Description

Technical Field

[0001] The invention is suitable for the mobile hoisting construction of a pipe jacking machine in a confined space, and is particularly suitable for the translation, rotation and hoisting construction of a pipe jacking machine in a confined space in a subway station. Background Art

[0002] The communication passages in subway stations are sometimes constructed with pipe jacking machines. The pipe jacking machines are pushed in from the caisson outside until they are pushed into the exit hole of the side wall of the subway station. When the pipe jacking machine enters the subway station, it is very difficult to move the pipe jacking machine out of the subway station because it is very heavy. The commonly used method is to use a self-locking hydraulic crawler to push the pipe jacking machine to the lifting port, and then lift it out. However, this method moves very slowly and cannot be rotated, so its direct application is also greatly limited.

[0003] At present, most of the existing technologies provide methods for lifting or transporting jacking pipes in confined spaces, and very few are seen about jacking machines. For example: CN201811041083.3 A lifting and hoisting construction process in jacking pipe construction in confined spaces provides a lifting and hoisting construction process in jacking pipe construction in confined spaces that can avoid relocating ground buildings to meet the lifting requirements. It is mainly used for the lifting of a single jacking pipe, rather than a jacking machine. The weight of a jacking machine is much greater than the weight of a single jacking pipe, so the cantilever crane provided cannot be used in a subway station, and the safety is not high. In addition, CN202210765799.8 proposes a method for transporting pipe sections in a confined space. The method transports the pipe jacking to the bottom of the caisson by setting up a conveyor vehicle, a variety of transport tracks, an elevator and a rotating platform. However, since the pipe jacking machine is particularly heavy, an ordinary conveyor vehicle is not capable of doing this. In particular, when the conveyor vehicle receives the pipe jacking machine, the conveyor vehicle needs to resist the horizontal thrust of the pipe jacking machine in the confined space. Therefore, the conveyor vehicle needs to be specially made to be capable of this. In addition, the separate setting of the elevator and the rotating platform cannot synchronously realize the lifting and rotating functions of the pipe jacking machine. Therefore, this method is greatly restricted when used for the translation and rotation of the pipe jacking machine in the subway station.

[0004] In summary, there is an urgent need for a construction method that can both increase the moving speed of the pipe jacking machine in a confined space and simultaneously realize the lifting and rotating of the pipe jacking machine. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a method for moving and hoisting a pipe jacking machine in a confined space.

[0006] This method for moving and hoisting a pipe jacking machine in a confined space includes the following construction steps:

[0007] Step 1. Installation of the fixed part of the construction device: Install the exit frame and the long-side low rail in sequence; then hoist and place the lifting and rotating equipment, symmetrically arrange the scissor hydraulic lift under the hydraulic turntable and fix it, weld the auxiliary rail on the hydraulic turntable; then install the short-side low rail, and connect the long-side low rail, the auxiliary rail and the short-side low rail; assemble the receiving frame and install the winch; hoist and install the large-spacing high rail.

[0008] Step 2. Installation and positioning of the receiving vehicle: Place the receiving vehicle on the long-side low rail through the longitudinal steel wheels, and push the receiving vehicle to the exit side wall; weld a longitudinal hook in front of the chassis, and weld a transverse hook in the middle of the side of the chassis; a transverse steel wheel is also provided under the chassis.

[0009] Step 3. Jacking machine exiting the hole and moving into position: The jacking machine uses the radial rubber wheels on the receiving vehicle to push forward until the entire jacking machine moves onto the receiving vehicle; connect the longitudinal hook to the winch through a pulling rope, and move the receiving vehicle and the jacking machine above the lifting and rotating equipment.

[0010] Step 4. Attitude adjustment of the jacking machine: Remove the pulling rope, start the scissor hydraulic lift until the bottom of the transverse steel wheel exceeds the top height of the large-spacing high rail; start the hydraulic turntable so that the transverse hook on the receiving vehicle faces directly forward; then lower the receiving vehicle until the transverse steel wheel fits with the large-spacing high rail.

