Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and in particular relates to a device for cutting concrete on slopes. Background Technology

[0002] Currently, many C30 cast-in-place plain concrete slab slope protection structures exist in the construction process of the river embankment section. In order to adapt to temperature changes, shrinkage and creep and uneven settlement of the foundation, and to prevent cracking and damage to the slope protection structure, a transverse joint is set at intervals along the direction of water flow on the sloping slope surface, and a longitudinal joint is set at intervals along the direction of the canal slope from the bottom of the canal; an expansion joint is set at intervals along the direction of water flow, and the expansion joint is a continuous joint.

[0003] Traditional concrete slope cutting methods are limited by steep slopes (especially those >30°) and complex curved surfaces. Conventional cutting equipment is prone to slippage and deviation, and manual operation of grinding machines is difficult and dangerous, resulting in poor cut straightness, uneven depth, low efficiency, and difficulty in ensuring accuracy. This not only affects the durability and appearance of the structure, but also leads to high maintenance costs in the later stages. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a device for cutting sloping concrete, which addresses the shortcomings of the prior art. By setting a hydraulic leveling base at the bottom of the track, the height of the track can be adjusted according to the slope angle, so that the guide rail of the cutting machine is always kept horizontal or on the set working reference surface, providing a stable platform for the cutting machine. Combined with the negative pressure adsorption force generated by the adsorption plate at the bottom of the track, the overall stability of the equipment is further enhanced.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for cutting concrete on a slope, including a cutting machine guide rail set on the slope, a cutting machine set on the cutting machine guide rail and running along the extension direction of the cutting machine guide rail, and an adjustment mechanism set on the cutting machine guide rail and used to adjust the position of the cutting machine guide rail. The cutting machine guide rail includes two rails symmetrically arranged on the slope and multiple connecting rods arranged between the two rails. The multiple connecting rods are evenly distributed along the extension direction of the rails and are integrally formed with the rails. The adjustment mechanism includes an adsorption plate and a hydraulic leveling base, both of which are disposed at the bottom of the track. There are multiple adsorption plates, which are evenly distributed at the bottom of the track. Multiple rubber anti-slip pads are also disposed between two adjacent adsorption plates, and the multiple rubber anti-slip pads are evenly distributed along the extension direction of the track.

[0006] Furthermore, a distance measuring sensor is also provided at the bottom of the track, and the number of the distance measuring sensors is equal to the number of the hydraulic leveling chassis and corresponds one-to-one.

[0007] Furthermore, the cutting machine is equipped with an infrared transmitter, and an infrared receiver that cooperates with the infrared transmitter is provided at the end of the slitting machine guide rail away from the cutting machine.

[0008] Furthermore, the adsorption plate is controlled by a controller, and a limit switch is provided at the bottom of the adsorption plate. The signal output terminal of the limit switch, the signal output terminal of the ranging sensor, the signal output terminal of the infrared transmitter, and the signal output terminal of the infrared receiver are all connected to the signal input terminal of the controller.

[0009] Furthermore, the bottom of the cutting machine is equipped with rollers that cooperate with the track.

[0010] The beneficial effect of this utility model is that by setting a hydraulic leveling base at the bottom of the track, the height of the track can be adjusted according to the slope angle, so that the guide rail of the cutting machine is always kept horizontal or on the set working reference surface, providing a stable platform for the cutting machine; combined with the negative pressure adsorption force generated by the adsorption plate at the bottom of the track, the overall stability of the equipment is further enhanced.

Detailed Implementation

[0015] like Figure 1 and Figure 2 As shown, this utility model includes a cutting machine guide rail 1 set on a slope, a cutting machine 2 set on the cutting machine guide rail 1 and running along the extension direction of the cutting machine guide rail 1, and an adjustment mechanism set on the cutting machine guide rail 1 for adjusting the position of the cutting machine guide rail 1. The cutting machine guide rail 1 includes two rails 3 symmetrically arranged on the slope and multiple connecting rods 4 arranged between the two rails 3. The multiple connecting rods 4 are evenly distributed along the extension direction of the rails 3, and the multiple connecting rods 4 and the rails 3 are integrally formed. The adjustment mechanism includes an adsorption plate 5 and a hydraulic leveling base plate 11, both of which are disposed at the bottom of the track 3. There are multiple adsorption plates 5, which are evenly distributed at the bottom of the track 3. Multiple rubber anti-slip pads 6 are also disposed between two adjacent adsorption plates 5, which are evenly distributed along the extension direction of the track 3.

[0016] In actual use, by setting a hydraulic leveling base 11 at the bottom of the track 3, the height of the track 3 can be adjusted according to the slope angle, so that the cutting machine guide rail 1 is always kept horizontal or on the set working reference surface, providing a stable platform for the cutting machine 2; combined with the negative pressure adsorption force generated by the adsorption plate 5 at the bottom of the track 3, the overall stability of the equipment is further enhanced.

[0017] It should be noted that the suction cup 5 is fixed to the bottom of the track 3 by a suction cup fixing rod, and the suction cup 5 moves up and down under the action of the suction cup fixing rod.

[0018] In this embodiment, a distance sensor 9 is also provided at the bottom of the track 3. The number of distance sensors 9 is equal to the number of hydraulic leveling chassis 11 and they correspond one-to-one.

[0019] In actual use, the distance sensor 9 can be used to determine the difference between the track 3 and the horizontal or set working reference plane. The height of the track 3 can be adjusted by the hydraulic leveling chassis 11 to keep the cutting machine guide rail 1 always on the horizontal or set working reference plane.

[0020] In this embodiment, an infrared transmitter 10 is provided on the cutting machine 2, and an infrared receiver 12 that cooperates with the infrared transmitter 10 is provided at the end of the cutting machine guide rail 1 away from the cutting machine 2.

[0021] In actual use, the infrared transmitter 10 and the infrared receiver 12 provide guidance for this device to prevent deviation during the cutting process. Before use, the positions of the infrared transmitter 10 and the infrared receiver 12 are set according to the direction of the cut. During the cutting process, the infrared transmitter 10 emits infrared rays. When the infrared receiver 12, located at the end of the cutting machine guide rail 1 away from the cutting machine 2, receives a signal, it indicates that the traveling direction of the cutting machine guide rail 1 and the cutting machine 2 has not deviated, and cutting can continue. If no signal is received, it indicates that the traveling direction of the cutting machine guide rail 1 and the cutting machine 2 has deviated, and the controller 7 activates the alarm and makes timely adjustments. The infrared receiver 12 is positioned in the middle of the two tracks 3. An electrical control box is installed on the cutting machine 2, and a circuit board is installed inside the electrical control box. The circuit board integrates the controller 7 and an alarm connected to the controller 7.

[0022] In this embodiment, the adsorption disk 5 is controlled by the controller 7. A limit switch 8 is provided at the bottom of the adsorption disk 5. The signal output terminal of the limit switch 8, the signal output terminal of the ranging sensor 9, the signal output terminal of the infrared transmitter 10, and the signal output terminal of the infrared receiver 12 are all connected to the signal input terminal of the controller 7.

[0023] In actual use, the controller 7 drives the adsorption plate 5 to descend. When the limit switch 8 contacts the slope, the controller 7 controls the adsorption plate 5 to stop descending. The suction force of the adsorption plate 5 is generated by the gas flowing into the vacuum generator, which adsorbs the slope.

[0024] In this embodiment, the bottom of the cutting machine 2 is provided with rollers that cooperate with the track 3.

[0025] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
