[0032] A transmission mechanism 4 is installed inside the connecting shell 1. The transmission mechanism 4 includes a rotating shaft 41 and a positioning disk 43. The positioning disk 43 is installed on the inside of the connecting shell 1. A transmission wheel 44 is installed at one end of the positioning disk 43. The control motor 13 can drive the transmission wheel 44 to rotate. A threaded shaft 45 is movably provided inside the positioning disk 43. The threaded shaft 45 is movably sleeved on one end of the transmission wheel 44 and can move axially. The rotating shaft 41 is installed on one side of the threaded shaft 45. The rotating shaft 41 is wound with a transmission cable 42. When the electric hoist is needed, it can play the role of retracting and releasing the transmission cable 42 under the action of the transmission mechanism 4, and can evenly lay the transmission cable 42 on the rotating shaft 41, which can ensure the stability during the transmission process, reduce the shaking and bumping of the goods caused by the transmission cable 42, and can also reduce the wear between the transmission cables 42. In the process of winding and transmitting, the rotating shaft 41 can move axially inside the dust collecting tube 2 to clean the debris and dust. At the same time, under the action of the limit frame 3, the stability of the movement of the transmission cable 42 can be further maintained.

[0033] like Figure 7 As shown, in order to reduce the dust and debris from entering the connection shell 1, the position of the dust collecting pipe 2 corresponds to the rotating shaft 41, and the rotating shaft 41 can move axially inside the dust collecting pipe 2. A pair of connecting end blocks 23 are installed on the surface of the dust collecting pipe 2. The connecting end blocks 23 are clamped on the connecting end cover 11. The dust collecting pipe 2 can be installed and limited by the connecting end blocks 23. A positioning ring frame 14 is installed on the inner wall of the connecting end cover 11. The positioning ring frame 14 can also play an auxiliary support role. The dust collecting pipe 2 is installed inside the positioning ring frame 14;

[0034] A plurality of buffer shafts 24 are installed on the inner wall of the dust collecting tube 2. The buffer shafts 24 are arranged in a uniform array on the inner wall of the dust collecting tube 2. Compression pads 26 are installed at both ends of the buffer shafts 24. When the rotating shaft 41 enters the interior of the dust collecting tube 2, the surface of the rotating shaft 41 can be squeezed under the action of the compression pads 26, and the dust can be rubbed into thin strips or clumps, which are convenient for being stuck between the adsorption shafts 25, so as to facilitate subsequent unified collection and processing.

[0035] like Figure 8 As shown, in order to reduce the flying of dust inside the connection housing 1 and shorten the service life of the device, a plurality of adsorption shafts 25 are installed between the buffer shafts 24. The adsorption shafts 25 are arc-shaped and are evenly arranged in an array between the buffer shafts 24. An elastic shaft 251 is arranged between the buffer shafts 24. The elastic shaft 251 is clamped on the adsorption shaft 25 arranged vertically therewith.

[0036] A reset ring 21 is installed at the rear end of the dust collecting tube 2, and a blocking plate 22 is installed inside the reset ring 21. One end of the elastic shaft 251 can be stuck on the inner wall of the reset ring 21, and the blocking plate 22 can be against the axially movable rotating shaft 41, so that the reset ring 21 pulls the elastic shaft 251 to move, and the adsorption shaft 25 can be moved under the drive of the elastic shaft 251, so that dust and the like are stuck in the gap, which is convenient for subsequent cleaning.

[0037] like Figure 2 As shown, in order to reduce the surface damage of the transmission cable 42, a pair of straight grooves are opened at the bottom of the limit frame 3, and a pair of limit slides 31 are movably provided between the straight grooves. The spacing of the limit slides 31 can be adjusted and maintained to adapt to transmission cables 42 of different sizes. The limit slides 31 and the straight grooves are vertically staggered. Positioning balls 32 are installed at both ends of the bottom of the limit slide 31, and a rectangular frame 33 is installed between the positioning balls 32. A pair of sliding shafts 34 are provided between the rectangular frames 33. The sliding shafts 34 are located on both sides of the transmission cable 42. The sliding shafts 34 can fit on both ends of the transmission cable 42 to play a role in auxiliary positioning.

[0038] like Figure 3 As shown, in order to reduce the situation where debris and dirt enter the interior of the connecting shell 1, a transmission wheel 35 is rotatably provided on the sliding shaft 34. The transmission wheel 35 can rotate under the action of friction. A plurality of rubber sheets are installed on the side wall of the transmission wheel 35 for cleaning the transmission cable 42. The rubber sheets can quickly clean the surface of the transmission cable 42 to reduce the residual debris and dirt and keep the surface of the transmission cable 42 clean. A pair of reset shafts 341 are installed between the sliding shafts 34 for pressing the transmission wheel 35 against the surface of the transmission cable 42. The reset shaft 341 can make the position of the transmission wheel 35 adaptive and fit on the surface of the transmission cable 42 under the action of elasticity.

