Description

Technical Field

[0001] The utility model relates to the field of foundation pit data collection, in particular to a real-time data collection and sensing device for a deep foundation pit. Background Art

[0002] Existing Chinese patent: Deep foundation pit monitoring device (CN214614240U), the device is connected to the plumb bob by a hanging rope, the prism is rotatably connected to the support frame, and a weight is fixedly connected to the prism, which can make the prism in a vertical state. The prism height measured by the total station and the height difference between the prism and the plumb bob can accurately reflect the deformation of the pit bottom of the foundation pit, so as to avoid the problem that the ground uplift at the bottom of the foundation pit may cause the tilt of the lifting device and the prism, so that the position change of the prism cannot accurately reflect the uplift deformation of the pit bottom of the foundation pit;

[0003] However, the prism of the device is rotatably connected to the support frame, and the bulge deformation of the pit bottom is uncertain. If the prism can be rotated in the front and back directions, that is, the prism cannot be rotated to the left and right, then when the main body of the device tilts to the left and right, the prism will also tilt, and it is impossible to ensure that the prism will always be in a vertical state when the main body of the device tilts, which is likely to cause errors in the data measured by the total station;

[0004] Moreover, when the main body of the device tilts away from the plumb bob, the device will pull the plumb bob to move through the hanging rope, so the plumb bob will tilt or not be at the test point. That is, when this happens, it is also easy to cause errors in the data measured by the total station. Utility Model Content

[0005] In order to overcome the disadvantage that since the prism is rotatably connected to the support frame, if the prism can be rotated to the front and back, that is, the prism cannot be rotated to the left and right, it cannot be guaranteed that the prism will always be in a vertical state when the main body of the device is tilted, the utility model provides a deep foundation pit real-time data collection and sensing device.

[0006] The technical solution is: a real-time data acquisition and sensing device for a deep foundation pit, comprising a seat plate, a mounting frame, a support plate, a mounting plate and an electric push rod; the seat plate is fixedly connected to the mounting frame; the mounting frame is slidably connected to the support plate; the support plate is fixedly connected to the mounting plate; the seat plate is fixedly connected to an electric push rod, and the telescopic portion of the electric push rod is fixedly connected to the mounting plate; it also includes a gantry, a mounting block, a rotating ball, a prism, a counterweight, a plumb bob and an adjustment assembly; the mounting plate is fixedly connected to the gantry; the gantry is fixedly connected to the mounting block; the mounting block is connected to a rotating ball through a universal shaft; the rotating ball is fixedly connected to a prism; the rotating ball is used to enable the prism to rotate in any direction forward, backward, left or right; the prism is fixedly connected to a counterweight; the mounting plate is connected to an adjustment assembly; the adjustment assembly is connected to a plumb bob; the adjustment assembly is used to adjust the position of the plumb bob.

[0007] As a further preferred scheme, the adjustment component includes two electric push rods, two mounting blocks, two rotating balls, one long rod, two long rods and a fixed rod; the mounting plate is fixedly connected to the two electric push rods; the telescopic part of the two electric push rods is fixedly connected to the two mounting blocks; the two mounting blocks are connected to the two rotating balls through a universal joint; the two rotating balls are fixedly connected to the one long rod; the one long rod is slidably connected to the two long rods, and the two long rods are connected to the plumb bob; the one long rod is screwed to the fixed rod, and the fixed rod is in contact with the two long rods.

[0008] As a further preferred solution, the adjustment component also includes rotating ball three; the long rod two is connected to the rotating ball three through a universal shaft, and the rotating ball three is fixedly connected to the plumb bob, and the plumb bob is connected to the long rod two through the rotating ball three.

[0009] As a further preferred solution, it also includes a ground-inserting rod; and the seat plate is fixedly connected with a plurality of ground-inserting rods.

[0010] As a further preferred solution, a transparent windshield plate is fixedly connected to the front and rear sides of the gantry, and the prism is located between the two transparent windshield plates.

[0011] As a further preferred solution, a widening plate is also included; the plumb bob is fixedly connected to the widening plate.

[0012] The utility model has the following advantages: the rotating ball can be rotated on the mounting block forward, backward, left or right in any direction, so that the prism can be driven to rotate on the mounting block under the influence of the weight of the counterweight block, so that the prism can be always in a vertical state, thereby avoiding the problem in the prior art that, because the prism is rotatably connected to the support frame, if the prism can be rotated in the front and back directions, that is, the prism cannot be rotated to the left or right, it is impossible to ensure that the prism will always be in a vertical state when the main body of the prior device is tilted;

[0013] By connecting the mounting block 2 and the rotating ball 2 via a universal shaft, the mounting block 2 cannot sequentially drive the plumb bob to move via the rotating ball 2, the long rod 1, the long rod 2, the fixed rod and the rotating ball 3, thereby avoiding the problem in the prior art that the plumb bob will be tilted or not at the test point because the existing device will pull the plumb bob to move via the hanging rope;

[0014] By fixing a widening plate on the lower side of the plumb bob, the contact area between the plumb bob and the soil at the bottom of the foundation pit is increased, so as to avoid the problem that the plumb bob is easily inserted into the soil at the bottom of the foundation pit under the influence of its own weight.

