Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a hanging basket steel plate sling height adjustment mechanism. Background Art

[0002] The hanging basket is a crucial piece of equipment in bridge construction, primarily used for cantilever beam casting. This construction method overcomes terrain limitations by dividing the beam into multiple sections and constructing them in sections, ultimately creating a complete beam structure. During construction, the height of the hanging basket needs to be adjusted. Currently, this is done by directly lifting the steel belt and then securing it with a latch. This adjustment method requires re-inserting the latch after each adjustment, which is inconvenient. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a hanging basket steel plate sling height adjustment mechanism.

[0004] The purpose of the utility model is achieved through the following technical solutions: a hanging basket steel plate sling height adjustment mechanism, comprising:

[0005] A lifting mechanism comprising a jack, an upper shoulder beam and a lower shoulder beam, wherein the upper shoulder beam and the lower shoulder beam are respectively arranged at the top and bottom of the jack, and the lower shoulder beam is fixed;

[0006] A steel plate sling assembly includes a sling and a steel belt, the bottom end of the sling is connected to the top end of the steel belt, the bottom end of the steel belt is connected to the hanging basket, the sling passes through the upper shoulder beam and the lower shoulder beam, and the sling is threaded with an upper nut and a lower nut respectively, the upper nut abuts the top of the upper shoulder beam, and the lower nut abuts the top of the lower shoulder beam.

[0007] The utility model connects the top of the steel belt to the suspension rod, and uses the suspension rod to lift the upper shoulder beam through the jack, and the upper shoulder beam abuts the upper nut to lift the suspension rod. After the jack lifts the suspension rod, the lower nut is rotated to make the lower nut abut the lower shoulder beam again, thereby completing the height adjustment of the steel belt and then adjusting the height of the hanging basket, which is convenient and quick.

[0008] In some embodiments, a crossbeam is provided at the bottom of the lower shoulder beam, the length direction of the lower shoulder beam is perpendicular to the length direction of the crossbeam, and the crossbeam is provided on the main truss. By providing the crossbeam, the lower shoulder beam is placed on the main truss.

Channel steels are relatively strong, and the upper and lower shoulder beams formed of two channel steels exhibit relatively high strength.

[0010] In some embodiments, a first pad is provided on each of the upper and lower shoulder beams at positions contacting the jack, and the first pad is fixedly connected to the channel steel. The first pad disperses the force of the jack and transmits it to the two channel steels.

[0011] In some embodiments, a second pad is provided at the location where the top of the upper shoulder beam abuts the upper nut and the location where the top of the lower shoulder beam abuts the lower nut. The second pad is fixedly connected to the channel steel. The second pad increases the contact area between the upper and lower nuts and the channel steel, thereby preventing deformation of the channel steel caused by stress concentration.

[0012] In some embodiments, the slots of the channel steel are provided with reinforcing ribs, which further improve the strength of the upper and lower shoulder beams and prevent deformation.

[0013] In some embodiments, the steel plate sling assembly further comprises a connecting structure for connecting the steel belt to the sling, the connecting structure comprising a connecting plate and a clamping plate assembly;

[0014] The top of the connecting plate is horizontally provided with an end plate, and the bottom end of the suspension rod passes through the end plate. One end of the suspension rod passing through the end plate is threadedly connected to a nut, which is used to abut the end plate and suspend the connecting plate. One end of the clamping plate assembly is connected to the bottom end of the connecting plate, and the other end is connected to the steel belt. The connection plate facilitates the connection between the suspension rod and the steel belt.

[0015] In some embodiments, the clamping plate assembly includes two clamping plates with a gap between the two clamping plates. Pin holes are correspondingly provided on the two clamping plates. Pin holes are provided on the connecting plate and the steel belt. The connecting plate and the steel belt are clamped in the gap between the two clamping plates. The connecting plate and the steel belt are connected to the two clamping plates through pin holes and pin shafts. The connecting plate and the steel belt are connected through the two clamping plates.

[0016] The utility model has the following advantages:

[0017] The utility model sets the top of the steel plate sling as a suspension rod, and the upper nut and the lower nut are connected by threads on the suspension rod. The suspension rod is raised by lifting the upper nut with a jack. After the suspension rod is raised, the lower nut leaves the lower shoulder beam, and the lower nut is rotated to make the lower nut contact with the lower shoulder beam again, thereby completing the height adjustment of the steel belt. The utility model is convenient and quick, and there is no need to re-insert or remove the pin during the adjustment process. BRIEF DESCRIPTION OF THE DRAWINGS
