Description

Technical Field

[0001] The invention relates to a special operation vehicle for emergency traffic maintenance, belonging to the technical field of vehicle engineering. Background Art

[0002] As an important infrastructure for the development of the national economy, highways have always played an important role. However, with the increase in highway operating mileage and the increase in the service life of the road surface, the amount of highway maintenance has also increased year by year. If the maintenance is not timely, the service quality and service level of the highway will decline. In serious cases, traffic accidents will occur and the service life of the highway will be shortened. Highway maintenance construction work is usually carried out without closing the entire road surface for traffic. Traffic flow and complex on-site working environment are likely to bring high risks to highway maintenance construction work. Since the construction work must occupy part of the lane road surface, it is easy to form a road traffic bottleneck, causing traffic congestion and congestion. Any negligence is very likely to cause road safety accidents.

[0003] In order to improve the efficiency of highway maintenance, the commonly used maintenance materials are mostly special materials, mainly high-alumina cement series, water glass series and phosphate cement series, etc., which have the advantages of fast coagulation and hardening and high early strength. It is precisely because the commonly used maintenance materials are fast-setting materials (for example, highways are usually required to be open to traffic within two hours), which makes the existing concrete pump trucks unusable. This is because it often takes a long time to transport the maintenance materials from the factory to the construction site after they are mixed evenly. If the maintenance materials are transported by concrete pump trucks, the materials may solidify before they can be repaired, which brings difficulties to the construction work.

[0004] Therefore, at present, when repairing roads, the commonly used method is to manually mix the repair materials on site, that is, at the repair site, the construction workers mix the repair materials evenly before use. However, when the repair materials are manually mixed on site, the dust in the on-site construction work area is too large, which will affect the environment on the same side, and when the repair materials are mixed, the passing vehicles around the construction area are also likely to cause danger to the construction workers. In addition, according to the applicant’s understanding, there are similar problems that need to be solved at the construction sites of field repairs of high-speed railways, rapid repairs of intercity railways, urban monorails, etc., sponge city permeable concrete pavement construction, municipal roads and bridges, local ordinary highways and bridges, rapid repairs in the field of construction engineering reinforcement, and rapid repairs of hydraulic structures and dams. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an emergency traffic maintenance vehicle which can not only avoid dust pollution at the maintenance site but also improve the road maintenance efficiency.

[0006] In order to solve the above technical problems, the technical solution proposed in the present invention is: an emergency traffic maintenance special operation vehicle, comprising a chassis; a liquid storage unit, a material storage unit, a conveying unit and a stirring unit are installed on the frame of the chassis, and the material storage unit, the conveying unit and the stirring unit are all sealed, wherein the stirring unit is located at the rear end of the chassis; the material discharge port of the material storage unit is connected to the material feed port of the conveying unit, the material discharge port of the conveying unit is connected to the material feed port of the stirring unit, and the liquid outlet of the liquid storage unit is connected to the liquid inlet of the stirring unit.

[0007] First of all, it should be noted that the present invention defines some technical features by "front" and "rear", where "front" refers to the direction toward the front of the vehicle (driving cabin), and "rear" refers to the direction toward the rear of the vehicle. In addition, longitudinal refers to the direction along the length of the vehicle body, that is, the front-to-back direction.

[0008] In the field of emergency traffic maintenance, because the commonly used maintenance materials are fast-setting materials, which can usually solidify within one or two hours, the present invention uses a sealed special operation vehicle to prepare maintenance materials on site. Compared with the maintenance materials prepared by manual mixing on the roadside in the prior art, dust pollution is avoided and operation efficiency is improved. The present invention is not only suitable for the rapid repair of highways and cross-river and sea bridges, but also for the field repair of high-speed railways, the rapid repair of intercity railways, urban monorail trains, etc., municipal roads and bridges, sponge city permeable concrete pavement construction, local ordinary highways and bridges, rapid repairs in the field of construction engineering reinforcement, and rapid repairs of hydraulic structures and dams. It can even be applied to the rapid repair of wind power towers in the field of new energy wind power.

