Description

Technical Field

[0001] This invention relates to the field of rail vehicle assembly technology, specifically to an axle box spring snow cover assembly and its working method. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] As a key suspension component of high-speed trains, axle box springs are used to absorb and mitigate the impact and vibration of train operation, ensuring operational safety. To adapt to the effects of winter snow and prevent ice and snow from intruding between the spring bars and affecting the spring's deformation function during vehicle operation, a heat-shrinkable snow cover is required on the outer ring of the axle box spring. The snow cover is made of heat-shrinkable rubber, which, after heating, fits tightly against the outer ring of the axle box spring and has a certain degree of ductility.

[0004] Currently, there is a snow cover kit for high-speed train steel springs, which includes a loading and unloading station, a cover-fitting station, and a heat-shrinking station. The cover-fitting station is used to fit a snow cover onto the outer circumference of the high-speed train steel spring. When using this kit, the cover-fitting station is operated manually. During manual installation, it is necessary to ensure that the snow cover exposed at both ends of the spring is basically the same. This requires high skill from the operators. Moreover, manual installation results in high labor costs, high labor intensity, and cannot guarantee the quality of the installation. Summary of the Invention

Furthermore, the first linear telescopic component and the second linear telescopic component are staggered.

[0009] Optionally, the swing mechanism is also connected to a third linear telescopic member. The position of the third linear telescopic member corresponds to the area between the first arc-shaped plate and the second arc-shaped plate. The third linear telescopic member is connected to the limiting member, and the third linear telescopic member can drive the limiting member to extend into and leave the space between the first arc-shaped plate and the second arc-shaped plate.

[0010] Optionally, the swing mechanism includes a rotation drive, which is connected to a mounting base. The mounting base is connected to a second horizontal moving mechanism. The rotation drive is connected to one end of the swing arm, and the other end of the swing arm is provided with a spreading mechanism.

[0011] Optionally, a shaft box spring support platform is provided below the end of the second horizontal moving mechanism away from the transfer mechanism. The shaft box spring support platform is provided with a boss that matches the shaft box spring, and the boss is used to support the shaft box spring.

[0012] Optionally, a fourth linear telescopic member and a fifth linear telescopic member are provided on both sides of the boss, with the fourth linear telescopic member connected to the first pressure block and the fifth linear telescopic member connected to the second pressure block.

[0013] Optionally, the support includes a lifting plate connected to a lifting component, and a support block is provided in the middle of the lifting plate for engaging with the middle position of the stacked snow covers.

[0014] Optionally, the periphery of the lifting plate is provided with multiple stop plates, which are fixedly installed.

[0015] Optionally, the suction cup assembly includes a suction cup mounting plate with multiple suction cups connected to it. The suction cup mounting plate is connected to the lifting seat via a connecting component, and the lifting seat is connected to the vertical moving mechanism.

[0016] Optionally, the connecting assembly includes a vertically arranged sixth linear telescopic member, which is connected to the lifting seat.

[0017] Optionally, the suction cup passes through a through hole in the suction cup mounting plate and is slidably connected to the suction cup mounting plate, with an elastic element provided between the suction cup and the suction cup mounting plate.

[0018] Secondly, embodiments of the present invention provide a method for operating the axle box spring snow cover kit as described in the first aspect, comprising the following steps: The lifting mechanism uses a support component to raise the snow cover to the first preset position; The vertical moving mechanism drives the suction cup assembly to descend, and the suction cup assembly adheres to and fixes the snow cover. The vertical moving mechanism drives the suction cup assembly to rise, and the snow cover is initially opened. The first horizontal moving mechanism drives the initially opened snow cover to move towards the mounting mechanism to the second set position. The swing mechanism drives the opening mechanism to rotate to a horizontal state, and the second horizontal moving mechanism drives the opening mechanism to move toward the initially opened snow cover and extend into the snow cover. The opening mechanism opens, fully opening the snow cover, while the suction cup assembly separates from the snow cover; The second horizontal moving mechanism drives the opening mechanism and snow cover to move to the third set position above the axial spring, and the swinging mechanism drives the opening mechanism and snow cover to rotate to a vertical position and align with the axial spring. The lifting mechanism drives the expansion mechanism and snow cover to descend until they are fitted onto the outer circumference of the axle box spring. The expansion mechanism then retracts, and the lifting mechanism drives the expansion mechanism to reset.

