Description

Technical Field

[0001] The utility model belongs to the technical field of transport tools, and in particular relates to a simplex displacement carrier. Background Art

[0002] Material frames are usually used to place products. After the products are placed in the material frames, they often need to be transferred, which requires a transfer device to transfer the material frames. The existing patent document with patent number CN111824708A discloses a double-layer track transport device, including a rectangular frame, track bars, protrusions, slide blocks, fastening screws and insert plates. The present invention has a double-layer track and can perform three-dimensional double-layer track transportation. The existing disclosed transport device is equipped with a double-layer track, which enables the transport vehicle to transport on two layers of track at the same time. However, the existing transport device can only transport products back and forth in the same axial direction, and cannot move the transport vehicle in multiple axial directions. It has poor versatility and a small transfer range. Therefore, it is necessary to design a simplex displacement carrier to overcome the above difficulties. Summary of the Invention

[0003] In response to the problems existing in the prior art, the utility model designs a simplex displacement carrier. The utility model provides a lower frame on the guide rail that can move axially relative to the lower frame, and provides a plurality of roller assemblies on the upper frame, so that the material frame can be transferred in two axial directions, with good versatility and reliable transportation.

[0004] The invention object of the utility model is achieved through the following technical solutions: a simplex displacement carrier, comprising a lower frame and an upper frame, wherein a pair of guide rails are provided directly below the lower frame; the lower frame is slidably connected to the guide rails, and a first drive assembly is provided between the lower frame and the guide rails; the upper frame is fixedly mounted on the lower frame, and the upper frame is vertically arranged to the guide rails; the upper frame is provided with a plurality of roller assemblies rotatably connected thereto, a first chain for transmission is provided between each of the roller assemblies, a second reduction motor is provided on the upper frame, and a second chain for transmission is provided between the second reduction motor and one of the roller assemblies.

[0005] Preferably, wheel box mounting seats are respectively provided on the four corners of the lower frame, and guide bearings are arranged in pairs on the wheel box mounting seats; a transmission shaft assembly is provided between two of the wheel box mounting seats, and the transmission shaft assembly is connected to the first drive assembly; when the first drive assembly is working, it drives the lower frame to move along the guide track.

[0006] Preferably, the transmission shaft assembly includes transmission shaft bodies arranged in pairs, a coupling connecting the two transmission shaft bodies is provided between the two transmission shaft bodies; a spline shaft is provided at the end of the transmission shaft body, and a universal joint connecting the spline shaft and the transmission shaft body is provided between the two; the end of the spline shaft is provided with a rolling wheel that rotates synchronously with the spline shaft, and the rolling wheel is arranged in a wheel box mounting seat and is rotatably connected to the spline shaft; the rolling wheel and the end face of the guide rail are arranged to fit each other, and a third chain for transmission is provided between the transmission shaft body and the first drive assembly.

[0007] Preferably, the first drive assembly includes a first reduction motor, a first sprocket and a second sprocket; the first reduction motor is fixedly mounted on the side of the lower frame, and a first sprocket is provided on the reducer output shaft of the first reduction motor to rotate synchronously therewith; a second sprocket is provided on the transmission shaft body to rotate synchronously therewith, and a third chain is provided between the first sprocket and the second sprocket; the outer diameter of the first sprocket is smaller than the outer diameter of the second sprocket.

[0008] When the first reduction motor is in operation, it drives the first sprocket to rotate. The first sprocket drives the second sprocket to rotate via the third chain. When the second sprocket rotates, it drives the transmission shaft body to rotate. Here, the outer diameter of the first reduction motor is smaller than that of the second sprocket, which facilitates adjustment of the reduction ratio between the first reduction motor and the transmission shaft body, thereby providing the transmission shaft body with greater torque. The transmission shaft bodies are arranged in pairs, so that the rolling wheels at the ends of the transmission shaft bodies can rotate synchronously, thereby enabling the wheel box mounting seats on both sides to move synchronously, and thus the movement of the lower frame relative to the guide rail is more stable. By providing a universal joint connecting the spline shaft and the transmission shaft body, the rolling wheels can rotate reliably relative to the wheel box mounting seat, preventing the rolling wheels and the wheel box mounting seat from interfering with each other and getting stuck when the lower frame shakes. Because the rolling wheels are arranged in a close fit with the guide rail, the material boxes on the lower frame and the upper frame have a certain weight. Therefore, when the rolling wheels rotate, the lower frame and the upper frame can move as a whole relative to the guide rail.

[0009] Preferably, the guide rail is an I-beam rail, and the guide bearing is rotatably connected to the wheel box mounting seat; the outer wall of the guide bearing and the side of the guide rail are arranged to fit each other, and the guide bearings are symmetrically distributed on the left and right sides of the guide rail.

[0010] The guide bearings are clamped on the left and right sides of the guide rail to prevent the wheel box mounting seat from leaving the guide rail. Then, when the rolling wheel rotates, the lower frame can move reliably relative to the guide rail.

