Description

Technical Field

[0001] The utility model relates to the technical field of high-speed railway contact network equipment, in particular to a high-speed railway contact network pillar. Background Art

[0002] The high-speed railway contact network is an electric power network equipment used to continuously provide electric energy to the moving high-speed trains. During the travel of the high-speed train, the contact bow on the top of the train will always come into contact with the cables on the contact network to obtain electric energy.

[0003] The high-speed railway contact network includes pillars arranged equidistantly on both sides of the railway, which are used to support various contact network components and cables. Whether the high-speed train can run normally and safely depends entirely on whether the contact network equipment can work normally. Therefore, the high-speed railway contact network equipment needs to be regularly inspected and maintained. During the inspection and maintenance process, the staff needs to climb to the top of the pillars to inspect the various components installed on the pillars. Since the pillars are high, the staff needs to climb to the top of the pillars with the assistance of a lifting device during the inspection and maintenance. The lifting device needs to move with the maintenance staff throughout the entire inspection and maintenance work, which makes the inspection and maintenance work more troublesome and increases the cost of the inspection and maintenance work.

[0004] The Chinese invention patent with patent application number CN202310886537.1 records an ultra-high performance concrete transverse rod-type support for electrified railway contact network, which provides a foothold for workers to climb the support by setting up a stepped distributed web and a climbing plate connected to the web by a spring, so that the workers can climb to the top of the support by themselves without relying on a lifting device, thereby reducing the cost of maintenance work and simplifying the maintenance work. However, the climbing plate in the above-mentioned support is a flat plate, which may cause the workers' feet to slip off the climbing board from the side when they step on the climbing board, thereby posing a hidden danger to the safety of the workers. Utility Model Content

[0005] The purpose of the present application is to provide a high-speed railway contact network pillar to solve the problem mentioned in the above background technology that when workers step on the climbing board, there is a possibility that their feet may slip off the climbing board from the side, thereby posing a hidden danger to the safety of the workers.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a high-speed railway contact network pillar, comprising a fixed seat, the top of which is fixedly connected to an H-steel column, two groups of transverse ribs are symmetrically fixedly connected to the front and rear sides of the column, and each group of multiple transverse ribs are equidistantly distributed from top to bottom, and a climbing assembly is provided on the transverse rib plate, the climbing assembly comprises two side baffles fixedly connected to the top of the transverse rib plate, the climbing assembly also comprises a pedal connected to the top of the transverse rib plate, the pedal is located in the middle of the two side baffles, the two side baffles are distributed in an eight-shaped shape, and the climbing assemblies on the two adjacent transverse rib plates are staggered.

[0007] Preferably, the climbing assembly also includes two groups of elastic telescopic rods symmetrically fixedly connected to the top of the cross rib plate, the two groups of elastic telescopic rods are located between the two side baffles, and the bottom of the pedal is fixedly connected between the tops of the two groups of elastic telescopic rods, and the climbing assembly also includes two rotating shafts symmetrically fixedly connected to the side surfaces of the column, and two limit plates are symmetrically rotatably sleeved on the outer circumferential surfaces of the two rotating shafts, and a first torsion spring is fixedly connected between the side surfaces of the limit plates and the column close to each other, and the side surfaces of the two limit plates close to each other respectively abut against the left and right side surfaces of the pedal, and two first through cavities are symmetrically provided on the side surfaces of the two side baffles. The advantage of such an arrangement is that, through the elastic telescopic rod, when the staff member steps on the pedal, the pedal will move downward, so that the two limit plates rotate under the elastic force of the first torsion spring and the tops of the two limit plates are close to each other, so that the staff member's feet can be more effectively limited to the left and right, thereby effectively preventing the staff from slipping when stepping on the pedal, thereby improving the maintenance safety of the pillar.

