Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Referring to Figures 1-3 , a hoisting mechanism that is convenient for fixing includes a base 1 and a hoister 4. Two slide rails 2 are fixedly arranged above the base 1, and the two slide rails 2 are arranged in parallel. That is, two mutually parallel slide rails are arranged on the upper surface of the base 1 along the length direction of the base 1; an installation bracket 3 is installed on the two slide rails 2. Specifically, a chute that is matched with the slide rail is arranged at the bottom of the installation bracket 3.

[0024] The hoist 4 is fixedly installed on the lower side wall of the middle section of the mounting frame 3. The output end of the hoist 4 is fixedly connected to a steel wire rope 5, and the other end of the steel wire rope 5 is fixedly connected to a connecting plate 6. Two pull rods 7 are fixedly connected to the lower side wall of the connecting plate 6. The two pull rods 7 are symmetrically arranged and vertically arranged. The other end of the pull rod 7 is fixedly connected to a fixed shaft 20, and the other end of the fixed shaft 20 is fixedly connected to a rounded head 22. The free end face of the rounded head 22 is provided with a rounded corner, and a tip protruding upward is provided at the part between the rounded head and the fixed shaft 20. A moving ring 21 is slidably sleeved on the fixed shaft 20. The lower side wall of the moving ring 21 is matched with the tip shape of the rounded head 22, and the upper side wall of the moving ring 21 is inclined. The upper side wall of the moving ring 21 is fixedly connected to the lower end of the pull rod 7 through a magnetic attraction device;

[0025] The magnetic attraction device includes a first installation groove opened at the top of the moving ring 21, and a first magnetic ring 23 is fixedly embedded in the first installation groove. A second installation groove is opened at the bottom of the pull rod 7, and a second magnetic ring 24 is fixedly embedded in the second installation groove. The first magnetic ring 23 and the second magnetic ring 24 are arranged with opposite magnetic poles, so that an attractive force can be generated between the two magnetic rings. The openings of the first installation groove and the second installation groove are arranged opposite to each other, and their shapes and sizes are adapted to the outer shape of the magnetic ring. This setting enables the connection between the moving ring 21 and the pull rod 7 to be released at any time and automatically suck together after release, ensuring the functionality and continuous utilization of the equipment. Rubber gaskets are fixedly bonded to the opposite side walls of the first magnetic ring 23 and the second magnetic ring 24. This setting provides buffering when the first magnetic ring 23 and the second magnetic ring 24 are attracted to each other, preventing the first magnetic ring 23 and the second magnetic ring 24 from coming into hard contact, resulting in part breakage, reducing the possibility of equipment damage, and increasing the practicality of the equipment.

[0026] A load-carrying plate 8 is placed on the base 1, and the load-carrying plate 8 has a placement area. An equipment 9 is placed in the placement area. Two connecting pipes 10 are respectively threadedly connected to both ends of the load-carrying plate 8. A sliding groove 13 is opened on the inner wall of the connecting pipe 10, and a convex block 14 is fixedly connected to the side wall of the support plate 11, and the convex block 14 is slidably embedded in the sliding groove 13. Specifically, a sliding groove 13 is opened on the pipe wall of the connecting pipe 10 extending from the pipe orifice to the inside. The outside of the support plate 11 is welded with a convex block 14 that slidably cooperates with the sliding groove 13. At the same time, the outer peripheral wall of the support plate 11 slidably cooperates with the pipe wall of the connecting pipe 10. This setting enables the support plate 11 not to rotate in the connecting pipe 10, playing a role in protecting the first spring 12 and increasing the service life of the first spring 12.

[0027] A pallet 11 is slidably connected inside the connecting pipe 10, and the bottom of the pallet 11 is fixedly connected to the bottom of the connecting pipe 10 through a first spring 12. A cavity 15 is formed in the side wall of the connecting pipe 10, and two sliding rods are fixedly connected in the cavity 15. A second spring 16 is sleeved on the two sliding rods. One end of the second spring 16 is fixedly connected to the side wall of the cavity 15, and the other end of the second spring 16 is fixedly connected to a slider 17. The slider 17 is slidably sleeved on the sliding rod. A locking tongue 18 is fixedly connected between the two sliders 17. The upper side wall of the locking tongue 18 is inclined, and the lower side wall of the locking tongue 18 is horizontal. This setting enables the locking tongue 18 to be clamped with the rounded head 22 and to be disengaged from the connecting pipe 10 under the action of the moving ring 21, so as to achieve the functions of convenient fixing and disassembly.

[0028] The locking tongue 18 penetrates through the side wall of the cavity 15 and extends into the connecting pipe 10. A sealing cover 19 is fixedly connected to the bottom of the cavity 15. A trolley 25 is placed on the base 1, and the trolley 25 is located between the two slide rails 2. A buffer pad is fixedly installed on the upper side wall of the trolley 25. This setting enables the device 9 to be placed on the trolley 25 and move along with the trolley 25. Moreover, during the placement process, the buffer pad can protect the device 9 from being damaged, increasing the safety of the device.

[0029] In the present utility model, when it is necessary to lift the device 9 placed on the loading plate 8, the hoist 4 is started to move the connecting plate 6 downward, so that the pull rod 7 moves downward synchronously. Then, the bottom of the pull rod 7 is aligned with the connecting pipe 10, and the steel wire rope 5 is continuously released, so that the pull rod 7 is inserted into the connecting pipe 10 under the action of gravity. Then, the rounded head 22 will push the locking tongue 18 into the cavity 15. When the rounded head 22 completely enters the connecting pipe 10, the locking tongue 18 is reset under the action of the second spring 16 and clamps the rounded head 22. At this time, the hoist 4 can be used to lift the pull rod 7, and the loading plate 8 will be lifted synchronously, so that the device 9 can be lifted. When it is necessary to lower the loading plate 8, the connecting plate 6 can be released downward, so that the loading plate 8 contacts the upper end of the trolley 25. The connecting plate 6 is continuously lowered, and the pull rod 7 and the connecting plate 6 move downward under the action of gravity. At this time, the locking tongue 18 contacts the moving ring 21. Under the action of the moving ring 21, the locking tongue 18 retracts into the cavity 15 and is ejected again by the second spring 16 above the moving ring 21. Then, the hoist 4 lifts the pull rod 7, and the locking tongue 18 will drive the moving ring 21 to move downward until the moving ring 21 contacts the rounded head 22. Under the action of the upper side wall of the moving ring 21, the locking tongue 18 enters the cavity 15 again. At this time, the moving ring 21 and the rounded head 22 are disengaged from the connecting pipe 10, and then the locking tongue 18 is reset. At the same time, under the action of the first magnetic ring 23 and the second magnetic ring 24, the moving ring 21 moves upward and contacts the bottom of the pull rod 7, and then the next handling can be continued. The fixing and disengagement of the pull rod 7 and the connecting pipe 10 are very convenient, greatly shortening the handling time and increasing the work efficiency.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
