[0002] Marine scaffolding refers to temporary support structures installed for ship construction, repair, modification and other operations. They are usually made of steel pipes and steel plates, with casters at the bottom to move them to the required position. Once the position is determined, the scaffolding will be supported on the ground and the user can set up a working platform on it. Fixed scaffolding also needs to be firmly fixed during the installation process to ensure that it will not move or collapse during use.

[0003] In the process of erecting and dismantling existing ship scaffolds, a pulley tool is needed to lift and lower heavy objects. However, the pulley tool for erecting and dismantling existing ship scaffolds still has certain shortcomings in actual use: the existing pulley tool lacks a structure to prevent accidental falling of the heavy objects, which causes accidents caused by the falling of the heavy objects and harms the construction site and personnel. Based on the existing technical deficiencies, the present invention designs a scaffold erection and dismantling tool. Summary of the invention

[0008] As a preferred technical solution of the present invention, an anti-jump structure is fixedly installed on one side of one of the plate racks, and the anti-jump structure includes a side plate, and a fixing plate is fixedly installed on the top of the side plate.

[0009] As a preferred technical solution of the present invention, a threaded rod is rotatably mounted inside the fixed plate, and a turning handle is fixedly mounted on the top of the threaded rod.

[0010] As a preferred technical solution of the present invention, a threaded block is threadedly installed on the outer surface of the threaded rod, and a cross bar is fixedly installed on one side of the threaded block.

[0011] As a preferred technical solution of the present invention, a groove baffle is fixedly installed on one end of the cross bar, and an empty groove is arranged inside the groove baffle.

[0014] As a preferred technical solution of the present invention, the two side blocks are internally threaded with hangers.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The scaffold erection and dismantling tooling has an anti-missing structure. When the device is used, the rope is buckled inside the buckle. After the scaffold erection and dismantling parts are hoisted on the hoisting structure, the construction personnel lift and lower the parts by pulling the other end of the rope. If the construction personnel accidentally let the rope slip, the infrared speed meter arranged inside the inner side of the plate frame detects the passing speed of the rope. When the speed is greater than the set speed, the push cylinder is driven by an electrical signal to make its telescopic rod drive the sliding bar to slide in the slide rail through the connecting plate and the connecting rod, so that the buckle pulls the rope to move to one side of the friction block, so that the rope and the friction block are in contact, and the friction between the two slows down, which makes it easier for the construction personnel below to control the erection and dismantling parts, thereby achieving the purpose of preventing the rope from falling off accidentally, thereby improving the stability and reliability of the tooling, reducing the psychological burden of the operator, and improving the work efficiency and quality;

[0017] 2. The scaffold erection and dismantling tooling has an anti-jumping structure. When the device is in use, the threaded rod can be rotated by turning the handle when the rope is put inside the pulley. Due to the limit of the fixed plate, the threaded block can drive the cross bar to move horizontally on the outer surface of the threaded rod, so that the cross bar can drive the groove baffle to move downward and block the top of the rope, thereby preventing the rope from jumping or sliding out on the pulley during work, thereby avoiding safety accidents caused by this and improving safety;

[0018] 3. The scaffold erection and dismantling tooling, through the hoisting structure, when hoisting the erection and dismantling parts, the suspension rod is rotated out from the inside of the side block, the scaffolding parts are put into the suspension rod, and then the suspension rod is rotated into the side block, thereby preventing the parts from accidentally falling during the hoisting process, thereby improving the safety and working efficiency of the device.

[0030] See also Figure 4-5 Two mounting grooves 68 are provided inside the buckle 63 , a folding plate 69 is hingedly installed inside one mounting groove 68 , and a second fastening bolt 610 is threadedly installed inside the mounting groove 68 on the other side, and the second fastening bolt 610 is threadedly connected to the folding plate 69 .

[0031] When the rope 4 is buckled into the buckle 63 , the second fastening bolt 610 is loosened and removed, and then the rope 4 is buckled into the buckle 63 by folding the folding plate 69 .

