Technical Field

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

[0002] Belt conveyors, also known as rubber belt conveyors, are mainly used for the transportation of raw coal, gangue, etc. in coal mines. Belt conveyors are usually equipped with roller-type anti-slip protection mechanisms, which are used to detect belt transfer and send belt detection signals to the control system.

[0003] When testing the roller type anti-skid protection mechanism, the staff is usually required to hold a long rod (such as a drill rod) to separate the detection device from the belt, which may bring certain safety hazards. Summary of the invention

[0004] The object of the present invention is to provide a belt speed protection test support mechanism to achieve separation of a roller and a belt during the detection process.

[0005] The present invention adopts the following technical scheme: a belt speed protection test support mechanism, comprising a vertical hook for detachably connecting with a roller frame of a roller type anti-skid protection mechanism;

[0006] The top of the vertical hook is connected with a horizontally arranged crossbar, and both ends of the crossbar are arranged on the supporting structure;

[0007] The supporting structure is provided with supporting members of different heights.

[0008] Furthermore, it also includes a hanging ring arranged on the roller frame, which is used to cooperate with the hook body at the bottom of the vertical hook to achieve a detachable connection between the roller anti-slip protection mechanism and the belt speed protection test support mechanism.

[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] Further, the support structure includes a U-shaped bracket arranged on the belt frame, 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.

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The present invention 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 present invention 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 from the belt, thereby realizing the belt speed protection test, which greatly increases the operational safety.

[0024] like Figure 1 As shown, the roller type anti-skid protection mechanism includes a roller 45 that is in rolling contact with the belt. The roller 45 is installed on a roller frame 44. The roller frame 44 is connected to a gantry 41 through a connecting rod 43 and a connecting hinge 42 in turn. Both 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 included on the roller frame 44, and the hanging ring 34 is used to cooperate with the hook body at the bottom of the vertical hook 33 to realize the detachable connection between the roller type anti-skid protection mechanism and the belt speed protection test support mechanism. Through the design of the hanging ring 34, the vertical hook 33 can be expected to cooperate to test the disassembly of the belt speed protection test support mechanism and the roller type anti-skid protection mechanism. When the test is not carried out, the two are in a separated state and will not affect the normal detection work. When the test is carried out, the two are connected to realize the separation of the roller 45 and the vertical hook 33.

[0027] The vertical hook 33 includes a hook body and a straight rod at the bottom, and the top of the straight rod is fixedly connected to the cross bar 32. Through the design of the straight rod, the structure can be simplified, consumables can be saved, and the balance of the cross bar 32 can be maintained, and the balance of the belt speed protection test support mechanism can be increased.

[0028] As a specific implementation form, the support structure includes a U-shaped bracket 31 arranged on the belt frame 20, and a support member is arranged between two vertical plates of the U-shaped bracket 31; wherein the belt frame 20 is arranged on both sides of the belt 10. Such a design can utilize the belt frame 20 as a support structure and make full use of it, without having to design an additional support structure, further reducing costs. In this embodiment, the belt frame 20 is actually the longitudinal beams on both sides of the belt, which is the original support structure of the belt conveyor.

[0029] The support member is a support rod 35, and the support rod 35 is detachably connected to the vertical plate. Since the support member only needs to provide support, it is designed to be rod-shaped, which is convenient for material collection and processing. At the same time, through the detachable connection between the support rod 35 and the vertical plate, the support rod 35 can be installed only when needed and removed when not needed, which is convenient for operation and improves the safety performance of the belt conveyor. The straight rod 35 is actually a movable latch, and bolts, iron rods and other parts with certain load-bearing capacity can be used, so that the height adjustment of the cross bar 32 can be achieved by simply plugging and unplugging.

[0030] The first height of the top of the vertical plate is greater than the second height of the support rod 35 at the top. The difference between the first height and the second height is greater than the thickness of the crossbar. Since the crossbar 32 is only overlapped on the support rod 35, in order to prevent the crossbar 32 from falling out due to shaking, through the above design, the vertical plate can be used as a baffle to increase the belt speed and protect the stability of the test support mechanism.

[0031] like Figure 1As shown, a gantry 20 is provided on the belt frame 20 located on both sides of the belt 10, and the top of the connecting rod 43 is connected to the gantry 20 through a connecting hinge 42, and the two connecting plates of the connecting hinge 42 can rotate relative to each other so that the roller 45 can have an up and down floating amount to adapt to the floating amount of the belt. The lower end of the connecting rod 43 is connected to a roller frame 44, and the roller frame 44 is installed with a roller 45 that can rotate with the belt 10, and a sensor for measuring the roller speed is installed 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, so that the roller 45 and the belt are separated, 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 about 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 lateral 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.
