Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a support column device for formwork systems and a construction and installation method thereof. Background Technology

[0002] With the further development of my country's construction industry and the accelerated pace of construction industrialization, a self-climbing steel platform formwork system has emerged. This system features a steel platform at the top, with a support frame below. The entire formwork system climbs via a support column device, offering advantages such as high load-bearing capacity and the ability to serve as a carrier for various equipment. Existing formwork systems with top platforms utilize two types of support column devices: forward-mounted and reverse-mounted. The forward-mounted support system consists of guide rails and columns. The fixed end of the hydraulic cylinder connects to the column, while the movable end connects to the guide rail. The guide rail and column are separate. When the formwork system climbs, the guide rail must be lifted first, followed by the column. This method uses a "3+1" guide seat configuration, with three guide seats fixed to the wall during formwork operation and one guide seat used for rotation. Five layers of hanging brackets are required, one of which is used for removing the guide seats. In the reverse-mounted support system, the guide rail and column are integrated into one unit, called the support frame. An additional hydraulic cylinder bracket is designed. The fixed end of the hydraulic cylinder is connected to the hydraulic cylinder bracket, and the movable end is connected to the support frame. During climbing, the support frame is lifted first, and then the hydraulic cylinder bracket is raised. This method uses a "2+1" type of guide seat. Two guide seats are fixed to the wall when the mold frame is working, and one guide seat is used for turnover. Five layers of hanging brackets need to be installed, one of which is used to remove the guide seat.

[0003] Whether it's a standard or reverse mounting system, the guide seat is an integral structure, making it relatively heavy. Furthermore, during installation, it needs to be inserted into the support frame from top to bottom, requiring ample installation space and making installation inconvenient. Additionally, the support frame experiences single-point stress, resulting in poor safety and stability. Moreover, existing standard and reverse mounting support systems employ a construction method of first lifting the guide rail or support frame and then lifting the column or hydraulic cylinder bracket. Due to the structural limitations of the integral guide seat and the need to fix the hydraulic cylinder bracket, it's impossible to lift the hydraulic cylinder bracket first. The support frame must be fully lifted until it detaches from the bottom guide seat before it can be removed. Since the hanger and support frame move synchronously, an additional hanger is needed after the support frame is fully lifted to remove the bottom guide seat, which requires significant space and increases costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a support column device for a mold frame system, which can facilitate the disassembly and installation between the guide seat and the support frame, and can improve the lifting sequence between the support frame and the hydraulic cylinder bracket, thereby saving the installation space and investment cost of the hanging frame.

[0005] To solve the above-mentioned technical problems, the present invention provides a support column device for a formwork system, including a combined guide seat connected to a building wall, a support frame connected to the combined guide seat, a hydraulic cylinder bracket arranged parallel to the support frame, and a drive cylinder, an upper reversing box, and a lower reversing box connected to the hydraulic cylinder bracket.

[0006] The combined guide seat includes two guide seats arranged opposite each other, which are symmetrically arranged on both sides of the support frame. Both sides of the support frame are provided with limiting edges, and the two guide seats can respectively form a limiting connection with the limiting edges from both sides of the support frame.

[0007] The cylinder bracket has a mounting groove, the drive cylinder and the upper reversing box are located in the mounting groove, the fixed end of the drive cylinder is hinged to the bottom side of the mounting groove, the movable end of the drive cylinder faces upward and is connected to the upper reversing box, and the bottom of the cylinder bracket is connected to the lower reversing box.

[0008] As an improvement to the above solution, the guide seat is provided with a guide wheel mechanism, and the guide wheel mechanism is provided with an installation notch facing the limiting edge. The two installation notches of the guide seat can be inserted into the limiting edge from both sides of the support frame to form a limiting structure.

[0009] As an improvement to the above solution, the guide seat further includes a connecting plate and a guide wheel plate disposed in the middle of the connecting plate. The connecting plate is connected to the building wall, and the guide wheel plate protrudes in a direction away from the building wall. The guide wheel mechanism is disposed on the guide wheel plate.

