Manual handling is time-consuming and labor-intensive, so overhead cranes are generally used to complete the transportation. Hydraulic cylinders are an indispensable component of overhead cranes, and there are various styles of overhead crane anode hydraulic cylinders on the market to meet different requirements.

[0003] However, in general multi-functional overhead crane anode cylinders, the shaft pin may move out of place, causing the lower shaft pin to fall off and the anode to fall. Furthermore, it is inconvenient to clamp the anode for transfer and disassemble the cylinder. Therefore, we propose a multi-functional overhead crane anode cylinder that prevents the lower shaft pin from falling off, in order to solve the problems mentioned above. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional overhead crane anode cylinder for preventing the lower end shaft pin from falling off, comprising: a cylinder body, an output shaft installed at the lower end of the cylinder body for lifting, and a first limiting plate engaged with the rear end of the cylinder body;

[0006] Also includes:

[0007] The lower end of the output shaft is bolted to a shaft pin body, and the left and right sides and the lower side of the shaft pin body are respectively provided with an anti-detachment structure and a clamping structure. The anti-detachment structure includes a mounting block, a screw, a baffle and a mounting rod, and the clamping structure includes a bearing plate, a connecting shaft, a worm gear, a worm, a motor, a connecting arm and a clamping component.

[0008] The first limiting plate has limiting rods fixedly connected to both its left and right ends, and the limiting rods are nested in the hollow structure of the connecting ear, and the front end of the limiting rods is threadedly connected to a limiting round cover.

[0009] Preferably, the mounting blocks are symmetrically embedded and connected to the lower end of the output shaft, and the lower end of the mounting blocks is fixedly connected to a screw, which is nested in the left and right ends of the baffle, and the lower end of the screw is threaded with a nut.

[0010] Preferably, a mounting rod is engaged within the hollow structure in the middle of the baffle, and the upper end of the mounting rod is fixedly connected to the lower end of the shaft pin body, wherein the diameter of the shaft pin body is smaller than the diameter of the hollow structure of the baffle, and a bearing plate is fixedly connected to the lower end of the mounting rod.

[0011] Preferably, the lower front end of the bearing plate is symmetrically rotatably connected to a connecting shaft, and the lower end of the connecting shaft is fixedly connected to a worm gear, and the inner ends of the two sets of worm gears are meshed with the worm.

[0014] Preferably, the connecting ears are symmetrically fixedly connected to the second limiting plate, and the second limiting plate is engaged with the front end of the cylinder body, and the height of the second limiting plate is equal to the distance between the upper and lower ends of the cylinder body.

[0016] 1. It is equipped with a screw and a baffle. The diameter of the shaft pin body is smaller than the diameter of the hollow structure of the baffle, so that the shaft pin body will not slide up and down in the hollow structure of the baffle.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a multi-functional overhead crane anode cylinder for preventing the lower end shaft pin from falling off, comprising a cylinder body 1, an output shaft 2, a mounting block 3, a screw 4, a baffle 5, a shaft pin body 6, a mounting rod 7, a bearing plate 8, a connecting shaft 9, a worm gear 10, a worm 11, a motor 12, a connecting arm 13, a clamping component 14, an anode body 15, a first limiting plate 16, a limiting rod 17, a connecting ear 18, a second limiting plate 19, and a limiting round cover 20. When using this multi-functional overhead crane anode cylinder for preventing the lower end shaft pin from falling off, if... Figure 1 , Figure 3 and Figure 4 Since the limiting rod 17 is nested in the hollow structure of the connecting ear 18, the front end of the limiting rod 17 is threadedly connected to the limiting round cover 20, and the height of the second limiting plate 19 is equal to the distance between the upper and lower ends of the cylinder body 1.

[0027] Therefore, the first limiting plate 16 is fixedly connected to the overhead crane, the rear end of the cylinder body 1 is engaged with the first limiting plate 16, the second limiting plate 19 is placed on the front side of the cylinder body 1, the second limiting plate 19 is pushed so that the hollow structure of the symmetrically arranged connecting ears 18 is nested and connected to the limiting rod 17 at the corresponding position, so that the second limiting plate 19 is engaged with the front end of the cylinder body 1, and the limiting round cover 20 is rotated so that it is threadedly connected to the front end of the limiting rod 17.

[0028] The position of the second limiting plate 19 is limited by the limiting rod 17 and the limiting round cover 20. The position of the cylinder body 1 on the crane is limited by the first limiting plate 16 and the second limiting plate 19. When disassembling, simply rotate the limiting round cover 20 to disengage it from the limiting rod 17, pull the second limiting plate 19 forward to disengage the connecting ear 18 from the limiting rod 17, and take the cylinder body 1 out from the inside of the first limiting plate 16, thus facilitating the disassembly and assembly of the cylinder body 1.

[0029] like Figure 1 , Figure 4 and Figure 5 The anti-detachment structure includes a mounting block 3, a screw 4, a baffle 5, and a mounting rod 7. The mounting block 3 is symmetrically embedded and connected to the lower end of the output shaft 2. The lower end of the screw 4 is threaded with a nut. The diameter of the shaft pin body 6 is smaller than the diameter of the hollow structure of the baffle 5.

[0030] Therefore, after the shaft pin body 6 is bolted to the lower end of the output shaft 2, the left and right ends of the baffle 5 are nested and connected to the screw 4 that needs to be symmetrically arranged. The nut is rotated so that it is threaded to the lower end of the screw 4. The baffle 5 is installed by the mounting block 3 and the screw 4. The mounting rod 7 is engaged in the hollow part of the baffle 5. The shaft pin body 6 will not move up or down in the hollow structure of the baffle 5. The baffle 5 plays a role in the reaction force, which effectively avoids the anode body 15 from falling due to the shaft pin body 6 moving out and reduces the workload of maintenance personnel, thereby preventing the lower shaft pin body 6 from falling out and causing the anode body 15 to fall.

[0031] like Figure 1 , Figure 2 and Figure 4 The clamping structure includes a bearing plate 8, a connecting shaft 9, a worm gear 10, a worm 11, a motor 12, a connecting arm 13, and a clamping member 14. Since the inner ends of the left and right sets of worm gears 10 are meshed and connected to the worm 11, the inner diameter of the annular structure formed by the left and right sets of clamping members 14 is equal to the upper diameter of the anode body 15. The clamping member 14 rotates on the underside of the bearing plate 8 through the worm gears 10 and the worm 11.

[0032] Therefore, when it is necessary to clamp the anode body 15, the motor 12 is made to drive the worm gear 11 to rotate at the lower end of the bearing plate 8. When the worm gear 11 rotates, it meshes with the two sets of worm wheels 10 on the left and right sides, so that the connecting shafts 9 arranged symmetrically on the left and right sides rotate at the lower end of the bearing plate 8. The worm gear 11 drives the two sets of connecting arms 13 to rotate inward.

[0033] The clamping members 14, which are symmetrically arranged on the left and right, are brought closer to each other until the inner walls of the two sets of clamping members 14 are tightly attached to the upper outer wall of the anode body 15, so that the clamping members 14 limit the anode body 15, thereby facilitating the clamping and transfer of the anode body 15. All the electrical components mentioned above are existing technologies and will not be described in detail here.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