[0019] The beneficial effects of this invention are as follows: 1. The axle box spring snow cover mounting device of the present invention includes a suction cup assembly. The suction cup assembly can adsorb the snow cover and initially open it under the drive of a first horizontal moving mechanism and a vertical moving mechanism. The opening mechanism is connected to a swinging mechanism, which is connected to a second horizontal moving mechanism. The swinging mechanism can drive the opening mechanism to a horizontal state, so that the opening mechanism can extend into the initially opened snow cover under the drive of the second horizontal moving mechanism. The opening mechanism can fully open the snow cover. The second horizontal moving mechanism can move the fully opened snow cover to above the axle box spring. The swinging mechanism can rotate the opening mechanism and the snow cover to a vertical position. Under the drive of a lifting mechanism, the snow cover can be fitted onto the outer circumference of the axle box spring. The whole process is automated, eliminating the need for manual fitting of the snow cover onto the axle box spring, reducing labor costs and labor intensity. At the same time, through the operation of the lifting mechanism, the first horizontal moving mechanism, and the second horizontal moving mechanism, the distance of the snow cover protruding from the end of the axle box spring can be guaranteed, improving the mounting quality.

[0020] 2. The axle box spring snow cover assembly of the present invention uses a boss to place the axle box spring, which can ensure the distance between the end of the snow cover protruding and the end of the axle box spring, thus ensuring the assembly quality. At the same time, a fourth linear telescopic member, a fifth linear telescopic member, a first pressure block, and a second pressure block are provided. Under the action of the fourth and fifth linear telescopic members, the first and second pressure blocks can press the end of the snow cover tightly against the outer side of the boss, preventing the snow cover from rising when the opening mechanism rises and detaches from the snow cover.

[0023] For ease of description, the words "upper" and "lower" appearing in this invention only indicate that they are consistent with the upper and lower directions of the accompanying drawings and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Example 1 This embodiment provides a snow cover kit for axle box springs, such as... Figures 1-3 As shown, the system includes a frame 1, which is fixed to the ground foundation. The frame 1 is equipped with a feeding mechanism, a transfer mechanism, and a fitting mechanism. A shaft box spring support platform 2 is provided on one side of the frame 1. The shaft box spring support platform 2 is used to place shaft box springs 3. The feeding mechanism is used to place multiple snow covers 4 in a stacked state. The transfer mechanism is used to pick up the snow covers 4, so that the snow covers 4 are initially opened. The transfer mechanism can also drive the initially opened snow covers 4 to move. The fitting mechanism is used to receive the initially opened snow covers 4 sent by the transfer mechanism, and fully open the snow covers 4. Finally, the snow covers 4 are fitted onto the outer periphery of the shaft box springs 3 on the shaft box spring support platform 2.

[0025] The feeding mechanism includes a lifting component 5, which is connected to a support component. The support component is used to place multiple stacked snow covers 4.

[0026] In this embodiment, the lifting component 5 is a vertically arranged electric telescopic rod or a screw lifting mechanism or other device capable of outputting lifting motion. Those skilled in the art can set it according to actual needs, and it will not be described in detail here.

[0027] The lifting component 5 is located inside a box at the bottom of the frame 1. The top wall of the box has an opening through which the lifting component 5 extends.

[0028] The support includes a lifting plate 6, which is a rectangular plate. A cuboid support block 7 is provided at the center of the lifting plate 6. The support block 7 is used to support the middle position of the snow cover 4 in the stacked column state and to provide support force when the middle position of the snow cover 4 is under pressure.

[0029] Multiple stop plates 8 are provided around the lifting plate 6. The stop plates 8 are rectangular plates. The bottom end of the stop plate 8 is fixed to the fixed plate 9. The fixed plate 9 is located below the lifting plate 6. The four corners of the fixed plate 9 are fixedly connected to the top surface of the box through support columns. The stop plates 8 play a blocking role around the lifting plate 6 to prevent the snow cover 4 from falling off the support.

[0030] It is understandable that the support component also adopts an integrated inverted T-shaped structure, which can be set according to actual needs by those skilled in the art, and will not be described in detail here.

[0031] Correspondingly, the fixing plate 8 is provided with an opening for the lifting component 5 to pass through.

