Description

Technical Field

[0001] The present application relates to the technical field of cement pole climbing and falling prevention, and in particular to an intelligent cement pole high-altitude falling prevention device. Background Art

[0002] At present, most of the cement poles in the intensive 35kV transmission lines do not have foot spikes and anti-fall devices. When climbing cement poles, workers basically rely on foot buckles to climb the poles. According to the power safety regulations, safety belts must be used for high-altitude operations, but using foot buckles to climb poles only involves wrapping the waist rope of the pole-type safety belt around the cement pole to climb up and down, but it cannot provide effective protection. If a worker accidentally falls from a high altitude while climbing a cement pole, the safety belt will slide down the cement pole and cannot provide protection, thus causing a personal production accident. The "Work Safety Law" requires that production and operation units must provide safe and reliable working conditions for workers. Therefore, it is necessary to develop and apply cement pole high-altitude fall arresters for climbing cement poles to ensure the safety of high-altitude operations and improve the management level of work safety. Summary of the invention

[0003] To solve the above problems, this application adopts the following technical solutions:

[0004] An intelligent cement pole high altitude anti-falling device, comprising:

[0006] The utility pole clamping device is fixedly arranged on the annular frame and can be extended and retracted along the radial direction of the annular frame to achieve clamping or loosening of the utility pole; since the diameters of utility poles, especially cement utility poles, are not the same, many utility poles adopt a tapered utility pole design with the pole tail smaller than the pole head. Therefore, the utility pole clamping device can be adjusted according to the diameter of the utility pole to ensure that the utility pole clamping device can always have sufficient contact force with the utility pole.

[0007] The walking device is fixedly arranged on the inner side of the utility pole clamping device, can abut against the utility pole and can rise or fall along the utility pole.

[0008] Preferably, a distance detection sensor is also provided, and the distance detection sensor is fixedly provided under the utility pole clamping device, and is used to detect the distance between the operator and the intelligent cement pole high altitude anti-fall device. One or more distance detection sensors can be provided, and non-contact sensors such as laser distance measuring sensors, ultrasonic distance measuring sensors, etc. are used. When the distance detection sensor detects that the operator is within the predetermined range, the operator performs the ascending or descending crawling.

[0009] Preferably, a safety control switch is also provided, and the safety control switch is fixedly provided on the annular frame. The safety control switch is a normally closed switch, which is connected in series in the entire electrical circuit, similar to the use of an emergency stop switch. When in use, the operator fastens the safety belt to the annular frame, and an elastic belt is provided on the safety belt, such as an elastic belt made of rubber or an elastic belt made of spring, etc., one end of the elastic belt is connected to the safety control switch. When a person falls, the elastic belt first pulls the safety control switch to open it, cuts off all current circuits, and locks the walking device so that it cannot move, thereby finally achieving the purpose of preventing falling.

[0020] After the three arc-shaped frames are spliced ​​into a ring frame, the screw rods on the three hand-cranked jacks are connected to the clamping motor through a flexible shaft.

[0023] The other end of the pressure sensing connection block is fixedly connected to the walking wheel bracket, and the walking wheel bracket has a C-shaped cross section, in which the first walking wheel and the second walking wheel are rotatably arranged;

[0024] The travel motor is fixedly arranged on one side of the travel wheel bracket;

When a fall occurs, the electromagnetic brake clamps the motor shaft, making the travel wheel unable to rotate, thereby clamping the pole. The electromagnetic brake device uses a power-off clamping method, and its control circuit is connected in series with the safety control switch and the power supply.

[0029] Preferably, the first running wheel and the second running wheel have the same structure, both of which are dumbbell structures with diameters at both ends larger than the middle diameter.

[0030] Preferably, connecting sleeves are staggered and fixedly provided on one side of two adjacent arc frames, and the connecting sleeves are fixedly provided on the arc frame connecting rods. The two adjacent arc frames are detachably connected by pins passing through the connecting sleeves.

