Description

Technical Field

[0001] This utility model relates to the field of corrugated sidewall conveying devices, and in particular to a special conveying unit for wheel-rail corrugated sidewall belt conveyors. Background Technology

[0002] Traditional belt conveyors are one of the most important material handling equipment in my country, capable of continuous long-distance material transport. However, due to their structural characteristics, traditional belt conveyors have the following drawbacks:

[0003] (1) Limited Inclination Angle: Due to the constraint of the friction coefficient between the material and the conveyor belt, the maximum inclination angle of conventional flat belt conveyors is usually less than 20°, which requires the equipment to be arranged in a low inclination angle and long distance. This not only occupies a lot of land resources, but also has high infrastructure construction costs.

[0004] (2) High operating resistance and energy consumption: The indentation resistance and rotational resistance generated by the idler rollers during long-distance conveying significantly increase the power consumption. According to industry research, the energy consumption of the idler rollers can account for 25%-50% of the total energy consumption of the machine, which seriously limits the conveying distance of a single machine.

[0005] Therefore, traditional belt conveyors are unable to meet the needs of material conveying over long distances and at large angles. Utility Model Content

[0006] To overcome the problems of limited transport angle and high operating resistance in traditional belt conveyors mentioned above, this utility model provides a special conveying unit for wheel-rail corrugated sidewall belt conveyors. By combining the corrugated sidewall conveyor belt and wheel-rail assembly, it replaces the traditional idler roller group, which has the beneficial effects of compact structure, convenient operation and maintenance, reduced transport resistance, increased transport angle, increased single-machine conveying distance, and improved transport efficiency.

[0007] The technical solution of this utility model is as follows:

[0008] A dedicated conveying unit for a wheel-rail corrugated sidewall belt conveyor includes a corrugated sidewall conveyor belt and a connecting pipe. The connecting pipe passes through both sides of the corrugated sidewall conveyor belt and is fixedly connected to it. The connecting pipe is also connected to a wheel-rail assembly. The movement of the corrugated sidewall conveyor belt drives the wheel-rail assembly to travel on the track.

[0009] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0010] By combining corrugated sidewall conveyor belts with wheel-rail assemblies to replace traditional idler roller conveyors, the rolling friction between the wheel-rail assembly and the track reduces running resistance and extends the conveying distance. Furthermore, using corrugated sidewall conveyor belts increases the overall conveying angle. Therefore, the combination of wheel-rail and corrugated sidewall conveyor belts solves the problems of high resistance and limited angle inclination in long-distance conveying, fully utilizing the advantages of both wheel-rail and corrugated sidewall belt conveyors to achieve low-resistance conveying over long distances and at large angles, while simultaneously saving operating energy consumption.

[0011] Preferably, the connecting pipe vertically penetrates the sidewalls on both sides of the corrugated sidewall conveyor belt and is fixedly connected to the base belt at the bottom of the corrugated sidewall conveyor belt.

[0012] Its beneficial effects are as follows: the vertical penetration of the connecting pipe through the sidewall allows the wheel-rail assembly connected to the connecting pipe to travel normally on the track, and its travel direction is consistent with the transportation direction; the fixed connection between the connecting pipe and the base belt can enhance the connection stability between the connecting pipe and the corrugated sidewall conveyor belt.

[0013] More preferably, the connecting tube is parallel to the baseband and is fixedly connected to it by fasteners. The fasteners pass through the baseband and the connecting tube sequentially from the bottom surface of the baseband upwards, and their bottom surfaces are flush with the bottom surface of the baseband.

[0014] Its beneficial effect is that this setting method achieves smooth contact between the fastener and the redirecting roller or head roller.

[0015] Preferably, the wheel-rail assembly includes a wheel axle and a traveling wheel sleeved on the wheel axle. The traveling wheel can rotate around the wheel axle and is connected to the track, and can roll on the track.

[0016] Its beneficial effects are that the wheels can roll stably on the track, and the wheel-rail assembly can remain stable when it is in motion.

