Description

Technical Field

[0001] This utility model relates to the field of lifting and conveying equipment, and in particular to a safety warning type lifting and conveying machine for components. Background Technology

[0002] A lifting conveyor is a machine that vertically and reciprocates to transport components. It typically uses hydraulic rods and connecting rods to vertically raise and lower a platform, transporting parts to a designated location for subsequent production and assembly. Most existing component lifting conveyors lack a structure for positioning the conveying distance, making it difficult to accurately move the platform to the designated position. Furthermore, there is usually a gap between the platform and the unloading point, allowing components to fall through the gap during unloading, increasing the risk to workers below. Manual unloading increases the workload for workers, making it inconvenient to use. Therefore, a safety-prevention type component lifting conveyor is proposed. Utility Model Content

[0003] The present invention addresses the problem that most existing component lifting conveyors do not have a structure for positioning the conveying distance, making it difficult for the carrying platform to move accurately to the designated position. Furthermore, there is usually a certain gap between the carrying platform and the unloading position, which makes it easy for components to fall through the gap during unloading, thereby increasing the danger to the workers below. Manual unloading would increase the labor intensity of the workers, making it inconvenient to use. The present invention provides a safety warning type component lifting conveyor.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A safety warning type component lifting conveyor includes a base, an X-shaped lifting frame, a loading platform, a cavity, two electric rails, an extension component, an unloading component, and a distance sensor;

[0006] The base is horizontally positioned, and the controller is installed on the outer wall of the base.

[0007] The X-shaped lifting frame is installed on top of the base;

[0008] The cargo platform is installed on top of the X-shaped lifting frame;

[0009] The cavity is located at the bottom of the cargo platform;

[0010] Both electric tracks are horizontally arranged and installed inside the cavity;

[0011] The extension assembly is installed on the side of the cargo platform;

[0012] The unloading assembly is installed on top of the cargo platform;

[0013] The distance sensor is mounted on the side of the cargo platform.

[0014] Preferably, the extension assembly includes a telescopic plate, a storage slot, a ramp, a mounting slot, two motorized slide rails, a connecting shaft, and multiple rotating rods;

[0015] The telescopic plate is set horizontally and is located inside the cavity. Both sides of the telescopic plate are fixedly connected to the moving ends of two electric tracks. The moving direction of the telescopic plate is the same as the axial direction of the electric tracks.

[0016] The storage compartment is located at the top of the telescopic panel;

[0017] The inclined plate is set horizontally, and the end of the inclined plate away from the loading platform is rotatably connected to the end of the inner wall of the storage slot away from the loading platform. The rotation axis of the inclined plate is set horizontally and parallel to the axis of the electric track. The length of the inclined plate is less than the length of the telescopic plate.

[0018] The mounting slot is located at the top of the storage compartment;

[0019] Both electric slide rails are horizontally arranged and fixedly connected to the inner wall of the mounting groove.

[0020] The two ends of the connecting shaft are fixedly connected to the sliding ends of the two electric slide rails respectively, and the axis of the connecting shaft is parallel to the rotation axis of the rotating end between the inclined plate and the telescopic plate;

[0021] One end of each of the multiple rotating rods is rotatably connected to the connecting shaft, and their rotation axis coincides with the axis of the connecting shaft. The other end of each of the multiple rotating rods is rotatably connected to the bottom of the inclined plate, and their rotation axis is parallel to the axis of the connecting shaft.

[0022] Using the above technical solution, the moving end of the electric track drives the telescopic plate to move outward, the telescopic plate drives the mounting groove to move outward, and the mounting groove drives the inclined plate, electric slide rail, connecting shaft and multiple rotating rods to move outward until the top of the inclined plate is separated from the cavity. Then, the sliding end of the electric slide rail drives the connecting shaft to move outward, and the connecting shaft drives multiple rotating rods to move outward. The fixing effect between the other end of the rotating rod and the inclined plate causes the rotating rod to rotate upward, thereby lifting the inclined plate through multiple rotating rods, making it easier for parts to slide off the inclined plate, thus realizing the function of automatic unloading.

