Description

Continuous foundation pit distance measuring device

Technical Field

The utility model relates to the technical field of building construction engineering, in particular to a continuous foundation pit ranging device.

Background

So-called "continuous pit," a special structure in construction engineering, is commonly used for deep pit excavation in confined spaces to accommodate underground structures or facilities. This type of foundation pit has a greater depth and a longer length than a general foundation pit and a structure of an array arrangement, and thus requires more complicated and precise design and construction methods. Typical application scenarios for continuous pit include underground parking lots, underground malls, underground stations, etc.

Continuous foundation pits are often applied to urban centers or crowded areas, and the distance between adjacent foundation pits is directly related to construction safety. Therefore, in the prior art, the accurate distance measurement of the continuous foundation pit can avoid the mutual influence between foundation pits, and the unstable structure of the adjacent foundation pit caused by excavation is prevented. Meanwhile, the distance between the continuous foundation pits has direct influence on the design and construction of the supporting structure. Through accurate range finding, the engineer can monitor the deformation of soil body better, takes measures in time and prevents unnecessary subsidence or displacement.

In the prior art, the total station is a multifunctional measuring tool, can measure horizontal angle, vertical angle and inclined distance at the same time, and provides omnibearing measuring data. In continuous pit engineering, a constructor typically uses a total station to perform multiple loftings, i.e., perform measurements at different orientations and times, to obtain more accurate distance and position information between adjacent pits. The method for multiple lofting is beneficial to detecting deformation and displacement of the foundation pit in different construction stages, and timely finding potential safety hazards. Meanwhile, the data provided by the total station can be used for monitoring the stability of the foundation pit supporting structure, and smooth progress of foundation pit construction is ensured.

If the foundation pit is considered as a solid geometry, the total station can only measure in one direction two sides perpendicular to the direction and two sides intersecting the sides. This means that the measurement from one direction cannot capture the entire geometric information of the pit, since the other two sides and the corresponding sides cannot be measured directly. In colloquial terms, for a measurement site, the total station is able to measure both sides of the pit perpendicular to this orientation and both sides of the intersection. But it will not be possible to measure the other two sides of the pit and the two sides intersecting these sides. Therefore, at least 4 sides of the foundation pit cannot be measured. In the prior art, therefore, it is necessary for the constructor to perform the loft at different positions. Therefore, the following technical problems need to be solved in this conventional technology:

(1) Time and resource cost issues: making multiple ranging requires more time and resources.

(2) Instrument operation complexity increases: setting up total stations in different orientations requires careful instrument manipulation and conversion of the coordinate system, which adds to the complexity of the operation and possible human error.

(3) Local features may be ignored: even if ranging is performed in multiple directions, local features may be ignored because they are small or insignificant, resulting in inaccurate distance information for certain local areas of the foundation pit.

For this purpose, a continuous pit ranging device is proposed.

Disclosure of utility model

In view of the foregoing, it is desirable to provide a continuous pit ranging apparatus that solves or mitigates the technical problems of the prior art, namely time and resource cost, increased complexity of instrument operation, and possibly neglected local features, and provides at least one advantageous option therefor.

The two ends of the spiral propelling roller are connected to the frame through running fit, and meanwhile, the output shaft of the servo motor is fixedly connected with the center shaft of the spiral propelling roller.

Wherein in one embodiment: the step-up and down component consists of a plurality of air bags. The upper surface and the lower surface of each air bag are connected with a fixed disc in a sealing way, and each air bag is fixedly connected with the fixed disc of other air bags through the respective fixed disc. The airbags are sequentially overlapped from bottom to top, and when the airbags are inflated, the capacity of each airbag is equal, so that the inflated height of the airbags is kept at a fixed value, and the lifting adjustment in a stage form is realized.

