Description

Technical Field

[0001] The utility model relates to the technical field of bridge frame installation, in particular to a bridge frame hoisting structure. Background Art

[0002] Electrical design refers to the planning and design of electrical systems in construction, power, and other engineering projects. It encompasses the selection, configuration, and installation of electrical equipment and wiring, including lighting, power supply, low-voltage distribution, control systems, and grounding systems. Cable trays are commonly used in electrical design to support and protect cables. These cables are typically made of metal or plastic and are widely used in industry, power generation, construction, and other fields.

[0003] Hoisting is the most common way to install a bridge. Existing hoisting devices usually include a hanger and a hanger frame. The hanger is used to support the vertical part of the bridge and is usually made of high-strength steel. The hanger is fixed to the floor or support beam by bolts or welding; the hanger frame is used as a horizontal support for the hoisting bridge, which can effectively share the weight of the bridge and maintain stability. The hanger frame is connected to the hanger through connectors (such as nuts and bolts) to ensure a tight connection.

[0004] However, the existing lifting device still has the following shortcomings during use:

[0005] During the hoisting and installation process of the bridge, there is a need to arrange the bridge at an angle, but the existing hanging frame is usually formed in one piece, and it is difficult to adjust the working support angle of the hanging frame after connecting it to the suspension rod, and its practicality needs to be improved.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1:

[0033] See also Figures 1 to 3 In an embodiment of the present invention, a bridge hoisting structure includes a hanging frame and a threaded hanging rod 3. The hanging frame includes a mounting plate 1. Both ends of the bottom surface of the mounting plate 1 are fixedly connected to a hanging plate 2. A connecting component used in conjunction with the threaded hanging rod 3 is fixedly installed on the outer surface of the hanging plate 2 near the top.

[0034] A mounting groove 13 is provided on the outer surface of the hanging plate 2 near the bottom. A supporting mechanism is installed between the bottoms of the two hanging plates 2. The supporting mechanism includes a supporting assembly and a locking assembly.

[0035] The support assembly is rotatably mounted between the two hanging plates 2, and both ends of the support assembly extend into the two mounting slots 13 respectively;

[0036] The locking assembly is disposed between the two mounting slots 13 , and is used to limit the relative rotation between the supporting assembly and the hanging plate 2 .

[0037] The support assembly includes a mounting shaft 7, which is rotatably mounted between the two hanger plates 2. The end of the mounting shaft 7 rotates through the inner side of the corresponding hanger plate 2 to the mounting groove 13, and the end of the mounting shaft 7 is coaxially fixed with a gear 15 located in the mounting groove 13.

[0038] Two symmetrically distributed protrusions 8 are fixedly mounted on the periphery of the installation shaft 7 , and a support plate 6 for supporting the bridge is fixedly connected between the ends of the two protrusions 8 away from the installation shaft 7 .

[0039] The locking assembly includes a connecting plate 9 provided below the two hanging plates 2, with slide bars 12 fixedly connected to both ends of the top surface of the connecting plate 9. The top ends of the two slide bars 12 slide through the bottom surfaces of the corresponding hanging plates 2 to the corresponding mounting grooves 13, and are fixedly connected to racks 14 located in the mounting grooves 13. The two ends of the racks 14 are in self-sliding contact with the side walls of the mounting grooves 13.

[0040] The outer periphery of the slide rod 12 is provided with a spring 11 located between the bottom surface of the hanging plate 2 and the top surface of the connecting plate 9, and the two ends of the spring 11 are fixedly connected to the hanging plate 2 and the connecting plate 9 respectively. Under the elastic force of the spring 11, the rack 14 and the gear 15 are squeezed and contacted;

[0041] A handle 10 is fixedly mounted on the bottom surface of the connecting plate 9 .

[0042] Among them, the connecting component includes a boss 4 fixedly installed on the outer surface of the hanging plate 2, a threaded hanger 3 is slidably installed on the top surface of the boss 4, and a nut 5 located below the boss 4 is installed on the outer thread of the threaded hanger 3.

[0043] When the utility model is in use:

[0044] Fix the top ends of the two threaded hangers 3 at the preset positions, then connect the hanging frame and the threaded hangers 3 through the bosses 4 and nuts 5. The height of the hanging frame can be adjusted by adjusting the positions of the nuts 5 on the threaded hangers 3. When supporting the bridge, pass the bridge between the mounting plate 1 and the support plate 6, and the support plate 6 supports the bridge.

[0045] When the bridge needs to be tilted, the staff can pull down the connecting plate 9 through the handle 10, so that the two slide bars 12 drive the two racks 14 to separate from the two gears 15. At this time, the installation shaft 7 and the two hanging plates 2 are allowed to rotate, and the angle of 6 can be changed according to the inclination of the bridge, so that the contact surface of the support plate 6 and the bridge remains parallel. After the adjustment, the handle 10 is released. At this time, under the restoring elastic force of the spring 11, the two racks 14 are reset in the installation groove 13 to a state of extrusion and meshing with the gears 15, thereby limiting the rotation of the installation shaft 7 and keeping the support plate 6 in a stable supporting working state.

[0046] Therefore, in the present invention, the bottom of the hanging frame can be flexibly adjusted in angle through the coordination of the mounting plate 1, the hanging plate 2, and the supporting assembly and the locking assembly in the supporting mechanism, so as to meet the demand for rapid adjustment of the bridge frame when it needs to be arranged at an angle. The adjustment design makes the installation process simpler, and workers can install and maintain it more conveniently, thereby improving work efficiency.

[0047] Example 2:

[0048] See also Figure 4 and Figure 5 On the basis of Example 1, a stabilizing component for pressing the bridge frame onto the support plate 6 is provided on the mounting plate 1, and the stabilizing component includes a threaded rod 16, the bottom end of the threaded rod 16 is threaded through the mounting plate 1 at the center position of the top surface of the mounting plate 1, and the bottom end of the threaded rod 16 is rotatably connected to a U-shaped mounting seat 18, a pin shaft 21 is fixedly connected between the two sides of the U-shaped mounting seat 18, a connecting block 20 is fixedly connected to the periphery of the pin shaft 21, and a pressure plate 19 is fixedly connected to the end of the connecting block 20 away from the pin shaft 21; a knob 17 is fixedly installed on the top of the threaded rod 16.

[0049] By rotating the threaded rod 16 through the knob 17, the pressure plate 19 can be driven down, thereby pressing the bridge frame against the support plate 6, which can effectively prevent the bridge frame from sliding or falling off during use, ensuring the safety of cables and lines and reducing the risk of accidents.

[0050] Among them, through the arrangement of the U-shaped mounting seat 18, the pin shaft 21 and the connecting block 20, the pressing plate 19 can remain parallel to the contact surface of the bridge after the bridge is pressed, thereby improving the stability of the pressed state.
