Description

Technical Field

[0001] This utility model belongs to the field of safety shoe technology, specifically, it relates to a test device for anti-slip safety shoe steel toe impact resistance. Background Technology

[0002] In the toe cap manufacturing process of safety shoes, steel toes are used for protection to improve safety. After the steel toes are manufactured, they need to be subjected to an impact resistance test to determine whether the production quality is up to standard.

[0003] Chinese Patent Publication No. CN222074633U discloses a test device for the impact resistance of steel toe caps on work shoes. The device includes a base and test components. The test components include a support, an impact unit, two electronic slide rails, two first motors, two first cylinders, two first clamping blocks, a rotation adjustment unit, and two clamping and fixing units. The impact unit is activated to perform an impact resistance test. After the test, the first cylinders are activated, causing the first clamping blocks to clamp the steel toe caps. Simultaneously, the electronic slide rails are activated, causing the steel toe caps to move upwards. Then, the motors are activated, causing the first cylinders to rotate, causing the steel toe caps to flip and be repositioned. The steel head is placed on a rotating adjustment unit, which also drives the steel head to rotate. Then, it is clamped by the first clamping block and flipped for adjustment, thereby allowing for impact resistance testing of both ends and sides of the steel head. The existing technology tests the protective effect of the steel head by dropping it. However, after testing, the deformation of the steel head on some anti-slip safety shoes can affect the overall shape of the shoe, thus affecting the anti-slip effect of the sole. Sometimes, the deformation of the internal steel head cannot be observed with the naked eye, leading to the mistaken belief that the shoe is normal. As a result, the shoes are still used even after the anti-slip effect has been reduced, thus creating a safety hazard.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a test device for anti-slip work shoes steel toe impact resistance, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-5 As shown in the figure, this embodiment provides a test device for anti-slip work shoes steel toe impact resistance, including: a workbench 1.

[0030] like Figure 1-3As shown, in this embodiment, a support plate 2 is provided at the center of the workbench 1, and brackets 3 are provided at the four corners of the workbench 1. A crossbeam 4 is provided horizontally at the top of the bracket 3, and a base 5 is sleeved at the center of the crossbeam 4. A connecting plate 6 is provided at the bottom of the base 5, and a hydraulic cylinder 7 is installed at the bottom of the connecting plate 6. A hydraulic rod 8 is provided at the bottom of the hydraulic cylinder 7, and a mounting seat 9 is provided at the bottom of the hydraulic rod 8. A pressure head 10 is installed at the bottom of the mounting seat 9. Adjustment frames 15 are provided on both sides of the support plate 2 at the top of the workbench 1. A base plate 13 is provided below the workbench 1, and a support column 1 is provided at the bottom of the support plate 2. 4; Among them, the bracket 3 connects the bottom base plate 13, the middle workbench 1 and the top crossbeam 4, and the three are horizontal. The base 5 is sleeved on the crossbeam 4 and fixed downwards. The four hydraulic cylinders 7 face downwards and are fixed at the bottom on the connecting plate 6, located at the four corners of the connecting plate 6. At the same time, the hydraulic rod 8 is controlled to move to drive the mounting seat 9 to move up and down. The mounting seat 9 remains horizontal. A pressure head 10 is installed at the center of the mounting seat 9. When the mounting seat 9 is lowered, the pressure head 10 hits the safety shoe on the support plate 2 to simulate the process of the safety shoe being hit by a heavy object. The quality of the steel head is detected by observing whether the steel head is deformed.

[0031] like Figure 4 , 5 As shown, the adjusting frame 15 in this embodiment is provided with a slider 16 inside. A pressure rod 17 is longitudinally rotatably installed at the center of the slider 106. A pressure ring 19 is provided at the front end of the pressure rod 17 facing the support plate 2. An adjusting screw 18 is vertically installed at the center of the support column 14. The pressure rod 17 fits against the safety shoe through the front pressure ring 19. The pressure rod 17 passes through the threaded hole on the slider 16. Rotating the pressure rod 17 pushes it towards the safety shoe on the support plate 2 through the engagement of the surface thread and the internal thread of the threaded hole, thereby clamping and releasing the safety shoe. At the same time, the adjusting screw 18 connected to the top of the slider 16 passes through the threaded hole at the top of the adjusting frame 15. By rotating the adjusting screw 18, the slider 16 is pulled upward, thereby raising the pressure rod 17 to fix some higher safety shoes.

