Description

Technical Field

[0001] The invention belongs to the field of engineering transport trolleys, and in particular relates to an integrated trolley for transporting and installing lining steel pipes in a water conveyance tunnel and a construction method thereof. Background Art

[0002] In order to minimize the impact of route construction on the ground, improve the utilization rate of ground and underground land resources, and avoid the impact of tunnels on ground houses, roads, underground subway tunnels, circuit communications and other municipal tunnels as much as possible, water resource allocation projects often design routes deep underground.

[0003] Hydraulic tunnels carry important functions such as water diversion, water delivery, and drainage. During construction, tunnel steel pipes are usually transported into the tunnel by a trolley. After contacting the previous section of steel pipes, the position of the steel pipes is changed by lateral movement and height raising and lowering to align with the previous section of steel pipes, and then the steel pipes are welded and subsequently processed.

[0004] At present, the existing trolleys have the following deficiencies when transporting and installing steel pipes in tunnels: 1. When the trolley transports the steel pipe and approaches the previous section of steel pipe in the tunnel, the port of the steel pipe on the trolley will gradually approach the port of the previous section of steel pipe and eventually collide with it. Due to the large deadweight between the trolley and the steel pipe, when the steel pipe on the trolley collides with the previous section of steel pipe, there is a large impact force due to inertia, which may have an adverse effect on the original installed steel pipe, and ultimately reduce the overall installation quality of the steel pipe in the tunnel. 2. When the steel pipe on the trolley collides with the previous section of steel pipe for alignment, it is usually manually measured by tools and visually assisted observation to determine whether it is aligned. Due to the narrow space and harsh environment in the tunnel, the method of measuring with tools is not only inefficient, but also relatively more difficult to operate. Summary of the invention

[0005] In view of the above problems, an integrated trolley for transporting and installing steel pipes for lining a water supply tunnel and a construction method thereof are provided in an embodiment of the present application, which can greatly reduce the impact force of two steel pipes when they are butted together, making the butt installation more stable.

[0017] S2, steel pipe placement, the steel pipe is placed on the limit frame through the first sliding assembly and the external lifting equipment, and the height of the rear section of the steel pipe is adjusted to be the same as the height of the front section of the steel pipe in the tunnel through four hydraulic jacks.

[0036] The following is combined with Figure 1-8 The present application is further described in detail.

[0037] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6A transport and installation integrated trolley for lining steel pipes in water conveyance tunnels, comprising a chassis 1 with a rectangular frame structure, a moving mechanism 2 is commonly arranged between the front and rear ends of the chassis 1, a first fine-tuning mechanism 3 is arranged on the chassis 1, a plurality of guide wheels 4 in contact with the ground are arranged on the first fine-tuning mechanism 3, two left-right symmetrical slide rails 5 are arranged on the first fine-tuning mechanism 3, a second fine-tuning mechanism 6 is commonly arranged on the two slide rails 5, a plurality of balls 7 are movably arranged between the second fine-tuning mechanism 6 and the chassis 1, a limiting frame 8 for supporting and limiting the steel pipe is arranged on the second fine-tuning mechanism 6, and the limiting frame 8 comprises a supporting base 801 with a rectangular structure, two front-to-back symmetrical hydraulic jacks 802 are fixedly arranged on the left and right side walls of the supporting base 801, four hydraulic jacks 802 are all arranged on the second fine-tuning mechanism 6, and a diagonal brace plate 803 movably abutting against the steel pipe is fixedly arranged at the telescopic end of the hydraulic jack 802. A detection mechanism 9 for measuring the alignment of the steel pipe installation is arranged on the chassis 1. The steel pipe is hoisted onto the limit frame 8 by external lifting equipment, and then the steel pipe is lifted to a certain height which is the same as the height of the steel pipe in the tunnel by four hydraulic jacks 802, and then the detection mechanism 9 is inserted into the pipeline, and then the steel pipe is driven into the tunnel by the moving mechanism 2. When the steel pipe on the limit frame 8 is close to the port of the previous steel pipe for a certain distance, it stops, and then the first fine-tuning mechanism 3 is used to control the steel pipe port on the limit frame 8 to slowly approach the port of the previous steel pipe, so that the two steel pipe ports can slowly and tightly fit, and with the cooperation of the second fine-tuning mechanism 6, the two steel pipes are aligned and detected by the detection mechanism 9.

