Description

Technical Field

[0001] The invention relates to the technical field of lighting equipment detection, and in particular to a lighting equipment durability detection device. Background Art

[0002] Lighting equipment mainly converts electrical energy, chemical energy and other energies into light energy to provide lighting effects. Lighting equipment can be divided into indoor lighting equipment, outdoor lighting equipment, industrial lighting equipment, etc. according to the usage scenario. Among them, the mining headlamp in industrial lighting equipment generally includes a lamp holder, a battery, a connecting socket and a control part. The connecting socket is bound to the miner's head through a headband, or fixed to the helmet by bolts. The lamp holder is hinged to the connecting socket to facilitate the adjustment of the angle of the lamp holder.

[0003] In order to ensure the safety of miners, reduce the replacement of mining headlamps and improve production efficiency, it is necessary to test the durability of mining headlamps. The vibration tester is used to simulate the vibration conditions that mining headlamps may be subjected to in mines, such as vibrations caused by equipment operation and personnel walking. These vibrations will affect the stability of circuit boards and wire connections inside mining headlamps, which will ultimately affect the illumination of mining headlamps. The vibration tester can be used to test the durability of mining headlamps under vibration.

[0004] When a mining headlamp is actually used, it will not only vibrate vertically up and down, but also rotate left and right and shake up and down. The existing vibration testing machine can only perform vibration detection on the mining headlamp in one direction, and thus cannot accurately simulate the actual use scenario of the mining headlamp, which makes the detection result too one-sided. In addition, in the actual use of the mining headlamp, the lamp holder and the connecting socket will be adjusted to a certain angle as required, and it is necessary to maintain this angle during use. However, the angle may change under the action of vibration, and the change may be small. The existing vibration testing machine can only vibrate the mining headlamp, and cannot perform real-time detection of the angle between the lamp holder and the connecting socket during vibration. Manual observation of the lamp holder and the connecting socket is required, and manual detection accuracy is low. Summary of the invention

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0033] See also Figure 1 A lighting equipment durability detection device includes a base 1, an installation frame 3 is slidably arranged on the upper part of the base 1 through a guide column 2 in a vertical direction, and a reversing mechanism 4 for rotating the headlight left and right and shaking it up and down is arranged on the installation frame 3.

[0034] When it is necessary to conduct a durability test on the mining headlamp, the operator first installs the connecting socket of the mining headlamp inside the reversing mechanism 4 in a detachable manner, and then vibrates the mining headlamp up and down through the reversing mechanism 4, and at the same time, turns the mining headlamp left and right and shakes it up and down, thereby simulating the actual use of the mining headlamp. While testing, the reversing mechanism 4 can also perform real-time testing on the angle between the connecting socket and the lamp head of the mining headlamp, thereby testing the firmness of the connection between the connecting socket and the lamp head.

[0035] See also Figure 1 , Figure 2 and Figure 3 The reversing mechanism 4 includes a shaking horizontal plate 41 which is evenly spaced along the vertical direction inside the mounting frame 3, and ear seat plates are symmetrically fixedly installed on the left and right sides of the shaking horizontal plate 41. The shaking horizontal plate 41 is rotatably connected to the vertical section of the mounting frame 3 through the ear seat plates thereon. Mounting plates 42 for fixing the connecting seat of the headlight are evenly spaced along the left and right directions on the shaking horizontal plate 41. A shaft rod is fixedly installed in the middle of the mounting plate 42. The mounting plate 42 is rotatably connected to the shaking horizontal plate 41 through the shaft rod inside it. A detection component 43 for real-time detection of the angle between the connecting seat part and the lamp holder part of the headlight is arranged on the front side of the mounting plate 42.

[0036] See also Figure 2 and Figure 3 The detection component 43 includes a fixed support plate 431 fixedly mounted on the upper front side of the mounting plate 42, a laser rangefinder 432 is slidably arranged on the fixed support plate 431 along its length direction, an adjusting screw 433 is rotatably arranged on the front part of the shell of the laser rangefinder 432, and the adjusting screw 433 is threadedly connected to the fixed support plate 431.

