Abstract
A slipping overhead trolley comprises a trolley which is a frame construction, wherein a slip beam is provided on the bottom of the trolley, an orbit is provided on the top of the trolley, a ground orbit is engaged with the slip beam which is on the bottom of the trolley, and a traction device which is a hydraulic cylinder or a cable hoist is connected with the trolley. The slipping overhead trolley of the utility model has the advantages of simple structure, big bearing capability and repeatable utilization, thereby totally meeting the requirement that a high furnace is transported to the high furnace foundation after a short duration complete repair and furnace preassembling.
Description
Technical field
The utility model relates to transportation device, and erecting equipment is moved in the short range that particularly is used for iron and steel metallurgy enterprise blast furnace overhaul and construction, other industry main equipment.
Background technology
Large blast furnace is installed the basis generally has drop more than 5 meters with ground, adopt the pre-assembling of short-term overhauling technology body of heater generally to carry out, will be installed to the drop problem that will solve on the blast furnace foundation more than 5 meters after the pre-assembling of body of heater like this on the ground that has with a certain distance from blast furnace foundation.Tradition blast furnace overhaul and newly-built owing to adopt the online lifting of fritter furnace shell does not have the drop problem.Small furnace is because blast furnace foundation is lower, and it is low weight to assemble body of heater weight in advance, and this problem solves simpler.External large blast furnace short-term overhaul, construction solve the pre-assembling of body of heater and the drop problem is installed has several method, 1) set up and the level assembly platform of blast furnace foundation at the blast furnace periphery, a section body of heater is assembled on this platform in advance greatly.The method is at the aloft work poor stability, and big section body of heater heavily has about 1000 tons, and scaoffold sets up the cost height.2) body of heater utilizes special suspender that body of heater is winched on the specific combination carrier after assemble in advance on ground, purpose made leveling framework is installed on the combined traffic car, sliding rail is arranged on the framework, framework and combined vehicle height and blast furnace foundation height are basic identical, transport trolley is transported to blast furnace foundation with body of heater and is connected with the basic sliding rail of going up, and blast furnace is passed to the position, base center by sliding rail.The method requires that the specific combination carrier is arranged, vehicle-mounted overhead leveling chassis complex structure, and cost is also very high.
The mobile transportation of prior art chassis divides two big classes: the one, and the mobile of chassis is the rolling wheel, do not need track, places the delivery article on the car, the article of delivery are parallel motion on chassis not; Another kind is that wheel is arranged at the chassis bottom, and wheel moves in orbit, and the article of delivery do not have parallel motion on the chassis that moves height yet.Chinese patent CN88221338.5 disclosed " the light-duty chassis of multipurpose track " for example, its structural feature is that car load has adopted structure easy to assemble, four wheels are connected in respectively on two blocks by four minor axises, two blocks are connected together by connecting rod, girder is placed in the groove of two blocks, be provided with disk spring therebetween, can effectively reduce the car load center of gravity, and can carry balance adjustment.In addition, between the contact surface of girder and bearing plate, be provided with one deck polytetrafluoroethylene slide block, the needs when turning to satisfy.This car can be used for rail transport, can do the traveling gear of lifting appliance again, is applicable to the transportation of beam-shaped member and sets up.Prior art is confined to deliver article can carry out the level transportation on a horizontal surface.
Summary of the invention
The purpose of this utility model provides a kind of sliding type overhead crane, to solve pre-assembling in last furnace shell ground and the drop problem of installing to blast furnace foundation.
For achieving the above object, the technical solution of the utility model, sliding type overhead crane, it comprises, the chassis body, it is a framed structure, its bottom is provided with the slippage beam; The top is equipped with track; Ground rail cooperates with chassis body bottom slippage beam; Push unit is connected with the chassis body.
Further, described push unit is hydraulic actuating cylinder or winch.
The utility model chassis itself is a steel structure frame, and the bottom is provided with the slippage beam, can on ground rail, slippage advance, rather than wheel rolling; Track is arranged at the overhead crane top, and carriage on the track and article are the longer distance of parallel motion in orbit, and docks with the track implementation on taking charge of a plane, and article just can be transferred on other basis with certain altitude apace.This overhead crane also is furnished with relevant propelling unit and engine installation simultaneously.
The beneficial effects of the utility model
Sliding type overhead crane of the present utility model, simple in structure, carrying is big, reusable, can satisfy the requirement that is transported to blast furnace foundation after the pre-assembling of blast furnace short-term overhaul body of heater fully.
Description of drawings
Fig. 1 is the plan structure scheme drawing of the utility model one embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, sliding type overhead crane of the present utility model, it comprises, chassis body 1, it is a framed structure, its bottom is provided with four slippage beams 11; The top is equipped with track 12; Ground rail 2 cooperates with chassis body bottom slippage beam 11; Push unit 3 is connected with chassis body 1; This push unit 3 is hydraulic actuating cylinder or winch.
Blast furnace is after assembling on the carriage is finished, be pushed the transfer point center that moves to---a kind of special door type suspender that is used for lifting by crane large-scale body of heater specially, by the special hanger that is provided with on the transfer point carriage and body of heater thereof are risen to specified altitude, at this moment be installed in four (or two of overhead crane bottom one end, eight) hydraulic feed device is dragged in the transfer point carriage below with unloaded overhead crane, the transfer point hydraulic lifting apparatus is placed in carriage and body of heater thereof on the track on the overhead crane, after the center finished, four hydraulic feed devices that are installed in overhead crane bottom one end promote overhead cranes and dock to blast furnace foundation one side and with the basis beam that gets on the right track, carriage after butt joint is finished on the overhead crane is moved to the blast furnace foundation center by the body of heater that mounted hydraulic feed device promotes carriage and carrying, after carriage left overhead crane, overhead crane can continue to return the transportation that transfer point carries out other big section body of heater.
