Description

Technical Field

[0001] The invention relates to the technical field of penetration resistance testing, in particular to a dense mesh penetration resistance testing device. Background Art

[0002] Close-mesh safety nets are generally used in construction projects, and their main function is to provide safety protection at construction sites. They can effectively prevent the free fall of various objects at the construction site, thereby creating a buffering effect, so they are also called "close-mesh building safety vertical nets", which are the colored vertical nets that we usually see surrounding the entire building during construction. Most of them are green, and some are blue or very few other colors. The function of close-mesh safety vertical nets is to reduce casualties or damage caused by objects when construction workers lose their hands (slips) or building materials, tools, etc. fall, so the penetration resistance of close-mesh safety vertical nets is particularly important.

[0003] Current penetration resistance testing equipment usually fixes the dense mesh sample, raises the weight to a certain height, and then lets it fall freely to observe the damage of the sample. Generally, a single penetration resistance test cannot reveal the maximum strength of the sample, and multiple tests are required. During the test, the weight needs to be removed manually and re-clamped at a certain height each time, which affects the efficiency of the test and is quite inconvenient. Summary of the invention

[0006] Furthermore, the first clamping assembly also includes a first bidirectional screw, the first bidirectional screw is rotatably mounted inside the sliding frame via a bearing, and the moving block is threadedly sleeved on the surface of the first bidirectional screw.

[0007] Furthermore, the second clamping assembly also includes a second screw rod, and the second screw rod is rotatably mounted on the bottom of the base through a bearing frame, and a connecting plate is threadedly sleeved on the surface of the second screw rod.

[0008] Furthermore, the top of the second screw rod passes through the base and is fixed with a first bevel gear, one end of the first bidirectional screw rod passes through the slide frame and is installed with a transmission belt, the lower end pulley of the transmission belt is rotatably installed on the base, and the lower end pulley of the transmission belt is fixed with a second bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0009] Furthermore, a base plate is fixed at the bottom of the plug plate, and a second electric push rod is fixed inside the connecting plate. A socket is opened on the side of the base plate facing the second electric push rod, and the extended end of the second electric push rod can be inserted into the socket of the base plate.

[0010] Furthermore, a first gear is fixed to one end of the rotating shaft of the rotating frame, a third gear is fixed at the center of the rotating insert, and the first gear is connected to the second gear through a fixing rod, and the second gear is meshingly connected to the third gear.

[0011] Furthermore, the delivery component also includes a limit plate, two limit plates are symmetrically and slidably installed inside the collection box, and a second bidirectional screw is rotatably installed on the top of the collection box through a bearing seat, and the top of the limit plate is threadedly connected to the second bidirectional screw.

[0012] Furthermore, the collecting box is provided with clamping openings on both sides away from one end of the receiving frame, and the second clamping frame can be inserted into the clamping openings.

[0013] Furthermore, the first bidirectional screw, the second bidirectional screw, the first lead screw and the second lead screw are all controlled by a motor.

[0014] Furthermore, the receiving frame and the installation frame are both conical frames, and an outlet is provided at the bottom of the receiving frame for the detection ball to pass through.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention detects the ball's rolling properties and allows it to fall into the receiving frame and be sent into the collection box through the outlet. Because the collection box is tilted, the detection ball moves to the top under the guidance of the limiting plates on both sides. At this time, the second clamping frame of the second clamping assembly passes through the clamping opening to clamp the detection ball and then transfer it to the position of the first clamping assembly, thereby realizing automatic picking up and resetting of the detection cavity. The motor drives the second bidirectional screw to rotate, and the distance between the two limiting plates can be adjusted to meet the guidance and limitation of the detection ball.

[0017] 2. The present invention drives the rotating disk to rotate through the meshing of the second gear and the third gear, and then the plug plate and the second clamping frame rotate, and the rotation direction of the mounting frame is opposite to that of the rotating disk. When the top of the mounting frame is horizontal, the plug plate and the second clamping frame are located at the position of the delivery component. When the mounting frame rotates toward the receiving frame, the plug plate and the second clamping frame will rotate to a vertical state. While maintaining the connection between the mounting frame and the rotating disk, it is convenient to reset the detection ball by rotating the mounting frame. The mounting frame is driven by the motor provided by the rotating frame.

