Abstract
Description
Technical Field
[0001] This application relates to the field of guardrail testing equipment, specifically a device for testing the horizontal load of building guardrails. Background Technology
[0002] Balconies, staircases, exterior corridors, and other open areas of buildings must be equipped with railings. To ensure the safe use of the railings and achieve the purpose of protection, the horizontal load performance of the railings must meet certain requirements. Therefore, during the acceptance of engineering quality, testing equipment is usually needed to test the horizontal load performance of building railings.
[0003] A utility model patent with publication number CN221826454U discloses a guardrail horizontal load detection device, including a load loading unit, a contact positioning unit, a thrust sensing unit, and a displacement sensing unit. The load loading unit has a first end and a second end arranged opposite to each other. The first end can abut against a reaction support, and the second end is used to output the horizontal load. The contact positioning unit is located at the second end and has a positioning groove with its opening direction parallel to the load output direction, which can accommodate the guardrail. The thrust sensing unit is located within the load loading unit, and the displacement sensing unit is used to sense the horizontal displacement of the guardrail in the thrust direction. The load loading unit does not need to be connected and fixed to the ground, eliminating the need for a vertical support structure. The overall structure of the device is simpler and more compact, facilitating transportation and simplifying installation and fixing steps. Assembly is faster, saving manpower and resources and improving detection efficiency.
[0004] The device is equipped with a load loading unit, which has a first end and a second end that are positioned opposite each other. When testing the horizontal load of the guardrail, the staff will bring the contact positioning unit on the second end into contact with the guardrail to be tested, and bring the first end into contact with the reaction support. However, some guardrails have open sides, which cannot provide support for the first end to be brought into contact, making it inconvenient to conduct effective testing and limiting its applicability. Utility Model Content
[0005] To address the issue of limited applicability in existing technologies, this utility model provides a device for detecting the horizontal load on building railings.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] This utility model provides a horizontal load detection device for building guardrails, including a base, which is L-shaped. A fixed plate is slidably mounted on the top of the base, and a hydraulic cylinder is fixedly mounted on one side of the fixed plate. A connecting seat is fixedly mounted on both the base and the fixed plate. A support rod is hinged to the connecting seat on the base. The support rod has a countersunk hole, and an adjusting rod is inserted into the countersunk hole. The adjusting rod has a threaded section, and a sleeve is fitted onto the threaded section of the adjusting rod outside the countersunk hole. The end of the adjusting rod away from the support rod is hinged to the connecting seat on the fixed plate. An anchor hole is provided on the base, and an anchor rod is inserted into the anchor hole.
[0008] It also includes a measuring mechanism, which is mounted on a fixed plate.
[0009] Preferably, the measuring mechanism includes an electric push rod, a mounting plate, a slider, a backing plate, and a plug rod. The electric push rod is fixedly mounted on one side of the hydraulic cylinder on the mounting plate. The output shaft of the electric push rod is fixedly mounted on the mounting plate. The mounting plate has a through hole that matches the output shaft of the hydraulic cylinder. The mounting plate has a groove along its length, and a slider slides within the groove. A backing plate is mounted on the side of the slider away from the fixed plate, and a plug rod is fixedly mounted on the side of the backing plate. The slider has a plug hole that matches the plug rod. When the operator starts the electric push rod, the output shaft of the electric push rod drives the mounting plate to slide, bringing the mounting plate closer to the guardrail. When the mounting plate slides to the position directly below the guardrail, the operator slides the slider along the groove, causing the slider to move the backing plate to the position to be measured. Then, the operator slides the fixed plate and the backing plate, so that the backing plate abuts against the side of the guardrail away from the fixed plate. This allows the guardrail to deform and compress the backing plate, thereby causing the backing plate and the plug rod to slide. The operator can judge the load performance of the guardrail by observing the sliding distance of the backing plate. The operation is convenient.
[0010] Preferably, the number of sliders is multiple sets and they are spaced apart in the slide groove. By setting multiple sets of sliders, deformation detection can be performed on multiple points of the guardrail, thereby obtaining more comprehensive detection data.
[0011] Preferably, a locking block is fixedly provided on the slider, and a slot is provided on the inner wall of the slide groove to match the locking block. By setting the locking block and the slot, the slider is further limited to ensure the stability of the slider during the sliding process.
[0012] Preferably, both the insertion rod and the mounting plate are provided with scale lines along their length. By providing scale lines, it is convenient for operators to intuitively record the displacement distance of the backing plate and the distance between multiple sets of sliders, making operation convenient.
[0013] Preferably, the top of the base is provided with a mounting groove, and an electric push rod two is fixedly installed in the mounting groove. The output shaft of the electric push rod two is fixedly connected to the fixed plate. When the operator starts the electric push rod two in the mounting groove, the output shaft of the electric push rod two drives the fixed plate to rise and fall, which is convenient to operate.
[0014] Preferably, the number of support rods is multiple sets and they are spaced apart on the base. By setting multiple sets of support rods, the fixing plate can be supported at multiple points, ensuring the stability of the fixing plate during testing.
