Problems solved by technology

Crawler cranes are suitable for rough and uneven sites, but their driving speed is slow, and the road surface is seriously damaged during driving, so special vehicles must be used for transportation when transferring
At the same time, the tracked chassis is heavy and expensive to manufacture

Embodiment Construction

[0028] The invention realizes the high-efficiency and flexible lifting functions of the crane through the design of the three-part system of movement, lifting and clamping. Relying on mecanum wheels and four-wheel drive to realize the movement of the whole vehicle. The two sets of lifting systems installed at the front and rear of the vehicle use the slider screw mechanism to realize the lifting action. The rack and pinion mechanism is used to realize the opening and closing of the hand grip, and complete the grabbing action of the goods. The control signal is given through the switch and rocker of the remote controller to realize the control of the crane.

[0029] mechanical parts, such as Figure 1 to Figure 4 shown.

[0030] control part, such as Figure 5 control system shown.

[0031] Relying on the STM32F407 chip of STMicroelectronics and the FLYSKY aircraft model remote control, the corresponding remote control of the actions of various parts of the mechanism is re...

Abstract

The invention provides a light carrying trolley, and relates to a novel hoisting scheme of a crane. The light carrying trolley is suitable for conducting efficient lifting and obstacle avoidance carrying on heavy objects under complex working environments and conditions; the functions of high efficiency and flexible lifting of the crane are achieved mainly through the system design of the three parts of movement, lifting and clamping; the whole trolley moves through Mecanum wheels and four-wheel drives, and the efficiency is doubled through two sets of lifting systems arranged at a headstock and a tailstock; the lifting action is achieved through a sliding block and lead screw mechanism, and during working, a motor can be self-locked; a grip is opened and closed through a gear and rack mechanism, and thus goods are grabbed; the grip is extended to a certain extent in the longitudinal direction, the tail end is collected to a certain extent, and thus clamping stability and safety are ensured; and as for control, actions of all parts of the mechanisms are remotely controlled correspondingly through an STM32F407 chip of ST Microelectronics and a FLYSKY model airplane remote controller.

Description

technical field [0001] The invention relates to a crane, in particular to a light transport trolley. Background technique [0002] Cranes are widely used in various engineering constructions such as industrial buildings, civil buildings, and industrial equipment, and undertake the main tasks of transportation, loading, unloading, and installation. It plays an important role in reducing the intensity of manual labor, reducing construction costs, improving construction efficiency, and improving construction quality. There are many types of cranes, and the main types commonly used are: tire cranes (truck cranes, tire cranes), tower cranes, crawler cranes, etc. The rubber-tyred crane has a high speed and can be transferred quickly, but limited by the chassis, the body is longer and the turning radius is larger. Tower cranes have high requirements on the site. They usually walk on special wide tracks, which require a flat site to lay the tracks, which increases the cost of layi...
