Abstract
The utility model relates to motor driven folding mast, comprising a main mast (3), a movable mast (1) and a folding mechanism; wherein, the folding mechanism comprises an oil cylinder oil cylinder (4) fixed to the main mast (3) and a four-bar linkage mechanism fixed to the main mast (3); besides, the four-bar linkage mechanism is connected with the oil cylinder (4) and the movable mast. A small amount of elements are added to the control system and the hydraulic system, without a large alteration to the original system, because only an all-purpose hydraulic cylinder is added to the spiral digging machine, with the adoption of the project of the utility model, and the cost is a little bit increased. The motor driven fold is adopted, the spiral digging machine can finish the work which originally needs three to five workers to finish, and the labor intensity is reduced, with the increase of efficiency.
Description
Technical field
The utility model has related to the motor-driven folding mast of a kind of mast of building machinery, particularly a kind of Spiral digging machine.
Background technology
In the construction work, bored pile is widely used in various foundation basic constructions field, and the Spiral digging machine construction technology has been represented the advanced level of the world today in the middle of the pouring pile hole construction technology.In order to reduce transportation lengths, the Spiral digging machine mast almost all adopts foldable structure.In the prior art, the folding and expansion of Spiral digging machine mast is that employing is manual, often needs three to five operators to cooperate and just can finish, and labour intensity is big, and efficient is low.
The utility model content
Goal of the invention of the present utility model is the defective that overcomes prior art, and a kind of motor-driven folding mast that can use mechanical handling is provided.
To achieve these goals, a kind of motor-driven folding mast of the present utility model comprises: mainmast, live mast and fold mechanism, wherein: described fold mechanism comprises: be fixed on the mainmast oil cylinder be fixed on mainmast on and the quadric chain that links to each other with live mast with oil cylinder.
Motor-driven folding mast of the present utility model, wherein: described quadric chain is made up of connecting rod AD, AB, DC and BC, connecting rod AD is fixed on the mainmast, and the extended line of connecting rod AB is fixed on the live mast, and the pin joint C of connecting rod BC and connecting rod DC links to each other with an end of oil cylinder.
Motor-driven folding mast of the present utility model, wherein: tie point A, D, B and the C of described connecting rod AD, AB, DC and BC all is hinged.
Motor-driven folding mast of the present utility model, wherein: the other end of described oil cylinder is fixed on the mainmast by jointed shaft.
The utility model is owing to adopted such scheme, Spiral digging machine has only increased a general hydraulic cylinder, so increasing a few components in control system and hydraulic system gets final product, need not original system is done big change, cost increases seldom like this, adopts motor-driven folding simultaneously, originally need three to five work that the operator cooperates and just can finish, only need the operation of Spiral digging machine hand oneself now, greatly improved efficient, reduced labour intensity.
Description of drawings
Fig. 1 is the schematic diagram of the motor-driven folding mast of Spiral digging machine of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of motor-driven folding mast of the present utility model comprises: mainmast 3, live mast 1 and fold mechanism, fold mechanism comprises: be fixed on the mainmast 3 oil cylinder 4 be fixed on mainmast 3 on and the quadric chain 2 that links to each other with live mast 1 with oil cylinder 4, quadric chain 2 is made up of connecting rod AD, AB, DC and BC, connecting rod AD is fixed on the mainmast 3, the extended line of connecting rod AB is fixed on the live mast 1, the pin joint C of connecting rod BC and connecting rod DC links to each other with an end of oil cylinder 4, and the other end of oil cylinder 4 is fixed on the mainmast 3 by jointed shaft 5.Oil cylinder 4 is around jointed shaft 5 swings.Tie point A, D, B and the C of connecting rod AD, AB, DC and BC all is hinged.
When the piston rod of oil cylinder 4 is withdrawn, drivening rod CD rotates around the D point, connecting rod CD forwards the position C ' D of the dotted line of Fig. 1 to, connecting rod BC pulling connecting rod AB rotates around the A point together with live mast 1, connecting rod AB forwards the dotted line position AB ' of Fig. 1 to, live mast 1 has forwarded the dotted line position of figure to thus, has realized folding.In contrast, when the piston rod of oil cylinder 4 stretches out, realize live mast 1 expansion.
