Description

Technical Field

[0001] This utility model relates to the field of placement rack technology, and in particular to a heavy-duty workpiece placement rack. Background Technology

[0002] Finished workpieces are usually placed together. For large and heavy parts, special racks are needed to arrange them neatly. Existing racks are usually shelf-type shelves with alternating vertical placement. Because the workpieces are heavy, forklifts or hoists are usually needed to move them to each position on the rack. However, using forklifts or hoists requires reserving space for these devices. Otherwise, the forklifts or hoists will not be able to enter and will not be able to lift them. Therefore, traditional racks are inconvenient to use and require a lot of space. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of traditional placement racks in the prior art, which are inconvenient to use and require a large space, and to propose a heavy-duty workpiece placement rack.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A heavy-duty workpiece placement rack includes four rectangular columns, with several vertically spaced support plates fixedly installed between the four columns. Two columns at one end of each support plate are connected to a sliding lifting plate. The columns are equipped with a lifting mechanism that can drive the lifting plate to move up and down. There is a channel between the two columns for the workpiece to pass through. The placement rack also includes a translation component that can translate on the multiple support plates.

[0006] The translation component includes a translation plate with at least four rectangularly distributed rollers mounted on its bottom. The top surface of the support plate has a track along its length, and the rollers are capable of moving on the track.

[0007] The top surface of the translation plate is equipped with second ball bearings arranged in a matrix.

[0008] The translation plate includes a base plate and a movable plate. The rollers are installed at the bottom of the base plate. A first support member is fixed to one end of the base plate. The first support member is rotatably connected to one end of the movable plate via a hinge. The end of the base plate away from the first support member has a lifting component. The lifting component can drive the movable plate to rotate clockwise or counterclockwise around the hinge.

[0009] The lifting assembly includes a second support member fixed to the base plate. A support shaft with its axis arranged along the width direction of the support plate is rotatably connected to the second support member. An eccentrically arranged eccentric rod is fixed to the support shaft. The side of the movable plate away from the roller is supported on the outer circumferential surface of the eccentric rod. An extension rod is installed radially at one end of the support shaft.

[0010] The top surface of the movable plate is equipped with second ball bearings arranged in a matrix.

[0011] The lifting mechanism includes sprockets distributed vertically and rotatably connected to the column, a chain connecting the upper and lower sprockets, a forward and reverse rotating motor driving the sprockets, a vertical slide rail on the outer side of the column, a slider fixed to one side of the lifting plate, the slider being slidably connected to the slide rail and fixed to the outer chain portion of the chain.

[0012] The top surface of the lifting plate is equipped with first ball bearings arranged in a matrix.

[0013] The present invention proposes a heavy workpiece placement rack, which has the following advantages: when placing large and heavy workpieces, the workpiece only needs to be transported to the lifting plate each time, so there is no need to reserve working space for forklifts or hoists on the front and back sides of the placement rack, thus effectively improving the space utilization rate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A heavy workpiece placement rack includes four rectangular columns 1, with several vertically spaced support plates 2 fixedly installed between the four columns 1. Two columns 1 located at one end of the support plates 2 are connected to lifting plates 5 that can slide up and down. The columns 1 are equipped with lifting mechanisms that can drive the lifting plates 5 to move up and down. There is a channel 23 between the two columns 1 for the workpiece 13 to pass through. The placement rack also includes a translation component 7, which can translate on the multiple support plates 2.

[0020] refer to Figure 1 First, the lifting plate 5 is lowered to its lowest position. Then, the workpiece is placed on the lifting plate 5. After that, the position of the lifting plate 5 is adjusted according to the required placement height by the lifting mechanism. After the lifting plate 5 moves to the required position, the workpiece on the lifting plate 5 is pushed onto the translation component 7. The translation component 7 transports the workpiece 13 to the required placement position. Then, the workpiece 13 is pushed down from the translation component 7 to the required placement position. When placing large and heavy workpieces with this device, it is only necessary to transport the workpiece to the lifting plate 5 each time. This eliminates the need to reserve working space for forklifts or hoists on the front and back sides of the placement frame, effectively improving the space utilization rate.

