Description

Technical Field

[0001] This utility model belongs to the technical field of guide plate fixing structure, specifically relating to a novel guide plate fixing structure. Background Technology

[0002] In the rail production process, the rough rolling process is the core step that determines the dimensional accuracy of the rail. The guide plate of the BD rough rolling mill, as a key component guiding the direction of the rolled piece and controlling its formation, directly affects the critical dimensional tolerances of the rail, such as the rail head width and rail web thickness. With the continuous improvement of the requirements for rail safety performance and operational stability in my country's high-speed railways, the range of critical dimensional tolerances for rails is being strictly limited to a smaller interval, which places higher demands on the fixing reliability of the guide plate.

[0003] Currently, based on the rolling characteristics of different rail products and the shape and size of the corresponding guide plate, a wedge-shaped groove of a fixed size is milled at the bottom of the guide plate, and a corresponding wedge-shaped boss is made on the fixed beam to ensure the fit size between the boss and the groove. In this way, the guide plate and the fixed beam are tightly connected, reducing the loosening of the guide plate driven by the rolling workpiece during the rolling process. This ensures the stability of the rolling process and improves the quality of the rail's external dimensions. However, the wedge-shaped structure direct fitting and fixing method still has the following defects: (1) The existing new guide plate fixing structure mills a wedge-shaped groove of a fixed size at the bottom of the guide plate, and a corresponding wedge-shaped boss is made on the fixed beam to ensure the fit size between the boss and the groove. However, in actual use, if the rolling workpiece deviates and hits the guide plate during the rolling process, the extrusion force of the wedge surface cannot resist the lateral impact load, and the guide plate will immediately produce horizontal displacement. This will cause the rolling workpiece to jam, the equipment to collide, and even cause production safety accidents such as shutdown. Therefore, we propose a new guide plate fixing structure. Utility Model Content

[0004] The purpose of this utility model is to provide a novel guide plate fixing structure to solve the problem that the guide plate fixing structure mentioned in the background art still causes the guide plate to move under impact, leading to production accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel guide fixing structure, comprising a guide plate and a fixing beam. The bottom surface of the guide plate is provided with a wedge-shaped groove, and a wedge-shaped protrusion is slidably connected inside the wedge-shaped groove. The wedge-shaped protrusion is welded to the top surface of the fixing beam. An installation cylinder is fixed to the side of the wedge-shaped groove by inlay. Multiple locking holes are provided in a linear array on the surface of the wedge-shaped protrusion. A locking pin is slidably connected inside the installation cylinder. One end of the locking pin is inserted into the corresponding locking hole. A pull rod is fixed to the other end of the locking pin by welding. A spring is sleeved on the outer wall of the pull rod, and the end of the pull rod passes through the end face of the installation cylinder.

[0006] Preferably, a limiting groove is formed on the bottom surface of the locking pin, and a limiting block is provided inside the limiting groove. The limiting block is fixed to the inner wall of the mounting cylinder by welding.

[0007] Preferably, the surface of the locking pin is provided with a guide hole, and a guide rod passes through the inside of the guide hole, with one end of the guide rod fixed to the inner wall of the mounting cylinder.

[0008] Preferably, there are six guide holes, and the six guide holes are arranged in a circular array about the central axis of the lock pin.

[0009] Preferably, the longitudinal sections of the mounting cylinder and the locking pin are both circular, and the central axes of the mounting cylinder and the locking pin coincide with each other.

[0010] Preferably, the end of the pull rod has a through hole, and a pull ring is suspended in the through hole.

[0011] Preferably, a reinforcing plate is welded to the connection between the mounting cylinder and the guide plate, and the reinforcing plate has a triangular cross-section.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By designing the locking pin, locking hole, mounting cylinder, spring, and pull rod, when the guide plate is slidably mounted on the wedge-shaped groove via the wedge-shaped protrusion, the locking pin is inserted into the corresponding locking hole on the surface of the wedge-shaped protrusion. At the same time, the spring applies an elastic squeezing force to the locking pin to prevent one end of the locking pin from separating from the locking hole. This utility model locks the horizontal position of the guide plate by inserting the locking pin into the locking hole, preventing accidental horizontal displacement that could cause the rolled piece to jam or the equipment to collide, thus reducing the risk of production accidents. The designed limiting groove and limiting block limit the sliding of the locking pin to prevent it from detaching from the mounting cylinder. The locking mechanism utilizes a design with guide holes and a guide rod. A circular array of guide holes is formed on the surface of the locking pin along its central axis. The guide rod passes through the guide holes and is fixed to the inner wall of the mounting cylinder, ensuring the locking pin slides smoothly along the axis and preventing misalignment of the locking holes due to pin offset. This ensures stable operation of the locking mechanism. A pull ring is connected to the pull rod, allowing fingers to be inserted to apply force and pull the rod, making locking and unlocking convenient and quick. A reinforcing plate is welded to the connection between the mounting cylinder and the guide plate, reinforcing the mounting cylinder and preventing loosening and cracking.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1 to 6This utility model provides a technical solution: a novel guide fixing structure, including a guide plate 1 and a fixing beam 6. A wedge-shaped groove 5 is formed on the bottom surface of the guide plate 1. A wedge-shaped protrusion 15 is slidably connected inside the wedge-shaped groove 5. The wedge-shaped protrusion 15 is welded to the top surface of the fixing beam 6. An installation cylinder 4 is inlaid and fixed to the side of the wedge-shaped groove 5. Multiple locking holes 9 are formed in a linear array on the surface of the wedge-shaped protrusion 15. A locking pin 8 is slidably connected inside the installation cylinder 4. One end of the locking pin 8 is inserted into the corresponding locking hole 9, and the other end of the locking pin 8 is welded and fixed to a pull rod 7. A spring is sleeved on the outer wall of the pull rod 7. The spring 12 and the end of the pull rod 7 pass through the end face of the mounting cylinder 4. Through the designed locking post 8, locking hole 9, mounting cylinder 4, spring 12 and pull rod 7, when the guide plate 1 is slidably mounted on the wedge groove 5 by the wedge protrusion 15, the locking post 8 is inserted into the locking hole 9 opened on the surface of the corresponding wedge protrusion 15. At the same time, the spring 12 applies an elastic squeezing force to the locking post 8 to prevent one end of the locking post 8 from separating from the locking hole 9. This utility model locks the horizontal position of the guide plate 1 by inserting the locking post 8 into the locking hole 9, avoiding accidental horizontal displacement, which could cause the rolled piece to jam or the equipment to collide, thus reducing the risk of production accidents.

