Problems solved by technology

When the car is at the leveling position of the lower end station, the distance from the top surface of the counterweight guide shoe (the plastic oil cup can be ignored) to the end of the counterweight guide rail and the buffer distance must be measured with a tape measure. The corresponding measurement values ​​of each person are different, and the cumulative error is large At the same time, the total compression stroke in the above measurement method includes the compression stroke of the buffer. According to the requirements of the relevant work instructions, the compression stroke of the nonlinear buffer is only assumed to be 90% of the compressible height, and the compression height also needs traditional measurement such as a tape measure Instrument measurement, and the compression stroke of many nonlinear buffers on site is not exactly 90% of the compressible height, which will greatly reduce the

Example Embodiment

[0046] Example 1

[0047] like Figure 1-7 As shown, an elevator counterweight guide rail guidance stroke measuring device based on sensor technology in this implementation is used to measure the guidance stroke of the elevator counterweight guide rail 2, including a support 6, a walking wheel 7, a positioning component, a measuring robot 4 and a remote Jogbox.

[0048] read on figure 2 , the support 6 is a bearing support, which covers the guide surface of the elevator guide rail. There can be one traveling wheel 7, or a plurality of parallel ones. In this embodiment, the traveling wheels 7 are two arranged up and down, and each traveling wheel 7 is fixed on the support 6 through a mandrel 61 rotation. And the running wheel 7 is arranged on the two sides facing the guide surface on the elevator counterweight guide rail 2 . Driven by the driving device, the driving device is a driving motor 9 in the present embodiment, and the driving motor 9 is connected on the mandrel 6...

Example Embodiment

[0058] Example 2

[0059] The elevator guide rail guiding stroke measuring device provided by this embodiment adds a guide mechanism on the basis of embodiment 1, and the guide mechanism includes a guide rod 30, a guide frame 31, and a support portion 32; On the shell; the guide rod 30 is fixed laterally at one end of the support portion 32, and the other end is connected to the guide frame 31, wherein the guide rod 30 is connected with the body 20 and the support 6 as an integral structure.

[0060] The guide mechanism connects the body 20 of the fixed part and the support 6 as a whole. When the measuring device runs on the guide rail, the guide bar 30 fixes the entire support 6 laterally. When the traveling wheels 7 move, the whole device is more stable. The side of the robot 4 is protected, which is beneficial to prevent the lateral deviation of the measuring robot 4 .

Example Embodiment

[0061] Example 3

[0062] The elevator counterweight guide rail guidance stroke measuring device provided in this embodiment has two displacement sensors 26 and two pressure sensors 25 added on the basis of embodiment 1, and the displacement sensors 26 are correspondingly installed on the body 20, and its signal path Connected to the microprocessor 48 , the pressure sensor 25 is correspondingly located at one end of the elastic member 23 , and its signal is sent to the microprocessor 48 . The distance deviation of the data transmitted by the two displacement sensors 26 shows whether the traveling wheel 7 is walking on the middle straight line of the counterweight guide rail 2, and the pressure signal of the pressure sensor 25 also reflects the force situation of the two positioning plates 21, which can be analyzed according to the values The running state of the walking wheel 7 is convenient for surveyors to observe and correct adjustments.

[0063] As on the basis of the above...

Abstract

The invention discloses an elevator counterweight guide rail guidance stroke measurement device based on the sensor technology. The device comprises a measurement robot and a remote control box. The distance between the machine body of the measurement robot and a guidance surface of a guide rail is measured in real time through a Hall sensor on the robot. The distance between the top of the counterweight guide rail and an elevator counterweight side oil cup is measured through a laser distance sensor. Then the guide rail guidance stroke of when a buffer is completely compressed by an elevatoris measured. According to the elevator counterweight guide rail guidance stroke measurement device based on the sensor technology, a method is high in measurement accuracy and quick in measurement, the problem that it is difficult to measure the guide rail guidance stroke is solved, the measurement accuracy of the guide rail guidance stroke is greatly improved, the checking science level of a checking mechanism is improved as well, and powerful technology support is provided for guaranteeing elevator operation security.
