Embodiment Construction

[0015] Such as figure 1 As shown, the hydraulic speed regulating mechanism for the three-dimensional garage of the present invention includes a main oil circuit control mechanism and an auxiliary oil circuit control mechanism connected in series in the hydraulic circuit, and the main oil circuit control mechanism is composed of a main throttle valve connected in series B. The main cut-off valve D is formed, and the auxiliary oil circuit control mechanism is composed of a series-connected auxiliary throttle valve A and an auxiliary cut-off valve C; Valve B is set to throttle down and sub-throttle valve A is set to throttle up. Both the main throttle valve B and the auxiliary throttle valve A are one-way throttle valves, and the main cut-off valve D and the auxiliary cut-off valve C are both two-way cut-off valves.

[0016] The main oil circuit control mechanism and the auxiliary oil circuit control mechanism can be provided with one set, or two or more sets. Such as image 3...

Abstract

The invention relates to a hydraulic speed regulating mechanism used for a stereo garage and an acceleration and deceleration method. The hydraulic speed regulating mechanism used for the stereo garage comprises a main oil line control mechanism connected in a hydraulic loop in series, wherein the main oil line control mechanism is composed of a main throttle valve and a main check valve connected in series; an assistant oil line control mechanism is connected on the main oil line control mechanism in parallel; the assistant oil line control mechanism consists of an assistant throttle valve and an assistant check valve connected in series; the throttle direction of the main throttle valve and the throttle direction of the assistant throttle valve are reverse. The hydraulic oil flow is regulated by controlling the main oil line control mechanism and the assistant oil line control mechanism to realize the variable motion of a vehicle tray, thereby achieving the purpose of enhancing the efficiency of storing and taking vehicles.

Description

technical field [0001] The invention relates to a hydraulic speed regulating mechanism and a lifting speed regulating method for a three-dimensional garage. technical background [0002] Hydraulic three-dimensional parking equipment has the characteristics of noise reduction and stable operation, and has been more and more popularized and applied. Such as Chinese patent application number: 200810015050.1. The invention discloses such a three-dimensional parking device powered by a hydraulic lifter. For another example, the Chinese patent application "Hydraulic Driven Three-dimensional Parking Equipment" with the application number of 2009100050300 discloses a hydraulic three-dimensional parking equipment that adopts a two-way stop valve. control to avoid interference with other hydraulic lifts connected in parallel; in addition, the action of the electronically controlled two-way stop valve is controlled by electromagnetic force, which not only reduces the cost of producti...
