Description

Technical Field

[0001] This application relates to the field of building construction technology, specifically to a foundation pit measurement device for building engineering supervision. Background Technology

[0002] A building foundation pit is an underground space excavated for the construction of a building's foundation and basement. It is used in building engineering, and the size of the foundation pit varies depending on the size of the building.

[0003] An existing patent (publication number: CN217679307U) discloses a measuring device for excavating foundation pits in building construction, belonging to the field of building construction technology. It includes a reel box: the inner cavity of the reel box is equipped with a line-laying assembly, which includes a rotatable rotating rod located within the reel box cavity. The left end of the rotating rod is rotatably connected to the inner wall of the reel box via a bearing. A rope is wound around the surface of the rotating rod, and a counterweight is attached to the end of the rope furthest from the rotating rod. A base is provided at the bottom of the reel box, and rotatable uprights are provided on both sides of the bottom of the reel box. Limiting components are provided on both sides of the base. This utility model, through the combined use of the uprights and limiting components, installs the reel box and base, and then uses the line-laying assembly to measure the depth of the foundation pit, achieving the goals of convenient use, portability, labor-saving measurement, and accuracy.

[0004] While the device in the aforementioned comparative documents solves the problem that handheld wire laying requires a significant amount of time and effort from workers during the laying and reeling processes, reducing measurement efficiency, the device is bulky, lacks storage functionality, and is inconvenient to carry. Furthermore, the device lacks a leveling mechanism, making it impossible to adjust its levelness according to the actual ground conditions during use. To address these issues, a foundation pit measurement device for construction engineering supervision is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a foundation pit measurement device for construction engineering supervision, which has advantages such as storage function and leveling structure, and solves the problems of bulky structure, inconvenience in carrying, and inability to adjust the levelness of the device according to the actual ground conditions.

[0006] To achieve the above objectives, this application provides the following technical solution: a foundation pit measuring device for construction engineering supervision, comprising a base plate, a fixed cylinder and a spirit level fixedly connected to the top of the base plate, a shrinkage box slidably connected inside the fixed cylinder, a threaded cylinder slidably connected inside the shrinkage box, a connecting block fixedly connected to one end of the threaded cylinder, an electric winding machine fixedly connected to the side of the connecting block, a measuring tape wound inside the electric winding machine, a counterweight cone fixedly connected to the bottom end of the measuring tape, grooves provided on both the front and back of the fixed cylinder, sliders fixedly connected to opposite sides of the shrinkage box, the sliders slidably connected in the grooves, and a placement groove provided on the side of the fixed cylinder; The top four corners of the base plate are fixedly connected with threaded inner cylinders, and the bottom four corners of the base plate are provided with grooves. The threaded inner cylinders are threadedly connected with first bolts, the bottom ends of the first bolts are fixedly connected with support plates, the first bolts are provided with rotating grooves, the first bolts are threadedly connected with second bolts, the bottom ends of the second bolts are fixedly connected with fixed cone tips, the fixed cone tips are located in rotating grooves, and the support plates are located in grooves.

[0007] The above scheme utilizes a fixed cylinder to accommodate the shrink box and provide a sliding track. A sliding groove and slider restrict the shrink box to slide only vertically. A placement slot facilitates horizontal placement of the shrink box during measurement. A bubble level allows for real-time monitoring of the device's horizontal position, ensuring accurate measurement. Rotating the first bolt adjusts the base plate's height to accommodate uneven ground. Rotating the second bolt allows the device to be inserted into soft ground, enhancing its stability.

[0008] Furthermore, the top of the fixed cylinder is provided with shrinkage grooves on both opposite sides, and the top of the shrinkage groove is provided with a through hole.

[0009] The above solution, by setting up shrinkage grooves, provides storage space for connecting springs and positioning blocks.

[0010] Furthermore, a connecting spring is fixedly connected to the inner side of the shrinkage groove, a toggle plate is fixedly connected to one end of the connecting spring, and a positioning block is fixedly connected to the side of the toggle plate.

[0011] The above solution, by setting a toggle plate, a positioning block, and a connecting spring, can stabilize the vertical or horizontal position of the shrink box.

[0012] Furthermore, the actuating plate is slidably connected within the through hole.

[0013] The above solution, by setting through holes, can constrain the movement direction of the toggle plate, ensure that the positioning block extends and retracts along the predetermined trajectory, and avoid structural jamming caused by operational deviation.

