Problems solved by technology

[0008] Use large-scale special machinery for steel arch installation and ancillary operations, equipped with a traveling mechanism, use multifunctional hydraulic arms to clamp the steel arch for installation, but still connect the steel arch in the air, and manually connect the bolts
Although the installation speed of the steel arch is fast, it requires experienced operators to quickly operate the hydraulic arm for steel arch docking; because it is a special machine, it does not have the function of the original steel platform as a blasthole construction platform, and the blasthole construction must be done after the operation is completed. The next cycle of work can only be carried out after the platform is placed in place, thus increasing the time for equipment to enter and leave the site. As far as the entire tunnel construction is concerned, this construction method is more time-consuming than manually installing steel arches, and the cost of machinery procurement is high, and the operation and maintenance are complicated. Difficult to promote

Embodiment 1

[0049] A tunnel multifunctional construction trolley, comprising a frame, a walking drive mechanism, a lifting mechanism, a transport mechanism, a lifting mechanism and an outrigger mechanism, a platform 1 is arranged on the top of the frame, and the lifting mechanism is arranged on the front of the frame It is used to lift the steel arch. The transport mechanism is set on the platform 1 to transport the steel arch lifted by the lifting mechanism. The lifting mechanism is fixed on the transport mechanism to lift the top arch 2 to the installation position. The outrigger mechanism is set on the frame The top is used to adjust the position of the frame, and the traveling drive mechanism is arranged at the bottom of the frame to drive the frame to move.

[0050] In the present invention, the lifting mechanism includes a delivery platform 3, a lifting track 4 and a lifting drive device. The lifting track 4 is two and is fixedly arranged on the front of the frame. The delivery platf...

Embodiment 2

[0062] In the present invention, the lifting mechanism is installed in the lifting mechanism track through rollers, and can move up and down through the lifting mechanism hoist. The rollers of the transport trolley are installed in the sunken track of the platform, driven by a hydraulic motor, and can move forward and backward on the platform. The telescopic beam of the bracket is installed in the sliding seat of the trolley frame. One end of the oil cylinder of the trolley is hinged with the telescopic beam, and the other end is hinged with the sliding seat of the frame.

[0063] The bracket is provided with a lifting arm sliding seat, and the lifting arm is installed therein. One end of the lifting arm oil cylinder is hinged with the lifting arm sliding seat, and the other end is hinged with the lifting arm.

[0064] exist figure 1 shows the process of lifting and transferring the steel arch by the bracket, in figure 2 The lifting process is shown in .

Abstract

The invention discloses a multifunctional tunnel construction trolley. The multifunctional tunnel construction trolley comprises a chassis, a walking driving mechanism, a hoisting mechanism, a transporting mechanism, a lifting mechanism and a supporting leg mechanism, wherein a platform is arranged at the top of the chassis; the hoisting mechanism is arranged on the front surface of the chassis and is used for hoisting a steel arch; the transporting mechanism is arranged on the platform and is used for transporting the steel arch hoisted by the hoisting mechanism; the lifting mechanism is fixedly arranged on the transporting mechanism and is used for lifting a top arch to a mounting position; the supporting leg mechanism is arranged on the chassis and is used for regulating the position of the chassis; the walking driving mechanism is arranged at the bottom of the chassis and is used for driving the chassis to move. The multifunctional tunnel construction trolley can be applied to steel arch mounting, anchor bolt spraying and hole drilling operations, and can stimulate a steel arch manual mounting manner and a relative flow of the original simple trolley; the manual mounting manner is replaced with a mechanical mounting manner, no special requirement on the construction organization and the construction site exists, and operations are simple.

Description

technical field [0001] The invention relates to a tunnel machine, in particular to a tunnel multifunctional construction trolley, which belongs to the technical field of tunnel construction equipment. Background technique [0002] In the drilling and blasting tunnel construction, when the surrounding rock with poor self-stability is encountered, the initial support should be carried out immediately after the excavation process: install steel arches, hang nets, and carry out concrete spraying operations to consolidate the tunnel and prevent The tunnel collapsed. [0003] The installation of the steel arch means that each section is usually divided into 3 sections, and the steel arch connected by flange bolts between each section is installed on the circular excavation surface of the tunnel, and is welded and positioned with the anchor rod driven into the surrounding rock in advance. [0004] The current method of steel arch installation is usually to use a simple steel platf...
