Description

Technical Field

[0001] This invention relates to a pile shoe, belonging to the field of mining machinery, and particularly to a heavy-duty, autonomously movable pile shoe. Background Technology

[0002] Currently, the mining process in open-pit mines proceeds continuously along the ore vein. Due to the constant changes in the working site, the applicability of fixed continuous mining technology is relatively low. Most mines adopt a semi-continuous production process of single bucket truck + semi-fixed crushing station, using trucks to transport minerals from the bottom of the mine to the top crushing station. This results in very high mining costs and serious environmental pollution.

[0003] If a process device exists that can transport minerals directly from the bottom to the top of the mine, it would be relatively faster. However, considering the need to improve the applicability of continuous mining technology to suit continuous mining operations, such a process device must be equipped with an autonomous mobile device that can continuously move its working position. This would drive the process device to change its operating position within the mine, thereby ensuring the smooth progress of the continuous mining process. In addition, since the process device is generally quite heavy, it would impose a large load. Therefore, a heavy-duty autonomous mobile device is urgently needed.

[0004] The information disclosed in this background section is intended only to enhance understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

The support body includes a left support leg, a support cross plate, and a right support leg. The top end of the left support leg is perpendicularly connected to the bottom end of one end of the support cross plate, and the bottom end of the other end of the support cross plate is perpendicularly connected to the top end of the right support leg. The left support leg, the support cross plate, and the right support leg together form an internal cavity. A sliding base plate is provided inside the internal cavity, which is directly opposite the support cross plate. A slide rail is provided on the bottom surface of the sliding base plate near its front and rear sides. The bottom surface of the slide rail slides and overlaps with the bottom end of the C-shaped hook.

The portion of the sliding base plate located between the left support leg and the left end of the slide rail is respectively connected to the top of the two transverse push blocks. A transverse groove extending longitudinally is provided on the side of the transverse push block near the left support leg. A transverse slider that slides relative to the groove is provided inside. The middle part of the transverse slider is connected to one end of the output rod of the transverse cylinder. The other end of the output rod passes through the internal cavity and is connected to the transverse cylinder installed in the left support leg. The right side of the left support leg, sandwiched between the two transverse hydraulic cylinders, is connected to the left end of the left longitudinal push block. The left side of the right support leg is connected to the right end of the right longitudinal push block. The right ends of both the left and right longitudinal push blocks extend laterally to the bottom of the sliding base plate.

The width of the transverse push slot is smaller than the width of the transverse push groove.

[0009] The side of the lifting cylinder seat is connected to the bottom of the sliding base plate by multiple seat reinforcing ribs. Among them, the seat reinforcing ribs near the transverse push base are connected to the side of the transverse push base to form a top transverse reinforcing structure. The seat reinforcing ribs near the slide rail extend to be flush with the bottom surface of the slide rail and are connected to form a seat rail reinforcing structure. In the transverse direction, the seat reinforcing ribs on two adjacent lifting cylinder seats are connected to each other to form a seat transverse reinforcing structure.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention relates to a heavy-duty, autonomously movable pile shoe, which mainly includes a support body, a sliding base plate, a C-shaped hook, a lateral movement cylinder, a lateral movement push block, a longitudinal movement cylinder, and a lifting cylinder. The sliding base plate is located between the left and right support legs of the support body. The bottom surface of the sliding base plate and the top surface of the support plate are simultaneously connected to the bottom and top ends of the C-shaped hook (sliding overlap with the sliding base plate and fixed connection with the support plate). The lateral movement push block and the longitudinal movement cylinder are fixedly connected to the bottom surface of the sliding base plate. The lateral movement cylinder is fixedly connected to the left support leg (or, to suit different needs, to the right support leg). The longitudinal movement push block is connected to the inner surfaces of the left and right support legs. At least one lifting cylinder seat is provided in the middle of the sliding base plate, and a lifting cylinder is installed inside the lifting cylinder seat. The output rod of the hydraulic cylinder extends downwards until it connects with the middle of the support chassis. In application, the internal cavity formed by the left support leg, the support cross plate, and the right support leg serves as the operating area. Within this area, the lateral or longitudinal movement of the support body is achieved by switching the contact intervals between the support legs (left and right) and the support chassis with the ground, in conjunction with the driving of the lateral or longitudinal push blocks. Furthermore, multiple movement modes can be implemented, allowing this design to move external equipment connected to the support body to any position, making it particularly suitable for mining applications. In addition, this design can connect to external equipment via the top of the support cross plate. When the support body moves, the external equipment moves along with it, achieving autonomous movement under load. The external equipment is heavy mining machinery suitable for mining operations. Therefore, this invention enables autonomous movement under heavy loads.

