Abstract
The utility model relates to a double-hoisting-drum hoisting machine of an engineering driller, in particular to a double-hoisting-drum hoisting synchronizing mechanism of the engineering driller. A structure between two hoisting drums of a lifting drill bit of a hoisting machine of an existing impact engineering driller is a bevel gear, the two hoisting drums are not synchronous, the drill bit is prone to inclination, a tower is prone to shake in the impacting process, and a pore-forming effect is not good. The double-hoisting-drum hoisting synchronizing mechanism of the engineering driller is composed of a gear, a main shaft, a left hoisting drum, planetary wheels, a braking hub, a right hoisting drum and a hoisting support frame. The gear is mounted on the main shaft through a key, the main shaft is connected with the braking hub through a flat key, six shaft supporting positions are evenly distributed on the braking hub, each shaft supporting position is provided with one planetary wheel, the left end and the right end of the braking hub are both provided with three planetary wheels, the three planetary wheels at the left end of the braking hub are meshed with an inner gear on the left hoisting drum, and the three planetary wheels at the right end of the braking hub are meshed with an inner gear on the right hoisting drum. The left hoisting drum and the right hoisting drum are both mounted on the main shaft through the bearing. A steel wire rope is wound on the left hoisting drum, a steel wire rope is wound on the right hoisting drum, and the two steel wire ropes are connected with the drill bit.
Description
Technical field
The utility model relates to the double drum winch, twin of engineering driller, specifically a kind of two reel elevator synchronizer gears of engineering driller.Be matched in the impact reverse circulation engineering driller of deep foundation engineering and continuous concrete wall and hydraulic engineering, science of bridge building.
Background technology
The rotation of impacting engineering driller that reverse circulation creeps into and being by reel drives the rope hoisting drill bit, unclamp reel after, the drill bit free fall realizes percussion drilling.The middle structure of two reels that the winch of existing impact engineering driller promotes drill bit is finishing bevel gear cuter, two reels of out of reach winch synchronously, cause two steel wire rope releasing length differences on the drill bit, the problems such as drill bit occurs tilting, and the pylon shake occurs impact process easily, the pore-forming effect is bad, cost of drilling is high.
Summary of the invention
The purpose of this utility model provides a kind of bitubular elevator synchronizer gear of engineering driller, solves the asynchronous problem of the twin drum winch that occurs in the prior art.
The technical solution of the utility model is that the bitubular elevator synchronizer gear of engineering driller is comprised of gear, main shaft, left reel, satellite gear, Sha Che Grains, right reel, winding support; Gear is installed on the main shaft by key; Main shaft is installed on two winding supports by bearing, and winding support is fixed on the rig substructure; Main shaft is connected by flat key with Sha Che Grains; Be evenly equipped with six axle support levels on the Sha Che Grains, a satellite gear is housed on each axle support level, left end and right-hand member respectively are equipped with 3 satellite gears, all by the uniform installation of 120 degree, and 3 satellite gears of left end and the engagement of the inner gear on the left reel; Inner gear engagement on 3 satellite gears of right-hand member and the right reel forms two planet circular systems; Left reel, right reel inner ring are provided with internal tooth, and left reel, right reel all are installed on the main shaft by bearing; Twining respectively steel rope on left reel and the right reel, two wire rope ends connect same impact drill bit.
The beneficial effects of the utility model are, have thoroughly solved the asynchronous problem of reel, use same brake system, can guarantee being synchronized with the movement of steel rope on two reels, remain that duplex type promotes balance.Guarantee not deflection of drill bit when hanging drill bit and impacting, improve hole quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Among Fig. 1: 1 gear, 2 main shafts, 3 left reels, 4 satellite gears, 5 Sha Che Grains, 6 right reels, 7 winding supports.
As can be seen from Figure 1, formed by gear 1, main shaft 2, left reel 3, satellite gear 4, Sha Che Grains 5, right reel 6, winding support 7; Gear 1 is installed on the main shaft 2 by key; Main shaft 2 bearings are installed on two winding supports 7, and winding support 7 is fixed on the rig substructure; Main shaft 2 and Sha Che Grains 5 are connected by flat key; Be evenly equipped with six axle support levels on the Sha Che Grains 5, a satellite gear 4 is housed on each axle support level, left end and right-hand member respectively are equipped with 3 satellite gears 4, all by the uniform installation of 120 degree, and 3 satellite gears 4 of left end and the inner gear engagement on the left reel 3; Inner gear engagement on 3 satellite gears of right-hand member 4 and the right reel 6 forms two planet circular systems; Left reel 3, right reel 6 inner rings are provided with internal tooth, and left reel 3, right reel 6 all are installed on the main shaft 2 by bearing; Twining respectively steel rope on left reel 3 and the right reel 6, two wire rope ends connect same impact drill bit.
During work, power passes to main shaft 2 by gear 1 by key, and main shaft 2 and Sha Che Grains 5 are connected by flat key, so that power reaches Sha Che Grains 5; After checking brake Hub 5, owing to be the principle of work of planet circular system, brake Hub 5 does not rotate, and six satellite gears rotate simultaneously, and three satellite gears in the left side and left reel internally toothed annulus mesh to drive left reel 3 and rotate; The internally toothed annulus of three satellite gears in the right and right reel meshes to drive right reel 6 and rotates; Simultaneously, because six satellite gears are installed on the brake Hub 5 jointly, form differential connection, mutually adjust, restriction left and right sides reel rotates and must act in agreement, and has realized the elevator synchronism of two reels.
