Winch capable of being externally connected with motor to increase power

[ technical field ] A method for producing a semiconductor device

The present invention relates to a winch, and more particularly to a winch that can be externally connected to a motor to increase overall power and provide a wider applicable range.

[ background of the invention ]

Winches (also known as power winches) are power tools designed for use in hoisting or hauling loads, such as most commonly: the hoisting winch for vertically lifting the goods (heavy) hung on the high-rise building is a winch; the rope winding machine is also a winch and is arranged in front of a jeep or an off-road vehicle and used for dragging other vehicles, other objects or other people to move and escape from danger. The winch has the action principle that a power source (such as a power motor and an electric motor) outputs forward or reverse transmission power, a rope wheel is driven to rotate forward or reversely after the action of a speed reducing mechanism, so as to send out or withdraw a rope (a steel rope or a synthetic rope, but not limited), and the front end of the rope (the steel rope or the synthetic rope) is hooked on a load (a heavy object, other vehicles or other objects and the like) by a hammer weight hook head so as to move the load.

There are many types of conventional winches, one of which is a conventional winch 10, as shown in fig. 1, the winch 10 has a motor 11 on one side, the power output from the motor 11 is transmitted through an internal shaft center to drive a transmission device 12 on the other side, and the transmission device 12 drives a rope pulley 13 to rotate after being transmitted and decelerated by a plurality of planetary gear sets, so that a rope (steel rope or synthetic rope, not shown) wound around the rope pulley 13 can be released or retracted; a clutch device 14 is arranged in the speed reducer 12 at one side of the cable pulley 13, a handle extends upwards from the outside, and the handle is manually operated to descend or ascend, so that the transmission connection or disconnection between the cable pulley 13 and the speed reducer 12 can be realized through the action of the clutch device 14; the cable pulley 13 is supported by a fixed seat 15 so that the whole power winch 10 can drive stably and smoothly. The conventional winch 10 may be referred to as a "single motor type winch".

Since winches are power tools used for hoisting or pulling loads, the single motor type winch is limited to a single motor, and the torque that can be applied and the pulling force and pulling speed that can be generated are limited, and a double motor type winch has been developed to increase the torque of the whole winch and increase the pulling force and pulling speed. A winch 20 of the dual-motor type, as shown in fig. 2 and 3, the winch 20 has a transmission case 33, a set of stationary motors 31 and 32 is assembled at one side of the exterior of the transmission case 33, the power output by the motors 21 and 22 is transmitted into the transmission case 23, and then jointly drives a transmission device (not shown) arranged in the transmission case 23 to act, so as to drive a rope pulley 24 arranged below the motors 21 and 22 to rotate, so that a rope (steel rope or synthetic rope, not shown) wound around the rope pulley 24 can be controlled by the power to perform the action of releasing or retracting the rope (steel rope or synthetic rope) when necessary; the cable pulley 24 is supported by a support base 25, and the transmission device in the transmission device box 23 mainly reduces the speed of the power appropriately to drive the cable (steel cable or synthetic cable) to be released or retracted. The double-motor type winch 20 is formed by combining two motors 21 and 22 on one (inner) side of a transmission box 23, the appearance of the transmission box 23 is complete, particularly the top surface is flat without any exposed components, then a supporting seat 25 supports a cable pulley 24 and is jointly assembled on the same side of the transmission box 23 and combined below the two motors 21 and 22, the whole winch 20 has tight combination, and obviously is a power machine. Since the dual-motor winch 20 is driven by two motors simultaneously to act on the transmission device and provide double torque to the cable pulley 24, compared with the single-motor winch, the dual-motor winch 20 can provide a larger pulling force and a faster pulling speed to the cable pulley 24, so that the dual-motor winch 20 is suitable for use in a higher load and a more severe environment, in other words, the dual-motor winch 20 can increase the overall power to provide a wider application range.

The external motor 40 and the transmission case 33 are combined as shown in fig. 6-8, the front end of the output shaft of the external motor 40 is connected with an output gear 43 inside the front housing 41, the lower part of the output gear 43 is engaged with an intermediate gear 44, the output gear 43 and the intermediate gear 44 are both arranged inside the front housing 44, the lower part of the front housing 41 is open, so the intermediate gear 44 is exposed in the bottom surface of the front housing 41, the front and rear sides of the bottom of the front housing 41 extend outwards to form a joint wall body 411, and the joint wall body 411 is provided with joint through holes 412; an opening 331 is provided on the top surface of the transmission device case 33, a transmission gear 332 for receiving engagement is provided in the opening 331, the front and rear ends of the axis of the transmission gear 332 are supported by bearings and are provided between the two sidewall bodies of the transmission device case 33, so that a little part of the gear body of the transmission gear 332 penetrates out of the opening 331; the front and rear side walls of the top surface of the opening 331 are respectively provided with a connection screw hole 3311 corresponding to the connection through hole 412, the top surface of the opening 331 is adhered with a sealing sheet 333, and the sealing sheet 333 is provided with a through hole 3331 corresponding to the opening 331 and a connection through hole 3332 corresponding to the connection screw hole 3311.

