Abstract
The utility model discloses an induction position switch device, which comprises a fixing sleeve, a left cover and a right cover. The left cover and the right cover are fixed on the left end and the right end of the fixing sleeve respectively. A tightening joint is fixed at the lower right end of the fixing sleeve, and a flexible pipe is fixed at the lower end of the tightening joint. The induction position switch device provided by the utility model can enable a leveling sensor not to be limited in measurement.
Description
Technical field
The utility model belongs to a kind of device in the railway maintenance machinery checkout equipment, relates in particular to a kind of sensed position switchgear that is applied to leveling sensor.
Background technology
Existing leveling sensor, controlled and limited sensor operation stroke by upper and lower two groups of eccentric rods.Eccentric rod plays common road conditions and special road conditions is defined, during common road conditions, large-scale maintenance machinery can carry out the continous way automatic job, can carry out manual operation targetedly during special road conditions, if but automatic Railway Condition is poor, while exceeding the operation stroke that leveling sensor limits, leveling sensor can't measure the real data of road conditions.If cancellation eccentric rod, although leveling sensor can carry out not limited measurement, work as road conditions special, when the test data of leveling sensor is transferred to operation bench, operating personnel can not be judged road conditions timely and accurately, thereby can affect homework precision and the efficiency of large-scale maintenance machinery.
Although prior art is improved the existing weak point of leveling sensor, as Chinese patent Granted publication number: CN2869103Y, Granted publication day: on 02 14th, 2007, disclose a kind of leveling sensor; Chinese patent Granted publication number: CN201628557U, Granted publication day: on November 10th, 2010, disclose a kind of damping unit of leveling sensor, but in prior art, disclosed leveling sensor is not but improved to above-mentioned existing weak point.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art part, and a kind of sensed position switchgear is provided, and this sensed position switchgear can be so that leveling sensor can not be restricted when measuring.
To achieve these goals, the utility model adopts with technical scheme:
A kind of sensed position switchgear, described sensed position switchgear comprises fixed cover, left cover and right cover, described left cover and right cover is fixed at respectively left end and the right-hand member of fixed cover, be fixed with and tighten joint at the bottom righthand side of described fixed cover, in described lower end of tightening joint, be fixed with flexible pipe.A kind of sensed position switchgear that the utility model proposes, it is arranged on leveling sensor, utilize contiguous block and pressing plate on leveling sensor to adjust and determine the gap between sensed position switchgear and frame bars assembly, again according to scope of work and the common road conditions of frame bars assembly, the installation site of this sensed position switchgear of the standard of special road conditions, then be fixed, can make like this measurement of leveling sensor unrestricted, if special road conditions occur, this sensed position switchgear will be responded in time and communication is arrived to operation bench, provide support to operating personnel's Job Operations.
As preferably, described flexible pipe is nylon hose.
As preferably, in the upper end of described fixed cover, be provided with transparent window film.
As preferably, described transparent window film adopts pmma material to make.
Compared with prior art, the utlity model has following beneficial effect: simple in structure, simple for production, by the sensed position switchgear is set on the column of leveling sensor, can be so that the unrestricted and special road conditions of the measurement of leveling sensor judge that the contradiction of can not and deposit is resolved, and has improved the measuring accuracy of large-scale maintenance machinery operating efficiency and sensor.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure, 1-left cover, 2-fixed cover, 3-transparent window film, 4-right cover, 5-tighten joint, 6-flexible pipe, 7-large leveling sensor.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model will be further described.
A kind of sensed position switchgear as shown in Figure 1, it is characterized in that: described sensed position switchgear comprises fixed cover 2, left cover 1 and right cover 4, described left cover 1 and right cover 4 are fixed at respectively left end and the right-hand member of fixed cover 2, be fixed with and tighten joint 5 at the bottom righthand side of described fixed cover 2, in described lower end of tightening joint 5, be fixed with flexible pipe 6.Be provided with transparent window film 3 in the upper end of described fixed cover 2.Large leveling sensor 7 is mounted in fixed cover 2 of the present utility model.
Preferably, described flexible pipe 6 is nylon hose; Preferably, described transparent window film 3 adopts pmma material to make.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, on embodiment and range of application, all will change, this description should not be construed as restriction of the present utility model.
