The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 and 2, the hoist of the present embodiment includes a frame 10, a lifting platform assembly 20, and a first driving mechanism 30. Wherein, promote platform assembly 20 and rotationally set up on frame 10 on the vertical plane, promote platform assembly 20 and include a plurality of lift platform 21, a plurality of lift platform 21 use the middle part of promoting platform assembly 20 to set up along circumference interval on the vertical plane. A first drive mechanism 30 is disposed between the frame 10 and the lift platform assembly 20, the first drive mechanism 30 being adapted to simultaneously rotate the plurality of lift platforms 21 along the middle of the lift platform assembly 20.

With the technical solution of this embodiment, the lifting platform assembly 20 includes a plurality of lifting platforms 21, and the plurality of lifting platforms 21 are arranged at intervals along the circumferential direction on the vertical plane, so that the lifter can pick up a plurality of die tables (or other components) at different heights and at different stations. The first drive mechanism 30 drives the plurality of lift platforms 21 to rotate, thereby enabling the tables (or other components) to be simultaneously transferred to other stations. The structure greatly improves the circulation efficiency of the hoister, and solves the defect of low circulation efficiency of the hoister in the prior art.

It should be noted that, the above-mentioned "lifting platforms 21 are circumferentially arranged at intervals on a vertical plane", and then along the height direction, the lifting platforms are arranged like ferris wheels. As shown in fig. 5, the above arrangement is such that, among the plurality of lifting platforms 21, some of the lifting platforms 21 are arranged offset in the vertical direction and some of the lifting platforms 21 are arranged offset in the horizontal direction. The above-described structure allows different lifting platforms 21 to be at different heights or different lifting platforms 21 to be on different sides.

It should be noted that the above-mentioned "the first driving mechanism 30 is adapted to rotate the plurality of lifting platforms 21 synchronously in the circumferential direction" means that the first driving mechanism 30 drives the plurality of lifting platforms 21 to move in a manner similar to the rotation of a ferris wheel. The above-described movement may be such that a certain lifting platform 21 is turned between different heights, or a certain lifting platform 21 is turned between different sides.

As shown in fig. 1 and 2, in the present embodiment, the elevator further includes a rotating frame 40, the rotating frame 40 is rotatably connected to the frame 10, and the plurality of lifting platforms 21 are connected to the rotating frame 40. Specifically, the middle portion of the rotating frame 40 is pivotably connected to the frame 10, and the first driving mechanism 30 can drive the rotating frame 40 to rotate about the rotation center of the middle portion thereof. The plurality of lifting platforms 21 are circumferentially connected to the rotating frame 40 at intervals (specifically, connected to the outer edge of the rotating frame 40), so that when the first driving mechanism 30 drives the rotating frame 40 to rotate, the rotating frame 40 can drive the plurality of lifting platforms 21 to synchronously move along the circumferential direction.

As shown in fig. 3 and 5, in the solution of the present embodiment, the rotating frame 40 includes a plurality of frame bodies 41. The first ends of a plurality of support bodies 41 are connected together and form a rotating connection part, the second ends of the plurality of support bodies 41 are arranged at intervals along the circumferential direction, the first driving mechanism 30 is connected with the rotating connection part, the lifting platform 21 is rotatably arranged at the second end of the support body 41, and the plurality of lifting platforms 21 and the plurality of support bodies 41 are arranged in a one-to-one correspondence manner. Specifically, the frame body 41 has a substantially square frame structure, and one ends of the plurality of frame bodies 41 are connected together and connected to the first driving mechanism 30 through a rotating shaft. The second ends of the plurality of frame bodies 41 are radially arranged. When the plurality of carriers 41 rotate, the second ends of the plurality of carriers 41 move in synchronization in the circumferential direction. The lifting platform 21 is connected to the second end of the frame body 41, and the second end of each frame body 41 is connected to one lifting platform 21, that is, the lifting platforms 21 and the frame bodies 41 are correspondingly arranged one by one.

Further, the number of the frame bodies 41 and the arrangement of the rotating frames can be determined according to actual working requirements. Specifically in this embodiment, the rack body 41 is set to be eight, and in the eight rack bodies 41, two rack bodies 41 are located at upper and lower sides, three rack bodies 41 are located at one side, and the other three rack bodies 41 are located at the other side. Accordingly, eight lifting platforms 21 are provided. The structure enables the eight lifting platforms 21 to be divided into five layers and distributed on two sides. Of course, the arrangement of the plurality of frame bodies 41 is not limited to the above-described manner. The number of the frame bodies 41 and the angle formed between the adjacent frame bodies 41 can be adjusted by those skilled in the art according to actual working requirements.

Preferably, the elevator in this embodiment further includes a second driving mechanism, the second driving mechanism is disposed between the frame body 41 and the lifting platform 21, and the second driving mechanism is adapted to maintain the supporting surface of the lifting platform 21 in a horizontal position when the frame body 41 rotates. Specifically, in order to ensure that the mold table (or other components) is always in a horizontal state during the circulation of the lifting platform 21, a second driving mechanism is further provided in the embodiment. The second driving structure enables the lifting platform 21 to rotate correspondingly when the frame body 41 rotates, so that the supporting surface of the lifting platform 21 can be kept horizontal all the time. The second driving structure can be a torsion device, and the lifting platform can be always in a horizontal state through the matching of the torsion device and the horizontal sensor.

