Guard railing convenient to splice for mine exploding

Abstract

The invention discloses a guard railing convenient to splice for mine exploding. The guard railing includes a ground, a mounting rod, a fixing plate, short plates and a fixing button. A massif is arranged at one end of the ground and stone-drain is reserved on the surface of the ground; the mounting rod is fixed on the bottom of a supporting plate and a supporting rod is arranged on the back faceof the supporting plate; the fixing plate is arranged on the top of the supporting plate and a mounting block is arranged on the end of the fixing plate; the short plates are arranged on the front face of a steel plate, the a baffle is arranged on the side face of the steel plate, and the fixing button is arranged on the back face of the steel plate. According to the guard railing convenient to splice for mine exploding, the fixing plate is obliquely arranged, so that stones falling down on the fixing plate can creep down into a stone pit; larger impulsion can be produced to the supporting plate when exploding occurs, the supporting rod is driven to stretch in a supporting canister; a good buffer action is provided; a rotating structure is formed among the steel plate, the mounting block and a connecting plate, two guard railings are spliced together for use conveniently through the arrangement of a connecting frame.

Description

technical field [0001] The invention relates to the technical field of protective fences, in particular to a protective fence for mine blasting that is convenient for splicing. Background technique [0002] The guardrail is also called the crash guardrail, which is mainly used for the protection and protection of equipment and facilities in factories, workshops and warehouses. It is commonly made of steel, such as round steel pipes, square steel pipes or profiled steel plates, which can effectively reduce the time spent on shuttles when transporting equipment. It will bring damage to equipment and facilities caused by accidental impact, and also protect the logistics handling equipment itself. [0003] Protective devices will be used in the mine blasting process, which has a good protective effect on people and construction equipment. However, the existing protective fences have a relatively simple structure, which is not efficient enough to protect the blasting site, causin...
