DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0023] like Figures 1 to 6 As shown, the present invention provides a device for preventing a traction rope from damaging a roller surface, comprising a clamp 1, a swing arm 2, a hole forming assembly 3 and a locking rod 4, wherein the clamp 1 is used for clamping and fixing on a frame of a belt conveyor, the outer end of the swing arm 2 is rotatably mounted on the clamp 1, the locking rod 4 is arranged between the swing arm 2 and the clamp 1, and is used for fixing the inner end of the swing arm 2 at the center of the belt conveyor, the hole forming assembly 3 is arranged on the inner end of the swing arm 2, and a guide hole 5 for guiding the traction rope is arranged in the hole forming assembly 3, and the hole forming assembly 3 is arranged to open the guide hole 5 when squeezed by the traction head, and the locking rod 4 is arranged to unlock the swing arm 2 after the guide hole 5 is opened.

[0024] The swing arm 2 and the hole forming assembly 3 are fixed as a whole on the frame of the pipe belt conveyor by the clamp 1, and the hole forming assembly 3 is located at the center of the pipe belt conveyor. Combined with the locking effect of the lock rod 4 on the swing arm 2, the hole forming assembly 3 and the swing arm 2 are fixed at this position. Before pulling the pipe belt, the traction rope is passed through each guide hole 5 in turn. At this time, the guide hole 5 can prevent the traction rope from rubbing against the surface of the roller by supporting and limiting the traction rope at various places, thereby preventing the roller from being damaged.

[0025] During the process of pulling the traction rope, when the traction head squeezes the hole-forming component 3, the hole-forming component 3 will operate to open the guide hole 5, providing a channel for the traction rope to escape from the guide hole 5. Moreover, after the hole-forming component 3 is actuated, the locking rod 4 unlocks the swing arm 2, and the swing arm 2 swings forward after being under pressure. During this process, the traction rope automatically escapes from the hole-forming component 3, and the swing arm 2 automatically leaves the pipe belt area to achieve avoidance.

[0026] The clamp 1 includes a clamp seat 1.1, a clamp plate 1.2 and a clamping bolt 1.3. The clamp plate 1.2 is slidably mounted on the clamp seat 1.1. The clamping bolt 1.3 is arranged between the clamp seat 1.1 and the clamp plate 1.2 and is used to control the clamp plate 1.2 and the clamp seat 1.1 to clamp and fix the frame of the pipe conveyor. The outer end of the swing arm 2 is rotatably mounted on the clamp seat 1.1.

[0027] By tightening the clamping bolts 1.3, the frame of the pipe-belt conveyor is clamped and fixed by the clamping plate 1.2 and the clamping seat 1.1, and then the guide seat is fixed on the pipe-belt conveyor as a whole.

[0028] The hole forming assembly 3 includes a first orifice plate 3.1 and a second orifice plate 3.2, and a first release opening 3.3 and a second release opening 3.4 for the detachment of the traction rope are respectively arranged on one side of the first orifice plate 3.1 and the second orifice plate 3.2. The first orifice plate 3.1 is fixedly arranged on the inner end of the swing arm 2, and the second orifice plate 3.2 is penetrated in the first orifice plate 3.1. A spiral groove 6 is arranged on the surface of the second orifice plate 3.2. The inner end of the guide rod passes through the first orifice plate 3.1 and is inserted into the spiral groove 6. When the second orifice plate 3.2 is squeezed by the traction head, it moves forward in the first orifice plate 3.1 and makes the first release opening 3.3 and the second release opening 3.4 overlap.

[0029] In the initial state, the second orifice plate 3.2 is extended backward on the first orifice plate 3.1, and the inner end of the locking rod 4 is in the front end of the spiral groove 6. The first release opening 3.3 and the second release opening 3.4 are staggered in the circumferential direction, so that the guide hole 5 is closed.

[0030] When inserting the towing rope and rotating the second orifice plate 3.2, during the rotation process of the second orifice plate 3.2, under the combined action of the spiral groove 6 and the locking rod 4, the second orifice plate 3.2 rotates and moves forward. When the first脱口 3.3 and the second脱口 3.4 are in a coincident state, the towing rope is inserted into the guiding hole 5, and then the second orifice plate 3.2 moves in the reverse direction to return to the initial state, closing the guiding hole 5.

[0031] During the process of towing the pipe belt, the towing head impacts the rear end of the second orifice plate 3.2, applying a forward thrust to the second orifice plate 3.2. During the process of the second orifice plate 3.2 moving forward within the first orifice plate 3.1, it rotates through the cooperation between the spiral groove 6 and the inner end of the locking rod 4 until the first脱口 3.3 and the second脱口 3.4 are in a coincident state. After that, when the swing arm 2 swings outward, it avoids the pipe belt and enables the towing rope to脱离 from the guiding hole 5.

