Description
Technical Field
[0001] The utility model relates to the technical field of concrete sleeper clamps, in particular to a concrete sleeper cloth and pillow spacing clamp. Background Art
[0002] At present, the latest sleeper laying method in the railway industry is to use a sleeper changing machine to clamp and spread the sleepers. This method of laying sleepers controls the sleeper spacing by spreading white lime lines, and cannot forcibly constrain the sleeper spacing. When the sleeper changing machine is used for a long time or when a novice is operating to clamp the concrete sleepers, one side cannot be aligned with the white lime line indicating the spacing, resulting in a loss of sleeper spacing control, which greatly reduces the control accuracy of the concrete sleeper spacing. After laying the sleepers, it is necessary to manually adjust the spacing of the laid concrete sleepers again, affecting the overall efficiency of laying the sleepers. If the sleeper changing machine is used for laying the sleepers improperly, it may also cause the clamp of the sleeper changing machine to knock against the outer surface of the concrete sleeper, causing damage to the outer surface of the concrete sleeper, reducing the visual effect of the concrete sleeper, or even causing damage; moreover, when laying the sleepers, the sleeper changing machine needs to use white lime lines to sprinkle the side lines of the concrete sleepers and the lines indicating the concrete spacing, which requires a large number of personnel, many processes, and complicated auxiliary work.

[0031] like Figure 1 , Figure 2 As shown, the utility model includes a limiting horizontal beam 2 and a limiting vertical beam 3. The limiting horizontal beam 2 is horizontally arranged, and the number of the limiting vertical beams 3 is multiple. The multiple limiting vertical beams 3 are spaced apart on the lower side of the limiting horizontal beam 2. The top of each limiting vertical beam 3 is connected to the bottom of the limiting horizontal beam 2. The side where two adjacent limiting vertical beams 3 are close to each other is inclined outward to facilitate the fitting of the limiting vertical beam 3 with the concrete sleeper 6.
[0032] The spacing between two adjacent limiting vertical beams 3 is used to limit the distance between the ends of two adjacent concrete sleepers 6, so the limiting vertical beams 3 can control the placement of the concrete sleepers 6. The inclination angle of the limiting vertical beam 3 is consistent with the inclination angle of the side wall of the concrete sleeper 6, so that the limiting vertical beam 3 and the side wall of the concrete sleeper 6 fit closely. The length of the limiting horizontal beam 2 is the distance between the two adjacent concrete sleepers 6, the number of the limiting vertical beams 3 is two, the two limiting vertical beams 3 are respectively welded to the left and right ends of the limiting horizontal beam 2, the sides of the two limiting vertical beams 3 facing each other are both inclined outward, the sides of the two limiting vertical beams 3 away from each other are both perpendicular to the horizontal plane, and the spacing between the two limiting vertical beams 3 is the spacing between the ends of the two adjacent concrete sleepers 6 away from each other. When in use, the first concrete sleeper 6 and the second concrete sleeper 6 are placed at the starting point of the pillow, and the placement position of the first concrete sleeper 6 and the second concrete sleeper 6 is a preset position, which is a position planned in advance, and the vertical distance between the ends of the first concrete sleeper 6 and the second concrete sleeper 6 is a preset distance, which is the distance between two adjacent concrete sleepers 6 planned in advance, and the limiting crossbeam 2 of the first pair of concrete sleeper spacing fixture 11 is horizontally placed in the middle position of the two bolt holes 9 of the rail support platforms 10 at both ends of the first concrete sleeper 6 and the second concrete sleeper 6, and the limiting crossbeam 2 is respectively fitted with the top wall of the first concrete sleeper 6 and the top wall of the second concrete sleeper 6, and the limiting vertical beams 3 at both ends of the limiting crossbeam 2 are close to the right inclined surface of the first concrete sleeper 6 and the left inclined surface of the second concrete sleeper 6, respectively. Since the close side of the two limiting vertical beams 3 is an outward inclined surface, The limiting vertical beam 3 can fit closely with the concrete sleeper 6, and the concrete sleeper 6 is transported by the forklift 7. When the forklift 7 approaches the second concrete sleeper 6, the second pair of concrete sleeper spacing fixtures 12 are placed in the middle of the two bolt holes 9 of the rail support platform 10 at both ends of the second concrete sleeper 6 and the third concrete sleeper 