Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of catalyst module installation, specifically relating to a mobile trolley device for placing reactor catalyst modules. Background Technology
[0002] Denitrification reactors are crucial equipment for reducing nitrogen oxide emissions. Inside the reactor, a certain number of catalyst modules must be placed according to the design to ensure sufficient reaction between the boiler flue gas and injected ammonia, thereby reducing NOx concentration to meet environmental standards.
[0003] The catalyst module needs to be placed at the inlet of the denitrification reactor using a transport device, which is usually a trolley that is pushed by manpower or driven by an electric motor.
[0004] If the trolley is subjected to external forces while transporting the catalyst module, such as uneven ground or improper operation, the rollers at the bottom of the trolley will not remain level, causing the trolley's center of gravity to shift. When the center of gravity shifts to a certain extent, the trolley will lose balance and tip over. A tip-over will damage the catalyst module, requiring replacement and increasing replacement costs. Utility Model Content
[0005] This utility model provides a mobile trolley device for placing reactor catalyst modules, aiming to solve the technical problem that the trolley is prone to tipping over due to external forces, increasing the cost of replacing catalyst modules.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a mobile trolley device for placing a reactor catalyst module, comprising:
[0007] A steel frame platform that extends in the front-to-back direction and is fixed to the ground;
[0008] Two guide rails are distributed parallel to each other on both sides of the steel frame platform in the left-right direction. The guide rails extend along the length of the steel frame platform. The two guide rails are respectively located on the left and right sides of the steel frame platform. Each guide rail includes a base fixed to the steel frame platform and a limiting post fixed to the top of the base.
[0009] A frame is disposed above the steel frame platform. Slides are fixed to both the left and right sides of the bottom of the frame. Each slide has a groove that slides to fit the limiting post, and the opening of the groove is smaller than the maximum width of the limiting post in the left-right direction.
[0010] A power unit, connected to the vehicle frame, is used to drive the vehicle frame to move along the steel frame platform.
[0011] In one possible implementation, the power unit includes:
[0012] A roller is rotatably connected to the vehicle frame, and the roller rotates about a left-right axis.
[0013] A traction rope is wound around the outer circumference of the drum, and its two ends are respectively fixed to the front and rear ends of the steel frame platform; and
[0014] The first driving component is connected to the roller drive.
[0015] In one possible implementation, the frame is slidably connected to a compensating rod in the front-rear direction, one end of the compensating rod is rotatably connected to a compensating shaft, the compensating shaft is drively connected to the first driving member, and a buffer member is fixed between the compensating shaft and the frame, the buffer member extending and retracting in the front-rear direction.
[0016] In one possible implementation, a placement platform is fixedly connected to the top of the vehicle frame. Through slots are provided at both the front and rear ends of the top surface of the placement platform. A lifting plate is provided in the through slots. A first telescopic member is provided below the lifting plate. The first telescopic member is fixedly connected to the vehicle frame and extends and retracts in the vertical direction.
[0017] In one possible implementation, guide posts are fixed at both ends of the bottom wall of the lifting plate, and the guide posts are slidably connected to the vehicle frame in the vertical direction.
[0018] In one possible implementation, the lifting plate has two storage slots along the left-right direction, and a limiting seat is rotatably connected in the storage slot.

A second telescopic member is fixed between the limiting plate and the limiting seat, and the second telescopic member extends and retracts in the left-right direction.
[0020] In one possible implementation, an angle sensor is installed on the limiting seat to monitor the rotation angle of the limiting seat, and the first telescopic member, the second driving member, the second telescopic member, and the angle sensor are respectively communicatively connected to the controller.
[0021] In one possible implementation, a pressure sensor is mounted on the limiting plate to monitor the pressure value borne by the limiting plate, and the pressure sensor is communicatively connected to the second telescopic member.
[0022] In one possible implementation, the steel frame platform is fixed to limit stops at both the front and rear ends, and the limit stops have a telescopic range in the front-rear direction.