[0011] Preferably, a first buffer is provided on the side of the wheel box mounting base facing the guide rail, the first buffer being arranged parallel to the guide rail. A second buffer is also provided on the side of the lower frame, the second buffer being arranged facing away from the first drive assembly. The first and second buffers provide cushioning protection for the lower frame. This prevents significant shaking of the lower frame when it is moved into position, thereby ensuring stability of the material basket on the upper frame.

[0012] Preferably, the roller assembly includes a pair of vertical mounting seats, each of which is provided with a bearing; a roller body rotatably connected to the two vertical mounting seats is provided between the two vertical mounting seats, and a double-row sprocket that rotates synchronously with the roller body is mounted on the roller body; each of the roller assemblies is arranged parallel to each other, and a first chain is mounted on any two of the roller assemblies, and both ends of the first chain are respectively mounted on the double-row sprockets adjacent to the roller assembly; when the second reduction motor drives the second chain to rotate, each of the roller bodies rotates synchronously.

[0013] Preferably, a third sprocket is provided on the second reduction motor, a fourth sprocket is provided on one of the roller shaft bodies, the fourth sprocket is connected to the roller shaft body via a flat key, and a second chain is provided between the fourth sprocket and the third sprocket.

[0014] Preferably, inner rollers and outer rollers are provided on both sides of the roller body; the inner rollers and outer rollers are connected to the roller body via splines, and the inner rollers and outer rollers rotate synchronously when the roller body rotates.

[0015] When the second reduction motor is operating, the third sprocket rotates synchronously. When the third sprocket rotates, it drives the fourth sprocket to rotate via the second chain. When the fourth sprocket rotates, it drives one of the roller bodies to rotate. The roller body is equipped with a double-row sprocket that rotates synchronously with it. Because the double-row sprockets on each roller body are connected by the first chain, when one roller body rotates, the remaining roller bodies also rotate synchronously. The ends of the roller bodies are equipped with inner and outer rollers, which rotate synchronously when the roller body rotates. The bottom of the material frame rests on the inner roller, and the outer wall of the material frame is clamped on the inner wall of the outer roller, allowing the material frame to move relative to the upper frame. The outer roller limits the material frame, ensuring that it can only move axially along the upper frame, making the movement of the material frame more stable and reliable.

[0016] Compared with the existing technology, the present invention has the following beneficial effects: 1. When the first drive assembly is in operation, it drives the lower frame to move along the guide rail, and when the second reduction motor is in operation, it drives each of the roller assemblies to rotate synchronously, so that the material frame can move relative to the upper frame; because the transfer direction of the roller assembly and the guide rail are arranged perpendicular to each other, the material frame can move arbitrarily in two axial directions, and has good versatility; 2. The lower frame is limited by the guide rail, and a wheel box mounting seat is provided on the lower frame. The rolling wheels in the wheel box mounting seat rotate relative to the guide rail, so that the movement process of the lower frame and the guide rail is more stable. 3. The material frame is driven to move relative to the upper frame by multiple roller assemblies, which has a good transmission effect and high transfer efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0025] like Figures 1 to 6As shown, this embodiment discloses a simplex displacement carrier, including a lower frame 1 and an upper frame 2, and a pair of guide rails 3 are provided directly below the lower frame 1; the lower frame 1 is slidingly connected to the guide rails 3, and a first drive assembly 4 is provided between the lower frame 1 and the guide rails 3; the upper frame 2 is fixedly mounted on the lower frame 1, and the upper frame 2 is vertically arranged to the guide rails 3; the upper frame 2 is provided with a plurality of roller assemblies 5 rotatably connected thereto, and a first chain 6 for transmission is provided between each of the roller assemblies 5, and a second reduction motor 7 is provided on the upper frame 2, and a second chain 8 for transmission is provided between the second reduction motor 7 and one of the roller assemblies 5.

