wing type static testing machine

Abstract

This utility model provides a static testing machine for airfoils, belonging to the technical field of static testing equipment. It solves the problem of inconvenient operation of existing static testing equipment. The airfoil static testing machine includes a base, a foundation, mounting components, a display, a suspension mechanism, a steel wire rope, a hand-operated hoist, a pull rope, a force gauge, a support, and a scale. In this utility model, when the pull rope is pulled, it moves the steel wire rope, thereby moving the force gauge and suspension mechanism downwards. During this process, the airfoil is subjected to the traction force of the steel wire rope, causing it to bend. Simultaneously, the force gauge continuously monitors the traction force of the steel wire rope on the suspension mechanism and feeds this force back to the display. When the force applied to the pull rope reaches a predetermined value, the airfoil bends to a certain extent and then stops bending. Thus, the magnitude of the traction force can be changed at any time according to testing needs without changing the load, making operation convenient.

[0005] A base, wherein a pedestal is provided on the base, and a mounting assembly for mounting wing products is provided on the pedestal, and a display is provided inside the pedestal;

[0006] A suspension mechanism is suspended from the wing-shaped product. A steel wire rope is connected to the bottom of the suspension mechanism. After passing the top surface of the base, the steel wire rope changes direction to the bottom surface of the base. A hand-operated hoist is installed on the bottom surface of the base. A pull rope is installed on the hand-operated hoist. One end of the pull rope is connected to one end of the steel wire rope. The steel wire rope and the suspension mechanism are connected through a tension gauge. The tension gauge is electrically connected to a display.

[0007] At least one support is provided on the base, and the support is provided with a scale for measuring the bending amplitude of the wing product.

[0008] In the aforementioned airfoil static testing machine, the base is provided with a first guide wheel and a second guide wheel, and the steel wire rope passes around the first guide wheel and the second guide wheel in sequence. The first guide wheel is located directly below the suspension mechanism, and the second guide wheel is located inside the base and below.

[0009] In the aforementioned wing static testing machine, the base is provided with a disassembly plate, and a disassembly seat for installing the first guide wheel is detachably connected to the disassembly plate.

[0010] In the aforementioned wing static testing machine, the mounting assembly includes a mounting plate located on top of the base, a mounting platform connected to the mounting plate, and a connecting ring and a pressure plate for mounting wing products on the mounting platform. The pressure plate and the connecting ring are connected by bolts.

[0011] In the aforementioned static testing machine for wing-like structures, the diameter of the connecting ring is the same as the diameter of the bottom end of the pressure table, and the diameter of the top end of the pressure table is larger than the diameter of the bottom end of the pressure table.

[0012] In the aforementioned static testing machine for airfoils, the connecting ring is coaxially arranged with the pressure table, the bottom surface of the mounting platform is provided with multiple sliders, the mounting plate is provided with multiple sliding grooves, and the sliders are slidably engaged in the corresponding sliding grooves.

[0013] In the aforementioned airfoil static testing machine, the suspension mechanism includes multiple suspension plates suspended on the airfoil product and at least two extension components. Adjacent suspension plates may or may not be connected by a connecting component. One end of the uppermost extension component is connected to one of the suspension plates or the connecting component, and one end of the remaining extension components is connected to the extension component of the previous layer. The other end of each extension component is connected to the corresponding suspension plate or the connecting component.

[0014] In the aforementioned wing static testing machine, each of the extension components includes an extension plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, when a person pulls the pull rope, the pull rope will drive the steel wire rope to move, thereby causing the tension gauge and suspension mechanism to move downward. During this process, the wing-like product is subjected to the traction force of the steel wire rope, causing the wing-like product to bend. At the same time, the tension gauge will constantly detect the traction force of the steel wire rope on the suspension mechanism and feed the traction force back to the display. In this way, people can accurately control the magnitude of the traction force according to the value displayed on the display. When the force applied to the pull rope reaches the predetermined value, the wing-like product bends to a certain extent and then stops bending.

[0022] Figure 4 This is a schematic diagram of the suspension mechanism. Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1 — Figure 4 As shown, the static testing machine for wing-type objects of this utility model includes a base 100, a base 200, an installation assembly 300, a display 210, a suspension mechanism 400, a wire rope 410, a hand chain hoist 220, a pull rope 221, a tension gauge 420, and a support 110.

