Description

Technical Field

[0001] The utility model relates to the technical field of rail clamps, in particular to a guide and limit device for rail clamps. Background Art

[0002] The track clamp is a crane safety device that prevents outdoor cranes from sliding along the track under strong winds. It usually clamps the two sides of the track head to prevent sliding. The track clamp is connected to the locomotive through the hole at the rear end of the clamp shaft. When the locomotive is moving, it drags (pushes) the track clamp to move synchronously. The guide wheel can roll along the serpentine track under the weight pressure of the track clamp, and drive the track clamp as a whole to float along the track surface on the fixed axis through the guide wheel bracket and the guide clamp shaft.

[0003] According to the application number 202320098099.8, a track clamp locking device is disclosed. Through the setting of the locking assembly, the locking ear and the clamp can be locked, further improving the clamping force of the clamp on the track, avoiding the phenomenon that the steel frame still slides on the track when encountering strong winds due to loose fixation, and can effectively prevent the clamp from loosening after clamping, thereby reducing the risk of the device sliding or falling off the track, and facilitating use.

[0004] The following problems still exist in actual use:

[0005] The existing track clamp prevents sliding by clamping the two sides of the track head with a tooth plate. When the track clamp is running, the tooth plate and the track wall are relatively small. When the joint of the two guide rails is offset, the tooth plate and the offset joint interfere with each other during the movement of the track clamp, resulting in a fault and shutdown. At the same time, it is not appropriate to design a larger offset between the tooth plate and the track wall. Therefore, a guide limit device for the track clamp is proposed to address the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a guide and limit device for a rail clamp, which has the advantage of being equipped with a guide and limit device. Through the ball head design of the guide device and in combination with a disc spring, the overall axis of the rail clamp trolley part can be offset to miss the joint when encountering a staggered joint, thereby solving the problems raised in the background technology.

[0007] The utility model provides the following technical solution: a guide and limit device for a rail clamp, comprising a guide rail, a trolley assembly is slidably connected to the surface of the guide rail, brake arms are rotatably connected to both sides of the trolley assembly, a tooth plate is fixedly connected to the bottom end of the brake arm, and guide components are arranged at both ends of the tooth plate;

[0008] The guide assembly includes a guide bracket, a nut, a disc spring, a top block and a mounting hole. The guide bracket is in the shape of an inverted "L" shape and is arranged at the four corners of the bottom of the trolley assembly. A nut is arranged inside the guide bracket. The nut is arranged at an end close to the guide rail with a disc spring. The disc spring is arranged at an end close to the guide rail with a top block. The upper surface of the guide bracket is arranged with a mounting hole.

[0026] By providing a guide component 5, when the trolley assembly 2 is in contact with the misaligned part, the overall axis of the trolley assembly 2 is offset from the missed joint, thereby playing a role in correcting the deviation. When the trolley assembly 2 passes through the staggered joint of the two guide rails 1, the top block 504 first contacts the misaligned part. Since the protruding part of the top block 504 is a sphere, the disc spring 503 can make the top block 504 move along with the misaligned part to correct the position of the rail clamp.

[0027] See also Figures 1 to 4 The guide bracket 501 is fixedly connected to the bottom of the trolley assembly 2 by bolts, the nut 502 is connected to the internal thread of the guide bracket 501, one end of the disc spring 503 is fixedly connected to the nut 502, the top block 504 is fixedly connected to the other end of the disc spring 503, and the mounting hole 505 is opened on the upper surface of the guide bracket 501.

The guide bracket 501 is fixedly connected to the bottom of the trolley assembly 2 by mounting bolts in the mounting hole 505;

[0028] The guide assembly 5 is fixed by inserting bolts into the mounting hole 505 and the trolley assembly 2 and tightening them. The horizontal position of the guide bracket 501 can be moved by loosening the bolts, and the distance between the top block 504 and the guide rail 1 can be adjusted to increase flexibility.

[0029] See also Figures 5 and 6 The top of the brake arm 3 is fixedly connected with a mounting plate 6, a hydraulic cylinder assembly 7 is installed between the two mounting plates 6, spring assemblies 8 are arranged on both sides of the hydraulic cylinder assembly 7, both ends of the spring assembly 8 are fixedly connected with the inner wall of the mounting plate 6, and horizontal sliders 9 are installed at both ends of the trolley assembly 2;

[0030] When the track needs to be clamped, the mounting plate 6 is pushed by starting the hydraulic cylinder assembly 7 to move, which can drive the two brake arms 3 to rotate on the trolley assembly 2, and at the same time drive the tooth plate 4 to move toward the guide rail 1, so that the two tooth plates 4 are close to each other and fit with both sides of the track to clamp the track and achieve a wind-resistant effect.

[0031] In the utility model, the working principle of the device is as follows:

[0032] First, install the guide component 5 to the bottom of the trolley assembly 2, insert the bolts into the mounting holes 505 and the trolley assembly 2, and fix the guide bracket 501 after tightening. When the track needs to be clamped, the hydraulic cylinder assembly 7 is started to push the mounting plate 6 to move, which can drive the two brake arms 3 to rotate on the trolley assembly 2, and at the same time drive the tooth plate 4 to move toward the guide rail 1, so that the two tooth plates 4 are close to each other and fit with both sides of the track to clamp the track to achieve wind resistance. Otherwise, the hydraulic cylinder assembly 7 is closed and the The spring assembly 8 can drive the tooth plate 4 to reset and contact the trolley assembly 2 to limit the trolley assembly 2, so that the trolley assembly 2 can continue to slide on the guide rail 1. When the joint between the two guide rails 1 is misaligned, the trolley assembly 2 will first contact the misaligned part with the top block 504 during the passing process. Since the protruding part of the top block 504 is a sphere, the disc spring 503 can make the top block 504 move with the misaligned part, so that when it contacts the misaligned part, the overall axis of the trolley assembly 2 will be offset and miss the joint, thereby playing a role in correcting the deviation.
