Description

Technical Field

[0001] This utility model relates to the field of integrated utility tunnel technology, and more specifically, to a hoisting device for a prefabricated utility tunnel. Background Technology

[0002] Integrated utility tunnels refer to underground tunnel spaces in cities that integrate various engineering pipelines such as electricity, communications, heating, and water supply. Above-ground attachments include installation ports and ventilation openings. They are vital infrastructure and "lifelines" for ensuring the operation of cities. Prefabricated utility tunnels do not require on-site casting; instead, they are transported directly to the site for hoisting after forming, thus greatly shortening the construction cycle.

[0003] After the precast pipe gallery has been manufactured and cured to the design strength, it can be hoisted by inserting steel wedge shafts into the pre-embedded sockets on the side wall of the precast pipe gallery. However, this method requires waiting for the precast pipe gallery to be cured to the design strength before it can be hoisted. As a result, the space of the precast pipe gallery production and pouring area needs to be occupied during the curing of the precast pipe gallery, which affects the subsequent production efficiency of the precast pipe gallery. Utility Model Content

[0004] In view of this, the present invention proposes a hoisting device for prefabricated pipe corridors, which aims to solve the problem that the existing technology requires waiting for the prefabricated pipe corridors to be cured to the design strength before they can be hoisted, which reduces the production efficiency of subsequent prefabricated pipe corridors.

[0005] This utility model proposes a hoisting device for prefabricated pipe racks, which includes: a support body and a base; wherein, the support body is used to support the prefabricated pipe rack; the base is located at the bottom of the support body, and the base is provided with multiple hoisting holes.

[0006] Furthermore, in the hoisting device for the prefabricated pipe gallery, the support body is a square ring structure. A first baffle is vertically installed on the inner ring of the support body, and a second baffle is vertically installed on the outer ring of the support body. The first baffle, the second baffle, and the support body form a ring-shaped receiving space, which is used to support the prefabricated pipe gallery.

[0007] Furthermore, the hoisting device for the prefabricated pipe gallery also includes: multiple fasteners; wherein each fastener is installed within the receiving space to fix the prefabricated pipe gallery relative to the support.

[0008] Furthermore, in the hoisting device for the precast pipe gallery, each fastener is a wooden wedge, and the wooden wedges are inserted at intervals between the precast pipe gallery and the first baffle and / or between the precast pipe gallery and the second baffle.

[0009] Furthermore, in the hoisting device for the precast pipe gallery, each fastener is a telescopic component, and each telescopic component is spaced apart between the precast pipe gallery and the first baffle and / or between the precast pipe gallery and the second baffle. Each telescopic component is used for its own expansion and contraction to secure the precast pipe gallery to the first baffle and the second baffle.

[0010] Furthermore, in the hoisting device for the aforementioned prefabricated pipe gallery, each telescopic component is a drive cylinder.

[0011] Furthermore, in the aforementioned hoisting device for the precast pipe gallery, each telescopic component includes: a double-ended screw and two threaded cylinders; wherein, the threads on the inner walls of the two threaded cylinders are in opposite directions, and the threads at the two ends of the double-ended screw are in opposite directions; the two ends of the double-ended screw are respectively screwed to the first ends of the two threaded cylinders in a one-to-one correspondence, and the second ends of the two threaded cylinders abut against the precast pipe gallery and the first baffle or the second baffle, respectively.

[0012] Furthermore, in the aforementioned hoisting device for the prefabricated pipe gallery, the base includes: two support bodies and four support columns; wherein, the two support bodies are vertically connected; the bottoms of the four support columns are respectively vertically set at the two ends of the two support bodies, and hoisting holes are opened at the top of the four support columns; the support body is set on the two support bodies.

[0013] Furthermore, in the hoisting device of the prefabricated pipe gallery, the support body is welded to the two supports; the two supports are also welded together.

[0014] Furthermore, in the hoisting device for the prefabricated pipe gallery, multiple inclined reinforcing ribs are provided between the two supports.

