[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Example 1: Reference Figures 1 to 5This application provides a crusher hammer replacement device, including a bracket 1. The bracket 1 includes a support leg 11 and a support frame 12. The support frame 12 is disposed above the support leg 11 and fixedly connected to the support leg 11. It also includes a moving mechanism 2, which is disposed on the support frame 12 and can move along the support frame 12 in the lateral direction. Figure 1 (as shown in the X direction) or longitudinal direction ( Figure 1 (As shown in the Z direction) moves; the replacement mechanism 3, connected to the moving mechanism 2 and located below the moving mechanism 2, includes a drive assembly 31 connected to the moving mechanism 2 and a replacement part 32 connected to the drive assembly 31. The drive assembly 31 is used to drive the replacement part 32 in the vertical direction (as shown in the Z direction); ... Figure 1 (As shown in the Y direction) it moves toward the crusher hammer, and the replacement unit 32 is used to connect with the crusher hammer to remove the crusher hammer from the crusher.

[0026] In this embodiment, the support leg 11 is made of metal and has a columnar structure, used to support the entire device and the forces it bears during hammer replacement. Its bottom is typically equipped with a shock-absorbing and anti-slip pad, which reduces the impact of vibrations generated during the operation of the moving mechanism 2 and the replacement mechanism 3 on the ground and the stability of the moving mechanism 2 and the replacement mechanism 3 themselves. It also increases friction with the ground, preventing accidental sliding or displacement of the moving mechanism 2 and the replacement mechanism 3 during operation.

[0027] The support frame 12 is made of metal and is assembled into a frame structure by welding, which has rigidity and stability. At the connection point with the support leg 11, it is fixed with bolts to make the connection between the support frame 12 and the support leg 11 firm and reliable, and able to withstand various forces transmitted by the moving mechanism 2 and the changing mechanism 3 during operation.

[0028] The replacement mechanism 3 includes a drive assembly 31 and a replacement part 32. The drive assembly 31 is installed below the moving mechanism 2, and the replacement part 32 is connected to the drive assembly 31. When replacing the crusher hammer, the moving mechanism 2 drives the drive assembly 31 to move directly above the crusher hammer to be replaced; the drive assembly 31 starts, driving the replacement part 32 to descend vertically until the replacement part 32 is aligned with the hammer; the replacement part 32 is connected and fixed to the crusher hammer, and the drive assembly 31 drives the replacement part 32 to rise, removing the crusher hammer from the crusher; the moving mechanism 2 drives the replacement mechanism 3 and the grasped crusher hammer to the storage area, the drive assembly 31 descends, and the replacement part 32 releases, completing the replacement of the crusher hammer; the above steps are reversed to complete the installation of a new crusher hammer.

[0029] By adopting the above technical solution, the support bracket provides stable support during the movement and replacement of the crusher hammers, ensuring the safety of the operation. The moving mechanism 2 enables the replacement mechanism 3 to quickly and accurately align with the crusher hammers, eliminating the need for repeated manual adjustments and reducing positioning time. The replacement mechanism 3 replaces the crusher hammers, and the drive component 31 provides power to the replacement part 32, achieving mechanized operation of the replacement process. This avoids the heavy labor of manually handling and disassembling the hammers, significantly reducing manpower consumption and improving the overall efficiency of hammer replacement.

[0030] Example 2: Reference Figures 3 to 4 In one feasible embodiment, the drive assembly 31 includes a drive motor and a drum 311 driven to rotate by the drive motor, on which a cable 312 is wound and passes over a movable pulley 313. The starting end of the cable 312 is fixed to the drum 311, and its free end is led out from the drum 311, passes downward around the pulley groove of the movable pulley 313, and is then fixedly connected upward to a fixed point of the moving mechanism 2 or the bracket 1. When the drum 311 rotates to retract or release the cable 312, it drives the movable pulley 313 to move in the vertical direction.

[0031] In this embodiment, the drive motor needs to drive the entire weight of the replacement unit 32 and the hammer head. The drive motor adjusts the rotation of the drum 311 through the reducer so that the rotation speed of the drum 311 meets the requirements of the lifting speed of the movable pulley 313 during the hammer head replacement operation, and also ensures that the whole process is stable.

