Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and more specifically, to a hoisting device for installing a reduction furnace. Background Technology

[0002] In the production of ultrafine tungsten carbide, the rotary tube reduction furnace is a key piece of equipment. As the tungsten industry develops towards higher precision and higher efficiency, the role of large rotary tube reduction furnaces in tungsten carbide powder production is becoming increasingly critical. Therefore, the installation quality directly affects the efficient performance of the reduction furnace, thus impacting the quality and production efficiency of tungsten products.

[0003] In the prior art, when a rotary tube reduction furnace needs to be hoisted and installed, the support for the rotary tube reduction furnace is set at an angle, and the rotary tube reduction furnace also needs to be installed at an angle on the support. Therefore, during hoisting and installation, the rotary tube reduction furnace is usually hoisted horizontally. When the horizontally hoisted rotary tube reduction furnace is placed on the angled support, it is usually difficult to align it, which affects the efficiency of the reduction furnace installation. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model proposes a hoisting device for installing a reduction furnace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for installing a reduction furnace, comprising a hoisting vehicle, tires rotatably connected to the bottom of the hoisting vehicle, a rotating platform fixedly connected to the top of the hoisting vehicle, a hoisting arm installed at the output end of the rotating platform, a winch fixedly connected to one side of the hoisting arm, a steel cable fixedly connected to the outer wall of the winch, the steel cable being wound around the outer wall of the winch, a pulley rotatably connected to the top of the hoisting arm, the steel cable being disposed on one side of the pulley, a hook fixedly connected to one end of the steel cable, a bracket fixedly connected to one side of the hoisting vehicle, a placement plate fixedly connected to the top of the bracket, a vertical plate fixedly connected to the top of the hoisting vehicle, a first hydraulic rod fixedly connected to one side of the vertical plate, a support plate fixedly connected to the output end of the first hydraulic rod, the support plate being disposed on one side of the placement plate, a ramp being provided at the top of the support plate, and the support plate being disposed at the bottom of the hook.

[0006] Furthermore, a side plate is fixedly connected to one side of the pallet, the side plate being L-shaped, and a second hydraulic rod is fixedly connected to one side of the side plate. A push plate is fixedly connected to the output end of the second hydraulic rod, and the push plate is located at the top of the pallet, the push plate being square in shape.

[0007] Furthermore, a first baffle is fixedly connected to one side of the tray, and a second baffle is fixedly connected to the other side of the tray.

[0008] Furthermore, the top of the pallet is provided with an installation groove, the inner wall of the installation groove is rotatably connected to a roller, and the outer wall of the roller is fixedly connected to a pulley. Multiple sets of installation grooves, rollers and pulleys are provided and are distributed in parallel at the top of the pallet.

[0009] Furthermore, a sliding frame is fixedly connected to the top of one side of the hoisting vehicle, and a slider is fixedly connected to the bottom of the pallet.

[0010] Furthermore, a pad is fixed to one side of the first baffle. The pad is made of rubber, and two sets of the pad are provided. The other set of the pad is fixed to one side of the second baffle.

[0011] The technical effects and advantages of the hoisting equipment for installing a reduction furnace according to this utility model are as follows:

