By the adoption of the device for controlling the pressure of circulating cooling water for the mechanical arm, the situation that a clamp deforms and breaks down due to water shortage of the mechanical arm can be prevented, and production efficiency is improved.
Description
Technical field
The utility model belongs to hot rolled seamless steel tube unit apparatus technical field, relates in particular to a kind of manipulator circulating cooling hydraulic control device.
Background technology
At present, in the existing hot rolled seamless steel tube unit of our factory, pipe blank enters heating furnace heating all needs manipulator to carry out work, after blank heating, temperature is up to 1300 degree, manipulator need at high temperature carry out work, recirculated cooling water can guarantee that the manipulator clamp of at high temperature working is indeformable, so the cooling water particular importance that just seems; Due to water-in and water-out valve damage or people be close forget to open, cooling water pump do not have pressure not show the appearance of the problems such as water, can cause manipulator at high temperature to be worked making that clamp is sagging, distortion and damaging, and equipment fault occurs, and affect hot rolling production.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of situation generation that can prevent that manipulator from causing clamp distortion, damaging because of lack of water is provided, the manipulator circulating cooling hydraulic control device of enhancing productivity, and its technical scheme is as follows:
A kind of manipulator circulating cooling hydraulic control device, comprise water tank and robot device, it is characterized in that, described water tank is connected with water inlet pipe and return pipe, the other end of water inlet pipe communicates with robot device, the other end of return pipe communicates with robot device, and water tank, return pipe, robot device, water inlet pipe form circulating backwater pipeline; On described water inlet pipe, be connected with clean circulating water pump, the pressure switch that can gather cooling water pressure signal is installed on described return pipe, pressure switch is connected with Programmable Logic Controller, Programmable Logic Controller is connected with robot device and alarm lamp, and Programmable Logic Controller can be controlled robot device and alarm lamp after can comparing by the cooling water pressure signal of collection and the cooling water pressure value of setting.
Optimal way is that described pressure switch is connected with Programmable Logic Controller by two core shielded cables.
The manipulator circulating cooling hydraulic control device that the utility model provides is installed a pressure switch on return pipe, the output signal of pressure switch is sent to on-the-spot Programmable Logic Controller and (is called for short: PLC); By write protection and alert program in Programmable Logic Controller, PLC carries out real-time monitoring to the signal of the pressure switch of collection in worksite, when cooling water pressure being detected when undesired, output alarm signal immediately, start alarm lamp, remind Field Force's manipulator to occur extremely needing shutdown inspection, stop manipulator simultaneously and work to high temperature place; After need waiting until that recirculated cooling water is normal, manipulator could normally be worked again.In process of production, as long as circulating cooling water pressure is undesired, manipulator just exits and quits work, after the cooling waters such as need are normal, can work on, avoid manipulator because of the situation generation that lack of water causes clamp distortion, damages, reduce equipment fault, enhance productivity.Further, by two core shielded cables, the output signal of pressure switch is received on Programmable Logic Controller, be convenient to the signal that Programmable Logic Controller gathers pressure switch, thereby realize by the pressure on circulating backwater pipeline, control mechanical hand starting and stop, situation generation that avoiding manipulator to cause clamp distortion, damage because of lack of water.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
As shown in Figure 1, a kind of manipulator circulating cooling hydraulic control device, comprise water tank 1 and robot device 2, described water tank 1 is connected with water inlet pipe 3 and return pipe 4, the other end of water inlet pipe 3 communicates with robot device 2, the other end of return pipe 4 communicates with robot device 2, and water tank 1, return pipe 4, robot device 2, water inlet pipe 3 form circulating backwater pipeline; On described water inlet pipe 3, be connected with clean circulating water pump 5, the pressure switch 6 that can gather cooling water pressure signal is installed on described return pipe 4, pressure switch 6 is connected with Programmable Logic Controller 7, and Programmable Logic Controller 7 is Siemens S7-300 controller.During setting pressure switch 6, the tapping of punching on return pipe 4, loads onto pressure switch 6, regulates the setting value (note: when pressure switch is transferred to pressure and is less than normal hydraulic pressure, output signal to Siemens S7-300 controller at once) of pressure switch.Programmable Logic Controller 7 is connected with robot device 2 and alarm lamp 8, and Programmable Logic Controller 7 can be controlled robot device 2 and alarm lamp 8 after can comparing by the cooling water pressure signal of collection and the cooling water pressure value of setting.Described pressure switch 6 is connected with Programmable Logic Controller 7 by two core shielded cables 9.
When using, pressure switch collects after cooling water pressure, cooling water pressure force signal is received the output signal of pressure switch on Siemens S7-300 controller by two core shielded cables, be convenient to the signal that controller gathers pressure switch, S7-300 controller carries out after information comparison, thereby realize by the pressure on water return pipeline, control mechanical hand starting and stop, situation generation that avoiding manipulator to cause clamp distortion, damage because of lack of water.
