Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1, the pneumatic lifting safety device for the electric furnace door comprises a body part, a pneumatic part and a control part, specifically, the safety device of the embodiment comprises a body base 7 and a cylinder base 9 which are fixedly arranged on a cradle frame of the electric furnace, and a protection body 10 which is hinged to the body base through a horizontal hinge shaft, wherein the protection body extends to a position between the electric furnace rotating frame and an operation platform, and the protection body is arranged to prevent personnel from falling from a high-suspension space gap existing between the electric furnace rotating frame and the operation platform.
The protection body of this embodiment includes along the closed rectangular frame body of circumference to and a plurality of montants of rigid coupling in the rectangular frame body, each montant distributes in proper order along the length direction of the rectangular frame body. One side of the horizontal hinge shaft far away from the driving cylinder is provided with a balancing weight 6 fixedly connected with the protection body, so that the load of the driving cylinder is reduced, and the effective length of the protection body can be freely adjusted by calculating the size of the balancing weight. The protective body is fixedly connected with two supporting legs supported on the top surface of the electric furnace cradle frame, so that when the protective body is put down, the lower ends of the supporting legs are supported on the top surface of the electric furnace cradle frame, the long-time load of the driving cylinder is avoided, and the service life of the cylinder is prolonged.
The air cylinder base is provided with a driving air cylinder for driving the protection body to rotate around the horizontal hinge shaft, and the driving air cylinder is communicated with an air source through an air supply pipeline. The driving cylinder of this embodiment is two buffer cylinder, has improved the stability of protector action, and when the cylinder stroke target in place, the speed of cylinder piston rod can slow stop, and the impact phenomenon that can effectively prevent to collide and bring takes place, reduces the vibration, improves whole action stationarity, improves the device life. Specifically, a two-position five-way electromagnetic directional valve 5 is installed on the air supply pipeline, a right exhaust port of the two-position five-way electromagnetic directional valve communicated with a rod cavity of the driving cylinder is communicated with a first exhaust throttle valve, and a left exhaust port of the two-position five-way electromagnetic directional valve communicated with a rodless cavity of the driving cylinder is communicated with a second exhaust throttle valve 4. The purpose of controlling the rising and falling action speed of the protective device is achieved by adjusting the flow of the exhaust throttle valve; the purpose of increasing or decreasing the lifting acting force of the protective device is achieved by adjusting the pressure of the pressure reducing valve; the purpose of remote safe operation is achieved through power failure of the electromagnetic directional valve; and the action of the protective device can be not interfered with other equipment and facilities around the furnace body by additionally arranging an electric automatic interlocking function.
The specific use process is that on the basis of the existing gas source 1, a compressed air pipeline is connected in a side-by-side mode, a ball valve 2 is additionally arranged for switching on and off gas circulation, after gas passes through a pneumatic triple piece 3, a piston rod of a driving cylinder 8 is controlled to stretch and retract through a two-position five-way electromagnetic directional valve 5, when the pneumatic triple piece works, the two-position five-way electromagnetic directional valve 5 is electrified, the directional valve is in the right position, a rodless cavity of the cylinder is ventilated, a rod cavity exhausts gas, the piston rod of the cylinder extends out, and a protection body 10 begins to be lifted up slowly; when the two-position five-way electromagnetic reversing valve is powered off, the reversing valve is in the left position (normal position), the rod cavity of the cylinder is ventilated, the rodless cavity exhausts, and the piston rod of the cylinder retracts to drive the protection body 10 to descend. Before the air cylinder is used for the first time, the opening degree of the two exhaust throttle valves is continuously adjusted according to the requirement of the rising and falling speed, and the action speed of the piston rod of the air cylinder is controlled until the proper rising and falling speed is obtained.
The protection body of this embodiment is circular elevating movement around the horizontal hinge on the body base, and if need artifical when the operation of furnace gate mouth, safety device falls, prevents that personnel from falling carelessly, and when other equipment need follow the operation of furnace gate mouth, protector lifts. Through the design and the use of a pneumatic system, the reasonable lifting speed is ensured, the use safety performance of equipment is improved, and the purposes of automation and remote control are conveniently achieved. The electric switch is additionally arranged in the main control chamber to control the two-position five-way electromagnetic directional valve to lose power, so that the bidirectional action of the cylinder is controlled, and the purpose of remote safe operation can be achieved because the electric switch is arranged in the main control chamber.
If there is the equipment that action, stroke and safety device conflict at the scene, can set up automatic interlocking as required, when safety device is in normal position, other equipment forbid at the furnace gate mouth action, when safety device is in the position of lifting, other equipment are at the furnace gate mouth operation this moment, then safety device forbids to fall.
Of course, the above description is not limited to the above examples, and technical features of the present invention that are not described in the present application may be implemented by or using the prior art, and are not described herein again; the above embodiments and drawings are only used for illustrating the technical solutions of the present invention and are not intended to limit the present invention, and the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the claims of the present invention.
