Detailed implementation manners

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] Embodiment 1: As Figure 1 , Figure 2 shown, an auxiliary hoist for installing a water pump pipeline includes a hoisting pipe 1, a hanger 2, a bottom plate 3 and a sliding sleeve 4.

[0018] As Figure 1 , Figure 2 shown, the hoisting pipe 1 is arranged in a vertical tubular shape, and the middle position of the hoisting pipe 1 is provided with a mounting hole 11 in a T shape. The mounting hole 11 is for the pipeline and the flange on the pipeline to be horizontally inserted. The hanger 2 is arranged at the upper end of the hoisting pipe 1 and is used for connecting a suspension cable.

[0019] As Figure 1 , Figure 2 shown, the bottom plate 3 is horizontally arranged at the lower end of the hoisting pipe 1, and the outer edge extends outward. The bottom plate 3 is provided with a notch 31 that communicates with the lower end of the mounting hole 11 and is for the pipeline to be inserted. The sliding sleeve 4 is vertically slidably connected to the outer wall of the hoisting pipe 1 and falls on the outer edge of the bottom plate 3 and is used to cover the mounting hole 11. The inner side wall of the sliding sleeve 4 is provided with balls 41 that abut against the outer wall of the hoisting pipe 1 to realize the smooth sliding of the sliding sleeve 4.

[0020] As Figure 1 , Figure 2 shown, the two ends of the hanger 2 extend downward to be provided with guiding strips 21, and the sliding sleeve 4 is provided with guiding holes 42 for the guiding strips 21 to be inserted, so as to limit the vertical sliding of the sliding sleeve 4 along a preset direction and make the mounting hole 11 always stably aligned with the notch 31.

[0021] When it is necessary to hoist the pipeline, the pipeline is erected, and then the sliding sleeve 4 is controlled to slide upward to open the mounting hole 11, and then the hoisting pipe 1 is controlled to move horizontally, so that the pipeline and the flange above the pipeline pass through the mounting hole 11 and the notch 31 and then enter the hoisting pipe 1.

[0022] Then control the sliding sleeve 4 to slide downward, so that the sliding sleeve 4 covers the mounting hole 11 and drops onto the bottom plate 3. At this time, the pipeline is in a closed space, and then the hanger 2 and the lifting pipe 1 can be hoisted. The flange on the pipeline is clamped by the bottom plate 3 to realize the hoisting of the pipeline.

[0023] Then place the pipeline above the pipeline to be installed and fix the pipeline. Then control the lifting pipe 1 to lower, open the sliding sleeve 4, and then control the lifting pipe 1 to slide horizontally, so that the upper end of the pipeline slides out along the mounting hole 11 and the notch 31 to complete the unloading operation of the lifting pipe 1.

[0024] Therefore, by setting the lifting pipe 1 with the mounting hole 11, the pipeline and the flange at the upper end of the pipeline can be quickly inserted into the lifting pipe 1, and the mounting hole 11 is covered by the sliding sleeve 4, so that the pipeline can be quickly installed into the lifting pipe 1 to realize the quick hoisting of the pipeline. And after hoisting, the sliding sleeve 4 can be quickly lifted to realize the quick disassembly of the pipeline, so as to realize the quick hoisting and installation of the pipeline and improve the installation efficiency.

[0025] Embodiment 2: As Figure 3 、 Figure 4 shown, sliding rods 5 are vertically penetrated through both sides of the bottom plate 3. A pressing plate 51 is horizontally arranged at the upper end of the sliding rod 5, and the upper end surface of the pressing plate 51 is located below the horizontal section position of the mounting hole 11. A baffle 52 is arranged at the lower end of the sliding rod 5, and a tension spring 53 is sleeved on the outer wall of the sliding rod 5 between the bottom plate 3 and the baffle 52.

