Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1 to 3 As shown, this embodiment provides a chiseling device for reinforcing bridge abutment plates, including a base 1, a lifting frame, an operating rod 2, and a chiseling machine body 3. The base 1 is detachably installed on the top of the fence of the work platform, the lifting frame is set on the base 1, the front end of the operating rod 2 is connected to the rear end of the lifting frame, and the chiseling machine body 3 is installed on the front end of the lifting frame. The lifting frame can control the height of the chiseling machine body 3.

[0020] The chipping machine 3 is installed on the top of the fence of the work platform by means of the base 1, the lifting frame and the operating frame. The work platform supports the chipping machine 3, which can reduce the intensity of manual work. At the same time, the chipping machine 3 can move along the bridge bottom surface with the movement of the work platform to realize the chipping operation of the bridge bottom surface.

[0021] During the roughening operation of the bridge underside, workers can control the lifting frame via the operating lever 2 to adjust the height of the roughening machine 3, thereby controlling the roughening effect in real time.

[0022] Specifically, in this embodiment, the lifting frame includes a placement frame 4 for placing the chisel body 3 and a parallelogram-shaped frame 5 that can control the lifting and lowering of the placement frame 4. The placement frame 4 is connected to the front vertical side of the frame 5, the base 1 is located at the bottom of the rear vertical side of the frame 5, and the operating lever 2 is located at the rear end of the top side of the frame 5.

[0023] The placement frame 4 has a square frame structure with an open top, and its internal dimensions are designed to fit the chisel body 3 for better fixation. Pressure plates are provided on both sides of the top of the placement frame 4 to press the chisel body 3 firmly within it, and these pressure plates are bolted to the placement frame 4. This design facilitates the installation and fixation of the chisel body 3 within the placement frame 4 or its removal from it.

[0024] The vertical sides at the front end of the frame 5 can be directly fixed to the placement rack 4 by welding. Of course, in other embodiments, a bolting method can also be used, which is not limited herein.

[0025] In this embodiment, the frame 5 includes two quadrilateral brackets arranged symmetrically left and right, and there are two operating rods 2. The front ends of the two operating rods 2 are respectively fixed to the rear ends of the top sides of the two parallelogram brackets. The bottoms of the two vertical sides at the rear end of the frame 5 are fixed together by a connecting plate, so that the two vertical sides at the rear end of the frame 5 form a "匚"-shaped structure with the opening facing upwards, and the base 1 is fixed to the connecting plate.

[0026] Specifically, in this embodiment, a connecting sleeve 6 is provided at the rear end of the top side of the frame 5 and is rotatably connected to the top end of the vertical side at the rear end of the frame 5. A ratchet plate 7 arranged longitudinally is fixedly provided on the vertical side at the rear end of the frame 5. The tooth pressure of the ratchet plate 7 is set to face backwards. A catch 8 is engaged with the rear side of the ratchet plate 7. The top end of the catch 8 bends forward and is rotatably connected to the surface of the connecting sleeve 6, and both the ratchet plate 7 and the catch 8 are located behind the rotation center of the top side and the rear vertical side of the frame 5.

[0027] The connecting sleeve 6 effectively connects the catch 8 to the top side of the frame 5. Under the action of its own weight, the bottom end of the catch 8 will swing forward, and thus it can be clamped into the ratchet plate 7 by using its own weight. The teeth on the ratchet plate 7 are set such that the bottom edge is a plane and the rear side is an inclined plane with the top end inclined forward. The hook head of the catch 8 is set in a state opposite to the teeth. After the catch 8 is inserted into the ratchet plate 7, the ratchet plate 7 can prevent the catch 8 from moving upward, and thus the top side of the frame 5 is limited by the catch 8 to prevent the top side of the frame 5 from swinging downward, so as to fix the scarifying machine body 3 at the adjusted height. Specifically, when adjusting the height of the scarifying machine downward, manually pull the catch 8 out of the ratchet plate 7, and then the worker holds the operating rod 2 by hand and slowly releases the operating rod 2 upward.

[0028] In order to further improve the fixing of the height of the scarifying machine body 3 by the cooperation of the catch 8 and the ratchet plate 7, a rotating sleeve 9 rotatably matched with the connecting sleeve 6 is fixedly provided at the top end of the catch 8. An elastic telescopic rod 10 is rotatably connected between the rotating sleeve 9 and the connecting sleeve 6. The elastic force of the elastic telescopic rod 10 can clamp the catch 8 more stably on the ratchet plate 7.

[0029] In this embodiment, the base 1 includes a bottom plate 1.1, a track 1.2 and a track wheel 1.3. The bottom end of the vertical side at the rear end of the frame 5 is connected to the bottom plate 1.1. The track 1.2 is detachably installed on the top of the fence of the working platform. The track wheel 1.3 is installed at the bottom of the bottom plate 1.1, and the track wheel 1.3 is located inside the track 1.2.

[0030] Specifically, the bottom of the connecting plate is connected to the base plate 1.1. The displacement of the track 1.2 within the track wheel 1.3 allows the worker to move the roughening machine along the length of the track 1.2, thus roughening the bridge bottom surface. During construction, the worker first fixes the track 1.2 to the top of the work platform's railing, then slides the track wheel 1.3 into the track from one side of the track 1.2, with the track 1.2 limiting the movement of the track wheel 1.3.

[0031] After adjusting the height of the chiseling machine body 3 to a suitable level using the operating lever 2, the chiseling machine body 3 is fixed at the adjusted height using the hook and ratchet plate 7. After starting the chiseling operation, the worker can push and pull the operating lever 2 laterally to move the chiseling machine along the length of the track 1.2, thereby achieving chiseling operations on various parts of the bridge bottom surface.

[0032] Furthermore, the bottom of the vertical edge at the rear end of frame 5 is rotatably engaged with the base plate 1.1 via a support shaft 11. Using the support shaft 11, the chiseling machine body 3 can rotate around the support shaft 11 below the bridge bottom surface, allowing workers to control the chiseling machine more flexibly and improving chiseling efficiency.

[0033] Specifically in this embodiment, side plates 12 are installed on both the front and rear sides of the track 1.2. A clamping plate 13 is provided between the rear side plate 12 and the top of the fence of the working platform. Two tightening bolts 14 are threaded on the rear side plate 12, and the tightening bolts 14 are rotatably engaged with the clamping plate 13.

[0034] When installing track 1.2, first, place the side plates 12 on the front and rear sides of the front and rear sides of the top of the fence of the work platform from top to bottom. Then, rotate the clamping bolt 14. When the clamping bolt 14 moves forward, it drives the clamping plate 13 to squeeze the fence, so that the clamping plate 13, together with the side plates 12, firmly fixes the track 1.2 to the fence. This makes the installation and disassembly of track 1.2 extremely convenient and facilitates construction operations.

[0035] A single-ended bolt 15 is fixedly installed on the surface of the track 1.2. The side plate 12 is sleeved on the single-ended bolt 15, and a fastening nut 16 is provided on the outside of the single-ended bolt 15 to press the side plate 12 into the surface of the track 1.2. The single-ended bolt 15 and the fastening nut 16 make the connection between the side plate 12 and the track 1.2 detachable, which facilitates the assembly and disassembly operations on the construction site.

[0036] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
