[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Embodiment: A device for measuring the distance between sleepers in railway engineering, such as Figures 1-4As shown, it includes a measuring frame 1, the bottom end surface of the measuring frame 1 is flat and can be placed on two groups of sleepers, one end of the measuring frame 1 is integrally formed with an endpoint clamping part 3, and the other end is integrally formed with a free end support part 4, and a measuring end plate 5 fixed in a horizontal position is provided below the endpoint clamping part 3, and the end of the measuring frame 1 close to the free end support part 4 is provided with a movable measuring tail plate 6, which can be moved in the measuring frame 1 to fit the adjacent sleepers to measure the distance between the two groups of sleepers, and a lifting rod 2 is installed on the side of the measuring frame 1 close to the endpoint clamping part 3, the lifting rod 2 is vertically upward and a handle 19 is fixed on the top of the lifting rod 2. When measuring, the measurement personnel can hold the handle 19 upright and operate the entire device to measure the distance between the sleepers while standing, which greatly reduces the damage to the waist caused by the measurement.

[0027] Furthermore, the distance between the end point clamping portion 3 and the free end support portion 4 is sixty-five centimeters, and the conventional sleeper spacing is between fifty-two and sixty centimeters. Therefore, when the end point clamping portion 3 coincides with one group of sleepers, the free end support portion 4 will be placed behind the other group of sleepers. By utilizing the flat surface of the bottom surface of the measuring frame 1 and pressing down the measuring frame 1 through the lifting rod 2, the measuring frame 1 can remain in contact with the sleepers during measurement.

[0028] Furthermore, the measuring frame 1 is divided from the middle into a driving part 11 located below the lifting rod 2 and a measuring part 12 on the other side, wherein the driving part 11 is provided with a component for driving the movement of the measuring tail plate 6, and the measuring part 12 is provided with a component for ensuring the stable translation of the measuring tail plate 6 and reading the measurement value.

[0029] Specifically, a motor 13 is fixedly installed in the driving part 11, and a measuring part 12 and a screw rod 14 are fixedly installed at the output end of the motor 13. The screw rod 14 is a screw rod 14 with an external thread. The screw rod 14 extends into the measuring part 12 and a slider 15 is threadedly connected to the screw rod 14. The slider 15 is fixedly connected to the measuring tail plate 6. The measuring frame 1 is provided with a groove for accommodating the sliding of the slider 15 at a position corresponding to the top of the measuring part 12. When the motor 13 rotates, it drives the screw rod 14 to drive the slider 15 to move back and forth along the measuring part 12 to measure the distance between the sleepers. A scale plate 16 is fixedly installed above the measuring part 12. The initial end mark number of the scale plate 16 is the distance from the measuring end plate 5 to the initial end of the scale plate 16. Since the distance range of the sleepers is between fifty-two and sixty centimeters, it is actually only necessary to read the value within the variable range.

[0030] A battery pack 17 is fixedly installed in the driving unit 11 for supplying power to the motor 13 .

[0031] In order to ensure that the measuring tail plate 6 can stop in time during measurement, a pressure sensor 18 is fixedly installed on the measuring tail plate 6. When the measuring tail plate 6 is in contact with the sleeper, the pressure sensor 18 is compressed and generates an electrical signal to turn off the motor 13. At this time, the distance between the two groups of sleepers is 0. In other embodiments, the pressure sensor 18 can also be installed on the measuring end plate 5 and the rear end of the motor 13. When a change in the pressure signal at the corresponding position is detected, the motor 13 is turned off.

[0032] Furthermore, a switch button 20 is fixedly mounted on the handle 19 , and the switch button 20 is electrically connected to the motor 13 . When the switch button 20 is pressed, the motor 13 rotates in the forward direction, pushing the measuring tail plate 6 toward the sleeper for measurement.

[0033] Furthermore, a clamping plate 7 is fixedly installed below the end point clamping portion 3, and the clamping plate 7 and the measuring end plate 5 can be clamped to the sleeper to perform initial positioning of the entire measuring device, ensuring that the measuring end plate 5 is located at the edge of the sleeper, and ensuring that the distance between the measuring end plate 5 and the measuring tail plate 6 is the maximum distance between the two groups of sleepers.

[0034] Furthermore, in order to facilitate adaptive changes to sleepers of different widths, a joint plate 8 is fixedly installed between the measuring end plate 5 and the clamping plate 7, and a slide rod 9 is detachably installed on the joint plate 8. The slide rod 9 is fixedly installed in the end point clamping portion 3, and the slide rod 9 and the joint plate 8 are detachably connected by a fastener 21, which can be a screw.

[0035] Furthermore, in some cases, the ballast on the side of the sleeper is paved at different heights. Therefore, in order to better adapt the measuring end plate 5 and the clamping plate 7 to the actual ballast height during measurement, the slide bar 9 is movably installed on the end point clamping portion 3 and can slide up and down in the end point clamping portion 3. The outer wall of the slide bar 9 is sleeved with a spring 10, so that the joint plate 8 can slide up and down as needed to adapt to the ballast height.

[0036] Furthermore, in order to better carry it, a bracket 22 is fixedly installed on the top of the measuring frame 1, and a rotating shaft 23 is fixedly installed between the brackets 22. The lifting rod 2 is sleeved on the rotating shaft 23 and the end of the lifting rod 2 close to the rotating shaft 23 is provided with a curved surface to form a rotating side 24, so that the lifting rod 2 can be folded around the measuring frame 1 on the measuring frame 1 for easy carrying.

[0037] The working principle of the present invention is as follows: when in use, the lifting rod 2 is folded and unfolded on the measuring frame 1, so that the lifting rod 2 and the measuring frame 1 are perpendicular to each other. Because the lifting rod 2 is located in the direction of the measuring frame 1 close to the end point clamping part 3, and the driving part 11 is also concentrated below the lifting rod 2, the center of gravity of the entire equipment is located below the handle 19, which saves effort in operation. With the assistance of the lifting rod 2, there is no need to bend over or squat to measure.

[0038] During specific measurement, hold the handle 19, lift the equipment, and clamp the measuring end plate 5 and the clamping plate 7 on the sleeper. Under the action of gravity, the plane below the measuring frame 1 is placed between the two groups of sleepers. At this time, press and hold the switch button 20, and the motor 13 drives the screw rod 14 to rotate, driving the slider 15 and the measuring tail plate 6 to slide along the edge of the scale plate 16 until the pressure sensor 18 on the measuring tail plate 6 touches the other group of sleepers, and the distance between the sleepers is measured.

[0039] Through the cooperation of the slide bar 9 and the spring 10, when the ballast of the sleeper is uneven, the height of the connection between the clamping plate 7 and the measuring end plate 5 and the sleeper can be adjusted, and the lifting rod 2 can be operated to keep the measuring frame 1 in a stable state to perform measurements between the sleepers.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
