Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, specifically to a ground-mounted screw support mechanism for a small-space trolley. Background Technology

[0002] During the secondary lining construction of tunnels, the secondary lining formwork must be firmly supported to ensure the quality of the finished product. To prevent the formwork from shrinking inwards, it must be supported against the ground. Currently, the common practice is to drill holes in the concrete ground for support, but this method has several significant drawbacks. First, it damages the backfill layer, affecting the integrity and stability of the ground structure, requiring secondary treatment of the backfill layer later, which is time-consuming and labor-intensive. Second, the construction process is cumbersome, increasing workload and construction costs. Third, traditional support methods are poorly adaptable to single-track trolleys or confined working environments, and may interfere with tracks and other facilities in the construction area, affecting vehicle traffic and construction progress. Furthermore, traditional support mechanisms require manual handling when moved, which is not only labor-intensive but also reduces construction efficiency. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a ground-mounted screw support mechanism for a small-space trolley. This mechanism eliminates the need to drill holes in the concrete floor, protects the integrity of the floor structure, reduces damage to the floor, and lowers the cost and workload of subsequent floor repairs. It is particularly suitable for single-line trolleys and small-space operating environments, solves the adaptability problem of traditional support methods in small-space scenarios, expands the application range of trolleys, and effectively solves the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a ground-mounted screw support mechanism for a small-space trolley, comprising a trolley template, trolley tracks, and a trolley; the trolley template is laid on the inner wall of the tunnel, the trolley tracks are laid on the tunnel floor, and the trolley travels on two trolley tracks; several transition beams are provided between the two trolley tracks, the transition beams are laid on the tunnel floor, and both ends of the transition beams are connected to the support members through ground-mounted screw assemblies and abut against the support trolley template.

[0005] Preferably, the grounding screw assembly includes a threaded sleeve and two screws. One end of the two screws is threadedly connected to the threaded sleeve. When the threaded sleeve is rotated, the two screws move closer or further apart. The other ends of the two screws are respectively connected to the transition beam and the support member through support lugs.

[0006] Preferably, both the transition beam and the support member are welded with support lugs, and the end of the screw is pinned to the support lugs via a pin.

[0007] Preferably, the transition beam is perpendicular to the trolley track, and the two sides of the transition beam have slopes.

[0008] Preferably, the lower end of the trolley template is provided with a slot, and the support member is an I-beam that fits into the slot.

[0009] Preferably, the transition beam is also equipped with a tension chain, which is connected to the portal legs of the trolley. When the trolley moves, the tension chain drives the transition beam to move accordingly.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Avoid damage to the backfill layer: There is no need to drill holes in the concrete floor, which protects the integrity of the floor structure, reduces damage to the floor, and lowers the cost and workload of subsequent floor repairs; 2. Ensure track access: The track can be installed across the rails without affecting their normal use, ensuring smooth vehicle passage and maintaining smooth traffic flow in the construction area; 3.

[0013] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0014] Please see Figure 1-3 The present invention provides the following technical solution: Example 1: A ground-mounted screw support mechanism for a small space trolley, comprising a trolley template 4, a trolley track 5, and a trolley 6; the trolley template 4 is laid on the inner wall of the tunnel, the trolley track 5 is laid on the tunnel floor, and the trolley 6 travels on two trolley tracks 5; several transition beams 1 are provided between the two trolley tracks 5, the transition beams 1 are laid on the tunnel floor, and both ends of the transition beams 1 are connected to the support members 7 through ground-mounted screw assemblies 3 and abut against the support trolley template 4; Specifically, the ground-aligning screw assembly 3 includes a threaded sleeve and two screws. One end of each screw is threadedly connected to the threaded sleeve. By rotating the threaded sleeve, the two screws move closer or further apart. The other ends of the two screws are respectively connected to the transition beam 1 and the support member 7 via the support ear plate 2. That is, by rotating the threaded sleeve, the ground-aligning screw assembly 3 acts on the support member 7, which in turn abuts against and supports the trolley template 4. This eliminates the need to drill holes in the concrete ground, protecting the integrity of the ground structure, reducing damage to the ground, and lowering the cost and workload of subsequent ground repair. From a stress perspective, since the forces on both sides of the trolley template 4 act on the transition beam 1, this structural design ensures the symmetry and stability of the trolley's stress, making the trolley more stable during operation. This support method has significant advantages for single-line trolleys or small-space scenarios, and can adapt well to confined working environments, reducing the occupation of construction space. Furthermore, the lower end of the trolley template 4 is provided with a slot, and the support member 7 is an I-beam that fits into the slot; both the transition beam 1 and the support member 7 are welded with support ear plates 2, and the end of the screw is pinned to the support ear plate 2 through a pin shaft.

[0015] Example 2: Unlike Example 1, the transition beam 1 is perpendicular to the trolley track 5. The two sides of the transition beam 1 have slopes. The transition beam 1 is located between the two trolley tracks 5. There is a distance between the end of the transition beam 1 and the trolley track 5. The design of the transition beam 1 allows it to cross the trolley track 5, thus avoiding obstruction to the trolley track 5 and ensuring the normal use of the track. The surface of the transition beam 1 is sloped to facilitate vehicle passage. When a vehicle passes, it can drive directly over the transition beam 1.

[0016] Example 3: Unlike Example 1, the transition beam 1 is also equipped with a tension chain. The tension chain is connected to the portal legs of the trolley 6. When the tension chain is retracted, the transition beam 1 can be moved upward and lifted off the ground. When the trolley 6 moves, the tension chain drives the transition beam 1 to move along with it, realizing the linkage movement of the transition beam 1 and the trolley 6, reducing the handling work of the transition beam 1, saving manpower, and improving construction efficiency.

[0017] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents in the content of this utility model.
