Description

Technical Field

[0001] The utility model relates to the technical field of steel cylinder concrete pipe hoisting, in particular to a prestressed steel cylinder concrete pipe hanging device. Background Art

[0002] Prestressed steel cylinder concrete pipe refers to a water pipe made by winding circumferential prestressed steel wire on a high-strength concrete pipe core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. It is a composite pipe composed of thin steel plate, high-strength steel wire and concrete. It fully and comprehensively exerts the tensile strength and easy sealing of steel and the compressive and corrosion resistance of concrete, and has the characteristics of high sealing, high strength and high impermeability.

[0003] At present, prestressed steel tube concrete pipes on the market are all hoisted with C-type hoists. However, when hoisting, the contact between the support part and the pipe body of the traditional C-type hoist is a rectangular strip, which causes the contact surface between the inner wall of the pipe body and the support part to be stressed at the corners of the support part. As the contact range is small and the weight of the pipe body itself is extremely large, the inner side of the pipe body is easily damaged during the hoisting process, so how to solve this problem needs to be considered. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a prestressed steel cylinder concrete pipe hanging device, which can increase the contact surface between the supporting part and the inner wall of the steel cylinder concrete pipe during the hanging process, thereby effectively improving the contact stability and avoiding damage to the pipe body during contact.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hanging device for a prestressed steel cylinder concrete pipe comprises a C-shaped support member, wherein the C-shaped support member is composed of two horizontal bars and one vertical bar, and the upper end of the horizontal bar located above is fixedly connected to a hanging ear; a supporting mechanism, wherein the supporting mechanism comprises a T-shaped slide groove opened on the right side of the lower horizontal bar, and a T-shaped slider that can slide left and right is arranged in the T-shaped slide groove, and the upper end of the T-shaped slider is fixedly connected to the support bar; and a replacement mechanism, wherein the replacement mechanism is used to replace the support bar.

[0007] Preferably, a stabilizing block is fixedly connected to the right side of the upper horizontal bar.

[0008] Preferably, the upper end surface of the support bar is an arc-shaped surface.

[0009] Preferably, a rubber pad is provided at the upper end of the support bar.

[0010] Preferably, the replacement mechanism includes an insertion rod vertically penetrating the bottom of the T-shaped slide groove, the lower end of the insertion rod extends to the outside and is fixedly connected to a pulling block, and the upper end of the pulling block is elastically connected to the lower end of the lower horizontal bar through a spring.

[0011] Preferably, a limiting groove is provided at the lower end of the T-shaped slider, the upper end of the insertion rod extends into the limiting groove and is slidably connected to the inner wall of the limiting groove, the insertion rod is a rectangular rod, and the limiting groove is a rectangular groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] A rubber pad is provided, and the use of the rubber pad can provide soft support for the inside of the tube body, so that the contact damage caused to the tube body is smaller. The upper end surface of the support strip is in an arc shape, so that the interaction surface between the tube body and the support strip is larger. When the overall force remains unchanged, the local pressure is smaller, so that the damage to the inner wall of the tube body is smaller, and the actual use effect is better. Through the spring, plug rod and pulling block structure, the support strip can be replaced more conveniently to adapt to tubes of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
