Description

Technical Field

[0001] This application relates to the technical field of lifting frames, and in particular to a quick-disassembly lifting frame. Background Art

[0002] A lifting frame is a construction machinery used to adjust the height of an object. It is mostly made of aluminum alloy or steel, with light weight and high strength. It is widely used in areas such as factory warehouses, port terminals, construction projects, garages, and airports, mainly responsible for tasks such as cargo transportation, heavy object handling, and working at heights.

[0003] At present, most of the lifting frames for transporting goods are relatively large in size and difficult to disassemble and assemble. When it is necessary to quickly change the working location or perform equipment maintenance, the work efficiency is low, which increases the time for job preparation and completion. At the same time, it also increases the difficulty of storage and transportation, restricting the flexibility and adaptability of the lifting frame, and thus affecting the overall work efficiency and economy. Summary of the Utility Model

[0004] In order to improve the quick disassembly and assembly of the lifting frame, this application provides a quick-disassembly lifting frame.

[0005] A quick-disassembly lifting frame provided by this application adopts the following technical solutions:

[0006] A quick-disassembly lifting frame includes a base. One side of the base is hinged with a support frame. A fixing component is arranged on one side of the support frame. The fixing component is used to support and fix the included angle between the support frame and the base. The support frame is slidably connected with a lifting seat. The support frame is connected with a lifting drive component. The lifting drive component is used to drive the lifting seat to lift and lower. The lifting seat is hinged with a lifting platform for carrying goods.

[0007] By adopting the above technical solutions, when disassembly and assembly are required, the fixing component is removed, so that the base is folded onto the support frame, and the lifting platform is folded onto the lifting seat, thereby reducing the volume of the lifting frame, realizing quick disassembly and assembly, and improving the quick disassembly and assembly of the lifting frame.

[0008] Optionally, the fixing component includes a fixing piece and a locking piece. The fixing piece is hinged with the base. One end of the fixing piece away from the base is fixed to the support frame through the locking piece. The fixing piece, the base, and the support frame form a triangle.

[0009] By adopting the above technical solutions, a triangular support is formed for the support frame, enhancing the installation stability of the support frame and reducing the possibility of the lifting platform falling when lifting and lowering goods.

[0010] Optionally, the fixing member includes a fixing rod and a fixing plate. The fixing rod is hinged to the base, and one end of the fixing rod away from the base is hinged to the fixing plate. The support frame is provided with an insertion slot, the fixing plate is inserted into the insertion slot, the fixing plate is in contact with the slot wall of the insertion slot, and the fixing plate is fixed to the support frame by the locking member.

[0011] By adopting the above technical solution, the fixing plate is inserted into the insertion slot to enhance the friction between the fixing member and the support frame, thereby further enhancing the installation stability of the support frame.

[0012] Optionally, the support frame includes a base and a support frame body. The base and the bottom of the support frame body are connected at a right angle, and the base is hinged to the base.

[0013] By adopting the above technical solution, the base is placed on the operating ground, and the support frame body is directly made vertical without the need to adjust the vertical state of the support frame body, improving the installation efficiency of the lifting frame.

[0014] Optionally, a connecting member is hinged to the bottom of the support frame. The connecting member is threadedly connected with an adjusting rod, and the bottom of the adjusting rod is connected with a support seat.

[0015] By adopting the above technical solution, the support frame is further supported. Moreover, when the operating ground is uneven, the installation stability of the support frame can be further improved by adjusting the position of the adjusting rod.

[0016] Optionally, a connecting seat is connected to one end of the support frame away from the lifting platform, and a universal wheel is connected to the connecting seat.

[0017] By adopting the above technical solution, when the lifting frame needs to be moved, the support frame is tilted to make the universal wheel contact the operating ground, thereby improving the moving convenience of the lifting frame. Moreover, the possibility that the universal wheel causes the lifting frame to move during the lifting operation of the lifting frame and results in unstable lifting operation is reduced, thereby improving the lifting safety of the lifting frame.

