Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction, in particular to a pipeline transporting device. Background Art

[0002] Pipeline construction is an indispensable project in urbanization construction. Pipeline engineering is responsible for the city's water supply, heating, network supply, power supply, and sewage transportation. Since each pipeline is like a line, it has its own direction and angle, and is also called pipeline engineering.

[0003] In pipeline construction, you first need to dig a foundation pit according to the established markings, then bury the pipeline inside the foundation pit, and finally backfill the foundation pit. During the pipeline construction process, the pipeline needs to be transported, so a transport device is needed.

[0004] Among them, a search found that there is an application number CN202322946278.5 for a pipe handling device. The utility model can clamp the pipe placed on the ground by two arc-shaped clamping frames, and fix the pipe at three points with a limit frame. At the same time, the clamped and fixed pipe can be lifted by a lifting mechanism. The above method can avoid manual handling of the pipe and then placing it on the device, thereby improving the safety of the device during use. At the same time, lifting the pipe by the threaded rod structure is more labor-saving. Among them, the shortcomings are as follows:

[0005] Since composite sewer pipes are generally composed of multiple layers, the thickness is generally between 2-3CM, the length is between 6-8M, and they are heavy, they require safer and more stable carrying and transportation. After the pipes are transported, they are placed on the ground. There is a lack of a buffer mechanism, which causes additional impact between the pipes and the ground. At the same time, when the pipes are stacked for a long time, the soil acts as an adhesive to bond the pipes to the ground, and they need to be pried before they can be transported. Therefore, it is necessary to improve the existing mechanism and design a new type of transporting device. Utility Model Content

A notch is provided along the opening of the shovel plate 6, and the notch is plug-in connected to the slider 503, and a slot is provided between the shovel plate 6 and the slider 503. The shovel plate 6 is connected to the slider 503 by a latch, and the shovel plate 6 can be plugged into the guide column 502, and then the latch is inserted into the slot to lock the shovel plate 6 and the guide column 502. The rotating shaft surfaces on both sides of the anti-slip plate 601 are penetrated by The connecting holes are also provided on the surface of the shaft groove of the shovel plate 6. When the angle between the anti-slip plate 601 and the ground is 0° and 65°, the connecting holes on the rotating shaft correspond to the connecting holes on the shaft groove. The connection is made through the pin to push the cart 1 to move, and the anti-slip plate 601 is inserted between the pipeline and the ground until the buffer slide 4 contacts the pipeline. Then the pin on the shaft groove of the shovel plate 6 is pulled out, and the anti-slip plate 601 is adjusted to 65°. Then the pin is inserted to lock the anti-slip plate 601. Then, the first hydraulic rod 201 is controlled to retract, and the buffer slide 4 acts on the pipeline. In conjunction with the limit of the anti-slip plate 601, the pipeline is pried up by the lever principle to create a gap between it and the ground, thereby achieving the purpose of threading the rope. This setting can ensure the safety and convenience of construction.

[0033] Reference Figure 1-5 , a limiting component that can fix the pipeline is provided in the middle of the upper part of the cart 1;

[0034] The limiting assembly includes: a load-bearing plate 2, a first hydraulic rod 201, a rotating column 202, a pipe limiting plate 3, a reserved opening 301, a pipe unloading push plate 302, a fixed pulley 303, a buffer slide 4, a pulley 401, and a hanging ring 402; the load-bearing plate 2 is fixedly installed on the upper middle part of the cart 1, one side of the load-bearing plate 2 is rotatably connected to the first hydraulic rod 201, and the other side of the load-bearing plate 2 is fixedly installed with the rotating column 202. The end of the rotating column 202 and the movable end of the first hydraulic rod 201 are both rotatably connected to the limit plate 3 through a rotating shaft, and one side of the limit plate 3 is rotatably connected to the fixed pulley 303;

[0035] The middle part of the limiting plate 3 is a recessed "U" shape, and a reserved opening 301 is provided at the recessed position of the limiting plate 3. A pipe unloading push plate 302 is rotatably connected to the recessed position of the limiting plate 3. The pipe unloading push plate 302 has the same arc as the "U"-shaped recess on the pipeline limiting plate 3. A buffer slide 4 is extended from the other side of the limiting plate 3. The surface of the buffer slide 4 is rotatably connected to a pulley 401. The surface of the buffer slide 4 is located between the pulleys 401 and is integrated with a hanging ring 402 through a groove.

