Abstract
The utility model relates to a probe rod clamping device, which is used for hand-clip-probe-rod type static-force-contact-detection machine. At least two sets of clamping blocks with slips are arranged on and connected with both sides of the clip rod body via screw bolts and nuts. The center distances from the probe rod fastening hole of the clip rod body to the center of the two screw bolts are unequal and the ratio is between 1 to 1.5 and 1 to 2. The clamping force of the utility model is 3 times as great as the clamping force of the forcing-screw clamping device and 2.5 times as great as the clamping force of the single-clip clamping device. The clamping ability is enhanced and the detection work of the deep hole of the tall building foundation can be conducted without adding or changing any other accessories. The utility model has the advantages of convenient operation, labor saving and long service life.
Description
The utility model relates to a kind of feeler lever clamping device that is used for hand card probe rod type static sounding machine, multiple-card clamping device.
The feeler lever clamping device of existing hand cassette static sounding machine mostly is the jackscrew formula, and the patent No. 92208516.1 " a kind of clamped-in style chuck " provides a kind of single deck tape-recorder formula clamping device, slips is arranged in the clamp, and clamp transmits nut torque and drives the slips chucking or throw off feeler lever.Though clamping force is bigger than jackscrew formula clamping device, long service life, but when static cone penetration resistance or pulling force are big can not clamp the feeler lever inspecting hole exploration of highrise building ground (particularly to) effectively and cause slide bar, exploration be can't continue, feeler lever and slips damaged simultaneously again.
It is a kind of easy to operate that the purpose of this utility model is to provide, and clamping force is especially big, the multiple-card clamping device of long service life.
The utility model is achieved in that in kelly body both sides, the clamp that has slips connects into integral body by bolt, nut and kelly body, have at least the Second Mate to be connected with the kelly body by bolt, nut with the clamp of slips, the feeler lever holes for clamping center of kelly body is respectively 1:1.5～2 to the center to center distance at two bolt centers.
Fig. 1. structural representation of the present utility model.
Fig. 2. the vertical view of Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Kelly body (1) has feeler lever holes for clamping, the reeded strip in two sides for the centre, and two ends, the left and right sides are the middle cylinder that through hole is arranged.
Clamp (2) has a through hole on being, the strip of a band waist shape step through-hole, and slips (3) is fitted with screw and is fixed on clamp (2) medial surface, and slips (3) flank of tooth symmetry is provided with in opposite directions.
The Second Mate is arranged by the upper and lower position with the clamp (2) of slips (3), be close to four bolts (4), nut (5) and be fixed on kelly body (1) the grooves on two sides plane, and make the center to center distance of feeler lever holes for clamping center to two bolt centers, by last row 1:2, arranging the relation of 2:1 or upper and lower row down and all be 1:2 or upper and lower row and all be the relation of 2:1 fixes, again the left and right two ends of kelly body (1) are enclosed within respectively on the piston rod of two oil cylinders of quiet spy machine, and just be assembled into nut and the quiet spy machine two clips clamping device that fuses, just can use.
During use, turn four nuts (5) earlier, slips (3) is adjusted to certain aperture, and then turn two long-armed nuts (5) and slips (3) is tightened or unclamp feeler lever, chucking feeler lever when tightening by the upper and lower motion of oil cylinder, drives clamping device upper and lower motion simultaneously.Then break away from feeler lever when unclamping, make slips (3) and feeler lever can do relative motion and by artificial wrench operated control.
When penetrating power or pulling force hour, can be only with single pair of clamping device, when injection or pulling force are big, just use above-mentioned Second Mate or Third Mate or overpay clamping device and clamp simultaneously, reach and increase the exploration work that chuck(ing) capacity is finished highrise building ground inspecting hole, need not change and increase other servicing unit, freely select to use by the operator.
The utility model is compared with prior art: because of Second Mate's clamp is arranged, slips and feeler lever contact surface are big, make feeler lever stressed evenly.Therefore under the active force of the same terms, its clamping force is 3 times of former jackscrew formula clamping device, is 2.5 times of single deck tape-recorder formula clamping device, is specially adapted to the static sounding operation of deep hole.
During use, as long as turn the nut of long arm end, it is just more laborsaving than originally to reach identical clamping force, has alleviated labour intensity, can prolong the application life of clamping device simultaneously again.Easy to operate, flexible, can assemble the clamp of varying number according to different needs, highly versatile, the scope of application is wide.
Claims (2)
1, a kind of multiple-card clamping device, in kelly body (1) both sides, the clamp (2) that has slips (3) connects into integral body by bolt (4), nut (5) with kelly body (1), it is characterized in that having at least the Second Mate to be connected with kelly body (1) by bolt (4), nut (5) with the clamp (2) of slips (3), the feeler lever holes for clamping center of kelly body (1) is respectively 1: 1.5～2 to the center to center distance at two bolts (4) center.
2, clamping device according to claim 1, by last row 1:2, following to arrange 2:1 or upper and lower row all be that 1:2 or upper and lower row are that the relation of 2:1 is fixed to the center to center distance at two bolts (4) center at the feeler lever holes for clamping center that it is characterized in that kelly body (1).
