DETAILED DESCRIPTION

[0044] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort fall within the protection scope of the present application.

[0045] A stacker-reclaimer generally consists of a cantilever (scraper) that can pitch and rotate horizontally, a frame, a driving mechanism, and the like. When taking materials, the scraper takes materials and sends them out through the cantilever, and when stacking materials, the materials transported by the main conveyor are thrown to the stockyard through the stacking arm. Large stacker-reclaimers also use counterweight mechanisms to balance the center of gravity during cantilever movement.

[0046] In the related art, the stacker-reclaimer connects the counterweight mechanism and the cantilever through a steel cable. The fixed counterweight mechanism balances the center of gravity of the cantilever during the luffing process. However, the center of gravity of the cantilever changes constantly during the luffing process, and the counterweight mechanism cannot follow the action of the cantilever to adjust the position of the center of gravity in time. Therefore, the overall center of gravity of the stacker-reclaimer also changes, and a large overturning moment is generated. The overturning moment is transmitted from the frame supporting the cantilever and the counterweight mechanism to the foundation, so that the frame and the foundation need to bear a large vertical load, and the structure of the frame is required to be high.

[0047] Embodiments of the present application aim to solve the problem that the cantilever brings a large load to the frame during the luffing process. A counterweight mechanism that reversely swings to adapt to the luffing of the cantilever is provided, so that the counterweight mechanism can automatically balance the overturning moment of the cantilever in real time. The overall center of gravity of the stacker-reclaimer is basically unchanged, and the load borne by the frame is greatly reduced, so that the structure of the frame is required to be low.

[0048] The embodiments of the present application will be described below in conjunction with Figures 1 to 2

[0049] According to the embodiments of the present application, on the one hand, a self-adaptive counterweight cantilever device is provided, which comprises a frame 1, a cantilever 2, a hoisting mechanism, a counterweight mechanism and a counterweight adaptive mechanism. The cantilever 2 is installed on one side of the frame 1. The hoisting mechanism is connected to the cantilever 2 and serves as a driving mechanism for driving the cantilever 2 to luff. The counterweight mechanism is rotatably connected to the end of the frame 1 away from the cantilever 2. The counterweight adaptive mechanism is connected to the cantilever 2 and the counterweight mechanism and is used to drive the counterweight mechanism to swing with the cantilever 2 luffing. The swinging direction of the counterweight mechanism is opposite to the luffing direction of the cantilever 2.

[0050] In the embodiments, the counterweight adaptive mechanism connects the cantilever 2 and the counterweight mechanism, so that the counterweight mechanism can act with the cantilever 2 luffing, and the swinging direction of the counterweight mechanism is opposite to the luffing direction of the cantilever 2. Therefore, the load generated by the cantilever 2 can be balanced to the greatest extent under various working conditions of the luffing operation of the cantilever 2. The overall center of gravity of the self-adaptive counterweight cantilever device is basically unchanged, the stress of the frame 1 is more uniform, the load borne by the frame 1 is greatly reduced, and the structure of the frame 1 is required to be low. Therefore, the overall structure of the self-adaptive counterweight cantilever device is optimized, the total weight is reduced, the operation is more stable, the use cost is reduced. In addition, the movable counterweight mechanism can also bear part of the load of the cantilever 2 during the luffing operation, the moment requirement of the luffing of the cantilever 2 is reduced, and the use power requirement of the hoisting mechanism providing power for the cantilever 2 is also reduced.

[0051] ​Specifically, the bottom of the frame 1 forms a plate-shaped mounting base 101. One end of the cantilever 2 is rotatably connected to the bottom side of the mounting base 101, and the other end of the cantilever 2 is suspended and can rotate horizontally to transport materials, thereby achieving work. The rotatable connection is preferably connected by a rotating shaft, and other conventional rotatable mounting methods can also be selected as needed. One end of the cantilever 2 can move up and down in the pitch direction as shown by arrow B in FIG. 6, and the other end of the cantilever 2 is rotatably connected to the mounting base 101. Figure 1 The counterweight mechanism is rotatably connected to the top of the frame 1 away from the cantilever 2, and can swing around the top of the frame 1 away from the cantilever 2, thereby balancing the overturning moment brought by the pitch of the cantilever 2, and the swing direction of the counterweight mechanism is shown by arrow C in FIG. 7. That is, the cantilever 2 and the counterweight mechanism are arranged in the up and down positions on both sides of the frame 1. The rotatable connection is preferably connected by a pin shaft 603, and other conventional connection methods can also be selected as needed. Figure 1

[0052] When the hoisting mechanism drives the cantilever 2 to pitch up, the counterweight self-adapting mechanism drives the counterweight mechanism to swing down under the gravity of the cantilever 2 and the counterweight mechanism itself. Conversely, when the hoisting mechanism drives the cantilever 2 to pitch down, the counterweight self-adapting mechanism can drive the counterweight mechanism to swing up. Therefore, in the pitch process of the cantilever 2, the center of gravity of the counterweight mechanism also moves, which can balance more than 95% of the gravity moment of the cantilever 2, so that the overall center of gravity of the adaptive counterweight cantilever device remains basically unchanged, greatly reducing the load bearing of the frame 1 and the foundation. At the same time, the counterweight mechanism can at least bear two-thirds of the load of the cantilever 2, thereby reducing the power of the hoisting mechanism to one-third of the traditional hoisting mechanism, greatly reducing the power requirement of the hoisting mechanism.

