Embodiment 1

[0036]A pressing device includes a winding mechanism 1 , a fixing seat 2 , a pressing pulley 3 , a reversing pulley block 5 and a locking assembly 6 . Wherein, the pressure pulley 3 is arranged between the winding mechanism 1 and the connecting circuit of the fixed seat 2, and the pressure pulley 3 is wound with a steel wire rope 4, and one end of the steel rope 4 is connected with the winding mechanism 1, and the other end of the steel rope 4 is connected with the fixed The seat 2 is connected; the steel wire rope 4 between the connection circuit between the pressure pulley 3 and the winding mechanism 1 and / or the connection circuit between the pressure pulley 3 and the fixed seat 2 is connected by a reversing pulley block 5; the steel wire rope 4 includes the first steel wire rope 41 and the second wire rope 42, the first wire rope 41 is connected with the second wire rope 42 through the lock assembly 6, and is suitable for pressurizing the press pulley 3; the first wire rope...

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is that the reversing pulley also includes a second reversing pulley set arranged between the pressure pulley 3 and the fixed seat 2; The third fixed pulley 53 and the fourth fixed pulley 54 located in the space above the third fixed pulley 53, similarly, as mentioned above, in the vertical direction, the third fixed pulley 53 is located in the space below the pressure pulley 3, and in the horizontal direction There is no restriction in the direction; in the vertical direction, the fourth fixed pulley 54 is located in the space above the third fixed pulley 53, and there is no restriction in the horizontal direction. One end of the wire rope 4 on the pressure pulley 3 is connected with the fixed seat 2 after going around the third fixed pulley 53 and the fourth fixed pulley 54 in turn.

[0050] refer to image 3 with Figure 4 , image 3 -A is a schematic structural view of the pressurizing device arranged on the...

Embodiment 3

[0055] A rotary drilling rig, including the pressurizing device described in Embodiment 1 or Embodiment 2, wherein the winding mechanism 1 includes a reel of the auxiliary hoisting mechanism of the rotary drilling rig and a drive motor connected to the reel; 2 is fixedly arranged on the lower part of the mast 7 of the rotary drilling rig; the pressure pulley 3 is fixedly arranged on the power head 8 of the rotary drilling rig.

[0056] When the rotary drilling rig performs CFA construction, the first steel wire rope 41 and the second steel wire rope 42 are connected through the first buckle 61 and the second buckle 62, and the reel winds the steel wire rope 4 to pressurize the pulley 3, that is, to Power head 8 exerts drilling pressure.

[0057] When the rotary drilling rig is switched to other construction methods, such as the need to lift the reinforcement cage. Now, the first buckle 61 and the second buckle 62 are untied, and the end of the first steel wire rope 41 is conn...

Abstract

The invention provides a pressurizing device and a rotary drilling rig, and relates to the technical field of engineering machinery, and the pressurizing device comprises a winding mechanism, a fixed seat, a pressurizing pulley, a reversing pulley block and a lock catch assembly. The pressurizing pulley is arranged between the winding mechanism and the fixed seat, a steel wire rope is wound on the pressurizing pulley, one end of the steel wire rope is connected with the winding mechanism, and the other end of the steel wire rope is connected with the fixed seat; the steel wire rope between the pressurizing pulley and the winding mechanism and / or between the pressurizing pulley and the fixed seat is connected through a reversing pulley block; the steel wire ropes comprise the first steel wire rope and the second steel wire rope which are detachably connected through a lock catch assembly. The problems that in the prior art, the drilling force of a power head is limited, the number of parts of an additionally-arranged pressurizing device is large, time and labor are wasted in the installation process, and cost is high can be solved, and the power head has the advantages of being simple in structure, reliable in operation, convenient to operate, time-saving and labor-saving in the installation process, low in cost and capable of meeting the application requirements of various construction methods.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a pressurizing device and a rotary drilling rig. Background technique [0002] Due to its advantages of environmental protection, high efficiency, and high single pile bearing capacity, the long helical rotary drilling rig is widely used in foundation construction fields such as housing construction, energy, and transportation. Long helix rotary drilling rig, mainly including chassis, luffing, mast, power head, CFA drill pipe and grouting device and other components; To luffing, the main function is to guide the power head, install winches, oil cylinders and other components; the power head is installed on the mast, and its main function is to provide drilling torque and pressure; the CFA drill pipe is installed on the mast and power head, and its main function is For drilling. [0003] The downward drilling force of the existing long helical rotary drilling rig ...
