Abstract
Description
Technical Field
[0001] This invention relates to the field of formwork support technology in building construction, and specifically to a matrix-type self-locking telescopic support system. Background Technology
[0002] Cast-in-place concrete structures are the core construction method in current building construction projects, and the formwork support system is a key link in ensuring the quality of concrete pouring and construction safety. Currently, the construction industry commonly uses steel pipe coupler type and disc-lock type full-span support frames as formwork support structures for floor slabs and beams. These support systems are all constructed manually, one by one, from loose steel pipes, couplers, and crossbars.
[0003] However, the conventional formwork support structure erection process is cumbersome and time-consuming. The erection of the structure is highly dependent on manual labor, which can easily lead to problems such as missing parts, loose fasteners, and deviations in the verticality of the uprights.
[0004] Therefore, there is an urgent need to propose an integrated, modular support system to achieve rapid and automatic frame formation, significantly reduce reliance on manual labor, and shorten the construction cycle. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention proposes a matrix-type self-locking telescopic support system to solve the problems of cumbersome and time-consuming construction procedures in traditional template support structures.
[0006] The objective of this invention is achieved through the following technical solution: The present invention provides a matrix-type self-locking telescopic support system, comprising a support cylinder, a movable top column, an adjusting stud, and a locking adjustment mechanism; Two support cylinders are arranged side by side. Each support cylinder has a base mechanism installed at its bottom and a movable top column that slides through its top. Each movable top column has a screw-on early removal head at its top. A connecting plate is installed between the two movable top columns. The adjusting stud is threaded onto the connecting plate. A connecting block is installed at the bottom end of the adjusting stud. A torque transmission hole is installed at the bottom of the connecting block. The locking adjustment mechanism includes a first limiting component, a second limiting component, and a driving component. The driving component can switch the locking adjustment mechanism to a first position or a second position. In the first position, the first limiting component locks the relative position of the movable top column and the support cylinder, while the second limiting component releases the axial limit on the adjusting stud. In the second position, the first limiting component releases the position lock between the movable top column and the support cylinder, while the second limiting component restricts the axial displacement of the adjusting stud.
[0007] Furthermore, the movable top column is provided with a plurality of adjustment holes axially extending toward the adjustment stud, and the support cylinder is provided with through holes on both sides, the through holes being able to align with the two ends of any adjustment hole. One of the first limiting components is installed on each support cylinder. The first limiting component includes two clamping plates, the two clamping plates being located outside the two through holes respectively, and being slidably installed on the support cylinder in a direction close to or far from each other. The clamping plates are provided with fixing pins that slide through the corresponding through holes. The sidewall of the connecting block is provided with a connecting ring groove. The second limiting component includes two shifting support rods. The two shifting support rods are respectively installed on a clamp plate near the adjusting stud in each first limiting component. The far end of the shifting support rod is provided with a fastening part that can extend into the connecting ring groove. The driving component is used to drive the two clamping plates of each first limiting component to move closer to or further away from each other synchronously.
[0008] Furthermore, one drive assembly is installed on each support cylinder. The drive assembly includes a sliding sleeve, a gear shaft, a first rack, and a second rack. The two gear shafts are rotatably installed on both sides of the support cylinder where the two clamping plates are located. The sliding sleeve is slidably installed on the support cylinder. Two sets of first racks are vertically installed on the sliding sleeve and mesh with the two gear shafts respectively. The two sets of second racks are installed on the two clamping plates and mesh with the gear shafts on the corresponding sides.
[0009] Furthermore, a drive plate is connected between the sliding sleeves of the two drive components, and an opening is provided on the drive plate directly below the torque transmission hole.
[0010] Furthermore, the base mechanism includes two horizontal posts symmetrically arranged at the bottom end of the same support cylinder. One end of each horizontal post is close to the other, and a first rotating shaft is provided on the side of that end that is close to the other support cylinder. The first rotating shaft is rotatably installed at the bottom end of the support cylinder. A control frame is installed at the bottom of the drive plate, and multiple locking rods are installed at the bottom of the control frame. Two horizontal posts at the bottom of the same support cylinder are respectively provided with locking slots on the side near the other support cylinder. The horizontal posts can rotate to approach the control frame and allow the corresponding locking rods to enter the locking slots. A limiting structure is installed at the opening of the locking slots, and the limiting structure can prevent the locking rods from moving laterally out of the locking slots.
[0011] Furthermore, the limiting structure includes a second rotating shaft, a first baffle, and a second baffle. The first baffle and the second baffle are respectively installed on both sides of the second rotating shaft. The second rotating shaft is rotatably installed on one side of the slot opening of the snap-fit groove, and a torsion spring is installed at the rotatable connection to provide elastic force to drive the first baffle to abut against the side wall of the horizontal pile, and to block the second baffle in the slot opening of the snap-fit groove.
[0012] Furthermore, the early disassembly head includes a support rod, a first half-ring, a second half-ring, and a locking assembly; The top end of the support rod is equipped with a top support plate and the bottom end is provided with a threaded section, which is threadedly connected to the movable top column. The first half-ring buckle has support blocks at both ends. A control groove is provided on the top of the support block near the inner side of the first half-ring buckle. Side baffles are slidably installed in the two control grooves in the direction of approaching or away from the first half-ring buckle. The second half-ring is slidably mounted on the first half-ring in a direction that approaches or moves away from the first half-ring. Each end of the second half-ring is provided with a clamping plate, and when the second half-ring approaches the first half-ring, the clamping plate can abut against the side baffle. The first half-ring and the second half-ring are placed on the outside of the support rod, and the locking assembly can clamp the first half-ring and the second half-ring onto the support rod.
