Referring to fig. 1-4, a detachable stop device of a belt conveyor comprises a main guard plate 1, wherein lifting lugs 2 are arranged on the main guard plate 1; in this embodiment, the lifting lugs 2 are fixed by being hung on an external beam. A shielding mechanism 3 is arranged below the main guard plate 1; the guard mechanism 3 includes: the auxiliary guard board 301, two ends of the auxiliary guard board 301 are connected with the main guard board 1 through bolts 7, and the middle part of the auxiliary guard board 301 is tightly attached to the main guard board 1; the lower part of the auxiliary guard board 301 is provided with a guard 302. In this embodiment, the main guard plate 1 is provided with a leakage-proof positioning groove 6 matched with the auxiliary guard plate 301, and the upper edge of the auxiliary guard plate 301 is inserted into the leakage-proof positioning groove 6 to prevent the auxiliary guard plate 301 from being attached to the main guard plate 1 in a loose manner, and a gap exists to cause leakage.

In this embodiment, the main guard plate 1 is provided with positioning holes 4, and the auxiliary guard plate 301 is provided with positioning pins 5 corresponding to the positioning holes; the positioning pins 5 on the subsidiary guard 301 are inserted into the positioning holes 4 on the main guard 1 for accurate positioning.

In this embodiment, the sheath 302 is a cloth-sandwiched rubber.

In this embodiment, two ends of the auxiliary guard 301 are screwed to the main guard 1 by two bolts 7.

In this embodiment, the weight of the sub-shield 301 is smaller than the weight of the main shield 1.

In this embodiment, the groove depth of the leak-proof positioning groove 6 is greater than 30 mm.

The utility model has the following beneficial effects: the device has simple structure and convenient operation; according to the device, the original material blocking device is split into the structure of the protective cover 302 of the main protective plate 301 and the auxiliary protective plate 301, the leakage-proof positioning grooves 6 and the positioning pins 5 are additionally arranged between the main protective plate 301 and the auxiliary protective plate 301, and the two ends outside the limited area are connected through threads, so that when the protective cover 302 is replaced originally, maintenance personnel are required to enter a limited space and difficultly disassemble the connecting bolts 7, more than 8 persons are required to drag the heavy protective plate protective cover 302 out of the belt conveyor, more than 8 persons are required to send the protective plate protective cover 302 into the belt conveyor after the protective cover 302 is replaced, the bolts 7 are installed in the limited space, and the problems that the maintenance personnel are very difficult to finish the maintenance in the limited space are solved; the original structured guard 302 guard plate needs maintenance personnel to enter a limited space, and is not needed at present; the original structure of the sheath 302 needs 8 people for 4 hours, and only 2-3 people need 1 hour at present; when the original structural sheath 302 is replaced, the device for integrally disassembling the protective plate sheath 302 is not needed, and the working efficiency is greatly improved.

The material blocking device guard plates are made into a detachable main guard plate 1 and an auxiliary guard plate 301, the main guard plate 11 is formed by reducing the width of the original guard plate according to the requirement, and the connection mode of the original guard plate and the cross beam is unchanged. The secondary shield 301 is made from 100 x 10 flat steel. The auxiliary guard 301 is provided with a hole for making a bolt 7 and is connected with the guard 302 by using the bolt 7. In order to prevent gap leakage of the main guard plates 301, the main guard plates 1 are provided with leakage-proof positioning grooves 6, and the leakage-proof positioning grooves 6 can prevent gap leakage between the main guard plates 301 and the auxiliary guard plates 301 from being deformed due to blanking, and can limit the transverse freedom degree of the auxiliary guard plates 301 along the belt conveyor. The middle position of the main guard plate 1 is provided with a positioning hole 4, the middle position of the auxiliary guard plate 301 is provided with positioning pins 5, and the two ends of the main guard plate 1 and the two ends of the auxiliary guard plate 301 are respectively provided with a bolt 7 and a bolt 7 hole correspondingly for connecting the main guard plate 1 and the auxiliary guard plate 301. The positioning holes 4, the positioning pins 5 and the bolts 7 at the ends of the main guard plate 301 are connected, so that the auxiliary guard plate 301 is positioned along the longitudinal direction of the belt conveyor.

When the sheath 302 is replaced, maintenance personnel do not need to enter a limited space to remove the bolts 7, only need to remove the connecting bolts 7 at two ends of the main guard plate 1 and the auxiliary guard plate 301 (the bolts 7 are arranged outside the end part of the beam and are not in the limited space), slightly lift the lower end of the auxiliary guard plate 301, enable the positioning pins 5 to be separated from the positioning holes 4, and enable the auxiliary guard plate 301 and the sheath 302 to be pulled out, and because the weight of the whole material blocking device is mainly concentrated on the main guard plate 1, after the guard plate is detached, the weight of the auxiliary guard plate 301 and the sheath 302 is only 1/3 of the weight of the material blocking device, so that the maintenance personnel can be completed only by 2-3 maintenance personnel.

Similarly, when the sheath 302 is installed, after the sheath 302 on the detached auxiliary guard plate 301 is updated, the auxiliary guard plate 301 and the sheath 302 are sent into the belt conveyor from the end head of the belt conveyor, the auxiliary guard plate 301 is inserted into the leakage-proof positioning groove 6 of the main guard plate 11, and after the positioning pins 5 fall into the positioning holes 4, the main and auxiliary guard plates 301 connecting bolts 7 are fixed. Only 2-3 maintenance personnel are needed for installing the sheath 302, and the operation time is reduced from the original 4 hours to 1 hour.
