Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of cranes, and in particular to a suspended anti-entanglement wire rope retainer. Background Art
[0002] Compared with mast-type rotary cranes, the luffing mechanism and lifting mechanism of traditional full-rotating cranes are usually installed on the turntable of the crane, which has disadvantages such as large rotation radius, heavy weight, and high cost. Mast-type rotary cranes install the luffing mechanism and lifting mechanism on a fixed base at the bottom of the crane mast structure, and the boom rotates with the support plate at the hinge point below it. The turntable is eliminated, which greatly reduces the tail size of the crane and significantly reduces the weight and cost of the crane. However, this type of crane has the problems of limited rotation angle and interference friction of the mechanism wire rope. That is, when the crane boom rotates more than 180 degrees in one direction, the luffing and lifting wire ropes are easily entangled and rubbed against each other due to the rotation of the guide pulley group at the top of the mast relative to the fixed mechanism at the bottom of the mast, which causes the wire rope to wear and affects the safe use of the crane.

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.
[0039] The present disclosure provides a suspended anti-winding wire rope retainer. Figures 1 to 5 The retaining frame includes a suspension device 1, a split retaining frame 2 and a guide wheel device 3. The suspension device 1 is used to install the split retaining frame 2; the split retaining frame 2 is used to perform a primary constraint on the wire rope assembly; the guide wheel device 3 is used to perform a secondary constraint on the wire rope assembly to separate each wire rope.
[0040] In the disclosed embodiment, the retaining frame is composed of a suspension device 1, a split retaining frame 2 and a guide wheel device 3. The split retaining frame 2 is installed on the crane through the suspension device 1. The split retaining frame 2 is arranged at a position where the steel wire ropes are likely to interfere with each other. The steel wire ropes are constrained once by the split retaining frame 2 to limit the position of each steel wire rope. The steel wire ropes are constrained twice by the guide wheel device 3 to separate each steel wire rope so that a certain distance is maintained between each steel wire rope to avoid entanglement between the steel wire ropes due to interference and to avoid friction and wear of the steel wire ropes.
[0041] In the disclosed embodiment, during the rotation of multiple steel wire ropes, the position where interference occurs will change according to the distance between the steel wire ropes at both ends. Thus, the component force generated by this change enables the retaining frame to adapt to the possible interference position up and down, so that the steel wire ropes always maintain a certain distance during use, thereby avoiding interference and entanglement of the steel wire ropes, preventing the steel wire ropes from being worn, and improving the safety of crane use.
[0042] In one embodiment of the present disclosure, see Figures 1 to 5A plurality of guide wheel devices 3 are arranged at intervals on one side wall of the split cage 2, and the guide wheel device 3 is rotatably connected to the split cage 2. In this way, the steel wire rope running during the lifting process can be restrained, and the wear of the steel wire rope during the restraint process can be reduced.
[0043] Alternatively, see Figures 1 to 5 A plurality of suspension devices 1 are arranged at intervals at the top of the split cage 2, and the suspension devices 1 are detachably connected to the split cage 2. In this way, the split cage 2 can be quickly installed on the crane, and the suspension devices 1 can be easily replaced.
[0044] In one embodiment of the present disclosure, see Figures 1 to 5 There are two split cages 2, and the two split cages 2 and the suspension device 1 and the guide wheel device 3 thereon are symmetrically arranged, and the two split cages 2 are detachably connected by a pin shaft 21; the wire rope assembly is located between the two split cages 2. In this way, the wire rope assembly can be constrained in the two split cages 2, and each wire rope can be constrained once; the two split cages 2 connected by the pin shaft 21 are easy to disassemble and assemble, and it is convenient to inspect and repair the split cages 2 and the internal structure thereof.
[0045] In one example, the pins 21 at both ends of the split retainer 2 can be removed simultaneously, so that the two split retainers 2 can be completely separated, and the split retainer 2 and the internal structure thereof can be inspected and repaired.
[0046] In another example, only the pin 21 at one end of the split retainer 2 may be disassembled so that the two split retainers 2 can be opened and closed, thereby realizing the inspection and maintenance of the split retainer 2 and the structure inside it.
[0047] In one embodiment of the present disclosure, see Figures 1 to 5 One of the two split retainers 2 is provided with a single-layer connection seat 22, and the other of the two split retainers 2 is provided with a double-layer connection seat 22, and the connection seat 22 is located on a side wall of the two split retainers 2 close to each other; a through hole 23 is opened on the connection seat 22, and two adjacent connection seats 22 are detachably connected through a pin shaft 21. In this way, the two split retainers 2 can be quickly assembled, and the two split retainers 2 are convenient to disassemble and assemble.
[0048] Optionally, when two split retaining frames 2 are connected, the single-layer connecting seat 22 is inserted into the double-layer connecting seat 22 so that the through hole 23 on the single-layer connecting seat 22 is aligned with the through hole 23 on the double-layer connecting seat 22, and the single-layer connecting seat 22 and the double-layer connecting seat 22 are connected by the pin shaft 21 to achieve the assembly of the two split retaining frames 2.
[0049] Optionally, connecting seats 22 are respectively provided at both ends of the split retainer 2 , that is, two connecting seats 22 are provided on any split retainer 2 , and the two split retainers 2 are detachably connected via two pin shafts 21 .
[0050] In one example, the two connection seats 22 on one of the two split retainers 2 are both single-layer connection seats 22, and the two connection seats 22 on the other of the two split retainers 2 are both double-layer connection seats 22. In this way, the two split retainers 2 are connected in parallel, and the two split retainers 2 are easy to disassemble and assemble.
[0051] In another example, one of the two connection seats 22 on any split retainer 2 is a single-layer connection seat 22, and the other is a double-layer connection seat 22. In this way, the two split retainers 2 are connected in a cross-type manner, and the forces on the two split retainers 2 during use are more balanced, and the connection seats 22 are not easily damaged.

