[0024] The two side clamps 7 are fixedly mounted with a locking rod 8, and the two side clamps 7 are fixedly mounted with a shaped frame 9 on the side away from each other. A one-way screw 10 is rotatably mounted in the two shaped frames 9, and a lifting block 11 is threadedly mounted on the two one-way screws 10. The ends of the two locking rods 8 away from each other are respectively fixedly connected to the two lifting blocks 11, and two sliding rods 3 are installed in the two shaped frames 9. The corresponding two sliding rods 3 penetrate the corresponding lifting blocks 11 and are slidably connected to the corresponding lifting blocks 11, and a motor 1 is fixedly mounted on the top of the two shaped frames 9.

[0025] The provided lifting mechanism includes a U-shaped frame II 17, and the U-shaped frame II 17 is fixedly installed at the bottom of the connection block 16. Two winding rods 18 are rotatably installed in the U-shaped frame II 17. Two lifting ropes 19 are wound around each of the two winding rods 18. One end of each of the four lifting ropes 19 is fixedly connected to the corresponding winding rod 18, and the other ends of the four lifting ropes 19 are fixedly installed with the same bearing plate 20.

The two gears are engaged with each other, so that the two winding rods 18 can rotate simultaneously and in opposite directions, and thus the four lifting ropes 19 can be wound or released simultaneously.

[0026] In this mode, an activity port is opened on the side of the gantry 1 away from the shuttle port 2. The provided box body 12 and the cross bar 15 both pass through it, and the cross bar 15 is separated from the inner wall of the activity port.

[0027] The working principle of the lifting device for pressure pipeline installation applicable to narrow spaces provided by the present utility model is as follows:

[0028] When placing the pipeline in a narrow space, first move the gantry 1 to a specified position so that the pipeline is located between the two side clamping plates 7. Then, start the motor II in the forward direction, and its output shaft drives the bidirectional lead screw 4 to rotate. At this time, the two transverse moving plates I 5 move towards each other, so that the two side clamping plates 7 approach each other. Finally, the two side clamping plates 7 are used to clamp both sides of the pipeline. Immediately afterwards, start the two motors I in the forward direction. The output shafts of the two motors I drive the corresponding one-way lead screws I 10 to rotate. At this time, by means of the threaded fit between the one-way lead screw I 10 and the lifting block 11, the two lifting blocks 11 drive their corresponding clamping rods 8 to rise until the clamping rods 8 rise to abut against the inner wall of the top of the pipeline, and then turn off the motor I. At this time, the clamping of the pipeline is completed;

[0029] Subsequently, start the motor III in the forward direction, and its output shaft drives the corresponding winding rod 18 to rotate. Under the meshing action of the two gears, the two winding rods 18 rotate synchronously and in opposite directions, and thus start to wind the four lifting ropes 19. As the lifting ropes 19 are wound, the bearing plate 20 drives the frame body 3 and the pipeline clamped below to rise until the pipeline is lifted to a high place, and then turn off the motor III. Immediately afterwards, move the gantry 1 and move the gantry 1 to the front of the narrow space so that the shuttle port 2 faces the narrow space;

[0030] Then, start motor 4 in the forward direction, and its output shaft drives the one-way screw 2 13 to rotate, and through the threaded cooperation with the transverse plate 2 14, the transverse plate 2 14 moves horizontally with the cross bar 15, and the side clamping plate 7 with the pipeline will pass through the shuttle port 2 into the narrow space. After the pipeline moves to the top of the pre-buried foundation pit, start motor 3 in the reverse direction, and the four lifting ropes 19 begin to be released, and the pipeline will descend. After the pipeline is lowered into the foundation pit, start motor 2 in the reverse direction to make the two transverse plates 1 5 move away from each other and release the clamped pipeline. Then start motor 3 in the forward direction, reel in the lifting rope 19 again, and bring the side clamping plate 7 out of the foundation pit. Then start motor 4 in the reverse direction to bring the two side clamping plates 7 back into the gantry 1.

[0031] Compared with the related art, the utility model provides a lifting device for installing a pressure pipeline in a narrow space, which has the following beneficial effects:

[0032] The utility model provides a lifting device for installing pressure pipes in narrow spaces. By means of a box body 12 and a one-way screw 13 inside the box body 12, the pressure pipe to be buried can be clamped by two side clamping plates 7, and then the pressure pipe can be lifted by winding up the lifting rope 19. Finally, by rotating the one-way screw 13, the pipe can be extended into the narrow space, and by releasing the lifting rope 19, the pipe can be placed in a pre-buried foundation pit, thereby realizing the lifting operation of the pressure pipe. Moreover, the spacing between the two side clamping plates 7 can be used in combination according to the length of the pipe. At the same time, the height position of the positioning rod 8 can be adjusted, thereby being suitable for the lifting of pressure pipes of different lengths and inner diameters.
