Description

Technical Field

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavating the foundation pit, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage should be done well; during the excavation of the foundation pit, the depth, width and slope of the excavation of the foundation pit need to be monitored in real time to ensure that the excavated foundation pit data is consistent with the data calculated in advance in the plan.

[0003] The existing foundation pit excavation and measuring device includes a base, a propulsion frame is slidably connected to the top of the base, the middle push plate is movably connected between the base and the propulsion frame, and the rotating guide plate is connected to the right end of the propulsion frame by a hinge. It has a supporting mounting frame for adjusting the measuring mechanism. The measuring ruler is located inside the foundation pit through telescopic drive, and the inclination of the measuring ruler is recorded and corrected through the angle disk, thereby improving the verticality of the measuring ruler and measuring the foundation pit data more accurately.

[0004] Although the existing device can improve the accuracy of foundation pit measurement data by correcting the verticality of the measuring ruler, the existing device can only measure a single point position of the foundation pit at a time. Since the foundation pit is mainly excavated by excavation tools, the depth of each position cannot be kept consistent. Therefore, it is necessary to perform multi-point measurement of the foundation pit to improve the accuracy of the measurement data. Due to the complexity of the construction environment, it is not possible to use multiple existing devices to measure multiple positions of the foundation pit at the same time.

[0047] The measuring structure includes a measuring component A8 and a measuring component B10. One end of the measuring component A8 is fixed on the connecting bottom plate 7 and slidably cooperates with the outer wall of the square guide column 2. The other end of the measuring component A8 is installed on the fixing frame 3. The measuring components B10 surround the center of the connecting bottom plate 7 and are circumferentially distributed on the outer side thereof.

[0048] The stretching structure 9 includes a U-shaped plate 91, a control component 92, a stretching component 93 and a mounting member 94. The U-shaped plate 91 is distributed on the connecting frame 5. The mounting member 94 is mounted on the U-shaped plate 91. The control component 92 connected to the fixing frame 3 is mounted on the mounting member 94.

[0049] The control assembly 92 includes a rack A921, a gear A922, a gear B923 and a rack B924. The rack A921 is circumferentially distributed on the fixed frame 3. The rack A921 is meshed with a gear A922 rotatably mounted on the mounting member 94. The gear B923 is rotatably mounted on the mounting member 94 and is coaxial with the gear A922. One side of the gear B923 is meshed with a rack B924. The rack B924 is vertically slidably mounted on the mounting member 94. One side of the rack B924 is connected to the control assembly 92 arranged on the outside thereof. The control assembly 92 is circumferentially distributed above the connecting base plate 7 and is connected to the connecting base plate 7. The measuring assembly B10 is mounted on the outside of the control assembly 92.

[0051] When the T-shaped connecting plate 1 moves to the top of the foundation pit, the measuring structure and the stretching structure 9 both move to the top of the foundation pit, the telescopic hydraulic component 4 drives the connecting frame 5 to move toward the direction close to the foundation pit, and the connecting frame 5 drives the sliding frame 6 and the U-shaped plate 91 to move toward the direction close to the foundation pit at the same time, the U-shaped plate 91 drives the mounting member 94 to move toward the direction close to the foundation pit, and the sliding frame 6 drives the connecting bottom plate 7 to move toward the direction close to the foundation pit, and the connecting bottom plate 7 can drive the gear A922, the gear B923, the rack B924 and the stretching component 93 to move toward the direction close to the foundation pit by cooperating with the mounting member 94. At the same time, the connecting bottom plate 7 drives one end of the measuring component A8 to move, and the measuring component A8 can measure the downward travel of the connecting bottom plate 7 and obtain corresponding measurement data by moving one end and cooperating with the fixing frame 3;

[0052] Since the position of rack A921 is fixed, gear A922 rotates simultaneously during the movement, gear A922 drives gear B923 to rotate, gear B923 drives rack B924 to move toward the direction close to the foundation pit, and rack B924 drives the extension component 93 to work. The multi-group controlled extension component 93 can simultaneously drive the multi-group measuring component B10 to expand in the direction away from the square guide column 2 while maintaining the vertical state unchanged, so that the multi-group measuring component B10 can measure multiple positions in the foundation pit at the same time and obtain corresponding measurement data, which can complete the measurement work of the foundation pit in a short time, speed up the measurement efficiency of the foundation pit, and improve the accuracy of the measurement data. Automated measurement reduces the need for personnel to work directly at the edge of the foundation pit, thereby reducing safety risks in work.

