Description

Technical Field

[0001] This application belongs to the technical field of coal mining equipment, and in particular relates to an advanced hydraulic support. Background Technology

[0002] Hydraulic supports are high-strength steel structural components hinged together and driven by hydraulic cylinders. Their main function is to withstand the pressure on the roof after underground mining, and their structural components bear very large loads. Some working faces have a large inclination angle, and the corresponding roadway roof is also inclined. This means that conventional advance supports cannot effectively support the roadway roof and cannot stably support the inclined roof.

[0003] When conventional advanced support systems face inclined roofs, manual adjustment of the overall position of the support system or replacement of specialized roof beam components is usually required to adapt to the roof angle. This process is not only cumbersome and time-consuming, but it can also lead to interruptions in support work and affect the construction progress. Furthermore, while some support systems have simple angle adjustment functions, the adjustment mechanisms often use mechanical linkages, resulting in low adjustment accuracy and slow response speed. Consequently, the fit between the support system and the inclined roof is consistently difficult to meet standards, making it impossible to form a stable and reliable support system. Utility Model Content

[0004] This application provides an advanced hydraulic support. One end of the upper top beam is hinged to the top of the support frame to form a stable rotation fulcrum, and the other end is connected to the top of the support frame through a first hydraulic cylinder. The extension and retraction of the first hydraulic cylinder drives the upper top beam to rotate flexibly around the hinge point, realizing real-time and precise adjustment of the tilt angle of the upper top beam. It can quickly adapt to roadway roofs with different tilt angles without the need for manual adjustment or replacement of parts. This solves the problems of low adjustment accuracy, slow response speed, and difficulty in achieving the required fit between the support and the tilted roof, which makes it impossible to form a stable and reliable support system.

[0005] This application provides an advanced hydraulic support, which is installed in a roadway to support an inclined roof. The advanced hydraulic support includes a support frame and an adapter frame installed on top of the support frame.

[0008] In one feasible implementation, the support frame further includes a bottom support mechanism and uprights; The bottom support mechanism includes two bases arranged opposite each other along the width direction of the bottom top beam, and push-pull jacks respectively installed on the two bases; Each of the bases is provided with a plurality of columns, one end of which is hinged to the base and the other end of which is hinged to the bottom top beam; The column is used to drive the bottom top beam to rise and fall vertically, so as to adjust the overall height of the support.

[0009] In one feasible implementation, the supporting frame further includes a four-bar linkage, which includes an upper link, a lower link, and an inclined beam; One end of the upper connecting rod is hinged to the upper part of the base, and the other end is hinged to the middle part of the inclined beam. One end of the lower connecting rod is hinged to the lower part of the base, and the other end is hinged to the lower part of the inclined beam. Two upper connecting rods and two lower connecting rods are provided symmetrically. The top of the inclined beam is hinged to the middle of the lower surface of the bottom top beam.

[0010] In one feasible implementation, the support frame further includes a front beam mechanism, with two front beam mechanisms respectively disposed at both ends of the bottom top beam along its length. The front beam mechanism includes a fourth hydraulic cylinder and a front beam. The end of the front beam is hinged to the bottom top beam, one end of the fourth oil cylinder is hinged to the bottom top beam, and the other end is hinged to the bottom of the front beam. The fourth hydraulic cylinder is used to drive the front beam to rotate relative to the bottom top beam around the hinge point.

[0011] In one feasible implementation, the front beam mechanism further includes a fifth hydraulic cylinder and a front cantilever beam; The end of the cantilever beam is hinged to the end of the front beam away from the bottom top beam, one end of the fifth oil cylinder is hinged to the front beam, and the other end is hinged to the bottom of the cantilever beam. The fifth hydraulic cylinder is used to drive the cantilever beam to rotate relative to the front beam around the hinge point.

[0013] In one feasible implementation, the top protection mechanism further includes a seventh hydraulic cylinder and a second top protection plate; The end of the second top protection plate is hinged to the end of the first top protection plate away from the bottom top beam, and one end of the seventh oil cylinder is hinged to the first top protection plate and the other end is hinged to the second top protection plate. The seventh hydraulic cylinder is used to drive the second top plate to rotate relative to the first top plate around the hinge point.

