Description

Technical Field

[0001] The utility model relates to the technical field of oil and natural gas drilling, in particular to a second-layer platform baffle rod device for a drilling rig. Background Art

[0002] Drilling operations are one of the most critical steps in oil and gas well drilling projects. The drilling rig is essential equipment for this operation. During the drilling process, drill pipes need to be frequently raised and lowered. The drilling rig's platform is an important temporary storage area for drill pipes during this process. Drill pipes must be able to enter and exit the platform smoothly. When stored on the platform, it is important to prevent them from accidentally falling out of the platform, disrupting the normal drilling process and causing safety accidents.

[0003] The second-level platform of the drilling rig is located in the middle of the drilling rig. The entry and exit of the drill rod from the second-level platform is a high-altitude operation. It is difficult to manually control the entry and exit of the drill rod from the second-level platform and prevent the drill rod from falling off the second-level platform. Patent No. CN205778614U discloses a hydraulically controlled stop rod device for a V-shaped slide of a power catwalk machine, including a stop rod and a hydraulic cylinder. A rocker arm is installed between the stop rod and the hydraulic cylinder. A sensor is installed on the hydraulic cylinder. A guide block is provided at the connection between the stop rod and the V-shaped slide. An elongated slot is provided at the connection between the rocker arm and the movable pin shaft. One end of the rocker arm is connected to the stop rod by a movable pin shaft, and the other end of the rocker arm is connected to the hinge seat by a rotating pin shaft. The middle of the rocker arm is connected to the hydraulic cylinder piston rod by a joint pin shaft, and the hydraulic cylinder is fixed to the cylinder seat by a cylinder seat pin shaft. This solution controls the lifting and lowering position of the stop rod by hydraulic pressure, which can only achieve movement in one direction and cannot effectively solve the needs of conveniently entering and exiting the second-level platform for the drill rod and preventing the drill rod from falling off due to accidental reasons. Summary of the Invention

[0004] The purpose of this utility model is to address the defects of the existing technology and provide a drilling rig second-layer platform barrier rod device, which can better ensure that the drill rod enters and exits the second-layer platform and prevent the drill rod from falling out of the second-layer platform. It has a simple structure, is safe, efficient, and saves time and effort.

[0005] The utility model provides a drilling rig second-layer platform baffle device, comprising a base assembly (1), a baffle support assembly (2) and a baffle assembly (3), wherein the baffle assembly (3) is hinged to the baffle support assembly (2) along a horizontal rotation direction, and the baffle support assembly (2) is hinged to the base assembly (1) along a vertical rotation direction, and two sides of a special-shaped spring (4) are respectively installed on the baffle assembly (3) and the baffle support assembly (2).

[0006] Preferably, the base assembly (1) includes a base body (101) equipped with a pin shaft (102); the baffle support assembly (2) is hinged to the base assembly (1) via the pin shaft (102) and fixed with a cotter pin (103); the baffle assembly (3) rotates around the axis of the pin shaft (102) together with the baffle support assembly (2), forming two working states, horizontal and vertical, relative to the base assembly (1).

[0007] Preferably, the baffle support assembly (2) comprises a support body (201), on which a spring fixing pin (203) for mounting and fixing the special-shaped spring (4) and a fixing pin shaft (205) for connecting the baffle assembly (3) are mounted; the baffle assembly (3) rotates around the axis of the fixing pin shaft (205) along with the special-shaped spring (4) under the action of an external force, and when the external force disappears, the special-shaped spring (4) automatically resets under the elastic action of the baffle assembly (3).

[0008] Preferably, the support body (201) is further provided with a stop pin (204) for limiting the baffle assembly (3).

[0009] Preferably, the baffle assembly (3) includes a baffle (301).

[0010] Preferably, the baffle is provided with a lifting lug (302).

[0011] Preferably, the base assembly (1), baffle support assembly (2), baffle assembly (3) and special-shaped spring (4) are installed in two groups into two assemblies, which are symmetrically arranged on the second-level platform of the drilling rig.

[0012] The beneficial effects of the utility model are:

[0013] 1. The baffle assembly (3) is hinged on the baffle support assembly (2) along the horizontal rotation direction. When the drill rod enters and exits the second-level platform, the baffle assembly can be horizontally rotated to compress the special-shaped spring to open the baffle assembly, so that the drill rod can easily enter the second-level platform of the drilling rig. When the force disappears, the special-shaped spring drives the baffle assembly to reset. Due to the action of the special-shaped spring and the limiting stop pin, when the drill rod is stored on the second-level platform, it can prevent the drill rod from falling out of the second-level platform due to accidental reasons, affecting the normal progress of drilling and causing safety accidents.

