Automatic stacking stereoscopic warehouse for piston head products

Abstract

This invention discloses an automated stacking warehouse for piston head products in the field of piston head processing technology, including an automated warehouse rack and a stacking and retrieval mechanism. The stacking and retrieval mechanism includes an operating unit, which comprises a top seat and a receiving base arranged vertically at intervals. Several sets of fork mechanisms are arranged between the top seat and the receiving base. Each fork mechanism has vertical guide rails slidably fitted on both sides. The fork mechanisms are driven by a drive mechanism to move up and down along the vertical guide rails. Each set of fork mechanisms is equipped with a locking linkage mechanism. This invention establishes a controllable power connection between each fork mechanism and a drive mechanism by setting several sets of fork mechanisms and cooperating with the locking linkage mechanism.

This facilitates the storage and retrieval of batch piston head products and improves storage and retrieval efficiency.

Description

Technical Field

[0001] This invention relates to the field of piston head products, and more specifically to an automated stacking warehouse for piston head products. Background Technology

[0002] With the rapid development of modern manufacturing, piston head products, as key moving parts in internal combustion engines, compressors and hydraulic equipment, have seen continuous growth in annual output and variety, placing higher demands on the automation and intelligence of the warehousing process during production.

[0003] Currently, the storage of piston head products typically relies on pallets and is achieved through traditional automated storage and retrieval systems (AS / RS). Traditional AS / RS usually include racks for placing products and stacker cranes for stacking and retrieving products. However, most stacker cranes are single-fork structures, which can only handle one pallet at a time. When faced with the need for bulk inbound and outbound storage of piston head products, the stacker cranes need to repeatedly shuttle through the aisles to retrieve and store each item individually, resulting in low storage and retrieval efficiency and high energy consumption. Therefore, we propose an automated stacking AS / RS for piston head products. Summary of the Invention

[0004] The purpose of this invention is to provide an automated stacking warehouse for piston head products, which solves the technical problems mentioned in the background section.

[0005] The present invention achieves the above objectives through the following technical solutions: An automated stacking warehouse for piston head products includes an automated warehouse rack and a stacking and retrieval mechanism for stacking or retrieving piston head products at the automated warehouse rack. The stacking and unloading mechanism includes an operating part that can move along the length of the automated warehouse rack. The operating part includes a top seat and a receiving base that are spaced apart vertically. Several sets of fork mechanisms are provided between the top seat and the receiving base. The fork mechanisms can move into the inner cavity of the receiving base. Vertical guide rails are slidably fitted on both sides of the fork mechanisms. The two ends of the vertical guide rails are fixed to the bottom of the top seat and the bottom wall of the receiving base, respectively. The fork mechanisms are driven by a drive mechanism located between the top seat and the receiving base to move up and down along the vertical guide rails. Each set of fork mechanisms is provided with a locking linkage mechanism. The locking linkage mechanism is used to lock the fork mechanism with the drive mechanism and release the lock between the fork mechanism and the vertical guide rail, so that the drive mechanism drives the fork mechanism to move up and down. It is also used to release the lock between the fork mechanism and the drive mechanism and lock the fork mechanism with the vertical guide rail, so that the fork mechanism is in a preset position on the vertical guide rail.

[0006] A further improvement is that the fork mechanism includes a support plate, the side wall of which is provided with a guide slider for sliding within a vertical guide rail, a connecting plate on the support plate, and two sets of forks symmetrically arranged on the side of the connecting plate facing the automated warehouse rack. The connecting plate is connected to the support plate through a linear drive module, which is used to drive the forks to approach or move away from the automated warehouse rack for stacking or removing piston head products.

[0007] A further improvement is that the drive mechanism includes a lifting screw that is vertically rotatably disposed between the receiving base and the top seat, and a drive device disposed on the top seat for driving the lifting screw to rotate. The bearing plate has a movable opening for the lifting screw to pass through and cooperate with the locking linkage mechanism. The diameter of the movable opening is larger than the outer diameter of the lifting screw.

