Description

Technical Field

[0001] The present invention relates to the technical field of transmission line construction, and particularly relates to a crawler-type spanning netting equipment. Background Art

[0002] During the construction of high-voltage transmission lines, it is often necessary to span residential houses, bridges, roads, railways, etc. In order to ensure the normal progress of transmission line construction, it is necessary to carry out wire stringing netting construction across these facilities. However, traditional spanning frames cannot meet the construction requirements due to disadvantages such as poor safety, large overall weight, low automation level, slow netting / denetting speed, etc.; in addition, when using traditional netting equipment, the protective net needs to be towed while being hung, resulting in low installation efficiency due to complex installation; furthermore, when encountering long-distance spans, relatively heavy weights are often required to stabilize the equipment, which in turn makes the equipment cumbersome to transfer and consumes high energy.

When the telescopic arm is horizontally unfolded, the driving tooth belts one 25 and two 26 on the first-level arm 15, or the second-level arm 16, or the third-level arm 17, or the fourth-level arm, or the last-level arm 18 are at different horizontal heights. The driving tooth belt one 25 is used to drive the rotation of the first gear 24-5 corresponding to one of the winglets 24-4 in the netting assembly 24, and the driving tooth belt one 25 is used to drive the rotation of the second gear 24-9 corresponding to the other winglet 24-4 in the netting assembly 24.

[0052] The above-mentioned second winding mechanism 19-5 includes a winding roller rotatably provided inside the last-level arm 18. The winding roller is driven to rotate by a second servo motor. A second winding rope 19-6 is wound around the winding roller. The free end of the second winding rope 19-6 is connected to the vertical support arm 19.

[0053] The above-mentioned vertical support arm 19 includes a mother cylinder 19-1 whose top end is hinged to the final-stage arm 18. A sub-cylinder 19-2 is slidably arranged in the mother cylinder 19-1. A first winding mechanism 19-3 for the sub-cylinder 19-2 is arranged in the mother cylinder 19-1. The first winding mechanism 19-3 includes a first winding roller around which a first winding rope 19-4 is wound. The first winding roller is driven to rotate by a first servo motor. The free end of the first winding rope 19-4 is connected to the top end of the sub-cylinder 19-2. A one-way limiting mechanism 19-8 is arranged between the mother cylinder 19-1 and the sub-cylinder 19-2. The one-way limiting mechanism 19-8 includes a positioning rack 19-7 fixed on the sub-cylinder 19-2. A one-way limiting mechanism 19-8 for the positioning rack 19-7 is arranged in the mother cylinder 19-1. The one-way limiting mechanism 19-8 includes a main body rod 19-8-1. An installation groove is formed on the main body rod 19-8-1. Multiple support rods 19-8-2 are arranged in the installation groove. A toothed plate 19-8-3 corresponding to the positioning rack 19-7 is hinged on the support rod 19-8-2. A limiting rod 19-8-4 corresponding to each toothed plate 19-8-3 is arranged on the main body rod 19-8-1. A torsion spring 19-8-5 for forcing the corresponding toothed plate 19-8-3 to fit with the corresponding limiting rod 19-8-4 is arranged on the support rod 19-8-2. A first guide rod 19-9 and a guide post 19-11 penetrating through the side wall of the mother cylinder 19-1 are arranged on the main body rod 19-8-1. An electric push rod 19-10 is arranged outside the mother cylinder 19-1. The telescopic end of the electric push rod 19-10 is connected to the guide post 19-11.

[0054] By controlling the position of the main body rod 19-8-1 in the one-way limiting mechanism 19-8, the toothed plate 19-8-3 can be made to contact the rack, thereby realizing the limitation of the position of the sub-cylinder 19-2 and effectively preventing the sub-cylinder 19-2 from retracting upward when it contacts the ground to play a supporting role.

[0055] It should be noted that the above-mentioned various electrical devices are all electrically connected to the controller 44.

