Description

Technical Field

[0001] This utility model relates to the field of stacker-reclaimer technology, specifically a gravity self-elevating precision anchoring device for stacker-reclaimers. Background Technology

[0002] Stacker-reclaimers are large-scale bulk material handling equipment commonly found in ports, power plants, steel mills, and other locations that require the handling of large quantities of bulk materials such as coal, ore, and sand. The entire unit is supported by a metal frame and performs both stacking and reclaiming functions through a robotic arm and conveying system. The working process is similar to an enlarged version of the human arm's grasping and placing actions.

[0003] A search revealed a stacker-reclaimer disclosed in Chinese Patent Publication No. CN219031050U, comprising a main body and a cantilever frame. A bucket wheel device is mounted at one end of the cantilever frame. A hinge block is mounted on the main body, and a rotating rod is horizontally mounted on the hinge block, extending through the end of the cantilever frame away from the bucket wheel device. A hydraulic cylinder connects the main body and the cantilever frame; one end of the hydraulic cylinder is hinged to the main body, and the other end is hinged to the cantilever frame. This application helps improve material reclaiming efficiency.

[0004] While the above solutions help improve material handling efficiency, the stacker-reclaimer in the aforementioned patents is difficult to easily add or remove counterweights. When the stacker-reclaimer is affected by uneven ground or load changes, it is prone to overturning or slipping, causing accidents and posing a significant safety hazard. Therefore, we provide a gravity-driven self-elevating precision anchoring device for stacker-reclaimers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a gravity-driven self-elevating precision anchoring device for stacker-reclaimers to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gravity-driven self-elevating precision anchoring device for a stacker-reclaimer, comprising a stacker-reclaimer body, an external counterweight, and an anchoring shell. The inner wall of the anchoring shell is fitted with a protective shell, and a DC motor is mounted on the top of the protective shell. A control linkage disc is mounted on the output shaft of the DC motor. A control cam is mounted in the control slot of the control linkage disc. The control cam is located at the bottom of a positioning slider, which is located at the bottom of an anchoring plate. The tight fit between the components allows for effective and convenient addition or removal of the counterweight.

[0007] Preferably, there are two positioning sliders, which are set in the guide slots opened in the protective shell. The design of the guide slots ensures that the two positioning sliders move stably.

[0008] Preferably, a T-shaped mounting block is provided on one side of the stacker-reclaimer body, and a hydraulic cylinder is provided on the inner wall of the T-shaped mounting block. The hydraulic cylinder is a known technology and will not be described in detail.

[0009] Preferably, there are two hydraulic cylinders, and each of the two hydraulic cylinders has an anchoring shell at one end. The anchoring shell can effectively ensure the stability of the internal components of the anchoring shell.

[0010] Preferably, the external counterweight is positioned directly below the T-shaped mounting block, and the external counterweight has a confining groove. The confining groove facilitates the subsequent lifting of the external counterweight.

[0011] Preferably, the outer circumferential surface of the anchor housing is provided with two insertion holes, which allow the anchor plate to pass through smoothly.

[0012] Preferably, there are two anchor plates, which are set on the top of the protective shell. The anchor plates can be used to control the position of the external counterweight.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] This utility model provides a technical solution for a gravity self-elevating precision anchoring device for a stacker-reclaimer.

[0024] Please see Figure 1 and Figure 2 The stacker-reclaimer includes the stacker-reclaimer body 1, the external counterweight 2, and the anchoring shell 3. The stacker-reclaimer body 1 mainly achieves efficient storage and transfer of materials through automated stacking and reclaiming operations. It consists of components such as bridge, cantilever, foundation counterweight, track-type walking system, rotating platform, wire rope pitching system, and conveyor. It is one of the core equipment for modern industrial bulk material handling. The stacker-reclaimer body 1 is existing known technology, and this application will not elaborate further on the stacker-reclaimer body 1.

[0025] Please see Figure 2 and Figure 3 The outer circumferential surface of the anchor housing 3 is provided with two insertion holes 15. The purpose of setting two insertion holes 15 is to prevent the subsequent anchor plate 10 from being blocked when passing through the anchor housing 3, thereby improving the smoothness of the component movement.

[0026] Please see Figure 1 and Figure 2 The external counterweight 2 is positioned directly below the T-shaped mounting block 12. The reasonable arrangement of the external counterweight 2 and the T-shaped mounting block 12 allows the anchoring shell 3 to smoothly enter the restricted groove 14 without any deviation.

