Description

Technical Field

[0001] The invention belongs to the technical field of aerial vehicles, and in particular to a deformation monitoring device for an aerial vehicle frame. Background Art

[0002] A trolley is a kind of lifting equipment, which is basically the same as what we call a crane. There are basically two types of trolley driving methods: one is centralized driving, that is, a motor drives a long transmission shaft to drive the active wheels on both sides; the other is separate driving, that is, the active wheels on both sides are driven by a motor each. The existing trolley support frame structure lacks a device to monitor the trolley frame part when the trolley support frame is severely deformed or collapsed, and a safety warning cannot be achieved. Summary of the invention

[0003] The object of the present invention is to provide a vehicle frame deformation monitoring device to solve the problems raised in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for monitoring deformation of an aerial vehicle frame, comprising an aerial vehicle frame and an aerial vehicle load-bearing bracket at the bottom of both ends of the aerial vehicle frame, two fixing seats being fixedly connected to the middle position of the bottom of the aerial vehicle frame, a connecting block being fixedly connected to the side of the bottom of the aerial vehicle frame away from the two fixing seats, and a traction rod being arranged between the connecting block and the corresponding fixing seat, the fixing seat being provided with a cavity, and a sliding seat being limitedly slidably arranged on the inner periphery of the cavity, two side plates being connected to the top of the sliding seat and the bottom of the connecting block, and the two side plates being hinged to one end corresponding to the traction rod, an audible and visual warning device being installed on one side of the fixing seat, and a power-on end of the audible and visual warning device being connected to a push button switch through wiring.

[0005] In a further embodiment, a limiting sliding groove is provided at the bottom of the cavity, and a limiting sliding block adapted to the limiting sliding groove is connected to the bottom of the sliding seat.

[0006] In a further embodiment, the button switch is disposed on one side of the inner wall of the cavity, and a pressing plate is connected to a side of the sliding seat close to the button switch.

[0007] In a further embodiment, both ends of the traction rod are provided with an arc-shaped design, and a center hole is opened in the center of both ends of the traction rod.

[0008] In a further embodiment, a side of the inner wall of the cavity away from the pressing plate is connected to a solid sleeve, and a tenon rod is provided on one side of the solid sleeve.

[0009] In a further embodiment, one end of the tenon rod is located at the inner circumference of the solid sleeve and is provided with a blocking portion, and a compression spring is provided on one side of the blocking portion.

[0010] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0011] The two connecting blocks and the fixed seat at the bottom of the vehicle frame adopt a traction rod connection design and the limited sliding of the sliding seat. When the frame is deformed, the distance between the connecting block and the fixed seat will increase, further driving the sliding seat to slide; the sound and light alarm design on the top of the fixed seat and the connection design between the sound and light alarm and the button switch, when the sliding seat moves, the button switch can be pressed, thereby playing an alarm role. At the same time, the support design of the sliding seat and the traction rod can further achieve a supporting role in times of crisis and increase the escape time;

[0012] The vehicle frame deformation monitoring device can not only provide deformation warning and improve the safety of use, but also play a role in strengthening support and improving structural safety in times of crisis. BRIEF DESCRIPTION OF THE DRAWINGS

The trolley load-bearing bracket 12 in the factory is provided with a track, and the trolley frame 11 is erected on the track. The trolley load-bearing bracket 12 and the trolley frame 11 are designed to be movable and matched. The above is the general structure of the existing trolley in the factory, which is the existing technology, so it will not be repeated;

[0023] Two fixing seats 1 are fixedly connected at the middle of the bottom of the vehicle frame 11.

[0024] A connecting block 3 is provided at the bottom of the vehicle frame 11 on one side away from the two fixing seats 1. The connecting block 3 is connected to the vehicle frame 11 by screws. A cavity 2 is provided in the fixing seat 1. A sliding seat 6 is provided on the inner periphery of the cavity 2 for limited sliding. A limited sliding groove 21 is provided at the bottom of the cavity 2. A limited sliding block 22 adapted to the limited sliding groove 21 is connected to the bottom of the sliding seat 6. Two side plates 7 are connected to the bottom of the sliding seat 6 and the bottom of the connecting block 3. A traction rod 4 is provided between the connecting block 3 and the corresponding fixing seat 1.

[0025] Both ends of the traction rod 4 are provided with an arc-shaped design, and both ends of the traction rod 4 are provided with a central hole, and the central hole and the corresponding two side plates 7 are hinged by a latch;

[0026] See also Figures 1 to 3 In order to realize the alarm, a sound and light warning device 8 is installed on one side of the fixing base 1, and the power-on end of the sound and light warning device 8 is connected to a button switch 9 through wiring.

[0030] Working principle:

[0031] The vehicle frame deformation monitoring device, when the vehicle frame 11 is deformed, the vehicle frame 11 bends downward and deforms and extends, so that the distance between the connecting block 3 and the fixing seat 1 increases, and the connecting block 3 causes the traction rod 4 to move synchronously toward the connecting block 3, further causing the sliding seat 6 to move;

[0032] The pressing plate 10 is driven to move and the button switch 9 is pressed to start the sound and light warning device 8, thereby serving as a reminder. At the same time, the traction rod 4 can temporarily strengthen the support of the frame, thereby increasing the escape time.
