Description

Technical Field

[0001] The invention relates to a trackless fall arrester for a climbing tower, belonging to the technical field of transformer substation security. Background Art

[0002] With the continuous advancement of science and technology, people's demand for electricity is also increasing rapidly. In order to ensure the smooth flow of power grid arteries, ensure the safety and stability of tower structures, and inspect and repair potential problems to ensure the normal operation of power transmission and communication facilities, climbing towers for maintenance is an essential and major measure.

[0003] The main steps of tower climbing maintenance include planning and preparation, understanding safety measures, tower climbing, equipment inspection, cleaning and maintenance, and recording and reporting. The tower climbing step specifically involves using appropriate tools and equipment to enable workers to climb the tower to perform maintenance work.

[0004] However, the current transmission towers are very high, and climbing the towers will consume a lot of physical strength of the workers. At the same time, in order to ensure the installation, the workers need to use safety belts alternately during the climbing process to prevent themselves from falling to ensure their personal safety. However, in the process of climbing the towers and alternating the use of safety belts, it will inevitably bring more physical burden to the maintenance workers who climb the towers. Excessive physical exertion poses a greater risk to the safety of the maintenance workers who climb the towers, and buries safety hazards. In addition, the current transmission line towers are generally not equipped with anti-fall rails. Reinstalling the anti-fall rails will result in large investments and a long time consumption, so it is difficult to achieve results in a short period of time.

[0005] The Chinese invention patent with publication number CN111591932A discloses a manned lifting system and method for a power transmission line along an anti-fall track. The system includes a tower climbing robot, a lifting device, a lifting rope and a manned device; the tower climbing robot includes a lifting device, a pushing device and a hinge mechanism; the lifting device includes a floating frame, a telescopic cylinder and an upper lifting truss, the upper lifting truss is engaged with the anti-fall track, the top is hinged to the telescopic cylinder, the other end of the telescopic cylinder is connected to the floating frame, and the floating frame is hinged to the hinge mechanism; the pushing device includes a sliding seat, a telescopic cylinder and a pushing truss, the sliding seat and the pushing truss are both engaged with the anti-fall track and can slide along the length of the track, one end of the telescopic cylinder is hinged to the top of the pushing truss, and the other end is connected to the sliding seat, and the sliding seat is connected to the hinge mechanism; two tower climbing robots are installed on the anti-fall track in an upper and lower position; the manned device is assembled on the anti-fall track and is located below the tower climbing robot, the lifting device is connected to the manned device, one end of the lifting rope is connected to the lifting device, and the other end is connected to the tower climbing robot.

[0006] The above reference example performs manned lifting by installing a tower climbing robot on an anti-fall track. However, the installation of the anti-fall track is relatively expensive, and most of the pole towers are not installed with it at present, making it difficult to achieve full coverage of the pole towers. Therefore, improvement is urgently needed. Summary of the Invention

[0035] The present invention will be described in more detail below with reference to the embodiments.

[0036] Example 1

[0037] See also Figure 1 、 Figure 2 and Figure 3 The trackless fall arrester for the climbing tower of this embodiment includes an anti-fall block 1, a strong magnetic adsorption device is provided on one side of the anti-fall block 1, and one-way clamping mechanisms 2 for movably sleeved on the tower body of the climbing tower are provided at both ends of the anti-fall block 1. The clamping end of the one-way clamping mechanism 2 and the strong magnetic adsorption device are provided on the same side of the anti-fall block 1, and a plurality of movable wheels 103 are movably embedded on the surface of the strong magnetic adsorption device; a side of the anti-fall block 1 away from the strong magnetic adsorption device is movably connected to a suspension rope connected to a safety belt.

[0038] Specifically, in this embodiment, four moving wheels 103 are provided, and the four moving wheels 103 are arranged in a rectangular shape.

[0039] The anti-fall block 1 is a kind of anti-fall block which is used to prevent people from falling and has a good effect on climbing.

[0040] Furthermore, the anti-fall block 1 is a rectangular plate structure.

[0041] It can be seen from the above description that the rectangular plate structure is easy to process and suitable for promotion and use.

[0042] Example 2

[0043] The trackless fall arrester for climbing towers of this embodiment is further limited to the overall mechanical connection relationship of the one-way clamping mechanism 2 on the basis of the above-mentioned embodiment 1 as follows:

[0044] See also Figure 4 、 Figure 5 and Figure 6 The one-way clamping mechanism 2 includes an articulated clamping mechanism 3 and an installation component for driving the articulated clamping mechanism 3 to open or clamp; the installation component includes a mounting block 201, a fixed block 202, a mounting frame 203 and a U-shaped limit rod 204; mounting frames 203 are fixed at both ends of the mounting block 201, and the free end of the mounting frame 203 is fixedly connected to the anti-fall block 1. A through groove 104 is provided on the anti-fall block 1 at a position corresponding to the mounting block 201, and one end of the fixed block 202 is set close to the through groove 104. , the other end is fixed on the mounting block 201, and the fixing block 202 is arranged between the two mounting frames 203, the articulated clamping mechanism 3 is arranged in the through groove 104 and is movably hinged to the fixing block 202; the U-shaped limit rod 204 is slidably embedded in the fixing block 202 and the two ends of the U-shaped limit rod 204 are arranged in a direction away from the fixing block 202, the U-shaped limit rod 204 is driven to move by the stretching rebound mechanism, and the articulated clamping mechanism 3 is slidably connected to the two ends of the U-shaped limit rod 204 respectively.

