Description
Technical field
The utility model belongs to static contact-detection machine, particularly relates to a kind of ground anchorage of static contact-detection machine.
Background technology
Static contact-detection machine is a kind of static cone penetration equipment that foundation soil test is carried out in the fields such as building, water conservancy, electric power that is widely used in, the rotation earth anchor supporting with it is made up of anchor pole and the spiral cutting disc that is arranged at anchor pole one end, and rotation earth anchor drives spiral cutting disc screw in underground certain degree of depth and make earth anchorage by windlass under hydraulic pressure.
Because asphalt surface is made up of roadbed and the pitch top layer of compacting, wherein adopt the pitch table layer thickness of three-layer type top dressing or pitch penetrated technique in 100mm left and right, roadbed thickness is in 200-250mm left and right, and therefore, above-mentioned rotation earth anchor is difficult to screw in asphalt surface.
Summary of the invention
The utility model is in order to solve that the supporting above-mentioned rotation earth anchor of existing and static contact-detection machine is difficult to screw in the technical problem of asphalt surface and ground anchorage that a kind of static contact-detection machine is provided.
The utility model is taked following technical scheme for achieving the above object: a kind of ground anchorage of static contact-detection machine, feature is, described ground anchorage is provided with a lifting rod, its upper end is provided with external screw thread and internal thread, lower end is provided with taper type lifting head, described lifting rod periphery is provided with three symmetrical slips, the lower end of each slips inner side is provided with the inclined-plane engaging with taper type lifting head, the upper end of each slips inner side is provided with circular arc concave station, the circular arc concave station of each slips upper end engages with the ring set that is sleeved on lifting rod, the external screw thread of lifting rod upper end be provided be threaded lift nut and packing ring thereof, described packing ring engages with each slips top, the internal thread of the described lifting rod upper end anchor pole that is threaded, described anchor pole is provided with the nut that is threaded and is anchored on static contact-detection machine chassis or pressing plate.
The utility model can also be taked following technical measures:
Between described ring set and lifting rod, be provided with interval.
Described slips periphery is distributed with radially fin.
Described slips upper end is provided with carries a watt hole.
Described slips length range is 300-500mm, and periphery diameter range when three symmetrical slips sides are bonded with each other is 100-150mm.
The beneficial effects of the utility model and advantage are: the ground anchorage of this static contact-detection machine is arranged to penetrate and claps oil circuit pitch top layer and go deep in the boring of roadbed, lift nut and make lifting rod up by screwing, the taper type lifting head of lifting rod forces swollen outside three symmetrical slips and closely engages with drill hole wall, and its result makes lifting rod and the anchor pole that is threadedly connected to lifting rod be fixed on boring.The effect of the collar is to avoid outer its upper end of slips when swollen to contact with lifting rod.Because the slips length of this earth anchor is suitable with the thickness on asphalt surface roadbed and pitch top layer, and on slips surface, radially fin is set, therefore lifting rod is fixing very reliable.Static contact-detection machine can be anchored in to seat in the plane by multiple anchor pole and clamp nuts thereof that are individually fixed in corresponding lifting rod.The utlity model has simple in structure, easy to use and be applicable to the outstanding advantages of various types of static contact-detection machines and feeler inspection car.
Accompanying drawing explanation
Accompanying drawing 1 is example structure generalized section.
Accompanying drawing 2 is tri-slips sides of Fig. 1 state upward views that are bonded with each other.
Accompanying drawing 3 is the outer swollen front use view of tri-slips of embodiment.
Mark in figure: 1 slips, 1-1 inclined-plane, 1-2 is fin radially, and 1-3 carries a watt hole, 2 lifting rods, 2-1 taper type lifting head, 3 collars, 4 packing rings, 5 lift nut, 6 anchor poles, 7 clamp nuts.
The specific embodiment
Further illustrate the utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in Figure 1, the earth anchor of static contact-detection machine is provided with a lifting rod 2, and its upper end is provided with external screw thread and internal thread, and lower end is provided with taper type lifting head 2-1.
Lifting rod 2 peripheries are provided with three symmetrical slips 1; the lower end of each slips 1 inner side is provided with the inclined-plane 1-1 engaging with taper type lifting head 2-1; the upper end of each slips 1 inner side is provided with circular arc concave station; the circular arc concave station of each slips 1 upper end engages with the ring set 3 that is sleeved on lifting rod 2; between the ring set 3 of embodiment and lifting rod 2, be provided with interval; the effect of ring set 3 be conducive to slips 1 can be outer swollen, and can protect the external screw thread of lifting rod 2.Each slips 1 periphery is distributed with radially fin 1-2, and each slips 1 upper end is provided with respectively carries a watt hole 1-3.
The external screw thread of lifting rod 2 upper ends be provided be threaded lift nut 5 and packing ring 4 thereof, packing ring 4 engages with each slips 1 top.
