DETAILED DESCRIPTION

[0036] In order to make the purpose of the invention, technical solutions and beneficial effects of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] like Figures 1 to 4 As shown, a closed water retaining equipment carrying mechanism includes:

[0038] The traveling mechanism includes a carrying trolley 1, which drives the water retaining equipment to move horizontally;

[0039] A lifting mechanism, which is provided on the carrying trolley 1 to drive the water retaining equipment to move longitudinally;

[0040] A control unit is connected to the traveling mechanism and the lifting mechanism respectively to control the start and stop and the running path of the traveling mechanism and / or the lifting mechanism;

[0041] During operation, the control unit controls the lifting mechanism to adjust the horizontal height of the water retaining equipment, and the control unit controls the walking mechanism to move the water retaining equipment from the water retaining equipment stacking area to the designated position to block the air shaft mouth.

[0042] The control unit includes a control box 6, an operating control box 7, and a programmable logic controller (PLC). The PLC is located in the control box 6 and contains a pre-set control program that controls the start, stop, and travel path of the lifting and traveling mechanisms. The operator can control the control unit by operating the operating control box 7.

[0043] In some embodiments of the present invention, the transport trolley 1 includes a frame 4 on both sides and a crossbeam 22 connected to the upper parts of the two frames 4; the lifting mechanism includes two lifting units, each lifting unit is respectively arranged on one frame 4, and a accommodating space is formed in each frame 4.

[0044] Because the two frames 4 are connected by a crossbeam 22, synchronous operation of both sides of the transport vehicle 1 is achieved, ensuring stability when transporting the water-blocking equipment. Furthermore, since each frame 4 has a storage space, the lifting unit is placed in the storage space, which reduces the space occupied by the present invention. Moreover, the key components of the lifting mechanism and the running mechanism are integrated on the frame 4, with a reasonable layout, facilitating the coordinated operation of the various components, and ensuring stability and load-bearing capacity in the overall structure.

[0045] Furthermore, the enclosed water retaining equipment carrying mechanism includes a power source, which is arranged on the crossbeam 22 and is connected to the walking mechanism and the lifting mechanism respectively. Preferably, the power source is a micro hydraulic station 5.

[0046] In detail, in the present invention, the lifting mechanism is used to adjust the horizontal height of the water retaining equipment, that is, the water retaining equipment is driven to rise or fall by the lifting mechanism, wherein the two hydraulic cylinders 18 are powered by a power source.

[0047] In some embodiments of the present invention, each lifting unit is correspondingly arranged in a receiving space; each receiving space is provided with a longitudinally arranged pulley track 21;

[0048] Each lifting unit includes a lifting pulley 20, a lifting bracket 2, a lifting chain 19, a hydraulic cylinder 18, a lifting pulley 23, a chain connecting seat 24 and a chain fixing seat 25; wherein, the lifting bracket 2 is used to support the water retaining equipment, and the water retaining equipment is supported by the lifting bracket 2. When the lifting bracket 2 is lifted or lowered with the lifting pulley 20, the water retaining equipment is driven to lift or lower.

[0049] The chain connecting seat 24 and the lifting bracket 2 are respectively arranged on the lifting pulley 20; the hydraulic cylinder 18 includes a cylinder body and a piston rod that is telescopic in the cylinder body, and the piston rod is telescopic relative to the cylinder body in the vertical direction. The end of the piston rod is provided with a lifting pulley 23, and the lifting pulley 23 includes a lifting pulley groove;

[0050] The chain fixing seat 25 is provided at the lower part of the cylinder body, one end of the lifting chain 19 is fixed on the chain fixing seat 25, and the other end is provided on the chain connecting seat 24, and the middle section of the lifting chain 19 is provided around the pulley groove;

[0051] When the piston rod extends upward, it pushes the lifting pulley 23 to extend upward, and the lifting chain 19 drives the chain connecting seat 24, the lifting pulley 20 and the lifting bracket 2 to rise.

[0052] The lifting trolleys 20 on either side of the transport trolley 1 are driven synchronously by a single power unit. The micro-hydraulic station 5, serving as the power source, offers high efficiency and stability. Its compact design allows for convenient placement on the crossbeam 22 of the transport trolley 1, facilitating maintenance without disrupting the overall layout of the trolley 1. Key components such as the cylinder, chain, and pulley are housed within the housing, creating a simple and efficient transmission system.

[0053] The hydraulic oil flow and pressure of the lifting pulleys 20 on both sides are precisely controlled by the hydraulic synchronous diverter valve, which realizes fast and smooth synchronous lifting movement and ensures the horizontality and stability of the water retaining equipment during the lifting process.

[0054] When the piston rod extends upward relative to the cylinder body, it pushes the lifting pulley 23 upward. At this point, because the lifting chain 19 is positioned in the pulley groove of the lifting pulley 23, the lifting pulley 23 pushes the lifting chain 19, which in turn drives the chain connector 24 and the lifting bracket 2 upward, and pushes the lifting trolley 20 upward within the trolley track 21, thereby raising the water retaining equipment. When the piston rod of the hydraulic cylinder 18 extends and retracts, it moves the lifting chain 19. Because the lifting chain 19 is connected to the lifting trolley 20, the movement of the lifting chain 19 enables the lifting trolley 20 to achieve its lifting function.

[0055] Wherein, in the present invention, by the setting of lifting chain 19 and lifting pulley 20, realize linkage with pulley. The middle part of chain is placed in the pulley groove of oil cylinder top.

[0056] The lifting pulley 23 is configured to act like a movable pulley. Leveraging the unique mechanical transmission principle of the lifting pulley 23, the lifting chain 19 can move at twice the speed of the hydraulic cylinder 18. This speed-increasing mechanism effectively increases the lifting speed of the lifting trolley 20, significantly improving the efficiency of the entire lifting system.

