Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a foundation crack measuring device. Background Technology

[0002] A foundation crack measuring device is an instrument or system used to detect, record, and analyze changes in cracks in foundations or building structures. It is mainly used to monitor the width, length, depth, direction, and development trend of cracks in order to assess structural safety and stability.

[0003] In the existing technology, foundation crack measurement devices usually use photography to calculate crack width or length, which has low measurement accuracy. In addition, due to the complex and variable environment in which foundation crack measurement devices are used, existing fixed-form foundation crack measurement devices can no longer eliminate the influence of the environment on the measurement data, further reducing the accuracy of the measurement data. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a foundation crack measuring device with higher measurement accuracy and higher measurement data accuracy.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A foundation crack measuring device, comprising:

[0007] The detection device includes a laser probe, a telescopic rod, a base, and a data processor connected sequentially along the height direction;

[0008] A support frame includes multiple movable support rods, which are rotatably connected to a base to adjust the angle between the movable support rods and the base to change the height of the base; the multiple movable support rods form a working space, and the laser probe and the telescopic rod are disposed within the working space;

[0009] Multiple linkage rods are distributed circumferentially around the laser probe. The movable support rod and the laser probe are both linked to the linkage rods, and at least one of them is hinged to the linkage rod, so that the laser probe can be raised and lowered in conjunction with the movable support rod.

[0010] Furthermore, the movable support rod includes a fixed rod and a sliding rod; the top end of the fixed rod is connected to the base to support the base; one of the sliding rod and the fixed rod is provided with a rod guide groove, and the other is provided with a guide block; the rod guide groove extends along the extension direction of the sliding rod, and the guide block slides in cooperation with the rod guide groove; the bottom of the sliding rod is used to support the ground.

[0011] Furthermore, the movable support rod is provided with a sliding locking member, and the sliding locking member has a rod receiving space. The sliding rod and the fixed rod are arranged in a cooperating state in the rod receiving space. The sliding locking member can slide along the extension direction of the sliding rod and can lock the sliding rod to the fixed rod.

[0012] Furthermore, the sliding locking member is provided with threads, and a fastener is connected to the threads. The fastener is used to extend into the rod receiving space, so that the inner wall of the sliding locking member is pressed against the outer wall of the sliding rod and the fixed rod.

[0013] Furthermore, the linkage rod is hinged to the sliding locking member.

[0014] Furthermore, the end of the sliding rod used for ground support is provided with anti-slip studs.

[0015] Furthermore, the base has a first hole, and the top end of the telescopic rod passes through the first hole and connects to the data processor.

[0016] Furthermore, the telescopic rod has a tubular structure to form a cable accommodating space inside, and a second hole is opened at the top of the telescopic rod. The first hole and the second hole are connected to form a cable threading hole.

[0017] Furthermore, the base is provided with a circular guide groove, and the data processor is provided with multiple sliders. The sliders cooperate with the circular guide groove to make the circular guide groove rotatably connected to the base.

[0018] Furthermore, the data processor is equipped with a photovoltaic panel.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The detection device includes a laser probe, a telescopic rod, a base, and a data processor connected sequentially along the height direction. This allows the telescopic rod to change the distance between the laser probe and the data processor, thus enabling the laser probe to get closer to the foundation crack to be measured and obtain more accurate measurement data.

[0021] 2. The support frame includes multiple movable support rods, which are rotatably connected to the base to adjust the angle between the movable support rods and the base, thereby changing the height of the base. The multiple movable support rods form a working space, within which the laser probe and the telescopic rod are disposed. Clearly, the volume of the working space can dynamically change due to the opening angle of the movable support rods. The laser probe is located within the working space and connected to the base, thus being supported by the movable support rods. Furthermore, the laser probe is also protected by the movable support rods during operation.

