Description

Technical Field

[0001] The utility model relates to a special tool for conveniently testing the opening and closing functions of the container spreader's landing pins and adjusting the opening and closing limit positions, belonging to the technical field of container maintenance tools. Background Art

[0002] The post-rotation locking mechanism of the container spreader involves two safety protection functions: mechanical interlock and electrical interlock. For the maintenance and testing of these two interlock functions, it is necessary to test in the environment of the quay crane equipment and the standard container in cooperation, that is, mobilize the reach stacker and flatbed truck to transport the container to the maintenance site, and the driver operates the equipment to make the container spreader fall into the container lock hole, relying on the self-weight of the spreader itself to press down the landing pin, so as to trigger the landing device to open the mechanical interlock and electrical interlock. In this state, test the opening and closing functions of the rotation lock, and whether the opening and closing mechanical positions are in place and whether the electrical interlock limit signal is triggered. If there is a deviation, it is necessary to adjust the rotation lock position and the limit position until the adjustment is in place. The whole adjustment process has the problems of cumbersome preparatory work, long time consumption, resource waste and reduced efficiency, so it is very necessary to make improvements.

[0003] The technical problem to be solved by the utility model is to provide a tool for conveniently testing the opening and closing functions of the container spreader's landing pins. This tool can conveniently test the opening and closing functions and adjust the opening and closing limit positions in an environment without the cooperation of quay crane equipment and standard containers, and no longer requires mobilizing containers and reach stackers and other equipment to participate in the cooperation for maintenance, saving resources, shortening the maintenance time and improving work efficiency.

[0004] The technical solution to solve the above technical problem is:

[0005] A tool for conveniently testing the opening and closing functions of the container spreader's landing pins, which includes a support seat, an adjusting jack rod, a connecting rod and a handle. The support seat is a vertical sleeve, and the inner hole of the sleeve of the support seat is a threaded hole. The adjusting jack rod is a cylindrical stepped rod, with the small-diameter rod of the cylindrical stepped rod at the lower part and the large-diameter rod at the upper part. The small-diameter rod of the stepped rod is a threaded rod, and the thread of the threaded rod matches the threaded hole of the sleeve of the support seat. The small-diameter threaded rod of the adjusting jack rod is screwed into the threaded hole of the sleeve of the support seat, and the threaded rod and the threaded hole are in rotational fit. A horizontal connecting rod is welded on the outer wall of the support seat, and a handle is installed at the rear end of the connecting rod.

[0006] For the above tool for conveniently testing the opening and closing functions of the container spreader's landing pins, the circumferential outer wall of the upper large-diameter rod of the adjusting jack rod is knurled, the rod body of the connecting rod is Z-shaped, and the circumferential outer wall of the handle is knurled.

[0007] The beneficial effects of the utility model are:

[0008] The support base and the adjusting push rod of the present utility model are connected by a screw rod and a threaded hole, and the height of the adjusting push rod can be adjusted to adjust the overall height of the tool; the support base and the adjusting push rod can be placed under the box pin interlocking cap through the connecting rod and the handle to release the mechanical interlocking device; the connecting rod is Z-shaped to avoid interference with the container structure.

[0009] The present utility model has novel design, simple structure, good reliability and light weight. When testing the opening and closing function of the container special spreader or adjusting the opening and closing limit position, it is no longer necessary to mobilize equipment such as containers and reach stackers for cooperation and maintenance, saving resources, shortening the maintenance time and improving the work efficiency.
