In addition, during high-altitude work, the higher work site can lead to overhauing the focus of dolly too high, easily takes place to empty in the use, through add the supporting leg in bottom plate department, reduces the focus of overhauing the dolly to the use that makes the maintenance dolly is more firm.
Description
Technical Field
The invention relates to an overhauling device, in particular to a novel multipurpose overhauling trolley.
Background
The maintenance process of the equipment in the steel industry is complex, and the equipment is taken off and landed, operated at high altitude, lifted by weight, transferred and operated. The traditional maintenance tool is single in function, large in size and not suitable for operation in narrow space. When large-tonnage equipment is lifted, a travelling crane or a tire crane and the like are usually selected, but the travelling crane and the tire crane cannot be used due to the influence of space, and at the moment, a chain block is needed. However, a proper and reliable hoisting point is not available on the site, a tripod is required to be used as an auxiliary hoisting point, the disassembly and the assembly are time-consuming and labor-consuming, the movement is inconvenient, and the overhauling efficiency is low.
In addition, when a high-altitude lifting operation is performed, a steel pipe or a column with a sufficient length is required to be erected on the ground or a platform by manual assistance, and then a mechanical or hydraulic jack is used for the lifting operation. In the operation process, cross operation exists, the hydraulic jack supports and the herringbone ladder or the hand foot frame interfere with each other, and the support column cannot be adjusted in height, so that the high-altitude weight lifting operation greatly limits the overhaul efficiency. Simultaneously, this kind of maintenance operation mode has this very big potential safety hazard, in case support unevenness to cause empting, empting of stand and hydraulic ram instrument can cause the injury to the workman.
Disclosure of Invention
The invention provides an online segmentation cutting device for heat-treated steel plates, which solves the technical problems that the traditional maintenance trolley cannot carry out high-altitude weight lifting operation, wheels at the bottom of the movable trolley have weak bearing capacity and unstable gravity center in the weight lifting process, realizes high-altitude supporting operation of the movable maintenance trolley, and ensures the stability and safety of the trolley in the using process.
The invention provides a maintenance trolley which comprises a trolley body,
comprises a mobile platform, a ladder stand and a supporting mechanism;
the crawling ladder comprises a fixed crawling ladder and a rotary crawling ladder;
a hollow fixed supporting column is arranged at the joint of the top ends of the fixed crawling ladder and the rotary crawling ladder;
the supporting mechanism comprises a movable supporting rod, and the movable supporting rod is arranged in the fixed supporting column; the top of the movable support rod is provided with a hydraulic jack, and the bottom of the movable support rod is provided with an automatic foot-retracting device;
the automatic foot-retracting device comprises a pressing plate and a spring arranged above the pressing plate, the spring is stressed and compressed, the movable supporting rod extends out of the fixed supporting column and is supported on the ground, the spring loses force and recovers, and the movable supporting rod retracts into the supporting column.
In detail, in order to realize overhauing the eminence equipment, it is rotatory cat ladder to required height, at steel equipment maintenance in-process, often need to prop large-tonnage equipment and lift, will movable support rod follows extract out in the fixed stay post, adjust to suitable height, the jack atress, automatic receipts foot device atress simultaneously, the spring is in compress under the effect of holding-down plate and pressure, movable support rod downstream is to falling to the ground. At this moment, carrying out the weight lifting operation in-process, the activity bracing piece bears the decurrent pressure of jack, and the moving platform who is used for moving the maintenance dolly does not bear the gravity of the equipment of lifting, has avoided in the maintenance process, and large-tonnage equipment is too big to the pressure of overhauing the dolly, and leads to the injury to overhauing the dolly. After the operation of propping up is ended, the jack loses power, the spring resumes to natural state, and the activity bracing piece receives automatic the retrieving to the fixed stay post after the elasticity of spring in, avoids causing the influence to the removal of overhauing the dolly. Through will propping and lift the mechanism and the maintenance dolly that is commonly used and combine, not only realized the eminence and propped the maintenance operation, avoided moreover because the large-tonnage equipment pressure too big potential safety hazard that exists to moving platform pressure, accomplish the maintenance of equipment more fast, conveniently, accurately.
Furthermore, the pressing plate comprises a first pressing plate arranged on the upper surface of the moving platform and a second pressing plate welded on the movable supporting rod, and the spring is arranged above the first pressing plate;
the automatic foot-retracting device further comprises a stud, and the first pressing plate and the second pressing plate are fixed through the stud.
Further, the movable supporting rod penetrates through the moving platform to be in contact with the ground.
In detail, the first pressing plate is arranged on the surface of the moving platform, and when the jack is stressed and the movable supporting rod moves downwards, the spring can be limited between the first pressing plate and the upper nut, so that the spring is compressed to generate elastic force. The second pressing plate is welded with the movable supporting rod and is used for being connected with the spring and the first pressing plate, so that the movable connecting rod and the automatic foot retracting device are fastened into a whole, the movable supporting rod stretches out to be held with the ground when the automatic foot retracting device is used, and the automatic foot retracting device retracts into the fixed supporting rod after the use is finished, and the movement of the maintenance trolley is not influenced.
Furthermore, a worm and gear speed reducer, a chain wheel and a chain wheel base are arranged on the side face of the fixed support column, the chain wheel base is fixedly connected with the rotary crawling ladder, and the worm and gear speed reducer and the chain wheel drive the rotary crawling ladder to rotate.
