A reciprocating sleeve 31 is fitted onto the outer side of the reciprocating screw 15. The reciprocating sleeve 31 is fixedly connected to the moving frame 6. A rotating cylinder 29 is rotatably connected to the moving frame 6. Multiple fixing rods 34 are fixedly connected to the inner circumference of the rotating cylinder 29. The rotating shaft 16 has multiple slots that match the fixing rods 34. The fixing rods 34 are inserted into the slots and slidably connected to the slots, so that the rotating shaft 16 and the rotating cylinder 29 are slidably sleeved. A seventh gear 35 is fixedly connected to the outer side of the rotating cylinder 29. A through slot 30 is opened on the upper side of the moving frame 6. A moving box 32 is slidably connected inside the moving frame 6. A seventh rack 36 is fixedly connected to the side wall of the moving box 32. The seventh rack 36 and the seventh gear 35 mesh with each other. A hot air gun 37 is fixedly installed inside the moving frame 6. A fixing pipe is fixedly connected to the side wall of the moving box 32. The fixing pipe is connected to the output end of the hot air gun 37 through a hose. A notch is opened on the side wall of the moving box 32. A control assembly is mounted on the mounting frame 5. The control assembly includes a motor 14 fixedly mounted inside the mounting frame 5, a reciprocating screw 15 fixedly connected to the output end of the motor 14, a first control shaft 21 rotatably connected inside the mounting frame 5, and third gears 20 fixedly connected to the outer sides of both the first control shaft 21 and the reciprocating screw 15, with the two third gears 20 meshing. A control cam 22 is fixedly connected to the outer side of the first control shaft 21. A slide plate 23 is slidably mounted inside the mounting frame 5, and a control groove is opened on the outer side of the control cam 22.

A sixth gear 28 is fixedly connected to the outer side of the rotating shaft 16, with the sixth gear 28 meshing with the fifth gear 27. Before testing, insert the mounting rod 11 between the second arc plate 13 and the fixed frame 10. Adjust the positions of the mounting frame 5 and the moving frame 6 according to the actual working condition of the cable to be measured, so that the moving range of the moving frame 6 is located in the position where the cable is prone to damage. Rotate the second threaded rod 12, which drives the second arc plate 13 to move until the second arc plate 13, the mounting rod 11, and the fixed frame 10 are tightly abutted together, thereby completing the adjustment and fixing operation of the overall position of the mounting frame 5. Secondly, the hot air gun 37 is a common instrument that heats air by electric heating wire and sprays controllable hot air flow. In the scheme, when the detection is carried out, the hot air gun 37 can be started, and the temperature rise phenomenon when an explosion suddenly occurs near the cable in actual work can be simulated. Then, during the detection process, the motor 14 can be started, and the reciprocating screw rod 15 is driven to rotate. The reciprocating screw rod 15, the reciprocating sleeve 31 and the reciprocating screw structure in real life have the same principle, and under the limiting action of the rotating shaft 16 and the rotating cylinder 29, the moving frame 6 and the mounting frame 5 are in upper and lower sliding connection. Therefore, the rotating reciprocating screw rod 15 drives the reciprocating sleeve 31 and the moving frame 6 to move upward or downward as a whole, During this process, Figure 5 It can be known that the control groove is composed of two parts, namely the circular part and the oval part. When the sliding plate 23 and the circular part are in sliding connection, the sliding plate 23 stops moving. However, when the sliding plate 23 and the oval part are in sliding connection, the sliding plate 23 moves left and right relative to the mounting frame 5. That is, during the rotation of the reciprocating screw rod 15, the first control shaft 21 and the control cam 22 are driven to rotate under the action of the third gear 20. Under the action of the control groove, the sliding plate 23 moves left and right intermittently. The intermittent here means that the sliding plate 23 first stops moving, then moves to the right, then moves to the left, and then stops moving. The sliding plate 23 reciprocates as a whole. The fourth rack 24 is driven to move left and right intermittently by the sliding plate 23. The fourth gear 26 is driven to rotate left and right intermittently by the fourth rack 24. The fourth gear 26 drives the fifth gear 27 to rotate left and right intermittently by the second control shaft 25. The fifth gear 27 drives the rotating shaft 16 to rotate left and right intermittently by the sixth gear 28. The rotating shaft 16 drives the rotating cylinder 29 and the seventh gear 35 to rotate left and right intermittently by the fixed rod 34. The seventh gear 35 drives the seventh rack 36 to move left and right intermittently. The seventh rack 36 drives the moving box 32 to move left and right intermittently, During this process, the cable being detected is always located in the gap. During the movement of the moving box 32, the cable is always in the gap, Figure 7From the perspective of the moving box 32, the moving box 32 and the moving frame 6 right side exist a certain gap, when the moving box 32 starts to move to the right, the gap between the moving box 32 and the moving frame 6 gradually reduces, the moving box 32 enters the right side of the moving frame 6, at this time the moving box 32, the moving frame 6 can be approximately regarded as a closed space (the opening and closing control structure and principle of the gap is described below), the hot air gun 37 is started, the temperature inside the moving box 32 is increased, in this process, the data on the display screen on the front side of the body 1 can be observed, if the display screen data fluctuates greatly, it means that the wiring of the mine explosion-proof and intrinsically safe control box has a large quality problem, and more detailed detection is needed, if not, it means that the wiring quality of the mine explosion-proof and intrinsically safe control box is good, and finally the detection operation of the mine explosion-proof and intrinsically safe control box is completed.

