[0038] The moving assembly 2 includes a driving wheel 21 and a driven wheel 22 which are arranged on the lower support frame 1 and are installed symmetrically on both sides, and are used to drive the lower support frame 1 to move linearly;
[0039] The plowing mechanism 3 includes a plowing claw 31 disposed at one end of the lower support frame 1 for scratching the soil surface advancing on the lower support frame 1, and a lifting component disposed at the inner curved portion of the plowing claw 31 for feeding and outputting the soil accumulated on the upper portion of the plowing claw 31;
[0040] A laying component 4 is arranged at the other end of the lower support frame 1 and is used to lay the cable along the channel opened by the plowing mechanism 3;
[0041] The lifting assembly 5 is provided through the lower support frame 1 and is fixedly connected to the connecting ends between the plowing mechanism 3 and the laying assembly 4, so as to drive the plowing mechanism 3 and the laying assembly 4 to move in the vertical direction.
[0042] In a specific implementation, by installing a moving assembly 2 on a lower support frame 1 welded by a support column at the lower part of the upper support frame 100, and respectively installing a plowing mechanism 3 and a laying assembly 4 at the head end and the tail end of the lower support frame 1, the plowing claw 31 included in the plowing mechanism 3 can be used to cut the advancing soil during the straight-line movement of the device, and the cable can be laid underground along the channel cut by the plowing mechanism 3 through the laying assembly 4, so that the excavation and laying are synchronized, and the whole process will not cause any damage to the surrounding area, and the operation is simple;
[0043] The lifting assembly 5 is also provided to vertically adjust the depth of excavation and laying, thereby avoiding uneven ground surfaces and reducing the risk of cable damage due to external forces.
[0044] It should be noted that one end of the driving wheel 21 included in the mobile component 2 is installed and connected to a driving motor (not shown in the figure), and a belt transmission structure for transmission (not shown in the figure) is installed between the driving wheel 21 and the driven wheel 22. Under the drive of the driving motor, the driving wheel 21 and the driven wheel 22 included in the mobile component 2 can be synchronously operated, and the lower support frame 1 and the related structures installed on the lower support frame 1 can be driven to move linearly along the ground, thereby realizing the subsequent laying function of the equipment.
[0045] It should be noted that the plowing claw 31 is designed to be an inclined "V" structure, which is convenient for plowing and excavating in the soil layer through the "V" structure.
[0046] It should be noted that the model of the cable conveyor 200 used in this equipment is DCS-5.
[0047] In one embodiment, the lifting assembly includes a feeding cylinder 32 vertically disposed on the plowing claw 31 and having a feeding port 321, and a spiral conveying unit 33 disposed in the feeding cylinder 32;
[0048] The spiral conveying unit 33 includes a central axis 332 vertically arranged in the feeding cylinder 32, and a spiral conveying blade 331 arranged outside the central axis 332. With this design, through the vertically distributed feeding cylinder 32 welded at the rear end of the inner curved part of the plowing claw 31, and the feed port 321 left by turning at the lower part of the feeding cylinder 32, when the plowing claw 31 cuts the soil layer forward, the soil accumulated on the inner curved part of the plowing claw 31 will be lifted and transported upward under the rotation of the spiral conveying unit 33 welded by the spiral conveying blade 331 and the central axis 332, so as to reduce the accumulation of soil and avoid the soil accumulated on the plowing claw 31 affecting the excavation efficiency of the plowing claw 31, and the construction effect is good.
[0049] In one embodiment, a guide plate 34 is provided on the material delivery cylinder 32, and two connected inclined surfaces 341 with a lower outer surface and a higher inner surface are provided on the guide plate 34, and a discharge pipe 322 connected to the material delivery cylinder 32 is provided at the upper part of the joint between the two inclined surfaces 341;
[0050] The discharge pipe 322 is used to discharge the soil lifted upward. With this design, through the guide plate 34 sleeved on the upper end of the outer part of the delivery barrel 32, and the two butted and lower outer and higher inner inclined surfaces 341 symmetrically turned on the upper surface of the guide plate 34, when the discharge pipe 322 connected to the upper end of the delivery barrel 32 is welded to discharge the soil, it will directly fall on the inclined surface 341. At this time, the lower outer and higher inner structure on the inclined surface 341 can, under the dead weight of the soil, be inclined along the inclined surface 341 to respectively guide the soil to the two sides of the excavated channel, which not only solves the problem of excavated soil accumulation, but also keeps the soil in the excavated channel separated on both sides, which is convenient for the subsequent cable burying operation.
[0051] In one embodiment, the driven walking wheel 22 is provided with a worm segment 221, and the worm segment 221 is provided with a transmission assembly 6 which is transmission-connected to the central shaft 332;
[0052] The transmission assembly 6 includes a worm wheel 66 meshingly arranged at the side of the worm segment 221, a transmission shaft 65 arranged on the worm wheel 66, a second belt pulley 64 is arranged on the transmission shaft 65, and the second belt pulley 64 is horizontally arranged with a first belt pulley 62 sleeved on the central shaft 332 through a transmission belt 63, and a fixed sleeve 61 is arranged on the first belt pulley 62;
[0053] The central shaft 332 is provided with a slot, and the fixed sleeve 61 is provided with a protrusion adapted to the slot. In this design, a worm section 221 is machined on the shaft of the driven walking wheel 22, and the worm wheel 66 is meshed and connected to the side of the worm section 221. When the driven walking wheel 22 rotates forward to drive the device, the generated force will be transmitted to the transmission shaft 65 sleeved at the center of the end face of the worm wheel 66 through the worm and worm gear transmission structure formed by the worm section 221 and the worm wheel 66, and then the second pulley 64 sleeved at the upper end of the transmission shaft 65 will rotate accordingly, and the rotational force will be transmitted to the first pulley 62 through the transmission belt 63 wound around the second pulley 64, driving the fixed sleeve 61 sleeved at the center of the end face of the first pulley 62 to rotate, thereby realizing the transmission of force. During the forward movement of the device, the feeding soil is continuously lifted upward through the central shaft 332 and the spiral conveying blade 331 of the central combination of the fixed sleeve 61, and the use effect is good.
