Description

Technical Field

[0001] The utility model relates to the technical field of construction measurement equipment, and more specifically, to a measurement device for breaking the head of a cast-in-place pile. Background Art

[0002] A concrete bored pile is a foundation pile that is made by drilling a hole directly on the site and then pouring concrete into the hole or placing a steel cage and then pouring concrete. According to the different hole-forming methods, it can be divided into bored bored piles, sunken pipe bored piles, manually excavated bored piles, explosive expansion bored piles, etc. Generally speaking, the higher the number of floors of a building, the higher the strength requirements of its foundation structure. Bored piles are widely used in the foundation engineering of high-rise buildings because of their quality, safety and reliability.

[0003] When operators are breaking the pile head of a bored pile, they often use a measuring device to measure the height of the pile head from the ground, so as to calculate the elevation of the pile top after the pile head is broken. In actual use, although the existing measuring devices have basic measuring functions, the existing measuring devices generally require operators to hold them for measurement. When the height of the pile head is much higher than the height of the operator, the measurement becomes more difficult, resulting in a large error in the final measurement data. Therefore, it is necessary to improve them. Utility Model Content

[0025] 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.

[0026] like Figures 1 to 5 As shown, the utility model provides a measuring device for breaking the pile head of a bored pile, comprising:

[0027] A bottom plate 1, the left and right sides of the upper surface of the bottom plate 1 are fixedly connected with support blocks 2, and the upper surface of the support block 2 is movably connected with a movable plate 3;

[0028] A limit rod 8, the limit rod 8 is movably connected to the left and right sides of the upper surface of the movable plate 3, the bottom end of the limit rod 8 sequentially penetrates the movable plate 3 and the support block 2 and extends to the upper surface of the bottom plate 1 and is fixedly connected to the bottom plate 1, and the outer surface of the limit rod 8 and the inner surface of the movable plate 3 are movably sleeved;

[0029] An adjustment mechanism, the adjustment mechanism is arranged on the upper surface of the base plate 1;

[0030] Among them, the adjustment mechanism includes a No. 1 motor 4, which is fixedly installed on the front side of the upper surface of the base plate 1. The other end of the output shaft of the No. 1 motor 4 is fixedly sleeved with a round shaft 5, and the outer surface of the round shaft 5 is fixedly sleeved with a No. 1 connecting rod 6. The other end of the No. 1 connecting rod 6 is hinged to a No. 2 connecting rod 7 located on the front side of the movable plate 3. The other end of the No. 2 connecting rod 7 is hinged to the middle part of the front surface of the movable plate 3. The rotation of the round shaft 5 and the No. 1 connecting rod 6 causes the No. 2 connecting rod 7 to drive the movable plate 3 to move upward as a whole.

[0031] When the No. 1 motor 4 is running, the circular shaft 5 will drive the No. 1 connecting rod 6 to start rotating together. At this time, the No. 2 connecting rod 7 will rotate driven by the other end of the No. 1 connecting rod 6. At the same time, the other end of the No. 2 connecting rod 7 will drive the movable plate 3, so that the movable plate 3 as a whole starts to move upward under the limit of the limit rod 8.

[0032] The middle part of the upper surface of the movable plate 3 is fixedly connected with a support plate 9 , and the upper surface of the support plate 9 is fixedly connected with a connection block 10 .

[0033] The lower surface of the connecting block 10 is the measurement reference of the entire base plate 1. When the lower surface of the connecting block 10 contacts the top of the bored pile, the entire base plate 1 can measure the distance of the pile head from the ground, thereby facilitating the operator to calculate accurate pile top elevation data.

[0034] Among them, a No. 2 motor 11 is fixedly installed on the lower side of the left surface of the support plate 9, and the other end of the output shaft of the No. 2 motor 11 is fixedly sleeved with a mounting shaft 12, the other end of the mounting shaft 12 passes through the support plate 9 and extends to the right side of the support plate 9, the outer surface of the mounting shaft 12 and the inner surface of the support plate 9 are movably sleeved, and the outer surface of the mounting shaft 12 is fixedly sleeved with a take-up wheel 13 located on the inner side of the support plate 9, and the outer surface of the take-up wheel 13 and the inner surface of the support plate 9 are movably connected.

[0035] When the second motor 11 is running, the mounting shaft 12 and the tape reel 13 start to rotate as a whole.

[0036] Among them, a measuring tape 14 is wound around the inner surface of the tape reel 13, the other end of the measuring tape 14 passes through the connecting block 10 and extends to the front side of the lower surface of the connecting block 10 and is fixedly connected to a counterweight block 15 located on the front side of the base plate 1, the outer surface of the measuring tape 14 is movably connected to the inner surface of the connecting block 10, the outer surface of the measuring tape 14 is movably sleeved with a reading block 16 located on the inner side of the support plate 9, and the outer surface of the reading block 16 is fixedly connected to the inner surface of the support plate 9.

