DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] The European-style electric hoist anti-collision device of the utility model embodiment is described below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 4 As shown, the European-style electric hoist anti-collision device of the utility model embodiment may include an electric hoist body 10, a first anti-collision mechanism 20 and two second anti-collision mechanisms 30, wherein the first anti-collision mechanism 20 includes a limiting mechanism 21 and a buffer mechanism 22, wherein the limiting mechanism 21 is installed below the electric hoist body 10, and the buffer mechanism 22 is installed on the limiting mechanism 21.

[0025] It should be noted that the electric hoist body 10 described in this embodiment includes a wire rope 11, a hanger 12 and a hook 13. The wire rope 11 is connected to the hanger 12, and the hook 13 is connected to the hanger 12. By setting a buffer mechanism 22, the impact force received can be reduced when the limiting mechanism 21 collides with the electric hoist body 10.

[0026] The two second anti-collision mechanisms 30 are respectively arranged on both sides of the electric hoist body 10, and the second anti-collision mechanism 30 may include a mounting plate 31, two first damping shock absorbers 32 and an anti-collision plate 33, wherein the mounting plate 31 is connected to one side of the electric hoist body 10, the two first damping shock absorbers 32 are both connected to one side of the mounting plate 31, and the anti-collision plate 33 is connected to the two first damping shock absorbers 32.

[0027] It should be noted that, by providing the first damping shock absorber 32 and the anti-collision plate 33, the impact force generated when colliding with other electric hoists can be reduced, thereby protecting other electric hoists.

[0028] Specifically, in the actual operation process, by setting the buffer mechanism 22, the impact force can be reduced when the limiting mechanism 21 collides with the electric hoist body 10. By setting the first damping shock absorber 32 and the anti-collision plate 33, the impact force generated when colliding with other electric hoists can be reduced, thereby protecting other electric hoists.

[0029] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the limiting mechanism 21 may include two fixed plates 211, two rotating shafts 212, a fixed frame 213, a tilting frame 214 and a limiting plate 215, wherein the two fixed plates 211 are oppositely arranged on the bottom surface of the electric hoist body 10, the rotating shaft 212 is rotatably arranged on one side of the fixed plate 211, the fixed frame 213 is fixedly sleeved on the rotating shaft 212, the tilting frame 214 is connected to the fixed frame 213, and the limiting plate 215 is connected to the tilting frame 214.

[0030] It should be noted that when the electric hoist body 10 drives the hanging seat 12 to rise through the wire rope 11, the hanging seat 12 contacts the limiting plate 215. Due to the lever principle, the right end of the fixing frame 213 moves upward and the left end moves downward. The right end will hit the electric hoist body 10, thereby limiting the hanging seat 12.

[0031] In one embodiment of the present invention, Figure 2 As shown, the buffer mechanism 22 may include a plurality of anti-collision blocks 221 and an anti-collision plate 222 , wherein the plurality of anti-collision blocks 221 are connected to the top surface of the fixing frame 213 , and the anti-collision plate 222 is connected to the bottom surface of the limiting plate 215 .

[0032] It should be noted that the anti-collision block 221 and the anti-collision plate 222 described in this embodiment are both made of rubber material. By providing the anti-collision block 221, buffering can be performed when the fixing frame 213 collides with the electric hoist body 10. By providing the anti-collision plate 222, buffering can be performed when the limit plate 215 collides with the hanging seat 12, thereby protecting the electric hoist body 10.

[0033] In one embodiment of the present invention, Figure 4 As shown, the second anti-collision mechanism 30 may also include two vertical plates 34, a sliding rod 35, two sliders 36, two movable rods 37 and two second damping shock absorbers 38, wherein the two vertical plates 34 are connected to one side of the mounting plate 31, the sliding rod 35 is connected between the two vertical plates 34, the sliding rod 35 passes through and slidably connects the two sliders 36, the movable rod 37 is hinged between the slider 36 and the anti-collision plate 33, and the second damping shock absorber 38 is connected between the slider 36 and the vertical plate 34.

[0034] It should be noted that when the anti-collision plate 33 collides with other electric hoists, the movable rod 37 will move, thereby driving the slider 36 to move on the slide rod 35, and the second damping shock absorber 38 will buffer the slider 36, thereby further enhancing the buffering effect and achieving better anti-collision protection effect.

[0035] In one embodiment of the present invention, Figure 5 As shown, the first damping shock absorber 32 and the second damping shock absorber 38 may both include a damper 321 and a spring 322 , and the spring 322 is sleeved on the surface of the damper 321 .

[0036] It should be noted that the damper 321 and the spring 322 can be matched to effectively perform buffering and shock absorption.

[0037] In one embodiment of the present invention, Figure 6 As shown, fixing bolts 40 are threadedly connected on both sides of the mounting plate 31 , and the fixing bolts 40 are threadedly connected to the electric hoist body 10 .

[0038] It should be noted that the fixing bolts 40 are provided to facilitate installation and disassembly of the mounting plate 31 , thereby performing maintenance on the second anti-collision mechanism 30 .

[0039] Specifically, in the actual implementation process, when the electric hoist body 10 drives the hanging seat 12 to rise through the wire rope 11, the hanging seat 12 contacts the limiting plate 215. Due to the lever principle, the right end of the fixing frame 213 moves upward and the left end moves downward, and the right end will hit the electric hoist body 10, thereby limiting the hanging seat 12. By setting the anti-collision block 221, it can buffer when the fixing frame 213 collides with the electric hoist body 10. By setting the anti-collision plate 222, it can buffer when the limiting plate 215 collides with the hanging seat 12, thereby protecting the electric hoist body 10.

[0040] When the anti-collision plate 33 collides with other electric hoists, the first damping shock absorber 32 can reduce the impact force generated by the collision with other electric hoists, and the movable rod 37 will move, thereby driving the slider 36 to move on the slide rod 35. The second damping shock absorber 38 will buffer the slider 36, thereby further enhancing the buffering effect, making the anti-collision protection effect better and protecting other electric hoists.

[0041] In summary, the European-style electric hoist anti-collision device of the utility model embodiment can reduce the impact force received by the electric hoist body when a collision occurs by setting a first anti-collision mechanism and two second anti-collision mechanisms, thereby extending the service life of the electric hoist body and reducing the probability of safety accidents.