[0053] like Figures 1 to 6 As shown, as a preferred embodiment of the present invention, the square guide column 2, rack A921, rack B924, extension component 93 and measuring component B10 are all parallel to each other, so that the measuring component B10 can accurately measure the excavation depth of the foundation pit, and the diameters of the gear A922 and the gear B923 can be consistent or inconsistent. When the diameter of the gear B923 is larger than the diameter of the gear A922 and the size and distribution spacing of the gear teeth on the two are consistent, the rack B924 can be driven to move downward quickly at a speed faster than the speed of the connecting base plate 7, thereby accelerating the extension efficiency of the extension component 93, so that the measuring component B10 can quickly reach the required measurement position, thereby improving the measurement efficiency of the foundation pit.

[0054] like Figures 1 to 6As shown, as a preferred embodiment of the present invention, the mounting member 94 preferably adopts a mounting structure composed of a U-shaped clamp and a strip rod. The U-shaped clamp is installed inside the U-shaped plate 91 by fixing screws, and the strip rod is fixed on one side of the U-shaped clamp. A rack B924 is slidably installed on the strip rod, and gears A922 and gear B923 are rotatably installed on the U-shaped clamp.

[0055] like Figures 1 to 6 As shown, as a preferred embodiment of the present invention, the extension component 93 includes a first connecting rod 931, a second connecting rod 932, a hinge seat 933 and an extension seat 934, one end of the first connecting rod 931 is rotatably connected to one side of the rack B924 through the hinge seat 933, the other end of the first connecting rod 931 is rotatably connected to one end of the extension seat 934, one end of the second connecting rod 932 is rotatably mounted on the connecting base plate 7 through the hinge seat 933, the other end of the second connecting rod 932 is rotatably connected to the other end of the extension seat 934, and the first connecting rod 931 and the second connecting rod 932 are rotatably connected to each other.

[0056] like Figures 1 to 6 As shown, as a preferred embodiment of the present invention, the first connecting rod 931 and the second connecting rod 932 have the same length, the two hinge seats 933 are on the same vertical plane, and the extension seat 934 and the rack B924 are parallel to each other.

[0057] In this embodiment, when the rack B924 moves toward the direction approaching the foundation pit, the rack B924 drives one end of the first connecting rod 931 to move through an articulated seat 933, so that the first connecting rod 931 can rotate. At the same time, since the other articulated seat 933 is stationary relative to the connecting base plate 7, and the first connecting rod 931 and the second connecting rod 932 are rotatably connected to each other, the second connecting rod 932 can also rotate. The first connecting rod 931 and the second connecting rod 932 can drive the extension seat 934 to move outward in a manner of maintaining a vertical state by rotating together, so that multiple groups of measuring components B10 can simultaneously measure multiple positions in the foundation pit and obtain corresponding measurement data, so as to complete the measurement of the foundation pit in a short time, speed up the measurement efficiency of the foundation pit, and improve the accuracy of the measurement data.

[0058] like Figures 1 to 5 As shown, as a preferred embodiment of the present invention, the measuring component A8 includes a scale plate 81 and a monitoring probe A82, one end of the scale plate 81 is fixed on the connecting base plate 7, the other end of the scale plate 81 is slidably mounted on the outer wall of the square guide column 2, the monitoring probe A82 is fixed on the fixing frame 3, the monitoring probe A82 is electrically connected to the control center, the control center is installed on the mobile device, the monitoring probe A82 faces the scale plate 81, and its monitoring end is perpendicular to the scale plate 81.

