Description

Technical Field

[0001] The utility model relates to a lifting mechanism, in particular to a lifting mechanism of an X-ray machine system. Background Art

[0002] In an X-ray machine system, in order to cope with different radiography positions, it is often necessary to adjust the height of a radiography assembly composed of a flat panel detector and an X-ray tube assembly to adjust the radiography height. Currently, the X-ray machine system connects the radiography assembly to a lifting mechanism and adjusts the height of the radiography assembly through the lifting mechanism.

[0003] There are mainly three types of existing lifting mechanisms for X-ray machine systems: a manual lifting mechanism, an electric lifting mechanism, and a manual-electric integrated lifting mechanism. Among them, the manual lifting mechanism can only be manually operated by staff to adjust the radiography height, the electric lifting mechanism automatically adjusts the radiography height by controlling an electric drive component (such as a cylinder or a motor, etc.) therein, and the manual-electric integrated lifting mechanism can adjust the radiography height manually or automatically by operating a manual-electric integrated drive component therein.

[0004] Due to different operation forms, the costs of these three types of lifting mechanisms vary greatly. Different hospitals have different requirements for the operation forms of the lifting mechanism due to budget and doctors' operation habits. In order to meet the different needs of various customers in the market, manufacturers often need to stock three major categories of products, namely, manual lifting mechanisms, electric lifting mechanisms, and manual-electric integrated lifting mechanisms, respectively, and the stocking pressure is relatively high. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a lifting mechanism of an X-ray machine system that can selectively achieve any one of the manual lifting function, the electric lifting function, and the manual-electric integrated lifting function alone, meet the needs of different customers for cost and operation form, and reduce the stocking pressure of manufacturers.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is as follows: A lifting mechanism of an X-ray machine system includes a transmission assembly, two transmission chains, a manual-automatic integrated drive assembly, and an electric drive assembly. The two transmission chains are installed on the transmission assembly. One end of the two transmission chains is used to install the radiographing assembly, and the other end is used to install the counterweight. The transmission assembly can be manually operated to drive the two transmission chains to adjust the heights of both ends of the two transmission chains. The electric drive assembly can be connected to the transmission assembly. When the electric drive assembly is connected to the transmission assembly, the transmission assembly is used to drive the two transmission chains under the drive of the electric drive assembly. The manual-automatic integrated drive assembly can be connected to the transmission assembly. When the manual-automatic integrated drive assembly is connected to the transmission assembly, the transmission assembly can be driven by the manual-automatic integrated drive assembly to drive the two transmission chains, and can also be manually operated to drive the two transmission chains.

[0007] The transmission assembly includes a transmission wheel mechanism and a braking mechanism. The transmission wheel mechanism includes a mounting plate, two bearing seats, a transmission shaft, a driving sprocket, a driven sprocket, and a cylindrical gear. The two bearing seats are arranged at intervals left and right and are respectively fixed on the mounting plate. The transmission shaft is installed on the two bearing seats and can rotate relative to the two bearing seats under force. The driving sprocket, the cylindrical gear, and the driven sprocket are coaxially fixed on the transmission shaft in sequence from left to right. The two transmission chains are respectively installed on the driving sprocket and the driven sprocket in a one-to-one correspondence. The braking mechanism includes a braking fixed plate and a brake. The brake is fixedly installed on the braking fixed plate. The braking fixed plate is fixedly installed on the mounting plate. The brake is connected to the right end of the transmission shaft and is used to brake the transmission shaft.

[0008] The transmission assembly further includes a position reading mechanism. The position reading mechanism includes a potentiometer and a potentiometer mounting bracket. The potentiometer is fixed on the potentiometer mounting bracket. The potentiometer mounting bracket is fixedly installed on the mounting plate. The potentiometer is connected to the left end of the transmission shaft and is used to read the position data of the transmission shaft.

[0009] The described manual-automatic integrated drive assembly includes a first motor mounting bracket, a first motor, a normally-closed clutch, and a first drive gear for meshing with the cylindrical gear. The first motor is mounted on the first motor mounting bracket. The first drive gear is coaxially arranged on the output shaft of the first motor. One of the stator and armature of the normally-closed clutch is mounted on the output shaft of the first motor, and the other is mounted on the first drive gear. When the normally-closed clutch is de-energized, the stator and armature of the normally-closed clutch are attracted to each other. At this time, the first drive gear is relatively fixed to the output shaft of the first motor. When the normally-closed clutch is energized, the stator and armature of the normally-closed clutch are disengaged. At this time, the first drive gear can rotate around the output shaft of the first motor under force.

[0010] The first motor is a worm and worm gear motor.

[0011] The described electric drive assembly includes a second motor mounting bracket, a second motor, and a second drive gear for meshing with the cylindrical gear. The second motor is mounted on the second motor mounting bracket. The second drive gear is fixedly mounted on the output shaft of the second motor.

