Description

Technical Field

[0001] This utility model belongs to the field of belt roller maintenance technology, specifically an auxiliary tool for replacing belt rollers. Background Technology

[0002] Belt conveyors mainly consist of a frame, conveyor belt, belt rollers, tensioning device, and transmission device. They are used to transport loose materials or packaged goods. Depending on the conveying process requirements, they can be used individually, in multiple units, or combined with different conveying equipment to form horizontal or inclined conveying systems. The rollers, as the support system for the belt, can bear the weight of the material and support the belt, ensuring its normal operation. When the belt runs on the rollers, the rollers must withstand significant impact loads. Therefore, the quality of the rollers directly affects the operation of the belt conveyor, belt wear, and service life. To ensure the normal operation of the belt conveyor, regular maintenance of the belt rollers is necessary.

[0003] When replacing a belt pulley, it is usually necessary to lift the belt to detach it from the pulley for easier operation, thus providing some operating space for the replacement. Currently, it is usually done by two people: one uses a pry bar to lift the belt while the other replaces the pulley. This not only results in high labor costs but also puts a lot of physical strain on the workers as they keep the belt lifted. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides an auxiliary tooling for replacing belt rollers. First, the supporting angle iron is placed downwards against the machine frame. Then, the top plate is placed against the bottom surface of the belt. The belt is clamped by the clamping frame and the pressing assembly. Subsequently, the first operating lever is rotated, which drives the rotating frame to rotate. As the rotating frame rotates, it drives the first screw and the second screw to move away from each other, thereby lifting the belt and providing operating space for replacing the rollers. The entire process can be completed by only one person, reducing labor costs and eliminating the need for workers to constantly lift the belt, thus reducing labor intensity.

[0005] This utility model provides an auxiliary tooling for changing belt rollers, including a telescopic lifting assembly. The bottom end of the lifting assembly is provided with a supporting angle iron, which abuts against the frame. The top end of the lifting assembly is provided with a top plate, which abuts against the bottom surface of the belt.

[0006] Furthermore, the lifting assembly includes a rotating frame, with a first screw threadedly connected to the bottom end of the rotating frame. The first screw vertically penetrates the rotating frame and is fixedly connected to a supporting angle iron at its bottom end. A second screw is threadedly connected to the top end of the rotating frame. The second screw vertically penetrates the rotating frame and is fixedly connected to a top plate at its top end. The threads of the first screw and the second screw are in opposite directions.

[0007] Furthermore, a first operating lever is fixedly connected to both sides of the rotating frame.

[0008] Furthermore, a clamping frame is provided on the top surface of the top plate, and a pressing component is provided on the clamping frame. The pressing component presses the belt downward, and the belt is clamped between the pressing component and the top plate.

[0009] Furthermore, the clamping assembly includes a third screw threadedly connected to the clamping frame, the third screw vertically penetrating the clamping frame, a pressure plate at the bottom end of the third screw pressing the belt downwards, and a connecting block fixedly connected to the top end of the third screw, with multiple second operating levers fixedly connected to the connecting block.

[0010] Furthermore, a receiving groove is provided on the bottom surface of the clamping frame, and the pressure plate can be moved upward into the receiving groove.

[0011] Furthermore, the pressure plate is rotatably connected to the bottom end of the third screw.

[0012] Furthermore, the clamping frame is detachably mounted on the top plate. An installation groove is provided on the top surface of the top plate. The bottom end of the clamping frame is inserted into the installation groove. An installation bolt is horizontally inserted into the top plate. A threaded hole is also provided in the top plate. The installation bolt passes through the clamping frame and is screwed into the threaded hole. The installation bolt is threadedly connected to the top plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) When replacing the support roller, first place the support angle iron against the frame below, then place the top plate against the bottom surface of the belt, and then rotate the first operating lever. The first operating lever drives the rotating frame to rotate. Since the two ends of the rotating frame are respectively threaded with the first screw and the second screw, and the threads of the first screw and the second screw are opposite, the rotating frame will drive the first screw and the second screw to move away from each other while rotating, thereby lifting the belt and providing operating space for replacing the support roller. The whole process can be completed by one person, which reduces labor costs and eliminates the need for staff to keep lifting the belt, thus reducing labor intensity.

[0015] (2) Before lifting the belt, insert the belt between the clamping frame and the top plate, and then rotate the second operating rod. The second operating rod drives the third screw to rotate through the connecting block. The third screw moves downward while rotating, so the third screw drives the pressure plate to move downward. The pressure plate presses the belt down, and the belt is clamped between the pressure plate and the top plate, thereby fixing the belt and the top plate together. This ensures the stability of the belt when it is lifted and prevents the belt from detaching from the top plate when it is lifted. It also restricts the rotation of the second screw and prevents the second screw from rotating together when the rotating frame rotates.

