[0040] Figures 1 to 3The present invention shows a disassembly and assembly platform 1 for the lower water chamber of the motor oil cooler in one embodiment of the utility model, which can assist in the disassembly and assembly of the lower water chamber of the oil cooler. The motor oil cooler includes an oil cooler body 3 and a lower water chamber 2, the oil cooler body 3 is suspended, and the lower water chamber 2 is detachably arranged at the lower end of the oil cooler body 3. The ends of the lower water chamber 2 and the oil cooler body 3 that are in contact are both provided with connecting flanges, and bolt holes are evenly spaced along the circumferential direction on the connecting flanges of the two. The lower water chamber 2 and the oil cooler body 3 can be detachably connected by inserting bolts in the corresponding bolt holes of the two. The bolt holes provided on the connecting flange of the lower water chamber 2 are now defined as the first bolt holes 201, and the bolt holes provided on the connecting flange of the oil cooler body 3 are defined as the second bolt holes 301.

[0041] The motor oil cooler lower water chamber disassembly and assembly platform 1 includes a base 10, a lifting mechanism 20 and a guide assembly 30. The lifting mechanism 20 is arranged on the base 10, and the guide assembly 30 is arranged on the lifting mechanism 20. The lifting mechanism 20 is used to place and lift the lower water chamber 2, so as to avoid the operator from manually lifting and lifting the lower water chamber 2 in a narrow space on site, thereby reducing manpower consumption. The guide assembly 30 plays a role in preliminary positioning and guiding, so that when the lower water chamber 2 is installed through the motor oil cooler lower water chamber disassembly and assembly platform 1, the motor oil cooler lower water chamber disassembly and assembly platform 1 with the lower water chamber 2 can be first moved to a suitable position (i.e., the position corresponding to the lower water chamber 2 and the oil cooler body 3) through the guide assembly 30, and then lifted through the lifting mechanism 20, so that when the lower water chamber 2 is lifted to a height where it contacts the oil cooler body 3, the first bolt hole 201 and the second bolt hole 301 can be connected correspondingly, and at this time, the assembly of the two can be completed by directly inserting bolts.

[0042] Specifically, the lifting mechanism 20 includes a driving component 21 and a lifting platform 22. The lifting platform 22 is arranged on the driving component 21, and is used to place the lower water chamber 2, and under the drive of the driving component 21, it is lifted back and forth relative to the base 10, thereby lifting and lowering the lower water chamber 2. The driving component 21 is arranged on the base 10, and is used to drive the lifting platform 22 to lift back and forth.

[0043] The guide assembly 30 is disposed on the lifting platform 22, and includes a guide rope 32 and a drum 31. The drum 31 is disposed on the lifting platform 22, and is used to accommodate the guide rope 32. The number of the guide rope 32 is at least one, which is wound on the drum 31, and is used to be inserted into the corresponding first bolt hole 201 and the second bolt hole 301 when the lower water chamber 2 is disassembled or installed, so as to achieve a preliminary guiding effect.

[0044] During specific use, taking the installation of the lower water chamber 2 as an example, first, the free ends of the guide rope 32 are respectively inserted into the corresponding first bolt hole 201 and the second bolt hole 301, and the motor oil cooler lower water chamber disassembly and assembly platform 1 is moved until the extension direction of the guide rope 32 between the first bolt hole 201 and the second bolt hole 301 basically coincides with the axial direction of the first bolt hole 201 and the second bolt hole 301. It can be considered that the lower water chamber 2 has been moved to the target position. In this position, the lower water chamber 2 corresponds to the oil cooler body 3. At this time, the lower water chamber 2 is lifted to achieve the docking of the corresponding first bolt hole 201 and the second bolt hole 301, and then the bolts can be inserted to complete the assembly.