[0014] In one feasible implementation, the inclined top beam mechanism further includes a movable side guard plate between beams, which is connected to the upper top beam; Multiple sets of the inclined top beam mechanism are arranged sequentially along the length of the bottom top beam; in two adjacent sets of the inclined top beam mechanism, the movable side guard plate between the beams of one set overlaps and fits with the upper top beam of the other set to compensate for the gap between the sets.

[0015] This application provides an advanced hydraulic support system. Through a combined structure of a support frame and an adapter frame, the support frame provides a stable foundation for the entire support system, while its top hinge provides reliable support for the installation and rotation of the adapter frame, solving the problems of fixed overall structure and difficulty in adjustment inherent in traditional supports. The inclined top beam mechanism in the adapter frame includes an upper top beam and a first hydraulic cylinder. The upper top beam, as the core support component directly contacting the inclined roof of the roadway, has one end hinged to the top of the support frame to form a stable rotation fulcrum, and the other end connected to the top of the support frame via the first hydraulic cylinder. The extension and retraction of the first hydraulic cylinder drives the upper top beam to rotate flexibly around the hinge point, enabling real-time and precise adjustment of the upper top beam's inclination angle. This allows for rapid adaptation to roadway roofs with different inclination angles without manual adjustment or component replacement, effectively solving the problems of fixed top beam angle and poor adaptability in traditional supports, while also avoiding the inefficiency and work interruptions caused by manual adjustment.

[0016] Furthermore, the upper roof beam is driven by the first hydraulic cylinder to achieve a tight fit with the inclined roof of the roadway, which can evenly transfer the roof load to the supporting frame. This avoids local voids and stress concentration caused by loose fit between the roof beam and the roof, significantly improving the load-bearing stability and support reliability of the support system. It also reduces the risk of safety accidents such as roof collapse and support tilting, ensuring the safety of underground workers and the smooth progress of construction. At the same time, the hydraulic drive of the first hydraulic cylinder has higher adjustment precision and faster response speed than the traditional mechanical linkage transmission. It can finely adjust the posture of the upper roof beam in real time according to the dynamic changes in the inclination angle of the roadway roof, further improving the adaptability and support effect of the support system to the inclined roof.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0020] Currently, most supports cannot dynamically adapt to the angle of the inclined roof, requiring manual adjustment of position or replacement of top beam components. This operation is cumbersome, time-consuming, and prone to interrupting support work, affecting construction progress. A few supports with adjustment functions use mechanical linkage transmission, which has low adjustment accuracy, slow response speed, poor fit between the top beam and the inclined roof, and difficulty in forming a stable support system. The advanced hydraulic support provided in this application has one end of the upper top beam 211 hinged to the top of the support frame 100 to form a stable rotation fulcrum, and the other end connected to the top of the support frame 100 through the first hydraulic cylinder 212. The extension and retraction of the first hydraulic cylinder 212 drives the upper top beam 211 to rotate flexibly around the hinge point, realizing real-time and precise adjustment of the inclination angle of the upper top beam 211. It can quickly adapt to roadway roofs with different inclination angles without the need for manual adjustment or replacement of components.

[0021] The following detailed description of the specific structure of the advanced hydraulic support provided in this application is provided in conjunction with the accompanying drawings.

[0022] Reference Figures 1-8As shown, this application embodiment provides an advanced hydraulic support, which is installed in the roadway to support the inclined roof. The advanced hydraulic support includes a support frame 100 and an adapter frame 200 installed on the top of the support frame 100. The adapter frame 200 includes an inclined top beam mechanism 210, which includes an upper top beam 211 and a first hydraulic cylinder 212. The end of the upper top beam 211 is hinged to one end of the top of the support frame 100, one end of the first oil cylinder 212 is hinged to the other end of the top of the support frame 100, and the other end of the first oil cylinder 212 is hinged to the lower surface of the upper top beam 211. The first hydraulic cylinder 212 is used to drive the upper top beam 211 to rotate relative to the supporting frame 100 around the hinge point so that the tilt angle of the upper top beam 211 is adapted to the tilted top plate.

