[0025] This application discloses a hydraulic formwork trolley for tunnel construction. (See also...) Figure 1 and Figure 2 A hydraulic formwork trolley for tunnel construction includes a traveling track 1, a gantry body 2, a formwork mechanism, and a end-blocking plate mechanism. The traveling track 1 is set on the working surface of the tunnel, the gantry body 2 is installed on the traveling track 1, the formwork mechanism is set on the periphery of the gantry body 2, and the end-blocking plate mechanism is set on the periphery of the formwork mechanism.

[0026] Reference Figure 2 The travel track 1 is laid according to the needs of the construction site, so that the travel track 1 extends along a predetermined direction. The travel track 1 is connected to the construction ground by a threaded locking method. The travel track 1 is the basic component for the movement of the trolley, providing the path direction for the movement of the trolley.

[0027] The gantry 2 can move along the direction of the travel track 1, enabling the trolley to switch between different construction positions. The gantry 2 is composed of multiple inverted "U"-shaped frames, and its actual overall length will be manufactured according to the needs of the construction site. It has good stability and load-bearing capacity. The gantry 2 is slidably connected to the travel track 1 through a travel mechanism, which includes a front base plate 11 and a rear base plate 12. Both the front base plate 11 and the rear base plate 12 are rotatably connected to multiple travel wheels 13, which are rolled in the travel track 1. Contact wheels 14 are provided on both sides of the bottom of the gantry 2. The contact wheels 14 are connected to the front base plate 11 and the rear base plate 12, providing auxiliary support. The contact wheels 14 connect the gantry 2 to the front base plate 11 / rear base plate 12, so that the travel wheels 13 can carry the gantry 2 along the direction of the travel track 1 when rolling.

[0028] The front base plate 11 is also provided with a translation component for driving the traveling wheels 13 to roll along the traveling track 1. The translation component includes a drive unit 15 and a gear chain transmission component. The drive unit 15 can be a motor or a hydraulic motor that moves in both directions. The gear chain transmission component transmits the power of the drive unit 15 to the traveling wheels 13, thereby realizing the movement of the trolley.

[0029] Reference Figure 1 and Figure 3 The template mechanism includes a side mold part 3 and a top mold part 31 that are connected to each other. The side mold part 3 specifically includes a left mold 5 and a right mold 54. The side mold part 3 (left mold 5 / right mold 54) and the top mold part 31 are provided with ear plates 32 at their respective ends. The two ear plates 32 are hinged by a pin, so that the side mold part 3 and the top mold part 31 are tightly connected to form a whole. The pin can also be used to disassemble the side mold part 3 and the top mold part 31 and adjust their angle.

[0030] The side mold part 3 is connected to the gantry body 2 via a support mechanism, which includes a hinge seat 4, a hinge joint 41, and a first hydraulic cylinder 42. The hinge seat 4 is located on the outer side of the gantry body 2 and the inner side of the side mold part 3. The hinge joint 41 is hinged to the hinge seat 4 via a pivot. The hinge joint 41 is located at both ends of the first hydraulic cylinder 42. The first hydraulic cylinder 42 can be a multi-stage hydraulic cylinder or a single-stage hydraulic cylinder. The position and angle of the side mold part 3 are adjusted by the extension and retraction of the first hydraulic cylinder 42.

[0031] Reference Figure 1 and Figure 4 The top mold part 31 is connected to the top mold frame 22 located at the top of the gantry body 2. An extension plate 33 is provided on the inner side of the top mold part 31. The extension plate 33 is detachably connected to the top mold frame 22, which can be easily installed and disassembled by bolts or clips. A hinge seat 34 is also provided on the inner side of the top mold part 31. The hinge seat 34 is hinged to the top mold frame 22, allowing the top mold part 31 to be flexibly adjusted in angle.

[0032] Reference Figure 3 The top mold section 31 includes a left top mold 51, a middle top mold 52, and a right top mold 53. Both the left and right top molds 51 and 53 have slots on the side closest to the middle top mold 52. The middle top mold 52 has inserts on both sides, which are inserted into the slots. This insertion method makes the connection of the top mold section 31 tighter and provides better sealing. The middle top mold 52 has a pumping hole for concrete pouring.

[0033] In the connection between the gantry body 2 and the template structure in this application, when facing a larger cross-section of the tunnel passage, it is necessary to adjust the template trolley to meet the profile lining requirements of the cross-section. The following methods can be adopted: For the gantry body 2, an auxiliary gantry is added. This is done by adding an auxiliary gantry to the existing width, and placing the hinge seat 4, which connects to the side mold part 3, on the outside of the newly added auxiliary gantry to achieve the outward expansion of the side mold part 3. For the missing template, a new wide template is added, specifically arranged between the middle top mold 52 and the original left top mold 51 and right top mold 53. The widened template still has a slot on the side closer to the middle top mold 52, and an insert is set on the side closer to the left top mold 51 / right top mold 53. The connection is achieved through the insertion and cooperation of the insert and the slot, thus realizing the increase of the template and the expansion of its size. For the top mold frame 22, the original top mold frame 22 needs to be widened and heightened. An auxiliary column is added between the original extension plate 33 and the top mold frame 22 to continue the connection with the extension plate 33. An auxiliary platform beam is added in the direction of the original top mold frame 22 that is hinged to the hinge seat 34 to meet the requirements of the enlarged cross-section.

[0034] Reference Figure 5 and Figure 6 The end-stopping plate mechanism includes an upper baffle 6 and a lower baffle 61 connected to each other. A gap is provided between the upper baffle 6 and the lower baffle 61, and a waterstop strip is installed within this gap to provide sealing and waterproofing. The width of the gap is greater than the width of the waterstop strip. The bottom of the lower baffle 61 is hinged to the template mechanism, and the bottom of the upper baffle 6 and the top of the lower baffle 61 are hinged together, allowing for flexible position adjustment. The top of the upper template is fitted with a cork 63 to prevent grout leakage; the cork 63 has good elasticity and sealing properties.

[0035] The implementation principle of a hydraulic formwork trolley for tunnel construction in this application embodiment is as follows: the formwork trolley can move flexibly on the tunnel working surface through the traveling track 1 and the traveling mechanism. The side formwork part 3 and the top formwork part 31 of the formwork mechanism are tightly connected into a whole through the support mechanism, the top formwork frame 22 and the gantry body 2, respectively. The waterstop and the cork 63 of the end plate mechanism effectively prevent grout leakage. Therefore, the formwork trolley of this application has the advantages of good stability, high construction efficiency and good forming quality.

After reading this specification, those skilled in the art can make modifications to this specific embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