[0045] The setting of the lifting mechanism 20 of the motor oil cooler lower water chamber disassembly and assembly platform 1 can firstly avoid multiple operators manually lifting and carrying the lower water chamber 2 with a certain weight in a narrow space, realize the mechanical lifting of the lower water chamber 2, reduce the consumption of manpower, avoid the potential risks during manual lifting, and improve the working efficiency. Secondly, by setting the guide component 30, the preliminary guiding positioning can be completed before the lower water chamber 2 is lifted and lowered, avoiding the need to adjust the horizontal position of the lower water chamber 2 when the lower water chamber 2 is lifted to the mid-air, or even when it is about to be docked with the oil cooler body 3, to achieve the docking of the corresponding first bolt hole 201 and the second bolt hole 301, avoiding the process of lifting the lower water chamber 2 in the mid-air and slowly docking during the manual lifting process, further improving the working efficiency and reducing the consumption of manpower.

[0046] Specifically, Figure 1 and Figure 2 As shown, the base 10 includes a base body 11 and at least one movable wheel 12 arranged on the base body 11. The at least one movable wheel 12 can rotate relative to the placement surface and jointly support the base body 11 to support the base body 11 away from the placement surface. In this way, through the setting of at least one movable wheel 12, the base 10 can be conveniently moved by pushing and pulling. In the process of inserting the guide rope 32 for preliminary guiding, the base 10 can be pushed to achieve the movement and adjustment of the position, avoiding manual transportation of the motor oil cooler lower water chamber disassembly and assembly platform 1, further reducing manpower consumption and improving work efficiency.

[0047] In this embodiment, the base body 11 is in a rectangular parallelepiped shape, and there are four moving wheels 12 , which are respectively disposed on four corners of the lower end of the base body 11 .

[0048] In some other optional embodiments, the base body 11 can also be a structure of other shapes such as a cylinder, a prism, a runway, etc., and the number of the moving wheels 12 can be one, two, three, etc., and it can also be set at other positions of the base body 11.

[0049] In this embodiment, the moving wheel 12 is a universal wheel that can be positioned and fixed. The universal wheel can adopt the existing technology.

[0050] In some other optional embodiments, the moving wheel 12 may also adopt other moving wheel structures such as a one-way wheel, a rolling wheel, and a roller wheel.

[0051] In some embodiments, the base 10 also includes at least one positioning component (not shown in the figure), which is movably disposed on the base body 11 and is used to position the base body 11 when disassembling and assembling the lower water chamber 2, so as to prevent the moving wheel 12 from moving and driving the lower water chamber 2 to move, resulting in the lower water chamber 2 and the oil cooler body 3 being unable to correspond.

[0052] The positioning component includes a positioning state and a free state. When it is in the positioning state, the positioning component is connected to the seat body 11 and the placement surface respectively, so that the base 10 is switched to a fixed state, that is, the relative positioning between the seat body 11 and the placement surface is achieved by connecting the positioning component to the placement surface, avoiding movement, thereby avoiding hidden dangers such as operational errors and damage to equipment caused by the malfunction of the motor oil cooler lower water chamber disassembly and assembly platform 1 during the lower water chamber disassembly and assembly operation. When it is in a free state, the positioning component is connected to the seat body 11 and separated from the placement surface, so that the base is switched to a movable state. At this time, the base 10 is movably arranged to facilitate the convenient movement of the motor oil cooler lower water chamber disassembly and assembly platform 1 to a target location such as a storage place, reducing the workload of operators such as carrying.

[0053] Specifically, the positioning assembly includes a supporting positioning member and a connecting rod. One end of the connecting rod is rotatably connected to the base body 11 for easy storage, and the other end is formed with a clearance hole, and the supporting positioning member is movably inserted into the clearance hole. When the positioning assembly is in a positioning state, the end of the supporting positioning member away from the connecting rod (that is, the lower end of the supporting positioning member) is connected to the placement surface so that the base 10 is switched to a fixed state. When the positioning assembly is in a free state, the end of the supporting positioning member away from the connecting rod (that is, the lower end of the supporting positioning member) is separated from the placement surface so that the base is switched to a movable state.

