Description

Technical Field

[0001] This invention relates to the field of open-pit mining and long-distance conveying equipment technology, specifically an energy-saving end-side steep-angle conveyor. Background Technology

[0002] Commonly used steep-angle belt conveyors include patterned belt conveyors, corrugated sidewall belt conveyors, and partition belt conveyors. These belt conveyors require special belts, which have high manufacturing and maintenance costs, short service life, are prone to material spillage, and are difficult to clean. In recent years, pressed belt conveyors have emerged for conveying bulk materials at steep angles. Compared with other types of steep-angle belt conveyors, pressed belt conveyors have advantages such as low cost, easy cleaning and repair, and no spillage or dust generation during transportation. Patent CN116280890A discloses a pressure roller assembly for a pressing device in a pressed belt conveyor. Its key technical feature is that it includes a caster frame and several casters connected to the caster frame. The casters are pressed against the surface of the cover belt of the pressed belt conveyor by pressure obtained from the pressing device frame hinged to the caster frame. The pressure roller assembly for the belt pressing device of the belt pressing conveyor includes a caster frame and several casters connected to the caster frame. The casters replace the pressure rollers of the existing belt pressing device to provide pressure to the cover belt. The swing of the casters minimizes the friction restriction of the belt pressing device on the lateral movement of the conveyor belt, reduces the resistance to the lateral movement of the cover belt, makes the lateral movement of the cover belt more free, and improves the smoothness of the cover belt movement.

[0003] Currently, the following problems still exist with inclined conveyors in open-pit mining:

[0004] 1. When using special tapes, the price is high, the lifespan is short, the carrying capacity is limited, it is not easy to clean, and the filling rate is less than 50%.

[0005] 2. When using a belt press conveyor, the pressure of the belt press cannot be well controlled. If the pressure is too low, it will not be able to stop material leakage, while if the pressure is too high, it will increase the belt indentation resistance and increase operating costs. At the same time, when the material passes over the idler rollers, it is easy to get stuck, which can easily scratch the belt and affect its service life.

[0006] 3. Currently, steep-angle belt conveyors cannot travel along the side slope of open-pit mines and cannot adapt to slope undulations.

[0007] In conclusion, how to effectively solve the above problems is a problem that needs to be addressed by those skilled in the art. Summary of the Invention

[0008] The purpose of this invention is to provide an energy-saving end-side large-angle conveyor to solve the problems mentioned in the background art.

[0014] The belt roller steering devices at both ends are connected to form a closed loop by belt roller tracks. The belt roller assemblies are connected in series by flexible transmission components to form a closed loop and travel within the closed loop formed by the belt roller steering devices and belt roller tracks.

[0015] The bearing wheel steering devices at both ends are connected by bearing wheel tracks to form another closed loop, and the bearing wheel assemblies are connected by flexible transmission components to form a closed loop that travels within the closed loop formed by the bearing wheel steering devices and the bearing wheel tracks.

[0016] The tape and the material inside are sandwiched between the pressure roller assembly and the support roller assembly and move synchronously. The pressure roller assembly and the support roller assembly press the tape into an "S" shape.

[0017] As a preferred embodiment of the present invention, the adjustable tail receiving section consists of a tail frame, a buffer bed, a hopper, a tail reversing roller, a roller, a belt alignment cylinder, a connecting seat, and an adjusting cylinder.

[0018] The tail-end redirecting roller is installed at the tail of the tail frame and is used for belt redirection. Its angle can be adjusted by the belt deviation adjustment cylinder to realize the belt deviation adjustment function.

[0019] The buffer bed, hopper, and idler rollers are installed above the tail frame to receive material from the transfer belt conveyor.

[0020] The adjustable tail receiving section is mounted on the first traveling track chassis via a connecting seat;

[0021] The tail frame is connected to the connecting seat via a pin and an adjusting cylinder, and the connecting seat is mounted on the first tracked chassis.

