Description

Technical Field

[0001] The present invention relates to the technical field of tunnel maintenance equipment, and particularly to a maintenance equipment for tunnel linings of road bridges. Background Art

[0002] With the booming development of infrastructure construction, the number of infrastructure buildings is increasing day by day. During the construction of some buildings, the quality requirements are very strict. For example, the structural concrete needs to be cured for more than seven days after pouring. Secondary lining is a relatively common curing method. If the secondary lining is not cured in time, cracks will appear on the concrete surface, causing serious consequences.

[0003] In actual projects, the current maintenance equipment is basically for small-scale mobile operations, which can only operate locally and then complete the maintenance in a splicing manner. Moreover, during maintenance, it cannot fit the inner wall of the tunnel, thereby reducing the maintenance effect, and the maintenance construction stage is time-consuming and laborious. Summary of the Invention

[0004] The main inventive concept of the present invention is as follows: The spray opening degree can be adjusted according to the size of the tunnel arch surface, that is, after passing through once, the secondary lining of the entire arch surface can be spray-cured, without the need for the existing equipment to perform local maintenance and then frequently move the maintenance equipment, thereby improving the maintenance efficiency.

[0005] Therefore, the present invention provides a maintenance equipment for tunnel linings of road bridges, including a vehicle body with traveling wheels. A driving mechanism for driving the traveling wheels to travel is provided on the vehicle body. A water storage tank is provided on the vehicle body. A pressurizing mechanism is provided on the water storage tank. The pressurizing mechanism is communicated with a spray mechanism. An adjusting mechanism is also provided on the vehicle body. The spray mechanism is arranged on the adjusting mechanism, and a linkage deformation mechanism is further included between the water storage tank and the adjusting mechanism.

[0006] By adopting the above technical solutions: Driven by the driving mechanism, the traveling wheels can travel, thereby driving the entire vehicle body to move. The water storage tank on the vehicle body is used to store the spray water. The water can be pressurized through the pressurizing mechanism and then sprayed onto the secondary lining of the tunnel inner wall through the spray mechanism to complete the maintenance. By setting the adjusting mechanism, the spray range of the spray mechanism can be adjusted to adapt to the tunnel secondary lining surface. Through the linkage deformation mechanism, the shape of the spray mechanism can be changed in a linkage manner to make it more fit the tunnel secondary lining surface, so as to better complete the spray maintenance. This technical solution can more accurately and conveniently complete the maintenance by traveling from one side of the tunnel to the other side, improving the maintenance efficiency.

[0007] Preferably, there are four running wheels divided into two groups, each group of running wheels is connected to the gearbox through a half-shaft, and the two gearboxes are also connected through a transmission shaft, and one of the gearboxes is drivingly connected to a driving motor arranged on the vehicle body.

[0008] By adopting the above technical solution: the gearbox is driven by the driving motor, and the two gearboxes are transmitted through the transmission shaft, which can drive the four walking wheels to rotate synchronously, thereby facilitating the movement of the vehicle body for spraying maintenance.

[0009] Preferably, the pressurizing mechanism comprises a pressurizing pump disposed on the water tank, a water inlet pipe of the pressurizing pump is connected to the bottom of the water tank via the water inlet pipe, and a water outlet end of the pressurizing pump is connected to the spray mechanism via a connecting pipe.

[0010] By adopting the above technical solution: the water inside the water tank is pressurized by a pressure pump and sent to the spray mechanism through a connecting pipe, and sprayed by the spray mechanism to form water mist for spraying and maintaining the secondary lining of the tunnel.

[0011] Preferably, the adjustment mechanism includes a height adjustment component arranged on the vehicle body and a diameter expansion component arranged on the water tank, and also includes a cooperative power component that drives the height adjustment component and the diameter expansion component to move synchronously.

[0012] By adopting the above technical solution: the height adjustment component can be adjusted according to the overall height of the tunnel, and the diameter expansion component can expand the spray mechanism outward to make it fit the inner wall of the tunnel better, thereby achieving a better spraying effect. Driven by the coordinated power component, the height adjustment component and the diameter expansion component can move synchronously to adjust to a posture that is as compatible as possible with the inner wall of the tunnel.

[0013] Preferably, the height adjustment assembly includes a telescopic part arranged on the vehicle body, a hinge portion is provided on the top of the telescopic part, an elastic rod is hinged at the hinge portion, the elastic rod includes an oblique rod portion and a vertical rod portion, the upper end of the oblique rod portion is hinged at the hinge portion, the vertical rod portion is connected to the lower end of the oblique rod portion, and the side of the water tank also has a limiting plate for limiting the bottom end of the vertical rod portion.

