[0002] Lining trolleys are generally used for the secondary lining construction of tunnel projects. During the secondary lining construction, the lining trolley is first installed and fixed, and then the concrete pump truck delivers concrete to the trolley working window and grouting port through the concrete delivery pipe. When grouting through the grouting port, concrete can easily penetrate into the gap of the grouting port, causing the grouting port opening and closing gate to get stuck after the concrete solidifies.

[0023] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 , 2As shown, a hydraulic opening and closing grouting port for a lining trolley comprises a rear end ear plate 1 of the oil cylinder, a rear end pin shaft 2 of the oil cylinder, an oil cylinder 3, a first pin shaft 4 for installing the grouting port, The pin shaft 5 at the front end of the cylinder, the inner bucket 6, the outer bucket 7 and the second pin shaft 8 are installed at the grouting port. The inner bucket 6 and the outer bucket 7 are respectively fixed to the mounting and fixing plate of the template through the first pin shaft 4 installed at the grouting port and the second pin shaft 8 installed at the grouting port. The inner bucket 6 is hinged with the first pin shaft 4 installed at the grouting port and the outer bucket 7 so that the inner bucket 6 and the outer bucket 7 form an inner and outer outer fitting relationship. There is a movable gap between the inner bucket 6 and the outer bucket 7 so that the inner bucket 6 can rotate around the first pin shaft 4 installed at the grouting port inside the outer bucket 7; the bottom of the ear plate 1 at the rear end of the cylinder is fixed to the waist plate of the template by welding, the rear end of the cylinder 3 is pin-connected with the ear plate 1 at the rear end of the cylinder through the pin shaft 2 at the rear end of the cylinder, and the front end of the cylinder 3 is pin-connected with the lower ear plate of the inner bucket 6 through the pin shaft 5 at the front end of the cylinder. The extension and contraction of the cylinder 3 drives the inner bucket 6 to rotate around the first pin shaft 4 installed at the grouting port to realize the opening or closing of the grouting port.

[0025] like Figure 5 , 6 As shown, the inner bucket 6 includes an inner bucket top plate 601, a cylinder connecting ear plate 602, an inner bucket side plate 603 and an inner bucket arc plate 604. The inner bucket top plate 601 coincides with the opening position of the template panel, and the size of the inner bucket top plate 601 matches the size of the panel opening; a cylinder connecting hole is provided on the cylinder connecting ear plate 602, and the front end of the cylinder 3 is connected to the cylinder connecting ear plate 602 through the front end pin shaft 5 of the cylinder, and an installation connecting hole is provided on the inner bucket side plate 603. The inner bucket 6 is driven to rotate around the first pin shaft 4 installed at the grouting port through the telescopic action of the cylinder 3.

[0026] like Figure 7 , 8 As shown, the outer bucket 7 includes an outer bucket side plate 701, an outer bucket connecting pipe 702, an outer bucket arc plate 703 and an outer bucket top plate 704, and a left installation connection hole and a right installation connection hole are respectively opened on the left and right sides of the outer bucket side plate 701, and the first grouting port installation pin shaft 4 and the second grouting port installation pin shaft 8 are respectively connected with the installation fixing plate connecting pin hole of the template through the left installation connection hole and the right installation connection hole; the end of the outer bucket connecting pipe 702 is provided with a connecting flange for connecting to a concrete conveying pipe; the outer bucket arc plate 703 is welded and fixed to the outer bucket connecting pipe 702, and a circular hole is opened at the connection between the outer bucket arc plate 703 and the outer bucket connecting pipe 702, so that concrete enters the outer bucket 7 from the opening of the outer bucket arc plate 703, flows out through the top of the outer bucket 7 and enters the inside of the template.

[0027] like Figure 3 , 4As shown, the formwork structure is mainly composed of a formwork panel, a formwork waist plate, a formwork rib plate and a mounting plate. The rear end ear plate of the oil cylinder is welded on the inner side of the left waist plate for connecting the rear end of the oil cylinder. A hole is opened on the formwork panel, and the concrete enters the interior of the formwork through the hole during grouting. A grouting port mounting plate is set inside the formwork, and a connecting pin hole is opened on the fixing plate for installing the inner and outer buckets of the grouting port.

[0028] The working process of the utility model is as follows:

[0029] 1. Initial state

[0030] like Fig. 9 As shown, before grouting, first close all grouting ports and wait for grouting.

[0031] 2. Grouting status

[0032] like Fig.10 As shown, when grouting is required at a certain grouting port, first connect the concrete delivery pipe 15 to the outer bucket connecting pipe 702, then operate the oil cylinder 3 to shrink the piston rod, drive the inner bucket 6 to rotate downward around the first pin shaft 4 installed at the grouting port, and open the inner bucket 6 to connect the concrete delivery pipe 15 with the inside of the template through the outer bucket 7. At this time, start the concrete pump truck, and the concrete is injected into the template through the concrete delivery pipe 15, the outer bucket connecting pipe 702, and the inner cavity of the outer bucket from the opening of the top panel of the template.

[0033] 3. Grouting port closure

[0034] like Fig.11 As shown, after pouring is completed, the oil cylinder 3 is operated to extend the piston rod, driving the inner bucket 6 to rotate upward around the first pin shaft 4 installed at the grouting port, and the inner bucket 6 is closed. The inner bucket top plate 601 blocks the opening of the template panel, so that the poured concrete cannot flow out of the template from the grouting port downward, thereby achieving the closure of the grouting port.

[0035] Opening after subsequent demoulding

[0036] After the formwork is demoulded, the grouting port needs to be opened. Since the concrete is in a mud state during pouring, a small amount of concrete will inevitably flow into the matching gap between the inner and outer buckets. After the concrete solidifies, it is very hard, and the resistance to opening the inner bucket will also be very large. However, since the grouting port is opened by the oil cylinder 3, the oil cylinder 3 has sufficient power to overcome the resistance generated by the small amount of concrete in the matching gap between the inner and outer buckets. The hydraulic system is operated to shrink the oil cylinder 3, and the grouting port can be opened smoothly. At this point, a working cycle of the hydraulic opening and closing of the grouting port is completed.

[0037] The utility model is cleverly designed, has rapid transmission action, is easy to control, reduces manual operation, reduces labor intensity, improves work efficiency, and ensures safe and stable operation of the trolley. It solves the problem that the grouting port of the existing traditional lining trolley is opened and closed by manual push-pull, and the grouting port cannot be opened due to limited manual operation force, which seriously affects work efficiency. Compared with the existing technology, it has good market prospects and development space.

[0038] The preferred specific implementation modes and embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation modes and embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the concept of the utility model.
