[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-6 This utility model discloses a quick-installation and quick-disassembly device for a track axle counter, comprising: a track axle counter 1, a lead screw base 14, a hydraulic cylinder limiting block 7, a first T-shaped base 2, and a second T-shaped base 5. An oil circuit valve island 15 is fixedly installed on the top of both the first T-shaped base 2 and the second T-shaped base 5. An oil tank 8 is fixedly installed on the top of the oil circuit valve island 15. A single-acting hydraulic cylinder 13 is provided at one end of the oil circuit valve island 15. A through hole is provided on the outer wall of the hydraulic cylinder limiting block 7, and a single-acting hydraulic cylinder 13 is fixedly installed on one side of the outer wall of the hydraulic cylinder limiting block 7. A single-acting hydraulic cylinder 13 is installed on the outer wall of one end of the oil circuit valve island 15. It passes through the through hole opened on the outer wall of the hydraulic cylinder limit block 7 and extends out of the interior of the through hole. A first oil pipe joint 10 is fixedly installed on the side wall of the oil tank 8. An oil pipe 9 is fixedly installed on the other end of the first oil pipe joint 10. A second oil pipe joint 11 is fixedly installed on the other end of the oil pipe 9. A two-position three-way solenoid directional valve 12 is fixedly installed on the other end of the second oil pipe joint 11. The two-position three-way solenoid directional valve 12 is located on one side of the oil circuit valve island 15.

[0019] In the quick-installation and quick-disassembly device for the track axle counter of this utility model, the hydraulic oil in the oil tank 8 is pressurized by the hydraulic pump, and the high-pressure oil is delivered to the oil pipe 9 through the first oil pipe joint 10, and then to the two-position three-way solenoid valve 12 through the second oil pipe joint 11. The two-position three-way solenoid valve 12 is energized and reversed, and the high-pressure oil is distributed to the single-acting hydraulic cylinder 13 through the internal flow channel of the oil circuit valve island 15. The single-acting hydraulic cylinder 13 extends under the push of the hydraulic oil, and its piston rod passes through the through hole of the hydraulic cylinder limiting block 7 to limit the maximum extension stroke, so as to avoid excessive compression of the track, until it is tightly pressed against the side of the track. The single-acting hydraulic cylinders 13 on both sides exert force synchronously to form a symmetrical clamping force, which stably fixes the first T-shaped base 2 and the second T-shaped base 5 on both sides of the track. The track axle counter 1 is pre-installed on the first T-shaped base 2. With the positioning and clamping of the base, the track is accurately assembled to ensure the stability of the detection position. When disassembling, the hydraulic pump in the oil tank 8 is turned off first to stop the high-pressure oil supply. Then, the two-position three-way solenoid directional valve 12 is de-energized and reversed. The oil in the single-acting hydraulic cylinder 13 flows back to the oil tank 8 through the oil circuit valve island 15 and the oil pipe 9. The piston rod retracts under the reaction force of the track and gets out of the track constraint.

[0020] A lead screw fixing plate 6 is fixedly installed at one end of the lead screw base 14. A lead screw 4 is rotatably installed on the outer wall of the lead screw fixing plate 6. A drive motor 3 is fixedly installed on the side wall of the first T-shaped base 2. A second through hole 18 is opened on the outer wall of the first T-shaped base 2. The output shaft of the drive motor 3 extends into the interior of the second through hole 18. The other end of the lead screw 4 is fixedly installed on the output shaft of the drive motor 3. A mounting groove 19 is opened on the lower surface of the first T-shaped base 2. The lead screw base 14 is fixedly connected to the inner wall of the mounting groove 19. The lead screw 4 passes through the interior of the second through hole 18. The timing shaft 1 is fixedly installed on the side wall of the first T-shaped base 2. The lower surface of the second T-shaped base 5 is provided with a stroke groove 16. The lead screw base 14 is slidably connected to the inner wall of the stroke groove 16. The outer wall of the second T-shaped base 5 is provided with a first through hole 17. The inner wall of one end of the first through hole 17 is fixedly installed with a lead screw nut 20. The outer wall of the lead screw 4 is provided with an external thread raceway. The inner wall of the lead screw nut 20 is provided with an internal thread raceway that matches the external thread raceway. The lead screw 4 and the lead screw nut 20 are connected by rolling balls. The lead screw 4 passes through the interior of the first through hole 17.

