Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of operating tools, in particular to an integrated rail sawing machine support. BACKGROUND

[0002] With the rapid development of high-speed railway and urban rail transit, the speed and quality requirements of rail transit construction are continuously improved. During rail laying and maintenance, the steel rails often need to be cut, thus various rail sawing machines are derived. The rail sawing machine usually comprises a grinding wheel, a rail sawing machine support frame and a support arm, wherein the rail sawing machine support frame in the prior art usually comprises two or more frame body structures, which are combined and assembled. The combination and assembly of several frame body structures are prone to generate large vibration, so that the grinding wheel generates cutting error during cutting. Moreover, the part of the support frame where the transmission device is installed is only a plate. Due to the tension force on the transmission device and the centrifugal force of the grinding wheel, the plate is prone to deformation during work, thereby further causing cutting deviation and low cutting precision, and the flatness cannot meet the requirement of 0.3mm. In addition, when the grinding wheel is worn, the purpose of one-cut-to-the-end cannot be achieved during cutting of the steel rail, so that the steel rail needs to be cut on both sides. During cutting on both sides, the rail sawing machine in the prior art can ensure that sparks are downward during cutting of the first side of the steel rail, but during cutting of the second side of the steel rail, the grinding wheel is turned over, so that sparks will be sprayed obliquely upward, which has a large safety hazard. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present utility model provides an integrated rail sawing machine support, so that the sparks can be downward during cutting on both sides of the steel rail on the basis of improving the rigidity of the rail sawing machine support, thereby improving the cutting precision and safety of the rail sawing machine.

[0004] The technical scheme of the present utility model is implemented as follows:

[0005] An integrated rail sawing machine support comprises a support body and a distance adjusting shaft sleeve.

[0006] The support body is a box body structure, the front part of which is a mounting part for mounting a grinding wheel assembly and a transmission part, and the inside of the support body is provided with a mounting seat, and the mounting seat is provided with a first through hole.

[0007] The distance adjusting shaft sleeve is mounted in the first through hole, and the two ends of the distance adjusting shaft sleeve extend outward, and the distances from the end faces of the two ends to the center of the grinding wheel are equal.

[0008] Preferably, a plurality of grooves are arranged at the positions of the mounting seat where the first through hole is not arranged, so as to form a reinforcing rib structure.

[0009] Preferably, a space for arranging the transmission part is left between the mounting seat and the inner wall of the support body.

[0010] Preferably, a reinforcing sleeve is arranged at the first side of the bracket body and at the hole opening of the first through hole.

[0011] Preferably, a second through hole is arranged at the mounting portion.

[0012] Preferably, a connecting piece for mounting the grinding wheel assembly is arranged at the end of the second through hole and at the first side of the mounting portion.

[0013] Preferably, a plurality of grooves are arranged on the inner wall of the bracket body.

[0015] Preferably, a cover plate is arranged at the second side of the bracket body.

[0016] Preferably, a reinforcing rib plate is arranged on the outer side of the reinforcing sleeve.

[0017] As can be seen from the above, in the integrated saw rail machine bracket of the present application, the saw rail machine bracket is designed as an integrated structure, thereby avoiding the vibration caused by split assembly, and by designing the bracket as a box body structure, the overall width and rigidity of the structure are improved, the cutting error caused by vibration or deformation is reduced, the precision of the saw rail machine in cutting the steel rail is improved, the flatness of the cutting plane can reach 0.3mm, and the actual demand can be met.

[0025] In order to make the technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0026] As shown in Figures 1 to 7 , the utility model provides a kind of integrated saw rail machine support, comprising: support body 1 and distance adjusting shaft sleeve 4;

[0027] The support body 1 is box body structure, its front part is the mounting portion 11 for installing abrasive wheel assembly and transmission component, its inside is provided with mounting seat 2, and first through-hole 22 is provided on mounting seat 2;

[0028] The distance adjusting shaft sleeve 4 is installed in first through-hole 22, and the two ends of distance adjusting shaft sleeve 4 extend outward, and the distance of the end face of its two ends to the center of abrasive wheel 100 is equal.

