Description

Technical Field

[0001] This invention relates to the field of transfer equipment technology, and in particular to a transfer device based on a locking guide post. Background Technology

[0002] In existing technologies, some transfer equipment often uses guide columns and guide grooves as fixed devices to achieve trajectory control. However, in special applications such as ships, to prevent the transfer equipment from tilting or shifting due to the ship's rolling, it is required that the transfer equipment can be easily locked in the event of loss of power or stop. This requires the guide columns to be confined to a fixed track during operation. However, guide columns usually only have a guiding function and cannot lock. Summary of the Invention

[0003] In response to the shortcomings of the existing production technology, the applicant provides a transfer device based on a locking guide post, which enables the transfer device to have a guiding function and can also cooperate with the guide rail to achieve automatic locking.

[0004] The technical solution adopted in this invention is as follows: A transfer device based on locking guide posts includes a transfer tray, a welded mounting plate is provided at the bottom of the transfer tray, and guide posts are assembled on the welded mounting plate. The guide posts are arranged in a guide rail. The guide rail has the following structure: it includes a U-shaped groove, and a track is laid in the U-shaped groove. The track has a continuous concave-convex structure, and the track contacts and cooperates with the bottom of the guide post. The bottom of the guide post is provided with a sliding locking pin that extends and retracts within the guide post. The sliding locking pin passes through the bottom surface of the guide post and extends outward. The bottom of the sliding locking pin includes a side plane for parallel contact with the side of the track and an inclined plane for sliding contact with the inclined surface of the track. Multiple guide posts are arranged along the length direction within the track, and the installation orientation of adjacent guide posts is rotated by 90°.

[0005] As a further improvement to the above technical solution:

[0006] Preferably, the side wall of the transfer pallet is provided with a hook for connecting to the power equipment.

[0007] Preferably, the guide post has the following structure: it includes a rocker arm, the inner ring of which is fixedly connected to the outer wall of the rotating sleeve. A "︶"-shaped guide hole is provided on the rotating sleeve, and a headless stud is installed within the guide hole. The headless stud is mounted on both sides of the lifting sleeve. The lifting sleeve is connected to the top of the sliding locking pin. A clamping sleeve is provided at the bottom of the lifting sleeve, and a compression spring is provided at the bottom of the clamping sleeve. The other end of the compression spring is abutted by the sliding locking pin. When the rocker arm rotates the rotating sleeve, the headless stud is lifted within the "︶"-shaped guide hole. The lifting of the headless stud causes the lifting sleeve to rise, and the lifting sleeve causes the sliding locking pin at the bottom to retract axially along the guide hollow axis. When the rocker arm resets the rotating sleeve, the headless stud descends within the "︶"-shaped guide hole. The descent of the headless stud causes the lifting sleeve to move downwards, and the reaction force of the compression spring causes the sliding locking pin to extend axially along the guide hollow axis.

[0008] Preferably, a needle roller bearing is sleeved on the bottom periphery of the guide hollow shaft, and a push-pull ball bearing is provided on the top periphery of the guide hollow shaft.

[0009] Preferably, the bottom surface of the guide hollow shaft is fixed with a lower end cap.

[0010] Preferably, an upper end cover is provided on the top of the compression sleeve, and the upper end cover compresses the compression spring through the compression sleeve.

[0011] Preferably, at least one adjusting shim is also provided between the clamping sleeve and the upper end cover.

[0012] Preferably, a graphite copper sleeve is provided on the inner wall of the rotating sleeve, and a groove is formed on the graphite copper sleeve that matches the guide hole on the rotating sleeve.

[0013] Preferably, a screw assembly is also provided at the top of the lifting sleeve.

