Description

Technical Field

[0001] The invention relates to the technical field of lifting equipment, in particular to a winch type hose hoist. Background Art

[0002] A capstan hose crane is a device that uses the winch principle for lifting operations. It winds and releases the hose through a drum and a drive device (such as an electric motor, manpower or hydraulic power), thereby achieving the function of lifting and moving heavy objects. The basic principle of a capstan hose crane is to use ropes, steel cables or other similar materials as lifting media, and to wind and release these media through a drum set in a fixed position. The drive device provides power to rotate the drum, thereby lifting or moving heavy objects.

[0003] In the prior art, when a winch-type hose hoist is in use, a hook is usually used to fix and hang one end of the hose to be moved for transportation. During the lifting process, the other end of the hose is not limited and fixed, which may cause it to swing due to moving inertia or external force factors. When the lifted hose is then docked for use, the swing at the pipe interface will directly cause the flange end face to be not perpendicular to the pipe axis, making it impossible for the joint surface to fit tightly, thereby causing medium leakage problems that affect its subsequent use effect. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a winch-type hose hoist to solve the problems raised in the above-mentioned background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A capstan type hose hoist, comprising a base platform, a top surface of the base platform is rotatably connected to a boom, a bottom surface of the boom is provided with a support column, an electric winch is fixedly installed on the top surface of the boom, a main steel cable is wound around the inside of the electric winch, a main hook is fixedly installed on one end of the main steel cable, a first hydraulic rod is fixedly installed on one side of the base platform, and one end of the first hydraulic rod is rotatably connected to the boom; The two sides of the base platform are respectively fixedly installed with slide rails, the interior of the slide rails is slidably connected with a slider, one side of the slider is fixedly installed with a connecting plate, the interior of the connecting plate is rotatably connected with a second adjusting rod, one end of the second adjusting rod is rotatably connected with the first adjusting rod, one end of the first adjusting rod is fixedly installed with a mounting head, the top surface of the mounting head is fixedly installed with a positioning cover, the interior of the positioning cover is rotatably connected with two limiting wheels, an auxiliary steel cable is arranged between the two limiting wheels, and one end of the auxiliary steel cable is fixedly installed with an auxiliary hook; The bottom surface of the boom is provided with a driving assembly, and is used to drive the two auxiliary steel cables to be retracted and released; The bottom surface of the boom is provided with an adjustment component for adjusting the use angles of the two first adjustment rods.

[0006] By adopting the above technical solution, when in use, the staff uses the adjustment component and the drive component according to the length of the hose to be lifted, so that the two auxiliary steel cables are released, and the two first adjustment rods are rotated and opened, and then the drive component is continued to be used to release the two auxiliary steel cables, and then the auxiliary hook will sag to the same height as the main hook under the weight of the auxiliary hook, so as to calibrate the use height of the two auxiliary hooks and the main hook. After the above steps are completed, the staff hangs the main hook on the middle part of the hose, and hangs the two auxiliary hooks on the two ends of the hose respectively, and then the staff lifts the boom through the first hydraulic rod, and at the same time, the two auxiliary steel cables drive the auxiliary hooks to move up through the drive component to adjust the height of the two ends of the hose, and the second protective cover shrinks the main steel cable to make the main hook rise, so as to complete the lifting of the hose. In this process, since the use spacing of the two auxiliary hooks can be adjusted according to the length of the hose, and since both ends of the hose are limited to a certain extent during the lifting process, the swing of the hose at both ends during lifting can be reduced, and the axis deviation effect can be prevented during subsequent docking and use.

[0008] By adopting the above technical solution, when the staff uses the two auxiliary hooks, the staff starts the driving motor, and the rotation of the driving shaft of the driving motor will drive the active transmission teeth to rotate, and then under the tooth meshing transmission action of the active transmission teeth and the driven transmission teeth, the two active sprockets will rotate accordingly. At this time, under the chain transmission action of the active sprocket, the transmission chain and the driven sprocket, the two driven sprockets will respectively drive the two storage wheels to rotate, and then the rotation of the storage wheel will reel in or release the auxiliary steel cable inside it, thereby achieving the effect of driving the two auxiliary hooks.

