Description

Technical Field

[0001] This invention belongs to the field of petroleum machinery and equipment manufacturing technology, specifically relating to a pinless self-locking platform and a method for arranging the pinless self-locking platform. Background Technology

[0002] A platform is a sheet-like metal component used to construct the drilling platform of an oil drilling rig, providing a working platform for drilling personnel or equipment. It belongs to the steel structure accessories of the drilling rig base. Due to limitations in transportation conditions and the design principles of the drilling rig base steel structure, platforms cannot be designed as a single unit. A complete drilling platform typically requires 10-20 platforms. Depending on the function of the platform, the weight of a single platform generally ranges from several hundred kilograms to several tons. In recent years, with the continuous increase in the height of the drilling rig base, the assembly and disassembly of platforms often need to be carried out at high altitudes. The increased drilling efficiency of drilling rigs has also led to a higher frequency of rig relocation, making the installation and disassembly of platforms a high-risk and arduous task. Summary of the Invention

[0003] The purpose of this invention is to provide a pinless self-locking platform, which achieves pinless assembly through a self-locking mechanism between platforms, reducing the workload during platform installation and disassembly.

[0004] Another object of the present invention is to provide an installation arrangement method for a pinless self-locking platform.

[0005] The first technical solution adopted in this invention is a pinless self-locking laying platform, which includes a laying platform and a positioning mechanism and a self-locking mechanism respectively.

[0006] The first technical solution of this invention is characterized by:

[0007] The platform includes an inner platform, a middle platform, and an outer platform. The inner platform, the middle platform, and the outer platform are each connected to a self-locking mechanism. The inner platform and the middle platform are connected through a self-locking mechanism, and the middle platform and the outer platform are connected through a self-locking mechanism.

[0008] The self-locking mechanism includes a lock groove and a lock rod. The outer platform is connected to the lock rod, the middle platform is connected to both the lock groove and the lock rod, and the inner platform is connected to the lock groove.

[0009] The positioning mechanism includes a stop pin and a positioning ear plate. Positioning ear plates are welded to the bottom of the inner platform, the middle platform and the outer platform respectively.

[0010] The inner platform, the middle platform, and the outer platform are located in the same plane.

[0011] The second technical solution adopted in this invention is a method for installing a pinless self-locking platform, which is implemented according to the following steps: First, the inner platform is installed. The inner platform is connected to the stop pin fixed to the drilling rig base through the positioning ear plate welded to its bottom. Then, the middle platform is installed. The middle platform is connected to the stop pin fixed to the drilling rig base through the positioning ear plate welded to its bottom. At the same time, the locking rod connected to the middle platform is connected to the locking groove connected to the inner platform to form a self-locking mechanism. Finally, the outer platform is installed. The outer platform is connected to the stop pin fixed to the drilling rig base through the positioning ear plate welded to its bottom. At the same time, the locking rod connected to the outer platform is connected to the locking groove of the middle platform to form a self-locking mechanism. At this time, the inner platform and the middle platform are completely locked. The outer platform forms a self-locking mechanism through its own weight and the railings, inclined ladders or ramps installed on the outer platform, thus completing the installation of the platform.

[0012] The beneficial effects of this invention are:

[0013] The pinless self-locking platform and its installation method provided by the present invention realize pinless assembly through the self-locking mechanism between the platforms. During on-site operation, the installation and disassembly of the platform can be completed by lifting equipment alone, which can greatly reduce the workload of the operators during the installation and disassembly of the platform. While reducing labor intensity, it can also save drilling rig relocation time and reduce drilling costs. Attached Figure Description
