Description

A quick change device for tow cable block

technical field

The utility model relates to the technical field of equipment maintenance, in particular to a quick replacement device for a tow cable block.

Background technique

As the key equipment in the production line of iron and steel enterprises, the liquid casting crane is mainly responsible for ensuring that liquid metals such as molten iron and steel enter the converter and upper casting machine safely and smoothly. The power cables and control cables for the operation of the main and auxiliary trolleys and the operation of the main and auxiliary coils are all passed through the tow cable pulley installed on the I-beam bracket next to the main and auxiliary trolleys, and the cables are fixed in sections by multiple double-layer cable pulleys. .

Taking the 200t liquid crane as an example, dozens of cables with different capacities are bundled into a cable bundle. The cable bundle with a length of about 50 meters weighs about 1 ton. It is connected and fixed by 10 cable pulleys. As the trolley moves, the cables The pulley moves along with the cable, referred to as the tow cable. During operation, each pulley bears a section of tow cable with a weight of nearly 100kg. Due to the environment, stability and other reasons, the connecting pins and wheels of the trolley wear out quickly. In addition, they are exposed to high temperature and dust for a long time, and the bracket of the trolley is damaged and the wheels of the trolley are often damaged. Breaking will affect production and safety, and it is necessary to replace the trolley and pulleys regularly to ensure the free expansion and contraction of the tow cable. In the past, at least 3 people were required to cooperate in the replacement. 2 people held up the cable to make the tow cable unstressed and 1 person removed the sheave bolts to complete the replacement.

Utility model content

In order to solve the above-mentioned technical problems, the utility model provides a quick replacement device for the tow cable block, which solves the problem of low efficiency in the replacement and maintenance of the tow cable block. The car body and wheels of the tow cable block are replaced, and the maintenance manpower is saved, and the cost is reduced.

In order to achieve the above object, the technical solution adopted by the utility model to solve the technical problem is: the quick changing device of the tow cable block is fixed on the I-beam matched with the tow cable block, and it is characterized in that it includes a rotating drum, A support rod and a tow rope, the rotating reel is rotatably connected to one end of the support rod, the tow rope is wound on the rotating reel and connected to the other end of the support rod through the tow rope.

Further, the rotating reel is provided with a locking mechanism for locking the tow rope.

Further, the locking mechanism is configured as a ratchet mechanism including a ratchet and a pawl, the ratchet is fixed at one end of the rotating reel, and the pawl is disposed on the support rod.

Further, a support frame is provided on the support rod, and the support frame is rotatably connected to the ratchet through a rotating shaft.

Further, the rotating reel is connected with one end of the support rod through a bearing.

Further, a driving component is fixed at one end of the rotating reel.

Further, the driving component is configured as a motor or a manual rocker.

Further, the rotating reel is set as a hollow cylinder.

Further, the I-beam is provided with a fixing seat, and the support rod is fixed through the fixing seat.

The beneficial effects of the utility model are:

The quick changing device of the tow cable tackle is fixed on the I-beam of the tow cable tackle, so that the tow rope goes around the bottom of the tow cable tackle, and the tow rope is wound around the tow rope by rotating the reel, so that the tow rope drags the tow cable tackle, so that the tow rope The pulley is separated from the I-beam, which is convenient and quick to operate, saving manpower for maintenance and reducing costs;

Further, the rotating reel is also provided with a locking mechanism for locking the tow rope. The locking mechanism is set as a ratchet mechanism. When the tow rope is wound under the rotation of the rotating reel, the ratchet mechanism also operates accordingly. After the length is adjusted, the ratchet mechanism also stops running, and the ratchet is inserted into the ratchet to lock the position of the rotating reel, which further saves manpower.

To sum up, the quick-change device for the tow cable block has a simple and compact structure, is convenient and safe to operate, saves maintenance manpower, and reduces costs.

Detailed ways

The specific implementation of the present utility model will be described in further detail below through the description of the best embodiment with reference to the accompanying drawings.

The specific embodiment of the utility model is as follows: as shown in accompanying drawing 1 and accompanying drawing 2, a kind of tow cable block quick change device is fixed on the I-beam that cooperates with tow cable block, comprises rotating reel 1, support bar 2 and a tow rope 3, the rotating reel 1 is rotatably connected to one end of the support rod 2, and the tow rope 3 is wound on the rotating reel 1 and connected to the other end of the support rod 2 through the tow rope 3.

The rotating reel 1 is provided with a locking mechanism 4 for locking the tow rope 3. The locking mechanism 4 is configured as a ratchet mechanism including a ratchet 41 and a pawl 42. The ratchet 41 is fixed on one end of the rotating reel 1, and the ratchet 42 is provided On the support rod 2, the support rod 2 passes through the fixed seat 8 provided on the I-beam and is fixed on the I-beam. When the rotating reel 1 rotates, the ratchet 41 also rotates. After the rotating reel 1 stops rotating, the ratchet 41 also stops rotating.

The rotating reel 1 is connected to one end of the support rod 2 through a bearing 6, and the support rod 2 remains stationary when the rotating reel 1 rotates, so that the overall structure is stable; one end of the rotating reel 1 is fixed with a driving part 7, and the driving part 7 is arranged as The motor or manual rocker makes the use more convenient and labor-saving; the rotating reel 1 is set as a hollow cylinder, the overall weight is lighter, and the rotation is more labor-saving.

Embodiment: The use process of the tow cable tackle quick replacement device is: first fix the fixing seat 8 on the I-shaped steel, make the tow rope 3 wrap around the bottom of the tow cable tackle, and then start the motor or manually operate the manual rocker to make The tow rope 3 is wound on the rotating reel 1, the tow rope 3 is gradually shortened, and the tow cable block is pulled up to separate the tow cable block from the lower part of the I-beam, so that the rotating reel 1 stops rotating, and the ratchet 41 also stops at the same time. Rotate, the ratchet 42 snaps into the ratchet 41 to lock and position the position of the rotating drum 1, and then perform maintenance and replacement. After the repair and replacement is completed, open the ratchet, rotate the rotating drum 1 in the opposite direction and slowly lower the tow cable block, Restore the tow block to its normal working position.

Judging from the implementation situation, it only takes 5 minutes for a maintenance worker to install and lift the trolley. Since the device has a self-locking function, it is safe and reliable. The overhaul personnel can work with both hands with confidence, and the speed of disassembling the car body or wheels is faster, and the whole overhaul time only takes 20 minutes. The maintenance man-hours for each group of small blocks has been shortened from 3 man-hours in the past to 0.2 man-hours now, and the maintenance efficiency has been greatly improved.
