Description

Technical Field

[0001] The invention relates to the technical field of hanging cranes, and in particular to a hanging device for a water pipe section used in a highly efficient pipe jacking construction. Background Art

[0002] Pipe jacking is a pipeline burial construction technology that does not involve excavation or requires minimal excavation. In the working pit, the friction between the pipeline and the surrounding soil is overcome by the jacking force generated by the jacking equipment, and the water pipe is pushed into the soil according to the designed slope. The pipe sections of the pipe jacking are generally cast and manufactured in the prefabrication plant, then transported to the pipe jacking construction site by a transport vehicle, and finally hoisted into the foundation pit by a hoisting crane.

[0003] In the prior art, a hanging lifting device is generally used, and the cable of the hanging lifting device has two hooks. A hole is opened on the pipe section and a lifting lug is installed. The two hooks hook the lifting lug of the pipe section to lift the pipe section. Opening a hole on the pipe section will affect the overall strength of the pipe section, and after the pipe section is hoisted into place, the lifting lug needs to be removed, and then the hole needs to be sealed. The operation is very troublesome and greatly affects the progress of the construction. Sometimes, ropes are used to tie the pipe section, and then the ropes are hooked with hooks, but after the pipe section is hoisted into place, the ropes still need to be removed, which also takes a certain amount of time, which also affects the progress of the construction.

[0004] Therefore, the prior art needs to be improved. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the drilling of holes for installing lifting ears in the prior art affects the strength of the pipe joint, the lifting time is long, and the construction progress is affected. The purpose is to provide an efficient hanging device for water pipe joints used in jacking construction, which adopts the corresponding technical scheme and has the beneficial effects of not affecting the strength of the pipe joint, convenient installation and disassembly, short lifting time and improved construction efficiency.

[0006] The present invention is achieved through the following technical solutions:

[0007] An efficient hanging device for water pipe sections used in pipe jacking construction, comprising a lifting gantry, an electric hoist, a rotating mechanism and a fixing mechanism.

[0008] The lifting gantry is installed at the pipe jacking construction site, one side below the lifting gantry is set as a pipe segment stacking platform, and the other side below the lifting gantry is set as a construction foundation pit.

[0009] A moving track is arranged on the top of the lifting gantry, and the electric hoist is installed on the moving track and moves along the moving track.

[0010] The electric hoist is provided with a suspension rope, and the suspension rope is connected to the rotating mechanism. The rotating mechanism is provided with a connecting rope, and the connecting rope is connected to the fixing mechanism.

[0011] The fixing mechanism includes a limit rod, and a support member extending out of the pipe joint is provided at the upper part of the limit rod. The connecting rope passes around the support member and is connected to the lower part of the limit rod. When hanging, the inclined upper end of the limit rod is close to the side of the pipe joint port, and the support member applies a thrust to the limit rod, and the connecting rope applies a pulling force to the limit rod. The thrust and pulling force work together to clamp the upper and lower ends of the limit rod at the top and bottom of the pipe joint respectively.

[0012] In the above technical solution, the pipe segments can be fixed and connected without installing lifting ears or binding ropes, which greatly saves the lifting time. Before hanging, the electric hoist is first moved to the pipe segment stacking platform, and then the lifting rope is lowered. The operator places the fixing mechanism inside the two sides of the pipe segment. The limit rod is in an inclined state and the top of the limit rod is closer to the pipe mouth side of the pipe segment. The connecting rope of the rotating mechanism is connected to the lower part of the limit rod, and then the connecting rope passes through the support. During hanging, the connecting rope pulls the bottom end of the limit rod outward and upward, and the connecting rope pushes the top end of the limit rod inward through the support. The thrust and pull work together to clamp the upper and lower ends of the limit rod to the top and bottom of the pipe segment respectively, so as to achieve a fixed connection of the pipe segment.

[0013] Furthermore, in the present invention, an arc-shaped anti-slip part is provided at the end of the above-mentioned limit rod, and an anti-slip rubber layer is provided on the surface of the anti-slip part.

[0014] Furthermore, in the present invention, the above-mentioned limiting rod is provided with a reinforcing rod connected to the anti-slip member.

[0015] Furthermore, in the present invention, the anti-slip member is configured as an arc-shaped cylinder.

[0016] Furthermore, in the present invention, the above-mentioned rotating mechanism includes a base connected to the suspension rope, a rotating shaft is arranged at the center of the base, the rotating shaft is provided with a rotating disk rotatably connected to the top of the base, the bottom of the rotating shaft is connected to the connecting rope, and the base is provided with a driver for driving the rotating shaft to rotate.

[0017] Furthermore, in the present invention, a bearing for supporting the rotating disk is disposed on the top of the base.

[0018] Furthermore, in the present invention, the driver is configured as a motor, the driver is connected to a reducer, a pulley 1 is provided on the top of the rotating shaft, and the reducer is provided with a pulley 2 which is transmission-connected to the pulley 1.

[0019] Furthermore, in the present invention, the two drivers and the two reducers are symmetrically arranged.

[0020] Furthermore, in the present invention, the suspension rope is connected to at least four evenly spaced secondary chains, and the secondary chains are connected to the base.

