Description

Technical Field

[0001] This application relates to the field of lifting hooks, and more specifically, to a load-monitoring automatic release device and system for training equipment. Background Technology

[0002] When conducting external cargo hook deployment training during helicopter hovering and rescue training, due to the high cost of helicopter-equipped external cargo hooks, it is necessary to design a simple automatic release device for training.

[0003] Currently available electric automatic detachment devices typically detach by cutting the connecting rope with a cutter. This not only results in significant rope waste, but also frequent rope replacements are unsuitable for routine helicopter hovering and rescue training. Furthermore, the automatic detachment devices lack load detection, posing a risk during training. Utility Model Content

[0004] The purpose of this application is to provide a load monitoring type automatic disengagement device and system for training equipment, which eliminates material loss and improves training efficiency, while being able to detect the load size during disengagement training and avoid undetected safety risks during training.

[0005] This application is implemented as follows: This application provides a load monitoring type automatic release device for training equipment, which includes a self-weighing upper connecting plate and a self-weighing lower connecting plate arranged at intervals, at least one tension sensor with its top and bottom respectively connected to the self-weighing upper connecting plate and the self-weighing lower connecting plate, and a hook shaft side plate connected to the bottom of the self-weighing lower connecting plate. The self-weighing lower connecting plate is connected to an electric push rod. A hook is hinged to the lower part of the hook shaft side plate. One end of a release rocker arm is hinged to the middle part of the hook shaft side plate. The other end of the release rocker arm is hinged to a swing arm connecting rod. The middle part of the release swing arm is hinged to the upper part of the hook shaft side plate. The two ends of the release swing arm are respectively hinged to the telescopic rod of the electric push rod and the swing arm connecting rod. When the telescopic rod of the electric push rod extends or retracts, it drives the release rocker arm to rotate counterclockwise or clockwise through the release swing arm and the swing arm connecting rod, so that the release rocker arm rotates to release and stop limiting the rotation of the hook or presses against and limiting the rotation of the hook.

[0006] In some alternative implementations, a swing arm link spring is connected between the hook shaft side plate and the swing arm link and the hinged end of the unhooking swing arm.

[0007] In some alternative implementations, a hook spring is connected between the hinged end of the hook and the hook shaft side plate.

[0008] In some alternative implementations, a sensor limiting plate is also provided between the self-weighing upper connecting plate and the self-weighing lower connecting plate, the sensor limiting plate being used to limit the position of the tension sensor.

[0009] In some alternative implementations, the bottom of the self-weighing lower connecting plate is connected to a hook side plate mounting plate, the top of the hook shaft side plate is connected to the hook side plate mounting plate, the hook side plate mounting plate is connected to an electric push rod mounting seat, and the electric push rod is connected to the electric push rod mounting seat.

[0010] This application also provides a load monitoring type automatic release system for training equipment, which includes a self-weighing housing and the aforementioned load monitoring type automatic release device for training equipment connected within the self-weighing housing. The bottom of the hook shaft side plate and the hook extend out of the bottom of the self-weighing housing, and the top of the self-weighing upper connecting plate is connected to a self-weighing lifting lug seat that extends out of the top of the self-weighing housing.

[0011] In some alternative implementations, the self-weighing lifting lug is connected to multiple double-hole lifting lugs via double-groove pins, each double-hole lifting lug is connected to a wire rope hook via a wire rope, and each wire rope hook is connected to a fixed angle seat.

[0012] In some alternative implementations, the two ends of the wire rope are connected to a double-hole lifting lug and a fixed angle bracket respectively via a double-ear rod welded assembly.

[0013] In some alternative implementations, the top surface of the self-weighing housing is provided with a display screen that is electrically connected to each of the tension sensors.

[0014] In some alternative implementations, a protective fence is also included that is fitted over the outside of the self-weighing enclosure.

[0015] The beneficial effects of this application are as follows: The training equipment using a load monitoring type automatic disengagement device and system provided by this application is equipped with an electric push rod that extends and retracts, driving the disengagement rocker arm to rotate counterclockwise or clockwise through the disengagement swing arm and the swing arm connecting rod. This causes the disengagement rocker arm to rotate until it disengages and stops, limiting the rotation of the hook or pressing and limiting the rotation of the hook. This can stably drive the hook to rotate and limit the rotation of the hook to achieve disengagement training, eliminating material waste and improving training efficiency. At the same time, by setting a tension sensor connected to the self-weighing upper connecting plate and the self-weighing lower connecting plate for self-weighing, the load size during disengagement training can be detected in a timely manner, avoiding undetected safety risks during training.

[0027] like Figure 1 and Figure 2 As shown, this application provides a load-monitoring automatic disengagement system for training equipment, which includes a self-weighing housing 300 and a load-monitoring automatic disengagement device for training equipment connected within the self-weighing housing 300; as Figure 2As shown, the load monitoring type automatic release device for training equipment includes a self-weighing upper connecting plate 100 and a self-weighing lower connecting plate 110 arranged at intervals, two symmetrically arranged tension sensors 120, and a hook side plate mounting plate 220 welded to the bottom of the self-weighing lower connecting plate 110. The top and bottom of the tension sensor 120 are connected to the self-weighing upper connecting plate 100 and the self-weighing lower connecting plate 110 respectively by sensor connecting screws 240. Three sensor limiting plates 210 are provided between the self-weighing upper connecting plate 100 and the self-weighing lower connecting plate 110. The two sides of each sensor limiting plate 210 are used to press and limit the position of the two tension sensors 120 respectively.

