Description

Technical Field

[0001] This utility model relates to an anti-icing device for rigid sliding contact lines used in outdoor walking equipment, belonging to the field of conductive connection technology. Background Technology

[0002] Most steel enterprises in northern my country experience prolonged periods of low temperatures during winter production, with temperatures dropping as low as -30°C. Affected by freezing rain, snow, and frost, outdoor traveling equipment using rigid conductor rails as the conductive carrier frequently experiences power outages and struggles to operate stably. The main reason is that rain and snow freeze on the surface of the rigid conductor rail, causing poor contact between the contactor and the rail, resulting in power interruptions. Manually spraying antifreeze onto the rigid conductor rail is not only inefficient but also poses a risk of electric shock to personnel. If a conduit is fixed to the contactor for dripping, vehicle vibration and deformation of the rigid conductor rail make it difficult to accurately and quantitatively add antifreeze; adding too little is ineffective, while adding too much causes environmental pollution and fire hazards. Therefore, it is essential to design a device that can accurately and quantitatively add antifreeze to rigid conductor rails. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a rigid sliding contact line anti-icing device to improve antifreeze spraying efficiency, eliminate safety hazards, and ensure the personal safety of workers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An anti-icing device for a rigid conductor rail includes a support column, a positioner, an elastic connecting arm, and a liquid filling device. The support column is fixed to the vehicle body of the traveling equipment. The positioner is slidably mounted on the upper part of the rigid conductor rail. The elastic connecting arm connects the support column and the positioner, and the elastic force of the elastic connecting arm presses the positioner onto the rigid conductor rail. The liquid filling device includes a storage tank, a filling pipe, and a flow regulator. The storage tank is mounted on the top of the support column. One end of the filling pipe is connected to the storage tank, and the other end extends along the elastic connecting arm and the positioner to the upper surface of the rigid conductor rail. The flow regulator is mounted on the filling pipe.

[0006] The aforementioned rigid sliding contact line anti-icing device comprises an elastic connecting arm including a front connecting frame, a rear connecting frame, an upper cross arm, a lower cross arm, a tension spring, a connecting arm pivot, a base, and an insulator. The front part of the front connecting frame is rotatably connected to the top of the locator. The insulator is fixedly connected to the side wall of the support column via its rear steel foot. The base is fixedly connected to the metal attachment at the front end of the insulator. The rear connecting frame is rotatably connected to the base via a vertical connecting arm pivot.

One end of the tension spring is connected to the middle of the upper cross arm, and the other end is connected to the rear end of the lower cross arm.

[0007] The aforementioned anti-icing device for rigid conductor rails includes a positioning frame, six positioning rollers, and a positioning shaft. The positioning frame is located above the rigid conductor rail and is rotatably connected to the front connecting frame via the positioning shaft. The six positioning rollers are divided into three groups and installed on the positioning frame. One group of positioning rollers is in rolling connection with the upper surface of the rigid conductor rail, and the other two groups of positioning rollers are in rolling connection with the two side walls of the rigid conductor rail, respectively.

[0008] The aforementioned rigid sliding contact line anti-icing device includes a locator shaft comprising a shaft tube, a shaft top cover, two shaft cups, multiple shaft balls, and two ball holders. The locator has a vertical hole in the middle, and the two ball holders are fitted into the two ends of the vertical hole. Each ball holder contains a shaft ball. The shaft tube passes through the vertical hole in the middle of the locator and the central hole of the two ball holders. The two shaft cups are respectively fastened to the two ball holders and are threadedly connected to both ends of the shaft tube. The upper end of the shaft tube passes through the vertical through hole on the front connecting frame and is threadedly connected to the shaft top cover. The liquid filling tube passes through the central hole of the shaft tube and extends to the upper surface of the rigid sliding contact line.

[0009] In the aforementioned rigid sliding contact line anti-icing device, the liquid storage tank is installed on the top of the support column via a liquid storage tank bracket. The liquid storage tank bracket includes a bracket base plate and a restraint frame. The bracket base plate is fixed to the top of the support column. The restraint frame includes two strip steel coiled into rings and a vertical steel strip. The joints of the two strip steel are welded to the upper end and the middle of the vertical steel strip, respectively. The lower end of the vertical steel strip is welded to the side of the bracket base plate. The liquid storage tank is placed on the bracket base plate and surrounded by the two strip steel.

[0010] In the aforementioned rigid sliding contact line anti-icing device, the liquid storage tank is made of PVC, the liquid filling pipe is made of PE, and the flow regulator is an infusion flow regulator.