[0039] like Figure 5 As shown, a fixing ring is installed on the surface of the rotating shaft 41, and a welding end block is connected to the fixing ring, one end of the transmission cable 42 is clamped on the welding end block, and the transmission cable 42 is evenly wound on the rotating shaft 41. A plurality of telescopic rods 431 are installed on the positioning plate 43, and a ring groove is provided on the side of the fixing ring close to the telescopic rod 431, and one end of the telescopic rod 431 is movably clamped inside the ring groove. The control motor 13 is operated to drive the transmission wheel 44 and the threaded shaft 45 to move, thereby promoting the axial movement of the rotating shaft 41 on one side during the circular motion, and the transmission cable 42 can be evenly retracted and released to ensure the stability of the equipment operation.

[0040] like Figure 6As shown, in order to reduce the dust residue on the surface of the transmission cable 42, a plurality of hollow grooves are opened inside the rotating shaft 41, a movable ring is rotatably provided on the positioning plate 43, and a plurality of movable shafts 47 are installed on the movable ring, and the movable shafts 47 are arranged on the movable ring in an array of two by two, and a piston rod 48 is installed at one end of a pair of movable shafts 47, and the piston rod 48 is movably inserted inside the hollow groove, a plurality of arc grooves 411 are opened on the surface of the rotating shaft 41, and an elastic sieve plate is installed inside the arc groove 411, and a clamping ring 4 is installed at one end of the rotating shaft 41. 6. A plurality of one-way exhaust grooves are provided on the clamping ring 46, and the one-way exhaust grooves are connected with the hollow groove. With the axial movement of the rotating shaft 41, under the action of the piston rod 48 and in cooperation with the one-way exhaust grooves, negative pressure can be formed on the outside of the arc groove 411, so that part of the dust and debris adhered to and entangled on the surface of the transmission cable 42 can be adsorbed onto the elastic sieve plate on the top of the arc groove 411, and can be transported to the inside of the dust collecting pipe 2, so as to reduce the situation where debris and garbage remain on the surface of the transmission cable 42 during the cargo handling process.

[0041] like Figure 6 As shown, a grid pad 481 is installed at one end of the piston rod 48. The cross-section of the grid pad 481 is "L"-shaped. The grid pad 481 is squeezed between the elastic screen plate during transmission. The grid pad 481 can rub against the elastic piston plate during transmission, and the dust and debris stuck on the surface of the elastic piston plate will be shaken off into the dust collecting tube 2, which is convenient for subsequent cleaning and maintenance.

[0042] Working principle: First, when the electric hoist is needed, it can play the role of retracting and releasing the transmission cable 42 under the action of the transmission mechanism 4, and can evenly lay the transmission cable 42 on the rotating shaft 41, which can ensure the stability during the transmission process, reduce the shaking and bumping of the goods caused by the transmission cable 42, and can also reduce the wear between the transmission cables 42. In the process of winding and transmitting, the rotating shaft 41 can move axially inside the dust collecting tube 2 to clean up the debris and dust. At the same time, under the action of the limit frame 3, the stability of the movement of the transmission cable 42 can be further maintained. When the transmission cable 42 is unwinding, the control motor 13 can drive the threaded shaft 45 to rotate, pushing the rotating shaft 41 to move toward one side of the dust collecting pipe 2, so as to facilitate the cleaning of dust and dirt adhered to the surface of the rotating shaft 41. In addition, with the axial movement of the rotating shaft 41, with the cooperation of the piston rod 48, part of the dust and debris adhered to and entangled on the surface of the transmission cable 42 can be adsorbed onto the elastic screen plate at the top of the arc groove 411, and can be transported to the inside of the dust collecting pipe 2, so as to reduce the situation where debris and garbage remain on the surface of the transmission cable 42 during the cargo handling process.

[0043] Then, during the process of releasing the line from the rotating shaft 41, one end of the rotating shaft 41 can be abutted against the blocking plate 22, so that the pulling reset ring 21 can be moved, thereby cooperating with the elastic shaft 251 to pull the adsorption shaft 25 to move, so that the dust adhering to the surface of the rotating shaft 41 can be cleaned and recovered, which is convenient for subsequent unified treatment. After the transportation is completed, the control motor 13 can be turned over, thereby driving the rotating shaft 41 to rotate, so that the transmission cable 42 can be recovered, and when the threaded shaft 45 drives the rotating shaft 41 to move axially, the transmission cable 42 can be evenly laid on the surface of the rotating shaft 41, which can reduce the disorder when the transmission cable 42 is recovered and wound, and can reduce the wear during the winding process and the damage during the transmission process.

[0044] Finally, during the cable transmission process, the surface of the transmission cable 42 can be stuck between the transmission wheels 35, and the rubber sheet on the surface of the transmission wheel 35 can be pressed against the surface of the transmission cable 42 under the action of the reset shaft 341, thereby reducing the possibility of large particles of debris or foreign objects such as iron wire being stuck on the cable surface, reducing the wear of the transmission cable 42 after winding, and extending the maintenance cycle of the equipment.
