Pulley-clip scaffold with cross rod falling-off-preventing self-locking device and mounting and dismounting method of pulley-clip scaffold

Abstract

The invention provides a pulley-clip scaffold with a cross rod falling-off-preventing self-locking device and a mounting and dismounting method of the pulley-clip scaffold. The pulley-clip scaffold with the cross rod falling-off-preventing self-locking device comprises a vertical rod and a cross rod; the ends of the cross rod are connected with limiting pins correspondingly, and the vertical rod is connected with a pulley-clip disc; through holes for allowing the limiting pins to penetrate through are formed in the pulley-clip disc, and grooves are formed in the limiting pins; the pulley-clipscaffold further comprises self-locking blocks which are movably connected into the grooves and contained in the grooves when the limiting pins pass through the through holes; and the self-locking blocks are rotated or popped out from the grooves after the limiting pins penetrate through the through holes and lock and fix the limiting pins into the pulley-clip disc. According to the pulley-clip scaffold, the self-locking blocks, the limiting pins and the pulley-clip disc constitute the self-locking device jointly, only the self-locking blocks need to be inserted into the pulley-clip disc alongwith the limiting pins, the self-locking blocks are rotated or popped out from the grooves again, then the limiting pins can be firmly limited in the pulley-clip disc, the cross rod is prevented fromfalling off, operating is easy and convenient, manpower is saved, forgetting and omission are not prone to occurring, and thus construction safety is ensured.

Description

technical field [0001] The invention relates to the field of construction, in particular to a wheel-buckle scaffold with a self-locking device for preventing falling off of a cross bar and an installation and disassembly method thereof. Background technique [0002] Compared with the traditional fastener-type steel pipe scaffolding, the wheel-buckle scaffolding has the characteristics of large bearing capacity, fast construction speed, strong stability, and easy site management. It is currently widely used in engineering. [0003] As a supporting frame, the wheel buckle scaffold plays a role of bearing and supporting and provides an operating platform for construction personnel to work in different parts, so the safety of the scaffold is very important. [0004] At present, the wheel buckle-type scaffolding in the market uses a hole at the bottom of the bolt for the crossbar. After the pin head is inserted into the button hole, a lock card is inserted into the round hole at ...
