Description

Technical Field

[0001] The utility model relates to the field of belt conveyors, in particular to a belt deviation correcting device for belt conveyors. Background Art

[0002] Belt conveyor (also called "belt conveyor") is a kind of material conveying equipment with high operating efficiency. It is widely used in the fields of electricity, metallurgy, chemical industry, coal, port, mining, building materials, etc. due to its advantages of large conveying capacity, long conveying distance and stable conveying. The important components of belt conveyor are rollers and roller frames. The main function of rollers and roller frames is to support the belt and reduce the running resistance to ensure the smooth operation of the conveyor belt.

[0003] Belt deviation is the most common fault in the operation of belt conveyors. In actual operation, belt deviation can easily cause belt rollover and cause safety hazards such as lateral tearing of the belt, which not only causes great damage to the belt conveyor itself, but also reduces the service life of the belt, seriously affecting production efficiency. When the belt deviates, it is often necessary to use a self-aligning roller for adjustment. However, the self-aligning rollers on the market currently need to be tightened and adjusted with ropes or wires after adjusting the deviation. The rope tightening is cumbersome, the operation is cumbersome, the efficiency is low, and the correction effect is unstable. For example, a belt roller deviation adjustment device with authorization announcement number CN 213595270 U adjusts the deviation by cooperating with a self-aligning roller and a wire rope, and then uses a locking mechanism to fix the deviation after the deviation. This deviation adjustment method is too cumbersome, complex in structure, and inefficient. Summary of the invention

[0004] The utility model aims to overcome the deficiencies of the prior art and proposes a belt deviation correction device for a belt conveyor, which can realize belt deviation correction and fix the deviation correction result in a simple structure and manner, has high efficiency and is easy to operate.

[0005] In order to achieve the above objectives, the utility model proposes the following technical solutions:

[0006] A belt deviation correction device for a belt conveyor comprises a roller frame, a deviation adjustment frame, a transmission belt bracket, an adjustment chuck and a movable handle.

[0007] The roller support frame is used for installing rollers, and a rotating shaft is provided at the bottom of the roller support frame and is installed on the transmission belt bracket.

[0008] The deflection adjustment frame is arranged on both sides of the roller frame, and the center lines of the deflection adjustment frame and the roller frame are coplanar, forming a deflection adjustment rotation plane that rotates around the axis of the rotating shaft, so that the deflection adjustment frame and the roller frame rotate synchronously around the rotating shaft. The deflection adjustment frame is provided with a hinge shaft, and the axis of the hinge shaft is perpendicular to the deflection adjustment rotation plane.

[0009] The adjusting chuck is arranged on the belt bracket and is below the hinge shaft. A plurality of card slots are arranged on the adjusting chuck, and rough surfaces are arranged on both sides inside the card slots.

[0010] The movable handle includes a handle frame, a rotating body and a clamping frame. The handle frame is connected to the clamping frame through the rotating body. The rotating body is hinged to the hinge shaft and can only rotate around the hinge shaft and cannot move along the hinge shaft. The movable handle rotates synchronously with the deviation adjusting frame.

[0011] Rough surfaces are arranged on both sides of the free end of the clamping frame that contact the card slot. During the rotation of the rotating body around the hinge shaft, the free end of the clamping frame can be inserted into the card slot of the adjusting chuck. The clamping frame and the card slot cooperate with each other so that the clamping frame can be inserted into the card slot and is not easy to slide out. Applying a certain rotational torque on the handle frame can cause it to disengage from the card slot. The card slots on the adjusting chuck correspond to the clamping frames at different deviation adjusting angles, and at different deviation adjusting angles, the clamping frame can be inserted into the corresponding card slot.

[0012] Preferably, the center line of the handle frame, the center of the rotating body and the center line of the clamping frame are in the same plane, forming a handle rotation plane, and the handle rotation plane is parallel to the deviation adjustment rotation plane.

[0013] Preferably, the handle rotation plane coincides with the deviation adjustment rotation plane.

[0014] Preferably, the center of the adjusting chuck is coaxial with the rotating shaft, and the center line of the card slot is arranged radially.

[0015] Preferably, the number of the card slots is an odd number of more than 3, and the center line of the card slot in the middle position is perpendicular to the belt transmission direction.

[0016] Preferably, the free end of the handle frame is provided with anti-slip lines for holding by hand.

[0017] Preferably, the adjusting chuck is in a fan shape.

[0018] Specifically, in the initial state, that is, the deviation adjustment rotation plane where the deviation adjustment frame is located is perpendicular to the belt transmission direction, and the clamping frame is inserted into the corresponding card slot.

[0019] When deviation adjustment is required, first judge the deviation adjustment direction and deviation adjustment angle according to the deviation direction of the belt, then hold the free end of the handle frame and apply a torque to make the movable handle rotate, causing the clamping frame to disengage from the card slot, and then rotate in the deviation adjustment direction. The movable handle drives the deviation adjustment frame to rotate. After rotating a certain deviation adjustment angle, stop rotating, apply a torque to the handle frame, and the movable handle rotates in the reverse direction, making the clamping frame inserted into the corresponding card slot, that is, one deviation adjustment is completed and the deviation adjustment state is fixed.

