[0033] The beneficial effects of the present invention include: 1. Through the track and the moving mechanism, the lifting mechanism can be moved longitudinally on the track. When it moves synchronously with the vehicle body, the supporting mechanism is extended horizontally and located between the plate chain and the vehicle body. The lifting mechanism moves upward to drive the supporting mechanism to abut against the supporting part of the vehicle body, thereby lifting the vehicle body and separating it from the plate chain, realizing the transfer of the vehicle body without stopping the production line, solving the problem that the conventional lifting device is fixed and cannot realize the transfer of the vehicle body without stopping the production line;

[0034] 2. The horizontal telescopic cylinder can drive the supporting sliding member to slide horizontally on the lifting mechanism and extend into the bottom of the vehicle body, so as to achieve lifting and realize the telescopic function of the supporting mechanism. When not lifting, it can be retracted to avoid affecting the transportation line; the support block is arranged on the supporting sliding member and can be used to receive the support block of the vehicle body;

[0035] 3. Two sets of supporting components of the single-side supporting mechanism can form two supporting points for the vehicle body in the longitudinal direction. The two sets of supporting mechanisms can form four supporting points, which can stably support the vehicle body;

[0037] 5. The longitudinal speed of the moving mechanism and the vehicle speed can be detected by the first speed sensor and the second speed sensor. The vehicle body can be detected at a fixed position by the photoelectric trigger and the longitudinal movement of the moving mechanism can be triggered. The first distance, the vehicle speed and the longitudinal speed are calculated by the formula of speed and displacement to facilitate the realization that the supporting part of the vehicle body corresponds to the supporting mechanism in the horizontal direction when the moving mechanism is accelerated to the same speed as the vehicle speed;

[0038] 6. The travel motor can drive the travel wheel to move, thereby driving the mounting frame to move, and realizing the movement of the lifting device. The travel motor is used as the mobile driving mechanism to facilitate the control of the moving speed of the lifting mechanism, so that the supporting part of the vehicle body corresponds to the supporting mechanism in the horizontal direction when the longitudinal moving speed is consistent with the vehicle speed;

[0039] 7. The lifting frame can be driven to move vertically on the mounting frame through the lifting drive device, thereby lifting the vehicle body;

[0040] 8. The structure of the lifting drive mechanism is simple. The lifting motor rotates the retractable transmission belt to realize the lifting and moving of the lifting frame, which is convenient for controlling the lifting and moving of the lifting frame and easy to use.

[0041] 9. The guide mechanism can guide the lifting frame to move up and down on the mounting frame to avoid shaking during movement and improve the stability of the lifting movement;

[0042] 10. The method for lifting a vehicle body on a non-stop transport line provided by the present invention fully utilizes the structural characteristics of the lifting device of the present invention. According to the vehicle speed and the first distance, the longitudinal movement speed of the lifting device is adjusted to be consistent with the vehicle speed and the supporting part of the vehicle body corresponds to the supporting mechanism in the horizontal direction. The supporting mechanism is extended to the supporting part of the vehicle body, and the lifting mechanism rises to lift the vehicle body. This method can transfer the vehicle body without stopping the line, meet the process production requirements, and improve production efficiency.

[0043] The movable lifting device of the present invention can enable the supporting mechanism to move on the track through the moving mechanism. When it moves synchronously with the vehicle body, the supporting mechanism is laterally extended to be located at the bottom of the supporting part of the vehicle body. The lifting mechanism rises and drives the supporting mechanism to move upward to lift the vehicle body, which can realize the transfer of vehicle bodies without stopping the production line and improve production efficiency.

[0059] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] The present invention relates to a movable lifting device 8, which is used for lifting a vehicle body 9 during movement to achieve transfer of the vehicle body 9. Through a track 1 and a moving mechanism, the lifting mechanism can be moved longitudinally on the track 1. When the moving mechanism moves to move synchronously with the vehicle body 9 (the speed is the same and the supporting mechanism 4 corresponds to the supporting part 91 of the vehicle body 9 in the horizontal direction), the supporting mechanism 4 is extended in the horizontal direction and is located between the plate chain and the vehicle body 9. The lifting mechanism 5 moves upward to drive the supporting mechanism 4 to abut against the supporting part 91 of the vehicle body 9, thereby lifting the vehicle body 9 and separating it from the plate chain, achieving transfer of the vehicle body 9 without stopping the line, and solving the problem that the conventional lifting device 8 is fixed and cannot achieve transfer of the vehicle body 9 without stopping the line.

