Abstract
The utility model discloses a lorry-mounted crane with link mechanisms, which comprises a base, a vertical column, a basic jib, a main jib and a transition jib, wherein the basic jib is connected with the vertical column mounted on the base, and the transition jib is arranged between the basic jib and the main jib. A rear link mechanism and a rear variable-amplitude oil cylinder acting on the rear link mechanism are arranged between the vertical column and the basic jib, and a front link mechanism and a front variable-amplitude oil cylinder acting on the front link mechanism are arranged between the basic jib and the transition jib. When oil is supplied to the variable-amplitude oil cylinders, piston rods are pushed out by huge pressure to drive the link mechanisms to realize reciprocating variable-amplitude movement. The link mechanisms enable fulcrums to be distant to function in boosting, and can be used for transferring high power, so that the lifting capacity of the crane is larger under the same pressure. Besides, a crane boom is guaranteed to have constant lifting capacity at any positions, and the service life of the crane boom is effectively guaranteed.
Description
Technical field
The utility model has related to a kind 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.And traditional lorry-mounted crane does not have between column and basic arm and at basic arm and transition arm connecting rod mechanism is set, and the bigger pressure of the same weight needs of handling makes oil consumption bigger, the wasting of resources, and be unfavorable for energy-conserving and environment-protective.When lifting by crane heavier article, make that binding site place load between any two is bigger simultaneously, the member at this position damages easily, has a strong impact on its service life.
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 lorry-mounted crane with connecting rod mechanism 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 lorry-mounted crane with connecting rod mechanism; Include base, column, basic arm, principal arm and transition arm; Described column is installed on the base; Basic arm is connected with column, is provided with transition arm between basic arm and the principal arm, is provided with rear linking rod mechanism and the back amplitude oil cylinder that acts on rear linking rod mechanism between said column and the basic arm.
Be provided with front rod mechanism and the preceding amplitude oil cylinder that acts on front rod mechanism between described basic arm and the transition arm.
The utility model is through in installing connecting rods mechanism between the column and basic arm of lorry-mounted crane, between basic arm and the transition arm; Amplitude oil cylinder is under the situation of fuel feeding, and piston rod is released by huge pressure, is being with connecting rod mechanism; Realize reciprocal luffing motion; Because connecting rod mechanism has boosting function, under equal pressure, the load-carrying ability of loop wheel machine is just bigger.Link to each other with lower pair between member in the connecting rod mechanism, lower pair two elements are the face contact, and pressure is lower bearing under the condition of same load; Thereby can be used for transmitting bigger power, and use connecting rod mechanism here, not only make fulcrum become far away; And play the effect of reinforcement; Improve load-carrying ability, and guarantee under any position of crane arm constant hoisting capacity is arranged, guarantee its service life effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1. base, 2. column, 3. basic arm, 4. principal arm, 5. transition arm, 6. front rod mechanism, 7. before amplitude oil cylinder, 8. rear linking rod mechanism, 9. the back amplitude oil cylinder.
The specific embodiment
See also Fig. 1.As shown in the figure; A kind of lorry-mounted crane with connecting rod mechanism includes base 1, column 2, basic arm 3, principal arm 4 and transition arm 5; Described column 2 is installed on the base 1; 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 rear linking rod mechanism 8 and the back amplitude oil cylinder 9 that acts on rear linking rod mechanism 8 between said column 2 and the basic arm 3.Be provided with front rod mechanism 6 and the preceding amplitude oil cylinder 7 that acts on front rod mechanism 6 between described basic arm 3 and the transition arm 5.
The utility model is installing connecting rods mechanism between the column of lorry-mounted crane and basic arm and between basic arm and transition arm, and the connecting rod mechanism between column and the basic arm is referred to as rear linking rod mechanism; Connecting rod mechanism between basic arm and the transition arm is referred to as front rod mechanism.The working process of connecting rod mechanism is following: amplitude oil cylinder is under the situation of fuel feeding, and piston rod is released by huge pressure, is being with connecting rod; Realize reciprocal luffing motion; Because connecting rod mechanism all has boosting function, under equal pressure, the load-carrying ability of loop wheel machine is just bigger.Connecting rod mechanism is an example later on, and amplitude oil cylinder is being with rear linking rod mechanism under huge oil pressure promotes, and promotes basic arm and does the luffing motion; When oil cylinder is full reduced, the lowest part when basic arm is in the loop wheel machine lifting; When oil cylinder is stretched entirely, the highest point when basic arm is in the loop wheel machine lifting.In like manner, the front rod mechanism action also is like this.When forward and backward amplitude oil cylinder is in when full reduced simultaneously, lorry-mounted crane is in folded state: when forward and backward amplitude oil cylinder is in when stretching entirely simultaneously, lorry-mounted crane is in the highest thing state that hangs.
Claims (2)
1. lorry-mounted crane with connecting rod mechanism; Include base, column, basic arm, principal arm and transition arm; Described column is installed on the base; Basic arm is connected with column, is provided with transition arm between basic arm and the principal arm, it is characterized in that: be provided with rear linking rod mechanism and the back amplitude oil cylinder that acts on rear linking rod mechanism between said column and the basic arm.
2. lorry-mounted crane as claimed in claim 1 is characterized in that: be provided with front rod mechanism and the preceding amplitude oil cylinder that acts on front rod mechanism between described basic arm and the transition arm.
