Description

Technical Field

[0001] The utility model belongs to the technical field of support card protective cover detection, and in particular relates to a subway contact rail protective cover support card inspection device. Background Art

[0002] Currently, the support clips for subway contact rail shields are made of composite insulating material. These clips are typically spaced 500mm apart on the upper surface of the contact rail and serve as a device for securing and supporting the contact rail shield. With the common slot-connected shield and support clips, during initial installation or if the shield slips due to thermal expansion or contraction, the support clips may not engage in the shield slots. This can cause the contact rail shield to fall off or intrude, leading to rail failure and seriously impacting subway train safety. In the event that the support clips are not engaged in the shield slots, inspection and correction can generally only be performed through foot patrols, using inspection mirrors, or during shield maintenance. However, the large number of support clips makes correction difficult, and patrol inspections and maintenance are inefficient.

[0034] Reference Figures 1 to 2 , a subway contact rail protective cover support card inspection device includes a sliding seat 1 and a pressure rod 6 installed on the sliding seat 1, the sliding seat 1 is provided with a fixing plate 11 and a connecting piece, one end of the connecting piece is connected to the fixing plate 11, and the other end is equipped with a first roller group 3, the first roller group 3 contacts the side of the protective cover and can roll along the side of the protective cover, and a second roller group 4 is also installed on the connecting piece, the second roller group 4 contacts the top surface of the protective cover and can roll along the top surface of the protective cover, the first roller group 3 and the fixing plate 11 are respectively located on both sides of the protective cover, and one end of the pressure rod 6 is hingedly connected to the fixing plate 11. At this time, when the pressure rod 6 rotates downward, it can generate a certain downward pressure to press the protective cover down until the upper end of the support card is stuck in the protective cover slot.

[0035] Specifically, a pressure wheel 7 is mounted on the pressure rod 6, and the pressure wheel 7 is located above the protective cover. A third roller group 5 is installed at the lower end of the fixed plate 11, and the third roller group 5 can contact the bottom surface of the support card and roll along the bottom surface of the support card, or when the movement is smooth, it is located below the support card and has a small distance between the support card and the support card. When the movement is stuck, when the pressure rod 6 is rotated downward, the pressure wheel 7 can press the protective cover down to the upper end of the support card and snap into the protective cover slot. The maximum diameter of the pressure wheel 7 is larger than the diameter of the pressure rod 6. In the process of rotating the pressure rod 6 downward, at least part of the structure of the pressure wheel 7 can rotate to below the bottom surface of the second roller 41, thereby generating a downward pressure on the protective cover. It can be set that when the pressure rod 6 is horizontal, the bottom end of the pressure wheel 7 is lower than the bottom surface of the second roller 41. The overall structural state of the subway contact rail protective cover support card inspection device of this scheme when the pressure rod 6 is rotated downward to the pressure rod 6 being horizontal can be referred to the attached Figure 1 shown.

[0036] The subway contact rail protective cover support card inspection device of this solution has a simple structure and is easy to carry and use. When inspecting the connection structure between the support card and the protective cover, it can quickly detect whether the support card is embedded in the protective cover slot and correct the support card that is not embedded in the protective cover slot, which can improve the inspection efficiency. There is no need to manually determine whether the support card is embedded in the protective cover slot, which reduces labor costs. When the upper end of the support card is not embedded in the protective cover, the distance between the bottom surface of the support card and the upper end surface of the protective cover is large, which can cause the movement of the sliding seat 1 to become stuck. When in use, the protective cover is pushed to move along the track. When the sliding seat 1 is stuck relative to the protective cover, the support card is not embedded in the protective cover slot. By pressing the pressure rod 6 downward, the protective cover can be pressed down and the corresponding structure on the support card can be stuck in the protective cover slot. There is no need to frequently bend down to check and remove the protective cover. The comprehensive inspection and rectification are integrated, which greatly improves the work efficiency of inspection and maintenance.

[0037] Specifically, the third roller group 5 includes at least two third rollers 51 spaced apart and a central axis corresponding to each of the third rollers 51. The third rollers 51 are guide pulleys. Each of the third rollers 51 can contact the bottom surface of the support card and roll along the bottom surface of the support card. One end of each of the central axes passes through each of the third rollers 51 and is detachably fixedly connected to the fixed plate 11. By having each roller fit the protective cover for rolling inspection, not only is the labor intensity of the workers reduced, but also the risk of frequent disassembly and assembly of the protective cover, resulting in a decrease in clamping force and intrusion into the driving limit, is reduced. The sliding seat 1 is provided with pulleys on the top and side surfaces of the protective cover and fits the protective cover, resulting in better stability during the movement process. The guide pulley is installed to fit the bottom surface of the support card, and the guide pulley will not damage the support card body when the pressure rod 6 is pressed downward.