[0024] In this embodiment, preferably, a limiting groove 10 is formed on the bottom surface of the locking pin 8, and a limiting block 11 is provided inside the limiting groove 10. The sliding of the locking pin 8 is limited by the designed limiting groove 10 and limiting block 11 to prevent the locking pin 8 from detaching from the mounting cylinder 4. The limiting block 11 is fixed to the inner wall of the mounting cylinder 4 by welding.

[0025] In this embodiment, preferably, the surface of the locking pin 8 is provided with guide holes 14, and a guide rod 13 passes through the inside of the guide holes 14. One end of the guide rod 13 is fixed to the inner wall of the mounting cylinder 4. There are six guide holes 14, and the six guide holes 14 are arranged in a circular array about the central axis of the locking pin 8. The longitudinal section of both the mounting cylinder 4 and the locking pin 8 is a circular structure, and the central axes of the mounting cylinder 4 and the locking pin 8 coincide with each other. Through the designed guide holes 14 and guide rods 13, six guide holes 14 arranged in a circular array along the central axis are opened on the surface of the locking pin. After the guide rod 13 passes through the guide holes 14, it is fixed to the inner wall of the mounting cylinder 4, ensuring that the locking pin 8 always slides smoothly along the axis, avoiding misalignment of the locking hole 9 due to the offset of the locking pin 8, and ensuring the stable operation of the locking mechanism.

[0026] In this embodiment, preferably, the end of the pull rod 7 has a through hole, and a pull ring 3 is suspended in the through hole. The pull ring 3 is connected to the pull rod 7 through the designed pull ring 3. A finger is inserted into the pull ring 3 to apply force to the pull rod 7 for pulling operation, making the locking and unlocking of this utility model convenient and quick.

[0027] In this embodiment, preferably, a reinforcing plate 2 is welded to the connection between the mounting cylinder 4 and the guide plate 1. The reinforcing plate 2 has a triangular cross-section. The reinforcing plate 2 is welded to the connection between the mounting cylinder 4 and the guide plate 1 to reinforce the mounting cylinder 4 and prevent loosening and cracking.

[0028] The working principle and usage process of this utility model are as follows: First, the wedge-shaped protrusion 15 is fixed to the top surface of the fixed beam 6 by welding, ensuring that the center line of the wedge-shaped protrusion 15 coincides with the center line of the fixed beam 6. Then, the wedge-shaped groove 5 opened on the bottom surface of the guide plate 1 is aligned with the wedge-shaped protrusion 15, and the guide plate 1 is pushed horizontally to make the wedge-shaped protrusion 15 slide into the wedge-shaped groove 5. Due to the "wider at the top and narrower at the bottom" characteristic of the wedge structure, the mating surface between the wedge-shaped protrusion 15 and the wedge-shaped groove 5 will generate a squeezing force, which restricts the vertical displacement of the guide plate 1, thus completing the initial fixation.

[0029] After the wedge pre-fixing is completed, the spring 12 inside the mounting cylinder 4 is in a naturally extended state. The elastic force of the spring 12 pushes the locking pin 8 to move along the axial direction of the mounting cylinder 4 until one end of the locking pin 8 is inserted into the locking hole 9 opened on the surface of the wedge protrusion 15. At this time, the cooperation between the locking pin 8 and the locking hole 9 can limit the horizontal displacement of the guide plate 1 and achieve complete fixation of the guide plate 1.

[0030] When the guide plate 1 needs to be replaced or adjusted, the operator pulls the pull ring 3 at the end of the pull rod 7. The pull rod 7 drives the locking pin 8 to move into the mounting cylinder 4 against the elastic force of the spring 12 until the locking pin 8 is completely disengaged from the lock hole 9. Then, the guide plate 1 is pushed in the opposite direction in the horizontal direction, so that the wedge-shaped groove 5 slides out from the wedge-shaped protrusion 15, thus completing the disassembly of the guide plate 1. After the adjustment is completed, the pull ring 3 is released, the spring 12 returns to its natural extension state, and the locking pin 8 is pushed back into the lock hole 9 to achieve locking again.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
