[0029] Referring to Figures 1-7 , in this embodiment, an in-motor electric winch is proposed, which includes a drum assembly 3, and both ends of the drum assembly 3 are installed on a support bracket 4; the support bracket 4 in this embodiment includes a first support plate 402, a second support plate 401 and a winch fixing seat 403, and the first support plate 402 and the second support plate 401 are fixed on the winch fixing seat 403. A rope arranging assembly 5 is provided at the top of the drum assembly 3, both ends of the rope arranging assembly 5 are fixed on the support bracket 4, and a rope arranging clutch 2 is connected between the rope arranging assembly 5 and the drum assembly 3; a rope pressing mechanism 8 is connected to the bottom of the support bracket 4, and the rope pressing mechanism 8 can press the wound rope tightly on the drum assembly 3; a manual brake assembly 7 is also connected to the drum assembly 3; an operating handle is detachably connected to the support bracket 4 and an operating box 10 is fixedly connected.

[0030] The reel assembly 3 includes a reel 304. One end of the reel 304 is fixedly connected to the rotating end of a speed reducer 306 and can rotate following the rotating end of the speed reducer 306. An emergency release output shaft 307 into which a manual hand crank can be inserted is provided at the end of the speed reducer 306. A driving motor 1 is provided at the other end of the reel 304. The driving motor 1 is an in-built permanent magnet explosion-proof motor. An electromagnetic brake 101, a motor encoder 102 and a temperature sensor are connected inside the in-built permanent magnet explosion-proof motor. A coupling 305 is provided inside the reel 304. The output end of the driving motor 1 is connected to the input end of the speed reducer 306 through the coupling 305. The speed reducer 306 is fixed on a first support plate 402, and the driving motor 1 is fixed on a second support plate 401. A transition connecting plate 302 is also fixedly connected to the side wall of the reel 304 on the side connected to the driving motor 1. A driving sprocket 301 coaxial with the reel 304 is connected to the transition connecting plate 302. A support bearing 303 is installed between the transition connecting plate 302 and the output shaft of the driving motor 1.

[0031] Operating principle of the reel assembly 3: Start the winch. The in-built permanent magnet explosion-proof motor outputs high-speed rotational energy, drives the shell of the speed reducer 306 to rotate through the coupling 305, and drives the reel 304 connected to the shell to rotate, reducing the high speed to a low speed and realizing the function of speed reduction and torque increase. An emergency release output shaft 307 is provided. Matched with it is a manual hand crank inserted into this shaft. When a fault occurs, insert the manual hand crank into the emergency release output shaft 307, rotate the hand crank, drive the reel 304 to rotate through the speed reduction and torque increase of the speed reducer 306, and realize manual lowering.

[0032] The rope arranging assembly 5 includes a first connecting plate 501 and a second connecting plate 507. The first connecting plate 501 and the second connecting plate 507 directly and parallely connect a transmission shaft 502 and a two-way lead screw 503. A sliding assembly 504 is slidably connected to the transmission shaft 502. The sliding assembly 504 is connected to the two-way lead screw 503. A small gear 508 is connected to the end of the transmission shaft 502, and a large gear 506 is connected to the end of the two-way lead screw 503. The rotation of the transmission shaft 502 drives the rotation of the two-way lead screw 503. A driven sprocket 505 cooperating with the driving sprocket 301 is rotatably connected to the transmission shaft 502.

[0033] The sliding assembly 504 includes a sliding frame 511. A rope pulley 510 is rotatably connected to the sliding frame 511. The rope pulley 510 can rotate following the transmission shaft 502 and slide on the transmission shaft 502. A pressing rope wheel 509 is also connected to the sliding frame 511. The pressing rope wheel 509 can press the wound rope onto the rope pulley 510. A threaded hole is provided on the sliding frame 511, and it can move horizontally following the rotation of the two-way lead screw 503.

[0034] Working principle: The driving sprocket 301 on the drum assembly 3 drives the chain to rotate the driven sprocket 505, driving the transmission shaft 502 and the rope pulley 510 to rotate. The winding rope is pressed against the rope pulley 510 by the pressing rope pulley 509. Since the linear velocity of the rope groove of the rope pulley 510 is greater than the linear velocity of the wire rope, the rope pulley 510 plays a role in dragging the winding rope to move, keeping the winding rope in a tensioned state all the time; the rotation of the transmission shaft 502 drives the small gear 508 to rotate, and the small gear 508 drives the large gear 506 to rotate the bidirectional lead screw 503. The guide pin in the bidirectional groove on the shaft of the bidirectional lead screw 503 drags the slider assembly to move left and right, thereby driving the winding rope to move left and right, achieving the effect of automatic rope laying.

[0035] The rope laying coupling 305 includes a clutch fixed seat 204, which is fixed on the second support plate 401. The clutch fixed seat 204 is vertically rotatably connected to the eccentric clutch shaft 203. The bottom of the eccentric clutch shaft 203 is connected to the clutch rotating plate 205, and the clutch rotating plate 205 is driven to rotate by the clutch handle 206; the top of the eccentric clutch shaft 203 is connected to the clutch wheel 202, and the clutch wheel 202 is installed on the transmission shaft 502 and can rotate and move axially along with the transmission shaft 502. One side of the eccentric clutch shaft 203 contacts the driven sprocket 505, and a bearing is installed between the driven sprocket 505 and the transmission shaft 502, and the driven sprocket 505 can rotate relative to the transmission shaft 502.

[0036] Working principle of the rope laying coupling 305: Figure 6 The middle rope laying clutch 2 is in a connected state, that is, the rotation of the driven sprocket 505 can drive the transmission shaft 502 to rotate, realizing the function of automatic rope laying. If the rope laying clutch 2 is to be in a separated state, as Figure 7 shown, pull the clutch handle 206 and rotate it by a certain degree to disengage the clutch wheel 202 from the driven sprocket 505. In this way, when the driven sprocket 505 rotates, it cannot drive the transmission shaft 502 to rotate, achieving separation.

[0037] Operating method of the whole machine:

[0038] Start the winch to make the driving motor 1 output high-speed rotation energy. Drive the reducer 306 to rotate through the coupling 305, reduce the high speed to a low speed, increase the torque, and drive the drum 304 to rotate, realizing the up and down movement of the heavy object. The driving sprocket 301 on the drum 304 drives the driven sprocket 505 on the rope laying assembly 5 to rotate through the chain, making the rope laying assembly 5 work and realizing the automatic rope laying of the winding rope. There is an emergency release output shaft 307, and correspondingly, an artificial hand crank is inserted into this shaft. When a fault occurs, insert the artificial hand crank into the emergency release output shaft 307 and rotate the hand crank to drive the drum 304 to rotate through the reducer 306, realizing manual lowering.

[0039] The winch can be operated remotely through the operation box 9. There are operation handles and emergency stop buttons on this box. Operating the handle on this box can lift and lower heavy objects with the steel wire rope. By adjusting the opening angle of the operating handle, stepless speed regulation can be achieved. In case of a malfunction, pressing the emergency stop button can achieve an emergency stop. Through the fixed control box, functions such as switching between carrying people and carrying goods, lifting and lowering the winch can also be realized.

[0040] Although the specific implementation manners of the utility model are described above in conjunction with the accompanying drawings, they do not limit the protection scope of the utility model. Based on the technical solutions of the utility model, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the utility model.
