Description

Deformation monitoring device

Technical Field

The utility model relates to a deformation monitoring technology, especially the deformation monitoring technology of the big template of height on the building.

Background

In the conventional deformation monitoring of the high and large template, as disclosed in patent CN200920059002.2, a switch is disposed beside a monitored object for detecting the deformation of the high and large template, and when the deformation of the high and large template reaches a set value, the monitored object is driven to trigger the switch, so as to trigger the detection alarm system, so that people can take measures in time to prevent accidents such as collapse. Although the technology can monitor the deformation of the high and large template, the deformation of the high and large template is three-dimensional, but the technology can only realize the detection of two-dimensional deformation, and can only arrange a side of a monitored object and a switch in different dimensions to realize the detection of three-dimensional deformation, so the technology is inconvenient to use, and can only realize the detection of the specific deformation direction of some points of the three-dimensional space but cannot realize the detection of the deformation of any position and any direction of the three-dimensional space; patent CN201520656207.4 discloses a fix on monitored object laser irradiation on the target board, the removal through the facula on the target board judges the big template deformation condition, this kind of technique one can not touch alarm response device, two, multiple deformation can mutual interference, the actual conditions that leads to the removal of facula to correctly reflect the deformation (if subside with lead to laser upwards perk when taking place simultaneously, the deformation of subsiding will mutual interference with upwards perk, the deformation that makes the facula remove and deduce is not according with the actual conditions).

Disclosure of Invention

The invention aims to provide a deformation monitoring device which can realize the detection of the deformation of any position and any direction of a three-dimensional space and is convenient to use.

The deformation monitoring device is realized by the following steps that the deformation monitoring device comprises a support, a touch opener, a laser transmitter, a laser receiver and a warning device, wherein the touch opener, the laser transmitter, the laser receiver and the warning device are arranged on the support, the laser receiver controls the warning device to act, and the touch opener is a baffle with a hole in the middle.

When the device is used, the support is positioned on a high template to be detected, the laser transmitter is arranged on an object (such as a column) with a constant position, the laser receiver is arranged on another object (such as a column) with a constant position, laser emitted by the laser transmitter penetrates through the center of a hole in the middle of the baffle plate and irradiates on the laser receiver, and the size of the hole corresponds to the set allowable maximum deformation of the high template. When the high and large template deforms to drive the support to move, the baffle plate can move towards the laser position except for other movement along the laser path, when the deformation of the high and large template reaches or exceeds the maximum deformation, the laser can be shielded by the baffle plate, the laser can not be received by the laser receiver, the alarm is triggered through the laser receiver, or a control signal is sent to control the related equipment to start, so that accidents such as collapse are prevented, or an alarm is started, and related personnel are warned to take action to avoid risks or prevent accidents such as collapse.

Due to the adoption of the laser transmitter, the laser transmitter and the laser receiver can be far away from the touch opener, so that the fixation of the laser transmitter and the laser receiver is facilitated.

The front of the touch opener is provided with a sedimentation touch opener connected with the bracket, and the sedimentation touch opener is a stop block with a straight bottom surface. Because the safety allowance of downward settlement of the high and large templates is less than the allowable safety deformation amount in other directions, a special settlement touch trigger for sensing downward settlement of the high and large templates needs to be arranged and is positioned in front of the touch trigger, so that the laser beam shielded by the touch trigger can be blocked by the settlement touch trigger.

The trigger adopts an aperture regulator. The size of the hole in the middle of the diaphragm regulator serving as the baffle is adjusted by utilizing the function of adjusting the size of the lighting hole in the middle of the diaphragm regulator so as to meet the requirement that the size of the hole corresponds to the set allowable maximum deformation amount of the high and large template.

Here, in order to detect the deformation process and trend of the high and large template, a distance meter for measuring the distance from the support to a certain constant position (such as a laser receiver) is arranged on the support, and the deformation trend of the high and large template is analyzed by analyzing the change trend of the detected distance, so that the deformation reason can be analyzed and measures can be taken in time to solve the deformation problem of the high and large template.

Compared with the prior art, the utility model, have the detection, convenient to use's of the optional position that can realize three-dimensional space and arbitrary direction deformation advantage.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings and examples:

as shown in fig. 1, the utility model discloses a support 1, connect touching on support 1 through angular position regulator 2 and open ware 3, laser emitter 4, laser receiver 5, attention device 6, angular position regulator 2 can carry out the adjustment of three-dimensional position and angle to touching open ware 3, attention device 6 is the attention device including demonstration, warning, data collection, data analysis of PLC controlling means 601 control, laser receiver 5 passes through the action of PLC controlling means control attention device 6, it is the baffle 302 of middle part foraminiferous 301 to touch open ware 3. Laser beam D4 emitted by laser emitter 4 is angled towards trigger 3.

Preferably, the trigger 3 is an aperture adjuster. The aperture adjuster is a photographic device for adjusting the size of the aperture, that is, adjusting the size of the through hole in the middle of the aperture adjuster to adjust the size of light entering from the through hole. The inventor applies the method to the technology of the patent application, and the size of the aperture is adjusted to meet the requirement that the size of the aperture hole corresponds to the set allowable maximum deformation amount of the high and large template.

