Technical Field

[0001] The invention relates to the technical field of building foundation construction, in particular to a device for measuring the verticality of a square pile body. Background Art

[0002] The verticality of the pile body needs to be strictly controlled during the construction of the pile foundation project. In traditional construction, the theodolite is used to monitor the verticality of the pile body, but the theodolite is easily affected by wind and vibration during the pile hammer driving process, which affects the observation and control of the verticality of the pile body and causes quality problems. In serious cases, the pile body will break. If it is measured by a simple tape measure, it will take a lot of time and manpower. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the existing pile verticality measuring device has low efficiency and the theodolite is greatly affected by the environment.

[0004] In order to solve the above problem, the present invention provides a verticality measuring device which can improve the measuring efficiency and is not affected by the environment. The specific scheme is: A device for measuring the verticality of a square pile body comprises an F-shaped measuring card and a rotating device fixed on the top of a pile driver, the rotating device being located above the square pile, at least two vertical lines being wound around the rotating device, plumb bobs being fixed at the lower ends of the vertical lines, the two vertical lines respectively extending downward along two adjacent surfaces of the square pile, upper and lower corresponding scale lines being arranged on the two horizontal sides of the F-shaped measuring card, and the front end of the F-shaped measuring card being used for abutting against the square pile.

[0005] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: By using the measuring device of the present invention, the vertical line is unfolded by the rotating device when in use, so that two plumb bobs are lowered to positions close to two adjacent surfaces of the square pile. The measurement is to place the F-shaped measuring card against the surface to be measured of the square pile, and observe whether the scales of the two horizontal sides of the F-shaped measuring card are the same when the vertical line droops naturally. If they are the same, it means that the square pile is vertical, and if they are different, it means that the square pile is not vertical, and adjustments are made until the square pile is vertical. After the measurement is completed, the vertical line can be wound by the rotating device without affecting the normal piling operation.

[0006] Preferably, a further technical solution of the present invention is: The rotating device includes a driving motor and a roller shaft, the rotating shaft of the driving motor is coaxially fixed with the roller shaft, and the driving motor drives the roller shaft to rotate to wind or unwind the vertical line. Through the above structure, the driving motor drives the roller shaft to rotate, and the vertical line drives the plumb bob to be lowered or raised, which is convenient for measurement without affecting the normal piling operation.

[0007] A fixed bracket is also provided on the top of the pile driver, and the front end of the fixed bracket is movably sleeved on the roller shaft. The roller shaft is limited by the fixed bracket without affecting the rotation of the roller shaft.

[0008] A through hole is provided at the front end of the fixed bracket, in which a bearing is coaxially fixed, and the inner ring of the bearing is fixedly sleeved on the roller shaft. Through the above structure, when the driving motor drives the roller shaft to rotate, the inner ring of the bearing rotates with the roller shaft, and the outer ring of the bearing is limited by the position of the fixed bracket, thereby limiting the position of the roller shaft.

[0009] An L-shaped support frame is fixed on the top of the pile driver, one end of the L-shaped support frame is fixed to the top of the pile driver, and the other end of the L-shaped support frame is sleeved on the driving motor. A limiting hole for passing a vertical line is opened on the L-shaped support frame, and the limiting hole is located above the left side or the right side of the square pile. The driving motor is fixed on the top of the pile driver through the L-shaped support frame, and the vertical line is limited to the left side or the right side of the square pile through the limiting hole, so that one vertical line is lowered along the front side of the square pile, and the other vertical line is lowered along the left side or the right side of the square pile, so as to measure the verticality of two adjacent faces of the square pile, and then obtain the verticality of the square pile.

The other end of the roller 2 is coaxially fixed with the inner end of the second turntable 1. Two vertical lines 7 are wound around the roller 2 between the first turntable 4 and the second turntable 1. The rotating shaft of the driving motor 5 drives the first turntable 4, the roller 2 and the second turntable 1 to rotate coaxially, so that the roller 2 rotates forward or reversely, and the vertical line 7 is wound or unwound. Through the above structure, the roller 2 is driven to rotate by the driving motor 5, and the plumb bob 8 is driven to be lowered or raised by the vertical line 7, which is convenient for measurement without affecting the normal piling operation.

[0014] In this embodiment, a fixed bracket 3 is further provided on the top of the pile driver. The fixed bracket 3 is composed of two fixed plates. The front ends of the two fixed plates extend above the front end of the pile driver. A through hole 31 with a diameter larger than the diameter of the roller 2 is opened at the front end of the fixed plate.
