Description

Technical Field

[0001] This utility model relates to the field of corridor trolley technology, and in particular to a formwork moving trolley applied to small cross-section corridors. Background Technology

[0002] The construction of corridors typically involves the installation of corridor formwork. Traditional corridor formwork construction usually employs a full-span scaffolding support system; however, this method suffers from low construction efficiency.

[0003] In related technologies, in order to improve construction efficiency, some construction processes for large-section corridors adopt movable hydraulic support systems. However, this cannot meet the spatial requirements for the construction of small-section corridors, that is, the support system for large-section corridors cannot be applied to small-section corridors.

[0004] Therefore, there is an urgent need for a formwork transfer trolley for small-section corridors to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a formwork transfer trolley for small-section corridors, which can improve the construction efficiency of small-section corridors while meeting space requirements.

[0006] This utility model embodiment provides a formwork transfer trolley for use in small-section corridors, including:

[0007] The base has a walking device and a braking device at the bottom, and a support system at the top;

[0008] The template system is connected to the support system. When the support system fully supports the template system, the support system has a star-shaped structure.

[0009] The lifting device includes a first lead screw and a turbine assembly rotatably connected to the first lead screw. The bottom end of the first lead screw is fixed to the base by a flange. The first lead screw can rotate relative to the flange. One end of the turbine assembly is fixed to the support system. By rotating the turbine assembly, the turbine assembly drives the support system to move up and down along the axial direction of the first lead screw.

[0010] Preferably, the small-section corridor includes a water conveyance corridor, a power transmission corridor, and a drainage corridor.

[0011] Preferably, the walking device includes rollers, and a track is provided below the rollers, so that the rollers can travel along the track.

[0012] Preferably, the braking device includes a brake seat and a threaded rod threadedly connected to the brake seat. A push rod is provided on the threaded rod. By rotating the push rod, the threaded rod can move up and down relative to the brake seat, and the top of the threaded rod can abut against the bottom surface of the base.

[0013] Preferably, the template system includes a side template and a top template, which are connected by a second lead screw to adjust the distance between them.

[0014] Preferably, the support system includes a vertically arranged support frame, two second support rods, and two third support rods. The top end of the support frame is connected to the top edge template, and the support frame is connected to the turbine assembly. The support frame can move up and down relative to the base. One end of each of the second and third support rods is hinged to the side template, and the other end is hinged to the support frame. When the support system fully supports the template system, the two second support rods are horizontally arranged, and the two third support rods are inclined, with the third support rods positioned below the second support rods.

[0015] As can be seen from the above solution, the formwork trolley for small-section corridors provided by this utility model replaces the hydraulic support system used in the construction process of large-section corridors by setting up a lifting device composed of a first lead screw and a turbine assembly rotatably connected to the first lead screw, thereby reducing the space requirements of the cross-section. By setting a traveling device and a braking device under the base, the formwork trolley can travel and brake, thus improving the construction efficiency of small-section corridors while meeting space requirements. In addition, when the support system fully supports the formwork system, the support system has a star-shaped structure, which can effectively ensure the stable support of the support system for the formwork system.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] Please see Figure 1 One embodiment of this utility model provides a formwork transfer trolley for use in small-section corridors, comprising:

[0041] The base 1 has a walking device 2 and a braking device 3 below it, and a support system 4 above it;

[0042] The template system 5 is connected to the support system 4. When the support system 4 fully supports the template system 5, the support system 4 has a star-shaped structure.

[0043] The lifting device 6 includes a first lead screw 61 and a turbine assembly 62 rotatably connected to the first lead screw 61. The bottom end of the first lead screw 61 is fixed to the base 1 by a flange 63. The first lead screw 61 can rotate relative to the flange 63. One end of the turbine assembly 62 is fixed to the support system 4. By rotating the turbine assembly 62, the turbine assembly 62 drives the support system 4 to move up and down along the axial direction of the first lead screw 61.

