The universal wheels are arranged at the bottom of the frame body 10, so that the frame body 10 can be moved conveniently.

A bearing frame body 20 is arranged between the two vertical frames 11, and the bearing frame body 20 is used for bearing the material box. In order to realize that the bearing frame body 20 can move up and down in the rack body 10, a slide rail 21 is arranged on one of the stands 11 along the moving direction of the bearing frame body 20, and a slide block is fixedly arranged at the side edge of the bearing frame body 20 and is slidably arranged on the slide rail 21, and the slide block and the slide rail 21 have the function of guiding the bearing frame body 20 to move.

When the material box needs to be dragged to a table top with a certain height, the bearing frame body 20 is lifted to the height of the level table top or the table top, and the material box is dragged to the table top, so that the purpose of moving the material is achieved. In order to provide tension support for the load-bearing frame 20 in the raised state, a lifting rope assembly having a tail end suspended on the load-bearing frame 20 is disposed on the frame body 10, and the lifting rope assembly includes a flexible rope having two ends respectively fixed to the vertical frame 11 and the side edge of the load-bearing frame 20, and a pulley 31 for winding the flexible rope and having a height not lower than the upper limit of the lifting of the load-bearing frame 20.

Specifically, a pulley 31 is fixed to the upper end of the two vertical frames 11, a guide wheel 35 is fixed to the bottom of the two vertical frames 11, and the installation height of the pulley 31 is the height of the upper lifting limit of the bearing frame 20. One end of the flexible cable is fixed at the bottom of the first vertical frame 11, and the other end of the flexible cable extends upwards to the pulley 31 at the upper end of the second vertical frame 11 by passing through the guide pulley 35 at the bottom of the second vertical frame 11, and finally is fixed at the side of the bearing frame 20 by passing through the pulley 31 at the upper end of the second vertical frame 11. Correspondingly, four groups of hoisting rope assemblies wound in the way are symmetrically arranged on the two stands 11 respectively. The pulley 31 and the guide wheel 35 are disposed on a slide rail seat fixed on the stand 11, and the pulley 31 and the guide wheel 35 can move along the slide rail direction of the slide rail seat to adjust the fixed position, thereby adjusting the balance of the flexible cable.

The two sides of the bearing frame body 20 are pulled by four groups of flexible cables, and the tensile force is provided to maintain the ascending or descending state of the bearing frame body 20. To improve the stability of the cable tensile load frame 20, the present embodiment provides a cable composed of a lift cable 33 and an elastic cable 34. The lifting rope 33 has small elasticity and poor tensile property; the elastic cord 34 is strong in elongation and good in elasticity.

One ends of the lifting rope 33 and the elastic rope 34 are fixed on the connecting rod 32, the connecting rod 32 is positioned between the pulley 31 and the guide wheel 35, the other end of the lifting rope 33 is fixed on the side of the bearing frame body 20 by passing through the pulley 31 at the upper end of the vertical frame 11, and the other end of the elastic rope 34 is fixed on the bottom of the other vertical frame 11 by passing through the guide wheel 35 at the lower end of the vertical frame 11.

Connected to and pulling the carrying frame is a lifting cable 33, which lifting cable 33 has a low tensile strength ensuring a good stability when pulling up the carrying frame 20. Connected and fixed to the stand 11 is a spring wire 34, and the spring wire 34 has a long length and provides a displacement of tensile deformation for the ascending or descending movement of the carriage body 20. When the bearing frame body 20 is positioned at the lower part, the elastic ropes 34 are in a stretching and tightening state; when the load frame 20 is positioned upward, the spring cable 34 is in a relaxed state.

In order to make the carriage 20 stop at any height, a positioning assembly for clamping the carriage 20 is provided on the frame body 10.

When the vertical shaft 41 is arranged perpendicular to the bottom surface, the friction force between the high-strength rubber ring 42 and the vertical shaft 41 is small, and the height of the bearing frame 20 can be easily changed by pressing or lifting the bearing frame 20. When the vertical shaft 41 is arranged at a certain included angle in the vertical direction, a large friction force exists between the high-force rubber ring 42 and the vertical shaft 41, the magnitude of the friction force is in direct proportion to the magnitude of the included angle, and the larger the included angle is, the larger the friction force is.

When the weight of the bearing frame body 20 is larger than the tensile force of the elastic cable 34, the friction force of the vertical shaft 41 on the high-force rubber ring 42 is upward, and the bearing frame body 20 is prevented from descending; when the load-bearing frame 20 is empty or has little material, the tension of the elastic cable 34 is larger than the weight of the material, the friction force of the vertical shaft 41 on the high-force rubber ring 42 is downward, and the friction force counteracts the tension of the elastic cable 34 at the moment, so that the load-bearing frame 20 is prevented from rising. Therefore, the stagnation state of the bearing frame body 20 can be realized by adjusting the included angle between the vertical shaft 41 and the gravitational rubber ring 42, the bearing frame body 20 can be positioned at any height, and the purpose of material flowing is realized corresponding to the working tables or the butt joint clamping plates with different heights.
