the outer sleeve frame comprises four oil cylinders which are arranged in a square shape, supporting rods 101 are arranged between cylinder bodies 100 of the oil cylinders, and power output ends 102 of the oil cylinders are connected with the inner sleeve frame 100.
In a normal use process, the rotating disc 4 of the suspension arm at the top of the tower body 3 is fixedly connected with the top of the tower body 3.
If the height of the tower body 3 is to be raised, the operation is as follows:
step 1: the suspension arm lifts the tower section, moves the tower section to the position near the open side 202, and weights the suspension arm to enable the gravity center of the tower body 3 to be at the center of the tower body 3;
step 2: loosening the connection between the rotary disc 4 and the top of the tower body 3;
and step 3: the oil cylinder acts, the power output end 102 of the oil cylinder jacks the rotary table 4, so that a space of a tower section is reserved between the rotary table 4 and the tower body 3;
and 4, step 4: the tower section is moved into the reserved space from the open side 202 and is fixedly connected with the tower body 3 and the rotary table 4.
And 5: the connection between the jacket frame and the tower body 3 is released;
step 6: the oil cylinder acts, the power output end 102 of the oil cylinder contracts, and the outer jacket frame is lifted.
And 7: the jacket frame is connected with the tower body 3.
In the whole process, the four oil cylinders act simultaneously, so that the jacking stability is better.
As can be known from the above description, the oil cylinder is in the jacking and stretching process (see steps 3 and 6), the inner sleeve frame 100 rises first, and the outer sleeve frame rises later, in order to improve the operating stability of the inner sleeve member and the outer sleeve frame, improve the life-span of the oil cylinder, improve the jacking and pulling stability of the oil cylinder, be equipped with the first guide piece that sets up with the sliding or roll cooperation mode between tower body 3 and the inner sleeve frame 100, be equipped with the second guide piece 104 that sets up with the sliding or roll cooperation mode between inner sleeve frame 100 and the outer sleeve frame.
