Description

Technical Field

[0001] This utility model belongs to the field of glass transportation and relates to a protective device for glass transportation. Background Technology

[0002] Glass transportation is a highly specialized and meticulous logistics activity, mainly involving the safe and efficient transfer of glass products such as flat glass, automotive glass, architectural glass, and art glass from the place of production to the place of use.

[0003] For example, the glass transport protective device and glass transport protective frame disclosed in CN222780450U includes a mobile vehicle body. Linear guide rails are installed on the top outer wall of the mobile vehicle body. The linear guide rails are connected to support vertical plates via sliders. An electric push rod is installed on one side wall of the support vertical plate. The output end of the electric push rod is connected to a pull rod. Fixed side plates are installed on the side wall of the pull rod. Fixed vertical plates are installed on one side wall of the fixed side plate. By placing the glass on the fixed support plate, the pull rod can drive the upper pressure plate to descend and press the glass, thereby fixing the glass stably. When disassembling the glass, the electric push rod drives the pull rod to rise, so that the upper pressure plate no longer presses on the glass. At the same time, the support column on the lower top plate can protrude from the fixed support plate and lift the glass. The bottom surface of the glass is supported by the support ball at one end of the fixed support plate, so that the worker can pull the glass more easily, thereby making it easier and faster to unload the glass.

[0004] While the above-mentioned technical solution allows workers to pull the glass more easily and unload it more conveniently and quickly, the equipment relies solely on compression to limit the glass during transport and protection. Furthermore, the presence of ball bearings at the glass placement point means that if the equipment tilts, the glass may slip out of the equipment and break due to the lack of protective devices on the sides. Summary of the Invention

[0005] The technical problem this invention aims to solve is that while the aforementioned technical solutions allow workers to pull the glass more easily and unload it more quickly, the equipment relies solely on compression to limit the glass during transport. Furthermore, the presence of ball bearings at the glass placement point makes it susceptible to glass slippage and breakage when the equipment tilts due to the lack of side protection. This invention overcomes the shortcomings of the prior art by providing a protective device for glass transport.

[0006] The present invention discloses a protective device for glass transportation, comprising a fixed base plate, a drive motor at one end of the other side of the fixed base plate, and L-shaped protective rods on the other side of the upper two sides of the fixed base plate. The output shaft of the drive motor passes through the fixed base plate, and a bidirectional lead screw A is fixedly connected to the output shaft of the drive motor. A synchronous pulley A is fixedly connected to the middle of the bidirectional lead screw A, and a synchronous belt is sleeved on the surface of the synchronous pulley A. A synchronous pulley B is drivenly connected to one end of the inner cavity of the synchronous belt, and a bidirectional lead screw B is fixedly connected to the inner cavity of the synchronous pulley B. A protective mechanism is provided on one side of the bidirectional lead screw B.

[0007] The other side of the bidirectional lead screw B passes through the fixed base plate. One side of the bidirectional lead screw B is movably connected to the inner cavity of the fixed base plate through a rotating joint. The two L-shaped protective rods are threadedly connected to both sides of the bidirectional lead screw A. A telescopic frame A is provided between the opposite sides of the two L-shaped protective rods. Clamping columns are threadedly connected to both sides of the surface of the bidirectional lead screw B. The opposite sides of the two clamping columns are connected through the telescopic frame B.

[0008] The protective mechanism includes a transmission assembly, which is meshed with the other side of the bidirectional lead screw B. A bevel gear is meshed with one side of the upper end of the transmission assembly, and a drive shaft is fixedly connected to one side of the bevel gear. A rotating shaft is slidably connected to one side of the surface of the drive shaft through a limiting strip A.

[0009] The surface of the rotating shaft is slidably connected to a drive spline via a limiting strip B. A push rod is provided at the lower part of the other side of the drive spline. The push rod is in movable contact with the drive spline and can be used to push the drive spline. An electric cylinder A is provided at the lower part of the other side of the push rod. The output shaft of the electric cylinder A is fixedly connected to the push rod. The lower part of the electric cylinder A is fixedly connected to the upper part of the telescopic frame.

[0010] A spur gear is provided on one side of the rotating shaft surface. A spline groove is opened in the inner cavity of the spur gear, and the spline groove cooperates with the drive spline. A limit groove is opened on the other side of the spur gear. A roller is movably connected to the inner cavity of the limit groove. A support rod is movably connected to the other side of the roller. A positioning plate is fixedly connected to the surface of the support rod. The positioning plate is fixedly connected to the upper part of the telescopic frame B.

[0011] An electric cylinder B is fixedly connected to the upper part of the telescopic frame B on one side of the spur gear. A fixing plate is fixedly connected to the output shaft of the electric cylinder. A push rod B is fixedly connected to the upper part of the other side of the fixing plate. A fixing rod is provided on the other side of the fixing plate at the lower part of the push rod B. A fixing groove is opened on one side of the spur gear. The fixing rod and the fixing groove cooperate with each other.

