Description

Technical Field

[0001] The invention relates to the technical field of waste transportation, in particular to an automatic transportation and loading device for drilling fluid waste. Background Art

[0002] A large amount of waste oil-based mud is generated during oil drilling. The oil-based mud temporarily stored in the silo needs to be transported and centrally processed at the drilling site. In the existing technical solution, the waste in the silo is lifted up and transported to the vehicle for transportation by using the cooperation of horizontal and inclined augers. However, the mud in the silo is viscous, heavy and has a certain fluidity. If the auger rotates too slowly, the mud will easily slide along the auger. If the auger rotates faster, the blades of the auger will be subjected to excessive force and easily damaged.

[0003] The inventor attempts to utilize a vertically arranged bucket elevator to replace the auger that tilts upwards to carry out the transportation of muddy waste. At this moment, the scraper mechanism of the elevator can prevent the muddy waste from sliding off, and is convenient to utilize each scraper to disperse and bear the weight of the waste.

[0004] However, the height of the bucket elevator is generally large, and its lower end is directly inserted into the silo. When the conveying and loading device needs to be transported between different work sites, it is easy to overturn due to the high center of gravity. In addition, the upper outlet of the elevator is high, and the lower inlet is plugged into the silo. When the scraper in the elevator is damaged or the side wall of the scraper is adhered with mud that is difficult to fall off, it is not convenient to quickly clean and repair and replace the scraper on the elevator. Summary of the invention

[0005] The present invention provides an automatic conveying and loading device for drilling fluid waste, which can solve at least one of the above-mentioned technical problems.

[0006] In order to solve the above technical problems, one or more embodiments of the present invention provide an automatic conveying and loading device for drilling fluid waste, including a silo and a bucket elevator. The upper end of the silo is open, the length direction of the silo is the first direction, and the width direction of the silo is the second direction. The upper part of the silo is provided with a guide rail extending along the first direction, and a slide capable of moving along the guide rail is installed on the guide rail, and the slide has an inner cavity that penetrates itself vertically. Part of the structure of the elevator is inserted into the inner cavity of the slide, and a rotating seat is rotatably installed on the side wall of the slide, and the rotation axis of the rotating seat is parallel to the second direction, and the rotating seat is slidably connected to the elevator. A locking mechanism capable of locking the rotating seat is installed on the side wall of the slide, and the conveying and loading device has a first working state and a second working state.

[0007] In the first working state, the locking mechanism locks the rotating seat, the elevator is arranged vertically, the elevator can be lifted vertically relative to the slide, and the feeding end of the elevator passes downward through the inner cavity of the slide and is supported by the bottom wall of the silo. In the second working state, the locking mechanism unlocks the rotating seat, and the elevator can rotate with the rotating seat, so that the elevator rotates from a vertical arrangement to a horizontal arrangement, and the elevator overlaps the guide rail to achieve self-support.

[0008] The beneficial effects of one or more of the above technical solutions are:

[0009] In this solution, a slide that can move in a first direction is arranged on the silo, part of the structure of the bucket elevator is plugged into the inner cavity of the slide, a rotating seat is installed on the side wall of the slide, and a locking mechanism that can lock or unlock the rotating seat is also arranged on the slide. Then, the elevator in this solution is easy to guide during rotation through the rotating seat. In the first working state, the elevator is arranged vertically and its feed end passes downward through the slide to enter the silo. In the second working state, the elevator is arranged horizontally and supported by a guide rail.

[0010] That is, the bucket elevator in this solution can lift and transport the mud waste in the silo in the first working state. In the second working state, the height of the entire conveying and loading device is lowered to facilitate its transfer between different work sites and reduce the probability of overturning; and in the second working state, the height of the feed end and the discharge end of the elevator is relatively low, which is convenient for maintenance or cleaning of the bucket in the elevator.

DETAILED DESCRIPTION

[0022] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0023] See also Figure 1-Figure 10 A typical embodiment of the present invention provides an automatic conveying and loading device for drilling fluid waste, comprising a silo 1 and a bucket elevator 6. The silo 1 is open at the upper end, the length direction of the silo 1 is the first direction, and the width direction of the silo 1 is the second direction. A guide rail 15 extending along the first direction is provided at the upper part of the silo 1, and a slide 3 capable of moving along the guide rail 15 is installed on the guide rail 15, and the slide 3 has an inner cavity penetrating itself in the vertical direction. The elevator 6 can convey materials along a third direction, that is, the third direction is the feeding direction of the elevator 6. Part of the structure of the elevator 6 is inserted into the inner cavity of the slide 3, and a rotating seat 21 is rotatably installed on the side wall of the slide 3, and the rotation axis of the rotating seat 21 is parallel to the second direction. The rotating seat 21 is slidably connected to the elevator 6, and the sliding direction of the two is parallel to the third direction. A locking mechanism capable of locking the rotating seat 21 is installed on the side wall of the slide 3, and the conveying and loading device has a first working state and a second working state.

