Description

Technical Field

[0001] This utility model relates to the field of coupling removal technology, and in particular to a coupling removal device. Background Technology

[0002] A coupling is a mechanical transmission device used to connect two shafts or rotating elements on shafts; its main function is to transmit rotational motion from one shaft to another, while allowing for a certain degree of deviation and misalignment. In coal mine electromechanical equipment, couplings are basically used to connect the motor and the reducer.

[0003] After a period of use, coal mine electromechanical equipment requires maintenance and repair. This includes replacing motor bearings and gearbox oil seals. This necessitates disassembling the coupling. The coupling's connection to the motor or gearbox is typically a clearance fit. However, after a period of use underground in a coal mine, mechanical stress, plastic deformation, compression, and damage can make the coupling difficult to disassemble.

[0004] In existing technologies, when disassembling the coupling body and shaft, the drive mechanism mostly uses an emulsion pump in conjunction with a hydraulic jack. A frame is welded to secure the jack, and the high pressure generated by the emulsion pump drives the extension or retraction of the jack's cylinder to disassemble the coupling. However, this method is heavily constrained by equipment and site conditions. It requires an emulsion pump at the work site, and the connecting pipeline from the emulsion pump to the jack's cylinder is very long. Furthermore, the coupling is easily ejected by the pressure of the emulsion pump, which is not only dangerous but also lacks stability.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to solve the problem of unstable disassembly of the coupling body.

[0007] This utility model solves the above-mentioned technical problems through the following technical means:

[0008] This utility model claims a coupling removal device, including a mounting frame, a drive mechanism, a fixing mechanism, and a second adjustment component. The mounting frame is provided with the drive mechanism, and the fixed part of the drive mechanism is provided with the fixing mechanism. The second adjustment component is configured to adjust the fixing mechanism to generate a constraint force on the coupling body, so as to restrict the coupling body from moving away from the drive mechanism.

[0009] It also includes an alignment mechanism, which is provided on the mounting bracket. The alignment mechanism is configured to adjust the output end of the drive mechanism to align with the shaft. The output end of the drive mechanism is configured to provide driving force to the shaft. The drive shaft moves axially relative to the coupling body, and the driving force and the constraint force are in opposite directions.

[0010] Preferably, the fixing mechanism includes at least two fixing arms, with a gap reserved between the lower fixing arms for the shaft to pass through vertically; the fixing arms have an inverted L-shaped cross-section configuration, the fixing part of the drive mechanism is connected to one end of the fixing arm, and the other end of the fixing arm extends toward the output part of the drive mechanism to form a locking end.

[0011] Preferably, the fixed arm includes a longitudinal arm, a crossbar, and a locking block.

The longitudinal arm and the axis of the drive mechanism fixing part are perpendicular to each other. The other end of the longitudinal arm is provided with a crossbar through a second adjustment component to form an inverted L-shaped cross section. A locking block is provided at the end of the crossbar away from the longitudinal arm. The locking block is perpendicular to the crossbar, wherein the locking block constitutes a locking end.

[0012] Preferably, the longitudinal arm passes through the through hole, which extends along the length of the longitudinal arm. A thread is provided at one end of the crossbar away from the locking block to form a threaded section. The threaded section passes through the through hole, and the crossbar slides in the through hole until the crossbar body is in contact with the outer wall of the coupling body. The thread engages with the locking nut until the locking nut is tightly fitted against one side of the longitudinal arm, and the locking block is tightly fitted against the end of the coupling body. The through hole, the thread, and the locking nut together constitute the second adjustment component.

[0013] Preferably, the alignment mechanism includes a third adjustment component, the mounting frame includes a vertical frame, the vertical frame has an inverted U-shaped frame structure, one end of the third adjustment component is provided at the top of the vertical frame, and a drive mechanism is installed at the other end of the third adjustment component, wherein the third adjustment component is configured to adjust the drive mechanism to move in the vertical direction.

[0014] Preferably, the third adjustment component includes a linear adjustment component and a sliding component. The sliding component is installed inside the vertical frame and is fixed by a fixing mechanism. The linear adjustment component is installed at the crossbeam of the vertical frame and is configured to drive the sliding component to move vertically within the vertical frame.

