Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to positioning conveying equipment and a method for installing thermal power generation facilities. Background Art

[0002] In the thermal power generation industry, the installation of thermal power generation facilities is an important link. In the installation process of thermal power generation facilities, the transportation of thermal power generation facilities is a crucial link. Traditionally, these facilities are often transported by manual labor or simple mechanical equipment, which is not only inefficient but also has many safety hazards.

[0003] For example, although some conveying equipment can realize basic conveying functions, they have problems with poor stability and poor positioning accuracy during transportation. During transportation, debris attached to the surface of the track will cause the conveying equipment to bump, resulting in poor stability; when the conveying equipment stops running, it will still cause the transported equipment to move, resulting in poor positioning accuracy. Summary of the invention

[0004] The purpose of the present invention is to provide a positioning conveying device and method for the installation of thermal power generation facilities, which is used to solve the technical problems in the prior art that during the transportation of the conveying equipment, the debris attached to the surface of the track will cause the conveying equipment to shake, resulting in poor stability; when the conveying equipment stops running, it will still cause the transported equipment to move, resulting in poor positioning accuracy.

[0008] Preferably, the positioning assembly includes: two movable plates, both of which are slidably connected to the bottom surface of the supporting frame; two tooth plates, respectively installed on the opposite sides of the two movable plates and matching the fixed rack; a plurality of springs, whose two ends are respectively fixedly connected to the two movable plates; a second motor, installed on the bottom surface of the supporting frame; and a cam, installed on the power output shaft of the second motor and in contact with the two movable plates.

[0009] Preferably, the cleaning assembly includes: a mounting plate mounted on the bottom surface of the carrier frame; a reciprocating screw rotatably mounted on the mounting plate; a movable seat sleeved on the reciprocating screw; a cleaning brush fixedly sleeved on the movable seat and in contact with the track; and a guide plate mounted on the mounting plate, passing through the cleaning brush and being slidably connected to the cleaning brush.

[0010] Preferably, the cleaning assembly further comprises: a driven gear mounted on an end of the reciprocating screw away from the mounting plate; and a driving gear mounted on the moving wheel and meshingly connected with the driven gear.

[0011] Preferably, the positioning and conveying mechanism further includes a limiting assembly, which includes: four hydraulic cylinders respectively mounted on the inner walls of the supporting frame; and two clamping plates fixedly connected to the extending ends of the two hydraulic cylinders.

[0012] Preferably, the positioning and conveying equipment for installing the thermal power generation facility also includes a control system, which includes: a data acquisition module, which is used to collect comprehensive data information of the positioning and conveying equipment, wherein the comprehensive data information includes weight data of the thermal power generation facility, volume data of the thermal power generation facility and track flatness data; a data analysis module, which generates a stability influence coefficient based on the comprehensive data information, and generates a corresponding driving speed level based on the stability influence coefficient; a data acquisition module, which is used to collect a historical training data set of the positioning and conveying equipment, and the historical training data set includes comprehensive influence data of driving speed and acceleration and deceleration of the load frame; wherein the comprehensive influence data of driving speed includes comprehensive data information and driving speed data of the load frame; an acceleration and deceleration prediction module, which trains a machine learning model for predicting the acceleration and deceleration of the load frame based on the historical training data set, collects the comprehensive influence data of driving speed in real time, and inputs it into the trained machine learning model to predict the acceleration and deceleration of the load frame.

[0013] Preferably, the stability influence coefficient is generated as follows: Wherein, Wd is the stability influence coefficient, Zl is the weight data of the thermal power generation facility on the carrier, Tj is the volume data of the thermal power generation facility on the carrier, and Pz is the track flatness data.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Figure 1-Figure 4 As shown, the positioning and conveying equipment for installing thermal power generation facilities includes two rails 100 , two fixed racks 101 and a positioning and conveying mechanism 200 .

[0032] The two rails 100 are both installed on the ground, the two fixed racks 101 are both installed on the ground, and the two fixed racks 101 are located between the two rails 100 , and teeth are arranged on opposite sides of the two fixed racks 101 .

[0033] The positioning and conveying mechanism 200 is installed on two rails 100 , and the positioning and conveying mechanism 200 includes a carrier frame 201 , a conveying assembly 220 , four groups of cleaning assemblies 230 and a positioning assembly 240 .

