Abstract

This application relates to a box-type transverse plate support device, belonging to the field of support structure technology. It includes two support plates. The two support plates are respectively abutted against opposite side walls of a trench. Each support plate is provided with a connecting component. A mounting frame is vertically installed in the trench, located on the central axis of the trench. A driving component is located at the center of the mounting frame, and the driving component can rotate on the mounting frame. The end of the connecting component away from the support plate is connected to the driving component, wherein the connecting component can drive the support plate to move closer to or away from the mounting frame. That is, during installation, rotating the driving component causes the connecting component to move the support plate parallel to the side wall of the trench.

This application has the advantage of convenient operation in abutting the support plate against the side wall of the trench.

Description

Technical Field

[0001] This application relates to the field of support structures, and in particular to a box-type transverse plate support device. Background Technology

[0002] There are many trench support methods in the field of urban municipal utility pipeline trenching and laying. Timber trench support is one of the more commonly used construction methods, especially for trenches with an excavation depth of less than 3 meters, and its application is also quite widespread.

[0003] In the related technology, Chinese patent with publication number CN114687362A discloses a box-type trench support structure and support method, including a horizontal strut, with telescopic screws threaded to the left and right sides of the horizontal strut, each telescopic screw being hinged to a support seat, the support seat being slidably set in a groove and locked by a fixing pin, the left and right grooves being respectively installed on a force plate, and the two force plates forming a support for the trench soil.

[0004] In use, after the load-bearing plate is hoisted into the trench using lifting equipment, the length of the horizontal support rod is changed by adjusting the telescopic screw to match the width of the trench. After adjustment, the support seats on the two load-bearing plates are fixed with multiple fixing pins. That is, when installing the load-bearing plate in the trench, it is necessary to tighten the telescopic screw and install multiple fixing pins, which is cumbersome and needs to be improved. Summary of the Invention

[0005] To address the inconvenience of installing load-bearing plates in trenches, this application provides a box-type transverse plate support device.

[0006] The box-type transverse plate support device provided in this application adopts the following technical solution:

[0007] A box-type transverse plate support device for supporting trenches, comprising:

[0008] Mounting bracket, located in the trench;

[0009] Two support plates are vertically installed and abut against the two opposite sidewalls of the trench. The two support plates are arranged symmetrically about the central axis of the mounting frame. The support plates are connected to the mounting frame through connecting components.

[0010] A drive assembly is disposed on the mounting frame and connected to the connecting assembly. The drive assembly is used to drive the two connecting assemblies to rotate about the central axis of the mounting frame, and can drive the connecting assemblies to move the support plate away from the mounting frame.

[0011] By adopting the above technical solution, during use, the mounting bracket is placed vertically in the trench and located on the central axis of the trench. In the initial state, the two support plates are parallel and perpendicular to the sidewall of the trench. Then, the drive assembly is started, which drives the two connecting components to rotate around the central axis of the mounting bracket, so that the support plates rotate 90°, that is, parallel to the sidewall of the trench. Then, the drive assembly continues to move, thereby pushing the connecting components to move away from the mounting bracket, so that the support plates are pressed against the inner wall of the trench, thus supporting the trench. The operation is convenient.

[0012] During disassembly, the drive assembly is reset, causing the connecting assembly to move the support plate closer to the mounting bracket, separating the support plate from the trench sidewall. The connecting assembly then rotates the support plate until it is perpendicular to the trench sidewall. At this point, the mounting bracket is moved upwards until the support plate is out of the trench, completing the disassembly process. After the support plate rotates to be perpendicular to the inner wall of the trench, the distance from the support plate to the trench is longer than when the support plate is parallel to the trench sidewall. This increases the range of movement of the support plate in the trench width direction when the mounting bracket moves the support plate up and down within the trench, making it less likely to damage the trench structure during installation and disassembly.

[0013] Optionally, the driving component includes:

[0014] The mounting tube is vertically arranged on the central axis of the mounting frame and is rotatably connected to the mounting frame. A spiral groove is formed on the side wall of the mounting tube, and a moving groove is formed on the side wall of the mounting tube in the vertical direction. The top end of the moving groove is connected to the bottom end of the spiral groove. The connecting components are provided on the mounting tube, and the two connecting components are arranged symmetrically about the central axis of the mounting tube.

[0015] A movable rod is inserted into the mounting tube and driven by a drive component to move up and down within the mounting tube. The drive component is mounted on the mounting frame, and its output end is fixed to the movable rod. A sliding rod is fixed to the side wall of the movable rod. The sliding rod can be inserted into and move within the spiral groove to drive the mounting tube to rotate. The sliding rod can also be inserted into and move within the movable slot.