[0057] In some embodiments of the present invention, wheels 8 are provided at the bottom of the transport trolley 1 , and each wheel 8 is equipped with a guide roller 3 , which is connected to the control unit.

[0058] As a specific embodiment of the present invention, four wheels 8 are provided at the bottom of the transport trolley 1, that is, the transport trolley 1 adopts a four-wheel structure, which enables the transport trolley 1 to move smoothly horizontally.

[0059] Furthermore, each wheel 8 is equipped with a guide roller 3, and each guide roller 3 is connected to a control unit. The control unit controls the guide roller 3 so that the guide roller 3 runs along a predetermined track.

[0060] In some embodiments of the present invention, each frame 4 is provided with a carrier unit, each carrier unit is connected to a power source, and each carrier unit includes a servo motor 9, a transmission shaft 11 of the servo motor 9 is connected to the driving gear of the transition gear set 16 through a coupling 12, and the driven gear of the transition gear set 16 drives the driving gear to rotate;

[0061] The transport trolley 1 moves on the guide rail 35 , on which a guide rack 36 is provided, which meshes with the drive gear 17 ;

[0062] The carrying unit also includes a gear mounting seat 14, on which a transition gear set 16 and a driving gear 17 are both arranged. A hinge 15 is provided on the gear mounting seat 14, which allows the gear mounting seat 14 to rotate flexibly to adapt to the smooth running of the carrying trolley 1 on the guide rail 35.

[0063] In detail, in the present invention, since the transport units on the left and right sides of the transport trolley 1 are each controlled by a control unit, the control unit controls the running path of the transport trolley 1 and ensures its stability during the transport process.

[0064] Furthermore, the coupling 12 in the carrier unit is a telescopic universal coupling 12, which can effectively compensate for relative displacement caused by vibration, impact, etc., ensuring that the meshing of the gears and the guide rack 36 always maintains an appropriate buffer margin during the movement of the trolley, further improving operational reliability and durability. A reducer 10 is also connected between the coupling 12 and the servo motor 9.

[0065] Furthermore, a compression spring 13 is provided on the gear mounting seat 14 for compressing and providing pre-tightening force for the driving gear 17 to ensure close engagement between the driving gear 17 and the guide rail rack 36 .

[0066] In detail, as a specific embodiment of the present invention, the carrying trolley 1 adopts a four-wheel structure, that is, it includes four rollers, which can enable the carrying trolley 1 to move horizontally smoothly along the guide rail 35, and in order to prevent the carrying trolley 1 from derailing, a guide roller 3 is provided on each roller, and each guide roller 3 can be connected to the control unit, so that it can run safely and smoothly along the predetermined track through the control unit. On the frames 4 on both sides of the carrying trolley 1, there are respectively provided carrying units, and the carrying trolley 1 is synchronously driven by the two carrying units to ensure its stability and accuracy during movement. In addition, the walking path of the carrying trolley 1 is controlled by the PLC in the control unit, and specific path programs are corresponding to different water-blocking equipment to achieve automatic operation.

[0067] Moreover, in the present invention, the servo motor 9 in the transport mechanism drives the driving gear 17 to rotate, and the driving gear 17 is engaged with the guide rack 36 in the guide rail 35 to achieve the effect of moving the transport trolley 1 on the guide rail 35.

[0068] In addition, in the carrier unit, the mounting seat can be flexibly rotated within a certain range through the hinge 15 , which can effectively adapt to slight deformation and unevenness of the guide rail 35 .

[0069] In some embodiments of the present invention, the present invention is further provided with a human operating device 26 for carrying operation;

[0070] The manual operating device 26 includes an oil tank 30. The oil tank 30 and the oil pump 31 form an oil circuit through an oil inlet pipe 27 and an oil return pipe 28. The oil pump 31 is also externally connected to a foot pedal 29, which is connected to the oil pump 31 via a return spring 32. Preferably, the oil tank 30 is also provided with a handrail 33 to help the operator maintain balance when alternately stepping on the foot pedal 29.

[0071] Specifically, when a power outage or electrical equipment failure occurs, the human emergency operation mode can be activated immediately. The operator manually steps on the foot-operated hydraulic oil pump 31 to replace the electric drive unit, thereby achieving the lifting, opening and closing of the water retaining equipment.

[0072] Furthermore, the foot-operated hydraulic oil pump 31 adopts a double-plunger hydraulic oil pump design and is equipped with a return spring 32. When working, the person's legs stand on the two pedals of the foot pedal 29 mechanism, hold the handrails 33 with both hands, and use their own weight to alternately step on the pedals with their feet, pressing the two oil pumps 31, and the two oil pumps 31 alternately supply oil.

[0073] During operation, the two oil pumps 31 alternately supply oil, effectively ensuring the continuity and stability of the oil supply. The outlet of each plunger oil pump 31 is equipped with a hydraulic check valve to ensure that the two oil pumps 31 do not interfere with each other when working alternately, preventing the hydraulic oil from flowing back, thereby maintaining the stability of the system pressure and ensuring the smooth and reliable lifting and lowering operations of the water retaining equipment.

[0074] During use, the oil pump 31's inlet and outlet pipes are connected to the transport trolley 1's inlet and outlet pipes. By operating the hydraulic pump 31, the lifting pulley 20 is driven to lift the water retaining equipment, allowing it to be separated from the well frame. The transport trolley 1 is then pushed back to the water retaining equipment storage area, ready to be placed back in the water retaining equipment storage area. The hydraulic pump 31 is then operated again to drive the lifting pulley 20 to slowly lower the water retaining equipment onto the water retaining equipment storage area, completing the recovery of all water retaining equipment.

[0075] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