The air supply group is used for supplying air to the air bags of the stepped lifting assembly. The air supply group comprises a compressed air bottle, an electromagnetic valve communicated with the compressed air bottle, an air pump communicated with the electromagnetic valve and an air supply pipe communicated with an air outlet of the air pump. The air supply pipe is led out for a long enough distance and is communicated with the other electromagnetic valve carried in the fixed disc. The solenoid valve is in turn connected to an air bag, thereby controlling whether the air bag needs to be inflated.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. This utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below;

In the prior art, if the total station is fixed in only one orientation, it can only measure the sides of the pit in the plane of this orientation from this orientation. While the pit acts as a geometrical body, some of its edges are based on the principle of perspective, which is not in this plane and therefore cannot be measured. In particular, if the orientation of the total station is fixed, it can measure both sides of the pit perpendicular to this orientation and both sides of the intersection. But it will not be possible to measure the other two sides of the pit and the two sides intersecting these sides. Therefore, at least 4 sides in total cannot be measured, and thus, a worker is required to perform at least one more loft at different positions. After the situation is characterized, the problems of time and resource cost, increased complexity of instrument operation and possibly neglected local characteristics are brought; for this reason, referring to fig. 1-5, the present embodiment provides a related technical solution to solve the above technical problems: the continuous foundation pit distance measuring device comprises a plurality of unmanned total stations 1 for measuring different foundation pits, four self-propelled adjusting mechanisms 3 which are arranged in an annular array manner, and a telescopic truss mechanism 2 which is arranged at a central point surrounded by all the self-propelled adjusting mechanisms 3; each self-walking adjusting mechanism 3 performs self-walking through the self-walking assembly 301, performs step-wise lifting adjustment through the step-wise lifting assembly 302, and establishes connection with the telescopic truss mechanism 2 through the top frame 303;

When the self-propelled adjusting mechanism 3 performs self-propelled or/and performs stepped lifting adjustment, the telescopic truss mechanism 2 passively performs horizontal telescopic and height adjustment, and when each self-propelled adjusting mechanism 3 performs stepped lifting adjustment of different levels, the top frame 303 passively performs stepped orientation angle adjustment;

When the telescopic truss mechanism 2 performs any one or more actions in the passive execution, the plurality of groups of unmanned total stations 1 mounted on the telescopic truss mechanism relatively execute the adjustment of the reference point.

In the scheme, the method comprises the following steps: the self-propelled adjustment mechanism 3 achieves multi-dimensional adjustment. The self-propelled assembly 301 achieves movement of the mechanism, the stepped elevation assembly 302 achieves adjustment in the vertical direction through elevation adjustment of different levels, and the top frame 303 achieves angle adjustment in the horizontal direction when elevation adjustment of a stepped form is performed. The telescopic truss mechanism 2 passively performs horizontal telescopic and height adjustment, and at the same time, transmits an adjustment motion to the top frame 303.

Specific: the device has the function of realizing the accurate adjustment of the height and the horizontal position among a plurality of foundation pits. Through the flexibility of self-propelled adjustment mechanism 3, can remove between different foundation ditch, step lift adjustment and angle adjustment to ensure the accurate adjustment of total powerstation 1 for the reference point. The self-adaptability of the whole system enables accurate ranging information to be obtained under different foundation pit situations, and the system is suitable for complex foundation pit shapes and environments.

Preferably, the model number of the unmanned total station 1 is DJI Phantom, 4 and RTK.

In some embodiments of the present application, please refer to fig. 2-3 in combination: the device is specifically configured by arranging four self-propelled adjusting mechanisms 3 in an annular array, and the telescopic truss mechanism 2 is positioned in the general outline established in the middle. The self-propelled adjustment mechanism 3 has three functions:

Firstly, all self-propelled assemblies 301 synchronously approach or depart from each other at a uniform speed, and the telescopic truss mechanism 2 is controlled to horizontally stretch, and in the mode, a plurality of unmanned total stations 1 are driven to keep a uniform horizontal plane, but approach or depart from each other;

