Description

Technical Field

[0001] This utility model relates to the field of railway sleeper rebar cutting and separation technology, specifically, to a toothless saw plate-splitting device for railway sleeper rebar cutting. Background Technology

[0002] Currently, after the sleeper is formed and cured by casting a sleeper mold (comprising an outer shell, base plate, through plate, limiting partition, and reinforcing bars), demolding is required. During demolding, the limiting partition at the limiting through plate position is first removed, and then the two ends of the reinforcing bars are cut off with gas welding. Then, the sleeper casting mold is rotated 180 degrees by a flipping device, and several sleepers connected one after another are discharged together (at this time, the reinforcing bars are connected to multiple sleepers simultaneously). After discharge, the multiple sleepers are automatically transferred to the cutting station by conveyor rollers for reinforcing bar cutting to separate multiple sleepers into independent parts (the specific cutting part is the reinforcing bars covered by the limiting partition during the casting process, which are not covered by the concrete and are thus exposed).

[0003] Since the limiting plate has been removed before demolding, the plate and the reinforcing bar can move relative to each other (specifically, the plate moves outward away from the sleeper, while the inner side is limited by the sleeper). If the reinforcing bar at the original location of the limiting plate is cut directly, it may come into contact with the plate after it has moved and thus damage the plate. Therefore, there is currently no design that can effectively separate the plate to the saw blade side when cutting. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a toothless saw plate-splitting device for cutting railway sleeper reinforcement.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A toothed saw slitting device for cutting railway sleeper reinforcement bars includes a roller conveyor, a mounting plate, a first telescopic cylinder, a toothed saw, a connecting rod, a mounting shell, a slitting assembly, and a horn-shaped component. The mounting plate, which is L-shaped in shape, is fixed to one side of the roller conveyor. The first telescopic cylinder is fixed on the mounting plate and is connected to a toothless saw. The saw blade of the toothless saw is spaced apart from the roller conveyor of the roller conveyor. The connecting rod is fixed to the mounting plate and the connecting rod and the saw blade of the toothless saw are spaced apart; The mounting housing is connected to the connecting rod and is located in front of the saw blade; The panel assembly is housed within the mounting housing and can extend outwards; The bull horn is fixed to the mounting shell and is located above the uppermost steel bar to be cut and in contact with the through plate.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figure 1 and Figure 2 As shown, a toothless saw slitting device for cutting railway sleeper reinforcement bars includes a roller conveyor 1 (the roller conveyor is prior art and its working principle will not be described), a mounting plate 2, a first telescopic cylinder 3, a toothless saw 4, a connecting rod 5, a mounting shell 6, a slitting assembly 7, and a horn 8. The toothless saw 4 can be a ready-made product that is available on the market, without any model restrictions. It consists of a motor, a timing belt assembly, and a circular saw blade. The working principle is as follows: A toothed saw is a commonly used power tool in wrought iron processing, used to cut iron wire, pipes, and profiles. Its main components are an electric motor and a saw blade, connected by a belt or directly fixed to the motor shaft.

[0013] The cutting principle of a toothed saw is to use the high-speed rotation of the saw blade and the sharp corners of the grinding wheel particles to cut the object. At the same time, the worn particles fall off and new sharp particles are exposed, which are then used to cut by the wear of the grinding wheel itself.

[0014] The mounting plate 2, which is L-shaped, is fixed to one side of the roller conveyor 1; The first telescopic cylinder 3 is fixed on the mounting plate 2, and the first telescopic cylinder 3 is connected to the toothless saw 4. The saw blade of the toothless saw 4 is spaced apart from the roller conveyor 1. The connecting rod 5 is fixed on the mounting plate 2 and the connecting rod 5 and the saw blade of the toothless saw 4 are spaced apart; The mounting housing 6 is connected to the connecting rod 5 and is located in front of the saw blade; The panel assembly 7 is housed within the mounting housing 6 and can extend outwards; The bull horn 8 is fixed to the mounting shell 6 and is located above the uppermost steel bar to be cut and in contact with the through plate.

[0015] Specific implementation of the embodiments of this utility model, such as Figure 2 As shown, the partition assembly 7 includes a partition 71, a miniature telescopic cylinder 72, a storage slot 73, and a push plate 74. The partition 71 is fixed inside the mounting housing 6; Miniature telescopic cylinders 72 are symmetrically fixed on partition 71 (the two miniature telescopic cylinders 72 operate synchronously under the control of the controller). The storage slots 73 are symmetrically arranged on the mounting shell 6 and do not penetrate the mounting shell 6; The push plate 74 is located in the storage slot 73 and connected to the miniature telescopic cylinder 72.

[0016] Specific implementation of the embodiments of this utility model, such as Figure 2 As shown, the bull horn 8 includes a first inclined portion 81 and a second inclined portion 82. The inclination of the first inclined portion 81 is greater than that of the second inclined portion 82, and the end of the first inclined portion 81 is formed with a sharp corner. The second inclined portion 82 is connected to the mounting shell 6.

[0017] To improve the stability of the sleepers during the steel bar cutting process, further optimizations to the above-described embodiments are possible, such as... Figure 1 and Figure 3 As shown, the roller conveyor 1 is equipped with fixed frames 9 on both sides of the forward path of the toothless saw 4, and the fixed frames 9 are equipped with second telescopic cylinders 10, which are connected to lower pressure plates 11. To improve the friction between the lower pressure plate 11 and the sleeper surface and to prevent wear, the design is further refined by providing a rubber pad 12 on the lower pressure plate 11.

[0018] It should be noted that the roller conveyor 1, the first telescopic cylinder 3, the toothless saw 4, the miniature telescopic cylinder 72, and the second telescopic cylinder 10 are all electrically connected to the controller, which is shown in the figure without a number.

[0019] The working process of this utility model: First, the staff stands on one side of the roller conveyor 1 and then visually observes the specific conveying of the sleepers. When the exposed steel bar between the first and second sleepers reaches the cutting area, the roller conveyor 1 is manually stopped by the controller. After the roller conveyor 1 stops, the first telescopic cylinder 3 is controlled by the controller to drive the toothless saw 4 forward and close to the steel bar. The saw blade of the toothless saw 4 starts to operate. At this time, if the two through plates between the first and second sleepers move outward and close together (i.e., the gap between the two through plates is small), the horn 8 will pass through the gap between the two through plates and push the through plates to the sides to move closer to the sleepers (the two through plates between two adjacent sleepers will not be in a completely close state). Then the saw blade of the toothless saw 4 will not come into contact with any through plate and cause damage. In this way, the cutting process of the exposed steel bar between two adjacent sleepers can be achieved by the back and forth movement of the toothless saw 4. Based on this, in order to avoid the situation where the bull horn 8 pushes the plate inward to a certain area and then can no longer make contact to achieve stable plate separation, a plate separation component 7 is designed to ensure that the two plate-penetrating positions between two adjacent sleepers are stable and will not approach the saw blade of the toothless saw 4 during the subsequent steel bar cutting process. As a result, the plate-penetrating pushing distance range is further expanded. When the plate separation component 7 is not needed, it can be stored to avoid occupying too much space (the operation of the plate separation component 7 can be selectively activated).

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
