Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0031] Best practice: eg figure 1 , 2 As shown, a system for remotely hanging movable counterweights on a railway crane includes a turntable A and a movable counterweight 1 with lifting lugs 1-1. Wherein, the structure diagram of the movable counterweight 1 with lifting lug 1-1 is as follows: Figure 4 shown.

[0032] The turntable A is fixedly provided with a lifting mechanism 4 with a hook 3 at the bottom, the hook 3 is provided with a locking pin hole 2 3-1, and the top of the hook 3 is provided with a connecting pin hole 3-2, and the structure is as follows: Image 6 , 7 shown.

[0033] The turntable A is also provided with a locking mechanism 6 with a locking pin 6-1. When the locking pin 6-1 stretches out horizontally, it can pass through the locking pin hole 2 3-1 on the hook 3 to lock. The locked state is as follows: image 3 shown.

[0034] In this embodiment,...

Abstract

The invention discloses a system for remotely controlling a movable counterweight to be hung on a railway crane. The system comprises a rotating table and the movable counterweight with lifting lugs. A lifting mechanism with a hook at the bottom is fixedly arranged on the rotating table. The hook is provided with a second locking pin hole. A locking mechanism with a locking pin is arranged on the rotating table. The locking pin can penetrate through the second locking pin hole in the hook when horizontally extending out. The lifting mechanism and the locking mechanism are respectively connected with an electric control table through a hoisting solenoid valve and a locking solenoid valve. The system has the advantages of being capable of remotely controlling the movable counterweight to be hung, so that the hoisting capacity of the crane is greatly improved. Moreover, the system has the advantages that the movable counterweight can be hung conveniently, working efficiency is high, labor intensity is low, safety is high, manufacture cost is low, and economical efficiency is good.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a system for remotely hanging movable counterweights on railway cranes. Background technique [0002] The telescopic boom railway cranes produced by domestic manufacturers include NS1001, NS1601, NS1602, NS1251, NS1252, etc. The movable counterweights of these cranes are all hung and placed by hydraulic manual valves to control oil cylinders and push them manually. The way the activity is weighted. The disadvantages of this manual method are: because the movable counterweight has 20-30t, the diameter of the two fixed movable counterweight pins is φ40-φ50mm, and the length is about 1000mm. The upper fixing seat is fixed, and the labor intensity is relatively large, and it is difficult to align with the hole of the fixing seat on the turntable, and accidents are also easy to occur. [0003] Telescopic boom railway cranes produced abroad, such as Germany's KIROW, use telescopic cou...
