[0002] Reservoir water diversion tunnels are quite high and often have multi-layer brackets for installing the foundation of lifting equipment. The operating space is small and the construction is quite difficult.

[0003] The current conventional formwork construction method, which uses scaffolding, has a low degree of mechanization and poor safety assurance. It also takes a long construction period and requires a large amount of materials. After construction, a large amount of manpower is required to remove the formwork from the top of the tunnel downwards, resulting in low efficiency and inconvenient loading and unloading of the formwork and construction components. Utility Model Content

[0004] The purpose of the utility model is to provide a high-height self-contained crane trolley for a reservoir water diversion tunnel, which solves the problems of inconvenient mud discharge and slow floc sedimentation proposed in the above background technology.

[0006] According to at least one embodiment of the present disclosure, a high-height reservoir water diversion tunnel with a self-contained crane trolley has a slide groove opening transversely opened in the middle of the upper surface of the support frame, and the slider is slidably installed in the slide groove opening.

[0007] According to at least one embodiment of the present disclosure, a high-height reservoir water diversion tunnel with a self-contained crane trolley has deflection side forms movably hingedly installed at both ends of the top template, and a diagonal pull cylinder is movably hingedly installed between the lower end of the deflection side template and the supporting beam frame.

[0008] According to at least one embodiment of the present disclosure, a high-height reservoir water diversion tunnel with a self-contained crane trolley, the horizontal pushing mechanism includes a transverse guide rail, two U-shaped slide rails and a push cylinder, the two U-shaped slide rails are fixedly installed side by side on the support frame, and protruding slides are fixedly installed at both ends of the lower part of the transverse guide rail, the protruding slides are slidably connected to the U-shaped slide rails at the corresponding position, and the crane is slidably installed on the transverse guide rail.

Workers can then conveniently complete the installation of the tunnel's top and side formwork. The horizontal push mechanism can control the crane's extension position as needed to facilitate construction. The horizontal push mechanism can pull the crane back onto the support frame to prevent the crane from affecting construction.

[0013] The contraction of the supporting cylinder can lower the height of the top formwork, and then the supporting cylinder is pushed to tilt by the transverse cylinder. At this time, the top formwork can be moved away from the top of the tunnel, realizing the demolding of the top formwork and improving demolding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] For descriptive purposes, this disclosure may use spatially relative terms, such as "below," "beneath," "beneath," "below," "above," "upper," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another component(s) as illustrated in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be oriented "above" the other component or feature. Thus, the exemplary term "below" can encompass both "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0020] like Figure 1 As shown, a high-height self-contained crane trolley for a reservoir water diversion tunnel disclosed in the present invention comprises a trolley body arranged in a tunnel 1, two guide rails 11 are installed on the ground of the tunnel 1, the trolley body is composed of a main portal 2, a support frame 4 and a plurality of sub-portillars 3, the bottom of the main portal 2 is provided with a walking wheel 21 slidably connected to the corresponding guide rails 11, a plurality of sub-portillars 3 are fixedly installed on the main portal 2 in sequence from top to bottom, the support frame 4 is fixedly installed on the sub-portillar 3 at the top position, a support beam frame 5 is provided above the sub-portillar 3, and a support beam frame 5 is fixedly installed on the top of the support beam frame 5. A plurality of supporting screw rods 52 are evenly and detachably installed between the top formwork 6, the support beam frame 5 and the secondary portal frame 3. Both ends of the upper part of the support frame 4 are laterally fixedly installed with a transverse cylinder 41. The piston shaft of the transverse cylinder 41 is movably hingedly installed with a slider. The top of the slider is movably hinged with a supporting cylinder 51. The upper end of the supporting cylinder 51 is movably hinged with the supporting frame 4. Both ends of the upper part of the secondary portal frame 3 at the top position are provided with a horizontal push mechanism 9 and a crane 8. The crane 8 is an electric hoist in the prior art. The horizontal push mechanism 9 is used to drive the crane 8 close to or away from the inner wall of the tunnel 1.

[0021] Furthermore, in this embodiment, a sliding groove is transversely opened in the middle of the upper surface of the support frame 4, and the slider is slidably installed in the sliding groove, so that the transverse cylinder 41 can stably push the supporting cylinder 51 to tilt.

[0022] Furthermore, in order to facilitate the removal of the top template 6, in this embodiment, both ends of the top template 6 are movably hingedly installed with deflection side templates 61, and the lower end of the deflection side template 61 is movably hingedly installed with an inclined pull cylinder 7 between the support beam frame 5.

[0023] like Figure 2As shown, in this embodiment, the horizontal pushing mechanism 9 includes a transverse guide rail 94, two U-shaped slide rails 91 and a push cylinder 93. The two U-shaped slide rails 91 are fixedly installed side by side on the support frame 4. Both ends of the lower part of the transverse guide rail 94 are fixedly installed with protruding slides 92. The protruding slides 92 are slidably connected to the U-shaped slide rails 91 at the corresponding position, and the crane 8 is slidably installed on the transverse guide rail 94.

[0025] In this embodiment, the crane 8 is slidably connected to the transverse guide rail 94 via a driving wheel.

[0026] The specific operation steps are as follows: through the combined structure of the secondary portal frame 3 and the main portal frame 2, after the construction of the bottom layer in the tunnel 1 is completed, the construction of the upper layer can be carried out. The crane 8 is pushed out by the horizontal push mechanism 9. At this time, the crane 8 can lift the formwork and components required for the construction process, and then the workers can conveniently complete the top formwork and side formwork of the tunnel 1.

[0027] When it is necessary to remove the formwork, the support screw rod 52 is removed, and then the inclined pull cylinder 7 is contracted to allow the deflected side formwork 61 to be deflected. At this time, the support cylinder 51 is started again. The contraction of the support cylinder 51 can lower the height of the top formwork 6, and then the support cylinder 51 is pushed to tilt by the transverse cylinder 41. At this time, the top formwork 6 can be moved away from the top of the tunnel 1, and the formwork removal work of the top formwork 6 can be realized. After the top formwork 6 is removed, it is convenient for the staff to remove the side formwork in the tunnel 1.