[0024] In the first working state, the locking mechanism locks the rotating seat 21, the elevator 6 is arranged vertically, and the elevator 6 can be lifted and lowered vertically relative to the slide 3, so as to adjust the distance between the feed end of the elevator 6 and the bottom wall of the silo 1. The feed end of the elevator 6 passes downward through the inner cavity of the slide 3 and is supported by the bottom wall of the silo 1. At this time, it is convenient to use the elevator 6 to move along the first direction to realize the scraping and lifting of the mud at different positions of the silo 1 by the elevator 6, so as to avoid the slow flow speed of the mud affecting the lifting and transportation efficiency of the elevator 6.

[0025] In the second working state, the locking mechanism unlocks the rotating seat 21, and the elevator 6 can rotate with the rotating seat 21, so that the elevator 6 rotates from a vertical arrangement to a horizontal arrangement, and the elevator 6 overlaps the guide rail 15 to achieve self-support. At this time, the elevator 6 is horizontal, and one end of the slide 3 along the first direction is open, so that the feed end of the elevator 6 is inserted into the inner cavity of the slide 3 from the open position, and the discharge end of the elevator 6 extends in a horizontal direction away from the slide 3. The slide 3 moves to one side of the silo 1 along the first direction, so that the discharge end of the elevator 6 does not exceed the silo 1 along the first direction.

[0026] In this embodiment, the slide 3 has at least two vertically arranged side panels 31, the side panels 31 of the slide 3 are perpendicular to the second direction, and the two side panels 31 are respectively arranged near the two guide rails 15. At least at one end along the first direction, the two side panels 31 are fixedly connected to form a whole by a connecting member 32 such as a rod or a plate. Specifically, the side panels 31 and the connecting member 32 are detachably fixed.

[0027] As a specific structural form, in the first working state, the two ends of the two side plates 31 along the first direction are respectively fixed by the above-mentioned connecting pieces 32 to limit the above-mentioned inner cavity. The elevator 6 is arranged vertically and is limited in the inner cavity. In the second working state, one side of the two side plates 31 along the first direction is still fixed by the connecting piece 32, and the connecting piece 32 on the other side is removed, so as not to affect the horizontal insertion of the feed end of the elevator 6 into the inner cavity of the slide 3.

[0028] In other structural forms, the connecting member 32 is a connecting rod, and the connecting rod is fixed to the lower end of the side plate 31. In the second working state, the feed end of the elevator 6 can be overlapped on the connecting rod of the slide 3.

[0029] In this embodiment, a guide assembly and a lifting drive assembly are installed between the elevator 6 and the slide 3. The lifting drive assembly can drive the elevator 6 to slide relative to the slide 3 along the third direction, and the guide assembly can guide the elevator 6 when sliding. At this time, in the first working state, the elevator 6 is arranged vertically, and the lifting drive assembly and the guide assembly can drive the elevator 6 to rise and fall vertically to change the depth of the elevator 6 entering the silo 1 after extending out of the slide 3.

[0030] Specifically, the silo 1 is square, has a square inner cavity, and the opening at the upper end of the silo 1 is a square opening. At the same time, the length dimension of the silo 1 is greater than the width dimension and the height dimension. The length of the silo 1 is greater than the height of the elevator 6 along its own conveying direction. In this arrangement, when the elevator 6 is in a horizontal state, it still does not exceed the silo 1 in the first direction, so as to reduce the probability of the elevator 6 being hit during the transportation process.

[0031] In this embodiment, there are two guide rails 15, which are arranged side by side along the second direction, and the guide rails 15 are fixed to the upper end surface of the silo 1 by welding or bolting. In addition, the two ends of the guide rail 15 protrude from the two ends of the silo 1 along the first direction, so as to prevent the slide 3 from falling out of the guide rail 15 when moving along the first direction.

