Description

Technical Field

[0001] The invention belongs to the technical field of power tower transmission line maintenance, and in particular relates to a new safety protection device for climbing a power tower. Background Art

[0002] During the maintenance work of power tower transmission lines, workers need to climb to the top of the tower and then pass through the tower crossarm to enter the work site. At present, in the process of high-altitude tower climbing, the protection methods commonly used by workers include rail-type climbing fall protection and double safety belt alternating protection. The double safety belt method is to add a protective belt to the traditional safety belt to form a double safety belt. The two safety belts are used alternately for climbing to ensure that at least one safety belt can connect the human body to the tower during the climbing process to ensure that no falling accidents occur.

[0003] When the safety protection device on the safety belt worn by the current power workers is connected to the tower foot nails on the power tower, if the collar of the safety protection device is directly put on the tower foot nail, it is difficult for the collar of the safety protection device to be stably put on the tower foot nail. Once the collar is separated from the tower foot nail, the safety protection function for the power workers will be lost; and it is difficult to further improve the stability of the connection between the collar of the safety protection device and the tower foot nail by only using a set of structures for limiting the collar; at the same time, if the power workers accidentally lose their footing during the climbing process, the safety belt will exert a large downward force on the safety protection device on the tower foot nail, which can easily cause the safety protection device and the tower foot nail to slide, thereby reducing the stability of the connection between the safety protection device and the tower foot nail. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a power tower climbing safety protection device.

[0005] The technical solution adopted to solve the above technical problems is: a power tower climbing safety protection device, including a mounting body as a mounting carrier, a collar is installed on the top of the mounting body, and the collar is sleeved on the outside of the tower foot nail, a mounting groove is opened at the middle position of the mounting body, a connecting mechanism is arranged inside the mounting groove, clamping mechanisms cooperating with the connecting mechanism are symmetrically arranged on the top of both ends of the mounting body, driving mechanisms cooperating with the connecting mechanism are symmetrically arranged on both sides of the mounting body, limiting mechanisms cooperating with the driving mechanism are symmetrically arranged on both sides of the collar, and a fastening mechanism cooperating with the connecting mechanism is installed at one end of the mounting body.

[0006] Furthermore, the connecting mechanism includes four groups of sliding rods located inside the mounting groove, and the outer sides of the four groups of sliding rods are jointly sleeved with a sliding block, a strip plate is installed at the middle position of the bottom end of the sliding block, a square through groove is opened at the inner bottom of the mounting groove, the bottom end of the strip plate passes through the square through groove and is installed with an annular connecting piece, and a first return spring is sleeved on the outer side of the sliding rod, and the top and bottom ends of the first return spring are respectively fixedly connected to the sliding block and the inner bottom of the mounting groove.

[0007] Through the above technical solution, when the annular connecting member is subjected to a large downward force, the annular connecting member pulls the sliding block to slide downward on the sliding rod through the strip plate, and the first return spring is shortened under the force and stores elastic potential energy, thereby buffering the downward force exerted on the annular connecting member, thereby improving the tensile strength of the entire safety protection device when subjected to downward pulling force.

[0008] Furthermore, the clamping mechanism includes a fixed column, which is provided with two groups, and the two groups of fixed columns are symmetrically distributed at the middle position of the top of both ends of the mounting body, the outer side of the fixed column is sleeved with two groups of semicircular frames that cooperate with each other, and a torsion spring is sleeved at the middle position of the outer side of the fixed column, and the two ends of the torsion spring are respectively fixedly connected to the two groups of semicircular frames, and the bottom of the two groups of semicircular frames are installed with push-pull rods that cooperate with the sliding blocks.

[0009] Through the above technical solution, when the sliding block moves upward, the two groups of push-pull rods are pushed away from each other, so that the two groups of semicircular frames can be rotated and opened with the fixed column as the axis. The torsion spring is stressed and stores torque. After the sliding block no longer applies force to the two groups of push-pull rods, the torsion of the torsion spring forces the two groups of semicircular frames to rotate with the fixed column as the axis to form a complete annular ring and be put on the tower foot nails, thereby ensuring the stability of the ring after being put on the tower foot nails.

