The working principle is as follows: clamp plate 212 and channel-section steel 7 contact, when freight on to platform 8, the goods pushes down platform 8 and channel-section steel 7, make the channel-section steel 7 crooked that stretches out lower floor 1, because leverage, the channel-section steel 7 part tilt up that is located lower floor 1 upper end, channel-section steel 7 produces ascending power to clamp plate 212, its pressure value is sensed to two 213 pressure sensors, two 213 of pressure sensors give the controller with signal transmission, the controller gives pressure display 216 with pressure value signal transmission, pressure display 216 shows this pressure value in real time, and simultaneously, a controller command signal lamp 214 is bright.
When the second pressure sensor 213 senses that the pressure reaches a set value, the first signal lamp 214 is turned off, the second signal lamp 215 is turned on, the controller commands the electromagnetic plate 211 to be powered off, the electromagnetic plate 211 does not press the moving rod 209 upwards together with the channel steel 7 any more, the moving rod 209 moves along the third sliding groove 205, the first spring 208 is pressed by the annular iron plate 210 on the moving rod 209, and the first spring 208 presses the annular mounting plate 206. After the pressure sensor I207 in the annular mounting plate 206 senses the pressure value, the signal is transmitted to the controller, the controller transmits the pressure value signal to the pressure display 216, and the pressure display 216 displays the pressure value of the pressure sensor I207 in real time.
When the channel steel 7 deforms too much, the moving rod 209 and the pressing plate 212 are completely extruded into the third sliding groove 205 by the channel steel 7, at the moment, the sliding rod 202 is continuously extruded upwards by the channel steel 7, the sliding rod 202 moves upwards along the fourth sliding groove 224, the fixed plate 220 is extruded by the pressing rod 219, the third pressure sensor 221 in the fixed plate 220 senses a pressure value, a signal is transmitted to the controller, the controller instructs the second signal lamp 215 to go out, and meanwhile, the third signal lamp 222 and the alarm 223 work to remind constructors that the goods on the platform 8 are overweight in time. The pressure that produces according to the different deformation of channel-section steel 7 is divided into three pressure value sections, utilizes signal lamp one 214, signal lamp two 215, signal lamp three 222 to remind constructor, makes things convenient for constructor to acquire the goods overload condition fast.
When the slide bar 202 presses the mounting plate upward, the mounting plate drives the first rotating plate 404 to rotate, so that the first rotating plate 404 rotates downward against one end of the second rotating plate 406. When the first rotating plate 404 rotates, the sliding rod 409 drives the second rotating plate 406 to rotate, so that one end of the second rotating plate 406, which is close to the first rotating plate 404, rotates downwards, and one end of the second rotating plate 406, which is far from the first rotating plate 404, rotates upwards.

One end of the transition plate 602, which is far away from the transfer plate 601, is hinged with two traction blocks 603, and traction holes 604 are arranged on the traction blocks 603. Platform 8 is embedded to have auxiliary roller 605, and carry over pinch rolls 606 is installed to 1 upper end of lower floor and the one end that is located platform 8, and carry over pinch rolls 606 is rotated by the motor drive. Two groups of traction mechanisms are fixed at the upper end of the lower floor slab 1, each traction mechanism comprises a third spring 607 and a traction hook 608, one end, far away from the platform 8, of the third spring 607 is fixed with the lower floor slab 1, and the other end of the third spring 607 is fixed with the traction hook 608.
The working principle is as follows: when the goods are carried, the transition plate 602 may be rotated such that the transition plate 602 is in contact with the lower floor 1, thereby facilitating the carrying of the goods. When the alarm 223 rings, the platform 8 overloads, and constructors are difficult to walk to the platform 8 to remove goods, hook the towing hook 608 on the towing hole 604, pull the fixed plate 220 and the transfer plate 601, and can save labor to remove the transfer plate from the platform 8 through the assistance of the towing roller 606 and the auxiliary roller 605, thereby preventing the constructors from accidents.
The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the present invention as defined in the accompanying claims.