[0034] The carrier frame 201 is located directly above the two rails 100; the conveying assembly 220 is installed on the bottom surface of the carrier frame 201, and the conveying assembly 220 is in contact with the two rails 100; four groups of cleaning assemblies 230 are all installed on the bottom surface of the carrier frame 201, and the cleaning assembly 230 is used to contact the rails 100; the positioning assembly 240 is installed on the bottom surface of the carrier frame 201, and the positioning assembly 240 is matched with the fixed rack 101. When the positioning assembly 240 is engaged with the fixed rack 101, the movement of the carrier frame 201 along the rails 100 is restricted.

[0035] Specifically, the thermal power generation facilities to be transported are placed on the carrier 201, and the conveying component 220 is started to drive the carrier 201 to move along the two tracks 100. When the carrier 201 moves, the cleaning component 230 will clean the upper surface of the track 100 and remove the debris attached to the upper surface of the track 100 to prevent the debris from affecting the smooth movement of the carrier 201, thereby improving the stability of the carrier 201.

[0036] When the support frame 201 and the thermal power generation facility it supports reach the designated position, the positioning assembly 240 is activated to engage with the two fixed racks 101, so that the conveying assembly 220 cannot move, thereby fixing the support frame 201 on the track 100.

[0037] like Figure 4 As shown, the conveying assembly 220 includes two shafts 221, four moving wheels 222 and a motor reducer 223. The two shafts 221 are rotatably mounted on the bottom surface of the carrier 201; the four moving wheels 222 are respectively mounted at both ends of the two shafts 221, and the four moving wheels 222 are respectively connected to the two tracks 100; the motor reducer 223 is mounted on the bottom surface of the carrier 201, and the motor reducer 223 is connected to any shaft 221.

[0038] Specifically, when the motor reducer 223 is running, it will drive a shaft 221 to rotate, and then drive two moving wheels 222 to rotate, and then drive the carrier 201 to move along the two tracks 100. When the carrier 201 moves, it will drive the other two moving wheels 222 to rotate.

[0039] like Figure 2 , Figure 4 and Figure 6 As shown, the positioning assembly 240 includes two movable plates 241, two tooth plates 242, a plurality of springs 243, a second motor 244 and a cam 245. The two movable plates 241 are slidably connected to the bottom surface of the carrier 201; the two tooth plates 242 are respectively installed on the opposite sides of the two movable plates 241, and the two tooth plates 242 match the fixed rack 101; the two ends of the plurality of springs 243 are respectively fixedly connected to the two movable plates 241; the second motor 244 is installed on the bottom surface of the carrier 201; the cam 245 is installed on the power output shaft of the second motor 244, and the cam 245 contacts the two movable plates 241.

[0040] Specifically, when the second motor 244 is running, the power output shaft of the second motor 244 will drive the cam 245 to rotate, and the rotating cam 245 will move the two movable plates 241 in opposite directions, thereby causing the two tooth plates 242 to engage with the two fixed racks 101 respectively, thereby preventing the moving wheel 222 from moving along the track 100, thereby fixing the carrier 201 on the track 100.

[0041] like Figure 4 and Figure 5 As shown, the cleaning assembly 230 includes a mounting plate 231 , a reciprocating screw 232 , a moving seat 233 , a cleaning brush 234 , a guide plate 235 , a driven gear 236 and a driving gear 237 .

[0042] The mounting plate 231 is mounted on the bottom surface of the carrier 201; the reciprocating screw 232 is rotatably mounted on the mounting plate 231; the moving seat 233 is sleeved on the reciprocating screw 232; the moving seat 233 can reciprocate horizontally along the reciprocating screw 232. The cleaning brush 234 is fixedly sleeved on the moving seat 233, and the cleaning brush 234 is in contact with the track 100; the guide plate 235 is mounted on the mounting plate 231, and the guide plate 235 penetrates the cleaning brush 234 and is slidably connected with the cleaning brush 234. The driven gear 236 is mounted on the end of the reciprocating screw 232 away from the mounting plate 231; the driving gear 237 is mounted on the moving wheel 222, and the driving gear 237 is meshed and connected with the driven gear 236.

[0043] Specifically, when the moving wheel 222 rotates, it will drive the driving gear 237 to rotate, and then mesh and drive the driven gear 236 to rotate, and then drive the reciprocating screw 232 to rotate, and then make the moving seat 233 reciprocate horizontally along the reciprocating screw 232. When the moving seat 233 moves, it will drive the cleaning brush 234 to move, so that the cleaning brush 234 cleans the track 100, thereby cleaning up the debris attached to the track 100, making it easier for the moving wheel 222 to connect with the track 100, thereby improving the stability of the carrier 201 when moving, thereby improving the stability when transporting thermal power generation facilities. And through the reciprocating horizontal movement of the cleaning brush 234, the cleaning range of the cleaning brush 234 can be significantly expanded, and the reciprocating cleaning brush 234 can also contact and remove the debris on the track 100 more frequently, improving the cleaning efficiency and cleaning effect.

