Description

Technical Field

[0001] The invention relates to the technical field of cable working equipment, and in particular to a split hydraulic traction machine. Background Art

[0002] Cable operations involve many aspects, mainly including the installation, maintenance and repair of cables. Cable laying is the process of placing cables in designated locations according to design requirements. It involves selecting appropriate cable types, determining laying paths, and installing cables in predetermined locations to ensure efficient and safe transmission of power or signals. Cables can be laid above ground, underground, in walls or other structures, and usually include protecting and fixing cables to prevent damage. A cable laying tractor is a device used for cable laying, mainly used to guide and pull cables during the laying process. It pulls cables from reels or storage devices into predetermined installation paths through traction, and is particularly suitable for long-distance cable laying operations.

[0003] However, when the existing traction machine is in operation, the hydraulic system may not be able to provide sufficient traction force for particularly long or heavy cables. In a single hydraulic traction structure, the traction force may decrease as the length of the cable increases. As the traction distance increases, the oil pressure will decrease, resulting in a decrease in traction force. As the length of the cable increases, friction and resistance will also increase, thereby increasing the load of the system and increasing energy consumption. In addition, the single traction structure equipment is large and bloated, difficult to adjust, and the traction force control is not precise enough. The cable may also be damaged due to excessive tension or uneven traction. Therefore, the present invention proposes a split hydraulic traction machine to solve the problems mentioned in the above background technology. Summary of the invention

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-7 A split hydraulic traction machine comprises a carrier vehicle 1, a traction base 2 is fixedly installed on the upper side of the carrier vehicle 1, a support frame 3 is rotatably connected to the outer side of the traction base 2, a traction frame 4 is rotatably connected to the outer end of the support frame 3, a plurality of wire clamping traction mechanisms 8 are arranged inside the traction frame 4, a hydraulic cylinder 1 5 is arranged between the front end and the support frame 3, a hydraulic cylinder 2 6 is arranged between the rear end and the support frame 3, the lower end of the hydraulic cylinder 1 5 is rotatably connected to the traction base 2, and a slider seat 10 is rotatably connected to the upper end of the hydraulic cylinder 1 5, the slider seat 10 is located on the left and right outer sides of the traction frame 4, and the left and right outer sides of the traction frame 4 are provided with slide grooves corresponding to the slider seat 10, and the upper and lower ends of the hydraulic cylinder 2 6 are rotatably connected to the support frame 3 and the traction base 2 respectively, a winding drum 9 is rotatably connected inside the traction base 2, the cable is wound on the winding drum 9, and a guide roller 15 transferred to the traction base 2 is arranged on the upper front side of the winding drum 9, and the cable is guided through the guide roller 15 to pass through the corresponding wire clamping traction mechanism 8;

[0032] Furthermore, referring to Figure 1-3, by controlling the extension and retraction of the hydraulic cylinder 1 5 alone and controlling the rotation angle of the connected traction frame 4, the traction mechanism maintains an oblique traction form, which is suitable for the initial laying requirements of the cable, and the interfering cable is pulled to a high place. The hydraulic cylinder 1 5 can also be controlled to cooperate with the hydraulic cylinder 2 6, and the hydraulic cylinder 2 6 pushes the support frame 3 connected to the front side, and cooperates with the hydraulic cylinder 1 5 to lift the traction frame 4 and keep it horizontal, which is suitable for the traction and laying of cables at both ends of the same height;

[0033] Furthermore, referring to Figure 7 The wire clamping traction mechanism 8 includes a slide 801, a load-bearing seat 803 sliding inside the slide 801 is arranged on the front side of the slide 801, a movable seat 804 is arranged inside the load-bearing seat 803, hydraulic cylinders 3 802 are arranged between the two ends of the slide 801 surface and the upper side of the movable seat 804, the front and rear ends of the hydraulic cylinders 3 802 are rotatably connected with the movable seat 804 and the slide 801 respectively, the movable seat 804 slides back and forth inside the load-bearing seat 803, and the weight of the load-bearing seat 803 is greater than the weight of the movable seat 804, and the weight-bearing seat 803 is provided with limit blocks 1 808 corresponding to the movable seat 804 on the left and right sides, the movable seat 804 in the front load-bearing seat 803 is pushed by the hydraulic cylinders 3 802 on both sides until the movable seat 804 contacts the limit blocks 1 808 on the left and right sides of the weight-bearing seat 803, so that the external load-bearing seat 803 can be linked and pushed forward together;

