Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pole transportation, in particular to a concrete pole outer protective frame for concrete pole transportation. Background Art

[0002] Concrete poles are what we usually call electric poles, which support power lines with the help of hardware accessories such as cross arms fastened on the concrete poles. The function of concrete poles is to support power lines with the help of hardware accessories such as cross arms fastened on the concrete poles. After the concrete poles are produced, they need to be loaded and transported. During the transportation process, the concrete poles are easily damaged due to lack of protective measures. Therefore, a concrete pole outer protective frame is needed for the transportation of concrete poles.

[0003] After research and analysis, it was found that during the loading and transportation process of existing concrete poles, the concrete poles are lifted and loaded by directly connecting the steel cables of the crane to the concrete poles. After loading, they are stacked in the cargo hold of the transport vehicle. There is a lack of fixing and protection measures, which can easily cause the concrete poles to be damaged or moved by external forces during transportation, resulting in low safety of transportation work. In addition, after transportation and unloading, the concrete poles need to be moved a short distance for placement. This distance requires workers to push the concrete poles to move, which is very laborious. Utility Model Content

The top of the base 1 is provided with a slide rail 3, both sides of the slide rail 3 are slidably provided with an outer guard seat 4, both sides of the upper side of the slide rail 3 are rotatably provided with a screw rod 301, one end of the screw rod 301 is welded with a hand crank 302, and the end of the hand crank 302 is provided with a screw rod 301. A ratchet is arranged at the outer edge, and a pawl is installed on one side of the slide rail 3 near the outer side of the hand-cranked disk 302 through a rotating shaft and a torsion spring, and the front end of the pawl fits with the ratchet. A movable hoop 5 is arranged on the outside of the outer guard 4, and a threaded rotating rod 6 is threadedly connected to one side of the movable hoop 5, and the bottom end of the threaded rotating rod 6 is rotatably connected to one side of the outer guard 4 through a bearing, a nut 601 is threadedly connected to the outer side of the threaded rotating rod 6, and a movable splint 502 is installed on the inner side of the movable hoop 5 through a threaded rod 501, and the threaded rod The movable plate 502 is driven by the movable rod 501 to move, so that the inner wall of the movable plate 502 is fully in contact with the concrete rod, and the friction between the two is increased by the contact with the protective pad 503, so that the concrete rod is protected and fixed.

[0023] Reference Figure 1 , 2 4. In this embodiment, the lifting mechanism includes an anti-foolproof mounting block 102, an anti-foolproof mounting groove 201, and a carabiner 8, wherein the four corners of the top of the base 1 are provided with anti-foolproof mounting blocks 102, the four corners of the bottom of the top plate 2 are provided with anti-foolproof mounting grooves 201, and the anti-foolproof mounting blocks 102 are arranged in an isosceles trapezoidal shape, and the anti-foolproof mounting blocks 102 and the anti-foolproof mounting grooves 201 are matched with each other, and the four corners of the top of the top plate 2 are installed with carabiners 8, and the fixed concrete poles can be moved by the brake casters 101.

[0024] Reference Figure 1 , 2In this embodiment, a latch 7 is movably provided between the movable hoop 5 and the outer guard seat 4 .

[0025] Reference Figure 1-3 In this embodiment, the protective pad 503 is a protective pad 503 made of rubber material. Since rubber material has a large friction coefficient, using it as the material of the protective pad 503 can effectively increase the friction between the protective pad 503 and the outer wall of the concrete pole, thereby further improving the fixing efficiency of the passage. At the same time, through the high deformability and protection of rubber itself, using it as the material of the protective pad 503 can further improve the protection efficiency of the fixed passage.

[0026] Working principle: First, the worker hoists the concrete rod by hoisting and places it inside the two outer guard seats 4. The screw rod 301 is driven to rotate by rotating the hand-cranked disks 302 on both sides, and the outer guard seats 4 can be driven to move under the guidance of the slide rails 3. When not in use, the hand-cranked disk 302 can be limited by the engagement of the ratchet teeth of the hand-cranked disk 302 with the outer pawls to prevent the screw rod 301 from rotating in the opposite direction under pressure. The spacing between the two outer guard seats 4 is adjusted according to the size of the concrete rod, and then the two movable hoops 5 are rotated back to their original positions under the action of the threaded rotating rod 6 and the bearing, and then the pin 7 is inserted to penetrate the movable hoop 5 and the outer guard seat 4, and then the threaded rotating rod 6 is rotated to drive the movable hoop 5 Move under the guidance of the pin 7 to adjust the distance between the outer protective seat 4 and the movable hoop 5. Finally, the movable splint 502 is driven to move by rotating the threaded rod 501 so that the inner wall of the movable splint 502 is in full contact with the concrete rod. The pad 503 is used to increase the friction between the two through contact to protect and limit the concrete rod. Afterwards, the fixed concrete rod can be moved by the brake caster 101. When the fixed concrete rod needs to be loaded and transported, the steel cable used for lifting can be connected to each carabiner 8, and then the bolts fixing the threaded ears of each base 1 and the top plate 2 are unscrewed, and the crane is controlled to lift the top plate 2, and the fixed concrete rod is lifted and loaded.
