Description

Technical Field

[0001] This utility model belongs to the field of logistics equipment technology, specifically relating to a dual-station lifting and transferring machine. Background Technology

[0002] A lifting transfer machine is a device used to change the direction of goods transport, moving items from forklifts into or out of the main conveyor line. It can achieve right-angle turns even in space-constrained conditions, offering space-saving advantages. Existing lifting transfer machines generally use a motor and drive chain to rotate cams on the base frame module. The rotation of the cams lifts the lifting idler wheels fixed to the upper frame, thus achieving the lifting and lowering action of the machine.

[0003] However, this structure has high requirements for the coaxiality of the cams, and there is gear backlash between the chain and sprocket, making synchronization difficult. If the cams cannot synchronously lift the entire upper frame, the lifting and transfer machine may jam or vibrate during lifting. Therefore, there is an urgent need to design a dual-station lifting and transfer machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a dual-station lifting and transferring machine to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-station lifting and transferring machine, comprising:

[0006] The lower frame has mounting blocks fixed at its four corners and several mounting longitudinal beams fixed on it.

[0007] The lifting mechanism includes a synchronous lifter fixed to the top of the mounting block, a motor and a steering box fixed to the top of the mounting longitudinal beam. The output shaft of the motor is connected to the input shaft of the steering box via a coupling. A transmission shaft is provided between the synchronous lifter and the steering box. The input shaft of the synchronous lifter is connected to one end of the transmission shaft via a coupling, and the output shaft of the steering box is connected to the other end of the transmission shaft via a coupling.

[0008] The upper frame has four corners that are fixedly connected to the top plates of the four synchronous lifters, and mounting beams are fixed on both sides of the top of the upper frame.

[0009] The transfer mechanism consists of two parts, which are sequentially fixed to the top of the mounting beam.

[0010] Furthermore, it also includes a proximity switch module, which includes a mounting plate one fixed to the lower frame and a mounting plate two fixed to the upper frame. Two proximity switches are fixed on the mounting plate one along the vertical direction, and a baffle corresponding to the proximity switch is provided on one side of the mounting plate two.

[0011] Furthermore, the synchronous lifter is a worm gear screw jack, which includes a housing, a worm, a worm wheel, a lead screw, a nut, and a top plate. The worm is connected to the drive shaft via a coupling, the worm is connected to the worm wheel via a drive connection, the worm wheel is connected to the lead screw via a key, the lead screw is threadedly engaged with the nut, the nut is fixed to the top of the housing, and the top plate is fixed to the top of the lead screw.

[0012] Furthermore, there are three steering gearboxes in total, and all three steering gearboxes are either dual-output bevel gear steering gearboxes or dual-output worm gear steering gearboxes.

[0013] Furthermore, the transfer mechanism includes chain frames fixed to both ends of the top of the mounting beam. Each end of the chain frame is provided with a transfer sprocket. The two transfer sprockets are connected by a transfer chain. A shelf is fixed between the two chain frames. A flow bar is provided in the middle of the shelf. The flow bar is parallel to the transfer chain and has the same horizontal height at the top.

[0014] Furthermore, the transfer mechanism also includes a mounting frame fixed to the bottom of the chain frame. A support plate is fixed on the mounting frame, and a second motor is fixed on the support plate. A second drive shaft is provided on one side of the second motor. The second drive shaft has three drive sprockets. Two of the drive sprockets are respectively engaged with their corresponding two transfer chains, and the other drive sprocket corresponds to the sprocket on the output shaft of the second motor and is connected to it through a drive chain.

[0015] Furthermore, the lower frame is provided with fasteners at its four corners, the fasteners including angle irons welded to the lower frame and bolts that penetrate the angle irons and are fixedly connected to the ground.

