Description

Technical Field

[0001] The invention belongs to the technical field of automobile scales, and in particular relates to an electric rail automobile scale with anti-collision monitoring function. Background Art

[0002] Truck scales, also known as floor scales, are the main weighing equipment used by factories, mines, businesses, etc. for measuring bulk goods. When a truck needs to have its weight checked, it is moved onto the truck scale, and the truck scale can then check the weight of the truck. Existing trucks first load the goods onto the truck, drive the truck onto the truck scale, and the limit device set on the truck scale starts to move, fits against the wheels of the truck, and limits the position of the truck before the weight of the truck is checked. Since the goods of this application are difficult to install on and remove from the truck, the truck needs to be moved onto the truck scale, and the front wheels of the truck must fit with the limit device set on the truck scale before the goods can be installed on the truck, so that the weight of the truck can be checked while the goods are installed, ensuring that the weight of the truck does not exceed the weight limit.

When the truck moves to the moment when its front wheels are in contact with the limit plates, there is a possibility that the front wheels of the truck will collide with the vertical plates. Since the direction of the impact force is perpendicular to the surface of the vertical plates, there is a possibility that the impact force of the front wheels of the truck on the limit plates is too large, causing the structure of the limit plates to deform, thereby reducing the service life of the truck scale. Summary of the Invention

Any anti-collision component is used to be set in conjunction with the corresponding front wheel of the car; the length of the anti-collision block is greater than the width of the front wheel of the car.

[0010] As a preferred technical solution of the present invention, the anti-collision component further includes a monitoring module, which is arranged in the anti-collision shell and is used to monitor the distance between the bottom of the anti-collision shell and the anti-collision block.

[0011] As a preferred technical solution of the present invention, the anti-collision component also includes a horn module, which is communicatively connected to the monitoring module. The initial safety distance preset by the monitoring module is N, where N is greater than the maximum displacement occurring during the loading of the truck. The data actually monitored by the monitoring module is B. If N>B, the monitoring module continues to monitor; if N≤B, the monitoring module controls the horn module to issue an alarm.

[0012] As a preferred technical solution of the present invention, the driving unit includes a first connecting block, a first hinged rod, a second connecting block and a second hinged rod. The first connecting block is arranged at the bottom of the mobile platform, and the second connecting block is arranged at the bottom of the anti-collision plate. One end of the first hinged rod is hinged to the first connecting block, one end of the second hinged rod is hinged to the second connecting block, and the other end of the first hinged rod is hinged to the other end of the second hinged rod.

In addition, it should be noted that the anti-collision plate is set at an angle on the mobile platform, and the height of the anti-collision plate gradually increases in the direction of the truck's advance, and the lowest height of the anti-collision plate is the same as the surface height of the mobile platform; since the surface of the anti-collision plate and the surface of the mobile platform are set at an angle to each other, when the truck and the anti-collision plate are in contact with each other, the front wheels of the truck will have a tendency to move along the setting direction of the anti-collision plate, thereby reducing the impact force of the front wheels of the truck on the anti-collision plate, avoiding the structural deformation of the anti-collision plate, and solving the problem that the existing limit devices set on the truck scale are all vertically set limit plates. When the truck moves to the moment when its front wheels are in contact with the limit plates, there is a situation where the front wheels of the truck collide with the vertical plates. Since the direction of the impact force is perpendicular to the surface of the vertical plates, there is a situation where the impact force of the front wheels of the truck on the limit plates is too large, causing the structure of the limit plates to deform, thereby reducing the service life of the truck scale.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figures 1-10 This embodiment provides an electric rail truck scale with anti-collision monitoring, including a mobile platform 1 and a track 2, the track 2 is arranged directly below the loading bin 3, and the mobile platform 1 is slidably arranged on the track 2; it should be noted that, in this scheme, the interior of the loading bin 3 is filled with large-sized steel plates, and the weight of a single steel plate is from more than ten kilograms to dozens of kilograms; the loading bin 3 is provided with a unloading device, which is used to directly load the steel plates stored in the loading bin 3 onto the truck through the output port of the loading bin 3. Since the length of the truck is much larger than the size of a single steel plate, multiple steel plates can be stacked and arranged on the truck; at the same time, for the convenience of description, it is defined here that the cargo box of the truck is provided with a loading space, and the loading space is provided with several loading areas, and the several loading areas are arranged at equal intervals along the setting direction of the cargo box, and each loading area can be loaded with several stacked steel plates; in order to ensure that the loading area of ​​the truck can be accurately moved to the bottom of the output port of the loading bin 3, this solution is provided with a mobile platform 1 and a track 2, and the mobile platform 1 is slidably set on the track 2. Since the mobile platform 1 can move accurately on the track 2, when the truck moves to the mobile platform 1, the first loading area of ​​the truck is located directly below the output port of the loading bin 3, and the unloading device starts to load steel plates onto the truck. After the first loading area of ​​the truck is filled with steel plates, the mobile platform 1 slides along the track 2, so that another adjacent loading area of ​​the truck can be accurately moved to the bottom of the output port of the loading bin 3, so that the unloading device can stack the steel plates in the remaining loading areas of the truck. In addition, the mobile platform 1 of this solution also has a weighing function to ensure that the steel plates loaded on the truck do not exceed the weight limit requirements, avoiding the situation where the extra steel plates need to be taken out of the truck after the steel plates loaded on the truck are overweight.

