Description

Technical Field

[0001] This utility model relates to the field of pipe gallery installation technology, and in particular to an assembly structure for a prefabricated underground pipe gallery. Background Technology

[0002] Underground utility tunnels are public tunnels built underground in cities to centrally lay municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heating, and gas. Various construction and maintenance operations do not require repeated road excavation. Underground utility tunnels are composed of prefabricated box culvert structures, and usually require assembly structures to assemble adjacent prefabricated box culvert structures.

[0003] For example, Chinese patent "CN219637958U" discloses "a connecting frame for prefabricated pipe racks." This connecting frame inserts two pipe rack bodies into opposite sides of the frame, with the pipe body embedded in the groove and the inner pipe entering the interior of the pipe rack body. The frame and pipe rack body can then be connected using mounting bolts. However, the inner diameter of the connecting frame is the same as the outer diameter of the pipe rack body. During the hoisting and installation of the pipe rack body, it is not possible to quickly align the pipe rack body with the connecting frame, which is time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an assembly structure for prefabricated underground utility tunnels, which solves the problems of inconvenience and time-consuming connection of adjacent utility tunnel bodies via connecting frames in existing technologies.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] An assembly structure for a prefabricated underground utility tunnel, installed between adjacent tunnel bodies, includes:

[0007] The first connecting frame is installed at the end of one of the pipe rack bodies;

[0008] The second connecting frame is installed at the end of another pipe rack body, and when the two pipe rack bodies are connected, the second connecting frame is fitted onto the first connecting frame.

[0009] The limiting unit includes two fixed plates that are slidably disposed on the second connecting frame and located on both sides of the first connecting frame, and an adjusting member that is rotatably disposed on the second connecting frame. The adjusting member is connected to the fixed plates and is used to connect the fixed plates to the side of the first connecting frame.

[0010] Preferably, the adjusting component includes a drive plate connected to the fixed plate and an adjusting screw rotatably disposed in the second connecting frame, the adjusting screw being threadedly connected to the drive plate.

[0011] Preferably, a limiting block is fixedly provided on the side of the drive board near the first connecting frame, and a limiting groove corresponding to the limiting block is opened on the side of the first connecting frame, and the limiting block is engaged with the limiting groove.

[0012] Preferably, the second connecting frame is rotatably provided with a connecting rod, and the two ends of the connecting rod are respectively connected to two adjusting screws.

[0013] Preferably, the side of the second connecting frame is recessed inward to form a groove, and an adjusting nut is provided in the groove, which is connected to the adjusting screw.

[0014] Preferably, both the first connecting frame and the second connecting frame have a number of mounting holes for bolts to pass through.

[0015] Preferably, both the end faces of the first connecting frame and the end faces of the second connecting frame are provided with sealing grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this scheme, the first connecting frame and the second connecting frame are respectively installed at the ends of the two pipe rack bodies that need to be connected, and the first connecting frame is inserted through the second connecting frame. Since there is a certain distance between the first connecting frame and the second connecting frame, it is convenient to connect the pipe rack body with the first connecting frame to the pipe rack body with the second connecting frame during the hoisting process, which greatly improves the installation efficiency. At the same time, in order to compensate for the distance generated by the convenient connection between the first connecting frame and the second connecting frame, the corresponding fixing plates are adjusted by the adjusting parts under the action of the limiting unit, so that the fixing plates move to the side of the first connecting frame and connect with the first connecting frame, which can ensure the strength of the two pipe rack bodies after assembly.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown in the figure, this utility model embodiment proposes an assembly structure for a prefabricated underground utility tunnel, installed between adjacent utility tunnel bodies 1, including:

[0026] The first connecting frame 2 is installed at the end of one of the pipe rack bodies 1;

[0027] The second connecting frame 3 is installed at the end of another pipe rack body 1, and when the two pipe rack bodies 1 are connected, the second connecting frame 3 is fitted onto the first connecting frame 2.

[0028] The limiting unit includes two fixed plates 4 that are slidably disposed on the second connecting frame 3 and located on both sides of the first connecting frame 2, and an adjusting member that is rotatably disposed on the second connecting frame 3. The adjusting member is connected to the fixed plates 4 and is used to connect the fixed plates 4 to the side of the first connecting frame 2.

[0029] In the embodiments of this utility model, during the prefabrication process, grooves for installing the first connecting frame 2 and the second connecting frame 3 are respectively opened at both ends of the pipe gallery body 1, so that the first connecting frame 2 and the second connecting frame 3 are embedded in the grooves, and the first connecting frame 2, the second connecting frame 3 and the pipe gallery body 1 form an integral whole. When docking two adjacent pipe rack bodies 1, the end of one pipe rack body 1 with the second connecting frame 3 is aligned with the end of the other pipe rack body 1 with the first connecting frame 2. After one pipe rack body 1 has been installed, the other pipe rack body 1 is hoisted to the end of the first pipe rack body 1 using hoisting equipment. By gradually lowering the other pipe rack body 1, the first connecting frame 2 is gradually aligned with the second connecting frame 3. Since the lateral outer diameter of the first connecting frame 2 is smaller than the lateral inner diameter of the second connecting frame 3, the first connecting frame 2 can move a small distance within the second connecting frame 3. It is only necessary to ensure that the first connecting frame 2 and the second connecting frame 3 are flush vertically. The docking of the two pipe rack bodies 1 can be completed by directly pushing the other pipe rack body 1 into the installed first pipe rack body 1.

