Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to a bidirectional tilting hoisting structure. Background Technology

[0002] A hoist is a device that lifts a bucket to a designated position on the equipment. It typically includes a support frame, a hydraulic lifting device, and a lifting seat. The hydraulic lifting device is located at the bottom of the support frame, and the lifting seat moves vertically along the support frame and is lifted and lowered under the drive of the hydraulic lifting device. A support platform for supporting the bucket is provided on one side of the lifting seat.

[0003] Existing support platforms are generally vertical. When the hopper reaches the required height and needs to dock with the other side of the equipment's feeding position, a tilting component located between the support platform and the lifting seat flips the support platform to achieve docking. However, most existing tilting components are unidirectional, only capable of tilting in one direction, resulting in low flexibility and inefficiency when docking from both sides is required. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a bidirectional tilting and lifting machine structure.

[0005] The technical solution adopted by this utility model is as follows: A bidirectional tilting and lifting machine structure includes a support frame, a hydraulic lifting assembly, and a lifting seat. The hydraulic lifting assembly is disposed at the bottom of the support frame. The lifting seat moves vertically on the support frame under the drive of the hydraulic lifting assembly. A support plate is disposed on one side of the lifting seat, which is linked to the lifting and lifting of the lifting plate and supports the hopper. The support plate moves vertically on the support frame with the lifting seat and has a first discharge height.

[0006] The bracket has a first pair of interfaces and a second pair of interfaces on both sides in the X direction.

[0007] The support plate is connected to a first drive assembly and a second drive assembly at its two ends or near its two ends in the X direction, respectively. The drive shafts of the first drive assembly and the second drive assembly both extend in the Y direction or in the opposite direction.

[0008] When the support is at the first feeding height, the first drive assembly / second drive assembly drives the support plate and hopper to rotate in reverse / forward around their drive shaft to feed material from the first pair of interfaces / second pair of interfaces.

[0009] Preferably, the lower end of the support plate is provided with a first fixing block and a second fixing block, and the first fixing block and the second fixing block are respectively provided with a first positioning cam coaxial with the drive shaft of the first drive assembly and a second positioning cam coaxial with the drive shaft of the second drive assembly on the side of the first fixing block and the side of the second fixing block away from the lifting seat.

[0010] The lifting seat is fixed with a bidirectional cylinder located on the same side as the support plate and arranged along the X direction. The two output ends of the bidirectional cylinder are respectively fixed with a first moving block that cooperates with a first positioning cam and a second moving block that cooperates with a second positioning cam.

[0011] The bidirectional cylinder drives the first positioning cam / second positioning cam to move along the X direction and its opposite direction through the movement of the first moving block / second moving block, thereby pushing the support plate to the first unloading position corresponding to the first pair of interfaces or the second unloading position corresponding to the second pair of interfaces.

[0012] Preferably, the lifting seat is provided with a first stop block and a second stop block on both sides of the bidirectional cylinder.

[0013] When the support plate moves to the first unloading position, the first positioning cam abuts against the first stop block. When the support plate moves to the second unloading position, the second positioning cam abuts against the second stop block.

[0014] Preferably, the first moving block is provided with a first moving semicircular groove, and the second moving block is provided with a second moving semicircular groove.

[0015] The first stop block is provided with a first semi-circular groove, and the second stop block is provided with a second semi-circular groove.

[0016] When the support plate moves to the first unloading position, the first moving block and the first stopping block abut against each other, and the first moving semicircular groove and the first stopping semicircular groove are connected to form a first limiting groove that matches the shape of the first positioning convex shaft and forms a circumferential limiting groove thereon.

[0017] When the support plate moves to the second unloading position, the second moving block and the second positioning stop block abut against each other, and the second moving semicircular groove and the second positioning semicircular groove are connected to form a second limiting circular groove that is adapted to the shape of the second positioning convex shaft and forms a radial limit thereto.

[0018] Preferably, a first flipping shaft and a second flipping shaft are fixed at both ends of the support plate in the X direction, respectively. The first flipping shaft and the second flipping shaft extend along the Y direction and the opposite direction, and at least one end of the first flipping shaft extends out of the support plate to form a first limiting end and a second limiting end.

[0019] The support plate moves vertically on the bracket along with the lifting seat and has a first unloading height position. At the first unloading height position, the bracket has a first flipping limiting block and a second flipping limiting block on both sides of the support plate. The first flipping limiting block and the second flipping limiting block have a first limiting groove and a second limiting groove that cooperate with the corresponding side limiting end and can accommodate the rotation path of the corresponding side limiting end.

[0020] When the support plate is in the first unloading position, the first limiting end is connected to the first limiting groove, and the second limiting end is disengaged from the second limiting groove.

[0021] When the support plate is in the second unloading position, the first limiting end is disengaged from the first limiting groove, and the second limiting end is connected to the second limiting groove.

[0022] Preferably, the hopper has a first conical opening that cooperates with the first pair of interfaces for discharging material and a second conical opening that cooperates with the second pair of interfaces for discharging material.

[0023] Preferably, the hopper is fixed to the support plate by bolts at the bottom.

[0024] The beneficial effects of this utility model are as follows: by setting the first driving component / second driving component to drive the support plate and the hopper to rotate in reverse / forward around its driving shaft to discharge material from the first pair of interfaces / second pair of interfaces, the two sides of the hopper are flipped, which meets the docking requirements of the two sides of the hopper and has high flipping flexibility.

