[0017] like Figures 1 to 7As shown, the self-locking railing base tooling for the corner piece of the hatch cover of the polar transport ship includes a railing 1, a support seat 2, a spring base 3, a pressure spring 4, a support seat bottom plate 7, a spring fixing pin 8 and a support seat locking pin 9. The railing 1 is fixedly installed on the support seat 2 by bolts 5 and nuts 6. The support seat 2 is inserted into the spring base 3 and fixedly connected by the support seat locking pin 9. The pressure spring 4 is fixedly connected to the spring base 3 by the spring fixing pin 8. The support seat bottom plate 7 is installed on the support seat 2. The support seat 2 is provided with a fixing groove 10. The support seat locking pin 9 is inserted into the fixed groove after the support seat 2, the spring base 3 and the pressure spring 4 are connected and installed in sequence. The self-locking railing base tooling is locked in the fixed groove 10. When the self-locking railing base tooling is used, first, the whole set of base devices is assembled, and the support seat 2 is pressed and adjusted until the overall height of the base tooling is lowered to an appropriate position, and then the support seat 2 is rotated to move the support seat locking pin 9 into the locking position, and then the base tooling is inserted into the polar transport ship transport hatch cover corner piece 11 where guardrails need to be set up, and the support seat 2 is rotated to make the support seat locking pin 9 out of the locked state, and the upward elastic force of the pressure spring 4 is used to lift the support seat 2, so that the support seat bottom plate 7 is in close contact with the adjacent structure inside the hatch cover corner piece 11 and a large static friction force is formed, so as to realize the whole base The locking function is used, and finally the fixed railing 1 is inserted and fixed with bolts 5 and nuts 6 to complete the installation of the railing base. Before using the tooling to erect the scaffolding guardrail, the railing, railing base, railing cable and other materials should be assembled in place in advance according to the number and position of the corresponding hatch cover corner fittings, so as to prepare for the rapid installation and use when the guardrail is erected. The connection and fixing method of the self-locking railing base tooling and the corner fitting is to rotate the angle after insertion, and then the support seat 2 is lifted by the rebound of the pressure spring 4, so that the support seat bottom plate 7 is in close contact with the internal structure of the hatch cover corner fitting 11 and a large static friction force is formed, so as to realize the entire base tooling and the corner fitting. Fixed, the railing 1 can be inserted and connected after the installation of the base tooling is completed. Corresponding handrails, railing cables and other accessories need to be set on the railing 1 to form an integral guardrail. The tooling can be operated by one person, and the self-locking railing base only needs to be assembled once. Except for repairing and replacing its internal pressure spring 4, it needs to be disassembled and disassembled. In the remaining stages, it can be regarded as an integral tooling part to participate in the erection of the guardrail. The railing base tooling can greatly reduce the number of guardrail erection personnel, construction time and the amount of guardrail materials. It has a simple structure and is easy to operate. It makes full use of the construction site environment and can meet the on-site guardrail erection needs of rapid construction and large-scale erection and dismantling.

[0018] The self-locking railing base tooling of the present invention is aimed at solving the problems of high time consumption, high material volume, high labor cost, etc. when using traditional scaffolding erection methods in such specific environments. The tooling can also be applied to the corner fittings at the four corners of polar transport ships. For example, when the polar transport ship needs maintenance, painting, etc., workers can also use the self-locking railing base to erect guardrails when working on the top of the polar transport ship. The tooling has low manufacturing cost and is easy and quick to install. If it is widely used in polar transport ships and polar transport ship maintenance operations, it can achieve greater benefits in reducing operating costs, improving construction efficiency, and reducing manpower input.
