[detailed description of the invention]
As shown in Figures 1 to 7, meet a kind of clamp system 100 of the present utility model and can be used for clamping the column in stake work engineering machinery or tubular equipment, for column or tube are held up straight after squeeze into the end, ground or extract from underground.This clamp system 100 preferable examples in the present embodiment is applied with drill machine with casing, as sub-folder clamping apparatus grip sleeve (not shown).The sleeve pipe of described clamp system 100 for vertically placing from the clamping of horizontal direction force, this clamp system 100 comprises two the arc-shaped clamping bodies 1 be oppositely arranged, and by clamping cylinder 2 that the first bearing pin 4 is connected with clamping body 1.
In the present embodiment, described clamp system 100 comprises two clamping bodies 1 and two clamping cylinders 2, the two ends of each clamping cylinder 2 are connected from different clamping bodies 1 respectively, clamping body 1 and clamping cylinder 2 surround a grasping part 10 roughly circlewise closed, and compression clip locking oil cylinder 2 can make grasping part 10 reduce to such an extent as to clamp aforementioned sleeve pipe.Described clamping body 1 to be hinged by the second bearing pin 5 by the first clamp arm 11 and the second clamp arm 12 and to be formed, described first clamp arm 11 and the second clamp arm 12 can rotate around the second bearing pin 5 respectively, and the other end that the first clamp arm 11 and the second clamp arm 12 install the second bearing pin 5 is provided with the through hole 101 of installation first bearing pin 4.The two ends of described clamping cylinder 2 are respectively equipped with the installing hole 22 that can hold the first bearing pin 4 and pass, and described first bearing pin 4 has at least one end to be fixed on clamping body 1, and therefore clamping cylinder 2 and clamping body 1 can rotate in scope of design around the first bearing pin 4.Preferably, the drill machine with casing meeting the present embodiment has the base (not shown) and one and the relatively-stationary main clamping device (not shown) of this base of a ring-type, and the lower end of described second bearing pin 5 can be fixedly installed on this base to ensure the concentricity with sleeve pipe inside clamping body 1.
Described clamp system 100 also comprises the variable-diameter block 7 be installed on inside clamping body 1 and the holding board 6 be connected between variable-diameter block 7 and clamping body 1, described holding board 6 is roughly cuboid in the present embodiment, be fixed in the draw-in groove 16 that the first clamp arm 11 on clamping body 1 and the second clamp arm 1 offer towards grasping part 10, described variable-diameter block 7 has the sidewall 74 of an arc and the installing hole 70 of through sidewall 74 in the horizontal direction, and described variable-diameter block 7 is fixedly installed on holding board 6 by the bolt (non-label) being positioned at installing hole 70.Preferably, described installing hole 70 has the larger entrance in aperture (non-label) and enters to hold bolt, and has the less outlet in an aperture 73 and pass to allow the screw rod position of bolt.After variable-diameter block 7 is locked on holding board 6, holding board 6 cannot be extracted from draw-in groove 16 again, and in order to realize this object, described holding board 6 and draw-in groove 16 cross section are in the horizontal direction roughly trapezoidal or wedge shape.
When the diameter of sleeve pipe changes according to job site, directly change the model of variable-diameter block 7 to the suitable inner diameter be installed on holding board 6.As shown in Figure 6, the inside wall 74a of variable-diameter block 7a in the horizontal plane be projected as the circular arc that radius is R1; As shown in Figure 7, the inside wall 74b of variable-diameter block 7b in the horizontal plane be projected as the circular arc that radius is R2.Wherein, R1 is less than R2, and therefore variable-diameter block 7b is more suitable for than variable-diameter block 7a being used on the sleeve pipe of thicker diameter, to reach the laminating effect of more mating, makes the clamping of clamp system 100 more firm.Preferably, in the present embodiment, described variable-diameter block 7 top is provided with some fins 71, and described fin 71 is provided with holding section 72 by one end of clamping body 1 to downward-extension, described clamping body 1 is provided with edge clipping 17, and the setting height(from bottom) that edge clipping 17 can locate variable-diameter block 7 is blocked in described holding section 72.
Described clamping cylinder 2 comprises cylinder body 20 and can the piston rod 21 of opposing cylinder 20 back and forth movement, because the environment for use of drill machine with casing is comparatively severe, the sealing of cylinder body 20 that can make the impurity such as the sandstone earth usually dropped on piston rod 21 from top greatly reduce into, therefore meet clamp system 100 of the present utility model and also comprise the cover plate 3 be arranged on clamping body 1, described cover plate 3 comprises the projection 34 that centre projects upwards and the lid edge 33 being positioned at protruding both sides, and described protruding 34 bottom notch are to hold the upper part that the first bearing pin 4 exceeds clamping body 1., the length of cover plate 3 is greater than the length that piston rod 21 exposes cylinder body 20, and therefore, the range of movement of described piston rod 21 does not exceed cover plate 3 view field in the horizontal direction.Described cover plate 3 is provided with pilot hole 31, and screw 32 runs through on the installing hole 11 that to be fixedly installed in by cover plate 3 after pilot hole 31 on clamping body 1, and conveniently install, described screw 32 is installed on same side cover edge 33.When clamping cylinder 2 stretches, described cover plate 3 covers piston rod 21 from top all the time, to play good protective effect, extends the application life of clamping cylinder 2.
Because many places in the present embodiment have employed the connected mode of bearing pin, easy for installation, and because each variable-diameter block 7 can be freely movable with the first clamp arm 11 or the second clamp arm 12, therefore, while compression clip locking oil cylinder 2, the blessing power between clamp system 100 and sleeve pipe (not shown) distributes comparatively evenly reliable.In sum, meet clamp system 100 of the present utility model compared to prior art, there is long service life, operation is simple and reliable, the advantage that the easy to maintenance and scope of application is wide.
