Description
Technical field
The present invention relates to safety controls away from equipment technical field, it is more particularly related to which a kind of oxy-acetylene is controlled safely
Away from alarm device.
Background technique
The combustion-supporting gas of oxy-acetylene welding is mainly oxygen, and fuel gas mainly uses acetylene, liquefied petroleum gas etc., by institute
Gas cylinder with storage gas is pressure vessel, gas is flammable explosive gas, is dangerous in all welding methods in this way
Property is one of highest.
Oxygen cylinder and acetylene gas bottle in use should be disposed vertically and be fixed up, and the distance of oxygen cylinder and acetylene gas bottle is not
It obtains and is less than 5m, domestic control oxy-acetylene welding common practice is the trolley for leading to shaping tool at present, prevents oxygen cylinder and acetylene
Gas cylinder is toppled over, but in the construction process, controls deficiency to the safe distance of oxygen cylinder and acetylene gas bottle, there is safety in construction
Hidden danger.
Meanwhile existing logical shaping tool trolley structure is relatively simple, steadily rapidly cannot vertically put bottle body
It sets and fixes；And after bottle body is disposed vertically and is fixed, the integral central of trolley changes, and is easy to happen rollover.
Therefore, need to design a kind of oxy-acetylene safely control away from alarm device to solve the above problem.
Summary of the invention
It is an object of the invention to solve at least the above defect, and provide the advantages of at least will be described later.
It is a further object to provide a kind of oxygen second that early warning can be carried out to the distance of oxygen cylinder and acetylene cylinder
Alkynes weldering safety control is away from alarm device.
It is a further object to provide the heeling conditions that one kind can quickly change bottle body, convenient for the carrying of bottle body
It is controlled away from alarm device safely with the oxy-acetylene welding used.
It is a further object to provide one kind can change center of gravity, guarantees car body balance, prevents the oxygen second toppled over
Alkynes weldering safety control is away from alarm device.
In order to realize these purposes and other advantages according to the present invention, the present invention provide a kind of oxy-acetylene welding safely control away from
Alarm device, wherein including the first car body for loading acetylene cylinder, the second car body for loading oxygen cylinder, for incuding the
The distance-sensor of distance, controller and alarm device between one car body and the second car body: controller is according to distance-sensor
Distance signal control alarm device sounds an alarm, and distance-sensor can be electromagnetic inductor, infrared inductor or other types
Inductor.Distance-sensor is separately mounted on the first car body and the second car body for incuding distance between the two.
Wherein, in order to preferably control bottle body and control distance between the two, to the first car body and the second car body
Structure makes following improvement, the first car body and the second car body construction having the same, and first car body and the second car body wrap
It includes:
Vehicle frame is provided with wheel body below, and artificial promotion can be used in car body, wheel body can also be driven to make with installation of driver
Body movement is obtained, dynamo-electric brake is provided on the vehicle frame, the dynamo-electric brake is for braking the wheel body, in the wheel
Under the support of body, the vehicle frame is in a horizontal state, and vehicle frame, which is in a horizontal state, helps to maintain the whole machine balancing of vehicle frame, the vehicle frame
On be provided with sliding slot, sliding slot is located on the neutrality line above vehicle frame, the sliding slot along the car body length direction be arranged, it is described
Vehicle frame left end is provided with hinge joint；
Support frame, lower end with it is described hinged point articulated, support frame as described above can be swung up and down about hinge joint to change
Heeling condition can be convenient bottle body and place on the support frame, transport or drag convenient for bottle body when support frame is toppled over；Work as support
When frame is upright, bottle body standing upright can be kept, bottle body is facilitated to use；Be provided with arc groove on support frame as described above, acetylene cylinder or
Oxygen cylinder is placed in the arc groove, is matched outside the arc groove and bottle body preferably to contain bottle body, the arc
Any side of slot is hinged with banding part, and the other side of the arc groove is provided with fastener, and the acetylene cylinder is placed on institute
After stating arc groove, the banding part is looped around outside bottle body and with the fastener snapping with by bottle body banding, such structure
So that bottle body is tightly secured on support frame, prevent bottle body from surprisingly toppling over, is pressed onto people.Changed by the heeling condition of support frame,
So that bottle body is kept upright at work, when dragging, keeps inclination to lower the center of gravity, and reduces when trolley pushes bottle body and is easy
The case where overturning inclination.
Gravity block is arranged in the sliding slot, and can move along the chute, and gravity block movement in sliding slot can change
The center of gravity of vehicle frame；Oxygen cylinder and acetylene cylinder gravity are big, and length is big, and center of gravity is very high when erected, do not allow not only to be fixed easily, and hold
Easily topple over, in order to preferably balance the center of gravity of bottle body, setting gravity block moves in sliding slot, when bottle body is upright, the weight of bottle body
Amount is pressed in the left end of vehicle frame, and gravity block is mobile to balance bottle body toward the right at this time, and when bottle body inclination, center of gravity is moved toward vehicle frame middle part
Dynamic, gravity block is also toward movement in the middle part of vehicle frame at this time.