[0010] Furthermore, the driving mechanism includes racks located on both sides of the strip plate, and strip through holes connected to the interior of the mounting groove are symmetrically opened on both sides of the mounting body. A rotating shaft is arranged at the bottom end of the strip through hole, and an incomplete gear meshing with the rack is installed on the outer side of the rotating shaft, and a manual lever is installed on the outer side of the incomplete gear.

[0011] Through the above technical solution, the hands are held on the outside of the installation body, and then the two sets of manual rods are pressed. The transmission of the incomplete gears and racks is used to push the strip plate and the sliding block upward a little. During the process, the sliding block pushes the push-pull rod to drive the semicircular frame to rotate with the fixed column as the axis, so that the two pairs of semicircular frames can be unfolded. After releasing the pressure on the manual rod, the torsion of the torsion spring can allow the two sets of semicircular frames to be reunited into an annular ring fixed to the outside of the tower foot nails.

[0012] Furthermore, the limiting mechanism includes two groups of movable frames located on both sides of the ring, spring grooves are symmetrically opened at both ends of the inner side of the movable frames, two groups of sliding columns are symmetrically installed on both sides of the ring, and one end of the two groups of sliding columns on the same side passes through the spring groove and is installed with an anti-slip block, a second return spring is sleeved on the outer side of the sliding column, and the two ends of the second return spring are respectively fixedly connected to the ring and one end inside the spring groove, and arc grooves that cooperate with the semicircular frame are symmetrically opened at both ends of the inner side of the movable frame.

[0013] Through the above technical solution, when the annular connecting member is subjected to a downward force, the transmission of the incomplete gear and the rack is used to drive the two groups of manual rods to rotate upward with the rotating shaft as the axis, until the bottom ends of the two groups of manual rods are tightly against the outside of the moving frame and push the moving frame to slide on the sliding column, so that the arc groove is tightly against the outside of the semicircular frame, so that the two groups of semicircular frames can firmly form an annular ring and will not separate. At this time, the second return spring is forced to shorten and store elastic potential energy. When the manual rod is no longer in contact with the moving frame, the elastic potential energy of the second return spring can prevent the arc groove from being pressed against the outside of the semicircular frame.

[0014] Furthermore, the fastening mechanism includes a U-shaped frame located at the top end of one end of the mounting body, a trapezoidal movable block that cooperates with the tower foot nail is hinged at the middle position of the bottom of the U-shaped frame, a T-shaped plate is installed on the outer side of the trapezoidal movable block, two groups of connecting tension springs fixedly connected to the outer side of the mounting body are installed on the top end of the inner side of the T-shaped plate, and limit stops are symmetrically installed on the bottom ends of both sides of the T-shaped plate, a mounting plate is installed on one end of the sliding block close to the U-shaped frame, and a wedge block that cooperates with the T-shaped plate is installed on the top end of the outer side of the mounting plate, and a pushing block that cooperates with the limit stop is symmetrically installed on the bottom end of the outer side of the mounting plate.

[0015] Through the above technical scheme, by utilizing the tension of the connecting tension spring and the T-shaped plate, the top of the trapezoidal movable block can be pressed against the outside of the tower foot nail, so that the ring will not slide easily after being put on the outside of the tower foot nail. When the user presses the two sets of manual rods, the strip plate drives the sliding block to slide upward on the sliding rod. At this time, the pushing block on the mounting plate cooperates with the limit stopper to push the trapezoidal movable block to rotate and open with its hinge axis hinged with the U-shaped frame as the axis, so that the top of the trapezoidal movable block no longer presses against the outside of the tower foot nail. When the annular connecting part is subjected to a large downward force and drops to the lowest position, the wedge block on the mounting plate tightly presses against the bottom end of the inner side of the T-shaped plate, forcing the top of the trapezoidal movable block to tightly press against the outside of the tower foot nail, thereby ensuring the stability of the connection between the entire safety protection device and the tower foot nail.

