, the support part is also provided with two pulling steel wires 16, one end of each pulling steel wire 16 is connected to the connecting ring 15 at the upper end of a support frame 13 for use in conjunction with each other, and the other end is connected to the support leg 17 between the tail longitudinal beam 18 and the electrical platform 20. The pulling steel wire 16 can provide additional stability and support force. When the device is not working or the next action is not performed, the pulling steel wire 16 can play a fixing role, fixing the device, reducing the dependence on the ground fixing point, so that the device can be used under more types of ground conditions. In addition, the pulling steel wire 16 allows the support frame 13 to be adjusted and positioned within a certain range to adapt to different working environments and requirements.

[0036] like Figure 2 As shown, the lifting part includes a lifting frame 9, a lifting wire rope 4 is connected to the lifting frame 9, and the lifting frame 9 is used to support the belt of the self-propelled belt conveyor.

[0037] In this embodiment, the lifting frame 9 is connected to the lifting wire rope 4 to support the upper belt 1 and the lower belt 2 of the self-propelled belt conveyor. The staff can easily lift or lower the upper belt 1 and the lower belt 2 by controlling the lifting wire rope 4, which simplifies the operation process, the time and labor intensity required. The lifting frame 9 can concentrate the weight of the upper belt 1 and the lower belt 2 on several supporting points, which can effectively disperse the load and improve the stability of the entire device. In addition, the lifting frame 9 provides a stable supporting structure, which reduces the risk of the upper belt 1 and the lower belt 2 swinging or sliding during the lifting process, thereby improving the safety of the operation. And using the lifting frame 9 to support the belt can reduce the direct contact between the upper belt 1 and the lower belt 2 and the hard surface, avoid damage caused by friction, and extend the service life of the belt. The lifting frame 9 can also be adjusted according to the length of the upper belt 1 and the lower belt 2, which is suitable for lifting operations of upper belts 1 and lower belts 2 of different lengths, increasing the applicability of the device.

[0038] like Figure 4 As shown, the lifting part also includes a steel pipe 11, and the steel pipe 11 and the lifting frame 9 are detachably connected. The lifting frame 9 supports the belt of the self-moving belt conveyor through the steel pipe 11.

[0039] In this embodiment, the lifting part is also provided with a steel pipe 11 detachably connected to the lifting frame 9, and the lifting frame 9 supports the upper belt 1 and the lower belt 2 through the steel pipe 11. The detachable connection design makes the installation and removal of the steel pipe 11 and the lifting frame 9 easier and faster, which helps to improve the efficiency of maintenance and replacement. The length of the steel pipe 11 can be adjusted, and can be adjusted according to different widths of the upper belt 1 and the lower belt 2, which improves the versatility of the device.

[0040] Optionally, the surface of the steel pipe 11 in contact with the upper belt 1 and the lower belt 2 is a smooth curved surface, which can reduce the direct contact between the upper belt 1 and the lower belt 2 and the hard surface, avoid damage caused by friction, and extend the service life of the upper belt 1 and the lower belt 2.

[0041] like Figure 4 As shown, the lifting frame 9 has a plurality of groups of hooks 12 distributed in the height direction, each group of hooks 12 includes two hooks 12 arranged opposite to each other, and the two ends of the steel pipe 11 are hung on the two opposite hooks 12 respectively.

[0042] In this embodiment, the lifting frame 9 is further provided with a plurality of groups of hooks 12 in the height direction, so that the steel pipe 11 can be fixed at a plurality of different heights, which is convenient for adjusting the position of the steel pipe 11 according to the height or operation requirements, thereby increasing the applicability of the lifting frame 9. Moreover, each group of hooks 12 includes two hooks 12 arranged opposite to each other, which can provide a more stable support point and reduce the instability or tilting caused by single-point support. Hanging the two ends of the steel pipe 11 on two opposite hooks 12 respectively can fix the steel pipe 11, and can better lift the upper belt 1 and the lower belt 2, thereby preventing the upper belt 1 and the lower belt 2 from falling due to the falling of the steel pipe 11, thereby preventing unnecessary safety accidents. The provision of multiple groups of hooks 12 can also increase the structural strength of the lifting frame 9, enabling it to withstand a larger load.

[0043] like Figure 3 As shown, the lifting frame 9 includes two vertical plates arranged in parallel and a connecting rod 10 arranged between the two vertical plates, and the lifting wire rope 4 is connected to the connecting rod 10.

[0044] In this embodiment, the lifting frame 9 is further provided with two parallel vertical plates and a connecting rod 10 arranged between the two vertical plates, and the lifting wire rope 4 is connected to the connecting rod 10. The structure formed by the two parallel vertical plates and the connecting rod 10 is similar to a door frame structure, which is symmetrical and can withstand large vertical and horizontal loads. The connecting rod 10 between the two vertical plates can make the force applied by the lifting wire rope 4 on the lifting part more uniform, reduce the pressure on a single connection point, and reduce the risk of deformation or damage of the lifting frame 9 due to load concentration.

[0045] like Figure 4 As shown, the connecting rod 10 is provided with a lifting ear 8 which is detachably connected to the lifting wire rope 4 via a butterfly buckle 7 .

[0046] In this embodiment, a lifting lug 8 is provided on the connecting rod 10, and the lifting lug 8 is detachably connected to the lifting wire rope 4 through a butterfly buckle 7. The lifting wire rope 4 drawn from the winch 3 passes through the guardrail 5, bypasses the fixed pulley 6, and is connected to the lifting frame 9 through the butterfly buckle 7 and the lifting lug 8. The guardrail 5 can prevent the lifting wire rope 4 from being quickly recovered due to unstable connection and causing safety accidents. The use of the butterfly buckle 7 allows the connection between the lifting lug 8 and the lifting wire rope 4 to be quickly disassembled, which is convenient for installation and maintenance. Moreover, the combined use of the lifting lug 8 and the butterfly buckle 7 can reduce the impact and vibration caused by the hard connection, thereby improving the durability of the system.

[0047] The self-propelled belt conveyor extension auxiliary device in the present application can flexibly adjust the height of the upper belt 1 and the lower belt 2 by lifting the lifting part, ensuring that the upper belt 1 and the lower belt 2 will not interfere with the staff when setting the support assembly. The setting of the winch 3 makes the winding and unwinding of the lifting wire rope 4 more convenient, and improves the efficiency of the operation. The design of the support part not only stabilizes the entire device, but also helps the smooth lifting of the upper belt 1 and the lower belt 2 through its tilting setting. In addition, the detachable and adjustable design of the device makes it more adaptable in different working environments and more convenient to operate, which improves the working efficiency and safety of the belt conveyor in complex environments such as coal mines. The portability and quick installation design of the device can reduce the time required for equipment adjustment and improve efficiency. At the same time, it reduces manual intervention, reduces the work intensity and safety risks of operators, and improves the safety and continuity of coal mining.
