Description

Technical Field

[0001] The invention relates to the technical field of aerial work, and in particular to an anti-slip fence safety belt. Background Art

[0002] Safety belts are protective equipment for workers to prevent falls and casualties when working at heights. During the pole climbing process, workers use pole climbing foot buckles and pole safety belts to climb. When reaching the working height, workers only need to lean back and maintain a certain angle with the pole to allow the safety belt tied around the waist to bear the force, and at the same time cooperate with the foot buckles to achieve a fixed anti-fall effect.

[0003] However, when workers are working at heights, their limbs often move. When the working posture causes the waist to relax, the pole-holding side of the guardrail safety belt is not sufficiently stressed and the safety belt will slide down. The workers need to pull the safety belt up again to tighten it. The whole process involves frequent sliding down and straightening, which affects the workers' concentration and work efficiency. Any negligence may lead to personal safety accidents. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 5As shown, an embodiment of the present invention provides an anti-slip fence safety belt, which includes a wearing fixing belt 10, an adjustment mechanism 20, a pole fixing belt 30, a pressure detection component 40 and a control component. The wearing fixing belt 10 has a connecting portion 11, and the adjustment mechanism 20 is fixedly arranged on the wearing fixing belt 10. The adjustment mechanism 20 includes a rotating drum 21 and a driving component 22 for driving the rotating drum 21 to rotate. The first end of the pole fixing belt 30 is wound around the rotating drum 21. When the rotating drum 21 rotates, the extension length of the pole fixing belt 30 can be adjusted. The second end of the pole fixing belt 30 is detachably connected to the connecting portion 11. The pressure detecting member 40 is arranged in the middle part of the pole fixing belt 30 to detect the pressure between the pole fixing belt 30 and the pole. The control member is respectively connected with the pressure detecting member 40 and the driving member 22 by signal to control the driving member 22 according to the detection result of the pressure detecting member 40 to drive the rotating drum 21 to rotate. When the detection result of the pressure detecting member 40 is greater than or equal to the preset pressure threshold, the control member controls the driving member 22 to stop working. When the detection result of the pressure detecting member 40 is less than the preset pressure threshold, the control member controls the driving member 22 to work so that the rotating drum 21 rotates to shorten the extension length of the pole fixing belt 30.

[0029] The anti-slip fence safety belt provided in this embodiment includes a wearing fixing belt 10, an adjustment mechanism 20, a pole fixing belt 30, a pressure detection component 40 and a control component. The wearing fixing belt 10 is put on the waist of the operator, and the second end of the pole fixing belt 30 is passed around the pole from the side of the pole away from the operator. The second end of the pole fixing belt 30 is connected to the connecting part 11. When working at high altitude, the pressure detection component 40 is used to detect the force between the pole fixing belt 30 and the pole. If the posture of the operator causes the waist force to relax, the pressure detection component 40 detects that the force between the pole fixing belt 30 and the pole is less than the preset pressure threshold, and the control component controls the driving component 22 to work, so that the rotating drum 21 rotates to The extended length of the pole fixing belt 30 is shortened, so that the pole fixing belt 30 is tightened to increase the acting force between the pole fixing belt 30 and the pole. If the pressure detection component 40 detects that the acting force between the pole fixing belt 30 and the pole is greater than or equal to the preset pressure threshold, the control component controls the driving component 22 to stop working, and the rotating drum 21 no longer rotates to fix the extended length of the pole fixing belt 30, thereby avoiding insufficient acting force between the pole fixing belt 30 and the pole, and avoiding the pole fixing belt 30 from sliding down relative to the pole. There is no need for operators to manually operate the pole fixing belt 30, which avoids operators frequently straightening the pole fixing belt 30 during high-altitude operations, thereby improving the concentration and work efficiency of operators and avoiding omissions or personal safety accidents.