[0011] Step 5. The jacking machine moves into position again and is hoisted out: Connect the transverse hook to the winch through a pulling rope, and move the receiving vehicle along the large-spacing high rail to directly below the hoisting opening; remove the pulling rope again, and hoist out the jacking machine.

[0012] Preferably, there is a hoisting opening on the station roof of the subway station. When implementing Step 1, first use the hoisting opening on the subway station to hoist the forklift and the manipulator equipment into the subway station.

[0013] During the installation process of all components in Step 1 and Step 2, the components are hoisted into the forklift in the subway station through the hoisting opening on the subway station, the components are moved to the designated position by the forklift, and then the manipulator equipment is used for the initial fixation of the positions of the components.

[0014] Preferably, in Step 1: The exit frame includes an exit side truss, an exit top truss and an exit bottom truss; after assembling the exit side truss, the exit top truss and the exit bottom truss into one body to form the exit frame, firmly install the exit frame on the exit side wall through expansion bolts.

[0015] One end of the long-side low rail close to the exit side wall is fixed on the exit bottom truss of the exit frame by a transverse anchor beam, and the other end fixes the end sleeper on the station floor of the subway station by expansion bolts; finally, on the station floor, a plurality of groups of anchor ends are symmetrically arranged along both sides of the long-side low rail.

[0016] The lifting and rotating equipment includes a scissor-type hydraulic lift and a hydraulic turntable; after the initial fixation of the lifting and rotating equipment, multiple sets of anchor ends are symmetrically arranged on the station floor along the periphery of the hydraulic turntable, and the lifting and rotating equipment is finally fixed by anchor rods; finally, auxiliary rails are symmetrically welded on the hydraulic turntable, the height and spacing of the auxiliary rails are consistent with the long side low rails and the short side low rails, and the length of the auxiliary rails is equal to the diameter of the hydraulic turntable; the auxiliary rails are connected to the ends of the long side low rails;

[0017] The structure and installation method of the short side low rail are the same as those of the long side low rail, but the length of the short side low rail is shorter than that of the long side low rail; the sleepers at both ends of the short side low rail are fixed to the station floor of the subway station by expansion bolts, and the short side low rail is connected to the end of the auxiliary rail away from the long side low rail.

[0018] Preferably, in step one: the receiving frame includes a receiving side truss, a receiving top truss, a receiving bottom truss and a neutral truss, the two ends of the neutral truss are respectively connected to the middle part of the receiving top truss and the receiving bottom truss, and the entire receiving frame is fixed to the receiving side wall by expansion bolts; after the receiving side truss, the receiving top truss, the receiving bottom truss and the neutral truss are assembled into one, the receiving frame is fixed to the receiving side wall by expansion bolts; finally, two winches are installed and fixed along the height direction on one side of the neutral truss;

[0019] The track gauge of the large-pitch high rail is 2.0 to 3.0 times that of the long-side low rail and the short-side low rail, the track gauge of the large-pitch high rail is larger than the diameter of the hydraulic turntable, and the track gauge of the large-pitch high rail is equal to the longitudinal spacing of the transverse steel wheels on the receiving vehicle, and the height of the large-pitch high rail is 1.1 to 1.2 times the height of the long-side low rail and the short-side low rail; the large-pitch high rail uses a transverse anchor beam to fix the I-beam to the receiving bottom truss of the receiving frame near the receiving side wall end, and a plurality of sets of fixed supports are arranged on the extended part of the large-pitch high rail to be fixed to the station floor of the subway station.

[0020] Preferably, step two is as follows: the receiving vehicle includes a chassis, an arc-shaped frame, a shear brace, a longitudinal hook, a transverse hook, a longitudinal steel wheel, a transverse steel wheel and a radial rubber wheel; first, the chassis is moved to the long side low rail so that the longitudinal steel wheel under the chassis is located on the long side low rail; the arc-shaped frame is welded to the chassis at a spacing of a shear brace length, and the shear brace is welded between adjacent arc-shaped frames, and then the installation of the receiving vehicle is completed in the subway station; the installed receiving vehicle is pushed along the long side low rail to the side wall of the exit hole, and the receiving vehicle is fixed by the surrounding anchor ends and anchor rods.

