Description

Technical Field

[0001] The utility model relates to the technical field of earthwork protection devices, in particular to an earthwork accumulation protection device for building earthwork excavation. Background Technique

[0002] During the process of building construction, it is necessary to excavate and build a foundation pit. During the process of excavating and building the foundation pit, a lot of earthwork will be generated. When the earthwork transportation speed cannot keep up with the excavation and construction speed, the excavated earthwork will be piled up on the edge of the foundation pit. However, due to factors such as the depth of the foundation pit and rainy weather, the earthwork on the edge of the foundation pit is prone to landslide into the foundation pit. Therefore, it is necessary to cover and reinforce the earthwork.

[0003] The existing reinforcement method is generally to cover the earthwork with a mesh cloth. When laying the dust-proof covering net, the dust-proof covering net is simply placed on the outer wall of the earthwork pile. If the wind blows, the dust-proof covering net will be lifted, resulting in poor stability during its covering.

[0004] Therefore, we propose an earthwork accumulation protection device for building earthwork excavation. Content of the Utility Model

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides an earthwork accumulation protection device for building earthwork excavation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme. An earthwork accumulation protection device for building earthwork excavation includes a dust-proof covering net. A positioning mechanism is arranged on the dust-proof covering net. The positioning mechanism includes a positioning connecting plate. The positioning connecting plate is arranged on the lower side wall surface of the dust-proof covering net. A positioning clamping plate that can be limited is fixedly installed on the upper side wall surface of the positioning connecting plate. A positioning sleeve that penetrates through its upper and lower wall surfaces is fixedly installed on the upper side wall surface of the dust-proof covering net. The outer wall of the positioning clamping plate is adapted to the inside of the positioning sleeve, and the outer wall of the positioning clamping plate is movably clamped into the inside of the positioning sleeve. A positioning connecting groove that can be limited is fixedly installed on the upper side wall surface of the dust-proof covering net. The outer wall of the positioning connecting groove penetrates through the upper and lower wall surfaces of the dust-proof covering net. A positioning connecting rod that can be limited is fixedly installed on the upper side wall surface of the positioning connecting plate. The outer wall of the positioning connecting rod is adapted to the inside of the positioning connecting groove, and the outer wall of the positioning connecting rod is movably clamped into the inside of the positioning connecting groove. A positioning cone that can be rotated is arranged inside the positioning clamping plate.

[0007] Preferably, a matching fixed connecting block is arranged inside the positioning clamping plate. The fixed connecting block is rotatably installed inside the positioning clamping plate. The positioning cone is fixedly installed on the right side wall surface of the fixed connecting block in a detachable manner. Friction sheets for increasing frictional resistance are fixedly installed between the front and rear wall surfaces of the fixed connecting block and the corresponding wall surfaces inside the positioning clamping plate.

[0008] Preferably, a positioning chute for positioning is provided on the front side wall surface of the positioning sleeve. A positioning block for limiting is arranged inside the positioning chute, and the outer wall of the positioning block movably penetrates through the front side wall surface of the positioning plate.

[0009] Preferably, the inside of the positioning plate and the positioning connecting plate communicate with each other. A connecting sliding rod is movably installed inside the positioning connecting plate. The outer wall of the connecting sliding rod movably penetrates through the front side wall surface of the positioning connecting plate, and a fixed connecting plate is fixedly installed on the rear side wall surface of the connecting sliding rod.

[0010] Preferably, the fixed connecting plate is arranged in a vertical state. The outer wall of the fixed connecting plate extends into the inside of the positioning plate. The positioning block is fixedly installed on the front side wall surface of the positioning chute. Elastic elements are fixedly installed on the wall surfaces of the fixed connecting plate and the positioning connecting plate cavity close to each other.

[0011] Preferably, the outer wall of the connecting sliding rod movably passes through the inside of the elastic element. The front side wall surface of the positioning block is an inclined surface, and the inclined surface is in a state of decreasing from back to front in sequence.

[0012] The utility model provides an earthwork stacking protection device for building earthwork excavation, which has the following beneficial effects:

[0013] 1. For the earthwork stacking protection device for building earthwork excavation, during the use of the utility model, when it is necessary to cover and protect the earthwork heap, the upper side wall surface of the dust-proof covering net can be attached to the outer wall of the earthwork heap, and then the positioning cone is rotated until the positioning cone is in a vertical state, and then the positioning cone is nailed into the earthwork heap to improve the stability of the dust-proof covering net during covering. In addition, the dust-proof covering net can be pulled downward until the positioning connecting rod and the positioning connecting groove are separated, and at the same time, the positioning sleeve and the positioning plate are separated, realizing the disassembly of the positioning block, which is convenient for disassembly and replacement.

[0014] 2. For the earthwork stacking protection device used in building earthwork excavation, during the use of this utility model, by pressing the connecting slide rod backward, the fixed connecting plate starts to move backward, and the positioning block will move backward until it separates from the positioning chute. At this time, the positioning connecting plate can be pulled downward to separate it from the dust-proof covering net. Limitation can be carried out between the positioning chute and the positioning block to improve the stability when the dust-proof covering net is connected to the positioning connecting plate. When connecting the dust-proof covering net and the positioning connecting plate, during the process of inserting the positioning card plate into the positioning sleeve, the inclined surface of the positioning block contacts the inner wall of the positioning sleeve, and the positioning block is forced to move backward. The fixed connecting plate drives the connecting slide rod to move backward, and the elastic element will be stretched. Until the positioning block moves to the position of the positioning chute, the elastic element will contract and return to its original state. The positioning block will move forward and be inserted into the positioning chute. Without manually operating the connecting slide rod, the connection between the positioning chute and the positioning block can be realized, which is convenient for the use of the device.
