Description

Technical Field

[0001] This utility model relates to the field of grate bar processing technology, specifically a fixing frame for grate bar processing. Background Technology

[0002] A grate is a component in a boiler or industrial furnace that holds and efficiently combusts solid fuel. The grate mainly consists of two parts: the frame and the grate bars. The grate bars are typically made of cast iron. After assembly, necessary ventilation gaps are maintained between the bars, and often, adjustable ventilation chambers are installed under the grate to allow air to enter the fuel bed through these gaps. The ash and slag after combustion are then removed manually or mechanically.

[0003] Currently, in the market, during the processing of grate bars, a fixing frame is needed to secure the grate bars. However, the existing grate bar fixing frames have a relatively simple structure, which is fixed by simple fasteners. This results in the fasteners not being securely fixed, causing the grate bars to shift during processing, leading to processing errors and affecting later use.

[0004] As disclosed in Chinese Patent CN216883479U, a fixing frame for grate bar processing relates to the field of grate bar processing technology. This utility model includes a mounting base, with a support column connected to the top of the mounting base via a movable component. A fixing component is mounted on the support column. The fixing component includes a fixing frame, a positioning cylinder, a moving rod, a first connecting rod, a second connecting rod, a sector gear, a spring, a rack, and a clamping plate. The fixing frame is fixedly connected to the support column, and the positioning cylinder is fixedly connected to the inner wall of the fixing frame. One end of the moving rod is movably disposed inside the positioning cylinder. The spring is sleeved on the outer surface of the moving rod, with one end of the spring fixedly connected to the side of the positioning cylinder and the other end of the spring fixedly connected to the side of the moving rod. The first connecting rod is movably connected to the other end of the moving rod. This utility model is a fixing frame for grate bar processing. By setting the fixing component, it facilitates better positioning of the grate bars and prevents displacement during processing.

[0005] However, the forging force is very large during the processing of grate plates. The device is fixed by the action of gears and racks, which may be damaged during forging, resulting in an unstable fixation.

[0006] To address this issue, we propose a fixing frame for grate bar processing. Utility Model Content

[0007] The purpose of this utility model is to provide a fixing frame for processing grate bars, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a fixing frame for processing grate bars, including a worktable, wherein a fixing mechanism is provided on the surface of the worktable and a buffer mechanism is provided at the bottom of the worktable.

[0009] The fixing mechanism includes a second support column, a mounting plate, a circular groove, a second telescopic cylinder, a push plate, a connecting block, a connecting rod, and a circular movable plate. The second support column is fixedly installed on the surface of the workbench. The mounting plate is fixedly installed on the top of the second support column. The second telescopic cylinder is fixedly installed on the bottom of the mounting plate. The output end of the second telescopic cylinder is connected to the push plate. The surface of the push plate is fixedly installed with the connecting block. The connecting rod is rotatably installed on the surface of the connecting block. The circular groove is formed on the surface of the mounting plate. The circular movable plate is installed inside the circular groove. The other end of the connecting rod is rotatably installed on the surface of the circular movable plate.

[0010] Preferably, a telescopic block is fixedly installed on the surface of the connecting block, and the other end of the telescopic block is installed on the side of the mounting plate, so as to facilitate the second telescopic cylinder to pull the connecting block to play a connecting role. The connecting block is L-shaped, so that multiple surfaces can be installed.

[0011] Preferably, a support column is fixedly installed on the surface of the workbench, and a processing plate is fixedly installed on the top of the support column. A groove is opened at the edge of the surface of the processing plate.

[0012] Preferably, a clamping block is fixedly installed on the upper surface of the connecting block. The clamping block is distributed inside the groove on the surface of the processing plate, so that the clamping block has space to move, thereby clamping and fixing the grate plate.

[0013] Preferably, the buffer mechanism includes a base, a buffer hole, a telescopic damping column, and a buffer spring. The telescopic damping column is fixedly installed at the bottom end of the workbench, the buffer spring is connected to the bottom end of the workbench, the other end of the telescopic damping column is fixedly installed on the bottom surface of the buffer hole, the buffer hole is opened on the surface of the base, and the other end of the buffer spring is connected to the bottom surface of the buffer hole.

[0014] Preferably, the diameter of the buffer hole is larger than the diameter of the buffer spring, and the buffer spring is sleeved on the outer surface of the telescopic damping column. When the grate is forged, the worktable will be subjected to a great force, causing the telescopic damping column and the buffer spring to extend and retract into the buffer hole, thereby buffering the worktable and protecting the structure on the worktable.