[0023] The advanced hydraulic support provided in this application for supporting the inclined roof of a roadway consists of a load-bearing frame 100 and an adapter frame 200, which work together to achieve precise adaptation and stable support for the inclined roof.

[0024] The supporting frame 100 serves as the basic load-bearing structure of the entire support system, providing installation support and a stable stress-bearing platform for the adapter frame 200. Its structural design must meet the overall support strength requirements to ensure the transmission and distribution of the top plate load. The adapter frame 200 is assembled on top of the supporting frame 100, and its core components include an inclined top beam mechanism 210, which consists of an upper top beam 211 and a first hydraulic cylinder 212.

[0025] The end of the upper top beam 211 is hinged to one end of the top of the support frame 100, forming a stable rotation fulcrum. The first hydraulic cylinder 212 serves as a driving component, with one end hinged to the other end of the top of the support frame 100 and the other end hinged to the lower surface of the upper top beam 211, forming a flexibly adjustable support structure.

[0026] like Figure 2 The right end of the upper top beam 211 is hinged to the right end of the top of the support frame 100, the left end of the first oil cylinder 212 is hinged to the left end of the top of the support frame 100, and the right end of the first oil cylinder 212 is hinged to the middle of the lower surface of the upper top beam 211.

[0027] When the inclination angle of the tunnel roof changes, the first hydraulic cylinder 212 drives the upper roof beam 211 to rotate around the hinge point through the telescopic action, thereby adjusting the inclination angle of the upper roof beam 211 so that it is precisely matched with the angle of the inclination roof, ensuring that the upper roof beam 211 is in close contact with the roof.

[0028] The upper roof beam 211 is rotated by the first hydraulic cylinder 212, allowing for real-time and precise adjustment of its tilt angle. This eliminates the need for manual assistance or component replacement, enabling rapid adaptation to different roadway roof inclinations and resolving the poor adaptability issues of traditional supports. Furthermore, the hydraulically driven angle adjustment offers rapid response, allowing for real-time fine-tuning based on dynamic roof changes, preventing interruptions in support operations, saving manual adjustment time, and ensuring construction progress. The upper roof beam 211 fits tightly against the tilted roof, evenly distributing the roof load to the supporting frame 100, preventing localized open roofs and stress concentrations, reducing the risk of roof collapse, and improving support reliability.

[0029] Reference Figures 2-4 As shown, in some embodiments, the adapter frame 200 further includes a compensation mechanism 220, which includes a second hydraulic cylinder 221 and a telescopic beam 222. One end of the upper top beam 211 is hinged to the support frame 100, and the other end is provided with a first slot, into which the telescopic beam 222 is inserted; The second hydraulic cylinder 221 is disposed in the first slot. The cylinder end of the second hydraulic cylinder 221 is connected to the inner wall of the first slot, and the piston rod end of the second hydraulic cylinder 221 extends toward the open end of the first slot and is connected to the telescopic beam 222. The second hydraulic cylinder 221 is used to drive the telescopic beam 222 to slide back and forth along the first slot.

[0030] The rotating end of the adapter frame 200 is also equipped with a compensation mechanism 220, which consists of a second oil cylinder 221 and a telescopic beam 222, and is used to compensate for the gap that may occur after the angle of the upper top beam 211 is adjusted.

[0031] One end of the upper top beam 211 is hinged to the support frame 100, and the other end is provided with a first slot. The inner end of the first slot extends to the hinged end of the upper top beam 211. The telescopic beam 222 is inserted into the first slot and slidably connected to the inner wall of the first slot to form a telescopic combined top beam structure.

