Description

Technical Field

[0001] The present application relates to the field of roller equipment, and in particular to a roller that is easy to assemble and disassemble. Background Art

[0002] A common routine maintenance task for belt conveyors involves replacing damaged rollers. However, for trough-type rollers, replacing the rollers in the load-bearing section typically requires three to four people using tools like crowbars or slings to lift the belt, and then other workers leaning over to replace the rollers between the upper and lower belts. Furthermore, replacing rollers in the belt where components such as the guide trough are installed requires first removing the guide trough and then replacing them according to the normal load-bearing section. After this, the guide trough must be reinstalled. Due to the influence of belt tension, the weight of the belt, and the components above the belt during roller replacement, replacing rollers is labor-intensive, inefficient, and can easily cause personal injury. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the present application provides a roller that is easy to assemble and disassemble.

[0004] The present application provides a roller that is easy to disassemble and assemble, which adopts the following technical solution:

[0005] A roller that is easy to disassemble and assemble comprises a crossbeam, support plates fixedly arranged at both ends of the crossbeam and a roller arranged on the support plates, wherein the support plates are provided with a slot for clamping the roller and a middle slot connected to the slot, and an abutment plate for supporting the roller is hinged in the middle slot.

[0006] A further technical solution is that a handle is provided on the outer side of the abutment plate; a step groove is provided on the outer periphery of the middle groove, and the free end of the abutment plate is fixed to the step groove by means of bolts.

[0007] A further technical solution is that the free end of the abutting plate is provided with a rounded structure.

[0008] This application has the following beneficial technical effects:

[0009] By setting a card slot and a middle slot on the support plate, and setting an abutment plate in the middle slot, when removing or installing the roller, the abutment plate can be opened to allow the roller to be embedded from below into a fixed position in the card slot, which helps to improve the efficiency of roller removal and replacement.

[0013] The technical solution in this application is further described in detail below with reference to the accompanying drawings.

[0014] The embodiment of the present application discloses a roller that is easy to disassemble and assemble. Figure 1 and Figure 2 A roller that is easy to disassemble and assemble includes a crossbeam 1, support plates 2 fixedly arranged at both ends of the crossbeam 1, and a roller 3 arranged on the support plate 2. The support plate 2 is provided with a slot 21 for clamping the roller 3 and a middle slot 22 connected to the slot 21, and an abutment plate 4 for supporting the roller 3 is hinged in the middle slot 22.

[0015] Among them, the crossbeam 1 is used to be fixed on the frame of the conveyor, and the support plate 2 supports the roller 3 through the clamping groove 21. The end of the roller shaft 31 of the roller 3 is a square structure, and the clamping groove 21 is a square groove to match the roller shaft 31 to clamp and fix the roller 3.

[0016] When the roller 3 is in normal working state, the roller shaft 31 of the roller 3 is clamped in the clamping groove 21 , and the abutment plate 4 is embedded in the middle groove 22 to abut and support the roller shaft 31 .

[0017] When the roller 3 needs to be disassembled and replaced, the roller 3 can be directly lifted upward to disengage the roller shaft 31 from the slot 21 to complete the disassembly; when the conveyor belt is supported on the roller 3, the two abutment plates 4 can be rotated open, and the roller shaft 31 can slide downward into the wider middle groove 22. At this time, the roller 3 can be removed from the support plate 2 in an inclined state.

[0018] During installation, the roller shaft 31 of the new roller 3 can be moved upward from the middle groove 22 and embedded into the card groove 21, and then the abutment plate 4 is closed so that the upper end of the abutment plate 4 is supported under the roller shaft 31, thereby completing the loading and unloading of the roller 3.

[0019] Furthermore, a handle 5 is provided on the outer side of the abutment plate 4, for the operator to open and close the abutment plate 4 by means of the handle 5. A stepped groove 23 is provided on the outer periphery of the middle groove 22, and the free end of the abutment plate 4 is fixed to the stepped groove 23 by means of bolts. This prevents the abutment plate 4 from loosening and rotating open due to vibration of the conveyor, thereby improving the stability of the abutment plate 4 in the closed state.

[0020] The free end of the abutment plate 4 is provided with a rounded structure to enable the abutment plate 4 to be smoothly opened and closed. When closing the abutment plate 4, it can slide along the rounded corner to abut under the roller shaft 31 to support the roller 3.

[0021] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