[0036] Furthermore, a second hydraulic rod 7 is fixedly installed on one side of the load-bearing plate 2 above the cart 1, and there are two of them. The top of the second hydraulic rod 7 is rotatably connected to a roller, and there are also two reserved openings 301 and pipe unloading push plates 302. When the buffer slide 4 is tilted, the reserved opening 301 is set corresponding to the second hydraulic rod 7. When the pipeline needs to be unloaded, the first hydraulic rod 201 is controlled to extend so that the end of the buffer slide 4 contacts the ground, and then the second hydraulic rod 7 is controlled to extend. The telescopic end of the second hydraulic rod 7 brings the roller into contact with the pipe unloading push plate 302. At this time, the pipe unloading push plate 302 tilts under the action of the rotating shaft, and the pipeline leaves the pipe unloading push plate 302 due to gravity. The rope on the winch 103 passes between the two pipe unloading push plates 302 to avoid conflict. This setting serves as a buffer setting, making the entire pipeline safer when unloading the pipe and avoiding damage to the operators caused by the rolling of the pipeline.

[0037] Furthermore, there are several pulleys 401 , which are arranged in two rows, and the hanging ring 402 is located between the two rows of pulleys 401 . The pulleys 401 can reduce the friction of the pipeline when it moves.

[0038] Furthermore, the slider 503 is threadedly engaged with the screw rod 501, and the slider 503 is slidingly arranged with the guide column 502. A handle is provided on the top of the screw rod 501, and the handle extends out of the groove 5. By rotating the screw rod 501, the screw rod 501 thread engages with the slider 503 to move, and the guide column 502 guides the slider 503, thereby achieving the purpose of adjusting the horizontal height of the shovel plate 6.

[0039] Furthermore, the hydraulic station 102 and the winch 103 are both electrically connected to an external power supply, and are equipped with a control panel to control the hydraulic station 102 and the winch 103. The hydraulic station 102 can control the extension and retraction of the first hydraulic rod 201 and the second hydraulic rod 7.

[0040] Working principle: First, two or two devices work at the same time. According to the bonding condition of the pipeline and the ground, choose whether to install the shovel plate 6. When the gap between the pipeline and the ground is small, the shovel plate 6 can be plugged into the guide column 502, and then the pin is inserted into the slot to lock the shovel plate 6 and the guide column 502. At this time, the first hydraulic rod 201 is extended by controlling the hydraulic station 102, and the pipeline limit plate 3 is rotated under the action of the bearing column 202, so that the buffer slide 4 is tilted, and then the screw rod 501 is rotated to make the screw rod 501 thread engage the slider 503 to move, and the guide column 502 guides the slider 503, thereby achieving the purpose of adjusting the horizontal height of the shovel plate 6, and then push the cart 1 to move, and the anti-slip plate 601 is inserted between the pipeline and the ground until the buffer slide 4 contacts the pipeline, and then the shovel plate is moved. Pull out the pin on the 6-axis slot, adjust the anti-slip plate 601 to 65°, then insert the pin to lock the anti-slip plate 601, and then control the first hydraulic rod 201 to retract, the buffer slide 4 acts on the pipeline, cooperate with the anti-slip plate 601 to limit the pipeline, use the lever principle to pry up the pipeline, and create a gap between it and the ground. At this time, pass the rope head of the winch 103 around the fixed pulley 303 and the pipeline, and finally connect it to the hanging ring 402 through the fastener. Finally, control the first hydraulic rod 201 to extend, so that the end of the buffer slide 4 contacts the shovel plate 6, and then, through the rotation of the roller of the winch 103, the rope is wound, and then the pipeline is pulled along the buffer slide 4 until the pipeline moves to the pipe unloading push plate 302, and the pulley 401 can reduce the friction. Then, the pipeline limit plate 3 is controlled to be parallel to the horizontal plane by the first hydraulic rod 201;

[0041] When the gap between the pipeline and the ground is normal, or the soil is soft, the shovel plate 6 can be removed from the slider 503, and the rope end of the winch 103 can be directly passed around the fixed pulley 303 and the pipeline, and finally connected to the hanging ring 402 through the fastener, and the winch 103 can be used to pull the pipeline onto the pipeline limit plate 3, which is more labor-saving, convenient and safe to operate;

[0042] When the pipeline needs to be unloaded, the first hydraulic rod 201 is controlled to extend so that the end of the buffer slide 4 contacts the ground, and then the second hydraulic rod 7 is controlled to extend. The telescopic end of the second hydraulic rod 7 brings the roller into contact with the pipe unloading push plate 302. At this time, the pipe unloading push plate 302 tilts under the action of the rotating shaft, and the pipeline leaves the pipe unloading push plate 302 due to gravity. At this time, the winch 103 also starts to slowly release the rope. The rope on the winch 103 passes between the two pipe unloading push plates 302 until the pipeline contacts the ground. This setting serves as a buffer setting, making the entire pipeline safer when unloading the pipe and avoiding damage to the operators caused by the rolling of the pipeline.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