Secondly, all self-propelled assemblies 301 synchronously travel in the same direction at a constant speed, and the telescopic truss mechanism 2 is controlled to self-propelled, and the telescopic truss mechanism 2 and the unmanned total stations 1 are driven to adapt to the construction environment in the mode;

thirdly, the step lifting assembly 302 works to control the telescopic truss mechanism 2 to perform step-type height adjustment, namely, take over-type height adjustment with a multiple of a certain fixed value, and under the mode, the telescopic truss mechanism 2 is driven to perform inclination angle adjustment;

For the third mode, since the self-propelled adjusting mechanisms 3 are arranged in a ring-shaped array, that is, the distance between each self-propelled adjusting mechanism 3 and the center of the telescopic truss mechanism 2 is equal, when each self-propelled adjusting mechanism 3 performs lifting adjustment in a different form but in a stepped form, the inclination of the telescopic truss mechanism 2 is still a preset standard value which is maintained, and the preset standard value refers to a spatial attitude point which is beneficial to the reference point of the unmanned total station 1.

In this scheme, referring to fig. 4 to 5, after the ranging direction requirement of the current construction site is clear, and after the execution of the three modes is completed, that is, after the reference position of each unmanned total station 1 is clear, the ranging information of different directions of a single group or multiple groups of foundation pits in the continuous foundation pit can be measured at one time. In the figure dHD denotes a horizontal distance, dSD denotes an inclined distance, and dVD denotes a height difference; in order to simplify the image information and clearly show the lofting lines, the height and angle of each unmanned total station 1 are kept consistent; in fig. 4, for clearly showing the loft line, the slope distance dSD measurement mode is shown separately, but in practice, dHD, dSD and dSD can be measured synchronously for one foundation pit; and performs an opposite side measurement mode of the conventional total station, including:

(1) The opposite side was measured a-B, a-C, a-d.

(2) Adjacent opposite edges a-B, B-C, C-d.

It is to be noted that when restriction of one unmanned total station 1 is caused based on projection, the unmanned total station 1 of the other direction symmetrical thereto makes a measurement of the restricted area detected by the above-described unmanned total station 1.

It should be noted that, the modes shown in fig. 4 to 5 are modes of the device placed on a plane, but in practice, the device can be correspondingly adapted and carried in a plurality of foundation pits according to a large-span structural design shown in fig. 1, and can be better adapted to different environments by matching with a spiral pushing roller 3013 structure described later. But it is necessary to ensure that the ground level of each pit is at the same level.

In the scheme, the method comprises the following steps: the annular array layout of the self-propelled adjusting mechanisms 3 ensures that the distance between the centers of the telescopic truss mechanisms 2 is equal, so that the inclination of the telescopic truss mechanisms 2 still maintains a preset standard value even when each self-propelled adjusting mechanism 3 performs stepped lifting adjustment of different levels. This standard value refers to a spatial attitude point advantageous for the reference point of the unmanned total station 1.

Specific: through the three functions, the embodiment realizes the comprehensive distance measurement of the continuous foundation pit. Firstly, horizontally stretching and retracting to ensure that the total station is on the same horizontal plane; secondly, the self-walking function enables the telescopic truss mechanism 2 to adapt to the construction environment; finally, the stepped form of height adjustment maintains the beneficial spatial pose of the datum point. The device can efficiently and accurately measure distance information in a complex foundation pit construction environment.

Specifically, the above "beneficial spatial attitude point location" refers to that in the foundation pit ranging device, through the annular array arrangement of the self-propelled adjusting mechanisms 3, when each self-propelled adjusting mechanism 3 performs lifting adjustment in different forms but in a stepped form, the inclination of the telescopic truss mechanism 2 can be kept at a preset standard value. This standard value effectively represents a spatial pose that is beneficial for the reference point of the unmanned total station 1.

Further, "beneficial spatial pose points" include the following:

(1) Horizontal plane: maintaining a horizontal plane is very critical in pit ranging, as this ensures accuracy and comparability of the measurements. The advantageous spatial attitude point location may require that the inclination of the telescopic truss mechanism 2 be approaching zero in the horizontal direction to ensure consistency of the foundation pit ranging data with respect to the horizontal plane.

