DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0020] Example: like Figure 1-5 As shown, this embodiment provides a water conveyance tunnel lining steel pipe installation device, including a carrier 1 and a lining pipe 4, a pipe installation mechanism 3 is fixedly installed at the front end of the carrier 1, and the pipe installation mechanism 3 includes a load-bearing frame 31, the load-bearing frame 31 is fixedly installed at the front end of the carrier 1, and a first pressing mechanism 32 and a second pressing mechanism 33 are respectively arranged at the top and near both ends of the load-bearing frame 31, and a pipe lifting device 2 is arranged at the bottom of the load-bearing frame 31, and the pipe lifting device 2 includes a lifting frame 21, and the bottom of the load-bearing frame 31 is hinged to one end of the lifting frame 21 near one end of the carrier 1, and the lifting frame A lifting wheel structure 22 is provided at the bottom of 21, and the pipe installation mechanism 3 lifts one end of the liner pipe 4 from the inside through the second pressing mechanism 33. The lifting frame 21 is contracted by the lifting wheel structure 22 so that one end of it is lower than the outer wall of the liner pipe 4. The pipe lifting device 2 is driven by the carrier 1 to shovel the liner pipe 4 to its top. The pipe installation mechanism 3 is in the liner pipe 4 and clamps the bottom of the inner wall of the liner pipe 4 through the first pressing mechanism 32 and the second pressing mechanism 33. A docking guide wheel structure 5 is provided at the bottom of the connecting end of the two liner pipes 4, and the docking guide wheel structure 5 slides on the foundation surface of the bottom plane of the water conveyance tunnel.

[0021] Specifically, Figure 1-2As shown, the device is driven by a carrier 1, and the carrier 1 can be driven by oil, pneumatic, electric or hybrid power output to provide driving force. The carrier 1 drives the pipe installation mechanism 3 and the pipe lifting device 2, and the second pressing mechanism 33 arranged at the front end of the pipe installation mechanism 3 extends into one end of the liner pipe 4 and lifts it up for a distance. At the same time, the distance between the lifting frame 21 and the ground is adjusted by the lifting wheel structure 22, so that the lifting frame 21 is hinged to the load-bearing frame at one end, so as to achieve the inclination of the lifting frame 21 and lower its front end, so that a trumpet shape is formed between the front end of the lifting frame 21 and the front end of the pipe installation mechanism 3, and then the inner liner pipe 4 is pushed by the carrier 1. The pipe is shoveled into the pipe lifting device 2, and the inner wall of the liner pipe 4 is pressed down by the first pressing mechanism 32 and the second pressing mechanism 33 of the pipe installation mechanism 3. After the lifting wheel structure 22 is reset, it is transported to the liner pipe 4 already placed in the water conveyance tunnel by the carrier 1 for docking. One end of the liner pipe 4 already placed in the water conveyance tunnel is exposed outside the tunnel, and a docking guide wheel structure 5 is pre-installed at the bottom as support and guide. The liner pipe 4 transported by the carrier 1 is docked with the pre-installed lifting wheel structure 22 and the end of another liner pipe 4 and then welded. After the welding is completed, the connected liner pipe 4 is pushed into the water conveyance tunnel by the carrier 1 and the end is reserved, and the installation of the liner pipe 4 is completed in a cycle.

[0022] This device realizes the functions of loading and pushing together by setting up a pipe lifting device 2 and a pipe installation mechanism 3. It can load and dock the pipes by itself, and no auxiliary equipment is needed to transfer the liner pipe 4. The degree of integration is high, which effectively improves work efficiency and productivity. Thirdly, by setting up a docking guide wheel structure 5 to dock with the alignment hole 42 of the alignment block 41 set at the bottom of the liner pipe 4, it can save manpower and material resources for arranging the guide rail structure in the tunnel in advance to transport the liner pipe 4 into the tunnel, thereby greatly saving engineering construction costs.

[0023] The lifting frame 21 includes three channel steels 212, which are evenly arranged along the curvature direction of the bottom of the liner pipe 4. Two adjacent channel steels 212 are connected by the liner pipe 4, and a plurality of lifting pulleys 211 are equidistantly arranged on the top of the channel steel 212 along the length direction.

[0024] The lifting wheel structure 22 includes two sets of wheel brackets 222. The tops of the wheel brackets 222 are hinged to the two ends of the middle channel steel 212. The middle parts of the two sets of wheel brackets 222 are hinged to the two ends of the connecting rod 223 respectively. The connecting rod 223 is hinged to the end of the telescopic shaft of the driving hydraulic cylinder 224 near one end. The cylinder seat of the driving hydraulic cylinder 224 is hinged to the bottom of the middle channel steel 212 near the other end of the connecting rod 223. Both ends of the bottom of the wheel bracket 222 are connected to guide wheels 221 by bearings.