[0030] like Figure 2As shown, the pressure detection component 40 includes a mounting shell 41, a buffer pad 42 and a first detection component 43. The mounting shell 41 has a belt threading channel, and the pole fixing belt 30 is inserted into the belt threading channel. The buffer pad 42 is arranged on the side of the mounting shell 41 facing the pole. The first detection component 43 is arranged in the mounting shell 41 and detects the deformation of the buffer pad 42. During high-altitude operations, the buffer pad 42 is deformed under the action of the force between the pole fixing belt 30 and the pole. When the force between the pole fixing belt 30 and the pole is a preset pressure threshold, the deformation of the buffer pad 42 is a preset deformation threshold. During high-altitude operations, the first detection member 43 is used to detect the deformation of the buffer pad 42 to indirectly detect the force between the pole fixing belt 30 and the pole. If the operator's posture causes the waist force to relax, the first detection member 43 detects that the deformation of the buffer pad 42 is less than the preset deformation threshold, and the control member controls the driving member 22 to work. If the first detection member 43 detects that the deformation of the buffer pad 42 is greater than or equal to the preset deformation threshold, the control member controls the driving member 22 to stop working.

[0031] Specifically, the buffer pad 42 is made of silicone material.

[0032] like Figure 2 As shown, the buffer pad 42 is an annular structure, the inner side wall of the annular structure and the side wall of the mounting shell 41 facing the pole are arranged to form an adsorption chamber 44, the mounting shell 41 has a suction port 411 connected to the adsorption chamber 44, and the anti-slip pole safety belt also includes a vacuum pumping member arranged in the mounting shell 41 and connected to the suction port 411. When the acting force between the pole fixing belt 30 and the pole is greater than or equal to the preset pressure threshold, the outer side wall of the pole seals the opening of the annular structure facing the pole, and at this time, the vacuum pumping member can vacuum the adsorption chamber 44 through the suction port 411, so that the pressure detection member 40 is adsorbed and fixed on the pole.

[0033] like Figure 1 As shown, the anti-slip pole safety belt also includes a switch valve disposed in the mounting shell 41, and the switch valve has an open state connecting the adsorption chamber 44 with the outside world and a closed state isolating the adsorption chamber 44 from the outside world. When the pressure detection component 40 needs to be removed from the pole, the switch valve is switched to the open state, so that the adsorption chamber 44 is deflated, and the adsorption between the pressure detection component 40 and the pole is released. When the switch valve is switched to the closed state, and the acting force between the pole fixing belt 30 and the pole is greater than or equal to the preset pressure threshold, the adsorption chamber 44 can be evacuated by the vacuum element, so that the pressure detection component 40 is adsorbed and fixed on the pole.

[0034] Among them, the switch valve can be manually controlled or signal controlled.

[0035] like Figure 1As shown, the adjustment mechanism 20 includes a release button 23, a limit member 26 and a stroke detection member 27. The release button 23 is connected to the switch valve signal. When the release button 23 is pressed, the switch valve switches to an open state. When the release button 23 is released, the switch valve switches to a closed state. The limit member 26 has a avoidance state that allows the rotating drum 21 to rotate and a limit state that restricts the rotation of the rotating drum 21. The stroke detection member 27 can detect the rotation stroke of the rotating drum 21. The control member is respectively connected to the stroke detection member 27 and the limit member 26 signals. When the stroke detection member 27 detects that the rotation stroke of the rotating drum 21 reaches a preset maximum stroke, the control member controls the limit member 26 to switch to the limit state. When the stroke detection member 27 detects that the rotation stroke of the rotating drum 21 does not reach the preset maximum stroke, the limit member 26 switches to the avoidance state. Press the release button 23 to switch the switch valve to the open state, release the adsorption between the pressure detection component 40 and the pole, and the operator climbs up and down the pole. When the operator reaches the working height, release the release button 23 to switch the switch valve to the closed state. The operator leans back relative to the pole so that the force between the pole fixing belt 30 and the pole is greater than or equal to the preset pressure threshold. The adsorption chamber 44 can be evacuated by using the vacuum component to allow the pressure detection component 40 to be re-adsorbed and fixed on the pole.

