Description

Technical Field

[0001] This utility model relates to the field of power transmission line erection technology, and in particular to a power transmission line erection device. Background Technology

[0002] Transmission lines are a crucial part of a power system for transmitting electrical energy. They typically transport power from power plants to load centers or serve as interconnecting lines between power systems. Transmission lines are erected between substations (switching stations) and power plants, and can be classified into overhead transmission lines and cable transmission lines according to their function, with overhead transmission lines being more common.

[0003] Currently, when power transmission lines are erected, it is usually necessary to use a shaft at a wire-laying frame to support a reel with the cable wound on it for the wire-laying operation. This type of wire-laying frame usually requires the shaft to pass through the reel, and then the reel is lifted and the shaft is installed on the support seat of the wire-laying frame for rotation. However, the reel with the power transmission cable wound on it is quite heavy, making the operation of laying the wire on the reel difficult, thus increasing the operational burden on the personnel erecting the power transmission lines. To address this, we propose a power transmission line erection device. Utility Model Content

[0004] The main objective of this invention is to provide a power transmission line erection device. By setting up an erection device for laying cable reels for power transmission line erection, this device can lift the cable reel, which is placed on the ground with a plug-in support shaft, and use a hydraulic cylinder in conjunction with a U-shaped seat to lift it up. This facilitates the laying and erection of power transmission lines, reduces the cumbersome laying operations for power transmission line erection personnel, and effectively solves the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A transmission line erection device includes a base plate, an extension frame, and side platforms. An extension frame is symmetrically welded to one side of the base plate, and side platforms are symmetrically welded to the outside of the extension frame. A hydraulic cylinder is bolted to the surface of each side platform, and a receiving plate is bolted to the telescopic rod of the hydraulic cylinder. A U-shaped seat is welded to the outside of the receiving plate, blocking the extension frame. Rotary grooves are distributed at three points within the U-shaped seat, away from the receiving plate. A fixed axis is welded within each rotary groove. A rotating cylinder is fitted onto the shaft body. A bolt is screwed onto the shaft head of the rotating cylinder. An L-shaped cover plate is fitted onto the top of the U-shaped seat, and a fixed rod protrudes from the lower surface of the L-shaped cover plate. A fixed hole for fitting the fixed rod is opened at the top of the U-shaped seat below the L-shaped cover plate. A guide plate is symmetrically welded to the base surface of the U-shaped seat, and a tube frame is symmetrically welded to the extension surface below the guide plate. The guide plate is inserted into the tube frame, and a pin hole for inserting a pin is opened through between the guide plate and the tube frame.

[0007] Furthermore, a side support plate is welded to the outer side of the frame away from the base plate and the side platform, and the surface of the side support plate is provided with plate holes.

[0008] By adopting the above technical solution, the side support plate welded on the outside of the extension frame can be pressed onto the ground, and then metal piles can be driven into some muddy ground through the holes in the side support plate to obtain support.

[0009] Furthermore, the L-shaped cover plate has an outward protrusion at the vertical plate body away from the U-shaped seat;

[0010] By adopting the above technical solution, the vertical plate of the L-shaped cover can accommodate the rotation of the shaft by means of a convex bulge.

[0011] Furthermore, connecting plates are welded between the frames of the pipe rack, and semi-circular grooves are recessed on both sides of the rack groove of the pipe rack, and semi-circular strips are symmetrically protruding on the outer surface of the guide plate.

[0012] By adopting the above technical solution, the pipe rack frames are firmly welded together with connecting plates. Then, when the pipe rack is clamped with the guide plate, the semicircular strip of the guide plate can slide within the semicircular groove of the pipe rack.

[0013] Furthermore, three sets of pin holes are vertically arranged on the surfaces of the guide plate and the tube rack;

[0014] By adopting the above technical solution, pins can be inserted into the three sets of pin holes on the guide plate and the tube rack surface for positioning connection.

[0015] Furthermore, the seat plate at the bottom of the hydraulic cylinder presses against the surface of the side platform, and the side platform and the seat plate at the bottom of the hydraulic cylinder are locked together by bolts;

[0016] By adopting the above technical solution, the seat plate of the hydraulic cylinder can be firmly locked to the side platform surface for installation with the help of bolts.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a cable reel laying device for power transmission line erection. This device can lift the cable reel, which is placed on the ground with a plug-in support shaft, and use a hydraulic cylinder in conjunction with a U-shaped seat to lift it up. This facilitates the laying and erection of power transmission lines and reduces the cumbersome laying operation for power transmission line erection personnel.

