Description

Technical Field

[0001] The invention relates to the field of electric compact shelving, and in particular to an intelligent electric compact shelving emergency stop device. Background Art

[0002] Intelligent electric compact shelving is a modern storage device that integrates a variety of advanced technologies to achieve efficient management and access of archives.

[0003] There are usually multiple compact shelving units in the same track system, and all of them can move along the track to change the distance between two adjacent compact shelving units. When taking and placing items, the distance between the two can be increased to allow staff to enter; in the storage state, the distance between the two can be reduced to reduce the space occupied by the entire device. The compact shelving unit itself is relatively heavy, especially when it is fully loaded with items, so a relatively large kinetic energy drive is required to achieve the movement of the compact shelving unit. At the same time, the movement adjustment is achieved by rollers. After the emergency braking of the rollers, short-distance slippage is likely to occur due to inertia, and the emergency braking effect is relatively poor; and in the emergency braking state, the compact shelving unit is prone to tilting and may fall down. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an intelligent electric compact shelving emergency stop device.

[0005] The technical solution adopted by the present invention to solve its technical problem is: An intelligent electric compact shelving emergency stop device comprises two track structures, on which a compact shelving body is movably mounted via a movable structure, and a driving mechanism and a braking auxiliary mechanism are also mounted at the lower end of the compact shelving body; The track structure includes a bottom plate, a vertical plate is vertically welded at a position away from the center of the upper end of the bottom plate, a horizontally arranged horizontal plate is integrally connected to the upper end of the vertical plate, and a raceway is formed between the bottom plate, the vertical plate and the horizontal plate, and a toothed plate arranged along the length direction and located at the top of the raceway is fixed at the lower end of the horizontal plate; The movable structure is two sets distributed front and back, and any set of the movable structure has two sets. The movable structure includes two rollers rolling on the bottom plate, and one of the rollers is located in the rolling track; The driving mechanism is in transmission connection with one set of the moving structures, and is used to drive the moving structure to drive the compact shelving body to move along the length direction of the track structure; The braking auxiliary mechanism is transmission-connected to another set of the moving structures, and includes a gear that can mesh with the tooth plate, and can generate a rotation in the opposite direction to the roller when the compact shelving body is in a moving state when meshing, so as to drive the set of the moving mechanisms to generate a movement in the opposite direction to the compact shelving body to achieve emergency braking of the compact shelving body.

[0006] Preferably, the width of the bottom plate is greater than twice the width of the cross plate, and a positioning rail is fixed to the upper end of the bottom plate.

[0007] Preferably, the movable structure also includes a first mounting frame, which is fixed to the lower end of the compact shelving body, and a wheel axle is rotatably connected to the first mounting frame. The roller is fixed on the wheel axle, and the circumferential outer wall of the roller also has an annular groove, and the positioning track is embedded in the annular groove, and the tooth plate corresponds to the position of the annular groove.

[0008] Preferably, the distance between the roller and the transverse plate is less than 3 mm, while the distance between the tooth plate and the bottom of the annular groove is greater than 3 mm.

[0009] Preferably, the driving mechanism comprises a motor, the motor is fixed to the lower end of the compact rack body, and a first driving pulley arranged concentrically is fixed to the output end of the motor; In the moving structure drivingly connected to the driving mechanism, a first driven pulley arranged concentrically is fixed on the wheel shaft, and the first driven pulley and the first driving pulley are connected via a first transmission belt.

[0010] Preferably, the brake assist mechanism further comprises a second mounting frame, the second mounting frame is fixed to the lower end of the compact rack body, a cylinder is also fixed on the second mounting frame, the output end of the cylinder is vertically downward, and a third mounting frame is fixed on the output end, a fixed shaft extending to the inside of the raceway is fixed on the third mounting frame, a rotatable sleeve is sleeved on the fixed shaft, the gear is concentrically fixed to one end of the sleeve, and a concentrically arranged second driving pulley is fixed to the other end of the sleeve; In the moving structure drivingly connected to the brake assist mechanism, a second driven pulley arranged concentrically is fixed on the wheel axle, and the second driven pulley is connected to the second driving pulley via a second transmission belt.

[0011] Preferably, the cylinder is used to drive the gear to move in the vertical direction. When the gear moves to the highest position, it meshes with the toothed plate, and the second transmission belt is in a taut state.

[0012] Preferably, a through hole is also opened in the center of the gear, the aperture of which is larger than the diameter of the fixed shaft, and a torsion spring sleeved on the outside of the fixed shaft is fixed inside the through hole, and one end of the torsion spring is pressed against the third mounting frame to generate an elastic force opposite to the rotation direction of the gear when the gear rotates.

[0013] Preferably, a plurality of reinforcing plates are fixed to the circumferential outer wall of the sleeve, and the reinforcing plates, the gears and the second driving pulley are all fixed to each other.

