Technical Field

[0001] The present application relates to the field of contact network groove positioning technology, and in particular to a contact network groove positioning device. Background Art

[0002] The high-speed railway contact network is a power supply network erected above the railway line. The current that high-speed trains rely on is transmitted through the contact network at the top. In railway tunnels, the installation of contact networks is currently prohibited from being implanted in the form of post-implantation, and all installations are carried out in the form of pre-buried grooves.

[0003] The construction process of the embedded groove includes the assembly and welding of multiple embedded grooves in the groove group. During the installation of the contact network, the assembly and welding quality requirements of the groove group are particularly strict, and the multiple embedded grooves in the groove group need to maintain accurate parallelism and spacing.

[0004] If the spacing between the grooves does not meet the design requirements during construction or the grooves have defects such as "eight" shape during installation, the entire slab of concrete will need to be removed, which will result in a huge waste of construction time and materials. Summary of the invention

[0005] In order to improve the assembly welding quality of the contact network groove group, the present application provides a contact network groove positioning device.

[0008] By adopting the above technical scheme, since the projections of the through opening surfaces of the positioning grooves corresponding to at least two positioning plates along the length direction of the positioning frame all overlap with each other, when assembling and welding the multiple reserved grooves of the contact network groove group, the multiple reserved grooves are respectively placed in the positioning grooves corresponding to at least two positioning plates, so that the multiple reserved grooves can be made parallel to each other, thereby ensuring the accuracy of the parallelism of the multiple reserved grooves; at the same time, the fixed spacing between the multiple positioning grooves on the positioning plate allows the multiple reserved grooves to maintain an accurate spacing between them, so as to avoid the situation where the spacing between the grooves does not meet the design requirements during construction or the grooves appear "eight"-shaped during installation. The defects and the like, thereby improving the assembly and welding quality of the contact network groove group.

[0012] By adopting the above-mentioned technical solution, the positioning plate is moved to make the sliding rod slide relative to the sliding channel. After sliding to the appropriate position, the locking bolt is turned to make it press against the transition surface between the large end and the small end of the sliding channel to lock the sliding of the sliding rod relative to the supporting frame, so that after the positioning plate slides relative to the supporting frame, a groove can be reserved for stable positioning and placement.

[0013] Optionally, the edges of the positioning grooves of the positioning plate are provided with stabilizing members, and the stabilizing members are used to clamp and fix the embedded grooves in the positioning grooves.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a contact network groove positioning device. Figure 1 A contact network channel positioning device includes a positioning frame 1 and three positioning plates 2, and the three positioning plates 2 are all arranged on the positioning frame 1. The positioning frame 1 includes a support frame 11 and a bearing frame 12. The support frame 11 includes four legs 111, and the four legs 111 are all arranged vertically. A connecting rod 112 is fixedly connected between two adjacent brackets, and the connecting rod 112 is arranged horizontally. The bearing frame 12 is a rectangular frame structure, and the four legs 111 are respectively fixedly connected to the four corners of the bearing frame 12 and are perpendicular to the bearing frame 12.

[0032] Reference Figure 1 The positioning frame 1 is provided with a walking mechanism 6, which includes four pulleys 61, which are respectively rotatably connected to the lower ends of the four legs 111, and the rotation planes of the four pulleys 61 are perpendicular to the plane where the carrier frame 12 is located. The walking mechanism 6 makes it easier to push and move the positioning frame 1, so as to facilitate adjustment and transfer to improve convenience and practicality.

[0033] Reference Figure 1The three positioning plates 2 are all arranged perpendicularly to the carrier frame 12 and perpendicular to the length direction of the carrier frame 12, and the three positioning plates 2 are arranged at intervals along the length direction of the carrier frame 12. Three positioning grooves 3 are opened on the upper edges of the three positioning plates 2, and the opening direction of the positioning grooves 3 is vertically upward, and the positioning grooves 3 are arranged through the groove walls on both sides of the length direction of the carrier frame 12. The positioning grooves 3 of the three positioning plates 2 are arranged corresponding to each other, and the projections of the through opening surfaces of the corresponding positioning grooves 3 of the three positioning plates 2 along the length direction of the positioning frame 1 overlap with each other.

[0034] Since the projections of the through opening surfaces of the positioning grooves 3 corresponding to the three positioning plates 2 along the length direction of the positioning frame 1 all overlap with each other, when assembling and welding the multiple reserved grooves of the contact network groove group, the multiple reserved grooves are respectively placed in the positioning grooves 3 corresponding to the three positioning plates 2, so that the multiple reserved grooves can be parallel to each other, thereby ensuring the accuracy of the parallelism of the multiple reserved grooves; at the same time, the fixed spacing between the multiple positioning grooves 3 on the positioning plate 2 can maintain an accurate spacing between the multiple reserved grooves, so as to avoid the situation where the spacing of the grooves does not meet the design requirements during the construction process or the grooves appear "eight"-shaped during the installation process. The assembly and welding quality of the contact network groove group is improved.

[0035] Reference Figure 1 and Figure 2 Since the reserved grooves have different length specifications, for example, reserved grooves with length specifications of 1.5m and 2.5m, in order to improve the applicability of assembly and welding of reserved grooves with different length specifications, the three positioning plates 2 are all slidably connected to the supporting frame 12, and sliding locking parts 4 are provided between the three positioning plates 2 and the supporting frame 12.

