Description

Technical Field

[0001] The utility model belongs to the technical field of switch machines, and in particular relates to a waterproof and dustproof switch machine. Background Art

[0002] As the actuator of the turnout control system, the switch machine can reliably convert the turnout position, change the turnout opening direction, and lock the turnout point rail, thereby ensuring driving safety, improving transportation efficiency, and reducing the labor intensity of drivers.

[0003] Since the switch machine is installed next to the outdoor railway tracks, the operating rod of the switch machine is exposed to the external environment. When it rains, rainwater and splashed dust will adhere to the operating rod. When the switch machine is in operation, rainwater and dust will be brought into the machine through the movement of the operating rod, thereby affecting the electrical performance of the switch machine.

[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, a waterproof and dustproof transfer machine includes a machine body 1 fixedly mounted on a railroad sleeper via a connecting member. The connecting member includes a fixing plate 3 fixedly connected to the lower surface of the machine body 1. Fixing holes 4 are formed at both ends of the fixing plate 3 to facilitate users to pass external bolts through the fixing holes 4 and then screw the fixing plate 3 to the railroad sleeper.

[0021] Multiple heat dissipation fins 2 are fixedly welded to the front and rear sides of the top of the body 1. The multiple heat dissipation fins 2 are evenly distributed along the length of the body 1, and a gap is left between two adjacent heat dissipation fins 2. The heat dissipation fins 2 are used to increase the contact surface between the top side of the body 1 and the external environment, which is conducive to the rapid dissipation of heat generated by the body 1 during operation through the heat dissipation fins 2;

[0022] An oil cylinder 5 is fixedly installed on one side of the machine body 1, and a piston rod 6 installed on the output end of the oil cylinder 5 is passed through the other side of the machine body 1. A joint 7 is fixedly installed on the end of the telescopic section of the piston rod 6 away from the oil cylinder 5. The joint 7 has a U-shaped structure, and through holes for fixing the switch rail are opened on the side walls on both sides of the joint 7. When the machine body 1 controls the oil cylinder 5 to start, the oil cylinder 5 can push the piston rod 6 to extend and retract, driving the switch rail to move, thereby adjusting the position of the switch rail. Indicator rods 8 are installed on the machine body 1 on both sides of the piston rod 6. The two indicator rods 8 are symmetrically arranged to detect and monitor the close contact state of the switch rail;

[0023] The outer surface of the piston rod 6 is provided with a bellows sleeve 9, one end of the bellows sleeve 9 is fixedly connected to an elastic rubber ring 10, the elastic rubber ring 10 is sleeved on the fixed section of the piston rod 6 and is clamped with the fixed section of the piston rod 6, the other end of the bellows sleeve 9 is fixedly connected to a clamping tube 11, the clamping tube 11 is a truncated cone structure, the clamping tube 11 is sleeved on the end of the telescopic section of the piston rod 6 away from the oil cylinder 5, the clamping tube 11 is symmetrically provided with four shrinkage holes 12 on the side wall of the end away from the bellows sleeve 9, the outer surface of the clamping tube 11 is provided with an external thread 13, the clamping tube 11 is also sleeved with an inner screw ring 14, the inner screw ring 14 is screwed to the clamping tube 11 through the external thread 13, the inner wall of the clamping tube 11 close to the bellows sleeve 9 is fixedly connected with a sealing ring 15, the sealing ring 15 is sleeved on the telescopic section of the piston rod 6 and fits tightly against the outer wall of the telescopic section of the piston rod 6.

[0024] It should be noted that when using this waterproof and dustproof switch and withdrawal machine, first, the bellows sleeve 9 is sleeved on the piston rod 6 from one end of the piston rod 6 connecting joint 7, and then the end of the bellows sleeve 9 connected to the elastic rubber ring 10 is sleeved and fixed on the fixed section of the piston rod 6, and then the bellows sleeve 9 is stretched until the clamping tube 11 slides to the end of the telescopic section of the piston rod 6 away from the oil cylinder 5. At this time, the inner screw ring 14 can be screwed toward the end with the larger diameter of the clamping tube 11, and the clamping tube 11 is squeezed along the contraction hole 12 by the inner screw ring 14 until the end with the smaller diameter of the clamping tube 11 is tightly fitted with the outer wall of the telescopic section of the piston rod 6, so that the bellows sleeve 9 can be fixed. The telescopic section of the piston rod 6 is covered and protected by the bellows sleeve 9 to prevent rainwater and dust from adhering to the telescopic section of the piston rod 6 as much as possible, which is easy to be brought into the machine body 1 during the contraction process of the piston rod 6, thereby affecting the electrical performance of the switch machine.

[0025] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
