[0002] The double-column lift is the product with the most variety and the largest output of Shanghai Yuanzheng Company. The welding parts of the top cover of the double-column lift are connected by a small shaft and the shaft plate through a round of plug welding, and the small shaft is connected to the sliding table support arm through a steel wire rope. The load of the elevator must be transmitted through the small shaft. Once the small shaft falls off due to de-soldering, serious safety accidents will occur

The invention provides a tooling for testing the strength of the welding assembly of the top cover of a lift, comprising: a tooling base, a cylinder support and a cylinder positioning seat installed on the tooling base, a cylinder is placed on the cylinder support and passed through the cylinder positioning seat The positioning is fixed, the cylinder is connected to one end of the wire rope through the connection frame, and the other end of the wire rope is fixed on the wire rope locking plate on the tooling base by going around the wire rope wheel. The quick clamp on the tooling base is clamped and fixed with the support seat of the top cover, and the lever air valve is arranged on the tooling base, and the lever air valve forms a circuit through the compressed air pipe and the cylinder. The strength detection tooling of the welding assembly of the lift top cover provided by the present invention drives the wire rope pulley to act on the small shaft through the large cylinder, and displays the pressure through the pressure gauge. It can conveniently, effectively and accurately test the small size of the double-column top cover under the pressure of 1.5 tons. Shaft welding strength to avoid unqualified products and prevent potential safety hazards.
Description
technical field [0001] The invention relates to the field of lifts, in particular to a tool for testing the strength of a small shaft welded structural part of a top cover of a double-column lift. Background technique [0002] The double-column lift is the product with the most variety and the largest output of Shanghai Yuanzheng Company. The welding parts of the top cover of the double-column lift are connected by a small shaft and the shaft plate through a round of plug welding, and the small shaft is connected to the sliding table support arm through a steel wire rope. The load of the elevator must be transmitted through the small shaft. Once the small shaft falls off due to de-soldering, serious safety accidents will occur. This is the key quality control point of the double-column lift. Since it is not easy to find welding defects after welding and spraying of the top cover welding parts, it is urgent to do a tensile test on the connection strength of the small shaft of...
