Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a maintenance and dust suppression vehicle based on the full section of the tunnel secondary lining concrete. Background Art

[0002] With the vigorous development of highway and railway tunnels, the number of long and large tunnels in my country is increasing. In tunnel engineering, the concrete of the secondary lining should be maintained in time after demoulding. If the maintenance is not timely, the moisture in the concrete will evaporate, resulting in dehydration, which will prevent the formed gel cement particles from being fully hydrated and converted into stable crystals. The cement particles lack sufficient adhesion, and flaky and powdery detachment will appear on the concrete surface. At the same time, if the moisture evaporates too early, the concrete will shrink and deform, and shrinkage cracks will appear, affecting the durability and integrity of the concrete. In addition, the tunnel contains a large amount of dust, which affects the air quality. In order to facilitate tunnel maintenance, various tunnel maintenance operation trolleys have emerged.

[0003] At present, the traditional secondary lining maintenance trolley cannot adjust the position of the nozzle according to the different specifications of tunnels when maintaining the tunnel, which leads to uneven water spraying and reduced maintenance and dust reduction effects. For this reason, we propose a maintenance and dust reduction vehicle based on the full section of the tunnel secondary lining concrete. Utility Model Content

[0004] The purpose of this utility model is to provide a maintenance and dust reduction vehicle based on the full section of the tunnel secondary lining concrete, so as to solve the problem raised in the above background technology that the current traditional secondary lining maintenance trolley cannot adjust the position of the nozzle according to tunnels of different specifications when maintaining the tunnel, thereby resulting in uneven water spraying and reduced maintenance and dust reduction effects.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a maintenance dust suppression vehicle based on the full section of the tunnel secondary lining concrete, comprising a vehicle body 1, a water tank 2, a water pump 3 and a dust suppression component 6 are respectively provided on the top of the vehicle body 1, the water inlet end of the water pump 3 is connected to the water inlet pipe 4, the water inlet pipe 4 is connected to the water tank 2, the water outlet end of the water pump 3 is connected to the first telescopic hose 5, a fixing plate 7 is installed on the top of the vehicle body 1 and on one side of the dust suppression component 6, two symmetrical first electric push rods 10 are installed on the outer side of the fixing plate 7, and a protective cover 8 is commonly installed on the telescopic ends of the two first electric push rods 10, the protective cover 8 is located outside the dust suppression component 6, and a dust sensor 9 is provided on the outer side of the protective cover 8;

[0023] The dust suppression assembly 6 includes a fixed seat 61 mounted on the top of the vehicle body 1, a motor 62 is installed at the bottom end of the fixed seat 61, a screw rod 63 is connected to the power drive end of the motor 62, the screw rod 63 and the fixed seat 61 are connected at the connection point through a bearing, the outside of the screw rod 63 is connected to a movable seat 64, the movable seat 64 is slidably connected to the inside of the fixed seat 61, sliders 65 are installed on both sides of the outside of the movable seat 64, and slide grooves 66 are opened on both sides of the inside of the fixed seat 61. The slider 65 is located inside the slide groove 66 and is a sliding connection structure. Two symmetrical mounting brackets 67 are installed on the top of the movable seat 64. The two mounting brackets 67 are connected to the fixed seat 61. The top of each of the fixing plates 7 passes through and extends to the top of the fixing seat 61, and a fixing frame 68 is installed. A shunt pipe 69 is installed on the outside of the fixing frame 68. One end of the first telescopic hose 5 passes through and extends to one side of the fixing plate 7 and is connected to the shunt pipe 69. Several groups of second telescopic hoses 610 are connected to the inside of the shunt pipe 69. One end of each second telescopic hose 610 is connected to an atomizing nozzle 611. A second electric push rod 612 is installed on the outside of the fixing frame 68 and at the position corresponding to the second telescopic hose 610. A mounting plate 613 is installed at the telescopic end of the second electric push rod 612, and the atomizing nozzle 611 is installed inside the mounting plate 613.

[0024] When dust reduction maintenance is required, the user first takes out the dust reduction assembly 6, and then moves several groups of atomizing nozzles 611 to a suitable height according to the needs of the staff. The user starts the motor 62, and the power drive end of the motor 62 drives the screw 63 to rotate. The movable seat 64 is located inside the fixed seat 61 and moves linearly through the setting of the slider 65 and the slide 66. The movable seat 64 drives the fixed frame 68 to adjust the height through the two mounting brackets 67. After moving to the appropriate height, the motor 62 stops operating, and then the position of each group of atomizing nozzles 611 is adjusted according to the specifications of the tunnel. The staff adjusts the position of each group of atomizing nozzles 611 through several groups of second motors. The movable push rod 612 drives the atomizing nozzle 611 connected to the mounting plate 613 to move. When the position of the atomizing nozzle 611 is adjusted, the staff starts the water pump 3. The water pump 3 draws water from the water tank 2 through the water inlet pipe 4, and then the water is transported to the diversion pipe 69 by the first telescopic hose 5. Finally, the water is sprayed from the mounting plate 613 connected by several groups of second telescopic hoses 610 for maintenance and dust reduction. It can evenly spray and maintain tunnels of different specifications. The first telescopic hose 5 and several groups of second telescopic hoses 610 are made of telescopic materials and do not affect the transportation of water. This device is easy to move, sprays water without dead angles, covers the entire area, and sprays water evenly.

[0025] The atomizing nozzle 611 is a device that can spray liquid into atomized form and evenly suspend it in the air. Its working principle is to squeeze the internal liquid into the nozzle through internal pressure. An iron sheet is placed inside the nozzle. The high-speed flowing liquid hits the iron sheet and rebounds to form atomized particles with a diameter of about 15-60 microns, which are then sprayed out through the nozzle outlet.

[0026] Example 2

[0027] like Figures 1 to 4 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that when the dust reduction component 6 is not in use, the user starts the first electric push rod 10, and the telescopic end of the first electric push rod 10 drives the protective cover 8 to move toward the fixed plate 7 until the protective cover 8 is located outside the dust reduction component 6. The dust reduction component 6 can be stored inside the protective cover 8 to prevent the atomizing nozzle 611 from clogging the water outlet when the dust is not in use; and when no maintenance is performed, when the dust sensor 9 senses that the dust state in the tunnel reaches a certain value, the first electric push rod 10 and the dust reduction component 6 are also started to perform dust reduction work on the tunnel, which greatly reduces the impact of dust in the tunnel on construction. This device can not only be used for tunnel maintenance but also for dust reduction work.
