Description

Technical Field

[0001] This utility model belongs to the technical field of railway turnout maintenance tools, specifically a laser rapid positioning tool for auxiliary turnout locking frames. Background Technology

[0002] Turnouts are an important component of railway tracks, used by switch machines to switch the switch rails and enable train track changing. A locking frame (also called a locking iron or locking bracket) is installed between the switch machine's operating lever and the switch rail. This frame is used to mechanically lock the switch after it is switched into position. When the operating lever is fully extended, the locking frame "holds" the head of the lever, preventing the switch rail from rebounding due to train vibration. Inside the locking frame is a locking rod (in many cases, the locking frame and locking rod are collectively referred to as the locking device), which locks or unlocks using rollers or inclined surfaces. The centerline of the locking frame must be "aligned and parallel" to the centerline of the switch machine's operating lever; otherwise, the locking rod will jam, resulting in slow switching or even motor burnout and switch derailment.

[0003] Therefore, the installation accuracy of the locking frame directly affects the smoothness of the locking rod's sliding, the switching time, and the lifespan of the switch machine.

[0004] Currently, the common method for adjusting the position of the locking frame on-site is to use manual visual inspection, feeler gauge measurement, and multiple trial shaking. This method has the following shortcomings:

[0005] Reliant on experience: Requires high skill levels from operators, making it difficult for newcomers to master quickly;

[0006] Low efficiency: It requires repeated disassembly and reassembly and test shaking, with an average operation time of more than 30 minutes;

[0007] Large error: Human judgment is highly subjective, which often leads to vertical or horizontal deviations between the center line of the locking frame and the action rod, resulting in faults such as locking rod jamming, switch machine overcurrent, and contact burnout.

[0008] Safety hazards: The operation takes a long time, occupies the track window, and increases the risk of traffic accidents. Utility Model Content

[0009] To address the aforementioned problems in the existing technology, this utility model provides a laser rapid positioning tool for auxiliary turnout locking frames.

[0010] The technical solution adopted by this utility model is as follows: A laser rapid positioning tool for an auxiliary turnout locking frame includes a main column, on which a magnet is installed to align the reference plane A of the main column with the side of the switch machine's actuating rod. A laser calibrator groove is vertically installed on the main column, and a laser calibrator is installed on the laser calibrator groove. The laser calibrator can simultaneously emit mutually perpendicular vertical laser lines and horizontal laser lines.

[0011] Furthermore, a magnet fixing clip is detachably connected to the main column by screws for installing and fixing a magnet.

[0012] Furthermore, a second magnet is installed at the bottom of the laser calibrator, which can slide infinitely along the laser calibrator's slide groove and be magnetically positioned to match the locking frame at different positions.

[0013] Furthermore, a slide rail connector is fixedly connected to the slide rail of the laser calibrator, and the slide rail connector is fixedly connected to the main column by screws.

[0014] Furthermore, the length direction of the laser calibrator slide is orthogonal to the reference plane A, so as to ensure that the vertical laser line emitted by the laser calibrator is parallel to the reference plane A, and the horizontal laser line emitted by the laser calibrator is parallel to the length direction of the laser calibrator slide.

[0015] Furthermore, the reference plane A is parallel to the plane C of the main column, the plane B of the main column is perpendicular to the reference plane A, and the plane D of the laser calibrator slide is parallel to the plane B, so that the vertical laser line is parallel to the side of the switch machine's action rod, and the horizontal laser line is parallel to the mounting surface of the locking frame, thereby forming a spatial orthogonal reference to achieve rapid positioning of the locking frame.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] This auxiliary turnout locking frame laser rapid positioning tool uses a magnet mounted on the main column to align the reference plane A of the main column with the side of the switch machine's operating rod. Using the side of the switch machine's operating rod as a reference, and with the assistance of a laser calibrator, the reference can be quickly and accurately located, allowing for precise adjustment of the locking frame position. This ensures smooth sliding between the locking rod and the locking frame, reducing operation time, improving work efficiency, and saving labor costs. Simultaneously, it reduces the risk of turnout defects, increases the service life of the switch machine, and ensures smooth operation of the railway system. Attached Figure Description

[0027] The following is combined with Figures 1-4 This utility model will be described in detail.

[0028] Example

[0029] like Figure 1 , Figure 2 and Figure 3As shown, an auxiliary turnout locking frame laser rapid positioning tool includes a main column 1, which is a cuboid metal tubular structure. A reference plane A is used to mate with the side of the switch machine's actuating rod 7, plane B is perpendicular to reference plane A, and plane C is parallel to reference plane A. The main column 1 can be made of aluminum alloy profiles, which can significantly reduce the overall weight of the tool.