[0027] Please see Figure 1 and Figure 2The external counterweight 2 has a restricted groove 14. The purpose of setting the restricted groove 14 is to facilitate the subsequent installation of the external counterweight 2. A T-shaped mounting block 12 is fixedly connected to one side of the stacker-reclaimer body 1. The purpose of setting the T-shaped mounting block 12 is to effectively provide a reasonable position for the installation of the hydraulic cylinder 13, and to protect the hydraulic cylinder 13 from external interference.

[0028] Please see Figure 2 Two hydraulic cylinders 13 are fixedly connected to the inner wall of the T-shaped mounting block 12. One end of each hydraulic cylinder 13 is fixedly connected to the anchor housing 3. The purpose of setting the hydraulic cylinders 13 is to provide sufficient power support for the vertical lifting of the anchor housing 3. The hydraulic cylinders 13 are existing technology, and this application will not elaborate on the principle, specifications, etc. of the hydraulic cylinders 13.

[0029] Please see Figure 2 and Figure 3 The inner wall of the anchoring shell 3 is fixedly connected to the protective shell 4. The purpose of setting the protective shell 4 is to effectively control the position of the internal components of the protective shell 4 and ensure the stability of the internal components of the protective shell 4 during movement.

[0030] Please see Figure 3 and Figure 4 A DC motor 5 is fixedly connected to the top of the protective shell 4. The output shaft of the DC motor 5 is fixedly connected to the control linkage disk 6. The purpose of setting the DC motor 5 is to effectively provide sufficient power support for the rotation of the control linkage disk 6. The DC motor 5 is existing known technology, and this application will not elaborate on the DC motor 5 further.

[0031] Please see Figure 4 and Figure 5 A control cam 8 is slidably connected in the control slot 7 of the control linkage disk 6. Through the design of the control slot 7, when the control linkage disk 6 rotates, it can drive the restricted control cam 8 to translate. The control cam 8 is rotatably connected to the bottom of the positioning slider 9. The positioning slider 9 will apply a control effect to the control cam 8 to ensure that the control cam 8 can rotate in place and there will be no separation of parts.

[0032] Please see Figure 4 and Figure 5 There are two positioning sliders 9. The two positioning sliders 9 are slidably connected in the guide groove 11 opened in the protective shell 4. Through the design of the guide groove 11, the positioning sliders 9 can be moved in a specified direction within the protective shell 4 without offset or jamming.

[0033] Please see Figure 4 and Figure 5 The positioning slider 9 is fixedly connected to the bottom of the anchor plate 10. The positioning slider 9 and the anchor plate 10 are directly connected and maintain a linkage effect. There are two anchor plates 10 in total. The two anchor plates 10 are set on the top of the protective shell 4. The purpose of setting the anchor plates 10 is that, through the movement of the anchor plates 10, the anchor plates 10 can be inserted into the restricted groove 14 opened in the external counterweight 2, which is conducive to driving the external counterweight 2 to move upward synchronously.

[0034] Working principle: When using the stacker-reclaimer body 1, the hydraulic cylinder 13 can be activated according to the specific conditions of the stacker-reclaimer body 1. The hydraulic cylinder 13 will push the anchoring shell 3 downward, so that the anchoring shell 3 enters the restricted groove 14 opened in the external counterweight 2. Then, the DC motor 5 will be activated, and the DC motor 5 will drive the control linkage plate 6 to rotate in place inside the protective shell 4. At this time, because the positioning slider 9 connected with the control cam 8 will be restricted by the protective shell 4, the control linkage plate 6, through the design of the control through groove 7, can be connected with the control cam 8. The positioning slider 9, which is engaged with the cam 8, moves within the guide slot 11 of the protective housing 4, thereby changing the position of the anchor plate 10 engaged with the positioning slider 9. This causes the anchor plate 10 to gradually extend out of the anchor housing 3 through the insertion hole 15, and then penetrate into the restricted groove 14 of the external counterweight 2, thus completing the control of the external counterweight 2. Finally, the hydraulic cylinder 13 is reset, and the external counterweight 2 will fit against the T-shaped mounting block 12. Under the action of gravity, the counterweight of the stacker-reclaimer body 1 is increased, making the stacker-reclaimer body 1 more stable.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
