Description

Technical Field

[0001] This invention relates to the field of mining loader technology, and more specifically, to a hydraulic support loader device. Background Technology

[0002] With the rapid development of energy extraction, thin coal seams with a mining height of less than 2 meters have become an important part of future coal development. Currently, domestic coal mining still mainly focuses on coal seams with a thickness of more than 3.5 meters, and underground hydraulic support shovel-type transport vehicles are also mainly used in such working faces. In the transportation of hydraulic supports in thin coal seams, due to the key characteristic of thin coal seam mining being the low working space height, the hydraulic supports used are transported at a height of less than 0.8 meters. The shovel-type transport vehicle used to load the hydraulic supports cannot have a shoveling mechanism height greater than 0.75 meters. This is usually accomplished using conventional vehicles, inevitably leading to loading difficulties and limited maneuverability.

[0003] Traditional earthmoving devices typically consist of a swing arm, fork support, fork, and hydraulic cylinders, with each component connected by pins and cylinders. This structure requires four hydraulic cylinders and twelve pins to work together, resulting in a large number of parts, complex structure, and high production costs. Furthermore, because traditional earthmoving devices lack guide components, the hydraulic support may shift during the earthmoving process. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, an embodiment of the present invention provides a hydraulic support shoveling device, including: a frame 10; a mounting bracket 20, one end of which is connected to the frame 10; a shoveling structure 30, which includes a shovel plate portion 31 and a guide member 32 disposed on the shovel plate portion 31, the other end of which is rotatably connected to the mounting bracket 20, the shovel plate portion 31 being used to support a hydraulic support 70, and the guide member 32 being used to guide the top plate of the hydraulic support 70 located on the shovel plate portion 31; and a drive portion 40, one end of which is rotatably connected to the mounting bracket 20, and the other end of which is rotatably connected to the bottom of the shovel plate portion 31, the drive portion 40 driving the shovel plate portion 31 to swing relative to the mounting bracket 20 to shovel up the hydraulic support 70 located on the ground.

[0033] In this design, the guide member 32 is mounted on the shovel plate 31. This provides support and guidance to the top plate of the hydraulic support 70 during transport, preventing it from shifting. Furthermore, the transport structure 30 and the mounting support 20 are rotatably connected. One end of the drive unit 40 is rotatably connected to the mounting support 20, and the other end is rotatably connected to the bottom of the shovel plate 31. This allows the drive unit 40 to drive the shovel plate 31 to swing, thereby scooping up the hydraulic support 70 from the ground. This hydraulic support transport device effectively solves the problem in existing hydraulic support transport devices that cannot guide the hydraulic support 70 during transport.

[0034] The guide member 32 has a guide surface 321, which guides the top plate of the hydraulic support 70 located on the shovel plate 31. Multiple guide members 32 are spaced apart on the shovel plate 31. The guide surface 321 guides the top plate of the hydraulic support 70 on the shovel plate 31, preventing the hydraulic support 70 from shifting during shoveling. Furthermore, by having multiple guide members 32, each can guide the top plate of the hydraulic support 70, further improving the guiding effect.

[0035] like Figure 1As shown, the guide member 32 includes a guide plate 322 and an extension plate 323 connected to each other. The guide plate 322 is connected to the shovel plate portion 31, and the end face of the extension plate 323 and the end face of the guide plate 322 form a guide surface 321. The extension plate 323 is provided to extend the length of the guide surface 321 as much as possible, thus ensuring the guiding effect.

[0036] Specifically, the shovel plate section 31 includes a main shovel plate 311, a shovel plate bracket 312, and a shovel plate connecting frame 313.

The other end of the drive unit 40 is rotatably connected to the bottom of the main shovel plate 311. The drive unit 40 drives the main shovel plate 311 to swing relative to the mounting support 20. The guide member 32 is connected to both the main shovel plate 311 and the shovel plate bracket 312. The main shovel plate 311 is used to support the hydraulic support 70. With this configuration, the drive unit 40 can drive the main shovel plate 311 to swing relative to the mounting support 20, thereby shoveling up the hydraulic support 70 located on the ground. The shovel plate connecting frame 313 is rotatably connected to the mounting support 20.

[0037] The shovel plate bracket 312 includes a first bracket 3121 and a second bracket 3122. The shovel plate connecting frame 313 includes a first connecting frame 3131, a second connecting frame 3132, and a base plate 3133. The two ends of the base plate 3133 are respectively connected to the first connecting frame 3131 and the second connecting frame 3132. One side of the first bracket 3121 is connected to one end of the main shovel plate 311, and the other side of the first bracket 3121 is connected to one end of the first connecting frame 3131. The other end of the first connecting frame 3131 is rotatably connected to one side of the mounting support 20. One side of the second bracket 3122 is connected to the other end of the main shovel plate 311, and the other side of the second bracket 3122 is connected to one end of the second connecting frame 3132. The other end of the second connecting frame 3132 is rotatably connected to the other side of the mounting support 20. The guide member 32 is connected to both the main shovel plate 311 and the first bracket 3121, or the guide member 32 is connected to both the main shovel plate 311 and the second bracket 3122. By adopting the above configuration, the shovel plate bracket 312 and the shovel plate connecting frame 313 can be connected. The guide member 32 can be connected to both the main shovel plate 311 and the first bracket 3121, or the guide member 32 can be connected to both the main shovel plate 311 and the second bracket 3122. In both cases, the guide member 32 can guide the top plate of the hydraulic support 70.