[0015] Preferably, the sliding assembly includes a sliding plate, a slider, and a sliding groove. Sliding grooves are formed on both sides of the inner wall of the vertical frame along the vertical direction. Mounting holes are formed on the surface of the sliding plate, and a drive mechanism fixing part is installed in the mounting holes. Sliders are provided on both sides of the sliding plate, and the sliders respectively form a sliding guide engagement with the sliding grooves.

[0016] Preferably, the drive mechanism includes a puller body, an oil inlet pipe, an oil return pipe, an oil tank, a reversing valve, and a motor. The mounting frame includes a base plate, on which a vertical frame is mounted to form a U-shaped structure. The puller body is coaxially mounted in the mounting hole. The puller body housing constitutes the fixed part of the drive mechanism, and the puller body telescopic column constitutes the output part of the drive mechanism. An oil tank is set on the side of the base plate away from the puller body telescopic column. A motor is set on the oil tank, and the motor is connected to the oil pump in the oil tank. The oil tank is connected to the reversing valve, and the oil outlet of the reversing valve is connected to the puller body through the oil inlet pipe and the oil return pipe, respectively.

[0017] Preferably, the linear adjustment assembly includes a lead screw and an adjuster, a vertical frame beam passes through the lead screw hole, the axis of the lead screw hole is vertical, the lead screw is engaged in the lead screw hole, the top of the lead screw is connected to the adjuster, and the bottom of the lead screw is connected to the slide plate.

[0018] Preferably, the alignment mechanism further includes a first adjustment component, which is installed at the bottom of the base plate and is configured to adjust the mounting bracket to move horizontally.

[0019] The advantages of this utility model are:

[0020] I. This utility model claims a coupling removal device. A second adjusting component adjusts the fixing mechanism to generate a constraint force on the coupling body. This, combined with an alignment mechanism, aligns the output end of the drive mechanism with the shaft. The drive mechanism output provides a driving force to the shaft, with the driving force and constraint force in opposite directions. Ultimately, this causes the shaft and coupling body to slide relative to each other axially, resulting in separation. Because the driving force and constraint force are in opposite directions, regardless of how the drive mechanism pushes the shaft, the force is essentially located at the center of the coupling body, keeping the coupling body stable. Furthermore, the relative motion trend of the coupling body is always opposite to that of the shaft. After removal, the coupling body is always constrained by the fixing mechanism and will not suddenly lurch out. This not only increases the safety and efficiency of removal but also improves the overall stability.

[0021] Second, the fixing mechanism is set with at least two fixing arms, and the inverted L-shaped structure of the fixing arms allows the fixing arms and the drive mechanism to enclose a space for accommodating the coupling body. Moreover, based on actual working conditions, a gap is reserved between the lower fixing arms to allow the shaft to pass through vertically. In this way, when the third adjustment component moves the fixing arms downward, the shaft and the coupling body will not obstruct the movement of the fixing arms.

[0022] 3. In actual use, the locking block can be installed at the crossbar by means of a pin or by welding. When welded, the locking block and the crossbar are integrated, thereby improving the stability of the locking block. Of course, since the locking block is squeezed by the coupling body during the entire disassembly process, the concentrated force can easily lead to damage to the locking block. Therefore, depending on the actual situation, the locking block and the crossbar can also be fixed by inserting a pin along the radial direction of the crossbar.

[0023] Fourth, the second adjustment component has two steps in use. First, the crossbar moves within the through hole, causing the crossbar to fit against the outer wall of the coupling body, thus restricting the radial movement of the coupling body. Then, the locking nut engages with the thread, causing the locking block to abut against the end of the coupling body, thus restricting the axial movement of the coupling body. This allows for quick fixing in two directions with a single component, which is not only simple in structure but also easy for personnel to adjust.

[0024] V. In general, the alignment mechanism includes a third adjustment component and a first adjustment component. The third adjustment component is set on the vertical frame and is used to adjust the drive mechanism to move in the vertical direction, while the first adjustment component is installed on the base plate and moves in the horizontal direction through the base plate mounting bracket. This means that the first adjustment component can adjust the drive mechanism to move in the horizontal direction, thereby achieving full alignment between the output end of the drive mechanism and the shaft.

