Abstract

The utility model discloses a protective device of power supply cables of a movable gantry crane. In order to overcome the disadvantages that: when the existing gantry cranes move in a reciprocating way, the power supply cables is driven to be bended in a reciprocating way, therefore, the cable sheath is damages, thus causing short circuit or potential safety hazards when in earthling, the protective device is provided; chains which can be connected with fixed ground-ring hinges can be clamped at one side of a fixed fixture on the outer diameter of the cables; when the gantry crane moves in a reciprocating way, the cables move with the gantry crane and pass through a rootage point of the fixture, due to the mobility of the chains and the fixation of the fixture, the direction of the cables can be changed with the change of the gantry crane direction in the moving process that the fixture on the cables move with the cables, thus preventing the cables from being bended rigidly and eliminating the potential safety hazards in the production. After being measured and calculated, after the protective device is used, according to that every institution has 40 gantry cranes, the direct and indirect economic benefit for eliminating potential safety hazards per year can reach ten thousand yuan to tens thousand of yuan.

Description

The fender guard of portable door machine supply cable

Technical field

The utility model belongs to a fender guard of machine supply cable line.

Background technology

In the daily use of span winch, because the needs of operation will constantly move and adjust job position.Giving the cable of the span winch power supply of mobile operating, is to be connected in the attached cable hole of electric supply installation.In the process of door machine walking, for preventing that the machine supply cable from drawing bad institute bonded assembly cable aperture, to such an extent as to the foreskin of scratch cable causes faults such as supply line's short circuit or ground connection, at present common way is that the dynamo-electric cable of door is banded in by the cable aperture with rope, as fixedly taking root a little of cable.Above-mentioned way has following bigger drawback: when the door machine back and forth operation make cable change towards the time, the dynamo-electric cable of door a little is fulcrum bending twisting repeatedly with taking root of rope, very easily cause the cable sheath damage, still faults such as short circuit or ground connection can appear, the potential safety hazard that can't avoid the production scene to exist.

The utility model content

Technical problem to be solved in the utility model is; overcome existing span winch when back and forth walking; drive supply cable back and forth bending cause the cable sheath damage, cause short circuit or ground connection to have the shortcoming of potential safety hazard, a kind of fender guard of portable door machine supply cable is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: in holding clamp one side that can be clipped on the outside diameter of cable, be connected with can with encircle hinged chain regularly.

The utility model also has following technical characterictic:

Described holding clamp be two relatively, fix cable clamp on the outside diameter of cable with bolt;

Between the epidermis on the described jig and the outside diameter of cable, para-electric cable length direction is provided with the abrasionproof rubber cushion that grows the jig two ends.

Advantage of the present utility model and good effect are; owing to be fixed with jig on the outside diameter of cable; jig one side is encircled with chain with being connected; when the door machine is back and forth walked; when cable moves through jig and takes root with the door machine; because the avidity of chain and the stationarity of jig; jig on the cable moves a segment distance with cable; in the process that moves, do to take root that with the jig on the cable certain mobile allowance is a little arranged, cable towards changing and finish commutation with the door machine; therefore avoided hard folding cable; thereby well protected cable, overcome the drawback that traditional cable mode of taking root bends cable, eliminated the potential safety hazard in producing.After calculating, using above-mentioned fender guard, have 40 door computer with per unit, the year direct and indirect economic benefit that realizes that eliminates safe hidden trouble reaches ten thousand yuan and even tens thousand of unit.

Description of drawings

Fig. 1 looks scheme drawing for master of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1,, be connected with the chain 3 of the end band collar 4 in the right side one side that can be clipped in the holding clamp 2 on cable 1 external diameter.During use, the bearing pin on the collar 4 4.1 is unloaded, be enclosed within on the ground on the fixing ground ring of correct position, and then bearing pin 4.1 installed the collar 4 is sealed.

Among Fig. 2, described holding clamp 2 is two relative, as to use bolt 5 to fix on cable 1 external diameter cable clamps (referring to Fig. 1).

In order further to protect cable 1 exocuticle; when door machine change of direction, cable 1 are finished commutation; avoid the two ends abrasive cut-off cable 1 of jig 2 to cause short circuit or ground connection; between the exocuticle on described jig 2 and cable 1 external diameter, the length direction of para-electric cable 1 is provided with the abrasionproof rubber cushion 6 (referring to Fig. 1) that grows jig 2 two ends.

Claims

1, a kind of fender guard of portable door machine supply cable is characterized in that: in holding clamp one side that can be clipped on the outside diameter of cable, be connected with can with encircle hinged chain regularly.

2, the fender guard of portable door machine supply cable as claimed in claim 1 is characterized in that: described holding clamp be two relatively, fix cable clamp on the outside diameter of cable with bolt.

3, the fender guard of portable door machine supply cable as claimed in claim 1, it is characterized in that: between the exocuticle on the described jig and the outside diameter of cable, para-electric cable length direction is provided with the abrasionproof rubber cushion that grows the jig two ends.
