AI Technical Summary

Problems solved by technology

This structure has some problems. For example, the existing structure has buckle and no buckle sleeves that are easy to release during adjustment, and the fine-tuning operation cannot be achieved. For example, when the turnout indicates that the adjustment is completed, the inside of the male and female bushings is rusted. When the data changes suddenly after the adjustment of the turnout due to reasons such as poor tightening of the pressing nut, etc., and the anti-loosening and anti-loosening of the daily equipment all rely on the fastening nut and spring washer, when the tightening is not in place due to operation omissions and other reasons happened

Embodiment 1

[0033] Refer to the attached drawings below Figure 2-Figure 5 A switch machine described in Embodiment 1 represents a rod adjustment mechanism, which includes: a mounting seat 1 , a worm 2 , a worm wheel 3 and a screw 4 .

[0034] like figure 2 As shown, the worm 2 is rotatably mounted on the mounting seat 1; the worm wheel 3 is rotatably mounted on the mounting seat 1 and engages with the worm 2, and the worm wheel 3 is provided with a screw hole; In cooperation, the lead screw 4 is adapted to be connected with the indicator rod.

[0035] Specifically, the mounting seat 1 is provided with a cavity inside, and both the worm wheel 3 and the worm 2 are rotatably arranged in the cavity. The left end of the mounting seat 1 is provided with a first through hole, and the right end is provided with a second through hole. and the second through hole are both communicated with the cavity, the screw rod 4 passes through the second through hole and is threadedly matched with the scre...

Embodiment 2

[0044] Embodiment 2 is a further improvement of Embodiment 1. like Image 6 and Figure 7 As shown, in Embodiment 2, only one end of the worm 2 protrudes from the mounting seat 1, and the screw shaft 5 and the adjusting head 7 are both arranged at the same end of the worm 3, that is, the screw shaft is fixedly connected with the worm 2, and the screw shaft 5 is far away from the worm 2. An adjusting head 7 is provided at one end of the screw shaft, and a locking nut 6 is provided on the screw shaft 5. After tightening the locking nut 6, the worm 2 can be fixed, and after loosening the locking nut 6, the worm 2 can be rotated through the adjusting head 7, which In this structural form, since the screw shaft 5 and the adjusting head 7 are both arranged at the same end of the worm 3, the adjustment is more convenient and the structure is more compact.

[0045] In summary, this institution has the following characteristics:

[0046] 1. The worm gear 3 worm 2 structure is used t...

Abstract

The invention discloses a switch machine indication rod adjusting mechanism which comprises a mounting base, a worm, a worm gear and a lead screw. The worm is rotationally mounted on the mounting seat; the worm gear is rotationally mounted on the mounting seat and meshed with the worm, and a screw hole is formed in the worm gear; the lead screw is arranged in the screw hole in a penetrating mode and matched with the screw hole in a threaded mode, and the lead screw is suitable for being connected with an indication rod. The worm and gear structure is mainly used for replacing an original shaft sleeve structure with a buckle or without a buckle, the worm and gear structure has the large transmission ratio, the bearing capacity is high, transmission is stable and reliable, and particularly, the self-locking performance is achieved, so that the structural stability and safety are improved, and mechanical parts are simplified.

Description

technical field [0001] The present invention relates to the technical field of switch machines, in particular to an adjustment mechanism for indicating rods of a switch machine. Background technique [0002] With the continuous development of my country's high-speed railways, the requirements for the stability and safety of the existing turnout conversion equipment are getting higher and higher. On-site maintenance often needs to adjust the length of the rod of the switch machine to ensure that the switch machine shows a gap. meet the standards. [0003] Existing adjustment mechanism application occasions, adjustment structure such as figure 1 As shown in the figure, it means that the rod is screwed onto the buttoned and non-buttoned shaft sleeves on the circular hole of the screw joint, and the indication is adjusted by rotating the non-buttoned shaft sleeve to drive the buckled shaft sleeve to move on the display connecting rod. , and then use the nut to hold the non-buck...
