Description

Technical Field

[0001] The utility model relates to the technical field of concrete roughening, in particular to a high-pressure water jet concrete roughening device. Background Art

[0002] Common concrete diseases in the highway field include concrete cracks, concrete spalling, and concrete breakage and exposed reinforcement. During maintenance, roughening must be performed to remove the surface concrete to expose the new concrete surface, facilitate subsequent concrete pouring, and increase the bonding strength between the new and old concrete. Similarly, in the renovation of various old concrete floors, removal of protrusions or epoxy resin on the surface of damaged concrete floors, making anti-slip floors, roughening the beam surface and both wings of prefabricated box beams, and reinforcement construction of highway railway tunnels and other concrete buildings, in order to facilitate the combination of new and old concrete, it is necessary to roughen or chisel the surface of the old concrete in advance to make the surface have a certain degree of roughness to ensure the bonding strength between the subsequent concrete pouring.

[0003] In traditional concrete roughening work, manual handheld chisels, pneumatic picks, rock hammers and other mechanical tools are mainly used for roughening operations to remove the concrete surface and expose the new concrete surface, so that the new and old concrete can be firmly bonded. However, the traditional roughening method has many disadvantages, such as poor roughening quality, poor roughening uniformity, long roughening time, high labor intensity, dust flying, high construction noise, vibration force and sound wave transmission will cause damage to the original concrete structure, and the roughening equipment will be damaged by the anti-vibration effect, affecting its service life. In addition, for special concrete structures such as vertical walls or slopes, existing roughening tools are not convenient for construction operations.

[0004] For example, the Chinese patent "CN214939103U" discloses "a high-pressure water roughening device for airport pavement". The device uses a servo motor to rotate forward and reverse to drive the second gear. The second gear drives the sawtooth on the slide bar to make the slide bar reciprocate. The high-pressure nozzle in the middle of the slide bar also sweeps back and forth with the slide bar to roughen. The high-pressure nozzle sprays water downward to generate an upward force on the slide bar, reducing the friction of the slide bar on the slide rail mouth. After the above search and understanding of the existing devices, it is known that although the high-pressure nozzle of the above-mentioned equipment can reciprocate through the slide bar to roughen, because the direction and connection method of the high-pressure nozzle are relatively fixed, when roughening the side wall or inclined surface, or roughening the groove, other equipment needs to be replaced, and the applicability is poor.

DETAILED DESCRIPTION

[0031] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1 As shown, the embodiment of the utility model provides a high-pressure water jet concrete roughening device, comprising:

[0033] Mounting frame 1;

[0034] The high-pressure water delivery unit comprises a high-pressure pump 2, a water storage tank 3 and a waterway plate 6 located at the bottom of the mounting frame 1, the waterway plate 6 is provided with a water inlet and a plurality of nozzles 7 connected to the water inlet, the water storage tank 3 is connected to the high-pressure pump 2 through a high-pressure pipe, and the high-pressure pump 2 is connected to the water inlet of the waterway plate 6 through another high-pressure pipe;

[0035] The telescopic rod and the mounting frame 1 are provided with a fixed frame 17, the telescopic rod is slidably arranged on the fixed frame 17, the waterway plate 6 is rotatably arranged on the end of the telescopic rod, and the end of the telescopic rod is provided with an adjusting member connected to the waterway plate 6 for adjusting the spraying angle of the waterway plate 6.

[0036] In the embodiment of the utility model, the high-pressure water supply unit and the telescopic rod are supported by the mounting frame 1. When the target area is roughened by the high-pressure water supply unit, no manual holding is required, which not only ensures the stability of the nozzle 7 during roughening, improves the quality of roughening, and ensures the normal construction progress, but also avoids the impact of roughening to cause harm to the human body. The water jet roughening method will not cause too much noise and can also prevent a large amount of dust from being generated during roughening.

[0037] Specifically, the mounting frame 1 is provided with a plurality of legs 19, and each of the legs 19 is provided with load-bearing wheels 20 for movement. The mounting frame 1 on which the high-pressure water delivery unit and the telescopic rod are installed can be supported by the plurality of legs 19, and can be moved under the action of the load-bearing wheels 20, so as to facilitate the high-pressure water delivery unit to perform mobile roughening operations.

