Description
Technical Field
[0001] The utility model relates to the field of municipal engineering, in particular to a reinforced concrete pipe hanger for a municipal rainwater pipeline. Background Art
[0002] The government drainage pipeline is composed of multiple sections of large-diameter reinforced concrete pipes buried deep underground. During the construction process, a crane is used to lift the concrete pipes to the installation location section by section. The most important thing for lifting concrete pipes with a crane is a concrete pipe lifter.
[0003] At present, a Chinese utility model with a publication number of CN214456149U discloses a municipal rainwater pipeline reinforced concrete pipe hanger, including a hanger steel plate, a first hanger steel plate is arranged at the bottom of the hanger steel plate, the hanger steel plate and the first hanger steel plate are an integrated structure, a pipe clamping groove is formed at the position between the first hanger steel plate and the hanger steel plate, a first hanging hole is arranged at the position near the upper left corner of the hanger steel plate surface, a second hanging hole is arranged at the position near the upper right corner of the hanger steel plate surface, and a plurality of wire clamping devices are arranged at the rear end surface of the hanger steel plate; the device is simple and convenient to operate when hanging concrete pipes, and can reduce damage to the concrete pipe mouth, which is convenient for recycling between different construction sites. The device greatly reduces the utilization rate of labor and increases work efficiency. The device has low cost, high efficiency, reduces cost, can be recycled, and has a simple manufacturing process (only one person is needed to operate the pipe hanger).
[0004] The existing concrete pipe hoists do not have the function of preventing the concrete pipe from breaking. Generally, the hoists are used to hoist the two ends of the concrete pipe. If the concrete pipe is long, the middle part of the concrete pipe will be subjected to greater force under the action of gravity during hoisting, and it is easy to break, causing losses and posing safety hazards. Concrete pipes of different lengths cannot be hoisted. Generally, hoists can only hoist concrete pipes of fixed lengths. If you want to hoist concrete pipes of different lengths, you need to replace the corresponding hoists, which is very troublesome and increases the cost of use. The applicability is low. In order to solve the above-mentioned problems, we propose a municipal rainwater pipeline reinforced concrete pipe hoist. Utility Model Content
