Device for pulling and detaching plug at tail plate of tubular pile

Abstract

The invention discloses a device for pulling and detaching a plug at a tail plate of a tubular pile. The device comprises a rack and a turn-over, stretch-out and draw-back mechanical arm, the left end of the rack is provided with a bearing position for bearing the tubular pile, the turn-over, stretch-out and draw-back mechanical arm is arranged at the right end of the rack through a mounting assembly, the turn-over, stretch-out and draw-back mechanical arm is provided with a clamping assembly, the rack is provided with a collecting position below the turn-over, stretch-out and draw-back mechanical arm, and during operation, the turn-over, stretch-out and draw-back mechanical arm drives the clamping assembly to turn over and stretch out from bottom to top in a direction of the bearing position so as to clamp the plug, and then turns over and draws back from top to bottom so as to pull out the plug and drive the plug to turn over and move to a position above the collecting position such that the plug can be detached and collected. The device has the advantages of being simple and compact in structure, easy to manufacture and maintain and convenient and flexible to operate, greatly reducing labor intensity, greatly improving labor efficiency and facilitating plug recycling.

Description

technical field [0001] The invention mainly relates to the field of pipe pile production equipment, in particular to a pipe pile tail plate plug removal device. Background technique [0002] In current construction work, pipe piles need to be used in large quantities. During the production of pipe piles, there is a process that needs to pull out the plugs inserted at the ends of pipe piles before the centrifugal slurry of pipe piles is dumped. The following technical problems exist in the current plug extraction operation: [0003] One is that some of the existing technologies use manual operation to pull out, because the plug has a certain quality and is firmly inserted into the pipe pile, which makes pulling out not only high labor costs, but also high labor intensity and low work efficiency . [0004] The second is that in the prior art, when the plug is pulled out, there is cement slurry adhering to the plug, and when the plug is pulled out suddenly, the cement slurry...

AI Technical Summary

Problems solved by technology

[0003] One is that some of the existing technologies use manual operation to pull out, because the plug has a certain quality and is firmly inserted into the pipe pile, which makes pulling out not only high labor costs, but also high labor intensity and low work efficiency

[0004] The second is that in the prior art, when the plug is pulled out, there is cement slurry adhering to the plug, and when the plug is pulled out suddenly, the cement slurry is easily splashed out of the pipe pile. , the working environment is poor, and manual operation is also prone to safety accidents

[0005] The third is that in the prior art, no matter whether the plugs are pulled out manually or with simple tools, the plugs cannot be collected centrally, and the pulled out plugs are scattered randomly, which is not conducive to the cleaning and reuse of the plugs

[0006] The fourth is that in the prior art, some equipment directly pulls out the plug in a straight line backward. Since cement slurry is adhered to the plug, this straight-line removal makes the cement slurry adhered to the plug not be thrown off. Plugs are often mixed with residual pulp, causing pollution and damage to the plugs, and increasing the difficulty of subsequent cleaning of the plugs, which is not conducive to the reuse of the plugs

This method increases the cost of production and maintenance, and the second is that the clamping force of this structure is not strong, and because the plug has a certain quality and is firmly inserted into the pipe pile, it makes it difficult to pull out in a straight line. When clamping often slips, the pullout is unsuccessful and the plug is damaged

[0008] Sixth, in the prior art, the pipe piles are all hoisted and moved by lifting equipment (such as a crane), and some equipment does not use a positioning mechanism, resulting in the unfixed placement position of the pipe piles that are hoisted, which affects the subsequent plug removal. Accurate and fast

At the same time, some equipment does not leave a lifting space for the pipe piles, resulting in inconvenient operation and low work efficiency no matter when the pipe piles need to be hoisted when they are lifted and placed, or when the pipe piles need to be lifted away after the plug is removed.
