[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine.

[0003] After the traditional fan installation base is hoisted into the base, a series of fixing work is required, including bolt tightening, adjusting the level, etc. These steps are usually time-consuming and require professional installers to operate, which undoubtedly increases the installation cost and time cost. Once the fan is installed, the adjustment function of the base is usually limited, and it is difficult to meet the angle adjustment requirements caused by environmental factors during the operation of the fan. For this reason, we propose an adjustable large fan installation base. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable large-scale fan installation base, comprising a base, an arc-shaped limit groove is opened on the surface of the base, a limit clamping plate is slidably installed inside the arc-shaped limit groove, and adjustment components for driving the limit clamping plate to move are arranged on both sides of the base, an annular support plate is installed on the top surface of the limit clamping plate, a mounting cylinder is installed through the inner side of the annular support plate, and a fan is installed inside the mounting cylinder;

[0006] A positioning groove is provided on the top of the annular support plate, and a block passing through the positioning groove is installed on the top of the mounting tube. Mounting grooves are provided on both sides of the block. Two movable columns are installed on the top of the block for sliding through. An elastic component connected to the inner wall of the mounting groove is provided at the lower end of the movable column. Multiple blocks are installed on one side of the movable column, and a lifting connector is provided on the top of the movable column.

[0007] Preferably, the adjustment assembly includes two hydraulic push rods, which are respectively fixedly mounted on both sides of the base, and the output ends of the hydraulic push rods pass through the base to the arc-shaped limit groove. A resistance block is fixedly mounted on the output ends of the hydraulic push rods, and the resistance block resists both sides of the limit clamping plate.

[0008] Preferably, the elastic component comprises a lifting plate, the lifting plate is welded to the bottom end of the movable column, a spring is fixedly mounted on the bottom of the lifting plate, and one end of the spring away from the lifting plate is fixedly mounted on one side of the mounting groove.

[0009] Preferably, the spacing between the stoppers installed on the surfaces of the movable columns on both sides matches the width dimension of the annular support plate.

[0010] Preferably, the lifting connector is specifically two lifting ears, and the two lifting ears are respectively installed on the top of two movable columns.

[0011] Preferably, the width dimension of the block matches the width dimension of the positioning groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The adjustable large fan mounting base changes the positions of the two abutment blocks by controlling the movement of the output end of the hydraulic push rod, so that the abutment block keeps the limit card plate between the two abutment blocks while moving, so that the limit card plate can slide inside the arc limit groove. Since the arc limit groove is arc-shaped, the limit card plate can change the angle when driving the annular support plate to move, thereby driving the fan to change the angle through the mounting tube, thereby improving the flexibility of the fan and the base.

[0014] 2. The adjustable large-scale fan installation base, the lifting equipment pulls the movable column upward through the lifting ear, so that the lifting plate contacts the top of the inner side of the installation groove, thereby pulling the block and the installation tube to be lifted. After the installation tube is lifted into the annular support plate, the block is just inserted into the positioning groove. After the installation tube and the block are in the correct position, the lifting equipment releases the force of lifting the lifting ear. At this time, under the action of the spring, the lifting plate, the movable column and the block are driven to move downward. At this time, the blocks on the front and rear sides are respectively blocked at the front and rear sides of the annular support plate, so that the block is stuck in the positioning groove, and then the position of the installation tube is fixed. The lifting and installation is more convenient, which improves the installation speed of the fan and the base. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Please refer to Figure 1-6 As shown, the utility model provides an adjustable large-scale fan installation base, including a base 1, an arc-shaped limit groove 2 is opened on the surface of the base 1, a limit clamping plate 3 is slidably installed inside the arc-shaped limit groove 2, and adjustment components for driving the limit clamping plate 3 to move are arranged on both sides of the base 1, an annular support plate 6 is installed on the top surface of the limit clamping plate 3, and a mounting cylinder 8 is installed through the inner side of the annular support plate 6, and a fan 9 is installed inside the mounting cylinder 8;

[0025] A positioning groove 7 is provided on the top of the annular support plate 6, and a block 10 passing through the positioning groove 7 is installed on the top of the installation tube 8. Installation grooves 11 are provided on both sides of the block 10. Two movable columns 12 are installed on the top of the block 10 for sliding through. An elastic component connected to the inner wall of the installation groove 11 is provided at the lower end of the movable column 12, and a plurality of blocks 16 are installed on one side of the movable column 12. A lifting connector is provided on the top of the movable column 12.