[0010] As an improvement to the above solution, the guide wheel mechanism includes a first guide wheel and a second guide wheel. The first guide wheel is rotatably disposed on the side of the guide wheel plate near the connecting plate, and the second guide wheel is rotatably disposed on the side of the guide wheel plate away from the connecting plate. Both the first guide wheel and the second guide wheel protrude toward the central axis of the support frame. The gap between the first guide wheel and the second guide wheel constitutes the mounting notch, and the rolling surfaces of the first guide wheel and the second guide wheel can abut against the limiting edge.

[0011] As an improvement to the above solution, multiple working support rods are protruding from both sides of the support frame. The multiple working support rods are evenly distributed along the length direction of the support frame. A hook-shaped plate is provided on the side of the guide seat away from the support frame, and the working support rods can abut against the upper surface of the hook-shaped plate.

[0012] As an improvement to the above solution, both the upper and lower reversing boxes are provided with latches, and the middle part of the support frame is provided with multiple lifting support rods. The multiple lifting support rods are evenly distributed along the length direction of the support frame, and grid holes are provided between adjacent lifting support rods. The latches of the upper and lower reversing boxes can be inserted into the grid holes.

[0013] The present invention also provides a construction and installation method, which includes the following steps using the support column device for the formwork system as described above:

[0014] S01, bolts are pre-embedded in the building wall of the working layer to fix multiple combined guide seats through bolts;

[0015] S02, the extension column and the support frame are fixedly connected on the ground with bolts, and the connected extension column and the support frame are lifted and installed on the combined guide seat;

[0016] S03, Install a top steel platform on the raised column, and install a hanging frame and a formwork under the top steel platform;

[0017] S04, when climbing is required, first lift the cylinder bracket to the new working level, then remove the bottom combined guide seat, and then lift the support frame to the new working level by driving the cylinder.

[0018] S05, push the two guide seats of the combined guide seat into the limiting edge of the support frame from both sides of the support frame along the building wall, and then use nuts to fix the two guide seats to the pre-embedded bolts.

[0019] As an improvement to the above solution, the step of first lifting the hydraulic cylinder support to the new working level includes:

[0020] S41, first move the latches of both the lower and upper commutator boxes downwards, and the moving rod of the drive cylinder will rise upwards and drive the upper commutator box to move upwards;

[0021] S42, then the movable rod of the drive cylinder retracts, at which time the lower edge of the tongue buckle of the upper reversing box abuts against the upper edge of the lifting support rod of the support frame, and the drive cylinder drives the cylinder bracket to move upward as a whole;

[0022] S43, through repeated operations, the cylinder bracket is lifted to a new working level.

[0023] As an improvement to the above solution, the step of removing the bottommost combined guide seat includes:

[0024] S44, after the hydraulic cylinder bracket is lifted to the new working level, the latches of the upper reversing box and the lower reversing box are both moved upwards. The upper edge of the latch of the upper reversing box can abut against the lower edge of the lifting support rod of the support frame. The movable rod of the driving hydraulic cylinder is lifted upwards, and the upper reversing box drives the support frame to move upwards. The support frame stops after moving a preset distance. Then, the nuts of the combined guide seats are loosened, and the two guide seats are removed from both sides of the support frame to complete the removal of the combined guide seats.

[0025] As an improvement to the above solution, the step of lifting the support frame to the new working level by driving the hydraulic cylinder includes:

[0026] S45, after the bottommost combined guide seat is removed, the movable rod of the drive cylinder continues to lift upward and drive the upper reversing box to move upward. The upper edge of the tongue buckle of the upper reversing box can abut against the lower edge of the lifting support rod of the support frame, and the upper reversing box drives the support frame to move upward.

[0027] S46, then the movable rod of the drive cylinder retracts, at which time the upper edge of the tongue buckle of the lower reversing box abuts against the lower edge of the lifting support rod of the support frame to prevent the support frame from falling;

[0028] S47, through repeated operations, the support frame is raised to a new working level.

