About the termination of two conductions on the barred body be connected with can with about two soft lines of conduction barred body bonded assembly.
In such scheme, a described conduction barred body places and is arranged on the casing of hydraulic pump in and the barred body guide hole that direction is opposite parallel with the Hydraulic Pump cylinder body, and another root conduction barred body places in the Hydraulic Pump cylinder body.
In such scheme, described conduction barred body adopts copper pipe, and gauge head adopts brass rod, and soft line adopts braiding red copper flexible cord.
The utility model is as audio frequency jointless track circuit primary parameter measuring tool, distance between the web of the rail of its length and two one steel rails equates, adjusting leeway should be arranged, this test bar can be made short bar and send torch to use, it has simple in structure, operate advantage easy to carry, be particularly suitable for audio frequency jointless track circuit primary parameter and measure.
Description of drawings
Fig. 1 is the constructional drawing of the utility model as short bar.
Fig. 2 is that the utility model is as the constructional drawing that send torch.
The specific embodiment
Embodiment 1: the utility model is as short bar.
With reference to Fig. 1, this short bar by about the two left barred bodies 1 that are arranged in parallel, right barred body 2 and Hydraulic Pumps 3 form, left barred body 1 and right barred body 2 adopts the copper pipe of external diameter 34mm, endoporus ￠ 27mm.Described left barred body 1 place be arranged on the casing of hydraulic pump coaxial with Hydraulic Pump cylinder body 4 and barred body guide hole 5 that direction is opposite in, right barred body 2 places in the Hydraulic Pump cylinder body 4, and links to each other with the plunger of Hydraulic Pump 3.Gauge head 6 is equipped with in barred body outer end, the left and right sides, and every barred body is provided with termination, soft line 9 by be arranged on the barred body termination with about two barred bodies couple together.
Above-mentioned Hydraulic Pump 3 adopts hydraulic hand-pump; Gauge head 6 adopts the H62 brass rod of 34; Soft line 9 adopts braiding red copper flexible cord; Termination is made up of touch block 7 and connection bolt 8, and to guarantee comprising contact resistance, the resistance of whole short bar should be less than 100 milliohms.
When this short bar uses, at first two barred body the inners are put into guide hole on Hydraulic Pump cylinder body and the casing of hydraulic pump respectively, the gauge head of barred body is aimed at the railway track inner side waist, will polish totally in the place that rail contacts with gauge head, and contact is kept in good condition.Tighten the release knob of Hydraulic Pump then, come and go and press pressurized handgrip, make gauge head hold out against rail,, between the rod end and the web of the rail 300 kilograms of pressure should be arranged at least for reducing the contact resistance of the rod and the web of the rail; Drop into normal the use.After finishing using, first release handle, the oil cylinder release can be taken off rod.
The utility model comprises contact resistance in use, and the resistance of whole rod should be less than 100 milliohms.
Embodiment 2: the utility model is as sending torch.
With reference to Fig. 2, originally send torch by about the two left barred bodies 1 that are arranged in parallel, right barred body 2 and Hydraulic Pumps 3 form, left side barred body 1 and right barred body 2 adopt the copper pipe of external diameter 34mm, endoporus 27mm, described left barred body 1 place be arranged on the casing of hydraulic pump coaxial with Hydraulic Pump cylinder body 4 and barred body guide hole 5 that direction is opposite in, right barred body 2 places in the Hydraulic Pump cylinder body 4, and links to each other with the plunger of Hydraulic Pump 3.The centre of right barred body is provided with insulation barred body 10, with nylon 66 nylon rods of 34.Insulation barred body 10 two ends are provided with two touchs block 7.Gauge head 6 is equipped with in barred body outer end, the left and right sides, is provided with termination on the barred body of left barred body 1 and right barred body 2, soft line 9 by be arranged on the barred body termination with about two barred bodies connect.
