Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a suspended hoop installation operation platform. Background Art

[0002] During the construction of a bridge, the construction of the middle beam and capping beam of a cylindrical pier adopts the method of using a hoop support. Installing the hoop on the upper end of the bridge column is an important construction process. There are two existing installation methods. One is to use a crane to lift the construction platform to the upper end of the column, and the operators work on the construction platform to install the hoop. This method not only requires large machinery such as a crane, but also requires an open construction site. Moreover, it is necessary to move the construction platform to both sides of the bridge column through the crane for construction, resulting in low construction efficiency. Content of the Utility Model

[0003] The utility model aims to provide a suspended hoop installation operation platform with the bridge column as the carrier of the construction platform, which solves the problem of low efficiency when the existing crane is used as the carrier of the construction platform to fix the hoop.

[0004] To achieve the above purpose, the utility model adopts the following technology: a suspended hoop installation operation platform, characterized in that it includes a platform body and a suspension structure. The suspension structure is supported on the upper end surface of the bridge column to suspend the platform body. The platform body is sleeved on the upper end of the bridge column. The platform body includes a chassis and a side fence surrounding the periphery of the chassis. The chassis is provided with a central hole for the bridge column to pass through.

[0005] Preferably, the hoop includes two hoop halves. The two ends of the two hoop halves are connected together in one-to-one correspondence through two hoop connection structures. The hoop connection structures are located on the periphery of the space enclosed by the two hoop halves. The diameter of the central hole is larger than the outer diameter of the ring enclosed by the two hoop halves. Two avoidance notches are provided on the peripheral wall of the central hole for the two hoop connection structures to pass through in one-to-one correspondence. In the second step, the hoop can be lifted and surrounded the lower end of the bridge column. The two hoop connection structures on the hoop are aligned with the two avoidance notches. The construction workers pull up the hoop so that the hoop passes through between the chassis and the bridge column and reaches the upper end of the bridge column, and then install it according to the upper end of the bridge column.

[0006] Preferably, a plurality of blocking rods distributed circumferentially around the central hole are hinged to the central hole. The blocking rods are used to block the gap between the chassis and the bridge column. When the blocking rods are moved upward, the blocking rods can rotate about the hinge axis to open the gap. When the blocking rods are moved downward, the blocking rods can maintain the blocking in the gap. When the hoop passes through the gap, it hits the blocking rods to open the blocking rods. When the hoop moves above the blocking rods, the blocking rods swing downward under the action of their own weight and reset to block the gap again.

[0007] Preferably, a support roller is provided at one end of the blocking rod facing the center of the central hole, which supports on the bridge column when the blocking rod moves towards the bridge column.

[0008] Preferably, one end of the blocking rod is connected to a cable. The other end of the cable bypasses a fixed pulley and passes through a rope-passing hole on the chassis from top to bottom and reaches above the chassis. The cable is provided with a pin hole and a chuck. When the pin passes through the pin hole and is stuck at the upper end of the rope-passing hole, the blocking rod maintains the blocking in the gap. When the chuck is stuck at the upper end of the rope-passing hole, the blocking rod can swing upward to a position where it loses the blocking effect on the gap.

[0009] Preferably, a passage for entering the chassis is provided on the fence, and a blocking door is connected to the passage in an openable and closable manner. During construction, construction workers can enter the chassis through the passage.

[0010] Preferably, the suspension structure includes two cross-shaped beams, and both ends of the beams are connected to the platform body through suspension rods.

[0011] Preferably, the suspension rods are connected to the chassis, and the side fence is connected to the suspension rods.

[0012] Preferably, it further includes an upper friction cable sleeved on the bridge column and a lower friction cable sleeved on the bridge column. The suspension structure is detachably connected to the platform body. One end of the upper friction cable is provided with an upper through-hole, and the other end passes through the through-hole and is connected to the upper rope loop. One end of the upper pulling rope is fixed to the platform body, and the other end passes through the upper rope loop and is connected to the upper pulling rope winding disc. The upper pulling rope winding disc is connected to the upper pulling rope winding motor, and the upper pulling rope winding motor is fixed on the platform body. One end of the lower friction cable is provided with a lower through-hole, and the other end passes through the lower through-hole and is connected to the lower rope loop. One end of the lower pulling rope is fixed to the platform body, and the other end passes through the lower rope loop and is connected to the lower pulling rope winding disc. The lower pulling rope winding disc is connected to the lower pulling rope winding motor, and the lower pulling rope winding motor is fixed on the platform body. The specific process of removing the suspended hoop installation operation platform is as follows: First step, make the lower friction cable in a state where it can descend together with the platform body, tie the upper friction cable tightly to the bridge column, drive the upper pulling rope winding disc to rotate through the upper pulling rope winding motor, and stop when the upper pulling rope winding disc rotates until the upper pulling rope is wound to a tensioned state, so that the upper friction cable is maintained in a state of being tied tightly to the bridge column, and remove the suspension structure from the bridge column so that the platform body is suspended on the upper friction cable tied to the bridge column by the upper pulling rope. Second step, drive the upper pulling rope winding disc to rotate through the upper pulling rope winding motor. The result of the rotation of the upper pulling rope winding disc is to make the upper pulling rope unwind from the upper pulling rope winding disc, so that the platform body is suspended by the upper pulling rope and moves down a set distance. Third step, tie the lower friction cable tightly to the bridge column, drive the lower pulling rope winding disc to rotate through the lower pulling rope winding motor, and stop when the lower pulling rope winding disc rotates until the lower pulling rope is wound to a tensioned state, so that the lower friction cable is maintained in a state of being tied tightly to the bridge column. Fourth step, drive the upper pulling rope winding disc through the upper pulling rope winding motor to make the upper pulling rope unwind from the lower pulling rope winding disc, and the upper friction cable becomes loose. After the upper friction cable becomes loose, it falls along the bridge column to above the lower friction cable, and the platform body is suspended on the lower friction cable tied to the bridge column by the lower pulling rope. Fifth step, tie the upper friction cable tightly to the bridge column, drive the upper pulling rope winding disc to rotate through the upper pulling rope winding motor, and stop when the upper pulling rope winding disc rotates until the upper pulling rope is wound to a tensioned state, so that the upper friction cable is maintained in a state of being tied tightly to the bridge column. Sixth step, drive the lower pulling rope winding disc to rotate through the lower pulling rope winding motor. The result of the rotation of the lower pulling rope winding disc is to make the lower pulling rope unwind from the upper pulling rope winding disc and loosen the lower friction cable from the bridge column, so that the platform body is suspended by the upper pulling rope. Seventh step, drive the upper pulling rope winding disc through the upper pulling rope winding motor to make the upper pulling rope unwind from the upper pulling rope winding disc, so that the platform body is suspended by the upper pulling rope and moves down a set distance. Repeat the third step to the seventh step until the platform body moves down to the ground.

[0013] Preferably, the upper friction cable includes a head section, a spring piece with one end connected to one end of the head section, and a tail section with one end connected to the other end of the spring piece. The upper through hole is provided at the other end of the head section, and the upper rope loop is connected to the other end of the tail section. After the pulling rope is released, the upper friction cable can be released from the bridge column under the elastic force of the spring piece, so that it is convenient to release the upper friction cable at a high altitude bound to the bridge column.

[0014] Beneficial effects: It can fix and hang the hoop installation operation platform with the bridge column as the carrier, so that there is no need for an open site when fixing the construction platform, and the bridge column will not be smoothed. Description of the Drawings
