Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation training medical device technology, specifically to a correction device for the sliding track of an H-rail transfer machine. Background Technology
[0002] In ceiling-mounted track-type transfer or walking training devices, the H-shaped track is a common structure. This track consists of two parallel tracks and one sliding track. The two parallel tracks are connected and fixed to the roof by mounting rods. These two parallel tracks are stationary, while the sliding track slides along these two parallel fixed tracks, thereby moving the user through the transfer machine for training.
[0003] However, in real-world scenarios, fixed tracks are typically composed of multiple track segments, especially in the case of very long fixed tracks. During the track splicing process, although workers adjust the horizontal ends of multiple tracks to achieve a relatively level state, ensuring that the fixed tracks have the same height while maintaining parallelism is quite difficult, especially ensuring parallelism at the track joints. Therefore, misalignment or poor parallelism may occur at the joints of the fixed tracks. This can cause users to experience a noticeable jamming sensation when moving to the joint, which is not only detrimental to user training but may also pose potential safety risks. Summary of the Invention
[0004] This invention addresses the problem of jamming or uneven sliding of existing sliding tracks when they reach the joint with fixed tracks by providing a correction device for the sliding track of an H-rail transfer machine. The correction device in this invention allows for a certain degree of extension and retraction of the sliding track's length, thereby preventing jamming caused by misalignment of the tracks when they reach the joint with the fixed tracks.
[0005] The technical solution of this utility model is: a correction device for the sliding track of an H-rail shifting machine. The correction device is at least one and disposed on the sliding track. The sliding track is divided into at least two segments and adjacent segments are connected by the correction device. The correction device includes a fixed unit and a moving unit. The fixed unit is fixedly connected to the sliding track segment on the left side of the correction device, and the moving unit is fixedly connected to the sliding track segment on the right side of the correction device. The distance between the moving unit and the fixed unit along the length of the sliding track can be changed, so that the length of the sliding track can be extended or retracted.
[0006] Using the above scheme, two adjacent sliding track segments are connected by a correction device, and the distance between the fixed unit and the moving unit in the correction device can be changed, so that the sliding track has a certain degree of flexibility. Thus, when the sliding track slides to the splicing point of the fixed track, the sliding track can achieve a certain degree of expansion and contraction according to the actual situation, thereby adapting to the deviation caused by the non-parallel splicing of the tracks, and thus avoiding the user from feeling stuck during training.
[0007] Furthermore, the fixed unit and the movable unit are respectively a fixed bracket and a movable bracket. The fixed bracket and the movable bracket are each provided with at least one corresponding through hole. A correction shaft passes through the through hole. Both ends of the correction shaft that pass through the fixed bracket and the movable bracket are fixed with blocks.
[0008] In the above-mentioned further scheme, the fixed bracket is fixed to its left sliding track section, the movable bracket is fixed to its right sliding track section, the correction shaft is inserted into the fixed bracket and the movable bracket, and the two ends of the correction shaft are provided with blocks, so that the movable bracket can slide left and right along the correction shaft, thereby realizing the extension and retraction of the sliding track length.
[0009] Furthermore, the correction shaft is fixedly connected to the fixed bracket, enabling the fixed bracket to provide stable support for the sliding of the movable bracket, thereby ensuring the stability of the sliding track's extension and retraction.
[0010] Furthermore, a sliding sleeve is fixedly installed inside the through hole of the movable bracket, and the sliding sleeve is sleeved outside the correction shaft, so that the movable bracket can slide more smoothly.
[0011] Furthermore, a shifting machine is slidably disposed on the sliding track, and the shifting machine moves on the sliding track via at least one roller. The distance between the fixed unit and the moving unit does not affect the movement of the roller on the sliding track.
[0012] Furthermore, the maximum distance between the fixed unit and the moving unit in one of the correction devices is H1, and the arc length on the circle corresponding to the maximum diameter of a single roller is H2 when the central angle of the circle is 5 degrees. H1 is less than or equal to H2, and H2 is not limited to the arc length on the circle corresponding to the maximum diameter of a single roller when the central angle of the circle is 5 degrees. It is only necessary to ensure that when the roller of the shifting machine moves to the correction device on the sliding track, it will not get stuck due to the gap between the fixed unit and the moving unit, so that the shifting machine can move more smoothly on the entire sliding track.
[0013] The beneficial effects of this utility model through the above technical solution are as follows:
[0014] 1. In this utility model, two adjacent sliding rail segments are connected by a correction device, and the distance between the fixed unit and the moving unit in the correction device can be changed, so that the sliding rail has a certain degree of flexibility. Thus, when the sliding rail slides to the splicing point of the fixed rail, the sliding rail can achieve a certain degree of expansion and contraction according to the actual situation, thereby adapting to the deviation caused by the non-parallel splicing of the rails, and thus avoiding the user from feeling stuck during training.