[0059] In this embodiment, when measuring the depth of the foundation pit, the monitoring end of the monitoring probe A82 is first moved to a position flush with the top of the foundation pit, thereby setting this place as the measurement reference point. When the connecting bottom plate 7 moves toward the direction close to the foundation pit, the connecting bottom plate 7 drives the scale plate 81 to descend, and the monitoring probe A82 monitors the downward movement of the scale plate 81 in real time, and transmits the data of the descending height of the scale plate 81 back to the control center, so that the staff at the control center can quickly obtain the corresponding data, which is set to X.

[0060] like Figures 1 to 6 As shown, as a preferred embodiment of the present invention, the measuring component B10 includes a reference block 101, a scale rod 102, a restoring spring 103, a U-shaped fixed block 104, a U-shaped sliding block 105 and a monitoring probe B106, the U-shaped fixed block 104 is fixed on the other side of the extension seat 934, the U-shaped sliding block 105 is slidably installed on the extension seat 934, the scale rod 102 is fixed to the bottom of the U-shaped sliding block 105, one end of the scale rod 102 passes through the U-shaped fixed block 104 and is fixedly connected to the reference block 101, a restoring spring 103 is installed between the reference block 101 and the U-shaped fixed block 104, a monitoring probe B106 is fixed on the U-shaped fixed block 104, the monitoring probe B106 is electrically connected to the control center, the monitoring probe B106 faces the scale rod 102, and its monitoring end is perpendicular to the scale rod 102.

[0061] In this embodiment, the extension seat 934 drives the measuring assembly B10 to move toward the foundation pit, and also drives it to expand in the foundation pit in a manner of maintaining a vertical state. When the reference block 101 moves down to contact the bottom wall of the foundation pit, the U-shaped fixed block 104 continues to move down, so that the reference block 101 drives the U-shaped sliding block 105 to slide on the extension seat 934 through the scale rod 102, and at the same time, the restoring spring 103 is in a squeezed state;

[0062] During this process, the scale rod 102 moves vertically relative to the U-shaped fixed block 104 in a direction away from the foundation pit. The monitoring probe B106 can monitor the upward movement data of the scale rod 102 in real time and transmit the upward movement data of the scale rod 102 back to the control center, and this data is set as Y;

[0063] In the initial state, the restoring spring 103 drives the reference block 101 to return to the initial position through its own elastic force, so that the scale rod 102 also returns to the initial state. At the same time, the connecting bottom plate 7 and the scale plate 81 are both in the initial position. At this time, the vertical height data from the monitoring probe A82 to the monitoring end to the reference block 101 is set to Z, and the excavation depth D of the foundation pit can be calculated by the following formula:

[0064] D=X+ZY.

[0065] like Figure 2 , Figure 3 , Figure 4 Figure 7 As shown, as a preferred embodiment of the present invention, a connecting pipe 11 is fixed to the bottom of the T-shaped connecting plate 1, and the connecting pipe 11 extends to the inside of the square guide column 2, and the connecting pipe 11 and the square guide column 2 are respectively provided with through holes for bolts 12 to pass through, and the bolts 12 can connect the connecting pipe 11 and the square guide column 2 as a whole by passing through the through holes on both, and then connect the square guide column 2 and the T-shaped connecting plate 1 as a whole;

[0066] The set number of bolts 12 can be freely selected according to actual conditions, and multiple bolts 12 connect the connecting pipe 11 and the square guide column 2 as a whole in a mutually perpendicular manner, which can improve the connection stability between the two, thereby ensuring the accuracy of the measurement data and improving the working efficiency and practicality of the device.

