Description

Technical Field

[0001] This utility model relates to the field of maintenance platform technology, and in particular to a liftable maintenance platform for rapid loading stations. Background Technology

[0002] Rail trains have the advantages of large loading capacity and fast transportation, so they are often used as a means of transportation for large-volume cargo transportation (such as long-distance mineral transportation). Since rail trains have a large number of carriages and are therefore relatively long, loading stations are often set up to facilitate rapid loading of materials. Rail trains move through loading stations to load materials.

[0003] Currently, loading stations often have multiple platforms around their loading mechanisms. The inventor discovered that these platforms are connected by stairs. To reduce climbing time, liftable maintenance platforms are often installed at the edges of the platforms. To improve safety, these maintenance platforms are often equipped with railings, and gates are often installed between the maintenance platforms and the main platforms. Since these gates rotate horizontally, they require a large amount of space to open and close. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rapid loading and unloading station maintenance platform.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a liftable maintenance platform for a rapid loading station, including a loading mechanism. The loading mechanism includes a multi-layer platform, with feeding hoppers arranged from top to bottom. The feeding hoppers are fixedly installed between the platform and the platform. Multiple metering hoppers are connected below the feeding hoppers, and the metering hoppers are detachably installed from the feeding hoppers. A weighing component is detachably installed at the bottom of the metering hoppers. A collecting hopper is arranged below the weighing component, and the collecting hopper is detachably installed from the platform. A discharge valve is arranged below the collecting hopper. A rain shelter can be installed on the uppermost platform to protect against rain. A canopy blocks the top of the feeding hopper. A conveying module is installed on the side of the loading mechanism. The conveying module is inclined. The core of the conveying module is a conveyor belt, and a protective corridor is installed on the surface of the conveyor belt. The upper end of the protective corridor is between the rain shelter and the platform. The conveyor belt transports the material into the feeding hopper. A lifting component is set on the side of the loading mechanism. A traction component is installed at the upper end of the loading mechanism. The lifting component includes a maintenance platform that can move in the vertical direction. The traction component drives the maintenance platform to move in the vertical direction. A lifting door that can be raised and lowered in the vertical direction is set on the maintenance platform.

[0006] The effects achieved by the above components are as follows: The loading mechanism is set above the rails, and the loading train moves along the rails to the area below the loading mechanism. The material on the side of the rails is transported at an angle along the conveyor belt in the conveying module to the feeding hopper. The material enters the weighing component from the feeding hopper along the metering hopper for weighing (the weighing component can be a digital weighing meter or a quantitative feeding valve; since these are all conventional equipment, their principles will not be elaborated here). The metering hopper allows for rapid material distribution and conveying. The metered material is conveyed to the collection hopper, and finally, the discharge valve (which can be electrically or hydraulically driven) is opened to pour the material into the carriage. The train then moves slowly to evenly load the material into the carriage. When maintenance is required on the various components of the loading mechanism, maintenance personnel need to go to each platform and use the traction component to pull the maintenance platform vertically to transport personnel or materials. The lifting door allows the door to open and close vertically, and the opening and closing of the lifting door does not occupy the surface space of the maintenance platform, thus saving space.

[0007] Preferably, the loading mechanism has a detachable track on its side, and the maintenance platform has a track groove on its side. The maintenance platform slides along the track using the track groove. A diagonal bracing steel structure is provided between the track and the loading mechanism to reinforce the connection between the track and the loading mechanism.

[0008] The above components achieve the following effects: the track is vertically and detachably installed on the side of the platform via bolts, and the two ends of the diagonal bracing steel structure are detachably installed between the platform and the track, respectively. The diagonal bracing steel structure can improve the stability of the track, and the maintenance platform can be adjusted along the track direction to ensure relatively stable movement of the maintenance platform.

[0009] Preferably, a guardrail is installed on the upper part of the inspection platform, and a sling is fixedly connected to the guardrail. The traction component pulls the inspection platform with the help of the sling. The traction component includes a top frame, which is fixed to one side of the top of the loading mechanism. A winch is installed on the top frame. The winch drives a winding wheel to rotate, and the winding wheel winds a steel cable. The steel cable pulls the sling upward, thereby raising the inspection platform. A diagonal brace is provided between the top frame and the loading mechanism to reinforce the connection between the top frame and the loading mechanism. A rain shelter is detachably installed on the upper part of the top frame.

[0010] The effects achieved by the above components are as follows: the protective railing on the surface of the maintenance platform can improve the safety of the maintenance platform. By controlling the winch (which can be remotely controlled or controlled by laying a circuit switch; it should be noted that winch control is a conventional technical means, so its principle, cable routing and control process will not be described in detail here), the winch drives the winding wheel to rotate. The winding wheel pulls the sling by winding the steel cable, thereby controlling the vertical position of the maintenance platform. The rain shelter can protect the winch.

[0011] Preferably, the bottom of the maintenance platform is slidably connected to a hook, the hook is hooked to the bottom of the lifting door, and a reset component is fixedly connected between the hook and the maintenance platform, wherein a rope is fixedly connected to the surface of the hook.