[0032] The transfer mechanism includes a first horizontal moving mechanism 10, which is located above the feeding mechanism. The first horizontal moving mechanism 10 is connected to the vertical moving mechanism 11 and can drive the vertical moving mechanism 11 to move in the horizontal direction.

[0033] The vertical moving mechanism 11 is connected to the suction cup assembly. The first horizontal moving mechanism 10 can drive the vertical moving mechanism 11 to move to the position corresponding to the feeding mechanism. At this time, the suction cup assembly is located directly above the support. The vertical moving mechanism 11 can drive the suction cup assembly to descend, so that the suction cup assembly cooperates with the snow cover 4 and the position of the suction cup assembly corresponds to the support block 7. The suction cup assembly can cooperate with the support block 7 to apply pressure to the snow cover 4, so that the suction cup assembly is adsorbed and fixed to the snow cover 4 located at the top.

[0034] The first horizontal moving mechanism 10 can be any existing device capable of outputting horizontal motion. For example, the first horizontal moving mechanism 10 can be a horizontally arranged lead screw mechanism, synchronous belt mechanism, or gear and rack mechanism. Those skilled in the art can set it according to actual needs. Preferably, the first horizontal moving mechanism 10 is a horizontally arranged first lead screw mechanism, and the moving part of the first lead screw mechanism is connected to the vertical moving mechanism.

[0035] The vertical moving mechanism 11 can be any existing device capable of outputting vertical motion, such as a vertically arranged screw mechanism, synchronous belt mechanism, or gear and rack mechanism. Those skilled in the art can set it according to actual needs. Preferably, the vertical moving mechanism 11 adopts a vertically arranged second screw mechanism. The moving part of the second screw mechanism is connected to the suction cup assembly, which can drive the suction cup assembly to perform vertical lifting and lowering movements.

[0036] like Figure 4 As shown, the suction cup assembly includes a suction cup mounting plate 12, which is connected to a lifting seat 13 via a connecting component. The lifting seat 13 is connected to the moving part of a vertical moving mechanism 11, which can drive the suction cup mounting plate 12 to perform vertical lifting and lowering movements via the lifting seat 13 and the connecting component.

[0037] The suction cup mounting plate 12 is provided with multiple suction cups 14, which are used to adsorb and fix the snow cover 4.

[0038] In one embodiment, the connecting assembly uses multiple connecting columns 15, and the lifting seat 13 is connected to the suction cup mounting plate 12 through the multiple connecting columns 15. In this way, the vertical moving mechanism 11 applies downward pressure to the suction cup 14 so that the suction cup 14 is adsorbed and fixed to the snow cover 4.

[0039] In another embodiment, the connecting assembly includes a sixth linear telescopic member, which is vertically arranged. The fixed part of the sixth linear telescopic member is fixed to the lifting seat 13, and its telescopic part is fixedly connected to the connecting plate. The connecting plate is connected to the suction cup mounting plate 12 through multiple connecting columns 15. In this way, the vertical moving mechanism 11 can be used to apply downward pressure to the suction cup 14, or the sixth linear telescopic member can be used to apply downward pressure to the suction cup.

[0040] The sixth linear telescopic component can be any device capable of outputting linear telescopic motion, such as a cylinder, hydraulic cylinder, or electric telescopic rod. In this embodiment, the sixth telescopic component is a sixth cylinder 16. The cylinder body of the sixth cylinder 16 is connected to the lifting seat 13, and its piston rod is connected to the connecting plate.

[0041] Furthermore, since the snow cover 4 is made of flexible material, there will be unevenness when its middle part is placed on the surface of the support block 7. Therefore, in this embodiment, the suction cup 14 is slidably connected to the suction cup mounting plate 12, and the suction cup 14 can move vertically relative to the suction cup mounting plate 12. An elastic element is provided between the suction cup 14 and the suction cup mounting plate 12 to apply elastic force to the suction cup 14.

[0042] In this embodiment, the suction cup 14 includes an adsorption part and a connecting part. The adsorption part can adopt the existing suction cup structure. The bottom end of the adsorption part is fixedly connected to the connecting part. The connecting part is a cylindrical tube. The cylindrical tube is connected to the internal space of the adsorption part. The cylindrical tube passes through the through hole provided in the suction cup mounting plate 12 and is slidably connected to the suction cup mounting plate 12.

