Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a head steering auxiliary device for a ceiling track machine. Background Technology

[0002] Patients with stroke and other neurological diseases often have hemiplegic symptoms. Walking training is an important part of restoring the walking ability of hemiplegic patients. This includes patients who have difficulty walking due to accidents such as car accidents. In addition to surgery and drug treatment, scientific walking training is also necessary.

[0003] Weight-loss gait training is a training method used to restore lower limb strength and walking ability. It reduces part or all of the patient's weight through suspension, allowing the patient to maintain balance and perform gait training, so that patients with insufficient lower limb strength can gradually regain their ability to walk.

[0004] Most existing weight-loss gait training methods use overhead rail suspension systems. With the cooperation of a top-mounted overhead rail machine head and track system, along with slings and poles, the patient is suspended in the air with their feet on the ground. The software algorithm of the overhead rail system then performs precise weight-loss gait training for the patient, thereby helping the patient gradually recover leg muscle strength. At the same time, by using specially designed slings with different functions, the patient can be transferred, moved, used for toileting, bathing, standing training, balance training and other rehabilitation treatments and training processes can be completed, minimizing the risk of falls for the patient and the workload of rehabilitation therapists.

[0005] Because it is used for rehabilitation training of patients with movement disorders, it requires high stability during walking. The current overhead track motor head has a certain length, that is, there is a gap between the front and rear wheels of the part of the motor head located inside the overhead track. When the motor head moves to a turning position, in order to meet the turning requirements, the internal space of the overhead track is wider than other parts of the overhead track at the turning point. As a result, when the motor head moves to this position, there will be a certain lateral displacement or swaying, resulting in poor movement stability of the overhead track motor head, affecting the rehabilitation training effect of the patient, and even posing a risk of the patient falling. Summary of the Invention

[0006] This invention addresses the problem that existing overhead track rehabilitation machines have a certain length, meaning there is a gap between the front and rear wheels of the machine head located on the overhead track. When the machine head moves to a turning position, to meet the turning requirements, the internal space at the turning point of the overhead track is wider than that at the straight track position. Consequently, when the machine head reaches this position, there is a certain lateral displacement or swaying, resulting in poor movement stability of the overhead track rehabilitation machine head, affecting the patient's rehabilitation training effect, and even posing a risk of patient falls. This invention provides an overhead track rehabilitation machine head turning assistance device, which buffers the vertical, lateral, and forward and backward movement of the overhead track rehabilitation machine head during its movement, ensuring the smoothness of the overhead track rehabilitation machine head during movement and turning, and improving the safety of rehabilitation training.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A steering assist device for a ceiling track machine head is installed on both the front and rear sides of the machine head inside the ceiling track. It includes a mounting frame, with two wheel frames hinged to one side of the mounting frame. Multiple first wheels are mounted on the wheel frames, each abutting against one of the inner side walls of the ceiling track. First and second buffer components are respectively installed between the wheel frames and between the wheel frames and the mounting frame, providing buffering in the machine head's traveling direction and on both sides. A third buffer component is installed above the mounting frame, and a second wheel is installed above the third buffer component, abutting against the top inner side of the ceiling track. The third buffer component provides vertical buffering for the machine head. Through the cooperation of the first, second, and third buffer components, the machine head is buffered and positioned in multiple directions, effectively improving its traveling stability.

[0009] Preferably, the mounting frame includes a first mounting plate, a second mounting plate, and a third mounting plate. The first mounting plate has a second mounting plate and a third mounting plate fixedly mounted on one side, with corresponding upper and lower mounting plates. A wheel frame is hinged between the ends of the second mounting plate and the ends of the third mounting plate, and the wheel frame swings to allow the first wheel to move in coordination with the internal gap of the ceiling track.

[0010] Preferably, the first buffer includes a first spring, and the first spring is fixedly disposed between the two wheel frames to buffer the swing of the two wheel frames.

[0011] Preferably, the second buffer includes a second spring, and a second spring is fixedly provided between the end of each wheel frame near the corresponding first wheel and the first mounting plate, so as to buffer the swing of the wheel frame.

[0012] Preferably, the third buffer includes a telescopic rod and a third spring sleeved on the telescopic rod. The lower end of the telescopic rod is fixedly connected to a mounting bracket, and the upper end is equipped with a second wheel. The third spring is disposed between the second wheel and the mounting bracket.

[0013] Preferably, a fixing member is provided on the side of the mounting frame away from the wheel frame for connecting the mounting frame and the machine head.

[0014] Preferably, the fixing component includes a fixing plate with a central opening and bolts disposed on the fixing plate. The fixing plate is fixedly connected to the mounting bracket, and the fixing plate and the machine head are fixedly connected by bolts.

[0015] The beneficial effects of this utility model through the above technical solution are as follows:

[0016] 1. This utility model uses a first buffer, a second buffer, and a third buffer to buffer and absorb vibrations in the vertical, forward and backward, and lateral directions during the movement of the machine head, thereby effectively improving the stability of the machine head during movement and ensuring the safety of patient rehabilitation training.

[0017] 2. This utility model uses a hinged wheel frame and the cooperation of a first buffer and a second buffer to achieve the effect that when the machine head turns, the resultant force exerted by the first buffer and the second buffer on the machine head cancels out the centrifugal force on the machine head. When the machine head undergoes lateral displacement or swaying, it is buffered to ensure the stability of the overhead track machine head when turning.

