Description
Technical field
The utility model relates to mechanical field, and a kind of car hosit packaged type counter weight device is provided especially.
Background technology
At present, the balance weight hanging form that the car hosit of home and abroad adopts all is fixed type or external hanging type, and when using this counter weight device, owing to be subjected to the restriction of car load length and car load total mass, the position of counterweight and weight just limit.The lifting performance of car load and stability are also just determined.But this moment, during lift heavy, the deposit intensity of hoisting crane principal arm was far longer than his working strength, causes the waste of principal arm energy in stability boundary.How under existing situation, improving the counter weight device of car hosit, to increase its lifting performance and whole vehicle stability energy, is the problem that a needs solves.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of car hosit packaged type counter weight device is provided especially; Be to improve the lifting performance of car hosit, increase the whole vehicle stability of car hosit.
The utility model provides a kind of car hosit packaged type counter weight device, it is characterized in that: include rotary table 1, preceding hinge ear 2, preceding bearing pin 3, engine installation 4, rear pin shaft 5, back hinge ear 6, removable counterweight 7, guide piece 8, automatic control device 9; Wherein hydraulic ram spare 4, be connected with preceding bearing pin spare 3 and preceding hinge ear piece 2 and rotary table spare 1, cut with scissors ear piece 6 and removable counterweight 7 is connected with rear pin shaft spare 5 and back, removable counterweight 7 is installed in the guide piece spare 8; Automatic control device 9 is connected with engine installation 4.
Described car hosit packaged type counter weight device, automatic control device 9 adopts the full automaticity limiter of moment, and the hoisting weight during according to real work is controlled the startup operation of engine installation 4.
Described car hosit packaged type counter weight device, engine installation 4 can adopt devices such as hydraulic ram or air cylinder to realize promoting the motion of guide piece 8.
Described car hosit packaged type counter weight device, guide piece 8 adopts mobile chute type structure.
Advantage of the present utility model: by the enforcement of technical solutions of the utility model, greatly improved the lifting performance of car hosit, increased the whole vehicle stability of car hosit.When the car hosit hoisting operation, control by the central control unit of full automaticity limiter of moment, system controls according to the specified lift heavy amount and the principle of the lift heavy value comparison of reality.Conversion compares with rated value afterwards the signal value that comes out according to extraneous sensor measurement through CPU, and when the value of reaching capacity, actual lift heavy amount=specified lift heavy amount will be sent overload prompting and alarm buzzer warning on telltale.At this moment, can start engine installation, promote the packaged type counterweight with hydraulic ram or air cylinder and move, can reach the purpose that improves lifting performance and stability to the hoisting operation opposite sense by automatic or manual.As 35 ° at the principal arm elevation angle, principal arm length 9.8m, work range 7m, but maximum duty is 10 tons of lift heavys during mobile counterweight not, and but 10.5 tons of lift heavys behind the mobile counterweight this shows, the lifting performance that the car hosit of packaged type counter weight device is installed has the raising more than 5%.
