Description

Technical Field

[0001] This utility model relates to the field of side protection plates, and more particularly to side protection plates for high-strength hydraulic supports. Background Technology

[0002] Hydraulic support side guards are one of the key components of hydraulic supports in fully mechanized coal mining faces. They mainly form a physical barrier by closely adhering to the coal face to prevent coal blocks and gravel from collapsing and injuring people due to pressure or vibration, thus ensuring the safety of coal mining operations.

[0003] The existing support plate lacks the function of stress distribution. Because it lacks the function of stress distribution, stress may concentrate on the root of the connecting lug. After long-term use, the weld may crack and the connecting lug may deform because the welding strength limit at the root of the connecting lug is reached.

[0004] Therefore, in view of the problem that the existing support side plate lacks the function of stress distribution and the stress is concentrated on the root of the connecting lug, resulting in weld cracking and deformation of the connecting lug seat, there is an urgent need to design a new type of high-strength hydraulic support side plate. Utility Model Content

[0005] To overcome the problem that the existing support plate lacks the function of distributing stress, causing stress to concentrate on the root of the connecting lug, resulting in weld cracking and deformation of the connecting lug seat.

[0006] The technical solution of this utility model is as follows: a high-strength hydraulic support side plate, including a base plate; it also includes a mounting seat, a first support plate, a mounting groove, a first connecting plate, a first mounting hole, and a second mounting hole. Mounting seats are provided on both the left and right sides of the upper surface of the base plate. A first support plate is provided on the rear side of the opposite back of the two mounting seats. A mounting groove is provided on the rear surface of the two first support plates on the side away from the mounting seat. A first connecting plate is connected to the rear surface of the two first support plates through the mounting groove. A first mounting hole is provided in the middle of the side of the two first connecting plates away from the mounting seat. A second mounting hole is provided on the rear side of the side of the two first connecting plates away from the mounting seat.

[0007] Preferably, by setting a connecting plate, which forms a connecting ear structure by opening mounting holes one and two, the original connecting ear can be connected and installed, and the stress on the original connecting ear during connection is distributed. This avoids the original connecting ear from breaking during use, thus solving the problem that the existing support side plate lacks the function of distributing stress. Without the function of distributing stress, stress may concentrate on the root of the connecting ear, resulting in weld cracking and deformation of the connecting ear seat.

[0008] Preferably, a support plate 2 is provided on the rear side of each of the two mounting bases, and the rear side of each support plate 2 is connected to the side of its corresponding connecting plate 1 near the mounting base.

[0009] Preferably, both mounting bases have mounting plates on their rear surfaces, and large connecting lugs are installed on the side of the rear surfaces of both mounting plates closest to the connecting plate.

[0010] Preferably, small connecting ears are provided on the rear surface of both mounting plates away from the connecting plate, and the small connecting ears are connected to the mounting plates by welding.

[0011] Preferably, a support plate is provided at the middle position of the upper surface of each of the two mounting bases, and the right surface of each support plate is provided with symmetrical mounting holes.

[0012] Preferably, a connecting plate 2 is provided at the middle position of the upper surface of the base plate, and a mounting hole 4 is provided on the left surface of the connecting plate 2.

[0013] Preferably, the upper surface of the two mounting bases is provided with a connecting groove on the front side, and the upper surface of the base plate is provided with a mounting hole five on the lower side of the two connecting grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a connecting plate, which forms a connecting ear structure through mounting holes one and two, a collaborative load-bearing system is formed with the original connecting ear while maintaining the original connecting ear's installation function. This avoids the original connecting ear from breaking during use and solves the problem that the existing support side plate lacks stress distribution function. Without stress distribution function, stress may concentrate on the root of the connecting ear, leading to weld cracking and deformation of the connecting ear seat. Attached Figure Description

Support plates 3 are provided on the rear sides of the opposite sides of the two mounting bases 2. Mounting grooves 4 are provided on the rear surfaces of the two support plates 3 away from the mounting bases 2. Connecting plates 5 are connected to the rear surfaces of the two support plates 3 through the mounting grooves 4. Mounting holes 6 are provided in the middle of the side of the two connecting plates 5 away from the mounting bases 2. Mounting holes 7 are provided on the rear sides of the side of the two connecting plates 5 away from the mounting bases 2. By providing the connecting plate 5, and by providing mounting holes 6 and 7, a connecting lug structure is formed, which can assist the original connecting lug in connection and installation, distributing the stress on the original connecting lug during connection, thereby preventing the original connecting lug from breaking during use.

