TECHNICAL FIELD

[0001] The utility model relates to a conveying equipment field, concretely relates to a kind of anti-drop lifting lug for belt conveyor straight roller. BACKGROUND

[0002] In the production process of coal mine, efficient, safe material transportation is the key to ensure production continuity and improve economic efficiency. In the conveying process, the belt conveyor mainly realizes the continuous and uniform conveying of powdery or blocky materials through the belt, the upper connecting roller, the lower straight roller, the front and rear rollers, etc. Because it has the characteristics of strong conveying capacity, long conveying distance, simple structure and easy maintenance, it is favored by the coal mine transportation system. Since the straight roller of the existing belt conveyor is directly inserted into the leg hole of the belt conveyor, once the return belt at the lower part of the belt conveyor encounters uneven stress, deviation or foreign matter entrapment, etc., the straight roller shaft is easy to fall off from the side wall of the belt conveyor, affecting the normal operation of the belt conveyor. SUMMARY

[0003] The utility model provides a kind of anti-drop lifting lug for belt conveyor straight roller, it aims at solving the problem that the straight roller of belt conveyor is directly inserted into the leg hole of belt conveyor, leading to the straight roller shaft is easy to fall off from the leg hole of belt conveyor during transportation, affecting the normal operation of belt conveyor.

[0004] To achieve its purpose, the utility model adopts the following technical solutions:

[0005] A kind of anti-drop lifting lug for belt conveyor straight roller, the anti-drop lifting lug is in the shape of 7, the horizontal part of the anti-drop lifting lug is provided with a connecting hole, the anti-drop lifting lug is connected to the side of the belt conveyor by inserting a bolt into the connecting hole, the outer side of the longitudinal part of the anti-drop lifting lug is provided with a boss, an installation hole is formed through the boss, and the straight roller of the belt conveyor is inserted into the installation hole at both ends.

[0006] Further, the shaft head of the straight roller of the belt conveyor is elongated and processed into an oval shape after being elongated, and a through hole is drilled.

[0007] Further, the installation hole is in the shape of an ellipse, and the size of the installation hole is matched with the shaft head of the end part of the straight roller.

[0008] Further, the protruding end part of the straight roller is locked by a split pin after being inserted into the installation hole at both ends.

[0009] Further, the thickness of the boss is 20-30mm.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The anti-falling lug for the straight supporting roller of the adhesive tape conveyor, adopts the 7-shaped structure, ensures the fixed connection of the anti-falling lug horizontal part and the adhesive tape conveyor side part, and the anti-falling lug longitudinal part can also provide support for the straight supporting roller of the adhesive tape conveyor, solves the falling of the straight supporting roller caused by uneven stress of the adhesive tape, deviation or foreign matter rolling in and the like.

[0012] 2. The anti-falling lug for the straight supporting roller of the adhesive tape conveyor is made of a steel plate, simple to manufacture, low in cost, and convenient to disassemble, repair and maintain. BRIEF DESCRIPTION OF DRAWINGS

[0019] The utility model will be further described in connection with the drawings:

[0020] For example, Figures 1-5 ​As shown, the utility model is a kind of anti-drop lug for straight carrier roller of adhesive tape conveyor, the straight carrier roller 3 both ends shaft head of adhesive tape conveyor 1 are lengthened 20mm after processing into oval, and there is 4mm diameter through-hole at 4mm distance end part.Present anti-drop lug 2 is 7-shaped, and two connecting holes 4 are symmetrically arranged in the horizontal part of anti-drop lug 2, and anti-drop lug 2 is firmly connected to the side of adhesive tape conveyor 1 by bolt inserted into connecting hole 4.A boss 5 with thickness of 20mm is arranged on the outer side below the longitudinal part of anti-drop lug 2, and oval-shaped mounting hole 6 is arranged through boss 5, and the specification of mounting hole 6 is compatible with the structure of straight carrier roller 3 end part shaft head of adhesive tape conveyor 1, and straight carrier roller 3 both ends are inserted into mounting hole 6 for fixation to prevent falling off.Further prevent straight carrier roller 3 from falling off, after straight carrier roller 3 both ends are inserted into mounting hole 6, the end part is locked by inserting through-hole by split pin 7.

[0021] When installing, first, anti-drop lug 2 is fixed to the side of adhesive tape conveyor 1 by bolt inserted into connecting hole 4, then straight carrier roller 3 end part shaft head is inserted into the mounting hole 6 of both sides anti-drop lug 2, since mounting hole 6 is compatible with the structure of straight carrier roller 3 end part shaft head, when straight carrier roller 3 is inserted into mounting hole 6, straight carrier roller 3 end part shaft head will be fully clamped and fixed with the inner wall of mounting hole 6, to avoid falling off of straight carrier roller 3 due to uneven stress of adhesive tape, deviation or foreign matter winding, etc.Moreover, after straight carrier roller 3 both ends are inserted into mounting hole 6, it is locked by split pin 7, to further enhance the anti-drop effect, to ensure the normal operation of adhesive tape conveyor 1.