[0032] It should be noted that the working principle and most of the structure of the bucket elevator are existing technologies. Figure 2 The bucket type elevator 6 in this embodiment includes a shell 63, a fixed frame 62 is arranged in the shell 63, and the fixed frame 62 is fixed to the inner wall of the shell 63. A belt-type or chain-type closed loop conveyor line for conveying along the third direction is arranged in the inner cavity of the shell 63. A plurality of scrapers 61 are sequentially installed on the outer peripheral contour of the conveyor line. Among them, the conveyor line is supported by the fixed frame 62, and the fixed frame 62 protrudes from the conveyor line so that the fixed frame 62 contacts the bottom wall of the silo 1, thereby achieving self-support. When in use, the scraper 61 does not contact the bottom wall surface of the silo 1, thereby avoiding the scraper 61 and the conveyor line from contacting the bottom wall of the silo 1 and affecting the operation. Specifically, a reduction motor 8 is installed on the upper end of the shell 63 in the elevator 6 through a mounting frame 7, and the output shaft of the reduction motor 8 is coaxially fixed with the driving wheel 17 located above in the conveyor line.

[0033] In this embodiment, a first auger 16 for feeding materials to the inlet is installed at the feed end of the elevator 6, and a second auger 10 for receiving waste at the outlet is installed at the discharge end of the elevator 6. Specifically, the first auger 16 and the second auger 10 here can also be called screw conveyors.

[0034] Specifically, the conveying directions of the first auger 16 and the second auger 10 are both horizontal. More specifically, the axes of the first auger 16 and the second auger 10 are parallel to the second direction.

[0035] It can be seen that, along the second direction, the first auger 16 rotates to transport the waste at both ends of the silo 1 to the lower end inlet of the elevator 6 in the middle of the silo 1. When the elevator 6 does not move along the second direction, the first auger 16 can avoid insufficient mud at the inlet of the elevator 6 due to excessive viscosity of the mud and insufficient flow speed.

[0036] Specifically, the outer shell 63 of the elevator 6 includes a top cover 9 at the uppermost end, and the top cover 9 spans the waste outlet at the upper end of the elevator 6 and the inlet of the second auger 10 .

[0037] In this embodiment, the conveying line of the elevator 6 realizes the conveying of waste along the third direction. In order to realize the driving of the conveying line, driving wheels 17 are respectively provided at the inlet and outlet of the elevator 6, and the conveying belt or conveying chain is sleeved on the outside of the driving wheel 17. Among them, the driving wheel 17 at the inlet of the elevator 6 is connected to the rotating shaft 161 of the first auger 16 through the wheel axle 171. At this time, the rotation of the driving wheel 17 on the elevator 6 can drive the first auger 16 to rotate synchronously. This setting does not require the additional setting of corresponding driving equipment, and makes the working rhythm of the first auger 16 and the elevator 6 determined, and the first auger 16 can be used to stably provide waste mud to the elevator 6.

[0038] In this embodiment, the wheel axle 171 and the rotating shaft 161 are rotatably connected by a pin 172, and the pin 172 is perpendicular to the axis of the wheel axle 171. A torsion spring (not shown in the figure) is installed on the pin 172, which can drive the rotating shaft 161 to rotate from a state perpendicular to the wheel axle 171 to a state coaxial with the wheel axle 171. When the wheel axle 171 and the rotating shaft 161 are perpendicular, they are locked by a locking pin (not shown in the figure) that runs through the two. In the first working state, the wheel axle 171 and the rotating shaft 161 are coaxially arranged, so that the first auger 16 can be used to supply mud waste to the elevator 6. See Fig. 9 In the second state, it is convenient to rotate the rotating shaft 161 of the first auger 16 to the vertical wheel shaft 171. At this time, the axial direction of the rotating shaft 161 in the first auger 16 is parallel to the third direction, and the first auger 16 is stored on both sides of the elevator 6, so that the first auger 16 can be rotated into the inner cavity of the slide seat 3 together with the feeding end of the elevator 6.

[0039] Specifically, one of the wheel axle 171 and the rotating shaft 161 has a protrusion, and the other has a groove, the protrusion is inserted into the groove, and the wheel axle 171 and the rotating shaft 161 are respectively provided with pin holes, and the pin holes of the two are aligned and then the above-mentioned pin 172 can be inserted.

[0040] In this embodiment, a rack 2 is provided on the upper surface of the guide rail 15 along the first direction, and a gear 13 meshing with the rack 2 is provided on the slide 3, and the gear 13 is driven by a power assembly. Specifically, the length of the rack 2 here is equal to the length of the guide rail 15, the lower surface of the rack 2 is attached to and fixed to the upper surface of the guide rail 15, and the upper surface of the rack 2 has a plurality of teeth arranged in sequence along the first direction. The gear 13 is overlapped on the upper surface of the rack 2 and the two mesh with each other. Preferably, the number of the gears 13 here is four, and the four gears 13 are respectively arranged at the corners of the slide 3 along the second direction and the first direction. A motor for driving the gear 13 to rotate is installed at at least one of the gears 13, and the motor is fixed by the slide 3. That is, the motor serves as the above-mentioned power assembly.

