Description

Technical Field

[0001] This invention relates to a convenient, efficient, and impact-resistant vertical lifting power device and its lifting method, belonging to the field of mechanical equipment. Background Technology

[0002] Lifting and adjusting devices are widely used in mechanical equipment that requires vertical lifting power. Currently, common lifting devices on the market mainly include hydraulic lifting devices, screw lifting devices, rack and pinion lifting devices, and electric push rod lifting devices.

[0003] While hydraulic lifting devices offer significant lifting power, their ability to maintain the lifting height is poor, typically requiring a separate pressure-holding device, resulting in a cumbersome and complex system structure. Screw-driven lifting devices are mostly suitable for horizontal adjustments, but their load-bearing capacity is poor under heavy vertical lifting conditions. Rack and pinion lifting devices have relatively weak impact resistance and require significant drive torque during the lifting stroke. Electric pushrod lifting devices can achieve precise feeding, but their impact resistance is also poor, making it difficult to meet impact-resistant application requirements.

[0004] Therefore, existing lifting devices cannot simultaneously achieve convenience, efficiency, and impact resistance in vertical lifting power applications. There is an urgent need for a new type of lifting power device that is structurally sound, easy to operate, has a fast lifting speed, and can withstand impact loads. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a convenient, efficient, and impact-resistant vertical lifting power device and its lifting method. The technical solution of this invention is as follows: A convenient, efficient, and impact-resistant vertical lifting power device, comprising: Lifting guide rail frame (5); Mounting base assembly (3) is slidably mounted on the lifting guide rail (5); The drive assembly (4) is rotatably mounted on the lifting guide rail (5) and threadedly engaged with the mounting base assembly (3) to drive the mounting base assembly (3) to move up and down along the lifting guide rail (5); The handwheel (7) is mounted on the drive assembly (4) and is used to input rotational driving force; The guide rail cover (1) is fixedly installed on the upper part of the lifting guide rail (5); Bearing (2), one bearing (2) is installed on the upper part and the lower part of the lifting guide rail (5), and the drive assembly (4) is rotatably mounted on the lifting guide rail frame (5) through the bearing (2), wherein the upper bearing (2) is covered by the guide rail cover (1). Anti-collision block (8) is installed on the inner side of the lower part of the lifting guide rail frame (5) to buffer the mounting seat assembly (3) when the mounting seat assembly (3) descends; The positioning pin (6) has a positioning pin hole on the side of the lifting guide rail frame (5) and a mounting seat positioning hole on the mounting seat assembly. When the positioning pin (6) passes through the positioning pin hole and the mounting seat positioning hole in sequence, the mounting seat assembly (3) is locked.

[0006] The mounting bracket assembly (3) includes: a mounting bracket (B); A track wheel (A) is mounted on the mounting base (B) and rolls in cooperation with the rolling groove of the lifting guide frame (5). Each track wheel (A) has a flat washer (F) and a spring washer (E) sequentially fitted on its axle. After the axle of the track wheel (A) passes through the side plate of the lifting guide frame (5), a first nut (D) and a second nut (C) are sequentially installed. The second nut (C) is a lock nut.

[0007] The positioning pin (6) is used to lock the mounting assembly (3) by passing through the positioning pin hole and the mounting positioning hole when the mounting assembly (3) is raised or lowered to the required stroke position.

[0008] The drive assembly (4) includes a lead screw and a lead screw nut mounted on the lead screw. The lead screw is rotatably mounted on the guide rail lifting frame (5) via a bearing (2). The lower end of the lead screw extends out of the guide rail lifting frame (5) and is fitted with the handwheel (7). The lead screw nut is detachably connected to the mounting base assembly (3).

[0009] The lead screw of the drive assembly (4) and the track wheel (A) form a joint force-bearing structure, and the load during the vertical lifting process is borne by both of them.

[0010] The mounting base assembly (3) is detachably connected to the lifting guide rail frame (5).

[0011] The lifting guide rail (5) is suitable for installation on round tubes, square tubes or walls of various specifications to adapt to different target equipment.

[0012] The handwheel (7) drives the lead screw by rotating clockwise or counterclockwise, thereby enabling the vertical lifting and lowering of the mounting bracket assembly (3).