[0013] Furthermore, a load-bearing plate is connected between the two support cylinders. A sliding groove is provided on the load-bearing plate above the two transposition struts. A connecting block is slidably installed in the sliding groove. The bottom of the connecting block is connected to the corresponding transposition strut, and a pressure block is installed on the top of the connecting block.
[0014] Furthermore, on one side of the plane where the line connecting the two support cylinders is located, there are two intersecting telescopic columns. The bottom end of the telescopic column is rotatably connected to the bottom side of one of the support cylinders, and the top end is rotatably connected to the top side of the movable top column of the other support cylinder. The telescopic column includes a telescopic sleeve and a telescopic shaft. The telescopic shaft slides through the telescopic sleeve, and a locking stud is threaded onto the side wall of the telescopic sleeve. The locking stud can be inserted into the telescopic sleeve and abut against the telescopic shaft.
[0015] Furthermore, mounting blocks are respectively provided on the bottom sides of the two support cylinders away from each other and on the top sides of the two movable top columns away from each other. Each mounting block is provided with a threaded hole, and a telescopic column is rotatably connected to each mounting block. The distal end of the telescopic column is threaded with a connecting stud that matches the threaded hole.
[0016] As can be seen from the above technical solution, the present invention provides a matrix-type self-locking telescopic support system: 1. Adopting an integrated modular design, it replaces the traditional manual erection method of individual steel pipes and fasteners. It eliminates the need for on-site assembly of numerous components such as uprights and crossbars. A single support unit can be unfolded to form a complete support structure, achieving a seamless switch between rapid adjustment of support height and mechanical rigid locking. It eliminates the need for manual adjustment of uprights one by one, significantly shortening the leveling time. It also specifically solves the problems of easy movement of studs during adjustment and easy damage of studs under load in traditional telescopic supports. In the adjustment state, axial limiting ensures that the adjusting studs only transmit rotational torque, preventing them from moving up and down and ensuring accurate and reliable height adjustment. In the load-bearing state, the load is completely transferred to the movable top column and support cylinder. The adjusting studs no longer bear the vertical pressure of the formwork, concrete, etc., avoiding the risk of long-term deformation, stripping, and breakage of the threaded pair under pressure. 2. When the drive assembly moves the two clamping plates closer together, the fixing pin passes through the through hole and inserts into the adjustment hole, rigidly locking the movable top column and the support cylinder. At the same time, the shifting strut moves with the clamping plate, and the fastening part disengages from the connecting ring groove, completely releasing the axial limit on the adjusting stud, leaving the adjusting stud in a stress-free idle state. When the drive assembly moves the two clamping plates away from each other, the fixing pin exits the adjustment hole, releasing the rigid lock on the movable top column. At the same time, the shifting strut moves towards the adjusting stud, and the fastening part engages with the connecting ring groove. The upper and lower groove walls restrict all axial displacement of the adjusting stud, allowing it to rotate only around the axis. The locking and unlocking of the movable top column and the limiting and disengagement of the adjusting stud are achieved synchronously through a single drive action, eliminating the need for step-by-step operations and greatly improving adjustment efficiency. 3. When switching from the first station to the second station to adjust the system height, push the drive plate upwards, causing the two sliding sleeves to move synchronously upwards along the support cylinder. Through the drive assembly, the two clamping plates move synchronously away from the support cylinder, the fixing pin completely exits the adjustment hole, and the shifting strut precisely engages with the connecting ring groove. The vertical load of the system is transferred from the movable top column to the adjusting stud. The vertical load of the adjusting stud presses down on the shifting strut through the lower groove wall of the connecting ring groove. The shifting strut drives the clamping plate and the second rack to exert a downward force on the gear shaft, creating a gravity self-locking effect on the entire drive assembly. The drive plate can automatically maintain its position in the second station. After switching to the second station, the vertical load borne by the adjusting stud acts in the opposite direction on the drive assembly through the shifting strut, forming a stable self-locking torque. The drive plate automatically maintains its working position. When adjusting the height, there is no need for constant manual upward pulling; one person can complete all adjustment operations with one hand, significantly reducing labor intensity. Subsequent... With the drive plate positioned close to the torque transmission hole, the lithium-ion drill bit can be inserted directly into the torque transmission hole through the through-hole. The drive adjusting stud rotates to adjust the height. After the height adjustment is complete, the drive plate can be pushed down to overcome gravity and self-lock. The drive plate drives the sliding sleeve to move down synchronously, switching the locking adjustment mechanism back to the first position. At this time, the drive plate will return to below the torque transmission hole to form a gap. This gap is greater than the length of the bit but less than the size of the lithium-ion drill. The lithium-ion drill bit will not be able to be inserted into the torque transmission hole, and the lithium-ion drill cannot pass over the drive plate to insert the bit. Therefore, only when the system is switched to the adjustable second position can the through-hole be close to the torque transmission hole, and the lithium-ion drill bit can be inserted smoothly. In the first position, the drive plate is far away from the torque transmission hole. From a physical structure perspective, this eliminates the possibility of workers forcibly adjusting the load under the condition of the movable top column, thus eliminating the need for additional safety locks or limit switches and improving reliability. 4. When the horizontal pile is in the folded state, the locking rod is located in the locking groove of the corresponding horizontal pile, and the limiting structure prevents the locking rod from disengaging from the locking groove, thus limiting the rotation of the horizontal pile. When the drive plate is pushed upward to switch the system to the second position to prepare for height adjustment, the drive plate drives the locking rod to move upward synchronously through the control frame. The locking rod moves upward away from the locking groove to release the limitation on the horizontal pile. Then the horizontal pile can be rotated outward around the first rotating axis to form an anti-overturning support for the bottom of the system. After the support work is completed, the horizontal pile can be rotated inward again and the drive plate can be pushed downward. The locking rod will then engage with the locking groove again to limit the horizontal pile. Attached Figure Description

Detailed Implementation
[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0020] like Figure 1-10 As shown, this embodiment provides a matrix-type self-locking telescopic support system, including a support cylinder 1, a movable top column 2, an adjusting stud 3, and a locking adjustment mechanism 4.
