Description

Technical Field

[0001] The invention belongs to the technical field of roughening processing devices, and in particular relates to an integrated device for roughening and high-pressure water cleaning of the hole wall of a prefabricated pier of a bridge. Background Art

[0002] Large-volume concrete precast piers are an important structural form of offshore highway bridge engineering. Figure 1 Large-volume concrete bridge precast piers have multiple holes, called post-cast holes (because concrete needs to be poured into them when connecting to the cap foundation). Post-cast holes are the key parts connecting the precast components to the cap foundation. During assembly and construction, the large-volume concrete bridge precast piers are transported to the site for hoisting. The post-cast holes of the large-volume concrete bridge precast piers are then inserted into the cap foundation, and concrete is poured into the post-cast holes to achieve a stable connection between the precast piers and the cap foundation.

[0003] Roughening the walls of the post-cast holes of the above-mentioned large-volume concrete bridge precast piers is an essential process. By roughening, indentations are formed on the walls of the post-cast holes, thereby enhancing the interface bonding performance with the post-cast concrete.

[0004] At present, when using traditional chiseling machines to roughen the walls of the post-cast holes of the above-mentioned precast bridge piers, a large amount of dust is generated in the holes. Due to the poor ventilation in the holes, the temperature in the holes can be very high in summer. Workers are exposed to dust and high temperatures for a long time, which is not good for their health. In addition, after the chiseling hammer head of the chiseling machine hits the surface of the concrete hole wall, there are still loose but not detached concrete fragments. If these fragments are not removed, the bonding force between the concrete and the roughened surface will be greatly weakened during the subsequent pouring of concrete. Therefore, for the roughening work of the post-cast hole walls of large-volume concrete precast bridge piers, how to efficiently perform the chiseling and fragment removal process and reduce dust and lower the temperature in the hole is a technical problem that needs to be solved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide an integrated device for roughening and high-pressure water cleaning of the wall of a prefabricated pier hole of a bridge, which is used to roughen the concrete surface of the pier hole wall and remove attached debris, reduce dust during construction and lower the temperature inside the hole.

[0006] The present invention is achieved through the following technical solutions: An integrated device for roughening and high-pressure water cleaning of prefabricated bridge pier hole walls, comprising: a device housing, and a roughening device, a guide caster, and a swinging high-pressure water cleaning mechanism integrally mounted on the device housing; The device shell is a rectangular box structure, and the oscillating high-pressure water cleaning mechanism includes a vertical collecting pipe, a liquid inlet pipe, a rotating sleeve, a shaft, a guide rotating cylinder and a motor. A plurality of nozzles are arranged at intervals from top to bottom on the outside of the vertical collecting pipe. The liquid inlet pipe is connected to the middle position of the vertical collecting pipe and is connected thereto. The liquid inlet pipe is arranged horizontally, and a liquid inlet interface is provided on the liquid inlet pipe for connecting to a high-pressure water supply pipeline; the front end of the liquid inlet pipe is connected to the rotating sleeve through a first connecting rod, and the rotating sleeve is installed on the shaft through a bearing, and the shaft is fixedly installed on the device shell, and a second connecting rod is fixedly connected to the side of the rotating sleeve opposite to the first connecting rod, and the end of the second connecting rod is in contact with the wavy guide curve structure at the bottom of the guide rotating cylinder. The guide rotating cylinder is arranged vertically, and its top end is connected to the output shaft of the motor, and the motor is fixedly installed on the inner wall of the device shell; a torsion spring is also provided between the shaft and the rotating sleeve to keep the second connecting rod on the rotating sleeve in contact with the wavy guide curve structure at the bottom of the guide rotating cylinder.

[0007] In the above technical solution, the chiseling tool is fixedly mounted inside the device housing via a mounting base.

[0008] In the above technical solution, there are three chiseling tools arranged in a triangle.

