Abstract
Description
Technical Field
[0001] This invention relates to the field of tower crane operating platform technology, and in particular to a support structure, operating platform, and rapid lifting method for a tower crane operating platform. Background Technology
[0002] With the rapid development of cities, more and more high-rise landmark buildings are appearing around us, and the construction of high-rise buildings is closely related to tower cranes.
[0003] Existing tower crane operating platforms are mostly of the coupler-type steel pipe type, relying on couplers to connect the steel pipes. The quality of the connection is greatly affected by the operator's skill level, resulting in low safety and reliability. Moreover, platforms erected using steel pipes can only be set up at the standard section connection layer and horizontal web member layer, which is not flexible enough. Furthermore, the dismantling of coupler-type steel pipe platforms during tower crane dismantling and anchoring significantly delays the dismantling progress. Therefore, designing a safe, reliable, practical, and convenient operating platform is urgently needed.
[0004] The applicant filed a utility model patent application on May 5, 2017, entitled "A Prefabricated Tower Crane Operating Platform Device," with publication number CN206783150U. This prefabricated tower crane operating platform device uses two U-shaped buckles to fix itself to a standard tower crane section, and is bolted together via elongated holes on the U-shaped steel plates of the buckles and elongated holes on the rectangular tubes inside the rectangular plate. This operating platform device only considers the differences in the outer dimensions of the standard tower crane sections, but does not take into account the fact that the size of the standard section columns connecting the two U-shaped buckles may vary depending on the tower crane manufacturer. Therefore, the above-mentioned operating platform device needs further improvement in terms of its compatibility with various models of standard tower crane sections. Furthermore, the operating platform is only supported and fixed to the U-shaped steel plate via the rectangular tubes inside the rectangular plate, resulting in a small supporting area and requiring improvement in the overall stability of the operating platform. Summary of the Invention
[0005] To address the aforementioned problems, the present invention aims to provide a support structure, operating platform, and rapid lifting method for a tower crane operating platform. This operating platform has a simple and stable structure, is easy to operate, and can be quickly and conveniently installed, disassembled, and lifted, greatly improving construction efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A quick-assembly, quick-disassembly, and quick-lifting tower crane operating platform support structure includes a top support, clamps, square beams, and platform locks. The top support includes two blocks located on opposite sides of the inner and outer surfaces of a standard column section. Each block has a horizontally penetrating groove at its upper part for engaging the clamp, and an outwardly extending hook at its lower part for engaging the square beam. The hooks of the two blocks extend perpendicularly to each other. One block has a limiting block positioned higher than the hook. The two blocks are locked to the standard column section by clamps with adjustable tightness. Two mutually perpendicular square beams are provided corresponding to each standard column section. The two square beams are respectively engaged in the hooks of one block, and their ends are engaged below the limiting blocks. Two platform locks are provided corresponding to each square beam. The two platform locks are sleeved on the square beams and lock onto both sides of the platform plate of the operating platform.
[0008] The slot is located on the side opposite to the contact surface of the support block and the standard section column. The hook of one support block and the slot of the support block are located on the same side and the extension directions of the hook and the slot of the support block are perpendicular to each other. The hook of the other support block is located on the adjacent side of the slot of the other support block and the extension directions of the hook and the slot of the support block are parallel to each other. The limiting block of the support block with the limiting block is located on the same side as the hook of the other support block.
[0009] The bottom surface of the limiting block is provided with two grooves, and the side surface of the limiting block is provided with threaded holes that communicate with the grooves. The end of the square beam is provided with a protrusion, which is engaged in the groove and tightened by a tightening bolt passing through the threaded hole.
[0010] The four L-shaped clamps of the clamp respectively hold the four corners of the two support blocks attached to the standard section column and are respectively embedded in the slots of the two support blocks. The two adjacent clamps are connected by a screw rod and the distance between the two clamps is adjusted by the screw rod.
[0011] Among them, the screws on two opposite sides of the clamp are short screws, and the two ends of the short screws are threaded to the two adjacent clamping blocks through end nuts; the screws on the other two opposite sides of the clamp are long screws, and the two ends of the long screws are threaded to the two adjacent clamping blocks and the ends extend outside the clamping blocks and are threaded to a locking nut. The long screws are set on the two slot sides of the two support blocks, and the short screws are set on the two adjacent sides of the slots.