As shown in fig. 1 and fig. 2, in the technical solution of the present embodiment, the frame 10 includes a top frame 11 and a guide post 12 disposed on the top frame 11, the rotating frame 40 can slide in the vertical direction along the guide post 12, and the elevator further includes a third driving mechanism, and the third driving mechanism drives the rotating frame 40 to slide along the guide post 12. Specifically, when the rotating frame 40 slides up and down along the direction of the guide post 12, the plurality of lifting platforms 21 can be driven to move up and down synchronously, and the vertical circulation range of the lifting platforms 21 is further increased. The third driving mechanism may be a winch, a driving cylinder, a lead screw and nut mechanism, etc. It will be understood by those skilled in the art that the rotating frame 40 in the present embodiment can move linearly in the vertical direction, and can also move rotationally around its rotation axis.

Of course, in some embodiments, not shown, the third drive mechanism may not be provided on the hoisting machine. In combination with the above description, since the arrangement of the plurality of lifting platforms 21 is misaligned in the vertical direction, when the plurality of lifting platforms 21 rotate synchronously, a vertical circulation within a certain range can be realized. It will be appreciated by those skilled in the art that when the plurality of lifting platforms 21 rotate synchronously, the vertical range of rotation is sufficient to meet the work requirement, and the third driving mechanism may not be provided, that is, the rotating frame 40 is fixedly arranged and only rotates around the rotation axis.

As shown in fig. 2, in the technical solution of this embodiment, a slide rail 121 is disposed on the guide post 12, the elevator further includes a supporting block 50, the supporting block 50 is disposed in the slide rail 121, the third driving mechanism drives the supporting block 50 to slide in the slide rail 121, and the first driving mechanism 30 is disposed on the supporting block 50. Specifically, the number of the guide posts 12 is two, and the two guide posts 12 support the rotating frame 40 from both sides, respectively. The two guide posts 12 are provided with slide rails 121, and the slide rails 121 of the two guide posts 12 are provided with supporting blocks 50. Two ends of the middle rotating shaft of the rotating frame 40 are respectively connected with the two supporting blocks 50, the first driving mechanism 30 is arranged on one of the supporting blocks 50 and connected with the rotating shaft, or the two supporting blocks 50 are both provided with the first driving mechanism 30. Further, the third driving mechanism is a hoisting mechanism, and the hoisting mechanism is connected with the supporting block 50 through a connecting rope. When the hoisting mechanism tightens the connection rope, the supporting block 50 can be driven to slide upwards in the sliding rail 121, so as to drive the rotating frame 40 to move upwards integrally. When the winding mechanism releases the connection rope, the rotating frame 40 moves downward by its own weight, and at this time, the supporting block 50 slides downward in the sliding rail 121.

Since the rotating frame 40 is disposed between the two support blocks 50 and the connection rope of the winding structure is connected to the support blocks 50, the connection rope does not interfere with the rotation of the rotating frame 40. The above structure ensures that the rotary frame 40 can perform linear motion in the vertical direction while performing rotary motion.

Preferably, a sliding structure is provided between the slide rail 121 and the support block 50. The sliding structure may be a pulley, and the sliding structure facilitates the supporting block 50 to slide smoothly in the sliding rail 121.

As shown in fig. 4, in the solution of the present embodiment, a traveling mechanism 60 adapted to be coupled to an external rail is provided on the top frame 11. Specifically, the traveling mechanism 60 described above can circulate the hoist in the horizontal direction, thereby further expanding the circulation range of the hoist. Further, the traveling mechanism 60 includes traveling wheels and motors that drive the traveling wheels to rotate. Of course, it will be understood by those skilled in the art that it is possible to implement the elevator without the traveling mechanism 60 described above if the elevator is only associated with one device.

The above is an embodiment of the hoisting machine of the present application, and an embodiment of the concrete precast element production line of the present application will be described below.

Example one

As shown in fig. 1 and 5 to 7, a concrete prefabricated part production line of the present embodiment includes a production apparatus 100, the production apparatus 100 has a multi-story work space 101, and a hoist is provided outside the production apparatus 100.

Specifically, referring to fig. 5 to 7, the production apparatuses 100 are arranged in two rows, and the elevator is disposed between the two rows of the production apparatuses 100, each row having a plurality of production apparatuses 100 disposed in sequence. In the multi-layer work space 101 of the production apparatus 100, the lowermost work space 101 may be used as a passage layer, and the other work spaces may be used for various jobs. For example, a certain work space 101 is provided as a flushing station, a troweling station, an oiling station, a distributing station, or a vibrating station, etc.

The production device forms a vertical and horizontal three-dimensional multi-station production line, and has the characteristics of small floor area and high space utilization rate. Through the rotation (forward rotation or overturn) and the vertical movement of the rotating frame 40 of the hoist, the hoisting platform 21 can be circulated between different working spaces 101. Since the lifting platform 21 is provided in plurality, a plurality of die tables (or other members) can be circulated at the same time.

Further, the above-mentioned lifting platform 21 can be used for a flow mold table, a flow member, or other production equipment, etc. The die table is provided with a guide wheel and a driving wheel, so that the circulation operation is facilitated.

As shown in fig. 4 and 6, in the solution of the present embodiment, the top of the production apparatus 100 is provided with a rail 102, and the top of the frame 10 is provided with a running mechanism 60 engaged with the rail 102. Specifically, the above structure may allow the hoist to run to different production apparatuses 100 in the lateral direction, thereby increasing the circulation range of the hoist.

Example two

As shown in fig. 8, the concrete precast element manufacturing line according to the second embodiment is different from the first embodiment in that the outer edges of the work tables of the work spaces 101 of the two opposite manufacturing apparatuses 100 are arranged in a circumferential shape. Further, the above-mentioned circumferential shape is determined according to the rotation radius of the rotating frame 40. The above structure can make the engagement between the working space 101 and the lifting platform 21 better.

EXAMPLE III

As shown in fig. 9, the precast concrete unit production line according to the third embodiment is different from the second embodiment in that the hoist is fixedly installed on the ground and the traveling mechanism 60 is not installed on the top of the hoist.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
