Description

Technical Field

[0001] This application relates to the technical field of building material performance testing, and in particular to an impact simulation device. Background Technology

[0002] Cement performance testing is a crucial step in ensuring building quality and safety, with impact resistance testing being particularly critical. To assess cement's impact resistance, a heavy object is dropped into the cement. This process requires not only lifting the object to a certain height but also ensuring accurate impact on the cement sample and controlling the impact point. Current technologies use cranes to lift the object, but this process can cause swaying, making it difficult to control the landing point. Utility Model Content

[0003] To stabilize the lifting of heavy objects, this application provides an impact simulation device.

[0004] The impact simulation device provided in this application adopts the following technical solution:

[0005] An impact simulation device includes a lifting device, which comprises a lifting mechanism, a lifting and translating mechanism, a lifting platform, a first rotating shaft, and a second rotating shaft. The first rotating shaft and the second rotating shaft are both arranged along a first direction and are rotatably connected to the lifting platform around their own axes. The lifting mechanism is used to drive the first rotating shaft to reciprocate along a vertical direction, and the lifting and translating mechanism is used to drive the second rotating shaft to reciprocate along a vertical direction and a second direction perpendicular to the first direction.

[0006] By adopting the above technical solution, by controlling the first rotating shaft and the second rotating shaft to move simultaneously in the vertical direction, the lifting plate can be controlled to rise or fall. By controlling the second rotating shaft to move closer to or further away from the first rotating shaft while rising or falling, the angle between the lifting plate and the horizontal direction can be controlled.

[0007] Optionally, the lifting mechanism includes two first lifting components. Each first lifting component includes a first vertical rail, a first vertical motor, a first vertical screw, and a first vertical nut. The first vertical nut is slidably connected to the first vertical rail. The first vertical screw is rotatably connected to the first vertical rail around its own axis and meshes with the first vertical nut. The first vertical motor is located at the top of the first vertical rail and is driven by the first vertical screw. The first vertical nut is fixedly connected to both ends of the first rotating shaft.

[0008] By adopting the above technical solution, the first vertical motor drives the first vertical screw to rotate, and the rotation of the first vertical screw drives the first vertical nut meshing with it to move along the length direction of the first vertical track, thereby driving the first rotating shaft to move in the vertical direction.

[0009] Optionally, the lifting and translating mechanism includes two second lifting components and two second moving components. Each second lifting component includes a second vertical rail, a second vertical motor, a second vertical screw, and a second vertical nut. The second vertical nut is slidably connected to the second vertical rail. The second vertical screw is rotatably connected to the second vertical rail around its own axis and meshes with the second vertical nut. The second vertical motor is located at the top of the second vertical rail and is driven by the second vertical screw. The second vertical nut is fixedly connected to both ends of the second rotating shaft. Each second moving component includes a second horizontal motor, a second horizontal screw, a second horizontal nut, and a second horizontal rail arranged along the second direction. One end of the second horizontal rail is fixedly connected to the bottom end of the first vertical rail. The second horizontal nut is slidably connected to the second horizontal rail. The second horizontal screw is rotatably connected to the second horizontal rail around its own axis and meshes with the second horizontal nut. The second horizontal motor is located at the end of the second horizontal rail away from the first vertical rail and is driven by the second horizontal screw. The second horizontal nut is fixedly connected to the bottom end of the second vertical rail.

[0010] By adopting the above technical solution, the second vertical motor drives the second vertical screw to rotate, and the rotation of the second vertical screw causes the second vertical nut meshing with it to move along the length direction of the second vertical track, thereby driving the second rotating shaft to move in the vertical direction; at the same time, the second horizontal motor drives the second horizontal screw to rotate, and the rotation of the second horizontal screw causes the second horizontal nut meshing with it to move along the length direction of the second horizontal track, thereby driving the second vertical track to move in the second direction, thus realizing the adjustment of the lifting plate position and improving the flexibility and practicality of the equipment.

[0011] Optionally, the second moving component further includes a baffle, which is arranged vertically, and the two ends of the bottom of the baffle are respectively fixedly connected to the second transverse nut.

[0012] By adopting the above technical solution, the baffle can play a blocking role, preventing the heavy objects on the lifting platform from falling from the side near the lifting and translation mechanism.

[0013] Optionally, a protective net may also be included, which is located on the side of the lifting mechanism away from the lifting and translating mechanism.

[0014] By adopting the above technical solution, the protective net can shield the testing area, preventing debris generated by impact from splashing out during the testing process and ensuring the safety of the operators.

[0015] Optionally, a crane is provided on the side of the top of the first vertical track away from the second vertical track.

[0016] By adopting the above technical solutions, the crane can assist in lifting heavy objects onto the lifting platform, reducing the labor intensity of operators and improving testing efficiency.

