Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices for civil engineering construction, and specifically, to a mobile precast component transfer device. Background Art

[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 repeatedly used for on-site assembly.

[0003] In a construction project, there are usually various structures, which also leads to the fact that any components that can be produced standardized are considered to be set as precast components and then transported 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-shaped curb stones, all within the scope of precasting.

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

[0005] ① Generally, lifting equipment (such as gantry cranes, truss cranes) is configured at the construction site 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, a single lifting equipment (i.e., one unit) is preferably selected. When the weight exceeds the limit, multiple equipment are selected for combined lifting.

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

[0008] ④ There are usually only about two 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 make it impossible to maintain the balance of the lifted object and is extremely easy to flip in the air, causing 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 or 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 Invention

[0013] The present utility model is made to solve the above technical problems. One of its purposes is to provide a mobile precast component transfer device that 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 mobile precast component transfer device, including a support beam and two or more free wheel groups rotatably provided at the lower end thereof. Wherein, the free wheel group includes: a bottom bracket, the upper end of which is rotatably connected to the support beam; two or more free wheels, rotatably provided at the lower end of the bottom bracket.

[0015] As an embodiment, a shaft hole is provided at the lower end of the support beam; a first rotating shaft rotatably connected in the shaft hole is formed at the upper end of the bottom bracket, and a first connecting member is formed at the lower side thereof; a second rotating shaft rotatably provided in the first connecting member is formed at the upper end of the free wheel.

[0016] As an embodiment, the device includes two or more of the support beams, and a connecting beam is provided between adjacent support beams.

[0017] As an embodiment, a slot is formed on the side surface of the support beam, and a plug that can be inserted into the slot is formed at the side end of the connecting beam.

[0018] As an embodiment, the connecting beam includes a first beam body and a second beam body respectively arranged longitudinally and transversely.

[0019] As an embodiment, the first connecting member is of a cylindrical structure, and a circular groove for accommodating the second rotating shaft is formed inside.

[0020] As an embodiment, a towing hole is formed at one end of the bottom bracket.

[0021] As an embodiment, it further includes: a rotating joint, one end of which is rotatably connected in the towing hole along a first direction; a towing 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.

[0022] As an embodiment, an anti-slip pad is provided on the upper surface of the support beam or an anti-slip surface is formed.

[0023] As an embodiment, four of the free wheels are rotatably provided at the lower end of the bottom bracket.

[0024] According to the above description and practice, the mobile precast component transfer device described in the present utility model has the following advantages:

[0025] 1. The mobile precast component transfer device can be used alone or in combination according to requirements, and can be applied to precast components of different sizes and weights, forming stable support for them and carrying out transfer operations.

[0026] 2. In the mobile precast component transfer device, the support beam, bottom support and free wheels adopt a detachable 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.

[0027] 3. Based on the rotational degrees of freedom of the free wheels and the support beam relative to the bottom support, the transfer device can achieve horizontal free rotation to meet the transfer requirements in different directions.

[0028] 4. When the mobile precast component transfer device is in use, for precast components with relatively small weights, it can be pulled or pushed by hand, and the transfer of precast components can be completed by manpower, with stronger applicability.

[0029] 5. The requirements for lifting equipment and lifting personnel during the transfer process of precast components are reduced, the danger is reduced, and the whole process is operated on the ground surface, which is not easy to cause damage to precast components. In addition, compared with multiple people controlling multiple lifting devices, the manpower consumption is reduced, the labor cost and expenditure are saved, and the use cost of construction machinery is saved.

[0030] 6. The mobile precast component transfer device is easy to use, safe and efficient, and significantly improves the construction efficiency and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Embodiment 1

[0050] In this embodiment, a mobile precast component transfer device is provided, as Figures 1 to 5 shown. The transfer device includes a support beam 2 and three free wheel groups provided at its lower end. Each free wheel group includes a bottom support 1 and a free wheel 3. Specifically, three free wheel groups are rotatably provided at the lower end of the support beam 2, which can provide stable support for the device and facilitate transfer.

[0051] The upper end surface of the support beam 2 is a support surface in contact with the precast component to be transferred. An axially recessed shaft hole 22 is provided at the lower end of the support beam 2. A first rotating shaft 12 is formed on the upper side of the bottom support 1 in each free wheel group and is rotatably connected in the shaft hole 22. A first connecting member 11 is formed on the lower side of the bottom support 1. The upper end of the free wheel 3 is formed with a second rotating shaft 31 rotatably provided in the first connecting member 11. When the bottom support 1 is rotatably connected to the support beam 2, the two can rotate axially relative to each other around the first rotating shaft 12, while the relative movement in the radial direction is restricted. Similarly, when the free wheel 3 is rotatably connected to the bottom support 1, the two can rotate axially relative to each other around the second rotating shaft 31, while the relative movement in the radial direction is restricted.

