Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to an external wall void detection equipment. Background Art

[0002] For the void detection of building exterior walls, the traditional method is manual knocking, which is both dangerous and inefficient. Later, some detection equipment based on detection platforms emerged. Its principle is to use a sling to lift the detection platform from above the building and perform knocking detection on the exterior wall of the building, greatly improving the safety and efficiency of detection. However, the defects of such equipment at present are as follows:

[0003] The problem of the fit between the detection platform and the exterior wall cannot be solved. When the detection platform moves or the knocking mechanism knocks, there will be a certain distance movement, resulting in inconsistent knocking forces of the knocking mechanism or inconsistent sound wave reception quality of the sensor, and ultimately leading to large errors in the detection results. Content of the Utility Model

[0004] In order to solve the deficiencies in the prior art, the utility model provides an external wall void detection equipment. The external wall void detection equipment is configured with a counterweight close to the working surface and a fixed pulley with sliding positioning, so that the detection trolley can always be close to the wall, ensuring the accuracy of the detection results. At the same time, the adjustable position of the positioning wheel also provides adaptability for detection under more realistic conditions.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides an external wall void detection equipment, including a detection trolley. A wheel is arranged on one side surface of the detection trolley. The side surface of the detection trolley where the wheel is arranged is defined as the working surface. A hammering mechanism and a sound wave receiving sensor are arranged on the working surface of the detection trolley;

[0007] A counterweight and a hook are respectively arranged on a pair of opposite side surfaces of the detection trolley on the working surface. The counterweight is arranged at a position of the detection trolley close to the working surface;

[0008] It also includes a fixed pulley and a winch. The steel cable connected to the winch bypasses the fixed pulley and is connected to the hook. The fixed pulley is arranged on a pulley positioning mechanism, and an adjustment groove with an angle between the length direction and the working surface of the detection trolley is arranged on the pulley positioning mechanism.

[0009] For the external wall void detection device of the present utility model, before operation, according to the position where the pulley positioning mechanism can be installed, adjust the position of the fixed pulley on the pulley positioning mechanism along the adjustment groove, so that after the sling passing around the fixed pulley is connected to the sling ring, it can present a certain angle, so that the sling has a force towards the wall on the detection trolley. The counterweight always provides a downward pulling force at a position close to the working surface of the detection trolley. Therefore, during operation, the detection trolley can always be close to the wall, ensuring the detection quality. At the same time, due to the different situations above the building, in some cases, the installation position of the fixed pulley is not ideal. For example, the position where the fixed pulley can be installed is at a certain distance from the wall. At this time, the traditional fixed-mounted fixed pulley will cause the sling to rub against the corner of the wall. However, with the assistance of the pulley positioning mechanism, the fixed pulley of the present utility model has a certain space for lateral adjustment and can adapt to installations in more situations.

[0010] The external wall void detection device of the present utility model is equipped with a counterweight close to the working surface and a fixed pulley with sliding positioning, enabling the detection trolley to always be close to the wall, ensuring the accuracy of the detection results. At the same time, the adjustable position of the positioning wheel also provides adaptability for detections under more realistic conditions.

[0011] In a further technical solution, a plurality of acoustic wave receiving sensors are provided.

[0012] A plurality of acoustic wave receiving sensors can obtain a plurality of acoustic wave data, and a more accurate detection result can be obtained through the processing of the plurality of acoustic wave data.

[0013] In a further technical solution, the plurality of acoustic wave receiving sensors are arranged around the hammering mechanism.

[0014] The plurality of acoustic wave receiving sensors arranged around can collect acoustic waves from different directions, further ensuring the accuracy of the detection results.

[0015] In a further technical solution, the wheels are universal wheels.

[0016] Using universal wheels as the wheels enables the detection trolley to have the function of lateral movement, expanding the detection range from a line to a surface and making the detection range larger.

[0017] In a further technical solution, both the pulley positioning mechanism and the winch are arranged on a movable carrier.

[0018] Based on the universal wheels on the detection trolley, by arranging the pulley positioning mechanism and the winch on a movable carrier, the movable carrier can be used for lateral movement, realizing the lateral movement of the detection trolley on the external wall, with a large detection range and further improving the detection efficiency.

[0019] In a further technical solution, the pulley positioning mechanism includes a positioning frame, an adjustment groove is formed on the positioning frame, positioning grooves are respectively formed on a pair of opposite side surfaces of the adjustment groove along the length direction of the adjustment groove, both ends of the rotating shaft of the fixed pulley are respectively rotatably connected with positioning blocks, and the shape of the positioning blocks matches the shape of the positioning grooves.

[0020] By moving the positioning blocks in the adjustment groove, the position of the fixed pulley is adjusted, which is convenient for operation, and the installation of the positioning frame itself is also more convenient than the installation of the fixed pulley.

[0021] In a further technical solution, a plurality of positioning holes extending to the positioning grooves are formed on the positioning frame, and fixing holes are correspondingly formed on the positioning blocks.

[0022] The positioning blocks are fixed through the positioning holes and the fixing holes, which is convenient for operation.

[0023] The beneficial effects are as follows:

[0024] 1. The external wall void detection device of the present utility model is configured with a counterweight close to the working surface and a fixed pulley with sliding positioning, so that the detection trolley can always be close to the wall surface, ensuring the accuracy of the detection results. At the same time, the adjustable position of the positioning wheel also provides adaptability for detection under more real conditions.

[0025] 2. Multiple acoustic wave receiving sensors can obtain multiple acoustic wave data, and more accurate detection results can be obtained through the processing of the multiple acoustic wave data.

[0026] 3. The multiple surrounding acoustic wave receiving sensors can collect acoustic waves from different directions, further ensuring the accuracy of the detection results.