[0038] When the target area is roughened by the high-pressure water delivery unit, the water tank 3 is a water inlet with a cover. The water source to be used is poured into the water tank 3 from the water inlet for storage, and then the high-pressure pump 2 is turned on to pump the water in the water tank 3 and deliver it to the waterway plate 6. The high-pressure water flow is sprayed out through each nozzle 7 on the waterway plate 6 to impact the target area, so as to roughen the target area. During the roughening process, the position of the waterway plate 6 can be raised or lowered by the action of the telescopic rod, so that the distance between each nozzle 7 and the target area is changed, thereby accurately controlling the target distance. In addition, when roughening the groove, the waterway plate 6 can also be moved to the inside of the groove by the action of the telescopic rod to roughen the bottom of the groove. It can be used according to actual work needs. The telescopic rod is connected to the waterway plate 6 through an adjusting piece, and the waterway plate 6 can be rotated and fixed by the adjusting piece, so as to adjust the spray angle of each nozzle 7 in the waterway plate 6. The adjusted waterway plate 6 can use each nozzle 7 to roughen the road side, piers, groove sides and inclined surfaces, thereby increasing the scope of use of the present solution, improving applicability, and ensuring that it can be used in various construction sites.

[0039] Based on the above scheme, if Figure 3 As shown, the telescopic rod includes a support frame 4 and a mobile frame 5 slidably arranged in the support frame 4, a waterway plate 6 is arranged at one end of the mobile frame 5, and a second screw rod 9 is rotatably arranged on the support frame 4, and the second screw rod 9 passes through one side of the mobile frame 5 and is threadedly connected with one side of the mobile frame 5. Specifically, when adjusting the telescopic rod, the support frame 4 of the telescopic rod is a fixed end, and the length of the support frame 4 is always guaranteed to remain unchanged during adjustment. By rotating the second screw rod 9, the second screw rod 9 is rotated on the support frame 4, so that the mobile frame 5 inside the support frame 4 can be driven by the second screw rod 9 and slowly retracted into the support frame 4 to lift the waterway plate 6, or the mobile frame 5 is gradually moved out of the support frame 4 to increase the distance between the mobile frame 5 and the top of the support frame 4, so as to adjust the waterway plate 6 downward. After the second screw rod 9 stops rotating, it can be self-locking, and the structure is relatively simple and easy to adjust.

[0040] Specifically before and after adjustment Figure 4 , Figure 6 As shown, when the waterway plate 6 is roughening the road surface, the angle between the waterway plate 6 and the telescopic rod is guaranteed to be vertical, so that the waterway plate 6 is parallel to the road surface to be roughened. When the mounting frame 1 moves through the load-bearing wheels 20, the various nozzles 7 on the waterway plate 6 are moved to roughen the road surface. The roughened area is rectangular. When the mobile frame 5 is raised or lowered, the distance between each nozzle 7 and the target area can be increased or decreased, thereby realizing the control of the jet target distance. When roughening the groove, Figure 6In the process, the mounting frame 1 is set on the top of the groove so that the waterway plate 6 faces the groove, and by rotating the second screw 9, the waterway plate 6 is gradually moved into the groove, and the distance between each nozzle 7 and the bottom of the groove is adjusted, and the mounting frame 1 is moved to achieve roughening of the bottom of the groove.

[0041] Based on the above scheme, if Figure 2 As shown, the adjusting member includes a worm gear 15 rotatably arranged on the movable frame 5 and connected to the waterway plate 6. A mounting seat 13 is provided at the end of the movable frame 5, and a worm 14 is rotatably arranged on the mounting seat 13, and the worm 14 is meshed with the worm gear 15; a pin shaft is provided on the side of the waterway plate 6, and the pin shaft passes through the movable frame 5, and a worm gear 15 connected to the pin shaft and a worm 14 meshed with the worm gear 15 are provided on one side of the movable frame 5. Since the worm gear 15 is fixedly connected to the waterway plate 6 by the pin shaft, when adjusting the worm gear 15, it is only necessary to rotate the worm 14. When the worm 14 rotates, the worm gear 15 can be driven to rotate with the pin shaft as the axis, thereby driving the waterway plate 6 to rotate with the pin shaft as the axis, thereby changing the angle between the waterway plate 6 and the movable frame 5.

[0042] When adjusting, first Figure 5 As shown, when roughening the wall, roadside and roadside stone railings, the worm 14 is rotated to drive the worm wheel 15 to rotate, so that the waterway plate 6 is gradually in line with the telescopic rod, and the adjustment of the worm 14 can be stopped. It is worth noting that when the worm 14 is rotated, the direction of each nozzle 7 in the waterway plate 6 can be adjusted by reversing the worm 14 to meet the roughening requirements on both sides of the highway. Since the waterway plate 6 is located in the middle of the mounting frame 1 in the initial state, the telescopic rod is pushed after the adjustment of the waterway plate 6 to make it slide on the fixing frame 17, so that the telescopic rod slides to one side or the other side of the mounting frame 1, and the sliding position is selected to adjust the spacing between each nozzle 7 and the roadside or pier, thereby adjusting the target distance.

