Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rotary drilling rig equipment maintenance tools, in particular to a tool for taking out bullet heads on a barrel drill. BACKGROUND

[0002] As a kind of efficient pile construction equipment, rotary drilling rig is widely used in various geological conditions, and barrel drill is an important equipment on rotary drilling rig, and a plurality of bullet heads (cutting teeth) are usually installed at the front end of barrel drill, and the feeding of rotary drilling rig mainly relies on bullet heads on barrel drill to apply force to stratum, and bullet heads perform particularly outstanding in hard rock stratum. However, hard rock stratum causes great wear of bullet heads, which leads to frequent damage of bullet heads and requires regular replacement. Since the connection between bullet heads and barrel drill needs to be very tight due to special use environment, it is very time-consuming and laborious to disassemble bullet heads, which not only increases construction cost but also significantly reduces construction efficiency. Therefore, improving the replacement efficiency of bullet heads has become one of the key problems to be solved in the field of rotary drilling rig. At present, in order to meet the demand of taking out bullet heads on barrel drill for replacement, a variety of solutions exist in the market. For example, some construction units use manual tools such as wrenches and hammers to disassemble and install, which is simple and easy to operate, but is time-consuming and laborious in actual operation, has high labor intensity, and is easy to cause fatigue or safety accidents of operators; in addition, some more advanced automatic equipment realizes the rapid replacement of bullet heads through mechanical arms and other automatic devices, but these devices have high cost and are not suitable for all construction environments, especially in narrow space, which is inconvenient to operate and difficult to accurately control the force, and is easy to damage bullet heads.

[0003] Therefore, it is urgent to provide a more convenient and efficient bullet head disassembly tool to overcome the shortcomings of the prior art. CONTENT OF THE INVENTION

[0004] In order to improve the convenience, efficiency and safety of disassembling bullet heads on barrel drill, the present application provides a tool for taking out bullet heads on barrel drill.

[0005] The tool for taking out bullet heads on barrel drill provided by the present application adopts the following technical scheme:

[0006] A tool for taking out bullet heads on barrel drill, comprising a mounting rod, first and second limiters are fixedly arranged at or near both ends of the mounting rod; a striking hammer is slidably arranged on the mounting rod between the first and second limiters, and a first handle is arranged on the striking hammer;

[0007] One end of the mounting rod is fixedly provided with a clamping structure for clamping bullet heads on barrel drill; and a second handle is arranged on the clamping structure.

[0008] In the application, the clamping structure is installed on the mounting rod, one of the first limiting member and the second limiting member is close to the clamping structure, and the other is away from the clamping structure. For example, the first limiting member is installed at the end of the mounting rod away from the clamping structure, and the second limiting member is installed at the end of the mounting rod close to the clamping structure. In use, the operator holds the first handle and the second handle with both hands, uses the clamping structure to be connected at the annular groove or annular step of the bullet head on the rotary drill, moves the impact hammer to the end of the mounting rod close to the clamping structure, and then applies force to the impact hammer through the first handle, so that the impact hammer moves on the mounting rod quickly towards the end away from the clamping structure, and the impact hammer hits the first limiting member away from the clamping structure. The inertia impact force of the impact hammer drives the movement of the mounting rod, and then the impact force is transmitted to the bullet head on the rotary drill through the clamping structure, so that the bullet head is separated from the mounting position of the rotary drill, and the bullet head is quickly disassembled.

[0009] By adopting the above technical scheme, the tool for taking the bullet head on the rotary drill in the application is convenient to use, can more efficiently complete the disassembly and replacement of the bullet head on the rotary drill, and has high safety.

The design that the width of the U-shaped groove of the U-shaped clamping piece gradually decreases from the opening to the bottom enables the tool to better adapt to bullet heads of different diameters when clamping the bullet head on the rotary drill, improving the application range and stability of the tool. At the same time, one end of the connecting rod is fixedly connected to the end of the mounting rod, and the other end is fixedly connected to the side of the U-shaped clamping piece.