[0038] Specifically, two parallel and spaced-apart first clips 14 are protruded from one side of the fixed plate 11 near the pressure rod 6. The two first clips 14 are vertically arranged and located on the same horizontal plane. A rotating block 10 is mounted between the two first clips 14. The rotating block 10 has a cube or rectangular structure, with a square vertical cross-section and a square or rectangular horizontal cross-section. First connecting shafts 8 are protruded horizontally from two opposing vertical first side surfaces of the rotating block 10. The first connecting shafts 8 are connected to the rotating block 10 using a conventional detachable connection method to prevent them from falling off during use. The two first connecting shafts 8 are rotatably inserted into first through holes 141 on the two first clips 14, respectively. The two first through holes 141 are coaxial and horizontally arranged. The end of the pressure rod 6 near the pressure wheel 7 is provided with two parallel and spaced second clips 62. The two second clips 62 are both arranged horizontally and located on the same vertical plane. The rotating block 10 can be relatively embedded between the two second clips 62. The two oppositely arranged second side surfaces of the rotating block 10 are respectively connected to the two second clips 62 and are parallel to each other. The two second connecting shafts 9 respectively pass through the second through holes 62 in the two second clips 62 and connect to the second side surfaces. Conventional detachable connection methods can be used to prevent them from falling off during use. The spacing between the two second side surfaces is adapted to the spacing between the two second clips 62. The pressure rod 6 can rotate up and down around the axis of the first connecting shaft 8 without slipping relative to the rotating block 10 when rotating up and down. The two second through holes 62 are coaxially arranged and perpendicular to the axis of the first through hole 141. The spacing between the two second side surfaces can be set according to actual usage and can be set relative to the vertical length of the first clip 14 so that it is greater than, less than, or equal to the vertical length of the first clip 14. The first clamping plate 14 can limit the left and right rotation of the pressing rod 6 to a certain extent, so as to prevent the pressing rod 6 from colliding with the second rod body 22 .

[0039] Specifically, the sliding seat 1 also includes a mounting plate 13 connected to the fixed plate 11, and each end of the center axis away from the fixed plate 11 is detachably fixedly connected to the mounting plate 13, and each of the third rollers 51 is located between the fixed plate 11 and the mounting plate 13 and the upper end is protruded from the upper end of the mounting plate 13.

[0040] Specifically, the sliding seat 1 further includes a bottom plate 12 , one end of which is fixedly connected to the fixing plate 11 , and the bottom of the mounting plate 13 is fixed on the bottom plate 12 .

The base body is mainly formed by an L-shaped first fixing block, a second fixing block, and a third fixing block made of aluminum alloy, which are connected in sequence and fixed by bolts. When the first roller group 3, the second roller group 4, and the third roller group 5 are each equipped with two rollers, the pressure rod 6 is hingedly connected to the upper end of the second fixing block, a second rod body 22 is detachably fixedly connected to the first fixing block, and another second rod body 22 is detachably fixedly connected to the third fixing block. The mounting plate 13 includes a first plate body, a second plate body, and a third plate body connected in sequence. The first plate body is mounted on the first fixed block, the second plate body is mounted on the second fixed block, and the third plate body is mounted on the third fixed block. A third roller 51 is mounted between the first plate body and the first fixed block, and another third roller 51 is mounted between the third plate body and the third fixed block, which is convenient for determining the installation position of each roller and the pressure rod 6, and is convenient for manufacturing and assembly.

[0042] Specifically, the connecting member includes at least two connecting rods 2 arranged at intervals, one end of the connecting rod 2 is detachably fixed to the fixed plate 11, the first roller group 3 is provided with a first roller 31 corresponding one-to-one to each of the connecting rods 2, and each of the first rollers 31 is rotatably mounted on each of the connecting rods 2; the second roller group 4 is provided with a second roller 41 corresponding one-to-one to each of the connecting rods 2, and each of the second rollers 41 is rotatably mounted on each of the connecting rods 2.

[0043] Specifically, each connecting rod 2 includes a first rod body 21 and a second rod body 22 connected in sequence in an L-shape. One end of the second rod body 22 is detachably fixed to the fixing plate 11, and the other end is connected to the upper end of the first rod body 21. Each first roller 31 is rotatably mounted on each first rod body 21, and each second roller 41 is rotatably mounted on each second rod body 22. The spacing between the second rod bodies 22 and 12 can be set according to the actual size of the protective cover.

[0044] Specifically, a limiting member 61 is detachably mounted on the pressing rod 6 , and the limiting member 61 is located on a side of the pressing wheel 7 away from the fixing plate 11 .

[0045] When in use, first put the subway contact rail protective cover support card inspection device of this scheme on the protective cover, ensure that the rollers above the protective cover, the rollers on the side are in contact with the surface of the protective cover, and the rollers at the bottom can push the protective cover support card inspection device through the pressure rod 6. When the sliding seat 1 is stuck, the pressure rod 6 uses the top surface of the protective cover as a lever point and uses the lever principle to press the protective cover downward relatively, so that the upper end of the support card is relatively pushed into the protective cover slot.

[0046] Specifically, when tightening each node connected by bolts and nuts, flat washers or spring washers and nuts can be installed on the bolts, mainly to increase the contact area and prevent the nuts from loosening.
