Technical Field
[0001] The utility model relates to the technical field of sleepers, in particular to a device for adjusting and controlling a concrete surface of a ladder-shaped sleeper ballast bed. Background Art
[0002] A sleeper is a wooden or concrete component located under the railway track that supports the track and carries the train load. A trapezoidal sleeper is a type of sleeper with a trapezoidal cross-section that is wider at the top and narrower at the bottom. It helps provide a larger support area and increase the stability of the track.
[0003] The bottom of the trapezoidal sleeper is made of cast concrete. During the construction process, the height of the concrete surface needs to be controlled. Therefore, a special device is needed to determine the thickness of the concrete surface. The current device does not have the function of height adjustment, so it cannot be applied to trapezoidal sleepers of different thicknesses and has poor practicality. In order to solve the above technical problems, we have designed an adjustable device for controlling the concrete surface of the trapezoidal sleeper roadbed. Utility Model Content
[0004] The purpose of the utility model is to provide an adjustable device for controlling the concrete surface of a trapezoidal sleeper roadbed, which has the advantages of conveniently controlling the thickness of the concrete surface and being able to adjust the height, thereby improving practicality, and solves the problems of being inconvenient to control the thickness of the concrete surface, being unable to adjust the height, and having poor practicality.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for adjusting the concrete surface of a trapezoidal sleeper track bed, comprising a support rod, a bottom plate is welded to the bottom of the support rod surface, a grip rod is welded to the front side of the support rod, a sealing rubber sleeve is fixedly connected to the top of the support rod, a movable top rod is slidably connected to the top of the sealing rubber sleeve, and a positioning bolt is threadedly connected to the top of the front side of the support rod.
[0006] Preferably, the movable push rod comprises a push rod body, a telescopic slide rod is welded to the bottom of the push rod body, and a scale bar is provided on the surface of the left side of the telescopic slide rod.
[0007] Preferably, a mounting slot is provided at the top of the support rod, and a placement groove is provided at the top of the mounting slot.
[0008] Preferably, a positioning nut is welded to the top of the front side of the support rod, and the rear side of the positioning bolt passes through the positioning nut and the support rod in sequence.
[0009] Preferably, a scale value is provided on the top of the left side of the support rod, and a hanging ring is welded on the top of the front side of the grip rod.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] Pull the main body of the push rod upwards, and the telescopic slide rod will be pulled out from the support rod. The personnel will observe the value on the scale bar on the surface of the telescopic slide rod and add it to the value of the scale value. When the added value is the same as the value of the set thickness, tighten the positioning bolt to position the telescopic slide rod, hang the main body of the push rod on the trapezoidal sleeper, and place the bottom of the bottom plate on the concrete surface. In this way, the thickness of the concrete surface at the bottom of the trapezoidal sleeper can be controlled. At the same time, the height of the device can be adjusted to meet the use of different thicknesses and improve practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See also Figure 1-Figure 4 , a device for adjusting and controlling the concrete surface of a trapezoidal sleeper ballast bed, comprising a support rod 1, a bottom plate 2 is welded to the bottom of the surface of the support rod 1, a grip rod 6 is welded to the front side of the support rod 1, a sealing rubber sleeve 9 is passed through the top of the support rod 1 and fixedly connected, a movable top rod 3 is passed through the top of the sealing rubber sleeve 9 and slidably connected, a positioning bolt 4 is threadedly connected to the top of the front side of the support rod 1, and by setting the grip rod 6, the device has a hand-held function, which can facilitate personnel to hold the device for placement;
[0018] See also Figure 4 The movable push rod 3 includes a push rod body 12, a telescopic slide rod 14 is welded to the bottom of the push rod body 12, and a scale bar 13 is provided on the surface of the left side of the telescopic slide rod 14. By setting the scale bar 13, the function of convenient reading can be achieved, and the height of the device can be accurately controlled;
[0019] See also Figure 3The top of the support rod 1 is provided with an installation slot 10, and the top of the installation slot 10 is provided with a placement slot 8. By providing the placement slot 8, the function of convenient installation is provided, and the sealing rubber sleeve 9 can be conveniently installed. At the same time, the sealing rubber sleeve 9 can remove the concrete residue attached to the surface of the telescopic slide rod 14 to avoid entering the interior of the installation slot 10 and affecting the use;
[0020] See also Figure 3 A positioning nut 11 is welded on the top of the front side of the support rod 1, and the rear side of the positioning bolt 4 passes through the positioning nut 11 and the support rod 1 in sequence. By setting the positioning nut 11, the function of thread installation is provided, and the positioning bolt 4 can be conveniently threadedly installed;
[0021] See also Figure 1 A scale value 7 is provided at the top of the left side of the support rod 1, and a hanging ring 5 is welded at the top of the front side of the grip rod 6. By setting the scale value 7, the height of the support rod 1 can be determined, which is convenient for adding the value on the scale bar 13. By setting the hanging ring 5, the device can be conveniently hung on an object for easy storage.
[0022] When in use, the height of the device is adjusted according to the set thickness of the concrete surface at the bottom of the trapezoidal sleeper. The personnel rotates the positioning bolt 4 counterclockwise, and the positioning bolt 4 is unscrewed from the positioning nut 11, and then pulls the top rod body 12 upward, and the telescopic slide bar 14 at the bottom of the top rod body 12 is pulled out from the support rod 1. The personnel observes the value on the scale bar 13 on the surface of the telescopic slide bar 14, and then adds it to the value of the scale value 7, which is the height of the entire device. When the added value is the same as the value of the set thickness, the positioning bolt 4 is rotated clockwise to position the telescopic slide bar 14, and then the top rod body 12 is hung on the trapezoidal sleeper, and the bottom of the bottom plate 2 is placed on the concrete surface. In this way, the thickness of the concrete surface at the bottom of the trapezoidal sleeper can be controlled, and the height of the device can be adjusted at the same time, which can meet the use of different thicknesses and improve practicality.
[0023] In summary: the adjustable device for controlling the concrete surface of the trapezoidal sleeper track bed, through the coordinated use of the support rod 1, the base plate 2, the movable top rod 3, the positioning bolt 4 and the scale value 7, solves the problems of inconvenient control of the thickness of the concrete surface, inability to adjust the height and poor practicality.
