Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices for civil engineering construction, and specifically, to a guide wheel assembly for transferring long strip precast components. Background Technique

[0002] In the field of civil engineering construction, in order to achieve the purpose of rapid construction, precast structures are usually adopted, including precast reinforced concrete structures (such as precast box girders, precast floor slabs, precast culverts, precast decorative masonry materials, etc.), precast steel structures (such as precast steel beams, precast steel plates, etc.), and temporary structures that are assembled on site and reused, etc.

[0003] In a construction project, there are usually various structures, which also leads to the consideration of setting all components that can be standardized produced as precast components and then transporting them to the construction site for installation. However, the sizes of precast components vary, with large ones such as 40m precast T-beams, small ones such as 2m precast culvert segments, and even 1m long strip curb stones all within the scope of precast.

[0004] For these precast components with different sizes and weights, the current construction situation is as follows:

[0005] ① The construction site is basically equipped with lifting equipment (such as gantry cranes, truss cranes) according to the largest model to meet the lifting requirements.

[0006] ② When within the lifting capacity range, no matter how large the object to be lifted is, try to choose a single lifting equipment (i.e., one unit). When the weight exceeds the limit, choose multiple equipment for combined lifting.

[0007] ③ The precast component can only be moved by the lifting equipment within the working range of the lifting equipment.

[0008] ④ There are usually only about 2 types of lifting machinery at the construction site, which is difficult to meet the requirements of appropriate resource allocation.

[0009] The main problems are as follows:

[0010] ① The lifting equipment usually has only one lifting point (such as gantry cranes, truss cranes, truck cranes, etc.). After the steel wire rope hangs the object, it is concentrated at one point on the hook, which will cause the lifted object to be unable to maintain balance and is extremely easy to flip in the air, resulting in dangerous accidents.

[0011] ② When lifting large precast components and two or more lifting equipment are required, the specifications, models, and usage conditions of each lifting equipment need to be the same, and it extremely tests the operator's level. Once the operation of each equipment is not synchronized, the force will be directly transmitted to the object to be lifted through the steel wire rope, causing its damage and even dropping.

[0012] ③ Usually, it is impossible to continue moving the position after the precast component lands, and it is difficult to make adjustments. Summary of the Utility Model

[0013] The present utility model is made to solve the above technical problems, and one of its purposes is to provide a guide wheel assembly for transferring long-strip precast components, which can be applicable to the transfer operations of precast components of different sizes and weights.

[0014] According to an embodiment of the present utility model, there is provided a guide wheel assembly for transferring long-strip precast components, including a bottom support with a first connecting member provided on the upper side and a second connecting member provided on the lower side; a tray with a first rotating shaft formed on the lower side and rotatably arranged in the first connecting member; a free wheel with a second rotating shaft formed on the upper end and rotatably arranged in the second connecting member.

[0015] As an embodiment, the first connecting member is of a cylindrical structure, and a circular groove capable of accommodating the first rotating shaft is formed inside; the second connecting member is of a cylindrical structure, and a circular groove capable of accommodating the second rotating shaft is formed inside.

[0016] As an embodiment, more than three of the first connecting members are evenly arranged on the lower side of the bottom support, and the free wheel is rotatably arranged on each of the first connecting members.

[0017] As an embodiment, four of the first connecting members are evenly arranged on the lower side of the bottom support.

[0018] As an embodiment, a traction hole is formed at one end of the bottom support.

[0019] As an embodiment, it further includes: a rotating joint, one end of which is rotatably connected in the traction hole along a first direction; a traction rod, one end of which is rotatably connected to the other end of the rotating joint along a second direction; wherein the first direction is the horizontal direction and the second direction is the vertical direction, or the first direction is the vertical direction and the second direction is the horizontal direction.

[0020] As an embodiment, an anti-slip pad is provided on the upper surface of the tray or an anti-slip surface is formed.

[0021] As an embodiment, the free wheel includes a main body structure and rollers provided on both sides thereof, and the second rotating shaft is fixedly provided at the upper end of the main body structure.

