Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of rod extraction, and more particularly, to a lever continuous self-locking type building temporary rod extraction device and a method of using the same. BACKGROUND

[0002] In foundation pit engineering, steel pipe railings, square steel railings, etc. are used for safety protection around the completed excavation foundation pit in advance. In order to ensure that the railings are installed firmly, the railings are generally inserted into the soil layer or the road surface base layer to a relatively deep depth. Therefore, in house building projects and municipal road projects, the problem of difficult removal of waste steel bars from the soil or the road surface base layer water stable layer often occurs. At present, when these rod-shaped temporary components are removed, workers usually use a hammer to directly hit them, loosen them, and then manually remove them, or directly use an electric tool to cut them, resulting in low construction efficiency and damage to the original road base layer and the rod to be removed.

[0003] In order to solve the technical problem of difficult removal of temporary rods, Chinese utility model patent CN214866082U discloses a steel bar pulling device for traffic engineering construction, which comprises two bottom seats symmetrically arranged on the top of the ground, a first hydraulic rod fixedly connected to the top of each bottom seat, a top plate fixedly connected between the top ends of the two first hydraulic rods, and a clamping mechanism arranged at the bottom of the top plate. The clamping mechanism includes a bent rod rotatably connected to the bottom of the top plate on the left and right sides, a vertical rod slidingly connected to the bottom of the top plate, the vertical rod extending through the top plate and extending to the top of the top plate, a horizontal block sleeved on the outer surface of the vertical rod, and a first mounting block fixedly connected to the top of the horizontal block on the outer surface of the vertical rod. In addition, Chinese invention patent CN111636714A discloses an adjustable angle type waste steel bar pulling device based on building construction, which relates to the field of building construction. The pulling device solves the problem that the current pulling device can only act on vertical steel bars and cannot fix the steel bars according to different angles and pull them along the angle of the steel bars by using a hoop clamping device and a jack. An adjustable angle type waste steel bar pulling device based on building construction, comprising a moving seat, two wheel frame plates fixedly arranged on the top of the moving seat, four groups of circular guide rods fixedly connected to the moving seat through bolts around the bottom of the wheel frame plate, a connecting rod, and a parallel rod. The pulling device provides an angle adjustment function through the setting of a pulling cylinder and an angle fixing nut, and the sliding table and the chuck are slidably arranged in the interior of the pulling cylinder.

[0004] The above patent technologies all fix the reinforcing steel bars through the clamping mechanism, and realize the pulling-up action of the reinforcing steel bar component by using the driving system to pull up in the vertical direction, but still have the following technical problems: (1) in the pulling-up process, if there is a vibration source to assist the loosening of the component to be pulled up, the pulling-up efficiency will be greatly improved, but the above patent technologies do not add a vibration source loosening function unit; (2) in the pulling-up process, the jacking force generated by the power source directly acts on the reinforcing steel bar, and in order to reduce the power consumption of the equipment, a pulling force amplification mechanism is added between the power source and the reinforcing steel bar; (3) in terms of the clamping position between the clamping unit and the component to be pulled up, the clamping unit needs to be driven to open and close in each pulling-up segment cycle to move down again to tighten the position of the component to be pulled up, so the working process is relatively complicated, and in addition, the above patent technologies are only suitable for pulling up reinforcing steel bar components, because the clamping unit does not have a clamping opening shape adjusting function, which makes it difficult to pull up components other than reinforcing steel types such as steel pipes, square steels and steel plates.
