DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. 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.

[0026] In order to solve the technical problem of high labor intensity in manually bending over to lift the lamp poles onto a transport device, the utility model provides a portable lamp pole transport vehicle, which can avoid manual bending over to lift the lamp poles and alleviate labor intensity.

[0027] It should be noted that the portable lamp pole transport vehicle described in the utility model is used for but not limited to lamp poles, etc. For the convenience of explanation, in the utility model, only a portable lamp pole transport vehicle applied to lamp poles is used as an example for explanation. The principle of applying a portable lamp pole transport vehicle to other types of equipment is essentially the same as the principle applied to lamp poles, which will not be repeated here.

[0028] See also Figure 1 - Figure 5 ,in Figure 1This is a structural schematic diagram of a portable light pole transport vehicle in one embodiment of the utility model, a portable light pole transport vehicle includes a first trailer 1 and a second trailer 2, the first trailer 1 includes a first shaft 11, a pair of first rollers 12, a first U-shaped bracket 13 and a pull rod 14, the two first rollers 12 are installed at both ends of the first shaft 11, one end of the pull rod 14 is fixedly connected to one side of the first shaft 11, the bottom of the first U-shaped bracket 13 is rotatably connected to the top of the first shaft 11, the first U-shaped bracket 13 is used to support the bottom end of the light pole, the second trailer 2 is connected to the first shaft 11, and the second trailer 2 is used to support the top of the light pole.

[0029] In this embodiment, the bottom of the first U-shaped bracket 13 is rotatably connected to the top of the first shaft 11, so that the end of the first U-shaped bracket 13 can be inserted into the gap between the lamp pole 3 and the ground by self-rotation (since the bottom end of the lamp pole 3 is installed with a connecting block 31, there will be a certain gap between the lamp pole 3 and the ground), and then the first U-shaped bracket 13 is tilted by the pull rod 14, so that the bottom end of the lamp pole 3 is embedded in the first U-shaped bracket 13, and the second trailer 2 is used to lift the top of the lamp pole, so that the lifting of the lamp pole 3 is completed. The entire transportation process does not require the staff to manually grab the lamp pole, which effectively reduces the labor intensity of carrying the lamp pole 3.

[0030] First, when lifting the lamp pole 3, the first U-shaped bracket 13 is rotated so that the surface of the pull rod 14 and the surface of the first U-shaped bracket 13 are coplanar with each other; then, the first shaft rod 11 is rotated by the pull rod 14, and the first shaft rod 11 drives the first U-shaped bracket 13 to rotate in the direction close to the ground, so that the end of the first U-shaped bracket 13 away from the pull rod 14 contacts the ground; then, the first trailer 1 is pushed, the first roller 12 rotates, and the end of the first U-shaped bracket 13 contacting the ground is inserted into the gap between the bottom end of the lamp pole 3 and the ground; then, the first shaft rod 11 is rotated by the pull rod 14, and the first shaft rod 11 drives the first U-shaped bracket 13 to rotate in the direction away from the ground, and at the same time, the first U-shaped bracket 13 rotates until the first U-shaped bracket 13 returns to the initial state (initial state: the surface of the first U-shaped bracket 13 is perpendicular to both the ground and the surface of the pull rod 14); finally, under the abutment of the first U-shaped bracket 13 and the connecting block 31 at the bottom end of the lamp pole 3, the first trailer 1 drives the lamp pole 3 to move.

[0031] In one embodiment, see Figure 1 - Figure 3 The top of the first shaft rod 11 is fixedly connected to a support rod 111 , a blind hole 1111 is opened on the top of the support rod 111 , and the bottom of the first U-shaped bracket 13 is fixedly connected to a rotating rod 131 , which is rotatably sleeved in the blind hole 1111 .

[0032] In this embodiment, the first U-shaped bracket 13 has a rotation function by rotating the rotating rod 131 and rotating it in the blind hole 1111. When the lamp pole 3 needs to be lifted, the first U-shaped bracket 13 is rotated so that the two ends of the first U-shaped bracket 13 are located on both sides of the first shaft 11 (that is, the surface where the pull rod 14 is located is coplanar with the surface where the first U-shaped bracket 13 is located). The staff can rotate the first shaft 11 so that the end of the first U-shaped bracket 13 away from the pull rod 14 touches the ground, which is convenient for pushing the first roller 12 so that the end touching the ground is inserted into the gap between the bottom end of the lamp pole 3 and the ground.

[0033] In one embodiment, see Figure 2 The side wall of the rotating rod 131 is fixedly connected with a first tooth 1311 , the inner wall of the blind hole 1111 is fixedly connected with a second tooth 1112 , and the first tooth 1311 is meshed with the second tooth 1112 .

[0034] In this embodiment, when the first U-shaped bracket 13 needs to be inserted into the gap between the lamp pole 3 and the ground, the first tooth 1311 engages with the second tooth 1112, so that the first U-shaped bracket 13 cannot rotate, which facilitates lifting the lamp pole 3 after inserting into the gap between the lamp pole 3 and the ground, and avoids the first U-shaped bracket 13 from rotating freely and being unable to lift the lamp pole 3.

[0035] In one embodiment, see Figure 3 - Figure 5 A protrusion 1113 is fixedly connected to the top of the second tooth 1112 .

