Description

Technical Field

[0001] This invention relates to the field of highway tunnel detection technology, specifically to a special support for highway tunnel geological detection radar. Background Technology

[0002] With the development of highway tunnel technology, the geological conditions encountered during tunnel construction are becoming increasingly complex. To ensure the safety of highway tunnel construction, it is necessary to detect the geological environment of the tunnel, thereby guaranteeing project safety and saving on tunnel engineering investment. Ground-penetrating radar (GPR) has been widely used in highway tunnel geological exploration due to its fast scanning speed, ease of operation, light weight, high resolution, good shielding effect, and intuitive display.

[0003] For example, Chinese invention patent No. 201610607231.8 provides a geological radar detection auxiliary device for railway tunnels, which can also be applied to geological detection of highway tunnels. Compared with manual operation, mechanical operation makes it easier to control the uniform movement of the radar antenna, thereby avoiding detection errors caused by the uneven movement of the radar antenna by manual hand-held operation, and improving the efficiency of detection and the accuracy of prediction.

[0004] However, traditional highway tunnel detection auxiliary devices or radar mounting brackets still have certain drawbacks when used. When existing geological exploration radar brackets are used in tunnels, although the radar can be controlled to move horizontally without the need for staff to manually move the radar, they cannot guarantee that the radar's movable range can be adjusted when used in tunnels of different widths, thus reducing its applicability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a dedicated support for geological exploration radar in highway tunnels. This solves the technical problem mentioned in the background section: while existing geological exploration radar supports can control the radar's translation and eliminate the need for manual movement by staff, they cannot guarantee the adjustment of the radar's movable range when used in tunnels of different widths, thus reducing their applicability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a special bracket for a highway tunnel geological exploration radar, used for mounting on a detection vehicle to conduct geological exploration of highway tunnels, comprising:

[0007] Mounting plate, wherein a mounting bracket is provided on the mounting plate;

[0008] Two sets of pulleys are provided, each rotatably mounted on the mounting frame along its axis, and the two sets of pulleys are connected by a drive belt.

[0009] An opening and closing mechanism is provided on the mounting frame and connected to two sets of pulleys to drive the two sets of pulleys to open and close in opposite directions;

[0010] A tensioning mechanism is disposed on the mounting plate and connected to the drive belt to tension the drive belt; and

[0011] Mounting components are provided on the drive belt for mounting the detection radar.

[0012] Furthermore, a lifting component is provided at the bottom of the mounting plate, which drives the mounting plate to rise and fall.

[0013] Furthermore, the lifting component includes:

[0014] A base plate, fixed to the probe vehicle, and a mounting plate that can be raised and lowered is mounted on the base plate; and

[0015] A telescopic rod is installed on the base plate, and its telescopic end is fixedly connected to the mounting plate.

[0016] Furthermore, the opening and closing mechanism includes:

[0017] The lifting seat is mounted on the mounting frame in a height-adjustable manner;

[0018] A drive assembly is disposed on the mounting frame and connected to the lifting seat to drive the lifting seat to move up and down along the mounting frame;

[0019] The mounting frame has two sets of pulleys, both sets of which are rotatably mounted on the mounting frame. One set of the mounting frame has a drive motor, the output shaft of which is connected to one set of pulleys.

[0020] A linkage assembly is disposed on the lifting seat and connected to the two sets of mounting frames to drive the two sets of mounting frames to open and close during the lifting of the lifting seat.

[0021] Furthermore, the driving component includes:

[0022] A lead screw, rotatably mounted on the mounting bracket along its axis, and a lifting seat sleeved on and screwed to the lead screw; and

[0023] A drive motor is mounted on the mounting bracket, and its output shaft is connected to the lead screw to drive the lead screw to rotate.

[0024] Furthermore, the connecting rod assembly includes two sets of connecting rod units symmetrically arranged along the axis of the lead screw, and each connecting rod unit includes:

[0025] Two sets of first connecting rods are arranged parallel to each other at intervals, with one end of the first connecting rod hinged to the lifting seat and the other end hinged to the mounting frame; and

[0026] The second connecting rod has one end hinged to the top of the mounting frame and the other end hinged to the first connecting rod. The hinge point between the first connecting rod and the mounting frame is not lower than the hinge point between the second connecting rod and the mounting frame.

