Description

Technical Field

[0001] This utility model relates to the field of trolley technology, specifically a boom lifting trolley. Background Technology

[0002] In fields such as industrial production, equipment maintenance, warehousing and logistics, and construction, it is often necessary to transfer, lift, position, or assemble small and medium-sized parts, tools, or materials over short distances. Manual handling is not only labor-intensive and inefficient, but also poses safety hazards when handling heavy or large objects.

[0003] The current trolleys only have simple carrying and moving functions, and cannot achieve vertical lifting of materials. They require manual loading and unloading and are powerless for operations that require positioning and installation at high altitudes. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a boom lifting platform.

A bearing is embedded in the top of the support plate, and a platform is mounted on the top of the support plate. A bearing is sleeved on the bottom of the platform, and the bottom of the platform is rotatably connected to the support plate via the bearing. A support beam is vertically fixedly connected to the middle of the front side of the top of the trolley, and a crossbeam is fixedly connected to the top of the support beam. The crossbeam extends rearward, and a groove plate is fixedly connected to the bottom of the crossbeam. Sliding holes are provided on the right side and bottom of the groove plate. Two racks are fixedly connected to the inner bottom of the groove plate, located on the left and right sides of the sliding holes at the bottom of the groove plate, respectively. A winch is mounted at the bottom of the groove plate, and a protrusion is fixedly connected to the top of the winch. A sliding hole runs through the bottom of the slotted plate. There is a gap between the protrusion and the sliding hole. The front and rear ends of the protrusion are rotatably connected to a rotating shaft. The rotating shaft extends to the left and right. Two gears are fixedly sleeved on the outer walls of the left and right ends of the rotating shaft. The two gears mesh with two racks at the bottom. The right end of the rear rotating shaft extends to the right and passes through the sliding hole on the right side. There is a gap between the right end of the rear rotating shaft and the sliding hole on the right side. A mounting frame is fixedly connected to the right side of the outer wall of the winch. A motor and a reduction gearbox are installed on the mounting frame. The output shaft of the motor is connected to the input shaft of the reduction gearbox. The output shaft of the reduction gearbox is fixedly connected to the right end of the rear rotating shaft. The winch has a wire rope that hangs downward. A hook is fixedly connected to the lower end of the wire rope. A hanger is hung on the hook. Three chains are installed on the hanger. A hook is fixedly connected to the end of each chain.

[0007] A fixing plate is fixedly connected to the left side of the outer wall of the winch. The fixing plate and the mounting frame are symmetrically distributed on the left and right sides, and a counterweight is set on the top of the fixing plate.

[0008] Fixed blocks are fixedly connected to the front and rear ends of the right side wall of the crossbeam. A sliding rod is fixedly connected between two fixed blocks. Several sliders are set on the sliding rod. The sliders slide in cooperation with the sliding rod. Battery boxes are set on the left and right sides of the top front of the trolley. Wires are connected between the battery boxes and the motor. The wires pass through several sliders and are snapped into the sliders. One end of the wire is electrically connected to the battery box and the other end of the wire is electrically connected to the motor. The foremost slider is fixed to the front end of the sliding rod and is close to the front fixed block.

[0009] A storage box is installed on the rear top of the trolley.

[0010] The trolley includes three square rods: square rod one, square rod two, and square rod three. Square rod one and square rod two are arranged in parallel. One end of square rod one and square rod two is equipped with a caster wheel, and the other end of square rod one and square rod two is equipped with a fixed pulley wheel. The bottom of the support beam is vertically fixed to the upper midpoint of square rod three. A support plate is fixedly connected between the upper parts of square rod one and square rod two. The bottom of the column is vertically fixedly connected to the center of the upper part of the support plate. The bottom ends of the box are fixed to the upper parts of square rod one and square rod two, respectively.

[0011] The beneficial effects of this utility model are:

[0012] The winch is driven by a motor to move horizontally, and the winch drives the lifting frame to lift vertically, so as to achieve precise adjustment of the position of the object. This solves the problem of inconvenient lifting of traditional trolleys and realizes integrated operation of movement, lifting and hoisting. It has the advantages of flexibility, stability and practicality, and effectively solves the problems of single function and low handling efficiency of traditional trolleys.