[0021] Two support cylinders 1 are arranged side by side. Each support cylinder 1 has a base mechanism 5 installed at the bottom and a movable top column 2 slidably passing through its top. The inner wall of the support cylinder 1 can be inlaid with a wear-resistant nylon bushing to reduce sliding friction resistance. Each movable top column 2 has a screw-on early removal head 6 at its top.
[0022] A connecting plate 21 is installed between the two movable top posts 2. The adjusting stud 3 is threaded onto the connecting plate 21. A connecting block 31 is installed at the bottom of the adjusting stud 3. A torque transmission hole 311 is installed at the bottom of the connecting block 31. The torque transmission hole 311 is used to connect with tools such as lithium drills to transmit torque to drive the adjusting stud 3 to rotate. The torque transmission hole 311 can be a general standard internal hexagonal hole or other types of holes.
[0023] The locking adjustment mechanism 4 is used to adjust the tightness between the support cylinder 1 and the movable top column 2. The locking adjustment mechanism 4 includes a first limiting component 41, a second limiting component 42, and a driving component 43. The driving component 43 can switch the locking adjustment mechanism 4 to the first position or the second position. In the first position, the first limiting component 41 locks the relative position of the movable top column 2 and the support cylinder 1, while the second limiting component 42 releases the axial limit on the adjusting stud 3. In the second position, the first limiting component 41 releases the position lock between the movable top column 2 and the support cylinder 1, while the second limiting component 42 restricts the axial displacement of the adjusting stud 3.
[0024] When the system is deployed, the locking adjustment mechanism 4 is switched to the second position via the drive component 43. The first limiting component 41 releases the rigid connection between the movable top column 2 and the support cylinder 1, and the second limiting component 42 engages the adjusting stud 3, completely restricting its axial displacement and retaining only the rotational freedom of the adjusting stud 3 around its own axis. The bit of a tool such as a lithium drill is inserted into the torque transmission hole 311, driving the adjusting stud 3 to rotate. This drives the connecting plate 21 and the two movable top columns 2 to rise and fall synchronously along the support cylinder 1 via threaded transmission, adjusting to the target support height. After the height adjustment is completed, the locking adjustment mechanism 4 is switched to the first position via the drive component 43. The first limiting component 41 rigidly locks the movable top column 2 to the support cylinder 1, and the second limiting component 42 releases the lock on the adjusting stud 3. The vertical load of the system is transferred from the movable top column 2 to the support cylinder 1, and the adjusting stud 3 is completely released from the stress state.
[0025] This invention adopts an integrated modular design, replacing the traditional manual erection method of individual steel pipes and fasteners. It eliminates the need for on-site assembly of numerous components such as uprights and crossbars; a single support unit can be unfolded to form a complete support structure. This enables seamless switching between rapid adjustment of support height and mechanical rigid locking, eliminating the need for manual adjustment of uprights one by one, significantly shortening leveling time. It also specifically solves the problems of easy movement of studs during adjustment and easy damage of studs under load in traditional telescopic supports. In the adjustment state, axial limiting ensures that the adjusting stud 3 only transmits rotational torque, preventing it from moving up and down and ensuring accurate and reliable height adjustment. In the load-bearing state, the load is completely transferred to the movable top column 2 and the support cylinder 1, and the adjusting stud 3 no longer bears the vertical pressure of the formwork, concrete, etc., avoiding the risk of long-term deformation, stripping, and breakage of the threaded pair under pressure.
[0026] Specifically, the movable top column 2 has multiple adjusting holes 22 that are laterally through the adjusting stud 3 in the axial direction. The support cylinder 1 has through holes 11 on both sides. The through holes 11 can be aligned with the two ends of any adjusting hole 22. The first limiting component 41 is installed on each support cylinder 1. The first limiting component 41 includes two clamping plates 411. The two clamping plates 411 are located outside the two through holes 11 respectively, and are slidably installed on the support cylinder 1 through a linear guide pair in the direction of approaching or moving away from each other. The clamping plates 411 are provided with fixing pins 412 that slide through the corresponding through holes 11.
[0027] Preferably, one of the fixing pins 412 on one side of the same first limiting component 41 has a connector 4121 at its distal end, and the other fixing pin 412 has a slot 4122 for the connector 4121 to be inserted into its distal end. When the two clamping plates 411 approach each other simultaneously, the connector 4121 of the fixing pin 412 on one side is inserted into the slot 4122 of the fixing pin 412 on the other side, forming an integral through-type pin, which improves the overall rigidity and shear resistance of the fixing pin 412 and prevents the fixing pin 412 from being bent and deformed.
[0028] Furthermore, each clamping plate 411 has multiple fixing pins 412 longitudinally distributed to achieve multi-point locking, increase the force-bearing area, reduce the load on a single fixing pin 412, and improve locking reliability. Even if a single fixing pin 412 fails, the others can still ensure safety.
