[0024] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.
[0025] As Figure 1 shown, an anti-collision device for construction machinery with high stability includes a mounting block 1. A first anti-collision device 2 is provided on the mounting block 1. A second anti-collision device 3 and a warning device 4 are provided on the first anti-collision device 2. The first anti-collision device 2 cooperates with the second anti-collision device 3 to prevent collisions of the construction machinery, and the warning device 4 gives a warning when a collision occurs.
[0026] In the present utility model, by providing two groups of anti-collision devices, the structure is simple, and it can prevent external vertical collisions and inclined collisions, and give a warning prompt in time after a collision. The management personnel make a treatment according to the warning prompt, and then manually reset the warning prompt, and the anti-collision device can continue to carry out anti-collision warning.
[0027] As Figure 2 and Figure 4As shown, the mounting block 1 has an H-shaped structure. Mounting through holes are provided at the upper and lower ends of one side of the mounting block 1, and the first anti-collision device 2 is arranged on the side wall at the other end of the mounting block 1.
[0028] By setting the mounting block 1, it can be installed outside the construction machinery in cooperation with the vertical pole, and can also be directly installed on the outer surface of the construction machinery through the mounting through holes in cooperation with bolts.
[0029] As Figure 3 and Figure 4 As shown, the first anti-collision device 2 includes an anti-collision seat 201 arranged on the side wall at the other end of the mounting block 1. The anti-collision seat 201 is integrally tubular. The connection end of the anti-collision seat 201 with the mounting block 1 is a closed end, and the other end of the anti-collision seat 201 is an open end. Four first springs 202 are provided on the inner wall of the anti-collision seat 201, and the four first springs 202 are evenly distributed at equal angles around the central axis of the anti-collision seat 201; the second anti-collision device 3 includes an anti-collision disc 301 arranged at the end of the first spring 202. The outer wall of the anti-collision disc 301 fits with the inner wall of the anti-collision seat 201, and the anti-collision disc 301 slides horizontally back and forth inside the anti-collision seat 201; the inside of the anti-collision disc 301 is hollow, and a circular through hole is provided on the side of the anti-collision disc 301. The inner diameter of the circular through hole is one-third of the inner diameter of the anti-collision disc 301. A damping disc 302 is movably arranged inside the anti-collision disc 301, and the inner diameter of the damping disc 302 is two-thirds of the inner diameter of the anti-collision disc 301; a second spring 303 is provided between the outer wall of the damping disc 302 and the inner wall of the anti-collision disc 301. An installation rod 304 is provided in the middle of the damping disc 302. The installation rod 304 passes through the circular through hole, and an anti-collision plate 305 is provided at the end of the installation rod 304. The size of the anti-collision plate 305 is larger than the size of the anti-collision seat 201, and the corners of the anti-collision plate 305 are rounded.
[0030] As Figure 3 and Figure 4 As shown, in actual use, when a vertical collision occurs, when the anti-collision plate 305 contacts an external force, the anti-collision plate 305 squeezes the installation rod 304, the installation rod 304 squeezes the damping disc 302, the damping disc 302 squeezes the anti-collision disc 301, the anti-collision disc 301 slides horizontally inside the anti-collision seat 201, and the anti-collision disc 301 squeezes the first spring 202. Under the buffering action of the first spring 202, the anti-collision effect is achieved;
[0031] As Figure 3 and Figure 4As shown in the figure, when a side collision occurs, when the anti-collision plate 305 contacts an external force, the anti-collision plate 305 squeezes the mounting rod 304, and the mounting rod 304 squeezes the damping disc 302. At this time, the damping disc 302 slides horizontally inside the anti-collision disc 301, and the damping disc 302 squeezes the second spring 303. Under the buffering action of the second spring 303, side anti-collision is achieved. Specifically, when a collision occurs in the inclined direction, according to the orthogonal decomposition of the force, the collision force is decomposed into a direction perpendicular to the anti-collision plate 305 and a direction parallel to the anti-collision plate 305. Therefore, under the simultaneous buffering action of the first spring 202 and the second spring 303, anti-collision in the inclined direction is achieved.
[0032] As Figure 2 and Figure 3 shown in the figure, the warning device 4 includes a third spring 401 arranged at the middle position inside the anti-collision seat 201. The end of the third spring 401 is provided with a first button switch 402, and a second button switch 403 and a warning horn 404 are arranged outside the anti-collision seat 201.