Detailed Implementation

[0037] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0038] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0039] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0040] like Figures 1 to 10As shown in the figure, a bidirectional tilting and lifting machine structure according to an embodiment of the present invention includes a support frame 1, a hydraulic lifting assembly, and a lifting seat 2. The hydraulic lifting assembly is disposed at the bottom of the support frame 1. The lifting seat 2 moves vertically on the support frame 1 under the drive of the hydraulic lifting assembly. A support plate 4 is disposed on one side of the lifting seat 2, which is linked to its lifting and supports the hopper 3. The support plate 4 moves vertically on the support frame 1 with the lifting seat 2 and has a first discharge height.

[0041] The bracket is provided with a first pair of interfaces 101 and a second pair of interfaces 102 on both sides in the X direction.

[0042] The support plate is connected to a first drive assembly and a second drive assembly at its two ends or near its two ends in the 4X direction, respectively. The drive shafts of the first drive assembly and the second drive assembly both extend in the Y direction or in the opposite direction.

[0043] When the bracket 1 is at the first feeding height, the first drive assembly / second drive assembly drives the support plate 4 and the hopper to rotate in reverse / forward around their drive shaft to feed material from the first pair of interfaces 101 / second pair of interfaces 102.

[0044] This design allows the support plate to be flipped on both sides, meeting the requirements for docking on both sides, and offering high flexibility in flipping. The first drive assembly and the second drive assembly are drive components capable of driving the support plate to rotate, specifically rotary motors, which are not shown in the attached diagram.

[0045] The lower end of the support plate 4 is provided with a first fixing block 43 and a second fixing block 44. The first fixing block 43 and the second fixing block 44 are respectively provided with a first positioning cam 431 coaxial with the drive shaft of the first drive assembly and a second positioning cam 441 coaxial with the drive shaft of the second drive assembly on the side away from the lifting seat 2.

[0046] The lifting seat 2 is fixed with a bidirectional cylinder 21 located on the same side as the support plate 4 and arranged along the X direction. The two output ends of the bidirectional cylinder 21 are respectively fixed with a first moving block 211 that cooperates with the first positioning cam 431 and a second moving block 212 that cooperates with the second positioning cam 441.

[0047] The bidirectional cylinder 21 drives the first positioning cam 431 / second positioning cam 441 to move along the X direction and its opposite direction by moving the first moving block 211 / second moving block 212, thereby pushing the support plate 4 to move to the first unloading position corresponding to the first interface 101 or the second unloading position corresponding to the second interface 102.

[0048] This configuration allows the bidirectional cylinder to move the support plate, simplifying the structure, ensuring stable transmission, and providing accurate positioning.

[0049] The lifting seat 2 is provided with a first stop block 23 and a second stop block 24 on both sides of the bidirectional cylinder 21.

[0050] When the support plate 4 moves to the first unloading position, the first positioning cam 431 abuts against the first stop block 23. When the support plate 4 moves to the second unloading position, the second positioning cam 441 abuts against the second stop block 24.

[0051] This setting prevents excessive movement of the bidirectional cylinder, further improving the accuracy of the support plate's positioning.

[0052] The first moving block 211 is provided with a first moving semicircular groove 2111, and the second moving block 212 is provided with a second moving semicircular groove 2121.

[0053] The first stop block 23 is provided with a first stop semicircular groove 231, and the second stop block 24 is provided with a second stop semicircular groove 241.

[0054] When the support plate 4 moves to the first unloading position, the first moving block 211 and the first stopping block 23 abut against each other, and the first moving semicircular groove 2111 and the first stopping semicircular groove 231 connect to form a first limiting groove that matches the shape of the first positioning convex shaft 431 and forms a circumferential limiting groove thereon.

[0055] When the support plate 4 moves to the second unloading position, the second moving block 212 and the second positioning stop block 24 abut against each other, and the second moving semicircular groove 2121 and the second positioning semicircular groove 241 are connected to form a second limiting circular groove that is adapted to the shape of the second positioning convex shaft 441 and forms a radial limit thereto.

[0056] This design enhances the radial limiting effect of the first and second limiting grooves on the first and second positioning convex shafts, ensuring that the support plate rotates around the rotation axis without deviating.

[0057] A first flipping shaft 41 and a second flipping shaft 42 are fixed at both ends of the support plate 4X in the X direction, respectively. The first flipping shaft 41 and the second flipping shaft 42 extend along the Y direction and the opposite direction, and at least one end of them protrudes from the support plate 4 to form a first limiting end 411 and a second limiting end 421.

[0058] The support plate 4 moves vertically on the bracket 1 along with the lifting seat 2 and has a first unloading height position. At the first unloading height position, the bracket 1 is provided with a first flipping limiting block 11 and a second flipping limiting block 12 on both sides of the support plate 4. The first flipping limiting block 11 and the second flipping limiting block 12 have a first limiting groove 111 and a second limiting groove 121 that cooperate with the corresponding side limiting end and can accommodate the rotation path of the corresponding side limiting end.

[0059] When the support plate 4 is in the first unloading position, the first limiting end 411 is connected to the first limiting groove 111, and the second limiting end 421 is disengaged from the second limiting groove 121.

[0060] When the support plate 4 is in the second unloading position, the first limiting end 411 is disengaged from the first limiting groove 111, and the second limiting end 421 is connected to the second limiting groove 121.

[0061] This setting ensures the stability of the support plate during forward and reverse rotation.

[0062] The hopper 3 has a first conical opening 31 that cooperates with the first interface 101 for discharging material and a second conical opening 32 that cooperates with the second interface 102 for discharging material.

[0063] This setting improves the convenience of material feeding from both sides, eliminating the need to adjust the position of the cone.

[0064] The hopper 3 is fixed to the support plate 4 by bolts at the bottom.

[0065] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
