[0030] like Figure 1-Figure 4 and Figure 6 As shown, a trigger plate 2 is slidably fitted at the bottom of the support body, a distance sensor 3 is mounted on the trigger plate 2, and the detection portion of the distance sensor 3 is arranged toward the support body; a motor 11 and a threaded rod 4 are rotatably arranged on the housing, the motor 11 is a servo motor, the motor 11 can rotate forward and reversely, the output end of the motor 11 is linked with the threaded rod 4, a reducer is arranged on the output end of the motor 11, the reducer is not drawn, and the output end of the reducer is linked with the threaded rod 4; an electrically controlled telescopic clamp is mounted on one of the telescopic plates, the engaging portion of the electrically controlled telescopic clamp is engaged with the spiral groove of the threaded rod 4, and the electrically controlled telescopic clamp and its upper adjacent support The distance sensor 3 on the support body is electrically connected; the electrically controlled telescopic clamp includes a first electric telescopic rod 16, which is installed on the drawer plate 13 near the second side guard plate 8. The first electric telescopic rod 16 is electrically connected to the distance sensor 3 on the support body adjacent to it above. A clamp 17 is fixedly connected to the free end of the first electric telescopic rod 16. When the clamp 17 extends into the interior of the positioning ring and engages with the spiral groove of the threaded rod 4, the motor 11 is started to rotate the threaded rod 4 forward or reversely. The concave block 14 and the slide rail 15 are used to make the drawer plate 13 rise or fall, that is, the sleeve plate 12 rises or falls with the support body.

[0031] like Figure 1 and Figure 5As shown, a rack 5 is slidably matched on the shell, a slide groove 18 is provided on the first side guard plate 7 and the second side guard plate 8, the rack 5 is slidably matched with the slide groove 18, a first spring 19 is installed between the rack 5 and the inner wall of the slide groove 18, a first electromagnet 20 is installed on the inner wall of the slide groove 18, and a second electromagnet 21 is installed on the rack 5. The first electromagnet 20 and the second electromagnet 21 are magnetically attracted to each other. The magnetic attraction between the first electromagnet 20 and the second electromagnet 21 is a prior art, and the magnetic attraction strength can be adjusted by adjusting the current intensity on the first electromagnet 20 and the second electromagnet 21; when the first electromagnet 20 and the second electromagnet 21 are magnetically attracted to each other, Figure 5 As shown, the rack 5 slides to the left along the slide slot 18 and compresses the first spring 19 .

[0032] like Figure 1 , Figure 5 and Figure 6 As shown, a one-way gear is installed on the telescopic plate, and the rack 5 is engaged with the one-way gear; the one-way gear includes a one-way bearing 22, which is installed on the draw plate 13, and a gear 23 is coaxially connected to the one-way bearing 22. Through the setting of the one-way bearing 22, the gear 23 can only rotate in one direction; the rack 5 is meshed with the gear 23, and an angle sensor 24 is installed on the gear 23, and the first electric telescopic rod 16 is electrically connected to the angle sensor 24; when the rack 5 is meshed with the gear 23, the motor 11 is started to make the support body rise, and the gear 23 rotates continuously. The angle sensor 24 can detect the number of rotations of the gear 23, and the height of the support body can be monitored. When the angle sensor 24 detects that the gear 23 rotates to the set number of circles, it is regarded that the support body has risen to the set height, and the angle sensor 24 controls the corresponding first electric telescopic rod 16 to retract, and the clamping head 17 is no longer engaged with the spiral groove of the threaded rod 4, that is, the support body stops rising; it should be noted that since the gear 23 can only rotate in one direction, it can prevent the support body from sliding down.

[0033] like Figure 1 , Figure 4 and Figure 6As shown, the support body includes a support frame 25, on which a plurality of conveying rollers 26 are rotatably connected, and a support plate 27 is slidably provided inside the support frame 25, the support plate 27 is located below the conveying rollers 26, and a clearance groove 40 matching the conveying rollers 26 is provided on the top of the support plate 27, and a non-slip surface is provided on the top of the support plate 27; a second electric telescopic rod 28 is installed on the support plate 27, and a free end of the second electric telescopic rod 28 is fixedly connected to the support frame 25; through the provision of the conveying rollers 26, it is convenient for the staff to place the carton (especially when the carton contains heavy items, the physical strength of the staff is greatly saved by utilizing the rolling characteristics of the conveying rollers 26), after the carton is located on the conveying rollers 26, the second electric telescopic rod 28 is started and its free end is retracted, the support plate 27 rises and enables the conveying rollers 26 to enter the inside of the clearance groove 40, and the support plate 27 rises and presses against the bottom of the carton, and the friction between the support plate 27 and the carton is used to fix the position of the carton.