[0011] The aforementioned rigid sliding contact line anti-icing device has a fixing ring on both the front connecting frame and the upper cross arm that matches the liquid filling pipe.

[0012] In the aforementioned rigid sliding contact line anti-icing device, the flow regulator is located on the side of the insulator closest to the liquid storage tank.

[0013] This invention utilizes an elastic connecting arm and a positioner to guide the filling pipe of the filling device to the upper surface of the rigid sliding contact line. At the same time, it uses a flow regulator to precisely control the flow rate of antifreeze. This not only ensures the anti-icing effect and avoids the waste of antifreeze, but also improves the antifreeze spraying efficiency, eliminates safety hazards, and ensures the personal safety of workers.

Holes are drilled in the center of the two channel walls of the channel steel. A set of bolts serves as the connecting arm pivot 24. The bushing of the rear connecting frame 10 is located between the two channel walls of the channel steel. The connecting arm pivot 24 passes through the center holes of the two channel walls and the bushing of the rear connecting frame 10, so that the rear connecting frame 10 is rotatably connected to the base 25. Holes are drilled at both ends of the center line of the web of the channel steel and are bolted to the metal fittings 27 of the insulator 4. The steel feet 28 of the insulator 4 are bolted to the side wall of the support column 1.

[0030] An embodiment of this utility model is as follows:

[0031] Support column 1 is made of #8 channel steel, 1500mm long;

[0032] Insulator 4 adopts JGH type rigid sliding contact line epoxy resin insulator;

[0033] Positioning frame 6 is made of 2mm steel plate and 30mm square steel;

[0034] Positioning roller 7 is a set of φ50mm×30mm nylon rollers;

[0035] The front connecting frame 9 is welded from a 70mm long 7# equilateral angle steel and a 50mm×30mm×2mm steel plate;

[0036] The rear connecting frame 10 is welded from a 50mm long four-point welded pipe and a 50mm×30mm×2mm steel plate;

[0038] The tension spring 13 is model C-WAWT8-80;

[0039] The positioner shaft 8 uses a ball bearing cup assembly with a diameter of 15mm and a length of 40mm;

[0040] The base 25 is made of 6.3# channel steel and is 80mm long;

[0041] Fixed ring 26 is a φ10 solid O-ring;

[0042] The liquid filling tube 30 is a φ10 PVC single-layer transparent flexible tube;

[0043] Flow regulator 31 is an ABS infusion flow regulator;

[0044] Storage tank 32 is a 15L PVC storage tank;

[0045] The support base plate 33 is made of 200mm×200mm×4mm steel plate;

[0046] The restraint frame 34 is made of 10mm steel strip;

[0047] The rigid conductor rail 35 is a JGH-I type rigid conductor rail.

[0048] The usage process of this utility model is as follows (taking the usage process of a coking quenching car as an example):

[0049] Antifreeze is only added before or at the beginning of cold, rainy or snowy weather to prevent rain and snow from freezing on the surface of the rigid contact wire and affecting power supply. The antifreeze filling process is a specialized task, not something that is done while production is underway.

[0050] First, park the vehicle in the eastern maintenance section and de-energize the eastern maintenance power supply of the rigid contact line. Because antifreeze is conductive, a power outage is necessary for safety during the installation process. Move the flow regulator 31 to the side of the insulator 4 closest to the reservoir 32, close the flow regulator, and add antifreeze to the reservoir. If you are new to adding antifreeze and have no experience adjusting the flow rate, you can pull out the filling tube from the positioner shaft 8, insert it into an empty water bottle, and align the filling tube with the top of the rigid contact line. Adjust the flow rate of each branch pipe to 5ml / s-10ml / s. After adjusting the flow rate, insert the filling tube back into the positioner shaft 8. Re-energize the eastern maintenance power supply of the rigid contact line. Start the vehicle and travel at a constant speed of 10Hz (approximately 0.5m / s) westwards along the entire length, ensuring the antifreeze is evenly applied to the conductive contact surface of the rigid contact line. Once you reach the western maintenance section, close the flow regulator; the filling process is now complete. Because of PVC insulation, the flow rate can be manually adjusted or shut off during rigid conductor rail power supply. Based on experience, the flow rate should be adjusted appropriately during refilling according to site conditions, influenced by factors such as temperature, viscosity of different brands of antifreeze, and size of the rigid conductor rail. The minimum refill amount should be sufficient to prevent any breaks in the rigid conductor rail, and the maximum should be sufficient to prevent antifreeze dripping. If the temperature is too low or the rain / snow duration is prolonged, maintenance personnel can increase the refilling frequency and amount as needed.