[0017] Optionally, a translation mechanism is also included, comprising a first moving component. The first moving component includes a first transverse motor, a first transverse lead screw, a first transverse front lead screw, a first transverse rear lead screw, and a first transverse track arranged along the first direction. The first transverse front lead screw and the first transverse rear lead screw are slidably connected to the first transverse track. The first transverse lead screw is rotatably connected to the first transverse track around its own axis and simultaneously meshes with the first transverse front lead screw and the first transverse rear lead screw. The first transverse motor is located at one end of the first transverse track and is drivenly connected to the first transverse lead screw. The first transverse front lead screw is fixedly connected to one of the two second transverse tracks, and the first transverse rear lead screw is fixedly connected to the other of the two second transverse tracks.

[0018] By adopting the above technical solution, the first transverse motor can drive the first transverse screw to rotate. The rotation of the first transverse screw drives the first transverse front screw nut and the first transverse rear screw nut meshing with it to move simultaneously along the length direction of the first transverse track. This, in turn, drives the two second transverse tracks to move along the length direction of the first transverse track, that is, to move along the first direction, thereby realizing the lateral position adjustment of the lifting device. This allows the lifting device to be moved to different detection positions, improving the flexibility of the equipment.

[0019] Optionally, the number of the first moving components is at least two.

[0020] By adopting the above technical solution and setting at least two first moving components, the translation mechanism can more stably support the entire lifting device, ensuring the stability of the lifting device during use.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application uses a lifting mechanism to drive the first rotating shaft to reciprocate in the vertical direction, and a lifting and translation mechanism to drive the second rotating shaft to reciprocate in the vertical direction and in a second direction perpendicular to the first direction, thereby realizing the lifting and lowering of the lifting plate and the change of its angle, so as to realize the stable lifting or throwing of heavy objects, and improve the flexibility and practicality of the testing equipment.

[0023] 2. Cranes can assist in lifting heavy objects onto the lifting platform, reducing the labor intensity of operators and improving testing efficiency;

[0024] 3. The first moving component enables the lifting device to move along the length of the first transverse track, thereby allowing the lifting device to be moved to different detection positions, improving the flexibility of the equipment and facilitating multi-point detection.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0028] In this application, unless otherwise stated, directional terms such as "inner" and "outer" refer to the outline of the corresponding component itself, and directional terms such as "first direction" refer to... Figure 1 The middle x-direction points to the direction, and the second direction refers to... Figure 1 The y-axis points in the direction.

[0029] This application discloses an impact simulation device.

[0030] like Figure 1 As shown, the impact simulation equipment includes a lifting device. The lifting device includes a lifting mechanism 1, a lifting and translating mechanism 2, a lifting platform, a first rotating shaft, and a second rotating shaft. Both the first and second rotating shafts are arranged along a first direction. The first and second rotating shafts are rotatably connected to the lifting platform around their own axes. The lifting mechanism 1 is used to drive the first rotating shaft to reciprocate along the vertical direction, and the lifting and translating mechanism 2 is used to drive the second rotating shaft to reciprocate along the vertical direction and a second direction perpendicular to the first direction.

[0031] By controlling the first and second rotating shafts to move simultaneously in the vertical direction, the lifting platform can be controlled to rise or fall. By controlling the second rotating shaft to move closer to or further away from the first rotating shaft while rising or falling, the angle between the lifting platform and the horizontal direction can be controlled.

[0032] like Figure 1 As shown, specifically, the lifting mechanism 1 includes two first lifting components. Each first lifting component includes a first vertical rail 101, a first vertical motor 102, a first vertical lead screw 103, and a first vertical nut 104. The first vertical nut 104 is slidably connected to the first vertical rail 101. The first vertical lead screw 103 is rotatably connected to the first vertical rail 101 around its own axis and meshes with the first vertical nut 104. The first vertical motor 102 is located at the top of the first vertical rail 101 and is driven by the first vertical lead screw 103. The first vertical nut 104 is fixedly connected to both ends of the first rotating shaft. By simultaneously driving the first vertical lead screw 103 to rotate using the two first vertical motors 102, the rotation of the first vertical lead screw 103 causes the meshing first vertical nut 104 to move along the length of the first vertical rail 101, thereby driving the first rotating shaft to move vertically.

[0033] like Figure 1 As shown, specifically, the lifting and translating mechanism 2 includes two second lifting components and two second moving components. The second lifting components include a second vertical rail 201, a second vertical motor 202, a second vertical lead screw 203, and a second vertical nut 204. The second vertical nut 204 is slidably connected to the second vertical rail 201. The second vertical lead screw 203 is rotatably connected to the second vertical rail 201 around its own axis and meshes with the second vertical nut 204. The second vertical motor 202 is located at the top of the second vertical rail 201 and is driven by the second vertical lead screw 203. The second vertical nut 204 is fixedly connected to both ends of a second rotating shaft. The second moving components include a second... The system includes a horizontal motor 205, a second horizontal lead screw 206, a second horizontal lead screw nut 207, and a second horizontal rail 208 arranged along a second direction. One end of the second horizontal rail 208 is fixedly connected to the bottom end of the first vertical rail 101. The second horizontal lead screw nut 207 is slidably connected to the second horizontal rail 208. The second horizontal lead screw 206 is rotatably connected to the second horizontal rail 208 around its own axis and meshes with the second horizontal lead screw nut 207. The second horizontal motor 205 is located at the end of the second horizontal rail 208 away from the first vertical rail 101 and is driven by the second horizontal lead screw 206. The second horizontal lead screw nut 207 is fixedly connected to the bottom end of the second vertical rail 201.

