[0039] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.
[0040] First, a crane according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.
[0041] like Figure 1 and Figure 2As shown, the crane of the embodiment of the present invention may include: a rear beam 100, a car stop 200, a bracket trolley maintenance platform 300, an anti-hooking round pipe 400 and a main trolley 500. The length direction of the rear beam 100 is consistent with the first direction; the length direction of the car stop 200 is consistent with the second direction, one end of the car stop 200 is connected to the rear beam 100, and the other end of the car stop 200 is a free end, the second direction is perpendicular to the first direction, and the first direction and the second direction are both perpendicular to the vertical direction; the bracket trolley maintenance platform 300 is arranged at the end of the car stop 200 away from the sea side, and the bracket trolley maintenance platform 300 is connected to the rear beam 100, and the length direction of the bracket trolley maintenance platform 300 is consistent with the second direction; the anti-hooking round pipe 400 is consistent with the second direction; The hooking circular tube 400 includes a first circular tube segment 410, one end of the first circular tube segment 410 is connected to the bracket trolley maintenance platform 300 and away from the rear beam 100, and the other end of the first circular tube segment 410 is connected to the free end of the car stopper 200; the main trolley 500 is slidingly connected to the rear beam 100, and the car stopper 200 is located between the bracket trolley maintenance platform 300 and the main trolley 500, and the length direction of the lifting wire rope 501 on the main trolley 500 is consistent with the first direction, and the lifting wire rope 501 is located above the anti-hooking circular tube 400.
[0042] In this embodiment, since the distance that the car stopper 200 extends in the second direction is less than the distance between the lifting wire rope 501 and the rear beam 100, the angle a between the end of the first round tube section 410 of the anti-hooking round tube 400 connected to the bracket trolley maintenance platform 300 and the bracket trolley maintenance platform 300 can be 60°-75° (reference Figure 1 ) to ensure that the first circular tube section 410 is located below the lifting wire rope 501. Of course, in other embodiments, the angle between the end of the first circular tube section 410 connected to the bracket trolley maintenance platform 300 and the bracket trolley maintenance platform 300 can be set according to the distance that the car stopper 200 extends along the second direction, which is not limited here. Therefore, by setting the anti-hooking circular tube 400 between the bracket trolley maintenance platform 300 and the car stopper 200, when the main trolley 500 moves and causes the lifting wire rope 501 to shake left and right and bounce up and down, the anti-hooking circular tube 400 can block the lifting wire rope 501 to prevent the lifting wire rope 501 from further hooking under the car stopper 200, thereby effectively improving safety.
[0043] like Figure 1As shown, in some other embodiments of the present invention, the anti-hooking circular tube 400 further includes: a second circular tube segment 420, the second circular tube segment 420 is arranged on the side of the vehicle stopper 200 away from the bracket trolley maintenance platform 300, one end of the second circular tube segment 420 is connected to the rear beam 100, and the other end of the second circular tube segment 420 is connected to the free end of the vehicle stopper 200. In addition, one end of the first circular tube segment 410 away from the bracket trolley maintenance platform 300 and one end of the second circular tube segment 420 away from the rear beam 100 are connected through an arc circular tube segment 430, the first circular tube segment 410 and the second circular tube segment 420 are tangent to the arc circular tube segment 430 respectively, and the arc circular tube segment 430 is connected to the outside of the free end of the vehicle stopper 200 and its arc mouth faces the free end of the vehicle stopper 200.
[0044] In this embodiment, the angle b between the end of the second circular tube section 420 connected to the rear beam 100 and the rear beam 100 is 60°-75° (refer to Figure 1 ), and the arcuate circular tube segment 430 is closely attached to the outer side of the free end of the vehicle stopper 200. Of course, in other embodiments, the angle between the end of the second circular tube segment 420 connected to the rear beam 100 and the rear beam 100 can be set according to the distance that the vehicle stopper 200 extends along the second direction, which is not limited here. Therefore, by surrounding the outer side of the vehicle stopper 200 with the first circular tube segment 410, the arcuate circular tube segment 430 and the second circular tube segment 420, the lifting steel wire rope 501 can be fully blocked when the main trolley 500 moves so that the lifting steel wire rope 501 shakes left and right and bounces up and down, and the lifting steel wire rope 501 is prevented from hooking under the vehicle stopper 200, which effectively improves safety, and the arcuate circular tube segment 430 and the second circular tube segment 420 also improve the structural strength of the anti-hooking circular tube 400.