[0022] The adjustable tail section for receiving materials is angled by adjusting the hydraulic cylinder to achieve optimal material receiving.

[0023] As a preferred embodiment of the present invention, the tail transition section is arranged on the first tracked chassis.

[0024] As a preferred embodiment of the present invention, the tape includes an upper pressing tape and a lower supporting tape.

[0025] The pressure roller assembly includes two pressure brackets arranged vertically opposite to each other on both sides. Two pressure rollers are arranged vertically between the two pressure brackets on both sides. A first roller shaft is fixedly inserted at the central axis of each pressure roller. The two ends of the first roller shaft are respectively movably connected to the pressure bracket through bearings.

[0026] The middle part of the opposite side of the pressure belt brackets on both sides is fixedly connected to the first rail block of the corresponding sliding pressure belt wheel track;

[0027] The upper pressure tape forms a closed loop through the pressure roller assembly, and the upper pressure tape passes between the two pressure rollers.

[0028] As a preferred embodiment of the present invention, the bearing wheel assembly includes bearing brackets arranged laterally on both sides opposite each other, and two bearing rollers distributed on the left and right are arranged between the bearing brackets on both sides. A second roller shaft is fixedly inserted at the central axis of each bearing roller, and the two ends of the second roller shaft are respectively movably connected to the bearing brackets through bearings.

[0030] The lower support belt forms a closed loop through the support wheel assembly, and the lower support belt is attached to the two support rollers;

[0031] The center of the bearing roller is recessed.

[0032] As a preferred technical solution of the present invention, the roller unit bodies of the steep incline belt conveyor are connected by unit body attitude adjustment cylinders to form a body assembly. The unit body attitude adjustment cylinders are used to adjust the attitude of the body assembly to realize that the steep incline belt conveyor changes with the slope.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] (1) An energy-saving end-side large-angle conveyor with an innovative structural design that eliminates bending resistance and indentation resistance of the belt, reducing running resistance by 40% and operating power by 30%. The roller unit body of the large-angle belt conveyor makes the belt run more smoothly through the coordinated work of the pressure roller assembly and the bearing roller assembly, reducing energy loss and lowering long-term operating costs.

[0035] (2) An energy-saving end-side steep-angle conveyor, wherein the pressure roller assembly and the load-bearing roller assembly on the upper and lower parts of the roller unit of the steep-angle belt conveyor operate synchronously, and part of the force is borne by the flexible transmission component connecting the pressure roller assembly and the load-bearing roller assembly, which reduces the belt strength by 30%. While ensuring conveying performance, a lower-cost belt can be selected, while reducing the risk of belt damage due to excessive force and extending the belt's service life.

[0036] (3) An energy-saving end-side large-angle conveyor breaks the traditional conveyor sag limitation, realizes the "S" shaped arrangement of the belt, and can use ordinary belts for large-angle conveying. This changes the previous situation where large-angle conveying relied on special belts, reduces the belt procurement and maintenance costs, and broadens the application range of the conveyor.

[0037] (4) An energy-saving end-side steep-angle conveyor can realize the steep-angle belt conveyor to change with the slope, with strong environmental adaptability. Through the unit body posture adjustment cylinder, the body posture can be adjusted in real time according to the undulation of the open-pit mine end-side slope, ensuring the stable operation of the conveyor, reducing the conveying problems caused by terrain changes, and improving the reliability of the equipment.

[0038] (5) An energy-saving end-side large-angle conveyor, wherein the belt pressing wheel assembly and the bearing wheel assembly press the belt into an "S" shape. When the belt is lifted at a large angle, the friction between the material and the belt when the material slides down is converted into the positive pressure of the material on the belt. The sliding resistance is significantly increased, which effectively improves the material sliding situation, ensures the stable conveying of the material when the belt is conveyed at a large angle, reduces material spillage, and improves the conveying efficiency.

