Description

Technical Field

[0001] The utility model belongs to the technical field of equipment maintenance, and in particular relates to a belt supporting device for a belt conveyor. Background Art

[0002] Belt conveyors are widely used in metallurgy, coal, transportation, hydropower, chemical industry and other departments because of their large conveying capacity, simple structure, convenient maintenance, low cost and strong versatility. Belt conveyors mainly have problems such as deviation, spillage, belt slippage and reducer shaft breakage, which require shock absorption, tension fluctuation reduction and overspeed slippage protection.

[0003] The belt of the belt conveyor is supported by rollers. When a roller fails during operation, it needs to be repaired or replaced. Since the roller supports the belt, the belt needs to be propped up and separated from the roller when repairing the roller, and then the roller needs to be repaired or replaced. Since the belt is in a tensioned state, it takes a lot of force to support the belt. In actual production, there is no dedicated belt support tool. Usually, tools with a certain length such as prying are used to support the belt, and workers need to hold it, which consumes manpower and has certain safety risks (such as slipping of the pry bar, which can injure people). Utility Model Content

[0004] The utility model aims to provide a belt conveyor belt supporting device, by which the belt supporting difficulty can be reduced and the construction risk in the process of roller maintenance or replacement can be reduced.

[0005] The utility model adopts the following technical scheme: a belt conveyor belt support device comprises a support plate, the top surface of which is a plane;

[0006] A screw is fixedly arranged at the bottom of the support plate;

[0007] A sleeve is sleeved outside the screw rod, an adjusting nut is coaxially arranged on the sleeve, and the adjusting nut is threadedly connected to the screw rod;

[0008] The bottom of the casing is connected to the bottom plate;

[0009] A force applying rod is arranged outside the sleeve.

[0010] Furthermore, the bottom plate and the sleeve are connected via a bearing.

[0011] Furthermore, a fixing rod coaxial with the sleeve is arranged on the bottom plate, the fixing rod is mounted on the inner ring of the bearing, and the sleeve is mounted on the outer ring of the bearing.

[0012] Furthermore, the number of the adjusting nuts is at least two, and they are arranged at intervals up and down.

[0013] Furthermore, the screw rod is arranged vertically to the supporting plate.

[0014] Furthermore, a first anti-slip layer is provided on the top surface of the support plate.

[0015] Furthermore, the number of the force applying rods is at least two, and the force applying rods are circumferentially spaced outside the sleeve.

[0016] Furthermore, a second anti-slip layer is provided at the bottom of the base plate.

[0017] The beneficial effect of the utility model is that the support plate is installed at one end of the screw rod and is connected to the sleeve through an adjusting nut on the outside. When the belt needs to be supported, the sleeve is rotated to make the screw rod extend and abut against the belt, and the sleeve is continued to be rotated until the belt is separated from the roller, thereby facilitating the maintenance or replacement of the roller.

[0022] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0023] The utility model discloses a belt conveyor belt support device, such as Figure 1 As shown, it includes a support plate 10, the top surface of the support plate 10 is a plane; a screw is fixedly arranged at the bottom of the support plate 10; a sleeve 30 is sleeved on the outside of the screw, an adjusting nut 20 is coaxially arranged on the sleeve 30, and the adjusting nut 20 is threadedly connected to the screw; the bottom of the sleeve 30 is connected to the bottom plate 50; a force rod 40 is arranged on the outside of the sleeve 30.

[0024] The utility model installs a support plate 10 at one end of the screw rod, and is connected to the sleeve 30 through an adjusting nut 20 on the outside. When the belt needs to be supported, the sleeve 30 is rotated to make the screw rod extend and abut against the belt 70, and the sleeve 30 is continued to be rotated until the belt 70 is separated from the roller 80, so that the roller 80 can be easily repaired or replaced.

[0025] The purpose of the support plate 10 is to support the belt 70, that is, to ensure the stability of the support, so its top surface is flat, which can be easily fitted with the belt 70. At the same time, in order to increase stability, the top surface of the support plate 10 needs to have an area of ​​a certain size to increase the contact surface and improve the support stability.

[0026] In addition, in order to further increase the support stability, the screw rod is vertically arranged to the support plate 10 , thereby ensuring that the top surface of the support plate 10 is evenly stressed.

[0027] Preferably, the adjusting nut 20 can be installed on the top of the sleeve 30, and the two are welded and firmly connected. At the same time, the adjusting nut 20 and the screw cooperate with each other. Based on the principle of the ball screw, when the sleeve 30 (i.e., the adjusting nut 20) is rotated, the bottom of the sleeve 30 will be against the ground or the bracket, and the support plate 10 will be against the belt 70, so that the rotary motion is converted into a linear motion, which is convenient and labor-saving.

[0028] Moreover, by providing the force rod 40, the sleeve 30 can be rotated more labor-savingly by the lever principle. The number of the force rods 40 is at least two, and they are arranged outside the sleeve 30 at circumferential intervals. In one embodiment, as Figure 1 As shown, there are three force application rods 40, which can be operated by both hands.

[0029] In a specific implementation, the bottom plate 50 is connected to the sleeve 30 via a bearing 60. This can prevent the bottom plate 50 from rotating synchronously with the sleeve 30, thereby increasing the operability of the device.

[0030] More specifically, Figure 2 As shown, a fixing rod 51 coaxial with the sleeve 30 is provided on the bottom plate 50, the fixing rod 51 is mounted on the inner ring of the bearing 60, and the sleeve 30 is mounted on the outer ring of the bearing 60. Of course, the sleeve 30 can also be fixed on the inner ring of the bearing, and a mounting ring can be provided on the bottom plate 50 to be sleeved on the outer ring of the bearing 60. Both methods can be implemented and are applicable to different working conditions.

[0031] In the embodiment of the utility model, the number of the adjusting nuts 20 is at least two, and they are spaced apart from each other. Since the screw needs to drive the support plate 10 to support the belt 70, the screw needs to have a certain length. At this time, in order to prevent one adjusting nut 20 from being subjected to excessive force, at least one adjusting nut 20 can be added, so that the radial force generated by the screw can be shared by the adjusting nuts 20 spaced apart from each other, thereby enhancing the supporting performance of the device.

[0032] Since the belt needs to be supported, a first anti-skid layer is provided on the top surface of the support plate 10, and a second anti-skid layer is provided on the bottom of the bottom plate 50. The anti-skid layer can be made of a material having a large friction with the belt, such as a rubber material. This can increase the fixing force at the upper and lower ends of the device, and is particularly suitable for rollers 80 installed obliquely.

[0033] By using the device of the utility model, the number of people for replacing the roller 80 is reduced from three to two, saving 10 labors per month. The direct benefit is 2,800 yuan if each worker is paid 280 yuan.

[0034] In addition, if Figure 3 The figure is a schematic diagram of the state when the inclined roller 80 is replaced. The belt 70 and the roller 80 in the figure are arranged obliquely. When the roller 80 needs to be replaced, the base plate 50 is placed against the roller bracket, and the support plate 10 is placed against the ground of the belt 70. Then, the sleeve 30 is rotated in the forward direction by the force rod 40, and the screw will rise upward, thereby supporting the belt 70 to rise until the belt 70 and the roller 80 are separated. Then, the roller 80 is repaired or replaced. After the operation is completed, the sleeve 30 is rotated in the reverse direction, the screw descends, and the belt 70 slowly falls onto the repaired or replaced roller 80, thereby completing the repair or replacement of the roller 80.