[0045] like Figure 2 and Figure 3 As shown, in some other embodiments of the present invention, a limiter is provided on the car stopper 200, and the length direction of the limiter is consistent with the first direction; the main trolley 500 is provided with a buffer 510, and the buffer 510 and the limiter are arranged relative to each other along the first direction. The buffer stroke of the buffer 510 of some main trolleys 500 is relatively long. After the buffer 510 of the main trolley 500 contacts the car stopper 200, the main trolley 500 body will continue to move backwards, and the distance between the main trolley 500 and the car stopper 200 will be very narrow. Therefore, if the second circular tube segment 420 is provided, the main trolley 500 will collide with the second circular tube segment 420, causing damage to the second circular tube segment 420 or the main trolley 500. Therefore, when the buffer stroke of the buffer 510 of the main trolley 500 is long, the second circular tube segment 420 can be eliminated or the second circular tube segment 420 can be kept as close as possible to the end surface of the vehicle stop 200 facing the main trolley 500, thereby avoiding collision between the main trolley 500 and the second circular tube segment 420.
[0046] In one embodiment of the present invention, the first circular tube segment 410, the second circular tube segment 420 and the arc-shaped circular tube segment 430 are integrally formed. The integrally formed circular tube has good mechanical properties, good shock resistance and durability, thereby effectively improving the service life of the anti-hooking circular tube 400.
[0047] like Figure 4 As shown, the crane also includes: a car stop protection circular tube 600, which is arranged below the rear beam 100 and the car stop 200 respectively and is bent downward, one end of the car stop protection circular tube 600 is connected to the free end of the car stop 200, and the other end of the car stop protection circular tube 600 is connected to the rear beam 100.
[0048] Specifically, since two lifting steel wires 501 are arranged on the main trolley 500, when the angle a between the end of the first round tube section 410 of the anti-hooking round tube 400 connected to the trolley maintenance platform 300 and the trolley maintenance platform 300 is too large, that is, when the end of the first round tube section 410 of the anti-hooking round tube 400 connected to the trolley maintenance platform 300 is too close to the rear beam 100, the first round tube section 410 cannot be located under the two lifting steel wires 501 at the same time. Therefore, by arranging the car stop protection round tube 600 under the car stop 200, when the outer lifting steel wire 501 shakes left and right and bounces up and down, the car stop protection round tube 600 with a circular arc can block the lifting steel wire 501, and prevent the lifting steel wire 501 from hooking under the car stop 200, thereby effectively improving safety.
[0049] like Figure 4 As shown, the car block protection round tube 600 includes: a car block protection straight tube 610 and a car block protection curved tube 620. One end of the car block protection straight tube 610 is connected to the free end of the car block 200, one end of the car block protection curved tube 620 is connected to the lower end surface of the rear beam 100, and the other end of the car block protection curved tube 620 is connected to one end of the car block protection straight tube 610 away from the free end of the car block 200.
[0050] In this embodiment, the angle c at one end of the car block protection straight tube 610 connected to the free end of the car block 200 can be 30°-45°, and the car block protection curved tube 620 has an arc, so that the car block protection circular tube 600 can block the lifting wire rope 501 toward the side away from the car block 200, preventing the lifting wire rope 501 from hooking under the car block 200, thereby effectively improving safety.
[0051] In one embodiment of the present invention, the vehicle guard protection straight pipe 610 and the vehicle guard protection curved pipe 620 are integrally formed. The integrally formed round pipe has good mechanical properties, good shock resistance and durability. Thus, the service life of the vehicle guard protection round pipe 600 can be effectively improved.
[0052] like Figure 4As shown, the car block protection round tube 600 further includes: a support tube 630, the length direction of the support tube 630 is consistent with the vertical direction, the upper end of the support tube 630 is connected to the car block 200 or the rear beam 100, and the lower end of the support tube 630 is connected to one end of the free end of the car block protection straight tube 610 away from the car block 200. By providing the support tube 630 to support the car block protection straight tube 610 and the car block protection curved tube 620 respectively, deformation of the car block protection straight tube 610 and the car block protection curved tube 620 is avoided, and the service life of the car block protection round tube 600 is effectively improved.
[0053] like Figure 4 As shown, a reinforcing block 101 is provided in the rear beam 100, and one end of the vehicle barrier protection curved pipe 620 connected to the lower end surface of the rear beam 100 is located below the corresponding reinforcing block 101. By providing the reinforcing block 101 in the rear beam 100, the structural strength of the vehicle barrier protection circular pipe 600 can be improved, and the anti-deformation ability of the vehicle barrier protection circular pipe 600 can be further improved.
[0054] like Figure 1 and Figure 2 As shown, the cross section of the vehicle stopper 200 perpendicular to the first direction is a trapezoid. The trapezoidal structural member has high structural strength, which can avoid deformation during contact with the main trolley 500 and improve the service life of the vehicle stopper 200.
[0055] In summary, the crane of the present invention sets an anti-hooking circular tube 400 between the bracket trolley maintenance platform 300 and the car stopper 200. The lifting wire rope 501 above the anti-hooking circular tube 400 will be blocked by the anti-hooking circular tube 400 when it shakes left and right and bounces up and down, and will not be hooked under the car stopper 200, thereby effectively improving safety.