[0029] Implementing this invention has the following beneficial effects:

[0030] This invention relates to a support column device for a formwork system, comprising a combined guide seat, a support frame, a hydraulic cylinder bracket, a drive hydraulic cylinder, an upper reversing box, and a lower reversing box. Traditional support column devices use an integral structure connected to the building wall and the support frame. In this invention, the combined guide seat includes two opposing guide seats symmetrically arranged on both sides of the support frame. Each guide seat contains a guide wheel mechanism with mounting notches. The mounting notches of the two guide seats can be inserted from both sides of the support frame into the limiting edges of the support frame to form a limiting structure. Furthermore, when used as a turnover guide seat, the combined guide seat can be detached from both sides of the support frame without sliding to the end of the support frame before removal. During installation, the two guide seats can be inserted into the limiting edges of the support frame from both sides along the building wall at the corresponding positions, without needing to be inserted from the end of the support frame and slid to the corresponding position, greatly simplifying the difficulty of disassembly and installation. On the other hand, by setting the drive cylinder in the mounting groove between the cylinders, the cylinder bracket can have enough space on the support frame to be lifted first. After the cylinder bracket is lifted to the new working layer, the bottom combined guide seat no longer bears the load on the cylinder bracket. Therefore, the bottom combined guide seat can be removed first. Moreover, by utilizing the structure of the guide seat, it is not necessary to wait for the support frame to be fully lifted before removal, thereby saving the space and investment cost of one layer of hanging rack.

[0031] Moreover, the force-bearing points between the support frame and the combined guide seat have been changed from one to two, making the limiting between the two guide seats and the support frame more stable and the force-bearing situation better; furthermore, the weight and volume of a single guide seat are smaller than those of an integral guide seat, making it more convenient for workers to transport and use.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0041] See Figure 1 and Figure 2 This invention discloses a support column device for a formwork system, including a combined guide seat 111 connected to a building wall 7, a support frame 2 connected to the combined guide seat 111, a hydraulic cylinder bracket 3 arranged parallel to the support frame 2, and a drive cylinder 4, an upper reversing box 5, and a lower reversing box 6 connected to the hydraulic cylinder bracket 3. The combined guide seat 111 is used to guide and prevent the support frame 2 from falling. There are multiple combined guide seats 111. In this embodiment of the invention, there are three combined guide seats 111, two of which are load-bearing guide seats 11, and the bottom one is a turnover guide seat 11. The bottom guide seat 11 needs to be reinstalled on top after the formwork system is raised, serving as a new load-bearing guide seat 11 for the support frame 2 after it is raised.

[0042] Traditional guide seats 11 typically use an integral structure with an internal sleeve hole that fits over the support frame 2. During use, they need to be inserted into or removed from the support frame 2 from the end. Therefore, when the support frame 2 is raised, the guide seat 11 can only be removed after the bottom of the support frame 2 has completely left the sleeve hole. Since the hanger 10 rises together with the support frame 2, if the bottom of the support frame 2 leaves the sleeve hole, the hanger 10 corresponding to the bottom of the support frame 2 will also leave the height of the transfer guide seat 11. In order to remove the transfer guide seat 11, another hanger 10 needs to be installed below the support frame 2 to facilitate workers standing on the hanger 10 to remove the guide seat 11. In addition, the traditional hydraulic cylinder bracket 3 requires two guide seats 11 for fixation to achieve a load-bearing effect. The two guide seats 11 are respectively located at the upper and lower ends of the hydraulic cylinder bracket 3. Therefore, before removing the bottom guide seat 11, it is necessary to ensure that the hydraulic cylinder bracket 3 has been lifted and the bottom guide seat 11 no longer serves to fix the hydraulic cylinder bracket 3. The existing drive cylinder 4 is installed at the upper end of the hydraulic cylinder bracket 3. Due to the height limitation of the support frame 2, the hydraulic cylinder bracket 3 and drive cylinder 4 cannot be lifted before the support frame 2. Therefore, the lifting sequence of the traditional support column is: first lift the support frame 2 (to provide sufficient space for the lifting of the hydraulic cylinder bracket 3 and drive cylinder 4), then lift the hydraulic cylinder bracket 3 and drive cylinder 4 (so that the bottom guide seat 11 no longer serves to fix the hydraulic cylinder bracket 3), and finally remove the bottom guide seat 11.

