Description

Technical Field

[0001] The present invention relates to the technical field of glass guardrail detection, and in particular to a device and method for detecting the horizontal load resistance performance of a glass guardrail. Background Art

[0002] Glass guardrails are usually located at high altitudes near the edge. As an important non-structural component of a building, its safety performance is particularly important. Therefore, it is crucial to control the construction quality of the glass guardrails and ensure their quality and safe use. At present, the usual practice for the industry to test glass guardrails is for the relevant parties to send the relevant materials to the testing agency, and then simulate the installation of various guardrails in the laboratory and conduct inspections. However, the test results of the laboratory are usually difficult to truly reflect the quality of on-site installation. At the same time, this method is time-consuming, labor-intensive and wasteful of materials. It cannot ensure the consistency of the materials used for the guardrails with the materials used on site, affecting the accuracy of the guardrail's horizontal load resistance data; in addition, some existing technologies related to on-site glass guardrail detection devices generally apply impact force to a certain position on the glass guardrail by configuring components, and judge whether the horizontal bearing capacity of the glass guardrail at the measured position meets the safety standard through the damage caused by the impact load to the glass guardrail. Among them, the counterweight component is usually released manually to generate the impact force by gravity. For this reason, the load value that can be applied is too single. Since different usage scenarios have different strength requirements for glass guardrails, the detection equipment for glass guardrails must have a certain load application range to meet the detection needs of glass guardrails with different strengths for horizontal load resistance performance; up to now, the industry has not yet integrated a complete and easy-to-operate detection device suitable for construction sites for the detection method of glass guardrail resistance to horizontal load performance. In view of this, research and improvement are conducted on the existing problems. The present invention aims to propose a device and method for detecting the horizontal load resistance performance of glass guardrails to solve the problems raised in the above-mentioned background technology.

[0018] Before introducing the technical solution of the present invention, it is necessary to explain the background of the invention. It is common that, at present, the usual practice of the industry for glass guardrail inspection is that the relevant parties send the relevant materials to the inspection agency, and then simulate the installation of various guardrails in the laboratory and conduct inspections. However, the inspection results of the laboratory are usually difficult to truly reflect the quality of on-site installation. At the same time, this method is time-consuming, labor-intensive and wasteful of materials, and cannot ensure the consistency of the materials used for the guardrail with the materials used on site, which affects the accuracy of the guardrail's horizontal load resistance data; in addition, some existing on-site glass guardrail inspection devices generally use components to inspect a certain part of the glass guardrail. An impact force is applied at a certain position, and the damage caused by the impact load to the glass guardrail is used to determine whether the horizontal bearing capacity of the glass guardrail at the measured position meets the safety standards. Usually, the counterweight component is released manually to generate an impact force due to gravity, and the load value that can be applied for this reason is too single. Due to different usage scenarios, the strength requirements of the glass guardrail are also different. Therefore, the glass guardrail detection equipment must have a certain load application range to meet the detection needs of the horizontal load resistance performance of glass guardrails of different strengths. Up to now, the industry still has not integrated a set of complete and easy-to-operate detection devices suitable for construction sites for the detection method of the horizontal load resistance performance of glass guardrails.

[0019] In order to overcome the technical problems of the prior art mentioned above, the present invention aims to provide a device and method for detecting the horizontal load resistance performance of glass guardrails.

[0020] See also Figure 1 and Figure 2 The exemplary embodiment of the present invention first provides a device for testing the horizontal load resistance of glass guardrails, which includes a base 1, a gantry bracket 3 and a loading mechanism. Among them, a support rod 13 is provided on the top of the base 1, and the top of the support rod 13 can be vertically and movably connected to the first baffle 2; the gantry bracket 3 includes a first side rod 31 and a second side rod 32 of equal length, the bottom of the first side rod 31 is fixedly connected to the inside of the first baffle 2, and the bottom of the second side rod 32 is fixedly connected to the second baffle 4; the loading mechanism includes two groups of thrust frames 5 respectively slidably connected to the outside of the first baffle 2 and the outside of the second baffle 4, and the two groups of thrust frames 5 are provided with suction cups 6 on opposite sides; in addition, the loading mechanism also includes two groups of vertical hydraulic Jack, the two groups of thrust frames 5 are both equipped with hydraulic cylinders 7 of the vertical hydraulic jack, the fixed end of any hydraulic cylinder 7 is fixedly connected to the first baffle 2 or the second baffle 4, the ejection end of any hydraulic cylinder 7 abuts against the corresponding thrust frame 5, and a controllable loading mechanism is used to apply a precise and controllable thrust to the glass guardrail, and the thrust range of the loading mechanism can meet the glass guardrail detection requirements in different usage scenarios. Preferably, the thrust range generated by the thrust frame 5 under the action of the vertical hydraulic jack is 0-2000N.