[0015] In this invention, the support body supports the precast pipe gallery, and the lifting holes on the base can be connected to a lifting device. This allows the lifting device to lift the precast pipe gallery by lifting the base, eliminating the need to wait for the concrete strength of the precast pipe gallery to reach its design strength before moving it to another location. This avoids occupying space in the precast pipe gallery's production and pouring area, facilitating the production of other precast pipe galleries and accelerating the production efficiency of precast pipe galleries. It solves the problem in existing technologies where waiting for the precast pipe gallery to cure to its design strength before lifting reduces the production efficiency of subsequent precast pipe galleries. Furthermore, since the lifting holes are located on the base, there is no need to pre-embed lifting sockets in the precast pipe gallery as in existing technologies, ensuring the structural strength of the precast pipe gallery and reducing the pre-embedded construction work during precast pipe gallery production. The lifting device is also reusable, improving its utilization rate. Attached Figure Description

[0020] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figures 1 to 3 The figure shows a preferred structure of the hoisting device for the precast pipe gallery in this embodiment. As shown, the hoisting device for the precast pipe gallery includes a support body 1 and a base 2. The support body 1 supports the precast pipe gallery 3. The base 2 is located at the bottom of the support body 1 and has multiple hoisting holes 21. The hoisting device is connected to each hoisting hole 21 via multiple steel wire ropes 8. The hoisting device lifts the base 2 and moves it, thereby moving the precast pipe gallery 3 to other positions.

[0022] In practice, side formwork 7 is installed on the support body 1, and the support body 1 and side formwork 7 form a casting template. Precast pipe gallery concrete is poured into the casting template. When the concrete reaches the removal strength of side formwork 7, side formwork 7 is removed. At this time, the concrete strength of the precast pipe gallery has not reached the design strength. The base 2 is hoisted by a lifting device using steel wire rope 8, thereby hoisting the precast pipe gallery 3 to other locations.

[0023] As can be seen, in this embodiment, the support body 1 supports the precast pipe gallery 3, and the lifting hole 21 on the base 2 can be connected to the lifting device. In this way, the lifting device can lift the precast pipe gallery 3 by lifting the base 2. There is no need to wait for the concrete strength of the precast pipe gallery to reach the design strength before the precast pipe gallery can be lifted to other locations, avoiding the occupation of the production and pouring area space of the precast pipe gallery. This facilitates the production of other precast pipe galleries and speeds up the production efficiency of the precast pipe gallery. It solves the problem in the prior art that the precast pipe gallery needs to be cured to the design strength before it can be lifted, which reduces the production efficiency of the subsequent precast pipe galleries. In addition, the lifting hole 21 is opened on the base 2, eliminating the need to pre-embed the lifting socket on the precast pipe gallery as in the prior art. This ensures the structural strength of the precast pipe gallery 3, reduces the pre-embedded construction content during the production of the precast pipe gallery 3, and the lifting device can be reused, improving the utilization rate.

[0024] See Figures 1 to 3 In the above embodiment, the support body 1 is a square ring structure. Specifically, the outer contour of the support body 1 is rectangular, and the interior of the support body 1 is hollow, making the support body 1 annular in shape. The shape of the support body 1 matches the cross-sectional shape of the prefabricated pipe gallery 3 to facilitate supporting the prefabricated pipe gallery 3.

[0025] A first baffle 4 is vertically arranged at the inner ring of the support body 1, and a second baffle 5 is vertically arranged at the outer ring of the support body 1. Specifically, since the support body 1 is annular, it has an inner annular edge and an outer annular edge. The first baffle 4 is annular, connected to the inner annular edge of the support body 1, and perpendicular to the support body 1. The first baffle 4 has a preset height, which can be determined according to actual conditions; this embodiment does not impose any restrictions on this. Correspondingly, the second baffle 5 is also annular, connected to the outer annular edge of the support body 1, and perpendicular to the support body 1. The second baffle 5 has a preset height, which can be determined according to actual conditions; this embodiment does not impose any restrictions on this.

[0026] The first baffle 4, the second baffle 5 and the support body 1 form an annular receiving space 6. The top of the receiving space 6 is open, the bottom wall of the receiving space 6 is the support body 1, and the receiving space 6 has opposite side walls, namely the first baffle 4 and the second baffle 5. The receiving space 6 is used to support the prefabricated pipe gallery 3.

[0027] As can be seen, in this embodiment, the support 1 has a simple structure and is easy to implement.

