Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a subway tunnel section rapid wiring positioning device. Background Art

[0002] When installing brackets and pipelines in a track tunnel section, the center line of the track is usually used as the axis, and the track plane is used as the horizontal starting plane to install brackets on both sides and the top of the tunnel. During the bracket installation process, a laser wiring instrument is usually used to assist in positioning, thereby improving the accuracy and efficiency of bracket installation and ensuring that the bracket installation complies with the specifications.

[0003] The temporarily placed laser wiring instrument has the disadvantages of discontinuity and poor stability. It needs to be repositioned at certain distances, which seriously affects the installation efficiency of the bracket. In order to solve this problem, some construction teams choose to fix the laser wiring instrument on the top of the rail car, and adjust the wiring positioning point by adjusting the relative position of the laser wiring instrument on the rail car. Although this method improves the efficiency of wiring positioning to a certain extent, there are still problems with the complex adjustment method and low adjustment efficiency of the laser wiring instrument. At the same time, due to the different spacing requirements between pipelines of different specifications, the laser wiring instrument in the above-mentioned device cannot be adjusted synchronously and equidistantly. When facing the wiring positioning of pipelines with different spacing requirements, different positioning devices need to be used, resulting in low utilization of the device and increased construction costs.

When facing pipes of different specifications, the spacing between the laser wiring instruments 14 in the laser wiring instrument group is adjusted. After expanding to a suitable position, the laser wiring instruments 14 are started, so that each laser wiring instrument 14 can be expanded accordingly according to the specifications of different pipes.

[0056] By setting up mobile components, the subway tunnel section rapid wiring positioning device can be moved along the subway track. There is no need to repeatedly debug the laser wiring instrument group due to position changes, which improves work efficiency.

[0057] The utility model uses multiple laser wiring instruments to perform wiring positioning at the same time, thereby improving the efficiency of wiring positioning; the spacing between these laser wiring instruments is adjustable to accommodate pipes of different specifications, and rapid and accurate wiring positioning of the entire airspace can be achieved during the electromechanical installation process.

[0058] According to an embodiment of the present utility model, the fixing member includes: a fixing frame 12, a first bracket 21, and a second bracket 22; the first bracket 21 and the second bracket 22 are respectively connected to two ends of the fixing frame 12;

[0059] The laser wiring instrument group includes: an equivariable distance deployment component, a plurality of horizontal frames 13;

[0060] The equivariable-distance deployment assembly is disposed between the first bracket 21 and the second bracket 22;

[0061] A rectangular groove is formed on the top of the horizontal frame 13, and a laser wiring device 14 is fixed inside the rectangular groove;

[0064] According to one embodiment of the utility model, the equivariable distance deployment assembly includes:

[0065] A connecting rod mechanism 19, a double threaded rod 16, a guide rod 23; a first intermediate block 20, a plurality of moving blocks 18, a second intermediate block 24, and a plurality of driven blocks 25 are respectively provided with through holes, and the through hole of the moving block 18 is set as an internal threaded cylinder 17;

[0066] The first middle block 20 is fixedly connected to the first bracket 21, and the second middle block 24 is fixedly connected to the second bracket 22. The first middle block 20 and the second middle block 24 are respectively fixedly connected to two ends of the same horizontal frame 13;

[0067] Preferably, in this embodiment, the first middle block 20 is integrally fixed at the middle position of the first bracket 21, and the moving blocks 18 are arranged on both sides of the first middle block 20;

[0068] The double-threaded rod 16 passes through the through holes of the first intermediate block 20 and the moving block 18, and the thread of the internal threaded barrel 17 matches the size of the left-hand thread or the right-hand thread on the double-threaded rod 16;

[0069] In this embodiment, the first middle block 20 is disposed at the middle position of the double-threaded rod 16, and the diameter of the through hole of the first middle block 20 is not less than the diameter of the double-threaded rod 16, so as to ensure that the double-threaded rod 16 located inside the first middle block 20 can rotate arbitrarily;

[0070] A plurality of moving blocks 18 are provided on both sides of the first intermediate block 20;

[0071] The rod body of the double-threaded rod 16 located on one side of the first intermediate block 20 is provided with a left-handed thread, and the moving block 18 on the same side is provided with an internal threaded barrel 17 matching the left-handed thread size of the double-threaded rod 16;

[0074] The first intermediate block 20 is equidistantly connected to the moving block 18 via a connecting rod mechanism 19;

[0075] Being connected to the same double-threaded rod 16 ensures that the first intermediate block 20 and the moving block 18 can change the spacing by following the rotation of the double-threaded rod 16 , and the consistency of the spacing change is further ensured by connecting the first intermediate block 20 and the moving block 18 using a connecting rod mechanism 19 .