[0012] The platform lock has a square tube sleeved on the outside of the square beam, and an L-shaped hook facing outward is welded on the top of the square tube. One platform lock is sleeved on the inside of the square beam near the standard section column with the hook facing outward, and the other platform lock is sleeved on the outside of the square beam with the hook facing inward. The two hooks are locked onto both sides of the platform plate.
[0013] The square tube has threaded through holes on all sides except the bottom, and screws are screwed into the threaded through holes to press the square beam.
[0014] A quick-assembly, quick-disassembly, and quick-lifting tower crane operating platform includes a platform body and four aforementioned support structures fixed to four standard section columns of the tower crane. The hooks of one support block and the limiting blocks of the other support block on each standard section column are located inside the standard section column. Two square beams corresponding to each standard section column have one end located inside the standard section column and the other end located outside the standard section column. Each platform panel of the platform body forms a U-shape and is supported on the square beams and locked to them by platform locks. A railing is provided for each platform panel.
[0015] Each platform panel has connecting holes on its side. Adjacent platform panels are connected as one unit by U-bolts. Multiple square sleeves with through holes are fixed on the outside of the platform panels. The railing posts are inserted into the square sleeves and connected by cotter pins. Adjacent railings are connected by bolts.
[0016] A rapid lifting method for a quick-assembly, quick-disassembly, and quick-lifting tower crane operating platform, applicable when the platform's ascent is restricted by the tower crane's wall-mounted tie rods during the lifting process, includes the following steps:
[0017] Loosen the platform lock on the fixed tie rod side platform plate, separate the platform plate from the adjacent platform plate, and hoist the separated platform plate to the other side platform plate away from the building;
[0018] Release the remaining platform locks and hoist the U-shaped platform body to the preset height;
[0019] After disassembling the square beam, clamps, and top support, place it on the platform.
[0020] The main body of the platform is lifted from the standard section of the tower crane to the side away from the building, so that the main body of the platform is removed from the standard section. Then the tower crane lifts the main body of the platform to the required height.
[0021] Then, the platform is hoisted to the side of the building to restore its main body, and top supports, clamps, and square beams are installed on the standard column sections.
[0022] The present invention has the following beneficial effects:
[0023] The present invention uses two support blocks, adjustable clamps, and square beams detachably connected to the two support blocks to assemble a support structure for an operating platform that can be quickly installed and disassembled. The platform plate of the operating platform is locked and adjusted by two platform locks on the square beams.
[0024] The system utilizes two support blocks attached to the standard column section and secured with adjustable clamps. The adjustable clamps allow the support structure to accommodate various models of standard column sections. Furthermore, the entire platform is supported by square beams, enhancing the stability of the support structure. Additionally, the platform locks on the square beams can be adjusted according to the external dimensions of the tower crane standard section, further improving the compatibility between the support structure and the tower crane standard section.
[0025] In addition, the rapid lifting method of this operating platform can not only be installed and disassembled quickly, but also achieve rapid disassembly, lifting and installation, especially when the tower crane's wall tie rod restricts the platform's ascent, which greatly improves construction efficiency.

Detailed Implementation
[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0040] Example 1
[0041] See Figures 1 to 11 A support structure 1 for a quick-installation, quick-disassembly, and quick-lifting tower crane operating platform. The support structure 1 is detachably installed on a standard section column 10 and is used to support the platform body 2 of the tower crane operating platform. The support structure 1 includes a top support 11, a clamp 12, a square beam 13, and a platform lock 14.
[0042] The top support 11 includes a first support block 111 and a second support block 112 located on opposite sides of the standard section column 10, with the first support block 111 and the second support block 112 fitted to the side of the standard section column 10. The upper part of the side of the first support block 111 and the second support block 112 opposite to the contact surface of the standard section column 10 has a concave, horizontally penetrating groove 113 for engaging the clamp 12, and the lower part has an outwardly extending hook 114 for engaging the square beam 13. The extension directions of the hooks 114 of the first support block 111 and the second support block 112 are perpendicular to each other. The hooks 114 of the first support block 111 and the grooves 113 of the first support block 111 are located on the same side and the extension directions of the hooks 114 and the grooves 113 of the first support block 111 are perpendicular to each other. The hooks 114 of the second support block 112 are located on the adjacent side of the grooves 113 of the second support block 112 and the extension directions of the hooks 114 and the grooves 113 of the second support block 112 are parallel to each other. The first support block 111 has an L-shaped limiting block 115 on the side adjacent to the first support block 111 hook 114, which is higher than the hook 114. The limiting block 115 of the first support block 111 and the hook 114 of the second support block 112 are located on the same side. Preferably, the bottom surface of the limiting block 115 of the first support block 111 is provided with two concave grooves 116, and the limiting block 115 has threaded holes 117 on the sides of the two grooves 116, which are through the grooves 116 for screwing on the tightening bolts of the tightening beam 13.
