[0002] In the underground engineering operation such as mining, tunnel construction, the hydraulic support as the key equipment of guaranteeing the safe and stable operation space, the stability of its base is very important, however, the actual operation environment is complex and changeable, and brings many challenges to the stable support of the hydraulic support;

[0003] In the mining site, the roadway ground condition is complex, and there are often soft coal gangue accumulation layer, muddy area or uneven rock surface, when the hydraulic support base supports on this kind of ground, the sinking problem is prone to occur, which leads to the inclination of the support, not only affects the effective support of the support to the roof, and seriously may also cause roof collapse and other safety accidents, endanger the life safety of the operation personnel, and cause huge economic loss;

[0004] In the tunnel construction scene, due to the vibration generated in the construction process, plus the possible water accumulation in the tunnel ground, so that the hydraulic support base faces the anti -slip problem, once the support slides, will interfere with the construction progress, increase the construction cost, and at the same time, the construction safety is seriously threatened;

[0005] But the traditional hydraulic support base design is relatively simple, only relies on its own weight and limited support area to maintain stability, it is difficult to adapt to complex ground conditions, although part of the improved scheme attempts to increase the base area, but the effect is poor in anti -slip and sinking of soft ground, and lacks flexible and effective adjustment mechanism, therefore, a hydraulic support base anti -slip and anti -sinking device is provided. UTILITY MODEL CONTENTS

[0006] Therefore, the utility model embodiment hopes to provide a hydraulic support base anti -slip and anti -sinking device to solve or alleviate the technical problems in the prior art, at least provide a beneficial choice.

[0007] The technical scheme of the utility model embodiment is realized as follows: a hydraulic support base anti -slip and anti -sinking device, including base and the inside installation of base expansion mechanism, still including:

[0008] Fixed mechanism, installed on the expansion mechanism;

[0009] Among them:

[0010] The unfolding mechanism comprises a first fixed column, a second circular groove and a first circular groove are arranged in the first fixed column, a second fixed column is rotatably arranged on the second circular groove, a third circular groove is arranged in the second fixed column, a first threaded rod is mounted on the outer side of the second fixed column, a knob is mounted on one side of the second fixed column, and a fixed block is fixedly mounted on the outer side of the first fixed column.

[0012] Further preferably, the threaded hole and the first threaded rod are in threaded connection, the first fixed column is located in the limiting groove, a support frame is mounted on the top of the base, and the limiting columns are respectively mounted on the base and the support frame.

[0013] Further preferably, the fixed block, the connecting rod, the limiting block and the fixed plate are all slidingly arranged in the fixed groove, and the fixed groove, the fixed block, the limiting block and the fixed plate are all provided with four groups.

[0016] Further preferably, the diameter of the third circular groove is smaller than that of the first circular groove, and the diameter of the first circular groove is smaller than that of the second circular groove.

[0017] Further preferably, an anti-skid pad is arranged on the bottom of the base.

[0018] The above technical scheme is adopted in the embodiment of the utility model, and the following advantages are achieved.

[0019] I. This utility model allows the operator to rotate a knob, causing the second fixed column to rotate around the second circular groove of the first fixed column. Simultaneously, the first threaded rod interacts with the threaded hole on the base, causing the unfolding mechanism to extend outward. At this time, the fixed block, connecting rod, limiting block, and fixed plate slide and unfold within the fixed groove. The four sets of such structures work together to increase the contact area between the base and the ground, adding a stable chassis to the hydraulic support, distributing the weight of the equipment over a larger area, effectively reducing the pressure per unit area, greatly improving the stability of the hydraulic support under different working conditions, effectively reducing problems such as tilting and shaking caused by unstable support, and ensuring operational safety and normal equipment operation.

[0020] II. This utility model utilizes the coordinated operation of the threaded sleeve, the second threaded rod, and the fixing head of the fixing mechanism. Rotating the rotating rod drives the second threaded rod to rotate, allowing the fixing head to be tightly pressed against the ground or support. The coordinated operation of multiple fixing mechanisms further strengthens the connection between the hydraulic support base and the ground, effectively preventing displacement of the base during operation and ensuring the stability of the entire hydraulic support system.

