Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0024] Reference Figures 1 to 4 As shown, a slope pressure steel pipe transportation device includes: a traction device 1 located at the top of the slope, a track 2 located on the slope, and a transport trolley 3 located above the track 2; the top of the transport trolley 3 is arc-shaped, and the top of the transport trolley 3 carries the pressure steel pipe 4; the traction device 1 is connected to the pressure steel pipe 4 through a steel wire rope 102; the steel wire rope 102 is parallel to the track 2.

[0025] The track 2 includes: two parallel track bodies 206, a plurality of upright supports 202 arranged along the length of the track bodies 206, a first adjusting device 203 detachably connected to the upright supports 202, and a pad 201 disposed at the bottom of the first adjusting device 203; the upright supports 202 are provided with a plurality of positioning holes, and the first adjusting device 203 is provided with a plurality of limiting holes of the same diameter as the positioning holes, the spacing between adjacent limiting holes being the same as the spacing between positioning holes; the first adjusting device 203 and the upright supports 202 are connected by at least two bolts 205 passing through the positioning holes and limiting holes to prevent rotation between the first adjusting device 203 and the upright supports 202. It should be noted that in this embodiment, the sidewall of the upright support 202 is connected to the sidewall of the track body 206 by bolts 205, and the top of the upright support 202 can rotate along the axis of the bolts 205, that is, the upright support 202 can rotate along the length of the track body 206, ensuring that the upright support 202 is always in a vertical state during installation.

[0026] Preferably, in this embodiment, the traction device 1 is a winch 101. One end of the wire rope 102 is connected to the winch 101, and the other end of the wire rope 102 is divided into two branches. Each branch has an anti-detachment hook, which engages with a lifting lug on the side wall of the pressure steel pipe 4. The lifting lugs are symmetrically welded to the center of the side wall of the pressure steel pipe 4. It should be noted that the anti-detachment hook and lifting lug are not shown in the figure. The anti-detachment hook is a commercially available product, which only needs to prevent the wire rope 102 from detaching from the lifting lug when the winch 101 pulls the pressure steel pipe 4. It should be noted that in this embodiment, the traction device 1 is connected to the pressure steel pipe 4 through the wire rope 102. When the pressure steel pipe 4 is pulled, because the pressure steel pipe 4 has a large enough weight and the friction between the pressure steel pipe 4 and the transport trolley 3 is large enough, the pressure steel pipe 4 will not detach from the transport trolley 3 when pulled by the traction device 1 through the wire rope 102. Example 2

[0027] Based on Example 1, such as Figure 1 and Figure 4 As shown, in this preferred embodiment, the two parallel rail bodies 206 are connected by several crossbeams 207, and several tripod supports 204 are arranged at the bottom of the rail body 206 to improve the stability of the rail body 206. Specifically, the top of the tripod support 204 is provided with a connecting lug, which is parallel to the side wall of the rail body 206 and is connected to the side wall of the rail body 206 by bolts 205.

[0028] Preferably, in this embodiment, the tripod support 204 is detachably connected to the first adjustment device 203. The tripod support 204 is provided with a plurality of positioning holes, and the first adjustment device 203 is provided with a plurality of limiting holes with the same diameter as the positioning holes. The spacing between adjacent limiting holes is the same as the spacing between positioning holes. The first adjustment device 203 and the tripod support 204 are connected by at least four bolts 205 passing through the positioning holes and limiting holes. Each leg of the tripod support is connected to the first adjustment device 203 by at least two bolts 205 passing through the positioning holes and limiting holes to prevent rotation between the first adjustment device 203 and the legs. Example 3

[0029] Based on Example 2, such as Figures 1 to 4 As shown, preferably, in this embodiment, the transport trolley 3 includes: a frame 304, wheels 301 disposed at the bottom of the frame 304, and a trolley panel 305 disposed at the top of the frame 304; the wheels 301 are positioned above the rail body 206; the trolley panel 305 bears the pressure steel pipe 4. In this embodiment, there are four wheels 301, which are respectively disposed at the four corners of the bottom of the frame 304.

[0030] Preferably, in this embodiment, a second adjusting device 303 is provided between the frame 304 and the wheel 301. The second adjusting device 303 includes an upper sleeve connected to the frame 304, a lower sleeve fitted onto the upper sleeve, and a positioning bolt. Positioning holes are provided on both the upper and lower sleeves, and the positioning bolt is fitted into the positioning holes. The second adjusting device 303 allows for a small range of adjustment of the distance and angle between the pressure steel pipe 4 and the track 2, facilitating the parallelism of the wire rope 102 with the track 2 when the pressure steel pipe 4 is pulled. It should be noted that the specific structure of the second adjusting device 303 is not shown in the figure; it only needs to ensure that all four second adjusting devices 303 can be individually extended and retracted.

[0031] Preferably, in this embodiment, a pad is provided above the trolley panel 305. The pad is used to prevent slipping and protect the pressure steel pipe 4. A large wedge block 306 is provided in the gap between the trolley panel 305 and the pressure steel pipe 4 to prevent the pressure steel pipe 4 from swaying left and right during transportation and welding.

[0032] Preferably, in this embodiment, a small wedge block 302 is placed on the rail 206 behind the wheel 301, and the small wedge block 302 limits the transport trolley 3 when it needs to stop.

[0033] When transporting welded pressure steel pipe 4 using this slope pressure steel pipe transport equipment, firstly, a total station is used to lay out the axis of the pressure steel pipe 4 to be installed. Then, based on the laid-out axis, the planar positions of the small winch 101, the upright support 202, and the tripod support 204 are determined. Next, the elevation of the track 2 is laid out according to the designed slope of the pressure steel pipe 4. The height of the upright support 202 is adjusted according to the site terrain to ensure the linearity and consistent angle of the track 2. Then, the rail body 206 and crossbeam 207 on the upper part of the upright support 202 are assembled sequentially to ensure sufficient stability of the assembled track 2. Then, the fabricated transport trolley 3 is hoisted onto the track 2. Finally, the operators hoist the pressure steel pipe 4 onto the transport trolley 3, and transport the pressure steel pipe 4 to its position using the traction device 1 and the track 2. The welder adjusts the horizontal displacement and vertical height of the pressure steel pipe 4 to be welded by adjusting the adjustment device of the transport trolley 3 according to the welding requirements, thereby meeting the operational needs.
