Description

Crawling operation table

The utility model relates to the operating desk that a kind of builing industry is used when building flooring.

Build in the operation at the flooring of construction work at present, the concrete that stirs is transported to pouring location by trolley on the bridge plate that flooring is laid after the lifting derrick is promoted to flooring.Trolley directly is poured over concrete on the floor template that ties reinforcing bar when building, carry out smooth operation then, in operating process because rolling of trolley wheel and trampling of operating personnel, cause the change of surfacing steel bar design attitude, cause the floor structure bearing capacity to reduce, cause serious harm for the flooring quality.

The purpose of this utility model is for solving above-mentioned problem of building in the flooring construction, and a kind of use pouring location supporting trolley and operating personnel and Crawling operation table that can the shift position is provided.

The utility model is achieved in that Crawling operation table is by skeleton, panel, climbing mechanism and control stick are formed, panel is fixed on the skeleton, the skeleton both sides be equipped with respectively 2 groups mutually corresponding on, lower guideway, between the lower guideway climbing mechanism is housed on every group, have a pair of extensible on the climbing mechanism, the telescopic leg of shrinking and make telescopic leg return back to the resetting means of contraction state from extended configuration, and be provided with the upper roller that is used for the support platform skeleton and climbing mechanism is bearing in bottom roller on the lower guideway, place in order to the control stick of handling the climbing mechanism action between the two cover climbing mechanisms of each side of skeleton, and be hinged on the lower guideway.

Crawling operation table keeps the telescopic leg of two cover climbing mechanisms to be in extended configuration in use, and so as to the support operation platform, the telescopic leg of two cover climbing mechanisms is in contraction state in addition, makes the usefulness of traveling fully.Promotion by control stick, the climbing mechanism that is in contraction state is moved forward on the lower guideway of platform skeleton, make telescopic leg change extended configuration into then from contraction state, meanwhile, shrink by handling resetting means, make the telescopic leg that originally is in extended configuration, promote skeleton subsequently operating desk is pushed ahead, so cycling reaches the purpose of creeping forward.

Like this, transport to pouring location, just trolley is pushed to Crawling operation table when concrete.Dump concrete on platform, simultaneously, operating personnel carry out the smooth slotting work of smashing on platform.Smash one section, moved one section, whole flooring concreting work all can be carried out on Crawling operation table.Avoid rolling of trolley wheel and trampling of operating personnel, guaranteed that the flooring reinforcing bar constructs by design attitude, thereby guaranteed the pouring quality of flooring.

The course of work of this Crawling operation table is as follows: when Crawling operation table was in Fig. 1 state, in the climbing mechanism 3 of both sides, the climbing mechanism telescopic leg on every side left side was in extended configuration, and near the front end of platform skeleton 1.The right be in contraction state, and near the rear end of skeleton 1.Operating desk is by two groups of telescopic leg supportings on the left side, and two groups of climbing mechanisms that the right is in contraction state then are seated on the lower guideway 1.2 of platform.Move control stick 4, make its right shoulder 4.2 aim at the pushing ram bar ear 3.1.1 of the right climbing mechanism.Rotate the regulating shaft 4.3 on the control stick, the propelling pin 4.4 in the control stick is inserted in the pushing ram bar ear 3.1.1.Promote control stick subsequently forward.Under the drive of control stick 4, pushing ram 3.1 drives location case 3.4.1 together with foot rest 3.3 by propelling sleeve 3.1.3, and climbing mechanism 3 is pushed ahead along lower guideway 1.2.When arriving skeleton 1 front end, climbing mechanism stopped to move by resistance.Continue propulsive control bar 4 this moment, pushing ram continues reach by the thrust that propelling sleeve 3.1.3 overcomes location case 3.4.1 inner spring 3.4.3.The telescopic leg brace 3.2.1 that is hinged on pushing ram stretches downwards gradually, and the positioning piston 3.1.5 in propelling sleeve touches the locking hole 3.4.5 of case bottom, location, and till being pushed into spring 3.1.4 in the sleeve 3.1.3 and being pressed in the hole.At this moment, telescopic leg stretches and supports on floor template.Propelling sleeve 3.1.3 then is locked in the case 3.4.1 of location, and pushing ram and foot rest are in the relative fixed state.Meanwhile, the left side of control stick shoulder touches the reset switch 3.5.1 on the left side, thereby the slide plate 3.5.5 that resets is advanced to the locking hole 3.4.5 direction of location case 3.4.1, until the positioning piston 3.1.5 in the patchhole is ejected.The pressing plate 3.4.2 that resets that this moment, propelling sleeve 3.1.3 was positioned in the case immediately pushes back initial position, thereby makes pushing ram return initial position, and telescopic leg brace 3.2.1 is returned to horizontally-inclined position, and support foot is raised.At this moment four groups of climbing mechanisms all are in the front end of platform skeleton 1; And the keep left telescopic leg on limit of both sides transfers contraction state to by initial extended configuration, and the contraction state by initial on the limit of keeping right transfers extended configuration to.Promote control stick then backward, control stick is the axle center rotation with the propelling pin that inserts the right pushing ram bar ear 3.1.1 just, the hinge that is connected by control stick bottom and skeleton is pushed ahead skeleton, until the rear end of platform skeleton 1 to moving forward to foot rest 3.3, thereby cover a stroke.

If operating desk need move on, then the propelling pin 4.4 of control stick 4 is withdrawed from from the pushing ram bar ear 3.1.1 of the right climbing mechanism, then insert in the bar ear of left side climbing mechanism, repeat the aforesaid operations process, platform just can continue to creep forward.
