Description

Technical Field

[0001] The invention belongs to the technical field of construction cleaning, and in particular relates to a construction process of roughening and cleaning equipment based on cylindrical bridge piers. Background Art

[0002] At present, roughening technology is widely used in highway bridge deck paving, tunnel wall paving, dams, canals, power plants, airports, water, underwater operations, subways, railways, steel mill slag removal and other fields, but mainly on land; columnar piers refer to piers whose piers are composed of one or several columns. After long-term use, the underwater or near-underwater parts of the piers are often contaminated with dirt and then corroded to cause corresponding surface structural diseases. If they are not cleaned, they will pose a threat to the quality of the building and the safety of personnel; in addition, with the development of social economy, the number of bridges has gradually increased, and the number of existing columnar piers has also gradually increased, and the pressure on the construction of columnar piers and their maintenance and cleaning work has gradually increased. In addition, the urbanization process has also led to the saturation of columnar piers, and related industries have also turned to the maintenance and care of bridges. Therefore, the rapid maintenance and care industry of piers is full of potential, and the roughening of piers as a pre-maintenance operation urgently needs technical upgrades.

[0003] Most of the traditional bridge pier roughening processes use manual labor, which has the problems of high cost, low efficiency, poor construction effect, etc., and there are corresponding hidden dangers in construction safety; other mechanized construction such as pneumatic drill roughening has problems such as uneven roughening depth and difficult to control the roughening quality; electric hammer roughening is prone to safety accidents, and the equipment may be damaged or aged, and may leak electricity, making it unsuitable for underwater operations; large-scale special roughening machines are difficult to launch into the water and are not suitable for curved surface operations.

[0004] Based on this, the present invention provides a construction process of roughening and cleaning equipment based on cylindrical piers to solve the above problems. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a construction process for roughening and cleaning equipment based on cylindrical bridge piers to solve the problems in the prior art.

[0006] One embodiment of the present invention provides a construction process of a chiseling and cleaning device based on a cylindrical bridge pier, wherein the chiseling and cleaning device comprises a suspension support mechanism, a track support mechanism and a chiseling and cleaning mechanism, and the construction process comprises the following steps:

[0007] Installation of the suspension support mechanism: install and fix the suspension support mechanism above the surface of the cylindrical bridge pier to be roughened;

[0008] Track support mechanism installation: connect the track support mechanism with the suspension support mechanism, and install the winch on the track support mechanism;

[0009] Installation of the roughening and cleaning mechanism: Use the winch on the track support mechanism to hook the roughening and cleaning mechanism, and suspend the roughening and cleaning mechanism on the surface to be roughened of the cylindrical pier;

[0010] Mobile high-pressure cleaning: Start the winch and the roughening cleaning mechanism, and use the winch to move the roughening cleaning mechanism axially along the surface to be roughened of the cylindrical pier. During the axial movement, the roughening cleaning mechanism uses a high-pressure water jet to perform high-pressure cleaning on the surface to be roughened;

[0011] When the winch moves the chiseling and cleaning mechanism axially to the axial edge position of the surface to be chiseled, the track support mechanism is rotated to change the high-pressure water jet sprayed by the chiseling and cleaning mechanism, and the chiseling and cleaning mechanism is moved axially in the reverse direction to the initial position through the winch, completing a cycle cleaning operation;

[0012] Circular high-pressure cleaning: After completing a cyclic cleaning operation, the track support mechanism is rotated again in the same direction to change the high-pressure water jet sprayed by the roughening cleaning mechanism, and the cyclic cleaning operation is repeated several times to complete the surface roughening operation of the cylindrical pier.

