Description

Technical Field

[0001] This utility model relates to the field of construction technology of inverted installation of cold water tanks, and in particular to an adjustable diagonal brace for lifting columns in the inverted installation of cold water tanks. Background Technology

[0002] With the widespread application of large cold water storage tanks in HVAC systems, the inverted installation method for cold water storage tanks has become the mainstream technology in the industry.

[0003] In traditional inverted installation construction, the diagonal bracing structure of the lifting column is generally supported by welding steel pipes between the bottom plate of the cold water tank and the lifting column. This diagonal bracing structure has significant drawbacks: First, the welding operation requires multiple hot cutting and welding operations on the lifting column, which can easily damage the main structure of the lifting column and affect its load-bearing capacity; second, the tilt angle of the welded steel pipe cannot be adjusted according to the construction height, causing the supporting force to deviate from the optimal force transmission path under some working conditions, posing a safety hazard; third, the welded steel pipes need to be cut and dismantled after the completion of each stage of construction, resulting in a large amount of material waste and low turnover rate.

[0004] The existing adjustable-length supports are mainly used as vertical structural supports, and there is a risk of bending and deformation when they are used as diagonal bracing structures.

[0005] Therefore, there is an urgent need to develop a diagonal bracing device with adjustable support length, detachable structure, and resistance to bending to overcome the bottlenecks of traditional construction. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned problems in the existing technology and provide an adjustable diagonal brace for lifting columns using the inverted method of cold water tank.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] An adjustable diagonal brace for lifting columns using a cold water storage tank inversion method includes:

[0009] A base, which is mounted on the bottom plate of the cold water storage tank;

[0010] The lower circular tube is hinged to the base at its bottom, and N reinforcing ribs arranged in a circular array with the lower circular tube as the center are welded to the outer wall of the lower circular tube.

[0011] A clamp, which is installed on the lifting column;

[0012] The upper circular tube has its top hinged to one side of the clamp. A threaded rod coaxial with the upper circular tube is welded to the bottom of the upper circular tube. A rotating seat is screwed onto the threaded rod. The bottom of the rotating seat and the lower part of the threaded rod are inserted into the lower circular tube. More than N reinforcing ribs are welded to the outer wall of the upper circular tube in a circular array centered on the circular tube.

[0013] The support cage is slidably fitted with the upper reinforcing rib, allowing the support cage to move axially along the upper circular tube. The bottom of the support cage is fitted onto the rotating seat.

[0014] The rotating seat includes an annular rotating body, the inner side of which is provided with an internal threaded hole that engages with the external threaded rod; the outer middle part of the rotating body is provided with an annular thickened support part, the bottom of the rotating body is inserted into the lower round tube, and the bottom end of the thickened support part abuts against the top end of the lower round tube.

[0015] The thickened support has two handles welded to its side, which are symmetrically arranged about the central axis of the rotating body.

[0016] The support cage includes N support rods arranged in a circular array, a circular support ring, and multiple circular connecting rings. The bottom ends of the support rods are welded to the top ends of the support ring, and the inner sides of the connecting rings are welded to the outer sides of the N support rods. Each support rod has a groove extending along its long axis on its centripetal side, and each groove slides in conjunction with an upper reinforcing rib. The top outer side of the rotating body has a guide groove with a semi-circular cross-section. Multiple hexagonal set screws are screwed onto the ring wall of the support ring. The heads of the hexagonal set screws are hemispherical and slide in conjunction with the guide grooves.

[0017] The centripetal side of the support rod is a curved surface that fits tightly against the outer wall of the upper circular tube.

[0018] The width of the support rod is equal to the opening width of the groove.

[0019] The beneficial effects of this utility model are as follows: The lower round tube, upper round tube, external threaded rod, and rotating seat work together to adjust the length of the external threaded rod inserted into the lower round tube by rotating the rotating seat, thereby adjusting the support length of the adjustable diagonal brace; the clamp hinged to the top of the upper round tube is installed on the lifting column, eliminating the need for welding between the top of the upper round tube and the side of the lifting column, facilitating adjustment of the clamp's support position on the lifting column; furthermore, the bottom of the lower round tube is hinged to the base, allowing for adjustment of the adjustable diagonal brace's support angle by changing the length of the adjustable support and the installation height of the clamp without changing the base's installation position; lower reinforcing ribs are provided on the outer wall of the lower round tube to improve its bending resistance, upper reinforcing ribs are provided on the outer wall of the upper round tube to improve its bending resistance, and a support cage fitted at the bottom of the rotating seat improves the external threaded rod's bending resistance; the combination of lower reinforcing ribs, upper reinforcing ribs, and the support cage enhances the adjustable diagonal brace's bending resistance.

Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 9 As shown, an adjustable diagonal brace for lifting columns using an inverted method for storing cold water tanks includes a base 1, a lower round tube 2, a clamp 3, an upper round tube 4, an externally threaded rod 5, a rotating seat 6, and a support cage 7.

[0033] The base 1 is installed on the bottom plate of the cold water storage tank. The base 1 includes a rectangular mounting plate 11 and two lower hinge blocks 12 vertically welded to the middle of the top of the mounting plate 11, and the two lower hinge blocks 12 are parallel to each other. The mounting plate 11 has four through holes 14 arranged in a rectangular array. A second through hole is opened on the bottom plate of the cold water storage tank. An installation groove communicating with the second through hole is drilled on the foundation of the cold water storage tank below the second through hole. The chemical bolt's chemical tube is inserted into the installation groove after passing through the second through hole. The screw of the chemical bolt is screwed into the installation groove with an electric drill until the chemical tube of the chemical bolt breaks and the chemical flows out. After the flowed chemical solidifies, the top of the chemical bolt is inserted into the first through hole 14. Then, the nut of the chemical bolt is screwed onto the screw of the chemical bolt, so that the nut of the chemical bolt presses against the mounting plate. The mounting plate is then installed on the bottom plate of the cold water storage tank.

[0034] The bottom of the lower round tube 2 is hinged to the base 1. Specifically, a lower cylindrical block 22 is welded to the bottom end of the lower round tube 2, and a lower hinge block 23 is vertically welded to the bottom end of the lower cylindrical block 22. The lower hinge block 23 has a left-right through lower hinge hole 24, and the lower hinge block 12 has a left-right through lower hinge hole 13. A lower pin 8 is inserted into the lower hinge hole 12 and the lower hinge hole 23. A cotter pin 81 is installed on the lower pin 8 to prevent the lower pin 8 from disengaging from the lower hinge hole 13 and the lower hinge hole 24. The lower hinge block 12 and the lower hinge block 23 can rotate with the lower pin 8 as the center to adjust the included angle between the lower round tube 2 and the base 1.

[0035] Four reinforcing ribs 21 are welded to the outer wall of the lower circular tube 2, arranged in a circular array with the lower circular tube as the center. A reinforcing ring 25 is welded between the top of the four reinforcing ribs 21 and the lower circular tube 2, and the top of the reinforcing ring 25 is flush with the top of the lower circular tube 2.

[0036] The clamp 3 is installed on the lifting column. Specifically, the clamp 3 includes two fan-shaped clamp plates 31. Each clamp plate 31 has an outwardly extending wing plate 32 at each end. Each wing plate 32 has at least two mounting holes 33. The wing plates 32 on the same side of the clamp 3 are locked together with hexagonal bolts 34 and hexagonal nuts 35, so that the two clamp plates 31 clamp the lifting column. The screw of the hexagonal bolt 34 passes through the mounting hole 33.

[0037] The top of the upper round tube 4 is hinged to one side of the clamp 3. Specifically, an upper cylindrical block 42 is welded to the top of the upper round tube 4, and an upper hinge block 43 is vertically welded to the top of the upper cylindrical block 42. The upper hinge block 43 has a through upper hinge hole 44. Two parallel upper hinge blocks 36 are welded to the middle of the outer side of a clamp plate 31. The upper hinge block 36 has a through upper hinge hole 37. An upper pin 9 is inserted into the upper hinge hole 37 and the upper hinge hole 44. A cotter pin 91 is installed on the upper pin 9 to prevent the upper pin 9 from disengaging from the upper hinge hole 37 and the upper hinge hole 44. The upper hinge blocks 36 and the upper hinge block 43 can rotate around the upper pin 9 to adjust the angle between the upper round tube 4 and the clamp 3.

