Description

Technical Field

[0001] The invention relates to the field of electric power engineering, and in particular to an electric conductor insulation support rod trolley for live pole erection projects. Background Art

[0002] In the field of power infrastructure construction and maintenance, live pole erection of 10kV lines is a challenging and critical task. With the acceleration of urbanization, electricity demand continues to rise, and it is urgent to ensure the efficient laying and stable operation of 10kV lines. Lines of this voltage level are like the "power arteries" of the city, penetrating into the streets and alleys, providing daily electricity for residential communities and lighting up thousands of homes; helping the machines in factory workshops roar and maintaining the continuity of industrial production; empowering public service institutions such as hospitals and schools to ensure social order.

[0003] During the process of erecting poles on 10kV lines, the working method is to use a crane to lower the pole vertically from the middle of the 10kV line. During the lowering of the pole, in order to prevent the pole from scratching the 10kV line and reduce the risk of pole breakage and conductor breakage and the requirement of safe distance, the distance between the two circuits of the 10kV line should be supported to facilitate the placement of the pole from above the conductor. At present, the conventional practice is for the staff to wrap the phase line of each circuit of the line with insulating sheath materials on the live working vehicle, and then the ground personnel install anchor piles on the ground, and then tie the insulating rope to each phase line and fix it on the ground anchor pile. When working in this way, it is necessary to consider in advance the horizontal stress of the conductor, sag, the phase-to-phase distance of each line and the safe distance of the line after anchoring. Usually, 2 workers are required to work on the live working vehicle and 2 to 3 workers are required to work on the ground. A total of 6 pull wires and 6 anchor piles are required. In addition, considering the balance of conductor force and the safe distance, it takes about 90 minutes to support the distance between the two lines of the 10kV line. It is time-consuming, labor-intensive and requires a large number of people. In addition, the safe distance of the line cannot be controlled during the pulling process, and there is a risk of phase-to-phase short circuit, which causes harm to personal and equipment safety.

[0018] 5.

DETAILED DESCRIPTION

[0029] The present invention discloses an electric wire insulating support rod trolley for live pole erection projects, which is mainly composed of a lifting vehicle 1, a work plate 2, two insulating telescopic rods 3, and four insulating clamps 4, wherein the work plate 2 is installed on the lifting vehicle 1, and two slideways 21 are arranged on the work plate 2.

[0030] The two insulating telescopic rods 3 are respectively connected to the two slideways 21 of the working plate 2 in a sliding manner, each insulating telescopic rod 3 includes a first insulating rod 31 and a second insulating rod 32 that can slide relative to each other, and two of the four insulating clamps 4 are respectively arranged on the first insulating rod 31 and the second insulating rod 32 of the same insulating telescopic rod 3. A limiting groove 22 is provided in the slideway 21, and a limiting block is provided on the first insulating rod 31. The limiting groove 22 is slidably connected to the limiting block to play a role of sliding guide. At the same time, a threaded seat 33 is provided on one side of the first insulating rod 31 of the insulating telescopic rod 3, and the threaded seat 33 is provided with a through threaded hole. Correspondingly, two rotating mounting seats 5 are fixedly connected to the working plate 2, and each rotating mounting seat 5 is rotatably mounted with a first lead screw 6. The two first lead screws 6 are respectively threadedly connected to the threaded seats 33 set on the corresponding first insulating rods 31 in the two insulating telescopic rods 3, and the working plate 2 is also fixedly installed with two first motors 7, and the output shafts of the two first motors 7 are respectively fixedly connected with the corresponding first lead screws 6, so as to control the movement of the insulating telescopic rod 3.

[0031] The first insulating rod 31 is also provided with a sliding groove 34, in which a sliding connection block 35 is slidably installed, and the sliding connection block 35 is provided with a through threaded hole, which is used to set the insulating clamping claw 4 on the first insulating rod 31 of the insulating telescopic rod 3, and the first insulating rod 31 is provided with a second motor 8, and the second lead screw 9 is rotatably installed in the second sliding groove 34, and the second motor 8 drives the second lead screw 9 coaxially, and the second lead screw 9 is threadedly connected with the sliding connection block 35, so as to adjust the position of the insulating clamping claw 4. The second insulating rod 32 is fixedly connected with a fixed connection block 36, which is used to set the insulating clamping claw 4 on the second insulating rod 32, and the second insulating rod 32 is provided with a threaded hole, and the first insulating rod 31 is rotatably installed with a third lead screw 38, and the first insulating rod 31 is also provided with a third motor 37, and the third motor 37 coaxially drives the third lead screw 38, and the third lead screw 38 is threadedly connected with the second insulating rod 32, so as to realize the extension and retraction of the second insulating rod 32 relative to the first insulating rod 31. The components of the overall structure work together to meet the needs of conductor insulation support in live pole projects.

[0032] The insulating clamp 4 includes a connecting block 41, a heightening block 42 is fixedly connected to the connecting block 41, a connecting plate 43 is fixedly connected to the heightening block 42, a rotating mounting plate 44 is fixedly connected to one side of the connecting plate 43, and a clamping plate 45 is fixedly connected to the other side, and an opening is provided on the connecting plate 43. A macro camera 10 is provided on one side of the rotating mounting plate 44 for auxiliary observation, and a left L-shaped hook 46 and a right L-shaped hook 47 are rotatably installed on the other side. The left L-shaped hook 46 and the right L-shaped hook 47 are both provided with tooth blocks, and the tooth blocks of the two mesh with each other for clamping the wire. An open bayonet 49 is provided on the clamping plate 45 for auxiliary positioning of the wire; a micro cylinder 48 is rotatably installed on the connecting block 41, and the micro cylinder 48 passes through the opening of the connecting plate 43, and its telescopic rod is rotatably connected to the left L-shaped hook 46.

