Abstract
Description
Technical Field
[0001] This application relates to the field of building material transportation technology, specifically to a rail-mounted unloading platform. Background Technology
[0002] In construction sites, traditional unloading platforms are mostly electrically driven, which is efficient, but its application is limited in scenarios where there is no power supply or where precise control is required.
[0003] In manual unloading platforms, the stopping of transport trolleys is usually controlled manually or by adding a limiting structure. Manual control is labor-intensive and may cause safety accidents, while adding a limiting structure can easily cause the transport trolley to bounce back, making it difficult for the transport trolley to stop accurately at the unloading station. Utility Model Content
[0004] This application aims to solve one of the technical problems in the background art by providing a rail-mounted unloading platform.
[0005] This application is achieved through the following technical solution:
[0006] A rail-mounted unloading platform, comprising:
[0007] Supporting framework;
[0008] The track is connected to the support frame;
[0009] A transport trolley, which cooperates with the track;
[0010] A first buffer assembly is connected to the support frame and located on one side of the track length direction. The first buffer assembly has a buffer portion for contacting the transport trolley.
[0011] The second buffer assembly is connected to the support frame and has a trigger part that is connected to the track and at least part of its structure is located between the first buffer assembly and the track. The trigger part is pressed to form a height difference with the track.
[0012] The rail-mounted unloading platform provided in this application, when the transport trolley containing materials moves to the end of the track, due to the large weight of the transport trolley and the materials inside, when the transport trolley aligns with the trigger part in the second buffer assembly, will force the trigger part to move elastically, thereby causing the wheels of the transport trolley to disengage from the track. Because there is a height difference between the trigger part and the track, the wheels will not retract. The first buffer assembly provides a buffer for the transport trolley in the direction of its movement, offsetting the impact force generated by the sudden stop of the transport trolley and preventing the transport trolley from violently colliding with the support frame. Through the synergistic effect of the first and second buffer assemblies, the transport trolley can be passively, quickly, and accurately stopped, thereby improving unloading efficiency. When the materials in the transport trolley are unloaded, the weight of the transport trolley is greatly reduced, the trigger part elastically resets, and there is no longer a height difference between the trigger part and the track, allowing the transport trolley to move under control to return to the track.
[0013] In some alternative embodiments, the support frame includes:
[0014] Vertical beams, four of which are arranged in parallel at intervals and located at the four corner points of a rectangle;
[0015] A crossbeam, the two ends of which are connected to the ends of two adjacent vertical beams, wherein a secondary beam is connected between the two opposing crossbeams, and the track is connected to the secondary beam;
[0016] A sealing plate is connected to the crossbeam and the vertical beam, or the sealing plate is connected to the crossbeam, to form a semi-enclosure on the support frame.
[0017] In some alternative embodiments, the track is provided with a steel plate base, and the steel plate base is fitted with anchor bolts to connect to the ground.
[0018] In some optional embodiments, there are multiple steel plate bases, wherein at least one steel plate base is provided at each end of the track along its length.
[0019] In some alternative embodiments, the distance between adjacent steel plate bases is no more than 500 mm.
[0020] In some alternative embodiments, the transport trolley is equipped with a push handle, which is provided with a rubber anti-slip sleeve.
[0021] In some optional embodiments, the second buffer component includes:
[0022] An action block having a support plane that is parallel to the track;
[0023] An elastic element is connected to the actuating block and also to the support frame so that the actuating block can reciprocate elastically on the support frame.
[0024] In some alternative embodiments, the elastic element is configured as a helical spring.
[0025] In some alternative embodiments, the first buffer component is located on the support plane.
[0026] In some alternative embodiments, second buffer components are provided on both sides of the track along its length.
[0027] Compared with the prior art, this application has the following advantages and beneficial effects:
[0028] The rail-mounted unloading platform provided in this application, when the transport trolley containing materials moves to the end of the track, due to the large weight of the transport trolley and the materials inside, when the transport trolley aligns with the trigger part in the second buffer assembly, will force the trigger part to move elastically, thereby causing the wheels of the transport trolley to disengage from the track. Because there is a height difference between the trigger part and the track, the wheels will not retract. The first buffer assembly provides a buffer for the transport trolley in the direction of its movement, offsetting the impact force generated by the sudden stop of the transport trolley and preventing the transport trolley from violently colliding with the support frame. Through the synergistic effect of the first and second buffer assemblies, the transport trolley can be passively, quickly, and accurately stopped, thereby improving unloading efficiency. When the materials in the transport trolley are unloaded, the weight of the transport trolley is greatly reduced, the trigger part elastically resets, and there is no longer a height difference between the trigger part and the track, allowing the transport trolley to move under control to return to the track.

