One-way mud scrapping device for reciprocating lifting driven by track rope of

underground water sump

TECHNICAL FIELD

The invention relates to a coal mine underground water sump dredging equipment, in

particular to an one-way mud scrapping device for reciprocating lifting driven by track rope

of underground water sump, which changes the traditional water sump cleaning method to

achieve the effect of underground water sump cleaning without digging, and belongs to the

field of coal mine water sump cleaning technology.

BACKGROUND

In the process of coal mine construction and production, mine water is produced at all

times. The water sump is the place where the drainage wastewater of mine water is stored,

and there will be many mud and coal slimes in the water sump. Long-term storage will

increase the water level of the water sump and reduce the safety of the coal mine water

sump. Therefore, the mud cleaning of the water sump is a key link in the safety guarantee

of the mine. Coal mine water sump cleaning equipment is an efficient and stable equipment

to deal with the mud of the water sump. Because the water sump is hundreds of meters

below the ground, it is closely combined with coal mining, mining and transportation.

Therefore, the cleaning of the water sump is not simply cleaning the mud, but combined

with the cleaning, processing and transportation of coal slime and other links to work

together to form a complete and efficient system. During the working period of the water

sump, the domestic coal mines can not clean up the mud in the water sump. Once the rainy season comes, the water sump is not allowed to stop working, and the mud in the water sump is too much, resulting in the reduction of the safety factor of the coal mine water sump, which will increase the risk of coal miners and their property safety.

The invention patent of "Method and equipmentfor continuous cleaning of central

water sump in underground coal mine without stopping water" with the public number

CN104728310A, which adopts coal sludge sedimentation experiment to determine the

sedimentation length of central water sump in underground coal mine, and then adopts mud

scrapping mechanism at the bottom of the water sump through the track installation

method, as well as transferring the power wire rope and guiding wheel set module, the

reciprocating motion cannot organize the coal mud to gather in the same direction because

the mud scrapping mechanism has been below the water surface during the reciprocating

motion.

The inventionpatent of CN171210683203.4, "Continuous automaticdredgingsystem

under the water body of underground oversized water sump", has an explosion-proof

mobile mud collection device for the mud scrapping mechanism, which includes a mud

collection trolley and a transmission work platform, and the control platform and the work

platform use a motor drive device to drive the chain to make the work platform move

forward. The control platform and the working platform use the motor drive device to drive

the chain, so that the working platform moves forward, and the control mode is realized by

the automatic operation mode to start and stop each part, which is not widely applicable

because the equipment is too big and not easily suitable for the coal mine water warehouse

environment.

The invention patent No. CN103669538 discloses A rope-driven monorail crane

system, including winch, wire rope tensioner, tail device, suspension track, train set, wire

rope and tail wheel. This system is powered by winch, tensioned by the tension device, and

retracted by the cab and rope storage device set on the frame. Multiple sets of cable limiting

components are fixedly connected with the suspension track. The tail cable of the return

rope wheel installed in the rail device passes through the power system and tension device.

For a certain range of slope, monorail crane plays an important role in the safe production

process. Because of the inherent reliable braking performance of monorail crane, it is

generally applicable to the coal mine transportation system, but it cannot be applied to the

requirement of coal slurry transportation or cleaning in the water tank.

In the previous patents and papers, commonly studied are based on the design in the

case of water bunker shutdown, the use of water bunker cleaning equipment to clean the

silt at the bottom of the water bunker, or set to track at the bottom of the water bunker. In

the water bunker cycle reciprocally moving mud scrapping device, or the use of coal sludge

cleaning equipment to clean the sludge of the water bunker after the water bunker shutdown

will cause the water bunker to stop running, its program manual labor intensity, also

suitable for coal mine water bunker environment, the use of too much electrical equipment

in the water bunker there is a certain problem of safety risks; or the system studied can not

be effectively applied to the environment at the bottom of the water bunker, its applicability

is not wide enough.