[0013] In one embodiment, the suspension support mechanism includes an upper steel belt, a lower steel belt, a plurality of inclined tubes and a horizontal tube. The steps of installing the suspension support mechanism specifically include:

[0014] The upper steel belt and the lower steel belt are respectively installed and fixed above the surface of the cylindrical bridge pier to be roughened, and rubber gaskets are arranged between the upper steel belt and the cylindrical bridge pier, and between the lower steel belt and the cylindrical bridge pier;

[0015] One end of a plurality of inclined tubes is evenly connected to the upper steel belt, and one end of a plurality of horizontal tubes is evenly connected to the lower steel belt;

[0016] The ends of the plurality of inclined-stayed tubes away from the upper steel belt are connected and fixed with the ends of the plurality of horizontal tubes away from the lower steel belt.

[0017] In one embodiment, the track support mechanism includes an upper annular track, a lower annular track, a fixing plate and a hanging plate, and the steps of installing the track support mechanism specifically include:

[0018] The fixing plate is installed on the upper ring track, and the upper ring track is fixedly connected to the horizontal pipe through the fixing plate;

[0019] Connect the upper end of the hanging plate to the upper ring track, and buckle the lower end of the hanging plate to the lower ring track;

[0020] Install the winch at the bottom of the hanging plate.

[0021] In one embodiment, the chiseling and cleaning mechanism comprises a support ring, a connecting block mounted on the support ring, and a plurality of water jet elastic modules. The steps of installing the chiseling and cleaning mechanism specifically include:

[0022] The connecting block on the support ring is hooked by a winch, so that the support ring and a plurality of water jet elastic modules on the support ring are suspended on the surface to be roughened of the cylindrical pier.

[0023] In one embodiment, the surface to be roughened of the cylindrical bridge pier is divided into cleaning areas equal to the number of water jet elastic modules, and each cleaning area is cleaned by a water jet elastic module. The mobile high-pressure cleaning step specifically includes:

[0024] The winch and the water jet elastic module in the roughening and cleaning mechanism are started, and the roughening and cleaning mechanism is moved axially along the roughening surface of the cylindrical pier by the winch. During the axial movement, a plurality of water jet elastic modules spray high-pressure water jets toward the corresponding cleaning areas of the roughening surface, and the high-pressure water jets are used to perform high-pressure cleaning on the roughening surface;

[0025] When the winch moves the roughening and cleaning mechanism axially to the axial edge position of the surface to be roughened, the lower annular track in the track support mechanism is rotated to allow the hanging plate to drive the winch, the support ring and the water jet elastic module to rotate accordingly, so that the high-pressure water jet of each water jet elastic module is changed to clean the remaining area in the cleaning area, and the roughening and cleaning mechanism is moved axially in the reverse direction to the original position by the winch to complete a cycle cleaning operation.

[0026] In one embodiment, the water jet elastic module includes a mounting portion, an elastic portion, a contact wheel, and a water jet nozzle;

[0027] The mounting portion is mounted on the supporting ring, one end of the elastic portion is connected to the mounting portion, and the other end of the elastic portion is arranged toward the roughened surface. The contact wheel and the water jet nozzle are both arranged on the end surface of the elastic portion close to the roughened surface. The contact wheel is closer to the roughened surface of the cylindrical pier than the water jet nozzle, so as to prevent the covering of the roughened surface from damaging the water jet nozzle during the axial movement of the roughened cleaning mechanism.

[0028] The construction process of the chiseling and cleaning equipment based on cylindrical bridge piers provided in the above embodiments has the following beneficial effects:

[0029] 1. This construction process can not only meet the needs of cleaning and roughening cylindrical piers, but also adapt to the roughening operations of cylindrical piers with different radii by adjusting the parameters of the high-pressure water nozzle and the steel belt diameter of the roughening and cleaning equipment. In addition, the roughening and cleaning equipment can also be used as a platform to carry different equipment to perform other operations on the surface of the cylindrical pier.

[0031] 3. Compared with traditional manual technology, this construction process is automatic and efficient. It can carry out large-scale rapid pier roughening operations through a combination of axial movement and rotation. Its water jet elastic module can effectively adapt to the complex working conditions of the roughened surface (biological attachment, pits, pitting, cracks, etc. on the roughened surface). Secondly, the diameter of the steel belt can be adjusted according to different piers, and it has a wide range of adaptability. Finally, the equipment has a simple structure, is easy to operate, and has the potential for large-scale promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Reference Figure 1-Figure 9 One embodiment of the present invention provides a construction process of a chiseling and cleaning equipment based on a cylindrical bridge pier. The chiseling and cleaning equipment is composed of a suspension support mechanism 200, a track support mechanism 300 and a chiseling and cleaning mechanism 400.

