However, the structure of the retractable roof is still under the research stage in China at present, and the retractable roof may have the problems of equipment failure, operation stop and the like in the use process.

The retractable roof structure can be divided into: horizontal movement, horizontal rotation, spatial movement, pivoting, etc., typically consist of a movable roof, a fixed roof, and a drive control system. The driving system commonly used for the horizontal retractable roof structure comprises a wheel type driving system, a rack and gear system, a steel wire rope traction system and a chain and chain driving system. In the first two driving modes, the driving trolley transmits driving force to the movable roof, and simultaneously transmits the load of the movable roof to the lower structure, at present, the movable roof is connected with the top of the driving trolley by using a flange plate and a high-strength bolt, but the connecting mode has higher requirements on the strength and the rigidity of the trolley track, and the requirement that the track is hardly deformed in the operation process of the driving trolley is met. However, in practical engineering, the trolley rails are often subjected to inevitable geometric deformation due to factors such as structural stress, installation errors and the like, and the deformation of the rails is different along with the structural form and span. The prior art can not meet the requirement that the trolley still can normally run under the condition that the track is greatly deformed, and then the phenomenon that the trolley is separated from the track and slips occurs, so that the driving system is failed.

Detailed Description

The invention will now be further described with reference to the accompanying drawings.

The design principle of the invention is that the driving system can be adjusted in time according to the unevenness and deformation of the track, so that the driving system can adapt to the deformation of the track in the vertical direction, the driving trolley is always attached to the track in the running process of the retractable roof, and the safety and the high efficiency of the retractable roof in the use process are further ensured.

Example 1

Referring to fig. 1 to 3, the present invention provides a spring bracket for driving a dolly, comprising:

an upper transmission plate 2, the upper surface of which is intended to be welded to the superstructure 1; the upper edge of the upper part is provided with a sliding slot hole 21 along the longitudinal direction, and the upper transmission plate 2 adopts a square plate in the embodiment, but the shape is not limited;

the bottom surfaces of the two lower transmission plates 3 are respectively welded with the driving trolley 5, the two lower transmission plates 3 are respectively attached to two side surfaces of the upper transmission plate 2, the opposite surfaces of the two lower transmission plates 3 are respectively provided with a sliding block part, and the two sliding block parts are respectively embedded in the corresponding sides in the sliding groove holes 21, so that the upper transmission plate 2 and the lower transmission plate 3 are connected in a vertical sliding mode, in the embodiment, the lower transmission plates 3 are isosceles trapezoids, but the shapes are not limited; the upper transmission plate 2 and the lower transmission plate 3 can ensure a certain movement space in the vertical direction, and are mutually attached in the left-right direction and the front-back direction;

and the spring adjusting device 4 is elastically deformed in the longitudinal direction to drive the upper transmission plate 2 to do corresponding up-and-down motion along the lower transmission plate 3. When the compression amount of the spring adjusting device 4 is changed, the relative displacement in the vertical direction between the upper transmission plate 2 and the lower transmission plate 3 can be allowed, the relative displacement in the left-right direction and the front-back direction can not be generated, and the driving trolley 5 can be ensured to normally run on the track 6 without departing from the track 6. In this case, the spring adjustment device 4 is arranged between the superstructure 1 and the drive trolley 5 and/or the spring adjustment device 4 is arranged at the groove bottom of the slotted-guide hole 21.

Two spring adjusting devices 4 are arranged between the upper structure 1 and the driving trolley 5 and are respectively positioned at two sides of the lower transmission plate 3; the spring device comprises an upper backing plate 41, a spiral spring 43 and a lower backing plate 45; the upper surface of the upper backing plate 41 is used for being fixed on the lower surface of the upper structure 1, the lower surface of the lower backing plate 45 is fixed on the driving trolley 5, the upper positioning block 42 is welded on the lower surface of the upper backing plate 41, the lower positioning block 44 is welded on the upper surface of the lower backing plate 45, and two ends of the spiral spring 43 are respectively sleeved on the upper positioning block 42 and the lower positioning block 44. And the lower backing plate 45 is assembled and connected with the upper top plate 51 of the driving trolley 5 by adopting a fastener, and the edge of at least one symmetrical side of the lower backing plate 45 is positioned outside the corresponding side of the outer contour of the plurality of spiral springs 43 and is used for arranging a fastener assembling hole 46. In this example, the fastening member is a bolt 47, and the tightening amount of the bolt 47 is determined according to the maximum vertical deformation which may occur in the track 6 where the driving trolley 5 is located in the actual engineering, so as to ensure that the coil spring 43 is in a compressed state after the installation is completed.

In this example, the number of the coil springs 43 is 4, and the coil springs are respectively arranged at four corners of the lower surface of the upper mat 41.

The working principle is as follows: during actual work, the driving force of the driving trolley 5 is transmitted to the upper structure 1 through the lower transmission plate 3 and the upper transmission plate 2 in sequence, so that the upper structure 1 moves; when the track 6 where the driving trolley 5 is located is deformed, the rigidity of the upper structure 1 is high, the deformation of the upper structure 1 is small, the driving trolley 5 is separated from the track 6, a slipping phenomenon occurs, the compression amount of the spiral spring 43 is reduced by the spring adjusting device 4, so that the upper transmission plate 2 and the lower transmission plate 3 are displaced relative to each other in the vertical direction, and the driving trolley 5 continues to run on the track 6.

Further, in this embodiment, a linear spring may be provided on the bottom surface of the slide groove hole 21, and the top of the linear spring may contact the bottom surface of the slide portion.
