Description
Technical Field
The utility model relates to a tower crane technical field, concretely relates to tower machine wire rope dish rope preloading device.
Background
The tower crane hoisting mechanism and the luffing mechanism need to be debugged on line before leaving factory, and the steel wire rope is wound according to a product configuration table. Every wire rope reel all twines kilometer wire rope, and the wire rope reel needs place on the wire rope rack, and its winding mode is through mechanism drive wire rope reel rotation, then with the wire rope finally shift to mechanism's reel on.
In the prior art, the end of the steel wire rope placing frame is in a free state, three persons are needed to operate in the process of winding the steel wire rope, one person guides the steel wire rope, one person compresses the steel wire rope, and one person controls the power supply. Because wire rope placing frame end is in free state, there is not the pretightning force in the wire rope winding process, and wire rope beats badly in the winding process, even if there is the special messenger to compress tightly wire rope, also leads to wire rope skipping, indiscriminate rope, phenomenons such as lax easily, and this kind of mode has reduced wire rope wiring time length, wiring efficiency, has increased the human cost, and the wiring effect is relatively poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tower machine wire rope dish rope preloading device to solve the rope skipping and the relaxed problem that appear of the wire rope that exists among the prior art when the reel.
In order to achieve the purpose, the utility model discloses a tower machine wire rope coiling pre-tightening device, which comprises a coiling block bracket and a resistance mechanism, wherein the coiling block bracket comprises a rotating shaft and two disks, the two disks are arranged in parallel and are perpendicular to the rotating shaft, and the circle center of each disk is positioned on the axis of the rotating shaft; the resistance mechanism is positioned on the outer side of the winding drum support and comprises an additional shaft, blades and a box body, the additional shaft is positioned on the outer side of the disc and is fixedly connected with the rotating shaft, the axis of the additional shaft is overlapped with the axis of the rotating shaft, the blades are fixed on the additional shaft through a connecting rod, and the blades are perpendicular to the disc; the box body is arranged below the additional shaft, resistance liquid is filled in the box body, and the blades can rotate in the box body.
Further, the two resistance mechanisms are respectively positioned on the outer sides of the reel supports.
Further, the number of blades provided for each resistance mechanism is greater than or equal to two.
The utility model has the advantages that: two resistance mechanisms are arranged on the outer side of the reel bracket,
every resistance mechanism passes through the blade and rotates in the resistance liquid in the box, when installing the wire rope reel on the reel support, wire rope can drive the reel support rotation when taking out from the reel support, at this moment, owing to set up two resistance mechanisms, its rotation can speed relatively slow and steady, wire rope just can not appear skipping, the condition of slack in advancing to its serving efficiency has been improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, a tower crane steel wire rope coiling pre-tightening device comprises a coiling block support 1 and a resistance mechanism 2, wherein the coiling block support 1 comprises a rotating shaft 11 and two disks 12, the two disks 12 are arranged in parallel and are perpendicular to the rotating shaft 11, and the circle center of each disk 12 is positioned on the axis of the rotating shaft 11; the resistance mechanism 2 is positioned on the outer side of the reel bracket 1, the resistance mechanism 2 comprises an additional shaft 21, blades 22 and a box body 23, the additional shaft 21 is positioned on the outer side of the disc 12 and is fixedly connected with the rotating shaft 11, the axis of the additional shaft 21 is overlapped with the axis of the rotating shaft 11, the blades 22 are fixed on the additional shaft 21 through connecting rods, and the blades 22 are vertical to the disc 12; the box 23 is arranged below the additional shaft 21, resistance liquid is filled in the box 23, and the blades 22 can rotate in the box 23. The two resistance mechanisms 2 of the embodiment are respectively positioned at the outer sides of the reel bracket 1. The drum support 1 is used for mounting a steel wire rope drum, and the working purpose of the drum support is to convey a steel wire rope on the drum to a hoisting mechanism or a luffing mechanism. In prior art, because reel support 1 when wire rope breaks away from the reel, reel support 1 can turn very fast, uncontrolled, consequently, the phenomenon of rope skipping, indiscriminate rope and lax will appear in the wire rope that leaves the reel body, the difficulty in arrangement has been increased for field personnel, among this technical scheme, through setting up resistance mechanism in reel support 1 both sides, when wire rope breaks away from the reel, owing to receive resistance mechanism's hysteresis, it will be slower to break away from speed, consequently can be more stable, wire rope will be in the state of tightening, this is a normal state, consequently, field personnel will become very easy to wire rope's arrangement.
In the present embodiment, the number of the blades 22 provided for each resistance mechanism 2 is greater than or equal to two, and the specific number is selected according to the field situation. The resistance liquid in the tank 23 is water, but may be other liquid.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes that can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art can be made within the scope of the claims of the present invention.
