In the tunnel, the dismantling and the installation of the cable trench cover plate are usually operated under the condition of traffic, so that the construction operation is required to be completed in a short time to reduce the accident occurrence probability, due to the lifting device, the two L-shaped clamping plates 306 clamp and lift the cover plate upwards, the lifting chain 303 is driven by the winch 301 to drive the cross lever 304 to tighten under the action of gravity, the L-shaped clamping plates 306 generate clamping force and upward lifting force on the cover plate, the structure is simple, the operation is convenient, and the operation time is saved. Due to the first object placing table 1, the damaged cover plate can be stored in the first object placing table 1 when the cover plate is opened, so that the transportation and counting of the quantity which needs to be replaced are facilitated. Because the second object placing table 2 is arranged, the tool box on the second object placing table is internally provided with the construction tool and the protection tool, articles in the tool box can be prevented from falling off in the movement process of the trolley, meanwhile, workers do not need shoulder and back construction tool bags, and the tool box is placed into the shell, so that the load of the workers is reduced. Due to the fact that the movable cable reel 11 is arranged, a guarantee is provided for the power source of cover plate construction, and cover plate construction operation in a long-distance tunnel can be met.
Example 2
This embodiment provides a tunnel cable trench cover installation dolly, and embodiment 1 is different, see fig. 3, twine rope 302 end-to-end connection has two drive mechanism, and every drive mechanism connects a pair of L type splint 306, can carry out centre gripping and lift to a plurality of positions of apron, has kept the horizontal stability of cable trench cover when lifting by crane, has reduced the inclination probability when lifting by crane.
Example 3
This embodiment provides a tunnel cable trench cover mounting trolley, which is different from embodiment 2 in that, referring to fig. 4-5, the lifting device is slidably connected to the cross bar 6 through a sliding assembly 12, the sliding assembly 12 can drive the lifting device to slide longitudinally along the cross bar 6, and the sliding assembly 12 can be fixed with the cross bar 6. Manual pushing and pulling the winch 301 can enable the sliding assembly 12 to transversely slide in the sliding hole of the cross rod 6, namely, different positions of the longitudinal overhanging end of the cross rod 6 of the lifting device can be adjusted through the sliding assembly 12, and under the condition that the movable wheels at the bottom of the trolley are fixed, the lifting position can be conveniently adjusted when the cable trench cover plate is lifted in the tunnel, so that the construction operation lifting position is more accurate, and the operation is convenient.
In this embodiment, as shown in fig. 5, the cross bar 6 is in a circular tubular structure, a notch is formed on the lower side of the cross bar 6 along the longitudinal direction of the cross bar, the sliding assembly 12 includes a sliding tube 1201, a vertical connecting block 1202 and a horizontal connecting plate 1203, the sliding tube 1201 is disposed inside the cross bar 6, the sliding tube 1201 can slide along the longitudinal adaptation of the cross bar 6, the vertical connecting block 1202 passes through the notch of the cross bar 6 to connect the sliding tube 1201 and the horizontal connecting plate 1203, and the horizontal connecting plate 1203 is used for connecting the lifting device. By adopting the sliding component 12, the guiding effect is good, the sliding is convenient, the position of the lifting device at the cross rod 6 is convenient to adjust, the sliding process is supported stably, and the operation is safe.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
