Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a tunnel construction arch block clamping device. Background Technology

[0002] Precast invert blocks are required during tunnel construction. The precast invert blocks are produced outside the tunnel and then hoisted into the tunnel for installation using hoisting equipment. This can shorten the construction period and reduce the workload of construction workers. When installing the precast invert blocks, two sets of invert blocks are tightened by a clamping structure to prevent water leakage from the tunnel invert later. For example, Chinese Patent CN212716655U discloses a novel installation pre-tightening device for precast invert blocks in railway tunnels, belonging to the technical field of railway tunnel construction. It addresses the technical problem of water leakage and seepage caused by insufficient compression between sections during the laying of existing precast invert blocks in railway tunnels. One end of the connecting seat is fixed with a cross brace, and a tightening device is installed at the lower part of the cross brace. The connecting seat is detachably connected to the precast invert block. The precast invert block has several track grooves for installing transport rails. The connecting seat is installed in the track grooves, and one end of the connecting seat is fixed to the installed invert block. The tightening device is installed between the precast invert block and the cross brace. This invention provides axial pre-tightening force between the invert blocks through the tightening device, compressing the waterstop between the invert blocks. It is then secured with a first bolt and a second bolt, improving the sealing and waterproofing between the invert block sections, effectively preventing leakage, improving construction quality, reducing manufacturing costs, facilitating use, and increasing the installation efficiency of the precast invert blocks. Based on existing solutions and actual production and processing, the existing tunnel construction invert block clamping device is inconvenient to move the clamping structure. When laying another set of invert precast blocks, the clamping structure will affect the laying of the invert precast blocks, and it is inconvenient to remove the clamping structure. Therefore, we propose a tunnel construction invert block clamping device to solve the problems mentioned above. Utility Model Content

[0003] The purpose of this utility model is to provide a tunnel construction invert arch block clamping device to solve the problems mentioned in the background art, such as the inconvenience of moving the clamping structure, the impact of the clamping structure on the laying of another set of invert arch precast blocks, and the inconvenience of removing the clamping structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tunnel construction invert block clamping device, comprising a first invert block, a second invert block, a connecting seat, and a hydraulic cylinder: A second inverted arch block is provided on the outside of the first inverted arch block, and a track groove is provided inside both the first inverted arch block and the second inverted arch block. A connecting seat is provided on the inner side of the track groove. A screw hole is opened inside the connecting seat. A mounting plate is fixed on the front side of the connecting seat. A roller is installed at the bottom end of the mounting plate. A hydraulic cylinder is fixed on the rear side of the connecting seat. A connecting block is fixed at the rear end of the hydraulic cylinder. A combination block is connected to the rear end of the connecting block. A side plate is vertically fixed on the rear side of the combination block. A rubber plate is connected to the front side of the side plate.

[0005] The above technical solution facilitates the movement of the clamping structure, and makes it easy to remove the influence of the clamping structure when laying another set of precast invert arch blocks.

[0006] Preferably, the track groove is symmetrically arranged about the center line of the first inverted arch block, so that the clamping structure composed of connecting seat, mounting plate, roller, hydraulic cylinder, connecting block, combination block, side plate and rubber plate is symmetrically installed on the first inverted arch block.

[0007] Preferably, the connecting seat is fixedly connected to the first arch block by screws, which facilitates the fixing of the first arch block and the connecting seat.

[0008] Preferably, the length of the roller is smaller than the width of the track groove, so that the roller is located inside the track groove and can move within the track groove.

[0009] Preferably, the combination block and the connecting block are connected by a snap-fit ​​connection, which facilitates the assembly and disassembly of the combination block and the connecting block.

[0010] Preferably, the front side of the rubber plate is in close contact with the rear side of the second arch block, and the gap between the first arch block and the second arch block is reduced by a hydraulic cylinder.

