Problems solved by technology

[0005] During the use of the balance weight, it is easy to cause the risk of falling off due to insufficient fixation. At the same time, the balance weight is easy to rotate and shake along the fixed rod under the action of inertia during use, so the balance weight is easy to collide with each other under the action of inertia. To a certain extent There are very serious safety hazards in the

Embodiment 1

[0044] A tower crane counterweight locking device, comprising a balance arm 1, a penetrating slot 3 for placing a counterweight 2 is opened inside the balance arm 1, a fixed rod 4 that extends out movablely is arranged inside the counterweight 2, the fixed rod 4 and the balance The weight 2 is poured and fixed, and the two ends of the fixed rod 4 protrude out of the balance weight 2 respectively. After the fixed rod 4 is completely fixed, the balance weight 2 can be completely fixed. The fixed rod 4 can be set as a cylinder or can be set The rectangular shape needs to be determined according to the actual use situation. The balance arm 1 is located on both sides of the through groove 3 and is fixed with a number of guide rails 5. The inside of the guide rail 5 is equipped with a locking block 6 for fixing the fixed rod 4. The locking block 6 is movable. Set inside the guide rail 5;

[0045] The inside of the locking block 6 is provided with an interconnected baffle groove 7 an...

Embodiment 2

[0049] On the basis of Embodiment 1, considering that cement can solidify faster in a higher temperature environment, this embodiment generates high-temperature gas through the reaction of zinc rod 25 and hydrochloric acid to increase the temperature inside the fixing tank 8, and the bearing block 12 An installation groove 21 and a reaction chamber 22 for storing hydrochloric acid are provided inside, and a bearing plate 23 is movable inside the installation groove 21, and part of the cement and water falling into the fixed groove 8 will fall on the bearing plate 23, and the bearing plate 23 and The inner wall of the installation groove 21 is fixedly connected with a first elastic block 24, and the bearing plate 23 is fixedly connected with a zinc rod 25 that movably extends into the inside of the reaction chamber 22 and is in active contact with the hydrochloric acid. By controlling the surface area of ​​the zinc rod 25 and the concentration of the hydrochloric acid, it can be ...

Embodiment 3

[0051] On the basis of Embodiment 2, considering that if the mixture of cement and water is not stirred, the cement and water cannot be fully fused, the inside of the bearing block 12 is provided with a stirring chamber 26 communicated with the reaction chamber 22, and the inside of the stirring chamber 26 A piston disc 27 is movable, and an elastic rod 2701 is fixedly connected to the inner wall of the piston disc 27 and the stirring chamber 26. The piston disc 27 and the inner wall of the stirring chamber 26 form a closed space, and the gas generated inside the reaction chamber 22 enters the inside of the stirring chamber 26 to drive The piston disc 27 rises, and the piston disc 27 is fixedly connected with a threaded screw mandrel 28 that movably extends into the inside of the fixed groove 8. The threaded screw mandrel 28 passes through the threaded hole 29 and stretches into the inside of the fixed groove 8. The threaded screw mandrel 28 is inside the threaded hole 29. Rota...

Abstract

The invention provides a tower crane balancing weight locking device and a locking method thereof.The tower crane balancing weight locking device comprises a balance arm, a through groove used for containing a balancing weight is formed in the balance arm, a fixing rod movably extending out is arranged in the balancing weight, the balance arm is fixedly provided with a plurality of guide rails, the guide rails are provided with locking blocks, and the locking blocks are arranged in the through groove. A baffle is arranged in the locking block, a bearing block used for bearing the fixing rod is arranged in the fixing groove, a sealing plate movably sealing the fixing groove is arranged in the locking block, and a cement cavity for storing cement is formed in the sealing plate. In the using process, a crane cavity balance weight is used for hoisting, a fixing rod penetrates through a through hole to extend into a fixing groove, a nut is used for fixing a guide rail and a locking block, meanwhile, cement in a cement cavity and water in a water storage cavity fall into the fixing groove in a staged mode, and under cooperation of a stirring assembly and an incandescent lamp, the cement in the cement cavity and the water in the water storage cavity fall into the fixing groove. And the cement and the water are rapidly solidified, and the fixing rod and the locking block are fixed together.

Description

technical field [0001] The invention relates to the technical field of counterweight fixing, in particular to a tower crane counterweight locking device and a locking method thereof. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as tower cranes, which are connected by sections and used to lift construction materials such as steel bars, concrete and steel pipes for construction. The last kind of equipment is indispensable. All upper slewing tower cranes need to be equipped with a balance weight. Its function is to support the balance weight to form the balance moment required by the design in the direction opposite to the lifting moment. [0003] A tower crane counterweight locking device and its locking method provided by the publication number "CN104016251B", including two first twisted wire seats, two second twisted wire seats, first flexible twisted wires and second flexible twisted wires line, two...
