[0021] To address the aforementioned issues, this embodiment provides an electrical safety testing device for open-pit mines. Figure 1 This is a three-dimensional structural diagram of an electrical safety testing device for open-pit mines provided in this embodiment. Figure 2 This is a partial cross-sectional view of an electrical safety testing device for open-pit mines provided in this embodiment. Figure 3 This is a schematic diagram of the internal structure of an electrical safety testing device for open-pit mines provided in this embodiment.

[0022] like Figures 1-3 As shown, the open-pit mine electrical safety testing equipment of this embodiment includes a base plate 1, a gantry 2, an adjusting seat 3, a push rod 4, and a protective cover 5. The bottom of the base plate 1 is equipped with a caster wheel structure 6. The gantry 2 is telescopic. The bottom of the gantry 2 is hinged to the base plate 1. The top of the gantry 2 is equipped with a limiting protrusion 25. When the gantry 2 is laid down, it fits against the base plate 1. When the gantry 2 is erected, it is perpendicular to the base plate 1. The adjusting seat 3 is rotatably mounted on the top of the gantry 2. The adjusting seat 2 is equipped with an opening 34. The limiting protrusion 25 can be inserted into the opening 34 to fix the adjusting seat 3. The adjusting seat 3 is equipped with a slot 35 and a testing component 7. The testing component 7 is used to test electrical equipment. One end of the push rod 4 is hinged to the base plate 1, and the other end of the push rod 4 is equipped with a plug-in structure 8. When the gantry 2 is erected and the limiting protrusion 25 is inserted into the opening 34, the plug-in structure 8 can be inserted into the slot 35. Push rod 4 can push adjustment seat 3 to raise the detection component to be closer to the electrical equipment. Protective cover 5 is closable and mounted on base plate 1. When protective cover 5 is open, gantry 2 can be erected. When gantry 2 is lowered, protective cover 5 can be closed, and gantry 2, adjustment seat 3 and push rod 4 are secured inside.

[0023] In this embodiment, as Figure 2 and Figure 3 As shown, a pair of support blocks 14 are provided on the base plate 1, and the two ends of the gantry 2 are respectively hinged to one support block 14. A stop block 15 is provided on the support block 14, allowing the gantry 2 to rest against the stop block 15 when it is erected. It can be understood that the gantry 2 can be hinged to the support block 14 by a torsion spring, and the torque provided by the torsion spring allows the gantry 2 to stand upright and abut against the stop block 15. Alternatively, a support rod can be provided on the side of the gantry 2 away from the stop block 15, and the gantry 2 will be abutted against the stop block 15 under the support of the support rod.

[0024] In this embodiment, as Figure 2 and Figure 3As shown, the base plate 1 has a groove 16, and the push rod 4 is hinged to the bottom of the groove 16. When the push rod 4 is in the folded-down state, the groove 16 can accommodate the push rod 4.

[0025] In this embodiment, the electrical safety testing equipment for open-pit mines is used by opening the protective cover 5, then raising the gantry 2 to be perpendicular to the base plate 1, and then rotating the adjusting seat 3 so that the side of the adjusting seat 3 with the slot 35 faces the base plate 1, and the side of the adjusting seat 3 with the detection component 7 faces the side of the gantry 2. At this time, the limiting protrusion 25 on the gantry 2 can be inserted into the opening 34 on the adjusting seat 3 to fix the relative position of the adjusting seat 3 and the gantry 2. Then, the push rod 4 is raised and extended until the insertion structure 8 is inserted into the slot 35 so that the push rod 4 is connected to the adjusting seat 3. Then, the push rod 4 is extended further to push the adjusting seat 3, which in turn causes the gantry 2 to extend, raising the adjusting seat 3 to the detection height. Then, the detection component 7 is used to test the electrical equipment. It is convenient to use, has a wide range of applications, and has a stable structure, making it easy to place in any location. After use, retract the push rod 4 to restore the gantry 2 to its initial height. Then, continue retracting the push rod 4 to pull the plug-in structure 8 out of the slot 35. Next, lay down the push rod 4 and the gantry 2 so that the gantry 2 and the push rod 4 are attached to the base plate 1. At this time, the adjusting seat 3 is also placed on the base plate 1 along with the gantry 2. Press down the limiting protrusion 25 to disengage the limiting protrusion 25 from the hole 34. Then, rotate the adjusting seat 3 so that the side of the adjusting seat 3 with the slot 35 is attached to the base plate 1 to avoid interference between the detection component 7 and the base plate 1. Finally, close the protective cover 5 to secure the gantry 2, the adjusting seat 3, and the push rod 4 inside. This not only provides dust protection for the gantry 2, the adjusting seat 3, and the push rod 4, but also reduces the space occupied by the detection equipment, making it easier to store and transport.

