Detailed Description
To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
At the in-process of buildding of large-scale truss, owing to there are many regions to need to adopt the welded mode, after the welding owing to need wait for the cooling design, the event often needs to install scaffold frame or other steel bearing structure additional in the bottom of truss and fixes, no matter at bearing structure's installation or dismantlement process, all difficult effect to a plurality of positions play the synchronous stay, and in the uninstallation, also be difficult to unload simultaneously a plurality of positions, to foretell technical problem, the utility model provides a following solution:
referring to fig. 1-2, a truss step-by-step unloading apparatus includes: a bottom pallet 1; an extension upright rod 2 vertically fixed on the bottom supporting plate 1; a herringbone sliding frame 3 fixed on the extension upright rod 2 in a locking way; a sliding plate 4 movably connected to the herringbone sliding frame 3; the telescopic rods 5 are vertically fixed on the sliding plate 4, the telescopic rods 5 are provided with matching holes 51, and the top of each telescopic rod 5 is provided with a support plate 52; the connecting rod 6 vertically penetrates through all the matching holes 51, and the limiting sleeves 7 are locked at two ends of the connecting rod 6, and the limiting sleeves 7 are tightly attached to the outer side face of the telescopic rod 5.
When the double-layer sliding plate is used, the bottom supporting plate 1 and the extension upright stanchion 2 are fixedly installed, then the herringbone sliding frame 3 is installed, the herringbone sliding frame 3 is of a rail type structure and can limit and guide the sliding of the sliding plate 4, and the telescopic rod 5 is installed on the sliding plate 4, so that the position can be changed along with the sliding of the sliding plate 4, the height of the supporting plate 52 is changed, and the purposes of supporting and unloading at any time are achieved.
And, as long as let the gliding displacement of slide 4 on both sides the same, can let two support plates 52 reach the purpose of supporting simultaneously, uninstallation simultaneously, compare in current scaffold frame or welding support, the flexibility degree is higher, and the synchronism is stronger.
Wherein, connecting rod 6 plays the effect of linking up all telescopic links 5, is connected with restriction cover 7 on the connecting rod 6, and in this embodiment, the quantity of telescopic link 5 is four, has two on every slide 4, and two telescopic links 5 that are in both ends that are the outside just laminate with restriction cover 7, can restrict telescopic link 5 and make it can't extend outward again to protection slide 4 can not break away from with herringbone carriage 3, lets slide 4 can provide sufficient holding power.
In order to ensure that the matching of the sliding plate 4 and the herringbone sliding frame 3 is more unobstructed and smoother in sliding matching, the inclination angle of the herringbone sliding frame 3 is the same as that of the sliding plate 4, and the herringbone sliding frame and the sliding plate are better in synchronism in matching at the same inclination.
The sliding plate 4 slides by matching a linear motor with a track of the herringbone carriage 3, and the sliding mode of the linear motor matching with the track is a conventional means for those skilled in the art, and will not be described in detail here.
In order to further reduce the friction coefficient between the herringbone sliding frame 3 and the sliding plate 4 and avoid the influence of the force which is not resistant when the herringbone sliding frame 3 and the sliding plate 4 slide, a lubricant is arranged between the herringbone sliding frame 3 and the sliding plate 4, so that the two sliding plates 4 can not be obstructed when sliding, the requirement of synchronism can be met, and the linear motor is matched with the herringbone sliding frame 3 at the inner side and is not influenced by the lubricant.
In the matching process of the connecting rod 6 and the limiting sleeve 7, in order to enable the limiting sleeve 7 to play a binding effect on the telescopic rod 5, the limiting sleeve 7 does not slide on the connecting rod 6 without binding, so the connecting rod 6 is a threaded rod, the limiting sleeve 7 is a nut, the limiting sleeve 7 is in threaded connection with the connecting rod 6, and after the sliding plate 4 slides to a specified position, the limiting sleeve 7 rotates on the connecting rod 6 to enable the limiting sleeve 7 to be attached to and limit the telescopic rod 5 in order to fix the positions of the carrier plate 52 and the telescopic rod 5 at the moment, so that the limiting sleeve 7 does not act any more.
In this embodiment, the telescopic rod 5 no longer only plays a telescopic role, and the specific structure of the telescopic rod 5 is set as follows: the telescopic rod 5 further comprises a fixed part 53 vertically locked at the bottom of the carrier plate 52, and a movable part 54 movably connected to the inner side of the fixed part 53, wherein the movable part 54 is locked at the top of the sliding plate 4, due to the position relationship of the matching hole 51 on the fixed part 53, the fixed part 53 always moves on the straight line on the connecting rod 6, and does not move up and down, and the movable part 54 changes along with the position of the sliding plate 4, so that the change in length occurs, for example, when the sliding plate 4 moves to the bottom, the length of the movable part 54 extends to the longest, and when the sliding plate 4 moves to the top, the length of the movable part 54 is the shortest, and the change in height of the sliding plate 4 is adapted through the change in length of the movable part 54.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