(2) Vertical direction: the depth of the pit is often an important measure. The advantageous spatial attitude point may require that the inclination of the telescopic truss mechanism 2 approach a preset standard value in the vertical direction to ensure that the measured data accurately reflects the depth of the foundation pit.

(3) And (3) angle adjustment: sometimes, the pit may take a certain inclination or a complex shape, and the beneficial spatial attitude point may require that the inclination of the telescopic truss mechanism 2 can be adjusted angularly within a preset standard value to adapt to the shape characteristics of the pit.

In some embodiments of the present application, please refer to fig. 2-3 in combination: the self-propelled assembly 301 includes a frame 3011, a servo motor 3012 mounted on the frame 3011, i.e., rolling bodies driven by the servo motor 3012; when the rolling elements are driven to rotate by the servo motor 3012, execution of self-walking is achieved.

In the scheme, the method comprises the following steps: the frame 3011 of the self-propelled assembly 301 provides a support structure, and the servo motor 3012 is a key element for driving the rolling elements. When the servo motor 3012 drives the rolling elements to rotate, the entire self-propelled assembly 301 can perform self-walking in the apparatus. The precise control of the servo motor 3012 enables the self-propelled adjustment mechanism 3 to achieve synchronous uniform motion in the required direction, providing flexibility to the device.

In the scheme, all electrical components of the whole device are powered by a storage battery arranged in a frame 30111; specifically, the electric elements of the whole device are in conventional electrical connection with the output port of the storage battery through a relay, a transformer, a button panel and other devices, so that the energy supply requirements of all the electric elements of the device are met.

Specifically, a controller is further arranged outside the device and is used for connecting and controlling all electrical elements of the whole device to drive according to a preset program as a preset value and a drive mode; it should be noted that the driving mode corresponds to output parameters such as start-stop time interval, rotation speed, power and the like between related electrical components, and meets the requirement that related electrical components drive related mechanical devices to operate according to the functions described in the related electrical components.

Preferably, the controller is also provided with a wireless transmitting module and a wireless receiving module, and the wireless transmitting module sends out an instruction signal of working or suspending to the wireless receiving module through a medium; when necessary, a worker can input an instruction to the wireless transceiver module through a background wireless remote control device so as to remotely control a controller, and further, all electric elements of the device are remotely controlled to drive according to a related driving mode; meanwhile, the wireless transceiver module can also transmit the relevant coefficients or other information detected by the relevant sensing elements or the servo driving element system in the device to the background staff.

Specific: by driving the servo motor 3012, the self-propelled unit 301 controls the self-propelled adjustment mechanism 3. The characteristics enable the whole device to flexibly perform synchronous uniform self-propelled movement, and meet the requirements of positions under different construction scenes. The accurate control of the servo motor 3012 ensures the stability and accuracy of self-walking and provides a reliable basis for realizing the distance measurement of a continuous foundation pit.

Preferably, the frame 3011 is composed of two mutually rotatably matched frame bodies, wherein the lower frame body is matched with the servo motor 3012 and the rolling bodies, and the upper frame body is matched with the air supply group 304 and the stepped lifting assembly 302; and an adjusting motor is arranged in the upper frame body, and an output shaft of the adjusting motor is fixedly connected with the lower frame body, so that the roller body can be adjusted to steer.

In some embodiments of the present application, please refer to fig. 2-3 in combination: the rolling bodies are spiral pushing rollers 3013, two ends of each spiral pushing roller 3013 are in rotary fit with the frame 3011, and an output shaft of the servo motor 3012 is fixedly connected with a center shaft of each spiral pushing roller 3013.

In the scheme, the method comprises the following steps: the auger roller 3013 is a key component for achieving self-walking in this embodiment. Both ends of which are connected to the frame 3011 by a running fit so that the entire rolling body can rotate on the frame 3011. The output shaft of the servo motor 3012 is fixedly connected to the central shaft of the spiral pushing roller 3013, and the spiral pushing roller 3013 can realize the rotation pushing motion by the driving of the servo motor 3012.