[0012] The aforementioned components achieve the following effects: The hook normally holds the lifting door. When the lifting door needs to be opened, pulling the rope pulls the hook, causing it to squeeze the reset component away from below the lifting door. This allows the lifting door to fall freely without obstruction, creating a gap in the guardrail. Equipment or personnel can then be transported through this gap. A stepped platform is provided on the ground relative to the maintenance platform (the lifting platform will not lower to contact the ground; the lowest level of the platform's lowering provides a clearance for the lifting door to descend). When the lifting door needs to be closed, manually pulling it upwards moves the door upwards, dislodging the hook. Under the reset force of the reset component, the hook holds the lifting door in place, ensuring it remains closed.

[0013] Preferably, the reset component includes a slide groove formed at the bottom of the inspection platform, wherein the hook slides inside the slide groove by means of a dovetail slider, a guide rod is slidably installed inside the dovetail slider, the two ends of the guide rod are fixed to the slide groove, and a spring is sleeved on the surface of the guide rod, the two ends of the spring are fixedly connected to the dovetail slider and the slide groove respectively, the upper end of the hook is a flat surface supporting the bottom of the lifting door, and the bottom of the hook is provided with an inclined surface. When the lifting door is lifted upward in the lowered state, the bottom crossbar of the lifting door squeezes the inclined surface and pushes open the hook.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, the lifting door allows the door to open and close vertically, thus saving space by not occupying the surface space of the maintenance platform when opening and closing the lifting door. Attached Figure Description

[0024] like Figure 1-2As shown, the rapid loading station's liftable maintenance platform includes a loading mechanism 1, which comprises a multi-level platform 11. From top to bottom, each platform 11 has a feeding hopper 12, which is fixedly installed to the platform 11. Multiple metering hoppers 13 are connected below the feeding hoppers 12, and these hoppers are detachably installed from the feeding hoppers 12. A weighing component 14 is detachably installed at the bottom of each metering hopper 13. A collecting hopper 15 is located below the weighing component 14, and it is detachably installed from the platform 11. A discharge valve 16 is located below the collecting hopper 15. The uppermost platform 1... A rain shelter can be installed on the loading mechanism 1, covering the top of the feed hopper 12. A conveying module 2 is provided on the side of the loading mechanism 1. The conveying module 2 is inclined, and the core of the conveying module 2 is a conveyor belt. A protective corridor is installed on the surface of the conveyor belt, and the upper end of the protective corridor is between the rain shelter and the platform 11. The conveyor belt transports the material into the feed hopper 12. A lifting component 3 is provided on the side of the loading mechanism 1. A traction component 4 is installed at the upper end of the loading mechanism 1. The lifting component 3 includes a maintenance platform 31 that can move in the vertical direction. The traction component 4 drives the maintenance platform 31 to move in the vertical direction. The repair platform 31 is equipped with a vertically movable lifting door 35. The loading mechanism 1 is located above the rails. The loading train moves along the rails to the area below the loading mechanism 1. The material on the side of the rails is transported at an angle along the conveyor belt in the conveyor module 2 into the feeding hopper 12. The material from the feeding hopper 12 enters the weighing component 14 via the metering hopper 13 for weighing (the weighing component 14 can be a digital weighing instrument or a quantitative feeding valve; since these are all conventional devices, their principles will not be elaborated here). The metering hopper 13 allows for rapid material distribution and conveying. The metered material is then transported to... In the hopper 15, the discharge valve 16 is finally opened (the discharge valve 16 can be electrically driven or hydraulically driven to open and close) to pour the material into the carriage. Then the train is driven slowly to load the material evenly into the carriage. When it is necessary to inspect the components of the loading mechanism 1, the maintenance personnel need to go to each platform 11 and use the traction component to pull the inspection platform 31 to move vertically to transport personnel or materials. The lifting door 35 can be opened and closed vertically, and the lifting door 35 does not occupy the surface space of the inspection platform 31 when it is opened and closed, thus saving space.

[0025] Example 1, referring to Figure 1-7The loading mechanism 1 has a detachable track 39 on its side. The maintenance platform 31 has a track 39 groove 34 on its side. The maintenance platform 31 slides along the track 39 using the track 39 groove 34. A diagonal bracing steel structure is provided between the track 39 and the loading mechanism 1 to reinforce the connection between the track 39 and the loading mechanism 1. The track 39 is vertically and detachably installed on the side of the platform 11 by bolts. The two ends of the diagonal bracing steel structure are detachably installed between the platform 11 and the track 39, respectively. The diagonal bracing steel structure can improve the stability of the track 39. The maintenance platform 31 can be adjusted along the direction of the track 39 to ensure relatively stable movement of the maintenance platform 31. A guardrail 32 is installed on the upper end of the maintenance platform 31. A sling 33 is fixedly connected to the guardrail 32. The traction component 4 pulls the maintenance platform 31 with the sling 33. The traction component 4 includes a top frame 41, which is fixed to the loading mechanism. 1. On one side of the top, a winch 42 is installed on the top frame 41. The winch 42 drives the winding wheel 43 to rotate. The winding wheel 43 winds a steel cable, which pulls the sling 33 upward, thereby raising the maintenance platform 31. A diagonal brace 44 is provided between the top frame 41 and the loading mechanism 1 to reinforce the connection between the top frame 41 and the loading mechanism 1. A rain shelter is detachably installed on the upper end of the top frame 41. The guardrail 32 on the surface of the maintenance platform 31 can improve the safety of the maintenance platform 31. By controlling the winch 42 (which can be controlled by remote control or by laying a switch; it should be noted that the winch 42 control is a conventional technical means, so its principle, cable routing and control process will not be described in detail here), the winch 42 drives the winding wheel 43 to rotate. The winding wheel 43 winds the sling 33 through the steel cable, thereby controlling the vertical position of the maintenance platform 31. The rain shelter can protect the winch 42.

