[0026] As mentioned in the background technology, the drilling or crushing equipment commonly used in rock and soil sampling in the prior art includes the following: rotary drill, impact drill and handheld electric drill. These equipment usually require the operator and the equipment to be in the place to be constructed and surveyed at the same time. When the geological conditions of the place to be constructed and surveyed are unclear or there are safety hazards, the operator cannot enter the place to be constructed and surveyed. At this time, the existing equipment is difficult to perform the construction survey or rock and soil sampling functions. The bridge construction survey device of the present invention will be introduced in detail in conjunction with the accompanying drawings.

[0027] Explanation of the reference numerals: vehicle body 1, rear wheel 2, first electric push rod 3, wheel-side motor 4, climbing wheel 5, drill bit 6, support ring 7, first motor 8, camera 9, mounting rod 10, controller 11, manipulator 12, receiving slot 13, sample storage box 14, support plate 15, carrier plate 16, second electric push rod 17, hinged support 18.

[0028] See also Figure 1-7 As shown, according to an embodiment of the present invention, a bridge construction survey device is provided. The bridge construction survey device comprises: Crushing unit, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes a flippable and foldable carrier plate, a drill bit slidably arranged on the carrier plate, and a first motor driving the drill bit to rotate; the crushing unit also includes a second electric push rod, the bottom of the second electric push rod is hinged to the vehicle body and the top is hinged to one end of the carrier plate, the front end of the receiving groove of the vehicle body is provided with an articulated support, and the other end of the carrier plate is articulated to the articulated support. The main function of the crushing unit is to crush the rock and soil, and to facilitate rock and soil sampling. The second electric push rod can drive the carrier plate, the drill bit, etc. to swing around the articulated support, which can not only adjust the angle of the carrier plate and the drill bit to obtain an angle range that is conducive to rock and soil crushing, but also facilitate the retraction and extension of the carrier plate and the drill bit. The design is ingenious and the conception is novel.

[0029] Car body, such as Figure 1 , Figure 2 , Figure 3 As shown, a receiving groove for receiving the crushing unit is provided in the middle, and traveling wheels and a second motor for driving the traveling wheels are provided at the bottom; the setting of the receiving groove greatly facilitates the placement of the crushing unit, and the setting of the traveling wheels and the second motor improves the mobility of the entire device, and the traveling wheels include front wheels and rear wheels.

[0030] Sampling unit, such as Figure 1 , Figure 2 and Figure 7 As shown, it includes a sample storage box fixed on the vehicle body and a manipulator installed on the vehicle body, and the manipulator can grab the sample crushed by the crushing unit into the sample storage box; the specifications and brands of the manipulator can be selected from common types on the market according to needs, and the sample storage box can be divided into multiple compartments, which is convenient for storing rock and soil samples after multiple sampling; preferably, the sample storage box and the manipulator are both arranged at the rear end of the vehicle body, which is not only conducive to the overall structural balance of the vehicle body, but also leaves sufficient space for the crushing unit at the front end, and can also avoid the sample in the sample storage box from being contaminated during the crushing process.

[0031] Climbing unit, such as Figure 1 , Figure 2 , Figure 5 , Figure 6As shown, it includes two first electric push rods respectively fixed on the carrier plate, and the two first electric push rods are symmetrically distributed on both sides of the drill bit, which is beneficial to the force balance of the entire carrier plate and ensures the working stability of the drill bit. The free end of the first electric push rod is fixed with a wheel-side motor and a climbing wheel driven by the wheel-side motor. The thrust direction of the first electric push rod is parallel to the sliding direction of the drill bit; the wheel-side motor integrates the "power, transmission, and braking" systems into a set of motors, which is directly placed in the hub of the climbing wheel. The setting of the first electric push rod can realize the lifting of the front end of the vehicle body and the front wheel, which greatly improves the passability of the entire device. The principle is described in detail below.

[0032] Control unit, such as Figure 1 , Figure 2 As shown, it includes a camera installed on the vehicle body, a communication module for realizing remote communication, and a controller. The controller is electrically connected to the camera, the communication module, the manipulator, the first motor, the second motor, the first electric push rod, and the wheel-side motor. The setting of the camera can facilitate the operator to observe the surrounding environment and complete the construction survey, and at the same time, it can realize the video and image recording of the geological environment passed by. Preferably, the camera can be set in the middle or front part of the vehicle body to facilitate the observation of the working condition of the drill bit and the road condition. The communication module adopts LORA wireless communication mode. LORA (Long Range Radio) is a low-power wide area network (LPWAN) technology specially designed for long-distance communication of Internet of Things (IoT) devices. It has long-distance transmission and low power consumption characteristics. The communication module realizes the function of the operator remotely giving instructions to the controller or remotely operating the controller.

