Description
Technical field
The invention belongs to a kind of prestressd anchor cable regulating devices.
Background technology
In slope tr eatment field, to ensure to face the stabilization of the slope soil body or slope surface building, anchor shaft anchor cable is widely used
Side slope carries out consolidation process, is added to stratum using the anchor cable and corresponding grouting soil for the anchor pole being arranged in stratum
Gu to improve the globality on stratum, stratum deformation is controlled.Prestress anchorage cable is that one end is anchored in rock stratum, then certainly
Tensioning is carried out by end, to banketing or the unstable soil body anchors.Currently, after due to prestress application, with the time
Creep can occur for passage steel strand wires, steel etc., being pressurized for a long time plus the soil body also occurs creep, and steel strand wires will appear apparent prestressing force
Loss, leads to side slope or is reinforced the soil body to be deformed, lose consolidation effect.
In the prior art, the construction of prestressd anchor cable is completed according to disposable apply of design, after loss of prestress,
The difficulty compensated again is larger, and generally only part anchor cable relaxes, and carries out mending tensioning presence using mechanical equipment
The problems such as costly, poor in timeliness.
In the prior art, the design of prestress anchorage cable allows anchor force to be fixed, once anchor cable is by excessive soil
Pressure or landslide power are more than design permissible value, and anchor cable is just it is possible that fracture, may cause slope displacement to be mutated.

The invention will be further described with reference to the accompanying drawings and examples：
Referring to shown in Fig. 1-3：A kind of prestressd anchor cable regulating device comprising fixed seat 1, sliding seat 2, transmission shaft 3, tooth
Wheel 5, anti-rotation jam plate 6 and casing 10.
The fixed seat 1 has transmission shaft interconnecting piece 1-1, sliding slot 1-2 and the edges anchorage cable anchoring section interconnecting piece 1-3, sliding slot 1-2
Horizontally arranged, in the present embodiment, anchorage cable anchoring section interconnecting piece 1-3 is located on the left of sliding slot 1-2, the transmission axis connection
Portion 1-1 is located on the upside of sliding slot 1-2.
The transmission shaft 3 is vertically arranged and is rotatably connected with the transmission shaft interconnecting piece 1-1 in the fixed seat 1.
As a kind of embodiment, referring to Fig. 2, there is transmission shaft interconnecting piece 1-1, the transmission shaft to connect in the fixed seat 1
Socket part 1-1 is equipped with bearing hole 1-11, and the transmission shaft 3 is assemblied in by bearing 9 in the bearing hole 1-11.
As another embodiment, referring to Fig. 3, there is transmission shaft interconnecting piece 1-1, the transmission shaft in the fixed seat 1
Interconnecting piece 1-1 is equipped with screw hole 1-12, has thread segment 3-3, thread segment 3-3 and screw hole 1-12 spiral shells on the transmission shaft 3
Rotation transmission.
Specifically, the sliding slot 1-2 slidable connections in the sliding seat 2 and the fixed seat 1 have rack on the sliding seat 2
4.Each teeth on the rack 4 arranged distribution in the horizontal direction, the gear 5 is coaxially connected with 3 lower end of transmission shaft and the gear 5
Be meshed transmission with the rack 4.
In addition, 3 upper end of transmission shaft is equipped with spline tooth 3-1 and operation handle 3-2, operation handle 3-2 is located at the flower
Above key teeth 3-1.Facilitate the transmission shaft 3 rotation operation.Preferably, wheel disc or cross-bar can be used in operation handle 3-2.
In addition, offer splined hole 6-1 on the anti-rotation jam plate 6 and be set in 3 upper end of transmission shaft, spline tooth 3-1 with
Splined hole 6-1 matches.
The casing 10 is set on the transmission shaft 3 between the fixed seat 1 and spline tooth 3-1；Preferably, should
Preferably, 10 lower end of casing and the transmission shaft interconnecting piece 1-1 of the fixed seat 1 are affixed (affixed using bolt).
