Description

Technical Field

[0001] This utility model relates to the field of pile lifting technology, specifically a lifting device for stacked square piles. Background Technology

[0002] Precast piles, as a technologically mature pile type, are widely used in various engineering construction fields due to their advantages such as easy assurance of pile quality, ability to withstand large loads, and robust durability. Precast piles can be manufactured in factories or on-site, depending on usage requirements and construction plans. During the fabrication of precast piles, it is usually necessary to lift and move the completed piles.

[0003] In existing technologies, when transferring piles, the piles after driving are stacked and then lifted together. Because the stacked piles are heavy, it is inconvenient to directly use slings to secure them during lifting. Furthermore, the stacked piles are prone to tipping over and falling during lifting, resulting in damage. To address these issues, an innovative design is implemented based on the existing lifting device. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting device for stacked square piles to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for stacked square piles, comprising a lifting base plate, lifting rings fixed at both ends of the upper surface of the lifting base plate, and an installation sleeve fixed inside the lifting rings on the upper surface of the lifting base plate. A column is provided inside the installation sleeve, and multiple support brackets are installed on the surface of the column. A first crossbar and a second crossbar are respectively installed in the support brackets. The surfaces of the first crossbar and the second crossbar are each provided with a mounting slot, and a pin is provided in the mounting slot. The pin is connected to the support bracket.

[0006] Preferably, the lower end of the column is inserted into the mounting sleeve, and a bolt is installed on the mounting sleeve. One end of the bolt extends into the mounting sleeve and is pressed against the surface of the column.

[0007] Preferably, the support frame has an "L" shaped structure, and the support frames are staggered on the surface of the column.

[0008] Preferably, the surface of the pin is provided with a support rod, and the inside of the support frame is provided with a guide groove, with the support rod located in the guide groove.

[0009] Preferably, a return spring is fixedly installed on the surface of the support rod, and the end of the return spring away from the support rod is fixed to the inner wall of the guide groove.

[0010] Preferably, the pin and the support frame are connected through.

[0011] Preferably, a plurality of the support brackets are evenly spaced on the surface of the column.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this stacked square pile lifting device, the piles are stacked on the lifting base plate, and the piles on the lifting base plate are lifted in a concentrated manner by hooking them onto the lifting ring. After the piles are stacked, the column is inserted into the installation sleeve and tightened with bolts. Then, the first and second horizontal bars are placed in the support frame, and the return spring pushes the support rod to slide in the guide groove, thereby the support rod drives the pin to insert into the mounting slot on the surface of the first and second horizontal bars. At this time, the first and second horizontal bars are locked, and the first horizontal bar, the second horizontal bar and the column form a fence to protect the outside of the stacked piles, improving the lifting stability.

[0018] 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.

[0019] Please see Figures 1-4This utility model provides a lifting device for stacked square piles, including a lifting base plate 1. Lifting rings 2 are fixed at both ends of the upper surface of the lifting base plate 1. An installation sleeve 3 is also fixed inside the lifting rings 2 on the upper surface of the lifting base plate 1. A column 4 is provided inside the installation sleeve 3. Multiple support brackets 6 are installed on the surface of the column 4. A first crossbar 7 and a second crossbar 8 are respectively installed in the support brackets 6. The surfaces of the first crossbar 7 and the second crossbar 8 are provided with mounting slots 9. A pin 10 is provided in the mounting slot 9 and is connected to the support bracket 6.

[0020] In one or more embodiments of this utility model, the lower end of the column 4 is inserted into the mounting sleeve 3, and a bolt 5 is installed through the mounting sleeve 3. One end of the bolt 5 extends into the mounting sleeve 3 and presses against the surface of the column 4, so that the column 4 can be stably installed in the mounting sleeve 3.

[0021] In one or more embodiments of this utility model, the support frame 6 has an "L" shaped structure, and the support frame 6 is staggered on the surface of the column 4, which is conducive to the installation of the first crossbar 7 and the second crossbar 8 within the support frame 6.

[0022] In one or more embodiments of this utility model, a support rod 11 is provided on the surface of the pin 10, and a guide groove 12 is provided inside the support frame 6. The support rod 11 is located in the guide groove 12. The support rod 11 and the guide groove 12 cooperate to guide the movement direction of the pin 10 and prevent the pin 10 from disengaging from the support frame 6.

[0023] In one or more embodiments of this utility model, a return spring 13 is fixedly installed on the surface of the support rod 11. The end of the return spring 13 away from the support rod 11 is fixed to the inner wall of the guide groove 12, so that the return spring 13 can push the support rod 11 to slide in the guide groove 12, thereby facilitating the support rod 11 to drive the pin 10 to move synchronously.

[0024] In one or more embodiments of this utility model, the pin 10 and the support frame 6 are connected through, which facilitates the pin 10 to move back and forth on the support frame 6.

[0025] In one or more embodiments of this utility model, a plurality of the support brackets 6 are evenly spaced on the surface of the column 4, which ensures that there is sufficient gap between adjacent layers and that the force on the entire device is more balanced.

[0026] according to Figures 1-4As shown, firstly, the precast square piles are stacked on the lifting base plate 1. Then, the column 4 is inserted into the installation sleeve 3, and then the bolts 5 on the installation sleeve 3 are tightened until the bolts 5 are firmly against the column 4. After the column 4 is installed, the two ends of the first horizontal bar 7 and the second horizontal bar 8 are respectively placed into the support brackets 6 on the surface of different columns 4. During the erection process, the pins 10 are manually pulled outwards from the support brackets 6. After the first horizontal bar 7 and the second horizontal bar 8 are placed into the support brackets 6, the pins 10 are released. When the moving pin 10 is engaged, the return spring 13 pushes the support rod 11 to move within the guide groove 12. The support rod 11 then drives the pin 10 to move synchronously until the pin 10 is inserted into the mounting slot 9 on the surface of the first crossbar 7 and the second crossbar 8. The first crossbar 7 and the second crossbar 8 are then locked. At this time, the first crossbar 7, the second crossbar 8, and the column 4 form a protective enclosure on the outside of the square pile. The crane hook can then be hung in the lifting ring 2 to lift the square piles stacked on the lifting base plate 1.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
