Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation pipes, and in particular relates to a self-adaptive clamping device for thermal insulation pipes. Background Art

[0002] Prefabricated direct buried insulated pipe is a pipe buried underground for the purpose of heat preservation and transportation of medium. It can be used in the central heating industry in the north, such as the transportation of hot water and steam at a specific temperature; in some areas of the south, it can be used in the central cooling industry, such as the transportation of hot water and cold water as power; in industry, there are many media in pipelines that need to be transported with heat preservation, for example, in long-distance oil pipelines, oil must be kept at a certain temperature to flow normally due to its very high viscosity. The currently used prefabricated direct buried pipe consists of a steel pipe, a bracket, an insulation layer, and an outer protective pipe. Among them, steel pipes need to undergo rust removal and anti-corrosion processes before assembly, which are generally handled by workers on a workbench. In order to position the steel pipe, a traditional workbench usually uses a wooden positioning block for positioning. This positioning block is wedge-shaped and requires at least two workers to operate. First, one worker holds the steel pipe to keep it still, and the other worker inserts a positioning block on one side of the steel pipe, and then runs to the other side to insert the positioning block. On the one hand, this method is more dangerous for workers. If they are not careful, the steel pipe will roll off the workbench and injure the staff. On the other hand, the operation is time-consuming and laborious. For this reason, the steel pipe clamping structure on the existing workbench needs to be improved. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0017] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figure 1 and Figure 2 As shown, the utility model discloses an adaptive clamping device for a thermal insulation pipe, comprising a workbench 1, the bottom of which is provided with universal wheels.

[0019] The workbench is provided with a clamping mechanism for positioning the steel pipe, and the clamping mechanism includes a base plate 2, a left movable frame 3, a right movable frame 4, a cylinder 5, a guide rail 6 and a clamping wheel 7; two guide rails are fixed on both sides of the bottom of the base plate respectively. Further, in order to improve the stability of the left movable frame and the right movable frame, guide rails and sliders are also arranged between the upper parts of the left movable frame and the right movable frame and the upper part of the base plate. The left movable frame and the right movable frame are respectively located on both sides of the base plate and are respectively connected to the guide rails through sliders. The left movable frame and the right movable frame can move toward each other or oppositely. In order to position the steel pipe, the clamping wheels are respectively arranged on the upper parts of the left movable frame and the right movable frame. A connecting rod 8 is connected to the bottom of the left movable frame and the right movable frame respectively, and each connecting rod is hinged to the two ends of a rotating plate 9 respectively. The middle part of the rotating plate is hinged to the bottom of the base plate. The cylinder is fixed to the bottom of the base plate, and the piston rod of the cylinder is connected to one end of the left movable frame or the right movable frame. When the cylinder is activated, assuming that it drives the left moving frame to move, then due to the action of the connecting rod and the rotating plate, the other right moving frame will also move. Assuming that the left moving frame moves to the right, then the right moving frame will move to the left, which is exactly opposite to the moving direction of the left moving frame.

[0020] In order to adapt to the surface of the steel pipe and closely contact the surface of the steel pipe, the clamping wheel is installed on the V-shaped bracket 10, and the middle part of the V-shaped bracket is hinged with the left movable frame or the right movable frame through a pin. Each V-shaped bracket has a clamping wheel at both ends, which will swing and adjust automatically when close to the side of the steel pipe. Further, at least two groups of V-shaped brackets are provided on the left movable frame and the right movable frame, respectively fixing the upper ends of the two.

[0021] Further, in order to facilitate the assembly of the clamping mechanism, the bottom of the base plate is fixed to the workbench through a support frame.

[0022] During use, when the steel pipe needs to be surface treated, the left moving frame and the right moving frame are first in an open state, that is, the piston rod of the cylinder is extended, and the distance between the left moving frame and the right moving frame is the farthest. After the steel pipe is placed on the bottom plate, the piston rod of the cylinder is retracted, and the left moving frame and the right moving frame drive the clamping wheels to move toward the steel pipe, so that the clamping wheels are close to both sides of the steel pipe, so that the steel pipe cannot rotate and cannot roll off the workbench, thereby improving the safety of the workers.

[0023] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
