Description

Technical Field

[0001] The utility model relates to the field of large-diameter and large-depth vertical shaft construction, in particular to a drilling frame for a deep and large vertical shaft drilling rig. Background Art

[0002] In the fields of coal, gold, iron, lithium and infrastructure, as shaft construction develops towards larger diameters and deeper depths, the shaft drilling rigs required for drilling construction face higher technical requirements. At present, the lifting force and torque of the drilling rig are constantly increasing, and the overall size and weight of the drilling rig are also increasing accordingly. As an important part of the drilling rig, the drilling frame not only bears huge torque and load, but also its structural strength, stability and adjustment accuracy directly affect the safety and efficiency of drilling construction.

[0003] However, there are many problems with the drill rig design in the prior art. First, during the tipping and straightening process of the drill rig, the adjustment of inserting and pulling out the drill rig pin mainly depends on the tipping cylinder. However, due to the poor adjustment accuracy and difficult operation, this process often takes a lot of time and the accuracy of the adjustment cannot be guaranteed. In addition, the existing drill rig design lacks a special adjustment device, which further increases the difficulty and uncertainty of the adjustment. Secondly, there is usually no boss at the pin hole of the existing drill rig. Due to the existence of welding errors, the entire surface of the vertical plate at the pin hole needs to be processed, which not only increases the difficulty and cost of manufacturing, but also may affect the overall strength and stability of the drill rig. At the same time, the drill rig has a poor load-bearing capacity and is prone to deformation, which further affects the safety and efficiency of drilling construction.

[0004] There are some other problems in the existing drilling rig design. For example, the pipeline of the main lifting cylinder can only be arranged from the inside of the drilling rig, resulting in a long section that must be connected with a hose, which not only makes the hose arrangement difficult and messy, but also may affect the normal operation and service life of the cylinder. At the same time, the existing drilling rig lacks a special ladder and standing platform, making it difficult and dangerous for workers to go to the drive unit to work. In addition, the existing drilling rig also lacks integral lifting lugs, and additional lifting lugs need to be welded before lifting, which not only increases the workload, but also may bring safety hazards due to the inability to ensure welding quality.

[0005] Therefore, in view of the problems and shortcomings existing in the prior art, how to improve the structural strength, stability and adjustment accuracy of the drilling rig by improving the structural design and adding specialized functional components, simplify the operation process, and improve construction efficiency and safety. At the same time, how to reasonably arrange pipelines, provide convenient ladders and standing platforms, and reliable overall lifting performance to meet the growing needs of shaft construction and reduce safety risks during construction is an issue that needs to be urgently resolved by technical personnel in this field. Utility Model Content

[0006] The utility model aims to provide a drilling frame for a deep and large vertical shaft drilling rig in view of the problems existing in the background technology.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is to design a drilling rig for a deep and large vertical shaft drilling rig, including a column, an upper ring beam, an intermediate ring beam, a truss beam, a fixing and adjusting device and a lifting lug. The columns are arranged in pairs on the left and right, the two upper ring beams are arranged at the upper ends of the two columns, the two intermediate ring beams are arranged in the middle of the two columns, and the truss beam is installed between the two intermediate ring beams, which improves the strength, rigidity and stability of the drilling rig and can withstand large loads. The fixing and adjusting device is arranged at the lower end of the column for connecting to the bottom bearing support, and the lifting lug is arranged at the upper end of the column for realizing the overall lifting of the drilling rig.

[0008] Furthermore, the upper support of the tipping cylinder is welded to the lower part of the middle ring beam, and is welded symmetrically on the left and right.

[0009] Furthermore, the upper ring beam and the column are connected by flanges, the middle ring beam and the column are connected by flanges, and concave and convex stoppers are arranged at the centers of the upper ring beam, the middle ring beam and the flange centers of the column, which facilitates positioning, has high installation accuracy and can withstand large loads.

[0010] Furthermore, the lifting ear is embedded and welded on the main plate of the column, the lifting ear is chamfered and smoothly transitions to the column to form a whole with the column, two symmetrical reinforcing ribs are arranged on the inner side of the lifting ear, and a heavy plate is welded at the hole of the lifting ear.

[0011] Furthermore, the fixing and adjusting device comprises a stud, an internal thread sleeve, a spacer, a mounting seat plate and a reaction rib plate, the mounting seat plate is welded to the column, the spacer and the internal thread sleeve are welded to the mounting seat plate, and the external thread of the stud cooperates with the spacer. When in use, the lower part of the stud is pressed against the upper surface of the longitudinal beam of the base, and the position of the pin shaft hole of the drilling rack is adjusted by rotating the stud.

