In the figure: the device comprises a mounting plate foundation 1, a cover plate 2, a folding protection rod 3, an electric push rod 4, a mounting bracket 5, a rotating shaft 6, a bearing seat 7, a retainer ring 8, a trapezoid frame 3.1, a stop lever 3.2, a push rod 3.3 and a retraction spring piece 3.4.
Detailed Description
As shown in fig. 1, a safe and labor-saving lifting hole cover plate comprises a mounting plate foundation 1, wherein the mounting plate foundation 1 is fixed on the existing lifting hole foundation. The mounting plate foundation 1 is provided with a cover plate 2 from left to right, the lower end of the cover plate 2 is provided with a rotating shaft 6, the rotating shaft 6 is mounted on a bearing seat 7 of the mounting plate foundation 1 through a bearing, the bearing seat 7 is fixed on a fixed plate of the mounting plate foundation 1 through bolts, and the left end and the right end of the rotating shaft 6 are positioned through check rings 8. The two cover plates 2 are rotatable structures, and form guardrails on the front side and the rear side when being opened, and the two cover plates 2 can be closed to the hanging holes after being closed. The folding guard bar 3 is arranged in front of and behind the mounting plate foundation 1, the folding guard bar 3 is driven by the electric push bar 4 to lift up and down, and the electric push bar 4 is fixed on the mounting bracket 5. When the folding guard bar 3 rises, the cover plates 2 on the left and right can be gradually jacked up by the folding guard bar 3, and the guard bars can be formed with the two cover plates 2 on the left and right after the front and rear folding guard bar 3 rises to the upper limit position, so that the hoisting safety is ensured. When the folding guard bar 3 is lowered to the lower limit position, the cover plate 2 is closed and supported by the folding guard bar 3.
The folding protection rod 3 comprises a trapezoid frame 3.1, and the trapezoid frame 3.1 can gradually jack the cover plate 2 open when ascending, so that stability is guaranteed. The inner side of the trapezoid frame 3.1 is provided with a stop lever 3.2, and the stop lever 3.2 and the trapezoid frame 3.1 form a guardrail. The left and right sides of the outer side of the upper end of the trapezoid frame 3.1 are hinged with ejector rods 3.3, and the ejector rods 3.3 are ejected through a lower retracting spring piece 3.4. After the folding guard bar 3 rises to the upper limit position, the ejector rod 3.3 can be propped against the cover plate 2, so that the cover plate 2 is stably kept vertical and does not swing.
The electric push rod 4 in the device is connected with an external power supply, and the electric push rod 4 is controlled to lift through a button on a control box.
Working principle and process: when the folding type protective rod 3 moves upwards, the cover plate 2 can be gradually opened by the folding type protective rod 3 in a gradual change mode; along with the opening of the cover plate 2, the ejector rod 3.3 gradually rotates outwards from an inwards folded state under the action of the retracting elastic sheet 3.4; when the cover plate 2 rotates to a vertical state, the upper end of the cover plate 2 is tightly propped up by the ejector rod 3.3.