[0017] 2. In this invention, a heavy-duty autonomously movable pile shoe, the load is transferred from top to bottom via a support body (preferably with a support column connected to its top) → sliding base plate and its upper components → lifting cylinder seat → lifting cylinder → support chassis. This design not only ensures a clear and smooth load transfer path, but also combines the relative positions of the structures with the placement of reinforcing ribs. For example, the relative positions of the longitudinal and transverse push blocks, the relative positions of the longitudinal and transverse cylinders, and the limitation of their interaction areas with the push blocks are all incorporated. Furthermore, an integrated reinforcing structure based on the lifting cylinder seat, such as a top transverse reinforcing structure, a seat rail reinforcing structure, a seat transverse reinforcing structure, and a seat longitudinal reinforcing structure, maximizes the overall load transfer capability. Based on a compact structural arrangement of multiple components, a good load transfer path is constructed. According to application tests, this design can withstand a load of 1500t. Therefore, this invention not only has a strong load-bearing capacity and can move autonomously under heavy loads, but also high mechanical strength.

[0018] 3. In this invention, a heavy-duty, autonomously movable pile shoe, after moving to a predetermined position, the angle-adjusting hydraulic cylinder drives the support column to rotate around the left and right support seats, changing the relative angle between the support column and the support body. This ensures the support column remains vertical regardless of ground slope, preventing tilting of external equipment (such as process equipment) connected to the support column. Simultaneously, under its own weight and the weight of the external equipment, the bottom of the support body—the left and right support legs—adapts to changes in ground slope, maintaining complete contact with the ground and ensuring rigid support. Therefore, this invention not only provides strong support but also ensures the appropriate positioning of external equipment, guaranteeing smooth mineral processing.

[0019] 4. In this invention, a heavy-duty autonomously movable pile shoe achieves lateral or longitudinal movement of a single pile shoe through the switching operations of various hydraulic cylinders and push blocks, as well as the interval switching of the contact between the support legs (left support leg, right support leg) and the support chassis with the ground. Based on this, by designing a specific connection sequence, step-like movement can be achieved, and multiple work cycles can achieve long-distance movement. Furthermore, assuming an external device is equipped with multiple of these heavy-duty autonomously movable pile shoes, the cooperation of these pile shoes can achieve even richer movement effects. Therefore, this invention not only achieves autonomous movement but also provides superior movement performance. Attached Figure Description

The bottom of the inner ear plate 72 and the outer ear plate 73 are connected to the top surface of the support top plate 28 through the base plate 71. The top of the inner ear plate 72 and the outer ear plate 73 are respectively provided with an inner shaft hole 721 and an outer shaft hole 731. The support column 8 is a cylindrical structure. Inside the support column 8, there is an angle adjustment cylinder 81 and an upper arch arm 82.

The rotating shaft 74 has an arm through hole 831, an inner shaft hole 721, a bushing hole 844, and an outer shaft hole 731 sequentially fitted on its side wall from the inside to the outside. A flat key 75 is sandwiched between the side wall of the rotating shaft 74 and the arm through hole 831 and the inner shaft hole 721.

[0045] The principle of this invention is explained as follows: In this invention, the width of the end (i.e., the inner end) of the left longitudinal push block 6 and the right longitudinal push block 60 connected to the support leg is greater than the width of the other end. In detail, the longitudinal push near cylinder plate 64 and the longitudinal push far cylinder plate 66 are both constructed with the inner end width being greater than the outer end width. Therefore, the width of the longitudinal push reinforcing plate 65 located between the longitudinal push near cylinder plate 64 and the longitudinal push far cylinder plate 66 is different, and even the shape is not completely consistent. However, in terms of function, they can all play the role of reinforcing support.