[0014] Preferably, the outer wall of the U-shaped groove is evenly distributed with multiple reinforcing support members along the length direction, and the structure of a single reinforcing support member is a plate-shaped support.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention features a compact structure. By adding a welded mounting plate to the bottom of the transfer pallet and assembling guide posts on the plate, the guide posts engage with the guide rail, allowing the transfer pallet to move along the length of the guide rail. Simultaneously, multiple guide posts are arranged along the length of the rail, with adjacent guide posts having a 90° rotational mounting position. Under normal conditions, all guide posts within the rail have their sliding locking pins extended downwards under the action of internal compression springs. The mounting position of some guide posts ensures that the side plane of their sliding locking pins is parallel to and abuts against the side plane of the rail, locking the transfer device. To unlock, simply rotate the abutting pins... The rocker arm of some guide posts causes their headless studs to rise along the guide hole on the rotating sleeve. The headless studs drive the sliding locking pins upward through the lifting sleeve. At this time, the remaining sliding locking pins are still in the extended state and the inclined plane of the sliding locking pins slides in contact with the inclined plane of the track. When the transfer tray is pulled and moved horizontally on the guide rail, the sliding locking pins extend and retract vertically in the vertical direction under the vertical force of the track and the force of the internal compression spring. This invention realizes the locking and unlocking functions of the transfer device through the cooperation of the guide posts and the guide rail. It can be used in special working conditions such as ship turbulence and has a wide range of applications. Attached Figure Description

[0032] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0033] like Figures 1 to 11 As shown, the transfer device based on locking guide posts in this embodiment includes a transfer tray 1, a welded mounting plate 5 at the bottom of the transfer tray 1, and guide posts 3 mounted on the welded mounting plate 5. The guide posts 3 are located inside a guide rail 4. The guide rail 4 has the following structure: it includes a U-shaped groove 401, and a track 402 is laid inside the U-shaped groove 401. The track 402 has a continuous concave-convex structure, and the track 402 contacts and engages with the bottom of the guide post 3. The bottom of the guide post 3 is provided with a sliding locking pin 309 that extends and retracts inside the guide post 3. The sliding locking pin 309 penetrates the bottom surface of the guide post 3 and extends out. The bottom of the sliding locking pin 309 includes a side plane 30901 for parallel contact with the side of the track 402 and an inclined plane 30902 for sliding contact with the inclined surface of the track 402. Multiple guide posts 3 are arranged along the length direction inside the track 402, and adjacent guide posts 3 are arranged with a 90° rotational mounting orientation.

[0034] In this embodiment, the side wall of the transfer tray 1 is provided with a hook 2 for connecting to the power equipment.

[0035] In this embodiment, the guide post 3 has the following structure: it includes a rocker arm 301, the inner ring of which is fixedly connected to the outer wall of the rotating sleeve 307. A “︶”-shaped guide hole is provided on the rotating sleeve 307, and a headless stud 303 is installed in the guide hole. The headless stud 303 is assembled on both sides of the lifting sleeve 312. The lifting sleeve 312 is connected to the top of the sliding locking pin 309. A clamping sleeve 311 is provided at the bottom of the lifting sleeve 312, and a compression spring 310 is provided at the bottom of the clamping sleeve 311. The other end of the compression spring 310 is abutted by the sliding locking pin 309. When the rotating sleeve 307 is rotated, the headless stud 303 is raised in the “︶”-shaped guide hole. When the headless stud 303 is raised, it drives the lifting sleeve 312 to rise. The lifting sleeve 312 drives the sliding locking pin 309 at the bottom to retract inward along the guide hollow shaft 304. When the rocker arm 301 resets the rotating sleeve 307, the headless stud 303 descends in the “︶”-shaped guide hole. When the headless stud 303 descends, it drives the lifting sleeve 312 to move downward and, through the reaction force of the compression spring 310, causes the sliding locking pin 309 to extend outward along the guide hollow shaft 304.