[0014] By adopting the above technical solution: the setting of the telescopic part makes the spray height adjustable, and by setting the elastic rod, it can drive the spray mechanism to deform, so that the spray position is more closely fitted to the inner wall of the tunnel, and the inclined rod part and the vertical rod part are both elastic, so they are deformed under the action of external force to change the spray posture, and by setting the limit plate, the bottom end of the vertical rod part can be supported to prevent it from sliding onto the concrete surface at the bottom, and at the same time, a reaction force is provided for the outward expansion and deformation of the inclined rod part.

[0015] Preferably, the telescopic member includes a cavity column fixed to the vehicle body. A support sleeve is slidably sleeved on the upper part of the cavity column. A spring is provided between the support sleeve and the cavity column. The hinged part is arranged at the top of the support sleeve.

[0016] By adopting the above technical solution: The support sleeve can slide up and down relative to the cavity column, so as to facilitate changing the height and being applicable to different tunnels. When the support sleeve slides down, the overall spraying height can be reduced. When the pulling effect is lost, under the action of the spring, the support sleeve can reset, thus facilitating the adjustment of the overall spraying height.

[0017] Preferably, the hinged part includes two hinged pieces arranged at the top of the support sleeve. An arc-shaped chute is provided on the hinged piece. A hinged shaft is provided at the top end of the inclined rod part. The hinged shaft slides in the arc-shaped chute.

[0018] By adopting the above technical solution: Through the hinged manner of the arc-shaped chute and the hinged shaft, the inclined rod part can rotate relatively.

[0019] Preferably, the diameter-expanding assembly includes two L-shaped rods slidably arranged on the water storage tank through a sliding assembly. A retaining sleeve is provided at one end of the L-shaped rod. The retaining sleeve is sleeved on the vertical rod part. A rack is provided at the other end of the L-shaped rod. The racks of the two L-shaped rods face each other. A limiting convex strip is provided on the vertical rod part. A limiting block is provided in the retaining sleeve. The limiting convex strip is slidably connected with the limiting block.

[0020] By adopting the above technical solution: By arranging the sliding assembly, the two L-shaped rods can be limited, so that the two L-shaped rods can move relatively parallel, and thus the two L-shaped rods can be relatively contracted and pushed outwards. A retaining sleeve is arranged at the end of the L-shaped rod. The retaining sleeve is sleeved on the vertical rod part, and the vertical rod part can be relatively fixed, so that the vertical rod part can slide up and down along the retaining sleeve. When the support sleeve moves downwards, due to the limiting effect of the retaining sleeve and the supporting effect of the limiting plate, the inclined rod part bends outwards as much as possible to be close to the secondary lining of the tunnel, driving the spraying mechanism to perform spraying and enclosure. By arranging the cooperation of the limiting block and the limiting convex strip, the limiting of the vertical rod part is further ensured to prevent it from sliding out of the limiting sleeve.

[0021] Preferably, the sliding assembly includes a limiting sliding sleeve arranged on the side wall of the water storage tank. The L-shaped rod is slidably arranged inside the limiting sliding sleeve.

[0022] By adopting the above technical solution: The L-shaped rod can be limited through the limiting sliding sleeve, so that the two L-shaped rods can move relatively parallel.

The driving gear is fixedly connected to the rotating shaft of the servo motor. It further includes a pulling member for driving the support sleeve to move downward along the cavity column. The pulling member includes a winding drum arranged on the rotating shaft. One end of a steel wire rope is fixed on the winding drum, and the other end of the steel wire rope is fixed on the support sleeve.

[0024] By adopting the above technical solution: The driving gear is driven by the servo motor. After the driving gear rotates, it can drive the L-shaped rods on its upper and lower sides to move relatively through the racks, so as to push the vertical rod portions outward. At the same time, the pulling member can drive the support sleeve to move downward, adjusting the spraying height and expanding the spraying range outward, so as to fit the tunnel inner wall as much as possible, and the lining maintenance of the entire tunnel side wall can be completed in one spraying.

[0025] Preferably, the spraying mechanism includes a spraying flexible belt arranged on the two elastic rods and the top of the support sleeve. The spraying flexible belt is communicated with the connecting pipe.

[0026] By adopting the above technical solution: The connecting pipe can be a telescopic flexible hose. After the water pressurized by the pressure pump is sent to the spraying flexible belt, the spraying flexible belt is provided with fine holes, and water mist is formed after spraying through the fine holes, so as to complete the maintenance of the tunnel secondary lining.

[0027] Preferably, the linkage deformation mechanism includes a column arranged on the water storage tank. The upper end of the column is provided with a top contact part with an arc surface.

[0028] By adopting the above technical solution: When the support sleeve moves downward, it compresses the inclined rod portion. Through the column and the top contact part, the inclined rod portion can be pushed outward to make it as arc-shaped as possible.