[0017] More preferably, the walking wheels are made of nylon; the connecting pipe is made of square steel; and the track is made of round steel.

[0018] Its beneficial effects are as follows: the nylon wheels have the advantages of shock resistance, wear resistance, low resistance, and self-lubrication, with excellent physical properties. They can replace metal wheels while reducing the weight of the conveyor unit. The connecting pipe is made of square steel, which has a simple structure, and drilling holes in it has little impact on its mechanical properties. It also reduces the requirements for manufacturing square holes in the corrugated sidewall conveyor belt base.

[0019] More preferably, both ends of the connecting pipe are fixedly connected to a set of wheel-rail assemblies, and the two sets of wheel-rail assemblies are respectively arranged on both sides of the corrugated sidewall conveyor belt.

[0020] Its beneficial effects are as follows: the two sets of wheel-rail assemblies are respectively arranged on both sides of the corrugated sidewall conveyor belt, which can maintain the force balance on both sides of the corrugated sidewall conveyor belt and ensure the stability of the transportation process.

[0021] More preferably, the end of the wheel axle near the corrugated sidewall conveyor belt extends inward and into the connecting pipe, and the fastener passes vertically downward through the connection point of the two to fix them together.

[0022] Its advantages are that this connection method can ensure the stability of the connection between the connecting pipe and the wheel axle, and facilitate the loading and unloading of wheel and rail components as well as the quick replacement of worn wheels.

[0023] In a further preferred embodiment, a bearing is provided between the wheel axle and the traveling wheel, the traveling wheel rotates around the bearing, and an oil cup is arranged at the outer axle end of the wheel axle, the oil cup communicating with the oil cavity inside the wheel axle.

[0024] Its beneficial effect is that lubricating oil is injected from the oil cup into the oil chamber inside the wheel axle and reaches the bearing position to lubricate the bearing.

[0025] More preferably, the bearing is provided in two sets, and a spacer ring sleeved on the wheel axle is connected between the two sets of bearings. The spacer ring is provided with a ring cavity, and the oil cavity in the wheel axle is in communication with the ring cavity.

[0026] Its beneficial effects are as follows: the spacer ring enables the bearings on both sides to be properly preloaded and axially positioned, and its internal ring cavity provides a connection channel that communicates with the bearing position. The lubricating oil can reach the bearing directly through the spacer ring, thereby lubricating the bearing in a convenient and quick manner.

[0027] More preferably, each end face of the traveling wheel is provided with a through cover that is sleeved on the wheel axle, and the through cover and the end face of the traveling wheel are fitted together to form a labyrinth seal; the outer axle end of the wheel axle is also circumferentially connected with a fastener, and a stop washer is provided between the fastener and the through cover.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] Example 1: This example provides the following... Figures 1 to 3 The diagram shows a special conveying unit for a wheel-rail corrugated sidewall belt conveyor, including a corrugated sidewall conveyor belt 1. The corrugated sidewall conveyor belt 1 (also called a sidewall conveyor belt or a large-angle sidewall belt) is a continuous conveyor belt for corrugated sidewall belt conveyors in the field of transportation machinery. Its core feature is that the base belt 12 at the bottom has continuous corrugated vertical sidewalls 11 on both sides. The sidewalls 11 are vertically connected to the base belt 12 and can be used with transverse partitions to achieve high-angle (even vertical) and high-efficiency conveying of bulk materials.

[0036] It also includes connecting pipes 2, which horizontally penetrate and are fixedly connected to the sidewalls 11 on both sides of the corrugated sidewall conveyor belt 1. Several connecting pipes 2 are provided and evenly arranged along the transport direction of the corrugated sidewall belt conveyor. The connecting pipes 2 are also connected to wheel-rail assemblies 3. Specifically, both ends of the connecting pipes 2 extend outward beyond the sidewalls 11 and are fixedly connected to a set of wheel-rail assemblies 3 at each end. Thus, two sets of wheel-rail assemblies 3 are respectively arranged on both sides of the corrugated sidewall conveyor belt 1. This arrangement maintains the force balance on both sides of the corrugated sidewall conveyor belt 1, ensuring the stability of the transport process. The movement of the corrugated sidewall conveyor belt 1 drives the wheel-rail assemblies 3 to travel on corresponding tracks 4. Two tracks 4 are provided and respectively arranged on both sides of the corrugated sidewall conveyor belt 1, parallel to the transport direction, achieving the same running direction as the transport direction. When transporting materials, the head roller drives and moves the corrugated sidewall conveyor belt 1. The corrugated sidewall conveyor belt 1 then travels on the track 4 via the connecting pipe 2, and the wheel rail assembly 3 on both sides provides dynamic support for the corrugated sidewall conveyor belt 1.

