Description

Technical Field

[0001] The invention relates to the technical field of safety rope hanging, in particular to a safety rope hanging rack. Background Art

[0002] The existing drone hanging point can refer to the patent application number CN2022109786230, which includes a hook frame and a locking piece rotatably connected to the upper end of the hook frame, and the lower end of the hook frame is used to connect the safety rope. During installation, the drone is connected to the hook frame, and the hook frame is lifted above the cross-arm angle steel, and the hook frame is lowered. The horizontal part of the cross-arm angle steel pushes the locking piece, and the locking piece rotates and clamps the cross-arm angle steel between the locking piece and the hook frame. One side of the locking piece contacts the side of the vertical part of the cross-arm angle steel, and the other side of the locking piece contacts the edge of the horizontal part of the cross-arm angle steel to prevent the hook frame from shaking on the cross-arm angle steel.

[0003] The shape of the existing drone hanging point locking parts is fixed, and can only lock the cross-arm angle steel of the corresponding vertical thickness and the horizontal width of the cross-arm angle steel. If the cross-arm angle steel model or production process is different, after the hook is hooked on the cross-arm angle steel, there is a gap between the locking part and the vertical part of the angle steel, and the hook is easy to shake on the cross-arm angle steel, causing safety hazards. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention provides a safety rope hanger having the advantage of strong work adaptability.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A safety rope hanger, comprising a hanger body and a locking device; the hanger body comprises a hanging beam, a first vertical support portion and a second vertical support portion; the first vertical support portion and the second vertical support portion are respectively vertically connected to the two ends of the hanging beam in the length direction and are both extended downward; a gap is provided between the first vertical support portion and the second vertical support portion for a cross arm angle steel to enter; the locking device comprises a top rod vertically movable on the first vertical support portion and a top rod driving mechanism for driving the top rod away from or close to the second vertical support portion; the top rod cooperates with the second vertical support portion to clamp the vertical portion of the cross arm angle steel.

[0007] By adopting the above technical solution, the safety rope hanger is placed on the cross arm angle steel from top to bottom, so that the cross arm angle steel enters the gap between the first vertical support part and the second vertical support part. At this time, the horizontal part of the cross arm angle steel is against the suspension beam, and then the top rod driving mechanism drives the top rod to move toward the second vertical support part. In this process, the safety rope hanger is driven to move horizontally relative to the cross arm angle steel until the top rod and the second vertical support part clamp the vertical part of the cross arm angle steel. In this way, the thickness change of the vertical part of the cross arm angle steel can be ignored, and the connection between the safety rope hanger and the tight cross arm angle steel can be achieved, and the connection is stable, so that the safety rope hanger has strong working adaptability.

[0008] Optionally, the push rod driving mechanism includes a push rod driving motor fixed on the suspension beam and a push rod driving gear fixed on the output shaft of the push rod driving motor; a movable avoidance groove is formed inside the push rod for the push rod driving gear to move; a push rod driving rack is formed on the side wall of the movable avoidance groove; and the push rod driving rack is meshed with the push rod driving gear.

[0009] By adopting the above technical solution, the push rod driving motor drives the push rod driving gear to rotate, and the push rod driving rack on the push rod meshing with the push rod can drive the push rod to move vertically on the first vertical support part, and the structure is simple.

[0010] Optionally, both sides of the bottom of the first vertical support portion are rotatably connected with pre-positioning rods; the other end of the pre-positioning rod is elastically movably arranged on the suspension beam; the pre-positioning rod is used to abut against one end of the horizontal portion of the cross arm angle steel away from the vertical portion.

[0011] By adopting the above technical solution, when the cross-arm angle steel enters the gap between the first vertical support part and the second vertical support part, due to the elastic swing of a pair of pre-positioning rods, the safety rope hanger can be moved relative to the cross-arm angle steel so that the vertical part of the cross-arm angle steel is against the second vertical support part. In this way, the connection speed of the safety rope hanger and the cross-arm angle steel is greatly improved through pre-positioning. At the same time, the gap between the first vertical support part and the second vertical support part is made larger relative to the width of the cross-arm angle steel, thereby adapting to cross-arm angle steels of different widths and having stronger work adaptability.