[0037] When the mining headlamp needs to be inspected, the operator first fixes the connecting socket of the mining headlamp on the front side of the mounting plate 42 by means of bolt connection, and then the operator rotates the lamp head of the mining headlamp so that there is a certain angle between the lamp head and the connecting socket, and then the operator manually rotates the adjusting screw 433, and the adjusting screw 433 drives the laser rangefinder 432 to adjust its position forward and backward, so that the lower part of the laser rangefinder 432 is directly above the lamp head of the mining headlamp, so that the laser rangefinder 432 can detect the position of the lamp head of the mining headlamp in real time.

[0038] Under the action of vibration, the connection stability between the lamp holder and the connecting socket of the mining headlamp in actual use can be judged by reading whether the change in the distance measurement value of the laser rangefinder 432 exceeds the specified range, and an accurate conclusion can be drawn.

[0039] See also Figure 1 , Figure 2 and Figure 3The reversing mechanism 4 also includes a rotating component 44 arranged on the rocking horizontal plate 41, and the rotating component 44 includes a swinging plate 441 fixedly mounted on the upper end of the shaft rod of the mounting plate 42, and a movable plate 442 is hinged on the lower side of the rear end of the swinging plate 441 on the mounting plate 42 connected to the same rocking horizontal plate 41, and a sliding block 443 slidably connected to it along the left and right directions is symmetrically arranged on the movable plate 442, and a fixed plug column 444 is symmetrically fixedly mounted on the rear side of the rocking horizontal plate 41, and the fixed plug column 444 is slidably connected to the sliding block 443 along the front and rear directions, and a pushing spring is arranged between the sliding block 443 and the rocking horizontal plate 41, and a pushing part 445 for pushing the movable plate 442 back and forth is arranged on the rocking horizontal plate 41.

[0040] See also Figure 2 , Figure 3 and Figure 4 The pushing part 445 includes a bracket plate 4451 which is respectively fixedly installed on the upper and lower sides of the shaking horizontal plate 41, and an execution motor 4452 is fixedly installed on the upper right part of the lower bracket plate 4451. A first rotating shaft 4453 is rotated together on the left part of the rear side of the upper and lower bracket plates 4451, and a second rotating shaft 4454 is rotated on the right part of the rear side of the upper bracket plate 4451. The lower end of the second rotating shaft 4454 is fixedly connected to the output shaft of the execution motor 4452, and a transmission gear 4455 is fixedly installed on the lower part of the second rotating shaft 4454 and the first rotating shaft 4453, and the transmission gears 4455 at two corresponding positions are meshed.

[0041] Continue reading Figure 2 , Figure 3 and Figure 4 A toggle rod 4456 is fixedly installed on the first rotating shaft 4453 and the second rotating shaft 4454. The toggle rod 4456 is facing to the right in the initial state. The two toggle rods 4456 at corresponding positions are arranged up and down. Two limit plates 4457 arranged left and right are fixedly installed on the rear side of the movable plate 442. The limit plates 4457 and the toggle rods 4456 at corresponding positions are in the same horizontal plane.

[0042] Continue reading Figure 2 , Figure 3 and Figure 4 A blocking plate 446 is symmetrically fixedly installed on the upper rear side of the shaking horizontal plate 41. When the left and right end surfaces of the moving plate 442 move to abut against the blocking plate 446 on the same side of its moving direction, the toggle rod 4456 disengages from the limit plate 4457 at the corresponding position.

[0043] When the position of the laser rangefinder 432 is adjusted, the execution motor 4452 is started, and the execution motor 4452 drives the second shaft 4454 to rotate clockwise (viewed from top to bottom), and the second shaft 4454 drives the transmission gear 4455 on the right to rotate, and the transmission gear 4455 on the right synchronously drives the transmission gear 4455 on the left to rotate in the opposite direction, and the transmission gear 4455 on the left drives the first shaft 4453 to rotate synchronously, so that the first shaft 4453 and the second shaft 4454 rotate synchronously in the opposite direction, and at the same time, the first shaft 4453 and the second shaft 4454 respectively drive the toggle rod 4456 thereon to rotate.

[0044] When the No. 2 rotating shaft 4454 drives the toggle rod 4456 thereon to rotate from toward the right side to toward the front side, the No. 1 rotating shaft 4453 drives the toggle rod 4456 thereon to rotate from toward the right side to toward the rear side. When the toggle rod 4456 on the No. 2 rotating shaft 4454 rotates forward, the toggle rod 4456 on the No. 2 rotating shaft 4454 contacts the right limiting plate 4457 and pushes it to the left, so that the right limiting plate 4457 drives the moving plate 442 to move to the left synchronously. When the moving plate 442 moves to the left, it drives the rear end of the swinging plate 441 connected thereto to rotate to the left. The swinging plate 441 drives the mounting plate 42 to rotate to the right through the shaft of the mounting plate 42, thereby causing the mounting plate 42 to drive the mining headlamp to rotate to the right.

