Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, in particular to a settlement measurement and analysis device for the foundation of an underground structure area. Background Art

[0002] Common underground structures include underground parking lots, air-raid shelters, subways, and underground plazas. After pouring the foundation, the foundations of these areas need to be immediately tested for settlement, which requires the use of the above-mentioned settlement measurement and analysis equipment.

[0003] Existing settlement measurement and analysis equipment primarily consists of a frame, a measuring instrument mounted on the frame, a base, and a measuring scale mounted on the base. These measuring instruments are primarily rangefinders or cameras, each operating on slightly different principles. The former measures the distance between itself and a marker on the measuring scale, calculating the foundation settlement based on the difference in these distances. The latter, on the other hand, directly takes a photograph and reads the settlement based on the difference in the scale readings in the center of the photograph.

[0004] On the other hand, the functions of the frame and base are the same. No matter which measuring instrument is used in the settlement measurement and analysis equipment, the frame needs to be installed horizontally, and the base is used to ensure that the measuring ruler is vertical before the settlement detection.

[0005] Ultimately, whether settlement occurs in the foundation area at the frame or the base, the settlement measurement and analysis equipment can generally detect it.

[0006] For example, the Chinese utility model patent with authorization announcement number CN220960061U and authorization announcement date 2024.05.14 discloses a building foundation settlement measuring device, including a mounting frame, an infrared measuring mechanism, a measuring adjustment mechanism and a measuring ruler. The mounting frame is vertically arranged, the measuring ruler is vertically arranged beside the mounting frame, the infrared measuring mechanism is arranged on the mounting frame, and the measuring adjustment mechanism is located on the mounting frame.

[0007] The general structural principle and advantages of the settlement measuring device in this utility model patent are as follows: by observing the bubble level on the balance board, if there are uneven areas in the foundation settlement area, the position can be adjusted so that the mounting frame is in a horizontal and balanced state, so that the measured data is accurate when measuring the distance of the base.

[0008] However, in actual use, the settlement measuring device still has at least the following shortcomings, which are also the technical problems to be solved by the present utility model, namely:

[0009] After the measuring scale structure changes the detection position, the mounting bracket must be moved and rotated to align the infrared measuring instrument with the measuring scale again, which is very impractical.

[0010] Therefore, in summary, there is an urgent need for a new type of measuring and analyzing device with a flexible adjustable orientation of the measuring instrument, so as to make it convenient and fast enough when performing multi-point detection on the foundation of the underground structure area. Utility Model Content

[0011] The utility model provides a settlement measuring and analyzing device for the foundation of the underground structure area. By setting a leveling screw unit, a horizontal ring unit, a rotating frame unit, and a measuring instrument on the support frame body unit, it can be ensured that: the measuring instrument can rotate horizontally, ensuring that it is relatively simple and convenient during the process of detecting multiple measuring scales or when the measuring scale is displaced, without the need to move or rotate the entire device.

[0012] The technical solution adopted by the utility model to solve the above problems is: a settlement measuring and analyzing device for the foundation of the underground structure area, the structure includes a measuring instrument, and also includes a support frame body unit, a leveling screw unit arranged on the support frame body unit, a horizontal ring unit arranged on the support frame body unit, and a rotating frame unit sleeved on the horizontal ring unit and used for installing the measuring instrument.

[0013] A further preferred technical solution lies in that: the support frame body unit includes a bottom plate, a column arranged on the bottom plate and used for installing the horizontal ring unit, and a screw hole arranged on the bottom plate and used for installing the leveling screw unit.

[0014] A further preferred technical solution lies in that: the leveling screw unit includes a vertical screw arranged on the screw hole, a vertical round rod arranged on the lower end surface of the vertical screw, a support plate, and a circular groove arranged on the upper surface of the support plate and used for inserting the vertical round rod.

[0035] The following is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.

[0036] As shown in the attached Figures 1-7 As shown, a settlement measurement and analysis device for the foundation of an underground structure area includes a measuring instrument 11, and also includes a support frame unit 1, a leveling screw unit 2 arranged on the support frame unit 1, a horizontal ring unit 3 arranged on the support frame unit 1, and a rotating frame unit 4 sleeved on the horizontal ring unit 3 and used for installing the measuring instrument 11.

