Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor deviation adjustment, in particular to a belt conveyor deviation adjustment roller safety deviation adjustment device. Background Art

[0002] Among existing belt conveyors, the DTII fixed belt conveyor is the most common. This general-purpose, new series features continuous conveying equipment using cotton canvas, nylon, polyester canvas, and steel cord belts as traction elements. It is widely used in industries such as coal, metallurgy, mining, ports, chemicals, light industry, petroleum, and machinery to transport a variety of bulk materials and finished goods. Belt conveyors offer high transport capacity, high gradeability, low operating costs, and easy maintenance, facilitating automated transport system control. Belt conveyors operate based on the friction principle, using a continuous conveying mechanism with a rubber belt serving as both the traction and load-bearing mechanism. The belt wraps around a drive roller and a bend roller, forming an endless, endless belt. The belt is supported on idlers at the top and bottom, and a tensioning device applies a certain tension to the belt. During operation, the friction between the drive roller and the belt drives the belt.

[0003] Among them, rollers are devices used to support the conveyor belt and the materials carried on the conveyor belt, ensuring the stable operation of the conveyor belt. Common rollers include trough rollers, trough forward-tilting rollers, transition rollers, parallel upper roller buffer rollers, deviation adjustment rollers, and return branch (lower branch) rollers. There are two types of deviation adjustment rollers, friction type and conical type. They can prevent the conveyor belt from deviating and play a role in neutralizing the deviation. Both upper and lower branches can be used. Among them, the most common deviation adjustment rollers are movable trough deviation adjustment rollers (friction type). After the belt deviates, the operator must reach into the guardrail to turn the trough deviation adjustment roller to complete the belt correction, which increases the safety risk of the operator being caught in the belt conveyor.

[0014] Beneficial effects of one or more of the above technical solutions:

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-2 , describing the specific implementation of this embodiment.

[0021] like Figure 1 As shown, the embodiment of the utility model provides a belt conveyor deviation adjustment roller safety adjustment device, comprising:

[0022] A trough roller frame 1 and a roller group bracket 2, wherein the roller group bracket 2 is rotatably connected to the trough roller frame 1 via a rotating device 3; a middle roller 4 and two side rollers 5 are provided above the trough roller frame 1, wherein the middle roller 4 is arranged horizontally, and the two side rollers 5 are symmetrically arranged at both ends of the middle roller 4 and are installed obliquely;

[0023] The deflection adjustment operating rod 6 includes an integrally formed operating rod 61 , an upper deflection adjustment rod 62 and a lower deflection adjustment rod 63 ; the end of the lower deflection adjustment rod 63 is fixed to the middle position of the inclined side of the trough roller frame 1 .

[0024] As a further technical solution, the middle roller 4 and the two side rollers 5 are friction grooved deflection adjusting rollers. The friction grooved deflection adjusting rollers can prevent the conveyor belt from deviating and play a role in neutralizing the deviation.

[0025] As a further technical solution, the lower deflection adjustment rod 63 is fixed to the trough roller frame 1 by a deflection adjustment device fixing clamp 7 and a fixing bolt 8.

[0026] Preferably, the lower deflection adjustment rod 63 is 300 mm long, allowing it to extend 50 mm beyond the guardrail. The upper deflection adjustment rod 63 is 650 mm long, and the operating rod is 300 mm long. The length of the inclined groove on one side of the trough-shaped roller frame 1 is 570 mm. It should be noted that the length of the deflection adjustment operating rod 6 can be adjusted according to actual conditions such as the guardrail length. The length setting here is only a preferred method of the present invention.

[0027] The utility model installs an adjustment operating lever 6 on one side of the trough-type roller frame 1. When the belt on the conveyor deviates, the operator can directly operate the adjustment operating lever 6 to cause relative displacement between the roller and the belt, generate displacement friction, and then realize belt deviation correction.

[0028] The lower deflection adjustment rod 63 is in the same horizontal direction as the side roller 5 closest to it among the two side rollers 5, the upper deflection adjustment rod 62 is approximately perpendicular to the plane direction of the roller group bracket 2, and the operating rod 61 starts to tilt upward from the end connected to the upper deflection adjustment rod 62.

[0029] Preferably, the angle formed by the tilt direction of the operating lever 61 and the inclined groove surface fixed thereto in the trough roller frame 1 is 35°, and the angle formed by the tilt direction of the operating lever 61 and the plane direction of the trough roller frame 1 is 25°. The design of the deviation adjustment operating lever in the present invention makes good use of the lever principle, which can reduce the force required to correct the deviation of the trough deviation adjustment roller. In particular, when the trough deviation adjustment roller is stuck after a long period of use, the advantage of reducing the difficulty and intensity of human operation will be more obvious.

[0030] As a further technical solution, a roller bracket 9 is provided at the end of the two side rollers 5 that is close to the center roller 4, and a side bracket 10 is provided at the end of the two side rollers 5 that is far from the center roller 4. The roller bracket 9 is vertically inserted into the groove-shaped roller bracket 1, and the upper end of the roller bracket 9 is sloped, with its sloped surface facing the side roller 5 of the two side rollers 5 that is in contact with it. The back of the sloped surface of the roller bracket 9 is provided with a roller fixing bracket 91 for fixing the center roller 4. The design of the upper end of the roller bracket 9 being sloped, with its sloped surface facing the side roller 5 of the two side rollers 5 that is in contact with it, can maximize the contact between the rollers 5 on both sides and the roller fixing bracket 91, thereby enhancing the fixing strength of the rollers on both sides.

[0031] As a further technical solution, the rotating device includes a central axis of the deflection adjustment roller group, a bearing seat and a bearing; the bearing seat is installed on the roller group bracket, the bearing is installed in the bearing seat, and the central axis of the deflection adjustment roller group is installed on the grooved roller frame and connected to the bearing.

[0032] As a further technical solution, both ends of the roller group bracket are fixed to the frame of the belt conveyor by bolts.

[0033] The utility model discloses a belt conveyor deflection adjustment roller safety adjustment device. When the conveyor belt deviates, it can make corresponding adjustments according to the deflection direction of the belt. Specifically, when the conveyor belt deviates to the right, the adjustment lever can be turned in the direction of the coal flow (the direction of belt rotation) to correct the belt to the right; when the conveyor belt deviates to the left, it can be turned in the opposite direction of the coal flow to correct the belt to the left. Therefore, when the belt deviates, the operator no longer needs to reach into the guardrail to adjust the grooved deflection adjustment roller to correct the belt, greatly reducing the safety risk of the operator being caught in the belt conveyor.

[0034] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
