Description

Technical Field

[0001] The utility model relates to tunnel construction equipment, in particular to filling layer concrete finishing equipment. Background Art

[0002] In the construction of the tunnel invert filling layer, there are high requirements for the surface forming of the filling concrete, and the demand for the filling layer concrete finishing equipment is becoming more and more widespread. In the existing double-track tunnel solution, the filling finishing device is mainly installed on the trestle, and some construction is divided into left and right sections according to the center ditch, and some finishing devices are installed on the template. The finishing device installed on the trestle is difficult to solve the impact of vehicles passing on the trestle on the finishing. The finishing device installed on the template relies on the left and right inverted arch templates for positioning, which is difficult to position, and the walking power is on both sides, which affects the installation and use of the inverted arch template. The left and right walking power synchronization is insufficient, the finishing device has a high walking failure rate, and the finishing device is limited by space. The overall rigidity is insufficient and easy to deform. In addition, the center ditch template, inverted arch template, side ditch template, etc. will inevitably have position errors during installation, including horizontal position errors and height position errors. The height positions of the templates on both sides may be different, but the original design height is required to be cast during construction.

[0003] The existing plastering device installed on the template has a track position welded and fixed, which is difficult to adjust after installation. At the same time, it will deform with the deformation of the template, causing the plastering machine to run off the track and the plastering portion to deviate from the designed position horizontally or vertically. In addition, there is generally no upper track design, resulting in accumulated concrete on the track. The plastering machine will fluctuate up and down when moving forward, causing the height of the plastering portion to deviate from the designed value. Utility Model Content

[0040] Embodiment 1:

[0041] like Figures 1 to 7 , Figures 9 to 11 , Fig.15 and Fig.17 As shown, the filling layer concrete finishing equipment of this embodiment includes a finishing trolley 1, a transverse adjustment seat 3 arranged on the left and right sides of the filling layer template 9, and a longitudinal track assembly 4 arranged on the transverse adjustment seat 3. The finishing trolley 1 is arranged on the longitudinal track assembly 4 through the running wheel 11, and the finishing trolley 1 is provided with a finishing assembly 2. Among them, the longitudinal direction is the tunneling direction or the length direction of the tunnel, the transverse direction is the width direction of the tunnel, and the vertical direction is the height direction.

[0042] The filling layer concrete finishing equipment of this embodiment, during finishing construction, adjusts the lateral position of the longitudinal track assembly 4 through the lateral adjustment seat 3. After adjustment, Fig.17 As shown, the plastering trolley 1 moves along the longitudinal track assembly 4, and the plastering assembly 2 plasters the concrete of the middle filling layer of the tunnel. In the filling layer concrete plastering equipment of this embodiment, the plastering assembly 2 moves along the templates 9 on the left and right sides of the filling layer, so that the plastering assembly 2 is not related to the trestle, and will not be affected by the deformation of the trestle's own weight, the passage of heavy-loaded vehicles on the trestle during plastering, etc., to ensure that the position of the plastering assembly 2 will not deviate from the elevation, and the plastering effect is good; by setting the transverse adjustment seat 3, the transverse position of the longitudinal track assembly 4 can be adjusted, even if the templates 9 on both sides have installation position errors, processing and manufacturing errors or load deformation, the position of the longitudinal track assembly 4 can be adjusted, so that the plastering trolley 1 will not rush out of the longitudinal track assembly 4, and the operation is stable and the adaptability is strong.

[0043] Preferably, in this embodiment, the plastering trolley 1 is further provided with a travel drive 12 connected to the travel wheel 11, which has a simple and reliable structure and allows the plastering trolley 1 to run smoothly. The travel drive 12 may be, for example, an electric motor or a hydraulic motor.

[0044] Furthermore, if Figure 5 As shown, in this embodiment, the longitudinal track assembly 4 includes a track seat 41 arranged on the transverse adjustment seat 3, and an upper track 42 and a lower track 43 arranged relatively on the track seat 41, and the running wheel 11 is arranged between the upper track 42 and the lower track 43. During the plastering construction, concrete and other debris are often piled up on the lower track 43, and the running wheel 11 of the plastering trolley 1 will be lifted when it runs over. By setting the upper track 42, the lifted running wheel 11 will conflict with the upper track 42, and then react to the concrete on the lower track 43, squeezing the concrete out of the track, reducing the up and down fluctuation amplitude of the plastering trolley 1. When the running wheel 11 is lifted, the upper track 42 can also play a role of limiting and guiding to prevent the running wheel 11 from deviating, so that the plastering stability is high and the plastering effect is better.

