The following describes an embodiment of the present invention in detail with reference to fig. 1 to 2.

As shown in fig. 1, a dolly with rollers includes: the hydraulic system comprises a steering arm 1, an object bearing arm 2 and a first hydraulic device 3, wherein the first end of the steering arm 1 is connected with the first hydraulic device 3, and the first hydraulic device 3 is also connected with the object bearing arm 2. The first hydraulic device 3 is used for lifting the object bearing arm 2, the steering arm 1 is used for operating the first hydraulic device 3, and the first hydraulic device 3 is controlled to drive the object bearing arm 2 to be lifted or lowered.

The steering arm 1 is also provided with a steering wheel, and the steering wheel can be held by hand to operate the steering arm 1 to move the trolley, such as forward, backward or steering. The steering arm 1 is also provided with a hydraulic handle for controlling the first hydraulic device 3, when the object bearing arm 2 needs to be lifted, the hydraulic handle is gripped, and the steering arm 1 is pressed downwards, so that the object bearing arm 2 can be lifted; when the object bearing arm 2 needs to be lowered, the hydraulic handle is held tightly to enable the first hydraulic device 3 to be decompressed, and the object bearing arm 2 can be lowered.

The trolley with the rollers further comprises: a first object bearing platform 4, a second object bearing platform 5, a second hydraulic device 9 and a lifting operating rod 8. The first object bearing platform 4 is fixedly arranged on the object bearing arm 2, and the second object bearing platform 5 is sleeved above the first object bearing platform 4. Preferably, the first object bearing table 4 is mounted on the object bearing arm 2 by means of bolts or the first object bearing table 4 is welded directly to the object bearing arm 2.

A plurality of rollers are arranged on the first surface of the first object bearing platform 4 and the first surface of the second object bearing platform 5, namely the upper surfaces of the first object bearing platform 4 and the second object bearing platform 5 in fig. 1. The installation direction of the rollers on the first object bearing platform 4 is different from that of the rollers on the second object bearing platform 5, preferably, the rollers on the first object bearing platform 4 are transversely arranged, and the rollers on the second object bearing platform 5 are longitudinally arranged.

The second hydraulic device 9 is used for lifting the first object bearing platform 4 so as to change the relative height between the first object bearing platform 4 and the second object bearing platform 5. When goods need to go up and down the trolley along the longitudinal roller 7, the second hydraulic device 9 drives the second object bearing table 5 to be lifted until the longitudinal roller 7 on the second hydraulic device 9 is higher than the transverse roller 6 on the first object bearing table 4; when goods need to go up and down the trolley along the transverse roller 6, the second hydraulic device 9 releases the pressure of the second object bearing platform 5 and lowers until the longitudinal roller 7 on the second hydraulic device 9 is lower than the transverse roller 6 on the first object bearing platform 4; when the goods are not needed to get on or off the trolley, the second hydraulic device 9 drives the second object bearing table 5 to ascend and descend until the longitudinal rollers 7 on the second object bearing table 5 are consistent with the transverse rollers 6 on the first object bearing table 4 in height. Preferably, the second hydraulic device 9 is a telescopic hydraulic cylinder.

The lifting lever 8 is connected to the second hydraulic device 9 for actuating the second hydraulic device 9. The lifting operation rod 8 is also provided with a pressure relief structure.

In some embodiments, the trolley with rollers further comprises: motor, speed reducer, ball and jacking link mechanism. Be provided with 2 motors on

holding thing arm

2, 2 motors are located the second and hold the below of thing platform 5 and be close to one side of

lift operating lever

8, and 2 motors are for lift operating lever 8 upper and lower symmetry as in figure 2, and the motor all is connected with lift operating lever 8. Each motor is connected with a speed reducer, the speed reducer is connected with a ball screw, and the ball screw is connected with a jacking connecting rod mechanism. The bottom of the jacking link mechanism is screwed or welded on the object bearing arm 2, and the top of the jacking link mechanism is connected to the second object bearing table 5 and used for supporting the second object bearing table 5.

When the lifting operation rod 8 enables the second hydraulic device 9 to drive the second object bearing table 5 to ascend, or the pressure relief structure on the lifting operation rod 8 is operated to enable the second hydraulic device 9 to relieve pressure so as to enable the second object bearing table 5 to descend, the motor can be started at the same time, the motor drives the ball screw through the speed reducer, and then the jacking connecting rod mechanism is driven to play a role in supporting the second object bearing table 5.

According to the embodiment of the utility model, the first hydraulic device 3 raises or lowers the object bearing arm 2 by operating the steering arm 1 to adjust the height of the goods from the ground so as to adapt to loading and unloading places with different heights; in addition, the relative height between the first object bearing platform 4 and the second object bearing platform 5 is adjusted by operating the lifting operating rod 8, so that the goods are loaded and unloaded through the rollers on the first object bearing platform 4 or the second object bearing platform 5, the work of loading and unloading the goods is more labor-saving, and the efficiency is higher.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
