Description

Technical Field

[0001] The present invention relates to the technical field of integrated pipe corridors, and in particular to a hoisting device, a hoisting device and a method for hoisting a pipe corridor. Background Art

[0002] The integrated pipe gallery refers to a tunnel space built underground in the city, integrating various engineering pipelines such as electricity, communications, heat, and water supply. The above-ground attachments are facilities such as outlets and vents. It is an important infrastructure and "lifeline" to ensure the operation of the city. The prefabricated pipe gallery does not need to be cast on site, but is directly transported to the site for hoisting after forming, which greatly shortens the construction period.

[0003] Large-section prefabricated pipe gallery sections are difficult to transport due to their large cross-sections. Usually, the cross-section of the prefabricated pipe gallery section is decomposed into two halves for prefabrication, and then transported to the construction site for splicing into a complete whole-section prefabricated pipe gallery section. However, both the half-piece prefabricated pipe gallery section and the final assembled whole-section prefabricated pipe gallery section need to be equipped with separate hoists for hoisting. These two types of hoists are unrelated to each other, resulting in a large number of hoists and increased construction costs. In addition, the whole-section prefabricated pipe gallery section needs to be flipped from the flat position during stacking to the upright position during construction. The flipping process needs to be implemented using a customized flip stand, which increases construction costs. Summary of the invention

[0004] In view of this, the present invention proposes a hoisting device, which aims to solve the problem of large number of hoists and high construction cost when hoisting a prefabricated pipe gallery in the prior art. The present invention also proposes a hoisting device having the hoisting device and a method for hoisting a pipe gallery using the hoisting device.

[0005] In one aspect, the present invention provides a sling, which includes: a first hoisting body, two second hoisting bodies, two supporting bodies, two first lifting rings and a second lifting ring; wherein the two supporting bodies are arranged side by side and spaced by a preset distance, and the first ends of the two supporting bodies are vertically arranged on the first hoisting body; the two second hoisting bodies are respectively placed on both sides of the two supporting bodies, each of the second hoisting bodies is inclined and its two ends are respectively connected to the corresponding end of the first hoisting body and the second end of the corresponding supporting body; the two first lifting rings are respectively arranged at the two ends of the first hoisting body; the second lifting ring is arranged between the second ends of the two supporting bodies.

[0006] Furthermore, in the above-mentioned sling, the two support bodies are placed in the middle of the first sling body and are symmetrically arranged with respect to the center line of the first sling body in the width direction; and the two second sling bodies are symmetrically arranged with respect to the center line of the first sling body in the width direction.

[0007] Furthermore, in the above-mentioned lifting device, the length of the first lifting body is greater than the height of half a pipe gallery section; the sum of the width of the first lifting body and the length of the supporting body is greater than the width of half a pipe gallery section.

[0008] In the present invention, the two second hoisting bodies are respectively placed on both sides of the two supporting bodies and form a triangular structure with the first hoisting body, which improves the stability of the sling. The two supporting bodies are vertically arranged on the first hoisting body as two stiffening ribs, which can improve the strength of the sling. The gap between the two supporting bodies is used to pass the steel wire rope when the pipe gallery is subsequently flipped, which is convenient for flipping the pipe gallery. The two first lifting rings on the first hoisting body and the second lifting ring between the two supporting bodies can be used to hoist a half-piece pipe gallery section. When hoisting the entire pipe gallery, it is only necessary to closely connect the first hoisting bodies of the two hoists, without the need to equip a separate hoist, thereby reducing the number of hoists and saving construction costs. Moreover, after closely connecting the first hoisting bodies of the two hoists, the pipe gallery can be flipped, without the need to customize a flip stand, thereby reducing construction costs. The sling can be used to realize the lifting of a half-piece pipe gallery section, the lifting and flipping of the pipe gallery, thereby solving the problem of a large number of hoists and high construction costs when lifting prefabricated pipe galleries in the prior art. Moreover, the sling is simple to manufacture, flexible to operate, and easy to implement.