[0032] On the swing plane of the first脱口 3.3 and the swing arm 2, and with the turning direction of the pipe belt machine as the reference, the swing arm 2 is located outside the center of the pipe belt machine. With such a setting, after the first脱口 3.3 and the second脱口 3.4 coincide, the towing rope can脱离 better from the guiding hole 5 under the action of tension. Especially during the swinging process of the swing arm 2, the orientations of the first脱口 3.3 and the second脱口 3.4 will not shift, ensuring that the towing rope脱离 the guiding hole 5.

[0033] The locking rod 4 is inserted through the swing arm 2. A locking spring 7 is arranged inside the swing arm 2. The locking spring 7 applies an inward extending force to the locking rod 4. The outer end of the locking rod 4 is bent to form a "匚"-shaped structure. A locking hole 8 is arranged on the fixture 1. The outer end of the locking rod 4 is inserted into the locking hole 8 from outside to inside. When the second orifice plate 3.2 moves forward after the first脱口 3.3 and the second脱口 3.4 coincide, it extrudes the locking rod 4 outward.

[0034] In the initial state, the elastic force of the locking spring 7 enables the inner end of the locking rod 4 to be stably inserted into the spiral groove 6, and the outer end of the locking rod 4 is inserted into the locking hole 8, fixing the swing arm 2. After the guiding hole 5 is opened, the second orifice plate 3.2 continues to move forward. At this time, the second orifice plate 3.2 extrudes the inner end of the locking rod 4, causing the locking rod 4 to move outward on the swing arm 2 and the outer end of the locking rod 4 to be pulled out of the locking hole 8, unlocking the swing arm 2.

[0035] During the process of the locking rod 4 moving outward, the locking spring 7 is compressed and stores energy continuously. After the swing arm 2 is unlocked, the elastic force of the locking spring 7 is applied to the second orifice plate 3.2 in the reverse direction through the locking rod 4. At this time, under the action of the elastic force, an instantaneous force is provided for the swinging of the swing arm 2, enabling the swing arm 2 to swing outward more quickly to avoid the rubber hose.

[0036] A wing plate 9 is fixedly installed on the surface of the second locking rod 4 at the rear end of the bolt groove, and an inclined groove 10 is opened in the wing plate 9. A straight groove 11 is provided at the rear end of the spiral groove 6. The rear end of the straight groove 11 is connected to the front end of the inclined groove 10. The inclined groove 10 is used to squeeze the locking rod 4 outward when the second orifice plate 3.2 moves forward.

[0037] During the forward displacement of the second clamping plate, the inner end of the locking rod 4 moves from the spiral groove 6 to the straight groove 11, and finally enters the inclined groove 10 from the straight groove 11. At this time, the inclined groove 10 exerts a force on the inner end of the locking rod 4, so that the locking rod 4 moves outward to compress the locking spring 7 and unlock the swing arm 2.

[0038] In addition, after the locking spring 7 is reset, the inner end of the locking rod 4 is displaced in the inclined groove 10 and will not enter the spiral groove 6. At this time, the locking rod 4 cooperates with the inclined groove 10 to maintain the locking effect on the second orifice plate 3.2, ensuring that the first release 3.3 and the second release 3.4 are always in an overlapping state during the swinging process of the swing arm 2.

[0039] The inner end of the swing arm 2 is provided with a through slot 12 for the wing plate 9 to pass through. The cooperation between the wing plate 9 and the through slot 12 further ensures that the second orifice plate 3.2 is limited during the swing arm 2 swinging outward, ensuring that the first release 3.3 and the second release 3.4 are always in an overlapping state.

[0040] When the locking rod 4 is located at the front end of the spiral groove 6, the rear end of the second orifice plate 3.2 is located in the pipe channel surrounded by the pipe conveyor rollers. This arrangement ensures a stable interval between the traction rope and the rollers to prevent the traction rope from wearing the rollers.

[0041] The swing arm 2 and the clamp 1 are located on the frame at the front side of the pipe belt channel surrounded by the pipe belt machine rollers, and the swing arm 2 is set with the inner end tilted upward by 45 degrees. In this way, when the reaction force of the locking spring 7 causes the swing arm 2 to swing outward, the self-biased weight of the swing arm 2 can assist the swing arm 2 to swing out of the pipe belt area more smoothly, and after the swing arm 2 swings, the swing arm 2 can use its own biased weight to more stably maintain the state outside the pipe belt area.

[0042] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