[0021] Preferably: the length of the chassis is greater than the length of the pipe jacking machine, and the length of the chassis is greater than the gauge of the large-spacing high rail; the width of the chassis is equal to the length of the arc-shaped frame; two pairs of longitudinal steel wheels are symmetrically welded longitudinally under the chassis, and the transverse spacing of the longitudinal steel wheels is equal to the gauges of the long-side low rail, the auxiliary rail, and the short-side low rail, and the longitudinal spacing of the longitudinal steel wheels is greater than the diameter of the hydraulic turntable and less than the gauge of the large-spacing high rail; two pairs of transverse steel wheels are symmetrically welded transversely under the chassis, the transverse spacing of the transverse steel wheels is greater than the transverse spacing of the longitudinal steel wheels, and the longitudinal spacing of the transverse steel wheels is equal to the gauge of the large-spacing high rail.

[0022] The arc-shaped frame is a frame with a semi-circular top surface, and the arc-shaped frame includes a semi-circular arc rod, radial rubber wheels, long legs, inclined legs, and short legs; a plurality of radial rubber wheels are welded at intervals of a certain arc on the upper part of the semi-circular arc rod; long legs and short legs are symmetrically welded at both ends of the semi-circular arc rod, the bottoms of the long legs and the short legs are flush with each other, and inclined legs are welded between the long legs and the short legs; the length of the arc-shaped frame is 1.1 to 1.2 times the diameter of the pipe jacking machine.

[0023] Preferably, step three is specifically as follows: the pipe jacking machine behind the exit side wall is gradually jacked into the fixed receiving vehicle through the exit hole, and the radial rubber wheels on the receiving vehicle are used to jack and move forward one by one. After the entire pipe jacking machine moves onto the receiving vehicle, the anchor rods around the receiving vehicle are removed, and through the pulling rope, the longitudinal pulling hook at the front of the receiving vehicle is connected to the winch under the receiving frame; then the lower winch is slowly started to pull the receiving vehicle and the pipe jacking machine, so that the receiving vehicle and the pipe jacking machine move along the long-side low rail, the auxiliary rail, and the short-side low rail to directly above the lifting and rotating equipment; at this time, the front and rear wheels of the longitudinal steel wheels are respectively on the short-side low rail and the long-side low rail, while the transverse steel wheels are on the outside of the long-side low rail, the auxiliary rail, and the short-side low rail.

[0024] Preferably, in step four: first start the scissor hydraulic lift to raise the hydraulic turntable and the auxiliary rail thereon until the auxiliary rail abuts against the chassis of the receiving vehicle, and then further raise the receiving vehicle and the pipe jacking machine until the bottom of the transverse steel wheels on the receiving vehicle exceeds the top height of the large-spacing high rail by 4 - 6 cm; then start the hydraulic turntable to rotate the receiving vehicle and the pipe jacking machine by 90°, so that the transverse pulling hook on the receiving vehicle faces directly forward; then synchronously start multiple groups of scissor hydraulic lifts to lower the rotated receiving vehicle and pipe jacking machine onto the large-spacing high rail, so that the transverse steel wheels on the receiving vehicle are in line with the large-spacing high rail, and finally lower the lifting and rotating equipment to the original height.

[0025] Preferably, step five is specifically as follows: Connect the horizontal hook at the front of the receiving vehicle to the winch on the upper part of the receiving frame through a pulling rope, then start the upper winch to pull the receiving vehicle and the pipe jacking machine, so that the receiving vehicle and the pipe jacking machine move along the high track with large spacing to directly below the hoisting opening; temporarily fix the horizontal steel wheels, and then remove the pulling rope between the receiving vehicle and the receiving frame again; use the hoisting equipment and the hoisting rope to lift out the pipe jacking machine to complete the moving and hoisting operation of the pipe jacking machine in the confined space.