[0034] A movable groove is provided at the bottom of the support plate 27, and the trigger plate 2 is slidably matched with the movable groove. The detection part of the distance sensor 3 is arranged toward the inner top wall of the movable groove, and a second spring 29 is installed between the trigger plate 2 and the inner top wall of the movable groove; both ends of the support frame 25 are provided with hinge shafts, and the two hinge shafts are rotatably connected with the two sleeve plates 12 respectively; it should be noted that the rising height of each support frame 25 is set in advance, but due to factors such as different carton heights and operational errors, when the rising height is set incorrectly, for example, during the rising process of the second support frame 25 from the top (at this time, the second support frame 25 from the top The first support frame 25 is in a stationary state), and when it rises to the point where the carton it carries touches the trigger plate 2 above (the trigger plate 2 on the first support frame 25 from the top), the trigger plate 2 rises along the movable groove, and the distance between the corresponding distance sensor 3 and the top wall in the movable groove decreases. The distance sensor 3 controls the second electric telescopic rod 28 corresponding to the second support frame 25 from the top to retract, even if the support frame 25 stops rising, to prevent the carton from continuing to rise and causing damage to the carton and the items in the carton. The device has an emergency stop function, which improves the practicability of the device.

[0035] like Figure 2 As shown, an inclination measuring device 10 is installed on the housing. The inclination measuring device 10 is an electronic angle measuring instrument. The inclination measuring device 10 is electrically connected to a motor 11 .

[0036] like Figure 1 , Figure 3 and Figure 8As shown, it also includes a locking mechanism for fixing the positions of the two telescopic plates and the supporting body relatively, and the rack 5 is driven and cooperated with the locking mechanism; the locking mechanism includes a locking rod 30 that is laterally slidably arranged on the sleeve plate 12, and the sleeve plate 12 is provided with a mounting groove 31, and the locking rod 30 passes through the mounting groove 31, and a guide block 32 is fixedly connected to the locking rod 30 located in the mounting groove 31, and an elastic block 33 is installed between the guide block 32 and the inner wall of the mounting groove 31; one end of the hinge shaft passes through the sleeve plate 12 and its end is coaxially fixedly connected with a locking wheel 34, one end of the locking rod 30 is provided with a locking block 35, the locking wheel 34 is embedded with the locking block 35, and the other end of the locking rod 30 corresponds to the rack 5.

[0037] When the two racks 5 respectively press against the two locking rods 30, the locking rod 30 moves with the guide block 32 close to the locking wheel 34, and at the same time the elastic block 33 is compressed, and the locking block 35 is stuck in the tooth groove of the locking wheel 34, so that the two telescopic plates are relatively fixed to the support body.

[0038] like Figure 1 , Figure 3 and Figure 7 As shown, a plurality of caster groups are provided at the bottom of the base frame 1, one of which is provided with a non-return mechanism, the caster group is composed of two casters 6 and a center rod 36, the casters 6 are installed at the bottom of the base frame 1, and the two casters 6 are coaxially connected to the center rod 36; the non-return mechanism includes a ratchet 37 coaxially fixed on the center rod 36, a connecting rod 38 is fixedly connected to the rack 5, a positioning block 39 is fixedly connected to the bottom end of the connecting rod 38, and the positioning block 39 is engaged with the tooth groove of the ratchet 37.

[0039] When the device is transporting cartons on an uphill section, the rack 5 slides with the linkage rod 38 until the positioning block 39 is engaged with the tooth groove of the ratchet 37. At this time, the ratchet 37 can only rotate forward, that is, the caster 6 can only rotate forward, to prevent the device from slipping during the uphill transportation process.

[0040] It should be noted that the device is provided with a control system (such as a PLC controller), and the distance sensor 3, the motor 11, the first electric telescopic rod 16, the first electromagnet 20, and the second electromagnet 21 are all electrically connected to the control system.

[0041] The working process of the device for isolating the carton from the ground: in the initial state, the first electromagnet 20 and the second electromagnet 21 are both in the off-state, at this time, the first spring 19 is in the unfolded state, the rack 5 and the gear 23 are in the meshing state, and the rack 5 is against the locking rod 30, the elastic block 33 is compressed and the locking block 35 is stuck in the tooth groove of the locking wheel 34, at this time, the position of the sleeve plate 12 and the support frame 25 is relatively fixed.