[0046] like Figures 1 to 8 As shown, an intelligent cement pole high altitude anti-falling device comprises a ring frame 1, a pole holding device 2 and a walking device 3, wherein:

[0047] The ring frame 1 is a ring-shaped structure, which can be detachably arranged around the outer periphery of the electric pole to be climbed. Figure 5 As shown, the annular frame 1 is composed of three arc frames spliced ​​together, and the arc frames are one-third of a circle. The three arc frames have the same structure, and the three arc frames are hinged head to tail to form a complete ring. A pole clamping device 2 and a walking device 3 are provided on each of the arc frames. The pole clamping device 2 can be extended and retracted along the radial direction of the annular frame 1, so as to achieve the clamping or loosening of the pole. Since the diameters of poles, especially cement poles, are not the same, and the bottom diameter is often larger than the top diameter, the pole clamping device 2 is provided so that it can be adjusted according to the diameter of the pole, ensuring that the pole clamping device 2 can always have sufficient contact force with the pole. The walking device 3 can be against the pole and can rise or fall along the pole.

[0048] like Figures 5 to 8 As shown in FIG. 7 , the arc frame includes an upper arc rod 10 and a lower arc rod 11, and the arc and length of the upper arc rod 10 and the lower arc rod 11 are equal. The arc rod 10 and the lower arc rod 11 can be made of bent steel pipes. The upper arc rod 10 and the lower arc rod 11 are fixedly connected by an arc frame connecting rod 12.

[0049] like Figure 1 and Figure 4 As shown, a clamping motor 22 is fixedly arranged on the outer side of the arc frame connecting rod 12. After the three arc frames are spliced ​​into a ring frame 1, the screw rods 210 on the three hand-cranked jacks 21 are connected to the clamping motor 22 through a flexible shaft 23. This design can adjust three sets of telegraph pole clamping devices 2 at the same time with only one motor, which reduces the cost and simplifies the control difficulty.

[0050] like Figure 5 , 7As shown in Figures 8 and 9, the walking device 3 includes a pressure sensing connection block 30, a walking wheel bracket 31, a walking motor 32, a first walking wheel 33 and a second walking wheel 34. One end of the pressure sensing connection block 30 is fixedly connected to the hand jack 21. The pressure sensing connection block 30 is provided with a pressure detection unit, such as a sensor structure such as a strain gauge, which can detect the pressure between the walking device 3 and the electric pole under the action of the hand jack 21, and use this as reference information for controlling the clamping motor 22. The other end of the pressure sensing connection block 30 is fixedly connected to the walking wheel bracket 31. The cross section of the walking wheel bracket 31 is a C-shaped structure, in which the first walking wheel 33 and the second walking wheel 34 are rotatably arranged. The walking motor 32 is fixedly arranged on one side of the walking wheel bracket 31. The output shaft 320 of the walking motor 32 passes through the walking wheel bracket 31, and two driving sprockets 321 are fixedly mounted on the output shaft 320 on the other side of the walking wheel bracket 31. A first walking sprocket 330 is fixedly provided on one side of the first walking wheel 33, and the first walking sprocket 330 is connected to one of the driving sprockets 321 through a chain 35. A second walking sprocket 340 is fixedly provided on one side of the second walking wheel 34, and the second walking sprocket 340 is connected to the other driving sprocket 321 through a chain 35. Such a design can also realize that one walking motor 32 drives the movement of two walking wheels, saving costs. In addition, an electromagnetic brake device is also provided on the walking motor 32. The first walking wheel 33 and the second walking wheel 34 have the same structure, and both are dumbbell structures with diameters at both ends larger than the middle diameter. The electromagnetic brake device is used to prevent the walking motor 32 from malfunctioning. When a fall occurs, the electromagnetic brake clamps the motor shaft, so that the walking wheel cannot rotate, thereby clamping the electric pole. The electromagnetic brake device adopts a power-off clamping method, and its control circuit is connected in series with the safety control switch 5 and the power supply.

[0051] like Figure 3 and Figure 5 As shown, connecting sleeves 13 are staggered and fixedly arranged on one side of two adjacent arc frames, and the connecting sleeves 13 are fixedly arranged on the arc frame connecting rods 12. The two adjacent arc frames are detachably connected by pins 14 passing through the connecting sleeves 13.

