Description

Technical Field

[0001] The invention relates to the field of transportation technology, in particular to loading and unloading equipment for transportation engineering. Background Art

[0002] Transportation engineering is an engineering field that studies the layout and construction of railway, highway, waterway and air transportation infrastructure, vehicle operation engineering, traffic information engineering and control, and transportation operation and management. It is an emerging multidisciplinary discipline that mainly studies the relevant theories, methods and technologies in transportation system engineering, involving the planning, decision-making, construction and management of transportation operation systems and facilities.

[0003] During railway transportation, various items can be loaded onto or unloaded from trains through gantry cranes, rail cranes, belt conveyors, train double-wing loaders, screw conveyors, loaders and other equipment. These loading and unloading equipment play a vital role in railway transportation projects, which can improve the efficiency of cargo loading and unloading and reduce labor intensity. These equipment used for railway transportation loading and unloading operations can be called a type of loading and unloading equipment for transportation projects.

[0004] However, when using the train double-wing loader and unloader type loading and unloading equipment for transportation engineering, the angles of the two belt conveyors installed on the upper end faces can be adjusted through two sets of hydraulic systems according to the height of the train and the transfer truck, so as to connect the train and the transfer truck. When the freight items are placed on the end corners of the belt conveyor, the end corners of the belt conveyor will receive its downward pressure, and this downward pressure will be transmitted to the hydraulic rod of the hydraulic system through the belt conveyor. When the hydraulic rod is subjected to this downward pressure for a long time and multiple times, the material fatigue rate of the hydraulic rod will be accelerated, thereby affecting its service life. In addition, the outer surface of the belt conveyor will inevitably be contaminated with some dust and impurities during the transportation process. If it is not cleaned in time, it will affect the service life of the belt on the belt conveyor. If it is cleaned manually every day, the use process of this equipment is more cumbersome. Therefore, it does not meet the existing needs, and we have proposed a loading and unloading equipment for transportation engineering. Summary of the invention

When the freight items are placed on the end corners of the belt conveyor, the end corners of the belt conveyor will receive its downward pressure, and this downward pressure will be transmitted to the hydraulic rod of the hydraulic system through the belt conveyor. When the hydraulic rod is subjected to this downward pressure for a long time and multiple times, the material fatigue rate of the hydraulic rod will be accelerated, thereby affecting its service life. In addition, the outer surface of the belt conveyor will inevitably be contaminated with some dust and impurities during the transportation process.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] See also Figures 1 to 8 , an embodiment provided by the present invention: a loading and unloading equipment for transportation engineering, comprising a mobile base 1 of a train double-wing loading and unloading machine, a belt conveyor 3 is installed on both sides of the upper end surface of the mobile base 1 of the train double-wing loading and unloading machine, and a hydraulic cylinder 4 for adjusting the angle of the belt conveyor is connected to both sides of the lower end surface of the belt conveyor 3, and a hydraulic cylinder anti-fatigue support mechanism 2 is arranged between the two hydraulic cylinders 4 for adjusting the angle of the belt conveyor, and the hydraulic cylinder anti-fatigue support mechanism 2 comprises a square support sleeve 201, two first arc-shaped head tooth rows 202, a support plate 203, two tooth row storage grooves 204, two second arc-shaped head tooth rows 205 and a synchronous pushing mechanism, and the two first arc-shaped head tooth rows 202 are respectively fixed on both sides of the inside of the square support sleeve 201;

[0035] The bottom end of the support plate 203 is located inside the square support sleeve 201, the two tooth row receiving grooves 204 are respectively located on both sides of the outer surface of the support plate 203, the two second arc-shaped head tooth rows 205 are respectively located inside the two tooth row receiving grooves 204, and the top ends of the tooth heads on the first arc-shaped head tooth row 202 and the second arc-shaped head tooth row 205 are arc-shaped, and the synchronous pushing mechanism can synchronously push the two second arc-shaped head tooth rows 205 outward.

[0036] The synchronous pushing mechanism includes a fixed motor 206, the output shaft of the fixed motor 206 is connected to a threaded rod 207 through a coupling, one side of the outer surface of the threaded rod 207 is connected to a first pushing plate 209 through a threaded structure, and both sides of the threaded rod 207 are provided with an anti-rotation guide rod 208 that movably penetrates the first pushing plate 209, and the anti-rotation guide rod 208 is fixed between the surface facing the mobile base 1 of the train double-wing loader and the inside of the support plate 203; the square support sleeve 201 and the support plate 203 that are slidably connected to each other are respectively connected to the mobile base 1 of the train double-wing loader and the belt conveyor 3 through a rotating shaft, when the belt conveyor angle is adjusted by a hydraulic cylinder 4 according to the height of the train and the transfer truck When adjusting the angle of the belt conveyor 3 installed on the upper end surface of the mobile base 1 of the train double-wing loader, the support plate 203 will move inside the square support sleeve 201 as the belt conveyor 3 rotates. When the angle adjustment of the belt conveyor 3 is completed, the fixed motor 206 will automatically start, and the fixed motor 206 can drive the threaded rod 207 connected thereto to rotate. Since the first push plate 209 connected to the threaded rod 207 through the threaded structure is penetrated by two anti-rotation guide rods 208, the first push plate 209 itself cannot rotate. When the threaded rod 207 rotates, the first push plate 209 that cannot rotate itself will move along the threaded rod 207 driven by the threaded structure.

