Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a dual-purpose device for hanging and supporting a track plate. Background Art

[0002] At present, in the construction of prefabricated track slabs, due to the large mass of a single prefabricated track slab, it is difficult to lift and transport it together with the rails and fasteners to form a finished track row, and the slabs need to be transported and adjusted separately.

[0003] In the related technologies, the traditional construction process of prefabricated track slab ballast bed mostly uses ordinary lifting ears to lift and transport the track slabs. First, a single track slab is transported to the working surface and laid flat. Then, the ordinary lifting ears are replaced with special lifting ears for track lifting. The special lifting ears are supported by support screws. The track slab is adjusted by adjusting the lifting and lowering of the support screws.

[0004] With regard to the above-mentioned related technologies, during the construction of the track slab roadbed, different types of lifting ears are required for hoisting and adjusting the track slabs. The types of lifting ears need to be frequently disassembled and replaced on the bolt holes, which can easily cause damage to the bolt holes and affect the safety of the track slab installation. At the same time, each replacement of the lifting ears takes a lot of time, which reduces the installation efficiency of the track slab. Therefore, there are problems such as insufficient safety and efficiency of the track slab installation.

[0005] In view of this, it is indeed necessary to provide a technical solution for solving the above-mentioned problems by providing a dual-purpose track plate suspension support device. Utility Model Content

The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0019] The following is combined with Figure 1-2 , further details of this application are given.

[0020] The present application provides a dual-purpose track plate suspension support device, which adopts the following technical solution:

[0021] Reference Figure 1 The track plate suspending and supporting dual-purpose device comprises a lifting ear base plate 1. The lifting ear base plate 1 is integrally formed and comprises a semicircular piece and a rectangular piece. A lifting hole 2 is provided on the semicircular piece of the lifting ear base plate 1, and the lifting hole 2 is provided for the connection of an external hook. A mounting hole 3 is provided on the rectangular piece of the lifting ear base plate 1, and a lifting ear bolt 4 is passed through the mounting hole 3. The lifting ear bolt 4 is connected with the bolt hole on the side of the track plate to fix the lifting ear base plate 1 on the side of the track plate. In production, in order to make the track plate bear force evenly, the lifting ear base plates 1 are usually symmetrically installed on both sides of the track plate.

[0022] Further, refer to Figure 2 The lifting hole 2 is located on the center line 11 of the lifting ear base plate 1, and two mounting holes 3 are provided. The two center holes are respectively located on both sides of the center line 11 of the lifting ear base plate 1, and the two mounting holes 3 are symmetrical about the center line 11 of the lifting ear base plate 1, so that the connecting line of the lifting hole 2 and the two mounting holes 3 forms an isosceles triangle, so that the lifting ear base plate 1 is not easy to flip over during the lifting process, so that the lifting ear bolts 4 on the two mounting holes 3 are evenly stressed, reducing the damage to the bolt holes on the track plate, thereby reducing the occurrence of lifting safety accidents and improving the safety of track plate installation.

[0023] Reference Figure 1 and Figure 2The side of the mounting hole 3 is provided on the lifting ear bottom plate 1, extending outward and protruding, and a support block 5 is installed integrally. The support block 5 is a rectangular parallelepiped, and a screw rod 6 is passed through the support block 5. A threaded hole is provided on the top surface of the support block 5. The screw rod 6 is threadedly connected to the inner wall of the threaded hole. The screw rod 6 moves up and down relative to the support block 5, and the bottom end of the screw rod 6 is supported on the working surface. In this embodiment, the working surface is the structural bottom plate.

[0024] Further, refer to Figure 1 and Figure 2 The bottom end of the screw rod 6 is integrally formed with a polished rod 7, the peripheral side of the polished rod 7 is a smooth surface, the diameter of the polished rod 7 is smaller than the diameter of the screw rod 6, and the polished rod 7 is inserted into the structural hole of the working surface. On the one hand, the screw rod 6 is supported on the working surface more stably, and on the other hand, the screw rod 6 can rotate relative to the working surface, thereby improving the stability of the support lifting and lowering, and improving the safety of the track plate installation.

[0025] Furthermore, refer to Figure 1 and Figure 2 , a tool column 8 is integrally formed at one end of the screw rod 6 away from the polished rod 7. The tool column 8 includes a cylinder and a hexagonal prism 82. A tool hole 81 is provided on the side of the cylinder. The tool hole 81 is a round hole, and the size of the hexagonal prism 82 matches the electric wrench. When threaded transmission is required to change the height of the track plate, by inserting tools such as a crowbar and a steel pipe into the tool hole 81 of the cylinder, the screw rod 6 can be rotated more labor-savingly. By connecting the electric wrench to the hexagonal prism 82, the screw rod 6 can be driven to rotate quickly, thereby improving the efficiency of adjusting the height of the track plate, which is conducive to improving the installation efficiency of the track plate.

[0026] When the track plate needs to be installed, the lifting lug base plate 1 is aligned with the side of the track plate, the mounting hole 3 of the lifting lug base plate 1 is aligned with the bolt hole of the track plate, the lifting lug bolt 4 is screwed into the bolt hole, the lifting lug base plate 1 is fixed to the side of the track plate, and the screw rod 6 is threadedly connected to the support block 5 of the lifting lug base plate 1. When hoisting, the crane hook is inserted into the hoisting hole 2, the track plate is transported to the working surface by the crane, the light rod 7 is inserted into the structural hole on the working surface, and the screw rod 6 stably supports the track plate on the working surface, thereby completing the hoisting and transportation steps; when adjusting the plate, the screw rod 6 is driven to rotate by tools such as an electric wrench or a crowbar, and the track plate is driven to rise and fall relative to the screw rod 6 by threaded transmission, thereby completing the adjustment plate installation step. During the transportation and installation of the track plate, there is no need to switch the lifting lug type between the lifting and supporting steps, which reduces the number of disassembly and connection times of the bolt holes and reduces damage to the bolt holes, thereby improving the safety of the track plate installation. At the same time, it reduces the working hours consumed in changing the lifting lug type and reduces the time for track plate installation, thereby improving the installation efficiency of the track plate.

[0027] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