6, respectively. The forklift 7 slowly moves backward and pulls the third concrete sleeper 6 backward. Under the reaction force of the limiting vertical beam 3, the third concrete sleeper 6 slides down the forklift 7. The distance between the left wall of the third concrete sleeper 6 and the right wall of the second concrete sleeper 6 is the distance between the two limiting vertical beams 3 at both ends of the limiting horizontal beam 2. Therefore, the distance between the first concrete sleeper 6 and the second concrete sleeper 6 is the same as the distance between the second concrete sleeper 6 and the third concrete sleeper 6. By analogy, the distance between any two adjacent concrete sleepers 6 can be limited by the concrete sleeper spacing fixture to ensure that the concrete sleepers 6 are evenly arranged. The concrete sleeper spacing fixture is easy to operate, can improve the efficiency of pillow swinging, and reduce the spacing error between two adjacent concrete sleepers 6.
[0033] In another possible embodiment, a first limiting vertical beam 3 is set at the end of the limiting horizontal beam 2, and then a second limiting vertical beam 3 is set along the length direction, the side where the first limiting vertical beam 3 and the second limiting vertical beam 3 are close to each other is inclined outward, and the distance between the first limiting vertical beam 3 and the second limiting vertical beam 3 is the distance between the sides of two adjacent concrete sleepers 6 that are far away from each other, and then a third limiting vertical beam 3 is set on the side where the second limiting vertical beam 3 is close to the first limiting vertical beam 3, the distance between the second limiting vertical beam 3 and the third limiting vertical beam 3 is the width of the concrete sleeper 6, the side where the third limiting vertical beam 3 is close to the second limiting vertical beam 3 is inclined outward, and a fourth limiting vertical beam 3 is set on the side where the second limiting vertical beam 3 is away from the third limiting vertical beam 3, the side where the fourth limiting vertical beam 3 is close to the third limiting vertical beam 3 is inclined outward, and the distance between the fourth limiting vertical beam 3 and the third limiting vertical beam 3 is the distance between the sides of two adjacent concrete sleepers 6 that are far away from each other, and so on. Multiple limiting vertical beams 3 can be set on top to limit the spacing of the concrete sleepers 6. When in use, place the first concrete sleeper 6 and the second concrete sleeper 6 at the starting point of the sleeper, the first concrete sleeper 6 and the second concrete sleeper 6 are placed in standard positions, and the limiting crossbeams 2 of a pair of concrete sleeper-sleeper spacing fixtures are horizontally placed in the middle positions of the two bolt holes 9 of the rail support platforms 10 at both ends of the first concrete sleeper 6 and the second concrete sleeper 6. Here, the installation of a concrete sleeper-sleeper spacing fixture is described in detail, and the other concrete sleeper-sleeper spacing fixture is installed simultaneously. The first limiting vertical beam 3 of the concrete sleeper-sleeper spacing fixture is tightly attached to the right side wall of the first concrete sleeper 6, the second limiting vertical beam 3 is tightly attached to the left side wall of the second concrete sleeper 6, and the third limiting vertical beam 3 is tightly attached to the right side wall of the second concrete sleeper 6, that is, the first limiting vertical beam 3 and the second limiting vertical beam 3 limit the distance between two adjacent concrete sleepers 6, and the second limiting vertical beam 3 and The third limiting vertical beam 3 clamps the second concrete sleeper 6, and the concrete sleeper 6 is transported by the forklift 7. After the forklift 7 approaches the second concrete sleeper 6, the fourth limiting vertical beam 3 is pressed against the left side wall of the third concrete sleeper 6, and the fifth limiting vertical beam 3 is pressed against the right side wall of the third concrete sleeper 6. The limiting cross beam 2 between the fourth limiting vertical beam 3 and the fifth limiting vertical beam 3 is located in the middle position of the two bolt holes 9 of the rail support platform 10 at the end of the third concrete sleeper 6. The limiting cross beam 2 is pressed against the third concrete sleeper 6, and the forklift 7 slowly moves backward and pulls the third concrete sleeper 6 backward. Under the reaction force of the limiting vertical beam 3, the third concrete sleeper 6 slides off the forklift 7, and the distance between the first concrete sleeper 6 and the second concrete sleeper 6 is the same as the distance between the second concrete sleeper 6 and the third concrete sleeper 6. And so on, the spacing between any two adjacent concrete sleepers 6 can be limited.
