Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to a pile foundation construction auxiliary platform for foundation engineering. Background Art

[0002] The pile foundation is a deep foundation composed of a pile and a pile-steel staggered composite cap connected to the top of the pile, or a single pile foundation connected by a column and the pile foundation. If the pile body is completely buried in the soil and the bottom surface of the steel staggered composite cap is in contact with the soil, it is called a low steel staggered composite cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the steel staggered composite cap is above the ground, it is called a high steel staggered composite cap pile foundation; when carrying out pile foundation construction on the foundation, a pile foundation construction auxiliary platform is required.

[0003] Please refer to the pile foundation construction auxiliary platform for foundation engineering with announcement number CN216515700U. In this patent, it is proposed that "the existing auxiliary platform can only fix pile foundations of the same specification when in use, and cannot fix pile foundations of different specifications according to actual conditions, which is difficult to meet the use requirements, and the stability is poor, and the pile foundation is prone to tilt, which reduces the practicality of the device." The above embodiment can push the fixed plate to move toward the pile foundation by rotating the screw rod, and then the pile foundation can be clamped and fixed from three sides at the same time through three fixed plates, and the fixing effect of the pile foundation is strengthened by the elasticity of the spring, which is convenient for fixing pile foundations of different specifications;

[0004] However, the fixing mechanisms in the three directions in the above-mentioned embodiment are all arranged on independent support plates. When in use, the fixing mechanisms in different directions need to be adjusted separately, which is not only troublesome to operate and reduces work efficiency, but also affects the positioning accuracy (concentricity) of the pile foundation and the auxiliary platform. If there is a deviation in the positioning, it will affect the force on the pile foundation in different directions, so that the verticality of the pile foundation is affected, and the fixing effect of the pile foundation is reduced. In view of this, the present application proposes a pile foundation construction auxiliary platform for foundation engineering. Utility Model Content

It solves the problem that the existing auxiliary platform can only fix pile foundations of the same specification when in use, and cannot fix pile foundations of different specifications according to actual conditions, which is difficult to meet the use requirements and has poor stability, affecting the supporting effect on the pile foundation, causing the pile foundation to easily tilt, and reducing the practicability of the device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pile foundation construction auxiliary platform for foundation engineering, comprising a base, the top of which is fixedly connected with a tightening positioning mechanism;

[0010] Furthermore, the outer side of the fixed cylinder is fixedly connected with an upper limit seat and a lower limit seat located on the upper and lower sides of the rotating ring, and the threaded rod is slidably adapted to the lower limit seat, and the upper limit seat and the lower limit seat are both annular.

[0011] Furthermore, a movable opening is provided inside the base, and a plurality of support bases are fixedly connected to the bottom of the base.

[0012] Furthermore, the outer side of the rotating sleeve and the inner side of the rotating ring are both fixedly connected with limiting rings that are slidably adapted to the fixed tube, and the outer side of the rotating ring is fixedly connected with a plurality of handles.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The pile foundation construction auxiliary platform for foundation engineering, through the set fastening positioning mechanism, can control the rotation of the rotating ring by holding the handle, so that the rotating ring utilizes the transmission effect of the transmission gear ring and the transmission gear to drive the rotating sleeves in different directions to rotate synchronously, thereby facilitating the use of the connection effect of the rotating sleeve and the threaded rod, and synchronously adjusting the abutment plates in three directions. While simplifying the operation steps, it is convenient to fix pile foundations of different specifications.

[0025] In this embodiment, the outer side of the fixed cylinder 2 is rotatably connected to a rotating ring 6, and the outer side of the rotating sleeve 3 and the inner side of the rotating ring 6 are fixedly connected to a limiting ring that is slidably adapted to the fixed cylinder 2, so that the rotating ring 6 and the rotating sleeve 3 can be rotated at a fixed position in the fixed cylinder 2 by using the limiting ring. The outer side of the rotating ring 6 is fixedly connected to a plurality of handles 11, so that the user can hold the handles 11 to control the rotation of the rotating ring 6.
