Description

Technical Field

[0001] The utility model relates to the technical field of track mobile equipment, in particular to a rolling stroke measuring device. Background Art

[0002] The measurement and real-time monitoring of the moving distance of mobile equipment based on tracks or fixed walking routes are of great significance to all aspects of the use of the entire equipment. At present, the measurement of the moving distance of most mobile equipment uses optical detection mechanisms or high-precision mechanical meshing structures similar to gear racks. Optical detection relies on highly recognizable marks and visual equipment recognition, which are located at the fixed end and the mobile end respectively, and read the position information by identifying the corresponding marks. The mechanical meshing structure drives the gear to rotate through the rack, and then uses other equipment to read the number of rotations of the gear to read the travel distance information.

[0003] At present, the use of optical detection equipment has high requirements for the use environment. Optical equipment is difficult to work normally in the open air or in dusty environments. For equipment with unstable moving trajectories, the accuracy of visual recognition will decrease, and it is very easy to cause reading failures. The use of mechanical meshing structures is first of all very expensive. For some large equipment with long moving distances, the specifications and dimensions of the rack will increase a lot, and the hardware cost will increase greatly. At the same time, for scenes with unstable moving trajectories, bumps, shakes, and emergency stops, the high-precision meshing structure of the gear rack will be easily damaged, resulting in reduced measurement accuracy.

In this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0023] The inventor of this solution has found that in the prior art, the use of optical detection equipment has high requirements for the use environment. It is difficult for optical equipment to work normally in the open air or in a dusty environment. In addition, for equipment with an unstable moving trajectory, the accuracy of visual recognition will decrease, and it is very easy to cause reading failure. The use of a mechanical meshing structure is first of all very expensive. For some large equipment with long moving distances, the specifications and dimensions of the rack will increase a lot, and the hardware cost will increase greatly. At the same time, for scenes with unstable moving trajectories, bumps, shakes, and emergency stops, the high-precision meshing structure of the gear rack will be easily damaged, resulting in a decrease in measurement accuracy. This embodiment provides the following solution:

[0024] like Figure 1 to Figure 2 As shown, this embodiment provides a rolling stroke measuring device, including a device body 1, the device body 1 is provided with a rotatable rolling body mounting seat 2 and an elastic mechanism 3 for applying a preload force to the rolling body mounting seat 2, the rolling body mounting seat 2 is installed with a rotatable rolling body 4 and an angle detector 5 for measuring the rotation angle of the rolling body 4.

[0025] It should be noted that the outer surface of the rolling body 4 contacts the fixed end surface 9, and the elastic mechanism 3 continuously applies a preload force to the rolling body 4, which can keep the rolling body 4 in contact with the fixed end surface 9. As the mobile terminal device moves, the rolling body 4 rolls along the fixed end surface 9, and the angle detector 5 detects the change in the rotation angle of the rolling body 4, records the accumulated number of rotations in real time and outputs a signal, thereby achieving real-time measurement and tracking of the moving distance. When there are unevenness, protrusions or foreign objects on the fixed end surface 9, the elastic mechanism 3 can play a role in pressing down, buffering and rebounding the rolling body 4, so as to avoid virtual contact and improve detection accuracy. Therefore, the device can be used under conditions of extreme temperature, extreme air pressure and extreme humidity generated by severe weather or working environment.

[0026] Specifically, the rolling element mounting seat 2 includes a first fixing plate 21 and a second fixing plate 22, and the first fixing plate 21 and the second fixing plate 22 are symmetrically and rotatably connected to the two sides of the device body 1 through the hinge pin hole 8, and the hinge pin hole 8 and the device body 1 are connected by a pin to form a hinge structure. The hinge pin hole 8 is symmetrically arranged at the top end of the first fixing plate 21 and the second fixing plate 22, so that the rolling element mounting seat 2 as a whole can have a better downward force and improve the overall stability. The two ends of the rolling element 4 are connected to the first fixing plate 21 and the second fixing plate 22 through the bearing 6 respectively.

[0027] The angle detector 5 is an angle sensor, and a detection shaft 51 is provided in the detection hole of the angle detector 5. The angle detector 5 is installed on the outer side of the first fixed plate 21. The detection shaft 51 passes through the first fixed plate 21, the rolling body 4 and the second fixed plate 22 in sequence, and is connected to one end of the rolling body 4 through the stop plate 7.

[0028] It can be understood that the central axis of the detection shaft 51 is the same as the central axis of the rolling body 4 . When the rolling body 4 rotates, the detection shaft 51 rotates together with the rolling body 4 , so that the rotation angle change of the rolling body 4 can be detected.

[0029] The elastic mechanism 3 includes an elastic seat 31 and an elastic member 32. A rebound space is left between the elastic seat 31 and the device body 1. The elastic member 32 is a spring. Both sides of the elastic seat 31 are respectively connected to the first fixing plate 21 and the second fixing plate 22. The elastic seat 31 and the device body 1 are respectively provided with corresponding elastic grooves 33. The elastic member 32 is arranged in the elastic groove 33. The device body 1 is provided with a threaded hole 11 corresponding to the elastic groove 33.

[0030] It is understandable that after the screw is screwed into the threaded hole 11, the spring is compressed, which can play the function of adjusting the preload force.

[0031] The elastic seat 31 is provided with a first fixing through hole 311 and a positioning pin hole 312, and the first fixing plate 21 and the second fixing plate 22 are respectively provided with a second fixing through hole 23 corresponding to the first fixing through hole 311, the fixing through hole 311 is located in the lateral middle position of the elastic seat 31, and the positioning pin hole 312 is located below the fixing through hole 311.

[0032] It should be noted that the second fixing through hole 23 on the first fixing plate 21 is a threaded through hole, or the second fixing through hole 23 on the second fixing plate 22 is a threaded through hole, and the elastic seat 31 is connected to the first fixing plate 21 and the second fixing through hole 23 by inserting bolts into the first fixing through hole 311 and the second fixing through hole 23, and the elastic seat 31 is positioned between the first fixing plate 21 and the second fixing plate 22 by the positioning pin hole 312.

[0033] In a specific implementation, when the rolling body 4 rolls on the fixed end surface 9, the detection shaft 51 rotates together with the rolling body 4, so that the angle detector 5 detects the change in the rotation angle of the rolling body 4, records the accumulated number of rotations in real time and outputs a signal, thereby achieving real-time measurement and tracking of the moving distance. When the rolling body 4 encounters jitter, unevenness, protrusions or foreign objects during the rolling process, the elastic mechanism 3 can play a role in pressing down and buffering the rolling body 4 to avoid virtual contact and improve the detection accuracy.

[0034] In summary, the embodiments of the utility model provide a rolling stroke measuring device, which calculates the number of rotations of the rolling body by setting an angle sensor to obtain the travel distance, thereby making it adaptable to most severe weather conditions. An elastic mechanism is provided to give the rolling body a buffering force, thereby making it adaptable to environments with uneven contact surfaces. The device has a wider range of uses, lower overall production costs, and longer service life.