[0011] Preferably, the rubber sheet is fixed to the front side of the side plate by adhesive bonding, which facilitates the installation of new rubber sheets.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the tunnel construction invert arch block clamping device facilitates the movement of the clamping structure, and facilitates the removal of the clamping structure when laying another set of invert arch precast blocks; 1. A mounting plate is fixed to the front side of the connector, and a roller is installed at the bottom of the mounting plate. When it is necessary to move the connector, lift the connector slightly upward so that the connector is no longer in contact with the track groove, and then drag the connector. The roller makes it easy to move the connector. 2. The connection between the modular block and the connecting block is a snap-fit ​​connection. After the second invert block is brought close to the first invert block, when the next set of precast invert blocks needs to be laid, the modular block is removed from the connecting block, which can avoid the influence of the modular block, side plate and rubber plate on the next set of invert blocks. 3. The rubber sheet is fixed to the front side of the side panel by adhesive bonding. When the rubber sheet is damaged, it can be removed from the side panel for easy replacement with a new rubber sheet. Attached Figure Description

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 1-5 The existing tunnel construction invert arch block clamping device is inconvenient to move the clamping structure. When laying another set of invert arch precast blocks, the clamping structure will affect the laying of the invert arch precast blocks, and it is inconvenient to remove the clamping structure. In order to solve this technical problem, this embodiment discloses the following technical content. It includes a first inverted arch block 1, a second inverted arch block 2, a track groove 3, a connecting seat 4, a mounting plate 5, a roller 6, a hydraulic cylinder 7, a connecting block 8, a combination block 9, a side plate 10, a rubber plate 11, and screws 12; A second inverted arch block 2 is provided on the outside of the first inverted arch block 1. The first inverted arch block 1 is an installed inverted arch prefabricated block, and the second inverted arch block 2 is an inverted arch prefabricated block to be installed. Track grooves 3 are opened inside the first inverted arch block 1 and the second inverted arch block 2. A connecting seat 4 is provided on the inner side of the track groove 3. A screw hole is opened inside the connecting seat 4. A mounting plate 5 is fixed on the front side of the connecting seat 4. A roller 6 is installed at the bottom end of the mounting plate 5. A hydraulic cylinder 7 is fixed on the rear side of the connecting seat 4. A connecting block 8 is fixed on the rear end of the hydraulic cylinder 7. A combination block 9 is connected to the rear end of the connecting block 8. A side plate 10 is vertically fixed on the rear side of the combination block 9. A rubber plate 11 is connected to the front side of the side plate 10. After the second inverted arch block 2 is hoisted onto the outside of the first inverted arch block 1 using hoisting equipment, the connecting seat 4 is placed on the track groove 3 and the connecting seat 4 is fixed to the first inverted arch block 1 with screws 12. The track groove 3 is symmetrically arranged about the center line of the first inverted arch block 1, so that two sets of connecting seats 4 are symmetrically installed on the first inverted arch block 1. The length of the roller 6 is smaller than the width of the track groove 3, so that the roller 6 is located on the inside of the track groove 3. At this time, the front side of the rubber plate 11 is in contact with the rear side of the second arch block 2. Under the action of the hydraulic cylinder 7, the second arch block 2 is pressed against the first arch block 1, reducing the gap between the first arch block 1 and the second arch block 2. The connection between the assembly block 9 and the connecting block 8 is a snap-fit ​​connection. After the second inverted arch block 2 is installed, the connecting block 8 is moved backward under the action of the hydraulic cylinder 7, causing the rubber plate 11 to leave the second inverted arch block 2. Then, the connecting seat 4 is rotated upward, causing the connecting seat 4 to leave the track groove 3, with only the roller 6 in contact with the upper surface of the track groove 3. The connecting seat 4 is tilted and moved, relying on the roller 6 to easily move it to the connecting seat 4. Then, the assembly block 9 is lifted, as shown in the image. Figure 3 As shown, remove the assembly block 9, remove the influence of the assembly block 9, side plate 10 and rubber plate 11, and then lay another set of precast invert arch blocks to be installed. The rubber sheet 11 is fixed to the front side of the side plate 10 by adhesive bonding. When the rubber sheet 11 is worn, the rubber sheet 11 can be removed from the side plate 10 and a new rubber sheet 11 can be attached. The above completes a series of operations for the inverted arch block clamping device in tunnel construction.