Preferably, the support 1 is provided with a distance meter 7 with an angular position adjustment support 701 for measuring the distance of the support 1 to a certain constant position (e.g. the laser receiver 5). The electric signal output end of the distance measuring instrument 7 is connected with the electric signal input end of the warning indicator 6.

Preferably, as shown in fig. 2, a set-down touch-and-open device 8 connected to the frame 1 by means of an angular position adjustment member 801 is provided in front of the touch-and-open device 3, the set-down touch-and-open device 8 being a stop whose bottom surface 802 is flat. Utilize the straight face of dog bottom surface, make the dog bottom surface parallel with the laser beam in the vertical direction, like this, no matter how big template warp and lead to the direction skew of support 1, as long as subside, the distance of so perpendicular descending subsides must be consistent with subside trigger 8 is the distance that the relative laser beam of bottom surface removed to guarantee to subside the accuracy of monitoring.

Preferably, a detection laser beam is provided to position the camera 9 within the hole 301. The touch initiator 3 can only shield the laser beam along with the movement of the support 1, the touch initiator 3 cannot detect the position where the laser beam is shielded, the laser receiver 5 only detects whether the laser beam exists, therefore, the touch initiator 3 or the laser receiver 5 cannot detect the position, the problem is solved through the camera 9, the camera 9 is used for observing the position where the touch initiator 3 blocks the laser beam, the direction and the position of the deformation of the high and large template can be analyzed, in addition, the trend of the deformation and the settlement of the high and large template can be judged through continuously observing the moving track of the laser beam in the hole, and enough time and space are reserved for making protective measures in advance.

As shown in fig. 3 and 4, the deformation monitoring method of the present invention is implemented by positioning the support 1 fixed with the trigger 3 of the deformation monitoring device on the high and large form a (shown in fig. 3 as a floor or a ceiling, and shown in fig. 4 as a wall) to be tested, arranging the laser transmitter 4 of the deformation monitoring device on the object B (such as a pillar) with a constant position, arranging the laser receiver 5 of the deformation monitoring device on the object C (such as a pillar) with a constant position, so that the laser beam D emitted by the laser transmitter 4 passes through the center of the hole 301 in the middle of the baffle 302 of the trigger 3 and irradiates on the laser receiver 5, the size of the hole 301 corresponds to the maximum allowable deformation of the set high and large form a, when the high and large form a deforms to drive the support to move, the baffle 302 moves toward the laser except for the other movements along the path of the laser beam D, when the deformation of the high and large template A reaches or exceeds the maximum deformation, the baffle plate 302 can shield the laser, so that the laser receiver 5 cannot receive the laser beam D, and the alarm 6 of the deformation monitoring device is triggered, or a control signal is sent to control the starting of related equipment to prevent accidents such as collapse, or an alarm is started to warn related personnel to take action to avoid risks or prevent accidents such as collapse.

The distance between the bottom surface of the sedimentation touch starter 8 of the deformation monitoring device and the laser corresponds to the set allowable maximum sedimentation amount of the high and large template A, at the moment, the bottom surface of the sedimentation touch starter 8 is parallel to the laser beam D, when the high and large template A is sedimentated to drive the support 1 to sink to a set value, the stop block serving as the sedimentation touch starter 8 can shield the laser beam D, so that the laser receiver 5 can not receive the laser beam D, and the alarm is triggered.

Two groups of deformation monitoring devices are arranged on a high and large template A, each group of deformation monitoring devices comprises a laser transmitter 4, a laser receiver 5 and a plurality of deformation monitoring units E consisting of a support 1, a touch opener 3, a distance meter 7 and a settlement touch opener 8, wherein a laser beam D of one group of deformation monitoring devices vertically penetrating through a hole 301 of the touch opener 3 of the group of deformation monitoring devices is vertical to a laser beam D of the other group of deformation monitoring devices vertically penetrating through a hole 301 of the touch opener 3 of the group of deformation monitoring devices. Because the deformation direction of the high and large template A and the laser beam D form an included angle, when the deformation direction of the high and large template A and the included angle of the laser beam D are 90 degrees, the distance of the baffle 302 forming the touch opener 3 moving to the laser beam D is consistent with the deformation of the high and large template A, along with the reduction of the included angle, the deformation of the baffle 302 forming the touch opener 3 and the laser beam D are increased, two groups of deformation monitoring devices are adopted, the laser beam D is perpendicular to each other, therefore, once the included angle of one group is smaller than 45 degrees, the included angle of the other group is larger than 45 degrees, and thus, the maximum difference value of the distance of the baffle 302 moving to the laser beam D and the deformation of the high and large template A is 2 degrees^1/2-1。

And a third group of deformation monitoring devices is arranged on the high and large template A, and the included angle between the laser beams D of the third group of deformation monitoring devices, which vertically penetrate through the holes 301 of the trigger 3 of the group of deformation monitoring devices, and the laser beams D of the other two groups of deformation monitoring devices, which vertically penetrate through the holes 301 of the trigger 3 of the group of deformation monitoring devices, is an acute angle. Thus, the maximum difference between the distance that shutter 302 of trigger 3 moves toward laser beam D and the amount of deformation of tall template a is smaller. The distance that baffle 302 of trigger 3 moves to laser beam D is closer to the amount of deformation of tall template a.