[0027] Furthermore, a protective shell is provided on the mounting frame, and the pulley is disposed inside the protective shell.

[0028] Furthermore, the tensioning mechanism includes:

[0029] The first frame is adjustable and mounted on the mounting plate;

[0030] The second tensioning frame is height-adjustable and is arranged parallel to the first tensioning frame at a distance. Both the first and second tensioning frames are provided with multiple sets of rotatable tensioning wheels.

[0031] Two sets of guide wheels, each rotatably mounted on the mounting frame, are provided. The transmission belt is sequentially wound around the two sets of guide wheels and multiple sets of tension wheels.

[0032] A fixing plate is mounted on the mounting bracket. The first tensioning frame is connected to the fixing plate by a set of tension springs, and the second tensioning frame is connected to the mounting plate by another set of tension springs.

[0033] Furthermore, the mounting plate is also provided with a fixing component for fixing the positions of the first tension frame and the second tension frame. The fixing component includes a guide rod arranged vertically on the mounting plate. The first tension frame and the second tension frame are each provided with a guide sleeve. The guide sleeve is slidably sleeved on the guide rod. The guide sleeve is provided with a screwed set screw, and the end of the set screw abuts against the guide rod.

[0034] Furthermore, the installation components include:

[0035] A support plate is mounted on the transmission belt and fixedly connected thereto; and

[0036] A bracket is mounted on the support plate.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. This detection bracket is fixed to the detection vehicle during use. Before use, the detection radar is mounted on the drive belt via the mounting components. Controlling the rotation of one set of pulleys, and through the interaction of the two sets of pulleys, drives the drive belt. During this movement, the drive belt causes the mounting components to move laterally, allowing the detection radar to detect the geological conditions of the highway tunnel without manual lifting. Before installing the detection radar, the two sets of pulleys can be opened and closed via an opening and closing mechanism to accommodate tunnels of different widths. A tensioning mechanism then tensions the drive belt before finally installing the radar. This allows the detection radar to detect the geological conditions of the highway tunnel over a maximum area, adapting to tunnels of varying widths and improving detection efficiency.

[0039] 2. During the opening and closing of the two sets of pulleys controlled by the opening and closing mechanism, the first and second tensioning frames are raised and lowered in opposite directions by the cooperation of the transmission belt and multiple tensioning pulleys. Under the action of two sets of tension springs, a tension force opposite to the direction of movement is applied to the first and second tensioning frames, thereby tensioning the transmission belt. After the positions of the two sets of pulleys are adjusted, one end of the set screw is rotated to abut against the guide rod, thereby fixing the positions of the first and second tensioning frames. This prevents the transmission belt from deforming due to the gravity of the detection radar during installation. Thus, the translation amount of the detection radar can be precisely controlled by the drive motor when controlling the transmission belt, thereby improving the detection accuracy.

[0051] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0052] Example:

[0053] like Figure 1 , 4 As shown, the present invention provides a special bracket for a geological detection radar for highway tunnels, which is used to be installed on a detection vehicle for geological detection of highway tunnels. It includes a mounting plate 101, a mounting frame 102 on the mounting plate 101, two sets of rotatable pulleys 205 on the mounting frame 102, the two sets of pulleys 205 being connected by a transmission belt 401, and a mounting assembly for mounting the detection radar on the transmission belt 401. The mounting assembly includes a support plate 402 fixedly connected to the transmission belt 401, and a bracket 403 on the support plate 402.

[0054] In use, the detection radar can be placed on the support plate 402 and connected to the support bracket 403 with bolts to complete the installation. In some embodiments, it is understood that the installation method of the detection radar is not limited to bolt fixing; it can also be installed using other fixing structures such as compatible clips, which will not be elaborated upon here. After the detection radar is installed, one set of pulleys 205 can be controlled to rotate, thereby driving the transmission belt 401 through the cooperation of the two sets of pulleys 205. During the movement of the transmission belt 401, the support plate 402 can be moved horizontally, thus driving the detection radar to detect different locations within the highway tunnel.