[0026] As Figure 3 、 Figure 4 shown, a connecting rod 54 is arranged between the lower end of the sliding rod 5 and the sliding sleeve 4 for driving the sliding sleeve 4 to slide synchronously when the sliding rod 5 slides. A triangular bracket 55 for abutting against the ground is arranged at the lower end of the connecting rod 54 for stably placing the entire lifting tool on the ground for storage.

[0027] As Figure 3 、 Figure 4 shown, a retaining ring 12 is arranged on the inner wall of the lifting pipe 1 above the mounting hole 11, and the lower end surface of the retaining ring 12 is flush with the top wall of the horizontal section position in the mounting hole 11.

[0028] As Figure 3 、 Figure 5 shown, a groove 13 is arranged at the middle position of the horizontal section position in the mounting hole 11. A limiting plate 14 is rotatably connected to the outside of the groove 13, and a torsion spring 15 is arranged at the rotating position. The lower end surface of the limiting plate 14 is flush with the top wall of the horizontal section position in the mounting hole 11, and the limiting plate 14 is flipped and inserted into the mounting hole 11.

[0029] When there is no pipeline in the hoisting pipe 1, the tension spring 53 controls the sliding rod 5 to slide upward. At this time, the sliding rod 5 drives the connecting rod 54 and the sliding sleeve 4 to move upward synchronously. The sliding sleeve 4 is located above the mounting hole 11, and the position of the pressing plate 51 on the sliding rod 5 is below the horizontal section position in the mounting hole 11. At the same time, the torsion spring 15 drives the limiting plate 14 to turn outward and be in a horizontal state, and it is flush with the bottom wall of the horizontal section position in the mounting hole 11.

[0030] When hoisting the pipeline, control the hoisting pipe 1 to approach the pipeline, so that the limiting plate 14 presses above the flange at the upper end of the pipeline. Then control the hoisting pipe 1 to move horizontally, so that the flange at the upper end of the pipeline automatically enters the mounting hole 11 under the guiding action of the limiting plate 14.

[0031] Then control the hoisting pipe 1 to move upward. At this time, under the drive of the self-weight of the pipeline, it will press the pressing plate 51 and the sliding rod 5 to move downward. The sliding rod 5 drives the connecting rod 54 and the sliding sleeve 4 to move downward synchronously. Until the pressing plate 51 abuts against the upper end face of the bottom plate 3, the sliding sleeve 4 covers the mounting hole 11, realizing the closing of the mounting hole 11, and the sliding sleeve 4 presses the limiting plate 14 to turn over and embed into the mounting hole 11. Then the pipeline can be hoisted and installed.

[0032] When the pipeline is installed, control the hoisting pipe 1 to lower, so that the pipeline abuts against the retaining ring 12 on the inner wall of the hoisting pipe 1. At this time, the tension spring 53 pulls the sliding rod 5 to move upward. The sliding rod 5 drives the connecting rod 54 and the sliding sleeve 4 to move synchronously, so that the sliding sleeve 4 is located above the mounting hole 11, realizing the opening of the mounting hole 11.

[0033] Subsequently, under the action of the torsion spring 15, the limiting plate 14 is turned outward to a horizontal state. Then control the hoisting pipe 1 to slide horizontally. Under the guiding action of the retaining ring 12 and the limiting plate 14, the pipeline smoothly passes through the mounting hole 11 and the notch 31, realizing the automatic loading and unloading of the hoisting pipe 1 without manual intervention, improving the hoisting convenience.

[0034] As Figure 4 shown, an alarm 16 is provided on the outer wall of the hoisting pipe 1, and a push-button switch 32 for the pressing plate 51 to press is provided on the upper end face of the bottom plate 3. Therefore, when the hoisting pipe 1 hoists the pipeline, the pressing plate 51 automatically presses the push-button switch 32, making the alarm 16 sound to warn the on-site workers and ensuring the safety during hoisting.

[0035] The specific embodiments are only explanations of the present invention, and they are not limitations to the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