[0016] The technical effects and advantages of this utility model are as follows: This dual-station lifting and transferring machine has an advanced design, compact structure, is easy to use, and reliable operation. By replacing the cam lifting mechanism with a synchronous lifter, the assembly requirements are lower and the synchronization adjustment is simpler. Workers only need to adjust the mounting surfaces of the synchronous lifters at the four corners to be relatively level. During the lifting process, there will be no jamming or shaking of the upper frame. Moreover, increasing the lifting stroke only requires increasing the stroke of the lead screw. Since the lever arm remains unchanged, there is no need to replace it with a higher-power motor. The installation and maintenance costs are low. In addition, the synchronous lifter has a certain self-locking capability, which can lock the entire upper frame in the stop position when the motor stops, eliminating the risk of goods falling.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] This utility model provides, for example Figure 1-6 The dual-station lifting and transferring machine shown includes:

[0028] The lower frame 100 has mounting blocks 101 fixed at its four corners and several mounting longitudinal beams 102 fixed on it.

[0029] The lifting mechanism 200 includes a synchronous lifter 201 fixed to the top of the mounting block 101, and a motor 202 and a steering box 203 fixed to the top of the mounting longitudinal beam 102. The output shaft of the motor 202 is connected to the input shaft of the steering box 203 through a coupling 204. A transmission shaft 205 is provided between the synchronous lifter 201 and the steering box 203. The input shaft of the synchronous lifter 201 is connected to one end of the transmission shaft 205 through a coupling 204. The output shaft of the steering box 203 is connected to the other end of the transmission shaft 205 through a coupling 204. The power of the motor 202 is transmitted to the steering box 203, and after being turned by the steering box 203, it is transmitted to the transmission shaft 205. Finally, the transmission shaft 205 transmits the power to the synchronous lifter 201.

[0030] The upper frame 300 has four corners that are fixedly connected to the top plates of four synchronous lifters 201. The top two sides of the upper frame 300 are fixed with mounting beams 301, which facilitates the lifting of the four corners of the upper frame 300 by the four synchronous lifters 201, making the lifting process more stable.

[0031] There are two transfer mechanisms 400. The two transfer mechanisms 400 are fixed to the top of the mounting beam 301 in sequence. The two transfer mechanisms 400 serve as two transfer stations and can perform transfer operations at the same time, which helps to improve the working efficiency of the transfer machine.

[0032] For example, see Figure 1 and Figure 5As shown, it also includes a proximity switch module 500. The proximity switch module 500 includes a mounting plate 501 fixed to the lower frame 100 and a mounting plate 502 fixed to the upper frame 300. Two proximity switches 503 are fixed on the mounting plate 501 along the vertical direction. A baffle 504 corresponding to the proximity switch 503 is provided on one side of the mounting plate 502.

[0033] In this technical solution, the lifting mechanism 200 drives the upper frame 300 to descend. When the baffle 504 descends to the side of the proximity switch 503 at the lower position, the upper frame 300 descends to the lowest position. At this time, the motor 202 stops running. The lifting mechanism 200 drives the upper frame 300 to rise. When the baffle 504 rises to the side of the proximity switch 503 at the higher position, the upper frame 300 rises to the highest position. At this time, the motor 202 stops running. The rising or falling of the lifting mechanism 200 can be automatically limited.

[0034] For example, see Figure 1 As shown, the synchronous lift 201 is a worm gear screw jack. The synchronous lift 201 includes a housing, a worm, a worm wheel, a lead screw, a nut, and a top plate. The worm is connected to the drive shaft 205 through a coupling 204. The worm is connected to the worm wheel via a drive connection. The worm wheel is connected to the lead screw via a key. The lead screw is threadedly engaged with the nut. The nut is fixed to the top of the housing, and the top plate is fixed to the top of the lead screw.

[0035] In this technical solution, the power of motor 202 is transmitted to the worm gear through transmission shaft 205. The worm gear drives the worm wheel to rotate, and the worm wheel drives the lead screw to rotate. Since the nut cannot move, the rotating lead screw is forced to move along its own axis (i.e., up and down), thereby driving the top plate to move up and down and achieving the lifting of the upper frame 300. In addition, the synchronous lifter 201 can also be a trapezoidal thread lead screw jack or a ball screw jack. It should be noted that when using a trapezoidal thread lead screw jack, the lead angle of the trapezoidal thread should be designed to be small, so that the friction angle between the threads is greater than the lead angle, to ensure that it has self-locking capability. When using a ball screw jack, an additional brake (motor brake) or a self-locking reduction mechanism must be equipped to prevent the load from falling.

