Technical Field

[0001] The utility model relates to the technical field of pipeline hoisting, in particular to a pipeline hoisting frame suitable for water conservancy construction with different pipe diameters. Background Art

[0002] In water conservancy construction, pipeline hoisting is an important link. The correct hoisting method can ensure construction safety and pipeline integrity. When hoisting the pipeline, slings and hooks are generally used for fixing. The slings are wrapped around the bottom of the pipeline, and then the two ends of the slings are passed through the hooks to ensure that the middle part of the sling is evenly supported on the pipeline. At this time, the hooks can be connected to the lifting equipment, and then the pipeline can be slowly lifted for hoisting.

[0003] Since pipes are generally fixed with slings and hooks during lifting, the slings need to be placed in the center of the pipe when they are wrapped around the pipe. It is also necessary to ensure that the wrapped part of the sling has no kinks and is evenly arranged. Each time the pipe is lifted, the operator generally needs to repeatedly adjust and correct the slings during the wrapping process to ensure the correct position and tightness of the slings, which takes a long time to wrap and fix the pipes. Therefore, we have proposed a pipe lifting frame for water conservancy construction that is suitable for pipes of different diameters. Utility Model Content

[0004] The purpose of the present invention is to provide a pipe lifting frame for water conservancy construction suitable for pipes of different diameters, so as to solve the problem raised in the above background technology that during the winding process, operators generally need to make repeated adjustments and corrections, and it takes a long time to wind and fix the pipes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water conservancy construction pipe lifting frame suitable for different pipe diameters, comprising a lifting plate and a splint one, the support rods on both sides of the lifting plate are movably connected to the splint one and the splint two through bearings, and the inner sides of the splint one and the inner sides of the splint two are respectively bonded with connecting pads, the side of the splint one close to the lifting plate and the side of the splint two close to the lifting plate are respectively fixed to the gear plate through a center rod, and the gear plate is movably connected to the lifting plate through a bearing, the gear plate is connected to the gear plate, and a slide groove one is provided on the side of the lifting plate close to the gear plate, and the gear plate and the slide groove one are slidably connected.

[0006] Preferably, the side of the tooth plate away from the tooth disc is fixed to the slider, and a second sliding groove is provided on the side of the lifting plate close to the slider.

[0007] Preferably, the slider is slidably docked with the second slide groove, and a double-headed screw is passed through the interior of the two sliders.

[0008] Preferably, both ends of the double-headed screw are movably connected to the inner side of the first slide groove through bearings.

[0009] Preferably, one end of the double-headed screw is fixed to the synchronous wheel 1, and the synchronous wheel 1 is movably connected to the lifting plate through a bearing.

[0010] Preferably, the outer side of the synchronous wheel 1 is butted against a synchronous belt, and the middle part of the synchronous belt is butted against a synchronous wheel 2.

[0011] Preferably, guide wheels are movably mounted on one side of the synchronous belt close to the synchronous wheel 1 and the side close to the synchronous wheel 2.

[0012] Preferably, a bevel gear 1 is fixed to one side of the synchronous wheel 2, and the bevel gear 1 is movably connected to the lifting plate through a bearing.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the pipe lifting rack for water conservancy construction is suitable for pipes of different diameters.

A guide wheel is movably installed on one side of the synchronous belt 207 close to the synchronous wheel 1 206, and the bevel gear 1 209 is movably connected to the lifting plate 1 through a bearing, and the bevel gear 1 209 is connected to the bevel gear 2 210, and the bevel gear 2 210 is connected to the lifting plate 1 through a bearing. The transport plate 1 is movably connected, the upper side of the bevel gear 210 is fixed to the knob 211, the connecting pad 103 is made of deformable wear-resistant rubber material, the toothed disc 2 is meshed with the toothed plate 201, the toothed plate 201 matches the slide 1 202, the slider 203 matches the slide 2 204, the slider 203 is threadedly connected to the double-headed screw 205, and the thread directions at both ends of the double-headed screw 205 are in opposite directions, the synchronous wheel 1 206 and the synchronous wheel 2 208 are meshed with the synchronous belt 207, and the bevel gear 1 209 is meshed with the bevel gear 2 210.

[0023] In specific implementation, according to Figures 1-4Water conservancy construction usually involves the development and utilization of water sources, and the pipeline system is used to introduce water from the water source to various water use points. When the pipeline is hoisted, the lifting plate 1 is placed on the upper side of the pipeline, so that the clamping plate 101 and the clamping plate 212 are respectively on both sides of the pipeline. At this time, you can use tools such as an electric wrench to connect with the knob 211, and rotate the knob 211. At this time, the knob 211 can drive the bevel gear 210 to rotate, and the bevel gear 1 209 is meshed with the bevel gear 210, so that the bevel gear 1 209 can rotate with the bevel gear 210. At this time, the bevel gear The first 209 can drive the second synchronous wheel 208 to rotate, and then the first synchronous wheel 206 and the second synchronous wheel 208 are meshed with the synchronous belt 207, so that the second synchronous wheel 208 can simultaneously drive the two first synchronous wheels 206 to rotate through the synchronous belt 207, so that the first synchronous wheel 206 can simultaneously drive the double-headed screw 205 to rotate, and the slider 203 is matched with the second slide 204, so that the slider 203 will not rotate with the double-headed screw 205, and the slider 203 is threadedly connected to the double-headed screw 205, so that the slider 203 can slide stably along the second slide 204. The screw threads at both ends of the double-headed screw 205 are in opposite directions, so that the two sliders 203 passed through the double-headed screw 205 can move away from or approach each other. When the two sliders 203 move away from each other, the slider 203 drives the tooth plate 201 to slide on the upper side of the toothed disc 2.

Clamp 1 101 and clamp 2 102 can be brought close to each other to squeeze and clamp the pipe. At this time, the pipe lifting frame can be quickly restrained together with the pipe to be lifted, and the connecting pad 103 adopts a deformable wear-resistant rubber material to strengthen the friction between clamp 1 101 and clamp 2 102 and the pipe to prevent the pipe from sliding.
