[specific embodiment]
As shown in Figures 1 to 7, meeting a kind of clamp system 100 of the invention can be used for clamping in a work engineering machinery
Column or tubular equipment, for squeezing into ground end after helping column or tube directly or being extracted from underground.The folder in the present embodiment
Tight 100 preferable examples of mechanism apply in drill machine with casing, as sub-folder clamping apparatus grip sleeve (not shown).The clamp system
100 clamp the casing placed vertically for upper force from horizontal direction, which includes two circular arcs being oppositely arranged
Shape clamping body 1, and the clamping cylinder 2 being connect by the first pin shaft 4 with clamping body 1.
In the present embodiment, the clamp system 100 includes two clamping bodies 1 and two clamping cylinders 2, each clamping cylinder
Respectively from the different hinge of clamping body 1 property connections, it is closed that clamping body 1 with clamping cylinder 2 surrounds one in the horizontal direction at 2 both ends
Grasping part 10 substantially circlewise, compression clamping cylinder 2 can be such that grasping part 10 reduces so that clamping aforementioned casing.It is described
Clamping body 1 is hinged by the second pin shaft 5 by the first clamp arm 11 and the second clamp arm 12 and is formed, first clamp arm 11
It can be rotated rotating around the second pin shaft 5 with the second clamp arm 12, the first clamp arm 11 and the second clamp arm 12 install the second pin shaft 5
The other end is equipped with the through-hole 101 of the first pin shaft 4 of installation.The both ends of the clamping cylinder 2 are respectively equipped with and can accommodate the first pin shaft 4 and wear
The mounting hole 22 crossed, first pin shaft 4 at least one end are fixed on clamping body 1, therefore clamping cylinder 2 and clamping body 1 can
It is rotated in scope of design around the first pin shaft 4.Preferably, the drill machine with casing for meeting the present embodiment has a cricoid pedestal (not
Diagram) and one with the relatively-stationary main clamping device (not shown) of the pedestal, the lower end of second pin shaft 5 can be fixedly mounted
Guarantee the concentricity of 1 inside and casing of clamping body on the pedestal.
The clamp system 100 further includes being installed on the variable-diameter block 7 of 1 inside of clamping body and being connected to variable-diameter block 7 and folder
Holding board 6 between tight body 1, the holding board 6 substantially cuboid in the present embodiment are fixed in the on clamping body 1
In the card slot 16 that one clamp arm 11 and the second clamp arm 1 are opened up towards grasping part 10, the variable-diameter block 7 has the side wall of an arc
74 and in the horizontal direction penetrate through side wall 74 mounting hole 70, the variable-diameter block 7 by be located at mounting hole 70 in bolt (do not mark
Number) be fixedly installed on holding board 6.Preferably, the mounting hole 70 has the biggish entrance (not labeled) in aperture to accommodate spiral shell
Bolt enters, and has an aperture is lesser to export 73 to allow the screw parts of bolt to pass through.When variable-diameter block 7 is locked in fixing
After on plate 6, holding board 6 can not be extracted from card slot 16 again, and in order to realize the purpose, the holding board 6 and card slot 16 are in water
Square to section it is substantially trapezoidal shape or wedge-shaped.
When the diameter of casing changes according to construction site, the variable-diameter block 7 that is installed on holding board 6 is directly replaced to suitable
The model of internal diameter.As shown in fig. 6, the inner sidewall 74a of variable-diameter block 7a in the horizontal plane be projected as radius be R1 circular arc
Shape；As shown in fig. 7, the radius that is projected as of the inner sidewall 74b of variable-diameter block 7b in the horizontal plane is the arc-shaped of R2.Wherein, R1 is small
In R2, therefore variable-diameter block 7b is more suitable for imitating using on the casing of thicker diameter to reach more matched fitting than variable-diameter block 7a
Fruit, so that the clamping of clamp system 100 is more firm.Preferably, in the present embodiment, it is equipped at the top of the variable-diameter block 7 several convex
Rib 71, the fin 71 are extended downwardly by one end of clamping body 1 equipped with holding section 72, and the clamping body 1 is equipped with card edge 17, institute
The mounting height of variable-diameter block 7 can be positioned by stating holding section 72 and blocking card edge 17.
The clamping cylinder 2 include cylinder body 20 and can 20 back and forth movement of opposing cylinder piston rod 21, due to drill machine with casing
Use environment it is more severe, the impurity such as sandstone soil usually fallen on piston rod 21 from top can make the sealing of cylinder body 20
Property is substantially reduced into therefore meeting clamp system 100 of the invention further includes the cover board 3 being mounted on clamping body 1, the cover board
3 include the intermediate protrusion 34 projected upwards and the lid edge 33 positioned at raised two sides, and raised 34 bottom notch is to accommodate the
One pin shaft 4 is higher by the upper part of clamping body 1., the length of cover board 3 is greater than the length that piston rod 21 exposes cylinder body 20, therefore,
View field of the motion range of the piston rod 21 without departing from cover board 3 in the horizontal direction.The cover board 3 is equipped with pilot hole
31, cover board 3 is fixedly installed on the mounting hole 11 on clamping body 1 by screw 32 after pilot hole 31, in order to facilitate the installation of,
The screw 32 is installed on same side cover edge 33.When clamping cylinder 2 stretches, the cover board 3 covers piston rod from top always
21, to play preferable protective effect, extend the service life of clamping cylinder 2.
The connection type of pin shaft is used by many places in this present embodiment, it is easy for installation, and since each variable-diameter block 7 is with the
One clamp arm 11 or the second clamp arm 12 can be move freely, therefore while compressing clamping cylinder 2, clamp system 100 and set
The aid power distribution managed between (not shown) is more uniformly reliable.In conclusion meeting clamp system 100 of the invention compared with existing
There is technology, with long service life, operation is simple and reliable, advantage easy to maintenance and wide use scope.