[0014] Compared with the related art, the intelligent electric compact rack emergency stop device provided by the present invention has the following beneficial effects: 1. A rolling track for the rollers is formed between the bottom plate, the vertical plate and the horizontal plate to meet the needs of the rollers and limit one of the rollers. That is, when the roller is in an emergency braking state, the horizontal plate at the top limits the floating amount of the roller in the vertical direction to avoid the entire compact shelving from tilting and falling, thereby improving the stability of the compact shelving during emergency braking.

[0015] 2. When emergency braking is performed, the cylinder drives the gear upward to mesh with the toothed plate. Therefore, when the compact shelving continues to slide due to inertia, the gear meshing with the toothed plate will rotate and drive the second driving pulley to rotate through the sleeve. The second driving pulley drives the axle to rotate through the second transmission belt and the second driven pulley, causing the roller on the axle to rotate together. The direction in which the compact shelving is driven by the roller is opposite to the direction in which the compact shelving slides due to inertia, further enhancing the effect of emergency braking on the compact shelving.

[0016] 3. There is also a torsion spring between the gear and the fixed shaft. When the gear rotates, it will generate a force on the torsion spring and at the same time be subjected to a reaction force from the torsion spring. The elastic force of the torsion spring can buffer the slippage caused by inertia of the compact shelving, achieve a significant offset of inertia, and have a certain auxiliary effect on the braking of the compact shelving.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] See also Figures 1 to 10The present invention provides an intelligent electric compact shelving emergency stop device, which includes two track structures 1, a compact shelving body 2, a moving structure 3, a driving mechanism 4 and a braking auxiliary mechanism 5.

[0034] The compact shelving body 2 is installed on the track structure 1 through two sets of moving structures 3, and the driving mechanism 4 and the brake auxiliary mechanism 5 are fixed to the lower end of the compact shelving body 2 and are respectively connected to the two sets of moving structures 3 in transmission.

[0035] For track structure 1 and mobile structure 3, see Figures 2 to 4 The track structure 1 includes a base plate 11, a vertical plate 13 is vertically welded at a position away from the center of the upper end of the base plate 11, and a horizontally arranged cross plate 14 is integrally connected to the upper end of the vertical plate 13, and a raceway is formed between the base plate 11, the vertical plate 13 and the cross plate 14, and a tooth plate 15 arranged along the length direction and located at the top of the raceway is fixed at the lower end of the cross plate 14, and a positioning track 12 is also fixed at the upper end of the base plate 11.

[0036] Among them, the width of the bottom plate 11 is greater than twice the width of the cross plate 14; at the same time, the movable structure 3 includes a first mounting frame 31, the first mounting frame 31 is fixed to the lower end of the compact shelving body 2, and a wheel axle 32 is rotatably connected to the first mounting frame 31, and two rollers 33 are fixed on the wheel axle 32. The circumferential outer wall of the roller 33 also has an annular groove 34, and the positioning track 12 is embedded in the annular groove 34, and the tooth plate 15 corresponds to the position of the annular groove 34.

[0037] The distance between the roller 33 and the transverse plate 14 is less than 3 mm, while the distance between the tooth plate 15 and the bottom of the annular groove 34 is greater than 3 mm.

[0038] It should be noted that: in the mobile structure 3, the first mounting frame 31 is fixed to the lower end of the compact shelving body 2, and the roller 33 rolls on the base plate 11, thereby supporting the compact shelving body 2 and moving the compact shelving body 2; at the same time, a positioning track 12 is arranged at the upper end of the base plate 11, and the positioning track 12 is embedded in the annular groove 34 in the roller 33, so as to limit the roller 33 and make the connection between the two more compact.

[0039] There are two groups of rollers 33, one of which is located inside the raceway, and therefore can be restricted by the cross plate 14. That is, when the compact shelving body 2 makes an emergency stop, the cross plate 14 can be used to limit the displacement and floating amount of the roller 33 in the vertical direction, thereby avoiding the compact shelving body 2 from tilting at a large angle and preventing the compact shelving body 2 from tipping over.

[0040] The distance between the roller 33 and the cross plate 14 is less than 3 mm, while the distance between the tooth plate 15 and the bottom of the annular groove 34 is greater than 3 mm. Therefore, the maximum displacement of the roller 33 in the vertical direction is 3 mm. Within this range, the roller 33 will not contact the tooth plate 15, so it has a certain protective effect on both the roller 33 and the tooth plate 15.

[0041] For drive mechanism 4, see Figure 6 and Figure 7 The driving mechanism 4 includes a motor 41 , which is fixed to the lower end of the compact shelf body 2 , and a first driving pulley 42 which is concentrically arranged is fixed to the output end of the motor 41 .

