Specific implementation manners

[0026] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0027] Example 1, referring to Figure 1 , this example provides a steel cable sheath fitting device, including a crawling component 1 and a fitting component 2. The crawling component 1 includes a front claw 101, a first connecting rod 102, a cam plate 103 and a first lead screw motor 104. The front claw 101 is rotatably connected to the first connecting rod 102, the first connecting rod 102 is rotatably connected to the cam plate 103, and the cam plate 103 is fixedly connected to the first lead screw motor 104; When the stepping motor 107 is started, the motor gear 108 also rotates accordingly. The motor gear 108 is in transmission connection with the main shaft gear 109, so it will also drive the main shaft gear 109 to rotate. When the main shaft gear 109 rotates, it will drive the main shaft 110 to rotate. The rotation of the main shaft 110 will then drive the first crank 111 to rotate. The first crank 111 and the second crank 113 are rotatably connected by the first bolt 112, so it will drive the second crank 113 to rotate, and then realize the rotation structure of the crank rocker. When the lead screw motor 104 is started, the cam plate 103 will slide on the sliding seat 105. When the cam plate 103 slides, it will drive the first connecting rod 102 to rotate, so as to realize the opening and closing degree of the front claw 101, and can adjust different opening and closing angles according to steel cables of different thicknesses.

[0028] The laminating assembly 2 includes a disc 201, a first gear 202, a film winding drum 203, a fixing block 204 and a double-rivet clamp 205. The disc 201 is fixedly connected to the first gear 202, the first gear 202 is fixedly connected to the film winding drum 203, the first gear 202 is fixedly connected to the fixing block 204, and the fixing block 204 is fixedly connected to the double-rivet clamp 205.

[0029] A roller 222 is fixedly connected to the double-rivet clamp 205. A number of ball bearings are provided on the roller 222, enabling rolling in the front, back, left and right directions. This can not only make the laminating assembly 2 move more smoothly on the steel cable, but also make the film winding drum 203 rotate more smoothly when laminating the film. Inside the clamp of the double-rivet clamp 205, a second spring 224 and a second ball bearing 225 are provided. There are grooves inside the clamp. When rotated by a certain angle, the second spring 224 has an outward tension, and the second ball bearing 225 will be ejected into the groove. When rotated by a certain angle again, the second spring 224 will receive an inward extrusion force, and then the second ball bearing 225 will also be squeezed to the inside. At this time, just pull it outwards to open the clamp.

[0030] The cam plate 103 is slidably connected to the sliding seat 105. The sliding seat 105 is fixedly connected to the upper frame plate 106. The upper frame plate 106 is fixedly connected to the stepping motor 107. The stepping motor 107 is fixedly connected to the motor gear 108. The motor gear 108 is in transmission connection with the main shaft gear 109. The main shaft gear 109 is fixedly connected to the main shaft 110. The main shaft 110 is rotatably connected to the first crank 111. The first crank 111 is rotatably connected to the second crank 113 through the first bolt 112.

[0031] When the stepping motor 107 is started, the motor gear 108 also rotates accordingly. The motor gear 108 is in transmission connection with the main shaft gear 109, so it will also drive the main shaft gear 109 to rotate. When the main shaft gear 109 rotates, it will drive the main shaft 110 to rotate. When the main shaft 110 rotates, it will drive the first crank 111 to rotate. The first crank 111 and the second crank 113 are rotatably connected through the first bolt 112, so it will drive the second crank 113 to rotate, thus realizing the rotational structure of the crank and rocker.

[0032] The upper frame plate 106 is fixedly connected to the sliding seat 105. The sliding seat 105 is fixedly connected to the lead screw motor 104. The lead screw motor 104 is fixedly connected to the coupling 114. The lead screw motor 104 is fixedly connected to the cam plate 103.

[0033] When the lead screw motor 104 starts, the cam plate 103 will slide on the slide block 105. When the cam plate 103 slides, it will drive the first connecting rod 102 to rotate, thereby realizing the opening and closing degree of the front claw 101, and the opening and closing angle can be adjusted according to steel cables of different thicknesses.

[0034] A friction plate 115 is fixedly connected to the surface of the front claw 101.