[0044] like Figure 3 As shown, the positioning and conveying mechanism 200 further includes a limiting assembly 210, which includes four hydraulic cylinders 211 and two clamping plates 212. The four hydraulic cylinders 211 are respectively mounted on the inner wall of the carrier 201; the two clamping plates 212 are fixedly connected to the extended ends of the two hydraulic cylinders 211.

[0045] Specifically, after the thermal power generation facility is placed on the carrier 201, the four hydraulic cylinders 211 are started to drive the two clamps 212 to move in opposite directions, so that the two clamps 212 clamp and fix the thermal power generation facility, thereby preventing the thermal power generation facility from sliding during transportation, thereby improving the stability and safety of transportation.

[0046] Working principle: When in use, the thermal power generation facility to be transported is placed on the carrier 201, and then the four hydraulic cylinders 211 are started to drive the two clamping plates 212 to move in opposite directions, so that the two clamping plates 212 clamp and fix the thermal power generation facility.

[0047] Then, by starting the motor reducer 223, a shaft rod 221 is driven to rotate, which in turn drives the two moving wheels 222 to rotate, and then drives the carrier 201 to move along the two tracks 100, thereby driving the thermal power generation facility to move.

[0048] When the moving wheel 222 rotates, it drives the driving gear 237 to rotate, and then meshes and drives the driven gear 236 to rotate, and then drives the reciprocating screw 232 to rotate, and then makes the moving seat 233 reciprocate horizontally along the reciprocating screw 232. When the moving seat 233 moves, it drives the cleaning brush 234 to move, and then makes the cleaning brush 234 clean the track 100, thereby cleaning up the debris attached to the track 100, making it easier for the moving wheel 222 to connect with the track 100, thereby improving the stability of the carrier 201 when moving, thereby improving the stability when transporting thermal power generation facilities. And through the reciprocating horizontal movement of the cleaning brush 234, the cleaning range of the cleaning brush 234 is significantly expanded, and the reciprocating cleaning brush 234 can also contact and remove the debris on the track 100 more frequently, improving the cleaning efficiency and cleaning effect.

[0049] When the support frame 201 and the thermal power generation facility it supports reach the specified position, by starting the second motor 244, the power output shaft of the second motor 244 will drive the cam 245 to rotate, and the rotating cam 245 will move the two movable plates 241 in opposite directions, thereby causing the two tooth plates 242 to engage with the two fixed racks 101 respectively, so that the moving wheel 222 cannot move along the track 100, thereby fixing the support frame 201 on the track 100.

[0050] Example 2: Figure 1-Figure 7 As shown, while other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that the positioning and conveying equipment for installing thermal power generation facilities also includes a control system.

[0051] The control system includes: a data collection module, a data analysis module, a data acquisition module and an acceleration / deceleration prediction module. The modules are connected by wired / wireless means to realize data transmission.

[0052] The data acquisition module is used to collect comprehensive data information of the positioning and conveying equipment, wherein the comprehensive data information includes weight data, volume data and track 100 flatness data.

[0053] Specifically, the weight data refers to the weight of the thermal power generation facility on the carrier 201, and the weight data is obtained by measuring with a weight sensor.

[0054] The volume data refers to the volume of the thermal power generation facility on the carrier 201. The volume data can be obtained by measuring the length, width, and height data of the thermal power generation facility with a tape measure or a laser rangefinder, and then multiplying the length, width, and height data to obtain the volume data of the thermal power generation facility. When the shape of the thermal power generation facility is complex, the length, width, and height data of the thermal power generation facility adopt the maximum length, maximum width, and maximum height of the thermal power generation facility.

[0055] Track 100 flatness data can be measured and calculated using a laser rangefinder, as follows:

[0056] First, set the elevation reference plane of the track top surface. The preset elevation reference plane is a specific value.

[0057] Then, a plurality of measuring points are set at equal intervals on the track 100, and a laser rangefinder is used to measure the height of the top surface of the track 100 at each measuring point;

[0058] Then, the value of the measured top surface of the track 100 is subtracted from the preset elevation reference surface value to obtain the elevation difference, and the absolute value of the elevation difference is the flatness data of the measuring point;

[0059] Then, the average of the flatness data of the multiple measurement points is calculated, and the average is the track 100 flatness data at this time.