[0009] On the other hand, the present invention further proposes a lifting device, which comprises: two lifting devices of any one of the above-mentioned types; wherein the first lifting bodies in the two lifting devices are closely and detachably connected.

[0010] Furthermore, in the above-mentioned lifting device, the first lifting bodies in the two lifting devices are connected by a plurality of bolts.

[0011] Since the sling has the above-mentioned effects, the lifting device having the sling also has corresponding technical effects.

[0012] On the other hand, the present invention also proposes a method for hoisting a pipe gallery using any of the above-mentioned hoists, the method comprising the following steps: a first hoisting step, hoisting two half-piece pipe gallery sections from a prefabrication yard to a storage yard respectively using a hoist; an assembling step, assembling the two half-piece pipe gallery sections into a pipe gallery; a second hoisting step, connecting the first hoisting bodies in the two hoists to form a hoisting device, and hoisting the pipe gallery to a construction site using the hoisting device; and a flipping step, flipping the pipe gallery using the hoisting device.

[0014] Furthermore, in the above-mentioned method for hoisting the pipe gallery, in the first hoisting step, the two first lifting rings in the lifting device are respectively connected to the two connecting shafts of the half-piece pipe gallery section through steel wire ropes, and the second lifting ring in the lifting device is connected to the screw rod of the half-piece pipe gallery section through steel wire ropes; the crane is respectively connected to the two first lifting rings and the second lifting rings through three steel wire ropes to lift the half-piece pipe gallery section.

[0015] Furthermore, in the above-mentioned method for hoisting the pipeline corridor, in the second hoisting step, two first lifting rings in one of the lifting devices are respectively connected to two connecting shafts on the half-piece pipeline corridor sections at corresponding positions in the pipeline corridor through steel wire ropes, and the two first lifting rings are respectively connected to the crane through steel wire ropes; the second lifting rings in the two lifting devices are respectively connected to the screw rods on the two half-piece pipeline corridor sections in the pipeline corridor through steel wire ropes, and the two second lifting rings are respectively connected to the crane through steel wire ropes.

[0016] Furthermore, in the above-mentioned method for hoisting the pipeline corridor, in the flipping step, two first lifting rings in one of the lifting devices are respectively connected to two connecting shafts on the half-pipe corridor section at corresponding positions in the pipeline corridor through steel wire ropes, and the two first lifting rings are respectively connected to the main hook of the crane through steel wire ropes; the auxiliary hook of the crane is connected to the auxiliary steel wire rope, and the auxiliary steel wire rope is passed between two supporting bodies in one of the lifting devices and connected to the screw on the corresponding half-pipe corridor section; the auxiliary steel wire rope is tightened by the auxiliary hook to flip the pipeline corridor.

[0017] In the present invention, a hoist is used to hoist a half-section of the pipeline corridor from the prefabrication yard to the stacking yard, and the first hoisting bodies in the two hoists are connected to form a hoisting device. The hoisting device can be used to hoist the entire pipeline corridor from the stacking yard to the construction site.

[0028] Spreader Example:

[0029] See also Figure 1 , Figure 1 A schematic diagram of the structure of a sling provided in an embodiment of the present invention. As shown in the figure, the sling includes: a first sling body 1, two second sling bodies 2, two support bodies 3, two first lifting rings 4 and second lifting rings 5. Among them, the first sling body 1 is in the shape of an elongated strip. The two support bodies 3 are arranged in parallel, and the two support bodies 3 are spaced apart by a preset distance, which can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. In this embodiment, the two support bodies 3 are spaced apart by 100 mm.

[0030] The first ends of the two support bodies 3 ( Figure 1 The two supports 3 are arranged vertically on the first hanging body 1. Specifically, the two supports 3 are placed on the same side of the first hanging body 1. The two supports 3 are perpendicular to the first hanging body 1. That is, the length direction of each support 3 ( Figure 1The direction from left to right as shown) and the length direction of the first sling body 1 ( Figure 1 The a direction shown in the figure is perpendicular to each support body 3, and each support body 3 is along the width direction ( Figure 1 Preferably, the two support bodies 3 are placed in the middle of the first hanging body 1, and the two support bodies 3 are symmetrically arranged with respect to the center line of the first hanging body 1 in the width direction.