[0016] Furthermore, limiting sliding blocks are symmetrically installed at the middle positions of the two ends of the strip plate, and limiting sliding grooves adapted to the limiting sliding blocks are symmetrically opened at the middle positions of the two ends in the square through groove.

[0017] Through the above technical solution, when the sliding block is lifted or lowered inside the installation groove, the strip plate also slides in the square through groove, and the limiting sliding block slides in the limiting sliding groove, which helps to improve the stability of the strip plate and the sliding block during the lifting process.

[0018] Furthermore, a mounting thread is provided at the top end of the outer side of the fixing column, and a limiting nut is provided at the top end of the outer side of the fixing column through the mounting thread.

[0019] Through the above technical solution, after unscrewing the limit nut with a tool, the semicircular frame and the torsion spring can be removed from the fixing column.

[0020] Furthermore, connecting bearings are symmetrically installed at the bottom of the two ends of the two groups of strip-shaped through holes, and the two ends of the outer side of the rotating shaft are fixedly connected to the inner rings of the two groups of connecting bearings on the same side.

[0021] Through the above technical solution, when the manual rod drives the rotating shaft and the incomplete gear to rotate, the connecting bearing helps to improve the stability of the rotation of the incomplete gear and the manual rod.

[0022] Furthermore, a rubber protective sleeve is sleeved on the outer side of the manual rod, and a groove cooperating with the manual rod is provided at a middle position on the outer side of the movable frame.

[0023] Through the above technical solution, the rubber protective cover can effectively improve the comfort of the user when pressing the manual lever, and when the manual lever is rotated to vertically upward, the top of the outer side of the manual lever is against the groove on the outer side of the mobile frame, thereby improving the stability of the manual lever applying force to the mobile frame. At this time, the rubber protective cover can also provide protection for the manual lever and the mobile frame, thereby reducing the collision damage between the manual lever and the mobile frame.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention can prevent the ring from sliding on the tower foot nail due to shaking after the ring is put on the tower foot nail by cooperating with the connecting mechanism and the clamping mechanism, thereby effectively improving the stability of the ring after it is put on the tower foot nail; (2) The present invention can stably connect the installation body with the tower foot nail by the fastening mechanism, and further prevent the ring from sliding after it is put on the tower foot nail by cooperating with the connecting mechanism and the clamping mechanism, thereby fully improving the stability of the connection between the entire safety protection device and the tower foot nail; (3) The present invention can prevent the ring from sliding on the tower foot nail by cooperating with the connecting mechanism and the clamping mechanism. The cooperation of the driving mechanism and the limiting mechanism, when the safety belt connected to the annular connector applies a downward force to the annular connector, the driving mechanism and the limiting mechanism can effectively limit the semicircular frame, so that the two pairs of semicircular frames can stably form two groups of annular rings and stably fit on the tower foot nails. Combined with the sleeve ring, the stability of the connection between the entire safety protection device and the tower foot nails can be greatly improved. At the same time, with the cooperation of the connecting mechanism and the fastening mechanism, the trapezoidal movable block can be tightly pressed against the bottom end of the outer side of the tower foot nail, thereby providing effective safety protection for power workers in the process of climbing the tower.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figure 1-Figure 9 and Figure 12-13As shown, a power tower climbing safety protection device of the present embodiment includes a mounting body 3 as a mounting carrier, a collar 2 is installed on the top of the mounting body 3, and the collar 2 is sleeved on the outside of the tower foot nail 1, a mounting groove 4 is opened at the middle position of the mounting body 3, and a connecting mechanism 5 is arranged inside the mounting groove 4, and the connecting mechanism 5 includes four groups of slide bars 501 located inside the mounting groove 4, and a sliding block 502 is sleeved on the outer side of the four groups of slide bars 501, and a strip plate 503 is installed at the middle position of the bottom end of the sliding block 502, a square through groove 508 is opened at the inner bottom of the mounting groove 4, and the bottom end of the strip plate 503 passes through the square through groove 508 and is installed with an annular connecting piece 505, and a first return spring 504 is sleeved on the outer side of the slide bar 501, and the top and bottom ends of the first return spring 504 are respectively connected to the sliding block 50 2 is fixedly connected to the inner bottom of the mounting groove 4, and limit sliders 506 are symmetrically installed at the middle positions of the two ends of the strip plate 503, and limit slide grooves 507 compatible with the limit sliders 506 are symmetrically opened at the middle positions of the two ends in the square through groove 508. First, the ring 2 at the top of the mounting body 3 is put on the outside of the tower foot nail 1 on the power tower, and then the safety belt on the power operator is connected to the annular connector 505. When the annular connector 505 is subjected to a large downward force, the annular connector 505 pulls the sliding block 502 to slide downward on the sliding rod 501 through the strip plate 503, and the first return spring 504 is shortened by force and stores elastic potential energy, which buffers the downward force on the annular connector 505, thereby improving the tensile strength of the entire safety protection device when subjected to downward pulling force.