[0037] Therefore, the dedicated conveying unit provided in this embodiment, using a combination of a corrugated sidewall conveyor belt 1 and a wheel-rail assembly 3, replaces the traditional idler roller group for support and transport. The rolling friction between the wheel-rail assembly 3 and the track 4 reduces running resistance and extends the conveying distance. Furthermore, using the corrugated sidewall conveyor belt 1 increases the overall conveying angle. Thus, the combination of wheel-rail and corrugated sidewall conveyor belt 1 solves the problems of high resistance and limited angle inclination during long-distance conveying. It fully utilizes the advantages of both wheel-rail and corrugated sidewall belt conveyors, achieving low-resistance conveying over long distances and at large angles, while simultaneously saving operating energy consumption.

[0038] Example 2: Based on Example 1, the connection method between the connecting pipe 2 and the lower corrugated sidewall conveyor belt 1 is optimized. The connecting pipe 2 passes through the sidewalls 11 on both sides of the corrugated sidewall conveyor belt 1 and is perpendicularly connected to the sidewalls 11. This arrangement allows the wheel-rail assembly 3 connected to the connecting pipe 2 to travel normally on the track 4, and its travel direction is consistent with the transportation direction.

[0039] The connecting pipe 2 is located at the lower part of the sidewall 11, and its bottom surface is connected to and fixedly connected to the base belt 12 at the bottom of the corrugated sidewall conveyor belt 1. This connection method can enhance the connection stability between the connecting pipe 2 and the corrugated sidewall conveyor belt 1. The connecting pipe 2 is connected to the base belt 12 in parallel and is fixedly connected to it by fasteners. The fasteners pass through the base belt 12 and the connecting pipe 2 sequentially from the bottom surface of the base belt 12 upwards, and their bottom surfaces are flush with the bottom surface of the base belt 12. The fasteners can be belt-specific screws 21 of standard model DIN15237. These belt-specific screws 21 are wear-resistant, corrosion-resistant, shock-resistant, and impact-resistant, with excellent physical properties. Tighten the belt-specific screw 21. The belt-specific screw 21 passes upward through the bottom surface of the base belt 12 and is fixed by the nut that mates with it above the connecting pipe 2. During the tightening process of the belt-specific screw 21, its head surface is directly pressed into the base belt 12 without using a countersunk hole structure. This setting can reduce damage to the base belt 12, reduce the impact on its mechanical properties, and improve the service life of the base belt 12. It can also achieve smooth contact between the fastener and the redirecting roller or head roller.

[0040] Example 3: Based on Example 1, the wheel-rail assembly 3 is optimized. The wheel-rail assembly 3 includes a wheel axle 32 and a traveling wheel 33 sleeved on the wheel axle 32. The traveling wheel 33 can rotate around the wheel axle 32. The traveling wheel 33 is provided with an annular groove 331 around its circumference. The annular groove 331 is connected to the track 4. The track 4 is made of round steel. The track 4 is inserted into the annular groove 331, which can provide geometric constraints on the traveling wheel 33. The traveling wheels 33 on both sides of the corrugated sidewall conveyor belt 1 are respectively engaged on the two tracks 4. The traveling wheels 33 can roll stably on the tracks 4. The wheel-rail assembly 3 can remain stable when it is running.

