Description

The elevator timing counter

The utility model relates to a kind of counting machine.

In the prior art, in order to observe the work-hours of elevator, an elevator counting machine need be set, determine the time of run of elevator according to the numeral of counting machine, but the time of run of elevator should obtain according to the logout time of reality, and the number of run of elevator is an indirect calculated amount.

The purpose of this utility model is to provide a kind of elevator timing counter that can carry out timing and two kinds of meterings of counting to elevator.

The technical solution of the utility model is: it comprises timing number wheel and count number wheel, and the wheel shaft of described count number wheel is provided with counting gear, and take on the tooth that is placed on this counting gear an end of counting driving lever, and the other end below of counting driving lever is provided with electromagnet; The end gear of described timing number wheel and transmission gear engagement, transmission gear is through one group of reducing gear and synchronous dynamo engagement.

The utility model compared with prior art has following advantage:

(1). the pulse that timing number wheel relies on crystal oscillator to produce is rotated stepping motor, drives timing number wheel by reducing gear and rotates, and can accurately calculate the time of run of elevator.

(2). count number wheel and timing number wheel are installed on the support, and service personnel can be observed easily.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is structure master's cutaway view of the present utility model;

Accompanying drawing 2 is a birds-eye view of the present utility model;

Accompanying drawing 3 is the left view after case of the present utility model is opened;

Accompanying drawing 4 is the front view of the speed reduction gearing of timing number wheel of the present utility model; Wherein:

[1]. transmission gear; [2]. timing number wheel; [3]. case; [4]. the counting driving lever; [5]. support; [6]. circuit card; [7]. base; [8]. counting gear; [9]. electromagnet; [10]. the count number wheel; [11]. connection terminal; [12]. buckle; [13]. minute wheel; [14]. second wheel; [15]. synchronous dynamo; [16]. frequency divider.

Embodiment: referring to accompanying drawing 2, the utility model comprises timing number wheel [2] and count number wheel [10], described two groups of numbers wheel is the decimal digit wheel, the wheel shaft of described count number wheel [10] is provided with counting gear [8], can drive counting gear after the tooth of this counting gear [8] is struck and rotates and single-frame rotate.Take on the tooth that is placed on this counting gear [8] one end of counting driving lever [4], the other end below of counting driving lever [4] is provided with electromagnet [9], when the every operation of elevator once, electromagnet [9] just, attract counting driving lever [4] to move down, stir counting gear [8] and rotate a tooth, count number wheel [10] makes to add a counting; The end gear of described timing number wheel [2] and transmission gear [1] engagement, the rotation of end gear can drive timing number wheel [10] and make to add a counting.Referring to accompanying drawing 4, transmission gear [1] is through one group of reducing gear (for example minute wheel [13] and second wheel [14]) and synchronous dynamo [15] engagement.The control by pulses that this synchronous dynamo [15] is sent by frequency divider [16], and frequency divider [16] carries out frequency division to the clock pulse that crystal oscillator sends.Referring to accompanying drawing 1, described timing number wheel [2] and count number wheel [10] all are arranged on the support [5], and this support [5] is fixed on the base [7].Described support [5] outside is covered with case [3], and case [3] is connected with the bayonet socket of base [7] by buckle [12].
