Description

Technical Field

[0001] The present invention relates to the technical field of open-pit mining and long-distance conveying equipment, and specifically to an energy-saving large-inclination conveyor for the end slope. Background Art

[0002] The commonly used large-inclination belt conveyors mainly include corrugated belt conveyors, corrugated sidewall belt conveyors, partition belt conveyors, etc. These belt conveyors require special belts, which have high manufacturing and maintenance costs, short service life, easy material spillage, and are not easy to clean. In recent years, a pressure belt conveyor has emerged for large-inclination conveying of bulk materials. Compared with some other forms of large-inclination belt conveyors, the pressure belt conveyor has the advantages of low cost, easy cleaning and repair, no material spillage and no dust generation during transportation. The patent with the publication number CN116280890A discloses a pressure wheel group for a pressure belt device of a pressure belt conveyor. The technical key points are that it includes a universal wheel frame and several universal wheels connected to the universal wheel frame. The universal wheels are pressed against the surface of the covering belt of the pressure belt conveyor by the pressure obtained from the pressure belt device frame hinged to the universal wheel frame. This pressure wheel group for the pressure belt device of the pressure belt conveyor includes a universal wheel frame and several universal wheels connected to the universal wheel frame. It uses several universal wheels to replace the pressure rollers of the existing pressure belt device to provide pressure to the covering belt, and uses the swing of the universal wheels to minimize the frictional limitation of the pressure belt device on the lateral movement of the conveyor belt, reduce the resistance of the covering belt to lateral movement, make the lateral movement of the covering belt more flexible, and improve the smoothness of the movement of the covering belt.

[0003] Currently, the large-inclination conveyor for open-pit mining still has the following problems: 1. When using a special belt, the price is high, the service life is short, the transportation volume is limited, it is not easy to clean, and the filling rate is less than 50%; 2. When using a pressure belt conveyor, the pressure of the pressure belt cannot be well controlled. If the pressure is small, it cannot hold back the leakage of materials. If the pressure is large, it will increase the depression resistance of the belt and increase the operating cost. At the same time, it is easy to get stuck when the material passes over the idler, which is easy to scratch the belt and affect the service life; 3. Currently, the large-inclination belt conveyor cannot walk along the end slope of the open-pit mine and cannot adapt to the undulation of the slope.

[0012] As a preferred technical solution of the present invention, the roller units of the steep-angle belt conveyor are connected by unit body attitude adjustment cylinders to form a body group, and the unit body attitude adjustment cylinders are used to adjust the attitude of the body group to realize the steep-angle belt conveyor adapting to the change of the slope.

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) An energy-saving end-wall steep-angle conveyor. The innovative structural design makes the tape have no bending resistance and indentation resistance, the running resistance is reduced by 40%, and the running power is reduced by 30% accordingly.

[0014] (2) An energy-saving end-wall steep-angle conveyor. The pressing wheel assembly and the carrying wheel assembly above and below the roller units of the steep-angle belt conveyor run synchronously, and part of the force is borne by the flexible transmission parts connecting the pressing wheel assembly and the carrying wheel assembly, which enables the belt strength of the tape to be reduced by 30%. On the premise of ensuring the conveying performance, a tape with a lower cost can be selected, and at the same time, the risk of the tape being damaged due to excessive force is reduced, and the service life of the tape is extended.

[0015] (3) An energy-saving end-wall large-angle conveyor breaks the verticality limit of traditional conveyors, realizes the "S"-type arrangement of the belt, can use ordinary belts for large-angle conveying, changes the situation that large-angle conveying has relied on special belts in the past, reduces the belt procurement and maintenance costs, and broadens the application range of the conveyor.

[0016] (4) An energy-saving end-wall large-angle conveyor can realize the change of the large-angle belt conveyor with the slope change, has strong environmental adaptability. Through the unit body attitude adjustment cylinder, it can adjust the body attitude in real time according to the undulation of the open-pit mine end-wall slope, ensure the stable operation of the conveyor, reduce the conveying problems caused by terrain changes, and improve the reliability of the equipment.

[0017] (5) An energy-saving end-wall large-angle conveyor. The pressure belt wheel assembly and the load-bearing wheel assembly press the belt into an "S" shape. When running at a large angle of elevation, the frictional force between the material and the belt during the material sliding is converted into the normal pressure of the material on the belt, and the sliding resistance increases significantly, effectively improving the material sliding situation, ensuring the stable conveying of the material during large-angle conveying, reducing material spillage, and improving the conveying efficiency.

[0018] (6) An energy-saving end-wall large-angle conveyor uses a large-angle belt conveyor roller unit body with a length of 12 meters per section, changes the load-bearing wheels on the load-bearing wheel assembly from a series structure to a parallel structure, reduces the tension of the flexible transmission parts on each large-angle belt conveyor roller unit body, effectively reduces the risk of breakage of the flexible transmission parts, reduces the failure rate. This structural optimization improves the overall reliability of the equipment, and reduces the downtime and maintenance costs caused by failures.

