Background
In the construction engineering construction process, the fence, the guardrail, the steel template and the like all need to be fixed by knocking in the ground by using the steel bars, and in addition, control points, monitoring points and the like are used for measurement control and the like by using the steel bars inserted into the ground, so that the condition of using the steel bars for assistance is various. After the auxiliary steel bars are used up, most of the auxiliary steel bars are buried underground and taken out to be very difficult, the steel bar heads which leak out of the ground are cut directly in the actual operation process, the auxiliary steel bars are wasted after being buried under the ground, the steel bars which leak out of the ground can be directly knocked into the ground to be wasted, the waste is extremely serious, the project cost is increased, and the auxiliary steel bars are contrary to the environmental protection prospect of national carbon peaks.
The problem that current reinforcing bar instrument exists to use the effort inefficiency more, and the application of application number 201920093312.X provides a reinforcing bar instrument of extracting, through setting up lower clamping part and last clamping part interval, realizes that the reinforcing bar degree of buckling of extracting is little, and reinforcing bar extracts labour saving and time saving, has improved work efficiency. However, if the steel bar with a deeper embedding depth is encountered during the use of the application, the steel bar is difficult to directly pull out by the tool, so that the operation is laborious and the working efficiency is low.
Disclosure of utility model
Aiming at the defects of the prior art, the problem of low use cost and efficiency of the steel bar pulling tool is solved.
The utility model provides a special tool for pulling out reinforcing steel bars, which comprises a clamping assembly and a supporting assembly serving as a lever fulcrum of the clamping assembly, wherein the supporting assembly comprises a supporting frame and a supporting sleeve, and a rotatable first sleeve is arranged at the upper end of the supporting frame.
Further, the clamping assembly comprises a force transmission beam, and a rotatable clamping head is arranged at one end of the force transmission beam.
Further, the clamping head comprises an annular connecting piece, a rotatable second sleeve is arranged at the upper end of the connecting piece, a steel bar gripper is arranged at the lower end of the connecting piece, and the second sleeve is connected with a force transmission beam.
As a preferable scheme, the steel bar gripper is a triangular clamping piece.
As a preferred scheme, the other end of the force transmission beam is provided with an operating handle.
As a preferable scheme, the force transmission beam is made of deformed steel bars with diameters of 25mm, 28mm or 30mm, and the size of the steel bars to be pulled out is selected according to the requirement.
The utility model has the beneficial effects that:
The supporting component provides supporting points for the clamping component to realize an erected working posture; the operating workers press down the operating handles forcefully, at the moment, acting force is transmitted to the clamping heads along the force transmission cross beam, and meanwhile, the acting force is amplified by a plurality of times under the action of the supporting component; the acting force amplified by a plurality of times is transferred to the steel bar grab; at this moment, the to-be-pulled reinforcing steel bars on the ground are inserted into the vertex angles of the triangular reinforcing steel bar grippers, the reinforcing steel bar grippers amplify the acting force for the to-be-pulled reinforcing steel bars by several times, the to-be-pulled reinforcing steel bars are easily pulled out, and if the to-be-pulled reinforcing steel bars are longer, the reinforcing steel bars can be easily pulled out by repeating the process.