[0037] A second pushing plate 211 is provided on both sides of the first pushing plate 209. The two second pushing plates 211 are respectively fixed between the two second arc-shaped head tooth rows 205, and the surface of the first pushing plate 209 facing the second pushing plate 211 is an inclined surface 210; at this time, the first pushing plate 209 is driven by the fixed motor 206 to move toward the direction of the second pushing plate 211. As the first pushing plate 209 moves, the inclined surface 210 on the outer surface of the first pushing plate 209 will contact the second pushing plate 211 and When the second pushing plate 211 is pushed, it will move outwards. During the outward movement of the second pushing plate 211, the second arc-shaped head tooth row 205 fixed thereto will move outwards together. The tooth heads on the outward-moving second arc-shaped head tooth row 205 will mesh with the tooth heads on the first arc-shaped head tooth row 202 fixed on the inner wall of the square support sleeve 201. The meshing second arc-shaped head tooth row 205 and the first arc-shaped head tooth row 202 can fix the support plate 203 to the square support sleeve 201. The fixed square support sleeve 201 and the support plate 203 can form a support point, through which the downward pressure generated by the placement of goods on the hydraulic cylinder 4 for adjusting the angle of the belt conveyor can be shared, so that the bearing load of the hydraulic cylinder 4 for adjusting the angle of the belt conveyor can be reduced, and the stress borne by its structural components can be reduced, thereby slowing down the material fatigue rate and extending the service life of the hydraulic cylinder 4 for adjusting the angle of the belt conveyor. The support point formed by the fixed square support sleeve 201 and the support plate 203 provides a stable fulcrum for the belt conveyor. During the conveying process, especially when conveying heavier or larger goods, this support point can prevent the belt conveyor 3 from deflecting or overturning due to uneven force or vibration, thereby improving the stability of the equipment operation. In addition, this support point can also share part of the load borne by the belt conveyor 3 itself, and the wear of the components of the belt conveyor 3 will be relatively reduced, thereby reducing the frequency and cost of maintenance and replacement of components. The above technical solution can thereby increase the service life of the hydraulic cylinder 4 for adjusting the angle of the belt conveyor;

[0038] The synchronous pushing mechanism pushes the two second arc-shaped head tooth rows 205 upward synchronously by rotating the threaded rod 207. After the square support sleeve 201 and the support plate 203 are fixed, the threaded rod 207 and the first pushing plate 209 are still in a threaded connection state. This threaded connection can prevent the first pushing plate 209 from moving due to the downward pressure generated by placing the goods, which eventually leads to the loosening of the fixation between the support plate 203 and the square support sleeve 201.

[0039] Since the top ends of the teeth on the second arc-shaped head tooth row 205 and the first arc-shaped head tooth row 202 are both arc-shaped, when the second arc-shaped head tooth row 205 is pushed outward by the synchronous pushing mechanism, the teeth on the second arc-shaped head tooth row 205 directly collide with the teeth on the first arc-shaped head tooth row 202, and will also be staggered from each other under the push of the arc surface. This structure can ensure that the second arc-shaped head tooth row 205 can engage with the first arc-shaped head tooth row 202 to fix the square support sleeve 201 and the support plate 203.

[0040] A reset rod 212 is fixedly provided on both sides of the opposite surfaces of the two second arc-shaped head tooth rows 205, and a reset sleeve 213 is sleeved on one side of the outer surface of the reset rod 212, and a reset spring 214 is connected to the surface of the reset sleeve 213 facing the nearest second arc-shaped head tooth row 205; when the second arc-shaped head tooth row 205 is pushed outward, the reset rod 212 fixed thereto and the reset sleeve 213 fixedly sleeved on the outer surface of the reset rod 212 will move outward together, and the reset sleeve 213 moving outward will squeeze the reset spring 214 connected thereto. When it is necessary to adjust the angle of the belt conveyor 3 again, the threaded rod 207 is first rotated in the opposite direction by the fixed motor 206 to drive the first pushing plate 209 to move toward its original position. When the first pushing plate 209 moves toward its original position, the reaction force of the squeezed reset spring 214 can gradually push the second arc-shaped head tooth row 205 back to its original position, thereby releasing the fixation between the support plate 203 and the square support sleeve 201.

