Description

Technical Field

[0001] The utility model relates to the technical field of suspended single hydraulic props, in particular to a protective top cover of a suspended single hydraulic prop. Background Art

[0002] As we all know, the top cover, a key component of a single hydraulic prop, plays a crucial dual role: on the one hand, it provides the necessary support force; on the other hand, it is responsible for effectively transmitting the pressure exerted on the top to the piston, cylinder, and bottom cover, and ultimately dissipating it to the ground. However, the protective top cover design of the suspended single hydraulic prop currently widely used in the market is relatively simple, with a significant disadvantage: the lack of support angle adjustment function.

[0003] This design limitation means that when the top cover needs to support an inclined object, it cannot adjust accordingly to the object's tilt angle, which in turn increases wear on the contact surface between the top cover and the object. This uneven and excessive wear not only shortens the service life of the top cover, but also increases material consumption and maintenance costs during operation. Utility Model Content

[0019] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0020] The protective top cover of the suspended single hydraulic prop according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, the protective top cover of the suspended single hydraulic prop according to the embodiment of the present invention may include a fixing mechanism 10 , an adjusting mechanism 20 and a supporting mechanism 30 .

[0022] The fixing mechanism 10 may include a sleeve 11 and two fixing members 12. Mounting slots 101 are defined on the inner walls of the sleeve 11 on both sides, and the two fixing members 12 are movably positioned within the corresponding mounting slots 101. The two fixing members 12 are used to secure the sleeve 11 to the output end of a single hydraulic support (not shown).

[0023] The adjusting mechanism 20 is fixedly disposed on the sleeve 11 , and the supporting mechanism 30 is fixedly disposed on the adjusting mechanism 20 , wherein the adjusting mechanism 20 is used to adjust the supporting angle of the supporting mechanism 30 .

[0024] In order to clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 3 As shown, the fixing member 12 may include an arc-shaped clamping plate 121 , two tension springs 122 and a handle bolt 123 .

[0025] Among them, the arc-shaped clamping plate 121 is movably set in the installation groove 101, and the two tension springs 122 are arranged side by side in the installation groove 101, and one end of the tension spring 122 is fixedly connected to the arc-shaped clamping plate 121, and the other end of the tension spring 122 is fixedly connected to the side wall of the installation groove 101.

[0026] It should be noted that, in order to improve the clamping and fixing effect of the arc-shaped clamping plate 121 , anti-slip grooves may be further provided on the inner arc-shaped surface of the arc-shaped clamping plate 121 .

[0027] The handle bolt 123 is threadedly connected to the wall of the sleeve 11 , and the top end of the handle bolt 123 is in contact with the arc-shaped clamping plate 121 .

[0028] It can be understood that when the adjustment mechanism 20 and the support mechanism 30 need to be fixed on the output end of the single hydraulic support, the relevant staff first needs to put the sleeve 11 on the output end of the single hydraulic support, and then the staff manually rotates the handle bolt 123. The rotating handle bolt 123 pushes the arc-shaped clamping plate 121 to move closer to the output end of the single hydraulic support and stretches the tension spring 122, and then the output end of the single hydraulic support is clamped by the two arc-shaped clamping plates 121 moving toward each other, thereby fixing the sleeve 11 on the output end of the single hydraulic support.

[0029] When the sleeve 11 needs to be removed from the output end of the single hydraulic support, the staff can manually reverse the handle bolt 123. At this time, the handle bolt 123 moves away from the arc-shaped clamping plate 121, and the arc-shaped clamping plate 121 resets and moves under the tension of the tension spring 122, thereby releasing the clamping of the output end of the single hydraulic support.

[0030] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the adjustment mechanism 20 may include a support cylinder 21 , a rotary disk 22 , a bolt 23 , a spring 24 , a first inner gear ring 25 , a first outer gear ring 26 and a support component 27 .

[0031] The supporting cylinder 21 is fixedly arranged on the sleeve 11 , the turntable 22 is movably arranged in the supporting cylinder 21 , and one end of the turntable 22 passes through the supporting cylinder 21 .

[0032] One end of the bolt 23 passes through the turntable 22 and is threadedly connected to the end wall of the support cylinder 21. The spring 24 is sleeved on the bolt 23, and one end of the spring 24 is fixedly connected to the end wall of the support cylinder 21, and the other end of the spring 24 is in contact with the other end of the turntable 22.

[0033] The first inner gear ring 25 is fixed in the support cylinder 21 , the first outer gear ring 26 is sleeved and fixed on the turntable 22 , and the first outer gear ring 26 is meshed with the first inner gear ring 25 , and the support component 27 is fixed on the end wall of the support cylinder 21 .

[0034] In order to clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 2 As shown, the support component 27 may include a support column 271 , a second outer gear ring 272 and a second inner gear ring 273 , wherein the support column 271 is fixedly disposed on the end wall of the support cylinder 21 .

[0035] The second outer gear ring 272 is sleeved and fixed on the support column 271 , and the second inner gear ring 273 is meshed with the second outer gear ring 272 .

[0036] Furthermore, in one embodiment of the present invention, Figure 1-Figure 3 As shown, the support mechanism 30 may include two support plates 31 and a cover plate 32, wherein the two support plates 31 are fixedly arranged side by side and vertically on the cover plate 32, one of the support plates 31 is fixedly connected to the second inner gear ring 273, and the other support plate 31 is fixedly connected to the turntable 22. It should be noted that in order to increase the friction force on the top of the cover plate 32 and improve the stability when supporting an object on a flat surface, anti-slip grooves or anti-slip pads may also be provided on the top wall of the cover plate 32.

[0037] Specifically, when the angle of the cover plate 32 needs to be adjusted, the operator can manually press the rotary disk 22 to move it toward the support cylinder 21. The moving rotary disk 22 drives the first outer ring gear 26, the two support plates 31, the cover plate 32, and the second inner ring gear 273 to move synchronously and compress the spring 24. At this time, the first outer ring gear 26 is disengaged from the first inner ring gear 25, and the second inner ring gear 273 is disengaged from the position limit of the second outer ring gear 272.

[0038] The staff then manually rotates the turntable 22 to adjust the support angle of the cover plate 32. When the support angle of the cover plate 32 is adjusted to the appropriate position, the staff releases the turntable 22. At this point, the turntable 22 loses its pressing force and, under the tension of the spring 24, resets. The reset turntable 22 then synchronously resets the first outer ring gear 26, the two support plates 31, the cover plate 32, and the second inner ring gear 273. The first outer ring gear 26 meshes with the first inner ring gear 25 to limit the position of the turntable 22, and thus the cover plate 32. Simultaneously, the second inner ring gear 273 meshes with the second outer ring gear 272 to limit the position of the cover plate 32, thereby securing the cover plate 32.

[0039] In summary, the protective top cover of the suspended single hydraulic support in the embodiment of the present invention can adapt to the support requirements of different inclination angles, effectively reduce excessive wear caused by angle mismatch, and thus significantly extend the service life of the top cover and the entire single hydraulic support.
