Detailed Description
The present invention will be further explained with reference to the following examples.
As shown in fig. 1-4, the elevator landing door clearance inspection clamp comprises a display screen 3, a stoppable jaw 1, a clamp handle 4, a pressure sensor 6, a spring 5 and a clamp body 2; the stoppable jaw is composed of two thin steel plates, and the outer sides of the two thin steel plates are fixedly connected with a clamp handle respectively; the front of the pliers body 2 is provided with a measuring scale 7, two sliding grooves are formed in the pliers body 2 along the length direction of the measuring scale 7, the lower portion of a stoppable jaw moves through the sliding grooves, a through hole is formed in the middle of the pliers body 2, the stoppable jaw and the pliers handle after being fixedly connected penetrate through the through hole, two springs are respectively placed in the through hole, one end of each spring is connected with the pliers handle, the other end of each spring is provided with a pressure sensor, and the output of each pressure sensor is connected with a display screen. The stoppable jaw 1 is welded with the jaw handle 4, the spring 5 is connected with the jaw handle 4 and the pressure sensor 6 through welding, and the pressure sensor 6 is adhered to two ends of the chute through a strong glue and is directly welded with the spring for measuring the stress of the stoppable jaw. The display screen 3 is adhered to the two ends of the front surface of the clamp body 2 through strong glue, and the data transmission line of the display screen is connected with the pressure sensor through the inside of the clamp body 2 to display the pressure measured by the pressure sensor in real time.
The stoppable jaw 1 is composed of two thin steel plates, the two plates are attached when the stoppable jaw is not used, and the attaching surface is opposite to the 0 scale of the measuring scale 7. The scales on the two sides of the measuring scale 7 reach 40mm, and the measuring scale can adapt to the inspection of the opening size of a landing door with the width of 0 mm-80 mm. When the stoppable jaw 1 is used, the stoppable jaw 1 is stuffed into an elevator landing door, the opening of the clamp handle 4 can drive the stoppable jaw 1 to move towards two sides, and the size of the landing door opening can be obtained by comparing with the measuring scale 7. The size of the movement of the stoppable jaw 1 is converted into a pressure value by the amount of deformation of the spring.
The working principle of the device is as follows: during inspection, the part of the stoppable jaw is plugged into the gap of the landing door, the clamp handle is held to apply certain horizontal pressure to two sides, the numerical value of the display screen is observed, when the numerical value displayed by the display screen reaches a required value (150N), the reading on the measuring scale at the moment is read, and whether the gap of the landing door meets the inspection requirement or not is verified. In addition, the elevator landing door clearance inspection clamp can be perfectly suitable for various types of landing doors, and not only can the position be conveniently moved, but also the opening size can be conveniently inspected.
In this specification, the directions of the upper, lower, left, right, front and rear are based on the direction facing the paper surface.