[0026] Figure 4 This is a top view of a gantry 2 provided in this embodiment. In some embodiments, such as... Figure 4 As shown, the gantry 2 includes a horizontal bar 24 and a pair of vertical bars. Each vertical bar includes an outer cylinder 21, an inner bar 22, and a tension spring 23. The outer cylinder 21 has a closed end and an open end. The closed end of the outer cylinder 21 is hinged to the base plate 1. The inner bar 22 is telescopically inserted into the open end of the outer cylinder 21. The tension spring 23 is disposed within the outer cylinder 21 and connects the closed end of the outer cylinder 21 to the inner bar 22. Both ends of the horizontal bar 24 are respectively connected to one of the inner bars 22.

[0027] In this embodiment, as Figure 3 As shown, the closed end of the outer cylinder 21 is hinged to the base 1. Furthermore, the closed end of the outer cylinder 21 is hinged to the support block 14.

[0028] In this embodiment, as Figure 4 As shown, the limiting protrusion 25 is telescopically mounted on the crossbar 24.

[0029] In this embodiment, as Figure 4 As shown, the inner rod 22 is L-shaped, and the crossbar 24 is inserted between the two inner rods 22. This arrangement facilitates the installation of the crossbar 24.

[0030] The gantry 1 in this embodiment includes a horizontal bar 24 and a pair of vertical bars. Each vertical bar includes an outer cylinder 21, an inner rod 22, and a tension spring 23. Under the action of the tension spring 23, the vertical bar can extend and retract to adjust its length. Under the pushing force of the push rod 4, the tension spring 23 is stretched, and the vertical bar lengthens. When the pushing force is removed, the tension spring 23 contracts, and the vertical bar shortens.

[0031] In some embodiments, see Figure 4 The limiting protrusion 25 includes a compression spring and a protrusion portion. A mounting groove is provided on the crossbar 24. The protrusion portion is vertically and retractably disposed within the mounting groove. The compression spring is disposed within the mounting groove and is connected between the bottom of the mounting groove and the protrusion portion.

[0032] In this embodiment, the limiting protrusion 25 includes a compression spring and a protrusion. When the protrusion is pressed down, the compression spring is compressed, the protrusion exits the opening 34 and retracts into the mounting groove, thus releasing the locking of the adjusting seat 3.

[0033] Figure 5 This is a side view of an adjustment seat 3 provided in this embodiment. In some embodiments, such as... Figure 5 As shown, the adjusting seat 3 includes a sleeve 31 and a mounting plate. The sleeve 31 is rotatably fitted onto the gantry 2. An opening 34 is located on the sleeve 31. The mounting plate is L-shaped and includes a first plate surface 32 and a second plate surface 33 that are connected to each other. The sleeve 31 is connected to the mounting plate and is located in the area between the first plate surface 32 and the second plate surface 33. A slot 35 is provided on the side of the first plate surface 32 away from the sleeve 31. A detection component 7 is provided on the side of the second plate surface 33 away from the sleeve 31.

[0034] In this embodiment, as Figure 5 As shown, sleeve 31 is connected to the second plate surface 33.

