The manual hydraulic mechanism 4 comprises a hydraulic cylinder 41 which is arranged on the beam rod 12 and used for driving the connecting plate 33, a control handle 43 used for driving the hydraulic cylinder 41 is arranged on the beam rod 12, the manual hydraulic mechanism 4 can drive the carrying bracket 3 to lift or descend, and the existing manual hydraulic forklift structure can be referred to for the structure that the control handle 43 drives the hydraulic cylinder 41 to jack up the connecting plate 33. The rolling assembly 2 comprises two stabilizing wheel sets 21 and a connecting shaft 22 for connecting the two stabilizing wheel sets 21; the stable wheelset 21 includes the fixing base 211 with frame 1 fixed connection, be provided with the spout 212 that is oval in shape in the fixing base 211, slidable mounting has the even slider 213 in three interval in the spout 212, fixedly connected with and fixing base 211 vertically back shaft 214 on the slider 213, the one end that fixing base 211 was kept away from to back shaft 214 is provided with roller mechanism, roller mechanism can be runner 215, runner 215 rotates and installs on back shaft 214, be provided with two sprocket 218 that can the pivoted on the fixing base 211, it has chain 219 to twine between two sprocket 218, evenly install three otic placode 2191 on the chain 219, otic placode 2191 and back shaft 214 fixed connection.

The oval shape means a shape in which the middle part is rectangular and both ends are respectively connected with a semicircle, and is also called a runway shape because the shape is similar to a runway. The distance between two adjacent sliders 213 is smaller than the length distance of the straight portion of the oval-shaped sliding groove 212, the straight portion refers to one side of the rectangle, and the distance between two adjacent sliders 213 refers to the distance along the sliding groove 212, not the straight distance between two sliders 213. The supporting shaft 214 is sleeved with a limiting gear 216 capable of rotating, the fixing seat 211 is provided with a kidney-shaped insection 217 matched with the sliding groove 212, and the limiting gear 216 is meshed with the insection 217.

By arranging the stabilizing wheel set 21, when the present invention meets the obstacle 6 with a load, since the wheels 215 abut against the obstacle 6, the frame 1 is pushed slightly, as shown in fig. 7, the sliding block 213 can move in the sliding slot 212, and simultaneously, under the action of the chain 219, each wheel 215 will maintain a distance between each other, all the wheels 215 will rotate circularly along the sliding slot 212, as shown in fig. 8, when the wheels 215 rotate a certain distance along the sliding slot 212, the rest of the wheels 215 pass over the obstacle 6 and gradually contact the ground, and when the wheels 215 alternately contact the ground, the height position of the fixed seat 211 is not changed, and finally, the wheels 215 abutting against the obstacle 6 will gradually rise and finally pass over the obstacle 6. In the whole process of crossing the obstacle 6, the relative distance between the fixed seat 211 and the ground is not changed, and the carrying bracket 3 is always kept parallel to the ground, so that the invention ensures that the carrying bracket 3 stably crosses the obstacle 6, simultaneously realizes labor-saving crossing of the obstacle 6 without bumping, keeps the stability in the carrying process, solves the problem that the vehicle body for carrying goods must be laboriously lifted to cross the obstacle when the traditional carrying tool encounters the obstacle, and avoids the problem that the goods are inclined, dropped and even broken due to bumping when the goods are carried to cross the obstacle 6.

Specifically, the connecting shaft 22 is rotatably mounted on the side wall of the frame 1, and both ends of the connecting shaft 22 are respectively connected with the chain wheels 218 of the two adjacent stabilizing wheel sets 21 through a pair of bevel gears. By arranging the connecting shaft 22 and the two pairs of bevel gears, when the chain wheel 218 in one of the stabilizing wheel sets 21 rotates, the chain wheel 218 in the other stabilizing wheel set 21 can be driven to synchronously rotate, so that the relative distance between the two stabilizing wheel sets 21 and the rotating wheel 215 in contact with the ground is kept unchanged, and the four stabilizing wheel sets 21 can provide enough and stable supporting area.
