[0002] Pipe column steel molds are specialized steel molds used to produce pipe column structures. Their structure is mostly segmented or two-part, with tongue and groove and flange components to ensure sealing and concentricity. They are made of high-strength steel through precision welding and machining processes, and have the characteristics of high tensile strength, wear resistance and no deformation, and high forming accuracy. They can ensure accurate pipe column dimensions and smooth surfaces. Technological development is driven by the higher requirements of engineering for pipe column quality and production efficiency, and the process and structure are continuously optimized to solve problems such as grout leakage and compatibility.

A sliding rod 1 is slidably connected to a sliding rod 2 on its inner wall. A second piston bracket is fixedly connected to the outer wall of the sliding rod 2. Springs are fixedly connected to the inner walls of both the hollow outer shell 1 and the second piston bracket. A first fixing pin is slidably connected to the inner wall of the spring. Hollow outer shell 2 is slidably connected to the outer wall of the first fixing pin. Multiple locking holes are provided on the inner walls of both the first auxiliary beam and the second auxiliary beam. A second fixing pin is slidably connected to the inner wall of the hollow outer shell 2. A lifting mechanism is slidably connected to the outer wall of the main beam. The lifting mechanism is used to lift objects.

A rotating block is rotatably connected inside the rope shell. A steel rope is wound around the outer wall of the rotating block. An extension rope is fixedly connected to the bottom end of the steel rope. A third fixing block is fixedly connected to the bottom end of the extension rope. A first fixing block is rotatably connected to the inner wall of the third fixing block. A second fixing hook is rotatably connected to the bottom of the first fixing block. A first fixing hook lock is fixedly connected to the bottom of the middle slider.
[0008] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:
[0013] A limiter is fixedly connected to the bottom center of the main beam, and a third buffer pad is fixedly connected to the bottom of the limiter.
[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, during the hoisting of the tubular steel membrane, the electric control piston bracket pushes the hydraulic telescopic rod to drive the first and second auxiliary beams to extend and retract from the inside out according to the length of the tubular steel membrane. When the auxiliary beam extends and retracts to the limit distance, the spring will automatically spring the pin into the slot of the auxiliary beam to prevent the auxiliary beam from derailing. This helps to better hoist tubular steel membranes of different lengths, and the pin can greatly avoid the occurrence of safety accidents, improve the efficiency of use, and expand the scope of application.
[0022] 2. In this utility model, when the length of the steel membrane of the tubular column is appropriate, the lifting device will automatically descend to the appropriate position and use the first fixing hook to load the steel membrane. The lifting roller is used to fix the steel membrane. When encountering a steel membrane that is too long, the auxiliary beam is extended and the left and right sides of the steel membrane are fixed for a second time using the second fixing hook to prevent insufficient lifting force of the first fixing hook. This effectively solves the problem of swaying of the tubular steel membrane during the lifting process and greatly ensures that the steel membrane will not deform due to operation.

