Description
Technical field
The utility model relates to fork truck field, especially relates to a kind of fork truck speed-limiting control device.
Background technology
The speed of fork truck in traveling process lacks control and easily causes safety misadventure, in fork truck power system, by electronic pump, the supply of oil plant is controlled, forklift operator personnel can only carry out according to self judgment the restriction of speed, cannot accept the restriction of external factor, this control for risk is totally unfavorable.
Intellectuality is the development tendency in fork truck field, for the control of fork truck speed, need to examine the factor of operating personal equally, how under the prerequisite that does not increase operating personal work load, to improve intellectuality that fork truck speed controls and be our technical issues that need to address.
Utility model content
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of and can realize the intelligent fork truck speed-limiting control device of controlling of fork truck speed.
To achieve these goals, the utility model adopts following technical scheme:
Fork truck speed-limiting control device, is characterized in that, comprising:
Be installed on forklift gear-box/forklift front bridge and for surveying the speed feedback element of fork truck speed;
For the control element of the speed signal of inbound pacing feedback element, its electronic pump that is electrically connected on fork truck power system with and/or the automatic brake system of fork truck;
For the parameter input module of input speed limit value, it is connected in control element.
As further improvement of the utility model is, described speed feedback element is speed sensor.
As further improvement of the utility model is, described control element is micro controller system.
As further improvement of the utility model is, also comprise the speed state display module being connected with control element.
As further improvement of the utility model is, also comprise the telltale being connected with control element.
As further improvement of the utility model is, described telltale is buzzer phone/alarm lamp.
As further improvement of the utility model is, described speed state display module is LCD/LED read-out.
As further improvement of the utility model is, described parameter input module is keyboard.
Compared with prior art, the utlity model has following beneficial effect:
(1) this fork truck speed-limit device can carry out actv. control to fork truck running velocity under the control of operating personal, concrete speed limit can be by automatically performing speed limit instruction after control panel input control device, forklift operator personnel cannot surpass speed limit by the speed of fork truck, and this is conducive to the safety and stability of fork truck work.
(2) speed sensor setting and change speed gear box are comparatively desirable selections, for cannot be the change speed gear box installation rate sensor in the situation that, still can select forklift front bridge to install, for later stage repacking and the maintenance of fork truck, play positive role, not be limited to fork truck supplier's restriction.
(3) cost of package unit is lower, can actv. improves the intelligent level of fork truck.
Accompanying drawing explanation
Fig. 1 is the block diagram representation of fork truck speed-limiting control device.
The specific embodiment
Below in conjunction with embodiment, specifically set forth this fork truck speed-limiting control device.
The implication of this case "/" is "or".
Fork truck speed-limiting control device, it comprises: the control element of speed feedback element, inbound pacing feedback element information, the parameter input module of inputting for receiving parameter, wherein, the electronic pump of the power system of control element and fork truck interconnects, this control element is controlled electronic pump for the fuel feeding size of fork truck by acquisition speed feedback element information, and then controls fork truck and advance in the speed range of regulation.
For the supplier of fork truck, can before dispatching from the factory, directly speed feedback element be installed on to the change speed gear box of fork truck, this acquisition of information for fork truck speed is most important.
In the situation that downstream manufacturers cannot be installed on change speed gear box by speed feedback element, speed feedback element is installed on to forklift front bridge and also allows, this will make this fork truck speed-limiting control device no longer be limited to any fork truck type of any supplier.
Be well known that in fork truck power system, electronic pump controls for the size of fuel feeding the speed that has directly determined forklift-walking, for electronic pump actv., control and can directly control the speed of fork truck, for fork truck, the control element that is installed on operator's compartment comes the speed signal of inbound pacing feedback element to be absolutely necessary, the speed of obtaining when speed feedback element conducts to control element by this signal higher than preset value, by control element, send signal to electronic pump, thereby reduce the delivery quality for fork truck, thus by fork truck Speed Reduction within limited range.
Referring to Fig. 1, the figure shows an embodiment of fork truck speed-limiting control device, wherein, the speed feedback element that is installed on forklift front bridge is selected speed sensor 1, and the speed sensor of acquisition speed information transfers to control element 2 by speed signal, this control element is usingd micro controller system as control axis, after the information that acquisition speed limit value is exceeded, control element sends control signal to the electronic pump 3 of fork truck, reduces delivery quality, the speed of fork truck is reduced to limit value, such as 10Km/h, 15Km/h.
Whole fork truck speed-limiting control device need to have a parameter input device, this parameter input device is selected keyboard entry method, for parameter input module, can be touch-screen input mode, also can adopt traditional Keyboard Control panel input mode, at this, not limit.
The installation of speed sensor can be selected dual-host backup pattern, and at change speed gear box and propons while installation rate sensor, the in the situation that of the sensor failure of a certain position, another sensor starts back information, has reduced the risk of fork truck stall.
Can visualized operation for better giving operating personal, it is comparatively desirable that speed state display module is introduced to fork truck speed-limiting control device, velocity amplitude actv. can be shown to manipulator.This speed state display module can be LCD/LED read-out, can be also Speed display gauge panel.
When fork truck is controlled in intellectuality, in conjunction with telltale, giving personnel warns and is absolutely necessary, when control element acquisition speed surpasses limit value, adopting the buzzer phone/alarm lamp being connected with micro controller system to warn and can disposing for dangerous strick precaution is that an actv. supplements.
The existing control instrument of my company can directly be connected into this fork truck speed-limiting control device, without repacking separately again, only need the data line of speed sensor and controller (control element) to insert control instrument, this control instrument is installed on forklift steering room.
It should be noted that, this case is except controlling electronic pump, and control element also connects and the automatic brake system of fork truck, works as excessive velocities, when reducing oil supply, utilize control element to send that the automatic brake system of signal control fork truck is braked fork truck and reduction of speed to preset value.
The automatic brake system of fork truck power system and fork truck is existing known technology, at this, does not repeat.The speed of utilizing the corresponding electronic devices and components of control to control fork truck is to realize the intelligent precondition of controlling.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not depart from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