[0040] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0041] Please refer to the following: Figures 1 to 7 This invention describes a mobile trolley device for placing reactor catalyst modules. The mobile trolley device for placing reactor catalyst modules includes a steel frame platform 10, guide rails 20, a frame 30, and a power unit 40. The steel frame platform 10 extends in the front-to-back direction and is fixed to the ground. Two guide rails 20 are parallel to each other on both sides of the steel frame platform 10 in the left-to-right direction, extending along the length of the steel frame platform 10. Each guide rail 20 includes a base 201 fixed to the steel frame platform 10 and a limiting post 202 fixed to the top of the base 201. The frame 30 is positioned above the steel frame platform 10. Slide seats 301 are fixed to the left and right sides of the bottom of the frame 30. Each slide seat 301 has a sliding groove 3011 that slides and adapts to the limiting post 202. The opening of the sliding groove 3011 is smaller than the maximum width of the limiting post 202 in the horizontal direction. The power unit 40 is connected to the frame 30 and is used to drive the frame 30 to move along the steel frame platform 10.
[0042] The mobile trolley device for placing the reactor catalyst module provided in this embodiment, compared with the prior art, uses a power unit 40 to drive the frame 30 to move along the steel frame platform 10, preventing the frame 30 from tipping over due to uneven ground. When the frame 30 is affected by other external forces, the slide 301 of the frame 30 always slides along the limiting seat 80 during movement, and the slide 301 cannot disengage from the limiting post 202, so that the frame 30 will not tip over when affected by external forces. In summary, this application reduces the probability of the frame 30 tipping over, thereby reducing the probability of the catalyst module being damaged due to tipping over, and thus reducing replacement costs.
[0043] In some embodiments, see Figure 3 and Figure 4 The power unit 40 includes a roller 401, a traction rope 402, and a first drive unit 403. The roller 401 is rotatably connected to the frame 30 and rotates around the left and right direction as the axis of rotation. The traction rope 402 is wound around the outer circumference of the roller 401, and the two ends of the traction rope 402 are fixedly connected to the front and rear ends of the steel frame platform 10, respectively. The first drive unit 403 is connected to the roller 401 for transmission.
[0044] Specifically, the first driving component 403 is a motor, and a reducer 50 is installed between the first driving component 403 and the roller 401.
[0045] Specifically, the front and rear ends of the steel frame platform 10 are both fixed with base plates 101, and traction buckles 1011 are fixedly connected to the base plates 101. One end of the traction rope 402 is fixedly connected to one of the traction buckles 1011, and the other end of the traction rope 402 is fixedly connected to the other traction buckle 1011.
[0046] The first drive unit 403 starts and drives the drum 401 to rotate. The drum 401 winds up the traction rope 402 on one side and releases the traction rope 402 on the other side. This causes the side of the frame 30 where the traction rope 402 is wound to move. The direction of movement of the frame 30 can be changed by changing the direction of the first drive unit 403.
[0047] In some embodiments, see Figure 5 The frame 30 is slidably connected to a compensating rod 302 in the front-rear direction. One end of the compensating rod 302 is rotatably connected to a compensating shaft 3021. The compensating shaft 3021 is connected to the first driving member 403 in a transmission connection. A buffer member 303 is fixed between the compensating shaft 3021 and the frame 30. The buffer member 303 extends and retracts in the front-rear direction.
[0048] Specifically, a connecting frame 3022 is fixedly provided at one end of the compensating rod 302. The connecting frame 3022 is U-shaped, and the compensating shaft 3021 is rotatably connected to the inner wall of the connecting frame 3022. The compensating shaft 3021 is connected to the reducer 50 by belt drive.
[0049] It should be noted that the buffer 303 is a spring.
[0050] The first drive unit 403 starts and drives the reducer 50 to move. The reducer 50 causes the compensation shaft 3021 to rotate through the belt drive. The output shaft of the first drive unit 403 will wobble during the rotation. This wobble will be transmitted to the compensation shaft 3021. The wobble of the compensation shaft 3021 will cause the buffer 303 to deform and generate a reverse force to counteract the external force, thereby resisting the wobble and keeping the frame 30 stable.