[0060] The data analysis module generates a stability influence coefficient based on the comprehensive data information, and generates a corresponding driving speed level based on the stability influence coefficient;

[0061] The stability influence coefficient is generated as follows:

[0062]

[0063] Wherein, Wd is the stability influence coefficient, Zl is the weight data of the thermal power generation facility on the carrier 201, Tj is the volume data of the thermal power generation facility on the carrier 201, Pz is the flatness data of the track 100, and are all weight coefficients, which are determined by technicians in this field according to specific application requirements. and All are greater than 0;

[0064] The greater the weight of the thermal power generation facility on the carrier 201, the greater the inertia, and the travel speed of the carrier 201 needs to be reduced to ensure the stability of the thermal power generation facility and the carrier 201, and vice versa.

[0065] The larger the volume of the thermal power generation facilities on the carrier 201, the more difficult it is to evenly distribute and fix the thermal power generation facilities on the carrier 201, which increases the instability during transportation. Moreover, the larger the volume, the more susceptible it will be to the impact of wind, generating greater wind resistance and roll force. Therefore, it is necessary to reduce the travel speed of the carrier 201 to ensure the stability of the thermal power generation facilities and the carrier 201, and vice versa.

[0066] The worse the flatness of the track 100 is, the more bumps the carrier 201 will experience when traveling on the track 100, thereby reducing the stability of the carrier 201 and the thermal power generation facility. Therefore, it is necessary to reduce the travel speed of the carrier 201 to ensure the stability of the thermal power generation facility and the carrier 201; conversely, the higher the flatness of the track 100 is, the better the stability of the carrier 201 and the thermal power generation facility is, and the travel speed of the carrier 201 can be increased.

[0067] It should be noted that the formulas involved in the above-mentioned are all calculated by removing dimensions and taking numerical values. They are a formula that is closest to the actual situation obtained by collecting a large amount of data and performing software simulation. The weight coefficients in the formulas and the various preset thresholds in the analysis process are set by technical personnel in this field according to actual conditions or obtained by simulating a large amount of data; the size of the weight coefficient is to quantify each parameter to obtain a specific value for subsequent comparison. The size of the weight coefficient depends on the amount of sample data and the corresponding processing coefficients initially set by technical personnel in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameters and the quantized values.

[0068] Driving speed levels are generated as follows:

[0069] The driving speed levels include a first-level driving speed, a second-level driving speed and a third-level driving speed, wherein the first-level driving speed, the second-level driving speed and the third-level driving speed increase in sequence, and the first-level driving speed, the second-level driving speed and the third-level driving speed are all driving speeds of the carrier 201;

[0070] The preset threshold range of the stability influence coefficient is Wd1, Wd2, Wd1 <Wd2;

[0071] If Wd≤Wd1, it is determined that the stability of the carrier 201 and the thermal power generation facility is poor, and at this time, the data analysis module generates a first-level driving speed signal;

[0072] If Wd2≥Wd>Wd1, it is determined that the stability of the carrier 201 and the thermal power generation facility is average, and at this time, the data analysis module generates a secondary driving speed signal;

[0073] If Wd>Wd2, it is determined that the stability of the carrier 201 and the thermal power generation facility is good. At this time, the data analysis module generates a third-level driving speed signal.

[0074] Wherein, Wd1 and Wd2 are determined by those skilled in the art according to specific application requirements.

[0075] According to the corresponding driving speed level, the data analysis module generates a corresponding driving speed level control signal. For example, when the driving speed level is the first driving speed, the data analysis module will generate a first driving speed control signal, and then send the first driving speed control signal to the controller of the motor reducer 223, thereby controlling and adjusting the rotation speed of the motor reducer 223, and then adjusting the rotation speed of the shaft 221 and the moving wheel 222, thereby adjusting the driving speed of the carrier 201.

[0076] The data acquisition module is used to collect a historical training data set of the positioning conveying equipment, and the historical training data set includes the comprehensive impact data of the driving speed and the acceleration and deceleration of the carrier 201; wherein the comprehensive impact data of the driving speed includes comprehensive data information and the driving speed data of the carrier 201, and the driving speed of the carrier 201 can be measured by a speed sensor;

[0077] The acceleration and deceleration of the carrier 201 refer to the acceleration during the acceleration process and the deceleration during the deceleration process of the carrier 201. The acceleration and deceleration of the carrier 201 can be monitored and obtained in real time using an acceleration sensor.

