Problems solved by technology

[0003] At present, heat-shrinkable sleeves are generally heated by manual hand heaters, especially the heating of heat-shrinkable sleeves needs to be repeated repeatedly, which is time-consuming and labor-intensive.
Especially when heating large-diameter pipes, two people usually need to stand opposite to each other, and hold the heater to heat the heat-shrinkable sleeve, which has certain potential safety hazards.

Embodiment 1

[0031] see Figure 1-Figure 6 , a pipe filling device, characterized in that it includes a movable frame 1, the frame 1 includes a bottom plate 101 and a top plate 102, an upper vertical plate 104 is arranged below the top plate 102, and the bottom plate 101 corresponds to the upper vertical plate 104 The lower vertical plate 103 is arranged at the position, and the upper vertical plate 104 and the lower vertical plate 103 are connected by a semicircular fixed annular plate 2;

[0032] It also includes a semicircular movable annular plate 3 that can be spliced ​​with the fixed annular plate 2 into a circle. The outer walls of the fixed annular plate 2 and the movable annular plate 3 are concentrically provided with a semicircular annular boss 13. On the annular boss 13 An annular slideway 10 is provided through the axial direction of the fixed annular plate 2, and a slide plate 7 is slidably arranged in the annular slideway 10. Limiting baffles are arranged at both ends of the...

Embodiment 2

[0045] see Figure 1-Figure 9 , the only difference from Embodiment 1 is that it is the same as the drive mechanism 6 and other technical features. A rectangular opening 1022 is provided on the limiting opening 1021 on the same side as the fixed annular plate 2. The opening end of the rectangular opening 1022 is far away from the heater 5. On the side, the driving mechanism 6 includes a rack 605 arranged in the rectangular opening 1022, the rack 605 is fixed on the vertical bar 9, and the lower end of the top plate 102 is rotated with a gear 603, the gear 603 is driven by a motor 604 capable of forward and reverse rotation, and the motor 604 is fixed below.

Abstract

The invention provides a pipeline joint coating device, and belongs to the technical field of pipeline construction. According to the technical scheme, a movable machine frame comprises a bottom plate and a top plate, an upper vertical plate is arranged below the top plate, a lower vertical plate is arranged on the bottom plate, and the upper vertical plate and the lower vertical plate are connected through a fixed annular plate; semicircular annular bosses are concentrically arranged on the outer wall of the fixed annular plate and the outer wall of a movable annular plate, an annular sliding way is formed in the annular bosses in the axis direction of the fixed annular plate in a penetrating mode, a sliding plate is arranged in the annular sliding way, and limiting baffles are arranged at the two ends of the sliding plate and located on the outer sides of the annular bosses; a connecting rod is rotationally arranged on each fixing shaft, a vertical rod is hinged to the other end of each connecting rod, and a limiting opening is formed in the top plate; a fixing structure of a heater is arranged on each limiting baffle; and a power mechanism driving the vertical rods to move in the vertical direction is further included. The pipeline joint coating device has the beneficial effect of being capable of assisting manual heating of a thermal shrinkable sleeve.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a pipeline repairing device. Background technique [0002] As we all know, pipelines are widely used in many industries such as petroleum, chemical industry, electric power, communication, municipal and construction, and the use environment is also relatively complicated. In order to ensure the service life of pipelines, pipelines need to be treated with anticorrosion, and PE materials are usually used for anticorrosion treatment. Especially at the joints of the pipe joints, anti-corrosion is very important. Now, the commonly used anti-corrosion method is to use heat-shrinkable sleeve joint technology, which is to heat the heat-shrinkable sleeve and put it on the joint of the pipeline. After the heat-shrinkable sleeve naturally cools and shrinks, it is fixed on the joint to achieve anti-corrosion purposes. [0003] At present, the heating of the heat-shrinkable sle...