[0035] The adjusting seat 3 in this embodiment includes a sleeve 31 and a mounting plate. The sleeve 31 is rotatably fitted onto the crossbar 24. When the gantry 2 is in an upright state, rotating the adjusting seat 3 so that the first plate surface 32 faces the base plate 1, at which point the limiting protrusion 25 on the crossbar 24 can be inserted into the opening 34 to position the adjusting seat 3. When it is necessary to release the positioning of the adjusting seat 3, simply press the limiting protrusion 25 down into the opening 34 to retract the limiting protrusion 25 into the crossbar 24 until it disengages from the opening 34, and then the adjusting seat 3 can be rotated. Therefore, when the gantry 2 is rotated 90 degrees from an upright state to a folded state, the adjusting seat 3 can also be rotated 90 degrees to ensure that the first plate surface 32 can fit against the base plate 1 for easy storage. In some embodiments, two limiting protrusions 25 can be provided in the circumferential direction of the crossbar 24, with the two limiting protrusions 25 spaced 90 degrees apart. The two limiting protrusions 25 position the adjusting seat 3 during use and storage of the equipment, respectively.

[0036] In some embodiments, such as Figure 5 As shown, the detection assembly 7 includes a connecting base 71, an electric push rod 72, and a temperature sensor 73. The connecting base 71 is hinged to the adjusting base 3. One end of the electric push rod 72 is connected to the connecting base 71. The temperature sensor 73 is located at the end of the electric push rod 72 away from the connecting base 71.

[0037] The detection component 7 in this embodiment includes a connector 71, an electric push rod 72, and a temperature sensor 73. In the stowed state, as... Figure 5 As shown, the connecting seat 71, the electric push rod 72, and the temperature sensor 73 are attached to the second plate surface 33. In use, the connecting seat 71 can be rotated 90 degrees around the hinge point so that the detection component 7 is perpendicular to the second plate surface 33, and the temperature sensor 73 extends away from the second plate surface 33 to facilitate the detection of the temperature at the location of the electrical equipment.

[0038] Figure 6 A side view of a push rod 4 provided for this embodiment. In some embodiments, such as Figure 6 As shown, the push rod 4 includes a hinge seat 41, a threaded rod 42, a threaded cylinder 43, a connector 44, and a connecting rod 45. The hinge seat 41 is hinged to the base plate 1. The threaded rod 42 is connected to the hinge seat 41. The threaded cylinder 43 is sleeved on the end of the threaded rod 42 away from the hinge seat 41. The connector 44 is disposed on the end of the threaded cylinder 43 away from the hinge seat 41. The connecting rod 45 is rotatably mounted on the connector 44. A plug-in structure 8 is disposed on the end of the connecting rod 45 away from the connector 44. By rotating the threaded cylinder 43, the connecting rod 44 can be pushed to move away from the threaded rod 42.

[0039] In this embodiment, the push rod 4 uses the cooperation between the threaded rod 42 and the threaded cylinder 43 to adjust the overall length in order to provide thrust to the adjusting seat 3. The structure is stable and reliable, and the length adjustment is flexible and reliable.

[0040] In some embodiments, such as Figure 6 As shown, a pair of through holes 46 are symmetrically arranged at the end of the push rod 4. The through holes 46 are L-shaped, with one end connected to the end face of the push rod 4 and the other end connected to the side of the push rod 4. The insertion structure 8 includes a pair of claws 81, a pair of pressing blocks 82, and a pair of return springs 83. Each claw 81 is inserted into a through hole 46 from the end face of the push rod 4. The claw 81 can move radially along the push rod 4 within the through hole 46. Each pressing block 82 is inserted into a through hole 46 from the side of the push rod 4 and connected to the claw 81 in the through hole 46. Each return spring 83 is disposed in a through hole 46 and provides a thrust for the claw 81 to move radially outward from the push rod 4. When the pressing block 82 is pressed, the return spring 83 can be contracted, thereby causing the claw 81 to move radially inward from the push rod 4, so as to insert the pair of claws 81 into the slot 35.

[0041] In this embodiment, as Figure 6 As shown, the claw 81 and the pressing block 82 are connected to each other to form an integrated structure.

[0042] In this embodiment, the end of the claw 81 has a hook-shaped structure that conforms to the shape of the slot 35. The locking between the end of the claw 81 and the slot 35 can be released quickly and easily by pressing down on the pressing block 82.

[0043] In some embodiments, such as Figure 2 and 3 As shown, the base plate 1 has sliding grooves 11 on opposite sides. Each sliding groove 11 has a sliding rod 12. A slider 13 is provided on the sliding rod 12. The protective cover 5 is fastened to the base plate 1, and the opposite sides of the protective cover 5 are respectively connected to a slider 13. The protective cover 5 can slide along the sliding rod 12 to cover or expose the gantry 2, the adjusting seat 3 and the push rod 4.

