Description

Technical Field

[0001] This utility model relates to the technical field of drilling rig auxiliary operation equipment, and in particular to a hydraulic system auxiliary device for vertical shaft drilling rigs. Background Technology

[0002] Vertical spindle drilling rigs, also known as vertical-spindle type drilling rigs, such as the vertical spindle drilling rig disclosed in patent publication number CN113898285A, have a relatively long vertical spindle (about 1 meter) in their rotary mechanism. This spindle drives the drill bit to rotate, achieving feeding and guiding the drill bit, hence the name. The working principle of a vertical spindle drilling rig mainly relies on the rotation of its vertical spindle and its feeding mechanism. The vertical spindle is driven to rotate by a motor or hydraulic system, which in turn drives the drill bit to rotate. Simultaneously, the feeding mechanism enables the drill bit to feed forward, thereby achieving the purpose of drilling. During the drilling process, the guiding function of the vertical spindle ensures that the drilling direction of the drill bit is accurate.

[0003] To ensure the normal operation and extend the service life of a vertical shaft drilling rig, regular maintenance and upkeep are necessary. This includes checking the connections, lubrication, and wear of all components, and promptly cleaning, lubricating, and replacing damaged parts. Simultaneously, it is crucial to adhere to operating procedures and safety precautions during use to prevent accidents.

[0004] The above-mentioned defects are as follows: when changing the construction site of a vertical shaft drilling rig in current geological exploration and construction operations, the unevenness or inclination of the geological terrain makes it difficult to move and transport the drilling rig, which has become a problem and obstacle for geological exploration personnel and affects the efficiency of changing the construction site of the vertical shaft drilling rig. Therefore, a hydraulic system auxiliary device for vertical shaft drilling rigs is proposed to solve the above problems. Summary of the Invention

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 4 As shown, this embodiment provides a hydraulic system auxiliary device for a vertical shaft drilling rig, including a telescopic support column, a cylinder system frame 3, and an auxiliary mechanism 4. The telescopic support column is arranged around the drilling rig frame 1, and the cylinder system frame 3 and the auxiliary mechanism 4 are arranged below the drilling rig frame 1. A hydraulic system is provided inside the cylinder system frame 3, which is used to control the extension and retraction of the telescopic support column. The auxiliary mechanism 4 includes wheels, which are arranged on both sides of the drilling rig frame 1. The wheels are used to support the drilling rig frame 1 after the telescopic support column retracts, so as to facilitate the movement of the vertical shaft drilling rig in uneven or inclined geological conditions and improve the site transfer efficiency.

[0029] In this specific embodiment, as Figure 2 and Figure 3 The front end face of the drilling rig frame 1 has an installation groove 41. The hook plate 42 is slidably inserted into the installation groove 41. A pin 43 passes through the inner top wall of the drilling rig frame 1. The pin 43 is inserted into the installation groove 41 and the hook plate 42 to facilitate the locking and disassembly of the hook plate 42. The pin 43 passes through one side of the hook plate 42. A frosted pad is fixedly connected to the outer side wall of the pin 43. Jacks 2 are fixedly connected to the four corners of the drilling rig frame 1 to support the entire drilling rig frame 1.

[0030] The bottom of the drilling rig frame 1 is provided with a T-slot 45, and the top two sides of the cylinder system frame 3 are provided with T-shaped brackets 46. The T-shaped brackets 46 match the T-slots 45, so that the cylinder system frame can be easily and quickly inserted into the concave guard plate 47. This facilitates the installation and fixing of the cylinder system frame 3, and also protects the cylinder system frame 3 with the concave guard plate 47, reducing the risk of damage to the cylinder system frame 3 from external collisions.

[0031] like Figure 3 and Figure 4The adjustment mechanism 5 includes a slide groove 51, which is located on the side of the drilling rig frame 1. A paddle 52 is slidably disposed in the slide groove 51. A small spring 54 is fixedly connected to one end of the paddle 52, and the small spring 54 generates a continuous pushing force on the paddle 52. An arc-shaped plate 55 is fixedly connected to the end of the paddle 52 away from the small spring 54. An indicator mark is provided on the outer wall of one end of the paddle 52 to indicate the operation method. The end of the small spring 54 away from the paddle 52 is fixedly connected to the inner wall of one side of the drilling rig frame 1. The arc-shaped plate 55 penetrates the inner wall of one side of the T-slot 45 and is engaged with the outer wall of one side of the T-frame 46. The arc-shaped plate 55 limits the T-frame 46 and prevents it from falling off.

[0032] The working principle of the hydraulic system auxiliary device for the vertical shaft drilling rig in this embodiment is as follows:

[0033] When relocation is required, jack 2 is closed to lower the drilling rig frame 1, allowing tires 44 to adhere to the ground and support the drilling rig frame 1. Then, the drilling rig frame 1 is moved and transported as a whole by connecting the hook plate 42 to the existing tractor. Due to long-term use, the hook plate 42 may deform and wear under the influence of large tensile forces. The hook plate 42 is then separated from the hook plate 42 by pulling out the pin 43, and then removed for replacement and maintenance. At the same time, the hydraulic cylinder system frame 3 is protected from collisions by the concave guard plate 47 during transportation and operation. When maintenance is required, the small spring 54 is squeezed by pulling the lever 52. At the same time, the lever 52 moves and drives the arc plate 55 to move. The arc plate 55 moves and separates from one side of the outer wall of the T-shaped frame 46. Then, the hydraulic cylinder system frame 3 is pulled to move the T-shaped frame 46. The T-shaped frame 46 moves and separates from the T-slot 45, allowing the hydraulic cylinder system frame 3 to be disassembled and reassembled.

[0034] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