[0033] It should be noted that the first button switch 402 and the second button switch 403 are existing parts through procurement activities, and the structures of the first button switch 402 and the second button switch 403 will not be elaborated here.
[0034] As Figure 5 shown in the figure, Figure 5 is the wiring schematic diagram of the first button switch 402 and the second button switch 403 in the initial state. In actual use, when an inclined collision occurs, the anti-collision disc 301 slides inward inside the anti-collision seat 201. At this time, the anti-collision disc 301 presses the first button switch 402. Specifically, the wiring knife of the first button switch 402 changes from point d to point c. At this time, the circuit is turned on. Then, when the first button switch 402 is pressed, the warning horn 404 issues a warning prompt. After the management personnel make a response according to the warning prompt, they manually press the second button switch 403. At this time, the wiring knife of the second switch 402 changes from point a to point b, and the circuit is disconnected again, and the warning horn 404 stops making a sound, manually resetting the warning prompt. When a collision occurs again, the anti-collision disc 301 presses the first button switch 402. Specifically, the wiring knife of the first button switch 402 changes from point c to point d. At this time, the circuit is turned on. Then, when the first button switch 402 is pressed, the warning horn 404 issues a warning prompt. After the management personnel make a response according to the warning prompt, they manually press the second button switch 403. At this time, the wiring knife of the second switch 402 changes from point b to point a, and the circuit is disconnected again, and the warning horn 404 stops making a sound, manually resetting the warning prompt. Finally, every time a collision occurs, the warning horn 404 issues a warning prompt, and then after manual processing and recovery, the warning horn 404 stops issuing the warning prompt.
[0035] The total length of the fully contracted length of the third spring 401 plus the length of the first button switch 402 is less than the fully contracted length of the first spring 202.
[0036] In the present utility model, since the total length of the fully contracted length of the third spring 401 plus the length of the first button switch 402 is less than the fully contracted length of the first spring 202, when the anti-collision disc 301 slides to the bottommost part of the anti-collision seat 201, the first button switch 402 will not be violently squeezed, enabling the first button switch 402 to be used normally and avoiding circuit failures.
[0037] As Figures 1-5 shown, the working principle of the present utility model is as follows: By setting the mounting block 1, it can be installed outside the construction machinery in cooperation with the vertical rod, and can also be directly installed on the outer surface of the construction machinery through the mounting through holes in cooperation with bolts; when a vertical collision occurs, when the anti-collision plate 305 contacts an external force, the anti-collision plate 305 squeezes the mounting rod 304, the mounting rod 304 squeezes the damping disc 302, the damping disc 302 squeezes the anti-collision disc 301, the anti-collision disc 301 slides horizontally inside the anti-collision seat 201, the anti-collision disc 301 squeezes the first spring 202, and under the buffering effect of the first spring 202, an anti-collision effect is achieved;
[0038] When a side collision occurs, when the anti-collision plate 305 contacts an external force, the anti-collision plate 305 squeezes the mounting rod 304, the mounting rod 304 squeezes the damping disc 302. At this time, the damping disc 302 slides horizontally inside the anti-collision disc 301, and the damping disc 302 squeezes the second spring 303. Under the buffering effect of the second spring 303, side anti-collision is realized; specifically, when a collision occurs in an inclined direction, according to the orthogonal decomposition of the force, the collision force is decomposed into a direction perpendicular to the anti-collision plate 305 and a direction parallel to the anti-collision plate 305. Therefore, under the simultaneous buffering effect of the first spring 202 and the second spring 303, anti-collision in the inclined direction is achieved; when an inclined collision occurs, the anti-collision disc 301 slides inward inside the anti-collision seat 201. At this time, the anti-collision disc 301 presses the first button switch 402. After the first button switch 402 is pressed, the warning horn 404 issues a warning prompt. After the management personnel make a response based on the warning prompt, they then manually press the second button switch 403, and the warning horn 404 stops emitting sound, manually resetting the warning prompt. The anti-collision device can continue to perform anti-collision warnings. Specifically, when the anti-collision disc 301 presses the first button switch 402 again, the warning horn 404 can still issue a warning prompt.
[0039] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