[0025] A base 200 is provided on the base 100. A mounting assembly 300 for mounting wing-like products is provided on the base 200. A display 210 is located inside the base 200. A suspension mechanism 400 is suspended from the wing-like products. A steel wire rope 410 is connected to the bottom of the suspension mechanism 400. The steel wire rope 410 passes over the top surface of the base 100 and then reverses direction to the bottom surface of the base 200. A hand-operated hoist 220 is provided on the bottom surface of the base 200. A pull rope 221 is provided on the hand-operated hoist 220. One end of the pull rope 221 is connected to one end of the steel wire rope 410. The steel wire rope 410 is connected to the suspension mechanism 400 via a tension gauge 420, which is electrically connected to the display 210. At least one A bracket 110 is mounted on a base 100. The bracket 110 has a scale (not shown in the figure) for measuring the bending amplitude of the wing-like product. During static testing of the wing-like product, one end is mounted to the base 200 via the mounting assembly 300. The wing-like product will then align with a specific mark on the scale (not shown in the figure), which is recorded and designated as the first mark. Next, the suspension mechanism 400 is suspended from the wing-like product, and the end of the wire rope 410 away from the hand-operated hoist 220 is connected to the bottom of the suspension mechanism 400 via a force gauge 420. Thus, when the pull rope 221 is pulled, it causes the wire rope 410 to move, thereby... As the force gauge 420 and suspension mechanism 400 move downwards, the wing-like product is subjected to the traction force of the steel wire rope 410, causing it to bend. Simultaneously, the force gauge 420 continuously monitors the traction force of the steel wire rope 410 on the suspension mechanism 400 and feeds this force back to the display 210. Users can then precisely control the magnitude of this traction force based on the values ​​displayed on the display 210. When the force applied to the pull rope 221 reaches a predetermined value, the wing-like product bends to a certain extent and then stops bending. At this point, the wing-like product aligns with another scale (not shown in the diagram), and this scale is recorded and designated as the second scale. The value of the second scale is then subtracted from the value of the first scale. By measuring the degree of bending, the bending amplitude of the wing product can be calculated, which means the deformation of the wing product can be measured. Furthermore, during the static test, the forces applied to the wing product include the traction force of the steel wire rope 410 on the wing product and the weight of the suspension mechanism 400 and the tension gauge 420. The weight of the steel wire rope 410 is relatively light and can be ignored. In addition, the bottom of the support 110 is provided with multiple suction cups (not shown in the figure), which can be attached to the top surface of the base 100, so that the support 110 can be moved on the base 100. In addition, in this utility model, the wing product is mounted on the base through the mounting component 300, so that the testing machine can be applied to different types of wing products.

[0026] In this utility model, when people pull the pull rope 221, the pull rope 221 can only move towards the end of the hand chain hoist 220 away from the wire rope 410. When people remove the pulling force acting on the pull rope 221, the hand chain hoist 220 will restrict the pull rope 221 from moving in the opposite direction, so that the wire rope 410 can maintain the traction force on the suspension mechanism 400 and the wing-like product. In addition, the hand chain hoist 220 restricting the reverse movement of the pull rope 221 is prior art, so it is not described in detail in this utility model.

[0027] The base 100 is provided with a first guide wheel 120 and a second guide wheel 130. The steel wire rope 410 passes around the first guide wheel 120 and the second guide wheel 130 in sequence. The first guide wheel 120 is located directly below the suspension mechanism 400, and the second guide wheel 130 is located inside the base 200. By setting the first guide wheel 120 and the second guide wheel 130, the direction of the steel wire rope 410 can be reversed.

[0028] The base 100 is provided with a disassembly plate 140, and a disassembly seat 121 for installing the first guide wheel 120 is detachably connected to the disassembly plate 140. During installation, the disassembly seat 121 needs to be connected to the disassembly plate 140 by bolts 324, so that the disassembly seat 121 can be detachably connected to the disassembly plate 140. In this way, the disassembly seat 121 can be moved to the bottom of the suspension mechanism 400 so that the wire rope 410 can be reversed smoothly.

[0029] The mounting assembly 300 includes a mounting plate 310 disposed on the top of the base 200. A mounting platform 320 is connected to the mounting plate 310. The mounting platform 320 is provided with a connecting ring 322 and a pressure plate 323 for mounting wing-like products. The connecting ring 322 and the pressure plate 323 are coaxially arranged. The pressure plate 323 and the connecting ring 322 are connected by bolts 324. The end of the wing-like product is provided with a mounting hole (not shown in the figure). When installing the wing-like product, the mounting hole of the wing-like product needs to be aligned with the connecting ring 322 and the connecting ring 322 needs to be inserted into the mounting hole. Then, one end of the pressure plate 323 needs to be inserted into the mounting hole until one end of the pressure plate 323 contacts the connecting ring 322. After that, the pressure plate 323 and the connecting ring 322 are connected by bolts 324. In this way, the wing-like product can be mounted on the mounting plate 310.

