Referring to fig. 1 to 3, a tunnel trolley drilling drainage recovery device includes a waterproof ring 2 disposed at a feeding end of a drill boom main body 1, a water guide channel 201 is obliquely disposed in a middle portion of the waterproof ring 2, a filter screen 3 is disposed in the water guide channel 201, a water pumping device 4 is connected to a low potential end of the water guide channel 201 on the waterproof ring 2, and the water pumping device 4 is communicated with a water tank through a water pipe 5. The drill boom main body 1 is a push beam 101 of a drill jumbo, a waterproof ring 2 is arranged at the push end of the push beam 101, the middle part of the waterproof ring 2 is a water diversion channel 201 with a certain inclination, a drill rod 102 above the push beam 101 is in the water diversion process, water flow falls into the waterproof ring 2 below, simple filtration is carried out through a filter screen at the end of the water diversion channel 201, and then water drained through a water pumping device 4 at the tail part (namely the low-potential end of the water diversion channel) is conveyed into a water tank prepared in advance through a water pipe 5.

In this scheme, waterproof ring 2 sets up in propelling beam 101 and feeds the below of end department, and the opening on waterproof ring 2 is towards propelling beam 101 of top. Thus, the waterproof ring 2 with the water channel 201 is a trough structure, and the trough structure can receive water falling from the upper part, so that the aim of collecting sewage is fulfilled. Because the water channel 201 has a certain gradient, sewage can flow down conveniently, and the power of the water pumping device 4 can be reduced.

Preferably, the waterproof ring 2 provided with the penstock 201 is a groove body structure with a sector section, one side of a sector 202 of the waterproof ring is detachably mounted on the drill boom main body (the push beam 101) through a connecting piece, and the other side of the sector abuts against the tunnel face 6.

Preferably, the waterproofing ring 2 is made of an elastic material. At this time, the waterproof ring 2 provided with the penstock 201 may also have a groove structure with a semicircular cross section, as shown in fig. 3. Through the inseparable laminating of waterproof ring of elasticity and tunnel face 6, collect water when not influencing the platform truck drilling, can also avoid simultaneously sealing water ring and rock direct contact to cause the damage.

Preferably, the screen 3 is provided on the low potential end side of the penstock 201. The screens may be spaced in two or more layers. After being simply filtered by two layers of filter screens, the filter screen is accumulated in the water diversion canal and finally is drawn out.

In this scheme, the volume of drawing water of pumping device should be no less than the water yield that the water driller produced, can avoid leading to the device to destroy by hoarding too much water in the diversion canal 201 like this. The waterproof ring 2 is connected with the drill boom main body through the fixing support 7 through bolts, and the interior of the waterproof ring 2 can be regularly cleaned by detaching the bolts.

Among this recovery unit, drill boom main part 1 passes through bolt hole and the fixed bolster 7 bolted connection among the recovery unit, waterproof ring 2 is made by elastic material, semicircular in shape or fan-shaped, drilling rod 102 is when carrying out the drilling operation, waterproof ring 2 closely laminates with the rock mass of face 6, form semicircular/fan-shaped region, collect the water that the drilling in-process produced, water in through the inlet channel 201 is under the simple filtration of filter screen 3, temporarily stocked in the inlet channel 201 bottom, carry it in the sump tank of preparing through (small-size) pumping device 4, the sump tank leads to pipe 5 and is connected with pumping device 4.

Because waterproof ring 2 is closely laminated with the face, probably the rubble falls into this recovery unit in drilling process, through dismantling the bolt of fixed bolster 7 with drill boom main part 1, can lift this recovery unit off, removes filter screen 3 and washs, clears up inside inlet channel 201 simultaneously. To prevent debris from falling into the penstock 201, a barrier screen may be placed at the opening of the waterproofing ring 2 (i.e., at the top of the penstock 201).

The implementation method of the device is as follows:

firstly, connecting a drill boom main body 1 with a fixed support 7 of a recovery device through a bolt, driving the recovery device to lean against a face when the drill boom works, and tightly attaching the recovery device with the face through an (elastic) waterproof ring 2; then, the water generated during the drilling process is received by the waterproof ring 2 and guided into the penstock 201, and because the penstock 201 has a certain inclination, the guided water is automatically collected to the bottom of the penstock 201, and is simply filtered by the filter screen 3, and then the water collected to the bottom of the penstock 201 is pumped out by the small-sized pumping device 4, and is then delivered to a prepared water collection tank by the water pipe 5, and finally the water in the water collection tank is reused by the trolley after being treated.

This recovery unit can effectively cooperate the use of platform truck in the tunnel, collects the water that the platform truck produced at the course of the work, purifies the back through filter equipment and finally provides the platform truck water tank recycle, can practice thrift the cost, reduces resource consumption, can also strengthen the sustainable operation of platform truck, improves and lifts car work efficiency.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
