Description

Technical Field

[0001] The utility model relates to the technical field of speed reduction top detection, in particular to a state detection device for a speed reduction top. Background Art

[0002] The retarder is a hydraulic device installed on the rails. After the vehicle rolls over, the sliding cylinder cap acts as a brake to slow down the vehicle. It has the advantages of low investment, high operating efficiency, high safety factor, no energy required, stable and reliable speed control, high safety connection rate, and light and small structure. The wide application of the retarder has played a very effective role in improving the operating efficiency of the marshalling yard, ensuring the safety of transportation operations and personal safety, and realizing the automated hump shunting operation. Therefore, the retarder has a wide range of applications and a large number of uses, and has won the praise of the railway transportation department and the majority of railway staff.

[0003] Chinese patent number CN216332027U provides an automatic deceleration top state detection trolley, which relates to the field of deceleration top detection technology. The detection trolley includes: a frame; a plurality of running mechanisms installed at the bottom of the frame; a pressure measuring mechanism installed on the frame and capable of detecting the oil and gas pressure and installation height of the deceleration top; a track-grabbing mechanism used to offset the oil and gas pressure of the deceleration top and installed on the same side of the frame as the pressure measuring mechanism; a distance-measuring mechanism installed on the same side of the frame as the pressure measuring mechanism and capable of detecting the installation gap of the deceleration top; and a control system, which is used to control the running and automatic stop of the detection vehicle and complete the detection action. After the detection vehicle is started on the road, it can automatically identify the position of the deceleration top, detect the relevant technical parameters of the deceleration top, and transmit the detection data to the mobile terminal through the wireless transmission mode, so as to achieve the purpose of real-time monitoring of the state of the deceleration top. The track-grabbing mechanism can achieve a reliable grip on the track to avoid loosening.

[0004] At present, the existing state detection device for the retarder can monitor each retarder by walking on the rails, but this detection method requires the vehicle to pass through the retarder in order to determine its state. Therefore, for longer lines, this method is more time-consuming, and the above patent cannot detect whether there is looseness between the retarder and the rail. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a state detection device for a retarder, aiming to improve the state detection device for a retarder, in which the detection process is usually too time-consuming and the retarder cannot be detected whether the retarder and the rail are loose.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a state detection device for a deceleration top, comprising a mounting structure and a detection structure.

[0008] The mounting structure includes a fixed block and a detection member, the detection member is arranged on one side of the fixed block, the detection structure includes a pressure measuring member and a clamping member, the clamping member is fixed to the bottom of the pressure measuring member, the pressure measuring member includes a support plate, an electric telescopic rod is fixed inside the support plate, a tension sensor is fixed at the end of the electric telescopic rod, and a sleeve is fixed on the top of the tension sensor.

[0009] In an embodiment of the utility model, a shell is fixed to one side of the fixed block, a sliding cylinder is slidably connected inside the shell, and a top cap is fixed to the top of the sliding cylinder.

[0010] In an embodiment of the utility model, a fixing bolt is fixed on the other side of the fixing block, a fixing nut is threadedly connected to one side of the fixing bolt, and a steel rail is arranged on one side of the fixing bolt.

[0011] In one embodiment of the utility model, the detection component includes a sleeve plate, the sleeve plate is sleeved on one side of the fixing bolt, a sleeve hole is opened on one side of the sleeve plate, a fixing tube is fixed to one side of the sleeve plate, and a guide head is slidably connected inside the fixing tube.

[0013] In one embodiment of the utility model, the clamping member includes a motor, the motor is fixed at the bottom of the sleeve, a gear is fixed to the output shaft end of the motor, a moving bar 1 is meshed on one side of the gear, and the moving bar 1 is slidably connected to the inside of the sleeve.

[0014] In an embodiment of the utility model, an anti-skid pad 1 is fixed on one side of the moving bar 1, a moving bar 2 is meshed on one side of the gear, the moving bar 2 is slidably connected to the inside of the sleeve, and an anti-skid pad 2 is fixed on one side of the moving bar 2.