[0029] Preferably, the linkage deformation mechanism includes a holding column arranged on the water storage tank. A top contact rod is arranged in the holding column. One end of the top contact rod close to the inclined rod portion is provided with a top contact part, and the other end of the top contact rod is provided with a driven block with an inclined surface. The support sleeve is provided with a touch block with an inclined surface. When the touch block moves downward, it pushes the driven block to move outward, and the top contact part on the top contact rod contacts the inclined rod portion to push the inclined rod portion outward.

[0030] By adopting the above technical solution: When the support sleeve moves downward, the touch block presses on the driven block, causing the driven block to move outward, thereby driving the holding rod to move outward. The top contact part on the holding rod can push the inclined rod portion outward to make it as arc-shaped as possible, so as to fit the tunnel inner wall as much as possible, further improving the spraying and maintenance effect.

[0031] The working principle and beneficial effects of the present invention are as follows: 1. Driven by the driving mechanism, the traveling wheels can move, thereby driving the entire vehicle body to move. The water storage tank on the vehicle body is used to store the spraying water. The water can be pressurized by the pressurizing mechanism and then sprayed onto the secondary lining of the tunnel inner wall through the spraying mechanism to complete the maintenance. By setting the adjusting mechanism, the spraying range of the spraying mechanism can be adjusted to adapt to the secondary lining surface of the tunnel. Through the linkage deformation mechanism, the shape of the spraying mechanism can be changed in a linkage manner to make it more conform to the secondary lining surface of the tunnel, so as to better complete the spraying maintenance. By walking from one side of the tunnel to the other side, this technical solution can complete the maintenance more accurately and conveniently, improving the maintenance efficiency.

[0032] 2. The height adjustment component in the present invention can be adjusted according to the overall height of the tunnel. The diameter expansion component can expand the spraying mechanism outwards to make it more conform to the tunnel inner wall, so as to achieve a better spraying effect. Driven by the cooperative power component, the height adjustment component and the diameter expansion component can act synchronously to adjust to a posture that is as suitable as possible for the tunnel inner wall.

[0033] 3. The setting of the telescopic member enables the spraying height to be adjusted. By setting the elastic rod, it can drive the spraying mechanism to deform, so that the spraying position is more conform to the tunnel inner wall. Both the inclined rod part and the vertical rod part are elastic, so they deform under the action of external force to change the spraying posture. By setting the limiting plate, the bottom end of the vertical rod part can be supported to prevent it from sliding onto the concrete surface at the bottom, and at the same time, it also provides the reaction force for the outward expansion and deformation of the inclined rod part.

[0034] 4. By setting the sliding component, the two L-shaped rods can be limited, so that the two L-shaped rods can move relatively parallel, and thus the two L-shaped rods can be relatively contracted and pushed outwards. A holding sleeve is arranged at the end of the L-shaped rod, and the holding sleeve is sleeved on the vertical rod part, which can relatively fix the vertical rod part, so that the vertical rod part can slide up and down along the holding sleeve. When the support sleeve moves downwards, due to the limiting effect of the holding sleeve and the supporting effect of the limiting plate, the inclined rod part bends outwards as much as possible to be close to the secondary lining of the tunnel, driving the spraying mechanism to carry out spraying and enclosure. Through the cooperation of the limiting block and the limiting rib, the limiting of the vertical rod part is further ensured to prevent it from slipping out of the limiting sleeve.

[0035] 5. When the support sleeve moves downwards, the trigger block hijacks the driven block, causing the driven block to move outwards, thereby driving the holding rod to move outwards. The abutting part on the holding rod can push the inclined rod part outwards to make it as arc-shaped as possible, so as to be as close to the tunnel inner wall as possible, further improving the spraying maintenance effect.

The water tank 300 on the vehicle body 100 is used to store spray water.

By setting the adjustment mechanism 600, the spraying range of the spraying mechanism 500 can be adjusted to adapt to the secondary lining surface of the tunnel. The shape of the spraying mechanism 500 can be linked to the linkage deformation mechanism 700 to make it more fit the secondary lining surface of the tunnel, so as to better complete the spraying maintenance. The technical solution can complete the spraying maintenance more accurately and conveniently by walking from one side of the tunnel to the other side, thereby improving the maintenance efficiency.

[0043] Reference Figures 1 - 3 In this embodiment, four traveling wheels 110 are provided, which are divided into two groups. Each group of traveling wheels 110 is connected to a gearbox 220 through a half shaft 210. The two gearboxes 220 are also connected through a transmission shaft 230. One of the gearboxes 220 is drivingly connected to a driving motor 240 provided on the vehicle body 100. The transmission motor 240 drives the gearbox 220, and the two gearboxes 220 are driven through the transmission shaft 230, which can drive the four traveling wheels 110 to rotate synchronously, thereby facilitating the vehicle body 100 to travel for spraying maintenance.