[0045] When the movable plate 442 moves to the left, it is pulled forward by the swing plate 441, so that the movable plate 442 drives the sliding block 443 to move forward along the axial direction of the fixed plug 444, thereby causing the sliding block 443 to compress the push spring. When the movable plate 442 moves to the left and abuts against the blocking plate 446 on the left, the movable plate 442 is blocked by the blocking plate 446 and stops moving instantly, so that the mining headlamp can stop rotating instantly, thereby making the rotation of the mining headlamp more in line with the actual situation. At this time, the toggle rod 4456 on the second rotating shaft 4454 is out of contact with the limit plate 4457 on the right, and the push spring pushes the movable plate 442 back to the initial position through its own elastic force, thereby causing the mining headlamp to rotate to the left to the initial position.

[0046] Then the first rotating shaft 4453 drives the toggle rod 4456 thereon to rotate from the left side to the front side. Similarly, the toggle rod 4456 on the first rotating shaft 4453 drives the mining headlamp to rotate to the left by pushing the limiting plate 4457 on the left side, thereby repeatedly rotating the mining headlamp left and right.

[0047] See also Figure 1 , Figure 2 , Figure 5 and Figure 6, the commutation mechanism 4 further includes a rocking assembly 45 jointly arranged on the mounting frame 3 and the rocking cross plate 41. The rocking assembly 45 includes a connecting shaft fixedly connected to the right part of the ear seat plate on the right side of the rocking cross plate 41. One end of the connecting shaft rotatably passing through the right side surface of the mounting frame 3 is fixedly connected with a driven gear 451. A driving rack 452 is slidably arranged along the vertical direction at the rear part of the right side surface of the mounting frame 3. The driving rack 452 meshes with all the driven gears 451. An L-shaped plate 453 is arranged on the right side of the driving rack 452. The L-shaped plate 453 is fixedly connected with the driving rack 452 through a pin. A reciprocating screw 454 is rotatably arranged at the upper right part of the right side surface of the mounting frame 3. The reciprocating screw 454 is in threaded connection with the horizontal section of the L-shaped plate 453. A driving motor 455 is fixedly installed at the upper right part of the mounting frame 3. The output shaft of the driving motor 455 is fixedly connected with the reciprocating screw 454.

[0048] When it is necessary to shake the mining headlamp up and down at a constant speed, the operator fixes the L-shaped plate 453 and the driving rack 452 together through a pin. Then, the driving motor 455 is started. The driving motor 455 drives the reciprocating screw 454 to rotate. The reciprocating screw 454 drives the L-shaped plate 453 to move up and down at a constant speed in a reciprocating manner. The L-shaped plate 453 drives the driving rack 452 to move synchronously. The driving rack 452 drives the driven gears 451 to rotate back and forth. The driven gears 451 drive the rocking cross plate 41 to rock up and down through the connecting shaft of the rocking cross plate 41, and finally drive the mining headlamp on the mounting plate 42 to rock up and down at a constant speed, so that the rocking cross plate 41 drives the mining headlamp to rock up and down at a constant speed through the mounting plate 42.

[0049] Refer to Figure 2 , Figure 5 and Figure 6 , a spring telescopic rod is arranged between the lower part of the vertical section of the L-shaped plate 453 and the driving rack 452. A stop plate 456 is fixedly installed at the lower right part of the right side surface of the mounting frame 3. An L-shaped locking plate member 457 is slidably arranged along the front-back direction at the rear side of the right side surface of the mounting frame 3. A fixing column 458 is fixedly installed at the upper right part of the right side of the locking plate member 457. A triangular plate 459 that pushes the fixing column 458 backward is fixedly installed at the upper rear part of the L-shaped plate 453. An L-shaped pushing member 450 that pushes the fixing column 458 forward is fixedly installed at the middle rear part of the L-shaped plate 453.

