Description

A kind of adjustable steel shelf structure boom hoisting

Technical field

This utility model relates to construction engineering technical field, particularly relates to boxlike steel frame construction unit welding technical field, is specifically related to a kind of adjustable steel shelf structure boom hoisting.

Background technology

At building field, there is the Factory Building of a kind of steel lattice box structure at present, it is that the agent structure constituting Factory Building floor is divided into several boxlike unit, each boxlike unit is groined type steel frame construction as shown in Figure 1, multiple boxlike unit mutually weld together and form the agent structure of Factory Building floor, concrete grouting is used to go out floor to complete the construction of Factory Building again in this agent structure, this modular structure can realize the function of Multi-layer synchronous construction, and current this new construction method the most progressively becomes the main construction method of steel-structure factory building.

But, during this construction method, there is one compare stubborn problem, this problem is mainly the lifting to steel construction unit, mutually it is spliced owing to steelframe as shown in Figure 1 uses the T-shaped steel plate of upper and lower two-layer, need after lifting to maintain lifting state, then it is connected to each other by punching and bolt, finally weld again, in traditional hoisting process, the general suspender used is steel wire rope, need in advance steelframe to be carried out the winding of steel wire rope, lift the most again, remove the most manually after having welded, have clearly a need for expending substantial amounts of manpower and time, not only result in duration of a project growth, also add construction cost.

Utility model content

This utility model aims to provide a kind of adjustable steel shelf structure boom hoisting, and hand labor intensity steel wire rope hoisting process in the presence of traditional to solve steel frame construction employing is big, human input is many, efficiency is low, cost is high and duration affected problem.

This utility model is achieved by following technical solution:

A kind of adjustable steel shelf structure boom hoisting, including framework, before and after framework, two side roof parts are all connected with rack rails, frame mid portion is connected with some slide bars being arranged in parallel by fixing seat, slide bar is paralleled with rack rails, and slide bar is socketed with slide, and slide bar is provided with the slide plate perpendicular with slide bar through slide and slide bottom, slide plate end is provided with telescoping drive mechanism, and slide plate bottom is provided with the claw of vertically layout.

Described telescoping drive mechanism includes that motor, motor output end are provided with rotating shaft, and shaft end is connected with gear, and gear is placed in the gear grooved that slide plate end is offered, and gear is wanted to engage with described rack rails.

Described frame mid portion is provided with reinforcing plate, and reinforcing plate direction is perpendicular with slide bar.

Described slide bar at least two.

The beneficial effects of the utility model are:

Compared with prior art; the adjustable steel shelf structure boom hoisting that this utility model provides; drive two pieces of slide plates mutually to draw close or separate by telescoping drive mechanism and realize spacing regulation; and then realize the clamping to various sizes of steelframe and lifting; compared to traditional lifting mode; this utility model has that simple in construction, simple operation, stability is strong, automaticity advantages of higher, and then hand labor intensity and lifting time can be greatly reduced, and is effectively increased lifting efficiency reduction of erection time.

In figure: 1-framework, 2-rack rails, 3-slide plate, 4-slide bar, 5-slide, 6-fixes seat, 7-motor, 8-rotating shaft, 9-gear, 10-gear grooved, 11-claw, 12-reinforcing plate.

Detailed description of the invention

Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but required protection domain is not limited to described；

As Figure 2-3, the adjustable steel shelf structure boom hoisting that this utility model provides, it includes framework 1, before and after framework 1, two side roof parts are all connected with rack rails 2, are connected with some slide bars 4 being arranged in parallel by fixing seat 6 in the middle part of framework 1, and slide bar 4 is paralleled with rack rails 2, slide 5 it is socketed with on slide bar 4, slide bar 4 is provided with the slide plate 3 perpendicular with slide bar 4 through slide 5 and slide 5 bottom, and slide plate 3 end is provided with telescoping drive mechanism, and slide plate 3 bottom is provided with the claw 11 of vertically layout.

Described telescoping drive mechanism includes that motor 7, motor 7 outfan are provided with rotating shaft 8, and rotating shaft 8 end is connected with gear 9, and gear 9 is placed in the gear grooved 10 that slide plate 3 end is offered, and gear 9 is wanted to engage with described rack rails 2.

In order to improve intensity and the structural stability of framework 1, being provided with reinforcing plate 12 in the middle part of described framework 1, reinforcing plate 12 direction is perpendicular with slide bar 4.

In order to anti-limited slip plate 3 offsets, described slide bar 4 at least two.

During use, hanger (not shown) is connected with the steel wire rope on lifting machine, the length adjusting steel wire rope ensures that framework 1 is in level or the state close to level, then framework 1 is placed on and needs above the steelframe of lifting, the all motors 7 started on slide plate 3 together rotate, motor 7 is rotated by rotating shaft 8 driven gear 9, owing to gear 9 is intended to the rack rails 2 on framework 1 to engage, rotation along with gear 9, the slip of slide plate 3 can be realized, slide plate 3 slide through slide 5 and slide bar 4 realizes, the movement of framework 1 is stopped with steelframe edge Hoisting Position after flushing bottom claw 11, motor 7 is braked and is rotated backward, slide plate 3 is driven mutually to draw close, during drawing close, claw 11 catches on steelframe edge and i.e. completes the card of steelframe and fasten, can lift.