[0038] A threaded rod 5, coaxial with the upper circular tube 4, is welded to the bottom of the upper circular tube 4. A rotating seat 6 is screwed onto the threaded rod 5. The bottom of the rotating seat 6 and the lower part of the threaded rod 5 are inserted into the lower circular tube 2. Specifically, the rotating seat 6 includes an annular rotating body 61. The inner side of the rotating body 61 is provided with an internal threaded hole 62 that engages with the threaded rod 5. An annular thickened support part 63 is provided in the middle of the outer side of the rotating body 61. The bottom of the rotating body 61 is inserted into the lower circular tube 2, and the outer diameter of the rotating body 61 is equal to the inner diameter of the lower circular tube 2. The bottom end of the thickened support part 63 abuts against the top end of the lower circular tube 2.

[0039] Two handles 64 are welded to the side of the thickened support part 63, which are symmetrically arranged about the central axis of the rotating body 61. The handles 64 make it convenient for construction personnel to rotate the rotating seat 6 by holding the handles 64, adjust the position of the rotating seat 6 on the external threaded rod 5, and then adjust the length of the lower part of the external threaded rod 5 inserted into the lower round tube 2.

[0040] Four or more upper reinforcing ribs 41, arranged in a circular array around the outer wall of the upper circular tube 4, are welded on it. The support cage 7 slides with the upper reinforcing ribs 41, allowing the support cage 7 to move along the axial direction of the upper circular tube 4.

[0041] The support cage 7 includes four support rods 71 ​​arranged in a circular array, a circular support ring 72, and multiple circular connecting rings 73. The bottom end of the support rod 71 is welded to the top end of the support ring 72, and the inner side of the connecting ring 73 is welded to the outer side of the four support rods 71 ​​respectively. The centripetal side of the support rod 71 is provided with a sliding groove 74 extending along the long axis of the support rod 71. Each sliding groove 74 is slidably engaged with an upper reinforcing rib 41, and the width of the support rod 71 is equal to the opening width of the sliding groove 74.

[0042] The bottom of the support cage 7 is fitted onto the rotating seat 6. Specifically, a guide groove 65 with a semi-circular cross-section is provided on the outer side of the top of the rotating body 61. Multiple hexagonal set screws 75 are screwed onto the ring wall of the support ring 72. The head of the hexagonal set screw 75 is hemispherical and slides with the guide groove 65. The inner diameter of the support ring 72 is equal to the outer diameter of the rotating body 61.

[0043] The radial side of the support rod 71 is a curved surface that fits tightly against the outer wall of the upper circular tube 4, so as to increase the contact area between the support rod 71 and the outer wall of the upper circular tube 4, so that the support rod 71 is subjected to force and shares the radial pressure acting on the external thread rod 5.

[0044] The adjustable diagonal brace's support length can be adjusted by using a lower round tube, an upper round tube, an external threaded rod, and a rotating seat to adjust the length of the external threaded rod inserted into the lower round tube.

[0045] The clamp, which is hinged to the top of the upper round tube, is installed on the lifting column, so that there is no need to weld the top of the upper round tube to the side of the lifting column, which makes it easy to adjust the support position of the clamp on the lifting column.

[0046] Furthermore, the bottom of the lower round tube is hinged to the base, so the support angle of the adjustable brace can be adjusted by changing the length of the adjustable support and the installation height of the clamp without changing the installation position of the base.

[0047] Lower reinforcing ribs are installed on the outer side wall of the lower circular tube to improve its bending resistance, and upper reinforcing ribs are installed on the outer side wall of the upper circular tube to improve its bending resistance. A support cage fitted at the bottom of the rotating seat is installed to improve the bending resistance of the external threaded rod. The installation of lower reinforcing ribs, upper reinforcing ribs, and support cage improves the bending resistance of the adjustable diagonal brace.

[0048] Because of the assembled connection between the clamp and the lifting column, and the assembled connection between the base and the bottom plate of the cold water tank, compared with the traditional welding connection and subsequent cutting and disassembly, the wear and tear caused by welding and cutting of the adjustable brace is reduced. In addition, each component can be disassembled, replaced and repaired, improving the reusability of the adjustable brace.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
