Detailed Description

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1: the cable conveying device with protection function for electric power construction comprises a housing 1, a control panel is arranged at the rear part of the left side of the housing 1, two first support plates 101 and two first sliding blocks 103 are symmetrically distributed on the right side of the housing 1, two second sliding blocks 104 are symmetrically distributed on the left side of the housing 1, the first sliding blocks 103 are rotationally connected with first driving wheels 105, the second sliding blocks 104 are rotationally connected with second driving wheels 106, rotary belts 107 are respectively arranged between the first driving wheels 105 on the front side and the rear side and the corresponding second driving wheels 106, the rotary belts 107 on the front side and the rear side are matched for clamping cables, the first support plates 101 on the front side are provided with protection components 01, the protection components are used for protecting the cables when the cables encounter the inexhaustible obstruction, the protection components 01 comprise motors 108, the motor 108 is fixedly connected with the first supporting plate 101 at the front side, the lower spline of the output shaft of the motor 108 is connected with the driving wheel 109, a supporting spring 110 is arranged between the motor 108 and the driving wheel 109, the first driving wheel 105 at the front side is fixedly connected with the driven wheel 111, the lower side surface of the driving wheel 109 is provided with a convex block, the convex block is in an arc triangular block shape, the upper side surface of the driven wheel 111 is provided with a groove with the same shape as the convex block arranged at the lower side surface of the driving wheel 109, under the normal state, the driving wheel 109 is matched with the groove at the upper side surface of the driven wheel 111 through the convex block at the lower side surface of the driving wheel 109, the driven wheel 111 is driven to rotate, when the cable encounters obstruction, the convex block at the lower side surface of the driving wheel 109 is separated from the groove at the upper side surface of the driven wheel 111, the transmission between the driving wheel 109 and the driven wheel 111 is released, the driving wheel 109 is provided with a pressure sensor for detecting the elasticity of the supporting spring 110, the alarm value of the signal transmitted by the pressure sensor to the control panel is the value of the pressure sensor acted on by the supporting spring 110 after the driving wheel 109 and the driven wheel 111 are disengaged, the pressure sensor on the driving wheel 109 is electrically connected with the control panel, the first supporting plate 101 on the front side is provided with a turning assembly 02 for turning the first driving wheel 105, so that the cable between the two turning belts 107 and the blocking position is released, and the motor 108 is electrically connected with the control panel.

As shown in fig. 4, the turning assembly 02 includes a turning wheel 112, the turning wheel 112 is rotatably connected to the front first support plate 101, a torsion spring 113 is installed between the turning wheel 112 and the front first driving wheel 105, after the transmission between the driving wheel 109 and the driven wheel 111 is released, the torsion spring 113 is used to rotate the turning wheel 112, thereby releasing the cable between the two turning belts 107 and the blocking position, preventing the cable from being stretched for a long time to generate deformation, the connection between the turning wheel 112 and the corresponding first support plate 101 has damping, the torsion force of the torsion spring 113 is less than the damping between the turning wheel 112 and the corresponding first support plate 101, and when the front first driving wheel 105 starts to rotate, the turning wheel 112 does not rotate, thereby making the torsion spring 113 accumulate force, until the front first driving wheel 105 drives the turning wheel 112 to rotate through the torsion spring 113 after the accumulation of the torsion spring 113.

When the device is used for conveying cables, a user places the cables at the center position between the two rotating belts 107, then the user starts the motor 108 through the control panel, the output shaft of the motor 108 drives the driving wheel 109 to rotate, the driving wheel 109 drives the driven wheel 111 to synchronously rotate, the driven wheel 111 drives the first driving wheel 105 at the front side and the rotating belt 107 to synchronously rotate, the cables clamped by the two rotating belts 107 are conveyed to the right, and simultaneously the cables drive the rotating belt 107 at the rear side and the first driving wheel 105 at the rear side to synchronously rotate.

In the above process, because damping exists between the rotating wheel 112 and the corresponding first supporting plate 101, when the first driving wheel 105 starts to rotate, the torsion spring 113 starts to store force, and when the torsion spring 113 finishes storing force, the first driving wheel 105 at the front side drives the rotating wheel 112 to synchronously rotate through the torsion spring 113.

