Description

Technical Field

[0001] This utility model relates to the field of drilling platforms, and in particular to a lifting drilling platform. Background Technology

[0002] Drilling platforms are commonly used in oilfield production and drilling. By adding lifting devices, the lifting and lowering of the drilling platform can be realized, adapting to different sites for construction and facilitating the maintenance and repair of the drilling platform.

[0003] For example, patent number CN218624834U discloses a drilling platform lifting cylinder, including a base plate, a support plate fixedly provided on the top surface of the base plate, and the bottom surface of the piston rod fixedly connected to the top surface of the support plate. The top surface of the piston rod is fixedly connected to the cylinder body, and a heating wire is fixedly provided on one side of the cylinder body. Four heating wires are fixedly provided, and the four heating wires are respectively fixedly provided on the four outer walls of the cylinder body. By incorporating heating wires—four of which are fixed to the outside of the cylinder—the equipment is designed to prevent mud from adhering to it during operation. The heating wires heat the mud, causing it to detach and ensuring the cleanliness of the equipment. A lifting cylinder is also included, which raises the platform. After raising the platform, the chain wheel limit switch can be released, fixing the platform in the work area and fully exposing it to the ground for easy maintenance. Maintenance does not interfere with drilling operations, improving the equipment's convenience and practicality. Existing lifting drilling platform structures typically use cylinders for height adjustment but lack safety limit mechanisms. In case of cylinder malfunction, the platform's safety and stability are poor, posing a safety hazard. Furthermore, the inability to adjust the platform's area restricts the work of personnel, reducing its practicality.

[0004] Therefore, in view of the existing lifting drilling platform structure, which uses hydraulic cylinders for lifting and adjustment but lacks a safety limit structure, resulting in poor platform safety and stability, a lifting drilling platform with an added locking structure can be designed to ensure safety and stability. Utility Model Content

[0005] To overcome the problems of existing lifting drilling platform structures that use hydraulic cylinders for lifting and adjustment but lack safety limit structures, resulting in poor platform safety and stability.

[0006] The technical solution of this utility model is as follows: a lifting drilling platform, including a base and a platform body. The lower end of the base is provided with a foot, and a positioning sleeve is fixedly installed on the upper side of the base. A positioning rod is slidably installed on the upper end of the positioning sleeve. The lower end of the platform body and the top of the positioning rod are fixedly connected. A lifting cylinder is fixedly installed on the upper end of the base. A displacement groove is opened on the side of the surface of the platform body. The displacement groove is formed by penetrating the platform body from left to right. Movable plates are provided at both ends of the inner side of the displacement groove. One end of the movable plate is slidably connected to the displacement groove. The other end of the movable plate extends to the outer side of the displacement groove and is fixedly installed with a side baffle. A driving component is provided in the displacement groove. An installation plate is provided on the surface of the positioning sleeve. A locking component is provided on the upper end of the installation plate.

[0007] Preferably, the platform body is raised and lowered by a lifting cylinder to achieve adjustment, and a locking component provides safety limit to increase safety. At the same time, the movable plates on both sides can be adjusted to adjust the width of the platform body, increase the working area, and improve practicality.

[0008] Preferably, four positioning sleeves are provided, and the four positioning rods are fixedly connected to the corners of the platform body.

[0009] Preferably, two lifting cylinders are provided on both sides of the base, and the output ends of the two lifting cylinders are fixedly connected to the bottom of the platform body.

[0010] Preferably, guide rails are provided at both the front and rear ends of the inner side of the displacement groove, and the front and rear ends of the movable plate are slidably connected to the guide rails.

[0011] Preferably, the drive assembly includes a double-threaded rod, a mounting base is fixedly installed on the inner side of the displacement groove, the mounting base and the double-threaded rod are rotatably connected, a bevel gear is fixedly installed on the surface of the double-threaded rod on the side of the mounting base, the two ends of the double-threaded rod are respectively threaded to the movable plate, and the threads at the two ends of the double-threaded rod are opposite and have the same pitch.

[0012] Preferably, a drive motor is provided on the front end face of the displacement groove, and a transmission rod is fixedly installed on the output end of the drive motor. The transmission rod is rotatably connected to the displacement groove, and a transmission gear is fixedly installed in the rear end of the transmission rod into the movable plate. The transmission gear is meshed with a bevel gear.

[0013] Preferably, the locking assembly includes a double-headed cylinder, which is fixedly connected to a mounting plate. Locking plates are installed at both ends of the double-headed cylinder. Guide seats are installed on both sides of the upper end of the mounting plate. The locking plates and guide seats are slidably connected.

[0014] The beneficial effects of this utility model are:

[0015] 1. This lifting drilling platform uses a lifting cylinder to move the platform body up and down to achieve adjustment. When the platform body moves, the positioning rod slides in the positioning sleeve to achieve synchronous limit. The double-headed cylinder pushes the locking plate to move, so that the locking plate enters the locking hole to lock and increase safety.

