[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0028] Please refer to the following Figures 1 to 6 The cable arrangement structure of a comprehensive excavation machine according to an embodiment of the utility model is described.
[0029] like Figure 1 and Figure 2As shown, the cable arrangement structure of the multi-purpose excavator according to the embodiment of the utility model includes: a belt conveyor 1, a multi-purpose excavator 2, a cable basket 3, a cable 4 and a cable clamp 5. The belt conveyor 1 extends along a first direction, the excavator 2 is arranged on one side of the belt conveyor 1 along the first direction, the cable basket 3 is arranged on the other side of the belt conveyor 1 along the first direction, the cable 4 includes a winding section 45 and a drag section 46, the winding section 45 is arranged in the cable 4 frame, and the drag section 46 is arranged on one side of the belt conveyor 1 along the width direction of the belt conveyor 1, and the width direction of the belt conveyor 1 is orthogonal to the first direction, one end of the drag section 46 is connected to the winding section 45, and the other end of the drag section 46 is connected to the excavator 2, the cable clamp 5 includes a plurality of chain links 51, each of which is provided with a cavity 513, and the plurality of chain links 51 are movably connected in sequence along a preset direction (i.e., the extension direction of the drag section 46) to connect the cavity 513 in series and form a protective cavity 52, and the drag section 46 is penetrated through the protective cavity 52.
[0030] According to the cable arrangement structure of the excavator according to the embodiment of the utility model, by arranging the reeling section 45 in the cable basket 3, the cables 4 that do not need to be towed can be collected to reduce the probability of damage caused by long-term exposure of the reeling section 45 to the outside world; because the towing section 46 is inserted into the protective cavity 52, the towing section 46 can be protected by the cable clamp 5 to avoid the problem of damage caused by long-term contact with the ground of the towing section 46, and the multiple chain links 51 are movably connected in sequence along the preset direction, so that the cable clamp 5 has a certain flexibility, so as not to interfere with the movement of the towing section 46. On the other hand, when the cable clamp 5 is damaged, the operator can replace and maintain the cable clamp 5 on the ground, so the cable arrangement structure of the excavator according to the embodiment of the utility model can reduce the wear of the cable 4, extend the service life of the cable 4, and reduce the cost of later maintenance.
[0031] It can be understood that the belt conveyor 1 is used to transport the coal mined by the comprehensive excavation machine 2, and the first direction is the direction of transmission of the belt conveyor 1, that is, Figure 1 The front-to-back direction.
[0032] In some embodiments, Figure 1 As shown, the cable arrangement structure of the comprehensive excavator also includes a receiving groove 6, and the receiving groove 6 is arranged along the width direction of the belt conveyor 1 (such as Figure 1 The cable clamp 5 is arranged on one side of the belt conveyor 1, and at least part of the cable clamp 5 is arranged in the receiving groove 6. The cable arrangement structure of the excavator of the utility model can avoid the problem of construction workers stepping on the cable clamp 5 by arranging the cable clamp 5 in the receiving groove 6, thereby preventing damage to the cable 4 in the cable clamp 5, which is conducive to extending the service life of the cable 4.
[0033] For example, the storage slot 6 can be opened on the ground. For another example, a protective plate is provided on one side of the width direction of the belt conveyor 1, and the storage slot 6 is opened on the protective plate. The present application does not limit the specific position of the storage slot 6, and it only needs to be able to store and hide the cable clamp 5.
[0034] Optionally, the chain link 51 is an insulating plastic part. It is understandable that in order to reduce the probability of leakage due to damage to the cable 4 skin, the chain link 51 can be set as an insulating plastic part to avoid conducting the current on the cable 4 to the cable clamp 5, thereby further ensuring the personal safety of construction workers, facilitating processing and manufacturing, and having a low production cost.
[0035] In some embodiments, Figures 3 to 5 As shown, the link 51 includes two ear plates 511 and two baffles 512, the two ear plates 511 are arranged at intervals along the width direction of the cable clamp 5, the ear plates 511 of two adjacent links 51 are pivotally connected, and the two baffles 512 are arranged on both sides of the ear plates 511 along the up-down direction of the cable clamp 5, and the ear plates 511 and the baffles 512 jointly define a cavity 513. It can be understood that the two baffles 512 are arranged in the left-right direction and the two baffles 512 are arranged in the up-down direction, so that the link 51 forms a frame structure, thereby improving the structural strength of the link 51 and improving the compression resistance of the link 51. In addition, since the ear plates 511 of two adjacent links 51 are pivotally connected, the cable clamp 5 can be bent into any shape, and the use effect is better.
[0036] Optionally, at least one baffle 512 is detachably connected to the ear plate 511. It is understandable that when the cable clamp 5 needs to be replaced, the baffles 512 of the plurality of links 51 can be opened so that the operator can separate the cable clamp 5 from the cable 4, thereby facilitating the operator to replace the cable clamp 5 and to check the wear of the cable 4 in the cable clamp 5.
[0037] In one example, if Figures 3 to 5 As shown, one end of the baffle 512 is pivotally connected to one ear plate 511, and the other end of the baffle 512 is engaged with the other ear plate 511. Figure 5 As shown, a pivot 5111 is provided on one ear plate 511, and a baffle plate 512 is pivotally connected to the pivot 5111. A clamping hole 5112 is provided on the other ear plate 511, and the other end of the baffle plate 512 is clamped with the clamping hole 5112 on the other ear plate 511. When the cable clamp 5 needs to be removed from the cable 4, the other end of the baffle plate 512 can be separated from the clamping hole 5112, and the baffle plate 512 and the ear plate 511 will not be separated at this time, so that it is convenient for operators to disassemble and install the cable clamp 5.
[0038] In some embodiments, Figure 6As shown, the cable 4 includes a core 41, a metal layer 43 and a protective sleeve 44, wherein the core 41 is arranged in the metal layer 43, and the metal layer 43 is arranged in the protective sleeve 44. The waterproof layer 42 is composed of a non-absorbent layer and a cross-linked absorbent layer, wherein the non-absorbent layer material is polyurethane with latex added, and the absorbent layer is composed of highly absorbent wood pulp fiber, and the metal layer 43 is a graphite wire reinforced with nickel wire and braided with steel wire. The material of the protective sleeve 44 is polymethyl trifluoropropyl siloxane with oil resistant agent, graphite and silicon carbide added. In this way, the drag resistance and wear resistance of the cable 4 can be improved, and the service life of the cable 4 can be extended.
[0039] Alternatively, if Figure 6 As shown, the cable 4 further includes a waterproof layer 42, which is disposed between the wire core 41 and the metal layer 43. For example, the waterproof layer 42 is a chloroprene rubber material layer, thereby improving the waterproof effect of the cable and extending the service life of the cable.
