Description

Technical Field

[0001] The present invention relates to the technical field of shoe toe detection, in particular to a labor protection shoe toe compression resistance detection device with a protective function. Background Art

[0002] Labor protection shoes (safety shoes) are specialized footwear designed to protect workers' feet from mechanical impact, punctures, static electricity, chemical corrosion, and other hazards in the workplace. Widely used in high-risk industries such as construction, mining, petrochemicals, and machinery manufacturing, they are a crucial component of occupational safety systems. During the production and quality testing of labor protection shoes, the compression and impact resistance of the toe box are crucial indicators of their protective capabilities.

[0003] Traditional testing methods usually use a fixed-weight impact hammer to perform a single force test. This lacks the ability to adjust the impact force and is unable to simulate the impact conditions of different intensities encountered in actual use. This results in incomplete test results and makes it difficult to accurately evaluate the protective performance of the toe box under different force conditions. Summary of the Invention

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1-7 As shown, the embodiment of the present invention provides a labor protection shoe toe pressure resistance detection device with a protective function, comprising:

[0033] A workbench 1 is provided with a bracket 11 fixedly arranged at the bottom of the workbench 1, the bracket 11 is used to support the workbench 1, a mounting platform 12 is fixedly arranged on the workbench 1, a clamping plate 13 is fixedly arranged on the mounting platform 12, and the clamping plate 13 is used to limit the toe of the labor protection shoe. The clamping plate 13 can be pressed against the inner side of the toe of the labor protection shoe to thereby clamp the toe of the labor protection shoe.

[0034] The striking assembly 2 includes a shaft 22, a cradle 24, and a striking hammer 210. The workbench 1 is fixed to two side panels 21. The shaft 22 extends through the two side panels 21 for rotational connection. The shaft 22 is movably positioned through the cradle 24, allowing the cradle 24 to rotate freely about the shaft 22. The striking hammer 210 is mounted at one end of the cradle 24 and is used to test the compression resistance of the toe box.

[0035] The workbench 1 is provided with a driving assembly for driving the cradle 24 to swing. The driving assembly includes a motor 23, an L-shaped plate 25, a shaft 27 and a roller 29. The bending part of the L-shaped plate 25 is hingedly connected to one end of the cradle 24 (such as Figure 3 As shown, the shorter end of the L-shaped plate 25 abuts against the cradle 24, thereby allowing the longer end of the L-shaped plate 25 to rotate upward but not downward).

[0036] Two side panels 26 are fixedly provided on the workbench 1, and a shaft 27 passes through the two side panels 26 and is rotatably connected. The motor 23 is fixed on the side panel 26, and one end of the shaft 27 is fixed on the output end of the motor 23. A movable plate 28 is fixed on the shaft 27, and a roller 29 is rotatably connected to the outer end of the movable plate 28.

[0037] Motor 23 drives movable plate 28 and roller 29 to rotate counterclockwise. When roller 29 contacts L-shaped plate 25, it squeezes and pries cradle 24, lifting hammer 210. When roller 29 disengages, hammer 210 falls freely and strikes the toe of the shoe. This cycle repeats multiple times, completing the toe impact test.

[0038] The counterweight assembly 3 comprises a threaded rod 31 and a counterweight 32. The threaded rod 31 is rotatably connected to the cradle 24. The threaded rod 31 extends through the counterweight 32 and is threadedly connected thereto, so that rotation of the threaded rod 31 drives the counterweight 32. A guide rod 35 is fixedly mounted within the cradle 24 and slides through the counterweight 32, guiding the counterweight 32. A bevel gear 33 is fixedly mounted on the shaft 22. A bevel gear 34 is fixedly mounted on one end of the threaded rod 31. The bevel gear 33 meshes with the bevel gear 34, allowing the shaft 22 to drive the threaded rod 31 to rotate via the bevel gears 33 and 34.