[0032] The drum 311 has a hollow structure, with hub structures at both ends to prevent it from loosening during rotation. The outer surface of the drum 311 is machined with spiral grooves to guide the cable 312 in an orderly winding and unwinding manner, preventing the cable 312 from becoming tangled or jumping around on the drum 311, and ensuring a tight fit between the cable 312 and the drum 311. The cable 312 is made of steel wire rope, with the steel wires being carbon structural steel, possessing tensile strength and flexibility.

[0033] The cable 312 is wound as follows: one end of the cable 312 is fixedly installed in the rope groove of the drum 311; after the cable 312 is led out from the drum 311, it extends vertically downward; then it passes under the pulley groove of the movable pulley 313; after passing under the movable pulley 313, the cable 312 extends vertically upward again, and its other end is fixedly connected to a fixed point on the moving mechanism 2 or the bracket 1. Figure 4 In the middle, the other end of the cable 312 is fixedly connected to the moving mechanism 2.

[0034] When the drive motor drives the drum 311 to rotate forward to take in the wire, the length of the cable 312 between the drum 311 and the fixed point is shortened, thereby pulling the movable pulley 313 and the replacement part 32 below it to move upward; when the drum 311 rotates in reverse to let out the wire, the movable pulley 313 and the replacement part 32 move downward under the action of gravity.

[0035] Example 3: Continue to refer to Figures 3 to 4 In one feasible embodiment, a mounting hole is provided at the center of the movable pulley 313, and a first bearing (not shown in the figure) is provided in the mounting hole. The inner ring of the first bearing is fixedly connected to a connecting shaft (not shown in the figure). The replacement part 32 includes two hook plates 321 and hooks 322. The heads of the two hook plates 321 are respectively connected to the two ends of the connecting shaft, and the heads of the hooks 322 are respectively connected to the tails of the two hook plates 321. The hooks 322 are capable of hooking the hammer of the crusher.

[0036] In this embodiment, a hook 322 is used to hook the hammer of the crusher to replace the hammer of the crusher. A mounting hole is provided at the center of the movable pulley 313. A first bearing is installed in the mounting hole. A connecting shaft is fixedly connected to the inner ring of the first bearing. The connecting shaft and the inner ring of the first bearing are interference fit so that the connecting shaft and the first bearing are installed and fixed.

[0037] The hook plate 321 is a plate structure. The hook plate 321 is fixedly connected to the connecting shaft by bolts. The hook 322 is usually hook-shaped. Its opening size is determined according to the size of the connection part of the crusher hammer to ensure that the hammer can be hooked smoothly and that there is sufficient contact area and clamping force after hooking to prevent the hammer from falling off.

[0038] Example 4: Reference Figure 5 In one feasible embodiment, the replacement unit 32 further includes: The first cylinder 323 has a hanging hole 3231 on its top. The first cylinder 323 is connected to the movable pulley 313 through a connector passing through the hanging hole 3231. The first cylinder 323 is vertically arranged in the vertical direction, and the drive shaft of the first cylinder 323 is arranged downward. The housing 324 is located vertically below the first cylinder 323. The housing 324 is a cavity structure with openings at both ends. A linkage mechanism 325 is provided inside the housing 324. The drive shaft of the first cylinder 323 extends into the housing 324 through the top opening and is connected to the linkage mechanism 325. The gripper 326 extends into the housing 324 through the bottom opening of the housing 324 and is connected to the linkage mechanism 325. The gripper 326 is rotatably mounted on the housing 324 via a rotating shaft. In this process, the drive shaft of the first cylinder 323 drives the linkage mechanism 325 to move, so that the gripper 326 opens and closes. The gripper 326 is used to grip the hammer of the crusher.

[0039] In this embodiment, if there is no crusher hammer that can be hooked, the crusher hammer can also be replaced by gripping it with the claw 326. The first cylinder 323 is a piston cylinder. For heavier and larger hammers, a cylinder with a larger cylinder diameter and a suitable stroke is selected to provide sufficient driving force to drive the linkage mechanism 325 and realize the opening and closing action of the claw 326.

[0040] The hanging hole 3231 on the top of the first cylinder 323 is circular or elliptical in shape. Its diameter is matched according to the size of the hook 322. The edges of the hanging hole 3231 are rounded to prevent the hook 322 from scratching or stress concentration when passing through the hanging hole 3231.

