[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and the best embodiment.

[0018] Figure 1-3 A steel pipe transportation device for deep foundation pit steel pipe well construction is shown, including two mobile frames arranged symmetrically in front and back and a connecting rope 7 (hereinafter referred to as the rope) connecting the two mobile frames; the mobile frame includes a tripod, a steel pipe holding structure arranged on the tripod and a universal wheel arranged under the mobile frame.

[0019] The tripod is made up of three angle steels 1 connected together, with each pair of adjacent angle steels connected by triangular connecting steel plates 2. Each angle steel has two bolt holes at its front and rear ends, respectively; the triangular connecting steel plates have corresponding mounting holes. Bolts 5 are used to connect the bolt holes and mounting holes to secure the triangular connecting steel plates and the angle steels.

[0020] In this application, a 40*40*5mm angle steel with a length of 40cm is used as an illustrative example. The triangular angle steel formed as a whole has better stability and does not deform during use.

[0021] The angle steel of the tripod perpendicular to the transport direction is the first angle steel, and the others connected to the first angle steel are the second angle steel and the third angle steel; the clamping structure includes a connecting frame connecting the second angle steel and the third angle steel and two fixed clamping wheels 4 arranged on the connecting piece.

[0022] The first angle steel is also provided with a fixed card wheel 4 at a position corresponding to the fixed card wheel. The fixed card wheels are symmetrically arranged in two groups of four along the central axis of the tripod, which can effectively fix the steel pipes placed on the tripod so that they do not move during transportation and effectively play a fixing role.

[0023] The first angle steel and the connecting frame are equipped with a rope connection ring 6. This U-shaped connection ring 6 connects the two mobile frames, forming a complete steel pipe transport device through the use of a connecting rope 7. The connecting rope 7 is pulled and moved by a handheld traction rope ring 11. The connecting rope has a diameter of no less than 10 mm, and its length can be adjusted to the length of the transported steel pipe. The traction rope is arranged in a circular ring, forming the traction rope ring 11, which further facilitates steel pipe transportation.

[0024] The triangular connecting steel plate is provided with a connecting hole for connecting the universal wheel; the universal wheel includes a rotating shaft 3 connected to the connecting hole, a mounting frame 9 connected to the rotating shaft, a mounting shaft 9 set on the mounting frame and a wheel 10 set on the mounting shaft. The rotating shaft 3 can rotate freely in the connecting hole to realize the rotation of the universal wheel in different directions.

[0025] From the above, it can be seen that the steel pipe transportation device for deep foundation pit steel pipe well construction of the present invention adopts a clamping structure to fix the steel pipe, and adopts a tripod composed of angle steel and universal wheels under the tripod to transport the steel pipe, which saves time and effort and realizes fast and flexible on-site transportation: reducing manpower input; as a preferred form, each mobile frame is provided with 4 fixed clamping wheels to fix the front and rear ends of the steel pipe, making transportation convenient, fast and labor-saving. At the same time, the front and rear two mobile frames can be adjusted according to the length of the steel pipe by ropes. The steel pipe and the rope combine the two mobile frames into a whole, and can be rotated in any direction by universal wheels to meet the transportation requirements within the construction site. The steel pipe transportation device for deep foundation pit steel pipe well construction of the present invention is more suitable for the transportation of steel pipe well pipes of different diameters and long-sized steel pipe well pipes, and has a wide range of applications.