[0034] Furthermore, referring to Figure 6 , 7 A translation clamp seat 805 that slides forward and backward is arranged at the lower side of the movable seat 804, and an extrusion spring 806 is arranged between the front end of the translation clamp seat 805 and the rear movable seat 804, a rotating clamp seat 807 that is transferred to the movable seat 804 is arranged at the lower side of the translation clamp seat 805, and a clamping frame 809 is arranged on the left and right sides of the rear side of the rotating clamp seat 807, and a bevel gear 811 is fixed to the left and right outer sides of the transfer part of the rotating clamp seat 807, and a spur gear 812 is fixed to the outer side of the bevel gear 811, and a corresponding meshing spur gear piece 813 is arranged on the upper side of the spur gear 812, and the two spur gear pieces 813 are respectively fixed to the left and right lower sides of the load-bearing seat 803, and the clamping frame 809 is rotatably connected to the movable seat 8 04, a torsion spring is provided at the transition of the clamping frame 809, and a clamping block corresponding to the cable is fixed at the rear end of the clamping frame 809, and a bevel gear 1 810 is fixed at the lower side of the transition part of the clamping frame 809, and the bevel gear 1 810 is meshed with the corresponding bevel gear 2 811 at the lower side. When the movable seat 804 is pushed forward, firstly, a relative displacement occurs between the movable seat 804 and the external load-bearing seat 803, and the movable seat 804 that moves forward, and the spur gears 812 on the left and right sides of the lower side are meshed and transmitted with the spur gear piece 813 on the upper side, so that the rotating clamp seat 807 connected and fixed in the middle rotates upward, and cooperates with the translation clamp seat 805 on the corresponding inclined surface to complete the clamping of the front end of the cable passing through the slot;

[0035] Furthermore, referring to Figure 1 , 5 Similarly, when the spur gears 812 on both sides rotate, the bevel gear 2 811 fixed on the inner side rotates, and the bevel gear 2 811 transmits the bevel gear 1 810 meshing on the upper side, so that the clamping frame 809 connected to the bevel gear 1 810 rotates outward, and the clamping frame 809 rotating outward passes through the rear end clamping frame 809 of the cable, and cross-tightens the rear end of the cable, and then completes the front and rear tightening of the cables while completing the advancement of the movable seat 804 in the clamping wire traction mechanism 8, so as to realize the graded advancement of the cables, and the front side clamping wire traction mechanism 8 completes the same action. The specific process is that after the rear clamping wire traction mechanism 8 completes a push, after the recovery is opened, the front clamping wire traction mechanism 8 completes the second stage of the advancement of the cable, and it is carried out in sequence. When the clamping wire traction mechanism 8 is recovered, the movable seat 804 in the load-bearing seat 803 must be pulled first. In the same transmission process as the above, the rotating clamping seat 807 must turn outward. The left and right clamping frames 809 on the rear side cross and rotate inward, and release the tightening of the rear part of the cable, thereby facilitating the resetting of the front structure of the clamping and pulling mechanism 8. The above-mentioned translation clamp seat 805 and the corresponding rotating clamp seat 807, as well as the clamping blocks on the left and right clamping frames 809 on the rear side, can also play the role of stopping the cable from returning. Because these clamping mechanisms are in the process of cable return, due to the effect of friction, the rotating clamp seat 807 driven by these clamping mechanisms has a rotation restriction, and the left and right clamping frames 809 are restricted from rotating inwardly, so the clamping mechanism can not only ensure the steady advancement of the cable, but also prevent the cable from escaping and returning. The sequential operation of several clamping and pulling mechanisms 8 can be controlled in sequence by an external remotely connected controller. This technical process is a well-known and common technical means in the art, so it will not be repeated. It can be achieved by controlling several groups of hydraulic cylinders 802 to work intermittently in batches to complete the graded advancement process of the cable of this application in sequence.

[0036] Furthermore, referring to Figure 4A slide groove corresponding to the load-bearing seat 803 is arranged inside the traction frame 4, and a corresponding opening is opened at the front end of the traction frame 4, and the wire clamping traction mechanism 8 enters and exits the traction frame 4 through the opening, and a limiting seat 14 is arranged at the opening, and the left and right sides of the lower side of the front end of the traction frame 4 are connected to the transfer block 11, and a torsion spring is arranged at the transfer point of the transfer block 11, and a conical clamping block 12 is arranged at the front end of the transfer block 11. The conical clamping block 12 and the torsion spring at the transfer point of the transfer block 11 are arranged, and the rear cable is conveniently pushed toward the front end of the equipment traction frame 4, and at the same time plays the role of a non-return cable, and a limit block 2 13 located on the inner side of the conical clamping block 12 is fixed to the lower side of the limiting seat 14, and the left side of the slide seat 801 The right outer end is rotatably connected to a positioning clamp 814, and a torsion spring is provided at the transition point of the positioning clamp 814, and a plurality of slots 7 corresponding to the positioning clamp 814 are provided on the left and right outer sides of the traction frame 4. The internal wire clamping and traction mechanism 8 of the present application can be reasonably configured in quantity and spacing according to the advancement distance and the length and weight of the cable. By pulling open the rotating block 11 connected to the conical clamp 12 on both sides, the limiting seat 14 on the traction frame 4 can be pulled out, and then the wire clamping and traction mechanism 8 can be loaded and unloaded. The positioning clamps 814 at both ends of the slide seat 801 and the corresponding slots 7 on the left and right outer sides of the traction frame 4 can conveniently fix the position of the wire clamping and traction mechanism 8.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