[0026] The construction device for moving and hoisting the pipe jacking machine in the confined space is obtained by any of the above methods.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1) Compared with the existing flat-pushing method of the self-locking hydraulic crawler, the present invention uses high and low tracks in combination with each other, and realizes the translation of the pipe jacking machine through the receiving vehicle and the winch, keeping its translation speed controllable, and can also synchronously realize the lifting and rotation of the pipe jacking machine, generally accelerating the moving and hoisting process of the pipe jacking machine, so the technical advantages of the present invention are significant.

[0029] 2) Compared with the existing hoisting construction technology in the pipe jacking construction under the confined space, the present invention avoids using a cantilever crane to hoist the pipe jacking machine in the confined space, but uses the hoisting opening at the top of the subway station to hoist the pipe jacking machine, with better safety and effectively avoiding the occurrence of accidents, so the technical advantages of the present invention are significant.

[0030] 3) Compared with the existing method for transporting the pipe jacking pipe joints in the confined space, the present invention specially manufactures a receiving vehicle. By setting the anchoring end and the anchoring rod, the receiving vehicle can completely withstand the horizontal thrust when the pipe jacking machine exits the hole; in addition, by setting radial rubber wheels on the arc-shaped frame of the receiving vehicle, the friction between the pipe jacking machine and the receiving vehicle is greatly reduced, which is beneficial to the smooth reception of the pipe jacking machine.

[0031] 4) The present invention ensures the smooth progress of the first-stage movement process of the pipe jacking machine by setting auxiliary tracks on the hydraulic turntable; the hydraulic turntable and the scissor-type hydraulic lift are concentrically arranged vertically, realizing the integration of the device for the lifting and rotation process of the pipe jacking machine; so the technical advantages of the present invention are significant.

[0061] The following further describes the present invention in conjunction with embodiments. The description of the following embodiments is only used to help understand the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0062] Embodiment 1

[0063] As an embodiment, as Figure 28 shown, a construction method for moving and hoisting out a pipe jacking machine in a confined space, which is characterized by including the following construction steps:

[0064] Step 1, installation of the fixed part of the hoisting construction device, specifically including:

[0065] Installation and fixation of the exit frame: The exit frame 4 is composed of three components, namely, the exit side truss 4-1, the exit top truss 4-2, and the exit bottom truss 4-3. It is fixed on the exit side wall 3 with a exit opening 2 by expansion bolts 10. The exit top truss 4-2 is connected to the station roof slab 8 of the subway station 25. The three components, i.e., the exit side truss 4-1, the exit top truss 4-2, and the exit bottom truss 4-3, are prepared and positioned outside the subway station 25 in advance. Then, using the hoisting opening 5 on the subway station 25, the forklift and the manipulator equipment are first hoisted into the subway station 25, and then the corresponding components are hoisted into the subway station 25. After that, the forklift is used to transport the components to the installation position, and combined with the manipulator equipment, the preliminary position fixation of the components is carried out and assembled into one body. Finally, the exit frame 4 is firmly installed on the exit side wall 3 by expansion bolts 10.

[0066] Installation and fixation of the long-side low rail: The long-side low rail 9 is made in advance using the common railway track 9-1, including the track 9-1 and the sleeper 9-2. The length of the long-side low rail 9 is greater than that of the short-side track 9-1. Then, the long-side low rail 9 is hoisted onto the forklift through the hoisting opening 5, and the position of the long-side low rail 9 is initially fixed using the manipulator equipment. The track 9-1 of the long-side low rail 9 near the exit side wall 3 is fixed on the exit bottom truss 4-3 of the exit frame 4 using the transverse anchor beam 26, and the sleeper 9-2 at the other end is fixed on the station floor slab 7 of the subway station 25 using expansion bolts 10. Finally, on the station floor slab 7, a number of groups of anchor ends 11 are symmetrically arranged along both sides of the long-side low rail 9 for the fixation of the receiving vehicle 21 later.

