Description

Technical Field

[0001] This utility model relates to the technical field of railing detection devices, and in particular to a non-destructive self-balancing railing horizontal load detection device. Background Technology

[0002] In buildings, bridges, staircases, and other similar structures, railings serve as crucial safety protection facilities, and their load-bearing capacity and stability are of paramount importance. To ensure that railings can withstand horizontal thrust during actual use and prevent safety accidents, horizontal load testing is necessary.

[0003] Horizontal load on a railing refers to the horizontal force applied to the railing under certain conditions to simulate the lateral load that may occur in actual use. This force may cause displacement or deformation of the railing; therefore, horizontal load testing can assess the stability and resistance to deformation of the railing when subjected to lateral forces.

[0004] In existing technologies, the detection is usually carried out by using a reaction wall to provide reaction force or by setting expansion bolts on the ground. However, when there is no reaction wall around the railing to be tested and it is inconvenient to set expansion bolts on the ground, it is impossible to detect the horizontal load of the railing. Utility Model Content

The support assembly includes a base box, a vertical rod, and a diagonal rod. The end of the diagonal rod is provided with a roller. The vertical rod can be stored in the base box, and the diagonal rod is detachably connected to the vertical rod. During the detection process, the base box is placed between the railing and the floor suction cup, the vertical rod is at a right angle to the base box, and the diagonal rod intersects with the vertical rod. The steel wire rope passes through the roller, and the floor suction cup is located directly below the roller.

[0008] Furthermore, it also includes a first fastener, the vertical rod is provided with an adjustment structure, the inclined rod is provided with a plurality of openings, the detection process adjustment structure is aligned with one of the openings, the first fastener passes through the opening and the adjustment structure, and fixes the inclined rod on the vertical rod, by swinging the angle of the inclined rod, the openings at different positions are aligned with the adjustment structure, thereby realizing the fixed position adjustment of the inclined rod.

[0009] Furthermore, the adjustment structure can be any one of a through groove, a plurality of through holes, or a plurality of threaded holes.

[0010] Furthermore, it also includes a knotter, which has a spring inlet and a spring outlet, the spring inlet and the spring outlet being arranged side by side to form a figure-eight shape.

[0011] Furthermore, the knotter includes a housing, a cover, a spring, several steel balls, and a telescopic shaft. The housing includes a large opening end and a small opening end.

[0013] Furthermore, it also includes a second fastener. The base box has several holes on one side, and the opposite end of the inclined rod with the roller has a round hole. The second fastener is inserted into the round hole and tightened. The inclined rod is fixedly connected to the base box.

[0014] Furthermore, the bottom of the base box is provided with an anti-slip pad.

[0015] Furthermore, the base box is provided with a storage space for placing the vertical rod, the double hook tensioner, the wire rope and the force sensor.

[0016] Furthermore, the first and second fasteners are screws, nuts, or quick-release pins.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: using a floor suction cup as a reaction force fixing device, a steel wire rope is used to connect the railing, double hook tensioner, force sensor and floor suction cup in sequence, and the steel wire rope passes through the rollers on the triangular stable structure formed by the base box of the support component, the vertical rod and the diagonal rod to form a quadrilateral profile with diagonals.

[0031] Please refer to Figures 1-5This utility model provides a non-destructive self-balancing railing horizontal load detection device, including a double-hook tensioner 1, several sections of steel wire rope 2, a force sensor 3, a floor suction cup 4, and a support assembly 5. The floor suction cup 4 serves as a reaction force fixing device. The steel wire ropes 2 are sequentially connected to the railing 10, the double-hook tensioner 1, the force sensor 3, and the floor suction cup 4. The support assembly 5 includes a base box 51, a vertical rod 52, and an inclined rod 53. The end of the inclined rod 53 is provided with a roller 531. The base box 51 is placed between the railing 10 and the floor suction cup 4. The vertical rod 52 can be stored in the base box 51. The inclined rod 53 is detachably connected to the vertical rod 52. During the detection process, the vertical rod 52... 2 is perpendicular to the base box 51, and during the detection process, the inclined rod 53 and the vertical rod 52 intersect. The steel wire rope 2 passes through the roller 531, and the floor suction cup 4 is located directly below the roller 531. The railing 10, the steel wire rope 2, the double hook tensioner 1, the force sensor 3, the floor suction cup 4, and the floor 11 form a quadrilateral profile. The inclined rod 53 serves as the diagonal of the quadrilateral. The double hook tensioner 1 is operated to tighten the railing 10. The tension force is equivalent to the thrust on the railing 10. The force sensor 3 measures the tension force, which is equivalent to measuring the force on the railing 10. This achieves non-destructive self-balancing horizontal load detection, thus eliminating the need for a reaction wall or expansion bolts on the ground.

[0032] In actual testing, railings 10 of different heights will be encountered. To accommodate railings 10 of different heights, the diagonal bar 53 is designed to swing, as detailed below:

[0033] It also includes a first fastener 6. The vertical rod 52 is provided with an adjustment structure 521. The inclined rod 53 is provided with a plurality of openings 532. During the detection process, the adjustment structure 521 is aligned with one of the openings 532. The first fastener 6 passes through the opening 532 and the adjustment structure 521 and fixes the inclined rod 53 on the vertical rod 52. By swinging the angle of the inclined rod 53, the openings 532 at different positions are aligned with the adjustment structure 521, thereby realizing the fixed position adjustment of the inclined rod 53.