[0016] By adopting the above technical solution, after the mounting bracket is placed on the central axis of the trench, the drive unit is activated, driving the moving rod to move in the mounting tube, causing the sliding rod to move in the spiral groove. The inner wall of the spiral groove abuts against the side wall of the sliding rod, restricting and guiding the sliding rod, so that the sliding rod can only move along the trajectory of the spiral groove. The sliding rod moves vertically along with the moving rod, thus pushing the inner wall of the spiral groove to move during the movement. That is, the sliding rod moves relative to the inner wall of the spiral groove, causing the mounting tube to rotate. This drives the two connecting components to rotate the corresponding support plate around the mounting tube as an axis. When the support plate rotates to be parallel to the side wall of the trench, the sliding rod also moves to the bottom of the spiral groove and enters the moving groove. Then the moving rod continues to move, causing the sliding rod to move in the moving groove, thus fixing the state of the mounting tube and preventing further rotation. That is, the support plate maintains a state parallel to the side wall of the trench, thereby increasing the stability of the support plate against the side wall of the trench.

[0017] Optionally, the connection component includes:

[0018] A connecting rod is horizontally arranged. One end of the connecting rod is inserted into the mounting tube and can move in the mounting tube towards or away from the central axis of the mounting tube. The other end is connected to the corresponding support plate. The end of the connecting rod near the central axis of the mounting tube is provided with a guide surface. When the moving rod abuts against the guide surface, it is used to drive the connecting rod to move away from the central axis of the mounting tube.

[0019] A connecting spring is disposed in the mounting tube. One end of the connecting spring is fixed to the inner wall of the mounting tube, and the other end is fixed to the connecting rod, which is used to drive the connecting rod to move in a direction close to the central axis of the mounting tube.

[0020] By adopting the above technical solution, when the moving rod moves down in the installation tube and the sliding rod enters the moving groove from the spiral groove, the support plate rotates to be parallel to the side wall of the trench. The moving rod continues to move down. When the bottom end of the moving rod abuts against the guide surface, the guide surface plays a guiding role, causing the bottom end of the moving rod to slide relative to the guide surface. This causes the connecting rod to move away from the central axis of the installation tube, compressing the connecting spring and pushing the support plate to move towards the side wall of the trench. When the moving rod moves past the guide surface, the connecting rod, under the action of the connecting spring, causes the end of the connecting rod near the installation tube to abut against the side wall of the moving rod. At this time, the support plate is pressed against the side wall of the trench, thus providing a support for the trench.

[0021] During disassembly, the driving component moves the moving rod upward. When the moving rod passes the connecting rod, the connecting spring returns to its original deformation, causing the connecting rod to move the support plate closer to the mounting pipe. This creates a gap between the support plate and the trench sidewall, allowing the mounting pipe to rotate the support plate so that it is perpendicular to the trench sidewall. This facilitates the removal of the support plate from the trench, completing the disassembly.

[0022] Optionally, the connecting rod includes:

[0023] A positioning rod is horizontally positioned, with one end inserted into the mounting tube. A guide surface is provided on the positioning rod, and a connecting spring is connected to the positioning rod.

[0024] A push rod is horizontally positioned and slidably connected to the positioning rod. The end of the push rod away from the positioning rod is fixedly connected to the support plate. A sliding block is fixedly connected to the push rod. A clamping assembly is provided on the positioning rod. The clamping assembly is connected to the sliding block and is used to drive the sliding block to move towards or away from the installation tube.

[0025] By adopting the above technical solution, when the sliding rod moves down into the moving groove and moves within it, the support plate is parallel to the sidewall of the trench. During the movement of the sliding rod, its end first abuts against the guide surface on the positioning rod, thereby pushing the positioning rod to move away from the central axis of the installation tube and driving the push rod to move, thus causing the support plate to move towards the sidewall of the trench. Then, the sliding rod continues to move down, causing the clamping assembly to move, driving the sliding block to move the push rod away from the central axis of the installation tube until the support plate is pressed against the sidewall of the trench. At this point, the clamping assembly pushes the sliding block to move while simultaneously restricting its return to its original position, thereby increasing the stability of the support plate pressed against the sidewall of the trench. Furthermore, the distance between the support plates is adjustable to accommodate trenches of different widths, offering good applicability.