[0012] The second motor is a worm and worm gear motor.

[0013] Compared with the prior art, the advantages of the present utility model are that the lifting mechanism of the X-ray machine system is composed of a transmission assembly, two transmission chains, a manual-automatic integrated drive assembly, and an electric drive assembly. The two transmission chains are mounted on the transmission assembly. One end of the two transmission chains is used to mount the radiographing assembly, and the other end is used to mount the counterweight. The transmission assembly can be manually operated to drive the two transmission chains to adjust the heights of both ends of the two transmission chains. The electric drive assembly can be connected to the transmission assembly. When the electric drive assembly is connected to the transmission assembly, the transmission assembly is used to drive the two transmission chains under the drive of the electric drive assembly. The manual-automatic integrated drive assembly can be connected to the transmission assembly. When the manual-automatic integrated drive assembly is connected to the transmission assembly, the transmission assembly can be driven by the manual-automatic integrated drive assembly to drive the two transmission chains, and can also be manually operated to drive the two transmission chains. In the present utility model, the manual-automatic integrated drive assembly and the electric drive assembly are optional accessories. In actual use, customers can determine whether to select the manual-automatic integrated drive assembly or the electric drive assembly according to their own requirements for cost and operation mode, so as to be able to choose to individually implement any one of the manual lifting function, the electric lifting function, and the manual-automatic integrated lifting function. Thus, the manufacturer only needs to stock one kind of lifting mechanism of the X-ray machine system of the present utility model to meet the requirements of different customers for cost and operation mode, greatly reducing the stocking pressure of the manufacturer.

[0028] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Embodiment 1: As shown in Figures 1 to 3 , a lifting mechanism of an X-ray machine system includes a transmission assembly 1, two transmission chains 2, a manual-automatic integrated drive assembly 3, and an electric drive assembly 4. The two transmission chains 2 are installed on the transmission assembly 1. One end of each of the two transmission chains 2 is used to install an imaging assembly, and the other end is used to install a counterweight. The transmission assembly 1 can be manually operated to drive the two transmission chains 2 to adjust the heights of both ends of the two transmission chains 2. The electric drive assembly 4 can be connected to the transmission assembly 1. When the electric drive assembly 4 is connected to the transmission assembly 1, the transmission assembly 1 is used to drive the two transmission chains 2 under the drive of the electric drive assembly 4. The manual-automatic integrated drive assembly 3 can be connected to the transmission assembly 1. When the manual-automatic integrated drive assembly 3 is connected to the transmission assembly 1, the transmission assembly 1 can be driven by the manual-automatic integrated drive assembly 3 to drive the two transmission chains 2, and can also be manually operated to drive the two transmission chains 2.

[0030] In this embodiment, the transmission assembly 1 and the two transmission chains 2 are mandatory accessories, and the manual-automatic integrated drive assembly 3 and the electric drive assembly 4 are optional accessories. In actual use, customers can determine whether to select the manual-automatic integrated drive assembly 3 or the electric drive assembly 4 according to their own requirements for cost and operation mode. When the customer needs a lifting mechanism with a manual lifting function, neither the manual-automatic integrated drive assembly 3 nor the electric drive assembly 4 is required. When the customer needs a lifting mechanism with an electric lifting function, the customer only needs to additionally select the electric drive assembly 4. When the customer needs a lifting mechanism with a manual-automatic integrated lifting function, the customer only needs to additionally select the manual-automatic integrated drive assembly 3. Thus, the manufacturer only needs to stock a lifting mechanism of an X-ray machine system of the present utility model to meet the requirements of different customers for cost and operation mode, greatly reducing the stocking pressure on the manufacturer.

[0031] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that: in this embodiment, as shown in Figures 4 to 7 , the transmission assembly 1 includes a transmission wheel mechanism and a braking mechanism. The transmission wheel mechanism includes a mounting plate 5, two bearing seats 10, a transmission shaft 6, a driving sprocket 7, a driven sprocket 8, and a cylindrical gear 9. The two bearing seats 10 are arranged at intervals left and right and are respectively fixed on the mounting plate 5. The transmission shaft 6 is installed on the two bearing seats 10 and can rotate relative to the two bearing seats 10 under force. The driving sprocket 7, the cylindrical gear 9, and the driven sprocket 8 are coaxially fixed on the transmission shaft 6 in sequence from left to right. The two transmission chains 2 are respectively installed on the driving sprocket 7 and the driven sprocket 8; the braking mechanism includes a braking fixing plate 11 and a brake 12. The brake 12 is fixedly installed on the braking fixing plate 11. The braking fixing plate 11 is fixedly installed on the mounting plate 5. The brake 12 is connected to the right end of the transmission shaft 6 and is used to brake the transmission shaft 6.

