[0022] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or prior art, and obviously, the following description of the drawing structure is only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained according to these drawings without creating creative labor.It needs to be explained here that the description of these embodiment modes is used to help understanding the utility model, but does not constitute the limitation to the utility model.

[0023] Embodiment:

[0024] As Figure 1 , Figure 2 And Figure 3 The embodiment provides a supporting horse stool for replacing elastic pad layer of ballastless track, including horse stool body 1, still including walking roller 2, arc-shaped supporting leg 3, sliding rod 4 and telescopic driver 5, two sliding rods 4 close to both ends of two length connecting rods 6 of horse stool body 1 are connected, the both ends of telescopic driver 5 are connected with two sliding rods 4 respectively, to drive two sliding rods 4 to slide to the direction close to each other or away from each other through telescopic driver 5, walking roller 2 is provided with four, the roller frame of each walking roller 2 is connected with the lower end of an arc-shaped supporting leg 3, to facilitate adjusting the height of walking roller 2 through arc-shaped supporting leg 3, the upper portion of each arc-shaped supporting leg 3 is provided with long strip sliding hole, and the long strip sliding hole extends along the length direction of arc-shaped supporting leg 3, each sliding rod 4 is matched and passes through two long strip sliding holes, so that sliding rod 4 can drive the upper portion of arc-shaped supporting leg 3 to move when sliding, the middle portion of each arc-shaped supporting leg 3 is rotatably connected with a positioning plate 7 fixed on length connecting rod 6, to ensure that the height of the middle portion of each arc-shaped supporting leg 3 is always unchanged, but the upper portion and lower portion of arc-shaped supporting leg 3 are driven around the middle portion, and when the upper portion of arc-shaped supporting leg 3 is swung by sliding rod 4, the lower portion of arc-shaped supporting leg 3 can swing walking roller 2, to realize the height adjustment of walking roller 2.

[0025] This invention controls the extension and retraction of the telescopic actuator 5, which allows the two sliding rods 4 to slide closer to or further away from each other. When the sliding rods 4 slide, they can cause the upper part of the arc-shaped support leg 3 to swing. Since the middle part of the arc-shaped support leg 3 is rotatably connected to the positioning plate 7, when the upper part of the arc-shaped support leg 3 swings, the lower part of the arc-shaped support leg 3 will also swing together, thus adjusting the height of the lower end of the walking roller 2 of the arc-shaped support leg 3. When the walking roller 2 is lowered, it can be supported on the ground, making it convenient to move the treadmill body 1. When the walking roller 2 is raised, it can be lifted off the ground without affecting the stability of the treadmill body 1.

[0026] As a preferred embodiment of this invention, it should be further explained that the upper end of the trestle body 1 is provided with rectangular or wedge-shaped square timbers, which support the lower end of the track bed slab and can play a role in shock absorption. Rectangular square timbers are suitable for track bed slabs of straight sections of track, while wedge-shaped square timbers are suitable for track bed slabs of curved sections of track.

[0027] As a preferred embodiment of this example, it should be further explained that the roller frame of each walking roller 2 is rotatably connected to the lower end of the corresponding arc-shaped support leg 3. When the telescopic actuator 5 retracts, the lower part of the arc-shaped support leg 3 is vertically set, and the walking roller 2 is supported on the ground. At the same time, the lower end of the treadmill body 1 leaves the ground, and the upper part of the arc-shaped support leg 3 is inclined from bottom to top toward the middle of the treadmill body 1. This allows the telescopic actuator 5 to move the treadmill body 1 when it retracts. This allows the walking roller 2 connected by the two slide rods 2 to be set at both ends as much as possible, making the treadmill body 1 more stable when it moves. Conversely, when the telescopic actuator 5 extends, the two walking rollers 2 retract inward and can always be located inside the treadmill body 1 without occupying extra space.

[0028] As a preferred embodiment of this invention, it should be further explained that each of the two width connecting rods 8 of the trestle body 1 is rotatably connected to a top rod 9. The end of the top rod 9 away from the width connecting rod 8 has an arc-shaped groove. When the telescopic actuator 5 retracts, the arc-shaped groove at one end of the top rod 9 abuts against the side of the slide rod 4 away from the telescopic actuator 5. Figure 3 As shown, the length of the arc-shaped groove is exactly one-quarter of the diameter of the slide rod 4, thus preventing the top rod 9 from falling off. Simultaneously, the top rod 9 also supports the slide rod 4, preventing it from moving towards either end of the trestle body 1, ensuring the stability of the slide rod 4 and reducing the force on the telescopic actuator 5. When the traveling roller 2 is supported on the ground and the trestle body 1 is moving, the top rod 9 is always under stress. Using the top rod 9 to support the slide rod 4 at this time prevents the telescopic actuator 5 from being constantly under stress and thus avoiding damage.

[0029] As one preferred embodiment in the embodiment, it needs to be explained further that two protrusions 10 are arranged on the upper end of the slide rod 4 corresponding to one end of each of the jacks 9, and the two protrusions 10 and the slide rod 4 form a U-shaped limiting slot, the width of the limiting slot is not less than the width of the jack 9, when the telescopic driver 5 is elongated, one end of the jack 9 can be placed in the U-shaped limiting slot, so that the jack 9 is also located inside the horse stool body 1 and does not interfere with the use of the horse stool body 1.

[0030] As one preferred embodiment in the embodiment, it needs to be explained further that the middle part of the upper end of the arc-shaped supporting leg 3 is provided with an avoiding slot, and the U-shaped limiting slot is provided with two, which are arranged in the same horizontal plane and correspond to one avoiding slot respectively, so that the overall structure design is more reasonable, one slide rod 4 can correspond to two jacks 9, and four jacks 9 in total can make the overall structure more stable.

[0031] As one preferred embodiment in the embodiment, it needs to be explained further that the two ends of the telescopic driver 5 are rotationally connected with the middle parts of the two slide rods 4, for example, sleeves are arranged at the two ends of the telescopic driver 5, so that the slide rods 4 can pass through the sleeves, which is simple and convenient to install.

[0032] As one preferred embodiment in the embodiment, it needs to be explained further that the telescopic driver 5 is a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, which can be selected according to actual conditions and is not limited specifically.

[0033] As one preferred embodiment in the embodiment, it needs to be explained further that the inner side of the length connecting rod 6 corresponding to each of the slide rods 4 is provided with a long slot, and the two ends of the slide rod 4 are respectively slidably connected in the two long slots, so as to ensure the stability of the slide rod 4 when sliding. It needs to be explained that the slide rod 4 can be a structure of a middle circular rod and two rectangular blocks, or the two ends of the slide rod 4 can be a T-shaped head structure, in which case the long slot is a corresponding T-shaped slot, which can be adjusted according to actual conditions.

[0034] Finally, it should be noted that the above only describes preferred embodiments of the utility model and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
