Description

Technical Field

[0001] This application belongs to the field of coal mine equipment technology, specifically relating to a hydraulically adjustable support device. Background Technology

[0002] In the domestic hydraulic support column maintenance industry, the existing technology for adjusting the height of the cylinder support device during column loading tests mainly relies on manual adjustment of the lead screw or the cylinder support frame spacing. However, this manual, close-range operation of the valve has significant drawbacks. On the one hand, the efficiency of manually adjusting the lead screw or cylinder support frame spacing is extremely low, failing to meet the requirements for high-efficiency operation. This is because manual drive is slow, and the adjustment process requires repeated calibration and coordination, resulting in a long time consumption. On the other hand, this operation method is prone to injury due to misoperation, posing a significant safety hazard. Due to the lack of an effective overload protection mechanism for manual operation, and the fact that operators need to be in close contact with heavy columns with an outer diameter of 706mm and a total weight of 7.275t, improper operation can easily lead to dangerous situations such as column tilting or falling. At the same time, this manual adjustment method also significantly increases the labor intensity of operators, which can easily cause physical damage in the long run. This is because the adjustment process requires manual pushing of heavy components and continuous force operation, and the limited working space and lack of auxiliary force-saving devices result in enormous physical exertion.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] See also Figure 1-4 As shown, an embodiment of this application provides a hydraulically adjustable support device, comprising: Base plate 1, with a connecting plate 2 provided on one side of the base plate 1; Support base 3, a plurality of support bases 3 are slidably disposed on the base plate 1. The support base 3 includes a support frame 31, a first driving member 32 and a support plate 33. The support plate 33 is slidably disposed on the support frame 31 and has a support groove. The first driving member 32 is disposed between the support frame 31 and the support plate 33 and is used to drive the support plate 33 to move in a first direction. The second driving member 4 is disposed between the connecting plate 2 and the support frame 31 and between each pair of support frames 31. The second driving member 4 can drive the support frame 31 to move in a second direction perpendicular to the first direction.

[0022] The hydraulically adjustable support device provided in this embodiment includes a base plate 1, a support base 3, and a second driving member 4. The support base 3 further includes a support frame 31, a first driving member 32, and a support plate 33. The support plate 33 is slidably mounted on the support frame 31 and has a support groove. The first driving member 32 is located between the support frame 31 and the support plate 33 and is used to drive the support plate 33 to move along a first direction. The second driving member 4 is disposed between the connecting plate 2 and the support frame 31, as well as between pairs of support frames 31, and can drive the support frame 31 to move along a second direction perpendicular to the first direction.

[0023] Based on this, when supporting heavy workpieces (such as hydraulic support columns with an outer diameter of 706mm and a total weight of 7.275t), the first driving component 32 can be used to drive the support plate 33 to move in the first direction, adjusting the support height to meet the support requirements of different heights; the second driving component 4 drives the support frame 31 to move in the second direction, adjusting the spacing of multiple support seats 3 to adapt to workpieces of different lengths. The cooperation of multiple support seats 3, combined with the driving adjustments of the first driving component 32 and the second driving component 4 in different directions, allows for flexible and precise support of the workpiece, ensuring the stability of the support. This method replaces the manual adjustment of the screw or cylinder support frame 31 spacing. On the one hand, hydraulic drive adjustment is fast and efficient, significantly improving work efficiency and meeting the requirements of high-efficiency production and maintenance; on the other hand, it eliminates the need for close-range manual operation by workers, avoiding safety hazards such as hand and foot pinching, and accidental injury that may occur during manual adjustment, reducing the labor intensity of workers and alleviating the pressure of on-site safety management.

[0024] It is understandable that the first direction is the vertical direction, and the first driving component 32 drives the support plate 33 to move in the vertical direction to adjust the support height and meet the support requirements of different heights; the second direction is the horizontal direction, and the second support component adjusts the spacing between the support seats 3 in the horizontal direction, which can adapt to workpieces of different lengths and improve the stability of the support.

[0025] It is understandable that the first drive component 32 and the second drive component 4 can be hydraulically driven components such as hydraulic cylinders, using the stable power output of the hydraulic system to ensure a smooth and reliable adjustment process, while also facilitating remote control by staff.

[0026] In one possible implementation, the support frame 31 includes: A fixing plate 311 is slidably disposed on the base plate 1; A limiting plate 312 is symmetrically arranged on the base plate 1. A sliding groove is provided on the opposite side of the limiting plate 312. The two ends of the support plate 33 are slidably arranged in the sliding groove. The first driving member 32 is symmetrically arranged between the base plate 1 and the support plate 33.

[0027] In this technical solution, the support frame 31 includes a fixed plate 311 and a limiting plate 312. The fixed plate 311 is slidably mounted on the base plate 1, and the limiting plate 312 is symmetrically and vertically mounted on both sides of the base plate 1. A sliding groove is provided on the opposite side of the limiting plate 312, and the two ends of the support plate 33 are slidably mounted in the sliding groove. At the same time, the first driving member 32 is symmetrically arranged between the base plate 1 and the support plate 33.