[0041] A concave guide sleeve 215 slidably connected to the square support sleeve 201 is fixedly provided on both sides of the outer surface of the support plate 203, and an anti-drop rod 216 fixed to the outer surface of the square support sleeve 201 is provided on one side of the concave guide sleeve 215, and an anti-drop sleeve 217 is movably provided on one side of the outer surface of the anti-drop rod 216, and the anti-drop sleeve 217 is fixed to the surface of the concave guide sleeve 215 facing the nearest concave guide sleeve 215; the concave guide sleeve 215 fixed to the outer surface of the support plate 203 and slidably connected to the square support sleeve 201 can prevent the support plate 203 from shaking during the movement, thereby ensuring the stability of the support plate 203, and the anti-drop rod 216 and the anti-drop sleeve 217 can prevent the support plate 203 from completely leaving the inside of the square support sleeve 201.

[0042] A conveyor belt self-cleaning and maintenance mechanism is fixedly installed inside the mobile base 1 of the train double-wing loader. The conveyor belt self-cleaning and maintenance mechanism includes an electric lifting platform 5, a metal shell 6, a cleaning sponge 7, a medicine adding device 9, a high-concentration protective coating 10, a water source storage tank 11, multiple spray heads 12, a water supply pipe 13, a stirring shaft 14, and a water flow transmission mechanism.

[0044] A plurality of spray heads 12 are fixedly mounted on both sides of the upper end surface of the metal housing 6, and the spray heads 12 are connected to the interior of the water source storage tank 11;

[0045] The water supply pipe 13 is connected to the inside of the water source storage tank 11, the water flow transmission mechanism is located below the water outlet of the water supply pipe 13, the stirring shaft 14 is located inside the water supply pipe 13, and the water flow transmission mechanism can drive the stirring shaft 14 to rotate; when the belt conveyor 3 needs to be cleaned at the end of a day's work, the belt conveyor 3 is started first to ensure that the belt on the belt conveyor 3 is in a state of continuous movement;

[0046] When the belt conveyor 3 is started, the faucet is connected through the water supply pipe 13, and then the faucet is opened to pour water into the water source storage tank 11. Then, the water source located inside the water source storage tank 11 is extracted through the spray head 12, and it is sprayed on the outer surface of the continuously moving belt conveyor 3. When the spray head 12 starts to spray water, the metal shell 6 and the cleaning sponge 7 are moved upward by the electric lifting platform 5. When the two ends of the cleaning sponge 7 are respectively in contact with the belts on the two belt conveyors 3, they can be cleaned. After the cleaning sponge 7 has rubbed with the belt conveyor 3 for five minutes, the cleaning operation of the belt on the belt conveyor 3 is completed. Then, the metal shell 6 and the cleaning sponge 7 are moved downward by the electric lifting platform 5 and the connection between the water supply pipe 13 and the faucet can be disconnected.

[0047] The conveyor belt self-cleaning and maintenance mechanism also includes a strip-shaped opening 8, and a drug adding device 9 is fixedly installed at the middle position of the inner wall at the lower end of the strip-shaped opening 8; the drug adding device 9 can be installed through the strip-shaped opening 8, and when the high-concentration protective coating 10 inside the drug adding device 9 is used up, the staff can contact the drug adding device 9 through the strip-shaped opening 8 and replenish the high-concentration protective coating 10 inside the drug adding device 9;

[0048] When the mobile base 1 of the train double-wing loader is used continuously for ten days, after the cleaning operation on the tenth day is completed, the high-concentration protective coating 10 is added to the inside of the water source storage tank 11 through the dosing device 9.

[0049] The water flow transmission mechanism includes a small waterwheel 21, the axis of the small waterwheel 21 is connected to the waterwheel shaft 20, both ends of the waterwheel shaft 20 are located inside the metal shell 6, and the waterwheel shaft 20 located inside the metal shell 6 is connected to the metal shell 6 through a roller bearing; a fourth bevel gear 19 is provided on a fixed sleeve on one side of the outer surface of the waterwheel shaft 20, and the fourth bevel gear 19 is meshed with a third bevel gear 18, and the axis of the third bevel gear 18 is connected to a gear transmission shaft 17, and a second bevel gear 16 is provided on the lower side of the outer surface of the gear transmission shaft 17.

The rotating small waterwheel 21 can drive the waterwheel shaft 20 connected to the axis of the small waterwheel 21 and the fourth bevel gear 19 fixedly sleeved on the outer surface of the waterwheel shaft 20 to rotate. The rotating fourth bevel gear 19 can drive the third bevel gear 18 meshing therewith and the gear transmission shaft 17 connected to the axis of the third bevel gear 18 to rotate.

After the water source mixed with the high-concentration protective coating 10 is sprayed onto the outer surface of the belt of the belt conveyor 3, it will be smoothed by the cleaning sponge 7. When the outer surface of the belt of the belt conveyor 3 is completely coated with a layer of high-concentration protective coating 10, close the spray head 12, the dosing device 9, disconnect the water supply pipe 13 from the faucet, and move the metal shell 6 downward, and then place the device for a period of time until the water source mixed with the high-concentration protective coating 10 sprayed on the outer surface of the belt conveyor 3 is smoothed.
