Description

Technical Field

[0001] This utility model relates to the field of building curtain wall testing technology, and in particular to a test device for the impact resistance performance of building curtain walls. Background Technology

[0002] The building curtain wall impact resistance test device is an experimental device specifically designed to evaluate the resistance of curtain wall systems (such as glass, metal panels, stone, etc.) to damage when subjected to impact. Its purpose is to simulate impacts that may be encountered in actual use (such as flying stones, hail, man-made impacts, etc.) to ensure that the curtain wall meets the safety requirements of relevant standards.

[0003] Existing building curtain wall impact resistance testing equipment has obvious defects in use, namely, the lack of a structure for cleaning up debris generated during the impact. When the equipment conducts impact tests on curtain wall samples, flying glass shards, metal fragments and other waste materials will be directly scattered on the floor of the work area, which not only affects the cleanliness of the testing environment, but may also pose a safety hazard to the operators. In addition, the accumulated debris will increase the workload of subsequent cleaning and reduce the testing efficiency.

[0004] Therefore, in view of the problem that the existing building curtain wall impact resistance testing device does not have a debris cleaning structure during use, and the debris generated during the impact falls directly onto the work area floor, affecting the working environment, a new building curtain wall impact resistance testing device can be designed. Utility Model Content

[0005] To overcome the problem that existing building curtain wall impact resistance testing devices do not have a debris cleaning structure during use, causing debris generated during impact to fall directly onto the work area floor and affect the working environment.

[0006] The technical solution of this utility model is as follows: a building curtain wall impact resistance testing device, including a base; it also includes an inclined groove opened on the top of the base, a collecting mechanism is provided at the right end of the base, an installation groove is opened on the front side of the top of the base, a drive motor is installed at the right end of the installation groove, a lead screw is connected to the output end of the drive motor, the drive motor is used to drive the lead screw to rotate, the left end of the lead screw is rotatably connected to the left side of the installation groove, a movable seat is threaded through the outer side of the lead screw, a connecting rod is provided at the top of the movable seat, bristles are provided at the bottom of the connecting rod, a limit component is provided on the rear side of the top of the base, an installation component is provided on the outer side of the base, a positioning component is connected to the inner side of the installation component, a gantry beam is provided on the left side of the top of the base, a suspension rope is connected to the bottom of the gantry beam, and an impact ball is connected to the bottom end of the suspension rope.

[0007] Preferably, by setting a drive motor, its output end can drive the lead screw to rotate during operation. When the lead screw rotates, it drives the moving seat that is threaded with it to move left and right, so that the connecting rod drives the bristles to clean the inclined groove. This allows all the debris on the surface of the inclined groove to slide into the collection mechanism, thus cleaning up the debris. This solves the problem that the existing building curtain wall impact resistance testing device does not have a debris cleaning structure during use, and the debris generated during the impact falls directly onto the floor of the work room, affecting the working environment.

[0008] Preferably, the collection mechanism includes a slag collection component and a blocking component. The slag collection component is used to collect the slag that slides down from the inclined chute, and the blocking component is used to prevent the slag from splashing.

[0009] Preferably, the slag collection assembly includes a collection box, hooks, and support plates; the collection box is provided at the right end of the base, and hooks are installed at both the front and rear ends of the collection box; support plates are installed on both the front and rear sides of the right end of the base, and the hooks are connected to the support plates.

[0010] Preferably, the blocking assembly includes a baffle, connecting pieces, and connecting screws. The baffle is provided on the top of the collection box, and multiple connecting pieces are provided on the right side of the baffle. Two connecting screws are connected to the connecting pieces, and the baffle and the collection box are fixed together by the connecting pieces and connecting screws.

[0011] Preferably, the limiting assembly includes a limiting groove, a limiting rod, and a limiting block; the limiting groove is provided on the top rear side of the base, the limiting rod is provided inside the limiting groove, the limiting rod is slidably connected to the limiting block through its outer side, and the top of the limiting block is fixedly connected to the connecting rod.