[0022] 3. Multiple linkage rods are distributed circumferentially around the laser probe. The movable support rod and the laser probe are both linked to the linkage rods, and at least one of them is hinged to the linkage rod, so that the laser probe can be raised and lowered in conjunction with the movable support rod. Preferably, both ends of the linkage rod are hinged to the laser probe and the movable support rod, respectively. In this way, when the user adjusts the opening angle of the movable support rod, the laser probe can also rise and fall with the movable support rod, which not only allows the laser probe to be closer to the measurement target, but also makes the overall structure more flexible and compact.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] See Figures 1-4 A preferred embodiment of the present invention provides a foundation crack measuring device, comprising: a detection device 1, a support frame 2, and multiple linkage rods 203;

[0032] The detection device 1 includes a laser probe 101, a telescopic rod 102, a base 104, and a data processor 103 connected sequentially along the height direction. Obviously, the telescopic rod 102 can change the distance between the laser probe 101 and the data processor 103, so that the laser probe 101 can be closer to the foundation crack to be measured, and more accurate measurement data can be obtained.

[0033] The support frame 2 includes multiple movable support rods 201, which are rotatably connected to the base 104 to adjust the angle between the movable support rods 201 and the base 104, thereby changing the height of the base 104. The multiple movable support rods 201 form a working space 202, within which the laser probe 101 and the telescopic rod 102 are disposed. Obviously, the volume of the working space 202 can dynamically change due to the opening angle of the movable support rods 201. The laser probe 101 is located within the working space 202 and connected to the base 104, so that the laser probe 101 is supported by the movable support rods 201. In addition, the laser probe 101 is also protected by the movable support rods 201 during operation.

[0034] Multiple linkage rods 203 are distributed circumferentially around the laser probe 101. The movable support rod 201 and the laser probe 101 are both linked to the linkage rods 203, and at least one of them is hinged to the linkage rod 203, so that the laser probe 101 can be raised and lowered in conjunction with the movable support rod 201. Preferably, both ends of the linkage rod 203 are hinged to the laser probe 101 and the movable support rod 201, respectively. In this way, when the user adjusts the opening angle of the movable support rod 201, the laser probe 101 can also be raised and lowered with the movable support rod 201, which not only allows the laser probe 101 to be closer to the measurement target, but also makes the overall structure more flexible and compact.

[0035] In use, first open the movable support rod 201 to a suitable angle to form a sufficient working space 202. After aligning the laser probe 101 with the foundation crack to be measured, place the support frame 2 on the ground to stabilize the overall structure. Then, raise and lower the telescopic rod 102 to bring the laser probe 101 as close as possible to the foundation crack to be measured. Then, start the laser probe 101 and the data processor 103. After a period of time, observe the data processor 103 and record the data.

[0036] Obviously, the detection device 1 includes a laser probe 101, a telescopic rod 102, a base 104, and a data processor 103 connected sequentially along the height direction. This allows the horizontal height of the laser probe 101 to be adjusted via the telescopic rod 102 to match the required measurement height, thereby improving the accuracy of the measurement data. This also makes the signal transmission between the laser probe 101 and the data processor 103 more stable. The support frame 2 includes multiple movable support rods 201, which are rotatably connected to the base 104. This allows the angle between the movable support rods 201 and the base 104 to be adjusted, thus changing the height of the base 104. The multiple movable support rods 201 form a working space 202, within which the laser probe 101 and the telescopic rod 102 are positioned. This ensures that the laser probe 101 is within a safe working space 202 and its horizontal height can be adjusted to match the required measurement height, thereby improving the accuracy of the measurement data. Based on the circumferentially spaced distribution of multiple linkage rods 203 around the laser probe 101, both the movable support rod 201 and the laser probe 101 are linked to the linkage rods 203, and at least one of them is hinged to the linkage rod 203, so that the laser probe 101 can be raised and lowered in conjunction with the movable support rod 201. Thus, as the angle between the movable support rod 201 and the base 104 changes, the height of the base 104 changes accordingly, which in turn causes changes in the height and tilt angle of the linkage rod 203, thereby driving the laser probe 101 to rise and fall. This adjustment method is quick, simple, and efficient, ultimately improving the accuracy of measurement data.

[0037] Preferably, the movable support rod 201 includes a fixed rod 204 and a sliding rod 205; the top end of the fixed rod 204 is connected to the base 104 to support the base 104; one of the sliding rod 205 and the fixed rod 204 is provided with a rod guide groove 206, and the other is provided with a guide block; the rod guide groove 206 extends along the extension direction of the sliding rod 205, and the guide block slides in cooperation with the rod guide groove 206; the bottom of the sliding rod 205 is used to support the ground; obviously, through the cooperation of the rod guide groove 206 and the guide block, the fixed rod 204 and the sliding rod 205 can slide relative to each other to lengthen the movable support rod 201, so that the movable support rod 201 encloses a larger working space 202, thereby reducing the mutual interference between the laser probe 101 and the usage environment.

