Abstract

A synchronous telescopic bracket comprises a bracket body, wherein a rotating shaft is arranged on the axis of the bracket body, and stretching ropes and retracting ropes are wound on the rotating shaft. A first telescopic bracket body and a second telescopic bracket body with bending sections are symmetrically arranged on two sides of the bracket body. A pulley is respectively arranged at each of two ends of the bracket body. The first stretching rope is fixed on the end portion of the first telescopic bracket body located in the bracket body after the first stretching rope passes through a first fixed pulley, one end of the second stretching rope is fixed on the first telescopic bracket body, and the other end of the second stretching rope is fixed on the second telescopic bracket body. The retracting ropes include a first retracting rope and a second retracting rope, the first retracting rope is fixed on the second telescopic bracket body after passing through a second fixed pulley, and the second retracting rope is connected between the first telescopic bracket body and the second telescopic bracket body. The synchronous telescopic bracket is simple in structure, ingenious in design and capable of changing the effective loading area according to practical requirements.

Description

But the carriage of synchronization telescope

Technical field

The utility model relates to a kind of carriage, but a kind of carriage of synchronization telescope particularly.

Background technology

In the manufacture process of ship superstructure, need to use the large-scale interim parked steel structure support of using with fitting-out.Its length of traditional steel structure support (carriage) generally all about 10 meters, is regular length.But because the size of superstructure is often huger, its width generally about 30 meters, therefore just needs configuration two cover carriages on Width, then need two covers or three cover carriages on the length direction, so altogether just needs 4 to 6 cover carriages.So many carriage can affect the space of occupied ground on the shelf, but also has improved the cost of making carriage.Therefore need now a kind of carriage that can address the above problem.

Summary of the invention

The utility model is in order to solve the existing above-mentioned deficiency of prior art, propose a kind of simple in structure, design ingenious, but can change according to actual needs the carriage of the synchronization telescope of effective bearing area.

Technical solution of the present utility model is: but a kind of carriage of synchronization telescope, comprise protrusions 1, it is characterized in that: be provided with rotating shaft 2 on the geometric central axis line of described protrusions 1, be wound with stretching rope 3 and reclaim rope 4 in rotating shaft 2, the bilateral symmetry of protrusions 1 be provided with the first telescoping bracket body 5 that the cross section is bending-type, the second telescoping bracket body 6, and the part of these two telescoping bracket bodies is plugged in the protrusions 1 and can moves with respect to protrusions 1, be respectively arranged with the first fixed pulley 7 and the second fixed pulley 8 at the two ends of protrusions 1, stretching rope 3 is divided into the first stretching rope 9 and the second stretching rope 10, wherein the first stretching rope 9 is by behind the first fixed pulley 7, being fixed on the first telescoping bracket body 5 is positioned on the end portion of protrusions 1, one end of the second stretching rope 10 is fixed on the first telescoping bracket body 5, and the other end is fixed on the second telescoping bracket body 6 after by the second fixed pulley 8 and is positioned on the end portion of protrusions 1; Reclaim rope 4 and be divided into the first recovery rope 11 and the second recovery rope 12, first reclaims rope 11 by behind the second fixed pulley 8, be fixed on the second telescoping bracket body 6 and be positioned on the end portion of protrusions 1, between the first telescoping bracket body 5 and the second telescoping bracket body 6, connect second and reclaim rope 12.

The utility model is compared with prior art, has following advantage:

But the carriage of the synchronization telescope of this kind of version, it is simple in structure, design ingenious, rationally distributed, it is for the existing intrinsic problem of existing steel structure support (carriage): loaded area is relatively fixing, during such as the larger superstructure of needs carrying volume, then be merely able to correspondingly increase the quantity of steel structure support, do so not only and can improve productive costs, and when temporarily not needing to use these carriages, also can take a large amount of working spaces.Design dexterously and can just can change the carriage effective bearing area by simple operations, and when not using, can also reduce the special construction of its floor area, and the manufacture craft of this carriage is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market outlook are very wide.

Fig. 2 is the schematic diagram of the utility model embodiment recovering mechanism.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.Such as Fig. 1, shown in Figure 2: but a kind of carriage of synchronization telescope, comprise one as the protrusions 1 on basis, geometric central axis line at protrusions 1 is provided with rotating shaft 2, be wound with stretching rope 3 and reclaim rope 4 in rotating shaft 2, the bilateral symmetry of protrusions 1 be provided with two the first telescoping bracket bodies 5 and the second telescoping bracket body 6, and the cross section of the two is the bending-type of L shape, be respectively arranged with the first fixed pulley 7 and the second fixed pulley 8 at the two ends of protrusions 1, stretching rope 3 is divided into the

first stretching rope

9 and 10 two parts of the second stretching rope, wherein an end of the first stretching rope 9 is the end that stretches, after the other end is walked around rotating shaft 2, being fixed on the first telescoping bracket body 5 by the first fixed pulley 7 is positioned on the end portion of protrusions 1, and an end of the second stretching rope 10 is fixed on the first stretching protrusions 5, and the other end is fixed on the second telescoping bracket body 6 after by the second fixed pulley 8 and is positioned on the end portion of protrusions 1;

Reclaim rope 4 and also be divided into the first recovery rope 11 and the second recovery rope 12 two parts, wherein first end that reclaims rope 11 is recovery end, the other end is by behind the second fixed pulley 8, be fixed on the second rope protrusions 6 and be positioned on the end portion of protrusions 1, between the first telescoping bracket body 5 and the second telescoping bracket body 6, be connected with second and reclaim rope 12.

But the working process of the carriage of the synchronization telescope of the utility model embodiment is as follows: when the small product size that need carry when carriage is larger, utilize crane to pull the free end (i.e. the first stretching rope 9) of stretching rope 3, after the first stretching rope 9 changes direction by the first fixed pulley 7, hauling the first telescoping bracket body 5 outwards moves, after the other end that is connected to simultaneously the second stretching rope 10 on the first telescoping bracket body 5 changes directions by the second fixed pulley 8, hauling the second telescoping bracket body 6 outwards moves, namely by pulling stretching rope 3, realize the first telescoping bracket body 5 and the second telescoping bracket body 6 simultaneously, the purpose of outwards moving synchronously; After two telescoping bracket bodies move to outer end position, stop action, crane is removed, jointly form a carriage that area is larger by protrusions 1 and two telescoping bracket bodies.

After carriage is finished using, utilize crane to pull the free end (namely first reclaiming rope 11) of recovery rope 4, the first recovery rope 9 directly hauls the second telescoping bracket 6 and inwardly moves, after being connected to second on the second telescoping bracket 6 and reclaiming rope 12 and change directions by the second fixed pulley 8, spurring the first telescoping bracket 5 inwardly moves, namely reclaim rope 4 by pulling, realize the first

telescoping bracket body

5 and 6 whiles of the second telescoping bracket body, the synchronous inwardly purpose of motion; After two telescoping bracket bodies move to inner end position, stop action, crane is removed, carriage is in the volume minimum rating, reduces as far as possible the occupation of land space of carriage.
