By means of the guiding cooperation of the rollers 31 and the guide grooves 20, the upper supporting frame 1 can be pushed to the upper portion of the lower supporting frame 2 along the inclined rods 21 and the cross rods 22 in sequence, and compared with a traditional crane lifting scheme, the lifting device is more convenient and rapid to install.
For placing the rollers into the guide grooves 20 from the outside, the lower ends of the inclined bars 21 of the lower support frame 2 are extended toward the outside to form lateral extension sections 23, the lateral extension sections 23 are abutted against and fixed on the ground, the lateral extension sections 23 also include guide grooves, the guide grooves of the lateral extension sections 23 are communicated with the guide grooves of the inclined bars 21 of the lower support frame 2, which enables the rollers 31 to move between the inclined bars 21 and the lateral extension sections 23, the outer ends of the lateral extension sections 23 have openings 231 communicated with the guide grooves thereof, and the openings 231 are used for placing the rollers 31 into the guide grooves 20 from the outside, thereby facilitating the combined connection and detachment between the upper support frame 1 and the lower support frame 2.
The bottom inner wall 232 of the guide groove of the transverse extension section 23 is obliquely arranged, so that the roller 31 is convenient to be excessively arranged between the ground and the bottom inner wall 232, and the roller 31 is convenient to be placed into the guide groove of the transverse extension section 23.
The bottom inner wall of the guide groove of the cross bar 22 of the lower support frame 2 is provided with wedge-shaped protrusions 221 which are matched with the rollers 31 to limit unidirectionally, the number of the wedge-shaped protrusions 221 corresponds to that of the rollers 31, and the wedge-shaped protrusions 221 can prevent the upper support frame 1 from being pushed to the installation position to fall back, so that safety can be improved.
It should be noted that: after the upper support frame 1 slides to the corresponding installation position of the upper end of the lower support frame 2 through the rollers, the upper support frame 1 and the lower support frame are fixed through bolts, so that the strength of the whole structure is improved.
As shown in fig. 2, the roller assembly 3 includes a base 32, a connecting shaft 33, and a telescopic swing arm 34, the base 32 is fixed at the lower end of the upper support frame 1, the connecting shaft 33 rotatably passes through the inner side of the base 32, a torsion spring 35 is cooperatively connected between the connecting shaft 33 and the base 32, and two ends of the connecting shaft 33 are connected with a pair of rollers 31 through the telescopic swing arm 34. In this embodiment, two connecting shafts 33 are connected to the base 32, and the two connecting shafts 33 are connected to a pair of rollers 31 through two telescopic swing arms 34, where the two telescopic swing arms 34 are in a relatively inclined posture. Through the connection of connecting axle 33 for flexible swing arm 34 can rotate relative base 32, and the setting of torsional spring 35 can realize the elasticity reset after the swing. Further, the telescopic swing arm 34 can move telescopically within a certain range.
