Problems solved by technology
[0006] The existing technology has many disadvantages, mainly including the compact space of the shield machine, and the upper space is not easy to operate; after the wheel is adjusted, it is fastened by bolts, and the wheels are always under force, and the bolts are easy to loosen after a long time of use; If the 4 wheels are not on the same plane, the feet will be tilted, and the force on the wheels will be uneven; it is difficult for a single person to operate, and sometimes an auxiliary tool (chain hoist) is needed to assist in lifting; the weight of the adjusting bolt includes the trolley itself and the driving trolley During the adjustment process, the bolts are loosened, and the wheels are not perpendicular to the track surface, which is prone to skewing; there are too many screws to be tightened during the adjustment process, a total of 16 screws are required, and the process is cumbersome

Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] see Figure 1~6 , in an embodiment of the present invention, a portable sprocket chain drive trolley includes an upper trolley, a lower trolley and an active frame, the upper trolley is self-contained, and the wheels are fixed and installed to ensure that the four load-bearing wheels are completely on a horizontal plane. All are in contact with the track surface, and the force is uniform, and the wheels are always perpendicular to the track surface; the...

The invention discloses a portable handcart drived by a sprocket and a chain, comprising an upper handcart, a lower handcart and a driving bogie. The handcart driving bogie is I-shaped and the bottom the same has a fixed block of the chain fixed on the middle. And the driving chain is fixed on the fixed block of the chain. The upper handcart comprises four wheels and two upper handcart side panels, wherein the wheels are arranged inside the upper side panels and two wheels are arranged at each upper side panel on the same weight with the other side panel. An upper handcart cage is arranged between two upper handcart side panels where clamping bolts are installed. The lower handcart comprises two lower handcart side panels. The portable handcart drived by a sprocket and a chain optimizes the installation process and has the advantages of simplifying adjusting program after optimization, prolonging the facility practical life expectancy, reducing fault points and relieving the workers labor intensity.
Description
technical field [0001] The invention relates to a relatively large range, in particular to a portable trolley driven by a sprocket and chain. Background technique [0002] The full name of the shield machine is the shield tunnel boring machine. It is a special construction machine for tunneling. The modern shield boring machine integrates light, machinery, electricity, hydraulics, sensing, and information technology. It has the ability to excavate and cut soil. , Conveying soil muck, assembling tunnel lining, surveying, guiding and rectifying deviations and other functions, involving geology, civil engineering, machinery, mechanics, hydraulics, electricity, control, surveying and other disciplines and technologies, and "tailor-made" design according to different geology Manufacturing requires extremely high reliability. Shield boring machines have been widely used in subway, railway, highway, municipal, hydropower and other tunnel projects. In our country, it is customary ...
