Description
Technical field:
The utility model belongs to civil engineering test facility technical field, relate to a kind of spiral punching jack, test and detection for civil engineering anchor pole (rope), make up conventional helical jack and the deficiency of oil pressure punching jack in anchor rod experiment process, can guarantee in process of the test under every one-level load action, along with the increase of anchor pole displacement, it is constant that load keeps, can guarantee again anchor pole (rope) axial tension in test and testing process, not produce moment of flexure.
Background technology:
Along with anchor pole (rope) widespread use in civil engineering, the test of anchor pole (rope) is also essential with detection, especially the creep test of anchor pole (rope), anchor pole is under long-term pulling force effect, and because creep deformation causes the loss of anchor force, its distortion and the relation of time are called the creep of anchor pole, the long-term resistance to plucking ability of anchor pole, that engineering staff extremely pay close attention to, permanent anchor pole particularly, on-the-spot anchor pole creep test is very important for the time effect feature of research anchor rod drawing.Yet, the oil pressure punching jack using in process of the test at present can not provide constant lasting anchor force, lifting screw or leading screw jack can solve the problem of constant lasting anchor force, but are difficult to realize anchor pole (rope) uniaxial force, to test results, can make a big impact.Therefore, design the long-time bearing power that a kind of spiral punching jack pair is determined anchor pole (rope), research anchor pole (rope) drawing time effect is significant, can better be applied to scientific research and engineering practice.
Summary of the invention:
Goal of the invention of the present utility model is to overcome the shortcoming that prior art exists, seek design a kind of spiral punching jack is provided, change gyroscopic movement into straight-line motion, transmit motion and power simultaneously, utilize the swing of manual rocking bar, weight lifting screw sleeve is done straight-line motion and is moved by being fixed on pilot sleeve on body frame, between screw thread, produce self-locking, thereby reach the object of load or unload, the self-locking action between screw thread makes load stable, does not produce load loss.
To achieve these goals, agent structure of the present utility model comprises base, body frame, weight lifting screw sleeve, pilot sleeve, bolt, manual rocking bar, flange and flange blind hole; In the middle of being fixedly shaped with on base, it is the body frame of cavity structure, in the middle cavity of body frame, be shaped with weight lifting screw sleeve, weight lifting screw sleeve is for being provided with externally threaded hollow structure, the embedded middle cavity place that is arranged on base, bottom of weight lifting screw sleeve, the top of weight lifting screw sleeve is stretched out body frame and is connected with flange, and the bilateral symmetry of flange is shaped with flange blind hole; Weight lifting screw sleeve stretches out body frame place and is provided with manual rocking bar; If female orienting sleeve jacket casing is built in weight lifting screw sleeve outside, the negative thread of pilot sleeve inner side and the outside thread of weight lifting screw sleeve are coupled, and the outside of pilot sleeve is fixedly connected with body frame by bolt; During use, rotation manual rocking bar, manually the rotation of rocking bar drives weight lifting railing sleeve and flange to rise, weight lifting screw sleeve is done straight-line motion and is moved by being fixed on pilot sleeve on body frame, between the outside thread of weight lifting screw sleeve and the negative thread of pilot sleeve, produce self-locking, thereby reach the object of load or unload.
The utility model compared with prior art, it is simple in structure, operate nimble, manufacturing process is simple, can carry out better the creep test of anchor pole (rope), for the long-time bearing power of determining anchor pole (rope), research anchor pole (rope) drawing time effect is significant, can better be applied to scientific research and engineering practice.
Accompanying drawing explanation:
Fig. 1 is agent structure principle schematic of the present utility model.
Fig. 2 is the cross section structure principle schematic of the body frame that relates to of the utility model.
Fig. 3 is the cross section structure principle schematic of the base that relates to of the utility model.
The specific embodiment:
Below by embodiment, be also described further by reference to the accompanying drawings.
Embodiment:
The agent structure of the present embodiment comprises base 1, body frame 2, weight lifting screw sleeve 3, pilot sleeve 4, bolt 5, manual rocking bar 6, flange 7 and flange blind hole 8; In the middle of being fixedly shaped with on base 1, it is the body frame 2 of cavity structure, in the middle cavity of body frame 2, be shaped with weight lifting screw sleeve 3, weight lifting screw sleeve 3 is for being provided with externally threaded hollow structure, the embedded middle cavity place that is arranged on base 1, bottom of weight lifting screw sleeve 3, the top of weight lifting screw sleeve 3 is stretched out body frame 2 and is connected with flange 7, and the bilateral symmetry of flange 7 is shaped with flange blind hole 8; Weight lifting screw sleeve 3 stretches out body frame 2 places and is provided with manual rocking bar 6; If female pilot sleeve 4 covers are built in weight lifting screw sleeve 3 outsides, the negative thread of pilot sleeve 4 inner sides and the outside thread of weight lifting screw sleeve 3 are coupled, and the outside of pilot sleeve 4 is fixedly connected with body frame 2 by bolt 5; During use, rotation manual rocking bar 6, manually the rotation of rocking bar 6 drives weight lifting railing sleeve 3 and flange 7 to rise, weight lifting screw sleeve 3 is done straight-line motion and is moved by being fixed on pilot sleeve 4 on body frame 2, between the negative thread of the outside thread of weight lifting screw sleeve 3 and pilot sleeve 4, produce self-locking, thereby reach the object of load or unload.
