DETAILED DESCRIPTION

[0029] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0030] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Figures 1-9 A multifunctional coal unloading and coal chute structure comprises a coal chute 1 and a coal unloading assembly 3 arranged at one side of the opening of the coal chute 1, the coal unloading assembly 3 is used for lifting the end of the container 2 away from the coal chute 1, two groups of support assemblies 4 are arranged in the coal chute 1 and are used for preventing the container 2 from sliding after tilting, and the support assemblies 4 are adjusted in height by the lifting assemblies 5 according to the height of the container 2. A support net 101 is fixed to the inner bottom of the coal chute 1, and a coal unloading passage 102 is arranged obliquely at the bottom of the coal chute 1. The coal unloading assembly 3 comprises two groups of traction ropes 301 used for pulling the container 2 and winding rollers 304 used for winding the traction ropes 301, one end of the traction rope 301 is wound on the surface of the winding roller 304, the other end of the traction rope 301 is fixed with a hook 302, the two winding rollers 304 are rotatably arranged on the inner wall of the shell 303 through a connecting shaft, a through hole is formed in the surface of the shell 303 for the traction rope 301 to extend out, the shell 303 is fixed to one side of the coal chute 1, and a driving motor is fixed to the side of the shell 303 and used for driving the connecting shaft and the winding roller 304 to rotate.

[0031] It can be understood that after the container 2 is transported into the coal chute 1 with the door on one side opened, the one end of the traction rope 301 is connected to the side of the container 2 away from the coal chute 1 through the hook 302 (the corner part of the container 2 is provided with a cast iron corner with a hole on the surface, which is a prior structure), the driving motor is operated to drive the two winding rollers 304 to rotate, thereby winding the traction rope 301, the traction rope 301 pulls the side of the container 2 to be lifted, the container 2 is tilted, the coal in the container 2 is quickly discharged into the coal chute 1, and the purpose of quick coal unloading is achieved; the support assembly 4 is arranged to abut against the side of the container 2 in the coal chute 1, thereby preventing the container 2 from sliding off the flat wagon (not shown in the drawing) after tilting and causing an accident.

[0032] Specifically, the support assembly 4 comprises a support cylinder 401 used for abutting against the bottom of the container 2, the support cylinder 401 is fixed to the surface of a mounting plate 404, the mounting plate 404 vertically slides on the inner wall of the coal chute 1 through a track, and the support assembly 4 comprises two groups of support assemblies 4 and is symmetrically arranged on the inner side of the coal chute 1.

[0033] It can be understood that, since all the shackles of the container 2 need to be opened when lifting the container 2, the container 2 is prone to sliding down after the container 2 is tilted, resulting in the container 2 falling off the flatbed truck, therefore, the support cylinder 401 is arranged to abut against the reinforcing beam at the bottom of the container 2, which can prevent the container 2 from sliding down after the container 2 is tilted; by arranging two groups of support assemblies 4, the two support cylinders 401 symmetrically abut against the container 2, so that the container 2 is kept balanced.

[0034] Specifically, the support assembly 4 further comprises a support plate 402 for supporting the middle part of the container 2, the support plate 402 is rotatable on the surface of the support cylinder 401 through a connecting arm 403, the upper end of the connecting arm 403 is fixed on the surface of the support plate 402, a limiting groove 405 for limiting the swing angle of the connecting arm 403 is arranged on the surface of a mounting plate 404, the limiting groove 405 is arc-shaped, one end of the support plate 402 facing the mounting plate 404 is slidably arranged in the limiting groove 405, the arc-shaped limiting groove 405 is concentrically arranged with the support cylinder 401, a tension spring 406 for driving the support plate 402 to reset is fixed on the upper end of the connecting arm 403, and the other end of the tension spring 406 is fixed on the surface of the mounting plate 404.