[0018] Optionally, a handle is connected to one side of the support frame close to the connecting seat.

[0019] By adopting the above technical solution, a force application point is provided for the tilting operation of the support frame, thereby improving the tilting convenience of the support frame.

[0020] Optionally, a support plate is connected to one end of the lifting seat away from the support frame, and the support plate is used to support the lifting platform.

[0021] By adopting the above technical solution, the lifting platform is supported, reducing the possibility of the hinge point between the lifting platform and the lifting seat breaking.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When disassembly and assembly are required, the fixing component is removed, so that the base can be folded onto the support frame, and the lifting platform can be folded onto the lifting seat, thereby reducing the volume of the lifting frame, achieving rapid disassembly and assembly, and improving the disassembly and assembly speed of the lifting frame;

[0024] 2. It forms a triangular support for the support frame, enhances the installation stability of the support frame, and reduces the possibility of the lifting platform dropping when lifting goods;

[0025] 3. When the lifting frame needs to be moved, the support frame is tilted to make the universal wheels contact the operating ground, thereby improving the mobility of the lifting frame. Moreover, it reduces the possibility that the universal wheels cause the lifting frame to move during the lifting operation of the lifting frame, resulting in unstable lifting operation, and further improves the lifting safety of the lifting frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following is a further detailed description of the present application with reference to the attached Figure 1-2 to the present application.

[0031] An embodiment of the present application discloses a quick-disassembly lifting frame.

[0032] Refer to Figure 1 and Figure 2, A quick-release lifting frame, including a base 1. One side of the base 1 is hinged with a support frame 2. One side of the support frame 2 is provided with a fixing component, which is used to support and fix the included angle between the support frame 2 and the base 1. A sliding groove 21 is opened on the inner wall of the support frame 2, and a sliding wheel 22 is arranged in the sliding groove 21. The sliding wheel 22 rolls directionally along the sliding groove 21. The sliding wheel 22 is rotatably connected with a lifting seat 4. The lifting seat 4 is slidably connected to the support frame 2 through the sliding wheel 22. The lifting seat 4 is located on the top of the base 1. One end of the support frame 2 away from the base 1 is fixedly connected with a lifting drive component 41, which is used to drive the lifting seat 4 to lift. The lifting seat 4 is hinged with a lifting platform 42 for carrying goods. In this embodiment, the lifting drive component 41 adopts a winch.

[0033] When installing the lifting frame, press one end of the support frame 2 close to the base 1 against the ground, rotate the base 1, and adjust the included angle between the base 1 and the support frame 2. When the included angle is 90°, fix the angle between the base 1 and the support frame 2 through the fixing component, so that the base 1 lies flat on the operating ground, so that the support frame 2 is placed perpendicular to the operating ground. Subsequently, rotate the lifting platform 42 so that the side of the lifting platform 42 for carrying goods faces upward, which is convenient for placing goods on the lifting platform 42, thereby completing the installation of the lifting frame and improving the installation convenience of the lifting frame; when disassembling the lifting frame, reverse the installation operation of the lifting frame, rotate the lifting platform 42 towards the support frame 2, so that the lifting platform 42 folds onto the lifting seat 4, remove the fixing component, make the included angle between the support frame 2 and the base 1 free, rotate the base 1 towards the support frame 2, so that the base 1 folds onto the support frame 2, thereby reducing the volume of the lifting frame and facilitating the transportation and storage of the lifting frame. The disassembly and assembly structure of the lifting frame is simple, which improves the disassembly and assembly convenience of the lifting frame.

[0034] The support frame 2 includes a base 23 and a support frame 24. The bottom of the base 23 and the support frame 24 are connected at a right angle, and the base 23 and the support frame 24 are integrally formed. One end of the base 23 away from the support frame 24 is hinged with the base 1, which reduces the vertical installation time of the support frame 24 and thus improves the disassembly and assembly efficiency. The sliding groove 21 is opened on the inner wall of the support frame 24, and the side wall of the lifting seat 4 is attached to the inner wall of the support frame 24.