[0078] The acceleration / deceleration prediction module trains a machine learning model for predicting the acceleration and deceleration of the carrier 201 based on a historical training data set, collects comprehensive impact data of the driving speed in real time, and inputs the data into the trained machine learning model to predict the acceleration and deceleration of the carrier 201;

[0079] The training method of the machine learning model for predicting the acceleration and deceleration of the carrier 201 includes:

[0080] Convert the collected driving speed comprehensive impact data into a corresponding set of feature vectors;

[0081] Each set of feature vectors is used as the input of the machine learning model. The machine learning model takes the acceleration and deceleration of the carrier 201 corresponding to each set of driving speed comprehensive impact data as output, takes the acceleration and deceleration of the carrier 201 actually corresponding to each set of driving speed comprehensive impact data as the prediction target, and takes minimizing the loss function value of the machine learning model as the training target; training stops when the loss function value of the machine learning model is less than or equal to the preset target loss value.

[0082] The machine learning model can be one of the models such as SVM regression, random forest regression or neural network regression.

[0083] The loss function value of the machine learning model is the mean square error;

[0084] Mean square error is one of the commonly used loss functions. Minimization is used as the goal to train the model so that the machine learning model better fits the data, thereby improving the performance and accuracy of the model;

[0085] In the loss function, MSE is the loss function value of the machine learning model, x is the feature vector group number; m is the number of feature vector groups; y is the number of feature vector groups; x is the acceleration and deceleration of the carrier 201 predicted by the xth group of eigenvectors, are the acceleration and deceleration of the carrier 201 actually corresponding to the x-th group of eigenvectors;

[0086] Other model parameters of the machine learning model, target loss value, optimization algorithm, training set test set validation set ratio, and loss function optimization are all achieved through actual engineering implementation and continuous experimental tuning.

[0087] The acceleration and deceleration processes of the motor reducer 223 are controlled according to the predicted acceleration and deceleration of the carrier 201, so as to smoothly adjust the acceleration and deceleration of the carrier 201 to adapt to different transportation requirements and stability conditions.

[0088] In summary, the control system obtains comprehensive data information of the equipment through the data acquisition module, including weight data, volume data and track 100 flatness data, generates a stability influence coefficient based on this information, and determines and generates a corresponding travel speed level, thereby adjusting the travel speed of the carrier 201 to ensure the stability of the thermal power generation facility and the carrier 201. Under the premise of ensuring stability, the control system can increase the travel speed of the carrier 201, thereby shortening the transportation time and improving the transportation efficiency.

[0089] The acceleration and deceleration prediction module in the control system trains a machine learning model that predicts the acceleration and deceleration of the carrier 201 based on a historical training data set, collects comprehensive impact data of driving speed in real time, and inputs the data into the trained machine learning model to predict the acceleration and deceleration of the carrier 201, thereby smoothly adjusting the acceleration and deceleration of the carrier 201 to adapt to different transportation needs and stability conditions.

[0090] Example 3: Figure 1-Figure 6 As shown, the method for using the positioning and conveying equipment for installing a thermal power generation facility comprises the following steps:

[0091] Step 1: Ensure that the two rails 100 and the two fixed racks 101 are firmly installed on the ground, and the fixed rack 101 is located between the two rails 100; stably place the thermal power generation facilities to be transported on the carrier 201 to ensure that the equipment is stable and will not slide;

[0092] Step 2: Start the four hydraulic cylinders 211 on the inner wall of the carrier 201, so that the extended ends of the hydraulic cylinders 211 drive the two clamping plates 212 to move in opposite directions, so that the two clamping plates 212 clamp and fix the thermal power generation facility;

[0093] Step 3: Start the motor reducer 223, the motor reducer 223 will drive the shaft 221 connected thereto to rotate, the rotation of the shaft 221 will drive the moving wheels 222 installed at both ends to rotate, and then drive the carrier 201 to move along the two tracks 100;

[0094] Step 4: When the carrier 201 moves, the rotation of the moving wheel 222 will drive the driving gear 237 to rotate, and the meshing connection between the driving gear 237 and the driven gear 236 will drive the reciprocating screw 232 to rotate. The rotation of the reciprocating screw 232 will cause the moving seat 233 to reciprocate horizontally, thereby driving the cleaning brush 234 to clean the upper surface of the track 100;

[0095] Step five, when the support frame 201 and the thermal power generation facility it supports reach the designated position, stop the operation of the motor reducer 223, and then start the second motor 244. The power output shaft of the second motor 244 will drive the cam 245 to rotate, and the rotating cam 245 will push the two movable plates 241 to move in opposite directions, thereby causing the toothed plate 242 installed on the movable plate 241 to engage with the two fixed racks 101, so that the support frame 201 is fixed on the track 100.
