Description

Technical Field

[0001] This utility model relates to the technical field of weighing platforms for elevators, and specifically to a weighing platform for elevators with an anti-fall-off structure. Background Technology

[0002] Weighing equipment generally refers to instruments used in industry or trade to weigh large objects. It integrates modern electronic technologies such as programmable control, group control, electronic transmission and printing, and screen display, making it more functional and efficient. Weighing equipment mainly consists of three parts: a load-bearing system (such as a weighing pan or scale body), a force transmission system (such as a lever transmission system), and an indication system (such as a dial or electronic display instrument). Lifting equipment with weighing functions can simultaneously weigh items during lifting and transportation. A search revealed existing technology (publication number: CN222024031U), which describes "a lifting weighing platform, including a weighing device and a lifting mechanism. An adjusting plate is installed under the weighing device, and a lifting plate is provided under the adjusting plate. A connecting ball A is fixed at the center of the upper part of the lifting plate, and a connecting tube A is sleeved on the outside of the connecting ball A. The connecting tube A is fixedly connected to the adjusting plate. An adjusting unit is provided between the adjusting plate and the lifting plate. Connecting blocks are fixed at the four corners of the lower part of the lifting plate, and the connecting blocks are fixedly connected to the lifting end above the lifting mechanism. The lifting mechanism and the weighing device are connected to a power supply and a controller via wires. By setting up the adjusting plate, lifting plate, connecting ball A, connecting tube A, and adjusting unit, the equipment can automatically adjust its level, improving the adjustment speed and making the measurement data more accurate."

[0003] While the lifting and weighing platform described in the aforementioned patent documents improves the speed of equipment adjustment and the accuracy of measurement data, the flat surface of the weighing device makes it easy for the weighed items to fall during lifting operations. Furthermore, the device is not suitable for lifting, transporting, and weighing items containing water, such as aquatic products, as water is prone to accumulate and spill during lifting, thus affecting the use of the equipment and impacting weighing accuracy during continuous use. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, a weighing platform for elevators with an anti-fall structure is provided to solve the problems mentioned in the background.

[0005] To achieve the above objectives, a weighing platform for a lifting platform with an anti-fall structure is provided, comprising: a lifting device and a weighing platform. The lifting device is connected to the upper side of the lifting platform, and the weighing platform is located on the upper side of the lifting platform. Collection boxes are connected to both sides of the lifting device, and drain pipes are connected to the outer walls of the collection boxes. A flow guiding cavity is opened inside the lifting platform, and drain ports are opened on both sides of the flow guiding cavity. A flow guide plate is provided on the outer side of the drain ports. A filter screen is opened on the upper side of the lifting platform. An upper mounting plate is connected to the lower end of the weighing platform, and a lower mounting plate is provided on the lower side of the upper mounting plate. A weighing sensor is installed between the upper mounting plate and the lower mounting plate. The lower end of the lower mounting plate is fixed to the upper end of the lifting platform. The weighing platform includes a placement plate, and a telescopic plate is installed at the upper edge of the placement plate. An electro-hydraulic actuator is connected to the outer side of the telescopic plate.

[0006] Furthermore, the inside of the flow guide cavity is provided with a support block, and the bottom of the support block is provided with an arc-shaped bottom.

[0007] Furthermore, the guide plate is configured as an inclined U-shaped trough plate structure, and the guide plate is located above the opening of the collection box.

[0008] Furthermore, a placement groove is provided on the upper side of the placement plate, and a leakage hole is provided at the bottom of the placement groove, with the leakage hole located above the filter screen holes.

[0009] Furthermore, the telescopic plate is disposed around the placement plate, and the telescopic plate includes a solid plate at the bottom, and a hollow plate is fitted on the upper side of the solid plate.

[0010] Furthermore, the electro-hydraulic actuator is fixed to the outer wall of the weighing platform, and the upper end of the electro-hydraulic actuator is connected to the hollow plate included in the telescopic plate through a connecting block.

[0011] Furthermore, the weighing sensor is installed between the upper mounting plate and the lower mounting plate, and the upper mounting plate and the lower mounting plate are of the same size.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When in use, the telescopic plate can be moved upward to an appropriate height by an electro-hydraulic actuator according to the size of the item to be placed. This can block the item when the lifting equipment is raised and lowered, thus preventing the item from falling. It can also accommodate items of different sizes. When the item is taken out, the height of the telescopic plate can be lowered to facilitate the removal of the item. The item is weighed by the weighing sensor between the upper and lower mounting plates.

[0014] 2. When weighing items containing water, place the items in the placement slot of the placement plate. At this time, the water drips down through the holes into the filter screen holes, then enters the guide chamber, and is discharged outward through the drain port and guide plate. Then it flows down into the collection box. When the collection box is full, it can be discharged through the drain pipe. This allows the accumulated water to be guided and discharged during the lifting process, avoiding affecting the function of the equipment and reducing the impact of water on the weighing.

