Description

Technical Field

[0001] The utility model relates to the technical field of anti - falling safety devices, and particularly relates to a detection device for an anti - falling safety device of a construction hoist. Background Art

[0002] With the booming development of the construction industry, the use of construction hoists is becoming increasingly frequent. As a vertical transportation device, construction hoists are widely used in construction projects such as high - rise buildings and bridges. However, there is a risk of falling during their operation. Once a falling accident occurs, it will cause serious casualties and property losses. In order to ensure the safe operation of construction hoists, anti - falling safety devices play a crucial role.

[0003] At present, the on - site detection of anti - falling safety devices mainly measures the displacement of disc springs with vernier calipers and calculates the braking distance through relevant calculation formulas. This method will produce human errors, and disassembly is required. Errors are also likely to occur during the disassembly process. At the same time, the disassembly work is cumbersome, wasting manpower and material resources. It cannot perform test experiments quickly and repeatedly, the test results are inaccurate, and the previous measuring equipment cannot measure the acceleration of the safety device at each time period. Therefore, we propose a detection device for an anti - falling safety device of a construction hoist;

[0004] The existing patent (publication number: CN211545588U) for the detection of an anti - falling safety device of a construction hoist: by adjusting the dial on the runner to the initial position, the safety device starts to work. When the unloading bolt rotates, it drives the runner to rotate. Each time the runner rotates one week, the dial generates an electric current on the current transmission rod, which is recorded by a data instrument. By measuring the rotation angle of the unloading bolt, the braking sliding distance of the hoist cage can be calculated, and then the braking distance can be calculated, so as to detect whether the safety device is a qualified product. It is convenient and fast without disassembly.

[0005] In view of the above problems, the existing patent gives a solution. The existing detection device for an anti - falling safety device of a construction hoist is not convenient for fixing anti - falling safety devices of different sizes. During the test, the anti - falling safety device is prone to shaking and displacement, resulting in inaccurate measured braking distance, and it is not convenient to simulate the motion states of the hoist under various actual working conditions, affecting the accuracy of the detection data.

[0006] Therefore, a detection device for an anti - falling safety device of a construction hoist is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] A detection device for an anti-falling safety device of a construction hoist, including a base 1, a simulated cage 2 is arranged at the bottom of the base 1, fixed components 4 are arranged on both sides inside the simulated cage 2, and test components 5 are arranged on both sides at the top of the base 1;

[0029] The fixed component 4 includes a hydraulic rod 401 bolted to the outside of the simulated cage 2, the output end of the hydraulic rod 401 is fixedly connected with a fixed frame 402, a driving motor 403 is bolted to the inside of the fixed frame 402, the output end of the driving motor 403 is fixedly connected with a double-shaft lead screw 404, a connecting block 405 is threadedly connected to the outside of the double-shaft lead screw 404, an electric gripper 406 is bolted to the outside of the connecting block 405, an anti-slip pad 407 is bonded to the inside of the electric gripper 406, and the anti-slip pad 407 is made of rubber.

[0030] In this embodiment: By starting the hydraulic rod 401, then the hydraulic rod 401 extends to push the fixed frame 402 to move inside the simulated cage 2. When the fixed frame 402 moves to a suitable position, then start the driving motor 403, and then the driving motor 403 drives the double-shaft lead screw 404 to rotate. Since the connecting block 405 is threadedly connected to the double-shaft lead screw 404, the rotation of the double-shaft lead screw 404 will cause the connecting block 405 to move towards or away from each other on the double-shaft lead screw 404, thereby driving the electric gripper 406 to approach or move away from the anti-falling safety device. Its rubber anti-slip pad 407 contacts and clamps the anti-falling safety device. The anti-slip pad 407 increases the friction force to ensure firm clamping and can also prevent scratching the surface of the anti-falling safety device.

[0031] Specifically, as Figure 3 , Figure 4 shown, the test component 5 includes a fixed frame 501 bolted to the top of the base 1, and a double-shaft servo motor 502 is clamped inside the fixed frame 501.

[0032] Specifically, as Figure 3 , Figure 4 shown, a auxiliary block 503 is fixedly connected to the top of the base 1, the output end of the double-shaft servo motor 502 penetrates through the auxiliary block 503, the output end of the double-shaft servo motor 502 is fixedly connected with a winding shaft 504, and a steel rope 505 is arranged inside the winding shaft 504.

[0033] Specifically, as Figure 3 shown, a fixing block 506 is fixedly connected to the bottom of the steel rope 505. A supporting block 507 is bolted inside the fixing block 506. The supporting block 507 is bolted to the simulation cage 2, and the inner side of the supporting block 507 is slidably connected to the base 1.

[0034] In this embodiment: By starting the dual-axis servo motor 502, then the output end of the dual-axis servo motor 502 drives the wire winding shaft 504 to rotate. Then, when the wire winding shaft 504 rotates, according to different rotation directions, the winding or unwinding action of the steel rope 505 is realized. Then, the steel rope 505 is connected to the simulation cage 2 through the fixing block 506 and the supporting block 507. When the wire winding shaft 504 winds the steel rope 505, the steel rope 505 pulls the supporting block 507, and the supporting block 507 drives the simulation cage 2 to rise. When the wire winding shaft 504 unwinds the steel rope 505, the simulation cage 2 descends under the action of gravity. Then, the descent speed and state are adjusted according to actual test requirements. At the same time, the inner side of the supporting block 507 is slidably connected to the base 1 to ensure the stable movement of the simulation cage 2 in the vertical direction. The dual-axis servo motor 502 can precisely control the rotation speed and direction, thereby simulating various complex working conditions such as the elevator rising or descending at a constant speed at different speeds, or simulating accelerating upward and decelerating downward.

