Description

Technical Field

[0001] This invention relates to the field of industrial production technology, and in particular to a semi-automatic hoisting, lifting and transporting device. Background Technology

[0002] With the rapid development of logistics warehousing, workshop production and construction, the demand for short-distance handling, lifting and hoisting of goods is becoming more and more frequent. Especially in confined spaces such as small spaces, indoor workshops and warehouse aisles, higher requirements are placed on the flexibility, multi-functionality and portability of handling equipment.

[0003] Currently, the most common small cargo handling equipment on the market mainly includes the following categories:

[0004] The first type is the ordinary four-wheeled cart, which has a simple structure and low cost, and is the most widely used short-distance transport tool. However, ordinary carts only have simple horizontal transport functions, rely entirely on manual pushing, which is labor-intensive, has limited load-bearing capacity, and cannot independently complete lifting operations when encountering steps, platforms, or other height differences, resulting in poor safety.

[0005] The second category is simple lifting equipment, such as manual hoists and simple cranes. This type of equipment can achieve vertical lifting of goods, but it does not have the function of horizontal transfer. It must be used in conjunction with transfer tools such as trolleys during operation. The operation process is cumbersome and inefficient. After the lifting is completed, the goods still need to be transferred to the target location manually or with the help of other tools. It cannot achieve integrated operation of lifting and transfer.

[0006] The third category is traditional forklifts and cranes. Although they have multiple functions such as lifting, handling, and hoisting, and have a strong load-bearing capacity, they are large in size, heavy in weight, and have a large turning radius. They cannot enter narrow indoor spaces, workshop aisles, elevator shafts, or other restricted areas for operation. In addition, they require a high level of professional expertise to operate and usually need to be driven by certified professionals. Their operating and maintenance costs are both high, making them unsuitable for short-distance handling of light goods weighing around 100 kilograms.

[0007] In summary, existing material handling equipment has limited functionality, failing to integrate hoisting, lifting, handling, and unloading into a single unit. This necessitates the use of multiple devices, resulting in cumbersome operation, low efficiency, high labor intensity, safety hazards, and increased costs and footprint associated with multiple units. Therefore, there is an urgent need for a semi-automatic hoisting and handling device to address the numerous shortcomings of existing technologies.

[0008] In view of this, the present invention is hereby proposed. Summary of the Invention

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] like Figures 1 to 4 As shown, the present invention provides a semi-automatic hoisting and lifting device, including a frame 1, a lifting mechanism, a base 4, a carrying platform 5, an unloading mechanism, and a hoisting mechanism; the lifting mechanism is mounted on the frame 1, and the base 4 is mounted on the output end of the lifting mechanism; the carrying platform 5 is hinged to the base 4, and the unloading mechanism is mounted between the base 4 and the carrying platform 5, for driving the carrying platform 5 to tilt and rotate relative to the base 4 to unload goods; the hoisting mechanism is rotatably mounted on the base 4 and located close to the unloading mechanism, for hoisting goods.

[0026] This invention integrates the lifting mechanism, unloading mechanism, and hoisting mechanism into one unit, effectively solving the technical problems of existing technologies where hoisting, handling, and unloading functions are separated, requiring multiple corresponding devices to cooperate, resulting in low operating efficiency, high labor intensity, and safety hazards. It realizes integrated semi-automatic operation of lifting, hoisting, and unloading, and is particularly suitable for indoor and outdoor short-distance handling scenarios of light-loaded goods weighing hundreds of kilograms in confined spaces.

[0027] As an optional implementation, a plurality of ball bearings 11 are provided on the upper surface of the support platform 5, and the ball bearings 11 are arranged in a matrix on the support platform 5.

[0028] Furthermore, the support platform 5 is made of high-strength steel plate. The balls of the ball bearing 11 protrude from the upper surface of the support platform 5. The ball bearing 11 includes a universal ball bearing.

[0029] After the goods are placed on the carrying platform 5, the bottom of the goods comes into direct contact with the balls of the ball bearing 11. The balls roll freely in the bearing housing of the ball bearing 11, which changes the sliding friction between the goods and the carrying platform 5 into rolling friction, thus reducing the coefficient of friction.

[0030] When it is necessary to adjust the position of the cargo on the carrying platform 5, the operator only needs to apply a small horizontal thrust, and the cargo can slide smoothly to the target position on the ball bearing 11.

[0031] When the carrying platform 5 is tilted for unloading, an inclination angle is formed between the carrying platform 5 and the horizontal plane. The cargo slides down the upper surface of the carrying platform 5 under its own weight. Since the bottom of the cargo is in direct contact with the balls of the ball bearing 11, the balls roll freely in the bearing seat. The cargo and the carrying platform 5 always maintain a rolling friction state. The coefficient of friction is low and the sliding resistance is minimal. No additional pushing force or manual lifting is required from the operator.