[0043] The first support block 111 and the second support block 112, which are attached to both sides of the standard section column 10, are locked to the standard section column 10 by clamps 12. The four L-shaped clamping blocks 121 of the clamps 12 respectively hold the four corners of the first support block 111 and the second support block 112 attached to the standard section column 10 and are respectively embedded in the slots 113 of the first support block 111 and the second support block 112. Adjacent clamping blocks 121 are connected by a threaded rod, and the distance between two clamping blocks 121 is adjusted by the threaded rod. Specifically, the four L-shaped clamping blocks 121 have horizontally penetrating threaded holes 122 along both the transverse and longitudinal directions for easy lubrication and maintenance. The clamp 12 has two short lead screws 123 on opposite sides, with both ends of the short lead screw 123 threadedly connected to two adjacent clamping blocks 121 via end nuts 124. A central nut 125 with a hole is fixed in the middle of the short lead screw 123. The other two opposite lead screws 126 are long lead screws 126, with both ends of the long lead screw 126 threadedly connected to two adjacent clamping blocks 121 and the end extending outside the clamping block 121, threadedly connected to a locking nut 127 via a flat washer and a spring washer. Preferably, the end of the long lead screw 126 is provided with an external hexagonal section 128, which facilitates locking the locking nut 127 when the lead screw rotates, and can be quickly loosened by rotating the external hexagonal section 128 with an open-end wrench. The long lead screw 126 is located on the two slots 113 sides of the first support block 111 and the second support block 112, and the short lead screw 123 is located on two adjacent sides of the slots 113.
[0044] Two horizontal square beams 13 are provided corresponding to a standard section column 10. The ends of the square beams 13 are provided with upward-protruding protrusions 131. One end of one square beam 13 is engaged in the hook 114 of the first support block 111 and abuts against the lower limit block 115. The protrusion 131 at the end is engaged in a groove 116 on the bottom surface of the limit block 115. The protrusion 131 of the square beam 13 is locked by a tightening bolt of the limit block 115 passing through a threaded hole 117 on one side. The other square beam 13 is set perpendicular to the first square beam 13. One end is engaged in the hook 114 of the second support block 112 and abuts against the lower limit block 115 of the first support block 111. The protrusion 131 at the end is engaged in another groove 116 on the bottom surface of the limit block 115. The protrusion 131 of the square beam 13 is locked by another tightening bolt of the limit block 115 passing through a threaded hole 117 on the other side.
[0045] Two platform locks 14 are provided for each square beam 13. Each platform lock 14 has a square tube 141 sleeved on the outside of the square beam 13. The square tube 141 has threaded through holes 142 on all sides except the bottom. An L-shaped hook 143 facing outward is welded to the top of the square tube 141. The square tube 141 and the hook 143 are reinforced and connected by triangular ribs 144. One platform lock 14 is sleeved on the inner side of the square beam 13 near the standard section column 10 with the hook 143 facing outward, and the other platform lock 14 is sleeved on the outer side of the square beam 13 with the hook 143 facing inward. The platform body 2 of the tower crane's operating platform is supported on the square beam 13, and the two hooks 143 of the two platform locks 14 are engaged with the two sides of the platform plate 21. The square beam 13 is then pressed by screws screwed into the threaded through holes 142.
[0046] Example 2
[0047] See Figure 1 and Figure 11 A quick-assembly, quick-disassembly, and quick-lifting tower crane operating platform includes a platform body 2 and four support structures 1, as described in Embodiment 1, that support the platform body 2 and are fixed to four standard section columns 10 of the tower crane standard section.
