Description

Technical Field

[0001] The invention relates to the technical field of soft beach engineering vehicles, and more particularly to an engineering vehicle applied to the soft beach of a tailings pond. Background Art

[0002] The tailings discharged from mines contain a large amount of water, which makes the surface of the tailings pond a soft beach (mud and water mixture), which is very unfavorable for engineering vehicles to enter. In the tailings field, engineering vehicles are often required to be equipped with construction, maintenance, monitoring and other equipment, and need to enter the soft beach to carry out drainage pipe laying, drilling sampling, tailings turning and drying, installation of concrete arch plates, inspections and other construction operations.

[0003] However, since the wheels of engineering vehicles in the prior art are generally composed of a rim and spokes to form a wheel frame, and then a rubber tire is connected to the wheel frame, but this type of wheel is only suitable for traveling on the road, but not for traveling in a mud-water mixture, therefore, if an engineering vehicle equipped with this wheel travels on a soft beach, it is easy for the engineering vehicle to sink into it.

[0004] Moreover, current technology does not allow engineering vehicles to enter the soft beach. In actual operation, pontoons are assembled into a floating bridge, and personnel use small bucket trucks to transfer equipment to the pontoon operation area. However, this not only consumes a lot of labor, but also leads to low transportation efficiency. If larger equipment needs to be transported, the larger equipment needs to be disassembled into multiple parts for transportation, and then these parts are assembled after being transported to the work site, which consumes more labor and leads to lower transportation efficiency. At the same time, when people walk on the floating bridge composed of multiple pontoons, the floating bridge is prone to shaking, which will bring greater personal danger.

[0005] Therefore, how to provide an engineering vehicle for use on soft beaches of tailings ponds that is easy to travel on and not prone to shaking during operation is an urgent problem that technicians in this field need to solve. Summary of the invention

[0006] In view of this, the present invention provides an engineering vehicle applied to the soft beach surface of a tailings pond, aiming to solve at least some of the above-mentioned technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0010] There are multiple spiral drums, which are distributed on both sides of the frame chassis along the y-axis direction. The length of each spiral drum extends along the x-axis direction. At the same time, each spiral drum is rotatably connected to the frame chassis, and each is connected to a first hydraulic motor through a first transmission mechanism. Each first hydraulic motor is connected to the frame chassis;

[0011] The control cabin is connected to the frame chassis, and the control cabin is equipped with a control system. At the same time, the control system hydraulically controls the lifting mechanism and each first hydraulic motor respectively through a hydraulic station.

[0012] Preferably, the hopper includes: a storage bin, two ear plates, and multiple support legs;

[0013] The top end of the storage bin is an open end, and the installation opening penetrates through the middle of the frame chassis. The storage bin is embedded in the installation opening and can reciprocate vertically in the installation opening;

[0014] One side of the two ear plates is correspondingly connected to two opposite side walls of the storage bin in the x-axis direction, and both are horizontally arranged. One side of each ear plate away from the storage bin extends along the x-axis to the outside of the frame chassis, and multiple vertically arranged support legs are connected at intervals along the y-axis. Each support leg is connected to the frame chassis through one lifting mechanism;

[0015] The control cabin is connected to one of the ear plates.

[0016] Preferably, the lifting mechanism includes:

[0017] A second hydraulic motor, which is fixed on the support leg;

[0018] A rack. Each support leg is a channel steel. At the same time, at the position of the frame chassis corresponding to each support leg, a strip-shaped "U" groove with a length extending in the vertical direction is opened. The side opening of each strip-shaped "U" groove is butt-connected and communicated with the side opening of the corresponding channel steel; the rack is fixed in the corresponding strip-shaped "U" groove, and the extending direction of the length of the rack is the same as the length extending direction of the corresponding strip-shaped "U" groove. At the same time, the toothed surface of each rack is close to the side opening of the corresponding strip-shaped "U" groove;

[0019] Gears, each of which is concentrically connected with a central shaft, and each of the gears is rotatably connected in the groove of the corresponding channel steel through the corresponding central shaft. At the same time, each of the gears is in meshing transmission connection with the corresponding rack; each of the central shafts is connected to the output shaft of the corresponding second hydraulic motor through a second transmission mechanism. At the same time, each of the second hydraulic motors is hydraulically connected to the control system through the hydraulic station to drive the corresponding gear to rotate through the corresponding central shaft, and each of the gears drives the corresponding rack to reciprocate vertically.

