Abstract
The open a kind of lorry bridle coupler body following device of this utility model, including: coupler body, sensor, compression pump, pressure cylinder, PLC control unit；After described coupler body rises and touches sensor, signal is passed to PLC control unit by described sensor, the compression pump delay working time is controlled by described PLC control unit, and keep overbottom pressure in making described pressure cylinder, during goods load-carrying gradually decreases, the car body that in described pressure cylinder, overbottom pressure promotes piston driving coupler body to follow lorry gradually rises, and is used for so that described coupler body and car body remain safe locking state.This utility model passes through PLC control unit or time-delay relay so that coupler body and truck body can remain safe locking state, safe and reliable, it is to avoid the potential safety hazard broken off relations, simple and practical, it is not necessary to safeguard, cost-effective.
Description
Technical field
This utility model relates to a kind of lorry bridle coupler body following device.
Background technology
During lorry is unloaded, truck body alleviates due to goods weight, and chassis of vehicle body can rise automatically, and coupler body
The most fixed, thus cause coupler body can not hook lorry and cause breaking off relations, produce potential safety hazard, frequently result in peace
The generation of full accident.In prior art, be normally only machinery liquid (gas) cylinder pressure be additionally arranged at the bottom spring, but spring is easy
Cause mechanical fatigue, damage spring, reduce service life, increase cost of equipment maintenance, and increase potential safety hazard.And due to
Liquid (gas) cylinder pressure is in the effect of opposite force all the time, causes coupler body easily to produce fault during declining, and exacerbates liquid (gas)
The load of press pump motor, reduces the service life of equipment.
Utility model content
For above-mentioned technical problem, this utility model provides a kind of lorry bridle coupler body following device.
This utility model be the technical scheme is that
A kind of lorry bridle coupler body following device, including: coupler body, sensor, compression pump, pressure cylinder, PLC control single
Unit；After described coupler body rises and touches sensor, signal is passed to PLC control unit by described sensor, by described PLC
Control unit controls the compression pump delay working time, and makes holding overbottom pressure in described pressure cylinder, gradually decreases in goods load-carrying
Cheng Zhong, the car body that in described pressure cylinder, overbottom pressure promotes piston driving coupler body to follow lorry gradually rises, and is used for so that described coupler body
Safe locking state is remained with car body.
Described PLC control unit can also replace with time-delay relay.
The beneficial effects of the utility model are by PLC control unit or time-delay relay so that compression pump and pressure
Cylinder energy delay working a period of time, the car body continuing to drive coupler body to follow lorry gradually rises so that coupler body and truck body energy
Enough remain safe locking state, safe and reliable, it is to avoid the potential safety hazard broken off relations, simple and practical, it is not necessary to safeguard,
Cost-effective.
Accompanying drawing explanation
Fig. 1 is the principle schematic of lorry bridle coupler body following device described in the utility model；
In figure: 1, coupler body；2, sensor；3, compression pump；4, pressure cylinder；5, PLC control unit.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As it can be seen, the open a kind of lorry bridle coupler body following device of this utility model, including: coupler body 1, sensor 2,
Compression pump 3, pressure cylinder 4, PLC control unit 5；After described coupler body 1 rises and touches sensor 2, described sensor 2 is by signal
Pass to PLC control unit 5, control the compression pump 3 delay working time by described PLC control unit 5, and make described pressure cylinder
Keeping overbottom pressure in 4, during goods load-carrying gradually decreases, in described pressure cylinder 4, overbottom pressure promotes piston driving coupler body 1 to follow goods
The car body of car gradually rises, and is used for so that described coupler body 1 remains safe locking state with car body.Described PLC control unit 5
Time-delay relay can also be replaced with.This utility model passes through PLC control unit 5 or time-delay relay so that compression pump 3 He
Pressure cylinder 4 energy delay working a period of time, the car body continuing to drive coupler body 1 to follow lorry gradually rises so that coupler body 1 and lorry
Car body can remain safe locking state, safe and reliable, it is to avoid the potential safety hazard broken off relations, simple and practical, is not required to
Safeguard, cost-effective.
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment
Listed utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art,
It is easily achieved other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, this reality
It is not limited to specific details and shown here as the legend with description with novel.
Claims (2)
1. a lorry bridle coupler body following device, it is characterised in that including: coupler body, sensor, compression pump, pressure cylinder,
PLC control unit；After described coupler body rises and touches sensor, signal is passed to PLC control unit by described sensor, logical
Cross described PLC control unit and control the compression pump delay working time, and make to keep in described pressure cylinder overbottom pressure, goods load-carrying by
During decrescence few, the car body that in described pressure cylinder, overbottom pressure promotes piston driving coupler body to follow lorry gradually rises, be used for so that
Described coupler body and car body remain safe locking state.
Lorry bridle coupler body following device the most according to claim 1, it is characterised in that: described PLC control unit is also
Could alternatively be time-delay relay.