SUMMARY

The specific technical problem to be solved by the invention is to improve the defects

of the existing structure of the mud scrapping device of the underground water sump, adopt

no electrical setting in the water sump to meet the explosion-proof requirement of the

underground coal mine, adopt the continuous operation structure of the mud scrapping

mechanism, and combine the driving technology and characteristics of the rope traction

monorail crane to provide one-way mud scrapping device for reciprocating lifting driven

by track rope of underground water sump.

The invention is realized by adopting the following technical scheme.

A one-way mud scrapping device for reciprocating lifting driven by track rope of

underground water sump, including hydraulic winch 1, wire rope tensioning vehicle 2,

reciprocating mud scrapping mechanism 3 and return rope device 4; Its characteristic is as

follows:

The reciprocating mud scrapping mechanism adopts a monorail trolley to be installed

on a suspension light rail track and can slide left and right, and two ends of the monorail

trolley are respectively provided with a pair of limiting wheels to limit the movement of

the monorail trolley in the transverse direction and determine the running direction of the

monorail trolley; the monorail trolley and the frame are hinged with each other through a

connecting seat which is connected with the frame together. The monorail trolley is

connected with the mud scrapping frame reliably and has good stability.

The reciprocating mud scrapping mechanism is set between the first cylinder brake

and the second cylinder brake which are distributed at both ends of the roadway, the

monorail trolley and the frame are hinged together by the monorail crane connecting seat, and the frame is connected to the mud scrapping plate by the rotating shaft; The upper end of the scraper is hinged by the adjustable positioning connecting rod and the rotating shaft;

The hanging ring screw is installed at the middle position on both sides; The lifting wire

rope is hinged on the hanging ring screw; The wire rope wheel moves up and down by

lifting the wire rope and lifting the hanging ring screw; The lower end of the scrapping

plate is connected with a mud scrapping rake; And a pair of walking wheels is installed on

the mud scrapping rake (14); The reciprocating mud scrapping mechanism can realize

braking at both ends, and has a simple structure, which can effectively reduce the risk of

explosion accident in coal mine water sump.

The hydraulic winch is used as a power source to drive the wire rope and frame of the

whole system to move forward or backward, and the wire rope tensioning vehicle is used

in cooperation with the winch.

In the above scheme, the reciprocating scrapping mechanism is driven by front and

rear driving wire ropes. The wire ropes are oriented by a guide wheel set to facilitate stress

and guidance. The wire ropes are connected with a driving rack to transmit power and

torque through the cooperation of the driving gear and the driving rack. The speed is

increased and the torque is reduced through a backstop spur gear speed increaser, and the

transmission speed and torque of the output shaft are finally transmitted to the wire rope

pulley, thus lifting the scrapping rake. The guide wheel base for installing the guide wheel

set is installed on the frame through bolt positioning connection.

In the above scheme, the frame is connected by square steel welding positioning, with

lower and upper bottom plates, first and second side plates at the front and rear, and no side

plates at the left and right ends, so that the front drive wire rope and rear drive wire rope can extend from the two ends without side plates and make corresponding actions. The upper bottom plate is positioned and connected to the whole frame, and the four lower bottom plates are positioned and connected to the frame by welding, and play the function of supporting all the internal overall structure; the frame as the main structure support, the first side plate and the second side plate are installed on both sides of the frame by welding positioning connection, and two pairs of bearings with diamond seat will output shaft and drive shaft by positioning connection to fix the first side plate and the second side plate.

The position of the scrapping plate and the frame can be determined by the positioning

hole on the positioning connecting rod, which can adjust the whole length of the scrapping

plate and adjust the angle between the scrapping plate and the horizontal position.

The rotating shaft is connected with the scrapping plate to move up and down through

a positioning connecting rod, and the included angle between the lifting angle and the

horizontal plane is from 7 degrees to 40 degrees; and the walking wheel on the scraper

harrow is driven to follow along with the reciprocating scrapping mechanism in the water

sump roadway, and prevents the scraper harrow from contacting the ground.