[0012] Optionally, it also includes a safety rope placement assembly; the safety rope placement assembly can be connected to the bottom of the first vertical support part and the bottom of the second vertical support part through a pin; the safety rope placement assembly is connected to one of the first vertical support part and the second vertical support part; the safety rope placement assembly includes a rotatably connected safety rope wheel.

[0013] By adopting the above technical solution, the presence of the safety rope wheel of the safety rope placement assembly facilitates the use of the safety rope; the safety rope placement assembly can be connected at the bottom of the first vertical support part or the bottom of the second vertical support part according to the situation, thereby improving work adaptability; in addition, a pin is used to connect the hanger body and the safety rope placement assembly, which makes the disassembly and assembly operations more convenient.

[0014] Optionally, it also includes a guide assembly; the guide assembly can be connected to the bottom of the first vertical support part and the bottom of the second vertical support part by bolts; the guide assembly is connected to one of the first vertical support part and the second vertical support part; the guide assembly includes a guide steel frame; the guide steel frame has an inclined guide part; the inclined guide part approaches the gap between the first vertical support part and the second vertical support part from bottom to top.

[0015] By adopting the above technical solution, when the safety rope hanger is descending, the inclined guide part of the guide steel frame can guide the movement of the entire safety rope hanger, thereby accelerating the cross arm angle steel to enter the gap between the first vertical support part and the second vertical support part, which is beneficial to improving the connection efficiency of the safety rope hanger and the cross arm angle steel.

[0016] Optionally, a lifting bracket is installed on the hanging beam; the lifting bracket is used to be hooked with a ring on the drone.

[0017] By adopting the above technical solution, the safety rope hanger can be raised and lowered by the drone through the connection between the ring on the drone and the lifting frame, without the need for manual climbing, which greatly improves work safety.

[0018] Optionally, the lifting and lowering frame includes a main lifting column perpendicular to the suspension beam and a lifting hook portion arranged on the side wall of the main lifting column; the lifting hook portion includes an upper lifting support block and a lifting limit rod; the lower part of the lifting limit rod approaches the main lifting column from bottom to top; the upper lifting support block is located between the main lifting column and the upper part of the lifting limit rod; the bottom of the main lifting column is formed with a connecting groove for the vertical insertion of a ring; a closing bolt is arranged between the upper openings of the connecting grooves; one end of the closing bolt is elastically rotatably connected to one side wall of the connecting groove, and the other end abuts against the upper swing limit column on the other side wall of the connecting groove; the closing bolt swings down due to the gravity of the ring to open the upper opening of the connecting groove; the closing bolt swings up due to the elastic force and abuts against the upper swing limit column.

[0019] When the safety rope hanger of the drone is lifted and connected with the cross arm angle steel, the ring on the drone is put on the lifting limit rod (upper) from bottom to top until it hooks the lifting support block. In this way, when the safety rope hanger is placed on the cross arm angle steel, the drone can drive the ring to descend and detach from the lifting limit rod, and the drone can be recovered; when the drone lifts the safety rope hanger and detaches from the cross arm angle steel, the drone drives the ring to enter the connecting groove, and the closing bolt is swung down by the gravity of the ring to open the upper opening of the connecting groove. When the ring completely passes through the closing bolt, the closing bolt is swung up by the elastic force and abuts against the upper swing limit column to close the upper opening of the connecting groove. Then the drone rises to make the ring hook the closing bolt, thereby driving the entire safety rope hanger to detach from the cross arm angle steel. In this process, the connection between the ring and the safety rope hanger is stable, and the safety rope hanger will not fall off accidentally, which greatly improves safety.

[0020] Optionally, a pair of ferrule guide rods are provided at the upper end of the main lifting column; the pair of ferrule guide rods are located on both sides of the upper end opening of the connecting groove; the upper part of the ferrule guide rods is close to the upper end opening of the connecting groove from top to bottom.

