Description

Technical Field

[0001] The utility model belongs to the technical field of tower crane safety, and particularly relates to a tower crane safety protection tool. Background Art

[0002] The working principle of a tower crane is to drive a hoisting mechanism through an electric motor or a hydraulic system to lift an object with a pulley on the boom. The length and angle of the boom can be adjusted through a control system to meet different operation requirements. The stability of the tower crane mainly depends on the support of the tower body and the balance of the center of gravity, which is achieved by adjusting the height and inclination angle of the tower body. Tower crane safety is a crucial link in construction. At present, in order to improve the safety of workers climbing the tower crane, a fall arrester is installed on the escalator of the tower crane to enhance the up and down safety of workers. However, due to a large amount of sludge at the construction site and the relatively smooth surface of the escalator, the friction between the worker's sole and the escalator is small after the sole is contaminated with sludge, and it is easy to cause the foot to slip due to wetness. Although there is a fall arrester for safety protection, the worker's body will still hit the tower crane after the foot slips, causing injuries. Therefore, the inventor proposes a tower crane safety protection tool. Summary of the Utility Model

[0023] This detailed implementation manner is a tower crane safety protection tool, and its structural schematic diagram is as shown in Figure 1 shown, including a bottom plate 1, a groove 2, and a tightening mechanism 3. The groove 2 is opened at the bottom of the bottom plate 1, and the groove 2 is an arc-shaped structure. The tightening mechanism 3 is arranged above the bottom plate 1, and the upper surface of the bottom plate 1 has a wearing groove 4. During climbing, the groove 2 at the bottom of the bottom plate 1 contacts the cross bar on the escalator, which can effectively improve the stability. During the climbing process, the safety of the contact between the bottom plate 1 and the escalator is increased, and the phenomenon of slipping in the air during climbing due to wet soles is avoided

[0024] Referring to Figure 2 、 Figure 3 , the tightening mechanism 3 includes a fixed column 10, a binding strap 11, a fixing rod 5, and a lifting block 6. The fixed column 10 is fixedly connected to the upper surface of the bottom plate 1 and is symmetrically distributed in pairs. The two ends of the binding strap 11 respectively penetrate into the inside of the fixed column 10. The inside of the fixed column 10 is a hollow structure, and the binding strap 11 penetrates along the upper surface of the fixed column 10; the fixing rod 5 is fixedly installed on the outer surface of the fixed column 10, and the lifting block 6 is slidably connected to the fixed column 10, and the lifting block 6 penetrates into the inside of the fixed column 10 and is connected to the end of the binding strap 11. The fixing rod 5 is arranged vertically, and a lifting groove 9 is vertically opened on the outer wall of the fixed column 10 corresponding to the fixing rod 5. The lifting block 6 passes through the lifting groove 9, the fixed column 10 is in contact with the lifting block 6, and a plurality of groups of limiting holes 12 are opened on the surface of the fixed column 10 facing the lifting block 6. The plurality of groups of limiting holes 12 are arranged at intervals along the height direction of the fixed column 10

[0025] Referring toFigure 2 , Figure 4 , a plug-in block 14 is protruded on the surface of the lifting block 6 facing the fixed rod 5, and a pull rod 8 is protruded on the surface away from the fixed rod 5. The pull rod 8 is fixedly connected to the plug-in block 14 and both slide through the lifting block 6. A fixing ring 13 is fixed on the outer wall of the end of the pull rod 8 facing the plug-in block 14, and the fixing ring 13 moves synchronously with the plug-in block 14. A spring 15 is fixedly connected to the surface of the fixing ring 13, and the side of the spring 15 away from the fixing ring 13 is fixedly connected to the inner wall of the lifting block 6, and the spring 15 is sleeved on the outside of the plug-in block 14. Sliding holes for the plug-in block 14 and the pull rod 8 to pass through are respectively opened on both sides of the lifting block 6.

[0026] Working principle: When in use, when the operator walks to the bottom of the tower crane escalator, he wears the bottom plate 1 on the sole, and fastens it to the upper through the tightening mechanism 3. The sole is located in the wearing groove 4, and then the pull rod 8 is pulled. The pull rod 8 stretches the spring 15 through the fixing ring 13. The spring 15 is in an expanded state, and the plug-in block 14 moves synchronously with the pull rod 8 and withdraws from the inside of the limit block hole. At this time, the lifting block 6 can be slid down along the lifting groove 9 until the strap 11 is tightly attached to the upper, and then the pull rod 8 is released. The spring 15 is reset, driving the plug-in block 14 to approach the fixing rod 5 again, and then the plug-in block 14 is plugged into the limit holes 12 of other corresponding heights. After multiple lifting blocks 6 are slid down, the strap 1 1 fits tightly on the shoe surface, at this time the bottom plate 1 can be bound to the sole, and then the operator can climb the escalator. When climbing, the groove 2 at the bottom of the bottom plate 1 contacts the crossbar on the escalator, which can effectively improve the stability. During the climbing process, the safety of the contact between the bottom plate 1 and the escalator is increased, avoiding the slipping phenomenon when climbing due to the slippery sole. When the operator climbs to the top of the tower crane, the pull rod 8 can be pulled again. At this time, the lifting block 6 is moved up along the fixed column 10, and the strap 11 can leave the inclined plane, releasing the tightening restriction, and the bottom plate 1 can be taken off from the sole, and it can be put on again when going down the escalator. The operation is convenient, the climbing protection effect for the operators is good, the safety is high, and it can be widely promoted.
