It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

Referring to fig. 1, 2, 3, 4 and 5, a safe KBK manual trolley includes a frame 2 with rollers 1, support plates 3 are installed at two ends of the frame 2, a limit plate 4 is installed between the support plates 3, a horizontal rotating wheel 5 is installed on a top surface of the limit plate 4, a diameter of the horizontal rotating wheel 5 is larger than a thickness of the limit plate 4, the limit plate 4 and the support plates 3 are integrally formed, a moving channel 16 penetrating downwards is installed in the support plates 3, a limit block 17 is installed on a side wall of a port of the moving channel 16, a damping plate 19 with a resisting block 18 is installed in the moving channel 16 in a sliding manner, the resisting block 18 is in sliding fit with an inner wall of the moving channel 16, the resisting block 18 is prevented from coming out of the moving channel 16 by cooperation of the resisting block 18 and the limit block 17, and a plurality of damping plates 19 are installed between a top surface of the damping plate 19 and the inner wall of the moving channel 16 and are always in a Damping spring 20, when the bottom of shock attenuation board 19 is not atress, aforementioned damping spring 20 stretches out shock attenuation board 19 all the time and lets aforementioned stop block 18 and stopper 17 laminate all the time, the distance of the bottom of shock attenuation board 19 apart from the installation slide rail is greater than the distance of gyro wheel 1 apart from the installation slide rail.

In the embodiment, when the manual trolley normally runs, the roller 1 is embedded in the roller, the bottom end of the roller 1 is in contact with the roller 1, the limiting plate 4 is vertically parallel to the inner wall of the track, the supporting plate 3 plays a supporting role for the limiting plate 4 in the normal running process of the trolley, and the side surface of the horizontal rotating wheel 5 rotatably installed on the top surface of the limiting plate 4 is in sliding contact with the inner wall of the track, so that in the normal running process of the trolley, the rolling friction between the horizontal rotating wheel 5 and the inner wall of the track replaces the sliding friction between the limiting plate 4 and the inner wall of the slide rail, so that the trolley can be more stably installed in the slide rail under the action of the horizontal rotating wheel 5 on the limiting plate 4, and meanwhile, the; when the wheel axle of the trolley is broken, the trolley falls, when the trolley falls to the position of the damping plate 19, the bottom surface of the damping plate 19 is in contact with the inner wall of the track, the damping spring 20 is compressed to buffer the impact generated between the trolley and the slide rail in the falling process, the damage to the inner wall of the slide rail and the trolley caused by the hard collision is reduced, compared with the limiting plate 4 and the supporting plate 3 which are in direct hard contact with the slide rail, after the damping spring 20 buffers, the kinetic energy variation of the trolley is the same, namely the impulse is the same, and the damping spring effectively increases the action time of force, so that the stress of the limiting plate 4 and the supporting plate 3 is relatively smaller, the service lives of the limiting plate 4 and the supporting plate 3 can be effectively prolonged, the safety protection of the limiting plate 4 and the supporting plate 3 to the trolley is more stable and effective, the damping plate 19, and, this moment because the shaft has already fractured, the gyro wheel 1 of dolly can not rotate again, and the dolly also can not remove once more, and the staff also can know like this, and the dolly has appeared the problem, needs to change the dolly. The safety accident or economic loss caused by the fact that the trolley falls off from the track due to the fact that the axle of the trolley is broken is effectively avoided.

Example 2

On the basis of the embodiment 1, at least two pairs of coaxially mounted rollers 1 are mounted on the frame 2, the coaxially mounted rollers 1 are symmetrically mounted on two sides of the frame 2, and two adjacent pairs of rollers 1 are arranged on the same plane, so that certain stability can be kept in the process that the whole manual trolley moves in the sliding rail.

Simultaneously in this embodiment, on the same side of frame 2, all gyro wheels all set up between two backup pads 3, let limiting plate 4 all cover with frame 2 gyro wheel 1 of the same side promptly.

Example 3

On the basis of embodiment 2, the roller 1 is installed on the frame 2 through a wheel shaft 6, a bearing 7 and the roller 1 are sequentially sleeved at two ends of the wheel shaft 6 from inside to outside, a shaft clamp spring 8 for fixing is further installed at the end of the wheel shaft 6, and the purposes of removing the roller 1 and replacing the wheel shaft 6 can be achieved by detaching the shaft clamp spring 8.

Example 4

In embodiment 3, a pair of reinforcing plates 9 are mounted on the bottom side of the frame 2, and a pin 11 is mounted between the reinforcing plates 9 via an anti-slip clip 10.

Example 5
