Abstract
A transmission cable laying structure of an electric slab clamp comprises a connecting terminal box mounting on a crane trolley, a cable slot, an upright column disposed on a horizontal cross beam of the electric slab clamp and an electric slab clamp wiring terminal box arranged on a guide beam of the electric slab clamp. The transmission cable laying structure is characterized in that the crane trolley is fixedly provided with a downward-leading threading sleeve, power of the electric slab clamp and a laying structure control a cable to be led out to the cable slot from the inside of the connecting terminal box on the crane trolley, the cable from the cable slot penetrates into the downward-leading threading sleeve, and after penetrating out from the downward-leading threading sleeve and freely suspending, the cable is connected with the electric slab clamp connecting terminal box via the upright column on the horizontal cross beam of the electric slab clamp. The transmission cable laying structure removes a cable drum so that the cable suspends naturally, arc-shaped radius of the suspending cable is larger than 1 meter (bending force of the cable is minimized), and the largest tension born by the cable is one-third of the weight of the transmission cable so as to greatly reduce damage of the cable, thereby greatly prolonging service life of the cable.
Description
Technical field:
The utility model is specifically related to the cable transmission laying structure of electric bar plate clamp.
Background technology:
Metallurgy is assisted operation with electric bar plate clamp by crane, be that electric bar plate clamp is to be played by the lifting elevator on the crane dolly to move up and down, operation moves before and after driving electric bar plate clamp before and after the crane dolly, walking drives crane dolly and electric bar plate clamp side-to-side movement about the crane cart, the power of electric bar plate clamp and the laying structure of control cable are the binding post case outgoing cables from the crane dolly, cable is by the cable trunking on the dolly, passes through the binding post case of machinery (spring) cable drum to the slab clamp again.This transmission laying structure, there is following deficiency: because control and drive the high temperature-resistant cable that cable is 2.5 square millimeters in 1.5 square millimeters in 48 cores and 32 cores (or 28 cores 2.5 square millimeters), and the diameter of machinery (spring) cable drum only is 400 millimeters, and the adjustable height of clamp is 12 meters.Clamp is at any time, any height controlling and driving cable all will be subjected to the pulling force and the crimp force of cable drum, clamp when lowest order, the pulling force maximum that cable is subjected to (big to can with 40 millimeters angle steel stretch bending distortion); The pulling force minimum that clamp cable when highest order is subjected to, and crimp force maximum (mechanical spring reel will on the reel of 400 millimeters of diameters) 30 millimeters coils of cable of diameter; Because the frequent lifting of clamp, cable is also rolled along with the lifting of clamp or is stretching, causes cable very short useful life, cable often rupture (short life less than a week, a longest season); The mechanical spring reel is owing to will overcome cable gravity and will be cable hank on the reel of 400 millimeters of diameters, and frequent movement, spring fatigue, and the fault that often has spring fatigue to break spring also has volume not play the phenomenon of cable.Faults such as no matter the disconnected core of cable is disconnected strand, and still the reel spring is disconnected all directly influence orderly production, and changing a cable needs two hours, and changing a cable drum need four hour, and the maintenance cost height causes the normal operation ratio reduction of equipment.
Summary of the invention:
In order to improve the useful life of cable, the utility model provides the cable transmission laying structure of electric bar plate clamp.
The realization the technical solution of the utility model is: comprise the binding post case that is installed on the crane dolly, cable trough, be arranged on the column on the slab clamp horizontal gird, be arranged on the slab clamp binding post case on the slab clamp guide beam, it is characterized in that being installed with down on the crane dolly and draw the threading sleeve pipe, be drawn out to cable trough its power and the control cable binding post case from the crane dolly, the line that is come out by cable trough penetrates down and draws the threading sleeve pipe, draw down under the cable freedom that the threading sleeve pipe passes outstanding after, pass through the column on the slab clamp horizontal gird again, be connected with slab clamp binding post case then.
The utility model has been banned cable drum, make cable outstanding down naturally, the pulling force that the arc radius of the cable of following outstanding part bears greater than 1 meter (bending force of cable is reduced to minimum), cable is 1/3rd of transmission cable weight to the maximum, damage to cable alleviates greatly, so the life-span of cable prolongs greatly.And do not had the fault of cable drum to change the time, saved the expense investment of cable drum and spare part, the cable maintenance simple, intuitive is changed simple and fast.
Description of drawings:
Fig. 1 is the structure chart of the utility model embodiment.
Among the figure, 1, the crane dolly, 2, the binding post case on the crane dolly, 3, the cable trough on the crane dolly, 4, the threading sleeve pipe, 5, cable, 6, column, 7, the slab clamp horizontal gird, 8, slab clamp binding post case, 9, the slab clamp guide beam.
Embodiment:
Embodiment: shown in Figure 1, present embodiment comprises the binding post case 2 that is installed on the crane dolly 1, cable trough 3, be arranged on the column 6 on the slab clamp horizontal gird 7, be arranged on the slab clamp binding post case 8 on the slab clamp guide beam 9, it is characterized in that being installed with down on the crane dolly 1 and draw threading sleeve pipe 4, be drawn out to cable trough 3 its power and the control cable line 5 binding post case 2 from crane dolly 1, the line that is come out by cable trough 3 penetrates down and draws threading sleeve pipe 4, after drawing cable 5 that threading sleeve pipe 4 passes down and freely descending to hang, pass through the column 6 on the slab clamp horizontal gird 7 again, be connected with slab clamp binding post case 8 then.
