Technical Field

[0001] This utility model relates to the field of gas detector detection technology, and in particular to a detector collision device. Background Technology

[0002] A gas detector is an instrument for detecting gas concentrations. It is suitable for hazardous locations where flammable or toxic gases are present, and can continuously monitor the concentration of the gas in the air up to its lower explosive limit. It is widely used in various industries such as gas, petrochemicals, metallurgy, steel, coking, and power generation, where flammable or toxic gases are present, making it an ideal monitoring instrument for ensuring property and personal safety.

[0003] Gas detector testing aims to ensure product quality, performance, safety, and compliance, thereby meeting consumer needs, protecting consumer rights, and maintaining corporate reputation and market competitiveness. Product testing verifies whether products meet preset quality standards and technical requirements. Among these, collision testing is a standard requirement. In previous tests, different manufacturers used different methods to fix products, making the operation of related equipment inconvenient. Different fixtures had to be developed for different fixing methods, wasting time and increasing costs. Therefore, we propose a detector collision device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies. In previous tests, different manufacturers used different methods to fix products, making the operation of related equipment inconvenient. Different fixtures had to be developed for different fixing methods, which wasted time and increased costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detector collision device includes a collision test chamber and a pendulum mechanism, wherein the pendulum mechanism is installed inside the collision test chamber;

[0007] The pendulum mechanism includes a support structure, a steel hub, a pendulum rod, a hammer head, a steel shaft, a support frame, and a pulley. The pendulum rod is welded to the steel hub, and the hammer head is welded to the other end of the pendulum rod. The steel shaft is built into the steel hub and connected to the support frame at both ends. There are two support frames installed on the support structure, and the pulley is installed at one end of the steel hub.

[0008] Furthermore, the hammerhead is a hexahedron with a sloping surface, which is the collision surface.

[0009] Furthermore, the support structure includes a base plate, a movable plate, and a support column. The base plate and the movable plate correspond to each other, and the base plate is installed on the bottom surface inside the collision test chamber and connected by a support column that passes through the corner of the base plate and the movable plate.

[0010] Furthermore, locking blocks are installed at the top of the movable plate via the support columns to fix the height of the movable plate.

[0011] Furthermore, two counterweight arms are mounted on the steel hub in the direction opposite to the swing arm, and an adjustable counterweight block is installed on the two counterweight arms to balance the hammer head with the counterweight arms.

[0012] Furthermore, a cable is wound around the pulley, with one end of the cable fixed to the pulley and the other end attached to a working weight.

[0013] Furthermore, the bottom of the movable plate is used to install a gas detector. By adjusting the movable plate up and down, the center of the impact surface of the hammer head collides with the gas detector from a horizontal direction.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By designing a unified pendulum mechanism and adjustment mechanism, it can adapt to the differences in product fixing methods of different manufacturers, eliminating the need to design separate fixtures for each fixing method, which greatly improves the versatility and flexibility of testing.

[0016] 2. The design of the pendulum mechanism makes operation simpler. By adjusting the height of the movable plate and the position of the counterweight, collision tests on gas detectors of different sizes and weights can be easily achieved, reducing the complexity of operation.

[0017] 3. Since there is no need to make multiple fixtures for different fixing methods, the testing cost is significantly reduced, while the testing efficiency is improved and the time wasted due to changing fixtures is reduced.

[0018] 4. By precisely adjusting the positions of the movable plate and the counterweight, it can be ensured that the center of the hammer's impact surface accurately collides with the gas detector from the horizontal direction, thus improving the accuracy and reliability of the test.