[0026] The four corners of the lower frame 1 are provided with wheel box mounting seats 9, each of which is provided with a pair of guide bearings 10. A transmission shaft assembly 11 is provided between two of the wheel box mounting seats 9, and the transmission shaft assembly 11 is connected to the first drive assembly 4. When the first drive assembly 4 is in operation, it drives the lower frame 1 to move along the guide rail 3. The transmission shaft assembly 11 includes a pair of transmission shaft bodies 111, and a coupling 112 is provided between the two transmission shaft bodies 111 to connect the two. A spline shaft 113 is provided at the end of the transmission shaft body 111, and a universal joint 114 is provided between the spline shaft 113 and the transmission shaft body 111 to connect the two. The end of the spline shaft 113 is provided with a rolling wheel 115 that rotates synchronously with the spline shaft 113. The rolling wheel 115 is provided in the wheel box mounting seat 9 and is rotatably connected thereto. The rolling wheel 115 is arranged to fit the end surface of the guide rail 3. A third chain 12 for transmission is provided between the transmission shaft body 111 and the first drive assembly 4. The first drive assembly 4 includes a first reduction motor 41, a first sprocket 42, and a second sprocket 43. The first reduction motor 41 is fixedly mounted on the side of the lower frame 1. The first reduction motor 41 has a first sprocket 42 mounted on its reducer output shaft, which rotates synchronously therewith. The transmission shaft body 111 has a second sprocket 43 mounted on it, which rotates synchronously therewith. A third chain 12 is disposed between the first sprocket 42 and the second sprocket 43. The outer diameter of the first sprocket 42 is smaller than that of the second sprocket 43. The guide rail 3 is an I-beam rail, and the guide bearing 10 is rotatably connected to the wheel box mounting seat 9. The outer wall of the guide bearing 10 is arranged to fit the side of the guide rail 3, and the guide bearings 10 are symmetrically distributed on the left and right sides of the guide rail 3. A first buffer 13 is disposed on the side of the wheel box mounting seat 9 facing the guide rail 3, and the first buffer 13 is disposed parallel to the guide rail 3. A second buffer 14 is also disposed on the side of the lower frame 1, and the second buffer 14 is disposed away from the first drive assembly 4.

[0027] The roller assembly 5 includes a pair of vertical mounting blocks 51, each equipped with a bearing. A roller body 52 is provided between the two vertical mounting blocks 51, rotatably connected thereto. A double-row sprocket 53 is mounted on the roller body 52, rotating synchronously therewith. Each roller assembly 5 is arranged parallel to each other, and a first chain 6 is mounted on any two roller assemblies 5, with both ends of the first chain 6 mounted on adjacent double-row sprockets 53. When the second reduction motor 7 drives the second chain 8, each roller body 52 rotates synchronously. The second reduction motor 7 is equipped with a third sprocket 15, and one of the roller bodies 52 is equipped with a fourth sprocket 16, which is connected to the roller body 52 via a flat key. A second chain 8 is provided between the fourth sprocket 16 and the third sprocket 15. The roller body 52 is provided with an inner roller 54 and an outer roller 55 on both sides thereof. The inner roller 54 and the outer roller 55 are connected to the roller body 52 via a spline. When the roller body 52 rotates, the inner roller 54 and the outer roller 55 rotate synchronously.

[0028] The specific operation process of this embodiment is as follows: the material frame is placed on the roller assembly 5 of the upper frame 2, and then the material frame can be transferred in two axial directions by operating the first reduction motor 41 and the second reduction motor 7; when the first reduction motor 41 is in operation, it drives the first sprocket 42 to rotate, and the first sprocket 42 drives the second sprocket 43 to rotate through the third chain 12, and when the second sprocket 43 rotates, it drives the transmission shaft body 111 to rotate; here, the outer diameter of the first sprocket 42 is smaller than the outer diameter of the second sprocket 43, which facilitates the adjustment of the reduction ratio of the first reduction motor 41 and the transmission shaft body 111, thereby making the transmission shaft body 111 have a greater torque. The transmission shaft bodies 111 are arranged in pairs, so that the rolling wheels 115 at the ends of the transmission shaft bodies 111 can rotate synchronously, thereby enabling the wheel box mounting seats 9 on both sides to move synchronously, and then the movement process of the lower frame 1 relative to the guide rail 3 is more stable. By providing a universal joint 114 connecting the spline shaft 113 and the transmission shaft body 111, the rolling wheel 115 can reliably rotate relative to the wheel box mounting seat 9, preventing the rolling wheel 115 and the wheel box mounting seat 9 from interfering with each other and getting stuck when the lower frame 1 shakes. Because the rolling wheel 115 is arranged in a close fit with the guide track 3, the material boxes on the lower frame 1 and the upper frame 2 have a certain weight. Therefore, when the rolling wheel 115 rotates, the lower frame 1 and the upper frame 2 can move relative to the guide track 3 as a whole.

[0029] When the second reduction motor 7 is operating, the third sprocket 15 rotates synchronously. The rotation of the third sprocket 15 drives the fourth sprocket 16 via the second chain 8. The rotation of the fourth sprocket 16 drives one of the roller bodies 52 to rotate. Each roller body 52 is equipped with a double-row sprocket 53 that rotates synchronously with it. Because the double-row sprockets 53 on each roller body 52 are connected by the first chain 6, when one roller body 52 rotates, the remaining roller bodies 52 also rotate synchronously. The ends of the roller bodies 52 are equipped with inner rollers 54 and outer rollers 55. When the roller bodies 52 rotate, the inner and outer rollers 54, 55 rotate synchronously. The bottom of the material basket rests on the inner rollers 54, and the outer wall of the material basket is clamped on the inner wall of the outer rollers 55, allowing the material basket to move relative to the upper frame. The outer rollers 55 limit the material basket to move only along the axial direction of the upper frame 2, making the movement of the material basket more stable and reliable.

Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
