[0001] The present invention relates to the technical field of truck-mounted cranes, and specifically relates to a multifunctional truck-mounted lifting device. Background Art

[0002] The official name of a truck-mounted crane: a truck-mounted crane and transporter. It is widely applicable to the hoisting and transportation of infrastructure materials and other equipment in municipal construction, coal mine engineering, landscaping, etc. The truck-mounted crane can be operated left and right, rotated 360 degrees forward and backward, or rotated omnidirectionally. It is produced with military quality, reliable in quality, long in service life, and fast in working speed.

[0003] In existing coal mines, it is often necessary to perform hoisting operations on items of various shapes, sizes, and positions, and accurately move slender objects such as pipelines to designated positions for installation. Most traditional hoisting methods rely on manual operation, which is not only inefficient but also poses a high safety risk. Especially when dealing with heavy or irregularly shaped objects, direct manual operation is extremely likely to cause accidents, seriously affecting the safety of operators. Therefore, a multifunctional truck-mounted lifting device is proposed. Summary of the Invention

[0011] Preferably, two third hydraulic cylinders are hinged to the outside of the connecting frame. The push rod end of the third hydraulic cylinder is hinged to one side of the claw, and one side of the claw is hinged to one side of the connecting frame.

[0012] Preferably, the push rod end of the first hydraulic cylinder is hinged to one side of the bottom of the first support arm, and the push rod end of the second hydraulic cylinder is fixed to one side of the second support arm.

[0013] Preferably, the number of the claws is two, and the two claws are arranged oppositely.

[0014] Preferably, the connecting component includes two fixing frames. Chutes and limiting grooves are respectively formed inside the fixing frames, and a sliding plate is slidably connected to the inner side of the chute.

[0015] Preferably, a limiting rod is fixed to one side of the rubber plate, and a locking groove is formed on one side of the limiting rod.

[0016] Preferably, a locking rod is fixed to one side of the sliding plate.

[0019] Compared with the prior art, the present invention adopts the above technical solutions and has the following technical effects:

[0020] 1. By controlling the first hydraulic cylinder and the second hydraulic cylinder to extend different lengths, the lifting hook can be in different positions, which can meet the lifting requirements of items with different shapes, sizes and positions. The mechanized lifting method reduces the risk of direct manual operation, avoids accidents during the lifting process, and improves the safety of the operation.

[0021] Second, by controlling the output shaft of the slewing speed reducer to drive the connecting arm to rotate, the position of the claw can be flexibly adjusted, enabling it to conveniently rotate to the side of the second support arm.

There is no need for workers to manually perform heavy lifting and handling work, greatly reducing the labor intensity of workers and ensuring the accuracy and efficiency of pipeline installation.

[0022] Third, by setting a rubber plate between the claw and the pipeline, direct contact between the claw and the pipeline can be effectively avoided, preventing damage such as scratches and abrasions to the pipeline surface during the lifting process, thus ensuring that the appearance and performance of the pipeline are not affected and improving the installation quality and service life of the pipeline.

[0023] Fourth, by pulling the pull block, a series of actions such as moving and unlocking the sliding plate are realized, and the worn rubber plate can be quickly removed. By using common and simple mechanical structures such as sliding rods, sliding plates, springs, locking rods, locking grooves, limiting rods, and limiting grooves, the stable installation and convenient replacement of the rubber plate are achieved. It is easy to understand and maintain, with high stability, reducing the risk of failures caused by complex structures. When installing a new rubber plate, the installation can also be completed through simple insertion, pulling, and releasing actions, greatly shortening the time and effort required for replacing the rubber plate and improving work efficiency.

