Description

Technical Field

[0001] This utility model relates to the field of boiler installation and maintenance equipment technology, and in particular to a three-dimensional adjustable boiler steel structure component positioning bracket. Background Technology

[0002] The manufacturing and on-site installation of large boilers involves the precise assembly and welding of numerous large and heavy steel structural components. In order to ensure the structural accuracy and operational safety of the final boiler body, the independent steel structural components must be adjusted to the precise design position in three-dimensional space by support and positioning equipment before they are permanently fixed.

[0003] Therefore, the industry typically uses various types of positioning brackets. Positioning brackets generally have adjustment functions in three directions: longitudinal, lateral, and vertical, to meet basic positioning requirements. However, in practical applications, the lateral adjustment capability of these traditional positioning brackets is often limited by the width of their own structure, and the lateral travel range is fixed or can only be finely adjusted within a limited range.

[0004] However, the specifications and dimensions of boiler steel structure components are not fixed. Different models of boilers, and even different parts of the same boiler, have huge differences in component width. When encountering wide components that exceed the lateral adjustment range of conventional supports, existing equipment is powerless. On the other hand, for narrower components, using large fixed-width supports would be cumbersome and have low space utilization. This inherent structural limitation results in poor versatility of existing positioning supports, making it impossible to flexibly adapt to changing construction needs and seriously affecting installation efficiency.

[0005] Therefore, this utility model proposes a three-dimensional adjustable boiler steel structure component positioning bracket to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems existing in the three-dimensional adjustable boiler steel structure component positioning bracket, such as limited lateral adjustment range, difficulty in adapting to components of different widths, and insufficient locking reliability and safety of the vertical lifting mechanism under heavy load, this utility model aims to provide a three-dimensional adjustable boiler steel structure component positioning bracket with improved structure that can effectively solve the above problems.

[0007] This utility model provides a three-dimensional adjustable boiler steel structure component positioning bracket, including a base plate, at least two lifting columns set on the base plate, a slide rail mounted on the lifting columns, and a moving block slidably connected to the slide rail; it also includes an extension mechanism set between the lifting columns and the slide rail, and a fixing mechanism for locking the lifting columns. The expansion mechanism has a structure that can change the lateral span, consisting of a main board with a slot and a telescopic plate that can be slidably housed in the slot. The end of the telescopic plate is fixedly connected to a limit plate, and the slide rail is mounted on the top surface of the main board and the telescopic plate, so that the effective lateral sliding stroke of the slide rail can be adjusted according to the extension amount of the telescopic plate. Furthermore, the fixing mechanism and the lifting column are combined in a selective rigid locking manner; specifically, a slot is provided on the outer wall of the lifting column, and the fixing mechanism includes a column adjacent to the lifting column, a connecting ring fixedly connected to the column, and a locking plate slidably installed on the connecting ring and selectively inserted into the slot. The locking plate and the slot cooperate to achieve reliable locking of the lifting column in the vertical position.

[0008] Preferably, the main board of the expansion mechanism is also fixedly connected to a guide plate on the inner wall of the slot, and the side of the telescopic plate and the surface of the guide plate form a sliding contact fit, which effectively prevents the telescopic plate from deflecting or getting stuck during movement.

[0009] Preferably, the extension mechanism further includes a locking component; the locking component consists of a latch rotatably connected to the main board and a buckle fixed to the telescopic plate. By operating the latch and buckle to engage and disengage, the telescopic plate can be easily locked or unlocked at any extended position.

[0010] Preferably, the fixing mechanism further includes a fixing pin; both the connecting ring and the locking plate are provided with through holes that can be aligned with each other. When the locking plate is fully inserted into the slot, the fixing pin is inserted into the aligned through hole to form a firm mechanical limit, eliminating the risk of accidental slippage.

[0011] Preferably, the three-dimensional adjustable boiler steel structure component positioning bracket further includes a longitudinal drive component; the longitudinal drive component adopts a gear and rack transmission method, specifically, a rack is set inside the slide rail, and a gear that meshes with the rack is rotatably installed on the moving block. By driving the gear to rotate, the moving block can be moved smoothly and accurately along the length direction of the slide rail.

[0012] Preferably, the three-dimensional adjustable boiler steel structure component positioning bracket further includes a transverse drive assembly; the transverse drive assembly has gears respectively set below both ends of the slide rail, and a rack is correspondingly laid on the top surface of the main board of the extension mechanism. By synchronously driving the two gears to rotate, the stability and accuracy of the slide rail during transverse translation are ensured.