[0048] The suspension support mechanism 200 includes an upper steel belt 210 , a lower steel belt 220 , a plurality of inclined tubes 230 and a horizontal tube 240 .

[0049] The track support mechanism 300 includes an upper annular track 310 , a lower annular track 320 , a fixing plate 330 and a hanging plate 340 .

[0050] The roughening and cleaning mechanism 400 includes a support ring 410, a connecting block 420 installed on the support ring 410, and a plurality of water jet elastic modules 430; the connecting block 420 adopts a snap buckle; the water jet elastic module 430 includes a mounting portion 431, an elastic portion 432, a contact wheel 433 and a water jet nozzle 434, the mounting portion 431 is installed on the support ring 410, one end of the elastic portion 432 is connected to the mounting portion 431, and the other end of the elastic portion 432 is arranged toward the roughening surface 110, and the contact wheel 433 and the water jet nozzle 434 are both arranged on the end face of the elastic portion 432 close to the roughening surface 110; because there is an irregular covering on the roughening surface, the contact wheel 433 is closer to the roughening surface 110 of the cylindrical pier 100 than the water jet nozzle 434, so as to prevent the irregular covering of the roughening surface 110 from damaging the water jet nozzle 434 during the axial movement of the roughening and cleaning mechanism 400.

[0051] The roughened surface 110 of the cylindrical bridge pier 100 is divided into cleaning areas equal in number to the water jet elastic modules 430, and each cleaning area is cleaned by one water jet elastic module 430. In this embodiment, there are eight water jet elastic modules 430, that is, the roughened surface 110 is divided into eight cleaning areas, each cleaning area occupies 1 / 8 of the area, and each cleaning area is cleaned by one water jet elastic module 430.

[0052] The construction process includes the following steps:

[0053] S100, pre-operation: measuring the size of the cylindrical bridge pier 100, selecting upper and lower steel strips and rubber gaskets of corresponding sizes, and preparing corresponding carriers (cars, ships).

[0054] S200, Transportation: Use carriers to transport the components of each mechanism to the construction site.

[0055] S300 , installation of the suspension support mechanism 200 : installing and fixing the suspension support mechanism 200 above the surface 110 to be roughened of the cylindrical pier 100 .

[0056] The specific installation process is: the upper steel belt 210 and the lower steel belt 220 are respectively installed and fixed on the upper side of the roughened surface 110 of the cylindrical bridge pier 100 by bolts, welding, etc. Figure 2 As shown, rubber gaskets are arranged between the upper steel belt 210 and the cylindrical bridge pier 100, and between the lower steel belt 220 and the cylindrical bridge pier 100, so as to prevent the upper steel belt 210 and the lower steel belt 220 from sliding during construction, thereby playing an anti-skid role;

[0057] One end of a plurality of inclined tubes 230 is evenly connected to the upper steel belt 210, and one end of a plurality of horizontal tubes 240 is evenly connected to the lower steel belt 220. In the present embodiment, there are three inclined tubes 230 and three horizontal tubes 240, which are evenly spaced on the upper steel belt 210 and the lower steel belt 220 to increase stability during support.

[0058] The ends of several inclined tubes 230 away from the upper steel belt 210 are connected and fixed to the ends of several horizontal tubes 240 away from the lower steel belt 220, so that the inclined tubes 230, horizontal tubes 240, upper steel belt 210 / lower steel belt 220 are subjected to force in a triangular shape, thereby increasing the stability during support.

[0059] S400 , installing the track support mechanism 300 : connecting the track support mechanism 300 to the suspension support mechanism 200 , and installing the hoist 500 on the track support mechanism 300 .