In the above scheme, the driving part of the frame adopts the structural design of wire

rope traction gear rack, and the front driving wire rope and the rear driving wire rope used

for driving both ends limit the traction position and direction of the wire rope by

determining the traction direction of the wire rope; One end of the front driving wire rope

and the rear driving wire rope are fixed on the driving rack for installation. The installation

base of the driving rack is composed of channel steel, adjusting base plate, linear guide rail

and linear slide block set. The spring pressure brake, the channel steel connecting lower bottom plate is composed of inclined gasket bolt set, and the edge of the rack is connected with a stop rod by welding.

In the above scheme, the linear slider assemblies are uniformly distributed and

installed under the driving rack, and can move on the linear guide rail with a fixed stroke.

The rack is linearly engaged with the driving gear, which is coaxial with the input shaft of

the backstop spur gear speed increaser, the output shaft is installed on the side plates on

both sides through bearings with diamond seats, and the outermost connector is the driving

wire rope pulley, which can realize the lifting of the mud scrapping plate.

The spring pressure brake is installed under the driving rack and consists of a rotating

block, a spring brake base, a spring assembly, a braking finger, a spring strut and a stop

block, wherein the spring strut, the spring assembly and the brake finger are assembled

together and rotate around the stop block, and the stop block limits the stop rod. When it is

necessary to scrape mud, the roller of the two-way backstop is not limited, and the mud

scrapping mechanism is lowered by its own weight; When mud scrapping is not needed,

the rollers of the two-way backstop are reversely limited, the wire rope drives to lift the

mud scrapping mechanism, and the spring brake will be used for locking to ensure that the

mud scrapping mechanism will not fall off when the reciprocating mud scrapping

mechanism moves to the right end due to its own weight.

Preferably, the core of the reciprocating unidirectional mud scrapping part of the

present invention is a speed increaser, which is a bidirectional backstop applied to the input

shaft. In the above scheme, there are two brakes at both ends of the operating system, which

are fixed at two terminal positions of the water tank and divided into a first brake and a

second brake. Two guide shafts are installed on the brake positioning block, which are used together with the cylinder mounting base. The front end nut of the cylinder is clamped between the cylinder driving end platen and the cylinder driving end top plate, and the brakes brake Its braking mechanism is simple, stable and reliable, which can overcome the unstable situation driven by a single wire rope, make the mud scrapping mechanism in the water sump more compact and simple, and realize the functions of braking, lifting and lowering of the mud scrapping mechanism with the driving part of the reciprocating mud scrapping mechanism.

The hydraulic winch and the rope return device are used as power sources to drive the

wire ropes of the whole system to move forward or backward, and the wire rope tensioning

vehicle is used in cooperation with the winch, so that all the wire ropes on the system can

be tensioned on the wire rope tensioning vehicle, so that the system runs smoothly and the

driving safety of the whole system is ensured.

The rotating speed of the hydraulic winch is 12r/min, the moving speed of the

monorail crane is 2.4m/min, and the daily average cleaning amount of sludge in the water

sump can reach 50-1OOm 3 .

Compared with the prior art, the patent application has the following advantages and

effects:

The invention designs and manufactures a scraper driven by rope traction. The

mechanism uses a wire rope to drag a rack to drive a gear to input torque, and the output

shaft drives a lifting wire rope pulley to lift the scraper. When the stroke starts, the backstop

is released, the brake is locked, and the driving wire rope will lower the scrapping plate.

After the brake is released, the reciprocating scraper runs to the left end as a whole, and the

scrapping rake is placed at an appropriate angle to clean the sludge at the bottom of the water sump, reaching the first brake after reaching the leftmost end. The mechanism adopts pure mechanical design, which can output linear motion into rotation at an appropriate position and achieve the automatic lifting function of the scraper.

Secondly, the invention is designed to clean the coal slime at the bottom of the coal

mine water sump by combining the auxiliary equipment of the coal mine rope traction

monorail crane and the mud scrapping mechanism, which has the advantages of being

adaptable to the complex and changeable environment of the water sump roadway, having

a wide application range, being able to stop braking in time and ensuring the operation

safety of the mud scrapping mechanism.