[0012] One end of the spur gear is meshed with a rack, and one end of the rack is fixedly connected to a hollow protective frame. A sliding protective frame is slidably connected to one side of the inner cavity of the hollow protective frame. Positioning grooves are respectively opened in the inner cavities of the sliding protective frame and the hollow protective frame. Guide rods are fixedly connected to opposite sides of the two clamping columns. The positioning grooves and guide rods on the sliding protective frame and the hollow protective frame are slidably connected.

[0013] Working process or working principle:

[0014] When glass protection is required during transport, the drive motor is started. The output shaft of the drive motor drives the double-sided lead screw A to rotate. When the double-sided lead screw A rotates, it drives the synchronous pulley A to move. The synchronous pulley A then drives the synchronous drive pulley B to rotate synchronously. The synchronous pulley B then drives the double-sided lead screw B to rotate. The rotation of the double-sided lead screw A synchronously drives the two L-shaped protective bars to move. The double-sided lead screw B then drives the two clamping columns to move relative to each other, adjusting them to the appropriate position for placing the glass. After adjustment, the glass is placed onto the equipment by the operator. When the positions of the clamping columns and L-shaped protective bars need to be adjusted, the double-sided lead screw B drives the transmission assembly to move. The transmission assembly drives the bevel gear to rotate. Then, the electric cylinder A is started. The output shaft of the electric cylinder A drives the push rod to move. The push rod drives the drive spline to move, moving the drive spline into the interior of the flat gear, so that the flat gear engages with the drive spline. After engagement, the electric cylinder A resets, and the bevel gear drives the drive spline to rotate. The rotating shaft drives the limit bar A to rotate the rotating shaft, which in turn drives the limit bar B to rotate the drive spline. The drive spline then drives the spur gear to rotate, which in turn drives the rack to move the hollow protective frame upwards. The movement of the hollow protective frame then drives the sliding anti-slip frame. After the positions of the clamping column and the L-shaped protective rod are adjusted, the rack stops moving. At this point, the hollow protective frame is positioned at the top of the equipment. The electric cylinder B is then activated, and its output shaft drives the fixed plate to move. The fixed plate then drives the push rod and the fixed rod to move. The push rod pushes the drive spline to the outside of the spur gear's inner cavity. The fixed rod then limits the spur gear. After the glass is placed, the electric cylinder B is activated again to reset its output shaft. Since the spur gear and rack do not have a self-locking mechanism, the hollow protective frame and the sliding protective frame automatically reset to protect the side of the glass, preventing it from slipping out of the equipment due to tilting.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by using the bevel gear, flat gear and rack transmission of the protective mechanism, the hollow protective frame and sliding protective frame are automatically raised and lowered, forming side protection after the glass is placed, effectively preventing the glass from slipping due to the tilt of the equipment.

[0024] Example 1

[0025] like Figures 1-4 As shown, the device includes a fixed base plate 1, a drive motor 2 is installed at the other end of the other side of the fixed base plate 1, and L-shaped protective rods 3 are respectively installed on the other side of the upper part of the fixed base plate 1. The output shaft of the drive motor 2 passes through the fixed base plate 1, and a bidirectional lead screw A4 is fixedly connected to the output shaft of the drive motor 2. A synchronous pulley A5 is fixedly connected to the middle of the bidirectional lead screw A4. A synchronous belt 7 is sleeved on the surface of the synchronous pulley A5. A synchronous pulley B8 is drivenly connected to one end of the inner cavity of the synchronous belt 7. A bidirectional lead screw B9 is fixedly connected to the inner cavity of the synchronous pulley B8. A protective mechanism is installed on one side of the bidirectional lead screw B9.

[0026] The other side of the bidirectional lead screw B9 passes through the fixed base plate 1. One side of the bidirectional lead screw B9 is movably connected to the inner cavity of the fixed base plate 1 through a rotating joint. Two L-shaped protective rods 3 are threadedly connected to both sides of the bidirectional lead screw A4. A telescopic frame A10 is provided between the opposite sides of the two L-shaped protective rods 3. Clamping columns 11 are threadedly connected to both sides of the surface of the bidirectional lead screw B9. The opposite sides of the two clamping columns 11 are connected through a telescopic frame B.