[0036] like Figure 1 As shown, the adjustment mechanism 20 also includes a transmission member and an adjustment button 25. The transmission member is movably arranged between the driving member 22 and the rotating drum 21. The transmission member has a transmission position and a separation position. When the transmission member is in the transmission position, the driving member 22 and the transmission member are drivingly connected, and the transmission member and the rotating drum 21 are drivingly connected. When the transmission member is in the separation position, the transmission member is separated from the driving member 22 and the rotating drum 21 respectively, and the adjustment button 25 is drivingly connected to the transmission member. When the adjustment button 25 is pressed, the transmission member moves to the separation position. When the adjustment button 25 is released, the transmission member moves to the transmission position. When the operator climbs up and down the pole, the acting force between the pole fixing belt 30 and the pole is less than the preset pressure threshold. After the rotating drum 21 rotates to the preset maximum stroke, the limit member 26 limits the rotation of the rotating drum 21 to prevent the pole fixing belt 30 from continuing to tighten and affecting the climbing up and down the tower. When the operator reaches the working height, the release button 23 is released, the adjustment button 25 is pressed, and the transmission member moves to the separation position. The operator leans back relative to the pole to adjust the posture, and the rotating drum 21 is reversed to extend the pole fixing belt 30 relative to the adjustment mechanism 20. When the posture is adjusted to the right position, the adjustment button 25 is released, the transmission member moves to the transmission position, and the driving member 22 can drive the rotating drum 21 to rotate through the transmission member to tighten the pole fixing belt 30.

[0037] like Figure 1As shown, the pressure detection member 40 further includes a second detection member 45 , which is disposed in the mounting shell 41 and communicated with the suction port 411 to detect the negative pressure condition in the adsorption chamber 44 . When the force between the pole fixing belt 30 and the pole is greater than or equal to the preset pressure threshold, the outer wall of the pole seals the opening of the annular structure toward the pole, and the vacuum pump can vacuum the adsorption chamber 44 through the suction port 411. When the force between the pole fixing belt 30 and the pole is less than the preset pressure threshold, the outer wall of the pole cannot seal the opening of the annular structure toward the pole, and the vacuum pump cannot vacuum the adsorption chamber 44. Therefore, when working at high altitude, the second detection component 45 is used to detect the negative pressure in the adsorption chamber 44 to indirectly detect the force between the pole fixing belt 30 and the pole. When the vacuum pump is working, if the posture of the operator causes the waist force to relax, the second detection component 45 detects that the air pressure in the adsorption chamber 44 is less than the negative pressure domain value, and the control component controls the driving component 22 to work. If the second detection component 45 detects that the air pressure in the adsorption chamber 44 is greater than or equal to the negative pressure domain value, the control component controls the driving component 22 to stop working.

[0038] like Figure 1 As shown, the mounting shell 41 includes a shell 412 and two belt-threading rings 413, the two belt-threading rings 413 are respectively arranged at both ends of the shell 412, the inner holes of the two belt-threading rings 413 are connected to form a belt-threading channel, the pole fixing belt 30 is inserted through the inner holes of the two belt-threading rings 413, the buffer pad 42 is arranged on one side of the shell 412, the pole fixing belt 30 is wound around the side of the shell 412 away from the buffer pad 42, and the first detection member 43 is arranged in the shell 412. With the above structure, by sequentially inserting the pole fixing belt 30 into the two belt-threading rings 413, and the pole fixing belt 30 is wound around the side of the shell 412 away from the buffer pad 42, the mounting shell 41 can be conveniently and quickly installed on the pole fixing belt 30.

[0039] Furthermore, the mounting shell 41 can be slidably adjusted in position on the pole fixing belt 30 .