[0008] A further improvement is that the bearing plate has an assembly cavity for accommodating the locking linkage mechanism. The inner cavity of the guide slider is connected to the assembly cavity. The locking linkage mechanism includes several sets of locking pins inserted in a ring array into the inner wall of the movable opening. A threaded sleeve is movably provided in the movable opening along the same axis. The threaded sleeve is provided on the outer wall of the lifting screw. The outer wall of the threaded sleeve has locking grooves evenly provided in a ring array for the insertion of the locking pins. An elastic element is provided at the connection between the locking pin and the bearing plate. The inner end of the locking pin extends into the assembly cavity and is connected to the transmission part one. Locking blocks are symmetrically inserted on both sides of the guide slider. Locking openings for the insertion of locking blocks are evenly provided on the outer wall of the vertical guide rail along its height direction. A transmission part two is provided in the assembly cavity for transmission connection with the locking blocks. A drive gear is provided between the transmission part one and the transmission part two. The drive gear is located in the assembly cavity through a rotating device. When the rotating device drives the drive gear to rotate in a preset direction, the first transmission part drives the locking pin into the locking groove, and the second transmission part drives the locking block to disengage from the locking port. When the rotating device drives the drive gear to rotate to a reset position, the first transmission part drives the locking pin to disengage from the locking groove, and the second transmission part drives the locking block to enter the locking port.

[0009] A further improvement is that the transmission part includes a toothed ring rotatably disposed in the assembly cavity and coaxial with the movable opening. The toothed ring meshes with the drive gear. The toothed ring is also sleeved on the outside of the locking pin. The inner wall of the toothed ring is provided with a number of protrusions in a ring array that correspond one-to-one with the locking pin. When the rotating device drives the drive gear to rotate in a preset direction, the gear ring is driven to rotate so as to push the locking pin into the corresponding locking groove through the protrusion.

[0010] A further improvement is that the transmission part two includes a driven rack one horizontally disposed in the assembly cavity and meshing with the drive gear. A driven rack two parallel to the driven rack one is disposed at a distance from the side of the driven rack one away from the drive gear. Both driven rack one and driven rack two are slidably disposed in the assembly cavity and staggered from each other. A driven gear is meshed between driven rack one and driven rack two. The driven gear is rotatably disposed in the assembly cavity. Each of the opposite ends of driven rack one and driven rack two is provided with a connecting frame. Each connecting frame is hinged to two sets of locking blocks on the corresponding guide slider through two sets of connecting rods. When the rotating device drives the drive gear to rotate in a preset direction, the gear ring drives the driven rack one to move in the preset direction, and then the driven gear drives the driven rack two to move in the opposite direction to the driven rack one, thereby driving the corresponding locking block to move into the inner cavity of the guide slider through the connecting frame and the connecting rod to disengage from the locking port.

[0011] A further improvement is that the support plate is provided with a detection device for detecting the position of the fork component, and at least one locking block is embedded in the fork component. The locking block is driven by a telescopic device provided on the fork component to extend or retract relative to the fork component. The detection device is signal-connected to the telescopic device. When the detection device detects that the fork component has moved to a preset position, it triggers the telescopic device to drive the locking block to extend to the outside of the fork component.

[0012] A further improvement is that the opposite sides of the top seat and the receiving base are respectively connected to the horizontal guide rail via a moving mechanism.

[0013] The beneficial effects of this invention are as follows: This invention establishes a controllable power connection between each fork mechanism and a drive mechanism by setting up several sets of fork mechanisms and cooperating with a locking linkage mechanism. This allows a single drive mechanism to sequentially drive each set of fork mechanisms to the target position and lock them independently, thereby enabling multiple sets of fork mechanisms to be put into operation at the same time. This facilitates the storage and retrieval of batch piston head products, improves storage and retrieval efficiency, and solves the problem of low efficiency and high energy consumption caused by the need for traditional single-fork stacker cranes to repeatedly shuttle through aisles. Meanwhile, the height of each fork mechanism can be independently and flexibly adjusted according to the storage and retrieval position, improving the flexibility of use, while the idle fork mechanism can be retracted downward into the inner cavity of the base, reducing vertical space occupation and energy consumption.