[0053] ​In one embodiment, the hoisting mechanism comprises: a first traction rope 301, a winding drum 302, and a first pulley assembly. The winding drum 302 is fixedly installed on the top of the mounting seat 101, near one side of the cantilever 2. The fixed installation can be selected from conventional fixed installation methods such as welding, screw bolt connection, etc. The first pulley assembly comprises a first pulley set 303 and a second pulley set 304. The first pulley set 303 is fixedly installed on the frame 1 near one side of the cantilever 2, and the second pulley set 304 is fixedly installed on the cantilever 2 away from the frame 1. The first traction rope 301 is sequentially connected to the winding drum 302, the first pulley set 303, and the second pulley set 304, and is connected to the first pulley set 303 at the second pulley set 304. A first fixed end for fixing the end of the first traction rope 301 is arranged at the first pulley set 303, and the first traction rope 301 is finally fixed at the first fixed end. The first fixed end can be used to fix the first traction rope 301 in a conventional manner. By reversing the winding drum 302, the first traction rope 301 is wound or unwound from the winding drum 302, achieving the up-and-down pitching movement of the cantilever 2. The structure is simple, the first traction rope 301 pulls the cantilever 2 throughout the process, and the cantilever 2 can be prevented from landing abnormally to injure or damage personnel and equipment, thereby improving the safety of the cantilever 2.

[0054] Preferably, the cantilever 2 is a scraper. The first traction rope 301 is a steel wire rope. Of course, other conventional traction ropes can also be selected as needed. The first pulley set 303 is a fixed pulley set formed by four fixed pulleys. The second pulley set 304 is a movable pulley set formed by four movable pulleys, which can pitch with the cantilever 2. The four fixed pulleys and the four movable pulleys are arranged in parallel. Correspondingly, the first traction rope 301 is alternately connected to the four fixed pulleys and the four movable pulleys.

[0055] It should be noted that the movable pulley refers to a pulley that can change position relative to the fixed pulley during operation, and the number of movable pulleys and fixed pulleys and the specific arrangement can be selected as needed. In order to enable the first pulley set 303 and the second pulley set 304 to support the first traction rope 301, it is necessary to alternately connect the four movable pulleys and the four fixed pulleys in the first pulley set 303 and the second pulley set 304, and to set the up-and-down position of the first traction rope 301 connecting the first pulley set 303 and the second pulley set 304 as needed. For example, the first traction rope 301 is first connected to the first fixed pulley, then connected to the first movable pulley, then connected to the second fixed pulley, and then connected to the second movable pulley, and so on.

[0056] In one embodiment, the top of the frame 1 extends horizontally away from the boom 2, forming a connecting frame 102. The counterweight adaptive mechanism includes a second traction rope 401 and a second pulley assembly. The second traction rope 401 is preferably a steel wire rope. The second pulley assembly includes a balance beam 402, a third pulley block 403, a fourth pulley block 404, and a fifth pulley block 405. The balance beam 402 is fixedly mounted on the boom 2 away from the frame 1, capable of pitching and swinging with the boom 2. It is used to secure one end of the second traction rope 401. The third pulley block 403 is fixedly mounted on the top of the frame 1 near the boom 2. The fourth pulley block 404 is fixedly mounted on the connecting frame 102 away from the boom 2. The fifth pulley block 405 is fixedly mounted on the counterweight mechanism and capable of swinging with the counterweight mechanism. The second traction rope 401 is sequentially connected to the balance beam 402, the third pulley block 403, the fourth pulley block 404, and the fifth pulley block 405. The fifth pulley block 405 then turns and is fixed to the connecting frame 102. The connecting frame 102 is provided with a second fixed end for fixing the second traction rope 401 .

[0057] The counterweight adaptive mechanism adopts a second traction rope 401 and a second pulley assembly. Under the action of the pitching movement of the cantilever 2 and the gravity of the counterweight mechanism itself, it can drive the counterweight mechanism to swing with the pitch of the cantilever 2. It has a simple structure, does not require an additional power source, has low operating costs, and is easy to promote.

[0058] In one embodiment, two sets of adaptive counterweight mechanisms are provided, symmetrically mounted on either side of the counterweight mechanism. This balances the forces acting on the counterweight mechanism, improving the load-bearing capacity and safety of the counterweight mechanism. In some embodiments, the number of adaptive counterweight mechanisms can be greater than two, and can be arranged in other configurations as needed.

[0059] It should be noted that the second pulley set 304 and the balance beam 402 are both installed at the cantilever 2 away from the frame 1, so they need to avoid each other to prevent the first traction rope 301 and the second traction rope 401 from interfering with each other.