[0043] The elastic element is a spring, which is sleeved on the outer circumference of the cylindrical tube. The bottom end of the spring is fixedly connected to the annular baffle at the bottom end of the cylindrical tube, and the top end of the spring is connected to the baffle set on the bottom surface of the suction cup mounting plate 12.

[0044] Furthermore, the top end of the cylindrical tube is provided with a limiting boss to prevent the cylindrical tube from detaching from the suction cup mounting plate 12 under the action of the spring.

[0045] The top of the cylindrical tube is equipped with a connector, which is connected to an air pump via an air pipe. The air pump is used to fill the adsorption section with gas, thereby achieving the state where the adsorption section is released from the snow cover 4. At the same time, the air pump can also extract the gas from the adsorption section, thereby making the adsorption section adhere to the snow cover 4.

[0046] An existing air pump capable of both inflation and deflation can be used, and will not be described in detail here.

[0047] The assembly includes a second horizontal moving mechanism 17, which is connected to a lifting mechanism installed on the top of the frame 1. The lifting mechanism can drive the second horizontal moving mechanism 17 to move up and down. The second horizontal moving mechanism 17 is parallel to the first horizontal moving mechanism 10. The moving part of the second horizontal moving mechanism 17 is connected to a swing mechanism, which is connected to a spreading mechanism. The swing mechanism can drive the spreading mechanism to swing in the vertical plane, thereby realizing the switching between the horizontal and vertical states of the spreading mechanism.

[0048] The second horizontal moving mechanism 17 can be any existing equipment, such as a horizontally arranged lead screw mechanism, synchronous belt mechanism, or gear and rack mechanism. Those skilled in the art can set it according to actual needs. In this embodiment, the second horizontal moving mechanism 17 adopts a horizontally arranged third lead screw mechanism, and the moving part of the third lead screw mechanism is connected to the swing mechanism.

[0049] The lifting mechanism adopts a cylinder, hydraulic cylinder, or screw mechanism with the axis arranged vertically. Those skilled in the art can set it according to actual needs. In this embodiment, the lifting mechanism adopts a seventh cylinder 18 with the axis arranged vertically. The cylinder body of the seventh cylinder 18 is fixed on the cylinder mounting plate at the top of the frame 1. Its piston rod is connected to the second horizontal moving mechanism 17, which can drive the second horizontal moving mechanism 17 to perform vertical lifting and lowering movements.

[0050] Furthermore, the second horizontal moving mechanism 17 is fixedly connected to the bottom end of a plurality of guide columns 19. The guide columns 19 pass through the guide sleeve provided on the cylinder mounting plate and are slidably connected to the guide sleeve. Through the cooperation of the guide sleeve and the guide column 19, the lifting and lowering movement of the second horizontal moving mechanism 17 is guided.

[0051] The swing mechanism includes a rotation drive component, which is a device such as a motor or servo motor capable of outputting rotational motion. The rotation drive component is fixed on the mounting base 20, which is connected to the moving part of the second horizontal moving mechanism 17. The output shaft of the rotation drive component is rotatably connected to the mounting base 20 through a bearing. Its output shaft surface is vertically fixedly connected to one end of the swing arm 21. The other end of the swing arm 21 is connected to a spreading mechanism. The output shaft of the rotation drive component can drive the swing arm 21 to swing in the vertical plane, thereby realizing the switching of the spreading mechanism between the vertical and horizontal postures.

[0052] In other embodiments, the swing mechanism may also be a swing cylinder or a crank rocker mechanism, etc., which can be set according to actual needs by those skilled in the art, and will not be described in detail here.

[0053] like Figures 5-6As shown, the opening mechanism includes a first arc plate 22 and a second arc plate 23 arranged opposite to each other. Both the first arc plate 22 and the second arc plate 23 are arc-shaped plates with a central angle of less than 180°, so that the first arc plate 22 and the second arc plate 23 can contract and open.

[0054] The first arc plate 22 and the second arc plate 23 are connected to the spreading drive assembly. The spreading drive assembly can drive the first arc plate 22 and the second arc plate 23 to move synchronously toward each other or away from each other. The spreading drive assembly is installed on the support base 25, and the support base 25 is fixedly connected to the end of the swing arm 21.

