Description
Technical Field
The utility model relates to a tunnel construction technical field, more specifically say so and relate to a take hydraulic system's tunnel excavation platform truck.
Background
Need carry out preliminary bracing after the tunnel blasting, often adopt the I-steel to come as the rigid support, erect the I-steel after the tunnel blasting slagging tap and can increase tunnel country rock stability, can strengthen country rock self-supporting ability, have important influence to tunnel stability and security. In the traditional installation process, workers are used for installing I-shaped steel on an excavation trolley in a standing mode, at least 8 persons are needed to be matched with each other one by one, manpower and material resources are wasted, the matching is improper, and safety accidents are easy to happen.
Therefore, how to provide a tunnel excavation trolley with a hydraulic system, which can not only reduce labor cost and shorten construction period, but also well solve the problems of safety, incapability of guaranteeing quality and low efficiency in the installation of i-steel by the traditional excavation trolley, is one of the technical problems that the technical personnel in the field need to solve urgently.
SUMMERY OF THE UTILITY MODEL
In view of this, for solving the problem mentioned in the above-mentioned background art, the utility model provides a take hydraulic system's tunnel excavation platform truck can utilize hydraulic system to assist the installation I-steel through increasing hydraulic system on the excavation platform truck, and reducible workman drops into and labour saving and time saving.
In order to solve the technical problem, the utility model discloses following technical scheme has been taken:
the tunnel excavation trolley with the hydraulic system comprises a rail, a portal frame and a plurality of jacks, wherein the bottom of the portal frame is fixedly connected with a roller and a speed reduction motor and is connected to the rail in a sliding manner through the roller; the rotating shaft of the roller is in transmission connection with the speed reducing motor; a plurality of groups of support columns are symmetrically arranged on two sides of the portal frame, and one end of each support column, which is far away from the portal frame, is fixedly connected with 1 hydraulic jack; an operating platform is fixedly arranged at the top of the portal; two ends of the operating platform are respectively hinged with 1 hydraulic jack.
Preferably, guard railings are fixedly installed around the operating platform.
Preferably, each support column is vertically arranged on the side surface of the gantry, and an inclined strut is fixedly connected between the support column and the gantry.
Preferably, the support columns are arranged in 2 groups.
Preferably, the number of the hydraulic jacks is 6.
The utility model discloses for prior art gain following technological effect:
the utility model discloses an establish operation platform on the portal, the workman can utilize to carry out the I-steel installation, and whole operation platform can remove along with the portal moreover, can be along the continuous construction in tunnel, has promoted the I-steel construction quality of tunnel preliminary bracing, has reduced labour's cost, has shortened the time limit for a project, fine solution safety, quality can not obtain guarantee and the problem of inefficiency in traditional excavation platform truck installation I-steel.