[0026] Optionally, the clamping component includes:

[0027] A transmission belt is provided on the positioning rod. The transmission belt includes a driving wheel, a driven wheel, and a conveyor belt. The driving wheel is located in the mounting tube. The driving wheel and the driven wheel are on the same horizontal line, and both the driving wheel and the driven wheel are rotatably connected to the side wall of the positioning rod. The conveyor belt passes through the side wall of the mounting tube and is sleeved on the driving wheel and the driven wheel. The driving wheel rotates to drive the conveyor belt to move. The sliding block is fixedly connected to the side wall of the conveyor belt.

[0028] A rotating gear is disposed inside the mounting tube, and the rotating gear is coaxially fixed on the driving wheel;

[0029] A rotating rack is vertically mounted in the mounting tube. The rotating rack is slidably connected to the positioning rod and meshes with the rotating gear. An annular groove is formed on the side wall of the moving rod, and a push block that can move in the annular groove is inserted in the annular groove. A push groove is formed on the side wall of the rotating rack in the vertical direction, and the push block is inserted in the push groove and can move in the push groove.

[0030] By adopting the above technical solution, when the moving rod moves downward in the mounting tube under the drive of the driving component, the driving mounting tube drives the positioning rod to rotate, and the inner wall of the propulsion groove abuts against the side wall of the propulsion block, thereby pushing the propulsion block to rotate with the rotation of the mounting rod, so that the propulsion block moves in the annular groove. When the sliding rod is inserted into the moving groove, it causes the propulsion block to move in the propulsion groove. The rotating rack itself is relatively light, and the rotating gear increases the resistance to the rotating rack, so it cannot move downward by its own weight. When the moving rod passes the positioning rod, the propulsion block also moves to the bottom of the propulsion groove, so that the propulsion block can push the rotating rack to move downward, drive the rotating gear to rotate, so that the drive wheel rotates and drives the conveyor belt to move, so that the push rod moves on the positioning rod, so that the push rod drives the support plate to move away from the positioning rod, that is, the two support plates move simultaneously, so that the distance between the two support plates meets the grooves of different widths, until the support plate abuts against the side wall of the groove, thus achieving support for grooves of different widths and improving applicability.

[0031] Optionally, an extension assembly is connected to the support plate, the extension assembly comprising:

[0032] An extension plate is vertically disposed on one side of the support plate. A mounting hole is provided on one side wall of the support plate. The extension plate is inserted into the mounting hole and can move in the mounting hole in a direction perpendicular to the push rod. Several slots are horizontally provided on the side of the support plate away from the mounting tube. Several abutment rods that can be inserted into the slots and can move in the slots are fixed horizontally on the side wall of the extension plate away from the mounting tube.

[0033] A telescopic rod is parallel to the positioning rod, the telescopic rod is located between the two extension plates, and both ends of the telescopic rod are fixed to the two extension plates respectively.

[0034] By adopting the above technical solution, when the push rod pushes the support plate to move away from the installation pipe, the extension plate also moves accordingly, thereby increasing the distance between the two extension plates. This means the telescopic rod is lengthened to meet the distance requirement between the two extension plates, ensuring they are always connected by the telescopic rod. Once the support plate is parallel to and abuts against the sidewall of the trench, the telescopic rod is manually driven to move parallel away from the installation pipe, causing both extension plates to extend out of the installation hole simultaneously. During this process, the abutting rod is pulled out of the slot and directly abuts against the sidewall of the trench, filling the gap between the extension plate and the trench sidewall. The side of the abutting rod that abuts against the trench sidewall and the side of the support plate that abuts against the trench sidewall are in the same plane, allowing the portion of the extension plate extending out of the support plate to also support the trench sidewall.

[0035] Optionally, the telescopic rod includes:

[0036] The mounting sleeve is horizontally positioned, with one end fixedly connected to one of the extension plates. A fixing hole is provided through the side wall of the mounting sleeve, located at the opening of the mounting sleeve.

[0037] A mounting rod is horizontally inserted into the mounting sleeve, and one end of the mounting rod away from the mounting sleeve is fixedly connected to another extension plate.

[0038] A fixing bolt passes through the fixing hole and is threaded into the fixing hole. One end of the fixing bolt located inside the mounting sleeve can abut against the side wall of the mounting rod to fix the mounting rod in the mounting sleeve.

[0039] By adopting the above technical solution, when the two support plates move simultaneously away from the installation pipe, the installation rod extends out of the installation sleeve, making the overall length of the telescopic rod longer to accommodate the distance between the two support plates. Then, the fixing bolt is adjusted towards the installation rod so that the end of the fixing bolt abuts against the installation rod, applying a compressive force to the installation rod, thereby fixing the installation rod in the installation sleeve. That is, the length of the telescopic rod is fixed, which provides support and fixation for the extension plate and increases the stability of the abutment rod on the extension plate against the trench sidewall.