[0044] Referring to Figures 1 - 3 , in order to be able to pressurize water, a pressurizing mechanism 400 is provided in this embodiment. It includes a pressure pump 410 arranged on the water storage tank 300. The water inlet pipe 420 of the pressure pump 410 is connected to the bottom of the water storage tank 300 through the water inlet pipe 420. The water outlet end of the pressure pump 410 is connected to the spraying mechanism 500 through a connecting pipe 430. The water inside the water storage tank 300 is pressurized by the pressure pump 410 and then sent to the spraying mechanism 500 through the connecting pipe 430, and is sprayed by the spraying mechanism 500 to form a water mist for spraying and curing the secondary lining of the tunnel.

[0045] Referring to Figures 1 - 3 , in order to be able to adjust the spraying range and adapt to the shape of the tunnel, the adjusting mechanism 600 in this embodiment includes a height adjusting component arranged on the vehicle body 100 and a diameter expanding component arranged on the water storage tank 300, and also includes a cooperative power component for driving the height adjusting component and the diameter expanding component to act synchronously; the height adjusting component can be adjusted according to the overall height of the tunnel, and the diameter expanding component can expand the spraying mechanism 500 outwards so that it can better fit the inner wall of the tunnel, thereby achieving a better spraying effect. Driven by the cooperative power component, the height adjusting component and the diameter expanding component can act synchronously to adjust to a posture that is as suitable as possible for the inner wall of the tunnel.

[0046] Referring to Figures 3 - 4 , specifically, the height adjusting component includes a telescopic member arranged on the vehicle body 100. The top of the telescopic member is provided with a hinge portion, and an elastic rod is hinged at the hinge portion.

The upper end of the inclined rod portion 611 is hinged at the hinge portion, and the vertical rod portion 612 is connected to the lower end of the inclined rod portion 611. A limiting plate 613 for limiting the bottom end of the vertical rod portion 612 is also provided on the side of the water storage tank 300. The setting of the telescopic member enables the spraying height to be adjusted. By setting the elastic rod, it can drive the spraying mechanism 500 to deform, so that the spraying position is more suitable for the inner wall of the tunnel. Both the inclined rod portion 611 and the vertical rod portion 612 are elastic, so they deform under the action of an external force to change the spraying posture. By setting the limiting plate 613, the bottom end of the vertical rod portion 612 can be supported to prevent it from sliding onto the concrete surface at the bottom, and at the same time, it also provides a reaction force for the outward expansion and deformation of the inclined rod portion 611.

After the driving gear 631 rotates, it can drive the L-shaped rods 621 on its upper and lower sides to move relatively through the racks 623, so as to push the vertical rod part 612 outwards. At the same time, the pulling member can drive the support sleeve 615 to move downward, adjusting the spraying height and expanding the spraying range outwards, so as to fit the tunnel inner wall as much as possible, and the lining maintenance of the entire tunnel side wall can be completed in one spraying.

The shape of the spraying mechanism 500 can be linked to change through the linkage deformation mechanism 700 to make it more fit the secondary lining surface of the tunnel, so as to better complete the spraying maintenance. The technical solution can complete the maintenance more accurately and conveniently by walking from one side of the tunnel to the other side, thereby improving the maintenance efficiency.

[0058] On the basis of this basic technical solution, the rest is the same as Example 1, and the difference from Example 1 is as follows: in order to make the deformation amplitude of the inclined rod portion 611 larger and to be able to fit more closely to the secondary lining of the inner wall of the tunnel, the linkage deformation mechanism 700 in this embodiment includes a retaining column 730 arranged on the water tank 300, and a top connecting rod 731 is passed through the retaining column 730, and a top connecting portion 720 is provided at one end of the top connecting rod 731 close to the inclined rod portion 611, and a driven block 732 with an inclined surface is provided at the other end of the top connecting rod 731, and a trigger block 733 with an inclined surface is provided on the support sleeve 615. When the trigger block 733 moves downward, the driven block 732 is pushed to move outward, and the top connecting portion 720 is connected to the inclined rod portion 611 to push the inclined rod portion 611 outward.

[0059] When the support sleeve 615 moves downward under the pulling of the steel wire rope 634, the trigger block 733 hijacks the driven block 732, causing the driven block 732 to move outward, thereby driving the holding rod to move outward. The abutting portion 720 on the holding rod can push the inclined rod portion 611 outward, making it as arc-shaped as possible, so as to fit the tunnel inner wall as much as possible, further improving the spray curing effect.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
