Abstract
The utility model discloses a steel wire rope fixed device, and relates to a hoisting device. The utility model aims to provide a steel wire rope fixed device on which the steel were rope can not be twisted. The utility model has the technical proposal with the key points as follows: the steel wire rope fixed device comprises a turn buckle, a connecting shaft, upper and lower fixed shafts and a steel wire rope lantern ring; a rotating mechanism is arranged between the connecting shaft and the fixed shafts; a screwed hole at the upper port of the sleeve of the rotating mechanism is matched with external threads at the lower end of the upper fixed shaft; the upper part of the upper fixed shaft is arranged in a grove at the lower part of the connecting shaft and is connected with the connecting shaft through a pin shaft; external threads at the upper end of the lower fixed shaft are matched with a nut in the sleeve; a bearing on the step cylindrical face under the thread section of the lower fixed shaft is arranged between the nut and the lower end face of the sleeve; the lower part of the lower fixed shaft is connected with a connecting plate outside the sleeve through another pin shaft; and a screwed hole is formed between the screwed hole of the nut and the thread surface at the upper end of the lower fixed shaft and is matched with a terminal strand. The utility model is used for cranes.
Description
Technical field:
The utility model relates to a kind of weight-lifting equipment, particularly a kind of wire rope fixing device.
Background technology:
Existing wire rope fixing device is made up of turnbuckle, adapter shaft and the steel rope collar, and this anchor fitting is worked as steel rope in the winding process of reel, and reversing of steel rope can influence its service life.
Summary of the invention:
The purpose of this utility model provides the wire rope fixing device that a kind of steel rope does not reverse.The technical solution of the utility model is, wire rope fixing device, comprise turnbuckle, adapter shaft, the anchor shaft and the steel rope collar, it is characterized in that: between adapter shaft and anchor shaft, be provided with rotating mechanism, the tapped bore of the sleeve upper port of this rotating mechanism and last anchor shaft lower end outside thread match, top of anchor shaft places the groove of adapter shaft bottom to be connected with adapter shaft by bearing pin on this, the outside thread of following anchor shaft upper end and the nut in the sleeve match, bearing on the step cylinder below the following anchor shaft thread segment places between above-mentioned nut and the sleeve lower surface, this is connected by the outer connecting panel of bearing pin and sleeve the bottom of anchor shaft down, is provided with tapped bore and jackscrew matches between the tapped bore of nut and the thread surface on the following anchor shaft.It is relative with bearing that sleeve wall is provided with lubricating cup.The utility model has the advantage that steel rope does not reverse compared with the prior art.
Description of drawings:
Accompanying drawing is the structural representation of the utility model wire rope fixing device.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, in order to solve the defective that existing wire rope fixing device can not avoid steel rope to reverse, between adapter shaft 2 and following anchor shaft 9, be provided with rotating mechanism, this rotating mechanism has a sleeve 6, the upper port of sleeve is that the external screw thread of tapped bore and last anchor shaft 3 lower ends matches, the external screw thread of anchor shaft upper end and the nut 7 in the sleeve match, bearing 8 on the stepped cylinder below following anchor shaft 9 thread segments places between nut 7 and the sleeve lower surface, on the screw thread hole wall of sleeve, be provided with radial screw bore and jackscrew 4 matches, on the lower cartridge hole wall relative, be provided with priming cup 8 with bearing.The lower end of following anchor shaft 9 is connected with connecting panel 10 by bearing pin, and the connecting panel lower end is provided with the steel rope collar 11.Between nut and anchor shaft, there are tapped bore and jackscrew to match, can prevent that nut and anchor shaft are loosening.
Anti-steel rope of the present utility model reverses principle of work and is, wire rope fixing device is in the lifting process, because what steel rope produced when twining on reel reverses, driving anchor shaft 9 reverses, owing to be provided with bearing, this at present anchor shaft 9 and sleeve, go up anchor shaft 3, adapter shaft 2 and turnbuckle 1 and do not follow rotation at the sleeve intort, thereby the steel rope of this wire rope fixing device can not produce and reverses its longer service life.
Claims (2)
1, wire rope fixing device, comprise turnbuckle, adapter shaft, the anchor shaft and the steel rope collar, it is characterized in that: between adapter shaft and anchor shaft, be provided with rotating mechanism, the tapped bore of the sleeve upper port of this rotating mechanism and last anchor shaft lower end outside thread match, top of anchor shaft places the groove of adapter shaft bottom to be connected with adapter shaft by bearing pin on this, the outside thread of following anchor shaft upper end and the nut in the sleeve match, bearing on the step cylinder below the following anchor shaft thread segment places between above-mentioned nut and the sleeve lower surface, this is connected by the outer connecting panel of bearing pin and sleeve the bottom of anchor shaft down, is provided with tapped bore and jackscrew matches between the tapped bore of nut and the thread surface on the following anchor shaft.
2, a kind of wire rope fixing device as claimed in claim 1, it is characterized in that: it is relative with bearing that sleeve wall is provided with lubricating cup.