[0020] To strengthen the fixed state of the deviation adjustment state, the staff can continue to apply a certain torque to the handle holder, so that the engaging holder is stably engaged in the card slot, increasing stability and reliability.

[0021] Judging the deviation adjustment direction and deviation adjustment angle according to the deviation direction of the belt is the content known to those skilled in the art and does not require additional creation.

[0022] The beneficial effects of the present utility model are as follows:

[0023] By arranging a movable handle that rotates synchronously on the deviation adjustment frame in the present utility model, rotating the movable handle can achieve the deviation adjustment effect of the deviation adjustment frame on the belt.

[0024] By arranging an adjustment chuck on the belt conveyor bracket in the present utility model, the adjustment chuck cooperates with the movable handle. After the movable handle rotates the deviation adjustment frame to a specified deviation adjustment angle and is engaged in the adjustment chuck, the fixation of the deviation correction effect can be achieved.

[0025] Adopting the above solution, the present utility model can achieve belt deviation correction and the fixation of the deviation correction result with a simple structure and method, with high efficiency and easy operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] As Figure 1 shown, a belt deviation rectifying device for a belt conveyor includes a roller frame 1, an adjustment frame 2, a conveyor belt bracket 4, an adjustment chuck 5, and a movable handle 6.

[0036] The roller frame 1 is used for installing rollers. A rotating shaft 3 is provided at the bottom of the roller frame 1 and is installed on the conveyor belt bracket 4.

[0037] The adjustment frames 2 are respectively arranged on both sides of the roller frame 1. The center lines of the adjustment frames 2 and the roller frame 1 are coplanar, forming an adjustment rotation plane that rotates around the axis of the rotating shaft 3, so that the adjustment frames 2 and the roller frame 1 rotate synchronously around the rotating shaft 3. An articulated shaft 21 is provided on the adjustment frame 2, and the axis of the articulated shaft 21 is perpendicular to the adjustment rotation plane, as Figure 3 shown.

[0038] The adjustment chuck 5 is arranged on the conveyor belt bracket 4 and is located below the articulated shaft 21. A plurality of card slots 51 are provided on the adjustment chuck 5, and rough surfaces are provided on both sides inside the card slots 51.

[0039] As Figure 2As shown, the movable handle 6 includes a handle frame 61, a rotating body 62, and a engaging frame 63. The handle frame 61 is connected to the engaging frame 63 through the rotating body 62. The rotating body 62 is hinged to the hinge shaft 21. The rotating body 62 can only rotate around the hinge shaft 21 and cannot move along the hinge shaft 21. The movable handle 6 rotates synchronously with the biasing frame 2.

[0040] On both sides of the free end of the engaging frame 63 that contact the card slot 51, there are rough surfaces. During the rotation of the rotating body 62 around the hinge shaft 21, the free end of the engaging frame 63 can be inserted into the card slot 51 of the adjusting chuck 5. The engaging frame 63 and the card slot 51 cooperate with each other so that the engaging frame 63 can be inserted into the card slot 51 and is not easy to slip out. Applying a certain torque on the handle frame 61 can cause it to disengage from the card slot 51. The card slot 51 on the adjusting chuck 5 corresponds to the engaging frame 63 at different biasing angles. At different biasing angles, the engaging frame 63 can be inserted into the corresponding card slot 51, as Figure 3 shown.

[0041] The center line of the handle frame 61, the center of the rotating body 62, and the center line of the engaging frame 63 are in the same plane, forming a handle rotation plane. The handle rotation plane coincides with the biasing rotation plane.

[0042] The center of the adjusting chuck 5 is coaxial with the rotating shaft 3, and the center line of the card slot 51 is arranged radially.

[0043] The number of the card slots 51 is an odd number greater than 3. The center line of the card slot 51 in the middle position is perpendicular to the belt transmission direction.

[0044] The free end of the handle frame 61 is provided with anti-slip lines for hand gripping.

[0045] The adjusting chuck 5 is in a fan shape.

[0046] In the initial state, that is, when the biasing frame 2 is in the biasing rotation plane perpendicular to the belt transmission direction, the engaging frame 63 is inserted into the corresponding card slot 51.

[0047] When biasing is required, first determine the biasing direction and biasing angle according to the deviation direction of the belt. Then hold the free end of the handle frame 61 and apply a torque to make the movable handle 6 rotate, causing the engaging frame 63 to disengage from the card slot 51. Then rotate in the biasing direction. The movable handle 6 drives the biasing frame 2 to rotate. After rotating a certain biasing angle, stop rotating. Apply a torque to the handle frame 61, and the movable handle 6 rotates in the reverse direction, making the engaging frame 63 inserted into the corresponding card slot 51, that is, completing one biasing and fixing the biasing state.

[0048] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
