Embodiment 1

[0073] Such as Figure 1~16 As shown, a ship lift balance weight is made of iron-steel sand concrete with high bulk density, and the aggregate is iron ore, including cement, iron ore, iron ore, and water, which are prepared according to the mix ratio;

[0074] The top of the balance weight 1 is provided with lifting lugs 3, and the balance weight 1 is also equipped with a plurality of stoppers 2 embedded with seismic loads. One end of the stoppers 2 is also provided with a fixed plate 4, and the fixed plate 4 protrudes from the balance weight. On the end face of the block 1, the fixed plate 4 is connected with the stop block 2 through a plurality of first locking nuts 5;

[0075] The top or bottom of the balance weight 1 is provided with a steel plate 101 for adjusting the balance weight, and the steel plate 101 is embedded in the bottom or top of the balance weight 1 by screws.

[0076] The concrete balance weight of the ship lift is ultra-large and ultra-thin in structure. ...

Embodiment 2

[0088] Further illustrate in conjunction with embodiment 1, as Figure 1-16 The structure shown includes a pouring platform 6 on which the formwork 11 of the balance weight 1 is arranged, and a plurality of second tensioning screws 18 are arranged between the outer wall of the formwork 11 and the pouring platform 6 . In the manufacture of steel structures and concrete blocks in the hydropower industry, the conventionally used load-bearing platforms are generally steel plate platforms. The steel plate platform is generally a welded assembly of section steel and steel plate, which has poor pressure resistance and deformation resistance. The flatness of the surface of the steel platform is deformed during the manufacturing process of the concrete balance weight, resulting in the dimensional accuracy of the bottom surface of the concrete balance weight not meeting the design requirements. . However, although the solid steel platform can meet the technical requirements, the constr...

Embodiment 3

[0102] Further illustrate in conjunction with embodiment 1 and 2, as Figure 1-16 The structure shown is a method for preparing the balance weight of a ship lift. First, the embedded clamping frame 7 is installed inside the demoulding groove 604 of the pouring platform 6, and the upper surface of the embedded clamping frame 7 and the upper surface of the casting platform 6 are adjusted. flat;

[0103] Reassemble the template: install the template 11 on the embedded wheel I-beam of the pouring platform 6 with the embedded contour line 601, and press the bottom of the template 11 through the embedded bolt 21 and the pressure plate 20, and connect multiple templates 11 with the template 11 Place chamfering strips at the upper and lower ends;

[0104] The upper end of the formwork 11 is tightened by the second tensioning screw 18 between the upper end of the formwork 11 and the fixed groove frame 19, and the upper end of the formwork 11 is fixed, and the formwork 11 is built;

Abstract

The invention provides a ship lift balancing weight and a preparation device and a preparation method thereof, the aggregate is iron ore sand, and the ship lift balancing weight is prepared by blending cement, iron ore, iron ore sand and water according to a mixing ratio; comprising a pouring pedestal, a template of the counterweight block is arranged on the pouring pedestal, and a plurality of second tensioning lead screws are arranged between the outer wall of the template and the pouring pedestal; at least two demolding grooves are further formed in the pouring pedestal, pre-embedded clamping frames are arranged in the demolding grooves, the upper surfaces of the pre-embedded clamping frames are flush with the surface of the pouring pedestal, pushing oil cylinders are further arranged between the two ends of each pre-embedded clamping frame and the corresponding demolding groove, reinforcing steel bars of the internal structure of the ship lift concrete balance weight block are dense, and the requirement for the installation precision of pre-embedded parts is high; meanwhile, the requirement of the product for the concrete pouring quality is extremely high, it is guaranteed that the embedded part cannot generate large displacement in the concrete pouring process, a one-time overall concrete pouring method is adopted, the integrity, the shock resistance and the impermeability of the balance weight block structure are greatly improved, and the concrete balance weight pouring quality is guaranteed.

Description

technical field [0001] The invention relates to the field of ship lift balance weights, in particular to a ship lift balance weight, a preparation device and a preparation method thereof. Background technique [0002] In the overall structure of the lift system of the ship lift, the balance counterweight plays a very important role. The ship lift in the hydropower industry is a navigable structure that uses the method of lifting the box to make the ship overcome the water level drop on the channel, and belongs to a kind of lifting machinery. Among them, the ship-carrying box is the box body part of the ship, and the balance counterweight belongs to the load balancing counterweight in the hoisting machinery, which is specially used to balance the load of the ship-carrying box, reduce the power of the motor, and stabilize the lifting and lowering operation state of the ship-carrying box. The ship-bearing box and the balance weight are connected as a whole by a traction wire r...
