Description

Technical Field

[0001] The present application relates to the field of intelligent warehousing technology, and in particular to a material transport vehicle. Background Art

[0002] With the rapid development of my country's economy, the degree of automation in manufacturing production is getting higher and higher. In order to improve the transportation of storage materials, intelligent material transport vehicles are usually used to improve the transportation speed and accuracy of materials. When transporting materials with high density and small size, the friction between the materials and the material transport vehicle is relatively large, and they generally will not fall during the transfer process. However, when transporting materials with low density and large size, the friction between the materials and the platform is relatively small, and they are very easy to fall during the transfer process, so they need to be protected. However, the material transport vehicles for intelligent storage on the existing market generally use pallets or towing mobile carts to transport materials. The structure and function of this material transport vehicle are relatively simple. When transporting materials with low density and large size or transporting materials with high density and small size, it is impossible to classify and protect the transported materials, thereby failing to ensure the stability of the material transport vehicle in transporting materials. At the same time, when transporting materials in storage, the material transport vehicle is often pushed away or stolen by others without permission. Therefore, it is necessary to design a material transport vehicle to solve the above problems. Summary of the invention

[0003] The embodiment of the present application provides a material transport vehicle to improve the problem that the existing material transport vehicles cannot ensure the stability of transporting materials.

[0004] In the first aspect, an embodiment of the present application provides a material transport vehicle, including a traveling vehicle, a first label, a second label, an identification component, a guardrail and a driving device; a label hole is provided on the traveling vehicle, and the traveling vehicle has a first traveling wheel; the identification component is provided on the traveling vehicle, and the identification component is used to generate a first identification signal when the first label is inserted into the label hole alone, and the identification component is also used to generate a second identification signal when the second label is inserted into the label hole alone; the guardrail can be raised and lowered on the traveling vehicle, and the guardrail has a first position extending out of the traveling vehicle and a second position retracted in the traveling vehicle; the driving device is used to respond to the first identification signal to drive the guardrail to rise from the second position to the first position, and the driving device is also used to respond to the second identification signal to drive the guardrail to descend from the first position to the second position.

[0005] In the above technical solution, a label hole and an identification component are provided on the traveling vehicle, and the identification component can generate a first identification signal or a second identification signal by inserting the first label or the second label into the label hole separately, so that the driving device can drive the guardrail to rise or fall relative to the traveling vehicle according to the first identification signal or the second identification signal, so as to switch the guardrail between the first position and the second position, so that different protective measures can be adopted according to different materials placed on the traveling vehicle. The material transport vehicle of this structure has a simple structure and multiple functions. It can classify and protect the transported materials when transporting materials with low density and large size or materials with high density and small size, thereby ensuring the stability of the material transport vehicle in transporting materials.

[0006] In addition, the material transport vehicle provided in the embodiment of the present application also has the following additional technical features:

[0007] Furthermore, the first label has a first identification channel and a first blocking area; the identification component is used to identify the first identification channel and the first blocking area to generate the first identification signal; the second label has a second identification channel and a second blocking area, and the identification component is used to identify the second identification channel and the second blocking area to generate the second identification signal.

[0008] In the above technical solution, by setting the first identification channel and the first blocking area on the first label, and setting the second identification channel and the second blocking area on the second label, the identification component can generate different identification signals according to the first label and the second label, thereby controlling the rise or fall of the guardrail. The first label and the second label using this distinction method have a simple structure, are easy to implement, and are stable and reliable.

[0009] Furthermore, the first tag has a first top block; the second tag has a second top block; the material transport vehicle also includes a first braking mechanism that cooperates with the first top block or the second top block; the first braking mechanism is arranged on the traveling vehicle, and the first braking mechanism has a braking state that prevents the traveling vehicle from walking and a moving state that allows the traveling vehicle to walk; when the first tag is inserted into the tag hole alone or the second tag is inserted into the tag hole alone, the first top block or the second top block is used to trigger the first braking mechanism to put the first braking mechanism in the moving state; when the first tag and the second tag exit the tag hole, the first braking mechanism is in the braking state.

