Description

Anchoring device for air shield dam

Technical Field

The utility model belongs to the technical field of air shield dams, and in particular relates to an air shield dam anchoring device.

Background Art

The shield plate of the air shield dam is connected to the base plate, and an air bag is set at the angle. By inflating and exhausting the air bag, the dam can be raised and lowered. The connection between the shield plate and the base plate, and the connection between the air bag and the base plate are anchored by pre-embedded bolts or prefabricated cement blocks. During long-term work, maintenance problems are likely to occur at the soft connection of the shield plate or the air bag. When the embedded anchors are repeatedly disassembled, they are prone to loosening and damage, thereby damaging the base plate.

The prior art provides an air shield dam anchoring device as shown in FIG1 , which mainly realizes connection with the pressure block assembly by pre-embedded connecting blocks in the installation foundation to avoid damage to the installation foundation due to frequent disassembly and assembly. However, the obvious defect of this structure is that it is cast once and has a limited service life. After multiple disassembly and assembly and maintenance, it needs to be damaged and re-cast, which increases the maintenance workload and costs.

Utility Model Content

The utility model aims to avoid damage to the installation base when the connection block is disassembled and assembled, and at the same time to increase the service life of the connection block or reduce the cost and workload during reconfiguration.

The technical solution adopted by the utility model is an air shield dam anchoring device, including an upper pressure plate, a lower pressure plate, and an underground block, the underground block is composed of a main body extending along the length direction and a plurality of movable struts uniformly arranged on both sides of the main body along the length direction;

The inner end of the movable support rod is movably connected to the main body through a pin shaft, so that the outer end of the movable support rod is rotated outwardly by 90 degrees around the pin shaft and is placed perpendicular to the main body.

As a further improvement, a coaxial screw hole is provided at the central portion of the upper pressing plate and at one end of the lower pressing plate, and a bolt passes through the screw hole from top to bottom and is threadedly connected with the screw hole on the main body.

The utility model has the following beneficial effects: the damage to the installation foundation is effectively avoided; the disassembly and assembly and maintenance of the connection block are simple; the construction amount is small and the cost is low.

DETAILED DESCRIPTION

The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In the description of the present invention, it should be understood that the terms "center, lateral, longitudinal, up, down, front, back, left, right, vertical, horizontal, top, bottom, inside, outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in FIG. 2 , and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

At present, the shield plate or airbag of the gas shield dam is provided with a soft connection at the connection with the foundation bottom plate, and the connection method is to connect with the foundation bottom plate through a pre-buried anchor bolt, or to set an internal thread on the foundation bottom plate, and then pass the bolt through the soft connection to connect with the internal thread of the foundation bottom plate. The structural schematic diagram of the existing first connection method is shown in Figure 1. The anchor bolt is first pre-buried on the foundation bottom plate, and the anchor bolt connection head is exposed on the foundation bottom plate. The shield plate or airbag soft connection passes through the anchor bolt and is then fixed by a nut. At present, the anchor bolt is pre-buried on the foundation bottom plate, and the anchor bolt is only fixed by the cement of the foundation bottom plate. Its stability is poor. When the shield plate or airbag needs to be maintained, the nut and anchor bolt need to be repeatedly disassembled, which is easy to loosen the pre-buried anchor bolt or damage the foundation bottom plate.

In order to avoid damage to the installation base when the connecting block is disassembled and assembled, and to increase the service life of the connecting block or reduce the cost and workload during reconfiguration, the present embodiment provides an air shield dam anchoring device as shown in FIG. 3, including an upper pressure plate 1 and a lower pressure plate 2 placed above the installation base 7 as shown in FIG. 2, and also including a buried block 3 placed in a mounting groove 8 in the installation base 7, the buried block 3 is composed of a main body 4 extending along the length direction of the mounting groove 8 as shown in FIG. 3 or 4, and a plurality of movable struts 5 uniformly arranged on both sides of the main body 4 along the length direction; the inner end of the movable strut 5 is movably connected to the main body 4 through a pin shaft, so that the outer end of the movable strut 5 is rotated outward 90° around the pin shaft and is placed perpendicular to the main body 4. As shown in FIG. 2 It can be seen that when the movable support rod 5 is rotated to the vertical position of the main body 4, it is just clamped in the mounting cavity 9 on the side wall of the mounting groove 8, thereby realizing the limitation of the main body 4, and the buried block 3 is clamped in the mounting groove 8, and then with the help of the central part of the upper pressure plate 1 and one end of the lower pressure plate 2 shown in Figure 2, a coaxial screw hole is respectively provided, and a bolt 6 passes through the screw hole from top to bottom and is threadedly connected with the screw hole on the main body 4, that is, the upper pressure plate 1 and the lower pressure plate 2 are fixed to the main body 4 of the buried block 3 by the bolt 6, thereby realizing the fixation of the soft connector of the shield plate of the air shield dam, and completing the fixation of the shield plate. During the later maintenance or disassembly and assembly, it is only necessary to realize the fixed connection with the buried block, and the entire disassembly and assembly process will not cause damage to the installation base 7.

When the buried block 3 needs to be replaced or repaired, local repair or overall replacement is adopted according to the damage condition, and the installation foundation 7 will not be damaged during the entire maintenance process. In particular, the replacement of the buried block is very simple and can be completed by lifting with lifting equipment, with small construction volume and short time, which greatly saves maintenance costs.