[0029] The sidewall of the connecting block 31 is provided with a connecting ring groove 312. The second limiting component 42 includes two shifting support rods 421. The two shifting support rods 421 are respectively installed on a clamping plate 411 near the adjusting stud 3 in each first limiting component 41. The far end of the shifting support rod 421 is provided with a fastening part 422 that can extend into the connecting ring groove 312. Preferably, the side of the fastening part 422 near the connecting ring groove 312 is an arc shape that fits the inner wall of the connecting ring groove 312 so as to better fit the connecting ring groove 312.
[0030] Preferably, a load-bearing plate 12 is connected between the two support cylinders 1. A sliding groove 121 is provided on the load-bearing plate 12 above the two shifting struts 421. A connecting block 122 is slidably installed in the sliding groove 121. The bottom of the connecting block 122 is connected to the corresponding shifting strut 421 and a pressure block 123 is installed on the top. The width of the pressure block 123 is greater than the width of the sliding groove 121. When the shifting strut 421 moves with the clamping plate 411, it drives the connecting block 122 to slide synchronously along the sliding groove 121. When the shifting strut 421 is engaged in the connecting ring groove 312, the pressure of the adjusting stud 3 on the shifting strut 421 will be transmitted to the pressure block 123, and then transmitted to the support cylinder 1 by the load-bearing plate 12, so as to avoid excessive bending of the shifting strut 421.
[0031] The drive assembly 43 is used to drive the two clamping plates 411 of each first limiting assembly 41 to move closer or further away from each other synchronously. When the drive assembly 43 drives the two clamping plates 411 to move closer synchronously, the fixing pin 412 passes through the through hole 11 and inserts into the adjusting hole 22, rigidly locking the movable top column 2 and the support cylinder 1. At the same time, the shifting support rod 421 moves with the clamping plate 411, and the fastening part 422 disengages from the connecting ring groove 312, completely releasing the axial limit on the adjusting stud 3, so that the adjusting stud 3 is in an unloaded and idle state. When the drive assembly 43 drives the two clamping plates 411 to move further away synchronously, the fixing pin 412 exits from the adjusting hole 22, releasing the rigid lock of the movable top column 2. At the same time, the shifting support rod 421 moves towards the adjusting stud 3, and the fastening part 422 engages with the connecting ring groove 312, restricting the entire axial displacement of the adjusting stud 3 through the upper and lower groove walls, allowing it to rotate only around the axis. It should be noted that, in order to ensure smooth connection of longitudinal load-bearing, the fastening part 422 should be partially engaged in the connecting ring groove 312 before the fixing pin 412 is completely disengaged from the adjusting hole 22. The locking and unlocking of the movable top column 2 and the limiting and disengagement of the adjusting stud 3 are realized simultaneously through a single drive action, eliminating the need for step-by-step operation and greatly improving adjustment efficiency.
[0032] One drive assembly 43 is installed on each support cylinder 1. The drive assembly 43 includes a sliding sleeve 431, a gear shaft 432, a first rack 433, and a second rack 434. The two gear shafts 432 are rotatably mounted on both sides of the support cylinder 1 where the two clamping plates 411 are located. The sliding sleeve 431 is slidably mounted on the support cylinder 1. Two sets of first racks 433 are vertically mounted on the sliding sleeve 431, respectively meshing with the two gear shafts 432. The two sets of second racks 434 are respectively mounted on the two clamping plates 411 and mesh with the gear shafts 432 on the corresponding sides. The second racks 434 are arranged along the sliding direction of the clamping plates 411. Pushing the sliding sleeve 431 up and down along the support cylinder 1 causes the first racks 433 on the sliding sleeve 431 to drive the gear shafts 432 on both sides to rotate synchronously. The gear shafts 432 then drive the two clamping plates 411 to move synchronously in opposite directions through the second racks 434, which can realize the smooth switching between the first and second working positions. To further improve the smoothness of transmission, each set of first rack 433 and second rack 434 can be provided with two racks, which are symmetrically arranged at both ends of the gear shaft 432.
[0033] When the support height needs to be locked, the control drive component 43 drives the two clamping plates 411 to move towards each other synchronously, so that the fixing pins 412 on both sides are inserted into the adjustment hole 22 of the movable top column 2 through the through hole of the support cylinder 1 synchronously and thus lock the height of the movable top column 2. When the support height needs to be adjusted, the control drive component 43 drives the two clamping plates 411 to move away from each other synchronously, and the fixing pins 412 on both sides exit the adjustment hole 22 synchronously to release the limit. The movable top column 2 can then be freely slid to adjust to the appropriate height and then re-locked and positioned. The structure adopts a double-sided clamping plate 411 driving the fixing pin 412 to move forward and backward synchronously. During the entire process of the fixing pin 412 being inserted and withdrawn, the forces on the left and right sides are completely symmetrical, avoiding the off-center load torque generated by pushing and pulling on one side. This effectively eliminates the problems of the fixing pin 412 being skewed or misaligned, the hole being stuck, and the relative offset between the support cylinder 1 and the movable top column 2. There is no need for manual alignment of the hole and insertion and removal of the pins on both sides one by one. A single person can quickly complete the locking and unlocking operations, which greatly reduces the intensity of manual operation and improves the efficiency of formwork height adjustment.
[0034] Preferably, a stop bar (not shown) can be provided on the side wall of the support cylinder 1. The stop bar is located below the sliding sleeve 431 and is used to support the sliding sleeve 431 to prevent it from falling and causing the first rack 433 to disengage from the gear shaft 432.
[0035] Preferably, two intersecting telescopic columns 13 are provided on one side of the plane where the line connecting the two support cylinders 1 lies. The bottom end of the telescopic column 13 is rotatably connected to the bottom side of one of the support cylinders 1, and the top end is rotatably connected to the top side of the movable top column 2 of the other support cylinder 1. When the system is deployed, the two intersecting telescopic columns 13 automatically extend as the movable top column 2 rises, forming an X-shaped lateral support; when retracted, they automatically shorten as the movable top column descends, automatically forming a laterally stable structure, eliminating the need for manual erection of scissor bracing, and improving the system's resistance to lateral displacement and overall stability.