[0025] VI. The third adjustment component, by setting a sliding component, can both guide the movement of the fixed part of the fixed mechanism and support the fixed part of the fixed mechanism, so that the fixed part of the fixed mechanism always moves vertically when driven by the third adjustment component. This not only avoids slippage of the fixed part of the fixed mechanism, but also ensures the alignment accuracy between the output part of the drive mechanism and the shaft in the later stage.

[0026] 7. By setting sliders on both sides of the skateboard, and then cooperating with the sliders in the sliding grooves on the inner wall of the vertical frame, the guiding function of the skateboard is realized. Combined with the special shape of the vertical frame of this application, the skateboard and the vertical frame always form a whole surface, which improves the overall stability.

[0027] 8. By setting up a puller body, motor and oil tank, the existing jack and emulsifying pump are replaced, which not only reduces the space required for use, but also reduces the weight. Combined with the first adjustment component 51, the whole is lighter and more convenient. Moreover, this utility model also abandons the violent disassembly method of directly hitting the coupling body in the existing technology. By using the reversing valve in conjunction with the opening and closing of the puller body, the shaft is pushed. With the constraint of the locking end, the driving force is not only stable and uniform, but also concentrated. The coupling body is less damaged after disassembly and will not fly out due to hitting, which is safe and reliable.

[0028] 9. The linear adjustment component can be implemented using any linear drive device available on the market, with lead screw adjustment being preferred. Considering that the alignment accuracy between the output part of the drive mechanism and the shaft directly affects the disassembly of the coupling, the high precision of lead screw adjustment is more in line with the requirements.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0037] See Figure 1 and Figure 2This utility model claims a coupling removal device, including a mounting frame, a drive mechanism, a fixing mechanism, an alignment mechanism, and a second adjustment component. The mounting frame is equipped with the drive mechanism, and the drive mechanism fixing part is equipped with the fixing mechanism. The second adjustment component is configured to adjust the fixing mechanism to exert a constraint force on the coupling body, thereby restricting the coupling body from moving away from the drive mechanism. The fixing mechanism includes at least two fixing arms 30, with a gap reserved between the lower fixing arms 30 for the shaft to pass through vertically. The fixing arms 30 have an inverted L-shaped cross-section. The drive mechanism fixing part is connected to one end of the fixing arm 30, and the other end of the fixing arm 30 extends towards the drive mechanism output part. The locking end, the fixed arm 30, includes a longitudinal arm 301, a crossbar 302, and a locking block 303. The drive mechanism fixing part connects to one end of the longitudinal arm 301 to form a connecting end. The axes of the longitudinal arm 301 and the drive mechanism fixing part are perpendicular to each other. The other end of the longitudinal arm 301 is connected to the crossbar 302 via a second adjusting component, forming an inverted L-shaped cross-section. The longitudinal arm 301 passes through a through hole 40, which extends along the length of the longitudinal arm 301. A thread 41 is provided at one end of the crossbar 302 away from the locking block 303, forming a threaded segment 41. This threaded segment passes through the through hole 40. The crossbar 302 slides within the through hole 40 until its body is in contact with the outer wall of the coupling body. The thread 41 engages with the locking nut 42. The locking nut 42 abuts against one side of the longitudinal arm 301, and the locking block 303 abuts against the end of the coupling body. The through hole 40, the thread 41, and the locking nut 42 together constitute the second adjustment assembly. The second adjustment assembly is used in two steps: First, the crossbar 302 moves within the through hole 40, causing the crossbar 302 to fit against the outer wall of the coupling body, thus restricting the radial movement of the coupling body. Then, the locking nut 42 engages with the thread 41, causing the locking block 303 to abut against the end of the coupling body, thus restricting the axial movement of the coupling body. This single component achieves rapid fixing in two directions, resulting in a simple structure. Furthermore, to facilitate personnel adjustment, a locking block 303 is provided at the end of the crossbar 302 away from the longitudinal arm 301. The locking block 303 is perpendicular to the crossbar 302. The locking block 303 constitutes a locking end. In actual use, the locking block 303 can be installed at the crossbar 302 by means of a pin or by welding. When welded, the locking block 303 and the crossbar 302 are integrated, thereby improving the stability of the locking block 303. Of course, since the locking block 303 is squeezed by the coupling body during the entire disassembly process, the concentrated force can easily lead to damage to the locking block 303. Therefore, depending on the actual situation, the locking block 303 and the crossbar 302 can also be fixed by inserting a pin along the radial direction of the crossbar 302.