[0076] The guide rod 23 passes through the through holes of the second intermediate block 24 and the driven block 25;

[0077] Preferably, in this embodiment, the second middle block 24 is integrally fixed at the middle position of the second bracket 22 , and the driven blocks 25 are disposed on both sides of the second middle block 24 ; the driven blocks 25 are integrally slidably sleeved on the guide rod 23 .

[0078] The moving block 18 and the driven block 25 are arranged in pairs, and each pair of the moving block 18 and the driven block 25 is fixedly connected to two ends of a horizontal frame 13 respectively.

[0079] When the double-threaded rod 16 is rotated, the thread structure of the double-threaded rod drives the moving block 18 to adjust the spacing, and the movement of the moving block 18 drives the movement of the cross bar 13, thereby achieving the spacing adjustment between the laser wiring instruments.

[0080] The utility model adjusts the spacing of the laser wiring instrument by combining a connecting rod mechanism with a double threaded rod, and has a simple operation mode and high adjustment efficiency.

[0081] According to an embodiment of the present utility model, the first bracket 21 and the second bracket 22 are both U-shaped structures;

[0082] The two ends of the double threaded rod 16 are respectively connected to the two side plates of the first bracket 21;

[0083] Both ends of the first bracket 21 are provided with fourth rotation holes, and double-threaded rods 16 are rotatably installed inside the two fourth rotation holes;

[0084] The two ends of the guide rod 23 are respectively connected to the two side plates of the second bracket 22;

[0085] Both ends of the second bracket 22 are provided with mounting holes, and guide rods 23 are installed inside the two mounting holes;

[0086] During the process of adjusting the spacing of the laser wiring device 14 , the double-threaded rod 16 and the guide rod 23 are fixed at both ends to avoid lateral displacement of the double-threaded rod 16 and the guide rod 23 .

[0087] The utility model limits and fixes the double-threaded rod and the guide rod, thereby avoiding lateral displacement of the double-threaded rod and the guide rod and increasing the stability of the device.

[0088] According to an embodiment of the present invention, one end of the double-threaded rod 16 is connected to the motor 15 , and the motor 15 is used to control the rotation of the double-threaded rod 16 .

[0089] The utility model adjusts the spacing between the laser wiring instruments 14 by rotating the double-threaded rod 16. Manual adjustment can be achieved by connecting a handle at one end of the double-threaded rod 16, or electric adjustment can be achieved by connecting a motor 15 at one end of the double-threaded rod 16. In this embodiment, the double-threaded rod 16 is adjusted by driving the motor 15, which has higher adjustment efficiency and accuracy.

[0090] Preferably, according to one implementation of this embodiment, the motor 15 uses a servo motor. The servo motor can achieve precise speed and position control and has a better control effect. The servo motor is fixed as a whole on the first bracket 21, and the output shaft of the servo motor is coaxially fixed with the double-threaded rod 16; the double-threaded rod 16 is driven to rotate by the output shaft of the servo motor, and the double-threaded rod 16 respectively causes the moving blocks 18 located on both sides of the first intermediate block 20 to perform opposite linear motions through left-handed threads and right-handed threads. Under the action of the connecting rod mechanism 19, each moving block 18 is synchronously unfolded, and the spacing between two adjacent moving blocks 18 is consistent, that is, each cross frame 13 is equidistantly unfolded, thereby realizing the equidistant adjustment of the distance between each laser wiring instrument 14.

[0092] According to an embodiment of the present invention, the connecting rod mechanism 19 includes a plurality of connecting rod sections, and the center of each connecting rod section is rotatably connected to the top center of the first intermediate block 20 or the top center of the moving block 18 .

[0093] The connecting rod mechanism 19 includes multiple connecting rods of the same length, which are connected end to end and connected in a coaxial manner. Since the first intermediate block 20 and the moving block 18 are the same size, the center of each connecting rod is rotated and connected to the top center of the first intermediate block 20 or the top center of the moving block 18 to ensure the uniformity of the spacing between adjacent cross frames 13.

[0094] Preferably, the middle position of the connecting rod mechanism 19 is rotatably mounted on the first middle block 20 , and the middle positions of the remaining connecting rods are rotatably mounted on the moving blocks 18 .

[0095] The connecting rod mechanism 19 is a prior art and will not be further described here.

[0096] The utility model further ensures the consistency of the spacing change by connecting the first middle block and the moving block through the use of a connecting rod structure.

Both ends of the worm 11 are rotatably installed in the third rotating holes.

[0108] The eccentric handle 9 is rotated to drive the worm 11 to rotate, and the rotation of the worm 11 drives the worm wheel 8 to rotate. Since the worm wheel 8 is coaxially fixedly connected to the rotating shaft 7, the rotating shaft 7 is further driven to rotate.