[0031] The two second sling bodies 2 and the two supporting bodies 3 are placed on the same side of the first sling body 1, and the two second sling bodies 2 are placed on both sides of the two supporting bodies 3, and each second sling body 2 is arranged obliquely.

The sum of the width of the first hoisting body 1 and the length of the support body 3 is greater than the width of the half-piece pipe gallery section 6 (where the width direction of the half-piece pipe gallery section 6 is Figure 2 d direction as shown), that is, the overall width of the sling is greater than the width of half of the pipe gallery section 6. Preferably, the overall width of the sling is greater than the width of half of the pipe gallery section 6 by 200 mm.

[0035] The overall length of the sling is greater than twice the overall width of the sling, wherein the overall length of the sling=the length of the first sling body 1 , and the overall width of the sling=the width of the first sling body 1 +the length of the support body 3 .

[0036] During specific implementation, the first hoisting body 1, the second hoisting body 2 and the supporting body 3 are all made of steel sections.

[0037] See also Figure 2 The hoisting device hoists the half-piece pipe gallery section 6, and the cross section of the half-piece pipe gallery section 6 is U-shaped, that is, the half-piece pipe gallery section 6 includes: two opposite side walls and a connecting wall. The two side walls are parallel and spaced a certain distance apart, and the two ends of the connecting wall are respectively connected to the ends of the corresponding ends of the two side walls, that is, the connecting wall is sandwiched between the two side walls, and the two side walls and the connecting wall form a U shape. A plug hole 61 is provided on the outside of each side wall, and a connecting shaft 7 is inserted in the plug hole 61. A threaded hole 62 is provided on the outer wall of the connecting wall, and the threaded hole 62 is screwed to the screw 8.

[0038] See also Figure 6 When the half-piece pipe gallery section 6 is hoisted by the hoist, the first hoisting rings 4 at the two ends of the first hoisting body 1 correspond to the connecting shafts 7 on the two side walls of the half-piece pipe gallery section 6, and the second hoisting rings 5 ​​between the two supporting bodies 3 correspond to the screws 8 on the connecting wall of the half-piece pipe gallery section 6. Each first hoisting ring 4 is connected to the corresponding connecting shaft 7 in the half-piece pipe gallery section 6 by a steel wire rope 10, and the second hoisting ring 5 is also connected to the screw 8 by a steel wire rope 10. The crane is connected to the two first hoisting rings 4 and the second hoisting rings 5 ​​by three steel wire ropes 10, and the half-piece pipe gallery section 6 is hoisted by the crane.

[0039] See also Figure 5 and Figure 7 When the two half-piece pipe gallery sections 6 are butt-joined to form an integral pipe gallery 9, the two hoists are connected, that is, the first hoisting bodies 1 in the two hoists are connected to form a hoisting device. The two half-piece pipe gallery sections 6 correspond to the two hoists up and down, respectively. The two half-piece pipe gallery sections 6 can be respectively recorded as the left half-piece pipe gallery section and the right half-piece pipe gallery section, and the two hoists are respectively recorded as the left hoist and the right hoist. The left half-piece pipe gallery section corresponds to the left hoist, and the right half-piece pipe gallery section corresponds to the right hoist. Using four steel wire ropes 10, the two first hoisting rings 4 in the left hoist are respectively connected to the two connecting shafts 7 on the left half-piece pipe gallery section through two steel wire ropes 10, and the two second hoisting rings 5 ​​in the two hoisting rings are respectively connected to the screws 8 on the two half-piece pipe gallery sections through two steel wire ropes 10. The crane is connected to the two second hoisting rings 5 ​​in the hoisting device and the two first hoisting rings 4 in the left hoist through four steel wire ropes 10, and the integral pipe gallery 9 is hoisted by the crane.