[0046] In this invention, the slide rail 31 is preferably made of a T-beam. On this basis, an additional sliding sub-rail 311 is constructed on the inner side of the slide rail 31. The sliding sub-rail 311 is located between the lifting cylinder seat 32 and the slide rail 31.

The support body 2 includes a left support leg 21, a support cross plate 22, and a right support leg 23. The top end of the left support leg 21 is perpendicularly connected to the bottom of one end of the support cross plate 22, and the bottom of the other end of the support cross plate 22 is perpendicularly connected to the top end of the right support leg 23. The left support leg 21, the support cross plate 22, and the right support leg 23 together form an internal cavity 24. The sliding base plate 3 is disposed inside the internal cavity 24 and is vertically aligned with the support cross plate 22. The bottom of the sliding base plate 3... A slide rail 31 is provided on the front and rear sides of the surface. The bottom surface of the slide rail 31 slides and overlaps with the bottom end of the C-shaped hook 4. The top end of the C-shaped hook 4 is fixedly connected to the top surface of the supporting horizontal plate 22, and the top of the supporting horizontal plate 22 is connected to external equipment. The part of the sliding base plate 3 between the left support leg 21 and the left end of the slide rail 31 is respectively connected to the top of the two transverse push blocks 5. A transverse groove 51 extending longitudinally is provided on the side of the transverse push block 5 near the left support leg 21. The interior of the transverse groove 51 is provided for relative sliding. The transverse slider 52 has its middle part connected to one end of the output rod of the transverse cylinder 53. The other end of the output rod passes through the internal cavity 24 and is connected to the transverse cylinder 53 installed in the left support leg 21. The part of the right side of the left support leg 21 sandwiched between the two transverse cylinders 53 is connected to the left end of the left longitudinal push block 6. The left side of the right support leg 23 is connected to the right end of the right longitudinal push block 60. The right ends of the left longitudinal push block 6 and the left ends of the right longitudinal push block 60 both extend laterally to the bottom of the sliding base plate 3. The left longitudinal push block 6 and the right longitudinal push block 6... On the same side of 0, there are longitudinally extending grooves 61. The longitudinally extending grooves 61 are provided with longitudinally sliding sliders 62 that slide relative to them. The middle part of the longitudinally extending sliders 62 is connected to one end of the output rod of the longitudinally extending cylinder 63. The other end of the output rod is connected to the longitudinally extending cylinder 63 mounted on the bottom surface of the sliding base plate 3. At least one lifting cylinder seat 32 is provided in the middle of the bottom surface of the sliding base plate 3. The lifting cylinder seat 32 is provided with a lifting cylinder 33.

[0050] In application, first, the left support leg 21 and right support leg 23 are brought into contact with the ground 1, and the support chassis 34 is suspended in the air. Then, the transverse movement cylinder 53 drives the transverse movement push block 5 to move to the right via its output rod. The transverse movement push block 5 drives the support chassis 34 to move to the right via the sliding base plate 3. The C-shaped hook 4 realizes the relative sliding between the sliding base plate 3 and the support cross plate 22. Then, when the support chassis 34 moves to the right to the set position, the lifting cylinder 33 drives the support chassis 34 to move downward to contact the ground 1, and lifts the left support leg 21 and right support leg 23 to lift them off the ground 1. Then, the operation... The horizontal movement cylinder 53 retracts the output rod to pull the left support leg 21 to the right. At the same time, the left support leg 21 acts on the sliding base plate 3 through the support plate 22, C-shaped hook 4, and slide rail 31 in sequence to shorten the distance between the left support leg 21 and the sliding base plate 3. After the left support leg 21 moves to the right to the set position, the lifting cylinder 33 is operated to drive the support chassis 34 to move upward, so that the left support leg 21 and the right support leg 23 contact the ground 1, and the support chassis 34 is suspended in the air. ... This operation is repeated until the entire support body 2 moves laterally to the set position.

[0051] Furthermore, the longitudinal and lateral movements of the support 2 are similar, with the only difference being the operation combination of "longitudinal cylinder 63, left longitudinal push block 6, right longitudinal push block 60" and the operation combination of "lateral cylinder 53, lateral push block 5".
