Description

Technical Field

[0001] This utility model belongs to the technical field of marine highway bridge construction equipment, specifically relating to an arc-shaped sliding plate base support structure for a displacement trolley. Background Technology

[0002] Mobile formwork construction is a highly efficient construction method for cast-in-place bridge box girders, and it has been widely used in bridge construction, becoming one of the core pieces of equipment in bridge construction. After a section of bridge construction is completed, the formwork is lowered onto a moving trolley, which supports the formwork and drives it longitudinally to the next construction position.

[0003] Therefore, a stable support structure needs to be designed on the moving trolley to provide stable sliding support for the moving formwork. Furthermore, during the longitudinal movement of the formwork, the pitch angle of the formwork needs to change with the height difference between the front and rear piers. Therefore, how to ensure stable sliding support for the formwork and adapt to the changes in the pitch angle of the formwork is a technical problem that needs to be solved. Utility Model Content

[0020] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0021] This utility model designs an arc-shaped sliding plate base support structure for a transfer trolley, which is used to provide sliding support for the mold frame during movement. For details, please refer to the appendix. Figure 1 -Appendix Figure 3The arc-shaped slide plate base support structure includes a slide 31 and a slide mounting base 32. The top surface of the slide 31 is flat, and the bottom surface of the slide 31 is arc-shaped. The slide 31 is installed in the slide mounting base 32. An arc-shaped support plate 321 is provided inside the slide mounting base 32. The arc-shaped bottom surface of the slide 31 is in surface contact with the arc-shaped support plate 321, so that the arc-shaped support plate 321 can provide sufficient support for the slide 31 (surface contact provides sufficient force-bearing surface). The slide 31 can also slide in an arc along the arc-shaped support plate 321, thereby adapting to the pitch angle change of the mold frame during movement (during operation, the mold frame rests on the slide 31).

[0022] The slide mounting base 32 is a rectangular box structure with an open top. At least two downward-protruding positioning posts 322 are provided on the bottom plate of the slide mounting base 32. Correspondingly, corresponding positioning holes are provided on the trolley body. The positioning posts 322 are embedded in the positioning holes to achieve positioning between the slide mounting base 32 and the trolley body. The slide mounting base 32 and the trolley body are then welded together for fixation. An arc-shaped elongated through hole 323 is provided on the side plate of the slide mounting base 32 as a sliding limit hole. A corresponding protruding post 311 is provided on the side wall of the slide 31. The protruding post 311 is inserted into the arc-shaped elongated through hole 323 to prevent the slide 31 from detaching from the slide mounting base 32.

[0023] Furthermore, multiple supporting ribs 324 are provided between the base plate of the slide mounting base 32 and the arc-shaped support plate 321 to strengthen the arc-shaped support plate 321.

[0024] Furthermore, since the mold frame rests on the slide 31 during operation and moves on the slide 31, multiple oil storage grooves 312 are provided on the upper surface of the slide 31 to store lubricating grease, thereby reducing the friction between the mold frame and the bottom surface.

[0025] Furthermore, multiple oil storage grooves can also be provided on the upper surface of the arc-shaped support plate 321 to store lubricating grease, thereby reducing the friction between the arc-shaped support plate 321 and the slide block 31.

[0026] See Appendix below. Figure 4 -Appendix Figure 6 This paper introduces how the arc-shaped skateboard base support structure of this utility model is applied to a transfer trolley.

[0027] The transfer trolley 100 includes a transfer trolley body 1. Lower hook units 2 are provided at the bottom of the longitudinal front and rear sides of the transfer trolley body 1 (longitudinal refers to the direction of the main longitudinal beam of the formwork). In use, the transfer trolley 100 is mounted on the pier-side support leg 200, and the lower hook units 2 of the transfer trolley 100 are hooked to the top flange of the pier-side support leg 200 (see Appendix). Figure 6A mold frame 300 is installed above the transfer trolley 100.

[0028] Two arc-shaped sliding plate base support structures 3 are provided on the main body 1 of the transfer trolley. These two arc-shaped sliding plate base support structures 3 are symmetrically arranged on the left and right sides of the transverse direction of the main body 1 of the transfer trolley. The arc-shaped sliding plate base support structures 3 are used to provide support for the mold frame (when the mold frame needs to be moved, the mold frame falls on the slide 31 of the arc-shaped sliding plate base support structure 3). The arc-shaped sliding plate base support structure 3 can also adapt to the pitch angle change of the mold frame and provide stable support for the mold frame.

[0029] In addition, guide rollers 4 are provided on the transfer trolley body 1. The number of guide rollers 4 is preferably four, with two guide rollers 4 arranged on the outer side of each arc-shaped slide base support structure 3. When it is necessary to move the mold frame, the mold frame descends onto the slide block 31 of the arc-shaped slide base support structure 3, and the guide rollers 4 are used to make rolling contact with the outer wall of the mold frame.

[0030] A connecting lug 11 is provided on the body 1 of the transfer trolley for connecting the longitudinal drive mechanism 5, which is used to drive the mold frame to move longitudinally. The longitudinal movement drive mechanism 5 includes a longitudinal movement drive cylinder 51 and a longitudinal movement connecting frame 52 connected to the front end of the longitudinal movement drive cylinder 51. The longitudinal movement connecting frame 52 is slidably mounted on the bottom rail of the mold frame, and positioning holes are evenly spaced along the length of the rail. The longitudinal movement connecting frame 52 is inserted into different positioning holes on the rail by a pin, thereby actuating the longitudinal movement drive cylinder 51 to drive the mold frame to move stepwise (when moving, first connect the longitudinal movement connecting frame 52 to the positioning hole on the bottom rail of the mold frame by a pin, then actuate the longitudinal movement drive cylinder 51 to achieve one step movement, then pull out the pin to reset the longitudinal movement drive cylinder 51, and after resetting, reconnect the longitudinal movement connecting frame 52 to the positioning hole on the bottom rail of the mold frame by a pin, and the longitudinal movement drive cylinder 51 actuates again to achieve the next step movement. The above operation is repeated to achieve stepwise movement of the mold frame by the longitudinal movement drive cylinder 51).

[0031] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0032] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0033] The present invention has been described above by way of example. It should be noted that, without departing from the core of the present invention, any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present invention.
