Abstract
A kind of limit control system of overhead and gantry cranes, relate to a kind of control system, it includes being positioned at the stopping means being arranged on grab bucket or shackle hook, also include that the spacing wireless signal transmitting device being arranged on grab bucket or shackle hook and the limit signal being arranged in switch board receive device, after the limit signal of stopping means output is sent by wireless signal transmitting device, being received device by limit signal to receive, limit signal receives device serial connection and controls in loop in grab bucket or shackle hook.This utility model provides the limit control system of a kind of overhead and gantry cranes, overcome motor grab bucket and electric rotary lifting hook limit signal is inconvenient to the shortcoming that is transferred in switch board, limit signal can be serially connected in the most easily in control loop in the case of need not controlling cable.
Description
Technical field
This utility model relates generally to a kind of control system, especially relates to the spacing control system of a kind of overhead and gantry cranes
System.
Background technology
At present, spacing on the grab bucket of motor on overhead and gantry cranes, electric rotary lifting hook is that mechanical type is spacing, signal one
As be all the cable on the cable drum on trolley body, dolly towing cable and crane span structure line in switch board.Need often to exist
Unwrapping wire repeatedly it is wound around, it is also desirable to often move with dolly, be the most easily pulled off on cable drum.And want on cable drum
Together with being fixed on main power line in a strand, being relatively large in diameter of such cable, in the case of lifting altitude is higher, increase
Add the difficulty being wound around.
Utility model content
This utility model is for the shortcoming solving above-mentioned prior art, it is provided that the spacing control of a kind of overhead and gantry cranes
System, it is possible in the case of without cable, limit signal is transferred in switch board.
This utility model is achieved in that the limit control system of a kind of overhead and gantry cranes, is arranged on including being positioned at
Stopping means in grab bucket or shackle hook, also includes the spacing wireless signal transmission being arranged on grab bucket or shackle hook
Device and the limit signal being arranged in switch board receive device, and the limit signal of stopping means output is sent out by wireless signal
After injection device sends, limit signal receiving device and receive, limit signal receives device serial connection in grab bucket or shackle hook control
In loop processed.
Described spacing receiving device connects auxiliary reclay, and the normally opened contact of this auxiliary reclay is connected on grab bucket or rotation
Turn suspension hook to control in loop.
Described spacing wireless signal transmitting device is powered by direct current 12v power supply, and this direct current 12v power supply is button power supply.
Relative to prior art, the beneficial effects of the utility model are: provide the spacing control of a kind of overhead and gantry cranes
System processed, overcomes motor grab bucket and electric rotary lifting hook limit signal is inconvenient to the shortcoming that is transferred in switch board, Ke Yi
In the case of need not controlling cable, limit signal is serially connected in the most easily in control loop.
Accompanying drawing explanation
Fig. 1 is control principle drawing of the present utility model.
Wherein, 1, stopping means, 2, auxiliary reclay, 3, grab bucket close push button, 4, auxiliary reclay normally opened contact, 5, grab
Bucket Guan Bi catalyst, 6, spacing wireless signal transmitting device, 7, limit signal receive device.
Detailed description of the invention
As it is shown in figure 1, the limit control system of a kind of overhead and gantry cranes, it is arranged on grab bucket or rotating lifting including being positioned at
Stopping means 1 on hook, also includes being arranged on the spacing wireless signal transmitting device 6 on grab bucket or shackle hook and installing
Limit signal in switch board receives device 7, and the limit signal of stopping means output is sent by wireless signal transmitting device 6
After, limit signal receiving device 7 and receive, limit signal receives device serial connection and controls in loop in grab bucket or shackle hook.
Described spacing receiving device 7 connects auxiliary reclay 2, and the normally opened contact 4 of this auxiliary reclay is connected on grab bucket
Or shackle hook controls in loop.
Described spacing wireless signal transmitting device 6 is powered by direct current 12v power supply, and this direct current 12v power supply is button power supply.
In use, grab bucket normal opening and closing time, stopping means 1 is in normally off, and spacing wireless signal transmission fills
Putting 6 and send signal, after limit signal reception device receives signal, make auxiliary reclay 2 coil adhesive, auxiliary reclay is normally opened to be touched
Point 4 Guan Bi, can make grab bucket normally closed when close push button 3 of grabbing bucket closes；When grab bucket Guan Bi is complete, stopping means is normally closed to be touched
Point 4 disconnection, spacing wireless signal transmitting device 6 sends signal, after limit signal reception device 7 receives signal, makes middle relay
Device 2 coil disconnects, and auxiliary reclay normally opened contact 4 disconnects, and makes grab bucket close catalyst 5 power-off, thus protects motor grab bucket each
Associated components.
This using method is to illustrate as a example by grab bucket, and shackle hook is in like manner.
Embodiment described above, the simply one of this utility model more preferably detailed description of the invention, the skill of this area
The usual variations and alternatives that art personnel are carried out in the range of technical solutions of the utility model are intended to be included in guarantor of the present utility model
In the range of protecting.