[0009] In the above technical solution, each chiseling device has a plurality of chiseling hammer heads arranged vertically, and a through hole is provided on the back plate of the device housing, through which the chiseling hammer heads extend outward from the device housing.

[0010] In the above technical solution, an inlet hole is provided on the device housing for the high-pressure water supply pipeline to enter the interior of the device housing and connect with the liquid inlet interface of the liquid inlet pipe.

[0011] In the above technical solution, a vertical long hole is provided on the back plate of the device housing for the vertical collecting pipe to pass through the device housing.

[0012] In the above technical solution, a connecting frame is provided on the front panel of the device casing, which is used to install the device casing on a robotic arm or other mobile mechanism to drive the device casing (that is, drive the entire integrated chiseling and high-pressure water cleaning device) to move and perform operations on the concrete surface of the pier hole wall.

[0013] In the above technical solution, there are four guide casters, which are fixedly installed at the four corners of the device housing. The guide casters are arranged on the side of the device housing facing the concrete surface of the pier hole wall to be constructed. The guide casters are used to contact the concrete surface of the pier hole wall to be constructed to form a rolling support effect.

[0014] The advantages and beneficial effects of the present invention are: The present invention is an integrated device for roughening and high-pressure water cleaning of prefabricated bridge pier holes. A roughening device, a guide caster, and a swinging high-pressure water cleaning mechanism are integrated in the device housing. The guide caster is arranged on the side of the device housing facing the concrete surface of the pier hole wall to be constructed. The guide caster is used to contact the concrete surface of the pier hole wall to be constructed to form a rolling support effect, so that the integrated device for roughening and high-pressure water cleaning can maintain a certain construction distance from the concrete surface of the pier hole wall to be constructed, thereby ensuring operational stability. The roughening device and the swinging high-pressure water cleaning mechanism can simultaneously perform roughening and high-pressure water cleaning operations on the prefabricated bridge pier hole wall. That is, during the process of moving the integrated device for roughening and high-pressure water cleaning, the roughening device is first used for roughening, and then the swinging high-pressure water cleaning mechanism performs high-pressure water cleaning on the construction surface after the roughening device is hammered, thereby removing concrete debris that has been loosened but not separated from the construction surface and reducing dust during the construction process. In addition, since water is sprayed during roughening, the temperature inside the prefabricated bridge pier hole is also reduced.

[0015] In addition, the present invention is capable of swinging and spraying water on the concrete surface of the prefabricated pier hole wall of the bridge through the designed swinging high-pressure water cleaning mechanism. This swinging water spraying can increase the spraying operation area of the concrete surface of the pier hole wall and make the spraying angle change in real time, which helps to knock down the loose debris on the concrete surface of the pier hole wall.

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention are further described below with reference to specific embodiments.

[0023] An integrated device for roughening and high-pressure water cleaning of prefabricated bridge pier holes, see attached Figure 2 -Attached Figure 5 , including: a device housing 1 and a chiseling device 2, a guide caster 3 and a swinging high-pressure water cleaning mechanism 4 integratedly installed on the device housing 1.

[0024] The device housing 1 is a rectangular box structure, and the chiseling tool 2 is fixedly installed inside the device housing 1 through a mounting base 5. There are three chiseling tools 2, which are arranged in a triangle. Each chiseling tool 2 has three vertically arranged chiseling hammer heads. A through hole 103 is provided on the back plate of the device housing 1 (that is, the plate of the device housing 1 facing the concrete surface of the pier hole wall to be constructed). The chiseling hammer head extends outward from the device housing 1 through the through hole 103, and the concrete surface of the pier hole wall is chiseled by the chiseling hammer head.

