Description

Technical Field

[0001] The utility model belongs to the field of maintenance seats, in particular to a line maintenance seat. Background Art

[0002] As the name suggests, a utility pole is a pole for erecting power lines. The maintenance personnel on the pole wear a pair of foot buckles on both feet. They use the foot buckles to climb the utility pole alternately with their left and right feet. When they climb to the maintenance height of the utility pole, they start to repair the line. However, during the period of time when the maintenance personnel are repairing the line on the pole, their feet go up and down. Due to the inconsistent height of their feet, the maintenance personnel have one leg bent at the knee and the other leg straight, and the straight leg mainly supports the body. When the straight leg is tired, the maintenance personnel will switch the upper and lower positions of the left and right feet. The left and right feet need to be adjusted frequently, which consumes a lot of physical energy, resulting in long maintenance and inspection time on the pole, low work efficiency, and long inspection time required. Affecting the power supply, the China Patent Office issued an authorization announcement on October 4, 2022, with the patent with authorization announcement number CN217526286U: "Line Maintenance Footstepping Frame". The patent discloses a stepping frame, but when the device is in use, it is necessary to remove the foot from the foot buckle and place it on the footstepping frame. When the foot is removed from the foot buckle, the friction of the foot buckle will be reduced because the human body does not apply pressure to the foot buckle, which can easily cause the foot buckle to fall off the electric pole, making it impossible for the maintenance personnel to get down from the electric pole; in the process of moving the foot from the foot buckle to the foot stepping foot, the maintenance personnel will be at risk of falling. Therefore, we designed a line maintenance seat. Utility Model Content

[0003] The utility model provides a line maintenance stand to solve the defects in the prior art.

[0004] The utility model is realized through the following technical solutions:

[0005] A line maintenance stand comprises two transverse tubes, which are fixedly connected via vertical rods. The stand is characterized in that a first transverse rod is movably provided in the upper transverse tube, a plurality of sliders are fixedly installed on the first transverse rod, a slide groove is provided on the inner wall of the upper transverse tube corresponding to the sliders, the sliders are slidably installed in the corresponding slide grooves, an annular groove is provided on the inner wall of the upper transverse tube, the annular groove is connected with the slide groove, the sliders can slide into the annular grooves respectively, a second transverse rod is movably provided in the lower transverse tube, and the first transverse rod and the second transverse rod are fixedly connected via a U-shaped rod.

[0007] In the line maintenance stand as described above, two arc blocks are fixedly installed on the outer periphery of the upper cross tube, and an arc groove is provided on the outer periphery of the second cross bar.

[0008] In the line maintenance stand as described above, anti-skid rubber layers are fixedly installed on the arc-shaped block and the arc-shaped groove respectively.

[0009] In the track maintenance seat as described above, a safety belt is provided on one side of the vertical pole, and the safety belt is fixedly connected to the horizontal pipe through a plurality of connecting belts.

[0010] In the line maintenance seat as described above, a first buckle is fixedly disposed at one end of the safety belt, and a second buckle is fixedly disposed at the other end of the safety belt, and the first buckle can be engaged with the second buckle.

