Description

Technical Field

[0001] The invention relates to the field of gantry crane accessories, in particular to a protective cover device used for packaging a deformation monitoring device. Background Art

[0002] A gantry crane (also known as a gantry crane) is a bridge-type crane whose bridge is supported on the ground track by legs on both sides. Structurally, it consists of a gantry, a trolley running mechanism, a lifting trolley, and an electrical part. Conventional gantry cranes, such as the Chinese invention patent with application number 2017109157295, disclose a gantry crane. When the crane lifts heavy objects, the gantry consisting of its main beam and soft and hard support legs is a direct load-bearing component and will undergo a certain degree of bending deformation. When the bending is too large, it will cause cracks or deformation in the main beam, which not only poses a serious safety hazard, but is also not conducive to the normal operation of the equipment. For this reason, deformation monitoring of the gantry is very necessary.

[0003] The applicant proposed a patch monitoring technical solution, in which the bottom of the patch body is bonded to the monitored object as a whole, and a monitoring device is provided on the top. Due to the large length of the patch, the patch is usually rolled up for easy transportation and storage. When it is installed, the rolled shape changes to a flat shape, and the temperature of the working environment changes later, which leads to a certain probability of deformation of the patch body, thereby affecting the alignment accuracy of the laser transmitter and laser receiver. Summary of the invention

[0004] The present invention provides a protective cover device for packaging a deformation monitoring device, so as to significantly reduce the probability of deformation of a laser monitoring patch due to environmental changes.

[0005] The present invention adopts the following technical solution:

[0006] A protective cover device for packaging a deformation monitoring device comprises a patch body, the bottom surface of which is provided with an adhesive layer for bonding to a monitored object. The top surface of the patch body is provided with a protective cover, which is a protective cover made of a hard material; preferably, the protective cover is a protective cover made of acrylic material. The bottom edge of the protective cover is sealed and connected to the top surface of the patch body as a whole, and the laser transmitter of the monitoring device and the laser receiver are arranged in a closed area surrounded by the protective cover and the top surface of the patch body.

[0007] As a further improvement, the connection between the protective cover and the patch body is preferably the following two: first, a rubber sealing gasket is provided between the bottom edge of the protective cover and the top surface of the patch body, and the bottom edge of the protective cover and the peripheral edge of the patch body are clamped and fixed by a U-shaped buckle. Second, the bottom edge of the protective cover and the patch body are fixedly bonded as a whole by an adhesive layer.

[0008] In a further improvement, a shaping sheet is embedded in the patch body, and the shaping sheet is a shaping sheet made of memory metal material; the shaping sheet is in a flat strip shape, and the width direction of the shaping sheet is consistent with the width direction of the patch body. The thickness of the shaping sheet is 0.1 to 0.35 times the thickness of the patch body, and preferably the thickness of the shaping sheet is 0.185 times the thickness of the patch body. The two ends of the patch body are respectively a laser end and a receiving end, and the shaping sheet extends from the laser end to the receiving end. The laser end is provided with a first mounting hole, and the laser transmitter is fixedly mounted in the first mounting hole. The receiving end is provided with a second mounting hole, and the laser receiver is fixedly mounted in the second mounting hole. The first mounting hole and the second mounting hole extend into the shaping sheet or penetrate the shaping sheet respectively. The cross-sections of the first mounting hole and the second mounting hole are both non-circular structures, and the laser transmitter and the laser receiver are plugged and installed in accordance with the corresponding mounting holes. The laser receiver is arranged on a straight path of the laser transmitter along the length direction of the patch body.

[0009] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: the patch body placed on the monitored body is fixedly connected to the hard protective cover, which can play a good fixing effect on the periphery of the patch body, effectively improving the rigidity of the patch body, so that it can effectively reduce the deformation probability of the patch body during the morphological changes from the storage state to the installation state and the later complex working environment, which is beneficial to the stable operation of the deformation monitoring device.

The top surface of the patch body 1 is provided with a protective cover 16, and the protective cover 16 is a protective cover 16 made of a hard material; preferably, the protective cover 16 is a protective cover made of acrylic material. The bottom edge of the protective cover 16 is sealed and connected to the top surface of the patch body as a whole, and the laser transmitter 12 and the laser receiver 13 are arranged in a closed area surrounded by the protective cover 16 and the top surface of the patch body 1.

[0018] The connection between the protective cover and the patch body is preferably the following two: first, refer to Figure 4 A rubber sealing gasket 161 is provided between the bottom edge of the protective cover 16 and the top surface of the patch body 1. The bottom edge of the protective cover 16 and the periphery of the patch body 1 are clamped and fixed by a U-shaped buckle structure formed by an L-shaped buckle 162 and the patch body. Figure 1 The bottom edge of the protective cover 16 is fixedly bonded to the patch body 1 through an adhesive layer.

[0019] The patch body 1 placed on the object to be monitored is fixedly connected to the hard protective cover 16, which can play a good fixing role on the periphery of the patch body 1, effectively improving the structural rigidity of the patch body 1, so that it can effectively reduce the deformation probability of the patch body 1 during the morphological changes from the storage state to the installation state and the later complex working environment, which is conducive to the stable operation of the deformation monitoring device. In addition, the configuration of the protective cover 16 can effectively reduce the influence of adverse factors such as dust, rain and fog in the external environment on the propagation of laser, and ensure the normal propagation of laser between the laser transmitter 12 and the laser receiver 13.