[0022] According to the above description and practice, the guide wheel assembly for transferring long-strip precast components of the present utility model has the following advantages:

[0023] 1. The guide wheel assembly for transferring long-strip precast components can be used alone or in combination according to requirements, and can be applicable to precast components of different sizes and weights, form stable support for them, and carry out transfer operations.

[0024] 2. In the guide wheel assembly for transferring the long strip-shaped precast components, the object tray, the bottom support, and the free wheels adopt a detachable connection method, which facilitates their assembly and disassembly. After some components are damaged, they can be replaced, saving costs. It is convenient to carry during use and has strong applicability.

[0025] 3. Based on the rotational degrees of freedom of the free wheels and the object tray relative to the bottom support, the guide wheel assembly can achieve horizontal free rotation to meet the transfer requirements in different directions.

[0026] 4. When the guide wheel assembly for transferring the long strip-shaped precast components is in use, for precast components with relatively small weights, it can be pulled or pushed by hand, and the transfer of the precast components can be completed by manpower, with even stronger applicability.

[0027] 5. It reduces the requirements for lifting equipment and lifting personnel during the transfer of precast components, reduces the risk, and the entire process is operated on the ground surface, making it not easy to cause damage to the precast components. In addition, compared with multiple people controlling multiple lifting equipment, it reduces the manpower consumption, saves the labor cost and expenditure, and also saves the use cost of construction machinery.

[0028] 6. The guide wheel assembly for transferring the long strip-shaped precast components is easy to use, safe and efficient, and significantly improves the construction efficiency and safety. Brief Description of the Drawings

[0047] Embodiment 1

[0048] In this embodiment, a guide wheel assembly for transferring long-strip precast components is provided. As shown in Figure 1a and Figure 1b , the guide wheel assembly includes a bottom support 1, an object-carrying tray 2, and a free wheel 3. The bottom support 1 is located in the middle, with a free wheel 3 provided on its lower side and an object-carrying tray 2 provided on its upper side. The object-carrying tray 2 contacts the precast component to be transferred to support the precast component, and then the free wheel 3 can be used to transfer the precast component.

[0049] Please refer to Figures 3a to 5 . The main body of the bottom support 1 is a plate-shaped component. A first connecting member 11 is provided on the upper side of the bottom support 1 for connecting with the object-carrying tray 2, and a second connecting member 12 is provided on the lower side of the bottom support 1 for connecting with the free wheel 3. The main body of the object-carrying tray 2 is a plate-shaped component, and its upper end face is a supporting surface that contacts the precast component to be transferred. A first rotating shaft 21 that is rotatably arranged in the first connecting member 11 is formed on the lower side of the object-carrying tray 2. After the object-carrying tray 2 and the bottom support 1 are connected together through the first connecting member 11 and the first rotating shaft 21, the object-carrying tray 2 can rotate axially around the first rotating shaft 21, and its radial displacement is restricted by the first connecting member 11. A second rotating shaft 31 that is rotatably arranged in the second connecting member 12 is formed at the upper end of the free wheel 3. After the free wheel 3 and the bottom support 1 are connected together through the second connecting member 12 and the second rotating shaft 31, the main body of the free wheel 3 can rotate axially around the second rotating shaft 31, and its radial displacement is restricted by the second connecting member 12.

[0050] The guide wheel assembly for transferring long-strip precast components can be applicable to the transfer operations of precast components with different sizes and weights. As shown in Figure 2 , for precast components with relatively large volumes, four such guide wheel assemblies for transferring long-strip precast components can be used and placed in the four corner areas below the precast component respectively to form support for the precast component. Subsequently, the precast component can be pushed or pulled to transfer it. For precast components with other sizes and weights, the number of the guide wheel assemblies can be appropriately increased or decreased, and the transfer operation can also be carried out in the above manner.

[0051] As an embodiment, the first connecting member 11 is in a cylindrical structure, and a circular groove for accommodating the first rotating shaft 21 is formed inside it. The first rotating shaft 21 is inserted into the first connecting member 11; the second connecting member 12 is in a cylindrical structure, and a circular groove for accommodating the second rotating shaft 31 is formed inside it. The second rotating shaft 22 is inserted into the second connecting member 12. This structural form can not only stably realize the rotational connection between the bottom tray 1, the object tray 2 and the free wheels 3, but also the bottom tray 1, the object tray 2 and the free wheels 3 adopt a plug-in connection method, which is convenient for assembly and disassembly. After some components are damaged, they can be replaced, saving costs, being convenient to carry during use and having strong applicability.