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.
[0035] like Figures 1-2 As shown, this application embodiment provides a rail-mounted unloading platform, which includes a support frame 1, a rail 5, a transport trolley 2, a first buffer assembly 3, and a second buffer assembly 4. The rail 5 is connected to the support frame 1. The transport trolley 2 cooperates with the rail 5, so that the transport trolley 2 can slide on the rail 5. The transport trolley 2 forms a cooperation with the rail 5 through rollers provided on it. The first buffer assembly 3 is connected to the support frame 1 and is located on one side of the length direction of the rail 5. There is a gap between the first buffer assembly 3 and the end of the rail 5. The first buffer assembly 3 has a buffer part for contacting the transport trolley 2. The second buffer assembly 4 is connected to the support frame 1. The second buffer assembly 4 has a trigger part. The trigger part is connected to the rail 5, that is, after the wheels on the transport trolley 2 leave the rail 5, they can enter the trigger part. At least part of the structure on the trigger part is located between the first buffer assembly 3 and the rail 5. The trigger part is pressed to form a height difference with the rail 5.
[0036] Operating principle: When the transport trolley 2 moves to the end of the track 5 and approaches the unloading position, the wheels of the transport trolley 2 leave the track 5 and enter the section corresponding to the trigger part. This means that the trigger part provides support for the transport trolley 2 at this time. Since the transport trolley 2 is loaded with material, its overall weight is relatively large, and the trigger part will be compressed and move elastically. At this time, a height difference is formed between the trigger part and the track 5, which means that the wheels on the trigger part sink. The end of the track 5 will mechanically interfere with the wheels, and the transport trolley 2 will not be able to move back. Due to inertia, the transport trolley 2 will continue to move forward and contact the buffer part. The buffer part will provide a buffering effect to offset the impact force of the transport trolley 2, thereby preventing the transport trolley 2 from having a rigid collision, ensuring the stability of the internal material, and realizing the passive and rapid stopping of the transport trolley 2. After the material in the transport trolley 2 is unloaded, the overall weight of the transport trolley 2 is relatively light. At this time, the pressure on the trigger part is small, and the trigger part will perform an elastic reset action, which means that a height difference is no longer formed between the trigger part and the track 5, and the wheels of the transport trolley 2 can then enter the track 5 from the trigger part.
[0037] The track-mounted unloading platform provided in this application embodiment, when the transport trolley 2 containing materials moves to the end of the track 5, due to the large weight of the transport trolley 2 and the materials inside it, when the position of the trigger part in the second buffer assembly 4 corresponds, will force the trigger part to move elastically, thereby causing the wheels of the transport trolley 2 to disengage from the track 5. Since there is a height difference between the trigger part and the track 5, the wheels will not retract. Through the setting of the first buffer assembly 3, a buffer can be provided for the transport trolley 2 in the direction of movement, offsetting the impact force generated by the sudden stop of the transport trolley 2, and avoiding a violent collision between the transport trolley 2 and the support frame 1. Through the synergistic effect of the first buffer assembly 3 and the second buffer assembly 4, the transport trolley 2 can be stopped passively, quickly, and accurately, thereby improving the unloading efficiency. When the materials in the transport trolley 2 are unloaded, the weight of the transport trolley 2 is greatly reduced, the trigger part elastically resets, there is no longer a height difference between the trigger part and the track 5, and the transport trolley 2 can be controlled to return to the track 5.
