Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 In an embodiment of the present invention, a lifting and fixing device for installing an engineering pipeline includes a mobile base 1. A plurality of load-bearing wheels are rotatably mounted on the bottom of the mobile base 1. A driving mechanism for moving each load-bearing wheel is installed inside the mobile base 1. The driving mechanism is implemented using existing technical means. During the installation of the pipe, the mobile base 1 drives the entire device to move along the laying and installation direction of the pipe, and the installation of multiple sections of pipe is completed in sequence, thereby improving the lifting and installation efficiency of the entire device.

[0026] A column 2 is fixedly connected to one side of the mobile base 1, and an adjusting hydraulic cylinder is fixedly installed on the top of the inner wall of the column 2. The output end of the adjusting hydraulic cylinder is downwardly arranged and fixedly connected to a docking frame 3, and a lifting frame 4 is fixedly connected to the inner wall of the docking frame 3. The docking frame 3 is driven up and down by the adjusting hydraulic cylinder, and then the lifting frame 4 is driven up and down, so that the device can meet the lifting and installation requirements of pipes at different construction heights;

[0027] A limiting mechanism for limiting and supporting the junction of two sections of pipes is provided on one side of the bottom of the lifting frame 4. The limiting mechanism includes a number of equidistantly arranged limiting units, and the limiting unit includes an adjusting hanging plate 5. The bottom of the adjusting hanging plate 5 is slidably connected to two parallel limiting members. The limiting member includes a limiting hanger 6. The middle part of the limiting hanger 6 is provided with a docking guide groove for the pipe to pass through. The inner wall of the docking guide groove is rotatably connected to a number of guide rollers 7 distributed at equal angles. Each limiting unit is provided with two limiting members to support and limit the ends of the two pipes to be connected, so as to facilitate the connection and installation of the pipes by the operators.

[0028] A plurality of limit adjustment rods 8 are equidistantly arranged along the edge of the limit hanger 6 and are slidably connected between the two limit hangers 6. By providing a plurality of limit adjustment rods 8, the docking guide grooves on the two limit hangers 6 are ensured to be stably aligned, thereby enabling the two sections of pipe to be accurately aligned.

[0029] The tops of the two limit hangers 6 are both threadedly connected with adjustment bolts, and the middle of the adjustment hanging plate 5 is provided with an adjustment slot for sliding the adjustment bolts. The limit hangers 6 and the adjustment hanging plate 5 are limited by the adjustment bolts to achieve the adjustment of the distance between the two limit hangers 6, thereby facilitating the adjustment of the distance between the two limit hangers 6 according to the requirements of different installation spaces;

[0030] The top center of the adjustment hanging plate 5 is rotatably connected to a lifting screw 9, and the top of the lifting screw 9 is threadedly connected to the bottom of the lifting frame 4; the middle of the lifting screw 9 is fixedly connected to a turning handle. By rotating the turning handle, the lifting screw 9 is driven to rotate, thereby adjusting the height of the adjustment hanging plate 5, and then adjusting the distance between the limit hanging frame 6 and the docking guide groove and the lifting plate to meet different installation requirements;

[0031] To prevent the adjusting plate 5 from rotating along with the lifting screw 9 , both sides of the top of the adjusting plate 5 are fixedly connected with limit rods 10 , and the tops of the two limit rods 10 are slidably connected to the bottom of the lifting frame 4 .