[0032] In this embodiment, as Figure 8 shown, the transmission assembly 1 further includes a position reading mechanism. The position reading mechanism includes a potentiometer 13 and a potentiometer mounting bracket 14. The potentiometer 13 is fixed on the potentiometer mounting bracket 14, and the potentiometer mounting bracket 14 is fixedly installed on the mounting plate 5. The potentiometer 13 is connected to the left end of the transmission shaft 6 for reading the position data of the transmission shaft 6.

[0033] In this embodiment, when implementing the manual lifting function, the brake 12 is released from braking the transmission shaft 6, and the cylindrical gear 9 is manually rotated, which can synchronously drive the transmission shaft 6, the driving sprocket 7, and the driven sprocket 8 to rotate synchronously, thereby changing the heights of both ends of the two transmission chains 2 and realizing the manual adjustment of the height of the radiographing assembly. After the height of the radiographing assembly is adjusted in place, the brake 12 brakes the transmission shaft 6 again. The position reading mechanism can display the rotation position of the transmission shaft 6 in real time, so as to facilitate the operator to intuitively obtain the position information.

[0034] Embodiment 3: This embodiment is basically the same as Embodiment 2, except that: In this embodiment, as Figures 9(a) to 11 shown, the manual-automatic integrated drive assembly 3 includes a first motor mounting bracket 15, a first motor 16, a normally closed clutch, and a first drive gear 17 for meshing with the cylindrical gear 9. The first motor 16 is installed on the first motor mounting bracket 15. The first drive gear 17 is coaxially arranged on the output shaft of the first motor 16. One of the stator 18 and the armature 19 of the normally closed clutch is installed on the output shaft of the first motor 16, and the other is installed on the first drive gear 17. When the normally closed clutch is powered off, the stator 18 and the armature 19 of the normally closed clutch are attracted, and at this time, the first drive gear 17 is relatively fixed to the output shaft of the first motor 16. When the normally closed clutch is powered on, the stator 18 and the armature 19 of the normally closed clutch are disconnected, and at this time, the first drive gear 17 can rotate around the output shaft of the first motor 16 under force.

[0035] The first motor 16 in this embodiment is a worm and worm gear motor.

[0036] In this embodiment, when it is necessary to implement the manual-automatic integrated lifting function and select the manual-automatic integrated drive assembly 3, the first motor mounting bracket 15 will be installed on the mounting plate 5, and the first drive gear 17 meshes with the cylindrical gear 9. When adjusting the height electrically, the brake 12 releases the braking on the transmission shaft 6, and the normally closed clutch is powered off. The stator 18 and the armature 19 of the normally closed clutch are attracted to each other, and the first drive gear 17 is relatively fixed to the output shaft of the first motor 16. The first motor 16 drives the first drive gear 17 to rotate, and the first drive gear 17 drives the cylindrical gear 9, the driving sprocket 7, the driven sprocket 8, and the transmission shaft 6 to rotate synchronously, thereby changing the heights of both ends of the two transmission chains 2 and realizing the electric adjustment of the height of the radiographing assembly. After the height of the radiographing assembly is adjusted in place, the brake 12 brakes the transmission shaft 6 again. When adjusting manually, the brake 12 releases the braking on the transmission shaft 6, and the normally closed clutch is powered on. The stator 18 and the armature 19 of the normally closed clutch are disengaged, and the cylindrical gear 9 is rotated manually, which can drive the transmission shaft 6, the driving sprocket 7, the driven sprocket 8, and the first drive gear 17 to rotate synchronously, thereby changing the heights of both ends of the two transmission chains 2 and realizing the manual adjustment of the height of the radiographing assembly. After the height of the radiographing assembly is adjusted in place, the brake 12 brakes the transmission shaft 6 again.

[0037] Embodiment 4: This embodiment is basically the same as Embodiment 2, the difference being that: in this embodiment, as Figure 12 and Figure 13 shown, the electric drive assembly 4 includes a second motor mounting bracket 20, a second motor 21, and a second drive gear 22 for meshing with the cylindrical gear 9. The second motor 21 is installed on the second motor mounting bracket 20, and the second drive gear 22 is fixedly installed on the output shaft of the second motor 21.

[0038] In this embodiment, the second motor 21 is a worm and worm gear motor.

[0039] In this embodiment, when it is necessary to implement the electric lifting function and select the electric drive assembly 4, the second motor mounting bracket 20 will be installed on the mounting plate 5, and the second drive gear 22 meshes with the cylindrical gear 9. When adjusting the height, the brake 12 releases the braking on the transmission shaft 6, and the second motor 21 drives the second drive gear 22 to rotate. The second drive gear 22 drives the cylindrical gear 9, the driving sprocket 7, the driven sprocket 8, and the transmission shaft 6 to rotate synchronously, thereby changing the heights of both ends of the two transmission chains 2 and realizing the electric adjustment of the height of the radiographing assembly. After the height of the radiographing assembly is adjusted in place, the brake 12 brakes the transmission shaft 6 again.
