Technical Field

[0001] The utility model relates to the technical field of material handling, in particular to a material handling device for a thermal power plant. Background Art

[0002] Material handling equipment refers to the equipment and tools used to transport, load, unload, and convey various materials in production, warehousing, logistics, and other fields. In thermal power plants, material handling equipment can quickly and efficiently move fuel from storage locations to boiler combustion areas, ensuring the continuity of the power generation process. The use of material handling equipment can reduce dependence on manpower and reduce labor costs.

[0003] The existing technology has the following problems:

[0004] In the storage system of a thermal power plant, there are many different types of fuel. Due to the flammability of fuel, in order to improve safety and improve the efficiency of material handling, the storage system of a thermal power plant can adopt intelligent storage.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0024] like Figure 1-5 As shown, the utility model provides a material handling device for a thermal power plant, including a driving guide vehicle 2. The driving guide vehicle 2 serves as the mobile basis of the entire device and is responsible for traveling along a predetermined route within the thermal power plant to transport materials to a designated location. The top of the driving guide vehicle 2 is fixedly connected to a material stacking base 3, which is used to carry the materials to be transported. The left side of the top of the driving guide vehicle 2 is fixedly connected to a material lifting device 1. The top of the material lifting device 1 penetrates the material stacking base 3 and extends to the outside of the top of the material stacking base 3. The material lifting device 1 lifts the material box placed on the material stacking base 3 and places it to a higher position.

[0025] like Figure 2 As shown, the utility model provides a technical solution for a material handling device in a thermal power plant: preferably, the material lifting device 1 includes two front and rear parallel support lifting plates 17, the bottom ends of the two support lifting plates 17 are fixedly connected to the left side of the top of the driving guide vehicle 2, and the two support lifting plates 17 are fixedly connected to the right side of the opposite sides with a lifting limit pipe 16, and a number of lifting components 18 are slidably connected between the two lifting limit pipes 16, and the two support lifting plates 17 are rotatably connected to the left side of the opposite sides with two upper and lower parallel lifting transmission components 14, and the outer surfaces of the two lifting transmission components 14 are rotatably connected to two lifting belts 15, and the rear end of the lower lifting transmission component 14 passes through the rear support lifting plate 17 and is fixedly connected to a transmission wheel 13, and a driving wheel 11 is provided on the right side of the transmission wheel 13, and the driving wheel 11 is provided on the inner side of the material stacking base 3, and a driving motor is provided at the front end of the driving wheel 11, and the transmission wheel 13 and the outer surface of the driving wheel 11 are rotatably connected with a transmission belt 12.

[0026] The driving motor starts, driving the driving wheel 11 to rotate. The driving wheel 11 drives the transmission wheel 13 to rotate through the transmission belt 12. The transmission wheel 13 drives the lower lifting transmission assembly 14 to rotate, and under the support of the two lifting transmission assemblies 14, it drives the lifting belt 15 to move. When the lifting belt 15 moves, it drives the lifting assembly 18 connected to it to slide between the lifting limit tubes 16. The moving direction of the lifting assembly 18 is determined by the movement direction of the lifting belt 15, and can realize the rising or falling action. Multiple lifting assemblies 18 can work at the same time, and can lift the material boxes stacked on the material stacking base 3 together. During the lifting process, the lifting limit tube 16 plays a role of limiting and guiding, ensuring that the lifting assembly 18 can stably perform the lifting and lowering movement.

[0027] like Figure 2 As shown, the utility model provides a technical solution for a material handling device in a thermal power plant: preferably, the lifting transmission assembly 14 includes a support column 142, and the front and rear ends of the support column 142 are respectively rotatably connected to the opposite sides of the two support lifting plates 17, and the front and rear sides of the outer surface of the support column 142 are fixedly connected to two transmission lifting wheels 141, and the outer surfaces of the two upper and lower parallel transmission lifting wheels 141 are jointly rotatably connected to the inner side of the nearest lifting belt 15, which is used to support and rotate the lifting belt 15.

[0028] like Figure 2-3 As shown, the utility model provides a technical solution for a material handling device in a thermal power plant: preferably, the lifting assembly 18 includes two front-to-rear parallel mobile lifting blocks 181, the right end of the mobile lifting block 181 is fixedly connected to a fixed block 182, and the bottom side of the right end of the fixed block 182 is fixedly connected to two front-to-rear parallel lifting hooks 183, and the outward corner of the bottom side of the right end of the lifting hook 183 is an inclined surface, and the opposite sides of the two mobile lifting blocks 181 are commonly fixedly connected with a number of upper and lower parallel synchronous connecting columns 184, and both ends of the synchronous connecting column 184 pass through the nearest mobile lifting block 181 and extend to the outside and are rotatably connected with a lifting pulley 185, and the outer surfaces of the upper and lower parallel lifting pulleys 185 on the same side are commonly slidably connected to the inner side of the nearest lifting limit tube 16, and the left end of the mobile lifting block 181 is fixedly connected to the outer surface of the nearest lifting belt 15.

