Description

Technical Field

[0001] This utility model belongs to the technical field of road construction equipment, specifically relating to a highway pavement crushing device. Background Technology

[0002] As a core infrastructure of modern transportation, highways need to be reconstructed, expanded, or upgraded with the development of the social economy and the increase in traffic volume. In this process, it is necessary to break up and demolish the original concrete or asphalt concrete pavement.

[0003] The methods for breaking up concrete pavements usually rely on the principle of impact crushing. The equipment used mainly includes pneumatic picks, hydraulic breakers, etc. These devices apply high-frequency, high-intensity mechanical impact force to the pavement through chisels or hammers, thereby breaking the pavement.

[0004] The problem is that high-frequency, high-intensity mechanical impacts can generate severe vibrations that can propagate through the ground and potentially damage underground pipelines, building foundations, and precision instruments near the construction area. High-frequency impacts can also cause noise pollution, affecting the work and lives of residents, hospitals, schools, and other noise-sensitive areas along the road. Utility Model Content

[0005] To address the problems encountered in the aforementioned background technology, this application proposes a road surface demolition device based on the static expansion and crushing principle.

Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0021] This embodiment provides a road surface breaking device, see reference. Figures 1-5 As shown, the system includes two parallel first guide rails 1 and two parallel second guide rails 2. The first guide rails 1 are positioned above the second guide rails 2, and the second guide rails 2 support the first guide rails 1. A horizontal rail 3 is provided between the two first guide rails 1. A support plate 4 is provided at the upper end of the first guide rail 1, and the support plate 4 is slidably connected to the first guide rail 1. The two ends of the horizontal rail 3 are respectively connected to the support plates 4 on the two first guide rails 1. A first motor 11 and a second motor 12 are respectively provided at both ends of one of the first guide rails 1, and the output ends of the first motor 11 and the second motor 12 are connected to a first spool 111 and a second spool 121. The first spool 111 and the second spool 121 are connected to the two sides of the support plate 4 by ropes. A moving part 5 is provided on the horizontal rail 3, and a mounting platform 51 is provided on the moving part 5. The mounting platform 51 is used to fix and install the drill bit assembly and the pouring pipe.

[0022] In the above embodiment, the second guide rail 2 is disposed below the first guide rail 1 to support the first guide rail 1. The support plate 4 is slidably connected to the first guide rail 1, and both ends of the horizontal rail 3 are respectively connected to the support plates 4 on the two first guide rails 1, so that the horizontal rail 3 can move along the setting direction of the first guide rail 1. Further, the first spool 111 and the second spool 121 are connected to the two sides of the support plate 4 by ropes, such as... Figure 2 For example, the first motor 11 and the second motor 12 are controlled to operate synchronously. When the first motor 11 drives the first spool 111 to rotate for rope winding, the second motor 12 drives the second spool 121 to rotate for rope unwinding, causing the pallet 4 to move the horizontal rail 3 to the right along the first guide rail 1. Similarly, when the first motor 11 drives the first spool 111 to rotate for rope unwinding, the second motor 12 drives the second spool 121 to rotate for rope winding, causing the pallet 4 to move the horizontal rail 3 to the left along the first guide rail 1. The horizontal rail 3 is provided with a moving part 5, and the moving part 5 is provided with a mounting platform 51. The mounting platform 51 is used for... The device uses a fixed installation of a drill bit assembly and a pouring pipe. The drill bit assembly is used to drill holes into the road surface, and the pouring pipe is used to inject HSCA into the drill holes. HSCA is an existing product that is mixed with water to form a slurry and injected into the drill holes of the concrete. Within 4 to 24 hours, its volume expands by 1.5 to 2 times. When the expansion stress exceeds the tensile strength of the road surface, the road surface cracks and breaks. That is, the drill bit assembly of this device drills holes in the road surface, and then the expansion and breaking agent is injected into the holes through the pouring pipe to achieve the breaking of the road surface. In other words, chemical static expansion force is used to replace mechanical impact force. There is no vibration generated during the construction process, which reduces noise pollution.

[0023] In one embodiment of this application, see reference Figure 2 As shown, the bottom end of the tray 4 is provided with a first pulley 41, which is respectively clamped on both sides of the first guide rail 1.

[0024] In the above embodiment, each tray 4 is provided with two first pulleys 41 at its bottom end. The two first pulleys 41 are in rolling contact with the two sides of the first guide rail 1 respectively. The first pulleys 41 are provided at the lower part of both sides of the tray 4 to support the two sides of the tray 4, so as to improve the stability of the tray 4 sliding on the first guide rail 1.

