Embodiment 1

[0020] Example as figure 1 As shown, it is moved with struts 4 while hydraulic cylinders 3 are positioned on the carrying box 2 . The first group of hydraulic cylinder 3 such as figure 1 The right hydraulic cylinder 3 extends the push rod to lift the carrying box 2. When the carrying box 2 rises to a certain height, the second group of pillars 4 can be moved into the underside of the same group of hydraulic cylinders 3. At this time, the pillars are driven. 4. The moving device 8 moves the column 4 under the hydraulic cylinder 3 of the same group to complete the first step. In the second step, the hydraulic cylinder 3 of the second group extends the push rod, the hydraulic cylinder 3 of the first group contracts, and the carrying box 2 rises to the height of the first group of the second section of the pillar 4, the device 8 for driving the pillar 4 to move again Move the struts 4 of the second section of the first group into the underside of the hydraulic cylinders 3 of the...

Embodiment 2

[0021] Example two is as Figure II Shown: it adopts hydraulic cylinder 3 to move and boss 5 to be fixed. The function of the boss 5 is the same as that of the pillar 4 . When the hydraulic cylinders 3 of the first group move to the bosses 5 of the same group under the push of their driving pistons 9 , their push rods extend, the carrying box 2 rises, and reaches the second set of bosses 5 . The piston 9 of the hydraulic cylinder 3 moves it to the second group of bosses 5, its push rod is extended, the carrying box 2 rises again, and when it reaches the third group of bosses 5, the driving piston of the third group of hydraulic cylinders 3 9. Move it to the third group of bosses 5, its push rod extends, and the carrying box 2 rises again. Afterwards, the sequence of each group repeats the cycle alternately, that is, the rise is completed. When descending, the push rods of each group are retracted, that is, they are descending. When the retraction is completed, the moving pi...

Embodiment 3

[0022] Example 3 is as image 3 As shown, this example adopts the closed-loop unidirectional motion scheme, and the closed-loop includes dual-channel and network closed-loop. On the channel 1 of the closed circuit, there is at least one carrying box 2 , and a driving device 10 is also provided to drive the carrying box 2 to another channel 1 . The driving device can also be arranged on the carrying box 2 to realize the horizontal or oblique movement of the carrying box 2 to another channel 1 . The principle and function of its scheme are the same as those of expressways and double-track railways, and are suitable for rapid and large-volume use.

Abstract

The novel stepped hydraulic lift includes at least two hydraulic cylinders set on the bearing cage and at least two set of supports fitting the hydraulic cylinders, and the supports, guide tracks and power supply wires are set around the passage. It is superior owing to its stepped mode resulting in great elevation height with short stroke hydraulic cylinders and increased bearing capacity, and double channel and one-way network loop motion mode resulting in fast speed and great transport amount. It is suitable especially for high rise building and is safe, simple in structure and reliable, and has many other advantages.

Description

technical field [0001] The present invention relates to a new hydraulic elevator, especially a step-type hydraulic elevator. Background technique [0002] The hydraulic elevators currently in use are mainly lifted by the use of sleeves, which have the advantages of large lifting capacity and so on. However, there are also disadvantages such as low lifting height, about 25 meters, the thrust provided by the primary and final stages of the sleeve is quite different, the installation occupies a large area, one elevator occupies one passage, and the capacity is limited. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a step-type hydraulic elevator that utilizes a short-stroke hydraulic cylinder for long-distance and large-height lifting. Another object is to provide a multi-channel fast and large-capacity stepping hydraulic elevator. [0004] The solution of the present invention is: set the ent...
