DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-7 The utility model provides a portable automatic over-phase detection device, including a first shell 1 and a second shell 2, the first shell 1 and the second shell 2 are hinged, a fixing mechanism 3 is arranged in the first shell 1, a measuring mechanism 4 is arranged in the second shell 2, a first slide groove 5 is opened in the second shell 2, a first connecting block 6 is slidably connected in the first slide groove 5, a second connecting block 7 is arranged on the measuring mechanism 4, and the second connecting block 7 is rotatably connected with the first connecting block 6, a limit block 8 is installed on the second shell 2, a limit groove 801 is opened on the limit block 8, a fixing block 9 is arranged on the measuring mechanism 4, and the cross section of the fixing block 9 is T-shaped.
[0023] The detection device can be folded by hingedly connecting the first shell 1 and the second shell 2, thereby reducing the overall length of the detection device. The foldable first shell 1 and the second shell 2 reduce the occupied space, making the detection device easier to store or carry when not in use.
[0024] The measuring mechanism 4 is arranged in the second housing 2, which can further reduce the length of the detection device. When the measuring mechanism 4 is needed, the measuring mechanism 4 is pulled toward one end to drive the first connecting block 6 to slide in the first slide groove 5. When the first connecting block 6 slides to the other end of the first slide groove 5, the measuring mechanism 4 can move out of the inner cavity of the second housing 2. At the same time, the measuring mechanism 4 is flipped, and the second connecting block 7 can be flipped 90 degrees relative to the first connecting block 6, so that the measuring mechanism 4 is perpendicular to the second housing 2. At the same time, the fixing block 9 is inserted into the inner cavity of the limiting groove 801 to fix the measuring mechanism 4 to avoid shaking during use.
[0025] Furthermore, the first housing 1 can be conveniently mounted on the rails through the fixing mechanism 3, thereby fixing the detection device.
[0026] As an optional embodiment, the fixing mechanism 3 includes a screw 301, a threaded block 302, a clamp 303 and a through hole 304; the through hole 304 is opened on the first shell 1, one end of the screw 301 is rotatably connected to the first shell 1, and the other end of the screw 301 extends out of the first shell 1, the threads at both ends of the outer wall of the screw 301 are in opposite directions, the number of the threaded blocks 302 is two, and the threaded blocks 302 are threadedly connected to the screw 301, the clamp 303 is arranged at the bottom end of the threaded block 302, and the end of the clamp 303 away from the threaded block 302 extends out of the through hole 304.
[0027] During the specific operation, two clamping plates 303 are placed on both sides of the rail. The screw rod 301 is rotated to drive the two threaded blocks 302 to move inward at the same time, so that the clamping plates 303 and the rail are closely fitted, so that the first housing 2 can be fixed on the top of the rail. And 304 can effectively prevent the threaded block 302 from rotating with the screw rod 301, ensuring that the threaded block 302 can move on the screw rod 301.
[0028] As an optional embodiment, a rotating disk 305 is installed at one end of the screw rod 301 extending out of the first housing 1. The rotating disk 305 can be provided to facilitate the staff to rotate the screw rod 301.
[0029] As an optional embodiment, the measuring mechanism 4 includes a measuring column 401, a scale line 402, a first groove 403, a second slide groove 404, a slider 405, a pressure rod 406 and a spring 407; the measuring column 401 is arranged in the second shell 2, the scale line 402 is arranged on the measuring column 401, the number of the first groove 403 is two, the first groove 403 is opened on the measuring column 401, the second slide groove 404 is opened in the first groove 403, the slider 405 is slidably connected to the second slide groove 404, the pressure rod 406 is connected to the slider 405 through a positioning bearing, the spring 407 is arranged in the first groove 403, and the spring 407 provides elastic force for the pressure rod 406, a cross bar 10 is rotatably installed on the second shell 2, the cross bar 10 is opened with a second groove 1001, a fixed column 11 is arranged on the second shell 2, and the second groove 1001 is mounted on the fixed column 11.
[0030] In this embodiment, the installation height requirement of the bottom center position of the automatic over-phase sensor and the rail surface is 110+10mm, the spacing requirement of the bottom center position of the automatic over-phase sensor and the inner side of the rail is 300±10mm, the standard size of the automatic over-phase sensor is cylindrical, with a diameter of 100.0mm and a height of 70.0mm. The basic rail type is the main type 60 rail, the width of the head top surface is 73.0mm, the height is 176.0mm, and the rail waist chamfer is R25. Based on the above specifications, the scale range of the scale line 402 is set to 10-140mm to cover the required measurement range. Since the rail is fixed on the ground, the automatic over-phase device is fixed under the motor vehicle, adjacent to the rail, so it is necessary to use a square ruler for measurement.
[0031] When measurement is required, after the measuring mechanism 4 is moved out of the inner cavity of the second housing 2 according to the above principle, the pressure rod 406 is turned 90 degrees by the handle 12. Figure 2 The diagram is shown as the expanded schematic diagram. Press the pressure rod 406 down so that the pressure rod 406 close to the automatic over-phase sensor is close to the center point of the bottom of the automatic over-phase sensor. At the same time, release the pressure rod 406, and the spring 407 pops out, which can push the pressure rod 406 to contact the center bottom surface of the over-phase sensor, so that the pressure rod 406 floats on the scale line 402 to obtain the value. Compare the obtained value with the specified range of the distance between the rail surface and the center point of the bottom surface of the automatic over-phase sensor. If the measured value is within the specified range, the measurement is passed, otherwise the position of the automatic over-phase sensor is recorded and adjusted.
[0032] Furthermore, the pressure rod 406 is connected to the slider 405 via a positioning bearing. The positioning bearing is a prior art, which can fix the pressure rod 406 after rotation to avoid further rotation, thereby ensuring more accurate detection.
[0033] When the second groove 1001 is mounted on the fixing column 11 , the measuring mechanism 4 can be located in the inner cavity of the second shell 2 , and the measuring mechanism 4 can be fixed to prevent it from sliding out of the inner cavity of the second shell 2 .
[0034] As an optional embodiment, a handle 12 is provided on the pressure rod 406. The provision of the handle 12 allows the staff to turn the pressure rod 406 more conveniently.
[0035] As an optional embodiment, magnets 13 are respectively installed on the first shell 1 and the second shell 2. When the second shell 2 is flipped to be on the same straight line as the first shell 1, the magnets 13 on the first shell 1 and the second shell 2 contact and attract each other.
[0036] The magnet 13 can be used to make the first shell 1 and the second shell 2 stick together at adjacent ends to attract and fix each other, thereby preventing the first shell 1 and the second shell 2 from separating during the detection process.
[0037] Therefore, through the above technical solution, the portable automatic phase-over detection device can be folded, which greatly reduces the space occupied and is easy to carry. The detection mechanism 4 can be retracted into the second shell 2, further reducing the space occupied by the detection device. At the same time, the detection mechanism 4 can be protected by the second shell 2.