[0044] In this embodiment, a lifting device 6, consisting of a first lead screw 61 and a turbine assembly 62 rotatably connected to the first lead screw 61, is used to replace the hydraulic support system used in the construction process of large-section corridors, thereby reducing the space requirements of the cross-section. By setting a traveling device 2 and a braking device 3 below the base 1, the traveling and braking of the formwork trolley can be realized, thus improving the construction efficiency of small-section corridors while meeting space requirements. In addition, when the support system 4 fully supports the formwork system 5, the support system 4 has a star-shaped structure, which can effectively ensure the stable support of the support system 4 for the formwork system 5.

[0045] It is understandable that the lifting device 6 employs the basic principle of a worm gear mechanism, also known as a screw jack in engineering. Screw jacks typically use a rotating turbine to drive a screw in axial motion. However, in this application, by restricting the axial movement of the screw (i.e., the first screw 61) to only circular motion, the turbine can move along the screw's axis when it rotates. Therefore, by fixing the turbine assembly 62 and the support system 4, the vertical movement of the support system 4 can be achieved.

[0046] In one embodiment of this utility model, the small-section corridor includes a water conveyance corridor, an electric power corridor, and a drainage corridor.

[0047] In one embodiment of the present invention, the walking device 2 includes a roller 21, and a track 22 is provided below the roller 21, so that the roller 21 can walk along the track 22.

[0048] In one embodiment of the present invention, the braking device 3 includes a brake seat 31 and a threaded rod 32 threadedly connected to the brake seat 31. A push rod 33 is provided on the threaded rod 32. By rotating the push rod 33, the threaded rod 32 can move up and down relative to the brake seat 31, and the top of the threaded rod 32 can abut against the bottom surface of the base 1.

[0049] It is understandable that when the roller 21 rolls on the track 22, the braking device 3 may not be placed under the base 1; when the formwork trolley arrives at the construction section, the braking device 3 is placed under the base 1, and the threaded rod 32 is moved upward relative to the brake seat 31 by rotating the push rod 33, so that the top of the threaded rod 32 abuts against the bottom surface of the base 1, thereby braking the formwork trolley; after the pouring is completed, the threaded rod 32 is moved downward relative to the brake seat 31 by rotating the push rod 33, so that the top of the threaded rod 32 disengages from the bottom surface of the base 1, thereby releasing the brake on the formwork trolley.

[0050] In one embodiment of the present invention, the template system 5 includes a side template 51 and a top template 52, which are connected by a second lead screw 53 to adjust the distance between the side template 51 and the top template 52.

[0051] In this embodiment, by setting the second lead screw 53, it is beneficial to realize the construction and demolding of the template system 5.

[0052] In one embodiment of this utility model, the support system 4 includes a support frame 41 arranged vertically, two second support rods 42 and two third support rods 43. The top end of the support frame 41 is connected to the top edge template 52. The support frame 41 is connected to the turbine assembly 62. The support frame 41 can move up and down relative to the base 1. One end of each of the second support rods 42 and the third support rods 43 is hinged to the side template 51, and the other end is hinged to the support frame 41. When the support system 4 fully supports the template system 5, the two second support rods 42 are arranged horizontally, and the two third support rods 43 are arranged at an angle. The third support rods 43 are arranged below the second support rods 42.

[0053] It is understandable that the support frame 41 can be provided with protrusions (or grooves), and the base 1 can be provided with corresponding grooves (or protrusions) to achieve the concave-convex fit between the support frame 41 and the base 1, which facilitates the lifting device 6 to lift the support frame 41.

[0054] In some embodiments, the lengths of the second support frame 42 and the third support frame 43 are adjustable. The adjustable length can be achieved by a cylinder or a lead screw, which will not be described in detail here.

[0055] It should be noted that in this invention, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is used only to illustrate the technical solution of this utility model, and is not intended to limit the protection scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the protection scope of this utility model.
