Technical Field

[0001] The present invention relates to the technical field of auxiliary tools for pipe gallery installation, and in particular to an anti-overturning device for the installation of an assembled prefabricated integrated pipe gallery at a large slope. Background Art

[0002] An urban underground pipeline corridor, also known as a "common trench" or "common pipeline," is an intensive tunnel constructed beneath a city, where two or more municipal pipelines, including electricity, communications, gas, heating, and water supply and drainage, are centrally laid. Urban underground pipelines are the lifeline of a city, and a pipeline corridor is a crucial element in ensuring the stability and safety of these pipelines and reducing subsequent maintenance costs. Pipe corridors, like arteries to the human body, are the lifeline of a city. However, the lack of fixtures to secure the pipelines during installation not only complicates construction but also slows down construction progress. They also suffer from poor stability, are prone to damage, and have a short service life.

[0003] The patent document with application number CN202022604494.8 discloses a fixing device for installing an underground pipe gallery, including a base, a pillar, a support plate and a fixing assembly. The base is provided with a placement slot and a groove. The placement slot is provided in the middle of the base, and the groove is symmetrically provided in two groups with the center line of the placement slot as the symmetry axis. The pillar is provided on the top wall of the base, and the pillar is symmetrically provided in two groups with the center line of the placement slot. The support plate is provided on the side wall of the pillar and close to the top, and the fixing assembly is provided on the base.

[0004] The above-mentioned fixing device for installing an underground pipe gallery can clamp and fix a pipe gallery in a horizontal state, but cannot stably fix a pipe gallery installed in an environment with a large slope. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an anti-overturning device for the installation of prefabricated integrated pipeline corridors on large slopes, so as to solve the problem in the prior art that pipeline corridors cannot be stably fixed when installed in an environment with large slopes.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: an anti-overturning device for large-slope installation of an assembled prefabricated integrated pipe gallery, comprising:

[0008] Support and limit assemblies, at least two of which are spaced apart along the length of the pipe gallery resting on the bottom plate, each support and limit assembly comprising:

[0009] A support rod, wherein the support rod freely passes through a first hook reserved on the pipe gallery;

[0010] The locking structure has two locking structures that are fixedly connected one to one to the two ends of the support rod and the slopes on both sides above the pipe gallery.

[0011] Working principle: first arrange the bottom pad on the large-slope installation position, and reserve multiple pairs of first hooks on the pipe gallery to facilitate lifting the pipe gallery to the bottom pad, and then connect each pair of first hooks and the slope of the large-slope installation position through a support limit assembly; specifically, the support rod passes through a pair of first hooks, and then the two ends of the support rod are fixedly connected to the slopes on both sides above the pipe gallery through a locking structure, thereby completing the limit fixation of the pipe gallery; then the pipe gallery can be installed. When the pipe gallery is installed, remove the connection between the locking structure and the support rod, and then move the support rod out of the first hook.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The anti-overturning device for the large-slope installation of this prefabricated integrated pipeline corridor is mainly composed of a bottom pad, a support rod in the support limit assembly, and a locking structure. It can stably fix the pipeline corridor limit on the large-slope installation position to ensure stable installation of the pipeline corridor and avoid the risk of slipping and overturning when the pipeline corridor is installed on a large slope.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below through specific embodiments:

[0019] like Figure 1 and Figure 2 As shown, the embodiment of the present invention proposes an anti-overturning device for large-slope installation of an assembled prefabricated integrated pipe gallery, comprising a bottom pad 1 and a support and limiting assembly;

[0020] Wherein, the bottom plate 1 is attached to the ground with a large slope;

[0021] There are at least two support and limit assemblies and they are spaced apart along the length direction of the pipe gallery 2 resting on the bottom plate 1. In this embodiment, the number of support and limit assemblies is two for explanation, and the number of support and limit assemblies can be adjusted according to needs.