[0055] like Figure 1 As shown, in this embodiment, a lifting assembly is also provided at the bottom of the mounting plate 101. The lifting assembly drives the mounting plate 101 to rise and fall. The lifting assembly includes a base plate 501 fixed on the detection vehicle. The mounting plate 101 is movably mounted on the base plate 501. A telescopic rod 502 is provided on the base plate 501, and the telescopic end of the telescopic rod 502 is fixedly connected to the mounting plate 101. By controlling the extension and retraction of the telescopic rod 502, the mounting plate 101 can be raised and lowered, thereby controlling the rise and fall of the detection radar to detect tunnels at different heights.

[0056] like Figure 1 , 2 As shown, in this embodiment, the mounting frame 102 is provided with an opening and closing mechanism connected to two sets of pulleys 205. The opening and closing mechanism drives the two sets of pulleys 205 to move in opposite directions to open and close. The opening and closing mechanism includes a lifting seat 103 that can be raised and lowered and is provided on the mounting frame 102. The mounting frame 102 is provided with a drive assembly connected to the lifting seat 103. The drive assembly drives the lifting seat 103 to rise and fall along the mounting frame 102. The drive assembly includes a lead screw 104 that can be rotatably provided on the mounting frame 102 along its axis. The lifting seat 103 is sleeved on the lead screw 104 and screwed to it. The mounting frame 102 is provided with a drive motor 105. The output shaft of the drive motor 105 is connected to the lead screw 104 to drive the lead screw 104 to rotate.

[0057] The drive motor 105 can be controlled to drive the lead screw 104 to rotate on the mounting frame 102. During the rotation of the lead screw 104, the lifting seat 103 is raised and lowered through the screw connection with the lifting seat 103. The opening and closing mechanism also includes two sets of mounting frames 203, and two sets of pulleys 205 are rotatably mounted on the mounting frames 203. One set of mounting frames 203 is equipped with a drive motor 206, and the output shaft of the drive motor 206 is connected to one set of pulleys 205. The lifting seat 103 is equipped with a connecting rod assembly that connects to the two sets of mounting frames 203, so as to drive the two sets of mounting frames 203 to open and close during the raising and lowering of the lifting seat 103.

[0058] The linkage assembly includes two sets of linkage units symmetrically arranged along the axis of the lead screw 104. Each linkage unit includes two sets of first linkages 201 and one set of second linkages 202. The two sets of first linkages 201 are arranged parallel to each other at intervals. One end of the first linkage 201 is hinged to the lifting seat 103 and the other end is hinged to the mounting frame 203. One end of the second linkage 202 is hinged to the top of the mounting bracket 102 and the other end is hinged to the first linkage 201.

[0059] The drive motor 206 can control the rotation of one set of pulleys 205, thereby driving the transmission belt 401. During the lifting process, the lifting seat 103 drives one end of the two sets of first connecting rods 201 to rise and fall. Since the two sets of first connecting rods 201, the lifting seat 103, and the mounting frame 203 form a parallelogram structure, and the first connecting rods 201 and the second connecting rods 202 form a multi-link structure, the lifting seat 103 can be controlled to move the mounting frame 203, thereby controlling the opening and closing of the two sets of pulleys 205 through the cooperation of the two sets of connecting rod units, thus adapting to the detection of tunnels of different widths. The hinge point between the first connecting rod 201 and the mounting frame 203 is not lower than the hinge point between the second connecting rod 202 and the mounting bracket 102, mainly to ensure that the detection radar is at the highest point and to avoid the structure of the bracket affecting the operation of the detection radar.

[0060] like Figure 1 , 2 As shown, in this embodiment, a protective shell 204 is provided on the mounting frame 203, and the pulley 205 is disposed inside the protective shell 204. The protective shell 204 protects the pulley 205 from collision with the tunnel wall, and at the same time limits the movement range of the support plate 402, preventing the detection radar on the support plate 402 from hitting the tunnel wall, thus improving the practical value of the bracket.

[0061] like Figures 1 to 3 As shown, in this embodiment, the mounting plate 101 is also provided with a tensioning mechanism connected to the transmission belt 401, which tensions the transmission belt 401. The tensioning mechanism includes a first tensioning frame 301 and a second tensioning frame 302 that are liftable and arranged on the mounting plate 101. The second tensioning frame 302 is arranged parallel to the first tensioning frame 301 at intervals. Both the first tensioning frame 301 and the second tensioning frame 302 are provided with multiple sets of rotatable tensioning wheels 303. The mounting frame 102 is rotatably provided with two sets of guide wheels 107. The transmission belt 401 is wound around the two sets of guide wheels 107 and the multiple sets of tensioning wheels 303 in sequence. The mounting frame 102 is also provided with a fixing plate 106. The first tensioning frame 301 is connected to the fixing plate 106 by a set of tension springs 307, and the second tensioning frame 302 is connected to the mounting plate 101 by another set of tension springs 307.

