Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a plastering device suitable for invert filling layers with different slopes. Background Art

[0002] With the rapid progress of tunnel construction technology in my country, construction efficiency and quality standards have gradually improved. During the construction of the tunnel invert filling layer, the requirements for the quality of concrete surface molding are particularly stringent, which has led to a growing demand for filling layer finishing equipment. In the current double-track tunnel construction plan, there are three main ways to install the finishing device: the finishing device is installed between the invert formwork on the left and right sides, the finishing device is installed between the center ditch formwork and the invert formwork, and the finishing device is installed on the trestle.

[0003] Among them, the most common installation method is to install the plastering device between the left and right inverted arch formworks. However, this positioning method is not only difficult to ensure accuracy, but also cannot adapt well to the transverse slope of the inverted arch filling layer, and affects the installation and use of the inverted arch formwork. In addition, because the power source of the plastering device is configured on both sides of the center ditch, the power synchronization is poor, which increases the failure rate of the equipment walking. The overall structural rigidity of the equipment is also insufficient due to space limitations and is prone to deformation. If you try to solve this problem by increasing the positioning points of the center ditch, it may cause more positioning inaccuracies due to the increase in positioning points; the installation method in which the plastering device is installed between the center ditch formwork and the inverted arch formwork allows the plastering device to be constructed on the left and right sides with the center ditch as the boundary. However, this installation method requires the plastering device to be rearranged when the transverse and longitudinal slopes of the inverted arch filling layer change due to terrain changes and drainage requirements, which is time-consuming and laborious; the method in which the plastering device is installed on the trestle has high requirements for the centering of the trestle. Although the lifting function is designed, it is still challenging to achieve accurate control of the elevation of the plastering device, especially in the case of longitudinal slopes, and the operation is complicated. This not only requires the trestle to have extremely high positioning accuracy for the plastering device, but also when the trestle needs to bear the passage of vehicles, the interference of vehicle traffic on the plastering operation is almost inevitable.

[0036] Embodiment 1

[0037] Figures 4 to 11 An embodiment of the utility model is shown, which is suitable for a plastering device with different slopes of an inverted arch filling layer. The plastering device with different slopes of an inverted arch filling layer comprises a longitudinal track 2, a running mechanism 3 and a plastering mechanism 4. The longitudinal track 2 is arranged on the longitudinal beam of the center groove template 1, the running mechanism 3 is arranged on the longitudinal track 2, the plastering mechanism 4 is arranged on the running mechanism 3, the plastering mechanism 4 comprises a cross beam 41, a plastering portion is arranged at the bottom of the cross beam 41, and the cross beam 41 is hinged to the running mechanism 3 to adjust the lateral inclination angle.

[0038] The plastering device of the embodiment is applicable to different slopes of the inverted arch filling layer. The longitudinal track 2 is set on the longitudinal beam of the center trench template 1, and the longitudinal beam of the center trench template 1 is relied on to achieve accurate positioning. The plastering mechanism 4 is completely independent of the trestle and the inverted arch template, so as not to affect the functions of the trestle and the inverted arch template. The running mechanism 3 moves along the longitudinal track 2, driving the plastering mechanism 4 to smooth the concrete on the surface of the inverted arch filling layer, so that the plastering mechanism 4 can adapt to the change of the longitudinal slope of the inverted arch filling layer. The crossbeam 41 is hinged with the running mechanism 3 so that the crossbeam 41 can change its inclination angle, thereby enabling the plastering mechanism 4 to adapt to the change of the transverse slope of the inverted arch filling layer. The plastering device of the embodiment is applicable to different slopes of the inverted arch filling layer. It is not necessary to reposition and install the plastering mechanism 4 during the plastering process to adapt to the change of the longitudinal and transverse slopes of the inverted arch filling layer. The construction efficiency is high, and the operation is simple, the use is convenient, the precision and stability of the plastering work are high, and the whole can be moved toward the next construction area with the center trench template 1, and the arrangement is convenient.

[0039] As a preferred embodiment, the bottoms of both ends of the cross beam 41 are provided with plastering parts, and the two plastering parts are respectively located on the left and right sides of the central trench template 1. The plastering mechanism 4 can plaster the inverted arch filling layers on the left and right sides of the central trench template 1, reducing the number of related parts and reducing costs.

[0040] Furthermore, in the present embodiment, a lifting component 5 is provided between the longitudinal track 2 and the longitudinal beam of the center groove template 1, and the lifting component 5 is preferably an oil cylinder, and is provided at the front and rear ends of the longitudinal beam of the center groove template 1. When the cross beam 41 is at different inclination angles, the height of the cross beam 41 can be adjusted by the lifting component 5, so that the plastering surface and the surface of the inverted arch filling layer are more closely fitted, thereby improving the compaction effect during the plastering process. At the same time, when the cross beam 41 is in a jacking state, the plastering surface is separated from the surface of the inverted arch filling layer, which facilitates the demoulding of the center groove template 1 and prevents the cross beam 41 from extending into the inverted arch filling layer during the demoulding process, thereby destroying the completed plastering work. Of course, in other embodiments, the lifting component 5 can be a cylinder, a screw nut pair, and other components, and the specific structure will not be repeated.