[0041] At the top opening of the housing 324, the first cylinder 323 is fixed to the housing 324 by bolts. At the bottom opening of the housing 324, the gripper 326 extends into the housing 324 from the bottom opening. At the same time, the edge of the bottom opening of the housing 324 is chamfered to avoid the gripper 326 from colliding or interfering with the edge of the housing 324 during the movement.

[0042] The linkage mechanism 325 is typically composed of multiple links and joints. The links are connected by pins. The linkage mechanism 325 is connected to the drive shaft of the first cylinder 323 through a connector. One end of the connector is connected to the drive shaft of the first cylinder 323, and the other end is connected to the link of the linkage mechanism 325 through a hinge. This allows the extension and retraction motion of the drive shaft of the first cylinder 323 to be transmitted to the linkage mechanism 325, thereby driving the entire mechanism to perform corresponding movements.

[0043] The linkage mechanism 325 can convert the vertical linear motion of the drive shaft of the first cylinder 323 into the opening and closing rotational motion of the gripper 326.

[0044] Specifically, when the first cylinder 323 drives the shaft to extend or retract, the linear motion is converted into the oscillation of the connecting rods of the linkage mechanism 325 through the hinge structure of the connector. Each connecting rod of the linkage mechanism 325 transmits this oscillation sequentially through the pin joints between the connecting rods, causing the entire linkage mechanism 325 to oscillate in unison, ultimately causing the gripper 326 connected at the end to open and close accordingly. The method by which the first cylinder 323 drives the linkage mechanism 325 to achieve the corresponding opening and closing of the gripper 326 adopts a driving method commonly used in the gripping mechanisms of industrial robotic arms in the prior art.

[0045] The shape and size of the jaws 326 are usually similar to fingers, with the ends designed as arc-shaped clamping surfaces. The arc-shaped clamping surfaces can better fit the outline of the hammer head. The main body of the jaws 326 is made of high manganese steel, which has toughness and wear resistance when subjected to large clamping forces and friction, and is not prone to deformation or wear.

[0046] Example 5: Continue to refer to Figures 1 to 2 In one feasible embodiment, along the lateral direction, the support frame 12 includes two parallel and spaced first slide rails 121 and second slide rails 122. The moving mechanism 2 includes a first moving component 21, a second moving component 22, and a first driving member 23. The first moving component 21 is slidably mounted on the first slide rail 121, and the second moving component 22 is slidably mounted on the second slide rail 122. The first driving member 23 is connected to the first moving component 21 and the second moving component 22 respectively, so as to drive the first moving component 21 and the second moving component 22 to move on the first slide rail 121 and the second slide rail 122 respectively.

[0047] In this embodiment, the first slide rail 121 and the second slide rail 122 are made of steel, and the cross-sectional shape is designed as an I-beam for easy installation and fixing.

[0048] The first moving component 21 is slidably mounted on the first slide rail 121, and the second moving component 22 is slidably mounted on the second slide rail 122. Both the first and second moving components 21 are driven by the first driving component 23, enabling synchronized movement and ensuring consistent displacement. When the crusher hammer needs to be replaced, the first driving component 23 is activated, synchronously transmitting power to the first and second moving components 21 and 22, causing them to move laterally at the same speed and in the same direction along the first and second slide rails 121 and 122 respectively. This achieves overall lateral position adjustment of the moving mechanism 2. Once the replacement mechanism 3 moves to the corresponding position of the crusher hammer, the driving component 31 of the replacement mechanism 3 drives the replacement part 32 to clamp, disassemble, and subsequently install the hammer, completing the task of replacing the crusher hammer.

[0049] By employing two parallel, spaced-apart double-slide rail structures, the moving mechanism 2 is provided with dual-sided support. Combined with the corresponding sliding installation of the first moving component 21 and the second moving component 22, the load is effectively distributed, preventing deformation or shaking caused by excessive force, resulting in smoother overall movement. This reduces the load-bearing pressure on individual components, decreases the probability of wear or failure due to long-term use, and extends the service life of the equipment.

[0050] Furthermore, the synergistic effect of the dual slide rails and dual moving components allows it to bear greater weight, thus expanding the applicability of the device.