[0039] Pulleys 36 are fixedly provided on the shaft 1 22 and the shaft 2 27 , and a belt 37 is sleeved on the two pulleys 36 so that transmission can be carried out between the two pulleys 36 through the belt 37 .

[0040] During the impact resistance test, shaft 2 27 drives threaded rod 1 31 to rotate through belt 37, shaft 1 22, bevel gear 1 33 and bevel gear 2 34, so that the counterweight 32 gradually moves away from the hammer 210. The change in the position of the counterweight 32 gradually increases the impact force, thereby realizing the impact resistance test of the toe under different impact forces (when the counterweight 32 is closer to the hammer 210, its gravity arm is shortened, resulting in a decrease in driving torque; at the same time, the mass distribution is away from shaft 1 22, which increases the moment of inertia and further reduces the angular acceleration. Since the terminal velocity of the hammer 210 is proportional to the angular acceleration, the final impact force is weakened. Therefore, at a fixed release height, the counterweight 32 approaches the hammer 210 to reduce the impact force; the counterweight 32 moves away from the hammer 210, which increases the torque and reduces the moment of inertia, thereby enhancing the impact force).

[0041] It also includes a rotating component 4, which includes a round rod 42, a turntable 43, a push rod 45 and an extrusion column 46. A partition 41 is fixedly set in the cradle 24. The round rod 42 and the threaded rod 31 are respectively rotatably connected on both sides of the partition 41. The round rod 42 passes through one end of the cradle 24 and is rotatably connected. The percussion hammer 210 is fixedly set at the outer end of the round rod 42. A plurality of conical blocks 414 are fixed on the percussion hammer 210. The plurality of conical blocks 414 are arranged in sequence according to the size of the sharpness of the outer end, and the sharpness gradually increases.

[0042] A turntable 43 is fixedly mounted on a round rod 42 and is provided with a plurality of inclined slots 44 evenly distributed around the circumference. A push rod 45 slides through the partition 41, and a compression column 46 is hingedly connected to the push rod 45. A torsion spring 1 is provided at the hinged connection between the compression column 46 and the push rod 45. A limit column 47 is fixedly mounted on the compression column 46, and the limit column 47 is arranged to abut against the push rod 45. The torsion spring 1 can drive the compression column 46 to tilt to one side, and the limit column 47 is pressed against the push rod 45 to lock it in place. After the compression column 46 rotates, the torsion spring 1 can drive the compression column 46 to return to its original position.

[0043] When the counterweight 32 returns to its leftmost position, it pushes the push rod 45, driving the squeeze column 46 to squeeze the chute 44, causing the turntable 43 to rotate. The turntable 43 then rotates the hammer 210, moving the conical block 1 414 to its lowest position. This allows the toe cap to be tested for puncture resistance. This cycle allows the toe cap 1 414 to be switched to different sharpnesses, allowing comprehensive testing of the puncture resistance of different toe cap strengths.

[0044] The turntable 43 is provided with a fixing assembly comprising a T-shaped plate 49, a clamping post 412, a second guide rod 410, a first spring 411, and a top post 48. The second guide rod 410 is fixedly mounted within the cradle 24 and slides through the T-shaped plate 49, guiding the T-shaped plate 49. The clamping post 412 is fixedly mounted on one side of the T-shaped plate 49. The outer side of the turntable 43 is provided with a plurality of clamping holes 413, evenly distributed around the circumference. The clamping post 412 can be inserted into the clamping holes 413, thereby securing the turntable 43. The first spring 411 is fixedly mounted on the other side of the T-shaped plate 49, and the other end of the first spring 411 is fixedly mounted on the inner side of the cradle 24, allowing the T-shaped plate 49 to be elastically connected via the first spring 411. The top column 48 is fixedly disposed on the push rod 45 , and the push rod 45 is disposed against the T-shaped plate 49 , so that the push rod 45 can push the T-shaped plate 49 through the top column 48 .