[0022] According to the description of the above embodiment, in order to ensure that the truck can load steel plates smoothly, it is necessary to ensure that the first loading area of ​​the truck can be located directly below the output port of the loading bin 3, so it is necessary to limit the initial position of the truck on the mobile platform 1; based on this, the present solution also includes an anti-collision component 4, and the anti-collision component 4 includes an anti-collision plate 401. When the front wheels of the truck are in contact with the anti-collision plate 401, the first loading area of ​​the truck is located directly below the output port of the loading bin 3; by providing the anti-collision plate 401, when the front wheels of the truck are in contact with the anti-collision plate 401, it indicates that the truck has moved to the designated position of the mobile platform 1, and at this time, the first loading area of ​​the truck is located directly below the output port of the loading bin 3. In addition, it should be noted that the anti-collision plate 401 is set on the mobile platform 1 at an angle, and the height of the anti-collision plate 401 gradually increases along the direction of the truck's advance. The lowest height of the anti-collision plate 401 is slightly higher than the surface of the mobile platform 1. Since the diameter of the truck's wheel tires is large, it can be considered that the lowest height of the anti-collision plate 401 is approximately the same as the surface height of the mobile platform 1; since the surface of the anti-collision plate 401 and the surface of the mobile platform 1 are set at an angle to each other, when the truck and the anti-collision plate 401 are in contact with each other, the front wheel of the truck will move along the setting direction of the anti-collision plate 401. The tendency of movement, thereby reducing the impact force of the truck's front wheel on the anti-collision plate 401, avoiding the structural deformation of the anti-collision plate 401, and solving the problem that the existing limiting devices set on the truck scale are all vertically set limiting plates. When the truck moves to the moment when its front wheel is in contact with the limiting plate, there is a situation that the front wheel of the truck collides with the vertical plate. Since the direction of the impact force is perpendicular to the surface of the vertical plate, the impact force of the front wheel of the truck on the limiting plate is too large, causing the structure of the limiting plate to be deformed, thereby reducing the service life of the truck scale.

[0023] Furthermore, in order to facilitate the transportation of the truck scale, the truck scale of this scheme needs to ensure that the anti-collision plate 401 protruding from the top of the mobile platform 1 is retracted into the mobile platform 1 during the period when it is not in use or when it is transported from the production site to the place of use. Based on this, the mobile platform 1 of this scheme is provided with an anti-collision slot 101, and one end of the anti-collision plate 401 is rotatably hinged to the anti-collision slot 101. The anti-collision component 4 also includes a drive unit 5, which is arranged at the bottom of the mobile platform 1. The output end of the drive unit 5 is connected to the anti-collision plate 401, and the anti-collision plate 401 can lock or release its tilted cooperation relationship with the mobile platform 1; by providing the drive unit 5, the drive unit 5 is used to control the anti-collision plate 401 to rotate along its hinged end with the anti-collision slot 101, so that the surface height of the anti-collision plate 401 is equal to the surface height of the mobile platform 1, thereby realizing the retraction of the anti-collision plate 401 into the mobile platform 1.

