Description

Technical Field

[0001] The utility model belongs to the technical field of deicing tools, and in particular relates to a contact network deicing tool. Background Art

[0002] Currently, traction power systems are widely used as train power supply systems in rail transit systems such as railways and subways, with contact-type overhead power lines being the primary application. Due to their nature, contact-type overhead power lines are often installed outdoors, making them less resilient to extreme weather events. Liquid rain quickly freezes on the contact wires, forming an ice shell that clings tightly to the metal and is difficult to remove. This can lead to undervoltage and power loss in the train, damaging the pantograph. In severe cases, the entire overhead line can be crushed, causing widespread network collapse. Freezing rain disasters are currently more frequent in southern my country, but also occur sporadically in northern China. However, specialized de-icing tools are currently lacking.

[0003] The existing de-icing process requires workers to manually break the ice on the contact line when the vehicle is not in operation, which is time-consuming and labor-intensive. At the same time, in winter, workers standing at a height to knock on the contact line may easily slip and fall from a height, which is unsafe. Summary of the Invention

[0004] The utility model provides a contact network de-icing tool, the purpose of which is to solve the problem that in the existing de-icing work, workers are required to manually break the ice layer on the contact network when the vehicle is not working, which is time-consuming and labor-intensive. At the same time, in winter, workers standing at a high place to knock on the contact line are prone to slipping and falling from a high place, which is unsafe.

[0005] An embodiment of the utility model provides a contact network de-icing tool, including a support rod, handles fixedly connected to both sides of the support rod, a placement frame fixedly connected to the top of the support rod, a vibration device installed in the placement frame, a closing mechanism is provided in the placement frame and the support rod, and a locking mechanism is provided at the bottom of the support rod between the handles.

[0006] Furthermore, a notch is reserved on the placement frame, and sliding grooves are provided at both ends of the notch.

[0007] By adopting the above technical solution, the cables to be crushed ice can enter the inner peripheral side of the placement frame through the notch.

[0008] Furthermore, the vibration device is installed on the inner circumference of the placement frame.

[0009] By adopting the above technical solution, the vibration device on the inner circumference of the placement frame makes it easy for users to vibrate and break ice on the cables therein, saving time and effort.

[0010] Furthermore, the closing mechanism includes a rotating rod rotatably connected to the support rod and a tooth groove slidably connected to the sliding groove, the bottom of the rotating rod extends to the outside of the support rod and is fixedly connected to a rotating handle, the top of the rotating rod extends to the placement frame, the top of the rotating rod is a snail-shaped surface, and engages with the tooth groove.

[0011] By adopting the above technical solution, the rotating handle is rotated to drive the rotating rod to rotate, and the spiral surface at the top of the rotating rod also rotates synchronously, so that the tooth groove can slide in the sliding groove under the drive of the spiral surface at the top of the rotating rod, thereby closing the gap of the placement frame and preventing the cable from slipping out of the gap during the ice crushing process.

[0012] Furthermore, the locking mechanism includes sockets reserved on both sides of the bottom of the support rod and through holes running through both sides of the rotating handle. The bottom of the rotating handle is provided with a threaded hole extending toward the support rod, and the threaded hole is connected to the through hole. The upper ends of the first fixing part and the second fixing part are respectively inserted into the sockets on both sides, and the lower ends of the first fixing part and the second fixing part are located at the intersection in the through hole and fixed by bolts.

[0013] By adopting the above technical solution, after the gap is closed, the upper ends of the first fixing part and the second fixing part are respectively inserted into the insertion holes on both sides, and the lower ends of the first fixing part and the second fixing part are inserted into the through hole. At the same time, the first fixing part and the second fixing part are fixed by bolts, so that the rotating handle can no longer be rotated, thereby achieving a locking effect on the rotating rod, avoiding the vibration of the vibration device during the de-icing process, which causes the closing mechanism to loosen, and then the rack slides, causing the cable to slip out of the gap.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model provides a placement frame and a vibration device, so that the cable to be crushed ice can enter the inner circumference of the placement frame through the gap. The vibration device on the inner circumference of the placement frame facilitates the user to vibrate and crush the ice on the cable, saving time and effort.

[0016] 2. The utility model sets a closing mechanism. By rotating the rotating handle, the rotating rod is driven to rotate. The spiral surface at the top of the rotating rod also rotates synchronously, so that the tooth groove can slide in the sliding groove under the drive of the spiral surface at the top of the rotating rod, thereby closing the gap of the placement frame and preventing the cable from slipping out of the gap during the ice crushing process.

[0017] 3. The utility model provides a locking mechanism. After the gap is closed, the upper ends of the first fixing part and the second fixing part are respectively inserted into the insertion holes on both sides, and the lower ends of the first fixing part and the second fixing part are inserted into the through hole. At the same time, the first fixing part and the second fixing part are fixed by bolts, so that the rotating handle can no longer be rotated, thereby achieving a locking effect on the rotating rod, avoiding the vibration of the vibration device during the de-icing process, which may cause the closing mechanism to loosen, and then the rack to slide, causing the cable to slip out of the gap.