[0020] Reference Figure 6, a shaping sheet 10 is embedded in the patch body 1, and the shaping sheet 10 is in the shape of a flat long strip, and the width direction of the shaping sheet 10 is consistent with the width direction of the patch body 1. The two ends of the patch body 1 are respectively a laser end and a receiving end, and the shaping sheet 10 extends from the laser end to the receiving end. The laser end is provided with a first mounting hole 101, and the laser transmitter 12 is fixedly installed in the first mounting hole 101. The receiving end is provided with a second mounting hole 102, and the laser receiver 13 is fixedly installed in the second mounting hole 102. The cross-sections of the first mounting hole 101 and the second mounting hole 102 are both non-circular structures, and the laser transmitter 12 and the laser receiver 13 are installed in a matching and plug-in manner with the corresponding mounting holes. The laser receiver 13 is arranged on a straight path of the laser transmitter 12 along the length direction of the patch body 1. The first mounting hole 101 and the second mounting hole 102 extend into the shaping sheet 10 or penetrate the shaping sheet 10 respectively. The shaping sheet 10 is a shaping sheet 10 made of memory metal material; the thickness of the shaping sheet 10 is 0.1 to 0.35 times the thickness of the patch body 1, and preferably the thickness of the shaping sheet 10 is 0.185 times the thickness of the patch body 1. The patch body 1 can effectively reduce the probability of deformation of the patch body 1 during the morphological change from the storage state to the installation state through the configuration of the shaping sheet 10. The configuration of the first mounting hole 101 and the second mounting hole 102 makes the installation of the laser transmitter 12 and the laser receiver 13 easier and more accurate, and can effectively reduce the alignment and calibration work of the two. It can also reduce the probability of deformation of the patch body 1 in the later complex working environment, which is conducive to the stable operation of the deformation monitoring device.

[0021] Reference Figures 2 to 5 The patch device of this embodiment is dedicated to the deformation laser monitoring patch device, refer to Figure 2 The object to be monitored 2 includes a main beam 21 of the portal frame, a rigid support leg 22, and a flexible support leg 23. The deformation monitoring patch can be configured on multiple side walls of the main beam 21. Figure 3 , Figure 4 The top surface of the patch body 1 is fixed with a laser transmitter 12, a laser receiver 13, a control device 14 and an alarm 15. The control device 14 can be configured with an independent power supply or an external power supply. The laser transmitter 12 and the laser receiver 13 are fixedly arranged at the two ends of the length direction of the patch body 1. Figure 2 , Figure 5, the length extension direction of the patch body 1 is perpendicular to the load force (F force) direction of the monitored body 2. The laser receiver 13 includes a laser receiving end face, which extends along the width direction of the patch body 1. The laser receiving end face is symmetrically distributed from its center to the outer ends on both sides, and is set as a normal deformation area 131, a deformation warning area 132 and a deformation alarm area 133; the normal deformation area 131 is regarded as a normal deformation area before receiving the laser signal to the deformation warning area 132; the deformation warning area 132 is regarded as a deformation warning area before receiving the laser signal to the deformation alarm area 133, and the monitored body with the warning needs to be repaired; the deformation alarm area 133 is regarded as a deformation alarm area when receiving the laser signal, and the crane operation should be stopped immediately. When the monitored body 2 is working within the rated load range in a healthy state, the laser emitted by the laser transmitter 12 is in the normal deformation area 131. Figure 5 As shown, when the monitored object 2 is working and subjected to the force F as shown in the figure, the monitored object 2 is deformed, the laser emitter 12 is deflected in the direction of the arrow a in the figure, and the laser receiver 13 is deflected in the direction of the arrow b in the figure, thereby causing the laser emitted by the laser emitter 12 to be deflected. The control device 14 is used to receive, process and store the signal of the laser receiver 13, and the alarm 15 is used to receive the command of the control device 14 and issue a corresponding alarm.

[0022] Continue to refer to Figure 2 The length of the patch body 1 is 0.1 to 0.99 times the length of the monitored object 2. Preferably, the length of the patch body 1 is 0.16, 0.2, 0.4, 0.5, 0.85, 0.9, 0.95 or 0.99 times the length of the monitored object 2. The monitoring accuracy of the laser monitoring patch is obviously improved with the increase of the length of the patch body 1. Figure 2 When the patch body 1 is bonded to the main beam 21 of the monitored object 2, the patch body 1 covers all active areas of the vehicle 211 of the monitored object 2, and / or the patch body 1 is evenly distributed in all active areas of the vehicle 211 of the monitored object 2, such as Figure 2 As shown, the local configuration of the deformation monitoring patch can monitor the local area of ​​the monitored object 2 more specifically, so as to obtain a more accurate deformation location, which is beneficial to the inspection and maintenance of the monitored object 2.

[0023] Continue to refer to Figure 3 , Figure 4 The patch body 1 is provided with one or more groups of laser emitters 12 and laser receivers 13; the multiple groups of laser emitters 12 and laser receivers 13 are distributed side by side along the width direction of the patch body 1, and the multiple groups of laser receivers 13 are respectively connected to one of the control devices 14.

[0024] Continue to refer to Figure 4The control device 14 is equipped with a first alarm and a second alarm. The first alarm is arranged in the closed area. The second alarm is wirelessly connected to the control device 14. The second alarm 15 is arranged in the control room 24 and the monitoring room. The alarm 15 is an acoustic and / or optical alarm 15. The deformation normal area 131, the deformation warning area 132 and the deformation alarm area 133 have corresponding acoustic and / or optical alarms with obvious differences when receiving laser light, so that external personnel can directly observe the alarm information.

[0025] Continue to refer to Figures 2 to 5 The laser monitoring patch of this embodiment can be directly fixed and pasted on the required monitoring surface of the monitored object 2, which is simple to install and easy to operate; the deformation of the monitored object 2 is amplified by the coordinated use of the laser transmitter 12 and the laser receiver 13, and real-time monitoring, recording and alarm processing are performed through the control device 14, which can effectively monitor the deformation of the monitored object 2 and reduce the risk of crane operation.

[0026] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
