DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the specification.

[0023] like Figure 1 and Figure 2As shown, the utility model relates to a feeding pantograph, which comprises a lifting bow 1, a vertical pole 2, a spring strut 3 and a tension spring 4. The lifting bow 1 and the vertical pole 2 are both straight rod structures, and the two are connected in a "T" shape. The spring strut 3 and the tension spring 4 are arranged on opposite sides of the middle section of the vertical pole 2 and extend radially toward the lifting bow 1. The extended ends of the two are connected to the lifting bow 1 to form a triangular support structure respectively. The vertical pole 2 comprises a rod body 21 and a connecting shaft 22 installed at the top of the rod body 21. The middle section of the lifting bow 1 is rotatably connected to the connecting shaft 22 to form a triangle support structure with the top of the rod body 21. The spring support rod 3 is a "T"-shaped lever structure with a fulcrum, and is composed of a guide sleeve 31 and a compression spring 32. The guide sleeve 31 is a multi-section and retractable sleeve structure. The two ends of the guide sleeve 31 are respectively connected to the lifting bow 1 and the rod body 21. The compression spring 32 is sleeved on the outer periphery of the guide sleeve 31, and the two ends are fixedly connected to the guide sleeve 31, forming a damping rod mechanism in which the extension or contraction of the guide sleeve 31 is both under the external force of the compression spring 32. The lifting bow 1 has an extended end with a length exceeding the connection with the guide sleeve 31, and the end has a mounting position for installing a feeding device. The lifting bow 1 is used to support the feeding device and work at the set cable height. The end of the vertical pole 2 is connected to the 1 / 3 position of the lifting bow 1 to form a "T" shape, and the lever structure with the connection position of the connecting shaft 22 as the fulcrum. The lifting bow 1 can be divided into two sections from the connection position, namely a long section and a short section. The end of the long section is used to install the feeding device. A spring strut 3 and a tension spring 4 are respectively arranged on both sides of the "T"-shaped structure. Specifically, the spring strut 3 is installed on one side where the feeding device is set, and the connection position with the lifting bow 1 is located in the middle of the long section, that is, 1 / 3 of the entire lifting bow 1. The tension spring 4 is arranged on the opposite side, and the end is directly connected to the end of the lifting bow 1. In this state, the tension spring 4 provides tension, and the spring strut 3 on the other side provides support force, which work together to provide force to hold the cable for the end of the feeding device.

[0024] During use, the feeder pantograph of the utility model reaches the feeding height. Because the cable usually sags in the middle due to gravity, and the degree of sag will change with the change of temperature, so the working height of the feeder pantograph will be the high point where the cable is erected as the working height. When the device is working, it moves to the position where the cable falls and the feeder device is pressed down by the weight of the cable. First, the end of the lifting bow 1 is pulled by the tension spring 4, and after passing through the drooping section of the cable, the stretched tension spring 4 is restored to pull the feeder device at the other end back. Secondly, the spring support rod 3 on the side where the feeder device is installed is After being pressed down, the spring strut 3 can support the end of the lifting bow 1 through its compression deformation. Specifically, the guide sleeve 31 can change its length when receiving external force, and the compression spring 32 can be compressed under force and can also restore its initial state. The compression spring 32 is prone to bending under pressure. Being mounted on the guide sleeve 31 can avoid the bending problem and will not affect the stress deformation of the compression spring 32. Through the coordinated effect of the spring strut 3 and the tension spring 4, which support one side and hold the other side, it can ensure that the entire feeding bow can maintain contact with the cable after being raised to the working height, and ensure that the feeding device can maintain a working state.

[0025] The feeding pantograph of the utility model can not only be installed with a feeding device, but also with a de-icing device for use, specifically, the equipment installed at the end mounting position, because the weight of the cable increases after being frozen, the middle section will produce a greater amount of droop, and the fitting effect of the device on the cable can provide a better de-icing working environment for the de-icing device.

[0026] The bottom end of the rod body 21 is provided with a base shaft 23 extending along the length direction of its central axis. The base shaft 23 is a cylindrical structure and is coaxially arranged with the rod body 21. The base shaft 23 can rotate at the installation position, so that the entire pantograph can rotate adaptively with the offset between the cable and the track.

[0027] A connecting piece 5 is provided at the connecting position between the guide sleeve 31 and the lifting bow 1 and the rod body 21. The connecting piece 5 includes a clamping ring 51 and a connecting portion 52. The clamping ring 51 is arranged and tightened on the lifting bow 1 and the rod body 21. The connecting portion 52 is fixedly connected to the clamping ring 51 and is arranged on both sides of the lifting bow 1 and the rod body 21 to form an ear-hanging structure. The end of the guide sleeve 31 is fixedly connected to the connecting portion 52; specifically, the number of spring struts 3 and tension springs 4 is 2, and the spring struts 3 and tension springs 4 are respectively arranged in parallel, and the ends are connected to the connecting portion 52 on the connecting piece 5. By setting the connecting piece 5, the fixed position can be moved by the clamping ring 51 of the connecting piece 5, and the connecting position of the spring strut 3 and the tension spring 4 can be changed for easy adjustment. The connection portion 52 can be provided to install a spring strut 3. The two parallel spring struts 3 and the two parallel tension springs 4 can respectively provide more stable supporting force and tension at the supporting force position and the tensioning position.

By using hinges to connect, the cross brace 63 can always be connected to the front frame 61 or the rear frame 62, and there is no need to completely disassemble. When disassembly is required, only one end needs to be disassembled, and the other end can be folded through the hinge position and stored or transported together with the connected frame. By setting the diagonal brace 64, a rod is set diagonally on the basis of the cross brace 63, and is located on different sides. The inclination direction of the diagonal brace 64 is opposite, and its projection is in an "X" cross shape from the side perspective, ensuring that the structural frame 6 as a whole has sufficient strength to remain stable.

The top end of the sliding rod 67 is rotatably connected to the base rotating shaft 23. The reinforcing beam can further improve the overall stability of the structural frame 6. On the other hand, it can maintain the upright state of the positioning rod 66 and provide a fixed position for the positioning rod 66. The sliding rod 67 is slidably connected to the positioning rod 66 through the clamp ring. The clamp ring does not need to be tightened at the position, but only provides the function of a positioning guide ring sleeve, so that the sliding rod 67 can slide therein. The end of the top of the sliding rod 67 is rotatably connected to the base rotating shaft 23, providing a rotation point for the entire feeding pantograph and linking the feeding pantograph to rise and fall. The connection structure of the entire structural frame 6 is convenient for disassembly, assembly and transportation, and improves the convenience of use of the device.