Specific: by employing the spiral pusher roller 3013, self-walking on the frame 3011 is achieved. The special design of the spiral pushing roller 3013 enables the spiral pushing roller 3013 to push while rolling, and precise control of the self-propelled adjusting mechanism 3 is achieved. The servo motor 3012 is connected to the auger roller 3013 by its output shaft, providing power to rotate the auger roller 3013, thereby pushing the movement of the self-propelled adjustment mechanism 3. The design ensures the stability and controllability of self-walking and provides a reliable power source for the operation of the distance measuring device.

It should be noted that the form and principle of the spiral propulsion roller 3013 can be referred to as a spiral propulsion car (Propeller car) in the conventional sense, which is a special vehicle suitable for running on severe terrains such as snowfield and mud, and the like, and in 1868, the inventor Jacob Morath proposed that finished products such as SHN-1 type all-terrain vehicles are manufactured by James and IRA PEAVEY in 1907. Therefore, when the spiral propulsion roller 3013 designed by the technology is adopted, the spiral propulsion roller 3013 can be more suitable for different environmental conditions than the forms of tracked vehicles and the like;

In some embodiments of the present application, please refer to fig. 2-3 in combination: the stepped lift assembly 302 includes a number of air bags 3021; the upper surface and the lower surface of the air bags 3021 are hermetically connected with a fixing disk 3022, and each air bag 3021 is fixedly connected with the fixing disk 3022 of the other air bags 3021 through the respective fixing disk 3022; each balloon 3021 is arranged in sequence one above the other from bottom to top. When the air bags 3021 are inflated, since the capacity of each air bag 3021 is equal, the height is a fixed value after the inflation thereof. In this mode, the stepped form of lifting adjustment described above is achieved.

In the scheme, the method comprises the following steps: the sealing connection and stacking arrangement of the air bags 3021 constitutes the basic structure of the stepped riser assembly 302. The height of the balloon 3021 reaches a fixed value due to the equal capacity when inflated. This design ensures that the air bags 3021 have a predictable height in the inflated condition and that the connection between the air bags 3021 by the fixing plate 3022 maintains a fixed relative position so that the lifting adjustment can be performed at a predetermined level.

Specific: by employing the air bag 3021 as the stepped elevation assembly 302, the height adjustment of the telescopic truss mechanism 2 is achieved. The constant volume design of the air bags 3021 ensures that the height of each air bag 3021 is equal after inflation, thereby achieving a stepped form of lift adjustment. This mode has the advantage of high controllability and is very suitable for situations where a precise height adjustment is required.

In some embodiments of the present application, please refer to fig. 2-3 in combination: also included is an air supply assembly 304 carried on the frame 3011, the air supply assembly 304 being configured to supply air to the air bags 3021 of the stepped riser assembly 302. The air supply set 304 includes a compressed air cylinder, an electromagnetic valve communicated with the compressed air cylinder, an air pump communicated with the electromagnetic valve, and an air supply pipe 3041 communicated with an air outlet of the air pump, wherein the air supply pipe 3041 is led out a long enough distance and is communicated with another electromagnetic valve carried in the fixed disk 3022, and the electromagnetic valve is communicated with an air bag 3021, so as to control whether the air bag 3021 needs to be inflated.

In the scheme, the method comprises the following steps: the basic structure of the air supply unit 304 includes a compressed air cylinder, a solenoid valve, an air pump, and an air supply pipe 3041. The solenoid valve supplies air through a compressed air cylinder and the air pump delivers the air to the air supply pipe 3041. The outlet of the gas supply tube 3041 is drawn a sufficient distance to connect with a solenoid valve within the bladder 3021. By controlling the solenoid valve, it is possible to determine whether to inflate the bladder 3021, thereby achieving height adjustment of the stage lift assembly 302.

Specific: the introduction of the air supply group 304 enables the control of the inflation of the airbag 3021 of the stepped riser assembly 302. By controlling the opening and closing of the solenoid valve, the inflation state of the air bag 3021 can be accurately adjusted, thereby achieving a stepwise adjustment of the height. The design ensures that the device has high controllability for the air bags 3021, and provides more flexible lifting adjustment function for the whole continuous foundation pit distance measuring device.