[0045] Before the squeeze post 46 contacts the chute 44, the push post 48 pushes the T-shaped plate 49 and compresses the spring 1 411, causing the locking post 412 to disengage the locking hole 413, releasing the turntable 43 from its securement and allowing it to rotate. When the counterweight 32 moves right, the spring 1 411 pushes the T-shaped plate 49 back into place, causing the locking post 412 to engage the corresponding locking hole 413, securing the turntable 43. Simultaneously, the T-shaped plate 49, via the push post 48, drives the squeeze post 46 of the push rod 45 back into place. (As the squeeze post 46 returns to its original position, the chute 44 pushes the squeeze post 46 to rotate. After the two separate, the squeeze post 46 is finally reset by the action of the torsion spring 1.)

[0046] It also includes a side detection component 5, which includes an L-shaped lifting plate 51, an L-shaped long rod 53, a second spring 55, a movable plate 56, a second conical block 58 and a vertical rod 59. The L-shaped long rod 53 is slidably arranged through the L-shaped lifting plate 51, and a mounting block 54 is fixedly arranged on the L-shaped long rod 53. The two ends of the second spring 55 are respectively fixedly arranged on the mounting block 54 and the L-shaped lifting plate 51, so that the L-shaped long rod 53 can be elastically connected to the L-shaped lifting plate 51 through the second spring 55.

[0047] The movable plate 56 is connected to one end of the L-shaped long rod 53, allowing the L-shaped long rod 53 to drive the movable plate 56 to move. A second conical block 58 is fixed to the outer end of the movable plate 56 and is used for pressure resistance testing on the side of the shoe toe. A vertical rod 59 is hingedly connected to the L-shaped long rod 53. The side of the vertical rod 59 is arranged to abut the inner side of the L-shaped long rod 53, so that when the roller 29 squeezes the vertical rod 59, the pressure resistance drives the L-shaped long rod 53 to move. A second torsion spring is installed at the hinge between the vertical rod 59 and the L-shaped long rod 53, so that after the vertical rod 59 rotates, the second torsion spring compresses and drives the vertical rod 59 to return to its original position.

[0048] A guide rod 3 52 and a guide rod 4 57 are fixedly provided on the workbench 1. The guide rod 3 52 is slidably provided through the L-shaped lifting plate 51 and guides the L-shaped lifting plate 51. The guide rod 4 57 is slidably provided through the movable plate 56 and guides the movable plate 56.

[0049] The rotating roller 29 pushes the L-shaped rod 53 against pressure, compressing the second spring 55, which in turn drives the second conical block 58 away from the toe. When the roller 29 disengages the vertical rod 59, the second spring 55 quickly resets the L-shaped rod 53, causing the second conical block 58 to strike the side of the toe, thus achieving puncture resistance testing of the side of the toe.

[0050] The workbench 1 further includes an adjustment assembly 6, which includes a transmission rod 61, a third bevel gear 62, a second threaded rod 63, an adjustment plate 64, and an adjustment column 66. The third bevel gear 62 and the second threaded rod 63 are fixedly mounted at both ends of the transmission rod 61. The third bevel gear 62 is meshed with the first bevel gear 33, allowing the first shaft 22 to rotate the second threaded rod 63 via the third bevel gear 62 and the first bevel gear 33. The second threaded rod 63 is rotatably connected to the workbench 1. The second threaded rod 63 extends through the L-shaped lifting plate 51 and is threadedly connected thereto, allowing the rotating second threaded rod 63 to slowly raise and lower the L-shaped lifting plate 51.

[0051] An adjustment plate 64 is fixedly mounted on the bottom of the movable plate 56. An adjustment hole 65 is formed through the adjustment plate 64. An adjustment post 66 is movably mounted through the adjustment hole 65, allowing the adjustment post 66 to move freely within the adjustment hole 65. Limiting plates 67 are fixedly mounted on both ends of the adjustment post 66. One of the limiting plates 67 is fixedly mounted on the L-shaped long rod 53. The limiting plates 67 limit the adjustment post 66, ensuring that the adjustment post 66 is retained within the adjustment hole 65.

