Description
Technical Field
The embodiment of the invention relates to the field of transportation equipment, in particular to a worm and gear driving type carrying device.
Background
With the development of warehousing technology, the handling equipment such as the shuttle car gradually replaces the mode that a forklift drives into the goods shelf to store and take goods. The reason for this is that traditional fork truck is bulky, reserves very big space for fork truck between the goods shelves, and when accomplishing these tasks by the shuttle, can effectively reduce the interval between the goods shelves, realizes very high storage space utilization.
Briefly, the shuttle type warehousing system adds high-precision guide rails to a traditional goods shelf to enable a shuttle vehicle to stably run on the rail, and the shuttle vehicle is an intelligent robot which has a lifting function, so that the shuttle vehicle can achieve tasks such as taking, transporting, placing and the like on the rail, for example, the shuttle vehicle moves on the goods shelf rail in a reciprocating or loop-back mode to transport goods to a designated place and return the goods. In order to make full use of space, the common rail has an L-shaped rail in addition to a straight line shape, and therefore, the shuttle vehicle also needs a reversing function.
Conventional handling equipment (shuttle) is wheeled in at least two directions (e.g., orthogonal directions) on a track and jacking is accomplished by two different mechanisms, resulting in high equipment height and heavy weight. The carrying equipment needs a plurality of mechanisms capable of completing driving, reversing and jacking actions, and also needs components such as a power supply, a sensor, a controller and the like, so that the requirement on the reasonable arrangement of the self space of the shuttle car is extremely high.
Therefore, how to make the haulage equipment volume thin as far as possible (the automobile body is thinner, warehouse space utilization is higher), light as far as possible in weight (the automobile body is lighter, the requirement for goods shelves load is smaller, the operation energy consumption is lower), whole motion energy consumption is low (the energy consumption is lower, battery duration is longer), the switching-over jacking time is short (the time spent is shorter, car efficiency is higher), equipment itself needs frequent mechanical switching-over and jacking motion, mechanical structure design is more wear-resistant reasonable (the structure is more reasonable wear-resistant, the life-span is longer) is the urgent problem that waits to solve in this field.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic structural diagram of a handling apparatus according to a first embodiment of the present invention, and fig. 2 is a schematic internal connection structural diagram of the handling apparatus according to the first embodiment of the present invention. As shown in fig. 1 and 2, a carrying apparatus in an embodiment of the present invention includes: the main frame 10, the lifting frame body 20, the first travel driving device 30, the first transmission shaft 40, the first rotating wheel 50, the second travel driving device 60, the second transmission shaft 70, the second rotating wheel 80, a lifting transmission mechanism (not shown) and a worm motor 96. The handling device in this embodiment is a shuttle car which may be arranged on a track of the rack, the track comprising a first track and a second track connected end to end, the first track and the second track being non-parallel to each other, e.g. the first track and the second track being at an acute or right angle. The main frame body and the lifting frame body can be a shell or a frame made of metal or plastic. The first walking driving device and the second walking driving device can be ordinary motors, servo motors, stepping motors and the like, and the first transmission shaft and the second transmission shaft are straight shafts. In addition, it should be noted that the number of the first rotating wheel and the second rotating wheel is at least one, and the two wheels which are most convenient to understand are taken as an example in the present embodiment.
Specifically, in the present embodiment, the first transmission shaft 40 is disposed on the main frame 10, through holes are disposed on the side walls of the main frame, bearings are disposed in the through holes, and both ends of the first transmission shaft are disposed on the bearings on both sides, respectively. The first rotating wheels 50 are fixedly disposed on the first transmission shaft 40, that is, two first rotating wheels are respectively disposed at two ends of the first rotating shaft. The first travel driving device 30 is connected to the first transmission shaft 40 and is configured to drive the first transmission shaft 40 to rotate. The lifting frame body 20 is connected with the main frame body 10 through a lifting transmission mechanism, and the worm motor 96 is connected with the lifting transmission mechanism and used for triggering the lifting transmission mechanism and enabling the lifting frame body 20 to ascend or descend to a preset position relative to the main frame body 10. The predetermined position is determined by the lifting travel of the lifting frame body allowed by the lifting transmission mechanism relative to the main frame body. The second transmission shaft 70 is disposed on the lifting frame body 20, the second rotating wheel 80 is fixedly disposed on the second transmission shaft 70, the specific disposition thereof is similar to the disposition of the first transmission shaft, the second walking driving device 60 is connected to the second transmission shaft 70 and is configured to drive the second transmission shaft 70 to rotate, and the first transmission shaft 40 is not parallel to the second transmission shaft 70. The first walking driving device and the second walking driving device can be electrically connected with an external controller, such as wire connection, Bluetooth connection, network signal connection and the like, so as to realize remote control. It should be noted that the arrangement of the first transmission shaft 40 and the second transmission shaft 70 is matched with the first track and the second track of the shelf, so that the moving direction of the first rotating wheel is consistent with the direction of the first track, and the moving direction of the second rotating wheel is consistent with the direction of the second track.