In some embodiments of the present application, please refer to fig. 2-3 in combination: the telescopic truss mechanism 2 comprises a central truss 201 and truss groups, the number of which is the same as that of the self-propelled adjusting mechanisms 3, each truss group is telescopic, and two ends of each truss group are respectively provided with an unmanned total station 1; one end of the truss group is fixedly arranged on the central truss 201, the other end of the truss group is fixedly provided with a connecting frame 203, and the connecting frame 203 is in connection with the top frame 303.

In the scheme, the method comprises the following steps: the basic structure of the telescopic truss mechanism 2 includes a central truss 201 and a plurality of truss groups. Each truss group can stretch out and draw back, and the unmanned total station 1 is carried at both ends. One end of which is directly fixed to the center truss 201 and the other end of which is connected to the top frame 303 through the connection frame 203. By controlling the telescopic state of the truss group, the horizontal telescopic adjustment of the telescopic truss mechanism 2 can be realized.

Specific: the design of the telescopic truss mechanism 2 enables the telescopic truss mechanism to flexibly adapt to the shape and the size of a foundation pit. Each truss group is provided with an unmanned total station 1, so that measurement data can be continuously acquired in the telescoping process. The connection relation of the connecting frame 203 ensures the close cooperation of the telescopic truss mechanism 2 and the top frame 303, thereby realizing the coordinated adjustment of the total station in the height and horizontal directions and providing more accurate position reference for distance measurement.

In some embodiments of the present application, please refer to fig. 2-3 in combination: the connection frame 203 is hingedly coupled to the top frame 303 by a universal joint coupling.

In the scheme, the method comprises the following steps: by using a universal joint coupling, the connection of the connection frame 203 with the top frame 303 achieves a hinged fit. This means that the link 203 can be freely rotated in multiple directions to accommodate different attitudes and angles. This flexible connection allows the connection frame 203 to be flexibly adjusted with the support of the top frame 303, ensuring the stability and adaptability of the whole telescopic truss mechanism 2.

Specific: the design of the connection frame 203 using the universal joint coupling increases the flexibility of the telescopic truss mechanism 2. The hinged cooperation of the connecting frame 203 and the top frame 303 enables the mechanism to freely rotate in different directions, and is suitable for complex foundation pit shapes and construction environments. The design improves the working efficiency and stability of the telescopic truss mechanism 2, and simultaneously ensures the accuracy of the distance measuring device.

In some embodiments of the present application, please refer to fig. 2-3 in combination: the truss group comprises a plurality of adjustable trusses 202 in hollow forms, wherein the adjustable trusses 202 are identical in shape and different in size, and each adjustable truss 202 is nested and matched in a sliding manner according to different sizes;

The adjustable truss 202 with the largest size is fixedly arranged in the center truss 201, and the top of the adjustable truss is provided with an unmanned total station 1; the adjustable truss 202 with the smallest size is fixedly arranged on the connecting frame 203, one end of the adjustable truss closest to the connecting frame 203 extends for a certain length, the length of the portion does not participate in sliding fit, and another unmanned total station 1 is arranged on the length of the portion.

In the scheme, the method comprises the following steps: the design of the adjustable trusses 202 allows them to slide nested within each other, decreasing in size. The largest dimension adjustable truss 202 is directly secured to the center truss 201, while the smallest dimension adjustable truss 202 is secured to the connector frame 203 with one end extending a length such that it does not participate in a slip fit. Thus, the unmanned total station 1 is mounted on top of each adjustable truss 202.

Preferably, both ends of each adjustable truss 202 are provided with conventional spacing structures for spacing and preventing the adjustable trusses 202 from being separated from each other.

Preferably, each adjustable truss 202 is triangular in shape for increased pressure resistance.

Specific: the design of the adjustable truss 202 increases the flexibility of the telescoping truss frame mechanism 2. Due to the size decrease, the truss group can flexibly stretch and retract as required, and the truss group is suitable for foundation pits with different depths. The unmanned total station 1 at the top of each adjustable truss 202 ensures that accurate measurement data can be obtained at the heights of different trusses, and provides a reliable reference point for the whole ranging device.

