Description

Technical Field

[0001] The utility model relates to the technical field of subway construction, in particular to a railway track centerline centering adjustment device. Background Art

[0002] When carrying out railway construction or railway maintenance, it is necessary to measure the actual position coordinates of the center line of the track, so as to find out the problem and guide the adjustment of the rails. For example, in the patent number "CN102182123A" and the patent name "Centering device for track centerline ruler", the track centerline ruler is placed on the left and right rails, so that the left rail contact block and the right rail contact block are respectively in contact with the rail top surfaces of the left and right rails, and the left baffle and the right baffle are respectively stuck on the outside of the left and right rails. At the same time, under the action of the first spring, the left end of the lower left shaft contacts the rail, and the right end of the upper left shaft contacts the cone. Similarly, the right end of the lower right shaft contacts the rail, and the left end of the upper right shaft contacts the cone. Since the center of the spherical prism on the prism seat is located on the central axis of the cone, and the lengths of the left and right horizontal axes are the same, the point on the central axis of the cone also represents the middle position of the two rails, and the center of the spherical prism on the prism seat is located on the plane of the lower surface of the left rail contact block and the right rail contact block, that is, on the top plane of the two rails. Therefore, the coordinates of the center lines of the two rails can be obtained by measuring the spherical prism placed on the prism seat. However, the above structure still has the following problems in actual use:

[0003] The above structure contacts the top surfaces of the left and right rails through the left rail contact block and the right rail contact block respectively, and the coordinates of the center lines of the two rails can be obtained through the spherical prism on the prism seat. However, when the rails have height deviations, the above structure is not convenient for adjusting them, which leads to deviations in the center lines, thereby affecting the measurement effect.

[0004] Therefore, we proposed a railway track centerline adjustment device that can solve the above problems well. Utility Model Content

At the same time, the upper end of the connecting rod passes through the cross beam, and the upper end surface of the connecting rod is in a horizontal state with the upper end surface of the cross beam.

[0012] Preferably, the elastic force of the first return spring and the second return spring is smaller than the gravity of the sphere, and two groups of the second return spring and the slide rod are provided.

[0015] Preferably, a vertical plate is fixed to the upper end surface of the cross beam, and the vertical plate is arranged in an inverted "U" shape, and a plumb ball is fixed to the lower side surface of the vertical plate.

[0020] (3) When the ball is placed in the arc groove in the inner cavity, it will press the pressure rod to slide downward, so that the lower end of the pressure rod protrudes from the lower surface of the beam. At this time, it can be known that the beam is in a parallel state, which makes it easier to know the specific position of the ball;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0030] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problem in the prior art that when the rail has a height deviation, it is not convenient to adjust it, which leads to a deviation in the center line, thereby affecting the measurement effect, the following scheme is disclosed, including a crossbeam 1, and mounting plates 4 are fixed on both sides of the lower end surface of the crossbeam 1; it also includes: threaded rods 8 are arranged on both sides of the crossbeam 1, and the lower ends of the threaded rods 8 pass through the lower surface of the crossbeam 1 and are connected to the arc-shaped contact plates 9 with bearings, and a threaded connection structure is formed between the threaded rods 8 and the crossbeam 1; the arc-shaped contact plates 9 are fixedly connected to the crossbeam 1 through telescopic rods 10, and the telescopic rods 10 are provided in two groups, and each group of telescopic rods 10 is provided with two; an inner portion is opened in the middle of the crossbeam 1 The inner wall of the lower cross beam 1 of the inner cavity 11 is provided with an arc groove 13, and a pressure rod 14 is provided through the middle of the arc groove 13, and the pressure rod 14 is slidably connected with the cross beam 1 through a first return spring 15, and the two ends of the first return spring 15 are respectively fixed to the pressure rod 14 and the cross beam 1, a sphere 12 is placed inside the inner cavity 11, and slide rods 16 are provided on both sides of the inner cavity 11, and the slide rod 16 is slidably connected with the cross beam 1 through a second return spring 17, and the two ends of the second return spring 17 are respectively fixed to the slide rod 16 and the cross beam 1, two groups of mounting plates 4 are provided, and each group of mounting plates 4 is provided with two, and a connecting slider 6 is fixed to the upper end surface of the inner mounting plate 4;