[0010] In the above technical solution, the material transport vehicle is also provided with a first braking mechanism, so that when the first label or the second label is inserted into the label hole alone, the first top block of the first label or the second top block of the second label can also control the action of the first braking mechanism, so that the first braking mechanism allows the traveling vehicle to move, and after the first label and the second label exit the label hole, the first braking mechanism can prevent the traveling vehicle from moving, thereby realizing mechanical linkage control of the first braking mechanism through the first label or the second label to drive the traveling vehicle to switch between the braking state and the moving state, and thus there is no need for the operator to additionally open or close the first braking mechanism, which is easy to operate, saves operation time, and improves the transportation efficiency of materials.

[0011] Furthermore, the first label also includes a first label body and a first guide rod; the first label body is used for identification by the identification component to generate the first identification signal; the first label body and the first top block are connected via the first guide rod; the second label also includes a second label body and a second guide rod; the second label body is used for identification by the identification component to generate the second identification signal; the second label body and the second top block are connected via the second guide rod.

[0012] In the above technical solution, by connecting the first guide rod to the first label body, and connecting the first top block to the end of the first guide rod away from the first label body, so that when the first label is inserted into the label hole, the first top block is pushed to trigger the first brake mechanism, so that the first guide rod plays a guiding and transmission role. Similarly, by connecting the second guide rod to the second label body, and connecting the second top block to the end of the second guide rod away from the second label body, so that when the second label is inserted into the label hole, the second top block is pushed to trigger the first brake mechanism, so that the second guide rod plays a guiding and transmission role. The first label and the second label using this structure are simple in structure, easy to implement, and stable and reliable.

[0013] Furthermore, the first braking mechanism includes a brake pad, an elastic member and a transmission assembly; the brake pad is rotatably connected to the traveling vehicle, and the elastic member and the transmission assembly are both connected to the brake pad; when the first braking mechanism is in the braking state, the brake pad brakes the first traveling wheel under the action of the elastic member; when the first label or the second label is inserted into the label hole, the first top block or the second top block can push the transmission assembly to overcome the elastic force of the elastic member so that the brake pad releases the first traveling wheel.

[0014] In the above technical solution, the first brake mechanism is provided with a brake pad, an elastic member and a transmission assembly. When the first tag or the second tag is not inserted into the tag hole, the brake pad can rotate relative to the traveling vehicle in the positive direction under the elastic force of the elastic member to be pressed against the first traveling wheel, thereby realizing the braking effect of the first brake mechanism on the traveling vehicle. When the first tag is inserted into the tag hole alone or the second tag is inserted into the tag hole alone, the first top block or the second top block can push the transmission assembly to overcome the elastic force of the elastic member and drive the brake pad to rotate in the opposite direction relative to the traveling vehicle, so that the brake pad leaves the first traveling wheel, thereby realizing the brake pad releasing the first traveling wheel and allowing the traveling vehicle to travel.

[0015] Furthermore, the transmission assembly includes a moving block and a brake line; the moving block is movably arranged on the traveling vehicle, the moving block and the brake pad are connected to each other through the brake line transmission, and the moving block is pushed by the first top block or the second top block to drive the brake pad to rotate relative to the traveling vehicle to release the first traveling wheel.

[0016] In the above technical solution, the transmission component includes a moving block and a brake line, one end of the brake line is connected to the moving block, and the other end is connected to the brake pad. The moving block can be pushed to move relative to the traveling vehicle through the first top block or the second top block, thereby driving the brake line to move, so as to drive the brake pad to rotate relative to the traveling vehicle, and then the power of the first tag or the second tag is transmitted to the brake pad through the transmission component to trigger the action of the first braking mechanism.

[0017] Furthermore, the material transport vehicle also includes a second braking mechanism; the second braking mechanism is arranged on the traveling vehicle, the second braking mechanism is electrically connected to the identification component, and the second braking mechanism is used to respond to the first identification signal or the second identification signal to release the first traveling wheel.

[0018] In the above technical solution, the material transport vehicle is also provided with a second brake mechanism, which can respond to the first identification signal or the second identification signal to release the first travel wheel, thereby allowing the vehicle to move. When the first tag or the second tag is not inserted into the tag hole, that is, when the second brake mechanism cannot receive the first identification signal or the second identification signal, the second brake mechanism brakes the first travel wheel to prevent the material transport vehicle from being pushed away or stolen by others without permission when storing and transporting materials. Therefore, the material transport vehicle adopting this structure can further lock the vehicle to prevent others from maliciously damaging the first brake mechanism to make it unstable, or using foreign objects to unlock the first brake mechanism through the transmission assembly, thereby causing the material transport vehicle to be stolen.