[0034] Option 1: The adjustment structure 521 is a through groove, and the first fastener 6 is a screw and nut. After determining that the position of the roller 531 is aligned with the height of the railing 10, as long as the opening 532 on the inclined rod 53 is aligned with the position of the through groove, the screw is inserted and tightened with the nut to fix the inclined rod 53 and achieve the height matching between the inclined rod 53 and the railing 10.

[0035] Option 2: The adjustment structure 521 is a through hole, and the first fastener 6 is a screw and nut. After determining the position of the roller 531 and the height alignment with the railing 10 and the corresponding through hole on the vertical rod 52, the screw is inserted and tightened with the nut to fix the inclined rod 53 and achieve the height matching between the inclined rod 53 and the railing 10.

[0036] Option 3: The adjustment structure 521 is a threaded hole, and the first fastener 6 is a screw and nut. After determining the position of the roller 531 and the height alignment with the railing 10 and the corresponding threaded hole on the vertical rod 52, the screw is inserted and tightened with the nut to fix the inclined rod 53 and achieve the height matching between the inclined rod 53 and the railing 10.

[0037] Compared to through holes and threaded holes, through slots have less fixed positions and are more flexible; while the difference between threaded holes and through holes is that screws need to be rotated when inserted into threaded holes, resulting in a tighter connection.

[0038] Since the steel wire rope 2 needs to be threaded through the railing 10 and fixed at one end, in order to make the steel wire rope 2 knotted more quickly, the detection device also includes a knotter 7. The knotter 7 includes a spring clip inlet 71 and a spring clip outlet 72. The spring clip inlet 71 and the spring clip outlet 72 are arranged side by side to form an 8 shape. When the steel wire rope 2 is threaded through the spring clip inlet 71 or the spring clip outlet 72, the steel wire rope 2 can be fixed. In addition, while pressing the spring clip inlet 71 or the spring clip outlet 72, the steel wire rope 2 can also be pulled, thereby fixing the connection between the steel wire and the railing 10 tightly.

[0039] Specifically, the knotter 7 includes a housing 73, a cover 74, a spring 75, several steel balls 76, and a telescopic shaft 77. The housing 73 includes a large opening end 731 and a small opening end 732. The cover 74 is disposed at the large opening end 731, and the tail end of the telescopic shaft 77 is exposed at the small opening end 732. The spring 75 and several steel balls 76 are all disposed inside the housing 73. The spring 75 is disposed between the cover 74 and the telescopic shaft 77. The telescopic shaft 77 is provided with a receiving opening 771, and the steel ball 76 is disposed in the receiving opening 771. By pressing the telescopic shaft 77, the spring 75 is deformed, and the steel ball 76 retracts into the gap between the telescopic shaft 77 and the housing 73. When the telescopic shaft 77 is released, the spring 75 returns to its original state, and the steel wire rope 2 passes into the spring clip inlet 71 or the spring clip outlet 72. The thicker end of the telescopic shaft 77 presses against the steel ball 76, and the steel ball 76 remains convex, thereby clamping the steel wire rope 2.

[0040] In the actual testing process, the railing 10, which is composed of steel pipes and glass, has no gap between the glass and the railing 10, making it impossible for the steel wire rope 2 to be fixed to the railing 10 by threading it through. The testing device is designed to include a glass suction cup 8, which is connected to the steel wire rope 2. The glass suction cup 8 can be an electric suction cup, which is not so easy to detach from the glass. The glass suction cup 8 is used to adhere to the glass, replacing the rope railing 10.

[0041] In another embodiment, in order to keep the bottom end of the inclined rod 53 stable, a second fastener 9 is also included. A plurality of holes 513 are provided on one side of the base box 51, and a round hole 533 is provided on the opposite end of the inclined rod 53 with the roller 531. The second fastener 9 is inserted into the round hole 533 and the hole 513, and the second fastener 9 is tightened. The inclined rod 53 is fixedly connected to the base box 51, thereby fixing the bottom end of the inclined rod 53 firmly.

[0042] In addition, to prevent excessive force when operating the double hook tightener 1, which could cause the support component 5 to move, the bottom of the base box 51 is provided with an anti-slip pad 511, which can increase the friction between the support component 5 and the floor 11 and prevent the support component 5 from moving.

[0043] Specifically, the hinge connection method is as follows: the base box 51 is provided with a bearing seat and a shaft core, the vertical rod 52 is provided with a through hole, the through hole is aligned with the bearing seat, and the shaft core passes through the bearing seat and the shaft core.

[0044] It is worth noting that the base box 51 is provided with a storage space 512, which is used to place the vertical rod 52, the double hook tensioner 1, the wire rope 2 and the force sensor 3, so that a complete set of testing tools can be placed in the storage slot, which is convenient for use and easy for inventory.

[0045] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