[0019] 5. The design of the support structure and pendulum mechanism ensures the stability of the equipment, maintaining structural integrity and safety even under high-speed collisions, thus ensuring the safety of the testing process. Attached Figure Description

[0029] Example 1

[0030] like Figure 1 As shown, this utility model provides a technical solution: the detector collision device of this embodiment includes a collision test box 1 and a pendulum mechanism 2, the pendulum mechanism 2 being installed inside the collision test box 1;

[0031] The pendulum mechanism 2 includes a support structure 21, a steel hub 22, a pendulum rod 23, a hammer head 24, a steel shaft 25, a support frame 26, and a pulley 27. The pendulum rod 23 is welded to the steel hub 22, and the hammer head 24 is welded to the other end of the pendulum rod 23. The steel shaft 25 is built into the steel hub 22 and is connected to the support frame 26 at both ends. There are two support frames 26 installed on the support structure 21. The pulley 27 is installed at one end of the steel hub 22 and is used to connect to the working weight 272. Gravitational potential energy is transmitted through the cable 271, enabling the pendulum mechanism 2 to swing.

[0032] It should be added that two counterweight arms 28 are mounted on the steel wheel hub 22 in the direction opposite to the pendulum rod 23. An adjustable counterweight block 29 is installed on the two counterweight arms 28 to balance the pendulum mechanism 2 and ensure that the hammer head 24 can remain stable during the swing. By adjusting the position of the counterweight block 29, the balance state of the pendulum mechanism 2 can be precisely controlled.

[0033] A cable 271 is wound around the pulley 27. One end of the cable 271 is fixed to the pulley 27, and the other end is attached to the working weight 272. The cable 271 is connected to the pulley 27 to provide gravitational potential energy to the pendulum mechanism 2, enabling it to swing and collide with the gas detector. The mass of the working weight 272 can be adjusted as needed to meet the requirements of different test conditions.

[0034] Example 2

[0035] like Figure 1 As shown, the hammer head 24 is a hexahedron with an inclined surface, which is the collision surface. The hammer head 24 is made of hard aluminum alloy AlCu4SiMg (treated by solution treatment and aging), which has high hardness and wear resistance, and can meet the requirements of collision testing.

[0036] The support structure 21 includes a base plate 211, a movable plate 212, and a support column 213. The base plate 211 and the movable plate 212 correspond to each other. The base plate 211 is installed on the bottom surface inside the collision test chamber 1 and is connected by the support column 213 that passes through the corner of the base plate 211 and the movable plate 212.

[0037] Locking blocks 214 are installed at the top of the movable plate 212 via support columns 213. The height of the movable plate 212 is fixed by the locking blocks 214 to accommodate gas detectors of different sizes and weights.

[0038] Meanwhile, the bottom of the movable plate 212 is used to install a gas detector. By adjusting the movable plate 212 up and down, the center of the collision surface of the hammer 24 collides with the gas detector from the horizontal direction.

[0039] The working process of this utility model is as follows: First, adjust the movable plate 212 and the gas detector. According to the size and weight of the gas detector to be tested, adjust the height of the movable plate 212. Fix the movable plate 212 to the appropriate position on the support column 213 by locking block 214. Install the gas detector at the bottom of the movable plate 212, ensuring that its center of impact surface with the hammer head 24 is aligned in the horizontal direction. Next, balance the pendulum mechanism 2, remove the working weight 272, and ensure that the pendulum mechanism 2 is in a free state. Adjust the position of the counterweight block 29 on the two counterweight arms 28, pull the pendulum rod 23 to connect with the working weight 272, pull the pendulum rod 23 to a horizontal position, and ensure that the hammer head 24 is in the pre-release preparation state. Re-tie the working weight 272 to the other end of the cable 271 to ensure a firm connection. Under the premise of ensuring personnel safety, release the pendulum mechanism 2. The working weight 272 will drive the pendulum mechanism 2 to rotate, and the hammer head 24 will strike the gas detector at a certain speed and angle to complete the collision test.

[0040] The working weight 272 will cause the hammer head 24 to rotate by 3π / 2 rad in the collision gas detector;

[0041] The mass of the working weight 272 is: 0.388 / 3πr kg;

[0042] In the formula: R--effective radius m of pulley 27. When r is 0.075m, the mass of working hammer 272 is about 0.55kg and the mass of hammer head 24 is about 0.79kg.

[0043] Finally, observe and record the state of the gas detector after the collision, including whether it is damaged or whether its functions are disabled. Evaluate the impact resistance and safety of the gas detector based on the test results, and complete the collision test of the gas detector.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
