Description

Technical Field

[0001] This utility model relates to the field of tobacco technology, specifically to a disassembly device for belt conveyor idler shafts and bearings. Background Technology

[0002] In the vast system of belt conveyors, idlers are undoubtedly the most critical and numerous important components. They are like the solid "backbone" of the conveyor belt, shouldering the heavy responsibility of supporting the conveyor belt and bearing the weight of the materials. By reducing the resistance during belt operation, they ensure that the belt can run smoothly and steadily.

[0003] A complete idler roller set is mainly composed of two embedded bearings, an idler roller shaft, and a cylinder. Here, according to the specific standard of installation position, the bearings installed in the holes are uniformly named embedded bearings.

[0004] During daily production and operation, these two sets of embedded bearings are subjected to high-intensity working conditions and frequent forces, making them prone to wear. Once the wear reaches a certain level, they need to be disassembled and replaced in a timely manner to ensure the normal operation of the belt conveyor.

[0005] However, the disassembly of the bearings for this set of idler rollers currently faces many thorny issues. Because the bearings employ an embedded design, the common disassembly method requires two maintenance personnel working together: one uses a hammer, and the other holds a copper rod, attempting to remove the idler roller shaft by tapping the shaft end. After successfully removing the idler roller shaft, further steps are needed: a long tube is carefully inserted into the cylinder, precisely aligned with the bearing on the other side of the cylinder, and then knocked out again by tapping.

[0006] In practice, maintenance personnel have found numerous drawbacks to traditional disassembly methods when disassembling idler rollers that have reached their replacement cycle or are severely worn and must be replaced. First, the entire disassembly process is extremely time-consuming, significantly impacting equipment maintenance efficiency and potentially negatively affecting production schedules. Second, during the hammering process, the difficulty in precisely controlling the force and angle easily damages the threads of bearings and shaft end screws, and can even cause the shaft to bend and deform. This damage not only increases the cost of replacing spare parts but also further complicates equipment maintenance, contradicting the lean manufacturing principles of high efficiency, low cost, and high quality. Utility Model Content

[0007] In order to solve the above-mentioned problems, this utility model designs a disassembly device for belt conveyor idler shafts and bearings.

[0008] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0009] A belt conveyor idler roller shaft and bearing disassembly device includes a base plate. A support seat is provided on the left side of the top wall of the base plate. A cylinder is provided on the top wall of the support seat. A sliding groove is opened on the inner wall of the cylinder. A motor is provided on the left side wall of the cylinder. A lead screw is locked to the output end of the motor through a coupling. The outer wall of the lead screw extends into the cylinder and is threadedly connected to a connecting seat. A slider is provided on the outer wall of the connecting seat and is slidably connected in the sliding groove. A support rod is provided on the right side wall of the connecting seat. The right end of the support rod extends out of the cylinder and is provided with a locking mechanism.

[0010] A fixing mechanism is provided on the right side of the top wall of the base plate.

[0011] Furthermore, the locking mechanism includes a socket, in which a spring is embedded, and spring seats are provided at both the upper and lower ends of the spring. A locking block is provided on the outer side wall of the spring seat, and the outer end of the locking block extends out of the socket. A top block is provided on the right side wall of the socket.

[0012] Furthermore, the right side wall of the card block is designed as an inclined slope.

[0013] Furthermore, the fixing mechanism includes a support plate, a base is provided in the middle of the top wall of the support plate, support columns are provided on both the front and rear sides of the top wall of the support plate, a top plate is provided between the top walls of the support columns, a hydraulic cylinder is provided on the top wall of the top plate, a top seat is provided on the driving bottom wall of the hydraulic cylinder, a connecting plate is provided on the outer wall of the top seat, and a slider is provided on the outer end wall of the connecting plate, and the slider is slidably connected to the outer wall of the support column.

[0014] Furthermore, both the upper end face of the base and the lower end face of the top seat are provided with arc-shaped grooves.

[0015] Furthermore, the outer wall of the lead screw is rotatably connected to the inner wall of the cylinder via a bearing.

[0017] The beneficial effects of this utility model are:

[0018] This utility model, through an automated operation process, utilizes hydraulic cylinders and motors to drive related components, enabling the rapid and orderly disassembly of the idler roller shaft and embedded bearings. From fixing the idler roller body to sequentially disassembling the embedded bearings and idler roller shafts on both sides, the entire process is seamless and efficient, greatly shortening maintenance time, improving equipment maintenance efficiency, reducing the impact on production progress, and allowing the belt conveyor to resume normal operation more quickly.

[0019] This utility model adopts a hydraulic and mechanical linkage method. Through the coordinated action of components such as the top block and the locking block, the idler roller shaft and the embedded bearing are pushed and pulled in a stable and gradual manner. This avoids the damage to the equipment caused by the impact force generated by knocking, effectively reduces the risk of damage to the bearing and shaft head screw threads and shaft bending deformation, and extends the service life of the idler roller and related components.