[0013] The mounting bracket assembly includes a front panel, a top plate, a bottom plate, and side plates. The front panel is arranged vertically and has a window. A side plate is provided on each side of the front panel, and each side plate is generally arranged in an "n" shape. The mounting bracket positioning hole is provided on the side plate. The top plate and the bottom plate are provided with lead screw holes for lead screws to pass through. The top plate is installed on the upper part of the front panel, and the bottom plate is installed on the lower part. The bottom plate, top plate, front panel, and side plates together form a frame structure.

[0014] A lifting method based on the aforementioned convenient, efficient, and impact-resistant vertical lifting power device includes the following steps: S1. Install the target device to be lifted onto the mounting base assembly (3); S2: By rotating the handwheel (7) clockwise or counterclockwise, the drive assembly (4) is driven to rotate, thereby driving the mounting base assembly (3) to rise and fall vertically along the lifting guide rail (5) to the required height; S3. Pass the positioning pin (6) through the positioning pin hole on the side of the lifting guide rail frame (5) and the mounting seat positioning hole on the mounting seat assembly (3) in sequence, and lock the mounting seat assembly (3) in the current position. S4. When it is necessary to lower, pull out the positioning pin (6) and rotate the handwheel (7) in the opposite direction to lower the mounting base assembly (3); when the mounting base assembly (3) is lowered to the lowest position, the anti-collision block (8) buffers the mounting base assembly (3).

[0015] The advantages of this invention are: 1. Upon reaching the desired travel position, the device is effectively locked using a locating pin. This mechanical locking method is superior to existing electric motor locking methods on the market, providing reliable safety. It also features a drop-proof safety design; in the event of equipment damage and a fall, the impact block will cushion the impact, effectively preventing safety issues for people and animals.

[0016] 2. The combined force-bearing design of the lead screw and guide wheels eliminates the problem of the workpiece being subjected to force alone, forming a good combined force-bearing form. This reduces impact damage to individual components and improves the service life of the device. At the same time, the lead screw has good impact resistance, and the lifting performance will not be affected during use; the guide wheels and guide rails adopt a heavy-duty structural design, which has high impact resistance, thus greatly ensuring the durability of the entire device.

[0017] 3. This lifting device can be used for any type or specification of lifting target equipment, making it highly applicable and flexible in configuration.

[0018] 4. Flexible application and installation scenarios, suitable for various specifications of round pipes, square pipes, and walls, and simple and convenient installation; 5. Simple to use and operate; rapid raising and lowering can be achieved by turning the handwheel clockwise or counterclockwise. When adjusted to the desired position, it can be quickly locked using the positioning pin; convenient for quick disassembly and assembly, facilitating after-sales replacement. 6. It has a fast lifting speed and requires little torque, saving time and effort, and can quickly adjust the height of the equipment. Attached Figure Description

[0025] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer as a result. However, these embodiments are merely exemplary and do not constitute any limitation on the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solutions of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0026] See Figures 1 to 6This invention relates to a convenient, efficient, and impact-resistant vertical lifting power device, comprising: a lifting guide rail frame 5; a mounting base assembly 3, slidably mounted on the lifting guide rail 5; a drive assembly 4, rotatably mounted on the lifting guide rail frame 5 and threadedly engaged with the mounting base assembly 3, for driving the mounting base assembly 3 to move up and down along the lifting guide rail frame 5; a handwheel 7, mounted on the drive assembly 4, for inputting rotational driving force; a guide rail cover 1, fixedly mounted on the upper part of the lifting guide rail 5; and bearings 2, respectively mounted on the upper and lower parts of the lifting guide rail 5. The bearing 2 and drive assembly 4 are rotatably mounted on the lifting guide rail frame 5 via the bearing 2, wherein the upper bearing 2 is covered by the guide rail cover 1; the anti-collision block 8 is installed on the inner side of the lower part of the lifting guide rail frame 5 to buffer the mounting seat assembly 3 when it descends; the positioning pin 6 has a positioning pin hole on the side of the lifting guide rail frame 5 and a mounting seat positioning hole on the mounting seat assembly. When the positioning pin 6 passes through the positioning pin hole and the mounting seat positioning hole in sequence, it locks the mounting seat assembly 3.

