Description

Technical Field

[0001] This utility model relates to the technical field of drop test devices for ton bags, specifically drop test devices for ton bags. Background Technology

[0002] With the rise of various manufacturing industries and the transfer and transportation of materials, ton bags are used to package bulk materials, facilitating the packaging and transportation of granular materials. They are widely used in chemical, construction, and food industries. However, in actual logistics transportation environments, ton bags often fall due to loading and unloading errors, transportation bumps, etc., leading to ton bag breakage and material leakage, resulting in safety accidents and material waste. Therefore, drop tests are necessary to verify the reliability of ton bags. Drop tests typically involve lifting with a forklift and manually disengaging the lifting ropes. While experiments can be conducted in this way, the forklift operator's field of vision is limited, and there are risks of being injured by falling or crushing fully loaded ton bags when manually cutting the lifting rope at close range. Uneven ground can also cause uneven impact force with each drop, making it impossible to obtain accurate drop test data. Furthermore, repeated impacts can easily damage the road surface. Adjusting the height of the ton bags depends on the forklift driver's experience and the action of cutting the lifting rope, making it susceptible to interference from various factors. This makes it difficult to meet the needs of batch and standardized experiments, resulting in inconvenient and unsafe operation, as well as inaccurate data. Utility Model Content

[0003] The purpose of this invention is to provide a ton bag drop test device to solve the problems mentioned in the background art, such as easy injury during testing and inconvenient operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a ton bag drop test device, comprising a crossbeam, a lifting mechanism placed against the outer surface of the crossbeam, and waist-shaped holes evenly distributed on the side of the lifting mechanism near the crossbeam; a power supply box fixedly installed on the outer surface of the crossbeam near the lifting mechanism; a control box fixedly installed on the ground below the crossbeam; a lifting trolley threaded through the steel cable of the lifting mechanism, and the lifting trolley located below the lifting mechanism; a U-shaped ring rotatably installed on the outer surface of the lifting trolley, and the U-shaped ring and the lifting trolley connected by bolts; a release device rotatably installed on the outer surface of the U-shaped ring, and the outer surface of the release device fitting against the outer surface of the U-shaped ring; an electric push rod fixedly installed on the side surface of the release device, and the output end of the electric push rod fitting against the outer surface of the release device.

[0005] Preferably, a steel plate is fixedly embedded in the ground below the crossbeam, and the steel plate protrudes from the ground. The steel plate is located below the unhooking device, and the unhooking device is located at the center of the steel plate.

[0006] By adopting the above technical solution, the steel plate protruding from the ground can facilitate the cleaning of the contents from the steel plate after the ton bag is damaged and broken, and reduce the contamination of dust. At the same time, the use of steel plate can ensure the flatness of the ground when the ton bag is dropped, so that the ton bag will not cause measurement errors due to uneven ground, and the ton bag will not damage the ground due to falling during measurement.

[0007] Preferably, a positioning warning tape is adhered and fixed to the outer surface of the steel plate, and the positioning warning tape is the same size as the ton bag. The positioning warning tape forms a square frame, and the geometric center of the square frame formed by the positioning warning tape coincides with the installation center of the unhooking device.

[0008] By adopting the above technical solution, the positioning warning tape forming a square can be used to position the ton bag so that when the ton bag is placed on the steel plate, it is exactly below the hook release device. When the ton bag is passed through and lifted by the hook release device, it will not shake or fall during the lifting process due to incorrect positioning.

[0009] Preferably, a fixing rod is inserted through the waist-shaped hole of the elevator, and the fixing rod is fixed to the elevator with a nut, and the outer surface of the fixing rod is in contact with the outer surface of the crossbeam.

[0010] By adopting the above technical solution, the lifting platform can be easily fixed to the outer surface of the crossbeam by means of a fixing rod and a nut, which greatly improves the convenience of the lifting platform installation. At the same time, the installation direction of the fixing rod ensures that the fixing rod only bears tensile force rather than shear force, which greatly reduces the risk of the fixing rod breaking due to excessive weight during use.

[0011] Preferably, warning posts are placed around the steel plate, and one end of each warning post is equipped with a telescopic isolation strip, which is inserted into another warning post. A micro switch is fixedly installed on the outer surface of each warning post, and the outer surface of the micro switch is in contact with the outer surface of the telescopic isolation strip. The micro switch is connected to a control box.

[0012] By adopting the above technical solution, the steel plate can be easily isolated by placing warning posts and stretching telescopic isolation belts. The connection between the telescopic isolation belts and the warning posts can be detected by microswitches. If the telescopic isolation belts are not fixed in place, the elevator cannot work to lift the ton bags, which greatly reduces the danger caused by workers conducting inspections before leaving the steel plate.

