Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to an elevator and a transfer system using the elevator. Background Art

[0002] The traditional way of conveying materials upward by elevators is generally through a fixed plate that can move up and down. The materials are placed on the fixed plate. After the fixed plate rises to a high level, the materials are pushed out, and then the fixed plate goes down to carry the materials, repeating the up and down movements. For example, the patent CN201921947691.0 for a reciprocating elevator discloses such a material lifting method. However, the speed of transporting materials in this way depends on the speed and distance of the fixed plate lifting and lowering. When working at a low level, the transfer efficiency is higher, while when working at a high level, the fixed plate takes a long time to move up and down each time, and the transfer efficiency is lower. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a lift.

[0004] The technical solution of this utility model is as follows:

[0005] A lift, comprising a frame, and further comprising:

[0006] The lifting system is installed in the frame and moves vertically to transfer materials to the top;

[0007] The pushing system comprises a pushing frame slidably connected to the frame up and down, a pushing part slidably connected to the bottom of the pushing frame, and the pushing part is connected to the power unit and moves forward and backward along the length direction of the pushing frame under the drive of the power unit;

[0008] The pushing part is located inside the lifting system, and its forward and backward movement does not interfere with the vertical movement of the lifting system.

[0009] The lifting system only transports materials, moves in one direction, and continuously transports materials upward. The pushing system can slide up and down to different layers, and continuously pushes out the materials transported by the lifting system. The cooperation between the two greatly improves the transfer efficiency, optimizes the traditional lifting system's up and down material transportation method, and has a consistent discharge speed, which is convenient for automatic control.

[0010] The frame is rectangular in style and includes four vertical supports. An upper support is connected to the top of the four vertical supports and a bottom support is connected to the bottom. A positioning system is provided above the bottom support. The positioning system is used for temporarily storing materials to facilitate the control of the uniform lifting position of the materials entering the frame.

[0011] The lifting system includes four first transmission chains distributed on four vertical supports. Between the outer rings of the front and rear transmission chains along the length direction of the pusher rack, a number of supporting parts are connected at intervals. The supporting parts are located outside the positioning system, and the supporting parts on the left and right sides of the positioning system are of the same height.

[0012] When the lifting system is working, the inner supporting parts of the first transmission chain move upward, and the outer supporting parts move downward. The supporting parts on the left and right sides of the positioning system move upward to continuously push up the temporarily stored materials on the positioning system and transport them to a higher place. As long as the upward speed and feeding speed of the lifting system are well controlled, it can be ensured that every time the material enters the predetermined position of the positioning system, a pair of supporting parts below will start to push the material upward, so that fast feeding can be guaranteed.

[0013] The power unit includes a second transmission chain arranged along the length direction of the pusher rack. The second transmission chain is controlled to rotate by a motor. A pushing part is connected below the chain. A slideway is arranged below the pusher rack. The second transmission chain drives the pushing part to move forward and backward along the slideway.

[0014] As a preferred embodiment, a chain supporting mechanism is further provided at the chain position under the second transmission chain to support the chain pin to prevent the chain from sagging.

[0015] The pusher system can be moved in the frame by means of a gear rack. The vertical support is provided with a rack inside the first transmission chain. The pusher frame is connected to the racks arranged vertically inside the first transmission chain on the four vertical supports through four limit gears. The teeth of the front and rear racks are arranged oppositely. In this way, the pusher system can be moved up and down, locked at any position, and prevented from shaking forward and backward.

[0016] In order to better limit the left and right shaking of the pushing system, a limiting roller is further arranged under the limiting gear on the pushing frame, and the limiting roller is in rolling contact with the inner side surface of the rack.

[0017] In order to further lock the position of the pusher system in the frame, a vertically arranged insert strip is provided on the back of the rack, and a number of insert holes are provided on the inner side of the insert strip. A locking cylinder is provided under the gear of the pusher frame, and the extension of the locking cylinder can be inserted into the insert hole. Through mechanical locking, in conjunction with the gear locking, the pusher system can be prevented from accidentally falling.