[0038] In some optional embodiments, the support frame 1 includes vertical beams 11, horizontal beams 12, and a sealing plate 14; four vertical beams 11 are arranged in parallel at intervals and located at the four corner points of a rectangle; the two ends of the horizontal beams 12 are connected to the ends of two adjacent vertical beams 11, wherein the longer horizontal beam 12 is simply referred to as the long horizontal beam 12, and the shorter horizontal beam 12 is simply referred to as the short horizontal beam 12. In the conventional orientation, the top and bottom of the horizontal beams 12 are connected to the horizontal beams 12, wherein secondary beams 13 are also connected between two opposite horizontal beams 12. Usually, multiple secondary beams 13 are connected between two long horizontal beams 12, and the multiple secondary beams 13 are arranged in parallel at intervals along the length direction of the long horizontal beams 12. The secondary beams 13 and the long horizontal beams 12. Vertical connection. In actual implementation, secondary beams 13 are connected to the top and bottom of the vertical beam 11, and the track 5 is connected to the secondary beams 13. The sealing plate 14 is connected to the horizontal beam 12 and the vertical beam 11, which means that in the usual use position, the side of the support frame 1 is connected to the sealing plate 14. The three sides of the support frame 1 are connected to the sealing plate 14 respectively, and the remaining side is not connected to the sealing plate 14 to serve as the entry channel of the transport trolley 2. Alternatively, the sealing plate 14 is connected to the horizontal beam 12, which means that the sealing plate 14 is also connected to the top of the vertical beam 11 to form a semi-enclosure of the support frame 1. That is, one side of the support frame 1 is not connected to the sealing plate 14 to serve as the entry channel of the transport trolley 2.
[0039] In some alternative embodiments, a steel plate base 6 is provided on the track 5, and anchor bolts are fitted on the steel plate base 6 to connect to the ground.
[0040] In this embodiment, the connection between the steel plate base 6 of the track 5 and the ground can further ensure the stability of the track 5 and ensure that the transport trolley 2 can move normally and smoothly on the track 5.
[0041] In some optional embodiments, there are multiple steel plate bases 6, wherein at least one steel plate base 6 is respectively arranged at both ends of the track 5 along its length.
[0042] In this embodiment, multiple steel plate bases 6 can further improve the relative stability of the track 5 and the ground, and can evenly distribute the load from the track 5 and the transport trolley 2, avoiding local stress concentration; at the same time, the dense steel plate bases 6 can also enhance the bending resistance of the track 5, and prevent the track 5 from buckling due to local overload. In actual implementation, the distance between adjacent steel plate bases 6 is no more than 500mm.
[0043] In some alternative embodiments, the transport trolley 2 is equipped with a push handle with a rubber anti-slip sleeve, which facilitates manual pushing / pulling of the transport trolley 2.
[0044] In some optional embodiments, the second buffer assembly 4 includes an action block 41 and an elastic element 42; the action block 41 has a support plane that is parallel to the track 5, meaning that when the action block 41 is in the initial position, the wheel can slide from the track 5 onto the support plane, and the action block 41 as a whole can be regarded as a trigger part; the elastic element 42 is connected to the action block 41, and the elastic element 42 is also connected to the support frame 1 so that the action block 41 can elastically reciprocate on the support frame 1.
[0045] In some alternative embodiments, the elastic element 42 is configured as a helical spring, which can provide a directionally stable elastic force to the actuating block 41, ensuring that the actuating block 41 can accurately return to its original position. At the same time, since the elastic element 42 is only a helical spring, when the transport trolley 2 just contacts the actuating block 41, the actuating block 41 will bear an off-center load. While the actuating block 41 is compressed and descends, it will also generate a small-amplitude flip to form a ramp. This will increase the resistance of the wheels of the transport trolley 2 to move forward, which is conducive to the rapid stopping of the transport trolley 2.
[0046] In some optional embodiments, the first buffer assembly 3 is located on the support plane. The first buffer assembly 3 may include a rigid support plate 31 and a flexible buffer plate 32. The rigid support plate 31 may be made of steel plate, and the flexible buffer plate 32 may be made of polyurethane elastic buffer pad. That is, in the length direction of the track 5, one end of the actuating block 41 is connected to the track 5, and the other end is located below the first buffer assembly 3 and is in contact with the first buffer assembly 3. In this way, the first buffer assembly 3 can play a certain rotation limit role for the actuating block 41, which can prevent the support plane from deflecting to a vertical state.
[0047] In some optional embodiments, a second buffer component 4 is provided on both sides of the track 5 along its length. The end furthest from the first buffer component 3 is the loading position. After the transport trolley 2 is loaded, its weight increases. At this time, the second buffer component 4 can position the transport trolley 2 to prevent it from accidentally sliding on the track 5. After loading is completed, the operator can use a lever to lift the transport trolley 2 so that it returns to the track 5.
[0048] In some optional embodiments, a movable support leg is also movably connected to the support frame 1. The movable support leg is equipped with a rubber pad. During loading and unloading, the movable support leg can be lowered so that the rubber pad contacts the ground, thereby increasing the overall friction between the platform and the ground and preventing the platform from sliding or shifting.