[0025] Specifically, Figure 2-3As shown, by driving the hydraulic cylinder 224 to extend and retract, the connecting rod 223 can be driven to move away from or close to the lifting frame 21, so that the two sets of wheel brackets 222 are driven to fold synchronously through the connecting rod 223, so as to realize the overall lifting of the lifting frame 21. At the same time, since the lifting frame 21 is hinged with the bottom of the supporting frame 31, an inclined posture is formed, which is convenient for shoveling the liner pipe 4 from the bottom, and a plurality of lifting pulleys 211 are equidistantly arranged on the top of the channel steel 212. When the lifting frame 21 shovels the liner pipe 4, the lifting pulley 211 slides in contact with the liner pipe 4, so that the liner pipe 4 can be shoveled in more smoothly, and at the same time, it can also prevent the lifting frame 21 from scratching the outer surface of the liner pipe 4, thereby affecting the quality of the project.

[0026] The support frame 31 is in a horizontal L-shaped structure, and one end of the lifting frame 21 is hinged to the bottom end of the vertical side of the support frame 31 .

[0027] The first pressing mechanism 32 and the second pressing mechanism 33 have the same structure and are disposed on the top of the supporting frame 31 in a mirror image.

[0028] The first pressing mechanism 32 includes two sliding sleeves 321 arranged side by side along the width direction of the supporting frame 31, and a lifting frame 323 is slidably connected between the two sliding sleeves 321 along the vertical direction. The bottom of the lifting frame 323 passes through the bottom of the sliding sleeve 321, and the bottom center of the lifting frame 323 is fixedly installed with the top of the telescopic shaft of the lifting hydraulic cylinder 324. The cylinder seat of the lifting hydraulic cylinder 324 is fixedly installed on the top of the supporting frame 31, and the top and bottom of one side of the lifting frame 323 are respectively fixedly installed with a lifting block 322 and a clamping block 325.

[0029] The vertical position of the second pressing mechanism 33 exceeds the front end of the pipe lifting device 2 .

[0030] Specifically, Figure 2-3 As shown, the second pressing mechanism 33 is arranged beyond the front end of the pipe lifting device 2, so that it can first contact the liner pipe 4, and drive the lifting frame 323 upward through the lifting hydraulic cylinder 324, thereby driving the lifting block 322 to lift one end of the liner pipe 4 off the ground, so as to facilitate the pipe lifting device 2 to shovel and drag from the bottom of the liner pipe 4. After the liner pipe 4 is shoveled into the pipe lifting device 2, the two groups of lifting frames 323 are driven downward by two groups of lifting hydraulic cylinders 324, thereby driving the two clamping blocks 325 to move downward and press the inner wall of the liner pipe 4, thereby clamping the liner pipe 4 together with the lifting frame 21 at the bottom of the liner pipe 4. Through this structural setting, the liner pipe 4 stacked on the ground can be independently lifted, shoveled and installed without the help of other lifting equipment or manpower, thereby greatly simplifying the process steps of the installation of the liner pipe 4, and at the same time effectively improving the construction efficiency of the liner pipe 4, while improving the degree of mechanization and greatly reducing the construction risks caused by manual operation, and effectively protecting the lives of construction personnel.

[0031] Alignment blocks 41 are provided on both sides of the bottom of the inner liner tube 4 and close to the front and rear ends respectively. An alignment hole 42 is provided in the middle of the alignment block 41 close to the end of the inner liner tube 4 .

[0032] The docking guide wheel structure 5 includes a docking plate 51, and docking columns 52 are arranged on the left and right sides of the docking plate 51 and close to both ends respectively. The docking columns 52 are plugged into the corresponding alignment holes 42. A wheel frame 53 is arranged at the bottom of the docking plate 51, and rollers 54 are connected to the two ends of the wheel frame 53 by bearings. The docking columns 52 are of a truncated cone structure, and the shape of the alignment holes 42 matches the shape of the docking columns 52.

[0033] Specifically, Figure 4-5 As shown, two groups of two alignment blocks 41 are respectively arranged at both ends of the bottom of the liner pipe 4, each group of two alignment blocks 41, and the two alignment blocks 41 in the same group are plugged into the two docking columns 52 on the same side of the docking guide wheel structure 5. Since the docking column 52 is a truncated cone structure with a small front end and a large rear end, a certain docking error range is allowed during the docking process, thereby facilitating docking. After docking, it is welded around the liner pipe 4 so that the docking guide wheel structure 5 is clamped and fixed between the two groups of alignment blocks 41, and contacts the bottom plane of the tunnel through the roller 54 at its bottom, and moves inward by rolling.

[0034] The carrier vehicle 1 is provided with a loading area 11, and the interior of the loading area 11 is counterweighted with matching counterweight blocks 12 according to the weight of the liner pipe 4. Different types of liner pipes 4 are matched by adapting counterweight blocks 12 of different weights, and the strong propulsion force of the carrier vehicle 1 is used to provide powerful power for the installation of the liner pipe 4. After all the liner pipes 4 are loaded into the tunnel, the installation process is completed by pouring concrete between the liner pipes 4.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
