Description

Burst wind tower transports frock
Technical Field
The invention relates to a segmented wind tower transferring tool.
Background
The Vestas segmented wind tower is a novel wind tower, is a wind tower which is formed by connecting 3 120-degree cylinders into a whole circle by using fasteners, and is different from a common wind tower when being transported to a wharf after being manufactured. Due to the particularity of the transportation of the segmented wind tower, if the operation of turning over once is required on the wharf according to the mode of transporting the platform wind tower, the wharf does not have the condition for the operation; in addition, the fragmentation tower runs the risk of slipping during transport.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a transportation tool for a segmented wind tower, which is provided with a convex arc saddle and can ensure that the segmented tower is in a horizontal state.
In order to achieve the purpose, the technical scheme of the invention is to design a split wind tower transfer tool which comprises at least two tool bodies, wherein each tool body comprises a lower tool half part of a frame structure and an upper tool half part of a circular arc plate type, and the lower half part is fixedly connected with the upper half part; a plurality of sections of anti-skid lines are arranged on the surface of the upper half part, which is in contact with the inner side wall of the segmented wind tower, at intervals; the lower half part is connected with a sliding deceleration structure of the slicing tower. The convex arc saddle seat (namely the lower half part of the arc plate part and the frame structure) is designed, the contact area between the conical tower and the saddle is increased as much as possible during design, the height of the saddle and the arrangement distance of 2 saddles are adjusted, and the slicing tower is ensured to be in a horizontal state; under the condition of meeting the strength requirement, the weight of the saddle is reduced as much as possible, and a frame structure with the section as the main part is adopted in the design.
The further technical scheme is that the upper half part comprises an arc plate matched with the inner side wall of the segmented wind tower and a vertical protection plate fixedly connected to the edge of the arc plate. Like this the arc board is close to the level and arranges, and the vertical setting of vertical protection shield avoids when the adjustment action before the burst wind tower is placed because the idol collides with the arc board during burst wind tower adjustment position, avoids the edge that the arc board was touched to the burst wind tower through setting up vertical protection shield, plays the effect of protection.
The further technical scheme is that the lower half portion comprises a plurality of channel steel transverse and longitudinal cross fixed connection bodies, and the upper end of the lower half portion is fixedly connected to the vertical protection plate.
The technical scheme is that the anti-skid grains are arranged at intervals along the length direction of the circular arc plate, and the length of the anti-skid grains is consistent with the width of the circular arc plate; the tool body is fixedly connected to the flat car. After setting up like this, the burst wind tower can be more stable after placing on this frock, and the difficult landing that spends has improved the security of this frock.
The sliding and decelerating structure of the slicing tower comprises connecting rods fixedly connected to channel steel at two ends of the lower half part, two connecting rods are respectively connected to the channel steel at the leftmost end and the channel steel at the rightmost end, a friction wheel is rotatably arranged on each connecting rod, the wheel diameters of the two friction wheels are gradually reduced from outside to inside, and the height of the friction wheel with the larger wheel diameter is lower than the lower edge of the arc plate; the rubber stick of L shape is fixed to be set up on the friction pulley of less wheel footpath, and rubber stick one end fixed connection is on the wheel face of friction pulley, and the other end sets up towards burst wind tower inside wall. After setting up like this, big friction pulley is located the below of circular arc board, can not contact burst wind tower inside wall when placing burst wind tower adjustment position, can not disturb this action of adjustment position, and < must appear the opposite side perk when the burst wind tower slides to one side also this one side burst wind tower leans on the inboard condition of circular arc board, will contact big friction pulley like this > can contact big friction pulley, make big friction pulley rotate, drive the little friction pulley rather than frictional contact from this, lower friction pulley rotates and then drives the tip of L shape rubber stick and lean on the inside wall that the burst wind tower leaned on, consequently, can play the speed that slows down burst wind tower landing when burst wind tower landing, play certain guard action. The T-shaped through hole can be further formed in the L-shaped rubber rod body and comprises a transverse hole and a longitudinal hole, the orifice of the longitudinal hole is located at the end portion, facing the inner side wall of the separation wind tower, of the L-shaped rubber rod, the alarm piece made of soft rubber is arranged in the transverse hole, one end of the alarm piece made of soft rubber is fixedly connected to the inner wall of the transverse hole, a driven rod abutting against the alarm piece made of soft rubber is arranged in the longitudinal hole, the driven rod is made of hard rubber, one end of the hard rubber abuts against the alarm piece made of soft rubber, the other end of the hard rubber exceeds the orifice of the longitudinal hole, the hole, provided with the Venturi tube, in the alarm piece is used for enabling the alarm piece to be extruded by the driven rod to form air flow when the L-shaped rubber rod abuts against the inner side wall of the.
The invention has the advantages and beneficial effects that: after the antiskid lines are arranged, the partitioned wind tower can be more stable after being placed on the tool, is not easy to flower and slide, and improves the safety of the tool. Big friction pulley is located the below of circular arc board, can not contact burst wind tower inside wall when placing burst wind tower adjustment position, can not disturb this action of adjustment position, and < must appear when the burst wind tower is to one side landing that the opposite side perk also the burst wind tower of this one side leans on the inboard condition to the circular arc board, will contact big friction pulley like this > can contact big friction pulley, make big friction pulley rotate, from this drive rather than the little friction pulley of frictional contact, lower friction pulley rotates the tip that then drives L shape rubber stick and supports the inside wall that leans on burst wind tower, consequently, can play the speed that slows down burst wind tower landing when burst wind tower landing, play certain guard action. The invention designs the convex arc saddle seat, increases the contact area of the cone tower and the saddle as much as possible, can ensure that the slicing tower is in a horizontal state, and maximally reduces the weight of the saddle.