[0040] See also Figure 5 and Figure 8When the whole pipe gallery 9 is turned over, the two first lifting rings 4 in the right sling are respectively connected to the two connecting shafts 7 on the right half pipe gallery section through two steel wires 10, the main hook 11 of the crane is connected to the two first lifting rings 4 in the right sling through the two steel wires 10, and the auxiliary hook 12 of the crane passes through the gap between the two supporting bodies 3 in the left sling through an auxiliary steel wire 13 and then connects to the screw 8 on the left half pipe gallery section. When turning over, the auxiliary hook 12 tightens the auxiliary steel wire 13 to turn over the whole pipe gallery 9 from a lying position to an upright position.

[0041] During specific implementation, the positions of the two first lifting rings 4 and the second lifting ring 5 can be set according to actual needs in order to facilitate connection with the crane through the steel wire rope and to connect with the half-piece pipe gallery section through the steel wire rope at the same time, so that the positions of the two first lifting rings 4 and the second lifting ring 5 can adapt to the connection with the crane and the half-piece pipe gallery section. Of course, the two first lifting rings 4 and the second lifting ring 5 can also be set in groups, that is, there are four first lifting rings 4 and two second lifting rings 5 ​​in total, wherein the two first lifting rings 4 are respectively arranged at the two ends of the top surface of the first lifting body 1, and the two first lifting rings 4 are respectively connected to the crane through the steel wire rope. The other two first lifting rings 4 are respectively arranged at the two ends of the bottom surface of the first lifting body 1, and the two first lifting rings 4 are respectively connected to the half-piece pipe gallery section through the steel wire rope. One of the second lifting rings 5 ​​is arranged between the top surfaces of the second ends of the two support bodies 3, and the second lifting ring 5 is connected to the crane through the steel wire rope. Another second lifting ring 5 is arranged between the bottom surfaces of the second ends of the two supporting bodies 3, and the second lifting ring 5 is connected to the half-piece pipe gallery section through a steel wire rope. As long as the stability between the lifting device and the crane, and between the lifting device and the half-piece pipe gallery section can be ensured and the lifting is convenient, this embodiment does not impose any restrictions on this.

[0042] It can be seen that in this embodiment, the two second hoisting bodies 2 are respectively placed on both sides of the two supporting bodies 3 and form a triangular structure with the first hoisting body 1, which improves the stability of the sling. The two supporting bodies 3 are vertically arranged on the first hoisting body 1 as two stiffening ribs, which can improve the strength of the sling. The gap between the two supporting bodies 3 is used for passing the wire rope when the pipe gallery is subsequently flipped, which facilitates the flipping of the pipe gallery. The two first lifting rings 4 on the first hoisting body 1 and the second lifting ring 5 between the two supporting bodies 3 can be used to lift the half-piece pipe gallery section 6. When the entire pipe gallery 9 is lifted, only It is only necessary to closely connect the first hoisting bodies 1 of the two hoists, without the need for separate hoists, thus reducing the number of hoists and saving construction costs; furthermore, after closely connecting the first hoisting bodies 1 of the two hoists, the corridor 9 can be flipped over, without the need for customized flipping frames, thus reducing construction costs; the hoisting device can be used to lift half of the corridor section 6, lift and flip the corridor 9, thus solving the problem of a large number of hoists and high construction costs in lifting prefabricated corridors in the prior art; furthermore, the hoisting device is simple to manufacture, flexible to operate, and easy to implement.

[0043] Lifting device embodiment:

[0044] This embodiment also proposes a lifting device, see Figure 3 The hoisting device comprises: two hoisting devices of any one of the above, wherein the first hoisting bodies 1 in the two hoisting devices are closely attached to each other and detachably connected, and preferably, the first hoisting bodies 1 in the two hoisting devices are connected by a plurality of bolts 14.

[0045] Among them, the specific implementation process of the lifting device can refer to the above description, and this embodiment will not be repeated here.