[0028] See Figures 1 to 3The hoisting device for the precast pipe gallery also includes multiple fasteners. Each fastener is installed within the receiving space 6 and is used to fix the precast pipe gallery 3 relative to the support body 1, so that the precast pipe gallery 3 is fixed within the receiving space 6, preventing the precast pipe gallery 3 from tilting or shaking during hoisting, and ensuring the stability of the precast pipe gallery 3 during hoisting.

[0029] One embodiment of each fastener is as follows: each fastener is a wooden wedge (not shown in the figure), and the wooden wedges are inserted at intervals between the precast pipe gallery 3 and the first baffle 4 and / or between the precast pipe gallery 3 and the second baffle 5. Specifically, multiple wooden wedges are inserted at intervals in the gap between the precast pipe gallery 3 and the first baffle 4, and multiple wooden wedges are inserted at intervals in the gap between the precast pipe gallery 3 and the second baffle 5. In specific implementation, the insertion position of each wooden wedge can be determined according to the actual situation. Multiple wooden wedges can be inserted only between the precast pipe gallery 3 and the first baffle 4, or only between the precast pipe gallery 3 and the second baffle 5, or multiple wooden wedges can be inserted between the precast pipe gallery 3 and the first baffle 4, and also between the precast pipe gallery 3 and the second baffle 5. This embodiment does not impose any restrictions on this. By inserting multiple wooden wedges into the gap between the precast pipe gallery 3 and the first baffle 4 or the second baffle 5, the precast pipe gallery 3 is squeezed relatively tightly with the first baffle 4 and the second baffle 5, ensuring that the precast pipe gallery 3 is stable and does not move on the support body 1, thus improving the stability of the precast pipe gallery 3.

[0030] Another implementation of each fastener is as follows: each fastener is a telescopic member (not shown in the figure), and each telescopic member is spaced apart between the precast pipe gallery 3 and the first baffle 4 and / or between the precast pipe gallery 3 and the second baffle 5. Each telescopic member is used for its own expansion and contraction to fasten the precast pipe gallery 3 to the first baffle 4 and the second baffle 5. Specifically, multiple telescopic members are spaced apart in the gap between the precast pipe gallery 3 and the first baffle 4, and multiple telescopic members are spaced apart in the gap between the precast pipe gallery 3 and the second baffle 5. In specific implementation, the placement of each telescopic member can be determined according to the actual situation. Multiple telescopic members can be placed only between the precast pipe gallery 3 and the first baffle 4, or only between the precast pipe gallery 3 and the second baffle 5, or multiple telescopic members can be placed between the precast pipe gallery 3 and the first baffle 4, and also between the precast pipe gallery 3 and the second baffle 5. This embodiment does not impose any restrictions on this. Each expansion joint extends to abut against the precast pipe gallery 3 and the first baffle 4 or the second baffle 5 at both ends. Thus, each expansion joint is positioned within the gap between the precast pipe gallery 3 and the first baffle 4 or the gap between the precast pipe gallery 3 and the second baffle 5, thereby tightly squeezing the precast pipe gallery 3 against the first baffle 4 and the second baffle 5 to ensure that the precast pipe gallery 3 remains fixed on the support body 1.

[0031] One embodiment of the structure of the telescopic component is as follows: each telescopic component can be a drive cylinder, which can be a hydraulic cylinder or a pneumatic cylinder. The extension and retraction of the drive cylinder causes the precast pipe gallery 3 to be tightly squeezed against the first baffle 4 and the second baffle 5.

[0032] Another embodiment of the telescopic component structure is as follows: each telescopic component includes a double-ended screw and two threaded cylinders. Each threaded cylinder has open ends, the threads on the inner walls of the two cylinders are in opposite directions, and the threads at the two ends of the double-ended screw are also in opposite directions.

[0033] The two ends of the double-ended screw correspond one-to-one with the first ends of two threaded cylinders, and each end of the double-ended screw is screwed into the corresponding threaded cylinder. The second ends of the two threaded cylinders abut against the precast pipe gallery 3 and the first baffle 4 or the second baffle 5, respectively. Specifically, when the expansion joint is located between the precast pipe gallery 3 and the first baffle 4, the second end of one threaded cylinder abuts against the precast pipe gallery 3, and the second end of the other threaded cylinder abuts against the first baffle 4. When the expansion joint is located between the precast pipe gallery 3 and the second baffle 5, the second end of one threaded cylinder abuts against the precast pipe gallery 3, and the second end of the other threaded cylinder abuts against the second baffle 5. By turning the middle part of the double-ended screw, the two threaded cylinders are simultaneously extended outward or retracted inward, thereby causing the two threaded cylinders to abut against the precast pipe gallery 3 and the first baffle 4 or the second baffle 5, respectively.