[0029] When the lifting belt 15 moves, it will drive the movable lifting block 181 to move. The inclined surface of the lifting hook 183 can squeeze the sliding plate 35 to the right, so that the lifting hook 183 enters the corresponding position of the material box for hooking and fixing. The lifting pulley 185 is slidably connected to the lifting limit tube 16. The lifting limit tube 16 plays a role of limiting and guiding to ensure that the lifting assembly 18 remains stable during the lifting process.

[0030] like Figure 4As shown, the utility model provides a technical solution for a material handling device in a thermal power plant: preferably, the material stacking base 3 includes a support base 31, the bottom end of the support base 31 is fixedly connected to the top of the driving guide vehicle 2, a stacking trough 32 is opened in the middle of the top of the support base 31, a loading and unloading control component 33 is provided at the right end inside the stacking trough 32, a sliding plate 35 is slidably connected to the bottom of the stacking trough 32, and the left and right sides of the top of the sliding plate 35 are fixedly connected to the limiting edge 34.

[0031] like Figure 4-5 As shown, the utility model provides a technical solution for a material handling device in a thermal power plant: preferably, the bottom end of the sliding plate 35 is an inclined surface with the left side lower and the right side higher, and the right end of the right limiting edge 34 is fixedly connected to the left side of the loading and unloading control component 33.

[0032] The support base 31 provides stable support for the entire material stacking base 3. The stacking trough 32 is used to stack material boxes. The bottom end of the sliding plate 35 is a slope with the left side lower and the right side higher. When the lifting hook 183 is inserted under the material box, the slope of the lifting hook 183 will squeeze the material box, causing the material box to move to the right side of the stacking trough 32. Due to the slope of the sliding plate 35, the material box will be lifted, so that the lifting hook 183 can pass through the material box smoothly. The loading and unloading control component 33 can drive the sliding plate 35 to move by controlling the right limit edge 34 to realize loading and unloading control of the material box.

[0033] During unloading, after the bottom end of the material box contacts the sliding plate 35, the loading and unloading control component 33 can be used to control the sliding plate 35 to move to the right and rise. The material box moves synchronously under the limit of the limiting edge 34, so that the lifting hook 183 is separated from the material box and the material box is stacked on the top of the sliding plate 35. Subsequent material boxes can also be stacked upwards.

[0034] like Figure 5 As shown, the utility model provides a technical solution for a material handling device in a thermal power plant: preferably, the loading and unloading control component 33 includes a movable groove 331, which is opened at the right end of the inner side of the stacking trough 32, and a plurality of adaptive springs 333 are evenly fixedly connected to the right end of the inner side of the movable groove 331. A control gas rod 332 is arranged between every two adaptive springs 333, and the right end of the control gas rod 332 is fixedly connected to the right end of the inner side of the movable groove 331. The left end of the control gas rod 332 and the adaptive spring 333 are jointly fixedly connected to a pushing block 334. The outer surface of the pushing block 334 is slidably connected to the inner side of the movable groove 331, and the left end of the pushing block 334 extends to the inside of the stacking trough 32. A plurality of rising grooves 335 are evenly opened at the left end of the pushing block 334, and a lifting guide block 336 is slidably connected to the inner side of the rising groove 335. The left ends of the plurality of lifting guide blocks 336 are jointly fixedly connected to the right end of the right limiting rib 34.

[0035] The movable groove 331 provides installation space for other components of the loading and unloading control assembly 33. The adaptive spring 333 is compressed when the lifting hook 183 squeezes the material box to move the sliding plate 35. When the lifting hook 183 passes the material box, the elastic restoring force is used to push the pushing block 334 to move to the left, thereby driving the sliding plate 35 to reset. The control gas rod 332 can actively control the pushing block 334 to drive the sliding plate 35 to move to the right during unloading, so that the material box is separated from the lifting hook 183. The pushing block 334 slides in the movable groove 331 through the action of the adaptive spring 333 and the control gas rod 332, and the left end extends to the inside of the stacking trough 32 to push the sliding plate 35 to reset. The lifting guide block 336 is used to transmit the force of the pushing block 334, driving the sliding plate 35 to move and reset, and can slide at the left end of the pushing block 334 when the sliding plate 35 moves up to adapt to the height.

[0036] The following is a detailed description of the working principle of this material handling device for a thermal power plant.

[0037] like Figure 1-5 As shown, the material box is placed in the stacking trough 32 of the material stacking base, and the material box is stably stacked under the restriction of the limiting edge 34. The guide vehicle 2 is driven to travel along the predetermined route to move the device to the specified position. The drive motor is started to drive the drive wheel 11 to rotate, and the lifting belt 15 is moved through the transmission belt 12, the transmission wheel 13 and the lifting transmission assembly 14, thereby driving the lifting assembly 18 to rise and fall. The inclined surface of the lifting hook 183 squeezes the material box, so that the sliding plate 35 moves and lifts the material box. After the lifting hook 183 hooks the material box, it lifts it to a higher position. When unloading, the control gas rod 332 causes the push block 334 to drive the sliding plate 35 to move to the right and rise, and the material box is separated from the lifting hook 183 and placed on the top of the sliding plate 35.

[0038] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