[0056] Specific working principle of the present invention: When it is necessary to build a net-erecting spanning frame, first move the crawler vehicle 1 to the construction position, then pull out the telescopic frame 2 to a proper position, control the telescopic end of the support hydraulic cylinder 3 to extend through the controller 44, and then control the first driving motor 7 to rotate so that the base 6 rotates to a proper position. Then, control the telescopic ends of the first hydraulic cylinder 10 and the second hydraulic cylinder 14 to extend through the controller 44 so that the vertical frame 8 is in a vertical state and the telescopic arm is in a horizontal state. Then, start the third servo motor 29-3 in the basic arm 13 through the controller 44 so that the first-stage arm 15 extends outwards. When the end plate 31-1 on the first-stage arm 15 contacts the proximity switch 31-3 on the limit plate 31-2 in the basic arm 13, the controller 44 shuts down the third servo motor 29-3 and simultaneously energizes the electromagnet to fix the positions between the basic arm 13 and the first-stage arm 15. And so on until the last-stage arm 18 is unfolded. After the last-stage arm 18 is unfolded, the controller 44 controls the second winding mechanism 19-5 to release the vertical support arm 19 to make it in a vertical state, and then adjusts the position of the main rod 19-8-1 through the electric push rod 19-10 so that the toothed plate 19-8-3 on the main rod 19-8-1 can contact the positioning rack 19-7, and then the first winding mechanism 19-3 releases the sub-cylinder 19-2 downwards.

[0057] In addition, when the first-stage arm 15 extends outwards, under the action of the first driving belt 25 and the second driving belt 26, the wing 24-4 in the net-spreading assembly 24 on the basic arm 13 opens, and further the side rod 24-3 pulls out the protective net 24-8. And so on until the last-stage arm 18 extends outwards, the wing 24-4 in the net-spreading assembly 24 on the third-stage arm 17 opens, and the side rod 24-3 pulls out the protective net 24-8.

[0058] It should be noted that when the first-stage arm 15 is unfolded, the driving rack 28 drives the second gear to rotate, and the second gear drives the first gear to rotate, so that the balance arm 27 is in a vertical state.

[0059] In addition, the last-stage arm 18 drives the balance rope 33 to be released from the rope reel 35, and the balance rope 33 drives the friction wheel 40-3 to rotate, so as to drive the lead screw 39-3 to rotate, thereby adjusting the position of the counterweight 39-6.

[0060] When the spanning frame needs to be retracted, first retract the vertical support arm 19. That is, first use the electric push rod 19-10 to retract the main rod 19-8-1 in the one-way limit mechanism 19-8 so that the toothed plate 19-8-3 disengages from the positioning rack 19-7. Then, use the winding mechanism one 19-3 to retract the sub-cylinder 19-2. Next, use the winding mechanism two 19-5 to retract the vertical support arm 19 into the final stage arm 18. Then, first cut off the power supply of the electromagnet between the final stage arm 18 and the third stage arm 17, and retract the final stage arm 18. Then, drive the rope reel 35 to rotate by the drive motor two 38, so that a part of the balance rope 33 is retracted. At the same time, the counterweight 39-6 moves a certain distance in the direction close to the transmission assembly 40. In this way, the third stage arm 17, the second stage arm 16, and the first stage arm 15 are retracted successively.

[0061] It should be noted that when the final stage arm 18 is retracted, the net spreading assembly 24 on the third stage arm 17 is retracted, so that until the net spreading assembly 24 on the basic arm 13 is retracted. In addition, when the first stage arm 15 is retracted, the balance arm 27 gradually tilts.

[0062] Next, the first hydraulic cylinder 10 retracts to make the vertical frame 8 tilt, and then the second hydraulic cylinder 14 retracts to make the basic arm 13 fall towards the vertical frame 8.

[0063] Finally, retract the telescopic end of the support hydraulic cylinder 3, and push the telescopic frame 2 into the crawler vehicle 1.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still can modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
