Abstract
The utility model discloses a protective cover which comprises a cover body and bolts; and the protective cover is characterized in that the cover body is formed by two semicircular cover bodies; one end of each of the two cover bodies is cylindrical, and the other end of each of the two cover bodies is opened and conical; lugs which are bilaterally symmetrical are arranged at the joint of the two semicircular cover bodies; a bolt hole is formed in the center of each lug; and the two semicircular cover bodies are fixedly connected through the bolts. The device is arranged above an outlet flange of an oil line, which can change leakage direction of hydraulic oil, reduce the oil injection pressure, prevent the high-pressure oil from being transversely injected to personnel and equipment, and reduce occurrence of personnel safety and equipment accidents; and meanwhile, the device is convenient for maintenance management and disassembly and assembly, and can perform daily inspection on the flange and other parts conveniently.
Description
Technical field
The utility model relates to a kind of protective housing, is specifically related to a kind of hydraulic pressure flange-interface that prevents and sprays the safety enclosure of hurting sb.'s feelings.
Background technique
Because hydraulic equipment is widely used in modernized industrial and mineral enterprise, and hydraulic fluid pressure is higher (the employed hydraulic equipment pressure range of Taiyuan Iron and Steel Co. hot continuous rolling factory is 16MPa ~ 30 MPa) generally, the problem of thereupon bringing is exactly how to use safely and the lifting of maintenance technology, prevents the generation of all kinds of accidents.
The quantity of Taiyuan Iron and Steel Co. hot continuous rolling factory 1549 production line hydraulic cylinders has thousands of, and hydraulic pipe line always has been about 3 myriametres, carries out fairly large technical innovation in 2002, and valve platform and line arrangement are more concentrated.Hydraulic equipment has brought adverse effect to safety in production under situation easy to use.Because pressure is higher, when oil cylinder is carried out action, can produce huge vibration, interface to hydraulic pipe line and valve platform causes damage, cause accident generations such as leakage of oil injection easily, in case fluid is ejected into around operating personnel or the equipment, serious accident such as will cause great personal safety and catch fire is suffered heavy losses.F5 operation panel east side is provided with roll change hydrovalve platform under the Taiyuan Iron and Steel Co. hot continuous rolling factory finish rolling region operation platform, apart from operation panel nearer (2.5 meters), valve table oil way outlet flange oil pressure 16MPa, this position flange weld bond leakage of oil once took place at the beginning of 2011, fluid sprays to the just personnel of operation on operation panel, and is abnormally dangerous, simultaneously coloured silk drawn ground and pollute and damage, if fluid is directly injected on one's body the personnel, consequence is with hardly imaginable.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of safe, protective housing easily, avoids positions such as flange, interface high pressure oil transverse injection after the leakage of oils to take place and cause casualties accident or equipment accident.
The technical solution adopted in the utility model is: a kind of protective housing, comprise cover main body, bolt, it is characterized in that: described cover main body is made up of two semicircle cover bodies, one end of cover body is cylindrical, the other end of cover body is uncovered taper shape, two semicircle cover body joint bilateral symmetry are provided with the ear seat, and ear seat center is provided with bolt hole, and two semicircle cover bodies are bolted to connection.
This protective housing is located at the outlet(discharge) flange top of oil circuit, can change hydraulic oil leakage of oil direction, and the pressure when reducing the fluid injection prevents the high pressure oil transverse injection on personnel and equipment, reduces the generation of personal safety and equipment accident; This device is convenient to maintenance management simultaneously, and easy disassembly does not influence the current check work to parts such as flanges.
The enforcement of this scheme: measure the boundary dimension of flange and the interface that will add the protective housing position, make the semicircle cover body of opposite opened; The columned end size of cover body determines that by the flange maximum outside diameter a cone shape end determines according to the oil pipe outside dimension; The cover body both sides are total to two of weld bolt ear seats, and the mode that is connected and fixed of opposite opened cover body is selected bolt for use.
The protective housing that the utility model provides, the beneficial effect that brings: the ejection of fluid level injured the operating personnel after (1) can prevent the leakage of oil of valve platform flange, avoided security incident to take place; (2) prevent that hydraulic oil is ejected into that the operation place is color draws on the ground, can protect the operation field environmental hygiene, can stained corrosion ground and body of wall; (3) improve on-the-spot 5S managerial skills, play promoting effect to promoting this materialization of operation general safety degree level.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right elevation of Fig. 1.
1,2 is cover body among the figure, and 3,4,5,6 is the ear seat, and 7,8 is bolt.
Embodiment
Embodiment:
As shown in Figure 1, 2, a kind of protective housing, comprise cover main body, bolt, described cover main body is made up of two semicircle cover bodies 1,2, cover body 1, an end of 2 are cylindrical, and cover body 1,2 the other end are uncovered taper shape, and two semicircle cover bodies 1,2 joint bilateral symmetry are provided with ear seat 3,4,5,6, ear seat 3,4,5,6 centers are provided with bolt hole, and two semicircle cover bodies 1,2 are by bolt 7,8 fixedly connected.
Concrete making method is: (1) measures the boundary dimension of flange and the interface that will add the protective housing position, makes semicircle opposite opened cover body, and cover body one end size determines that by the maximum outside diameter of flange the other end determines according to the oil pipe outside dimension;
(2) use the thick steel plate of 4mm to make the semicircle cover body of two opposite openeds, cover body left end cylindrical internal diameter size is Φ 100mm, mate with vavle shelf upper flange boundary dimension, flange can be covered fully, cover body right-hand member cylindrical internal diameter size is Φ 50mm, just in time hydraulic steel pipe (Φ 48mm) is wrapped, can mate use.Use welding manner to be made into type;
(3) be used for two of the ear seats of fixing bolt in protective housing cover body both sides welding, the hole is drawn at the center, uses the bolt of M14 * 50mm to be convenient to connect fastening;
(4) the two halves cover body is fastened pipeline and flange, two bolts hole align, and bolt is inserted, and carry out fastening getting final product.
Hydraulic equipment uses extensively at our factory, and pressure is higher relatively, after the protection safety cover is installed at the flange position, though the leakage of oil situation can't be avoided, but can change the fluid injection direction, prevent that high-voltage oil liquid directly is sprayed onto on one's body the personnel, has avoided the security incident generation.