[0027] When glass protection is required for transport, start drive motor 2. The output shaft of drive motor 2 drives the double-sided lead screw A4 to rotate. When the double-sided lead screw A4 rotates, it drives synchronous pulley A5 to move. Synchronous pulley A5 drives synchronous belt 7 to drive synchronous pulley B8 to rotate synchronously. Synchronous pulley B8 drives double-sided lead screw B9 to rotate. The rotation of double-sided lead screw A4 and synchronous belt 7 drive the two L-shaped protective rods 3 to move. Then, double-sided lead screw B9 drives the two clamping columns 11 to move relative to each other, adjusting them to the appropriate position for placing the glass. After adjustment, the worker places the glass onto this equipment.

[0028] Example 2

[0029] like Figures 5-7 As shown, the protective mechanism includes a transmission assembly 12, which is meshed with the other side of the bidirectional lead screw B9. A bevel gear 13 is meshed with one side of the upper end of the transmission assembly 12. A drive shaft 14 is fixedly connected to one side of the bevel gear 13. A rotating shaft 16 is slidably connected to one side of the surface of the drive shaft 14 through a limit strip A15.

[0030] A drive spline 18 is slidably connected to the surface of the rotating shaft 16 via a limiting strip B17. A push rod 19 is provided on the lower part of the other side of the drive spline 18. The push rod 19 is in active contact with the drive spline 18 and can be used to push the drive spline 18. An electric cylinder A20 is provided on the lower part of the other side of the push rod 19. The output shaft of the electric cylinder A20 is fixedly connected to the push rod 19. The lower part of the electric cylinder A20 is fixedly connected to the upper part of the telescopic frame.

[0031] A spur gear 21 is provided on one side of the surface of the rotating shaft 16. A spline groove is provided in the inner cavity of the spur gear 21, and the spline groove cooperates with the drive spline 18. A limit groove is provided on the other side of the spur gear 21. A roller 22 is movably connected to the inner cavity of the limit groove. A support rod 23 is movably connected to the other side of the roller 22. A positioning plate 24 is fixedly connected to the surface of the support rod 23. The positioning plate 24 is fixedly connected to the upper part of the telescopic frame B.

[0032] An electric cylinder B25 is fixedly connected to the upper part of the telescopic frame B on one side of the spur gear 21. A fixing plate 26 is fixedly connected to the output shaft of the electric cylinder. A push rod B27 is fixedly connected to the upper part of the other side of the fixing plate 26. A fixing rod 28 is provided on the other side of the fixing plate 26 below the push rod B27. A fixing groove is provided on one side of the spur gear 21. The fixing rod 28 and the fixing groove cooperate with each other.

[0033] One end of the spur gear 21 is meshed with a rack 29, and one end of the rack 29 is fixedly connected to a hollow protective frame 30. A sliding protective frame 31 is slidably connected to one side of the inner cavity of the hollow protective frame 30. The inner cavities of the sliding protective frame 31 and the hollow protective frame 30 are respectively provided with positioning grooves. Guide rods 6 are fixedly connected to opposite sides of the two clamping columns 11. The positioning grooves on the sliding protective frame 31 and the hollow protective frame 30 are slidably connected to the guide rods 6.

[0034] When the positions of the clamping column 11 and the L-shaped protective rod 3 need to be adjusted, the bidirectional lead screw B9 will drive the transmission assembly 12 to move, and the transmission assembly 12 will drive the bevel gear 13 to rotate. Then, the electric cylinder A20 will be activated, and the output shaft of the electric cylinder A20 will drive the push rod 19 to move. The push rod 19 will drive the drive spline 18 to move, moving the drive spline 18 into the interior of the spur gear 21, so that the spur gear 21 and the drive spline 18 are engaged. After the engagement is completed, the electric cylinder A20 will reset, and the bevel gear 13 will drive the drive shaft 14 to rotate. When the drive shaft 14 rotates, it can drive the limit bar A15 to drive the rotating shaft 16 to rotate, and the rotating shaft 16 will drive the limit bar B to drive the drive spline 18 to rotate. The drive spline 18 will drive the spur gear 21 to rotate, and when the spur gear 21 rotates, it can drive the rack 29 to drive the hollow protective frame 30. As the hollow protective frame 30 moves upward, it drives the sliding anti-slip frame to move. After the positions of the clamping column 11 and the L-shaped protective rod 3 are adjusted, the rack 29 stops moving. At this time, the hollow protective frame 30 is located at the top of the equipment. The electric cylinder B25 is activated, and the output shaft of the electric cylinder B25 drives the fixed plate 26 to move. The fixed plate 26 then drives the push rod and the fixed rod to move. The push rod pushes the drive spline 18 to the outside of the inner cavity of the flat gear 21. The fixed rod 28 then limits the flat gear 21. After the glass is placed, the electric cylinder B25 is activated again to reset its output shaft. Then, since the flat gear 21 and the rack 29 do not have a self-locking mechanism, the hollow protective frame 30 and the sliding protective frame 31 automatically reset to protect the side of the glass, preventing the glass from slipping out of the equipment due to tilting.
