Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe lifting equipment technology, specifically a steel pipe lifting equipment with a locking mechanism. Background Technology
[0002] Steel pipe lifting tools are widely used in construction, petroleum, natural gas, water supply and other fields. For example, in shipbuilding companies, steel mills and construction sites, steel pipe lifting tools are used to lift and move steel pipes and cylindrical objects of various sizes.
[0003] During the hoisting of steel pipes, for thinner steel pipes, the common hoisting method is to first stack and bundle the thin steel pipes, and then directly tie them with ropes for hoisting. For steel pipes with slightly larger diameters, we often directly tie the steel pipes with ropes. However, the existing hoisting methods have the problem of having few hoisting points, which can easily lead to insufficient friction between the steel pipe and the hoisting equipment, posing a certain risk of slippage and causing safety accidents.
[0004] Therefore, a steel pipe lifting device with a locking mechanism is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a steel pipe lifting device with a locking mechanism, which can solve the problem of insufficient lifting points for steel pipe stacks, leading to easy slippage and insufficient safety after lifting.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe lifting device with a locking mechanism, comprising a connecting lifting plate, a locking assembly, and a steel pipe stack. The number of connecting lifting plates is set to multiple. The locking assembly is disposed on the connecting lifting plate, and the steel pipe stack is disposed within the locking assembly. A lifting hole is provided at the upper end of the connecting lifting plate. The locking assembly includes multiple locking blocks. A transmission hole is provided on the side wall of the connecting lifting plate. A connecting shaft is rotatably connected within the transmission hole. A drive gear is fixedly sleeved on the connecting shaft. A rotating disk is disposed on the side wall of the connecting lifting plate, and a drive gear is fixedly sleeved on the side wall of the rotating disk. The gear ring is connected to the drive gear. The side wall of the connecting plate has a placement hole and multiple guide grooves. The side walls of multiple locking blocks are fixedly connected to guide rails that match the guide grooves. The side walls of the multiple guide rails are slidably connected to the inner walls of the matching guide grooves. The upper end faces of the multiple locking blocks are fixedly connected to guide slide rods. The side wall of the rotating disk has multiple guide holes that match the guide slide rods. The side walls of the multiple guide slide rods are slidably connected to the inner walls of the matching guide holes. The center of the rotating disk has a disk hole. The steel pipe stack is placed in the disk hole and the placement hole.
[0007] Preferably, a worm gear is fixedly sleeved at the end of the connecting shaft opposite to the drive gear, and two connecting plates are fixedly connected to the back of the connecting plate. A worm is rotatably inserted into the two connecting plates, and the worm gear meshes with the worm.
[0008] Preferably, one end of the worm gear extends out of the side wall of the connecting plate and is fixedly connected to a rotary head, and the surface of the rotary head is fitted with an anti-slip sleeve.
[0009] Preferably, the upper and lower end sidewalls of the plurality of locking blocks are slidably connected to the sidewalls of the rotating disk and the connecting hanging disk.
[0010] Preferably, the lower end of the connecting plate is fixedly connected to a plate base, and the plate base is a trapezoidal block.
[0011] Preferably, the diameter of the disc hole is the same as that of the placement hole.
[0012] Preferably, the sidewalls of the rotating disk and the gear ring are slidably connected to the sidewall of the connecting hanging plate.
[0013] Compared with the prior art, this utility model provides a steel pipe lifting device with a locking mechanism, which has the following advantages:
[0014] 1.

With multiple lifting points on the steel pipe stack, its stability after being lifted is higher, making it safe and practical.
[0015] 2. The steel pipe lifting device with locking mechanism, by setting a worm gear, enables the connecting shaft to rotate under the self-locking action after the worm gear meshes, thus preventing the locking component from failing due to the lack of human intervention.

Detailed Implementation
[0024] 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.
[0025] Example:
[0026] Please see Figure 1 - Figure 7 This embodiment of a steel pipe lifting device with a locking mechanism includes a connecting lifting plate 1, a locking assembly, and a steel pipe stack 12. Multiple connecting lifting plates 1 are provided. The locking assembly is mounted on the connecting lifting plate 1, and the steel pipe stack 12 is disposed within the locking assembly. A lifting hole 2 is provided at the upper end of the connecting lifting plate 1. The locking assembly includes multiple locking blocks 9. A transmission hole 3 is provided on the side wall of the connecting lifting plate 1. A connecting shaft 4 is rotatably connected within the transmission hole 3. A drive gear 5 is fixedly sleeved on the connecting shaft 4. A rotating disk 6 is provided on the side wall of the connecting lifting plate 1, and a gear ring 7 is fixedly sleeved on the side wall of the rotating disk 6. The drive gear 5 and the gear ring... 7. Engaging connection: The side wall of the connecting plate 1 is provided with a placement hole 19 and multiple guide grooves 8. The side walls of multiple locking blocks 9 are all fixedly connected with guide rails that match the guide grooves 8. The side walls of multiple guide rails are slidably connected to the inner walls of the matching guide grooves 8. The upper end faces of multiple locking blocks 9 are all fixedly connected with guide slide rods 10. The side wall of the rotating plate 6 is provided with multiple guide holes 13 that match the guide slide rods 10. The side walls of multiple guide slide rods 10 are slidably connected to the inner walls of the matching guide holes 13. A plate hole 11 is provided at the center of the rotating plate 6. The steel pipe stack 12 is set in the plate hole 11 and the placement hole 19.