[0044] In this embodiment, the protective cover 5 slides onto the base plate 1 for easy opening and closing. However, it should be noted that to prevent interference between the protective cover 5 and the gantry 2 or other structures on the base plate 1 during sliding, one end of the protective cover 5's sidewall in the sliding direction is open. For example... Figure 2 In the middle, the left side wall of the protective cover 5 is open, allowing the protective cover 5 to slide open to the right.

[0045] In some embodiments, such as Figure 3 As shown, the gantry 2 also includes a lighting lamp 9. The lighting lamp 9 is located near the adjustment seat 3. The lighting lamp 9 installed on the gantry 2 can provide illumination for electrical equipment in dark environments, making it easier to observe.

[0046] In some embodiments, such as Figure 1As shown, the caster wheel structure 6 includes multiple rotating wheel frames 61 and multiple rollers 62. The rotating wheel frames 61 are disposed on the bottom surface of the base plate 1. Each roller 62 is rotatably mounted on one rotating wheel frame 61.

[0047] In this embodiment, a caster wheel structure 6 is provided on the bottom surface of the base plate 1 to facilitate the movement of the testing equipment.

[0048] Additionally, it should be noted that the detection device in this embodiment can be powered by an external power source or by a battery.

[0049] Before using the electrical safety testing equipment for open-pit mines implemented in this invention, the equipment is moved to the target location using the caster wheel structure 6; then the equipment is connected to the power supply to ensure that the equipment can be used normally.

[0050] When in use, slide the protective cover 5 to the right, and the slider 13 slides to the right along the slide bar 12 inside the slide groove 11, exposing the gantry 2, the adjusting seat 3 and the push rod 3.

[0051] Then rotate the gantry 2 ninety degrees to stand it up, and then rotate the adjusting block 3 ninety degrees so that the opening 34 is engaged and fixed with the limiting protrusion 25, and the slot 35 faces the base plate 1.

[0052] Next, rotate push rod 4 upwards by 90 degrees so that the position of insertion structure 8 corresponds to that of slot 35.

[0053] Then rotate the threaded cylinder 43 to push the connecting rod 45 towards the adjusting seat 3 until the insertion structure 8 abuts against the entrance of the slot 35.

[0054] Then press down on the pressing block 82, causing the return spring 83 to contract and a pair of claws 81 to move closer to each other so that the hook-shaped structure at the end of the claws 81 can extend into the slot 35; then release the pressing block 82, and at the same time the return spring 83 rebounds and pushes the claws 81 to lock into the inside of the slot 35 for fixation.

[0055] Then continue to rotate the threaded cylinder 43 and move it along the threaded rod 42 to push the connecting rod 45 to move the adjusting seat 3 away from the base plate 1. At this time, the inner rod 22 of the gantry 2 slides inside the outer cylinder 21, and the tension spring 23 is stretched.

[0056] When the detection component 7 reaches the detection position, stop rotating the threaded cylinder 43, rotate the connecting seat 71, and rotate the temperature sensor 73 away from the second plate surface 33 until the electric push rod 72 is perpendicular to the second plate surface 33. Then, the electric push rod 72 can be driven to extend and bring the temperature sensor 73 closer to the electrical equipment.

[0057] Similarly, during storage, rotate the threaded cylinder 43 in the opposite direction to reset it, shortening the gantry 2. Then press down the pressing block 82 to disengage the claw 81 from the slot 35. Next, press the limiting protrusion 25 to loosen the locking mechanism of the opening hole 34, allowing the adjusting seat 3 to rotate 90 degrees on the crossbar 24. Lay the gantry 2 and push rod 4 on the base plate 1, ensuring the first plate surface 32 of the adjusting seat 3 is flush with the base plate 2. Then push the protective cover 5 back to cover the gantry 2, adjusting seat 3, and push rod 4, providing protection and preventing accidental damage during transportation and storage. This also reduces the overall footprint of the device, facilitating storage and portability, thus enabling convenient detection, prevention, and control of safety accidents in open-pit mine industrial production.