[0052] During testing, the shaft rod 1 22 is pressed against the pressure to drive the threaded rod 2 63 to rotate, driving the L-shaped lifting plate 51 and the vertical rod 59 to move upward, thereby increasing the displacement of the L-shaped long rod 53 and increasing the impact force of the conical block 2 58, thereby realizing pressure testing of different intensities on the side of the shoe toe.

[0053] The detailed working process of the present invention is as follows:

[0054] During testing, the motor 23 drives the movable plate 28 and roller 29 counterclockwise via the second shaft 27. When the roller 29 rotates until it contacts the L-shaped plate 25, it squeezes it, thereby prying the cradle 24 and lifting the other end, which in turn raises the hammer 210. As the roller 29 continues to rotate until it separates from the L-shaped plate 25, the hammer 210, no longer supported, falls rapidly under the action of gravity, completing the tapping action on the toe of the shoe. This repetitive cycle, with multiple tapping operations, effectively tests the toe's impact resistance.

[0055] 2. Simultaneously, shaft 27 drives shaft 1 22 via pulley 36 and belt 37, which in turn drives threaded rod 1 31 via bevel gear 1 33 and bevel gear 2 34. The rotation of threaded rod 1 31 causes counterweight 32 to slowly move away from hammer 210. As the position of counterweight 32 changes, the impact force of hammer 210 gradually increases, thereby enabling the impact resistance of the shoe toe to be tested under different impact forces.

[0056] 3. When the counterweight 32 moves to its leftmost position, it pushes the push rod 45. Push rod 45 pushes T-plate 49 via top post 48, compressing spring 1 411, driving the locking post 412 to separate from the locking hole 413, thereby releasing the fixed state of the turntable 43 and allowing it to rotate. Push rod 45 then drives the squeezing post 46 to squeeze the corresponding chute 44, causing the turntable 43 to rotate. The turntable 43, via the round rod 42, drives the hammer 210 to rotate, rotating the conical block 1 414 to its lowest position. Then, when the counterweight 32 moves to the right, spring 1 411 drives the T-plate 49 to return, causing the locking post 412 to engage the corresponding locking hole 413, securing the turntable 43. Simultaneously, the T-plate 49 pushes the squeezing post 46 of the push rod 45 to return to its original position via top post 48. The puncture resistance of the toe cap can then be tested. By cyclically operating the mechanism, the conical blocks 414 with different sharpnesses can be switched in sequence, thereby achieving a comprehensive test of the puncture resistance of shoe toes with different strengths.

[0057] 4. At the same time, when the roller 29 rotates to contact the vertical rod 59, it will exert an extrusion effect on it, thereby pushing the L-shaped long rod 53 to move and squeezing the spring 2 55. The L-shaped long rod 53 drives the conical block 2 58 to move away from the toe through the movable plate 56. As the roller 29 continues to rotate until it separates from the vertical rod 59, the L-shaped long rod 53 is quickly reset under the action of the spring 2 55, thereby driving the conical block 2 58 to quickly reset and hit the side of the toe, thereby testing the puncture resistance of the side of the toe.

[0058] 5. During the puncture resistance test of the side of the shoe toe, the shaft rod 1 22 drives the threaded rod 2 63 to rotate through the bevel gear 3 62 and the bevel gear 1 33, thereby driving the L-shaped lifting plate 51 to rise slowly. As the L-shaped lifting plate 51 rises, the L-shaped long rod 53 connected to it will push the vertical rod 59 to move upward synchronously. When the vertical rod 59 rises, the extrusion point applied by the roller 29 to it will gradually move downward, resulting in an increase in the displacement of the vertical rod 59 and the L-shaped long rod 53. When the conical block 2 58 is released, the distance between it and the shoe toe will be larger, and the final impact force will be stronger, thereby realizing pressure resistance testing of the side of the shoe toe with different intensities.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