[0060] The specific installation process is: install the fixing plate 330 on the upper ring track 310, and fix the upper ring track 310 to the horizontal pipe 240 through the fixing plate 330;

[0061] Connect the upper end of the hanging plate 340 to the upper ring track 310, and buckle the lower end of the hanging plate 340 to the lower ring track 320;

[0062] The hoist 500 is installed at the bottom of the hanging plate 340 .

[0063] like Figure 4 As shown, three hanging plates 340 are also used, each for installing a winch 500; the hanging plate 340 is composed of an upper shell 341, a lower shell 342, a slide 343 and a hook 344; the upper shell 341 and the lower shell 342 are fixed with bolts, and a slide groove is formed between the upper shell 341 and the lower shell 342, and the slide 343 is installed in the slide groove, that is, the inner side of the upper shell 341 and the inner side of the lower shell 342 are both installed with a slide 343, and the hook 344 is fixed to the lower end of the lower shell 342. During installation, the slide groove at the upper end of the hanging plate 340 is connected to the upper circular track 310, so that the hanging plate 340 can slide along the upper circular track 310; the hook 344 at the lower end of the hanging plate 340 is buckled and fixed on the lower circular track 320, so that the entire hanging plate 340 is more stable when sliding along the upper circular track 310; the eye screw is installed on the bottom surface of the hook 344, and the winch 500 is installed on the bottom surface of the hook 344 using the eye screw.

[0064] S500 , installation of the roughening and cleaning mechanism 400 : using the winch 500 on the track support mechanism 300 to hook the roughening and cleaning mechanism 400 , so that the roughening and cleaning mechanism 400 is suspended on the surface to be roughened 110 of the cylindrical pier 100 .

[0065] The specific installation process is: use the winch 500 to hook the connection block 420 on the support ring 410, so that the support ring 410 and a plurality of water jet elastic modules 430 on the support ring 410 are suspended on the surface 110 to be roughened of the cylindrical pier 100.

[0066] like Figure 5 As shown, the winch 500 has an iron ring chain (or steel wire) and a hook. When the track support mechanism 300 is installed, the three winches 500 simultaneously lower the iron ring chain and the hook, and use the hook to hook the connecting blocks 420 on the support ring 410 respectively, so that the support ring 410 and the water jet elastic module 430 on the support ring 410 are suspended on the roughened surface 110 of the cylindrical pier 100.

[0067] It should be noted that the support ring 410 of the roughening and cleaning mechanism 400 is composed of two semicircles. In step S200, after the components of each mechanism are transported to the construction site, the roughening and cleaning mechanism 400 is floated on the water surface using a foam bucket or other floating objects, and the two semicircles of the support ring 410 are buckled on the cylindrical bridge pier 100, waiting for the winch 500 to hook the roughening and cleaning mechanism 400 and suspend it on the roughening surface 110 of the cylindrical bridge pier 100. After the winch 500 hooks the roughening and cleaning mechanism 400, the foam bucket is removed.

[0068] S600, mobile high-pressure cleaning: start the hoist 500 and the roughening cleaning mechanism 400, use the hoist 500 to move the roughening cleaning mechanism 400 axially along the roughening surface 110 of the cylindrical pier 100, and during the axial movement, the roughening cleaning mechanism 400 performs high-pressure cleaning on the roughening surface 110 by a high-pressure water jet;

[0069] When the winch 500 moves the roughening and cleaning mechanism 400 axially to the axial edge position of the surface to be roughened 110, the track support mechanism 300 is rotated to change the high-pressure water jet sprayed by the roughening and cleaning mechanism 400, and the roughening and cleaning mechanism 400 is moved axially in the reverse direction to the original position through the winch 500, completing a cycle cleaning operation.