[0051] Example 6: Continue to refer to Figure 1 and Figure 2 In one feasible embodiment, the first drive member 23 includes a drive shaft 231, and the first moving component 21 includes: The first drive wheel (not shown in the figure) is slidably mounted on the first slide rail 121. One end of the drive shaft 231 is connected to the first drive wheel and is used to drive the first drive wheel to roll on the first slide rail 121. The first dust cover 211 includes a cavity structure with a bottom opening. The first dust cover 211 covers the top of the first drive wheel. A second bearing is provided on the drive shaft 231. The first dust cover 211 abuts against the outer ring of the second bearing. The first drive wheel is located at one end of the first dust cover 211. The first driven wheel (not shown in the figure) is slidably mounted on the first slide rail 121. Its specifications match those of the first driving wheel. The first driven wheel is located at the other end of the first dust cover 211. A first driven shaft is provided at the center of the first driven wheel. A third bearing is provided on the first driven shaft. The outer ring of the third bearing abuts against the first dust cover 211.

[0052] In this embodiment, the wheel body of the first drive wheel is typically made of cast iron or cast steel. Its outer contour shape is adapted to the shape of the first slide rail 121. For example, when the first slide rail 121 is I-shaped, the outer surface of the first drive wheel will have corresponding grooves or protrusions to allow it to roll on the I-shaped first slide rail 121, ensuring stability during movement.

[0053] The first drive wheel and the drive shaft 231 are connected by a mechanical connection to transmit power. A keyway is machined on the hub of the first drive wheel, and a flat key is installed on the drive shaft 231 accordingly. By embedding the flat key into the keyway, the first drive wheel and the drive shaft 231 are tightly fitted together to achieve effective torque transmission.

[0054] Two second bearings are provided, with their inner rings fitted onto the drive shaft 231, and the two second bearings respectively located on both sides of the first drive wheel. The first dust cover 211 has a hollow structure with an open bottom. Its shape is customized according to the layout of the first drive wheel, drive shaft 231, and other components, completely covering the first drive wheel to provide dust protection. The first dust cover 211 can also be placed on the outer ring of the second bearings. The first dust cover 211 is made of thin steel plate and manufactured through a stamping process.

[0055] The edge of the first dust cover 211 abuts against the outer ring of the second bearing. Using the outer ring of the second bearing as a support point, it can not only ensure the stability of the installation of the first dust cover 211, but also further prevent dust from entering the critical area where the first drive wheel and drive shaft 231 are located from the gap between the second bearing and the surrounding components.

[0056] The specifications of the first driven wheel match those of the first driving wheel, and its wheel diameter is usually consistent with that of the first driving wheel to ensure that the two can rotate synchronously when moving on the first slide rail 121, maintaining the stability of the entire first moving assembly 21; ensuring that the contact area and force conditions are similar to those of the first slide rail 121, making the movement process more stable; the outer contour shape of the first driven wheel is adapted to the shape of the first slide rail 121, and can be smoothly slidably installed on the first slide rail 121, for example, it can slide on the I-shaped first slide rail 121 like the first driving wheel.

[0057] The installation method of the first driven wheel and the first slide rail 121 is similar to that of the first driving wheel. A first driven shaft is set at the center of the first driven wheel, and a third bearing is set on the first driven shaft. There are two third bearings. The inner ring of the third bearing is fitted onto the first driven shaft, and the two third bearings are respectively set on both sides of the first driven wheel. The outer ring of the third bearing abuts against the first dust cover 211. The first driven wheel plays an auxiliary support role and cooperates with the first driving wheel to ensure that the first moving component 21 moves smoothly on the first slide rail 121.

[0058] Example 7: Continue to refer to Figure 1 and Figure 2 In one implementable embodiment, the second moving component 22 includes: The second drive wheel (not shown in the figure) is slidably mounted on the second slide rail 122. The other end of the drive shaft 231 is connected to the second drive wheel and is used to drive the second drive wheel to roll on the second slide rail 122. The second dust cover 221 includes a cavity structure with a bottom opening. The second dust cover 221 covers the second drive wheel. A fourth bearing is provided on the drive shaft 231. The second dust cover 221 abuts against the outer ring of the fourth bearing. The second drive wheel is located at one end of the second dust cover 221. The second driven wheel (not shown in the figure) is slidably mounted on the second slide rail 122. Its specifications match those of the second driving wheel. The second driven wheel is located at the other end of the second dust cover 221. A second driven shaft is provided at the center of the second driven wheel. A fifth bearing is provided on the second driven shaft. The outer ring of the fifth bearing abuts against the second dust cover 221.