[0054] In this embodiment, the number of the positioning components is four, and two groups of two are respectively arranged on the two opposite side walls of the base 11, and the two positioning components of each group are respectively arranged at the two ends of the side walls where they are located. A through hole is formed at one end of the connecting rod at a position corresponding to the base 11, and the connecting rod and the base 11 are rotatably connected by passing through bolts, pins and other connecting parts. The supporting positioning member is a threaded rod, the lower end of which is a conical foot cup shape, and the upper end is a rotating wheel structure that is convenient for manual rotation operation. The clearance hole at the other end of the connecting rod is a threaded hole. By rotating the rotating wheel, the threaded rod can be moved up and down in the threaded hole, and then the supporting positioning member can be movably passed through the clearance hole.

[0055] In some other optional embodiments, the connecting rod may not be provided, and the positioning of the seat body 11 may be achieved by directly passing the supporting positioning member through the seat body 11.

[0056] In some embodiments, the base 10 further includes an armrest 13 , which is erected at one end of the base 11 , and is used to push the base 11 through the armrest 13 when the positioning assembly is in a free state.

[0057] In some embodiments, the driving component 21 is a hydraulic scissors fork, and the two ends (i.e., the upper and lower ends) of the hydraulic scissors fork are respectively fixed to the lifting platform 22 and the seat body 11, and the lifting platform 22 is lifted relative to the seat body 11 through its own hydraulic extension and retraction.

[0058] In some other optional embodiments, the driving component 21 may also be a hydraulic rod (telescopic column), a pneumatic rod (telescopic column) or other structures.

[0059] In this embodiment, the lifting platform 22 is in the shape of a rectangular plate.

[0060] In some other optional embodiments, the lifting platform 22 may also be a structure of other shapes such as a cylinder, a prism, or a runway.

[0061] In some embodiments, the lifting platform 22 includes a platform body 221 and at least one stopper 222 disposed on the platform body 221. The platform body 221 is connected to the driving component 21 and can be lifted and lowered relative to the base 10 under the drive of the driving component 21. The stopper 222 defines a receiving space 2221 for receiving the lower water chamber 2. During the disassembly and assembly process, the lower water chamber 2 can be limited in the receiving space 2221.

[0062] In this embodiment, there are three limit members 222, all of which are columnar in shape and erected on the platform body 221, with even spacing between each other. In this way, the accommodating space 2221 defined by the three limit members 222 is columnar, so that the main body of the lower water chamber 2 can be accommodated in the accommodating space 2221. At the same time, the connecting flange of the lower water chamber 2 is clamped on the upper end surfaces of the three limit members 222, thereby realizing the limitation of the lower water chamber 2.

[0063] In some other optional embodiments, the limiting member 222 may be provided in one, two or four forms. When it is provided in one form, its structure may be that the upper end surface is recessed to form an accommodating space 2221, or it may be provided in a cylindrical shape.

[0064] In some embodiments, a buffer layer is provided on the upper end surface of the limiting member 222 to avoid direct hard contact between the limiting member 222 and the connecting flange of the lower water chamber 2, thereby effectively reducing the risk of damaging the structure of the lower water chamber 2.

[0065] In this embodiment, the buffer layer is brass, which is a soft material.

[0066] In some embodiments, the guide rope 32 includes a rope body, a screw rod and at least one locking nut (not shown in the figure), the rope body is wound on a drum (31), the screw rod is arranged at the free end of the rope body, and the locking nut is movably arranged on the screw rod and is used to relatively fix the free end of the guide rope 32 to the side of the second bolt hole 301 away from the first bolt hole 201, that is, the guide rope 32 is passed through and relatively positioned in the lower water chamber 2 and the oil cooler body 3.

[0067] It should be understood that the free end of the rope refers to the end of the rope extending from the drum 31 and passing through the first bolt hole 201 and the second bolt hole 301 .

[0068] In this embodiment, there are two locking nuts, which are respectively used to be fixed on both sides of the second bolt hole 301 , that is, to fix the free end of the guide rope 32 on the oil cooler body 3 .

