Description

Technical Field

[0001] The utility model relates to the technical field of high-speed rail train maintenance auxiliary equipment, in particular to an auxiliary tooling. Background Art

[0002] High-speed train maintenance is a necessary step to ensure the daily driving safety of high-speed trains. The maintenance personnel conduct regular maintenance on the mechanical structure, auxiliary equipment, braking system, traction and control system of the high-speed trains. In this process, it is necessary to measure the height of the coupler or other parts of the high-speed train. If the height is not appropriate, maintenance is required. If the auxiliary tooling only has the single function of measuring the height of the coupler, the tooling function is single and cannot perform auxiliary detection on whether the top surface height of the rail is tilted and whether it can meet driving safety. Moreover, when measuring whether the top surface of the rail is tilted, it is difficult to intuitively judge the tilt angle, and it is impossible to judge whether the tilt angle meets driving safety, making it difficult to assist in maintenance.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example: Please refer to the attached Figure 1 To Attachment Figure 6 :

[0032] The utility model proposes an auxiliary tooling, comprising: a main body 1 and a measuring plate 4; a clamping plate 101 is rotatably connected to the bottom of the main body 1 by setting a connecting shaft 1011, a rectangular hole 102 is opened inside the main body 1, and plug holes 103 are opened inside the main body 1 and on both sides of the front and rear of the rectangular hole 102; the clamping plate 101 is clamped on the rail to be detected; a measuring piece 2 is vertically clamped inside the rectangular hole 102; a connecting rod 51 is clamped inside the plug hole 103; a mounting seat 203 is fixedly welded on the right end surface of the measuring piece 2, a rotating shaft 6 is rotatably connected inside the mounting seat 203, an indicating needle 201 is welded on the front end surface of the measuring piece 2, and the internal movable clamp of the measuring piece 2 A height measuring piece 3 is connected; a measuring plate 4 is placed on the top surface of the main body 1, a rectangular through hole 401 is opened inside the measuring plate 4, the inside of the rectangular through hole 401 is penetrated by the measuring piece 2, a protractor 404 is fixedly bonded to the top surface of the measuring plate 4, a pointer 4041 is vertically set up on the rear side of the protractor 404 and the top surface of the measuring plate 4, when the measuring plate 4 and the measuring piece 2 are perpendicular to each other, the pointer 4041 and the indicator needle 201 overlap front and back, and the angle is zero; a sleeve 52 is sleeved on the outside of the connecting rod 51, and a roller 5202 is movably connected to the bottom of the sleeve 52 through an axis, and the bottom of the roller 5202 is attached to the top surface of the sleeper in the middle of the rail, and the connecting rod 51 and the sleeve 52 form a sleeve rod 5.

[0033] In the embodiments of the present disclosure, as shown in the attached Figure 3 As shown, a turning handle is welded on the front end face of the rotating shaft 6, and a gear 601 is coaxially fixedly connected to the rotating shaft 6. The gear 601 is meshingly connected with the rack plate 301. When the turning handle is turned, the rotating shaft 6 is driven to rotate, and the gear 601 is coaxially driven to rotate. The height measuring component 3 is moved up and down through meshing, and the height of the coupler or other components of the high-speed train is measured to assist in maintenance work.

[0034] In the embodiments of the present disclosure, as shown in the attached Figure 4 and attached Figure 6 As shown, the width of the rectangular through hole 401 is greater than the thickness of the measuring piece 2, the bottom surface of the support block 402 is connected to a contact wheel 4021 through an axis, and the front end surface of the measuring plate 4 is embedded with three sets of level gauges 403. The outer surface of the contact wheel 4021 is made of rubber material to increase the friction between the measuring plate 4 and the main body 1, ensuring that the measuring plate 4 will not slide after being placed on the top surface of the main body 1. The width of the rectangular through hole 401 is greater than the thickness of the measuring piece 2, so as not to affect the angle change caused by the skew of the measuring plate 4, ensuring accurate angle measurement. After the measuring plate 4 is placed on the top surface of the main body 1, if the measuring plate 4 is skewed, as shown in the attached Figure 6As shown, the angle ∠1 between the main body 1 and the standard horizontal plane CD is set to a skewed angle, and the heights of the two contact wheels 4021 are consistent, the measuring plate 4 and the main body 1 are parallel to each other, that is, CF∥BG, the angle between CF (the top surface of the measuring plate 4) and AB (the standard horizontal plane) is set to ∠2, the interior angles are equal, the corresponding angles are equal, and ∠2=∠1 is obtained, and the angle generated between the pointer 4041 and the indicator needle 201 is set to ∠4 The angle between the indicator needle 201 and the standard horizontal plane is set to ∠3, the dotted line (indicator needle 201) is a perpendicular line perpendicular to AB, ∠2+∠3=90°, and ∠3+∠4=90°, so ∠2=∠4 can be obtained. The angle generated between the pointer 4041 and the indicator needle 201 is the inclination angle ∠1 of the main body 1. The protractor 404 can be used to quantify whether the inclination angle of the top surface of the rail is within the driving standard to assist maintenance.