[0028] When the device is performing support operations, the fixed plate 311 can slide on the base plate 1, facilitating the overall movement of the support base 3, and the second driving component 4 can better adjust the position of the support base 3. The groove on the limiting plate 312 plays a limiting and guiding role for the support plate 33, ensuring that the support plate 33 can move stably in the first direction along the groove under the drive of the first driving component 32, avoiding deviation or shaking of the support plate 33 during movement, and ensuring the accuracy and stability of height adjustment. The symmetrically arranged first driving component 32 can make the driving force on the support plate 33 more balanced, further improving the smoothness of the movement of the support plate 33. Thus, the hydraulic adjustable support device can more stably and reliably adjust the height when supporting the workpiece, providing a good support effect for the workpiece, and helping to improve the quality and efficiency of heavy workpiece loading tests such as hydraulic support columns.

[0029] It is understandable that there are two first drive components 32, whose bottoms are fixedly mounted on the base plate 1 by bolts, and whose output ends are fixedly connected to the support plate 33 by the fixing plate 311 and bolts.

[0030] In one feasible implementation, the second driving member 4 is disposed between the connecting plate 2 and the fixing plate 311 and between each pair of the fixing plates 311.

[0031] In this technical solution, the second driving component 4 is disposed between the connecting plate 2 and the fixing plate 311, as well as between the two fixing plates 311.

[0032] When it is necessary to adjust the position of a single support 3 relative to the connecting plate 2 to accommodate the support point requirements of different workpieces in the length direction, the second driving component 4 on the connecting plate 2 can push or pull the fixed plate 311 to slide on the base plate 1, thereby achieving fine adjustment of the position of the support 3. When it is necessary to adjust the spacing between multiple support 3s to accommodate workpieces of different lengths, the second driving component 4 located between pairs of fixed plates 311 can lengthen or shorten to change the spacing between adjacent fixed plates 311, thereby quickly and accurately adjusting the distribution of multiple support 3s to meet the support requirements of the workpiece.

[0033] In one feasible implementation, the fixing plate 311 is provided with sliding plates 5 on both sides, the sliding plates 5 are provided with sliding grooves, and the bottom plate 1 is provided in the sliding grooves on both sides.

[0034] The bottom of the base plate 1 is provided with pads 6 at intervals, and the bottom of the base plate 1 is located below the slide plate 5.

[0035] In this technical solution, sliding plates 5 are provided on both sides of the fixed plate 311, and the sliding grooves on the sliding plates 5 match the two ends of the base plate 1, so that the fixed plate 311 can slide on the base plate 1. The pads 6 are installed at intervals on the bottom of the base plate 1. By limiting the bottom of the pads 6 to be below the bottom of the sliding plates 5, the pads 6 can support the base plate 1 without hindering the sliding of the sliding plates 5 on the base plate 1.

[0036] In one feasible implementation, the support groove is a V-shaped structure.

[0037] It also includes a support pad 7, which is disposed on the support groove.

[0038] This technical solution also includes a support pad 7, which is detachably installed on the support groove. The support pad 7 provides protection during support of the groove. When supporting heavy cylindrical workpieces such as hydraulic support columns, compared to flat or curved grooves, the two inclined surfaces of the V-groove can form two stable points of contact with the outer wall of the workpiece, automatically centering the workpiece and preventing it from shifting due to external forces or its own weight during support. This limits radial movement and provides stable support for subsequent height adjustment and loading tests. The support pad 7 supports the workpiece, reducing the probability of damage to the support groove during use, lowering maintenance costs, extending the service life of the support plate 33, and ensuring the safety and reliability of the hydraulic support column loading test.

[0039] In one feasible implementation, the support pad 7 includes: V-shaped plate 71; A fixing seat 72 is disposed at the bottom of the V-shaped plate 71, and a fixing groove matching the support groove is provided on the fixing seat 72; Rolling elements 73, a plurality of rolling elements 73 are spaced apart on the V-shaped plate 71.

[0040] The rolling element 73 is a ball bearing.

[0041] In this technical solution, the support pad 7 includes a V-shaped plate 71, a fixed seat 72, and multiple rolling elements 73. The fixed seat 72 is installed on the middle of both sides of the V-shaped plate 71, and the fixing groove on it matches the support groove, ensuring that the support pad 7 is stably installed in the support groove and preventing displacement or detachment when bearing heavy workpieces, thus ensuring the stability of the support. Multiple balls are spaced apart on the V-shaped plate 71. When it is necessary to adjust the axial position of the workpiece in the support groove, the balls can convert the sliding friction between the workpiece and the V-shaped plate 71 into rolling friction, greatly reducing the friction force. This allows operators to more easily push heavy workpieces for fine-tuning of position, reducing manpower consumption. At the same time, the wear generated by rolling friction is smaller, which can protect the outer wall of the workpiece from scratches and extend the service life of the support pad 7. In addition, the spaced arrangement of the balls can avoid large-area contact between the workpiece and the V-shaped plate 71, reducing the accumulation of oil and impurities on the contact surface and facilitating subsequent cleaning and maintenance.

[0042] Understandably, the rolling elements 73 are mounted in a rectangular array on the V-shaped plate 71.

[0043] In one feasible implementation, a support rib 74 is provided between the fixed base 72 and both ends of the V-shaped plate 71. In this technical solution, by installing support ribs 74 between the fixed base 72 and both ends of the V-shaped plate 71, the structural strength of the support pad 7 is improved and the probability of damage during use is reduced.

[0044] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