[0036] In this embodiment, the function of the protrusion 1113 is to prevent the rotating rod 131 from being separated from the blind hole 1111 , thereby ensuring the normal rotation of the first U-shaped bracket 13 .

[0037] In one embodiment, see Figure 5 A spring 1312 is provided at the bottom of the second tooth 1112 . The spring 1312 is located in the blind hole 1111 and sleeved on the side wall of the rotating rod 131 .

[0038] In this embodiment, when there is no need to carry the lamp pole 3, the first U-shaped bracket 13 is not under pressure, and the second tooth 1112 is supported by the spring 1312 to always engage with the first tooth 1311, so that the first U-shaped bracket 13 cannot rotate, which is convenient for the staff to insert the first U-shaped bracket 13 into the gap between the lamp pole 3 and the ground by operating the pull rod 14; after picking up the lamp pole 3, the first U-shaped bracket 13 descends due to the pressure of the lamp pole 3, the spring 1312 is compressed, and the first tooth 1311 is disengaged from the second tooth 1112, so that the first U-shaped bracket 13 can rotate freely, which is convenient for transportation.

[0039] In one embodiment, see Figure 3Reinforcing ribs 112 are fixedly connected to opposite sides of the support rod 111 .

[0040] In this embodiment, the function of the reinforcing ribs 112 is to make the support rod 111 more supportive, so as to prevent the light pole 3 from being too heavy and crushing the support rod 111 .

[0041] In one embodiment, see Figure 2 , both ends of the first U-shaped bracket 13 are chamfered.

[0042] In this embodiment, the two ends of the first U-shaped bracket 13 are chamfered to facilitate the first U-shaped bracket 13 to lift the lamp pole 3 by being inserted into the gap between the lamp pole 3 and the ground.

[0043] In one embodiment, see Figure 2 A non-slip pad 132 is fixedly connected to the top of the first U-shaped bracket 13 .

[0044] In this embodiment, the anti-skid pad 132 is made of rubber material to increase the friction between the side wall of the lamp pole 3 and the first U-shaped bracket 13 to prevent the lamp pole 3 from slipping during transportation.

[0045] In one embodiment, see Figure 3 The end of the pull rod 14 away from the first trailer 1 is fixedly connected with a handle 141.

[0046] In this embodiment, the function of the handle 141 is to facilitate the staff to operate the pull rod 14 with both hands, so that it is easier for the first U-shaped bracket 13 to lift the lamp pole 3.

[0047] In one embodiment, see Figure 1 The second trailer 2 includes a second axle 21, a pair of second rollers 22, a second U-shaped bracket 23, a second hinge block 24 and a traction rod 25. The two second rollers 22 are installed at both ends of the second axle 21. The bottom of the second U-shaped bracket 23 is fixedly connected to the top of the second axle 21. The second hinge block 24 is fixedly connected to one side of the second axle 21. The side of the first axle 11 away from the pull rod 14 is fixedly connected with the first hinge block 113. The two ends of the traction rod 25 are hinged to the first hinge block 113 and the second hinge block 24 respectively.

[0048] In this embodiment, both ends of the traction rod 25 are in a barb shape, and the staff can select a traction rod 25 of appropriate length according to the length of different lamp poles 3, which has wider applicability; the first hinge block 113 and the second hinge block 24 are arranged opposite to each other, and the first hinge block 113 and the second hinge block 24 are both provided with through holes, so that the first trailer 1 and the second trailer 2 can be connected by inserting the two ends of the traction rod 25 into the two through holes, making the assembly process more convenient.

[0049] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0050] First, when lifting the lamp pole 3, press the first U-shaped bracket 13 to separate the first tooth 1311 from the second tooth 1112, rotate the first U-shaped bracket 13 to make the surface of the pull rod 14 and the surface of the first U-shaped bracket 13 coplanar with each other, then release the pressure, and under the action of the spring 1312, the first U-shaped bracket 13 rises, and the first tooth 1311 is engaged with the second tooth 1112; then, rotate the first shaft rod 11 by operating the pull rod 14, and the first shaft rod 11 drives the first U-shaped bracket 13 to rotate in a direction close to the ground, so that the end of the first U-shaped bracket 13 away from the pull rod 14 contacts the ground; then, push the first trailer 1, the first roller 12 rotates, and the end of the first U-shaped bracket 13 contacting the ground is inserted into the bottom end of the lamp pole 3 and the ground The gap between the two ends; then, the first shaft rod 11 is rotated by operating the pull rod 14, and the first shaft rod 11 drives the first U-shaped bracket 13 to rotate in the direction away from the ground until the first U-shaped bracket 13 completely carries the lamp pole 3. At the same time, after the first U-shaped bracket 13 is subjected to the pressure of the lamp pole 3, the first tooth 1311 is separated from the second tooth 1112, and the spring 1312 is always in a compressed state, so that the first U-shaped bracket 13 can rotate with the transportation of the lamp pole 3; finally, the top end of the lamp pole 3 is manually lifted to the second U-shaped bracket 23, and the first trailer 1 and the second trailer 2 are connected by the traction rod 25. Under the abutment of the first U-shaped bracket 13 and the connecting block 31 at the bottom end of the lamp pole 3, the first trailer 1 and the second trailer 2 drive the lamp pole 3 to move.
