The weight of block 5 and catch 7；The top of fixed support 1 be provided with two pulleys 9 and with the matching used traction fiber of pulley 9 10, it is sliding
Wheel 9 is located at the top of the first guide rail 2 and the second guide rail 3 respectively, and traction fiber 10 is steel wire rope, and traction fiber 10 passes through two pulleys 9,
One end of traction fiber 10 connects the first sliding block 4, and the other end connects the second sliding block 5；Set respectively on first guide rail 2 and the second guide rail 3
It is equipped with chute 13, the first sliding block 4 and the second sliding block 5 and is respectively arranged with the anti-rotation projection 14 matched with chute 13, anti-rotation
Dynamic projection 14 is integrally formed with the first sliding block 4 or the second sliding block 5, and the anti-rotation projection 14 that chute 13 matches with chute 13 is set
Putting can prevent the first sliding block 4 and the second sliding block 5 from being rotated relative to the first guide rail 2 and the second guide rail 3, it is to avoid be led because rotating drive
Draw silk 10 and cause the movement of the second sliding block 5；Fig. 2 is the transverse sectional view of the first guide rail 2 and the first sliding block 4, and second leads
The transverse sectional view of the sliding block 5 of rail 3 and second is not provided, but the second guide rail 3 and chute 13 and and chute on the second sliding block 5
Chute 13 shown in position, structure and the shape and Fig. 2 of the 13 anti-rotation projections 14 matched and with chute 13 match it is anti-
Rotate position of the projection 14 on the first guide rail 2 and the first sliding block 4, structure and shape consistent；The bottom of fixed support 1 is set
There is clip 12 to be fixed on fixed support 1 on the bar-like support frame outside vertical displacement detection means.
The guide rail 2 of fixed support 1 and first, the second guide rail 3 and pulley 9 can be integrally formed or by welding,
The mode such as grafting or threaded connection interfixes.Between first sliding block 4 and drawing piece 6 and can between the second sliding block 5 and catch 7
To be to be integrally formed, it can also be interfixed by modes such as welding, grafting or threaded connections.Fixed support 1 in the present embodiment
Connected mode with the first guide rail 2, the second guide rail 3 and pulley 9 is welding, between the first sliding block 4 and drawing piece 6 and second
Connected mode between sliding block 5 and catch 7 is similarly welding.Clip 12 is by being fixedly welded on fixed support 1 in the present embodiment
Bottom.Certain clip 12 can also be connected by modes such as grafting or threaded connections with fixed support 1.
Fig. 3 is refer to, in a particular embodiment, support frame 15 is external structure, non-component of the present utility model.Hundred
Divide table 11 to be fixed by support frame 15, in addition to being contacted with catch 7, do not filled with vertical displacement detection disclosed in the utility model
Other parts in putting are in contact, to avoid interfering with each other for dial gauge 11 and other parts.Fixed support 1 is installed, admittedly
It is scheduled on external structure（Such as fixed platform or bar-like support frame）On（Do not provided in Fig. 3）, fixed support 1 can be mounted directly,
It is fixed in external structure, can also be installed, be fixed on bar-like support frame by clip 12.
In testing, we, which generally require to treat, detects that multiple positions of article are tested.When needing to treat detectable substance
When multiple positions of product are tested, we only need to use multiple vertical displacement detection means.It is worth noting that, position
The contact position for moving detector and catch 7 is not fixed, and displacement detector can be contacted with the top surface of catch 7 can also be with catch
7 bottom surface contact, and do not influenceed by the direction of displacement of catch 7, but need to carry out zeroing benchmark to displacement detector.
Operation principle of the present utility model is：Fixed support 1 is fixed in external structure, and keeps first to lead as far as possible
The guide rail 3 of rail 2 and second is configured with traction fiber 10, traction fiber 10 to reduce perpendicular to ground on the error that friction etc. is brought, pulley 9
Two ends connect the first sliding block 4 and the second sliding block 5 respectively, because the weight of the first sliding block 4 and drawing piece 6 is more than the He of the second sliding block 5
The weight of catch 7, therefore the first sliding block 4 and drawing piece 6 can give the second sliding block 5 one upward pulling force, but the second sliding block 5 is logical
Cross displacement silk 8 and be connected to article to be detected, therefore displacement silk 8 can give the second sliding block 5 one downward pulling force so that the second sliding block
5 temporarily in static state, and when treating detection article and being tested, article to be detected is in internal force or external force effect
The lower displacement for occurring vertical direction, drives displacement 8 displacements of silk, vertical displacement occurs therewith for the second sliding block 5, positioned at the second sliding block 5
On catch 7 vertical displacement can also occur therewith, now by above catch 7（Or below）Displacement detector（This
It is dial gauge 11 in embodiment）To measure the vertical displacement amount of catch 7, the vertical displacement amount of article to be detected is then detected.
Implementation of the present utility model is further illustrated by taking self-balancing approach detection bearing capacity of single pile as an example, is specially：
Fixed support 1 is fixed on the external structure beyond foundation pile（Such as fixed platform or bar-like support frame）On, and keep as far as possible
First guide rail 2 and the second guide rail 3 are configured with traction piece 10 to reduce perpendicular to ground on the error that friction etc. is brought, pulley 9, lead
Draw the two ends of part 10 and connect the first sliding block 4 and the second sliding block 5 respectively, slided because the weight of the first sliding block 4 and drawing piece 6 is more than second
The weight of block 5 and catch 7, therefore the first sliding block 4 and drawing piece 6 can give the second sliding block 5 one upward pulling force, but second slides
Block 5 is connected to the top of load box by displacement silk 8（Or bottom）, therefore displacement silk 8 can give the second sliding block 5 one downward drawings
Power so that the second sliding block 5 is temporarily in a static state, when carrying out loading test to load box, due to stress, load
Case can be subjected to displacement（Deformation）, will be shifted up at the top of load box, the bottom of load box can be moved down, therefore drive displacement silk 8 to move up
（Displacement silk 8 is to move down when connecting the bottom of load box）, the second sliding block 5 moves up therewith（When displacement silk 8 connects the bottom of load box
To move down）, the catch 7 on the second sliding block 5 can also move up therewith（Displacement silk 8 is to move down when connecting the bottom of load box）,
The vertical displacement amount of catch 7 is measured by the dial gauge 11 above catch 7, can now obtain catch 7 test when
Vertical displacement amount, you can obtain the vertical displacement amount of load box., can when needing further to obtain the performance parameter of load box
By the displacement and other specification of catch 7（Required parameter during bearing capacity of single pile is tested conventionally by load box, is existing skill
Art）Combine, it is possible to complete the test to bearing capacity of single pile.In the test of load box, it may be desired to load
Multiple positions of case are tested, when needing multiple positions to load box to test, and we are only needed to independently, while making
With multiple vertical displacement detection means.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art is in the technical scope that the utility model is disclosed, the change that can be readily occurred in
Change or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with described
Scope of the claims is defined.
