Description

Technical Field

[0001] This utility model belongs to the technical field of MVR evaporation systems, and particularly relates to an electric rocker arm type hook device for the maintenance of MVR evaporation systems. Background Technology

[0002] Mechanical Vapor Recompression (MVR) evaporation systems are a highly efficient and energy-saving evaporation technology primarily used for treating saline wastewater and other processes requiring evaporation and concentration. The core principle of an MVR system is to utilize a high-efficiency steam compressor to compress the secondary steam generated during the evaporation process, increasing its pressure and temperature. This secondary steam is then used as a heat source to re-enter the evaporator for reheating, thus achieving the recycling of thermal energy. Therefore, due to its high efficiency and energy-saving characteristics, MVR evaporation systems are widely used in various fields such as chemical, pharmaceutical, and food industries.

[0003] However, during the routine maintenance and repair of MVR evaporation systems, due to the generally large size and weight of these systems, and the fact that their components are at high temperatures during operation, it is difficult for maintenance personnel to remove the components that need maintenance. Furthermore, there are significant safety hazards involved in removing these components. Utility Model Content

[0004] The purpose of this invention is to provide an electric rocker arm type hook device for the maintenance of MVR evaporation systems, so as to improve the convenience and safety of maintenance personnel when removing components to be maintained from the MVR evaporation system.

[0005] The solution adopted by this utility model is as follows: This utility model includes a fixed base, on which a supporting column is installed. The top of the supporting column is provided with an upwardly inclined arm located above the MVR evaporation system. The outer end of the inclined arm is suspended with a hook that can be raised and lowered. The hook is used to hook and hang components from above the MVR evaporation system.

[0006] Furthermore, the present invention also includes an auxiliary seat, which is located next to the fixed base. The auxiliary seat is provided with an upwardly inclined auxiliary force-bearing beam, which is located below the inclined arm. The top end of the auxiliary force-bearing beam is connected to the top end of the supporting column.

[0007] Furthermore, the present invention also includes a transverse main guide rail and a transverse auxiliary guide rail. The fixed base is equipped with a transverse guide block that slides on the transverse main guide rail, and the auxiliary base is equipped with an auxiliary slider that slides on the transverse auxiliary guide rail.

[0008] Furthermore, both the transverse main guide rail and the transverse auxiliary guide rail are T-shaped guide rails, and both the transverse guide block and the auxiliary slider are provided with sliders adapted to the top shape of the T-shaped guide rail.

[0009] Furthermore, this utility model also includes a transverse drive motor, which drives a transverse chain. A drive plate is connected between the transverse guide block and the auxiliary slider, and a certain part of the transverse chain is fixedly connected to the middle of the drive plate.

[0010] Furthermore, the lateral drive motor is connected to the lateral chain via a lateral variable gearbox.

[0011] Furthermore, the hook is equipped with a weight sensor, and the transverse variable gearbox is equipped with a clutch for switching gears with different transmission ratios. The clutch is electrically connected to the weight sensor.

[0012] The beneficial effects of this utility model are:

[0013] When maintenance personnel need to remove a component from the MVR evaporation system, they can move the fixed base or fix the fixed base next to the component to be removed inside the MVR evaporation system, so that the hook is located above the component to be removed. At this time, by controlling the lifting and lowering of the hook, maintenance personnel can move away from dangerous positions such as the MVR evaporation system, the component to be removed, or high-temperature components inside the MVR evaporation system, and can also remove the component to be removed from the MVR evaporation system, thereby improving the safety and convenience of maintaining the MVR evaporation system.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, in an embodiment, the present invention includes a fixed base 1, on which a support column 11 is installed. The top of the support column 11 is provided with an upwardly inclined arm 12 located above the MVR evaporation system 7. The outer end of the inclined arm 12 is suspended by a hook 13 that can be lifted and moved. The hook 13 is used to lift and place the component to be maintained from above the MVR evaporation system 7.

