Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for tunnel lining trolleys, and more specifically, to a rapid positioning device for tunnel lining trolleys. Background Technology

[0002] During the construction of the secondary lining of a tunnel, a secondary lining trolley is usually required, and a positioning device is needed to position the trolley when laying its track.

[0003] Currently, commonly used tunnel lining trolley positioning devices can only mark the center position of the ground where the traveling track is laid, and then calculate the distance between the two traveling tracks before laying, which is time-consuming and laborious. For example, the tunnel lining trolley rapid positioning device disclosed in publication number CN215408687 U includes a gantry mechanism and a traveling mechanism set at the bottom of the gantry mechanism. A template mechanism is set around the gantry mechanism, and a support mechanism is also set between the template mechanism and the gantry mechanism. The gantry mechanism includes a gantry beam, and a positioning device is set on the gantry beam corresponding to the center position of the arch of the template mechanism.

[0004] As can be seen from the publicly available scheme, the positioning device marks the center position of the two walking tracks using positioning rays emitted by the device. Construction workers then use these rays to mark the tunnel centerline, calculate the positions of the walking tracks on both sides based on the centerline marks, draw construction lines, and finally lay the tracks. The entire positioning process is time-consuming and laborious, reducing the convenience of positioning. Utility Model Content

A construction template body 5 is movably connected to the outer side of the tunnel lining trolley body 4. A support plate is provided between the construction template body 5 and the tunnel lining trolley body 4. Several hydraulic telescopic columns are rotatably connected between the support plate and the tunnel lining trolley body 4. The tunnel lining trolley body 4 is equipped with a gantry body 41. A traveling wheel 42 is provided at the bottom of the gantry body 41. A traveling track 43 is movably connected to the bottom of the traveling wheel 42. The positioning device body 1 includes a positioning seat 11. A lifting assembly is threadedly connected to the top of the positioning seat 11. The lifting assembly includes a fixing plate 2. The side of the fixing plate 2 is fixedly connected to the surface of the gantry body 41. A screw hole 21 is opened on the surface of the fixing plate 2. A lifting rod 16 is threadedly connected to the inner wall of the screw hole 21. An extrusion sleeve 17 is threadedly connected to the surface of the lifting rod 16. The bottom of the pressure sleeve 17 contacts and presses against the top of the positioning seat 11, which can prevent the lifting rod 16 from rotating automatically. The lifting rod 16 can be raised and lowered by threads, thereby adjusting the height of the positioning seat 11 and the center block 31. A center line marking assembly is movably connected to the side of the positioning seat 11. The center line marking assembly includes a center rod 3. A center block 31 is fixedly connected to the bottom center position of the center rod 3. The center block 31 can be a marking block or a marker pen, which is convenient for marking the center position of the track and for detecting the center position of the track. The center block 31 is triangular in shape. The center of the center block 31 and the center of the distance between the two traveling tracks 43 are on the same straight line. A through hole 34 is opened on the surface of the center rod 3. A positioning rod 35 is movably connected to the inner wall of the through hole 34. One end of the positioning rod 35 is tightened with a manual knob by a screw. The center block 31 can directly mark the center position of the two traveling tracks 43, which improves the positioning efficiency.

[0027] One end of the center rod 3 has a telescopic groove 32. The inner wall of the telescopic groove 32 is slidably connected to an anti-detachment block 15. The anti-detachment block 15 can prevent one end of the crossbar 13 from detaching from the telescopic groove 32. The end face of the anti-detachment block 15 is fixedly connected to the crossbar 13. The surface of the crossbar 13 has adjustment holes 14. The adjustment holes 14 are evenly distributed and have internal threads on their inner walls. The telescopic groove 32 allows the center rod 3 and the crossbar 13 to extend and retract, thereby adjusting the total length. The two ends of the telescopic groove 32 are fixedly fitted with limit sleeves 33. The inner wall of the limit sleeve 33 is slidably connected to the surface of the crossbar 13. The limit sleeve 33 is made of wear-resistant rubber and has the function of limiting damping.

[0028] The bottom of the positioning seat 11 is provided with a positioning head 18. The bottom of the positioning head 18 is at the same height as the bottom of the center block 31. The positioning head 18 can be a marking block or a marker. The side of the positioning seat 11 is slidably connected to the surface of the gantry body 41. The side of the positioning head 18 is on the same plane as the inner surface of the travel track 43. The positioning head 18 can directly mark one side line of the travel track 43, and the track can be laid directly. The top of the positioning seat 11 is fixedly sleeved with a bearing 12. The inner ring of the bearing 12 is fixedly connected to one end of the lifting rod 16. One end of the lifting rod 16 is equipped with a manual rotation for easy manual rotation.

[0029] When using the tunnel lining trolley quick positioning device, the two lifting rods 16 at one end of the two symmetrical positioning seats 11 can be manually rotated clockwise to move the positioning seats 11 downwards. The downward movement of the positioning seats 11 causes the center rod 3 to move downwards, which in turn causes the positioning head 18 to move downwards and contact the tunnel ground. The downward movement of the center rod 3 causes the bottom of the center block 31 to contact the tunnel ground, thereby marking the center of the distance between the two walking tracks 43 and the sides of the two walking tracks 43. This facilitates the direct laying of the walking tracks 43. Moreover, the horizontal bar 13 and the center rod 3 are located at the bottom of the gantry body 41 and will not affect the movement of construction personnel. When it is necessary to adjust the extension position of the horizontal bar 13, the positioning rod 35 can be manually removed counterclockwise, and then the horizontal bar 13 can be moved to the appropriate position on both sides, so that the center rod 3 is in the center position of the two horizontal bars 13. Then, the positioning rod 35 and the adjustment hole 14 at that position can be manually tightened clockwise.
