Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a subway measurement device. Background Art

[0002] Subway clearance inspection refers to various inspections of underground passages and subway line facilities before operation, during construction, and during the operation of existing lines. Its purpose is to ensure the safety and stability of subway construction and operation and avoid various accidents. At present, common measuring devices are used to measure the limits on both sides of subway platforms to avoid the limits being too narrow, causing scratches when the subway passes through, and to avoid the limits being too wide, which is inconvenient for people to get on and off the subway on a daily basis.

[0003] The existing subway boundary measuring device can measure subway platforms at different heights. In actual measurement operations, the measurement is mainly performed by manual operation. During measurement, the detection rod of the measuring device needs to be adjusted in height according to the measurement height. After the adjustment is completed, the detection rod is unfolded manually and moved to the top edge of the platform. Then the scale is observed and recorded. After completion, the whole device is folded up to complete the measurement operation. This makes the entire measurement process time-consuming and affects the measurement efficiency. Therefore, a subway measuring device is proposed. Utility Model Content

[0008] Furthermore, a locking screw penetrating into the interior is provided on one side of the outer surface of the fixing rod, and the locking screw is threadedly connected to the fixing rod and abuts against the outer wall of the slide rail, so that the slide rail can be abutted and fixed, thereby completing the position fixation of the movable rod.

[0009] Furthermore, the two detection components each include an installation groove, and the installation groove is opened at the bottom of the movable rod, and two springs are symmetrically fixedly connected to the inner top of the installation groove, and the bottoms of the two springs are commonly fixedly connected to a detection plate, and the detection plate and the installation groove are sealed and slidable, and a non-self-locking touch switch is fixedly installed on the inner top of the installation groove, and the non-self-locking touch switch can automatically reset after the contact limit.

Based on the embodiments of 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.

[0021] like Figures 1 to 3 As shown, it relates to a subway measuring device, including a frame 1, a column 3 is fixedly connected to the top of the frame 1, and travel grooves 11 are opened on both sides of the outer surface of the column 3. A lifting assembly is installed between the two travel grooves 11 and the frame 1. The two lifting assemblies include an electric push rod 10, and the electric push rod 10 is fixedly installed on the top of the frame 1 and arranged on the inner side of the travel groove 11. The movable end of the electric push rod 10 is fixedly connected to a sliding rod 9, and the sliding rod 9 is slidably connected to the travel groove 11, and a laser ranging sensor 8 is fixedly embedded on one side outer wall of the sliding rod 9. The laser ranging sensor 8 is a prior art, and the corresponding model can be selected according to actual work requirements. A receiving groove is opened at the bottom of the sliding rod 9, and the electric push rod 10 is arranged inside it, so that the overall height of the sliding rod 9 is reduced after it is lowered and contracted.

[0022] The movable ends of the two lifting assemblies are fixedly installed with telescopic rods, and the two telescopic rods include a fixed rod 7, and the fixed rod 7 is fixedly installed on the top of the sliding rod 9. The bottom of the fixed rod 7 is slidably connected to the slide rail 5, and the bottom of the slide rail 5 is fixedly connected to the movable rod 6. One side of the outer surface of the fixed rod 7 is provided with a locking screw 4 that penetrates into the interior, and the locking screw 4 is threadedly connected to the fixed rod 7 and abuts against the outer wall of the slide rail 5. When not in use, the movable rod 6 and the fixed rod 7 are mostly overlapped, which can reduce the occupied space and facilitate transportation and storage.

[0023] A detection component is fixedly installed at the bottom of the movable ends of the two telescopic rods. The two detection components include a mounting groove 14, and the mounting groove 14 is opened at the bottom of the movable rod 6. Two springs 16 are symmetrically fixedly connected to the inner top of the mounting groove 14. A detection plate 13 is fixedly connected to the bottom of the two springs 16. The detection plate 13 and the mounting groove 14 are sealed and slidable. A non-self-locking touch switch 15 is fixedly installed at the inner top of the mounting groove 14. The non-self-locking touch switch 15 is activated when pressure is applied and automatically resets when the pressure is released.

[0024] The bottom of the frame 1 is symmetrically rotatably connected with four track wheels 12, and a handrail 2 is fixedly installed on one side of the top of the frame 1 to facilitate pushing the frame 1 to move along the subway track.

[0025] Working principle: When put into use, the whole is erected on the subway track, and then the electric push rod 10 pushes the slide bar 9, and the slide bar 9 drives the telescopic rod to rise until it reaches the set height, and then loosens the locking screw 4, and then moves the movable rod 6 until the movable rod 6 moves to the set position, and then tightens the locking screw 4, and the locking screw 4 cooperates with the slide rail 5 to fix the movable rod 6, and then pushes the whole to move along the subway track through the handrail 2. When the detection point is reached, the lifting assembly drives the telescopic rod to descend, and when the detection plate 13 contacts the subway platform pavement, the detection plate 13 is pressed into the installation groove 14 until the non-self-locking touch switch 15 is pressed, the lifting assembly stops running, and the laser ranging sensor 8 detects the distance between the edge of the subway platform and the slide bar 9, thereby obtaining the boundary spacing on both sides of the subway platform, and then resets, and then continues to push the whole to move along the subway track until the next detection point.