[0022] Specifically, each support limit assembly includes a support rod 3 and a locking structure;

[0023] The support rod 3 freely passes through the first hook 4 reserved on the pipe gallery 2;

[0024] There are two locking structures, which are fixedly connected to the two ends of the support rod 3 and the slopes on both sides above the pipe gallery 2 in a one-to-one correspondence.

[0025] During construction: first arrange the bottom pad 1 on the installation position with a large slope, and the bottom pad 1 increases the friction of the pipe gallery 2 and reduces the sliding of the pipe gallery 2 on the installation position with a large slope; multiple pairs of first hooks 4 are reserved on the pipe gallery 2 to facilitate lifting the pipe gallery 2 onto the bottom pad 1, and then each pair of first hooks 4 and the slope of the installation position with a large slope are connected through a support limit assembly; specifically, the support rod 3 passes through a pair of first hooks 4, and then the two ends of the support rod 3 are fixedly connected to the slopes on both sides above the pipe gallery 2 through a locking structure, thereby completing the limit fixation of the pipe gallery 2; then the pipe gallery 2 can be installed. When the installation of the pipe gallery 2 is completed, the connection between the locking structure and the support rod 3 is removed, and then the support rod 3 is removed from the first hook 4.

[0026] The anti-overturning device for the large-slope installation of this prefabricated integrated pipeline corridor is mainly composed of a bottom pad 1, a support rod 3 in a support limit assembly, and a locking structure. It can stably limit and fix the pipeline corridor 2 at the large-slope installation position to ensure stable installation of the pipeline corridor 2 and avoid the risk of slipping and overturning when the pipeline corridor 2 is installed at a large slope.

[0027] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the anti-overturning device for the large-slope installation of an assembled prefabricated integrated pipe gallery, wherein each of the locking structures includes a sleeve 5 and a nut 6;

[0028] The sleeve 5 is embedded in the mounting hole drilled on the slope, and one end of the support rod 3 is embedded in the sleeve 5;

[0029] The nut 6 is threadedly connected to the support rod 3 and an anchor plate 7 embedded in the opening of the mounting hole is abutted between the nut 6 and the sleeve 5.

[0030] After the pipe gallery 2 is hoisted to the bottom plate 1 placed in the large-slope installation position, the two support rods 3 pass through the two pairs of first hooks 4, and then the drilling positions are marked on the slopes on both sides above the pipe gallery 2. The required installation holes are drilled with an electric drill, and then the sleeve 5 is inserted into the installation hole. Then, the anchor plate 7 is installed at the mouth of the installation hole, and then one end of the support rod 3 is passed through the hole on the anchor plate 7 and inserted into the sleeve 5. Finally, it is locked and fixed by the nut 6 connected to the support rod 3, thereby completing the limit fixation of the pipe gallery 2. At this time, the pipe gallery 2 can be installed stably. After the pipe gallery 2 is installed, the anti-overturning device of the prefabricated integrated pipe gallery with a large slope can be removed.

[0031] like Figure 2 and Figure 3 As shown, according to another embodiment of the present invention, the anti-overturning device for the large-slope installation of an assembled prefabricated integrated pipeline corridor, in order to further improve the stability of the pipeline corridor 2 during the installation process, also includes two telescopic clamping assemblies connected between the bottom plate 1 and at least one support rod 3. The two telescopic clamping assemblies are distributed on both sides of the pipeline corridor 2 to clamp and fix it, and the length along the height direction of the pipeline corridor 2 is also adjustable.

[0032] In this embodiment: the lengths of the two telescopic clamping assemblies are adjustable and can be reasonably adjusted according to the height of the stationary pipe gallery 2 to be connected between the bottom plate 1 and the support rod 3. At the same time, the two telescopic clamping assemblies clamp and fix the pipe gallery 2, so that the anti-overturning device of the prefabricated integrated pipe gallery with a large slope installation can fix the pipe gallery 2 more stably.

