Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction equipment, in particular to a self-propelled diamond truss hanging basket for suspended pouring construction of a large-span bridge. Background Art

[0002] The development of science and technology has greatly promoted the progress of bridge design and construction. Among them, prestressed concrete continuous beams and continuous steel beams are the most commonly used bridge forms. Prestressed concrete continuous beams and continuous steel beams generally have large spans and cross rivers and valleys, so cantilever beam casting construction is mainly adopted. Now continuous beams mostly adopt single-box double-chamber or single-box multi-chamber. The bridge deck is wide and the segment weight is heavy. The entire segment is required to be cast in one time, which puts higher requirements on the cantilever casting method. In order to process one end of the bridge, the diamond truss hanging basket will be extended to one end of the bridge, which is convenient for the staff to stand on the diamond truss hanging basket, and then it is convenient to carry out construction during the bridge processing.

[0003] During the installation and use of the diamond truss hanging basket, a track will be installed on the bridge, and the track will drive the diamond truss hanging basket to move to one end of the bridge. At the same time, in order to facilitate the staff to process one end of the bridge, the processing area is usually set at one end of the bridge. At the same time, the diamond truss hanging basket uses the diamond structure to turn the processing area to one side. In order to ensure the stability of the frame, the frame structure is usually made of steel structure, which makes the overall mass of the processing area frame large. When the track drives the diamond truss hanging basket to move to one side, the gravity on the side where the diamond truss hanging basket is connected to the track will increase. When the gravity increases, the friction between one end of the diamond truss hanging basket and the track will increase, which will affect the sliding efficiency of the hanging basket on the track. For this reason, we proposed a self-propelled diamond truss hanging basket for suspended pouring construction of large-span bridges. Utility Model Content

[0004] In view of the shortcomings of the existing self-propelled diamond truss hanging basket for suspended pouring construction of large-span bridges, the utility model provides a self-propelled diamond truss hanging basket for suspended pouring construction of large-span bridges, which is equipped with a starting hydraulic rod to adjust the angle of the diamond truss. At the same time, the diamond truss drives the vertical rod to move to the side of the slide rod. By adjusting the position of the vertical rod, the center of gravity of the entire equipment on the upper end of the installation sleeve can be driven to remain in a centered state, avoiding the advantage of increased friction due to unstable center of gravity, thereby solving the problems raised in the above-mentioned background technology.

[0006] Preferably, a limiting plate is installed on the side of the limiting sleeve, and the mounting sleeve is sleeved on the outside of the limiting plate, and positioning holes are provided at equal intervals at the connection between the limiting plate and the mounting sleeve.

[0007] Preferably, the reinforcement sleeve is sleeved on the lower part of the bridge section, and the roller is fittedly installed on the lower end of the bridge section.

[0009] Preferably, the first mounting plate is sleeved on the outside of the two groups of vertical rods, and the first mounting plate is arranged on the side of the bridge section.

[0010] Preferably, the second mounting plate is installed on both the upper end and the lower end of the first mounting plate, and the second mounting plate is installed on one side of the bridge section.

[0011] Preferably, the positioning plate is arranged on the upper part of the second mounting plate, a slide groove is opened in the middle part of the second mounting plate, and the slide groove is arranged between the threaded rod and the fastening bolt.

[0012] Compared with the existing self-propelled diamond truss hanging basket for long-span bridge suspended pouring construction, the utility model has the following beneficial effects:

[0013] 1. The self-propelled diamond truss hanging basket for the suspended pouring construction of the large-span bridge is constructed by removing the second mounting plate from the inside of the first mounting plate and starting the hydraulic rod at the same time. The hydraulic rod grows and the inner angle of the diamond truss moves to 90 degrees, driving the vertical rod to move to both sides of the mounting sleeve. At the same time, the overall center of gravity of the truss hanging basket remains stable, and the hydraulic device is used to push the slide rod to move on the upper part of the slide rail to avoid one end of the slide rod being pressed down due to gravity, which in turn causes an increase in friction between the front end of the slide rod and the slide rail, affecting the movement efficiency of the slide rod inside the slide rail.

[0014] 2. The self-propelled diamond truss hanging basket for the suspended pouring construction of the large-span bridge is sleeved on the inside of the vertical rod through the first mounting plate, so that the first mounting plate and the second mounting plate can be easily disassembled and replaced, and the position of the threaded rod inside the second mounting plate is adjusted at the same time. The threaded rod is arranged on the upper part of the second mounting plate, and the fastening bolts are rotated. The threaded rod and the fastening bolts squeeze and limit the position of the second mounting plate, thereby improving the stability of the second mounting plate when the position is limited.

A reinforcement sleeve 6 is fixedly connected, and a roller 7 is movably sleeved inside the lower end of the reinforcement sleeve 6. The reinforcement sleeve 6 is sleeved on the outside of the bridge section 1 to improve the stability of the reinforcement sleeve 6 when sliding on the outside of the bridge section 1. Hydraulic rods 9 are installed on the outside of the diagonal parts of the diamond truss 8. The hydraulic rods 9 adjust the inclination angle of the diamond truss 8.

The first mounting plate 12 is arranged on the outside of the vertical rods 11, and the first mounting plate 12 is installed on both sides of the bridge section 1. When the second mounting plate 13 is removed from the inside of the first mounting plate 12, the first mounting plate 12 can be moved to the side of the bridge section 1, thereby avoiding the second mounting plate 13 interfering with the movement of the first mounting plate 12 when the first mounting plate 12 moves to both sides of the slide rod 3.

At the same time, when the slide rod 3 moves to one end of the slide rail 2, adjust the angle of the diamond truss 8, and the diamond truss 8 drives the connecting plate 10 to extend to the bridge. The side of the beam section 1, and the second mounting plate 13 is sleeved inside the first mounting plate 12. The first mounting plate 12 and the second mounting plate 13 can extend to the side of the bridge section 1, and one side of the bridge section 1 can be processed inside the first mounting plate 12 and the second mounting plate 13.
