Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment, and in particular to a lightweight tunnel lining model trolley. Background Technology

[0002] In traditional tunnel construction, tunnel lining model trolleys serve as crucial construction equipment, undertaking the important task of supporting and shaping the tunnel's inner walls. Traditional tunnel lining model trolleys typically employ a rail-based system, where the trolley travels on pre-set rails via steel wheels to move and position the lining templates within the tunnel. However, this rail-based system has several shortcomings.

[0003] First, the installation and maintenance costs of the rail system are high. Rails need to be laid in advance before tunnel construction, which not only increases preparation time but also raises the overall project cost. Furthermore, as tunnel construction progresses, the rails may need continuous adjustments or extensions, further increasing the complexity and workload of maintenance.

[0004] Secondly, the flexibility of the rail system is limited. Due to the fixed nature of the rails, the trolley must strictly follow the rail track during travel, which restricts its use in tunnels with non-linear or complex terrain. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight tunnel lining model trolley to solve the technical problems of high installation and maintenance costs and limited flexibility of traditional lining model trolleys that use a rail walking system.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a lightweight tunnel lining model trolley, the lightweight tunnel lining model trolley comprising:

[0007] A gantry assembly, wherein a vehicle passage is provided at the bottom of the gantry assembly;

[0008] Template, the template being installed on the gantry assembly via a hydraulic device;

[0009] The main traveling mechanism is mounted on the gantry assembly. The main traveling mechanism includes a steel wheel and a translation cylinder. The steel wheel is rotatably mounted on the bottom end of the gantry assembly and supports the gantry assembly. The cylinder body of the translation cylinder is hinged to the gantry assembly, and the piston rod of the translation cylinder rests against the concrete ground.

[0010] In one embodiment, the main walking mechanism further includes an anti-slip plate, which is disposed between the piston rod of the translation cylinder and the concrete ground. The piston rod of the translation cylinder is hinged to the anti-slip plate, and the bottom surface of the anti-slip plate is provided with anti-slip spikes.

[0011] In one embodiment, the main traveling mechanism further includes a control cylinder, the cylinder body of which is hinged to the gantry assembly, and the piston rod of which is hinged to the cylinder body of the translation cylinder.

[0015] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages:

[0029] Please see Figures 1 to 4This application provides a lightweight tunnel lining model trolley, including a gantry assembly 1, a template 2, and a main traveling mechanism 3. The gantry assembly 1 has a vehicle passageway 11 at its bottom. The template 2 is mounted on the gantry assembly 1 via a hydraulic device. The main traveling mechanism 3 is mounted on the gantry assembly 1 and includes steel wheels 31 and a translation cylinder 32. The steel wheels 31 are rotatably mounted on the bottom end of the gantry assembly 1, supporting the gantry assembly 1. The cylinder body of the translation cylinder 32 is hinged to the gantry assembly 1, and the piston rod of the translation cylinder 32 rests against a concrete surface 4.

[0030] In this embodiment, the main traveling mechanism 3 drives the trolley to move, and the translation cylinder 32 provides the gantry assembly 1 with the traveling thrust, so that the gantry assembly 1 on the steel wheel 31 moves, eliminating the track structure of the traditional steel rail trolley, so that the gantry assembly 1 can move freely without steel rails.

[0031] Specifically, when the lining model trolley is pouring concrete, such as Figure 1-2 As shown, at this time, the translation cylinder 32 is vertically oriented towards the concrete ground 4, providing upward support to the gantry assembly 1 and improving the stability of the gantry assembly 1 during concrete pouring. When the concrete has solidified and the lining model trolley needs to be moved forward, simply control the translation cylinder 32 to retract first, causing the piston rod end of the translation cylinder 32 to detach from the concrete ground 4, and then tilt the translation cylinder 32 backward (as shown). Figure 3-4 As shown, a backward force can be applied to the translation cylinder 32 manually or by other means, causing the translation cylinder 32 to tilt backward. Then, the piston rod of the translation cylinder 32 extends until it again touches the concrete surface 4. At this point, as the translation cylinder 32 continues to extend, it applies a forward-sloping upward thrust to the lining model trolley, causing it to move forward. After moving a certain distance, the translation cylinder 32 can be retracted again to adjust its support point on the concrete surface 4. Then, the translation cylinder 32 can be extended again to allow the lining model trolley to continue moving forward until it reaches the next pouring point.

