Embodiment 1

[0043] A rapid tester for the strength of an escalator apron, comprising:

[0044] Such as figure 1 , 2 As shown, the detector body 1, the quick-adjustment mechanism 3 and the booster screw 2 that display the booster data, the booster screw 2 is coaxial and connected to the detector body 1 in rotation, and the rotation of the booster screw 2 relative to the quick-adjustment mechanism 3 plays a similar role. The effect of the screw slider makes the detector expand and contract and abut against the apron boards of the escalator. The middle sleeve of the booster screw 2 has a hexagonal head 18 with radially arranged booster holes 19 on the hexagonal head 18 . The hexagonal head 18 can go to rotate the booster screw 2 by a wrench to realize booster, and the plate bar is inserted into the booster hole 19 to rotate the booster screw 2 . The end of the detector body 1 away from the booster screw 2 has a support foot 15 ; the end of the adjustable support rod 14 away from the quick...

Embodiment 2

[0053] The difference between this embodiment and embodiment 1 is:

[0054] The shape of the guide hole 6 is different:

[0055] Such as Figure 8 As shown, the cross-sectional shape of the guide hole 6 includes an isosceles trapezoid with a large top and a small bottom, a first sector and a second sector, and the two ends of the first sector and the second sector are respectively arranged on the two bases of the isosceles trapezoid On the two corresponding end points, the half thread 5 is on the arc of the first sector with a smaller diameter, and the stroke of the quick adjustment block 4 in the cavity is shorter than the stroke of the booster screw 2 in the guide hole 6 . For a better description, taking the quick-adjustment block 4 as a reference frame, the booster screw 2 moves up and down relative to the quick-adjustment block 4 . The stroke difference between the quick adjustment block 4 and the booster screw 2 makes the outer edge of the booster screw 2 not reach the...

Abstract

The invention discloses a rapid detector for strength of an escalator skirt panel, and aims to overcome the defects that strength detection equipment for applying force to a threaded screw structure needs to be shortened in length when being put in and taken out before and after detection, and the length of the equipment is changed slowly due to difficult rotation of a screw rod due to space limitation. The rapid detector comprises: a detector body and a rotatably connected force application screw rod, wherein the force application screw rod rotates to enable the detector to stretch out and draw back and abut between skirt panels of an escalator; and a quick adjusting mechanism provided with a guide hole, wherein the force application screw rod is inserted into the guide hole, a moving gap is formed between the force application screw rod and the guide hole, a plurality of half threads corresponding to the force application screw rod are arranged at one end of the inner wall of the guide hole, the quick adjusting mechanism enables the guide hole to slide relative to the force application screw rod to switch the state of the quick adjusting mechanism, and after being placed in a detection position, the quick adjusting mechanism can be rapidly unfolded to approach a detection critical position and then recover to a rotating extension mode, so that the detection efficiency is improved, and the physical burden of detection personnel is saved.

Description

technical field [0001] The invention relates to an escalator detection device, more specifically, it relates to a rapid detection instrument for the strength of the escalator apron board. Background technique [0002] Escalators have been widely used in various public places as an important means of transportation, and with the increase in the number of escalators, safety accidents have also increased. Among them, one of the most common accidents is the pinching or pinching accident caused by insufficient rigidity of the apron board. [0003] According to the "Safety Specifications for the Manufacture and Installation of Escalators and Moving Walks": For the most unfavorable part of the apron board, apply a force of 1500N vertically on a square or circular area of ​​25cm2, and the depression should not be greater than 4mm, and should not This results in permanent deformation. The stiffness of the apron board is a very important index in the escalator, and it needs suitable...