[0038] The mounting bracket is equipped with an alignment mechanism, which is configured to align the output end of the adjustment drive mechanism with the shaft. The alignment mechanism includes a first adjustment component 51 and a third adjustment component. The mounting bracket includes a base plate 11 and a vertical frame 10. The vertical frame 10 is mounted on the base plate 11 to form a U-shaped structure. The first adjustment component 51 is mounted at the bottom of the base plate 11 and is configured to adjust the horizontal movement of the mounting bracket. The vertical frame 10 has an inverted U-shaped structure. One end of the third adjustment component is located at the top of the vertical frame 10, and the other end of the third adjustment component is equipped with a drive mechanism. The third adjustment component is configured to adjust... The drive mechanism moves vertically. The third adjustment component is mounted on the vertical frame 10 to adjust the vertical movement of the drive mechanism. The first adjustment component 51 is mounted on the base plate and moves horizontally via the base plate mounting bracket. This means that the first adjustment component 51 can adjust the horizontal movement of the drive mechanism, thereby achieving full alignment between the output end of the drive mechanism and the shaft. The third adjustment component includes a linear adjustment component 501 and a sliding component 502. The sliding component 502 is installed inside the vertical frame 10, and the sliding component 502 is fitted with a fixing part of the fixing mechanism. The 02 includes a sliding plate 5020, a slider 5021, and a groove 5022. Grooves 5022 are vertically formed on both sides of the inner wall of the vertical frame 10. Mounting holes are formed on the surface of the sliding plate 5020, and a drive mechanism fixing part is installed in the mounting holes. Slider 5021 is provided on both sides of the sliding plate 5020, and the slider 5021 respectively forms a sliding guide engagement with the groove 5022. A linear adjustment component 501 is provided at the crossbeam of the vertical frame 10. The linear adjustment component 501 is configured to drive the sliding component 502 to move vertically within the vertical frame 10. The linear adjustment component 501 includes a lead screw 5010 and an adjustment... The regulator 5011, the crossbeam of the vertical frame 10 passes through the lead screw hole, the axis of the lead screw hole is vertical, the lead screw 5010 is engaged in the lead screw hole, the top of the lead screw 5010 is connected to the adjuster 5011, and the bottom of the lead screw 5010 is connected to the slide plate 5020 to form a transition fit. By setting sliders 5021 on both sides of the slide plate 5020, and cooperating with the sliders 5021 sliding with the slide grooves 5022 on the inner wall of the vertical frame 10, the guiding function of the slide plate 5020 is realized. Combined with the special shape of the vertical frame 10 in this application, the slide plate 5020 and the vertical frame 10 always form a whole surface, which improves the overall stability.

[0039] The output section of the drive mechanism is configured to provide driving force to the shaft, which moves axially relative to the coupling body, with the driving force and constraint force in opposite directions. The drive mechanism includes a puller body, an oil inlet pipe 21, an oil return pipe 22, an oil tank 23, a reversing valve 24, and a motor 25. The puller body is coaxially mounted in the mounting hole. The puller body housing constitutes the fixed part of the drive mechanism, and the puller body telescopic column constitutes the output section of the drive mechanism. An oil tank 23 is located on the side of the base plate 11 away from the puller body telescopic column. The motor 25 is mounted on the oil tank 23 and connected to the oil pump inside the oil tank 23. The oil tank 23 is connected to the reversing valve 24, and the oil outlet of the reversing valve 24... The puller body is connected to the oil inlet pipe 21 and the oil return pipe 22 respectively. By setting up the puller body, motor 25 and oil tank 23, the jack and emulsifying pump of the prior art are replaced. This not only reduces the space required for use, but also reduces the weight. With the first adjustment component 5151, the whole is lighter and more convenient. Moreover, this utility model also abandons the violent disassembly method of directly hitting the coupling body in the prior art. By using the reversing valve 24 in conjunction with the opening and closing of the puller body, the shaft is pushed. With the constraint of the locking end, the driving force is not only stable and uniform, but also concentrated. The coupling body is less damaged after disassembly and will not fly out due to hitting. It is safe and reliable.