[0027] The positioning pin 6 passes through the positioning pin hole on the side of the lifting guide rail frame 5 and the mounting seat positioning hole on the mounting seat assembly 3 to achieve rigid locking; at the same time, the anti-collision block 8 on the lower inner side of the lifting guide rail frame 5 provides cushioning when the mounting seat assembly 3 descends to the lowest position or falls accidentally, so as to avoid injury to people and animals.

[0028] The lead screw of the drive assembly 4 and the track wheel A in the mounting base assembly 3 form a joint force-bearing structure. The load during vertical lifting is borne by both of them, reducing impact damage to individual parts and extending the service life of the device.

[0029] The handwheel 7 is mounted on the drive assembly 4. By rotating clockwise or counterclockwise, it directly drives the lead screw, which in turn drives the mounting base assembly 3 to move up and down quickly along the lifting guide rail 5. It requires little torque and saves time and effort.

[0030] The mounting bracket 3 and the lifting guide rail 5 are detachably connected, which facilitates quick disassembly, quick installation and after-sales replacement; the lifting guide rail 5 is suitable for installation on various specifications of round tubes, square tubes or walls, and can flexibly adapt to different target equipment and scenarios.

[0031] The track wheel A of the mounting base assembly 3 rolls in conjunction with the rolling groove of the lifting guide rail 5 to ensure smooth lifting.

[0032] The mounting base assembly 3 includes: a mounting base B; a track wheel A, which is mounted on the mounting base B and rolls in cooperation with the rolling groove of the lifting guide rail frame 5; each track wheel A has a flat washer F and a spring washer E sequentially fitted on its axle, and after the axle of the track wheel A passes through the side plate of the lifting guide rail frame 5, a first nut D and a second nut C are sequentially installed, and the second nut C is an anti-loosening nut.

[0033] The track wheel A and the rolling groove of the lifting guide rail 5 form a rolling engagement, which transforms sliding friction into rolling friction, significantly reducing lifting resistance and ensuring that the vertical lifting process of the mounting base assembly 3 is stable, smooth and efficient.

[0034] Each track wheel axle is fitted with a flat washer F and a spring washer E in sequence. After the axle passes through the side plate, the first nut D and the second nut C are installed in sequence. The second nut is a lock nut. Together with the spring washer, they form a triple lock mechanism to effectively resist vibration and impact during the lifting process and prevent the nut from loosening.

[0035] The positioning pin 6 is used to lock the mounting base assembly 3 by passing through the positioning pin hole and the mounting base positioning hole when the mounting base assembly 3 is raised or lowered to the required stroke position. When the mounting base assembly 3 is raised or lowered to the required stroke position, the positioning pin 6 can pass through the positioning pin hole on the side of the lifting guide rail frame 5 and the mounting base positioning hole on the mounting base assembly at the same time, so as to achieve mechanical rigid locking, effectively overcome the defect of the screw drive not being able to self-lock, and ensure that the target equipment can be stably stopped at any height.

[0036] The insertion and removal of the positioning pins are simple and quick, requiring no auxiliary tools to lock and unlock, facilitating rapid height adjustment; at the same time, the pin hole mating method provides precise positioning, with no relative slippage after locking, providing reliable safety for the device.

[0037] The drive assembly 4 includes a lead screw and a lead screw nut 42 mounted on the lead screw 41. The lead screw is rotatably mounted on the guide rail lifting frame 5 via a bearing 2. The lower end of the lead screw extends out of the guide rail lifting frame 5 and is fitted with the handwheel 7. The lead screw nut is detachably connected to the mounting base assembly 3.

[0038] The lead screw of the drive assembly 4 and the track wheel A form a joint force-bearing structure, and the load during the vertical lifting process is borne by both of them.

[0039] By sharing the load during vertical lifting between the lead screw and the track wheel, the load is prevented from being applied entirely to a single component, such as the lead screw or the track wheel. This effectively reduces stress concentration and impact damage to individual parts, thereby significantly improving the overall durability of the device.