[0021] By adopting the above technical solution, a pair of ferrule guide rods can play a guiding role in the process of the ferrule entering the connecting groove, thereby accelerating the ferrule to enter the connecting groove and improving installation efficiency.

[0022] Optionally, the bottom of the lifting frame is slidably arranged along the length direction of the suspension beam; a limiting member is arranged on the bottom of the lifting frame; the limiting member is used to limit the relative sliding of the bottom of the lifting frame and the suspension beam.

[0023] By adopting the above technical solution, by changing the relative position of the lifting bracket and the bracket body, the center of gravity between the two can be changed, so that the first vertical support part and the second vertical support part of the bracket body can be kept in a vertical state as much as possible in the air, which is conducive to placing the bracket body on the cross arm angle steel and detaching from the cross arm angle steel.

[0024] Optionally, the lifting bracket is detachably connected to the hanging beam.

[0025] By adopting the above technical solution, when storage and transportation are required, the lifting frame can be disassembled from the hanging beam, thereby reducing the overall length and facilitating storage and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following combines the attached Figure 1-Figure 7 to further elaborate on the present invention in detail.

[0044] Embodiment 1: Disclose a safety rope hanger. Refer to Figure 1 , the hanger main body 10, the locking device 20, the lifting and hoisting frame 80 and the safety rope placement assembly 40; the hanger main body 10 includes a suspension beam 12, a first vertical support portion 11 and a second vertical support portion 13; the first vertical support portion 11 and the second vertical support portion 13 are respectively vertically connected to both ends of the suspension beam 12 in the length direction and both extend downward; the locking device 20 is arranged on the first vertical support portion 11 and is used to cooperate with the second vertical support portion 13 to clamp the vertical portion of the cross-arm angle steel 100; the safety rope placement assembly 40 is connected to either the bottom of the first vertical support portion 11 or the bottom of the second vertical support portion 13 and is used to hang the safety rope; the lifting and hoisting frame 80 is installed on the suspension beam 12 and is used to connect with the circular ring-shaped sleeve on the unmanned aerial vehicle; the sleeve is connected to the unmanned aerial vehicle through a connecting rope. In order to increase the storage capacity of the hanger main body 10, the hanger main body 10 is provided with a hollow interior and an inner opening, that is, it includes a pair of parallel front and rear baffles 114 with openings facing downward in a "U" shape and two side baffles 115; the two side baffles 115 are respectively fixed between the gaps at the lower ends of the horizontal portions of a pair of front and rear baffles 114 and between the gaps on the side of a pair of front and rear baffles 114 away from the second vertical support portion 13; in order to increase the strength of the hanger main body 10, a number of reinforcing rods 116 are arranged between a pair of front and rear baffles.

[0045] Refer to Figure 1 and Figure 2 , a top sliding guide rail 14 is fixed on the upper end surface of the suspension beam 12; the length direction of the top sliding guide rail 14 is parallel to the length direction of the suspension beam 12; the lifting and hoisting frame 80 includes a main lifting column 81, a lifting hook connecting portion and a bottom sliding block 82; the bottom sliding block 82 is fixed at the bottom of the main lifting column 81; the bottom sliding block 82 is slidably arranged on the top sliding guide rail 14 and the main lifting column 81 is arranged perpendicular to the top sliding guide rail 14.

[0046] Refer to Figure 2 , in order to prevent the bottom sliding block 82 from accidentally detaching from the top sliding guide rail 14, end limit columns 141 are respectively vertically and elastically telescopically arranged at both ends of the upper end surface of the top sliding guide rail 14; in the normal state, the end limit columns 141 protrude from the upper end surface of the top sliding guide rail 14, and at this time, the bottom sliding block 82 can be blocked from detaching from the top sliding guide rail 14, so that the lifting and hoisting frame 80 can be disassembled; during installation, press one of the end limit columns 141, and then block the bottom sliding block 82 to be sleeved onto the top sliding guide rail 14 from the side of the pressed end limit column 141.

