These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0031] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0032] In the related art, when transporting heavy objects in a staircase building, since it is difficult for a trolley to move on the stairs, it is often necessary for multiple workers to lift the heavy objects together and then transport them to other floors through the stairs, making the transportation process of the heavy objects labor-intensive and inefficient.

[0033] In addition, if the heavy objects are hoisted by hoisting, hoisting equipment must be set up on site, making the process more complicated and labor-intensive.

[0034] In this regard, the present application provides an article transporting equipment, which is provided with a frame main body; a carrying mechanism, the carrying mechanism includes a carrying assembly and a supporting assembly arranged on the frame main body, the carrying assembly is used to hang articles, and the supporting assembly is used to support the bottom of the articles; and a crawling mechanism, the crawling mechanism is movably arranged on the frame main body so that the crawling mechanism can be unfolded or folded relative to the frame main body, and the crawling mechanism is used to walk on stairs. The technical means of transporting articles and the frame main body along the stairs solves the problems of high work intensity and low transportation efficiency when transporting heavy objects on stairs.

[0035] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, the article transporting equipment includes: a frame body 100; a carrying mechanism, which includes a carrying assembly 200 and a supporting assembly 300 arranged on the frame body 100, the carrying assembly 200 is used to hang articles, and the supporting assembly 300 is used to support the bottom of the articles; a crawling mechanism 400, which is movably arranged on the frame body 100 so that the crawling mechanism 400 can be unfolded or folded relative to the frame body 100, and the crawling mechanism 400 is used to walk on stairs to transport articles and the frame body 100 along the stairs.

[0037] It should be noted that the frame body 100 may include a frame, a plurality of running wheels 110 disposed at the bottom of the frame, and a handrail 120 disposed on the frame. When in use, the frame body is moved by holding the handrail 120 and pushing the frame. Of course, the frame body 100 may also have other structures, as long as it can roll or move on the ground, and there is no limitation to this.

[0038] Secondly, the crawling mechanism 400 is located at the front end of the frame body 100 along the walking direction. The crawling mechanism 400 can move relative to the frame body 100 to expand or fold the crawling mechanism 400 according to the usage scenario, thereby improving adaptability to different usage scenarios.

[0039] The loading mechanism is located at the rear end of the vehicle frame 100 in the direction of travel. Working in conjunction with the crawling mechanism 400, it helps balance the weight distribution of the entire transport system. The loading assembly 200 sits above the support assembly 300. To place an item, simply attach it to the loading assembly 200 and then place the support assembly 300 against the bottom of the item, ensuring a secure placement.

[0040] In other embodiments, the crawling mechanism 400 and the object-carrying assembly may be arranged in other directions of the vehicle frame body 100 , which is not limited thereto.

[0041] During use, the object is hooked onto the loading assembly 200, the support assembly 300 is placed against the bottom of the object, and the frame body 100 is then pushed to transport the object. To navigate stairs, the crawling mechanism 400 is simply deployed and placed against the stairs (while holding the handrail 120 on the frame body 100). The crawling mechanism 400 is then operated to move along the stairs, thereby transporting the frame body 100 and the object. This significantly reduces the labor intensity of transporting heavy objects up the stairs, making the process of transporting objects up the stairs more labor-saving and improving the efficiency of heavy object transportation. Furthermore, this transport process does not require the assistance of multiple personnel, reducing labor consumption and resolving the problem of high labor intensity and low transportation efficiency when transporting heavy objects up the stairs.

[0042] It is understood that when not transporting items on stairs, the crawler mechanism 400 can be folded to reduce the overall size of the item transport device and the space it occupies. This can reduce the possibility of the crawler mechanism 400 accidentally hitting surrounding objects when subsequently walking on the road, and can also improve the safety of subsequent docking.

[0043] like Figure 1 As shown, in some embodiments, the object carrying assembly 200 includes a first clamping member 210 disposed on the frame body 100 , and the first clamping member 210 is used to hang objects.