[0011] The advantages of the utility model are: the utility model has a simple structure and an ingenious design. When the staff climbs to the maintenance height, the staff only needs to sit on the vertical pole without removing the feet from the foot buckles, thereby avoiding the problem that the staff cannot get down from the pole due to the foot buckles falling off the pole; at the same time, it also avoids the risk of falling caused by the staff removing the feet from the foot buckles, can meet market demand, and is suitable for promotion. When using the present invention, when the worker climbs to the maintenance height, the outer periphery of the upper horizontal tube is pressed against the electric pole, so that the two legs of the worker are respectively located on the left and right sides of the vertical pole, and then the U-shaped rod is pulled to move the U-shaped rod to the left, and the movement of the U-shaped rod to the left drives the first horizontal rod and the second horizontal rod to move to the left. At this time, the sliders slide to the left along the corresponding slide grooves respectively, until the sliders slide into the annular grooves respectively, and at this time, the second horizontal rod is completely located outside the lower horizontal tube, and then the U-shaped rod is rotated along the axis of the first horizontal rod, and the rotation of the U-shaped rod drives the first horizontal rod and the second horizontal rod to rotate, and at this time, the sliders slide along the annular grooves respectively, until the slider, the U-shaped rod, the first horizontal rod and the second horizontal rod are respectively rotated. One hundred and eighty degrees, and then push the U-shaped rod to the right. The U-shaped rod moves to the right, driving the first cross bar and the second cross bar to move to the right and reset. The sliders slide out of the annular groove and slide into the corresponding slide grooves respectively. Since the distance between the upper cross tube and the second cross bar is greater than the diameter of the utility pole, the second cross bar does not contact the outer periphery of the utility pole at this time. Then continue to rotate the U-shaped rod, and the rotation of the U-shaped rod drives the second cross bar to rotate until the outer periphery of the second cross bar contacts the outer periphery of the utility pole. At this time, the utility pole is stuck between the upper cross tube and the second cross bar, and the staff sits on the vertical pole. Due to the pressure of the staff on the maintenance seat, the friction between the maintenance seat and the utility pole can ensure that the maintenance seat will not fall.

[0016] A line maintenance stand, such as Figure 1 , 2, 3, and 4, comprising a transverse tube 1, the number of which is two, the two transverse tubes 1 being distributed up and down and one end of each transverse tube 1 being closed, the two transverse tubes 1 being fixedly connected by a vertical rod 3, the two ends of each vertical rod 3 being fixedly connected to the outer periphery of each corresponding transverse tube 1, the two transverse tubes 1 and the vertical rod 3 together forming an "I" character, characterized in that a first transverse rod 4 is movably provided in the upper transverse tube 1, the first transverse rod 4 being coaxially arranged with the upper transverse tube 1, a plurality of sliders 5 being fixedly installed on the first transverse rod 4, the outer periphery of the first transverse rod 4 being fixedly connected to one side of the slider 5, In the embodiment, there are two sliders 5, which are symmetrically distributed up and down. A slide groove 6 is provided on the inner wall of the upper transverse tube 1 corresponding to the slider 5. The sliders 5 are slidably installed in the corresponding slide grooves 6. An annular groove 7 is provided on the inner wall of the upper transverse tube 1. The annular groove 7 is located at the open end of the upper transverse tube 1. The annular groove 7 is communicated with the slide groove 6. The sliders 5 can slide into the annular groove 7 respectively. A second cross bar 8 is movably provided in the lower transverse tube 1. The second cross bar 8 is coaxially arranged with the lower transverse tube 1. The length of the second cross bar 8 is less than the length of the first cross bar 4. Figure 2As shown, the distance between the second crossbar 8 and the upper cross tube 1 is greater than the diameter of the electric pole 100, and the first crossbar 4 and the second crossbar 8 are fixedly connected by a U-shaped rod 9, one end of the U-shaped rod 9 is fixedly connected to one end of the first crossbar 4, and the other end of the U-shaped rod 9 is fixedly connected to one end of the second crossbar 8. The utility model has a simple structure and an ingenious design. When the staff climbs to the maintenance height, the staff can sit on the vertical pole without removing the feet from the foot buckle, thereby avoiding the problem that the staff cannot get down from the electric pole due to the foot buckle falling off the electric pole; at the same time, it also avoids the risk of falling caused by the staff removing the feet from the foot buckle, which can meet market demand and is suitable for promotion. When using the present invention, when the worker climbs to the maintenance height, the outer periphery of the upper horizontal tube 1 is pressed against the electric pole 100, so that the two legs of the worker are respectively located on the left and right sides of the vertical rod 3, and then the U-shaped rod 9 is pulled to move the U-shaped rod 9 to the left, and the movement of the U-shaped rod 9 to the left drives the first cross bar 4 and the second cross bar 8 to move to the left. At this time, the sliders 5 slide to the left along the corresponding slide grooves 6 respectively, until the sliders 5 slide into the annular grooves 7 respectively, at which point the second cross bar 8 is completely located outside the lower horizontal tube 1, and then the U-shaped rod 9 is rotated along the axis of the first cross bar 4, and the rotation of the U-shaped rod 9 drives the first cross bar 4 and the second cross bar 8 to rotate, at this time, the sliders 5 slide along the annular grooves 7 respectively, until the sliders 5, the U-shaped rod 9, the first cross bar 4 and the second cross bar 8 rotate one hundred and eighty times. Ten degrees, and then push the U-shaped rod 9 to the right. The U-shaped rod 9 moves to the right, driving the first cross bar 4 and the second cross bar 8 to move to the right and reset. The slider 5 slides out of the annular groove 7 and slides into the corresponding slide groove 6 respectively. Since the distance between the upper cross tube 1 and the second cross bar 8 is greater than the diameter of the utility pole 100, the second cross bar 8 does not contact the outer periphery of the utility pole 100 at this time. Then continue to rotate the U-shaped rod 9. The rotation of the U-shaped rod 9 drives the second cross bar 8 to rotate until the outer periphery of the second cross bar 8 contacts the outer periphery of the utility pole 100. At this time, the utility pole 100 is stuck between the upper cross tube 1 and the second cross bar 8, and the staff sits on the vertical rod 3. Due to the pressure of the staff on the maintenance seat, the friction between the maintenance seat and the utility pole 100 can ensure that the maintenance seat will not fall.

