Description
Technical Field
The utility model relates to a tensioner.
Background
The tensioner is often used for receiving and releasing lines, the received and released lines are all wound on a wire coil, and when the lines on the wire coil are about to be released, a tail rope on the wire coil needs to be connected to a new wire coil so as to ensure that the receiving and releasing lines can be continuously carried out. At present, when a wire coil of a tensioner is replaced, the tensioner is stopped firstly, then a tail rope is temporarily tensioned and stressed by manpower or a wire clamping device, after the tail rope is tensioned, the tail frame force can be closed, the wire coil replacing operation is started, after the wire coil is replaced, the tail frame force is loaded to be more than 5MPa firstly, and then the tensioned tail rope can be loosened, so that safety accidents are avoided; when relying on the taut tail rope of manpower, it is taut simultaneously to need two people or three people usually, whole trade line dish in-process, the personnel of taut tail rope can not have any lax, need to hold the tail rope all the time, however, the condition of the taut tail rope of manpower is only applicable to the less prerequisite of tail rope tension, under the great prerequisite of tail rope tension or the comparatively moist prerequisite of application environment, can only directly use the fixing-line device anchor line behind the taut tail rope of manpower, it is thus clear that, the taut mode of above-mentioned two kinds of tail ropes is all from the manpower, lead to still to coil inefficiency, and factor of safety when still coiling is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a coil of wire trades that efficient and factor of safety is high when trading the coil of wire tensioner.
The utility model relates to a tensioner, which comprises a tail frame, wherein a tail rope clamping device is arranged on the tail frame; the tail rope clamping device comprises a tail rope clamping oil cylinder, the tail rope clamping oil cylinder is connected with a tail frame pump of the tensioner through an oil pipe, and a three-position four-way reversing valve is arranged on the oil pipe which is connected with the tail frame pump of the tensioner through the tail rope clamping oil cylinder.
A tensioner, when needs trade drum, control tribit cross-over valve, make its P-B and T-A communicate with each other to promote the tail rope and press from both sides tight hydro-cylinder, make the tail rope press from both sides tight hydro-cylinder and press from both sides tight tail rope, after pressing from both sides tight tail rope, make tribit cross-over valve change to the meso position again, tail rope presss from both sides tight hydro-cylinder mouth B and the A auto-lock oil circuit of hydro-cylinder this moment, can unload tail frame power to 0 afterwards, can trade the line reel operation, and trade the line reel and accomplish the back, load tail frame power to 5MPｃA-12MPｃA earlier, control tribit cross-over valve and change to P-A and T-B and communicate with each other afterwards, thereby reverse promotion tail rope presss from both sides tight hydro-cylinder, make it loosen the tail rope, can begin to receive and release the. When the wire coil is replaced, the tail rope is tightened by the mutual cooperation of the tail frame pump, the three-position four-way reversing valve and the tail rope clamping oil cylinder, so that the tail rope can be automatically clamped and loosened, the tail rope is automatically clamped and loosened, the manual operation is avoided, the working efficiency of the wire coil replacement is improved, the structure is simple, and time and labor are saved; and because the manual operation is avoided, the occurrence of accidents is greatly reduced, and the safety factor is high.

Detailed Description
A tensioner, as shown in fig. 1 to 5, comprises a tail stock 1, wherein a tail rope clamping device 2 is arranged on the tail stock 1; the tail rope clamping device 2 comprises a tail rope clamping oil cylinder 3, the tail rope clamping oil cylinder 3 is connected with a tail frame pump 13 of the tensioner 5 through an oil pipe 4, and a three-position four-way reversing valve 6 is arranged on the oil pipe 4, which is connected with the tail frame pump 13 of the tensioner 5, of the tail rope clamping oil cylinder 3.
The tail rope clamping device 2 is arranged on the tail frame supporting frame 7. Because the tensioner 5 mainly drags the steel wire rope by means of friction force through the double winding drums to drive the rope to realize tension, the tensioner 5 generally has 5-7 wire slots, and the tension borne by the rope is reduced in sequence from the first wire slot at the wire outlet to the wire slot at the position of the tail frame supporting frame 7, therefore, in order to improve the safety performance of the tail rope clamping device 2 in working, the tail rope clamping device 2 is specially installed on the tail frame supporting frame 7, which corresponds to the last wire slot of the tensioner 5, therefore, the tension borne by the tail rope can be smaller, and meanwhile, a tail frame wire guide wheel is arranged behind the tail frame supporting frame 7, so that the moving distance of the tail rope clamping oil cylinder 3 in the tail rope clamping device 2 can be shortened.
The tail rope tensioning device is characterized by further comprising a loading protection device, the loading protection device comprises an amplifier and a travel switch 8, the amplifier is arranged in a tensioning machine take-up and pay-off control handle, the travel switch 8 is arranged on the bottom surface of the tail rope clamping device 2, a clamping plate 9 is connected to the end portion of a telescopic shaft of the tail rope clamping oil cylinder 3 in the tail rope clamping device 2, a pressing rod 10 is arranged at the bottom of the clamping plate 9, and the pressing rod 10 moves back and forth along with the clamping plate 9 to extrude the travel switch 8 or separate from the travel switch 8. When a tail rope needs to be clamped, the tail rope clamping oil cylinder 3 drives the clamping plate 9 to extend out under the action of the tail frame pump 13 so as to clamp the tail rope, meanwhile, the pressure rod 10 on the clamping plate 9 is separated from the travel switch 8, the travel switch 8 is powered off, so that the amplifier is powered off, the control handle for winding and unwinding the wire of the tensioner cannot rotate, and safety accidents caused by the rotation of the control handle for winding and unwinding the wire of the tensioner in the operation process of wire changing discs are effectively prevented; after the wire reel changing operation is finished, the tail rope clamping oil cylinder 3 drives the clamping plate 9 to retract under the action of the tail frame pump 13 so as to loosen the tail rope, and meanwhile, along with the continuous backward movement of the clamping plate 9, the pressing rod 10 on the clamping plate 9 extrudes the travel switch 8, so that the travel switch 8 is electrified, the amplifier is electrified, and the normal rotation of the control handle of the take-up and pay-off wire of the tensioner is ensured to pull the rope.
A fixed clamping plate 13 is arranged in front of the clamping plate 9, the distance between the clamping plate 9 and the fixed clamping plate 11 is the pushing distance of the clamping plate 9, and the maximum pushing distance of the clamping plate 9 is 138 mm-145 mm, such as 138mm, 139mm, 140mm, 141mm, 142mm, 143mm, 144mm or 145mm, preferably 140 mm. The maximum stroke of the tail rope clamping oil cylinder 3 is larger than the distance between the clamping plate 9 and the clamping plate 11, so that the tail rope clamping oil cylinder 3 is protected from being impacted on the premise of reserving stroke allowance, and the service life of the tail rope clamping oil cylinder is prolonged.
The distance between the fixed clamping plate 11 and the clamping plate 9 is 18 mm-22 mm larger than the distance between the two wire guide wheels 12 on the tension machine, such as 18mm, 19mm, 20mm, 21mm or 22mm, and preferably 20 mm.
The clamping plate 9 or the fixed clamping plate 11 and the adjacent guide wheel 12 are spaced apart by 8 mm-12 mm, such as 8mm, 9mm, 10mm, 11mm or 12mm, preferably 10mm, and the spacing is set such that the rope does not contact and wear when passing through.