When the sliding block 502 moves upward, the two groups of push-pull rods 603 are pushed away from each other, so that the two groups of semicircular frames 602 can be rotated and opened with the fixed column 601 as the axis. The torsion spring 604 is stressed and stores torque. After the sliding block 502 no longer applies force to the two groups of push-pull rods 603, the torsion of the torsion spring 604 forces the two groups of semicircular frames 602 to rotate with the fixed column 601 as the axis to form a complete annular ring and be put on the tower foot nail 1, thereby ensuring the stability of the ring 2 after being put on the tower foot nail 1.

[0030] like Figure 1-Figure 9 and Figure 12-14As shown, in this embodiment, the two sides of the mounting body 3 are symmetrically provided with a driving mechanism 7 that cooperates with the connecting mechanism 5, and the two sides of the collar 2 are symmetrically provided with a limiting mechanism 8 that cooperates with the driving mechanism 7. The driving mechanism 7 includes a rack 705 located on both sides of the strip plate 503, and the two sides of the mounting body 3 are symmetrically provided with a strip through hole 701 that is connected to the inside of the mounting groove 4. The bottom end of the strip through hole 701 is provided with a rotating shaft 702, and the outer side of the rotating shaft 702 is installed with an incomplete gear 703 that meshes with the rack 705, and the outer side of the incomplete gear 703 is installed with a manual lever 704. The bottoms of the two ends of the two groups of strip through holes 701 are symmetrically installed with connecting bearings, and the outer side of the rotating shaft 702 The two ends of the two sets of connecting bearings on the same side are fixedly connected, and the limiting mechanism 8 includes two sets of moving frames 802 located on both sides of the collar 2, and spring grooves 804 are symmetrically provided at both ends of the inner side of the moving frame 802. Two sets of sliding columns 801 are symmetrically installed on both sides of the collar 2, and one end of the two sets of sliding columns 801 on the same side passes through the spring groove 804 and is installed with an anti-dropping block 803. The outer side of the sliding column 801 is sleeved with a second return spring 805, and the two ends of the second return spring 805 are respectively fixedly connected to the collar 2 and one end inside the spring groove 804. The two ends of the inner side of the moving frame 802 are symmetrically provided with arc grooves 806 that cooperate with the semicircular frame 602. The outer side of the manual rod 704 is sleeved with a rubber The rubber protective cover is provided, and a groove cooperating with the manual rod 704 is provided in the middle position of the outer side of the movable frame 802. The hand is held on the outer side of the mounting body 3, and then the two sets of manual rods 704 are pressed. The transmission of the incomplete gear 703 and the rack 705 is used to push the strip plate 503 to move the sliding block 502 upward a little. During the process, the sliding block 502 pushes the push-pull rod 603 to drive the semicircular frame 602 to rotate around the fixed column 601 as the axis, so that the two pairs of semicircular frames 602 are unfolded. After releasing the pressure on the manual rod 704, the torsion force of the torsion spring 604 can make the two sets of semicircular frames 602 merge into an annular ring and fix it on the outer side of the iron tower foot nail 1, and when the annular connecting piece 505 is subjected to downward When the force is applied, the transmission of the incomplete gear 703 and the rack 705 is used to drive the two sets of manual rods 704 to rotate upward with the rotating shaft 702 as the axis, until the bottom ends of the two sets of manual rods 704 are tightly against the outside of the moving frame 802 and push the moving frame 802 to slide on the sliding column 801, so that the arc groove 806 is tightly against the outside of the semicircular frame 602, so that the two sets of semicircular frames 602 can firmly form an annular ring and will not separate. At this time, the second return spring 805 is forced to shorten and store elastic potential energy. When the manual rod 704 is no longer in contact with the moving frame 802, the elastic potential energy of the second return spring 805 can prevent the arc groove 806 from being against the outside of the semicircular frame 602.

