Abstract
The utility model relates to a floating device for a power head drilling rig. The floating device for the power head drilling rig is characterized by comprising a connector and a sleeve; one end of the connector is connected with a transmission part for hanging a power head by a pin shaft; the other end of the connector is arranged in the sleeve in a screwing mode; the connection end between the sleeve and the connector is provided with an anti-loosening screw along the radial direction; a connection rod is arranged in the sleeve in a penetrating mode; a limiting spigot is formed in the sleeve; a limiting ring is arranged at the front end of the connection rod; a spring sleeves the connection rod; the other end of the connection rod is arranged on a lug plate of a power connector support by a cotter pin. By adopting the technical scheme, in the use process, when a drill rod is mounted, the floating device can enable the power head to rotate along with threads of the drill rod and automatically float, so the abrasion between the threads of the drill rod is greatly reduced, the service life of a drill rod joint is prolonged and the construction safety is greatly improved.
Description
Technical field
The utility model belongs to drilling equipment manufacturing technology field, the floating installation that particularly a kind of power head drilling machine is used.
Background technology
Traditional power head drilling machine floating installation is generally connected to the below of unit head, in unsteady, also will conduct moment of torsion.The floating effect that this affects greatly, causes in the process of handling drilling rod, tool joint thread wearing and tearing.The tool joint life-span is reduced, increased operating cost, also have greatly potential safety hazard simultaneously.
Summary of the invention
The utility model for solve the technical problem existing in known technology provide a kind of simple in structure, easy to install, greatly reduce the wearing and tearing between drill rod thread, extend the application life of tool joint, the floating installation that the power head drilling machine of the safety of raising construction is used greatly.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
The floating installation that a kind of power head drilling machine is used, it is characterized in that: comprise connector, sleeve, one end of wherein said connector is connected with the drive disk assembly that hangs unit head by bearing pin, the other end spiral shell of connector is contained in sleeve, and the link of sleeve and connector is radially provided with backing-up screw; In above-mentioned sleeve, be coated with connecting rod, be provided with spacing seam in described sleeve, described connecting rod front end is provided with spacing ring, is set with spring on connecting rod, and the other end of connecting rod is arranged on the otic placode on power sub support by cottor pin.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, in use, when drilling rod is installed, floating installation can make unit head float along with drill rod thread is rotational automatic, can greatly reduce the wearing and tearing between drill rod thread, extend the application life of tool joint, greatly improve the safety of construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, connector; 2, sleeve; 2-1, spacing seam; 3, drive disk assembly connects; 3-1, bearing pin; 4, backing-up screw; 5, connecting rod; 5-1, spacing ring; 6, spring; 7, cottor pin; 8, power sub support; 8-1, otic placode.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, the floating installation that a kind of power head drilling machine is used, comprise connector 1, sleeve 2, one end of wherein said connector is connected 3 by bearing pin 3-1 with the drive disk assembly that hangs unit head, this drive disk assembly generally adopts chain or wire rope to connect, this belongs to known technology, and the other end spiral shell of described connector is contained in sleeve, and the link of sleeve and connector is radially provided with backing-up screw 4; In above-mentioned sleeve, be coated with connecting rod 5, in described sleeve, be provided with spacing seam 2-1, described connecting rod front end is provided with spacing ring 5-1, is set with spring 6 on connecting rod, and the other end of connecting rod is arranged on the otic placode 8-1 on power sub support 8 by cottor pin 7.
When drilling rod is installed, floating installation can make unit head float along with drill rod thread is rotational automatic, can greatly reduce the wearing and tearing between drill rod thread, extends the application life of tool joint, greatly improves the safety of construction.The utlity model has that compact conformation is ingenious, handling ease, low cost and other advantages, extend application life of drilling tool, improved job security and reliability, also reduced operating cost simultaneously.
The above is only to preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