[0025] The swing high-pressure water cleaning mechanism 4 includes a vertical collecting pipe 401, a liquid inlet pipe 402, a rotating sleeve 403, a shaft 404, a guide rotating cylinder 405 and a motor 406. A plurality of nozzles 4011 are arranged at intervals from top to bottom on the outside of the vertical collecting pipe 401. The liquid inlet pipe 402 is connected to the middle position of the vertical collecting pipe 401 and is connected thereto. The liquid inlet pipe 402 is arranged horizontally and is provided with a liquid inlet interface 4021 for connecting to a high-pressure water supply pipeline. The front end of the liquid inlet pipe 402 is connected to the rotating sleeve 403 through a first connecting rod 407. The rotating sleeve 403 is mounted on the shaft 404 through a bearing. The shaft 404 is longitudinally fixedly mounted on the device housing. 1, a second connecting rod 408 is fixedly connected to the side of the rotating sleeve 403 opposite to the first connecting rod 407, and the end of the second connecting rod 408 contacts the bottom of the guide rotating cylinder 405. The guide rotating cylinder 405 is vertically arranged, and its top end is connected to the output shaft of the motor 406. The motor 406 is fixedly mounted on the inner wall of the device housing 1. The bottom of the guide rotating cylinder 405 is a wavy guide curve structure 4051. Furthermore, a torsion spring is provided between the shaft 404 and the rotating sleeve 403 to keep the second connecting rod 408 on the rotating sleeve 403 in contact with the wavy guide curve structure 4051 at the bottom of the guide rotating cylinder 405. During operation, the motor 406 drives the guide rotating cylinder 405 to rotate. Since the bottom of the guide rotating cylinder is a wavy guide curve structure, the guide rotating cylinder 405 will drive the second connecting rod 408 to move up and down when it rotates, and then the liquid inlet pipe 402 and the vertical collecting pipe 401 are swung up and down with the shaft 404 as the rotation center, so as to realize the up and down swinging and high-pressure water spraying on the concrete surface of the pier hole wall; further speaking, the swinging high-pressure water cleaning mechanism 4 is located on one side of the three chiseling devices 2. When working, the chiseling and high-pressure water cleaning integration of the present invention is driven by the mechanical arm. The device moves laterally in the direction opposite to the swinging high-pressure water cleaning mechanism 4. During the movement, the chiseling device 2 and the swinging high-pressure water cleaning mechanism 4 are turned on at the same time, thereby realizing the chiseling and high-pressure water cleaning operations on the concrete surface of the pier hole wall. That is, during the movement, the chiseling device 2 is first used for chiseling, and then the swinging high-pressure water cleaning mechanism 4 performs high-pressure water cleaning on the construction surface after the chiseling of the chiseling device 2, thereby removing the concrete fragments that have been loosened but not separated from the construction surface and reducing the dust during the construction process, thereby ensuring the pouring effect of the subsequent concrete pouring.

[0026] Furthermore, an inlet hole 101 is provided on the device housing 1 for the high-pressure water supply pipeline to enter the interior of the device housing 1 and be connected to the liquid inlet interface of the liquid inlet pipe 402; a vertical long hole 104 is provided on the back plate of the device housing 1 (that is, the plate of the device housing 1 facing the concrete surface to be constructed) for the vertical collecting pipe 401 to pass through the device housing 1.

[0027] Furthermore, a connecting frame 102 is provided on the front panel of the device housing 1, which is used to install the device housing 1 on a robotic arm or other mobile mechanism to drive the device housing 1 (that is, drive the entire integrated chiseling and high-pressure water cleaning device) to move and perform operations on the concrete surface of the pier hole wall.

[0028] There are four guide casters 3, which are fixedly installed at the four corners of the device housing 1. The guide casters 3 are arranged on the side of the device housing 1 facing the concrete surface of the pier hole wall to be constructed. The guide casters 3 are used to contact the concrete surface of the pier hole wall to be constructed to form a rolling support effect, so that the integrated chiseling and high-pressure water cleaning device can maintain a certain construction distance from the concrete surface of the pier hole wall to be constructed, ensure the stability of the operation, and play a rolling guide role when moving.

[0029] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0030] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0031] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other skilled in the art without expending creative labor falls within the scope of protection of the present invention.