[0013] Preferably, a touch screen is fixedly installed on the outer surface of the control box, a release switch is fixedly installed on the outer surface of the control box and the release switch is connected to the electric push rod, and a distance measuring alarm mechanism is provided between the elevator and the control box.

[0014] By adopting the above technical solution, data can be adjusted and viewed through the touch screen, and the electric push rod can be controlled by the release switch. When the ton bag is lifted to a suitable height, the release switch can be used to remotely push the unhooker to open and drop the ton bag, further improving the convenience and safety of use.

[0015] Preferably, the ranging alarm mechanism includes: a distance detection sensor, which is fixedly installed on one side of the outer surface of the elevator, and the elevator and the distance detection sensor are installed vertically, and the distance detection sensor is designed to be perpendicular to the steel plate; an alarm indicator is fixedly installed on the outer surface of the control box; a control switch is fixedly installed on the outer surface of the control box, and the control switch is connected to the elevator.

[0016] By adopting the above technical solution, the height of the ton bag located below can be monitored by a distance detection sensor. The touch screen can be used to adjust and set the value of the distance detection sensor. After the ton bag moves to the set height by controlling the rotation of the elevator via a control switch, an alarm prompts the test personnel to release the ton bag for testing once the specified height has been reached. This ensures that all ton bags are at the same height during testing, reducing inaccurate measurement data caused by inconsistent heights during testing.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the ton bag drop test device: 1. After placing the ton bag on the steel plate, the release device can be opened, and the sling of the ton bag can be inserted into the opening of the release device. Then, the release device can be closed and returned to its position. Afterward, by rotating the elevator and using the lifting pulley, the release device and the ton bag can be lifted to the specified height at a uniform speed. Then, the release device can be pushed by the electric push rod to open and release the ton bag, allowing workers to stay away from the ton bag during the test and to lift the ton bag stably, which greatly improves the convenience and safety of the test. 2. Secondly, by flexibly placing the warning posts and coordinating the extension and retraction of the isolation belts, the area of ​​the steel plate can be isolated during testing. At the same time, by using microswitches, the control box cannot be operated by the control switch or release switch when any retraction isolation belt is not closed. This prevents the elevator from operating when the operator hangs and operates the ton bag on the steel plate, greatly improving the safety during use. 3. By installing a distance detection sensor, the distance between the elevator and the ton bag can be monitored. The touch screen can be used to adjust the distance detection sensor value. Once the ton bag rises to the set value, an alarm will sound to alert the experimenter that the ton bag has reached the set height. The release switch can be used to open the release mechanism and release the ton bag, allowing the test height of the ton bag to be adjusted so that the drop height of the ton bag is the same for each measurement, thus obtaining accurate measurement values. This also provides reminders to the experimenter, greatly improving the accuracy and convenience of data acquisition. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6This utility model provides a technical solution: a ton bag drop test device, including a crossbeam 1, a lifting platform 2 placed against the outer surface of the crossbeam 1, and waist-shaped holes evenly distributed on the side of the lifting platform 2 near the crossbeam 1. Fixing rods 3 are inserted through the waist-shaped holes of the lifting platform 2 and fixed to the lifting platform 2 with nuts. The outer surface of the fixing rods 3 is in contact with the outer surface of the crossbeam 1. A power supply box 4 is fixedly installed on the outer surface of the crossbeam 1 near the lifting platform 2. A power supply box 4 is fixedly installed on the ground below the crossbeam 1. The elevator 2 is equipped with a control box 6. The steel cable of the elevator 2 is threaded through a lifting trolley 7, which is located below the elevator 2. A U-shaped ring 8 is rotatably installed on the outer surface of the lifting trolley 7, and the U-shaped ring 8 is connected to the lifting trolley 7 by bolts. A release device 9 is rotatably installed on the outer surface of the U-shaped ring 8, and the outer surface of the release device 9 is in contact with the outer surface of the U-shaped ring 8. An electric push rod 10 is fixedly installed on the side surface of the release device 9, and the output end of the electric push rod 10 is in contact with the outer surface of the release device 9.

