Description

Technical Field

[0001] The utility model relates to the technical field of tower crane dovetail sleeve production, in particular to a descaling device for tower crane dovetail sleeve production. Background Art

[0002] The tower crane dovetail connecting sleeve is a special part for the standard section on the tower crane. It is a component fixedly installed on the standard section to connect the upper and lower standard sections.

[0003] It is a common phenomenon that metal forging products produce oxide scale. Commonly used descaling methods include high-pressure air blowing, scraper scraping, high-pressure sandblasting, rust remover immersion, etc. Among them, high-pressure air blowing and scraper scraping are only applicable to high-temperature forging processes; high-pressure sandblasting and rust remover immersion are often used after quenching and cooling. Since the tower crane dovetail connecting sleeve has a connecting hole structure, it is not convenient to use sandblasting to perform detail processing. Therefore, the most common method for descaling the tower crane dovetail connecting sleeve at room temperature is rust remover immersion.

[0004] In the prior art, when using a rust remover to remove the oxide scale on the surface of the tower crane dovetail connection sleeve, the tower crane dovetail connection sleeve is simply placed in a liquid holding box, and then the rust remover is added to soak and remove the oxide scale. First, since the tower crane dovetail connection sleeve is a metal product with a high density, it will be deposited at the bottom of the rust remover. There is a contact surface between the tower crane dovetail connection sleeves piled together, and the rust remover cannot effectively remove rust and oxide scale from this part; second, some rust removers are harmful to human skin, and the tower crane dovetail connection sleeve is also heavy. Therefore, it is unsafe to use a manual handheld tower crane dovetail connection sleeve to clean the rust remover, which also wastes a lot of manual labor and increases production costs; third, the naturally immersed rust remover cannot form liquid circulation, and the efficiency of removing oxide scale is low. Utility Model Content

[0005] The utility model aims to provide a descaling device for the production of tower crane dovetail sleeves. The descaling of the tower crane dovetail sleeves is carried out by hanging and soaking in a rust remover. The tower crane dovetail sleeves will not form accumulation in the rust remover. The descaling of the tower crane dovetail sleeves is carried out without dead angles, thereby improving operating efficiency and reducing labor costs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a descaling device for producing dovetail sleeves of tower cranes, comprising a rust removal box filled with a rust remover, a hanger is arranged above the rust removal box, and also comprises a first driving mechanism for driving the hanger in and out of the rust removal box, a second driving device for driving the hanger to rotate is arranged between the first driving mechanism and the hanger; a liquid circulation device is also arranged on the rust removal box.

[0007] Preferably, the first driving mechanism is a hydraulic cylinder disposed above the rust removal box.

[0008] Preferably, the second driving device is a swing cylinder.

[0009] Preferably, the hanger comprises a lifting ring, on which a plurality of lifting hooks are arranged.

[0010] Preferably, the lifting ring is fixedly connected to the swing cylinder via a connecting rod.

[0011] Preferably, the hook is arranged in an S-shaped structure, and both ends of the hook form hook-shaped structures.

[0012] Preferably, the top of the lifting ring is provided with a plurality of grooves matching with the lifting hook.

[0013] Preferably, the liquid circulation device comprises a water pump, the liquid inlet of the water pump is connected to the bottom of the rust removal box through a liquid inlet pipe, and the liquid discharge port of the water pump is connected to one side of the rust removal box through a liquid outlet pipe.

[0014] Preferably, a drain pipe is provided at the bottom of the rust removal box.

[0015] Preferably, a plurality of walking wheels are also provided below the rust removal box.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model removes the oxide scale of the dovetail connection sleeve of the tower crane by hanging and soaking the rust remover. The dovetail connection sleeve of the tower crane will not form accumulation in the rust remover, and the oxide scale of the dovetail connection sleeve of the tower crane can be removed without dead angles, thereby improving the descaling efficiency and removal effect, and ensuring the production quality of the dovetail connection sleeve of the tower crane.

[0018] 2. The utility model adopts a mechanical drive method to put the tower crane dovetail connection sleeve into the rust removal box, or take it out from the rust removal box. The operation is simple and easy to use, which greatly reduces manual labor and avoids long-term contact between the rust remover and the staff, causing personal safety problems. At the same time, it also improves the descaling efficiency of the tower crane dovetail connection sleeve and reduces production costs.

[0019] 3. In the utility model, the hanger can rotate in the rust removal box. During the rotation process, the dovetail connecting sleeve of the tower crane increases the relative flow velocity between the rust remover and the dovetail connecting sleeve of the tower crane in the horizontal direction, thereby improving the descaling efficiency. The up and down flow velocity of the rust remover is increased through the liquid circulation device, and the relative flow velocity between the rust remover and the dovetail connecting sleeve of the tower crane in the vertical direction is increased, thereby further increasing the rust removal efficiency.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-5 As shown, a descaling device for producing a tower crane dovetail sleeve comprises a descaling box 1 filled with a rust remover, a hanger 2 for placing a tower crane dovetail connecting sleeve 7 is arranged above the descaling box 1, and also comprises a first driving mechanism for driving the hanger 2 to enter and exit the descaling box 1, and a second driving device for driving the hanger 2 to rotate is arranged between the first driving mechanism and the hanger 2.

[0035] The rust removal box 1 is also provided with a liquid circulation device for internal circulation of the rust removal agent.

[0036] As a specific implementation, the first driving mechanism is a hydraulic cylinder 3 disposed above the rust removal box 1, and the hanger 2 is linked to the driving arm of the hydraulic cylinder 3 through a second driving device.

[0037] Specifically in this embodiment, a second connecting frame 13 extending upward is provided on the top of the rust removal box 1, a supporting frame 14 is provided on the top of the second connecting frame 13, and the hydraulic cylinder 3 is fixed to the top of the supporting frame 14 by bolts.

