Description
Technical Field
The invention relates to an electric inspection well cover unsealing forklift.
Background
Along with the rapid development of regional economy, the urban scale serving as a development sign of the regional economy is gradually enlarged, the requirement of modern urban functions on power supply is continuously improved, the traditional overhead transmission line needs to directly occupy a small amount of land except for a tower, the overhead transmission line does not directly occupy the land, and the land utilization can be influenced due to the occupation of the overhead transmission line on the space above the land.
With the increase of tall buildings in cities, a plurality of obstacles are brought to the crossing of the traditional overhead transmission line, and in rapidly expanding urban areas, attention should be paid to the coordination of the arrangement of line corridors and the development of cities so as not to be quickly trapped in the heavy enclosure of urban buildings. For overhead transmission lines that have been sunk into urban areas, it is desirable to incorporate a retrofit into a green belt or underground cable line.
With the increase of underground cable lines, the number of cable trenches and electric inspection wells is increasing continuously, electric workers need to open covers on the cable trenches or the electric inspection wells to operate when cables are maintained, maintained and assisted by the electric workers in daily life, the electric workers often cannot spread the cables due to site limitation, the covers on the cable trenches or the electric inspection wells are opened or covered, the electric workers still need heavy and dangerous labor, the operation efficiency is very low, particularly in summer, the electric workers often sweat down the back, the electric workers are shouldered by their wet bodies, lifted by the wet bodies and easily slip, equipment is damaged, and the electric workers can hurt themselves and companions.
Therefore, the problem is solved by the targeted development, and the personal safety and the good property of the power workers are ensured.
Disclosure of Invention
Aiming at the problems, the invention provides the electric inspection well cover unsealing forklift which is light in self weight and very flexible, and can easily open or cover a cable trench cover or an electric inspection well cover through manual or electric lifting, so that the labor intensity and the working efficiency of electric workers are synchronously improved, and the safety is greatly improved.
The invention is realized by the following steps: the electric inspection well cover unsealing forklift is characterized in that: jacks of the positioning columns are distributed on the cross arm, and lifting type trolley assemblies are arranged at two ends of the cross arm;
the support of the lifting trolley assembly is provided with a lifting device and an operating rod connector; the operating rod is arranged in the operating rod connector and is connected with the transmission device in the lifting device; the movable wheels are arranged at the longitudinal end and the transverse end under the support to form a universal trolley with the movable wheels at the front end, the rear end, the left end and the right end under the support, and the universal trolley can turn, turn around or move straightly under the action of the control lever.
The lifting device comprises a hydraulic jack and an electric lifting device.
The moving wheels comprise directional wheels and universal wheels.
The invention has the following functions:
1. the electric power car has light dead weight, and the control lever is provided with handles, so that 2 electric power workers can easily lift the electric power car from the electric power special car by respectively holding the handles at two ends; on the contrary, the electric power special vehicle can be easily lifted to the electric power special vehicle after being used.
2. The forklift is very flexible to operate, 2 electric workers respectively hold handles at two ends to push and pull, and the forklift can be driven to move in a straight way, a transverse way and an inclined way or can be driven to rotate in a single direction and a double direction, can operate in a limited space, and has very strong penetrating and spanning capabilities.
3. The operation of the inspection well is very light, 2 electric workers respectively hold handles at two ends to swing up and down, and a cross arm supported by a hydraulic jack type lifting device can easily lift a cable trench cover or an electric inspection well cover and then move away; or the cross arm supported by the electric lifting device directly lifts the cable trench cover or the electric inspection well cover and then moves away; otherwise, the cable trench cover or the electric inspection well cover can be put down and removed after being moved to the right position.
4. The jack of reference column is being distributed on the cross arm of this forklift, and the reference column can be inserted in required jack, and the lifting rope inlays and just can prevent shifting during the operation of unsealing of cable trench cover or electric power inspection shaft lid in the reference column.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic perspective view of the electric inspection well cover unsealing forklift.
Fig. 2 is a partially enlarged schematic view of the electric inspection well cover unsealing forklift.
In the figure: 1. the lifting device comprises a cross arm, 2 jacks, 3 lifting devices, 4 lifting trolley assemblies, 5 operating rods, 6 return springs, 7 operating rod connectors, 8 moving wheels and 9 supports.
Detailed Description
As shown in the figure, jacks 2 of the positioning columns are distributed on the cross arm 1, and lifting type trolley assemblies 4 are arranged at two ends of the cross arm 1.
In the lifting trolley assembly 4, the support 9 is provided with the lifting device 3 and the operating lever connector 7, and the lifting device 3 comprises a hydraulic jack and an electric lifting device; the operating rod 5 is arranged in an operating rod connector 7, and the operating rod 5 is connected with a transmission device in the lifting device 3; moving wheels 8 are arranged at the longitudinal end and the transverse end below the support 9, and the moving wheels 8 comprise directional wheels and universal wheels; the universal trolley is supported by moving wheels 8 at the front, the rear, the left end and the right end below a support 9, and can turn, turn around or move straightly under the action of the control lever 5.
During operation, the forklift moves the cable trench cover or the electric inspection well cover, the positioning column is inserted into a required insertion hole, the lifting rope is embedded in the positioning column, two ends of the lifting rope hook lifting rings of the cable trench cover or the electric inspection well cover, 2 electric workers respectively hold handles at two ends to swing up and down, a cross arm supported by the hydraulic jack type lifting device can easily lift the cable trench cover or the electric inspection well cover, or the cross arm supported by the electric lifting device directly lifts the cable trench cover or the electric inspection well cover and then moves away; otherwise, the cable trench cover or the electric inspection well cover can be put down and removed after being moved to the right position.