[0034] See Figures 1 to 3 In the above embodiments, the base 2 includes two support bodies 22 and four support columns 23. The two support bodies 22 are vertically intersecting and connected, and are located on the same plane, forming a cross-shaped structure. Preferably, the two support bodies 22 are welded together.

[0035] In practice, in order to ensure that the two supports 22 are on the same plane, the two supports 22 can share the connection part. That is, when connecting, the first support can be treated as a whole, and the second support can be divided into two parts. These two parts are placed symmetrically on the left and right sides of the middle part of the first support, and these two parts are welded perpendicularly to the middle part of the first support. After connecting, the two supports 22 form a cross-shaped structure.

[0036] Preferably, a plurality of inclined reinforcing ribs are provided between the two support bodies 22. Specifically, each reinforcing rib is inclined, each reinforcing rib is close to the connection part of the two support bodies 22, and the two ends of each reinforcing rib are respectively connected to the two support bodies 22.

[0037] The four support columns 23 correspond one-to-one with the two ends of the two support bodies 22. That is, each end of each support body 22 corresponds to one support column 23, and the bottom of each support column 23 is vertically disposed at the corresponding end of the corresponding support body 22. Each support column 23 is fixedly connected to the corresponding end of the corresponding support body 22, such as by welding. Alternatively, each support body 22 and the two support columns 23 at its two ends can be integrally formed. This embodiment does not impose any restrictions on this.

[0038] Each of the four support columns 23 has a lifting hole 21 at its top, and the lifting device is connected to each lifting hole 21 by a wire rope 8.

[0039] The support 1 is disposed on two supports 22. Specifically, if the two supports 22 are on the same plane, the support 1 is fixedly connected to the two supports 22, preferably by welding.

[0040] See Figures 1 to 3 The process of using the hoisting device for the precast pipe gallery is described as follows: During the fabrication of the precast pipe gallery 3 at the prefabrication yard, vertical formwork is used for concrete pouring. The formwork consists of side forms 7 and a support body 1. Concrete for the precast pipe gallery is poured into the formwork within the prefabrication yard. After the concrete pouring is completed and reaches the removal strength of the side forms 7, the side forms 7 are removed, but the support body 1 is not removed. Without waiting for the precast pipe gallery concrete to reach its design strength, and without affecting the structural quality of the precast pipe gallery 3, a crane is used with hooks and wire ropes 8 to lift the base 2, thereby lifting the precast pipe gallery 3. The precast pipe gallery 3 is then moved to a transport vehicle and transported to the construction site or to the precast pipe gallery curing area. This efficiently frees up space in the precast pipe gallery production and pouring area, creating construction space for subsequent precast pipe gallery production and accelerating production efficiency. When the precast pipe gallery 3 is to be flipped for installation, the hoisting device is dismantled and reused for the production of the next precast pipe gallery section.

[0041] In summary, in this embodiment, the support body 1 supports the precast pipe gallery 3, and the lifting hole 21 on the base 2 can be connected to the lifting device. In this way, the lifting device can lift the precast pipe gallery 3 by lifting the base 2 without waiting for the concrete strength of the precast pipe gallery to reach the design strength. Moreover, the precast pipe gallery can be lifted to other locations without removing the bottom formwork. This achieves rapid lifting and moving of the precast pipe gallery without affecting the structural strength of the precast pipe gallery, thereby freeing up construction space in the precast pipe gallery production site in a timely manner, shortening the time from production and curing of the precast pipe gallery in the precast plant to transportation to the construction site, and accelerating the production efficiency of the precast pipe gallery. Furthermore, the lifting hole 21 is opened on the base 2, eliminating the need to pre-embed lifting sockets on the precast pipe gallery as in the prior art, ensuring the structural strength of the precast pipe gallery 3, saving the process and engineering content of pre-embedding lifting sockets in the original precast pipe gallery, and the lifting device can be reused, improving the utilization rate.
