DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1: A first mounting frame 1 is respectively installed at both ends of one side of the limit frame 14, a cavity 16 is opened inside the first mounting frame 1, a second double-threaded rod 15 and a supporting slide bar 19 are installed inside the cavity 16, a hydraulic lifting rod 3 is respectively installed on both sides of the top of the first mounting frame 1, a second mounting frame 7 is installed on the top of the hydraulic lifting rod 3, a first double-threaded rod 5 is installed inside the second mounting frame 7, a placing table 8 is installed on the top of the second mounting frame 7, a limit slider 23 is sleeved on the outer side of the supporting slide bar 19, a limit rod 24 is installed on one side of the limit slider 23, a spring 20 is sleeved on the outer side of the supporting slide bar 19, and the top view of the mounting structure of the first mounting frame 1 and the limit frame 14 is in a concave shape.

[0022] Specifically, Figure 1 , Figure 2 and Figure 4As shown, since a first mounting frame 1 is installed at each of the two ends of one side of the limit frame 14, and the top view of the mounting structure of the two first mounting frames 1 and the limit frame 14 is in a concave shape, when the crane accessories are transported by the device, the device can be moved above the maintenance platform so that the maintenance platform is located between the two first mounting frames 1. Since a limiting rod 24 is also movably installed between the two first mounting frames 1, the limiting rod 24 can ensure that the two first mounting frames 1 will not be deformed during the movement. At the same time, when the device is moved, the bottom end of the maintenance platform will squeeze the limiting rod 24 to move the limiting rod 24 toward the direction of the limit frame 14. Since the limiting sliders 23 installed at both ends of the limiting rod 24 are slidably sleeved on the outside of the supporting slide bar 19, the limiting slider 23 will move toward the limit frame 14 along the installation direction of the supporting slide bar 19, and at the same time squeeze the supporting slide bar 1 9. The spring 20 on the outside, when the device is separated from the maintenance platform, the squeezed spring 20 will rebound immediately, so that the limit rod 24 moves to the initial position. Since the bottom end of the second mounting frame 7 is installed with a hydraulic lifting rod 3, the height of the second mounting frame 7 can be lowered by contracting the output end of the hydraulic lifting rod 3, so that it is convenient for workers to carry the crane accessories to the top of the second mounting frame 7. Subsequently, the height of the second mounting frame 7 can be increased by extending the output end of the hydraulic lifting rod 3. Therefore, during the movement of the transfer device, the crane accessories placed above the second mounting frame 7 will not collide with the maintenance platform. Subsequently, the output end of the hydraulic lifting rod 3 can be contracted again to place the crane accessories above the maintenance platform. In this process, the operation of manually carrying the crane accessories onto the maintenance platform is avoided, the labor intensity of the workers is reduced, and the personal safety of the workers is guaranteed during the transportation process.

[0023] A control rod 13 is installed at the top of the limit frame 14, and a pull rod 11 is installed at the top of the limit frame 14, a power supply device is installed inside the limit frame 14, and a base 18 is installed at the bottom of the first mounting frame 1, a motor 2 is movably installed inside the base 18, and a brake plate 22 is installed on one side of the base 18, and the brake plate 22 is used in conjunction with the pulley 21, a motor 2 is installed at one end of the first mounting frame 1, and the output end of the motor 2 is connected to one end of the second double-threaded screw rod 15, and a second threaded slider 17 is respectively sleeved on the outer sides of both ends of the second double-threaded screw rod 15, and The top end of the second threaded slider 17 extends out of the cavity 16, the top end of the second threaded slider 17 is hinged with a support rod 12, and the top end of the support rod 12 is hinged to the bottom end of the second mounting frame 7, a hand wheel 4 is installed at one end of the second mounting frame 7, and the output end of the hand wheel 4 is connected to one end of the first double-threaded rod 5, a first threaded slider 6 is respectively sleeved on the outer sides of both ends of the first double-threaded rod 5, and the top end of the first threaded slider 6 extends out of the second mounting frame 7, a splint 10 is installed at the top of the second mounting frame 7, and an anti-slip pad 9 is installed on one side of the splint 10.

[0024] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the rotation of the second double-corrugated screw 15 can be controlled by the rotation of the output end of the motor 2, and the two second threaded sliders 17 can slide relative to each other through the rotation of the second double-corrugated screw 15. When the output end of the hydraulic lifting rod 3 begins to extend and retract, the output end of the motor 2 will also begin to rotate in response, thereby driving the two second threaded sliders 17 to slide relative to each other along the installation direction of the second double-corrugated screw 15, thereby changing the height of the support rod 12, ensuring that the second mounting frame 7 can be lifted and lowered normally while providing stable support for it. The first double-corrugated screw 5 can be driven to rotate by rotating the hand wheel 4, and the two first threaded sliders 6 can slide relative to each other along the installation direction of the first double-corrugated screw 5 through the rotation of the first double-corrugated screw 5, and at the same time drive the anti-slip pad 9 installed on one side of the splint 10 to clamp the two sides of the crane accessories placed on the placement table 8, thereby ensuring that the accessories will not fall during transportation.

[0025] Working principle: When in use, the height of the second mounting frame 7 is lowered by contracting the output end of the hydraulic lifting rod 3 and rotating the output end of the motor 2, and then the crane accessories are moved to the top of the placement table 8. Then, the first double-threaded screw 5 can be driven to rotate by rotating the hand wheel 4. The rotation of the first double-threaded screw 5 can make the two first threaded sliders 6 slide relatively along the installation direction of the first double-threaded screw 5, and at the same time drive the anti-slip pad 9 installed on one side of the clamping plate 10 to clamp the two sides of the crane accessories placed on the placement table 8, so as to ensure that the accessories will not fall during the transportation process. Subsequently, the height of the second mounting frame 7 is increased by rotating the output end of the hydraulic lifting rod 3 and reverse rotation of the output end of the motor 2, and the entire device together with the crane accessories are moved to the top of the maintenance platform through the pulley 21 installed at the bottom end of the base 18, so that the maintenance platform is located between the two first mounting frames 1, and the clamps 10 on both sides of the placement table 8 are released from clamping the accessories by rotating the hand wheel 4 in the opposite direction. Finally, the height of the second mounting frame 7 is lowered by contracting the output end of the hydraulic lifting rod 3 and rotating the output end of the motor 2 in the forward direction, so that the crane accessories are placed on the maintenance platform, and the entire device can be removed.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
