Description

Technical Field

[0001] This utility model relates to the field of long spiral drilling rig technology, specifically a long spiral drilling rig lifting device. Background Technology

[0002] The lifting device of a long spiral drilling rig is a key mechanical structure used to lift the main body of the drilling rig from a horizontal or low-angle state to a vertical or working angle state. Through a hydraulic system or mechanical transmission, it provides stable lifting power to the drilling rig, ensuring that the drilling rig can safely and efficiently enter the drilling operation state.

[0003] The lifting device typically uses a motor and traction rope to pull the lifting seat to raise and lower the drill bit. However, in actual operation, due to factors such as the operator's skill level, distraction, or non-standard operating procedures, the lifting height control often fails to be accurate, resulting in excessive lifting of the lifting seat and drill bit. The lifting seat will directly impact the limiting and fixing plate at the top of the lifting device. Since both are rigid structures, they are prone to irreversible plastic deformation under impact, leading to decreased equipment accuracy and structural strength damage, which seriously affects the overall performance and service life of the lifting device. Therefore, a long spiral drilling rig lifting device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a long spiral drilling rig lifting device, which has the advantages of high stability and low risk of impact. It solves the problem that existing lifting devices may cause inaccurate lifting due to operator factors, resulting in excessive lifting of the lifting seat and drill bit, which may then impact the top rigid limiting plate, causing irreversible plastic deformation of both, leading to a decrease in equipment accuracy, structural strength, and damage to overall performance and service life.

[0005] To achieve the above-mentioned goal of high stability and low impact resistance, this utility model provides the following technical solution: a long spiral drilling rig lifting device, including a base plate, a lifting plate on the base plate, a base slidably mounted on the lifting plate, a drilling rig assembly on the surface of the base, and a buffer warning assembly between the lifting plate and the base;

[0006] The buffer warning assembly includes a limiting plate fixedly installed on the surface of the lifting plate, a buffer spring fixedly installed on the surface of the limiting plate, a connecting plate fixedly installed on the top of the buffer spring, a top rod penetrating the limiting plate fixedly installed on the lower surface of the connecting plate, a hydraulic damping rod fixedly installed on the upper surface of the base, a top plate fixedly installed at the output end of the hydraulic damping rod, a contact switch fixedly installed on the lower surface of the limiting plate, a warning light fixedly installed on the top of the connecting plate, and an angle adjustment assembly and a lifting assembly provided on the base plate.

[0007] Furthermore, there are four top rods and four hydraulic damping rods. The top rods slide in contact with the limiting plate, and the bottom of the top rods is located directly above the top plate.

[0008] Furthermore, the drilling rig assembly includes a drilling motor fixedly mounted on the upper surface of the base, and a drill rod penetrating the base is fixedly mounted on the output end of the drilling motor.

[0009] Furthermore, the angle adjustment assembly includes a support plate fixedly installed on the upper surface of the base plate and having a groove on the surface. A connecting block is rotatably installed inside the groove of the support plate. The lifting plate is fixedly installed on the surface of the connecting block. A crossbar is fixedly installed on the upper surface of the base plate. Two hydraulic telescopic cylinders are rotatably installed on the surface of the crossbar. Connecting rods are fixedly installed on opposite sides of the lifting plate. Connecting cylinders are sleeved on the surface of the connecting rods. The telescopic ends of the hydraulic telescopic cylinders are fixedly connected to the surface of the connecting cylinders.

[0010] Furthermore, the lifting assembly is fixedly mounted on a mounting bracket on the upper surface of the base plate. A winch motor is fixedly mounted on the outer surface of the mounting bracket. A rotating shaft that extends through the inner side of the mounting bracket is fixedly mounted on the output end of the winch motor. Two winding wheels are fixedly mounted on the surface of the rotating shaft. A wire rope is fixedly mounted on the surface of the winding wheels. Fixing rods are fixedly mounted on the opposite side of the base. The end of the wire rope away from the winding wheels is fixedly connected to the fixing rod.

[0011] Furthermore, pulleys with annular grooves are rotatably mounted on the opposite side surface of the lifting plate, and the wire rope is located in the annular groove of the pulley.

[0012] Furthermore, two side plates are fixedly installed on the surface of the lifting plate, and a slider is slidably installed between the two side plates. A groove is opened on the opposite side surface of the two side plates, and a protrusion that slides into the groove is fixedly installed on the side surface of the slider. The base is fixedly installed on the surface of the slider.