[0045] Furthermore, the stretching rebound mechanism includes a push rod 205, one end of which is fixedly connected to the end cover plate 4, and a spring 5 is fixedly connected between the end cover plate 4 and the mounting block 201. The spring 5 is sleeved on the outside of the push rod 205 and the two ends of the spring 5 are respectively fixedly connected to the end cover plate 4 and the mounting block 201. The other end of the push rod 205 moves through the fixed block 202 and the mounting block 201 in turn and is fixedly connected to the U-shaped limit rod 204.

[0046] Furthermore, the articulated clamping mechanism 3 includes a pair of clamping rods 301, one end of the two clamping rods 301 is hinged to the free end of the fixed block 202 through the same hinge pin 304, and the other ends of the two clamping rods 301 are clamped together; a guide groove 302 is also provided on the clamping rod 301, and a guide rod 305 is movably provided in the guide groove 302, and one end of the guide rod 305 extends out of the guide groove 302 and is connected to one end of the U-shaped limit rod 204.

[0047] From the above description, it can be known that the hinged clamping mechanism 3 can be opened or clamped by setting the mounting assembly. Specifically, in the normal state, the two clamping rods 301 are in the clamping state. When it needs to be opened, the end cover plate 4 is pulled, and the end cover plate 4 drives the push rod 205 to move. The movement of the push rod 205 drives the U-shaped limit rod 204 to move under the limiting action of the fixed block 202, thereby making the two ends of the U-shaped limit rod 204 move, and then the movement of the guide rod 305 in the guide groove 302 can drive the two clamping rods 301 to swing open, thereby realizing the state of loosening the tower body. When clamping is required, the end cover plate 4 is loosened, and the push rod 205 returns to its original position under the action of the spring 5, thereby driving the clamping rod 301 to clamp;

[0048] Through the mutual cooperation of various components, the staff can open the clamping rod 301 conveniently and easily, and the clamping rod 301 is always in a clamped state when falling or in a normal state, which is convenient for the staff to operate and can effectively ensure the staff's work safety, greatly improving the applicability, and does not require the use of anti-fall slide rails, saving time and effort.

[0049] Furthermore, the butt joint surfaces of the two clamping rods 301 at one end of the clamping rods 301 are respectively provided with meshing teeth that cooperate with each other.

[0050] As can be seen from the above description, by providing the mutually cooperating adhesive teeth, the friction force when the two clamping rods 301 are clamped is increased, which effectively prevents slippage and further ensures safety.

[0051] Furthermore, the fixing block 202 is a triangular plate structure, and a slot is provided at one end of the fixing block 202 close to the hinged clamping mechanism 3 , and the U-shaped limiting rod 204 is slidably installed in the slot.

[0052] Specifically, the free end of the fixing block 202 is provided with a rounded corner, and the clamping rod 301 is hinged to the free end of the fixing block 202 via a hinge pin 304 .

[0053] From the above description, it can be seen that by setting the fixed block 202 as a triangular plate structure, the overall weight of the device can be effectively reduced, lightweight, and convenient positioning and connection. The U-shaped limit rod 204 is set in the slot, which can achieve the limitation of the U-shaped limit rod 204, so that the U-shaped limit rod 204 can only move along the direction of the slot, thereby ensuring the stability of the transmission.

[0054] Example 3

[0055] The trackless fall arrester for the climbing tower of this embodiment is further limited to the overall mechanical connection relationship of the fall arrester block 1 on the basis of the above-mentioned embodiment 1 or embodiment 2 as follows:

[0056] See also Figure 1 、 Figure 3 and Figure 7 A placement groove 101 is provided on the side of the anti-fall block 1 away from the strong magnetic adsorption device, and a fixing bar 102 is detachably connected to the placement groove 101. The lifting rope is sleeved on the fixing bar 102. An installation gap is provided between the inner side of the fixing bar 102 and the inner end of the placement groove 101, and an installation groove 1021 is provided on the inner side of the fixing bar 102. The installation groove 1021 is provided along the length direction of the anti-fall block 1, and an adjustment alarm device 6 is installed in the installation groove 1021 for alarming when the climber falls and the lifting rope is tightened.