[0044] In this embodiment, the first clamping member 210 can be a hook, providing a location for hanging an item. During use, the upper end of the item simply needs to be hooked onto the first clamping member 210. In other embodiments, the first clamping member 210 can also be a clamping claw or other structure, without limitation.

[0045] like Figure 1 As shown, further, the first clamping member 210 has a hanging groove 211, and at least a portion of the article is hung in the hanging groove 211;

[0046] The object carrying assembly 200 further includes a second clamping member 220 movably disposed on the frame body 100 . The second clamping member 220 is used to restrict at least a portion of the object within the hanging slot 211 .

[0047] It should be noted that the first clamping member 210 has a hanging slot 211 , and the notch of the hanging slot 211 is upwardly facing, so that the part of the object hung on the first clamping member 210 is located in the hanging slot 211 .

[0048] The second clamping member 220 is movably mounted on the vehicle frame body 100 and is located above the first clamping member 210. After an item is hooked to the first clamping member 210, the second clamping member 220 can be moved toward the first clamping member 210 to cover the hooking slot 211. This confines the portion of the item hooked to the first clamping member 210 within the hooking slot 211, thereby reducing the possibility of the item slipping off the first clamping member 210 during subsequent transportation.

[0049] like Figure 1 As shown, in some embodiments, the object carrying assembly 200 further includes a movable seat 230 and a first lifting member 240. The movable seat 230 is vertically slidably disposed on the vehicle frame body 100. The first lifting member 240 is used to control the lifting of the movable seat 230.

[0050] The first clamping member 210 and the second clamping member 220 are both disposed on a movable seat 230 . The movable seat 230 is configured to move the second clamping member 220 when it rises, so that the second clamping member 220 closes the hanging groove 211 .

[0051] The movable seat 230 is vertically slidably mounted on the vehicle frame 100. The first lifting member 240 is secured to the top of the vehicle frame 100 by screwing, welding, or other means. The first lifting member 240 may be a hydraulic cylinder, a pneumatic cylinder, or other structure, and is not limited thereto. The movable end of the first lifting member 240 faces downward and is connected to the movable seat 230, thereby enabling the movable seat 230 to be raised or lowered by the first lifting member 240.

[0052] During implementation, a vertically extending slide groove can be set on the frame body 100, and one end of the movable seat 230 is clamped and slidably set in the slide groove, so that the sliding of the movable seat 230 is guided by the slide groove, thereby improving the stability of the movable seat 230 when sliding.

[0053] At this time, the end of the movable seat 230 away from the slide groove extends toward the rear end of the vehicle frame body 100 in the forward direction. The first clamping member 210 is fixed to the rear end of the movable seat 230, and the second clamping member 220 is movably disposed at the rear end of the movable seat 230. As the movable seat 230 rises, the second clamping member 220 can be synchronously controlled to move and cover the hanging groove 211.

[0054] Once an item is attached to the first clamping member 210, the first lifting member 240 controls the movable seat 230 to rise, thereby lifting the item. Furthermore, while lifting the item, the second clamping member 220 is simultaneously activated and the attachment slot 211 is closed, further enhancing the secure attachment of the item. Next, the support assembly 300 is placed against the bottom of the item to lift it from below, reducing the tension on the first clamping member 210 and minimizing the possibility of the item swaying, further ensuring the secure placement of the item during transport.

[0055] like Figure 1 and Figure 3 As shown, specifically, the second clamping member 220 is rotatably disposed on the movable seat 230;

[0056] The second clamping member 220 is provided with a linkage member 221 and an elastic return member 222. The second clamping member 220 is connected to the frame body 100 via the linkage member 221. When the movable seat 230 rises, the linkage member 221 drives the second clamping member 220 to rotate toward the first clamping member 210.

[0057] The elastic return member 222 is used to drive the second clamping member 220 to rotate away from the first clamping member 210 when the movable seat 230 descends.