Finally, that invention provide a set of continuous operation mode of the water sump

without stop working. The mechanism adopts a monorail crane and its auxiliary devices

which are installed on the rock wall at the top of the water sump, and the monorail crane is

connected with a reciprocating mud scrapping mechanism, and the reciprocating mud

scrapping machine drives a mud scrapping mechanism to clean mud at the bottom of the

water sump back and forth in one direction, and concentrates coal slime at one end of the

water sump, and adopts coal slime cleaning equipment to clean the coal slime. The

reciprocating cleaning equipment for the underground water sump adopts the passive

driving device of the underground water sump, which is driven by a steel wire rope to

reduce the safety risk of coal mines.

CN1093831C and titled "Continuous Tractor"; The suspended light rail track 7 can refer

to the suspended light rail track in CN103669538A, the composition of its front-rear

connection mode and the installation method of the track main body, or refer to the standard

of the track suspended track in the book "MonorailSuspension System Scheme Design".

As shown in Fig. 3 to Fig. 5, the reciprocating scrapping mechanism 3 is driven by a

front driving wire rope 28 and a rear driving wire rope 26. The wire ropes are oriented by

a guide wheel set 27 to facilitate stress and guidance. The wire ropes are connected with a

driving rack 20, which transmits power and torque through the cooperation of the driving

gear 20 and the driving rack 21, increases the rotation speed and reduces the torque through

a backstop spur gear speed increaser 23, and finally transmits the transmission speed and

torque of the output shaft 22 to a wire rope wheel 33, thereby lifting the scrapping rake 14.

The guide wheel base 29 for installing the guide wheel set 27 is installed on the frame 16

through bolt positioning connection. The wire rope drives are respectively located at both

ends of the frame 16, and cooperate with the frame 16 and the monorail trolley 17 to move

back and forth. The monorail trolley 17 is hung on the suspension light rail track 7,

symmetrically arranged at both ends, and directly connected with the monorail crane base

9 through the positioning connection holes on the monorail trolley 17. There are four

monorail crane bases in two pairs, and each pair is directly symmetrically installed on the

monorail trolley 17. The monorail trolley 17 is provided with a limiting wheel to limit the

left and right swing of the monorail trolley 17, and the limiting wheel is positioned at the

lower end of the suspended light rail track 7. When driving, the front driving wire rope 31

is paid out by the hydraulic winch 1, the tension of the front driving wire rope 28 is

determined by the wire rope tensioning vehicle 2, and then the reciprocating mud scrapping

mechanism 3 is driven to run by the guide wheel set 27; The front driving wire rope 31

extends out from the left end of the frame, and then the connecting strip is located at the

right end of the running system when the whole mud scrapping mechanism 3 is located at

the right end of the frame, and the mud scrapping plate is not lowered because the driving

rack 20 is also located at the right end of the frame.

As an implementation, the monorail trolley 17 is installed in such a way that the

monorail trolley 17 can press the suspension light rail track 7 under the gravity of the whole

suspension device, so that no additional power device is needed, and the trolley wheels 18

can roll on the suspended light rail track 7 by friction.

As shown in Fig. 3, the positions of the scrapping plate 19 and the frame 16 can be

determined by the positioning holes on the positioning link 10, which can adjust the overall

length of the scrapping plate and adjust the angle between the scrapping plate 4 and the

horizontal position. The rotating shaft 30 is connected with the scrapping plate 19 through

the positioning connecting rod 10, and the scrapping plate 19 moves up and down around

the rotating shaft 30 in a proper range, and the angle formed by the scrapping plate and the

horizontal position ranges from 7 to 40 degrees. The traveling wheel 13 on the scrapping rake 14 can walk along with the reciprocating scraper mechanism 3 in the water sump roadway, and prevent the scrapping rake 14 from directly contacting the ground. The scrapping plate 19 is welded by square steel and angle steel, and has an open upper end.

The scrapping plate 19 integrally rotates around the rotating shaft 30 on the frame 16, and

the rotating shaft 30 is installed on the side plates at both ends of the frame 16 by bearings

31 with diamond seats.