[0032] like Figure 4 As shown, the insertion end of the telescopic beam 222 is provided with a blind groove. The second oil cylinder 221 is installed in the first slot and the blind groove. Its cylinder end is fixedly connected to the inner wall of the first slot, and the piston rod end extends toward the open end of the first slot, inserts into the blind groove, and is connected to the inner wall of the blind groove of the telescopic beam 222.

[0033] After the upper top beam 211 is adjusted to match the inclination angle of the roof slab, if there is a gap between its end and the adjacent support structure or roof slab, the second hydraulic cylinder 221 can drive the telescopic beam 222 to slide back and forth along the first slot. By extending the telescopic beam 222, the gap is filled, ensuring the continuity and integrity of the support, avoiding the risk of collapse caused by partial roof slab suspension, and improving the integrity of the support coverage. The compensation mechanism 220 and the inclined top beam mechanism 210 work together to achieve both angle adaptation and flexible adjustment of the support length, adapting to changes in roof slab shape under different working conditions and expanding the applicability of the support. After the telescopic beam 222 contacts the roof slab, it can transfer the local load to the upper top beam 211, avoiding stress concentration caused by the gap, and further enhancing the overall load-bearing stability of the support.

[0034] Reference Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the support frame 100 includes a bottom top beam 110 and a side pushing mechanism 120 disposed on the bottom top beam 110. The length direction of the bottom top beam 110 is consistent with the extension direction of the roadway. The side pushing mechanism 120 includes a third hydraulic cylinder 121, a side pushing beam 122 and a guide rod 123. The upper top beam 211 and the first oil cylinder 212 are respectively hinged to the two ends of the upper surface of the bottom top beam 110 in the width direction. A second slot is provided on one side of the bottom top beam 110 in the width direction. The open end of the second slot faces the opposite direction of the inclination of the upper top beam 211. The guide rod 123 is inserted into the second slot, and the third cylinder 121 is set in the second slot. The cylinder end of the third cylinder 121 is connected to the inner wall of the second slot, and the piston rod end of the third cylinder 121 extends to the open end of the second slot and is connected to one end of the guide rod 123. The other end of the guide rod 123 extends out of the second slot and is connected to the side push beam 122. The third hydraulic cylinder 121 is used to drive the guide rod 123 to reciprocate along the second slot so that the side push beam 122 abuts against the inner wall of the tunnel, thereby offsetting the horizontal load generated by the inclined roof plate on the support.

[0035] The load-bearing frame 100 includes a bottom top beam 110 and a side pushing mechanism 120, which work together to achieve stable load bearing and horizontal load offsetting functions.

[0036] The bottom top beam 110, as the core component of the supporting frame 100, has its length direction aligned with the direction of the tunnel extension. The bottom top beam 110 provides the mounting foundation for the upper top beam 211, the first hydraulic cylinder 212, and the side-push mechanism 120. The upper top beam 211 and the first hydraulic cylinder 212 are respectively hinged to both ends of the upper surface of the bottom top beam 110 in the width direction, and the side-push mechanism 120 is installed on one side of the bottom top beam 110 in the width direction.

[0037] The side-pushing mechanism 120 consists of a third hydraulic cylinder 121, a side-pushing beam 122, and a guide rod 123. A second slot is provided on one side of the bottom top beam 110 in the width direction. The open end of the second slot faces the opposite direction of inclination to the upper top beam 211, providing a guide path for the side-pushing operation. Figure 1 As shown, the width direction of the bottom top beam 110 is the front-to-back direction. The bottom end of the upper top beam 211 is hinged to the rear end of the upper surface of the bottom top beam 110. The upper end of the upper top beam 211 is inclined forward. A second slot is provided on the front surface of the bottom top beam 110. The inner end of the second slot extends backward, that is, the open end of the second slot faces the opposite direction of the inclination of the upper top beam 211.

[0038] The guide rod 123 can be a columnar rod. Both ends of the side push beam 122 are fixedly connected to the guide rod 123, and the two guide rods 123 on the same side push beam 122 are parallel. The second slot is a circular slot that matches the guide rod 123. The guide rod 123 is inserted into the second slot. The third oil cylinder 121 is built into the second slot. Its cylinder end is fixed to the inner wall of the slot. Its piston rod end is connected to one end of the guide rod 123. The other end of the guide rod 123 extends out of the slot and is fixed to the side push beam 122.