[0033] Specifically: Each of the telescopic clamping assemblies used includes a fixed cylinder 8, a movable rod 9, an adjustable locking portion and a clamping claw 10;

[0034] Wherein, one end of the fixing tube 8 is connected to the bottom plate 1;

[0035] One end of the movable rod 9 is slidably disposed in the fixed cylinder 8, and the other end is connected to the support rod 3 via a second hook 11;

[0036] The adjustable locking portion is connected between the fixed cylinder 8 and the movable rod 9 and is used to control the locking state between the fixed cylinder 8 and the movable rod 9;

[0037] The clamping jaw 10 is connected to an adjustable locking portion, and the adjustable locking portion controls the contact state between the clamping jaw 10 and the pipe gallery 2 .

[0038] During adjustment, the adjustable locking part is disengaged from the locking fixation between the fixed cylinder 8 and the movable rod 9. At this time, the adjustable locking part also disengages the clamping jaws 10 from the pipe gallery 2, so that relative movement can be generated between the fixed cylinder 8 and the movable rod 9, so that the second hook 11 is connected to the support rod 3. Later, the adjustable locking part is locked and fixed between the fixed cylinder 8 and the movable rod 9. At this time, the adjustable locking part also disengages the clamping jaws 10 from the pipe gallery 2, thereby further completing the limit fixation of the pipe gallery 2.

[0039] The adjustable locking portion used includes a support block 12, an adjustment sleeve 13, a locking portion and a mounting plate 14;

[0040] The support block 12 is fixedly sleeved on the outside of the fixed cylinder 8;

[0041] The adjusting sleeve 13 is slidably mounted between the fixed cylinder 8 and the outer side of the movable rod 9, and a return sleeve spring 15 movably mounted on the outer side of the fixed cylinder 8 is connected between the adjusting sleeve 13 and the supporting block 12;

[0042] The locking portion is disposed in the adjustment sleeve 13 and is locked and fixed with the moving rod 9;

[0043] The mounting plate 14 is connected to the support block 12, and the middle portion of the clamping jaw 10 is rotatably connected to the mounting plate 14 via a rotating member. One end of the clamping jaw 10 abuts against the adjustment sleeve 13, and the other end abuts against the pipe gallery 2.

[0044] The adjusting sleeve 13 is moved in a direction close to the supporting block 12 so that the locking portion is disengaged from locking the moving rod 9 and the clamping claw 10 is disengaged from abutting against the pipe gallery 2 .

[0045] During adjustment: the adjusting sleeve 13 is moved in the direction close to the supporting block 12, the return spring contracts, and the adjusting sleeve 13 drives the locking portion to disengage from the locking fixation on the moving rod 9; at this time, the movement of the adjusting sleeve 13 causes the clamping end of the clamping jaw 10 to rotate in the direction away from the pipe gallery 2 under the action of the rotating member, and the clamping jaw 10 is disengaged from the abutment with the pipe gallery 2; the moving rod 9 can be moved. After the moving rod 9 completes the movement, the adjusting sleeve 13 is released, the return spring resets to cause the adjusting sleeve 13 to move in the opposite direction to reset, and the adjusting sleeve 13 drives the locking portion to lock the moving rod 9 again. At this time, the adjusting sleeve 13 drives the end abutting against it to rotate during the movement process, and the clamping end of the clamping jaw 10 rotates in the direction close to the pipe gallery 2 to abut against the pipe gallery 2 again.

[0046] Based on the above solution, the locking portion in the present invention includes a clamp 16 and a traction structure;

[0047] There are multiple clamps 16, each of which is slidably disposed in the adjustment sleeve 13, and the multiple clamps 16 are circumferentially arranged outside the moving rod 9;

[0048] A traction structure is connected between each clamp 16 and the fixed tube 8. Each traction structure includes an elastic telescopic rod 17 fixedly connected between the clamp 16 and the inner wall of the adjustment sleeve 13 and a traction rope 18 connected between the elastic telescopic rod 17 and the fixed tube 8; the elastic telescopic rod 17 is extended and retracted by moving the adjustment tube through the traction rope 18.

