Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 3 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Please see Figure 1-8 This utility model provides a technical solution: a side-mounted machine for multiple vehicle models on the same line, including a frame assembly 1, a lifting assembly 2, a telescopic mechanism 3 and a brake assembly 4;

[0035] There are two support frame assemblies 1, which are arranged opposite each other to support the entire device. Each support frame assembly 1 includes a column 11, a top plate 12, a support plate 13, and a bottom plate 16. There are two columns 11, which are arranged opposite each other. The top plate 12 is fixed to the upper end of the two columns 11, and the bottom of the columns 11 is fixedly connected to the bottom plate 16 through the support plate 13. The bottom plate 16 is connected between the four support frame assemblies 1.

[0036] A slide rail 14 is provided on one side of the column 11, and a slider 15 is slidably connected to the outer side of the slide rail 14. The slider 15 is connected to the lifting frame mechanism 22.

[0037] The lifting assembly 2 is installed on the upright assembly 1 and includes a drive mechanism 21 and a lifting frame mechanism 22. The drive mechanism 21 is installed on the upper end of the upright assembly 1. There are two lifting frame mechanisms 22, which are symmetrically installed on the drive mechanism 21. Each upright assembly 1 has two lifting frame mechanisms 22, and there are four lifting frame mechanisms 22 on the two upright assemblies 1. The four lifting frame mechanisms 22 form a quadrilateral to support the vehicle body.

[0038] The drive mechanism 21 includes a drive motor 211, a drive shaft 212, a roller sprocket 214, and a chain 216.

[0039] The drive motor 211 is installed on the outside of the top plate 12, and the drive shaft 212 is located below the top plate 12. The drive shaft 212 is installed at the lower end of the top plate 12 through the bearing seat 213. One end of the drive shaft 212 is connected to the output end of the drive motor 211. There are two roller sprockets 214, which are symmetrically installed on the outer side of the drive shaft 212. A chain 216 is sleeved on the outer side of the roller sprockets 214. The chain 216 is connected to the lifting frame mechanism 22. The drive motor 211 drives the drive shaft 212 to rotate, and then the lifting frame mechanism 22 moves up and down under the action of the roller sprockets 214 and the chain 216, thereby adjusting the height position.

[0040] In this embodiment, an intermediate sprocket 217 is provided on the side of the base plate 16 near each column 11. The roller sprockets 214 on the two upright assemblies 1 on the same side share a chain 216. The chain 216 is sequentially sleeved on the outside of the intermediate sprocket 217, which can ensure that the chain 216 is always in a taut state and ensure the stability of lifting.

[0041] The lifting frame mechanism 22 includes a bracket 221, a support plate 222, a vertical rod 223, a horizontal rod 224, a connecting plate 225, and an induction switch plate 229.

[0042] One end of the bracket 221 is equipped with a support plate 222, on which a telescopic cylinder 31 is mounted. The other end of the bracket 221 is connected to a vertical rod 223. A horizontal rod 224 is fixed to one side of the upper end of the vertical rod 223. A chain 216 passes through the horizontal rod 224. A sensor switch plate 229 is installed on one side of the horizontal rod 224. A connecting plate 225 is fixed to one end of the horizontal rod 224. A lifting switch group is correspondingly provided on one side of the sensor switch plate 229. The height position of the vehicle body can be reflected in real time through the sensing cooperation between the sensor switch plate 229 and the lifting switch group.

[0043] The telescopic mechanism 3 includes a telescopic cylinder 31, a slide 32, a telescopic plate 33, and a support block 34. The slide 32 is mounted on the support plate 222 and has an opening at one end. The telescopic plate 33 is slidably connected inside the slide 32. The telescopic end of the telescopic cylinder 31 is connected to the telescopic plate 33. The support block 34 is fixed on the upper surface of the telescopic plate 33 and is used to support the vehicle body. The telescopic cylinder 31 controls the extension position of the telescopic plate 33, thereby controlling the horizontal position of the support block 34 supporting the vehicle body. The horizontal telescopic position can be adjusted according to different vehicle models.

[0044] The brake assembly 4 includes a base 41, a brake cylinder 42, a pin 43, and a fixing plate 44. The base 41 is installed on one side of the top plate 12, the brake cylinder 42 is installed on the base 41, the telescopic end of the brake cylinder 42 is connected to the pin 43, the fixing plate 44 is installed on the door lock shaft of the base 41, and the pin 43 passes through the fixing plate 44.

[0045] A brake wheel 215 is mounted on the outer side of the drive shaft 212. The brake wheel 215 has evenly distributed insertion holes. The brake cylinder 42 drives the pin 43 to extend into the insertion holes on the brake wheel 215. When the vehicle height is raised or lowered to the correct position, the brake cylinder 42 drives the pin 43 to extend into the insertion holes on the brake wheel 215 to prevent 212 from rotating, thus achieving mechanical self-locking. No manual operation is required, which prevents the lifting assembly 2 and the telescopic mechanism 3 from falling accidentally, greatly improving operational safety.

[0046] To ensure that the lifting direction of the lifting frame mechanism 22 is always vertical, a slide rail 14 is provided on one side of the column 11, and a slider 15 is slidably connected to the outer side of the slide rail 14. The slider 15 is fixedly connected to the connecting plate 225.

[0047] To facilitate the maintenance or replacement of parts of the drive mechanism 21, the upper end of the top plate 12 is provided with multiple openable maintenance doors 17.

[0048] In order to balance the load, reduce the driving force of the drive motor 211, and make the lifting of the cloud top more stable, the free end of the chain 216 is equipped with a counterweight 218 that matches the weight of the lifting frame mechanism 22 and the telescopic mechanism 3.

[0049] To provide timely alarm in case of chain breakage 216, a pull rod 226 is perpendicularly inserted through the surface of the crossbar 224. The upper and lower ends of the pull rod 226 are fixedly connected to the chain 216. A pressure block 230 is provided at the lower end of the outer side of the pull rod 226. A compression spring 227 is provided between the pressure block 230 and the lower surface of the crossbar 224. The compression spring 227 is sleeved on the outer side of the pull rod 226. A belt breakage detection plate 228 is provided below the pressure block 230. The pull rod 226 passes through the belt breakage detection plate 228. Under normal conditions, the chain 216 pulls the pull rod 226, causing the compression spring 227 to be in a compressed state. When the chain 216 breaks, the compression spring 227 releases its elasticity under the action of gravity, and the pressure block 230 contacts the belt breakage detection plate 228. The belt breakage detection plate 228 is connected to the output end of the control system, and the control system controls the brake assembly 4 to brake immediately to prevent the vehicle from falling.

[0050] In use: After the control system receives information about the upcoming vehicle model on the production line, it automatically retrieves the corresponding support height H and horizontal extension amount L. The drive motor 211 in the lifting assembly 2 starts and drives the lifting frame mechanism 22 to rise and fall through the chain 216. The support height H is accurately positioned through the induction switch plate 229 and the corresponding lifting switch group. Then the brake cylinder 42 is activated, and the control pin 43 is inserted into the hole of the brake wheel 215 to complete the locking.

[0051] Next, the telescopic cylinder 31 in the telescopic mechanism 3 pushes the telescopic plate 33 to move horizontally within the slide block 32 until it reaches the preset horizontal position L, thereby accurately supporting the body of the vehicle.

[0052] When maintenance is required, the maintenance personnel first lock the entire device through the brake assembly 4, and then open the inspection door 17 for maintenance. The whole process is safe and labor-saving.

[0053] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model.