[0025] In one embodiment of this application, see [reference] Figure 2 As shown, a first push block 21 is provided at the end of the second guide rail 2, and a mounting plate 22 that cooperates with the first push block 21 is provided on the side of the second guide rail 2.

[0026] In the above embodiment, the first push block 21 cooperates with the mounting plate 22. That is, the first push block 21 and the mounting plate 22, which are set on the second guide rail 2, respectively clamp the ends of the first guide rail 1 on both sides of the end of the first guide rail 1, so as to clamp and fix the two ends of the first guide rail 1 on the second guide rail 2, which is beneficial to improve the stability of the connection and installation of the first guide rail 1 and the second guide rail 2.

[0027] In one embodiment of this application, see [reference] Figure 4 As shown, the pallet 4 is provided with a clamping block 42, which is used to clamp and fix the end of the horizontal rail 3.

[0028] In the above embodiment, the pallet 4 is provided with clamping blocks 42. The two clamping blocks 42 are respectively provided on both sides of the end of the horizontal rail 3 to clamp the end of the horizontal rail 3 and form a rigid connection, so as to improve the stability of the connection and installation of the pallet 4 and the horizontal rail 3, and prevent the drill bit and pouring pipe carried on the mounting platform 51 from swinging or sinking when the motor-driven moving part 5 walks on the horizontal rail 3.

[0029] In one embodiment of this application, see [reference] Figure 1 As shown, the moving part 5 includes a moving plate 52. A plurality of second pulleys 521 are mounted on one end face of the moving plate 52. The plurality of second pulleys 521 roll in contact with the upper and lower end faces of the horizontal rail 3 in the grooves on the upper and lower end faces of the horizontal rail 3, respectively. An electric telescopic rod 522 is provided on the moving plate 52. The telescopic end of the electric telescopic rod 522 is connected to the mounting platform 51 through a connecting block 523. The second pulleys 521 are drivenly connected to the output end of the third motor 5211 on the moving plate 52.

[0030] In the above embodiment, the third motor 5211 drives the second pulley 521 to rotate on the horizontal rail 3, thereby driving the moving plate 52 to move along the setting direction of the horizontal rail 3. The position of the mounting platform 51, i.e. the drill bit assembly and the pouring pipe, is adjusted by controlling the extension and retraction of the electric telescopic rod 522.

[0031] In one embodiment of this application, see [reference] Figure 3As shown, a protective frame 1211 is provided on the outside of the first spool 111 and the second spool 121.

[0032] In the above embodiment, the protective frame 1211 is used to protect the spool, prevent the spool from shifting after being hit, and prevent the spool from jamming, so as to reduce the failure rate of the equipment at the construction site.

[0033] In one embodiment of this application, a cover is provided on the outside of the device.

[0034] In the above embodiments, the cover is made of spliced ​​plates and has an internal cavity. It can be placed on the outside of the device during drilling to reduce the noise generated by the drill bit from spreading outward and to prevent the expansion agent slurry from "punching holes", that is, the expansion agent is sprayed outward from the drill hole.

[0035] In actual use, the two second guide rails 2 are laid parallel to each other on both sides of the work area of ​​the road surface to be broken and leveled and fixed. The two first guide rails 1 are mounted on the second guide rails 2 by brackets to form a running frame. The first push block 21, for example, can be a clamp to fasten the two ends of the first guide rail 1 to the mounting plate 22 on the side of the second guide rail 2. The support plate 4 with the first pulley 41 is mounted on the first guide rail 1. The end of the horizontal rail 3 is rigidly connected to the support plates 4 on both sides by the clamp 42 (such as with locking bolt buckles). The moving plate 52 is embedded into the groove of the horizontal rail 3 by a set of second pulleys 521. The mounting platform 51 is connected to the moving plate 52 by an electric telescopic rod 522. The drill bit assembly and pouring pipe are pre-clamped on the mounting platform 51. The pouring pipe is connected to the mixing and grouting tank. The first motor 11 and the second motor 12 are started, and the support plate 4 and the horizontal rail 3 are moved longitudinally by the rope. The third motor 5211 is started to drive the moving part 5 to move laterally, positioning the drill bit to the first hole position. The electric telescopic rod 522 is controlled to press down at a uniform speed to complete the drilling. Multiple holes are drilled in sequence on the road surface. After the road surface drilling is completed, the mixed HSCA slurry is pumped through the pipeline to the pouring pipe on the mounting platform 51 and injected into the drill hole. The slurry expands in the drill hole for about 6-8 hours, and cracks begin to appear on the road surface. After 24 hours, the cracks have fully developed and formed appropriately sized fragments, which can be removed by an excavator to protect the surrounding buildings from vibration.
