Description

Technical Field

[0001] The utility model relates to the technical field of pipeline transportation, in particular to a municipal cement pipeline laying device. Background Art

[0002] Municipal cement pipes are pipes made of cement as raw material. They are large in size and heavy in weight. During the construction process, a large number of cement pipes often need to be laid, and on-site personnel need to use lifting equipment to lift the pipes to the pre-buried position.

[0003] The existing pipeline laying device grabs and clamps the cement pipe by setting symmetrical clamps. However, during use, since the clamps can only clamp part of the outer circumference of the cement pipe, if the clamping force of the clamps is too large, it will cause damage to the cement pipe. If the clamping force is too small, the cement pipe cannot be fixed and clamped, which will affect the stability of the cement pipe during transportation. During the application process, sometimes, on-site personnel will use nylon belt lifting method. However, nylon belt lifting has limited load-bearing capacity on the one hand and is easy to wear on the other hand. In addition, after the cement pipe is placed, the extraction process is also more laborious, and it is easy to cause the cement pipe to roll with the nylon belt and be misplaced. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that the pipe laying device grabs and clamps the cement pipe during use by setting symmetrical claws, but the cement pipe transportation is affected due to excessive or insufficient clamping force, thereby providing a municipal cement pipe laying device.

[0005] In order to solve the above problems, the utility model provides a municipal cement pipeline laying device, comprising:

[0006] A chain belt, wherein the chain belt is formed into a loop and is suitable for enclosing the cement pipe;

[0007] A rolling assembly, wherein the rolling assembly is arranged on the chain belt, the rolling assembly is provided with a rolling member, and the rolling member contacts the outer peripheral surface of the cement pipe;

[0008] A lifting assembly includes a lifting block. In a hoisting state, the lifting block is connected to both ends of a chain belt.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1-7 A specific implementation of the municipal cement pipeline 2 shown includes: a lifting component 1, two chain belts 3, and a plurality of rolling components 4 arranged on each chain belt 3.

[0042] like Figure 1-4 As shown, the lifting assembly 1 includes a lifting frame 104, and the lifting frame 104 is provided with four vertical plates 102, that is, the four vertical plates 102 are arranged at intervals. The lifting frame 104 is provided with a hoist 101, a hoist shaft 103 and a hoist belt 105, wherein the hoist shaft 103 is arranged along the length direction of the lifting frame 104, the hoist 101 is arranged at one end of the hoist shaft 103, and the hoist shaft 103 is provided with two hoist belts 105 facing the ground, and the two hoist belts 105 are arranged at intervals along the length direction of the hoist shaft 103, and a lifting block 106 is provided at one end of each hoist belt 105 away from the hoist shaft 103. Figure 3 As shown, each lifting block 106 is provided with a "U"-shaped accommodation space 1061, and two card slots 1062 are respectively provided on the plates on both sides of the accommodation space 1061. Figure 1 , Figure 2 and Figure 4 As shown, the lifting assembly 1 further includes two lap plates 107. A lap plate 107 is provided between two adjacent vertical plates 102, and the length direction of the lap plate 107 is perpendicular to the length direction of the lifting frame 104. The lap plate 107 is detachably connected to the vertical plate 102. To prevent the lap plate 107 from shaking arbitrarily, as shown in FIG. Figure 2 As shown, each vertical plate 102 is provided with a bottom plate 110 at the bottom, and two clamping blocks 109 are provided on the upper surface of the bottom plate 110. The two clamping blocks 109 are provided on both sides of the vertical plate 102, and the lap plate 107 is accommodated between the two clamping blocks 109. Figure 1 , Figure 2 As shown, a rotating wheel 108 is respectively disposed on the lower surface of each vertical plate 102 , and the rotating wheel 108 is used to drive the lifting frame 104 to move.

