Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyor state detection, in particular to a belt speed protection test support mechanism. Background Art

[0002] Belt conveyors, also known as rubber belt conveyors, are primarily used to transport raw coal, gangue, and other materials underground in coal mines. Belt conveyors are typically equipped with a roller-type anti-slip protection mechanism that detects belt slippage and sends a belt detection signal to the control system.

[0003] When inspecting the roller-type anti-skid protection mechanism, a worker is usually required to hold a long rod (such as a drill rod) to separate the inspection device from the belt, which may bring certain safety hazards. Utility Model Content

[0009] Furthermore, the vertical hook includes a hook body and a straight rod at the bottom, and the top end of the straight rod is fixedly connected to the cross rod.

[0010] Furthermore, the support structure includes a U-shaped bracket arranged on the belt rack, and a support member is arranged between two vertical plates of the U-shaped bracket;

[0011] Wherein, the belt racks are arranged on both sides of the belt.

[0013] Furthermore, a first height of the top end of the vertical plate is greater than a second height of the support rod located at the top.

[0014] Furthermore, the difference between the first height and the second height is greater than the thickness of the crossbar.

[0015] The beneficial effect of the utility model is that the utility model has a vertical hook and a cross bar detachably connected to the roller frame for lifting the roller, and the cross bar can be lifted as needed to achieve the separation of the roller and the belt, thereby realizing the belt speed protection test and greatly increasing the operational safety.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] The utility model discloses a belt speed protection test support mechanism, comprising a vertical hook 33 for detachably connecting to a roller frame 44 of a roller type anti-skid protection mechanism; the top of the vertical hook 33 is connected to a transversely arranged crossbar 32, and both ends of the crossbar 32 are arranged on a support structure; and support members of different heights are arranged on the support structure.

[0023] The utility model has a vertical hook and a cross bar detachably connected to the roller frame for lifting the roller, and the cross bar can be lifted as needed to realize the separation of the roller and the belt, thereby realizing the belt speed protection test and greatly improving the operation safety.

[0024] like Figure 1 As shown, the roller-type anti-slip protection mechanism includes a roller 45 in rolling contact with the belt. The roller 45 is installed on a roller frame 44. The roller frame 44 is connected to the gantry 41 through a connecting rod 43 and a connecting hinge 42 in turn. The two ends of the gantry 41 are fixed on the belt frame 20.

[0025] When the belt 10 rotates normally, the roller 45 rotates with it, and the sensor on the roller frame 44 detects the rotation of the roller and sends a signal to the control system, and the control system believes that the belt conveyor is working normally. When the belt 10 stops rotating, the control system believes that the belt conveyor has a fault.

[0026] In one embodiment, a hanging ring 34 is further provided on the roller frame 44. The hanging ring 34 is used to cooperate with the hook body at the bottom of the vertical hook 33 to achieve a detachable connection between the roller anti-slip protection mechanism and the belt speed protection test support mechanism. The design of the hanging ring 34 allows the vertical hook 33 to cooperate with each other in a predictable manner to test the disassembly of the belt speed protection test support mechanism and the roller anti-slip protection mechanism. When not testing, the two are separated and do not affect normal testing work. When testing is underway, the two are connected to achieve separation of the roller 45 and the vertical hook 33.

[0027] The vertical hook 33 includes a hook body at the bottom and a straight rod, the top of which is fixedly connected to the crossbar 32. The design of the straight rod can simplify the structure, save consumables, and maintain the balance of the crossbar 32, increase the belt speed, and protect the balance of the test support mechanism.

[0028] As a specific implementation, the support structure includes a U-shaped bracket 31 mounted on the belt frame 20, with a support member disposed between the two uprights of the U-shaped bracket 31. The belt frame 20 is positioned on either side of the belt 10. This design fully utilizes the belt frame 20 as a support structure, eliminating the need for additional support structures and further reducing costs. In this embodiment, the belt frame 20 is actually the longitudinal beams on either side of the belt, serving as the original support structure of the belt conveyor.

[0029] The support member is a rod 35, which is detachably connected to the vertical plate. Since the support member only needs to provide support, it is designed in a rod shape to facilitate material retrieval and processing. Furthermore, the detachable connection between the rod 35 and the vertical plate allows the rod 35 to be installed only when needed and removed when not needed, facilitating operation and improving the safety of the belt conveyor. The straight rod 35 is essentially a movable latch, and can be made of a load-bearing component such as a bolt or iron rod. This allows the height of the crossbar 32 to be adjusted with a simple insertion and removal.

[0030] The first height of the top of the vertical plate is greater than the second height of the top support rod 35. The difference between the first and second heights is greater than the thickness of the crossbar. Since crossbar 32 is simply attached to support rod 35, to prevent crossbar 32 from slipping out due to shaking, the vertical plate can be used as a baffle to increase belt speed and maintain the stability of the test support mechanism.

[0031] like Figure 1As shown, a gantry 20 is mounted on the belt frame 20 on either side of the belt 10. The top of a connecting rod 43 is connected to the gantry 20 via a connecting hinge 42. The two connecting plates of the connecting hinge 42 can rotate relative to each other, allowing rollers 45 to float up and down to accommodate the floating amount of the belt. The lower end of the connecting rod 43 is connected to a roller frame 44, which is mounted on a roller 45 that can rotate with the belt 10. A sensor for measuring the roller's rotational speed is also mounted on the roller frame 44.

[0032] When the belt speed protection test support mechanism is operating normally, the crossbar 32 of the roller type anti-skid protection mechanism is located at a lower position and does not interfere with the roller frame 44. Figure 2 As shown, when the belt speed protection test support mechanism is tested and repaired, the vertical hook 33 is connected to the hanging ring 34 on the roller frame 44, and the cross bar 32 is lifted and then placed at a higher position. At this time, the roller frame 44 moves upward with the roller 45, thereby separating the roller 45 and the belt, and the control system is tested.

[0033] In addition, it should be noted that while the vertical hook 33 drives the roller frame 44 to move upward, it rotates along the axis connected to the hinge 42. At this time, the roller anti-slip protection mechanism will have a certain displacement. However, since there is a horizontal distance between the two vertical plates of the U-shaped bracket 31, the cross bar 32 can move laterally to adapt to the displacement caused by the rotation of the vertical hook 33.

[0034] In addition, in the embodiment of the present invention, the belt upper roller bracket can be used as the gantry 41, which can minimize the structural changes to the belt conveyor.