[0021] Furthermore, in the present invention, a sheave or a clamp is provided at the end of the support member, and the connecting rope is connected to the sheave or the clamp.

[0022] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0023] Improve efficiency: before hanging, the electric hoist is first moved to the pipe segment stacking platform, and then the lifting rope is lowered. The operator places the fixing mechanism inside the two sides of the pipe segment. The limit rod is in an inclined state and the top of the limit rod is closer to the pipe mouth side of the pipe segment. The connecting rope of the rotating mechanism is connected to the lower part of the limit rod, and then the connecting rope passes through the support. During hanging, the connecting rope pulls the bottom end of the limit rod outward and upward, and the connecting rope pushes the top of the limit rod inward through the support. The thrust and tension work together to clamp the upper and lower ends of the limit rod at the top and bottom of the pipe segment respectively, so as to achieve a fixed connection of the pipe segment. After the pipe segment is hoisted into place, the fixing mechanism can be manually removed. Compared with the disassembly of the lifting ears and the untying of the ropes in the prior art, it takes less time and is more convenient to install and disassemble. Therefore, the efficient hanging device for water pipe segments for jacking construction of the present invention has a higher hanging and installation efficiency and does not affect the progress of jacking construction.

[0024] Ensure the strength of the pipe joint: the fixing mechanism directly abuts against the inner wall of the pipe joint, and there is no need to drill holes in the pipe joint to install lifting ears, so it will not affect the overall strength of the pipe joint and extend the service life of the pipe joint.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] Example, combined with Figures 1 to 5 As shown, a highly efficient hanging device for water pipe sections for pipe jacking construction according to an embodiment of the present invention is shown, and the specific structure and principle are described as follows.

[0035] like Figure 1 and Figure 2As shown, the hanging equipment of the efficient water pipe segment for jacking construction in this embodiment mainly includes four parts: a lifting gantry 1, an electric hoist 2, a rotating mechanism 3 and a fixing mechanism 4. The lifting gantry 1 is used to provide an installation position and a moving path for the electric hoist 2, the electric hoist 2 is used to lift and lower the pipe segment 7 and drive the pipe segment 7 to move, the rotating mechanism 3 is used to drive the pipe segment 7 to rotate horizontally and adjust the installation direction of the pipe segment 7, and the fixing mechanism 4 is used to connect with the pipe segment 7.

[0036] Combination Figure 1 As shown, in some implementations of this embodiment, the lifting gantry 1 can adopt the gantry in the prior art, and the four supports of the lifting gantry 1 are installed on the ground of the jacking pipe construction site, and can be fixed by piling to prevent the lifting gantry 1 from moving or collapsing. The pipe segment stacking platform 5 is located on the left side below the lifting gantry 1, and the construction pit 6 is located on the right side below the lifting gantry 1. The moving track 101 is fixedly installed on the top of the lifting gantry 1. The moving track 101 serves as the moving path of the electric hoist 2, which facilitates the electric hoist 2 to move back and forth from the pipe segment stacking platform 5 and the construction pit 6.

[0037] Furthermore, the electric hoist 2 adopts the 20-ton lifting weight electric hoist 2 in the prior art, and the pipe section 7 with an inner diameter of about 1.8 meters, an outer diameter of about 2.2 meters, and a length of about 2 meters is a commonly used specification at present. The weight of the pipe section 7 is about 10.6 tons. The 20-ton electric hoist 2 can fully meet the use requirements. Figure 2 As shown, the electric hoist 2 is installed on the moving track 101, and the electric hoist 2 has a hanging rope 201 for hanging objects below.

[0038] In some implementations of this embodiment, Figure 2 and Figure 4 As shown, a rotating mechanism 3 is suspended below the electric hoist 2, and the rotating mechanism 3 mainly includes a base 302 and a rotating shaft 303. The rotating shaft 303 passes through the center of the base 302, and a rotating disk 304 is fixedly installed on the rotating shaft 303. A bearing 309 that plays a rotating support role is installed between the rotating disk 304 and the base 302. The bearing 309 is an end bearing 309, which can ensure that the rotating shaft 303 rotates smoothly.

[0039] Further, such as Figure 4As shown, a driver 305 and a reducer 306 are installed on the top of the base 302, the output shaft of the driver 305 and the input shaft of the reducer 306 are connected through a coupling, the output shaft of the reducer 306 is vertically upward, the output shaft of the reducer 306 is installed with a pulley 2 308, and a pulley 1 307 is installed on the rotating shaft 303, the pulley 1 307 is located above the rotating disk 304 and is at the same level as the pulley 2 308, and the pulley 1 307 and the pulley 2 308 are connected by a belt. After the driver 305 is started, it can drive the rotating shaft 303 to rotate.

[0040] like Figure 4 As shown, in order to maintain the balance of the base 302, two drivers 305 and two reducers 306 are arranged symmetrically, the driver 305 uses a motor, and two pulleys 1 307 and two pulleys 2 308 are connected by belts. The rotating shaft 303 passes through the bottom end of the base 302 and is connected to two horizontal support rods, and the support rods are connected to the connecting rope 301, and the connecting rope 301 is connected to the fixing mechanism 4.

