Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and particularly relates to an openable dustproof canopy track device. Background Art

[0002] Dust control at construction sites is a major management focus in the construction field. During the foundation pit construction phase, dust control is very difficult due to the influence of earth-moving vehicles and various excavations and demolitions. Traditional dust control measures, such as green net covering and fog cannons, have limited dust control during the foundation pit construction phase, and dust control measures often fail to meet standards.

[0003] CN218014785U discloses a dustproof canopy device, which aims to provide a method to overcome the defects of the prior art in that the laying and folding process of the foundation pit dustproof net is time-consuming and labor-intensive, inconvenient to operate, and has potential safety hazards, thereby providing a dustproof canopy device that saves time and effort, has low difficulty in operation, is highly efficient, and is safe and efficient. The technical scheme: includes at least one dustproof canopy unit, the dustproof canopy unit includes: a support assembly, a canopy assembly, a plurality of groups of sliding assemblies, and a transmission assembly; the support assembly includes a first slide rail and a second slide rail arranged on both sides of the construction area; one end of the sliding assembly is slidably connected to the first slide rail or the second slide rail, and the other end is connected to the canopy assembly; the transmission assembly includes a drive assembly and a transmission rope, the transmission rope is arranged around the canopy assembly and fixedly connected to any one group of sliding assemblies located at the end of the first slide rail or the second slide rail, and the transmission rope slides through the remaining sliding assemblies. That is, the track device is processed into a guide rail using steel sections, and the pulley block is horizontally arranged between the two side guide rails and connected to the wire rope to open and close the canopy device. The problem with this dustproof canopy track device is that the track pulley block is prone to eccentricity and misalignment, which leads to low efficiency in the opening and closing of the canopy, and fails to achieve the effect of ensuring the construction efficiency of the dustproof canopy device while ensuring safety and stability. Utility Model Content

[0004] The utility model is a track device for an openable dustproof canopy developed to solve the problem of dust pollution in the process of foundation pit construction. It adopts standardized components, changes the design and installation form of the track pulley block, ensures the center of gravity of the track pulley block is stable and not offset, is safer and more reliable, thereby improving the construction efficiency of the dustproof canopy device.

[0005] The technical solution of the utility model is the openable dustproof canopy track device, which is special in that it includes a track pulley block and a track. The track pulley block consists of a U-shaped frame, and the U-shaped frame has pulley brackets symmetrically arranged axially and radially at its bottom end and the open end, and the pulley brackets are respectively pivotally provided with pulleys; the pulleys in the track pulley block are respectively arranged on both sides and the top of the track.

[0006] Preferably, the bottom of the track is fixed to an I-beam track support column and fixed to a long side support structure of the foundation pit.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] (1) The utility model is a standardized tool which can reduce the pollution of construction environment and is simpler, more practical and cost-saving.

[0009] (2) The track device of the skylight device described in the utility model is safer and more stable during operation. Compared with traditional dust-proof processes and existing dust-proof skylight technologies, it reduces the increased maintenance costs caused by jamming, misalignment, etc. during the operation of the track device.

[0010] ⑶ The utility model has a simple construction process, can be installed and formed in one time, and can quickly open and close the dustproof canopy. The components are cut and processed with I-beams, steel plates and other materials. The high-strength materials can be recycled to other locations, which better reduces construction waste and is green and environmentally friendly.

[0011] (4) The utility model adopts multiple pulleys to form a stable track pulley group. The pulley groups are fixed on both sides and the top of the track in different directions at the same time. The pulley will not have uneven friction force with the track, which reduces the friction of the track and ensures the stability of the center of the track pulley group, thereby improving the opening and closing efficiency of the dustproof canopy.

[0012] (5) The pulley block of the utility model is formed in one step, and is connected to the track in a horizontal socket-type manner, which is convenient for installation and disassembly, thereby improving the construction efficiency of the dustproof canopy operators.
