Description

Technical Field

[0001] This application relates to the field of handling trolley technology, and more particularly to a dual-mode convertible multi-functional handling trolley. Background Technology

[0002] Handling trolleys are widely used in logistics, factory warehousing, construction, moving services, and everyday household applications. Their basic structure typically includes a platform or container for carrying goods and one or more wheels for movement. Users apply pushing or pulling forces, utilizing the rolling of the wheels to overcome friction between the goods and the ground, thus achieving labor-saving transportation.

[0003] However, existing handcarts have the following drawbacks: for example, it is difficult for people to lift some heavy objects onto the platform, which limits their use. Utility Model Content

[0004] The purpose of this application is to provide a dual-mode conversion multi-functional handling trolley with a wider range of applications.

[0005] To achieve the above objectives, this application provides a dual-mode conversion multi-functional handling trolley, including two sets of parallel side panel frames, wheels, a platform, a solid steel frame, and a column structure. The wheels are fixedly installed at the bottom of the side panel frames, allowing the side panel frames to move effortlessly. The platform is located between the two sets of parallel side panel frames, and a vertically arranged solid steel frame is fixedly connected to the side panel frames. The platform and the solid steel frame slide together, and the sliding between the platform and the solid steel frame is restricted by the column structure.

[0006] Based on the above structure, the platform can slide up and down along the solid steel frame, and the platform is restrained by the insert structure. The first method involves sliding the platform to a position near the bottom of the solid steel frame, installing the insert structure to restrict the platform's upward movement, thus allowing goods to be moved to the area between the two side panels above the platform. The second method involves sliding the platform to a position near the top of the solid steel frame, installing the insert structure to restrict the platform's downward movement, and using steel cables to suspend goods in the area between the two side panels below the platform. These two methods can be switched according to actual needs. For heavier objects that are difficult for personnel to lift onto the platform, a suspension method can be used for movement, thus giving this dual-mode convertible multi-functional handling trolley a wider range of applications.

[0007] As a preferred embodiment, at least one of the side panel frames is equipped with an anti-collision component at its center. The anti-collision component restricts the object being transported from the side, ensuring the stability of the object during transport and preventing damage from impact.

[0008] As another preferred embodiment, the side panel frame includes a bottom long frame, a top short frame, two sets of double side frames, and two sets of extension frames arranged in parallel. The double side frames are fixedly connected between the end of the top short frame and the top of the bottom long frame. The extension frames are fixedly connected between the outer side of the double side frames and the top of the bottom long frame. The solid steel frame is fixedly connected between the bottom long frame and the top short frame.

[0009] The structure, consisting of a long bottom frame, a short top frame, double side frames, and an extension frame, is wider at the bottom and narrower at the top, with a lower center of gravity, making it more stable. Moreover, the long bottom frame, short top frame, double side frames, and extension frame are all hollow square tube structures, which makes the overall weight lighter while meeting the structural strength requirements.

[0010] Further preferably, the side panel frame also includes a central frame and several inclined frames, with several inclined frames fixedly connected to the side of the central frame, and the end of the inclined frame away from the central frame being fixedly connected to the bottom long frame or the top short frame.

[0011] The central frame and several diagonal brackets are used to fill the central area of ​​the side panel frame and facilitate the installation of the anti-collision components.

[0012] As another preferred embodiment, the anti-collision component includes an elastic block, a long screw, a rear plate, and a clamping nut. The elastic block is slidably engaged with the central frame. The side of the elastic block away from the area between the two sets of side plate frames is fixedly connected to the rear plate. One end of the long screw is fixedly connected to the central frame. The rear plate is slidably engaged with the long screw, and a clamping nut is threaded onto the long screw. The elastic block is made of rubber / cotton-covered material.

[0013] Adjusting the clamping nut allows the elastic block and back plate to move laterally, and the position of the inner side of the elastic block can be adjusted sequentially to suit items of different thicknesses.

[0014] As another preferred embodiment, the insert structure includes an upper row of holes, a lower insertion hole, and a horizontal column that mates with both the upper row of holes and the lower insertion hole on the side of the solid steel frame. The upper row of holes is located near the top of the solid steel frame, and the lower insertion hole is located near the bottom of the solid steel frame.

[0015] Users can insert the horizontal bar into the upper or lower holes according to their actual needs; for example, inserting the horizontal bar into the lower hole is used to restrict the lower platform from sliding upward; inserting the horizontal bar into the upper hole is used to restrict the upper platform from sliding downward.

