Description

Technical Field

[0001] The invention relates to a scaffold anti-falling device, in particular to a novel eccentric shaft type gravity swing block anti-falling device for an attached scaffold, belonging to the technical field of scaffold anti-falling. Background Art

[0002] As technology develops and society progresses, the requirements for buildings have changed greatly not only in design, but also in height. Therefore, when building such a series of high-rise buildings, it is essential to use scaffolding, also known as climbing frames. Due to the high floors, automatic lifting scaffolding is used, which can freely climb up or down along the building. Compared with traditional scaffolding, it has been greatly improved in technology. During the scaffolding falling process, the scaffolding moves downward to drive the pendulum block to rotate downward and fit with the anti-fall block, which in turn drives the anti-fall block to rotate, and then clamps the crossbar on the scaffolding to prevent the scaffolding from falling further.

[0003] The currently used scaffolding anti-falling device has certain defects. It lacks the function of auxiliary clamping scaffolding, which makes the scaffolding easy to get stuck inside the L-shaped board during the falling process, thereby reducing the anti-falling effect of the scaffolding and making the anti-falling reaction speed slow. At the same time, the lack of installation mechanism makes it inconvenient to disassemble and assemble the L-shaped board, and then it is inconvenient to maintain the parts inside the L-shaped board. Therefore, in order to solve the above problems, a new eccentric shaft gravity pendulum block anti-falling device for attached scaffolding is proposed. Summary of the invention

[0006] The auxiliary clamping mechanism comprises a bolt rod, a nut, a spring 1, an arc-shaped plate and a ball bearing, wherein the bolt rod is installed at one end of the L-shaped plate, the nut is installed on the annular side surface of the bolt rod, and the outer side of the nut is fixedly installed inside the L-shaped plate, the spring 1 is fixedly installed inside the L-shaped plate, one end of the spring 1 is fixedly installed on the arc-shaped plate, more than two ball bearings are evenly installed at one end of the arc-shaped plate, one end of the bolt rod passes through the L-shaped plate and fits the arc-shaped plate, and the spring 1 is installed on the annular side surface of the bolt rod;

[0007] The mounting mechanism includes a fixed block, a T-block, a second spring and a clamping rod. The fixed block is fixedly mounted on one end of the L-shaped plate, and the fixed block is mounted inside the fixed plate. A clamping groove is provided at one end of the fixed block. A T-block is mounted on one end of the fixed block, and one end of the T-block extends into the fixed plate. A clamping rod is fixedly mounted on one end of the T-block, and the clamping rod is mounted inside the clamping groove. A second spring is mounted on the annular side surface of the T-block, and both ends of the second spring are respectively fixedly mounted on the T-block and the fixed plate.

[0008] Preferably, the auxiliary clamping mechanism is provided with two groups, the two groups of the auxiliary clamping mechanism have the same structure, and the two groups of the auxiliary clamping mechanism are respectively installed on two L-shaped plates.

[0009] Preferably, the mounting mechanisms are provided in two groups, the two groups of mounting mechanisms have the same structure, and the two groups of mounting mechanisms are symmetrically mounted on the fixing plate.

[0010] Preferably, two receiving grooves are symmetrically provided at the front end of the fixing plate, the fixing block is installed inside the receiving grooves, and a square groove is provided inside the receiving grooves.

[0011] Preferably, the card slot consists of a rectangular slot and a circular slot, a rectangular slot is opened at one end of the fixing block, a circular slot is opened inside the fixing block, and one end of the rectangular slot is connected to the circular slot, and the size of the cross section of the rectangular slot is the same as the size of the cross section of the card rod.

[0013] The beneficial effects of the present invention are:

[0014] 1. The first beneficial effect is that the vertical rod on the scaffold is placed between the L-shaped plate and the fixed plate, and then the bolt rod is screwed, and the bolt rod moves along the nut, and the movement of the bolt rod drives the arc plate to move, and then drives the ball to move and fit with the annular side of the vertical rod on the scaffold, and then the scaffold is auxiliary clamped and fixed, which solves the problem that the scaffold lacks the function of auxiliary clamping scaffolding, causing the scaffold to be easily stuck inside the L-shaped plate during the falling process, thereby reducing the anti-falling effect of the scaffolding and making the anti-falling reaction speed slow;

[0015] 2.
