Abstract

The utility model discloses a pipe clasping device applicable to underwater ditching work. The pipe clasping device comprises two parts, namely a supporting frame and a movable arm; the supporting frame consists of a main beam positioned at a middle part and two supporting legs positioned on two sides of the main beam; a suspension head is positioned above the main beam and is fixedly arranged on the main beam; an upper roller wheel is connected and arranged below the main beam; two fixing plates are mounted on two sides of the front part of the main beam; two back connecting legs are fixedly arranged at the back parts of the two supporting legs; a manual hydraulic station is arranged on the right side of the main beam; the movable arm is formed by hinging two oil cylinder small arms and two movable big arms; two lower roller wheels are mounted at the lower parts of the two movable big arms; two side roller wheels are mounted at the inner sides of the two movable big arms; and two emergency rods are mounted at the outer sides of the two movable big arms. The pipe clasping device is powered through the manual hydraulic station and is simple and safe to operate. After hose pipes are clasped at the same time, the hose pipes can only roll between the upper and lower roller wheels and the side roller wheels of the pipe clasping device, and cannot be damaged at all due to the movement of a ditching machine or other emergencies.

Description

A kind of armful pipe unit of ditching operation under water that is applicable to

Technical field

The utility model belongs to the innovation of the ditching servicing unit of pipeline installation under water of ocean engineering field.

Background technology

At present, the trenching machine of ditching operation field employing under water all is to ride over the effect of playing guide-localization and protection pipeline on the underwater line through guide legs on the trenching machine or leading truck.Though the effect that the H type leading truck of the disclosed trenching machine employing of formula trenching machine can play the guiding pipeline is lifted in ZL201020104070.9 contact diving jet spray qi of chong channel ascending adversely; But the sea bottom hose for present fast development but can not play a protective role; Can produce damage potential safety hazards such as distortion, make flexible pipe after ditching construct and can't normally carry out.

Summary of the invention

The purpose of the utility model be at present under water the trenching machine guide legs can not protect underwater hose; And can damage flexible pipe; Can't normally carry out back ditching construction, propose to embrace pipe unit, the guide legs of the alternative trenching machine under water of this device; And be installed on the existing trenching machine, in space among a small circle, be synchronized with the movement and realize the effect of protection flexible pipe and guiding through flexible pipe being taken and limits in one's arms flexible pipe with trenching machine.

It is to embrace pipe unit to comprise bracing frame and movable arm two parts that the utility model solves the technical scheme that its technical problem adopted; Bracing frame is made up of the girder in the middle of being positioned at and two supporting legs that are positioned at the girder both sides; The girder top has outstanding head to be fixed on the girder, and the girder below is connected with upper roller, and the girder front part sides is equipped with two fixed heads; Two supporting leg rear portions are fixed with two rear portion connection legs, and the girder right side is equipped with the hand-hydraulic station; Movable arm is by two oil cylinder forearms and two the big arm of activity hinged compositions, and two the big arm of activity bottoms are equipped with two bottom rollers, and installed inside has two side wheels, and the outside is equipped with two emergency rods.

The beneficial effect of the utility model is to embrace pipe unit and through the hand-hydraulic station power is provided.Dependence manually starts the hand-hydraulic station, does not need extra power, can be operated and realize opening of armful pipe unit and held tightly action by a people, can manually press, lift emergency rod when damaging at the hand-hydraulic station and realize opening and holding tightly function, safety simple to operate.Holding the flexible pipe rear hose simultaneously tightly can only roll embracing between upper and lower roller of pipe unit and the side wheel, can not damage because of trenching machine motion or other emergency case fully.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 embraces pipe unit to embrace the pipe front view;

Fig. 2 embraces the pipe unit lateral view;

Fig. 3 embraces pipe unit bracing frame front view;

Fig. 4 embraces the movable arm front view of pipe unit;

Fig. 5 embraces pipe unit to open figure.

Wherein: the 1-bracing frame; The movable arm of 2-; The 3-flexible pipe; The 4-girder; The 5-supporting leg; 6-hangs head; 7-rear portion connection leg; The 8-fixed head; 9-bearing pin a hole; 10-bearing pin b hole; The 11-upper roller; 12-hand-hydraulic station; The 13-hanger; The 14-pin shaft hole; 15-oil cylinder forearm; The movable big arm of 16-; The 17-bottom roller; The 18-side wheel; The 19-emergency rod; The big pin shaft hole of 20-; 21-small clevis pin with head hole.

The specific embodiment

Shown in accompanying drawing, to embrace pipe unit and be connected and fixed through latch by the big pin shaft hole of pin shaft hole 14 on the girder 4 that is positioned in the middle of the bracing frame 1 and movable arm 2 20, bracing frame 1 is fixed on the trenching machine, and movable arm 2 can rotate around bearing pin.The oil cylinder forearm 15 of movable arm 2 is connected on outstanding 6 of bracing frame 1, oil cylinder forearm 15 flexible can rotations by the big arm 16 of drive activity.When 15 contractions of oil cylinder forearm, movable big arm 16 turns to the position like Fig. 5, and the small clevis pin with head hole 21 of movable big arm 16 is carried out latch with the bearing pin a hole 9 on the fixed head 8 and is connected, and it is locked that the pipe unit open configuration is embraced in realization.When 15 elongations of oil cylinder forearm, movable big arm 16 turns to the position like Fig. 1, and the small clevis pin with head hole 21 of movable big arm 16 is carried out latch with the bearing pin b hole 10 on the fixed head 8 and is connected, and it is locked to realize embracing pipe unit.Be connected to left and right bottom roller 17 closures of movable big arm 16 simultaneously, embrace pipe unit and be the state of holding tightly.Can embrace flexible pipe 3 and carry out ditching operation this moment.

When the flexible pipe ditching operation, embrace pipe unit and be connected to trenching machine rear and front end (front and back be respectively trenching machine advances and rightabout) through latch through the rear portion connection leg 7 that is fixed on the supporting leg 5.Can shackle and wire rope be fixed on the hanger 13, install through loop wheel machine.

Embracing the pipe unit entering is initial open configuration under water.Arrive flexible pipe 3 tops when trenching machine lifts through crane barge with armful pipe unit, flexible pipe 3 entering of slinging this moment are embraced a pipe unit and are embraced in the scope tube.The staff starts hand-hydraulic station 12 or manual and pulls that emergency rod 19 is auxiliary to stretch out oil cylinder forearm 15; Movable big arm 16 turns to as locking behind Fig. 1 position; By upper roller 11, bottom roller 17 and side wheel 18 be limited in very little scope in around the flexible pipe 3 this moment, and flexible pipe 3 is synchronized with the movement and only can produces very little rolling friction and can be owing to move irregular generation distortion or damage of trenching machine with embracing a pipe unit in ditching operation.But the carrying out of ditching operation rapid Continuous can open an armful pipe unit through hand-hydraulic station 12 after ditching is accomplished, and flexible pipe 3 is transferred in the ditch.