[0043] In this embodiment of the invention, the combined guide seat 111 includes two guide seats 11 arranged opposite to each other. The two guide seats 11 are symmetrically arranged on both sides of the support frame 2, and the two guide seats 11 constitute a combined guide seat 111. Limiting edges 21 are provided on both sides of the support frame 2. The two guide seats 11 can respectively form a limiting connection with the limiting edges 21 from both sides of the support frame 2, thereby guiding the movement of the support frame 2. Due to the use of a split structure, when removing the combined guide seat 111, the two guide seats 11 can be pulled out from both sides of the support frame 2 along the building wall 7. Simultaneously, when installing the combined guide seat 111, it can be directly inserted into the limiting edges 21 on both sides of the support frame 2 along the building wall 7, making installation convenient. On the other hand, the force-bearing point between the support frame 2 and the combined guide seat 111 has changed from one to two. The two guide seats 11 and the support frame 2 are symmetrically positioned, resulting in better force distribution and greater stability. Moreover, the weight and volume of a single guide seat 11 are smaller than those of the integral guide seat 11, making it more convenient for workers to transport and use.

[0044] In addition, to enable the prior lifting of the cylinder bracket 3 and the drive cylinder 4, the cylinder bracket 3 is provided with a mounting groove 31. The drive cylinder 4 and the upper reversing box 5 are located within the mounting groove 31. The fixed end of the drive cylinder 4 is hinged to the bottom side of the mounting groove 31, and the movable end of the drive cylinder 4 is connected to the upper reversing box 5 facing upwards. The bottom of the cylinder bracket 3 is connected to the lower reversing box 6. The placement of the drive cylinder 4 within the cylinder bracket 3 significantly shortens the overall length of the drive cylinder 4 and the cylinder bracket 3. This allows the cylinder bracket 3 and the drive cylinder 4 to be lifted before the support frame 2. After the cylinder bracket 3 and the drive cylinder 4 are lifted, the bottom combined guide seat 111 can be removed without waiting for the support frame 2 to completely move away from the height of the bottom combined guide seat 111, thus saving a layer of hanging bracket 10 below the support frame 2. Moreover, by placing the lower reversing box 6 at the bottom of the cylinder bracket 3, the length of the cylinder bracket 3 can be further reduced, and the lower reversing box 6 can be avoided from occupying the space of the mounting slot 31, which facilitates the disassembly, assembly and maintenance of the drive cylinder 4 in the mounting slot 31.

[0045] The beneficial effects of the embodiments of the present invention are as follows:

[0046] The support column device for the formwork system in this embodiment of the invention includes a combined guide seat 111, a support frame 2, a hydraulic cylinder bracket 3, a drive hydraulic cylinder 4, an upper reversing box 5, and a lower reversing box 6. Traditional support column devices use an integral structure connected to the building wall 7 and the support frame 2. In this invention, the combined guide seat 111 includes two opposing guide seats 11, symmetrically arranged on both sides of the support frame 2. Each guide seat 11 has a guide wheel mechanism 12 with an installation notch 121. The installation notches 121 of the two guide seats 11 can be inserted from both sides of the support frame 2 into the limiting edge 21 of the support frame 2 to form a limiting structure. Furthermore, when used as a turnover guide seat 11, the combined guide seat 111 can be detached from both sides of the support frame 2 without sliding to... The end of the support frame 2 is then pulled out. During installation, the two guide seats 11 are inserted into the limiting edge 21 from both sides of the support frame 2 at the corresponding positions along the building wall 7. There is no need to insert them from the end of the support frame 2 and slide them to the corresponding positions, which greatly simplifies the difficulty of disassembly and installation. On the other hand, by setting the drive cylinder 4 in the mounting groove 31 between the cylinders, the cylinder bracket 3 can have enough space on the support frame 2 to be lifted first. After the cylinder bracket 3 is lifted to the new working layer, the bottom combined guide seat 111 no longer bears the load on the cylinder bracket 3. Therefore, the bottom combined guide seat 111 can be removed first. Moreover, by utilizing the structure of the guide seat 11, it is not necessary to wait for the support frame 2 to be fully lifted before removal, thereby saving the space and investment cost of one layer of hanging rack 10. Moreover, the force-bearing point between the support frame 2 and the combined guide seat 111 has changed from one to two, making the limiting between the two guide seats 11 and the support frame 2 more stable and the force-bearing situation better; furthermore, the weight and volume of a single guide seat 11 are smaller than that of an integral guide seat 11, making it more convenient for workers to transport and use.