[0055] The expansion drive assembly includes a first linear telescopic member and a second linear telescopic member. The first and second linear telescopic members are arranged in parallel. The fixed parts of the first and second linear telescopic members are fixed on the support base 25. Their telescopic parts extend in opposite directions. The telescopic part of the first linear telescopic member is fixed to the end of the first arc plate 22, and the telescopic part of the second linear telescopic member is fixed to the end of the second arc plate 23.

[0056] The first and second linear telescopic components are made of devices capable of outputting linear telescopic motion, such as cylinders, hydraulic cylinders, or electric telescopic rods. In this embodiment, the first linear telescopic component is a first cylinder 24, the cylinder body of the first cylinder 24 is fixed to the support base 25, and its piston rod is fixed to the end of the first arc plate 22 through an L-shaped plate. The second linear telescopic component is a second cylinder 26, the cylinder body of the second cylinder 26 is fixed to the support base, and its piston rod is fixed to the end of the second arc plate 23 through an L-shaped plate.

[0057] The axes of the first cylinder 24 and the second cylinder 26 are located on the same straight line or are staggered. In this embodiment, in order to reduce the space occupied by the first cylinder 24 and the second cylinder 26, the axes of the first cylinder 24 and the second cylinder 26 are staggered.

[0058] The first cylinder 24 and the second cylinder 26 can drive the first arc plate 22 and the second arc plate 23 to move synchronously towards and away from each other, thereby realizing the switching between the contraction and opening states of the spreading mechanism.

[0059] Furthermore, the swing mechanism is also connected to a third linear telescopic component. The third linear telescopic component is a device capable of outputting linear telescopic motion, such as a cylinder or hydraulic cylinder. Preferably, the third linear telescopic component is a third cylinder 27. The cylinder body of the third cylinder 27 is fixed to the swing arm 21. The position of the third cylinder 27 corresponds to the area between the first arc plate 22 and the second arc plate 23. The piston rod of the third cylinder 27 is connected to a limiting member 28, which is an L-shaped plate. The third cylinder 27 can drive the limiting member 28 to extend between the first arc plate 22 and the second arc plate 23. When the first arc plate 22 and the second arc plate 23 contract, they can contact the limiting member 28 to limit their degree of contraction. When the first arc plate 22 and the second arc plate 23 are located on the outer periphery of the axle box spring 3, it can prevent the first arc plate 22 and the second arc plate 23 from contacting the axle box spring 3 and causing damage to the axle box spring 3.

[0060] The axle box spring support platform 2 is located below the end of the second horizontal moving mechanism 17 away from the transfer mechanism. The top surface of the axle box spring support platform 2 is provided with a boss 29 that matches the axle box spring. In this embodiment, the boss 29 is a cylindrical boss. The axle box spring 3 is placed on the upper surface of the boss 29. The thickness of the boss 29 matches the length of the snow cover 4 protruding from the end of the axle box spring 3, thereby ensuring that the length of the snow cover 4 protruding from the end of the axle box spring 3 is sufficient.

[0061] The boss 29 is provided with a third linear telescopic member and a fourth linear telescopic member on both sides. The third linear telescopic member and the fourth linear telescopic member are arranged opposite to each other, that is, the third linear telescopic member and the fourth linear telescopic member are arranged at a circumferential interval of 180° relative to the boss.

[0062] In this embodiment, the third and fourth linear telescopic components are devices capable of outputting linear telescopic motion, such as cylinders, hydraulic cylinders, or electric telescopic rods. Preferably, the third linear telescopic component is a third cylinder, and the fourth linear telescopic component is a fourth cylinder. The cylinder bodies of the third and fourth cylinders are fixed on the top surface of the axle box spring support platform. The piston rod of the third cylinder is connected to the first pressure block 30, and the piston rod of the fourth cylinder is connected to the second pressure block 31. The opposing sides of the first pressure block 30 and the second pressure block 31 adopt an arc-shaped surface that matches the boss 29.

[0063] After the snow cover 4 is fitted onto the outer periphery of the axle box spring 3, the third cylinder and the fourth cylinder drive the first pressure block 30 and the second pressure block 31 to move toward the boss 29. The first pressure block 30 and the second pressure block 31 can press the part of the snow cover 4 located in the gap between the first arc plate 22 and the second arc plate 23 onto the boss 29, thereby fixing the snow cover 4 and preventing the snow cover 4 from moving upward with the opening mechanism when the opening mechanism moves upward.

