[0033] A road cutting machine for electric power foundation construction, like Figures 1-3As shown, including the frame 1, cutting parts and water tank, frame 1 below rotatably provided with lifting member 2, lifting member 2 on the rotatably provided with the roller, wherein the working principle of the above-mentioned parts has been described in detail in the Chinese patent with publication number CN222008582U, and here will not be described too much, wherein the frame 1 is provided with adjusting device for adjusting the lifting angle of lifting member 2, the whole device includes rotating disc 3 rotatably provided on the frame 1, transmission rope 4 connected with rotating disc 3 and lifting member 2 at both ends respectively, foot pedal mechanism rotatably provided on the frame 1, wherein the foot pedal mechanism is in transmission connection with the rotating disc 3, so as to drive the rotating disc 3 to rotate through the foot pedal mechanism to wind the transmission rope 4, so that the lifting member 2 forms the lifting effect, at the same time, the adjusting device further comprises ratchet assembly fixedly arranged between the rotating disc 3 and the frame 1, the reverse rotation of the rotating disc 3 is limited through the ratchet assembly, the stability of winding the transmission rope 4 is ensured, wherein the ratchet assembly is further connected with unlocking assembly, one end of the unlocking assembly extends to the handle of the frame 1, so that when it is needed to lower the lifting angle, the limiting effect of the ratchet assembly is released through the unlocking assembly, the reverse rotation of the rotating disc 3 can be realized, so as to realize the effect of releasing the transmission rope 4.

[0034] As shown, the outer wall of the rotating disc 3 is provided with accommodating groove, which is used for winding the transmission rope 4, and the subsequent winding of the transmission rope 4 is ensured through the accommodating groove, so as to avoid the knotting of the transmission rope 4 affecting the use.

[0035] As shown, Figures 2-3 The foot pedal mechanism includes transmission part 5 rotatably provided on the frame 1 and pedal 6 rotatably provided on the frame 1, the pedal 6 is symmetrically arranged along the rotation shaft thereof, so that after the user steps on the pedal 6, the pedal 6 is reciprocally rotated through the alternating force of the forefoot and the heel, and the effect of driving the pedal 6 to reciprocally rotate is realized.

[0036] The transmission rod 7 is in transmission connection between the pedal 6 and the transmission part 5, so that when the user reciprocally steps on the pedal 6, the pedal 6 provides the rotating power to the transmission part 5 through the transmission rod 7, and the bending area is arranged at the connection position of the transmission part 5 and the transmission rod 7, so as to make the connection position of the transmission part 5 and the transmission rod 7 deviate from the axis of the rotating shaft of the rotating disc 3, so that the connection position makes the circular motion with the center of the rotating shaft of the rotating disc 3, and the effect of driving the rotating disc 3 to rotate is realized.

[0037] As shown in the figure Figure 3 The ratchet assembly includes ratchet ring 8 fixedly arranged on the rotating disc 3 and pawl member 9 rotatably arranged on the frame 1, the spring 12 is arranged between the frame 1 and the pawl member 9, which is used for pushing the pawl member 9 to abut against the ratchet ring 8, so that the one-way rotation of the rotating disc 3 is realized through the abutment between the pawl member 9 and the ratchet ring 8.

[0038] As Figures 1-2As shown, the unlocking assembly includes a pull rope 10 for pulling the pawl 9 to rotate away from the ratchet ring 8, a press handle 11 rotatably arranged at the handle, and the pull rope 10 is connected to the pawl 9 and the press handle 11 at both ends, so that the pawl 9 can be pulled away from the ratchet ring 8 by applying pressure to the press handle 11.

[0039] As shown, Figure 1 The frame 1 is provided with two handles, and the press handle 11 is arranged on each handle, so that the user needs to hold the handle with both hands and apply pressure at the same time to realize the down-regulation operation, thereby improving the operation safety. Because the user needs to hold the handle with both hands, it can ensure that external force can be applied in time during down-regulation to limit the down-regulation speed and avoid loss of control.

[0040] As shown, Figures 1-2 The frame 1 is provided with two handles, and the press handle 11 is arranged on each handle, so that the user needs to hold the handle with both hands and apply pressure at the same time to realize the down-regulation operation, thereby improving the operation safety. Because the user needs to hold the handle with both hands, it can ensure that external force can be applied in time during down-regulation to limit the down-regulation speed and avoid loss of control.

[0041] Working principle: According to the cutting depth, the user holds the handle of the frame 1 with both hands, then steps on the pedal 6 with one foot, and then repeatedly steps on the pedal 6, so that the pedal 6 swings back and forth. The pedal 6 drives the transmission part 5 to rotate through the transmission rod 7, so that the transmission part 5 and the rotating disc 3 rotate together, the rotating disc 3 realizes the effect of winding the transmission rope 4, and the lifting piece 2 rotates to form the lifting effect. When the rotating disc 3 rotates, the ratchet ring 8 also rotates, and the pawl 9 limits the back rotation of the ratchet ring 8, thereby ensuring the winding of the rotating disc 3.

[0042] When the user down-regulates the height, the user needs to hold the handle of the frame 1 with both hands, then hold the press handle 11, and at the same time, apply pressure to the two press handles 11, so that the pull rope 10 pulls the pawl 9 to rotate away from the ratchet ring 8, thereby releasing the fixing of the ratchet ring 8 and the rotating disc 3, so that the rotating disc 3 can realize back rotation. When the rotating disc 3 back rotates, the rotating disc 3 can drive the pedal 6 to rotate through the transmission part 5 and the transmission rod 7, and the user can step on the pedal 6 with one foot to control the rotation frequency of the pedal 6, thereby controlling the back rotation speed of the rotating disc 3. At the same time, the user can also apply pressure to the handle of the frame 1 with both hands to limit the down-regulation speed, thereby avoiding the situation that the speed is too fast during back rotation, which causes bumping.

[0043] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
