Description

Technical Field

[0001] The invention belongs to the technical field of electric wrench equipment, and in particular relates to an electric handheld bored pile steel conduit installation and removal device. Background Art

[0002] In construction projects, pouring refers to pouring the mixed concrete into the mold. The mold here can refer to the pile hole that has been dug or the column formwork and beam formwork that have been assembled. During the construction process, the pouring of concrete must meet the following requirements: use a concrete truck to transport the concrete directly to the construction site, and then use pumping and continuous pouring to pour the concrete; add retarding soil to the concrete to ensure that the quality of the concrete meets the design requirements; before sinking the conduit, the density and firmness of the conduit connection must be checked in detail to avoid leakage and air leakage.

[0003] However, the current bored pile steel conduit installation and disassembly devices on the market require two people to operate. One person holds a sickle wrench to clamp the steel conduit, and the other person hammers the back end of the wrench with a sledgehammer. This can easily cause hand injuries and has relatively low safety performance. At the same time, the traditional bored pile steel conduit installation and disassembly device cannot be quickly installed and disassembled when encountering a situation where mud and sand block the hole in the bored pile. Summary of the Invention

[0006] Preferably, a rubber pad with anti-slip protrusions is also pasted on the surface of the handle, the bottom of the handle is connected to a power cord fixed to the switch assembly through a wire, and the output end of the switch assembly is also electrically connected to the impact cylinder and the drive motor respectively through a wire.

[0007] Preferably, the shape of the splint is a quarter arc, and a locking mechanism that matches the splint is fixedly installed at the hinge between the mounting seat and the splint.

[0008] Preferably, a shaft sleeve is slidably sleeved on the surface of the impact cylinder, and the outer surface of the shaft sleeve is fixedly connected to the inner wall of the shell.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When encountering mud and sand blocking the hole in the bored pile, the user holds the handle with the rubber pad for anti-slip protection to avoid slipping during use. At the same time, it has good buffering properties, which is convenient for protecting the user's hands and improving the safety of use. The impact head is aimed at the blocked hole, and the finger presses the switch assembly to control the impact cylinder to open. The impact cylinder has the excellent characteristics of strong impact force, fast speed and low gas consumption. The impact cylinder drives the impact head to impact and clean the mud and sand blocked in the blocked hole, which is convenient for cleaning;

[0013] 2. The buffer assembly ensures the stability of the impact cylinder. When the impact cylinder slides due to rebound, the mounting plate brings the baffle closer to the fixed plate. The setting of the shaft sleeve facilitates the sliding of the impact cylinder during rebound. The shaft sleeve and the guide column ensure the axial stability of the impact cylinder and prevent position deviation or shaking. The baffle approaches the fixed plate under the action of the shock-absorbing spring, which can effectively buffer the rebound force of the impact cylinder and achieve good shock absorption effect.

[0014] 3. By setting up a driving motor, a splint, a discharge block, a gearbox and a chain, when it is necessary to dismantle the bored pile, first selectively install the discharge block on the multiple groups of threaded columns on the chain surface according to the diameter of the bored pile, manually rotate the splint to make it fit the surface of the bored pile to ensure that the discharge block is engaged with the slots on the bored pile, and then operate the locking mechanism to lock and limit the position of the splint, safely guide, control the drive motor to start, the drive motor transmits power to the main drive shaft through the gearbox, cooperates with the secondary drive shaft to drive the chain to rotate, and then the discharge block rotates and disassembles with the bored pile. One person can easily operate and complete the installation and disassembly action, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

The outer surface of the chain 13 is fixedly installed with evenly arranged threaded columns 16, and the surface of the threaded column 16 is threadedly connected to a discharge block 17 that cooperates with the limit plate 15.

[0021] Specifically, the handle 4 is further provided with a rubber pad 5 with anti-slip protrusions. The bottom of the handle 4 is connected to a power cord secured to the switch assembly 3 via a wire.
