Abstract
The utility model discloses an elevator balance coefficient measurement instrument which comprises a position sensor (1), a current sensor (2), an emitter (3), a receiver (4) and a main controller (5). The position sensor (1) and the emitter (3) are arranged on the top of an elevator lift car, and the current sensor (2) is arranged on an elevator main circuit. The receiver (4) and the main controller (5) are arranged in a machine room. The current sensor (2) is connected with the main controller (5). The elevator balance coefficient measurement instrument automatically detects the position of an elevator lift car when the elevator lift car is in the same horizontal plane with a counterweight, automatically contacts the current sensor to record current values and automatically calculates out the balance coefficient, completely eliminates effect of human factors on accuracy of obtained balance coefficient values, and is more scientific and rigorous in detection method, and more accurate in detection result.
Description
Technical field
The utility model relates to survey meter, is specifically related to a kind of elevator balance coefficient measurer.
Background technology
" elevator supervision and inspection and periodical survey rule-traction and forcibly driving elevator " requires the equilibrium factor of elevator is 0.4-0.5, the method of inspection is: car carries respectively 30%, 40%, 45%, 50%, 60% rated load and moves up and down along omnidistance straight, when car with read the corresponding current value when focusing on same level, draw up curve and descending curve according to this value, the point of crossing of two curves is equilibrium factors.
For a long time, the inspector determines car and the method that focuses on same level generally had two kinds when measuring equilibrium factor at the scene, and a kind of is to make marks at hoist ropes, and another kind is according to the aobvious guestimate of layer.Because measured error can be larger when people's capability of reaction, first method were used for the low speed ladder, be used for the high speed ladder and then can't read at all.Second method has larger error equally.The error amount of above-mentioned two kinds of methods is directly proportional with the command speed of elevator, during the bound that requires near " rule " when the equilibrium factor of elevator reality (namely 0.4 and 0.5), such error might cause the inspector that the assay of oneself is thrown doubt upon, when with suspicion to recording process or numerical value, will again try again or more times, strengthen the labour intensity of check and installation personnel.Based on same reason, obtaining car and to after focusing on same level information, reading current value link also can produce error, the artificial up curve of drafting and descending curve acquisition point of crossing link also can produce error, these errors are enough to affect the accurate of conclusion, when the equilibrium factor of elevator reality during near bound, even the conclusion that may cause the inspector to do to make mistake.
Summary of the invention
The purpose of this utility model is: a kind of elevator balance coefficient measurer is provided, when car with when focusing on same level, automatically measure and record current value this moment, automatically draw up curve and descending curve, thoroughly break away from human element to obtaining the impact of equilibrium factor numerical value accuracy.
Technical solution of the present utility model is: this survey meter comprises position transduser, current sensor, projector, receptor and primary controller, position transduser, projector are installed in elevator car top, current sensor is installed on the elevator major loop, receptor, primary controller are installed in the machine room, and current sensor connects primary controller.
During detection, car carries respectively different load and moves up and down along omnidistance straight, the position transduser that is arranged on elevator car top detects operating car and when focusing on same level, the signal that detects is launched with wireless mode by projector, be arranged on receptor in the machine room and receive the current sensor that triggers behind the signal on the elevator major loop, read and preserve the current value of this moment, primary controller carries out curve fitting and computing drafting equilibrium factor diagram of curves according to the current value of different loads again, show with data, figure, determine thus the equilibrium factor of this elevator.
The utility model detects car and position when focusing on same level automatically, automatic trigger current sensor record current value, and automatically calculate equilibrium factor, thoroughly broken away from human element to obtaining the impact of equilibrium factor numerical value accuracy, make more science, rigorous of measuring means, assay is more accurate.
Description of drawings
Fig. 1 is functional block diagram of the present utility model.
Among the figure: 1 position transduser, 2 current sensors, 3 projectors, 4 receptors, 5 primary controllers.
The specific embodiment
As shown in Figure 1, this survey meter comprises position transduser 1, current sensor 2, projector 3, receptor 4 and primary controller 5, position transduser 1, projector 3 are installed in elevator car top, current sensor 2 is installed on the elevator major loop, receptor 4, primary controller 5 are installed in the machine room, and current sensor 2 connects primary controller 5.
During detection, car carries respectively different load and moves up and down along omnidistance straight, the position transduser 1 that is arranged on elevator car top detects operating car and when focusing on same level, the signal that detects is launched with wireless mode by projector 3, be arranged on receptor 4 in the machine room and receive the current sensor 2 that triggers behind the signal on the elevator major loop, read and preserve the current value of this moment, primary controller 5 carries out curve fitting and computing drafting equilibrium factor diagram of curves according to the current value of different loads again, with data, figure shows, determines thus the equilibrium factor of this elevator.