[0015] Preferably, a fixed column is fixedly installed on the surface of the workbench, a support plate is fixedly installed on the top of the fixed column, a telescopic cylinder is fixedly installed on the surface of the support plate, and a hammer is connected to the output end of the telescopic cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This grate bar processing fixing frame, through the setting of a fixing mechanism, places the grate bar on the processing plate. Activating the second telescopic cylinder drives the push plate, causing the connecting block and clamping block mounted on the push plate to move accordingly. This causes the connecting rod mounted on the surface of the connecting block to rotate, and consequently, the circular movable plate mounted on the other end of the connecting rod rotates within a circular groove on the mounting plate. The connecting rod is configured with four sets, and all four sets operate simultaneously, ultimately achieving a clamping and fixing effect on the grate bar. This solves the problem mentioned in the background technology where the forging force during grate bar processing is very high, and the device's fixation via gears and racks may be damaged during forging, resulting in insecure fixing.

[0017] 2. The grate plate processing fixture is equipped with a buffer mechanism. When the No. 1 telescopic cylinder drives the hammer to forge the grate plate on the processing plate, the worktable moves downward due to pressure. This causes the telescopic damping column and buffer spring to compress into the buffer hole, thereby reducing the pressure generated during forging, protecting the structure on the worktable, and extending the service life of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: Example 1: A fixing frame for processing grate bars includes a worktable 1, a fixing mechanism is provided on the surface of the worktable 1, and a buffer mechanism is provided at the bottom of the worktable 1.

[0022] The fixing mechanism includes a second support column 403, a mounting plate 404, a circular groove 405, a second telescopic cylinder 406, a push plate 407, a connecting block 408, a connecting rod 411, and a circular movable plate 412. The second support column 403 is fixedly installed on the surface of the workbench 1. The mounting plate 404 is fixedly installed on the top of the second support column 403. The second telescopic cylinder 406 is fixedly installed on the bottom of the mounting plate 404. The output end of the second telescopic cylinder 406 is connected to the push plate 407. The connecting block 408 is fixedly installed on the surface of the push plate 407. The connecting block 408 is L-shaped, allowing for installation on multiple surfaces. The connecting rod 411 is rotatably installed on the surface of the connecting block 408. A telescopic block 409 is fixedly installed on the surface of the connecting block 408. The other end of 409 is installed on the side of the mounting plate 404, which facilitates the second telescopic cylinder 406 to pull the connecting block 408 to perform the connecting function. A circular groove 405 is opened on the surface of the mounting plate 404, and a circular movable plate 412 is installed inside the circular groove 405. The other end of the connecting rod 411 is rotatably installed on the surface of the circular movable plate 412. A first support column 401 is fixedly installed on the surface of the workbench 1, and a processing plate 402 is fixedly installed on the top of the first support column 401. A groove is opened at the edge of the surface of the processing plate 402. A clamping block 410 is fixedly installed on the upper surface of the connecting block 408. The clamping blocks 410 are distributed inside the groove on the surface of the processing plate 402, so that the clamping blocks 410 have room to move, thereby clamping and fixing the grate bars.

[0023] Example 2: Based on Example 1, the buffer mechanism includes a base 201, a buffer hole 202, a telescopic damping column 203, and a buffer spring 204. The telescopic damping column 203 is fixedly installed at the bottom of the workbench 1, and the buffer spring 204 is connected to the bottom of the workbench 1. The other end of the telescopic damping column 203 is fixedly installed on the inner bottom surface of the buffer hole 202. The buffer hole 202 is opened on the surface of the base 201, and the other end of the buffer spring 204 is connected to the inner bottom surface of the buffer hole 202. The diameter of the buffer hole 202 is larger than the diameter of the buffer spring 204. The buffer spring 204 is sleeved on the outer surface of the telescopic damping column 203. When the grate is forged, the workbench 1 will be subjected to a large force, causing the telescopic damping column 203 and the buffer spring 204 to extend and retract into the buffer hole 202, thereby buffering the workbench 1 and protecting the structure on the workbench 1.

[0024] Example 3: Based on Example 1, a fixed column 301 is fixedly installed on the surface of the workbench 1, a support plate 302 is fixedly installed on the top of the fixed column 301, a first telescopic cylinder 303 is fixedly installed on the surface of the support plate 302, and a hammer head 304 is connected to the output end of the first telescopic cylinder 303.

[0025] Working principle: During use, the grate plate is placed on the processing plate 402. The second telescopic cylinder 406 is activated to drive the push plate 407, causing the connecting block 408 and the clamping block 410 installed on the connecting block 408 to move as well. This causes the connecting rod 411 installed on the surface of the connecting block 408 to rotate, which in turn causes the circular movable plate 412 installed at the other end of the connecting rod 411 to rotate in the circular groove 405 on the mounting plate 404. The connecting rod 411 is set in four groups, and when it is activated, the four groups of structures move together, ultimately achieving the clamping and fixing effect of the grate plate. After the grate plate is fixed, the first telescopic cylinder 303 is activated to drive the hammer 304 to forge the grate plate on the processing plate 402. During forging, the worktable 1 moves downward due to pressure, which causes the telescopic damping column 203 and the buffer spring 204 to compress into the buffer hole 202, thereby reducing the pressure generated during forging, protecting the structure on the worktable 1, and extending the service life of the device.