[0046] Since the sling has the above-mentioned effects, the lifting device having the sling also has corresponding technical effects.

[0047] Method embodiment of hoisting pipe gallery:

[0048] This embodiment also proposes a method for hoisting a pipe gallery using the above hoisting device, see Figure 4 The method for hoisting the pipe gallery comprises the following steps:

[0049] In the first lifting step S1, two half-pieces of the pipe gallery are lifted from the prefabrication yard to the storage yard by using a lifting device.

[0050] Specifically, the specific implementation process of the sling can refer to the above description, and this embodiment will not be repeated here.

[0051] The two half-pieces of the pipe gallery section can be lifted and transported from the prefabrication yard to the stacking yard in two times using a hoist, or the two half-pieces of the pipe gallery section can be lifted and transported from the prefabrication yard to the stacking yard using two hoists respectively, and this embodiment does not impose any limitation on this.

[0052] See also Figure 1 and Figure 2 The cross section of each half-piece pipe gallery section 6 is U-shaped, and each half-piece pipe gallery section 6 includes: two opposite side walls and a connecting wall. The two side walls are parallel and spaced a certain distance apart, and the two ends of the connecting wall are respectively connected to the ends of the corresponding ends of the two side walls, that is, the connecting wall is sandwiched between the two side walls, and the two side walls and the connecting wall form a U shape.

[0053] The outer walls of the two opposite side walls of each half-piece pipe gallery section 6 are provided with plug holes 61, and a connecting shaft 7 is inserted in each plug hole 61. A part of each connecting shaft 7 is inserted in the corresponding plug hole 61, and the other part is exposed outside the half-piece pipe gallery section 6 to serve as a hanging point. The outer wall of the connecting wall of each half-piece pipe gallery section 6 sandwiched between the two side walls is provided with a threaded hole 62, and a screw 8 is threaded in the threaded hole 62, and a part of the screw 8 is placed in the threaded hole 62, and a part of the screw 8 is exposed outside the half-piece pipe gallery section 6 to serve as a hanging point.

[0054] During specific implementation, the hole depth of each plug hole 61 and the hole depth of the threaded hole 62 are both less than or equal to 2 / 3 of the wall thickness of the half-piece pipe gallery section 6 .

[0055] See also Figure 6 During hoisting, the two first hoisting rings 4 in the hoist are respectively connected to the two connecting shafts 7 on the half-piece pipe gallery section 6 through the steel wire ropes 10, that is, there are two steel wire ropes 10, and each first hoisting ring 4 is connected to the corresponding connecting shaft 7 on the half-piece pipe gallery section 6 through a steel wire rope 10. The second hoisting ring 5 in the hoist is connected to the screw rod 8 of the half-piece pipe gallery section 6 through the steel wire rope 10. The crane is respectively connected to the two first hoisting rings 4 and one second hoisting ring 5 through three steel wire ropes 10, and the half-piece pipe gallery section 6 is hoisted by the crane.

[0056] In the assembly step S2, two half-piece pipe gallery sections are assembled into a pipe gallery.

[0057] Specifically, see Figure 5 , the two half-pieces of the pipe gallery section 6 are assembled in the stacking yard to form an integral pipe gallery 9.

[0058] In the second lifting step S3, the first lifting bodies in the two lifting devices are connected to form a lifting device, and the pipe gallery is lifted to the construction site by using the lifting device.

[0059] Specifically, see Figure 1 and Figure 3 , the first hoisting bodies 1 in the two hoisting devices are attached to each other and connected by bolts 14, so that the two hoisting devices are connected into a whole, that is, a hoisting device is formed.