[0041] Furthermore, four secondary chains 2011 are connected to the bottom end of the suspension rope 201 , and the four secondary chains 2011 are all fixedly connected to the base 302 , and the four secondary chains 2011 are equidistant from each other.

[0042] It should be noted that both the connecting rope 301 and the suspension rope 201 can be anti-twist steel wire ropes.

[0043] In some implementations of this embodiment, Figure 2 and Figure 3 As shown, in this embodiment, two fixing mechanisms 4 are provided, which are respectively connected to the two ends of the pipe segment 7. The fixing mechanism 4 is mainly composed of a limit rod 401 and a support member 402. The limit rod 401 and the support member 402 are both straight rods. The support member 402 is fixed to the upper part of the limit rod 401. When the limit rod 401 is installed inside the pipe segment 7, the support member 402 extends obliquely upward from the outside of the pipe segment 7, so as to facilitate the lifting of the connecting rope 301 and apply a thrust to the upper part of the limit rod 401 toward the center direction of the pipe segment 7.

[0044] Further, combined with Figure 3 and Figure 5As shown, the top and bottom ends of the pipe section 7 are both equipped with anti-skid parts 403, which are arc-shaped cylindrical rods that fit the inner wall of the pipe section 7. The anti-skid parts 403 are fixedly connected to the limiting rod 401, and the top end of the limiting rod 401 is equipped with two symmetrical reinforcing rods 404, which are fixedly connected to the anti-skid parts 403; the bottom end of the limiting rod 401 is equipped with two symmetrical reinforcing rods 404, which are fixedly connected to the anti-skid parts 403. The surface of the anti-skid parts 403 is provided with an anti-skid rubber layer made of rubber material, and the anti-skid parts 403 increase the contact area with the pipe section 7, and the anti-skid rubber layer plays a role in increasing friction, protecting the pipe section 7 and preventing slippage.

[0045] Combination Figure 3 As shown, a groove wheel 4021 or a clamping ring with a break is installed at the end of the support member 402, the end of the connecting rope 301 is fixedly connected to the lower part of the limiting rod 401, and then the connecting rope 301 is clamped into the groove wheel 4021 or the clamping ring from the break to avoid the dangerous situation of the pipe section 7 flipping over.

[0046] The limiting rod 401 is placed obliquely and the top end of the limiting rod 401 is close to the end of the pipe segment 7, and the bottom end of the limiting rod 401 is close to the center of the pipe segment 7. When the electric hoist 2 retracts the lifting rope 201, the connecting rope 301 is tightened, and the connecting rope 301 pulls the bottom end of the limiting rod 401 outward, and the connecting rope 301 applies a thrust to the supporting member 402, pushing the top end of the limiting rod 401 inward. The top and bottom ends of the limiting rod 401 or the anti-slip member 403 are more closely pressed against the inner wall of the pipe segment 7, thereby lifting the pipe segment 7.

[0047] The working principle of the hanging device of the efficient water pipe section for pipe jacking construction of the present invention is as follows:

[0048] Before hanging, the electric hoist 2 is first moved to the pipe segment stacking platform 5, and then the hanging rope 201 is lowered. The operator places the fixing mechanism 4 inside the two sides of the pipe segment 7, and the limit rod 401 is in an inclined state and the top of the limit rod 401 is closer to the pipe mouth side of the pipe segment 7. The connecting rope 301 of the rotating mechanism 3 is connected to the lower part of the limit rod 401, and then the connecting rope 301 passes through the support 402. When hanging, the connecting rope 301 pulls the bottom end of the limit rod 401 outward and upward, and the connecting rope 301 pushes the top end of the limit rod 401 inward through the support 402. The thrust and pulling force work together to make the upper and lower ends of the limit rod 401 clamp the top and bottom of the pipe segment 7 respectively, so as to achieve the fixed connection of the pipe segment 7. The electric hoist 2 lifts the pipe section 7 and moves it to the construction pit 6, then the driver 305 starts to drive the pipe section 7 to rotate. A pull rope can also be connected to the connecting rope 301, and the pull rope is pulled by the worker. Only a slight force is needed to assist the rotation of the pipe section 7, and the shaking of the pipe section 7 can also be reduced, which is convenient for aligning the installation position. The electric hoist 2 lowers the pipe section 7 for installation, and the fixing mechanism 4 can be manually removed after the pipe section 7 is hoisted into place. Compared with the prior art of disassembling the lifting lugs and untying the ropes, it takes less time and is more convenient to install and disassemble. Therefore, the efficient hanging device for the water pipe section for jacking construction of the present invention has a higher hanging and installation efficiency and does not affect the progress of the jacking construction.

When hanging, the upper end of the inclined limiting rod 401 is close to the port side of the pipe segment 7, and the supporting member 402 applies a thrust to the limiting rod 401. The connecting rope 301 applies a pulling force to the limiting rod 401.

The limiting rod 401 is provided with a reinforcing rod 404 connected to the anti-slip member 403. The anti-slip member 403 is configured as an arc-shaped cylinder.