[0026] Specifically, during hoisting, the hoisting connector is lifted, and the movable column 12 moves upward relative to the block 10, so that when the block 10 enters the positioning groove 7, the block 16 will not block the annular support plate 6. After loosening the hoisting connector, the elastic component pulls the movable column 12 and the block 16 to reset, so that the block 16 blocks the front and rear sides of the annular support plate 6, thereby completing the installation of the installation cylinder 8 and the fan 9.

[0027] Wherein: the adjustment component includes two hydraulic push rods 4, the two hydraulic push rods 4 are fixedly installed on both sides of the base 1 respectively, the output end of the hydraulic push rod 4 passes through the base 1 to the arc-shaped limit groove 2, and the output end of the hydraulic push rod 4 is fixedly installed with a resistance block 5, the resistance block 5 resists the two sides of the limit card plate 3, and the resistance block 5 is driven to move by controlling the hydraulic push rod 4. Under the condition of keeping the limit card plate 3 between the two resistance blocks 5, the limit card plate 3 is controlled to move in the arc-shaped limit groove 2, thereby adjusting the position of the annular support plate 6 and the mounting cylinder 8.

[0028] The elastic component includes a lifting plate 13 , which is welded to the bottom of the movable column 12 , and a spring 14 is fixedly installed at the bottom of the lifting plate 13 . One end of the spring 14 away from the lifting plate 13 is fixedly installed on one side of the installation slot 11 .

[0029] Among them: the spacing between the blocks 16 installed on the surfaces of the movable columns 12 on both sides matches the width dimension of the annular support plate 6. When the blocks 16 on both sides are stuck on the outside of the annular support plate 6, the blocks 10 and the installation tube 8 cannot move forward and backward.

[0030] The lifting connector is specifically two lifting ears 15 , which are respectively mounted on the tops of the two movable columns 12 , and the lifting equipment lifts the installation tube 8 through the two lifting ears 15 .

[0031] The width of the clamping block 10 matches the width of the positioning slot 7 , and the clamping block 10 can just pass through the positioning slot 7 .

[0032] Working principle: The utility model is an adjustable large-scale fan installation base. During hoisting, the hoisting equipment pulls the movable column 12 upward through the hoisting ear 15, so that the lifting plate 13 contacts the inner top of the installation groove 11, thereby pulling the clamping block 10 and the installation tube 8 to be hoisted. After the installation tube 8 is hoisted into the annular support plate 6, the clamping block 10 is just inserted into the positioning groove 7. After the installation tube 8 and the clamping block 10 are in the correct position, the hoisting equipment releases the force of lifting the hoisting ear 15. At this time, under the action of the spring 14, the lifting plate 13, the movable column 12 and the block 16 are driven to move downward. At this time, the block 16 on the front and rear sides are respectively blocked at the front and rear sides of the annular support plate 6, so that the block 10 is stuck in the positioning groove 7, and then the position of the installation tube 8 is fixed. The hoisting installation is more convenient, which improves the installation speed of the fan and the base.

[0033] By controlling the movement of the output end of the hydraulic push rod 4, the positions of the two resistance blocks 5 are changed, so that the resistance block 5 can keep the limit card plate 3 between the two resistance blocks 5 while moving, so that the limit card plate 3 can slide inside the arc limit groove 2. Since the arc limit groove 2 is arc-shaped, the limit card plate 3 can change the angle when driving the annular support plate 6 to move, thereby driving the fan 9 to change the angle through the installation tube 8, thereby improving the flexibility of the fan and the base.