[0035] It can be understood that, since the support cylinder 401 supports the reinforcing beam at the bottom of the container 2, the contact area is small, and the container 2 has a probability of being separated from the support cylinder 401 after the container 2 is tilted, resulting in the container 2 sliding down; in order to prevent the container 2 from sliding down after the container 2 is tilted, the support plate 402 is arranged to further support the container 2, when the container 2 is tilted, the bottom of the container 2 abuts against the surface of the support cylinder 401, and at the same time, the support plate 402 slides in the limiting groove 405, so that the support plate 402 can adjust the position following the angle of the container 2, since the limiting groove 405 is a closed structure, when the container 2 is accidentally separated from the support cylinder 401, the container 2 drives the support plate 402 to slide to the root of the limiting groove 405, thereby limiting the position of the support plate 402, so that the support plate 402 can intercept the container 2, avoiding the container 2 from completely separating from the surface of the flatbed truck, thereby the support plate 402 further supports and protects the container 2; by arranging the tension spring 406, the support plate 402 can be reset after the container 2 is separated from the support plate 402, by arranging the connecting arm 403, the rotation of the support plate 402 is centered on the support cylinder 401, thereby improving the stability and the supporting strength of the support plate 402.

[0036] Specifically, in the normal state, the connecting arm 403 is in an inclined state, the distance between the support plate 402 and the opening of the coal chute 1 is less than the distance between the support cylinder 401 and the opening of the coal chute 1, and a contact sensor is arranged on the surface of the support plate 402. A camera 8 is fixed to the inner wall of the coal chute 1 away from the opening, and the camera 8 and the contact sensor are electrically connected with the mobile terminal.

[0037] It can be understood that in the normal state, the pull spring 406 drives the support plate 402 to be located at one end of the limiting groove 405 close to the opening of the coal chute 1, when the container 2 enters the coal chute 1, the container 2 first contacts the support plate 402 and triggers the contact sensor to send a signal, so that the mobile terminal sends a reminder, so that the flat car stops in time, at the same time, the support plate 402 can slide in the limiting groove 405, leaving a margin for the inertial movement of the flat car and the container 2; by setting the camera 8, the movement of the container 2 in the coal chute 1 can be observed.

[0038] Specifically, the lifting assembly 5 has two groups, and drives two groups of support assemblies 4 to lift, the lifting assembly 5 includes a lifting frame 501 sliding on the surface of a guide rod 502 and an infrared opposite transmission sensor 503 arranged on the side of the lifting frame 501 facing the container 2, the guide rod 502 is fixed at the opening side of the coal chute 1, the mounting plate 404 is fixed on the surface of the lifting frame 501, the lifting frame 501 is driven to lift by a hydraulic rod 504, the hydraulic rod 504 is located at the lower end of the lifting frame 501, and the lower end of the hydraulic rod 504 is fixed at the opening side of the coal chute 1.

[0039] It can be understood that due to the deviation of the height of different types of flat cars, the height of the container 2 is deviated, therefore, the lifting assembly 5 is arranged, in the normal state, the hydraulic rod 504 drives the lifting frame 501 and the support assembly 4 to rise to the highest position of the guide rod 502, when the container 2 enters the coal chute 1, the lifting frame 501 and the support assembly 4 are driven by the hydraulic rod 504 to slide downward, when the infrared opposite transmission sensor 503 is blocked by the container 2, the lifting frame 501 and the support assembly 4 stop, so that the support cylinder 401 and the reinforced beam at the bottom of the container 2 are kept at the same height, which is convenient for contacting the container 2, and can be adapted to different types of flat cars.

[0040] Specifically, the support plate 402 is provided with a top pressing assembly 6 for contacting the door plate of the container 2, the top pressing assembly 6 includes a push arm 601 rotating in the middle of the support plate 402 through a rotating shaft, the end of the push arm 601 away from the support plate 402 is hammer-shaped, a torsional spring 602 for driving the push arm 601 to rotate towards the container 2 is sleeved on the surface of the rotating shaft, and the rotating shaft is fixed in the middle of the support plate 402.

[0041] It can be understood that, since the door panel of the container 2 needs to be opened before the container 2 enters the coal chute 1 to facilitate the unloading of coal, the top pressing assembly 6 is arranged to drive the push arm 601 to rotate towards the container 2, so that the push arm 601 pushes the door panel against the side of the container 2, keeping the door panel in an open state to facilitate the unloading of coal. The top pressing assembly 6 is arranged on the surface of the support plate 402, so that the top pressing assembly 6 can rotate with the support plate 402, and the push arm 601 can keep abutting against the door panel.