[0027] The steel pipe stack 12 is placed in the locking assembly of multiple connecting lifting plates 1. At this time, the connecting shaft 4 is controlled to drive the drive gear 5 to rotate counterclockwise, which in turn drives the rotating disk 6 to rotate clockwise through meshing with the gear ring 7. Under the clockwise rotation of the rotating disk 6, multiple guide slide rods 10 contact the inner wall of the matching guide hole 13 and drive multiple locking blocks 9 to gather towards the center of the disk hole 11, thereby locking the steel pipe stack 12 in the disk hole 11 to ensure that it will not easily slip off. The number of connecting lifting plates 1 can be determined by the staff based on the length of the steel pipe stack 12. After the steel pipe stack 12 is fixed in multiple connecting lifting plates 1 through the locking assembly, the hoist can connect to multiple lifting holes 2 through steel cables, thereby driving multiple connecting lifting plates 1 to rise and complete the lifting work of the steel pipe stack 12. This allows the steel pipe stack 12 to have multiple lifting points, thereby increasing the friction of lifting the steel pipe stack 12 to ensure that it will not slip off, making it safer and more practical.
[0028] Among them, a worm gear 15 is fixedly sleeved on one end of the connecting shaft 4 away from the drive gear 5, and two connecting plates 16 are fixedly connected to the back of the connecting plate 1. A worm 17 is rotatably inserted into the two connecting plates 16, and the worm gear 15 is meshed with the worm 17.
[0029] By setting up a worm gear 15, a worm 17, and two connecting plates 16, the operator can control the worm 17 to rotate when the connecting shaft 4 needs to be rotated. Then, through the meshing of the worm 17 and the worm gear 15, the rotation control of the connecting shaft 4 can be achieved on the back of the connecting hanging plate 1. Because the worm gear 15 and the worm 17 have self-locking properties after meshing, the self-rotation of the connecting shaft 4 without human intervention can be effectively prevented.
[0030] One end of the worm gear 17 extends out of the side wall of the connecting plate 16 and is fixedly connected to a rotary head 18, and an anti-slip sleeve is fitted on the surface of the rotary head 18.
[0031] By setting up a rotary head 18 and an anti-slip sleeve, the rotary head 18 makes it easier for the operator to rotate the worm gear 17, and the anti-slip sleeve helps to increase the friction between the fingers and the surface of one end of the worm gear 17, thus preventing slippage.
[0032] Among them, the upper and lower end sidewalls of multiple locking blocks 9 are slidably connected to the sidewalls of the rotating disk 6 and the connecting hanging disk 1;
[0033] By making the upper and lower end sidewalls of the multiple locking blocks 9 slidably connected to the sidewalls of the rotating disk 6 and the connecting hanging plate 1, the upper and lower end of the multiple locking blocks 9 can slide along the sidewalls of the rotating disk 6 and the connecting hanging plate 1 respectively.
[0034] Among them, the lower end of the connecting plate 1 is fixedly connected to the plate base 14, and the plate base 14 is a trapezoidal block;
[0035] By setting up the hanging plate base 14, the connecting hanging plate 1 can be stably placed on the ground and wait for the steel pipe stack 12 to be placed.
[0036] The diameter of the disc hole 11 is the same as that of the placement hole 19;
[0037] By making the diameter of the disc hole 11 the same as that of the placement hole 19, the cross-sectional dimensions of the steel pipe stack 12 that can be placed in the disc hole 11 and the placement hole 19 are the same, thus avoiding the situation where the disc hole 11 can be put into the steel pipe stack 12, but the front end of the steel pipe stack 12 cannot extend out of the placement hole 19.
[0038] The side walls of the rotating disk 6 and the toothed ring 7 are slidably connected to the side wall of the connecting hanging plate 1.
[0039] By making the sidewalls of both the rotating disk 6 and the toothed ring 7 slidably connected to the sidewall of the connecting hanging plate 1, the sidewalls of both the rotating disk 6 and the toothed ring 7 can slide along the sidewall of the connecting hanging plate 1.
[0040] The working principle of the above embodiment is as follows: the steel pipe stack 12 is placed in the locking assembly of multiple connecting lifting plates 1. At this time, the connecting shaft 4 is controlled to drive the drive gear 5 to rotate counterclockwise, and then through the meshing with the gear ring 7, it drives the rotating disk 6 to rotate clockwise. Under the clockwise rotation of the rotating disk 6, multiple guide slide rods 10 contact the inner wall of the matching guide hole 13 and drive multiple locking blocks 9 to gather towards the center of the disk hole 11, thereby locking the steel pipe stack 12 in the disk hole 11 to ensure that it will not easily slip off. The number of connecting lifting plates 1 can be determined by the staff according to the length of the steel pipe stack 12. After the steel pipe stack 12 is fixed in multiple connecting lifting plates 1 through the locking assembly, the hoist can connect to multiple lifting holes 2 through steel cables, thereby driving multiple connecting lifting plates 1 to rise and complete the lifting work of the steel pipe stack 12. This allows the steel pipe stack 12 to have multiple lifting points, thereby increasing the friction of lifting the steel pipe stack 12 to ensure that it will not slip off, making it safer and more practical.
