Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel concrete lining construction, and specifically relates to an engineering vehicle for conveying concrete from one window to another on a second lining trolley. Background Art

[0002] With the rapid development of national transportation infrastructure projects, the amount of concrete construction in tunnels is increasing, and the demand for mechanization is getting higher and higher. In order to ensure the quality of the secondary lining concrete pouring construction, the construction requirements generally require the selection of a secondary lining trolley.

[0003] There is now a second lining trolley window-by-window pouring device, see the patent document with publication (announcement) number CN221096552U. After it is fixed on the second lining trolley, it is very convenient for concrete pouring construction, especially suitable for large trolleys used in wider tunnels, such as double-track tunnels and triple-track tunnels.

[0004] In a single-track tunnel, the trolley is not wide enough, and it is also necessary to avoid the air supply duct of the trolley. If it (the window-by-window casting device for the second lining trolley) is fixed on the second lining trolley, the posture adjustment of the pump pipe will be greatly restricted, and the discharge port of the pump pipe cannot reach certain local positions, which brings trouble to the concrete pouring construction. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to design a single-line tunnel trolley concrete placing vehicle to facilitate the posture adjustment of the pump pipe.

[0006] The technical solution of the utility model is specifically as follows:

[0007] A single-track tunnel trolley concrete placing vehicle comprises a single-track tunnel trolley, wherein a placing vehicle is arranged in a channel at the lower part of the single-track tunnel trolley; the placing vehicle comprises a vehicle body, wherein a traveling system is arranged at the lower part of the vehicle body; a casting system is arranged on the vehicle body, and the casting system comprises a placing boom and a pump pipe; the placing boom comprises a base slewing bearing, wherein a fixed part of the base slewing bearing is fixed to the vehicle body, and a rotating part of the base slewing bearing fixes the base, the base is connected to a first arm via a one-arm slewing bearing, the first arm is connected to a second arm via a two-arm slewing bearing, the second arm is connected to a third arm via a three-arm slewing bearing, and the third arm is connected to a fourth arm via a four-arm slewing bearing; and the pump pipe is laid along the placing boom.

[0008] The base and the first arm are hinged via an arm oil cylinder.

[0009] The base slewing bearing, the two-arm slewing bearing and the three-arm slewing bearing rotate in the horizontal plane, and the one-arm slewing bearing and the four-arm slewing bearing rotate in the vertical plane.

[0010] The pump pipe comprises a plurality of sections of straight pipes or curved pipes connected in series, and a plurality of pipe hoops for fixedly connecting with the material distributing arm are arranged on the outer wall of the pump pipe.

[0011] The farthest pipe in the pump pipe is a rubber tube.

[0012] The vehicle body is hinged to the supporting legs, and the vehicle body and the supporting legs are hinged via supporting oil cylinders.

[0013] Compared with the prior art, the technical effect of the utility model is that, in view of the shortcomings of existing products on the market, the utility model designs the material distribution car in the second lining trolley to be mobile. If the posture adjustment of the pump pipe is greatly restricted, it can be carried out by moving the material distribution car in the second lining trolley, which brings convenience to the concrete pouring construction.

Among them, the base swivel bearing 331, the two-arm swivel bearing 333, and the three-arm swivel bearing 334 rotate in the horizontal plane, and the one-arm swivel bearing 310 and the four-arm swivel bearing 335 rotate in the vertical plane, so that the postures of the material distribution boom are more diverse.

[0025] In order to adjust the included angle between the base 311 and the first arm 312 , the base 311 and the first arm 312 are hinged via an arm cylinder 332 .

[0026] like Figure 6 As shown, the pump pipe 400 is laid along the material distributing boom, and includes a plurality of straight pipes 421 or curved pipes 422 connected in series, and a plurality of pipe clamps 424 for fixed connection with the material distributing boom are provided on the outer wall thereof.

[0027] like Figure 6 As shown, in order to reduce the deadweight of the outer end, the farthest pipe in the pump tube 400 is a rubber tube 423.

[0028] like Figure 3-4 As shown, in order to facilitate support, the vehicle body 210 is hinged to the support leg 220 , and the vehicle body 210 and the support leg 220 are hinged via a support cylinder 221 .

[0029] like Figure 3-4 As shown, the driving component of the walking system 211 is the hydraulic system 260, and the control components of the walking system 211 are the power system 240 and the electrical system 250, wherein the walking system 211 includes two hydraulically driven tracks, and the hydraulic system 260 is driven by the power system 240 and the electrical system 250 to drive the track chassis of the walking system 211 to move forward or backward, and the forward, backward, left turn, right turn, rotation and other movements are realized through different combinations of the rotation of the tracks on both sides.

[0030] The power system 240 includes an engine 241, a fuel tank 242, and a central control panel 243. The electrical system 250 includes a switch button 262 and a remote control system 261.

Since this part is existing technology, it will not be repeated here.

[0031] Its working principle is:

[0032] S1. When working:

[0033] like Figure 1-2 , move the fabric cart 200 to a suitable position, extend the piston of the supporting cylinder 221, and adjust the supporting leg 220 to a supporting posture.

[0034] 1. Move the fabric cart 200 to a suitable position, extend the piston of the support cylinder 221, adjust the support leg 220 to a supporting position, and ensure that the support opening angle meets the requirements;

[0035] 2. After checking that the ground load meets the requirements, raise each leg so that the chassis is about 20cm off the ground;

[0036] 3. The feed port of the pump pipe 400 is connected to the discharge port of the concrete pump and supported and fixed securely;

[0037] 4. Use the remote control to operate the placing arm so that the discharge port of the pump pipe 400 reaches the designated pouring window position;

[0038] 5. The concrete pump pumps concrete through the pipeline to the pouring position. After pouring one place, the distribution arm is moved to the next pouring window through remote control. This operation completes the entire construction and pouring process in sequence. During adjustment, if it interferes with other components, it is completed by moving the distribution vehicle 200. During adjustment, the posture of the pump pipe 400 is adjusted synchronously with the distribution arm.

[0039] 6. After the material is placed, use the concrete pump to pump clean water to clean the pump pipe, and then operate the material placing boom to return to the parking position (such as Figure 3 ) and location;

[0040] 7. Remove the pump pipe connecting the pump truck and the material placing truck, and retract each leg in turn;

[0041] 8. Drive the fabric truck away from the construction site and park it in the parking lot until the next construction use.

[0042] Features of this application:

[0043] S1. The base slewing bearing 331 drives the base 311 to rotate 360° as a whole. The one-arm oil cylinder 332 is telescopic to drive the first arm 312 to perform a 0-90° lifting and lowering action. The two-arm slewing bearing 333 drives the second arm 313 to rotate 0-360°. The three-arm slewing bearing 334 drives the third arm 314 to rotate 0-360°. The four-arm slewing bearing 335 drives the fourth arm 315 to rotate -90-90°. Through the posture movements of each arm, the concrete discharge port reaches the window position that needs to be poured, enriching the posture and facilitating the realization of fixed-point positioning pouring.

[0044] S2. By moving the material distributing vehicle 200, it is more convenient to adjust the postures of the material distributing arm and the pump pipe 400.

[0045] S3. The front part of the robot arm is designed as a plate to reduce the front weight and provide a guarantee for the safety of the robot arm.

[0046] S4. The stability of pouring is increased by supporting the legs 220.