[0033] In the present invention, by setting up a vehicle body, the mobility and portability of the entire device can be easily realized. At the same time, the greatest feature of the present invention is the innovative design of the carrier plate and climbing wheels, which can not only greatly improve the climbing ability of the entire device, but also use the gravity of the entire vehicle body as the thrust to push the drill bit when the drill bit breaks rock and soil. During the process, the climbing wheel can not only be used to protect the drill bit, but also indirectly control the rock and soil crushing depth and speed. It is particularly important to note that during the entire crushing process, the movement trajectory of the drill bit and the carrier plate has a slight arc, thereby producing an action similar to hole expansion, which greatly improves the crushing effect and efficiency, and is also convenient for the subsequent manipulator to grab rock and soil samples.

[0034] In particular, the entire device can be operated remotely, without the need for operators to go deep into dangerous areas, which greatly improves the efficiency of bridge construction surveys and reduces the difficulty of work.

[0035] For details about the schematic diagram of the principle of the present invention to pass through obstacles or steep slopes, see Figure 5 , Figure 6When the vehicle body reaches an obstacle or a steep slope and cannot go around it, the operator controls the second electric push rod through the controller to adjust the carrier plate and the drill bit to a suitable angle, and then controls the first electric push rod through the controller to push the climbing wheel to contact the high ground until the front end of the vehicle body and the front wheels are lifted and can cross the obstacle or steep slope. The operator continues to control the wheel-side motor and the second motor through the controller to respectively drive the climbing wheel and the rear wheel to move until the rear wheel approaches the obstacle or steep slope. At this time, the operator can control the first electric push rod through the controller to retract until the front wheel descends and contacts the high ground. During this process, the rear wheel will be continuously lifted, and the operator controls the wheel-side motor and the second motor through the controller to respectively drive the climbing wheel and the front wheel to move to pass the obstacle or steep slope.

[0036] In at least one embodiment, the working part of the drill bit extends out of the carrier plate, and the climbing wheel extends out of the carrier plate farther than the drill bit. This has two functions. First, the actual work of the climbing wheel and the drill bit does not interfere with each other. Second, when the second electric push rod is reset or the carrier plate and the drill bit are folded, the climbing wheel can still extend forward of the drill bit, thereby preventing the drill bit from being subjected to collision impact from the front.

[0037] Preferably, at least one-half of the working part of the drill bit extends out of the carrier plate to ensure that the drill bit has sufficient working length. This is a verified optimal value that takes into account the service life, operational stability and effective working distance of the drill bit. In particular, when one-half to two-thirds of the working part of the drill bit extends out of the carrier plate, the comprehensive effect is particularly obvious.

[0038] The radius of the climbing wheel is larger than the diameter of the drill bit. This arrangement can prevent the drill bit from protruding from the climbing wheel in height, thereby better protecting the drill bit.

[0039] In addition, if Figure 1 , Figure 7 As shown, in order to prevent the drill bit cantilever from being too long, a support ring is provided at the front end of the carrier plate for the drill bit to pass through, thereby providing support force without affecting the normal operation of the drill bit.

[0040] In at least one embodiment, a lifting ring (not shown in the figure) is further provided in the middle of the vehicle body to facilitate the use of tools such as a tool rope or a crane in conjunction with the entire device.

[0041] In at least one embodiment, a support plate is provided at the rear end of the accommodating groove, and the support plate can play a role in supporting the carrier plate when the second electric push rod is reset, thereby facilitating the folding of the carrier plate and its placement in daily state.

[0042] The device of the present invention also includes a battery pack to provide power for various components in the entire device. The battery pack is arranged at the bottom of the receiving tank to facilitate lowering the center of gravity of the entire device. Specifically, a rechargeable lithium battery can be used, which is convenient and fast.

[0043] The present invention also provides a method, which is based on the above-mentioned bridge construction survey device and includes the following steps: Step S1, using a tool rope to lower the bridge construction survey device to the location to be surveyed; of course, a small lifting device such as an electric hoist can also be used for lifting and lowering operations; Step S2, the operator controls the second electric push rod through the controller to adjust the carrier plate and the drill bit to a suitable angle, and then controls the first electric push rod through the controller to push the climbing wheel to contact the ground until the front end of the vehicle body is lifted, and the operator controls the wheel side motor and the second motor through the controller to drive the climbing wheel and the walking wheel to move to the sampling location respectively; In step S3, the operator controls the first electric push rod through the controller to drive the climbing wheel to retract, and controls the first motor through the controller to drive the drill bit to rotate. When the drill bit finishes crushing the rock and soil, the operator controls the first electric push rod through the controller to push and extend the climbing wheel until the drill bit is off the ground. The operator controls the first motor through the controller to stop rotating and controls the first electric push rod to drive the climbing wheel to retract until the front running wheel of the vehicle body contacts the ground. The operator controls the second electric push rod to reset through the controller, and controls the manipulator through the controller to grab the rock and soil samples to the sample storage box. Of course, during the process, the operator can control the second motor through the controller to drive the front and rear wheels to adjust the distance between the manipulator and the rock and soil samples, so as to realize the manipulator to quickly grab the rock and soil samples. Step S4, after completing the rock and soil sampling, the operator can retract the bridge construction survey device.

[0044] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein are interpreted accordingly.

[0045] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