[0008] Preferably, it also includes a fastening component arranged on the transverse rib plate for limiting the rotation of the limit plate, the fastening component includes two groups of elastic members symmetrically fixedly connected to the top of the transverse rib plate, the tops of the two groups of elastic members are fixedly connected to pressure plates, the top of the pressure plate conflicts with the bottom of the pedal, the left and right sides of the pressure plate are symmetrically connected to two top plates for rotation through a rotating rod and a second torsion spring, two groups of sliding cavities are symmetrically opened on the side surfaces of the two top plates, the number of sliding cavities in each group is two, and two second through cavities are symmetrically opened on the side surfaces of the two limit plates, the fastening component also includes two cross bars symmetrically fixedly connected to the top of the transverse rib plate, the two ends of the two cross bars respectively pass through the two second through cavities and the two first through cavities, and the two cross bars slide respectively The two sets of sliding cavities are connected, and a gap is left between the bottom end of the top plate and the top of the cross rib plate. The advantage of such a setting is that when the staff steps on the pedal, the pedal overcomes the elastic force of the elastic member and pushes the pressure plate downward, thereby driving the bottom ends of the two top plates to rotate in opposite directions under the limiting action of the two sets of cross bars, so that the two top plates push the two limit plates to rotate. At this time, the bottom ends of the two top plates are tightly against the sides of the two limit plates, thereby preventing the two limit plates from rotating in the opposite direction. In this way, when the staff member rotates his toes to squeeze the limit plate when stepping on the pedal, the limit plate will not rotate in the opposite direction, ensuring that the limit plate can reliably limit and block the feet of the staff, thereby further improving the safety protection effect for the staff.

[0009] Preferably, the distance between the top surface of the limit plate and the top surface of the pedal is not less than thirty centimeters. The advantage of this arrangement is that it can ensure that the tops of the two limit plates are located on the upper side of the staff's instep, preventing the staff's feet from slipping against the pedals, thereby ensuring the safety of the staff's maintenance work.

[0010] In summary, the technical effects and advantages of the utility model are:

[0011] 1. In the utility model, two side baffles are provided to block and limit the left and right sides of the pedal, so that when the toes of the staff rotate or slide sideways when stepping on the pedal, the feet will not slip off the pedal, thereby effectively protecting the working safety of the staff.

[0012] 2. In the utility model, by setting up the fastening assembly, when the staff steps on the pedal, the bottom ends of the two top plates respectively press against the two limit plates, preventing the two limit plates from rotating away from the feet due to being squeezed by the staff's feet, thereby further improving the protection of the staff's working safety.

The climbing assembly 4 also includes two rotating shafts 44 symmetrically fixedly connected to the side of the column 2, and two limit plates 45 are symmetrically rotatably sleeved on the outer circumference of the two rotating shafts 44.

The fastening assembly 5 includes two groups of elastic members 51 symmetrically fixedly connected to the top of the transverse rib plate 3, and the tops of the two groups of elastic members 51 are fixedly connected to a pressure plate 52, and the top of the pressure plate 52 conflicts with the bottom of the pedal 43. The left and right sides of the pressure plate 52 are symmetrically connected to two top plates 53 for rotation through a rotating rod and a second torsion spring.

[0026] Specifically, when the staff member steps on the pedal 43, the pedal 43 overcomes the elastic force of the elastic member 51 and pushes the pressure plate 52 downward, thereby driving the bottom of the two top plates 53 to rotate in opposite directions under the limiting action of the two sets of cross bars 55, so that the two top plates 53 push the two limiting plates 45 to rotate. At this time, the bottom ends of the two top plates 53 are tightly against the sides of the two limiting plates 45, thereby preventing the two limiting plates 45 from rotating in the opposite direction. In this way, when the staff member rotates his toes to squeeze the limiting plates 45 when stepping on the pedal 43, the limiting plates 45 will not rotate in the opposite direction, thereby ensuring that the limiting plates 45 can reliably limit and block the feet of the staff member, thereby further improving the safety protection effect for the staff member.