[0016] 2. This lifting drilling platform uses a drive motor to rotate the transmission rod, which in turn rotates the transmission gear. The bevel gear synchronously drives the double-headed threaded rod to rotate, which can drive the movable plate to move outward, increasing the width of the platform body and improving its practicality.

Four positioning sleeves 3 are provided, and the four positioning rods 4 are respectively fixedly connected to the corners of the platform body 5. A lifting cylinder 6 is fixedly installed at the upper end of the base 1. A displacement groove 7 is formed on the side of the surface of the platform body 5, penetrating the platform body 5 from left to right. The displacement groove 7 has movable plates 8 at both ends on its inner side. One end of the movable plate 8 is slidably connected to the displacement groove 7, and the other end of the movable plate 8 extends to the outside of the displacement groove 7 and is fixedly installed with a side baffle 9. A drive assembly is installed in the displacement groove 7, and an mounting plate 10 is installed on the surface of the positioning sleeve 3. A locking assembly is installed at the upper end of the mounting plate 10. The platform body 5 is moved up and down by the lifting cylinder 6 to achieve adjustment, and the locking assembly provides safety limit to increase safety. At the same time, the movable plates 8 on both sides can be adjusted to adjust the width of the platform body 5, increase the activity area, and improve practicality.

[0025] Please see Figure 1 In this embodiment, two lifting cylinders 6 are provided on both sides of the base 1. The output ends of the two lifting cylinders 6 are fixedly connected to the bottom of the platform body 5. The lifting cylinders 6 are used to push the platform body 5 to move up and down, which facilitates the adjustment of the platform height.

[0026] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, guide rails 71 are provided at both the front and rear ends of the inner side of the displacement groove 7. The front and rear ends of the movable plate 8 are slidably connected to the guide rails 71. The driving assembly includes a double-ended threaded rod 81. A mounting base 82 is fixedly installed on the inner side of the displacement groove 7. The mounting base 82 and the double-ended threaded rod 81 are rotatably connected. A bevel gear 83 is fixedly installed on the surface of the double-ended threaded rod 81 on the side of the mounting base 82. The two ends of the double-ended threaded rod 81 are threadedly connected to the movable plate 8. The threads at the two ends of the double-ended threaded rod 81 are opposite and have the same pitch. A drive motor 84 is provided on the front end of the platform 7. A transmission rod 85 is fixedly installed on the output end of the drive motor 84. The transmission rod 85 is rotatably connected to the displacement groove 7. The rear end of the transmission rod 85 extends into the movable plate 8 and a transmission gear 86 is fixedly installed thereon. The transmission gear 86 and the bevel gear 83 are meshed and connected. The drive motor 84 drives the transmission rod 85 to rotate. The meshing of the transmission gear 86 and the bevel gear 83 can synchronously drive the double-headed threaded rod 81 to rotate, so that the movable plates 8 on both sides can move, adjust the width of the platform body 5, and improve practicality.

[0027] Please see Figure 1 and Figure 5In this embodiment, the locking assembly includes a double-headed cylinder 101, which is fixedly connected to a mounting plate 10. Locking plates 102 are installed at both ends of the double-headed cylinder 101. Guide seats 103 are installed on both sides of the upper end of the mounting plate 10, located on both sides of the double-headed cylinder 101. The locking plates 102 and the guide seats 103 are slidably connected. A locking hole 104 is opened on the surface of the positioning rod 4. The end of the locking plate 102 away from the double-headed cylinder 101 is connected to the locking hole 104 by a pin. When the platform body 5 moves up and down, the positioning rod 4 slides in the positioning sleeve 3 to achieve synchronous limiting. The double-headed cylinder 101 pushes the locking plate 102 to move, so that the locking plate 102 enters the locking hole 104 to achieve limiting and increase safety.

[0028] During operation, after the equipment platform is installed, the lifting cylinder 6 pushes the platform body 5 to move up and down to achieve adjustment. While the platform body 5 is moving up and down, the positioning rod 4 slides in the positioning sleeve 3 to achieve synchronous limiting. The double-headed cylinder 101 pushes the locking plate 102 to move, so that the locking plate 102 enters the locking hole 104 to achieve limiting and increase safety. At the same time, the drive motor 84 drives the transmission rod 85 to rotate. The meshing of the transmission gear 86 and the bevel gear 83 can synchronously drive the double-headed threaded rod 81 to rotate, so that the movable plates 8 on both sides move to adjust the width of the platform body 5 and improve practicality.

[0029] Through the above steps, the platform body 5 is moved up and down by the lifting cylinder 6 to achieve adjustment, and is safely limited by the locking component to increase safety. At the same time, the movable plates 8 on both sides can be adjusted to adjust the width of the platform body 5, increase the working area, and improve practicality. This solves the problem that the existing lifting drilling platform structure, which achieves lifting and adjustment through cylinders, lacks a safety limit structure, resulting in poor platform safety and stability.