[0035] In the embodiments of the present disclosure, as shown in the attached Figure 3 As shown, a clamping plate 202 is welded on the left side of the measuring part 2, and the bottom surface of the clamping plate 202 is attached to the top surface of the main body 1. A through slot 204 is opened on the right end surface of the measuring part 2. The through slot 204 allows the height measuring part 3 to move up and down freely, so as to perform height detection on the coupler or other parts of the high-speed train. The clamping plate 202 can ensure that the measuring part 2 is vertically plugged into the main body 1 and will not fall off, and the indicator needle 201 is a fixed angle measurement standard. When an angle deviation occurs between the pointer 4041 and the indicator needle 201, it is determined that the top surface of the rail is uneven, so that timely maintenance can be carried out to ensure the driving safety of the high-speed train.

[0036] In the embodiments of the present disclosure, as shown in the attached Figure 3 As shown, the left and right end faces of the height measuring piece 3 are respectively engraved with scale lines 302, and the right end face of the height measuring piece 3 is welded with a rack plate 301, which is movably engaged in the interior of the through groove 204. When the height measuring piece 3 is moved up and down, the scale lines 302 can assist maintenance personnel in auxiliary measurement of the height of the coupler or other high-speed train components to be inspected.

[0037] In the embodiments of the present disclosure, as shown in the attached Figure 5 As shown, a clamping block 5101 is welded to the outer wall of the connecting rod 51, and a clamping slot 5201 is opened on the sleeve 52. The clamping block 5101 is movably clamped in the inside of the clamping slot 5201. The sleeve rod 5 can allow the main body 1 to move on the rail without being affected by the sleepers and does not affect the placement angle of the main body 1, thereby ensuring that the height or angle results of the auxiliary maintenance measurement are accurate.

[0038] In the embodiments of the present disclosure, as shown in the attached Figure 1 and attached Figure 2As shown, the front end face of the connecting shaft 1011 is connected to the connecting screw 1012 through threaded engagement, and the outer diameter of the front end nut of the connecting screw 1012 is larger than the outer diameter of the connecting shaft 1011. When the splint 101 is passed through the connecting shaft 1011, the rotational connection between the splint 101 and the main body 1 can be completed by screwing the connecting screw 1012, and the front and rear directions of the splint 101 are limited at the same time. After the main body 1 is placed on the rail to be inspected, the inner end face of the splint 101 will fit against the outer facade of the rail, which increases the stability of the placement of the main body 1, but does not affect the inspection and measurement results of the main body 1 that is skewed after placement.

[0039] The working principle of this embodiment is as follows: after the main body 1 is placed on the rail to be inspected, the inner end surface of the clamping plate 101 will be attached to the outer surface of the rail, and the measuring plate 4 will be placed on the top surface of the main body 1. After the handle is turned, the rotating shaft 6 is driven to rotate, and the gear 601 is driven to rotate coaxially, and the height member 3 is driven to move up and down through meshing, so as to measure the height of the coupler and assist in the inspection;

[0040] When the measuring plate 4 is skewed, the angle between the pointer 4041 and the indicator needle 201 is the inclination angle of the main body 1. The protractor 404 can be used to quantify whether the inclination angle of the top surface of the rail is within the driving standard to assist maintenance.