[0038] See also Figure 1 The moving mechanism 2 includes two mounting seats 201 fixedly arranged on the front side wall of the chassis 1 and symmetrically arranged on the left and right sides. A driving wheel 202 with a brake plate is rotatably arranged on the mounting seat 201, and a reduction motor 203 is arranged on the front side wall of the mounting seat 201. The output shaft of the reduction motor 203 is connected to the corresponding driving wheel 202 through a first sprocket group. Two driven wheels 204 are symmetrically arranged on the rear end of the chassis 1. The reduction motor 203 cooperates with the first sprocket group to drive the driving wheel 202 to rotate, and the two driven wheels 204 at the rear end of the chassis 1 follow and move, driving the entire trolley to move.

[0039] See also Figure 2 , Figure 3 and Figure 4Two first adjustment holes that are symmetrical front and back are opened on the upper left and right sides of the chassis 1. The first fine-tuning mechanism 3 includes two fourth screws 301. The fourth screw 301 is rotatably set between the two first fine-tuning holes corresponding to the front and rear. The front and rear ends of the fourth screw 301 are threaded with first slides 302. The first slide 302 is slidably set in the first adjustment hole. The corresponding left and right first slides 302 are fixedly connected to the corresponding slide rails 5. The guide wheel 4 is fixedly set at the lower part of the first slide 302. The rear ends of the two fourth screws 301 are jointly connected through the second sprocket set. One end of any one of the fourth screws 301 is fixedly connected to the output shaft of the fifth motor. The fifth motor is fixedly set on the rear side wall of the chassis 1. The fifth motor cooperates with the second sprocket group to enable the two fourth screw rods 301 to rotate synchronously, so that the four first slides 302 can move synchronously to drive the slide rail 5 to move. The guide wheel 4 arranged under the first slide 302 can contact the ground to support the first slide 302, avoiding the problem of excessive pressure on the fourth screw rod 301 caused by the first slide 302 being suspended in the air, thereby allowing the slide rail 5 to move back and forth along the length direction of the chassis 1.

[0040] See also Figure 2 and Figure 6 , second adjustment holes are provided at both left and right ends of the upper part of the slide rail 5, the second fine-tuning mechanism 6 includes two fifth screw rods 601, the fifth screw rod 601 is rotatably arranged between the two left and right second adjustment holes, the left and right ends of the fifth screw rod 601 are threadedly connected with the second slide seat 602, the second slide seat 602 is slidably arranged in the corresponding second adjustment hole, the ball 7 is movably arranged at the lower part of the second slide seat 602, and the ball 7 is rollingly arranged on the upper surface of the chassis 1, the limit frame 8 is fixedly arranged on the upper part of the four second slide seats 602, the left ends of the two fifth screw rods 601 are connected together by the third sprocket group, one end of any one of the fifth screw rods 601 is fixedly connected with the output shaft of the sixth motor, and the sixth motor is fixedly arranged on the right side wall of the corresponding slide rail 5. The second slide 602 is connected to the chassis 1 by the sixth motor and the third sprocket group to synchronously drive the two fifth screw rods 601 to rotate, so that the four second slides 602 can drive the limit frame 8 to move back and forth along the width direction of the chassis 1, and the ball 7 arranged under the second slide 602 rolls and abuts against the upper part of the chassis 1 to support the second slide 602, thereby avoiding the problem of excessive pressure on the fifth screw rod 601 caused by the second slide 602 being suspended in the air.

[0041] In order to reduce the impact force when the two steel pipes collide, the steel pipe is driven by the moving mechanism 2 on the chassis 1 to move toward the previous section of the steel pipe, and slows down and stops in advance when the two steel pipe ports are about to contact. At this time, there is a certain distance between the two steel pipe ports, and then the first fine-tuning mechanism 3 drives the limit frame 8 to drive the steel pipe to continue to move toward the previous section of the steel pipe, so that the steel pipe of the limit frame 8 finally collides with the previous section of the steel pipe smoothly, effectively reducing the inertial impact. At the same time, the four hydraulic jacks 802 on the limit frame 8 can work at the same time to lift the steel pipe to the same height as the previous section of the steel pipe, and then the second fine-tuning mechanism 6 can drive the steel pipe on the limit frame 8 to translate left and right, further assisting the alignment of the two steel pipes.

