Abstract
The utility model provides a landing stage is with preceding landing leg reinforcing stull device, includes by two preceding landing legs, the cylinder body of every preceding landing leg internal fixation hydro-cylinder, and the piston end of hydro-cylinder stretches out downwards, and the upper portion of the preceding landing leg extension festival is fixed to this piston end, and every preceding landing leg extension festival downwardly extending, preceding landing leg extension festival lower tip fixed support portion, be equipped with between two preceding landing leg extension festival and strengthen the stull. Compared with the prior art, the utility model discloses install and strengthen the stull, it can only slide in preceding landing leg extension festival vertical direction, has restricted preceding landing leg extension festival lateral displacement for the landing stage can realize the deformation that the landing stage produced under vehicle load operating mode pressurized by the safety and stability construction, the utility model discloses simple structure, convenient operation, the usage is extensive, very easily promotes.
Description
Technical Field
The utility model belongs to the technical field of tunnel landing stage or bridge girder erection machine construction, concretely relates to novel stull is strengthened to preceding landing leg device.
Background
With the rapid development of infrastructure construction in China, the mechanization requirements of concrete construction of tunnels, bridges, highways and the like are higher and higher, the front support leg lengthening sections of the existing trestle on the market are not provided with cross braces at present, the front support legs deform under compression under the working condition of vehicle load, and the trestle is unstable in the past and influences normal construction.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that traditional landing stage front leg adds the length festival, does not add the stull under the vehicle load operating mode, and front leg pressurized produces and warp, and this past landing stage can unstability, influences normal construction in the long term, the utility model provides a novel stull is strengthened to front leg device.
The purpose of the utility model is realized with the following mode:
the utility model provides a stull device is strengthened with preceding landing leg to landing stage, includes by two preceding landing legs, the cylinder body of every preceding landing leg internal fixation hydro-cylinder, and the piston end of hydro-cylinder stretches out downwards, and the fixed front leg of this piston end adds the upper portion of extension festival, and every preceding landing leg adds extension festival downwardly extending, and preceding landing leg adds the lower tip fixed support portion of extension festival, is equipped with between two preceding landing leg extension festival and strengthens the stull, specifically is: the reinforcing cross brace comprises a cross brace, two ends of the cross brace are respectively fixed with a hollow upright post, each upright post is sleeved outside the front supporting leg lengthening section on one side of each upright post, and the upright posts and the front supporting leg lengthening sections form a sliding kinematic pair.
The front supporting leg is fixed with the piston end of the front supporting leg extension joint in a screw connection mode.
And welding the cross brace and the upright post, and welding the upper side surface and the lower side surface of the upright post, which are welded with the right-angle seam of the cross brace, with the reinforced rib.
Compared with the prior art, the utility model discloses install and strengthen the stull, it can only slide in preceding landing leg extension festival vertical direction, has restricted preceding landing leg extension festival lateral displacement for the landing stage can realize the deformation that the landing stage produced under vehicle load operating mode pressurized by the safety and stability construction, the utility model discloses simple structure, convenient operation, the usage is extensive, very easily promotes.

Detailed Description
As shown in fig. 1 to 2, the front leg reinforcing cross brace device for the trestle comprises two front legs 1, wherein a cylinder body of a cylinder is fixed in each front leg 1, a piston end of the cylinder extends downwards, the piston end is fixed at the upper part of a front leg extension section 2, each front leg extension section 2 extends downwards, and a supporting part is fixed at the lower end part of the front leg extension section 2.
Be equipped with between two preceding leg extension sections 2 and strengthen stull 3, specifically do: the reinforcing cross brace 3 comprises a cross brace 31, two ends of the cross brace 31 are both fixed with a hollow upright post 32, each upright post 32 is sleeved outside the front leg extension section 2 on one side, and the upright posts 32 and the front leg extension sections 2 form a sliding kinematic pair.
The front supporting leg 1 and the piston end of the front supporting leg extension joint 2 are fixed in a screwed connection mode.
The crossbrace 31 and the upright post 32 are welded, and the upper and lower side surfaces of the upright post 32 and the crossbrace 31 which are welded at right angle are welded with reinforced ribs 33.
The working principle is as follows:
when landing leg extension section 2 before needs use, will strengthen earlier 3 covers of stull, leg extension section 2 is fixed in the front on landing leg 1 before again, according to the operating mode situation, the length of the extension of two preceding leg extension sections 2 of adjustment, the level of working face is kept, this adjustment in-process, make 3 stable in suitable position of strengthening the stull, at this moment, because strengthen 3 and can only slide in 2 vertical directions of preceding landing leg extension section, 2 lateral displacement of preceding leg extension section have been restricted, make the landing stage can the safety and stability construction.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