[0019] Furthermore, the identification component includes an infrared transmitter and an infrared receiver; the infrared transmitter is used to emit a first infrared ray and a second infrared ray; when the first label is inserted into the label hole alone, the first blocking area blocks the first infrared ray, and the infrared receiver receives the second infrared ray passing through the first identification channel to generate the first identification signal; when the second label is inserted into the label hole alone, the second blocking area blocks the second infrared ray, and the infrared receiver receives the first infrared ray passing through the second identification channel to generate the second identification signal.

[0020] In the above technical solution, the identification component includes an infrared transmitter and an infrared receiver. In actual use, the infrared transmitter can emit two infrared rays, namely a first infrared ray and a second infrared ray, and the first infrared ray and the second infrared ray can pass through the second identification channel and the first identification channel respectively. When the first label is inserted into the label hole alone, the infrared receiver can only receive the second infrared ray passing through the first identification channel, and the first infrared ray is blocked by the first blocking area. When the second label is inserted into the label hole, the infrared receiver can only receive the first infrared ray passing through the second identification channel, and the second infrared ray is blocked by the second blocking area, so that the infrared receiver can generate the first identification signal or the second identification signal according to the different infrared rays received. This identification mode has high stability and is not prone to identification errors.

[0021] Furthermore, the material transport vehicle also includes a monitoring device and an alarm device; the monitoring device and the alarm device are both arranged on the traveling vehicle; the monitoring device is used to monitor the material placed on the traveling vehicle, and generate a monitoring signal when the material is separated from the traveling vehicle; the alarm device is used to respond to the monitoring signal to alarm.

[0022] In the above technical solution, the monitoring device installed on the traveling vehicle can monitor the materials placed on the traveling vehicle, and when the materials on the traveling vehicle fall, a monitoring signal can be generated to make the alarm device sound an alarm, thereby realizing the early warning function of the material transport vehicle and ensuring the safety of the materials.

[0023] The beneficial effect of the present application is that the material transport vehicle adopting this structure can insert the first label or the second label separately in the label hole according to different categories of materials, so that the identification component generates different identification signals, so that the driving device drives the guardrail to switch between the first position and the second position according to different identification signals, thereby classifying and protecting the transported materials, and improving the stability of the transported materials. And only when the first label or the second label is inserted separately in the label hole, the first top block of the first label or the second top block of the second label can push the moving block connected to the brake pad to trigger the brake pad of the first brake mechanism to release the first travel wheel, thereby realizing the mechanical unlocking of the travel vehicle, and the second brake mechanism responds to the first identification signal generated by the identification component after the first label is inserted or the second identification signal generated by the identification component after the second label is inserted to release the first travel wheel, thereby realizing the electronic unlocking of the travel vehicle to allow the material transport vehicle to move. By cooperating the first tag or the second tag with the above structure with the traveling vehicle, the classification and protection of materials during material transportation can be achieved. At the same time, through the cooperation of the first top block of the first tag or the second top block of the second tag with the first braking mechanism and the response of the second braking mechanism to the first identification signal or the second identification signal, the mechanical and electronic dual unlocking of the traveling vehicle can be achieved to prevent the material transport vehicle from being pushed away or stolen by others without permission.

[0038] Example

[0039] The embodiment of the present application provides a material transport vehicle 200, which can classify and protect the transported materials, thereby improving the stability of the material transport vehicle 200 in transporting materials. The specific structure of the material transport vehicle 200 is described in detail below with reference to the accompanying drawings.

[0040] Combination Figure 1 and Figure 2 As shown, the material transport vehicle 200 includes a vehicle 10, a first tag 20, a second tag 30 (not shown in the figure), an identification component 40, a guardrail 50 and a driving device 60. A tag hole 11 is provided on the vehicle 10. The identification component 40 is provided on the vehicle 10, and the identification component 40 is used to generate a first identification signal when the first tag 20 is inserted into the tag hole 11 alone, and the identification component 40 is used to generate a second identification signal when the second tag 30 is inserted into the tag hole 11 alone. The guardrail 50 is liftably provided on the vehicle 10, and the guardrail 50 has a first position extending out of the vehicle 10 and a second position retracted in the vehicle 10. The driving device 60 is used to respond to the first identification signal to drive the guardrail 50 to rise from the second position to the first position, and the driving device 60 is also used to respond to the second identification signal to drive the guardrail 50 to descend from the first position to the second position.