[0032] First, place the crossbeam 1 on the track so that the mounting plate 4 on the lower end face of the crossbeam 1 is placed on the outer side of the track. At the same time, one group of mounting plates 4 will also drive the pulley 5 to contact the inner side of the track. Through the setting of the pulley 5, it is convenient to move the crossbeam 1 as a whole, and the vertical plate 2 can better position the crossbeam 1. When the ball 12 in the inner cavity 11 rolls to the left, it will push the left sliding rod 16 to slide to the left, so that the left end of the left sliding rod 16 squeezes the inclined block 18, so that the inclined block 18 drives the connecting rod 19 to rise, and then the highest point of the connecting rod 19 is higher than the parallel surface of the crossbeam 1. At this time, it means that the height of the left side of the track is lower than that of the right side. At this time, it is only necessary to rotate the left threaded rod 8 so that the threaded rod 8 drives the left arc-shaped contact plate 9 to descend, and then lift up the left side of the crossbeam 1, so as to achieve the effect of adjustment, so that it is convenient to adjust and observe when there is a height difference in the track;

[0033] Embodiment 2: Different from Embodiment 1, this embodiment facilitates observation of whether the beam 1 is tilted. Figure 3-Figure 4 The connecting slider 6 is slidably connected to the cross beam 1 through a pressure spring 7, and the two ends of the pressure spring 7 are respectively fixed to the connecting slider 6 and the cross beam 1. At the same time, a pulley 5 is fixedly installed on the outer side of the lower end of the inner mounting plate 4. A vertical plate 2 is fixed on the upper end surface of the cross beam 1, and the vertical plate 2 is arranged in an inverted "U" shape. A plumb ball 3 is fixedly arranged on the lower side of the vertical plate 2;

[0034] At the same time, when the ball 12 in the inner cavity 11 rolls to the right, the ball 12 pushes the right sliding rod 16 to slide to the right, so that the right end of the right sliding rod 16 squeezes the inclined block 18, so that the inclined block 18 drives the connecting rod 19 to rise, and then the highest point of the connecting rod 19 is higher than the parallel surface of the beam 1. At this time, it means that the height of the right side of the track is lower than that of the left side. At this time, it is only necessary to rotate the right threaded rod 8 so that the threaded rod 8 drives the right arc-shaped contact plate 9 to descend, thereby lifting the right side of the beam 1.

[0035] Embodiment 3: Different from Embodiment 2, in this embodiment, the staff observes whether the beam 1 is in a horizontal state, and it is convenient to obtain the center line position. For details, refer to Figure 1-Figure 5 , the inner end of the slide rod 16 penetrates into the inner cavity 11, and the outer end of the slide rod 16 is connected to the inclined block 18, and the upper end surface of the inclined block 18 is fixed with a connecting rod 19, and the upper end of the connecting rod 19 penetrates the cross beam 1, and the upper end surface of the connecting rod 19 and the upper end surface of the cross beam 1 are in a horizontal state, the elastic force of the first return spring 15 and the second return spring 17 is less than the gravity of the ball 12, and the second return spring 17 and the slide rod 16 are provided with two groups;

[0036] When the ball 12 is placed in the arc groove 13 in the inner cavity 11, the pressure rod 14 will be pressed to slide downward, so that the lower end of the pressure rod 14 will protrude from the lower surface of the beam 1. At this time, the beam 1 is in a parallel state. At the same time, the first return spring 15 on the outer side of the pressure rod 14 facilitates to drive the pressure rod 14 upward. At this time, the left and right side slide bars 16 are not in contact with the ball 12. At this time, the elastic force of the second return spring 17 can drive the left and right side slide bars 16 to reset, so that the outer ends of the left and right side slide bars 16 no longer apply thrust to the inclined block 18. At this time, the connecting rod 19 can be driven to slide downward by the weight of the inclined block 18 itself, so that the top end of the connecting rod 19 is in a horizontal state with the beam 1. The staff can observe that the beam 1 is in a horizontal state. At this time, the position of the center line can be obtained through the vertical ball 3 on the lower side of the vertical plate 2.
