Description

Technical Field

[0001] The utility model relates to the field of hanger springs, in particular to a hanger spring. Background Art

[0002] With the rapid development of society and the continuous expansion of urban infrastructure, sewer pipes, water pipes, natural gas pipes, oil pipes and industrial production equipment pipelines are also increasing. Pipelines are divided into buried laying and overhead laying. The advantage of buried laying is that underground space can be utilized to reduce the occupation of space above the ground, but the disadvantage is that the pipeline is highly corrosive and difficult to inspect and repair. Overhead laying is mainly for industrial production equipment pipelines, which is convenient for construction, operation, inspection and maintenance. Overhead laying requires the use of hanger spring brackets to support the pipelines.

[0003] Before installing the hanger spring, check the load position of the spring indicating operation and the load position indicating cold installation, then install the required pipe on the top seat, and finally pull out the positioning pin to complete the installation.

[0004] During subsequent use, the weight transmitted in the pipe above the top seat compresses the spring, which may cause the spring to be loaded. Eventually, the spring exceeds the load position and cannot play a good supporting role. Therefore, it is necessary to check the status of the hanger spring frequently to prevent collapse or damage to the pipe. The existing technology is to judge by looking at the identification symbol next to the square groove. The small identification is not obvious, which may lead to misjudgment. Moreover, after a long time, the identification will not be clear, which will affect the judgment and cause accidents due to untimely replacement. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a hanger spring to solve the technical problem that the spring load mark is not obvious.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hanger spring, comprising an installation box and a base, the base being installed at the bottom of the installation box, the top cover being installed at the top of the installation box, a square groove being opened on one side of the installation box, a spring being installed inside the installation box, a support ring being fixed inside the installation box, and a movable block being installed inside the support ring, the bottom of the movable block being connected to a fixed block, and one end of the fixed block being movably connected to an inclined block, an installation groove being opened inside the installation box, and a buffer rod being movably connected in the installation groove.

[0007] By adopting the above technical solution, the problem of unclear spring load mark is solved. When the spring reaches the load limit position, the protrusion under the pressing block will squeeze the movable block, causing the fixed block to protrude outward. The color of the side of the fixed block is brighter because the side is inside the support ring and will not be damaged by wind and rain and will not be easily blurred. When the protrusion protrudes outward, the color of the side can be seen, which can serve as a good reminder, making it convenient for inspectors to check and replace it in time to avoid accidents.

[0008] The utility model is further configured such that a plurality of grooves are provided around the base, and bolts are installed inside the grooves.

[0009] By adopting the above technical solution, the base can be fixed to the ground with convenient bolts to ensure that the installation box is not easily moved.

[0010] The present invention is further configured such that a support column is installed through the middle of the top cover, a top seat is installed on the top of the support column, a pressing block is installed on the bottom of the support column, and a protrusion is fixed on the bottom of the pressing block.

[0011] By adopting the above technical solution, the top seat can be connected to the transport pipeline, and the bottom of the pressing block is connected to the spring, which plays a good shock-absorbing role for the transport pipeline. The lower protrusion of the pressing block can contact the movable block in advance when the spring is about to be compressed to the limit position, and slowly push the inclined block out of the installation box, making it convenient for the staff to understand the condition of the spring.

[0012] The present invention is further configured such that the end of the fixed block is in an arc shape, and the inclined block is movably connected to the supporting ring.

[0013] By adopting the above technical solution, the arc shape at the end of the fixed block reduces the friction between the two when the fixed block pushes the inclined block, making the push more convenient. The inclined block and the support ring are connected together, but the inclined block will not separate from the support ring, which is convenient for staff to check the equipment.

[0014] The utility model is further configured such that the length of the buffer rod is greater than the distance from the outer wall of the support column to the inner wall of the installation box.

[0015] By adopting the above technical solution, when the pressing block moves downward, one end of the buffer rod can be supported on the outer wall of the support column, which can bear part of the pressure for the spring and increase the service life of the spring.

[0016] The utility model is further configured such that a rubber block is provided on the top end of the buffer rod.

[0017] By adopting the above technical solution, the rubber block can act as a buffer and reduce the wear of the buffer rod on the support column. Because rubber is a flexible material, when the critical value of the spring is reached, the buffer rod can continue to move downward to avoid the buffer rod being subjected to excessive pressure and causing damage.

[0018] The present invention is further configured such that the outer wall of the buffer rod is completely fitted with the inner wall of the mounting groove.

[0019] By adopting the above technical solution, the buffer rod will not protrude from the installation groove and will not affect the normal falling of the pressing block.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The utility model solves the problem of unclear spring load mark by providing a support column, a top seat, a pressing block, a convex block, a spring, a support ring, a movable block, an inclined block and a fixed block. When the spring reaches the load limit position, the convex block under the pressing block will squeeze the movable block, causing the fixed block to bulge outward. The color of the side of the fixed block is brighter because the side is inside the support ring and will not be damaged by wind and rain and will not be easily blurred. When the convex block bulges outward, the color of the side can be seen, which can serve as a good reminder, making it convenient for inspectors to check and replace it in time to avoid accidents.