[0041] In this embodiment, a locking wheel 12 is mounted on the slide 3, and the locking wheel 12 is in contact with the lower surface of the guide rail 15. Specifically, the locking wheel 12 is rotatably connected to the slide 3 via a rotating shaft and a corresponding supporting structure, and the rotation axis of the locking wheel 12 is parallel to the second direction.

[0042] This embodiment does not require additional removal of the guide assembly and the lifting drive assembly, so that the lifting machine 6 can be quickly turned from a vertical state to a horizontal state.

[0043] Specifically, the guide assembly includes a slide rail 11, a slider 19, and two rotating seats 21, the rotation axes of which coincide with each other, and the rotation axes of the rotating seats 21 are parallel to the second direction. The two rotating seats 21 are respectively rotatably mounted on the side walls of the slide 3 perpendicular to the second direction, the rotating seat 21 is fixed to the slider 19, the slide rail 11 is fixed to the side wall of the elevator 6 perpendicular to the second direction, and the slider 19 is slidably connected to the slide rail 11; the rotating seat 21 can be rotated and fixed to adjust the orientation of the slider 19 and the slide rail 11. This arrangement enables the guide assembly to rotate with the rotating seat 21, and realizes its guidance or support for the elevator 6 in the first working state and the second working state, respectively, to prevent the guide assembly from affecting the elevator 6 from rotating from vertical to horizontal.

[0044] Specifically, the number of guide assemblies here is two, and the two guide assemblies are respectively arranged on both sides of the elevator 6 along the second direction. The number of slide rails 11 in each guide assembly can be single, and each slide rail 11 is arranged at the center of the elevator 6 along the first direction, and the slider 19 is arranged at the center of the slide seat 3 along the first direction.

[0045] In some other embodiments, the guide assembly can replace the slide rail 11 with a guide rod (not shown in the figure), and replace the slider with a guide block (not shown in the figure). The guide block is provided with a guide hole, and the guide rod passes through the guide hole to achieve a sliding connection between the two.

[0046] In this embodiment, the lifting drive assembly includes a lead screw 14 and a nut seat. The nut seat is detachably fixed to the side wall of the elevator 6 perpendicular to the second direction. The lead screw 14 is rotatably installed on the side wall of the slide 3; the axial direction of the lead screw 14 is parallel to the third direction. In the first working state, the lead screw 14 and the nut seat are matched by threads. In the second working state, the lead screw 14 rotates to disengage from the nut seat so that the lifting drive assembly does not hinder the rotation of the elevator 6 around the axis of the rotating seat 21. Specifically, the lifting motor 5 is fixed to the side wall of the slide 3 through the bracket 4, and the output shaft of the lifting motor 5 is coaxially connected to the lead screw 14. This makes it possible for the lifting drive assembly to not affect the rotation of the elevator 6 around the axis of the rotating seat 21, so that the elevator 6 and even the conveying and loading device can be quickly switched between the first working state and the second working state.

[0047] In some other embodiments, the lead screw is rotatably mounted on the side wall of the rotating seat 21, and the lead screw and the nut seat can rotate synchronously with the rotating seat. Specifically, the lifting motor is fixed to the side wall of the rotating seat 21 through a bracket, and the output shaft of the lifting motor is coaxially connected to the lead screw. Furthermore, when the nut seat and the lead screw are not separated, the nut seat and the lead screw can also rotate synchronously with the rotating seat 21 without hindering the movement of the lifting machine.

[0048] In this embodiment, a limit block (not shown in the figure) is detachably installed at the end of the lead screw 14. Specifically, the limit block in this embodiment can be detachably fixed to the lead screw 14 by a threaded connection. In some other embodiments, the limit block can be detachably fixed to the lead screw 14 by other structural parts such as buckles or clamps, which can be set by those skilled in the art. In the case of installing a limit block on the lead screw 14, it can prevent the lead screw 14 from rotating beyond a preset range when the hoist 6 is lifted vertically, and prevent the lead screw 14 from accidentally disengaging from the nut seat. In the case of removing the limit block, it can prevent the limit block used for limiting from affecting the active disengagement of the lead screw 14 and the nut seat.

