DETAILED DESCRIPTION
[0023] The following is combined with Figure 1 -Attached Figure 5 The utility model is further described in detail:
[0024] The utility model discloses an integrated bow-net detection device, such as Figure 1 , Figure 2 , Figure 3As shown, an integrated bow-net detection device of the utility model includes a protective shell 1 and a bow-net detection device body 2. The protective shell 1 is fixedly installed on the top of the train by bolts. A glass corresponding to the bow-net detection device body 2 is fixedly installed on one side of the protective shell 1. A sliding seat 3 is slidably connected inside the protective shell 1. An elastic fixing mechanism for fixing the bow-net detection device body 2 is provided on the top of the sliding seat 3. The bow-net detection device body 2 is fixedly connected to the top of the sliding seat 3 by the elastic fixing mechanism. In this embodiment, by providing the sliding seat 3, the bow-net detection device body 2 can be adjusted according to the contact position between the pantograph and the contact network, thereby improving the detection accuracy. By providing the elastic fixing mechanism, the bow-net detection device body 2 can be easily disassembled, which can be disassembled for maintenance, and the train can continue to run by replacing a new bow-net detection device body 2 during busy hours.
[0025] like Figure 2 , Figure 3 As shown, a servo motor 11 is fixedly installed on the inner wall of the protective shell 1 by bolts, and two sliding columns 12 are arranged inside the protective shell 1. The surfaces of the two sliding columns 12 are slidably connected with a sliding seat 3. A threaded hole penetrating the sliding seat 3 is opened on the side wall of the sliding seat 3, and a screw rod 13 is threadedly connected in the threaded hole. One end of the screw rod 13 is rotatably connected to the inner wall of the protective shell 1 through a bearing, and the other end of the screw rod 13 is fixedly connected to the output end of the servo motor 11 through a coupling; in this embodiment, the servo motor 11 is fixedly installed on the top of the bottom wall of the protective shell 1, and the two sliding columns 12 are fixed between the two opposite inner walls of the protective shell 1. The screw rod 13 is rotated by the servo motor 11, and the sliding seat 3 threadedly connected to the screw rod 13 will move in the horizontal direction along the sliding column 12.
[0026] like Figure 2 , Figure 4 , Figure 5 As shown, the elastic fixing mechanism includes a limit pin 41, a spring 42 and a pressure plate 43; the side wall of the bow-net detection device body 2 extends outward to form a fixing portion 21, and two symmetrical fixing plates 31 are arranged on the top of the sliding seat 3. The fixing plate 31 is L-shaped, and a through hole is opened on the top of the fixing plate 31. The limit pin 41 is arranged in the through hole, and the side wall of the limit pin 41 is integrally formed with a pressure plate 43 for pressing the fixing portion 21. One end of the spring 42 is welded to the top of the pressure plate 43, and the other end of the spring 42 is welded to the fixing plate 31; in this embodiment, the specific shape of the fixing plate 31 is as shown in FIG. Figure 2 , Figure 3As shown; the fixed plate 31 is L-shaped, and the fixed plate 31 is symmetrically arranged at both ends of the sliding seat 3, so that the bow-net detection device body 2 can slide between the two fixed plates 31 through the fixed part 21. The advantage of this is that when the bow-net detection device body 2 moves with the sliding seat 3, the two fixed plates 31 can play a limiting role. When in use, lift the limit pin 41 and the spring 42 will be compressed, and the bow-net detection device body 2 is pushed between the two fixed plates 31. Release the limit pin 41, and the spring 42 will push the pressure plate 43 to tightly cover the top surface of the fixed part 21, which plays a limiting function for the bow-net detection device body 2. Preferably, the number of limit pins 41 is N, N ≥ 2. In this embodiment, the number of limit pins 41 is 4, and they are arranged on the two fixed plates 31 opposite to each other.
[0027] like Figure 4 , Figure 5 As shown, a first fixing hole 22 penetrating the fixing part 21 is provided at the top of the fixing part 21, a second fixing hole 32 is provided at the top of the sliding seat 3 at a position corresponding to the first fixing hole 22, and a stop pin 41 passes through the first fixing hole 22 and is inserted into the second fixing hole 32; in this embodiment, the specific structure of the stop pin 41 and the pressure plate 43 is as shown in FIG. Figure 5 As shown, a pressure plate 43 is formed on the side wall of the limit pin 41, and the pressure plate 43 is pressed on the top of the fixing part 21. One end of the limit pin 41 passes through the fixing plate 31 and extends outside the fixing plate 31, and the other end of the limit pin 41 enters the second fixing hole 32. It is worth noting that when the limit pin 41 passes through the fixing plate 31 and enters the second fixing hole 32, the limit pin 41 will cooperate with the fixing plate 31, so that the limit pin 41 will be firmly fixed in a vertical state and will not be displaced. When in use, when the bow-net detection device body 2 reaches the specified position, the limit pin 41 will pass through the first fixing hole 22 and enter the second fixing hole 32 under the action of the spring 42. At this time, the pressure plate 43 will also be tightly pressed on the top surface of the fixing part 21. Through the cooperation of the positioning pin and the pressure plate 43, the bow-net detection device body 2 is fixed on the top of the sliding seat 3.
[0028] like Figure 1 , Figure 4 As shown, an inspection door 14 is hinged on the side wall of the protective shell 1, and a handle 23 for pulling the bow-net detection equipment body 2 is provided on the side wall of the bow-net detection equipment body 2; in this embodiment, by providing the inspection door 14 and the handle 23, when disassembling, the inspection door 14 is opened, and the limit pin 41 is pulled upwards, and the bow-net detection equipment body 2 can be pulled out from the top of the sliding seat 3 through the handle 23.
[0029] The implementation principle of the embodiment of the utility model is:
[0030] When it is necessary to adjust the position of the pantograph in contact with the contact network, start the servo motor 11 to rotate the screw rod 13, and the sliding seat 3 threadedly connected to the screw rod 13 will move in the horizontal direction along the sliding column 12 to adjust the pantograph-net detection device body 2 to a suitable position;
[0031] When disassembly is required, open the inspection door 14 , lift the limit pin 41 upwards, and pull the bow-net detection device body 2 out from the top of the sliding seat 3 through the handle 23 .
[0032] When installation is required, lift the limit pin 41 upwards, then the spring 42 will be compressed, pushing the bow-net detection device body 2 between the two fixed plates 31. When the bow-net detection device body 2 reaches the specified position, the limit pin 41 will pass through the first fixed hole 22 and enter the second fixed hole 32 under the action of the spring 42. At this time, the pressure plate 43 will also be tightly pressed on the top surface of the fixed part 21.
[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field.