[0026] Reference Figure 1-7The bottom of the maintenance platform 31 is slidably connected to a hook 36, which hooks onto the bottom of the lifting door 35. A reset component 37 is fixedly connected between the hook 36 and the maintenance platform 31. A rope 38 is fixedly connected to the surface of the hook 36. Normally, the hook 36 supports the lifting door 35. When the lifting door 35 needs to be opened, the rope 38 is pulled, causing the hook 36 to squeeze the reset component 37 and disengage from below the lifting door 35. This allows the lifting door 35 to fall freely without obstruction, creating a gap in the guardrail 32. Equipment or personnel can then be transported through this gap. A stepped platform is provided on the ground relative to the maintenance platform 31 (the lifting platform will not lower to contact the ground; that is, the lowest stage of the lifting platform's lowering provides a clearance for the lifting door 35 to descend). When it is necessary to close the lifting door 35, manually pull the lifting door 35 upward to make the lifting door 35 move upward and push open the hook 36. The hook 36 is then supported under the resetting force of the reset component 37 to ensure that the lifting door 35 is closed. The reset component 37 includes a slide groove opened at the bottom of the inspection platform 31. The hook 36 slides in the slide groove with the help of the dovetail slider. A guide rod is slidably installed inside the dovetail slider. The two ends of the guide rod are fixed to the slide groove. The surface of the guide rod is covered with a spring. The two ends of the spring are fixedly connected to the dovetail slider and the slide groove, respectively. The upper end of the hook 36 is a flat surface that supports the bottom of the lifting door 35. The bottom of the hook 36 is provided with an inclined surface. When the lifting door 35 is lifted upward in the lowered state, the bottom crossbar of the lifting door 35 squeezes the inclined surface and pushes open the hook 36.

[0027] Working principle: The loading mechanism 1 is located above the rails. The loading train moves along the rails to below the loading mechanism 1. Material on the side of the rails is transported at an angle along the conveyor belt in the conveyor module 2 into the feed hopper 12. The material from the feed hopper 12 enters the weighing component 14 through the metering hopper 13 for weighing. The metering hopper 13 allows for rapid material distribution and conveying. The metered material is then transported to the collection hopper 15. Finally, the discharge valve 16 is opened to pour the material into the carriage. The train then moves slowly to evenly load the material into the carriage. When it is necessary to target the various parts of the loading mechanism 1... When inspecting components, maintenance personnel need to go to each platform 11. The maintenance platform 31 is pulled vertically by a traction component to transport personnel or materials. The lifting door 35 allows for vertical opening and closing, saving space by not occupying surface space on the maintenance platform 31. The track 39 is vertically and detachably bolted to the side of the platform 11. The diagonal bracing steel structure is detachably installed at both ends to the platform 11 and the track 39, respectively. The diagonal bracing steel structure improves the stability of the track 39. The maintenance platform 31 moves along the track 39... The position can be adjusted in 9 directions to ensure the relatively stable movement of the maintenance platform 31. The protective railing 32 on the surface of the maintenance platform 31 can improve the safety of the maintenance platform 31. By controlling the winch 42, the winch 42 drives the winding wheel 43 to rotate. The winding wheel 43 pulls the sling 33 through the steel cable, thereby controlling the vertical position of the maintenance platform 31. The rain canopy can protect the winch 42. The hook 36 normally supports the lifting door 35. When it is necessary to open the lifting door 35, the rope 38 is pulled. The rope 38 pulls the hook 36, causing the hook 36 to squeeze the reset component 37 to disengage from the lifting door. Below 35, the lifting door 35 is unobstructed and falls freely, thus creating a gap in the guardrail 32. At this time, equipment or personnel can be transported through the gap. A stepped platform is set on the ground relative to the maintenance platform 31 (the lifting platform will not be lowered to contact the ground, that is, the lowest stage of the lifting platform is lowered to leave a landing gap for the lifting door 35). When it is necessary to close the lifting door 35, manually pull the lifting door 35 upward to make the lifting door 35 move upward and push open the hook 36. The hook 36 is then supported below the lifting door 35 by the resetting force of the reset component 37 to ensure that the lifting door 35 is closed.