[0013] Preferably, in order to realize the lifting drive of the lifting column, the driving method of the lifting column also adopts gear and rack transmission; specifically, a vertically extending rack is machined on the side wall of the lifting column, and a gear that meshes with the rack is provided as the core of the vertical drive component. The lifting column can be driven to move in the vertical direction by rotating the gear.

[0014] Preferably, the power source of the vertical drive assembly is a manual operating handle; the manual operating handle is fixed on the column and connected to the gear driving the lifting column through an internal transmission mechanism, so that the operator can control the lifting of the entire upper platform in a labor-saving and stable manner by manually turning the handle.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem that the existing positioning bracket has a fixed lateral adjustment range and is difficult to adapt to components of different widths by setting an expansion mechanism consisting of a main board and a sliding and telescopic plate. It effectively expands the lateral working range of the bracket and can improve the versatility and flexibility of the equipment.

[0016] 2. This utility model solves the problem that existing lifting supports rely solely on the transmission system for positioning under heavy loads, which poses a safety hazard, by setting up a fixing mechanism consisting of a locking plate, a locking groove, and a fixing pin working together. It can provide double mechanical locking for the lifting column, improving the load-bearing stability and safety of the support.

[0017] 3. This utility model solves the problems of cumbersome operation and poor coordination of adjustments in all directions when positioning large components in three dimensions by integrating the longitudinally sliding moving block, the slide rail that can slide laterally on the expansion mechanism, and the vertically moving lifting column into an integrated design.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model. Example

[0021] Please refer to Figures 1 to 5 The three-dimensional adjustable boiler steel structure component positioning bracket includes a base plate 1 as an installation base, at least two lifting columns 5 that are raised and lowered on the top of the base plate 1, a slide rail 6 mounted on the top of the lifting columns 5, and a moving block 4 slidably connected to the slide rail 6. The basic frame provides a basic platform for the movement and positioning of components in three-dimensional space. To achieve flexible lateral expansion and reliable vertical locking, the three-dimensional adjustable boiler steel structure component positioning bracket also includes an expansion mechanism 2 and a fixing mechanism 3.

[0022] Reference Figure 2 and Figure 3 An extension mechanism 2 is located between the lifting column 5 and the slide rail 6 to widen the lateral travel range of the slide rail 6. The extension mechanism 2 includes a main board 201 with a slot 204. A telescopic plate 202 is slidably housed inside the slot 204 of the main board 201. A limit plate 203 is fixedly connected to the end of the telescopic plate 202 away from the main board 201. When the telescopic plate 202 is fully extended, the limit plate 203 abuts against the opening of the slot 204, thereby preventing the telescopic plate 202 from exiting the main board 201. 1. To ensure smooth sliding of the telescopic plate 202, a guide plate 205 is fixedly connected to the inner wall of the slot 204 on the main board 201. To lock the telescopic plate 202 in a specific position, the expansion mechanism 2 also includes a locking block 206 rotatably connected to the main board 201, and a buckle 207 fixed to the telescopic plate 202 and used to cooperate with the locking block 206. The slide rail 6 is mounted on the top surface of the main board 201 and the telescopic plate 202, and the lateral sliding range increases as the telescopic plate 202 extends.

[0023] Reference Figure 5The fixing mechanism 3 is used to rigidly lock the lifting column 5 after it is adjusted to a predetermined height. The outer wall of the lifting column 5 is provided with a locking groove 303. The fixing mechanism 3 includes a column 301 located adjacent to the lifting column 5. The column 301 is fixedly connected to the base plate 1. The connecting ring 302 is fixedly connected to the upper part of the column 301. The locking plate 304 is slidably installed on the connecting ring 302. The locking plate 304 can move in the horizontal direction and can selectively insert into or disengage from the groove 303 on the lifting column 5. In order to achieve a final secure lock, the fixing mechanism 3 also includes a fixing pin 305. The connecting ring 302 and the locking plate 304 are provided with through holes that can be aligned with each other. After the locking plate 304 is inserted into the groove 303, the fixing pin 305 can be inserted into these through holes to prevent the locking plate 304 from accidentally coming out.