Detailed Implementation

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1

[0018] Please see the appendix Figure 1-3 An automated stacking warehouse for piston head products, wherein the piston head product in this embodiment typically includes a piston head body and a pallet for supporting the piston head body; The automated stacking warehouse includes a warehouse rack 100 and a stacking and retrieval mechanism 200 for stacking or retrieving piston head products at the warehouse rack 100. The stacking and unloading mechanism 200 includes an operating part that can move along the length of the automated warehouse rack 100. The operating part includes a top seat 202 and a receiving base 201 that are spaced apart vertically. In this embodiment, the top of the receiving base 201 and the side near the automated warehouse rack 100 are hollow. Several sets of fork mechanisms 206 are provided between the top seat 202 and the receiving base 201. The fork mechanisms 206 can move downward into the inner cavity of the receiving base 201 to achieve storage and clearance when not in use. Vertical guide rails 208 are slidably fitted on both sides of the fork mechanisms 206. In this embodiment, four sets of vertical guide rails 208 can be provided, that is, two sets are provided on each of the left and right sides of the fork mechanisms 206. U-shaped guide rails are preferred. The two ends of the vertical guide rails 208 are fixed to the bottom of the top seat 202 and the bottom wall of the receiving base 201, respectively. The fork mechanisms 206 are provided on the top seat 202 and the receiving base 201, respectively. The drive mechanism between the seat 202 and the receiving base 201 drives the fork mechanism 206 to move up and down along the vertical guide rail 208 to adjust the position of the fork mechanism 206. Each fork mechanism 206 is provided with a locking linkage mechanism 207, which can selectively switch to a first working state or a second working state. In the first working state, the locking linkage mechanism 207 is used to lock the fork mechanism 206 with the drive mechanism and release the lock between the fork mechanism 206 and the vertical guide rail 208, so that the drive mechanism drives the fork mechanism 206 to move up and down. In the second working state, the locking linkage mechanism 207 is also used to release the lock between the fork mechanism 206 and the drive mechanism and lock the fork mechanism 206 with the vertical guide rail 208, so that the fork mechanism 206 is in a preset position on the vertical guide rail 208 and will not be driven by the drive mechanism. With the above structural configuration, operators or control systems can flexibly adjust the number of fork mechanisms 206 in use according to the number of piston head products to be stacked or retrieved. During adjustment, the fork mechanisms 206 currently idle in the receiving base 201 are controlled sequentially from top to bottom. By switching their locking linkage mechanism 207 to the first working state, the fork mechanism 206 is locked and engaged with the drive mechanism. Then, the drive mechanism drives it to rise to the working height, thus realizing the step-by-step deployment of the fork mechanisms 206. When adjusting the vertical spacing between the deployed fork mechanisms 206, or when it is necessary to independently control the lifting and lowering of a specific fork mechanism 206 to adapt to different storage locations, the remaining fork mechanisms 206 that do not need to move temporarily remain in the second working state, that is, locked and fixed on the vertical guide rail 208, so that they will not follow the displacement due to the overall movement of the drive mechanism. This method is highly flexible and meets the needs of stacking and retrieving piston head products in batches, improving the overall operation efficiency.

[0019] Preferably, the fork mechanism 206 in this embodiment includes a support plate 2061. The side wall of the support plate 2061 is provided with a guide slider 2063 for sliding within the vertical guide rail 208. In this embodiment, the guide slider 2063 is integrally formed with the support plate 2061. A connecting plate 2064 is provided on the support plate 2061. Two sets of forks 2065 are symmetrically provided on the side of the connecting plate 2064 facing the automated warehouse rack 100. The forks 2065 can be inserted into the tray at the bottom of the piston head product to achieve lifting and placement. The connecting plate 2064 is connected to the support plate 2061 through a linear drive module 2062. The linear drive module 2062 is used to drive the forks 2065 to approach or move away from the automated warehouse rack 100 to perform stacking or removal operations of the piston head product. The linear drive module 2062 can be a rodless cylinder, an electric cylinder with a guide rail, or a servo motor driven screw and nut mechanism. The choice is made according to the actual situation and will not be described in detail here.

[0020] Please see the appendix Figure 3-4 Preferably, the drive mechanism of this embodiment includes a lifting screw 204 vertically rotatably disposed between the receiving base 201 and the top seat 202, and a drive device 205 disposed on the top seat 202 for driving the lifting screw 204 to rotate; a bearing is provided at the connection between the lifting screw 204 and the receiving base 201 and the top seat 202. In this embodiment, the lifting screw 204 is specifically located between the receiving base 201 and the top seat 202 and on the side away from the three-dimensional warehouse rack 100. In this embodiment, the drive device 205 can be a servo motor and a reducer. The support plate 2061 has an opening for the lifting screw 204 to pass through and cooperate with the locking linkage mechanism 207. The diameter of the opening is larger than the outer diameter of the lifting screw 204.