[0021] The connection relationship between the base 1 and the gantry support 3 of the detection device is described below: See also Figure 1 and Figure 2 The main body of this detection device is composed of a base 1 and a gantry bracket 3. The base 1 is set on the ground, and a support rod 13 is provided on the top. Because the detection position for detecting the horizontal load resistance performance of the glass guardrail is usually located at the center of the glass guardrail, one of the functions of the support rod 13 is to provide a certain installation height for the subsequent loading mechanism, and the second function of the support rod 13 is to serve as the installation basis of the gantry bracket 3. The top of the support rod 13 is vertically movably connected to the first baffle 2. Specifically, the first baffle 2 includes a first chamber 22 equipped with a rack 24, and a second chamber 23 for fixing the first side rod 31; the support rod 13 is provided with a gear meshing with the rack 24 for transmission, and a handle 21 is provided at the end of the gear and passes through the first baffle 2; further, a ratchet mechanism is provided between the handle 21 and the gear, and the ratchet mechanism is used to limit the vertical movement of the first baffle 2; it should be understood that the ratchet mechanism includes at least a ratchet and a rocker arm with a pawl. For example, when installing this detection device, the handle 21 is rotated to make the first baffle 2 move vertically upward along the support rod 13 to the desired position. When the detection personnel releases the handle 21, the pawl prevents the ratchet from rotating, thereby achieving the self-locking height of the first baffle 2. Furthermore, the bottom of the first side rod 31 of the gantry bracket 3 is fixedly connected to the first chamber 22 of the first baffle 2, that is, the top of the support rod 13 can be vertically movably connected to the first baffle 2, which is equivalent to the top of the support rod 13 being vertically movably connected to the gantry bracket 3. It should be noted that the present invention does not limit the specific structure of the ratchet mechanism, and it only needs to meet the requirement that the first baffle 2 can be self-locking.

[0022] In some embodiments, see Figure 1 and Figure 2 A plurality of reinforcing ribs 12 are provided between the support rod 13 and the base 1 , and the function of the reinforcing ribs 12 is to improve the connection reliability between the support rod 13 and the base 1 .

[0023] In some embodiments, see Figure 1 and Figure 2The bottom of the base 1 is provided with a retractable universal wheel 11. By providing the universal wheel 11, the detection device has the technical advantage of being easy to carry. Furthermore, the universal wheel 11 is retractable. Specifically, a receiving cavity is provided at the bottom of the base 1. The receiving cavity is surrounded by an electric folding rod or a telescopic rod. The end of the electric folding rod or the telescopic rod is equipped with a universal wheel. Then, when the detection device moves to a specified position, the folding rod or the telescopic rod is electrically controlled to be stored in the receiving cavity at the bottom of the base 1, that is, the universal wheel 11 can be retracted, so that the large surface of the bottom of the base 1 directly contacts the ground, thereby increasing the stability of the base 1. It should be noted that the present invention does not limit the retractable manner of the universal wheel 11. Furthermore, a number of bolt holes are evenly provided on the edges around the base 1 to fix it to the ground through fasteners to prevent overturning; or in some embodiments, the detection personnel can place a number of counterweights on the top of the base 1 to further prevent the base 1 from overturning.

[0024] In some embodiments, see Figure 1 and Figure 2 The gantry support 3 also includes a cross bar 33, and the second side bar 32 can move horizontally in the length direction of the cross bar 33 to clamp glass guardrails of different thicknesses. Specifically, a ruler is provided on the surface of the cross bar 33, and a plurality of first through holes 331 are provided at equal intervals on the surface of the cross bar 33. The top of the second side bar 32 is configured as a sliding hoop 321 that can move in the length direction of the cross bar 33. The sliding hoop 321 is provided with a second through hole with the same aperture as the first through hole 331. When the sliding hoop 321 moves to the required position, the inspection personnel will lock the first through hole 331 and the second through hole through a fastener to meet the clamping requirements of glass guardrails of different thicknesses.