[0015] The beneficial effect of the utility model is that the utility model obtains a state detection device for a deceleration top through the above-mentioned design. When in use, the electric telescopic rod is first extended to move the sleeve frame upward, and then the motor is used to drive the gear to rotate so that the moving bar 1 and the moving bar 2 are displaced, thereby clamping multiple sliding cylinders through the anti-skid pad 1 and the anti-skid pad 2, and then the electric telescopic rod is retracted. At this time, the tension sensor will transmit the tension value it bears to the background application. If the transmitted value is significantly different from the normal value, it can be proved that some of the deceleration tops have problems, so that it can be judged whether the state of the deceleration top can continue to work. The elastic force of the spring is used to make the guide head press against the rail and the guide plate press against the pressure sensor, so that the value fed back by the pressure sensor can determine whether the fixing nut is loose, thereby judging whether the deceleration top is shaking.

A sliding cylinder 112 is slidably connected inside the housing 111. A top cap 113 is fixed to the top of the sliding cylinder 112. A fixing bolt 114 is fixed to the other side of the fixing block 110. A fixing nut 115 is threadedly connected to one side of the fixing bolt 114.

The sleeve plate 121 plays a supporting role. The sleeve plate 121 is sleeved on one side of the fixing bolt 114. The sleeve plate 121 A sleeve hole 122 is provided on one side, and the sleeve hole 122 facilitates the sleeve plate 121 to be sleeved onto the fixing bolt 114. A fixing tube 123 is fixed on one side of the sleeve plate 121, and the fixing tube 123 serves to limit the moving direction of the guide head 124 and the guide plate 126. The guide head 124 is slidably connected inside the fixing tube 123, and a spring 125 is fixed on the end of the guide head 124. The spring 125 can apply pressure to the pressure sensor 127 through elastic force, and a guide plate 126 is fixed on the end of the spring 125. A pressure sensor 127 is fixed on one side of the guide plate 126. The different values ​​fed back by the pressure sensor 127 can determine whether the fixing nut 115 is loose.

[0027] See also Figure 1 and Figure 4-5 The detection structure 200 includes a pressure measuring piece 210 and a clamping piece 220. The clamping piece 220 is fixed at the bottom of the pressure measuring piece 210. The pressure measuring piece 210 includes a support plate 211. An electric telescopic rod 212 is fixed inside the support plate 211. A tension sensor 213 is fixed at the end of the electric telescopic rod 212.

[0028] The clamping member 220 includes a motor 221, which is fixed at the bottom of the sleeve frame 214. A gear 222 is fixed to the output shaft end of the motor 221. A moving bar 223 is meshed on one side of the gear 222. A tooth is set on one side of the moving bar 223. The moving bar 223 is slidably connected to the inside of the sleeve frame 214.

[0029] Specifically, the working principle of the state detection device for the deceleration top is as follows: when in use, first insert the fixing bolt 114 through the steel rail 116, then put the sleeve plate 121 on one side of the fixing bolt 114 through the sleeve hole 122 on the sleeve plate 121, and finally screw the fixing nut 115 on the fixing bolt 114 to complete the installation of the equipment. At this time, the elastic force of the spring 125 makes the guide head 124 press against the steel rail 116, and the guide plate 126 will squeeze the pressure sensor 127 against the inner wall of the fixed tube 123, so that the pressure sensor 127 is subjected to pressure, so it can transmit the value to the background. If the value transmitted by the pressure sensor 127 changes significantly, it proves that the elastic force of the spring 125 is further released, so that the pressure sensor 127 is no longer subjected to a large squeeze, so it can be judged that the fixing nut 115 is loose. , so that it can be determined that the deceleration top is in a non-fixed state, and the extension of the electric telescopic rod 212 is used to make the sleeve frame 214 move up, and then the motor 221 is started, so that the gear 222 drives the moving bar 1 223 and the moving bar 2 225 to move respectively, so that the anti-skid pad 1 224 and the anti-skid pad 2 226 can clamp the sliding cylinder 112, and then the electric telescopic rod 212 is retracted. At this time, the sliding cylinder 112 will passively move synchronously, but under the reverse pressure of the sliding cylinder 112, the electric telescopic rod 212 will be subject to a certain resistance when it is retracted, so that the resistance will be detected by the tension sensor 213, and the detected data will be fed back to the background, and then the background can compare with the normal data to determine whether the several deceleration tops controlled by the sleeve frame 214 have a fault, so as to determine whether the state of the deceleration top is good or bad.

[0030] It should be noted that the specific model and specifications of the motor 221 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0031] The power supply and principle of the motor 221 are clear to those skilled in the art and will not be described in detail here.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
