The crane has the technical effect brought by the crane control chamber lifting device.
Description
Technical Field
The utility model relates to a hoist control room elevating gear.
The utility model discloses still relate to a hoist.
Background
The existing automobile crane control room is fixedly arranged on a crane rotary table, a driver controls the hoisting operation of the crane in the control room, and the position of the control room is relatively fixed. But the prior art has the following disadvantages: 1. during hoisting operation, a driver sitting in the control cabin often can be shielded from sight by peripheral objects, so that potential safety hazards exist; 2. the control room is fixedly arranged on the rotary table of the crane and is close to devices with high noise and high temperature, such as an engine, a hydraulic system, a transmission mechanism and the like, so that the operation environment is severe; 3. the control cabin is arranged in the front lower part of the winding device, a driver cannot observe the working condition of the winding steel wire rope, and the driver cannot find the abnormal conditions such as rope disorder, twisting and the like of the steel wire rope in time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a hoist control room elevating gear that rational in infrastructure, can adjust control room and revolving stage distance in a flexible way is provided.
The utility model aims to solve the technical problem that still provide a hoist.
In order to solve the technical problem, the utility model provides a lifting device of a crane control room;
comprises a plurality of lifting trusses and at least one group of lifting components;
the lifting trusses are sequentially and vertically arranged in parallel, the lifting truss on one side edge in the arrangement direction of the lifting trusses is vertically and fixedly connected to a rotary table of the crane, and the lifting truss on the other side edge in the arrangement direction of the lifting trusses is fixedly connected with the side wall of a control cabin of the crane;
the lifting assembly is arranged between any two adjacent lifting trusses and comprises a lifting oil cylinder, a cylinder barrel and a piston rod of the lifting oil cylinder are fixedly connected with the two corresponding adjacent lifting trusses respectively, and the trend of the lifting oil cylinder is in the vertical direction.
After adopting such structure, the control cabin of hoist is driven to move steadily at the effect of lifting unit to the lift truss.
This hoist control room elevating gear has following advantage: 1. the control cabin can freely control the lifting height according to the requirement, and provides the best sight for operation; 2. the device is far away from a noise source and a high-temperature source, so that the operation comfort is improved; 3. the abnormal working conditions of equipment such as winches can be found in time, and the operation safety is improved.
A slide rail is arranged between any two adjacent lifting trusses of the crane control chamber lifting device, the trend of the slide rail is in the up-down direction, and the two adjacent lifting trusses can relatively move along the slide rail; after the structure is adopted, the sliding rail can restrain the lifting movement track of the lifting truss and plays a role in assisting in supporting the whole device and the control room.
In order to solve the technical problem, the utility model provides a crane, which is provided with the crane control room lifting device; after adopting such structure, this hoist has the technical effect that hoist control room elevating gear brought.
Drawings
FIG. 1 is a diagram showing a state of use of an embodiment of the elevator apparatus for a cage of a crane.
Fig. 2 is a right side view of fig. 1.
Detailed Description
As shown in fig. 1 to 2
The crane cage 51 lifting device comprises four lifting trusses 1 and three groups of lifting assemblies.
Four lifting trusses 1 are vertically arranged, four lifting trusses 1 are parallel in sequence from left to right, the lifting truss 1 at the leftmost side and the right side wall of a control chamber 51 of a crane are fixed through bolts, the lifting truss 1 at the rightmost side is directly fixed with a rotary table 52 of the crane through a plurality of supports, a sliding rail 2 is arranged between any two adjacent lifting trusses 1, the trend of the sliding rail 2 is in the up-down direction, and the two adjacent lifting trusses 1 can move relative to each other along the sliding rail 2.
Every group lifting unit sets up between arbitrary two adjacent lifting trusses 1, every group lifting unit includes lift cylinder 3, lift cylinder 3's cylinder passes through the bolt fastening on two adjacent lifting trusses 1 on right side in 1, lift cylinder 3's piston rod tip passes through the bolt fastening on two adjacent lifting trusses 1 in left lifting trusses 1, all lift cylinders 3 connect in parallel through hydraulic line, all lift cylinders 3 atress simultaneously, reduce hydraulic system pressure, and guarantee every lifting truss 1 synchronous motion.
The hydraulic oil source of the lifting oil cylinder 3 can be taken from the existing hydraulic system of the crane, the action of the telescopic oil cylinder is controlled by the electromagnetic directional valve to realize the lifting and stopping of the control room 51, and a balance valve 4 can be arranged on each lifting oil cylinder 3 to prevent dangerous accidents such as too fast descending of the control room 51, accidental pressure loss of the hydraulic system and the like.
A drag chain belt (not shown) is provided between the cage 51 and the crane control system, and the drag chain belt is used for placing flexible moving parts such as hydraulic hoses and cables to prevent the flexible moving parts from being damaged when the cage 51 is lifted.
The crane control room is arranged on the crane, so that the crane has the technical effect brought by the crane control room lifting device;
when the lifting truss device is used, the four lifting trusses 1 realize relative parallel movement under the action of the lifting oil cylinders 3 and the sliding rails 2.
The above description is only one embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and improvements can be made without departing from the principle of the present invention, and these should also be considered as belonging to the protection scope of the present invention.
