Description

Technical Field

[0001] The present invention relates to the technical field of subway track equipment, and in particular to an adaptive subway track anti-slip device and an operating method. Background Art

[0002] Rails are the main components of railways and subway tracks. Their function is to guide the wheels of locomotives and vehicles forward, bear the huge pressure of the wheels, and transmit it to the sleepers. Rails must provide a continuous, smooth and least resistant rolling surface for the wheels. At present, the standard lengths of rails are 12.5m and 25.0m. Extra heavy and heavy rails use 25.0m standard length rails, and other types of tracks can use 12.5m25.0m standard length rails. There are three types of curved shortened rails that are 40, 80, and 120mm shorter than the 12.5m standard rail, and three types that are 40, 80, and 160mm shorter than the 25.0m standard rail. Therefore, rails are often operated in non-operational scenarios (such as rail welding, grinding, etc.). In this scenario, the rails need to be limited and prevented from falling off (preventing the rails from flipping and falling off). When welding long rails, the rail ends are aligned for welding. The long rails are not fixed during the welding process. As long as the rails are not fallen off, there are two main types of rail fixing devices. The first type is fixed by welding, and the other type is fixed by bolts. The fixing clip is firmly fixed to the base plate or the bottom of the rail by welding; the main disadvantage of the welding method is that a supplementary component must be prepared and welded to a plane or flat plate, which increases the price of the fixing device; on the other hand, the device relies on the personal ability of the welder and the dexterous and skilled welding technology; the last disadvantage is that this device must have additional components. On the other hand, when galvanized parts are used in special circumstances, the discharge of different liquids must be prepared to ensure the galvanizing process. A Chinese patent discloses an anti-slip device for a subway track fixing clamp (authorization announcement number CN208023328U). The patent technology discloses an anti-slip device for a subway track fixing clamp, which effectively solves the problem that the fixing clamp is easy to loosen and inconvenient to adjust; the technical solution thereof includes a bottom plate, and the bottom plate has two left-right symmetrical L-shaped plates, the L-shaped plates can move left and right along the bottom plate, the L-shaped plates are composed of a horizontal transverse plate and a vertical plate matched with the transverse plate, and the bottom surfaces of the bottom plate and the L-shaped plates are provided with friction strips matched with each other, the transverse plate of the L-shaped plate is provided with a flat plate that can move left and right, and the vertical plate of the L-shaped plate is threadedly connected with a push rod, the inner end of the push rod can contact the flat plate, and the push rod is provided with a compression spring located between the flat plate and the vertical plate, and a cover plate is provided above the flat plate, and a plurality of vertical bolts are provided on the cover plate, and the bolts can connect the cover plate, the transverse plate and the flat plate together, and the outer side of each bolt is provided with an anti-loosening device that can be fixed on the cover plate. It can be seen that the existing rail fixing device is not applicable. The existing rail fixing device is mainly used to fix the rails in the operation scenario. For the non-operation scenario, the rails used in the subway track have different specifications and shapes. Each time during operation, they need to be fixed separately, which is very inconvenient to operate. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an adaptive subway track anti-slip device and an operating method, which can solve the problem of inconvenient operation of limiting and anti-slipping of different types of rails, meet the operating requirements of rail processing scenarios, and simplify the operation.

[0004] The objective of the present invention is achieved through the following technical solutions: An adaptive subway track anti-slip device includes a base for placing rails, and an anti-slip mechanism, wherein the anti-slip mechanism is composed of anti-slip components respectively arranged on both sides of the rails and used to fix the rails, the anti-slip components on both sides of the rails act synchronously, each anti-slip component includes a clamping frame slidably mounted on the base, an inner anti-slip block slidably mounted in the clamping frame, each inner anti-slip block is provided with a plurality of non-penetrating anti-slip holes on the side close to the rail, and each anti-slip hole is provided with an anti-slip piece, one end of the anti-slip piece is an elastic piece, and the other end of the anti-slip piece is a contact piece, the elastic piece is installed in the anti-slip hole, and the plurality of contact pieces located on both sides of the rails are in close contact with the rails along the outer wall of the rails when under pressure. The elastic piece is a compression spring, and the contact piece is a reinforcing steel rod, one end of the compression spring is fixedly mounted in the anti-slip hole, and one end of the compression spring is connected to the reinforcing steel rod.

[0005] It also includes a synchronous drive mechanism, which includes a bidirectional screw rod, a screw barrel mounted on both ends of the bidirectional screw rod, and force blocks are arranged on both ends of the screw barrel, and load-bearing frames are arranged on both sides of the clamping and moving frame, and force-bearing slots that are engaged with the force blocks are arranged on the load-bearing slots. The bidirectional screw rod is provided with a rotating wheel that drives the bidirectional screw rod to rotate, and the clamping and moving frames on both sides of the rail are driven to move synchronously toward the rail by rotating the rotating wheel. In the present application, the opening direction of the force-bearing slot is outward, that is, the opening of the force-bearing slot is in the direction away from the rail. Such a setting can ensure that the force blocks and the force slots are only subjected to force when the rotating wheel is rotated to move toward the rail. It is convenient for adjusting the position of the clamping and moving frame and the internal anti-slip block (force is only applied in one direction). When moving away from the rail, the force blocks and the force slots are not subjected to force, which is also convenient for disassembly. Among them, the thread on the bidirectional screw rod can be a thread in the same direction, or it can be composed of two sections of threads in opposite directions. When the threads on the bidirectional screw are set in the same direction, the rotation directions of the internal threads of the screw barrels at both ends can be set in opposite directions. When the threads on the bidirectional screw are set in opposite directions, the rotation directions of the internal threads of the screw barrels at both ends can be set in the same direction. The purpose is that when the rotating wheel is rotated, the bidirectional screw drives the screw barrels at both ends, and the rotation of the bidirectional screw is converted into the linear motion of the clamping and moving frame, so as to realize the synchronous action of the clamping and moving frame at both ends.

