Description
Technical field
The present invention relates to a kind of jack, refer more particularly to a kind of jack that is applicable to the axis force of anchor meter.
Background technology
The axis force of anchor meter is a kind of a kind of testing tool of measuring anchor-holding force of anchor bolt, and it has significant role to research, the inspection of engineering quality of anchor bolt support engineering and various anchor poles.The important component part of axis force of anchor meter comprises jack, the jack load capacity that present axis force of anchor meter is used is limited, the movable sensitieness of piston is relatively poor, and itself does not have pressure display table, outer compression indicator dynamometry that connects all, because external compression indicator dynamometry position oil circuit is longer, numerical value is not accurate enough.
Summary of the invention
The technical problem to be solved in the present invention provides the jack that a kind of axis force of anchor meter is used.
In order to solve the problems of the technologies described above, the invention provides the jack that a kind of axis force of anchor meter is used, comprise inner cylinder body and base, described inner cylinder body is captiveed joint with base, be provided with pull bar in described inner cylinder body and the base, described pull bar runs through whole inner cylinder body and base, inner cylinder body is with outer cylinder body outward, described outer cylinder body is provided with gland, described gland, inner cylinder body and outer cylinder body surround the sealing chamber, the indoor piston that is provided with of described enclosed cavity, described inner cylinder body is provided with oil connector and oil circuit, and described oil connector is provided with compression indicator.
As a further improvement on the present invention, the inner periphery of described piston and excircle are respectively equipped with rubber ring.
As a further improvement on the present invention, described piston is provided with at least five group stage clips.
As a further improvement on the present invention, be provided with outer connected nut in the described base, described outer connected nut is captiveed joint with the pull bar afterbody.
As a further improvement on the present invention, described outer cylinder body is provided with gland nut.
Adopt said structure, its beneficial effect is: described inner cylinder body is provided with oil connector and oil circuit, described oil connector is provided with compression indicator, external oil pipe links to each other with oil connector, external oil pump is by oil transportation in the oil circuit phase jack, be subjected to the pressure of piston, can produce spill pressure in the oil circuit, compression indicator induces spill pressure numerical value and can intuitively show; Inner periphery and the excircle of described piston are respectively equipped with rubber ring, can guarantee to seal chamber and keep better leak tightness, reduce the friction of piston and chamber inner wall simultaneously; Described piston is provided with at least five group stage clips, promotes the jack load capacity; Be provided with outer connected nut in the described base, it is more firm that pull bar is captiveed joint with the anchor pole in the drive.
Description of drawings
Fig. 1 is the structural representation of drainage tube of the present invention.
Among the figure: the 1-inner cylinder body, the 2-base, the 3-pull bar, the 4-outer cylinder body, the 5-gland, 6-seals chamber, 7-piston, 8-oil connector, 9-oil circuit, 10-compression indicator, 11-rubber ring, 12-stage clip, the outer connected nut of 13-, 14-gland nut.
The specific embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the jack that a kind of axis force of anchor meter is used, comprise inner cylinder body 1 and base 2, described inner cylinder body 1 is captiveed joint with base 2, be provided with pull bar 3 in described inner cylinder body 1 and the base 2, described pull bar 3 runs through whole inner cylinder body 1 and base 2, the inner cylinder body 1 outer outer cylinder body 4 that is with, described outer cylinder body 4 is provided with gland 5, described gland 5, inner cylinder body 1 and outer cylinder body 4 surround sealing chamber 6, are provided with piston 7 in the described sealing chamber 6, and described inner cylinder body 1 is provided with oil connector 8 and oil circuit 9, described oil connector 8 is provided with compression indicator 10, the inner periphery of described piston 7 and excircle are respectively equipped with rubber ring 11, and described piston 7 is provided with at least five group stage clips 12, are provided with outer connected nut 13 in the described base 2, described outer connected nut 13 is captiveed joint with pull bar 3 afterbodys, and described outer cylinder body 4 is provided with gland nut 14.
Use before this jack, should seal the air that chamber 6 inside mix with getting rid of by first base measuring pressure table 10, method is that pull bar 3 is pulled to range, compression indicator 10 shows the range value of regulation, pull bar 3 is kept in the center, compression indicator 10 is shown as zero, so repeat several times, if compression indicator 10 numerical value bias frees can use, earlier external oil pump and oil pipe are joined with oil connector 8 during use and fixed, base 2 is installed and drive in, with the anchor pole in outer connected nut 13 steady braces 3 and the drive, the operation oil pump, by in the oil circuit 9 input jacks, machinery oil promotes piston 7 and advances with machinery oil, stage clip 12 produces bounce and stops piston 7 to advance, produce spill pressure in the oil circuit 9 thus, intuitively be presented on the dial plate behind compression indicator 10 these pressure of induction, for reading.
The jack that the similar designed axis force of anchor meter of technical characterictic of any employing and the present invention is used will fall within protection scope of the present invention.