[0012] Preferably, the mounting components include support rods and a positioning frame; support rods are provided on both the front and rear sides of the base, and a positioning frame is provided between the two support rods.

[0013] Preferably, the positioning component includes a sliding groove, a clamping plate, a clamping groove, positioning holes, and positioning bolts; the upper and lower sides of the positioning frame are provided with sliding grooves, and two clamping plates are slidably connected inside the positioning frame through the sliding grooves. The opposite surfaces of the two clamping plates are provided with clamping grooves. The top of the positioning frame is provided with multiple positioning holes distributed at equal intervals, and the top of the clamping plates is provided with positioning bolts.

[0014] The beneficial effects of this utility model are:

[0015] The synergistic effect of the inclined groove and movable bristles significantly improves the efficiency of debris removal. After the debris generated during the experiment naturally slides onto the surface of the inclined groove, the reciprocating motion of the bristles can quickly sweep the debris into the collection mechanism, effectively avoiding secondary pollution caused by debris accumulation. This automatic cleaning mechanism not only saves cleaning time but also ensures the cleanliness of the experimental environment and improves operational safety. At the same time, the continuous debris collection function can prevent debris from scattering, maintain the long-term stable operation of the equipment, extend the service life of the instrument, and realize the simultaneous conduct of testing and cleaning, greatly improving work efficiency.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a building curtain wall impact resistance testing device, including a base 1; it also includes an inclined groove 2 formed on the top of the base 1, a collecting mechanism provided at the right end of the base 1, an installation groove 4 formed on the front top of the base 1, a drive motor 5 installed at the right end of the installation groove 4, a lead screw 6 connected to the output end of the drive motor 5, the drive motor 5 driving the lead screw 6 to rotate, the left end of the lead screw 6 being rotatably connected to the left side of the installation groove 4, a movable seat 7 threadedly connected to the outer side of the lead screw 6, a connecting rod 8 provided on the top of the movable seat 7, bristles 9 provided at the bottom of the connecting rod 8, and a limit assembly provided on the rear top of the base 1. An installation component is provided on the outer side of the base 1, and a positioning component is connected to the inner side of the installation component. A gantry beam 13 is provided on the top left side of the base 1, and a suspension rope 14 is connected to the bottom of the gantry beam 13. An impact ball 15 is connected to the bottom end of the suspension rope 14. The torque output by the drive motor 5 drives the lead screw 6 to rotate. The rotational motion is converted into linear motion by the threaded pair transmission between the lead screw 6 and the moving seat 7, so that the moving seat 7 moves back and forth along the axial direction. The moving seat 7 drives the cleaning brush assembly to move through the rigid connecting rod 8. The brush bristles 9 sweep the surface of the inclined groove 2 in a directional manner, forcing the attached debris to detach from the groove surface and slide into the debris collection device under the action of gravity, thereby completing the cleaning operation of the inclined groove 2.

[0024] Please see Figure 2 and Figure 4 In this embodiment, the collection mechanism includes a slag collection component and a blocking component. The slag collection component is used to collect the slag that slides down from the inclined chute 2, and the blocking component is used to block the slag from splashing. The slag collection component includes a collection box 31, hooks 32, and support plates 33. The collection box 31 is provided at the right end of the base 1. Hooks 32 are installed at both the front and rear ends of the collection box 31. Support plates 33 are installed on both the front and rear sides of the right end of the base 1. The hooks 32 are hooked to the support plates 33. By setting the hooks 32 and the support plates 33, the collection box 31 can be easily disassembled and assembled, thereby facilitating the dumping of slag. The blocking component includes a baffle 34, connecting pieces 35, and connecting screws 36. The baffle 34 is provided at the top of the collection box 31. Multiple connecting pieces 35 are provided on the right side of the baffle 34. Two connecting screws 36 are connected to the connecting pieces 35. The baffle 34 and the collection box 31 are fixed together by the connecting pieces 35 and the connecting screws 36. By setting the baffle 34, the slag from splashing can be blocked, ensuring that the slag can fall into the collection box 31.

