Abstract
The utility model relates to a holder and a coupling-disconnecting device on an underground pipeline drilling machine, which is formed by a fixedly connected base or a hinged clamping mechanism. The utility model is characterized in that the clamping mechanism is composed of a sliding carriage which is arranged in a shell body, a group of oil cylinder pistons, and a front and a back slip bases. The front slip base is fixed onto the front part of the sliding carriage; the back slip base is fixed onto the end portion of the piston, and an oil cylinder is connected to the back end of the sliding carriage; after the piston causes the back slip base to be butted to a drilling rod, because of reaction force, the oil cylinder is caused to backwards move, and the sliding carriage can cause the front slip base to backwards move and clamp the drilling rod. The clamping mechanism causes stress on both sides of the drilling rod to automatically keep balanced. When the drilling rod is released, the front and the back slip bases can simultaneously disengage from the drilling rod. The utility model has the advantage of simple and reliable structure.
Description
The utility model belongs to non-excavation underground pipeline construction and forms mechanism with the part on the rig, is specifically related to a kind ofly be used to be hinged with or the clamper and the shackle device of dismounting drilling rod.
At present, the pipeline rig that is used for the non-excavation underground pipeline construction, during forming, its structure comprises that a cover is used to be hinged with or the clamper and the shackle device of dismounting drilling rod, its clamper is composed of a fixed connection by clamp mechanism and pedestal, its shackle device is hinge by same clamp mechanism and pedestal and is connected, and change oil cylinder piston on the hinged one group of top that is connected on the body of the tail end of clamp mechanism and form, take this group oil cylinder piston motion and can make clamp mechanism around its clamped drilling rod axle center rotation.The course of work of this cover clamper, shackle device is that the two clamps drilling rod simultaneously, and the shackle device makes it around the drilling rod axle center rotation that clamps by the oil cylinder piston that is connected on the rig body, and the drilling rod that two joints are joined unscrews or screws.The employing two group oil cylinder pistons that the clamp mechanism of this clamper or shackle device has connect forward and backward slip spider (being embedded with slips on the slip spider) respectively, clamp drilling rod to drive forward and backward slip spider.This clamp mechanism heaviness is loaded down with trivial details, bulky, and because two groups of pistons move simultaneously and easily make drilling rod both sides unbalance stress, causes unit head to be subjected to lateral force and influence machinery application life.The employing one group oil cylinder piston actuated one side slip spider that has, the opposite side slip spider is fixed in drilling rod one side, so not only making when clamping drilling rod causes both sides to be subjected to force unbalance, and during releasing orientation, a fixing side slip spider contacts drilling rod all the time, there is friction in drilling rod, therefore influence machinery application life and operating efficiency.
The purpose of this utility model provides clamper and the shackle device on a kind of underground utilities rig that improves structure, makes its service behaviour more reasonable reliable to overcome the shortcoming that said apparatus exists.
The utility model is realized in the following manner:
Clamper is made up of with the clamp mechanism of fixedlying connected with it pedestal; The shackle device is reached with the hinged top commentaries on classics of clamp mechanism oil cylinder piston by pedestal and clamp mechanism hinged with it to be formed.
Described clamp mechanism constitutes as follows: be provided with balladeur train be provided with the housing that biside plate that drilling rod pilot hole rear portion is provided with guide groove forms by cover plate, base plate and middle part in, the rear end of balladeur train is connected on the lug of oil cylinder external diameter, oil cylinder external diameter lug is set in the guide groove of biside plate, preceding slip spider is by the front portion of screw at balladeur train, back slip spider by screw in piston tip, be embedded with slips on the forward and backward slip spider, the balladeur train front end is provided with guide groove, is provided with two ends in the guide groove and is fixedly connected on spacing bearing pin on the biside plate.
Rear end in the back slip spider on base plate is provided with limited block.
The clamp mechanism operating principle of this clamper or shackle device is: when piston will slip spider top, back when contacting push rod, owing to making the mobile backward preceding slip spider of balladeur train tractive that passes through of oil cylinder, moves backward together reaction force, current slip spider contact drilling rod is also stressed during greater than the back slip spider, then piston can make the back slip spider continue forward to move again, all the time keep automatically thus that the drilling rod both sides are stressed to be equated: when piston-retraction makes the back slip spider retreat limited block on being located at base plate, because reaction force moves forward oil cylinder, and slip spider moves forward together before making, and is preceding, back slip spider is separated from drilling rod.
The utility model clamper or shackle device, owing to the structure that its clamp mechanism is designed to be connected by a group oil cylinder piston the forward and backward slip spider of trivial driving, therefore the stressed automatic maintenance balance in both sides when clamping drilling rod can not produce lateral force to drilling rod and unit head; When unclamping drilling rod, forward and backward slip spider all breaks away from drilling rod, and drilling rod is not produced friction.Its reliable working performance helps mechanical application life, and because this structure composition is simple and direct, compact, its device volume is dwindled, and manufacturing cost reduces.