[0047] Specifically, see Figure 3 The guide seat 11 is provided with a guide wheel mechanism 12, and the guide wheel mechanism 12 is provided with an installation notch 121. The installation notch 121 faces the limiting edge 21. The installation notches 121 of the two guide seats 11 can be inserted into the limiting edge 21 from both sides of the support frame 2 to form a limiting structure. Therefore, the guide seat 11 can be removed from both sides of the support frame 2, and can also be inserted into the limiting edge 21 from both sides of the support frame 2 to form a limiting structure.

[0048] The guide seat 11 also includes a connecting plate 111 and a guide wheel plate 112 disposed in the middle of the connecting plate 111. The connecting plate 111 is connected to the building wall 7, and the guide wheel plate 112 protrudes in a direction away from the building wall 7. The guide wheel mechanism 12 is disposed on the guide wheel plate 112. The guide wheel mechanism 12 includes a first guide wheel 122 and a second guide wheel 123. The first guide wheel 122 is rotatably disposed on the side of the guide wheel plate 112 near the connecting plate 111, and the second guide wheel 123 is rotatably disposed on the side of the guide wheel plate 112 away from the connecting plate 111. Both the first guide wheel 122 and the second guide wheel 123 protrude towards the central axis of the support frame 2. The gap between the first guide wheel 122 and the second guide wheel 123 forms the mounting notch 121, and the rolling surfaces of the first guide wheel 122 and the second guide wheel 123 can abut against the limiting edge 21. The guide wheel plates 112 are respectively disposed on the side of the limiting edge 21 away from the support frame 2, so that the support frame 2 can be restricted from the left and right sides. The first guide wheel 122 and the second guide wheel 123 are respectively located on the front and rear sides of the limiting edge 21, so that the support frame 2 can be restricted from the front and rear sides. The guide wheel mechanism 12 and the guide wheel plate 112 form a stable limit on the support frame 2, and the first guide wheel 122 and the second guide wheel 123 provide the support frame 2 with the freedom of vertical movement.

[0049] Multiple working support rods 22 protrude from both sides of the support frame 2. The working support rods 22 and the limiting edge 21 are located on the same side of the support frame 2. The multiple working support rods 22 are evenly distributed along the length of the support frame 2. A hook plate 113 is provided on the side of the guide seat 11 away from the support frame 2. The working support rods 22 can abut against the upper surface of the hook plate 113, thereby preventing the support frame 2 from moving downward and avoiding falling.

[0050] See Figure 4 The upper and lower sides of the cylinder bracket 3 are provided with support rods 32. The bottom of the support rods 32 can abut against the upper surface of the hook plate 113, thereby preventing the cylinder bracket 5 from moving downward relative to the guide seat 11.

[0051] Furthermore, both the upper reversing box 5 and the lower reversing box 6 are provided with latches. The support frame 2 has multiple lifting support rods 23 in its middle section, evenly distributed along the length of the support frame 2. Adjacent lifting support rods 23 are provided with grid holes 24, allowing the latches of the upper reversing box 5 and the lower reversing box 6 to be inserted into these grid holes 24. When the latches of the upper reversing box 5 and the lower reversing box 6 are moved downwards, the lower edge of the latch abuts against the upper edge of the lifting support rod 23 (i.e., the lower edge of the grid hole 24). At this time, the lower reversing box 6 can move upwards relative to the upper reversing box 5. When the drive cylinder 4 retracts its movable rod, it can cause the lower reversing box 6 to drive the cylinder support 3 upwards, thereby lifting the cylinder support 3. When the latches of the upper reversing box 5 and the lower reversing box 6 are moved upward, the upper edge of the latch can abut against the lower edge of the lifting support rod 23 (i.e., the upper edge of the grid hole 24). At this time, the support frame 2 and the upper reversing box 5 can move upward relative to the lower reversing box 6. When the drive cylinder 4 lifts the movable rod, it will drive the support frame 2 to move upward, thereby realizing the lifting of the support frame 2. Under the action of the latch and the hook plate 113, the support frame 2 cannot move downward relative to the upper reversing box 5 and the lower reversing box 6, thus preventing it from falling. The specific structure of the upper reversing box 5 and the lower reversing box 6 is similar to the reversing box structure commonly used in the industry, and will not be described in detail here.

