Abstract
The utility model relates to a folding conveying ladder which is composed of a chassis of a truck crane, a hydraulic system, a plurality of conveying frames and a tension device. The utility model is characterized in that the conveying frames which are connected by pin shafts can be raised, lowered and folded by the hydraulic system. Chains and conveying belts, which can be moved in the conveying frames, are arranged in the conveying frames. The utility model has the advantages of stable rise and fall, multiple functions, simple structure, convenient maintenance, wide range of application, etc.
Description
The utility model belongs to mechanical field, relates to a kind of improvement of conveying machinery.
The single conveyer that is used for convey materials is arranged in conveying machinery at present, the conveyer that the special material of special conveying is also arranged, and fire-fighting and skyscraper is speedily carried out rescue work and the fire-fighting process in be used for carrying distress personnel and material and fire-fighting process, also be not used in now the load transfer device of skyscraper.
The purpose of this utility model provide a kind of fire-fighting, conveying, maintenance and various industry that can be used in skyscraper and aloft work used and have motor-driven strong, a multi-functional collapsible transporting ladder.
The technical solution of the utility model is that terraced mounting is fixed on the cylindrical wheel by bearing pin, link to each other and to fold by bearing pin between the more piece transportation frame, in every joint transportation frame guardrail is installed, the lifting of each transportation frame is finished by the hydraulic support that is installed in the framework both sides, chain, chain slideway and load-transfer device are housed in transportation frame, the rescue pocket is housed on load-transfer device, rescues pocket and can adorn people or article; Chain is finished cooperating of chain and transportation frame with the lifting of transportation frame by tightening device, to keep the working stability of chain.
Feature of the present utility model is that collapsible transporting ladder is by hydraulic efficiency pressure system, the more piece transportation frame, feedway and tightening device constitute, link to each other by bearing pin between the more piece transportation frame, guardrail is housed on transportation frame, the transportation frame front end is equipped with bench board at the top, hydraulic lifting cylinder is equipped with in each transportation frame both sides, chain is housed in transportation frame, chain slideway and load-transfer device, load-transfer device links to each other with chain, and the rescue pocket is housed on load-transfer device, the ladder mounting links to each other with cylindrical wheel by bearing pin, in terraced mounting the place ahead chain stretching device is housed, tightening device is to be linked to each other with chain by tensioning shaft, tensioning shaft is by the hydraulic actuating cylinder control that is contained on the terraced mounting, and HM Hydraulic Motor is housed on terraced mounting is meshed with chain.
Principle of work of the present utility model is that a whole set of folding transporting ladder is installed on the chassis of cranemobile, the wheel word of transporting ladder adopts the wheel word of existing wheel crane, all liftings drive hydraulic ram by HM Hydraulic Motor and finish, when needs are articles conveyed, start and be contained in the HM Hydraulic Motor that terraced mounting links to each other with chain and make chain movement drive the load-transfer device motion, the lifting of every joint transportation frame is finished by the oil cylinder that is contained in its both sides, and is collapsible between the transportation frame.
Good effect of the present utility model is to adopt transportation frame collapsible and by fluid control, area occupied is little, load-transfer device is housed in transportation frame can in the aloft work process, carries out the conveying of material, can be applicable to maintenance, the decoration of fire-fighting, skyscraper, the needs of the operations such as industry, petrochemical complex of also can powering; The utlity model has advantages such as lifting is steadily reliable, function is many, simple in structure, easy to maintenance.
Accompanying drawing is a concrete structure of the present utility model:
Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is the transportation frame raising structure figure in the utility model.
In Fig. 1, be connected with terraced mounting 2 by bearing pin on the large cylindrical gear 1 of expression wheel crane main frame, more piece transportation frame 4 links to each other by bearing pin, hydraulic lifting cylinder 3 all is equipped with in both sides in terraced mounting 2 and transportation frame 4, and guardrail 5 is housed on transportation frame 4, the transportation frame front end is equipped with bench board 6 at the top, on terraced mounting 2, HM Hydraulic Motor 7 is housed, HM Hydraulic Motor 7 is meshed by sprocket wheel and chain 8, chain 8 links to each other with the sprocket wheel of tensioning shaft 9, and tensioning shaft 9 links to each other with terraced mounting 2 by hydraulic actuating cylinder 10.
Be illustrated in Fig. 2 slideway 11 is housed in the transportation frame 4, chain 8 links to each other with load-transfer device 13, and rescue pocket 14 is housed on load-transfer device 13.