[0036] Furthermore, mounting blocks 14 are respectively provided on the bottom sides of the two support cylinders 1 away from each other and on the top sides of the two movable top columns 2 away from each other. Each mounting block 14 has a threaded hole 141 and a telescopic column 13 is rotatably connected to each mounting block 14. The distal end of the telescopic column 13 is threadedly connected to a connecting stud 142 that matches the threaded hole 141. When multiple systems are stacked laterally, the telescopic column 13 on the mounting block 14 of the current system can be stretched to the threaded hole 141 of the mounting block 14 of the adjacent system, following the principle of cross-setting of two telescopic columns 13 on the same side. If one end of the telescopic column 13 is connected to the mounting block 14 above the current system, then the other end of the telescopic column 13 needs to be installed on the threaded hole 141 of the mounting block 14 below the adjacent system through the connecting stud 142, and vice versa, so that the various support systems form a laterally stable structure, further improving the overall anti-lateral displacement capability between the systems.
[0037] Specifically, the telescopic column 13 includes a telescopic sleeve 131 and a telescopic shaft 132. The telescopic shaft 132 is slidably inserted into the telescopic sleeve 131, and a locking stud 133 is threaded onto the side wall of the telescopic sleeve 131. The locking stud 133 can be inserted into the telescopic sleeve 131 and abut against the telescopic shaft 132. After the telescopic shaft 132 slides along the telescopic sleeve 131 to the required length, the locking stud 133 is tightened to fix the telescopic shaft 132 and the telescopic sleeve 131 relative to each other, thereby achieving stepless adjustment of the fixed length.
[0038] In one embodiment, a drive plate 435 is connected between the sliding sleeves 431 of the two drive components 43. A through-hole 4351 is provided on the drive plate 435 directly below the torque transmission hole 311. The through-hole 4351 allows the bit of a tool such as a lithium-ion drill to pass through and blocks the body of the lithium-ion drill below. When switching from the first station to the second station to adjust the system height, the drive plate 435 is pushed upward, causing the two sliding sleeves 431 to move synchronously upward along the support cylinder 1. Through the drive assembly 43, the two clamping plates 411 move away from the support cylinder 1 synchronously, the fixing pin 412 completely exits the adjustment hole 22, and the shifting support rod 421 is precisely engaged in the connecting ring groove 312. The vertical load of the system is transferred from the movable top column 2 to the adjusting stud 3. The vertical load of the adjusting stud 3 is pressed down on the shifting support rod 421 through the lower groove wall of the connecting ring groove 312. The shifting support rod 421 drives the clamping plate 411 and the second rack 434 to form a downward force on the gear shaft 432, forming a gravity self-locking on the entire drive assembly 43. The drive plate 435 can automatically maintain the position of the second station. After switching to the second position, the vertical load borne by the adjusting stud 3 is reversed and applied to the drive assembly 43 through the shifting support rod 421, forming a stable self-locking torque. The drive plate 435 automatically maintains its working position. Height adjustment no longer requires manual lifting; a single person can complete all adjustments with one hand, significantly reducing labor intensity. Subsequently, the drive plate 435 is positioned close to the torque transmission hole 311. The drill bit can be inserted directly into the torque transmission hole 311 through the through-hole 4351, driving the adjusting stud 3 to rotate for height adjustment. After height adjustment, the drive plate 435 can be pushed downwards to overcome gravity and self-lock. The drive plate 435 drives the sliding sleeve 431 to move downwards synchronously, switching the locking adjustment mechanism 4 back to the first position. At this time, the drive plate 435 will return to below the torque transmission hole 311, forming a gap greater than the drill bit length but less than the length of the drill bit. Due to the size of the drill bit, the lithium-ion drill bit cannot be inserted into the torque transmission hole 311, and the drill bit cannot pass over the drive plate 435 to insert the bit. Therefore, only when the system is switched to the adjustable second position can the port 4351 be close to the torque transmission hole 311, and the lithium-ion drill bit can be inserted smoothly. In the first position, the drive plate 435 is far away from the torque transmission hole 311. This eliminates the possibility of workers forcibly adjusting the drill bit while the movable top column 2 is under load, thus eliminating the need for additional safety locks or limit switches and improving reliability.
[0039] In one embodiment, the base mechanism 5 is used for bottom anti-overturning support of the matrix self-locking telescopic support system. The base mechanism 5 includes two horizontal posts 51 symmetrically arranged at the bottom of the same support cylinder 1. One end of the two horizontal posts 51 is close to each other, and a first rotating shaft 52 is provided on the side of that end near the other support cylinder 1 (i.e., another base mechanism 5). The first rotating shaft 52 is rotatably mounted on the bottom of the support cylinder 1. The two horizontal posts 51 can rotate outward to form a continuous horizontal column, perpendicular to the vertical plane where the two support cylinders 1 are located, or rotate inward and fold to be within the vertical plane where the two support cylinders 1 are located. The foldable horizontal post design eliminates the need for disassembly. After folding, it is coplanar with the two support cylinders 1, significantly reducing the storage volume. It can achieve multi-layer compact stacking for storage and transportation, improving space utilization. After unfolding, it can increase the support area and significantly improve the anti-overturning stability of the system.