[0061] A movable lifting device 8, specifically, as Figure 1-10 As shown, it includes a track 1, a moving mechanism and a lifting mechanism, wherein the track 1 is located on both sides of the vehicle body 9; the moving mechanism includes a mounting frame 2 that moves on both sides of the track 1 and a moving driving mechanism 3 for driving the mounting frame 2 to move; the lifting mechanism includes a supporting mechanism 4 and a lifting mechanism 5 that is arranged on the mounting frame 2 and can be lifted and moved; the mounting frame 2 and the lifting mechanism 5 both span the bottom of the transportation line 10; the mounting frame 2 is a rectangular three-dimensional frame structure; the supporting mechanism 4 is arranged on both lateral sides of the mounting frame 2 and can be laterally extended and retracted, and is used to support the vehicle body 9 after extension.

[0062] In one embodiment, if Figure 1-3 As shown, the supporting mechanism 4 is described. The supporting mechanism 4 includes a supporting slide 41, a transverse telescopic cylinder 42 and a support block 43. The supporting slide 41 is arranged on the lifting mechanism 5 for transverse sliding. The transverse telescopic cylinder 42 is arranged on the lifting mechanism 5 and the telescopic end is fixedly connected to the supporting slide 41, which is used to drive the supporting slide 41 to slide transversely on the lifting mechanism 5. The support block 43 is fixedly arranged at one end of the supporting slide 41 for abutting against the supporting vehicle body 9. In a specific scheme, a transverse slide 44 is arranged on the lifting mechanism 5, and a transverse slide groove is arranged on the transverse slide 44. The supporting slide 41 is slidably arranged in the transverse slide groove. The supporting slide 41 is used to support the vehicle body 9 after sliding transversely on the lifting mechanism 5. It can be, but not limited to, any one of a plate-shaped, tubular, and rod-shaped structure; for example, a plate-shaped supporting slide 41 is used to support the vehicle body 9 at the supporting portion 91 of the vehicle body 9, which can provide a larger contact area, and a plate-shaped supporting slide 41 can be used on each side of the vehicle body 9 to support the vehicle body 9.

[0063] Based on the support mechanism 4 including a support sliding member 41, as Figure 3-4As shown, in the preferred embodiment, the lifting mechanism 5 is provided with a first limiting structure 56 for limiting the non-lateral movement of the supporting sliding member 41. The first limiting structure 56 includes a first limiting groove 561 and a first limiting protrusion 562 respectively arranged on the lateral slide 44 and the supporting sliding member 41 and coupled to each other. The lateral slide 44 is provided with a first limiting groove 561 on one side or both sides of the slide groove, and the supporting sliding member 41 is provided with a first limiting protrusion 562 corresponding to the first limiting groove 561, so that the supporting sliding member 41 can slide laterally along the lateral slide 44 to prevent movement or rotation in other directions, and at the same time, it can be prevented that after receiving the vehicle body 9, the end of the supporting sliding member 41 close to the vehicle body 9 is subjected to greater pressure, resulting in the separation of the supporting sliding member 41 from the transverse sliding seat; in addition, the first limiting groove 561 and the first limiting protrusion 562 can be arranged in an interchangeable manner, that is, the first limiting groove 561 is arranged on the supporting sliding member 41, and the first limiting protrusion 562 is arranged on the lateral slide 44.

[0064] The supporting mechanism 4 includes a supporting sliding member 41, a transverse telescopic cylinder 42 and a supporting block 43. Figure 1 and Fig. 9 As shown, the supporting mechanism 4 includes two groups of supporting assemblies 40 spaced apart in the longitudinal direction, and each group of supporting assemblies 40 includes the above-mentioned supporting sliding members 41, transverse telescopic cylinders 42 and supporting blocks 43 used in a corresponding manner. The two groups of supporting assemblies 40 of the single-sided supporting mechanism 4 can form two supporting points for supporting the vehicle body 9 in the longitudinal direction, and the two groups of supporting mechanisms 4 can form four supporting points, which can stably support the vehicle body 9. The supporting sliding member 41 of the supporting assembly 40 using this method can be a rod-shaped or tubular structure.

[0065] The supporting mechanism 4 includes two groups of supporting components 40 spaced apart in the longitudinal direction. Figure 5-6 As shown, the lifting device 8 further includes an adjustment component 6, which is arranged on the lifting mechanism 5 and used to adjust the distance between the two groups of supporting components 40; a longitudinal slide 53 is slidably arranged on the lifting mechanism 5; at least one group of supporting components 40 is slidably arranged on the longitudinal slide 53. Through the longitudinal slide 53 slidably arranged on the lifting mechanism 5, the supporting component 40 can be slidably arranged on the longitudinal slide 53, so that the supporting component 40 can slide both horizontally and longitudinally on the lifting mechanism 5; the distance between the two groups of supporting components 40 can be adjusted by the adjustment component 6, so as to correspond to the supporting parts 91 of the vehicle body 9 of different specifications and improve the versatility.

