Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to a foldable edge protection device. Background Art

[0002] At present, most of the guardrails on the edge of the foundation pit at the construction site are steel pipe fastener type or integrated guardrails. However, in some special parts, the above guardrails cannot meet the safety protection requirements. For example, when there are operations such as taking soil and digging on the edge of the foundation pit or on the trestle, the guardrails with a fixed height will hinder the normal use of mechanical equipment; in this case, it is often necessary to remove the installed guardrails, but the excavation work will continue to change places as the excavation process progresses, which leads to frequent removal and installation of edge protection. The existing edge protection device installation and removal process is relatively cumbersome, which not only wastes the workers' energy, but also increases the construction time cost. Utility Model Content

[0003] In order to overcome the problem that the fixed height of the existing foundation pit edge protection will hinder the normal operation of mechanical equipment, for example, when there are earth-taking and digging operations on the foundation pit edge and trestle; the embodiment of the utility model provides a foldable edge protection device. The technical solution is as follows:

[0004] A foldable edge protection device comprises a plurality of rectangular columns and a connecting plate connecting two adjacent columns, wherein the columns comprise a plurality of sections, and one side surface of adjacent sections is hinged by a hinge, and a locking structure is correspondingly arranged on the side surface of the column opposite to the hinge; slide grooves are symmetrically arranged on both side surfaces adjacent to the hinge of each section of the column, and the cross section of the slide groove is T-shaped, and both ends of the connecting plate match the slide grooves and are inserted into the slide grooves, and the multi-section hinged columns enable the device to be flexibly adjusted when the height of the edge protection needs to be adjusted, so as to avoid affecting the construction due to the fixed height, and the locking structure can be used to quickly adjust the height, thus saving construction time.

[0005] Furthermore, the locking structure includes two ear plates respectively fixed on two adjacent sections of the column, and the two ear plates are provided with corresponding through holes, and the two ear plates are connected by an L-shaped insertion rod passing through the through hole. The lower end of the insertion rod is provided with an R-type pin, which can prevent the insertion rod from falling off and is more convenient for insertion.

[0006] Furthermore, a column foot is provided at the lower end of the column, and the column foot includes a base fixed to the ground by rivets and a rectangular tube fixed to the upper end surface of the base, and the lower end of the column is inserted into the rectangular tube and fixed by a bolt provided on a side.

[0007] Furthermore, the hinges and the locking structures on the same side of the column are arranged alternately, and the alternating arrangement can make it easier to fold multiple sections of the column when lowering the height of the device.

[0008] Furthermore, a support plate is fixed to the upper end of the connecting plate, and both ends of the support plate are located between adjacent sections of the column.

[0009] Furthermore, there is a spacing between adjacent sections of the column, and the spacing is equal to the thickness of the support plate. The thickness of both ends of the support plate just adapts to the spacing between adjacent sections of the column, and can provide a certain supporting force for multiple sections of the column.

[0010] Furthermore, the connecting plate is a perforated mesh plate, which saves resources while ensuring a certain strength.

[0011] Furthermore, a reinforcing support is fixed to one side of the connecting plate to prevent the connecting plate from bending due to being too long.

[0012] The beneficial effects of the technical solution provided by the embodiment of the utility model are: the device has a simple structure, is easy to use and can be adjusted quickly, which can not only effectively avoid the problem of frequent installation and removal of foundation pit edge protection, but also effectively save workers' energy and reduce construction time costs.
