Abstract
Description
Technical Field
[0001] This utility model relates to the field of emergency rescue equipment testing technology, and in particular to a force measuring device for demolition tools. Background Technology
[0002] In emergency rescue scenarios such as building collapses, traffic accidents, and earthquakes, demolition tools are core equipment for opening lifelines and carrying out rescue operations. Their mechanical properties directly determine rescue efficiency and the survival probability of trapped personnel. However, the current mechanical performance testing system for demolition tools has significant limitations:
[0003] Limited testing scenarios: Existing testing equipment is mostly large, fixed laboratory equipment, which cannot be used for testing in the reserve warehouses, training sites, or front lines of rescue teams. This makes it impossible for rescuers to confirm in real time whether the current performance of the tools meets the standards, and they may bring "hidden failure" tools to the scene, delaying the golden rescue time. It also makes it impossible to reasonably and effectively arrange the use of equipment at the rescue site, affecting the timeliness of the rescue.
[0004] Poor versatility: Traditional detection devices are mostly designed for a single type of demolition tool. One set of equipment is needed to detect expanders, and another set of equipment is needed to detect shears. When changing tools, disassembly and reassembly are required, which is cumbersome and inefficient. Summary of the Invention
[0005] Therefore, a force measuring device for demolition tools is needed to address the technical problem that, during combat readiness and training, it is impossible to confirm whether the mechanical performance of the equipment meets the demolition requirements (such as the supporting force of the jack, the expansion force of the spreader, the squeezing force, the shearing force of the shearer, etc.), and it is also impossible to confirm the mechanical performance of different working points on the working head of the equipment. This leads to the inability to reasonably and effectively arrange the use of equipment at the rescue site, affecting the timeliness of the rescue.

[0082] Please see Figures 1 to 8 As shown, this embodiment relates to a force measuring device for demolition tools, comprising:
[0083] Workbench 1; Workbench 1 is the basic support structure of the entire force measuring device, used to install and fix various functional components and withstand the forces generated during the testing process. Workbench 1 is welded from high-strength alloy steel to ensure that no plastic deformation occurs under the maximum testing force. The high-strength material ensures the structural stability of the equipment under heavy loads, providing a foundation for high-precision testing.
[0084] The first mounting mechanism 2 is fixedly installed on one side of the workbench 1; wherein the first mounting mechanism 2 is a bearing component fixed on the workbench 1, used to install the pressure detection mechanism 4 and the first bearing mechanism 5, and to transmit the detection force to the pressure detection mechanism 4.
[0085] The second mounting mechanism 3 is located on the other side of the workbench 1. The second mounting mechanism 3 is detachably connected to the workbench 1 and is arranged opposite to the first mounting mechanism 2 at a distance. The second mounting mechanism 3 is an adjustable bearing component on the workbench 1, which is arranged opposite to the first mounting mechanism 2 and is used to install the second bearing mechanism 6 and bear the detection reaction force.
[0086] A pressure detection mechanism 4 is housed within the first mounting mechanism 2. This mechanism is a core sensing component that converts the mechanical force output by the demolition tool into an electrical signal, used to quantify and detect the mechanical properties of the tool. When the demolition tool applies force, the force is transmitted to the pressure detection mechanism 4 through the first bearing mechanism 5 and the first mounting mechanism 2. The pressure detection mechanism 4 then converts the force signal into an electrical signal and outputs it to the control mechanism 7. Specifically, in this embodiment, the pressure detection mechanism 4 is a spoke-type tension / compression sensor. This high-precision pressure sensor ensures the accuracy and reliability of the detection data, meeting the performance testing requirements of the demolition tool.
[0087] The first bearing mechanism 5 is connected to the first installation mechanism 2 and is in contact with the pressure detection mechanism 4. The pressure detection mechanism 4 is used to detect the force borne by the first bearing mechanism 5. The first bearing mechanism 5 is a component that is in direct contact with the working head of the demolition tool and is used to transmit and bear the output force of the tool. Its structure is matched with the working head of the demolition tool.
[0088] The second bearing mechanism 6 is connected to the second mounting mechanism 3. The second bearing mechanism 6 and the first bearing mechanism 5 are arranged at intervals and opposite to each other. The second bearing mechanism 6 and the first bearing mechanism 5 cooperate with each other to bear the bearing force of the demolition tool. The second bearing mechanism is a component that directly contacts the working head of the demolition tool and is used to transmit and bear the output force of the tool. Its structure is matched with the working head of the demolition tool.
[0089] The system includes a control mechanism 7, which is electrically connected to the pressure detection mechanism 4. The control mechanism 7 receives and processes the detection signals from the pressure detection mechanism 4 and displays the detection values. Specifically, the control mechanism 7 is an electronic control system used to receive, process, display, and store the output signals from the pressure detection mechanism 4, enabling the visualization and recording of the detection data.
[0090] Specifically, in this embodiment, the force measuring device for the demolition tool selects the appropriate first support mechanism 5 and second support mechanism 6 according to the type of demolition tool to be tested, and installs them onto the first mounting mechanism 2 and the second mounting mechanism 3 respectively. The position of the second mounting mechanism 3 is adjusted according to the specifications of the demolition tool so that the distance between the first support mechanism 5 and the second support mechanism 6 is suitable for the tool's testing requirements. Then, the demolition tool is placed between the first support mechanism 5 and the second support mechanism 6, the power to the control mechanism 7 is turned on, and the demolition tool is operated so that its working head contacts the support mechanism and applies force. The force is transmitted to the pressure detection mechanism 4 through the first support mechanism 5 and the first mounting mechanism 2. The pressure detection mechanism 4 converts the force signal into an electrical signal and transmits it to the control mechanism 7. The control mechanism 7 processes the signal and displays the force value in real time on the display screen 703. After the test is completed, the demolition tool is removed, and the test is finished. The entire operation process is simple and convenient, and highly versatile: with the replaceable first bearing mechanism 5, second bearing mechanism 6 and adjustable second mounting mechanism 3, it can be adapted to various types of demolition tools such as expanders and shears; accurate detection: adopting a high-precision pressure detection mechanism 4, combined with a dedicated first bearing structure and first mounting mechanism 2, ensures that the detection data truly reflects the actual performance of the tool; the control mechanism 7 enables real-time display of data, improving detection efficiency.

The upper and lower ends of the two side plates 103 are respectively welded to the upper base 101 and the lower base 102 by screw fixing, forming a rectangular frame structure. The frame structure design reduces the weight of the equipment while ensuring overall rigidity, facilitating movement and installation. Both the upper base 101 and the lower base 102 are provided with multiple through holes 104, which are evenly distributed at intervals. The distribution range of the multiple through holes 104 covers 80% of the length of the workbench 1, providing sufficient adjustment space for the second mounting mechanism 3. In this embodiment, there are two rows of multiple through holes 104 to improve the stability of the connection between the movable plate 301 and the upper base 101 and the lower base 102.