[0014] 2. The baffle support assembly is hinged to the base assembly in the vertical rotation direction, and a lifting lug is provided on the baffle assembly. The baffle support assembly is driven to rotate in the vertical direction through the lifting lug by a lifting device or a transmission mechanism, thereby realizing the conversion between horizontal and vertical working states, meeting the need to move the drill rod out of the second-level platform of the drilling rig.

[0015] 3. The utility model has a simple structure and is easy to operate. It does not require manual operation of the barrier device on the second-layer platform. It can automatically control the rod in and out of the second-layer platform and prevent the drill rod from falling out of the second-layer platform, effectively improving work efficiency and safety.

Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized.

[0026] Example 1

[0027] Figures 1 to 7 The following is a schematic diagram showing the structure of a drilling rig second-level platform barrier rod device provided by a preferred embodiment of the present application. For ease of explanation, only the parts related to this embodiment are shown, which are described in detail as follows:

[0028] A drilling rig second-level platform baffle device includes a baffle assembly 3, a baffle support assembly 2, a base assembly 1, and a special-shaped spring 4. The baffle assembly 3 is installed on the baffle support assembly 2 via a pin shaft, and the baffle support assembly 2 is installed on the base assembly 1 with a pin shaft. Both sides of the special-shaped spring 4 are respectively installed on the baffle assembly 3 and the baffle support assembly 2. The baffle assembly 3 can rotate horizontally around the pin shaft on the baffle support assembly 2 and can be reset under the action of the special-shaped spring 4. The baffle assembly 3 and the baffle support assembly 2 can rotate vertically around the pin shaft on the base assembly 1. The base assembly 1 of the drilling rig second-level platform baffle device is welded to the drilling rig second-level platform 5 and is used to control the entry and exit of the drill rods stored on the drilling rig second-level platform 5 on the drilling rig second-level platform and to prevent the drill rods from falling off the drilling rig second-level platform due to accidental reasons ( Figure 1 and Figure 2 ).

[0029] In one embodiment, the base assembly 1 includes a base body 101 with a pin 102 installed, which is a welded structure. The baffle support assembly 2 is hinged to the base assembly 1 through the pin 102 and fixed with a cotter pin 103 ( Figure 3 ).

[0030] In one embodiment, the baffle support assembly 2 includes a support body 201, which is a welded structure. The support body (201) is equipped with a spring fixing pin 203 for installing and fixing the special-shaped spring 4, a stop pin 204 for limiting the range of movement of the baffle assembly 3, and a fixing pin shaft 205 for connecting the baffle assembly 3, and is fixed with a cotter pin 202 ( Figure 4 and Figure 5 );

[0031] In one embodiment, the baffle assembly 3 includes a baffle 301 as a main body, which is a welded structure and has a lifting lug 302 ( Figure 6 ).

[0032] In one embodiment, the base assembly 1, the baffle support assembly 2, the baffle assembly 3, and the special-shaped spring 4 are assembled into two assemblies in two groups and arranged symmetrically. The two assemblies are symmetrically welded on the second-level platform 5 of the drilling rig.

[0033] The working principle of this device is as follows:

[0034] When the drill rod enters the second-level platform of the drilling rig, the baffle assembly 3 is in a horizontal state. Under the action of the drill rod's own weight, the baffle assembly 3 is pushed to rotate along the axis of the fixed pin shaft 205 (horizontally rotate), compressing the special-shaped spring 4 to open the baffle assembly 3, and the drill rod can enter the second-level platform of the drilling rig. After the drill rod enters the second-level platform of the drilling rig, the baffle assembly 3 automatically resets under the action of the elastic force of the special-shaped spring 4. This cycle repeats, allowing multiple drill rods to enter the second-level platform 5 of the drilling rig.

[0035] When the drill pipe is stored in the second-level platform 5 of the drilling rig, the baffle assembly 3 cannot rotate in the opposite direction along the axis of the fixed pin shaft 205 due to the limiting blockage of the baffle pin 204, thereby preventing the drill pipe from falling out of the second-level platform due to accidental reasons, affecting the normal progress of drilling and causing safety accidents.

[0036] When the drill pipe needs to be moved out of the second floor of the drilling rig, the lifting lug 302 is pulled by the transmission device to drive the baffle support assembly 2 and the baffle assembly 3 to be placed in a vertical working state ( Figure 1 ), multiple drill rods can be moved out of the second floor of the drilling rig without obstruction. After the operation is completed, the baffle support assembly 2 and the baffle assembly 3 are driven by the lifting lug 302 to be placed in a horizontal working state ( Figure 7 ).