[0012] With the cooperation of the winch and the hoisting arm, the reduction furnace can be hoisted onto the pallet. By activating the first hydraulic rod, the pallet can be moved to one side. As the pallet moves, it will also move the reduction furnace above it to one side until the pallet touches one side of the placement plate. This allows the reduction furnace to be moved to one side of the placement plate and keeps the reduction furnace tilted and aligned with the tilted placement plate. By activating the second hydraulic rod, the push plate can be moved to one side. As the push plate moves, it can push the reduction furnace to move, thus facilitating the movement of the reduction furnace from the pallet to the placement plate. This solves the problem that rotary tube reduction furnaces are not convenient to install on tilted supports during hoisting. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Reference Figure 1-5 A hoisting device for installing a reduction furnace includes a hoisting vehicle 1. Tires 2 are rotatably connected to the bottom of the hoisting vehicle 1. A rotating platform 3 is fixed to the top of the hoisting vehicle 1. A hoisting arm 4 is installed at the output end of the rotating platform 3. A winch 5 is fixed to one side of the hoisting arm 4. A steel cable 6 is fixed to the outer wall of the winch 5 and wound around the outer wall of the winch 5. A pulley is rotatably connected to the top of the hoisting arm 4. The steel cable 6 is located on one side of the pulley and a hook 7 is fixed to one end of the steel cable 6. A bracket 8 is fixed to one side of the hoisting vehicle 1. A placement plate 9 is fixed to the top of the bracket 8. A vertical plate 10 is fixed to the top of the hoisting vehicle 1. A first hydraulic rod 11 is fixed to one side of the vertical plate 10. A support plate 12 is fixed to the output end of the first hydraulic rod 11 and is located on one side of the placement plate 9. A ramp is provided at the top of the support plate 12, and the support plate 12 is located at the bottom of the hook 7.

[0023] To address the issue of the rotary tube reduction furnace being inconvenient to install on the inclined support 8 during hoisting, when hoisting the furnace, a hoisting rope can be installed on the outside of the furnace first. This rope is then attached to the hook 7, and the hoisting cable 6 is wound up by the winch 5 to lift the hook 7 and the furnace upwards. The position of the furnace is then adjusted using the coordination of the rotary table 3 and the hoisting arm 4, and finally, the furnace is hoisted onto the pallet 12. The hoisting vehicle 1 is then moved to one side of the placement plate 9 by the drive tires 2, and then the hoisting can begin... The first hydraulic rod 11 can push the pallet 12 to one side. When the pallet 12 moves, it will drive the reduction furnace above to move to one side until the pallet 12 abuts against one side of the placement plate 9. This allows the position of the reduction furnace to be moved to one side of the placement plate 9 and keeps the reduction furnace tilted and aligned with the tilted placement plate 9. Then, the lifting arm 4 is used to adjust the lifting position of the reduction furnace until the tilted reduction furnace is lifted onto the tilted placement plate 9, which makes it easy to tilt the reduction furnace onto the placement plate 9.

[0024] Reference Figure 4 A side plate 13 is fixedly connected to one side of the pallet 12. The side plate 13 is L-shaped. A second hydraulic rod 14 is fixedly connected to one side of the side plate 13. A push plate 15 is fixedly connected to the output end of the second hydraulic rod 14. The push plate 15 is located at the top of the pallet 12 and is square in shape.

[0025] By providing a side plate 13 on one side of the pallet 12, it is easy to install the second hydraulic rod 14 in a designated position. When it is necessary to move the reduction furnace on the pallet 12 to the placement plate 9, the push plate 15 can be pushed to one side by activating the second hydraulic rod 14. When the push plate 15 moves, the reduction furnace can be pushed to move, thereby facilitating the movement of the reduction furnace from the pallet 12 to the placement plate 9.

[0026] Reference Figure 5 A first baffle 16 is fixedly connected to one side of the pallet 12, and a second baffle 17 is fixedly connected to the other side of the pallet 12.

[0027] By providing a first baffle 16 and a second baffle 17 on both sides of the pallet 12, when the reduction furnace is placed on the pallet 12, the top and bottom positions of the reduction furnace can be easily fixed by the first baffle 16 and the second baffle 17 provided on the pallet 12, preventing the tilted reduction furnace from sliding down.

[0028] Reference Figure 4 The top of the pallet 12 is provided with an installation groove, the inner wall of the installation groove is rotatably connected to a roller 18, and the outer wall of the roller 18 is fixedly connected to a pulley. Multiple sets of installation grooves, rollers 18 and pulleys are provided and are distributed in parallel at the top of the pallet 12.

