Description

Technical Field

[0001] This utility model relates to the field of subway tunnels, and in particular to a clearance detection device for subway tunnel equipment. Background Technology

[0002] An existing patent (publication number: CN205905983U) discloses a clearance detection device for subway tunnel equipment, including a vehicle body with a support frame on the vehicle body. Clearance fixing plates are respectively set on both sides of the support frame. A clearance movable plate is hinged to the outer side of the clearance fixing plate. Two positioning plates are set on the support frame, and a transverse moving plate is set on each positioning plate. A guide rail pair is set between the transverse moving plate and the positioning plate. The outer side of each transverse moving plate is fixedly connected to the inner side of the clearance fixing plate. A nut is set on each of the two transverse moving plates, and a lead screw is screwed into the two nuts. A handwheel is set in the middle of the lead screw. The lead screw is a bidirectional lead screw, and the threads of the two nuts are opposite, so that the two transverse moving plates can move outward or inward simultaneously. The transverse moving plate is located in the middle of the support frame. Guide support rods and guide support seats are respectively provided at the upper and lower ends of both sides of the support frame. The guide support seats are respectively provided on the support frame and the clearance fixing plate. However, when this device is in use, it can only move the transverse moving plate outward or inward at the same time, and can only perform horizontal detection. It cannot perform clearance detection on the top of the tunnel. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a subway tunnel equipment clearance detection device that uses a horizontal center ruler, a horizontal side ruler, and a vertical detection ruler to perform clearance detection on both sides and the top of the tunnel, respectively. The detection on the sides of the tunnel can be slid up and down, while the detection on the top of the tunnel can be slid horizontally.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A clearance detection device for subway tunnel equipment includes a strip-shaped connecting rod, movable wheels, a strip-shaped connecting plate, a U-shaped frame plate, a rotating clamping plate, a vertical measuring ruler, a T-shaped insert, a support sleeve, a horizontal intermediate ruler, a horizontal connecting rod, and a horizontal side ruler. The strip-shaped connecting plate is connected to the side of the strip-shaped connecting rod, and the strip-shaped connecting rod is symmetrically arranged on both sides of the strip-shaped connecting plate. The lower part of the strip-shaped connecting rod is connected to the movable wheel, and a set of movable wheels is distributed at the lower part of the strip-shaped connecting rod. The lower part of the U-shaped frame plate is connected to the strip-shaped connecting rod. The side of the U-shaped frame plate has a T-shaped groove, and the T-shaped insert is adapted to the T-shaped groove. The T-shaped insert is inserted into the T-shaped groove and slides up and down in the T-shaped groove. The side of the T-shaped insert is connected to the insert side plate, and the side of the insert side plate has a support sleeve. The two ends of the horizontal connecting rod are connected to the insert side plate.

[0006] The horizontal connecting rod side rod is connected to the horizontal intermediate ruler. The horizontal intermediate ruler is adapted to the horizontal side ruler. The horizontal intermediate ruler is inserted into the horizontal side ruler and slides inside the horizontal side ruler. The side of the horizontal side ruler has a side toothed side edge. The side toothed side edge is connected to the side toothed handle. The horizontal side ruler is symmetrically arranged at both ends of the horizontal intermediate ruler. Beneficial effects

[0007] 1. In the clearance detection of subway tunnel equipment, this utility model comprises a movable frame consisting of a strip connecting rod, a moving wheel, a strip connecting plate, and a U-shaped frame plate. This frame serves as the installation base for the wiring detection device. A T-shaped plug is inserted into a T-shaped groove, allowing the plug side plate to be placed on the side of the U-shaped frame plate and slide up and down. The up and down movement of the plug side plate causes the support sleeve to move up and down. The two ends of the horizontal connecting rod are connected to the symmetrical plug side plates, allowing the symmetrical plug side plates and the horizontal connecting rod to move up and down simultaneously. The side rod of the horizontal connecting rod is connected to the horizontal intermediate ruler, causing the horizontal intermediate ruler to move up and down as the plug side plates move. The two ends of the horizontal intermediate ruler are inserted into the symmetrical horizontal side rulers. In the clearance detection of subway tunnel equipment, the horizontal intermediate ruler and the symmetrical horizontal side rulers form a retractable horizontal clearance detection device. This detection device detects both sides of the tunnel. The detection device is designed as a retractable structure, allowing detection of both sides of tunnels of different widths during use. In the clearance detection of subway tunnel equipment, the device can also be moved up and down to detect different heights on both sides of the tunnel.

[0008] 2. This utility model's rotating plate is connected to the side connecting ear via a rotating shaft, allowing the rotating plate to be mounted on the U-shaped frame and rotate. The upper part of the vertical measuring ruler passes through the limiting groove and the strip-shaped limiting hole. The limiting groove positions the vertical measuring ruler horizontally, allowing for the detection of different points on the tunnel top. After the detection is completed, the vertical measuring ruler is pulled down and the point position is changed for detection again. The upper part of the rotating plate is magnetically attached to the U-shaped frame, ensuring the alignment of the limiting groove and the strip-shaped limiting hole. This device uses a horizontal middle ruler, a horizontal side ruler, and a vertical measuring ruler to perform boundary detection on both sides and the top of the tunnel, respectively. The detection on both sides of the tunnel can be slid up and down, while the detection on the top of the tunnel can be slid horizontally. Attached Figure Description

In the clearance detection of subway tunnel equipment, the strip-shaped connecting rod 01, the moving wheel 02, the strip-shaped connecting plate 03, and the U-shaped frame plate 04 form a movable frame. The frame serves as the installation base for the wiring detection setup. The U-shaped frame plate 04 has a T-shaped groove 05 on its side. The T-shaped plug 11 is adapted to the T-shaped groove 05. The T-shaped plug 11 is inserted into the T-shaped groove 05, so that the plug side plate 12 is placed on the side of the U-shaped frame plate 04 and can slide up and down. The up and down movement of the plug side plate 12 causes the support sleeve 13 to move up and down. The T-shaped plug 11 slides up and down in the T-shaped groove 05. The side of the T-shaped plug 11 is connected to the plug side plate 12. The side of the plug side plate 12 has a support sleeve 13. The two ends of the horizontal connecting rod 15 are connected to the plug side plate 12. The two ends of the horizontal connecting rod 15 are connected to the symmetrical plug side plate 12, so that the symmetrical plug side plate 12 and the horizontal connecting rod 15 can move up and down simultaneously.

[0017] Example 2:

[0018] The horizontal connecting rod 15 of this utility model is connected to the horizontal intermediate ruler 14, so that the insert block side plate 12 moves up and down, driving the horizontal intermediate ruler 14 to move up and down. The horizontal intermediate ruler 14 is adapted to the horizontal side ruler 16. The horizontal intermediate ruler 14 is inserted into the horizontal side ruler 16 and slides inside the horizontal side ruler 16. The side of the horizontal side ruler 16 has a side tooth side edge 17, and the side tooth side edge 17 is connected to the side tooth handle 18. The horizontal side ruler 16 is symmetrically arranged at both ends of the horizontal intermediate ruler 14.