[0054] It should be noted that the vertical movement of the fixed sleeve 61 and the central shaft 332 is limited by the sliding movement of the grooves and the protrusions.
[0055] In one embodiment, the laying assembly 4 includes a push plate 41 for flattening the soil, which is arranged at the other end of the lower support frame 1 and is arranged at the same height on the lower horizontal surface of the plowing claw 31, and an upper conveying frame 42 arranged on the push plate 41. A lower conveying frame 43 fixed to the side of the push plate 41 is arranged on the outer side of the upper conveying frame 42, and an arc conveying trough 44 for conveying cables is arranged in communication between the upper conveying frame 42 and the lower conveying frame 43. With this design, by installing the push plate 41 at the other end of the lower support frame 1 and at the same height as the lower horizontal surface of the plowing claw 31, the front structure of the push plate 41 can be used to flatten the soil scattered in the excavated channel, so that the bottom surface of the excavated channel is in one plane, which is convenient for laying cables horizontally;
[0056] By means of an upper conveying frame 42 welded on the push plate 41 and a lower conveying frame 43 welded to the outside of the upper conveying frame 42 and to the side of the push plate 41, and a curved conveying groove 44 for cable conveying which is machined and connected on the upper conveying frame 42 and the lower conveying frame 43, the cables on the cable drum can be conveyed to the excavated channel along the straight path of the equipment.
[0057] It should be noted that guide rollers for smooth cable transportation are horizontally installed in the arc conveying trough 44, and there are multiple guide rollers installed in the arc conveying trough 44 with the same spacing, which can be used to simultaneously convey and lay one or more cables.
[0058] In one embodiment, the lifting assembly 5 includes a first hydraulic cylinder 51 disposed on the bottom surface of the upper support frame 100 and penetrating the lower support frame 1, and a connecting cross frame 52 disposed at the bottom end of the first hydraulic cylinder 51 for connecting the plowing mechanism 3 and the laying assembly 4. In this design, the first hydraulic cylinder 51 is bolted to the bottom surface of the upper support frame 100, and the connecting cross frame 52 is bolted and connected to the bottom end of the telescopic part of the first hydraulic cylinder 51, wherein the two ends of the connecting cross frame 52 are respectively welded and fixedly connected to the guide plate 34 included on the plowing mechanism 3 and the inner vertical surface of the upper conveying frame 42 included on the laying assembly 4, so that the plowing mechanism 3 and the laying assembly 4 can be adjusted in height under the lifting of the first hydraulic cylinder 51, so as to meet the requirements of excavation and burial of cables at various depths.
[0059] In one embodiment, the first hydraulic cylinder 51 is provided with a second hydraulic cylinder 53 fixed to the side of the lower support frame 1 through an oil pipeline, and the bottom end of the second hydraulic cylinder 53 is provided with an outer support frame 7 for making the driving wheel 21 and the driven wheel 22 leave the ground. With this design, the oil discharged from the return oil chamber on the first hydraulic cylinder 51 is sent to the oil inlet chamber of the second hydraulic cylinder 53 through the oil pipeline. When the two hydraulic cylinders are connected in series, once the effective areas of the pistons of the series oil chambers are the same, synchronous movement can be achieved, so that the outer support frame 7 bolted at the bottom end of the second hydraulic cylinder 53 and the plowing mechanism 3 and laying assembly 4 connected to the connecting cross frame 52 bolted at the bottom end of the first hydraulic cylinder 51 can make synchronous opposite movements, so that the equipment can switch between moving or parking states in the operations of laying cables underground and laying cables on the ground.
[0060] It should be noted that the synchronization accuracy of the series hydraulic cylinders will be reduced due to factors such as manufacturing errors, friction resistance and oil leakage. In order to compensate for these errors, compensation devices can be set in the circuit, such as a three-position four-way electromagnetic reversing valve, a hydraulically controlled one-way valve and two travel switches.
[0061] Preferably, the outer support frame 7 is slidably connected to the plowing mechanism 3 and the laying assembly 4. The corresponding connection positions on the outer support frame 7 and the plowing mechanism 3 and the laying assembly 4 are slidably mounted in the form of slide grooves and slide rails.
[0062] In one embodiment, a covering groove 71 for the driving wheel 21 and the driven wheel 22 to vertically pass through is correspondingly provided on the inner side of the outer support frame 7. With this design, the driving wheel 21 and the driven wheel 22 can be completely covered when the device is parked, by turning the covering groove 71 on the inner side of the outer support frame 7 to cooperate with the driving wheel 21 and the driven wheel 22, so as to avoid displacement during parking and maintain parking stability.
[0063] In one embodiment, two symmetrical covers 201 are arranged at intervals on the cable conveyor 200, and a conveyor belt 2011 for conveying cables is correspondingly arranged in the covers 201, and upper and lower guide wheel groups 202 for limiting the direction of the cables are respectively arranged at both ends of the upper support frame 100. With such a design, the cable conveyor 200 installed on the upper support frame 100 can be arranged at a construction site, about 15-30 meters away from the cable drum, and the cable conveyor 200 is started, and the rotation of the conveyor belt 2011 will carry out the horizontal conveying and laying of cables under the support of the upper and lower guide wheel groups 202 at both ends.
[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
