Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It is necessary to point out that the following embodiments are only used to further illustrate the present invention, and should not be interpreted as limiting the protection scope of the present invention. Those of ordinary skill in the art can make some non-essential changes to the following embodiments according to the essence of the present invention. Improvements and tweaks. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as there is no conflict between the other features.

[0034] like Figure 1 to Figure 7 Shown, a kind of trolley with hydraulic lifting platform comprises a base 8 with wheels, a push handle 20 located at one end of the base 8, a liftable platform 9, a lifting mechanism located between the base 8 and the plat...

Abstract

The invention relates to a hydraulic cylinder and a trolley with a hydraulic lifting platform. The trolley comprises a base, a push handle, the liftable platform, a lifting mechanism, the hydraulic cylinder, an oil tank, a manual pump and a hand-operated or foot-operated mechanism capable of driving the manual pump. A first oil circuit is arranged between an oil inlet of the manual pump and the oil tank, a second oil circuit is arranged between an oil outlet of the manual pump and a working chamber of the hydraulic cylinder, a third oil circuit and an oil drain valve are arranged between the working chamber of the hydraulic cylinder and the oil tank, an electric pump, a power source and a start button are arranged on the trolley, a fourth oil circuit is arranged between an inlet of the electric pump and the oil tank, and a fifth oil circuit is arranged between an outlet of the electric pump and the working chamber of the hydraulic cylinder. The hydraulic cylinder and the trolley have the advantages that electric lifting and manual lifting effects can be realized, and the integral trolley with the platform is minimized, is light and is flexible in service places; the manual pump, a motor, a gear pump, the hydraulic cylinder, the oil tank, actuating elements and valve blocks of the oil circuits are highly integrated with one another and can be connected with hydraulic systems without oil pipes.

Description

technical field [0001] The invention relates to a cart with a hydraulic lifting platform, which is highly integrated with a human pump, a motor, a gear pump, a hydraulic cylinder, an oil tank, an actuator, and an oil circuit valve block, so as to realize the connection of a hydraulic system without oil pipes. In particular, it is a trolley with a hydraulic lifting platform that can be lifted by both a human-driven platform and an electric-driven platform, and a hydraulic cylinder that is more suitable for the trolley. Background technique [0002] The cart with hydraulic lifting platform is an excellent tool for carrying goods at work, especially the platform cart with hydraulic lift transmission is an indispensable assistant for the mover. [0003] The existing trolley with a hydraulic lifting platform mainly includes a base with wheels, a push handle located at one end of the base, a liftable platform, a lifting mechanism between the base and the platform, and a mechanism ...