[0040] Optionally, a fixing rod is vertically provided in the mounting hole. The fixing rod is rotatably connected to the inner wall of the mounting hole. Several sealing strips for inserting into the slot to seal the slot are wound around the fixing rod. One end of the sealing strip is fixed to the end of the abutment rod near the end wall of the slot, and the other end is fixed to the fixing rod.

[0041] By adopting the above technical solution, when the abutment rod moves in the slot, one end of the abutment rod drives the sealing strip to move, and at the same time causes the fixing rod to rotate, so that the sealing strip can be released from the fixing rod. This allows the sealing strip to block the distance between the end of the abutment rod and the end wall of the slot. That is, the abutment rod and the sealing strip work together to seal the entire slot, so that the soil on the trench is not easy to get stuck in the slot and affect the movement of the abutment rod.

[0042] Optionally, a plurality of fixing blocks are fixed on the side of the sealing strip near the installation pipe, and the plurality of fixing blocks are arranged at intervals along the length of the sealing strip.

[0043] By adopting the above technical solution, the fixing blocks are arranged at intervals, which will not affect the sealing strip being rolled and stored on the fixing rod. The fixing blocks increase the stability of the sealing strip structure and make it less prone to bending and breakage.

[0044] Optionally, the inner wall of the mounting hole is provided with a receiving hole, one end of the fixing rod is rotatably connected to the inner wall of the mounting hole, and the other end of the fixing rod is inserted into the receiving hole and rotatably connected to the inner wall of the receiving hole. A coil spring is provided in the receiving hole, one end of the coil spring is fixed to the inner wall of the receiving hole, and the other end is fixed to the fixing rod. A limiting rack is provided in the mounting hole, one end of the limiting rack extends out of the mounting hole, and a limiting block is fixed on the side wall of the limiting rack. A limiting hole is provided in the inner wall of the mounting hole in the vertical direction, and the limiting block is inserted into the limiting hole and can move in the limiting hole. A limiting tooth groove is provided on the side wall of the extension plate for the limiting rack to be inserted.

[0045] By adopting the above technical solution, after the extension plate extends out of the mounting hole, the limiting rack is moved closer to the extension plate until it is properly inserted into the limiting tooth groove. The side wall of the upper tooth of the limiting rack abuts against the inner wall of the limiting tooth groove, thus restricting the extension plate from moving further, and fixing the length of the extension plate extending out of the mounting hole. When disassembly is required, the limiting rack is moved away from the extension plate, causing it to be pulled out of the limiting tooth groove. The fixing rod rotates under the action of the coil spring, causing the sealing strip to rewind onto the fixing rod, thereby driving the abutment rod back into the slot, realizing the reset of the extension plate. This shortens the overall length of the support plate and the extension plate, making it easier for the mounting tube to rotate the support plate and achieve disassembly.

[0046] In summary, this application includes at least one of the following beneficial effects:

[0047] 1. When in use, place the mounting bracket vertically in the trench and on the central axis of the trench. In the initial state, the two support plates are parallel and perpendicular to the side wall of the trench. Then, start the drive assembly, which drives the two connecting components to rotate around the central axis of the mounting bracket, so that the support plates rotate 90°, that is, parallel to the side wall of the trench. Then the drive assembly continues to move, thereby pushing the connecting components to move away from the mounting bracket, so that the support plates are pressed against the inner wall of the trench, thus supporting the trench.

[0048] 2. After the mounting bracket is placed on the central axis of the trench, the drive unit is activated, driving the moving rod to move in the mounting tube. This causes the sliding rod to push the inner wall of the spiral groove to move, i.e., the sliding rod moves relative to the inner wall of the spiral groove, causing the mounting tube to rotate. This drives the two connecting components to rotate the corresponding support plate around the mounting tube as an axis. When the support plate rotates to be parallel to the side wall of the trench, the sliding rod also moves to the bottom of the spiral groove and enters the moving groove. Then the moving rod continues to move, causing the sliding rod to move in the moving groove, thereby fixing the state of the mounting tube and preventing further rotation. That is, the support plate maintains a state parallel to the side wall of the trench, thereby increasing the stability of the support plate against the side wall of the trench.