[0023] Preferably, an elastic plate made of rubber is fixedly connected to one end of the inclined plate near the loading platform.

[0024] Using the above technical solution, the inclined plate is squeezed against the outer wall of the loading platform by the elastic plate during the upward rotation, thereby preventing wear on the inclined plate. At the same time, the inclined plate is kept as close as possible to the loading platform after rotation to prevent parts from falling out of the gap between the inclined plate and the loading platform.

[0025] Preferably, the top of the inclined plate is fixedly connected to two horizontally arranged limiting strips, the axis of which is parallel to the axis of the electric slide rail.

[0026] By adopting the above technical solution, the components are blocked by the limit strip during the downward movement, thereby preventing the components from falling off from both sides.

[0027] Preferably, the unloading assembly includes multiple conveyor rollers, an inclined notch, and a protective frame;

[0028] Multiple conveyor rollers are rotatably connected to the top of the loading platform, and the rotation axis of the conveyor rollers is parallel to the axis of the connecting shaft;

[0029] The inclined notch is located at one end of the loading platform near the inclined plate, and the width of the inclined notch is the same as the width between the two limit strips.

[0030] The protective frame is fixedly connected to the top of the cargo platform. The protective frame has a U-shaped structure and its end near the inclined notch is connected to the outside.

[0031] Using the above technical solution, the motor drives the sprocket to rotate, and the sprocket drives multiple conveyor rollers to rotate through the chain. The multiple conveyor rollers transport the parts to the inclined notch. The inclined notch and the inclined plate tilt the parts to make them fall naturally, thereby automatically unloading the parts and reducing the labor intensity of the workers.

[0032] Preferably, a rubber sleeve is fixedly connected to the outer wall of the conveyor roller, and the outer wall of the rubber sleeve is provided with multiple anti-slip patterns.

[0033] By adopting the above technical solution, the conveyor roller increases the friction between itself and the components through the anti-slip pattern on the outer wall of the rubber sleeve, thereby preventing the components from getting stuck in the loading platform.

[0034] The beneficial effects of this utility model are:

[0035] 1. This utility model automatically unloads parts by placing a telescopic plate on the unloading position and using an inclined plate and a tilted notch, thereby reducing the labor intensity of workers and facilitating the unloading of parts.

[0036] 2. This utility model, through the combined use of inclined plates and elastic plates, prevents parts from falling through the gap between the loading platform and the inclined plates during unloading. At the same time, the combined use of protective frames and limiting strips prevents parts from falling from the side, thereby preventing parts from falling and causing danger to the workers below, thus improving the safety of the equipment.

[0041] As attached Figure 1-2 As shown, this application provides a safety warning type component lifting conveyor, including a base 1, an X-shaped lifting frame 2, a loading platform 3, a cavity, two electric rails, an extension assembly 4, an unloading assembly, and a distance sensor;

[0048] The unloading assembly is installed on top of the loading platform 3;

[0049] The distance sensor is mounted on the side of the loading platform 3.

[0050] The extension component 4 includes a telescopic plate 41, a storage slot, an inclined plate 42, a mounting slot 411, two electric slide rails 412, a connecting shaft 413, and multiple rotating rods 414;

[0051] The telescopic plate 41 is arranged horizontally and is located inside the cavity. The two sides of the telescopic plate 41 are fixedly connected to the moving ends of the two electric tracks respectively. The moving direction of the telescopic plate 41 is the same as the axial direction of the electric tracks.

[0052] The storage slot is located at the top of the telescopic plate 41;

[0053] The inclined plate 42 is set horizontally, and the end of the inclined plate 42 away from the loading platform 3 is rotatably connected to the end of the inner wall of the storage slot away from the loading platform 3. The rotation axis of the inclined plate 42 is set horizontally and parallel to the axis of the electric track. The length of the inclined plate 42 is less than the length of the telescopic plate 41.