[0036] In practical applications, for example, three guide posts 3 can be installed within a guide rail 4. The guide posts 3 on both sides are installed vertically so that the inclined plane 30902 of the sliding locking pin 309 slides and engages with the inclined surface of the rail 402. The guide post 3 in the middle position is rotated 90° to be installed horizontally so that the side plane 30901 of the sliding locking pin 309 of the middle guide post 3 is parallel and abuts against the side of the rail 402. When locking is required, simply extend the sliding locking pin 309 of the middle guide post 3 to abut against the side of the rail 402 to achieve locking. During normal transport... Rotating the rocker arm 301 of the guide post 3 in the middle position causes the headless stud 303 to rise in the guide hole. The headless stud 303 drives the lifting sleeve 312, which causes the sliding locking pin 309 to retract into the guide post 3 along the direction of the guide hollow shaft 304. At this time, the inclined plane 30902 of the guide posts 3 on both sides cooperates with the inclined surface of the track 402. Under the vertical force of the inclined surface of the track 402 and the action of the compression spring 310 inside the guide post 3, the sliding locking pin 309 of the guide posts 3 on both sides slides up and down in the vertical direction, driving the transfer tray 1 to operate along the direction of the guide rail 4.

[0037] In this embodiment, an upper end cover 302 is provided on the top of the clamping sleeve 311, and the upper end cover 302 presses the compression spring 310 through the clamping sleeve 311; at least one adjusting shim 315 is also provided between the clamping sleeve 311 and the upper end cover 302, at which time the compression spring 310 has a certain preload force, which can be adjusted by increasing or decreasing the number of adjusting shims 315.

[0038] In this embodiment, a needle roller bearing 305 is sleeved on the bottom periphery of the guide hollow shaft 304, and a push-pull ball bearing 306 is provided on the top periphery of the guide hollow shaft 304. A lower end cap 308 is fixed to the bottom surface of the guide hollow shaft 304. A graphite copper sleeve 313 is matched and provided on the inner side wall of the rotating sleeve 307. A groove matching the guide hole on the rotating sleeve 307 is formed on the graphite copper sleeve 313. The push-pull ball bearing 306 and the graphite copper sleeve 313 help to reduce the axial and radial frictional forces of the rotating sleeve 307 during the rotation and lifting process, and reduce frictional damage. The lower end cap 308 is used to fix the needle roller bearing 305.

[0039] In this embodiment, a screw assembly 314 is also provided on the top of the lifting sleeve 312.

[0040] In this embodiment, multiple reinforcing support members 403 are evenly distributed along the length of the outer wall of the U-shaped groove 401, and the structure of a single reinforcing support member 403 is a plate-shaped support.

[0041] like Figures 9-11 As shown, in this embodiment, the structure of the present invention is reasonable. A welding mounting plate 5 is added to the bottom of the transfer pallet 1 and a guide column 3 is assembled on the welding mounting plate 5 so that the guide column 3 cooperates with the guide rail 4 and the transfer pallet 1 moves along the length direction of the guide rail 4.

[0042] like Figure 10 The image shows the locked state. Since the installation orientation between adjacent guide posts 3 is set to rotate 90°, and all guide posts 3 in the guide rail 4 extend outward under the action of the internal compression spring 310, at this time, due to their specific installation orientation, some of the guide posts 3 will cause the side plane 30901 of the sliding locking pin 309 to be parallel and abut against the side of the rail 402, thus locking the transfer device.

[0043] like Figure 11 As shown, when unlocking is required, only the rocker arm 301 of the opposing guide post 3 needs to be rotated, causing their headless studs 303 to rise along the guide hole on the rotating sleeve 307. The headless studs 303 drive the sliding locking pin 309 upward through the lifting sleeve 312, and the sliding locking pin 309 enters the interior of the guide post 3, releasing the locking state. At this time, the sliding locking pins 309 of the remaining guide posts 3 are still in the extended state, and the inclined plane 30902 slides with the inclined surface of the track 402. The transfer tray 1 can be pulled and moved horizontally on the guide rail 4. In the horizontal state, the sliding locking pin 309 extends and retracts vertically under the vertical force of the track 402 and the force of the compression spring 310 inside itself. For example, the rotation of the rocker arm 301 can be powered by a cylinder to provide the power for the rotation direction.

[0044] This invention achieves the locking and unlocking functions of the transfer device through the cooperation of the guide column 3 and the guide rail 4, and can be used in special working conditions such as ship turbulence, with a wide range of applications.