[0057] From the above description, it can be seen that the setting of the fixing bar 102 is used to bind the sling, and the sling is used to connect the safety belt on the operator to ensure personal safety. By adjusting the setting of the alarm device 6, the corresponding safety person in charge can be notified in time that a person has fallen, and then the situation can be confirmed, such as whether rescue is needed, etc., to further ensure the personal safety of the operator.

[0058] Furthermore, the adjustment alarm device 6 includes a number of locking units arranged along the length direction of the installation groove 1021, and the locking unit includes a locking rod 601, a rotating pin 602 and a torsion spring 603. The rotating pin 602 is fixedly connected to one end of the locking rod 601, and the rotating pin 602 is rotatably installed in the installation groove 1021. The rotating pin 602 is outerly provided with a torsion spring 603 for driving the rotating pin 602 to return to its position; the other end of the locking rod 601 is arranged close to the inner wall of the placement groove 101, and a pressure sensor 604 is also provided on the inner wall of one end of the placement groove 101. The pressure sensor 604 is externally connected to the upper computer, and the hanging rope is set on the end of the fixing bar 102 away from the pressure sensor 604.

[0059] In particular, in order to ensure stable triggering of the pressure sensor 604 and prevent false triggering, when the anti-fall block 1 is installed, the end where the pressure sensor 604 is provided needs to be set at the lower end.

[0060] From the above description, it can be seen that the specific triggering process of the adjustment alarm device 6 is that when a person falls, the lifting rope will be pulled, and the clamping rod 601 will be turned, and the lifting rope will fall onto the next clamping rod 601. Since the force when a person falls is large, all the clamping rods 601 will be turned in turn, and then the pressure sensor 604 will be pulled. When the pressure sensor 604 senses the pressure, it will send an instruction to the upper computer to remind the safety person that a person has fallen. The setting of the torsion spring 603 can prevent the lifting rope from being separated from the restriction of the clamping rod 601 due to its own weight or the pulling of the operator during the climbing process, and accidentally touching the pressure sensor 604, thereby ensuring the accuracy of monitoring.

[0061] Furthermore, the placement groove 101 is opened between the two one-way clamping mechanisms 2 , and the placement groove 101 is opened in the middle position of one side of the anti-fall block 1 .

[0062] As can be seen from the above description, by opening the placement groove 101 in the middle position of one side of the anti-fall block 1, it is possible to effectively prevent interference with the one-way clamping mechanism 2 when connecting the safety belt, thereby ensuring smooth connection.

[0063] Example 4

[0064] The trackless fall arrester for climbing towers of this embodiment, based on the above-mentioned embodiment 1, embodiment 2 or embodiment 3, further defines the overall mechanical connection relationship of the strong magnetic adsorption device as follows:

[0065] See also Figure 8 、 Figure 9 and Figure 10 ,like Figure 1 As shown, a receiving groove 106 is provided at the bottom end of the anti-fall block 1 located between the two one-way clamping mechanisms 2, and the strong magnetic adsorption device includes a pair of strong magnetic bonding plates 105 movably installed inside the receiving groove 106, the two strong magnetic bonding plates 105 are hinged to each other, and a number of arc springs 109 that are always in a compressed state are arranged between the two strong magnetic bonding plates 105; both ends of the strong magnetic bonding plates 105 are fixedly connected to a fixed slide rod 108, and the inner side wall of the receiving groove 106 is provided with the same number of arc slide grooves 107 as the fixed slide rod 108, and the free end of the fixed slide rod 108 is slidably clamped inside the arc slide groove 107.

[0066] Specifically, in this embodiment, two moving wheels 103 are provided on each of the two strong magnetic laminating plates 105 .

[0067] From the above description, it can be seen that by setting the mutually hinged strong magnetic bonding plates 105, the strong magnetic bonding plates 105 can form a certain angle, and then can be more adapted to the shape of the climbing tower, so that the device fits the tower more closely, further improving the applicability of the device. At the same time, by setting the fixed slide bar 108 and the arc-shaped slide groove 107, the strong magnetic bonding plates 105 will not separate from the anti-fall block 1, thereby improving the safety of the operators during the climbing process. The setting of the arc spring 109 enables the two strong magnetic bonding plates 105 to always be in a trend of approaching each other, and the magnetic force of the strong magnetic bonding plates 105 can further fit the tower, making it convenient for operators to climb up and down and move easily.

[0068] The working principle of the present invention: The purpose of the present invention is mainly to provide reliable protection for workers in the process of climbing the pole tower. They only need to hold the main material of the pole tower with the one-way clamping mechanism 2 and connect the safety belt with the lifting rope to start climbing the pole tower. The present invention is convenient to use and does not bring additional burden to the workers in climbing the pole tower. It not only ensures the safety of the workers in the process of climbing the pole tower, but also improves the efficiency of the workers in climbing the pole tower, reduces the cost of installing the anti-fall track, and achieves the purpose of reducing costs and increasing efficiency.