[0018] The present application also provides a transfer system, using the above-mentioned elevator, the bottom of the elevator is connected to the lower track through wheels, the front discharge side is connected to the storage device, and a first anti-tilt module is arranged between the elevator and the storage device, and the first anti-tilt module includes:

[0019] A clamping piece provided at the front of the discharge side of the top of the elevator;

[0020] A guide rail provided at the rear of the storage device;

[0021] The card connector is clamped on the front and rear sides of the guide rail.

[0022] As a preferred embodiment, at least two clips are provided, located at the left and right ends of the frame, and at least three rolling wheels are provided on the clips, which are respectively in rolling contact with the front, rear, upper or lower surface of the guide rail, thereby effectively preventing the tendency of tipping forward and backward and left and right.

[0023] When the elevator is moving, the upper part shakes the most. Through the design of the first anti-tilt module, the clamping part will conflict with the guide rail at the beginning of the tipping trend, thereby preventing the elevator from tipping.

[0024] As a more preferred embodiment, the top size of the lower track is larger than the middle size, and a second anti-tilt module is arranged at the bottom of the elevator. The second anti-tilt module includes a card plate, the upper end of which is connected to the elevator, and the lower end is provided with an opening matching the shape of the lower track, and is clamped on the lower track.

[0025] The lower track can be made of an I-beam style. After the pallet is stuck on the I-beam, the lower part reaches the middle position of the I-beam. When there is a tendency to tip forward or backward, the front or rear end of the pallet will be engaged with the lower track to provide reverse resistance to prevent the elevator from tipping over. When there is a tendency to tip left or right, the lower part of the pallet will flip sideways and be stuck at the bottom of the upper I-shaped surface of the I-beam, which will also prevent the elevator from tipping over.

[0026] In addition, a bottom fixing module is also provided at the bottom of the lift, and the bottom fixing module includes:

[0027] The base is located inside the lower track and fixed on the ground at different feeding positions;

[0028] The clamping unit is connected to the bottom of the lift and can be clamped on the base.

[0029] The bottom fixing module can provide a stable clamping force for the lift when it is working to prevent it from shaking in place. Moreover, when the lift slides to the predetermined position and brakes, it can also prevent it from sliding along the lower track under the action of inertia and causing position deviation.

[0030] Through the above design, the utility model lifter, through the mutual cooperation of the lifting system and the pushing system, greatly improves the transfer efficiency, optimizes the traditional lifting system's up and down material transportation method, and has a consistent discharge speed, which is convenient for automatic control.

[0031] The stability of the transfer system during movement and operation can be ensured by the first anti-tilt module, the second anti-tilt module and the bottom fixing module. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] See also Figure 1-Figure 3 A lift includes a frame 1, which is rectangular and includes four vertical supports 11. An upper support 12 is connected to the top of the four vertical supports 11, and a bottom support 13 is connected to the bottom. A positioning system 4 is arranged above the bottom support 13. The positioning system 4 is used for temporarily storing materials to facilitate the control of the uniform lifting position of materials entering the frame 1.

[0045] See also Figure 2 The positioning system 4 includes a positioning frame 41 fixed to the bottom support 13, on which a conveyor belt is arranged along the length direction of the frame 1, and side supports are provided on both sides of the conveyor belt, and a baffle 42 is fixed to the front end of the side support.

[0046] The material of this embodiment is introduced by taking the heat preservation board as an example. After the heat preservation board is conveyed to the frame 1, it is conveyed forward by the conveyor belt until it stops on the baffle 42. All the heat preservation boards can reach the same position.

[0047] In addition, the lift includes:

[0048] Lifting system 2, installed in frame 1, moves vertically and is used to transfer materials to the top, see Figure 5 .

[0049] The pushing system 3 includes a pushing frame 31 slidably connected to the frame 1, and a pushing part 33 is slidably connected to the bottom of the pushing frame 31. The pushing part 33 is connected to the power unit and moves forward and backward along the length direction of the pushing frame 31 under the drive of the power unit. Figure 4 .