[0035] Specifically, as Figure 4 shown, a support rod 6 is bolted to the top of the base 1. A solar panel 7 is movably connected inside the support rod 6. An installation seat 8 is bolted to the top of the base 1. A storage battery 9 is bolted to the top of the installation seat 8. The storage battery 9 is electrically connected to the solar panel 7. A connecting wire 10 is arranged outside the storage battery 9, and the connecting wire 10 is electrically connected to the dual-axis servo motor 502.

[0036] Specifically, as Figure 5 shown, a support plate 11 is bolted to the front side of the base 1. A tension sensor 12 is bolted to the front side of the support plate 11, and the tension sensor 12 is located outside the steel rope 505.

[0037] In this embodiment: By setting the support rod 6, solar panel 7, mounting base 8, storage battery 9 and connecting wire 10, the solar panel 7 is installed on the support rod 6, which can absorb solar energy and convert it into electrical energy. At the same time, the generated electrical energy is stored in the storage battery 9. Then, the storage battery 9 supplies power to the two-axis servo motor 502 through the connecting wire 10. In case of emergencies such as power outages, the electrical energy stored in the storage battery 9 can be used as an emergency power source to ensure that the detection work can continue, avoid interrupting the detection process due to power outages, and improve the continuity and stability of the detection work. By setting the support plate 11 and the tension sensor 12, during the simulation of the elevator operation, the steel rope 505 bears the gravity of the simulated cage 2 and the force changes during braking in the simulation of the elevator operation. At the same time, the tension sensor 12 can sense the tension magnitude on the steel rope 505 in real time and convert the tension signal into an electrical signal. This electrical signal is transmitted to the data acquisition system for signal processing and analysis, so as to obtain the force conditions of the simulated cage 2 in different operating states, facilitate the accurate measurement of the tension of the steel rope 505, and then accurately reflect the force changes of the simulated cage 2 during the entire detection process.

[0038] Specifically, as Figure 3 shown, a sliding groove 13 is formed inside the simulated cage 2, and a sliding block 14 is slidably connected inside the sliding groove 13. The sliding block 14 is bolted to the fixed frame 402.

[0039] Specifically, as Figure 1 shown, the bottom of the base 1 is fixedly connected with support legs 3, and rubber pads 15 are bonded to the bottoms of the support legs 3.

[0040] In this embodiment: By setting the sliding groove 13 and the sliding block 14, when the fixed frame 402 moves under the push of the hydraulic rod 401, the sliding block 14 slides synchronously in the sliding groove 13, effectively preventing the fixed frame 402 from shaking or misaligning during the movement, so as to ensure the position accuracy and clamping force uniformity of the subsequent electric gripper 406 when clamping the safety anti-falling device. By setting the support legs 3 and the rubber pads 15, the rubber pads 15 increase the friction with the ground to prevent the equipment from shaking during operation and affecting the correct evaluation of the performance of the safety anti-falling device.

[0041] Working principle: During the process of using the detection device for the anti-falling safety device of a construction hoist, first place the anti-falling safety device to be detected at the position to be fixed inside the simulation cage 2. Then, start the hydraulic rod 401 according to the size of the anti-falling safety device to be detected. Next, the hydraulic rod 401 extends and pushes the fixed frame 402 to move inside the simulation cage 2. When the fixed frame 402 moves to the appropriate position, then start the drive motor 403. Then, the drive motor 403 drives the double-axis lead screw 404 to rotate. Since the connecting block 405 is threadedly connected to the double-axis lead screw 404, the rotation of the double-axis lead screw 404 will cause the connecting block 405 to move towards or away from each other on the double-axis lead screw 404, thereby driving the electric gripper 406 to approach or move away from the anti-falling safety device. Its rubber anti-slip pad 407 contacts and clamps the anti-falling safety device. The anti-slip pad 407 increases the friction force to ensure firm clamping and can also prevent scratching the surface of the anti-falling safety device. At the same time, the sliding grooves 13 and sliding blocks 14 inside the simulation cage 2 are provided to ensure the stable movement of the fixed frame 402 during the pushing of the hydraulic rod 401 and the driving of the drive motor 403, preventing situations such as skewing from affecting the clamping effect. Then, start the double-axis servo motor 502. Then, the output end of the double-axis servo motor 502 drives the wire winding shaft 504 to rotate. Then, when the wire winding shaft 504 rotates, according to different rotation directions, the winding or unwinding action of the steel wire 505 is realized. Then, the steel wire 505 is connected to the simulation cage 2 through the fixed block 506 and the support block 507. When the wire winding shaft 504 winds the steel wire 505, the steel wire 505 pulls the support block 507, and the support block 507 drives the simulation cage 2 to rise. When the wire winding shaft 504 unwinds the steel wire 505, the simulation cage 2 descends under the action of gravity. Then, adjust the descent speed and state according to the actual test requirements. At the same time, the inner side of the support block 507 is slidably connected to the base 1 to ensure the stable movement of the simulation cage 2 in the vertical direction. The double-axis servo motor 502 can precisely control the rotation speed and direction, thereby simulating various complex working conditions such as the hoist rising or descending at a constant speed at different speeds, or simulating accelerating rising and decelerating descending.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