[0030] Furthermore, the diameter of the connecting ring 322 is the same as the diameter of the bottom end of the pressing table 323, the diameter of the top end of the pressing table 323 is larger than the diameter of the bottom end of the pressing table 323, the diameter of the mounting hole is larger than the diameter of the bottom end of the pressing table 323, and the diameter of the mounting hole is smaller than the diameter of the top end of the pressing table 323. Through this structure, the pressing table 323 can stably press the wing-like product onto the mounting plate 310.

[0031] The mounting platform 320 has multiple sliders 321 on its bottom surface. These sliders are inverted T-shapes. The mounting plate 310 has multiple grooves 311. The sliders 321 are slidably engaged in the corresponding grooves 311. During installation, the corresponding groove 311 is selected according to the installation requirements, and the sliders 321 are installed into the corresponding grooves 311. Then, the mounting platform 320 is moved relative to the mounting plate 310 so that the position of the mounting platform 320 on the mounting plate 310 meets the installation requirements of the wing-type product. When the wing-type product is installed on the mounting assembly, the mounting platform is subjected to the force of the wing-type product, and the friction between the slider and the top surface of the groove will increase, thereby restricting the movement of the slider in the groove. Furthermore, bolts can be installed at the four corners of the mounting platform, and the bottom end of the bolts can be pressed against the mounting plate. Since the slider is then slidably engaged in the groove, the friction between the slider and the groove can be strengthened, further preventing the slider from moving in the groove.

[0032] The suspension mechanism 400 includes multiple suspension plates 430 suspended on the wing-like product and at least two extension components 440. Adjacent suspension plates 430 may or may not be connected by a connecting component 450. One end of the uppermost extension component 440 is connected to the leftmost suspension plate 430 or the connecting component 450. The left ends of the remaining extension components 440 are connected to the extension components 440 above them. The other end of each extension component 440 is connected to the corresponding suspension plate 430 or the connecting component 450. By setting at least two extension components 440, the centers of the multiple suspension plates 430 can be gradually brought together. Thus, when a person applies traction force to the bottommost extension component 440, the applied traction force will be successfully applied to each suspension plate 430.

[0033] Furthermore, each of the extension components 440 includes an extension plate 441. The length of each extension plate 441 may be the same or different. One end of the extension plate 441 is provided with a left connecting rod 441a, which is connected to the bottom of the upper layer extension plate 441. The left connecting rod 441a of the uppermost extension component 440 is connected to the leftmost suspension plate 430 or the connecting component 450. The other end of the extension plate 441 is provided with a right connecting rod 441b, which is connected to the suspension plate 430 or the connecting component 450 located directly above the right connecting rod 441b. The lowermost extension plate 441 is provided with a suspension rod 442 for connecting the tension gauge 420. During installation, people can select an extension plate 441 of appropriate length according to the actual installation requirements so that the left connecting rod 441a on the next layer extension component 440 can be smoothly connected to the extension plate 441 of that layer.

[0034] Each of the connecting components 450 includes a connecting plate 451, and each end of the connecting plate 451 is provided with a connecting rod 452 for connecting the corresponding suspension plate 430. Through the setting of the connecting component 450, two adjacent suspension plates 430 can be connected together, so that the center of the two suspension plates 430 is brought together to form the center of the connecting plate 451. During the installation process, the left connecting rod 441a or the right connecting rod 441b is connected to the center of the connecting plate 451, the left connecting rod 441a is connected to the center of the upper layer extension plate 441, and the suspension rod 442 is located at the center of the lowest layer extension plate 441.

[0035] A protective net 230 is provided on the side of the base 200 facing the suspension mechanism 400. By setting up the protective net 230, the interior of the base 200 can be blocked from the side of the base 200 facing the suspension mechanism 400. In this way, when the suspension mechanism 400 falls from the wing product, the protective net 230 can block the suspension mechanism 400 or the force gauge 420, thereby preventing the suspension mechanism 400 or the force gauge 420 from hitting people and improving safety.

[0036] The base 200 is provided with a footboard 240 and a guardrail 250 on the top of the base 200. The base 200 is also provided with a ladder 260. When the suspension mechanism 400 is suspended on the wing product, people can step on the footboard 240 for easy operation.
