Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a special hanger for a butterfly arch bridge. Background Art

[0002] Arch bridges are structures as well as buildings. While bringing people aesthetic enjoyment, they also bring more challenges to the structure. At present, many butterfly arch bridges have been built in China. This elegant bridge type is used in small pedestrian overpasses and large arch bridges of several hundred meters across rivers. However, the complexity and irrationality of its force directly lead to a sharp increase in the cost of the project, and also bring hidden dangers to the safety of the structure. Therefore, when pursuing this beautiful bridge type, the rationality, simplicity and clarity of the force are also taken into account; the existing hangers of this type of bridge are locked with the base. When the hanger is subjected to external force collision and wind action, the force point of the hanger is concentrated in the middle, which will cause shaking, and cause pulling effect on the head and tail ends, causing deformation, and the life will also decrease accordingly. At present, the connection between the hanger and the anchor seat adopts a threaded type. The advantage of the threaded type is that it is easy to disassemble and maintain, and the disadvantage is that the threaded part is easily eroded and rusted by rainwater, resulting in failure of the threaded part, which brings certain adverse effects during use. For this reason, we propose a special hanger for butterfly arch bridges. Summary of the invention

[0003] The main purpose of the present invention is to provide a special hanger for a butterfly arch bridge, which can effectively solve the problems in the background technology.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A special hanger for a butterfly arch bridge comprises a hanger and a hanger seat, wherein an upper connector is arranged at the lower end of the hanger, a lower connector is arranged at the upper end of the hanger seat, a threaded inner sleeve is arranged at the upper end surface of the lower connector, a threaded rod acting on the threaded inner sleeve is arranged in the upper connector, an extrusion groove is opened around the inner wall of the lower connector, a heat transfer oil bag is filled in the extrusion groove, an outer protrusion on the heat transfer oil bag extends out of the hole on the inner wall of the connector, a plurality of groups of the outer protrusions are bonded to the cleaning bag on the inner side, the cleaning bag is composed of sealing rubber and elastic bands alternately connected, and the A dry sponge is provided on the inner side of the sealing rubber, and several groups of tensioning springs are evenly installed on the bottom edge of the upper connector. A corresponding pull ring is provided on the upper edge of the lower connector. The boom seat is movably arranged on the hinge seat, and the hinge seat is installed on the U-shaped base. Connecting forks are symmetrically welded on both sides of the boom seat, and each group of the connecting forks is connected to two groups of hydraulic cylinders. The hydraulic cylinder is arranged on the U-shaped base through an articulated frame. A hose is connected to the bottom of the hydraulic cylinder, and the hose extends into the U-shaped base and is connected to the connecting main pipe. The left and right connecting main pipes are connected to the hydraulic oil kinetic energy pipe group.

[0006] Preferably, the outer wall of the upper connector is provided with a heat-conducting metal layer, and when the outer protrusion expands, the extruded cleaning bag is greatly retracted to wrap the exposed part of the threaded rod and the outside of the threaded inner sleeve.

[0007] Preferably, the tensioning spring device is connected to the pull ring via a hook at the bottom, and the suspension rod seat rotates around the hinge point of the hinge seat.

[0008] Preferably, the hydraulic cylinders are fixedly connected via internal pressure rods and connecting forks, and under normal conditions, the hydraulic cylinders on both sides of the boom seat are in a balanced and symmetrical state.

[0009] Preferably, the hydraulic oil kinetic energy tube group includes a winding capillary oil tube, and a plurality of groups of heat dissipation holes are arranged outside the capillary oil tube.

[0010] The present invention provides a special hanger for butterfly arch bridge by improvement, which has the following significant improvements and advantages compared with the prior art:

[0011] (1) When the sun shines on the upper connector, the heat is concentrated through the heat-conducting metal layer and transferred to the thermal oil bag located in the extrusion groove. The thermal oil bag expands when heated and contracts when cooled. As the temperature rises, its volume increases, acting on several groups of outer protrusions to expand, driving the cleaning bag in the stretched state to retract and slowly wrap around the exposed part of the threaded rod and the outside of the threaded inner sleeve. On the one hand, it plays a wiping and sealing role, and on the other hand, the dry sponge absorbs moisture, thereby maintaining the cleanliness of the exposed part of the threaded rod and preventing rust. Under low temperature conditions, the cleaning bag is pulled back to keep the interior ventilated and breathable.

[0012] (2) When the boom is subjected to wind force or impact force, the boom seat rotates around the hinge point of the hinge seat and cooperates with the buffering effect of the telescopic movement of the hydraulic cylinders on both sides to convert this part of the force into the kinetic energy of the hydraulic oil moving in the capillary oil tube and the heat energy generated by the friction of the tube wall, thereby achieving the effect of transferring the mechanical external force and reducing the overall swing amplitude of the boom, thereby extending the service life of the boom.

[0013] (3) Add several sets of tension springs to the threaded connection part to help share the connection force of the threaded part and reduce the degree of thread wear.

[0014] (4) The entire boom is simple in design and easy to operate, meets actual usage standards, extends service life, and has better results than traditional methods. BRIEF DESCRIPTION OF THE DRAWINGS
