Description

Technical Field

[0001] This utility model relates to the field of crane equipment technology, and in particular to an adjustable base for cranes. Background Technology

[0002] Cranes are widely used as important mechanical equipment in modern engineering construction, cargo loading and unloading, and other fields. The crane base is a key component that bears the weight and load of the entire crane, and its performance directly affects the stability, safety and operating efficiency of the crane.

[0003] Traditional crane bases are inconvenient to adjust in terms of working direction, often requiring the entire crane to be moved to change the working angle. This is not only time-consuming and labor-intensive, but may also affect the crane's lifespan and accuracy due to frequent movements. In addition, traditional bases also have limitations in terms of movement and fixation. They are not flexible and convenient to move, and are difficult to install quickly and securely, failing to meet the needs of diverse operating scenarios. Therefore, we propose an adjustable crane base to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable base for cranes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable base for a crane includes: a base, a controller on one side of the base, four sets of support columns fixedly installed at the bottom of the base, a rotating shaft and a worm gear rotatably installed inside the base, a worm wheel fixedly installed on the outer side of the rotating shaft, a worktable fixedly installed on the top of the rotating shaft, a rotating ring fixedly installed at the bottom of the worktable, a rotating seat fixedly installed on the top of the base, a support plate fixedly installed at the bottom of the base, a hydraulic cylinder fixedly installed on one side of the support plate, two sets of inclined blocks slidably installed at the bottom of the base, a connecting block fixedly installed between the two sets of inclined blocks, four sets of lifting rods fixedly installed at the bottom of the two sets of bases, a base plate fixedly installed at the bottom of the four sets of lifting rods, four sets of moving wheels provided at the bottom of the base plate, and two sets of inclined blocks fixedly installed on the top of the base plate.

[0007] Preferably, four sets of fastening bolts are movably inserted into the bottom of each of the four sets of support columns. The rotating ring is rotatably installed in the rotating seat. One side of one set of inclined blocks is fixedly installed on the output end of the hydraulic cylinder, and the two sets of inclined blocks are slidably installed on one side of the corresponding inclined blocks.

[0008] Preferably, a drive motor is fixedly installed on one side of the base, and one end of the worm gear is fixedly installed on the output end of the drive motor.

[0009] Preferably, the worm gear meshes with the worm, and the worm gear is disposed inside the base.

[0010] Preferably, the bottom of the base is provided with a sliding groove, and the two sets of inclined blocks are slidably installed in the sliding groove.

[0011] Preferably, the inclined surfaces of both sets of inclined blocks two are provided with inclined grooves, and the two sets of inclined blocks one are slidably installed in the corresponding inclined grooves.

[0012] In this utility model, an adjustable base for a crane is provided, which stabilizes the worktable angle by setting a rotating ring and a rotating base, and ensures the stability of the device on the ground by setting fastening bolts at the bottom of the support column.

[0013] This utility model features a rational structural design. By coordinating a drive motor, worm gear, worm wheel, and rotating shaft, the angle of the worktable is stabilized and can be self-lockingly adjusted at any angle. Through the interaction of a hydraulic cylinder, support, inclined block one, connecting block, inclined block two, inclined groove, sliding groove, base plate, and moving wheels, the base plate drives the moving wheels for lifting and adjusting. When the equipment needs to be moved, the moving wheels are brought into contact with the ground for easy movement; when stationary, the moving wheels are retracted and stabilized by support columns. The worm gear transmission has a large transmission ratio and smooth operation, preventing the worktable from shaking or jamming during rotation. It can precisely adjust the worktable to the required angle, ensuring the accuracy of crane operation. The flexible switching between working and moving states allows the crane to quickly adapt to different operating scenarios, improving equipment efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 An adjustable base for a crane includes: a base 1, a controller 2 on one side of the base 1, four sets of support columns 5 fixedly installed at the bottom of the base 1, a rotating shaft 11 and a worm gear 13 rotatably installed inside the base 1, a worm wheel 12 fixedly installed on the outside of the rotating shaft 11, a worktable 4 fixedly installed on the top of the rotating shaft 11, a rotating ring 10 fixedly installed at the bottom of the worktable 4, a rotating seat 9 fixedly installed on the top of the base 1, a support plate 14 fixedly installed at the bottom of the base 1, a hydraulic cylinder 15 fixedly installed on one side of the support plate 14, two sets of inclined blocks 16 slidably installed at the bottom of the base 1, a connecting block 17 fixedly installed between the two sets of inclined blocks, four sets of lifting rods 20 fixedly installed at the bottom of the two sets of lifting rods 20, a base plate 7 fixedly installed at the bottom of the base plate 7, four sets of moving wheels 8 provided at the bottom of the base plate 7, and two sets of inclined blocks 18 fixedly installed on the top of the base plate 7.

