Description

Technical Field

[0001] The utility model relates to the technical field of hangers, in particular to a hanger for installing a boiler hanger rod. Background Art

[0002] During the installation of large boilers in power plants, the booms are key components for supporting and fixing the boilers. Their installation accuracy and efficiency directly affect the overall structural stability and construction progress of the boilers. When installing traditional booms, most cranes are used to hoist a single boom, and then the booms are manually assembled to the designated installation position. The overall installation speed is slow. If multiple booms are hoisted at one time, it is easy for the booms to collide with each other during the hoisting process. The collision will cause the booms to deform and be damaged, thus affecting their stability in subsequent use in the boiler. To this end, we propose a boiler boom installation hanger.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The utility model provides a technical solution: a boiler boom installation hanger, including a fixing frame 1, the top of the fixing frame 1 is symmetrically welded with lifting rings 2 on the left and right, and the setting of the lifting rings 2 is convenient for connecting the fixing frame 1 with lifting mechanical equipment such as a crane or a hoist, so that the boiler boom can be lifted.

[0022] The fixing frame 1 is uniformly integrally formed with mounting blocks 3 from left to right. The mounting blocks 3 can be provided with corresponding numbers according to the specific hoisting requirements during the hoisting process. The mounting block 3 is provided with a mounting cavity 4, which is composed of an upper cavity 41, a locking groove 42 and a lower cavity 43 arranged in sequence from top to bottom. The upper cavity 41 is connected to the lower cavity 43 through the locking groove 42. A connecting frame 5 is installed in the lower cavity 43. A locking assembly 6 for locking the connecting frame 5 is installed in the upper cavity 41. A clamping frame 7 is installed at the bottom of the connecting frame 5. The clamping frame 7 is used to clamp and fix the boiler boom during the lifting process. The clamping frame 7 is connected to the fixing frame 1 by setting a connecting frame 5. The clamping frame 7 can change the movement direction through the connecting frame 5, so as to facilitate the assembly of the boiler boom to the specified installation position. At the same time, during the lifting of the boiler boom, the connecting frame 5 can be locked by the locking assembly 6 to avoid collision between the suspended boiler booms during the lifting process, thereby avoiding damage to the boiler boom and affecting the subsequent use of the boiler boom.

[0023] like Figure 2 and Figure 3As shown in the figure, the connecting frame 5 includes a connecting rod 51, and a connecting ball 52 is fixedly connected to the top of the connecting rod 51. The connecting ball 52 is rotatably connected in the lower cavity 43. The size of the lower cavity 43 is adapted to the size of the connecting ball 52. By rotating the connecting ball 52 and the lower cavity 43, the connecting frame 5 can be adjusted to various angles. A locking portion 53 is integrally formed on the top of the connecting ball 52, and the locking portion 53 is arranged in a plane. Through the action of the locking assembly 6, the connecting ball 52 and the lower cavity 43 can be locked, so that the connecting frame 5 can remain stable during the lifting process. A connecting ring 54 is fixedly connected to the bottom of the connecting rod 51, and the connecting ring 54 is used to be assembled with the clamping frame 7.

[0024] like Figure 2 As shown in the figure, the locking assembly 6 includes an electromagnet 61, which is a push-pull electromagnet. The electromagnet 61 is electrically connected to an external power supply and an external controller. The action of the output end of the electromagnet 61 can be controlled by the external controller. The output end of the electromagnet 61 is fixedly connected with a locking pin 62 that is slidably connected to the locking groove 42. The locking pin 62 can be driven by the electromagnet 61 to move in the locking groove 42 and the lower cavity 43. When the locking pin 62 is tightly fitted with the locking portion 53 downward, the locking operation of the connecting ball 52 can be realized in the lower cavity 43. The setting of the locking portion 53 can increase the locking effect of the locking pin 62 on the connecting ball 52.

[0025] like Figure 4 and Figure 5 As shown in the figure, the clamping frame 7 includes a clamping frame body 71, the top of the clamping frame body 71 is rotatably connected to the connecting ring 54, and the clamping frame 7 can be rotated along the limited direction of the connecting ring 54. The bottom of the clamping frame body 71 is provided with a clamping groove 72, and the side wall of the clamping groove 72 is provided with an assembly groove 73. A clamping block 74 is slidably connected in the assembly groove 73. A driving motor 75 is embedded and installed in the side wall of the clamping frame body 71. A driving screw 76 is screwed in the side wall of the clamping block 74. The output end of the driving motor 75 is fixedly connected to the end of the driving screw 76 through a coupling, and the top of the clamping block 74 is fixedly connected to The limit blocks 77 are symmetrically distributed at the front and rear, and the limit blocks 77 are slidably connected in the limit grooves 78. The limit shafts 79 penetrating the limit blocks 77 are fixedly connected in the limit grooves 78. By setting the limit shafts 79 and the limit blocks 77, the driving motor 75 can adjust the position of the clamping block 74 in the clamping grooves 72 and the assembly grooves 73 during the process of driving the driving screw 76 to rotate, so that the clamping frame 7 can clamp and fix the boiler boom. At the same time, the limit grooves 78 limit the limit blocks 77, and can also limit the moving stroke of the clamping block 74 to avoid the separation between the driving screw 76 and the clamping block 74.

[0026] The driving motor 75 is electrically connected to an external power supply and an external controller. The driving motor 75 is a pulse stepping motor. The external controller can control each driving motor 75 to perform independent actions. By sending a pulse signal to the driving motor 75 through the external controller, the output end of the driving motor 75 can be controlled. By the forward or reverse rotation of the output end of the driving motor 75, the telescopic operation of the clamping block 74 in the clamping groove 72 can be realized.

[0027] The clamping block 74 and the opposite side walls of the clamping groove 72 are respectively fixedly connected with rubber pads 8. By providing the rubber pads 8, the friction between the clamping groove 72, the clamping block 74 and the boiler boom can be increased, further enhancing the clamping and limiting effect on the boiler boom.

[0028] Working principle: Figure 1 and Figure 6 As shown in , when the utility model is hoisting the boiler boom, the lifting ring 2 is connected and fixed to the wire rope of the crane, and then the output end of the driving motor 75 is controlled to rotate by the external controller, and the clamping block 74 is retracted into the assembly groove 73, and the annular body at the top of the boiler boom is placed in the clamping groove 72, and then the external controller controls the driving motor 75 to move in the opposite direction, so that the clamping block 74 cooperates with the clamping groove 72 to clamp and fix the boiler boom, and the bottom of the clamping block 74 will penetrate the annular body of the boiler boom. During the hoisting process, the boiler boom can be lifted by the clamping block 74. After the boiler booms are connected to each clamping frame 7 in turn, multiple boiler booms can be hoisted together. The locking pin 62 in the locking assembly 6 moves downward to lock the connecting ball 52, so that the boiler hanger can only move along the limited direction of the clamping frame 7 and the connecting ring 54 during the lifting process, and no collision will occur between the boiler hangers, thereby avoiding deformation and damage of the boiler hanger during the lifting process. After the boiler hanger is lifted to the specified installation position, the electromagnet 61 controls the locking pin 62 upward, and the locking pin 62 no longer locks the connecting ball 52. At this time, the installer can adjust the boiler hanger to a suitable installation position by holding the boiler hanger, and then control the movement of the clamping block 74 in the corresponding clamping frame 7, so that the boiler hanger can be taken out of the clamping frame 7 and assembled to the specified installation position.
