Description
Technical Field
The utility model relates to an elevator test electromechanical device technical field, in particular to portable multi-functional elevator loading testing arrangement.
Background
The locking force of the elevator car door is an important technical requirement in an elevator car door system, and if the elevator car door is locked excessively, passengers can not manually and effectively open the car door to safely evacuate the elevator when the elevator is stopped accidentally in an unlocking area; if the locking force of the elevator car door is too small, the car door can be opened by passengers in a shivering manner in a non-unlocking area, so that the accident of stopping the elevator and closing people is caused, and unnecessary injuries are brought to people in the car.
In order to restrict the opening of the car door by the persons in the car, provision should be made in the modification list of the latest national standard GB 7588 and 2003 Elevator manufacturing and installation safety technical Specification I: a) when the lift car runs, the force for opening the lift car door is more than 50N; b) when the car is outside the area defined in 7.7.1, the car door can not be opened more than 50mm by applying 1000N of force at the door opening limiting device. The above clauses reflect two new requirements for the car door, one is the requirement for opening, namely, the lowest car door opening force is specified when the elevator runs dynamically; secondly, the requirement of limiting the opening, namely, when the elevator is outside the unlocking area, under the condition that 1000N of force is applied to the car door opening limiting device, the lowest car is specifiedThe door opening stroke. The technical specification for elevator manufacture and installation safety also specifies the mechanical strength of the elevator car wall, i.e. the force of 300N is uniformly distributed over 5cm2The car wall is vertically acted on any position of the car wall along the direction from the inside of the car to the outside of the car on the circular or square area of the car, and the car wall is characterized in that: a) no permanent deformation; b) the elastic deformation is not more than 15 mm. GB 16899 plus 2011 safety code for manufacturing and installing escalators and moving sidewalks stipulates that a 1500N force is vertically applied to 25cm at the most unfavorable part of the apron board2Should not be more than 4mm in its depression and should not cause permanent deformation as a result.

Because the elevator runs, the upper limit of the force gradually does not exceed 50N and needs to be finely adjusted manually, so that the test is difficult and the operation is dangerous; because sedan-chair door opening limiting device installs in the door plant top, both sides do not have the solid gap that can be used to support the angle steel installation, can not satisfy the detection requirement.
Patent (201620212867.8) discloses an elevator door opening force tester, adopts horizontal application of force mechanism, but the handheld test of inconvenient testing personnel to narrower door plant size, the length of its motor may exceed the length of door plant, leads to the unable correct loading of application of force board and crack clearance, influences the test result. The utility model discloses a do not mention the application of force that whether can be used to sedan-chair door opening door controlling means, the device probably interferes because the motor of transversely placing and pressure sensor and the annex of elevator door head, can not place correctly and can not accomplish the test.
The patent (201310153850.0) discloses a deformation testing device for elevator door car walls and escalator skirt boards, a servo motor is used as a force application device, rated thrust is applied to push a supporting device to move, the supporting device moves to enable the elevator door car walls or the escalator skirt boards to deform, a computing control system and a binding force sensing device control the force applied by the servo motor to the supporting device to be just the rated thrust, a displacement measuring device can measure the displacement of the supporting device, the displacement is equal to the deformation of the elevator door car walls or the escalator skirt boards, and the deformation of the elevator door car walls or the escalator skirt boards under the rated thrust can be accurately obtained through the device. However, the rotating shaft of the servo motor and the extension rod are in threaded connection, and the extension rod and the supporting plate at the tail end are also in threaded connection, so that when the motor rotates to apply force, the supporting plate can synchronously rotate around a shaft, and a dynamic friction force is generated on the contact surface of the supporting plate and the car wall or the skirt panel, so that test jitter is easily caused, and the stability and the precision of the test are influenced. Obviously, the static force application test is the best solution under the standard terms.
The three related patents all have single function, and if the elevator, the escalator and the moving sidewalk are to be inspected in the same place (such as a shopping mall, an office building and the like), the elevator, the escalator and the moving sidewalk are required to carry corresponding different devices, so that the carrying convenience is greatly reduced.