[0032] A supporting mechanism for temporarily supporting the pipes to be installed is provided on the other side of the bottom of the lifting frame 4; the supporting mechanism includes a plurality of supporting sliding grooves 14, the inner walls of which are fixedly connected to supporting members, which include sliding hanging plates 17, and the bottom of the sliding hanging plates 17 is fixedly connected to a supporting bracket 12, which is arranged in a C shape, and the top side length of the supporting bracket 12 is slightly shorter than the bottom side length, so as to facilitate the movement of the pipes into the supporting bracket 12;

[0033] In order to improve the position stability of the pipe in the support bracket 12, a flip baffle 16 is rotated on one side of the bottom of the support bracket 12, and one side of the flip baffle 16 is engaged with the support bracket 12. When the pipe is not moved into the support bracket 12, the flip baffle 16 is not engaged with the support bracket 12 and naturally loosens and droops to reduce the obstruction of the pipe entering the support bracket 12. After the pipe is moved into the support bracket 12, the flip baffle 16 is rotated to engage with the support bracket 12. The pipe box is pushed into the support bracket 12 by the pushing effect of the flip baffle 16 during the flipping process. At the same time, the engagement of the flip baffle 16 with the support bracket 12 also plays a role in blocking and limiting the pipe.

[0034] The inner wall of the support frame 12 is provided with several roller grooves, the inner walls of the several roller grooves are fixedly connected with supporting springs, one end of the supporting springs is fixedly connected with a roller frame, and the inner wall of the roller frame is rotatably connected with a supporting roller 13. By arranging structures such as the supporting roller 13 and the supporting spring, the resistance of the pipe when it is pushed along the inside of the support frame 12 is reduced, making the installation operation of the operator more labor-saving and convenient.

[0035] A lifting mechanism for lifting and hoisting the pipes is provided on the top of the mobile base 1. The lifting mechanism includes a loading support plate 19. A traction plate 20 is fixedly connected to one side of the loading support plate 19. The traction plate 20 is slidably connected to the inner wall of the column 2. One side of the column 2 is fixedly connected to the chassis 18. A winch is fixedly installed on the inner wall of the chassis 18. The top of the traction plate 20 is fixedly connected to the output end of the winch through a steel cable 21. The winch drives the traction plate 20 and the loading support plate 19 to move, thereby realizing continuous lifting and movement of the pipes.

[0036] In order to improve the stability of the pipe during the lifting and moving process, a placement groove is opened in the middle of the loading pallet 19, and the placement groove is set as a V-shaped groove. A loading trough is opened in the middle of the mobile base 1. The loading pallet 19 is set corresponding to the loading trough. When the bottom of the loading pallet 19 is in contact with the bottom of the loading trough, the top of the loading pallet 19 is flush with the top surface of the material transfer chassis to facilitate the loading of the pipe.

[0037] A lateral displacement groove 15 is provided on one side of the two supporting sliding grooves 14. When necessary, the sliding hook can be slid out along the side displacement groove to drive the supporting frame 12 and the pipe to the side and lower side of the lifting plate, thereby reducing the obstruction of the lifting operation of the lifting plate and the pipe.

[0038] In order to improve the stability of the entire device during lifting operations, a counterweight block 22 is fixedly connected to the side of the mobile base 1 away from the column 2. To facilitate the loading operation of the pipe, the top surface of the counterweight block 22 is set at an angle.

[0039] When the present invention is in use, the base 1 is moved to the pipe installation position through the driving mechanism, and the pipe to be installed is placed in the placement groove of the loading support plate 19. The winch is started, and the traction plate 20 is pulled up by the steel cable 21, thereby driving the loading support plate to move up. When the pipe in the placement groove moves to the same height as the support bracket 12, the pipe is manually pushed into the support bracket 12, and the pipe is supported by a plurality of support brackets 12, and then the pipe is pushed along the length direction of the pipe so that one end of the pipe passes through the limit hanger. 6, and manually dock it with the end of the previously installed pipe or the pipe installation position on other components. After the installation is completed, the mobile base 1 drives the device as a whole to move along the length direction of the pipe until the other end of the installed pipe is located between the two limit hangers 6, completing the installation operation of the section of pipe, and then the winch is reversed, the loading support plate is reset, and falls into the loading trough, and then the new pipe is pushed by the top surface of the counterweight block 22 into the placement groove of the loading support plate 19, and the lifting and installation of the pipe are continued.