[0052] See Figure 5 The present invention also discloses a construction and installation method, using the support column device for the formwork system as described above, including the following steps:

[0053] S01, bolts are pre-embedded in the building wall 7 of the working layer, and multiple combined guide seats 111 are fixed by bolts;

[0054] S02, the extension column 8 and the support frame 2 are fixedly connected on the ground with bolts, and the connected extension column 8 and the support frame 2 are lifted and installed on the combined guide seat 111;

[0055] S03, Install a top steel platform 9 on the raised column 8, and install a hanging frame 10 and a hanging frame template below the top steel platform 9;

[0056] S04, when climbing is required, first lift the cylinder bracket 3 to the new working level, then remove the bottom combined guide seat 111, and then lift the support frame 2 to the new working level by driving the cylinder 4.

[0057] S05, the two guide seats 11 included in the combined guide seat 111 are pushed from both sides of the support frame 2 along the building wall 7 to the limiting edge 21 of the support frame 2, and then the two guide seats 11 are fixed to the pre-embedded bolts with nuts.

[0058] As described above, the traditional lifting sequence of the support column is as follows: first lift the support frame 2 (to provide sufficient space for the lifting of the cylinder bracket 3 and the drive cylinder 4), then lift the cylinder bracket 3 and the drive cylinder 4 (so that the bottom guide seat 11 no longer fixes the cylinder bracket 3), and finally remove the bottom guide seat 11. In this embodiment of the invention, after the combined guide seat 111 is installed and the extension column and support frame 2 are hoisted, if it is necessary to raise the formwork system to a new working level, since the drive cylinder 4 is installed inside the cylinder bracket 3, the cylinder bracket 3 has enough space to be raised. Therefore, the cylinder bracket 3 can be raised to the new working level first. At this time, the bottom combined guide seat 111 no longer fixes the cylinder bracket 3 and can be removed. Then, the support frame 2 is raised to the new working level by the drive cylinder 4. After that, the combined guide seat 111 is divided into two guide seats 11. The two guide seats 11 are pushed from both sides of the support frame 2 along the building wall 7 to the limiting edge 21 of the support frame 2, and the two guide seats 11 are fixed to the pre-embedded bolts with nuts to form a fixed structure. With the structural improvements of the cylinder bracket 3, the drive cylinder 4, and the combined guide seat 111, as well as the improved lifting sequence of the support frame 2 and the cylinder bracket 3, the combined guide seat 111 at the bottom does not need to wait for the support frame 2 to completely leave the bottom combined guide seat 111 before it is removed. This saves on the layer of hanging bracket 10 below the support frame 2 and also facilitates disassembly and installation.

[0059] Specifically, see Figure 6 The step of first lifting the hydraulic cylinder support 3 to the new working level includes:

[0060] S41, first move the latches of both the lower reversing box 6 and the upper reversing box 5 downwards, and the movable rod of the drive cylinder 4 will be lifted upwards and drive the upper reversing box 5 to move upwards;

[0061] S42, then the movable rod of the drive cylinder 4 retracts, at which time the lower edge of the tongue buckle of the upper reversing box 5 abuts against the upper edge of the lifting support rod 23 of the support frame 2, and the drive cylinder 4 drives the cylinder bracket 3 to move upward as a whole.

[0062] S43, through repeated operations, the cylinder bracket 3 is lifted to a new working layer.