[0058] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0059] This application discloses a box-type transverse plate support device. (Refer to...) Figure 1 and Figure 2The box-type transverse plate support device includes two support plates 40. The two support plates 40 are respectively abutted against the opposite side walls of the trench 110. Each support plate 40 is equipped with a connecting component 30. A mounting frame 10 is vertically installed in the trench 110, located on the central axis of the trench 110. A drive component 20 is located at the center of the mounting frame 10, allowing it to rotate. The end of the connecting component 30 away from the support plate 40 is connected to the drive component 20, enabling the connecting component 30 to move the support plate 40 towards or away from the mounting frame 10. During installation of the box-type transverse plate support device, rotating the drive component 20 causes the connecting component 30 to move the support plate 40 parallel to the side wall of the trench 110. Then, both connecting components 30 are simultaneously driven to move away from the mounting frame 10, thereby abutting the support plate 40 against the corresponding side wall of the trench 110, thus supporting the trench 110.

[0060] Reference Figure 1 and Figure 2 The drive assembly 20 includes a mounting tube 21 and a moving rod 22. The mounting tube 21 is vertically arranged on the central axis of the mounting frame 10. The bottom end of the mounting tube 21 is rotatably connected to the mounting frame 10. A spiral groove 211 is provided through the side wall of the mounting tube 21. The spiral groove 211 is spiral in shape and occupies half the circumference of the mounting tube 21. A moving groove 212 is provided through the side wall of the mounting tube 21 in the vertical direction. The top end of the moving groove 212 is connected to the bottom end of the spiral groove 211. The connecting assembly 30 is provided on the mounting tube 21, and the two connecting assemblies 30 are arranged symmetrically about the central axis of the mounting tube 21.

[0061] Reference Figure 1 and Figure 2 The moving rod 22 is vertically arranged and inserted into the mounting tube 21 through the top opening of the mounting tube 21. The moving rod 22 can move up and down within the mounting tube 21. A driving component 23 is fixed to the mounting bracket 10 by bolts. In this embodiment, the driving component 23 is an electric push rod. The output end of the driving component 23 faces downward and is fixedly connected to the top end of the moving rod 22 for driving the moving rod 22 to move up and down. A horizontal sliding rod 221 is fixed on the side wall of the moving rod 22. The sliding rod 221 can be inserted into the spiral groove 211 or the moving groove 212 and move within the spiral groove 211 or the moving groove 212.

[0062] In the initial state, the two support plates 40 are parallel and perpendicular to the sidewalls of the trench 110, and the sliding rod 221 is located at the top of the spiral groove 211. Then, the drive unit 23 is activated, driving the moving rod 22 to move in the mounting tube 21, so that the sliding rod 221 moves in the spiral groove 211. The sliding rod 221 always moves vertically along with the moving rod 22, so that the sliding rod 221 pushes the inner wall of the spiral groove 211 to move during the movement, that is, the sliding rod 221 moves relative to each other in the spiral groove 211, causing the mounting tube 21 to rotate, driving the two connecting components 30 to drive the corresponding support plates 40 to rotate around the mounting tube 21 as the axis. When the support plate 40 rotates to be parallel to the side wall of the trench 110, the sliding rod 221 also moves to the bottom of the spiral groove 211 and enters the moving groove 212. Then the moving rod 22 continues to move, so that the sliding rod 221 moves in the moving groove 212, thereby fixing the state of the installation pipe 21 and preventing it from rotating. That is, the support plate 40 maintains a state parallel to the side wall of the trench 110, thereby increasing the stability of the support plate 40 against the side wall of the trench 110.

[0063] Reference Figure 2 and Figure 3 The connecting assembly 30 includes a connecting rod 31 and a connecting spring 32. The connecting rod 31 is horizontally arranged and includes a positioning rod 311 and a pushing rod 312. The positioning rod 311 is horizontally arranged and one end is inserted into the mounting tube 21 and can move horizontally. A guide surface 314 is cut on the top wall of the positioning rod 311. The guide surface 314 is located on the end of the positioning rod 311 inserted into the mounting tube 21. The end of the guide surface 314 near the central axis of the mounting tube 21 is inclined downward. One end of the connecting spring 32 is fixedly connected to the inner wall of the mounting tube 21, and the other end is fixedly connected to the positioning rod 311 through a positioning plate. Under the action of the corresponding connecting spring 32, the two positioning rods 311 are brought close to each other and abut against each other. A guide block is integrally formed on the push rod 312. A guide groove is formed on the positioning rod 311 along the length direction of the positioning rod 311. The guide block is inserted into the guide groove and can move in the guide groove. A sliding block 313 is fixed on the side wall of the push rod 312. A clamping component 50 is provided on the side wall of the positioning rod 311. The clamping component 50 is connected to the sliding block 313. The clamping component 50 is used to drive the sliding block 313 to move the push rod 312 toward or away from the mounting tube 21.