[0037] The outer surface of the measuring tape 14 is marked with corresponding length numbers. When the counterweight block 15 contacts the ground, the operator can read the numbers on the outer surface of the measuring tape 14 through the reading block 16 to determine the height from the lower surface of the connecting block 10 to the ground.

[0038] Among them, the front and rear sides of the lower surface of the base plate 1 are fixedly connected with mounting plates 17, the inner surface of the mounting plate 17 is movably sleeved with a rotating shaft 18, the outer surface of the rotating shaft 18 is fixedly sleeved with limit sleeves 26 located on the left and right sides of the mounting plate 17, and the left and right ends of the outer surface of the rotating shaft 18 are fixedly sleeved with moving wheels 19.

[0039] The design of the moving wheels 19 makes it easy for operators to move the base plate 1 as a whole.

[0040] Among them, the left and right sides of the outer surface of the rotating shaft 18 are movably connected with a movable plate 20 located between the movable wheel 19 and the limiting sleeve 26, the number of the movable plates 20 is two, and the outer surfaces of the two movable plates 20 are fixedly connected with brake pads 21 located between the movable wheel 19 and the movable plates 20, and the outer surface of the rotating shaft 18 is movably connected with a spring 22, the outer end of the spring 22 is fixedly connected to the outer surface of the movable plate 20, and the other end of the spring 22 is fixedly connected to the outer surface of the limiting sleeve 26.

[0041] When the two movable plates 20 as a whole begin to move opposite to each other along the outer surface of the rotating shaft 18 and make the brake pad 21 and the movable wheel 19 contact each other, the movable wheel 19 will be unable to rotate due to the friction of the brake pad 21. The design of the spring 22 will make the two movable plates 20 as a whole reset under the elastic force of the spring 22, thereby releasing the contact between the brake pad 21 and the movable wheel 19.

[0042] Among them, a No. 3 motor 23 located below the movable plate 3 is fixedly installed in the middle of the upper surface of the base plate 1, and a rotating shaft 24 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 23. The bottom end of the outer surface of the rotating shaft 24 penetrates the base plate 1 and extends to the bottom of the base plate 1 and is fixedly sleeved with a cam 25. The outer surfaces of the cam 25 are movably connected to the outer surfaces of the two movable plates 20 respectively.

[0043] When the third motor 23 is running, the rotating shaft 24 and the cam 25 will start to rotate, and the rotation of the cam 25 will drive the two moving plates 20 , so that the two moving plates 20 as a whole start to move away from each other along the outer surface of the rotating shaft 18 .

[0044] The working principle and use process of this utility model:

[0045] First, the operator moves the base plate 1 as a whole to the predetermined measuring position, and then starts the No. 3 motor 23. As the No. 3 motor 23 runs, the rotating shaft 24 and the cam 25 begin to rotate. Since the movable plate 20 and the cam 25 are in contact with each other, the two movable plates 20 as a whole will begin to move in opposite directions along the outer surface of the rotating shaft 18 driven by the cam 25. Finally, the overall movement of the two movable plates 20 will cause the brake pad 21 to come into contact with the moving wheel 19. At this time, under the friction force of the brake pad 21, the moving wheel 19 will be unable to rotate, which fixes the base plate 1 as a whole at the measuring position.

[0046] Then the operator starts motor No. 1 4. As motor No. 1 runs, the circular shaft 5 and connecting rod No. 1 6 will rotate, and the other end of connecting rod No. 1 6 will drive connecting rod No. 2 7, so that connecting rod No. 2 7 will start to rotate with the other end of connecting rod No. 1 6 as the axis. At the same time, the other end of connecting rod No. 2 7 will drive the movable plate 3, so that the movable plate 3 as a whole will start to move downward under the limit of the limit rod 8. Finally, when the lower surface of the connecting block 10 contacts the top of the measured pile head, the operator can turn off motor No. 1 4 and start motor No. 2 11.

[0047] As the No. 2 motor 11 runs, the mounting shaft 12 and the take-up wheel 13 will rotate, and the rotation of the take-up wheel 13 will cause the counterweight 15 and the other end of the measuring tape 14 to move downward under the action of gravity. Finally, when the counterweight 15 touches the ground, the operator can read the numbers on the outer surface of the measuring tape 14 through the reading block 16 to obtain the height difference between the top of the pile head and the ground, and use the data to calculate the elevation of the pile top after breaking the pile head, thereby ensuring the performance of the cast-in-place pile and laying a solid and safe foundation for the subsequent construction of the building.