[0064] In this embodiment, each cylinder, rotary drive component, first horizontal moving mechanism, second horizontal moving mechanism, vertical moving mechanism, lifting component, etc., is connected to the control system inside the housing and can receive instructions from the control system to perform operations.

[0065] The control system is connected to the operator panel 32, allowing operators to send commands to the control system via the operator panel.

[0066] Example 2 This embodiment provides a method for operating the axle box spring snow cover kit as described in Embodiment 1, such as... Figure 7 As shown, it includes the following steps: Step 1: The lifting component 5 lifts the stacked snow covers 4 to the first set position through the support component. The first set position allows the suction cup assembly to descend and contact the snow cover 4. The first set position can be set according to actual needs and will not be described in detail here.

[0067] Step 2: The vertical moving mechanism 11 drives the suction cup assembly to descend until the suction cup 14 of the suction cup assembly contacts the uppermost snow cover 4. The vertical moving mechanism 11 continues to drive the suction cup assembly to descend, applying downward pressure to the suction cup 14 until the suction part of the suction cup 14 is attached and fixed to the uppermost snow cover 4. In this step, the sixth cylinder 16 can also be driven to increase the downward pressure of the suction cup 14 and ensure that the suction cup 14 is attached and fixed to the snow cover 4.

[0068] Step 3: After the suction cup 14 is attached and fixed to the snow cover 4, the vertical moving mechanism 11 drives the snow cover 4 to rise, while the lifting component 5 drives the support component to fall. The snow cover 4 is initially opened under its own weight. The first horizontal moving mechanism 10 drives the vertical moving mechanism 11 and the snow cover 4 to move in a straight line towards the second horizontal moving mechanism 17 until the initially opened snow cover 4 moves to the second set position.

[0069] Step 3: Rotate the drive component to drive the swing arm 21 to swing, so that the retracted opening mechanism moves to a horizontal position. The second horizontal moving mechanism 17 drives the opening mechanism to move horizontally in a straight line towards the snow cover 4 until the opening mechanism extends into the snow cover 4.

[0070] Step 4: The first cylinder 24 and the second cylinder 26 drive the first arc plate 2 and the second arc plate 23 to move away from each other. The first arc plate 22 and the second arc plate 23 are used to fully open the snow cover 4. The air pump inflates the suction cup 14, so that the suction part of the suction cup 14 is released from the suction fixation state with the snow cover 4.

[0071] Step 5: The second horizontal moving mechanism 17 drives the spreading mechanism and the snow cover 4 to move away from the first horizontal moving mechanism 10 until they move to the third set position, which matches the position of the axle box spring 3 that is pre-placed on the axle box spring support 2.

[0072] Step 6: The lifting mechanism drives the spreading mechanism and snow cover 4 to descend until the bottom of the snow cover 4 contacts the top surface of the axle box spring support platform 2. At this time, the first arc plate 22, the second arc plate 23 and the snow cover 4 are all located on the outer periphery of the axle box spring 3.

[0073] Step 7: The third cylinder 27 operates, extending the limiting member 28 between the top ends of the first arc plate 22 and the second arc plate 23. The first cylinder 24 and the second cylinder 26 drive the first arc plate 22 and the second arc plate 23 to move towards each other until the first arc plate 22 and the second arc plate 23 contact the limiting member 28. At this time, the snow cover 4 is released from its fully open state, and the first arc plate 22 and the second arc plate 23 are separated from the inner side of the snow cover 4. The fourth cylinder and the fifth cylinder operate, pressing the bottom end of the snow cover 4 against the side of the boss 29 through the first pressing block 30 and the second pressing block 31.

[0074] Step 8: The lifting mechanism drives the spreading mechanism to rise and reset. After the spreading mechanism rises to the target height, the third cylinder 27 retracts, causing the limiting piece 28 to move away from the position between the first arc plate 22 and the second arc plate 23. The first cylinder 24 and the second cylinder 26 drive the first arc plate 22 and the second arc plate 23 to move in opposite directions. The spreading mechanism returns to the fully retracted state, waiting for the next snow cover 4 to be installed.