[0064] When the moving rod 22 moves down in the mounting tube 21 and the sliding rod 221 enters the moving groove 212 through the spiral groove 211, the support plate 40 rotates to be parallel to the side wall of the groove 110. The moving rod 22 continues to move down. When the bottom end of the moving rod 22 abuts against the guide surface 314, the guide surface 314 plays a guiding role, causing the bottom end of the moving rod 22 to slide relative to the guide surface 314. This causes the positioning rod 311 to move away from the central axis of the mounting tube 21, compressing the connecting spring 32 and driving the push rod 312 to push the support plate 40 towards the side wall of the groove 110. When the moving rod 22 moves past the guide surface 314, the positioning rod 311, under the action of the connecting spring 32, causes the end of the positioning rod 311 near the mounting tube 21 to abut against the side wall of the moving rod 22. At this time, the support plate 40 abuts against the side wall of the groove 110.

[0065] Reference Figure 2 and Figure 4 The clamping assembly 50 includes a transmission belt 51, a rotating gear 53, and a rotating rack 52. The transmission belt 51 is mounted on the positioning rod 311 and includes a driving wheel 511, a driven wheel 512, and a conveyor belt 513. The driving wheel 511 and the driven wheel 512 are rotatably connected to the positioning rod 311 via a rotating shaft and are located on the same horizontal line. The driving wheel 511 is located in the mounting tube 21. The conveyor belt 513 passes through the side wall of the mounting tube 21 and is sleeved on the driving wheel 511 and the driven wheel 512. The sliding block 313 is fixedly connected to the side wall of the conveyor belt 513. The rotating gear 53 is coaxially fixed on the driving wheel 511, that is, fixedly sleeved on the rotating shaft connected to the driving wheel 511. The rotating rack 52 is vertically mounted in the mounting tube 21.

[0066] Reference Figure 4 and Figure 5 A connecting block is integrally formed on the side wall of the rotating rack 52. A connecting groove is formed on the side wall of the positioning rod 311 along the vertical direction. The connecting block is inserted into the connecting groove and can move in the connecting groove, so that the rotating rack 52 is slidably connected to the positioning rod 311 in the vertical direction. The rotating rack 52 meshes with the rotating gear 53. An annular groove 222 is formed on the side wall of the moving rod 22. A push block 223 is inserted into the annular groove 222 and can move in the annular groove 222. A push groove 521 is formed on the side wall of the rotating rack 52 along the vertical direction. The push block 223 is inserted into the push groove 521 and can move in the push groove 521.

[0067] When the moving rod 22 moves downward in the mounting tube 21 under the drive of the driving member 23, the driving mounting tube 21 drives the positioning rod 311 to rotate, and the inner wall of the pushing groove 521 abuts against the side wall of the pushing block 223, thereby pushing the pushing block 223 to rotate with the rotation of the mounting rod 622, so that the pushing block 223 moves in the annular groove 222. When the sliding rod 221 is inserted in the moving groove 212, the pushing block 223 moves in the pushing groove 521. The rotating rack 52 itself is relatively light, and the rotating gear 53 increases the resistance to the rotating rack 52, so it cannot move downward by its own weight. At the same time, when the positioning rod 311 drives the push rod 312 to push the support plate 40 against the side wall of the groove 110, the groove 110 restricts the movement of the support plate 40, thereby pushing the rod on the positioning rod 311 to move closer to the mounting tube 21, thereby causing the sliding block 313 to drive the conveyor belt 513 to move, causing the drive wheel 511 to drive the rotating gear 53 to rotate, thereby driving the rotating rack 52 to move upward, further ensuring that the rotating rack 52 will not move downward during this process.

[0068] Reference Figure 1 and Figure 4 When the moving rod 22 passes the positioning rod 311, the pushing block 223 also moves to the bottom of the pushing groove 521, so that the pushing block 223 can push the rotating rack 52 down and drive the rotating gear 53 to rotate, so that the driving wheel 511 rotates and drives the conveyor belt 513 to move, so that the pushing rod 312 moves on the positioning rod 311, so that the pushing rod 312 drives the support plate 40 to move away from the positioning rod 311, that is, the two support plates 40 move at the same time, so that the distance between the two support plates 40 meets the grooves 110 of different widths, until the support plates 40 are pressed against the side wall of the groove 110, thus achieving support for the grooves 110 of different widths.