[0032] In one embodiment, the main traveling mechanism 3 further includes an anti-slip plate 33, which is disposed between the piston rod of the translation cylinder 32 and the concrete ground 4. The piston rod of the translation cylinder 32 is hinged to the anti-slip plate 33, and the bottom surface of the anti-slip plate 33 is provided with anti-slip teeth. By providing the anti-slip plate 33, the friction between the piston rod of the translation cylinder 32 and the concrete is increased, making it less likely for the translation cylinder 32 to slip when driving the lining model trolley, thus making the main traveling mechanism 3 more stable and reliable.

[0033] In one embodiment, the main traveling mechanism 3 further includes a control cylinder 34, the cylinder body of which is hinged to the gantry assembly 1, and the piston rod of which is hinged to the cylinder body of the translation cylinder 32. When the model trolley needs to move, the piston rod of the translation cylinder 32 first retracts, causing the end of the piston rod of the translation cylinder 32 to detach from the concrete ground 4. Then, the control cylinder 34 retracts, causing the translation cylinder 32, which was originally perpendicular to the concrete ground 4, to tilt backward. Then, the piston rod of the translation cylinder 32 extends until it abuts against the concrete ground 4. At this point, the control cylinder 34 is depressurized (no longer restricting the translation cylinder 32 to rotate along its hinge point with the gantry assembly 1). Figure 5 As shown, the piston rod of the translation cylinder 32 then continues to extend until the lining model trolley completes one forward movement. The piston rod of the translation cylinder 32 then retracts again, controlling the extension of the piston of cylinder 34, causing the translation cylinder 32 to return to its original position. Figure 5 As shown in the tilting situation, the piston rod of the translation cylinder 32 extends until it touches the concrete ground 4 again. Then, the control cylinder 34 is depressurized again, and the piston rod of the translation cylinder 32 continues to extend, which drives the lining model trolley to move forward again. By repeating the above steps, the lining model trolley can be made to move forward continuously.

[0034] Since both sides of the gantry assembly 1 are equipped with translation cylinders 32, when it is necessary to turn the lining model trolley, it is only necessary to control the translation cylinder 32 on one side to drive the lining model trolley, so that the lining model trolley can turn to the other side. When the translation cylinders 32 on both sides drive the lining model trolley at the same time, the lining model trolley travels forward in a straight line.

[0035] In one embodiment, the main traveling mechanism 3 further includes a hydraulic control system, which is connected to the translation cylinder 32 and the control cylinder 34. The hydraulic control system controls the operation of the translation cylinder 32 and the control cylinder 34. The hydraulic control system can control the translation cylinder 32 and the control cylinder 34 according to a preset program, thereby controlling the movement of the lining model trolley and thus realizing automated control of the movement of the lining model trolley.

[0036] In one embodiment, the gantry assembly 1 includes longitudinal beams 12 and transverse beams 13, which are interconnected to form a stable frame structure. A vehicle passageway 11 is located at the bottom center of the frame structure. This design gives the gantry assembly 1 excellent structural stability and load-bearing capacity. The frame structure effectively distributes and bears various loads from the formwork 2 and during construction, ensuring the safety and reliability of the trolley during operation. Simultaneously, the vehicle passageway 11 facilitates the passage of construction personnel and equipment, improving construction efficiency.

[0037] In one embodiment, an arc-shaped reinforcing rib 14 is provided between the longitudinal beam 12 and the transverse beam 13. The arc-shaped reinforcing rib 14 between the longitudinal beam 12 and the transverse beam 13 further enhances the structural rigidity and torsional resistance of the gantry assembly 1. The arc-shaped reinforcing rib 14 can effectively resist the deformation and torsion that may occur in the gantry assembly 1 under stress, improving the overall stability and durability of the gantry assembly 1.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