[0045] Furthermore, in this embodiment, the longitudinal track assembly 4 also includes a first vertical adjustment seat 44 (the first vertical adjustment seat 44 can be adjustably fixed to the track seat 41 by means of vertical waist-shaped holes and bolts) and a first adjustment screw 45, the upper track 42 is arranged on the first vertical adjustment seat 44, and the first adjustment screw 45 is connected to the first vertical adjustment seat 44. The first adjustment screw 45 is rotated to drive the first vertical adjustment seat 44 to rise and fall, and the position of the upper track 42 in the vertical direction can be adjusted, so as to cope with concrete accumulation of different thicknesses on the lower track 43, and prevent the walking wheel 11 from being stuck between the upper track 42 and the lower track 43 due to thick concrete accumulation, and the adaptability is stronger.

[0046] Furthermore, in this embodiment, the upper rail 42 and the lower rail 43 are both V-shaped, and the running wheel 11 is circumferentially provided with grooves that can cooperate with the upper rail 42 and the lower rail 43. The V-shaped rail cooperates with the groove, which can play a good role in limiting and guiding, and prevents the running wheel 11 from deflecting, and the structure is simple and effective.

[0047] Furthermore, in this embodiment, the plastering assembly 2 includes a first plastering roller 21 provided on the plastering trolley 1 and a rotating drive member 211 connected to the first plastering roller 21. When plastering, the rotating drive member 211 drives the first plastering roller 21 to rotate to plaster, and the first plastering roller 21 can quickly complete the plastering work of a large area with high plastering efficiency. Among them, the rotating drive member 211 can be, for example, an electric motor or a hydraulic motor, which drives the first plastering roller 21 to rotate through a transmission method such as a sprocket chain, a gear set, etc.

[0048] Furthermore, in this embodiment, the plastering assembly 2 further includes a second vertical adjustment seat 24 and a second adjustment screw 25 provided on the plastering trolley 1, the first plastering roller 21 is provided on the second vertical adjustment seat 24, and the second adjustment screw 25 is connected to the second vertical adjustment seat 24. The second adjustment screw 25 is rotated to drive the second vertical adjustment seat 24 to rise and fall, and the position of the first plastering roller 21 in the vertical direction can be adjusted, so that the first plastering roller 21 can adapt to the construction of filling surfaces with different elevations and eliminate the height error caused by processing, manufacturing and assembly, thereby ensuring the accurate construction position of the first plastering roller 21.

[0049] Preferably, if Figure 5 As shown, in this embodiment, a guide assembly 27 is further provided between the second vertical adjustment seat 24 and the plastering trolley 1. By providing the guide assembly 27, it is possible to prevent the first plastering roller 21 from deflecting during lifting and lowering, thereby affecting the plastering effect. The guide assembly 27 may be, for example, a guide rod and a guide sleeve, or a guide rail and a slider, a pulley, etc., which will not be described in detail.

[0050] Furthermore, if Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, in this embodiment, the plastering assembly 2 also includes a second plastering roller 26. The second plastering roller 26 is located behind the first plastering roller 21 and has a slower rotation speed than the first plastering roller 21. A smoothing component 22 is provided between the first plastering roller 21 and the second plastering roller 26. The first plastering roller 21 is connected to a rotary drive member 211. The first plastering roller 21 is a fast-rotating paving roller. The second plastering roller 26 passively rotates by means of the friction force in contact with the concrete surface. The second plastering roller 26 is a slow-rotating roller. During plastering construction, the first plastering roller 21 is plastered by rapid rotation, and then the smoothing component 22 smoothes the concrete surface after the initial plastering. Subsequently, the second plastering roller 26 rotates slowly under the action of the friction force in contact with the concrete surface to smooth the concrete surface again, resulting in a better plastering effect. In other embodiments, such as Figure 8 As shown, only the first finishing roller 21 may be retained to simplify the structure and reduce the size of the device.

[0051] Furthermore, if Fig.11 As shown, in this embodiment, the scraping component 22 includes a scraping plate, and both ends of the scraping plate have slopes. The scraping plate can improve the flatness of the concrete surface and make the concrete surface smoother; the scraping plate has slopes at both ends, which can construct concrete with slopes on both sides of the filling layer, and has stronger applicability.

[0052] Furthermore, in this embodiment, the plastering assembly 2 further includes a vibrating member 23 (e.g., a vibrating rod), a transverse track 232 disposed on the plastering trolley 1, and a transverse seat 231 disposed on the transverse track 232. The vibrating member 23 is hinged to the transverse seat 231. The vibrating member 23 can effectively transmit vibration, so that the concrete becomes dense and the surface becomes smooth; Figure 5 As shown, by providing the transverse track 232 and the transverse seat 231, the vibrating member 23 can move laterally, can cover a larger vibrating area, and achieve a better vibrating effect; Figure 7 As shown, the vibrating member 23 is hinged to the transverse displacement seat 231. After the construction is completed, the vibrating member 23 can be rotated upward and retracted for easy storage to prevent damage to the leveled concrete surface.