[0030] A magnet 3 is installed on the main pole column 1 to align the reference plane A of the main pole column 1 with the side of the switch machine's operating rod 7. A magnet fixing clip 2 is detachably connected to the main pole column 1 by screws to install and fix the magnet 3.

[0031] The magnet fixing clip 2 is a U-shaped metal clip structure that can be detachably connected to the reference plane A of the main pole column by screws. One end of its inner side is tightly fitted with the reference plane A of the main pole column 1, and the other end is a suspended end used to install and fix the magnet 3.

[0032] Magnet 3 is a neodymium iron boron strong magnet (attractive force ≥50N), which is fixed to the inner side of the clamp of the magnet fixing clamp 2 by screw connection. Its adsorption surface is flush with the reference plane A of the main rod column 1. It is used to tightly adsorb the reference plane A of the main rod column 1 to the side of the switch machine action rod 7, so as to realize the rapid fixing and reference positioning of the main rod column 1.

[0033] A laser calibrator slide 4 is vertically mounted on the main column 1. The laser calibrator slide 4 is an L-shaped metal slide structure. The length direction of the slide is orthogonal to the reference plane A of the main column 1. The slide has a plane D, which is parallel to the plane B of the main column 1. The laser calibrator slide 4 is made of iron to facilitate the subsequent magnetic attraction of the laser calibrator 5.

[0034] A laser calibrator 5 is installed on the laser calibrator slide 4. The laser calibrator 5 is an integrated laser emitting device that can simultaneously emit vertical and horizontal laser lines that are perpendicular to each other.

[0035] A second magnet is installed at the bottom of the laser calibrator 5. The second magnet is a neodymium iron boron strong magnet (attractive force ≥30N). It is fixed to the bottom of the laser calibrator 5 by screws. Its adsorption surface is tightly attached to the bottom of the laser calibrator slide 4. It is used to realize the infinite sliding of the laser calibrator 5 along the laser calibrator slide 4 and magnetic positioning at any position, so as to adapt to the installation position of different types of turnout locking frames 8.

[0036] A slide rail connector 6 is fixedly connected to the slide rail 4 of the laser calibrator. The slide rail connector 6 is fixedly connected to the main column 1 by screws. The slide rail connector 6 is a U-shaped metal plate structure, which is integrally welded to the back of the slide rail 4 of the laser calibrator. The slide rail connector 6 is sleeved on the opposite side of plane B of the main column 1, and is fixedly connected to the reference plane A and reference plane B by screws.

[0037] The length direction of the laser calibrator slide 4 is orthogonal to the reference plane A, so as to ensure that the vertical laser line emitted by the laser calibrator 5 is parallel to the reference plane A, and the horizontal laser line emitted by the laser calibrator 5 is parallel to the length direction of the laser calibrator slide 4.

[0038] The reference plane A is parallel to the plane C of the main column 1, the plane B of the main column 1 is perpendicular to the reference plane A, and the plane D of the laser calibrator slide 4 is parallel to the plane B, so that the vertical laser line is parallel to the side of the switch machine action rod 7 and the horizontal laser line is parallel to the mounting surface of the locking frame 8, thereby forming a spatial orthogonal reference to achieve rapid positioning of the locking frame 8.

[0039] Specific examples Figure 4 As shown, when using this auxiliary turnout locking frame laser rapid positioning tool:

[0040] Step 1: Attach the magnet clamp 2 to the side of the switch machine operating rod 7, ensuring that the reference plane A is fully in contact with the side of the switch machine operating rod 7.

[0041] Step 2: Move the laser calibrator 5 along the laser calibrator slide 4 so that the vertical laser line is roughly aligned with the longitudinal center of the locking frame 8.

[0042] Step 3: Observe the parallelism between the horizontal laser line and the upper edge of the locking frame 8. If the opening is greater than 1mm, loosen the fastening bolts of the locking frame 8 and use a pry bar to fine-tune the frame until the horizontal laser line coincides with the edge of the frame.

[0043] Step 4: Check again that the vertical laser line coincides with the longitudinal center line of the locking frame 8. After confirming that there is no deviation, tighten the bolts.

[0044] Step 5: Rotate the turnout twice to confirm that the switching is smooth and without obstruction. Remove the device to complete the operation.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