[0031] like Figure 1-Figure 5 , Figure 12-13 and Figure 15-16As shown, a fastening mechanism 9 cooperating with the connecting mechanism 5 is installed at one end of the mounting body 3 of the present embodiment, and the fastening mechanism 9 includes a U-shaped frame 901 located at the top end of one end of the mounting body 3, and a trapezoidal movable block 902 cooperating with the iron tower foot nail 1 is hinged at the middle position of the bottom of the U-shaped frame 901, and a T-shaped plate 903 is installed on the outer side of the trapezoidal movable block 902, and two groups of connecting tension springs 904 fixedly connected to the outer side of the mounting body 3 are installed on the top of the inner side of the T-shaped plate 903, and limited stoppers 905 are symmetrically installed at the bottom ends of both sides of the T-shaped plate 903, and a mounting plate 906 is installed at one end of the sliding block 502 close to the U-shaped frame 901, and a wedge block 907 cooperating with the T-shaped plate 903 is installed on the top of the outer side of the mounting plate 906, and a pushing block 908 cooperating with the limited stopper 905 is symmetrically installed on the bottom end of the outer side of the mounting plate 906. The tension of the spring 904 cooperates with the T-shaped plate 903 to allow the top of the trapezoidal movable block 902 to rest against the outer side of the iron tower foot nail 1, so that the ring 2 will not slide easily after being sleeved on the outer side of the iron tower foot nail 1. When the user presses the two sets of manual rods 704, the strip plate 503 drives the sliding block 502 to slide upward on the sliding rod 501. At this time, the pushing block 908 on the mounting plate 906 cooperates with the limit stopper 905 to push the trapezoidal movable block 902 to rotate and open with its hinge axis hinged to the U-shaped frame 901 as the axis, so that the top of the trapezoidal movable block 902 no longer rests against the outer side of the iron tower foot nail 1. When the annular connecting member 505 is subjected to a large downward force and drops to the lowest position, the wedge block 907 on the mounting plate 906 tightly rests on the bottom end of the inner side of the T-shaped plate 903, forcing the top of the trapezoidal movable block 902 to rest tightly against the outer side of the iron tower foot nail 1.

[0032] The working principle of this embodiment is as follows. First, the safety belt on the power operator is connected to the annular connecting piece 505. Then, the power operator holds the outer side of the installation body 3 with one hand, and then presses the two sets of manual rods 704, forcing the strip plate 503 to drive the sliding block 502 to rise slightly inside the installation groove 4. During the process, the top of the sliding block 502 abuts against the two pairs of push-pull rods 603 and pushes the push-pull rods 603 to drive the semicircular frame 602 to rotate around the fixed column 601 as the axis. At this time, the two pairs of semicircular frames 602 are all unfolded, and the pushing block 908 cooperates with the limit stopper 905 to push the T-shaped plate 903 to rotate downward and open with its hinge axis hinged with the U-shaped frame 901 as the axis. Then, the ring 2 at the top of the installation body 3 is put on the outer side of the tower foot nail 1 on the power tower, and then the pressure on the manual rod 704 is released, so that the two pairs of semicircular frames 602 can be clamped on the outer side of the tower foot nail 1, and the top of the trapezoidal movable block 902 abuts against the bottom of the tower foot nail 1.