[0020] Preferably, the bottom end of the support leg is flush with the bottom end of the storage bin.

[0021] Preferably, a plurality of positioning grooves are formed at the bottom end of the storage bin.

[0022] Preferably, the bottom end of the support leg is a tip.

[0023] Preferably, a through hole penetrates through the bottom end of the storage bin, and a water-proof inlet pipe concentric with the through hole is vertically connected to the bottom of the storage bin. The inner diameter of the water-proof inlet pipe is equal to the aperture of the through hole. At the same time, the top port of the water-proof inlet pipe is covered with a lid.

[0024] Preferably, the through hole and the water-proof inlet pipe are both located at one end of the storage bin far from the control room. At the same time, a hydraulic crane is connected to the other ear plate far from the control room, and the hydraulic crane is hydraulically connected to the control system through the hydraulic station.

[0025] Preferably, it further includes: a bearing plate, and the bearing plate is detachably connected to the hydraulic crane through a suspension rope.

[0026] Preferably, anti-collision tires are connected to the periphery of the frame-type chassis.

[0027] Through the above technical solutions, compared with the prior art, the present invention discloses an engineering vehicle applied to the soft beach surface of a tailings pond, and the following technical effects can be achieved:

[0028] The engineering vehicle for the soft beach surface of the tailings pond in this application travels on the soft beach surface through multiple spiral drums, so it is not easy to sink in the soft beach surface, but is suitable for traveling in the soft beach surface.

[0029] When the present application travels on a soft beach through multiple spiral drums, the operator controls the hydraulic station through the control system to drive the lifting mechanism to the rising state. As a result, the lifting mechanism drives the bucket to the rising state. At this time, the bottom end of the bucket can be far away from the soft beach and not in contact with the soft beach. Therefore, during the process of the present application traveling on the soft beach, there will be no problem of traveling resistance generated due to the contact between the bucket and the soft beach, which is beneficial to the present application traveling on the soft beach.

[0030] When the present application travels to the position to be constructed / maintained on the soft beach, the operator operates the control system, and then controls the hydraulic station to simultaneously close multiple first hydraulic motors through the hydraulic station, so that the multiple spiral drums stop working, thereby controlling the present application to stop at the position to be constructed / maintained. At the same time, the operator controls the hydraulic station through the control system to drive the lifting mechanism to descend, so as to drive the bucket to descend. Until the bottom end of the bucket supports on the bottom of the soft beach, the operator controls the hydraulic station through the control system to drive the lifting mechanism to stop descending. At this time, the bucket stops in the state of supporting on the bottom of the soft beach. Thus, when the worker works in the bucket at this time, due to the frictional resistance between the bottom end of the bucket and the bottom end of the soft beach, it is not easy to make the engineering vehicle of the present application shake on the soft beach, which is not only beneficial to the quality of the staff's work, but also improves the safety of the staff.

Detailed implementation manner

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0038] The embodiment of the present invention discloses an engineering vehicle applied to a soft beach surface of a tailings pond, including: a frame chassis 1, a spiral drum 2, a carriage 3 and a control cab 4, wherein:

[0039] The frame chassis 1 has a vertically penetrating mounting opening 10. At the same time, the carriage 3 is connected to the frame chassis 1 through a lifting mechanism 5, and the carriage 3 can be lifted within the mounting opening 10;

[0040] There are multiple spiral drums 2, which are distributed on both sides of the frame chassis 1 along the y-axis direction, and the length of each spiral drum 2 extends along the x-axis direction. At the same time, each spiral drum 2 is rotatably connected to the frame chassis 1, and each is connected to a first hydraulic motor 6 through a first transmission mechanism, and each first hydraulic motor 6 is connected to the frame chassis 1;

[0041] The control cab 4 is connected to the frame chassis 1, and a control system is provided in the control cab 4. At the same time, the control system hydraulically controls the lifting mechanism 5 and each first hydraulic motor 6 respectively through a hydraulic station.