[0021] In this embodiment, four sets of fastening bolts 6 are movably inserted into the bottom of each of the four sets of support columns 5. The rotating ring 10 is rotatably installed in the rotating seat 9. One side of one set of inclined blocks 16 is fixedly installed on the output end of the hydraulic cylinder 15, and the two sets of inclined blocks 16 are slidably installed on one side of the corresponding inclined blocks 18.

[0022] In this embodiment, a drive motor 3 is fixedly installed on one side of the base 1, and one end of the worm gear 13 is fixedly installed on the output end of the drive motor 3.

[0023] In this embodiment, the worm gear 12 meshes with the worm 13, and the worm gear 12 is disposed inside the base 1.

[0024] In this embodiment, a sliding groove is provided at the bottom of the base 1, and two sets of inclined blocks 16 are slidably installed in the sliding groove.

[0025] In this embodiment, the inclined surfaces of the two sets of inclined blocks 18 are provided with inclined grooves 19, and the two sets of inclined blocks 16 are slidably installed in the corresponding inclined grooves 19.

[0026] In this embodiment, during use, the hydraulic cylinder 15 on one side of the support plate 14 is activated by the start controller 2. The output end of the hydraulic cylinder 15 pushes one of the inclined blocks 16 fixedly connected to it. Since the two inclined blocks 16 are fixedly connected by the connecting block 17 and slidably installed in the groove opened at the bottom of the base 1, the two inclined blocks 16 will slide in the groove under the action of the hydraulic cylinder 15. At the same time, the inclined blocks 16 are also slidably installed in the inclined groove 19 opened on the inclined surface of the inclined block 18. As the inclined blocks 16 slide, they will push the inclined block 18 to move in the inclined groove 19. The inclined block 18 is fixedly installed on the base plate 7. The base plate 7 is connected to the base 1 through four sets of lifting rods 20. Therefore, the movement of the inclined block 18 will drive the base plate 7 and the moving wheels 8 to move up and down along the lifting rods 20. When the moving wheels 8 touch the ground, it is convenient to move the equipment. When the support legs touch the ground, they are used with the fastening bolts 6 to fix the base 1 to the ground to ensure stability.

[0027] When the angle of the worktable 4 needs to be adjusted, the controller 2 starts the drive motor 3 on one side of the base 1. The output end of the drive motor 3 drives the worm gear 13 to rotate. Since the worm wheel 12 meshes with the worm gear 13 and the worm wheel 12 is fixedly installed on the outside of the rotating shaft 11, the worktable 4 is fixedly installed on the top of the rotating shaft 11, and the rotating ring 10 at the bottom of the worktable 4 is rotatably installed in the rotating seat 9 on the top of the base 1. Therefore, the rotation of the worm gear 13 will drive the worm wheel 12 to rotate, thereby causing the rotating shaft 11 to drive the worktable 4 to rotate under the restriction of the rotating ring 10 and the rotating seat 9, so as to realize the adjustment of the angle of the worktable 4, which makes it convenient for the crane to operate in different directions.
