Technical Field

[0001] This utility model relates to the field of mold support wheel technology, and in particular to a support wheel for a steel truss floor deck mold. Background Technology

[0002] Steel truss floor decking is a type of unsupported profiled composite floor decking. It consists of steel bars as the top chord, bottom chord, and web members, connected by resistance spot welding to form a truss. To enable streamlined production of floor decking, the floor decking is usually placed on a mold table, and the processing of the floor decking is achieved by moving the mold table. The mold table support wheels are a device that enables the movement of the mold table.

[0003] In the prior art, such as the support wheel assembly with publication number CN107554758B, there is a wheel and a support device. The support device includes a wheel fork, a support member, and a telescopic cylinder assembly. The wheel fork includes a wheel connecting part and a wheel fork plate. The wheel is hinged to the wheel connecting part. When the telescopic cylinder assembly of the support wheel assembly of this application is subjected to a large downward load, the guide sleeve slides along the sleeve, and the support member moves downward until it contacts the ground, so that the force is applied to the support member, thereby avoiding the wheel being subjected to a large load for a long time and improving the service life of the wheel. However, when this support wheel assembly is used, it does not have a fixing structure for the wheel, which makes it impossible for the wheel to stop. Therefore, a support wheel for a steel truss floor deck formwork is proposed. Utility Model Content

[0004] In view of this, the present utility model aims to provide a support wheel for a steel truss floor deck formwork to solve or alleviate the technical problems existing in the prior art. By installing the first sliding frame and the second sliding frame, the first sliding block can be driven to slide, so that the first sliding block after sliding can fix and release the rotating wheel. Because the rotating wheel can be fixed, the support wheel can be quickly stopped.

[0005] The technical solution of this utility model embodiment is implemented as follows:

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1-4As shown, this utility model embodiment provides a support wheel for a steel truss floor deck formwork, including: a base 1, a sliding seat 2 slidably fitted on the base 1, a rotating wheel 3 rotatably fitted inside the sliding seat 2, a first sliding frame 4, a second sliding frame 5, and a first sliding block 6 slidably fitted inside the sliding seat 2, two deformation strips 7 corresponding to the first sliding frame 4 and the second sliding frame 5 fixedly installed on the first sliding block 6, a first spring 8 fixedly installed between the first sliding frame 4 and the sliding seat 2, a second spring 9 fixedly installed between the sliding seat 2 and the first sliding block 6, a threaded rod 10 rotatably fitted inside the base 1 and threadedly fitted to the sliding seat 2, a second sliding block 11 corresponding to the threaded rod 10 slidably fitted inside the base 1, and a third spring 12 fixedly installed between the second sliding block 11 and the base 1.

[0025] In this embodiment, specifically: four guide rods 13 for guiding the sliding seat 2 are fixedly installed on the bottom of the base 1, and four fixing holes for fixing the support wheel are opened on the bottom of the base 1. The installation of fixing holes facilitates fixing the support wheel.

[0026] In this embodiment, specifically: a limiting protrusion is provided on the rotating wheel 3, and a limiting recess is provided on the limiting protrusion. An insertion protrusion 601 corresponding to the limiting recess is provided on the first sliding block 6. The opening of the limiting recess facilitates the fixing of the first sliding block 6 to the rotating wheel 3.

[0027] In this embodiment, specifically: one end of each of the two deformation strips 7 is set with an inclined structure, one end of the second sliding frame 5 is slidably engaged with one end of the deformation strip 7, one end of the deformation strip 7 is fastened to one end of the first sliding frame 4, and the installation of the second sliding frame 5 facilitates the compression of the deformation strip 7 and facilitates the sliding of the first sliding block 6 after the deformation strip 7 is compressed.

[0028] In this embodiment, specifically: a first pressing part 401 is provided at one end of the first sliding frame 4, and a second pressing part 501 is provided at one end of the second sliding frame 5. The provision of the first pressing part 401 facilitates pressing the first sliding frame 4.

[0029] In this embodiment, specifically: the sliding seat 2 is provided with a guide protrusion 201 for guiding the first sliding block 6, the bottom of the threaded rod 10 is provided with multiple arc-shaped recesses, the second sliding block 11 is provided with multiple arc-shaped protrusions 1101 embedded in the multiple arc-shaped recesses, the third spring 12 is located inside the second sliding block 11, and the opening of the arc-shaped recesses facilitates the second sliding block 11 to limit and fix the threaded rod 10.

[0030] In operation, when the support wheel needs to fix and release the rotating wheel 3, the second sliding frame 5 is pressed first. After being pressed, the second sliding frame 5 slides, compressing the deformation strip 7. When the deformation strip 7 is compressed, it deforms, disengaging from the first sliding frame 4. The second spring 9 then pushes the first sliding block 6 and the deformation strip 7 to slide. The first sliding block 6 then contacts the rotating wheel 3, stopping its rotation. At this point, the rotating wheel 3 is able to stop rotating. After wheel 3 comes to a complete stop, when it is necessary to release the rotating wheel 3, press the first sliding frame 4. After the first sliding frame 4 is pressed, it compresses and slides the first spring 8. After sliding, the first sliding frame 4 engages with the deformation strip 7. Then, release the force pressing the first sliding frame 4. At this time, the first spring 8 pushes the first sliding frame 4, the deformation strip 7, and the first sliding block 6 to slide. After sliding, the first sliding block 6 disengages from the rotating wheel 3. At this time, the second spring 9 is compressed by the first sliding block 6. At this time, the rotating wheel 3 is released and can rotate.

[0031] When the height of the support wheel needs to be fine-tuned, press down on the second sliding block 11. The second sliding block 11 compresses the third spring 12, disengaging the second sliding block 11 from the threaded rod 10. Then, rotate the threaded rod 10. The rotation of the threaded rod 10 drives the sliding seat 2 and the rotating wheel 3 to rise and fall. At this point, the height of the support wheel is fine-tuned. After the rotating wheel 3 is fine-tuned, it contacts and supports the mold table. Then, release the force pressing the second sliding block 11. The second sliding block 11 then limits the threaded rod 10, making it difficult for the threaded rod 10 to rotate.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