[0042] The control system installed in the control cab 4 of the present application is common general knowledge in this field, and the structure of the control system is prior art and not the point protected by the present application, so it will not be elaborated here.

[0043] Among them, both ends of each spiral drum 2 are concentrically connected with a rotating shaft 21. The two rotating shafts 21 of each spiral drum 2 are rotatably connected to the frame chassis 1, and one of the rotating shafts 21 of each spiral drum 2 is connected to the output shaft of the corresponding first hydraulic motor 6 through the corresponding first transmission mechanism.

[0044] When this application is in use: The operator controls the hydraulic station through the control system to drive multiple first hydraulic motors 6 to start simultaneously. Then, each first hydraulic motor 6 of this application drives the corresponding spiral drum 2 to rotate through the corresponding first transmission mechanism, so that the tailings pond soft beach surface engineering vehicle of this application can travel on the soft beach through multiple spiral drums 2, and it is not easy to sink into the soft beach surface, but is suitable for traveling in the soft beach surface;

[0045] Moreover, when this application travels on the soft beach through multiple spiral drums 2, the operator controls the hydraulic station through the control system to drive the lifting mechanism 5 to be in the rising state. Thus, the lifting mechanism 5 drives the hopper 3 to be in the rising state. At this time, the bottom end of the hopper 3 can be far away from the soft beach surface and not in contact with the soft beach surface. Therefore, during the process of this application traveling in the soft beach surface, there will be no problem of traveling resistance generated due to the contact between the hopper 3 and the soft beach surface, which is conducive to the travel of this application in the soft beach surface.

[0046] When this application travels to the position where construction / repair is required on the soft beach surface, the operator operates the control system, and then controls the hydraulic station to simultaneously turn off multiple first hydraulic motors 6 through the hydraulic station, so that multiple spiral drums 2 stop working, thereby controlling this application to stop at the position where construction / repair is required. At the same time, the operator controls the hydraulic station through the control system to drive the lifting mechanism 5 to descend, so as to drive the hopper 3 to descend until the bottom end of the hopper 3 supports on the bottom of the soft beach surface. Then, the operator controls the hydraulic station through the control system to drive the lifting mechanism 5 not to continue descending. At this time, the hopper 3 stops in the state of supporting on the bottom of the soft beach surface. Thus, when a worker operates in the hopper 3 (when the worker stands in the hopper 3, the equipment in the hopper 3 can be unloaded onto the soft beach surface, and then the person stands in the hopper 3 to operate the equipment on the soft beach surface), due to the frictional resistance between the bottom end of the hopper 3 and the bottom end of the soft beach surface, it is not easy to make the engineering vehicle of this application shake on the soft beach surface. Therefore, it is not only conducive to the quality of the staff's operation, but also improves the safety of the staff.

[0047] To further optimize the above technical solution, the hopper 3 includes: a storage bin 31, two ear plates 32, and multiple support legs 33;

[0048] The top end of the storage bin 31 is an open end, and the installation opening 10 penetrates through the middle of the frame-type chassis 1. The storage bin 31 is embedded in the installation opening 10 and can reciprocate vertically in the installation opening 10;

[0049] One side of the two ear plates 32 is correspondingly connected to the two side walls of the storage bin 31 opposite to each other in the x-axis direction, and both are horizontally arranged. Moreover, one side of each ear plate 32 away from the storage bin 31 extends along the x-axis to the outside of the frame-type chassis 1, and multiple vertically arranged support legs 33 are connected at intervals along the y-axis direction. Each support leg 33 is connected to the frame-type chassis 1 through a lifting mechanism 5;

[0050] The control room 4 is connected to one of the ear plates 32 .

[0051] The present application adopts the above technical solution. Since the truck bed 3 is located on the frame chassis 1 through the mounting opening 10, when equipment is loaded on the truck bed 3, the center of gravity is not easily shifted, which is beneficial to the stability of the present application.