[0067] Installation and fixation of the lifting and rotating equipment: The lifting and rotating equipment includes a number of groups of scissor-type hydraulic elevators 14 and a hydraulic turntable 13. The prepared number of groups of scissor-type hydraulic elevators 14 and a hydraulic turntable 13 are hoisted onto the forklift through the hoisting opening 5, and the scissor-type hydraulic elevators 14 are symmetrically arranged directly below the hydraulic turntable 13 using the manipulator equipment to complete the initial fixation of the lifting and rotating equipment. Then, on the station floor slab 7, a number of groups of anchor ends 11 are symmetrically arranged again along the periphery of the hydraulic turntable 13, and the lifting and rotating equipment is finally fixed through the anchor rods 12. Finally, a pair of auxiliary rails 15 are symmetrically welded on the hydraulic turntable 13. The height and spacing of the auxiliary rails 15 are the same as those of the long-side low rail 9 and the short-side low rail 90, and the length of the auxiliary rails 15 is the same as that of the hydraulic turntable 13. The two ends of the auxiliary rails 15 are respectively connected to the ends of the long-side low rail 9 and the short-side low rail 90.

[0068] Installation and fixation of the short-side low rail: The production and shape of the short-side low rail 90 are the same as those of the long-side low rail 9, but the length is shorter. The short-side low rail 90 is hoisted onto the forklift through the hoisting opening 5, and the position of the short-side low rail 90 is initially fixed using the manipulator equipment. Then, the sleepers 9-2 at both ends of the short-side low rail 90 are fixed on the station floor slab 7 of the subway station 25 using expansion bolts 10.

[0069] Installation and fixation of the receiving frame: The production of the receiving frame 17 is consistent with that of the exit frame 4, but different in shape and size. It is composed of four components: the receiving side truss 17-1, the receiving top truss 17-2, the receiving bottom truss 17-3, and the neutral truss 17-4. The two ends of the neutral truss 17-4 are respectively connected to the middle parts of the receiving top truss 17-2 and the receiving bottom truss 17-3 up and down. The entire receiving frame 17 is fixed to the receiving side wall 6 by expansion bolts 10; the four components of the receiving side truss 17-1, the receiving top truss 17-2, the receiving bottom truss 17-3, and the neutral truss 17-4 are prepared and positioned outside the subway station 25 in advance. Then, the corresponding components are hoisted to the edge of the receiving side wall 6 through the hoisting opening 5 on the subway station 25, and the preliminary position fixation of the components is carried out by using a manipulator device and assembled into one body. The receiving frame 17 is fixed to the receiving side wall 6 by expansion bolts 10; finally, two winches 20 are installed and fixed along the height direction on one side of the neutral truss 17-4. The center of the upper winch 20 is flush with the transverse hook 21-5 of the receiving vehicle 21 on the large-spacing high rail 18, and the center of the lower winch 20 is flush with the longitudinal hook 21-4 of the receiving vehicle 21 on the long-side low rail 9.

[0070] Installation and fixation of the large-spacing high rail: The large-spacing high rail 18 is made of two I-beams. The spacing between the two I-beams is 2.0 - 3.0 times the gauge of the long-side low rail 9 and the short-side low rail 90, greater than the diameter of the hydraulic turntable 13, and equal to the longitudinal spacing of the transverse steel wheels 21-7 on the receiving vehicle 21. The height of the I-beam is 1.1 - 1.2 times the height of the long-side low rail 9 and the short-side low rail 90; the end of the large-spacing high rail 18 close to the receiving side wall 6 is fixed to the receiving bottom truss 17-3 of the receiving frame 17 by a transverse anchoring beam 26, and multiple groups of fixed braces 19 are arranged on the extension part of the large-spacing high rail 18 and fixed to the station floor 7 of the subway station 25. Finally, the bottom centers of the receiving frame 17, the large-spacing high rail 18, the short-side low rail 90, the lifting and rotating device, and the long-side low rail 9 are located on the same straight line and are orthogonal to the exit side wall 3 and the receiving side wall 6.