[0048] Four support structures 1 are provided corresponding to the four standard section columns 10 of the tower crane standard section. The limiting block 115 of the first support block 111 and the hook 114 of the second support block 112 on each standard section column 10 are both located inside the standard section column 10. Two square beams 13 corresponding to each standard section column 10 are perpendicular to each other, with one end of each beam 13 located inside the standard section column 10 and engaged in the two grooves 116 of the limiting block 115 of the first support block 111, and the other end located outside the standard section column 10. It should be noted that since each platform plate 21 requires two square beam tubes 13 for support, and the two square beams 13 on each standard section column 10 must form a right angle with their outer ends extending to the outside of the tower crane standard section, four types of support blocks are required for the four standard section columns 10. See [link / reference] Figure 3 and Figure 7 The two support blocks on the two standard column 10s on one diagonal of the tower crane standard section are mirror images of the two support blocks on the two standard column 10s on the other diagonal. Figure 7 The support blocks 111 and 112 are a group, set on the two standard section columns 10 on one of their diagonals. Figure 7 The support blocks 111' and 112' are another set, set on the two standard section columns 10 on the other diagonal, wherein the first support block 111 and support block 111' are mirror images of each other, and the second support block 112 and support block 112' are mirror images of each other.
[0049] The platform body 2 comprises four platform panels 21, two long and two short. The two shorter platform panels 21 are positioned between the two longer platform panels 21, forming a U-shape. Each platform panel 21 has connecting holes on its side. Each platform panel 21 is supported on a square beam 13 and secured by two platform locks 14 on the square beam 13. Adjacent platform panels 21 are connected as a single unit by U-bolts. Multiple square sleeves 22 with through holes are fixed to the outside of each platform panel 21. A railing 23 is provided for each platform panel 21. The uprights of the railing 23 are inserted into the square sleeves 22 and connected by cotter pins. Adjacent railings 23 are connected by bolts.
[0050] Preferably, one of the longer platform plates 21 of the platform body 2 is located on one side of the tower crane's wall tie rod, which facilitates the removal of the platform body 2 from the tower crane's standard section when the platform body 2 is dismantled.
[0051] The installation method for the aforementioned quick-installation, quick-disassembly, and quick-lifting tower crane operating platform includes the following steps:
[0052] Assemble clamp 12: A short lead screw 123 connects two clamp blocks 121 to form two clamp units of clamp 12.
[0053] Locking the top support 11: The first support block 111 and the second support block 112 are placed at the designated positions on the standard section column 10. The two clamp units are locked in the slots 113 of the first support block 111 and the second support block 112, and the two clamp units are connected by a long screw rod 126. Tighten the locking nut 127 on the long screw rod 126 and the end nut 124 on the short screw rod 123 to lock the first support block 111 and the second support block 112 onto the standard section column 10. Lock a corresponding top support 11 on each of the four standard section columns 10 in the same way. Note the orientation of the top support 11 on the four standard section columns 10. The limiting block 115 of the first support block 111 and the hook 114 of the second support block 112 are both located on the inside of the standard section column 10.
[0054] Fixed square beam 13: For each standard section column 10, one of the two square beams 13 has one end inserted into the hook 114 of the first support block 111 and the protrusion 131 at the end inserted into a groove 116 of the limiting block 115, and is locked with a tightening bolt; the other square beam 13 has one end inserted into the hook 114 of the second support block 112 and the protrusion 131 at the end inserted into another groove 116 of the limiting block 115, and is locked with another tightening bolt;
[0055] Install two square beams 13 for each standard column 10 according to the above method.
[0056] Inserting platform locks 14: Insert one platform lock 14 into the inner and outer sides of each beam 13, and set the hooks 143 of the two platform locks 14 on each beam 13 opposite to each other.
[0057] Assemble platform body 2: Fit the railing 23 into the square sleeve 22 of the platform plate 21 and fix it with cotter pins. Connect a long platform plate 21 and a short platform plate 21 with U-bolts to form two L-shaped platform units.
[0058] Fixed Platform Body 2: Hoist the two L-shaped platform units onto the square beams 13, adjust the platform locks 14 on the square beams 13 and use the platform locks 14 to lock the two L-shaped platform units onto the square beams 13. The two L-shaped platform units are connected and fixed with U-bolts.
[0059] Alternatively, the platform body 2 can be assembled first, and then the platform lock 14 can be installed. Each platform plate 21 of the platform body 2 can be installed on the square beam 13 one by one, without having to connect the platform plates 21 into an L-shape before installing them on the square beam 13.
