Description
Technical Field
The utility model belongs to the field of municipal water supply and drainage construction, and particularly relates to pipeline hoisting equipment.
Background
In municipal administration water supply and drainage pipeline work progress, relate to the installation of lifting by crane the level to major diameter pipeline section. Usually, a hanging belt or a steel wire rope bundle is adopted for binding and hanging, the hanging belt is easy to slide in the hanging process, the safety is poor, and the binding and unbinding processes of the pipeline are complex and the efficiency is low.
Patent CN111977508A discloses a pipe fitting handling mobile device, and it includes two clamping parts, and every clamping part is partly arc, and another part is straight arm handle, and through the round pin hub connection, two arc parts hold the pipeline relatively in the middle of the straight arm handle of two clamping parts, and the loop wheel machine is lifted by crane through hoist rope connection two straight arm handle tip. The device has higher hoisting efficiency than a binding mode, but when in construction, one pipeline section needs to be clamped by two devices, if two cranes are adopted for hoisting, the two cranes have higher coordination operation difficulty, and the air balance is not easy to control; if one crane is adopted to connect two devices simultaneously through a lifting rope, the two devices easily slide relatively, and certain potential safety hazards exist.
Disclosure of Invention
The utility model aims to solve the problems and provide a self-locking type large-diameter pipeline hoisting device which is used for hoisting a pipeline section by one device, ensuring that the pipeline is balanced in the hoisting process and improving the safety.
The technical scheme of the utility model is as follows:
a self-locking type large-diameter pipeline hoisting device is characterized in that: comprises two clamps and a movable lifting lug; each clamp comprises two clamping rods, the lower half part of each clamping rod is an arc clamping section, the upper half part of each clamping rod is a straight arm section, the middle parts of the straight arm sections of the two clamping rods are rotationally connected through a pin shaft, the intrados of the two arc clamping sections are opposite, the upper end of the straight arm section of each clamping rod is respectively connected with a dowel, the lower end of each dowel is rotationally connected with the upper end of the straight arm section of each clamping rod through a pin shaft, and the circular arc diameter of each arc clamping section is consistent with the outer diameter of a pipeline to be hoisted; the clamping rods of the two clamps are oppositely arranged in parallel and have a certain distance, an arc clamping plate is welded between the arc clamping sections of the clamping rods opposite to each other, and the radian of the arc clamping plate is consistent with that of the arc clamping sections; the movable lifting lug is an isosceles triangle, the bottom edge of the movable lifting lug is welded with a shaft lever, two ends of the shaft lever extend out of two ends of the bottom edge of the lifting lug by a certain length respectively and are connected with the upper ends of two dowel bars connected with each clamp in a rotating mode respectively, and a lifting hole is formed in the position, close to the top angle, of the movable lifting lug.
According to the utility model, the two clamps are connected through the arc clamping plate, the two clamps and the arc clamping plate jointly lock the pipeline, one device can hoist one pipeline section, the arc clamping plate can increase the contact area between the device and the pipeline, the pipeline is effectively protected, the balance and stability of the pipeline in the hoisting process are ensured, and the construction efficiency and the safety are high.

Detailed Description
As shown in fig. 1 and 2, the utility model comprises two clamps and a movable lifting lug; each clamp comprises two clamping rods 1, the lower half part of each clamping rod is an arc-shaped clamping section 11, the upper half part of each clamping rod is a straight arm section 12, the straight arm sections 12 of the two clamping rods are connected in a rotating way through a pin shaft 2, the intrados of the two arc-shaped clamping sections are opposite, the upper end of the straight arm section of each clamping rod 1 is respectively connected with a dowel bar 3, the lower end of each dowel bar 3 is connected with the upper end of the straight arm section 12 of the clamping rod in a rotating way through a pin shaft, and the arc diameter of each arc-shaped clamping section is consistent with the outer diameter of a pipeline to be hoisted; the clamping rods of the two clamps are oppositely arranged in parallel and have a certain distance, an arc clamping plate 4 is welded between the arc clamping sections 11 of the clamping rods opposite to each other, and the radian of the arc clamping plate 4 is consistent with that of the arc clamping sections 11; the movable lifting lug 5 is an isosceles triangle, the bottom edge of the movable lifting lug is welded with a shaft rod 51, two ends of the shaft rod 51 extend to a certain length outside two ends of the bottom edge of the lifting lug respectively and are connected with the upper ends of the two dowel bars 3 connected with each clamp in a rotating mode, and a lifting hole 52 is formed in the position, close to the top angle, of the movable lifting lug.
In the concrete implementation of the utility model, in order to prevent the pipeline from sliding during lifting, rubber cushion layers can be adhered to both the arc-shaped clamping section of the clamping rod and the inner cambered surface of the arc-shaped clamping plate.
When the pipeline locking device is used, the arc-shaped clamping sections of the clamping rods of the two clamps and the two arc-shaped clamping plates are respectively arranged at two sides of the middle of the pipeline, the crane is connected with the movable lifting lug through the lifting rope to lift upwards, the two clamps are tightened through the dowel steel, the pipeline can be automatically locked, and the greater the weight of the pipeline is, the more firm the locking is; the contact surface and friction force between the two arc clamping plates and the pipeline can be increased, so that the pipeline is prevented from sliding; the movable lifting lug is of a rigid structure, so that the balance and stability of the pipeline in the air can be ensured. After lifting in place, the lifting rope is loosened, and the clamp is automatically unlocked.
