Description

[Detailed description of the invention] The present invention relates to a traveling pump type sand suction device equipped with a telescopic guide frame, and particularly relates to a traveling pump type sand suction device with a pump guide rail, which is equipped with a pump guide rail within the telescopic guide frame. It is something.

Conventionally, a sedimentation basin has a running trolley that runs on rails installed on both sides of the sedimentation tank bottom, a transverse trolley that runs on this running trolley, and a sand suction pump that is raised and lowered by a winding device installed on the transversal trolley. A traveling pump type sand suction device has been developed that sucks up sand accumulated on the pond bottom by moving the sand suction pump vertically and horizontally.

However, this device has a structure in which the sand suction pump is suspended from a traversing cart using a wire rope or the like, and therefore, if the sand at the bottom of the pond is uneven, the sand suction pump tilts and becomes unable to suck sand.

Therefore, by providing a telescopic guide frame that guides the sand pump suspended from the top of the traversing cart, the sand pump does not tilt even if the sand at the bottom of the pond is slightly uneven.A traveling pump type with a telescopic guide frame. A sand absorbing device was devised.

However, when a submersible sand pump moves up and down inside a telescopic guide frame, if the pump shakes or the guide frame is slightly inclined, the pump gets caught on the iron material that makes up the guide frame, making it impossible to move up and down smoothly. .

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a traveling pump type sand suction device with a pump guide rail in which an ice sand suction pump moves up and down smoothly within a telescopic guide frame.

According to the present invention, the above object is remotely achieved by providing a guide rail within a telescopic guide frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a traveling pump type sand absorption device with a pump guide rail according to the present invention will be described below with reference to the drawings.

1 and 2 are diagrams showing a traveling pump type sand suction device with a telescopic guide frame, which is an embodiment of the present invention.

Rails 1 are installed on both sides of the sedimentation tank 14 separated by a partition wall 12.
6 is laid out.

A traveling body saddle 18 having wheels is placed on this rail 16, and a pair of traveling body girts 20 are provided on this traveling body saddle 18 so as to cross the sedimentation basin 14 to form a traveling carriage.

A pair of traversing rails 22 are laid on this traveling body gutter 20, and a traversing truck 26 having wheels 24 is placed on these traversing rails 22.

A water distribution trough 28 is installed on the outside of one of the transverse rails 22 along the rail 22 so as to be inclined.

The lower end of this water distribution trough 28 extends to the top of a sand settling machine 30 installed on the floor outside the rail 16.

A traveling device 32 for moving the traveling body saddle 18 is provided at the center of the outside of the other traversing rail 22, and its power is transmitted to the wheels of the traveling body saddle 18 via a drive shaft 34.

A wire rope 40 for suspending a traversing device 36 for moving the traversing truck 26 and a submersible sand suction pump 38 suspended from the bottom of the traversing truck 26 to the bottom of the sedimentation tank 14 is wound onto the traversing truck 26, and a wire rope 40 is wound around the traversing truck 26 to suspend the submersible sand absorption pump 38, which is suspended from the bottom of the traversing truck 26 to the bottom of the sedimentation tank 14. A winding drum 42 that raises and lowers the pump 38 and a winding device 44 that drives this winding drum 42
is provided.

Furthermore, a hydrocyclone 46 and a driver's cab 48 are provided on the traversing truck 26 to condense the sand water sucked up by the submersible sand pump 38 and to flow out into the water distribution trough 28.

A telescopic guide frame 50 is provided at the lower part of the traversing truck 26 to guide the submersible sand pump 38 suspended therefrom.

This telescopic guide frame 50 is composed of a fixed frame 52 suspended from the traversing truck 26, and a movable frame 54 that can move up and down within this fixed frame 52.

A guide rail (see FIG. 3) is provided within the movable frame 54 on which the submersible sand absorption pump 38 slides up and down.

Note that this movable frame 54 is attached to a sling chain (fifth
(see figure).

Figures 3 and 4 show guide rails mounted within the movable frame at the bottom of the telescopic guide frame.

However, similar or identical components to those in FIGS. 1 and 2 are indicated using the same reference numerals.

Guide rails 56 having a U-shaped cross section are linearly attached to the four corners of the movable frame 54.

Four square guide legs 58 that slide on this guide rail 56 and guide the submersible sand pump 38 are connected to a leg fixing band 60.
is fixed to the outer periphery of the submersible sand pump 38.

Next, the operation of this device will be explained using FIGS. 5 to 7.

As shown in FIG. 5, a submersible sand absorption pump 38 is suspended by a wire rope 40 hanging from a winding drum 42 provided on the traversing truck 26.

This wire rope 40 is a telescopic guide frame 50.
A movable frame 54 constituting the lower part of the frame is also suspended via a sling chain 62.

When the winding drum 42 rotates in the direction of the arrow in the figure, the movable frame 54 rises within the fixed frame 52, resulting in the state shown in FIG. 6.

After completing the ascent, the traversing truck 26 moves and crosses the bulkhead 12.

Next, the winding drum 42 is reversely rotated, the movable frame 54 is lowered, and sand absorption work can be started.

When hoisting only the submersible sand pump 38, move the movable frame 54 up to the position shown in FIG.
4 with a stopper 64.

Then, by removing the sling chain 62 and further rotating the winding drum 42, the submersible sand absorption pump 38 can be wound up along the guide rail 56 in the movable frame 54, as shown in FIG. I can do it.

In addition, in order to return the submersible sand pump 38 to the pond bottom, the operation described above may be reversed.

According to this embodiment, when a foreign object that prevents the rotation of the pump disturbance blade becomes entangled, or when replacing the discharge hose or the submersible sand suction pump 38, the submersible sand suction pump 38 is moved to the movable frame of the telescopic guide frame 50. 54, the submersible sand pump 38 rises along the guide rail 56, so the guide frame 50 may be slightly inclined or the submersible sand pump 3
Even if the submersible sand suction pump 38 shakes, it will not get caught on the guide frame 50, and the submersible sand suction pump 38 can be smoothly raised and lowered.

As is clear from the above explanation, according to the present invention, by providing a guide rail within the telescopic guide frame, the submersible sand suction pump can move smoothly up and down within the telescopic guide frame. Sand equipment can be provided.
