Preferably, between described the first joint and sliding wire, cushion block is installed also.
Preferably, on described jointing, filler strip is installed also.
Preferably, described draw runner is the V-arrangement draw runner, and it is combined by the multi-disc copper coin.
Preferably, the material of described sliding wire is aluminium or PVC or corrosion-resistant steel.
Preferably, described auxiliary bus bar is comprised of many tinned wires.
Compared with prior art, the utility model has the advantage of: adopt the compensation of gapless formula, namely two compensating part guide rods connect sliding wire, and erection joint thereon and locating axle seat, the rigidity that has realized device is strong, thereby rectilinearity and stable and continuous when having guaranteed current colector by this compensating device are reliable, can not produce and beat and spark phenomenon, and the accuracy of positioning when having guaranteed telescopic variation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the constructional drawing of new type of safe trolley temperature compensation means of the present utility model.
Description of reference numerals: 1, draw runner, the 2, first compensating part guide rod, the 3, second compensating part guide rod, 4, sliding wire, 5, the axis of guide, the 6, first joint, 7, jointing, 8, the second joint, 9, auxiliary bus bar, 10, lower locating axle seat, 11, upper locating axle seat, 12, guide pipe, 13, cushion block, 14, filler strip.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
consult shown in Figure 1, a kind of new type of safe trolley temperature compensation means that the utility model provides, it comprises the first compensating part guide rod 2 and the second compensating part guide rod 3 that connects by draw runner 1, respectively with the first compensating part guide rod 2 be connected two sliding wires 4 that compensating part guide rod 3 is connected, and two locating axle seats that are installed on the first compensating part guide rod 2 and the second compensating part guide rod 3 upper ends, and two locating axle seats connect by the axis of guide 5, the first joint 6 is installed on the first compensating part guide rod 2 and sliding wire 4, jointing 7 is installed on the second compensating part guide rod 3, and be positioned at the second joint 8 is installed on the sliding wire 4 of the second compensating part guide rod 3 one ends, the first joint 6 is connected with jointing 7 by auxiliary bus bar 9.And auxiliary bus bar 9 is comprised of many tinned wires, and it can guarantee the continuity of rated current.
Adopt like this a new type of safe trolley temperature compensation means of such scheme design to realize that the rigidity of device is strong, thereby guaranteed that rectilinearity and stable and continuous when current colector passes through this compensating device are reliable, can not produce and beat and spark phenomenon, and the accuracy of positioning when having guaranteed telescopic variation.The safety sliding contact line temperature compensation means of present embodiment is actual is a kind of safety sliding contact line gapless formula temperature compensation means.
Further, in the utility model, locating axle seat comprises lower locating axle seat 10, be installed on the upper locating axle seat 11 on lower locating axle seat 10, and be located at guide pipe 12 between lower locating axle seat 10 and upper locating axle seat 11, the axis of guide 5 is positioned at guide pipe 12, make locating axle seat with the axis of guide 5 as oriention benchmark, and then the accuracy of positioning when having guaranteed telescopic variation.And owing to also leaving the gap between the first joint 6 and sliding wire 4, be arranged on the upper end of sliding wire 4 and the first compensating part guide rod in order to make the first joint 6 pulsation-frees, between the first joint 6 and sliding wire 4, cushion block 13 is installed also.Equally, filler strip 14 also is installed on jointing 7.As preferably, draw runner 1 is the V-arrangement draw runner, is to be processed by the multi-disc copper coin to combine, and the current colector when it has guaranteed work passes through continuously continuously.
