Description
Technical field
The utility model relates to a kind of connecting device, specifically, is the connecting device that is used to connect current colector on the coil of strip dolly that feed is used.
Background technology
At present, on the coil of strip lane of traffic of hot rolling conveyer chain system, the automatic coil of strip travelling bogie that generally adopts wire communication and wireless telecommunications Comprehensive Control is responsible for cold rolling production feed in circular orbit cocycle operation.The coil of strip travelling bogie is the logistics lifeline of cold rolling production, and the quality of its equipment state is directly connected to cold rolling ordinary production and logistics balance.
But there is following shortcoming in coil of strip travelling bogie in use at present:
1, because the connection mode of dolly current colector is that an end is fixed, the other end is a free open type band iron structure, this dolly current colector only depends on a band iron to carry out loosely connected, so it does not possess the automatic compensation function of axial automatic compensation and radial position, current colector is usually because of differential settlement, the distortion of the electric road body of wall that rubs, the sedimentation of circular orbit, or the shake in the operational process and dolly communication failure and current colector release failure take place, cause dolly to be stopped transport, and the attaching plug of current colector damage.
2, the connecting rod of dolly current colector adopts single-point to fix, and the some contact for free form easily comes off; In operational process, the inclination that current colector existence in various degree is certain, cause the chute run-off the straight of current colector in Mo Diandao, cause the rolling wheel wear inequality, the friction drag of operation increases, the stuck situation of final generation, serious, also can cause 380V short circuit in the electric road that rubs, take place " blowing out ", thereby whole coil of strip dolly transport systems can't be moved, cause long machine halt trouble;
3, in addition, because coming off of dolly connecting rod directly causes the damage of the communication plug and the 380V attaching plug of dolly current colector.Electric road is an osed top equipment owing to rub, in the 1200 meters long electric road equipment that rubs, has only a unique unlatching mouth, dolly manually must be pushed to the open place, electric road of rubbing from circular orbit when changing current colector, need to surpass 1.5 hours processing time, have a strong impact on the direct sending rate of cold-rolled steel coils.
To this, (the patent No.: CN200620039319.6) that the applicant had before proposed a kind of " coil of strip dolly current colector universal connector ", this connecting device can be avoided the release failure of current colector, avoid because of the fault that the communication signal that track and the differential settlement of electric road body of wall of rubbing cause is lost, current colector power supply and Signal plug damage, avoid the current colector inclination that is in operation; Prolong the service life of current colector, improve the direct sending rate of cold-rolled steel coils, reduce maintenance, the maintenance load of equipment.Though this utility model has solved on-the-spot comparatively outstanding above-mentioned practical problems, in using at the scene, its complicated structure requires to cause the cost of equipment maintenance relative higher with high strength to material, and the applicant has done another kind of innovation for this reason.
The utility model content
The purpose of this utility model is to provide a kind of coil of strip dolly with the two bulb universal connectors of current colector, and this device is fixed, and is axial and radial motion is flexible, can overcome shortcoming of the prior art, and simple in structure, maintenance cost is low.
The utility model is achieved in that a kind of coil of strip dolly with the two bulb universal connectors of current colector, comprises distance adjusting means and angle regulator two parts;
Described distance adjusting means comprises dolly side connecting plate, anchor shaft and slip ball head; Dolly side connecting plate and coil of strip dolly are affixed, and anchor shaft left end vertical fixing is in the dolly side connecting plate, and the slip ball head comprises major axis and be fixed in first bulb of major axis right-hand member that major axis is that bar shell type bearing fit connects with anchor shaft;
Described angle regulator comprises first bulb, first ball-head cover, second bulb, second ball-head cover and the collector side connecting panel of slip ball head, and second ball-head cover left side is arranged in first ball-head cover, and both connect by screw thread fit; First bulb is positioned at first ball-head cover, first ball-head cover inner chamber left side is provided with a left side first spheric seating that matches with the first bulb sphere, second bulb is positioned at second ball-head cover, the second ball-head cover inner chamber right side is provided with second spheric seating that matches with the second bulb sphere, and the second ball-head cover left end also is provided with the right side first spheric seating that matches with the first bulb sphere; The second bulb right-hand member is fixed by a minor axis and collector side connecting panel, and collector side connecting panel and current colector are affixed.
As a kind of optimization, described first, second ball-head cover gives fasteningly by being arranged on two nuts on second ball-head cover and being arranged on two stop washer between the nut again, prevents that first, second ball-head cover is loosening.
As a kind of optimization, the described second bulb diameter is less than the first bulb diameter; Slip ball head, the second bulb inside offer cavity, and first, second bulb leading section is cut into platform structure, has so just reduced weight of the present utility model.
As a kind of optimization, described left first spheric seating left side also offers seal groove, and sealing member is installed in the seal groove, and outer end, first ball-head cover left side also offers peripheral chamfer; The described second spheric seating right side also offers seal groove, and sealing member is installed in the seal groove, and outer end, the second ball-head cover right side also offers peripheral chamfer.Obviously sealing member is used to seal angle regulator, and chamfering further enlarges the action radius of first, second ball-head cover.Anchor shaft and major axis mating part offer oil hole, and first, second ball-head cover mating part also offers oil hole, inject lubricating oil to give moving part.
As a kind of optimization, described anchor shaft is a hollow circular-tube, and the major axis of slip ball head is plugged in the pipe.
The utility model adopts soft bar shell type sliding matching structure and bulb steering structure combined, but make it at the automatic compensation that axially, directly makes progress, thereby the restriction that electric road body of wall and the current colector spacing of not rubbed when the coil of strip dolly is moved on circular orbit changes, the situation that the run signal that also is not subjected to the influence of the track and the electric road body of wall differential settlement that rubs and causes beating in the trolley travelling process to be caused is lost, improve the direct sending rate of cold-rolled steel coils, guaranteed the balance of logistics.All the time can guarantee that current colector connecting rod and current colector are connected firmly, avoid current colector to come off, damage.Can effectively solve the inclination of current colector at operational process, thereby the roller that has guaranteed current colector correct operation in Mo Diandao, guarantee the conformability of both sides rolling wheel wears, avoided current colector situation stuck and " blowing out " in Mo Diandao to occur, prolonged the service life of current colector.
The utility model has been realized more flexibly axially the automatic compensation that makes progress with the footpath and has been adjusted function, simple in structure, Material Strength is required to reduce relatively (with respect to the patent of the previous application of the applicant described in the background technology), further improve the advance and the service life of equipment, greatly reduced the cost of maintenance and the maintenance load of equipment.
