Description

Technical Field

[0001] The utility model belongs to the field of road bridge tunnel engineering, in particular to a road bridge tunnel lining maintenance device. Background Art

[0002] During the construction of roads and bridges, mountains or rivers are often encountered. At this time, it is necessary to build underground tunnels for passage. During the tunnel construction process, tunnel lining technology is usually used. Tunnel lining refers to a permanent structure that supports and maintains the long-term stability and durability of the tunnel to prevent deformation or collapse of the surrounding rock. During the tunnel construction process, maintenance equipment is required to regularly water and maintain the tunnel lining.

[0003] However, in actual use, when the temperature is below 5°C in winter, watering maintenance is not suitable. The tunnel lining will be maintained by spraying concrete curing agent to reduce water loss. Since the curing agent needs to be in direct contact with the concrete, the dirt and attachments formed by the floating dust on the concrete surface after contact with water need to be cleaned in advance during the spraying process to avoid the maintenance effect being affected by impurities as intermediate media.

[0004] The existing cleaning process of the tunnel lining concrete surface requires the use of manual handheld tools for cleaning. Since the height of the tunnel may be high, it is necessary to climb high during the cleaning, which is time-consuming, laborious and very inconvenient.

[0005] Therefore, the utility model proposes a road bridge tunnel lining maintenance device. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a road bridge tunnel lining maintenance device, which solves the problem that the existing tunnel lining maintenance requires manual cleaning of the dirt and attachments on the tunnel lining surface in advance and then spraying the curing agent for maintenance, which results in high labor intensity and poor work efficiency for the workers.

[0007] To achieve the above-mentioned purpose, according to the embodiment of the first aspect of the utility model, a road bridge tunnel lining maintenance device is provided, comprising: a water storage tank and a swing mechanism, a matching water pump is fixedly installed on the top of the water storage tank, a water outlet of the water pump is rotatably connected to a bend pipe, an end of the bend pipe away from the water pump is fixedly connected to an outer pipe, an inner wall of the outer pipe is slidably matched with a telescopic pipe, and a spray head is fixedly connected to the top of the telescopic pipe;

[0010] Preferably, a height adjustment mechanism is installed on one side of the outer tube and the telescopic tube, and the height adjustment mechanism includes a threaded sleeve, a threaded rod and a fixed plate. The threaded sleeve is fixedly installed on one side of the telescopic tube, and the fixed plate is fixedly installed on one side of the outer tube. The threaded rod is adapted to the threaded sleeve, and one end of the threaded rod passes through the fixed plate and extends, and the threaded rod is rotatably connected to the fixed plate.

[0011] Preferably, the hollow tube and the adjusting rod are both provided with limiting holes, and the limiting holes are threadedly connected with hand-tightened bolts.

[0012] Preferably, a connecting seat, a plurality of rollers and a handle are fixedly mounted on the water tank, a water inlet is provided on the top of the water tank, and an observation port is provided on the side panel of the water tank.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 5 As shown, a road bridge tunnel lining maintenance device comprises: a water tank 1, a connection seat 19 and a water pump 2 matched with the water tank 1 are fixedly installed on the top of the water tank 1,

[0027] The water outlet of the water pump 2 is fixedly connected to one end of the connection seat 19, and the other end of the connection seat 19 is rotatably connected to a curved pipe 3, and the curved pipe 3 is fixedly connected to an outer pipe 4 at one end away from the water pump 2, and a telescopic pipe 5 is slidably fitted on the inner wall of the outer pipe 4, and a spray head 7 is fixedly connected to the top of the telescopic pipe 5;

[0028] like Figure 5 As shown, a swing mechanism 14 is installed on the side plate of the water tank 1, and the swing mechanism 14 includes a connecting plate 141, a driving motor 144 and a rotating shaft 146. The driving motor 144 and the rotating shaft 146 are fixedly installed on the side plate of the water tank 1. The rotating shaft 146 is rotatably connected to the connecting plate 141 at one end away from the water tank 1. Two movable openings 142 are provided on the connecting plate 141.

