Problems solved by technology

[0004] 1. For different models of models, it is necessary to make limit marks with different scale requirements. On the one hand, it is a waste of paper, on the other hand, it increases the workload of the staff and increases the error;
[0005] 2. The pasted paper signs are easily damaged with the prolongation of use time and human damage, resulting in unclear scales or fading of bright warning colors, reducing the accuracy of safety maintenance work and increasing the risk of maintenance

Embodiment Construction

[0018] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0019] A trolley position limit identification board, such as figure 1 As shown, it includes an insulating plate body 4, a rectangular scale plate 1, and a limit mark 8. The insulating plate body is a rectangular plate, and a U-shaped groove is opened on one side of the rectangular plate, and two rectangular scale plates are installed in parallel on both sides of the U-shaped groove, and the rectangular scale plate is fixed on the The upper surface of the insulating plate body; two longitudinal slide rails 3 are correspondingly opened on the two rectangular scale plates, and scale lines 6 are evenly and horizontally arranged on the sides parallel to the slide rails; Set two limit marks, each limit mark is set in the slide rail through a sli...

Abstract

The invention relates to a trolley position limiting and identifying plate. The trolley position limiting and identifying plate comprises an insulation board, rectangular scale plates and limiting identification, and through the arrangement of sliding limiting identification, the identification can be arranged according to different vehicle models and safety specifications. Paper limiting identification is not needed to be made repeatedly or massively, paper is saved, the trolley position limiting and identifying plate is economical and environment-friendly, working load of workers is reduced, and work efficiency is improved. Meanwhile, the situation that the attached paper identification is damaged due to prolongation of service life and artificial destruction, so that scales are unclear or bright caution color fades is avoided, thereby maintenance safety is guaranteed, maintenance danger is lowered, and the trolley position limiting and identifying plate is suitable for being extensively used and popularized in the electric power industry.

Description

technical field [0001] The invention belongs to the field of electric power safety, and relates to a warning device for safety maintenance, in particular to a trolley position limit sign board. Background technique [0002] In electric power engineering, some current 35kV switch trolleys, when the trolley needs to be pushed into the operating position, usually use the experience of the operation and maintenance personnel to adjust whether the contacts of the trolley are firmly in contact. If the position of the trolley is not suitable, the switch cannot operate normally. Affecting the maintenance schedule may also cause danger. [0003] The existing practice is to install a limit mark at the position of the rocker arm of the trolley, so that the operation can be standardized and normalized. However, the existing limit marks are artificially made paper sign boards, which are usually pasted on the side of the stroke groove of the rocker arm of the 35kV switch trolley, but the...
