Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling machinery, in particular to an anti-tipping device for a blowout preventer hoisting and moving device. Background Technique

[0002] The blowout preventer hoisting and moving device is a mechanized device specialized for transporting, moving and installing blowout preventers in oil drilling operations. Its forward and backward movement control depends on the walking mechanism. At the actual operation site, considering the layout of ground equipment and operation requirements, it is necessary to extend the oil cylinder in a timely manner to lift the sling shackle to achieve the movement of the equipment, so as to avoid potential collisions with other equipment.

[0003] During the extension of the oil cylinder, due to the temporary imbalance of the center of gravity, it may cause friction or collision between the walking mechanism and the guide rail, causing great damage to the device and the guide rail. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-tipping device for a blowout preventer hoisting and moving device, which solves the technical problem that the existing technology lacks protection against damage to the guide rail when the blowout preventer hoisting and moving device is out of balance.

[0008] An anti-tipping roller, installed on the bearing member;

[0009] At least two bearing retaining rings, spaced on the installation shaft, and a cavity for assembling the bearing member is left between the bearing retaining rings.

[0010] The present application is provided with an anti-tipping roller, which contacts the guide rail during imbalance to avoid sliding friction.

[0011] On the basis of the above technical solution, the embodiment of the present application can also be improved as follows:

[0012] Further, the bearing member is a deep groove ball bearing. The beneficial effect of this step is to ensure the stable movement of the anti-tipping roller.

[0013] Further, an elastic retaining ring is arranged between the end face of the bearing member and the bearing retaining ring. The beneficial effect of this step is to ensure the stability of the assembly of the bearing member.

[0029] Embodiment:

[0030] As Figure 1-2 shown, the present application discloses an anti-tipping device for a blowout preventer hoisting and moving device, which is applied to the blowout preventer hoisting and moving device. Its specific installation position is below the walking guide rail. When an imbalance occurs, the guide rail contacts the outer ring of the roller of the present application, so that the sliding friction is changed into rolling friction, which can better protect the structure of the present application.

[0031] The specific structure of the present application is as follows, including:

[0032] The mounting shaft 1, one end of the mounting shaft 1 is used as the connection end, and the other end is used as the free end to install subsequent bearing parts and other components. That is, as shown in the figure, the left end is the connection end and the right end is the free end; in the present application, the mounting shaft 1 can be an existing shaft part, or a protrusion can be provided on the circumferential surface of the end of the connection end to ensure the stability of the connection;

[0033] The bearing part 2 is arranged at the other end of the mounting shaft 1. The bearing part 2 is matched with the mounting shaft 1 and is used to cooperate with the subsequent anti-tipping roller to rotate, which can change the sliding friction into rolling friction and better protect the moving device;

[0034] The anti-tipping roller 3 is installed on the bearing part 2. In the subsequent imbalance situation, the outer wall of the anti-tipping roller 3 is matched with the bottom side of the guide rail, so as to realize rolling;

[0035] At least two bearing retaining rings 4 are spaced apart on the mounting shaft 1, and a cavity for assembling the bearing member 2 is left between the bearing retaining rings 4. The bearing retaining rings 4 are mainly used to ensure the stability of the entire bearing member 2 after installation, thereby ensuring the stability of the entire device structure.

[0036] Specifically, the bearing member 2 is a deep groove ball bearing, which can ensure the stable rotation of the anti-warping roller 3, thereby improving the stability of movement.

[0037] Specifically, a snap ring 5 is provided between the end face of the bearing member 2 and the bearing retaining ring 4. The snap ring 5 can be one or two, and the number is the same as that of the bearing retaining rings 4, so as to ensure the stability of the entire structure.

[0038] Specifically, a set screw 6 is installed on the bearing retaining ring 4 away from the connection end. The connection between the bearing retaining ring 4 and the mounting shaft 1 can be in a threaded connection. The set screw 6 can further strengthen the assembly stability between the bearing retaining ring 4 and the mounting shaft 1. The specific number can be one or more. If it is one, the set screw 6 cooperates with the left bearing retaining ring 4. If it is more than one, they cooperate with the bearing retaining rings 4 one by one.

[0039] Among them, a stepped section 101 is provided on the mounting shaft 1, and the stepped section 101 cooperates with the bearing retaining ring 4, that is, a stepped section is also provided at the corresponding position of the bearing retaining ring 4 and the stepped section 101 to form a cooperation to ensure the stability of the snap ring 5. Specifically, the snap ring 5 is the left snap ring.

[0040] Specifically, it further includes a cotter spring 7, and the cotter spring 7 is installed at the end of the mounting shaft 1 away from the connection end, mainly playing a protective role to prevent related components from falling off.

[0041] As Figure 3 shown, the present application is installed on a mobile device and is located below the walking guide rail. When the center of the mobile device is unbalanced, the outer ring of the anti-warping roller contacts the guide rail, converting the sliding friction between the guide rail and the walking guide rail into the rolling friction between the guide rail and the anti-warping roller, thereby protecting the guide rail and the walking mechanism, enabling the forward and backward movements after the oil cylinder extends to be safely realized, and reducing potential collisions with other on-site equipment.

[0042] In the description of the present invention, a large number of specific details are set forth. However, it can be understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this specification.