[0034] The second vertical motor 202 drives the second vertical screw 203 to rotate. The rotation of the second vertical screw 203 causes the second vertical nut 204, which meshes with it, to move along the length of the second vertical track 201. This, in turn, causes the second rotating shaft to move in the vertical direction. While the lifting and translation mechanism 2 drives the second rotating shaft to move in the vertical direction, the lifting mechanism 1 drives the first rotating shaft to move in the vertical direction. When the two move at the same speed, the height of the lifting plate in the vertical direction can be adjusted.

[0035] Alternatively, the second transverse motor 205 can be used to drive the second transverse lead screw 206 to rotate. The rotation of the second transverse lead screw 206 drives the second transverse nut 207, which meshes with it, to move along the length direction of the second transverse track 208. This, in turn, drives the second vertical track 201 to move along the second direction. While the lifting and translating mechanism 2 drives the second rotating shaft to move along the second direction, the lifting mechanism 1 drives the first rotating shaft to move along the vertical direction, and the lifting and translating mechanism 2 drives the second rotating shaft to move along the vertical direction. When the first rotating shaft and the second rotating shaft move along the vertical direction at different speeds, and the second rotating shaft moves along the second direction at the same time, the angle between the lifting plate and the horizontal direction can be adjusted.

[0036] like Figure 1 As shown, the second moving component also includes a baffle 4, which is arranged vertically, and its two ends are fixedly connected to the second transverse nut 207. The baffle 4 can act as a barrier to prevent heavy objects on the lifting platform from falling from the side near the lifting and translating mechanism 2.

[0037] Since the baffle 4 restricts the direction of the falling weight, a protective net 5 can be installed on the side of the lifting mechanism 1 away from the lifting and translation mechanism 2. The protective net 5 can shield the detection area and prevent debris from splashing out during the detection process, especially when the weight impacts the cement to be tested, thus ensuring the safety of the experimental personnel.

[0038] like Figure 1 As shown, to facilitate the loading of heavy objects onto the lifting platform, a crane 6 is provided on the top side of the first vertical track 101 away from the second vertical track 201. The crane 6 can assist in lifting heavy objects onto the lifting platform, reducing the labor intensity of operators and improving inspection efficiency.

[0039] like Figure 1As shown, the impact simulation device may further include a translation mechanism 3. The translation mechanism 3 includes a first moving component, which includes a first transverse motor 301, a first transverse lead screw 302, a first transverse front lead screw 303, a first transverse rear lead screw 304, and a first transverse track 305 arranged along a first direction. The first transverse front lead screw 303 and the first transverse rear lead screw 304 are slidably connected to the first transverse track 305. The first transverse lead screw 302 is rotatably connected to the first transverse track 305 around its own axis and simultaneously meshes with the first transverse front lead screw 303 and the first transverse rear lead screw 304. The first transverse motor 301 is located at one end of the first transverse track 305 and is drivenly connected to the first transverse lead screw 302. The first transverse front lead screw 303 is fixedly connected to one of the two second transverse tracks 208, and the first transverse rear lead screw 304 is fixedly connected to the other of the two second transverse tracks 208.

[0040] The first transverse motor 301 drives the first transverse screw 302 to rotate. The rotation of the first transverse screw 302 causes the first transverse front screw 303 and the first transverse rear screw 304, which mesh with it, to move simultaneously along the length direction of the first transverse track 305. This, in turn, can drive the two second transverse tracks 208 to move along the length direction of the first transverse track 305, that is, to move along the first direction. This realizes the adjustment of the transverse position of the lifting device, so that the lifting device can be moved to different detection positions, improving the flexibility of the equipment.

[0041] To ensure the stability of the lifting device during use, the number of first moving components is at least two. Setting at least two first moving components allows the translation mechanism 3 to support the entire lifting device more stably.

[0042] The implementation principle of the impact simulation device in this application embodiment is as follows: The cement sample to be tested is laid on the protective net 5. The lifting mechanism 1 and the lifting and translation mechanism 2 are controlled to keep the lifting platform horizontal and at its lowest position. A crane 6 is used to assist in transporting the heavy object to the lifting platform. The lifting mechanism 1 and the lifting and translation mechanism 2 are controlled to tilt the lifting platform towards the baffle 4, and the height of the lifting platform is gradually increased. The translation mechanism 3 is used to adjust the lateral position of the lifting device, moving the lifting device to the testing position. The lifting mechanism 1 and the lifting and translation mechanism 2 are controlled to tilt the lifting platform away from the baffle 4, causing the heavy object to slide off the baffle 4 under gravity and collide with the cement sample to be tested. Finally, the experimental data is recorded.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
