Detailed Description

The following description of the preferred embodiments of the present invention will be provided with reference to the accompanying drawings, so that the advantages and features of the present invention can be easily understood by those skilled in the art, and the scope of the present invention can be clearly and clearly defined.

Fig. 1-7 show a cross beam lifting device for a gantry machine according to the present invention, which is disposed on the base of the gantry machine and below the cross beam 9 to lift the cross beam to a certain height. The gantry machine of the present embodiment is a conventional component in the prior art. The device comprises a base 1, a movable seat 2 which is arranged on the base 1 and moves up and down relative to the base 1, and a lifting mechanism 8 which is used for driving the movable seat 2 to move up and down. Wherein, the main bodies of the base 1 and the movable seat 2 are formed by welding square pipes. The base 1 comprises four vertically arranged first square tubes 11. The movable seat 2 includes four second square tubes 21 arranged corresponding to the first square tubes 11. The first square pipe 11 and the second square pipe 21 are both hollow. The second square tube 21 is inserted into the first square tube 11 and is connected with the first square tube 11 in a sliding fit manner. Through the above structural design, the second square pipe 21 can move up and down in the first square pipe 11, so that the movable seat 2 can move up and down relative to the base 1. The lifting mechanism 8 is fixed on the base 1, and the driving end of the lifting mechanism is connected with the movable seat 2 so as to drive the movable seat 2 to move up and down. The lifting mechanism 8 is preferably a jack. The jack of this embodiment is conventional in the art.

The apparatus of this embodiment comprises a roller 3 and an adjustment assembly. A plurality of groups of rollers 3 are arranged on the movable seat 2 at intervals along the left-right direction, and two ends of each roller 3 are rotatably connected with the movable seat 2 through bearings, so that the rollers can rotate around the central axes of the rollers. When the movable seat 2 is lifted upwards, the beam 9 is abutted with the peripheral surface of the roller 3.

The adjusting component is arranged at the outer sides of the two ends of the roller 3 and comprises a plug connector 4 and a mandril 5 in threaded connection with the plug connector 4. The number of the adjusting components is determined according to actual requirements. The plug connector 4 is in up-and-down plug fit with the movable seat 2 and has a plug-in position. In the plugged position, one end of the ram 5 is arranged facing the drum 3. By rotating the jack 5 forward and backward, the relative positions of the jack 5 and the plug 4 can be adjusted so that the jack 5 can move in a direction toward or away from the roller 3. The connector 4 and the movable seat 2 have a matching structure for limiting the rotation of the connector 4 at the plugging position. By the restriction of the fitting structure, the plug 4 is prevented from rotating when the jack 5 is rotated forward or backward. The fitting structure includes a jack 22 mounted on the movable base 2 and a plug 41 mounted on the plug 4. The insertion hole 22 is a polygonal hole. The inserting rod 41 is a polygonal cylinder corresponding to the polygonal hole. The socket 22 is preferably a regular hexagonal hole, and the plunger 41 is preferably a regular hexagonal cylinder.
