In order to avoid and overcome the technical problem who exists among the prior art, the utility model provides a tube seat structure of hydraulic system pipeline for dam, the utility model discloses can make the orderly emission of oil pipe in the pipeline, be convenient for look for the maintenance to oil pipe also can resume original position after the maintenance, swift high-efficient.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a pipe groove structure of a hydraulic system pipeline for a dam comprises an upper shell and a lower shell which can be enclosed to form a channel for an oil supply pipe to pass through a pipe body, wherein a semicircular guide groove which is coaxial with the channel is arranged in the upper shell or the lower shell;
the rotary table is arranged coaxially with the guide groove and is connected in the guide groove in a sliding mode, and a bayonet for clamping the oil pipes is formed in the outer edge of the rotary table, so that the oil pipes are distributed in the channel along the circumferential direction of the rotary table.
As a further aspect of the present invention: the bayonets are U type groove structures that groove length direction and passageway axis are parallel to each other, and each bayonet socket evenly arranges along carousel circumference.
As a further aspect of the present invention: the guide groove is of a T-shaped groove structure, and the outer edge of the rotary disc is of a T-shaped block structure matched with the guide groove.
As a further aspect of the present invention: the upper shell and the lower shell are both of semicircular shell structures, and the joints of the upper shell and the lower shell are connected with each other by bolts and nuts.
As a further aspect of the present invention: this structure still includes the locking Assembly who restricts the carousel pivoted when two bodys separate, locking Assembly is including seting up the spout of casing closing in the department under, the axis of casing under the groove length direction of spout is perpendicular, and sliding arrangement has the slider in the spout, and the front end roll-off spout of slider forms the grafting cooperation with the lockhole of seting up on the carousel outer fringe face, goes up and arranges the drive block that promotes the slider and retract when two bodys merge on the position that casing closing in the department corresponds.
As the utility model discloses further scheme again: the both ends of spout have been arranged the tang step, and inboard tang step department of being close to the carousel sets up the guiding hole that axial and spout groove length direction are parallel, and the spring bolt of arranging at the slider front end passes the guiding hole and inserts in the lockhole.
As the utility model discloses further scheme again: the upper end face of the sliding block is provided with a V-shaped driving groove, the length direction of the groove is perpendicular to the length direction of the sliding groove, a return spring for pushing the lock tongue to be inserted into the lock hole is compressed between the tail end of the sliding block and a spigot step on the outer side of the sliding groove, and the driving block and the sliding block are arranged in a staggered mode so that the driving block can push the lock tongue to retract when sliding relatively along the groove wall of the driving groove.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses the equipment mode of casing can be when the installation or carry out oil pipe's maintenance about using, and convenient to detach need not insert oil pipe to the other end from the one end of pipeline, perhaps drags oil pipe out from the pipeline when the maintenance, very big improvement the efficiency of work. The rotary table is arranged on the shell in a sliding mode, the oil pipes are clamped in the clamping ports, when maintenance is needed, the corresponding oil pipes can be taken out after being rotated to the corresponding positions, the operation is fast and convenient, the oil pipes cannot be wound in disorder, and the neatness of the distribution of the oil pipes is improved.
2. The utility model discloses use the bayonet socket of U type slot form to the width of notch is less than the width of tank bottom, can be stable like this with the oil pipe joint on the carousel. When the upper shell and the lower shell are closed, the inner wall of the shell can be blocked at the notch, so that the oil pipe is further limited to slide out of the bayonet, and the stability of the oil pipe in the pipeline is ensured.
3. The utility model discloses the locking Assembly who sets up can be when maintaining oil pipe, can be fixed with the carousel, avoids oil pipe to rotate at the in-process of maintenance, leads to the maintenance increase consuming time.
4. The cooperation of the slide block and the return spring can enable the spring bolt to be inserted into a lock hole formed in the outer edge of the turntable, so that the rotation of the turntable is limited. The driving block and the sliding block are arranged in a staggered mode, so that the driving block pushes the lock tongue to retract when sliding motion is generated along the groove wall of the driving groove, when the upper shell and the lower shell are covered, the locking effect of the lock tongue is relieved, the rotary disc can rotate freely, and the change freedom is provided for the oil pipe position caused by continuous oil supply or vibration of the oil pipe in the using process.
