Therefore, the distance between the first pushing cylinder 601 and the third pushing cylinder 603 is the same as the distance between the second pushing cylinder 602 and the fourth pushing cylinder 604, so that when unit supports positioned on different sides of a roadway are conveyed, the unit supports can be placed at the positions of the opposite centers of the placing bottom plates 10, and the rollover risk is reduced.
In some embodiments, as shown in fig. 1, the lift cylinders include a first lift cylinder 501, a second lift cylinder 502, a third lift cylinder 503, and a fourth lift cylinder 504, the first lift cylinder 501 and the second lift cylinder 502 are located on the front side of the first support frame 201 and connected to the first support frame 201, the first lift cylinder 501 and the second lift cylinder 502 are arranged at intervals in the width direction of the placement base plate 10, the third lift cylinder 503 and the fourth lift cylinder 504 are located on the rear side of the second support frame 202 and connected to the second support frame 202, and the third lift cylinder 503 and the fourth lift cylinder 504 are arranged at intervals in the width direction of the placement base plate 10.
Therefore, the first lift cylinder 501, the second lift cylinder 502, the third lift cylinder 503 and the fourth lift cylinder 504 can form four supporting points, so as to improve the stability of the lift cylinders to the supporting frame and the placing bottom plate 10.
Further, the first lift cylinder 501 is opposed to the third lift cylinder 503 in the front-rear direction, and the second lift cylinder 502 and the fourth lift cylinder 504 are opposed to each other in the front-rear direction, to further improve the support stability of the lift cylinders.
In some embodiments, as shown in fig. 3, the placing base plate 10 has a first inclined surface 101 and a second inclined surface 102 opposite to each other in the width direction thereof, the first inclined surface 101 extends obliquely from bottom to top toward a direction close to the second inclined surface 102, and the second inclined surface 102 extends obliquely from bottom to top toward a direction close to the first inclined surface 101. Therefore, when the pushing cylinder pushes and pulls the unit bracket, the unit bracket can move to the placing bottom plate 10 or separate from the placing bottom plate 10 along the first inclined surface 101 or the second inclined surface 102.
It can be understood that the inclination of the first inclined plane 101 and the second inclined plane 102 can reduce the moving difficulty of the unit bracket, avoid the interference between the edge of the placing bottom plate 10 and the unit bracket, and facilitate the transportation.
In some embodiments, as shown in fig. 4, the unit rack truck 1 further includes a head 70, the head 70 being located at a front side of the prevention floor, the head 70 being connected with the support frame.