[0030] Secondly, in order to ensure the stability and neatness of the docking of the two pipe rack bodies 1, and to compensate for the distance caused by the first connecting frame 2 and the second connecting frame 3, the corresponding fixing plate 4 is adjusted by the adjusting component under the action of the limiting unit, so that the fixing plate 4 moves to the side of the first connecting frame 2 and connects with the first connecting frame 2. This can ensure the strength of the two pipe rack bodies 1 after assembly, and there are no protrusions on the inner and outer surfaces of the two pipe rack bodies 1 after docking, thus facilitating the installation and construction of the pipe rack bodies 1.

[0031] Based on the above solutions, such as Figure 3 and Figure 4 As shown, the adjusting component includes a drive plate 402 connected to the fixed plate 4 and an adjusting screw 5 rotatably disposed on the second connecting frame 3. The adjusting screw 5 is threadedly connected to the drive plate 402.

[0032] Specifically, when the fixing plate 4 is operated by the adjusting component, that is, after the first connecting frame 2 passes through the second connecting frame 3, the two adjusting screws 5 corresponding to the two fixing plates 4 are rotated respectively, so that the adjusting screws 5 rotate in the second connecting frame 3, and the driving plate 402 is limited and cannot rotate. Therefore, under the thread transmission of the adjusting screws 5, the driving plate 402 will move in the second connecting frame 3, thereby causing the driving plate 402 to drive the fixing plate 4 connected to it to move towards the first connecting frame 2 until it abuts, thus completing the limitation of the first connecting frame 2.

[0033] Meanwhile, the second connecting frame 3 is rotatably equipped with a connecting rod 502, the two ends of which are respectively connected to two adjusting screws 5. To simplify the process, when one of the adjusting screws 5 is rotated, it drives the other adjusting screw 5 to rotate through the connecting rod 502. This allows the two fixing plates 4 to move closer to the first connecting frame 2 simultaneously while one of the adjusting screws 5 is rotating. When the first connecting frame 2 is not centered, the first connecting frame 2 can be squeezed by one of the fixing plates 4 under the synchronous movement of the two fixing plates 4 until both fixing plates 4 are connected to the first connecting frame 2, thus completing the centering adjustment of the first connecting frame 2.

[0034] Specifically, such as Figure 3 and Figure 4As shown, a limiting block 401 is fixedly provided on the side of the drive plate 402 near the first connecting frame 2. A limiting groove 201 corresponding to the limiting block 401 is opened on the side of the first connecting frame 2. The limiting block 401 is engaged with the limiting groove 201. With the cooperation of the limiting block 401 and the limiting groove 201, the edge of the opening of the limiting groove 201 has a bevel, which can play a guiding role. When the end face of the first connecting frame 2 does not abut against the inside of the other pipe gallery body 1, the limiting block 401 cannot be engaged in the limiting groove 201, which plays a certain guiding role. Furthermore, under the action of the bevel, when there is a slight deviation between the limiting block 401 and the limiting groove 201, the guide of the bevel can make the limiting block 401 engage in the limiting groove 201. After the limiting block 401 engages in the limiting groove 201, it can increase the connection strength between the first connecting frame 2 and the second connecting frame 3, thereby ensuring the assembly quality of the pipe gallery body 1.

[0035] Specifically, such as Figure 3 As shown, the side of the second connecting frame 3 is recessed inward to form a groove, and an adjusting nut 501 is provided in the groove. The adjusting nut 501 is connected to the adjusting screw 5. The groove allows the adjusting nut 501 to be placed inside the second connecting frame 3. Furthermore, the adjusting nut 501 makes it easier to use tools to adjust the adjusting screw 5, saving effort. Moreover, a notch can be opened at one end of the pipe gallery body 1 where the second connecting frame 3 is installed to facilitate the adjustment of the adjusting nut 501.

[0036] Specifically, such as Figure 1 As shown, both the first connecting frame 2 and the second connecting frame 3 have several mounting holes 6 for bolts to pass through. Under the action of each mounting hole 6, when the first connecting frame 2 and the second connecting frame 3 are installed at both ends of the pipe gallery body 1, the first connecting frame 2 and the second connecting frame 3 can be fixedly installed by bolts to ensure strength and facilitate assembly.

[0037] Specifically, such as Figure 2 and Figure 5 As shown, sealing grooves 301 are provided on the end faces of the first connecting frame 2 and the second connecting frame 3. The sealing grooves 301 can accommodate sealing strips or sealing rings, which can ensure the sealing of the contact surfaces after the end faces of the first connecting frame 2 and the second connecting frame 3 are assembled. At the same time, when the pipe gallery body 1 is connected in pairs, sealing material can also be applied to its surface to enhance the sealing.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