[0015] 2. In a further embodiment of this utility model, the setting of the correction shaft provides a moving guide for the movable support, and the correction shaft is fixedly connected to the fixed support, providing stable support for the movement of the movable support, thereby ensuring the stability of the sliding track extension and retraction.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0021] Example 1:
[0022] like Figure 1 and Figure 2 As shown, a correction device for the sliding track of an H-rail shifting machine is disclosed. The correction device 1 is disposed on the sliding track 2. The sliding track 2 is divided into at least two segments, and adjacent segments are connected by the correction device 1. The sliding track 2 slides on a fixed track 8. The correction device 1 includes a fixed unit 3 and a moving unit 4. The fixed unit 3 is fixedly connected to the left side of the sliding track 2 segment of the correction device 1, and the moving unit 4 is fixedly connected to the right side of the sliding track 2 segment of the correction device 1. The distance between the moving unit 4 and the fixed unit 3 along the length direction of the sliding track 2 can be changed, so that the length of the sliding track 2 can be extended or retracted.
[0023] In this embodiment, two adjacent sliding rails 2 are connected by a correction device 1, and the distance between the fixed unit and the moving unit in the correction device can be changed, so that the sliding rail 2 has a certain degree of flexibility. When the sliding rail 2 slides to the splicing point of the fixed rail, the sliding rail 2 can achieve a certain degree of expansion and contraction according to the actual situation, thereby adapting to the deviation caused by the non-parallel splicing of the rails, and thus avoiding the user from feeling stuck during training.
[0024] In one possible implementation, the fixed unit 3 and the moving unit 4 are respectively a fixed bracket and a moving bracket. Both the fixed bracket and the moving bracket are square blocks, and the bottom of the fixed bracket and the moving bracket are higher than the bottom of the sliding track 2, so as to avoid the fixed bracket and the moving bracket affecting the sliding of the shifting machine 9 on the sliding track 2. The fixed bracket and the moving bracket are respectively provided with four corresponding through holes, and the correction shaft 5 is inserted through the through holes. Both ends of the correction shaft 5 that pass through the fixed bracket and the moving bracket are fixed with a stop block 6, so that the moving bracket can slide left and right along the correction shaft 5.
[0025] As one possible implementation, the correction shaft 5 is fixedly connected to the fixed bracket, so that the fixed bracket can provide stable support for the sliding of the movable bracket, thereby ensuring the stability of the extension and retraction of the sliding track 2.
[0026] As one possible implementation, a sliding sleeve 7 is fixedly installed inside the through hole of the movable bracket, and the sliding sleeve 7 is sleeved outside the correction shaft 5, so that the movable bracket can slide more smoothly.
[0027] As one possible implementation, a shifting machine 9 is slidably disposed on the sliding track 2. The shifting machine 9 moves on the sliding track 2 via at least one roller, and the distance between the fixed unit 3 and the moving unit 4 does not affect the movement of the roller on the sliding track 2.
[0028] In this embodiment, the distance between the fixed bracket and the movable bracket in one of the correction devices 1 is H1, and the arc length on the circle corresponding to the maximum diameter of a single roller is H2 when the central angle of the circle is 5 degrees. H1 is less than or equal to H2, and according to the actual application scenario, H2 is not limited to the arc length on the circle corresponding to the maximum diameter of a single roller when the central angle of the circle is 5 degrees. It is only necessary to ensure that when the roller of the shifting machine 9 moves to the correction device 1 on the sliding track 2, it will not get stuck due to the gap between the fixed unit 3 and the movable unit 4, so that the shifting machine can move more smoothly on the entire sliding track 2.
[0029] In this embodiment, when used:
[0030] The sliding track 2 slides along the length of the fixed track 8. When the sliding track 2 slides to the splice of the fixed track 8, if there is any skew or misalignment at the splice of the fixed track 8, the sliding track 2 will slide to that point. Due to the limit between the two ends of the sliding track 2 and the fixed track 8, the moving bracket in the correction device 1 on the sliding track 2 will move left and right relative to the fixed bracket along the correction axis 5. This allows the length of the sliding track 2 to be extended or retracted, thus smoothly passing through the splice of the fixed track 8. Furthermore, in this utility model, because the distance between the fixed bracket and the moving bracket in a single correction device 1 is limited, the shifting machine 9 will not get stuck when it slides on the sliding track 2 to the correction device 1.
[0031] Example 2:
[0032] The technical solution in this embodiment is the same as that in Embodiment 1, except that:
[0033] like Figure 3 As shown, the correction device 1 has three units on the sliding track 2, which can be used in scenarios where the width between the fixed tracks 8 is relatively wide, or where the skew at the joint of the fixed track 8 segments may be large due to the limitations of the installation environment.