The anchorage cable anchoring section interconnecting piece 1-3 of the fixed seat 1 is fixedly connected with anchorage cable anchoring section 7, which, which fixes, connects
Free section of anchor cable 8 is connect, the free section of anchor cable 8 and anchorage cable anchoring section 7 are opposite to each other positioned at the both sides of 2 glide direction of the sliding seat.
Preferably, 6 shape of anti-rotation jam plate is rectangle.The anti-rotation jam plate 6 will not rotate after being put into the soil body, lock shape
State is more preferable.
When implementing installation, the anchorage cable anchoring section interconnecting piece 1-3 of the fixed seat 1 is fixedly connected with anchorage cable anchoring section 7, the sliding seat
2 right ends are fixedly connected with free section of anchor cable 8, then carry out operation of banketing, and fixed seat 1 is embedded in admittedly under the soil body (T) and is located at anchor cable
8 intersection of anchoring section 7 and free section of anchor cable, 3 upper end of the transmission shaft make its spline tooth 3-1 after passing through the casing 10 in soil body T
It is exposed in earth's surface regulating tank T-1 with operation handle 3-2, which is placed in earth's surface regulating tank T-1, the earth's surface tune
Section slot T-1 matches with 6 shape of anti-rotation jam plate, since the anti-rotation jam plate 6 is square and earth's surface regulating tank T-1 is rectangle, because
This anti-rotation jam plate 6 cannot can only rotate up and down in earth's surface regulating tank T-1.
When under normal conditions, the splined hole 6-1 of the anti-rotation jam plate 6 keeps coordinating and being somebody's turn to do with the spline tooth 3-1 on the transmission shaft 3
Anti-rotation jam plate 6, which is fixed, to be buried in earth's surface regulating tank T-1 on blinding body T, since anti-rotation jam plate 6 will not rotate, and the transmission shaft 3 with
6 spline of anti-rotation jam plate is coaxially connected, therefore the transmission shaft 3 is locked by the anti-rotation jam plate 6 and the transmission shaft 3 holding is made not revolve
Turn, it is ensured that prestressd anchor cable is constant.
And when prestressd anchor cable loses or is exceeded, earth's surface regulating tank T-1 is opened, first by 6 uplink one of anti-rotation jam plate
Set a distance (along the directions F in Fig. 4) directly takes out the anti-rotation jam plate 6, makes its splined hole 6-1 and the spline on the transmission shaft 3
Tooth 3-1 is detached from cooperation (reference can be made to Fig. 4), which is unlocked；Then outer power drive operation handle 3-2 and make this again
Transmission shaft 3 rotates, which rotates coaxially with moving gear 5, and the gear 5 engagement drives the rack 4 on sliding seat 2 in fixation
Sliding translation on seat 1, therefore the rack 4 loosens and tightens anchor for driving free section of anchor cable 8 along its axial translation to reach
The effect of rope, and fixed seat 1 is without movement in stress adjustment process.After regulating, which is resetted and is locked
Fixed, i.e. the splined hole 6-1 of the anti-rotation jam plate 6 coordinates with the spline tooth 3-1 on the transmission shaft 3 and lid is buried in the anti-rotation jam plate 6 fixation
In earth's surface regulating tank T-1 on soil body T, therefore the transmission shaft 3 is locked by the anti-rotation jam plate 6 and the transmission shaft 3 is made not rotate.
In addition, when in use, since casing 10 separates safely the transmission shaft 3 with soil body T, soil body T can be kept away and be attached to this
On transmission shaft 3, therefore the transmission shaft 3 can freely and safely rotate while can avoid getting rusty, and can prolong the service life.
Referring to Fig. 5, the cover 1-5 is installed in the fixed seat 1.The cover 1-5 is used for sliding seat 2, gear 5 and rack 4
Protection covers and prevents from contacting with the soil body after its is exposed.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