[0040] Based on this, a specific application scenario for the coupling removal device is provided, wherein the lead screw 5010 is preferably 1.2 meters in total length. The adjuster 5011 is preferably an eight-claw structure, mainly for ease of handheld operation. The puller body 20 is preferably a working stroke of 200 mm and a working pressure of 40 MPa, which is existing technology and will not be described further.

[0041] Preferably, there are three fixed arms 30, the main body of which is preferably made of round steel, and the three fixed arms 30 are preferably arranged in a ring array around the fixed part of the drive mechanism. The telescopic column of the puller body 20 preferably has a stroke of 200 mm. This is a structure that is inherent to the puller body 20 itself and is existing technology, so it will not be described in detail.

[0042] The first adjusting component 51 is preferably a roller with a locking function. The oil tank 23 is a tank for holding hydraulic oil, preferably with a filler hole at the top and a drain hole at the bottom. The reversing valve 24 is preferably a manual reversing valve, and the manual reversing valve is equipped with an operating handle. The operating handle controls the flow direction of the hydraulic oil and operates the extension and retraction function of the telescopic column of the puller body 20. The motor 25 is preferably an explosion-proof motor, which can generate a high-voltage power source, preferably with a voltage of 380V and a power of 3.5KW. The motor 25 extends into the oil tank and connects to the oil pump. Depending on the actual situation, a handle 12 can also be provided on the vertical frame 10. The handle 12 is preferably formed by pressurizing steel pipe, which is convenient for personnel to hold and push the mounting frame.

[0043] This utility model claims a coupling removal device. A second adjusting component adjusts the fixing mechanism to generate a constraint force on the coupling body. This, combined with an alignment mechanism, aligns the output end of the drive mechanism with the shaft. The drive mechanism output provides a driving force to the shaft, with the driving force and constraint force in opposite directions. Ultimately, this causes the shaft and coupling body to slide relative to each other axially, resulting in separation. Because the driving force and constraint force are in opposite directions, regardless of how the drive mechanism pushes the shaft, the force is essentially located at the center of the coupling body, keeping the coupling body stable. Furthermore, the relative motion trend of the coupling body is always opposite to that of the shaft. After removal, the coupling body is always constrained by the fixing mechanism and will not suddenly lurch out. This not only increases the safety and efficiency of removal but also improves overall stability.

[0044] Based on this, a specific application scenario for the coupling removal device is further provided. The first adjustment component 51 is adjusted so that the fixing mechanism is located directly above the coupling body. Specifically, the motor with the coupling body is placed on a flat ground, and the handle 12 is pushed so that the fixing mechanism is located directly above the coupling body. At this time, care should be taken not to lock the first adjustment component 51.

[0045] First, by rotating the adjuster 5011, the lead screw 5010 is rotated and engages with the lead screw hole of the crossbeam of the vertical frame 10, which drives the puller body to move up and down. After aligning the center of the puller body 20 telescopic column center coupling body with the center, the adjuster 5011 is stopped.

[0046] Then, by moving the crossbar 302 within the through hole 40, the body of the crossbar 302 is brought into contact with the outer wall of the coupling body, thus restricting the radial movement of the coupling body. In addition, the locking nut 42 engages with the thread 41, so that the locking block 303 is pressed against the end of the coupling body, thus restricting the axial movement of the coupling body.

[0047] Finally, connect the power cord of motor 25. Motor 25 drives the oil pump in oil tank 23 to rotate, generating high pressure. When it is necessary to remove the coupling body, turn the operating handle. Hydraulic oil enters the puller body 20 through the oil inlet pipe 21, causing the telescopic column of the puller body 20 to extend, pushing the shaft to move axially. Due to the abutment and engagement of the locking block 303 with the end of the coupling body, the coupling body is removed. After the coupling body is removed, turn the operating handle in the opposite direction. The method of using a drive mechanism to move the telescopic column of the puller body 20 is existing technology and will not be described in detail.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