[0050] Refer to Figure 5 and Figure 6 , a notch groove is formed at the left side of the middle part of the locking plate member 457. A C-shaped plate 4571 is slidably arranged along the front-back direction at the middle part of the right side surface of the mounting frame 3. The right side of the longitudinal section of the C-shaped plate 4571 is slidably connected with the notch groove of the locking plate member 457. A rotating screw 4572 is rotatably arranged at the rear side of the C-shaped plate 4571. The rotating screw 4572 is in threaded connection with the mounting frame 3.

[0051] It should be noted that, Figure 6The fixing plate threadedly connected to the rotating screw 4572 belongs to a part of the mounting frame 3.

[0052] In the initial state, the L-shaped plate 453 drives the driving rack 452 to move to the upper side of the horizontal section of the locking plate member 457 through the spring telescopic rod. When a quick shaking test of the mining headlamp is required, the operator pulls out the pin on the L-shaped plate 453, so that the L-shaped plate 453 is slidably connected to the driving rack 452. Then the operator manually rotates the rotating screw 4572, so that the rotating screw 4572 pushes the locking plate member 457 forward through the C-shaped plate 4571. Then the operator manually pushes the locking plate member 457 forward, so that the front side of the locking plate member 457 abuts against the rear side of the front lateral section of the C-shaped plate 4571, and at the same time, the horizontal section of the locking plate member 457 moves below the driving rack 452.

[0053] Subsequently, the driving motor 455 is started. The driving motor 455 drives the L-shaped plate 453 to move downward through the reciprocating screw 454. The L-shaped plate 453 drives the driving rack 452 to move downward through the spring telescopic rod until it abuts against the horizontal section of the locking plate member 457, so that the locking plate member 457 blocks the driving rack 452 from moving downward. At the same time, the L-shaped plate 453 continues to move downward and compresses the spring telescopic rod, and the L-shaped plate 453 drives the triangular plate 459 thereon to move downward synchronously.

[0054] When the triangular plate 459 moves downward to the position of the fixed column 458, the triangular plate 459 pushes the fixed column 458 backward through the inclined surface thereon, so that the fixed column 458 drives the locking plate member 457 to move backward synchronously, so that the rear side of the locking plate member 457 abuts against the front side of the rear lateral section of the C-shaped plate 4571. At this time, the horizontal section of the locking plate member 457 completely moves to the rear side of the driving rack 452, and then the spring telescopic rod instantaneously pushes the driving rack 452 downward through its own elastic force. The driving rack 452 drives the mining headlamp to quickly shake upward through the shaking cross plate 41.

[0055] When the spring telescopic rod pushes the driving rack 452 downward through its own elastic force until it abuts against the stop plate 456, the driving rack 452 is blocked by the stop plate 456 and instantaneously stops moving, so that the mining headlamp quickly shakes upward and then instantaneously stops. Subsequently, the reciprocating screw 454 drives the L-shaped plate 453 to move upward. When the L-shaped plate 453 drives the driving rack 452 to move upward to the upper part of the horizontal section of the locking plate member 457 through the spring telescopic rod, the L-shaped plate 453 drives the pusher 450 to contact the fixed column 458, so that the inclined surface on the upper part of the vertical section of the pusher 450 pushes the fixed column 458 forward. The fixed column 458 drives the front side of the locking plate member 457 to abut against the rear side of the front lateral section of the C-shaped plate 4571 again, and at the same time, the driving rack 452 drives the mining headlamp to shake downward.

[0056] See also Figure 1 and Figure 7 The reversing mechanism 4 also includes a vibration component 46 arranged on the base 1. The vibration component 46 includes a positioning plate 461 arranged on the lower right side of the base 1 by sliding up and down through a guide rod. A rotating motor 462 is fixedly installed at the lower part of the positioning plate 461, and a lifting plate 463 is fixedly installed at the lower end of the guide column 2. A return spring is arranged between the lower part of the mounting frame 3 and the base 1. A pushing cam 464 is fixedly installed on the output shaft of the rotating motor 462. The pushing cam 464 is located on the upper side of the lifting plate 463. A hydraulic push rod 465 is fixedly installed on the upper right side of the base 1, and the telescopic section of the hydraulic push rod 465 is fixedly connected to the positioning plate 461.