[0052] In addition, the device is also provided with a distance detection sensor 4 and a safety control switch 5. Figure 5As shown, the distance detection sensor 4 is fixedly arranged below the pole clamping device 2, and is used to detect the distance between the operator and the intelligent cement pole high-altitude anti-fall device. The distance detection sensor 4 can be set to one or more, using a non-contact sensor, such as a laser distance sensor, an ultrasonic distance sensor, etc., and when it detects that the operator is within the predetermined range, it performs an ascending or descending crawling. The safety control switch 5 is fixedly arranged on the ring frame 1. The safety control switch 5 is a normally closed switch, which is connected in series in the entire electrical circuit, similar to the use of an emergency stop switch. When in use, the operator fastens the safety belt to the ring frame 1, and an elastic belt is set on the safety belt, such as an elastic belt made of rubber or an elastic belt made of spring, etc., one end of the elastic belt is connected to the safety control switch 5. When a person falls, the elastic belt first pulls the safety control switch 5 to open it, cuts off all current circuits, and makes the walking device 3 locked and unable to move, and finally achieves the purpose of anti-falling.

[0053] In addition, the device is also provided with a battery pack and a control circuit. The battery pack is fixed on the inner side of each arc frame. The control circuit includes a single-chip microcomputer, which is respectively connected to each motor and sensor for coordinating and controlling the movement of the entire device.

[0054] When working, three mutually hinged arc-shaped frame rings are set around the pole. Fig.10As shown, the three mutually hinged arc frames are aligned and fixed into a ring through the connecting sleeve 13 and the pin 14. Then, the control circuit controls the rotation of the clamping motor 22, and the output shaft of the clamping motor 22 is connected to the flexible shaft 23, and the flexible shaft 23 is respectively connected to the screw rods 210 on the three hand jacks 21, so that the telescopic distance of the hand jacks 21 can be adjusted synchronously. When the hand jack 21 is extended and moves toward the electric pole, the first running wheel 33 and the second running wheel 34 on the running device 3 contact the electric pole, and this basic pressure is transmitted back to the single-chip microcomputer through the pressure sensing connection block 30. The single-chip microcomputer controls the clamping motor 22 according to the pressure size, and always maintains a constant pressure with the electric pole. Such a design can be automatically adjusted according to the different diameters of the electric poles. After the pressure adjustment is completed, the single chip microcomputer controls the travel motor 32 to rotate, and the output shaft 320 of the travel motor 32 drives the two active sprockets 321 to rotate. The two active sprockets 321 drive the first travel sprocket 330 and the second travel sprocket 340 to rotate through the chain 35. The first travel sprocket 330 and the second travel sprocket 340 drive the first travel wheel 33 and the second travel wheel 34 to rotate, so that the device can be lifted and moved along the pole. When in use, the intelligent cement pole high-altitude anti-falling device is always located above the climber, and it detects the distance with the climber through the distance detection sensor 4, and automatically controls the intelligent cement pole high-altitude anti-falling device to always keep a certain distance from the climber. When a fall occurs, the safety belt first pulls open the safety control switch 5, cuts off the power circuit, and all motors cannot work. The electromagnetic brake holds the motor shaft tightly, so that the automatic control intelligent cement pole high-altitude anti-falling device tightly holds the pole, providing a force for the climber to prevent it from falling.

[0055] The present application discloses an intelligent cement pole high-altitude anti-fall device, including a ring frame 1, a pole clamping device 2 and a walking device 3, wherein the ring frame 1 is a ring-shaped structure, which can be detachably arranged around the outer periphery of the pole to be climbed, the pole clamping device 2 is fixedly arranged on the ring frame 1, and can be extended and retracted along the radial direction of the ring frame 1, so as to achieve the clamping or loosening of the pole, and the walking device 3 is fixedly arranged on the inner side of the pole clamping device 2, and can be against the pole and can rise or fall along the pole. By putting the walking device 3 on the outer periphery of the pole through the ring frame 1, it can be moved up or down as needed and the pole clamping device 2 can be used to clamp the pole to prevent falling accidents. The whole device has a reasonable design, ingenious structure, good stability, and is easy to carry, assemble and maintain.