[0069] During disassembly, the driving component 23 moves the moving rod 22 upward. When the moving rod 22 passes the positioning rod 311, the connecting spring 32 returns to its original deformation, causing the positioning rod 311 to drive the push rod 312 to move closer to the central axis of the mounting tube 21. At the same time, the moving rod 22 also drives the pushing block 223 to move to the top of the pushing groove 521 and pushes the rotating rack 52 upward, causing the sliding block 313 to drive the push rod 312 to move further closer to the mounting tube 21. This causes the push rod 312 to drive the support plate 40 to move until there is a gap between the support plate 40 and the side wall of the groove 110, which facilitates the mounting tube 21 to drive the support plate 40 to rotate, making the support plate 40 perpendicular to the side wall of the groove 110, making it easier to pull the support plate 40 out of the groove 110 and complete the disassembly.

[0070] Reference Figure 6 and Figure 7In order to enable the support plate 40 to support a larger area of ​​the trench 110, an extension component 60 is provided on each support plate 40. The extension component 60 includes an extension plate 61, which is vertically arranged. When the support plate 40 is parallel to the side wall of the trench 110, a mounting hole 41 is opened on one side wall of the support plate 40 in the length direction of the trench 110. The extension plate 61 is inserted into the mounting hole 41 and can move in the mounting hole 41 in a direction perpendicular to the push rod 312. Several slots 42 are horizontally opened on the side of the support plate 40 away from the mounting tube 21. Several abutment rods 611 are integrally formed on the side wall of the extension plate 61 away from the mounting tube 21 in the horizontal direction. The abutment rods 611 are horizontally arranged and each abutment rod 611 is inserted into the corresponding slot 42 and can move in the slot 42.

[0071] When the support plate 40 is parallel to and abuts against the side wall of the trench 110, the two extension plates 61 are manually driven to extend out of the mounting holes 41 at the same time. During this process, the abutment rod 611 is pulled out of the slot 42 and directly abuts against the side wall of the trench 110 to fill the gap between the extension plate 61 and the side wall of the trench 110. The side of the abutment rod 611 that abuts against the side wall of the trench 110 and the side of the support plate 40 that abuts against the side wall of the trench 110 are in the same plane, so that the part of the extension plate 61 that extends out of the support plate 40 can also support the side wall of the trench 110.

[0072] Reference Figure 6 and Figure 7 To improve the synergy between the two extension plates 61, i.e., to ensure equal support areas on both sides of the trench 110, a telescopic rod 62 is provided between the two extension plates 61. The telescopic rod 62 is horizontally positioned and includes a mounting sleeve 621, a mounting rod 622, and a fixing bolt 623. The mounting sleeve 621 is horizontally positioned, and one end of the mounting sleeve 621 is fixedly connected to one of the extension plates 61. The mounting rod 622 is inserted into the mounting sleeve 621, and one end of the mounting rod 622 extends out of the other end of the mounting sleeve 621 and is fixedly connected to the other extension plate 61. A fixing hole 624 is provided through the side wall of the mounting sleeve 621. The fixing bolt 623 passes through the fixing hole 624 and is threadedly connected to the fixing hole 624. One end of the fixing bolt 623 can abut against the side wall of the mounting rod 622 to fix the mounting rod 622 in the mounting sleeve 621.

[0073] When the two support plates 40 move simultaneously away from the mounting pipe 21, the mounting rod 622 extends out of the mounting sleeve 621, making the overall length of the telescopic rod 62 longer to accommodate the distance between the two support plates 40. Then, the fixing bolt 623 is adjusted towards the mounting rod 622 so that the end of the fixing bolt 623 abuts against the mounting rod 622, applying a compressive force to the mounting rod 622, thereby fixing the mounting rod 622 in the mounting sleeve 621. That is, the length of the telescopic rod 62 is fixed, which provides support and fixation for the extension plate 61, increasing the stability of the abutment rod 611 on the extension plate 61 against the side wall of the trench 110.

[0074] Reference Figure 6 and Figure 7 A fixing rod 70 is vertically installed in the mounting hole 41. A receiving hole 411 is provided on the inner wall of the mounting hole 41. One end of the fixing rod 70 is inserted into the receiving hole 411 and rotatably connected to the inner wall of the receiving hole 411, while the other end of the fixing rod 70 is rotatably connected to the inner wall of the mounting hole 411. A coil spring 71 is provided in the receiving hole 411. One end of the coil spring 71 is fixed to the inner wall of the receiving hole 411, and the other end is fixed to the fixing rod 70.

[0075] Reference Figure 6 and Figure 7 Several sealing strips 80 are wound around the fixing rod 70. Each sealing strip 80 can be fitted into a corresponding slot 42 to seal the slot 42. One end of the sealing strip 80 is fixed to the end of the abutment rod 611 near the end wall of the slot 42, and the other end is fixed to the fixing rod 70. To increase the stability of the sealing strip 80 structure, several fixing blocks 81 are fixed on the side of the sealing strip 80 near the mounting tube 21. The fixing blocks 81 are arranged at intervals along the length of the sealing strip 80.

