Description

Technical Field

[0001] This utility model relates to a hanging device, and more particularly to a suspension assist device. Background Technology

[0002] Nowadays, both the logistics and manufacturing industries rely heavily on lifting devices to assist workers in lifting and moving heavy objects. Most current lifting devices are traditional overhead crane structures, which mainly consist of a gantry frame, a trolley, and a lifting device. The top of the gantry frame has a track, on which the trolley can move. The lifting device is connected to the trolley and has chains and hooks hanging down. By operating the controller, the operator can control the movement of the trolley and also control the raising and lowering of the lifting device, thereby assisting workers in lifting or lowering heavy objects.

[0003] However, in the aforementioned hoisting operations, when the goods are hoisted, the operator needs to maintain the stability of the goods while simultaneously operating the controller. The overall operation process is not smooth and is mentally and physically demanding. The operator is easily distracted, which can lead to workplace safety hazards. If one person stabilizes the goods while the other operates the controller, constant communication is required, which not only prolongs the operation time but also poses a danger if misunderstandings or misinterpretations occur during communication. In addition, some hoisting operations require weighing the goods at the same time, which adds an extra step of lowering the goods for weighing, thus prolonging the operation time and affecting production efficiency. Therefore, the existing hoisting devices have the aforementioned problems and shortcomings in their overall structure and need to be improved. Utility Model Content

[0004] In view of the shortcomings and deficiencies of the existing technology, the present invention provides a suspension assist device, which uses a base to install a drive device, a reducer, a chain and a control device to assist the user in exerting force to hang heavy objects.

[0005] To achieve the above objectives, the technical means adopted by this utility model is to design a suspension assist device, which includes:

[0006] A base having a top surface and a bottom surface, the base having a front through hole and a rear through hole, the top surface having a mounting part having a front mounting hole and a rear mounting groove, the front mounting hole having a lateral through-hole, the rear mounting groove being recessed into one side of the mounting part, and the mounting part having a hook.

[0007] A drive device, which passes through and is fixed to the front mounting hole of the mounting part;

[0008] A speed reducer having a sprocket and a drive wheel, the speed reducer being disposed in the rear mounting slot and connected to the drive wheel and the drive device by a belt;

[0009] A chain having a front end and a rear end, the front end being connected to a weighing sensor, a hanging member being connected below the weighing sensor, the chain passing through the front end through the front hole and the rear end through the rear hole, and the chain being wound around the sprocket.

[0010] A control device is disposed on the base and located on the other side of the mounting portion opposite to the reducer, the control device being electrically connected to the drive device and the weighing sensor.

[0011] Furthermore, the suspension assist device further includes a front buffer, one end of which is connected above the weighing sensor, and the other end of which is connected to the front end of the chain.

[0012] Furthermore, the suspension assist device further includes a rear buffer connected to the rear end of the chain.

[0013] Furthermore, in the aforementioned suspension assist device, the front mounting hole of the mounting portion is located adjacent to the upper front side.

[0014] Furthermore, in the aforementioned suspension assist device, the rear mounting slot of the mounting portion is located adjacent to the lower rear side.

[0015] Furthermore, in the aforementioned suspension assist device, the inner wall of the rear mounting groove is provided with two chain holes, which extend toward the bottom surface and are respectively connected to the front through hole and the rear through hole, and the chain passes through the two chain holes.

[0016] Furthermore, in the aforementioned suspension assist device, the front buffer is a spring.

[0017] Furthermore, in the aforementioned suspension assist device, the rear damper is a spring.

[0018] Furthermore, the suspension assist device includes a control device comprising a servo driver and a power supply, the power supply being electrically connected to the servo driver, the drive device, and the weighing sensor.

[0019] The advantages of this invention are that users can set the auxiliary force to assist in lifting heavy objects, allowing for independent operation and significantly reducing physical exertion, thus improving work efficiency. During the lifting process, when the user stops exerting force, the heavy object is suspended at its current position, thereby enhancing overall work safety and preventing the user from being crushed by the heavy object and causing workplace accidents. Furthermore, the counterweight ensures that the overall center of gravity is close to the center, achieving balance in both left-right and front-back directions. This enhances the stability of the invention when suspending heavy objects and prevents eccentric swaying. Attached Figure Description

[0030] Please see Figures 1 to 3 As shown, the suspension assist device of this utility model includes a base 10, a drive device 20, a reducer 30, a chain 40 and a control device 50.

