Abstract
The invention relates to a connecting structure between a tripod and a drilling mast of a rotary drilling rig. The structure consists of the tripod, a square shaft, a main shaft, a positioning pin shaft, a bush, a pin shaft assembly and the like. Two ends of the main shaft are connected with the drilling mast through the bush, the middle part of the main shaft is fixed with the square shaft together by means of the positioning pin shaft, and two ends of the square shaft are supported on the tripod through the pin shaft assembly. When the drilling mast is in a vertical state, the gravity of the rotary drilling rig working device and the dynamic load generated during operating are transferred to the main shaft through the bush in a drilling mast square box and then transferred to the square shaft by the main shaft. Once the front end face of the drilling mast is not vertical to the ground, the main shaft and the drilling mast generate a sliding tendency; when the front end face of the drilling mast inclines to the ground in a small angle, the drilling mast and the square shaft are directly contacted; and because the main shaft is connected with the square shaft to form a whole, the stress conditions of the contacted parts are greatly improved, and any part is not damaged during the operation of the drilling rig.
Description
Technical field
The present invention relates to various rotary drilling rigs, bore the syndeton between mast and the tripod, particularly be applicable to middle-size and small-size rotary drilling rig band drilling rod travel position, its complete machine height dimension requires extremely strict occasion.
Background technology
At present, rotary drilling rig bores the syndeton between mast and the tripod, has " cross axle " and " square shaft " two kinds of complete multi-form structures.With regard to the comparatively compact square axle structure of its height dimension, because of simple in structure, easy to maintenance, by extensively with should be in the structure design of various rotary drilling rigs.
In the structure of square shaft, the key component square shaft connects the bearing pin assembly 1 that fuses with tripod respectively and is fixed on the bearing pin assembly 2 that bores on the mast.Along with boring the difference that mast is put posture between operational period, the stress between square shaft and the bearing pin assembly 2 can change a lot.Bore mast and be in horizontal level perpendicular to state of ground bearing pin assembly 2, the dynamic load that is produced in ton drilling rod, the gravity that bores mast, drill bit, earth and the operation process surplus in the of 20, radial effect is on bearing pin assembly 2; When the brill mast was in level, this bearing pin assembly almost was not subjected to any external force again, and the gravity that bores component such as mast, drilling rod is directly delivered on the square shaft all by boring the contact plane of mast and square shaft.But when boring mast and be in optional position between the vertical and horizontal, the stress of bearing pin assembly 2 is rather complicated.Square shaft passes to the active force of this bearing pin assembly 2, desire to keep the relative position relation of mast plumbness of boring between the two, and with bore the bearing pin assembly 2 that mast is fixed together, must keep and bore the position relationship between the mast again, along with the change of boring the mast posture, relative position between the two has to again change.Along with the rig prolongation of service time, on the bearing pin assembly 2 with bore the otic placode that mast links together, and the attachment weld between the bearing pin is torn gradually, causes rig to work on.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, reliable and practical, under the constant situation of general structure height dimension, make square shaft be connected the bearing pin stress between the mast and be tending towards rational rotary drilling rig square axle structure with boring.
The object of the present invention is achieved like this: this device is made up of parts such as tripod, pressing plate assembly, bearing pin assembly, brill mast, square shaft, alignment pin, main shaft, linings.The bearing pin assembly is inserted by two different directions in the hole of tripods, and the end of this bearing pin is also inserted square shaft and is equipped with in the hole of lining simultaneously, and two bearing pin assemblies are fixed on the tripod by the pressing plate assembly; Main shaft is connected by lining with boring between the mast, and alignment pin links together main shaft and square shaft, is installed in the inside of brill mast square chest.
Main shaft in the described square axle structure passes square shaft and is installed in and bores the mast square chest and be equipped with in the hole of lining, and by alignment pin keep and square shaft between the position relation.Bore the mast upright state, bore the gravity of parts such as mast, unit head, drilling rod and the dynamic load of generation thereof, pass to main shaft by boring the mast square chest through lining, in the process that brill mast posture changes (as by vertically changing into level), by producing small endwisely slipping between main shaft and the brill mast, make the preceding or rear end face of square shaft realize smooth-going the contact with brill mast square chest inner surface, the gravity overwhelming majority of above-mentioned each parts is directly born by square shaft, and the suffered axial force of main shaft this moment has been reduced to insignificant degree.
During installation, at first lining 1 is put into the endoporus that bores the mast square chest, and then lining 2 is enclosed in the hole at square shaft two ends, put into the square chest that bores mast together with square shaft again, reinstall main shaft, alignment pin successively; Bore the crotch that the mast assembly is put into tripod this moment again being assembled into one, and keep the hole essentially concentric of mount pin axle assembly on the endoporus of square shaft two ends lining 2 and the tripod; And then from the both sides difference mount pin axle assembly of tripod, use the pressing plate assembly to be fixed simultaneously.
Advantage of the present invention is to make full use of limited space, guarantee that component are stressed rationally, the bearing pin assembly is frequently torn in the solution rotary drilling rig work progress, causes the problem of structural failure, has also created necessary condition for various rigs fully reduce shipping height simultaneously.
Be described further below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is one embodiment of the present of invention structure charts.
Fig. 2 is a sectional view among Fig. 1.
The specific embodiment
By bearing pin tripod (1) is linked together with swing arm, the pull bar of rotary drilling rig respectively; Lining 1 (8) packed into from the inboard of boring mast (4) square chest have the hole of seam, lining 2 (9) is packed into earlier in the hole at square shaft (5) two ends, put in the square chest that bores mast (4) together with square shaft (5) again, and keep the through hole of square shaft (5) concentric with lining 1 (8), the main shaft (7) of packing into successively, alignment pin (6); The brill mast (4) that to finish above-mentioned assembling procedure is then put into the crotch of tripod (1), keep tripod (1) installing hole and lining 2 (9) essentially concentrics simultaneously, the bearing pin assembly (3) of packing into from the both sides of tripod (1) respectively, and use pressing plate assembly (2) to be fixed.
Claims (3)
