Description

Technical Field

[0001] The utility model belongs to the technical field of inspection and measurement, in particular to a device for detecting the gap between an elevator counterweight and a car. Background Art

[0002] As an indispensable vertical transportation tool in modern buildings, the safety and reliability of elevators are of vital importance. The elevator car and counterweight system are key parts to ensure the normal operation of the elevator. The appropriate distance between the two is crucial to the balance, stability and safety of the elevator. Therefore, accurately measuring the distance between the elevator car and the counterweight is an important part of the elevator maintenance and inspection process.

[0003] Elevator regulations and standards require measuring the distance between the counterweight and the car. When measuring, people can only stand on the working platform on the top of the car. Due to limited space, it is not convenient to measure directly. In addition, the current calipers or other similar measuring tools cannot reach the distance between the car and the centering when measuring, which is very difficult for operators to operate and inconvenient to measure accurately. Therefore, a detection device that can easily detect the distance between the elevator counterweight and the car is proposed. Utility Model Content

[0004] In view of the above problems, the utility model provides an elevator counterweight and car gap detection device, which is used to solve the problem that during the detection of the car and the centering distance, the measuring tool is inconvenient to measure and operate due to limited space.

[0005] To achieve the above object, the technical solution adopted by the utility model is: an elevator counterweight and car gap detection device, comprising a first measuring claw assembly and a second measuring claw assembly which are mutually cross-hinged, the upper end of the second measuring claw assembly is hingedly provided with a scale, a cursor for indicating a position is slidably provided on the scale, and the cursor and the first measuring claw assembly are mutually hingedly provided;

[0006] The lower ends of the first measuring jaw assembly and the second measuring jaw assembly are provided with contact members for contacting the measured position;

[0007] A level is also provided on the ruler.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the first measuring claw assembly and the second measuring claw assembly arranged in a cross-hinged manner can be conveniently extended into the gap between the elevator car and the counterweight. When measuring, the distance of the gap can be directly read on the ruler, so that measurement can be performed in a confined space. By setting up a level, it is convenient to maintain levelness during measurement to ensure the accuracy of the measurement.

[0009] As a further improvement of the above solution, the ruler is provided with a guide bar for facilitating the reciprocating sliding of the cursor, and the end of the ruler is provided with a limiting platform for blocking and limiting the cursor.

[0010] As a further improvement of the above solution, the cursor includes an indicating portion and an extending portion, and the extending portion is provided with a locking knob for fixing the cursor and the scale to each other.

[0011] The technical effect of the above improvement is: the range of motion of the cursor can be limited by the setting of the limiting platform and kept within a specific measuring range. The locking knob is mainly used to facilitate locking the position between the cursor and the scale after measuring the reading, thereby facilitating reading.

[0012] As a further improvement of the above solution, the contact member includes a base plate which is rotatably arranged with the first measuring jaw assembly or the second measuring jaw assembly, a permanent magnet is arranged on the base plate, and a contact plate is also arranged on the surface of the base plate.

[0013] The technical effect of the above improvement is that the permanent magnet can facilitate magnetic adsorption between the two side walls of the side measurement when side measurement is performed, so as to facilitate automatic contact positioning.

[0014] As a further improvement of the above solution, the first measuring jaw assembly includes a first connecting rod, a handle and a second connecting rod. The first connecting rod and the cursor are hinged to each other, the handle is fixed on the first connecting rod, and the second connecting rod is detachably inserted into the handle.

[0015] As a further improvement of the above solution, a latch is provided between the second connecting rod and the handle for fixing the second connecting rod and the handle to each other.

[0016] The technical effect of the above improvement is: the second connecting rod and the handle are set to be detachable, mainly so that when the entire device is not in use, the first measuring claw assembly, the second measuring claw assembly and the ruler can be freely folded and stored together.
