Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in the figures, the pipe hanger in this embodiment includes:
the main body structure 1 comprises two clamping arms 11, the upper parts of the two clamping arms are hinged to a hinge shaft together, the lower parts of the clamping arms 11 are buckled into an arc shape, the tops of the clamping arms 11 are hinged with connecting rods 12, and one ends of the two connecting rods 12, which are far away from the clamping arms 11, are hinged to two sides of a lifting block 13 respectively; an arc-shaped supporting plate 14 is arranged on the inner side of the bottom of the clamping arm 11, and a rubber pad 15 for increasing friction force is arranged on the bottom of the inner side of the arc-shaped supporting plate 14; the connecting rod 12 is hinged on two sides of the hoisting block 13, a guide groove 16 is arranged in the hoisting block 13, a slide rod 17 is fixedly arranged at the top of a common hinge shaft of the two clamping arms 11, and the top of the slide rod 17 is inserted into the guide groove 16 and is in sliding connection with the guide groove;
The pipe hanger integrated configuration of this embodiment includes:
a plurality of the pipe hangers;
coupling assembling 3, coupling assembling 3 is including the connecting rod 31 that is used for connecting each tubular product hoist, connecting rod 31 top is equipped with a plurality of lugs, lift by crane piece 13 and connecting rod 31 fixed connection, be equipped with in the connecting rod 31 and be used for carrying out the interim locking means 32 of locking to slide bar 17, interim locking means 32 includes jack catch 321, jack catch 321 is located the slide bar 17 top, it is equipped with cardboard 322 to slide in the connecting rod 31, cardboard 322 is equipped with breach 323 with the cooperation of jack catch 321, the connecting rod 31 bottom is equipped with the opening that the jack catch 321 of being convenient for stretched into.
Furthermore, a claw 321 is hinged with the sliding rod 17, an elastic part for applying a deflection force to the claw 321 is arranged on the claw 321, and the elastic part is a torsion spring at the hinge shaft of the claw 321 or a spring positioned on one side of the hinge shaft; in addition, the jaw 321 can also be used as an elastic jaw to be fixedly connected with the slide rod 17.
During the use, link to each other lug and hoisting equipment on the connecting rod 31, the handling of tubular product is specifically as follows:
firstly, a pipe lifting appliance combined structure is placed right above a pipe to be conveyed, the combined structure is placed downwards, in the process of placing, under the action of a multifunctional hook 21, the multifunctional hook 21 is naturally separated towards two sides after being contacted with the pipe, so that the clamping arm 11 is opened until the pipe falls into an arc section at the lower part of the clamping arm 11, and the placing is stopped; it should be noted that here too much lowering is to be avoided, which would result in the jaws 321 engaging the catch plates 322;
