Description

Technical Field

[0001] The utility model relates to the technical field of switch machine detection tools, in particular to an auxiliary detection tool for indicating a notch of a switch machine. Background Art

[0002] With the rapid development of urban rail transit in my country, the signal system, as the core equipment for controlling operational safety, has become particularly important for analysis and evaluation of its safety and reliability. Among them, turnouts are the core part of the signal interlocking system. With turnouts, the line's capacity can be fully utilized.

[0003] However, due to the large number of turnouts, complex structure, high difficulty and cost of maintenance, train speed and driving safety are restricted, which is a common failure point. As an important parameter in switch maintenance, if the gap value of the switch detection rod is too large or too small, the switch will not be able to lock, resulting in the turnout being unable to operate in place, commonly known as "stuck gap". Once a failure occurs, it will affect the subway operation and passenger safety.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an auxiliary detection tool for the switch machine indication gap is proposed. Utility Model Content

[0007] Preferably, a through hole is provided at the bottom of the base, a connecting plate is fixedly connected to the top of the base, a threaded rod is connected to the internal thread of the connecting plate, a moving rod is fixedly connected to the bottom of the threaded rod, a horizontal rod is fixedly connected to one side of the base, and a scale is fixedly connected to the surface of the horizontal rod.

[0008] Preferably, the detection rod is located on the movement track of the clamping block, and the clamping block and the detection rod are arranged perpendicular to each other.

[0009] Preferably, the size of the hollow hole is larger than the right side convex block of the indicator mark, and the bottom of the notch is flush with the top of the indicator mark.

[0010] Preferably, the lifting plate is in a stationary state under the action of the spring and the nut, and the surface of the handle is wrapped with an anti-slip ring.

[0011] Preferably, the through hole corresponds to the position of the motion rod, and the motion rod forms a lifting structure inside the motion rod through the threaded rod.

[0012] Preferably, the scale is located at the midpoint of the horizontal rod, and the scale is parallel to the side of the base.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By setting a card block and pushing the slider to move along the base toward the switch machine body, the card block will slide along the indicator mark toward the inside of the gap, and the hollow hole will gradually cover the convex block on the indicator mark. At this time, when the gap is within the standard range, the card block can be completely inserted into the gap and leave a margin between the hollow hole and the indicator mark convex block. When the gap is not within the standard range, the card block cannot be inserted into the gap, indicating that the gap offset must be adjusted in time and re-tested until it can be completely inserted.

[0015] By setting up a moving rod, in order to avoid the base being placed unevenly and affecting the test results, the liquid inside the horizontal rod can be observed to see whether it is located at the scale position. If the liquid is on the right side of the scale at this time, it means that the base is tilted to the right. At this time, the two sets of threaded rods on the right side can be twisted to control the moving rod to descend. The moving rod then passes through the through hole and descends, and contacts the ground. Under the action of the moving rod, the downward-tilted part of the right side of the base will move upward, so as to adjust the base to a flat state. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: Figure 1-Figure 5 As shown, an auxiliary detection tool for indicating a notch of a switch machine comprises a ground 1, a switch machine body 2 is placed on the top of the ground 1, a notch 3 is arranged on the surface of the switch machine body 2, an indicator mark 4 is placed on the top of the ground 1 and is located on one side of the switch machine body 2, a base 5 is placed on one side of the indicator mark 4 and is located on the top of the ground 1, two groups of sliders 6 are slidably connected to the top of the base 5, connecting rods 7 are fixedly connected to the tops of the two groups of sliders 6, lifting plates 8 are slidably connected to the surfaces of the two groups of connecting rods 7, springs 9 fixedly connected to the sliders 6 are fixedly connected to the bottoms of the two groups of lifting plates 8, nuts 10 threadedly connected to the connecting rods 7 are affixed to the tops of the two groups of lifting plates 8, a detection rod 11 is fixedly connected to one end of the lifting plate 8, a hollow hole 12 is provided at the bottom of the detection rod 11, a block 13 is fixedly connected to one end of the detection rod 11, and a handle 18 is fixedly connected to the top of the lifting plate 8.