[0040] like Figure 1 As shown, the pressure detection member 40 further includes a buffer layer 46, which is filled between the mounting shell 41 and the first detection member 43. The buffer layer 46 is used to provide buffer protection for the first detection member 43, thereby preventing impact damage between the first detection member 43 and the mounting shell 41. Specifically, the buffer layer 46 is made of a buffer material, polypropylene plastic foam.

[0041] In this embodiment, the buffer pad 42 is detachably disposed on the mounting shell 41 . When the buffer pad 42 is aged due to long-term use or is worn by the electric pole, maintenance is facilitated by disassembling and assembling the buffer pad 42 .

[0042] Specifically, a card block is provided on the side of the buffer pad 42 facing the mounting shell 41, and a card slot is provided on the side of the mounting shell 41 facing the buffer pad 42. The card block and the card slot are snap-fitted together to facilitate quick disassembly and assembly of the buffer pad 42, and enable the buffer pad 42 to be reliably mounted on the mounting shell 41, thereby preventing the buffer pad 42 from falling off during normal use.

[0043] like Figure 1 As shown, the adjustment mechanism 20 also includes a mounting seat 281 and a belt pressing member 282. The mounting seat 281 is fixedly arranged on the wearing fixing belt 10, the rotating drum 21 and the driving member 22 are both arranged in the mounting seat 281, and the belt pressing member 282 is movably arranged on the mounting seat 281. The belt pressing member 282 has a locked state connected to the wearing fixing belt 10 and an unlocked state separated from the wearing fixing belt 10.

[0044] Specifically, the mounting seat 281 has a belt threading piece 2811, and the wearing and fixing belt 10 is inserted into the belt threading piece 2811. The belt pressing piece 282 has a puncture needle 2811. When the belt pressing piece 282 is in a locked state, the puncture needle 2811 is inserted into the wearing and fixing belt 10.

[0045] like Figure 1 As shown, the adjustment mechanism 20 also includes a switch button, the driving member 22 has a power-on state and a power-off state, and the pressure detecting member 40 also has a power-on state and a power-off state. The switch button is respectively connected to the driving member 22 and the pressure detecting member 40 by signal. When the switch button is long pressed, the driving member 22 and the pressure detecting member 40 are both switched to the power-on state. When the switch button is double-clicked, the driving member 22 and the pressure detecting member 40 are both switched to the power-off state.

[0046] like Figure 1 As shown, the adjustment mechanism 20 also includes a pole fixing belt 30 including a single-layer belt 31, a double-layer belt 32 and an adjustment buckle 33. The first end of the single-layer belt 31 is connected to the adjustment mechanism 20, the first end of the double-layer belt 32 is connected to the second end of the single-layer belt 31, the middle part of the double-layer belt 32 is detachably connected to the connecting part 11, and the adjustment buckle 33 is slidably mounted on the single-layer belt 31, and the adjustment buckle 33 is connected to the second end of the double-layer belt 32. Since the adjustment mechanism 20 has a stroke detection member 27 and a limit member 26, the adjustment mechanism 20 can only adjust the extension length of the pole fixing belt 30 within a range less than or equal to a preset maximum stroke. The preset maximum stroke is a parameter setting based on the posture change of the operator. The adjustment buckle 33 is slid on the single-layer belt 31, and the length of the pole fixing belt 30 can be adjusted within a range greater than the preset maximum stroke to meet the use requirements of poles of different diameters and adjust the distance between the operator and the pole.

[0047] like Figure 1As shown, the adjustment mechanism 20 also includes a connecting portion 11 including a clasp, which is fixedly connected to the wearing fixing belt 10, and a buckle 34 is provided at the second end of the pole fixing belt 30, and the buckle 34 is detachably connected to the clasp. By changing the connection state between the buckle 34 and the clasp, the connection state between the second end of the wearing fixing belt 10 and the connecting portion 11 is changed, which has the advantages of simple structure, easy operation and low cost.