[0014] Furthermore, a fixed plate is fixedly connected inside the shrink box, and a rotating rod is tightly nested inside the fixed plate via bearings. A first bevel gear and a threaded rod are fixedly connected to both ends of the rotating rod, and one end of the threaded rod is threaded into a threaded cylinder.

[0015] The above scheme allows the rotation of the rotating rod, the first bevel gear, and the threaded rod to move the threaded cylinder on the surface of the threaded rod, thereby adjusting the position of the electric winding machine to be closer to the center of the pit, making the measurement more accurate.

[0016] Furthermore, a transmission rod is tightly nested inside one of the sliders via a bearing. A knob and a second bevel gear are fixedly connected to both ends of the transmission rod, and the second bevel gear meshes with the first bevel gear.

[0017] Through the above scheme, the rotation of the knob can be converted into the rotation of the rotating rod by the meshing of the first bevel gear and the second bevel gear.

[0018] Furthermore, a limit block is fixedly connected to the surface of the threaded cylinder.

[0019] The above solution, by setting a limit block, can limit the extension and retraction stroke of the threaded cylinder, preventing excessive extension or detachment.

[0020] Furthermore, a handle is fixedly connected to the side of the fixed cylinder.

[0021] The above solution, by incorporating handles, makes it easier for people to carry and move the entire device.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This construction engineering supervision foundation pit measuring device features a fixed cylinder to accommodate a shrink box and provide a sliding track. A sliding groove and slider restrict the shrink box to slide only vertically. A placement groove facilitates horizontal placement of the shrink box during measurement. A spirit level allows for real-time monitoring of the device's horizontal position, ensuring accurate measurement reference. Rotating the first bolt adjusts the base plate's height to adapt to uneven ground. Rotating the second bolt allows the device to be inserted into soft ground, enhancing its stability.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 2 , Figure 3 and Figure 6This embodiment of a foundation pit measurement device for construction engineering supervision includes a base plate 1. A fixed cylinder 101 and a spirit level 1016 are fixedly connected to the top of the base plate 1. A shrinkage box 2 is slidably connected inside the fixed cylinder 101. A threaded cylinder 206 is slidably connected inside the shrinkage box 2. A connecting block 208 is fixedly connected to one end of the threaded cylinder 206. An electric winding machine 3 is fixedly connected to the side of the connecting block 208. A measuring tape 301 is wound inside the electric winding machine 3. A counterweight cone 4 is fixedly connected to the bottom end of the measuring tape 301. The fixed cylinder 101 has grooves 102 on both the front and back. The shrink box 2 is fixedly connected to sliders 201 on both sides. The sliders 201 are slidably connected in the grooves 102. The fixed cylinder 101 has a placement groove 103 on its side. By setting the fixed cylinder 101, the shrink box 2 can be accommodated and a sliding track can be provided. By setting the grooves 102 and sliders 201, the shrink box 2 can be restricted to sliding only in the vertical direction. By setting the placement groove 103, it is convenient for people to place the shrink box 2 horizontally when measuring. Threaded inner cylinders 1010 are fixedly connected to the top four corners of the base plate 1, and grooves 1017 are opened at the bottom four corners of the base plate 1. A first bolt 1011 is threadedly connected inside the threaded inner cylinder 1010. A support plate 1012 is fixedly connected to the bottom end of the first bolt 1011. A rotating groove 1013 is opened inside the first bolt 1011. A second bolt 1014 is threadedly connected inside the first bolt 1011. A fixed cone tip 1015 is fixedly connected to the bottom end of the second bolt 1014. The fixed cone tip 1015 is located in the rotating groove 1013. The support plate 1012 is located in the groove 1017. By setting a bubble level 1016, the horizontal status of the device can be detected in real time to ensure the accuracy of the measurement benchmark. By rotating the first bolt 1011, the horizontal height of the base plate 1 can be adjusted to adapt to uneven ground. By rotating the second bolt 1014, it can be unscrewed and inserted into soft ground to enhance the fixing effect of the device.