[0022] 2. The utility model solves the problem that when the spring is about to reach the load limit position, the buffer rod can play a buffering and supporting role on the support rod, slowing down the falling speed of the pressing block, thereby increasing the service life of the hanger spring and preventing accidents caused by untimely inspection, which may result in the spring being discovered after it has reached the load limit position and there is no time to prepare for material replacement.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] A hanger spring, such as Figure 1 - Figure 6 As shown, it includes an installation box 1 and a base 2, and the base 2 is installed at the bottom of the installation box 1.

[0033] Specifically, a top cover 101 is installed on the top of the installation box 1, and a square groove 102 is opened on one side of the installation box 1. A spring 4 is installed inside the installation box 1. The square groove 102 makes it convenient for staff to view the internal structure of the installation box 1. A support ring 5 is fixed inside the installation box 1, and a movable block 6 is installed inside the support ring 5. The bottom of the movable block 6 is connected to a fixed block 62, and one end of the fixed block 62 is movably connected to an inclined block 61. The protrusion 33 contacts the movable block 6 and continues to move downward. Then the fixed block 62 at the bottom of the movable block 6 pushes the inclined block 61 to move outward, indicating that the spring 4 is about to reach the load limit position and the spring 4 needs to be replaced as soon as possible. An installation groove 103 is opened inside the installation box 1, and a buffer rod 7 is movably connected in the installation groove 103. When the pressing block 32 moves downward, until the pressing block 32 is separated from the buffer rod 7, the buffer rod 7 tilts outward, and finally one end of the buffer rod 7 will rest on the outer wall of the support column 3, so that the pressing block 32 slows down the downward movement.

[0034] See also Figure 1 The base 2 is provided with multiple groups of grooves 21 around it, and bolts 22 are installed inside the grooves 21 to facilitate the bolts 22 to fix the base 2 on the ground, thereby ensuring that the installation box 1 is not easily moved.

[0035] See also Figure 1 and Figure 2A support column 3 is installed through the middle of the top cover 101, and a top seat 31 is installed on the top of the support column 3, a pressing block 32 is installed at the bottom of the support column 3, and a protrusion 33 is fixed at the bottom of the pressing block 32. The top seat 31 can be connected to the transportation pipeline, and the bottom of the pressing block 32 is connected to the spring 4, which plays a good shock-absorbing role for the transportation pipeline. The protrusion 33 is lower than the pressing block 32. When the spring 4 is about to be compressed to the limit position, the protrusion 33 can contact the movable block 6 in advance, and slowly push the inclined block 61 out of the installation box 1, which is convenient for the staff to understand the condition of the spring 4.

[0036] See also Figure 6 The end of the fixed block 62 is arc-shaped, and the inclined block 61 is movably connected to the support ring 5. The arc-shaped end of the fixed block 62 reduces the friction between the two when the fixed block 62 pushes the inclined block 61, making it more convenient to push. The inclined block 61 and the support ring 5 are connected together, but the inclined block 61 will not separate from the support ring 5, which is convenient for staff to check the equipment.

[0037] See also Figure 2 - Figure 4 The length of the buffer rod 7 is greater than the distance from the outer wall of the support column 3 to the inner wall of the installation box 1. When the pressing block 32 moves downward, one end of the buffer rod 7 can be supported on the outer wall of the support column 3, which can bear part of the pressure for the spring 4 and increase the service life of the spring 4.

[0038] See also Figure 5 A rubber block 71 is provided at the top of the buffer rod 7. The rubber block 71 can act as a buffer to reduce the wear of the buffer rod 7 on the support column 3. Because rubber is a flexible material, when the critical value of the spring 4 is reached, the buffer rod 7 can continue to move downward to avoid the buffer rod 7 from being subjected to excessive pressure and causing damage.

[0039] See also Figure 2 The outer wall of the buffer rod 7 is completely in contact with the inner wall of the mounting groove 103 , and the buffer rod 7 does not protrude from the mounting groove 103 , and does not affect the normal falling of the pressing block 32 .

[0040] The working principle of the present invention is as follows: when installing the hanger spring 4, first fix the base 2 on the ground with the bolt 22 passing through the groove 21, and then install the pipeline equipment on the top seat 31. The top seat 31 will push the support column 3 downward to move downward. The original pressing block 32 is at the top inside the installation box 1. At this time, the buffer rod 7 is compressed in the installation groove 103. When the pressing block 32 moves downward, until the pressing block 32 is separated from the buffer rod 7, the buffer rod 7 tilts outward. Since the length of the buffer rod 7 is slightly longer than the distance from the outer wall of the support column 3 to the inner wall of the installation box 1, one end of the buffer rod 7 will finally rest against the outer wall of the support column 3, slowing down its downward movement. Since the end of the buffer rod 7 in contact with the support column 3 is the rubber block 71, when the pressing block 32 continues to move downward, the support column 3 squeezes the rubber block 71 so that the pressing block 32 only slows down the movement speed, but does not stop moving.

[0041] At this time, the protrusion 33 at the bottom of the pressing block 32 contacts the movable block 6 and continues to move downward. Then the fixed block 62 at the bottom of the movable block 6 pushes the inclined block 61 to move outward, indicating that the spring 4 is about to reach the load limit position and the spring 4 needs to be replaced as soon as possible.

[0042] When the pressing block 32 reaches the load limit position, the pressing block 32 contacts the support ring 5, and most of the inclined block 61 is pushed out of the outer wall of the installation box 1, indicating that the spring 4 has reached the limit position and the spring 4 needs to be replaced immediately.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
