Description

Technical Field

[0001] The utility model relates to the technical field of column reinforcement planting drilling, in particular to a structural column reinforcement planting drilling device. Background Art

[0002] The traditional method of drilling holes for rebar planting in structural columns under beams and slabs is to use a bamboo pole or wooden stick with an electric drill fixed on top. Workers hold the bamboo pole or wooden stick and drill holes in the bottom of the beam and slab with an electric drill, or workers use a stepladder to climb up and then hold the electric drill to drill holes. These two methods have the following problems: first, the drilling depth cannot be guaranteed; second, the positioning is inaccurate; third, there are major safety hazards, which seriously affect the quality of rebar planting in structural columns. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a structural column rebar embedding drilling device with accurate positioning, controllable depth and safe operation.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A structural column rebar drilling device comprises a movable platform, a manual lifting assembly is provided on the movable platform, an electric drill is installed on the manual lifting assembly, the manual lifting assembly comprises a vertically arranged gear rod, the cross-section of the gear rod is rectangular, the gear rod is slidably arranged in a guide frame on the movable platform, an opening is provided on the side wall of the guide frame, a circular shaft is fixedly installed at the opening, a circular shaft is connected to a circular disc, the circular disc is provided with helical teeth cooperating with the gear rod at a position opposite to the opening, a gear is coaxially provided on the other side, a wrench is also provided on the circular shaft, a connecting rod is connected to the wrench, and a locking block cooperating with the gear is fixedly installed on the end of the connecting rod.

[0006] To use it, move the mobile platform to the drilling position, secure the electric drill to the gear rod, engage the locking block with the gear, and pry the wrench, which in turn drives the disc and its spiral teeth to rotate. By cooperating with the gear rod, the electric drill rises to complete the drilling. After drilling is completed, rotate the connecting rod, reverse the locking block to engage the gear, and pry the wrench in the opposite direction to complete the lowering of the electric drill. This solution eliminates the need for manually holding an auxiliary rod to drill, and does not require personnel to climb high, making it easy and safe to operate.

[0007] As an optimization, a positioning component is provided on the mobile platform. The positioning component is a laser pen provided on the mobile platform. The laser pen is vertically coaxially arranged with the electric drill.

[0008] In this way, pre-positioning can be performed before drilling to ensure the accuracy of the position when drilling.

[0009] As an optimization, a mounting plate is also provided on the movable platform, and a plurality of through holes are evenly arranged circumferentially on the mounting plate. Two positioning rods are provided in the through holes, and the positioning rods are respectively arranged above and below the wrench, and the axis between the plurality of through holes coincides with the axis of the circular shaft.

[0010] In this way, the rotation stroke of the wrench can be controlled, and the drilling depth can be controlled by controlling the number of prying to avoid depth failure. The position of the in-place rod is adjustable, and drilling requirements of different depths can be used.

[0011] As an optimization, the mobile platform is provided with running wheels, and the running wheels are provided with brake discs.

[0012] In this way, while ensuring that the mobile platform can move, after positioning, the drilling process will not move, ensuring the accuracy and safety of the drilling operation.

[0013] As an optimization, the circular shaft is connected to the guide frame via a mounting bracket.

[0014] As an optimization, a strapping belt is provided on the top of the gear rod.

[0015] Like this, can be convenient to take out and install the electric drill, and operation is convenient.

[0016] In summary, the structural column rebar embedding drilling device has the advantages of accurate positioning, controllable depth and safe operation. BRIEF DESCRIPTION OF THE DRAWINGS
