Description
Technical field
The utility model relates to the conveying correlative technology field that is welded, and especially relates to a kind of contact safety pedal.
Background technology
In Riciprocating bar type conveyor automotive welding production line, people and equipment need collaborative work, have on the plant equipment of potential danger at this, if the operating personnel is in the situation that without any personnel's safety precautions, very easily cause personal injury.Due to the restriction of investment and production capacity, what major part still adopted at present is the manual welding operating type, manually picks and places workpiece, Riciprocating bar type conveyor transportation body shell.Due to not concrete effectively safeguard procedures on welding line, between two chassis bodies or on conveyor, if the operating personnel is careless and inadvertent, the other staff (as checker, technologist) that perhaps are unfamiliar with this post enter the operation area, just exist and be transferred the danger that machine is brought pipeline into, potential safety hazard is larger.Along with improving constantly that vehicle body production efficiency is required, productive temp is accelerated, and transporting velocity significantly improves, when fully satisfying production capacity and quality, it is more outstanding that the requirement of security protection also seems, is necessary very much on the pipeline that is welded planning and disposes the associated safety system.
Chinese patent application notification number: CN 102416428A, the application day for announcing is on April 18th, 2012, a kind of Novel punch protection device is disclosed, device body comprises fuselage and Machine-Tool Control case, device body also comprises brake gear, air compression plant, travel switch, solenoid valve, the quantity of solenoid valve is two, brake gear comprises clutch coupling, the clutch coupling fixed mount, clutch shaft, clutch disc, spring, clutch plate, braked wheel, brake ribbon, brake spring, the punch press bull wheel, punch crank, air compression plant comprises two upper cylinders, two pistons and two clutch disc, brake gear is connected with solenoid valve, air compression plant is connected with another described solenoid valve.By the emission infrared ray, produce protection light curtain, when the light curtain was blocked, device sent shielding signals; the plant equipment that control has potential danger quits work, and avoids occuring security incident, and the weak point of this invention is; cost is higher, and independent space is set, and the later stage, relative maintenance cost was high.
The utility model content
The utility model is to need to arrange independent space in prior art and the higher problem of cost and maintenance cost in order to overcome, and providing a kind of does not need to arrange independent space and the lower contact safety pedal of cost and maintenance cost.
To achieve these goals, the utility model is by the following technical solutions:
A kind of contact safety pedal of the present utility model, comprise: pedal, contactor control device and PLC controller, described contactor control device comprises support, spring, base and travel switch, described is placed under pedal, described spring fitting is on support, described base sheath is followed spring, and described contactor control device is connected with the PLC controller by travel switch.
Described is placed under pedal, described spring fitting is on support, described base sheath is followed spring, forms like this a contactor control device, when pushing down on the pedal, be accompanied by the effect of spring, support moves simultaneously, and described contactor control device is connected with the PLC controller by travel switch, and contactor control device triggers the travel switch action, make the PLC controller control the pipeline that is welded by travel switch and quit work, thus the security that improves production line.Design does not need to arrange independent space like this, only need to be arranged on the below of pedal, and cost is low and relative maintenance cost of later stage is also lower.
As preferably, described support is provided with guide rod, and described spring fitting is on the guide rod of support, and guide rod and base are used in conjunction with, and play the location booster action, and the relative displacement that can prevent support causes the wearing and tearing of device.
As preferably, described PLC controller is provided with status indicator lamp, described status indicator lamp connects travel switch, by this indicating lamp display mode, can judge accurately and effectively the horse block switch existing problems of that station, make the people very clear after adding status indicator lamp, failure judgement is in time processed problem fast.
As preferably, described support is rectangular steel tube, and is simple in structure, saves cost.
As preferably, described pedal is provided with Safety floor pad, and Safety floor pad is lower to the requirement in space, and lays simple, dependable performance, has good adaptability for mobile device and small size protection.
The beneficial effects of the utility model are: do not need to arrange independent space, only need to be arranged on the below of pedal, failure judgement is in time processed problem fast, and the later stage, relative maintenance cost was also lower, had improved the security of production line, and is simple in structure, saves cost.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1. pedal, 2. support, 3. guide rod, 4. spring, 5. base.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1, a kind of contact safety pedal, comprise pedal 1, contactor control device and PLC controller, contactor control device comprises support 2, spring 4, base 5 and travel switch, support 2 is placed in pedal 1 time, spring 4 is arranged on support 2, and base 5 covers are spring 4 then, and contactor control device is connected with the PLC controller by travel switch.The PLC controller is provided with status indicator lamp, and status indicator lamp connects travel switch.The PLC controller includes PLC repeater box and PLC master control cabinet, travel switch connects the PLC repeater box, the PLC repeater box connects PLC master control cabinet, PLC master control cabinet connects carries motor, the input signal that produces by travel switch is to the PLC repeater box, then carries out signal and communication by the PLC repeater box by the PROFIBUS bus, and the input signal of collection is transferred to PLC master control cabinet by communication bus, control the running status of the pipeline that is welded by the travel switch of PLC master control cabinet collection, the security that has improved production line.Support 2 is provided with guide rod 3, and spring 4 is arranged on the guide rod 3 of support 2, and guide rod 3 is nested in base 5 and is used in conjunction with, and is used for retainer spring 4.Support 2 is rectangular steel tube, and pedal 1 is steel plate.Pedal 1 is provided with Safety floor pad, and its requirement to the space is lower, and lays simple, dependable performance, has good adaptability for mobile device and small size protection.Pedal 1 is arranged between two stations of the pipeline that is welded, namely be arranged on the local location that reaches personnel operation on conveyor, when conveyor in lifting, advance, descend, retreat this actuation cycle in the cycle, in case operating personnel's pin drops on pedal, production line will stop action in 20ms, thus the security that greatly improves production line.
