The utility model has the advantages that the goal of balancing the hanging arm is realized through changing the water volume in the weight balancing water tank in real time, the tower body only bears the vertical pressure, and the folding force caused by laterality is eliminated, so the hoisting weight of the tower crane is greatly increased.
Description
Technical field
The utility model relates to the vehicle for construction technical field, is specifically related to a kind of tower crane.
Background technology
At present, traditional tower crane is by tower body, arm, equilibrium arm, compositions such as concrete weight coating piece.Its clump weight has been a balance laying particular stress on of arm can produce again when slinging weight and lay particular stress on, and laying particular stress at this moment relies on the intensity of tower body self to overcome, and the resistance to bending of tower body self is limited, and this has just limited the lifting amount greatly, thereby has limited work efficiency.
The utility model content
In order to address the above problem, the tower crane that provides a kind of amount of lifting bigger is provided the purpose of this utility model.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of tower crane, comprise a tower body, be provided with an arm and an equilibrium arm in the left and right sides, described tower body top, be equipped with a suspension hook at the arm end, be provided with a counterweight water tank at described equilibrium arm end, tower body top be positioned at arm and equilibrium arm below be provided with a regulating tank, described counterweight water tank is connected by water pipe with regulating tank, respectively is provided with a water pump in counterweight water tank and regulating tank.
In order to make tower itself keep vertical and balance, described regulating tank is around being arranged on tower body top.
In order to cushion lifting and to put down exchanged water certain hour between weight and the feed-tank, described suspension hook is the buffering suspension hook, and described buffering suspension hook is made of the spring housing width of cloth.
In order to realize the counterweight automatic guidance, on the pump switch circuit, be connected with a sensor and an electrical controller, described sensor is used to respond to the weight of object that arm lifts by crane, the object of the lifting of the water that described electrical controller is used for realizing the counterweight water tank according to the numerical value of sensor sensing with the action of control water pump on just can the balance crane arm.
For the ease of the water yield of control in the water tank, the volume of described counterweight water tank when equaling the specified biggest lifting capacity of crane loading, is the water capacity of the required counterweight of balance arm.
For the ease of the water yield of control in the water tank, the volume of described regulating tank, the volume that equals the counterweight water tank deduct poor in order to the water capacity of the empty arm of balance.
The utility model, to realize the purpose of balance arm, described tower body only bears vertical pressure, has eliminated the folding power that produces because of laying particular stress on by water capacity in the real time altering counterweight water tank, makes that lifting weight of the present utility model has obtained improving greatly.
The utility model not only provides lifting weight greatly, and has saved heavy concrete weight coating.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is a structural representation of the present utility model.

The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
As shown in Figure 1, the utility model discloses a kind of tower crane, comprise tower body 1, be provided with arm 2 and equilibrium arm 3 in the left and right sides, tower body 1 top, be equipped with a suspension hook 4 at arm 2 ends, suspension hook 4 is the buffering suspension hook, and it is made of the spring housing width of cloth, is used to cushion lifting or puts down lifting thing 11 act on time on the arm 2; Be provided with counterweight water tank 5 at equilibrium arm 3 ends, it is used to replace original clump weight with balance arm 2; Be provided with regulating tank 6 below tower body 1 top is positioned at arm 2 and equilibrium arm 3, described counterweight water tank 5 is connected by water pipe 7 with regulating tank 6, respectively is provided with a water pump 8 in counterweight water tank 5 and regulating tank 6;
When crane arm lifts by crane the lifting thing of Different Weight, the counterweight difference of required counterweight water tank so just need increase the weight of or loss of weight to counterweight water tank 5, promptly injects water or takes water away to the counterweight water tank, therefore, with counterweight water tank 5 bonded assembly regulating tanks 6 with regard to particular importance.
As shown in Figure 1, regulating tank 6 is around being arranged on tower body 1 top, and regulating tank 6 is arranged at herein, and is both very near apart from counterweight water tank 5, makes in two water tanks reaction time of water exchange to accelerate, and can avoid tower body 1 to occur laying particular stress on again.
As shown in Figure 1, for the volume of water in the automatically regulating counterweight water tank to suitable degree, on the pump switch circuit, be connected with a sensor 9 and an electrical controller 10, described sensor 9 is used to respond to the weight of arm 2 object that lifts by crane, the object of the lifting of the water that described electrical controller 10 is used for realizing counterweight water tank 5 according to the numerical value of sensor 9 induction with the action of control water pump 8 on just can balance crane arm 2.
The volume of counterweight water tank when equaling the specified biggest lifting capacity of crane loading, is the water capacity of the required counterweight of balance arm; The volume of described regulating tank, the volume that equals the counterweight water tank deduct poor in order to the water capacity of the empty arm of balance.When practical operation, be easy to allocation ratio so, calculate the volume of counterweight water tank and the volume of regulating tank according to empty arm and specified maximum lifting, arm and equilibrium arm.When adding water so for the first time, just can under the situation of empty arm, directly fill it up with the counterweight water tank, get final product in that the water in the counterweight water tank is injected and fills with regulating tank then.Therefore, the setting of this kind volume is convenient to add for the first time water or is proofreaied and correct water in the water tank.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and field of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