[0032] See also Figure 1-2 A clamping groove 5 is provided inside the clamping head 1, and first fastening bolts 51 are threadedly installed on both sides of the clamping groove 5.

[0033] When installing the clamp 1 , the clamping groove 5 is clamped on the edge of the scaffold and fixed by screwing the two first fastening bolts 51 .

[0034] See also Figure 7-8, an anti-jump structure 7 is fixedly installed on one side of one of the plate racks 2, and the anti-jump structure 7 includes a side plate 71, and a fixed plate 72 is fixedly installed on the top of the side plate 71. A threaded rod 73 is rotatably installed inside the fixed plate 72, and a turning handle 74 is fixedly installed on the top of the threaded rod 73. A threaded block 75 is threadedly installed on the outer surface of the threaded rod 73, and a cross bar 76 is fixedly installed on one side of the threaded block 75. A groove baffle 77 is fixedly installed at one end of the cross bar 76, and an empty groove is arranged inside the groove baffle 77.

[0035] The threaded rod 73 can be rotated by turning the handle 74. Due to the limitation of the fixed plate 72, the threaded block 75 can drive the cross bar 76 to move horizontally on the outer surface of the threaded rod 73, thereby the cross bar 76 can drive the groove baffle 77 to move downward and block the top of the rope 4, thereby preventing the rope 4 from jumping or slipping on the pulley 3 during operation.

[0036] See also Figure 2-3 One end of the rope 4 is fixedly mounted with a hoisting structure 8, and the hoisting structure 8 includes a fixing block 81. Side rods 82 are fixedly mounted on both sides of the outer surface of the fixing block 81, and side blocks 83 are fixedly mounted on one side of the two side rods 82. Suspension rods 84 are threadedly mounted inside the two side blocks 83.

[0037] By rotating the suspension rod 84 out from the inside of the side block 83, the parts of the scaffold are sleeved in the suspension rod 84, and then the suspension rod 84 is rotated into the side block 83, thereby preventing the parts from accidentally falling during the lifting process.

[0038] Working principle: when the scaffolding erection and dismantling tool is used, first clamp the clamping groove 5 on the edge of the scaffolding, fix it by screwing the two first fastening bolts 51, then put the rope 4 on the outer surface of the pulley 3, loosen and remove the second fastening bolt 610, and then fold the folding plate 69 to buckle the rope 4 into the buckle ring 63. At this time, turning the handle 74 can make the threaded rod 73 rotate. Due to the limitation of the fixing plate 72, the threaded block 75 can drive the cross bar 76 to move horizontally on the outer surface of the threaded rod 73, so that the cross bar 76 can drive the groove baffle 77 to move downward and block the top of the rope 4, thereby preventing the rope 4 from jumping or sliding out on the pulley 3 during work. During the scaffolding erection and dismantling process, the suspension rod 84 is unscrewed from the inside of the side block 83, and the parts of the scaffold are sleeved in the suspension rod 84. 4 is screwed into the side block 83, thereby preventing the parts from accidentally falling during the hoisting process. After the scaffolding parts are hoisted on the hoisting structure 8, the construction personnel lift and lower the parts by pulling the other end of the rope 4. If the construction personnel accidentally let the rope 4 slip out of their hands, the infrared speed meter arranged inside the plate frame 2 detects the passing speed of the rope 4. When the speed is greater than the set speed, the push cylinder 67 is driven by an electrical signal to make its telescopic rod drive the sliding bar 62 to slide in the sliding rail 61 through the connecting plate 611 and the connecting rod 612, thereby making the buckle 63 pull the rope 4 to move to the side of the friction block 64, thereby making the rope 4 contact with the friction block 64, and decelerating through the friction between the two, thereby making it easier for the construction personnel below to control the erection and dismantling of the parts, thereby preventing the parts from hitting the ground and causing danger.