[0047] refer to Figure 2 In order to limit the relative sliding of the bottom of the lifting frame 80 and the top sliding guide rail 14, a limiting member is provided on the bottom sliding block 82, and the limiting member is a limiting pin 88 elastically and telescopically arranged on the side wall of the bottom sliding block 82, and a limiting through-hole is formed on the side wall of the bottom sliding block 82 for the limiting pin 88 to pass through; an axial limiting block parallel to its axial direction is formed on the outer end of the cylindrical surface of the limiting pin 88; an axial sliding groove matching the axial limiting block is formed on the side wall of the limiting through-hole; a plurality of side limiting slots 140 evenly distributed along its length direction are formed on the side wall of the top sliding guide rail 14 near the limiting pin 88; the side limiting slots 140 are adapted to the inner end of the limiting pin 88. When it is necessary to slide the lifting and lowering rack 80, the limit pin 88 is pulled outward, at this time the axial limit block is disengaged from the axial sliding groove, and then the limit pin 88 is rotated to make the axial limit block and the axial sliding groove staggered, so that the limit pin 88 cannot move inward, and the lifting and lowering rack 80 can be slid. When the lifting and lowering rack 80 slides to a suitable position, the limit pin 88 is rotated back to make the axial limit block face the axial sliding groove, and then the limit pin 88 is released. Due to the elastic force, the limit pin 88 moves toward the top sliding guide rail 14 until it abuts against the side wall of the top sliding guide rail 14, and then the lifting and lowering rack 80 is appropriately moved. Due to the elastic force, the inner end of the limit pin 88 will be inserted into the nearest side limit slot 140, thus completing the limit of the lifting and lowering rack 80 and the top sliding guide rail 14. By adjusting the relative position of the lifting bracket 80 and the bracket body 10, the center of gravity of the entire safety rope bracket can be adjusted so that the first vertical support part 11 and the second vertical support part 13 can be kept in a vertical state as much as possible, which is convenient for connecting and disconnecting with the cross arm angle steel 100.

[0048] refer to Figure 2 The lifting hooking part is located on one of the end faces of the main lifting column 81 perpendicular to the length direction of the top sliding guide rail 14; the lifting hooking part includes a lifting support block 83 and a lifting limit rod 84; the lifting support block 83 is fixed on the end face of the main lifting column 81; the upper end of the lifting limit rod 84 is fixed on the end face of the lifting support block 83 away from the main lifting column 81, and the lower part is close to the main lifting column 81 from bottom to top; in order to ensure the connection stability between the ring and the lifting support block 83, an arc groove adapted to the ring is formed on the lower end face of the lifting support block 83. When the safety rope hanger needs to be lifted, the ring on the drone is set on the lower end of the lifting limit rod 84 from top to bottom until the lower end of the ring enters the arc groove of the lifting support block 83. The inclined part of the lifting limit rod 84 has the function of guiding and preventing the ring from accidentally detaching during the lifting process.

[0049] refer to Figure 2 and Figure 3In order to further improve the connection stability between the ring and the lifting frame 80, a connecting groove 810 for the ring to be vertically inserted is formed at the bottom of the main lifting column 81; a closing bolt 86 is arranged between the upper openings of the connecting groove 810; one end of the closing bolt 86 is elastically rotatably connected to a side wall of the connecting groove 810, and the other end abuts against an upper swing limit column 87 on the other side wall of the connecting groove 810; the closing bolt 86 swings down due to the gravity of the ring to open the upper opening of the connecting groove 810; the closing bolt 86 swings up due to the elastic force and abuts against the upper swing limit column 87 to close the upper opening of the connecting groove 810. In this way, when the entire safety rope hanger needs to be separated from the cross arm angle steel 100, the drone is controlled so that the ring enters the upper opening of the connecting groove 810. When it hits the closing bolt 86, the closing bolt 86 swings downward due to the gravity of the ring. When the ring passes through the closing bolt 86 and enters the lower part of the connecting groove 810, the closing bolt 86 is swung upward by the elastic force and presses against the upper swing limit column 87, thereby closing the upper opening of the connecting groove 810. In this way, when the drone is controlled to rise, the rising ring moves upward and presses against the closing bolt 86, thereby driving the entire safety rope hanger to rise and separate from the cross arm angle steel 100.