[0020] The operation process of this utility model is relatively simple. Maintenance personnel only need to follow the set steps to start the hydraulic cylinder and motor, and the equipment can automatically complete the corresponding disassembly actions, which reduces the labor intensity and technical difficulty of the operators. Compared with traditional hammering operations, this utility model avoids the accidental injury that may be caused by hammering, improves the safety of maintenance work, and creates a safer working environment for maintenance personnel.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figure 1-3 As shown, a belt conveyor idler roller shaft and bearing disassembly device includes a base plate 1, a support seat 2 on the left side of the top wall of the base plate 1, a cylinder 3 on the top wall of the support seat 2, a groove 4 on the inner wall of the cylinder 3, a motor 5 on the left side wall of the cylinder 3, a lead screw 6 locked to the output end of the motor 5 through a coupling, the outer wall of the lead screw 6 extending into the cylinder 3, and a connecting seat 7 threadedly connected to the outer wall, a slider 8 on the outer wall of the connecting seat 7, and the slider 8 slidably connected in the groove 4, a support rod 9 on the right side wall of the connecting seat 7, the right end of the support rod 9 extending out of the cylinder 3, and a locking mechanism.

[0029] A fixing mechanism is provided on the right side of the top wall of the base plate 1.

[0030] In this application, the locking mechanism includes a socket 18, with a spring 19 embedded inside the socket 18. Both the upper and lower ends of the spring 19 are provided with spring seats 20. A locking block 21 is provided on the outer wall of the spring seat 20, and the outer end of the locking block 21 extends out of the socket 18. A top block 22 is provided on the right side wall of the socket 18. The reverse start motor 5 causes the connecting seat 7 to pull the support rod 9, the socket 18, and the locking block 21 to the left. The locking block 21 contacts the outer wall of the embedded bearing and pulls the embedded bearing to the left, thus pulling the left embedded bearing out of the roller cylinder.

[0031] In this application, the right side wall of the locking block 21 is designed as an inclined slope. The inclined wall of the locking block 21 contacts the embedded bearing on the left side of the roller cylinder, compressing the locking block 21 into the socket 18, so that the socket 18 can be easily inserted into the roller cylinder from the left end of the embedded bearing.

[0032] In this application, the fixing mechanism includes a support plate 10, a base 11 is provided in the middle of the top wall of the support plate 10, support columns 12 are provided on both the front and rear sides of the top wall of the support plate 10, a top plate 13 is provided between the top walls of the support columns 12, a hydraulic cylinder 14 is provided on the top wall of the top plate 13, a top seat 15 is provided on the driving bottom wall of the hydraulic cylinder 14, a connecting plate 16 is provided on the outer wall of the top seat 15, a slider 17 is provided on the outer end wall of the connecting plate 16, and the slider 17 is slidably connected to the outer wall of the support column 12. When the roller body is placed on the base 11, the top seat 15 is driven by the hydraulic cylinder 14 to move the connecting plate 16 and the slider 17 downward. The top seat 15 presses against the outer wall of the roller body, fixing the roller body on the base 11.

[0033] In this application, arc-shaped grooves are provided on the upper end surface of the base 11 and the lower end surface of the top seat 15, so that they fit more closely to the outer wall of the roller cylinder and improve the stability of the fixation.

[0034] In this application, the outer wall of the lead screw 6 is rotatably connected to the inner wall of the cylinder 3 through a bearing. The bearing fixes the lead screw 6 and facilitates its rotation.

[0035] In this application, the support rod 9 is a hollow structure, and the outer wall of the lead screw 6 is placed inside the support rod 9. Placing the outer wall of the lead screw 6 inside the support rod 9 effectively reduces the overall length of the lead screw 6 and the support rod 9.

[0036] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0037] One specific application of this embodiment is:

[0038] In use, the roller body is placed on the base 11, and the top seat 15 is driven by the hydraulic cylinder 14 to move the connecting plate 16 and the slider 17 downward. The top seat 15 presses against the outer wall of the roller body to fix the roller body on the base 11.

[0039] After the motor 5 is started, the lead screw 6 is rotated. The lead screw 6 causes the connecting seat 7 to move the support rod 9, socket 18, locking block 21, and top block 22 to the right. The top block 22 first contacts the left end of the idler shaft in the idler cylinder and pushes the idler shaft to the right. While the idler shaft moves to the right in the idler cylinder, the locking block 21 contacts the embedded bearing on the left side of the idler cylinder and compresses the locking block 21 into the socket 18 until the socket 18 enters the idler cylinder from the left end of the embedded bearing. At this time, the idler shaft is pushed out from the embedded bearing on the left side. The locking block 21 is reset by the elastic force of the spring 19, and the motor 5 is started in reverse. The connecting seat 7 pulls the support rod 9, socket 18, and locking block 21 to the left. The locking block 21 contacts the outer wall of the embedded bearing and pulls the embedded bearing to the left, pulling the embedded bearing on the left side out of the idler cylinder, completing the disassembly of the embedded bearing on the left side. The embedded bearing is then removed from the outer wall of the support rod 9.

[0040] The top seat 15 is driven by the hydraulic cylinder 14 to disengage from the roller body, and the right end of the roller body is rotated and moved to the left. The top seat 15 is driven by the hydraulic cylinder 14 to move downward to fix the roller body. The above operation is repeated. First, the roller shaft is pushed out from the embedded bearing and the embedded bearing is disassembled. After the second embedded bearing is taken out from the roller body, it is removed from the outer wall of the support rod 9. The roller shaft is then taken out from the roller body, and the disassembly of the embedded bearing and the roller shaft is completed.

[0041] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