[0041] The traveling vehicle 10 is provided with a label hole 11 and an identification component 40. By inserting the first label 20 or the second label 30 into the label hole 11, the identification component 40 can generate a first identification signal or a second identification signal, so that the driving device 60 can drive the guardrail 50 to rise or fall relative to the traveling vehicle 10 according to the first identification signal or the second identification signal, so as to switch the guardrail 50 between the first position and the second position, so that different protection measures can be adopted according to different materials placed on the traveling vehicle 10. The material transport vehicle 200 of this structure has a simple structure and multiple functions. It can classify and protect the transported materials when transporting materials with low density and large size or materials with high density and small size, thereby ensuring the stability of the material transport vehicle 200 in transporting materials.

[0042] Among them, a control box 70 is also provided on the material transport vehicle 200, and the identification component 40 and the drive device 60 are electrically connected to the control box 70. After the identification component 40 generates a first identification signal or a second identification signal, the control box 70 can control the drive device 60 to operate according to the first identification signal or the second identification signal to drive the guardrail 50 to rise or fall.

[0043] Exemplarily, the driving device 60 is a cylinder, the cylinder body of the cylinder is fixed to the traveling vehicle 10, the guardrail 50 is escalably arranged on the traveling vehicle 10, and the guardrail 50 is connected to the output end of the cylinder, so that the guardrail 50 can be driven to rise or fall relative to the traveling vehicle 10. In other embodiments, the driving device 60 can also be a motor and a rack, the motor is connected to the traveling vehicle 10, the guardrail 50 is escalably arranged on the traveling vehicle 10, the rack is connected to the guardrail 50, and the gear arranged on the output end of the motor is meshed with the rack, thereby driving the guardrail 50 to rise or fall relative to the traveling vehicle 10.

[0044] In this embodiment, combined with Figure 1 and Figure 3 As shown, the traveling vehicle 10 includes a base 12, a mounting seat 13 and a transfer mechanism 14. The base 12 is used to place the materials to be transported, and the guardrail 50 is arranged on the base 12 in a liftable manner. The guardrail 50 is arranged circumferentially on the base 12 to protect the materials placed on the base 12. The mounting seat 13 is connected to the base 12, and the mounting seat 13 and the base 12 form an L-shaped structure. The identification component 40 and the label hole 11 are both arranged on the mounting seat 13. The transfer mechanism 14 is arranged at the bottom of the base 12, and the transfer mechanism 14 is used to drive the base 12 to move.

[0045] Furthermore, combined with Figure 1 and Figure 4As shown, the transfer mechanism 14 includes two first running wheels 141, two second running wheels 142, a driving assembly 143 and a guiding device. The two first running wheels 141 are both rotatably connected to the base 12, and the two first running wheels 141 are arranged at intervals and in parallel at the front end of the base 12. The driving assembly 143 is used to drive the first running wheels 141 to rotate relative to the base 12 to drive the base 12 to move. The two second running wheels 142 are both rotatably connected to the base 12, and the two second running wheels 142 are arranged at intervals and in parallel at the rear end of the base 12. Both the second running wheels 142 are universal wheels. The guiding device is installed on the base 12. The guiding device can scan the QR code posted on the ground to determine the current position of the walking vehicle 10 and judge the direction of travel of the walking vehicle 10, thereby realizing the automatic guiding function of the walking vehicle 10. The specific structure of the guiding device can refer to the relevant technology and will not be repeated here.

[0046] The driving assembly 143 includes two driving members 1431, both of which are motors. The motors correspond to the first running wheels 141 one by one. Each first running wheel 141 is provided with a motor, and each motor is used to drive the corresponding first running wheel 141 to rotate relative to the base 12. The transfer mechanism 14 with such a structure realizes the automatic turning function of the traveling vehicle 10. When turning is required, the two first running wheels 141 have a differential speed through the different rotation speeds of the two motors, so as to realize the turning function of the traveling vehicle 10. In other embodiments, the driving member 1431 may also be a hydraulic motor or the like.

