Description

Technical Field

[0001] The utility model relates to the technical field of bridge cranes, in particular to an anti-knotting mechanism and a crane. Background Art

[0002] A bridge crane is a type of lifting equipment that is horizontally mounted above workshops, warehouses and material yards to lift materials. Because its two ends are located on tall concrete columns or metal supports, its shape is like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides. The space under the bridge can be fully utilized to lift materials without being hindered by ground equipment. It is the most widely used and largest number of lifting machinery.

[0003] Traditional bridge cranes on the current market have some defects when in use. For example, the limit structure of the load-bearing rope inside the overhead crane is not stable enough when in use, which makes it easy to get tangled, affecting the efficiency of use. For this reason, we propose an anti-knot mechanism and an overhead crane. Utility Model Content

[0038] Example 1

[0039] Reference Figure 1 , which is the first embodiment of the utility model, and provides an anti-knotting mechanism and an overhead travelling crane, comprising: a protective housing 100, and a wire management assembly 200 and an adjustment assembly 300 disposed in the protective housing 100, wherein the wire management assembly 200 is located on the adjustment assembly 300;

[0040] The protective shell 100 is provided with a wire inlet 101 and a wire outlet 102; the wire inlet 101a is arranged at the top of the overhead travelling vehicle body 101, and the load-bearing rope is separated inside the protective shell 100 to prevent the load-bearing rope from getting tangled inside the protective shell 100 when being stored.

[0041] Among them, the adjustment component 300 includes a first adjustment component 301, a second adjustment component 302 and a first tensioning component 303. The two ends of the first tensioning component 303 are respectively connected to the first adjustment component 301 and the second adjustment component 302. The first adjustment component 301 and the second adjustment component 302 are fixed inside 100 and are located between the support plates 202. The support column 301a is used to support the adjustment component 300 to adjust the load-bearing rope.

[0042] The cable management assembly 200 includes a second limiting wheel 201 and a support plate 202. The two ends of the support plate 202 are respectively connected to the second limiting wheel 201 and the inner wall of the protective shell 100. The support plate 202 is fixed inside the protective shell 100. The support plate 202 is used to support the second limiting wheel 201, so that the second limiting wheel 201 can separate the load-bearing ropes on both sides.

[0043] Usage process: First, input the load-bearing rope into the protective shell 100 through the wire inlet 101. During the process of retracting the load-bearing rope, the load-bearing rope is staggered on the wire management component 200, and then the load-bearing rope is driven to deflect through the adjustment component 300, so that the load-bearing rope is in a taut state, thereby increasing the tension of the load-bearing rope and preventing knotting.

[0044] Example 2

[0045] Reference Figures 1 to 4 , which is the second embodiment of the utility model, and is different from the previous embodiment in that it further comprises: the first adjustment member 301 and the second adjustment member 302 have the same structure;

[0046] The first adjustment member 301 includes a support column 301a and a first elastic member 301b wound around the outside of the support column 301a; the first elastic member 301b is a pressure spring, and the tension of the load-bearing rope is adjusted through the elastic force of the first elastic member 301b.

[0047] The two ends of the support column 301 a are respectively fixed to the two inner walls of the protective housing 100 .

[0048] The first tensioning member 303 includes a first limiting wheel 303a and a first limiting block 303b and a second limiting block 303c arranged at two ends of the first limiting wheel 303a;

[0049] Among them, the first limit block 303b and the second limit block 303c are respectively mounted on the support column 301a of the first adjustment member 301 and the second adjustment member 302, and the first limit block 303b and the second limit block 303c slide on 301a, thereby driving the first limit block 303b and the second limit block 303c to adjust the load-bearing rope through 301b.

[0050] The line inlet 101, the second limiting wheel 201, the first limiting wheel 303a and the line outlet 102 are arranged in a staggered manner.

[0051] Usage process: When the load-bearing rope is wound up, the elastic force exerted on the first limit block 303b and the second limit block 303c by the multiple first elastic members 301b sleeved on the outside of the adjustment component 300 causes the first limit block 303b and the second limit block 303c to move toward each other, and the first limit block 303b and the second limit block 303c then drive the first limit wheels 303a on both sides to move toward each other, and the first limit wheel 303a drives the load-bearing rope to move toward each other until the load-bearing rope is in a taut state, thereby increasing the tension of the load-bearing rope and preventing the load-bearing rope from tangling to a large extent.

[0057] The connecting member 402 is respectively disposed on the first limiting block 303b and the second limiting block 303c.

[0058] The locking assembly 500 includes a receiving column 501 arranged in the protective shell 100, and a second elastic member 501a is sleeved on the outside of the receiving column 501. A first locking plate 501b and a second locking plate 501b-1 are sleeved on the outside of the receiving column 501 and located between the second elastic member 501a.

[0060] Arc grooves are respectively arranged between the first locking plate 501b and the second locking plate 501b-1. The arc grooves arranged between the first locking plate 501b and the second locking plate 501b-1 are used to position the load-bearing rope.

[0061] Usage process: when the load-bearing rope is working, the motor is driven to rotate the output rod 401 through the motor, the output rod 401 drives the first reset link 401a and the second reset link 401b on both sides to rotate, the second reset link 401b drives the connecting member 402 to move to both sides, the connecting member 402 drives the first limit block 303b and the second limit block 303c to move to both sides, at this time, the first limit block 303b and the second limit block 303c drive the first rotating plate 601a and the second rotating plate 601b on the moving plate 601 to move up, and the first rotating plate 601a and the second rotating plate 601b on the moving plate 601 are rotated.
