Description

Technical Field

[0001] This utility model relates to the technical field of fall protection safety devices, specifically a fall protection safety device for a large-tonnage monopile vertical pull-out test. Background Technology

[0002] The vertical pull-out bearing capacity test of a single pile refers to the process of testing and analyzing the ability of a single pile to resist vertical pull-out through certain methods. Methods for obtaining the vertical pull-out bearing capacity of a single pile include static load test, empirical formulas in specifications, and theoretical analysis. Through statistical analysis and processing of relevant data, the ultimate pull-out bearing capacity of the test pile in the project can be estimated. The vertical pull-out testing of large-tonnage single piles is an important part of pile foundation engineering. High-altitude operations are required when installing and dismantling equipment before and after testing. These areas may have the risk of falling, and the workers face significant safety risks. Therefore, fall protection safety devices are required.

[0003] Existing fall protection safety devices are not convenient for adjusting the safety rope during use, which affects the efficiency of workers working above. Furthermore, the safety rope is not easy to limit during the release and retraction process, which makes it prone to wear and even jamming.

[0004] Based on this, a fall protection safety device for vertical pull-out tests of large-tonnage monopile is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this utility model is to provide a safety device for preventing falls during vertical pull-out tests of large-tonnage monopile, in order to solve the problem in the prior art where it is inconvenient to adjust the safety rope, which affects the efficiency of workers working above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A safety device for preventing falls during vertical pull-out tests of large-tonnage monopile includes two supports, each with two columns fixedly installed on its top. A lifeline is provided between each pair of columns, and a slider is provided outside the lifeline. A protective shell is fixedly connected to the bottom of the slider.

[0008] A winding mechanism is provided on one outer side of the protective shell, a locking mechanism is provided on the other outer side of the protective shell, and a connecting mechanism is provided on one inner side of the protective shell.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0010] In one alternative: the winding mechanism includes a motor, which is fixedly mounted on one side of the protective housing. The output end of the motor passes through the protective housing and is keyed to a first synchronous pulley. The first synchronous pulley is located inside the protective housing, and one end of the first synchronous pulley is keyed to a winding roller.

[0011] In one alternative: the locking mechanism includes an electric cylinder, which is fixedly installed on the other side of the protective shell. The output end of the electric cylinder passes through the protective shell and is fixedly connected to a first gear.

[0012] In one alternative: the connecting mechanism includes a second synchronous pulley, which is rotatably mounted inside the protective housing, and a synchronous belt is installed between the second synchronous pulley and the first synchronous pulley.

[0013] In one alternative: a reciprocating mechanism is provided on one side of the second synchronous pulley.

[0014] In one alternative embodiment: the reciprocating mechanism includes a reciprocating lead screw, which is keyed to one side of the second synchronous pulley, and one end of the reciprocating lead screw is rotatably mounted to the protective shell.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, a safety device for preventing falls during vertical pull-out tests of large-tonnage monopile includes two supports 1, two columns 2 are fixedly installed on the top of each of the two supports 1, a lifeline 3 is provided between each pair of columns 2, a slider 4 is provided on the outside of the lifeline 3, and a protective shell 5 is fixedly connected to the bottom of the slider 4.

[0027] A winding mechanism 6 is provided on one outer side of the protective shell 5, a locking mechanism 8 is provided on the other outer side of the protective shell 5, and a connecting mechanism 9 is provided on one inner side of the protective shell 5.

[0028] In this embodiment, the worker connects the hook 11 to the safety suit he is wearing. Due to the setting of the slider 4, the protective shell 5 can slide outside the lifeline 3, which is convenient to adjust according to the needs of the worker. When the worker falls, the safety rope 10, the hook 11 and the safety suit will prevent the worker from falling, thus providing a fall protection function and greatly improving the safety of the worker working above.

[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the winding mechanism 6 includes a motor 61, which is fixedly installed on one side of the protective shell 5. The output end of the motor 61 passes through the protective shell 5 and is keyed to a first synchronous pulley 62. The first synchronous pulley 62 is located inside the protective shell 5, and one end of the first synchronous pulley 62 is keyed to a winding roller 63. The rotation of the motor 61 drives the first synchronous pulley 62 to rotate, which in turn drives the winding roller 63 to rotate, causing the safety rope 10 to be released. Since the hook 11 has a certain weight, it moves downward, making it convenient for workers of different heights to pick up the hook 11 and connect it to their safety clothing. When it is necessary to shorten the length of the safety rope 10, the motor 61 rotates in the opposite direction, causing the winding roller 63 to wind up the safety rope 10, which can be adjusted according to needs.

