[0045] Please refer to the attached document. Figures 1-8This application illustrates a portable pipe hoisting and transport vehicle provided in an embodiment of the present application, used for transporting steel pipes, which includes: a steering front wheel structure 1, a vehicle body structure 3, and a hoisting structure 2.

[0046] The bottom of the steering front wheel structure 1 is provided with a front wheel assembly 1a, and the bottom of the vehicle body structure 3 and near the rear end are provided with a rear wheel assembly 3a. The front end of the vehicle body structure 3 is rotatably mounted to the steering front wheel structure 1 through a vehicle body connecting shaft. The steering front wheel structure 1 and the vehicle body structure 3 are supported by the front wheel assembly 1a and the rear wheel assembly 3a. The steering front wheel structure 1 can rotate relative to the vehicle body structure 3. With the help of an external traction vehicle, the portable pipe hoisting and transport vehicle can be moved. The lifting structure 2 is fixedly installed on the top of the vehicle body structure 3 for lifting and fixing steel pipes.

[0047] When in use, the lifting structure 2 lifts and fixes the steel pipe, and then the front wheel structure 1, the vehicle body structure 3 and the lifting structure 2 are pulled and moved as a whole to achieve the purpose of transporting the steel pipe.

[0048] In one embodiment, the vehicle body structure 3 includes: a frame vehicle body 301, a vehicle body traction beam 302, a socket member 303, and a limiting crossbeam 304.

[0049] The rear opening of the frame body 301 has a transverse U-shaped structure, which allows pipes of different lengths to be lifted upwards from the middle of the frame body 301 (the rear opening can accommodate steel pipes longer than the frame body 301). The vehicle body traction beam 302 is fixedly installed on the inner side of the frame body 301, and the vehicle body traction beam 302 is close to the front end of the frame body 301. The vehicle body traction beam 302 has a double crossbeam structure, and both ends are fixed by welding. A plug-in component 303 is fixedly installed in the middle of the vehicle body traction beam 302. The plug-in component 303 has a circular structure and is used to install the vehicle body connecting shaft. The top of the limiting crossbeam 304 has an arc-shaped positioning port 304a. The limiting crossbeam 304 is fixedly installed on the inner side of the vehicle body traction beam 302 by bolts and pins 305. There are two limiting crossbeams 304, one close to the rear end of the frame body 301 and the other close to the vehicle body traction beam 302.

[0050] When in use, both limiting beams 304 are disassembled, and the portable pipe hoisting and transport vehicle is moved to a suitable position so that the steel pipe is located inside the frame vehicle body 301. The steel pipe can be from the rear end of the frame vehicle body 301, and the front end of the steel pipe needs to be completely inside the frame vehicle body 301. Then, the steel pipe is lifted using the lifting structure 2, and then the two limiting beams 304 are installed, with the steel pipe placed above the two limiting beams 304.

[0051] In one embodiment, the steering front wheel structure 1 includes: a first frame 101, a traction rod 102, and a traction diagonal rod 103.

[0052] The front wheel assembly 1a is installed at the bottom of the first frame 101. A second insertion hole is fixedly installed on the first frame 101. The second insertion hole corresponds to the insertion hole 303 and is used to install the vehicle body connecting shaft. One end of the tow rod 102 is fixedly connected to the first frame 101. The other end of the tow rod 102 is fixedly provided with a main tow ring 102a. The main tow ring 102a corresponds to the towing part of the tractor. A traction diagonal rod 103 is also fixedly connected between the tow rod 102 and the first frame 101. The traction diagonal rod 103 is used to increase the structural strength of the tow rod 102.

[0053] In one embodiment, the lifting structure 2 includes: a gantry-type lifting support assembly 201 and a vehicle body longitudinal beam 202. The gantry-type lifting support assembly 201 is fixedly installed on the frame vehicle body 301. Multiple sets of gantry-type lifting support assemblies 201 are provided, generally designed as two sets. The vehicle body longitudinal beam 202 is fixedly connected between adjacent sets of gantry-type lifting support assemblies 201 to increase the stability of the vehicle body longitudinal beam 202.

[0054] In one embodiment, the portal frame lifting support assembly 201 includes: a vehicle body upright 201b, a lifting upright 201a, a vehicle body bracket 201c, a jack 201d, a ratchet limiter 201e, and a lifting belt (not shown in the figures).

[0055] The bottom end of the vehicle body upright 201b is fixedly connected to the frame vehicle body 301, the bottom end of the lifting upright 201a is slidably connected to the vehicle body upright 201b, the side of the vehicle body upright 201b is fixedly installed with a vehicle body bracket 201c, and the top of the vehicle body bracket 201c is fixedly installed with a jack 201d; the vehicle body upright 201b, the lifting upright 201a, the vehicle body bracket 201c, and the jack 201d are all symmetrically arranged in two sets, a crossbar is fixedly installed between the top ends of the two sets of lifting uprights 201a, the top telescopic end of the jack 201d is fixedly connected to the crossbar, and a ratchet limiter 201e is fixedly installed at the bottom of the crossbar.

[0056] The horizontal frame moves up and down by jack 201d, which in turn moves the lifting pole 201a up and down. The lifting pole 201a slides relative to the vehicle body pole 201b, which guides the up and down movement and ensures the smooth movement of the horizontal frame.

[0057] During hoisting, the hoisting sling is connected to the ratchet limiter 201e. The user binds the hoisting sling to the steel pipe, and then connects the hoisting sling to the ratchet limiter 201e, relying on the ratchet limiter 201e to tension the hoisting sling.

[0058] In one embodiment, an arc-shaped limiting steel plate 201f is fixedly connected to the bottom of the frame. The arc-shaped limiting steel plate 201f is used to protect the ratchet limiter 201e and prevent the steel pipe from moving upward and hitting the ratchet limiter 201e.

[0059] In one embodiment, two ratchet limiters 201e are mounted on each crossbar, such as... Figure 8 The ratchet limiter 201e shown has a rotating part. One end of the rotating part is provided with a porous cylindrical part that facilitates rotation by using a force-applying rod, and the other end is a ratchet structure. The ratchet limiter 201e is a commonly used tool for tightening wires, and will not be described in detail here.
