Description

Technical Field

[0001] The utility model relates to the technical field of railway switch machines, in particular to an auxiliary tool for replacing the moving contact of a ZYJ7 type switch machine. Background Technique

[0002] The ZYJ7 switch equipment is a common switch mechanical equipment in the railway transportation system, which is widely used in the switching and turning of railway lines. It realizes the line change and turning of trains by changing the position of the track. The moving contact of the ZYJ7 type switch is an elastic self - reset mechanism. There are static contact grooves on both sides of the moving contact. Under the action of spring elasticity, the moving contact will tilt and closely adhere to one side of the static contact groove. When replacing the moving contact, it is necessary to overcome the spring elasticity to keep the moving contact always at the middle horizontal position between the two static contact grooves, and remove the fixing bolt between the moving contact and the contact seat, so as to complete the replacement of the moving contact.

[0003] At present, there is no professional tool for replacing the moving contact. When replacing the moving contact, a cooperating person is required to use a wrench to fix the moving contact adjusting bolt (linked with the moving contact), overcome the spring elasticity and pull it back, so that the moving contact adjusting bolt drives the moving contact to always remain at the middle horizontal position between the two static contact grooves. At the same time, another person needs to use a cross - screwdriver to remove the fixing bolt between the moving contact and the contact seat, remove the old moving contact, replace it with a new moving contact, and re - tighten the fixing screw between the moving contact and the contact seat to complete the replacement of the moving contact. During the operation process, the cooperating person needs to maintain a posture and continuously exert force to fix the moving contact adjusting bolt to prevent it from resetting. Prolonged exertion causes muscle fatigue, resulting in poor operation stability and accuracy. The replacement work requires a large amount of manpower input, low efficiency, high construction utilization rate and high labor cost. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides an auxiliary tool for replacing the moving contact of a ZYJ7 type switch machine, which can avoid fatigue operation of operators, reduce manpower input and improve operation efficiency.

[0022] Embodiment

[0023] As Figure 1 shown, the present utility model provides an auxiliary tool for replacing the moving contact of a ZYJ7 type switch machine, including:

[0024] A cross frame 1, made of stainless steel, with high strength, excellent rust and corrosion resistance, and a long service life;

[0025] A moving contact adjusting bolt fixer 2, which is arranged in the middle of the cross frame 1 and is used to fix the moving contact adjusting bolt of the ZYJ7 type switch machine, so that the moving contact is in the middle position between the two static contact grooves;

[0026] Limiters 3, one of which is provided at each end of the cross frame 1. The limiters 3 are used to fix the cross frame 1 on the housing of the ZYJ7 type switch machine. For example, bending parts are provided at both ends of the cross frame 1, and bolts are provided on the bending parts. When in use, open the cover of the ZYJ7 type switch machine, place both ends of the cross frame 1 on both sides of the housing respectively, and turn the bolts to fix the cross frame 1 on the housing of the ZYJ7 type switch machine.

[0027] The usage method of this device is as follows:

[0028] During use, open the cover of the ZYJ7 switch machine, and fix the cross frame 1 on the housing of the ZYJ7 switch machine through the limit member 3; with the left hand, pull the moving contact of the ZYJ7 switch machine to make the moving contact leave the static contact groove, drive the moving contact adjusting bolt to move to the moving contact adjusting bolt fixer 2, finely adjust the position of the cross frame 1, and fix the position of the moving contact adjusting bolt with the moving contact adjusting bolt fixer 2. In this way, the moving contact of the ZYJ7 switch machine is separated from the static contact groove and its position is fixed. Subsequently, the moving contact replacement operation is carried out.

[0029] In summary, for the moving contact replacement auxiliary tool of the ZYJ7 switch machine provided by the present utility model, the moving contact adjusting bolt fixer 2 is arranged in the middle of the cross frame 1, and the limit members 3 are arranged at both ends. The cross frame 1 is fixed on the housing of the ZYJ7 switch machine, and the moving contact adjusting bolt fixer 2 fixes the position of the moving contact. One worker can separate the moving contact of the ZYJ7 switch machine from the static contact groove, use the replacement auxiliary tool of the present utility model to fix the moving contact and then carry out the moving contact replacement operation. The operation is simple, avoiding the fatigue operation of the operator, reducing the labor input, and improving the operation efficiency.

[0030] In another technical solution, the moving contact adjusting bolt fixer 2 is a sleeve structure with a lower opening. During use, use the hand to pull the moving contact away from the static contact groove to make it in the middle position between the two static contact grooves on both sides, drive the moving contact adjusting bolt to move to the required fixed position, then align the sleeve structure with the moving contact adjusting bolt, and press down the cross frame 1 to sleeved the sleeve structure on the moving contact adjusting bolt.

[0031] In the ZYJ7 switch machine, the moving contact adjusting bolt is configured with a hexagonal nut. In another technical solution, the moving contact adjusting bolt fixer 2 is an internal hexagonal sleeve structure, and the moving contact adjusting bolt fixer 2 is rotatably connected to the cross frame 1. When the sleeve structure of the moving contact adjusting bolt fixer 2 and the moving contact adjusting bolt are sleeved, first manually rotate the sleeve structure to align the internal hexagon of the sleeve structure with the hexagonal nut configured on the moving contact adjusting bolt. In this way, when manually unloading the fixing bolt of the moving contact and the contact seat, the moving contact will not shake, which is convenient for unloading.

[0032] As Figure 2 、 Figure 3 shown, in another technical solution, a handle 21 is arranged on the upper part of the moving contact adjusting bolt fixer 2, and the lower part is an internal hexagonal sleeve structure. The handle 21 is fixedly connected to the upper end of the sleeve structure and penetrates through the cross frame 1. The handle 21 is rotationally and slidably connected to the cross frame 1. When the moving contact is pulled to align the moving contact adjusting bolt with the sleeve structure, press down the handle 21 to sleeve the sleeve structure on the moving contact adjusting bolt.

[0033] In another technical solution, the limiting member 3 is a groove structure for clamping with the housing of the ZYJ7 switch machine. During use, the groove is directly clamped on the housing of the ZYJ7 switch machine, which is convenient for use.

[0034] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