In the process of conveying the cable by the two rotary belts 107, when the cable encounters an obstruction, and the resistance to the movement of the cable increases, the resistance to the rightward movement of the cable increases, so that the friction force applied to the rotary belt 107 on the front side increases, the friction force is transmitted to the driven wheel 111 through the first driving wheel 105 on the front side, the rotation of the driven wheel 111 is prevented, the extrusion force between the driving wheel 109 and the driven wheel 111 increases, the driving wheel 109 starts to move upward, and the supporting spring 110 starts to compress, and in this process: when the capstan 109 is not disengaged from the capstan 111, the capstan 111 still follows the capstan 109 and the two rotary belts 107 still convey the cable to the right.

When the driving wheel 109 is separated from the driven wheel 111, the pressure sensor on the driving wheel 109 detects that the elastic force generated by the supporting spring 110 exceeds a set value, the pressure sensor sends a signal to the control panel, and the control panel turns off the motor 108 to stop the rotation of the driven wheel 111, so that cable stretching deformation caused by cable blocking force and the stretching force of the two rotating belts 107 is avoided, and cable sheath damage is caused.

In the above process, when the driving wheel 109 is out of engagement with the driven wheel 111, the torsion spring 113 loses resistance and starts to reset, and the first driving wheel 105 at the front side starts to rotate reversely under the driving of the torsion spring 113, so that the driving rotating belt 107 rotates reversely to convey the cable to the left, and the tensile force applied to the cable between the two rotating belts 107 and the blocking part is reduced, and the cable is prevented from being damaged due to stretching.

In the above process, when the control panel turns off the motor 108, the user checks the cable conveying path and removes the obstruction, and then repeats the above process to convey the cable again to the right.

In the process of conveying the cable, the control panel can detect the rotation speeds of the front first driving wheel 105 and the rear first driving wheel 105 through the two rotation speed sensors 208 at any time, when the clamping force of the two rotation belts 107 to the cable is insufficient and a slipping phenomenon occurs, the rightward movement speed of the cable is slower than that of the front rotation belt 107, but the rotation belts 107 on the rear side synchronously move along with the cable, namely, the rotation speeds of the front first driving wheel 105 and the rear first driving wheel 105 are inconsistent, at the moment, the two rotation speed sensors 208 detect the rotation speeds of the front first driving wheel 105 and the rear first driving wheel 105 are inconsistent, signals are transmitted to the control panel, then the control panel controls the telescopic ends of the electric push rods 210 to extend leftwards, the telescopic ends of the electric push rods 210 drive all the first racks 212 to move leftwards together through the transmission rods 211, the first racks 212 are meshed with the corresponding unidirectional gears 207 after moving leftwards for a certain distance, the corresponding unidirectional gears 207 rotate clockwise, the unidirectional gears 207 drive the corresponding rotation shafts 203 to rotate clockwise, the first support plates 101, the second support plates 102 and the third support plates 201 move oppositely, the rotation shafts 203 drive the two rotation shafts 101, the two rotation belts to clamp the cable, and the cable to stably rotate rightwards, and the cable is more stable.

In the above process, when the rotation shaft 203 rotates clockwise, the rotation shaft 203 drives the extrusion wheel 2181 to rotate, the extrusion wheel 2181 drives the transmission gear 218 to rotate under the extrusion action of the fifth spring 2182, the transmission gear 218 drives the second rack 219 to move upwards, the second rack 219 drives the detection rod 216 to move upwards through the fourth sliding block 215, but under the blocking action of the cable, the detection rod 216 cannot move upwards, so the second rack 219 cannot drive the fourth sliding block 215 to move upwards, the transmission gear 218 cannot rotate, and a reverse extrusion force is generated on the extrusion wheel 2181, so that the extrusion wheel 2181 moves backwards, compresses the adjacent fifth spring 2182, and the extrusion wheel 2181 and the adjacent transmission gear 218 lose fit.