[0052] As an embodiment, more than three first connecting members 11 are evenly arranged on the lower side of the bottom tray 1, and a free wheel 3 is rotatably arranged on each first connecting member 11. When the precast member to be transferred is small, setting one such guide wheel assembly below it can realize the transfer operation, and more than three free wheels 3 can ensure that the guide wheel assembly is not prone to tipping during use. For example, in this embodiment, four first connecting members 11 are evenly arranged on the lower side of the bottom tray 1. Figure 5 The four free wheels 3 shown in the figure are installed in the corresponding first connecting members 11, and can transfer the precast member more stably.

[0053] Furthermore, as Figure 5 shown, in this embodiment, the free wheel 3 includes a main body structure 32 and rollers 33 arranged on both sides of it, and the second rotating shaft 31 is fixedly arranged at the upper end of the main body structure 32. As an embodiment, the second rotating shaft 31 and the main body structure 32 can be an integral structure, which can have strong supporting ability. For example, by adopting the process of casting and integrally forming, the free wheel 3 can be made at a lower cost. This structural form of the free wheel 3 can be applied to the transfer operation of precast members with larger weights. For precast members with smaller weights, the free wheel 3 can also be selected as a common universal wheel on the market, and the transfer operation of precast members can also be realized at a lower cost.

[0054] As an embodiment, an anti-slip pad is provided on the upper surface of the object tray 2 or an anti-slip surface is formed, which can make the precast member to be transferred contact the object tray 2 more closely and firmly, and prevent the precast member from slipping off the object tray 2 during the transfer operation.

[0055] As an embodiment, a towing hole 13 is formed at one end of the bottom tray 1. It is convenient for users to connect the guide wheel assembly with a power device through a connecting member such as a rod or a rope, and can further improve the efficiency of transporting precast members. For example, during the transfer operation, the guide wheel assembly is connected with a tractor through a rope. At this time, the traction force is applied to the guide wheel assembly rather than the precast member. On the one hand, it can avoid damaging the precast member, and on the other hand, it can also be applied to the transfer operation of precast members with larger weights.

[0056] Embodiment 2

[0057] In this embodiment, another guide wheel assembly for transferring long strip-shaped precast components is provided. As Figures 6 to 8 shown, the guide wheel assembly includes a bottom support 1, an object support tray 2 and a free wheel 3. The bottom support 1 is located in the middle, with a free wheel 3 provided on its lower side and an object support tray 2 provided on its upper side. The object support tray 2 contacts the precast component to be transferred to support the precast component, and then the free wheel 3 can be used to transfer the precast component.

[0058] The main difference between the guide wheel assembly for transferring long strip-shaped precast components in this embodiment and the guide wheel assembly in Embodiment 1 is that a rotating joint 4 and a traction rod 5 are added. As Figure 6 and Figure 8 shown, one end of the rotating joint 4 is provided with a through hole opposite to the traction hole 13 and is rotatably connected to the traction hole 13 through a connecting shaft, so that the rotating joint 4 can rotate around the first direction and around the axial direction of the connecting shaft. The other end of the rotating joint 4 is rotatably connected to one end of the traction rod 5, and the two can rotate relative to each other along the second direction.

[0059] In this embodiment, the first direction is the vertical direction and the second direction is the horizontal direction. When performing the transfer operation of the precast component, the traction rod 5 can swing left and right and up and down, which is convenient for the operator to operate and also facilitates changing the transfer path. In other embodiments, the first direction can also be set as the horizontal direction and the second direction can be set as the numerical direction, and the above technical effects can also be achieved.

[0060] When using this guide wheel assembly for transferring long strip-shaped precast components to perform the transfer operation, the operator only needs to pull or push one end of the traction rod 5 to drive the precast component on the object support tray 2 to move, and the precast component can be transferred more conveniently and is not easily damaged. It is particularly suitable for precast components with a small weight and can quickly complete the transfer operation.

[0061] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
