Description
Technical field
This utility model relates to mechanical engineering technical field, is specifically related to a kind of stereo garage elevator structure based on electrohydraulic proportion technology.
Background technology
Along with China's economic development, parking difficulty outstanding problem, multi-storied garage is the effective way solving this problem.Wherein, vertical lift type multi-storied garage quickly grows because its land utilization ratio is high, and its elevating mechanism is the moving component that this garage is most crucial, and its performance directly affects whole efficiency and the cost in garage.Current elevating mechanism technology comes from elevator industry, and commonly used AC asynchronous motor is as driving element, and this type of drive no doubt has technology maturation, stable performance, controls relatively reliable advantage, but it is little also to have power-weight ratio, anti-overload ability is more weak, the shortcoming that start-stop impact is bigger.And the type of drive hydraulic-driven that another kind commonly uses in the industry, because of its technology maturation, control reliable, the features such as power-weight ratio is big, and anti-overload ability is strong, operates steadily, compact conformation, it is adaptable to the driving of high-performance elevating mechanism.Owing to Garage lifting mechanism requires have higher positioning precision, hydraulic drive mechanism based on electrohydraulic proportion technology can be used.
Utility model content
The purpose of this utility model is the deficiency for current prior art, it is provided that a kind of stereo garage elevator structure based on electrohydraulic proportion technology.
This utility model be the technical scheme is that a kind of stereo garage elevator structure based on electrohydraulic proportion technology, it is characterised in that: include hydraulic system and elevating mechanism；Described hydraulic system includes hydraulic cylinder, and hydraulic cylinder bottom connects an electric control one-way valve, and the other end of electric control one-way valve divides two-way, and proportional throttle valve of leading up to is connected with fuel tank, and check valve of separately leading up to is connected with two position three-way valve；The two position three-way valve other end divides three tunnels, and the first via is connected with fuel tank by dosing pump, filter, and the second tunnel is connected with fuel tank by overflow valve, and the 3rd tunnel is connected with fuel tank by two position two-way valve, and at three tunnel shuntings, connection has a Pressure gauge；The thermometer that also includes being connected with fuel tank, liquidometer, air filter；Described elevating mechanism uses assembly pulley one track cable mechanism.
The beneficial effects of the utility model are: it is high that this utility model has control accuracy, drive simplicity, and contamination resistance is strong, and the advantages such as the pressure loss is little can meet the requirement of relatively high control precision at lower cost.

Label title in figure: (1) fuel tank, (2) two position two-way valve, (3) Pressure gauge, (4) overflow valve, (5) filter, (6) dosing pump, (7) two position three-way valve, (8) check valve, (9) electric control one-way valve, (10) hydraulic cylinder, (11) proportional throttle valve, (12) thermometer, (13) liquidometer, (14) air filter.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail explanation.
A kind of stereo garage elevator structure based on electrohydraulic proportion technology, as shown in Figure 1, it is characterised in that: include hydraulic system and elevating mechanism；Described hydraulic system includes hydraulic cylinder (10), hydraulic cylinder (10) bottom connects an electric control one-way valve (9), the other end of electric control one-way valve (9) divides two-way, proportional throttle valve (11) of leading up to is connected with fuel tank (1), and check valve (8) of separately leading up to is connected with two position three-way valve (7)；Two position three-way valve (7) other end divides three tunnels, the first via is connected with fuel tank (1) by dosing pump (6), filter (5), second tunnel is connected with fuel tank (1) by overflow valve (4), 3rd tunnel is connected with fuel tank (1) by two position two-way valve (2), and at three tunnel shuntings, connection has a Pressure gauge (3)；The thermometer (12) that also includes being connected with fuel tank (1), liquidometer (13), air filter (14)；As in figure 2 it is shown, described elevating mechanism uses assembly pulley one track cable mechanism.It is high that this utility model has control accuracy, drives simplicity, and contamination resistance is strong, and the advantages such as the pressure loss is little can meet the requirement of relatively high control precision at lower cost.
This utility model uses a kind of structure changes Metering Flow Control Circuits, in the ascent stage, uses by-pass throttle speed control loop, improves system effectiveness, reduces capacity loss；And in descending branch, become meter out speed control loop, it is ensured that smooth decreasing, reduces parking stall impulsion.Specifically hydraulic schematic diagram is as shown in Figure 1: hydraulic system is driven by dosing pump (6), and overflow valve (4) is used for system unloaded as safety valve setting system maximum pressure, two position two-way valve (2)；When hydraulic cylinder (10) drives vehicle-containing to rise, two position three-way valve (7) obtains current potential in right position, hydraulic oil enters hydraulic cylinder (10) through check valve (8), electric control one-way valve (9), promoting piston stroking upward, proportional throttle valve (11) constitutes by-pass throttle speed control loop；When parking stall keeps aloft, two position three-way valve (7) dead electricity, it is positioned at left position, hydraulic oil is sealed in oil pocket by electric control one-way valve (9), and two position two-way valve (2) obtains electric, dosing pump (6) off-load；When hydraulic cylinder (10) drives vehicle-containing to decline, electric control one-way valve (9) obtains electric, open check valve (8), hydraulic oil flows back to fuel tank (1) through electric control one-way valve (9) and proportional throttle valve (11), constitutes meter out speed control loop.
Owing to the lifting of Garage lifting mechanism is to liking automobile, needing to use bigger carrier loader platform (about 6mX2.8m), the biggest platform needs to solve its unbalance stress, platform deforms, lifting the technical problems such as unstable, therefore, this utility model uses multiple spot to hang lifting method and solves this problem.Concrete grammar is as shown in Figure 2: assembly pulley uses four pulley parallel connections, simultaneously drive four steel wire ropes, then through assisting fixed pulley to change direction and the position of each steel wire rope respectively, make steel wire rope hang 4 points of liter vehicle-containing respectively, ensureing vehicle-containing uniform force with this, lifting is steadily.
The above, be only preferred embodiment of the present utility model, not impose any restrictions this utility model, every according to this utility model technical spirit, above example is made any simple modification, change, still fall within protection domain of the present utility model.