[0063] When the latches of the upper reversing box 5 and the lower reversing box 6 are moved downwards, the lower edge of the latch can abut against the upper edge of the lifting support rod 23 (i.e., the lower edge of the grid hole 24). At this time, the movable rod of the drive cylinder 4 is lifted upwards and drives the upper reversing box 5. The upper reversing box 5 can move upwards relative to the lifting support rod 23. After the movable rod is lifted to a certain height, the drive cylinder 4 drives the movable rod to retract. At this time, because the lower edge of the latch abuts against the upper edge of the lifting support rod 23 (i.e., the lower edge of the grid hole 24), the movable rod cannot move relative to the support frame 2. Under the action of the reaction force, the fixed end of the drive cylinder 4, together with the cylinder bracket 3, will be lifted upwards relative to the support frame 2, thereby realizing the overall upward movement of the cylinder bracket 3. Through repeated operations, the cylinder bracket 3 can be lifted to a new working layer.

[0064] See Figure 7 The step of removing the bottommost combined guide seat 111 includes:

[0065] S44, after the hydraulic cylinder bracket 3 is lifted to the new working level, the tongues of the upper reversing box 5 and the lower reversing box 6 are both moved upwards. The upper edge of the tongue of the upper reversing box 5 can abut against the lower edge of the lifting support rod 23 of the support frame 2. The movable rod of the driving hydraulic cylinder 4 is lifted upwards, and the upper reversing box 5 drives the support frame 2 to move upwards. The support frame 2 stops after moving a preset distance. Then, the nuts of the combined guide seat 111 are loosened, and the two guide seats 11 are removed from both sides of the support frame 2 respectively, completing the removal of the combined guide seat 111.

[0066] When the latches of the upper reversing box 5 and the lower reversing box 6 are both moved upwards, the upper edge of the latch can abut against the lower edge of the lifting support rod 23 (i.e., the upper edge of the grid hole 24). At this time, the support frame 2 and the upper reversing box 5 can move upwards relative to the lower reversing box 6, and the movable rod of the drive cylinder 4 is lifted upwards. Due to the latching action of the hook plate 113 and the support rod 32, the fixed end of the cylinder bracket 3 and the drive cylinder 4 cannot move downwards relative to the combined guide seat 111. However, since the support frame 2 can move upwards relative to the combined guide seat 111, the upper edge of the latch of the upper reversing box 5 abuts against the lower edge of the lifting support rod 23. Therefore, the movable rod of the drive cylinder 4 will drive the support frame 2 to move upwards through the upper reversing box 5. After moving a certain distance, the combined guide seat 111 can be removed. Removal is convenient as it can be taken out from both sides of the support frame 2 without sliding it to the end. In practical use, removing the combined guide seat 111 only after the support frame 2 has moved upwards a certain distance allows the support frame 2 to transfer its center of gravity and stress points to the upper and middle combined guide seats 111, thus relieving the bottom combined guide seat 111 of stress and facilitating its removal.

[0067] See Figure 8 The step of lifting the support frame 2 to the new working level by driving the hydraulic cylinder 4 includes:

[0068] S45, after the bottommost combined guide seat 111 is removed, the movable rod of the drive cylinder 4 continues to lift upward and drive the upper reversing box 5 to move upward. The upper edge of the tongue buckle of the upper reversing box 5 can abut against the lower edge of the lifting support rod 23 of the support frame 2. The upper reversing box 5 drives the support frame 2 to move upward.

[0069] S46, then the movable rod of the drive cylinder 4 retracts, at which time the upper edge of the tongue buckle of the lower reversing box 6 abuts against the lower edge of the lifting support rod 23 of the support frame 2 to prevent the support frame 2 from falling;

[0070] S47, through repeated operations, the support frame 2 is raised to a new working level.

[0071] During this process, the latches of both the upper reversing box 5 and the lower reversing box 6 remain facing upwards. The upper reversing box 5 can continuously drive the support frame 2 to move upwards. After one lifting, the movable rod of the drive cylinder 4 retracts. However, because the upper edge of the latch of the lower reversing box 6 abuts against the lower edge of the lifting support rod 23 of the support frame 2, the support frame 2 cannot fall. Then, the movable rod of the drive cylinder 4 continues to lift, and the support frame 2 continues to rise until it is lifted to a new working layer.

[0072] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