[0018] 3. When the present invention is in operation, the first spring is in a compressed state during installation. When the machine head turns, the internal space of the overhead track widens, and the first spring drives the wheel frame to swing, causing the first wheel to open to both sides while still pressing against the internal side walls of the overhead track, further ensuring the smoothness of the machine head's transformation.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1 to 8 As shown, this embodiment provides a steering assist device for a ceiling track machine head, which is installed on the front and rear sides of the machine head 2 inside the ceiling track 1. It includes a mounting frame with a U-shaped plate structure. Specifically, the mounting frame includes a first mounting plate 6, a second mounting plate 7, and a third mounting plate 8. The first mounting plate 6 has a first mounting plate 7 and a third mounting plate 8 fixedly mounted on one side, corresponding to each other. Two wheel frames 3 are hinged to one side of the mounting frame. Wheel frames 3 are hinged between the ends of the second mounting plate 7 and the third mounting plate 8. Multiple first wheels 4 are mounted on the wheel frames 3. When the wheel frames 3 swing, the two wheel frames 3 move closer or further apart, and the first wheels 4 mounted on them move closer or further apart. The multiple first wheels 4 respectively abut against the inner side walls of the ceiling track 1. The wheel frames 3 are positioned such that... A first buffer and a second buffer are respectively provided between the wheel frame 3 and the mounting frame to buffer the movement of the machine head 2 in the direction of travel and on both sides. The first buffer includes a first spring 9, which is fixedly installed between the two wheel frames 3. The elastic force of the first spring 9 ensures the contact and pressure between the first wheel 4 and the inner side walls of the track 1. At the same time, it absorbs the vibration in the direction of the machine head 2 in the direction of travel, ensuring the smooth movement of the machine head. The second buffer includes a second spring 10, which is fixedly installed between the end of each wheel frame 3 near the corresponding first wheel 4 and the first mounting plate 6. The second spring 10 and the first spring 9 cooperate to limit the wheel frame 3 and absorb the vibration of the machine head 2 in the direction of travel, further ensuring the smooth movement of the machine head 2 in the track 1.

[0030] Meanwhile, during installation, the first wheels 4 inside the track 1 are respectively pressed against the two sides inside the track 1. At this time, the first spring 9 is in a compressed state and has not reached the compression limit. When the machine head 2 moves to the turning position of the track 1, since the inner width of the turning position of the track 1 is greater than the width of the straight part, the two wheel frames 3 swing in the opening direction under the action of the first spring 9 (at this time, the second spring 10 is compressed). Under the elastic force of the first spring 9, the first wheels 4 are still pressed against the two sides inside the track 1. Thus, through the cooperation of the first spring 9 and the second spring 10, the machine head 2 is guaranteed to turn smoothly inside the track 1 and the phenomenon of the machine head 2 suddenly moving to both sides is reduced, ensuring the safety of the patient's rehabilitation training.

[0031] Furthermore, when the engine head 2 turns, the first spring 9 and the second spring 10 work together to buffer and absorb the inertia of the engine head movement and the centrifugal force generated by the difference in speed between the two sides, further ensuring that the engine head turns smoothly and avoiding the risks caused by abrupt turning.

[0032] The wheel frame 3 is a U-shaped plate structure. Specifically, the wheel frame 3 includes a vertical plate and two horizontal plates. A second spring 10 is fixedly connected between one side of the vertical plate and the first mounting plate 6. Two horizontal plates corresponding to each other are fixedly installed on the other side. One end of each of the two horizontal plates is hinged to the second mounting plate 7 and the third mounting plate 8, respectively. The other end of each horizontal plate is provided with a first wheel 4. The first wheels 4 installed on the two horizontal plates corresponding to each other are vertically aligned.

[0033] A third buffer is provided above the mounting frame, and a second wheel 5 is provided above the third buffer. The second wheel 5 abuts against the top inner side of the overhead track 1. The third buffer is used to buffer the vertical direction of the machine head 2. The third buffer includes a telescopic rod 11 and a third spring 12 sleeved on the telescopic rod 11. The lower end of the telescopic rod 11 is fixedly connected to the mounting frame, and the upper end is equipped with the second wheel 5. The third spring 12 is disposed between the second wheel 5 and the mounting frame. Figure 3 As shown, the third spring 12 absorbs the vertical vibration during the movement of the machine head 2, effectively enhancing stability.

[0034] Furthermore, the hinged wheel frame 3, along with the first buffer 9, the second buffer 10, and the third buffer, effectively ensures the smoothness of the movement of the machine head 2 during rehabilitation training, thus guaranteeing the safety and stability of the rehabilitation training.

[0035] A fixing component is provided on the side of the mounting frame away from the wheel frame 3 for connecting the mounting frame and the machine head 2. The fixing component includes a fixing plate 13 with a hole in the middle and bolts 14 set on the fixing plate 13. The fixing plate 13 is fixedly connected to the mounting frame, such as... Figure 5As shown, the first mounting plate 6 and the machine head 2 are fixedly connected or disassembled by the bolt 14 and the fixing plate 13. Specifically, the bolt 14 passes through the fixing plate 13 and is fixed to the upper end of the machine head by a nut.

[0036] In use, the overhead rail steering auxiliary device of this utility model is fixedly installed at both ends of the head 2 by fasteners and then installed onto the overhead rail 1.

[0037] Specifically, during the movement of the machine head 2, the first spring 9 is in a compressed state, ensuring that the first wheel 4 is in contact with both sides of the inside of the track 1. When turning (the inside of the track 1 is wider than other positions), the first spring 9 extends and the second spring 10 is compressed under the elastic force of the first spring 9. The first wheel 4 is still in contact with both sides of the inside of the track 1, and buffers the movement of the machine head 2 in all directions during the turning process, ensuring the stability of the machine head 2 during the turning process.

[0038] Furthermore, this invention is also applicable to the buffering of moving mechanisms such as track trolleys in other overhead rail 1 shifting systems during travel and turning, so as to improve their movement stability.

[0039] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