[0042] See also Figure 1 , Figure 2 , Figure 4 and Figure 8 The detection mechanism 9 includes a first sliding component 901 arranged on the chassis 1, the sliding component is connected to a first telescopic component 902, the telescopic component is provided with a horizontal plate 903, the horizontal plate 903 is provided with a positioning component 904 for determining the center of the steel pipe, and a second sliding component 905 is also provided at the rear end of the horizontal plate 903, the second sliding component 905 is provided with a first motor 906, the output shaft of the first motor 906 is fixedly connected to a second telescopic component 907, and the second telescopic component 907 is provided with a pressure detector 908. The second telescopic component 907 includes a first connecting plate 9071 fixedly connected to the output shaft of the first motor 906, and the second connecting plate 9072 is movably connected to the end of the first connecting plate 9071 away from the first motor 906, and the surface of the second connecting plate 9072 is provided with a plurality of limiting holes distributed along the length direction of the second connecting plate 9072, and the first connecting plate 9071 is threaded with locking bolts movably connected to the limiting holes, so that the relative lengths of the two can be adjusted as needed, and the second connecting plate 9072 is provided with a movable groove at one end away from the first connecting plate 9071, and a first spring 9073 is fixedly arranged in the movable groove, and the end of the first spring 9073 close to the movable groove port is fixedly connected to the pressure detector 908.

[0043] In order to reduce the difficulty of calibrating the two steel pipes, the first sliding component 901 drives the cross plate 903 to move relative to the chassis 1, and the pressure detector 908 lying across the chassis 1 is removed, so that the steel pipe can be smoothly placed on the limit frame 8 through the external lifting equipment. At the same time, the steel pipe is lifted to the same level as the steel pipe in the tunnel through the hydraulic jack 802. After the steel pipe is placed, the first sliding component 901 drives the pressure detector 908 to reset, so that the pressure detector 908 is inserted into the interior of the steel pipe, and then the positioning component 901 is 04 works, the positioning component 904 can be fixed on the inner wall of the steel pipe and force the cross plate 903 to be at the same height level as the axis of the steel pipe. At this time, the pressure detector 908 is movably abutted against the inner wall of the steel pipe, and the pressure when the inner wall of the steel pipe and the pressure detector 908 are abutted is measured. The pressure detector 908 is driven to rotate by the first motor 906 to detect whether the pressure deviation of the pressure detector 908 is large after one rotation, and reversely judge whether the center line of the cross plate 903 is at the same position as the axis of the steel pipe. When the steel pipe on the limit frame 8 is aligned with the previous section of steel pipe and it is necessary to detect the alignment of the two steel pipes, the second sliding component 905 extends to drive the pressure detector 908 to move from the latter section of the steel pipe to the inner wall of the former section of the steel pipe. Since the position of the cross plate 903 relative to the latter steel pipe has not changed, when the first motor 906 drives the second telescopic component 907 to rotate, the pressure detector 908 moves in a circular motion along the inner wall of the former section of the steel pipe. The pressure of the inner wall of the steel pipe acting on the pressure detector 908 is measured by the pressure detector 908 (the influence of the gravity of the pressure detector 908 itself is negligible). If the two steel pipes are not aligned, it means that the centers of the two steel pipes are not on the same axis. At this time, there will be a large deviation between the data detected by the pressure detector 908 in a certain area of ​​the former section of the steel pipe and the data measured in the steel pipe on the limit frame 8. The staff can judge whether the two steel pipes are aligned based on the detection data and make corresponding adjustments to the steel pipe on the limit frame 8. If the two steel pipes are aligned and the centers of the two steel pipes are on the same axis, and the pressure data measured by the pressure detector 908 after one rotation in the previous section of the steel pipe is basically the same as the pressure data measured in the limit frame 8, it means that the two steel pipes are aligned. The second sliding component 905 can be used to drive the pressure detector 908 to adjust its position in the previous section of the steel pipe for repeated measurements to finally determine whether the two steel pipes are aligned. After confirming the alignment, subsequent processing can be carried out.

[0044] See also Figure 1 , Figure 4 and Figure 6The first sliding assembly 901 is fixedly arranged between the front and rear inner walls of the chassis 1 and the two first guide rods 9011 are symmetrical to each other. A tooth plate 9012 is slidably connected between the two first guide rods 9011. The rear end of the tooth plate 9012 is movably plugged with the rear inner wall of the chassis 1. The front end of the tooth plate 9012 movably penetrates the front side wall of the chassis 1, and the front upper part of the tooth plate 9012 is fixedly connected with the first telescopic assembly 902. The front side wall of the chassis 1 is fixedly arranged with a second motor, and the output shaft of the second motor is fixedly connected with a first gear 9013 meshing with the tooth plate 9012. The second motor drives the first gear 9013 to rotate so that the tooth plate 9012 can slide along the length direction of the chassis 1, and the pressure detector 908 above the chassis 1 is controlled to slide along the length direction of the chassis 1.

The rotation of the second screws 9045 can drive the support blocks 9042 to move radially along the disk 9041 until the four support blocks 9042 abut against the inner wall of the steel pipe at the same time.