[0039] When the inclined roof plate generates a horizontal load on the support, the third hydraulic cylinder 121 drives the guide rod 123 to reciprocate along the second slot, causing the side push beam 122 to abut against the inner wall of the roadway. The reaction force of the roadway side wall counteracts the horizontal load and maintains the stability of the support posture.

[0040] Reference Figure 1 and Figure 7 As shown, in some embodiments, the support frame 100 further includes a bottom support mechanism 130 and a column 140; The bottom support mechanism 130 includes two bases 131 arranged opposite each other along the width direction of the bottom top beam 110, and push-pull jacks 132 respectively installed on the two bases 131; Each base 131 is provided with multiple columns 140. One end of the column 140 is hinged to the base 131, and the other end is hinged to the bottom top beam 110. The column 140 is used to drive the bottom top beam 110 to rise and fall vertically in order to adjust the overall height of the support.

[0041] The support frame 100 includes a bottom support mechanism 130 and a column 140.

[0042] The bottom support mechanism 130 includes two bases 131 and two push-pull jacks 132. The two bases 131 are arranged opposite each other along the width direction of the bottom top beam 110. As the contact parts between the support and the roadway floor, they must have sufficient ground contact area and load-bearing strength to ensure the overall stability of the support. The two push-pull jacks 132 are respectively installed on the two bases 131 and are used to drive the entire support to move along the roadway direction to adjust the support position.

[0043] Each base 131 is equipped with multiple columns 140. One end of each column 140 is hinged to the base 131, and the other end is hinged to the bottom beam 110, forming a vertical support structure. The columns 140 are hydraulically driven, and their telescopic movement can drive the bottom beam 110 to rise and fall vertically, thereby adjusting the height of the entire support structure. This allows the support structure to adapt to tunnel spaces of different heights, while providing stable support resistance for the bottom beam 110.

[0044] Reference Figure 7 As shown, in some embodiments, the support frame 100 also includes a four-bar linkage 150, which includes an upper link 151, a lower link 152, and an inclined beam 153. One end of the upper connecting rod 151 is hinged to the upper part of the base 131, and the other end is hinged to the middle part of the inclined beam 153. One end of the lower connecting rod 152 is hinged to the lower part of the base 131, and the other end is hinged to the lower part of the inclined beam 153. There are two symmetrical upper connecting rods 151 and lower connecting rods 152. The top of the inclined beam 153 is hinged to the middle of the lower surface of the bottom top beam 110.

[0045] The support frame 100 also includes a four-bar linkage 150, which consists of an upper linkage 151, a lower linkage 152 and an inclined beam 153, and is used to enhance the stability and motion trajectory accuracy of the support during vertical lifting.

[0046] Two upper connecting rods 151 and two lower connecting rods 152 are symmetrically arranged. One end of the upper connecting rod 151 is hinged to the upper part of the base 131, and the other end is hinged to the middle part of the inclined beam 153. One end of the lower connecting rod 152 is hinged to the lower part of the base 131, and the other end is hinged to the lower part of the inclined beam 153, forming a symmetrical four-bar linkage structure. The inclined beam 153 is an integral structure, and its top end is hinged to the middle part of the lower surface of the bottom top beam 110, serving as the core component connecting the four-bar linkage mechanism and the bottom top beam 110.

[0047] When the column 140 drives the bottom top beam 110 to rise and fall vertically, the four-bar linkage 150 constrains the movement trajectory of the inclined beam 153 through the coordinated rotation of the upper link 151 and the lower link 152, thereby ensuring that the bottom top beam 110 always remains in a horizontal state during the rise and fall, avoiding tilting or deviation during the rise and fall process, and at the same time enhancing the overall torsional and anti-tilting capabilities of the support.

