Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a lifting equipment for transporting pipe piles in the pipe pile industry. Background Technology

[0002] With the development of my country's construction industry, building materials are the foundation of construction projects. Various building materials are needed in construction projects, generally categorized into structural materials, decorative materials, and special-purpose materials. Cement pipe piles are a commonly used building material, primarily used in the foundation construction of railway bridges. They are made by placing steel bars and concrete into molds, allowing for splicing to any length, unrestricted by construction conditions. The piles exhibit good resistance to hammering and cracking, ensuring reliable quality. Pipe piles require lifting and transportation using pipe pile lifting equipment during manufacturing, construction, and transportation.

[0003] Existing pipe pile lifting tools are difficult to use because it is hard to adjust the spacing of the clamps on both sides at the bottom. This makes it difficult to clamp and fix shorter pipe piles, requiring the use of pipe pile lifting tools of other sizes. When clamping and transporting longer pipe piles, the clamps on both sides clamp the center of the pipe pile, resulting in uneven force on the entire pipe pile. This causes instability in the clamping, making the pipe pile prone to shaking or even falling during transportation, resulting in unsatisfactory performance.

[0004] Therefore, this utility model provides a pipe pile conveying lifting tool for the pipe pile industry to solve the above problems. Utility Model Content

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.

[0027] This utility model provides a pipe pile conveying hoist for the pipe pile industry, including a movable frame 1. Columns 2 are provided on both sides of the inner wall of the movable frame 1. Connectors are slidably connected to the outer surface of the columns 2. A lifting plate 3 is fixedly installed on the surface of the connector. A clamping assembly 4 is provided on the surface of the lifting plate 3. Universal wheels are provided at the four corners of the lower surface of the movable frame 1. The clamping assembly 4 includes a first sliding groove formed on the surface of the lifting plate 3. A sliding block 401 is slidably connected inside the first sliding groove. Support plates 402 are fixedly installed on both sides of the lower surface of the sliding block 401. 2 has a rotating column internally connected to it. A driven gear 404 is fixedly installed on the outer surface of the rotating column. Two driven gears 404 are meshed on one side with a double-sided toothed plate 405. A second sliding groove is formed on the surface of the sliding block 401. The double-sided toothed plate 405 is slidably connected inside the second sliding groove. A connecting rod 406 is fixedly installed on the upper surface of the double-sided toothed plate 405. A lifting column 407 is connected inside the connecting rod 406. A driven plate 408 is fixedly installed on the outer surface of the rotating column. A groove is formed on the surface of the driven plate 408. One end of the driven plate 408 is fixedly installed with... The fixture plate 409 has a guide post fixedly installed on the inner wall of the first slide groove. A sliding block 401 is slidably connected to the outer surface of the guide post. Anti-slip strips 410 are provided on the inner wall of the fixture plate 409. There are several anti-slip strips 410. Stabilizers are fixedly installed at both ends of the rotating column. The stabilizers are fixedly installed on the side surface of the fixture plate 409. An electric push rod 411 is fixedly installed on the upper surface of the moving frame 1. A connecting ring is fixedly installed at one end of the electric push rod 411. A lifting column 407 is fixedly installed inside the connecting ring. Both ends of the lifting column 407 are fixed. A telescopic plate is installed and fixedly mounted on the upper surface of the lifting plate 3. A guide is slidably connected to the outer surface of the connecting rod 406 and fixedly mounted on the upper surface of the sliding block 401. A double-acting screw 412 is threadedly connected to the inner surface of the two sliding blocks 401. A retaining pin is fixedly mounted at one end of the double-acting screw 412. A drive motor 403 is fixedly mounted on the side surface of the lifting plate 3 through the frame. A drive shaft is fixedly mounted at the output end of the drive motor 403. Pulleys are fixedly mounted on the outer surfaces of the drive shaft and the retaining pin, and belts are overlapped on the outer surfaces of the pulleys.

[0028] The lifting plate 3 is moved above the pipe pile, and then the drive motor 403 is started to drive the drive shaft to rotate. The drive shaft drives the clamping shaft and the double-acting screw 412 on the other side to rotate through the pulley. The rotation of the double-acting screw 412 causes the sliding blocks 401 on both sides to slide inside the first sliding groove. The sliding blocks 401 drive the clamping plate 409 below to slide to both ends of the pipe pile. The sliding blocks 401 drive the internal connecting rod 406 to slide. The connecting rod 406 slides on the outer surface of the lifting column 407. After the clamping plate 409 slides to both ends of the pipe pile, the electric push rod 411 is started to drive the internal lifting column 407 to slide upward through the connecting ring. The lifting column 407 moves stably under the guidance of the telescopic plates on both sides. The lifting column 407 drives the connecting rod 406 on the outer surface to move. The connecting rod 406 slides upward inside the sliding block 401, causing the double-sided toothed plate 405 at the bottom to slide upward. The movement of the double-sided toothed plate 405 causes the driven gear 404 to rotate, which in turn causes the internal rotating column to rotate. The rotating column rotates inside the support plate 402, which in turn causes the driven plate 408 on the outer surface and the stabilizing members on both sides to move synchronously. This causes the clamping plate 409, which is fixedly connected at one end, to rotate, thereby clamping the pipe pile below. The clamping plate 409 clamps the pipe pile at both ends, making the force on the pipe pile more uniform during movement, thus improving the stability of clamping and greatly avoiding the pipe pile shaking or even falling during transportation, thus improving the stability of the device during transportation.

[0029] An electric winch 5 is installed on the surface of the mobile frame 1, and the steel wire rope inside the electric winch 5 is fixedly connected to the upper surface of the lifting plate 3.

[0030] By activating the electric winch 5, the internal steel wire rope is driven to move. The steel wire rope causes the lifting plate 3 and the connecting parts to slide on the outer surface of the column 2, so that the lifting plate 3 can be lifted and lowered stably, which facilitates the clamping operation of the pipe pile in the early stage and the subsequent transportation operation.

[0031] A hoisting frame 6 is fixedly installed on the upper surface of the mobile frame 1, and hoisting lugs 7 are fixedly installed on both sides of the upper surface of the hoisting frame 6.

[0032] An external crane can be connected to the lifting lug 7, allowing for the overall transportation of the device and the internal pipe piles.
