It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] See also Figure 1 , Figure 1 The schematic diagram of the structure of a pipeline transport vehicle in an embodiment of the utility model is a pipeline transport vehicle, comprising a transport frame 1, wheels 2 are arranged on both sides of the transport frame 1, a load-bearing plate 3 is connected to the upper end of the transport frame 1, and a push rod 4 is connected to the front of the transport frame 1;

[0023] The braking mechanism 5 includes a handbrake handle 51, a brake wire 52, a cylinder 53, a brake end 54 and a brake spring 55; the handbrake handle 51 is connected to the push rod 4, and the handbrake handle 51 is connected to the brake wire 52, the cylinder 53 is arranged on the transport frame 1 and close to the wheel 2, the cylinder 53 is connected to the brake end 54 through the brake spring 55, and the end of the brake wire 52 extends into the cylinder 53 and is connected to the brake end 54.

[0024] In this embodiment, wheels 2 are arranged on both sides of the transport frame 1 to facilitate the movement of the entire transport frame 1. Secondly, a load plate 3 is arranged on the transport frame 1 to facilitate the placement of the pipe body on the load plate 3. The staff can fasten the pipe body to the load plate 3 through an external rope to avoid the pipe body from falling. Secondly, a push rod 4 is arranged on the transport frame 1, and the entire transport frame 1 can be pushed to move by the push rod 4. A hand brake handle 51 is arranged at the end of the push rod 4. A brake wire 52 is connected, and the other end of the brake wire 52 extends into the cylinder 53 and is connected to the brake end 54. The staff holds the handbrake handle 51 tightly to put the brake wire 52 in a tensioned state, thereby pulling the brake end 54 to squeeze the brake spring 55 in the cylinder 53, causing the brake spring 55 to deform. When the staff releases the handbrake handle 51, the brake wire 52 is no longer in a tensioned state, and under the push of the brake spring 55, the brake end 54 is pushed to abut against the surface of the wheel 2, thereby completing the braking.

[0025] In one embodiment, see Figure 2 In order to improve the stability of the transport frame 1, the transport frame 1 includes a transverse plate 11, a vertical plate 12 and a reinforcing rib 13; the vertical plate 12 is fixed to the upper end of the transverse plate 11, and the reinforcing ribs 13 are connected between the two sides of the vertical plate 12 and the transverse plate 11, and the two sides of the transverse plate 11 are connected to the wheels 2 through the axle 14.

[0026] In this embodiment, reinforcing ribs 13 are provided between the transverse plate 11 and the vertical plate 12 to enhance the stability between the transverse plate 11 and the vertical plate 12 and avoid shaking. Secondly, the wheels 2 are connected to both sides of the transverse plate 11 through the axle 14 to facilitate improving the mobility of the entire transport frame 1.

[0027] In one embodiment, see Figure 2 In order to improve the loading effect of the carrying plate 3, the carrying plate 3 includes a fixing rod 31 and a tube support 32; the fixing rod 31 is connected to the vertical plate 12, and the upper end of the fixing rod 31 is movably connected with an arc-shaped tube support 32, and a rubber pad 321 is bonded to the tube support 32; the pushing rod 4 includes a rod body 41; one end of the rod body 41 is connected to the vertical plate 12, and the other end of the rod body 41 is connected to a gripping handle 42.

[0028] In this embodiment, the fixing rod 31 is connected to the vertical plate 12, and the upper end of the fixing rod 31 is rotatably connected to an arc-shaped pipe support 32, which facilitates the angle adjustment of the pipe body. Secondly, the staff can connect the pipe body to the pipe support 32 through an external rope to ensure stability during transportation. Secondly, a rubber pad 321 is provided on the pipe support 32 to protect the pipe body.

[0029] In one embodiment, see Figure 3 and Figure 4 In order to improve the braking efficiency of the brake mechanism 5, a handbrake handle 51 is connected to the rod body 41, and a first hole 411 and a second hole 412 for a brake wire 52 to pass through are respectively opened on the rod body 41. The brake wire 52 passing through the first hole 411 is connected to the handbrake handle 51, and the brake wire 52 passing through the second hole 412 extends into the cylinder 53 and is connected to the brake end 54. A plurality of limiting rings 521 for limiting the brake wire 52 are arranged on the front side of the cross plate 11. The brake end 54 includes a brake slide plug 541 and a rubber sheet 542; one end of the brake slide plug 541 is connected to a brake spring 55, and the end of the brake spring 55 is connected to the inner wall of the cylinder 53, and the side of the brake slide plug 541 facing away from the brake spring 55 is connected to a rubber sheet 542.

[0030] The first hole 411 and the second hole 412 are provided on the rod body 41 to facilitate the brake wire 52 to pass through the rod body 41. One end of the brake wire 52 is connected to the handbrake handle 51 on the rod body 41, and the other end of the brake wire 52 extends into the cylinder body 53 and is connected to the brake slide plug 541. The brake wire 52 located on the cross plate 11 is limited by the limit ring 521 to prevent the brake wire 52 from scattering. When the staff presses the handbrake handle 51, the brake wire 52 is pulled into a tensioned state. At this time, the brake wire 52 pulls the brake slide plug 541 to squeeze the brake spring 55, causing the brake spring 55 to deform, and the brake slide plug 541 drives the rubber sheet 542 to retract into the cylinder body 53. When the staff no longer presses the handbrake, the brake wire 52 is no longer in a tensioned state, and the brake spring 55 pushes the brake slide plug 541 to move outward, and causes the rubber sheet 542 to abut against the wheel 2, thereby completing the braking of the wheel 2.

[0031] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail: the staff places the pipe to be transported on the pipe support 32, and ties the pipe to the pipe support 32 through an external rope. The staff presses the handbrake handle 51, and pulls the brake wire 52 through the handbrake handle 51, so that the brake wire 52 is in a tensioned state. When the brake wire 52 is in a tensioned state, the brake slide plug 541 is pulled to move in the cylinder 53. At this time, the rubber sheet 542 does not abut against the outer periphery of the wheel 2. The staff holds the handle 42 and the rod body 41. The handbrake handle 51 is no longer pressed when the staff needs to stop moving. At this time, the brake wire 52 is no longer in a tensioned state, and the brake spring 55 pushes the brake slide 541 to move outward in the cylinder 53, and prompts the rubber sheet 542 to abut against the outer surface of the wheel 2, thereby braking the wheel 2, enhancing the stability of the device when it is stagnant, and avoiding displacement. It should be noted that the handbrake handle 51 is a bicycle brake handle available on the market.

[0032] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