[0062] During the opening and closing process of the two sets of pulleys 205 controlled by the opening and closing mechanism, the first tension frame 301 and the second tension frame 302 are pulled by the cooperation of the transmission belt 401 and multiple tensioning pulleys 303. Under the action of the two sets of tension springs 307, the first tension frame 301 and the second tension frame 302 are subjected to a pulling force with opposite directions of movement to tension the transmission belt 401, so that the movement of the pulleys 205 can stably control the movement of the transmission belt 401.

[0063] Furthermore, a fixing component is provided on the mounting plate 101 for fixing the positions of the first tension frame 301 and the second tension frame 302. The fixing component includes a guide rod 306 arranged vertically on the mounting plate 101. A guide sleeve 304 is provided on both the first tension frame 301 and the second tension frame 302. The guide sleeve 304 is slidably sleeved on the guide rod 306. A screwed set screw 305 is provided on the guide sleeve 304. The end of the set screw 305 abuts against the guide rod 306.

[0064] After the transmission belt 401 is tensioned, the position of the first tensioning frame 301 and the second tensioning frame 302 can be fixed by rotating the set screw 305 so that one end is aligned with the guide rod 306. Then the detection radar is installed to avoid the weight of the detection radar causing deformation of the transmission belt 401, thus improving the accuracy of the detection process.

[0065] Specific usage and beneficial effects of the present invention:

[0066] When in use, the mounting bracket 102 is fixed on the detection vehicle. Before use, the detection radar is mounted on the transmission belt 401 via the support plate 402. The rotation of one set of pulleys 205 can be controlled, and the transmission belt 401 can be driven to move through the cooperation of the two sets of pulleys 205. During the movement of the transmission belt 401, the support plate 402 can be moved laterally, so that the detection radar can move to detect the geology of the highway tunnel without the need for manual lifting and moving of the detection radar. Before installing the detection radar, the drive motor 105 can control the screw 104 to rotate. The screw 104 and the lifting seat 103 are connected by a screw to drive the lifting seat 103 to rise and fall. During the rising and falling process, the lifting seat 103 drives the two sets of mounting frames 203 to move in opposite directions through the cooperation of the first connecting rod 201 and the second connecting rod 202, thereby controlling the opening and closing of the two sets of pulleys 205 to adapt to tunnels of different widths. Then, the transmission belt 401 is tensioned by the tensioning mechanism. Finally, the radar is installed, which enables the detection radar to detect the geology of highway tunnels over the largest range and adapt to tunnels of different widths, thus improving the detection efficiency.

[0067] During the opening and closing of the two sets of pulleys 205 controlled by the opening and closing mechanism, the first tension frame 301 and the second tension frame 302 are raised and lowered in opposite directions by the cooperation of the transmission belt 401 and multiple tensioning pulleys 303. Under the action of the two sets of tension springs 307, a tension force opposite to the direction of movement is applied to the first tension frame 301 and the second tension frame 302, thereby tensioning the transmission belt 401. After the positions of the two sets of pulleys 205 are adjusted, the set screw 305 is rotated so that one end abuts against the guide rod 306, thereby fixing the positions of the first tension frame 301 and the second tension frame 302. This prevents the transmission belt 401 from deforming due to the gravity of the detection radar during installation. Thus, the translation amount of the detection radar can be precisely controlled by the drive motor 206 when controlling the transmission belt 401, thereby improving the detection accuracy.

[0068] Furthermore, after use, the support can be lowered to the lowest point by controlling the rotation of the lead screw 104, so that the first connecting rod 201 and the second connecting rod 202 can be retracted, and the two sets of pulleys 205 can be retracted, thereby storing the support, greatly reducing the space occupied by the support, facilitating the transportation and installation of the support, and improving the practicality of the support.

[0069] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