[0069] In some other optional embodiments, the guide rope 32 may not be provided with a screw rod and a locking nut. The above effect can also be achieved by tying a knot on the side of the second bolt hole 301 away from the first bolt hole 201 after the guide rope 32 is passed through the second bolt hole 301.

[0070] like Figure 2 and Figure 3As shown, in some embodiments, the guide assembly 30 further includes at least one steering pulley for changing the extending direction of the guide rope 32. The steering pulley is arranged on the platform body 22, and there is at least one steering pulley, so that the free end of the guide rope 32 can coincide with the axis of the first bolt hole 201 and the second bolt hole 301 through the steering of the steering pulley, that is, perpendicular to the platform body 221. To ensure that the extending direction of the guide rope 32 is parallel to the axis of the first bolt hole 201 and the second bolt hole 301, and to avoid bending of the guide rope 32 at the end of the first bolt hole 201 and / or the second bolt hole 301 when passing through the first bolt hole 201 and / or the second bolt hole 301.

[0071] In some embodiments, the number of the guide ropes 32 is at least two, and the circumscribed circle of the figure defined by all the guide ropes 32 is coaxially arranged with the accommodating space 2221 .

[0072] It should be understood that the figure defined by the guide rope 32 refers to the figure defined by the connecting lines between the points of the guide rope 32 under a certain horizontal cross section.

[0073] By providing at least two guide ropes 32 and arranging the circumscribed circle of the figure defined by the guide ropes 32 coaxially with the accommodating space 2221, it can be ensured that during the initial guiding and lifting process, the force applied to the oil cooler body 3 by the guide ropes 32 is uniform, thereby effectively reducing the risk of stress damage to the oil cooler body 3 caused by concentrated tension at a certain point.

[0074] It should be understood that when the number of the guide ropes 32 is at least two, the number of the diverting pulleys should also be at least two, and each guide rope 32 should correspond to at least one diverting pulley to ensure that its free end extends vertically.

[0075] In this embodiment, there are two guide ropes 32, and three steering pulleys are provided for each guide rope 32. They are defined as a first steering pulley 33, a second steering pulley 34, and a third steering pulley 35. The first steering pulley 33 makes the free end of the guide rope 32 turn perpendicular to the platform body 221. The second steering pulley 34 is provided between the first steering pulley 33 and the third steering pulley 35, and the third steering pulley 35 is provided between the second steering pulley 34 and the drum 31. The provision of the second steering pulley 34 and the third steering pulley 35 can relieve the stress on the guide rope 32.

[0076] Specifically, Figure 4As shown, the first steering pulley 33 includes a first bracket 331 and a first pulley body 332. The first bracket 331 is U-shaped with an opening facing upward and is vertically fixed on the platform body 221. The first pulley body 332 is vertically arranged in the first bracket 331, so that the pulley body 332 can transform the originally horizontally extended guide rope 32 into a vertical extension, thereby achieving an effect of being parallel to the axis of the first bolt hole 201 and the second bolt hole 301.

[0077] like Figure 5 As shown, the second diverting pulley 34 includes a second bracket 341, a second pulley body 342, a fixing member 343, a moving rod 344, a spring 345 and a receiving member 346. The fixing member 343 is fixed to the platform body 221, and the receiving member 346 is arranged in a columnar shape, fixed to the fixing member 343 in the horizontal direction, and then fixed relative to the platform body 221. The receiving member 343 has an open end and a closed end, and a through hole is formed on the wall surface of the closed end, and the moving rod 344 is movably inserted into the through hole. The spring 345 is sleeved on the moving rod 344, and one end is fixed to one end of the moving rod 344, and the other end is fixed in the receiving member 346. The end of the spring 345 fixed to the moving rod 344 extends out of the receiving member 343 and is fixed to the second bracket 341. The second bracket 341 is U-shaped, and its opening is horizontally disposed. The second pulley body 342 is horizontally rotatably disposed in the second bracket 341 .

