The deformed sliding contact wire will inevitably cause the power supply system of the full-automatic furnace ramming truck to jam, and even often cause damage to the sliding contact wire and its accessories, resulting in unsmooth circuit and affecting automatic walking. Content of the Utility Model

[0029] The following will describe the present invention in detail with reference to the accompanying drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. For the convenience of description, words such as "upper", "lower", "left", and "right" hereinafter only indicate the same directions as the upper, lower, left, and right directions of the accompanying drawings themselves, and do not limit the structure.
[0030] As Figure 1 , Figure 2 shown, a pantograph track structure provided in this embodiment includes a track 1, a transition section 2, a hanging buckle joint 3, a backing plate 4, a spring piece 5, a transition joint 6 and a pantograph 7.
[0031] As Figure 6As shown, the rail 1 is rolled from heat-resistant steel into an I-beam shape, enabling the rail 1 to have high-temperature resistance. Multiple first sliding grooves 11 penetrating along the first direction X are provided on the bottom plate of the I-beam-shaped rail 1, and a first installation groove 12 penetrating along the second direction Y is provided on the bottom plate of the I-beam-shaped rail 1. The first direction X and the second direction Y are perpendicular to each other in the same top-down projection plane.
[0032] As Figure 4 shown, the side walls forming the first sliding groove 11 include a first wall 13 and second walls 14 vertically connected to both ends of the first wall 13, and the bottom of the rail 1 forms a bottom wall 15.
[0033] As Figure 1 、 Figure 2 shown, the transition joint 2 is placed in the first installation groove 12. As Figure 7 shown, multiple second sliding grooves 21 penetrating along the first direction X are provided on the transition joint 2. A second installation groove 22 is provided on the inner bottom surface of the transition joint 2 forming the second sliding grooves 21. As Figure 2 shown, multiple first sliding grooves 11 and multiple second sliding grooves 21 are aligned one by one, and a sliding contact wire 7 is provided in each of the first sliding grooves 11 and the second sliding grooves 21. The sliding contact wire 7 has a gap & in the transition joint 2.
[0034] As Figure 5 、 Figure 8 shown, the suspension buckle joint 3 and the backing plate 4 are installed in each first sliding groove 11. The suspension buckle joint 3 includes a suspension buckle 31 and a mounting plate 32 horizontally placed on one side of the suspension buckle 31. The backing plate 4 includes a first plate 41 and a second plate 42 vertically connected, and the first plate 41 and the second plate 42 are an integral part. The side walls forming the first sliding groove 11 include a first wall 13 and second walls 14 vertically connected to both ends of the first wall 13, and the bottom wall 15 at the bottom of the rail 1 is vertically connected to the second wall 14.
[0035] The mounting plate 32 is connected to the first wall 13, the first plate 41 is connected to the second wall 14, the second plate 42 is connected to the bottom wall 15, the suspension buckle 31 is placed between the two first plates 41, and the sliding contact wire 7 is hooked to the suspension buckle 31 (as Figure 3 shown). The space between the two first plates 41 and the suspension buckle 31 is for the sliding contact wire 7 to pass through.
[0036] As Figure 4 、 Figure 7 、 Figure 11 shown, a spring piece 5 is provided in the second installation groove 22. As Figure 9As shown, the spring piece 5 includes an arc-shaped plate 51 and flat plates 52 connected to both ends of the arc-shaped plate 51. The flat plates 52 are placed in the second installation grooves 22, and the arc-shaped plate 51 protrudes towards the side of the flat plates 52.
[0037] As Figure 5 shown, a transition joint 6 is embedded in each of the second sliding grooves 21. The transition joint 2 forms an installation groove on the side wall of the second sliding groove 21. Two side walls of the transition joint 6 are placed in the installation groove, and the installation groove forms a guide for the up and down movement of the transition joint 6. As Figure 10 shown, the transition joint 6 is in an n shape so as to form a sliding cavity 61 inside it. The transition joint 6 is embedded in the middle position of the second sliding groove 21 so that the sliding cavity 61 is aligned with the second sliding grooves 21 at both ends. The sliding cavity 61 is clamped with the sliding contact wire 7.
[0038] As Figure 11 shown, the protruding arc-shaped plate 51 contacts the transition joint 6. The transition joint 6 is a metal key, and it can float up and down overcoming the elastic force of the spring piece 5. The transition joint 2, the hanging buckle joint 3, and the backing plate 4 are insulating parts (such as polytetrafluoroethylene insulating material). In this way, the hanging buckle joint 3 and the backing plate 4 form an insulating channel, and each is installed at the corresponding position of the track 1 through bolts. The insulating channel, the transition joint 6, and the track 1 together form a deformation control structure, which forms a stable guiding channel for the sliding contact wire that is prone to deformation, and in addition, this channel can also adapt to the expansion, contraction, and twisting deformation of the sliding contact wire 7 that deforms continuously with temperature in three-dimensional space
[0039] During installation, first install the sliding contact wire 7 in the first sliding groove 11, and directly fit the notch on the hanging buckle 31 with the notch on the sliding contact wire 7 (as Figure 3 shown). When the sliding contact wire 7 is inserted and reaches the position of the transition joint 2, let the sliding contact wire 7 press the transition joint 6 that can float up and down, and use the elastic force of the spring piece 5 to make the transition joint 6 in close contact with the sliding contact wire 7, playing a role in stable power supply with gap transition of the sliding contact wire 7.
[0040] The contact area between the track 1 and the sliding contact wire 7 is large, and there is only a small assembly gap between them. Therefore, the track 1 has a very strong guiding effect on the copper sliding contact wire that is prone to deformation, making the spatial position of the sliding contact wire 7 within the design tolerance range.
[0041] The heat-resistant track 1, transition section 2, transition joint 6 and insulation structure group adopted by the utility model form a deformation control structure, which can provide a stable guiding channel, control the spatial position of the sliding contact wire 7, and prevent the irregular deformation of the copper sliding contact wire 7. It can change continuously with temperature and provide a channel designed at the top layer for the expansion, contraction and twisting of the deformed sliding contact wire in three-dimensional space. The influence of the deformation force generated by the large difference in thermal expansion coefficient is eliminated, and stable power supply is realized in a high-temperature environment.
[0042] The gap & provides a space for the thermal expansion and contraction deformation of the sliding contact wire 7. The sliding contact wire 7 can freely expand and contract in the guiding channel provided by the deformation control structure, eliminate the deformation force, avoid twisting deformation, and ensure the smoothness of the circuit.
[0043] The utility model not only reduces the active deformation of the track 1, but also reduces the passive deformation of the sliding contact wire 7, and solves the problem of the power supply failure of the automatic tapping machine during automatic walking.
[0044] The above are only the embodiments of the utility model, and do not limit the patent scope of the utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the utility model.