[0052] Furthermore, the two ear plates 32 are separated on opposite sides of the storage bin 31 in the x-axis direction, and each of the two ear plates 32 is connected with a plurality of vertically arranged support legs 33 at intervals along the y-axis direction, so that each support leg 33 is connected to the frame chassis 1 through a lifting mechanism 5, so that the storage bin 31 is more stable during the lifting process, thereby benefiting the safety of the equipment and the staff.

[0053] In addition, one side of each ear plate 32 connected to the corresponding plurality of supporting legs 33 extends to the periphery of the frame chassis 1 , thereby preventing the supporting legs 33 from affecting the normal operation of the spiral drum 2 .

[0054] In order to further optimize the above technical solution, the lifting mechanism 5 includes:

[0055] A second hydraulic motor 51, the second hydraulic motor 51 is fixed on the support leg 33;

[0056] The rack 52, each supporting leg 33 is a channel steel, and at the same time, a strip-shaped "U"-shaped groove 330 extending in the vertical direction is opened at the position corresponding to each supporting leg 33 of the frame-type chassis 1, and the side opening of each strip-shaped "U"-shaped groove 330 is connected to the side opening of the corresponding channel steel; the rack 52 is fixed in the corresponding strip-shaped "U"-shaped groove 330, and the extension direction of the length of the rack 52 is the same as the extension direction of the length of the corresponding strip-shaped "U"-shaped groove 330, and the toothed surface of each rack 52 is close to the side opening of the corresponding strip-shaped "U"-shaped groove 330;

[0057] Gears 53, each gear 53 is concentrically connected with a center shaft, and each gear 53 is rotatably connected in the groove of the corresponding channel steel through the corresponding center shaft, and each gear 53 is meshingly connected with the corresponding rack 52 for transmission; each center shaft is connected to the output shaft of the corresponding second hydraulic motor 51 through a second transmission mechanism, and each second hydraulic motor 51 is hydraulically connected to the control system through a hydraulic station to drive the corresponding gear 53 to rotate through the corresponding center shaft, and each gear 53 drives the corresponding rack 52 to reciprocate in the vertical direction.

[0058] In the present application, when the dump body 3 needs to be raised, the control system controls the hydraulic station to drive each second hydraulic motor 51 to rotate forward. Then each second hydraulic motor 51 drives the corresponding gear 53 to rotate forward through the corresponding central shaft, and engages with the corresponding rack 52 for transmission. Since each rack 52 is fixed in the corresponding strip-shaped "U" groove 330 formed on the frame chassis 1, and each second hydraulic motor 51 and the corresponding gear 53 are both connected to the corresponding support leg 33, at this time each gear 53 drives the corresponding support leg 33 to rise along the length direction of the corresponding rack 52. If the dump body 3 needs to be lowered, the second hydraulic motor 51 is driven to rotate reversely.

[0059] To further optimize the above technical solution, the bottom end of the support leg 33 is flush with the bottom end of the storage bin 31.

[0060] In the present application, when the storage bin 31 rises to not contact the soft beach surface, the support leg 33 will not contact the soft beach surface either. Therefore, during the process of the present application moving on the soft beach surface, there will be no traveling resistance between the support leg 33 and the soft beach surface. Moreover, when the present application stops on the soft beach surface, and when the bottom end of the storage bin 31 supports on the bottom end of the soft beach surface, the bottom end of the support leg 33 will also support on the bottom end of the soft beach surface at the same time. Thus, the present application is supported on the bottom end of the soft beach surface by the bottom end of the storage bin 31 and the multiple support legs 33 around it. Then when the staff operates inside the storage bin 31, it is less likely to cause the present application to shake.

[0061] To further optimize the above technical solution, a plurality of positioning grooves 310 are formed at the bottom end of the storage bin 31.

[0062] In the present application, when the storage bin 31 descends until its bottom end supports on the bottom end of the soft beach surface, the groove walls between every two adjacent positioning grooves 310 at the bottom end of the storage bin 31 can be easily inserted into the soft beach surface, thereby improving the grasping (at the bottom end of the soft beach surface) ability of the bottom end of the storage bin 31. Then when the staff operates inside the storage bin 31, it is less likely to cause the present application to shake.

[0063] To further optimize the above technical solution, the bottom end of the support leg 33 is a tip.