[0015] The moving box 32 side wall is provided with two sliding grooves 51, the sliding grooves 51 are communicated with the gap, the square rod 38 is slidably connected in the sliding groove 51, the second extrusion plate 54 is fixedly connected to one side of the square rod 38 in the sliding groove 51, the second spring 55 is fixedly connected between the second extrusion plate 54 and the sliding groove 51, the first extrusion plate 52 is slidably connected to the side wall of the second extrusion plate 54, the first spring 53 is fixedly connected between the first extrusion plate 52 and the second extrusion plate 54, The U-shaped rod 39 is slidably connected in the moving frame 6, the U-shaped rod 39 is opposite to the first extrusion plate 52, the button 50 is fixedly connected outside the moving box 32, the cavity 41 is formed in the moving frame 6, the telescopic rod 18 is rotatably connected through the cavity 41, the telescopic rod 18 is rotatably connected with the mounting frame 5, the telescopic rod 18 is fixedly connected with the rotating cam 40 in the cavity 41, the control frame 43 is slidably connected in the cavity 41, the two connecting rods 44 are fixedly connected to the side wall of the control frame 43, the U-shaped rod 39 is threadedly connected with the connecting rod 44, the first gear 17 is fixedly connected outside the telescopic rod 18, the second gear 19 is fixedly connected outside the reciprocating lead screw 15, and the first gear 17 and the second gear 19 are engaged; Firstly, the button 50 is electrically connected with the hot air gun 37 through the wire 3, when the moving box 32 is located at the initial position, the button 50 is located in the through groove 30, when the moving box 32 starts to move into the right side of the moving frame 6, the button 50 abuts against the moving frame 6, the button 50 is started, and then the hot air gun 37 is started, finally the effect of automatically starting the hot air gun 37 is achieved, Secondly, the connecting rod 44 is "L" type, that is, the connecting rod 44 is composed of two connecting rods rotatably connected together, as shown in Figure 8As shown, the connecting rod 44 is composed of a transverse connecting rod and a vertical connecting rod, and the transverse connecting rod and the vertical connecting rod are rotationally connected, wherein one end of the transverse connecting rod away from the vertical connecting rod is threaded through the side wall of the cavity 41 and the U-shaped rod 39, and the other end of the vertical connecting rod away from the transverse connecting rod is fixedly connected with the control frame 43. Before the detection operation is performed, the positions of the upper and lower U-shaped rods 39 can be adjusted by rotating the transverse connecting rod threaded with the U-shaped rod 39, so that the end portions of the upper and lower U-shaped rods 39 are not in the same plane. During the rotation of the reciprocating screw rod 15, the first gear 17 and the second gear 19 drive the telescopic rod 18 to rotate, and the telescopic rod 18 drives the rotating cam 40 to rotate. The rotating cam 40 abuts against the control frame 43, which causes the control frame 43 to move back and forth intermittently. The control frame 43 drives the U-shaped rod 39 to move back and forth intermittently through the connecting rod 44. During the movement of the moving box 32, when the moving box 32 enters the right side area of the moving frame 6, the first pressing plate 52 and the second pressing plate 54 move with the moving box 32. The first pressing plate 52 abuts against the cable to be detected, which not only fixes the cable but also forms a simple sealing effect on the notch to