Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a parts turnover rack. Background Art

[0002] Cars are an essential means of transportation for everyday commutes. A typical family car is assembled from over 20,000 parts, with complex vehicles often comprising as many as 30,000. In automotive manufacturing, factory-produced auto parts often require short-distance transportation and turnover for subsequent processing and packaging.

[0003] The existing patent publication number is: CN220662571U, which discloses a liftable automobile parts transport rack, including a moving mechanism, a lifting mechanism and a placing plate assembly, the moving mechanism including a movable base; the lifting mechanism includes a lifting frame vertically fixed to the upper end of the movable base, a slide vertically sliding inside the lifting frame, the upper end of the slide is connected to a traction rope, and the traction rope is pulled up and down by a driving device; when it is necessary to transport automobile parts upward, the started traction machine can drive the traction wheel to rotate at a constant speed through the output shaft, and wind up the traction rope, and the traction rope can form vertical traction on the slide under the limiting support of the second fixed pulley and the first fixed pulley, so that the placing plate assembly and the parts on the placing plate will rise synchronously with the slide, and when it is necessary to transport downward, the traction machine drives the traction wheel to rotate in the opposite direction and adjusts the lifting height according to actual needs. Such a design can effectively reduce the labor expenditure of the staff.

[0004] However, in the above-mentioned device, since there is no protective design around the placement plate assembly, after the parts are placed on the placement plate assembly, there is a risk that the parts will slip or fall on the placement plate assembly during the process of lifting or lowering the placement plate assembly or transporting the parts, causing damage to the parts, thereby resulting in economic losses and delays in the operation process. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned deficiencies and provide a parts turnover rack.

The end of the slide away from the screw moves vertically under the guidance of the slide groove, thereby adjusting the height of the parts to facilitate the up and down transportation of parts.

[0034] 2. The utility model sets a protective mechanism. When the parts are adjusting their height, the protective mechanism protects the parts that are in a height change, thereby preventing the parts from falling during the lifting or transportation process; when the second special-shaped plate moves downward and the bottom end of the second special-shaped plate contacts the base, the second special-shaped plate is reversely squeezed by the base, and the second special-shaped plate moves upward, pushing the first special-shaped plate to move horizontally toward the rotating rod, thereby causing the pull rope to drive the rotating rod to rotate. When the rotating rod rotates, it drives the front protective plate to rotate, and the torsion spring and the spring are both in a compressed state. At this time, the placement plate is in an open state, and the placement plate is no longer surrounded by the slide plate, the two side protective plates and the front protective plate, which is convenient for workers to take and place parts from the placement plate.

[0048] Two side panels 21 are provided and are respectively provided on both sides of the placement plate 301;

[0049] The slide plate 303 is provided on the end of the placement plate 301 away from the front protection plate 304;

[0050] The screw rod 23 is rotatably mounted on one of the side plates 21 and passes through the slide plate 303 to be threadedly connected to the slide plate 303;

[0051] The motor 24 is provided at the upper end of the screw rod 23 and is used to drive the screw rod 23 to rotate;

[0052] The slide groove 22 is provided on the side plate 21 and is used for the slide plate 303 to slide.

[0053] In this design, the motor 24 is fixedly mounted on the upper end of the side panel 21, and the output shaft of the motor 24 is fixedly connected to the screw rod 23 through a coupling; when the motor 24 is started, the motor 24 drives the screw rod 23 to rotate, driving the slide plate 303 to move vertically, and the end of the slide plate 303 away from the screw rod 23 moves vertically under the guidance of the slide groove 22.

[0054] In one embodiment, the power assembly includes:

[0055] A rotating rod 308 rotatably mounted on the side guard plate 302 and connected to the front guard plate 304 ;

[0056] The pull rope 307 is wound around both ends of the rotating rod 308 and is used to drive the rotating rod 308 to rotate;

[0057] a torsion spring 309, which is sleeved on both ends of the rotating rod 308 and is used to reset the rotating rod 308;

[0058] The power member is provided on the side protection plate 302 and is used to pull the pull rope 307 .

[0059] With this design, one end of the torsion spring 309 is fixedly connected to the rotating rod 308 , and the other end is fixedly connected to the side protection plate 302 .

[0060] In one embodiment, the power member includes:

[0061] The first special-shaped plate 310 is trapezoidal in shape and has an inclined surface, and is disposed on the end of the pull rope 307 away from the rotating rod 308;

[0065] The guide seat 305 is provided with a through slot 3051 for the second special-shaped plate 311 to slide vertically.

[0066] With this design, the guide seat 305 is fixedly connected to the side protection plate 302 .

[0067] In one embodiment, the reset element comprises:

[0068] A connecting plate 312 is provided at the bottom end of the second special-shaped plate 311;

[0069] A connecting post 313 is provided at the upper end of the connecting plate 312;

[0071] The spring 314 is sleeved on the connecting post 313 , with one end connected to the connecting plate 312 and the other end connected to the notch 315 .

[0072] When the second shaped plate 311 moves downward and the bottom end of the second shaped plate 311 contacts the base 1, the second shaped plate 311 is squeezed in the opposite direction of the base 1, and the second shaped plate 311 moves upward, pushing the first shaped plate 310 to move horizontally toward the rotating rod 308, thereby causing the pull rope 307 to drive the rotating rod 308 to rotate. When the rotating rod 308 rotates, it drives the front guard When the plate 304 rotates, the torsion spring 309 and the spring 314 are both in a compressed state. At this time, the placement plate 301 is in an open state, and the placement plate 301 is no longer surrounded by the slide plate 303, the two side protective plates 302 and the front protective plate 304, which makes it convenient for workers to take and place parts from the placement plate 301; it is worth noting that when the placement plate 301 needs to take and place parts from the aerial platform, the second special-shaped plate 311 is lifted to a height higher than the aerial platform, and then the placement plate 301 is moved to the top of the aerial platform by the roller 11, and then the height of the second special-shaped plate 311 is lowered, thereby facilitating the reverse pressure of the second special-shaped plate 311 by the aerial platform.

[0073] Working principle: When in use, the lifting mechanism adjusts the height of the placement plate 301, thereby adjusting the height of the parts, so as to transport the parts up and down; when the parts are adjusting their height, the protective mechanism protects the parts that are in a height change, preventing the parts from falling during the lifting or transportation process.
