Abstract
The present invention relates to the coverings of station bracing in open cut construction section Dense mesh screen, nerve of a covering running gear between the station support of specially a kind of manual hand manipulation, the device includes aluminium alloy conduit (1), the fixinig plate (2) of fixed aluminium alloy conduit (1), fixinig plate (2) is anchored in the screw (3) of track girder concrete side, reinforce the plastic dowel sleeve (4) that screw (3) are contacted with concrete, the pulley (5) being installed in aluminium alloy conduit (1), it is connected to Dense mesh screen (8) of the pulley (5) as nerve of a covering on foundation pit, it is fixed on the cap (10) that the anti-limited slip wheel in aluminium alloy conduit (1) both ends (5) skids off.Compared with prior art, the configuration of the present invention is simple, low cost, it is easily operated, it can be operated outside foundation pit protective fence of standing by two workers using 2.5m long band hook bamboo pole, worker falls the security risk of foundation pit when can avoid foundation pit covering, the covering suitable for station bracing in open cut construction section.
Description
Technical field
The present invention relates to dust-proof Covering domain, nerve of a covering row between the open-cut station support of especially a kind of manual hand manipulation
Walking apparatus.
Background technique
Xi'an municipal government is to carry out Dust Improvement, iron hand haze work, it is desirable that subway work project must carry out exposed soil hundred
Divide hundred coverings, currently, generally using Dense mesh screen similar in foundation pit size, both ends use rope to be tied to branch for covering on station pit
Support beam closes on fixed point, needs worker station margin of foundation pit to carry out Dense mesh screen covering or pack up, because standing in deep basal pit marginal operation, deposits
The security risk fallen in foundation pit in operation, and take time and effort, it is very big to the efficiency and security risk presence of foundation pit covering
Restriction.
Summary of the invention
The object of the invention is to provide the open-cut station support of manual hand manipulation a kind of to overcome above-mentioned insufficient
Between nerve of a covering running gear, the apparatus structure is simple, easily operated, and worker can be made to stand outside foundation pit protective fence and carry out foundation pit covering behaviour
Make, and easy to operate, manpower can be saved well, covering is time-consuming short, and Safety assurance measures are good.
The purpose of the present invention can be achieved through the following technical solutions:
Nerve of a covering running gear between a kind of support of open-cut station, including Dense mesh screen (7), Dense mesh screen (7) both ends pass through activity
Steel loop (6) connects pulley (5), and pulley (5) is mounted in walking slideway, and walking slideway is anchored in the interior of two track girders of foundation pit
Side, walking slideway end are equipped with hook (9), and the link (8) of Dense mesh screen (7) end can be hung on hook (9).
Dense mesh screen (7) two sides are equipped with row's steel ring hole (11), movable steel loop (6) connection steel ring hole (11) and pulley (5).
Slideway of walking includes aluminium alloy conduit (1) and fixinig plate (2), and fixinig plate (2) is vertically mounted on aluminium alloy conduit (1)
The back side, fixinig plate (2) is mounted on track girder medial surface by bolt (3).
The both ends of aluminium alloy conduit (1) have cap (10).
Steel ring hole (11) spacing 0.25-0.35m, diameter 0.5-1.5cm.
Fixinig plate (2) installs one every 0.5-.07m.
Compared with prior art, the beneficial effects of the present invention are embodied in:
(1) structure is simple, low cost, easily operated；
(2) Dense mesh screen is connected on pulley using movable steel loop, and when Dense mesh screen breakage can be carried out by disassembly activity steel loop
Replacement is replaced convenient and efficient；
(3) Dense mesh screen walking slideway is fixed on concrete side, avoids and interferes to other process construction.And it walks
Conduit is aluminium alloy, is not easy to corrode, and can be used for a long time；
(4) worker stands foundation pit fence outside using band hook two people of bamboo pole cooperation, can will cover net unfolding and pack up, avoid
Operation, falls into the security risk in foundation pit by the foundation pit of station.
Detailed description of the invention
Attached drawing 1 is the general structure schematic diagram of apparatus of the present invention；
Attached drawing 2 is the side structure schematic diagram of apparatus of the present invention；
Attached drawing 3 is the top view of nerve of a covering device in the present invention；
Figure label: 1 it is aluminium alloy conduit, 2 is fixinig plate, 3 is bolt, 4 is plastic dowel sleeve, 5 is pulley, 6 is living
Dynamic steel loop, 7 be Dense mesh screen, 8 be A50 steel loop, 9 be link up with, 10 be cap, 11 be 1cm steel ring hole.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Nerve of a covering running gear between the open-cut station support of manual hand manipulation a kind of, as shown in Figure 1, 2, 3, the device
Composition are as follows:
Nerve of a covering: including Dense mesh screen 7, the steel ring hole 11 of a 1cm is arranged every 0.3m for fixed both ends, using movable steel loop
It is connect in 6 sets of steel ring holes 11 with pulley 5, A50 steel loop 8 is installed at 7 both ends of Dense mesh screen, for hanging over the extension of side wall after Dense mesh screen expansion
On hook 9.
Walking slideway: the fixinig plate 2 including aluminium alloy conduit 1 and fixed aluminium alloy conduit 1, fixinig plate (2) are anchored in rail
Road beam concrete side is fixed by bolt and 3 with the plastic dowel sleeve 4 in concrete, the cunning being installed in aluminium alloy conduit 1
Wheel 5, the cap 10 that 1 both ends of aluminium alloy conduit have anti-limited slip wheel 5 to skid off.The aluminium alloy conduit 1 is fixed on two siding track of foundation pit
Road beam sides is in same level axis, 1 back side of aluminium alloy conduit, one fixinig plate 2 of every 0.6m right angle setting, fixinig plate 2
It is anchored in track beam sides by bolt and plastic dowel sleeve 4, is mounted to walking slideway.
Specific application method are as follows: on the hook 9 that the steel loop 8 of Dense mesh screen 7 is hung over to walking slideway one end, 7 liang of Dense mesh screen
The steel ring hole 11 of side by steel loop 6 connect pulley 5, worker stand foundation pit fence outside using band hook two people of bamboo pole cooperation, can will
It covers net unfolding and packs up.
The present invention not only can guarantee foundation pit closing Dense mesh screen covering, but also can prevent covering Dense mesh screen by the foundation pit of worker station from crashing into base
The security risk in hole, structure is simple, easy to operate, and foundation pit Dense mesh screen covers very between open-cut station supporting beam.