[0078] like Figure 6 As shown, the third diverting pulley 35 includes a third bracket 351 and a third pulley body 352, wherein the third bracket 351 is in a square shape and is horizontally arranged on the platform body 221, so that the guide rope 32 extending from the drum 31 passes through the third bracket 351. The third pulley body 352 is horizontally rotatably arranged in the third bracket 351.

[0079] In this embodiment, the two third diverting pulleys 35 corresponding to the two guide ropes 32 share a third bracket 351 , that is, there are two third pulley bodies 352 , which are respectively disposed in the third bracket 351 .

[0080] Since in this embodiment, there is only one reel 31, two guide ropes 32 are respectively wound in the reel 31. However, since the vertical extension position of the free end of the guide rope 32 needs to satisfy the coaxial arrangement of the circumscribed circle of the defined figure and the accommodating space 2221, the two first diverting pulleys 33 need to be respectively arranged on two opposite sides of the accommodating space 2221. At this time, when the reel 31 outputs the guide rope 32 to the first diverting pulley 33, it is difficult to avoid the guide rope 32 from bending at the reel 31 or at the first diverting pulley 33, and it is subjected to unnecessary stress and easily damaged. The arrangement of the second diverting pulley 34 and the third diverting pulley 35 can effectively avoid the bending of the guide rope 32, provide a guiding buffer for the change of direction of the guide rope 32, and thus avoid the unnecessary stress generated by the guide rope 32, the reel 31 and the first diverting pulley 33 during the retraction and release process, thereby extending the service life of the equipment.

[0081] In some other optional embodiments, the number of the drums 31 can also be set to correspond to the number of guide ropes 32, so that each drum corresponds to a guide rope 32, thereby reducing the number of steering pulleys to be set.

[0082] In this embodiment, the guide rope 32 is a Kevlar rope, which has good force-bearing performance and is sufficient to bear the weight of the lower water chamber 2 and the motor oil cooler lower water chamber disassembly and assembly platform 1 itself.

[0083] In some embodiments, the motor oil cooler lower water chamber disassembly and assembly platform 1 further includes a control module for controlling the operation of the entire motor oil cooler lower water chamber disassembly and assembly platform 1. The control module includes a drive component control unit 41, a reel control unit 42, and a main control board. Among them, the drive component control unit is used to control the extension and lifting of the drive component 21. The reel control unit 42 is used to control the rotation, stop, rotation direction, etc. of the reel 31. The main control board is used to control the speed of the drive component 21 and the reel 31 to ensure that the speed between the two is consistent.

[0084] like Figure 7As shown, the driving component control unit 41 includes an oil tank 411, a first motor 412, an oil pump 413, a one-way throttle valve 414, a one-way valve 415, and a relief valve 417. The first motor 412 is electrically connected to the oil pump 413, and is used to drive the oil pump 413 to operate. The driving component 21 is connected to the oil tank 411, and the oil pump 413 is arranged between the driving component 21 and the oil tank 411, and is used to pump the hydraulic oil in the oil tank 411 to the driving component 21. The one-way valve 415, the solenoid valve 41 and the one-way throttle valve 414 are arranged between the oil pump 413 and the oil tank 411, and the one-way valve 415 is arranged upstream of the solenoid valve 416, and the solenoid valve 416 is arranged upstream of the one-way throttle valve 414. The relief valve 417 is connected to the pipeline between the one-way valve 415 and the oil pump 413 through a pipeline. The solenoid valve 416 and the overflow valve 417 are both electrically connected to the main control board at one end and grounded at the other end.