When assembling, the sealing sheet 333 is attached to the opening 331 on the top surface of the transmission case 33, the through hole 3331 of the sealing sheet 333 is aligned with the opening 331, and the coupling through-holes 3332 of the sealing plate 333 are aligned with the coupling screw holes 3311, the joint wall 411 of the front housing 41 of the external motor 40 is then attached to the sealing sheet 333 and the top surface of the transmission case 33, so that the coupling through-hole 412 of the front cover 41 is aligned with the coupling through-hole 3332 of the sealing sheet 333 and the coupling screw hole 3311 of the transmission case 33, in the process, the intermediate gear 44 in the front housing 41 is engaged with the transmission gear 332, and then is fastened to the engagement screw holes 3311 by bolts passing through the engagement through holes 412 and the engagement through holes 3332, this achieves the assembling relationship of the front end of the external motor 40 fixed to the top surface of the transmission case 33 by the front cover 41.

With reference to fig. 6 to 8, it is mentioned that the stationary motors 31 and 32 are assembled on the outer side of the transmission case 33, and then the front ends of the output shafts of the motors 31 and 32 extend into the transmission case 33, and are respectively provided with an output gear 311 and 321, which are arranged such that the output gear 311 and 321 and the transmission gear 332 are engaged with an initial gear 51 (as shown in fig. 7 and 8), so that the output of the motors 31 and 32 is transmitted to the initial gear 51 through the output gear 311 and 321, respectively, and the output of the external motor 40 is also transmitted to the initial gear 51 through the transmission of the output gear 43 and the intermediate gear 44.

The initial gear 51 belongs to the foremost gear of a transmission device 50 (as shown in fig. 7 and 8), and as mentioned above, the transmission device 50 is installed inside the transmission device box 33, and after each stage of transmission, drives a rope pulley 34 disposed below the set of motors 31 and 32 to rotate, so that the rope (steel rope or synthetic rope) wound around the rope pulley 34 can be controlled by power, and can make the action of releasing or retracting the rope (steel rope or synthetic rope) when necessary; since the transmission device 50 is not the focus of the improvement and development of the present invention, it is not necessary to describe the structure and operation thereof.

As mentioned above, the external motor 40 is an optional "third motor" that can be selectively assembled and disassembled, and the operations for selectively assembling the external motor 40 are shown in FIGS. 6-8 and the processes described above. To selectively remove the external motor 40 from the assembled state, the bolts locked in the joint through hole 412, the joint through hole 3332 and the joint screw holes 3311 are first removed, and the rear bracket 42 engaged with the rear end of the external motor 40 is disengaged from the support base 35, so that the external motor 40, the front cover 41 at the front end and the rear bracket 42 at the rear end can be lifted up and away from the winch 30, and during the process, the intermediate gear 44 in the front cover 41 and the transmission gear 332 are disengaged from the original engagement state, so that the external motor 40 (together with the front cover 41 at the front end and the rear bracket 42 at the rear end) can be lifted up and away from the winch 30.

After the external motor 40 (together with the front housing 41 at the front end and the rear support frame 42 at the rear end) is removed from the winch 30, since a small part of the gear body of the transmission gear 332 extends upwards out of the opening 331, a decoration cover 60 can be placed on the opening 331 to cover the opening 331 and the transmission gear 332, as shown in fig. 9 and 10, the body of the decoration cover 60 can be deliberately manufactured to be in a high state, and an advertisement pattern can be manufactured on the surface, and then the front side and the rear side of the bottom of the body extend outwards to form a joint wall body 61, and the joint wall body 61 is provided with joint through holes 62; when the cover 60 is placed on the opening 331, the engagement wall 61 of the cover 60 is attached to the sealing sheet 333 (since the sealing sheet 333 is not detached from the front housing 41), and then the screw bolts are inserted through the engagement holes 62, 3332 and then locked with the engagement screw holes 3311, so as to cover the opening 331 with the cover 60, and achieve the assembling and the advertising effects.

Thus, in a manufacturing facility, it is possible to assemble a complete winch 30 having three motors 31, 32, 40, and then a user (often a player of an off-road vehicle, a jeep, or a recreational vehicle) purchases the complete winch 30 mounted on the vehicle, and then the use of all three motors 31, 32, 40 can be selected to provide the highest torque to the transmission 50 to provide the maximum pulling force and the fastest pulling speed to the cable pulley 34, which is suitable for use in higher loads and more severe environments. Then, when the user evaluates that the highest torque is not needed recently, the user can choose to detach the external motor 40 automatically to save electricity and energy.

As can be seen from the above description, the present invention is mainly characterized in that an external motor (third motor) can be selectively assembled on a winch driven by a set of motors, so that a transmission device installed in a transmission device box of the winch is simultaneously subjected to power transmission of the three motors, thereby providing a larger pulling force and a faster pulling speed for a cable pulley of the winch, and providing a wider application range; the external motor (the third motor) can be removed when not needed, so that only two motors provide power, thereby saving electricity and energy.
