Description

Technical Field

[0001] The utility model relates to the field of construction pipe transportation, in particular to a device used for pipe hoisting and transportation in construction. Background Art

[0002] Publication number CN218909615U discloses a PCCP pipe lifting fixture, including a fixed sleeve, two lifting clamp arms are arranged inside the fixed sleeve, the upper surface of the fixed sleeve is fixedly connected to two support rods, the outer surface of each support rod is slidably connected to a sliding sleeve, a connecting plate is fixedly connected between the two sliding sleeves, and the side surfaces of the two sliding sleeves that are away from each other are movably hinged to a movable pull rod through a first hinge buckle. The device arranges two lifting clamp arms inside the fixed sleeve, and the lifting clamp arms cooperate with the slider and the slide groove in the fixed sleeve, so that the lifting clamp arms can be extended and retracted. Through the extension and retraction of the lifting clamp arms, the movable pull rod drives the slide sleeve to slide under the cooperation of the first hinge buckle and the second hinge buckle, so that it is convenient to unfold the lifting clamp arms and insert them into the pipe. The connecting plate is pulled to slide by the lifting ring and the lifting rod, and the connecting plate drives the two sliding sleeves to slide on the support rod, so that the two lifting clamp arms can hold the two ends of the pipe, so that the pipe will not fall off.

[0003] However, in actual applications, the pipes to be hoisted may be of different lengths or arranged unevenly. Even if the pipes are uniformly long, they cannot be hoisted with a single prior art clamp because the clamping end face of the clamp is shorter than the length of the pipe. At least two prior art clamps are required. However, the prior art does not have the technical feature of fixed-point limiting at the clamping part of the pipe, so it is also inferior to this situation. Moreover, if the clamped pipes are of different lengths, the shorter pipes will tend to move sideways to release the force during the clamping process. Such short pipes will be at risk of falling when hoisted. The clamping capacity of the prior art clamp comes from the gravity of the heavy object. When the clamp is temporarily suspended without being affected by the heavy object, it will affect the clamping of the clamp. A spring is provided between the two hoisting clamp arms in the clamp fixing sleeve. The spring is compressed in the clamping state. The compressed spring releases the spring compression force when the clamp is temporarily suspended without being affected by the heavy object, causing the clamp arm to pop open, thereby causing the heavy object in the clamp arm to fall, which poses a considerable risk.

[0036] The use principle of this utility model:

[0037] When some pipes of different lengths need to be hoisted, packed and taken away in an industrial or construction site, the staff will stack these pipes in the same position, and then move the main hoisting component 1, telescopic component 3 and side stop component 4 of the equipment to the side of the pipes to be transported, place multiple main hoisting components 1 at a certain interval, place side stop components 4 at both ends of the longest pipe, and after the components that can clamp the pipes are distributed and placed, place the pipes in the clamping arm 15 of the main hoisting component 1 close to the ground, and then connect the main hoisting component 1 and side stop component 4 that have been arranged on the pipes through the telescopic component 3, and reinforce the connection position between one end of the telescopic component 3 and the connecting component through the connecting fixing component 2, such as Figure 1 As shown, the above-mentioned connecting assembly refers to the main hanging assembly 1 or the side stop assembly 4, that is, the two ends of the telescopic assembly 3 can be two main hanging assemblies 1 or one main hanging assembly 1 and one side stop assembly 4, because the device is modularly assembled, such as Figure 1 As shown, the main hanging assembly 1 should clamp the pipe at multiple points, and telescopic assemblies 3 are distributed between the main hanging assemblies 1 to support the two main hanging assemblies 1 and limit the position of the two main hanging assemblies 1 clamping the pipe. Figure 4 As shown, the connecting and fixing components 2 are distributed at both ends of the telescopic component 3, as shown in FIG. Figure 5 As shown, whenever the telescopic assembly 3 is connected to the main suspension assembly 1 or to the side stop assembly 4, the connecting and fixing assembly 2 is used for reinforcement;

[0038] Pass multiple lifting ropes through the lifting rings 13 of multiple main lifting components 1 and the eye rods 423 of the side block components, such as Figure 1 As shown, the lifting device is tightened while the clamping arm 15 of the main lifting component 1 is extended to extend the blocking plate 43 of the side block component. After the tightened clamping arm 15 clamps the pipe fitting, the weight of the pipe fitting and the device will make the two clamping arms 15 of the main lifting component fit tightly together, and the two ends of the pipe fitting will not fall off due to the obstruction of the side block component 4 and its blocking plate 43. The staff will clamp the buckle 5 into the through hole on the lower side of the clamping arm 15 to fix the two clamping arms 15. The staff will pack and bundle the batch of pipes of different lengths with packing tape, and then the lifting device at the site will lift the device and the pipe fittings together through the lifting rope to transport these pipes of different lengths to another place.

[0039] After arriving at another site, the device is still some distance from the ground when the pipes are put down. Figure 1 As shown, the buckle 5 on the clamping arm 15 of the main hanging assembly 1 is pulled out, and the clamping arm 15 will not pop open due to the weight of the pipe and the device body. Then, the device is placed on the ground together with the clamped pipe, the hanging rope is pulled out, and the side stop assemblies 4 on both sides of the device are retracted, as shown in FIG. Figure 3As shown, the blocking plate 43 will be retracted into the fixed shell under the action of the staff and the return spring Ⅰ44 in the side block assembly, and the side block assemblies 4 on both sides will be removed. Figure 4 As shown, press the hoisting plates 12 one by one and pull open the clamping arms 15 to loosen the clamping arms 15 and remove the telescopic assembly 3 and the main hoisting assembly 1 until the device is completely disassembled and away from the packaged pipes, completing the hoisting and transportation of the pipes.