[0021] Third, this utility model increases the friction between the base and the ground by setting an anti-slip pad at the bottom of the base. Under harsh ground conditions such as wet, slippery, and muddy ground, it can effectively prevent the support from sliding. At the same time, the expansion mechanism expands the support area and the fixing mechanism strengthens the support, reducing the pressure of the base on the ground from multiple aspects, preventing the base from sinking into soft ground, and ensuring the stable operation of the hydraulic support under various ground conditions, thus improving the versatility and reliability of the equipment.

[0034] As Figures 1-4 The utility model embodiment provides a hydraulic support base anti -skidding and anti -sinking device, including base 1 and the inside installation of base 1 has unfolding mechanism 6, still including:

[0035] Fixed mechanism 7 is installed on unfolding mechanism 6;

[0038] In this embodiment, the support range of the device can be adjusted by unfolding mechanism 6, and fixed mechanism 7 is used to further fix the device, and the combination of the two enhances the stability of base 1, thereby realizing the functions of anti-skidding and anti-sinking.

[0039] Specifically, the connecting rod 606 is hinged to the fixed block 605, the side of the connecting rod 606 away from the fixed block 605 is hinged to the limit block 607, the bottom of the limit block 607 is fixedly installed with the fixed plate 608, the fixed plate 608 is fixedly installed with the threaded sleeve 701, the third circular groove 621 and the first circular groove 611 are provided with the limit column 8, and the base 1 is provided with the fixed groove 3, the threaded hole 4 and the limit groove 5.

[0040] As a preferred embodiment, when the knob 604 is rotated, the second fixed column 602 is rotated, and the unfolding mechanism 6 is unfolded or contracted through threaded transmission, so as to adjust the support area of the device.

[0041] Specifically, the threaded hole 4 and the first threaded rod 603 are in threaded connection, the first fixed column 601 is located in the limit groove 5, the top of the base 1 is installed with the support frame 2, the two sides of the limit column 8 are installed on the base 1 and the support frame 2 respectively, the fixed groove 3 provides a track for the sliding of the fixed block 605, the connecting rod 606, the limit block 607 and the fixed plate 608, and ensures the accurate movement track of them in the unfolding and contraction process.

[0042] Specifically, the fixed block 605, the connecting rod 606, the limit block 607 and the fixed plate 608 all slide in the fixed groove 3, and the fixed groove 3, the fixed block 605, the limit block 607 and the fixed plate 608 are all provided with four groups.

[0043] It should be noted that the four sets of fixed slots 3, fixed blocks 605, limiting blocks 607 and fixed plates 608 are arranged to enable the expansion mechanism 6 to expand uniformly in all directions, thereby increasing the supporting area of the device and improving the anti-skid and anti-sinking performance of the device. Meanwhile, the four sets of symmetrical structures make the device more balanced when subjected to stress, thereby further enhancing the stability of the device.

[0044] Specifically, the fixing mechanism 7 comprises a threaded sleeve 701, a second threaded rod 702 threadedly connected to the threaded sleeve 701, a fixed head 703 fixedly installed on one side of the second threaded rod 702, a rotating shaft 704 fixedly installed on the side of the second threaded rod 702 away from the fixed head 703, and a rotating rod 705 arranged on the rotating shaft 704.

[0045] As a preferred embodiment, the fixed head 703 can be in close contact with the ground or other support after being extended, thereby increasing the friction and adhesion between the device and the supporting surface and fixing the device to prevent it from sliding or sinking.

[0046] Specifically, the threaded sleeve 701, the second threaded rod 702, the fixed head 703, the rotating shaft 704 and the rotating rod 705 are all arranged in four sets.

[0048] Specifically, the diameter of the third circular groove 621 is smaller than that of the first circular groove 611, and the diameter of the first circular groove 611 is smaller than that of the second circular groove 612.

[0049] It should be noted that the circular grooves with different diameters are designed to meet the installation and movement requirements of different components, and the diameter difference also helps to distinguish different functional areas, facilitating accurate installation and positioning of the components and ensuring normal operation of the expansion mechanism 6.

[0050] Specifically, the bottom of the base 1 is provided with a non-slip pad.

[0051] As a preferred embodiment, the non-slip pad directly contacts the ground, thereby increasing the friction between the base 1 and the ground and effectively preventing the device from sliding during operation, thereby improving the anti-skid performance of the device and enhancing the stability of the entire hydraulic support.