[0070] Specifically, the hoist 500 and the water jet elastic module 430 in the roughening and cleaning mechanism 400 are started, and the roughening and cleaning mechanism 400 is moved axially (i.e., upward or downward) along the roughening surface 110 of the cylindrical pier 100 by using the hoist 500. During the axial movement, a plurality of water jet elastic modules 430 spray high-pressure water jets toward the corresponding cleaning areas of the roughening surface 110, and the high-pressure water jets are used to perform high-pressure cleaning on the roughening surface 110;

[0071] When the winch 500 axially moves the chiseling and cleaning mechanism 400 to the axial edge position of the chiseled surface 110 (i.e., moves upward or downward to the highest position or the lowest position of the chiseled surface 110), the lower annular track 320 in the track support mechanism 300 is manually rotated, so that the hanging plate 340 drives the winch 500, the support ring 410, and the water jet elastic module 430 to rotate accordingly, as shown in FIG. Figure 8 As shown, the lower annular track 320 is rotated in one direction to change the high-pressure water jet of each water jet elastic module 430 to clean the remaining area in the cleaning area, and the chiseling and cleaning mechanism 400 is moved axially in the reverse direction to the initial position by the winch 500 to complete a cycle cleaning operation.

[0072] like Fig. 9As shown, for example, the initial position of the chiseling and cleaning mechanism 400 is located at the highest position of the chiseling surface 110. When the chiseling begins, the winch 500 is used to control the chiseling and cleaning mechanism 400 to move downward to the lowest position of the chiseling surface 110. Taking the cleaning of a cleaning area by a single water jet elastic module 430 as an example, during the downward movement, the water jet elastic module 430 uses a high-pressure water jet to perform high-pressure cleaning on the surface 110 to be chiseled. When it moves to the lowest position of the chiseling surface 110, the lower circular track 320 is rotated in one direction to change the high-pressure water jet of the water jet elastic module 430, and then the winch 500 controls the chiseling and cleaning mechanism 400 to move upward to the highest position of the chiseling surface 110. During the movement, the high-pressure water jet is also used to perform high-pressure cleaning on the surface 110 to be chiseled. When the chiseling and cleaning mechanism 400 moves back to the initial position, a cycle cleaning operation is completed; the remaining water jet elastic modules 430 clean the remaining cleaning areas in the same way.

[0073] As needed, a number of detection cameras are provided on the support ring 410 of the roughening and cleaning mechanism 400, which are used to obtain image information of the surface 110 to be roughened of the cylindrical pier 100, and to automatically control the start and stop of the winch 500 according to the obtained image information. That is, when the winch 500 controls the roughening and cleaning mechanism 400 to move axially, the detection camera obtains that the roughening and cleaning mechanism 400 is located at the axial edge position of the surface 110 to be roughened, and then controls the winch 500 to stop, so as to improve the cleaning efficiency of the surface 110 to be roughened of the cylindrical pier 100, and avoid the roughening and cleaning mechanism 400 from cleaning the surface of the cylindrical pier 100 that does not need to be roughened and cleaned.

[0074] S700, cyclic high-pressure cleaning: after completing one cyclic cleaning operation, the track support mechanism 300 is rotated again in the same direction to change the high-pressure water jet sprayed by the roughening cleaning mechanism 400, and the cyclic cleaning operation is repeated several times to complete the surface roughening operation of the cylindrical bridge pier 100.

[0075] like Fig. 9As shown, taking the cleaning of a cleaning area by a single water jet elastic module 430 as an example, after completing one cycle of cleaning operation, the lower circular track 320 is rotated again in the same direction, and the winch 500 and the water jet elastic module 430 are controlled to repeat the above cleaning action to repeat multiple cycles of cleaning operations to complete the roughening operation of the overall roughening surface 110; since the roughening surface 110 to be roughened is divided into eight cleaning areas, the area of ​​the roughening surface 110 occupied by each cleaning area is 1 / 8, and the total angle of the cleaning area cleaned by a single water jet elastic module 430 is 45°. If the rotation angle is 7.5° each time, the area cleaned by one cycle of cleaning operation is 1 / 3, that is, the total angle of one cycle of cleaning operation is 15°. At this time, the surface roughening operation of the cylindrical pier 100 can be completed by repeating the cycle of cleaning operation twice.