[0054] Mounting slot 411 is located at the top of the storage slot;

[0055] Both electric slide rails 412 are arranged horizontally, and both electric slide rails 412 are fixedly connected to the inner wall of the mounting groove 411;

[0056] The two ends of the connecting shaft 413 are fixedly connected to the sliding ends of the two electric slide rails 412 respectively, and the axis of the connecting shaft 413 is parallel to the rotation axis of the rotating end between the inclined plate 42 and the telescopic plate 41.

[0057] One end of each of the multiple rotating rods 414 is rotatably connected to the connecting shaft 413, and their rotation axis coincides with the axis of the connecting shaft 413. The other end of each of the multiple rotating rods 414 is rotatably connected to the bottom of the inclined plate 42, and their rotation axis is parallel to the axis of the connecting shaft 413.

[0058] A rubber elastic plate is fixedly connected to one end of the inclined plate 42 near the loading platform 3.

[0059] Two horizontally arranged limiting strips are fixedly connected to the top of the inclined plate 42, and the axis of the limiting strips is parallel to the axis of the electric slide rail 412.

[0060] The unloading assembly includes multiple conveyor rollers 31, an inclined notch 32, and a protective frame 33;

[0061] Multiple conveyor rollers 31 are rotatably connected to the top of the loading platform 3, and the rotation axis of the conveyor rollers 31 is parallel to the axis of the connecting shaft 413;

[0062] An inclined notch 32 is provided at one end of the loading platform 3 near the inclined plate 42, and the width of the inclined notch 32 is the same as the width between the two limiting strips.

[0063] The protective frame 33 is fixedly connected to the top of the loading platform 3. The protective frame 33 has a U-shaped structure and its end near the inclined notch 32 is connected to the outside.

[0064] A rubber sleeve is fixedly connected to the outer wall of the conveyor roller 31, and the outer wall of the rubber sleeve has multiple anti-slip patterns.

[0065] Working principle: The operator starts the controller, which activates the hydraulic rod. The hydraulic rod drives the X-shaped lifting frame 2 to rise, which in turn drives the loading platform 3 to rise. The loading platform 3 then drives the cavity, two electric rails, distance sensor, multiple conveyor rollers 31, inclined notch 32, protective frame 33, and telescopic plate 41 to rise. The telescopic plate 41 drives the storage slot to rise, which in turn drives the inclined plate 42, mounting slot 411, two electric slide rails 412, connecting shaft 413, and multiple rotating rods 414 to rise until the loading platform 3 reaches the unloading position. At this point, the distance sensor detects the height of the loading platform 3 and transmits the signal to the controller. The controller then shuts off the X-shaped lifting frame 2, thereby raising the loading platform 3 to the accurate position and preventing the loading platform 3 from rising too high, which would make unloading difficult.

[0066] The controller then activates two electric rails. The moving ends of the two electric rails drive the telescopic plate 41 to move outward. The telescopic plate 41 drives the mounting groove 411 to move outward. The mounting groove 411 drives the inclined plate 42, electric slide rail 412, connecting shaft 413, and multiple rotating rods 414 to move outward until the bottom of the telescopic plate 41 rests on the plane of the unloading position. The controller then activates the two electric slide rails 412. The sliding ends of the two electric slide rails 412 drive the connecting shaft 413 to move outward. The connecting shaft 413 drives multiple rotating rods 414 to move outward, thereby lifting the inclined plate 42 through the multiple rotating rods 414, causing the inclined plate... 42 rotates upward around its own axis of rotation. The inclined plate 42 drives the elastic plate to move upward. The elastic plate contacts and bends against the outer wall of the loading platform 3 until the rear end of the inclined plate 42 is flush with the inclined notch 32. Then, the elastic plate returns to its original position under its own elastic force, so that the elastic plate contacts the inclined notch 32, preventing the parts from falling out of the gap between them. Then, the controller starts multiple conveying rollers 31, which convey the parts to the inclined notch 32. The inclined angle between the inclined notch 32 and the inclined plate 42 causes the parts to fall naturally, thereby automatically unloading the parts and reducing the labor intensity of the workers.
