Description

Technical Field

[0001] The utility model relates to the technical field of maintenance devices, in particular to a road and bridge maintenance device. Background Art

[0002] In road and bridge maintenance work, high-pressure cleaning machines are key equipment for removing stains, debris and dirt in structural gaps on the bridge surface. Their performance directly affects the maintenance efficiency and quality. At present, high-pressure cleaning machines are mainly divided into two types: with water tanks and without water tanks. Cleaning machines without water tanks rely on external water sources. When operating on bridge sections with scarce water sources, additional water pipes need to be laid or pumping equipment needs to be equipped, which has poor flexibility. Although cleaning machines with water tanks solve the water storage problem, the traditional fixed water tank design has obvious defects.

[0003] In existing high-pressure cleaning machines with water tanks, the water tanks are mostly rigid structures, fixedly installed on the frame of the cleaning machine base, often occupying nearly half of the frame space, and the tank body is mostly made of ordinary metal or plastic. Due to the complex on-site environment of road and bridge maintenance, the equipment often faces bumps and vibrations during movement, and even collisions with guardrails, stones, etc. This type of rigid water tank has weak protective performance and is prone to wear, deformation or leakage.

[0004] In addition, traditional water tanks still occupy a fixed space when not in use and cannot flexibly adjust their volume according to water storage needs, resulting in a decrease in the overall portability of the equipment. When operating outdoors, the exposed water tanks are also susceptible to the influence of the natural environment, such as high temperature exposure accelerating material aging, and low temperature causing internal water to freeze and crack, further shortening the service life of the equipment.

[0005] Based on this, the utility model designs a road and bridge maintenance device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a road and bridge maintenance device.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A road and bridge maintenance device includes a cleaning machine base plate, universal wheels, mobile wheels, a high-pressure pump support frame, a high-pressure pump, a water outlet pipe, and a water inlet pipe. The universal wheels are symmetrically mounted on the bottom surface of the cleaning machine base plate, and the mobile wheels are symmetrically mounted on the bottom surface of one end of the cleaning machine base plate away from the universal wheels. The high-pressure pump support frame is fixedly connected to the top surface of the cleaning machine base plate, and the housing of the high-pressure pump is fixedly connected to the surface of the high-pressure pump support frame. The output end of the high-pressure pump is fixedly connected to the water outlet pipe and the water inlet pipe, and includes a water storage component and a protective component.

[0009] The water storage assembly includes a foldable water storage bag, which is installed on the top surface of the cleaning machine bottom plate on a side away from the high-pressure pump support frame;

[0010] The protection component comprises a retractable baffle plate, the bottom surface of which is located on the top surface of the bottom plate of the cleaning machine, and the retractable baffle plate is arranged around the foldable water storage bag.

[0011] Furthermore, the water storage assembly also includes a connecting pipe, and a connecting port is opened on a side wall of the foldable water storage bag facing the high-pressure pump. The connecting pipe is fixedly connected to the inner wall of the connecting port, and the connecting pipe is connected to the foldable water storage bag.

[0012] Furthermore, a mounting groove is provided on the top surface of the bottom plate of the cleaning machine, the bottom surface of the foldable water storage bag is fixed at the center of the bottom surface of the mounting groove, and the retractable baffle is located on the inner wall of the mounting groove.

[0013] Furthermore, the protective component also includes a retractable baffle, and the retractable baffle is greater than one, and the top surface of each retractable baffle is provided with a connecting groove that passes through the bottom surface of the retractable baffle. The top end of the top retractable baffle is fixedly connected to a covering plate, and the covering plate is normally attached to the top surface of the foldable water storage bag.

[0014] Furthermore, a symmetrical slide groove is opened on the inner wall of the connecting groove, the bottom end of the slide groove is through-type, a slider is slidably connected to the inner wall of the slide groove, and the slider is fixedly connected to the bottom side wall of the retractable partition plate.

