Description

Technical Field

[0001] This application relates to the field of bridge and tunnel construction, and in particular to a support device for bridge and tunnel construction. Background Technology

[0002] Tunnels are engineering structures buried in the earth's strata and are a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. Bridge tunnels are a type of traffic tunnel. During the construction of bridge tunnels, support equipment is one of the key tools to ensure construction safety and quality.

[0003] In bridge and tunnel construction, the support height of the support equipment will vary due to different construction progress. However, existing support equipment usually only has one support plate, which can only provide support at a single position. In order to adapt to different support heights, more support equipment needs to be set up, which not only affects construction efficiency but also increases construction costs. To solve the above problems, a support equipment for bridge and tunnel construction is proposed.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the aforementioned problems, this application provides a support device for bridge and tunnel construction.

[0007] A support device for bridge and tunnel construction includes a base, two movable frames on the top of the base and a movable component for driving the two movable frames to move closer or further apart, each of the two movable frames has a liftable support plate on its top, and a detachable support pad is provided between the two support plates, the support pad being flexible.

[0008] Preferably, the moving component includes a guide rail, a slider, rack one, rack two, a gear, and a cylinder. The top of the base is provided with a guide rail, and the moving frame can slide on the surface of the guide rail. The top of the base has a groove for the slider to slide. Rack one and rack two are respectively fixed on the sides of the two moving frames that are close to each other. The gear rotates on the top of the base and meshes with rack one and rack two simultaneously. The cylinder is fixed at the bottom of the base, and the telescopic end of the cylinder is fixed to the slider. The slider is fixed to the bottom of a moving frame away from the telescopic end of the cylinder.

[0009] Preferably, the top of the movable frame is provided with an electric push rod, and the telescopic end of the electric push rod is fixed with a connecting frame, which is fixed to the bottom of the support plate.

[0010] Preferably, both sides of the receiving pad are fixed with fixing blocks, and the two fixing blocks are respectively engaged with the two connecting frames. The top of the two connecting frames is rotatably provided with a limiting block, and the limiting block is threaded with a limiting pin. The bottom end of the limiting pin passes through the limiting block and is threadedly connected to the fixing block.

[0011] Preferably, the four corners of the bottom of the receiving pad are fixed to the bottom of the support plate by fasteners.

[0012] Preferably, the base is provided with casters at the bottom.

[0013] Preferably, both of the movable frames are provided with openings for rack one or rack two to pass through.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a support device for bridge and tunnel construction. (Refer to...) Figure 1-3 A support device for bridge and tunnel construction includes a base 1, with a movable wheel 19 at the bottom of the base 1. The movable wheel 19 is a swivel wheel with a self-locking function. Two movable frames 5 are provided on the top of the base 1. Each movable frame 5 is provided with an electric push rod 11. A connecting frame 12 is fixed to the telescopic end of the electric push rod 11. A support plate 13 is fixed to the top of the connecting frame 12. In use, the base 1 is pushed to move the support device to the corresponding bridge and tunnel construction site under the action of the movable wheel 19. The electric push rod 11 is activated to push the connecting frame 12 and the support plate 13 on it to support the top of the bridge and tunnel construction site.

[0022] It should be noted that, in order to ensure the stability of the support plate 13, the length of the connecting frame 12 can be matched with the length of the support plate 13.

[0023] Reference Figure 1-3 The base 1 has a moving assembly on its top that drives two movable frames 5 to move closer or further apart. The moving assembly includes a guide rail 2, a slider 4, a rack 6, a rack 7, a gear 8, and a cylinder 9. The guide rail 2 is located on the top of the base 1, and the movable frames 5 can slide on the surface of the guide rail 2. A groove 3 is provided on the top of the base 1 for the slider 4 to slide. Rack 6 and rack 7 are respectively fixed to the sides of the two movable frames 5 that are close to each other. The gear 8 rotates on the top of the base 1 via a connecting block, and simultaneously meshes with rack 6 and rack 7. The cylinder 9 is fixed to the bottom of the base 1, and the telescopic end of the cylinder 9 is fixed to the slider 4. The slider 4 and… A movable frame 5, located away from the telescopic end of cylinder 9, is fixed at the bottom. When it is necessary to support construction sections with different heights, cylinder 9 is activated, pushing slider 4 and its top movable frame 5 to move along the length of guide rail 2. This, in turn, pulls rack 6 to move synchronously, which in turn drives gear 8 to rotate. This causes rack 7 and its movable frame 5 to move along guide rail 2 away from rack 6, thereby moving the two support plates 13 away from each other. This facilitates providing multi-point support for the top of the bridge and tunnel construction site, reduces the adjustment time required for support equipment, improves construction efficiency, and avoids setting up too many support equipment.

[0024] Reference Figure 1 A support pad 15 is provided between the two support plates 13. The support pad 15 is flexible. When the two support plates 13 move away from each other, the support pad 15 is stretched synchronously to cover the gap between the two support plates 13, so as to avoid damage to the components on the base 1 caused by falling gravel and impurities during bridge and tunnel construction, and at the same time, to prevent gravel and impurities from falling and causing injury to construction personnel.

[0025] Reference Figure 1The receiving pad 15 has two fixing blocks 14 fixed on both sides. The two fixing blocks 14 are respectively engaged with the two connecting brackets 12. The top of the two connecting brackets 12 is provided with a limiting block 16. When the receiving pad 15 is fixed, one end of the limiting block 16 abuts against the top of the fixing block 14. The limiting block 16 is provided with a limiting pin 17 threaded on it. The bottom end of the limiting pin 17 passes through the limiting block 16 and is threadedly connected to the fixing block 14. The four corners of the bottom of the receiving pad 15 are fixed to the bottom of the support plate 13 by fasteners 18, so that the receiving pad 15 can completely cover the gap between the two support plates 13. When it is necessary to replace the receiving pad 15 or clean the gravel and impurities on the receiving pad 15, turn the limiting pin 17 to disconnect the threaded connection with the fixing block 14, move the limiting block 16 away from the fixing block 14, and turn or remove the fasteners 18 in sequence to release the fixation of the four corners of the receiving pad 15.

[0026] Reference Figure 1 , 2 Both movable frames 5 are provided with openings 10 for rack 6 or rack 7 to pass through. When the two support plates 13 are close to each other, the openings 10 can prevent the movement of rack 6 or rack 7 from conflicting with the movement of the movable frame 5 opposite to it.