[0029] The output shaft of the driving motor 144 is fixedly mounted with a crank shaft 145, and the crank shaft 145 is inserted and installed in one of the movable openings 142. The swing mechanism 14 also includes a movable rod 143, one end of which is fixedly connected to the curved pipe 3, and the other end is inserted and installed in the other movable opening 142. The movable rod 143 and the crank shaft 145 can slide up and down in the movable opening 142 along the inner wall of the movable opening 142;

[0030] The device forms a flexible spraying system through a water pump 2, a curved pipe 3, an outer pipe 4 and a telescopic pipe 5; the telescopic pipe 5 can slide in the outer pipe 4, thereby adjusting the position of the spraying head 7 to meet the spraying requirements at different distances; this design can ensure that during the maintenance process, water or curing agent can evenly and effectively cover all parts of the tunnel lining, thereby improving the maintenance effect;

[0031] like Figure 3 As shown, a hollow tube 9 is fixedly mounted on the telescopic tube 5, and an adjusting rod 10 is rotatably connected inside the hollow tube 9. A limiting hole 6 is provided on both the hollow tube 9 and the adjusting rod 10, and a hand-tightening bolt 15 is threadedly connected to the limiting hole 6. A plurality of telescopic rods 11 are fixedly mounted on the adjusting rod 10, and a scraper 12 is fixedly mounted on one end of the telescopic rod 11 away from the adjusting rod 10. A spring 13 is also sleeved on the telescopic rod 11, and one end of the spring 13 is fixedly connected to the adjusting rod 10, and the other end is fixedly connected to the scraper 12;

[0032] The scraper 12 and telescopic rod 11 structure arranged on the telescopic tube 5 can realize the rapid cleaning of the tunnel lining surface. The scraper 12 can move with the extension and retraction of the telescopic tube 5 and the swing of the swing mechanism 14, effectively removing the dirt and attachments on the tunnel lining surface. The spring 13 sleeved on the adjustment rod 10 can provide appropriate resistance when the telescopic rod 11 is extended and retracted, so that the scraper 12 maintains a certain pressure during the cleaning process, and the fit between the scraper 12 and the tunnel lining surface can be adjusted, thereby ensuring the cleaning effect.

[0033] When the temperature is high and the device can spray water to maintain the tunnel lining, the hand-tightened bolt 15 can be removed to turn the scraper 12 and the telescopic rod 11 180 degrees. When the device sprays water for maintenance, the scraper 12 no longer cleans the tunnel lining, thereby extending the service life of the device;

[0034] like Figure 4 As shown, a height adjustment mechanism 8 is installed on one side of the outer tube 4 and the telescopic tube 5, and the height adjustment mechanism 8 includes a threaded sleeve 801, a threaded rod 802 and a fixing plate 803. The threaded sleeve 801 is fixedly installed on one side of the telescopic tube 5, and the fixing plate 803 is fixedly installed on one side of the outer tube 4. The threaded rod 802 is adapted to the threaded sleeve 801, and one end of the threaded rod 802 passes through the fixing plate 803 and extends, and the threaded rod 802 is rotatably connected to the fixing plate 803;

[0035] By rotating the threaded rod 802 in the threaded sleeve 801 to move up and down, the height of the telescopic tube 5 relative to the outer tube 4 can be accurately controlled, thereby achieving fine adjustment of the height position of the spray head 7 and the scraper 12; this adjustment method ensures that the spray head 7 and the scraper 12 can adapt to tunnel linings of different heights, thereby improving the pertinence and effect of maintenance;

[0036] The water tank 1 is provided with a water inlet 20 at the top, a sealing plug 21 is fixedly installed on the water inlet 20, a filter frame 22 is also fixedly installed inside the water tank 1, and the filter frame 22 is located below the water inlet 20; the water tank 1 is also provided with an observation port 16 on the side plate, and a transparent plate 17 is fixedly installed on the observation port 16;

[0037] A plurality of rollers 18 are fixedly mounted on the bottom of the water storage tank 1, and a handle 23 is also fixedly mounted on the side panel.

[0038] The working principle of the utility model is as follows: first, the rotating threaded rod 802 is lifted and lowered in the threaded sleeve 801, so that the telescopic tube 5 can slide in the outer tube 4, thereby adjusting the height position of the spray head 7 and the scraper 12, so that the scraper 12 is against the tunnel lining. Once the height of the spray head 7 and the scraper 12 is adjusted in place, the pump 2 and the drive motor 144 start to work, and the pump 2 extracts the curing agent from the water tank 1, and transports it to the outer tube 4 through the connecting seat 19 and the elbow 3, and finally sprays it out from the spray head 7.

[0039] The driving motor 144 drives the crank shaft 145 to slide up and down in the movable opening 142; the movement of the crank shaft 145 is transmitted to the curved pipe 3 through the movable rod 143, so that the curved pipe 3 and the telescopic pipe 5, the spray head 7 and the scraper 12 connected thereto can swing left and right; the scraper 12 can remove dirt and attachments on the surface of the tunnel lining with the swinging movement.

[0040] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