[0038] As a specific implementation, the second driving device is a swing cylinder 4 , the driving arm of the swing cylinder 4 is cooperatively connected to the hanger 2 , and the driving arm of the hydraulic cylinder 3 is fixedly connected to the swing cylinder 4 .

[0039] Specifically, the swing cylinder 4 is connected to the driving arm of the hydraulic cylinder 3 via a connecting bracket (not shown in the figure).

[0040] As a specific embodiment, the hanger 2 includes a ring-shaped structured lifting ring 21, on which are hung several lifting hooks 25 for hooking the tower crane dovetail connecting sleeve 7, and inside of the lifting ring 21 are arranged a plurality of connecting rods 22 along the radial direction of the lifting ring 21, and the driving arm of the swing cylinder 4 is fixedly connected to the intersection of the plurality of connecting rods 22.

[0041] Specifically in the present embodiment, the hook 25 is configured to be an S-shaped structure, with both ends of the hook 25 forming hook-shaped structures, one end of the hook 25 being hooked on the lifting ring 21 , and the other end being used to hook the dovetail connection sleeve 7 of the tower crane.

[0042] Furthermore, a plurality of grooves 23 are evenly arranged on the top of the lifting ring 21, and the hook 25 is hooked in the corresponding grooves 23 on the lifting ring 21 to prevent the hook 25 from sliding on the lifting ring 21 when the hanger 2 rotates. The hook 25 can stably hook the dovetail connecting sleeve of the tower crane.

[0043] In order to further increase the number of dovetail connection sleeves of the tower crane that can be accommodated in the rust removal box 1, a plurality of lifting rings 21 can be provided. Specifically, a plurality of lifting rings 21 are coaxially arranged up and down, and two adjacent lifting rings 21 are connected to each other via a connecting shaft 24. Specifically, both ends of the connecting shaft 24 are fixedly connected to the intersection of the connecting rod 22 inside the corresponding lifting ring 21, and the connection can be made by riveting, welding, bolt connection, etc.

[0044] As a specific embodiment, the liquid circulation device includes a water pump 51, the liquid inlet of the water pump 51 is connected to the bottom of the rust removal box 1 through a liquid inlet pipe 53, and the liquid discharge port of the water pump 51 is connected to one side of the rust removal box 1 through a liquid outlet pipe 52. Specifically, a base 11 is provided at the bottom of the rust removal box 1, and the base 11 is transitionally connected to the rust removal box 1 through a first connecting frame 12, and the water pump 51 is fixed to the base 11 by bolts; an interface 15 is provided on the box wall of one side of the rust removal box 1, and the interface 15 is located in the middle and upper position of the box wall of the rust removal box 1, and the liquid inlet pipe 53 is connected with the interface 15 in a cooperative manner. In this way, the rust remover inside the rust removal box 1 is drawn out from the bottom of the rust removal box 1 by the water pump 51, and re-enters the rust removal box 1 through the middle and upper position of the side wall of the rust removal box 1. The rust remover forms an internal circulation inside the box, so that an upward and downward circulation flow is formed between the rust remover and the hanger 2, further increasing the rust removal efficiency.

[0045] In this embodiment, the bottom of the rust removal box 1 is also connected to a drain pipe 16, which is equipped with a valve (not shown in the figure). The used rust remover is discharged through the drain pipe 16, and new rust remover is added to continue the descaling operation.

[0046] Further, a plurality of running wheels 6 are also provided below the rust removal box 1. Specifically, the running wheels 6 are universal wheels and are fixed to the bottom of the base 11 by bolts. The running wheels 6 facilitate the movement of the rust removal box 1.

[0047] It should be noted that the present embodiment also includes a hydraulic controller for controlling the hydraulic cylinder 3 and the swing cylinder 4, and a motor controller for controlling the water pump 51. The above structures all belong to the existing conventional technology, and their specific connection methods are not described in detail here.

[0048] Working principle: When in use, first add an appropriate amount of rust remover to the inside of the rust removal box 1 to ensure that the hanger 2 can be submerged and not in contact with the swing cylinder 4. Control the hydraulic cylinder 3 to retract, so that the hanger 2 moves out of the rust removal box 1, and then hang the hole hook of the tower crane dovetail connection sleeve 7 on the hook 25, and then control the hydraulic cylinder 3 to extend, move the hanger 2 to the inside of the rust removal box 1, so that the rust remover submerges most of the tower crane dovetail connection sleeve 7, and control the swing cylinder 4 to drive the hanger 2 to rotate back and forth, and the tower crane dovetail connection sleeve 2 rotates with the rotation of the hanger 2. The tower crane dovetail connection sleeve 7 during the rotation process increases the relative flow rate between the rust remover and the tower crane dovetail connection sleeve 7 in the horizontal direction, thereby improving the descaling efficiency.

[0049] The water pump 51 is controlled to lead the rust remover inside the rust removal box 1 out of the bottom of the rust removal box 1, and re-enter the rust removal box 1 through the middle and upper position of the side wall of the rust removal box 1. The rust remover forms an internal circulation inside the box, so that an up and down circulation flow is formed between the rust remover and the tower crane dovetail connecting sleeve 7, increasing the relative flow velocity between the rust remover and the tower crane dovetail connecting sleeve 7 in the vertical direction, and further increasing the rust removal efficiency.

[0050] After the descaling is completed, the swing cylinder 4 is controlled to stop working, and the dovetail connecting sleeve 7 of the tower crane after descaling is moved out of the rust removal box 1 by controlling the hydraulic cylinder 3 to contract, and then the dovetail connecting sleeve 7 of the tower crane can be removed.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
