Abstract
The utility model discloses a drilling bucket latch jack for a rotary drilling machine, which comprises a hydraulic cylinder, wherein gripper arms are hinged on a hydraulic cylinder barrel of the hydraulic cylinder and are connected with a hydraulic cylinder piston rod of the hydraulic cylinder through connecting rods in a hinging way; the three gripper arms are hinged on the periphery of the lower end of the hydraulic cylinder barrel, and each gripper arm is connected with the hydraulic cylinder piston rod through the connecting rod corresponding to the gripper arm in a hinging way; a connecting square tenon is fixedly arranged at the upper end of the hydraulic cylinder barrel; a connecting head is fixedly mounted at the front end of the hydraulic cylinder piston rod; and one end of each connecting rod is connected to the connecting head in a hinging way, and the other end of each connecting rod is connected to each gripper arm in a hinging way. According to the utility model, the connection between the latch jack and a drill rod is convenient with the adoption of the connecting square tenon on the hydraulic cylinder barrel; and the latch jack is convenient to operate, flexible in action and reliable in grabbing, and can accurately grab a drilling bucket falling into a hole on the ground.
Description
Technical field
The utility model relates to a kind of building engineering construction machinery, relates in particular to rotary drilling rig.
Background technology
Rotary drilling rig is the construction machinery of pore-forming operation in a kind of suitable building foundation engineering, is widely used in the ground foundation construction workss such as urban construction, highway bridge, highrise building, cooperates different drilling tools, and it is suitable for the pore-forming operation of dry type or wet type and rock stratum; Rotary drilling rig has that installed power is large, output torque is large, axial compression is large, maneuverability, efficiency of construction is high and multi-functional characteristics.
Rotary drilling rig is in practice of construction, because the soil-geological complicated condition is changeable, pore-forming resistance and change in torque are larger, and the impact that is subjected to other unfavorable execution conditions, drilling bucket, drilling tool can occur inevitably drops in the hole, even drilling rod occurs and twist off at the bottom of the drilling bucket residual pores that forms with wire cable rupture, produce serious economic loss.Impact dark owing to holed and collateral resistance often is difficult to salvage the drilling bucket that comes off, and diver's dive is salvaged then both inconvenient, and is also very dangerous.
The utility model content
For the above-mentioned deficiency of prior art, technical problem to be solved in the utility model provides a kind of Spiral digging machine drilling bucket fisher that can accurately grasp by terrestrial operation drilling bucket in the hole of dropping.
In order to solve the problems of the technologies described above, Spiral digging machine drilling bucket fisher of the present utility model comprises hydraulic cylinder, and hinged on the Barrel of Hydraulic Cylinders of described hydraulic cylinder have a gripping arm, and this gripping arm also is hinged mutually by the hydraulic cylinder piston rod of connecting rod with hydraulic cylinder.
After adopting said structure, because hinged on the Barrel of Hydraulic Cylinders have a gripping arm, and this gripping arm is again by connecting rod and hydraulic cylinder piston rod phase hinge, when salvaging the Spiral digging machine drilling bucket, the hydraulic cylinder piston rod that gos deep into the fisher of bottom, hole stretches out, thereby promotes connecting rod and drive gripping arm to open for the crawl drilling bucket and get ready, during crawl then hydraulic cylinder piston rod retract and the pulling connecting rod, so that gripping arm is closed up, with crawl drilling bucket flange portion, drilling bucket is promoted to ground.Said structure can be realized the drilling bucket in pore-forming crawl is salvaged by terrestrial operation, grasping movement accurately and reliably, the security risk of diver's dive has been avoided in flexible movements, easy to operate,
A kind of preferred embodiment of the present utility model, the lower end periphery hinge of described Barrel of Hydraulic Cylinders has three gripping arms, and each gripping arm all is hinged with hydraulic cylinder piston rod mutually by corresponding with it connecting rod.This structure crawl is reliable, puts forth effort to stablize.
Another preferred embodiment of the present utility model, the upper end of described Barrel of Hydraulic Cylinders is fixedly installed connection side's tenon; Front end at described hydraulic cylinder piston rod fixedly is equipped with connector, and an end of connecting rod is hinged on the connector, and the other end of connecting rod is hinged in the gripping arm.Connection side's tenon on the Barrel of Hydraulic Cylinders makes things convenient for being connected of fisher and drilling rod.The connector of hydraulic cylinder piston rod front end makes it rational in infrastructure, is convenient to installation and maintenance.
Description of drawings
Below in conjunction with the drawings and specific embodiments Spiral digging machine drilling bucket fisher of the present utility model is described in further detail.
Fig. 1 is the main apparent direction structural representation of a kind of specific embodiment of the utility model Spiral digging machine drilling bucket fisher;
Fig. 2 is the top view of structure shown in Figure 1.
Among the figure, 1-Barrel of Hydraulic Cylinders, 2-connection side tenon, 3-hydraulic cylinder piston rod, 4-connector, 5-gripping arm, 6-connecting rod, 7-round nut.
The specific embodiment
In Fig. 1, Spiral digging machine drilling bucket fisher shown in Figure 2, the upper end of Barrel of Hydraulic Cylinders 1 is fixedly installed connection side's tenon 2, and this connection side's tenon 2 is used for being connected with drilling rod.At the cylindrical shell lower end of Barrel of Hydraulic Cylinders 1 peripheral hinged three gripping arms 5 are arranged, these three gripping arms 5 are distributed in the periphery of cylinder barrel cylindrical shell, and gripping arm 5 adopts its ends of bar type structure to be hook-shaped, disturbs the drilling bucket that crawl is dropped so that close.The front end that stretches out at hydraulic cylinder piston rod 3 fixedly is equipped with connector 4 by round nut 7, all is hinged with a connecting rod 6 on three hinged ears of connector 4, and the other end of connecting rod 6 then is hinged in the gripping arm 5.Gripping arm 5 keeps a segment distance at the hinged point on the Barrel of Hydraulic Cylinders 1 and the hinge point of connecting rod 6 in gripping arm 5.
In work progress, when drilling bucket drops in pore-forming, carry out reaming with the drilling bucket that strengthens first and process, and dispose the deposits such as powder fine sand around the drilling bucket top and ovum gravel, with the collateral resistance of removing accident drilling bucket; Then fisher is installed in the drilling rod lower end by connection side's tenon, connects the oil circuit of hydraulic cylinder, the fisher that will open is transferred in the hole, shrinks to close in the time of above arriving drilling bucket and disturbs fisher, and crawl drilling bucket flange proposes ground to the accident drilling bucket.
Above-described only is preferred embodiment of the present invention, should be pointed out that for a person skilled in the art, under the premise of not departing from the present invention, can also make some distortion and improvement.For example: Barrel of Hydraulic Cylinders is fixedly installed in the cylinder barrel installation sleeve, and the lower end of this installation sleeve is provided with flange, and the upper end of installation sleeve is connection side's tenon, etc.These conversion still fall in the protection domain of the present utility model.
