Description

Technical Field

[0001] The utility model relates to the field of cast iron pipe hoisting devices, in particular to a convenient-to-use cast iron pipe hoisting device. Background Art

[0002] Cast iron pipe is a pipe cast in cast iron. It is used for water supply, drainage and gas transmission pipelines.

[0003] Cast iron pipes are relatively heavy and thus require lifting equipment for lifting and moving. However, when lifting them, some people directly hang hooks on both ends of the cast iron pipes, which reduces the safety of lifting. Some people tie them on both ends of the outer circumference of the cast iron pipes with straps, which increases the complexity.

[0004] In order to solve the above problems, the present application proposes a convenient cast iron pipe lifting device. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes a convenient cast iron pipe lifting device. The utility model is provided with a supporting mechanism to facilitate limiting the two ends of the cast iron pipe, thereby increasing the convenience and stability of lifting.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the utility model provides a convenient cast iron pipe hoisting device, comprising a cast iron pipe, wherein symmetrically arranged support blocks are inserted into the cast iron pipe;

[0009] A supporting mechanism is provided between the two supporting blocks for moving the supporting blocks away from each other.

[0010] Preferably, the propping mechanism comprises a suspension rod and a moving block, one end of the suspension rod is fixedly connected to the moving block, and the moving block is located between two supporting blocks and is slidably connected to the supporting blocks.

[0011] Preferably, a suspension rope is fixedly connected to the suspension rod.

[0012] Preferably, an auxiliary rod is slidably inserted on the suspension rod.

[0013] Preferably, a guide block which is slidably sleeved with the support block is fixedly mounted on the moving block.

[0014] Preferably, a rubber pad is fixedly mounted on the support block.

[0015] The above technical solution of the utility model has the following beneficial technical effects:

[0016] Insert the support block into the end of the cast iron pipe, move the lifting rod, and the lifting rod drives the moving block to move, so as to increase the distance between the two support blocks, so that the support block is pressed against the inner wall of the cast iron pipe to achieve a tightening effect. At this time, only the middle part of the lifting rope needs to be lifted, which increases the convenience and stability of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1-2 As shown, the utility model provides a convenient cast iron pipe hoisting device, comprising a cast iron pipe 1, wherein symmetrically arranged support blocks 2 are inserted into the cast iron pipe 1;

[0022] A supporting mechanism 3 is provided between the two supporting blocks 2 for moving the supporting blocks 2 away from each other.

[0023] In an optional embodiment, the supporting mechanism 3 includes a suspension rod 31 and a moving block 32 , one end of the suspension rod 31 is fixedly connected to the moving block 32 , and the moving block 32 is located between the two supporting blocks 2 and is slidably connected to the supporting blocks 2 .

[0024] Furthermore, a suspension rope 33 is fixedly connected to the suspension rod 31 .

[0025] It should be noted that a hanging ring is fixedly installed in the middle of the lifting rope 33, so that the external hook can be hung on it for lifting and moving.

[0026] In an optional embodiment, an auxiliary rod 34 is slidably inserted into the suspension rod 31 .

[0027] It should be noted that the hanger rod 31 is provided with equally spaced holes adapted to the auxiliary rod 34. The auxiliary rod 34 can be inserted into the corresponding holes so that the auxiliary rod 34 contacts the inner top wall of the cast iron pipe 1, thereby playing an auxiliary supporting role.

[0028] In an optional embodiment, a guide block 321 is fixedly mounted on the moving block 32 and is slidably sleeved with the supporting block 2 .

[0029] It should be noted that both the supporting block 2 and the moving block 32 are provided with inclined surfaces that match each other, and the supporting block 2 is provided with a guide groove that matches the guide block 321 .

[0030] In an optional embodiment, a rubber pad is fixedly mounted on the support block 2 .

[0031] It should be noted that the rubber pad is provided with anti-skid grooves to increase the stability of the support block 2 after it is pressed against the inner wall of the cast iron pipe 1 .

[0032] In the utility model, the support block 2 is inserted into the end of the cast iron pipe 1, and the suspension rod 31 is moved. The suspension rod 31 drives the moving block 32 to move, so as to increase the distance between the two support blocks 2, so that the support block 2 is pressed against the inner wall of the cast iron pipe 1, which plays a clamping role. At this time, only the middle part of the suspension rope 33 needs to be lifted, which increases the convenience and stability of use.

[0033] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
