Compared with the traditional overhanging type discharging platform, the overhanging type discharging platform has the advantages of less occupied materials, less labor consumption, no influence on the engineering construction progress and good construction site image. The biggest potential safety hazard of the lifting type discharging platform is the falling problem of the discharging platform, and the traditional anti-falling measures have simple and crude structure and slow response and are frequently failed and invalid.
The invention content is as follows:
an object of the utility model is to provide an over-and-under type platform anti-falling device of unloading to reach effectual unexpected implementation protection, sensitive, the safe and reliable's of reaction of falling of platform of unloading.
The utility model provides a lifting type unloading platform anti-falling device, which is characterized by comprising a wall-attached support, wherein the wall-attached support comprises a flange edge and a mounting plate, and the flange edge is fixedly connected with the mounting plate; the flange edge is provided with a through hole and is arranged on the wall through a bolt; the mounting plate is provided with a fixed shaft and an anti-falling stop lever; the linkage swing block, the anti-falling swing block and the torsion spring are arranged on the fixed shaft and are connected through the torsion spring; one end of the tension spring is fixed on the mounting plate, and the other end of the tension spring is connected with the anti-falling swing block; the position of the anti-falling swing block corresponds to the position of the anti-falling stop lever; the supporting blocks are uniformly arranged on the lifting type discharging platform, and the positions of the linkage swinging block and the anti-falling swinging block correspond to the positions of the supporting blocks.
Furthermore, the tension spring is fixed on the mounting plate through a bolt.
Furthermore, the supporting block is arranged on a guide rail of the lifting type discharging platform.
Furthermore, the flange edge and the mounting plate are welded and fixed.
Furthermore, the mounting panel on set up the protecting crust, the linkage pendulum piece, prevent weighing down pendulum piece, torsional spring, extension spring all set up in the protecting crust.
Furthermore, the flange edge and the mounting plate are vertically and fixedly connected.
The utility model provides a lifting type unloading platform anti-falling device, which is designed by utilizing the differential principle, and has simple structure and sensitive reaction; important parts are arranged in the protective shell, so that the protective shell can adapt to severe working environment and has long service life; effectively preventing the falling of the lifting type discharging platform.
Description of the drawings:
the invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic view of the anti-falling operation of the utility model.
The specific implementation mode is as follows:
the anti-falling device of the lifting type unloading platform shown in the figure 1-2 is characterized in that a flange edge 1-1 and a mounting plate 1-2 are cut by laser according to a drawing; vertically and fixedly welding the flange edge and the mounting plate together to form a wall-attached support 1; the wall-attached support comprises a flange, a mounting plate, a fixed shaft 3 and an anti-falling stop lever 4, wherein the mounting plate is riveted with the flange, an anti-falling swinging block 6, a torsion spring 7 and a linkage swinging block 5 are sequentially mounted on the fixed shaft, and the linkage swinging block and the anti-falling swinging block are supported and connected through the torsion spring; one end of a tension spring 8 is fixed on a reserved hole of the mounting plate through a bolt, and the other end of the tension spring is connected with a reserved hole of the anti-falling swing block; the position of the anti-falling swing block corresponds to the position of the anti-falling stop lever; the supporting blocks 9 are uniformly arranged on the lifting type discharging platform 10 through welding, and the positions of the linkage swinging block and the anti-falling swinging block correspond to the positions of the supporting blocks.
When the lifting type unloading platform rises, the supporting block 9 pulls the linkage swing block 5 upwards, the linkage swing block 5 does reciprocating motion under the action of the torsion spring, and the lifting type unloading platform continuously rises.
When the lifting type unloading platform normally descends, the lower supporting block 9 stirs the linkage swing block 5, and the linkage swing block 5 drives the anti-falling swing block 6 to rotate through the torsion spring. The end part of the anti-falling swing block 6 is positioned below the upper supporting block 9; the lifting type discharging platform continues to descend, the lower supporting block 9 passes through the linkage swinging block 5, the linkage swinging block 5 is not stressed by the force of the lower supporting block 9 any more, the linkage swinging block 5 and the anti-falling swinging block 6 reset under the action of the tension spring, and the upper supporting block 9 shifts the linkage swinging block 5 again through the anti-falling swinging block 6; the actions are continuously carried out, and the lifting type unloading platform normally descends.
When falling occurs, the linkage swing block 5 is pulled by the lower supporting block 9, and the linkage swing block 5 drives the falling prevention swing block 6 to rotate through the torsion spring. The end part of the anti-falling swing block 6 is positioned below the upper supporting block 9; because the speed is very fast, the anti-falling swing block cannot be reset in time, the upper supporting block 9 presses the end part of the anti-falling swing block 6, the tail end of the anti-falling swing block 6 is blocked by the anti-falling stop lever 4, and the lifting type discharging platform is blocked at the moment to prevent continuous falling and avoid accidents.
