Abstract

The utility model discloses a high lifting portal speed limiting system. A forklift portal is provided with a plurality of position sensors in the vertical direction, a forklift frame is provided with induction sheets which are matched with the position sensors to obtain altitude signals of the forklift frame, the position sensors output the altitude signals of the forklift frame to a drive controller of a forklift, and the drive controller outputs a speed limiting signal to a forklift walking motor. According to the high lifting portal speed limiting system, when the forklift lifts goods, the dangerous situations that when the goods walk at the high position and the forklift speed is excessively high, the forklift can roll over and turn over front and back, and the goods can be thrown away are avoided. Misoperation is prevented, labor intensity is reduced, and walking safety and walking efficiency are improved. An existing controller does not need to be greatly changed, in addition, few resources of the controller are consumed by the system, and electric energy is saved.

Description

A kind of high door frame speed limiting system that hoists

Technical field

The utility model belongs to the technical field of industrial vehicle, and specifically, type relates to a kind of electri forklift control technology.

Background technology

During industrial vehicle operation at present, often need the high goods walking that hoists, there will be following problem at this point: as reach truck in the goods lifting, goods is in high-order walking, if the speed of a motor vehicle is too fast will cause rollover, turn over front and back, the dangerous situation such as throw away with goods, at present, avoid accident that full subjective consciousness and driving experience by chaufeur occurs, have potential safety hazard.If the potential safety hazard of avoiding and limit the car load moving velocity, can cause again production efficiency significantly to reduce.

The utility model content

Technical problem to be solved in the utility model is to realize a kind of height that can guarantee fork truck safety traffic door frame speed limiting system that hoists.

To achieve these goals, the technical solution adopted in the utility model is: a kind of high door frame speed limiting system that hoists, the forklift door frame vertical direction is equipped with a plurality of position transdusers, on goods shelf, be equipped with and with position transduser, coordinate the sensing chip that obtains its altitude signal, described position transduser output goods shelf altitude signal is to the travel controller of fork truck, and described travel controller output restricting signal is to the forklift-walking motor.

Described position transduser is provided with three, lays respectively at three positions of upper, middle and lower of door frame, and door frame is divided into to a not speed limit height of speed limit height and two grades.

The utility model has the advantage of, this system can, when the forklift lifting goods, avoid goods to be in high-order walking, the speed of a motor vehicle is too fast will cause rollover, turn over front and back the dangerous situation such as throws away with goods, prevent maloperation, reduce labour intensity, improve walking safety and efficiency.And need on existing controller, not do large change, this system consumption controller resource is few in addition, save electric energy.

The accompanying drawing explanation

Below the content of every width accompanying drawing expression in the utility model specification sheets and the mark in figure are briefly described:

Fig. 1 is the height door frame speed limiting system structural representation that hoists;

Mark in above-mentioned figure is: 1, position transduser; 2, sensing chip; 3, travel controller; 4, movable motor.

The specific embodiment

As can be known referring to Fig. 1, the high door frame speed limiting system that hoists of the utility model is installation site sensor 1 and sensing chip 2 on existing fork truck, to control fork truck under the different operating state, gives different standard of the limited speed, and transformation is convenient, and result of use is good.

Specifically, position transduser 1 arranges a plurality of, along the forklift door frame vertical direction, install, sensing chip 2 matches with position transduser 1, be installed on goods shelf, like this in the goods shelf motion process, 2 of position transduser 1 and sensing chips can coordinate the Position Approximate state of measuring goods shelf, for saving improvement cost, position transduser 1 can be provided with three, lay respectively at three positions of upper, middle and lower of door frame, door frame is divided into to a not speed limit height of speed limit height (bottom) and two grades (middle and top).After position transduser 1 acquisition goods shelf altitude signal, be delivered to the travel controller 3 of fork truck, this travel controller 3 can be according to default corresponding standard of the limited speed output restricting signal to forklift-walking motor 4, thereby control goods shelf and at differing heights, give the speed limit (or not speed limit) of different brackets, when the forklift lifting goods is in a high position, maximum travel speed increases and step-down with the goods lift height, the restriction moving velocity, in the safe velocity scope, reaches goal of the invention.

The above is exemplarily described the present invention by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out as long as adopted; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