[0048] Reference Figure 8 As shown, in some embodiments, the support frame 100 also includes a front beam mechanism 160. Two front beam mechanisms 160 are respectively disposed at both ends of the bottom top beam 110 in the length direction. The front beam mechanism 160 includes a fourth hydraulic cylinder 161 and a front beam 162. The end of the front beam 162 is hinged to the bottom top beam 110, and one end of the fourth oil cylinder 161 is hinged to the bottom top beam 110, and the other end is hinged to the bottom of the front beam 162. The fourth hydraulic cylinder 161 is used to drive the front beam 162 to rotate relative to the bottom top beam 110 around the hinge point.

[0049] The support frame 100 also includes a front beam mechanism 160. The two front beam mechanisms 160 are respectively installed at both ends of the bottom top beam 110 along its length to expand the support range of the support and fill the empty area at the end of the bottom top beam 110.

[0050] The front beam mechanism 160 consists of a fourth hydraulic cylinder 161 and a front beam 162. The end of the front beam 162 is hinged to the bottom top beam 110 and can rotate around the hinge point. Its structural form is adapted to the bottom top beam 110 to ensure the continuity of the support surface. One end of the fourth hydraulic cylinder 161 is hinged to the bottom top beam 110, and the other end is hinged to the bottom of the front beam 162, providing driving force for the rotation of the front beam 162.

[0051] When there is a gap between the end of the bottom top beam 110 and the roadway roof, the fourth hydraulic cylinder 161 drives the front beam 162 to rotate relative to the bottom top beam 110 around the hinge point, adjusting the tilt angle of the front beam 162 so that it fits against the roof, thereby supporting the gap at the end and expanding the overall support coverage of the support system.

[0052] Furthermore, in some embodiments, the front beam mechanism 160 also includes a fifth hydraulic cylinder 163 and a front cantilever beam 164; The end of the front cantilever beam 164 is hinged to the end of the front beam 162 away from the bottom top beam 110, and one end of the fifth oil cylinder 163 is hinged to the front beam 162, and the other end is hinged to the bottom of the front cantilever beam 164. The fifth hydraulic cylinder 163 is used to drive the front cantilever beam 164 to rotate relative to the front beam 162 around the hinge point.

[0053] The front beam mechanism 160 also includes a fifth hydraulic cylinder 163 and a front cantilever beam 164, which further extend the support range and enhance the support capability for the remote roof area.

[0054] The end of the cantilever beam 164 is hinged to the end of the front beam 162 away from the bottom top beam 110, and can rotate around the hinge point. Its length design must meet the support requirements of the far-end open roof area, while also having sufficient structural strength. One end of the fifth hydraulic cylinder 163 is hinged to the front beam 162, and the other end is hinged to the bottom of the cantilever beam 164, providing precise driving force for the rotation of the cantilever beam 164.

[0055] After the current beam 162 is adjusted into place, if there is still a void at its far end, the fifth hydraulic cylinder 163 drives the cantilever beam 164 to rotate relative to the front beam 162 around the hinge point, extending the cantilever beam 164 to the void area and fitting it with the top plate, thereby supporting a deeper void area and forming a multi-level support structure of "bottom top beam + front beam + cantilever beam".

[0056] Reference Figure 8 As shown, in some embodiments, the support frame 100 also includes a top protection mechanism 170. The top protection mechanism 170 and the side pushing mechanism 120 are respectively disposed on both sides of the bottom top beam 110 in the width direction. The top protection mechanism 170 includes a sixth oil cylinder 171 and a first top protection plate 172. The end of the first top plate 172 is hinged to the end of the bottom top beam 110, and one end of the sixth oil cylinder 171 is hinged to the bottom top beam 110, and the other end is hinged to the first top plate 172. The sixth hydraulic cylinder 171 is used to drive the first top protection plate 172 to rotate relative to the bottom top beam 110 around the hinge point.

[0057] The support frame 100 also includes a top protection mechanism 170. The top protection mechanism 170 and the side pushing mechanism 120 are respectively arranged on both sides of the bottom top beam 110 in the width direction, and are used to fill the support gap on the side of the bottom top beam 110 to enhance the lateral top protection effect.