[0023] Please see Figures 1-3 In this embodiment, support plates 2 and 8 are provided on the rear sides of the two mounting bases 2. The rear sides of the two support plates 2 and 8 are connected to the side of their corresponding connecting plates 1 and 5 near the mounting base 2. By providing support plates 2 and 8, the connecting plates 1 and 5 are further fixed from the side, thereby strengthening the installation strength of the connecting plates 1 and 5, and making the connecting plates 1 and 5 more stable during use. Mounting plates 9 are provided on the rear surfaces of the two mounting bases 2. Large connecting ears 10 are installed on the rear surfaces of the two mounting plates 9 near the connecting plates 1 and 5. 0. When the external hydraulic equipment is running, it can pull the mounting hole on the upper side of the large connecting ear 10, and rotate the base plate 1 around the mounting hole on the lower side of the large connecting ear 10 as the axis, thereby controlling the displacement of the base plate 1. Small connecting ears 11 are provided on the rear surface of the two mounting plates 9 away from the connecting plate 5. The small connecting ears 11 are connected to the mounting plates 9 by welding. By setting the small connecting ears 11, the mounting hole of the small connecting ears 11 and the mounting hole on the lower side of the large connecting ear 10 are coaxial and of the same size and installed in the same shaft, sharing the pressure generated on the inner side of the base plate 1 when it is pressed against the coal mine.

[0024] Please see Figures 1-4 In this embodiment, a support plate 3 12 is provided at the middle position of the upper surface of each of the two mounting bases 2. The right surface of each of the two support plates 3 12 is provided with symmetrical mounting holes 3 13. By providing the support plates 3 12, the support plates 3 12 are fixed in position by the pins in the non-working state through the two symmetrical mounting holes 3 13, preventing accidental operation. A connecting plate 2 14 is provided at the middle position of the upper surface of the base plate 1. The left surface of the connecting plate 2 14 is provided with mounting holes 4 15. By providing the connecting plate 2 14, the connecting plate 2 14 is installed and connected to the small connecting lug 11 on the same axis through the mounting holes 4 15, sharing the pressure generated in the middle position when the base plate 1 is against the coal mine. A connecting groove 16 is provided on the front side of the upper surface of the two mounting bases 2. The upper surface of the base plate 1 is provided with mounting holes 5 17 on the lower side of the two connecting grooves 16. By providing mounting holes 5 17, the material usage is reduced while ensuring strength, and the stress distribution of the structure is optimized.

[0025] During operation, a second support plate 8 is installed, which provides secondary fixation to the side of the first connecting plate 5, thereby strengthening the installation strength of the first connecting plate 5 and making it more stable during use. A large connecting lug 10 is provided, allowing external hydraulic equipment to extend or retract the base plate 1 by pulling the upper mounting hole of the large connecting lug 10 and rotating it around the lower mounting hole, thus controlling the displacement of the base plate 1. A small connecting lug 11 is also provided, with its mounting hole connected to the lower mounting hole of the large connecting lug 10. The base plate 1 is coaxially and of the same size and installed on the same shaft, which shares the pressure generated on the inner side when it is pressed against the coal mine. By setting support plate 3 12, support plate 3 12 can fix the position of base plate 1 in the non-working state by means of pin through two symmetrical mounting holes 3 13 to prevent accidental operation. By setting connecting plate 2 14, connecting plate 2 14 is installed on the same shaft with small connecting lug 11 through mounting hole 4 15, which shares the pressure generated in the middle position when base plate 1 is pressed against the coal mine. By setting mounting hole 5 17, the material usage is reduced while ensuring strength, and the stress distribution of the structure is optimized.

[0026] Through the above steps, by setting up a connecting plate 5, which forms a connecting ear structure through mounting holes 6 and 7, a collaborative load-bearing system is formed with the original connecting ear while maintaining the original connecting ear's installation function. This avoids the original connecting ear from breaking during use and solves the problem that the existing support side plate lacks the function of stress distribution. Without the stress distribution function, stress may concentrate on the root of the connecting ear, leading to weld cracking and deformation of the connecting ear seat.
