Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings. see Figure 1 to Figure 9 .

[0032] like Figure 1 to Figure 3 As shown, a hanging object opening and closing simultaneously with a cover plate and a guardrail includes a cover plate 20 and a guardrail 30 . The cover plate 20 and the guardrail 30 are opened to form a fence around the object hanging hole, and the cover plate 20 and the guardrail 30 are connected in a linkage manner.

[0033] Described guardrail 30 is made up of several modules 300, as Figure 4 As shown, each module 300 includes a base 31 , several columns 32 and several beams 33 . The bottom of each column 32 is pivotally connected to the base 31 , that is, the column 32 can rotate around the base 31 , and the beam 33 and the column 32 are cross-connected to form the main body of the guardrail module 300 . Column 32 plays a main supporting role, prevents guardrail 30 from toppling along t...

Abstract

The invention discloses a hoisting hole. The hoisting hole comprises a cover plate and a guardrail and further comprises a linkage device. The guardrail is a folding mechanism, and the linkage device is respectively connected with the cover plate and the guardrail. While the cover plate is opened or closed, the guardrail is driven to be opened or closed through the linkage device. Production cost is saved, and the device is fast to operate and easy to obtain.

Description

technical field [0001] The invention relates to a hole for hanging objects on a floor of a multi-storey building, in particular to a guardrail device which is opened and closed synchronously with the cover plate of the hole for hanging objects. Background technique [0002] In high-rise buildings and factory buildings, most of them are equipped with openings or openings for moving in or moving out equipment, that is, hanging holes. In the existing hanging object hole, when the hanging object hole is opened to the fully opened state, the fences on its four sides are composed of opened cover plates and guardrails. The guardrails currently used are made of laser-cut steel plates, which are very expensive, heavy, and time-consuming to open. Moreover, in order to reserve the installation position of the guardrail, processes such as slotting must be performed on the cover plate, which greatly affects the processing and design of the cover plate and increases a lot of costs.
