Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision devices inside elevator cars, and in particular to an anti-collision device inside a freight elevator car. Background Technology

[0002] A freight elevator, also known as a cargo elevator or industrial elevator, is a type of elevator equipment specifically designed for the vertical transport of goods. It is widely used in factories, warehouses, supermarkets, logistics centers, construction sites, and other places. Compared with passenger elevators, it places greater emphasis on load-bearing capacity, operating efficiency, and safety. It is usually not used to carry people; only operators are allowed to accompany the goods during transport. Since freight elevators are specifically designed for transporting goods, and goods are often pushed or pulled into the elevator, it is necessary to install anti-collision devices inside the elevator to reduce the damage caused by collisions.

[0003] However, traditional anti-collision methods only install buffer plates inside the car to prevent trolleys and goods from directly impacting the car's inner wall. In this case, the buffer plates are in direct contact with the car's inner wall, and there is a lack of buffer space between the buffer plates and the car's inner wall, which cannot fully transfer the impact force. As a result, the car's inner wall will still be subjected to a large impact force, affecting the anti-collision effect. To address this, we propose an anti-collision device inside the freight elevator car to solve the problems encountered by existing technologies. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] An anti-collision device for a freight elevator car includes an elevator car composed of a front panel, side panels, and a back panel. A buffer assembly is installed on the side surface of the back panel facing the front panel. A liquid storage tank is installed on the side wall of the back panel. The buffer assembly includes a bottom buffer plate installed on one side surface of the back panel. A front buffer plate is installed in front of the bottom buffer plate. A plurality of buffer bags are installed between the front buffer plate and the bottom buffer plate. Each group of buffer bags is connected to a connecting pipe through a branch pipe.

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1:

[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an anti-collision device inside a freight elevator car, including an elevator car composed of a front panel 1, a side panel 2, and a back panel 3. A buffer assembly 4 is installed on the side surface of the back panel 3 facing the front panel 1. A liquid storage tank 5 is installed on the side wall of the back panel 3. The top of the liquid storage tank 5 has an air hole for discharging sucked-in air. The buffer assembly 4 includes a bottom buffer plate 41 installed on one side surface of the back panel 3. A front buffer plate 42 is installed in front of the bottom buffer plate 41. Several buffer bags 43 are installed between the front buffer plate 42 and the bottom buffer plate 41. Each group of buffer bags 43 is connected to a connecting pipe 6 through a branch pipe 46. The upper end of the connecting pipe 6 is connected to the inside of the liquid storage tank 5. A flow control assembly 7 is provided inside the connecting pipe 6.

[0029] By installing several buffer bags 43 between the front buffer plate 42 and the bottom buffer plate 41, and by filling the buffer bags 43, the branch pipes 46, and the connecting pipes 6 with oil, when the goods hit the front buffer plate 42, the impact force will push the front buffer plate 42 and compress the buffer bags 43, causing the internal space of the buffer bags 43 to shrink. This allows the oil inside the bags to flow upward through the branch pipes 46 and the connecting pipes 6 to the storage tank 5. The oil flow absorbs and transfers the force generated by the impact of the goods, thereby reducing the impact force on the inner wall of the car and improving the anti-collision effect of the elevator car.

[0030] The flow area of ​​the connecting pipe 6 can be controlled by the flow control component 7, thereby adjusting the speed of the oil in the buffer bag 43 through the branch pipe 46 and the connecting pipe 6, and adjusting the buffer bag 43's energy absorption effect.

[0031] After the goods are removed, by setting the height of the liquid storage tank 5 higher than that of several buffer bags 43, the oil will gradually flow back into the buffer bags 43 under the influence of gravity, so that the buffer bags 43 return to the state of waiting to absorb energy.

[0032] Example 2:

[0033] Reference Figure 4 as well as Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the flow control component 7 includes a horizontal tube 71 integrally formed on the connecting pipe 6. Both ends of the horizontal tube 71 are closed. A guide groove 72 is provided inside the horizontal tube 71. The guide groove 72 communicates with the inner wall of the connecting pipe 6 and is arranged crosswise. A seal 73 is slidably installed inside the guide groove 72. A threaded hole is opened inside the seal 73. A screw 74 is threadedly connected to the threaded hole of the seal 73. The screw 74 is rotatably installed on the inner wall of the horizontal tube 71. One end of the screw 74 rotatably extends to the outer wall of the horizontal tube 71 and is fixedly installed with a handle 75.