[0049] In this embodiment: the number of clamps 16 and traction structures can be 3 or 4, etc., and each traction rope 18 is provided with a mounting groove on the inner wall of the adjusting sleeve 13, and two guide wheels 19 arranged along the moving direction of the adjusting sleeve 13 are rotatably provided in the mounting groove, and the middle part of the traction rope 18 is tensioned and connected to the two guide wheels 19; and the elastic telescopic rod 17 specifically includes a support tube that is rotatably fixed to the inner wall of the adjusting sleeve 13 and a movable rod with one end slidingly arranged in the support tube, the movable rod is connected to the inner wall of the support tube by at least one spring, and the other end of the movable rod is connected to the corresponding clamp 16; the middle part of the traction rope 18 is freely inserted into the support tube and connected to the movable rod.

[0050] During adjustment: move the adjusting sleeve 13 in the direction close to the support block 12, the reset spring contracts, and the adjusting sleeve 13 pulls the movable rod into the support tube through the traction of the traction rope 18, and the clamp 16 moves in the direction away from the movable rod 9, and the two guide wheels 19 pull the traction rope 18 to move stably for traction; the adjusting sleeve 13 uses multiple traction structures to make multiple clamps 16 move synchronously, and multiple clamps 16 all move in the direction away from the movable rod to disengage the locking fixation of the movable rod, so that the fixed tube 8 and the movable rod 9 can move relative to each other; release the adjusting sleeve 13, and the reset spring resets to make the adjusting sleeve 13 move in the opposite direction. At this time, the spring resets to make the movable rod 9 and the traction rope 18 move in the opposite direction, and then multiple clamps 16 move in the direction close to the movable rod 9 to lock and fix the movable rod 9 again.

[0051] Furthermore, an arrangement hole 20 is opened on the mounting plate 14, and the rotating part includes a rotating shaft rotatably arranged in the arrangement hole 20. The middle part of the clamping jaw 10 is arranged in the arrangement hole 20 and is connected to the rotating shaft. The arrangement hole 20 is also provided with a limit column 21 and a reset block 22 located on different sides of the clamping jaw 10. The reset block 22 slides against the clamping jaw 10 and the reset block 22 is connected to the inner wall of the arrangement hole 20 through a support spring.

[0052] Here: a limiting track can be set between the reset block 22 and the inner wall of the arrangement hole 20 to ensure the stable movement of the reset block 22; when the adjusting sleeve 13 is moved in the direction close to the support block 12, the end of the clamping jaw 10 that is against the adjusting sleeve 13 is acted upon by the supporting spring so that the end of the clamping jaw 10 that is matched with the adjusting sleeve 13 rotates in the direction close to the moving direction of the adjusting sleeve 13, and the other end of the clamping jaw 10 moves in the direction away from the pipe gallery 2 to disengage the pipe gallery 2, and the limiting column 21 limits the rotation of the clamping jaw 10 in this direction; when the adjusting sleeve 13 moves in the reverse direction, the clamping jaw 10 is driven to rotate in the reverse direction, and the clamping jaw 10 is again against the pipe gallery 2 to clamp and fix it. During this process, the reset block 22 moves in the reverse direction, and the supporting spring contracts to store force; the design of the reset block 22 makes the rotation of the clamping jaw 10 driven by the supporting spring more stable.

[0053] like Figure 1 As shown, according to another embodiment of the present invention, an anti-overturning device for installing an assembled prefabricated integrated pipeline corridor at a large slope, wherein the lower end of the bottom pad 1 is connected to a limit block 23 that is against one end of the pipeline corridor 2; the bottom pad 1 and the limit block 23 form an "L" shape, so that the pipeline corridor 2 is more stable when it is stationary on the bottom pad 1.

[0054] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, an anti-overturning device for the installation of an assembled prefabricated integrated pipeline corridor with a large slope, wherein the structures of the first hook 4 and the second hook 11 can be the same, both are existing structures, and both can include a hook body connected to the pipeline corridor 2 or the movable rod 9 and a clip that is rotatably connected at the opening of the hook body, so as to quickly connect the first hook 4 and the second hook 11 to the support rod 3.
