Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, and in particular to a pipeline spring support and hanger positioning pin removal tool. Background Art

[0002] Spring supports are a type of support commonly used in industrial construction, mainly used to cope with vibration and thermal displacement of pipelines.

[0003] The removal of the positioning pins of the spring hanger is generally carried out during the system water transport stage after the pipeline is installed and the water pressure test is completed. At this time, due to the gravity of the pipeline and the medium, the positioning pins are often squeezed by external force and difficult to remove. The traditional removal method is to cut off the exposed part with a crowbar or a flame, and the remaining part is knocked off. In the above method, the flame can easily damage the anti-corrosion layer and the main structure of the spring hanger, which is not allowed in principle. It is very inconvenient to operate the spring bracket in a high-altitude position with simple tools such as a crowbar. Utility Model Content

[0007] Furthermore, the clamp body is a double-layer steel plate, and the front ends of the double-layer steel plates are bent outward to form installation gaps that are adapted to the thickness of the clamps, and the clamps are fixed in the installation gaps.

[0008] Furthermore, the clamp body and the clamp plate form a semicircular structure as a whole.

[0009] Furthermore, an anti-dropout pin is installed on the shaft end that passes through the first shaft.

[0010] Furthermore, an anti-dropout pin is installed on the shaft end that passes through the second shaft.

[0011] Furthermore, a sleeve is detachably mounted on the end of the pressure rod.

[0012] The utility model provides a spring support hanger locating pin removal tool, a pressure rod and a clamp body use the support as a fulcrum, when the pressure rod is pressed down, the locating pin can be clamped and the upward pulling force can be increased, and the spring support hanger locating pin can be directly and effectively removed. Compared with the traditional method, it saves time and labor, is easy to use, does not need to use fire during the operation process, has good safety and strong practicality.

[0017] In order to make those skilled in the art better understand the present invention, the present invention is further explained in detail below with reference to the accompanying drawings and embodiments. It should be noted that the features in the embodiments and embodiments of the present application can be combined with each other without conflict.

[0018] A typical embodiment of the utility model provides a spring support and hanger positioning pin removal tool, such as Figure 1 As shown, it includes a pressure rod 1, a pliers body 2, a clamp plate 3 and a support 4.

[0019] Among them, the front end of the pressure rod 1 forms an arc-shaped mouth, the front end of the pliers body 2 is fixedly connected to the clamp plate 3, and the front end of the clamp plate 3 forms an arc-shaped mouth; the front middle part of the pressure rod 1 is connected to the middle part of the pliers body 2 through the first axis 5, and the end of the pliers body 2 is connected to the support 4 through the second axis 6.

[0020] The removal tool provided in this embodiment is a pliers-type tool using the lever principle. The tool has a support 4, and the support 4 is hingedly connected to the movable part through an axis. The pressure of the hand-held part can be simultaneously converted into the clamping force of the jaws and the upward pulling force on the clamped part, which can directly and effectively remove the spring support bracket locating pin.

[0021] In a preferred embodiment, Figure 2As shown, the pliers body 2 is made of double-layer steel plates, the front ends of which are bent outward to form installation gaps adapted to the thickness of the clamps 3, and the clamps 3 are fixed in the installation gaps, which helps to improve the overall strength of the active part. The clamps 3 are made of single-layer steel plates, and the clamps 3 and the pliers body 2 are connected as a whole by welding.

[0022] In a relatively specific embodiment, the pliers body 2 and the clamping plate 3 integrally form a semicircular structure.

[0023] In a preferred embodiment, in order to prevent the shaft from slipping during use, an anti-slip pin 7 is installed at the shaft end passing through the first shaft 5 , and an anti-slip pin 7 is installed at the shaft end passing through the second shaft 6 .

[0024] In another preferred embodiment, the end of the pressure rod 1 is detachably covered with a sleeve 8, which can achieve the purpose of extending the length of the pressure rod 1 when necessary and improve the comfort of the hand-held part during use.

[0025] The scope of protection claimed by the present invention is not limited to the above specific implementation methods. For those skilled in the art, the present invention may have various deformations and changes. Any modification, improvement and equivalent substitution made within the concept and principle of the present invention should be included in the protection scope of the present invention.