[0043] like Figure 5 , Figure 6 and Figure 7As shown, the chain belt 3 is provided with a plurality of rolling assemblies 4, and adjacent rolling assemblies 4 are arranged at intervals, and each rolling assembly 4 includes a rotating shaft 402 and three rolling elements 401, wherein the length direction of the rotating shaft 402 is perpendicular to the length direction of the chain belt 3, the rotating shaft 402 is rotatably connected with the chain belt 3, and the rolling element 401 is sleeved on the outer peripheral surface of the rotating shaft 402, and the rolling element 401 is rotatably connected with the rotating shaft 402, and the rolling element 401 is suitable for contacting the outer peripheral surface of the cement pipe 2. Specifically, the rolling element 401 is a roller, and the rolling element 401 and the rotating shaft 402 are made of metal. Figure 7 As shown, each end of each rotating shaft 402 is provided with an inner piece 304 and an outer piece 305, and the rotating shaft 402 is rotatably connected to the inner piece 304 and the outer piece 305, that is, one end of a rotating shaft 402 is rotatably connected to an inner piece 304 and an outer piece 305, respectively. It should be noted that both ends of the same inner piece 304 are connected to the outer piece 305 through the rotating shaft 402, and both ends of the same outer piece 305 are connected to the inner piece 304 through the rotating shaft 402 to form a chain belt 3. Specifically, the inner piece 304 and the outer piece 305 are both made of metal. Figure 5 , Figure 6 As shown, a clamping plate 301 is provided at each end of the chain belt 3, and the clamping plate 301 is rotatably connected to the inner plate 304 or the outer plate 305. The clamping plate 301 is provided with a clamping end 302, and the clamping end 302 is adapted to the clamping slot 1062 of the lifting block 106. Figure 5 As shown, it also includes a one-way slide plate 303, which is provided with a rotating end, and the rotating end is rotatably connected to the two ends of the rotating shaft 402, and the one-way slide plate 303 is set in a one-to-one correspondence with the rotating shaft 402, and the one-way slide plate 303 has the same direction. By setting the same direction, it is easy for the chain belt 3 to slide in one direction along the length direction and difficult to slide in the other direction along the length direction, that is, the one-way slide plate 303 allows the chain belt 3 to be drawn out in only one direction, and the one-way slide plate 303 can also protect the rolling element 401 and the chain belt 3 of the rolling assembly 4, so as to prevent the chain belt 3 and the rolling element 401 from directly contacting the ground, and to prevent the rolling element 401 from rolling in the opposite direction. Specifically, the one-way slide plate 303 is made of stainless steel.

[0044] In order to realize automatic control, a remote controller is also included, and the remote controller is connected to the winch 101 for communication.

[0045] During the specific implementation process, the on-site personnel place the lifting frame 104 above the cement pipe 2, place the chain belt 3 on the outer peripheral surface of the cement pipe 2, and make the rolling element 401 contact with the cement pipe 2. The chain belt 3 forms a ring to enclose a certain section of the cement pipe 2. The remote control controls the winch 101 to rotate and drive the winch belt 105 to move downward to a preset height. The two snap-in plates 301 of the same chain belt 3 are placed in the "U"-shaped accommodating space 1061, and the snap-in end 302 of the snap-in plate 301 is placed in the snap-in groove 1062 of the lifting block 106. The winch 101 is controlled to drive the winch belt 105 to rise slowly, so that the cement pipe 2 rises slowly. After the cement pipe 2 is completely raised, the lap plate 107 is placed between the two vertical plates 102, and the lifting frame 104 is pushed to move the rotating wheel 108 toward the laying position. When encountering a groove, the lap plate 107 is removed and placed on the groove, and the rotating wheel 108 is pushed to cross the groove through the lap plate 107 until the lifting frame 104 moves to the laying position. After the cement pipe 2 moves to the laying position, the chain belt 3 is slowly pulled out. Due to the rolling contact between the cement pipe 2 and the rolling element 401, the cement pipe 2 will not roll during the chain belt 3 pulling process, thereby protecting the cement pipe 2.

[0046] As an alternative implementation, the rolling element 401 may also be a ball.

[0047] As an alternative embodiment, the number of the hoisting belts 105 may be 1, 3 or even more.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
