[0002] The 800 belt conveyor is a type of belt conveyor. The 800 belt conveyor hanging device currently used underground has a very high damage rate due to its unreasonable design and cannot meet the requirements of safety standards. It has the following problems:
[0003] 1. The hook adopts a semi-ring structure. The hook does not form a closed loop. Although it can suppress the wire inlet, when the 800 belt conveyor stops suddenly, the wire will often fall off the semi-ring.
[0004] 2. The original old 800 belt conveyor hanging device is mostly fixed on the 800 belt pull strip during installation (the pull strip is made of 2-inch tube). The U-bolt and the pull strip are in line contact, which causes the 800 belt hanging device to often move during use and cannot be effectively fixed neatly.
[0005] 3. The original old 800 belt conveyor hanging device fixed the half ring of the emergency stop wire and the hook angle iron at one point welding, which was not firmly fixed and the half ring of the emergency stop wire often fell off.
[0006] Therefore, 800 belt hooks are proposed. Utility Model Content
[0007] The utility model provides an 800 belt hook, aiming to solve the above problems.

[0009] Preferably, the hook angle iron is made of No. 45 galvanized angle steel, and the cross section of the hook angle iron is a V-shaped structure.
[0010] Preferably, there are two semicircular grooves in total, and the two semicircular grooves are arranged on the outer wall of one side of the hook angle iron at a certain interval, and the inner wall of the semicircular groove matches and fits with the outer wall of the semicircular ring.
[0011] Preferably, the extended arc rod 1 and the extended arc rod 2 are combined with the semicircular ring to form a spiral shape, and the extended arc rod 1 and the extended arc rod 2 are staggered by 40%.
[0012] Preferably, the U-shaped rod, screw rod and nut are made of M12 round steel, and the inner side wall of the U-shaped rod is in a flat state.
[0013] Preferably, there are two positioning holes and two screw rods, and the two positioning holes and the two screw rods are respectively arranged on one side outer wall of the hook angle iron and at both ends of the U-shaped rod.
[0014] Preferably, the pressed groove passes through the hook angle iron.
[0015] Preferably, the screw passes through the positioning hole.
[0016] Compared with the prior art, the embodiments of the present application have the following beneficial effects:
[0017] By spirally arranging the extended arc rod 1 and the extended arc rod 2 at both ends of the semicircular ring, the length of the semicircular ring can be increased so that the staggering of the hanging line can reach 40%, which has a certain closing effect and prevents the pull line from falling out during emergency stop. By squeezing out a pressing groove on the outer wall of the hook angle iron, the hook angle iron is in contact with the belt pull surface, which increases the friction during fixation and ensures the firm installation. The flattened U-shaped rod is further used to achieve the contact between the U-shaped rod and the belt pull surface, avoiding the movement of the belt hanging device during use and ensuring that the fixed hanging device is neat. The line contact welding between the semicircular groove and the semicircular ring can ensure the firm strength of the welding and prevent the semicircular ring of the emergency stop pull line from falling off.