[0006] It also includes a pushing mechanism for driving the inner anti-slipping block to move, the pushing mechanism includes a pushing screw and gear teeth, the gear teeth are rotatably installed on the side wall of the inner anti-slipping block (bearings can be installed on the side wall), a penetrating threaded through hole is provided on the clamping and moving frame, the pushing screw rod passes through the threaded through hole, a turning handle is provided at one end of the pushing screw rod, the other end of the pushing screw rod is connected to the gear teeth and drives the rotation, the gear teeth are installed on the bearing and rotate with the bearing, and the pushing screw rod is connected to the central axis outside the gear teeth.

[0007] The inner anti-slip block is also provided with a locking mechanism, which is composed of a card plate and a positioning card. Card blocks are provided on both sides of the card plate. The inner anti-slip block is also provided with a card slot matching the card block. The card plate is also provided with a tooth-shaped groove matching the gear teeth. The inner anti-slip block is also provided with a positioning groove for installing the positioning card. The card plate is provided with a positioning hole corresponding to the positioning groove. It should be noted that the positions of the tooth-shaped groove, the positioning hole and the card blocks on both sides on the card plate can be determined according to actual conditions. Preferably, the tooth-shaped groove is located directly above the gear teeth, the card blocks are located on the left and right sides of the card plate, and the positioning hole is located above the tooth-shaped groove.

[0008] The rail has an I-shaped cross-section, and the anti-detachment holes are evenly arranged on the inner anti-detachment block. The rail head, rail waist and rail bottom of the rail are in close contact with contact pieces when under pressure. Due to the edge shape of the rail, in the present application, the edges on both sides of the rail can play a good limiting role, preventing the rail from flipping and detaching during welding or other operations. Rack rails for moving the clamping and moving frame are arranged on both sides of the base. The rack rails are connected by two sections of oblique tooth plates facing opposite directions, and traveling teeth that travel on the oblique tooth plates are arranged on both sides of the clamping and moving frame. It should be noted that other moving pairs can also be applied to the present invention, such as linear slide slider moving pairs, transmission chains and transmission belts, etc., which are not described one by one here. Preferably, a reset spring is also arranged between the traveling teeth and the inner wall of the clamping and moving frame to make the movement smoother.

[0009] A sliding groove for sliding the inner anti-slip block is arranged on the inner side of the clamping and moving frame, and sliding blocks matching the sliding groove are arranged on both sides of the inner anti-slip block.

[0010] An operating method of an adaptive subway track anti-slip device comprises the following steps: S101, evenly arranging a plurality of adaptive subway track anti-slip devices in a straight line, and placing the rail on a base and between two anti-slip components; S102, adjusting the position of the clamping and moving frame: moving the clamping and moving frame on the base until at least one contact piece on the inner anti-slip block contacts the rail; S103, adjusting the position of the inner anti-slip block: moving the inner anti-slip block on the clamping moving frame until all contact pieces on the inner anti-slip block are in contact with the rail; S104, position locking: after all the contact pieces on the inner anti-slip block are in contact with the rail, the inner anti-slip block is locked. After the inner anti-slip block is locked, adaptive anti-slip positioning of the rail is achieved. When under pressure, all the contact pieces on the inner anti-slip block are in close contact with both sides of the rail.

[0011] In the present invention, considering that in the non-operating scenario of the rail, the rail needs to be limited and prevented from falling off, so as to allow the rail not to fall off under stress. The present application mainly consists of two moving parts, one is the movement of the clamping frame on the base (to make adjustments over a larger distance, usually controlled at 5-10 cm), and the other is the movement of the inner anti-falling block on the clamping frame (to adjust the contact piece and the rail). At the same time, since the gear teeth are rotatably mounted on the side wall of the inner anti-falling block, and the other end of the pushing screw is connected to the gear teeth, the position of the gear teeth relative to the pushing screw is fixed. When the pushing screw is rotated, the distance between the pushing screw and the clamping frame is The threads are engaged, so the clamping frame moves, and the rotating screw moves along the clamping frame and pushes the inner anti-slip block to move toward the rail, so that the reinforcing steel rod is subjected to force on the subway track. One end of the stressed reinforcing steel rod compresses the compression spring, so that the reinforcing steel rod is tightened and close to the inside of the inner anti-slip block according to the shape of the outer wall of the rail, so as to achieve the effect of positioning in line with the shape of the rail. Then, the position of the inner anti-slip block can be locked by the locking mechanism, and the card plate can be inserted into the card slot to make the toothed groove mesh with the gear teeth, and then the positioning card can be inserted to lock it. After locking, an adaptive rail anti-slip structure is formed, and the rail will not flip over and fall off in any scenario.

[0012] The beneficial effects of the present invention are as follows: (1) a movable clamping and moving frame is arranged on the base, and a movable inner anti-slipping block is arranged on the clamping and moving frame, which can be suitable for rails of different specifications and solves the problem of inconvenient operation of limiting and anti-slipping of different types of rails, thereby simplifying the operation process; (2) a contact piece that can contact the rail head, rail waist and rail bottom of the rail is arranged on the inner anti-slipping block, thereby preventing the rail from flipping and falling off and can be suitable for different processing scenarios of the rail.
