Description
Technical Field
The utility model relates to a shaft tower assemblage auxiliary device especially relates to an adjustable shaft tower assemblage auxiliary hoisting device.
Background
With the increasing year by year of the investment of the rural power grid transformation and upgrading engineering, the engineering construction task is heavier and heavier, and the tower assembly work becomes a key part of the engineering construction. When the tower is assembled, the upper part of the tower on the ground needs to be suspended in the air, and the hardware is installed on the upper part of the tower suspended in the air. The traditional mode of hovering the tower in the air is crane hoisting or tripod supporting, the crane hoisting mode has large engineering quantity, long operation time and low tower assembling efficiency; the mode structure that the tripod supported is unstable, and the shaft tower is emptyd easily, has the potential safety hazard.
Disclosure of Invention
The utility model relates to a solve above-mentioned technical problem, provide an adjustable shaft tower assemblage auxiliary hoisting device, its simple structure, convenient operation can shorten the activity duration, improves shaft tower assemblage efficiency, and the structure is firm, avoids the shaft tower to empty, improves the operation security.
The technical solution of the utility model is that:
adjustable shaft tower assemblage auxiliary lifting device, including the base, its special character lies in: the base is provided with a jack, the top end of a piston rod of the jack is provided with a bracket with an upward opening, a bearing frame is arranged on the piston rod of the jack, and clamping arms which move relatively and a driving mechanism which drives the two clamping arms to move relatively are respectively arranged on the bearing frame and positioned at the two sides of the bracket.
Preferably, the bracket is arc-shaped, riding wheels are uniformly distributed on the bracket, and the riding wheels rotate along the radial direction of the bracket.
Further preferably, the bearing frame is sleeved on a piston rod of the jack, so that the height of the bearing frame can be conveniently adjusted.
Preferably, the clamping pieces are respectively arranged on the opposite surfaces of the two clamping arms and are arc-shaped, so that the contact area between the clamping pieces and the tower is increased.
Preferably, the clamping piece and the corresponding clamping arm are vertically and rotatably mounted, so that the inner arc surface of the clamping piece is adaptively attached to the outer circular surface of the tower.
Preferably, the driving mechanism is a screw rod, the screw rod is connected with the two clamping arms through threads, and the thread directions of the two sides of the screw rod are opposite.
Preferably, a hand wheel is arranged at the end, penetrating out of the bearing frame, of the screw rod, so that the screw rod can be conveniently rotated.
The utility model has the advantages that:
support shaft tower upper portion through the bracket, adjust shaft tower upper portion height through the jack to through the fixed shaft tower of arm lock centre gripping, simple structure, convenient operation has shortened the activity duration, has improved shaft tower assemblage efficiency, and the structure is firm, avoids the shaft tower to empty, has improved the operation security.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a view of the clip and clip arm connection of FIG. 1;
in the figure: the device comprises a base 1, a jack 2, a bracket 3, a riding wheel 4, a bearing frame 5, a clamping arm 6, a lead screw 7, a hand wheel 8 and a clamping piece 9.
Detailed Description
As shown in fig. 1 and 2, the adjustable tower assembly auxiliary lifting device comprises a base 1, a jack 2 is mounted on the base 1, a bracket 3 with an upward opening and an arc shape is mounted at the top end of a piston rod of the jack 2, riding wheels 4 are uniformly distributed on the bracket 3, and the riding wheels 4 rotate along the radial direction of the bracket 3; a bearing frame 5 is sleeved on a piston rod of a jack 2, two sides of a bracket 3 on the bearing frame 5 are respectively provided with a clamping arm 6 which moves relatively and a lead screw 7 which is connected with the two clamping arms 6 through threads, the directions of the threads on the two sides of the lead screw 7 are opposite, the lead screw 7 penetrates through the end of the bearing frame 5 and is provided with a hand wheel 8, and opposite surfaces of the two clamping arms 6 are respectively provided with an arc-shaped clamping piece 9 which rotates up and down.
During operation, the upper part of a tower on which the ground is placed is supported on the riding wheels 4 of the bracket 3, then the bearing frame 5 is adjusted in height, the two clamping arms 6 are adjusted to move relatively through the lead screw 7, the clamping pieces 9 on the two clamping arms 6 clamp the outer circle surface diameter of the tower, the jack 2 is started again to lift the upper end height of the tower, the bearing frame 5 is lifted in a self-adaptive mode, the two clamping pieces 9 rotate in a self-adaptive mode in the lifting process of the upper part of the tower, the tower is prevented from sliding downwards under the clamping force action of the two clamping pieces 9, and finally hardware fittings are installed on the upper part of the tower.
The above description is only an example of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