[0058] When the movable seat 230 rises, the movable seat 230 moves relative to the frame body 100 , and then drives the second clamping member 220 to rotate toward the first clamping member 210 through the linkage member 221 , thereby restricting the part of the article hung on the first clamping member 210 within the hanging groove 211 .

[0059] like Figure 3 As shown, further, the linkage member 221 includes a connecting rod, the second clamping member 220 has a connecting portion 223, one end of the connecting rod is hinged to the connecting portion 223, and the other end of the connecting rod is hinged to the frame body 100.

[0060] In this embodiment of the present application, the rotating portion of the second clamping member 220 is formed with a connecting portion 223, which is arranged at an angle to the second clamping member 220. One end of a connecting rod is hinged to the connecting portion 223, and the other end of the connecting rod is hinged to the frame body 100. When the movable seat 230 rises, the movable seat 230 moves relative to the frame body 100, causing the connecting portion 223 to be pulled by the connecting rod, which in turn drives the second clamping member 220 to rotate toward the first clamping member 210, thereby confining the portion of the object hanging on the first clamping member 210 within the hanging slot 211.

[0061] Of course, the linkage member 221 can also be a multi-link structure; the linkage member 221 can also be a traction rope, one end of the traction rope is connected to the connecting part 223, and the other end of the traction rope is connected to the frame body 100, so that when the movable seat 230 rises, the second clamping member 220 is pulled by the traction rope to drive the second clamping member 220 to rotate toward the first clamping member 210.

[0062] The elastic return member 222 can be a torsion spring, which is coaxially arranged on the rotating portion of the second clamping member 220, and the two ends of the torsion spring are respectively connected to the second clamping member 220 and the movable seat 230. When the movable seat 230 descends, the linkage member 221 will release the traction on the connecting portion 223. At this time, the torsion spring can push the second clamping member 220 to rotate away from the first clamping member 210, thereby releasing the restriction on the part of the object hanging on the first clamping member 210, and facilitating the subsequent removal of the object from the first clamping member 210.

[0063] In other embodiments, the elastic return member 222 may also be a spring or other structures, as long as it can enable the second clamping member 220 to have a tendency to rotate away from the first clamping member 210, and there is no limitation on this.

[0064] It should be noted that when the linkage member 221 is configured as a single connecting rod, since the connecting rod itself is rigid, when the movable seat 230 descends, the connecting rod will reset, exerting a certain pushing effect on the connecting portion 223, that is, it is able to push the second clamping member 220 to rotate away from the first clamping member 210. In this case, the elastic return member 222 can be installed or not according to actual needs. For example, the elastic return member 222 can be installed; of course, if the elastic return member 222 is installed, the reset effect of the second clamping member 220 will be better.

[0065] like Figure 1 As shown, in some embodiments, the support assembly 300 includes a support member 310 and a second lifting member. The support member 310 is vertically slidably arranged on the frame body 100, and the second lifting member is used to control the lifting of the support member 310 so that the support member 310 abuts against the bottom of the object.

[0066] The support member 310 can be a plate-like structure, a grid structure or other structures, which are not limited. One end of the support member 310 is vertically slidably disposed on the vehicle frame body 100 , and the support member 310 is located below the object-carrying assembly 200 .

[0067] The second lifting member can be a hydraulic cylinder, a pneumatic cylinder, an electric telescopic rod, or other structure, without limitation. The second lifting member is vertically fixed to the vehicle frame body 100. The second lifting member can be fixed to the vehicle frame body 100 by screwing, welding, clamping, or other means. The movable end of the second lifting member is connected to the support member 310. The second lifting member can be located above or below the support member 310.