[0059] In this embodiment, the wheel body of the second drive wheel is typically made of cast iron or cast steel. Its outer contour shape is adapted to the shape of the second slide rail 122. For example, when the second slide rail 122 is I-shaped, the outer surface of the second drive wheel will have corresponding grooves or protrusions to allow it to roll on the I-shaped second slide rail 122, ensuring stability during movement.

[0060] The second drive wheel and the drive shaft 231 are connected by a mechanical connection to transmit power. A keyway is machined at the hub of the second drive wheel, and a flat key is installed on the drive shaft 231 accordingly. By embedding the flat key into the keyway, the second drive wheel and the drive shaft 231 are tightly fitted together to achieve effective torque transmission.

[0061] There are two fourth bearings. The inner ring of the fourth bearing is fitted on the drive shaft 231, and the two fourth bearings are respectively located on both sides of the second drive wheel.

[0062] The second dust cover 221 has a hollow structure with an open bottom. Its shape is customized according to the layout of components such as the second drive wheel and drive shaft 231. It completely covers the second drive wheel, performs the dustproof function, and can be mounted on the outer ring of the fourth bearing. The second dust cover 221 is made of thin steel plate and is manufactured by stamping.

[0063] The edge of the second dust cover 221 abuts against the outer ring of the fourth bearing. Using the outer ring of the fourth bearing as a support point, it can not only ensure the stability of the installation of the second dust cover 221, but also further prevent dust from entering the critical area where the second drive wheel and drive shaft 231 are located from the gap between the fourth bearing and the surrounding components.

[0064] The specifications of the second driven wheel match those of the second driving wheel, and its wheel diameter is usually consistent with that of the second driving wheel to ensure that the two can rotate synchronously when moving on the second slide rail 122, maintaining the stability of the entire second moving assembly 22; ensuring that the contact area and force conditions are similar to those of the second slide rail 122, making the movement process more stable; the outer contour shape is adapted to the shape of the second slide rail 122, so that it can be smoothly slidably installed on the second slide rail 122, for example, it can slide on the I-shaped second slide rail 122 in the same way as the second driving wheel.

[0065] The installation method of the second driven wheel and the second slide rail 122 is similar to that of the second driving wheel. A second driven shaft is set at the center of the second driven wheel, and a fifth bearing is set on the second driven shaft. There are two fifth bearings. The inner ring of the fifth bearing is fitted onto the second driven shaft, and the two fifth bearings are respectively set on both sides of the second driven wheel. The outer ring of the fifth bearing abuts against the second dust cover 221. The second driven wheel plays an auxiliary support role and cooperates with the second driving wheel to ensure that the second moving component 22 moves smoothly on the second slide rail 122.

[0066] Example 8: Continue to refer to Figure 1 and Figure 2 In one feasible embodiment, a ratchet 232 is provided on the drive shaft 231; the first drive member 23 also includes a first crossbeam 233, the two ends of the first crossbeam 233 are respectively connected to the top of the first dust cover 211 and the second dust cover 221, a first motor 234 is provided on the first crossbeam 233, a drive gear is provided on the first motor 234, and the drive gear is connected to the ratchet 232 through a chain to drive the drive shaft 231 to rotate.

[0067] In this embodiment, the ratchet 232 is installed in the middle of the drive shaft 231, and the teeth of the ratchet 232 are connected to the drive gear of the first motor 234 via a chain. The connection between the ratchet 232 and the drive shaft 231 adopts an interference fit to ensure that the ratchet 232 will not rotate relative to the drive shaft 231 or move axially. This ensures that when the first motor 234 drives the ratchet 232 to rotate via the drive gear, power can be transmitted to the drive shaft 231, thereby driving the first moving component 21 to move.

[0068] The first crossbeam 233 is a long strip structure used to support the first motor 234 and withstand various forces generated during movement. The first motor 234 is mounted on the first crossbeam 233, which has a motor mounting base. The motor mounting base is fixed to the first crossbeam 233 by bolts. The motor mounting base has mounting holes that match the first motor 234, and the first motor 234 is fixed to the motor mounting base by bolts.

[0069] The first dust cover 211 and the second dust cover 221 are both fixed to the first crossbeam 233 by bolts. Bolt holes are opened on the first dust cover 211, the second dust cover 221 and the first crossbeam 233 respectively, and bolts are used to connect them to prevent the first dust cover 211 and the second dust cover 221 from shaking or shifting due to vibration or other reasons during the movement of the device, so as to ensure that they always stably perform their dust protection function.