[0024] In this embodiment, the detection rod 11 is located on the movement trajectory of the block 13, and the block 13 and the detection rod 11 are arranged perpendicular to each other. The lifting plate 8 is controlled to descend horizontally along the connecting rod 7, and the lifting plate 8 drives the block 13 to descend. After the block 13 descends, it will fit with the protrusion on the indicator mark 4.

[0025] In this embodiment, the size of the hollow hole 12 is larger than the right side protrusion of the indicator mark 4, and the bottom of the notch 3 is flush with the top of the indicator mark 4. At this time, when the notch 3 is within the standard range, the block 13 can be completely inserted into the notch 3 and leave a margin between the hollow hole 12 and the protrusion of the indicator mark 4. When the notch 3 is not within the standard range, the block 13 cannot be inserted into the notch 3, indicating that the notch 3 is offset.

[0026] In this embodiment, the lifting plate 8 is in a stationary state under the action of the spring 9 and the nut 10, the surface of the handle 18 is wrapped with an anti-slip ring, and the nut 10 is rotated to make it fit with the lifting plate 8, so as to prevent the lifting plate 8 from moving upward when the notch 3 is detected.

[0027] Embodiment 2: Figure 3-Figure 5 As shown, a through hole 14 is provided at the bottom of the base 5, a connecting plate 15 is fixedly connected to the top of the base 5, a threaded rod 16 is connected to the inner thread of the connecting plate 15, a moving rod 17 is fixedly connected to the bottom of the threaded rod 16, a horizontal rod 19 is fixedly connected to one side of the base 5, and a scale 20 is fixedly connected to the surface of the horizontal rod 19.

[0028] In this embodiment, the through hole 14 corresponds to the position of the moving rod 17. The moving rod 17 forms a lifting structure inside the moving rod 17 through the threaded rod 16. The two groups of threaded rods 16 on the right are screwed to control the moving rod 17 to descend. The moving rod 17 then passes through the through hole 14 and descends, and contacts the ground 1. Under the action of the moving rod 17, the downwardly inclined part of the right side of the base 5 will move upward, thereby adjusting the base 5 to a flat state.

[0029] In this embodiment, the scale 20 is located at the midpoint of the horizontal rod 19, and the scale 20 is parallel to the side of the base 5. The liquid inside the horizontal rod 19 can be observed to check whether it is located at the position of the scale 20. If the liquid is located on the right side of the scale 20 at this time, it means that the base 5 is tilted to the right.

[0030] Working principle: First, when it is necessary to detect whether the indicator mark 4 is aligned with the notch 3 on the switch machine to determine whether the switch can be locked, the equipment is moved to the designated ground 1, and the center line of the card block 13 and the midpoint of the notch 3 are on the same horizontal line. At this time, the handle 18 can be pushed downward to control the lifting plate 8 to descend horizontally along the connecting rod 7. The lifting plate 8 then drives the card block 13 to descend. After the card block 13 descends, it will fit with the convex block on the indicator mark 4. At this time, the nut 10 can be rotated to fit it with the lifting plate 8, so as to prevent the lifting plate 8 from moving to the The block 13 will move upward, at this time, push the slider 6 to move along the base 5 toward the switch machine body 2, and the block 13 will slide along the indicator mark 4 toward the inside of the notch 3, and the hollow hole 12 will gradually cover the protrusion on the indicator mark 4. At this time, when the notch 3 is within the standard range, the block 13 can be completely inserted into the notch 3 and leave a margin between the hollow hole 12 and the protrusion of the indicator mark 4. When the notch 3 is not within the standard range, the block 13 cannot be inserted into the notch 3, indicating that the deviation of the notch 3 must be adjusted in time and re-tested until it can be completely inserted.

[0031] During the inspection, in order to avoid the base 5 being placed unevenly and affecting the inspection results, the liquid inside the horizontal rod 19 can be observed to see whether it is located at the position of the scale 20. If the liquid is located on the right side of the scale 20 at this time, it means that the base 5 is tilted to the right. At this time, the two sets of threaded rods 16 on the right side can be screwed to control the movement rod 17 to descend. The movement rod 17 then passes through the through hole 14 and descends, and contacts the ground 1. Under the action of the movement rod 17, the downwardly tilted part of the right side of the base 5 will move upward, thereby adjusting the base 5 to a flat state.

[0032] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