[0009] In order to meet the requirements of transportation safety, the liquid storage unit, material storage unit, conveying unit and stirring unit in the present invention cannot exceed the chassis position of the work vehicle; at the same time, the height of existing special work vehicles has corresponding national standards, and its chassis height and overall height must comply with relevant regulations, such as the height limit of the whole vehicle is 4.5 meters. The applicant found in practice that, restricted by the position and height of the chassis, the discharge port of the stirring unit is relatively low, and only a trolley can be used to receive the materials and transport the maintenance materials to the construction site, and it is impossible to use efficient transportation tools such as drag pumps. There are at least two reasons for this: 1) The drag pump also has corresponding standards, and the height of its feed port exceeds the standard height of the chassis of the work vehicle, so it cannot enter under the chassis to receive the materials; 2) The diameter of the discharge port of the stirring unit on the market often exceeds 50cm, so it is impossible to directly use a conduit to transfer the materials, and it is necessary to connect the conduit through a funnel-shaped transfer device, which is equivalent to further reducing the height of the discharge port of the stirring unit, which is much lower than the height of the feed port of the drag pump.

[0010] In view of the above problems, the applicant has made further improvements to the above technical solution, and the improvements are as follows: a mounting frame and at least two longitudinally arranged tracks are provided on the chassis frame, the liquid storage unit, material storage unit, conveying unit and stirring unit are all arranged on the mounting frame, the bottom of the mounting frame is provided with a plurality of running wheels matching the tracks, and the chassis frame is provided with a limiting device for fixing the running wheels; the frame is also provided with a hydraulic drive unit for driving the mounting frame to reciprocate along the track, so that the discharge port of the stirring unit has a first position located directly above the chassis and a second position located at the rear side of the chassis. When discharging the material, the mounting frame can be driven to move the discharge port of the stirring unit to the rear side of the chassis, so that the discharge port of the stirring unit will exceed the height of the drag pump, so that the drag pump can be used directly to receive the material. The drag pump not only has a larger capacity, but also has a stirring function, which may prevent the repair material from solidifying. Compared with the use of a trolley, the construction efficiency and quality are improved. In addition, moving the discharge port of the stirring unit to the rear side of the chassis has another beneficial effect, that is, when cleaning the stirring unit, the sewage discharged from the stirring unit will not pollute and corrode the chassis, which is equivalent to increasing the life of the entire vehicle.

[0011] A further improvement of the above technical solution is: the track is provided with a downward curved section that can just allow the running wheel to sink into, the number and position of the downward curved sections correspond to the running wheels one by one, and when the running wheels sink into the corresponding downward curved sections, the hydraulic drive unit, the liquid storage unit, the material storage unit, the conveying unit and the stirring unit are all located directly above the chassis. In this way, during transportation, the running wheels sink into the corresponding downward curved sections, firstly, the mounting frame is relatively stable, and secondly, it prevents the driver from being in danger of rushing forward during braking. When the mounting frame moves, the hydraulic drive unit can drive the mounting frame to move horizontally through a horizontally arranged hydraulic cylinder, and drive the running wheels of the mounting frame to move in and out of the downward curved sections through an inclined hydraulic cylinder. This is a prior art and will not be described in detail.

[0012] In order to further improve the stability of the mixing unit during operation, the chassis is provided with support legs driven by a hydraulic drive unit. The support legs are prior art and can be set with reference to the support legs of a pump truck. However, conventional special-purpose work vehicles usually do not have support legs because they do not have hydraulic drive units. The present invention drives the mounting frame to move by adding a hydraulic drive unit, and the hydraulic drive unit is used to drive the support legs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION Embodiment 1

[0018] The emergency traffic maintenance special operation vehicle of this embodiment is as follows Figure 1 As shown, the chassis 1 (such as Figure 2 As shown in the figure, a liquid storage unit 3, a material storage unit 5, a conveying unit 11 and a stirring unit 6 are installed on the frame of the chassis 1, and the liquid storage unit 3, the material storage unit 5, the conveying unit 11 and the stirring unit 6 are all sealed, wherein the stirring unit 6 is located at the rear end of the chassis 1.