[0050] refer to Figure 2 and Figure 3 In order to facilitate manual operation of the closing bolt 86 to open the upper opening of the connecting groove 810, a manual operation column 861 is formed on the closing bolt 86, and an operation avoidance groove 811 for the manual operation column 861 to enter is formed on the side wall of the connecting groove 810 near the rotating end of the closing bolt 86.

[0052] refer to Figure 1 , Figure 4 and Figure 5 The locking device 20 includes a push rod 21 vertically movable on the first vertical support portion 11 and a push rod driving mechanism for driving the push rod 21 away from or close to the second vertical support portion 13. A vertical slide groove 112 for the push rod 21 to slide is formed on the side baffle of the first vertical support portion 11. In order to ensure the sliding stability of the push rod 21, a translation support plate 113 is formed at the bottom of the vertical slide groove 112. The push rod 21 slides on the part of the vertical slide groove 112 located on the upper side of the translation support plate 113.

[0053] refer to Figure 1 , Figure 4 and Figure 5The push rod driving mechanism includes a push rod driving motor 23 fixed on the suspension beam 12 and a push rod driving gear 24 fixed on the output shaft of the push rod driving motor 23; a movable avoidance groove for the push rod driving gear 24 to move is formed inside the push rod 21; a push rod driving rack 211 is formed on the side wall of the movable avoidance groove; the push rod driving rack 211 is meshed with the push rod driving gear 24.

[0054] During operation, the push rod driving motor 23 drives the push rod driving gear 24 to rotate, and drives the push rod 21 to move in the vertical slide slot 112 through the push rod driving rack 211 meshing therewith, until the top of the push rod 21 and the second vertical support portion 13 clamp the vertical portion of the cross arm angle steel 100. In order to improve the stability of clamping, a clamping abutment plate 22 is fixed to the end of the push rod 21 close to the second vertical support portion 13, and the clamping abutment plate 22 is used to increase the area of ​​the end of the push rod 21, thereby improving the stability of clamping.

[0057] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is: Figure 1 , Figure 4 , Figure 6 and Figure 7 In order to facilitate the cross-arm angle steel 100 to enter the gap between the first vertical support portion 11 and the second vertical support portion 13, a guide assembly 60 can be installed at either the bottom of the first vertical support portion 11 or the bottom of the second vertical support portion 13; the guide assembly 60 includes a pair of guide support plates 62 and a guide steel frame 61; the guide steel frame 61 has a pair of guide portions; the guide portions correspond one-to-one to the guide support plates 62; the guide portions are composed of a vertical fixing portion 611 and an inclined guiding portion 612; the vertical fixing portion 611 is fixed on the end surface of the guide support plate 62 close to the second vertical support portion 13; the inclined guiding portion 612 approaches the gap between the first vertical support portion 11 and the second vertical support portion 13 from bottom to top. In order to increase the strength of the guide steel frame 61, a transverse connecting portion 613 is formed between the ends of the pair of inclined guide portions 612 away from the vertical fixing portion 611; the bottoms of the pair of front and rear baffles of the first vertical support portion 11 and the second vertical support portion 13 are both formed with bottom threaded holes 111; bolts 63 are passed through the guide support plate 62, and the bolts 63 are screwed into the bottom threaded holes 111 on the corresponding sides. In order to increase the installation stability of the guide support plate 62, a pair of positioning plugs that match the connecting through holes 110 are respectively formed on the end surfaces of the pair of guide support plates 62 that are close to each other.

[0058] Embodiment 3: Embodiment 3 differs from Embodiment 1 in that: a wind speed sensor 70 is fixed on the end face of the first vertical support portion 11 away from the second vertical support portion 13; a humidity sensor 90 is fixed in the second vertical support portion 13; a camera 91 is fixed in the first vertical support portion 11, and the camera 91 is used to photograph the movement status of the top rod 21; a power supply device, a processor and a signal remote transmission device are provided in the safety rope hanger, and the power supply device is used to supply power to the processor, the signal remote transmission device, the humidity sensor 90 and the wind speed sensor 70, the camera 91 and the top rod drive motor 23.