[0031] 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.
[0032] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 6 This utility model provides an embodiment of a hoisting and deformation-resistant lifting device for steel formwork of pipe piles, comprising a main beam 1, a first auxiliary beam 3 slidably connected to the left side of the inner wall of the main beam 1, multiple hollow shells 12 fixedly connected to the front edge of the main beam 1, a second auxiliary beam 4 slidably connected to the inner wall of the first auxiliary beam 3, a hollow shell 21 fixedly connected to the front side of the second auxiliary beam 4, a first piston bracket 7 fixedly connected to the top of the main beam 1, a hydraulic telescopic rod 8 slidably connected to the right side of the first piston bracket 7, and sliding rods 9 slidably connected to the left and right sides of the inner wall of the hydraulic telescopic rod 8. The inner wall of the 9 is slidably connected to the sliding rod 10. The outer wall of the sliding rod 10 is fixedly connected to the second piston bracket 22. The inner walls of the hollow outer shell 12 and the second piston bracket 22 are both fixedly connected to the spring 15. The inner wall of the spring 15 is slidably connected to the first fixing pin 16. The outer wall of the first fixing pin 16 is slidably connected to the hollow outer shell 17. The inner walls of the first auxiliary beam 3 and the second auxiliary beam 4 are both provided with multiple locking holes 24. The inner wall of the hollow outer shell 17 is slidably connected to the second fixing pin 18. The outer wall of the main beam 1 is slidably connected to the lifting mechanism 2, which is used to lift objects.
[0033] Specifically, the structure is based on the main beam 1, and multi-stage telescopic movement is achieved through the nested sliding of the main beam 1 and the first auxiliary beam 3, and the first auxiliary beam 3 and the second auxiliary beam 4. The first piston bracket 7 at the top of the main beam 1 is connected to the hydraulic telescopic rod 8, which transmits power through the sliding rod 1 9, the sliding rod 2 10 and the second piston bracket 22. The hollow shell 1 12 on the main beam 1 and the spring 15 in the second piston bracket 22 cooperate with the first fixing pin 16, the hollow shell 2 17 and the second fixing pin 18 to engage and fix with the locking holes 24 on the first auxiliary beam 3 and the second auxiliary beam 4. The hollow shell 3 21 of the second auxiliary beam 4 works in coordination. The lifting mechanism 2 on the outer wall of the main beam 1 can be used to flexibly lift objects.
[0034] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 5 The lifting mechanism 2 includes a slider 202, a fixed block 209 fixedly connected to the slider 202, a rope shell 210 fixedly connected to the bottom of the fixed block 209, a rotating block 212 rotatably connected inside the rope shell (210), a steel rope 211 wound around the outer wall of the rotating block 212, an extension rope 213 fixedly connected to the bottom end of the steel rope 211, a fixed block 3 203 fixedly connected to the bottom end of the extension rope 213, a fixed block 1 208 rotatably connected to the inner wall of the fixed block 3 203, a second fixed hook 206 rotatably connected to the bottom of the fixed block 1 208, and a first fixed hook lock 201 fixedly connected to the bottom of the middle slider 202.
[0035] Specifically, the lifting mechanism 2 is based on the slider 202. The slider 202 is fixedly connected to the second fixing block 209 for supporting the rope system on one side, and the bottom of the middle part is also fixedly connected to the first fixing hook lock 201 to assist in the lifting and fixing. The rope shell 210 at the bottom of the second fixing block 209 provides protection and support for the internal components. The rotating block 212 connected inside can rotate flexibly. By rotating, the steel rope 211 wrapped around the outer wall can be wound and unwound. The extension rope 213 connected to the bottom end of the steel rope 211 can extend the lifting distance. The inner wall of the third fixing block 203 at the bottom end of the extension rope 213 is rotatably connected to the first fixing block 208. The second fixing hook 206 rotatably connected to the bottom of the first fixing block 208 can be flexibly adjusted to adapt to the hooking requirements of different objects. The whole system constitutes a complete and flexible lifting system.
[0036] Please see the appendix Figure 1 , attached Figure 2 and attached Figure 6The limiting device 207 is fixedly connected to the opposite side of the multiple second auxiliary beams 4. The inner wall of the card hole 24 is slidably connected to the outer wall of the first fixed pin 16. The bottom middle of the main beam 1 is fixedly connected to the limiter 19. The bottom of the limiter 19 is fixedly connected to the third buffer pad 20. The outer wall of the first fixed hook lock 201 is fixedly connected to the second buffer pad 14. The outer wall of the second fixed hook 206 is fixedly connected to the first buffer pad 13.
[0037] Specifically, each of the two secondary auxiliary beams 4 is fixedly connected to a limiting device 207 on the side away from each other. These limiting devices 207 can effectively prevent the secondary auxiliary beams 4 from slipping out of the connection due to excessive sliding during the extension and retraction process, and play a precise limiting protection role. The inner wall of the locking hole 24 is slidably connected to the outer wall of the first fixing pin 16. This cooperation method allows the first fixing pin 16 to be smoothly inserted into or pulled out of the locking hole 24, ensuring stable fixation in different extension and retraction positions. The limiter 19 fixedly connected to the bottom center of the main beam 1 can limit the range of motion of the lower components. The third buffer pad 20 fixedly connected to its bottom can reduce the impact force of collision when in contact. The second buffer pad 14 fixedly connected to the outer wall of the first fixing hook lock 201 can play a buffer protection role when hooking or contacting other objects to avoid wear. The first buffer pad 13 fixedly connected to the outer wall of the second fixing hook 206 reduces the wear on the object and the hook itself when hooking objects, improving the safety and durability of use.
[0038] Please see the appendix Figure 1 and attached Figure 4 The top of the main beam 1 is fixedly connected to the operation panel 11, the top of the main beam 1 is fixedly connected to the backup power supply 6, the middle of the outer wall of the main beam 1 is slidably connected to the hoisting roller 204, the outer wall of the hoisting roller 204 is fixedly connected to the level 205, the top of the main beam 1 is fixedly connected to the nameplate 5, and the inner wall of the nameplate 5 is threaded with multiple screws 23.
[0039] Specifically, the top of the main beam 1 is not only fixedly connected to an operation panel 11 for easy control of the entire lifting device by the operator, but also equipped with a backup power supply 6 for emergency power supply in case of main power failure. As a lifting device for anti-deformation of pipe pile steel formwork, the lifting roller 204 slidably connected in the middle of the outer wall of the main beam 1 can assist in adjusting the lifting position. The level 205 fixedly connected to the outer wall of the roller can monitor whether the lifting device is in a horizontal state in real time to ensure stable lifting. In addition, the top of the main beam 1 is also fixedly connected to a nameplate 5 that marks the specifications, parameters and other information of the lifting device. The nameplate 5 is firmly fixed to the main beam 1 by multiple screws 23 connected by the inner wall thread to ensure that the information is clear and lasting.
[0040] Working principle: During the hoisting of the steel membrane column, the electric control of the first piston bracket 7 pushes the hydraulic telescopic rod 8 and the sliding rod 1 9 to drive the first auxiliary beam 3 to extend outward along the inside of the main beam 1 through the second piston bracket 22. When the length of the steel membrane column is too long, the sliding rod 2 10 drives the second auxiliary beam 4 to extend outward along the inside of the first auxiliary beam 3. The first fixed pin 16 will automatically lock inward by the force of the spring 15 when the second auxiliary beam 4 extends outward to a certain length to prevent the second auxiliary beam 4 from derailing.
[0041] During the hoisting and installation of the steel membrane column, when the length of the steel membrane column is appropriate, the lifting device will descend. When the limit switch 19 touches the steel membrane column, the lifting device will stop descending. The first fixing hook lock 201 is used to load the steel pipe and the lifting roller 204 is used to fix the steel membrane column to prevent the steel membrane column from shaking. When the length of the steel membrane column is too long, the first auxiliary beam 3 and the second auxiliary beam 4 are electrically operated to extend the length to a suitable distance for the steel membrane column. The second fixing hook 206 is used to fix both sides of the steel membrane column column to prevent the first fixing hook lock 201 from being insufficient in lifting force, which would cause the steel membrane column to deform.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