[0032] like Figure 5 As shown, in this embodiment, a top ring 1601 is fixedly connected to the top of the slider 16, and a bottom ring 1801 is fixedly connected to the bottom of the adjusting screw 18. The bottom ring 1801 on the adjusting screw 18 is embedded in the top ring 1601. When the adjusting screw 18 rotates, the bottom ring 1801 rotates with the top ring 1601. When it moves upward, the bottom ring 1801 pulls the top ring 1601 to lift the slider 16, thereby adjusting the height of the slider 16 within the adjusting frame 15.

[0033] like Figure 3As shown, in this embodiment, a pivot 201 is installed through one end of the support plate 2. In the previous test of the steel head, since the steel head is installed inside the shoe, it may undergo unobservable deformation, which further affects the sole of the shoe and weakens the anti-slip effect. Therefore, it is necessary to test the anti-slip performance. The support plate 2 is placed in the rectangular hole opened in the center of the workbench 1, and the bottom is supported by the support column 14. At the same time, the pivot 201 is installed through one end, and the two ends of the pivot 201 are installed on the workbench 1. In this way, the support plate 2 can be tilted upward around the pivot 201 as the axis, thereby lifting the work shoe on the support plate 2. This causes the weight of the work shoe and the supporting force of the support plate 2 to be tilted at an angle. The work shoe is supported by the friction between the bottom and the support plate 2. The better the anti-slip effect of the shoe, the greater this friction. As the angle of tilt between the support plate 2 and the workbench 1 increases, the required friction also increases. By observing whether the shoe moves on the support plate 2, it can be confirmed whether the impact of the steel head has affected the anti-slip effect.

[0034] like Figure 2 , 3 As shown, in this embodiment, the support column 14 is provided with a lifting motor 20 in the opposite direction to the rotating shaft 201. The top of the lifting motor 20 is provided with a lifting rod 21, and the top of the lifting rod 21 is provided with a roller 22. The lifting motor 20 controls the lifting rod 21 to move upward, and the roller 22 is in contact with the bottom of the support plate 2 to lift the support plate 2. The roller 22 and the support plate 2 reduce friction through rolling friction to facilitate lifting, so that the angle between the support plate 2 and the worktable 1 can be better controlled.

[0035] like Figure 3 As shown, the top of the support plate 2 in this embodiment is provided with an anti-slip pad 202; wherein, the anti-slip pad 202 is used to simulate the bottom environment, and the anti-slip pad 202 can be removed and replaced, thereby simulating the friction between work shoes and different ground surfaces, making the measured effect more realistic.

[0036] like Figure 1 , 2 As shown, in this embodiment, the bracket 3 is provided with tripods 11 at both ends of the crossbeam 4, and the tripods 11 are provided with connecting rods 12 on the top of the base 5; wherein, the center of the tripods 11 is connected to the base 5 through the connecting rods 12, so that the base 5 is supported by the crossbeam 4 and the connecting rods 12, making the whole more stable.

[0037] Working principle: Place the complete safety shoe on the support plate 2, align the front steel head with the center of the support plate 2, install the pressure head 10, rotate the pressure rod 17 and the adjusting screw 18 to adjust the position of the pressure ring 19, and finally the pressure rings 19 at both ends clamp the safety shoe. The top hydraulic cylinder 7 is activated and the pressure head 10 is lowered through the hydraulic rod 8 to simulate the safety shoe being hit by a heavy object. Observe whether the safety shoe is deformed. Then rotate the pressure rod 17 in the opposite direction to move away from the support plate 2. The lifting motor 20 raises the lifting rod 21, and the roller 22 lifts the support plate 2 to rotate around the pivot 201, so that an angle appears between the support plate 2 and the worktable 1 to test the friction between the safety shoe and the support plate 2, that is, whether the anti-slip effect is reduced.