[0024] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0025] The utility model embodiment provides 800 belt hooks, such as Figure 1-4 As shown, it includes a hook angle iron 1, which is made of 45# galvanized angle steel. The steel thickness of 45# galvanized angle steel reaches 6mm, which can ensure that the hook angle iron 1 does not deform when tightened and can meet the use requirements. The corrosion resistance of 45# galvanized angle steel is increased by galvanizing. The 45# galvanized angle steel after galvanizing forms a neat slope with the belt, which is beautiful and generous. The cross section of the hook angle iron 1 is a V-shaped structure, and a semicircular groove 2 is provided on the outer wall of one side of the hook angle iron 1. A semicircular ring 3 is welded on the inner wall of the semicircular groove 2. There are two semicircular grooves 2 in total, and the two semicircular grooves 2 are arranged on the outer wall of one side of the hook angle iron 1 at a certain distance. The inner wall of the semicircular groove 2 matches the outer wall of the semicircular ring 3, and the semicircular groove 2 and the semicircular ring 3 are fixed by wire welding. One end of the semicircular ring 3 is integrally formed with an extended arc rod 4, and the semicircular ring 3 The other end is integrally formed with an extended arc rod 2 5, and a pressing groove 6 is provided on the outer wall of one side of the hook angle iron 1 adjacent to the semicircular groove 2, and the pressing groove 6 passes through the hook angle iron 1, and a positioning hole 7 is provided on the outer wall of one side of the hook angle iron 1 near the pressing groove 6. A U-shaped rod 8 is provided at one side of the hook angle iron 1, and a screw 9 is integrally formed at one end of the U-shaped rod 8. The U-shaped rod 8, screw 9 and nut 10 are made of M12 round steel. The U-shaped rod 8, screw 9 and nut 10 made of M12 round steel can ensure its structural strength and avoid damage caused by disengagement when tightened. There are two positioning holes 7 and two screws 9, and the two positioning holes 7 and the two screws 9 are respectively arranged on the outer wall of one side of the hook angle iron 1 and at both ends of the U-shaped rod 8. The outer side wall of the screw 9 is connected with a nut 10 by threaded engagement, and the screw 9 passes through the positioning hole 7.
[0026] It should be noted that due to the unreasonable design of the existing 800 belt conveyor hanging device, the damage rate is extremely high and it cannot meet the requirements of safety standardization. In this embodiment, the extended arc rod 1 4 and the extended arc rod 2 5 are spirally arranged at both ends of the semicircular ring 3, which can increase the length of the semicircular ring 3 so that the hanging line is staggered to 40%, and has a certain closing effect, which can prevent the pull line from falling out during emergency stop. By squeezing out a pressing groove 6 on the outer wall of the hook angle iron 1, the hook angle iron 1 is in contact with the belt pull surface, which increases the friction during fixation and ensures the firmness of the installation. The flattened U-shaped rod 8 is further used to achieve the U-shaped rod 8 belt pull surface contact, which avoids the movement of the belt hanging device during use and ensures that the fixed hanging device is neat. The line contact welding between the semicircular groove 2 and the semicircular ring 3 can ensure the firm strength of the welding and avoid the semicircular ring 3 of the emergency stop pull line from falling.
[0027] Specifically, in this embodiment, this scheme mainly includes a hook angle iron 1, a semicircular ring 3 and a U-shaped rod 8. When in use, the semicircular ring 3 is welded to the inner wall of the semicircular groove 2, and the welding point is linearly welded. The pressing groove 6 on the hook angle iron 1 is fitted with the pull rod on the 800 belt conveyor. At this time, the screw 9 on the U-shaped rod 8 is passed through the positioning hole 7, and the U-shaped rod 8 is sleeved on the outside of the pull rod. The nut 10 is threaded on the screw 9. As the nut 10 is gradually tightened, the U-shaped rod 8 gradually squeezes the pull rod, and finally the flattened part of the U-shaped rod 8 is tightly attached to the outside of the pull rod. The fastening force is used to realize the installation and fixation of the belt hook, and the pull wire is passed through the semicircular ring 3. The extended arc rod 1 4 and the extended arc rod 2 5 limit the up and down fluctuating pull wire to prevent the pull wire from falling out of the semicircular ring 3.
[0028] In a further preferred embodiment of the present invention, Figure 1 and Figure 4 As shown, the extended arc rod 1 4 and the extended arc rod 2 5 are combined with the semicircular ring 3 to form a spiral shape, and the extended arc rod 1 4 and the extended arc rod 2 5 are staggered by 40%.
[0029] In this embodiment, the length of the semicircular ring 3 can be increased by extending the spiral arc rod 1 4 and the extended arc rod 2 5 so that the hanging wire is staggered by 40%, which has a certain closing effect and prevents the wire from falling out during emergency stop.
[0030] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the inner side wall of the U-shaped rod 8 is in a flat state.
[0031] In this embodiment, the flattened U-shaped rod 8 further enables the U-shaped rod 8 to contact the belt pull surface, thereby avoiding the movement of the belt hanging device during use and ensuring that the fixed hanging device is neat.
