Description

Technical Field

[0001] This utility model belongs to the field of prefabricated track slab technology, specifically relating to a prefabricated track slab that is easy to lift and install. Background Technology

[0002] Precast track slabs are an important component of track engineering projects such as high-speed railways and urban rail transit. They are precast components produced in factories using precision molds. Precast track slabs are generally installed on the track. Steel rails are fixed to the surface of the precast track slabs using fasteners. A precast base plate is fixed between the track and the precast track slabs. The precast base plate and the precast track slabs are fixed together by drilling bolts. A precast track slab with pre-embedded channels is disclosed in document CN221918786U. The technology for laying precast track slabs on the track is the disclosed technology.

[0003] Precast track slabs have a certain weight. The installation of precast track slabs is generally carried out by lifting equipment. Usually, lifting rings are installed on the precast track slabs, and then the lifting hook is hooked onto the lifting rings. After the precast track slab is lifted into a suitable position, the hook is removed and the lifting rings are disassembled. The lifting process requires frequent disassembly and assembly of the lifting rings and bolts, which is quite cumbersome and inconvenient for the lifting and installation of precast track slabs. Existing precast track slabs lack a convenient lifting design during installation. Therefore, this application proposes a precast track slab that facilitates lifting and installation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 5 This utility model provides a technical solution: a prefabricated track slab that is easy to lift and install, including a prefabricated track slab component 1, such as... Figure 5 As shown, E represents the steel rail, A represents the precast track slab 1, B represents the vibration damping plate, C represents the precast base plate, and D represents the circular tunnel shield segment. The precast track slab 1 is installed inside the circular tunnel. The lifting and installation assembly includes a stabilizing block 2 fixed to the precast track slab 1 by bolts, locking bolts 8 penetrating the stabilizing block 2, lifting steel bars 5 penetrating both ends of the stabilizing block 2, and limiting components, such as... Figure 2 As shown, the end of the hoisting reinforcing bar 5 is installed inside the stabilizing block 2. A locking bolt 8 supports the end of the hoisting reinforcing bar 5, and a limiting component restricts the end of the hoisting reinforcing bar 5 to prevent it from swaying. The locking bolt 8 is a hand-tightening type, allowing manual rotation to tighten or loosen it. This limiting component includes a guide rod 4 that slides through the stabilizing block 2 and a mounting plate 3 welded to one end of the guide rod 4. The end of the hoisting reinforcing bar 5 passes through the mounting plate 3, which supports it. The hoisting reinforcing bar 5 and the stabilizing block 2 are separate structures; the hoisting reinforcing bar 5 is detachable for reuse and facilitates lifting operations. The mounting plate 3 can be used with precast... The base plate C is fixed by mounting bolts b, increasing the number of firm points; the lifting connection includes a movable block 6 installed on the outside of the lifting steel bar 5 and a lifting ring 7 connected in combination with the movable block 6. The movable block 6 and the lifting steel bar 5 are combined, which facilitates the assembly and disassembly of the movable block 6. During lifting, the hook hooks the lifting ring 7, thereby achieving the function of hooking the lifting steel bar 5 and the prefabricated track slab 1. This application uses the lifting steel bar 5 to form a rigid lifting device, which reduces load swing compared to direct lifting with flexible steel wire rope. The rigid lifting device formed by the lifting steel bar 5 and the stabilizing block 2 can evenly distribute the force on the lifting point and reduce the swaying caused by uneven force.

[0017] In this embodiment, the lifting ring 7 includes a lifting ring 71, a fixing block 72, and a threaded post 73. The fixing block 72 is welded to the lifting ring 71 and the threaded post 73. The threaded post 73 is connected to the moving block 6 by threaded engagement. The lifting ring 7 and the moving block 6 are a combined structure. The lifting ring 7 and the moving block 6 are detachable, making it easy to replace them with different types of lifting devices.

[0018] In this embodiment, the surface of the movable block 6 is provided with a locking screw 61 for locking the hoisting steel bar 5. Under the action of the locking screw 61, the movable block 6 is fastened to the hoisting steel bar 5. By loosening the locking screw 61, the position of the movable block 6 on the hoisting steel bar 5 can be changed, which makes it easier to change the lifting point. By changing the force position of the lifting point, the load swing can be reduced.

[0019] In this embodiment, a blocking block 41 with a screw hole is welded to the end of the guide rod 4 away from the mounting plate 3. The blocking block 41 serves to limit and block, preventing the guide rod 4 from sliding off the stabilizing block 2.

[0020] In this embodiment, the mounting plate 3 has a right-angle structure, and a baffle 31 is welded to the surface of the side of the mounting plate 3. The baffle 31 serves to limit and block, thereby limiting the end of the hoisting steel bar 5. The stabilizing block 2 has a "U"-shaped structure. The mounting plate 3 has a through hole a in the center for the hoisting steel bar 5 to pass through. The hoisting steel bar 5 passes through the gap between the inner surface of the stabilizing block 2 and the locking bolt 8. The end of the hoisting steel bar 5 is supported, which facilitates the installation and removal of the hoisting steel bar 5. The top surfaces of the mounting plate 3, the stabilizing block 2, and the moving block 6 are flush. The mounting bolt b passes through the surface of the mounting plate 3. The mounting plate 3 is fixed to the precast base plate C by the mounting bolt b. The blocking block 41 is fixed to the precast base plate C by bolts. The mounting plate 3, the guide rod 4, the blocking block 41, and the stabilizing block 2 serve as reinforcement components to fix the precast track plate 1.

[0021] Working principle and usage process of this utility model: When the prefabricated track slab 1 is hoisted, the lifting ring 7 and the moving block 6 are combined to form an integral structure. Adjust the position of the moving block 6 on the hoisting steel bar 5 to change the lifting point and reduce load sway by changing the force position of the lifting point; like Figure 2 As shown, the end of the hoisting steel bar 5 is installed inside the stabilizing block 2. The mounting plate 3 moves, the hoisting steel bar 5 passes through the mounting plate 3, the mounting plate 3 supports the end of the hoisting steel bar 5, and the locking bolt 8 is tightened, so that the end of the hoisting steel bar 5 is supported. During lifting, the hook catches the lifting ring 7, thereby lifting the steel bar 5 and the precast track slab 1. The lifting steel bar 5 and the stabilizing block 2 in this application constitute a rigid lifting device. Compared with the direct lifting with flexible steel wire rope, it reduces load swing. The rigid lifting device composed of the lifting steel bar 5 and the stabilizing block 2 can evenly distribute the force on the lifting point and reduce the swaying caused by uneven force. Mounting plate 3, guide rod 4, blocking block 41, and stabilizing block 2 serve as reinforcement components to fix the precast track plate 1; In summary: The precast track slab has a lifting design that facilitates hoisting. The hoisting steel bar 5 and the stabilizing block 2 constitute a rigid lifting device. The hook hooks onto the lifting ring 7, and the lifting ring 7, the hoisting steel bar 5 and the stabilizing block 2 are lifted and hoisted, thereby hoisting the precast track slab 1.