[0058] The roof support mechanism 170 consists of a sixth hydraulic cylinder 171 and a first roof support plate 172. The end of the first roof support plate 172 is hinged to the end of the bottom top beam 110, allowing it to rotate around the hinge point. Its plate surface must cover the open roof area on the side of the bottom top beam 110 to ensure the integrity of the support. One end of the sixth hydraulic cylinder 171 is hinged to the bottom top beam 110, and the other end is hinged to the first roof support plate 172, providing a stable driving force for the rotation of the first roof support plate 172.

[0059] When there is a gap in the roof on the side of the bottom top beam 110 or when lateral roof protection is required, the sixth oil cylinder 171 drives the first roof protection plate 172 to rotate relative to the bottom top beam 110 around the hinge point, so that the first roof protection plate 172 fits against the roof of the side of the roadway, fills the gap in the roof on the side, forms a lateral protective barrier, and prevents the falling of gravel or partial collapse of the roof on the side.

[0060] Furthermore, in some embodiments, the top protection mechanism 170 also includes a seventh hydraulic cylinder 173 and a second top protection plate 174; The end of the second top plate 174 is hinged to the end of the first top plate 172 away from the bottom top beam 110, and one end of the seventh oil cylinder 173 is hinged to the first top plate 172, and the other end is hinged to the second top plate 174. The seventh cylinder 173 is used to drive the second top plate 174 to rotate relative to the first top plate 172 around the hinge point.

[0061] The roof protection mechanism 170 also includes a seventh hydraulic cylinder 173 and a second roof protection plate 174, forming a two-stage roof protection structure, further expanding the lateral roof protection range and enhancing the adaptability to complex lateral roofs.

[0062] The end of the second roof support plate 174 is hinged to the end of the first roof support plate 172 away from the bottom top beam 110, and can rotate around the hinge point. Its structural shape is adapted to the first roof support plate 172 to ensure the continuity and fit of the two-stage roof support structure. One end of the seventh hydraulic cylinder 173 is hinged to the first roof support plate 172, and the other end is hinged to the second roof support plate 174, providing precise driving force for the rotation of the second roof support plate 174.

[0063] Once the first roof support plate 172 is in place, if there is still a lateral open roof area at its far end, the seventh hydraulic cylinder 173 drives the second roof support plate 174 to rotate relative to the first roof support plate 172 around the hinge point, extending the second roof support plate 174 to the far open roof area and fitting it with the roof plate, thereby achieving support for a larger range of lateral open roof areas and forming a multi-level lateral roof support system of "first roof support plate + second roof support plate".

[0064] In some embodiments, the inclined top beam mechanism 210 further includes a movable side guard plate between beams, which is connected to the upper top beam 211. Multiple sets of inclined top beam mechanisms 210 are arranged sequentially along the length of the bottom top beam 110; in two adjacent sets of inclined top beam mechanisms 210, the movable side guard plate between the beams of one set overlaps and fits with the upper top beam 211 of the other set to make up for the gap between the sets.

[0065] The inclined top beam mechanism 210 also includes movable side guard plates between beams; multiple sets of inclined top beam mechanisms 210 are arranged sequentially along the length of the bottom top beam 110. Each set of mechanisms can independently adjust the inclination angle of the upper top beam 211 through the first hydraulic cylinder 212 to adapt to local undulations of the top plate. The inclined top beam mechanism 210 is used to fill the gaps between sets. The end of the movable side guard plate between beams is connected to the upper top beam 211 and can swing relative to the upper top beam 211 to a certain extent.

[0066] In actual operation, in two adjacent sets of inclined top beam mechanisms 210, the movable side guard plate between the beams of one set overlaps and fits with the upper top beam 211 of the other set to form a continuous support surface, avoiding the problem of empty roof caused by the gap between the sets due to the arrangement of multiple sets. At the same time, the independent adjustment feature of each set of mechanisms can ensure precise adaptation to the local shape of the top plate.
