Abstract
The utility model relates to a casing pipe compaction device for navigation channel drilling machines, comprising a drilling frame. A compaction oil cylinder is arranged on the drilling frame; the compaction oil cylinder is connected with an inner tube set; the outside of the inner tube set is connected with an outer tube set; a casing pipe clamp is arranged on the outer tube set; the casing pipe clamp can move up and down along with the expansion and contraction of the compaction oil cylinder; the left and right sides of the casing pipe clamp are provided with a clamping oil cylinder capable of clamping a casing pipe. In working process, through the expansion and contraction of the clamping oil cylinder, and casing pipe can be clamped or unclamped. A piston rod of the compaction hydraulic oil cylinder is extended out through a hydraulic control device, so as to push the outer tube set together with the casing pipe clamp to move downwards; as the oil cylinder is high in thrust, a pin of the casing pipe can be easily and fast pressed into a covering layer on a riverbed, and is accurate to position and difficult to shift. When the casing pipe is lifted, the piston rod of the compaction oil cylinder retracts; as the oil cylinder is also high in tension, the casing pipe can be easily and fast lifted out of the covering layer on the riverbed. The device can greatly raise the work efficiency and operation safety of casing pipe compaction.
Description
Technical field
The utility model relates to a kind of cover tube clamp device of rig, particularly relates to a kind of cover tube clamp device of sailing course drill.
Background technology
Sailing course drill is widely used in the shot hole Drilling of Underwater Engineering reefs such as rivers navigation channel, coastal waterway and port and pier construction.In the work progress of sailing course drill boring,, need unload, transfer, compress and promote sleeve pipe for the location of holing, filling explosive and pressure big gun hole.It is to compress and locating sleeve by tension weight churning that traditional sleeve pipe compresses, and makes sleeve pipe compress into the riverbed, and the slow and dangerous property of speed need be used crane when promoting sleeve pipe, greatly reduces the operating efficiency and the safety of construction of rig.
The utility model content
The technical problem that the utility model need solve is: compress the deficiency of mode inefficiency, safety shortcoming at traditional sleeve pipe, and provide a kind of hydraulic way that adopts to carry out the device that sleeve pipe compresses.The technical scheme that the utility model adopted: this sailing course drill cover tube clamp device comprises drilling cramp, compressed oil cylinder is installed on the drilling cramp, compressed oil cylinder and interior pipe group are joined, the outside of interior pipe group is connected to the outer tube group, on the outer tube group clamp sleeve is installed, clamp sleeve can move up and down with the flexible of compressed oil cylinder; But the clamping cylinder of gripping sleeve is equipped with in the left and right sides of clamp sleeve.
What install on the above-mentioned outer tube group is two cover clamp sleeves up and down.
The beneficial effects of the utility model: clamp or unclamp sleeve pipe by stretching of clamping cylinder, move up and down sleeve pipe, make sleeve pipe can easily be pressed into or extract the riverbed apace, can increase work efficiency greatly and processing safety by the flexible of compressed oil cylinder.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a lateral view of the present utility model;
Fig. 3 is a vertical view of the present utility model.
The specific embodiment
See also Fig. 1-Fig. 3, the utility model sailing course drill cover tube clamp device comprises drilling cramp 1, compressed oil cylinder 2 is installed on the drilling cramp 1, compressed oil cylinder 2 joins with interior pipe group 3, the outside of interior pipe group 3 is connected to outer tube group 4, clamp sleeve 5 is installed on the outer tube group 4, and clamp sleeve 5 can move up and down with the flexible of compressed oil cylinder 2; But the clamping cylinder 6 of gripping sleeve 7 is equipped with in the left and right sides of clamp sleeve 5.
In order to make work firm, what install on the outer tube group 4 is two cover clamp sleeves 5 up and down.
In the course of work, flexible by four clamping cylinders 6 on the two cover clamp sleeves 5 up and down can clamp or unclamp sleeve pipe 7 respectively, the sleeve pipe and help sleeve pipe of conveniently unloading.When many sleeve pipe contact riverbeds that connect needed clamp sleeve, four clamping cylinders 6 on the two cover clamp sleeves 5 stretched out simultaneously up and down, and gripping sleeve 7 can increase clamping force.By hydraulic control device the piston rod that compresses hydraulic jack 2 is stretched out, promote outer tube group 4 and on two cover clamp sleeves 5 move down, because of cylinder thrust is very big, thereby make the sleeve pipe pin can easily be pressed into covering layer on the riverbed apace, accurate positioning is not easy displacement.The piston rod of compressed oil cylinder 2 withdrawal when promoting sleeve pipe, because of the oil cylinder pulling force is also very big, the covering layer that can easily propose sleeve pipe 7 on the riverbed apace.
The utility model following obvious advantage of having compared with traditional version:
1. reduce operating personnel's labour intensity, increase work efficiency and security.
2. thrust is big, makes sleeve pipe press to such an extent that more go deep into cover layer on the riverbed, and the sleeve pipe positioning stablity is reliable.
3. lifting force is big, can be easily rapidly the cover layer on the sleeve pipe proposition riverbed.
