Abstract
In a protective device for portal crane high-voltage cable, a fixed wear resistant rubber plate is positioned in the inboard of the cable channel which covers on the surface of the channel; a plurality of supports are mounted on the cable drum, a side of the supports which is close to the inboard of the cable channel provided with a plurality of sets of guide pulleys; the supports have a plurality of cable drive slits, the cable drive slits at the bend where the cable is stressed are provided with a limit switch, the limit switch serially connected with the control circuit of the cable drum. The utility model has simple structure and low cost, can effectively protect the cable, prevent the cable from breakage, damage and other accidents; and keep people from treading on the high voltage cable so as to ensure personal safety.
Description
Technical field
The utility model belongs to cable protecting device, particularly a kind of high pedestal jib crane high-tension cable fender guard.
Background technology
At present, the door machine is main loading and unloading weight-lifting equipment at each harbour, it is mechanical equipment important in the port operation, its power cable is to be introduced by the power cable reel by the ground lock case that is installed in quayside, thereby realized the supply of power supply, cable drum is typically provided with the warning device of some basic loose excessively, tensions, but in real process, also has following problem.
1. cable is in the folding and unfolding process, often go out cable duct: the door machine is in operation process, often need change the cabin, therefore get and often run cart, cable is in the folding and unfolding process, because cable duct is open-air, often has long-pending coal and dust in the ditch, if having little time cleaning, be everlasting in the time of certainly will filling up such cable to the ditch cable duct outside, sometimes be extruded, cause short circuit, cause very bad consequence, site work environment complexity in addition, in operation lump coal process, fall down lump coal easily and injure cable by a crashing object, influence the service life of cable.
2. cable duct is buried extremely easily: because cable duct is in the wharf apron, boats and ships are often wanted unballast after pulling in to shore, the long-pending coal that the cable groove is easy in the into water and groove mixes, be easy to when middle in the winter time freeze and freeze, cause cable and cable duct to connect together, the door machine in the process of walking like this, overcome powerful resistance, gently then cause cable impaired, insulation resistance value reduces, and is heavy then cause and pull apart cable, cause cable short circuit, consequence is hardly imaginable.
3. worker's cable of often stepping on, cable protection is bad very easily to cause electric shock.Above-mentioned three situations all can cause cable fault in various degree, very easily cause cable fault, and hazardous accidents very easily takes place, and on safety personnel are had the injury of electric shock, cause very big loss and safety responsibility accident.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of high pedestal jib crane high-tension cable fender guard is provided.The device of bitter automatically lid cable when it is a kind of moving door machine, and under the situation of cable exertin, the control gate machine stops the device of traveling immediately.Reach the protection high-tension cable, prevent that high-tension cable is pressed down and pulls apart.
The technical solution of the utility model is:
A kind of high pedestal jib crane high-tension cable fender guard is characterized in that: install and fix one side of wear-resisting rubber board at the ground surface of cable duct near the inboard of high pedestal jib crane, wear-resisting rubber board width covers the cable duct surface greater than the cable duct width; Mounting bracket on the cable drum of high pedestal jib crane, the one side near the cable duct inboard on support is equipped with many group track adjusting wheels; Have a plurality of cable transmissions to roll on the support, the cable transmission of the position of turning round that cable is stressed on support rolls on the installation limit switch, and limit switch is connected in series in the control loop of cable drum.
Support is the three-dimensional bracket of a similar convex shape, and convex shape support top is installed the cable transmission and rolled, and the axle horizontal direction that transmission is rolled is perpendicular to the high pedestal jib crane side; Many group track adjusting wheels are installed in convex shape support bottom, and track adjusting wheel is between convex shape support bottom and high pedestal jib crane side, and guide wheel shaft is perpendicular to ground.
The utility model effect is:
This apparatus structure is simple, and is cheap, can protect cable effectively, avoids cable to be torn, the generation of abominable accident such as breakage, and in personal injury, the personnel that can the play high-tension cable of directly not stepping on guarantees personal safety.Two in my company existing door machine, two of power cables, but the quantity of door machine is quite huge full harbor office, cable be compromised and the accident that is short-circuited a lot, my company has been installed additional after this automatic cladding system, and a cable fault accident never took place, only this item is that company saves 200,000 yuan of maintenance costs, as consider the loss that stops production, the accumulation benefit will reach ten thousand yuan of 60-70, and the development cost of this device is 30,000 yuan.And this technology has important promotional value in port loading and unloading machinery.

Fig. 2 is the cable duct structure side view of high pedestal jib crane high-tension cable fender guard
Fig. 3 is the control loop circuit diagram that limit switch is connected on cable drum
Fig. 4 is the cable duct running condition scheme drawing of high pedestal jib crane high-tension cable fender guard
Among the figure: control loop, the 8 cable transmissions of 1 cable duct, 2 wear-resisting rubber boards, 3 cable drums, 4 supports, 5 track adjusting wheels, 6 limit switches, 7 cable drums are rolled, 9 cables
The specific embodiment
As 1,2,3 as shown in the figure
1. automatic bitter lid arrangement
One side of the wear-resisting rubber board 2 that installs and fixes in the inboard of the close high pedestal jib crane of cable duct 1 ground surface, wear-resisting rubber board width covers the cable duct surface greater than the cable duct width; Convex shape support 4 is installed on the cable drum 3 at high pedestal jib crane, many group track adjusting wheels 5 are being installed near the convex shape support bottom of the inboard of high pedestal jib crane, track adjusting wheel is between convex shape support bottom and high pedestal jib crane side, and guide wheel shaft is perpendicular to ground.Convex shape support 4 tops are equipped with a plurality of cable transmissions and are rolled 8.The axle horizontal direction that transmission is rolled is perpendicular to the high pedestal jib crane side.
After rubber just can be gone into groove along with cable when the folding and unfolding cable like this, cover cable while walking, dust and the odd job chance that enters cable duct 1 just significantly reduces like this, thereby has protected cable 9.
2. cable overpressure protection device
Cable is being subjected under the situation of exertin, rolls 8 in the cable transmission of the position of turning round a limit switch 6 is installed, and switch series is linked in the control loop of cable drum as shown in Figure 4.So in a single day the situation limit switch action of cable tension takes place, and control loop has stopped the traveling of control gate machine like this, thereby has protected cable.