[0038] Optionally, a first clearance opening is provided between the first support 3121 and the second support 3122, and a second clearance opening is provided between the first connecting frame 3131 and the second connecting frame 3132. The first clearance opening and the second clearance opening are connected, and the first clearance opening and the second clearance opening can provide clearance for the top plate of the hydraulic support 70.

[0039] Optionally, the first connecting frame 3131 includes a first frame and a second frame arranged side by side. One end of the first frame and the second frame are both connected to the first bracket 3121. The other ends of the first frame and the second frame are located at the two ends of the mounting bracket 20, respectively, and the other ends of the first frame, the mounting bracket 20, and the second frame are connected in sequence by pins. The second connecting frame 3132 has the same structure as the first connecting frame 3131.

[0040] In this embodiment, the drive unit 40 includes a first tilting cylinder 41 and a second tilting cylinder 42. The hydraulic support 70 shoveling device also includes a first pin 51, a second pin 52, a third pin 53, and a fourth pin 54. The cylinder body of the first tilting cylinder 41 is connected to the mounting bracket 20 via the first pin 51. The telescopic rod of the first tilting cylinder 41 is connected to the bottom of the shovel plate part 31 via the second pin 52. The cylinder body of the second tilting cylinder 42 is connected to the mounting bracket 20 via the third pin 53. The telescopic rod of the second tilting cylinder 42 is connected to the bottom of the shovel plate part 31 via the fourth pin 54. With the above configuration, the shovel plate part 31 can be driven to swing by the first tilting cylinder 41 and the second tilting cylinder 42, thereby shoveling up the hydraulic support 70 located on the ground. In this solution, the swing arm configuration of the existing technology is abandoned, and only the first tilting cylinder 41 and the second tilting cylinder 42 are set. This makes the hydraulic support shoveling device of this solution simple in structure and highly reliable. It also reduces the height of the entire hydraulic support shoveling device, which is beneficial for shoveling hydraulic supports in low and thin coal seams and has a wider range of applications.

[0041] Specifically, the mounting bracket 20 includes a first connecting seat 21 and a second connecting seat 22 connected to each other. The first connecting seat 21 and the second connecting seat 22 are perpendicular to each other. The first connecting seat 21 is connected to the frame 10, the upper end of the second connecting seat 22 is rotatably connected to the shovel plate portion 31, and the lower end of the second connecting seat 22 is rotatably connected to the drive portion 40. In this design, the first connecting seat 21 is fixedly connected to the frame 10 by a positioning pin, the upper end of the second connecting seat 22 is connected to the shovel plate portion 31 by a pin, and the lower end of the second connecting seat 22 is connected to the drive portion 40 by a pin. This connection method facilitates installation and disassembly.

[0042] Furthermore, the end of the first connecting seat 21 away from the second connecting seat 22 has a guide slope 211. The frame 10 includes a first connecting vertical plate 11, a second connecting vertical plate 12, a support plate 13, and a limiting plate 14. The two ends of the support plate 13 are respectively connected to the first connecting vertical plate 11 and the second connecting vertical plate 12. The limiting plate 14 is connected to the support plate 13, the first connecting vertical plate 11, and the second connecting vertical plate 12. The area enclosed by the first connecting vertical plate 11, the second connecting vertical plate 12, the support plate 13, and the limiting plate 14 forms a limiting groove. The first connecting seat 21 is inserted into the limiting groove. The guide slope 211 and the limiting plate 14 are in a limiting fit. The first connecting vertical plate 11 is connected to one side of the first connecting seat 21, and the second connecting vertical plate 12 is connected to the other side of the first connecting seat 21. With the above-mentioned arrangement, the first connecting seat 21 is inserted into the limiting groove, and the guide slope 211 and the limiting plate 14 are in a limiting fit, which facilitates the installation of the frame 10 and the mounting bracket 20.

[0043] The hydraulic support 70 shoveling device also includes a chain guide frame 60 mounted on the shovel plate 31. The support plate 13 has a first through hole 131, the second connecting seat 22 has a second through hole 221, the shovel plate 31 has a third through hole, and the chain guide frame 60 has a fourth through hole 66. The first through hole 131, the second through hole 221, the third through hole, and the fourth through hole 66 are all interconnected. This arrangement allows the chain extending from the frame 10 to pass sequentially through the first through hole 131, the second through hole 221, the third through hole, and the fourth through hole 66, thereby connecting with the hydraulic support 70 and achieving the purpose of pulling the hydraulic support 70. The chain guide frame 60 serves to guide the chain.

[0044] Furthermore, the chain guide frame 60 includes a main body 61 and a first connecting shaft 62, a second connecting shaft 63, a third connecting shaft 64, and a fourth connecting shaft 65 disposed on the main body 61. The main body 61 is connected to the shovel plate portion 31. The first connecting shaft 62 and the second connecting shaft 63 are arranged side by side, and the third connecting shaft 64 and the fourth connecting shaft 65 are arranged side by side. The first connecting shaft 62 and the third connecting shaft 64 are perpendicular to each other. The area enclosed by the first connecting shaft 62, the second connecting shaft 63, the third connecting shaft 64, and the fourth connecting shaft 65 forms a fourth through hole 66. This arrangement allows the fourth through hole 66 to be formed, facilitating the passage of the chain.

[0045] Optionally, sleeves are fitted on the first connecting shaft 62, the second connecting shaft 63, the third connecting shaft 64 and the fourth connecting shaft 65. After the chain contacts the sleeve, the sleeve can rotate with the chain, so that the chain passes through more smoothly.
