[0002] During the laying of municipal pipelines or cables, it is usually necessary to trench the ground or walls according to the layout of drainage pipes, gas pipes, electrical wires, etc., in the drawings before laying the pipelines or cables. Currently, there are many trenching devices on the market for municipal construction, such as a concrete ground trenching device for municipal construction disclosed in Chinese patent CN216973065U, a municipal road surface trenching device disclosed in Chinese patent CN222822048U, and a municipal construction trenching machine disclosed in Chinese patent CN221167397U. However, these trenching devices are only suitable for trenching the ground and are difficult to apply to trenching the walls. Wall trenching construction mostly involves first marking lines according to the drawings, and then using a handheld trenching machine to trench along the marked lines. Maintaining the trench vertically or horizontally requires a high level of skill from the worker.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0022] like Figure 1-4 As shown, a grooving device for municipal construction includes a guide frame 2 and a grooving machine 1. The guide frame 2 includes several straight supports. An adjustment seat is provided at the front end of the grooving machine 1, with a through hole 6 at the center of the adjustment seat corresponding to the grooving drill bit 10. A stroke extension hole 14 is provided in the middle of the support bracket corresponding to the grooving drill bit 10 of the grooving machine 1. A hanging mechanism 13 is provided at one end of the straight supports, a first positioning mechanism 15 is provided at the other end, and second positioning mechanisms 16 are provided on both sides of the straight supports. The first positioning mechanism 15 is detachably connected to the ground or the second positioning mechanism 16. Specifically, the grooving machine can be a common handheld grooving device in the prior art, and the hanging mechanism can be a common hanging ring and / or hook. When the straight supports are set vertically, the lower end is connected to the ground by bolts, and hanging rings and / or hooks are provided on the wall to facilitate the upper end of the straight supports for hanging, thereby improving the stability of the structure.

[0023] This municipal construction grooving device combines a conventional handheld grooving machine with a guide frame for vertical wall grooving. It boasts a simple structure, reasonable design, and low modification costs. In practical use, lines are first drawn according to the drawings, then the guide frame is installed. The handheld grooving machine is then used to groove along the guide frame. For example, for vertical grooving, a straight support is placed vertically against the wall, perpendicular to the ground. The first positioning mechanism is fixed to the ground with positioning bolts. The vertical grooving line is aligned with the center axis of the long-stroke hole. The handheld grooving machine is then moved along the long-stroke hole to perform the grooving operation. For horizontal grooving, a straight support is first placed vertically against the wall, perpendicular to the ground. The first positioning mechanism is fixed to the ground with positioning bolts. Then, another straight support is placed horizontally against the wall, parallel to the ground. The first positioning mechanism of this horizontal support is fixedly connected to the second positioning mechanism of the vertically placed straight support. The horizontal grooving line is aligned with the center axis of the long-stroke hole of this horizontal support. The handheld grooving machine is then used. During application, multiple guide frames can be installed, and multiple people can use handheld grooving machines to perform grooving separately; or two workers can work simultaneously, each using a grooving machine to perform horizontal and vertical grooving.

[0024] In one embodiment, the first positioning mechanism 15 includes an inverted U-shaped groove, and a first positioning hole is provided on the horizontal top plate on the upper side of the inverted U-shaped groove; the second positioning mechanism 16 includes a straight protrusion that mates with the inverted U-shaped groove and a second positioning hole provided on the straight protrusion, wherein the first positioning hole is detachably connected to the ground or the second positioning hole. Specifically, the first positioning hole and the second positioning hole can be threaded holes to facilitate bolt fixing connection.

[0025] In one embodiment, the grooving machine 1 mainly includes a housing 8, a drill bit mounting base 9 disposed on the housing 8, a grooving drill bit 10 connected to the drill bit mounting base 9, a drill bit drive mechanism 11 disposed inside the housing 8, and a power cord 12, which are common grooving structures in the art. During use, the power cord connects to a power source to supply power to the drill bit drive mechanism, which mainly includes a motor, transmission gears, and other mechanisms for transmission connection with the grooving drill bit.

[0026] In one embodiment, the adjusting seat includes a fixed sleeve 3 and a movable sleeve 4, which form a telescopic structure. The fixed sleeve 3 is fixed to the drill bit mounting seat 9 and coaxial with the grooving drill bit 10. The outer diameter of the movable sleeve 4 is larger than the width of the stroke length hole 14, and a through hole 6 is provided at the center of the movable sleeve 4, through which the grooving drill bit 10 passes. During the grooving process, the front end of the adjusting seat abuts against the guide frame.

[0027] In one embodiment, one end of the movable sleeve 4 extends into the interior of the fixed sleeve 3. The outer wall of the movable sleeve 4 is provided with external threads, and the inner wall of the fixed sleeve 3 is provided with internal threads. The movable sleeve 4 and the fixed sleeve 3 are threadedly connected. Before use, the spiral connection depth of the movable sleeve can be adjusted according to the required groove depth. The smaller the spiral connection depth of the movable sleeve, the smaller the groove depth.

[0028] In one embodiment, the end of the movable sleeve 4 that extends into the fixed sleeve 3 is provided with an abutment plate, which is connected to the drill bit mounting seat 9 by a spring to improve the stability of the structure.

[0029] In one embodiment, a sealing plate 7 is provided at one end of the movable sleeve 4 outside the fixed sleeve 3, and a through hole 6 is opened in the center of the sealing plate 7; a set of universal balls 5 arranged in a straight line are provided on both sides of the sealing plate 7; guide grooves 17 are provided on both sides of the straight bracket corresponding to the long stroke hole 14, the guide grooves 17 are parallel to the long stroke hole 14, and the universal balls 5 slide with the guide grooves 17 to improve the stability of the structure and avoid displacement during the grooving process.

[0030] In one embodiment, the outer wall of the movable sleeve 4 is provided with scale markings to facilitate operators in adjusting the groove depth.

[0031] The above embodiments can be combined with each other.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