[0052] The mobile precast component transfer device can be applicable to the transfer operations of precast components of different sizes and weights. For relatively large precast components, multiple such mobile precast component transfer devices can be evenly placed under the precast component to form a support for the precast component, and then the precast component can be pushed or pulled to transfer it. For precast components of other sizes and weights, the number of the mobile precast component transfer devices can be appropriately increased or decreased, and the transfer operation can also be carried out in the above manner.

[0053] As an embodiment, the first connecting member 11 is of a columnar structure, and a circular groove for accommodating the second rotating shaft 31 is formed inside. The second rotating shaft 31 is inserted into the second connecting member. This structural form can not only stably realize the rotational connection between the bottom tray 1 and the free wheel 3, but also the bottom tray 1 and the free wheel 3 are connected in a plug-in manner, 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.

[0054] As an embodiment, two or more 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 component to be transferred is small, setting one such mobile precast component transfer device under it can realize the transfer operation, and two or more free wheels 3 can ensure that the mobile precast component transfer device is not easily overturned 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 can be installed in the corresponding first connecting members 11 to more stably transfer the precast component.

[0055] Furthermore, as shown in Figure 5 In this embodiment, the free wheel 3 includes a main body structure 32 and rollers 33 arranged on both sides thereof, 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 of 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 manufactured at a relatively low cost. This structural form of the free wheel 3 can be applicable to the transfer operations of relatively heavy precast components. For relatively light precast components, the free wheel 3 can also be selected as a common universal wheel on the market, and the transfer operation of the precast component can also be realized at a relatively low cost.

[0056] As an embodiment, an anti-slip pad is provided on the upper surface of the support beam 2 or an anti-slip surface is formed, which can make the precast component to be transferred contact the support beam 2 more closely and firmly, and prevent the precast component from slipping off the support beam 2 during the transfer operation.

[0057] As an embodiment, a towing hole 13 is formed at one end of the bottom support 1. This facilitates the user to connect the transfer device to a power device through a connecting member such as a rod or a rope, and can further improve the efficiency of transporting precast components. For example, during the transfer operation, the transfer device is connected to a tractor through a rope. At this time, the traction force is applied to the transfer device rather than the precast component. On the one hand, it can avoid damaging the precast component, and on the other hand, it can also be applied to the transfer operation of heavier precast components.

[0058] It should be noted that the number of free wheel groups can be determined according to the actual situation. For example, when the length of the support beam 2 is relatively large, appropriately increasing the number of free wheel groups can improve the stability of the support for the precast component.

[0059] Embodiment 2

[0060] In this embodiment, another mobile precast component transfer device is provided. As Figures 6 to 9 shown, the transfer device includes a support beam 2, a connecting beam 6, and free wheel groups. The number of support beams 2 is more than two, and two adjacent support beams 2 are fixed together by the connecting beam 6. Specifically, the two side ends of the connecting beam 6 are connected to the support beam 2. Three free wheel groups are provided at the lower end of each support beam 2, and each free wheel group includes a bottom support 1 and a free wheel 3. Specifically, three free wheel groups are rotatably provided at the lower end of the support beam 2, which can provide stable support for the device and facilitate transfer.

[0061] As an embodiment, a slot 21 is formed on the side surface of the support beam 2, and a plug 61 that can be inserted into the slot 21 is formed at the side end of the connecting beam 6. Through the plug-in connection method, they can be quickly assembled together to form a stable overall support structure for transferring larger precast components. When the precast component is larger or there are more precast components, the number of support beams 2 can be increased. As Figure 8a and Figure 8b shown, the transfer device therein includes three support beams 2 and two connecting beams 6, and can transfer two relatively large strip-shaped precast components simultaneously.

[0062] As an embodiment, the connecting beam 6 includes a first beam body and a second beam body arranged longitudinally and transversely respectively. When in use, it not only plays the role of connecting two support beams 2, but also can, to a certain extent, support the precast component above, making the precast component more stable during the transfer process.

[0063] As an embodiment, a rotating joint 4 and a towing rod 5 are provided on a free wheel group. As Figure 8b and Figure 9As shown, one end of the rotating joint 4 is provided with a through hole opposite to the traction hole 13 and is rotationally connected to the traction hole 13 through a connecting shaft, so that the rotating joint 4 can rotate around the first direction and the axial direction of the connecting shaft. The other end of the rotating joint 4 is rotationally connected to one end of the traction rod 5, and the two can rotate relative to each other along the second direction.

[0064] In this embodiment, the first direction is the vertical direction and the second direction is the horizontal direction. When transferring precast components, the traction rod 5 can swing left and right and up and down, which is convenient for operators 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 as the numerical direction, and the above technical effects can also be achieved.

[0065] When using this mobile precast component transfer device for transfer operations, the operator only needs to pull or push one end of the traction rod 5 to drive the precast component on the support beam 2 to move, which can transfer the precast component more conveniently and is not likely to damage the precast component. It is particularly suitable for precast components with relatively small weights and can quickly complete the transfer operation.

[0066] 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 the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. 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, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