[0029] By providing an installation groove at the top of the pallet 12, the roller 18 and pulley can be installed inside the installation groove. When the reduction furnace is moved from the pallet 12 to the placement plate 9, the roller 18 and pulley can be used to improve the smoothness of the movement of the reduction furnace, making it easier for the reduction furnace to be moved onto the placement plate 9.

[0030] Reference Figure 5 A sliding frame 19 is fixedly connected to the top of one side of the hoisting vehicle 1, and a slider 20 is fixedly connected to the bottom of the pallet 12. The slider 20 is slidably connected to the inner wall of the sliding frame 19. Two sets of sliding frames 19 and sliders 20 are provided and are distributed in parallel at the bottom of the pallet 12.

[0031] By setting a sliding frame 19 on the crane vehicle 1, when the first hydraulic rod 11 pushes the pallet 12 to move to one side, the slider 20 at the bottom of the pallet 12 will slide in the sliding frame 19. Thus, the sliding frame 19 and the slider 20 can limit the movement trajectory of the pallet 12 and prevent the pallet 12 from deviating during movement.

[0032] Reference Figure 5 A pad 21 is fixedly connected to one side of the first baffle 16. The pad 21 is made of rubber. Two sets of pads 21 are provided. The other set of pads 21 is fixedly connected to one side of the second baffle 17.

[0033] By providing gaskets on one side of the first baffle 16 and the second baffle 17, when the reduction furnace is hoisted onto the support plate 12, the rubber gaskets can be used to protect the contact surfaces between the reduction furnace and the first baffle 16 and the second baffle 17, preventing damage to the contact surfaces between the first baffle 16 and the second baffle 17 and the reduction furnace.

[0034] Working Principle: To address the issue of the rotary tube reduction furnace being inconvenient to install on the inclined support 8 during hoisting, when hoisting the rotary tube reduction furnace, a hoisting rope can be first installed on the outside of the furnace. This rope is then hooked onto the hook 7. The winch 5 then winds up the steel cable 6 to lift the hook 7 and the reduction furnace upwards. The position of the reduction furnace is then adjusted using the coordination of the rotary table 3 and the hoisting arm 4. Finally, the reduction furnace is hoisted onto the support plate 12. The first baffle 16 and the second baffle 17 on the support plate 12 are used to secure the top of the reduction furnace. The bottom position is fixed to prevent the tilted reduction furnace from sliding down. Rubber gaskets protect the contact surfaces between the reduction furnace and the first baffle 16 and the second baffle 17, preventing damage to these surfaces. The crane 1 is moved to one side of the placement plate 9 by driving the tires 2. Then, the first hydraulic rod 11 is activated, pushing the pallet 12 to one side. As the pallet 12 moves, it pulls the reduction furnace above it to one side as well. When the pallet 12 rests against one side of the placement plate 9, the position of the reduction furnace can be moved to one side of the placement plate 9, and the reduction furnace is kept tilted and aligned with the tilted placement plate 9. When the first hydraulic rod 11 pushes the pallet 12 to one side, the slider 20 at the bottom of the pallet 12 will slide within the sliding frame 19. Thus, the slider 20 and the sliding frame 19 can limit the movement trajectory of the pallet 12 and prevent the pallet 12 from deviating during movement. When it is necessary to move the reduction furnace on the pallet 12 onto the placement plate 9, the second hydraulic rod can be activated. 14 pushes the push plate 15 to one side. When the push plate 15 moves, it can push the reduction furnace to move, which facilitates the reduction furnace to move from the pallet 12 to the placement plate 9. When the reduction furnace is moved from the pallet 12 to the placement plate 9, the smoothness of the movement of the reduction furnace can be improved by the roller 18 and pulley, so that the reduction furnace can be moved to the placement plate 9. Then, the lifting arm 4 is used to adjust the lifting position of the reduction furnace until the inclined reduction furnace is lifted to the inclined placement plate 9, which makes it easy to install the reduction furnace at an incline on the placement plate 9.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