[0021] Please see the appendix Figure 3-4 Preferably, in this embodiment, the support plate 2061 has an assembly cavity 2067 for accommodating the locking linkage mechanism 207, and the inner cavity of the guide slider 2063 is connected to the assembly cavity 2067. The locking linkage mechanism 207 includes several sets of locking pins 2073 inserted in a circular array into the inner wall of the movable opening. For example, in this embodiment, four sets of locking pins 2073 are provided. Threaded sleeves 20710 are movably arranged along the same axis inside the movable opening. The threaded sleeves 20710 are threaded onto the outer wall of the lifting screw 204. The outer wall of the threaded sleeves 20710 is evenly provided with locking grooves in a circular array for the locking pins 2073 to insert into. When the locking pins 2073 are not inserted into the locking grooves, the rotation of the lifting screw 204 only causes the threaded sleeves 20710 to rotate freely. After the locking pins 2073 are inserted into the locking grooves, the lifting screw 204 drives the bearing plate 2061 to rise and fall along the vertical guide rail 208 through the threaded sleeves 20710. An elastic element is provided at the connection between the locking pins 2073 and the bearing plate 2061. The first elastic element is a spring, one end of which is connected to the inner end of the outer wall of the locking pin 2073, and the other end is connected to the inner wall of the assembly cavity 2067. It is used to ensure that the locking pin 2073 is always disengaged from the locking groove under normal conditions. The inner end of the locking pin 2073 extends into the assembly cavity 2067 and is connected to the first transmission part. Locking blocks 2079 are symmetrically inserted on both sides of the guide slider 2063. The outer wall of the vertical guide rail 208 is evenly provided with locking holes 2081 for the locking blocks 2079 to be inserted along its height direction. The second transmission part is provided in the assembly cavity 2067 for the transmission connection with the locking blocks 2079. A drive gear 2071 is provided between the first transmission part and the second transmission part. The drive gear 2071 is located in the assembly cavity 2067 through a rotating device (such as a stepper motor and a servo motor). When the rotating device drives the drive gear 2071 to rotate in a preset direction, the first transmission part drives the locking pin 2073 into the locking groove, and the second transmission part drives the locking block 2079 to disengage from the locking port 2081, thereby realizing the power engagement between the bearing plate 2061 and the lifting screw 204 and the locking release from the vertical guide rail 208; when the rotating device drives the drive gear 2071 to rotate in a reset position, the first transmission part drives the locking pin 2073 to disengage from the locking groove, and the second transmission part drives the locking block 2079 into the locking port 2081, thereby realizing the power disconnection between the bearing plate 2061 and the lifting screw 204 and the locking fixation from the vertical guide rail 208.

[0022] Please see the appendix Figure 1-2 Preferably, in this embodiment, the top seat 202 and the receiving base 201 are respectively connected to the horizontal guide rail 203 through a moving mechanism on opposite sides. The upper and lower horizontal guide rails 203 can be fixed on the outer support beam. In this embodiment, the moving mechanism can drive the operating part to move back and forth along the horizontal guide rail 203 to realize the position switching of the operating part in the length direction of the three-dimensional warehouse rack 100. The moving mechanism can adopt a gear and rack transmission mechanism, or it can adopt a motor to drive the roller to move in the horizontal guide rail 203, etc., which will not be described in detail here.