[0040] The combined load-bearing structure allows the lead screw to primarily bear the axial lifting force, while the track wheel simultaneously bears the radial guiding force and part of the vertical load. The two work together to improve the structural stability of the device when subjected to large loads or sudden impacts, ensuring a smooth and reliable lifting process.

[0041] The mounting base assembly 3 is detachably connected to the lifting guide rail frame 5.

[0042] The lifting guide rail 5 is suitable for installation on round tubes, square tubes, or walls of various specifications to adapt to different target equipment.

[0043] The handwheel 7 drives the lead screw by rotating clockwise or counterclockwise, thereby achieving the vertical lifting and lowering of the mounting base assembly 3. The lifting guide rail 5 is compatible with various substrate forms such as round tubes, square tubes, and walls, eliminating the need to redesign or replace the guide rail for different installation environments, and greatly improving the adaptability of the device during on-site deployment.

[0044] The mounting bracket assembly includes a panel 31, a top plate 33, a bottom plate 34, and side plates 32. The panel 31 is vertically oriented and has a window 35. A side plate 32 is located on each side of the panel 31, and each side plate 32 is generally n-shaped. The mounting bracket positioning hole is located on the side plate 32. The top plate 33 and bottom plate 34 have lead screw holes for the lead screw 41 to pass through. The top plate 33 is installed on the upper part of the panel 31, and the bottom plate 34 is installed on the lower part. The bottom plate 34, top plate 33, panel 31, and side plates 32 together form a frame structure. This frame structure, formed by the bottom plate, top plate, panel, and two n-shaped side plates, effectively controls weight while ensuring overall rigidity and torsional resistance. The window 35 on the panel facilitates observation of the internal lead screw operation or reduces weight, achieving a balance between structural strength and ease of use.

[0045] The mounting holes on the side plate 32 are used to lock with the positioning pins, and the screw holes on the top plate 33 and bottom plate 34 are used to pass through the screw 41. Each component has a specific function and corresponding position, so that the screw drive and the locking mechanism do not interfere with each other. The frame structure also provides a stable mounting base for the track wheel, ensuring that the lifting process is smooth and reliable.

[0046] This invention also relates to a lifting method based on the aforementioned convenient, efficient, and impact-resistant vertical lifting power device, comprising the following steps: S1. Install the target device to be lifted onto the mounting base assembly 3; S2: By rotating the handwheel 7 clockwise or counterclockwise, the drive assembly 4 is driven to rotate, thereby driving the mounting base assembly 3 to rise and fall vertically along the lifting guide rail 5 to the required height; S3. Pass the positioning pin 6 through the positioning pin hole on the side of the lifting guide rail frame 5 and the mounting seat positioning hole on the mounting seat assembly 3 in sequence, and lock the mounting seat assembly 3 in the current position; S4. When it is necessary to lower the mounting base, pull out the positioning pin 6 and rotate the handwheel 7 in the opposite direction to lower the mounting base assembly 3; when the mounting base assembly 3 is lowered to the lowest position, the anti-collision block 8 cushions the mounting base assembly 3.

[0047] Step S1 involves directly installing the target equipment to be lifted onto the mounting base assembly 3. Utilizing the detachable connection between the mounting base assembly and the lifting guide rail frame, different types and specifications of target equipment can be quickly replaced or adapted without the need for special tools.

[0048] Step S2 drives the drive assembly 4 to rotate by rotating the handwheel 7 clockwise or counterclockwise, thereby driving the mounting base assembly 3 to rise and fall vertically along the lifting guide rail 5. The handwheel drive method requires no electricity, has low torque, fast lifting speed, and can control the lifting height at will.

[0049] Step S3: Pass the positioning pin 6 through the positioning pin hole on the side of the lifting guide rail frame 5 and the mounting seat positioning hole on the mounting seat assembly 3 in sequence, and lock the mounting seat assembly in the current position. The mechanical positioning pin locking overcomes the defect that the lead screw cannot self-lock, ensuring that the target equipment is stable and does not fall at the working height.

[0050] After pulling out the positioning pin 6 in step S4, rotate the handwheel 7 in the opposite direction to lower the mounting base assembly 3. When it is lowered to the lowest position, the anti-collision block 8 cushions the mounting base assembly to avoid hard impact and protect the safety of the device and the operator.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