[0066] Based on at least one set of supporting components 40 being arranged on the longitudinal slide seat 53 for transverse sliding, such as Figure 3 , Figure 5-6As shown, the lifting mechanism 5 is fixedly provided with a longitudinal slide rail 54, on which a longitudinal slide seat 53 is slidably provided, and at least one group of supporting slide members 41 of a supporting assembly 40 is slidably provided on the longitudinal slide seat 53; the longitudinal slide seat 53 and the longitudinal slide rail 54 are cooperated with a second limiting structure 55 for preventing the longitudinal slide seat 53 from non-longitudinal movement; the second limiting structure 55 includes a second limiting groove and a second limiting protrusion which are respectively provided on the longitudinal slide seat 53 and the longitudinal slide rail 54 and are coupled to each other. Specifically, a second limiting groove is provided on one or both sides of the longitudinal slide rail 54, and a second limiting protrusion is provided on the longitudinal slide seat 53 corresponding to the second limiting groove, so that the longitudinal slide seat 53 slides longitudinally along the longitudinal slide rail 54 to avoid moving or rotating in other directions, and at the same time, it can be prevented that after receiving the vehicle body 9, the end of the supporting sliding member 41 close to the vehicle body 9 is subjected to greater pressure, resulting in the longitudinal slide seat 53 being separated from the longitudinal slide rail 54; in addition, the second limiting groove and the second limiting protrusion can be arranged interchangeably, that is, the second limiting groove is arranged on the longitudinal slide seat 53, and the second limiting protrusion is arranged on the longitudinal slide rail 54. The first limiting structure 56 can be the same as or different from the second limiting structure 55.

[0067] In a further embodiment, Figure 5-6 As shown, the lifting mechanism 5 is provided with a plurality of longitudinal slide rails 54, which are arranged at intervals on the horizontal line, and the plurality of longitudinal slide rails 54 are provided with a plurality of longitudinal slide seats 53 corresponding thereto, and the plurality of longitudinal slide seats 53 are fixedly provided with the same transverse slide seat 44 (or may be a plurality of transverse slide seats 44 corresponding in the transverse direction), and at least one group of supporting components 40 is transversely slidably arranged on the transverse slide seat 44. The plurality of longitudinal slide seats 53 and the corresponding longitudinal slide rails 54 can support the supporting component 40 at both ends of the transverse direction of the supporting component 40, thereby improving the stability of the supporting component 40 being longitudinally slidably arranged on the lifting mechanism 5. The supporting component 40 is transversely slidably arranged on the transverse slide seat 44, and the same method can be adopted. Preferably, a limit block 57 is fixedly provided on the longitudinal slide rail 54, which is used to limit the longitudinal movement of the longitudinal slide seat 53, so as to prevent the longitudinal slide seat 53 from slipping off the longitudinal slide rail 54 in the longitudinal direction.

[0068] Based on the lifting device 8 also includes an adjustment component 6, such as Figure 5-6 As shown, the adjustment component 6 includes a longitudinal movement motor 61 and a longitudinal rack 62, which are meshed with each other for transmission and are correspondingly arranged on the lifting mechanism 5 and the longitudinal slide 53. The longitudinal movement motor 61 is fixed on the longitudinal slide 53 and the longitudinal rack 62 is fixed on the lifting mechanism 5, or the longitudinal movement motor 61 is fixed on the lifting mechanism 5 and the longitudinal rack 62 is fixed on the longitudinal slide 53. When the longitudinal movement motor 61 rotates, it can drive the longitudinal slide 53 to move longitudinally, thereby adjusting the distance between the two groups of supporting components 40, which is suitable for supporting the supporting parts 91 of vehicle bodies 9 of different specifications.

[0069] In a specific scenario, Figure 6As shown, a mounting plate 511 is fixedly disposed on the lifting mechanism 5 , the adjusting assembly 6 and a group of supporting assemblies 40 are transversely slidably disposed on the mounting plate 511 , and another group of supporting assemblies 40 are transversely slidably disposed on the lifting mechanism 5 .

