Technical Field
[0001] The utility model relates to the technical field of railway line maintenance and repair, in particular to a railway line integral roadbed height adjustment pad. Background Art
[0002] The sinking of the entire roadbed of a railway line is one of the main common defects of railway lines. It will cause the line to have poor height, which can endanger driving safety in severe cases. At present, the main construction techniques used to deal with the poor height of the line caused by the sinking of the entire roadbed are as follows: a small amount of sinking can be handled by installing height-adjusting fasteners and pads; if the amount of sinking is large, it can be handled by grouting. Some railways even remove the entire roadbed and replace it with an ordinary gravel roadbed or repair the entire roadbed. The above treatment methods have complex construction processes, consume a lot of materials, have high construction costs, and are difficult to construct. In addition, the line construction must be blocked and driving must be interrupted during construction, affecting normal transportation and production. It has always been a difficult construction project to deal with the poor height of the line caused by the sinking of the entire roadbed. There is an urgent need to develop a new device that can simply and efficiently deal with the poor height caused by the sinking of the entire roadbed of a railway line. Utility Model Content
[0003] In order to solve the above technical problems, the utility model proposes a railway line integral roadbed height adjustment pad which is simple to construct, consumes less materials, and does not affect normal transportation and production.
[0004] The technical solution of the present utility model is achieved as follows:
[0005] A railway line integral track bed raising pad comprises a rail support plate and shoulders arranged at both ends of the rail support plate, circular holes for inserting spiral spikes are provided on both sides of the rail support plate, the shoulders are arranged into a parallelogram structure, the shoulders are arranged to be parallel to the side walls of the sleeper rail support groove, and when the rail support plate and the shoulders are placed in the sleeper rail support groove as a whole, the outer side surfaces of the shoulders are in contact with the side walls of the sleeper rail support groove.
[0006] Furthermore, the width of the rail supporting plate and the shoulder is adapted to the width of the rail supporting groove of the sleeper.
[0007] Furthermore, the height of the shoulder is greater than the depth of the sleeper rail groove.
[0008] Furthermore, the shoulder guard includes a first part fixedly arranged at the end of the rail support plate, a mounting groove is provided at the top of the first part, a second part is provided in the mounting groove, and an adjustment component for adjusting the height and inner and outer positions of the second part is provided between the first part and the second part.
[0009] Furthermore, the first part has a third part extending outward from both sides away from one end of the rail support plate and being sleeved on the side of the sleeper, and the third part is provided with a lifting groove, and the adjusting component includes a lifting plate slidingly arranged between the two lifting grooves in the height direction and an adjusting bolt threadedly connected to the lifting plate, and the inner end of the adjusting bolt is rotatably connected to the outer side surface of the second part.
[0010] Furthermore, the height of the inner bottom wall of the mounting groove is the same as the height of the upper surface of the rail support plate.
[0011] The utility model has the following beneficial effects:
[0012] 1. According to the sinking situation of the integral roadbed, the integral roadbed height adjustment pad of the railway line is padded in the sinking section of the integral roadbed, and then the integral roadbed and the integral roadbed height adjustment pad of the railway line are anchored to form a whole through the sleeper vertical bolts, which improves the supporting structure of the integral roadbed, thereby restoring the smoothness of the line and achieving the purpose of fundamentally solving the problem of line height difference.
[0013] Compared with the traditional method of repairing the sunken integral roadbed or grouting the sunken integral roadbed, the railway line integral roadbed raising pad avoids the need to consume a large amount of sand, gravel, cement, ballast and other materials during the excavation of the roadbed or grouting operation. On the other hand, the device can utilize the maintenance skylight for operation without blocking the line for construction, thus avoiding the economic losses caused by the interruption of traffic during the blocking construction and the impact on normal transportation production. It is a simple, efficient and practical device. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a structural diagram of the utility model;
[0015] Figure 2 It is a schematic diagram of the disassembly of the shoulder guard of the utility model. DETAILED DESCRIPTION
[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] like Figure 1 and Figure 2As shown, a typical embodiment of the present invention provides a railway line integral track bed height adjustment pad, comprising a rail supporting plate 1 and shoulders 2 arranged at both ends of the rail supporting plate 1, circular holes 3 for inserting spiral spikes are opened on both sides of the rail supporting plate 1, and the shoulders 2 are arranged into a parallelogram structure. The shoulders 2 are arranged to be parallel to the side walls of the sleeper rail supporting groove, and when the rail supporting plate 1 and the shoulders 2 are placed in the sleeper rail supporting groove as a whole, the outer side surface of the shoulders 2 is in contact with the side walls of the sleeper rail supporting groove.
[0018] In this embodiment, the height adjustment pad is prefabricated based on the sleeper type and the size of the sleeper rail groove. The width of the rail plate 1 and shoulder 2 matches the width of the sleeper rail groove, and the height of the shoulder 2 is greater than the depth of the sleeper rail groove. Before installing the height adjustment pad, it is necessary to prepare the extended concrete sleeper spiral spikes and spike anchors in advance. To ensure track elasticity after the height adjustment pad is installed, a prefabricated rubber pad based on the size of the height adjustment pad can be inserted between the sleeper and the height adjustment pad.
[0019] During installation, without affecting transportation production, drill holes at the locations of the existing sleeper spiral spike holes using the "drill one every two" method. Then, insert the height adjustment pads and rubber pads according to the height of the entire trackbed sinking area. After the height adjustment pads are correctly positioned, insert the spiral spikes for anchoring, so that the sleepers and height adjustment pads are connected to form a whole under the action of the anchoring agent. After 24 hours, when the anchoring agent is stable, check that the anchor bolts have passed the pullout test and then install the connecting parts. Repeat the above installation steps twice to complete the entire installation work.
[0020] On this basis, the shoulder guard 2 includes a first part 2.1 fixedly arranged at the end of the support rail plate 1, a mounting groove 2.2 is opened at the top of the first part 2.1, a second part 2.3 is arranged in the mounting groove 2.2, and an adjustment component for adjusting the height and internal and external positions of the second part 2.3 is arranged between the first part 2.1 and the second part 2.3.
[0021] By adjusting the second part 2.3 in the height direction so that the second part 2.3 is located on the top of the sleeper, and adjusting the second part 2.3 in the inward and outward directions, the original track clip can be maintained in the original position in the inward and outward directions. Thus, it can be avoided that after the height adjustment pad is added, the shoulder 2 occupies the space between the original track clip and the side wall of the rail groove, causing the original track clip to move inward compared to the original position. Thus, the position of the original track clip can be kept unchanged, thereby ensuring its fixing effect on the track.
[0022] The first part 2.1 has a third part 2.4 extending outward from both sides of one end of the rail support plate 1 and is sleeved on the side of the sleeper. The third part 2.4 is provided with a lifting groove 4. The adjustment component includes a lifting plate 6 slidingly arranged between the two lifting grooves 4 in the height direction and an adjusting bolt 5 threadedly connected to the lifting plate 6, and the inner end of the adjusting bolt 5 is rotatably connected to the outer side surface of the second part 2.3.
[0023] In practice, the second part 2.3 is directly supported on the rail sleeper by moving upward in the lifting groove 4 and then directly lowering it. The adjusting bolt 5 is then rotated to control the inner and outer positions of the second part 2.3 so that the inner surface of the second part 2.3 is in close contact with the outer surface of the original clip of the rail, thereby achieving a fixing effect.
[0024] The height of the inner bottom wall of the mounting groove 2.2 is the same as the height of the upper surface of the rail support plate 1.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
