[0002] In production and life, tanks are often needed to store and react materials. Tanks are generally used in conjunction with covers. When it is necessary to take out materials from the tank or observe the situation inside the tank, the cover needs to be opened. Since the cover has a certain weight, the cover is currently basically opened by driving the cover up and down with a cylinder. With the development of technology, the concept of "safety first" has become a consensus among people. The design, manufacturing and use units of industrial equipment, any operation of a moving device may cause an accident due to loss of control. The currently used method of driving the cover up and down by a cylinder does not set other protective devices. Therefore, the cover only moves up and down through the power of the cylinder.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0020] like Figures 1 to 6The safety device of a lifting cover shown in the figure comprises a mounting frame 1 and a latch 11, the mounting frame 1 is connected to a tank body 2, the tank body 2 is connected to a cover body 3, a connecting plate 7 is connected to the right side of the cover body 3, the tank body 2 is connected to a fixing plate 4, the fixing plate 4 is connected to a cylinder 5, the output shaft of the cylinder 5 is connected to the connecting plate 7, the fixing plate 4 is connected to a steel groove column 6, the cross section of the steel groove column 6 is an I-shaped, the steel groove column 6 is connected to a positioning plate 9 by bolts, the connecting plate 7 is connected to a support plate 10, the support plate 10 and the positioning plate 9 are respectively provided with a support hole 14 and a positioning hole 13, the latch 11 is connected to the support plate 10, the support plate 10 and the positioning plate 9 are respectively provided with a support hole 14 and a positioning hole 13, and the latch 11 is connected to the support plate 10. The pin 11 cooperates with the supporting hole 14 and the positioning hole 13. The diameter of the pin 11 is the same as the diameter of the supporting hole 14 and the positioning hole 13. The pin 11 is threadedly connected with the positioning nut 12. The connecting plate 7 is connected with the slider 8. The slider 8 is slidingly connected with the steel channel column 6. The pin 11 is connected with a holding ring 15. The side of the pin 11 away from the holding ring 15 is truncated in a cone shape to facilitate the pin 11 to pass through the supporting hole 14 and the positioning hole 13. A hook 17 is connected to the lower side of the steel channel column 6. The support plate 10 is connected with a reinforcing plate 16, and the reinforcing plate 16 is connected to the connecting plate 7.

[0021] The specific implementation process is as follows:

[0022] When the cover 3 and the tank body 2 are buckled, the latch 11 is hung on the hook 17 through the holding ring 15. When the cover 3 is opened, the buckle of the cover 3 and the tank body 2 is released, and then the connecting plate 7 is driven upward by the cylinder 5, and then the cover 3 and the support plate 10 are driven upward. The cooperation of the slider 8 and the steel channel column 6 enables the cover 3 to move upward stably. When the cover 3 moves up to a suitable height, the support hole 14 is flush with the positioning hole 13. At this time, the latch 11 is removed, and the latch 11 is inserted into the support hole 14 and the positioning hole 13 from right to left in turn, and then the positioning nut 12 is screwed on to complete the limiting of the support plate 10 and the positioning plate 9. Figure 1 and Figure 2 As shown, the support plate 10 and the positioning plate 9 form a relatively fixed whole through the latch 11, thereby playing a pulling and supporting role for the cover body 3. In this way, even if the cylinder 5 loses the air source, the positioning plate 9 and the steel channel column 6 will pull the support plate 10, the connecting plate 7 and the cover body 3 through the latch 11 to prevent the cover body 3 from sliding down, thereby ensuring the stability of the cover body 3.

[0023] The technical solution further limits the cover body 3 through the cooperation of the steel channel column 6, the support plate 10, the positioning plate 9 and the latch 11, so that the cover body 3 will not easily slide down when the cylinder 5 loses the gas source, which greatly improves the stability of the cover body 3 and ensures the safety of the operator; the limit and release of the cover plate can be completed by plugging and pulling out the latch 11, the structure is simple and the operation is convenient; a slider 8 is provided, and the slider 8 is limited by the steel channel column 6, so that the slider 8 and the cover body 3 can only move vertically up and down, further improving the stability of the movement of the cover body 3; the holding ring 15 is convenient for the staff to hold the latch 11, and the force is convenient. The latch 11 can be hung on the steel channel column 6 by the hook 17 and the holding ring 15, which is convenient for the operator to take samples at any time, convenient for storage, and improves the convenience of operation; the supporting capacity of the support plate 10 is improved by the reinforcing plate 16, so that the strength of the support plate 10 is sufficient to bear the weight of the cover without deformation.