[0042] Specifically, the top of the lifting frame 501 is provided with a knocking assembly 7 for knocking the container 2. The knocking assembly 7 includes a knocking hammer 701 rotating on the surface of the lifting frame 501 through a rotating shaft, and a toothed plate 702 for driving the knocking hammer 701 to swing. The rotating shaft is located at the upper end of the knocking hammer 701, and the lower end of the knocking hammer 701 is provided with a hammer head for knocking the container 2. A push plate is fixed to the upper end of the knocking hammer 701. The toothed plate 702 vertically slides on the surface of the lifting frame 501. The upper end of the toothed plate 702 is fixed with an electric push rod 703 for driving the toothed plate 702 to reciprocatingly lift and lower. The electric push rod 703 is fixed to the upper end of the lifting frame 501. The surface of the toothed plate 702 is provided with a plurality of tooth blocks matched with the push plate.

[0043] It can be understood that the knocking hammer 701 swings through the rotating shaft, so that the hammer head at the lower end of the knocking hammer 701 knocks the container 2 to produce vibration, which facilitates the vibration and falling of the sticky coal blocks in the container 2, and improves the unloading effect. The electric push rod 703 drives the toothed plate 702 to reciprocatingly lift and lower, so that the tooth blocks of the toothed plate 702 drive the push plate at the upper end of the knocking hammer 701 to rotate, thereby driving the knocking hammer 701 to swing. The cooperation of the plurality of tooth blocks and the push plate can improve the swing frequency of the knocking hammer 701, thereby increasing the knocking times of the knocking hammer 701 on the container 2. The upper surface and the lower surface of the tooth block are both inclined surfaces, which can drive the knocking hammer 701 to swing during the reciprocating movement of the toothed plate 702. When the tooth block abuts against the surface of the push plate, the knocking hammer 701 rotates through the rotating shaft. When the tooth block is separated from the push plate, the lower end of the knocking hammer 701 has not yet contacted the container 2, but continues to swing by inertia until it collides with the container 2 to produce vibration.

[0044] In the application, the container 2 is transported into the coal chute 1 by the flatbed truck. Before transportation, the container 2 door is opened, the driver observes the camera 8 view angle through the mobile terminal, at the same time, the push arm 601 pushes the door to abut against the side of the container 2, and keeps the door open. When the container 2 moves beyond the infrared opposite sensor 503, the lifting frame 501 and the support assembly 4 are driven by the hydraulic rod 504 to slide downward. When the infrared opposite sensor 503 is blocked by the container 2, a signal is sent to stop the lifting frame 501 and the support assembly 4, so that the support cylinder 401 keeps the same height with the reinforced beam at the bottom of the container 2, and the container 2 continues to move into the coal chute 1. The container 2 first abuts against the support plate 402, and triggers the contact sensor to send a signal to the mobile terminal to send a reminder. The driver stops the flatbed truck in time. At the same time, the support plate 402 can slide in the limiting groove 405 to leave a margin for the movement of the truck and the container 2. The camera 8 is arranged to facilitate the observation of the movement of the container 2 in the coal chute 1. When the container 2 is moved to the position, the worker connects one end of the traction rope 301 to the side of the container 2 away from the coal chute 1 through the hook 302, and then drives the motor to rotate the two winding rollers 304 to wind the traction rope 301, so that the traction rope 301 pulls one side of the container 2 to lift, and the container 2 is inclined, so that the coal in the container 2 is quickly discharged into the coal chute 1, and the purpose of quick coal unloading is achieved. Under the action of the support cylinder 401, the reinforced beam at the bottom of the container 2 is abutted, which can prevent the container 2 from sliding after the container 2 is inclined. The support plate 402 further supports the container 2. When the container 2 is inclined, the bottom of the container 2 abuts against the surface of the support cylinder 401, and at the same time, the support plate 402 slides in the limiting groove 405, so that the support plate 402 can adjust the position according to the angle of the container 2. Since the limiting groove 405 is a closed structure, when the container 2 is accidentally separated from the support cylinder 401, the container 2 drives the support plate 402 to slide to the root of the limiting groove 405 to limit the position of the support plate 402, so that the support plate 402 further supports and protects the container 2. After the coal is unloaded, the tooth plate 702 is driven by the electric push rod 703 to reciprocate up and down, the tooth block of the tooth plate 702 drives the lever of the knocking hammer 701 to rotate, so that the knocking hammer 701 swings, and the knocking hammer 701 swings through the rotating shaft to knock the container 2, so that the container 2 vibrates, the adhered coal in the container 2 is shaken off, and the unloading effect is improved.