[0024] It also includes a gantry 6, a mounting block 7, a rotating ball 8, a prism 9, a counterweight 10, a plumb bob 11 and an adjustment assembly; the mounting plate 4 is fixedly connected to the gantry 6; the gantry 6 is fixedly connected to the mounting block 7; the mounting block 7 is connected to the rotating ball 8 through a universal shaft; the rotating ball 8 is fixedly connected to the prism 9; the prism 9 is fixedly connected to the counterweight 10 for keeping it in a vertical state at all times; the mounting plate 4 is connected to the adjustment assembly; the adjustment assembly is connected to the plumb bob 11 for cooperating with the prism 9 so that the total station can accurately measure the deformation of the bottom of the foundation pit; the adjustment assembly is used to adjust the position of the plumb bob 11.

[0025] The adjustment component includes an electric push rod 101, a mounting block 102, a rotating ball 103, a long rod 104, a long rod 105 and a fixed rod 106; the mounting plate 4 is fixedly connected to the electric push rod 101; the telescopic part of the electric push rod 101 is fixedly connected to the mounting block 102; the mounting block 102 is connected to the rotating ball 103 through a universal shaft; the rotating ball 103 is fixedly connected to the long rod 104; the long rod 104 is slidably connected to the long rod 105, and the long rod 105 is connected to the plumb bob 11; the long rod 104 is screwed to the fixed rod 106, and the fixed rod 106 is in contact with the long rod 105, and the fixed rod 106 is used to prevent the long rod 105 from sliding in the long rod 104.

[0026] The adjustment component also includes a rotating ball three 107; the long rod two 105 is connected to the rotating ball three 107 through a universal shaft, and the rotating ball three 107 is fixedly connected to the plumb bob 11, and the plumb bob 11 is connected to the long rod two 105 through the rotating ball three 107.

[0027] It also includes a ground-inserting rod 201; the base plate 1 is fixedly connected with four ground-inserting rods 201, and the ground-inserting rods 201 are used to more firmly fix the base plate 1 and the parts connected thereto on the bottom of the foundation pit.

[0028] A transparent windshield is fixedly connected to the front and rear sides of the gantry 6, and the prism 9 is located between the two transparent windshields. This arrangement is used to prevent the prism 9 from swaying under the influence of the outside world, thereby affecting the real-time data collection and perception work of the foundation pit.

[0029] The specific operation of the above embodiment 1 is as follows: First, Figure 4As shown, the device is placed at a position near the test point at the bottom of the foundation pit, and the seat plate 1 and the parts connected thereto are fixed more firmly to the bottom of the foundation pit by inserting the ground rod 1 201, and then the telescopic part of the electric push rod 1 5 is controlled to push the mounting plate 4 and the parts connected thereto to move upward, so that the height of the prism 9 is at a position where the total station outside the foundation pit can observe, and the height of the prism 9 is measured. At the same time, the mounting plate 4 moving upward will drive the electric push rod 2 101 and the parts connected thereto to move upward, so that the plumb bob 11 is above the bottom of the foundation pit, and then the telescopic part of the electric push rod 2 101 is controlled to push the mounting block 2 102 and the parts connected thereto to move upward. Move toward the pit bottom test point close to the foundation pit until the plumb bob 11 is directly above the pit bottom test point of the foundation pit, and then manually rotate the fixed rod 106 to move away from the long rod 2 105, so that the fixed rod 106 is no longer in contact with the long rod 2 105, thereby releasing the fixation of the fixed rod 106 to the long rod 2 105, and then manually pull the long rod 2 105 downward on the long rod 1 104, so that the long rod 2 105 drives the fixed rod 106, the rotating ball 3 107 and the plumb bob 11 to move downward until the plumb bob 11 contacts the pit bottom test point of the foundation pit, at which time, the long rod 1 104, the long rod 2 105 and the plumb bob 11 are in a vertical state;

[0030] Then, the height of the prism 9 measured by the total station and the height difference between the prism 9 and the plumb bob 11 can be used to obtain the uplift deformation data of the pit bottom test point, thereby realizing the real-time data collection and perception work of the foundation pit;