[0043] Secondly, Figure 7 As shown, when roughening the inner wall of the groove, after adjusting the waterway plate 6 to be in line with the telescopic rod, the second screw rod 9 is rotated to gradually move the mobile frame 5 stored in the support frame 4, so that the vertically arranged waterway plate 6 is completely moved into the groove, and the telescopic rod is pushed to slide to one side or the other side of the mounting frame 1, and the target distance is controlled to perform roughening. Moreover, in the construction of different grooves, Figure 8As shown, for a groove with a certain slope on the side, when roughening it, first rotate the worm 14 to make the worm wheel 15 rotate to drive the waterway plate 6 and the telescopic rod to form an angle, so that the inclined waterway plate 6 allows each nozzle 7 to correspond to the inclined groove wall in an inclined state, and the centerline angle of the inclined groove wall also changes. When adjusting the target distance, it is necessary to synchronously adjust the length of the telescopic rod and the distance of the telescopic rod on the fixed frame 17, so that the target distance for roughening the inclined groove wall can be accurately controlled.

[0044] Based on the above scheme, if Figure 2 As shown, one side of the mounting seat 13 is provided with an operating knob 16 connected to the worm 14. Under the action of the operating knob 16, it is convenient to manually adjust the worm 14, which is convenient for operation; and as shown Figure 1 and Figure 3 As shown, one end of the first screw rod 8 and one end of the second screw rod 9 are both provided with a hand wheel 21, which is also convenient for manual adjustment of the first screw rod 8 and the second screw rod 9 and facilitates operation.

[0045] like Figure 1 As shown, it also includes a first screw rod 8, which is rotatably arranged on the mounting frame 1. A threaded plate 10 is arranged on the top of the supporting frame 4, and the threaded plate 10 is slidably arranged on the fixing frame 17, and the threaded plates 10 are threadedly connected with each other.

[0046] In the embodiment of the utility model, after the support frame 4 in the telescopic rod is adjusted laterally, in order to ensure its stability, the first screw rod 8 is rotatably installed on the mounting frame 1, and a threaded plate 10 matching the first screw rod 8 is installed on the support frame 4, so that when the first screw rod 8 is rotated forward and reversed, the support frame 4 can be driven to slide left and right on the fixing frame 17. After the first screw rod 8 stops rotating, the support frame 4 can complete self-locking with the cooperation of the thread, avoiding self-displacement under the action of recoil, thereby ensuring stability.

[0047] Further, such as Figure 2 and Figure 3 As shown, a block 11 is provided on the side of the mobile frame 5, and a slot 18 penetrating through the end of the support frame 4 is provided on the inner side of the support frame 4, and the block 11 is slidably engaged in the slot 18; in order to reduce the radial force exerted on the second screw 9, the mobile frame 5 can be limited by the cooperation of the block 11 and the slot 18, which can ensure that the mobile frame 5 will only move along the direction of the slot 18.

[0048] Further, such as Figure 2As shown, the water inlet of the waterway plate 6 is provided with a rotating joint 12, and the rotating joint 12 is connected to one of the high-pressure pipes on the high-pressure pump 2; because the waterway plate 6 needs to be adjusted according to actual conditions during actual use, in order to avoid the high-pressure pipe from twisting and becoming tangled during the adjustment process, the high-pressure pipe and the water inlet of the waterway plate 6 are connected by a rotating joint 12, so that when the waterway plate 6 is rotated to adjust, the rotating joint 12 can be adaptively rotated so that the high-pressure pipe connected thereto will not be disturbed.

[0049] In the present scheme, water is stored in the water tank 3, and the target area is roughened by means of high-pressure water spraying by the high-pressure pump 2, the waterway plate 6 and each nozzle 7. This not only has low noise and does not generate large dust, but also avoids the impact of the roughening on the human body, making it safer during construction and meeting safety standards. Moreover, under the action of the telescopic rod, by adjusting the mobile frame 5 up and down, not only can the target distance be accurately adjusted, but also grooves of different depths can be roughened. By utilizing the action of the adjusting member, the adjustability of the waterway plate 6 is increased, so that the waterway plate 6 can roughen the roadside and columnar buildings with the support of each nozzle 7, and then cooperate with the telescopic member to roughen the inner wall of the groove and the inner wall of the inclined groove, thereby realizing one device with multiple uses, a simple adjustment method, and a low manufacturing cost, which can be applicable to different construction sites.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
