Description

Technical Field

[0001] This application relates to the field of grooving technology, and more specifically, to an adjustable width grooving device for municipal engineering. Background Technology

[0002] The construction of various public infrastructure supporting urban life falls under the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life. When improving water supply and drainage pipelines, road grooving equipment is needed to groove the road surface. However, existing road cutting devices cannot achieve double-sided grooving, resulting in poor grooving effect.

[0003] Existing technology publication (announcement) number CN220335671U provides an adjustable-width grooving device for municipal engineering. In this device, two ball screws on both sides, driven by nuts, can move two movable plates in opposite directions. This, in turn, drives the cutting components on both sides to move in opposite directions, changing the distance between the cutting components and achieving adjustable grooving width. Furthermore, the device employs a single drive source to synchronously drive two ball screws to ultimately achieve adjustable grooving width, offering advantages such as relatively simple structure and correspondingly low cost.

[0004] While the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks: the grooves cut by the two cutting components require manual hammering for removal, resulting in poor grooving performance.

[0005] In view of this, we propose an adjustable width slotting device for municipal engineering. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides an adjustable width slotting device for municipal engineering.

[0007] The adjustable width slotting device for municipal engineering provided in this application adopts the following technical solution:

[0008] An adjustable-width grooving device for municipal engineering includes a mounting frame for installing power supply facilities. The mounting frame has two symmetrically connected crossbars. One of the crossbars is fixed to the mounting frame via bolts. A cutting component is fixedly connected to one side of the crossbar, and a tilting frame is slidably connected between the two crossbars. One end of the tilting frame is abutted against and limited by a fastening handwheel. An electric telescopic rod is fixedly connected between the tilting frame and the crossbar, and a limit frame is fixedly connected to one side of the tilting frame. A crankshaft is rotatably connected inside the limit frame. One end of the crankshaft passes through the limit frame and is fixedly connected to a drive motor. The drive motor is fixedly connected to the side wall of the limit frame, and multiple extrusion rods are rotatably connected to the outside of the crankshaft. A crushing column is rotatably connected to the other end of each extrusion rod, and the crushing column slides in cooperation with the limit frame.

[0009] By adopting the above technical solution, when the electric telescopic rod drives the tilting frame to shift at an angle, the shifting frame drives the limit frame to shift synchronously, so that the internal crushing column can crush the road surface cut by the cutting part under the drive of the crankshaft, making the trench excavation operation at the road surface groove more convenient.

[0010] As an optional solution to the technical solution in this application, the mounting frame includes a wheel plate frame with power supply facilities installed. A support frame is slidably connected to the outside of the wheel plate frame, and two electric lifting columns are fixedly connected to the support frame and the wheel plate frame in a symmetrical structure.

[0011] By adopting the above technical solution, a mounting frame that can be raised and lowered is formed by using a wheel plate frame, a support frame and an electric lifting column. This allows the mounting frame to adjust the cutting depth of the cutting parts, ensuring the flexibility of the cutting parts in cutting applications.

[0012] As an optional solution to the technical solution in this application, a telescopic sleeve is fixedly connected between both ends of the two crossbars.

[0013] By adopting the above technical solution, the telescopic sleeve can protect the outside of the sliding path between the crossbar and the mounting bracket, ensuring the smooth sliding adjustment of the crossbar.

[0014] As an optional solution to the technical solution of this application, the cutting component is externally fitted with an anti-cut sleeve, and a splash guard is hinged to one side of the anti-cut sleeve. A roller is rotatably connected to the outside of the splash guard.

[0015] By adopting the above technical solutions, the cut-resistant sleeve can shield the saw blade of the cutting workpiece, preventing accidental injury to others, while the splash guard can protect against the debris splashed by the saw blade, further ensuring the safety of the cutting workpiece.

[0016] As an optional solution to the technical solution in this application, one end of the flipping frame is rotatably connected to multiple rollers.

[0017] By adopting the above technical solution, the use of rollers can ensure smoother sliding adjustment of the tilting frame along the outside of the crossbar, reducing frictional resistance.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application utilizes an electric telescopic rod to drive the tilting frame to shift angles. The shifting frame causes the limiting frame to shift synchronously, allowing the internal crushing column to crush the road surface cut by the cutting component under the drive of the crankshaft, making the trench excavation operation at the road surface grooving point more convenient.