[0039] (6) An energy-saving end-side large-angle conveyor adopts a roller unit body of 12 meters per section for large-angle belt conveyors. The bearing wheels on the bearing wheel assembly are changed from a series structure to a parallel structure. The tension of the flexible transmission component on each large-angle belt conveyor roller unit body is reduced, which effectively reduces the risk of breakage of the flexible transmission component and reduces the failure rate. This structural optimization improves the overall reliability of the equipment and reduces downtime and maintenance costs caused by failure.

[0040] (7) An energy-saving end-side large-angle conveyor, wherein the bearing wheel assembly and the pressure wheel assembly on the upper and lower parts of the roller unit of the large-angle belt conveyor operate synchronously through a flexible transmission component. The upper pressure belt and the lower bearing belt start synchronously, which effectively reduces the elastic effect of the belt when it starts, reduces the tension force and tension stroke, reduces the wear of the belt during the start-up process, reduces the requirements for the tensioning device, and further reduces the equipment cost and maintenance difficulty.

[0041] (8) An energy-saving end-side large-angle conveyor, which adopts a roller unit for large-angle belt conveyor. The roller unit for large-angle belt conveyor has a short distance and fast response speed, which can effectively reduce the start-up time of the conveyor, improve the working efficiency of the equipment, reduce the waste of energy in the start-up stage, and enable the conveyor to be put into work more quickly.

[0042] (9) An energy-saving end-side large-angle conveyor that is completely sealed during transportation, realizes environmental protection function, avoids dust and leakage of materials during transportation, reduces pollution to the environment, meets environmental protection requirements, and is especially suitable for workplaces that are sensitive to the environment.

[0043] (10) An energy-saving end-side large-angle conveyor, which can achieve 100% filling rate because the belt, pressure roller assembly and bearing roller assembly operate synchronously, greatly increases the conveyor's transport capacity, improves production efficiency, and meets the needs of large-scale production.

[0044] (11) An energy-saving end-side large-angle conveyor, wherein the roller unit body of the large-angle belt conveyor adopts a 12-meter unit, and the bearing wheel track and the pressure wheel track adopt a whole profile without joints. The bearing wheel assembly and the pressure wheel assembly avoid noise when passing through the joint during operation, and have a noise reduction function, creating a quieter working environment for operators and reducing the impact of noise on the surrounding environment.

[0045] (12) An energy-saving end-side steep-angle conveyor, which adopts a first walking track chassis and a second walking track chassis, can travel along the slope, reduce the time of moving the machine, improve the mobility of the equipment, facilitate operation in different locations in open-pit mines, can quickly adapt to changes in mining areas, and improve work efficiency.

[0046] (13) An energy-saving end-side large-angle conveyor can realize large-angle conveying using ordinary conveyor belts, with an angle range of 0-70 degrees, which enhances the versatility and applicability of the conveyor and can meet the large-angle conveying needs under different working conditions.

[0047] (14) An energy-saving end-side steep-angle conveyor can effectively solve the problem of the intersection of the open-pit mine truck passage and the belt conveyor line. Through the flexible body design and adjustable posture, it avoids the conflict between the transport lines and improves the space utilization and transport safety of the open-pit mine.

[0048] (15) An energy-saving end-side steep-angle conveyor uses a common conveyor belt, which is easy to clean. Compared with the special belt used in traditional steep-angle conveyors, the common conveyor belt is easier to clean, reducing the time and labor costs required for cleaning and improving the convenience of equipment maintenance.

[0049] (16) An energy-saving end-side steep-angle conveyor can realize the overlapping of multiple conveyors along the slope and can be used at any height, which improves the flexibility and expandability of the conveyor system. It can be combined and arranged according to different production needs and site conditions to adapt to complex conveying tasks. Attached Figure Description

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] Example: Please refer to Figures 1-17 An energy-saving end-side steep-angle conveyor includes several steep-angle belt conveyor roller units body 1, tail drive transition section 2 and head drive transition section 3;

[0070] A first tracked chassis 401 is provided between the roller unit body 1 of the large-angle belt conveyor and the tail drive transition section 2, and a second tracked chassis 402 is provided between the roller unit body 1 of the large-angle belt conveyor and the head drive transition section 3.

