Description

Pipe orifice clamp for leakage testing and sealing of oil tank

Technical Field

The utility model relates to a technical field of anchor clamps specifically is a mouth of pipe anchor clamps for oil tank leak test is sealed.

Background

The oil tank of a certain type of forklift needs to be tested for leakage after welding, and the sealing plate is usually placed into the oil tank through the oil filling pipe during leakage testing, and then the leakage is tested by pressurization. Inside the closing plate was in the oil tank, whole leak testing process can carry out the leak test to the most welding seam of oil tank, nevertheless can't carry out the leak test to the welding seam of adding oil pipe and oil tank junction, and the leak test is not comprehensive, has the hidden danger.

In the improved leakage test method, the rubber plug is used for sealing the oil filling pipe opening, all welding seams of the oil tank can be covered in the leakage test process, but the rubber plug is used for sealing the oil filling pipe opening, when the leakage test pressure is high, air leakage can be generated at the rubber plug, even the risk of the whole burst of the rubber plug exists, a pipe opening clamp is needed, the rubber plug and a flange of the oil filling pipe opening are clamped tightly, an extra clamping force is provided, the sealing performance of the rubber plug is improved, and meanwhile the risk of the whole burst of the rubber plug is reduced.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a pipe orifice clamp for leakage test sealing of an oil tank, which is applied to the clamping of the leakage test sealing of the oil tank of a certain type of forklift in the forklift industry, has strong universality, large clamping force, single-person operation and high operating efficiency,

the specific technical scheme is as follows: a pipe orifice clamp for leakage test sealing of an oil tank comprises a clamp 1, a U-shaped plate 2 and a pressing plate 3;

the U-shaped plate 2 is horizontally arranged, the U-shaped bayonet is the front part of the U-shaped plate 2, and the lower end surface of the rear part of the U-shaped plate 2 is in threaded connection with a pair of first limiting bolts 21;

the front part of the pressure plate 3 is in threaded connection with an adjusting bolt 31, and the rear part of the pressure plate 3 is in threaded connection with a pair of second limiting bolts 32;

the front end of an upper clamping arm of the clamp 1 is fixedly connected with the middle part of the pressing plate 3 through threads, the upper clamping arm horizontally penetrates through a space between the pair of first limiting bolts 21, the front end of a lower clamping arm of the clamp 1 is fixedly connected with the middle part of the U-shaped plate 2 through threads, and the lower clamping arm horizontally penetrates through a space between the pair of second limiting bolts 32;

when the clamp is clamped, the U-shaped bayonet of the U-shaped plate 2 is clamped on the outer cylindrical surface of the pipe orifice 4 of the oil filling pipe, and the adjusting bolt 31 applies pressure to the rubber plug 41 to enable the rubber plug to be correspondingly plugged in the pipe orifice 4.

Further, the clamp 1 is a Jiagang extrusion type clamp, and the maximum clamping force is 318 kg.

Further, a pair of balance bolts 33 is in threaded connection with the lower end surface of the rear portion of the pressure plate 3 corresponding to the pair of second limit bolts 32, and is used for balancing the force generated when the clamp 1 is clamped.

The utility model has the advantages of as follows:

the utility model discloses a pipe orifice clamp, including clamp, U-shaped plate and clamp plate, the lower terminal surface screw thread at the rear portion of U-shaped plate is connected with a pair of first spacing bolt, the anterior screw thread of clamp plate is connected with adjusting bolt, the rear portion screw thread of clamp plate is connected with a pair of second spacing bolt, therefore the spare part that pipe orifice clamp contains is the standard component most and makes simply and easily and the commonality is strong;

simultaneously, press from both sides tightly during the clamp, the U-shaped bayonet socket card of U-shaped board is established on the outer face of cylinder of the mouth of pipe of adding oil pipe, and adjusting bolt exerts pressure to the rubber stopper, makes it correspond the stopper and establishes in the mouth of pipe, does not need other specialized tools such as spanner, and all operations can be accomplished bare-handed under the no instrument condition, and the labour saving and operation, and clamping-force is big moreover, promotes sealed effect, reduces the whole risk that collapses out of rubber stopper simultaneously.

Drawings

Fig. 1 is a schematic structural view of the pipe orifice clamp of the present invention.

Fig. 2 is a diagram of the usage status of the pipe orifice clamp of the present invention.

Wherein: the clamp comprises a clamp 1, a U-shaped plate 2, a pair of first limit bolts 21, a pressure plate 3, an adjusting bolt 31, a pair of second limit bolts 32, a pair of balance bolts 33, a nozzle 4 and a rubber plug 41.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
