Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.
The frame body part of the attached lifting scaffold comprises a plurality of vertical main frames which are arranged side by side and a horizontal supporting truss which is connected with the plurality of vertical main frames, the frame body can be lifted along a guide rail which is arranged vertically under the drive of an electric hoist and is supported by the top support of a wall-attached support which is fixed on the building frame after moving in place, and the existing monitoring system for monitoring the stress state of the frame body loses the monitoring function due to unloading. However, in the using process of the frame body, deformation or displacement may be generated due to overload of stacked materials, improper operation of workers and the like, so that the construction wind direction is brought. The horizontal support truss is used as an important connecting component for transmitting the vertical load of the frame body to the transverse load, and deformation or displacement generated by the frame body can be directly reflected on the horizontal support truss.
Based on this, the present utility model proposes a horizontal support truss 10, referring to fig. 1-2, the horizontal support truss 10 includes a main body formed by a plurality of truss units 11 connected in sequence, and a monitoring assembly, the truss units 11 generally adopt standard sections of a half-meter-shaped frame structure, including an upper cross bar and a lower cross bar, with high strength, and little deformation or damage is generated in part, and adjacent truss units 11 are generally connected and fixed by bolts and nuts, when the frame body is displaced or deformed, the inclination of one or a plurality of truss units 11 or the connection between adjacent truss units 11 is loose, which is reflected on the horizontal support truss 10. Therefore, the monitoring assembly comprises a first sensor 21, a second sensor 22 and a controller, wherein the first sensor 21 is arranged on the truss unit 11 and is used for monitoring whether the truss unit 11 where the first sensor 21 is positioned is horizontal, the second sensor 22 is arranged at the joint of two adjacent truss units 11 and is used for monitoring the transverse stress change between the two truss units, and the controller is in communication connection with the first sensor 21 and the second sensor 22 and can feed signals back to the user terminal in real time. It will be appreciated that the controller may be integrated with existing monitoring systems for monitoring the tension at the end of the electric block.
The first sensor 21 and the second sensor 22 are matched with each other, so that the blank that the current attached lifting scaffold is not monitored in the construction and use process is filled, and the attached lifting scaffold is safer in the use process. Specifically, if the indication of the second sensor 22 changes significantly, it is indicated that the connection between the two truss units 11 connected by the second sensor 22 is loose, and when the inspection is performed, the connection of the truss units 11 where the second sensor 22 with relatively large indication change is located can be focused on the inspection; if the indication of the first sensor 21 changes significantly, it is explained that the truss unit 11 tilts, and the reason why the truss unit 11 tilts is often because the stacking material on one side of the frame body exceeds the standard value, the lifting of the frame body on the two guide rails is not synchronous, and the like, and the two aspects can be examined with emphasis. It will be appreciated that the indication of the second sensor 22 will also change to some extent when the truss unit 11 is tilted, that is, it may be relatively obvious that only the second sensor 22 or both the first sensor 21 and the second sensor 22 will obviously determine the cause of deformation or displacement of the horizontal lattice 10 according to the indication change, so that it is convenient for the field personnel to quickly troubleshoot.
In order to warn the site personnel including but not limited to supervision, constructors and the like, the monitoring assembly further comprises an audible and visual alarm which is in communication connection with the controller, and when the numerical value monitored by the first sensor 21 or the second sensor 22 deviates from a preset value, the audible and visual alarm sends out an alarm signal so as to warn the site personnel to timely check the condition of the frame body.
The first sensor 21 may be an inclination sensor that can directly measure the inclination of the truss unit 11 in which it is located. In general, the place where the deformation of the transverse load of the frame body is the largest is the middle part of the maximum span of the frame body, that is, the truss unit 11 where the middle part of the main body is located is most obviously inclined, so the first sensor 21 is arranged on the truss unit 11 located in the middle part of the main body, and at this time, the data change obtained by monitoring by the first sensor 21 is most obvious.
The first sensor 21 may also be a laser ranging sensor, in practical use, a strip-shaped positioning block may be disposed on the building frame, the time taken for the laser emitted by the laser ranging sensor to irradiate on the positioning block and then reflect back to the laser ranging sensor to be received is t, along with the inclination of the truss unit 11, the laser emitted by the laser ranging sensor does not irradiate on the positioning block any more, but irradiates at the gap of the building frame or the building frame, at this time, the transmission path length of the laser becomes longer, the time interval for the laser ranging sensor to receive the reflected laser increases, that is, the preset value of the laser ranging sensor may be set to t, and when the time taken for the laser ranging sensor to receive the reflected laser is greater than t, it is indicated that the truss unit 11 has been inclined to a degree that the potential safety hazard is easy to occur.
All be provided with laser rangefinder sensor on a plurality of truss units 11, the degree of accuracy that detects not only can be improved in the setting of a plurality of laser rangefinder sensors, can learn the deformation condition of main part at a plurality of measuring points moreover, can effectively monitor local deflection and deformation.
Whether it is an inclination sensor or a laser ranging sensor, may be disposed in the mounting hole on the upper rail or the lower rail constituting the truss unit 11, avoiding damage to the first sensor 21 during use of the frame. Of course, it is understood that the tilt sensor and the laser ranging sensor may be used simultaneously to improve the accuracy of monitoring.
The second sensor 22 may then be a tension sensor or a pressure sensor.
Based on the above-mentioned horizontal support truss 10, one embodiment of the present utility model further provides an attached lifting scaffold, where the horizontal support truss 10 is installed at the bottom of the vertical main frame, specifically, on both inner and outer sides of the first layer of the vertical main frame, so that the horizontal support truss 10 is integrated with the vertical main frame. By monitoring the horizontal support truss 10, the state of the attached lifting scaffold can be monitored in real time, and the construction safety is further improved.
It is to be understood that the above examples of the present utility model are provided for clarity of illustration only and are not limiting of the embodiments of the present utility model. Various obvious changes, rearrangements and substitutions can be made by those skilled in the art without departing from the scope of the utility model. It is not necessary here nor is it exhaustive of all embodiments. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the utility model are desired to be protected by the following claims.