[0027] 4. Using universal wheels as the wheels enables the detection trolley to have the function of lateral movement, expanding the detection range from a line to a surface, and having a larger detection range.

[0028] 5. Based on the universal wheels on the detection trolley, the pulley positioning mechanism and the winch are arranged on a movable vehicle, and the movable vehicle can be used for lateral movement, realizing the lateral movement of the detection trolley on the external wall, with a large detection range and further improving the detection efficiency.

[0029] 6. By moving the positioning blocks in the adjustment groove, the position of the fixed pulley is adjusted, which is convenient for operation, and the installation of the positioning frame itself is also more convenient than the installation of the fixed pulley.

[0035] Embodiment:

[0036] An external wall void detection device, as Figure 1 shown, includes a detection trolley 10. Wheels 13 are arranged on one side surface of the detection trolley 10. The side surface of the detection trolley 10 where the wheels 13 are arranged is defined as the working surface. A hammering mechanism 11 and an acoustic wave receiving sensor 12 are arranged on the working surface of the detection trolley 10;

[0037] Counterweights 50 and hook rings 14 are respectively arranged on opposite side surfaces of the detection trolley 10 on the working surface. The counterweights 50 are arranged at positions of the detection trolley 10 close to the working surface;

[0038] It can be understood that in the present application, the hook ring 14 is a general term for the structure at the connection where the sling is connected to the detection trolley 10. It can be ring-shaped or hook-shaped, and its specific structure is not limited herein.

[0039] It further includes a fixed pulley 30 and a winch 40. The steel cable connected to the winch 40 bypasses the fixed pulley 30 and is connected to the hook ring 14. The fixed pulley 30 is arranged on the pulley positioning mechanism 20. As Figure 2 shown, an adjustment groove 22 with a length direction having an angle with the working surface of the detection trolley 10 is provided on the pulley positioning mechanism 20.

[0040] The length direction of the adjustment groove 22 has an angle with the working surface of the detection trolley 10, that is, when the fixed pulley 30 moves along the adjustment groove 22, its lateral distance from the detection trolley 10 changes, and the angle of the sling is changed through this change.

[0041] Since the setting of the winch 40 belongs to the prior art in the hoisting type external wall detection, its specific structure and installation form will not be described in detail in the present application.

[0042] For the external wall void detection device of the present utility model, before operation, according to the position where the pulley positioning mechanism 20 can be installed, the position of the fixed pulley 30 on the pulley positioning mechanism 20 is adjusted along the adjustment groove 22, so that after the sling passing around the fixed pulley 30 is connected to the sling ring, it can present a certain angle, so that the sling has a force towards the wall on the detection trolley 10, and the counterweight 50 always provides a downward pulling force at a position close to the working surface of the detection trolley 10. Therefore, during operation, the detection trolley 10 can always be close to the wall, ensuring the detection quality. At the same time, due to the different situations above the building, in some cases, the installation position of the fixed pulley 30 is not ideal. For example, the position where the fixed pulley 30 can be installed is at a certain distance from the wall. At this time, the traditional fixed-mounted fixed pulley 30 will cause the sling to rub against the corner of the wall. With the assistance of the pulley positioning mechanism 20, the fixed pulley 30 of the present utility model has a certain space for lateral adjustment and can adapt to installations in more situations.

[0043] The external wall void detection device of the present utility model is equipped with a counterweight 50 close to the working surface and a fixed pulley 30 with sliding positioning, enabling the detection trolley 10 to always be close to the wall, ensuring the accuracy of the detection results. At the same time, the adjustable position of the positioning wheel also provides adaptability for detections under more realistic conditions.

[0044] In another embodiment, multiple acoustic wave receiving sensors 12 are provided.

[0045] Multiple acoustic wave receiving sensors 12 can obtain multiple acoustic wave data, and more accurate detection results can be obtained through the processing of the multiple acoustic wave data.

[0046] In another embodiment, multiple acoustic wave receiving sensors 12 are arranged around the hammering mechanism 11.

[0047] The multiple acoustic wave receiving sensors 12 arranged in a surrounding manner can collect acoustic waves from different directions, further ensuring the accuracy of the detection results.

[0048] In another embodiment, the wheels 13 are universal wheels.

[0049] Using universal wheels as the wheels 13 enables the detection trolley 10 to have the function of lateral movement, expanding the detection range from a line to a surface and making the detection range larger.

[0050] In another embodiment, both the pulley positioning mechanism 20 and the winch 40 are arranged on a movable vehicle.

[0051] Based on the universal wheels on the detection trolley 10, by arranging the pulley positioning mechanism 20 and the winch 40 on a movable vehicle, the movable vehicle can be used for lateral movement, realizing the lateral movement of the detection trolley 10 on the external wall. With a large detection range, the detection efficiency is further improved.

[0052] In another embodiment, as Figure 2 shown, the pulley positioning mechanism 20 includes a positioning frame 21. An adjustment groove 22 is formed on the positioning frame 21. Positioning grooves are respectively formed on a pair of opposite side surfaces of the adjustment groove 22 along the length direction of the adjustment groove 22. The two ends of the rotating shaft of the fixed pulley 30 are respectively rotatably connected with positioning blocks 31. The shape of the positioning blocks 31 matches the shape of the positioning grooves.

[0053] By moving the positioning blocks 31 in the adjustment groove 22, the position adjustment of the fixed pulley 30 is realized, which is convenient to operate. The installation of the positioning frame 21 itself is also more convenient than the installation of the fixed pulley 30.

[0054] In another embodiment, as Figure 2 shown, a plurality of positioning holes 23 extending to the positioning grooves are formed on the positioning frame 21, and fixing holes are correspondingly formed on the positioning blocks 31.

[0055] The positioning blocks 31 are fixed through the positioning holes 23 and the fixing holes, which is convenient to operate.
