Description

Elevator car and well wall distance measuring apparatu Technical Field The utility model relates to a special equipment detection device, in particular to a distance measuring instrument for an elevator car and a well wall. Background In the elevator inspection and detection process, the traditional method for manually measuring the distance between the elevator car and the wall of the well is time-consuming and labor-consuming, and has the problems that measurement data are inaccurate and incomplete, and the personnel of an inspector have the risks of elevator extrusion, shearing and the like. Some existing automatic measuring equipment has some defects, such as complex installation and deployment flow, easy influence of dust and strong light due to the adoption of a pure laser ranging scheme, and the like. The most obvious disadvantage is that the scheme adopted by most similar measuring equipment for measuring the distance between the elevator car and the wall of the hoistway is that the elevator car top is placed, so that the problem that the elevator car wall below the elevator car bottom layer station belongs to a measuring blind area because the elevator car top cannot reach the position of the elevator car bottom layer station when the measuring equipment is placed on the elevator car top is solved. Therefore, it is necessary to design a device for measuring the distance between the car and the hoistway wall without a blind measurement area. Disclosure of Invention In order to solve the technical problems, the utility model provides an elevator car and hoistway wall distance measuring instrument which can detect the hoistway wall and car distance below a bottom landing and has no measuring blind area. The elevator car and hoistway wall distance measuring instrument comprises a host machine and a vertical measuring module, wherein the vertical measuring module is arranged on the top surface of the elevator car and comprises a first shell and a first laser sensor arranged on the first shell, the first laser sensor is connected with the host machine through a cable, the elevator car and hoistway wall distance measuring instrument further comprises a horizontal measuring module, the horizontal measuring module comprises a second shell, a second laser sensor and an inclination sensor which are arranged on the second shell, the second shell is arranged below the elevator car through a mounting frame, and the second laser sensor and the inclination sensor are in wireless connection with the host machine through a wireless module. The elevator car and hoistway wall distance measuring instrument has the advantages that the elevator car and hoistway wall distance measuring instrument is provided with the vertical measuring module on the top surface of the elevator car, so that accurate measurement of the distance between the elevator car and the upper hoistway wall is achieved through the first laser sensor of the vertical measuring module, the horizontal measuring module is arranged below the elevator car through the mounting frame, the distance between the elevator car and the hoistway wall below the bottom floor station can be measured through the second laser sensor and the inclination sensor of the horizontal measuring module, and therefore non-blind area automatic detection of the distance between the hoistway wall and the elevator car is achieved. Furthermore, the elevator car and hoistway wall distance measuring instrument provided by the utility model is characterized in that the vertical measuring module further comprises an acceleration sensor, and the acceleration sensor is arranged in the first shell. The arrangement of the acceleration sensor increases the use measurement scene of the elevator car and the hoistway wall distance measuring instrument, and reduces the influence of dust in the hoistway and strong light in the glass hoistway on the first laser sensor. Furthermore, the distance measuring instrument for the elevator car and the hoistway wall is characterized in that a magnetic attraction array is arranged at the bottom of the first shell, the magnetic attraction array comprises a plurality of magnetic pieces, and the first shell is attracted to the top surface of the car through the magnetic attraction array. The arrangement of the magnetic attraction array facilitates the arrangement of the vertical measuring module by the detection personnel, so that the detection efficiency is improved. Furthermore, the elevator car and hoistway wall distance measuring instrument comprises the mounting frame, wherein the mounting frame comprises a metal connecting rod, the top of the metal connecting rod is connected with the bottom surface of the elevator car, the bottom end of the metal connecting rod is connected with a universal rod, one end of the universal rod is connected with the metal connecting rod through a universal joint, and the second shell is fixedly arranged at the front end of the