[0060] Preferably, if Figure 2 As shown. A first pulley mounting frame 103 is provided at the top of the frame 1, near the cantilever 2. The first pulley block 303 is located in the middle of the first pulley mounting frame 103, and two sets of third pulley blocks 403 are located on either side of the first pulley mounting frame 103. Two sets of fifth pulley blocks 405 are fixedly mounted on either side of the counterweight mechanism. A second pulley mounting frame 201 is provided at a position of the cantilever 2 away from the frame 1. The second pulley block 304 is located in the middle of the second pulley mounting frame 201, and two sets of balance beams 402 are located on either side of the second pulley mounting frame 201. Of course, the second pulley block 304 and balance beam 402 can also be installed at other locations on the cantilever 2 as needed.

[0061] In one embodiment, each set of counterweight adaptive mechanism is provided with two second traction ropes 401, so that even if one of the second traction ropes 401 is accidentally disconnected, the other one can still be used to continue to meet the use requirements of the counterweight adaptive mechanism, thereby improving stability and reducing the safety risks that may be caused by accidental disconnection of the second traction ropes 401. In some embodiments, each set of counterweight adaptive mechanism can be provided with more than two second traction ropes 401 according to actual needs to improve the safety and stability of use.

[0062] In one embodiment, the fifth pulley set 405 is a set of movable pulleys formed by two groups of movable pulleys. The two groups of movable pulleys correspond to the two second traction ropes 401 described above, respectively. The third pulley set 403 and the fourth pulley set 404 are both sets of fixed pulleys formed by two groups of fixed pulleys, which can change the movement direction of the second traction ropes 401. It should be noted that the movable pulleys mentioned above refer to pulleys that can change position relative to the fixed pulleys during operation, and the number of groups and the specific arrangement of the movable pulleys and the fixed pulleys can be selected according to actual needs.

[0063] In one embodiment, the adaptive counterweight cantilever device further comprises a support frame 5. The support frame 5 is installed between the connecting frame 102 and the bottom of the frame 1. Specifically, one end of the support frame 5 is fixedly installed on the connecting frame 102 away from one end of the cantilever 2, and the other end of the support frame 5 is fixedly installed on the side of the mounting seat 101 away from the cantilever 2. The support frame 5 forms a triangular structure relative to the frame 1. The connecting frame 102 is supported by the support frame 5 to improve the load capacity of the connecting frame 102. In some embodiments, multiple support frames 5 can be provided to form multiple triangular structures to improve the stability of the support frame 5. Of course, other structures of the support frame 5 can also be selected according to needs, which will not be listed one by one here.

[0064] In one embodiment, the counterweight mechanism includes a counterweight arm frame 601 and a counterweight 602. One end of the counterweight arm frame 601 is rotatably connected to the frame 1 away from the cantilever 2 through a pin shaft 603, which is simple in structure and convenient to install and use. The other end of the counterweight arm frame 601 is fixedly connected to the counterweight 602. When the cantilever 2 is raised by the hoisting mechanism, the counterweight adaptive mechanism rotates downward around the pin shaft 603 with the counterweight arm frame 601, and the position of the counterweight 602 descends. Conversely, when the cantilever 2 is lowered by the hoisting mechanism, the counterweight adaptive mechanism rotates upward around the pin shaft 603 with the counterweight arm frame 601, and the position of the counterweight 602 ascends. The length of the counterweight arm frame 601 needs to be calculated according to the overturning moment generated by the cantilever 2 to maximize the balance of the stress of the frame 1. The counterweight arm frame 601 and the counterweight 602 form a swing arm structure, and the swing range of the counterweight 602 is improved by the counterweight arm frame 601, thereby adapting to the tilting operation of different types of cantilevers 2.

[0065] In one embodiment, the counterweight arm frame 601 is located inside the frame 1. The counterweight 602 is located inside the counterweight arm frame 601, which can avoid the mutual interference of the counterweight arm frame 601, the counterweight 602 and the frame 1 due to relative movement. It should be noted that since the second traction rope 401 and the second pulley assembly are used to connect the cantilever 2 and the counterweight mechanism through the frame 1, the second traction rope 401 needs to be set to avoid interference with other devices in the adaptive counterweight cantilever device according to the actual situation. For the sake of brevity, the specific arrangement of other devices in the adaptive counterweight cantilever device will not be described in detail here.

[0066] To realize the basic functions of the adaptive counterweight cantilever device, the adaptive counterweight cantilever device in the embodiment can also include other necessary modules or components, such as control circuits, wires, etc. It should be noted that the adaptive counterweight cantilever device can include any suitable existing structure of other necessary modules or components. To clearly and simply illustrate the technical solutions provided in the embodiment, the above-mentioned parts will not be described in detail, and the accompanying drawings are also simplified accordingly. However, it should be understood that the present application is not limited in scope by this.

[0067] According to the embodiment of the present application, in another aspect, a stacker-reclaimer is also provided, which includes the adaptive counterweight cantilever device described above. Since the stacker-reclaimer includes the adaptive counterweight cantilever device, it has the same effect as the adaptive counterweight cantilever device, which will not be described here.

[0068] Although the embodiments of the present application are described in conjunction with the accompanying drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