[0027] Please see Figure 5 The top of the fixed cylinder 101 has shrinkage grooves 104 on both opposite sides. The top of the shrinkage grooves 104 has through holes 106. By setting the shrinkage grooves 104, storage space can be provided for the connecting spring 105 and the positioning block 108. The connecting spring 105 is fixedly connected to the inner side of the shrinkage groove 104. One end of the connecting spring 105 is fixedly connected to the actuating plate 107. The positioning block 108 is fixedly connected to the side of the actuating plate 107. By setting the actuating plate 107, the positioning block 108 and the connecting spring 105, the vertical or horizontal position of the shrinkage box 2 can be stabilized. The actuating plate 107 is slidably connected in the through hole 106. By setting the through hole 106, the movement direction of the actuating plate 107 can be constrained, ensuring that the positioning block 108 extends and retracts along the predetermined trajectory, and avoiding structural jamming caused by operational deviation.

[0028] Please see Figure 2 and Figure 4 The shrink box 2 has a fixed plate 202 inside, and a rotating rod 203 is tightly nested inside the fixed plate 202 via bearings. A first bevel gear 204 and a threaded rod 205 are fixedly connected to both ends of the rotating rod 203, respectively. One end of the threaded rod 205 is threaded into a threaded cylinder 206. The rotation of the rotating rod 203, the first bevel gear 204, and the threaded rod 205 can move the threaded cylinder 206 on the surface of the threaded rod 205, thereby adjusting the position of the electric winding machine 3 to be closer to the center of the pit for more accurate measurements. A slider 201 has a transmission mechanism tightly nested inside via bearings. The moving rod 209 and the transmission rod 209 are respectively fixedly connected to a knob 2011 and a second bevel gear 2010. The second bevel gear 2010 meshes with the first bevel gear 204. Through the meshing of the first bevel gear 204 and the second bevel gear 2010, the rotation of the knob 2011 can be converted into the rotation of the rotating rod 203. A limit block 207 is fixedly connected to the surface of the threaded cylinder 206. By setting the limit block 207, the extension and retraction stroke of the threaded cylinder 206 can be limited to prevent excessive extension or disengagement. A handle 109 is fixedly connected to the side of the fixed cylinder 101. By setting the handle 109, it is convenient for people to carry and move the entire device.

[0029] In this embodiment, the fixed cylinder 101 can accommodate the shrink box 2 and provide a sliding track. The sliding groove 102 and the slider 201 can restrict the shrink box 2 to slide only in the vertical direction. The placement groove 103 makes it easy for people to place the shrink box 2 horizontally during measurement. The level bubble 1016 can detect the horizontal state of the device in real time to ensure the accuracy of the measurement benchmark. The horizontal height of the base plate 1 can be adjusted by rotating the first bolt 1011 to adapt to uneven ground. The second bolt 1014 can be unscrewed and inserted into soft ground to enhance the fixing effect of the device. The toggle plate 107, the positioning block 108 and the connecting spring 105 can stabilize the vertical or horizontal position of the shrink box 2.

[0030] The working principle of the above embodiment is as follows: When in use, people place the device near the foundation pit, observe the level bubble 1016, rotate the four first bolts 1011, and adjust the position of the four support plates 1012 to adjust the levelness of the device and make the device stable. After placement, people rotate multiple second bolts 1014 to rotate the fixed cone tip 1015 out of the rotating groove 1013 and insert it into the ground. After insertion, the position of the device can be stabilized. After stabilization, people pull multiple actuating plates 107 to move the positioning block 108 into the shrinkage groove 104. After moving in, people lift the shrink box 2 from the fixed cylinder 101 and insert the shrink box 2 into the placement groove 103 to make the shrink box 2 horizontal. After insertion, release the actuating plates 107. Under the action of the connecting spring 105, the two positioning blocks 108 can simply limit the position of the shrink box 2. After being placed horizontally, people rotate knob 2011 to rotate transmission rod 209 and second bevel gear 2010. Through the meshing of first bevel gear 204 and second bevel gear 2010, rotating rod 203 and threaded rod 205 can be driven to rotate. Through the limiting block 207, threaded cylinder 206 can be driven to move on the surface of threaded rod 205, thereby moving the measuring device to the top of the pit. After the movement is completed, electric winding machine 3 is started to release the measuring tape 301. Then, under the action of counterweight cone 4, the position of measuring tape 301 can be made perpendicular to the ground. When the bottom of counterweight cone 4 touches the ground, electric winding machine 3 is stopped. Then, by observing the value of the descent of measuring tape 301, the depth of the pit can be determined.