[0033] When the present invention is in use, it is necessary to select a suitable path to transport the lift 1 equipped with the electric wire insulation support rod trolley to the area below the wire according to the construction site planning of the live pole project and the specific location of the wire. During transportation, it is necessary to always pay attention to the environmental conditions on site, such as avoiding potholes, protrusions and other obstacles on the ground that may affect the smooth travel of the lift. At the same time, it is also necessary to ensure that a sufficient safety distance is maintained from other surrounding live equipment, buildings, etc. to prevent accidents such as collisions and electric shocks. After the lift 1 arrives at the appropriate position under the wire, it needs to be parked firmly, the support feet are lowered, the handbrake is pulled up, etc., to ensure that the lift will not move accidentally during subsequent operations, and provide a stable and reliable basic platform for subsequent operations.

[0034] After parking, the lifting function of the lifting vehicle 1 is operated. The operator can use the control device of the lifting vehicle 1 to slowly and accurately control the lifting vehicle 1 to drive the work board 2 to rise according to the approximate height information of the wire obtained from the project construction drawings and other channels. During the rising process, pay close attention to the relative position of the work board 2 and the surrounding environment and the wire to prevent the work board 2 from colliding with the wire or other objects due to excessive rising speed or improper operation, until the work board 2 is lifted to a suitable level roughly close to the height of the wire, so that the subsequent insulating telescopic rod 3 and insulating clamping claws 4 and other components can be in a reasonable position range for easy operation of the wire, and prepare for further precise operation.

[0035] Next, start the two first motors 7 on the work plate 2, and the first motor 7 drives the corresponding first lead screw 6 to rotate. Since the first lead screw 6 is in a threaded connection with the threaded seat 33 on the first insulating rod 31 of the insulating telescopic rod 3, under the rotation of the lead screw, the insulating telescopic rod 3 will slide, extend or contract along the slideway 21 of the work plate 2, and the limit groove 22 in the slideway 21 and the limit block of the first insulating rod 31 slide to ensure the accuracy of its sliding direction. The operator can move the insulating telescopic rod 3 to a suitable working position by controlling the forward and reverse rotation and rotation duration of the first motor 7 according to the specific position and height of the wire in the actual live pole project. At the same time, if it is necessary to further adjust the telescopic length of the second insulating rod 32 in the insulating telescopic rod 3 relative to the first insulating rod 31, the third motor 37 set in the first insulating rod 31 can be started, and the third motor 37 coaxially drives the third lead screw 38 to rotate. Due to the threaded connection between the third lead screw 38 and the second insulating rod 32, the second insulating rod 32 can be extended and retracted relative to the first insulating rod 31, thereby accurately adjusting the overall length of the insulating telescopic rod 3 to better adapt to the distance requirements for wire support under different working conditions, ensuring that the insulating telescopic rod 3 can be accurately extended to a position that is convenient for the insulating clamp 4 to contact and operate the wire.

[0036] After the insulating telescopic rod 3 is moved into position, it is necessary to select the insulating clamps 4 on different insulating rods for operation according to the spacing between the wires. When the wire spacing is relatively short, it is preferred to use the set of insulating clamps 4 installed on the first insulating rod 31. Start the second motor 8 on the first insulating rod 31, and the second motor 8 drives the second lead screw 9 to rotate. Since the second lead screw 9 is threadedly connected to the sliding connection block 35, the sliding connection block 35 will slide in the sliding groove 34, thereby driving the insulating clamps 4 to move to the appropriate position on the first insulating rod 31. Then use the macro camera 10 on this set of insulating clamps 4 to assist in observing the specific position of the wire, and use the open bayonet 49 of the clamping plate 45 to assist in positioning the wire to ensure that the insulating clamps 4 can accurately align with the wire. Then, the micro cylinder 48 is started, and the telescopic rod of the micro cylinder 48 pushes the left L-shaped hook 46 to rotate. Since the tooth blocks of the left L-shaped hook 46 and the right L-shaped hook 47 are meshed, the left L-shaped hook 46 will drive the right L-shaped hook 47 to move synchronously when it rotates, and the two cooperate with each other to clamp the wire and realize reliable insulation support for the wire. When the wire spacing is relatively long, the set of insulating clamps 4 installed on the second insulating rod 32 is selected. The third motor 27 in the first insulating rod 31 is started, and the third motor 37 drives the third lead screw 38 to rotate. Since the third lead screw 38 is threadedly connected to the second insulating rod 32, the second insulating rod 32 slides in the first insulating rod 31 and drives the fixed connection block 36 to move to a suitable position. Subsequently, the corresponding macro camera 10 is used to observe the wire position, and after positioning the wire through the open bayonet 49, the micro cylinder 48 is started to make the left L-shaped hook 46 and the right L-shaped hook 47 cooperate to clamp the wire, completing the insulation support operation for the wire with a longer spacing.
