Embodiment Construction

[0013] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0014] see figure 1 , a crane, comprising an outer cylinder 1, an inner cylinder 2 and a cantilever 9; the inner cylinder 2 is sleeved in the outer cylinder 1, a cantilever 9 is installed on the top of the inner cylinder 2, and a rubber gasket 3 is set on the inner cylinder 2, The rubber gasket 3 is located between the inner cylinder 2 and the outer cylinder 1; when in use, the rubber gasket 3 acts as a seal to prevent dust and the like from falling into the gap, and can also prevent the inner cylinder 2 and the outer cylinder 1 from rubbing against each other to cause abrasion. Function: a hydraulic drive system 4 is installed at the bottom of the outer cylinder 1, and a shock absorber 7 is provided under the hydraulic drive system 4, and the bottom end of the inner cylinder 2 is always socketed inside the outer cylinder 1, and the bottom end of t...

Abstract

The invention discloses a crane, comprising an outer barrel, an inner barrel and a cantilever; the inner barrel is sleeved in the outer barrel, the cantilever is arranged at the top end of the inner barrel, a rubber washer is sleeved on the inner barrel; a hydraulic driving system is arranged at the bottom of the outer barrel, a shock pad is arranged below the hydraulic driving system; a lubricating oil storage tank is connected to the top end of the outer barrel; a fixed base is arranged at the bottom of the shock pad and is fixedly connected with the ground by bolts; a triangular reinforcing rib is arranged above the inner barrel, the upper parts of the inner barrel and the triangular reinforcing rib are connected with the cantilever; the cantilever comprises a stop pin, a telescopic boom, a wire cable, a sliding mechanism, a telescopic motor, a reset spring and a weight box; and the stop pin is arranged at the right front end of the telescopic boom, the left end of the telescopic boom is connected to the inside of the cantilever in a sliding way, and the left end of the cantilever is provided with the weight box. The crane can prevent dust and abrasion, is good in sealing and lubricating effect, conforms to engineering mechanics, and can save energy.

Description

technical field [0001] The invention relates to a crane, in particular to a crane. Background technique [0002] Cantilever crane is a small and medium-sized lifting equipment developed in recent years. It has a unique structure, is safe and reliable, and has the characteristics of high efficiency, energy saving, time-saving, labor-saving, and flexibility. Other conventional lifting equipment shows its superiority; cantilever cranes are widely used in different places in various industries, and their working strength is light. The crane is composed of a column, a slewing arm slewing drive device and an electric hoist. Large lifting capacity, economical and durable. [0003] However, in the prior art, the height of the column of the cantilever crane is generally small and adjustable, and the usability is small and flexible enough to meet the work requirements of special occasions. Contents of the invention [0004] The object of the present invention is to provide a crane...
