DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: a rail gripper with good stability for elevator installation, which includes a rail gripper housing 1. A bidirectional threaded rod 2 passes through the rail gripper housing 1 and is rotatably connected at the penetration point. A rotating block 3 is fixed on the right side of the bidirectional threaded rod 2. The bidirectional threaded rod 2 passes through a clamping jaw 4 and is threadedly connected at the penetration point. The rail gripper housing 1 is provided with a stabilizing device 5, and the clamping jaw 4 is provided with a positioning and clamping device 6.
[0023] The above-mentioned stabilizing device 5 includes a moving block 51, a first hinge rod 52, a second hinge rod 53, a limiting plate 54, a positioning plate 55 and a guiding column 56. The bidirectional threaded rod 2 passes through the moving block 51 and is threadedly connected at the penetration point. The outer wall of the moving block 51 is in contact with the inner wall of the rail gripper housing 1. The rotating block 3 drives the bidirectional threaded rod 2 to rotate. Since the moving block 51 is in contact with the inner wall of the rail gripper housing 1, the bidirectional threaded rod 2 can only drive the moving block 51 to move. The upper end of the first hinge rod 52 is hinged to the bottom surface of the left moving block 51. When the moving block 51 moves to the right, it drives the first hinge rod 52 to move to the right and simultaneously rotates around the hinge point between the first hinge rod 52 and the left moving block 51. One end of the first hinge rod 52 away from the moving block 51 is hinged to a second hinge rod 53. One end of the second hinge rod 53 away from the first hinge rod 52 is hinged to the bottom surface of the right moving block 51. When the right moving block 51 moves to the left, it drives the second hinge rod 53 to move to the left and simultaneously rotates around the hinge point between the second hinge rod 53 and the right moving block 51. The hinge point of the first hinge rod 52 and the second hinge rod 53 is simultaneously hinged with a limiting plate 54. When the first hinge rod 52 and the second hinge rod 53 rotate, the included angle between the first hinge rod 52 and the second hinge rod 53 becomes smaller, driving the limiting plate 54 to move along the direction of the guiding column 56. Positioning plates 55 are fixed on both sides of the limiting plate 54. When the limiting plate 54 moves downward, it drives the positioning plates 55 to move downward. A guiding column 56 is fixed on the upper surface of the limiting plate 54. The guiding column 56 passes through the rail gripper housing 1 and is slidably connected at the penetration point. This stabilizing device 5 can press the rail from above during use, making the rail work more stably in the rail gripper, avoiding excessive wear caused by collision during shaking and affecting the service life.
[0024] The above positioning and clamping device 6 includes a movable groove 61, a sliding groove 62, a sliding block 63, a spring 64 and a clamping block 65. The movable groove 61 is formed on the clamping jaw 4, and the sliding groove 62 is formed on the bottom surface of the limiting plate 54. The sliding block 63 slides on the inner wall of the sliding groove 62. When the limiting plate 54 moves downward, it drives the sliding block 63 to move. The spring 64 is fixed to the bottom surface of the sliding block 63. When the sliding block 63 moves, it drives the spring 64. One end of the spring 64 away from the sliding block 63 is fixed with the clamping block 65. When the spring 64 moves, it drives the clamping block 65. The clamping block 65 is slidably connected to the movable groove 61. When the positioning plate 55 continues to move downward, it pushes the clamping block 65 to slide along the inclined surface to clamp the rail. This positioning and clamping device 6 can position the rail during installation, making the installation more convenient. At the same time, during use, it can clamp and fix the rail, reducing the sliding caused by accidental thrust.
[0025] Working principle: Rotate the rotating block 3, the rotating block 3 drives the bidirectional threaded rod 2 to rotate. The rotation of the bidirectional threaded rod 2 drives the two groups of moving blocks 51 to approach each other. The left moving block 51 moves to the right, driving the first hinge rod 52 to move to the right and rotate around the hinge point of the first hinge rod 52 and the left moving block 51 at the same time. The right moving block 51 moves to the left, driving the second hinge rod 53 to move to the left and rotate around the hinge point of the second hinge rod 53 and the right moving block 51 at the same time. The first hinge rod 52 and the second hinge rod 53 rotate, reducing the angle between the first hinge rod 52 and the second hinge rod 53, and driving the limiting plate 54 to move along the direction of the guide post 56. The downward movement of the limiting plate 54 drives the positioning plate 55 to move downward.
[0026] The downward movement of the limiting plate 54 drives the sliding block 63 to move downward. The downward movement of the sliding block 63 drives the spring 64 to move downward. The downward movement of the spring 64 drives the clamping block 65 to slide downward. When the clamping block 65 contacts the rail, it no longer slides downward. When the positioning plate 55 continues to move downward, it pushes the clamping block 65 to slide along the inclined surface to clamp the rail.
[0027] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
