Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe transportation, in particular to an oil pipe transportation device. Background Art

[0002] In the fields of oil extraction, geological exploration, and oil and gas pipeline construction, oil pipes are key components for transporting oil and gas, and their transportation operations are an important link in ensuring construction efficiency and safety. In existing technologies, oil pipe transportation is mostly carried out by forklift lifting, crane lifting, or manual lifting. However, there are many limitations. For example, large equipment such as forklifts and cranes have poor operating flexibility and are difficult to use in narrow spaces (such as drilling platforms and underground work areas). In addition, the oil pipes are prone to shaking and collision during the lifting process, causing wear or deformation of the pipe body. Manual lifting is only suitable for short and small oil pipes. Not only is the labor intensity high and efficiency low, but it is also easy for the oil pipes to slip due to uneven manpower, causing safety accidents. Although some simple transfer devices are equipped with rollers, they lack adaptive fixing structures and cannot stably clamp oil pipes of different diameters. The oil pipes are prone to loosening and falling off during transportation.

[0003] Therefore, it is necessary to provide a new oil pipe transfer device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0020] See also Figures 1 to 3 An embodiment of the present invention provides an oil pipe transfer device, which includes a center connecting plate 1, an abutting arc plate 4 and an adjusting component 5.

[0021] In the embodiments of the present invention, please refer to Figures 1 to 3 , side frames 2 are fixedly welded on both sides of the middle link plate 1, and each side frame 2 is equipped with a rotatably connected roller 21, and the tail fixing frames of the two side frames 2 are provided with a U-shaped push rod 6;

[0022] The oil pipe transfer device also includes a plurality of annularly distributed abutting arc plates 4 and an adjusting component 5 for driving the abutting arc plates 4 to close or open, and the adjusting component 5 includes a mounting tube 51, which is provided with a plurality of annularly distributed through cavities 51a, and a rotatably connected lead screw 52 is installed in the mounting tube 51, and the lead screw 52 is provided with two symmetrically distributed threaded sections with opposite thread directions, and each threaded section is sleeved with a threaded sleeve 53, and a plurality of annularly distributed and rotatably connected middle support plates 54 are installed on the threaded sleeve 53, and the other end of the middle support plate 54 passes through the through cavity 51a and is rotatably connected to the inner plate surface of the abutting arc plate 4, and the barrel head of the mounting tube 51 is provided with a driving motor 55 for driving the lead screw 52 to rotate.

[0023] It should be noted that the present application uses two as a group. Before the oil pipe is transported, the drive motor 55 is turned on to drive the screw 52 to rotate, so that the two threaded sleeves 53 slide back to back along the screw 52 and are pulled into contact with the curved plate 4 through the middle support plate 54, thereby contacting the curved plate 4 to fit the installation tube 51, so that they can be subsequently inserted into the pipe body from the pipe mouth.

[0024] When transporting the oil pipe, the installation tubes 51 in the two sets of transport devices are respectively inserted into the two end pipe openings of the oil pipe, forming a transport mode of one pulling in front and the other pushing in the back, and then the drive motor 55 is turned on to drive the screw 52 to reverse. Since the screw 52 is provided with two symmetrically distributed threaded sections with opposite thread directions, the two threaded sleeves 53 slide toward each other along the screw 52 and push outward through the middle support plate 54 to abut the arc plate 4, so that the arc plate 4 is abutted to open and abut against the inner wall of the oil pipe, thereby achieving stable abutment and fixation of the inner wall of the oil pipe, avoiding shaking or falling off of the pipe body during transportation, and is suitable for oil pipes of multiple diameters.

[0025] After being transported to the designated area, the oil pipe is placed on the ground through the lifting component 3, and then the driving motor 55 is turned on to make the abutting arc plate 4 fit into the mounting tube 51, thereby completing the unlocking of the oil pipe head, and then the mounting tube 51 can be slid off the oil pipe head. The overall operation is simple and convenient.

[0026] In this embodiment, in order to prevent the drive motor 55 from being damaged, a protective cover for protecting the drive motor 55 can be fixedly installed on the mounting tube 51, thereby reducing the hidden danger of the drive motor 55 being hit by the oil pipe.

[0027] Among them, a wear-resistant rubber pad with a thickness of 3-5mm is pasted on the outer plate surface of the arc-shaped plate 4. The surface of the rubber pad is treated with anti-slip texture. The rubber pad can buffer the clamping force, avoid direct contact between metals, and at the same time enhance friction and improve clamping stability.

[0028] In the embodiments of the present invention, please refer to Figures 1 to 3 A lifting component 3 for adjusting the height of the abutting arc plate 4 is installed on the center link plate 1, and the lifting component 3 includes a threaded rod 31, the threaded rod 31 is rotatably installed on the center link plate 1, and a servo motor 33 for driving the threaded rod 31 to rotate is installed on the threaded rod 31, and a threaded connection seat 35 with a threaded connection is sleeved on the threaded rod 31, and the mounting tube 51 is fixedly installed on the front end surface of the threaded connection seat 35, and a rotatably connected bracket 32 ​​is installed on the rod head of the threaded rod 31, and the support rod of the bracket 32 ​​is fixedly mounted on the side frame 2, and the servo motor 33 is fixedly mounted on the bracket 32 ​​through the frame.

[0029] It should be noted that: initially, the servo motor 33 is turned on to drive the installation cylinder 51 to slide down along the threaded rod 31 until the installation cylinder 51 and the abutting arc plate 4 attached to the installation cylinder 51 can be inserted into the pipe head of the oil pipe. When the abutting arc plate 4 locks the pipe head of the oil pipe, the servo motor 33 is turned on to drive the installation cylinder 51 to slide up along the threaded rod 31, so that the oil pipe can be lifted. Then the two staff members can transfer the oil pipe by pushing the U-shaped push rod 6.

[0030] Therefore, the lifting component 3 drives the threaded rod 31 to rotate through the servo motor 33, driving the threaded connection seat 35 to rise and fall along the threaded rod 31, and then adjusting the height of the abutting arc plate 4 and the mounting tube 51. The oil pipe can be easily lifted from the ground and placed on a truck or bracket, or unloaded from a high place to the ground without the need for additional auxiliary tools, thereby improving operational flexibility.

[0031] Furthermore, a limiting rod 34 is fixedly installed on the center link plate 1, and the limiting rod 34 passes through the through hole opened by the threaded connection seat 35 and is slidably connected to the through hole, thereby improving the stability of the threaded connection seat 35 when sliding on the threaded rod 31.

[0032] Among them, this application is aimed at transporting small oil pipes, which only requires a single device (such as 1.2-2.8m long and a pipe diameter range of 60-150mm).

[0033] The drive motor 55 in the present invention is provided with an independent external control port (such as a physical button or a wireless receiver). The physical button can be set on the U-shaped push rod 6 and electrically connected to the servo motor 33 through a wire. The wire can be routed along the inner wall of the mounting tube 51, and the control port of the drive motor 55 can also extend to the tail of the mounting tube 51 and be exposed at the oil pipe mouth. The operator directly triggers the port button → starts the motor 55 to drive the screw 52 to reverse → abuts against the arc plate 4 to open and fix the oil pipe. The circuits and controls involved in the present invention are all existing technologies and will not be elaborated on here.

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