[0085] like Figure 8 As shown, the reel control unit 42 includes a second motor 421, a battery 422, a voltmeter 423, a circuit breaker KB, a first contactor KM1, a second contactor KM2, a first fuse KM3, a second fuse KM4, a first button switch Q1, a second button switch Q2 and a charger 424. The first end of the second motor 421 is connected to the first end of the first contactor KM1, and the second end is connected to the first end of the second contactor KM2. The second end of the first contactor KM1 is electrically connected to the positive electrode of the battery 422, the first end of the voltmeter 423 and the first end of the circuit breaker KB, and the second end of the second contactor KM2 is connected to the negative electrode of the battery 422, the second end of the voltmeter 423, the first fuse KM3 and the second end of the second fuse KM4. The second end of the circuit breaker KB is electrically connected to the first end of the first button switch Q1 and the first end of the second button switch Q2, respectively. The first end of the first button switch Q1 is electrically connected to the first end of the first fuse KM3, and the second end of the second button switch Q2 is electrically connected to the first end of the second fuse KM4. The positive and negative electrodes of the battery 422 are also detachably electrically connected to the charger 424.

[0086] In some embodiments, the second motor 421 is disposed on the platform body 221, and its output shaft is connected to the reel 31. The base 10 further includes a control box (not shown), which is disposed on the base body 11. Other components of the control module are disposed in the control box.

[0087] In this embodiment, the control box is disposed on one side of the base 11 where the armrest 13 is located, erected on the base 11 , and connected to the armrest 13 .

[0088] In some other optional embodiments, the control box may also be horizontally disposed on an upper end surface of one side of the base body 11 , or disposed at a lower end portion of the base body 11 .

[0089] In some embodiments, the first motor 412, the second motor 421, the one-way throttle valve 414, the solenoid valve 416 and the overflow valve 417 are electrically connected to the main control board, respectively. The output power of the first motor 412 and the second motor 421, as well as the opening and closing degree of the one-way throttle valve 414 are controlled by the main control board, thereby controlling the lifting speed of the driving component 21 to match the rolling speed of the drum 31, ensuring that the guide rope 32 is always in a straightened state. Even if the first motor 412 suddenly loses driving force, the drum 31 driven by the second motor 421 can still make the guide rope 32 pull the oil cooler body 3, stabilize itself, and play a safety role.

[0090] In some embodiments, the control module further includes an operation panel (not shown in the figure), which is electrically connected to the main control board and is used to control the running direction and start and stop of the driving component 21 and the reel 31.

[0091] In this embodiment, the operation panel is arranged at the upper end of the control box for the convenience of operators.

[0092] In the specific use process, the motor oil cooler lower water chamber disassembly and assembly platform 1 first needs to be moved to the bottom of the lower water chamber 2 by the moving wheel 12, and the free end of the guide rope 32 is inserted into the first bolt hole 201 and the second bolt hole 301, and the locking nut is set at the end of the second bolt hole 301 away from the first bolt hole 201 by the screw rod. At this time, according to the situation of the guide rope 32 in the two bolt holes, the position of the motor oil cooler lower water chamber disassembly and assembly platform 1 is further adjusted by the moving wheel 12 until the extension direction of the vertical part of the guide rope 32 is parallel to the axis of the first bolt hole 201 and the second bolt hole 301.

[0093] Furthermore, the connecting rods of the several positioning components are rotated respectively to form a certain angle or be perpendicular to the side wall of the seat body 11. The supporting positioning member is rotated until the supporting positioning member contacts the placement surface to achieve the positioning of the base 10.

[0094] Furthermore, the driving component 21 is lifted by operating the operating panel, and the reel 31 rotates at the same time, and the guide rope 32 is recovered synchronously until the lower water chamber 2 falls into the accommodating space 2221.

[0095] Furthermore, all bolts between the oil cooler body 3 and the lower water chamber 2 are removed.

[0096] Furthermore, the driving component 21 is lowered by operating the operating panel, and the reel 31 rotates at the same time, and the guide rope 32 is released synchronously until the driving component 21 is completely lowered to the lowest state.

[0097] Further, the locking nut is removed, the guide rope 32 is recovered in the reel 31, and the positioning assembly is recovered. At this time, the removed lower water chamber 2 can be brought to the target position by the moving wheel 12 for maintenance and other operations.

[0098] During the assembly process, just follow the reverse steps.
