Description
Technical Field
The utility model relates to a jack-up transportation equipment, concretely relates to luffing cylinder locates lorry-mounted jack-up transport vechicle of jib loading boom top.
Background
The truck with crane is a special vehicle with transportation function and lifting function, and is very convenient to use. The crane assembly is additionally arranged on the chassis of the vehicle, so that the height and the weight of the vehicle body are increased, the height and the weight of the crane arm and the amplitude-variable oil cylinder are required to be reduced in order to prevent the vehicle from being ultrahigh and overweight, and the lifting capacity of the crane assembly is reduced due to the fact that the amplitude-variable oil cylinder is arranged below the crane arm. How to ensure the lifting capacity without causing the vehicle to be ultrahigh is a problem to be solved by the vehicle.
Disclosure of Invention
The utility model aims at providing a neither reduce hoisting capacity, the crane jib loading boom top's lorry is located to the not super high amplitude oil cylinder of vehicle height again.
The technical solution of the utility model is that: the crane comprises a chassis, and a cab, a crane assembly and a carriage which are sequentially arranged on the chassis from front to back, wherein the crane assembly comprises a base, a hydraulic support leg, a rotary disc, a rotary upright post, a crane boom and a luffing cylinder, the tail end of the crane boom is hinged with the middle part of the rotary upright post, the tail end of a luffing cylinder body is hinged with the upper end part of the rotary upright post, and the end part of a cylinder rod is hinged with the crane boom towards the direction of a crane head of the crane boom.
The technical effects of the utility model are that: the lifting and transporting capacity of the crane is ensured, the lifting capacity is not reduced, the vehicle height is not ultrahigh, and the crane can meet the requirements of traffic departments. The variable-amplitude oil cylinder is arranged above the lifting arm, so that the length of the oil cylinder is not limited by the length and the space, the length of the oil cylinder can be designed to be longer as much as possible under the condition of not influencing the lifting elevation angle, the lifting moment can be increased, the diameter of the oil cylinder can be reduced, the production cost can be reduced, and the weight of a crane assembly can be reduced. The lifting device has the advantages of simple structure, low manufacturing cost, light weight and high lifting capacity, and is suitable for lifting operation under various conditions.

Detailed Description
As shown in figure 1, the hydraulic lifting device comprises a chassis 1, and a cab 2, a crane assembly 3 and a carriage 4 which are sequentially arranged on the chassis 1 from front to back, wherein the crane assembly 3 comprises a base 31, a hydraulic support leg 32, a rotary disc 33, a rotary upright post 34, a crane boom 35 and a luffing cylinder 36, the tail end of the crane boom 35 is hinged with the middle part of the rotary upright post 34, the tail end of a cylinder body of the luffing cylinder 36 is hinged with the upper end part of the rotary upright post 34, and the end part of the cylinder rod is hinged with the crane boom 35 towards the direction of a lifting head of the crane boom 35.
The base 31 is installed on the chassis 1, the rotary disk 33 is positioned above the base 31 and horizontally and rotatably installed on the base 31, and the lower part of the rotary upright column 34 is fixedly installed on the rotary disk 33.
The rotary column 34 is attached to the rotary plate 33 with its upper end inclined in the direction opposite to the boom 35.
The cargo boom 35 comprises an outer sleeve 37, a plurality of sections of telescopic sleeves sleeved in the outer sleeve 37 and a lifting head 38, wherein the lifting head 38 comprises a fixed pulley block 39 and a lifting hook 40, the fixed pulley block 39 is arranged at the front end of the innermost telescopic sleeve, a movable pulley block 41 matched with the fixed pulley block 39 is arranged on the lifting hook 40, and the fixed pulley block 39 and the movable pulley block 41 are connected through a lifting steel wire rope 42 matched with each other.
The rear end part of the outer sleeve 37 of the cargo boom 35 is hinged with the rotary upright post 34, and a luffing cylinder rod hinge seat 43 is arranged at the middle front part of the upper side of the outer sleeve 37 of the cargo boom 35.
The hydraulic support leg 32 is composed of a left horizontal support leg, a right horizontal support leg, a left vertical support leg and a right vertical support leg, the left horizontal support leg and the right horizontal support leg are horizontally arranged on the base 31, and the left vertical support leg and the right vertical support leg are respectively arranged at the end parts of the left horizontal support leg and the right horizontal support leg, which are extended outwards.
The design characteristics are as follows: when the lifting arm 35 is horizontally placed, the rod of the luffing oil cylinder 36 is in the longest extending state, and the lifting arm 35 is parallel to the ground. When the amplitude-variable oil cylinder 36 is contracted, the front end of the cargo boom 35 is lifted up to form a certain angle with the ground, and the maximum angle can reach 76 degrees, at the moment, the cargo boom 35 has the maximum lifting capacity, and the cargo can be lifted up or down through the lifting head 38. The lifting arm 35 is arranged below the amplitude cylinder 36, the distance between the two is determined according to requirements, the tail end of the cylinder body of the amplitude cylinder 36 is hinged with the uppermost end of the rotary upright post 34, the rod of the amplitude cylinder 36 is hinged with the middle front part of the outer sleeve 37 of the lifting arm 35, and the hinged point is determined by the bearing capacity of the lifting arm 35. The lifting force is required to be large and the lifting force is close to the direction of the lifting head 38, because the hinged point of the cylinder rod of the luffing cylinder 36 moves forwards in the direction of the lifting head 38, the lifting moment can be increased, the bearing capacity of the lifting arm 35 can be reduced, meanwhile, the cross section area of the lifting arm 35 can be reduced, the weight of the lifting arm 35 can be reduced, the material is saved, and the cost is reduced.
