Abstract
Description
Technical Field
[0001] The invention relates to an insulating horizontal ladder, in particular to a suspension bridge type insulating horizontal ladder. Background Art
[0002] With the development of the economy and society, various types of electricity users have higher and higher requirements for the continuous supply of electricity. On the other hand, the various hidden dangers and risks faced by transmission lines are also increasing exponentially, especially in special weather conditions such as flood season. Using an insulating repair tower to erect a transmission line tower collapse accident caused by natural disasters is a fast and effective way to restore power supply. After the insulating repair tower is erected and supports the conductor, the operator enters the conductor and uses a horizontal soft ladder to install the relevant hardware using the equipotential operation method. During the use of the existing horizontal ladder, the operator needs to carry an insulating transfer rope for high-altitude transmission. This method has the following disadvantages: First, the operator needs to carry the insulating transfer rope when climbing the tower, which poses a great safety hazard; second, when using the transfer rope for transmission, more operators need to participate, which brings certain difficulties to the operation organizers; third, when the horizontal ladder reaches the designated position of the insulating repair tower, it needs to be manually tied, and the operation time is long. Summary of the invention
[0003] In order to solve the above problems, the present invention provides a suspension bridge type insulating horizontal ladder used on an insulating emergency repair tower.
[0004] The technical solution of the present invention is: a suspension bridge type insulating horizontal ladder, comprising: a horizontal ladder body and a rotating fixed body installed on a repair tower;
[0005] The rotating fixed body includes an upper horizontal plate and a lower horizontal plate, two fixing columns are arranged between the upper horizontal plate and the lower horizontal plate, and the left and right sides of the upper horizontal plate and the lower horizontal plate are both provided with fixing parts fixed on the vertical beam of the emergency repair tower;
[0006] The horizontal ladder body includes a first vertical rod, a second vertical rod and a plurality of cross rods arranged between the first vertical rod and the second vertical rod; one end of the cross rod is fixedly connected to the first vertical rod, and the other end is slidably connected to the second vertical rod; the bottom ends of the first vertical rod and the second vertical rod are fixedly connected to chain clamps that can be tied to the fixed column, and both end ends of the chain clamp are provided with fastening blocks, and fastening holes are provided on the fastening blocks.
[0007] Furthermore, a plurality of slide grooves are arranged on the second vertical rod, and a sliding block adapted to the slide grooves is arranged on one end of the cross rod connected to the second vertical rod.
[0008] Furthermore, the chain hoop comprises an upper chain plate and a lower chain plate, and a plurality of elastic rollers are arranged between the upper chain plate and the lower chain plate.
[0009] Furthermore, a T-shaped limit block is provided on one side of the elastic roller close to the fixed column;
[0010] The fixed column includes an upper column and a lower column. One side of the upper column and the lower column is hinged. The sides of the upper column and the lower column that are close to each other are both provided with limiting grooves. A T-shaped limiting space adapted to the T-shaped limiting block is formed between the upper column and the lower column.
[0011] Furthermore, two reinforcing ribs which are detachably connected to the vertical beams of the emergency repair tower are arranged on the lower horizontal plate.
[0012] Furthermore, pull ropes are provided on both the first vertical rod and the second vertical rod.
[0013] Furthermore, anti-slip grooves are provided on the crossbar.
[0014] The suspension bridge type insulating horizontal ladder provided by the present invention first fixes the rotating fixed body at the appropriate position of the emergency repair tower before the emergency repair tower is erected, and then fixes the horizontal ladder body to the fixed column of the fixed body through a chain clamp, and also fixes the insulating rope to the appropriate position of the emergency repair tower and the horizontal ladder body. During the erection of the emergency repair tower, the horizontal ladder is driven to stand up. When in use, the high-altitude operator only needs to loosen one end of the horizontal ladder tied with the insulating rope, and rely on the insulating rope to operate the horizontal ladder to overlap the wire. In addition, because the horizontal ladder body is fixed to the fixed column of the fixed body through a chain clamp, the horizontal ladder can be rotated within a certain range, which is convenient for repairing different phase lines and easy to use. The present invention avoids the operating link that the operator needs to carry the insulating transfer rope when climbing the pole tower, greatly improving the safety benefit; reducing the number of personnel involved in the operation, reducing the difficulty of organizing the operation; when the suspension bridge type insulating horizontal ladder is used, only one operator is required to operate, eliminating the process of ground operators transferring the horizontal ladder, greatly saving operation time, and improving operation efficiency; the horizontal ladder can be rotated, which is convenient for repairing different phase lines.

It should be noted that the upper horizontal plate 7 and the lower horizontal plate 10 can be fixed to the vertical beam of the emergency repair tower by bolts through the fixing part 8, which is convenient for installation.
[0026] The horizontal ladder body includes a first vertical rod 1, a second vertical rod 5, and a plurality of cross rods 2 arranged between the first vertical rod 1 and the second vertical rod 5; one end of the cross rod 2 is fixedly connected to the first vertical rod 1, and the other end is slidably connected to the second vertical rod 5; the bottom ends of the first vertical rod 1 and the second vertical rod 5 are fixedly connected with a chain clamp 3 that can be tied to the fixed column 9. For the convenience of use, the horizontal ladder is fixed on the chain clamp 3 in an inclined state. Both ends of the chain clamp 3 are provided with fastening blocks 4, and the fastening blocks 4 are provided with fastening holes 6. When in use, bolts are used to pass through the fastening holes 6 to tighten the chain clamp 3, thereby fixing the horizontal ladder body. Because the horizontal ladder is fixed to the fixed column 9 through the chain clamp 3, and one end of the cross rod 2 is movable, the horizontal ladder can rotate within a certain range.

At the same time, a T-shaped limit block 13 is arranged on the side of the elastic roller 12 close to the fixed column 9; the fixed column 9 includes an upper column 901 and a lower column 902, one side of the upper column 901 and the lower column 902 are hinged, and the side close to the upper column 901 and the lower column 902 are both provided with a limit groove; a T-shaped limit space adapted to the T-shaped limit block 13 is formed between the upper column 901 and the lower column 902.
[0031] During installation, first fix the upper horizontal plate 7 of the rotating fixed body to the vertical beam of the emergency repair tower, then insert the T-shaped limit block 13 of the chain clamp 3 into the limit groove of the upper column 901, then buckle the lower column 902 and fix it to the vertical beam of the emergency repair tower, lock the chain clamp 3, and finally fix the reinforcing rib 11 to the vertical beam of the emergency repair tower.
[0032] The aerial workers push the horizontal ladder hard to make it rotate around the fixed column 9. The chain clamp 3 is provided with a T-shaped limit block 13, which can realize the limit effect on the one hand and further improve the stability of the horizontal ladder on the other hand.
[0033] The above disclosure is only a preferred embodiment of the present invention, but the present invention is not limited thereto. Any non-creative changes that can be thought of by a person skilled in the art, as well as several improvements and modifications made without departing from the principle of the present invention, should fall within the protection scope of the present invention.