[0019] (7) An energy-saving end-wall large-angle conveyor. The load-bearing wheel assemblies and the pressure belt wheel assemblies above and below the large-angle belt conveyor roller unit body run synchronously through flexible transmission parts. The upper pressure belt and the lower load-bearing belt start synchronously when starting, effectively reducing the elastic effect when the belt starts, reducing the tension and the tension stroke, reducing the wear of the belt during the starting process, reducing the requirements for the tensioning device, and further reducing the equipment cost and maintenance difficulty.

[0022] (10) An energy-saving end-wall large-inclination conveyor. Since the belt runs synchronously with the pressure belt wheel assembly and the carrying wheel assembly, a 100% filling rate can be achieved, greatly increasing the conveying capacity of the conveyor, improving production efficiency, and meeting the requirements of large-scale production.

[0023] (11) An energy-saving end-wall large-inclination conveyor. The fuselage of the large-inclination belt conveyor with roller units uses a 12-meter unit. The carrying wheel track and the pressure belt wheel track adopt a whole-profile section without seams. When the carrying wheel assembly and the pressure belt wheel assembly are running, the noise caused by passing through the seams is avoided, which has a noise reduction function, creates a quieter working environment for the operators, and reduces the impact of noise on the surrounding environment.

Through a flexible fuselage design and an adjustable attitude, the conflict between the transportation lines is avoided, and the space utilization rate and transportation safety of the open-pit mine are improved.

[0027] (15) An energy-saving end-wall large-inclination conveyor. It uses an ordinary conveyor belt, which is easy to clean. Compared with the special belt used in traditional large-inclination conveyors, the ordinary conveyor belt has a lower cleaning difficulty, reduces the time and labor costs required for cleaning, and improves the maintenance convenience of the equipment.

[0034] The tail transition section 202 is arranged on the first walking crawler chassis 401, and its main function is to effectively transition between the adjustable tail receiving section 201 and the roller unit body 1 of the steeply inclined belt conveyor to avoid material spillage.

[0038] The roller units of the large-angle belt conveyor body 1 are connected by the body attitude adjustment cylinder 5 to form a body group. The body attitude adjustment cylinder 5 is used to adjust the attitude of the body group to realize the large-angle belt conveyor adapting to the slope change; The number of the roller units of the large-angle belt conveyor body 1 in the body group is determined according to the working conditions; The roller unit body 1 of the large-angle belt conveyor can be evolved for use in a conventional conveyor.

[0039] The working principle of the present invention is as follows: The energy-saving end-wall large-angle conveyor mainly realizes the large-angle conveying of materials through the mutual cooperation of its various components.

[0040] The adjustable tail receiving section 201 is responsible for receiving the incoming materials from the movable belt conveyor. The tail redirecting roller 206 can be adjusted in angle through the belt deviation adjustment cylinder 208 to realize the functions of belt redirection and deviation adjustment, ensuring that the belt 6 maintains a good running state during material receiving. The buffer bed 204, the hopper 205 and the idler 207 are installed above the tail frame 203. The hopper 205 receives the materials. The buffer bed 204 reduces the impact of the materials on the belt 6. The idler 207 plays a supporting role for the belt 6, enabling the materials to fall smoothly on the belt 6. The tail frame 203 is connected to the connecting seat 209 through a pin shaft and an adjustment cylinder 210. The adjustable tail receiving section 201 can be adjusted in angle through the adjustment cylinder 210 to reach the optimal material receiving state.

[0041] Multiple roller units of the large-angle belt conveyor body 1 are connected by the body attitude adjustment cylinder 5 to form a body group, and the body attitude can be adjusted according to the slope change. The body attitude adjustment cylinder 5 can adjust the attitude of the body group in real time according to the undulation of the open-pit mine end-wall slope, enabling the large-angle belt conveyor to adapt to the slope change. By changing the telescopic length of the body attitude adjustment cylinder 5, the relative angles and positions between the roller units of the large-angle belt conveyor body 1 are changed, ensuring that the conveyor can still maintain a good running state in a complex slope environment, and improving the adaptability and reliability of the equipment.

[0042] In each roller unit body 1 of the large angle belt conveyor, the pressure belt wheel steering device 104 and the carrying wheel steering device 101 are respectively connected into a closed loop through the pressure belt wheel track 105 and the carrying wheel track 102. The pressure belt wheel assemblies 106 and the carrying wheel assemblies 103 are connected in series into a closed loop with steel wire ropes or chains and run within their respective tracks. The pressure belt wheel assemblies 106 and the carrying wheel assemblies 103 press the belt 6 into an "S" shape. When running at a large angle for lifting, the frictional force between the material and the belt 6 during the downward sliding of the material is converted into the normal pressure of the material on the belt 6, thereby significantly increasing the downward sliding resistance, effectively improving the downward sliding of the material, and achieving stable large angle conveying. The belt 6, the material, the pressure belt wheel assemblies 106 and the carrying wheel assemblies 103 run synchronously, avoiding problems such as material jamming and leakage, and reducing the wear and scratches of the belt 6.

[0043] The tail transition section 202 is arranged on the first walking crawler chassis 401, and its main function is to effectively 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 the material transportation.

[0044] The head drive transition section 3 provides power for the entire conveyor. The drive device of the head drive transition section 3 drives the belt 6 to run, so that the material is conveyed along with the movement of the belt 6 on the belt 6. The power is transmitted to each component through the belt 6 to achieve continuous conveying of the material.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