[0049] In this embodiment, the locking assembly includes a positioning pin 20, and pin holes are respectively provided on the rotating seat 21 and the sliding seat 3. In the first state, the pin holes of the rotating seat 21 and the sliding seat 3 are aligned and the positioning pin 20 is inserted; in the second state, the positioning pin 20 is removed from the pin hole. Specifically, a boss 22 is fixedly provided on the outer wall of the sliding seat 3, and the boss 22 has a first pin hole, and a second pin hole is provided on the outer peripheral side wall of the rotating seat 21. After the first pin hole and the second pin hole are aligned, the above-mentioned positioning pin 20 can be inserted. At this time, the axis of the second pin hole on the rotating seat 21 is vertical and passes through the rotation axis of the rotating seat 21.

[0050] In some other embodiments, the rotating seat 21 is embedded in the inner wall of the sliding seat 3, and the pin holes on the rotating seat 21 and the sliding seat 3 are extended along the second direction. The pin holes of the two can penetrate through themselves.

[0051] In this embodiment, a roller 18 is disposed at the lower end of the fixing frame 62, and the fixing frame 62 contacts the bottom wall of the silo 1 through the roller 18, thereby avoiding scratching of the two. At the same time, the roller 18 can reduce the friction between the elevator 6 and the silo 1 when switching between the first working state and the second working state.

[0052] In this embodiment, a rotating power assembly (not shown in the figure) is installed on the side wall of the slide seat 3, and the rotating power assembly can drive the rotating seat 21 to rotate. Specifically, the rotating power assembly here can use a reduction motor, and the reduction motor here is a power-off self-locking motor. The rotating power assembly here can also be other structures such as a hydraulic motor. The rotating power assembly here has a driving shaft, and the driving shaft can drive the rotating seat to rotate through a gear transmission assembly or a pulley transmission assembly, or the driving shaft can be directly fixed coaxially with the rotating seat 21.

[0053] Specifically, a rotating power assembly is provided only at one of the rotating seats 21. At this time, one rotating seat 21 is actively rotating, and the other rotating seat 21 is driven to rotate along with the hoist 6. In other embodiments, when the two rotating power assemblies can be driven synchronously, a rotating power assembly can be connected to each rotating seat 21.

[0054] Working principle: In the first working state, the elevator 6 is arranged vertically, and the corresponding pin hole on the rotating seat 21 is aligned with the corresponding pin hole on the boss 22, and the positioning pin 20 is inserted. At this time, the elevator 6 plays the function of lifting the mud waste to the transfer vehicle. Before the mud waste is stored in the silo 1, the elevator 6 is lifted to the extreme position relative to the silo 1 by the lifting drive assembly and the guide assembly, so that the lower end of the elevator 6 has a large distance from the bottom wall of the silo 1, and the elevator 6 will not affect the processing and storage of the mud waste in the silo 1. When the mud waste in the silo 1 needs to be lifted by the elevator 6 for loading and transportation, the lifting drive assembly drives the elevator 6 to move downward, and the lower end of the elevator 6 is inserted into the mud waste in the silo 1, so that the scraper 61 of the elevator 6 contacts the mud waste to facilitate scraping the waste.

[0055] The gear 13 on the slide 3 cooperates with the rack 2, so that the elevator 6 moves along the first direction driven by the gear 13, and the first auger 16 rotates to transport the waste at both ends of the silo 1 along the second direction to a position close to the lower end inlet of the elevator 6. The elevator 6 is started, and the scraper 61 continuously scrapes the waste in the silo 1 and lifts it to the discharge port. The waste output from the discharge port of the bucket elevator 6 is received by the feed port of the second auger 10, and then the second auger 10 transports the corresponding waste mud horizontally along the second direction to the transfer vehicle.

[0056] In the second working state, remove the locating pins 20 on the rotating seat 21 and the slide 3, so that the locking assembly is disengaged from the locking of the rotating seat 21. Then use the lifting drive assembly to drive the entire elevator 6 to lift a certain distance, so that the feed end of the elevator 6 can be inserted into the inner cavity of the slide 3 after rotation. The first auger 16 is rotated to be retracted to both sides of the elevator 6, and the rotating shaft 161 and the wheel shaft 171 of the first auger 16 are locked by the locking pin so as to rotate synchronously with the elevator 6. Then remove the connecting member 32 on one side of the slide 3 along the first direction, and reserve corresponding space for the elevator 6 to rotate to the horizontal before the elevator 6 is rotated to prevent the connecting member 32 from hindering the rotation of the elevator 6.

[0057] The rotating power assembly on the slide 3 is used to cooperate with the external crane and slings to drive the hoist 6 from a vertical state to a horizontal state. The feed end of the hoist 6 and the first auger 16 are both received in the inner cavity of the slide 3. At this time, the hoist 6 is arranged horizontally and supported by the guide rail 15.

[0058] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0059] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
