[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0027] like Figure 1-3 As shown, a construction trolley for tying steel bars on the outer side of an open-cut tunnel comprises a portal main frame 1, a construction platform 6, a lifting mechanism, and a displacement mechanism. The portal main frame 1 comprises a side frame and a top frame. The side frame is an N-shaped truss welded from I-beams. The length of the side frame in the length direction of the open-cut tunnel is adapted to the length of the steel bar tying trolley. The top frame is a plane truss welded from I-beams, which is equivalent to connecting the side frames on both sides into a portal-shaped whole. The portal main frame 1 is spanned above the open-cut tunnel and corresponds to the steel bar trolley. In the process of tying steel bars on the steel bar trolley, steel bars are tied on the outer side of the steel bar trolley through the portal main frame 1.

[0028] The present application also provides a construction platform 6, which is arranged on the portal frame and is used to support construction personnel in carrying out steel bar binding work. The length of the construction platform 6 is compatible with the length of the steel bar trolley corresponding to the open-cut tunnel, so that the entire section of the tunnel to be constructed can be steel-bound. The construction platform 6 is a steel frame with a flat upper surface. Multiple construction platforms 6 can be arranged on each portal frame. Preferably, there are two construction platforms 6, and the two construction platforms 6 are respectively located on both sides of the portal main frame 1, so that independent construction can be carried out on both sides of the steel bar trolley, thereby improving construction efficiency.

[0029] Each construction platform 6 is provided with at least two lifting mechanisms for longitudinal driving. Taking two as an example, the two lifting mechanisms are respectively located at the two ends of the lifting mechanism. If there are three lifting mechanisms, the three lifting mechanisms are respectively located at the two ends and the middle of the lifting mechanism.

[0030] The lifting mechanism is correspondingly connected between the construction platform 6 and the portal main frame 1 to drive the construction platform 6 to rise and fall in the longitudinal direction; in order to ensure displacement in the circumferential direction of the tunnel, the present application also provides a displacement mechanism, and multiple displacement mechanisms are connected one by one with multiple lifting mechanisms to drive the construction platform 6 to move in the direction of the open-cut tunnel along the horizontal plane, thereby driving the construction platform 6 in a horizontal and longitudinal linkage manner, and then constructing the tunnel reinforcement in all directions.

[0031] In an optional embodiment, the lifting mechanism is a winch 4, which is provided with a steel cable 7 connected to a construction platform 6. The free section of the steel cable 7 is connected to the construction platform 6 through a hook. A fence 5 can be set on the construction platform 6, and the steel cable 7 is correspondingly hoisted on the fence 5.

[0032] The displacement mechanism is a pulley 3, and the winch 4 is fixed on the pulley 3 accordingly. A guide rail 2 corresponding to the pulley 3 is provided above the portal main frame 1 to drive the lifting mechanism to move through the pulley 3.

[0033] In this embodiment, the displacement mechanisms corresponding to the same construction platform 6 are synchronously driven during the lateral displacement process, and the lifting mechanisms corresponding to the same construction platform 6 are synchronously driven during the longitudinal movement process.

[0034] In an optional implementation, the guide rail 2 is an I-beam, which is fixed on the top price by welding. The guide rail 2 is an I-beam, and rollers 8 are provided on both sides of the pulley 3, which slide on both sides of the I-beam respectively. The rollers 8 are supported on the upper surface of the lower flange of the I-beam. At least one of the rollers 8 is correspondingly connected to the first drive motor 9, and is driven by the first drive motor 9 to move along the I-beam.

[0035] A driving wheel is provided under the portal main frame 1, and the driving wheel moves along the landing platforms on both sides of the open-cut tunnel. The landing platforms are made of concrete, and tracks corresponding to the driving wheels can be laid on the landing platforms. The driving wheels are connected to the second driving motor. At least two driving wheels are provided on each side of the portal frame, and at least the two driving wheels corresponding to the front side of the portal frame are connected to the second driving motor, so that different sections of the tunnel can be moved by displacing the second driving motor.

[0036] In an optional embodiment, a fence 5 is provided above the construction platform 6. The fence 5 is welded and fixed to the construction platform 6 and can be formed by welding steel pipes. Two horizontal strut groups extend from the side of the fence 5 corresponding to the center line of the open-cut tunnel. The two horizontal strut groups are respectively located in the middle and lower edge of the fence 5. Each horizontal strut group includes a plurality of horizontal struts 11 evenly distributed along the length direction of the construction platform 6. The horizontal struts 11 are installed on the fence 5 in the horizontal direction in the form of threaded assembly to support the outer surface of the steel bar trolley. Specifically, during the process of binding the middle and lower steel bars, the two horizontal support groups can support the steel bar trolley, thereby ensuring the stability of the construction platform 6 to ensure that the construction platform 6 will not shake during the construction process.

[0037] Furthermore, when the construction platform 6 reaches the upper part or the top of the tunnel, the horizontal support group cannot support the outer surface of the steel trolley. Therefore, the present application also provides a longitudinal strut group. Specifically, two longitudinal strut groups are provided under the construction platform 6. The two longitudinal strut groups are respectively located in the middle of the construction platform 6 and on the side edge close to the center line of the open-cut tunnel. Each longitudinal strut group includes a plurality of longitudinal struts 10 evenly distributed along the length direction of the construction platform 6. The longitudinal struts 10 are longitudinally assembled on the construction platform 6 by threaded assembly to support the outer surface of the steel trolley. When the construction reaches the tunnel top plate position, it can be supported by the longitudinal struts 10.

[0038] In this embodiment, a horizontal screw sleeve extending horizontally corresponding to the horizontal support rod 11 is provided on the fence 5, and the horizontal support rod 11 is threadedly assembled in the horizontal screw sleeve.

[0039] Correspondingly, a longitudinal threaded sleeve is provided at the bottom of the construction platform 6, which penetrates and extends longitudinally. The longitudinal support rod 10 is threadedly assembled in the longitudinal threaded sleeve. The extension length of the horizontal support rod 11 and the longitudinal support rod 10 is adjusted according to the position of the steel bar trolley to ensure the stability of the support.

[0040] In an optional embodiment, each longitudinal strut group includes two longitudinal struts 10, which are correspondingly arranged at both ends of the construction platform 6, so as not to extend upward in the middle of the construction platform 6 and affect walking.

[0041] The corresponding horizontal support rods 11 extending into the fence 5 will not affect the normal construction, but in order to minimize the impact, each horizontal support rod group has two horizontal support rods 11, which are respectively located at the two ends of the fence 5.

[0042] Support plates are hinged at the ends of the horizontal support rods 11 and the longitudinal support rods 10. The support plates have high-strength magnets on one side close to the steel bar trolley. The magnets have an arc-shaped surface corresponding to the outer surface of the steel bar trolley, thereby improving the support stability through magnetic attraction.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
