Fig. 1 is a schematic view of the overall structure of the present invention.

The reference signs are: 1. a clamp ring; 2. a ball catch body; 3. driving a drill rod; 4. a steel ball; 5. a flat bond; 6. a circular arc groove.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The manual ball clamping type chuck as shown in the attached figure 1 comprises a driving drill rod 3, a plurality of arc grooves 6 which are uniformly distributed are arranged on the outer surfaces of two sides of the driving drill rod 3, a ball clamping body 2 is sleeved on the outer surface of the driving drill rod 3, a steel ball 4 is arranged on the ball clamping body 2, an embedding hole is arranged on the other side of the ball clamping body 2, the steel ball 4 is arranged in the embedding hole, a clamping ring 1 is connected on the outer surface of the ball clamping body 2 in a sliding way, a buffer space groove is arranged at the lower end of the clamping ring 1, a flat key 5 is arranged between the inner surface of the clamping ring 1 and the outer surface of one side of the ball clamping body 2, so that one arc groove 6 is arranged on the driving drill rod 3 at a certain distance, a plurality of steel balls are arranged in the ball clamping body 2 and can move radially, the clamping ring 1 can slide up and down through a handle on the outer surface until the clamping ring abuts against the step of the ball clamping body 2 to press the plurality of steel balls 4 to move inwards, the card plays the clamping action in the embedding hole inslot on initiative drilling rod 3, can rotate the gyrator at this moment, gives initiative drilling rod 3 through hexagonal transmission moment of torsion in the ball card body 2, creeps into the construction operation. The clamping ring 2 slides upwards through the handle, the steel ball 4 falls into a buffer space groove below the clamping ring 1, and at the moment, the driving drill rod is loosened, so that hoisting and hoisting or power head up-and-down operation can be carried out.

The working principle of the utility model is as follows: firstly, through market research, aiming at the construction condition outside a GXY-2KQ type drilling machine and feedback information of a user, the capacity of a gyrator of the GXY-2KQ type drilling machine is still small, firstly, an active drill rod 3 originally used by the GXY-2KQ type drilling machine is 46 x 51, in order to increase the capacity of the gyrator, the gyrator is enlarged by one, the opposite side of the active drill rod 3 is used, the opposite angle is 53 x 59, the two types of the active drill rods are the same as a ball clamping type drilling machine, namely, a steel ball is clamped in a groove of the active drill rod 2 to play a clamping role, in consideration of the strength of the active drill rod, an arc groove 6 suitable for the steel ball 4 is arranged on the active drill rod 3 at intervals of 100mm, the opposite angle of the active drill rod 3 is 59mm, a plurality of steel balls 4 can be adopted, the diameter of the steel balls is set to be 16mm, the steel balls are arranged in the ball clamping body 2 to play a clamping role, a clamping ring 1 can slide up and down through a handle on the outer surface, downwards until the ball clamp body is propped against the step of the ball clamp body 2, the plurality of steel balls 4 are pressed to move inwards, the steel balls are clamped in the embedding hole groove on the driving drill rod 3 to play a role in clamping, and at the moment, the gyrator can be rotated to transmit torque to the driving drill rod 3 through the hexagonal part in the ball clamp body 2, so that drilling construction operation is carried out. The clamping ring 2 slides upwards through the handle, the steel ball 4 falls into a buffer space groove below the clamping ring 1, and at the moment, the driving drill rod is loosened, so that hoisting and hoisting or power head up-and-down operation can be carried out.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