[0032] As an optional implementation, guardrails 12 are provided on both sides of the base 4. The guardrails 12 include multiple vertical sections 1201 and one horizontal section 1202. The vertical sections 1201 are arranged at intervals along the length of the guardrails 12. One end of each vertical section 1201 is hinged to the side plate of the guardrails 12, and the other end is hinged to the horizontal section 1202.

[0033] The vertical section 1201 is connected to the side plate and the horizontal section 1202 by hinges. Under normal operating conditions, all vertical sections 1201 are vertically extended and together with the horizontal section 1202 form a complete enclosure structure to prevent the goods on the carrying platform 5 from slipping during lifting or transfer.

[0034] As an optional implementation, a push-pull handrail 13 is provided on one end of the frame 1 near the hoisting mechanism. An inclined bracing mechanism is provided on both sides of the push-pull handrail 13. The inclined bracing mechanism includes an inclined bracing rod 14 and a support foot 15. One end of the inclined bracing rod 14 is hinged to the push-pull handrail 13, and the other end is connected to the support foot 15.

[0035] When the device is being moved, the diagonal brace 14 retracts upwards, and the support leg 15 is lifted off the ground, without affecting the normal movement of the transport device. When the device reaches the working position and needs to be lifted or hoisted, the operator extends the diagonal brace 14 downwards, and the support leg 15 touches the ground, forming a triangular support structure together with the push-pull handrail 13 and the bottom surface, which stably supports the transport device on the ground.

[0036] The diagonal bracing mechanism provides reliable triangular support for the handling device during operation, effectively preventing it from tipping over due to a rise in the center of gravity during lifting or uneven loading during hoisting, thus improving operational safety. Simultaneously, the diagonal bracing rod 14 is hinged to the push-pull handle 13, allowing for simple and quick unfolding and retraction. When not in use, it can be completely retracted without increasing the device's storage volume, facilitating storage.

[0037] The push-pull handle 13 is located at one end near the hoisting mechanism, so that the operator can naturally face the hoisting direction when pushing it, making it easier to observe the hoisting operation and making the operation more intuitive.

[0038] As an optional implementation, the lifting mechanism includes a scissor structure 2 and an electric cylinder 3. One end of the scissor structure 2 is hinged to the frame 1 and the other end is hinged to the base 4. The electric cylinder 3 is inclinedly disposed at the end of the frame 1 away from the lifting mechanism, and the telescopic end of the electric cylinder 3 is hinged to the scissor structure 2.

[0039] Furthermore, the scissor lift mechanism 2 is made of high-strength steel, and its lifting stroke is 200mm-600mm.

[0040] Compared to traditional hydraulic column-type lifting structures, the scissor lift structure 2 occupies less space and has a lower overall height when retracted, making the handling device shorter and easier to store when not in use. The electric cylinder 3 drives the lifting mechanism, replacing the traditional manual hydraulic lifting, enabling electric lifting. Operators no longer need to manually operate the hydraulic valves; they only need to press the corresponding operation button 20 on the electrical control box 22 to control the lifting, reducing labor intensity.

[0041] When lifting or lowering is required, the control box 22 sends a command to the electric cylinder 3, which extends or retracts the telescopic end of the electric cylinder 3, driving the scissor lift structure 2 to unfold or retract, thereby causing the base 4 and the support platform 5 to rise or fall.

[0042] As an optional implementation, the unloading mechanism includes an electric push rod 21, which is mounted on the base 4, and the telescopic end of the electric push rod 21 is fixedly connected to the bearing platform 5.

[0043] Furthermore, the telescopic stroke of the electric actuator 21 is 50mm. The maximum tilt angle of the support platform 5 is 20 degrees.

[0044] When unloading is required, the operator presses the corresponding operation button 20 on the control box 22 to send a command to the electric push rod 21. The telescopic end of the electric push rod 21 extends, pushing the carrying platform 5 to tilt upward around its hinge point with the base 4, so that the goods on the carrying platform 5 automatically slide out under the action of gravity, completing the unloading. After unloading is completed, the telescopic end of the electric push rod 21 retracts, and the carrying platform 5 returns to a horizontal state under its own weight.

[0045] This invention uses an electric push rod 21 to drive the carrying platform 5 to tilt and unload goods, replacing the traditional manual tilting or unloading method. This achieves rapid electric unloading, allowing operators to complete the unloading operation without touching the goods. It is especially suitable for unloading heavy objects or goods that are inconvenient to handle manually. This design results in fast unloading speed, smooth operation, and avoids the risk of goods falling or being damaged due to uneven force during manual tilting, thus ensuring high safety.

[0046] As an optional implementation, the lifting mechanism includes a rotary servo motor 6, a worm gear assembly 7, a rotating arm 8, a traveling structure 9, and a lifting structure 10. The rotary servo motor 6 is mounted on the base 4, and its output end is connected to the worm gear. The worm gear meshes with the worm wheel for transmission, and the worm wheel is connected to the rotating arm 8 for driving the rotating arm 8 to rotate. A traveling track 801 is provided on the rotating arm 8, which extends horizontally. The traveling structure 9 drives the lifting structure 10 to move along the traveling track 801, and the lifting structure 10 is used to lift goods.