[0038] The above structure uses a double crank structure. When the motor 207 starts, the second gear 206 rotates, and then drives the first gear 202 to rotate. During the rotation of the first gear 202, since the film winding drum 203 and the double rivet clamp 205 face each other, no winding phenomenon will occur. The film on the film winding drum 203 passes through the balls on the roller 222, and faster film covering can be realized. While covering the film once, the fan 223 will blow hot air on the film covering surface to ensure that the film covering is tighter. After the motor 207 starts, the first thread 208 at its bottom also rotates accordingly, and then drives the third gear 209 to rotate. When the third gear 209 rotates, it will drive the gear teeth 211 at the bottom of the pin 210 to rotate. A first spring 213 and a first ball bearing 214 are provided at the top of the pin 210, and the position where it comes out is sufficient to catch the third gear 209 and rotate, which is only useful when the pin 210 moves downward. When the pin 210 is pulled upward, other objects below will not move, which means that the angle has been adjusted at this time and will not move anymore. The gear teeth 211 will drive the fourth gear 215 to rotate, then drive the second connecting rod 217 to rotate, then drive the third connecting rod 218 to rotate, then drive the fourth connecting rod 219 to rotate, and since the fifth connecting rod 220 is fixed, it will not rotate. The rotation of the other three connecting rods can adjust the angle of the fitting assembly 2.

[0039] A hole 212 is provided at the upper end of the pin 210. The first spring 213 is fixedly connected inside the hole 212, and both ends of the first spring 213 are fixedly connected to the first ball bearing 214.

[0040] The top of the pin 210 is provided with a first spring 213 and a first ball bearing 214. Its emerging position is sufficient to catch the third gear 209 and rotate, which is only useful when the pin 210 moves downward. When the pin 210 is pulled upward, other objects below will not move, which means the angle has been adjusted at this time and will not move anymore.

[0041] The gear tooth 211 is drivingly connected to a fourth gear 215. The fourth gear 215 is fixedly connected to a fixed rod 216. The fixed rod 216 is fixedly connected to a second connecting rod 217. The second connecting rod 217 is rotatably connected to a third connecting rod 218. The third connecting rod 218 is rotatably connected to a fourth connecting rod 219. The first connecting rod 102 is fixedly connected to a fifth connecting rod 220.

[0042] After the motor 207 is started, the first thread 208 at its bottom also rotates accordingly, and then drives the third gear 209 to rotate. When the third gear 209 rotates, it will drive the gear tooth 211 at the bottom of the pin 210 to rotate. The top of the pin 210 is provided with a first spring 213 and a first ball bearing 214. Its emerging position is sufficient to catch the third gear 209 and rotate, which is only useful when the pin 210 moves downward. When the pin 210 is pulled upward, other objects below will not move, which means the angle has been adjusted at this time and will not move anymore. The gear tooth 211 will drive the fourth gear 215 to rotate, then drive the second connecting rod 217 to rotate, then drive the third connecting rod 218 to rotate, and then drive the fourth connecting rod 219 to rotate. Since the fifth connecting rod 220 is fixed, it will not rotate. The rotation of the other three connecting rods can adjust the angle of the fitting assembly 2.

When rotated by a certain angle, the second spring 224 has an outward tension, and the second ball bearings 225 will be popped into the grooves. When rotated by a certain angle again, the second spring 224 will receive an inward extrusion force, and then the second ball bearings 225 will also be squeezed to the inside. At this time, just pull it outward to open the clamp.

[0047] Example 2, with reference to Figure 4 , Figure 5 and Figure 6 , the laminating assembly 2 includes a disc 201, a first gear 202, a film winding roller 203, a fixing block 204 and a double-rivet clamp 205.

A second spring 224 and a second ball bearing 225 are provided inside the clamp of the double-rivet clamp 205. There are grooves inside the clamp. When rotated by a certain angle, the second spring 224 has an outward tension, and the second ball bearing 225 will be popped into the groove. When rotated by a certain angle again, the second spring 224 will receive an inward squeezing force, and then the second ball bearing 225 will also be squeezed inside.