[0036] Reference Figure 1 and Figure 2 The cross-sectional profiles of the two long sides of the carrier 12 are both L-shaped, and the L-shaped openings of the two long sides are arranged opposite to each other. The two long sides of the carrier 12 are both provided with sliding channels 121, and the two sliding channels 121 are both extended along the length direction of the carrier 12, and the inner wall profile of the sliding channel 121 is stepped with the small end at the top.

[0037] Reference Figure 1 and Figure 2 Two sliding locking members 4 are arranged on one positioning plate 2. The sliding locking members 4 include a sliding rod 41 and a locking bolt 42. The locking bolt 42 is sleeved and threadedly connected to the sliding rod 41. The two sliding rods 41 are fixedly connected to the lower edge of the positioning plate 2. The two sliding rods 41 are arranged vertically. The two sliding rods 41 on the same positioning plate 2 are respectively correspondingly penetrated and slide on the small end of the sliding channel 121. The locking bolt 42 is located at the large end of the sliding channel 121.

[0038] When positioning the reserved grooves of different lengths, move the positioning plate 2 so that the sliding rod 41 slides relative to the sliding channel 121 and slides to the appropriate position to adjust the spacing between the three positioning plates 2. Tighten the locking bolt 42 to press against the transition surface between the large end and the small end of the sliding channel 121 to lock the sliding of the sliding rod 41 relative to the support frame 12, so that the positioning plate 2 can be stably positioned in the reserved groove after sliding relative to the support frame 12. The above process allows the positioning plate 2 to better adapt to the length of the reserved groove, more stably position and place the reserved grooves of different lengths, and improve practicality.

[0039] Reference Figure 1 , since the reserved grooves usually include arc grooves and straight grooves, when the arc groove is placed on the positioning groove 3, the arc opening of the arc groove is vertically downward, and the arc groove contacts the groove wall of the positioning groove 3 with a curved surface, and its force-bearing area is small and the force is unbalanced. The reserved groove is easy to slide relative to the positioning groove 3, which affects its final assembly welding quality. In order to improve the assembly welding quality of the arc groove, the edges of the positioning grooves 3 of the two outermost positioning plates 2 are provided with stabilizing members 5, and the stabilizing members 5 of the two positioning plates 2 are respectively located on the side walls of the two positioning plates 2 that are away from each other.

[0040] Reference Figure 1 The stabilizing member 5 includes two stabilizing plates 51 and two stabilizing bolts 52. The two stabilizing plates 51 are fixedly connected to the positioning plate 2 and are perpendicular to the positioning plate 2. The two stabilizing plates 51 are located on both sides of the through opening of the positioning groove 3. The two stabilizing bolts 52 are respectively correspondingly penetrated and threadedly connected to the stabilizing plates 51. The two stabilizing bolts 52 are used to tighten the embedded grooves in the positioning groove 3.

[0041] After the reserved groove is placed in the positioning groove 3, the reserved groove is also located between the two stabilizing plates 51. At this time, tightening the stabilizing bolt 52 can clamp and fix the reserved groove to reduce the possibility of the arc groove sliding relative to the positioning groove 3, thereby improving the assembly welding quality of the arc groove.

[0042] Reference Figure 1 In order to improve the convenience of welding the reserved groove, a placement piece 7 is provided on one short side of the carrier frame 12. The placement piece 7 includes a mounting plate 71, a placement frame 72 and two diagonal braces 73. The mounting plate 71 is fixedly connected to the edge of one short side of the carrier frame 12, and the mounting plate 71 is perpendicular to the carrier frame 12. The placement frame 72 is fixedly connected to the upper part of the mounting plate 71, and the placement surface of the placement frame 72 is perpendicular to the mounting plate 71. The two diagonal braces 73 are parallel to each other and fixedly connected to the mounting plate 71 and the placement frame 72 at the same time.

[0043] The mounting plate 71 and the diagonal support rod 73 enable the placement frame 72 to be stably fixedly connected to the positioning frame 1, so that the placement frame 72 can stably carry the welding tool. Placing the welding tool on the positioning frame 1 through the placement member 7 can improve the convenience of welding the reserved groove and improve the welding efficiency.

[0044] Reference Figure 1 The upper edge of the mounting plate 71 is also provided with three positioning grooves 3, which correspond to the three positioning grooves 3 on the positioning plate 2. The projections of the through openings of the positioning grooves 3 corresponding to the mounting plate 71 and the positioning plate 2 along the length direction of the positioning frame 1 overlap with each other. When positioning, assembling and welding a longer embedded channel, the embedded channel can also be placed in the positioning groove 3 of the mounting plate 71, further improving the applicability and practicality of the embedded channel assembly welding.

[0045] The implementation principle of a contact network slot positioning device in the embodiment of the present application is as follows: multiple reserved slots are placed in the corresponding positioning slots 3 of three positioning plates 2 respectively, so that multiple reserved slots can be parallel to each other, thereby ensuring the accuracy of parallelism of multiple reserved slots; at the same time, the fixed spacing between multiple positioning slots 3 on the positioning plate 2 allows the multiple reserved slots to maintain an accurate spacing, so as to avoid the situation where the spacing of the slots does not meet the design requirements during the construction process or the slots appear "eight"-shaped during the installation process. The assembly and welding quality of the contact network slot group is improved. In addition, the sliding locking of the positioning plate 2 relative to the support frame 12 and the clamping and fixing of the reserved slots by the fixing bolts 52 can improve the applicability and practicality of assembling and welding of slots of different length specifications and arc shapes.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