[0076] S800, equipment recovery: After the roughening operation on the surface of the cylindrical bridge pier 100 is completed, the foam bucket is fixed on the roughening and cleaning mechanism 400 to make it float on the water surface, and the hook and iron ring chain of the winch 500 are unhooked, and then it is connected to the transport vehicle to complete the recovery operation of the roughening and cleaning mechanism 400. The remaining mechanisms and components are disassembled in the reverse order of installation and moved to the transport vehicle to complete the recovery operation of the entire equipment.

[0077] This construction process can not only meet the needs of cleaning and roughening cylindrical bridge piers, but also adapt to the roughening operation of cylindrical bridge piers of different radii by adjusting the parameters of the high-pressure water nozzle and the steel belt diameter of the roughening cleaning equipment. In addition, the roughening cleaning equipment can also be used as a platform to carry different equipment to perform other operations on the surface of cylindrical bridge piers. The overall construction process has a wide range of applications, low cost, simple structure, and easy operation; compared with other roughening methods, this process is safer, more stable, and more convenient for corresponding construction operations on cylindrical bridge piers. Compared with traditional manual technology, this construction process is automatic and efficient, and can perform large-scale rapid bridge pier roughening operations by combining axial movement and rotation. Its water jet elastic module can effectively adapt to the complex working conditions of the roughening surface (biological attachment, pits, pits, cracks, etc. on the roughening surface). Secondly, the steel belt diameter can be adjusted according to different bridge piers, and it has a wide range of adaptability. Finally, the equipment has a simple structure, easy operation, and has the potential for large-scale promotion.

[0078] As needed, the above-mentioned installation, setting, provision or connection methods include but are not limited to installation, setting or connection by screws, riveting, welding or socketing, fixing, etc., and the installation, setting or connection method is selected according to the needs of the working scenario.

The steps of installing the chiseling and cleaning mechanism specifically include: The connecting block on the support ring is hooked by a winch, so that the support ring and a plurality of water jet elastic modules on the support ring are suspended on the surface to be roughened of the cylindrical pier.

5. The construction process of the chiseling and cleaning equipment based on cylindrical bridge piers as claimed in claim 4, characterized in that: The surface to be roughened of the cylindrical bridge pier is divided into cleaning areas with the same number as the water jet elastic modules, and each cleaning area is cleaned by a water jet elastic module. The mobile high-pressure cleaning step specifically includes: The winch and the water jet elastic module in the roughening and cleaning mechanism are started, and the roughening and cleaning mechanism is moved axially along the roughening surface of the cylindrical pier by the winch. During the axial movement, a plurality of water jet elastic modules spray high-pressure water jets toward the corresponding cleaning areas of the roughening surface, and the high-pressure water jets are used to perform high-pressure cleaning on the roughening surface; When the winch moves the roughening and cleaning mechanism axially to the axial edge position of the surface to be roughened, the lower annular track in the track support mechanism is rotated to allow the hanging plate to drive the winch, the support ring and the water jet elastic module to rotate accordingly, so that the high-pressure water jet of each water jet elastic module is changed to clean the remaining area in the cleaning area, and the roughening and cleaning mechanism is moved axially in the reverse direction to the original position by the winch to complete a cycle cleaning operation.

6. The construction process of the chiseling and cleaning equipment based on cylindrical bridge piers as claimed in claim 4, characterized in that: The water jet elastic module comprises a mounting portion, an elastic portion, a contact wheel and a water jet nozzle; The mounting portion is mounted on the supporting ring, one end of the elastic portion is connected to the mounting portion, and the other end of the elastic portion is arranged toward the roughened surface. The contact wheel and the water jet nozzle are both arranged on the end surface of the elastic portion close to the roughened surface. The contact wheel is closer to the roughened surface of the cylindrical pier than the water jet nozzle, so as to prevent the covering of the roughened surface from damaging the water jet nozzle during the axial movement of the roughened cleaning mechanism.
