Description

Structure improved calabash hook assembly Technical Field The utility model belongs to the technical field of machinery, and relates to a hoist hook assembly, in particular to a hoist hook assembly with an improved structure. Background The hoist is a special hoisting device which is arranged on the rails of the I-steel, the rectangular steel and the I-steel and is used for hoisting or loading and unloading heavy objects. The hook component is an important component of a hoist, and structurally comprises a hook and two support plates which are bilaterally symmetrical, wherein guide wheels are rotationally arranged between the upper ends of the two support plates, the middle parts of the two support plates are fixedly connected through studs which are horizontally arranged, the hook comprises a hook body and a connecting rod, the connecting rod is vertically arranged between the lower ends of the two support plates, a stop block is integrally formed at the inner side of the lower end of the support plate, the two stop blocks are stuck together and form a through hole which vertically penetrates through the connecting rod, the upper end of the connecting rod penetrates through the through hole, a baffle ring is integrally formed on the outer wall of the upper end of the connecting rod, the baffle ring and the connecting rod are coaxially arranged, the outer diameter of the baffle ring is larger than the aperture of the through hole, the baffle ring is simultaneously pressed on the two stop blocks, the two stop blocks are fixedly connected with the baffle ring through screws which are vertically arranged, and the two stop blocks are fixedly welded together. When the hook component is assembled, the connecting rod is required to be installed in the through hole, and then the two stop blocks can be fixed. Because two dog pass through the welding mode and link firmly, need to shift couple semi-manufactured goods to the welding station when the equipment, press from both sides tight welding, shift to the equipment station again after the welding is accomplished and carry out subsequent assembly, lead to whole operation process not only loaded down with trivial details, inefficiency moreover. Disclosure of utility model The utility model aims at solving the problems in the prior art and provides a hoist hook assembly with an improved structure, which is convenient to assemble. The utility model discloses a hoist hook assembly with an improved structure, which comprises a hook and two support plates which are bilaterally symmetrical, wherein the two support plates are fixed together through a bolt and nut assembly, the hook comprises a hook body and a connecting rod, a positioning block is arranged between the two support plates, two ends of the positioning block are respectively fixedly connected with the two support plates, a central hole for the upper end of the connecting rod to pass through is formed in the middle of the positioning block, a limit nut is screwed at the upper end of the connecting rod and is pressed on the top of the positioning block, the hoist hook assembly is characterized in that the central hole is a step hole, the central hole consists of a large hole and a small hole matched with the connecting rod, the large hole is positioned above the small hole, a positioning hole radially penetrates through the side wall of the connecting rod, positioning pins matched with the large hole are inserted into the positioning hole, two ends of the positioning pins extend out of the positioning hole, the positioning pins are positioned in the large hole, the length of the positioning pins is larger than the aperture of the small hole, the positioning pins are always limited in the positioning hole under the action of the wall of the large hole, and the lower end of the connecting rod is provided with a limit structure for limiting the upward movement of the hook. In the big hole, the locating pin is limited in the locating hole all the time to set up the length of locating pin and be greater than the aperture of aperture, even make limiting nut drop like this, the locating pin still can support the connecting rod upwards with big hole bottom wall offset, prevents the couple whereabouts, and the security is better. Under the cooperation of limit nut, locating pin and limit structure, under the premise of realizing the stable location and falling prevention of the hook simultaneously, the welding operation can be effectively avoided, so that the assembly steps can be reduced, and the whole assembly process can be completed on the same station, thereby greatly improving the assembly convenience and efficiency. In the above-mentioned improved structure of the hoist hook assembly, the above-mentioned limit structure is a pressing ring sleeved and fixed on the connecting rod, and the pressing ring is pressed against the bottom of the positioning block. By adopting the design, the device has the advantages of sim