As an implementation mode, the suspension light rail track 7 is an I-shaped guide rail,

and the upper end of the I-shaped track is provided with a connecting lug matched with the

anchor rod assembly 5, while the bottom end is provided with an embedded groove and a

matching block used for connecting I-shaped materials to form a buckle form, and the

anchor rod assembly 5 is connected with the connecting lug at the upper end of the I-shaped

track and installed on the top of the water storage roadway 6, so that the suspension light

rail track 7 can be connected in front and back.

As shown in Fig. 4 to Fig. 5, the front driving wire rope 28 and the rear driving wire

rope 26 used for driving two ends limit the pulling position and direction of the wire ropes

by determining the pulling direction of the wire ropes, and one end of the front driving wire

rope 28 and the rear driving wire rope 26 are fixed on the driving rack 20 for installation,

and the installation base of the driving rack 20 is composed of a channel steel 36, an

adjusting base plate 24, a linear guide rail 32 and a linear slider group 26, and the spring

pressure brake 35 is connected with the lower bottom plate 40. The edge of the rack is

connected with a stop rod 25 by welding; The front drive wire rope 28 and the rear drive

wire rope 26 are connected with the drive rack 20 in the middle, and the other end of the

front drive wire rope 28 passes through the guide wheel set 27. The same applies to the rear drive wire rope 26. As the guide and bearing part of the wire rope, the wire rope can pass between its hub and the locating pin shaft, and can be pulled and translated on the rubber outer ring of the guide wheel set 27.

As an implementation, the linear slider assemblies 34 and the linear guide rails 32 are

installed on the adjustment pad 24 on the channel steel 36, which is connected to the base

mounting plate of the frame 16 by using oblique gaskets. There are four linear slider

assemblies 34, which can stably bear the load of gear rack meshing on their guide rails.

on the square steel 38 at the front and rear ends of the frame to respectively position and

connect the guide wheel base 29 and the monorail crane connecting base 9.

As shown in Fig. 7 to Fig. 8, the first cylinder brake 8 and the second cylinder brake

15 are provided with a cylinder mounting base 43 in the middle of the brake positioning

block 46, and the mounting nut at the other end of the piston rod on the standard cylinder

48 is pressed between the cylinder driving end top plate 49 and the driving end pressure

plate 45. when the standard cylinder 48 is driven forward, the guide shaft 44 plays a role

in positioning and guiding the standard cylinder 48 and the cylinder driving top plate 49.

The brake connecting lug 47 is welded and installed on the frame 16, and is connected with

the brake block 46 on the cylinder brake after the wire rope pulls the frame 16 to the

designated position of the water bin; The brake lever 50 of the brake pushes forward under

the action of the standard cylinder 48, and then is connected with the brake block 46, and the whole cylinder brake can brake the reciprocating mud scraping mechanism 3 at this time.

As shown in Fig. 9, the spring pressure brake 35 is installed on the bottom plate of the

frame 16, the spring brake base 52 is connected with the bottom plate by bolts, and the

rotating block 51 is used in cooperation with the limiting block 56, so that the spring

assembly 53, the spring strut 55 installed on the rotating block 51 and the braking finger

54 can rotate around the rotating block 51 at a certain angle. When the gravity of the scraper

plate 19 and the pulling force brought by the wire rope are transmitted to the rack and

pinion, the stop rod 25 on the driving rack 20 is forced to act on the spring pressure brake

35, and the spring brake 35 can be opened when its pressure is greater than the opening

pressure of the brake finger 54 on the spring brake 35. At this time, the stop rod 25 can

pass through the spring brake, and the scraper plate 19 can also be lowered to clean the

sludge at the bottom of the water tank. When the reciprocating mud scraper mechanism 3

is located at both ends of the water bin, the stopper rod 25 is only affected by the gravity

of the mud scraper plate 19, and the pressure caused by it cannot open the spring brake 35,

and then the mud scraper plate will not be lowered.

The above is only a preferred embodiment of the present invention, and is not intended

to limit the protection direction of the present invention. Any modifications, equivalent

substitutions and improvements made within the spirit and principles of the present

invention are included in the protection scope of the present invention.