[0023] Example 2

[0024] Please see the appendix Figure 3-4 Based on Embodiment 1, the transmission part of this embodiment includes a gear ring 2072 that is rotatably disposed in the assembly cavity 2067 via a bearing and is coaxial with the movable opening. The gear ring 2072 meshes with the drive gear 2071. The gear ring 2072 is also sleeved on the outside of the locking pin 2073. The inner wall of the gear ring 2072 is provided with a plurality of protrusions 2074 that correspond one-to-one with the locking pin 2073 in a ring array. The protrusion 2074 is, for example, an arc-shaped protrusion, and has a smoothly transitioned guide surface on the side facing the locking pin 2073. A ball can be embedded in the inner end of the locking pin 2073 to cooperate with it. When the rotating device drives the drive gear 2071 to rotate in a preset direction, the gear ring 2072 is driven to rotate by the drive gear 2071. The protrusions 2074 on the inner wall of the gear ring 2072 rotate with the gear ring 2072 and gradually contact the inner end of the corresponding locking pin 2073. Through the pushing action of the protrusions 2074, each locking pin 2073 is pushed to move radially inward synchronously into the corresponding locking groove. When the rotating device rotates in the reverse direction to reset, the gear ring 2072 drives the protrusions 2074 to reverse and disengage from the locking pins 2073. Under the reset action of the elastic element, the locking pins 2073 automatically exit the locking groove and return to the initial disengaged state.

[0025] Preferably, the transmission unit two in this embodiment includes a driven rack 2075 horizontally disposed within the assembly cavity 2067 and meshing with the drive gear 2071. Both sides of the driven rack 2075 have toothed segments. A driven rack 2076 parallel to the driven rack 2075 is disposed at a distance from the side of the driven rack 2075 away from the drive gear 2071. Both the driven rack 2075 and the driven rack 2076 are slidably disposed within the assembly cavity 2067 and staggered from each other. In this embodiment, the driven rack 2075... Both driven rack 2075 and driven rack 2076 can slide against a slide rail located on the inner wall of assembly cavity 2067 via a slider fixed thereon, ensuring that the two sets of driven racks maintain stable linear motion without deviation during transmission. A driven gear 2077 meshes between driven rack 1 2075 and driven rack 2076 to allow the two sets of driven racks to move towards each other or away from each other. The driven gear 2077 is rotatably located within assembly cavity 2067. Each of the two racks 2076 has a connecting frame at one of its opposite ends. The connecting frame is perpendicular to the driven rack. Each connecting frame is hinged to two sets of locking blocks 2079 on the corresponding guide slider 2063 via two sets of connecting rods 2078. That is, one end of the connecting rod 2078 is hinged to the connecting frame, and the other end is hinged to the corresponding locking block 2079. This converts the linear motion of the driven rack into the radial displacement of the locking block 2079. When the driven rack 1 2075 and the driven rack 2 2076 move away from each other and outwards simultaneously... When in motion, the connecting frame drives the two sets of locking blocks 2079 to move away from each other via the connecting rod 2078 so as to insert into the locking port 2081 on the vertical guide rail 208, thereby locking and fixing the bearing plate 2061 to the vertical guide rail 208. When the driven rack 1 2075 and the driven rack 2 2076 move closer to each other and inwards synchronously, the connecting frame drives the two sets of locking blocks 2079 to move closer to each other via the connecting rod 2078 so as to exit the locking port 2081, thereby releasing the locking relationship between the bearing plate 2061 and the vertical guide rail 208. When the rotating device drives the drive gear 2071 to rotate in a preset direction, the gear ring 2072 drives the driven rack 2075 to move in the preset direction, and then the driven gear 2077 drives the driven rack 2076 to move in the opposite direction to the driven rack 2075. This causes the corresponding locking block 2079 to move into the inner cavity of the guide slider 2063 through the connecting frame and connecting rod 2078 to disengage from the locking port 2081.