[0035] The fixing component includes a fixing piece and a locking piece 3. One end of the fixing piece is hinged with one end of the base 1 away from the base 23, and the end of the fixing piece away from the base 1 is fixed to the support frame 24 through the locking piece 3. The fixing piece, the base 1 and the support frame 24 are triangular, which improves the installation stability of the support frame 24.

[0036] The fixing member includes a fixing rod 31 and a fixing plate 32. One end of the fixing rod 31 is hinged to the end of the base 1 away from the pedestal 23, and the end of the fixing rod 31 away from the base 1 is hinged to the fixing plate 32. A through slot 241 is formed on the side of the support frame 24 close to the base 1. The fixing plate 32 is inserted into the through slot 241, and the fixing plate 32 is in contact with the slot wall of the through slot 241. The fixing plate 32 is slidably connected to the support frame 24 through the through slot 241. The fixing plate 32 is fixed to the support frame 24 by a locking member 3. The locking member 3 is threadedly connected to the support frame 24, and the locking member 3 abuts against the fixing plate 32. In the embodiment, the locking member 3 is a locking bolt.

[0037] When fixing the support frame 24, rotate the base 1, insert the fixing plate 32 into the through slot 241, adjust the position of the base 1 so that the bottom surface of the base 1 and the bottom surface of the pedestal 23 are on the same horizontal plane. At this time, the end of the fixing plate 32 away from the fixing rod 31 abuts against the circumferential wall of the through slot 241. Insert the locking member 3 through the fixing plate 32 and twist the locking member 3. The locking member 3 is in threaded cooperation with the support frame 24 so that the locking member 3 tightly abuts against the fixing plate 32.

[0038] An extension member 5 is fixedly connected to the side of the support frame 24 away from the sliding slot 21. One end of the extension member 5 away from the support frame 24 is hinged with a connecting member 51. The connecting member 51 is located at the bottom of the support frame 24. One end of the connecting member 51 away from the support frame 24 is threadedly connected with an adjusting rod 52, and the bottom of the adjusting rod 52 is fixedly connected with a support base 53.

[0039] After the support frame 24 is installed, rotate the connecting member 51 to expand the connecting member 51 outside the base 1, and adjust the adjusting rod 52 so that the support base 53 abuts against the operating ground, thereby providing further stable support for the lifting frame.

[0040] A connecting seat 6 is fixedly connected to the end of the support frame 24 away from the lifting platform 42. A universal wheel 61 is fixedly connected to the end of the connecting seat 6 away from the support frame 24. When moving the lifting frame, tilt the lifting frame so that the universal wheel 61 contacts the operating ground, which is convenient for moving the lifting frame.

[0041] To facilitate tilting the lifting frame, a handle 62 is fixedly connected to the side of the support frame 24 close to the connecting seat 6. The handle 62 is in a U shape, and the open end of the U shape is connected to the support frame 24.

[0042] One end of the lifting seat 4 away from the support frame 24 is fixedly connected with a support plate 43. The support plate 43 is located at the bottom of the lifting seat 4 and is used to support the lifting platform.

[0043] The implementation principle of a quick-release lifting frame according to an embodiment of the present application is as follows: When it is necessary to quickly disassemble the lifting frame, rotate the lifting platform 42 and fold the lifting platform 42 in the direction towards the support frame 24. One end of the lifting platform 42 away from the lifting seat 4 is placed on the support frame 24. Turn the locking member 3 to separate the locking member 3 from the support frame 24, and move the fixing plate 32 towards the end of the support frame 24 away from the base 23, so that the base 1 is folded in the direction towards the support frame 24. Rotate the connecting member 51 so that the connecting member 51 rotates in the direction towards the lifting platform 42. One end of the connecting member 51 away from the extension member 5 is placed on the base 1, thereby realizing the folding of the lifting frame. The lifting frame can be quickly disassembled and assembled. Pull the handle 62 to tilt the lifting frame, and the universal wheels 61 touch the ground, thereby moving the lifting frame, and further improving the quickness of disassembling and assembling the lifting frame.