[0024] Please refer to Figure 1 , Figure 4 and Figure 5 The longitudinal positioning adjustment is achieved by a longitudinal drive component, which drives the moving block 4 to slide back and forth along the length of the slide rail 6. Specifically, a rack is provided inside the slide rail 6, and a gear 7 is rotatably mounted on the moving block 4 and meshes with the rack. When an external power drives the gear 7 to rotate, the moving block 4 will move precisely to the specified longitudinal position along the outer wall of the slide rail 6 under the meshing action of the gear 7 and the rack. The lateral positioning adjustment is achieved by a lateral drive component, which drives the entire slide rail 6 to slide laterally on the top surface of the extension mechanism 2. Specifically, gears 7 are provided at the bottom of both ends of the slide rail 6, and a rack is correspondingly provided on the top surface of the main board 201 of the extension mechanism 2. The gears 7 at both ends of the slide rail 6 mesh with the rack on the main board 201. By synchronously driving the two gears 7 to rotate, the slide rail 6 and the moving block 4 can be moved laterally as a whole, thereby adjusting the lateral position. Please refer to Figure 4 and Figure 5 The vertical lifting adjustment is achieved by a vertical drive assembly, which drives the lifting column 5 to move vertically. Specifically, a vertically extending rack is provided on the side wall of the lifting column 5, and a drive gear 7 meshing with it is installed on the bracket structure adjacent to the lifting column 5. The vertical drive assembly also includes a manual operating handle fixed on the column 301. The manual operating handle is connected to the gear 7 used to drive the lifting column 5 to rise or fall through a transmission mechanism. By turning the handle, the operator can smoothly drive the lifting column 5 to rise or fall, thereby realizing the overall height adjustment of the entire upper positioning platform.

[0025] As a preferred embodiment of the structure of the extension mechanism 2, in order to ensure the smoothness and stability of the telescopic plate 202 during the extension or retraction process, the main plate 201 is fixedly connected to the inner wall of the slot 204 with a guide plate 205. The guide plate 205 is a long strip structure with a smooth surface, extending along the length direction of the slot 204. The side of the telescopic plate 202 slides in contact with the surface of the guide plate 205. Through this surface contact guiding method, the telescopic plate 202 is effectively prevented from swaying or getting stuck during the movement.

[0026] As a preferred embodiment of the locking function of the extension mechanism 2, in order to reliably fix the extension position of the telescopic plate 202, a locking block 206 is rotatably connected to the main board 201, and a buckle 207 is fixed at the corresponding position of the telescopic plate 202; when the telescopic plate 202 slides to the predetermined position, the user rotates the locking block 206 so that the locking block 206 and the buckle 207 engage with each other, thereby firmly locking the telescopic plate 202 in the current position and preventing accidental relative sliding when bearing a load.

[0027] As a preferred embodiment for ensuring the locking reliability of the fixing mechanism 3, and to provide dual safety assurance, the fixing mechanism 3 is further equipped with a fixing pin 305 for mechanical locking, in addition to the cooperation between the locking plate 304 and the slot 303. Both the connecting ring 302 and the locking plate 304 have through holes that can be aligned with each other. When the locking plate 304 is fully inserted into the slot 303 of the lifting column 5, these through holes will be precisely aligned. At this time, the columnar fixing pin 305 is passed through the through holes of the connecting ring 302 and the locking plate 304 in sequence to form a physical rigid connection, eliminating the risk of the locking plate 304 slipping out of the slot 303.

[0028] Working principle: When performing positioning operations, firstly, the horizontal adjustment is made according to the size and position requirements of the component to be positioned. If the existing width is sufficient, the gears 7 at both ends of the slide rail 6 are driven to rotate directly through the horizontal drive component. The gears 7 mesh with the rack on the main board 201, driving the slide rail 6 to move horizontally to the target position on the top surface of the expansion mechanism 2. If the existing width is insufficient, the expansion mechanism 2 is operated first, rotating and releasing the locking of the locking block 206 and the buckle 207, and pulling the telescopic plate 202 outward until the required width is reached. At this time, the limiting plate 203 prevents the telescopic plate 202 from falling off. Then, the telescopic plate 202 is locked again through the locking block 206 and the buckle 207. After the horizontal expansion is completed, the horizontal fine adjustment of the slide rail 6 is performed. After the lateral position is determined, longitudinal adjustment is performed. The gear 7 installed on the moving block 4 is driven to rotate by the longitudinal drive component. The gear 7 meshes with the rack inside the slide rail 6, thereby driving the moving block 4 to slide precisely along the slide rail 6 to the target longitudinal position. The clamp or platform on the moving block 4 used to support the component then reaches the designated location. Finally, the vertical height is adjusted by rotating the manual operating handle on the fixing mechanism 3. The gear 7 meshing with the rack on the side wall of the lifting column 5 is driven to rotate through the internal transmission mechanism, thereby causing the two lifting columns 5 to rise or fall synchronously until the entire upper platform reaches the predetermined height. After the height is determined, the locking plate 304 of the fixing mechanism 3 is pushed into the corresponding slot 303 of the lifting column 5, and then the fixing pin 305 is inserted into the through hole of the connecting ring 302 and the locking plate 304 to complete the double mechanical locking and ensure that the bracket is absolutely stable and reliable when bearing heavy objects.