[0021] In the quick-installation and quick-disassembly device for track axle counters described in this utility model, the device achieves precise spacing adjustment between the first T-shaped base 2 and the second T-shaped base 5 through a screw drive system. A screw fixing plate 6 fixed to one end of the screw base 14 provides rotational support for the screw 4. One end of the screw 4 is fixed to the output shaft of the drive motor 3 on the first T-shaped base 2. The output shaft of the drive motor 3 passes through the second through hole 18 and connects to the screw. Since the first T-shaped base 2 is fixed to the screw base 14 through the lower surface mounting groove 19, its position remains unchanged. The second T-shaped base 5 is slidably connected to the screw base 14 through the lower surface stroke groove 16, and the screw nut 20 in its first through hole 17 connects to the screw 4 via ball bearings. A suitable threaded rolling connection is formed. When the drive motor 3 starts, its output shaft drives the lead screw 4 to rotate on the lead screw fixing plate 6. The rotational motion of the lead screw is converted into linear motion through the cooperation of the ball and nut, driving the second T-shaped base 5 to slide along the lead screw base 14 until the distribution range of the single-acting hydraulic cylinders 13 on both sides matches the width of the track to be installed, thus completing the track adaptation. When disassembly is required, the drive motor 3 rotates in the opposite direction, driving the lead screw 4 to rotate in the opposite direction. Through the lead screw nut 20, the second T-shaped base 5 is driven to slide along the lead screw base 14 away from the first T-shaped base 2, widening the distance between the two sides, so that the entire device is removed from the track, and finally the track axle counter 1 is quickly disassembled.

[0022] Working principle: First, place the quick-installation and quick-release device for the track axle counter on the side of the track. Then, start the drive motor 3. The output shaft of the drive motor 3 drives the lead screw 4 to rotate. A lead screw nut 20 is installed on the outer wall of the lead screw 4. As the lead screw 4 rotates, it drives the lead screw nut 20 to move. The lead screw nut 20 then drives the second T-shaped base 5 to move closer to the first T-shaped base 2. At this point, the drive motor 3 can be stopped, completing the adaptation to the track. Then, start the hydraulic pump installed inside the oil tank 8. The hydraulic pump draws oil from the oil tank 8. The oil is transported to the oil circuit valve island 15 through the oil pipe 9 and distributed to the two-position three-way solenoid directional valve 12. By controlling the energization and reversing of the two-position three-way solenoid directional valve 12, the oil enters the rear of the single-acting hydraulic cylinder 13 through the oil pipe 9. The piston rod of the single-acting hydraulic cylinder 13 is pushed out of the cavity until it is tightly pressed against the side of the track, completing the installation of the track axle counter quick-installation and quick-removal device on the track. At this time, the track axle counter 1 is stably fixed beside the track along with the first T-shaped base 2, completing the installation. When disassembly is required, the hydraulic pump inside the oil tank 8 is turned off, and the two-position three-way solenoid valve 12 is de-energized and reversed. The oil in the rear cavity of the single-acting hydraulic cylinder 13 flows back to the oil tank 8 through the oil pipe 9 and the two-position three-way solenoid valve 12. The piston rod of the single-acting hydraulic cylinder 13 retracts. Similarly, the drive motor 3 is reversed to make the second T-shaped base 5 move in the opposite direction, increasing the distance between the second T-shaped base 5 and the first T-shaped base 2, so that the device is freed from the track constraint. The device is then removed, completing the disassembly.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
