Problems solved by technology

[0003] Due to the fixed wheel structure of the front wheels, the steering of the vehicle is inflexible and the turning radius is large
In the case of close-distance operation, it is impossible to quickly approach the loading and unloading station, which affects the construction speed
Especially when working in areas with narrow working space, this phenomenon is more prominent, seriously affecting the working efficiency

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 As shown, the manual hydraulic truck includes handle 1, oil cylinder body 2, large piston rod 31, small piston rod 32, support body 4, rear wheel 5, rear connecting rod 6, car body 7, front connecting rod 8, front Support body 9 ; the vehicle body 7 is hinged to the support body 4 through the rear connecting rod 6 , and the front support body 9 is hinged to the vehicle body 7 through the front connecting rod 8 .

[0018] The inside of the oil cylinder body 2 is actually a hydraulic jack, and a large oil cylinder and a small oil cylinder are arranged. The large oil cylinder and the small oil cylinder are connected. , one end of the small piston rod 32 is connected with the small oil cylinder, and the other end stretches out from the top of the oil cylinder body 2. When the external force drives the small piston rod 32 an...

Abstract

The invention discloses a manual hydraulic carrying vehicle. The manual hydraulic carrying vehicle comprises a handle, an oil cylinder body, a large piston rod, a small piston rod, a supporting base body, a rear wheel, a rear connection rod, a vehicle body, a front connection rod and a front support. The front support comprises a support body, balls, rolling balls and a gland. The support body is provided with spherical-surface grooves. The rolling balls are put in the spherical-surface grooves. The multiple balls are put between each spherical-surface groove and the corresponding roll ball. Round holes are formed in the positions, corresponding to the rolling balls, of the gland. The gland is connected with the support body through screws. The balls and the rolling balls are limited in the spherical-surface grooves, and a part of the rolling balls makes contact with the ground through the gland. According to the manual hydraulic carrying vehicle, the vehicle running direction can be freely changed along with the driving force direction through the novel driving wheel structure, the output of tractive effort of a consignment person during vehicle steering is reduced, the time and effort are saved, and the operation strength is reduced.

Description

technical field [0001] The invention relates to a manual hydraulic transport vehicle, which belongs to the technical field of loading and unloading equipment. Background technique [0002] In the existing manual hydraulic pallet truck, the rear wheel is a driving wheel, which also has a steering function; the front wheel is a driven wheel, which bears the main weight of the cargo. [0003] Since the front wheels adopt a fixed wheel structure, the steering of the vehicle is inflexible and the turning radius is large. In the case of close-distance operation, it is impossible to quickly approach the loading and unloading station, which affects the construction speed. This phenomenon is more prominent especially when working in areas with narrow working space, which seriously affects the working efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a manual hydraulic transport vehicle. By improving the steering mechanism, the steer...
