[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0024] The present invention provides a municipal pipeline joint fixing auxiliary device, see Figure 1 , including: two supporting and fixing components 100, a supporting cross bar 200 and a measuring component 300; the two supporting and fixing components 100 are slidably installed at both ends of the supporting cross bar 200; and the measuring component 300 is detachably installed on the supporting cross bar 200.

[0025] In this design, the support crossbar 200 is supported by two support fixing components 100, and the support fixing components 100 can be adjusted to adapt to different pipes. The required data can be obtained by using a measuring instrument for real-time measurement. It has the advantages of fast disassembly and assembly speed, continuous installation, convenient movement, simple production and low cost, economical and practical, shortening the construction period, and improving economic benefits.

[0026] In this embodiment, see Figure 1-Figure 2 The support and fixing assembly 100 includes: a support frame 110, a connecting sleeve 120 and two fixing members 130; the support frame 110 is installed on the support cross bar 200 through the connecting sleeve 120; and the two fixing members 130 are symmetrically installed at both ends of the support frame 110.

[0027] Exemplarily, the support plate is in an inverted "U" shape.

[0028] In this embodiment, see Figure 1-Figure 3 The fixing member 130 includes a supporting transverse plate 131, a supporting vertical plate 132, a locking bolt 133, a screw 134 and a positioning plate 135; one end of the supporting transverse plate 131 is fixed to the supporting frame 110, and the supporting vertical plate 132 is slidably mounted on the supporting transverse plate 131 through the connecting sleeve 120; the screw 134 is mounted at the bottom end of the supporting vertical plate 132, and the positioning plate 135 is mounted at one end of the screw 134.

[0029] Exemplarily, a flexible rubber pad 136 is provided on one side of the positioning plate 135 .

[0030] In this embodiment, see Figure 1-Figure 3 The supporting horizontal plate 131 and the supporting vertical plate 132 are both provided with scales.

[0031] With this design, the support horizontal plate 131 and the support vertical plate 132 are both provided with scales, and accurate positioning and adjustment can be performed through the locking bolts 133 on both sides of the connecting sleeve 120. Loosening the locking bolts 133 on the side of the support horizontal plate 131 allows the support vertical plate 132 to move in the horizontal direction of the support horizontal plate 131, and according to the scale on the support horizontal plate 131, it is precisely adjusted to move to a suitable position and then tighten the locking bolts 133 to lock it firmly. Loosening the locking bolts 133 on the side of the support vertical plate 132 allows the support vertical plate 132 to move in the vertical direction, and according to the scale on the support vertical plate 132, the positioning plate 135 is precisely adjusted to move to a suitable height and then tighten the locking bolts 133 to lock it firmly.

[0032] Exemplarily, a limiting block 137 is provided on the top of the supporting vertical plate 132 .

[0033] Exemplarily, a limiting nut 138 is provided at one end of the supporting cross plate 131 .

[0034] In this embodiment, see Figure 1-Figure 3 The bottom end of the support vertical plate 132 is provided with a threaded sleeve 139, the screw rod 134 passes through the threaded sleeve 139, and the end of the screw rod 134 is connected to the positioning plate 135. One end of the screw rod 134 is provided with a handle 140.

[0035] With this design, the position of the positioning plate 135 can be fine-tuned by rotating the handle 140 so that it fits closely with the pipe diameter.

[0036] In this embodiment, a guide rod 141 is further provided at the lower end of the threaded sleeve 139 , and the end of the guide rod 141 is fixedly connected to the positioning plate 135 by bolts.

[0037] With this design, the positioning plate 135 is fixed by bolts alone, and the stability of the positioning plate 135 is poor, and it is easy to flip and loosen. A guide rod 141 is also provided at the lower end of the threaded sleeve 139. The end of the guide rod 141 is fixedly connected to the positioning plate 135 by bolts, which can solve the problem of flipping and loosening of the positioning plate 135. By adjusting the guide rod 141, the inclination angle of the positioning plate 135 can be adjusted to make it fit closely with the pipe diameter. The positioning plate 135 is covered with a layer of flexible rubber pad 136, which can increase the friction with the pipe wall, increase the fit, and enhance stability.

[0038] In this embodiment, the connecting sleeve 120 fixes the support frame 110 by means of fixing bolts 150 .

