Description

Technical Field

[0001] The utility model relates to the technical field of pile inclination measurement, in particular to a portable pile inclination measurement device. Background Art

[0002] A pile foundation is composed of a pile and a bearing platform connected to the top of the pile. At present, due to uneven ground, large slopes, the inclination of the pile driver itself, and the non-verticality of the pile during pile stabilization, the pile foundation will incline during the sinking process. If the inclination of the pile foundation is too large, it will affect the bearing capacity of the pile, and even cause the pile foundation to be scrapped, resulting in huge economic losses. In the prior art, two steel bars are inserted into the pile foundation, and then a plumb bob is suspended between the two steel bars to measure the inclination of the pile foundation. This method has the disadvantages of cumbersome operation and inconvenient use. Two steel bars need to be inserted for each pile foundation measurement, which is not convenient for installation and mobile measurement. Content of the Utility Model

[0003] In view of the above prior art, the utility model aims to provide a portable pile inclination measurement device, which can be conveniently installed on the pile foundation for measurement, has simple operation, and can directly observe data.

[0004] To achieve the above object, the technical solution of the embodiment of the utility model is realized as follows:

[0005] A portable pile inclination measurement device includes an upper bottom plate, a plumb line, an L-shaped plate and a clamping assembly. The L-shaped plate is hinged to the upper bottom plate. The upper bottom plate is provided with the plumb line with a plumb bob. The L-shaped plate is provided with scales for observing angles. The upper surface of the upper bottom plate and the lower surface of the L-shaped plate are both fixedly connected with the clamping assembly. The clamping assembly includes a support frame, a spring piece, a first joint plate, a second joint plate, a third joint plate, a clamping plate, a suction cup, a spring and a hydraulic cylinder. The two ends of the spring piece are connected to the support frame. One side of the spring piece is connected with the suction cup, and the other side is connected with the hydraulic cylinder. The first joint plate and the second joint plate are respectively hinged to the support frame. Springs are arranged on both sides of the support frame. One end of each spring is fixed on the support frame, and the other ends are respectively connected to the first joint plate and the second joint plate. The ends of the first joint plate and the second joint plate close to the hydraulic cylinder are both connected to the hydraulic cylinder, and the ends far from the hydraulic cylinder are both connected with the third joint plate. The third joint plate is connected with the clamping plate.

[0006] Furthermore, the upper bottom plate is provided with a wire winding assembly. The wire winding assembly includes a vertical plate, a wire winding wheel and a fixing screw. The vertical plate is installed on the upper bottom plate. The wire winding wheel is rotatably connected to the vertical plate. The plumb line is connected to the wire winding wheel. The vertical plate is provided with the fixing screw.

[0007] Further, the clamping plate includes a bottom connecting plate and a silica gel pad. The silica gel pad is connected to the bottom connecting plate, and the bottom connecting plate is connected to the third joint plate.

[0008] Further, the first joint plate and the second joint plate are respectively provided with fan-shaped plates with waist holes. The waist holes are provided with locking bolts, and the third joint plate is provided with threaded holes that cooperate with the locking bolts. The third joint plate is fixedly connected to the first joint plate and the second joint plate respectively through the fan-shaped plates.

[0009] Further, the suction cup is provided with an exhaust valve.

[0010] Further, the silica gel pad is provided with a plurality of through holes, and steel needles are arranged in the through holes. The steel needles are connected to the bottom connecting plate.

[0011] Further, the L-shaped plate is provided with a guide block.

[0012] Further, the guide block is provided with a guide groove, and the plumb line passes through the guide groove.

[0013] The beneficial effects of the present utility model are as follows: When the hydraulic cylinder works and extends, the first joint plate and the second joint plate connected to one end of the hydraulic cylinder are pushed forward, so that the third joint plate connected to the first joint plate and the second joint plate clamps leans towards the pile foundation around the hinge point, realizing that the clamping plate clamps towards the pile foundation and holds tightly. At the same time, when the hydraulic cylinder extends and pushes the first joint plate and the second joint plate, the reaction force generated causes the elastic piece to deform towards the suction cup, thereby compressing the suction cup, so that the air in the suction cup is squeezed out, making the suction cup suck more firmly. After the installation is completed, just observe the scale aligned by the plumb bob and take the reading, which is convenient for installation on the pile foundation for measurement, with simple operation and intuitive data observation.