[0016] In a further preferred embodiment, the traveling wheels are located at the bottom of the solid steel frame, which allows the weight of the object being transported to be directly transferred to the traveling wheels, making the structure more stable.

[0017] Further preferably, the platform includes two sets of main beams arranged in parallel, a sliding sleeve, two sets of longitudinal frames arranged in parallel, a secondary beam, and a hanging wheel.

[0018] Both ends of the main beam frame are fixedly connected to sliding sleeves, which slide in cooperation with the solid steel frame. The longitudinal frame is fixedly connected between the two sets of main beam frames, and the bottom of the longitudinal frame is fixedly connected to a hanging wheel. Several secondary beam frames are fixedly connected between the two sets of longitudinal frames.

[0019] The main platform, consisting of two sets of main beams, sliding sleeves, two sets of parallel longitudinal frames, and secondary beams, is structurally stable, has a relatively low self-weight, and uses wheels to connect the lifting ropes, making it more convenient to use.

[0020] Compared with the prior art, the beneficial effects of this application are as follows:

[0021] (1) This application enables the platform to slide up and down along the solid steel frame and uses the column structure to restrict the platform to the solid steel frame, which can form the following two methods: The first method is: the platform slides to a position close to the bottom of the solid steel frame, and the column structure is installed to restrict the platform from sliding upward. In this way, the goods can be transported to the area between the two side panels above the platform; The second method is: the platform slides to a position close to the top of the solid steel frame, and the column structure is installed to restrict the platform from sliding downward. The goods can be suspended by steel wire rope in the area between the two side panels below the platform. The above two methods can be switched according to actual application needs. For some heavy objects, it is difficult for personnel to lift them onto the platform. They can be moved by suspension. In this way, the dual-mode conversion multi-functional handling trolley has a wider range of applications.

[0022] (2) This application designs anti-collision components that restrict the transported object from the side, ensuring the stability of the transported object during the transport process and avoiding impact damage. Attached Figure Description

[0032] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0034] like Figure 1-6The dual-mode convertible multi-functional handling trolley shown is used for transporting goods. It specifically includes two sets of parallel side panel frames 1, wheels 3, platform 5, solid steel frame 2, and column structure. The bottom of the side panel frame 1 is fixedly equipped with wheels 3, which allows the side panel frame 1 to move effortlessly. The platform 5 is located between the two sets of parallel side panel frames 1. The solid steel frame 2 is fixedly connected to the side panel frame 1. The platform 5 and the solid steel frame 2 slide together, and the sliding of the platform 5 and the solid steel frame 2 is restricted by the column structure.

[0035] Based on the above structure, platform 5 can slide up and down along the solid steel frame 2, and the platform 5 is restrained by the column structure; the first method is as follows: Figure 1 As shown, platform 5 slides to a position close to the bottom of solid steel frame 2, and after the insert structure is installed, it restricts platform 5 from sliding upward. In this way, goods can be transported to the area between the two side panels 1 above platform 5. The second method is to slide platform 5 to a position close to the top of solid steel frame 2, and after the insert structure is installed, it restricts platform 5 from sliding downward. Goods can be suspended in the area between the two side panels 1 below platform 5 using steel wire ropes. The above two methods can be switched according to actual application needs. For some heavy objects, it is difficult for personnel to lift them onto the platform. They can be moved by suspension. In this way, the dual-mode conversion multi-functional handling trolley has a wider range of applications.

[0036] In one embodiment, at least one side panel frame 1 has a center-mounted anti-collision component 4, such as... Figure 1 As shown, two sets of anti-collision components 4 are preferably provided. The anti-collision components 4 restrict the object being transported from the side, ensuring the stability of the object during the transport process and avoiding impact damage.

[0037] In one embodiment, the side panel frame 1 includes a bottom long frame 101, a top short frame 102, two sets of double side frames 103, and two sets of extension frames 104 arranged in parallel. The bottom long frame 101, the top short frame 102, the two sets of double side frames 103, and the two sets of extension frames 104 are fixedly connected by welding.

[0038] A double-sided frame 103 is fixedly connected between the end of the top short frame 102 and the top of the bottom long frame 101. An extension frame 104 is fixedly connected between the outer side of the double-sided frame 103 and the top of the bottom long frame 101. A solid steel frame 2 is fixedly connected between the bottom long frame 101 and the top short frame 102.