[0015] Furthermore, a notch is formed on a side wall of the retractable baffle close to the connecting pipe, and the opening width of the notch is greater than the outer diameter of the connecting pipe.

[0016] Furthermore, the retractable baffle is made of stainless steel.

[0017] Compared with the existing technology, the beneficial effects of the present invention are as follows: 1. The road and bridge maintenance device improves the practicality of the equipment through the foldable water storage bag and the retractable baffle. The foldable water storage bag expands to store water when filled with water and collapses when idle, solving the problem that the traditional fixed water tank occupies a large amount of space on the bottom plate of the cleaning machine, optimizing the spatial layout, and enhancing the portability of the equipment. At the same time, the foldable water storage bag is connected to the water inlet pipe through a connecting pipe thread, which is convenient for installation and disassembly. Compared with the traditional fixed water tank, the difficulty of replacement is greatly reduced, the maintenance time and cost are reduced, and the continuity of maintenance operations is guaranteed;

[0018] 2. The design of the protective component further improves the performance of the equipment. The retractable baffle made of stainless steel is set around the foldable water storage bag. When the foldable water storage bag is saturated, it is propped up to resist collisions and bumps. When stored, it moves down to form external protection. This effectively solves the problems of poor protection and easy wear of traditional water tanks, extends the life of the water storage components, and makes the equipment more adaptable and convenient to use in complex outdoor bridge maintenance scenarios.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] In some embodiments, please refer to the accompanying drawings of the specification. Figure 1-Figure 5 , a road and bridge maintenance device includes a cleaning machine base plate 1, a universal wheel 2, a moving wheel 3, a high-pressure pump support frame 4, a high-pressure pump 5, a water outlet pipe 6, and a water inlet pipe 7. The universal wheel 2 is symmetrically installed on the bottom surface of the cleaning machine base plate 1, and the moving wheel 3 is symmetrically installed on the bottom surface of the cleaning machine base plate 1 away from the universal wheel 2. The high-pressure pump support frame 4 is fixedly connected to the top surface of the cleaning machine base plate 1, and the shell of the high-pressure pump 5 is fixedly connected to the surface of the high-pressure pump support frame 4. The output end of the high-pressure pump 5 is fixedly connected with the water outlet pipe 6 and the water inlet pipe 7, including a water storage component and a protective component; the water storage component includes a foldable water storage bag 9, which is installed on the side of the top surface of the cleaning machine base plate 1 away from the high-pressure pump support frame 4; the protective component includes a retractable stainless steel baffle 12, the bottom surface of the retractable baffle 12 is located on the top surface of the cleaning machine base plate 1, and the retractable baffle 12 surrounds the foldable water storage bag 9 The arrangement is such that when the high-pressure cleaning machine for road and bridge maintenance is in use, the water-filled state of the foldable water storage bag 9 can be utilized to prop up the retractable baffles 12 one by one. During the process, not only can the foldable water storage bag 9 have a saturated water storage state confined to the inside of the retractable baffles 12, but also after the foldable water storage bag 9 is saturated, the propped-up state of the retractable baffles 12 can be utilized to protect the foldable water storage bag 9 in use. In addition, when the foldable water storage bag 9 is not needed, it can be in a flattened state, and the retractable baffles 12 can also be moved down and retracted to provide external protection for the flattened foldable water storage bag 9. Compared with the high-pressure cleaning machine with a water tank in the prior art, the optimization of this technical solution can make the foldable water storage bag 9 protected and stored for use, and always have a protected effect to avoid wear and tear that reduces its service life. When used outdoors for road and bridge maintenance, it can avoid damage due to collision and friction.