[0031] It should be noted that when the bottom of the foundation pit is bulging and deforming, Figure 5 As shown, the seat plate 1 will tilt synchronously with the deformation of the pit bottom, and the mounting frame 2, the support plate 3, the mounting plate 4, the electric push rod 5 and the gantry 6 will also tilt synchronously under the drive of the seat plate 1. Since the rotating ball 8 and the mounting block 7 are connected by a universal shaft, that is, the rotating ball 8 can rotate on the mounting block 7 to any direction forward, backward, left or right, then no matter the seat plate 1, the mounting frame 2, the support plate 3, the mounting plate 4, the electric push rod 5 and the gantry 6 are tilted to any direction forward, backward, left or right, the prism 9 can drive the rotating ball 8 to rotate on the mounting block 7 under the influence of the weight of the counterweight 10, so that the prism 9 can be kept in a vertical state all the time, thereby avoiding the problem in the prior art that, since the prism 9 and the supporting frame are rotatably connected, if the prism 9 can rotate in the front and back directions, that is, the prism 9 cannot rotate to the left or right, it is impossible to ensure that the prism 9 will always be in a vertical state when the main body of the prior art is tilted;

[0032] And, if Figure 5As shown, during the tilting process of the seat plate 1, the mounting frame 2, the support plate 3, the mounting plate 4, the electric push rod 1 5 and the gantry 6, the mounting plate 4 will drive the electric push rod 2 101 and the mounting block 2 102 to tilt synchronously, and the long rod 104 is connected to the mounting block 2 102 by the rotating ball 2 103. When the mounting block 2 102 tilts, the mounting block 2 102 will rotate about its axis with the rotating ball 2 103, that is, when the mounting block 2 102 tilts, the mounting block 2 102 will not drive the long rod 1 104 and the parts connected thereto to tilt by the rotating ball 2 103. The mounting block 2 102 cannot drive the plumb bob 11 to move by the rotating ball 2 103, the long rod 1 104, the long rod 2 105, the fixed rod 106 and the rotating ball 3 107 in sequence. This can avoid the problem in the prior art that the plumb bob 11 will tilt or be not at the test point because the existing device will pull the plumb bob 11 to move by the hanging rope;

[0033] It should be noted that, after the device is installed, it is not necessary to make the fixing rod 106 contact with the second long rod 105, that is, the second long rod 105 can slide freely in the first long rod 104. Therefore, when the second mounting block 102 is tilted, the second long rod 105 can move upward or downward in the first long rod 104 to supplement the distance between the second mounting block 102 and the plumb bob 11.

[0034] Considering that there must be friction between the second mounting block 102 and the second rotating ball 103, and friction will also be generated when the second mounting block 102 drives the second long rod 105 to move upward or downward in the first long rod 104 through the second rotating ball 103, then when the second mounting block 102 is tilted, under the action of friction, the second mounting block 102 can easily drive the plumb bob 11 to tilt through the second rotating ball 103, the first long rod 104 and the second long rod 105, causing the plumb bob 11 to no longer be in a vertical state;

[0035] Therefore, by providing the rotating ball three 107 on the long rod two 105, the rotating ball three 107 is fixedly connected to the plumb bob 11, so that when the rotating ball two 103 drives the long rod one 104 and the long rod two 105 to tilt, the long rod two 105 will tilt at its rotation point with the rotating ball three 107, and will not drive the plumb bob 11 to tilt through the rotating ball three 107. In this way, it can be avoided that the mounting block two 102 can easily drive the plumb bob 11 to tilt through the rotating ball two 103, the long rod one 104 and the long rod two 105, resulting in the problem that the plumb bob 11 is no longer in a vertical state.

[0036] Example 2

[0037] On the basis of Example 1, Figure 3 As shown, a widening plate 301 is also included; the plumb bob 11 is fixedly connected to the widening plate 301 for preventing it from being inserted into the soil at the bottom of the foundation pit.

[0038] The specific operation of the above-mentioned embodiment 2 is as follows: In embodiment 1, when the device is installed, since the second long rod 105 can slide freely in the first long rod 104, and the bottom of the foundation pit is usually prone to water accumulation, that is, the soil at the bottom of the foundation pit is in a soft state, when the plumb bob 11 contacts the test point at the bottom of the foundation pit, the plumb bob 11 is easily inserted into the soil at the bottom of the foundation pit under the influence of its own weight, thereby causing the distance between the plumb bob 11 and the prism 9 to change, resulting in errors in the data measured by the total station;

[0039] Therefore, by fixing the widening plate 301 on the lower side of the plumb bob 11, the contact area between the plumb bob 11 and the soil at the bottom of the foundation pit is increased to avoid the problem that the plumb bob 11 is easily inserted into the soil at the bottom of the foundation pit under the influence of its own weight.

[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