[0047] In order to adapt to the calibration and detection of different steel pipes, the first telescopic component 902 can quickly adjust the horizontal plate 903 to a height roughly the same as the center of the steel pipe. At the same time, when the four top support blocks 9042 on the positioning component 904 are movably abutted against the inner wall of the steel pipe, the horizontal plate 903 is fixedly connected to the disc 9041, and the disc 9041 will drive the horizontal plate 903 to move and finally be fixed at the center of the steel pipe. The front end of the horizontal plate 903 is movably plugged with the second column 9023 through the third column 9024, so that the horizontal plate 903 can move a short distance with the disc 9041. Ensure that the output shaft of the first motor 906 at the rear end of the horizontal plate 903 and the steel pipe are at the same center, which is convenient for the subsequent comparison of the two steel pipes after pressure detection.

[0048] See also Figure 1 and Figure 6 The rear end of the horizontal plate 903 is provided with a sliding hole, and the second sliding assembly 905 includes a third screw 9051 rotatably arranged in the sliding hole, and the third screw 9051 is threadedly connected with a third connecting plate 9052 slidably arranged in the sliding hole, and the rear end of the third connecting plate 9052 movably penetrates the rear end of the horizontal plate 903 and is fixedly connected to the first motor 906, and the horizontal plate 903 is fixedly provided with a seventh motor, and the output shaft of the seventh motor is fixedly connected to the third screw 9051. The third screw 9051 is driven to rotate by the seventh motor so that the third connecting plate 9052 can slide along the length direction of the horizontal plate 903, thereby pushing the pressure detector 908 originally in the steel pipe to be installed into the previous section of the installed steel pipe for corresponding pressure detection.

[0049] In addition, the present invention also provides a water conveyance tunnel lining steel pipe construction method, which is used in conjunction with the above-mentioned water conveyance tunnel lining steel pipe transportation and installation integrated trolley, comprising the following steps:

[0050] S1. Parameter adjustment. The height of the horizontal plate 903 is adjusted through the first telescopic component 902 to ensure that the height of the horizontal plate 903 is basically the same as the height of the axis of the steel pipe after the steel pipe is placed on the limit frame 8. At the same time, by adjusting the relative lengths of the first connecting plate 9071 and the second connecting plate 9072, the pressure detector 908 can abut against the inner wall of the steel pipe when entering the steel pipe.

[0051] S2. Placement of the steel pipe. The horizontal plate 903 and the pressure detector 908 originally lying across the limit frame 8 are removed from above the limit frame 8 by the first sliding assembly 901. The steel pipe to be installed is transported outside the water tunnel by the lifting equipment and placed on the limit frame 8. The height of the rear section of the steel pipe is adjusted to be flush with the height of the front section of the steel pipe by the hydraulic jack 802. Then the first sliding assembly 901 is reset. At the same time, the staff assists and inserts the horizontal plate 903 and the pressure detector 908 into the steel pipe.

[0052] S3. Perform pressure testing on the steel pipe to be installed. The positioning assembly 904 is actuated so that the center of the disc 9041 is fixed co-center with the steel pipe. At this time, the pressure value of the inner wall of the steel pipe on the pressure detector 908 is detected by the pressure detector 908.

[0053] S4, preliminary docking, using the moving mechanism 2 to move the entire structure along the tunnel close to the previous section of steel pipe that has been installed and fixed in the tunnel, and brake and stop in advance when it is about to contact the previous section of steel pipe, so that there is a certain distance between the end of the previous section of steel pipe and the steel pipe to be installed.

[0054] S5, depth alignment, the first fine-tuning mechanism 3 drives the steel pipe to be installed to move toward the end of the previous steel pipe again, and finally makes the two stably collide, and then the second fine-tuning mechanism 6 can drive the steel pipe to be installed to move left and right to further adjust so that the steel pipe to be installed can finally be aligned with the previous steel pipe.

[0055] S6, calibration, the pressure detector 908 originally in the steel pipe to be installed is sent into the previous section of the steel pipe through the second sliding component 905, and then the second telescopic component 907 is driven by the first motor 906 to rotate and drive the pressure detector 908 to rotate in the previous end of the steel pipe. The staff compares the data detected by the pressure detector 908 with the pressure value detected in step S3 to determine whether the two steel pipes are aligned. If the deviation exceeds the threshold, it means that they are not fully aligned and need to be adjusted accordingly. If the deviation is within the threshold, it means that they are fully aligned.

[0056] S7. The trolley is withdrawn, the aligned steel pipes are welded, and then the steel pipes are reinforced with steel bars. After that, the hydraulic jack 802 is retracted and the entire pipe is moved out of the tunnel.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
