Description

Technical Field

[0001] The invention relates to the technical field of hoisting devices for Bailey frame disassembly construction, in particular to a hoisting device for Bailey frame disassembly construction and a construction method. Background Art

[0002] Bailey frames are lightweight steel truss members widely used in construction projects, bridge construction, and temporary support structures. They are characterized by easy assembly, strong adaptability, and high load-bearing capacity.

[0003] In the prior art, in current construction practice, traditional Bailey frame hoisting devices mostly use a rope binding method, that is, the ropes are directly fixed to the beams or columns of the Bailey frame, and the Bailey frame is lifted and moved to the designated position by hoisting equipment such as a crane.

[0004] However, once hoisted, the Bailey frame, due to its relatively light structure and irregular shape, is subject to various external forces in mid-air, including wind, inertia from the hoisting equipment, and changes in rope tension. The rope binding method cannot effectively secure and restrain the Bailey frame in mid-air, making it prone to swaying. The amplitude and frequency of this swaying are difficult to precisely control, and during the hoisting process, the Bailey frame may collide with surrounding structures, other hoisted objects, or other construction equipment, potentially causing safety accidents, damage to the building structure, damage to other construction equipment, or casualties. Summary of the Invention

[0008] Preferably, the vertical plate is provided with through slots on both sides of the extension slot, and the rear end of the extension plate is connected to connecting plates on both sides. The connecting plates extend from the middle of the through slot, and the connecting plates connect all the extension plates plugged in the middle of multiple groups of vertical plates arranged on one side of the lifting frame.

[0010] Preferably, the tops of the three groups of vertical plates in the middle of the lifting frame are provided with first limiting slots, and the tops of the extension plates connected to the extension slots in the middle of the three groups of vertical plates are also provided with multiple groups of first limiting slots. The bottom of the telescopic plate is provided with multiple groups of first plug-in columns, and the first plug-in columns are perpendicular to the first limiting slots opened on the tops of the vertical plates.

[0011] Preferably, a second telescopic groove is opened at the outer end of the extension plate, a second spring is arranged in the second telescopic groove, the inner side of the second spring is connected to the inner wall of the second telescopic groove, the outer side of the second telescopic groove is connected to the clamping block, and an anti-slip rubber pad is arranged on the inner side of the bottom end of the clamping block.

[0012] Preferably, a third spring is provided in the third telescopic groove opened in the middle of the connecting block provided at the top of the outer end of the extension plate, the inner side of the third spring is connected to the inner wall of the third telescopic groove, the outer side of the third spring is connected to the third spring, and the third spring extends from the opening of the third telescopic groove.

[0013] Preferably, a second limiting slot is opened at one end of the extension plate, and multiple groups of second limiting slots are opened at one end of the clamping block. A second plug-in column is set on the inner side of the telescopic block, and the second plug-in column is parallel to the second limiting slot opened on the side of the extension plate.

[0014] Preferably, a fixed anti-drop plate is provided on one side of the outer end portion of the extension plate, and the bottom of the telescopic anti-drop plate connected to the inner side of the telescopic block is parallel to the fixed anti-drop plate.

[0015] A construction method of a hoisting device for Bailey frame disassembly construction comprises the following steps:

[0016] Step 1: Adjustment. When adjusting the extension length of the extension plate, first press the extension plate upward to disengage the three groups of first plug-in columns set at the bottom of the extension plate from the first limiting slots opened on the top of the extension plate inserted in the middle vertical plate and the middle extension slot of the hanging frame. Then, push the connecting plate to make the connecting plate drive all the extension plates on one side of the hanging frame to slide in the extension slot, and the extension length of the extension plate can be adjusted. When the adjustment is completed, release the pressing of the extension plate. At this time, the first spring in the first telescopic slot opened at the bottom of the top of the support frame pops up the extension plate from the bottom of the first telescopic slot through tension, so that the first plug-in column set at the bottom of the telescopic plate is inserted into the first limiting slot where the vertical plate and the extension plate coincide, thereby fixing the sliding of the extension plate.

[0017] Step 2: Clamping. Place the Bailey frame between the two groups of clamping blocks. At this time, the two groups of clamping blocks are contracted by the contraction force of the second spring in the second telescopic groove, and the Bailey frame is pre-fixed between the two groups of clamping blocks. The anti-slip rubber pad on the inner side of the end of the clamping block can effectively prevent the Bailey frame from slipping from between the two groups of clamping blocks. Then, by loosening and pulling the telescopic block, the third spring in the connecting block resets the telescopic block through the contraction force. At this time, the second plug-in column set on the inner side of the telescopic block is inserted into the second limit slot where the extension plate coincides with one side of the clamping block to fix the clamping of the clamping block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a hoisting device and construction method for Bailey frame disassembly construction. When the disassembled Bailey frame is hoisted, the extension length of the extension plate is first adjusted according to the length of the Bailey frame, so that the distance between the inner sides of the outer ends of the clamping blocks connected to the outer ends of the two groups of extension plates is less than 20 cm of the length of the Bailey frame. When the extension length of the extension plate is adjusted, the telescopic plate is first pressed upward to drive the three groups of first plug-in columns set at the bottom to disengage from the first limiting slots opened on the top of the extension plate inserted in the middle vertical plate and the middle extension slot of the hoisting frame. Then, by pushing the connecting plate, the connecting plate drives all the extension plates on one side of the hoisting frame to slide in the extension slot, and the extension length of the extension plate can be adjusted. When the adjustment is completed, the telescopic plate is released. At this time, the first spring in the first telescopic slot opened at the bottom of the top of the support frame pops out the telescopic plate from the bottom of the first telescopic slot through tension, so that the first plug-in column set at the bottom of the telescopic plate is inserted into the first limiting slot where the vertical plate and the extension plate overlap, thereby fixing the sliding of the extension plate; then, the telescopic block is pulled outward When the second spring is released, the second spring in the second expansion slot is released, and the second expansion slot is released to the left of the extension plate, and the extension plate is released to the right of the extension plate, and the extension plate is released to the right of the expansion slot. The telescopic block is reset. At this time, the second plug-in column set on the inner side of the telescopic block is inserted into the second limit slot which coincides with the extension plate and one side of the clamping block to fix the clamping of the clamping block. Furthermore, a fixed anti-drop plate is provided on one side of the end of the clamping block, and the inner side of the telescopic block is connected to the telescopic anti-drop plate. When the telescopic block is retracted and reset, the telescopic anti-drop plate is inserted under the top frame of the Bailey frame to further prevent the Bailey frame from falling. After multiple groups of Bailey frames are fixed, the crane is connected to the three groups of lifting rings on the top of the lifting frame through ropes, and starts to move the Bailey frame.