[0036] One side of the vertical arm 5 is hinged with a first hydraulic cylinder 6, and the first hydraulic cylinder 6 is used to adjust the lifting angles of the first support arm 4 and the second support arm 10; a second hydraulic cylinder 7 is installed on one side of the first support arm 4, and the second hydraulic cylinder 7 is used to adjust the extending position of the hook 8; a slewing speed reducer 11 is fixed on one side of the second support arm 10, a connecting arm 12 is fixed at the output shaft end of the slewing speed reducer 11, a claw 16 for gripping an article is provided on one side of the connecting arm 12, and a rubber plate 2 is provided on the inner wall of the claw 16. The rubber plate 2 can effectively prevent the claw 16 from directly contacting the pipeline, and prevent scratches, abrasions and other damages to the pipeline surface during the lifting process;

[0037] One end of the connecting arm 12 is fixed with a swing oil cylinder 13 for adjusting the angle of the claw 16. The output end of the swing oil cylinder 13 is fixed with a connecting frame 14. Two third hydraulic cylinders 15 are hinged on the outside of the connecting frame 14. The push rod ends of the third hydraulic cylinders 15 are hinged to one side of the claw 16. The push rod ends of the third hydraulic cylinders 15 extend different lengths, so that different distances are formed between the two claws 16 on both sides, and pipelines with different diameters can be clamped. One side of the claw 16 is hinged to one side of the connecting frame 14. The push rod end of the first hydraulic cylinder 6 is hinged to the bottom side of the first support arm 4. The push rod end of the second hydraulic cylinder 7 is fixed to one side of the second support arm 10. The number of claws 16 is two, and the two claws 16 are arranged opposite to each other.

[0038] A connecting component 3 for disassembling and assembling the rubber plate 2 is provided on one side of the claw 16.

[0039] The connecting component 3 includes two fixing frames 31. Chute 32 and limit groove 36 are respectively formed inside the fixing frames 31. A sliding plate 39 is slidably connected to the inner side of the chute 32. A limiting rod 37 is fixed on one side of the rubber plate 2. A locking groove 38 is formed on one side of the limiting rod 37. A locking rod 312 is fixed on one side of the sliding plate 39. Pull the pull block 34 to one side, the pull block 34 drives the sliding rod 33 and the sliding plate 39 to move to one side, the sliding plate 39 compresses the spring 310, and at the same time makes the locking rod 312 leave the inside of the locking groove 38. When the locking rod 312 is inserted into the inside of the locking groove 38, the rubber plate 2 and the claw 16 are in a connected state. When the locking rod 312 leaves the inside of the locking groove 38, the rubber plate 2 and the claw 16 are in a separated state. Pull the rubber plate 2 downward so that the limiting rod 37 leaves the limiting groove 36 and inserts into the insertion groove 311 in sequence. At this time, the damaged rubber plate 2 can be removed.

[0040] The surface of the sliding plate 39 is provided with ventilation holes 35. A sliding rod 33 that movably penetrates through one side of the fixing frame 31 is fixed to the side of the sliding plate 39 away from the locking rod 312. A pulling block 34 is fixed to one end of the sliding rod 33. A spring 310 is sleeved on the outer side of the sliding rod 33. The limiting rod 37 is inserted into the inner side of the insertion groove 311. When the limiting rod 37 is located at the bottom of the locking rod 312, the pulling block 34 is pulled, and the rubber plate 2 is further pushed upward, so that the locking groove 38 is located on one side of the locking rod 312. The two sides of the spring 310 are respectively connected to the sliding groove 32 and one side of the sliding plate 39. An insertion groove 311 for inserting the limiting rod 37 is formed on one side of the claw 16. One side of the fixing frame 31 is fixed to one side of the claw 16. The pulling force on the pulling block 34 is released. At this time, under the elastic force of the spring 310, the locking rod 312 is pushed to be inserted into the inner side of the locking groove 38, and at this time, the installation of the rubber plate 2 is completed.

[0041] Working principle: A slewing reducer is installed at the installation position of the vehicle body. The bottom of the base 1 is connected to the slewing reducer of the vehicle body. When lifting or grasping an object, the vehicle body is moved to one side of the object to be lifted or grasped. By controlling the first hydraulic cylinder 6 and the second hydraulic cylinder 7 to extend different lengths, the hook 8 can be in different positions. And the winch 9 works to release the steel wire rope, connecting the object to the hook 8. The first hydraulic cylinder 6 and the second hydraulic cylinder 7 are controlled to retract, and at the same time the winch 9 winds the steel wire rope together, so that the object on one side of the hook 8 is lifted. When the object moves to the upper side of the hopper, the winch 9 releases the steel wire rope, so that the object lifted by the hook 8 is placed inside the hopper, realizing the transportation of materials.

