Detailed implementation manner

[0022] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples, and the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0023] Refer to Figures 1 - 4 , the present invention provides a cylinder block detection and lifting device, including a chassis 1. One side of the chassis 1 is fixedly connected with a support frame 2 by bolts to strengthen the stability of the chassis 1. A plurality of symmetrically distributed universal wheels 8 are fixedly connected to the bottom of the chassis 1 by bolts to facilitate the movement of the device. One side of the chassis 1 is rotatably connected with a lever arm 3. One end of the lever arm 3 is provided with a movable head 6 through an adjustment assembly. A mounting ring 7 is provided at the bottom of the movable head 6. Two mounting plates 14 are fixedly connected to the top of the chassis 1 by bolts. A winding roller 10 is rotatably connected between the two mounting plates 14. A pull rope 5 is arranged inside the winding roller 10. The pull rope 5 is a cable, and one end of the pull rope 5 is fixedly connected with the movable head 6. A strut 4 is fixedly connected to the top of the lever arm 3 by bolts. A guide wheel 9 is rotatably connected to the top of the strut 4, and the pull rope 5 is wound above the guide wheel 9 to guide the pull rope 5 and prevent the pull rope 5 from contacting the lever arm 3, thereby improving the service life of the device. One side of the end of the lever arm 3 connected to the chassis 1 is fixedly connected with a second disc 16 through a shaft. One side of the winding roller 10 is fixedly connected with a first disc 12 through a shaft. A limiting mechanism for fixing the first disc 12 and the second disc 16 is provided on one side of the mounting plate 14. When in use, the mounting ring 7 is moved above the engine, and the cable is connected to the mounting ring 7 and the engine. The angle of the lever arm 3 is adjusted to make the distance between the mounting ring 7 and the engine as small as possible. Then, the limiting mechanism is used to fix the position of the lever arm 3. At this time, the engine can be disassembled. After the disassembly is completed, the fixing of the lever arm 3 is unlocked, and an external device is used to drive the winding roller 10 to rotate. The rotation of the winding roller 10 will wind the pull rope 5, thereby lifting the engine. After completely disengaging from the vehicle frame, the limiting mechanism is used to fix the lever arm 3 to maximize the avoidance of engine shaking and improve the protection effect of the device.

[0024] Among them, the adjusting mechanism includes a sliding hole which is opened on one side of the force arm 3. A sliding rod 17 is slidably connected in the sliding hole, and the sliding rod 17 is fixed to the movable head 6. One side of the sliding hole is rotatably connected with a threaded rod 18, and the threaded rod 18 is threadedly connected with the sliding rod 17. A turning handle 19 is key-connected to the circumferential outer wall of the threaded rod 18. When the movable head 6 is not long enough to extend above the engine, rotate the turning handle 19, which drives the threaded rod 18 to rotate, and then makes the sliding rod 17 slide in the sliding hole, so as to extend the length of the force arm 3, enable the movable head 6 to be located above the engine, and improve the applicability of the equipment.

[0025] Among them, the limiting mechanism includes a positioning block 20 and a clamping frame 13. The positioning block 20 is fixed to one side of one of the mounting plates 14 by bolts. The clamping frame 13 is provided with a jack 21, and the positioning block 20 is located in the jack 21. One side of the positioning block 20 is detachably connected with a fixing screw 22 by thread. A plurality of first clamping grooves 11 are opened on the circumferential outer wall of the first disc 12, and a plurality of second clamping grooves 15 are opened on the circumferential outer wall of the second disc 16. The clamping frame 13 is divided into three shapes: convex blocks are provided at both ends and convex blocks are provided at two different ends. When the clamping frame 13 with convex blocks at both ends is clamped into the first clamping groove 11 and the second clamping groove 15, the first disc 12 and the second disc 16 can be fixed, and the angle of the force arm 3 can be fixed doubly. When the clamping frame 13 with a convex block at one end is clamped into the first clamping groove 11, the first disc 12 can be fixed. At this time, only the winding roller 10 is fixed. When the clamping frame 13 with a convex block at one end is clamped into the second clamping groove 15, the second disc 16 can be fixed. At this time, only the force arm 3 is fixed. When one of the fixing effects is damaged, the other fixing can be repaired. The jack 21 is sleeved on the circumferential outer wall of the positioning block 20, and the clamping frame 13 is fixed by using the fixing screw 22. The convex block is clamped into the clamping groove to fix the angle of the force arm 3 and improve the fixing effect of the equipment.

[0026] The working principle of the utility model: When in use, move the mounting ring 7 above the engine, adjust the angle of the force arm 3, and connect the cable to the mounting ring 7 and the engine, so that the distance between the mounting ring 7 and the engine is as small as possible. Drive the winding roller 10 to rotate by using an external device. The rotation of the winding roller 10 will wind up the pulling rope 5, and then lift the engine. After it is completely separated from the vehicle frame, the jack 21 is sleeved on the circumferential outer wall of the positioning block 20, and the clamping frame 13 is fixed by using the fixing screw 22. The convex block is clamped into the clamping groove to fix the angle of the force arm 3. Different clamping frames 13 can produce different fixing effects on the force arm 3, which can avoid the shaking of the engine to the greatest extent and improve the protection effect of the equipment.