[0047] Furthermore, a limit trigger is provided on the base 4 or the rotating arm 8, and a limit sensor is provided on the rotating arm 8 or the base 4. When the rotating arm 8 rotates to the limit position, the limit trigger and the limit sensor cooperate to trigger, so as to avoid the rotating arm 8 from rotating excessively.

[0048] The rotary servo motor 6, in conjunction with the worm gear assembly 7, drives the rotating arm 8 to rotate. The worm gear transmission has excellent self-locking characteristics, meaning that after the rotary servo motor 6 stops driving, the rotating arm 8 will not rotate due to the weight of the cargo or external forces, improving safety during the lifting process and eliminating the need for an additional braking device. Simultaneously, the large transmission ratio of the worm gear allows the lifting structure 10 to be precisely positioned to the required angle.

[0049] The walking structure 9 adopts the existing electric walking trolley structure, which includes a walking servo motor, a gearbox and walking rollers. The walking servo motor drives the walking rollers to rotate through the gearbox. The walking rollers roll in cooperation with the walking track 801 on the rotating arm 8, driving the lifting structure 10 to move precisely in the horizontal direction.

[0050] The lifting structure 10 uses an existing mini electric hoist, which is suspended at the bottom of the traveling structure 9. The mini electric hoist includes a lifting servo motor, a reducer, a drum, and a wire rope. The lifting servo motor is located at the bottom of the traveling structure 9, and its output end is connected to the drum via the reducer. The wire rope is wound on the drum, and the end of the wire rope is equipped with a hook for hanging goods, which can realize precise vertical lifting and lowering of goods.

[0051] As an optional implementation, a moving mechanism is provided at the bottom of the frame 1. The moving mechanism includes a moving servo motor 16, an electromagnetic clutch 17, directional wheels 18, and omnidirectional wheels 19. There are two sets of directional wheels 18, which are symmetrically arranged on the bottom surface of the frame 1 near the hoisting mechanism and are respectively connected to the moving servo motor 16 through the electromagnetic clutch 17. There are two sets of omnidirectional wheels 19, which are symmetrically arranged on the bottom surface of the frame 1 away from the hoisting mechanism.

[0052] Furthermore, the frame 1 is formed by welding square tubes to form a square frame, and the directional wheels 18 and omnidirectional wheels 19 are respectively set at the four corners of the bottom of the frame 1.

[0053] When the servo motor 16 is needed to assist in the transfer, the electromagnetic clutch 17 is engaged, and the power of the servo motor 16 is transmitted to the directional wheel 18 through the electromagnetic clutch 17. The servo motor 16 drives the directional wheel 18 to rotate, which in turn drives the conveying device to travel smoothly in a straight line. The omnidirectional wheel 19 follows the steering.

[0054] When manual pushing is required, the electromagnetic clutch 17 disengages, the mobile servo motor 16 does not participate in driving, and the two sets of directional wheels 18 and the two sets of universal wheels 19 roll freely. The operator can easily push the device by pushing and pulling the handle 13, and the steering is flexible.

[0055] The combined arrangement of the directional wheels 18 and the omnidirectional wheels 19 achieves a front-directional and rear-omnidirectional steering layout, making the conveying device stable and controllable in straight-line travel when electrically driven, and flexible and easy to steer when manually pushed. When the electromagnetic clutch 17 is engaged, the mobile servo motor 16 drives the directional wheels 18 to achieve electrically assisted transfer, reducing the labor intensity of the operator. When the electromagnetic clutch 17 is disengaged, the mobile servo motor 16 is completely disengaged from the directional wheels 18, and the directional wheels 18 and the omnidirectional wheels 19 roll freely, allowing the operator to easily push the device.

[0056] This design balances the stability of electric drive with the flexibility of manual pushing, and the engagement and disengagement of the electromagnetic clutch 17 can be switched with one button via the control box 22, making operation convenient.

[0057] As an optional implementation, an electrical control box 22 is also included. The electrical control box 22 is mounted on the frame 1 and is electrically connected to the moving mechanism, lifting mechanism, unloading mechanism, rotating mechanism and hoisting mechanism respectively.

[0058] Furthermore, it also includes multiple operation buttons 20, which are set on the push-pull handrail 13 and electrically connected to the electrical control box 22 respectively. Each operation button 20 is used to issue control commands to control the extension and retraction of the electric cylinder 3 of the lifting mechanism, the extension and retraction of the electric push rod 21 of the unloading mechanism, the forward and reverse rotation of the rotary servo motor 6 of the rotating mechanism, the forward and reverse rotation of the traveling servo motor in the hoisting mechanism, the forward and reverse rotation of the lifting servo motor in the hoisting mechanism, the forward and reverse rotation of the moving servo motor 16 in the moving mechanism, and the engagement and disengagement of the electromagnetic clutch 17.