[0013] Compared with the prior art, the present invention provides a long spiral drilling rig lifting device, which has the following beneficial effects:

[0014] The lifting device of this long spiral drilling rig incorporates a buffer warning component. During the base lifting process, when approaching the limit position, the top rod first contacts the top plate. The hydraulic damping rod and buffer spring work together to buffer the rise of the base, preventing the base and drill bit from directly and rigidly impacting the limit plate when excessively lifted. This effectively reduces irreversible plastic deformation caused by impact force and protects the structural integrity of the equipment. When the base continues to rise and the top plate touches the contact switch, the warning light will illuminate, promptly issuing a warning signal to the operator to pay attention to the lifting height, further ensuring the safe operation of the equipment.

[0023] In this embodiment, the angle adjustment component 6 includes a support plate 61 fixedly installed on the upper surface of the base plate 1 and having a groove on its surface. A connecting block 62 is rotatably installed inside the groove of the support plate 61. The lifting plate 2 is fixedly installed on the surface of the connecting block 62. A crossbar 63 is fixedly installed on the upper surface of the base plate 1. Two hydraulic telescopic cylinders 64 are rotatably installed on the surface of the crossbar 63. A connecting rod 65 is fixedly installed on the opposite side of the lifting plate 2. A connecting cylinder 66 is sleeved on the surface of the connecting rod 65. The telescopic end of the hydraulic telescopic cylinder 64 is fixedly connected to the surface of the connecting cylinder 66.

[0024] In this embodiment, the lifting assembly 7 is fixedly mounted on the mounting bracket 71 on the upper surface of the base plate 1. A winch motor 72 is fixedly mounted on the outer surface of the mounting bracket 71. A rotating shaft 73 that passes through the inner side of the mounting bracket 71 is fixedly mounted on the output end of the winch motor 72. Two winding wheels 74 are fixedly mounted on the surface of the rotating shaft 73. A wire rope 75 is fixedly mounted on the surface of the winding wheels 74. A fixing rod 76 is fixedly mounted on the opposite side of the base 3. The end of the wire rope 75 away from the winding wheel 74 is fixedly connected to the fixing rod 76.

[0025] In this embodiment, pulleys 8 with annular grooves are rotatably installed on the opposite side surface of the lifting plate 2. The wire rope 75 is located in the annular groove of the pulley 8, which facilitates the support of the wire rope 75 and helps to improve the running stability of the wire rope 75.

[0026] In this embodiment, two side plates 9 are fixedly installed on the surface of the lifting plate 2, and a slider 10 is slidably installed between the two side plates 9. A groove is opened on the opposite side surface of the two side plates 9. A protrusion that slides into the groove is fixedly installed on the side surface of the slider 10. The base 3 is fixedly installed on the surface of the slider 10, which facilitates the movement of the base 3 on the surface of the lifting plate 2 and prevents the base 3 from falling off the lifting plate 2.

[0027] It should be noted that in this embodiment, the two hydraulic telescopic cylinders 64 are precisely controlled by a programmable logic controller, and the synchronous movement of the two hydraulic telescopic cylinders 64 is achieved through programming.

[0028] It should be noted that in this embodiment, the contact switch 47 and the warning light 48 are electrically connected by a flexible connecting wire, and the warning light 48 is powered by an external power supply set on the upper surface of the connecting plate 43.

[0029] The working principle of the above embodiments is as follows:

[0030] When drilling assembly 5 needs to be raised for drilling operations, the hydraulic telescopic cylinder 64 is activated. The telescopic end of the hydraulic telescopic cylinder 64 extends and retracts, driving the connecting cylinder 66 and connecting rod 65, thereby causing the lifting plate 2 to rotate around the connecting block 62, thus adjusting the angle of drilling assembly 5. Then, the winch motor 72 in the lifting assembly 7 is activated, driving the rotating shaft 73 to rotate. The two winding wheels 74 on the rotating shaft 73 rotate accordingly, thus releasing and winding the wire rope 75. Under the action of the wire rope 75, the base 3 can move up and down along the lifting plate 2, raising the drilling assembly 5. When the base 3 is raised close to its limit position... The bottom of the top rod 44 will first contact the top plate 46. As the base 3 continues to rise, the hydraulic damping rod 45 is compressed, generating damping force. At the same time, the buffer spring 42 on the surface of the limit plate 41 is also stretched. The buffer spring 42 and the hydraulic damping rod 45 work together to buffer the rise of the base 3 and slow down its rising speed. When the base 3 continues to rise, causing the upper surface of the top plate 46 to touch the contact switch 47 fixedly installed on the lower surface of the limit plate 41, the contact switch 47 is triggered, and the warning light 48 fixedly installed on the top of the connecting plate 43 lights up, issuing a warning signal to remind the operator to immediately stop the lifting operation to prevent further damage to the equipment and ensure the safe operation of the equipment.

[0031] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