[0034] The limiting beam 2 includes a first limiting beam 201 and a second limiting beam 202. The first limiting beam 201 is provided with a plurality of first threaded holes 15, and the plurality of first threaded holes 15 are spaced in groups of two near the end of the second limiting beam 202. The second limiting beam 202 is provided with a plurality of second threaded holes 16 with the same aperture, and the plurality of second threaded holes 16 are spaced in groups of two along the length direction of the second limiting beam 202. The first limiting beam 201 and the second limiting beam 202 are fastened and connected by bolts 4.
[0035] Four first threaded holes 15 are provided at the end of the first limiting beam 201 near the second limiting beam 202, and the four first threaded holes 15 are arranged in two rows in pairs, and the second limiting beam 202 is evenly provided with a plurality of second threaded holes 16 along its length direction, and the plurality of second threaded holes 16 are arranged in two rows on the second limiting beam 202. When adjusting the relative position of the first limiting beam 201 and the second limiting beam 202, the four bolts 4 are screwed out, and the second limiting beam 202 is moved in a direction close to or away from the first limiting beam 201. After moving to the target position, the four bolts 4 are respectively passed through the four first threaded holes 15 on the first limiting beam 201 and then inserted into the second threaded holes 16 at the corresponding positions on the second limiting beam 202, and the four bolts 4 are respectively screwed into the four second threaded holes 16. Then, the position adjustment of the first limiting beam 201 and the second limiting beam 202 is completed, and the concrete sleeper cloth and pillow spacing fixture can be put into use.
[0036] During construction, the relative positions of the first limiting beam 201 and the second limiting beam 202 are adjusted according to the requirements of the spacing between the concrete sleepers 6, so that the distance between the ends of the first limiting beam 201 and the second limiting beam 202 that are far away from each other meets the requirements of the spacing between the concrete sleepers 6, and the limiting vertical beam 3 connected to the first limiting beam 201 and the limiting vertical beam 3 connected to the second limiting beam 202 are both tightly attached to the side walls of the concrete sleepers 6, thereby limiting the spacing between the two concrete sleepers 6. By adjusting the relative position between the first limiting beam 201 and the second limiting beam 202, the applicability of the concrete sleeper spacing fixture can be improved.
[0037] The concrete sleeper cloth and pillow spacing fixture further comprises a handle 1, which is arranged on the first limiting crossbeam 201 and welded to the first limiting crossbeam 201 to facilitate taking the concrete sleeper cloth and pillow spacing fixture.
[0038] The handle 1 is convenient for lifting the concrete sleeper spacing fixture after limiting the placement position of the concrete sleeper 6, and placing the concrete sleeper spacing fixture on two adjacent concrete sleepers 6 to limit the placement position of the next concrete sleeper 6.
[0039] The bolt 4 is provided with a spring washer.
[0040] The first limiting beam 201 and the second limiting beam 202 are fastened and connected by four bolts 4 with spring washers. When the width of the concrete sleeper spacing fixture needs to be adjusted, the four bolts 4 are screwed out of the first limiting beam 201 and the second limiting beam 202, the relative position of the first limiting beam 201 and the second limiting beam 202 is adjusted, the second limiting beam 202 is pulled outward or inserted into the first limiting beam 201, and after adjusting to the target position, the four bolts 4 are screwed into the first limiting beam 201 and the second limiting beam 202 again, so that the first limiting beam 201 and the second limiting beam 202 are fixed, and the width adjustment of the concrete sleeper spacing fixture is completed. The spring washers are arranged on the bolts 4 to prevent the bolts 4 from scratching the first limiting beam 201 and the second limiting beam 202.
