Description

For the spanner of guide gap sensor

Technical field

The utility model relates to guide gap sensor technical field, is specifically related to a kind of spanner for guide gap sensor.

Background technology

High-speed maglev train in running, without the need to contacting between vehicle with track.Magnetic-levitation train utilizes suspension system and guidance system, and to realize, vehicle body is vertical to lead with the suspension of side direction, and wherein guidance system comprises guide controller and guiding electromagnet module.In each guiding electromagnet module, be provided with 4 guide gap sensors, they utilize the nested magnetic pole bosom being arranged on guidance magnets module of bolt respectively, and distance operating surface is darker.Simultaneously see Fig. 1, one end of guide gap sensor 100 ' is connected by hexagon socket head cap screw 110 ' with fixed strip 200 ', and the other end of guide gap sensor 100 ' is connected with high-speed maglev train bogie structure 300 '.For the installation of hexagon socket head cap screw 110 ', can only carry out from the direction of vertical high-speed maglev train bogie structure 300 '.And hexagon socket head cap screw 110 ' is operated through after installing hole 310 ' according to action need.This operation easier is well imagined.

Installing plate 300 ' is offered multiple installing hole 310 '.Guiding electromagnet, levitating electromagnet 200 ' and trailing arm 100 ' surround a semiclosed region, make guide gap sensor to remove and install space less.

In limited operating space, utilize existing extracting tool, remove and install more difficult, holding time is more of a specified duration, especially when being equipped with 64 guide gap sensors in a high-speed maglev train, if carry out dismounting maintenance to whole car or the guide gap sensor of permutation car, whole process is consuming time longer.On the other hand, guide gap sensor shell is that casting aluminium material is made, installing hole is arranged on four corners of housing, structural strength and the tension stress-bearing capability of aluminium are all more limited, in the operating process of installing/dismounting, general erecting tools is adopted to dismantle, once misplacing appears in the installing hole of the guide gap sensor installing hole corresponding with on guiding electromagnet, then more easily cause installing hole stress deformation on housing, cause guide gap sensor to be destroyed.

Utility model content

Detailed description of the invention

The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.

See Fig. 2 ~ 3, the spanner for guide gap sensor that the utility model provides comprises L-type extension rod and is arranged at the hex nut mounting head 140 on L-type extension rod elongated end, the bottom surface of hex nut mounting head 140 is offered the hex nut installing hole for coordinating with hex nut outer wall, hex nut mounting head 140 arranges the face of magnetizing 141 that can produce magnetic attraction to hex nut away from the side of hex nut installing hole.Adopt L-type extension rod, hex nut mounting head 140 can be stretched into narrow operating area.Moment simultaneously by stretching out the L-type outside operating surface realizes the assembling to installing hole.During use, one end of L-type extension rod is stretched in narrow installation region, because band in hex nut mounting head 140 is magnetic, installation nut can better be carried and accurately arrive at installing hole and install.Rotate the L-type extension of L-type extension rod, complete the installation of nut.The assembling accuracy rate of the installing hole on housing on installing hole and magnet can also be improved, reduce the generation of mispairing.Improve the housing safety in utilization of guide gap sensor.Face 141 of magnetizing is set simultaneously, also the nut after dismounting can be held, prevent its access arrangement inside that comes off, and whole sensor need be taken apart and could be taken out.Can magnetize according to existing method in face of magnetizing 141 herein.

Preferably, L-type extension rod comprise kink 110, extension 120 that one end is connected with kink 110, extension 120 the other end be connected with connecting portion 130, the elongated end of connecting portion 130 is connected with hex nut mounting head 140.L-type extension rod is only and arranges bending near its one end place, can save material, increases and stretches into the degree of depth.

Preferred extension 120 and connecting portion 130 are for being threaded.Can be conducive to as required kink 110 being installed on other nut mounting rods, increase operation rate.

Preferably, also comprise multiple extension rod (not shown) for lengthening L-type extension rod, the two ends of extension rod are equipped with the screw thread that can be threaded with extension 120 and connecting portion 130 respectively.According to the degree of depth of installation site, extension rod can be increased, improve the scope of application of spanner.

Preferably, kink 110 with extension 120 for right angle bends.Decrease the moment of tightening required for sensor bolt to the full extent during right angle bending, reach the object that handled easily is safeguarded, improved the installing/dismounting efficiency of guide gap sensor.

Preferably, hex nut mounting head 140 and connecting portion 130 are for being threaded.Adopt this structure, hex nut mounting head 140 can be changed as required, make this spanner can use the installation and removal of multiple nut.

Preferred, kink 110 is 450mm with the spacing of hex nut mounting head 140.Now operate most convenient, most effective.

Composition graphs 1 is known, and during use, the extension 120 of L-type extension rod, through installing hole 310 ', directly acts on and installs hexagon socket head cap screw 110 '.Easy and simple to handle, avoid the damage to miscellaneous part is installed.Improve operating efficiency.