[0035] In use, rotating the handle 75 drives the screw 74 to rotate inside the horizontal tube 71. At the same time, the screw 74 engages with the threaded hole of the seal 73, thereby driving the seal 73 to move inside the guide groove 72, adjusting the position of the seal 73, so that the seal 73 adjusts the area of ​​the flow path of the connecting pipe 6, and thus adjusts the flow rate of the oil.

[0036] Specifically, the cross-sections of both the guide groove 72 and the seal 73 are elliptical.

[0037] By setting the cross-sections of the guide groove 72 and the seal 73 to be elliptical, the seal 73 can move along the path of the guide groove 72, preventing the seal 73 from rotating during movement.

[0038] Example 3:

[0039] Reference Figure 2 as well as Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, the cushioning bag 43 is made entirely of a rubber sheet, and one side surface of the cushioning bag 43 is fixedly connected to the bottom cushioning sheet 41.

[0041] Because the entire cushioning bag 43 is made of rubber sheet, it has a certain degree of elasticity and resilience, and can quickly recover after cushioning.

[0042] Specifically, a rigid support plate 431 is installed between the other side surface of the cushioning bag 43 and the front cushioning sheet 42, and the front cushioning sheet 42 is made of rubber.

[0043] By installing a rigid support plate 431 between the buffer bag 43 and the front buffer plate 42, the rigid support plate 431 can effectively isolate the puncture force of sharp objects and evenly distribute the force to the surface of the buffer bag 43, preventing the buffer bag 43 from being punctured and damaged. By setting the front buffer plate 42 made of rubber, the outer surface of the facility is made soft, which can prevent people from being injured when they touch the protruding parts.

[0044] Specifically, the front buffer plate 42 is fixedly connected to both the upper and lower ends with fixing plates 44, and each fixing plate 44 is fixed to the side wall of the bottom buffer plate 41 by fixing bolts 45.

[0045] The fixed plate 44 restricts the shape of both ends of the front buffer plate 42, so that the front buffer plate 42 is flat and fits the surface of the buffer bag 43. The front buffer plate 42 is easy to remove, replace and maintain by using the fixing bolts 45.

[0046] Specifically, the space between several cushioning bags 43 is filled with sound-absorbing cotton.

[0047] Sound insulation cotton can absorb the sound generated by impact while acting as a buffer, thus reducing noise.

[0048] In use, several buffer bags 43 are installed between the front buffer plate 42 and the bottom buffer plate 41. The buffer bags 43, as well as the branch pipes 46 and the connecting pipes 6, are filled with oil. When the goods hit the front buffer plate 42, the impact force will push the front buffer plate 42 and compress the buffer bags 43, causing the internal space of the buffer bags 43 to shrink. This allows the oil inside the bags to flow upward through the branch pipes 46 and the connecting pipes 6 to the storage tank 5. The oil flow absorbs and transfers the force generated by the impact of the goods, thereby reducing the impact force on the inner wall of the car and improving the anti-collision effect of the elevator car.

[0049] The flow area of ​​the connecting pipe 6 can be controlled by the flow control component 7, thereby adjusting the speed of the oil in the buffer bag 43 through the branch pipe 46 and the connecting pipe 6, and adjusting the buffer bag 43's energy absorption effect.

[0050] After the goods are removed, by setting the height of the liquid storage tank 5 higher than that of several buffer bags 43, the oil will gradually flow back into the buffer bags 43 under the influence of gravity, so that the buffer bags 43 return to the state of waiting to absorb energy.

[0051] Rotating the handle 75 drives the screw 74 to rotate inside the horizontal tube 71. At the same time, the screw 74 engages with the threaded hole of the seal 73, thereby driving the seal 73 to move inside the guide groove 72, adjusting the position of the seal 73, so that the seal 73 adjusts the area of ​​the flow path of the connecting pipe 6, and thus adjusts the flow rate of the oil.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
