Abstract
The invention provides a telescopic mast drill derrick. A one-arm telescopic mast 2 provided with a top pulley block 1 is sleeved in a double-arm fixed mast 4 through a guide pulley 3; the two sides of the top pulley block of the telescopic mast are respectively connected with a lifting hydraulic cylinder 6 at the upper parts of the double arms of the fixed mast through pin rolls 5; the lower end of the fixed mast is provided with telescopic ground jacks 8 driven by a hydraulic cylinder; the lifting cylinder drives the telescopic mast to stretch out and draw back, and draw the power head of the drill to drill in and lift through a rope pulley mechanism. The derrick is easy to be truck-mounted, is convenient to be conveyed, and is safe and reliable to be operated.
Description
Technical field
The utility model relates to a kind of wagon drill derrick, particularly telescopic topmast rod-type drilling derrick.
Background technology
In the prior art, the wagon drill derrick is whole non-telescoping formula, and for satisfying the needs of drill power head impulse stroke, it is very long that derrick must be done, and whole very long derrick is very disadvantageous to truck-mounted drill rig.The outstanding advantage of truck-mounted drill rig is a maneuverability, and very long derrick has limited this characteristics, and it had both limited on the whole dress, also affected vehicle transport, road running difficulty not only, and be difficult to enter the well site.It has also satisfied the tower requirement because of the bigger moment of resistance needs the enough big hydraulic jack that hoists in addition, has also increased destabilizing factor simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of car dress, convenient transportation, job safety, the reliable telescopic topmast rod bore of operation locomotive derrick of being easy to is provided.
The purpose of this utility model realizes by following measure: a kind of telescopic topmast rod-type drilling derrick, the flexible mast 2 of single armed of top pulleys group 1 is housed, be sleeved in the both arms fixed mast 4 by directive wheel 3, flexible mast top assembly pulley both sides are connected with the lifting hydraulic jack 6 on fixed mast two arm tops with bearing pin 5 respectively, the telescopic outrigger 8 that hydraulic jack 7 drives is equipped with in the fixed mast lower end, lift cylinder drives flexible mast and stretches out, withdraws, and creeps into and promote by rope sheave mechanism traction drill power head.
The left box arm 9 of above-mentioned both arms fixed mast and right box arm 10 are an integral body by top rail 11, lower transverse beam 12 connections, the guide rail 13 that the mast inboard has flexible mast to move up and down.
Above-mentioned flexible mast is a rectangle pillar mast, and its upper end is used to install the top pulleys group by a rectangular flange 14, and both sides are installed three groups of directive wheels 15 respectively, so that make extension mast along surveying guide rail movement in the fixed mast.
Four pulleys 16 of above-mentioned top pulleys group are contained on the same pulley bracket 18 with bearing pin 17 respectively, and the top pulleys group is connected on the flexible mast top rectangular flange with bolt.
Operating principle of the present utility model is: telescopic topmast rod-type drilling derrick is contained on the special-purpose automobile chassis on carriage and the fluid pressure line by hinged bracing frame, a tower hydraulic jack.Wagon drill drives the well site into during work, puts down supporting leg and makes wagon drill prop and be the level of state.The operation hydraulic control valve plays the tower hydraulic jack and drives derrick around the rotation of bracing frame hinge, has level to transfer plumbness to, and fixed arm lower end supporting leg extend out to ground, makes derrick in running order.The flexible mast rise and fall of lift cylinder telescopic drive during operation, and move up and down along flexible mast by fast rope sheave mechanism traction drill power head doubly, thereby realize that rig promotes and creep into operation.
This device provides bigger impulse stroke for drill power head, and overall length is very short during travel position, has not only satisfied drilling well need of work but also convenient vehicle transport.Being contained in two oil cylinders in the derrick fixed mast promotes flexible mast and moves up and down to realize that rig promotes and feed function by fast rope sheave mechanism traction power head doubly.The fixed arm bottom of derrick is provided with telescopic outrigger, makes whole lifting loads of rig directly pass through this supporting leg effect and ground, thereby makes the suffered load of automobile chassis reduce to minimum.
Description of drawings
Accompanying drawing of the present utility model has:
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of fixed mast.
Fig. 3 is the structural representation of flexible mast.
Fig. 4 is the structural representation of head assembly pulley.
The specific embodiment
Embodiment 1: with reference to accompanying drawing is an embodiment of the present utility model.A kind of telescopic topmast rod-type drilling derrick, the flexible mast 2 of single armed of top pulleys group 1 is housed, be sleeved in the both arms fixed mast 4 by directive wheel 3, flexible mast top assembly pulley both sides are connected with the lifting hydraulic jack 6 on fixed mast two arm tops with bearing pin 5 respectively, the telescopic outrigger 8 that hydraulic jack 7 drives is equipped with in the fixed mast lower end, lift cylinder drives flexible mast and stretches out, withdraws, and creeps into and promote by rope sheave mechanism traction drill power head.
The left box arm 9 of above-mentioned both arms fixed mast and right box arm 10 are an integral body by top rail 11, lower transverse beam 12 connections, the guide rail 13 that the mast inboard has flexible mast to move up and down.
Above-mentioned flexible mast is a rectangle pillar mast, and its upper end is used to install the top pulleys group by a rectangular flange 14, and both sides are installed three groups of directive wheels 15 respectively, so that make extension mast along surveying guide rail movement in the fixed mast.
Four pulleys 16 of above-mentioned top pulleys group are contained on the same pulley bracket 18 with bearing pin 17 respectively, and the top pulleys group is connected on the flexible mast top rectangular flange with bolt.
This derrick stroke 7.5m that stretches can make the unit head impulse stroke reach 15m, supporting capacity 800kN.