In this way, the two split retainers 2 can be kept balanced during use, the restraining force of the split retainer 2 and the guide wheel device 3 on the wire rope assembly is improved, and the entanglement between the wire ropes is avoided.
[0053] In one example, there are four groups of suspension devices 1, which are installed on two split retaining frames 2, that is, two groups of suspension devices 1 are installed on any split retaining frame 2, and the two groups of suspension devices 1 on any split retaining frame 2 are symmetrically arranged at both ends of the split retaining frame 2.
[0054] In one embodiment of the present disclosure, see Figures 1 to 5 The top of the split retainer 2 is provided with a lifting lug 24 corresponding to the suspension device 1, and the suspension device 1 is detachably connected to the split retainer 2 through the lifting lug 24. In this way, the suspension device 1 and the split retainer 2 can be firmly connected, and the suspension device 1 and the split retainer 2 can be prevented from being separated, thereby improving the effect of separating each wire rope.
[0055] In an example, the number of the lifting ears 24 is 4, and the lifting ears 24 correspond to the suspension devices 1 one by one.
[0056] In one embodiment of the present disclosure, see Figures 1 to 5The guide wheel device 3 is located between the two split retainers 2. The guide wheel device 3 on any split retainer 2 is symmetrically arranged up and down, and the guide wheel device 3 is in a vertical state; the wire rope assembly is located between two adjacent guide wheel devices 3. In this way, the wire rope assembly can be constrained in two adjacent guide wheel devices 3 in a vertical state, and the secondary constraint of each wire rope is achieved, thereby improving the constraint force of the guide wheel device 3 on the wire rope assembly.
[0057] In one embodiment of the present disclosure, see Figures 1 to 5 The wire rope assembly includes a left hoisting wire rope 4, a luffing wire rope 5, and a right hoisting wire rope 6.

The left hoisting wire rope 4, the luffing wire rope 5, and the right hoisting wire rope 6 are respectively located between two adjacent guide wheel devices 3. In this way, the wire rope assembly can be separated, so that the wire ropes always maintain a certain distance during operation, and the entanglement between the wire ropes can be prevented.
[0058] Optionally, the wire rope assembly includes a left lifting wire rope 4, a right lifting wire rope 6 and at least one variable-length wire rope 5 located between the left lifting wire rope 4 and the right lifting wire rope 6, and the left lifting wire rope 4, the right lifting wire rope 6 and at least one variable-length wire rope 5 are respectively located between two adjacent guide wheel devices 3.
[0059] Optionally, the number of guide wheel devices 3 on any split retaining frame 2 is twice the number of steel wire ropes in the wire rope assembly, and the guide wheel devices 3 are symmetrically arranged up and down, that is, two guide wheel devices 3 located on the same axis correspondingly constrain one steel wire rope, thereby improving the restraining force of the guide wheel device 3 on the steel wire rope.
[0060] In one embodiment of the present disclosure, see Figure 6 The split retainer 2 includes a base plate 25, a mounting plate 26, a connecting plate 27, and a rib plate 28. The base plate 25 is provided with a mounting plate 26 at one end, and a connecting plate 27 at the other end. The guide wheel device 3 is provided on the mounting plate 26. The base plate 25 is located in the middle of the mounting plate 26 and the connecting plate 27. The mounting plate 26 and the connecting plate 27 are connected by a plurality of rib plates 28 arranged at intervals.