[0024] According to the description of the above embodiment, it can be known that after the truck moves onto the mobile platform 1, the unloading device begins to load the steel plates in the loading bin 3 into the truck cargo box. Due to the large mass of the steel plates, the truck will shake during the period when the unloading device loads the steel plates into the truck cargo box. The shaking direction also includes the component shaking direction along the forward direction of the truck, and then the shaking of the truck will be transmitted to the front wheels of the truck, causing the anti-collision plate 401 and the drive unit 5 to vibrate; in order to prevent the connection structure between the anti-collision plate 401 and the drive unit 5 from loosening due to vibration, this solution needs to reduce the vibration force exerted on the drive unit 5 and the anti-collision plate 401. Based on this, the anti-collision plate 401 of this solution includes an anti-collision shell 402 with an opening at the top, an anti-collision block 403 and a sliding spring 404, and the anti-collision block 403 is slidably arranged at A sliding spring 404 is disposed within the anti-collision housing 402. The two ends of the sliding spring 404 are respectively connected to the anti-collision housing 402 and the anti-collision block 403. The anti-collision housing 402 is hinged to the anti-collision slot 101. The drive unit 5 controls the rotation of the anti-collision housing 402. With this arrangement, when the front wheel of the truck abuts against the anti-collision block 403, the vibration on the truck will be transmitted to the anti-collision block 403, and then the anti-collision block 403 will transmit the vibration to the sliding spring 404. Since the sliding spring 404 has the characteristic of storing kinetic energy, the sliding spring 404 will absorb the vibration from the anti-collision block 403, and the vibration transmitted to the anti-collision housing 402 will be weakened, thereby preventing the connection structure between the anti-collision housing 402 and the drive unit 5 from loosening due to vibration. It is worth noting that one end of the anti-collision block 403 of this solution protrudes from the anti-collision housing 402 and is used to limit the position of the front wheel of the truck.

[0025] Furthermore, since a truck has two front wheels, the present embodiment provides two sets of anti-collision assemblies 4, each corresponding to one of the two front wheels. Each anti-collision assembly 4 is configured to fit a corresponding front wheel. Furthermore, the length of the anti-collision block 403 is greater than the width of the front wheel. This arrangement ensures that the front end of the front wheel of the vehicle will abut against the anti-collision block 403.

[0026] Furthermore, in order to monitor the distance between the anti-collision block 403 and the anti-collision shell 402, the anti-collision component 4 of this solution also includes a monitoring module 405, which is arranged in the anti-collision shell 402 and is used to monitor the distance between the bottom of the anti-collision shell 402 and the anti-collision block 403.

[0027] In addition, the anti-collision component 4 of this solution also includes a horn module 406, which is in communication with the monitoring module 405. The initial safety distance preset by the monitoring module 405 is N (cm), where N (cm) is greater than the maximum displacement that occurs during the loading of the truck. The data actually monitored by the monitoring module 405 is B (cm). If N (cm) > B (cm), the monitoring module 405 continues to monitor; if N (cm) ≤ B (cm), the monitoring module 405 controls the horn module 406 to sound an alarm, indicating that the truck's forward position is too close, and signals the truck to move back a certain distance.

[0028] Specifically, the driving unit 5 of this solution includes a first connecting block 501, a first hinged rod 502, a second connecting block 503 and a second hinged rod 504. The first connecting block 501 is arranged at the bottom of the mobile platform 1, and the second connecting block 503 is arranged at the bottom of the anti-collision shell 402. One end of the first hinged rod 502 is hinged to the first connecting block 501, one end of the second hinged rod 504 is hinged to the second connecting block 503, and the other end of the first hinged rod 502 is hinged to the other end of the second hinged rod 504. The central axis of the first hinged rod 502 can be locked or released so that it coincides with the central axis of the second hinged rod 504. ; Through such a setting, when the surface of the anti-collision block 403 is parallel to the surface of the mobile platform 1, the first hinge rod 502 and the second hinge rod 504 are in an inclined state; as the first hinge rod 502 rotates, the first hinge rod 502 will drive the second hinge rod 504 to rotate until the first hinge rod 502 and the second hinge rod 504 are in a vertical state, and the central axis of the first hinge rod 502 and the central axis of the second hinge rod 504 are in a mutually overlapping state. At this time, the anti-collision block 403 rotates along the hinged end of the anti-collision shell 402 and the anti-collision slot 101, and is located at the top of the mobile platform 1, and is in a tilted state.

