Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 and 2, the present embodiment provides a solenoid valve operating device for a subway train emergency pantograph lifting device, which includes a bending member 1, a top sleeve 2, a nut 3, a screw rod 4 and a rotating handle 5.
The steel plate with the bending piece 1 formed integrally comprises a first side plate 11, a connecting plate 12 and a second side plate 13, wherein the first side plate 11 and the second side plate 13 are perpendicularly arranged at two ends of the connecting plate 12 to form a 'door' shape. The bending piece 1 is made of 45 # steel which has both toughness and strength. The width of the bending piece 1 is generally 23-28 mm, and in the embodiment, 25mm is adopted; the thickness of the bending piece 1 is generally 3-6 mm, and in the embodiment, 5mm is adopted; in this embodiment, the length of the connecting plate 12 is 144mm, and the lengths of the first side plate 11 and the second side plate 13 are the same, and are both 60mm, so that the shape of the connecting plate can basically fit all kinds of existing emergency pantograph lifting electromagnetic valves.
Be equipped with first through-hole on first curb plate 11, rotatory handle 5 is connected to the one end of screw rod 4, and the other end passes nut 3 and first through-hole in proper order and connects top cover 2 to nut 3 welds the outside at first curb plate 11. According to the structure, the screw thread is not directly arranged in the through hole of the bending piece 1 to connect the screw rod 4, the screwing stability is ensured, meanwhile, the thickness of the bending piece 1 can be made thinner, and the overall weight and the cost of the device are reduced.
The left end of the screw rod 4 is provided with a mounting hole, the rotating handle 5 is a connecting rod provided with anti-skidding threads, the middle part of the connecting rod penetrates through the mounting hole and is welded, and the axial direction of the connecting rod is perpendicular to the axial direction of the screw rod 4. Thereby, the screw 4 can be rotated along the thread of the nut 3 by rotating the connecting rod, so that the top sleeve 2 is moved axially along the screw 4.
The top sleeve 2 is a rubber top sleeve 2, is fixed at one end of a screw rod 4, is generally cylindrical, and is provided with anti-skid lines on one side contacting with the button. The top sleeve 2 can also be in a semi-spherical shape or a spherical shape, and the elastic spherical surface contact button deforms, so that the pressing effect is better and firmer.
The working principle of the embodiment is as follows:
as shown in figure 3, the emergency pantograph-ascending electromagnetic valve 6 in the cabinet 7 has the button 61 of the pantograph-ascending switch positioned at one side end, when in use, the auxiliary device is placed on the outer ring of the electromagnetic valve, specifically, the connecting plate 12 is positioned on the front surface of the electromagnetic valve, then the rotating handle 5 is screwed to rotate the screw rod 4, the screw rod 4 drives the ejection sleeve 2 to advance leftwards to eject the button 61 of the battery valve, and after the ejection sleeve 2 completely ejects the button 61, a clamping force is formed between the ejection sleeve 2 and the second side plate 13, so that the device is firmly clamped on the emergency pantograph-ascending electromagnetic valve 6 and is in a state of long-pressing of the button 61. At the moment, the air passage of the electromagnetic valve is opened, and the compressed air supplies air to the pantograph lifting device through the pipeline, so that the lifting action of the pantograph is completed. Use this device to solve subway train and risen the problem that the bow solenoid valve needs the staff to press by pure manual, liberated staff's both hands, reduce fatigue degree, can avoid moreover because the problem that the artificial hand-loosening caused the potential safety hazard.
