The utility model content
The purpose of this utility model is to solve existing oxygen gun barrel road and metal hose because the oxygen rifle that the syndeton complexity is caused is changed the shortcoming of inefficiency.
For solving the problems of the technologies described above, the utility model provides a kind of oxygen rifle fast replacing device, it comprises oxygen gun body, be connected with described oxygen gun body and be used for fixing oxygen gun body and adjust its lift truck in the vertical direction position height, the water inlet pipe, return pipe and the oxygen lance that are connected with described oxygen gun body, and the water inlet metal hose, backwater metal hose and the oxygen blast metal hose that are connected by flexible coupling with described water inlet pipe, return pipe and oxygen lance respectively; This oxygen rifle fast replacing device also comprises a top connecting plate, a bottom connecting plate and a locking device simultaneously, and described water inlet pipe, return pipe and oxygen lance are integrated on the connecting plate of described top and with oxygen gun body and consist of one; Described flexible coupling is integrated on the connecting plate of described bottom, and is fixed on the described lift truck by support; Described top connecting plate and bottom connecting plate by locking device carry out fastening with separate.
Furthermore, on described water inlet pipe, return pipe and oxygen lance and the corresponding link position of flexible coupling, be respectively arranged with sealing ring between described top connecting plate and the bottom connecting plate.
Furthermore, also be provided with alignment pin between described top connecting plate and the bottom connecting plate.
Adopt oxygen rifle fast replacing device provided by the utility model, have following advantage:
(1) with oxygen rifle water inlet pipe, return pipe and oxygen lance and separately metal hose carry out ways of connecting by flange separately and change into by two modes that connecting plate is integrated and connected up and down, solved the shortcoming that the oxygen rifle is changed inefficiency, improved operating efficiency greatly;
(2) up and down two connecting plates are provided with alignment pin, change the rifle process like this and can realize that oxygen rifle and lift truck locate automatically by alignment pin, do not need artificial the adjustment to align, and have shortened and have changed the rifle time, have improved operating efficiency;
(3) two connecting plates are provided with multiple-sealed circle end face seal and locking device up and down, guarantee can not leak under the pressure of 2.5Mpa between two connecting plates, have effectively strengthened the security of equipment.
Description of drawings
Fig. 1 is the front view of the utility model oxygen rifle fast replacing device.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing preferred implementation of the present utility model is elaborated.
Shown in seeing figures.1.and.2, be respectively the front view and the vertical view of the utility model oxygen rifle fast replacing device.By Fig. 1 and Fig. 2 as can be seen, oxygen rifle fast replacing device of the present utility model comprises oxygen gun body 5, be connected with oxygen gun body 5 and be used for fixing oxygen gun body and adjust its lift truck 12 in the vertical direction position height, the water inlet pipe 1 that is connected with oxygen gun body 5, return pipe 2 and oxygen lance 3, and respectively with water inlet pipe 1, the water inlet metal hose 6 that return pipe 2 and oxygen lance 3 are connected by three flexible couplings 9, backwater metal hose 7 and oxygen blast metal hose 8, this oxygen rifle fast replacing device also comprises a top connecting plate 4, one bottom connecting plate 10 and locking device 15, water inlet pipe 1, return pipe 2 and oxygen lance 3 are integrated on the top connecting plate 4 and with oxygen gun body 5 and consist of one; Three flexible couplings 9 are integrated on the bottom connecting plate 10, and are fixed on the lift truck 12 by support 11; Top connecting plate 4 and bottom connecting plate 10 by locking device 15 carry out fastening with separate.Locking device 15 can adopt the spring locking device, mainly comprises spring, screw rod and locking nut, carries out locking operation by the cooperation with upper member.In the present embodiment, adopted three groups of locking devices altogether, be not limited thereto, also can increase in the specific implementation or minimizing group number but this usefulness is novel.Also be provided with alignment pin 13 between top connecting plate 4 and the bottom connecting plate 10, to realize the quick location of the two.In addition, on water inlet pipe 1, return pipe 2 and oxygen lance 3 and three flexible coupling 9 corresponding link positions, multiple-sealed circle 14 is set respectively between top connecting plate 4 and the bottom connecting plate 10, to realize the sealing of G﹠W separately.In the present embodiment, on the position of water inlet pipe, return pipe, these three pipe correspondences of oxygen lance, be provided with the two seals circle respectively, have six road sealing rings.
Below in conjunction with the concrete course of work oxygen rifle fast replacing device of the present utility model is further detailed: when needing to change the oxygen rifle, only need open the locking device 15 between top connecting plate 4 and the bottom connecting plate 10, hang away old rifle and more renew rifle, water inlet pipe 1, return pipe 2 and the oxygen lance 3 of new rifle are integrated on the top connecting plate 4 and with oxygen gun body 5 and consist of one, and this part can be ready in advance.Multiple-sealed circle 14 is installed again in order to realize the sealing of G﹠W on bottom connecting plate 10.New rifle is under the support of lift truck 12, dock with three integrated on the bottom connecting plate 10 flexible couplings 9, water inlet metal hose 6, backwater metal hose 7 are connected with water inlet pipe 1, return pipe 2 and oxygen lance 3 respectively by these three flexible couplings 9 with oxygen blast metal hose 8.During butt joint, the alignment pin 13 that is provided with between top connecting plate 4 and the bottom connecting plate 10, the quick location that can realize the two.After installation, sealed again locking device 15 can be finished the replacing of oxygen rifle.
