Abstract
Description
Technical Field
[0001] The present application relates to the technical field of handling equipment, and in particular to a device and a stereoscopic warehouse used for lifting heavy products of prefabricated buildings up and down stairs. Background Art
[0002] Heavy products in prefabricated buildings usually include various components and equipment that have a large mass and weight during the manufacturing and assembly stages, such as prefabricated concrete wall panels or composite panels. In prefabricated buildings, these heavy products are usually prefabricated in factories and then assembled on site, thereby speeding up the construction progress.
[0003] After the heavy products are prefabricated in the factory, they generally need to be temporarily stored. Usually, the heavy products are transferred to a three-dimensional warehouse for storage. During the transfer process, there are situations where heavy products are transferred from one floor to another. At present, heavy products are mainly transferred by elevators.
[0004] Regarding the above-mentioned related technologies, the current elevator mainly uses chains to connect the four corners of the cargo platform, and uses the chains to drive the cargo platform to rise and fall. Since heavy products are heavy, when the heavy products enter the cargo platform, if the center of the heavy product does not correspond to the center of the cargo platform, the force on the chain on one side will increase. In the long run, the chain will be worn out, causing unstable lifting of the cargo platform, affecting the transportation of heavy products. Utility Model Content

[0018] The adjusting and locking assembly is used to adjust the distance between the limit plate and the side wall of the opening of the hoist installation body and to lock the position of the limit plate.
[0019] By adopting the above technical solution, since the center of the cargo platform corresponds to the center of the elevator installation body, at this time, it is only necessary to make the distance between the two limit plates and the side wall of the opening of the elevator installation body equal, and at this time, the center of the heavy product guided by the limit plate can correspond to the center of the cargo platform. This application uses such a design method to facilitate the staff to adjust the position of the limit plate while ensuring the correspondence between the center of the heavy product and the center of the cargo platform.

[0026] Optionally, a side of the limiting plate facing the feed is provided with a flaring structure, and a flaring size of the flaring structure gradually decreases along the feed direction.
[0027] The adoption of the above technical solution is helpful to guide heavy products between the two limit plates.