[0047] In this embodiment, Figure 5 As shown, the first tag 20 includes a first tag body 21, a first guide rod 22 and a first top block 23. The first tag body 21 has a first identification channel 211 and a first blocking area 212. The identification component 40 is used to identify the first identification channel 211 and the first blocking area 212 to generate a first identification signal. The first tag body 21 and the first top block 23 are connected by the first guide rod 22. Figure 6As shown, the second tag 30 includes a second tag body 31, a second guide rod 32 and a second top block 33. The second tag body 31 has a second identification channel 311 and a second blocking area 312, and the identification component 40 is used to identify the second identification channel 311 and the second blocking area 312 to generate a second identification signal. The second tag body 31 and the second top block 33 are connected through the second guide rod 32. By setting the first identification channel 211 and the first blocking area 212 on the first tag body 21, and setting the second identification channel 311 and the second blocking area 312 on the second tag body 31, the identification component 40 can generate different identification signals according to the first tag 20 and the second tag 30, thereby controlling the rise or fall of the guardrail 50. The first tag 20 and the second tag 30 using this distinction method are simple in structure, easy to implement, and stable and reliable.

[0048] Among them, Figure 2 As shown, the identification component 40 includes an infrared transmitter 41 and an infrared receiver 42. The infrared transmitter 41 and the infrared receiver 42 are arranged relatively in the label hole 11 on the mounting seat 13, and the infrared transmitter 41 is used to emit the first infrared ray and the second infrared ray. When the first label 20 is inserted into the label hole 11 alone, the first blocking area 212 blocks the first infrared ray, and the infrared receiver 42 receives the second infrared ray passing through the first identification channel 211 to generate a first identification signal. When the second label 30 is inserted into the label hole alone, the second blocking area 312 blocks the second infrared ray, and the infrared receiver 42 receives the first infrared ray passing through the second identification channel 311 to generate a second identification signal.

[0049] During actual use, the infrared transmitter 41 can emit two infrared rays, namely the first infrared ray and the second infrared ray, which can pass through the second identification channel 311 and the first identification channel 211 respectively. When the first label 20 is inserted into the label hole 11 alone, the infrared receiver 42 can only receive the second infrared ray passing through the first identification channel 211, and the first infrared ray is blocked by the first blocking area 212. When the second label 30 is inserted into the label hole 11, the infrared receiver 42 can only receive the first infrared ray passing through the second identification channel 311, and the second infrared ray is blocked by the second blocking area 312, so that the infrared receiver 42 can generate the first identification signal or the second identification signal according to the different infrared rays received. This identification mode has high stability and is not prone to identification errors.

[0050] Optionally, combined Figure 2 , Figure 5 and Figure 6As shown, the first tag body 21 is also connected to a first drawstring 24, and the second tag body 31 is also connected to a second drawstring 34. When the first tag 20 or the second tag 30 is inserted into the tag hole 11, the first drawstring 24 or the second drawstring 34 is used to pull the first tag 20 or the second tag 30 out of the tag hole 11, which has a simple structure and is easy to operate.

[0051] It should be noted that, in other embodiments, the identification component 40 can also be other structures. For example, the identification component 40 is a barcode scanner arranged in the label hole 11, and different label codes are respectively arranged on the first label body 21 and the second label body 31. Therefore, when the first label 20 is inserted alone or the second label 30 is inserted alone in the label hole 11, the identification component 40 can generate different identification signals according to the different label codes on the first label body 21 or the second label body 31.

[0052] In this embodiment, combined with Figure 1 and Figure 7 As shown, the material transport vehicle 200 also includes a first braking mechanism 80. The first braking mechanism 80 is provided on the traveling vehicle 10, and the first braking mechanism 80 has a braking state for preventing the traveling vehicle 10 from traveling and a traveling state for allowing the traveling vehicle 10 to travel. When the first tag 20 is inserted into the tag hole 11 alone, the first top block 23 can trigger the first braking mechanism 80 so that the first braking mechanism 80 is in the traveling state. When the second tag 30 is inserted into the tag hole 11 alone, the second top block 33 can trigger the first braking mechanism 80 so that the first braking mechanism 80 is in the traveling state. When the first tag 20 and the second tag 30 exit the tag hole 11, the first braking mechanism 80 is in the braking state.