At this time, since the inner walls of the two slide rails are both inclined surfaces, the sliding of the slider will cause the connecting plate to drive the second adjusting rod to rotate, and then the rotating second adjusting rod will push the first adjusting rod to rotate. At this time, the use spacing of the two first adjusting rods will open away from each other, and then the mounting heads at one end of the two first adjusting rods will drive the positioning cover at the top and the auxiliary steel cable inside the limiting wheel to move, so that the use spacing of the two auxiliary hooks can be adjusted.

A steel wire rope 27 is wound around the inside of the take-up wheel 25, and one end of the steel wire rope 27 is fixedly installed with a mounting head 46. When the two first adjusting rods 13 drive the two mounting heads 46 to move, the mounting head 46 will pull the steel wire rope 27, and then the pulled steel wire rope 27 will drive the take-up wheel 25 to rotate. At this time, the steel wire rope 27 can be used to adjust the mounting head 46 under the action of the rebound force of the coil spring 26. 6 generates a certain pulling force, so that the use angle of the mounting head 46 can be positioned to prevent it from being offset and causing the auxiliary steel cable 18 inside it to fall off. One side of the mounting head 46 is rotatably connected to a tensioning seat 49, and the inside of the tensioning seat 49 is rotatably connected to two tensioning wheels 28.

The mounting sleeve 32 is rotatably connected to two positioning wheels 33 inside, which is convenient for limiting the position of the auxiliary steel cable 18 when it is retracted and released to prevent the auxiliary steel cable 18 from falling off between the secondary steel cable 18 and the storage wheel 39. Mounting plates 20 are fixedly installed on both sides of the boom 2. A connecting rod 30 is rotatably connected to one side of the mounting plate 20. The connecting rod 30 One end of the boom 2 is rotatably connected to a pressure wheel 31, and a first elastic telescopic rod 29 is fixedly installed on one side of the mounting plate 20. One end of the contraction rod of the first elastic telescopic rod 29 is fixedly installed to the connecting rod 30, and the pressure wheel 31 is driven by the resilience of the first elastic telescopic rod 29 to squeeze the wire rope 27, so that the wire rope 27 maintains a certain tension to prevent the wire rope 27 from falling off from the inside of the take-up wheel 25.

At this time, the two ends and the middle of the hose are fixed by the main hook 4 and the two auxiliary hooks 19, and then the driving shaft of the driving motor 44 is reversed through the controller inside the control box, thereby driving the two storage wheels 39 to reel in the two auxiliary steel cables 18. At the same time, the electric winch 11 is used to reel in the main steel cable 3 through the controller of the base platform 1, so that the two auxiliary hooks 19 and the main hook 4 can simultaneously drive the hose to rise, so that the hose can be initially lifted. At this time, the first hydraulic rod 6 is used by the controller to make its telescopic rod drive the boom 2 to rotate, thereby completing the further lifting of the hose.

[0037] Working principle: Please refer to Figure 1-Figure 11 As shown, when in use, the staff uses the adjustment assembly and the driving assembly according to the length of the hose to be lifted, so that the two auxiliary steel cables 18 are released, and the two first adjustment rods 13 are rotated and opened, and then the driving assembly is continued to be used to release the two auxiliary steel cables 18, and then under the action of the weight of the auxiliary hook 19, the auxiliary hook 19 will sag to the same height as the main hook 4, so as to calibrate the use height of the two auxiliary hooks 19 and the main hook 4. After the above steps are completed, the staff hangs the main hook 4 on the middle part of the hose, and hangs the two auxiliary hooks 19 on both ends of the hose respectively. Then the staff lifts up the boom 2 through the first hydraulic rod 6, and at the same time drives the two auxiliary steel cables 18 to move the auxiliary hooks 19 upward through the driving assembly to adjust the height of the two ends of the hose, and the second protective cover 10 contracts the main steel cable 3 to raise the main hook 4, so as to complete the lifting of the hose. In this process, the use spacing of the two auxiliary hooks 19 can be adjusted according to the length of the hose. At the same time, since the two ends of the hose are limited to a certain extent during the lifting process, the swing of the two ends of the hose during lifting can be reduced, and the axis deviation can be prevented during subsequent docking and use.
