Four-linkage lifting omni-directional rotation device

Abstract

The invention provides a four-linkage lifting omni-directional rotation device which comprises a moving beam, a moving oil cylinder, a second flip beam, a flip beam oil cylinder II, a first flip beam,an upper linkage, a front linkage, a rear linkage, a rotation seat, a flip beam oil cylinder I, a lifting oil cylinder, a rotation supporting bearing, a working platform, a locking oil cylinder and alocking press block. The first flip beam is hinged with the upper linkage, one end of the flip beam oil cylinder I is hinged with the first flip beam, the other end of the flip beam oil cylinder I ishinged with the upper linkage, and thus a turnover mechanism is formed. Under the action of the flip beam oil cylinder II and the flip beam oil cylinder I, the turnover mechanism realizes the construction of direction of -90-+90 degrees in the vertical direction. The upper linkage, the front linkage, the rear linkage and the rotation seat are hinged to form a planar four-linkage mechanism. Underthe action of the lifting oil cylinder and the flip beam oil cylinder I, the four-linkage mechanism lifts up and down along a straight line and resists horizontal component, and the stability of the mechanism is improved. By the four-linkage lifting omni-directional rotation device, a drilling machine is easy to move and can meet the construction requirements of different heights and different angles.

Description

technical field [0001] The invention belongs to the technical field of drilling rigs, and in particular relates to a four-link lifting and omnidirectional turning device. Background technique [0002] During the mining process of underground coal mines, due to the complex and changeable coal seam occurrence conditions, major gas accidents often occur. Therefore, in order to prevent local gas safety accidents in coal mines and achieve effective gas extraction and utilization, it is necessary to use drainage drilling rigs for detection before excavation. holes to detect and utilize the gas in the mine to avoid gas explosion accidents. [0003] In order to allow the drilling rig to drill at different angles, a double-slewing bearing lifting mechanism is used in the prior art, please refer to the structural diagram figure 1 , figure 2 , image 3 , Figure 4 , the rotary mechanism of the drilling rig in the prior art includes: the first rotary mechanism 101, the second rotar...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure is too high, and the underground transportation and construction are difficult

[0005] 2. The anti-reaction performance of the drill pipe is poor, the rotary mechanism is seriously damaged, and the maintenance cost is high

[0006] 3. The stability of the mechanism is poor, and the construction instability causes the drilling to deviate, and the deep hole construction cannot be carried out.