[0040] Preferably, a control frame 4352 is installed at the bottom of the drive plate 435. Multiple locking rods 4353 are installed at the bottom of the control frame 4352. Locking slots 511 are respectively opened on the side of the two horizontal posts 51 at the bottom of the same support cylinder 1 near the other support cylinder 1 (i.e., the other base mechanism 5). The locking slots 511 extend vertically through the horizontal posts 51, allowing the horizontal posts 51 to rotate and approach the control frame 4352, causing the corresponding locking rods 4353 to enter the locking slots 511. A limiting structure 512 is installed at the opening of the locking slots 511, preventing the locking rods 4353 from moving laterally out of the locking slots 511. In the initial state, the horizontal posts 51 are folded, and the locking rods 4353 are located within the locking slots 511 of the corresponding horizontal posts 51. The limiting structure 512 prevents the locking rods 4353 from disengaging from the locking slots 511, thus limiting the rotation of the horizontal posts 51. When the drive plate 435 is pushed upward to switch the system to the second position for height adjustment, the drive plate 435 drives the locking rod 4353 to move upward synchronously through the control frame 4352. The locking rod 4353 moves upward away from the locking groove 511 to release the restriction on the horizontal pile 51. Then the horizontal pile 51 can be rotated outward around the first rotating shaft 52 to form a bottom anti-overturning support for the system. After the support work is completed, the horizontal pile 51 can be rotated inward again to fold it, and the drive plate 435 is pushed downward. The locking rod 4353 is locked into the locking groove 511 again to restrict the horizontal pile 51.
[0041] During routine storage and transportation, the two horizontal posts 51 are rotated inward and folded together, so that the locking rod 4353 is inserted into the locking groove 511. The locking rod 4353 keeps the horizontal posts 51 in a closed and fixed state. When the support height needs to be adjusted on site, the drive plate 435 is pushed upward. The upward movement of the drive plate 435 drives the drive component 43 to move, and the fixing pins 412 on both sides simultaneously disengage from the adjustment hole 22, unlocking the movable top column 2 to achieve height adjustment. At the same time, the upward movement of the drive plate 435 drives the control frame 4352 and the locking rod 4353 to rise simultaneously. The locking rod 4353 disengages from the locking groove 511, releasing the storage lock on the horizontal posts 51. After the horizontal posts 51 are unrestrained, they can naturally rotate outward and unfold to form a stable base. The horizontal posts 51 are unfolded and positioned in advance before the height adjustment, eliminating the risk of tipping over caused by the air conditioner being suspended at the height and the base not being supported on the ground.
[0042] Specifically, the limiting structure 512 includes a second rotating shaft 5121, a first baffle 5122, and a second baffle 5123. The first baffle 5122 and the second baffle 5123 are respectively installed on both sides of the second rotating shaft 5121. The second rotating shaft 5121 is rotatably installed on one side of the slot of the snap-fit groove 511, and a torsion spring (not shown) is installed at the rotatable connection to provide elastic force to drive the first baffle 5122 to abut against the side wall of the cross post 51, and to block the second baffle 5123 in the slot of the snap-fit groove 511. After the support work is completed, when rotating the folding cross post 51 inward, there is no need to repeatedly pull the locking rod 4353. The locking rod 4353 can directly enter the locking groove 511 and push the second baffle 5123 to flip into the locking groove 511. After the locking rod 4353 disengages from the second baffle 5123, the second baffle 5123 will return to the opening of the locking groove 511 under the elastic force of the torsion spring. The first baffle 5122 abuts against the side wall of the cross post 51 under the action of the torsion spring, preventing the second baffle 5123 from continuing to flip outward, thereby preventing the locking rod 4353 from disengaging from the locking groove 511, realizing one-way locking of the locking rod 4353, simplifying the locking operation and improving convenience.
[0043] Preferably, one of the horizontal posts 51 in the same base mechanism 5 is provided with an elastic hook 513 at one end near the adjacent horizontal post 51, and the far end of the elastic hook 513 has a barb 5131. The other horizontal post 51 in the same base mechanism 5 is provided with a hook groove 514 for the elastic hook 513 to pass through at one end near the adjacent horizontal post 51. A side groove 5141 is provided on one side of the hook groove 514 for the barb 5131 to be engaged. When the two horizontal posts 51 are extended outward to form a continuous column, the elastic hook 513 will be inserted into the hook groove 514, and the barb 5131 will automatically engage with the side groove 5141, locking the two horizontal posts 51 together. This achieves automatic locking of the base mechanism 5 under load, further improving the anti-overturning stability. To unlock, the horizontal post 51 can be separated by pressing the barb 5131 in the side groove 5141.
[0044] Preferably, one of the horizontal posts 51 in each base mechanism 5 is rotatably connected to a push plate 519 via a fourth elastic element 518 on the side closest to the control frame 4352. When two horizontal posts 51 of the same base mechanism 5 rotate close to the control frame 4352, they can compress the fourth elastic element 518. The fourth elastic element 518 can be a spring. When the horizontal post 51 is in a folded state, the two adjacent horizontal posts 51 will compress the fourth elastic element 518, accumulating elastic potential energy. When the drive plate 435 is pushed upward to switch the system to the second position to prepare for height adjustment, the locking rod 4353 releases the restriction on the horizontal post 51. Then, under the action of the fourth elastic element 518, the two adjacent horizontal posts 51 spring apart, causing the horizontal posts 51 to automatically unfold outward around the first rotating shaft 52. When the ends of the two horizontal posts 51 collide, they are fixed by inserting the elastic hook strip 513 into the hook groove 514, thereby automatically realizing the anti-overturning support before the height adjustment of the support system.