[0067] The working principle of the present invention is:

[0068] When the T-shaped connecting plate 1 moves to the top of the foundation pit, the measuring structure and the stretching structure 9 both move to the top of the foundation pit. Before measuring the depth of the foundation pit, the monitoring end of the monitoring probe A82 is first moved to a position flush with the top of the foundation pit, so that this place is set as the measurement reference point. The telescopic hydraulic component 4 drives the connecting frame 5 to move toward the direction close to the foundation pit, and the connecting frame 5 drives the sliding frame 6 and the U-shaped plate 91 to move toward the direction close to the foundation pit. The U-shaped plate 91 drives the mounting component 94 to move toward the direction close to the foundation pit, and the sliding frame 6 drives the connecting frame 5 to move toward the direction close to the foundation pit. The connecting bottom plate 7 moves toward the direction close to the foundation pit. The connecting bottom plate 7 can drive the gear A922, the gear B923, the rack B924 and the extension component 93 to move toward the direction close to the foundation pit by cooperating with the mounting member 94. The extension component 93 drives the measuring component B10 thereon to move. At the same time, the connecting bottom plate 7 drives one end of the measuring component A8 to move. The measuring component A8 can measure the downward movement stroke of the connecting bottom plate 7 and obtain corresponding measurement data by moving one end and cooperating with the fixing frame 3.

[0069] Since the position of the rack A921 is fixed, the gear A922 rotates at the same time during the movement, the gear A922 drives the gear B923 to rotate, the gear B923 drives the rack B924 to move in the direction close to the foundation pit, and the rack B924 drives one end of the first connecting rod 931 to move through an articulated seat 933, so that the first connecting rod 931 can rotate, and at the same time, since the other articulated seat 933 is stationary relative to the connecting bottom plate 7, and the first connecting rod 931 and the second connecting rod 932 are rotatably connected to each other, the second connecting rod 932 can also rotate, and the first connecting rod 931 and the second connecting rod 932 can drive the extension seat 934 to move outward in a manner that remains unchanged after the vertical state is maintained by rotating together;

[0070] When the connecting bottom plate 7 moves toward the direction close to the foundation pit, the connecting bottom plate 7 drives the scale plate 81 to descend, and the monitoring probe A82 monitors the downward movement of the scale plate 81 in real time, and transmits the data of the descending height of the scale plate 81 back to the control center, so that the staff at the control center can quickly obtain the corresponding data, which is set as X;

[0071] The extension seat 934 drives the measuring assembly B10 to move toward the foundation pit, and also drives it to expand in the foundation pit in a manner of maintaining a vertical state. When the reference block 101 moves down to contact the bottom wall of the foundation pit, the U-shaped fixed block 104 continues to move down, so that the reference block 101 drives the U-shaped sliding block 105 to slide on the extension seat 934 through the scale rod 102, and at the same time, the restoring spring 103 is in a squeezed state;

[0072] During this process, the scale rod 102 moves vertically relative to the U-shaped fixed block 104 in a direction away from the foundation pit. The monitoring probe B106 can monitor the upward movement data of the scale rod 102 in real time and transmit the upward movement data of the scale rod 102 back to the control center, and this data is set as Y;

[0073] In the initial state, the restoring spring 103 drives the reference block 101 to return to the initial position through its own elastic force, so that the scale rod 102 also returns to the initial state. At the same time, the connecting bottom plate 7 and the scale plate 81 are both in the initial position. At this time, the vertical height data from the monitoring probe A82 to the monitoring end to the reference block 101 is set to Z, and the excavation depth D of the foundation pit can be calculated by the following formula:

[0074] D = X + ZY;

[0075] By setting up multiple groups of measurement components B10, different points in the foundation pit can be measured simultaneously, so that different data Y can be obtained. By using the above formula, the excavation depth of the foundation pit at different points can be obtained at the same time, thereby achieving effective measurement of the foundation pit and rapid measurement of the foundation pit, thereby improving the accuracy of the foundation pit excavation depth data;

[0076] The above is the working principle of the earthwork foundation pit excavation and measuring device for building construction.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
