Description
Technical field
The present invention relates to geotechnical engineering field geotechnical centrifuge models, and in particular to a kind of connection of triaxial tester pressure chamber
Device.
Technical background
Existing triaxial tester majority is by bolt by pressure chamber and pressure chamber base interconnection, however in every peace
Installation and dismantling are to require that bolt will be connected to be fastened and loosened except a sample, could complete the experimental implementation of a sample.
Notably, most connections is that 6 bolts in this way are attached, and needs symmetrically to be operated during fastening.By
It needs to make multiple groups sample in triaxial test, if things go on like this greatly wastes experimental period, be unfavorable for the raising of conventional efficient.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of connection of triaxial tester pressure chamber dresses
It sets, the process of bolt fastening can be simplified.
In order to achieve the purpose that foregoing invention, the technical scheme adopted by the invention is as follows：
A kind of attachment device of triaxial tester pressure chamber, including annular chain ring 31, annular chain ring 31 and pressure chamber 1 are fixed
It connects, driven tooth wheel-type screw 33 is connected below annular chain ring 31；Annular chain ring 31 passes through the connection pressure of driving tooth wheel-type screw 32
Power room pedestal 2；The driven tooth wheel-type screw 33 distributes alternately with driving tooth wheel-type screw 32, and is intermeshed, composition
Annulus.
The driving tooth wheel-type screw 32 includes screw rod 30, and one end of screw rod 30 is threadedly coupled with annular chain ring 31, spiral shell
One end of the other end connection hex screw head 34 of bar 30, hex screw head 34 pass through gear 35, are fixedly connected with gear 35, six
The lower end of angle head of screw 34 connects pressure chamber base 2；The driven tooth wheel-type screw 33 includes screw rod 30, one end of screw rod 30
It is threadedly coupled with annular chain ring 31, the other end of screw rod 30 is fixedly connected with gear 35；The driven tooth wheel-type screw 33 with
Driving tooth wheel-type screw 32 distributes alternately, and driven tooth wheel-type screw 33 is mutually nibbled with driving tooth wheel-type screw 32 by gear 35
It closes.
Beneficial effects of the present invention：
The present invention using driving tooth wheel-type screw 32 provide power, driven tooth wheel-type screw 33 not with 2 phase of pressure chamber base
Connection only carries out the transmitting of 32 power of driving tooth wheel-type screw, makes all driving tooth wheel-type screws 32 while rotating, reach
Efficiently, at the same fastening or releasing screw purpose.
Detailed description of the invention
Connection schematic diagram Fig. 1 of the invention.
The structural schematic diagram of Fig. 2 driving tooth wheel-type screw of the present invention and driven tooth wheel-type screw.
Specific embodiment
Present invention is further described in detail with reference to the accompanying drawing.
Shown in referring to Fig.1, a kind of attachment device of triaxial tester pressure chamber, including annular chain ring 31, annular chain ring 31
It is fixedly connected with pressure chamber 1, driven tooth wheel-type screw 33 is connected below annular chain ring 31；Pass through driving tooth below annular chain ring 31
Wheel-type screw 32 connects pressure chamber base 2；The driven tooth wheel-type screw 33 distributes alternately with driving tooth wheel-type screw 32, and
And be intermeshed, form annulus.
Referring to shown in Fig. 2, the driving tooth wheel-type screw 32 includes screw rod 30, one end of screw rod 30 and annular chain ring 31
It is threadedly coupled, one end of the other end connection hex screw head 34 of screw rod 30, hex screw head 34 passes through gear 35, with gear 35
It is fixedly connected, driven tooth wheel-type screw 33 described in the lower end connection pressure chamber base 2 of hex screw head 34 includes screw rod 30, spiral shell
One end of bar 30 is threadedly coupled with annular chain ring 31, and the other end of screw rod 30 is fixedly connected with gear 35；The driven gear
Type screw 33 distributes alternately with driving tooth wheel-type screw 32, and driven tooth wheel-type screw 33 and driving tooth wheel-type screw 32 pass through gear
35 intermeshings.
The working principle of the invention
It is not connected with pressure chamber base 2 in use, gear 35 forms driven tooth wheel-type screw 33 with screw rod 30, for leading
The transmitting of movable tooth wheel-type 32 power of screw makes all driving tooth wheel-type screws 32 while rotating, reaches efficient purpose；It is described
32 bottom end of driving tooth wheel-type screw be threadedly coupled with pressure chamber base 2, realize pressure chamber 1 and pressure chamber base 2 company
It connects, transmitting of the driven tooth wheel-type screw 33 for power between driving tooth wheel-type screw 32, reach while fastening or releasing screw
Purpose.