When the rotation speeds detected by the two rotation speed sensors 208 are consistent, the control panel controls the telescopic end of the electric push rod 210 to drive the parts on the electric push rod to reset rightwards together, the unidirectional gear 207 does not transmit power in the process, namely the rotation shaft 203 does not rotate reversely, and the clamping force of the two rotation belts 107 on the cable is maintained.

Because the haulage rope is often used in consideration of the conveying cable, in order to solve the problem that the diameters of the haulage rope and the cable are inconsistent, the device is also designed with a reducing adaptation component 06 which can automatically adapt to the switching of different diameters of the haulage rope and the cable, and the specific operation principle is as follows: when the present apparatus is used to convey the traction rope, the clamping force between the two rotation belts 107 is the clamping force when clamping the traction rope, the detection rod 216 is closely attached to the traction rope, and the user needs to pull the pressing plate 206 backward after performing the clamping operation even if the transmission is no longer synchronized between the rotation shafts 203.

When the cable is pulled to be close to the left end of the device by the pulling rope, the cable can sequentially squeeze the adjacent detection rods 216 from left to right in the rightward moving process, and taking the detection rod 216 which is positioned at the leftmost side and is squeezed first in the rightward moving process as an example: the leftmost detection rod 216 is extruded by the cable to move downwards, the leftmost detection rod 216 drives the leftmost second rack 219 to move downwards through the leftmost fourth sliding block 215, the leftmost second rack 219 drives the leftmost transmission gear 218 to rotate anticlockwise, the leftmost transmission gear 218 rotates anticlockwise, the adjacent extrusion wheel 2181 is driven by the leftmost transmission gear 218 to rotate anticlockwise, the leftmost rotation shaft 203 is driven by the extrusion wheel 2181 to rotate, the leftmost rotation shaft 203 drives the two second support plates 102 to move outwards for a certain distance through threads, the pressure of the second support plates 102 and the corresponding extrusion springs to the second sliding blocks 104 is relieved, the extrusion force of the two second transmission wheels 106 to the traction ropes is relieved, the cable can enter between the rotation belts 107 more easily, excessive extrusion force on the cable after the cable is switched due to the fact that the traction ropes are thinner than the cable is avoided, and the problem that the cable surface is damaged is solved.

In the above process, the moving distance of the two second support plates 102 is positively correlated with the detected diameter change, so that the extrusion force of the two second driving wheels 106 received by the cable is similar to the extrusion force of the two second driving wheels 106 received by the traction rope before the detection rod 216 moves down, and therefore, the cable is directly adapted to the subsequent conveying process without being clamped again.

In this process, because the cables sequentially press the adjacent detecting rods 216 from left to right in the rightward moving process, when the leftmost detecting rod 216 is pressed, because the telescopic end of the electric push rod 210 is in a contracted state, when any transmission gear 218 drives the corresponding rotating shaft 203 to rotate, because the unidirectional gear 207 is disengaged from the first rack 212, that is, the other rotating shafts 203 cannot be rotated by pushing the transmission rod 211, only the leftmost rotating shaft 203 rotates, that is, the two third transmission wheels 2021 and the first transmission wheel 105 still press the adjacent rotating belt 107, and clamp the traction rope positioned on the right side of the cables, so that the right rotating belt 107 can continuously clamp the traction rope to move rightward.

After the cable passes through the detection rod 216 at the leftmost side, the cable can sequentially extrude the detection rod 216 at the right side from left to right in the rightward moving process of the cable, so that the first support plate 101 and the two third support plates 201 can sequentially adjust the clamping force according to the cable positions from left to right, and the cable and the traction rope are always in a clamping state in the switching process, namely, the phenomenon of slipping can not occur, the working flow of manually replacing the traction rope and the cable is replaced, the labor intensity of workers is reduced, the process of re-clamping and debugging the cable is omitted, and the reliability of the device is improved.

After the cable passes through the leftmost detection rod 216, the leftmost detection rod 216 does not move downwards, and then the two second support plates 102 also stop moving, and then in the process of passing through the leftmost second detection rod 216, the second support plates 102 limit the adjacent third support plates 201, so that the situation that the movement distance of the third support plates 201 is too large, and the two rotating belts 107 cannot convey cables to the right is avoided.

The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related arts are included in the scope of the present invention.