[0015] The advantages of adopting the above technical solution are:
[0016] This utility model includes an L-shaped base with a fixed plate slidably mounted on its top. A hydraulic cylinder is fixedly mounted on one side of the fixed plate. Connecting seats are fixedly mounted on both the base and the fixed plate. A support rod is hinged to the connecting seat on the base. The support rod has a countersunk hole, into which an adjusting rod is inserted. The adjusting rod has a threaded section, and a retaining sleeve is fitted onto the threaded section of the adjusting rod outside the countersunk hole. The end of the adjusting rod away from the support rod is hinged to the connecting seat on the fixed plate. During testing, the operator can perform a contact test on the guardrail by activating the hydraulic cylinder on the fixed plate. The adjustable support rod and adjusting rod further support the fixed plate, ensuring the stability of the test. No external counter-support is required, thus expanding the applicability.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] like Figure 1-3 As shown in the figure, this utility model embodiment discloses a horizontal load detection device for building guardrails, including a base 1 and a measuring mechanism. The base 1 is L-shaped, and a fixing plate 2 is slidably disposed on the top of the base 1. A hydraulic cylinder 3 is fixedly disposed on one side of the fixing plate 2. A connecting seat 101 is fixedly disposed on both the base 1 and the fixing plate 2. A support rod 4 is hinged to the connecting seat 101 on the base 1. The support rod 4 is provided with a countersunk hole, and an adjusting rod 5 is inserted into the countersunk hole. The adjusting rod 5 is provided with a threaded section. A retaining sleeve 501 is threadedly fitted onto the section of the adjusting rod 5 outside the countersunk hole. The end of the adjusting rod 5 away from the support rod 4 is hinged to the connecting seat 101 on the fixing plate 2. An anchor hole 1011 is provided on the base 1, and an anchor rod is inserted into the anchor hole 1011. The measuring mechanism is disposed on the fixing plate 2.
[0024] In at least one embodiment, the measuring mechanism includes an electric push rod 6, a mounting plate 7, a slider 8, a backing plate 9, and a insertion rod 901. The electric push rod 6 is fixedly mounted on one side of the hydraulic cylinder 3 on the mounting plate 2. The output shaft of the electric push rod 6 is fixedly mounted on the mounting plate 7. The mounting plate 7 has a through hole 701 that mates with the output shaft of the hydraulic cylinder 3. The mounting plate 7 has a groove 702 along its length, and the slider 8 is slidably mounted within the groove 702. A backing plate 9 is mounted on the side of the slider 8 away from the mounting plate 2. The insertion rod 901 is fixedly mounted on one side of the backing plate 9. The slider 8 has an insertion hole that mates with the insertion rod 901. When the operator activates the electric push rod 6, the electric push rod... The output shaft of the 6-axis drives the mounting plate 7 to slide, bringing the mounting plate 7 close to the guardrail. When the mounting plate 7 slides to the bottom of the guardrail, the operator slides the slider 8 along the slide groove 702, causing the slider 8 to move the back plate 9 to the position to be measured. Then, the operator slides the fixed plate 2 and the back plate 9, so that the back plate 9 abuts against the side of the guardrail away from the fixed plate 2, and the mounting plate 7 abuts against the side of the guardrail close to the fixed plate 2. This allows the back plate 9 to be squeezed when the guardrail deforms, thereby causing the back plate 9 and the insertion rod 901 to slide. The operator can judge the load performance of the guardrail by observing the sliding distance of the back plate 9. The operation is convenient.
[0025] In at least one embodiment, the number of sliders 8 is multiple sets and they are spaced apart in the slide groove 702. By setting multiple sets of sliders 8, deformation detection can be performed on multiple points of the guardrail, thereby obtaining more comprehensive detection data.
[0026] In at least one embodiment, a locking block is fixedly provided on the slider 8, and a slot 703 that matches the locking block is provided on the inner wall of the slide groove 702. By setting the locking block and the slot 703, the slider 8 is further limited, ensuring the stability of the slider 8 during the sliding process.
[0027] In at least one embodiment, both the insertion rod 901 and the mounting plate 7 are provided with scale lines along the length direction. By providing scale lines, it is convenient for operators to intuitively record the displacement distance of the backing plate 9 and the distance between multiple sets of sliders 8, making the operation convenient.
[0028] In at least one embodiment, the top of the base 1 is provided with a mounting groove, and an electric push rod 102 is fixedly installed in the mounting groove. The output shaft of the electric push rod 102 is fixedly connected to the fixed plate 2. When the operator starts the electric push rod 102 in the mounting groove, the output shaft of the electric push rod 102 drives the fixed plate 2 to move up and down, which is convenient to operate.
[0029] In at least one embodiment, the number of support rods 4 is multiple sets and they are spaced apart on the base 1. By setting multiple sets of support rods 4, the fixing plate 2 is supported at multiple points, ensuring the stability of the fixing plate 2 during testing.
[0030] During the horizontal load testing of the guardrail, the worker moves the base 1 to one side of the guardrail, then drills the anchor rods into the ground through the anchor holes 1011 to fix the base 1. Next, the worker slides the fixing plate 2 on the base 1 according to the height of the guardrail, aligning the output shaft of the hydraulic cylinder 3 on the fixing plate 2 with the guardrail. The worker then activates the hydraulic cylinder 3, causing its output shaft to abut against the guardrail and apply a horizontal load. The worker then observes the deformation of the guardrail to assess its load-bearing capacity. As the fixing plate 2 rises along the base 1, the support rod 4 and the adjusting rod 5 rotate along the connecting seats 101 on the base 1 and the fixing plate 2, respectively. The adjusting rod 5 slides and extends along the countersunk hole in the support rod 4. When the fixed plate 2 rises to a suitable height, the operator rotates the retaining sleeve 501 on the adjusting rod 5 so that the retaining sleeve 501 approaches and abuts against the support rod 4. The abutment between the retaining sleeve 501 and the support rod 4 further limits the fixed plate 2, preventing it from sliding down. The combination of the support rod 4 and the adjusting rod 5 provides auxiliary support for the fixed plate 2, ensuring the stability of the load detection of the guardrail by the output shaft of the hydraulic cylinder 3, thus improving the applicability. During the process of applying load to the guardrail by the output shaft of the hydraulic cylinder 3, the measuring mechanism on the fixed plate 2 can measure the deformation of the guardrail in real time, which is convenient for the operator to observe.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
