Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.
Referring to the attached drawings 1 to 4, in the embodiment, a tower crane body jacking frame is suitable for the field of existing tower cranes, and is particularly used in cooperation with a tower crane standard section 2 of a tower crane and a jacking outer sleeve frame 3 sleeved on the periphery of the tower crane standard section 2.
The jacking frame of the embodiment comprises a jacking frame 1, wherein the jacking frame 1 is formed by welding four side cross beams 11. The two ends of the top surface of each side cross beam 11 are respectively provided with an upper guide wheel 21, the two ends of the bottom surface of each side cross beam 11 are respectively provided with a lower guide wheel 22, the axes of the upper guide wheels 21 between any two side cross beams 11 are arranged in a mutually perpendicular mode, and the axes of the lower guide wheels 22 between any two side cross beams 11 are arranged in a mutually perpendicular mode. The upper guide wheels 21 are vertically aligned with the lower guide wheels 22 in a one-to-one correspondence manner.
From this, four corner positions at jacking frame 1 have formed and have had guide pulley 21 and two lower guide pulley 22 on two, so that the jacking frame cover is established when tower crane standard festival 2 is peripheral, guide pulley 21 corresponds the both sides angle lateral wall inconsistent cooperation with tower crane standard festival 2 in jacking frame 1's top through two of same corner position, and guide pulley 22 corresponds the both sides angle lateral wall inconsistent cooperation with tower crane standard festival 2 in jacking frame 1's below through two of same mark position of gluing, thereby play the function of direction and location, can effectively avoid the problem that takes place the aversion during the jacking operation.
Further, each of the upper guide wheel 21 or the lower guide wheel 22 is provided with a guide wheel bracket connected to the side cross member 11.
Referring to fig. 5 and 6, in the embodiment, two side beams 11 located at opposite sides are respectively provided with an oil cylinder fixing 13 fastener and two supporting climbing claws 14, the oil cylinder fixing 13 fastener is fixed at the top of the side beam 11 by welding, the oil cylinder fixing 13 fastener is used for connecting the end of a telescopic oil cylinder 31 preset on the jacking outer jacket frame 3, and thus the oil cylinder fixing 13 fastener on the two side beams 11 is connected with the two telescopic oil cylinders 31 on the jacking outer jacket frame 3, so that the connection and matching of the jacking frame 1 and the jacking outer jacket frame 3 are realized. Each supporting climbing claw 14 is provided with a climbing claw bracket connected with the side beam 11, wherein the supporting climbing claws 14 are hinged to the climbing claw brackets through bolts, so that the supporting climbing claws 14 can swing up and down around the bolts. The claw 14 is climbed in the support is used for contradicting the cooperation with tower crane standard festival 2, specifically, establishes when tower crane standard festival 2 is peripheral when jacking frame 1 cover, climbs claw 14 with each support by swing to horizontality under original vertical state to take on the crossbeam of tower crane standard festival 2, thereby play the support to jacking frame 1, can climb claw 14 swing with the restriction support with the bolt locking this moment. On the contrary, the supporting climbing claw 14 can be swung up to the horizontal state by loosening the bolt, so that the supporting jacking frame 1 can be released, and the jacking frame 1 can move freely.
Furthermore, the two supporting climbing claws 14 positioned on the cross beams 11 on the same side are positioned on two sides of the oil cylinder fixing 13 buckle, so that the four supporting climbing claws 14 on the cross beams 11 on the two sides are utilized to support, and the supporting performance and the stability are better.
During jacking operation, the supporting climbing claws 14 of the jacking frame 1 are in lap joint with the cross beam of the tower crane standard knot 2 in advance, and support for the jacking frame 1 and the jacking outer sleeve frame 3 is achieved. Then, the piston rods of the two telescopic cylinders 31 of the jacking outer jacket frame 3 synchronously extend downwards to apply pressure to the jacking frame 1, so that the jacking outer jacket frame 3 ascends by utilizing the generated reverse acting force, and the jacking operation is completed.
The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents of the embodiments of the invention without departing from the scope of the invention. Therefore, the content of the technical scheme of the utility model, according to the equivalent change made by the idea of the utility model, should be covered in the protection scope of the utility model.
