Description

Technical Field

[0001] The invention relates to the field of drilling construction equipment, in particular to a vertical shaft drilling rig with a new structure. Background Art

[0002] Against the backdrop of increasingly severe coal mine safety production situation and the accelerated construction of the Sichuan-Tibet Railway, my country's new and renovated vertical shaft projects will continue to increase in recent years and for a long time in the future, which will inevitably bring new opportunities and challenges to the development of drilling equipment and technology.

[0003] The power head (which plays the role of lifting and rotating) and the faucet of the conventional drilling rig are designed in an integrated manner. When the faucet is damaged, the slurry is easy to leak into the gear box of the power head, causing damage to the gear bearing and increasing the maintenance time. In addition, when the drilling rig capacity is large enough, the power head will be very large in size and weight, making it difficult to achieve deflection and complicated to add or subtract the ruler, increasing the difficulty of work. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a new type of vertical shaft drilling machine with a separate faucet and a power component.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a new type of structural shaft drilling rig, including a base, a support frame, a sliding beam, a faucet, a drill rod, a drill rod connecting rod, a turntable and one or more lifting cylinders;

[0006] The support frame is installed on the base, the sliding beam is installed on the support frame for sliding up and down movement, the faucet is installed on the sliding beam, the drill rod connecting rod is installed on the bottom of the faucet, the drill rod and the drill rod connecting rod are detachably connected to each other, the turntable is installed on the base, the drill rod is inserted into the turntable, and the lower end of one or more lifting cylinders is fixed on the support frame, and the upper end is fixed on the sliding beam.

[0007] Furthermore, it also includes a tilting cylinder, and the faucet is installed on the sliding beam in a hinged manner, one end of the tilting cylinder is hinged to the sliding beam, and the other end is hinged to the faucet.

[0008] Furthermore, the base comprises two sealing beams which are arranged parallel to each other and spaced apart, and a sealing flat cart which is slidably mounted between the two sealing beams, and the turntable is mounted on the sealing flat cart.

[0009] Furthermore, the support frame is hingedly mounted on the base and further comprises one or more tilt frame oil cylinders, wherein the lower ends of the one or more tilt frame oil cylinders are hingedly mounted on the base and the upper ends are hingedly mounted on the support frame.

[0010] Furthermore, the support frame includes two vertical rods and one or more horizontal rods connected between the two vertical rods, the lower ends of the two vertical rods are respectively hinged on the base, and the left and right ends of the sliding beam are respectively slidably installed on the two vertical rods.

[0011] Furthermore, the lower ends of the two vertical rods are hinged to the base using the following structure: two first connecting plates are respectively fixed to the lower ends of the two vertical rods, and two second connecting plates are fixed to the base. The two first connecting plates are respectively hingedly connected to the two second connecting plates, and the first connecting plates and the second connecting plates are also respectively provided with pin holes that can be aligned with each other when the support frame is rotated into a vertical state.

[0012] Furthermore, a total of four lifting cylinders are provided, wherein the lower ends of two of the lifting cylinders are fixed on one of the vertical rods, and the lower ends of the other two lifting cylinders are fixed on the other vertical rod.

[0013] Furthermore, two tilting frame oil cylinders are provided, and the upper ends of the two tilting frame oil cylinders are respectively hinged on the two vertical rods.

[0014] Furthermore, it also includes an auxiliary hanger installed on the base.

[0015] Furthermore, the auxiliary suspension includes a support platform installed on the base, a mechanical arm hinged at the lower end to the support platform, and a tilt arm cylinder with one end hinged to the support platform and the other end hinged to the mechanical arm.

[0016] The beneficial effects of the present invention are embodied in:

[0017] The present invention transfers the function of the power head to the sliding beam, the lifting cylinder and the turntable, so that the traditional power head with an integrated design with the faucet is no longer needed, and the faucet and the power component are separated. When the drill rod needs to be lifted, the lifting cylinder is extended, and the lifting cylinder can lift the sliding beam, and then the sliding beam carries the faucet and the drill rod to lift, and the lifting cylinder is shortened to drive the above components back. When the drill rod needs to be rotated, the turntable is started, and the turntable drives the drill rod to rotate. Such a separate design allows the faucet to have a small size and light weight, so that it is easy to achieve deflection, which is conducive to adding and reducing dimensions. The use of a turntable drive instead of a power head torque transmission structure can realize direct drive of a variable frequency motor and improve efficiency. In addition, it can also reduce damage to gear bearings, facilitate maintenance, and save maintenance time.

[0018] The present invention can effectively improve drilling efficiency, reduce construction costs, shorten construction period, and has certain economic and social benefits. BRIEF DESCRIPTION OF THE DRAWINGS
