Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to an adjustable crane rail fixing device. Background Art

[0002] Different types of adjustable rail fixtures are suitable for different working conditions and environments. Welded rail clamps and flexible rail clamps are suitable for cranes with medium and heavy duty and light duty, respectively. The LHTZQ series rail fixtures feature adjustable welded clamps suitable for cranes with light and heavy duty. Therefore, selecting the right model is crucial to ensuring equipment stability and safety.

[0003] The current crane track fixing device fixes the track clip plates on both sides of the track steel plate by pressing them. When the track steel plate is replaced with a larger size and thickness, if the gap between the track clip plates and the pressure plates is adjusted to a larger distance, the track clip plates may become loose for a long time. If the track clip plates become loose, the stability and safety of the crane during operation may not be ensured, increasing the risk of derailment or swaying. Utility Model Content

The upper end of the fixing plate 208 is connected to a protruding plate 207 by bolts.

[0022] like Figure 1-3 As shown, the upper end of the protrusion plate 207 is connected to the lower end of the track clip plate 206 by welding, and one end of the track clip plate 206 is connected and fixed to the sliding block 203 by welding. The sliding block 203 is connected to the inside of the pressure plate 201 by welding. A sliding guide groove 202 is opened inside the pressure plate 201. The inside of the sliding block 203 is connected and fixed to the bottom end of the pressure plate 201 by a bolt rod 204. The lower end of the pressure plate 201 is fixedly installed with a buffer pad 103, and the lower end of the buffer pad 103 is fixedly installed on the upper end of the base 102. The lower end of the track clip plate 206 is tightly pressed against the two side ends of the track steel plate 101.

[0023] When the thickness of the lower end of the track steel plate 101 is different, the operator moves the sliding block 203 in the sliding guide groove 202 of the pressure plate 201, and then squeezes one end of the track clip 206 against the upper ends of both sides of the track steel plate 101, and uses the bolt rod 204 to rotate inside the sliding block 203 and connect and fix it inside the lower end of the pressure plate 201. When the internal telescopic spring 213 of the telescopic fixing cylinder 205 moves, the telescopic guide column 210 is further driven to move, and when the track clip 206 is pressed downward on the track steel plate 101, the telescopic spring 213 has a contraction force, and the track clip 206 is further stably pressed on the upper ends of both sides of the track steel plate 101 by the contraction force of the telescopic spring 213, and the operator can According to the actual thickness of the track steel plate 101, the sliding block 203 is moved to perform fine adjustment in the sliding guide groove 202 of the pressure plate 201, so as to achieve precise control of the position of the track clip plate 206.