[0042] When it is necessary to grasp and install the pipeline, only need to control the output shaft of the slewing reducer 11 to drive the connecting arm 12 to rotate. The connecting arm 12 drives the claw 16 to rotate to one side of the second support arm 10. Under the action of the first hydraulic cylinder 6 and the second hydraulic cylinder 7, the claw 16 is moved to one side of the pipeline. Then the push rod end of the third hydraulic cylinder 15 retracts. Under the action of the swing cylinder 13, the claw 16 clamps the pipeline. At this time, the rubber plate 2 is located between the claw 16 and the pipeline, avoiding direct contact between the claw 16 and the pipeline and causing damage to the surface of the pipeline. Moving the pipeline to different positions can perform installation operations on the pipeline, realizing the mechanized operations of grasping and installing the pipeline, reducing the labor intensity of workers and improving the operation safety.

[0043] When the rubber plate 2 is used for a long time and the surface of the rubber plate 2 is worn, only need to pull the pulling block 34 to one side. The pulling block 34 drives the sliding rod 33 and the sliding plate 39 to move to one side. The sliding plate 39 compresses the spring 310, and at the same time makes the locking rod 312 leave the inner side of the locking groove 38. At this time, the damaged rubber plate 2 can be removed by pulling the rubber plate 2 downward so that the limiting rod 37 sequentially leaves the inner sides of the limiting groove 36 and the insertion groove 311.

[0044] Take a new rubber plate 2, insert the limit rod 37 inside the insertion groove 311, so that when the limit rod 37 is at the bottom of the lock rod 312, pull the pull block 34, and continue to push the rubber plate 2 upward, so that the lock groove 38 is on one side of the lock rod 312. At this time, release the pulling force on the pull block 34. At this time, under the elastic force of the spring 310, push the lock rod 312 to insert into the inside of the lock groove 38, and at this time, the installation of the rubber plate 2 is completed.

[0045] In summary, by controlling the first hydraulic cylinder 6 and the second hydraulic cylinder 7 to extend different lengths, the lifting hook 8 can be in different positions, which can meet the lifting requirements of items with different shapes, sizes and positions. The mechanized lifting method reduces the risk of direct manual operation, avoids accidents during the lifting process, and improves the safety of the operation.

[0046] By controlling the output shaft of the slewing reducer 11 to drive the connecting arm 12 to rotate, the position of the claw 16 can be flexibly adjusted, so that it can be conveniently rotated to one side of the second support arm 10. Cooperating with the third hydraulic cylinder 15 and the swing cylinder 13, the claw 16 can be accurately moved to a suitable position to clamp the pipeline, and the pipeline can be moved to different positions for installation operations, without the need for workers to manually perform heavy lifting and handling work, greatly reducing the labor intensity of workers and ensuring the accuracy and efficiency of pipeline installation.

[0047] By arranging the rubber plate 2 between the claw 16 and the pipeline, it can effectively prevent the claw 16 from directly contacting the pipeline, and prevent scratches, abrasions and other damages to the pipeline surface during the lifting process, so as to ensure that the appearance and performance of the pipeline are not affected, and improve the installation quality and service life of the pipeline.

[0048] By pulling the pull block 34, a series of actions such as the movement and unlocking of the sliding plate 39 are realized, and the worn rubber plate 2 is quickly removed. By using common and simple mechanical structures such as the sliding rod 33, the sliding plate 39, the spring 310, the lock rod 312, the lock groove 38, the limit rod 37 and the limit groove 36, the stable installation and convenient replacement of the rubber plate 2 are realized, which is easy to understand and maintain, has high stability, reduces the risk of failure caused by complex structures. When installing a new rubber plate 2, the installation can also be completed through simple insertion, pulling and releasing actions, greatly shortening the time and effort required to replace the rubber plate 2 and improving the work efficiency.
