Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] Such as figure 2 As shown, the chassis of the lifting equipment adopts a double-layer steel plate 101 structure, and two bearings 103 ensure the good stability of the main support rod 104, and are perpendicular to the ground. Under the action of the rotary motor 106, the main arm 301 is driven within a range of 360 degrees turn. The combination of four independent driving motors 108 and the road wheels 109 can realize the straight forward and backward actions of the whole machine, and realize the turning function by controlling the speed of the motors. The chassis concentrates most of the weight of the whole machine, so that the overall center of gravity of the whole machine is moved down and the stability is improved. Six telescopic legs...

The invention belongs to the field of medium and small tonnage hoisting operation and discloses double-swinging-arm hoisting equipment. The double-swinging-arm hoisting equipment comprises a chassis, a hoisting mechanism, a double-swinging-arm rotation mechanism and a swinging arm variable-amplitude mechanism, wherein the hoisting equipment is connected with heavy objects through lifting hooks on two symmetrical swinging arms, and through cooperation of the hoisting mechanism, the double-swinging-arm rotation mechanism and the swinging arm variable-amplitude mechanism, the heavy objects at the two ends can be hoisted and put in place at the same time by different angles and different quantities according to the actual operation requirements. According to the double-swinging-arm hoisting equipment, the overall structure is simple, and maneuverability is high; under the conditions that medium and small-sized heavy objects are carried by a short distance on the construction site and in factory warehouses and railways or highways are maintained, the assembly operation can be achieved through the double swinging arms, the heavy objects can be carried quickly in order, and the operation efficiency is greatly improved. A motor in the hoisting equipment is directly controlled by a program module, remote control can be achieved, and the functions of non-load traveling, on-load rotation, hoisting and the like of the whole hoisting equipment are completed efficiently and accurately.
Description
technical field [0001] The invention belongs to the field of small and medium-sized tonnage lifting operations, and discloses a double-swing arm type lifting device, in particular, a lifting device with symmetrical ends and simultaneous lifting and placement of multiple objects. Background technique [0002] Hoisting machinery is an important auxiliary machinery in heavy lifting, transportation and other operations, which can reduce the physical labor of workers and improve work efficiency. At present, in construction sites and factory buildings, large-scale cargo transportation and hoisting are completed by large gantry and bridge cranes. However, gantry and bridge cranes are mostly limited by space and can only play a role in specific situations. For small and medium-sized goods in factory warehouses, wharf loading and unloading and railway road maintenance, forklifts or manual handling are often used, which increases the output of manual labor, and the efficiency is very ...
