Description

Auxiliary measuring scale for displaying pull-out value on rigid contact network

Technical Field

The utility model relates to a rail transit engineering field especially relates to a supplementary dipperstick that shows pulling-out value on rigid contact net of subway engineering rigid contact net adjustment.

Background

The bus bar is widely used as a rigid contact network for supplying power to vehicles in a subway tunnel, and during the construction of the rigid contact network of the subway tunnel, the height of the rigid contact network arranged at the top of the tunnel relative to a ground track needs to be adjusted, and a pull-out value is the distance between contact lines on two sides of the center of a track line and positive and negative runout of the track center, the shape of the contact lines relative to the positive and negative runout of the track center is similar to a sine wave, and a carbon brush of a pantograph is in contact with the contact lines and slides left and right within a certain range when a locomotive runs, so that the carbon brush of the pantograph is ensured.

At present, a method for adjusting the pull-out value of a rigid contact net of a subway tunnel is to arrange a guiding rule in the vertical direction of a track, scale marks are marked on the guiding rule, a laser measuring instrument is placed on the guiding rule to slide left and right, a laser beam is applied to an upper contact line, and an operator at the lower part measures the distance between the laser beam and the center of the guiding rule, namely the pull-out value. Another method is to directly place the laser measuring instrument on the rail, and the laser beam is hit on the upper contact line, and the leading-up and the pulling-out values are displayed through a triangular algorithm in the instrument. In both methods, the operator on the upper part of the work vehicle cannot directly read the pull-out value, the lower measuring operator needs to report the number to the upper operator orally, and the upper operator readjusts the bus bar support according to the heard data until the pull-out value meets the requirement. Obviously, the upper part adjusting personnel of the working vehicle cannot visually see the pull-out value and needs an indirect oral reporting method by the following personnel, so that the defects of inconvenient operation of the adjusting personnel and low adjusting efficiency are caused.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The structure and operation of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1-3, the utility model discloses an embodiment of an auxiliary measuring ruler that shows pulling-out value on rigid contact net, including reading chi 8 and walking the line mechanism, reading chi 8 is made by the transparent material who is carved with the scale, becomes the vertical direction with rigid contact net and is connected with walking the line mechanism, walks the line mechanism and hangs in rigid contact net lower part, and can follow the line direction motion of rigid contact net.

The reading ruler 8 is a long strip-shaped ruler, a 0 bit line 8.1 is marked in the middle, and reading lines which are spaced are marked along the length direction of the two direction-measuring reading rulers 8 extending from the 0 bit line. The reading ruler 8 is preferably made of transparent material and faces downwards.

The walking mechanism comprises a roller 2, a roller shaft 4, a clamping plate 3, a spacing sleeve 5, a spacing sleeve connecting bolt 7, a connecting bracket 6 and other accessories. Wherein a tip that roller 2 installed at roller axle 4 can the free rotation, bolted connection is passed through on splint 3 in the other one end of roller axle 4, roller 2 is equipped with rim 2.1, this rim 2.1 blocks flange plate 1.1 of busbar 1 lower part, install two sets of rollers 2 on every splint 3, two the same splint 3 symmetric distribution, it is fixed through spacer 5 and spacer bolt 7 each other, the length of spacer 7 guarantees that roller 2 of two bisymmetries can freely roll and can not produce the removal of walking between the mechanism is horizontal along the flange plate 1.1 of busbar lower part.

One end of splint 3 is consolidated and is had linking bridge 6, and reading chi 8 passes through linking bridge 6 to be connected at walking mechanism one end tip, is with rivet 9 fixed connection between this embodiment reading chi 8 and the support 6, and of course in other embodiments, reading chi 8 also can adopt the joint mode that prior art is commonly used to be connected with support 6, can dismantle reading chi, portable walking mechanism fast when not using like this. When the reading ruler 8 is attached, care is taken to align the 0 bit line with the center of the running gear in the plumb direction, i.e. with the midpoint of the bus contact line 10, to ensure that the reading ruler 0 bit line coincides with the midpoint of the bus contact line 10 in the plumb direction.