[0029] Furthermore, the driving unit 5 of the present embodiment also includes a sliding block 505 and a driving electric cylinder 506. The driving electric cylinder 506 is arranged at the bottom of the mobile platform 1. The side wall of the first hinged rod 502 is provided with a sliding groove 5021 along its axial direction. The sliding block 505 is slidably arranged on the sliding groove 5021. The output end of the driving electric cylinder 506 is hinged to the sliding block 505. By providing the driving electric cylinder 506, the output end of the driving electric cylinder 506 controls the rotation of the first hinged rod 502 through extension and contraction, thereby realizing the rotation of the anti-collision plate 401.

[0030] According to the description of the above embodiment, it can be known that after the truck is in contact with the anti-collision block 403, the impact force of the truck on the anti-collision block 403 and the vibration of the truck on the anti-collision block 403 will be transmitted to the first hinge rod 502 and the second hinge rod 504, thereby forcing the first hinge rod 502 and the second hinge rod 504 to rotate, thereby releasing the matching relationship between the first hinge rod 502 and the second hinge rod 504. In order to ensure the matching state between the first hinge rod 502 and the second hinge rod 504, the driving electric cylinder 506 needs to overcome the impact force of the truck on the anti-collision block 403 and the vibration of the truck on the anti-collision block 403. Therefore, in practice During operation, the driving electric cylinder 506 is easily damaged, and the service life of the driving electric cylinder 506 is often very short. Based on this, in order to solve this problem, the driving unit 5 of this solution also includes an adjusting hydraulic cylinder 507 and an adjusting slider 508. A vertical adjusting slot is provided at the bottom of the mobile platform 1. The adjusting slider 508 is slidably disposed in the adjusting slot. The adjusting slider 508 is hingedly disposed at one end of the driving electric cylinder 506 away from its output end. The adjusting hydraulic cylinder 507 is vertically disposed at the bottom of the mobile platform 1. The output end of the adjusting hydraulic cylinder 507 is connected to the adjusting slider 508. The driving electric cylinder 506 can lock or release its horizontally arranged cooperative relationship. By providing an adjusting hydraulic cylinder 507, when the driving electric cylinder 506 controls the first hinge rod 502 to rotate, so that the first hinge rod 502 and the second hinge rod 504 cooperate with each other, the driving electric cylinder 506 is in a tilted state; the adjusting hydraulic cylinder 507 starts to work, controlling the end of the driving electric cylinder 506 away from the output end to perform a lifting process, so that the driving electric cylinder 506 is transformed from the original tilted state to the horizontal state. At this time, the central axis of the driving electric cylinder 506 is perpendicular to the central axis of the first hinge rod 502. Through such an arrangement, the driving electric cylinder 506 is perpendicular to the first hinge rod 502 and the second hinge rod 504. 4, which results in the formation of a "dead angle" system between the driving electric cylinder 506, the first articulated rod 502 and the second articulated rod 504, restricting the first articulated rod 502 and the second articulated rod 504 from rotating any further. After the truck is in contact with the anti-collision block 403, the impact force of the truck on the anti-collision block 403 and the vibration of the truck on the anti-collision block 403 cannot change the matching relationship between the first articulated rod 502 and the second articulated rod 504. The driving electric cylinder 506 also does not need to apply additional working power to overcome the impact force from the truck on the anti-collision block 403 and the vibration of the truck on the anti-collision block 403, thereby further improving the working life of the driving electric cylinder 506.

[0031] Similarly, when it is necessary to release the "dead angle" system formed between the driving electric cylinder 506, the first articulated rod 502 and the second articulated rod 504, the adjusting hydraulic cylinder 507 works first to control the end of the driving electric cylinder 506 away from the output end to move up and down, thereby releasing the horizontal state of the driving electric cylinder 506. At this time, the setting state of the driving electric cylinder 506 is converted from a horizontal state to an inclined state, and then the driving electric cylinder 506 works again to control the first articulated rod 502 to rotate, thereby releasing the mutually overlapping matching relationship of the central axis of the first articulated rod 502 and the central axis of the second articulated rod 504.