[0025] The connection relationship of the loading mechanism of this detection device is described below: See also Figure 1 and Figure 2The loading mechanism is installed in conjunction with the first baffle plate 2 and the second baffle plate 4. Specifically, the loading mechanism includes two groups of vertical hydraulic jacks and two groups of thrust frames 5 respectively slidably connected to the outside of the first baffle plate 2 and the outside of the second baffle plate 4. Hydraulic cylinders 7 of vertical hydraulic jacks are installed in both groups of thrust frames 5. The fixed end of any hydraulic cylinder 7 is fixedly connected to the first baffle plate 2 or the second baffle plate 4. The ejection end of any hydraulic cylinder 7 abuts against its corresponding thrust frame 5. The thrust range generated by the thrust frame 5 under the action of the vertical hydraulic jack is 0-2000N. In order to realize the sliding connection of the thrust frame 5 to the corresponding outside of the first baffle 2 and the outside of the second baffle 4, as a preferred technical solution, a slide rail is provided at the bottom of the thrust frame 5, and a support portion 41 is provided on the outside of the first baffle 2 and the outside of the second baffle 4 in the horizontal direction, and a roller that can roll in the slide rail is provided on the top of the support portion 41, so that when the thrust frame 5 is ejected by the hydraulic cylinder 7 of the vertical hydraulic jack, the thrust frame 5 can realize the sliding function through the structure of the pulley and the slide rail. Further, as a preferred technical solution, the two inner sides of the thrust frame 5 along the length direction do not contact the outside of the first baffle 2 or the outside of the second baffle 4, so as to avoid friction when the thrust frame 5 slides on the outside of the first baffle 2 and the outside of the second baffle 4.

[0026] See also Figure 1 and Figure 2 , the two sets of thrust frames 5 are provided with suction cups 6 on opposite sides, and the suction cups 6 are provided with a pressing hand pump and an air release valve, and the suction cups 6 are used to align the loading mechanism with the detection position of the glass guardrail to be inspected, wherein the maximum suction force of the suction cups 6 can reach 3500N through the pressing hand pump, and the suction force of the suction cups 6 is greater than the load value applied by the loading mechanism. When in use, the inspector can manually move the thrust frame 5 to make the suction cups 6 absorb the detection position of the glass guardrail to be inspected, and remove the suction cups 6 through the air release valve after the inspection is completed.

[0027] In addition, based on the above-mentioned horizontal load resistance performance detection device for glass guardrail, the exemplary embodiment of the present invention also provides a detection method, which includes the following steps: Step 1, retract the universal wheel 11 to make the base 1 contact the ground; Step 2, adjusting the height of the first baffle 2 so that the gantry bracket 3 smoothly crosses the height of the glass guardrail to be inspected; Step 3, determine the detection position of the glass guardrail to be inspected, and absorb the glass guardrail to be inspected by the suction cup 6; Step 4: Use a vertical hydraulic jack to load, first apply a set load to the outer side of the glass guardrail, keep loading for a set time, and then unload; then apply a set load to the inner side of the glass guardrail, keep loading for a set time, and then unload; The thrust range of the thrust frame 5 under the action of the vertical hydraulic jack is 0-2000N. The test personnel adjust the set load value according to the glass guardrail test requirements in different usage scenarios. In addition, the set time for maintaining the loading is preferably 3 seconds.

[0028] It should be noted that when applying load using the vertical hydraulic jack of the loading mechanism, the load should be applied slowly and evenly without any impact. Step 5, loop step 4 to reach the specified number of loading times, observe the damage of the glass guardrail, and judge whether the construction quality of the glass guardrail meets the relevant standard requirements based on the observed damage of the glass guardrail.

[0029] In summary, the detection device and detection method based on the above structure have the following technical advantages: 1. The detection device of the present invention can be used at the construction site to truly reflect the on-site installation quality, ensure the accuracy of the glass guardrail's horizontal load resistance data, and effectively improve the detection efficiency; 2. The present invention uses a controllable loading mechanism to apply a precise and controllable thrust to the glass guardrail, which can quickly and accurately obtain the horizontal load resistance performance parameters of the glass guardrail to be inspected, and the thrust range of the loading mechanism can meet the glass guardrail detection requirements in different usage scenarios; 3. The detection device of the present invention has a simple and compact structure and strong operability. It has the advantages of being easy to carry and transport and adjustable in height, and has a wide range of on-site applications. Therefore, compared with the existing glass guardrail detection technology, the glass guardrail resistance performance detection device and detection method provided by the present invention have obvious technical advantages.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
