Abstract
The utility model relates to an operator invasion safety protection device of a final assembly line elevator, which includes a first vehicle body detection switch, a second vehicle body detection switch and an operator invasion detection switch, wherein the first vehicle body detection switch and the second vehicle body detection switch are installed on the inner side of a guardrail notch of the elevator respectively, and the operator invasion detection switch is installed at an entrance of the guardrail notch of the elevator; and the first vehicle body detection switch, the second vehicle body detection switch and the operator invasion detection switch are connected with an PLC (programmable logic controller) input terminal respectively. The operation invasion safety protection device has the advantages that the influence on normal moving out of the vehicle body is avoided, the safety of an invader is ensured to a largest extent, the scheme is simple and the cost is low.
Description
Technical field
The utility model relates to a kind of safety protection device, specifically is that the worker of the final assembly line lift of automobile invades safety protection device.
Background technique
In the flow production line of automobile, final assembly line is a last ring.Final assembly line mainly is made up of vehicle body lift and plate chain.Assembly line gets into final assembly line lift through friction wheel from the chassis to load the suspender of vehicle body, on the plate chain that lift falls earthward vehicle body, on the plate chain, accomplishes the final assembling of automobile.Around lift, guardrail has been installed generally and has been prevented that the people from getting into the lift zone, but guardrail must stay a breach so that vehicle body is taken out of on plate chain rotation direction, so the people also can arbitrarily get into the lift zone through this breach, personal safety is constituted a threat to.Because vehicle body also passes through from crossing this breach, the object that does not also have a kind of sensor to distinguish in the market to pass through from here is people or car on earth, and the safety protection here is a difficult problem.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology, provides a kind of worker of final assembly line lift to invade safety protection device, for above-mentioned occasion provides a kind of scheme of safety protection, protects effractor's safety to the full extent.
According to the technological scheme that the utility model provides, the worker of said final assembly line lift invades safety protection device and comprises: the first vehicle body detecting switch, the second vehicle body detecting switch and worker invade detecting switch; It is inboard that the said first vehicle body detecting switch and the second vehicle body detecting switch are installed in lift guardrail breach, and said worker invades detecting switch and is installed in lift guardrail breach ingress; The first vehicle body detecting switch, the second vehicle body detecting switch are invaded the input end that detecting switch is connected PLC respectively with the worker.The transmitting terminal of each correlation optoelectronic switch and receiving terminal are installed in the both sides of assembly line plate chain respectively.
The said first vehicle body detecting switch, the second vehicle body detecting switch and worker invade detecting switch and all adopt the correlation optoelectronic switch.
Inwardly be followed successively by said worker from lift guardrail breach inlet and invade detecting switch, the second vehicle body detecting switch, the first vehicle body detecting switch; The second vehicle body detecting switch and worker invade the detecting switch distance and are generally 20 ± 5 centimetres, and the first vehicle body detecting switch and second vehicle body detecting switch distance are generally 0.5 ± 0.1 meter.
The utility model has the advantages that: can effectively detect the worker and invade behavior, scheme is simple, and is with low cost; Normally taking out of of car body do not influenced, and can protect effractor's safety to the full extent.
Description of drawings
Fig. 1 is the switch arrangement schematic representation of the utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1: it is inboard that the first vehicle body detecting switch 1 and the second vehicle body detecting switch 2 are installed in the guardrail breach, and the worker invades detecting switch 3 and is installed in guardrail breach ingress.The first vehicle body detecting switch 1 is contained in the most inboard; The first vehicle body detecting switch 1 and the second vehicle body detecting switch, 2 distances about about half meter (as 0.5 ± 0.1 meter); The second vehicle body detecting switch 2 is invaded detecting switch 3 distances about about 20 centimetres (as 20 ± 5 centimetres) with the worker; Three switches all adopt the correlation optoelectronic switch, and three switch height detect vehicle body with maximum possible and are as the criterion.The correlation optoelectronic switch is made up of transmitting terminal and receiving terminal, and the transmitting terminal of each correlation optoelectronic switch and receiving terminal are installed in the both sides of plate chain respectively.Three correlation optoelectronic switches insert the input end of PLC respectively.
Vehicle body is taken out of in the process by the plate chain after falling the plate chain, and the first vehicle body detecting switch 1 will detect vehicle body at first, is that the second vehicle body detecting switch 2 detects vehicle body then, is that the worker invades detecting switch 3 and detects at last.When the first vehicle body detecting switch 1 and the second vehicle body detecting switch 2 detect object simultaneously; Can judge that vehicle body will take out of; The worker invaded detecting switch 3 and lost efficacy this moment, promptly the worker invade detecting switch 3 when detecting object PLC can not report to the police, equipment runs well; After vehicle body is taken out of from the lift zone; When the first vehicle body detecting switch 1, the second vehicle body detecting switch 2, worker invade detecting switch 3 when detecting less than object; The worker invades detecting switch 3 and recovers effectively; This moment the worker invade detecting switch 3 when detecting object PLC will drive warning device and report to the police, and the order lift stops to turn round.
In sum; From the first vehicle body detecting switch 1 and the second vehicle body detecting switch 2 detect simultaneously object to the first vehicle body detecting switch 1, the second vehicle body detecting switch 2, worker invade detecting switch 3 all detect less than object during this period of time in; The worker invades detecting switch 3 and lost efficacy; If someone during this period of time gets into the lift zone, PLC will can not report to the police, and not have protective action; Except that during this period of time, it is all effective that the worker invades detecting switch 3, and the someone gets into lift zone PLC and can report to the police, and has protected effractor's safety to the full extent.
