Description

Technical Field

[0001] This utility model belongs to the field of body transport technology, specifically relating to a novel track structure for a body transport device. Background Technology

[0002] The funeral industry involves the handling of remains, which takes place in various settings. For those who die in hospitals, the body can be transported via elevator. However, for those who die in residential buildings, especially high-rise buildings, although elevators are available, other residents may be reluctant to use them to transport the body. Therefore, the body must be carried down the stairs.

[0003] CN202210357004.X discloses a body transport device, which has a powered track installed below a body-bearing plate (equivalent to a stretcher) via a first lifting mechanism. The powered track allows it to move on the ground and stairs. As is known, a track is a flexible chain link driven by a drive wheel, surrounding the drive wheel, road wheel, idler wheel, and track support wheel. The track is composed of track plates and track pins, with the track pins connecting the track plates to form a track chain link. The track chain link is a flexible chain link and does not have the function of supporting the body-bearing plate. The first lifting mechanism is installed by a support frame set inside the track chain link, and the first lifting mechanism is connected to the body-bearing plate, thus the body-bearing plate is supported by the support frame inside the track chain link. In this type of device, the track chain link is completely exposed, which does not provide adequate protection. To protect the track chain link, a separate protective shell is needed, making the structure more complex. Therefore, it is necessary to provide an alternative track structure. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art. The purpose of the present invention is to provide a novel track structure for a body transport device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel track structure for a body transport device, comprising a track body with flexible track links capable of running on the ground and stairs, and a load-bearing outer shell with at least a lower opening. The load-bearing outer shell serves as a load-bearing mechanism to support the stretcher of the body transport device. The interior of the load-bearing outer shell is a cavity for installing the track body. The downward section of the track links can extend outward through the lower opening of the load-bearing outer shell and contact the ground.

[0006] The above technical solution allows the load-bearing outer shell to protect the track body and also serve as a stretcher supporting the body transport device, resulting in a simple structure.

[0007] In a preferred embodiment of this utility model, the load-bearing outer shell is made of aluminum alloy.

[0008] The above technical solution utilizes aluminum alloy, which has high strength and is lightweight, thus reducing the overall weight.

[0009] In a preferred embodiment of this utility model, a sliding plate extending along its length is fixedly connected inside the load-bearing outer shell. The sliding plate is located in the track chain link and close to the upper surface of the downward section of the track chain link. When the ground is uneven or when going up or down stairs, the downward section of the track chain link can contact the lower surface of the sliding plate.

[0010] The above technical solution allows the track chain links to deform and contact the sliding plate when the ground is uneven or when going up or down stairs. The sliding plate lubricates and protects the track chain links, extending their service life. Moreover, when the track chain links deform, they only contact the sliding plate and not the load-bearing outer shell, making it more stable.

[0011] In a preferred embodiment of this utility model, the sliding plate is a nylon plate made of nylon.

[0012] The above technical solution uses nylon sheets for the sliding plate, which is low in cost, high in strength, and has good wear resistance.

[0013] In a preferred embodiment of the present invention, the bottom of the sliding plate has a limiting groove with an opening at the lower end, and the top of the downward section of the track chain extends into the limiting groove.

[0014] The above technical solution, by setting a limiting groove, limits and guides the top of the downward section of the track chain link, restricting the track chain link from sliding out when turning, and further improving the protective effect of the sliding plate on the track chain link.

[0015] In another preferred embodiment of the present invention, the novel track structure includes a front flat section in contact with the ground and an upwardly inclined rear section located behind the front flat end.

[0016] The aforementioned technical solution, with its rear-curved section, reduces the footprint of the new tracked structure compared to a completely straight section. When the stretcher is tilted forward via the support frame, the overall volume is smaller, which is beneficial for the operation of the body transport device in confined spaces such as stair platforms.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0026] This utility model provides a novel track structure for a body transport device, such as... Figures 1-3As shown, in a preferred embodiment, the novel track structure includes a track body with flexible track links 12 capable of running on the ground and stairs, and a load-bearing outer shell 11 with at least a lower opening. The structure of the track body adopts existing technology and is not an innovation of this utility model, so it will not be described in detail here. The cross-section of the load-bearing outer shell 11 is a rectangle with an open lower end. The load-bearing outer shell 11 is made of multiple load-bearing plates spliced ​​together (e.g., welded or bolted). The load-bearing outer shell 11 is made of aluminum alloy. The interior of the load-bearing outer shell 11 has a cavity for installing the track body. The downward section of the track links 12 can extend out through the lower opening of the load-bearing outer shell 11 and contact the ground. The load-bearing outer shell 11 does not affect the operation of the track body.

[0027] The load-bearing outer shell 11 of this utility model serves as a load-bearing mechanism to support the stretcher 30 of the body transport device, specifically as follows: Figure 1 As shown, two symmetrical new track structures 10 are arranged on the left and right sides along the width direction of the stretcher 30. The support frame 20 under the stretcher 30 is fixed to the top of the load-bearing shell 11 by bolts. The load-bearing shell 11 supports the stretcher 30 through the support frame 20. At the same time, the load-bearing shell 11 covers the track body and can protect the track body.

[0028] like Figure 2 and Figure 3 As shown, a sliding plate 13 extending along its length is fixedly connected inside the load-bearing outer shell 11. The sliding plate 13 is a nylon plate made of nylon. Support plates 132 are fixedly connected to both sides of the sliding plate 13. The support plates 132 are fixed to the load-bearing outer shell 11 by bolts, thereby fixing the sliding plate 13 in the load-bearing outer shell 11. The sliding plate 13 is located in the track link 12 and close to the upper surface of the downward section of the track link 12. Since the track link 12 is a flexible link, when the ground is uneven or when going up or down stairs, the downward section of the track link 12 deforms under the action of protrusions and contacts the lower surface of the sliding plate 13, which lubricates and protects the track link 12.

[0029] like Figure 3 As shown, the bottom of the sliding plate 13 has a limiting groove 131 with an opening at the lower end. The top of the downward section of the track chain link 12 extends into the limiting groove 131. The two side walls on the left and right sides of the limiting groove 131 limit the top of the downward section of the track chain link 12 on both sides. When turning, it restricts the track chain link 12 from sliding out, further improving the protective effect of the sliding plate 13 on the track chain link 12.

[0030] like Figure 1As shown, in another preferred embodiment, the novel track structure 10 includes a front flat section 101 that contacts the ground and an upwardly inclined rear section 102 located behind the front flat section. Compared to a completely straight section, the rear inclined section 102 reduces the footprint of the novel track structure 10. When the stretcher 30 is tilted forward by the support frame 20, the overall volume is smaller, which is beneficial for the operation of the body transport device in confined spaces such as stair platforms.