[0045] Furthermore, one of the horizontal posts 51 in the same base mechanism 5 is provided with an elastic hook strip 513 at the end furthest from the adjacent horizontal post 51. The distal end of the elastic hook strip 513 has a barb 5131. The other horizontal post 51 in the same base mechanism 5 is provided with a hook groove 514 at the end furthest from the adjacent horizontal post 51, into which the elastic hook strip 513 passes. A side groove 5141 is provided on one side of the hook groove 514 for the barb 5131 to be engaged. When multiple support systems are stacked horizontally, adjacent support systems can be quickly spliced directly through the elastic hook strip 513 and hook groove 514 at the distal end of the horizontal post 51, improving the overall stability of the system.
[0046] Specifically, a top pin 515 is slidably installed in each side groove 5141. One end of the top pin 515 extends out of the side groove 5141 and is connected to the side wall of the horizontal post 51 by a first elastic element 5151. The first elastic element 5151 can be a spring. Pressing the top pin 515 pushes the barb 5131 away from the side groove 5141, thereby unlocking the elastic hook 513, making the operation more convenient.
[0047] Preferably, each horizontal post 51 is equipped with a caster wheel 516 at its bottom for easy movement of the system to the load-bearing area. Specifically, each horizontal post 51 has a receiving groove 517 at its bottom, and the caster wheel 516 is located in the corresponding receiving groove 517 and connected to the inner wall of the receiving groove 517 via a second elastic element (not shown). The second elastic element can be a spring; compressing the second elastic element can completely retract the caster wheel 516 into the receiving groove 517. When the system is unloaded, the second elastic element pushes the caster wheel 516 out of the receiving groove 517, allowing the system to move freely. When the system is under load, the vertical load compresses the second elastic element, forcing the caster wheel 516 into the receiving groove 517, and the bottom surface of the horizontal post 51 directly contacts the ground for load bearing. This design balances ease of movement with load-bearing stability; when under load, the caster wheel 516 is not subjected to force, avoiding long-term damage from pressure and extending its service life.
[0048] In another embodiment, a single support cylinder and a movable top column can be matched to form an independent telescopic support structure. The telescopic support structure is equipped with a first limiting component 41 and a driving component 43 for adjusting the tightness. In this embodiment, the first rotating shaft 52 can be installed on either side of the end of the horizontal pile 51, but the two rotating shafts 52 must be on the same side. The control frame 4352 is connected to the sliding sleeve 431 through the driving plate 435 for controlling the retraction and unfolding of the horizontal pile 51.
[0049] In one embodiment, the early removal head 6 includes a support rod 61, a first half-ring 62, a second half-ring 63, and a locking assembly 64.
[0050] The top of the support rod 61 is equipped with a top support plate 611 and the bottom is provided with a threaded section 612, which is threadedly connected to the movable top column 2.
[0051] The first half-ring buckle 62 has support blocks 621 at both ends. The top of the support block 621 is provided with a control groove 6211 on the side near the inside of the first half-ring buckle 62. Side baffles 622 are slidably installed in the two control grooves 6211 in the direction of approaching or away from the first half-ring buckle 62.
[0052] Specifically, the side wall of the control slot 6211 is provided with a slide rail 6212, a sliding block 6213 is slidably installed on the slide rail 6212, and a side baffle 622 is installed on the sliding block 6213.
[0053] The second half-ring 63 is slidably mounted on the first half-ring 62 in a direction that approaches or moves away from the first half-ring 62. Clamping plates 631 are respectively provided at both ends of the second half-ring 63, and when the second half-ring 63 approaches the first half-ring 62, the clamping plates 631 can abut against the side baffle 622. Preferably, an anti-slip pad layer 6311 is provided on the inner side of the clamping plate 631. The anti-slip pad layer 6311 can be made of rubber or have an anti-slip pattern pressed onto its surface to generate sufficient static friction and positive pressure to firmly lock the side baffle 622 in its current position.
[0054] Furthermore, the side baffle 622 is provided with an abutment part 6221 on the side away from the clamping plate 631. The abutment part 6221 slides and fits against the side wall of the control groove 6211. When the side baffle 622 slides in and out with the sliding block 6213, the abutment part 6221 always maintains surface contact with the inner side wall of the control groove 6211. When the side baffle 622 is subjected to lateral pressure from the keel, the abutment part 6221 evenly transfers the load to the side wall of the control groove 6211, preventing the sliding block 6213 and the slide rail 6212 from bearing lateral bending moment.
[0055] The first half-ring 62 and the second half-ring 63 are fitted onto the outside of the support rod 61, and the locking assembly 64 can clamp the first half-ring 62 and the second half-ring 63 onto the support rod 61.
[0056] When installing the keel, put the first half-ring buckle 62 and the second half-ring buckle 63 onto the support rod 61, adjust to the required height and pre-tighten. Place the keel on the top surface of the two side support blocks 621, push the two side baffles 622 to slide towards the keel, so that the inner side of the side baffles 622 fits tightly against the two sides of the keel. Push the second half-ring buckle 63 to slide towards the first half-ring buckle 62, so that the clamping plates 631 at both ends of the second half-ring buckle 63 abut against the outer end faces of the two side baffles 622 respectively, and tighten and fix the side baffles 622 in the current position. Use the locking assembly 64 to clamp and fix the first half-ring buckle 62 and the second half-ring buckle 63 as a whole onto the support rod 61, thus completing the installation and positioning of the keel.
[0057] The freely sliding side baffle 622 can adapt to different widths of timber and steel keel, eliminating the need for pre-customization or replacement of different specifications of early removal heads, greatly improving versatility. The side baffle 622 can be flexibly adjusted according to the actual width of the keel. During installation, the keel is placed first and then the side baffle 622 is adjusted, completely avoiding the problems of traditional fixed side baffles 622 being too close, causing installation jamming, or too far, failing to fit effectively. This ensures that the side baffle 622 fits tightly with the side of the keel, with reliable positioning.
