Abstract
The utility model discloses a double bottom drags for husky fill bottom door locking device that opens and shuts relates to the locking device that opens and shuts who digs for the rig double bottom soon and drag for husky drilling bucket bottom door. It solves traditional bottom door to open and shut locking device and utilize the connecting rod to connect the bottom door couple, and when rig unit head lower extreme flange was touched on the connecting rod top, the bottom door was opened to the couple ring that the couple is thrown off on the bottom door, can not satisfy the open and shut problem of locking of bottom door that the drilling bucket can't touch rig unit head lower extreme flange. The utility model discloses a couple, center pin on the couple ring, characterized by are connected to the couple ring sum of fixing on the drilling bucket bottom door: have couple support housing at the drilling bucket internal fixation, the couple is fixed on couple support housing through the center pin, and tilting fixed has a spring steel sheet between couple and the couple support housing, is equipped with the elasticity stopper between couple and the drilling bucket inner tube wall, is connected with in the upper end of couple and opens the spanner. The utility model discloses simple structure, bottom door locking reliably guarantee that the drilling bucket bottom door relies on rig locking itself closed.
Description
Technical field
The utility model relates to a kind of Double bottom and drags for husky bucket bottom door opening-closing locking device, specifically relate to the opening-closing locking device that rotary drilling rig Double bottom drags for sand borer bucket bottom door, be applicable to drilling bucket and cannot touch end flanges under rotary digging drill power head, realize a kind of bottom door opening-closing locking device opening bottom door.
Background technology
The bottom door opening-closing locking device that traditional Double bottom drags for sand borer bucket utilizes connecting rod 9 to connect bottom door hook 4, in the upper end of connecting rod 9 by cylindrically coiled spring 10 formula pretension, hook 4 is made to ensure locking drilling bucket bottom door, connecting rod 9 top is relied on to touch end flanges under Spiral digging machine unit head when drilling bucket bottom door is opened, hook 4 is made to throw off hook ring 5 on drilling bucket bottom door, as shown in Figure 1; The device of this structure needs very large opening force could open drilling bucket bottom door.But cannot touch the Double bottom of end flanges under Spiral digging machine unit head for connecting rod 9 top and drag for husky bucket bottom door, traditional drilling bucket bottom door opening-closing locking device can not meet the requirement of drilling bucket bottom door locking.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and a kind of structure proposed is simple, and reliable lock, to take space in bucket little, and the Double bottom can be satisfied with when drilling bucket cannot touch end flanges under drill power head drags for husky bucket bottom door opening-closing locking device.
Technical solution of the present utility model is: locking device comprises the hook ring be fixed on drilling bucket bottom door and the hook, the central axis that are connected on hook ring, it is characterized in that: have hook support housing at drilling bucket internal fixtion, link up with and be fixed on hook support housing by central axis, tilt to be fixed with a steel spring plate between hook and hook support housing, be provided with elastic spacing block between hook and drilling bucket inner tube wall, be connected with Wrench for opening in the upper end of hook.
One end of steel spring plate described in technical solution of the present utility model is bolted on the lower end of hook support housing inwall, and the other end of steel spring plate is connected with the upper-end contact of hook.
Elastic spacing block described in technical solution of the present utility model is located at hook with on the tie point of steel spring plate.
Wrench for opening described in technical solution of the present utility model is placed in the T-shaped hole on drilling bucket barrel, and the lower contact pressure of Wrench for opening is touched on the sidewall of hook upper end.
The elastic force that the utility model relies on the elastic deformation of steel spring plate to produce is applied on hook, ensures that drilling bucket bottom door in drilling process is reliably locked, avoids occurring rotary drilling rig lock of tool drilling because bottom door opens by mistake; The utility model can ensure that drilling bucket bottom door relies on rotary drilling rig locking itself closed, and opening of drilling bucket bottom door relies on manpower to be opened by special tool; The utility model tool has the following advantages: 1, simple, the reliable lock of device, to take space in bucket little; 2, the drilling bucket bottom door can be satisfied with when drilling bucket cannot touch end flanges under rotary digging drill power head is opened; 3, can realize opening drilling bucket bottom door by less power by the length of adjustment Wrench for opening.
Accompanying drawing explanation

Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation that the utility model is fixed on drilling bucket cylinder inboard wall.
Detailed description of the invention
As shown in Figure 2,3, the hook ring 5 that the utility model comprises drilling bucket 8 and is fixed on drilling bucket 8 bottom door, the hook end hook of hook 4 is on hook ring 5, and hook ring 5 is welded on according to the installation site of hook 4 on the bottom door of drilling bucket 8; Barrel in drilling bucket 8 is fixed with hook support housing 7, hook support housing 7 is fixed by welding on the barrel in drilling bucket 8; Hook 4 is fixed on hook support housing 7 by central axis 3, and hook 4 can rotate around this central axis 3; When hook 4 locks hook ring 5, hook support housing 7 lower end contacts with drilling bucket 8 bottom door, and hook support housing 7 can form airtight space, prevents boring mud from entering; Gap between hook 4 and hook support housing 7 is tilted is fixed with a steel spring plate 6, elastic spacing block 2 is provided with between hook 4 and drilling bucket 8 inner tube wall, manually opened spanner 1 is connected with in the upper end of hook 4, Wrench for opening 1 is placed in the T-shaped hole on drilling bucket 8 barrel, the lower contact pressure of Wrench for opening 1 is touched on the sidewall of hook 4 upper end, the A place namely in Fig. 2; One end of steel spring plate 6 is bolted on the lower end of hook support housing 7 inwall, and the other end of steel spring plate 6 is connected with the upper end sidewall contact of hook 4, and elastic spacing block 2 is located at hook 4 with on the tie point of steel spring plate 6; Touch steel spring plate 6 when the upper end of hook 4 to make it to produce elastic deformation, when the precompression of the predeformation generation of steel spring plate 6 is applied on hook 4, elastic spacing block 2 on hook 4 touches on drilling bucket 8 barrel, and hook 4 position when drilling bucket 8 works can not be changed; The material of steel spring plate 6, thickness and width dimensions calculate according to the opening force of drilling bucket 8 bottom door to be determined, to ensure the locking effect of drilling bucket 8 bottom door opening-closing locking device.
Operating principle: the utility model is fixed on drilling bucket 8 cylinder inboard wall, the bottom door locking when drilling bucket 8 works, the utility model and drilling bucket 8 inwall, bottom door form a confined space, can prevent boring mud from entering in the utility model, affect drilling bucket 8 bottom door and open; In drilling bucket 8 bottom door locking process, borer drill rod pressurizes to drilling bucket 8, and the hook ring 5 on drilling bucket 8 bottom door touches hook 4, by sloped contact surface, hook 4 is rotated around central axis 3, and steel spring plate 6 is touched in the upper end of hook 4 to be made it to produce elastic deformation; When hook 4 locks hook ring 5, steel spring plate 6 elastic force discharges, and hook 4 is resetted, and at this moment links up with 4 locking hook rings 5, i.e. drilling bucket 8 bottom door locking; When drilling bucket 8 bottom door needs to open, drilling machine drilling rod promotes drilling bucket 8, makes drilling bucket 8 unsettled, artificial by Wrench for opening 1, and make steel spring plate 6 produce distortion, hook 4 rotates around central axis 3, by drilling bucket 8 bottom door own wt and boring mud weight, opens drilling bucket 8 bottom door.
