DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0023] like Figures 1 to 6 As shown, the utility model provides a bored pile head spacing measuring instrument, including a shell 1, the surface of the shell 1 is evenly provided with scale grooves 2, a rectangular ruler 4 is movably installed inside the shell 1, limiting grooves 3 are provided on both sides of the inside of the shell 1, and limiting blocks 5 located inside the limiting grooves 3 are fixedly installed on both sides of the bottom end of the rectangular ruler 4, scale grooves 7 are evenly provided on the surface of the rectangular ruler 4, and a limiting plate 8 is fixedly installed on the top of the rectangular ruler 4, and the limiting plate 8 is located on the outside of the shell 1.
[0024] When it is necessary to use the spacing measuring instrument to measure the pile head of the bored pile, it is only necessary to place the shell 1 above the ground so that the shell 1 fits the pile head, and then pull the limit plate 8 so that the limit plate 8 drives the rectangular ruler 4 to move upward, pull the limit plate 8 to the top of the bored pile head, and then rotate the fixed plate 10 to the top of the bored pile head, and obtain the data to be measured by calculating the indication of the scale groove 1 2 and the indication of the scale groove 2 7.
[0025] By placing the shell 1 above the ground, pulling the limit plate 8, pulling the limit plate 8 to the top of the bored pile head, rotating the fixing plate 10 to the top of the bored pile head to fix the rectangular ruler 4, the measurement result is obtained. Compared with the traditional bored pile head spacing measuring instrument, this bored pile head spacing measuring instrument places the fixing plate 10 above the bored pile head, so that the shell 1 and the rectangular ruler 4 remain vertical, thereby obtaining a more accurate measurement result.
[0026] Among them, a round block 9 is fixedly installed above the limit plate 8, and a fixed plate 10 is movably sleeved on the outer side of the round block 9. Adjustment grooves 12 are opened on both sides of the limit plate 8. A round rod 13 is fixedly installed inside the adjustment groove 12, and a connecting block 14 is movably sleeved on the outer side of the round rod 13. A vertical plate 15 is fixedly installed on the outer side of the connecting block 14, and a fixed block 17 is fixedly installed above the vertical plate 15. The fixed block 17 is located above the fixed plate 10.
[0027] When it is necessary to rotate the fixing plate 10, first pull the fixing block 17 upwards so that the vertical plate 15 drives the connecting block 14 to move upwards inside the adjusting groove 12, so that the connecting block 14 squeezes the reset spring 16 to deform the reset spring 16, and then rotate the fixing plate 10 to a suitable position, loosen the fixing block 17, and release the elastic potential energy of the reset spring 16 to push the connecting block 14 back to its original position.
[0028] By pulling the fixing block 17, the connecting block 14 moves upward to squeeze the reset spring 16, causing the reset spring 16 to deform, so that the fixing block 17 is separated from the fixing plate 10, and then the fixing plate 10 is rotated to a suitable position. Compared with the traditional cast-in-place pile head spacing measuring instrument, this cast-in-place pile head spacing measuring instrument rotates the fixing plate 10 to a suitable position by pulling the fixing block 17, which is convenient for the use and storage of the fixing plate 10.
[0029] A square hole 11 is formed on the surface of the fixing plate 10 , and the square hole 11 corresponds to the fixing block 17 .
[0030] When the fixing plate 10 is rotated to a suitable position, the fixing block 17 is passed through the square hole 11 to fix the fixing plate 10 .
[0031] A second return spring 16 is elastically installed between the inner side of the adjustment groove 12 and the inner side of the connection block 14 , and the second return spring 16 is movably connected to the outer side of the round rod 13 .
[0032] Pull the fixing block 17 upwards to make the connecting block 14 squeeze the second return spring 16 to deform the second return spring 16, and then rotate the fixing plate 10 to a suitable position.
[0033] The vertical plate 15 is made of rubber, and the fixing blocks 17 are respectively located at two ends of the fixing plate 10 .
[0034] Since rubber is elastic, when the fixing plate 10 needs to be rotated, the fixing block 17 needs to be pulled backward to deform the vertical plate 15. When the fixing plate 10 is rotated to the rightmost end, the vertical plate 15 is pressed upward to deform the vertical plate 15, thereby passing the fixing block 17 through the square hole 11.
[0035] Among them, a return spring 6 is elastically installed between the inner side of the limiting groove 3 and the inner side of the limiting block 5, and the return spring 6 is located inside the limiting groove 3.
[0036] After the measurement is completed, the reset spring 6 releases the elastic potential energy to push the limit block 5 back to its original position, thereby driving the rectangular ruler 4 to be stored inside the housing 1.
[0037] The upper part of the round block 9 is fixedly installed by a fixed round block 18 , and the fixed round block 18 is located above the fixed plate 10 .
[0038] By installing the fixing round block 18 above the round block 9 , the fixing round block 18 limits the fixing plate 10 , thereby preventing the fixing plate 10 from being separated from the round block 9 .
[0039] The working principle and use process of this utility model:
[0040] When it is necessary to use the spacing measuring instrument to measure the pile head of the bored pile, it is only necessary to place the shell 1 above the ground so that the shell 1 fits the pile head, and then pull the limit plate 8 so that the limit plate 8 drives the rectangular ruler 4 to move upward, pull the limit plate 8 to the top of the bored pile head, and then rotate the fixed plate 10 to the top of the bored pile head, and obtain the data to be measured by calculating the indication of the scale groove 1 2 and the indication of the scale groove 2 7.
[0041] When it is necessary to rotate the fixing plate 10, first pull the fixing block 17 upwards so that the vertical plate 15 drives the connecting block 14 to move upwards inside the adjusting groove 12, so that the connecting block 14 squeezes the reset spring 16 to deform the reset spring 16, and then rotate the fixing plate 10 to a suitable position, loosen the fixing block 17, and release the elastic potential energy of the reset spring 16 to push the connecting block 14 back to its original position.