Through the above, it can be easily found that the present invention realizes the technical effect of integrated lifting and reversing by the mechanical cooperation among the main frame 10, the lifting frame body 20, the first travel driving device 30, the first transmission shaft 40, the first rotating wheel 50, the second travel driving device 60, the second transmission shaft 70, the second rotating wheel 80, the lifting transmission mechanism and the worm motor in the handling device, and the handling device can realize the lifting and reversing functions of the device only by one driving device (worm motor). Specifically, the first travel driving device 30 is connected to the first transmission shaft 40 to rotate the first transmission shaft 40, so that the transportation apparatus can be moved by the rotation of the first rotating wheel 50. The worm motor drives the lifting transmission mechanism, so that the lifting frame body 20 can ascend or descend to a preset position relative to the main frame body 10, and the lifting function is realized. And moreover, the lifting stability is further improved due to the self-locking capacity of the worm and gear. Meanwhile, since the second transmission shaft 70 is disposed on the elevator body 20, the second transmission shaft 70 and the second rotating wheel 80 are lifted together with the elevator body 20, and the second rotating wheel 80 is lifted relative to the first rotating wheel 50. It can be understood that when the second rotating wheel 80 is lower than the first rotating wheel 50, the transporting apparatus can travel through the second rotating wheel 80 by activating the second travel driving device 60, and when the second rotating wheel 80 is higher than the first rotating wheel 50, the transporting apparatus can travel through the first rotating wheel 50 by activating the first travel driving device 30, so that the reversing function is realized.
Fig. 3 is a schematic structural diagram of a lifting transmission mechanism in the first embodiment of the present invention, and fig. 4 is a schematic structural diagram of a lifting mechanism in the first embodiment of the present invention. As shown in fig. 3 and 4, the elevator body 20 of the present embodiment is provided with a guide groove 23, and the guide groove 23 is located inside the elevator body 20. The lifting transmission mechanism comprises: a first rack 91, a second rack 92, a lifting rotating rod 94, a lifting turbine 95 and a lifting gear 93. Wherein, first rack 91 is fixed to be set up in guide way 23, and the one end of second rack 92 is fixed to be set up on body frame 10, and the other end slidable sets up in guide way 23, and lifting gear 93 sets up between first rack 91 and second rack 92, and meshes with first rack 91 and second rack 92 respectively, and lift turbine 95 and lifting gear 93 are fixed respectively to be set up on lift dwang 94 for it is rotatory to drive lifting gear 93. Fig. 5 is a schematic view of an operation state of the lifting mechanism in the first embodiment of the present invention, and fig. 6 is a schematic view of another operation state of the lifting mechanism in the first embodiment of the present invention. As can be seen from fig. 5 and 6, the rotation of the lifting gear can drive the first rack and the second rack to move in the direction, so as to lift the lifting frame body relative to the main frame body. In addition, it should be noted that the worm motor in the process also goes up and down, so in this embodiment, the worm motor is not fixedly disposed on the lifting frame body, but is located in the inner space of the lifting frame body, the inner space not only can accommodate the worm motor, but also can provide a certain lifting space for the worm motor, the worm motor can be connected with the lifting gear through a connecting member, the connecting member can be a straight bar-shaped shaft rod, and the shaft rod has a certain bending resistance so as to meet the requirement that the shaft rod does not bend while bearing the gravity of the worm motor. Preferably, the weight of the drive device is reduced as much as possible to ensure strength.
It should be emphasized that the lifting transmission mechanism adopts the combination of gear rack groups, and the lifting transmission mechanism is simple in structure with the traditional cam transmission, eccentric wheel transmission, lead screw transmission, cylinder transmission and other modes, and because the gear rack transmission is meshing transmission, mechanical parts are small in abrasion and long in service life in the lifting process, and lifting self-locking dead angles (which generally need 180 degrees of rotation of corresponding mechanisms) are not needed to be designed like cam lifting and eccentric wheel lifting mechanisms, the rotation angle (less than 180 degrees) of a motor can be set by self, the concept requirement of the self-locking dead angles is avoided, and therefore the reversing lifting speed is higher. And because the rotation angle of the gear rack group can be set to be less than 180 degrees, the limitation of the 180-degree upper and lower dimension of the cam jacking mechanism and the eccentric wheel jacking mechanism is not needed, and the vehicle body is thinner.
It should be noted that in another embodiment of the present invention, the lifting mechanism may be composed of a lifting gear and a rack. The lifting gear is engaged with the rack to lift and lower the rack. The top of rack can be in lifting support body fixed connection, and the body frame is internal to be fixed and to be set up a axostylus axostyle, and the fixed setting of lifting gear is on this axostylus axostyle, also can realize the lift of the relative body frame body of lifting support body. Compared with the first embodiment, the worm motor in this embodiment may be fixedly disposed on the main frame body.

The second embodiment is an alternative of the first embodiment, and the difference is that in this embodiment, the lifting frame body 20 includes: a driving jacking sliding block 21, a driven jacking sliding block 22 and a jacking platform 24. Specifically, the driving jacking sliding block 21 and the driven jacking sliding block 22 are both provided with a lifting transmission mechanism; the worm motor is connected with a lifting gear 93 on the driving jacking sliding block 21; the driving jacking sliding block 21 and the driven jacking sliding block 22 are both provided with supporting columns 25; a jacking platform 24 is provided on each support column 25. The design makes the carrying equipment of the embodiment bear more uniform stress.

Therefore, in the present embodiment, the worm motor does not ascend and descend.