[0050] The pushing portion 33 is located inside the lifting system 2 , and its forward and backward movement does not interfere with the vertical movement of the lifting system 2 .

[0051] The lifting system 2 only conveys materials, moves in one direction, and continuously conveys materials upwards, while the pushing system 3 can slide up and down to different layers, and continuously pushes out the materials conveyed by the lifting system 2. The mutual cooperation between the two greatly improves the transfer efficiency, optimizes the traditional lifting system 2 up and down material transport mode, and the material discharge speed is consistent, which is convenient for automatic control.

[0052] See also Figure 5 The lifting system 2 includes four first transmission chains 21, which are distributed on four vertical supports 11. Between the outer rings of the front and rear transmission chains along the length direction of the pushing rack 31, a plurality of supporting members 22 are connected at intervals. The supporting members 22 are located on the outside of the positioning system 4, and the supporting members 22 on the left and right sides of the positioning system 4 are of the same height.

[0053] When the lifting system 2 is working, the inner supporting member 22 of the first transmission chain 21 moves upward, and the outer supporting member 22 moves downward. The supporting members 22 on the left and right sides below the positioning system 4 move upward and continuously push up the temporarily stored materials on the positioning system 4 and transmit them to a higher place. As long as the upward speed and feeding speed of the lifting system 2 are well controlled, it can be ensured that every time the material enters the predetermined position of the positioning system 4, a pair of supporting members 22 below will start to push the material upward, so that fast feeding can be ensured.

[0054] See also Figure 7 The power unit includes a second transmission chain 32 arranged along the length direction of the pushing rack 31. The second transmission chain 32 is controlled to rotate by a motor. A pushing part 33 is connected below the chain. A slideway is provided below the pushing rack 31. The second transmission chain 32 drives the pushing part 33 to move forward and backward along the slideway.

[0055] The distance that the push part 33 moves forward and backward matches the length of the frame 1 , that is, the length of the second transmission chain 32 is greater than the length of the frame 1 , and the push part 33 is located outside the frame 1 when not working.

[0056] As a preferred embodiment, a chain supporting mechanism is further provided at the lower chain position of the second transmission chain 32 to support the chain pin to prevent the chain from sagging.

[0057] See also Figure 6-Figure 8 The pusher system 3 can be moved in the frame 1 by means of a gear rack 37. The vertical support 11 is provided with a gear rack 37 inside the first transmission chain 21. The pusher frame 31 is connected to the gear rack 37 vertically arranged inside the first transmission chain 21 on the four vertical supports 11 through four limit gears 34. The teeth of the front and rear gear racks 37 are arranged oppositely. In this way, the pusher system 3 can be moved up and down, locked at any position, and the forward and backward shaking of the pusher system 3 can be prevented.

[0058] Two sets of power units are arranged on the pusher rack 31, one set provides power for the second transmission chain 32, and the other set provides power for the rotation of the gear 34. The gear 34 is connected to the transmission shaft, and the transmission shaft is installed on the pusher rack 31 through the bearing seat. The power unit drives multiple transmission shafts to rotate synchronously.

[0059] In order to better limit the left and right shaking of the pushing system 3 , the pushing frame 31 is further provided with a limiting roller 35 below the fiber gear 35 , and the limiting roller 35 is in rolling contact with the inner side surface of the rack 37 .

[0060] In order to further lock the position of the pusher system 3 in the frame 1, a vertically arranged insert bar 38 is provided on the back of the rack 37, and a plurality of insert holes are provided on the inner side of the insert bar 38. A locking cylinder 36 is provided under the gear of the pusher frame 31, and the extension of the locking cylinder 36 can be inserted into the insert hole. Through mechanical locking, in conjunction with the gear locking, the pusher system 3 can be prevented from accidentally falling.