[0071] Tail drive transition section 2 includes an adjustable tail receiving section 201 and a tail transition section 202;

[0072] Several roller unit bodies 1 of the large-angle belt conveyor are respectively equipped with unit body attitude adjustment cylinders 5;

[0073] The roller unit body 1 for the large-angle belt conveyor consists of a bearing wheel steering device 101, a bearing wheel track 102, a bearing wheel assembly 103, a pressure wheel steering device 104, a pressure wheel track 105, a pressure wheel assembly 106, a truss 107, a body connecting seat 108, and a flexible transmission component.

[0074] The roller unit body 1 for the steep angle belt conveyor can be of any length, but based on a comparison of power and cost, a 12m section is preferred.

[0075] The pressure roller steering devices 104 at both ends are connected to form a closed loop by pressure roller tracks 105. The pressure roller assemblies 106 are connected in series by flexible transmission components to form a closed loop and travel within the closed loop formed by the pressure roller steering devices 104 and pressure roller tracks 105.

[0077] The belt 6 and the material inside it are sandwiched between the pressure roller assembly 106 and the support roller assembly 103 and run synchronously. The pressure roller assembly 106 and the support roller assembly 103 press the belt 6 into an "S" shape. When running at a large angle, the friction between the material and the belt 6 when it slides down is converted into the positive pressure of the material on the belt 6, and the sliding resistance is significantly increased, which effectively improves the sliding of the material.

[0078] The flexible transmission component is preferably a steel wire rope or chain.

[0079] The adjustable tail receiving section 201 consists of a tail frame 203, a buffer bed 204, a hopper 205, a tail reversing roller 206, an idler roller 207, a belt alignment cylinder 208, a connecting seat 209, and an adjusting cylinder 210.

[0080] The tail-end redirecting roller 206 is installed at the tail of the tail frame 203 and is used for belt redirection. The angle can be adjusted by the belt deviation adjustment cylinder 208 to realize the belt deviation adjustment function.

[0081] The buffer bed 204, hopper 205, and idler roller 207 are installed above the tail frame 203 to receive material from the transfer belt conveyor;

[0082] The adjustable tail receiving section 201 is mounted on the first traveling track chassis 401 via a connecting seat 209;

[0083] The tail frame 203 is connected to the connecting seat 209 via a pin and an adjusting cylinder 210. The connecting seat 209 is mounted on the first tracked chassis 401.

[0084] The adjustable tail section 201 is angled by adjusting the hydraulic cylinder 210 to achieve the optimal material receiving state.

[0085] The tail transition section 202 is arranged on the first tracked chassis 401. Its main function is to achieve an effective transition between the adjustable tail receiving section 201 and the roller unit body 1 of the large-angle belt conveyor, so as to avoid material spillage.

[0086] The tape 6 includes an upper pressure tape 601 and a lower support tape 602.

[0087] The pressure roller assembly 106 includes pressure brackets 109 arranged vertically on both sides, and two pressure rollers 110 arranged vertically between the pressure brackets 109 on both sides. A first roller shaft 111 is fixedly inserted at the central axis of each pressure roller 110, and the two ends of the first roller shaft 111 are respectively movably connected to the pressure brackets 109 through bearings.

[0088] The middle part of the opposite side of the pressure belt brackets 109 on both sides is fixedly connected to the first rail block 112 of the corresponding sliding pressure belt wheel rail 105;

[0089] The upper pressure tape 601 forms a closed loop through the pressure roller assembly 106, and the upper pressure tape 601 passes between the two pressure rollers 110.

[0090] The bearing wheel assembly 103 includes bearing brackets 113 arranged laterally on both sides opposite each other. Two bearing rollers 114 are arranged between the bearing brackets 113 on both sides. A second roller shaft 115 is fixedly inserted at the central axis of each bearing roller 114. The two ends of the second roller shaft 115 are respectively movably connected to the bearing brackets 113 through bearings.