[0042] First, start the motor 11 to make the threaded rod 4 rotate in the forward direction. After placing the carton on the support frame 25, start the corresponding first electric telescopic rod 16 and extend its free end. The free end of the first electric telescopic rod 16 drives the clamping head 17 to extend into the spiral groove of the threaded rod 4. Then, by using the setting of the concave block 14 and the slide rail 15, the drawer plate 13 is raised, that is, the sleeve plate 12, the support frame 25 and the carton are all raised.

[0043] During the rising process of the support frame 25 and the carton, the gear 23 rotates continuously, and the angle sensor 24 can detect the number of rotations of the gear 23, thereby monitoring the rising height of the support body. When the angle sensor 24 detects that the gear 23 has rotated to the set number of rotations, it is considered that the support body has risen to the set height, and the angle sensor 24 transmits a signal to the control system. The control system controls the corresponding first electric telescopic rod 16 to retract, that is, the clamping head 17 no longer engages with the spiral groove of the threaded rod 4, and the support frame 25 and the carton stop rising; it should be noted that since the gear 23 can only rotate in one direction, the support frame 25 and the carton will not slide down.

[0044] It is worth noting that the multiple support frames 25 on the device rise step by step from top to bottom, that is, after a certain support frame 25 rises, the adjacent support frame 25 below it can be loaded with cartons and rise; by placing cartons on each support frame 25 and lifting them, the cartons are stacked and isolated from the ground, and the cartons are moisture-proof.

[0045] It should be noted that the rising height of each support frame 25 is set in advance, but it is affected by factors such as different carton heights and operational errors. When the rising height is set incorrectly, for example, during the rising process of the second support frame 25 from the top, when it rises to the point where the carton it carries hits the trigger plate 2 above, the trigger plate 2 rises along the movable groove, and the distance between the corresponding distance sensor 3 and the top wall of the movable groove decreases. The distance sensor 3 transmits a signal to the control system, and the control system controls the second electric telescopic rod 28 corresponding to the second support frame 25 from the top to retract, that is, the support frame 25 no longer rises to prevent the carton from continuing to rise and causing damage to the carton and the items inside the carton.

[0046] The device moves in an uphill or downhill section as follows: first, the first electromagnet 20 and the second electromagnet 21 are energized, the first electromagnet 20 and the second electromagnet 21 are magnetically attracted to each other, the rack 5 slides in the slide groove 18 and compresses the first spring 19, and at the same time, the elastic block 33 releases force to push the guide block 32 away from the locking wheel 34, the locking rod 30 follows the movement of the guide block 32 and disengages the locking block 35 from the locking wheel 34, and at this time, the positions of the sleeve plate 12 and the support frame 25 are no longer relatively fixed.

[0047] It is worth noting that the current intensity of the first electromagnet 20 and the second electromagnet 21 close to the second side guard plate 8 needs to meet the requirements that the rack 5 slides to disengage from the corresponding gear 23, and the connecting rod 38 moves to the positioning block 39 and the tooth groove of the ratchet 37.

[0048] When the device enters an uphill section, the first side guard plate 7 is located at the front end, the inclination measuring device 10 detects the inclination of the device and transmits a signal to the control system, the control system controls the free ends of the second electric telescopic rods 28 near the second side guard plate 8 to extend, the corresponding clamping heads 17 are engaged with the spiral grooves of the threaded rods 4, and the motor 11 is controlled to rotate forwardly. The rotation amount of the motor 11 is determined according to the inclination detected by the inclination measuring device 10, so that the draw plates 13 near the second side guard plate 8 are all raised, the sleeve plate 12 is hingedly arranged with the support frame 25, and the sleeve plate 12 can slide on the draw plates 13, so that Figure 1 As shown in the figure, the support frame 25 is turned counterclockwise so that the support frame 25 is in a horizontal state.

[0049] It should be noted that when the device is transporting cartons on an uphill section, the positioning block 39 and the ratchet 37 are in an engaged state. At this time, the ratchet 37 can only rotate forward, that is, the caster 6 can only rotate forward, to prevent the device from slipping during the uphill transportation process.

[0050] When the device enters a downhill section, the motor 11 is controlled to rotate in the opposite direction according to the above principle, so that the drawer 13 close to the second side guard plate 8 is lowered. Figure 1 As shown, the support frame 25 is flipped clockwise to make the support frame 25 in a horizontal state; when the device is used to transport cartons on uphill or downhill sections, the support frame 25 is in a horizontal state to prevent the cartons from slipping due to transportation in an inclined state.