[0016] (3) The clamping frame can be detachably installed on the top plate through the mounting slot and mounting bolts, which facilitates the maintenance and replacement of the clamping frame and the clamping assembly in the later stage. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The present invention will be described in detail with specific embodiments.

[0024] Reference Figures 1-3 The present invention provides an auxiliary tooling for replacing belt rollers, including a telescopic lifting component 3. The bottom end of the lifting component 3 is provided with a supporting angle iron 4, which abuts against the frame 1. The top end of the lifting component 3 is provided with a top plate 5, which abuts against the bottom surface of the belt 2.

[0025] The lifting assembly 3 includes a rectangular rotating frame 30. A first screw 31 is threaded to the bottom end of the rotating frame 30. The first screw 31 vertically penetrates the rotating frame 30 and is fixedly connected to the bottom end of the first screw 31 with the supporting angle iron 4. A second screw 32 is threaded to the top end of the rotating frame 30. The second screw 32 vertically penetrates the rotating frame 30 and is fixedly connected to the top plate 5 with the top end of the second screw 32. The threads of the first screw 31 and the second screw 32 are in opposite directions. A first operating rod 33 is fixedly connected to both sides of the rotating frame 30. The first operating rod 33 facilitates the operator to rotate the rotating frame 30.

[0026] When replacing the support roller, first place the support angle iron 4 against the lower frame 1, then place the top plate 5 against the bottom surface of the belt 2, and then rotate the first operating lever 33. The first operating lever 33 drives the rotating frame 30 to rotate. Since the two ends of the rotating frame 30 are respectively threaded with the first screw 31 and the second screw 32, and the threads of the first screw 31 and the second screw 32 are in opposite directions, the rotation of the rotating frame 30 will drive the first screw 31 and the second screw 32 to move away from each other, thereby lifting the belt 2 and providing operating space for replacing the support roller. The whole process can be completed by only one person, reducing labor costs, and the staff does not need to keep lifting the belt 2, reducing labor intensity.

[0027] An L-shaped clamping frame 6 is provided on the top surface of the top plate 5. A pressing component 7 is provided on the clamping frame 6. The pressing component 7 presses down on the belt 2, and the belt 2 is clamped between the pressing component 7 and the top plate 5.

[0028] The clamping assembly 7 includes a third screw 70 threadedly connected to the clamping frame 6. The third screw 70 extends vertically through the clamping frame 6. A pressure plate 71 is provided at the bottom end of the third screw 70. The pressure plate 71 is rotatably connected to the bottom end of the third screw 70. The pressure plate 71 presses the belt 2 downward. A connecting block 72 is fixedly connected to the top end of the third screw 70. Multiple second operating rods 73 are fixedly connected to the connecting block 72.

[0029] Before lifting the belt 2, insert the belt 2 between the clamping frame 6 and the top plate 5. Then rotate the second operating lever 73. The second operating lever 73 drives the third screw 70 to rotate through the connecting block 72. As the third screw 70 rotates, it moves downward. Therefore, the third screw 70 drives the pressure plate 71 to move downward. The pressure plate 71 presses the belt 2 down, and the belt 2 is clamped between the pressure plate 71 and the top plate 5, thereby fixing the belt 2 and the top plate 5 together. This ensures the stability of the belt 2 when it is lifted and prevents the belt 2 from detaching from the top plate 5 when it is lifted. It also restricts the rotation of the second screw 32 and prevents the second screw 32 from rotating together when the rotating frame 30 rotates.

[0030] A receiving groove 74 is provided on the bottom surface of the clamping frame 6. The pressure plate 71 can be moved upward into the receiving groove 74, thereby providing more space for the belt 2 to be inserted between the clamping frame 6 and the top plate 5, which facilitates the insertion of the belt 2.

[0031] The clamping frame 6 is detachably mounted on the top plate 5. A mounting groove 8 is provided on the top surface of the top plate 5. The bottom end of the clamping frame 6 is inserted into the mounting groove 8. A mounting bolt 9 is horizontally inserted into the top plate 5. A threaded hole 10 is also provided in the top plate 5. The mounting bolt 9 passes through the clamping frame 6 and is screwed into the threaded hole 10, thus threading the mounting bolt 9 into the top plate 5. The clamping frame 6 is detachably mounted on the top plate 5 via the mounting groove 8 and the mounting bolt 9, facilitating future maintenance and replacement of the clamping frame 6 and the clamping assembly 7.

[0032] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
