In order to facilitate the positioning of the cables on the first roller 11 and the second roller 13, two positioning discs 28 are coaxially and alternately arranged on the first roller 11 and the second roller 13.
The specific working process of the invention is as follows: when the device is used, the cable drum 2 uniformly wound with the cable is detachably mounted on a first support of the trolley 1, the cable drum 2 wound with the cable is a purchased finished product, the tension spring 12 is in a natural contraction state in an initial state, the pressure spring 14 is in a natural expansion state, the first roller 11 is at the lowest position, the second roller 13 is at the highest position, the pneumatic cylinder 15 is filled with gas, the extending end of the pneumatic telescopic rod 16 is in a retraction state, the left end of the labor-saving lever 17 is lower than the right end, therefore, the labor-saving lever 17 does not extrude the vertical rod 18, the first belt 5 is not pressed by the pressing wheel 6, the motor at the moment continuously rotates and cannot drive the cable drum 2 to rotate, the height of the L-shaped rod 7 is adjusted to enable the device to adapt to the height of the cable support, the head of the cable on the cable drum 2 is sequentially wound on the winding wheel 9 for at least one circle clockwise from the lower part of the first roller 11 and the upper part of the second roller 13, and then penetrates through the fixed pulley 23 and finally penetrates out of the positioning pipe 8 And the cable head is fixed on the cable holder.
The trolley 1 is moved rightwards at the moment, the trolley 1 moves to enable the friction wheel 10 in contact with the ground to rotate clockwise, the rotation of the friction wheel 10 drives the winding wheel 9 to rotate clockwise through the third belt wheel 21 and the fourth belt wheel 22, the cable wound on the winding wheel 9 is tightened at the moment, the cable on the cable winding drum 2 cannot be paid off autonomously due to large mass, when the cable is tightened by the winding wheel 9, the cable is stretched, the first roller 11 moves upwards when the cable is stretched, the second roller 13 moves downwards, in the process, the tension spring 12 is stretched and enables the tension spring to have a rebounding trend and elastic potential energy, the pressure spring 14 is compressed and enables the tension spring to have a rebounding trend and elastic potential energy, along with the continuous upward movement of the first roller 11, the piston cylinder of the pneumatic cylinder 15 extrudes gas in the pneumatic telescopic rod 16, and the extending end of the pneumatic telescopic rod 16 extends out, and the right end part of the labor-saving lever 17 is extruded, so that the right end of the labor-saving lever 17 moves downwards, meanwhile, the left end of the labor-saving lever 17 moves upwards and extrudes the vertical rod 18, the vertical rod 18 moves upwards to enable the pressing wheel 6 to press the first belt 5, so that the first belt 5 is tensioned, the cable drum 2 is driven by the motor to rotate for paying off, and the cable drum 2 rotates under the driving of the motor to have rotation inertia.
After the cable is released, the cable is loosened, the first roller 11 is reset downwards under the reset action of the tension spring 12 and the pressure spring 14, the second roller 13 is reset upwards, the first roller 11 moves downwards, so that the gas in the pneumatic telescopic rod 16 in the pneumatic cylinder 15 retracts into the pneumatic cylinder 15, and the right end of the labor-saving lever 17 is not pressed any more, the tension wheel is not pressed the first belt 5 any more, at the moment, the motor does not drive the cable drum 2 to pay off any more under the action of the tension wheel, when the cable between the first roller 11 and the second roller 13 is tightened again along with the continuous rotation of the winding wheel 9, the first roller 11 moves upwards again, the pneumatic cylinder 15 drives the labor-saving lever 17 again to extrude the pressing wheel 6, so that the motor drives the cable drum 2 again to realize cable paying-off, and the motor drives the cable drum 2 to pay off intermittently in the process, so that the intermittent matching continuously rotates the winding wheel 9 to tighten the cable.
The significant benefits of the present device:
1. in the actual cable laying process, the trolley 1 is continuously pulled to move manually, the winding wheel 9 driven by the friction wheel 10 continuously rotates in the process, the forward moving distance of the trolley 1 is the length of the cable which is conveyed upwards by the winding wheel 9, the pulling force on the cable in the cable conveying process is effectively reduced, meanwhile, a telescopic allowance exists between the first roller 11 and the second roller 13 for the cable, the telescopic allowance is a driving force for driving the cable drum 2 to rotate intermittently, when the cable between the first roller 11 and the second roller 13 is pulled to a certain degree, the pneumatic telescopic rod 16 extrudes the labor-saving lever 17 to realize that the pinch roller 6 extrudes the first belt 5, so that the first belt 5 is pressed tightly to drive the cable drum 2 to rotate to release the cable, and the process can effectively reduce the strain of the cable drum 2 on the cable when the cable is released.
2, when the cable is wound on the winding wheel 9, both ends of the cable need a pressing force to realize the function of transmitting the cable by the winding wheel 9, the pressing force with a smaller fluctuation range is provided for the winding of the end part of the cable on the winding wheel 9 in the compression and reset processes by the pressure spring 14 and the second roller 13, so that the cable can be pressed on the winding wheel 9, because the motor drives the cable drum 2 to be inching-driven, the cable drum has a rotation inertia every time the cable is paid off, the inertia realizes the loosening of the cable, the reciprocating motion of the first roller 11 and the tension spring 12 realizes the supporting of the loosened cable, the fluctuation range of the reciprocating motion of the rollers is larger than that of the reciprocating motion of the second roller 13, but because the controlled ends of the first roller 11 and the second roller 13 are different, the difference of the two groups of fluctuation roller ranges has little mutual influence effect, meanwhile, the cable drum 2 is electrically driven by the motor to pay off by utilizing the fluctuation range of the up-and-down reciprocating motion of the first rolling shaft 11, the cable on the winding wheel 9 is tightly pressed by the two groups of rolling shafts, and the point control driving of the motor to the cable drum 2 is realized, so that the cable drum 2 is driven to pay off by point according to the stock of the cable on the cable drum 2 in the process that the small trolley 1 continuously advances.
3. This device only removes through manual drive small handcart 1 and can the laying of efficient completion cable, need not to cooperate special unwrapping wire personnel again, also can not cause the strain of cable in laying process simultaneously, only uses some pure mechanical structure to realize the efficient unwrapping wire effect simultaneously, and the production of this device is simple and low in cost, makes things convenient for a large amount of popularization.
The cable end pulling device is novel in concept, ingenious in structure and strong in practicability, and effectively solves the problems that the existing subway cable erection process is low in efficiency and complicated in operation, and the cable end is directly pulled to drive the cable drum to rotate, so that the cable is easily damaged.