[0039] The structure consisting of the bottom long frame 101, the top short frame 102, the double side frames 103, and the extension frame 104 is wider at the bottom and narrower at the top, with a lower center of gravity, making the structure more stable. Moreover, the bottom long frame 101, the top short frame 102, the double side frames 103, and the extension frame 104 are all hollow square tube structures, which makes the overall weight lighter while meeting the structural strength requirements.

[0040] In one embodiment, the side panel frame 1 further includes a central frame 105 and several inclined frames 106. Four sets of inclined frames 106 are arranged and distributed at the four top corners of the central frame 105. Several inclined frames 106 are fixedly connected to the side of the central frame 105. The end of the inclined frame 106 away from the central frame 105 is fixedly connected to the bottom long frame 101 or the top short frame 102. The central frame 105 and several inclined frames 106 are used to fill the central area of ​​the side panel frame 1 and facilitate the installation of the anti-collision component 4.

[0041] In one embodiment, the anti-collision component 4 includes: an elastic block 401, a long screw 402, a rear plate 403, and a clamping nut 404.

[0042] The elastic block 401 is slidably engaged with the central frame 105. The side of the elastic block 401 away from the area between the two sets of side plate frames 1 is fixedly connected to the back plate 403. One end of the long screw 402 is fixedly connected to the central frame 105. The back plate 403 is slidably engaged with the long screw 402, and a clamping nut 404 is threaded on the long screw 402. The elastic block 401 is made of rubber / cotton-covered material.

[0043] By adjusting the clamping nut 404, the elastic block 401 and the back plate 403 can be moved laterally, and the position of the inner side of the elastic block 401 can be adjusted in sequence to suit items of different thicknesses.

[0044] In one embodiment, the insert structure includes an upper row of holes 201 and a lower insertion hole 202 on the side of the solid steel frame 2, and a horizontal column 203 that mates with both the upper row of holes 201 and the lower insertion hole 202. The upper row of holes 201 is close to the top of the solid steel frame 2, and the lower insertion hole 202 is close to the bottom of the solid steel frame 2.

[0045] Users can insert the horizontal bar 203 into the upper row hole 201 or the lower insertion hole 202 according to their actual needs; for example, inserting the horizontal bar 203 into the lower insertion hole 202 is used to restrict the lower limiting platform 5 to slide upward; inserting the horizontal bar 203 into the upper row hole 201 is used to restrict the upper limiting platform 5 to slide downward.

[0046] In one embodiment, the walking wheels 3 are located at the bottom of the solid steel frame 2, so that the weight of the object being transported can be directly transferred to the walking wheels 3, making the structure more stable.

[0047] In one embodiment, the platform 5 includes: two sets of main beam frames 501 arranged in parallel, a sliding sleeve 502, two sets of longitudinal frames 503 arranged in parallel, a secondary beam frame 504, and a hanging wheel 505.

[0048] Both ends of the main beam frame 501 are fixedly connected to sliding sleeves 502, which slide in cooperation with the solid steel frame 2. The longitudinal frame 503 is fixedly connected between the two sets of main beam frames 501. The bottom of the longitudinal frame 503 is fixedly connected to a hanging wheel 505. Several secondary beam frames 504 are fixedly connected between the two sets of longitudinal frames 503.

[0049] The main platform, consisting of two sets of main beam frames 501, sliding sleeves 502, two sets of parallel longitudinal frames 503, and secondary beam frames 504, has a stable structure and a relatively small self-weight. The lifting wheels 505 are used to connect the lifting ropes, making it more convenient to use.

[0050] The first method is: Figure 1 As shown, the platform 5 slides to a position close to the bottom of the solid steel frame 2. After the column structure is installed, the platform 5 is restricted from sliding upward, so that the goods can be transported to the area between the two side panels 1 above the platform 5.

[0051] The second method is to slide the platform 5 to a position close to the top of the solid steel frame 2, install the column structure to restrict the platform 5 from sliding downwards, and use steel wire ropes to suspend the goods in the area between the two side panels 1 below the platform 5.

[0052] The two methods described above can be switched according to actual needs. When faced with heavy objects that are difficult for people to lift onto the platform, they can be moved by suspension. In this way, the dual-mode convertible multi-functional handling trolley has a wider range of applications.

Those skilled in the art should understand that this application is not limited to the above embodiments.