[0070] In a certain embodiment, the lifting device 8 further includes a first speed sensor, a photoelectric trigger 7, and a second speed sensor. The first speed sensor and the second speed sensor are used to detect the longitudinal speed v1 of the moving mechanism on the track 1 and the speed v2 of the vehicle body 9, respectively; the photoelectric trigger 7 is arranged on the side of the mounting frame 2 close to the vehicle body 9 to be lifted and is separated from the mounting frame 2 by a first distance d1, and is used to trigger the moving mechanism to move on the track 1 by sensing the light when the vehicle body 9 passes by; when the moving mechanism moves to the longitudinal speed v1 and the speed v2 are consistent (within the allowable difference), the supporting part 91 of the vehicle body 9 corresponds to the supporting mechanism 4 in the horizontal direction; after the supporting mechanism 4 is extended to the lower part of the supporting part 91 of the vehicle body 9, the lifting mechanism 5 rises and drives the supporting mechanism 4 to lift the vehicle body 9. The first speed sensor and the second speed sensor can be devices that can detect the longitudinal speed v1 and the speed v2 of the lifting device 8. The first speed sensor can be a speed sensor arranged on the running wheel 21, and the moving speed v1=2nπr is calculated according to the speed n and the radius r of the running wheel 21; the running speed of the conveyor line can be detected as the speed v2.

[0071] In one embodiment, if Figure 1 As shown, a plurality of running wheels 21 rolling against the track 1 are provided on both sides of the mounting frame 2 ; the mobile driving mechanism 3 includes a running motor fixed on the mounting frame 2 and drivingly connected to the running wheels 21 .

[0072] Preferably, if Figure 1 As shown, the travel motor is fixed on the mounting frame 2 and is connected to two second synchronous shafts through a second coupling. The second synchronous shaft is connected to the travel wheel 21 at one end close to the track 1. The travel wheels 21 on both sides of the lateral direction can rotate synchronously through the second synchronous shaft, and the travel wheels 21 not connected to the travel motor serve as driven wheels. The moving speed of the moving mechanism can be controlled by controlling the speed of the travel motor, which is convenient for adjusting the longitudinal speed.

[0073] During specific use, the various actions of the lifting device 8 are regulated by the controller, and the photoelectric trigger 7 detects the position of the vehicle body 9 through light sensing at a fixed position at a preset first distance d1 from the lifting device 8. When the photoelectric trigger 7 senses the front of the vehicle, the controller receives the sensing signal of the photoelectric trigger 7, and regulates the accelerated movement of the moving mechanism until the longitudinal movement speed is consistent with the vehicle speed, and the supporting part 91 of the vehicle body 9 corresponds to the supporting mechanism 4 in the horizontal direction, keeping the speeds of the two synchronized, and regulating the supporting mechanism 4 to extend to below the supporting part 91 of the vehicle body 9. After the lifting mechanism 5 is regulated to move upward to complete the lifting of the vehicle body 9, subsequent production processes are carried out.

[0074] According to the first distance d1 and the vehicle speed v2, the acceleration a of the lifting device 8 (moving mechanism) is regulated, and the velocity and displacement formula can be used to calculate the longitudinal speed and the vehicle speed v2 are consistent and the position of the supporting mechanism 4 corresponding to the supporting part 91 of the vehicle body 9 (the longitudinal distance from the photoelectric trigger 7) and the moving time. There are many calculation methods to achieve the synchronous movement of the supporting device and the vehicle body 9 (the same speed and the supporting mechanism 4 corresponds to the supporting part 91 of the vehicle body 9), which are not limited to the scheme shown in the present invention.

[0075] like Fig.11 As shown, according to the calculation that the vehicle body 9 is fixed on the plate chain of the transport line 10 and runs at a uniform speed, when the supporting part 91 of the vehicle body 9 corresponds to the supporting mechanism 4 in the horizontal direction, the distance between the head of the vehicle body 9 and the head of the lifting device 8 is the fourth distance d4, and the longitudinal length of the lifting device 8 is the fifth distance d5; when the longitudinal moving speed is consistent with the vehicle speed v2, the moving mechanism moves the second distance d2, and the vehicle body 9 moves the third distance d3; when the head of the vehicle body 9 triggers the photoelectric trigger 7, the third distance d3 is equal to the sum of the first distance d1, the second distance d2, the fourth distance d4 and the fifth distance d5, that is, d3=v2t=d1+d2+d4+d5, when the acceleration a is constant, d2=at 2 / 2, we can know that at 2 =2v2t-(d1+d4+d5), since v2 and d1, d4, d5 are all known, the moving time t can be calculated by controlling the acceleration a, and d3 can be calculated, that is, the lifting device 8 is consistent with the vehicle speed v2 and the lifting mechanism corresponds to the supporting part 91 of the vehicle body 9 in the longitudinal direction.