[0053] When the first label 20 or the second label 30 is inserted into the label hole 11 alone, the first brake mechanism 80 can be controlled to operate, so that the first top block 23 or the second top block 33 triggers the first brake mechanism 80 to operate, so that the first brake mechanism 80 allows the traveling vehicle 10 to travel. After the first label 20 and the second label 30 exit the label hole 11, the first brake mechanism 80 can prevent the traveling vehicle 10 from traveling, thereby realizing mechanical linkage control of the first brake mechanism 80 through the first label 20 or the second label 30 to drive the traveling vehicle 10 to switch between the braking state and the traveling state, and thus, there is no need for the operator to additionally open or close the first brake mechanism 80, which is convenient to operate, saves operation time, and improves the transportation efficiency of materials.

[0054] Further, continue to combine Figure 1 and Figure 7As shown, the first brake mechanism 80 includes a brake pad 81, an elastic member 82 and a transmission assembly 83. The brake pad 81 is rotatably connected to the base 12, the two ends of the elastic member 82 are respectively connected to the base 12 and the brake pad 81, and the transmission assembly 83 is connected to the brake pad 81. When the first brake mechanism 80 is in a braking state, that is, when neither the first label 20 nor the second label 30 is inserted into the label hole 11, the brake pad 81 presses the first running wheel 141 under the action of the elastic member 82 to brake the first running wheel 141, thereby realizing the braking effect of the first brake mechanism 80 on the running vehicle 10. When the first label 20 is inserted into the label hole 11 alone or the second label 30 is inserted into the label hole 11 alone, the first top block 23 or the second top block 33 can push the transmission assembly 83 to operate, so as to overcome the elastic force of the elastic member 82 and allow the brake pad 81 to release the first running wheel 141.

[0055] The transmission assembly 83 includes a moving block 831 and a brake line 832. The moving block 831 is movably arranged on the traveling vehicle 10, and the moving block 831 is connected to the brake pad 81 through the brake line 832. The first top block 23 or the second top block 33 pushes the moving block 831 to drive the brake pad 81 to rotate relative to the traveling vehicle 10 to release the first traveling wheel 141. One end of the brake line 832 is connected to the moving block 831, and the other end is connected to the brake pad 81. By moving the moving block 831, the brake line 832 can be driven to move to drive the brake pad 81 to rotate relative to the traveling vehicle 10, so that the power of the first tag 20 or the second tag 30 is transmitted to the brake pad 81 through the transmission assembly 83 to control the action of the first brake mechanism 80.

[0056] That is to say, combined Figure 2 and Figure 7 As shown, when the first label 20 and the second label 30 exit the label hole 11, the moving block 831 is no longer restricted by the first top block 23 or the second top block 33, so that the brake line 832 no longer exerts a force on the brake pad 81, so that the brake pad 81 can rotate relative to the base 12 under the elastic force of the elastic member 82 to be pressed against the first traveling wheel 141, thereby realizing the braking effect of the first brake mechanism 80 on the traveling vehicle 10. Figure 2 and Figure 8 As shown, when the first label 20 is inserted into the label hole 11 alone or the second label 30 is inserted into the label hole 11 alone, the first top block 23 or the second top block 33 can push the moving block 831 to move relative to the mounting seat 13, thereby driving the brake line 832 to move relative to the mounting seat 13, so as to overcome the elastic force of the elastic member 82 and drive the brake pad 81 to rotate in the opposite direction relative to the walking vehicle 10, so that the brake pad 81 leaves the first walking wheel 141, and then the brake pad 81 releases the first walking wheel 141, allowing the walking vehicle 10 to move.

[0057] Exemplarily, the first top block 23 and the second top block 33 are both spherical structures, and the moving block 831 is also a spherical structure, so that the first top block 23 or the second top block 33 can easily push the moving block 831 to move relative to the mounting seat 13, thereby reducing resistance.

[0058] Exemplarily, the elastic member 82 is a spring, which is sleeved on the brake line 832 and has two ends respectively connected to the brake pad 81 and the base 12 .

[0059] Optionally, combined Figure 1 and Figure 7 As shown, the brake pad 81, the elastic member 82 and the brake line 832 are all two, and the two brake pads 81 are both rotatably connected to the base 12. The two brake pads 81 rotate relative to the base 12 to press the first running wheel 141, so as to improve the braking effect and stability of the running vehicle 10. The elastic member 82 and the brake line 832 correspond to the brake pads 81 one by one, and each brake pad 81 is connected to an elastic member 82 and a brake line 832. The ends of the two brake lines 832 away from the brake pads 81 are connected to the moving block 831, so that when the moving block 831 moves relative to the mounting seat 13, it can simultaneously drive the two brake lines 832 to move, thereby simultaneously driving the two brake pads 81 to rotate relative to the base 12. In other embodiments, the brake pad 81, the elastic member 82 and the brake line 832 can also be one.

