Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.

Only those parts relevant to the embodiments of the present utility model are shown for convenience of description.

Referring to fig. 1-3, the sliding seat comprises a base 1, guide components are arranged above the base 1 and on two sides of the base 1, each guide component comprises a middle block 2 rotationally connected with the base 1, a rotating plate 3 is rotationally arranged at the tail end of the middle block 2, rollers 4 are arranged at the positions of the rotating shafts, a limiting block 5 is arranged at the tail end of the rotating plate 3, a first short groove 6 and a second short groove 7 are formed in the limiting block 5, a threaded column 8 penetrates into the first short groove 6 and is fixed to the base 1, a stud 9 penetrates into the second short groove 7 and is fixed to the base 1, a positioning nut 10 is screwed into the top end of the threaded column 8, and a buffer mechanism is arranged on the stud 9.

In the embodiment, the trolley is mounted on the rail 17 through the sliding seat, and when the trolley is in traction, the sliding seat slides on the rail 17 so that the trolley can normally walk on the rail 17.

When the device is specifically applied, the device is arranged on the track according to the requirements, the guide components are respectively positioned above the track and at two sides of the track, and when the travelling crane is towed, the device can slide on the corresponding surface of the track through the guide components, so that the whole machine can normally slide on the track.

Specifically, three gyro wheels in the three direction subassembly are the triangle and arrange, and three gyro wheels are located respectively and paste tightly in track top and track left and right sides for this device is more stable in the slip in-process. When the travelling crane is towed, the three rollers slide along the corresponding surfaces of the rails at the same time, so that the sliding seat is driven to slide, and the travelling crane can be towed to walk normally.

When the sliding seat is installed on a track, firstly, the base is placed on the track according to the requirements, then the rotating plates above the base are sequentially rotated, the rotating plates on the left side and the right side of the base respectively rotate towards three corresponding surfaces of the track, so that the rollers above the base are attached to the upper side surface of the track, the rollers on the left side and the right side of the base are respectively attached to the left side surface and the right side surface of the track, and after the corresponding three rollers are located on the corresponding surfaces of the track, the threaded columns and the studs respectively penetrate into the corresponding first short grooves and the corresponding second short grooves in sequence and are respectively fixed at the corresponding positions of the base. At this time, three gyro wheels are hugged closely on the corresponding face of track respectively, and this device installs on the track this moment, and the design structure that three gyro wheels wherein all are adjustable for this device can adapt to the track of multiple specification size.

And when the threaded column penetrates into the first short groove and is fixed at the corresponding position of the base, finally, the positioning nut is screwed in the top end of the threaded column, and the positioning nut presses the rotating plate. The length of the first short groove is larger than the diameter of the threaded column, so that the threaded column is located in the first short groove and is left with a margin, when the device slides on a track, if the roller shakes on the track, the rotating plate rotates along with the track, and under the limit of the positioning nut, the rotating plate moves a small distance along the length direction of the threaded column at the moment, so that the roller can shake normally.

As shown in fig. 2, the buffer mechanism comprises a spring 11, a gasket 12 and an adjusting nut 13 which are sequentially arranged on the stud 9, and the spring positioned on the stud plays a role of pressing the rotating plate, and also plays a role of buffering if the rotating plate rotates when the roller swings on the track, so that the device is further stable in sliding on the track. The length of the second short groove is larger than the diameter of the stud, the stud is positioned in the second short groove and is transversely left with a margin, the roller is guaranteed to shake normally, and the adjusting screw is matched with the gasket to limit the spring.

As a preferable structure, the base 1 is provided with a avoidance gap 14 in the middle, wherein the upper roller is positioned in the avoidance gap 14. The avoidance notch is mainly used for enabling the roller above to be normally clung to the upper side of the track and enabling the roller above to normally slide on the upper side of the track.

And the device can be taken down from the track after the work is completed. When the device is required to be taken down from the track, all the threaded columns and the studs are required to be unscrewed from the base, the rotating plate can be rotated at the moment, the idler wheels are separated from the corresponding surfaces of the track, and the device can be taken down from the track.

The front end of the base 1 is provided with a groove plate 15, the bottom of the groove plate 15 is provided with a groove 16, and in the structure, the groove plate and the base are fixed into a whole, so that the base is firmer and stronger, and the whole structure is more stable. The groove 16 can avoid the rail, so that the sliding seat can normally slide on the rail.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
