Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction in building engineering, in particular to a movable anti-smashing device in a manually dug pile hole. Background Art

[0002] In the process of manual bored pile construction, during the slag discharge operation, it is easy for slag to fall, the bucket to fall out of control, and objects to fall from the hole mouth, which may cause injuries to people. Most of the existing manual bored pile protection devices are arranged at the hole mouth. For example, the patent document with the authorization announcement number CN209603528U discloses a detachable manual bored pile hole mouth protection device, which provides a cover plate with a hinge above the hole mouth. The cover plate can be flipped over. When opened, it is convenient for construction workers to enter and exit. When closed, it prevents ground debris from falling into the hole and injuring people. However, when slag is discharged during construction deep inside the pile hole, the device cannot prevent the slag in the slag bucket from falling or the bucket from falling out of control, which may cause injuries to the bottom of the hole. The patent document with the authorization announcement number CN211816204U discloses a protective frame for manually excavated piles, including a mounting frame arranged at the mouth of the bored pile, a protective bracket suspended on the mounting frame is provided in the inner cavity of the bored pile, a steel cable connected to the mounting frame is fixedly connected to the protective bracket, and a metal protective net is provided on the protective bracket. The protective frame connects the mounting frame and the protective bracket through a steel cable, and the metal protective net on the protective bracket prevents falling objects from the hole mouth from causing harm to the construction workers in the hole. However, every time the construction workers enter and exit the pile hole or perform slag removal operations, they need to pull the protective bracket out of the hole mouth, which is time-consuming and labor-intensive, and the operation is complicated and inconvenient to use. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem solved by the utility model is to provide a movable anti-smashing device for bored piles, which solves the problems that personal injury accidents are prone to occur during the construction of existing bored piles and the existing protective devices are complicated to operate and inconvenient to use.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a movable anti-smashing device in the hole of manually excavated piles, including a bottom frame and an anti-smashing frame. The bottom frame is a rectangular frame structure as a whole. Four adjustable screw top supports are arranged in the horizontal direction of the side of the bottom frame. Two U-shaped channel steel slide rails are arranged in parallel on the top of the bottom frame. A steel woven mesh is fixed on the upper surface of the anti-smashing frame. A pulley is provided at the bottom of the anti-smashing frame. The pulley cooperates with the U-shaped channel steel slide rail to slide the anti-smashing frame on the bottom frame. The horizontal area of ​​the anti-smashing frame is half of the bottom frame. A sliding support rod is also provided at the bottom of the anti-smashing frame in the vertical direction. Round steel lifting ears are provided on the bottom frame and the anti-smashing frame.

[0005] The beneficial effects of this program are:

[0006] 1. To protect construction workers, a bottom frame and a sliding anti-smashing frame are set. The adjustable screw top support provides lateral support to the bottom frame to ensure that the bottom frame is stably installed on the concrete retaining wall, thereby providing support for the anti-smashing frame. Cooperating with the steel woven mesh arranged on the anti-smashing frame, construction workers are constructing at the bottom of the anti-smashing frame. When debris falls, the bucket falls out of control, and objects fall from the hole, the anti-smashing frame blocks the falling objects to prevent injuries. A U-shaped channel steel slide rail is arranged on the bottom frame to cooperate with the pulley of the anti-smashing frame. The anti-smashing frame can slide on the bottom frame. When construction workers are constructing in the hole, the anti-smashing frame can be slid to the construction position to protect the construction workers. When construction workers need to enter and exit the pile hole or need to discharge slag, the anti-smashing frame slides to one side of the bottom frame. Construction workers are constructing or entering and exiting at the bottom of the anti-smashing frame. The slag bucket can pass through the side without the anti-smashing frame to perform slag discharge operations, preventing debris from falling and injuring people. The protection effect is good and the operation is flexible and convenient.

[0007] 2. Easy to install. When the position of the anti-smashing device in the pile hole needs to be adjusted, lift the bottom frame and the anti-smashing frame through the round steel lifting lugs, loosen the adjustable screw top support, lift the bottom frame and the anti-smashing frame to the predetermined height position, tighten the adjustable screw top support to install the bottom frame stably. It is easy to install and adjust and can be used repeatedly.

[0008] Furthermore, the bottom frame, the adjustable screw rod support and the U-shaped channel steel slide rail are welded together to improve the integrity of the bottom frame, making it more firm and reliable when used.

[0009] Furthermore, both ends of the U-shaped channel steel slide rail are provided with limit steel plates, and the pulley stops sliding when it slides to the limit steel plates, effectively preventing the pulley from sliding out of the slide rail.

[0010] Furthermore, an additional keel is welded inside the anti-smash frame, which effectively improves the bearing capacity of the anti-smash frame.

[0011] Furthermore, the bottom frame and the anti-smashing frame are both made by welding 50×50×3mm square steel pipes, which have high strength and are easy to obtain.

[0012] Furthermore, the steel woven mesh is woven with steel wires of 3 mm in diameter and has a mesh size of 1.5 cm, which effectively prevents debris from falling and injuring people. BRIEF DESCRIPTION OF THE DRAWINGS