[0061] As a preferred embodiment, the side surface of the rack 37 is coplanar with the side surface of the insert 38, so that the limiting roller 35 contacts the sides of the rack 37 and the insert 38 to increase the contact area and improve the limiting ability of the limiting roller 35.

[0062] The present application also provides a transfer system, using the above-mentioned elevator, the bottom of the elevator is connected to the lower track through wheels, the front discharge side is connected to the storage device, and a first anti-tilt module 5 is arranged between the elevator and the storage device, see Figure 5 , the first anti-tilt module 5 comprises:

[0063] A clamping member 52 is provided at the front of the discharge side of the top of the elevator;

[0064] A guide rail 51 is provided at the rear of the storage device;

[0065] The clamping piece 52 is clamped on the front and rear sides of the guide rail 51 .

[0066] As a preferred embodiment, two clamping members 52 are provided, located at the left and right ends of the frame 1, and the clamping members 52 are provided with three rolling wheels, which respectively roll in contact with the front, rear and upper surfaces of the guide rail 51, thereby effectively preventing the tendency of tipping forward and backward and left and right.

[0067] When the elevator is moving, the upper part has the largest shaking amplitude. Through the design of the first anti-tilt module 5, when the tipping trend begins, the clamping member 52 will contact the guide rail 51, thereby preventing the elevator from tipping.

[0068] As a more preferred embodiment, the top size of the lower track is larger than the middle size, and a second anti-tilt module 6 is provided at the bottom of the elevator, see Figure 2 The second anti-tilt module 6 includes a card plate 61, the upper end of which is connected to the elevator, and the lower end of which is provided with an opening matching the shape of the lower track and is clamped on the lower track.

[0069] The lower track can be in the style of an I-beam. After the clamping plate 61 is clamped on the I-beam, the lower part reaches the middle position of the I-beam. When there is a tendency to tip forward or backward, the front or rear end of the clamping plate 61 will be clamped with the lower track to provide reverse resistance to prevent the elevator from tipping over. When there is a tendency to tip left or right, the lower part of the clamping plate 61 will flip sideways and be clamped on the bottom of the upper I-shaped surface of the I-beam, which will also prevent the elevator from tipping over.

[0070] In addition, a bottom fixing module 7 is also provided at the bottom of the lift, see Fig. 9 , the bottom fixing module 7 includes:

[0071] Base 74, located inside the lower track and fixed on the ground at different feeding stations;

[0072] The clamping unit, connected to the bottom of the elevator, can be clamped on the base 74.

[0073] The clamping unit includes a fixed seat fixed at the bottom of the lower support 13, and a push cylinder 73 rotatably connected to the lower support 13. The left and right ends below the fixed seat are rotatably connected to the first clamping jaw 71 and the second clamping jaw 72 respectively. The two clamping jaws are L-shaped structures, symmetrically arranged, and the turning points are rotatably connected to the fixed seat. The upper part of the first clamping jaw 71 is provided with a groove toward one end of the second clamping jaw 72, and the upper part of the second clamping jaw 72 is provided with a pin toward one end of the first clamping jaw 71. The pin is inserted into the groove. The rear part of the lower end of the second clamping jaw 72 is connected to the push cylinder 73, and the surface where the two clamping jaws and the push cylinder 73 are located is parallel to the lower track.

[0074] The two clamping jaws can be opened or closed by the telescopic action of the push cylinder 73. When the elevator moves on the lower track, the push cylinder 73 is controlled to push the two clamping jaws to open to prevent the clamping jaws from hitting the base 74. When reaching the predetermined position, the push cylinder 73 is controlled to drive the two clamping jaws to close so that the two clamping jaws are clamped on both sides of the base 74, thereby fixing the frame 1 to the ground.

[0075] The bottom fixed module 7 can provide a stable clamping force when the lift is working to prevent it from shaking in situ. Moreover, when the lift slides to the predetermined position and brakes, it can also prevent it from sliding along the lower track under the inertial force and causing position deviation.