[0041] Preferably, the traveling wheels 33 are made of nylon, specifically nylon 1010. These nylon wheels 33 offer advantages such as shock resistance, wear resistance, low resistance, and self-lubrication, exhibiting excellent physical properties. They can replace metal wheels while reducing the weight of the conveyor unit. The connecting pipe 2 is made of square steel. Square steel has a simple structure, and drilling holes in it minimizes the weakening of its mechanical properties. It also reduces the requirements for manufacturing the square holes in the base belt 12 of the corrugated sidewall conveyor belt 1.

[0042] Example 4: Based on Example 3, the connection method between the wheel-rail assembly 3 and the connecting pipe 2 is optimized. The wheel axle 32 of each wheel-rail assembly 3 is fixedly connected to the end of the connecting pipe 2. The end of the wheel axle 32 near the corrugated sidewall conveyor belt 1 extends inward and into the connecting pipe 2. The fastener passes vertically downward through the connection between the two to fix them together. The fastener can be a long bolt 22. The long bolt 22 passes through the connecting pipe 2 and the wheel axle 32. Its upper and lower ends are fixed by matching nuts. This connection method can not only ensure the connection stability between the connecting pipe 2 and the wheel axle 32, but also facilitate the loading and unloading of the wheel-rail assembly 3 and the quick replacement of the worn running wheel 33.

[0043] Example 5: Based on Example 1, the wheel axle 32 and the traveling wheel 33 are optimized, such as... Figure 3 As shown, a bearing 34 is sleeved on the wheel axle 32 and the traveling wheel 33. The bearing 34 is a deep groove ball bearing. The traveling wheel 33 rotates around the bearing 34. An oil cup 35 is also fixed to the end face of the outer axle end of the wheel axle 32. The oil cup 35 communicates with the oil cavity 321 in the wheel axle 32 and adopts a one-way oil injection valve structure. It can be pressurized by a grease gun. The lubricating oil is injected from the oil cup 35 into the oil cavity 321 in the wheel axle 32 and reaches the bearing 34 to lubricate the bearing 34.

[0044] Preferably, two sets of bearings 34 are provided, and a spacer ring 36 sleeved on the wheel axle 32 connects the two sets of bearings 34. The spacer ring 36 is a metal ring structure with an internal cavity 361. Its two end faces are respectively connected to the bearings 34 on both sides, and together with the inner ring surface of the traveling wheel 33 and the bearings 34 on both sides, it forms a cavity 37. This cavity 37 communicates with the cavity 361. The oil cavity 321 in the wheel axle 32 also communicates with the cavity 361. Lubricating oil injected from the oil cup 35 reaches the position of the cavity 361 from the oil cavity 321 in the wheel axle 32, and flows into the cavity 37 from the cavity 361 to lubricate and maintain the bearings 34. The spacer ring 36 enables correct pre-tightening and axial positioning of the bearings 34 on both sides, and its internal cavity 361 provides a connection channel communicating with the bearings 34. Lubricating oil directly reaches the bearings 34 through the spacer ring 36, thereby lubricating the bearings 34 conveniently and quickly.

[0045] In a further preferred embodiment, each end face of the traveling wheel 33 is provided with a through cover 38 that is sleeved on the wheel axle 32. The through cover 38 is embedded in the end face of the traveling wheel 33. The inner side of the through cover 38 is provided with an annular groove and a flange, which are clearance-fitted with the end face of the traveling wheel 33 to form a labyrinth seal, realizing a non-contact physical barrier. This not only does not affect the normal rotation of the traveling wheel 33, but also prevents lubricating oil leakage and blocks external contamination, protecting the internal bearing 34 and oil seal system. The through cover 38 is also connected to the bearing 34, ensuring the connection stability of the bearing 34.

[0046] The outer axle end of the wheel axle 32 is also connected to a fastener in the circumferential direction. The fastener is a round nut 30 and is located on the outside of the cover 38. A locking washer 31 for the round nut 30 is provided between the fastener and the cover 38. The locking washer 31 can prevent the fastener from loosening. The fastener, locking washer 31 and cover 38 work together to fix the axle end of the wheel axle 32.

[0047] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
