Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology characterized by using electrical or magnetic methods, and more specifically, to a split-type dual-probe thickness gauge. Background Technology

[0002] Currently, floor thickness measurement has become an important indicator in quality inspection. Floor slab thickness gauges use electromagnetic wave methods to perform non-destructive testing of floor slab thickness. This method has high measurement accuracy, does not require drilling and does not cause damage to the building structure, and is widely used. The thickness value measured when the center points of the transmitting and receiving probes of the floor slab thickness gauge coincide is the thickness value of the floor slab.

[0003] After searching, it was found that application number CN202021922427.4, entitled "A Floor Slab Thickness Gauge," addresses the problem that during long-term testing, it is impossible to ensure that the testing personnel on the ground floor remain stationary, and their movement affects testing efficiency. This application addresses the issue by using a ball-head spring plunger at the bottom of the telescopic rod to engage with a locking hole in the support base, thereby improving the stability of the connection between the telescopic rod and the support base and reducing the probability of the telescopic rod detaching from the support base. By installing the bottom end of the telescopic rod into the mounting groove of the support base, the telescopic rod is fixed to the support base and perpendicular to the ground. The testing personnel on the ground floor do not need to support the telescopic rod for a long time, reducing the probability of the transmitting probe moving and affecting the test results, thus improving testing efficiency. However, in practical use, although this application solves the problems of probe movement affecting test results and the need to hold the probe for a long time, the installation of the probe on the top surface of the floor slab still requires the staff to bend over to place the probe and hold the thickness gauge by hand, which is still quite cumbersome. The movement of the probe located below the floor slab still relies on manual handling, which is also cumbersome and not labor-saving enough. Further improvements are needed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a split-type dual-probe thickness gauge, which is more convenient to use and thus solves the problems mentioned in the background.

[0006] (II) Technical Solution To achieve the aforementioned advantages of greater ease of use, the specific technical solution adopted by this utility model is as follows: The split-type dual-probe thickness gauge includes a movable frame and a trolley. The top surface of the movable frame has a rod hole, through which a support rod is connected. A groove is fixedly installed on the top surface of the support rod, and the thickness gauge body is fixedly connected to the groove by a handle bolt. A transmitting probe is fixedly installed on the bottom surface of the support rod. Casters are installed on the bottom surface of the movable frame. A telescopic rod is fixedly installed on the top surface of the trolley, and a support frame is arranged above the telescopic rod. A receiving probe is fixedly installed on the top surface of the support frame. A stop bar is fixedly installed on the surface of the support rod. A rod groove is opened on the top surface of the movable frame, and one end of the rod groove is connected to the rod hole.

[0007] Furthermore, a tray is fixedly installed on the top surface of the telescopic rod, and a guide rod is fixedly installed on the bottom surface of the support frame. The guide rod passes through the tray and is slidably connected to the tray. A spring is sleeved on the outer side of the guide rod between the tray and the bottom surface of the support frame.

[0008] Furthermore, the two ends of the spring are fixedly connected to the top surface of the tray and the bottom surface of the support frame, respectively.

[0009] Furthermore, the telescopic rod has a self-locking structure, and the maximum extension length of the telescopic rod is greater than the floor height.

[0010] Furthermore, the bottom of the trolley is also fixedly equipped with casters, and the casters have a self-locking structure.

[0011] Furthermore, the handle bolts pass through the bracket and are threadedly connected to the bracket, and multiple sets of handle bolts are arranged.

[0012] Furthermore, multiple sets of the guide rods and springs are arranged.

[0013] Furthermore, the height of the trolley handle is not less than 1 meter.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a split-type dual-probe thickness gauge, which has the following advantages: (1) This utility model adopts a movable frame and a tray. When measuring the thickness of the floor slab, the movable frame can be placed above the floor slab and the trolley can be placed below the floor slab. The staff can push the support rod to move the movable frame, which eliminates the trouble of carrying the transmitting probe by hand and improves the convenience of movement. At the same time, when lowering the transmitting probe, it is only necessary to rotate the support rod until the stop bar is aligned with the rod groove so that the stop bar can pass through the rod groove and the transmitting probe can be lowered to abut against the top surface of the floor slab. The top of the support rod supports the thickness gauge body through the tray, which is convenient for the staff to observe and use. It eliminates the problem of the traditional transmitting probe requiring the staff to bend over to place it, which significantly improves the convenience of use.