[0032] Specifically, the driving unit 5 of this scheme also includes a blocking plate 509, which is arranged at the bottom of the mobile platform 1, and along the forward direction of the truck, the blocking plate 509 is located in front of the first connecting block 501. When the central axis of the first hinged rod 502 and the central axis of the second hinged rod 504 coincide with each other, the side wall surface of the first hinged rod 502 and the side wall surface of the second hinged rod 504 are jointly arranged to be in contact with the end face of the blocking plate 509. Through such a setting, it can further ensure that the driving electric cylinder 506 controls the first hinged rod 502 and the second hinged rod 504 to rotate to a vertical state, thereby avoiding deviation in the rotation of the first hinged rod 502 and the second hinged rod 504.

[0033] It should be noted that in this solution, there is damping in the rotational coordination between the first hinged rod 502 and the second hinged rod 504 , that is, the driving electric cylinder 506 needs to exert a certain force to control the rotation of the first hinged rod 502 and the second hinged rod 504 .

[0034] Furthermore, the present solution also includes a pressure module and an angle monitoring module. The pressure module is arranged on the blocking plate 509 to measure the pressing force between the first articulated rod 502 and the blocking plate 509; and the angle monitoring module is arranged on the driving electric cylinder 506 to monitor the tilt angle of the driving electric cylinder 506; through such a setting, when the pressure module monitors the value, it means that the first articulated rod 502 and the blocking plate 509 are set to fit each other, thereby realizing that the first articulated rod 502 is in a vertical state at this time; and the setting of the angle monitoring module is used to determine the tilt angle of the driving electric cylinder 506, and determine whether the driving electric cylinder 506 and the first articulated rod 502 and the second articulated rod 504 together form a "dead angle" system.

[0035] It is worth emphasizing that this solution cannot determine the rotation of the first hinged rod 502 and the second hinged rod 504, as well as the tilt angle state of the driving electric cylinder 506, by driving the electric cylinder 506 and adjusting the extension and contraction of the hydraulic cylinder 507. This is because the structural effect of the sliding block 505 being able to adaptively slide in the sliding groove 5021 makes it impossible to determine the position of the sliding block 505.

[0036] In addition, the adjusting slider 508 of the present invention is provided with an adjusting slot 5083, and the adjusting slot 5083 is arranged horizontally. The hinged end between the driving electric cylinder 506 and the adjusting slider 508 can be slidably arranged in the adjusting slot 5083 along the axial direction of the adjusting slot 5083. The adjusting slot 5083 is defined here as including a first space 5081 and a second space 5082. The first space 5081 is located in the end of the adjusting slot 5083 close to the first hinge rod 502, and the second space 5082 is located in the end of the adjusting slot 5083 away from the first hinge rod 502, and the part of the driving electric cylinder 506 sliding in the adjusting slot 5083 is defined as the hinged end of the driving electric cylinder 506; the purpose of setting the adjusting slot 5083 is to adjust the inclination angle of the driving electric cylinder 506. When the driving cylinder 506 completes the rotation of the first hinge rod 502 02's rotation is controlled, due to the influence of the interaction force, the hinged end of the driving electric cylinder 506 is located in the second space 5082, and then the driving electric cylinder 506 controls the output end to retract. Since there is damping in the rotation coordination between the first hinged rod 502 and the second hinged rod 504, it is actually the hinged end of the driving electric cylinder 506 that moves. After the hinged end of the driving electric cylinder 506 moves from the second space 5082 to the first space 5081, the driving electric cylinder 506 is controlled to stop working; then the adjusting slider 508 starts to work, controlling its output end to move, so that the driving electric cylinder 506 is transformed from a tilted state to a horizontal state. After the driving electric cylinder 506 is transformed into a horizontal state, the output end of the driving electric cylinder 506 is extended until the hinged end of the driving electric cylinder 506 moves to the second space 5082.
