Description

Technical Field

[0001] This utility model relates to the field of chain conveyor technology, and in particular to an anti-deviation guide wheel for chain conveyors. Background Technology

[0002] Chain conveyors, as core continuous conveying equipment in industries such as metallurgy, mining, and building materials, play a crucial role in material transfer in industrial production processes. For ultra-heavy materials such as scrapped automobiles, large metal components, and large blocks of ore, subsequent recycling through smelting or crushing is necessary for resource recovery. Under certain specific operating conditions, the transfer of these materials places stringent requirements on chain conveyors for continuous operation and long-distance transport. To ensure stable transport under such high-load conditions and prevent downtime or malfunctions caused by chain misalignment, dedicated anti-misalignment devices are required for chain conveyors.

[0003] Currently, the inner and outer sleeve anti-deviation device commonly used in chain conveyors works by using the cooperation of the inner and outer sleeves to correct deviation. The inner sleeve is usually fixed to the conveyor frame as a fixed reference; the outer sleeve is connected to the guide structure on the side of the chain plate. When the chain plate deviates, the outer sleeve will move in the direction of the chain plate's deviation. Through the limiting or guiding effect between the sleeves, a corrective force is applied in the opposite direction to pull the chain plate back to the normal conveying track.

[0004] Under actual stress conditions, due to the lack of multi-point force self-balancing capability, local stress will continuously exceed the reasonable range. Long-term accumulated stress will force internal and external components to form abnormal conical contact, disrupting operational stability and causing operational imbalance. This leads to a sharp increase in unilateral stress on the chain, significantly reducing its safety factor. If extreme situations such as excessive material impact occur at this time, the risk of chain breakage will directly increase. Chain breakage not only causes equipment downtime but may also trigger safety accidents, posing a serious threat to the long-term stable operation of the equipment. Summary of the Invention

[0005] The purpose of this utility model is to provide an anti-deviation guide wheel for a chain conveyor, which can actively adjust and balance the lateral force when the roller body and the T-shaped chain plate rotate and come into contact. This avoids wear caused by rigid connection and prevents imbalance caused by large force, which would lead to failure of the anti-deviation effect. This provides a reliable guarantee for the stable operation of the device when conveying materials, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-deviation guide wheel for a chain conveyor, comprising a conveyor frame body, wherein an mounting shell is fixedly installed at the axial end of the conveyor frame body, and an anti-deviation mechanism is provided inside the mounting shell;

[0007] The anti-deviation mechanism includes a roller body that extends into the interior of the mounting housing, and a roller shaft that extends out from the interior of the roller body. A self-aligning roller bearing is fixedly installed between the roller shaft and the roller body, and sealing oil seals are fixedly installed at both ends of the self-aligning roller bearing. End caps are fixedly installed at the top and bottom ends of the roller body.

[0008] Preferably, a shaft end fixing cover is fixedly installed on the top of the mounting shell, and a fixing bolt protrudes from the inside of the shaft end fixing cover.

[0013] Preferably, a retaining wheel seat is fixedly installed at the bottom of the mounting shell, a frame longitudinal beam is fixedly installed on one side of the axial retaining wheel seat of the conveyor frame body, and a frame crossbeam is fixedly installed on one side of the frame longitudinal beam below the T-shaped chain plate inside the conveyor frame body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the cooperation of the roller body, roller shaft, roller bearing, sealing oil seal, end cover and shaft end fixing cover, can actively adjust and balance the lateral force when the roller body rotates and contacts the T-shaped chain plate. This avoids wear caused by rigid connection and prevents imbalance due to large force, which would lead to failure of the anti-deviation effect, thus providing a reliable guarantee for the stable operation of the device when conveying materials.

[0016] 2. This utility model, through the cooperation of overflow skirt, material baffle, guide wheel seat, frame longitudinal beam and frame transverse beam, can effectively limit the conveyed material, significantly reducing the risk of material overflow or deviating from the conveying path; at the same time, the installation position of the anti-deviation mechanism can be flexibly set according to the actual operating requirements of the conveyor.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 5An anti-deviation guide wheel for a chain conveyor includes a conveyor frame body 1, an mounting shell 2 is fixedly installed at the axial end of the conveyor frame body 1, and an anti-deviation mechanism 3 is provided inside the mounting shell 2.