[0026] Example 3

[0027] Please see the appendix Figure 3Based on Embodiment 1, this embodiment provides a detection device on the support plate 2061 for detecting the position of the fork member 2065. This detection device may include, for example, an infrared beam sensor or a laser rangefinder. At least one locking block 2066 is embedded in the fork member 2065. In this embodiment, the locking block 2066 can be embedded at the end of the fork member 2065 away from the connecting plate 2064, or at the middle of the fork member 2065. If embedded in the middle of the fork member 2065, the inner wall of the pallet hole (for the insertion of the fork member 2065) should have a mating groove for the locking block 2066 to be inserted. If embedded at the end of the fork member 2065 away from the connecting plate 2064, after the fork member 2065 is fully inserted into the pallet, its end should be outside the pallet, so that when the locking block 2066 extends, it can abut against the rear end face of the pallet to limit the displacement of the pallet relative to the fork member 2065. The locking block 2066 is provided on the fork member 2065. The telescopic device (such as a miniature cylinder, electromagnetic push rod, etc.) on 065 drives the fork 2065 to extend or retract. The detection device is signal-connected to the telescopic device. Specifically, both the detection device and the telescopic device are electrically connected to an external control system. When the detection device detects that the fork 2065 has moved to a preset position, it sends a signal to the control system. The control system triggers the telescopic device to drive the locking block 2066 to extend to the outside of the fork 2065. If the locking block 2066 is embedded at the end of the fork 2065, the extended locking block 2066 acts as a limit stop against the rear edge of the pallet to prevent the pallet from sliding off along the length of the fork 2065 during handling. If the locking block 2066 is embedded in the middle of the fork 2065, the extended locking block 2066 inserts into the mating groove at the bottom of the pallet to achieve a locking connection between the pallet and the fork 2065, and also prevent the pallet from sliding off along the length of the fork 2065 during handling.

[0028] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.

The outer wall of the vertical guide rail (208) is evenly provided with locking holes (2081) for the locking blocks (2079) to be inserted along its height direction. The assembly cavity (2067) is provided with a transmission part two for the transmission connection with the locking blocks (2079). A drive gear (2071) is provided between the transmission part one and the transmission part two. The drive gear (2071) is located in the assembly cavity (2067) through a rotating device. When the rotating device drives the drive gear (2071) to rotate in a preset direction, the first transmission part drives the locking pin (2073) into the locking groove, and the second transmission part drives the locking block (2079) to disengage from the locking port (2081). When the rotating device drives the drive gear (2071) to rotate in a reset position, the first transmission part drives the locking pin (2073) to disengage from the locking groove, and the second transmission part drives the locking block (2079) into the locking port (2081).

5. The automated stacking warehouse for piston head products according to claim 4, characterized in that, The transmission part includes a toothed ring (2072) rotatably disposed in the assembly cavity (2067) and coaxial with the movable opening. The toothed ring (2072) meshes with the drive gear (2071). The toothed ring (2072) is also sleeved on the outside of the locking pin (2073). The inner wall of the toothed ring (2072) is provided with a plurality of protrusions (2074) in a ring array that correspond one-to-one with the locking pin (2073). When the rotating device drives the drive gear (2071) to rotate in a preset direction, the gear ring (2072) is driven to rotate by the drive gear (2071) so as to push the locking pin (2073) into the corresponding locking groove through the protrusion (2074).

6. The automated stacking warehouse for piston head products according to claim 4, characterized in that, The transmission unit two includes a driven rack one (2075) horizontally disposed in the assembly cavity (2067) and meshing with the drive gear (2071). A driven rack two (2076) parallel to the driven rack one (2075) is disposed at a distance from the drive gear (2071). Both driven rack one (2075) and driven rack two (2076) are slidably disposed in the assembly cavity (2067) and staggered from each other. A driven gear (2077) meshes between driven rack 1 (2075) and driven rack 2 (2076). The driven gear (2077) is rotatably disposed in the assembly cavity (2067). Each of the driven rack 1 (2075) and driven rack 2 (2076) is provided with a connecting frame at opposite ends. Each connecting frame is hinged to two sets of locking blocks (2079) on the corresponding guide slider (2063) through two sets of connecting rods (2078). When the rotating device drives the drive gear (2071) to rotate in a preset direction, the gear ring (2072) drives the driven rack one (2075) to move in the preset direction, and then the driven gear (2077) drives the driven rack two (2076) to move in the opposite direction to the driven rack one (2075), thereby driving the corresponding locking block (2079) to move into the inner cavity of the guide slider (2063) through the connecting frame and the connecting rod (2078) to disengage from the locking port (2081).

7. The automated stacking warehouse for piston head products according to claim 2, characterized in that, The support plate (2061) is provided with a detection device for detecting the position of the fork (2065). At least one locking block (2066) is embedded in the fork (2065). The locking block (2066) is driven by a telescopic device provided on the fork (2065) to extend or retract relative to the fork (2065). The detection device is signal-connected to the telescopic device. When the detection device detects that the fork (2065) has moved to a preset position, it triggers the telescopic device to drive the locking block (2066) to extend to the outside of the fork (2065).