[0012] Furthermore, the stud is an integral structure, with an upper portion being a square section, a middle portion being an external thread section, and a bottom portion being a cylindrical section.

[0013] Furthermore, the inner side of the column is a concave structure, and the concave part is a sliding surface. The sliding surface of the arm of the main lifting system slides relative to the sliding surface 7 of the drilling frame.

[0014] Furthermore, the sliding surface is provided with a wear-resistant plate to increase the service life, because during drilling, the torque output by the driving part will cause the sliding surface to fit closely with the sliding surface of the slide arm, which is prone to wear.

[0015] Furthermore, a plurality of hollow holes are provided on the side of the column to reduce the weight of the column itself and also meet the need for routing pipes outside the main lifting cylinder.

[0016] Furthermore, a ladder and a platform for standing are arranged outside the column, and the ladder, the platform for standing and the column are connected by flanges, which are convenient for assembly and disassembly.

[0017] Furthermore, two standing platforms are provided.

[0018] The advantages and beneficial effects of the utility model are:

[0019] The utility model proposes to use a pair of uprights, two sets of upper and lower ring beams and a truss beam as the main structure, thereby improving the structural strength and stability of the drill frame and reducing the weight of the drill frame itself;

[0020] By providing high-strength lifting lugs on the top of the drill rig, the requirements for overall turning over and lifting of the drill rig are met. By providing a fixed adjustment device at the bottom of the drill rig, the pin shaft can be more accurately aligned with the hole during the installation of the drill rig, thus shortening the hole alignment time, reducing the difficulty of hole alignment, and improving the installation efficiency of the drill rig.

[0021] By setting hollow process holes on the drill rig column, the overall weight of the device is reduced. The hollow holes near the bottom can meet the needs of piping on the outside of the main lifting cylinder. The pipeline layout is more beautiful and reasonable, hard pipes can be used for long distances, and the leveling of the main lifting system is better.

[0022] The design of ladder and two standing platforms makes it convenient for operators to climb onto the beam and drive position quickly and safely. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a drilling rig for a deep shaft drilling rig includes two columns 1 arranged in pairs, which are respectively located on the left and right sides of the drilling rig. A pair of upper ring beams 2 are arranged at the upper ends of the columns 1 to enhance the upper structural strength of the drilling rig. Similarly, a pair of intermediate ring beams 3 are arranged in the middle of the columns 1, which work in conjunction with the upper ring beams 2 to further improve the overall stability of the drilling rig. Between the intermediate ring beams 3, trusses 4 are also installed, which help to disperse and withstand the torque from the drill bit, ensuring that the drilling rig can remain stable when subjected to large loads.

[0032] In order to facilitate the installation and positioning of the drilling rig, a fixing and adjusting device 5 is provided at the lower end of the column 1. The device includes a stud 10, an internal threaded sleeve 11, a spacer 12, a mounting base plate 13 and a reaction rib plate 14, etc., which work together to enable the drilling rig to be more accurately aligned with the pin shaft hole during installation, thereby shortening the installation time and reducing the installation difficulty.

[0033] The upper end of the column 1 is also provided with a lifting lug 6, which is designed to be strong enough to meet the requirements of the overall lifting of the drilling rig. The lifting lug 6 is embedded and welded on the main plate of the column 1, and is provided with chamfers and reinforcement ribs to ensure its bearing capacity and service life.

[0034] The inner side of the column 1 is concave, forming a sliding surface 7, which helps the arm of the main lifting system to slide smoothly on the drilling frame. At the same time, a wear-resistant plate 8 is also provided on the sliding surface 7 to extend its service life. A plurality of hollow holes are also provided on the column 1, which not only reduces the weight of the column, but also provides convenience for the pipe routing outside the main lifting cylinder.

[0035] The column 1 of the drilling rig is also provided with a ladder 15 and two standing platforms 16. These facilities provide safe and convenient passages for operators, allowing them to quickly reach the beam and drive position for operation. These ladders and platforms are connected to the column with flanges for easy disassembly and maintenance.

[0036] Workflow: When installing the drill rig for deep shaft drilling rig, firstly, the drill rig is hoisted to the predetermined position by hoisting the lifting lug 6. Then, the drill rig is fine-tuned by using the studs 10 and other components in the fixing adjustment device 5 to ensure that the pin shaft hole is aligned. During the drilling process, the torque of the drill bit is transmitted to the entire drill rig through the upper ring beam 2, the middle ring beam 3 and the truss beam 4, thereby achieving stable and efficient drilling operations. At the same time, the operator can easily reach each operating point for operation and maintenance through the ladder 15 and the standing platform 16.

[0037] The above is a detailed introduction to a drilling rig for a deep and large vertical shaft drilling rig provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