[0060] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 , the two first lifting rings 4 in one of the slings are respectively connected to the two connecting shafts 7 on the half-piece pipe gallery section 6 at the corresponding position in the pipe gallery 9 through the steel wire rope 10, and the two first lifting rings 4 are respectively connected to the crane through the steel wire rope 10. Specifically, the two slings correspond one-to-one to the two half-piece pipe gallery sections 6 in the pipe gallery 9, and the two half-piece pipe gallery sections 6 can be respectively recorded as the left half-piece pipe gallery section and the right half-piece pipe gallery section, and the two slings are respectively recorded as the left sling and the right sling. The left half-piece pipe gallery section corresponds to the left sling, and the right half-piece pipe gallery section corresponds to the right sling. Select one of the slings, for example, select the left sling, and connect the two first lifting rings 4 in the left sling to the two connecting shafts 7 on the left half-piece pipe gallery section through the two steel wire ropes 10, and the two first lifting rings 4 are also respectively connected to the crane through the two steel wire ropes 10.

[0061] The second lifting rings 5 ​​in the two lifting devices are respectively connected to the screw rods 8 on the two half-piece pipe gallery sections 6 in the pipe gallery 9 through steel wire ropes 10, and the two second lifting rings 5 ​​are respectively connected to the crane through steel wire ropes 10. Specifically, each second lifting ring 5 is connected to the screw rod 8 on the corresponding half-piece pipe gallery section 6 through a steel wire rope 10, and each second lifting ring 5 is connected to the crane through a steel wire rope 10. In this way, the crane controls four steel wire ropes 10 to lift the entire pipe gallery 9 through the lifting device.

[0062] In the flipping step S4, the pipe gallery is flipped using a hoisting device.

[0063] Specifically, see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 , the two first lifting rings 4 in one of the slings are respectively connected to the two connecting shafts 7 on the half-piece pipe gallery section 6 at the corresponding position in the pipe gallery 9 through the steel wire ropes 10, and the two first lifting rings 4 are respectively connected to the main hook 11 of the crane through the steel wire ropes 10. More specifically, one of the slings is selected, for example, the right sling is selected, the two first lifting rings 4 in the right sling are respectively connected to the two connecting shafts 7 on the right half-piece pipe gallery section through the two steel wire ropes 10, and the main hook 11 of the crane is connected to the two first lifting rings 4 in the right sling through the two steel wire ropes 10 in a one-to-one correspondence, so that the two connecting shafts 7 on the right half-piece pipe gallery section suspended by the main hook 11 of the crane serve as the main bearing points.

[0064] The auxiliary hook 12 of the crane is connected to the auxiliary steel wire rope 13, and the auxiliary steel wire rope 13 is passed through the two supporting bodies 3 in one of the hoisting devices and connected to the screw 8 on the corresponding half-piece corridor section 6. Specifically, after the auxiliary steel wire rope 13 can pass through the gap between the two supporting bodies 3 in the left hoisting device, the auxiliary steel wire rope 13 is connected to the screw 8 on the left half-piece corridor section. At this time, the screw 8 on the right half-piece corridor section is not connected to the right hoisting device, nor is it connected to the auxiliary hook 12, that is, the screw 8 on the right half-piece corridor section is in an idle state. The screw 8 on the left half-piece corridor section suspended by the auxiliary hook 12 of the crane serves as a flipping auxiliary point to assist in force bearing, ensure the stability of the corridor 9 hoisting plane and the force point when flipping, thereby realizing the safety and stability of the three-point hoisting corridor 9.

[0065] During the overturning, the auxiliary wire rope 13 is tightened by the auxiliary hook 12 to overturn the pipe gallery 9, so that the pipe gallery 9 is overturned from a lying state to an upright state.

[0066] It can be seen that in the present embodiment, a hoist is used to hoist half of the tunnel section from the prefabrication yard to the stacking yard, and the first hoisting bodies in the two hoists are connected to form a hoisting device, and the hoisting device can be used to hoist the entire tunnel from the stacking yard to the construction site. At the construction site, the hoisting device and the main hook and auxiliary hook of the crane are used to flip the entire tunnel, thereby realizing the lifting of half of the tunnel section by one hoist, the lifting and flipping of the tunnel. The operation is simple and easy to implement, which improves the construction efficiency. There is no need to equip multiple sets of hoists or customize flipping frames, thereby saving construction costs.