[0037] In this embodiment, the measuring instrument 11 is a common existing rangefinder or camera, and can be selected to be used with a computer as needed, and finally achieve the above-mentioned purpose of "measurement and analysis".

[0038] Among them, the direct function of the leveling screw unit 2 is to make the support frame unit 1 vertical and stable, and its indirect function is to provide a stable and horizontally rotatable track for the measuring instrument 11, and the horizontal ring unit 3 is the above-mentioned track.

[0039] Finally, the function of the rotating frame unit 4 is: on the premise that the support frame unit 1 is vertical, it is also vertical, so as to ensure that the measuring instrument 11 can emit ranging laser / infrared rays horizontally, or can stably take horizontal pictures, so that the multi-point detection operation of the settlement of the foundation in this area can be effectively and conveniently carried out.

[0040] Specifically, the above-mentioned multi-point detection operation can be to use a single measuring instrument 11 with multiple measuring rulers 12, or to take multi-point samples and rotate the placement of a single measuring ruler 12 on the foundation of this area.

[0041] Finally, both the support frame unit 1 and the measuring ruler 12 are adjusted to a vertical state. The measuring instrument 11 samples at the starting moment of the settlement detection period, or samples multiple groups at intervals during this period, and then compares the above data to obtain the settlement measurement result of the foundation in this area.

[0042] It should be noted in particular that when an obvious settlement phenomenon is detected, it is possible for the settlement phenomenon to occur at the above-mentioned measuring instrument 11 or the measuring scale 12.

[0043] The support frame unit 1 includes a bottom plate 101, a column 102 disposed on the bottom plate 101 and used for installing the horizontal ring unit 3, and a screw hole 103 disposed on the bottom plate 101 and used for installing the leveling screw unit 2.

[0044] In this embodiment, the main material of the support frame unit 1 is stainless steel or aluminum alloy, the shape of the bottom plate 101 is rectangular or circular, and the column 102 can be a cylinder or a square column, and the two are integrally formed.

[0045] The number of the screw holes 103 is 4, corresponding to the 4 leveling screw units 2, and the above 4 screw holes 103 are evenly spaced in the circumferential direction, so that the bottom plate 101 obtains a more symmetric, stable and comprehensive support effect.

[0046] The leveling screw unit 2 includes a vertical screw 201 disposed on the screw hole 103, a vertical round rod 202 disposed on the lower end surface of the vertical screw 201, a support plate 203, and a circular groove 204 disposed on the upper surface of the support plate 203 and used for inserting the vertical round rod 202.

[0047] In this embodiment, the vertical screw 201 is screwed with the screw hole 103, and the vertical round rod 202 is inserted into the circular groove 204. Thus, the leveling screw unit 2 can provide an adjustable vertical support effect for the bottom plate 101.

[0048] It should be noted that when leveling the bottom plate 101, the vertical screw 201 does not need to manually lift the bottom plate 101, and only the exposed part above the vertical screw 201 needs to be manually rotated.

[0049] In addition, it is precisely because the leveling screw unit 2 is provided that the support frame unit 1 can be adjusted to a vertical state and maintained at, for example, a foundation pit a, a protrusion, or a slope.

[0050] The horizontal ring unit 3 includes 2 horizontal rings 301 sleeved on the column 102, and a radial rod 302 disposed on the column 102 and used for connecting the horizontal rings 301.

[0051] In this embodiment, 3-4 radial rods 302 are provided on the horizontal ring 301, and the column 102, the radial rod 302 and the horizontal ring 301 are integrally formed.

[0052] The rotating frame unit 4 includes two open rings 401 respectively arranged on the two transverse rings 301 and used for passing through the radial rods 302, two vertical connecting rods 402 respectively arranged on the two open rings 401, and a transverse U-shaped plate 403 with upper and lower ends respectively arranged on the two vertical connecting rods 402, with an opening facing radially outward and used for installing the measuring instrument 11.