[0022] Initially, during use, simply pass the fixing rod 3 through the crossbeam 1 and fix the elevator 2, fix the power box 4 to the outer surface of the crossbeam 1, and fix the control box 6 to the ground to complete the basic installation. When measuring the ton bag, simply place the ton bag on the outer surface of the steel plate 5 using a forklift, and place the ton bag inside the positioning warning tape 11. Then, control the elevator 2 to operate via the control switch 17, allowing the lifting trolley 7 and the release device 9 to descend. After that, place the ton bag's sling into the release device 9, and then control the elevator 2 to lift the ton bag and move it to the required testing height. Then, operate the electric push rod 10 via the release switch 18 to open the release device 9 and release the ton bag for testing, reducing the risk of injury to experimental personnel and allowing experimental personnel to conduct experiments away from the ton bag, greatly improving the safety of the experimental device during use.

[0023] A steel plate 5 is fixedly embedded in the ground below the crossbeam 1, and the steel plate 5 protrudes from the ground. The steel plate 5 is located below the hook release device 9, and the hook release device 9 is located in the center of the steel plate 5. A positioning warning tape 11 is pasted and fixed on the outer surface of the steel plate 5. The positioning warning tape 11 is the same size as the ton bag. The positioning warning tape 11 forms a square frame, and the geometric center of the square frame formed by the positioning warning tape 11 coincides with the installation center of the hook release device 9.

[0024] Secondly, the steel plate 5 is 8cm thick, and when the ton bag falls, it will contact the surface of the steel plate 5, so that the ton bag will not cause inaccurate measurement data due to uneven ground. At the same time, it can ensure that the ground will not be damaged by impact after multiple tests. In addition, the use of positioning warning tape 11 allows the ton bag to be placed and positioned on the steel plate 5. When the elevator 2 rotates and lifts the ton bag, the ton bag will not shake or collide with foreign objects due to excessive displacement, further improving the safety during use and the accuracy of measurement data.

[0025] Warning posts 12 are placed around the ground around the steel plate 5, and a telescopic isolation belt 13 is provided at one end of the warning post 12. The telescopic isolation belt 13 is inserted into another warning post 12. A micro switch 14 is fixedly installed on the outer surface of the warning post 12, and the outer surface of the micro switch 14 is in contact with the outer surface of the telescopic isolation belt 13. The micro switch 14 is connected to the control box 6.

[0026] Furthermore, the steel plate 5 can be surrounded and isolated by the warning post 12 and the telescopic isolation belt 13. The micro switch 14 monitors whether the telescopic isolation belt 13 is installed and in use, so that irrelevant personnel can be restricted and blocked outside the steel plate 5 during the test. After the experimental personnel hang and adjust the ton bag inside the steel plate 5, the telescopic isolation belt 13 is inserted back, which further improves the safety of the experimental device during use.

[0027] A touch screen display 15 is fixedly installed on the outer surface of the control box 6. A release switch 18 is fixedly installed on the outer surface of the control box 6 and is connected to the electric push rod 10. A distance measuring alarm mechanism is provided between the elevator 2 and the control box 6. The distance measuring alarm mechanism includes a distance detection sensor 16, which is fixedly installed on one side of the outer surface of the elevator 2. The elevator 2 and the distance detection sensor 16 are installed vertically, and the distance detection sensor 16 is designed to be perpendicular to the steel plate 5. An alarm indicator 19 is fixedly installed on the outer surface of the control box 6. A control switch 17 is fixedly installed on the outer surface of the control box 6 and is connected to the elevator 2.

[0028] Furthermore, when adjusting the height of the ton bag measurement according to requirements, the detection distance of the distance detection sensor 16 can be adjusted through the touch screen 15, so that the set data of the distance detection sensor 16 can be adjusted. This allows the elevator 2 to monitor the lifting trolley 7 as it rises. Once the ton bag reaches the set height, the alarm prompt 19 can alert and prompt the testing personnel, informing them that the ton bag can be released by the unhooking device 9 when the specified height is reached. This ensures that the height of the ton bag is the same each time it is tested, greatly reducing data errors during the test of the experimental device.

[0029] Working principle: When testing the ton bag, the ton bag is first placed on the steel plate 5 by the positioning warning tape 11. Then, the release device 9 is assembled under the lifting trolley 7 through the U-ring 8. Next, the telescopic isolation belt 13 is opened and the lifting lug of the ton bag is inserted into the release device 9 and reset. Then, the lifting platform 2 can be moved by the control switch 17. The distance detection sensor 16 monitors the rising distance of the ton bag. When the ton bag moves to the required height, the alarm prompt 19 will prompt the operator without measurement. Then, the release switch 18 is pressed to allow the electric push rod 10 to be pushed out, so that the release device 9 can be opened and the ton bag can be released, thus completing the drop test of the ton bag.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