[0020] 2. This application utilizes a telescopic sleeve to protect the external sliding path of the crossbar and the mounting bracket, ensuring smooth operation of the crossbar's sliding adjustment. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1-6 The adjustable width grooving device for municipal engineering described in this application includes a mounting frame 1 for installing power supply facilities. The mounting frame 1 has two horizontal bars 2 slidably connected in a symmetrical structure. One of the horizontal bars 2 is fixedly connected to the mounting frame 1 by bolts. A cutting piece 3 is fixedly connected to one side of the horizontal bar 2. A flipping frame 4 is slidably connected between the two horizontal bars 2. One end of the flipping frame 4 abuts against the horizontal bar 2 through a fastening handwheel. An electric telescopic rod 5 is fixedly connected between the flipping frame 4 and the horizontal bar 2. A limit frame 6 is fixedly connected to one side of the flipping frame 4. A crankshaft 7 is rotatably connected inside the limit frame 6. One end of the crankshaft 7 passes through the limit frame 6 and is fixedly connected to a drive motor 8. The drive motor 8 is fixedly connected to the side wall of the limit frame 6. Multiple extrusion rods 9 are rotatably connected to the outside of the crankshaft 7. A crushing column 10 is rotatably connected to the other end of the extrusion rod 9. The crushing column 10 is slidably engaged with the limit frame 6.

[0030] The municipal engineering project uses an adjustable width grooving device. When the electric telescopic rod 5 drives the tilting frame 4 to shift at an angle, the tilting frame 4 shifts synchronously with the limit frame 6, so that the internal crushing column 10 can crush the road surface cut by the cutting part 3 under the drive of the crankshaft 7, making the trench excavation operation at the road surface grooving point more convenient.

[0031] Reference Figure 3 and Figure 1 The adjustable width slotting device for municipal engineering described in this application includes a mounting frame 1 with a power supply facility installed on it. A support frame 12 is slidably connected to the outside of the wheel plate frame 11. Two electric lifting columns 13 are fixedly connected to the support frame 12 and the wheel plate frame 11 in a symmetrical structure.

[0032] The municipal engineering uses an adjustable width grooving device, which forms an adjustable mounting frame 1 by using a wheel plate frame 11, a support frame 12 and an electric lifting column 13. This allows the mounting frame 1 to drive the cutting part 3 to adjust the cutting depth, ensuring the flexibility of the cutting part 3 in cutting.

[0033] Reference Figure 4 and Figure 1 In the adjustable width slotting device for municipal engineering described in this application embodiment, telescopic sleeves 21 are fixedly connected between the two ends of the two crossbars 2.

[0034] The municipal engineering project uses an adjustable width slotting device. By utilizing the telescopic sleeve 21, the sliding path of the crossbar 2 and the mounting frame 1 can be protected, ensuring the smooth sliding adjustment of the crossbar 2.

[0035] Reference Figure 5 and Figure 1In the adjustable width grooving device for municipal engineering described in this application embodiment, the cutting part 3 is externally sleeved with an anti-cut sleeve 31, and a splash guard 32 is hinged to one side of the anti-cut sleeve 31. Rollers are rotatably connected to the outside of the splash guard 32.

[0036] The municipal engineering uses an adjustable width grooving device. By using the anti-cut sleeve 31, the saw blade of the cutting part 3 can be shielded to prevent the cutting part 3 from accidentally injuring others, while the splash guard 32 can protect the debris splashed by the saw blade, further ensuring the safety of the cutting part 3.

[0037] Working principle: When it is necessary to adjust the distance between the two cutting pieces 3 and the road surface cutting joint, the operator starts the electric telescopic rod 5 to limit the telescopic adjustment, thereby driving one end of the tilting frame 4 to slide and adjust with the crossbar 2. Since the other end of the tilting frame 4 is connected to the other crossbar 2 through bolts, when the electric telescopic rod 5 drives one end of the tilting frame 4 to move, the distance between the two crossbars 2 is adjusted under the sliding limit of the mounting frame 1, thus changing the cutting distance between the two cutting pieces 3.

[0038] Next, the mounting bracket 1 is raised and lowered to adjust the cutting depth of the cutting piece 3;

[0039] Finally, start the cutting component 3 and drive motor 8 to cut the road surface and drive the crushing column 10 to impact and crush the cut road surface.