[0041] Furthermore, in this embodiment, the running mechanism 3 includes a running frame 31 and a driving assembly 32. The running frame 31 is provided with a guide member 311 for cooperating with the longitudinal track 2. The driving assembly 32 includes sprockets 321 provided at both ends of the longitudinal track 2, a chain 322 wound around the sprockets 321, and a second rotating driving member 323 connected to one of the sprockets 321. The running frame 31 is connected to the chain 322. The rotation of the second rotating driving member 323 drives the chain 322 to move, thereby driving the running frame 31 to move. The structure is simple and the transmission is reliable, which can ensure that the plastering mechanism 4 and the running mechanism 3 can stably move along the longitudinal track 2. Of course, in other embodiments, the running mechanism 3 can also be driven to move along the longitudinal track 2 by gears, oil cylinders, etc., and the specific structure will not be repeated.

[0042] Furthermore, in this embodiment, the plastering device suitable for different slopes of the inverted arch filling layer also includes a mounting seat 6, two longitudinal tracks 2 are provided, and are respectively arranged on the left and right sides of the mounting seat 6, the upper part of the mounting seat 6 is connected to the sprocket 321, and the lower part of the mounting seat 6 is connected to the lifting component 5. The running mechanism 3 moves on the two longitudinal tracks 2 through the guide member 311, which is conducive to improving the stability and safety during the running process, and ensuring the movement accuracy to avoid deviation.

[0043] Furthermore, in this embodiment, the longitudinal track 2 is a cylindrical track, and the guide member 311 is a guide sleeve 7 and is sleeved on the longitudinal track 2, which can prevent the guide member 311 from shaking left and right during movement and derailing, thereby enhancing the stability of the cooperation between the guide member 311 and the longitudinal track 2.

[0044] Furthermore, support wheels 44 are provided at both ends of the cross beam 41, and support guide rails 91 for providing support for the support wheels 44 are provided on the arch formwork 9. When the cross beam 41 is adjusted to an inclination angle that adapts to the lateral slope of the arch filling layer, the support guide rails 91 cooperate with the support wheels 44 to lock the inclination angle of the cross beam 41 and reduce the resistance of the cross beam 41 during longitudinal movement. The structure is simple and reasonable.

[0045] The method of using the plastering device of the present embodiment, which is applicable to different slopes of the inverted arch filling layer, is as follows:

[0046] After the inverted arch filling layer is poured, first adjust the inclination angle of the crossbeam 41 according to the transverse slope of the inverted arch filling layer, and use the support rail 91 and the support wheel 44 to lock the angle of the crossbeam 41. Then, adjust the height of the crossbeam 41 by the lifting component 5 to ensure that the plastering surface contacts the surface of the inverted arch filling layer. After starting the second rotating drive member 323, the sprocket 321 starts to rotate and drives the running frame 31 fixed on the chain 322 to move, and the crossbeam 41 moves along the longitudinal track 2 with the running frame 31 to perform the plastering work. Until the plastering work of the inverted arch filling layer is completed, the lifting component 5 adjusts the height of the crossbeam 41 so that the crossbeam 41 leaves the surface of the inverted arch filling layer, and then shrinks the center trench template 1. Finally, the plastering device with different slopes of the entire inverted arch filling layer moves to the next construction area together with the center trench template 1, ready for the plastering work of the next construction interval.

[0047] It should be noted that when the inverted arch filling surface is horizontal, the crossbeam 41 can also be rotated to a horizontal state, and the inverted arch filling layer on both sides of the center ditch template 1 can be plastered at the same time. Since the traveling frame 3 is driven by a single power source, the synchronization of the two ends of the crossbeam 41 is good.

[0048] Embodiment 2

The structure of the plastering device of different slopes of the inverted arch filling layer of this embodiment is roughly the same as that of the first embodiment, except that:

[0050] In this embodiment, the bottom of both ends of the crossbeam 41 is provided with a plastering member 42, and the plastering member 42 is a plastering roller 421. The two plastering rollers 421 are respectively located on the left and right sides of the central groove template 1. Compared with the first embodiment, the plastering roller 421 can provide better compaction and smoothing effects. Of course, in other embodiments, the plastering member 42 can be other plastering components such as a plastering panel, which will not be described in detail.

[0051] Furthermore, in this embodiment, a first rotating driving member 43 is provided on the crossbeam 41, and the first rotating driving member 43 is connected to the plastering roller 421. The plastering roller 421 can be actively rotated under the drive of the first rotating driving member 43, and the plastering effect is better. Of course, in other embodiments, the plastering roller 421 can also be passively rotated by contacting the surface of the invert filling layer during the movement.

The structure of the plastering device of different slopes of the inverted arch filling layer of this embodiment is roughly the same as that of the first embodiment, except that:

[0054] In this embodiment, the guide member 311 is a guide wheel 8, and each longitudinal track 2 includes two upper and lower parts, each of which is provided with a guide member 311. Compared with the first embodiment, the guide wheel 8 has less friction when moving on the longitudinal track 2, and moves more smoothly.