[0021] Reference Figures 1 to 5As shown, this utility model provides a weighing platform for a lift with an anti-fall structure, including: a lift device 1 and a weighing platform 2. The upper side of the lift device 1 is connected to the lifting platform 12, and the weighing platform 2 is located on the upper side of the lifting platform 12. Collection boxes 11 are connected to both sides of the lift device 1, and drain pipes 111 are connected to the outer walls of the collection boxes 11. A guide cavity 121 is opened inside the lifting platform 12, and drain ports 124 are opened on both sides of the guide cavity 121. A guide plate 125 is provided, and a filter screen hole 123 is provided on the upper side of the lifting platform 12. The lower end of the weighing platform 2 is connected to an upper mounting plate 31, and a lower mounting plate 32 is provided on the lower side of the upper mounting plate 31. A weighing sensor 3 is installed between the upper mounting plate 31 and the lower mounting plate 32. The lower end of the lower mounting plate 32 is fixed to the upper end of the lifting platform 12. The weighing platform 2 includes a placement plate 21, and a telescopic plate 24 is installed at the upper edge of the placement plate 21. An electro-hydraulic push rod 26 is connected to the outer side of the telescopic plate 24.

[0022] In this embodiment, the elevator equipment 1, the weighing platform 2, and the weighing sensor 3 constitute the main structure of the weighing platform for the elevator with an anti-fall structure involved in this application.

[0023] The lifting equipment 1 includes a lifting platform 12, which is a scissor lift as described in the prior art, and the upper end of the scissor arm is hinged to the lifting platform 12.

[0024] Specifically, the interior of the guide cavity 121 is designed to be narrow in the middle and wide on both sides, so that the water inside the guide cavity 121 flows out to the drain port 124.

[0025] Specifically, the drain pipe 111 is located on the outer wall of the collection box 11 near the bottom, and the drain pipe 111 is equipped with a manual valve.

[0026] Specifically, the filter screen 123 has a filter screen inside, which prevents water from splashing when it falls and comes into contact with the filter screen. At the same time, the filter screen 123 can also filter out impurities in the flowing water.

[0027] It should be noted that a control display is provided on the outside of the elevator equipment 1 to display the measurement results of the weighing sensor 3.

[0028] like Figure 2 and Figure 5 In the middle, the inside of the flow guiding cavity 121 is provided with a support block 122, and the bottom of the support block 122 is provided with an arc-shaped bottom. The flow guiding plate 125 is provided with an inclined U-shaped groove plate structure, and the flow guiding plate 125 is located above the box opening of the collection box 11. The upper side of the placement plate 21 is provided with a placement groove 22, and the bottom of the placement groove 22 is provided with a leakage hole 23, and the leakage hole 23 is located above the filter screen hole 123.

[0029] Specifically, the bottom of the placement trough 22 is designed with an inner high and an outer low structure to facilitate outward flow.

[0030] Specifically, the guide plate 125 is directly welded to the outer wall of the lifting platform 12.

[0031] Specifically, the perforation 23 is designed as a rectangular hole structure, and its length and width are smaller than the length and width of the filter hole 123.

[0032] As a preferred implementation, by setting the support block 122, the pressure resistance of the top of the lifting platform 12 is enhanced, and the reduced weighing performance is avoided due to the opening of the guide cavity 121.

[0033] like Figure 1 , Figure 3 and Figure 5 In the middle, the telescopic plate 24 is arranged around the placement plate 21, and the telescopic plate 24 includes a solid plate at the bottom, and a hollow plate is fitted on the upper side of the solid plate. The electro-hydraulic push rod 26 is fixed to the outer wall of the weighing platform 2, and the upper end of the electro-hydraulic push rod 26 is connected to the hollow plate included in the telescopic plate 24 through the connecting block 25. The weighing sensor 3 is installed in the middle of the upper mounting plate 31 and the lower mounting plate 32, and the upper mounting plate 31 and the lower mounting plate 32 are set to the same size.

[0034] Specifically, the four electro-hydraulic actuators 26 are connected to a synchronization controller. The controller is programmed to send the same control signal to each electro-hydraulic actuator, enabling them to start and stop simultaneously and run at the same speed.

[0035] Specifically, the top of the hollow slab is designed as a sealed end to prevent impurities from entering and causing contamination.

[0036] As a preferred implementation, by setting the upper mounting plate 31 and the lower mounting plate 32, the contact area between the upper and lower ends of the weighing sensor 3 is increased, thereby increasing the stability of the connection between the weighing platform 2 and the lifting platform 12.

[0037] In use, the telescopic plate can be moved upwards to an appropriate height by an electro-hydraulic actuator, depending on the size of the item being placed. This blocks the item during the lifting process, preventing it from falling. It can accommodate items of different sizes and volumes. When removing the item, the telescopic plate can be lowered for easier retrieval. Weighing is achieved through the upper and lower mounting plates and the weighing sensor between them. When weighing items containing water, the item is placed in the placement slot of the plate. The water drips down through the drain holes into the filter screen, then into the guide chamber, and finally outwards through the drain port and guide plate, flowing downwards into the collection tank. When the collection tank is full, the water is drained through the drain pipe. This process effectively drains accumulated water during lifting, preventing interference with the equipment's functionality and minimizing the impact of water on weighing.

[0038] The weighing platform for elevators with an anti-fall structure of this utility model can effectively solve the problems mentioned in the background technology. It achieves the effect of preventing items from falling during the lifting, transportation and weighing process on the basis of the existing weighing platform technology for elevators with an anti-fall structure. At the same time, it is convenient for weighing aquatic products or damp items, and increases the versatility of the equipment.