[0029] In the technical scheme of the utility model, the structure of integrated saw rail machine support is reasonably designed, and multiple frame body structures are not needed to assemble again;By setting support body 1 into box body structure, the support width is increased, so that the rigidity of saw rail machine support can be improved, deformation is not prone to occur, and cutting accuracy is guaranteed;By setting mounting seat in support body interior, the effect of local strength reinforcement can also be realized, and the reliability of distance adjusting shaft sleeve and support arm connection is guaranteed;Through the design of box body structure and local reinforcement, rigidity is strengthened without making weight too heavy.

[0030] By setting distance adjusting shaft sleeve 4, and making its first end 41 (the first end 41 of distance adjusting shaft sleeve refers to the end located on the same side with the first side 111 of mounting portion) and second end extend outward respectively, and making the distance of the end face of its two ends to the center of abrasive wheel equal, so that saw rail machine support arm can be installed on both sides of saw rail machine support using distance adjusting shaft sleeve 4, and cutting seam correspondence can be guaranteed when cutting on both sides.

[0031] For example, when cutting on both sides of steel rail, abrasive wheel 101 is installed on saw rail machine support. First refer to Figure 5 , the second end 42 of distance adjusting shaft sleeve on saw rail machine support 1 is connected with support arm fixed on steel rail, and then the first side of steel rail is cut, at this time, abrasive wheel 101 rotates downward (i.e. Figure 5The sparks generated by the cutting are also sprayed downward (the direction of the arrow in FIG. 8). After the first side of the rail is cut, the support arm is turned over, the second end 42 of the pitch adjusting shaft sleeve is removed from the support arm, the first end 41 of the pitch adjusting shaft sleeve on the rail saw support frame is connected with the support arm fixed on the rail, and then the second side of the rail is cut. At this time, since the mounting surface of the rail saw support frame is turned over, the rotating direction of the grinding wheel is still downward (the direction of the arrow in FIG. 9), so the sparks generated by the cutting are still sprayed downward. In the prior art, after the support arm is turned over, the rail saw support frame and the grinding wheel assembly are also turned over, so the direction of the grinding wheel is turned over and the grinding wheel rotates upward. Therefore, the sparks generated by the cutting are sprayed obliquely upward. Obviously, the design of the present application can significantly improve the safety and reduce the safety hazards. Figure 6 Figure 7 The support arm is turned over, the second end 42 of the pitch adjusting shaft sleeve is removed from the support arm, the first end 41 of the pitch adjusting shaft sleeve on the rail saw support frame is connected with the support arm fixed on the rail, and then the second side of the rail is cut. At this time, since the mounting surface of the rail saw support frame is turned over, the rotating direction of the grinding wheel is still downward (the direction of the arrow in FIG. 9), so the sparks generated by the cutting are still sprayed downward. In the prior art, after the support arm is turned over, the rail saw support frame and the grinding wheel assembly are also turned over, so the direction of the grinding wheel is turned over and the grinding wheel rotates upward. Therefore, the sparks generated by the cutting are sprayed obliquely upward. Obviously, the design of the present application can significantly improve the safety and reduce the safety hazards. Figure 6

[0032] In addition, during the cutting process, since the bottom end of the support arm is always clamped on the rail, even when the support arm is turned over, the fixed point of the support arm on the rail does not change. When the two ends of the pitch adjusting shaft sleeve 4 are installed on the support arm in sequence, in order to ensure that the cutting seams of the two sides of the rail cut by the grinding wheel correspond to each other, the two ends of the pitch adjusting shaft sleeve 4 are extended outward, and the distances from the end faces of the two ends to the center of the grinding wheel are equal, so as to ensure that the cutting seams of the two sides of the rail correspond to each other accurately during the cutting, and the cutting precision is ensured.

[0033] In the technical scheme of the present application, the integrated rail saw support frame can be implemented by using various implementation methods. The technical scheme of the present application will be described in detail below by taking one of the implementation methods as an example.