[0030] In one embodiment, such as Figure 2 and Figure 4 As shown, the locking mechanism 8 includes an electric cylinder 81, which is fixedly installed on the other side of the protective shell 5. The output end of the electric cylinder 81 passes through the protective shell 5 and is fixedly connected to a first gear 82. A second gear 83 is fixedly installed on one side of the take-up roller 63, and the second gear 83 is adapted to the first gear 82. When the take-up roller 63 needs to rotate, the electric cylinder 81 retracts to drive the first gear 82 to move, thereby disengaging the first gear 82 from the second gear 83. At this time, the take-up roller 63 can rotate. When the take-up roller 63 needs to be fixed, the electric cylinder 81 extends, causing the first gear 82 to mesh with the second gear 83. At this time, the take-up roller 63 cannot rotate, thus achieving a locking effect.

[0031] In one embodiment, such as Figure 2 and Figure 3 As shown, the connecting mechanism 9 includes a second synchronous pulley 91, which is rotatably mounted inside the protective shell 5. A synchronous belt 92 is installed between the second synchronous pulley 91 and the first synchronous pulley 62. During the rotation of the first synchronous pulley 62, the second synchronous pulley 91 rotates through the cooperation of the synchronous belt 92, thus achieving a linkage effect.

[0032] In one embodiment, such as Figure 3 and Figure 4As shown, a reciprocating mechanism 7 is provided on one side of the second synchronous pulley 91. The reciprocating mechanism 7 allows the safety rope 10 to be evenly wound around the outside of the winding roller 63, thereby improving the quality of the winding of the safety rope 10.

[0033] In one embodiment, such as Figure 3 and Figure 4 As shown, the reciprocating mechanism 7 includes a reciprocating lead screw 71, which is keyed to one side of the second synchronous pulley 91. One end of the reciprocating lead screw 71 is rotatably mounted to the protective shell 5. A matching movable plate 72 is mounted on the outside of the reciprocating lead screw 71. A limiting rod 73 is fixedly mounted inside the protective shell 5 and above the reciprocating lead screw 71. The movable plate 72 and the limiting rod 73 are slidably mounted. A limiting ring 74 is fixedly connected to one side of the movable plate 72. The rotation of the second synchronous pulley 91 drives the reciprocating lead screw 71 to rotate. The rotation of the reciprocating lead screw 71 causes the movable plate 72 to reciprocate along the length direction of the limiting rod 73. Since the limiting ring 74 limits the safety rope 10, the safety rope 10 is evenly wound around the outside of the winding roller 63, improving the winding quality.

[0034] In one embodiment, such as Figure 2 and Figure 4 As shown, a safety rope 10 is sleeved on the outside of the winding roller 63. One end of the safety rope 10 passes through the limiting ring 74 and is connected to a hook 11. A wire 12 is fixedly connected to the bottom of the protective shell 5. The bottom end of the wire 12 is electrically connected to a controller 13. The controller 13 can control the operation of the electric cylinder 81 and the motor 61, which can be adjusted according to the actual use.

[0035] In one embodiment, such as Figure 1 As shown, two mounting beams 14 are provided between the tops of the two supports 1, and a protective steel plate 15 is provided between the tops of the two mounting beams 14. A second mounting beam 16 is provided on the top of the protective steel plate 15. If a worker accidentally steps into the air while working above (16), he will fall back to above (15), which reduces the height from which the worker falls from above (16) and thus reduces the risk of injury.

[0036] The above embodiment discloses a fall protection safety device for a large-tonnage monopile vertical pull-out test. In this device, the motor 61 rotates, which drives the first synchronous pulley 62 to rotate. The rotation of the first synchronous pulley 62 drives the winding roller 63 to rotate, which releases the safety rope 10. Since the hook 11 has a certain weight, it moves downward, making it convenient for workers of different heights to pick up the hook 11 and connect it to their safety clothing. Due to the setting of the slider 4, the protective shell 5 can slide outside the lifeline 3, which is convenient to adjust according to the needs of the workers.

[0037] After the length of the safety rope 10 is adjusted, the electric cylinder 81 extends, causing the first gear 82 to mesh with the second gear 83. At this time, the take-up roller 63 cannot rotate, thus locking the rope. If a worker falls, the safety rope 10, hook 11, and safety clothing will prevent the worker from falling, providing a fall protection function and greatly improving the safety of workers working above. When it is necessary to rewind the safety rope 10, the electric cylinder 81 retracts, causing the first gear 82 to move and disengage from the second gear 83. At this time, the motor 61 drives the take-up roller 63 to rotate, and the second synchronous wheel 91 rotates, driving the reciprocating screw 71 to rotate. The rotation of the reciprocating screw 71 causes the moving plate 72 to move back and forth along the length direction of the limit rod 73. Since the limit ring 74 limits the safety rope 10, the safety rope 10 is evenly wound around the outside of the take-up roller 63.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