[0039] In this embodiment, see Figure 1-Figure 5 The measuring assembly 300 includes a laser rangefinder 310 and a target plate 320; the laser rangefinder 310 is fixed on the supporting crossbar 200, and the target plate 320 is installed on the fixing bolt 150 at the other end of the crossbar.

[0040] Exemplarily, a rotating bolt 330 is provided above the fixing bolt 150, and the rotating bolt 330 is fixed together with the target plate 320. When the supporting fixing assembly 100 is adjusted to a suitable position on the cross bar, it can be fixed by the fixing bolt 150. After fixing, the rotating bolt 330 is rotated to adjust the angle of the target plate 320 so that its target surface is aligned with the laser rangefinder 310.

[0041] In this embodiment, see Figure 1-Figure 5 The measuring assembly 300 further includes a slope measuring device 340, which is fixed on the crossbar.

[0042] The slope measuring device 340 is mainly composed of a dial 341, a rotating disk 342, and a horizontal bubble tube 343 fixed at the center of the rotating disk 342. After the device is fixed on the crossbar, the rotating disk 342 is manually rotated, and the horizontal bubble tube 343 will rotate together until the horizontal bubble in the middle of the rotating disk 342 is adjusted to the central horizontal position. At this time, the position of the dial 341 pointed by the pointer on the rotating disk 342 is the angle between the pipeline and the horizontal plane, and the actual slope of the pipe section can be known.

[0043] Exemplarily, two "⊥"-shaped clamping strips are provided at the bottom of the installation plate of the slope measuring device 340, and two "⨆" clamping slots matching the clamping strips are provided on the end surface of the crossbar. The upper ends of the two vertical clamping strips of each "⨆" clamping slot are concave, and the bottom of the installation plate of the slope measuring device 340 can be closely attached to the upper surface of the crossbar, and the end of the "⊥"-shaped clamping strip is aligned with the end of the clamping slot on the end surface of the crossbar. The "⊥"-shaped clamping strip is plugged into the "⨆" clamping slot by moving the slope measuring device 340, and the locking bolt 133 on one side of the handle is turned to fix it. The square plugging rod at the bottom of the laser rangefinder 310 can be installed in the slot above the slope measuring device 340.

[0044] The assembly method of this device is as follows: The first step: stand the support frame 110 of the first support and fixing assembly 100 upright, connect the end of the cross bar connected to the support and fixing assembly 100 through the connecting sleeve 120 in the middle of the crossbeam of the support frame 110, rotate and tighten the fixing bolt 150 to fix it, then stand the support frame 110 of the second support and fixing assembly 100 upright, and connect and fix it to the support frame 110 in the same way.

[0045] Step 2: Install the slope measuring device 340 and the laser rangefinder 310. After the support frame 110 of the second support fixing assembly 100 is installed, the rotating bolt 330 on the fixing bolt 150 of the middle connecting sleeve 120 of the crossbeam of the rotating support frame 110 is rotated, and the target plate 320 and the rotating bolt 330 are integrally formed. The angle of the target plate 320 can be adjusted by rotating the rotating bolt 330, and the panel can be aligned with the direction of the laser rangefinder 310.

[0046] Step 3: Unscrew the limit bolt at the end of the support horizontal plate 131 of the support frame 110, and insert the connecting sleeve 120 of the support vertical plate 132 from the end of the support horizontal plate 131, adjust it to a suitable scale, and then tighten it by turning the locking bolt 133. All four fixing components are installed and fixed in this way.

[0047] Step 4: Rotate the screw rod 134 on the handle 140 through the threaded sleeve 139 at the bottom end of the support vertical plate 132, align it with the bolt hole on the back of the positioning plate 135, tighten it, and turn the handle 140 to adjust it to a suitable distance. The end guide rod 141 is also installed in this way.

