Description

Hard arm elevator Technical Field The utility model relates to the technical field of auxiliary lifting appliances of lifting machinery, in particular to a hard arm lifting machine. Background The hard arm elevator is industrial equipment for carrying materials and is characterized in that a rigid arm structure is adopted, and accurate lifting of heavy objects is realized through rotation, lifting and other actions of a mechanical arm. In the electric hoist crane industry, the hoist upper hook is connected with the hoist trolley, and the hoist lower hook directly lifts the workpiece through the chain, because the inertia of the electric hoist in the walking process, even though the rail trolley or the hoist trolley brakes, the workpiece still swings forwards and backwards or leftwards and rightwards, and therefore, the hard arm lifting mechanism is designed to rigidly connect the workpiece with the flange surface at the lower end of the hard arm lifting machine, so that the swing inertia of the workpiece is counteracted, and the stable carrying of the workpiece is ensured. Disclosure of utility model The utility model aims to solve the problem that stable conveying of a workpiece cannot be guaranteed in the prior art, and provides a hard arm lifting machine. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The hard arm elevator comprises an elevator electric hoist and a trolley platform arranged above the elevator electric hoist, wherein a lifting rod is arranged in the trolley platform in a sliding manner, two symmetrically arranged rib plates are fixedly arranged at the bottom end of the trolley platform through bolts, lifting fixing arms for limiting the moving direction of the lifting rod are fixedly arranged between the two rib plates through bolts, two symmetrically arranged lifting rod stops are fixedly arranged on the lifting rod, a first hook is integrally arranged on the lifting rod stop arranged at the lower end of the lifting rod, a chain is arranged on the elevator electric hoist, and a hoist lower lifting hook arranged in the first hook is fixedly arranged at the bottom end of the chain. Preferably, the bottom end of the lifting rod is fixedly provided with a bearing fixing seat through a bolt, a boring hole is formed in the bearing fixing seat, a rotary bearing is fixedly arranged in the boring hole through a clamp spring, and a rotary shaft is rotatably arranged in the rotary bearing. Preferably, two symmetrically arranged slide rails are arranged on two side walls of the lifting rod, two lifting arm sliding blocks which are vertically arranged are arranged on the slide rails in a sliding mode, and lifting arm fixing plates are fixedly arranged on the outer walls of the lifting arm sliding blocks through bolts. Preferably, the lifting arm fixing plate is fixedly mounted on the outer wall of the lifting fixing arm through bolts. Preferably, two pairs of symmetrically arranged rail trolleys are fixedly arranged at the upper end of the trolley platform through bolts, a second hook is fixedly arranged at the bottom end of the trolley platform, and a hoist lifting hook is sleeved in the second hook. Preferably, the bottom end of the hoist upper lifting hook is fixedly connected with an electric hoist of the hoist, and the hoist upper lifting hook and the hoist lower lifting hook are both rotatably provided with clamping rings. Compared with the prior art, the utility model has the following advantages: According to the utility model, the hoist lower lifting hook is sleeved on the first hook, so that the lifting rod is stopped by the lifting rod to pull the lifting rod to vertically move under the limit of the lifting arm sliding block, the workpiece is prevented from suddenly braking by the track trolley and still swinging forwards and backwards or leftwards and rightwards, and stable carrying of the workpiece is ensured.