[0029] Among them, the high-pressure water pump 5 in this technical solution is a three-cylinder plunger pump with a flow rate of 15-25L / min and a pressure of 15-20MPa. The water outlet pipe 6 needs to withstand the strong output pressure of the high-pressure water pump 5. Therefore, it is recommended to use a high-pressure steel wire braided hose with an inner diameter of 8-10mm, a working pressure of not less than 25MPa, and a threaded interface of M22×1.5. The water inlet pipe 7 is a PVC reinforced hose, and the connecting pipe 11 adopts a copper or stainless steel pipe with an outer diameter of 20-25mm and a length of 15-20cm. It is sealed and fixed with the connecting port 10 of the foldable water storage bag 9 by hot melting. The foldable water storage bag 9 is made of high-strength PVC composite material.

[0030] In some embodiments, as Figure 2 and Figure 3As shown, as a preferred embodiment of the present invention, the water storage assembly also includes a connecting pipe 11, and a connecting port 10 is provided on the side wall of the foldable water storage bag 9 facing the high-pressure pump 5. The connecting pipe 11 is fixedly connected to the inner wall of the connecting port 10, and the connecting pipe 11 is communicated with the foldable water storage bag 9, wherein the surface of the water inlet pipe 7 and the connecting pipe 11 are provided with threaded grooves, which can facilitate maintenance operations of the external water pipe.

[0031] In some embodiments, as Figure 1-3 As shown, as a preferred embodiment of the present invention, a mounting groove 8 is provided on the top surface of the bottom plate 1 of the cleaning machine, and the bottom surface of the foldable water storage bag 9 is fixed at the center of the bottom surface of the mounting groove 8. The retractable baffle 12 is located on the inner wall of the mounting groove 8. The foldable water storage bag 9 is fixed at the center of the bottom surface of the mounting groove 8, which can prevent it from shifting or shaking during water injection and equipment movement, and ensure that the foldable water storage bag 9 is always within the surrounding protection range of the retractable baffle 12, thereby ensuring the stability of the protection effect. The retractable baffle 12 is located on the inner wall of the mounting groove 8, which allows it to move along the trajectory of the mounting groove 8 when shrinking or extending, reducing the occurrence of skewness, jamming, etc., making the telescopic action of the retractable baffle 12 smoother, thereby ensuring reliable switching of the protection state of the foldable water storage bag 9.

[0032] In some embodiments, as Figure 1-5As shown, the protective component also includes a retractable baffle 12, and the retractable baffle 12 is greater than one, and the top surface of each retractable baffle 12 is provided with a connecting groove 13 that passes through the bottom surface of the retractable baffle 12, and the top of the top retractable baffle 12 is fixedly connected to a cover plate 16, and the cover plate 16 is normally attached to the top surface of the foldable water storage bag 9, and the inner wall of the connecting groove 13 is provided with a symmetrical slide groove 14, the bottom end of the slide groove 14 is through-type, and the inner wall of the slide groove 14 is slidably connected to a slider 15, and the slider 15 is fixedly connected to the bottom side wall of the retractable baffle 12, wherein each retractable baffle 12 is hollow, and the connecting groove 13 is provided on the top surface of each retractable baffle 12, but the top surface of the topmost retractable baffle 12 does not have a connecting groove 13, and the top surface of the topmost retractable baffle 12 is used to be fixedly connected to the cover plate 16 , it is convenient to protect the top of the foldable water storage bag 9, the slider 15 is symmetrically fixed to the bottom side wall of the retractable baffle 12 except for the bottom end. When the protective component is extended, the slider 15 is completely invisible from the outside. A notch 17 is provided on one side wall of the retractable baffle 12 close to the connecting pipe 11, and the opening width of the notch 17 is larger than the outer diameter of the connecting pipe 11. When the retractable baffle 12 is in the retracted state, the notch 17 is sleeved on the outside of the connecting pipe 11. When the retractable baffle 12 is extended, the notch 17 moves upward with the retractable baffle 12 at equal distances. The opening of the notch 17 can prevent the connecting pipe 11 from being unable to connect to the water pipe normally. It is particularly noted that the number of retractable baffles 12 is greater than 1 to adapt to the state where the foldable water storage bag 9 is fully saturated, and can be welded to form a protective component according to the actual capacity volume of the foldable water storage bag 9.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