[0070] When the first motor 234 starts, the drive gear on the first motor 234 begins to rotate. The drive gear is connected to the ratchet 232 on the drive shaft 231 via a chain. The rotation of the drive gear drives the ratchet 232 to rotate, which in turn causes the drive shaft 231 to rotate. The rotation of the drive shaft 231 transmits torque to the first drive wheel and the second drive wheel via a key connection. The first drive wheel and the second drive wheel roll on the first slide rail 121 and the second slide rail 122, respectively. When the first drive wheel and the second drive wheel roll, the first drive wheel, relying on the friction between itself and the first slide rail 121 and its own rotation, drives the entire first moving assembly 21 to move along the first slide rail 121. The second bearing located on the drive shaft 231 supports the first dust cover 211, causing the first dust cover 211 to move with the first drive wheel. The first dust cover 211 performs a dustproof function, preventing external dust, impurities, etc., from entering the area where the first drive wheel and the drive shaft 231 are located, ensuring the normal operation of all components. The first driven wheel slides synchronously on the first slide rail 121 as the first moving component 21 moves as a whole, and together with the first driving wheel, it bears the supporting role of the entire first moving component 21 on the first slide rail 121, ensuring that the first moving component 21 is subjected to uniform force and runs smoothly during the movement. The second driving wheel is the same, and the first moving component 21 and the second moving component 22 move stably in the lateral direction.

[0071] Example 9: Continue to refer to Figure 2 In one feasible embodiment, a second crossbeam 24 is further provided on the top of the first dust cover 211 and the second dust cover 221, and a third moving component 25 is provided on the second crossbeam 24. The third moving component 25 is used to move along the longitudinal direction on the second crossbeam 24, wherein the replacement mechanism 3 is provided below the third moving component 25.

[0072] The second crossbeam 24 is provided with a guide rail, and the third moving assembly 25 includes: The drive wheel 252 is slidably mounted on the guide rail and can move along the longitudinal direction on the guide rail; The second motor 251 is vertically positioned below the guide rail. The second motor 251 is connected to the drive wheel 252 and is used to drive the drive wheel 252 to roll on the guide rail.

[0073] In this embodiment, the two ends of the second crossbeam 24 are connected to the first dust cover 211 and the second dust cover 221 respectively, so as to move in the lateral direction with the first dust cover 211 and the second dust cover 221. The replacement mechanism 3 is located below the third moving component 25. When replacing the crusher hammer, the replacement mechanism 3 first moves in the lateral direction with the second crossbeam 24 to the crusher hammer to be replaced, and then moves to the top of the crusher hammer to be replaced through the third moving component 25 to complete the positioning of the replacement mechanism 3.

[0074] Specifically, Figure 2 In this design, the drive wheel 252 employs a dual-wheel design, symmetrically distributed on both sides of the guide rail. The wheel profile fits snugly against the guide rail cross-section, achieving stable sliding through the contact between the wheel rim and the rail surface. The output shaft of the second motor 251 extends vertically upward and is connected to the axle of the drive wheel 252 via a gear set or coupling. When the motor starts, its rotational motion is directly transmitted to the drive wheel 252, causing it to roll along the guide rail and driving the entire third moving assembly 25 to move longitudinally.

[0075] The guide rail is shaped to match the drive wheel 252, ensuring that the drive wheel 252 can slide along the set longitudinal direction and avoid deviation. The guide rail is made of alloy steel, possessing rigidity and durability, and can withstand the forces generated by the drive wheel 252 sliding on its surface for extended periods. The guide rail is bolted to the second crossbeam 24, ensuring that the entire structure will not loosen or affect normal operation during device operation.

[0076] The second crossbeam 24 is made of H-beam steel, which provides sufficient strength to support the weight of the third moving component 25 and the replacement mechanism 3, and maintains structural stability during device movement and operation, preventing easy deformation.

[0077] The two ends of the second crossbeam 24 are connected to the top of the first dust cover 211 of the first moving component 21 and the second dust cover 221 of the second moving component 22 by bolts, so as to ensure the integrity of the whole device and provide stable support for the third moving component 25 to move in the longitudinal direction.