[0071] Step 2. Installation of the receiving vehicle in place: Before the receiving vehicle 21 is installed in place, the chassis 21-1, several groups of arc-shaped frames 21-2 and shear braces 21-3 are prefabricated outside the subway station 25, and then they are hoisted and spliced step by step inside the subway station 25. The specific steps are as follows: 1. First, lift the chassis 21-1 through the hoisting opening 5 on the subway station 25 onto a forklift and move it to the predetermined position, and then use the manipulator equipment to move the chassis 21-1 onto the long-side low rail 9, so that the longitudinal rails under the chassis 21-1 are located on the long-side low rail 9; 2. Through the hoisting opening 5 on the subway station 25, hoist and move several groups of arc-shaped frames 21-2 and shear braces 21-3 to the predetermined positions in sequence, and then use the manipulator equipment to weld the arc-shaped frames 21-2 to the chassis 21-1 at intervals of the length of one shear brace 21-3, and weld the shear braces 21-3 between adjacent arc-shaped frames 21-2, thus completing the installation of the receiving vehicle 21 inside the subway station 25; 3. Push the installed receiving vehicle 21 along the long-side low rail 9 to the exit side wall 3, and fix the receiving vehicle 21 through the surrounding anchoring ends 11 and anchor rods 12 for receiving the jacked pipe jacking machine 1.

[0072] The receiving vehicle 21 is composed of eight components: a chassis 21-1, arc-shaped frames 21-2, shear braces 21-3, longitudinal hooks 21-4, transverse hooks 21-5, longitudinal steel wheels 21-6, transverse steel wheels 21-7 and radial rubber wheels 21-8.

[0073] The chassis 21-1 is a stable component welded by profiled steel. It is provided with transverse steel wheels 21-7 and longitudinal steel wheels 21-6 at the bottom, and transverse hooks 21-5 and longitudinal hooks 21-4 on the sides; the length of the chassis 21-1 is slightly longer than the length of the shield machine and greater than the gauge of the large-spacing high rail 18; the width of the chassis 21-1 is equal to the length of the arc-shaped frame 21-2; a longitudinal hook 21-4 is welded in the middle of the transverse short side of the chassis 21-1, and a transverse hook 21-5 is welded in the middle of the longitudinal long side of the chassis 21-1; two pairs of longitudinal steel wheels 21-6 are symmetrically welded longitudinally at the lower part of the chassis 21-1, and the transverse spacing of the longitudinal steel wheels 21-6 is equal to the gauges of the long-side low rail 9, auxiliary rail 15 and short-side low rail 90, and the longitudinal spacing of the longitudinal steel wheels 21-6 is greater than the diameter of the hydraulic turntable 13 and less than the gauge of the large-spacing high rail 18; two pairs of transverse steel wheels 21-7 are symmetrically welded transversely at the lower part of the chassis 21-1, the transverse spacing of the transverse steel wheels 21-7 is greater than the transverse spacing of the longitudinal steel wheels 21-6, and the longitudinal spacing of the transverse steel wheels 21-7 is equal to the gauge of the large-spacing high rail 18.

[0074] The arc frame 21-2 is a semicircular frame, which is also welded with steel sections and is composed of a semicircular arc rod 21-9, a radial rubber wheel 21-8, a long leg 21-10, an oblique leg 21-11 and a short leg 21-12; a plurality of radial rubber wheels 21-8 are welded at a certain interval on the upper part of the semicircular arc rod 21-9 to facilitate the jacking of the pipe jacking machine 1 at the back; two long legs 21-10 and two short legs 21-12 are symmetrically welded at both ends of the semicircular arc rod 21-9, the bottoms of the long legs 21-10 and the short legs 21-12 are flush with each other, and the oblique leg 21-11 is welded between the long legs 21-10 and the short legs 21-12, thereby forming an arc frame 21-2, the length of which is 1.1 to 1.2 times the diameter of the shield machine.
