Description
Technical Field
[0001] This utility model belongs to the technical field of drilling rig auxiliary equipment, and relates to the track frame structure of a water-cutting wall drilling rig. Background Technology
[0002] A cutoff wall is constructed aft of the dam, a water-retaining structure. Located behind the dam, the cutoff wall is constructed using trench-grooved concrete. Construction employs a method of "staged trenching and hole drilling with impact drilling + main hole drilling followed by auxiliary holes in each section + skipping holes in each section + mud slurry wall protection." The equipment used for trenching and hole drilling is an impact drill, with a drill bit weight of 6.0t and a drilling rig weight of 10.5t. The impact drill is positioned on laid rails parallel to the cutoff wall axis, with the rails laid upstream along the guide groove. An alternating forward movement method ensures smooth rig movement, and the rails are connected to the sleepers using track spikes. However, the existing impact drill directly drills on the rails, generating excessive impact force that can damage the rails, increase the risk of poor hole quality, and increase the frequency of equipment movement, thus increasing construction time and cost. These adverse factors severely impact the construction progress of the cutoff wall, becoming a major challenge in its construction.
[0003] In summary, existing technologies suffer from the problems of inconvenient movement and construction of water-cutting wall drilling rigs. Utility Model Content
[0004] The purpose of this utility model is to provide a track frame structure for a water-cutting wall drilling rig, which solves the problems of inconvenient movement and construction of water-cutting wall drilling rigs in the prior art.
[0005] The technical solution adopted by this utility model is a water-cutting wall drilling rig track frame structure, including a steel plate set on one side of the water-cutting wall, a bottom pressure-bearing module set on the steel plate, a movable pressure relief module slidably connected to the bottom pressure-bearing module away from the steel plate, and an impact drilling rig set on the movable pressure relief module away from the bottom pressure-bearing module.
[0006] The features of this utility model also include:
[0007] The bottom pressure-bearing module includes several parallel sleepers, one side of which is attached to a steel plate, and the axis of the sleepers is perpendicular to the extension direction of the cutoff wall. Each sleeper includes two wooden posts, and the ends of the two wooden posts are fixed together with nails.
[0008] Several parallel light rails are attached to the side of the sleeper away from the steel plate, and the extension direction of the light rails is parallel to the extension direction of the cutoff wall. The light rails are respectively set at both ends of the sleeper, and the light rails and sleepers are fixed together by track spikes.
[0009] Several steel bars are installed between the sleepers and the light rail, and the steel bars are perpendicular to the extension direction of the light rail track; several light rails are fixedly connected to the steel bars.
[0010] The bottom pressure-bearing module also includes a fine sand layer. One side of the fine sand layer is flush with the outer wall of the light rail away from the sleepers, and the other side is attached to the steel plate. The sleepers and light rail are set inside the fine sand layer.
[0011] The mobile pressure relief module includes a platform, one side of which is attached to the impact drilling rig, and the other side is provided with several I-beam columns arranged in parallel; several bearings are fixed to the side of the I-beam columns away from the platform.
[0012] The mobile pressure relief module also includes several rail wheels, which are fitted into the light rail; the rail wheels are connected to the I-beam column via bearings.
[0013] Lifting lugs are provided on both sides of the bottom pressure-bearing module, and the lifting lugs are fixedly connected to the steel plate.
[0014] The cutoff wall consists of a concrete wall with guide grooves on both sides; a steel plate is placed on the side of the guide groove away from the concrete wall.
[0015] The beneficial effects of this utility model are as follows: This utility model combines the construction method of impact drilling rig with the actual on-site construction conditions, fixes the impact drilling rig on the welded frame, and sets rail wheels at the bottom of the frame. The rail wheels are combined with light rails, which effectively reduces the damage of the impact force of the impact drilling rig to the rail wheels, reduces the hole position deviation caused by vibration, reduces the crane investment and personnel investment required for multiple transfers of the drilling rig, and effectively shortens the construction period and reduces the construction cost.
