Description
Technical field
The utility model belongs to mine machinery device field, particularly relates to a kind of hydraulic draw column device.
Background technology
Fully-mechanized mining working is to withdraw the pressure due to two lanes and work plane in process large; individual prop often can be caused to bore end phenomenon; due to the restriction in space; generally adopt repeatedly to rock; the space of root at the bottom of individual prop is increased; thus individual prop is extracted, also having is exactly adopt Chain block to draw individual prop, is extracted.But these two kinds of modes are all subject to the restriction in space, but also there is potential safety hazard, easily cause unexpected injury.When withdrawing force piece, due to shield support both sides narrow space, individual prop cannot be rocked on a large scale.
Utility model content
the purpose of this utility model is to provide a kind of hydraulic draw column device, and the utility model structure is simple, reasonable in design, extracts convenient and swift to individual prop, little by space constraint.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of hydraulic draw column device, described device comprises base, and base is installed with hydraulic means, is installed with cambered surface clamp bottom hydraulic means, and hydraulic means top is connected with connecting rod is vertical, and interlinking lever end is provided with anchor ear.
Preferably, described hydraulic means is hydraulic jack.
Preferably, described anchor ear is made up of fixed arch plate and arc of motion plate, and fixed arch plate is fixedly connected with connecting rod, and arc of motion plate and fixed arch plate intrados are oppositely arranged and are bolted.
Preferably, described anchor ear and cambered surface clamp are positioned at the homonymy of hydraulic means.
During work, the utility model is placed on the individual prop side needing to extract, by fixed arch plate and cambered surface clamp laminating individual prop side, then arc of motion plate is connected with fixed arch plate by bolt, make anchor ear only clip live individual prop, then shake the rocking bar of hydraulic jack gently, hydraulic jack drives individual prop to move up by connecting rod and anchor ear, it is extracted from ground.
Compared with prior art, tool has the following advantages the utility model: structure is simple, conveniently moving, compact, space hold is few, reasonable in design, individual prop is extracted convenient and swift, effectively alleviate the labour intensity of workman, add the safety of work progress.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
Fig. 2 is operating diagram of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, a kind of hydraulic draw column device, described device comprises base 1, base 1 is installed with hydraulic jack 2, is installed with cambered surface clamp 3 bottom hydraulic jack 2, hydraulic jack 2 top is connected with connecting rod 4 is vertical, connecting rod 4 end is provided with anchor ear 8, and anchor ear 8 is made up of fixed arch plate 5 and arc of motion plate 6, and fixed arch plate 5 is fixedly connected with connecting rod 4, arc of motion plate 6 is oppositely arranged with fixed arch plate 5 intrados and is connected by bolt 7, and anchor ear 8 and cambered surface clamp 3 are positioned at the homonymy of hydraulic jack 2.
During work, the utility model is placed on individual prop 9 side needing to extract, fixed arch plate 5 and cambered surface clamp 3 to be fitted individual prop 9 side, then arc of motion plate 6 is connected with fixed arch plate 5 by bolt 7, make anchor ear 8 only clip live individual prop 9, and make handle 10 frame on individual prop 9 shaft on anchor ear 8, the then rocking bar of jog hydraulic jack 2, hydraulic jack 2 drives individual prop 9 to move up by connecting rod 4 and anchor ear 8, it is extracted from ground.
