Abstract
The invention provides a hydraulic balance tower crane, which comprises a vertical tower crane frame, a horizontal balance arm, a lifting arm, a base and the like. One end of both the balance arm and the lifting arm is arranged on the tower crane frame; the tower crane frame is provided with a balance detector which mainly comprises a balance pull detector and a lifting pull detector and connected with a balance arm stayed-cable and a lifting arm stayed-cable; and the balance detector is connected with an electrical cabinet through a sensor. The two ends of the balance arm are provided with a liquid storage tank (5) and a liquid storage tank (6) and the two storages tanks on the balance arm are provided with a double-way electric infusion pump in between; and the two storage tanks are connected through two sets of delivery pipes to form a mutual circulating system, so the total weight of the liquid storage tank (5) can change along with the requirement of the balance and finally the whole tower crane reaches the dynamic balance through the hydraulic system. The hydraulic balance tower crane can meet a formula as follows: F(15)=F(16), wherein the formula is that: G(5) X L balance arm=F(15); and G(11) X L lifting arm=F(16) [G(5), G(11) and L balance arm are variables; F(15) is the balance pull; F(16) is the lifting pull; and the weights of the balance arm and the lifting arm are kept constant and skipped.
Description
Technical field
The present invention relates to construction machinery equipment, specifically a kind of hydraulic balance tower crane.
Technical background
Tower crane is one of mechanical equipment that is widely used in the construction trade, because tower crane generally all is to use in skyscraper, belongs to aloft work, and the balance of tower crane is extremely important to keeping the safety in production.Existing tower crane, its balance block is fixing at the not end of equilibrium arm, and be constant motionless, and the weight of the handling thing on the arm, position all change at any time, so tower crane is when work, all the time be in the unbalanced state of relative equilibrium, make the weight of handling thing be subjected to abnormal restriction, especially when tower crane zero load or at full load, unbalance situation is even more serious, accident happens occasionally, and has influenced production efficiency and safety greatly.
Summary of the invention
The objective of the invention is at the deficiency of existing technology and the design-calculated hydraulic balance tower crane, it can realize being association of activity and inertia of tower crane, and balance has all the time improved the safety and the work efficiency of tower crane greatly.
The concrete technical scheme of purpose of the present invention is:
Hydraulic balance tower crane, mainly comprise tower crane frame, equilibrium arm, handling arm, pedestal etc., equilibrium arm, handling arm are located on the tower crane frame, characteristics are that equilibrium arm two ends downside fixedly is equipped with two fluid storage tanks respectively, between two fluid storage tanks the bidirectional electric infusion pump is being housed on the equilibrium arm, is being connected by two cover hydraulic pipes between them.The balance detection instrument is equipped with on the tower crane frame top, and it links to each other with handling arm suspension cable with the equilibrium arm suspension cable respectively, and is connected with electric cabinet by sensor.
In described two fluid storage tanks certain amount of fluid is housed.
Described bidirectional electric infusion pump is wanted the two-way rotation of energy, bidirectional transfusion.
Described balance detection instrument contains balance detection instrument and pulling force detector for being located at the tower crane frame top, and the instrument that can be connected with handling arm suspension cable with the equilibrium arm oblique cord respectively.
The present invention is simple in structure, and is reasonable in design, and the hydraulic balance performance is good, and is easy to operate, improved the job security and the efficient of tower crane greatly.
Description of drawings
See Fig. 1: hydraulic balance tower crane keystone configuration scheme drawing, schematic view illustrating:
(1) tower crane frame (2) equilibrium arm (3) handling arm (4) bidirectional electric infusion pump
(5) fluid storage tank (6) fluid storage tank (7) hydraulic pipe (8) hydraulic pipe
(9) electric cabinet (10) balance detection instrument (11) handling thing (12) pedestal
(13) equilibrium arm suspension cable (14) handling arm suspension cable
(15) balance pulling force detector (16) handling pulling force detector
Specific implementation method:
With reference to hydraulic balance tower crane keystone configuration scheme drawing, the present invention mainly comprises tower crane frame (1), equilibrium arm (2), handling arm (3), pedestal (12) etc., equilibrium arm (2), handling arm (3) are located on the tower crane frame (1), balance detection instrument (10) is equipped with on the tower crane frame top, it mainly is by balance pulling force detector (15) and handling pulling force detector formations such as (16), and be connected with handling arm suspension cable (14) with equilibrium arm suspension cable (13), under the normal circumstances, the pulling force balance of two arms equates, and is connected with electric cabinet (9) by sensor.
Below, equilibrium arm (2) two ends is fixed with fluid storage tank (5) and fluid storage tank (6), certain amount of fluid is arranged in the case, between last two fluid storage tanks of equilibrium arm (2), be provided with bidirectional electric infusion pump (4), and bidirectional electric infusion pump (4) be connected with two fluid storage tanks (5) and (6) by hydraulic pipe (7) and ferry boat hydraulic pipe (8).
Principle of work of the present invention: the weight and the position of going up handling thing (11) when handling arm (3) change, the pulling force on both sides does not wait when unbalance, the balance detection instrument (10) that is located at the tower crane frame top converts detected parameter to electric signal through sensor by balance pulling force detector (15) and handling pulling force detector (16) and delivers to electric cabinet (9), connect the electrical motor forward or reverse allow on the two-way rotation Hydraulic Pump by control circuit, make the liquid in two fluid storage tanks (5) and (6) can import the other side mutually, reach the total weight of fluid storage tank (5) is changed according to the balance needs, thereby make equilibrium arm and handling arm remain the optimum balance state.
The present invention has further improved the balanced capacity of existing tower crane, has reduced the safety misadventure that causes because of unbalance, has increased the safety of work, has improved work efficiency, also is convenient to Assembly ﹠Disassembly.