reduce heat loss, In this process, refer to Figure 8 When the control frame 43 moves to the left, the control frame 43 drives the U-shaped rod 39 to move to the left through the connecting rod 44. When the U-shaped rod 39 abuts against the first pressing plate 52, the first pressing plate 52 moves to the left relative to the moving frame 6, and finally the cable and the first pressing plate 52 are disconnected. The first pressing plate 52 does not form clamping and fixing of the cable. Since the end portions of the upper and lower U-shaped rods 39 are not in the same plane, one of the first pressing plates 52 does not abut against the cable, or neither of the first pressing plates 52 abuts against the cable. When neither of the first pressing plates 52 abuts against the cable, the cable returns to the initial length. However, since the moving frame 6 is in a moving state at this time, detection of different positions of the cable is formed. For example, when the moving frame 6 moves upward as a whole, the upper first pressing plate 52 does not abut against the cable, and the lower first pressing plate 52 abuts against the cable, that is, the lower first pressing plate 52 forms extrusion and fixing of the cable. However, the upper first pressing plate 52 does not form extrusion and fixing of the cable. Therefore, when the moving frame 6 moves upward as a whole, the number of cables inside the moving box 32 gradually increases, It can be understood that the lower end of the cable is fixed, and the upper end is not fixed. Therefore, when the moving frame 6 moves upward, the cables are stacked in the moving frame 6, so that the number of cables in the moving frame 6 increases. It should be emphasized that the cable end connected with the detection head 7 is in a relaxed state between the nodes when the cable end abuts against the first pressing plate 52; If the first extrusion plate 52 on the upper and lower sides is not in contact with the cable, when the moving frame 32 moves up and down, the cable area located in the moving frame 32 is in a changing state, but the actual length of the cable located in the moving frame 32 does not change, the detection of different areas of the cable can be completed, and the accuracy of the detection result is improved.

[0016] The telescopic rod 18 is fixedly connected with the rotating plate 42 in the cavity 41, the swing rod 48 is rotatably connected with the side wall of the cavity 41, the swing rod 48 is fixedly connected with the rotating disc 45 on one side in the cavity 41, the torsion spring 49 is fixedly connected between the rotating disc 45 and the side wall of the cavity 41, the eccentric rod 47 is fixedly connected with the side wall of the rotating disc 45, the swing rod 48 is fixedly connected with the swing plate 46 on one side in the through slot 30, the swing plate 46 is fixedly connected with a plurality of moving rods 33, In the rotating process of the telescopic rod 18, the telescopic rod 18 drives the rotating plate 42 to rotate, when the rotating plate 42 and the eccentric rod 47 abut, the eccentric rod 47 and the rotating disc 45 rotate, the torsion spring 49 deforms, the rotating disc 45 drives the swing rod 48, the swing plate 46 and the moving rod 33 to rotate, until the eccentric rod 47 and the rotating plate 42 are disconnected, and then the moving rod 33 and the swing plate 46 swing back and forth as a whole in the rotating process of the telescopic rod 18, in the detection process, the moving rod 33 abuts against the cable, the cable moves, the possibility that the cable moves under the action of external force in actual use can be simulated, and the simulation of the actual use of the cable can be further completed.