[0031] Please see Figure 3 , Figure 4 and Figure 8As shown, the base 10 is a plate having a top surface 11 and a bottom surface 12. The base 10 has a front through hole 13 and a rear through hole 14, which are located in the front-rear direction of the base 10, respectively. In a preferred embodiment, the front through hole 13 is located at the center of the base 10, but this is not a limitation. A mounting portion 15 is disposed on the top surface 11 of the base 10, preferably at the center. The mounting portion 15 is an upright plate-like structure, forming a front mounting hole 151 and a rear mounting groove 152. The front mounting hole 151 laterally penetrates the mounting portion 152. 5. The rear mounting groove 152 is recessed into one side of the mounting part 15 and is located near the rear side near the bottom. The inner wall of the rear mounting groove 152 is provided with two chain holes 153. The two chain holes 153 pass through the bottom surface 12 and are respectively connected to the front through hole 13 and the rear through hole 14. A hook 154 or a structure for hanging is provided at the upper position of the mounting part 15, and it can be covered by a housing 16. However, it is not limited to the above. The structure of the base 10 can be changed according to the user's needs, and the housing 16 may not be provided.

[0032] Please see Figures 3 to 7 As shown, the drive device 20 passes through the front mounting hole 151 fixed to the mounting part 15. In this embodiment, the drive device 20 is a servo motor. Its preferred installation method is a balanced setting with the center of gravity concentrated in the mounting part 15, but it is not limited thereto.

[0033] The reducer 30 has a sprocket 31 and a drive wheel 32. The reducer 30 is disposed in the rear mounting groove 152 of the mounting part 15, and is connected to the drive wheel 32 and the drive device 20 by a belt 33. Specifically, the side of the reducer 30 with the sprocket 31 is located in the rear mounting groove 152, and the drive wheel 32 is located outside the rear mounting groove 152. The reducer 30 in this embodiment is a harmonic reducer, which is a standard component of the prior art. Its detailed structure will not be described in detail, but it is not limited thereto.

[0034] The chain 40 has a front end 41 and a rear end 42. The front end 41 is connected to a weighing sensor 43, a hanging member 44 and a front buffer 45. The weighing sensor 43 is a load cell used to sense weight. One end of the hanging member 44 is connected to one end of the weighing sensor 43. The front buffer 45 is a spring, one end of which is connected to the other end of the weighing sensor 43. The other end of the front buffer 45 is connected to the chain 40. The rear end 42 is connected to a rear buffer 46, which is also a spring. The chain 40 is wound around the sprocket 31 and passes through the chain hole 153. The chain 40 passes through the front hole 13 with the front end 41 and the rear hole 14 with the rear end 42. However, it is not limited to the above, and the front buffer 45 or the rear buffer 46 may not be provided.

[0035] The control device 50 is disposed on the base 10 and located on the other side of the mounting part 15 opposite to the reducer 30. The control device 50 is electrically connected to the drive device 20 and the weighing sensor 43. In this embodiment, the control device 50 includes a servo driver 51 and a power supply 52. ​​The power supply 52 is electrically connected to the servo driver 51, the drive device 20 and the weighing sensor 43. The servo driver 51 and the power supply 52 are standard components of the prior art, and their detailed structure will not be described in detail, but they are not limited thereto. The control device 50 can be changed according to the user's needs.

[0036] When using this utility model, please refer to [link / reference]. Figure 9 As shown, the user can use a processor 60 to read data, set the load-bearing value of the drive device 20, or perform an emergency stop. The aforementioned functions are existing technology and will not be described in detail. For example, when the user wants to suspend a 100 kg load, the processor 60 can set the auxiliary output of this utility model to 98 kg. Therefore, when the user lifts the load, the weight sensor 43 senses the weight of the load and sends a signal back to the control device 50 and the processor 60, driving the drive device 20 to start the auxiliary lifting output of 98 kg. The user only needs to exert 2 kg of force to lift the load, thereby achieving the effect of this utility model assisting the user in exerting force, so that the user can operate independently and greatly reduce physical exertion, improving work efficiency. During the lifting process, when the user stops exerting force, this utility model can use the weight sensor 43 to sense and then supplement the force to 100 kg, so that the load is suspended at the current position, thereby improving the overall safety of the operation and preventing the user from being crushed by the heavy load and causing industrial safety hazards.

[0037] In the aforementioned process, the installation unit 15 arranges the positions of the drive device 20 and the reducer 30 according to the weight of each component. Then, by adjusting the position of the control device 50, the overall center of gravity of this utility model is brought closer to the central position after the counterweight is applied, so that the balance effect is achieved in both left and right or front and back directions. This improves the stability of this utility model when suspending heavy objects and avoids eccentric swaying when suspending heavy objects.

[0038] In the aforementioned process, the front buffer 45 and the rear buffer 46 can provide limits and buffers during suspension. Specifically, the bottom dead center or top dead center position of the chain 40's movement path is set by the front buffer 45 and the rear buffer 46. When it is lifted to the point of contact with the front buffer 45, it is the top dead center of the movement path. When it is lowered to the point of contact with the rear buffer 46, it is the bottom dead center of the movement path. The front buffer 45 or the rear buffer 46 can also achieve the effect of collision buffering to prevent the mechanism from being damaged by collision.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Anyone skilled in the art can make some modifications or alterations to the above-disclosed technical content as equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