[0076] When the abutment rod 611 moves in the slot 42, one end of the abutment rod 611 drives the sealing strip 80 to move, and at the same time causes the fixing rod 70 to rotate, allowing the sealing strip 80 to be released from the fixing rod 70. This allows the sealing strip 80 to seal the distance between the end of the abutment rod 611 and the end wall of the slot 42. In other words, the abutment rod 611 and the sealing strip 80 cooperate to seal the entire slot 42, making it difficult for soil on the trench 110 to get stuck in the slot 42 and affect the movement of the abutment rod 611. When the extension plate 61 is reinserted into the mounting hole 41, the abutment rod 611 pushes the sealing strip 80 to reset, and the coil spring 71 causes the fixing rod 70 to rotate, making it easy for the sealing strip 80 to rewind onto the fixing rod 70.

[0077] Reference Figure 7 and Figure 8To prevent the coil spring 71 from driving the fixed rod 70 to rotate and thus driving the sealing strip 80 to retract, causing the abutment rod 611 to move, a limiting rack 90 is provided in the mounting hole 41. The limiting rack 90 is located above the extension plate 61, with one end of the limiting rack 90 extending out of the mounting hole 41. A limiting block 91 is fixed on the side wall of the limiting rack 90. ​​A limiting hole 412 is opened vertically on the inner wall of the mounting hole 41. The limiting block 91 is inserted into the limiting hole 412 and can move within the limiting hole 412. A limiting tooth groove 612 is opened on the side wall of the extension plate 61 for the limiting rack 90 to be inserted. To increase the stability of the limiting rack 90 inserted in the limiting tooth groove 612, a limiting spring 911 is provided in the limiting hole 412. One end of the limiting spring 911 is fixed to the inner top wall of the limiting hole 412, and the other end is fixed to the limiting rack 90, which is used to press the limiting rack 90 downward.

[0078] After the extension plate 61 extends out of the mounting hole 41, the limiting rack 90 is moved closer to the extension plate 61 until it is properly inserted into the limiting tooth groove 612. The side wall of the upper tooth of the limiting rack 90 abuts against the inner wall of the limiting tooth groove 612, thus limiting the extension plate 61 and preventing it from moving further. In other words, the length of the extension plate 61 extending out of the mounting hole 41 is fixed. When disassembly is required, the limiting rack 90 is moved away from the extension plate 61, causing it to be withdrawn from the limiting tooth groove 612. The fixing rod 70 rotates under the action of the coil spring 71, causing the sealing strip 80 to rewind onto the fixing rod 70. This causes the abutment rod 611 to be inserted back into the slot 42, resetting the extension plate 61. This shortens the overall length of the support plate 40 and the extension plate 61, making it easier for the mounting tube 21 to rotate the support plate 40, thus facilitating disassembly.

[0079] The implementation principle of the box-type horizontal plate support device in this application embodiment is as follows: In use, the mounting frame 10 is placed vertically in the trench 110 and located on the central axis of the trench 110. In the initial state, the two support plates 40 are parallel and perpendicular to the side wall of the trench 110. Then, the drive assembly 20 is started, which drives the two connecting assemblies 30 to rotate around the central axis of the mounting frame 10, so that the support plates 40 rotate 90°, that is, parallel to the side wall of the trench 110. Then, the drive assembly 20 continues to move, thereby pushing the connecting assemblies 30 to move away from the mounting frame 10, so that the support plates 40 are pressed against the inner wall of the trench 110, thereby supporting the trench 110. The operation is convenient.

[0080] During disassembly, the drive assembly 20 is reset, causing the connecting assembly 30 to move the support plate 40 closer to the mounting bracket 10, thus separating the support plate 40 from the side wall of the trench 110. Then, the connecting assembly 30 rotates the support plate 40 until it is perpendicular to the side wall of the trench 110. At this point, the mounting bracket 10 is moved upwards until the support plate 40 moves out of the trench 110, completing the disassembly. After the support plate 40 rotates to be perpendicular to the inner wall of the trench 110, the distance from the support plate 40 to the trench 110 is longer than when the support plate 40 is parallel to the side wall of the trench 110. This increases the movement margin of the support plate 40 in the width direction of the trench 110 when the mounting bracket 10 moves the support plate 40 up and down within the trench 110, making it less likely to damage the structure of the trench 110 during installation and disassembly.

[0081] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
