Abstract
The utility model discloses a no bracing truss anti -swing puts structure installs on the truss of staircase, the truss is including the segmentation department crossbeam and the non - segmentation department crossbeam that have many crossbeams, anti -swing pendulum structure is the appearance design of Z type, including channel -section steel and rectangular pipe, the channel -section steel install in between the crossbeam of segmentation department crossbeam, the rectangular pipe install in between the crossbeam of non - segmentation department crossbeam the tip of the crossbeam of segmentation department crossbeam is equipped with connector plates, it is fixed through connector plates bolted connection between channel -section steel and the crossbeam. This kind of no bracing truss anti -swing puts structure adopts and set up channel -section steel and rectangular pipe on escalator truss's crossbeam, therefore has strengthened big lifting height escalator truss's intensity and steadiness in the great degree, avoids escalator truss to take place to sway and more serious incident, and is whole simple moreover, preparation simple to operate.
Description
technical field:
The utility model relate to a kind of large height staircase without the anti-swinging structure of sub-truss.
background technology:
Escalator is made up of the handrail of terraced road and both sides, its major part has step, conduction chain and sprocket wheel, guide track system, main transmission drive shaft, ladder road tightening device, handrail system, pecten, staircase skeleton and electric system etc., step forms ladder gradually after passenger entrance place moves horizontally, fade away close to entrance ladder, step moves horizontally once again, these motions are all by step main wheel, jockey pulley realizes along the walking of different step roller tracks respectively, the core component of escalator is two chains, they carry out cycle rotation around two pairs of gears, at staircase top, there is a direct motor drive transmission gear, to rotate chain ring, driving engine and chain system are all arranged in truss, staircase and girder is again main support and the load bearing component of staircase, and be a kind of staircase and girder type of large height without sub-truss, at megastore or station etc., this type staircase all can be used in multiple place at present, if but there is no midfoot support, can cause staircase steadiness and intensity poor, thus staircase entirety is caused to wave, may safety misadventure be there is in serious.
summary of the invention:
The technical problems to be solved in the utility model be to provide a kind of structure simple, install easy to make and effectively can strengthen the anti-swinging structure of truss of staircase bulk strength and steadiness.
For solving the problem, the utility model is achieved through the following technical solutions:
A kind of without the anti-swinging structure of sub-truss, be installed on the truss of staircase, described truss comprises the segmentation place crossbeam and non-segmentation place crossbeam with many crossbeams, the Z-shaped appearance design of described anti-swinging structure, comprise channel-section steel and rectangular tube, described channel-section steel is installed between the crossbeam of described segmentation place crossbeam, described rectangular tube is installed between the crossbeam of described non-segmentation place crossbeam, be provided with junction steel plate in the end of the crossbeam of described segmentation place crossbeam, be connected and fixed by junction steel plate bolt between described channel-section steel and crossbeam.
As preferably, the junction steel plate on the crossbeam of described segmentation place crossbeam shifts to install.
As preferably, be welded and fixed between described junction steel plate and beam-end.
As preferably, length and width, the thickness of described junction steel plate are respectively 200mm, 200mm, 15mm.
As preferably, described channel-section steel is 12# channel-section steel.
As preferably, the length and width degree of the square-section of described rectangular tube is respectively 80mm, 80mm, and its thickness of pipe is 4mm.
Compared with prior art, usefulness of the present utility model is: this without the anti-swinging structure of sub-truss, adopt and channel-section steel and rectangular tube are set on the crossbeam of staircase and girder, thus largely on enhance intensity and the steadiness of large hoisting depth staircase and girder, staircase and girder is avoided to wave and more serious safety misadventure, and overall simple, fabrication and installation are convenient, are thus applicable to applying.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Fig. 1 is the Facad structure schematic diagram of the utility model when being installed on crossbeam;
In figure: 1, crossbeam 11, segmentation place crossbeam 12, non-segmentation place crossbeam 2, channel-section steel 3, rectangular tube 4, junction steel plate
detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
The utility model is a kind of without the anti-swinging structure of sub-truss, as shown in Figure 1, be installed on the truss of staircase, described truss comprises the segmentation place crossbeam 11 and non-segmentation place crossbeam 12 with many crossbeams 1, the Z-shaped appearance design of described anti-swinging structure, comprise channel-section steel 2 and rectangular tube 3, described channel-section steel 2 is installed between the crossbeam 1 of described segmentation place crossbeam 11, described rectangular tube 2 is installed between the crossbeam 1 of described non-segmentation place crossbeam 12, junction steel plate 4 is provided with in the end of the crossbeam 1 of described segmentation place crossbeam 11, preferably, for convenience of installing and strengthening the steadiness of structure, be welded and fixed between described junction steel plate 4 and crossbeam 1 end, be connected and fixed by junction steel plate 4 bolt between described channel-section steel 2 and crossbeam 1, thus more can strengthen the steadiness of described truss integral framework and be convenient to installation and the dismounting of channel-section steel 2, more convenient and quicker is installed, save artificial and improve installation effectiveness, junction steel plate 4 on the crossbeam 1 of described segmentation place crossbeam 11 shifts to install, thus Z-type appearance structure can be formed when described crossbeam 1 is connected with channel-section steel 2, more be conducive to the steadiness improving truss integral structure, in addition, preferably, the length of described junction steel plate 4, wide, thickness is respectively 200mm, 200mm, 15mm, described channel-section steel 2 is 12# channel-section steel, the length of the square-section of described rectangular tube 3, width is respectively 80mm, 80mm, its thickness of pipe is 4mm, thus by selecting channel-section steel 2 and the rectangular tube 3 of suitable dimension and profile, while the overall truss intensity of guarantee and steadiness, can also save and make material and cost, therefore, above-mentioned this without the anti-swinging structure of sub-truss, adopt and channel-section steel and rectangular tube are set on the crossbeam of staircase and girder, thus largely on enhance intensity and the steadiness of large hoisting depth staircase and girder, staircase and girder is avoided to wave and more serious safety misadventure, and overall simple, fabrication and installation are convenient, be applicable to penetration and promotion.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
