Description

Technical Field

[0001] The utility model belongs to the technical field of measuring equipment, and in particular relates to a telescopic bracket for a pendulum line. Background Art

[0002] There are many large workpieces in the hydro-turbine generator that need to be pre-installed on site. Among them, the inner cone and outer cone in the second phase embedded sleeve need to be installed together. The workpiece size is large and the installation is difficult. In addition, the overall height after assembly reaches 6 meters and the maximum diameter is 11 meters. Scaffolding is required during the assembly process, and people have to stand at the top of the workpiece, which poses a great safety hazard. The method for aligning the x-line and y-line of the outer cone is to hang piano wires on the x-line and y-line of the outer cone respectively. The operator wears a safety belt, climbs up the inner cone, and stands on the flange surface to perform alignment operations.

[0003] After the operator holds the lead weight and aligns it with the piano wire, he uses a steel ruler to measure the misalignment between the tip of the weight and the x-line on the inner cone and the x-line on the outer cone. If it exceeds the designed size, the position of the outer cone needs to be adjusted. Repeat the measurement until the technical requirements are met. This method has a great safety hazard, and the efficiency will also be reduced when personnel work at height. Utility Model Content

[0027] Example 2: Based on Example 1, Figure 2For explanation, the rotation limiting assembly 10 includes a ratchet 101, the ratchet 101 is installed on the bobbin 6, a ratchet 102 meshing with the ratchet 101 is rotatably connected to the sleeve frame 3, and a torsion spring is installed between the ratchet 102 and the sleeve frame 3.

[0030] Example 5: Based on Example 1, Figure 3 For explanation, the L frame 4 is rotatably connected with an auxiliary wheel 12 for cooperating with the roller 8 to press the hammer line 13. The present application rotatably connects the auxiliary wheel 12 for cooperating with the roller 8 to press the hammer line 13 on the L frame 4, and presses the hammer line 13 on the roller 8 through the auxiliary wheel 12, so as to prevent the hammer line 13 from being separated from the roller 8 and the hammer line 13 from being worn on the L frame 4 during the process of winding the hammer line 13, thereby facilitating the winding of the hammer line 13, improving work efficiency and extending service life.

[0031] Example 6: Based on Example 1, Figure 4For explanation, the stabilizing component 9 includes a first swivel 911, the first swivel 911 is rotatably connected to the sleeve frame 3, the first swivel 911 is provided with a first concave arc 912, the second swivel 913 for cooperating with the first swivel 911 is rotatably connected to the sleeve frame 3, and the second swivel 913 is provided with a second concave arc 914.

When the distance between the roller 8 and the plumb bob 7 is quickly adjusted, the plumb bob 7 will shake greatly. Then the staff rotates the first rotating ring 911 and the second rotating ring 913 toward the middle, so that the first concave arc 912 and the second concave arc 914 gather the shaking plumb bob 7 toward the middle, so that the shaking amplitude of the plumb bob 7 is quickly reduced, and then the first rotating ring 911 and the second rotating ring 913 are rotated to both sides to separate the first concave arc 912 and the second concave arc 914 from the plumb bob 7, so that the plumb bob 7 automatically returns to a vertical static state, thereby reducing the shaking time of the plumb bob 7, and preventing hand hitting or wire winding incidents caused by manual stabilization of the plumb bob 7, further improving safety and work efficiency.

[0032] Example 7: Based on Example 1, Figure 5 and Figure 6 For explanation, the stabilizing component 9 includes a stabilizing seat 921, the stabilizing seat 921 is slidably connected to the sleeve frame 3, a connecting plate 922 is symmetrically installed on the stabilizing seat 921, a semi-arc sleeve 923 is installed on the connecting plate 922, a gap is set between the two semi-arc sleeves 923 and the hammer line 13, and a second locking knob 924 for limiting the sliding of the stabilizing seat 921 is threadedly connected to the stabilizing seat 921. The present application is that a stabilizing seat 921 is slidably connected to the sleeve frame 3, a connecting plate 922 is symmetrically installed on the stabilizing seat 921, a semi-arc sleeve 923 is installed on the connecting plate 922, a gap is set between the two semi-arc sleeves 923 and the hammer line 13, and a second locking knob 924 for limiting the sliding of the stabilizing seat 921 is threadedly connected to the stabilizing seat 921. When the distance between the roller 8 and the plumb bob 7 is quickly adjusted, after the plumb bob 7 shakes greatly, the staff slides the stabilizing seat 921 downward, so that the stabilizing seat 921 drives the semi-arc sleeve 923 to move downward through the connecting plate 922, and the shaking amplitude of the hammer line 13 is reduced through the semi-arc sleeve 923, and then the stabilizing seat 921 is moved up so that the semi-arc sleeve 923 and the hammer line 13 do not contact each other, so that the plumb bob 7 drives the hammer line 13 to automatically restore to a vertical static state, thereby reducing the shaking time of the plumb bob 7 and further improving safety and work efficiency.

[0033] Embodiment 8: Based on Embodiment 1, Figure 7To explain, the stabilizing component 9 includes a sliding sleeve 931, the sleeve frame 3 is slidably connected with the sliding sleeve 931, a connecting rod 932 is installed on the sliding sleeve 931, and a stabilizing funnel 933 is installed on the connecting rod 932. In the present application, the sliding sleeve 931 is slidably connected with the sleeve frame 3, the connecting rod 932 is installed on the sliding sleeve 931, and the stabilizing funnel 933 is installed on the connecting rod 932. When the distance between the roller 8 and the plumb bob 7 is quickly adjusted, the plumb bob 7 shakes greatly. Then the staff moves the sliding sleeve 931 upward, so that the sliding sleeve 931 drives the stabilizing funnel 933 upward through the connecting rod 932, and uses the opening above the stabilizing funnel 933 to contact the shaking plumb bob 7, so as to quickly reduce the shaking amplitude of the plumb bob 7. Then the sliding sleeve 931 moves down and returns to the starting position, so that the plumb bob 7 automatically returns to a vertical static state, thereby reducing the shaking time of the plumb bob 7 and further improving safety and work efficiency.

[0034] Working process:

[0035] When adjusting the measuring height of the plumb bob 7, the distance between the roller 8 and the base 1 can be changed by sliding the L frame 4 up and down, and then the L frame 4 is locked using the first locking knob 5. The staff then rotates the ratchet 102 using the butterfly knob 103 to separate the ratchet 102 from the ratchet 101, and the staff rotates the spool 6 using the handle 11 to release or reel in the plumb line 13. After the staff releases the butterfly knob 103, the ratchet 102 engages with the ratchet 101 to prevent the spool 6 from rotating clockwise, and the staff completes the adjustment of the measuring height of the plumb bob 7 on the ground.