[0028] A hook shaft side plate 130 is welded to the bottom of the hook side plate mounting plate 220. An L-shaped electric push rod mounting seat 230 is connected to one side of the hook side plate mounting plate 220. An electric push rod 140 is welded to the electric push rod mounting seat 230. The lower part of the hook shaft side plate 130 is hinged to the top of the hook 150 via a hook pin 151. The middle part of the hook shaft side plate 130 is hinged to one end of a release rocker arm 160 via a rocker arm pin 161. The other end of the release rocker arm 160 is hinged to one end of a swing arm connecting rod 170 via a first intermediate pin 250. The upper part of the hook shaft side plate 130 is hinged to the middle of the L-shaped release swing arm 180 via a rocker arm pin 181. The two ends of the hook swing arm 180 are respectively hinged to the telescopic rod of the electric push rod 140 and the other end of the swing arm connecting rod 170 through the second intermediate pin 260; when the telescopic rod of the electric push rod 140 extends or retracts, it drives the hook release rocker arm 160 to rotate counterclockwise or clockwise through the hook release swing arm 180 and the swing arm connecting rod 170, so that the hook release rocker arm 160 rotates to disengage and stop limiting the rotation of the hook 150 or presses against and limiting the rotation of the hook 150; a swing arm connecting rod spring 190 is connected between the hook shaft side plate 130 and the hinged end of the swing arm connecting rod 170 and the hook release swing arm 180, and a hook spring 200 is connected between the hinged end of the hook 150 and the hook shaft side plate 130 and the hook shaft side plate 130.

[0029] The bottom of the hook shaft side plate 130 and the hook 150 extend out of the bottom of the self-weighing cover 300. The top of the self-weighing upper connecting plate 100 is connected to a self-weighing lifting lug 310 that extends out of the top of the self-weighing cover 300. The top and bottom of the self-weighing cover 300 are respectively provided with openings for the hook shaft side plate 130, the hook 150, and the self-weighing lifting lug 310 to extend out. The self-weighing lifting lug 310 is connected to four double-hole lifting lugs 330 through a double-groove pin 320. Each double-hole... Each of the lifting lugs 330 is connected to a steel wire rope 340 via a double lug welded assembly 370. The ends of the four steel wire ropes 340 away from the double-hole lifting lugs 330 are respectively connected to steel wire rope hooks 350 via the double lug welded assembly 370. Each steel wire rope hook 350 is connected to a fixed corner seat 360. The top surface of the self-weighing cover 300 is provided with a display screen 380 that is electrically connected to two tension sensors 120. A protective fence 390 is provided on the outside of the self-weighing cover 300.

[0030] The working principle of the automatic disengagement system for training equipment with load monitoring provided in this application embodiment is as follows: Before use, the automatic disengagement device for training equipment with load monitoring is connected to the self-weighing housing 300. Then, the automatic disengagement system for training equipment with load monitoring is installed in the training helicopter simulator. The fixed angle brackets 360 connected to the top of the four steel wire ropes 340 through the steel wire rope hooks 350 are respectively fixed to the top wall of the helicopter simulator. The bottom double-hole lifting lugs 330 and self-weighing lifting lugs 310, as well as the automatic disengagement device for training equipment with load monitoring and the self-weighing housing 300, are suspended and fixed in the air by the four steel wire ropes 340. Then, the protective fence 390 is installed on the outside of the automatic disengagement device for training equipment with load monitoring and the self-weighing housing 300 for protection. Then, disengagement training can be carried out. During disengagement training, the telescopic rod of the electric push rod 140 is extended downward, so that the electric push rod 140... The telescopic rod drives the hinged release arm 180 to rotate counterclockwise. When the release arm 180 rotates counterclockwise, it drives the arm linkage 170 to move and pulls up the arm linkage spring 190. When the arm linkage 170 moves, it drives the release rocker arm 160 to rotate counterclockwise and stop pressing against the top position of the hook 150. At this time, the hook 150 rotates clockwise due to gravity and falls to perform the release action and stretches the hook spring 200; the telescopic rod 140 controls the extension and retraction of the hook. The rod retracts upward, causing the telescopic rod of the electric push rod 140 to drive the hinged hook release arm 180 to rotate clockwise. When the hook release arm 180 rotates clockwise, it drives the arm linkage 170 to move and causes the arm linkage spring 190 to reset. When the arm linkage 170 moves, it drives the hook release rocker arm 160 to rotate clockwise, pressing against the top of the hook 150 and limiting the position of the hook 150. At the same time, the hook spring 200 resets and locks the position of the hook 150 so that it cannot move.

[0031] Furthermore, the tension sensor 120 connected between the upper self-weighing connecting plate 100 and the lower self-weighing connecting plate 110 can detect the downward tension load of the hook 150 connected to the lower self-weighing connecting plate 110 in real time, and transmit the tension load detected by the tension sensor 120 to the display screen 380 on the top surface of the self-weighing housing 300 for display by the operators, so as to avoid safety hazards caused by problems during the test. A sensor limiting plate 210 is provided between the upper self-weighing connecting plate 100 and the lower self-weighing connecting plate 110. The two sides of the sensor limiting plate 210 are used to press and limit the position of the two tension sensors 120, which can prevent the tension sensors 120 from moving in the horizontal direction and affecting the detection accuracy.

[0032] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