[0064] In the present application, when the storage bin 31 descends until its bottom end supports on the bottom end of the soft beach surface, the bottom tip of the support leg 33 can be easily inserted into the bottom end of the soft beach surface and make the connection between the support leg 33 and the soft beach surface more stable.

[0065] To further optimize the above technical solution, a through hole 300 is formed through the bottom end of the storage bin 31, and a water - proof inlet pipe 301 concentric with the through hole 300 is vertically connected to the bottom of the storage bin 31. The inner diameter of the water - proof inlet pipe 301 is equal to the aperture of the through hole 300, and a lid 302 is provided to cover the top port of the water - proof inlet pipe 301.

[0066] Among them, the lid 302 can be snap - connected to the top port of the water - proof inlet pipe 301, or a part of the edge of the lid 302 can be hinged to the side wall of the water - proof inlet pipe 301, and the other part of the edge of the lid 302 is in open - close contact with the side wall of the water - proof inlet pipe 301 and is locked.

[0067] In this application, when the top port of the water - proof inlet pipe 301 is covered by the lid 302, arch plates for engineering installation, sandbags for flood fighting and rescue, etc. can be placed in the storage bin 31. When the lid 302 no longer covers the top port of the water - proof inlet pipe 301, a drilling rig can be installed in the storage bin 31, so that this application can transport a variety of equipment and has multiple functions.

[0068] Moreover, when the lid 302 no longer covers the top port of the water - proof inlet pipe 301 and a drilling rig is installed in the storage bin 31, the drill rod of the drilling rig can pass through the water - proof inlet pipe 301, which is convenient for engineering exploration drilling and sampling, and anti - seepage drilling by the drilling rig, without the need for multiple workers to lift the drilling rig out together, thus reducing the labor intensity of workers.

[0069] At the same time, in this application, by vertically connecting the water - proof inlet pipe 301 concentric with the through hole 300 to the bottom of the storage bin 31, it is not easy for the muddy water mixture at the bottom end of the storage bin 31 to enter the storage bin 31 through the through hole 300.

[0070] To further optimize the above technical solution, both the through hole 300 and the water - proof inlet pipe 301 are located at one end of the storage bin 31 far from the control room 4. At the same time, a hydraulic deck crane 7 is connected to another ear plate 32 far from the control room 4, and the hydraulic deck crane 7 is hydraulically connected to the control system through a hydraulic station.

[0071] Among them, the structure of the hydraulic deck crane 7 is a mature existing technology and will not be elaborated here.

[0072] In this application, by using the hydraulic deck crane 7, the equipment in the storage bin 31 can be lifted, thus reducing the labor of workers.

[0073] To further optimize the above technical solution, it further includes: a bearing plate 8, and the bearing plate 8 is detachably connected to the hydraulic deck crane 7 through a lifting rope 9.

[0074] With the above technical solution of the present application, when the hydraulic deck crane 7 hoists easily damaged equipment such as sandbags in the storage bin 31, if necessary, the bearing plate 8 can be connected to the hook of the hydraulic deck crane 7 through the lifting rope 9. Then, the worker places the easily damaged equipment such as sandbags on the bearing plate 8 for hoisting, thus preventing the hook of the hydraulic deck crane 7 from damaging the equipment such as sandbags; when the hydraulic deck crane 7 hoists equipment such as a drilling rig, the bearing plate 8 is not installed at this time, so as to hoist the drilling rig and the like through the hook of the hydraulic deck crane 7.

[0075] To further optimize the above technical solution, anti-collision tires are connected to the periphery of the frame chassis 1.

[0076] With the above technical solution of the present application, the anti-collision performance of the present application is enhanced through the anti-collision tires.

[0077] The hydraulic station of the present application can be connected to the truck bed 3, and the control system controls the first hydraulic motor 6, the second hydraulic motor 51 and the hydraulic deck crane 7 respectively through the hydraulic station. This is the prior art and will not be elaborated here.

[0078] Moreover, the structure of the hydraulic station is also the prior art and will not be elaborated here. At the same time, the control system controls the hydraulic station through the solenoid valve, which is also the prior art and will not be elaborated here.