[0017] In the application, when the electrical detection of the wiring of the mine explosion-proof and intrinsic safety type control box is needed, the cable to be detected is inserted into the clamping frame 4, the end of the cable abuts against the detection head 7, the first threaded rod 8 is rotated until the two first arc-shaped plates 9 abut against the outer surface of the cable, the body 1 is started, the electrical detection operation is started, the measurement data is displayed on the display screen in real time, the measurement data is recorded and analyzed, and finally the detection operation of the wiring of the mine explosion-proof and intrinsic safety type control box is completed. Before detection, the mounting rod 11 is inserted between the second arc-shaped plate 13 and the fixed frame 10, the positions of the mounting frame 5 and the moving frame 6 are adjusted, the moving range of the moving frame 6 is located at a position where the cable is prone to damage, the second threaded rod 12 is rotated until the second arc-shaped plate 13, the mounting rod 11 and the fixed frame 10 abut against each other tightly. In the process of detection, the motor 14 is started, the motor 14 drives the reciprocating screw rod 15 to rotate, the reciprocating screw rod 15 drives the reciprocating sleeve 31 and the moving frame 6 to move upward or downward as a whole, when the slide plate 23 and the circular portion are slidably connected, the slide plate 23 stops, but when the slide plate 23 and the elliptical portion are slidably connected, the slide plate 23 moves left and right relative to the mounting frame 5, that is, in the process of rotating the reciprocating screw rod 15, the first control shaft 21 and the control cam 22 are driven to rotate under the action of the third gear 20, and the slide plate 23 is driven to move left and right intermittently under the action of the control groove, the slide plate 23 reciprocates as a whole, and the fourth rack 24, the fourth gear 26, the second control shaft 25, the fifth gear 27, the sixth gear 28, the rotating shaft 16, the fixed rod 34, the rotating cylinder 29 and the seventh gear 35 are driven to rotate intermittently, the seventh gear 35 drives the seventh rack 36 and the moving box 32 to move left and right intermittently, In this process, the cable being detected is always located in the gap, and in the process of moving the moving box 32, there is a certain gap between the moving box 32 and the right side of the moving frame 6 in the initial state, when the moving box 32 starts to move to the right, when the moving box 32 enters the part on the right side of the moving frame 6, the moving box 32 and the moving frame 6 can be approximately regarded as a closed space, the hot air gun 37 is started, and the temperature inside the moving box 32 is increased, in this process, the data on the display screen on the front side of the body 1 can be observed, if the data on the display screen fluctuates greatly, it indicates that there is a large quality problem in the wiring of the mine explosion-proof and intrinsically safe control box, and more detailed detection is still needed, if not, it indicates that the quality of the wiring of the mine explosion-proof and intrinsically safe control box is good, Before the detection operation, the ends of the upper and lower U-shaped rods 39 are not in the same plane, in the process of rotating the reciprocating screw rod 15, the telescopic rod 18 and the rotating cam 40 are driven to rotate under the action of the first gear 17 and the second gear 19, the rotating cam 40 abuts against the control frame 43, which causes the control frame 43, the connecting rod 44 and the U-shaped rod 39 to move left and right intermittently, in the process of moving the moving box 32, when the moving box 32 enters the area on the right side of the moving frame 6, the first pressing plate 52 and the second pressing plate 54 move with the moving box 32, the first pressing plate 52 abuts against the cable to be detected, which not only fixes the cable, but also forms a simple sealing effect on the gap, reducing heat loss, In this process, when the control frame 43 moves to the left, the control frame 43 drives the U-shaped rod 39 to move to the left through the connecting rod 44, and when the U-shaped rod 39 and the first pressing plate 52 abut, it will cause the first pressing plate 52 to move to the left relative to the moving frame 6, and finally break the connection between the cable and the first pressing plate 52, and the first pressing plate 52 will not form a clamping and fixing to the cable. Because the ends of the U-shaped rods 39 on the upper and lower sides are not in the same plane, one of the first pressing plates 52 will not abut the cable, or both of the first pressing plates 52 will not abut the cable. For example, when the moving frame 6 moves upward as a whole, when the upper first pressing plate 52 does not abut the cable and the lower first pressing plate 52 abuts the cable, the lower first pressing plate 52 will form a pressing to the cable and fix the cable, but the upper first pressing plate 52 will not form a pressing to the cable. Therefore, when the moving frame 6 moves upward as a whole, the number of cables inside the moving box 32 will gradually increase, It can be understood here that the lower end of the cable is fixed and the upper end is not fixed, so when the moving frame 6 moves upward, the cables will be stacked in the moving frame 6, causing the number of cables in the moving frame 6 to increase. It should be emphasized here that the cable end connected to the detection head 7 is in a relaxed state between the nodes when the first pressing plate 52 abuts the cable; If both of the first pressing plates 52 on the upper and lower sides do not abut the cable, when the moving frame 32 moves up and down, the cable area inside the moving frame 32 is in a changing state, but the actual length of the cable inside the moving box 32 does not change, which can complete the detection of different areas of the cable and further improve the accuracy of the detection results; In the process of rotating the telescopic rod 18, the telescopic rod 18 drives the rotating plate 42 to rotate, and when the rotating plate 42 and the eccentric rod 47 abut, it will cause the eccentric rod 47 and the rotating disc 45 to rotate, and the torsion spring 49 will be deformed. The rotating disc 45 drives the swing rod 48, the swing plate 46, and the moving rod 33 to rotate until the eccentric rod 47 and the rotating plate 42 are disconnected, and further cause the moving rod 33 and the swing plate 46 to swing back and forth as a whole during the rotation of the telescopic rod 18.