[0038] Preferably, the movable support rod 201 is provided with a sliding locking member 3, and the sliding locking member 3 is provided with a rod receiving space 301. The sliding rod 205 and the fixed rod 204 are arranged in a cooperating state in the rod receiving space 301. The sliding locking member 3 can slide along the extension direction of the sliding rod 205 and can lock the sliding rod 205 to the fixed rod 204. Obviously, the sliding locking member 3 can slide with the laser probe 101 as it rises and falls, and at the same time can limit the rise and fall of the laser probe 101 to prevent the laser probe 101 from falling out of the working space 202.

[0039] Preferably, the sliding locking member 3 is provided with threads, and a fastener 4 is connected to the threads. The fastener 4 is used to extend into the rod receiving space 301, so that the inner wall of the sliding locking member 3 is pressed against the outer walls of the sliding rod 205 and the fixed rod 204. Obviously, extending the fastener 4 into the rod receiving space 301 can not only increase the friction between the inner wall of the sliding locking member 3 and the outer wall of the sliding rod 205 and the fixed rod 204, but also make the fit between the rod guide groove 206 and the guide block tighter. Through the friction and the fit between the rod guide groove 206 and the guide block, the sliding locking member 3 is locked.

[0040] Preferably, the linkage rod 203 is hinged to the sliding locking member 3; obviously, this arrangement allows the laser probe 101 to be raised and lowered without changing the opening angle of the movable support rod 201, making the overall structure more flexible and more convenient to use.

[0041] Preferably, the end of the sliding rod 205 used for supporting the ground is provided with anti-slip nails 5. Obviously, providing anti-slip nails 5 can increase the friction between the support frame 2 and the ground and prevent the support frame 2 from slipping.

[0042] Preferably, the base 104 has a first hole 207, and the top end of the telescopic rod 102 passes through the first hole 207 and is connected to the data processor 103, so that the data processor 103 is supported by the telescopic rod 102.

[0043] Preferably, the telescopic rod 102 is a tubular structure to form a cable accommodating space 107 inside. The top end of the telescopic rod 102 has a second hole 209, which is connected to the first hole 207 to form a cable threading hole. Obviously, the laser probe 101 and the data processor 103 are electrically connected. Setting the cable accommodating space 107 inside the telescopic rod 102 makes the overall structure more aesthetically pleasing and saves space. In addition, the telescopic rod 102 also protects the cable, giving it a longer service life.

[0044] Preferably, the base 104 is provided with a circular guide groove 208, and the data processor 103 is provided with a plurality of sliders 106. The sliders 106 cooperate with the circular guide groove 208 to make the circular guide groove 208 rotatably connected to the base 104. Obviously, this arrangement facilitates user operation and observation.

[0045] Preferably, the data processor 103 is provided with a photovoltaic panel 105; obviously, the photovoltaic panel 105 can provide power to the laser probe 101 and the data processor 103.

[0046] In use, first open the movable support rod 201 to a suitable angle, align the laser probe 101 with the crack to be measured, and then place the support frame 2 on the ground, ensuring the anti-slip nails 5 are in contact with the ground to stabilize the overall structure. Then, unlock the sliding locking member 3, slide the sliding rod 205, and adjust the length of the movable support rod 201 to form sufficient working space 202. Raise and lower the telescopic rod 102 to bring the laser probe 101 as close as possible to the crack to be measured, tighten the fastener 4 to lock the sliding locking member 3, and then start the laser probe 101 and the data processor 103. The user can rotate the data processor 103 to observe the data according to their own needs.

[0047] Compared with the prior art, the advantages of this utility model are that it adopts a more accurate laser triangulation measurement technology; in addition, users can adjust this utility model to a suitable form according to different usage environments, thereby eliminating the influence of the environment on the measurement process and improving the accuracy of measurement data.