[0058] Specifically, the locking assembly 64 includes a buckle plate 641 and a fixing stud 642. The buckle plate 641 has parallel guide slide plates 6411 at both ends. The distal ends of the two guide slide plates 6411 are fixedly connected to the inner ends of the first half-ring buckle 62. The second half-ring buckle 63 has sliding openings 632 at both ends that are slidably mounted on the guide slide plates 6411. The fixing stud 642 is threaded onto the buckle plate 641, and its end abuts against the second half-ring buckle 63. By tightening the fixing stud 642, the end of the fixing stud 642 pushes the second half-ring buckle 63 to slide smoothly along the guide slide plates 6411 towards the first half-ring buckle 62, causing the clamping plate 631 to gradually press against the side baffle 622. Finally, the first half-ring buckle 62 and the second half-ring buckle 63 are clamped and fixed onto the support rod 61. Loosening the fixing stud 642 allows for vertical adjustment of the half-ring buckle height. The guide plate 6411 ensures that the second half ring buckle 63 moves smoothly in a straight line without deviation, and ensures that the clamping plates 631 on both sides simultaneously press against the side baffles 622, so that the side baffles 622 on both sides are evenly stressed, and avoids the keel tilting due to unilateral stress.
[0059] Preferably, an end block 6214 is installed at the end of the slide rail 6212. The end block 6214 and the slide block 6213 are directly connected by a third elastic element 6215. The third elastic element 6215 can be a spring to provide an elastic force to pull the slide block 6213 toward the first half-ring buckle 62. Before placing the keel, first pull the side baffle 622 to slide away from the first half-ring buckle 62 to overcome the pulling force of the third elastic element 6215, so that the distance between the two side baffles 622 is greater than the width of the keel, leaving enough space for placement. Place the keel stably on the top surface of the two side support blocks 621. After adjusting the keel to the appropriate position, release the side baffle 622. The third elastic element 6215 automatically pulls the slide block 6213 and the side baffle 622 to slide toward the first half-ring buckle 62, so that the inner side of the side baffle 622 automatically approaches the side of the keel, which can complete the automatic pre-positioning of the keel.
[0060] Furthermore, the side baffle 622 is slidably mounted on the sliding block 6213. A limiting shaft 6216 is installed on the side wall of the control groove 6211 away from the first semi-ring 62. The limiting shaft 6216 is located below the sliding block 6213 and is spaced apart from the inner wall of the control groove 6211 away from the first semi-ring 62. It should be noted that when no external force is applied, the static friction between the side baffle 622 and the sliding block 6213 is greater than its own weight, so it will not slide up and down on its own and will always remain in a relatively static state. Before placing the keel, manually pull the side baffle 622 to slide it to its maximum stroke away from the first semi-ring 62. At this point, the bottom of the side baffle 622 is directly above the gap between the limiting shaft 6216 and the inner wall of the control groove 6211. Manually press the side baffle 622 downwards to make it engage with the gap between the limiting shaft 6216 and the inner wall of the control groove 6211. At this point, the limiting shaft 6216 blocks the inner side of the side baffle 622, preventing it from rebounding inwards under the pulling force of the third elastic element 6215, thus temporarily locking the side baffle 622. After the keel is placed, the side baffle 622 can be pushed upwards to automatically fit the keel. Manually pulling open and pressing down locks the side baffle 622, eliminating the need to hold it with your hands and allowing one person to easily complete the keel installation.
[0061] Preferably, a rocker plate 623 is rotatably mounted on the side wall of the control groove 6211 below the sliding block 6213. Both ends of the rocker plate 623 are bent upwards, and one end of the rocker plate 623 is located in the area between the limiting shaft 6216 and the inner wall of the control groove 6211 away from the first half-ring buckle 62. When one end of the rocker plate 623 in the direction of the limiting shaft 6216 is below the limiting shaft, the other end of the rocker plate 623 will protrude from the top of the control groove 6211. When the side baffle 622 is pressed into the gap between the limiting shaft 6216 and the inner wall of the control groove 6211, it will push one end of the rocker plate 623 in the gap area downward. When the keel is placed, the bottom of the keel presses down the end of the rocker plate 623 away from the limiting shaft 6216. The rocker plate 623 rotates around the pin and the end located in the direction of the limiting shaft 6216 tilts upward at the same time, pushing the side baffle 622 upward from the gap, so that it is completely free from the obstruction of the limiting shaft 6216. After the side baffle 622 is unlocked, the third elastic element 6215 pulls it to slide inward to fit the keel. The keel's own weight triggers the unlocking action, and there is no need to manually unlock the side baffle 622.
[0062] Preferably, a load-bearing support rod 613 is radially provided on the support rod 61. The first half-ring buckle 62 and the second half-ring buckle 63 are put on the support rod 61 and slid down until they are completely placed on the load-bearing support rod 613. The load-bearing support rod 613 bears all the vertical load. After tightening the locking assembly 64, the half-ring buckle is clamped and fixed on the support rod 61, forming a dual load-bearing and locking structure.
[0063] Preferably, the inner sides of the first half-ring 62 and the second half-ring 63 have anti-slip textures. When the fixing stud 642 is tightened, the first half-ring 62 and the second half-ring 63 retract inward, and the inner anti-slip textures tightly engage with the surface of the support rod 61 to form a mechanical interlocking structure, generating a friction force much greater than that of a smooth surface.
[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