[0028] The anti-deviation mechanism 3 includes a roller body 301, which extends into the interior of the mounting housing 2. A roller shaft 302 extends out from the interior of the roller body 301. A roller bearing 303 is fixedly installed between the roller shaft 302 and the roller body 301. Sealing oil seals 304 are fixedly installed at both ends of the roller bearing 303. End caps 305 are fixedly installed at both the top and bottom ends of the roller body 301. A shaft end fixing cap 306 is fixedly installed at the top of the mounting housing 2. A fixing bolt 307 protrudes from the inside of the fixing cover 306. Maintenance walkways 4 are fixedly installed on both sides of the outer wall of the conveyor frame body 1. A protective frame 5 is fixedly installed on the side of the maintenance walkway 4 away from the conveyor frame body 1. A guide trough 6 is opened at the top of the conveyor frame body 1. A T-shaped chain plate 7 is rotatably connected inside the guide trough 6. Roller wheel bodies 301 are located on both sides of the T-shaped chain plate 7. The roller wheel bodies 301 are evenly distributed at equal intervals with respect to the outer wall surface of the conveyor frame body 1.

[0029] By adopting the above technical solution, under the support of the mounting shell 2, the roller body 301 rotates and abuts against both sides of the T-shaped chain plate 7. According to the equidistant distribution of the T-shaped chain plate 7, a long-distance anti-deviation effect is achieved. The roller body 301 contacts the T-shaped chain plate 7 through the roller shaft 302 and the roller bearing 303, which balances the lateral force generated when the track deviates in real time, avoids the chain plate from deviating, and thus automatically balances the lateral multi-point force. It allows the wheel body to make fine adjustments to the angle when the force is uneven, avoids excessive wear and breakage in some areas, maintains the overall stability, and improves the service life of the entire device. It should be noted that the roller body 301 is rotated rather than fitted. The sealing oil seals 304 and end caps 305 at both ends of the roller body 301 play a role in sealing, dust prevention, and protection. The maintenance walkway 4 and the protective frame 5 reserve space for workers to carry out maintenance.

[0030] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a guide component 8 is provided on one side of the protective frame 5. The guide component 8 includes an overflow skirt 801, which is fixedly installed on the top of the protective frame 5. A material baffle 802 is fixedly installed on one end of the overflow skirt 801. A wheel stop seat 9 is fixedly installed on the bottom of the mounting shell 2. A frame longitudinal beam 10 is fixedly installed on one side of the wheel stop seat 9 along the axis of the conveyor frame body 1. A frame cross beam 11 is fixedly installed on one side of the frame longitudinal beam 10 below the T-shaped chain plate 7 inside the conveyor frame body 1.

[0031] By adopting the above technical solution, the cooperation of the overflow skirt 801 and the material baffle 802 can prevent the material from overflowing when it is conveyed inside the guide chute 6, and it is conveyed above the T-shaped chain plate 7. In conjunction with the cooperation of the frame longitudinal beam 10 and the frame cross beam 11, anti-deviation mechanisms 3 are installed in different areas. The upper anti-deviation mechanism 3 is equipped with a wheel stop seat 9 for fixing and contacting the T-shaped chain plate 7. The lower anti-deviation mechanism 3, with the cooperation of the mounting shell 2, directly fits with the return roller and other components of the conveyor, further improving the anti-deviation effect. At the same time, the position of the mounting shell 2 is not fixed and needs to be adjusted according to the position of the conveyor frame body 1 to meet the rotational resistance of the roller body 301, thereby achieving the anti-deviation effect.

[0032] Working principle: The conveyor consists of a main frame 1, T-shaped chain plates 7, frame longitudinal beams 10, frame transverse beams 11, chains, guide rails, return rollers, tensioning system, drive system, and control system. This is conventional technology and will not be elaborated further. The roller shaft 302, supported by the mounting shell 2, engages with the roller body 301 via roller bearings 303, automatically balancing pressure. Simultaneously, the sealing oil seal 304 and end cap 305 provide a dustproof seal, and the shaft end fixing cap 306 is secured to the mounting shell with fixing bolts 307. To further improve stability, the main body of the conveyor frame 1 is equipped with a maintenance walkway 4 for workers to walk and inspect the device. It also works with the protective frame 5 to reinforce and protect the equipment. During material conveying, the overflow skirts 801 and material baffles 802 on both sides of the guide chute 6 prevent detachment. The anti-deviation mechanism 3 is set in two sets, upper and lower. The upper anti-deviation mechanism 3 is fixed by the wheel stop seat 9, which facilitates alignment and prevents deviation. The lower mechanism directly acts on the return support roller of the main body of the conveyor frame 1 to further improve the anti-deviation effect.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
