Description

[Detailed description of the invention] The present invention relates to a traveling pump type sand absorbing device equipped with a telescopic guide frame, and particularly relates to a traveling pump type sand absorbing device with a telescopic guide frame that can detect the inclination of the telescopic guide frame. It is.

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

However, since this device has a structure in which the sand pump is suspended from the top of the traversing truck using wire lobes or the like, there is a drawback that if the sand at the bottom of the pond is uneven, the sand pump will tilt and become unable to suck sand.

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

However, if a telescopic guide frame is adopted and it has a fixed structure, if the guide frame hits an extremely accumulated part of the sand pile at the bottom of the pond and an excessive force is applied to the lower end of the frame, the traversing trolley will The disadvantage is that the rails may float off the rail or fall over.

In view of the above-mentioned drawbacks, the purpose of this invention is to prevent the slipping of the wheels of the traversing truck and the overturning of the traversing truck when excessive force is applied to the telescopic guide frame. We are here to provide you with the equipment.

The above object of the present invention is to provide fulcrums of elongated holes supporting the telescopic guide frame at the top of both sides in the transverse direction, and to provide levers so as to contact the upper ends of the guide frames on extensions of these fulcrums. This is achieved by providing a limit switch that works in conjunction with the lever, and providing a mercury switch on both sides of the guide frame in the running direction, and detecting the inclination of the guide frame during traversing and when traveling by the limit switch and the mercury switch, respectively. Ru.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the traveling sand absorbing device with a telescopic guide frame according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are diagrams showing a traveling pump sand suction device with a telescopic guide frame according to 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 so as to be inclined along the rail.

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.

On the traversing truck 26, there is a traversing device 36 for moving the traversing truck 26, and a wire rope 40 for suspending a submersible sand absorption pump 38 which is suspended from the traversing truck 26 to the bottom of the sedimentation tank 14.
A winding drum 42 for winding up the submersible sand pump 38 and raising and lowering the submersible sand absorption pump 38, and a winding device 44 for driving the winding drum 42 are provided.

Furthermore, a hydrocyclone 46 and an operator's cab 48 are provided on the traversing truck 26 to condense the sand water sucked up by the submersible sand absorption pump 38 and to flow it out to the water distribution l/rough 28.

A submersible sand pump 3 is suspended from the bottom of the traversing cart 26.
A telescopic force guide frame is provided to guide the 8.

This telescopic force aid frame includes a fixed frame 50 suspended from the traversing trolley 26, and a
It consists of a movable frame 52 that can be moved up and down.

Note that a wall opening 54 is provided in the upper part of the partition wall 12 of the sedimentation tank 14.

The submersible sand pump 38 can be moved to any point in the sedimentation basin 14 by moving the traversing cart 26 and the traveling saddle 18 vertically and horizontally.

Moreover, since the sub-ice sand suction pump 38 is guided by a telescopic guide frame, the sand water is sucked up without being affected by the slight unevenness of the pond bottom, and this sand water is transferred to the hydrocyclone 46 on the traversing cart 26 and the water distribution. The sand is transferred through the trough 28 to the sand settling machine 30 and carried out to the outside.

3 to 6 are diagrams showing the main parts of the traveling sand absorbing device with a telescopic guide frame according to the present invention.

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

Figures 3 and 4 show a detection device when a force is applied to the telescopic guide frame from the transverse direction and the telescopic guide frame is tilted. It is supported by being inserted into the fulcrum 58 of the hole.

An inclination sensing lever 60 interlocked with a limit switch 64 is provided above the fulcrum 58 so that its tip contacts the top of the fixed frame 50.

When the tip of the movable frame 52 hits a sand pile or the like while traversing and receives an abnormal force, the force is transmitted to the fixed frame 50, and the fixed frame 50 is rotated about the fulcrum 58 in the direction of the arrow shown in FIG. In this case, since the fulcrum 58 is an elongated hole, for example, when a force is applied from the left direction in the drawing, the upper right end of the fixed frame 50 moves up.

Conversely, when a force is applied from the right, the left upper end of the fixed frame 50 approaches.

Therefore, the tilt sensing lever 60 also follows the movement of the fixed frame 50 and moves upward in the vertical direction.

Note that the arrows in FIG. 4 indicate the inclination angle of the fixed frame 50.

FIG. 5 shows the tilt sensing lever and the limit switch section, and the end of the tilt sensing lever 60 is in contact with the top of the fixed frame 50 having the fulcrum 58 in the form of an elongated hole.

This inclination sensing lever 60 is bent in a right angle direction and is rotatably supported by a lever fulcrum 62.

The other end of the tilt-sensing lever 60 is in contact with a limit switch 64 .

When the top of the fixed frame 50 rises as indicated by the arrow in the figure, the inclination sensing lever 60 operates and the limit switch 64 is actuated.

FIG. 6 is a side view of FIG. 3 and shows a detection device when a force is applied to the telescopic guide frame from the direction of travel, causing it to tilt. A limit switch 66 made of a mercury switch is installed on the upper side of the fixed frame 50. It is arranged so that it is activated when the fixed frame 50 is tilted in the direction shown by the arrow in the figure.

The limit switches 64 and 66 described above are linked to an alarm device on a driving operation panel, or to the traveling device 32 or the traversing device 36.

If the telescopic guide frame tilts, a warning will be issued or operation will be halted.

According to this embodiment, even if an excessive force is applied to the lower end of the telescopic guide frame and the guide frame is tilted, the operation can be immediately stopped, thereby preventing accidents such as the traversing wheels 24 floating or the traversing cart 26 falling. It is effective in preventing

Since the submersible sand pump 38 can always be used in the vertical direction,
Since sand absorption efficiency is improved and the above-mentioned accidents can be prevented, there is an effect of increasing the operating rate of the entire device.

As an application example of the present invention, the present invention uses a lever-type limit switch 64 as a method for detecting the inclination of the guide frame in the transverse direction, but as shown in FIG. A similar effect can be obtained by touching the top.

To detect the inclination in the traveling direction, a mercury switch 70 (Tilt Switch manufactured by Yamatake Honeywell) is suspended from a rope 72 fixed at one end to the fixed frame 50 as shown in FIG. 8, or a lever method (not shown) is used. ), the same effect can be obtained.

As is clear from the above description, according to the present invention, a fixed frame is provided with an elongated fulcrum, and a pin is inserted into the fulcrum, and a telescopic guide frame is attached to a traversing cart, so that the guide frame can be moved in four directions. (By detecting this inclination with a limit switch, more force than necessary is applied to the telescopic guide frame.)
It is possible to provide a traveling pump type sand absorption device with a telescopic guide frame that prevents the wheels of a traversing truck from slipping and the traversing truck from falling over.
