Technical field
The present invention relates to a kind of self-locking device, in particular, relate to a kind of for the inspection of foundation pile self-balancing load
Survey the cylinder rod self-locking suit in load box.
Background technology
Owing to national economy is fast-developing, China's infrastructure construction is persistently overheating, high-rise building, especially big public affairs
Road and bridge beam puts into operation in a large number, and the requirement for Pile Bearing Capacity is more and more higher, current Pile
The longest more than 100m, bearing capacity of single pile ultimate value is more than 100000kN.Conventional single-pile static loading test detects
Method obviously can not meet detection demand, and (accumulation load method detection vertical ultimate bearing capacity of single pile is usually no more than
20000kN, anchoring pile Force Method detection vertical ultimate bearing capacity of single pile is usually no more than 50000kN), and foundation pile
Self-balancing approach loading test, owing to not limited by bearing capacity size and site condition, well meets large-tonnage
The requirement of static test, has important practical significance.
In hydraulic system, hydraulic cylinder is main movement transfer member.In many situations, hydraulic cylinder to be locked
It is scheduled on certain position, it is impossible to mobile.But it is due to hydraulic system itself, after hydraulic cylinder rod stretches out, special
Be not with load in the case of, to be fixed on certain position, need constantly pressurization, i.e. need constantly to make
Remain fixing with the energy.Hydraulic cylinder self locking apparatus is created for saving the energy.Traditional hydraulic cylinder self locking apparatus makes
Use spring loaded effect, conic self-locking block is surrounded and is pressed on lever, start the effect of self-locking.But warp
The use of a period of time, the abrasion of generation makes self-locking effect be deteriorated, and locked lever can produce small displacement.
Summary of the invention

It is provided with reinforced steel outside described block set.
Compared with prior art, technical scheme is had the benefit that
(1) present invention is provided with internal with plunger and sealing ring, is externally connected to the cylinder body of input mouth,
Gas or liquid medium is repeatedly injected to cylinder body so that plunger produces vibration and displacement, then pushes away by input mouth
Before dynamic, drift to two side shiftings thus forces semicircle piston ring to tighten to internal diameter, produces power of radially embracing, thus by rear wedge
Capsule at ferrum racks, and discharges high-strength binding liquid；Simultaneously because front drift moves ahead, high-strength viscous by capsule
Knot liquid is extruded and discharges, and semicircle piston ring, cylinder rod, block set are bonded together.
(2) present invention is provided with cushion between block set and semicircle piston ring, when cylinder rod produces axial displacement,
A certain amount of axial displacement can be provided for semicircle piston ring, reduce the relative displacement between cylinder rod and semicircle piston ring,
Be conducive to improving the locking effect to cylinder rod.
(3) in the present invention, semicircle piston ring inner surface is provided with screw thread, increases between semicircle piston ring and cylinder rod
Frictional force, is conducive to the locking to cylinder rod.
(4) in the present invention, the both ends of semicircle piston ring are set to domatic, and outer surface is set to the conical surface, block set
Inner surface is set to domatic with what semicircle piston ring outer surface suited mutually, be more beneficial in extrusion process semicircle piston ring to
Internal diameter tightens, and produces power of radially embracing.
(5) present invention is provided with reinforced steel outside block set, is more beneficial for firmly carrying out pre-to load box
Bury.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, the cylinder rod in foundation pile self-balancing loading detection load box of the present invention is certainly
Lock tube device, including the band being set on cylinder rod 2 block set jaggy 3, is provided with outside described block set 3
Reinforced steel 8, described block set 3 breach both sides inner surface is respectively arranged with capsule groove 15, table in described block set 3
Face is set to domatic with what described semicircle piston ring 1 outer surface suited mutually.Described block set 3 is internal along breach both sides water
Putting down and be symmetrically arranged with two cushions 11, described cushion 11 is respectively arranged with semicircle piston ring 1, described semicircle rises
Enclosing 1 inner surface and be provided with screw thread, the outer surface of described semicircle piston ring 1 is set to the conical surface, described semicircle piston ring 1
Two ends outside be set to domatic, described semicircle piston ring 1 end outer surface is provided with and the gluing of described block set 3
The capsule groove 16 that capsule groove 15 is corresponding, capsule groove 16 and corresponding block set 3 glue of described semicircle piston ring 1
It is respectively arranged with the capsule 4 being packaged with high-strength binding liquid between capsule groove 15, between described capsule 4, is provided with two
Individual front drift 5, is provided with internal with plunger 10 and sealing ring 9, external connection between drift before said two
There is the cylinder body 6 of input mouth 12, with the breach of described block set 3 relative to the contact of two semicircle piston rings 1 of position
It is provided with the capsule 4 being packaged with high-strength binding liquid between end, is provided with between described capsule 4 and described block set 3
Rear drift 7.
The operation principle of the present invention: when hydraulic system starts, by operating cylinder oil nozzle 14 to operating cylinder 13
Fuel feeding, cylinder rod 2 has stretched out under working condition, and produce to prevent station displacement from producing sliding is unfavorable
State is operated.Produced by the device in block set 3 and form self-locking under the effect of radial displacement and bonding force,
Limit the displacement of cylinder rod 2.
First, during the position specified required for cylinder rod 2 work moves to, pressure system is started, by defeated
Enter mouth 11 and repeatedly inject gas or liquid medium to cylinder body 6 so that plunger 10 produces vibration and displacement, promote
Semicircle piston ring 1 and front drift 5 move ahead.Under rear drift 7 and front drift 5 act on, force semicircle piston ring 1
Tighten to internal diameter, produce power of radially embracing.When cylinder rod 2 move ahead generation axial displacement, semicircle piston ring 1 conical surface to
Locking direction is moved, simultaneously because semicircle piston ring 1 radially moves ahead, the high-strength binding liquid in capsule 4 is extruded
Discharge, semicircle piston ring 1, cylinder rod 2, block set 3 are bonded together.Make this device in stress
Under state, do not produce displacement, undertake xial feed power.