[0041] The handle 1 is provided with an anti-slip cover 5 .
[0042] An anti-slip cover 5 is provided on the handle 1 to facilitate taking the concrete sleeper cloth and the sleeper spacing fixture when laying the concrete sleepers 6.
[0043] Patches 8 are welded at the connection gaps between the two end portions of the limiting horizontal beam 2 along the length direction and the limiting vertical beam 3 .
[0044] The limiting horizontal beam 2 is welded to the limiting vertical beam 3, and a patch 8 is welded at the welding position of the limiting horizontal beam 2 and the limiting vertical beam 3 to avoid scratching the staff at the welding position of the limiting horizontal beam 2 and the limiting vertical beam 3, and at the same time, the welding effect of the limiting horizontal beam 2 and the limiting vertical beam 3 can be strengthened.
[0045] The height of the limiting vertical beam 3 matches the height of the concrete sleeper 6. This is convenient to ensure that the limiting cross beam 2 can be closely attached to the top of the concrete sleeper 6.
[0046] A rubber gasket is arranged at the bottom of the limiting horizontal beam 2, and a rubber gasket is arranged on the adjacent sides of two adjacent limiting vertical beams 3.
[0047] The rubber gasket can prevent the limit horizontal beam 2 and the limit vertical beam 3 from scratching the concrete sleeper 6 when the concrete sleeper spacing fixture is moved, and can also improve the tightness of the limit horizontal beam 2, the limit vertical beam 3 and the concrete sleeper 6.
[0048] When in use, the relative position between the first limiting cross beam 201 and the second limiting cross beam 202 is adjusted according to the laying requirements and the specifications of the concrete sleepers 6, so that the length of the limiting cross beam 2 meets the spacing requirements of the concrete sleepers 6. Since the limiting vertical beams 3 are respectively welded to the ends of the first limiting cross beam 201 and the second limiting cross beam 202 that are far away from each other, and the inclined sides of the limiting vertical beams 3 are arranged facing each other, the distance between the two limiting vertical beams 3 is the distance between the sides of two adjacent concrete sleepers 6 that are far away from each other. The first concrete sleeper 6 and the second concrete sleeper 6 are placed in a standard position. The limiting crossbeam 2 of the first pair of concrete sleeper cloth-sleeper spacing fixtures 11 are horizontally placed in the middle of the two bolt holes 9 of the rail support platforms 10 at both ends of the first concrete sleeper 6 and the second concrete sleeper 6, respectively. The limiting vertical beams 3 of the first pair of concrete sleeper cloth-sleeper spacing fixtures 11 are respectively attached to the side walls of the two concrete sleepers 6 on the far side. After the forklift 7 transports the concrete sleeper 6 close to the second concrete sleeper 6, the second pair of concrete sleeper cloth-sleeper spacing fixtures 12 are respectively placed on the second concrete sleeper 6 and the third concrete sleeper 6. At the middle position of the two bolt holes 9 of the rail bearing platforms 10 at both ends, the backward force of the forklift 7 is used to cause the limiting vertical beam 3 to generate an opposite force to drag the third concrete sleeper 6 out of the forklift 7. Similarly, a third pair of concrete sleeper spacing fixtures 13 are placed at both ends of the third and fourth concrete sleepers 6, and a fifth pair of concrete sleeper spacing fixtures 14 are placed at both ends of the fifth and sixth concrete sleepers 6. The forklift 7 continues to move backward until all concrete sleepers 6 fall to the ground. The distance between two adjacent concrete sleepers 6 is constrained by the limiting vertical beam 3 to meet the spacing requirement required for construction, thereby improving the construction efficiency.
[0049] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural transformation made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