[0019] The material outlet of the material storage unit 5 is connected to the material inlet of the conveying unit 11 , the material outlet of the conveying unit 11 is connected to the material inlet of the stirring unit 6 , and the liquid outlet of the liquid storage unit 3 is connected to the liquid inlet of the stirring unit 6 .

[0020] In this embodiment, the stirring unit 6 can adopt a vertical or horizontal stirrer, and the conveying unit 11 adopts a conveyor belt. Of course, other existing conveying devices such as augers can also be used. The materials in the storage unit 5 generally adopt fast-setting materials, such as high-alumina cement series, water glass series and phosphate cement series, and corresponding additives are added. When in use, the storage unit 5 discharges the material, and the material is sent into the stirring unit 6 through the conveying unit 11. At the same time, the liquid in the liquid storage unit 3 also enters the stirring unit 6, and the stirring unit 6 stirs it evenly before discharging the material. The above whole process can be adjusted and controlled by the control unit 4. The control process is a prior art and will not be repeated here. This embodiment adopts a sealing setting to prepare maintenance materials on site, avoid dust pollution, and improve work efficiency.

[0021] The present embodiment may also be improved as follows: 1) a liquid meter 7 is provided at the liquid inlet of the stirring unit 6, and a material meter 8 is provided at the material inlet of the stirring unit, so that the proportion and quantity of the materials can be accurately controlled.

[0022] 2) A power generation unit 2 is also installed on the frame of the chassis 1, and the power generation unit 2 provides power for the liquid storage unit, the material storage unit, the conveying unit and the stirring unit.

[0023] 3) The stirring unit 6 is provided with an artificial feeding port 9 to facilitate the adjustment of the material. Embodiment 2

[0024] This embodiment is a further improvement on the first embodiment, and its improvements are as follows: Figure 3 As shown, the chassis 1 is provided with a mounting frame (not shown) and at least two longitudinally arranged tracks 13, the liquid storage unit, material storage unit, conveying unit and stirring unit are all arranged on the mounting frame, and the bottom of the mounting frame is provided with a plurality of running wheels 12 matching the tracks 13. The running wheels 12 are preferably arranged in pairs, such as Figure 3 As shown, a pair of running wheels 12 are disposed at both ends of the wheel axle 14, and the running wheels 12 can be matched with the track 13 in a manner similar to train wheels.

[0025] The chassis frame is provided with a limit device for fixing the running wheel 12, and the limit device can be a limit pin, etc. The chassis 1 frame is also provided with a hydraulic drive unit (not shown in the figure, and a cylinder, etc.) for driving the mounting frame to reciprocate along the track, so that the discharge port of the mixing unit 6 has a first position located directly above the chassis 1 and a second position located at the rear side of the chassis 1.

[0026] When the working vehicle is driving, the discharge port of the mixing unit 6 is located in the first position, the limiting device fixes the traveling wheels, and the mixing unit 6 does not work; when the mixing unit 6 is working, its discharge port is located in the second position. At this time, the limiting device also fixes the traveling wheels, so that the discharge port avoids the position of the frame, making it convenient for higher devices such as towed pumps to receive materials.

[0027] This embodiment can also be improved as follows: 1) Figure 3 As shown, the track 13 is provided with a downward curved section 15 into which the travel wheel 12 can just sink, and the number and position of the downward curved sections 15 correspond one-to-one to the travel wheel 12. When the travel wheel 12 sinks into the corresponding downward curved section 15, the hydraulic drive unit, the liquid storage unit, the material storage unit, the conveying unit and the stirring unit are all located directly above the chassis 1. At this time, the discharge port of the stirring unit is located at the first position, so that during transportation, the downward curved section 15 can prevent the mounting frame from rushing forward due to braking, thereby ensuring the safety of the cab.

[0028] 2) If Figure 2 As shown, the longitudinal beam 16 of the chassis 1 frame also serves as a track, that is, the running wheels are engaged with the longitudinal beam of the chassis frame.

[0029] 3) If Figure 1 As shown, the chassis 1 is provided with supporting legs 10 driven by a hydraulic drive unit.

[0030] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementation modes.