[0048] The following is combined with Figure 1-5 This application is described in further detail.
[0049] Example 1
[0050] The present application embodiment discloses a device for lifting heavy products of prefabricated buildings up and down stairs. Figure 1 , including an elevator installation body 10, an in-and-out warehouse conveyor line 20, and a cargo loading mechanism (not shown in the figure). The elevator installation body 10 is surrounded by a wall structure with three closed sides and one open side. The elevator installation body 10 is arranged between the first floor slab and the second floor slab. The in-and-out warehouse conveyor line 20 is installed on the first floor slab or the second floor slab. The in-and-out warehouse conveyor line 20 is connected to the side of the elevator installation body 10 with an opening. In this embodiment, the in-and-out warehouse conveyor line 20 is a roller conveyor line. In other embodiments, the in-and-out warehouse conveyor line 20 can also be a plate conveyor line or a belt conveyor line.
[0051] The cargo loading mechanism includes a cargo loading platform and a chain lifting mechanism. The cargo loading platform is vertically slidably connected to the elevator installation body 10. In this embodiment, the cargo loading platform is a roller conveyor line. The cargo loading platform itself has a driving mechanism, which can realize the movement of products in or out through rollers. The in-and-out conveyor line 20 can be docked with the cargo loading platform to transfer products on the in-and-out conveyor line 20 to the cargo loading platform or transfer products on the cargo loading platform to the in-and-out conveyor line 20.
[0052] The chain lifting mechanism is connected to the four corners of the cargo platform and is used to drive the cargo platform to rise and fall. The chain lifting mechanism is an existing technology and will not be described in detail here.
[0053] The center line of the in-and-out conveyor line 20 along the conveying direction coincides with the center line of the elevator installation body 10 along the horizontal plane, and the center of the cargo platform is connected to the center of the elevator installation body 10 on the same vertical line. Through such an arrangement, when the center of a heavy product is at the center of the in-and-out conveyor line 20 and is transported to the cargo platform, the center of the heavy product corresponds to the center of the cargo platform. At this time, the load on the cargo platform is balanced, reducing the situation where one side of the cargo platform is overloaded, and improving the stability of the cargo platform during the lifting of heavy products.
[0054] Reference Figure 1 and Figure 2The in-and-out conveyor line 20 is provided with limiting devices 30 on both sides along the conveying direction. The limiting devices 30 are used to guide heavy products to the center of the cargo platform. The distance between the limiting devices 30 and the side wall of the opening of the elevator installation body 10 is adjustable.
[0055] Among them, the limiting device 30 includes a guide rod 31, a fixed frame 32, a limiting plate 33 and an adjustment locking assembly 34. The guide rod 31 is fixed to the side wall of the opening of the elevator mounting body 10. The extension direction of the guide rod 31 is perpendicular to the conveying direction of the in-and-out warehouse conveyor line 20. The fixed frame 32 is slidably connected to the guide rod 31, and is bent from the bottom of the in-and-out warehouse conveyor line 20 to the top of the in-and-out warehouse conveyor line 20. The limiting plate 33 is fixed to one end of the fixed frame 32 away from the guide rod 31 and is located above the in-and-out warehouse conveyor line 20. The limiting plate 33 is set in two pieces and the two limiting plates 33 are arranged opposite to each other.
[0056] In this embodiment, the adjustment locking assembly 34 includes a locking screw 341 and a locking nut 342. The locking screw 341 is fixed to the side wall of the opening of the elevator mounting body 10 and passes through the fixing frame 32. The locking nut 342 is threadedly connected to the locking screw 341. The locking nuts 342 are set in two and the two locking nuts 342 clamp the two side surfaces of a fixing frame 32.
[0057] Meanwhile, the outer surface of the guide rod 31 is provided with scales.
[0058] When the position of the limit plate 33 needs to be adjusted, the position of the limit plate 33 is slid, and the distance between the fixing frame 32 and the elevator installation body 10 is checked by the scale. When the distances between the two fixing frames 32 and the elevator installation body 10 are equal, the position of the fixing frame 32 is locked by the locking nut 342. At this time, the center of the heavy product limited by the two limit plates 33 is located at the center of the in-and-out conveyor line 20, so that after the heavy product enters the cargo platform, the center of the heavy product corresponds to the center of the cargo platform.
[0059] In addition, the side of the limit plate 33 facing the feed is provided with a flared structure 331, and the flared size of the flared structure 331 gradually decreases along the feed direction to smoothly guide the heavy products between the two limit plates 33. At the same time, the side of the limit plate 33 facing the center of the in-and-out conveyor line 20 is provided with a wear-resistant coating, which improves the wear resistance of the limit plate 33 and prolongs its service life.
[0060] The implementation principle of an embodiment of the present application, which is a device used for lifting heavy products in prefabricated buildings up and down stairs, is as follows: the present application makes the center of the heavy product coincide with the center of the cargo platform, so that the forces acting on all parts of the cargo platform are the same, thereby reducing the situation where one side of the cargo platform is subjected to excessive force, and improving the stability of the cargo platform during the process of lifting heavy products.
[0061] Example 2
[0062] The difference between this embodiment and embodiment 1 is that the structure of the adjustment locking assembly 34 is different. In this embodiment, referring to Figure 3 The adjustment locking assembly 34 includes a limit pin 343, two guide rods 31 are provided, one guide rod 31 is provided with a plurality of limit holes 344 along its axial direction, a sleeve 345 slidably connected to the outer periphery of the guide rod 31 is installed on the fixing frame 32, and the limit pin 343 passes through the sleeve 345 and the limit hole 344.
[0063] The position of the limit hole 344 is designed according to the sizes of several commonly used products. According to different products, the limit pin 343 is installed in the corresponding position of the limit hole 344 to limit the corresponding product. This design makes it difficult to make mistakes in adjusting the position of the limit plate 33, and it is convenient for the staff to quickly adjust the limit plate 33 when switching product delivery.
[0064] Example 3
[0065] The difference between this embodiment and embodiment 1 is that the structure of the adjustment locking assembly 34 is different. In this embodiment, referring to Figure 4 The adjustment locking assembly 34 includes an adjustment sleeve 346 and two adjustment screws 347. An adjustment sleeve 346 is fixedly connected to the two adjustment screws 347. The thread lines of the two adjustment screws 347 have opposite rotation directions. An adjustment screw 347 is threadedly connected to a fixing frame 32. The end of the adjustment screw 347 is rotatably connected to the elevator mounting body 10.
[0066] By rotating the adjusting sleeve 346, the two adjusting screws 347 rotate, and then the two fixing frames 32 are moved closer to or farther away from each other. Therefore, after the positions of the two limit plates 33 are adjusted in advance, the positions of the two limit plates 33 are adjusted by adjusting the sleeve 346, so that the two limit plates 33 can limit the center of the heavy product, thereby improving the adjustment efficiency.
[0067] The present application also discloses a three-dimensional warehouse, including the above-mentioned equipment for lifting heavy products of prefabricated buildings up and down stairs, referring to Figure 5 , and also includes a shelf 40, and the in-and-out conveyor line 20 is arranged next to the shelf 40. When the heavy products need to be put into the warehouse, they are transferred to the in-and-out conveyor line 20 on the first floor through the equipment for lifting up and down the stairs, and the stacker then transfers the heavy products on the in-and-out conveyor line 20 to the shelf 40. Similarly, when it is necessary to leave the warehouse, the process is reversed. The present application realizes the automated entry, exit and cross-floor transportation of heavy products of prefabricated buildings through a three-dimensional warehouse.
[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
