The trackless electric flat carriage is a convenient and flexible short-distance carrying tool, has the characteristics of simple structure, convenient use, large bearing capacity, dirt resistance, smashing resistance, easy maintenance, long service life and the like, becomes a preferred transport tool for frequently carrying heavy objects at short distance fixed points inside an enterprise factory building and between the factory building and the factory building due to the advantages of convenience, strong practicability, easy cleaning and the like, and is widely used in industrial production.
The trackless electric flat carriage of prior art has certain drawback mostly in use, most electric flat carriages do not set up clamping mechanism, can not carry out the screens to the circular easy rolling goods and materials such as loading cable drum, thereby make article landing from it easily, make the article that easily rolls often can't place on electric flat carriage, lead to unable transportation, the stationarity to circular object transport has been reduced, and simultaneously, the goods that load at trackless electric flat carriage operation in-process rocks and to have the harm to influence life to the damping performance of car. In addition, a small part of electric flat carriage in the prior art is provided with a clamping mechanism, for example, patent CN110861563A discloses an electric flat carriage with a V-shaped frame, but the V-shaped frame is fixedly mounted on the electric flat carriage, so that only circular easily-rolling materials of a certain size can be transported, and the transportation of circular materials of various specifications cannot be realized, so that the flexibility is low, and various transportation requirements in industrial production cannot be met. And the screens mechanism anchor clamps of patent CN110861563A are vertical nonadjustable V type structure, and the clamping direction of anchor clamps is perpendicular with the automobile body direction of advancing, and because of the manufacturing deviation of the goods and materials that carry, its actual width will be little than standard design size, and at this moment when electric flat car emergency brake, the frictional force of both sides will be not enough to hold tightly the goods and materials to make the goods and materials slide out injure personnel or equipment from the front because of stronger inertia, therefore this design has serious potential safety hazard.
In addition, in the aspect of safety, the existing electric flat carriage generally adopts manual work to realize the braking of a carriage body through remote control, or adds audible and visual alarm to achieve the purpose of warning on the basis, but as the factory operation site is often noisy, the alarm sounds of various machines are mixed, personnel can not accurately identify the alarm source, so that the personnel mistakenly enter the operation section of the flat carriage, the goods and materials carried by the electric flat carriage are generally higher and wider, the operators generally remotely control from the side, and at the moment, a single operator has a visual field blind area, is difficult to find other personnel entering the operation section in time and applies the braking, and serious production accidents can be caused.