[0021] This device is preferably used on workpieces with a flat bottom surface, such as in a mold manufacturing plant.

[0022] refer to Figure 1 The translation component 7 includes a translation plate 8, at least four rectangularly distributed rollers 9 are installed at the bottom of the translation plate 8, and the top surface of the support plate 2 has a track 3 along its length. The rollers 9 can move on the track 3. For example, stepped tracks can be set on both sides of the support plate 2, so that the rollers 9 are not easy to deviate when they travel on the two tracks 3 respectively. Moreover, this structure is simple, easy to maintain and not easy to be damaged.

[0023] The top surface of the translation plate 8 is equipped with a matrix of second ball bearings 18, and similarly, the top surface of the lifting plate 5 is equipped with a matrix of first ball bearings 6. When the workpiece is placed on the first ball bearings 6 of the lifting plate 5, and the lifting plate 5 moves to the required height, the workpiece is directly pushed. The first ball bearings 6 then smoothly push the workpiece from the lifting plate 5 onto the translation plate 8, and the second ball bearings 18 on the translation plate 8 then smoothly push the workpiece from the translation plate 8 onto the support plate 2, reducing operational difficulty.

[0024] As one implementation method, refer to Figure 3The translation plate 8 includes a base plate 16 and a movable plate 17. Rollers 9 are installed at the bottom of the base plate 16. A first support member 14 is fixedly connected to one end of the base plate 16. The first support member 14 is rotatably connected to one end of the movable plate 17 via a hinge 15. The end of the base plate 16 away from the first support member 14 has a lifting component. The lifting component can drive the movable plate 17 to rotate clockwise or counterclockwise around the hinge 15. The top surface of the movable plate 17 is equipped with second ball bearings 18 arranged in a matrix.

[0025] First, rotate the movable plate 17 to a horizontal position, then push the workpiece on the lifting plate 5 onto the movable plate 17, then move the translation plate 8, and then rotate the movable plate 17 to a slightly downward tilted position so that the workpiece can slide down onto the support plate 2 better along the slope.

[0026] Of course, the first ball 6 and the second ball 18 of this device can also be replaced with evenly distributed rotating rods, with the axis of the rotating rods set along the width direction of the support plate 2.

[0027] The lifting assembly includes a second support member 21 fixed to the base plate 16. A support shaft 20 with its axis arranged along the width direction of the support plate 2 is rotatably connected to the second support member 21. An eccentrically arranged eccentric rod 19 is fixed to the support shaft 20. The side of the movable plate 17 away from the roller 9 is supported on the outer circumference of the eccentric rod 19. An extension rod 22 is installed radially at one end of the support shaft 20. By rotating the extension rod 22, the support shaft 20 drives the eccentric rod 19 to rotate. Because the eccentric rod 19 is eccentrically arranged, the support height of the eccentric rod 19 is different at different positions, thereby realizing the adjustment of the tilt angle of the movable plate 17. The structure is simple, easy to use, and not easily damaged.

[0028] As one embodiment of the lifting mechanism, the lifting mechanism includes sprockets 10 distributed vertically and rotatably connected to the column 1. A chain 11 is connected between the upper and lower sprockets 10. The sprockets 10 are driven by a forward and reverse rotating motor. A vertical slide rail 4 is provided on the outer side of the column 1. A slider 12 is fixedly connected to one side of the lifting plate 5. The slider 12 is slidably connected to the slide rail 4 and fixed to the outer chain portion of the chain 11. The forward and reverse rotating motor drives the sprockets 10 to rotate, causing the chain 11 to move. The movement of the chain 11 drives the slider 12 to move up or down, thereby driving the lifting plate 5 to move up or down.

[0029] As one implementation method, the lifting mechanism can refer to the chain-driven lifting mechanism of a forklift, which uses a hydraulic cylinder to push and pull the lever to move around the sprocket;

[0030] As another implementation method, the lifting mechanism can refer to the ball screw mechanism in the prior art as the lifting power mechanism.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