[0019] Furthermore, the three sets of pin holes on the guide plate and pipe rack of the erection device allow the pins to be inserted at different positions to fix the relative positions of the guide plate and pipe rack. Combined with the support of the hydraulic cylinder, this forms a double support position, enhancing the stability of the erection device when laying lines. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-3 As shown, a power transmission line erection device includes a base plate 1, an extension frame 2, and side platforms 3. The extension frame 2 is symmetrically welded to one side of the base plate 1, and side platforms 3 are symmetrically welded to the outside of the extension frame 2. A hydraulic cylinder 4 is bolted to the surface of each side platform 3, and a receiving plate 5 is bolted to the telescopic rod head of the hydraulic cylinder 4. A U-shaped seat 6 is welded to the outside of the receiving plate 5, blocking the extension frame 2. Rotary grooves 7 are distributed at three points within the U-shaped seat 6 away from the receiving plate 5. A fixed shaft 8 is welded into the rotary grooves 7, and a shaft body of the fixed shaft 8 is fitted with... The rotating drum 9 has a fixed shaft 8 protruding from the shaft head of the rotating drum 9 and screwed with a bolt. An L-shaped cover plate 10 is clamped on the top of the U-shaped seat 6, and a fixed rod 11 protrudes from the lower surface of the L-shaped cover plate 10. A fixed hole 12 for clamping the fixed rod 11 is opened at the top of the U-shaped seat 6 below the L-shaped cover plate 10. A guide plate 14 is symmetrically welded to the base surface of the U-shaped seat 6, and a tube frame 15 is symmetrically welded to the surface of the extension frame 2 below the guide plate 14. The guide plate 14 is inserted into the tube frame 15, and a pin hole 16 for inserting a pin 17 is opened through the guide plate 14 and the tube frame 15.

[0026] Among them, the outer side of the frame of the extension frame 2 away from the base frame plate 1 and the side platform 3 is welded with a side support plate 18, and the surface of the side support plate 18 is provided with plate holes.

[0027] By adopting the above technical solution, the side support plate 18 welded on the outside of the extension frame 2 can be pressed onto the ground, and then metal piles can be driven into some muddy ground through the holes of the side support plate 18 to obtain support.

[0028] Among them, the L-shaped cover plate 10 has a protrusion 13 protruding outward from the vertical plate body away from the U-shaped seat 6;

[0029] By adopting the above technical solution, the vertical plate of the L-shaped cover plate 10 can accommodate the rotation of the shaft with the convex bulge 13.

[0030] Among them, connecting plates are welded between the frames of the pipe rack 15, and semi-circular grooves are recessed on both sides of the rack groove of the pipe rack 15. Semi-circular strips are symmetrically protruding on the outer surface of the guide plate 14.

[0031] By adopting the above technical solution, the frames of the pipe rack 15 are firmly welded together with connecting plates. Then, when the pipe rack 15 is clamped with the guide plate 14, the semicircular strip of the guide plate 14 can slide within the semicircular groove of the pipe rack 15.

[0032] Among them, three sets of pin holes 16 are vertically arranged on the surface of the guide plate 14 and the tube rack 15;

[0033] By adopting the above technical solution, pins 17 can be inserted into the three sets of pin holes on the surface of the guide plate 14 and the pipe rack 15 for positioning connection.

[0034] The bottom plate of the hydraulic cylinder 4 presses against the surface of the side platform 3, and the side platform 3 and the bottom plate of the hydraulic cylinder 4 are locked together by bolts.

[0035] By adopting the above technical solution, the seat plate of the hydraulic cylinder 4 can be firmly locked to the surface of the side platform 3 for installation with the help of bolts.

[0036] It should be noted that this utility model is a transmission line erection device. After the hydraulic cylinder 4 is installed on the side platform 3 at the extension 2 of the base frame plate 1, the top telescopic rod of the hydraulic cylinder 4 can be locked to the receiving plate 5 on the outside of the U-shaped seat 6 by screws. Then, the U-shaped seat 6 is inserted into the pipe rack 15 with the guide plate 14. At the same time, the extension 2 is supported by the side support plate 18 pressing against the ground. When the cable reel for transmission line erection needs to be erected by passing through the support shaft, the telescopic rod of the hydraulic cylinder 4 can be lowered to the lowest position. Then, the cable reel, carrying the support shaft, rolls between the extension 2, so that the support shaft of the cable reel is above the U-shaped seat 6. Then, the hydraulic cylinder 4 extends the telescopic rod upward, so that the receiving plate 5 carries the U-shaped seat 6 to rise. Under the support of the U-shaped seat 6, the U-shaped seat 6 can carry the support shaft to rise. After the support shaft carries the cable reel off the ground, after one set of pin holes 16 of the guide plate 14 and the pipe rack 15 are aligned, the pin 17 can be inserted into the guide plate 14 and the pipe rack 15. The cable reel is positioned and supported in the pin hole 16 of the pipe rack 15. At this time, the cable reel can rotate at the rotating drum 9 of the U-shaped seat 6 with the help of the support shaft, so that the cable for the power transmission line can be smoothly released from the cable reel. When the rotating drum 9 rotates at the fixed shaft 8, it can support the support shaft of the cable reel for smooth rotation. With the double lifting support of the pin 17 and the hydraulic cylinder 4, the support shaft at the U-shaped seat 6 can obtain stable support. If necessary, the L-shaped cover plate 10 can be placed on the top of the U-shaped seat 6. The L-shaped cover plate 10 is positioned and locked at the fixed hole 12 of the U-shaped seat 6 with the fixed rod 11, so that the two ends of the support shaft at the U-shaped seat 6 are restricted by the L-shaped cover plate 10, preventing the support shaft of the cable reel from coming off at the U-shaped seat 6. After the cable is released, the L-shaped cover plate 10 can be removed, and then the pin 17 can be pulled out. The U-shaped seat 6 can be lowered normally. After the cable reel touches the ground, the U-shaped seat 6 can be lowered away from under the support shaft, so as to facilitate the removal of the cable reel for the power transmission line.