[0068] During use, after an item is attached to the first clamping member 210, the first lifting member 240 controls the movable seat 230 to rise, thereby lifting the item and tightening it upward. This simultaneously drives the second clamping member 220 to lock the item where it is attached to the first clamping member 210. The second lifting member then drives the support member 310 to abut against the bottom of the item, lifting it. This reduces the load on the first clamping member 210, extending its service life, and improving the stability of the item for easier transportation.

[0069] like Figure 1 As shown, in some embodiments, the crawling mechanism 400 includes a track member 410 movably connected to the frame body 100 , and the track member 410 is used to contact the stairs to transport the frame body 100 and the objects along the stairs.

[0070] It should be noted that the track member 410 is disposed at the front end of the vehicle frame 100 in the forward direction. The track member 410 comprises a closed-loop track body, a plurality of rollers disposed inside the track body, and a motor for controlling the rotation of the rollers. During operation, the motor controls the rotation of the rollers, which in turn drive the track body to rotate, allowing the track body to travel along stairs. Of course, the track member 410 may also utilize existing crawler wheels, such as those used in some construction machinery, without limitation.

[0071] When the entire article transport device is moved to a stairway, the track member 410 can be brought into contact with the stairway and then operated, so that the track member 410 can crawl along the stairway, thereby transporting the frame body 100 and the articles along the stairway with relatively little effort. It should be noted that to further ensure the safety of the transport process, the operator only needs to hold the handrail 120 on the frame body 100.

[0072] Furthermore, a plurality of resistance-increasing portions are provided on a surface of the track member 410 that contacts the stairs.

[0073] Specifically, the outer surface of the crawler body is provided with a plurality of drag-increasing portions. These drag-increasing portions may be raised strips or bumps fixed to the surface of the crawler body by welding, integral molding, or other means. If they are raised strips, they extend perpendicular to the direction of travel of the crawler body. The drag-increasing portions may also be grooves provided on the surface of the crawler body, or may have other structures, without limitation.

[0074] When the track member 410 crawls along the stairs, the friction resistance between the resistance-increasing portion and the stairs is reduced, thereby reducing the possibility of the entire article transporting equipment sliding down the stairs, thereby ensuring the safety and stability of the transport process.

[0075] like Figure 1 As shown, in some embodiments, the crawling mechanism 400 further includes a third lifting member 420, and one end of the track member 410 is rotatably connected to the frame body 100. The third lifting member 420 is used to control the rotation of the track member 410 relative to the frame body 100 to unfold or fold the track member 410.

[0076] One end of the track member 410 is rotatably connected to the front end of the vehicle frame 100 in the forward direction. The third lifting member 420 can be a pneumatic cylinder, a hydraulic cylinder, an electric telescopic rod, or other structure. One end of the third lifting member 420 is hinged to the vehicle frame 100, and the other end is hinged to the track member 410. The third lifting member 420 can thus be used to control the rotation of the track member 410 toward or away from the vehicle frame 100, thereby enabling the track member 410 to be deployed or folded. The inclination angle of the track member 410 can also be adjusted, thereby improving the performance of the track member 410.

[0077] In other embodiments, the track member 410 may also be connected to the vehicle frame body 100 through a sliding connection or other rotational manners, which is not limited thereto.

[0078] In actual implementation, the control switches of the first lifting member 240 , the second lifting member and the third lifting member 420 may all be provided on the armrest 120 . Of course, they may also be provided at other locations, and there is no limitation to this.

[0079] The article transporting equipment provided in the embodiment of the present application reduces the workload when transporting heavy objects on stairs and improves the efficiency of transporting heavy objects by arranging a carrying assembly 200 for suspending articles and a supporting assembly 300 for supporting articles on the frame body 100, and arranging a crawling mechanism 400 on the frame body 100.

[0080] Finally, it should be noted that other embodiments of the present invention will readily occur to those skilled in the art after considering the specification and practicing the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. It is not limited to the precise structure described above and shown in the drawings, and various modifications and variations may be made without departing from the scope of this application. The scope of this application is limited solely by the appended claims.
