Description
Technical Field
The invention relates to the field of elevators, in particular to an elevator guide rail deformation detection device.
Background
The elevator guide rail is an elevator component consisting of steel rails and connecting plates, and is divided into three forms, namely a T-shaped form, an L-shaped form and a hollow form, from the cross section shape. The guide rails of the elevator are generally fixedly connected to the wall of the hoistway through a guide rail bracket and a guide rail support, and the guide rails commonly used for the elevator are T-shaped guide rails. Because the guide rail is a guide shoe on the elevator car and a shuttle rail of the safety gear, the plane of the guide rail must be smooth without obvious uneven surfaces. The guide rail can play a role in guiding and can bear the impact force generated when the elevator car and the elevator are braked, the impact force generated when the safety tongs are emergently braked and the like.
At present, the detection of the elevator guide rail is mostly carried out by a laser device or the change of a moving wheel when the moving wheel passes through the surface of the guide rail. For example, patent document No. 202110952135.8, application No. 2.21.08.19 discloses an elevator guide rail straightening position detecting tool, which detects and reflects whether a guide rail is bent or not by rolling of a moving wheel on the surface of the guide rail and according to pressure changes of the moving wheel caused by undulation of the surface of the guide rail.
However, the detection of the guide rail is generally that the straightness detection is carried out before leaving the factory after production, the elevator guide rail is installed behind an elevator shaft, whether the installation is vertical or not is generally detected through a manual suspension wire and the like, but in the process of elevator transportation and installation, particularly operation, whether the guide rail is sunken or deformed or not is detected, automatic real-time detection equipment is lacked, and only periodic manual detection is carried out, so that the elevator guide rail is used as a shuttle rail of a car guide shoe and a safety gear, particularly a clamping object during emergency braking of the safety gear, and great safety risk is brought to the operation of an elevator. In addition, the existing detection equipment represented by the above patent is only used for detection after being produced by a manufacturer, and does not need to consider the damage, deformation and the like of the detection guide rail, so the detection coverage range of the detection equipment is narrow and is generally a straight line, and the position of the recess or the deformation is uncertain for the recess or the deformation and the like possibly caused in the process of transportation and installation of the guide rail in reality, particularly after the guide rail is used in an elevator shaft, and the coverage range of the existing detection equipment is narrow, so that the existing detection equipment cannot adapt to real-time detection in actual use. And above-mentioned patent still has some problems, for example through will remove the displacement change of wheel in perpendicular guide rail surface direction, convert pressure change into through the spring, when being detected by force sensitive sensor again, because the change on guide rail surface is usually at the millimeter level, and the sensitivity that converts to pressure when detecting requires higher to force sensitive sensor for equipment cost is higher, and in addition, the stiffness coefficient of spring receives the temperature influence can produce the change, causes the pressure of conversion inaccurate, influences actual testing result.

The above communication mode, power supply mode, and the like are all conventional common technical means, and do not belong to the content of the scheme claimed in the present application, and are not described herein again.
The sliding mechanism comprises a sliding groove 21, a sliding block 22 and a roller 25, the sliding groove 21 is arranged on the base 7, and the sliding block 22 is arranged in the sliding groove 21 in a sliding manner through the roller 25; the detection mechanism is arranged on the slide block 22; the driving mechanism is connected with the slide block 22 in a driving way. The sliding groove 21 is horizontally arranged, the notch 24 of the sliding groove 21 faces the guide rail 1, the roller 25 is rotatably arranged at the bottom of the sliding block 22, and the sliding block 22 and the roller 25 are movably arranged in the sliding groove 21. In reality, the sliding block 22 is prevented from shaking in the sliding groove 21 while the sliding block 22 slides in the sliding groove 21, and two sides and the top of the sliding block 22 are attached to the side wall of the sliding groove 21. In this embodiment, the driving mechanism is an electric push rod 23, the electric push rod 23 is disposed on the base 7, and a free telescopic end of the electric push rod 23 is connected to the sliding mechanism in a driving manner. The electric push rod 23 is fixed on the base 7, the free telescopic end of the electric push rod 23 is fixedly connected to the sliding block 22, and the sliding block 22 is driven and fixed to avoid the sliding block 22 from shaking in the direction perpendicular to the sliding groove 21. In this embodiment, the moving wheel 5 is disposed on the detecting column 4 through a bearing 9, that is, the moving wheel 5 is a universal wheel, so that the moving wheel 5 can adjust the direction according to the driving force. The detection block 3 is fixed on one side of the sliding block 22 through the notch 24, when the electric push rod 23 drives the sliding block 22 to move in the horizontal direction, the detection mechanism is driven to move in the horizontal direction, the detection range of the moving wheel 5 of the detection mechanism is a vertical line range on the guide rail 1, and after the detection mechanism moves, the detection range of the moving wheel 5 of the detection mechanism is adjusted to be a vertical line range parallel to the vertical line range before adjustment. In reality, after the elevator runs to the bottom or the top of the elevator shaft, the position of the detection mechanism horizontally moves for a certain distance such as one centimeter relative to the guide rail 1 through the adjusting mechanism 2, then the elevator car is controlled to run, at the moment, the detection range of the detection mechanism in the up-and-down process of the elevator car is translated for a certain distance with the adjustment, as shown in fig. 8, the track of the detection mechanism moving on the guide rail is driven to be a running detection track 11 when the elevator normally runs up and down, and the detection range of the position of the detection mechanism horizontally moves for a certain distance relative to the guide rail 1 is an adjusting detection track 12 when the elevator is adjusted.

It should be noted that, when the detection mechanism is adjusted, only the horizontal displacement of the detection mechanism relative to the guide rail 1 is changed, but the horizontal relative position of the base 7 and the guide rail 1 is not changed, that is, the horizontal relative distance between the third group of detection mechanisms 6 for detecting the end surface of the guide rail 1 and the guide rail 1 is not changed, and the detection of the third group of detection mechanisms 6 is not affected. If the fastening elements of the guide rail 1, such as bolts or brackets, become loose, the guide rail 1 will have a certain inclination or displacement change in the direction of the elevator car, which change can be reflected on the basis of the detection information from the third group of detection means 6.
Preferably, a limiting plate is arranged on the base 7 corresponding to the sliding block 22, and a limiting switch is arranged on the limiting plate corresponding to the sliding block 22.

In this embodiment, the limiting plate is actually the inner wall of the end of the chute 21, and when the limiting switch is triggered, the limiting switch is forced to stop adjusting, so as to avoid the problem of the program of the electric push rod 23 and cause the adjusting range to be too large, and the limiting switch belongs to a redundant configuration, so as to fully guarantee the adjusting safety.