[0017] Specifically, as shown in the figure, in this embodiment, the first cross bar 4 is connected to the corresponding cross tube 1 through a spring 20, and a groove 21 is formed at one end of the first cross bar 4 away from the U-shaped bar 9, and the spring 20 is located in the groove 21, and one end of the spring 20 is fixedly connected to the inner wall of the groove 21, and the other end of the spring 20 is fixedly connected to the inner wall of the corresponding cross tube 1. Pulling the first cross bar 4 moves the first cross bar 4 to the left, and the spring 20 stretches; releasing the first cross bar 4, and under the elastic force of the spring 20 itself, the first cross bar 4 is reset.

[0018] Specifically, as shown in the figure, two arc blocks 30 are fixedly installed on the outer periphery of the upper cross tube 1 in this embodiment, and an arc groove 31 is provided on the outer periphery of the second cross bar 8. Figure 2 As shown, the arc block 30 and the arc groove 31 are coaxially arranged with the electric pole 100. Through the arc block 30 and the arc groove 31, the upper cross tube 1 and the second cross bar 8 are convenient to fit with the electric pole 100.

[0019] Further, as shown in the figure, the arc block 30 and the arc groove 31 of this embodiment are respectively fixed with an anti-skid rubber layer 40. The anti-skid rubber layer 40 can increase the friction between the cross tube 1 and the second cross bar 8 and the electric pole 100, thereby preventing the maintenance seat from sliding off the electric pole 100.

[0020] Further, as shown in the figure, a safety belt 50 is provided on one side of the vertical pole 3 in this embodiment, and the safety belt 50 is fixedly connected to the horizontal tube 1 through a plurality of connecting straps 51. In this embodiment, there are two connecting straps 51, one end of each connecting strap 51 is fixedly connected to one side of the safety belt 50, and the other end of each connecting strap 51 is fixedly connected to the outer periphery of the corresponding horizontal tube 1. Tying the safety belt 50 around the waist can increase the safety of the staff when working on the electric pole 100.

[0021] Furthermore, as shown in the figure, one end of the safety belt 50 of this embodiment is fixedly provided with a first buckle 60, and the other end of the safety belt 50 is fixedly provided with a second buckle 61, and the first buckle 60 can be engaged with the second buckle 61. The first buckle 60 and the second buckle 61 make it easier to tie the safety belt 50 around the waist or take it off at the waist; by pressing both sides of the first buckle 60 at the same time, and then pulling the second buckle 61, so that the second buckle 61 moves in a direction away from the first buckle 60, the first buckle 60 can be separated from the second buckle 61, so that the safety belt 50 can be taken off at the waist; similarly, the safety belt 50 is made to surround the waist, and the left and right sides of the first buckle 60 are pressed at the same time, and then the second buckle 61 is pulled, so that the second buckle 61 moves in a direction close to the first buckle 60, and the first bayonet 60 and the second buckle 61 are plugged and matched, and at this time, the safety belt 50 can be firmly tied around the waist of the staff.