[0053] In this embodiment, the opening structure on the open ring 401 enables it not to touch the radial rod 302 during rotation, avoiding the radial rod 302 from restricting the lateral rotation angle of the measuring instrument 11, allowing the latter to rotate a complete circle.

[0054] Among them, the entire rotating frame unit 4 is integrally formed. The transverse U-shaped plate 403 is horizontally placed with an opening facing radially outward to ensure that there are no obstacles in the laser / infrared emission path or the shooting path of the measuring instrument 11.

[0055] In addition, mounting screw holes are provided on the three plate bodies forming the transverse U-shaped plate 403, enabling the transverse U-shaped plate 403 to have a high degree of adaptability to the measuring instrument 11.

[0056] The support frame unit 1 further includes a circular top plate 104 arranged on the upper end face of the column 102 and used for covering and protecting the rotating frame unit 4.

[0057] In this embodiment, the main function of the circular top plate 104 is to cover and protect the rotating frame unit 4 and the measuring instrument 11 thereon, making it difficult for inevitable falling objects to damage the rotating frame unit 4 and the measuring instrument 11.

[0058] Correspondingly, the diameter of the circular top plate 104 is larger than the outer diameter of the transverse ring 301.

[0059] The leveling screw unit 2 further includes a fastening nut 205 arranged on the vertical screw 201 and used for clamping the upper surface of the bottom plate 101.

[0060] In this embodiment, when the vertical screw 201 levels the bottom plate 101, the fastening nut 205 relatively moves away from the upper surface of the bottom plate 101. After the leveling operation of the vertical screw 201 is completed, it needs to be fixed first, and then the fastening nut 205 is rotated until the fastening nut 205 clamps the bottom plate 101.

[0061] Thus, the active leveling effect obtained at the vertical screw 201 is not easily changed spontaneously.

[0062] The leveling screw unit 2 further includes balls 206 disposed on the inner bottom surface of the circular groove 204 and used to support the vertical round rod 202.

[0063] In this embodiment, a ball groove for embedding and installing the balls 206 may be further provided on the inner bottom surface of the circular groove 204. The function of the balls 206 is as follows:

[0064] When the vertical screw 201 rotates for leveling, it can change the original sliding friction between the vertical round rod 202 and the inner bottom surface of the circular groove 204 into rolling friction. Therefore, the friction resistance is smaller, and the rotation operation of the vertical screw 201 is more labor-saving and convenient.

[0065] However, it should be noted that: due to the setting of the balls 206, higher requirements are put forward for the material hardness of the vertical round rod 202 and the support plate 203. Generally, the above-mentioned stainless steel or aluminum alloy can be applicable, while other materials such as rubber are generally not applicable.

[0066] The rotating frame unit 4 further includes positioning bolts 404 disposed on the open ring 401 and used to clamp the transverse ring 301.

[0067] In this embodiment, the positioning bolts 404 are rubber bolts. When the rotating frame unit 4 rotates, it is separated from the transverse ring 301. When the rotating frame unit 4 rotates to the in-place position and the measuring instrument 11 faces the measuring scale 12, it is tightened inward to prevent the measuring instrument 11 from spontaneously rotating and displacing.

[0068] The support frame unit 1 further includes a measuring scale storage hole 105 provided on the circular top plate 104.

[0069] In this embodiment, the measuring scale storage hole 105 is used to insert and store the above-mentioned measuring instrument 11 when it is not in use. Its circumferential position is staggered from the radial rod 302, so that when the measuring instrument 11 is inserted and stored, its lower end can be directly placed on the bottom plate 101.

[0070] Thus, when the measurement and analysis device is stored and transported, the degree of scattering of each part can be greatly reduced. When the measurement and analysis device is in use, the above-mentioned measuring instrument 11 that is not temporarily used also has a fixed placement position, and it does not need to be placed on the ground randomly, otherwise it is easy to be damaged by being pressed.

[0071] Among them, the number of the measuring scale storage holes 105 is 1-4, and the shape is rectangular.

[0072] The embodiments of the present utility model have been described in detail in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the gist of the present utility model. These are all non-creative modifications and are protected by the Patent Law as long as they are within the scope of the claims of the present utility model.
