Detailed implementation manners
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0027] As Figures 1 to 7 shown, a physical property detection device for a building curtain wall provided by the present utility model includes a workbench 1. Motors 2 are respectively arranged on the right sides of the front and rear sides of the workbench 1. The output ends of the motors 2 are fixedly connected with a positive and negative screw rod 3. The left side of the positive and negative screw rod 3 is movably connected to the left side of the inner wall of the workbench 1. A fixed frame 4 is fixedly connected to the top of the workbench 1. Two electric cylinders 5 are fixedly installed on the top of the fixed frame 4. The electric cylinders 5 are vertically downward. The output ends of the electric cylinders 5 are fixedly connected with a connecting plate 6. The middle part of the lower surface of the connecting plate 6 is fixedly connected with an impact head 7. The impact head 7 is vertically downward. A protective cover 8 is slidably sleeved on the outer surface of the impact head 7. During detection, the impact head 7 is driven to move downward by the electric cylinder 5, and the physical properties are detected by the impact head 7 abutting against the curtain wall fixed below.
[0028] As Figure 2 shown, moving blocks 9 are respectively threadedly connected to the positive thread position 301 and the reverse thread position 302 of the positive and negative screw rod 3. The thread directions of the positive thread position 301 and the reverse thread position 302 of the positive and negative screw rod 3 are opposite and are located at both ends. In this way, when the positive and negative screw rod 3 rotates, the moving blocks 9 at both ends can be driven to move in opposite directions.
[0029] In this embodiment, sliding grooves 18 are respectively arranged on the front and rear sides of the workbench 1. The positive and negative screw rods 3 are respectively rotatably installed at the bottoms of the sliding grooves 18. The lower parts of the moving blocks 9 are located in the sliding grooves 18 on the workbench 1. During use, the moving blocks 9 can be driven to move along the sliding grooves 18 by the positive and negative screw rod 3. The top of the moving block 9 is fixedly connected with an L-shaped placing block 10. A concave surface 101 is arranged on the inner side edge of the L-shaped placing block 10. The concave surface 101 is used to support the side of the curtain wall. A power mechanism 11 and a flipping and pressing mechanism 12 are arranged on the top of the L-shaped placing block 10. The power mechanism 11 is connected to the flipping and pressing mechanism 12. The power mechanism 11 is used to drive the flipping and pressing mechanism 12, and the flipping and pressing mechanism 12 is used to press the curtain wall.
[0030] Refer to Figure 3 and 4, the power mechanism 11 includes a power cylinder 111 and a V-shaped linkage plate 112. The output end of the power cylinder 111 is fixedly connected to the middle of the V-shaped linkage plate 112. Both ends of the V-shaped linkage plate 112 are respectively fixedly connected with a U-shaped moving frame 113. Activity slots 114 are provided on both sides of the U-shaped moving frame 113. The activity slots 114 are in the shape of vertical long holes and are slightly inclined. A slider 115 is fixedly connected to the bottom of the U-shaped moving frame 113. The bottom of the slider 115 is slidably connected to a slide rail 116. The bottom of the slide rail 116 is fixedly connected to the top of the workbench 1.
[0031] During the use process, when the power cylinder 111 is started, it can drive the V-shaped linkage plate 112 to move, and the V-shaped linkage plate 112 drives the U-shaped moving frame 113 to move. Among them, the activity slots 114 are used to drive the activity column 125 to move. The cooperation of the slider 115 and the slide rail 116 can make the U-shaped moving frame 113 move more stably.
[0032] In this embodiment, two flipping and pressing mechanisms 12 are arranged side by side front and back on the L-shaped placing block 10. Refer to Figure 4 and 6 , the flipping and pressing mechanism 12 includes a flipping plate 121 and a pressing block 122. The pressing block 122 is fixedly connected to the lower part of the front end of the flipping plate 121 and is located above the concave surface 101. A central shaft 123 is movably arranged in the middle of the flipping plate 121. Both ends of the central shaft 123 are connected with a support plate 124. The bottom of the support plate 124 is fixedly connected to the top of the L-shaped placing block 10. The rear end of the flipping plate 121 is bent downward and is provided with an activity column 125. The horizontal position of the activity column 125 is lower than the horizontal position of the central shaft 123. Both ends of the activity column 125 respectively pass through the activity slots 114.
[0033] During the use process, the flipping plate 121 can be used to drive the pressing block 122 to flip and press. The flipping plate 121 flips along the central shaft 123. The support plate 124 is used to support the central shaft 123. The activity column 125 cooperates with the activity slots 114 to provide a flipping force for the flipping plate 121.
[0034] Refer to Figure 6 , both ends of the activity column 125 are respectively fixedly connected with a limit disc 13. The diameter of the limit disc 13 is larger than the diameter of the activity column 125 and the width of the activity slots 114. By setting the limit disc 13, the activity column 125 can be limited to prevent the activity column 125 from shifting during use.
[0035] Refer to Figure 5, a reinforcing sleeve 14 is fixedly connected to the output end of the power cylinder 111, and the reinforcing sleeve 14 is fixedly connected to the V-shaped linkage plate 112. By providing the reinforcing sleeve 14, the connection between the power cylinder 111 and the V-shaped linkage plate 112 can be strengthened, preventing loosening between the power cylinder 111 and the V-shaped linkage plate 112.
[0036] Reference Figure 6 , a pressing groove 15 is formed at the bottom of the pressing block 122. The number of pressing grooves 15 is several, and the several pressing grooves 15 are equidistantly distributed.
[0037] As a technical optimization scheme of the present utility model, by providing the pressing groove 15, the contact friction force with the surface of the object to be pressed can be increased, making the pressing effect more stable.
[0038] Reference Figure 1 , a reinforcing plate 16 is fixedly connected to the bottom outside the fixed frame 4, and the bottom of the reinforcing plate 16 is fixedly connected to the upper surface of the workbench 1.
[0039] As a technical optimization scheme of the present utility model, by providing the reinforcing plate 16, the fixed frame 4 can be strengthened, preventing the fixed frame 4 from shaking during use.
[0040] The working principle and usage process of the present utility model are as follows: As Figure 7 shown, when performing a physical property test on the curtain wall 17, the curtain wall 17 to be tested is placed between the L-shaped placement blocks 10. The two side edges of the curtain wall 17 are respectively supported on the concave surfaces 101. Then, the motor 2 drives the forward and reverse screw 3 to rotate. The forward and reverse screw 3 drives the moving blocks 9 on both sides and the L-shaped placement blocks 10 to move closer to each other, thereby clamping the curtain wall 17 to be tested. After that, the power cylinder 111 is started. The power cylinder 111 drives the V-shaped linkage plate 112 to move outward. The V-shaped linkage plate 112 drives the U-shaped moving frame 113 and the slider 115 to move outward along the slide rail 116. The movable groove 114 formed on the outside of the U-shaped moving frame 113 drives the movable column 125 to flip and move. The movable column 125 drives the flip plate 121 to flip inward along the central axis 123. The flip plate 121 drives the pressing block 122 to press on the upper surface of the curtain wall 17 to be tested. The curtain wall 17 to be tested is tightly fixed, and then the physical property test of the curtain wall 17 can be carried out.
[0041] In summary: The device for testing the physical properties of building curtain walls in this embodiment, through the combined use of the workbench 1, the motor 2, the forward and reverse screw 3, the fixed frame 4, the electric cylinder 5, the connecting plate 6, the impact head 7, the protective cover 8, the moving block 9, the L-shaped placement block 10, the power mechanism 11, and the flip pressing mechanism 12, can press the curtain wall 17 more efficiently and labor-savingly, saving the test time.