[0018] 3. The present invention rotates the first bidirectional screw, and the moving block cooperates with the first bidirectional screw thread to slide along the sliding frame, and the two first clamping frames move to clamp the detection ball. When the first clamping frames move away from each other, the detection ball is released, and the detection ball falls freely. Through the transmission connection of the transmission belt, the first bevel gear and the second bevel gear, the first bidirectional screw and the second screw rod are driven synchronously. When the plug plate is in a vertical state, the extended end of the second electric push rod inside the connecting plate is inserted into the plug hole of the bottom plate. At this time, when the second screw rod rotates, it can drive the plug plate to move upward along the rotating plug plate, and the upward moving distance corresponds to the height of the moving plate. At this time, the first clamping frame will also move away synchronously. This structure can meet the requirement that when the second clamping frame leads the detection ball to approach the moving plate, the first clamping frame also just moves to both sides of the detection ball. Because the first clamping frame and the second clamping frame clamp the four points of the sphere respectively, there will be no position of movement interference.

[0019] 4. The present invention can facilitate the second clamping frame to take out the detection ball from the collection box, or transfer the detection ball to the first clamping frame through the telescopic effect of the first electric push rod. When the plug plate needs to be rotated, the extended end of the second electric push rod is separated from the jack of the bottom plate, and thus will not interfere with the rotation of the plug plate. The positions of the base and the second screw rod meet the space required for the rotation of the bottom plate and the plug plate, and keep the position of the second clamping frame always at the tail end of the collection box.

[0020] 5. Compared with the prior art, the present invention, through the cooperation of the first clamping component and the second clamping component, the free-falling detection ball rolls to the outlet position of the collection box of the delivery component through the rotation of the mounting frame, and is clamped by the second clamping component and then moved to the position of the first clamping component to replace the clamping, thereby completing the effect of automatic picking up and automatic clamping of the detection ball, improving the detection efficiency of multiple detections, and replacing manual resetting of the detection ball more conveniently.

When the device is used, the dense mesh sample 1 is placed 2 is installed inside the installation frame 11, and a detection ball 6 of appropriate weight is selected to be clamped in the first clamping assembly 3. The height of the movable plate 22 is adjusted by the first screw rod 21 on the vertical frame, and then the first clamping frame 34 releases the clamping of the detection ball 6, and the detection ball 6 freely falls and impacts the surface of the dense mesh sample 12.

When the plug plate 42 is in a vertical state, the extended end of the second electric push rod 48 inside the connecting plate 47 is inserted into the socket of the bottom plate 49. At this time, when the second screw 46 rotates, it can drive the plug plate 42 to move upward along the rotating plug plate 41, and the upward movement distance corresponds to the height of the moving plate 22. At this time, the first clamping frame 34 will also move away synchronously. This structure can meet the requirement that when the second clamping frame 44 leads the measuring ball 6 to approach the moving plate 22, the first clamping frame 34 also moves to On both sides of the detection ball 6, because the first clamping frame 34 and the second clamping frame 44 clamp the four points of the ball respectively, there will be no position for movement interference. Through the telescopic effect of the first electric push rod 43, the second clamping frame 44 can be convenient for taking out the detection ball 6 from the collection box 52, or transferring the detection ball 6 to the first clamping frame 34. When the plug plate 42 needs to be rotated, the extended end of the second electric push rod 48 is separated from the socket of the bottom plate 49, and thus will not interfere with the rotation of the plug plate 42.

[0033] In this embodiment, a first gear 14 is fixed to one end of the rotating shaft of the rotating frame 13, a third gear 16 is fixed to the center of the rotating plug plate 41, and the first gear 14 is connected to the second gear 15 through a fixing rod, and the second gear 15 is meshed with the third gear 16. When the mounting frame 11 rotates along the rotating frame 13, the first gear 14 is driven to rotate, and the second gear 15 rotates synchronously with the first gear 14. Through the meshing of the second gear 15 and the third gear 16, the rotating plug plate 41 is driven to rotate, and then the plug plate 42 and the second clamping frame 44 rotate, and the mounting frame 11 rotates in opposite directions to the rotating insert disk 41. When the top of the mounting frame 11 is horizontal, the insert plate 42 and the second clamping frame 44 are located at the position of the delivery component 5. When the mounting frame 11 rotates toward the receiving frame 51, the insert plate 42 and the second clamping frame 44 will rotate to a vertical state.

Through the flipping of the installation frame 11 and the rolling of the detection ball 6, it falls into the receiving frame 51 and is sent into the collection box 52 through the outlet. Because the collection box 52 is tilted, the detection ball 6 moves to the top under the limiting guidance of the limiting plates 53 on both sides.
