Clamp used during pipeline hot melting

Abstract

The invention provides a clamp used during pipeline hot melting, and belongs to the field of clamps. The clamp aims to solve the problems that an existing clamp used during pipeline hot melting is fixed in clamping size, cannot clamp multiple types of pipelines, and inconvenient to use. The clamp comprises a support, a distance adjusting device and two clamping devices, wherein the distance adjusting device is slidably arranged on the support, one of the clamping devices is arranged on the support, and the other one of the clamping devices is arranged on the distance adjusting device. The clamp adopts a chain for clamping fixing, can be suitable for clamping the pipelines of various sizes and types, is convenient to operate, high in universality and convenient to maintain on site, saves oncost and time, and is small in size, light in weight, low in manufacturing cost, available in pipeline maintenance, simple in structure, convenient to operate, time-saving and labor-saving, and highin pipeline hot melting welding efficiency.

Description

technical field [0001] The invention relates to the field of clamps, in particular to a pipe hot-melt clamp. Background technique [0002] At present, in the process of laying pipelines such as natural gas pipelines and water pipe networks, it is often necessary to weld and connect pipelines. Hot melt welding is currently one of the most important methods for pipeline welding. When performing pipe welding operations, it is necessary to fix the two pipes on the same axis first, and generally use pipe clamps to complete this operation. The clamping model size of the commonly used pipeline clamps is fixed, and a set of clamps can only clamp and fix one type of pipeline, which has poor adaptability and flexibility and poor versatility. At present, purely manual methods are often used for hot melting. In pipe welding operations, the efficiency of artificial hot-melt welding of pipes is very low, and the quality of hot-melt welding is poor; the hot-melt pipe welding fixtures comm...

Problems solved by technology

The clamping model size of the commonly used pipeline clamps is fixed, and a set of clamps can only clamp and fix one type of pipeline, which has poor adaptability and flexibility and poor versatility. At present, purely manual methods are often used for hot melting. In pipe welding operations, the efficiency of artificial hot-melt welding of pipes is very low, and the quality of hot-melt welding is poor; the hot-melt pipe welding fixtures commonly used in the market are large in size, heavy in weight, and high in cost. Few people use the disadvantages of heat-melt welding pipes such as low efficiency