[0015] (2) This utility model adopts a trolley. After the transmitting probe is placed, the staff can push the trolley to move the receiving probe to below the transmitting probe. Then, by extending the telescopic rod, the receiving probe is brought into contact with the bottom surface of the floor slab, and the floor thickness can be detected. The trolley is convenient for the staff to push and move, which further improves the convenience of use. After the test is completed, the staff can also place the mobile frame on the top of the trolley for storage, which greatly facilitates the staff to move and use. Attached Figure Description

[0020] According to an embodiment of this utility model, a split-type dual-probe thickness gauge is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4As shown, the split-type dual-probe thickness gauge according to an embodiment of this utility model includes a movable frame 1 and a trolley 9. The top surface of the movable frame 1 has a rod hole 17, through which a support rod 3 is connected. A groove 4 is fixedly installed on the top surface of the support rod 3, and the thickness gauge body 5 is fixedly connected inside the groove 4 via a handle bolt 6. The thickness gauge body 5, the transmitting probe 2, and the receiving probe 11 are a complete set of equipment. The transmitting probe 2 is fixedly installed on the bottom surface of the support rod 3. A caster wheel 8 is installed on the bottom surface of the movable frame 1. A telescopic rod 10 is fixedly installed on the top surface of the trolley 9, and a support frame 12 is arranged above the telescopic rod 10. The receiving probe 11 is fixedly installed on the top surface of the support frame 12. A stop bar 7 is fixedly installed on the surface of the support rod 3. A rod groove 16 is opened on the top surface of the movable frame 1, and one end of the rod groove 16 is connected through the rod hole 17. When measuring the thickness of a floor slab, the movable frame 1 can be placed above the floor slab, and the trolley 9 below the floor slab. The operator can push the support rod 3 to move the movable frame. The mobile frame 1 eliminates the hassle of carrying the transmitting probe 2 by hand, improving the convenience of movement. When lowering the transmitting probe 2, simply rotate the support rod 3 until the stop bar 7 aligns with the rod groove 16, allowing the stop bar 7 to pass through the rod groove 16 and lower the transmitting probe 2 to abut against the top surface of the floor slab. The top of the support rod 3 supports the thickness gauge body 5 via the bracket 4, facilitating observation and use by staff. This eliminates the need for staff to bend over to place the traditional transmitting probe 2, significantly improving usability. After the transmitting probe 2 is placed, staff can push the trolley 9 to move the receiving probe 11 below the transmitting probe 2. Then, by extending the telescopic rod 10, the receiving probe 11 can abut against the bottom surface of the floor slab for floor thickness measurement. The trolley 9 facilitates movement by staff, further improving usability. After the measurement is complete, staff can also place the mobile frame 1 on top of the trolley 9 for storage, greatly facilitating handling and use.

[0022] In one embodiment, a tray 14 is fixedly installed on the top surface of the telescopic rod 10, and a guide rod 15 is fixedly installed on the bottom surface of the support frame 12. The guide rod 15 passes through the tray 14 and is slidably connected to the tray 14. A spring 13 is sleeved on the outer side of the guide rod 15 between the tray 14 and the bottom surface of the support frame 12. The two ends of the spring 13 are fixedly connected to the top surface of the tray 14 and the bottom surface of the support frame 12, respectively, to prevent the support frame 12 from falling. Multiple sets of guide rods 15 and springs 13 are arranged to improve the stability of the guide. During the adjustment of the telescopic rod 10, the receiving probe 11 presses against the bottom surface of the floor slab, and the spring 13 is compressed to provide pressure, thereby improving the stability of the receiving probe 11 in contact with the floor slab.

[0023] In one embodiment, the telescopic rod 10 has a self-locking structure, and the maximum extension length of the telescopic rod 10 is greater than the floor height, ensuring that the receiving probe 11 can abut against the bottom surface of the floor slab.

[0024] In one embodiment, the bottom surface of the trolley 9 is also fixedly equipped with casters 8, and the casters 8 have a self-locking structure, which makes it convenient to lock and fix the device in place.

[0025] In one embodiment, the handle bolt 6 passes through the bracket 4 and is threadedly connected to the bracket 4, and multiple sets of handle bolts 6 are arranged to facilitate tightening and fixing of the thickness gauge body 5.

[0026] In one embodiment, the handle of the trolley 9 is at least 1 meter high to facilitate pushing and using.

[0027] Working principle: When measuring the thickness of a floor slab, the mobile frame 1 can be placed above the floor slab, and the trolley 9 below it. Workers can push the support rod 3 to move the mobile frame 1, eliminating the need to manually carry the transmitting probe 2 and improving ease of movement. When lowering the transmitting probe 2, simply rotate the support rod 3 until the stop bar 7 aligns with the bar groove 16, allowing the stop bar 7 to pass through the groove 16 and lower the transmitting probe 2 to contact the top surface of the floor slab. The top of the support rod 3 supports the thickness gauge body 5 via the bracket 4, facilitating observation and use by workers. This eliminates the need for workers to bend over to place the transmitting probe 2, significantly improving usability. After the transmitting probe 2 is in place, workers can push the trolley 9 to move the receiving probe 11 below it. Then, by extending the telescopic rod 10, the receiving probe 11 contacts the bottom surface of the floor slab, allowing for floor thickness measurement. The trolley 9 facilitates movement and further enhances usability. After the measurement is complete, workers can also place the mobile frame 1 on top of the trolley 9 for storage, greatly facilitating handling and use.