Summarizing, aiming at the related problems in the prior art, the specific embodiment is based on the continuous foundation pit ranging device provided by the above, and the following technical means or characteristics are adopted to realize the solution:

(1) Time and resource cost issues: by adopting the self-propelled adjusting mechanism 3 and the adjustable truss 202 group, the technology of the utility model realizes automatic measurement of the foundation pit without excessive human intervention. Thus, the measuring time can be greatly reduced, and the burden of human resources is also reduced. The automatic function of the self-propelled adjusting mechanism 3 enables the device to be adjusted autonomously in different directions, so that the overall time cost of foundation pit ranging is reduced.

(2) Instrument operation complexity increase problem: advanced equipment such as the self-propelled adjusting mechanism 3 and the unmanned total station 1 are adopted, so that the human intervention and the operation difficulty in the measuring process are reduced. The design makes the distance measuring device more intelligent, not only reduces the burden of operators, but also improves the accuracy of operation.

(3) Local features may be ignored: by distributing a plurality of unmanned total stations 1, particularly mounted on top of a set of adjustable trusses 202, the technique of the present utility model can more fully capture various aspects of a foundation pit. Each unmanned total station 1 can acquire data at different heights, so that the comprehensive measurement of each local characteristic of the foundation pit is ensured, and the possibility of neglecting the local characteristic is reduced.

Specific: the technology of the utility model mainly realizes the automatic measurement of the foundation pit through the intelligent cooperative work of the self-propelled adjusting mechanism 3, the adjustable truss 202 group and the total station in principle. The self-propelled adjusting mechanism 3 is self-propelled and the adjustable truss 202 group is telescopic, so that the whole device can adapt to foundation pits with different shapes and depths, and the problem that manual adjustment is needed in the traditional method is solved. The distribution of the plurality of unmanned total stations 1 ensures the comprehensiveness of the data, thus solving the problem of possible neglecting local features. The whole technical system is intelligent and automatic, so that the distance measuring process is more efficient and reliable.

Further, the device also has the following beneficial effects:

(1) Distribution of the plurality of unmanned total stations 1: the device is equipped with a plurality of unmanned total stations 1 distributed at different heights and positions of the adjustable truss 202 group. Because the total station can carry out measurement in all directions, through the total station of these distributions, the device can acquire the measurement data of foundation ditch different positions simultaneously, including information of horizontal, perpendicular and angular direction.

(2) Annular array arrangement of self-propelled adjusting mechanism 3: the self-propelled adjusting mechanisms 3 are arranged in an annular array, and the distance between the self-propelled adjusting mechanisms 3 and the center of the telescopic truss mechanism 2 is ensured to be equal. When the self-propelled adjusting mechanism 3 performs the stepwise lifting adjustment, the inclination of the telescopic truss mechanism 2 is kept within a preset standard value range. This arrangement ensures that the overall shape and inclination of the pit is properly maintained during the ranging process.

(3) Telescoping design of adjustable truss 202 group: the design of the adjustable truss 202 group enables the telescopic truss frame mechanism 2 to flexibly stretch and retract, and is suitable for foundation pits with different depths and shapes. When the height of the telescopic truss mechanism 2 changes, the total station also follows the change in height. Through the telescopic design, the device can acquire the distance measurement information of the foundation pit at different depths.

(4) Co-operation of the annular arrays: when the self-propelled adjusting mechanism 3 performs the lifting adjustment, the adjustment of the different self-propelled adjusting mechanisms 3 in different directions does not cause the inclination imbalance of the whole telescopic truss mechanism 2 due to the cooperative work of the annular arrays. The method ensures that beneficial space attitude point positions can be maintained in all directions, and is beneficial to accurately detecting the foundation pit spacing information.

The above examples merely illustrate embodiments of the utility model that are specific and detailed for the relevant practical applications, but are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
