Technical Field

[0001] The present application relates to the technical field of pile frames, and in particular to a crawler type hydraulic pile frame platform. Background Art

[0002] The pile frame is an important part of pile construction machinery. It is used to hang the pile hammer, lift the pile and put the pile in place, and guide the pile hammer and pile cap when driving the pile. It is also used to install various hole-making devices, guide the hole-making devices, and provide power to complete the hole-making work. Modern pile frames can generally be equipped with a variety of working devices for pile foundation construction, which require functions such as rotation, amplitude change and travel.

[0003] The existing patent (publication number: CN 217974369 U) discloses a pile frame platform that is easy to transfer and transport, including: a first splicing plate, a second splicing plate and a third splicing plate are respectively arranged on both sides of the first splicing plate, and the outer sides of the second splicing plate and the third splicing plate are fixedly installed with plug-in columns 1 and 2. When in use, the crane is turned on, and the first splicing plate, the second splicing plate or the third splicing plate can be lifted by using the fixing plate 1, the connecting column and the fixing seat 2, and the first splicing plate, the second splicing plate or the third splicing plate can be assembled together. The first splicing plate, the second splicing plate and the third splicing plate can be quickly plugged in with the plug-in slot 2 using the plug-in column 2. At the same time, the first splicing plate and the first splicing plate can also be quickly plugged in and assembled with the connecting rod and the plug-in slot 1. The first splicing plate, the second splicing plate and the third splicing plate can be positioned, fastened and installed by using the threaded hole 1, the plug-in slot 2, the threaded hole 2 and the plug-in slot 1. The design is reasonable and the assembly is convenient.

[0004] The above-mentioned pile frame platform needs to be frequently spliced ​​during assembly or disassembly, and after the splicing is completed, it needs to be fixed in sequence with bolts, which is laborious, increases the workload of workers, and reduces work efficiency. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a crawler hydraulic pile frame platform, which has the advantages of being able to directly retract and deploy the pile frame platform, without requiring excessive manpower, reducing the workload of workers, and improving work efficiency. It solves the problem that the existing pile frame platform requires frequent splicing during assembly or disassembly, and after the splicing is completed, it needs to be fixed in sequence with bolts, which is more laborious, increases the workload of workers, and reduces work efficiency.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a crawler hydraulic pile frame platform, comprising a crawler walking chassis, the upper surface of the crawler walking chassis is fixedly connected to a base, the internal sliding connection of the base is connected to two retractable platforms, the right side of the base is fixedly connected to a motor, the internal rotation of the motor is connected to an output shaft, the outer circumferential surface of the output shaft is connected to the internal rotation of the base, the outer circumferential surface of the output shaft is threadedly connected to two threaded tubes, the outer circumferential surface of each threaded tube is fixedly connected to a connecting plate, the other end of the connecting plate is respectively fixedly connected to the front of the retractable platform, and the upper surface of the base is fixedly connected to a top plate.

[0007] Through the above scheme, since the existing pile frame platform needs to be frequently spliced ​​during assembly or disassembly, and after the splicing is completed, it needs to be fixed in sequence with bolts, which is more laborious, increases the workload of workers, and reduces work efficiency. The output shaft drives the threaded pipe to move in the relative direction during the rotation process, prompting the connecting plate to drive the retracting and releasing platform to move and retract, and the pile frame platform can be directly retracted and used without excessive manpower consumption, reducing the workload of workers and improving work efficiency.

[0008] Furthermore, the outer circumferential surface of the output shaft is provided with two sections of thread structures, and the thread track directions of the two sections of thread structures on the outer circumferential surface of the output shaft are opposite.

[0009] Through the above scheme, the threaded tube is forced to move in the relative direction, thereby causing the retractable platform to move in the relative direction for retraction and extension.

[0010] Furthermore, a limiting groove is provided inside the base, and the outer surface of the connecting plate is slidably connected to the base via the limiting groove.

[0011] Through the above solution, the threaded tube is restricted to prevent the threaded tube from rotating with the output shaft, so that the threaded tube is always moved laterally.

[0012] Furthermore, each of the retractable and unfolding platforms is fixedly connected to two hydraulic cylinders, the bottom end of each hydraulic cylinder is fixedly connected to a universal ball, and the bottom end of the universal ball is fixedly connected to a bottom plate.

[0013] Through the above solution, the hydraulic cylinder drives the bottom plate to move downward, thereby supporting the entire pile frame platform. The universal ball can make the bottom plate fit the ground, increasing the stability of the entire pile frame platform.

[0014] Furthermore, a slider is fixedly connected to the back of each of the retractable platforms, a slide groove is provided inside the base, and the outer surface of the slider is slidably connected to the base via the slide groove.

[0015] Through the above scheme, the retractable platform is restricted, so that the retractable platform is always moved laterally, and the stability of the retractable platform movement is further increased.

[0016] Furthermore, two positioning seats are fixedly connected to the back of the base, a control rod is rotatably inserted inside each of the positioning seats, the outer circumferential surface of the control rod is threadedly connected to the positioning rod, and a positioning hole is opened inside the slider.

[0017] Through the above scheme, the control rod can drive the positioning rod to move during rotation, so that the positioning rod can be inserted into the positioning hole after the retractable platform is fully opened, thereby reinforcing the retractable platform, preventing the retractable platform from moving back easily, and increasing the stability of the retractable platform.

[0018] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the positioning seat.

[0019] Through the above solution, the control rod is restricted to prevent the control rod from sliding and deviating, thereby increasing the stability of the control rod movement.

[0020] Furthermore, two limiting blocks are fixedly connected to the outer circumferential surface of the positioning rod, and the outer surface of each limiting block is slidably connected to the positioning seat through a hollow groove provided inside the positioning seat.

[0021] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating along with the control rod, so that the positioning rod is always moved laterally.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The crawler type hydraulic pile frame platform drives the threaded pipe to move in the relative direction during the rotation of the output shaft, prompting the connecting plate to drive the retracting and extending platform to move and retract, so that the pile frame platform can be directly retracted and extended without excessive manpower consumption, reducing the workload of workers and improving work efficiency. This solves the problem that the existing pile frame platform is more laborious during assembly or disassembly, which increases the workload of workers and reduces work efficiency.

The universal ball 11 can cause the bottom plate 10 to fit the ground, thereby increasing the stability of the entire pile frame platform.

[0036] See also Figure 2 and Figure 4 A slider 13 is fixedly connected to the back of each folding and unfolding platform 3, and a slide groove 14 is provided inside the base 2. The outer surface of the slider 13 is slidably connected to the base 2 through the slide groove 14, which restricts the folding and unfolding platform 3, prompting the folding and unfolding platform 3 to always move horizontally, further increasing the stability of the movement of the folding and unfolding platform 3.