[0060] In this embodiment, the material transport vehicle 200 further includes a second brake mechanism, which is disposed on the base 12 and is electrically connected to the identification component 40 via a control box 70. The control box 70 can control the second brake mechanism to release the first travel wheel 141 according to the first identification signal or the second identification signal.

[0061] That is, when neither the first tag 20 nor the second tag 30 is inserted into the tag hole 11, the identification component 40 cannot generate any identification signal, and the control box 70 does not generate any control command to the second brake mechanism, so that the second brake mechanism brakes the first travel wheel 141, so as to prevent the material transport vehicle 200 from being pushed away or stolen by others without permission when storing and transporting materials. When the first tag 20 is inserted into the tag hole 11 alone or the second tag 30 is inserted into the tag hole 11 alone, the identification component 40 can generate the first identification signal or the second identification signal, so that the control box 70 can control the second brake mechanism according to the first identification signal or the second identification signal, so that the second brake mechanism releases the first travel wheel 141, thereby allowing the vehicle 10 to move. The material transport vehicle 200 adopting this structure can further lock the traveling vehicle 10 through the second braking mechanism to prevent others from maliciously damaging the first braking mechanism 80 to make it unstable, or using foreign objects to unlock the first braking mechanism 80 through the transmission assembly 83. For example, inserting other stick-shaped objects into the label hole 11 to trigger the transmission assembly 83 and cause a mis-lock, thereby causing the material transport vehicle 200 to be stolen.

[0062] Exemplarily, the second brake mechanism is an electronic brake, which is electrically connected to the identification component 40 via a control box 70, and the control box 70 can control the action of the electronic brake according to the first identification signal or the second identification signal. The specific structure of the electronic brake can refer to the relevant prior art, and will not be repeated here.

[0063] In this embodiment, Figure 1 As shown, the material transport vehicle 200 also includes a monitoring device 90 and an alarm device 100. The monitoring device 90 and the alarm device 100 are both arranged on the traveling vehicle 10, and the monitoring device 90 and the alarm device 100 are both electrically connected to the control box 70. The monitoring device 90 is used to monitor the material placed on the traveling vehicle 10, and to generate a monitoring signal when the material is separated from the traveling vehicle 10. The alarm device 100 is used to respond to the monitoring signal to sound an alarm. The specific structures of the monitoring device 90 and the alarm device 100 can be referred to the relevant technology, and will not be repeated here.

[0064] The monitoring device 90 provided on the traveling vehicle 10 can monitor the materials placed on the traveling vehicle 10, and can generate a monitoring signal when the materials on the traveling vehicle 10 fall. The control box 70 can control the alarm device 100 to operate according to the monitoring signal, so that the alarm device 100 emits an alarm sound, thereby realizing the early warning function of the material transport vehicle 200 and ensuring the safety of the materials.

[0065] Furthermore, the material transport vehicle 200 is also provided with an alarm cancellation module. The alarm cancellation module is integrated into the control box 70, and the material receiving personnel can cancel the alarm sound emitted by the alarm device 100 through the alarm cancellation module. The alarm cancellation module provided on the traveling vehicle 10 can realize the correct reception of materials. When the material receiving personnel removes the materials on the traveling vehicle 10, the alarm device 100 will sound an alarm, and the alarm sound can be canceled by the correct material receiving personnel, thereby ensuring the correct reception of materials and preventing the materials from being taken by mistake during transportation.

[0066] Exemplarily, the alarm release module is a fingerprint release module integrated on the control box 70. The correct fingerprint information of the material receiving personnel is pre-entered on the control box 70. When the material receiving personnel receives the material, they can verify it through the fingerprint. After successful recognition, the alarm sound of the alarm device 100 can be released through the alarm release module on the control box 70. In other embodiments, the alarm release module can also be a password release module integrated on the control box 70. The material receiving personnel can enter a password into the control box 70 to release the alarm sound of the alarm device 100.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
