Abstract
The utility model discloses a foldable hoisting arm structure of a lorry-mounted crane. The foldable hoisting arm structure comprises an upright post, a basic arm and a main arm; the basic arm is connected with the upright post; a transitional arm is arranged between the basic arm and the main arm; a rear folding link mechanism and a rear amplitude variation hydrocylinder are arranged between the upright post and the basic arm, wherein the rear amplitude variation hydrocylinder acts on the rear folding link mechanism; and a front folding link mechanism and a front amplitude variation hydrocylinder are arranged between the basic arm and the transitional arm, wherein the front amplitude variation hydrocylinder acts on the front folding link mechanism. According to the foldable hoisting arm structure of the lorry-mounted crane, the folding link mechanisms are additionally arranged on a hoisting arm; the front folding link mechanism and the rear folding link mechanism are controlled by the amplitude variation hydrocylinder; and during the process of hoisting or transporting, the process of hoisting arm folding is achieved by a way that the folding scales of the front folding link mechanism and the rear folding link mechanism are controlled by the front amplitude variation hydrocylinder and the rear amplitude variation hydrocylinder when the crane is required for being folded. The foldable hoisting arm structure of the lorry-mounted crane has the following characteristics that: the foldable hoisting arm structure is convenient to transport, and the multi-field application of the lorry-mounted crane is facilitated; and the problem of short-range hoisting operation of goods during hoisting is solved.
Description
Technical field
The utility model has related to a kind of lorry-mounted crane, relates in particular to a kind of folding crane arm structure of lorry-mounted crane.
Background technology
Lorry-mounted crane is meant and is installed on the car chassis, within the specific limits many actions elevator machinery of vertical-lift and horizontal carrying heavy goods.According to lever principle, under the certain situation of pressure, fulcrum is far away more, and needed power is just more little.In the lorry-mounted crane transportation, can't fold owing to flexibly connect still between each arm of crane arm, its length and volume cause transportation extremely inconvenient, receive the environmental constraints factor more; And when lifting job closely, extremely inconvenient by the goods handling in the crane arm brachium scope, can't fold the completion lifting job.
The utility model content
The technical matters that the utility model will solve is in order to overcome technological deficiency recited above, a kind of folding crane arm structure of lorry-mounted crane to be provided.
In order to solve technical matters recited above, the utility model is taked following technical scheme:
The utility model provides a kind of folding crane arm structure of lorry-mounted crane; Include column, basic arm and principal arm; Basic arm is connected with column; Be provided with transition arm between basic arm and the principal arm, be provided with back folding connecting rod mechanism and the back amplitude oil cylinder that acts on back folding connecting rod mechanism between said column and the basic arm.
One end of described back amplitude oil cylinder is arranged in the column.
Folding connecting rod mechanism and the preceding amplitude oil cylinder that acts on preceding folding connecting rod mechanism before being provided with between described basic arm and the transition arm.
An end of amplitude oil cylinder is arranged in the basic arm before described.
The utility model makes up through setting up the folding connecting rod structure between column, basic arm and the principal arm of crane arm; And basic arm and column inside respectively assemble amplitude oil cylinder control before folding connecting rod structure and back folding connecting rod mechanism; In handling or in transportation, need fold when handling hoisting crane, the folding yardstick of controlling forward and backward folding connecting rod structure through forward and backward amplitude oil cylinder is accomplished the folding process of crane arm.
The utlity model has following characteristics:
1) the multi-field application of truck-mounted crane machine is convenient in convenient transportation.
2) solve in the handling process the closely lifting job of goods.
Description of drawings
Fig. 1 is the structural representation after the crane arm of the utility model launches.
Fig. 2 is the structural representation after the crane arm of the utility model folds.
Among the figure, 1. base, 2. column, 3. basic arm, 4. principal arm, 5. transition arm, 6. before folding connecting rod mechanism, 7. before amplitude oil cylinder, 8. back folding connecting rod mechanism, 9. back amplitude oil cylinder, 10. supporting leg.
The specific embodiment
Please consult Fig. 1 in the lump.As shown in the figure; Lorry-mounted crane includes base 1 with supporting leg 10, is installed in the folding crane arm structure on the base 1; Wherein folding crane arm structure includes column 2, basic arm 3 and principal arm 4; Basic arm 3 is connected with column 2, is provided with transition arm 5 between basic arm 3 and the principal arm 4, is provided with back folding connecting rod mechanism 8 and the back amplitude oil cylinder 9 that acts on back folding connecting rod mechanism 8 between said column 2 and the basic arm 3.One end of described back amplitude oil cylinder 9 is arranged in the column 2.Folding connecting rod mechanism 6 and the preceding amplitude oil cylinder 7 that acts on preceding folding connecting rod mechanism 6 before being provided with between described basic arm 3 and the transition arm 5.An end of amplitude oil cylinder 7 is arranged in the basic arm 3 before described.
The utility model is set up the folding connecting rod structure on crane arm, and before controlling through amplitude oil cylinder folding connecting rod structure and back folding connecting rod mechanism to reach the effect of folding crane arm.
Claims (4)
1. the folding crane arm structure of a lorry-mounted crane; Include column, basic arm and principal arm; Basic arm is connected with column; Be provided with transition arm between basic arm and the principal arm, it is characterized in that: be provided with back folding connecting rod mechanism and the back amplitude oil cylinder that acts on back folding connecting rod mechanism between said column and the basic arm.