[0042] In the moving structure 3 which is transmission-connected to the driving mechanism 4 , a first driven pulley 43 which is concentrically arranged is also fixed on the wheel shaft 32 , and the first driven pulley 43 and the first driving pulley 42 are connected via a first transmission belt 44 .

[0043] It should be noted that in the driving mechanism 4, the motor 41 can directly drive the first active pulley 42 to rotate, and then drive the wheel axle 32 to rotate through the first transmission belt 44 and the first driven pulley 43, and then drive the roller 33 to rotate, thereby realizing the movement of the entire compact shelving body 2.

[0044] When braking, the stop motor 41 operates to stop the rotation of the roller 33 and the movement of the compact shelving body 2 .

[0045] For brake assist mechanism 5, see Figures 8 to 10 The brake assist mechanism 5 includes a second mounting frame 51, which is fixed to the lower end of the compact shelving body 2. A cylinder 52 is also fixed on the second mounting frame 51, and the output end of the cylinder 52 is vertically downward, and a third mounting frame 53 is fixed at the output end. A fixed shaft 54 ​​extending to the inside of the raceway is fixed on the third mounting frame 53, and a rotatable sleeve 55 is sleeved on the fixed shaft 54. A gear 56 is fixed to one end of the sleeve 55, and a concentrically arranged second active pulley 57 is fixed to the other end of the sleeve 55. The cylinder 52 is used to drive the gear 56 to move in the vertical direction. When the gear 56 moves to the highest position, it meshes with the toothed plate 15, and the second transmission belt 511 is in a taut state.

[0046] In the mobile structure 3 which is transmission-connected to the brake assist mechanism 5 , a second driven pulley 510 which is concentrically arranged is also fixed on the wheel axle 32 , and the second driven pulley 510 and the second driving pulley 57 are connected via a second transmission belt 511 .

[0047] At the same time, a through hole is also opened in the center of the gear 56. The aperture of the through hole is larger than the diameter of the fixed shaft 54, and a torsion spring 59 is fixed inside the through hole and is sleeved on the outside of the fixed shaft 54. One end of the torsion spring 59 is pressed against the third mounting frame 53 to generate an elastic force in the opposite direction of rotation to the gear 56 when the gear 56 rotates.

[0048] A plurality of reinforcing plates 58 are fixed to the circumferential outer wall of the sleeve 55 , and the reinforcing plates 58 , the gear 56 , and the second driving pulley 57 are all fixed to each other.

[0049] It should be noted that: in the brake assist mechanism 5, the cylinder 52 can drive the third mounting frame 53 to perform lifting movement, and drive the sleeve 55 and the gear 56 to move together through the fixed shaft 54, so as to realize the lifting and lowering adjustment of the gear 56. When the gear 56 moves to the highest position, it can mesh with the toothed plate 15; and if the compact shelving body 2 slips due to inertia, the gear 56 will rotate, and then drive the second driving pulley 57 to rotate together through the sleeve 55. The second driving pulley 57 drives the axle 32 to rotate together through the second transmission belt 511 and the second driven pulley 510, and then drives the roller 33 on the axle 32 to rotate, and the rotation direction of the roller 33 is opposite to the slip direction of the compact shelving body 2, thereby improving the grip of the roller 33, thereby further improving the braking effect of the device.

[0050] A torsion spring 59 is also provided between the gear 56 and the fixed shaft 54. When the gear 56 rotates, a force is applied to the torsion spring 59, and at the same time, a reaction force is exerted by the torsion spring 59. The elastic force of the torsion spring 59 can buffer the slippage caused by inertia of the compact shelving, thereby achieving a significant offset of inertia and having a certain auxiliary effect on the braking of the compact shelving.

[0051] When the gear 56 is in the highest position, it is meshed with the tooth plate 15, and the gear 56 and the second driving pulley 57 are also installed on the sleeve 55, so the second driving pulley 57 will also be displaced relative to the second driven pulley 510. At this time, the distance between the two will increase, so that the second transmission belt 511 is in a taut state, so that transmission can be achieved between the second driving pulley 57 and the second driven pulley 510; and after the compact shelving body 2 is stagnant, the gear 56 is driven downward by the cylinder 52 to disengage it from the tooth plate 15, and at the same time, the second transmission belt 511 is converted from a taut state to a relaxed state. In this state, transmission cannot be achieved, so the sleeve 55 is basically not subject to any restriction, and the torsion spring 59 can release the accumulated elastic potential energy and return to the initial state.

[0052] As for the reinforcing plate 58, it is fixed to the outside of the sleeve 55 and is connected to the gear 56 and the second driving pulley 57, which can further improve the strength of the sleeve 55, reduce the torque applied to the sleeve 55, and improve the service life of the device.

[0053] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