[0021] When maintenance personnel need to remove a component from the MVR evaporation system 7, they can move the fixed base 1 or fix the fixed base 1 next to the component to be removed inside the MVR evaporation system 7, so that the hook 13 is located above the component to be removed. At this time, by controlling the lifting and lowering of the hook 13, maintenance personnel can move away from dangerous locations such as the MVR evaporation system 7, the component to be removed, or high-temperature components inside the MVR evaporation system 7, and can also remove the component to be removed from the MVR evaporation system 7, thereby improving the safety and convenience of maintaining the MVR evaporation system 7.

[0022] Furthermore, a winding motor is installed on the fixed base 1, which drives a winding reel. The winding motor winds up the winding reel, which contains a steel rope. A hanging ring is provided at the outer end of the inclined arm 12, and the outermost end of the steel rope passes through the hanging ring and is connected to the hook 13, so that the hook 13 suspends the outer end of the inclined arm 12. During operation, the winding motor can drive the winding reel to wind up or release the steel rope, thereby controlling the lifting and lowering of the hook 13.

[0023] Alternatively, the lifting and lowering of the drive hook 13 can be achieved using a conventional crane structure to lift and lower the component to be maintained from above the MVR evaporation system 7.

[0024] In this embodiment, the present invention further includes an auxiliary seat 2, which is located next to the fixed base 1. The auxiliary seat 2 is provided with an upwardly inclined auxiliary force-bearing beam 21, which is located below the inclined arm 12. The top end of the auxiliary force-bearing beam 21 is connected to the top end of the supporting column 11. When the hook 13 lifts the component to be maintained, the auxiliary force-bearing beam 21 can effectively share the weight borne by the inclined arm 12, thereby improving the stability and strength of the inclined arm 12.

[0025] In this embodiment, the present invention further includes a transverse main guide rail 3 and a transverse auxiliary guide rail 4. The fixed base 1 is equipped with a transverse guide block 31 that slides on the transverse main guide rail 3, and the auxiliary base 2 is equipped with an auxiliary slider 41 that slides on the transverse auxiliary guide rail 4. This allows the fixed base 1 and the auxiliary base 2 to move laterally, enabling the hook 13 to move to different positions above the MVR evaporation system 7, thereby allowing the hook 13 to lift components at different positions.

[0026] In this embodiment, both the transverse main guide rail 3 and the transverse auxiliary guide rail 4 are T-shaped guide rails, and both the transverse guide block 31 and the auxiliary slider 41 are equipped with sliders adapted to the top shape of the T-shaped guide rails. This ensures that when the hook 13 lifts the component to be maintained, the force borne by the fixed base 1 and the auxiliary seat 2 can be stably applied to the transverse main guide rail 3 and the transverse auxiliary guide rail 4. Furthermore, when the fixed base 1 applies a tensile force to the transverse main guide rail, the auxiliary seat 2 can simultaneously apply a downward pressure to the transverse auxiliary guide rail 4, thereby making the inclined arm 12 more stably stressed.

[0027] In this embodiment, the present invention further includes a transverse drive motor 5, which drives a transverse chain 51. A drive plate 52 is connected between the transverse guide block 31 and the auxiliary slider 41, and a certain part of the transverse chain 51 is fixedly connected to the middle of the drive plate 52. Therefore, the transverse drive motor 5 can drive the transverse chain 51 to move the drive plate 52. At this time, the drive plate 52 can synchronously drive the fixed base 1 and the auxiliary seat 2 to move through the transverse guide block 31 and the auxiliary slider 41, thereby adjusting the position of the hook 13.

[0028] In this embodiment, the lateral drive motor 5 is connected to the lateral chain 51 via a lateral variable gearbox 6. This allows the hook 13 to lift relatively heavy, relatively light, or unlifted objects by engaging gears with different transmission ratios, thereby increasing the speed of the hook 13's movement and enabling more efficient use of the power output from the lateral drive motor 5.

[0029] In this embodiment, the hook 13 is equipped with a weight sensor, and the transverse variable gearbox 6 is equipped with a clutch for switching gears with different transmission ratios. The clutch is electrically connected to the weight sensor. The weight sensor senses the weight of the item currently being lifted by the hook 13 and sends gravity information to the clutch, enabling the clutch to control the engagement of the gear with the corresponding transmission ratio based on this gravity information, thereby improving the stability and efficiency of the hook 13 during movement.