[0036] For example, see Figures 3-4 and Figure 6 As shown, there are three steering gearboxes 203 in total. All three steering gearboxes 203 are either dual-output bevel gear steering gearboxes or dual-output worm gear steering gearboxes.

[0037] In this technical solution, the steering box 203 is a gearbox used to transmit power from the horizontal direction to the vertical direction (or other angles). Through the cooperation of three steering boxes 203 and drive shaft 205, the power of motor 202 can be transmitted to the synchronous lifters 201 at the four corners of the lower frame 100, ensuring that the four synchronous lifters 201 can achieve synchronous lifting.

[0038] For example, see Figure 1 and Figures 5-6 As shown, the transfer mechanism 400 includes chain frames 401 fixed to both ends of the top of the mounting beam 301. The two ends of the chain frames 401 are provided with transfer sprockets 402. The two transfer sprockets 402 are connected by transfer chains 403. A shelf 404 is fixed between the two chain frames 401. A flow bar 405 is provided in the middle of the shelf 404. The flow bar 405 is arranged parallel to the transfer chain 403 and the top horizontal height is the same.

[0039] In this technical solution, the goods are placed on the top of the shelf 404. At this time, the bottom of the goods is in contact with the top of the transfer chain 403 and the flow bar 405 respectively. When the transfer chain 403 rotates, the goods can be moved along the rotation direction of the transfer chain 403. The flow bar 405 can support the goods and assist in the conveying.

[0040] For example, see Figures 1-4 As shown, the transfer mechanism 400 also includes a mounting bracket 406 fixed to the bottom of the chain frame 401. A support plate 407 is fixed on the mounting bracket 406, and a second motor 408 is fixed on the support plate 407. A second drive shaft 409 is provided on one side of the second motor 408. A total of three drive sprockets 410 are provided on the second drive shaft 409. Two of the drive sprockets 410 are respectively engaged with their corresponding two transfer chains 403, and the other drive sprocket 410 corresponds to the sprocket on the output shaft of the second motor 408 and is connected through a drive chain 411.

[0041] In this technical solution, motor 2 408 drives transmission shaft 2 409 to rotate via transmission chain 411, and transmission shaft 2 409 drives transfer chain 403 to rotate via transmission sprocket 410, thereby providing power support for the transfer of goods.

[0042] For example, see Figure 1 As shown, the lower frame 100 is provided with fasteners 103 at the four corners. The fasteners 103 include angle irons welded to the lower frame 100 and bolts that penetrate the angle irons and are fixedly connected to the ground.

[0043] In this technical solution, the lower frame 100 can be fixed on the ground, which helps to improve the structural stability of the dual-station lifting and transferring machine.

[0044] Working principle: When using this dual-station lifting and transferring machine, the goods are first transported to the shelf 404. Then, motor 202 is started. Motor 202 drives the drive shaft 205 to rotate through the steering box 203. The drive shaft 205 then transmits power to the synchronous lifters 201. The four synchronous lifters 201 simultaneously lift the four corners of the upper frame 300. By controlling the forward and reverse rotation of the output shaft of motor 202, the upper frame 300 and the goods on it are moved up and down. Then, motor 408 is started. Motor 408 drives the transfer chain 403 to rotate through the drive shaft 409, thereby transferring the goods on the shelf 404 to the designated position, thus completing the lifting and transferring operation. This dual-station lifting and transferring machine features an advanced design, compact structure, ease of use, and reliable operation. By replacing the cam lifting mechanism with a synchronous lifter 201, assembly requirements are lowered, and synchronization adjustment is simpler. Workers only need to adjust the mounting surfaces of the synchronous lifters 201 at the four corners to be relatively level. During the lifting process, there will be no jamming or shaking of the upper frame 300. Moreover, increasing the lifting stroke only requires increasing the travel of the lead screw, and since the lever arm remains unchanged, there is no need to replace it with a higher-power motor 202. The installation and maintenance costs are low. In addition, the synchronous lifter 201 has a certain self-locking capability, which can lock the entire upper frame 300 in the stop position when the motor 202 stops, eliminating the risk of goods falling.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
