Description
Technical field
The present invention relates to mechanical unlocking mechanism, relate in particular to a kind of unlocking mechanism that drags for the small-bore bucket of sand hopper for rotary drilling rig.
Background technology
Rotary drilling rig is the heavy caliber high efficiency pore-forming equipment that uses in a kind of foundation construction, and its utilization remains that the drilling rod of vertical direction directly rotates excavation over the ground, thereby forms fast the stake hole of required diameter and the degree of depth on ground.This rotary drilling rig is because power is large, power is strong, easy to use, pore-forming is quick, so be widely used in the foundation construction process of engineering construction.The unlocking mechanism that drags for sand hopper of existing Spiral digging machine is very dumb, and difficult processing.In the rotary drilling rig drilling process, earth, sandstone etc. enters in the cylinder from the base plate mouth, and constantly pushes, impacts unlocking mechanism.When the proposition drilling bucket carried out casting, unit head pressed down the platen nut, and latch hook is rotated, but the rotation of latch hook can be subject to the frictional resistance of an interior earth, sandstone etc. equally.Therefore and easily there was a mechanical failure so in the use procedure of drilling bucket, unlocking mechanism is easy to distortion, and, cause the job stability of unlocking mechanism and life-span to be had a strong impact on.
The utility model content
A kind of unlocking mechanism that drags for the small-bore bucket of sand hopper for rotary drilling rig that the utility model provides its objective is so that unlocking mechanism is more flexible, and is more stable, realizes prolonging the drilling bucket life-span.
For realizing above purpose, the technical solution adopted in the utility model: a kind of unlocking mechanism that drags for the small-bore bucket of sand hopper for rotary drilling rig, it comprises platen nut (1), spring (2), fender bracket (3), drive link (4), guide holder (5), connecting rod (6), latch hook (7), lock hook seat (8), snap close (9); It is characterized in that: fender bracket (3) is welded on the drilling bucket top board; Spring (2) is loaded in the fender bracket (3), and spring (2) lower end is pressed on the drilling bucket top board, and spring (2) upper end is pressed under the platen nut (1), and spring (2) is fixed in the upper end of drive link (4); The upper end of drive link (4) is connected with platen nut (1) by screw thread, and is spacing by bolt, and the lower end of drive link (4) is passed guide holder (5) and is connected with connecting rod (6) by bolt; Connecting rod (6) is connected with latch hook (7) by bolt, and latch hook (7) is connected with lock hook seat (8) by bearing pin.
The beneficial effects of the utility model: the small-bore bucket unlocking mechanism of sand hopper that drags for described in the utility model is by changing the connected mode between drive link and latch hook, and is so that unlocking mechanism is more flexible, more stable, realize again prolonging the drilling bucket life-span, it is simple in structure, practical, and economical with materials, installs simple.
Description of drawings
Fig. 1 is assembling drawing of the present utility model.
Fig. 2 is the connecting rod front view.
Fig. 3 is the connecting rod top view.
Numerical reference shown in the figure is expressed as: 1. platen nut; 2. spring; 3. fender bracket; 4. drive link; 5. guide holder; 6. connecting rod; 7. latch hook; 8. lock hook seat; 9. snap close.
The specific embodiment
By reference to the accompanying drawings the utility model is done further explaination.
Drag for the small-bore bucket unlocking mechanism of sand hopper and comprise platen nut 1, spring 2, fender bracket 3, drive link 4, guide holder 5, connecting rod 6, latch hook 7, lock hook seat 8, snap close 9; Wherein, fender bracket 3 is welded on the drilling bucket top board; Spring 2 is loaded in the fender bracket 3, and its lower end is pressed on the drilling bucket top board, and the upper end is pressed under the platen nut 1, is fixed in the upper end of drive link 4; The upper end of drive link 4 is connected with platen nut 1 by screw thread, and is spacing by bolt, and the lower end of drive link 4 is passed guide holder 5 and is connected with connecting rod 6 by bolt; Connecting rod 6 is connected with latch hook 7 by bolt, and latch hook 7 is connected with lock hook seat 8 by bearing pin.When filling soil in the drilling bucket, drilling bucket is proposed, unit head presses down platen nut 1, and latch hook 7 is rotated around the connecting hole with lock hook seat 8, and then latch hook 7 and snap close 9 are broken away from, and realizes opening the casting of drilling bucket base plate; Toward ground pressing base plate latch hook 7 is resetted by spring 2 afterwards and close the drilling bucket base plate.Wherein couple together by connecting rod 6 between drive link 4 and the latch hook 7, make the same maintenance when drilling bucket is made soil of whole unlocking mechanism flexible.And this connecting rod 6 is made simple, easy for installation.
Above a kind of unlocking mechanism that drags for the small-bore bucket of sand hopper for rotary drilling rig provided by the utility model is described in detail, herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