[0048] Auxiliary joint fixing construction method: First, place the first support fixing assembly 100 at the appropriate position of the pipe section, adjust the locking bolt 133 on the connecting sleeve 120 of the support cross plate 131 according to the pipe diameter, move the fixing assembly to the appropriate position, lock and fix it, then turn the handle 140 and the guide rod 141, adjust the distance and angle of the positioning plate 135 to make it fit tightly. Then loosen the fixing bolt 150 on the middle connecting sleeve 120 of the crossbeam of the second support fixing assembly 100 support frame 110, move the second support fixing assembly 100 to the appropriate position according to the actual length of the pipe section, tighten the fixing bolt 150, and lock it. Then adjust the locking bolt 133 on the connecting sleeve 120 of the support cross plate 131 according to the pipe diameter, move the fixing assembly to the appropriate position, lock and fix it, then turn the handle 140 and the guide rod 141, adjust the distance and angle of the positioning plate 135 to make it fit tightly. This setting can solve the problems of uneven force on pipe sections during the butt installation process, inability to align the interfaces, up and down and left and right shaking, poor stability, and difficulty in butt installation, greatly improving safety and stability and improving construction efficiency.

[0049] Slope measurement construction method: After the slope measuring device 340 is fixed, a horizontal bubble tube 343 is fixed at the center of the rotating disk 342. The rotating disk 342 is manually rotated until the horizontal bubble in the middle of the rotating disk 342 is adjusted to a horizontal position. At this time, the position of the scale plate 341 pointed by the pointer on the rotating disk 342 is the angle α between the pipeline and the horizontal plane, and the actual slope of the pipe section i=tanα can be known. At the same time, scales are set on the supporting horizontal plate 131 and the supporting vertical plate 132 of the device. By adjusting the scales of the supporting plates of the two supporting fixing components 100, the straightness of the pipe section can be adjusted to make its positioning consistent. This setting can solve the problem that the existing pipe section auxiliary installation device cannot more accurately position and adjust the pipeline.

[0050] Construction method for adjusting the width and length of the device: This device uses two supporting and fixing components 100. The second supporting and fixing component 100 can be moved arbitrarily on the crossbar of the support frame 110, and is fixed by tightening the fixing bolts 150 under the target plate 320, so that the length of the device itself can be adjusted over a wide range to match pipes of different lengths (the adjustment range depends on the length of the crossbar). At the same time, by adjusting the position of the connecting sleeve 120 on the support frame 110 of the two supporting and fixing components 100, the distance between the two positioning plates 135 of the same supporting and fixing component 100 can be adjusted over a wide range, thereby adjusting the width of the device itself over a wide range to match pipes of different diameters (the adjustment range depends on the length of the supporting cross plates 131 on both sides). This setting can solve the problem that the existing pipeline auxiliary device cannot adjust the length and width of the device itself over a wide range to match different pipe diameters, and cannot adapt to the use requirements of various groove angles and groove widths.

[0051] Continuous installation construction method: The slope measuring device 340 of the device is provided with a handle (installed integrally with the slope measuring device 340). When the pipe section under construction is installed, there is no need to disassemble the device. The device can be reinstalled at the installation position of the next pipe section. Only the four locking bolts 133 need to be loosened and the handle can be moved to the joint of the next pipe section. This setting can solve the problem that some existing pipeline installation auxiliary devices are installed for a certain pipe section. After the pipe section is installed, the device needs to be disassembled again, and continuous installation construction cannot be performed.

[0052] Construction method for measuring pipe height difference, horizontal distance, buried depth, elevation and other data: The slope measuring device 340 of the device close to the first supporting and fixing assembly 100 is provided with a laser rangefinder 310, and the second supporting and fixing assembly 100 is provided with a target plate 320. Rotate the target plate 320, after the support frame 110 of the second supporting and fixing assembly 100 is installed, rotate the rotating bolt 330 on the fixing bolt 150 of the middle connecting sleeve 120 of the crossbeam of the rotating support frame 110, and the target plate 320 and the rotating bolt 330 are integrally formed. Rotate the rotating bolt 330 to adjust the angle of the target plate 320, align the panel with the direction of the laser rangefinder 310, and turn on the laser rangefinder 310 to measure the distance l between the two supporting and fixing assemblies 100. The angle α between the pipe section and the horizontal plane can be known through the slope measuring device 340, so that the height difference h=lcosα at both ends of the pipe section and the horizontal distance x=lsinα at both ends of the pipe section can be known. Then, combined with the known elevation data, the elevation and burial depth of a certain part of the pipeline can be inferred. This setting can solve the problem that some existing pipeline installation auxiliary devices generally require the cooperation of surveyors and obtain the required data by using measuring instruments for real-time measurement.