[0051] The above-mentioned structure uses a double-crank structure. When the motor 207 starts, the second gear 206 rotates, and then drives the first gear 202 to rotate. During the rotation of the first gear 202, since the film winding drum 203 and the double-rivet clamp 205 face each other, no winding phenomenon will occur. The film on the film winding drum 203 passes through the balls on the roller 222, enabling faster film covering. While covering the film once, the fan 223 will blow hot air on the film-covered surface to ensure that the film is covered more tightly. After the motor 207 starts, the first thread 208 at its bottom also rotates accordingly, and then drives the third gear 209 to rotate. When the third gear 209 rotates, it will drive the gear teeth 211 at the bottom of the pin 210 to rotate. The top of the pin 210 is provided with a first spring 213 and a first ball bearing 214. The position where it comes out is sufficient to grasp the third gear 209 and rotate, which is only useful when the pin 210 moves downward. When the pin 210 is pulled upward, other objects below will not move, which means that the angle has been adjusted at this time and will not move anymore. The gear teeth 211 will drive the fourth gear 215 to rotate, then drive the second connecting rod 217 to rotate, then drive the third connecting rod 218 to rotate, and then drive the fourth connecting rod 219 to rotate. Since the fifth connecting rod 220 is fixed, it will not rotate. The rotation of the other three connecting rods can adjust the angle of the fitting component 2.

[0052] A hole 212 is provided at the upper end of the pin 210. The first spring 213 is fixedly connected inside the hole 212, and both ends of the first spring 213 are fixedly connected to the first ball bearing 214.

[0067] The disk 201 can be opened, and a handle 221 is fixedly connected to the disk 201 .

[0068] It can ensure that the device is successfully inserted into the steel cable.

[0069] The double rivet clamp 205 is fixedly connected to the roller 222 , the double rivet clamp 205 is fixedly connected to the fixing block 204 , the fixing block 204 is fixedly connected to the fan 223 , a second spring 224 is arranged inside the double rivet clamp 205 , and the second spring 224 is fixedly connected to the second ball bearings 225 on both sides.

[0070] A second spring 224 and a second ball bearing 225 are arranged inside the double rivet clamp 205, and a groove is arranged inside the clamp. When the clamp is rotated to a certain angle, the second spring 224 has outward tension, and the second ball bearing 225 will be bounced into the groove. When the clamp is rotated to a certain angle again, the second spring 224 will be subjected to an inward squeezing force, and then the second ball bearing 225 will also be squeezed to the inside. At this time, the clamp can be opened by simply pulling it outward.

[0071] Working principle: When the stepper motor 107 is started, the motor gear 108 also rotates accordingly. The motor gear 108 is connected to the main shaft gear 109 by transmission, so it will also drive the main shaft gear 109 to rotate. When the main shaft gear 109 rotates, it will drive the main shaft 110 to rotate. The rotation of the main shaft 110 will then drive the first crank 111 to rotate. The first crank 111 is connected to the second crank 113 by the first bolt 112, so it will drive the second crank 113 to rotate, and then realize the rotation structure of the crank rocker. When the screw motor 104 is started, the cam plate 103 will slide on the slide 105. When the cam plate 103 slides, it will drive the first connecting rod 102 to rotate, thereby realizing the opening and closing degree of the front claw 101, and can adjust different opening and closing angles according to steel cables of different thicknesses.

[0072] The swivel head structure uses a double crank structure. When the motor 207 starts, the second gear 206 rotates, and then drives the first gear 202 to rotate. During the rotation of the first gear 202, since the film winding drum 203 and the double rivet clamp 205 face each other, no winding phenomenon will occur. The film on the film winding drum 203 passes through the ball on the roller 222, enabling faster film covering. While covering the film once, the fan 223 will blow hot air on the film-covered surface to ensure that the film is covered more tightly. After the motor 207 starts, the first thread 208 at its bottom also rotates accordingly, and then drives the third gear 209 to rotate. When the third gear 209 rotates, it will drive the gear teeth 211 at the bottom of the pin 210 to rotate. The top of the pin 210 is provided with a first spring 213 and a first ball bearing 214. The position where it comes out is sufficient to grasp the third gear 209 and rotate, which is only useful when the pin 210 moves downward. When the pin 210 is pulled upward, other objects below will not move, which means that the angle at this time has been adjusted and will not move anymore. The gear teeth 211 will drive the fourth gear 215 to rotate, then drive the second connecting rod 217 to rotate, then drive the third connecting rod 218 to rotate, and then drive the fourth connecting rod 219 to rotate. Since the fifth connecting rod 220 is fixed, it will not rotate. The rotation of the other three connecting rods can adjust the angle of the fitting component 2.