[0025] Please see Figures 1-5In this embodiment, the limiting component includes a limiting groove 101, a limiting rod 102, and a limiting block 103. A limiting groove 101 is formed on the rear top side of the base 1. A limiting rod 102 is disposed inside the limiting groove 101. A limiting block 103 is slidably connected to the outer side of the limiting rod 102. The top of the limiting block 103 is fixedly connected to the connecting rod 8. By setting the limiting block 103 and the limiting rod 102, when the connecting rod 8 moves, it drives the limiting block 103 to slide synchronously on the outer side of the limiting rod 102. The limiting rod 102 can restrict the sliding direction of the limiting block 103, thereby improving the stability of the moving connecting rod 8. The mounting component includes a support rod 111 and a positioning frame 112. Support rods 111 are provided on both the front and rear sides of the base 1, and a positioning frame 112 is provided between the two support rods 111. By setting the support rods 111... 1. The positioning frame 112 can be installed. The positioning components include a sliding groove 121, a clamping plate 122, a clamping groove 123, a positioning hole 124, and a positioning bolt 125. Sliding grooves 121 are provided on both the upper and lower sides of the positioning frame 112. Two clamping plates 122 are slidably connected inside the positioning frame 112 through the sliding grooves 121. The opposite surfaces of the two clamping plates 122 are provided with clamping grooves 123. Multiple positioning holes 124 are provided at equal intervals on the top of the positioning frame 112. Positioning bolts 125 are provided on the top of the clamping plates 122. By setting the clamping plates 122, the clamping plates 122 can slide inside the sliding grooves 121, thereby clamping and positioning building curtain walls of different sizes through the clamping grooves 123. The clamping plates 122 can be positioned by the cooperation of the positioning holes 124 and the positioning bolts 125 to prevent them from loosening.

[0026] During operation, the building curtain wall sample is first placed on the left side of the base 1. The sample slides within the groove 121 via two clamping plates 122 on the positioning frame 112, and is clamped by the clamping groove 123. Positioning bolts 125 are used to lock the clamping plates 122 in place through the positioning holes 124 to prevent loosening. Then, the impact ball 15, suspended at the bottom of the rope 14 of the gantry beam 13, is released to fall freely and impact the surface of the curtain wall sample. The resulting debris falls into the inclined groove 2 at the top of the base 1. The drive motor 5 starts, and its output drives the lead screw 6 to rotate, causing the movable seat 7, threadedly connected to the lead screw 6, to move left and right within the mounting groove 4. The movable seat 7, via the connecting rod 8, drives the brush bristles 9 at its bottom. The brush moves along the surface of the inclined groove 2 for cleaning. At the same time, the connecting rod 8 drives the limiting block 103 fixed on it to slide outside the limiting rod 102 in the limiting groove 101 to ensure stable movement. The debris swept by the brush 9 slides down the inclined surface of the inclined groove 2 to the right end of the base 1. The collection box 31 set at the right end of the base 1 is hung on the support plates 33 on the front and rear sides of the right end of the base 1 by the hooks 32 at its front and rear ends to catch the falling debris. The baffle 34 set at the top of the collection box 31 is fixed by the connecting piece 35 and the connecting screw 36 to prevent debris from splashing and ensure that the debris falls into the collection box 31. After the test is completed, the hooks 32 can be removed to remove the collection box 31 for dumping the debris.

[0027] Through the above steps, by setting up the drive motor 5, the output shaft drives the lead screw 6 to rotate during operation. Since the moving seat 7 and the lead screw 6 form a threaded engagement, when the lead screw 6 rotates, it forces the moving seat 7 to make linear reciprocating motion along the guide rail, thereby converting the linear motion of the moving seat 7 into the cleaning action of the brush bristles 9. The brush bristles 9 contact the surface of the inclined groove 2, and completely peel off the debris in the groove during the reciprocating motion. The removed debris slides down the inclined groove 2 and finally falls into the collection mechanism. This solves the problem that the existing building curtain wall impact resistance testing device does not have a debris cleaning structure during use, and the debris generated during the impact falls directly onto the floor of the work room, affecting the working environment.
