Background technique

When the hollow plate is prestressed, it is necessary to install a jack and remove the jack for each strand of steel strands, and the jack also needs to be fixed on a stable bearing bracket; it is time-consuming and laborious. Therefore, the invention A device for rapidly moving prestressed tensioning jacks in multiple directions, improving the installation and dismantling speed of each hollow plate jack and improving the efficiency of prestressed tensioning operations, has become a problem to be solved.

Utility model content

The purpose of the utility model is to propose a multi-directional moving device of the prestressed tensioning jack, which can improve the installation and dismantling speed of each hollow plate jack and improve the prestressed tensioning operation efficiency.

The utility model adopts the following technical scheme for accomplishing the above-mentioned purpose:

A multi-directional moving device of a prestressed tensioning jack, the multi-directional moving device has a bearing bracket base arranged on a hollow board to be stretched; the bearing bracket base is arranged on one end of the hollow board to be stretched. the top; the support base is fixed with a support bracket column perpendicular to the hollow plate to be stretched; the top of the support bracket column is fixed with a support bracket beam; one end of the support bracket beam It is fixed on the top of the support bracket column, and the other end is the cantilever end, and the cantilever end protrudes from the hollow plate at the same plane position;

The upper end surface of the cross beam of the bearing bracket is provided with a bearing bracket chute for horizontal movement of the sliding roller; the sliding roller can move horizontally in the bearing bracket chute; the sliding roller passes through the lifting ring It is connected with the hand-pulled hoist; the hand-pulled hoist is wound with a wire rope; the two ends of the wire rope are connected to the top of the tensioning jack, and the other end of the wire rope goes around the hand-pulled hoist to form a hand-held end.

Corresponding to the sliding rollers, there are triangular wooden blocks for temporarily positioning them.

Limiting plates are respectively provided at both ends of the beam of the bearing bracket.

The multi-directional moving device of the prestressed tensioning jack proposed by the utility model adopts the above technical scheme, utilizes the setting of the bearing bracket, and adjusts the position of the tensioning jack by pulling the wire rope, thereby improving the efficiency of each hollow plate jack. The speed of installation and disassembly improves the efficiency of prestressed tensioning operations.

Detailed ways

The utility model will be described with reference to the accompanying drawings and specific embodiments:

As shown in FIG. 1, a multi-directional moving device of a prestressed tensioning jack, the multi-directional moving device has a bearing bracket base 3 arranged on the hollow plate 14 to be stretched; the bearing bracket base 3 It is arranged on the top of one end of the hollow board 14 to be stretched; the support base 3 is fixed with a support bracket column 4 arranged perpendicular to the hollow plate to be stretched; the top of the support bracket column 4 is fixed with a support bracket. Bracket beam 5; the bearing bracket beam 5 is made of I14 I-beam; one end of the bearing bracket beam 5 is fixed on the top of the bearing bracket pillar 4, and the other end is a cantilever end, and the cantilever The ends protrude from the hollow plate 14 to be stretched at the same plane position; the upper end surface of the bearing bracket beam 5 is provided with a bearing bracket chute 6 for horizontal movement of the sliding roller 7; the bearing bracket The bracket chute 6 is made of 5# channel steel; the sliding roller 7 can move horizontally in the bearing bracket chute 6; the sliding roller 7 is connected with the chain hoist 11 through the lifting ring 10 The wire rope 12 is wound on the hand hoist 11; the two ends of the wire rope 12 are connected to the top of the tensioning jack, and the other end of the wire rope bypasses the manual hoist to form a hand-held end.

Corresponding to the sliding roller, a triangular wooden block 8 is provided for temporarily positioning it.

Limiting plates 9 are respectively provided at both ends of the support bracket beam 5 .

Working principle: First, use the 5t gantry crane of the hollow panel prefabrication factory to hoist the bearing bracket to the end of the top of the hollow panel to be stretched, then connect the upper hook of the 2-ton chain hoist to the lifting ring, and the lower hook of the hand chain hoist, steel wire rope, The chain is connected to the lifting point of the tension jack, and two triangular wooden blocks are placed on the roller chute to temporarily fix the sliding roller. After the jack is returned to the oil and tension is completed, manually loosen the chain down by 2cm vertically. The jack is partially detached from the beam body. Then remove the two triangular wooden blocks that are temporarily limited, and the hand zipper drives the roller to remove the jack from the working length of the tensioned steel strand in the horizontal direction, and then rotate the support bracket to move to the next bundle to be tensioned. Strand.