[0091] The middle part of the opposite side of the two bearing brackets 113 is respectively fixedly connected to the second rail block 116 of the corresponding sliding bearing wheel rail 102;

[0092] The lower support belt 602 forms a closed loop through the support roller assembly 103, and the lower support belt 602 is attached to the two support rollers 114;

[0093] The middle part of the bearing roller 114 is recessed.

[0094] The roller unit body 1 of the steep incline belt conveyor is connected to form a body group by a unit body attitude adjustment cylinder 5. The unit body attitude adjustment cylinder 5 is used to adjust the attitude of the body group so that the steep incline belt conveyor can change with the slope.

[0095] The number of roller units for the large-angle belt conveyor in the machine body assembly is determined according to the operating conditions.

[0096] The roller unit body 1 for steep-angle belt conveyors can be converted into a conventional conveyor.

[0097] The working principle of this invention is as follows:

[0098] Energy-saving end-side steep-angle conveyors achieve steep-angle material conveying mainly through the cooperation of their various components.

[0099] The adjustable tail section receiving section 201 is responsible for receiving material from the transfer belt conveyor. The tail deflector roller 206 can be angled via the belt alignment cylinder 208 to achieve belt deflection and alignment functions, ensuring that the conveyor belt 6 maintains good operating condition during material receiving. The buffer bed 204, hopper 205, and idler roller 207 are installed above the tail frame 203. The hopper 205 receives the material, the buffer bed 204 reduces the impact of the material on the conveyor belt 6, and the idler roller 207 supports the conveyor belt 6, allowing the material to fall smoothly onto the conveyor belt 6. The tail frame 203 is connected to the connecting seat 209 via a pin and an adjusting cylinder 210. The adjustable tail section receiving section 201 can be angled via the adjusting cylinder 210 to achieve the optimal material receiving condition.

[0100] Multiple roller unit bodies 1 of the inclined belt conveyor are connected by unit body attitude adjustment cylinders 5 to form a body assembly, which can adjust the body attitude according to slope changes. The unit body attitude adjustment cylinders 5 can adjust the attitude of the body assembly in real time according to the undulation of the open-pit mine end slope, enabling the inclined belt conveyor to adapt to slope changes. By extending and retracting the unit body attitude adjustment cylinders 5, the relative angle and position between the roller unit bodies 1 of the various inclined belt conveyors are changed, ensuring that the conveyor can maintain good operating condition in complex slope environments, thus improving the adaptability and reliability of the equipment.

[0101] In each roller unit body 1 of a large-angle belt conveyor, the pressure roller steering device 104 and the carrier roller steering device 101 are connected in a closed loop via the pressure roller track 105 and the carrier roller track 102, respectively. The pressure roller assemblies 106 and the carrier roller assemblies 103 are connected in series with wire ropes or chains to form a closed loop, moving within their respective tracks. The pressure roller assemblies 106 and 103 press the belt 6 into an "S" shape. When the conveyor is lifted at a large angle, the friction between the material and the belt 6 as it slides down is converted into a positive pressure force, significantly increasing the sliding resistance and effectively improving material sliding, thus achieving stable large-angle conveying. The belt 6, material, pressure roller assembly 106, and carrier roller assembly 103 operate synchronously, avoiding material jamming and leakage, and reducing wear and scratches on the belt 6.

[0102] The tail transition section 202 is arranged on the first traveling track chassis 401. Its main function is to realize the effective transition between the adjustable tail receiving section 201 and the roller unit body 1 of the large-angle belt conveyor, prevent the material from spilling during the transition, and ensure the continuity and stability of material transportation.

[0103] The head drive transition section 3 provides power to the entire conveyor. The drive unit of the head drive transition section 3 drives the conveyor belt 6, causing the material to be conveyed on the conveyor belt 6 as it moves. Power is transmitted to various components through the conveyor belt 6, realizing continuous material conveying.

[0104] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