[0057] When it is necessary to vibrate the mining headlamp up and down, start the rotating motor 462, which drives the pushing cam 464 to rotate, so that the pushing cam 464 pushes the lifting plate 463 downward, and the lifting plate 463 drives the installation frame 3 to move downward through the guide column 2. The installation frame 3 drives all the mining headlamps to move downward synchronously by shaking the cross plate 41, and at the same time compresses the return spring of the installation frame 3.

[0058] When the pushing stroke of the pushing cam 464 rotates to the upper side, the return spring pushes the mounting frame 3 upward by its own elastic force, so that all the mining headlamps move upward synchronously, thereby repeatedly vibrating the mining headlamps up and down, and then repeatedly extending and retracting the telescopic section of the hydraulic push rod 465, so that the hydraulic push rod 465 drives the positioning plate 461 to move back and forth up and down, and the positioning plate 461 drives the pushing cam 464 to move back and forth up and down by rotating the motor 462, thereby simulating the irregular up and down shaking of the mining headlamps by miners when walking by means of the pushing cam 464 that rotates and moves back and forth up and down.

[0059] After the mining headlamp has been inspected for a certain period of time, the rotation of the rotating motor 462, the execution motor 4452, the driving motor 455 and the reciprocating movement of the telescopic section of the hydraulic push rod 465 are stopped, and then the operator removes the mining headlamp from the mounting plate 42, and then powers on the mining headlamp. Subsequently, by observing whether the lighting brightness of the mining headlamp is within a fixed range, it is determined whether the connection of the circuit board and wires inside the mining headlamp is stable under vibration, and then whether the durability of the mining headlamp is qualified is determined.

[0060] When testing the durability of the mining headlamp, the present invention also includes the following steps: In the first step, the operator fixes the connecting socket of the mining headlamp on the front side of the mounting plate 42, and then the operator rotates the lamp head of the mining headlamp so that there is a certain angle between the lamp head and the connecting socket, and then the operator moves the laser rangefinder 432 to face the top of the lamp head of the mining headlamp, so that the laser rangefinder 432 can detect the position of the lamp head of the mining headlamp in real time.

[0061] The second step is to start the execution motor 4452, which drives the two toggle rods 4456 to rotate in opposite directions in an alternating manner, so that the toggle rods 4456 drive the movable plate 442 to move back and forth left and right. The movable plate 442 drives the mining headlamp to rotate back and forth left and right through the mounting plate 42, and the blocking plate 446 can stop the mining headlamp from rotating instantly, thereby simulating the situation where the miner turns his head left and right.

[0062] The third step, when it is necessary to shake the mining headlamp up and down at a uniform speed, the operator fixes the L-shaped plate 453 and the active rack 452 together through the pin, and manually rotates the rotating screw 4572 to push the locking plate 457 to move backward, and then starts the driving motor 455 to drive the mining headlamp to shake up and down at a uniform speed through the active rack 452. When it is necessary to perform a rapid shaking test on the mining headlamp, the operator pulls out the pin on the L-shaped plate 453, manually rotates the rotating screw 4572 to push the locking plate 457 to move forward, and then the operator manually pushes the locking plate 457 forward and starts the driving motor 455, so that the L-shaped plate 453 compresses the spring telescopic rod, and then the triangular plate 459 pushes the locking plate 457 backward, so that the spring telescopic rod instantly pushes the active rack 452 downward, thereby causing the mining headlamp to shake upward quickly and stop instantly, and then the driving motor 455 drives the mining headlamp to shake downward through the active rack 452.

[0063] The fourth step is to start the rotating motor 462 and repeatedly extend and retract the telescopic section of the hydraulic push rod 465, so that the pushing cam 464, which rotates and moves up and down, cooperates with the return spring to push the mining headlamp to vibrate irregularly up and down, thereby simulating the irregular up and down shaking of the mining headlamp by the miners when walking.

[0064] The fifth step, when the change in the distance measurement value read from the laser rangefinder 432 exceeds the specified range, it is judged that the connection stability between the lamp holder and the connecting socket of the mining headlamp in actual use is unqualified, thereby concluding that the durability of the mining headlamp is unqualified. After testing the mining headlamp for a certain period of time, the operator removes the mining headlamp from the mounting plate 42, and then powers on the mining headlamp. When it is observed that the lighting brightness of the mining headlamp is not within the fixed range, it is judged that the durability of the mining headlamp is unqualified.

[0065] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
