Description

Technical Field

[0001] This utility model relates to the field of de-icing equipment, specifically a de-icing device for railway power supply contact networks. Background Technology

[0002] The overhead contact system is a high-voltage power transmission line that runs in a zigzag pattern above the rails in electrified railways, supplying current to the pantograph. It is the main framework of railway electrification engineering, a special type of power transmission line that supplies power to electric locomotives, and consists of several parts: contact suspension, support devices, positioning devices, supports, and foundations.

[0003] Existing railway power supply contact networks are prone to icing in winter. To prevent obstruction of the pantograph's normal current collection, which could lead to insufficient train power or even train stoppage, it is necessary to remove the ice covering the railway power supply contact networks. However, the following problems still exist in the de-icing process of existing railway power supply contact networks:

[0004] The existing railway power supply contact network uses mechanical de-icing and manual knocking de-icing. Mechanical de-icing is easily affected by geographical environmental factors, such as uneven ground, high transportation costs, and inconvenient operation. Manual knocking de-icing, on the other hand, causes arm swaying and can easily lead to arm pain. Prolonged operation will reduce work efficiency. Therefore, it is necessary to develop a railway power supply contact network de-icing device to be used in the field of existing de-icing equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the inconvenience caused by mechanical de-icing and manual knocking de-icing of existing railway power supply contact networks, this utility model proposes a de-icing device for railway power supply contact networks.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a railway power supply contact network de-icing device, including a pole, a horizontal block fixedly mounted on the top of the pole, a connecting block fixedly mounted on the side of the horizontal block, an operating port symmetrically provided through the horizontal block, the operating ports being located on both sides of the connecting block, a guide rod symmetrically fixedly mounted on each operating port, a traction block movably mounted on each of the two guide rods, an mounting plate fixedly mounted on the bottom of each traction block, a movable port provided through the traction block, a guide rod fixedly mounted on each movable port, a sliding block movably mounted on each guide rod, a telescopic spring mounted on each guide rod, the two ends of the telescopic spring being fixedly mounted to the bottom surface of the sliding block and the movable port respectively, a vertical block fixedly mounted on one end of each sliding block, a first blocking rod fixedly mounted on the top of each vertical block, a second blocking rod fixedly mounted on the bottom of each vertical block, and an operating plate fixedly mounted on each second blocking rod.

[0007] The connecting block is symmetrically and movably equipped with movable rods. The top of the two movable rods is fixedly equipped with a top block, and the bottom of the two movable rods is fixedly equipped with an adjusting plate. Each movable rod is equipped with a spring spring, and the two ends of the spring spring are fixedly assembled with the bottom of the top block and the connecting block, respectively.

[0008] The top block is symmetrically fixedly equipped with extension rods, and each extension rod is fixedly equipped with an operating rod at one end. The operating rods are movably assembled with the operating plate, and each operating rod is fixedly equipped with a limit block at one end.

[0009] A handle is fixedly mounted at the bottom of the upright. An operating cavity is provided inside the upright. Traction ports are symmetrically arranged on the upright and are connected to the operating cavity. A transmission screw is movably mounted on the operating cavity. One end of the transmission screw movably passes through the upright and the handle, and a knob is fixedly mounted on the other end of the transmission screw. The knob is located below the handle.

[0010] The transmission screw is threaded with a threaded sleeve block, and a movable block is symmetrically fixedly mounted on the threaded sleeve block. The movable block is movably assembled with the traction port. A fixed plate is fixedly mounted on one end of each movable block, and an adjusting rod is movably mounted on each fixed plate. The other end of the adjusting rod is movably assembled with the mounting plate.

[0011] A traction roller is fixedly mounted on the upright, and a mounting frame is fixedly mounted on the upright. The mounting frame is located between the traction roller and the handle. A shaft is fixedly mounted on the mounting frame, and a pull rod is movably mounted on the shaft. A pull rope is fixedly mounted on the bottom of the adjusting plate. The pull rope is movably mounted to the traction roller, and one end of the pull rope is fixedly mounted to the pull rod.

[0012] The advantages of this utility model are:

[0013] This invention utilizes a knob to rotate a transmission screw on a threaded sleeve, causing a moving block to move on the traction port. Under the action of an adjusting rod, the guide rods on the operating port of the two traction blocks move in opposite directions until the end faces of the two first and two second blocking rods are in contact with each other. The railway power supply contact network is located inside the first and second blocking rods. Pulling the lever pulls the pull rope, which moves on the traction roller, facilitating the pull of the adjusting plate. This causes the movable rod to move on the connecting block, and the top block drives the elastic spring to extend and retract. The top block then moves the operating rod on the extension rod, which in turn moves the second blocking rod on the operating plate. The second blocking rod moves the sliding block on the vertical block on the guide rod, and the extension and retraction spring causes the first and second blocking rods to strike the power supply contact network. This avoids arm swaying caused by striking, reduces workload, and improves work efficiency. Attached Figure Description