[0051] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The top of the frame 30 is fixedly connected to a placement platform 60. Both the front and rear ends of the top surface of the placement platform 60 are provided with through grooves 601. A lifting plate 602 is provided in the through grooves 601. A first telescopic member 304 is provided below the lifting plate 602. The first telescopic member 304 is fixedly connected to the frame 30 and can extend and retract in the vertical direction.
[0052] When the chassis 30 moves to the preset position, the first telescopic member 304 extends to raise the lifting plate 602, thereby raising the catalyst module located on the lifting plate 602. This creates a gap between the catalyst module and the top surface of the placement platform 60, which facilitates the transfer of the catalyst module.
[0053] In some embodiments, see Figure 5 Guide posts 70 are fixed at both ends of the bottom wall of the lifting plate 602, and the guide posts 70 are slidably connected to the frame 30 in the vertical direction.
[0054] The guide column 70 guides the lifting plate 602 to move along a predetermined vertical direction, preventing the lifting plate 602 from shifting or swaying during the movement.
[0055] In some embodiments, see Figure 6 and Figure 7 The lifting plate 602 has two storage slots 6021 along the left and right directions. A limit seat 80 is rotatably connected in the storage slot 6021. The rotation axis of the limit seat 80 is parallel to the left and right directions. A second driving member 6022 is installed in the storage slot 6021. The second driving member 6022 is connected to the limit seat 80 in a transmission manner.
[0056] Specifically, the limiting seat 80 is also connected to the limiting plate 801. The limiting plate 801 is located on the side where the two limiting seats 80 are close to each other. A second telescopic member 802 is fixed between the limiting plate 801 and the limiting seat 80. The second telescopic member 802 extends and retracts in the left and right direction.
[0057] Specifically, an angle sensor is installed on the limit seat 80. The angle sensor is used to monitor the rotation angle of the limit seat 80. The first telescopic member 304, the second driving member 6022, the second telescopic member 802, and the angle sensor are respectively connected to the controller for communication.
[0058] It should be noted that the second driving component 6022 is a motor, and the first telescopic component 304 and the second telescopic component 802 can be a hydraulic cylinder, a telescopic oil cylinder, or an electric cylinder.
[0059] The first telescopic component 304 extends, causing the lifting plate 602 to move upward. Simultaneously, the second driving component 6022 rotates clockwise, causing the limiting seat 80 to rotate from a horizontal to a vertical position. Then, the second telescopic component 802 moves the limiting plate 801 towards the catalyst module until the limiting plate 801 is pressed against the catalyst module. At this point, the second telescopic component 802 remains extended. During the transfer of the catalyst module, the second telescopic component 802 retracts. Once fully retracted, the second driving component 6022 rotates counterclockwise, causing the limiting seat 80 to rotate from a vertical to a horizontal position. Simultaneously, the first telescopic component 304 moves the lifting plate 602 downward.
[0060] In some embodiments, a pressure sensor is installed on the limiting plate 801. The pressure sensor is used to monitor the pressure value borne by the limiting plate 801 and is communicatively connected to the second telescopic member 802.
[0061] The pressure value borne by the limiting plate 801 represents the degree of tightness of the limiting plate 801 against the catalyst module. By setting a second preset value, the degree of tightness of the limiting plate 801 against the catalyst module can both clamp the catalyst module tightly and prevent damage to the catalyst module.
[0062] In some embodiments, see Figure 4 The steel frame platform 10 has limit stops 1012 fixed at both the front and rear ends, and the limit stops 1012 have a telescopic range in the front and rear directions.
[0063] When the frame 30 comes into contact with the limit stop 1012, the limit stop 1012 has a certain amount of extension and retraction, which buffers the frame 30 and protects the frame 30.
[0064] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
