Referring to fig. 1 to 11, according to the traffic cone displacement device 100 in the embodiment of the present invention, the traffic cone displacement device 100 includes a fixed frame 20, a moving frame 30, a gripping assembly 60, a first driving assembly 70 and a second driving assembly 80, the moving frame 30 is provided to the fixed frame 20 and is movable in a front-rear direction, the gripping assembly 60 is provided to the moving frame 30 and is movable in an up-down direction, the first driving assembly 70 is used for driving the moving frame 30 to move forward and backward, the second driving assembly 80 is used for driving the gripping assembly 60 to move up and down, wherein at least one of the first driving assembly 70 and the second driving assembly 80 includes a telescopic part and a driving part for driving the telescopic part to be telescopic; the fixed end of the telescopic part of the first driving assembly 70 is connected with the fixed frame 20, and the driving end is connected with the movable frame 30; the fixed end of the telescopic part of the second driving assembly 80 is connected with the movable frame 30, and the driving end is connected with the clamping assembly 60; thus, the operation efficiency of the traffic cone can be improved.

Specifically, the first driving assembly 70 is in transmission connection with the fixed frame 20 and the movable frame 30 respectively, so as to drive the movable frame 30 to move relative to the fixed frame 20 in the front-rear direction, and the second driving assembly 80 is in transmission connection with the movable frame 30 and the clamping assembly 60 respectively, so as to drive the clamping assembly 60 to move relative to the movable frame 30 in the up-down direction, and thus the clamping assembly 60 can perform compound movement relative to the fixed frame 20 under the driving action of the first driving assembly 70 and the second driving assembly 80, and can shift a traffic cone, thereby improving the efficiency of traffic cone retraction operation.

In addition, the first driving assembly 70 may include a telescopic portion and a driving portion, in the first driving assembly 70, the driving portion is in transmission connection with the telescopic portion, and the fixed end and the driving end of the telescopic portion may be respectively connected with two structural members, and the telescopic portion may be driven by the driving portion to implement telescopic motion, so as to drive the two structural members to perform relative motion, and in practice, since the transmission distance of the driving portion is limited, the driving stroke may be improved by using the telescopic portion as a transmission medium, so as to improve the working efficiency.

Likewise, the second driving assembly 80 may include a telescopic portion and a driving portion, in the second driving assembly 80, the driving portion is in transmission connection with the telescopic portion, and the fixed end and the driving end of the telescopic portion may be respectively connected with two structural members, and the telescopic portion may be driven by the driving portion to implement telescopic motion, so as to drive the two structural members to perform relative motion, and in practice, since the transmission distance of the driving portion is limited, the driving stroke may be improved by using the telescopic portion as a transmission medium, so as to improve the working efficiency.

Therefore, according to the traffic cone displacement device 100 in the embodiment of the invention, the traffic cone can be automatically displaced, the retraction operation of the traffic cone is facilitated, the operation efficiency is improved, and the safety of operators can be ensured.

Further, in some embodiments of the present invention, the telescoping portion is configured to drive the driving end of the telescoping portion at a rate of not less than 0 meters per second and not more than 0.4 meters per second relative to the fixed end to reduce the impact generated by the traffic cone displacement device 100, thereby improving the stability of the traffic cone displacement device 100.

Taking the first driving assembly 70 as an example: in operation, the first driving assembly 70 can drive the movable frame 30 to move relative to the fixed frame 20 along the front-back direction, and in this process, the traffic cone displacement device 100 is impacted due to excessive speed change, so the driving part can control the speed of the driving end of the telescopic part, so that the speed of the driving end of the telescopic part relative to the fixed end is in a range of not less than 0 m/s and not more than 0.4 m/s, and the stability of the traffic cone displacement device 100 is improved.

Referring to fig. 1 to 11, in some embodiments of the present invention, the telescopic part includes a scissor type telescopic structure, a driving rate of the driving part is inversely related to a transmission ratio of the telescopic part, and the transmission ratio of the telescopic part is a ratio of a telescopic rate of the telescopic part to a driving rate of the driving part; by this arrangement, the impact generated by the traffic cone displacement device 100 can be reduced, thereby improving the stability of the traffic cone displacement device 100.

In detail, the telescopic part is a scissor type telescopic structure, and the scissor type telescopic structure has a stroke amplifying function; when the telescopic part is extended at a predetermined driving rate, in other words, when the driving part drives the telescopic part to extend, the telescopic speed of the telescopic part is gradually increased, so that the traffic cone displacement device 100 is easily impacted; therefore, the driving rate of the driving part and the transmission ratio of the telescopic part can be inversely related, so that the driving rate of the driving part can be controlled to gradually decrease by the controller during extension, and the telescopic rate of the telescopic part can be reduced while the transmission ratio of the telescopic part is gradually increased, so that the telescopic rate of the telescopic part is maintained within a predetermined range, that is, the telescopic rate can be not less than 0 m/s and not more than 0.4 m/s, thereby improving the operation stability of the traffic cone displacement device 100.

Similarly, when the driving speed of the driving end of the telescopic part is gradually reduced when the driving part is driving the telescopic part to be shortened at a predetermined driving speed, in other words, the transmission ratio of the scissor type telescopic structure is gradually reduced, so that the traffic cone shifting device 100 is easily impacted; therefore, the driving rate of the driving part and the transmission ratio of the telescopic part can be inversely related, so that when the driving part is shortened, the telescopic rate of the driving part can be controlled to be gradually increased by the controller, and the telescopic rate of the telescopic part can be reduced while the transmission ratio of the telescopic part is gradually reduced, so that the telescopic rate of the telescopic part is maintained within a preset range, namely, the telescopic rate can be not less than 0 meter per second and not more than 0.4 meter per second, thereby improving the operation stability of the traffic cone displacement device 100.

In some embodiments of the invention, the drive portion may include a hydraulic drive member and a proportional valve coupled to the hydraulic drive member for controlling the amount of oil to the hydraulic drive member, the length of the opening telescoping portion of the proportional valve being inversely related. So as to reduce the impact generated by the traffic cone displacement device 100 and improve the stability of the traffic cone retraction operation.

Specifically, in the traffic cone displacement device 100, a controller may be provided that controls the opening degree of the proportional valve by inputting current to the proportional valve; generally, the larger the current input to the proportional valve by the controller, the larger the opening of the proportional valve; in other words, the controller may increase the current input to the proportional valve to increase the opening degree of the proportional valve, thereby causing more oil to flow to the hydraulic driver to control the driving rate of the hydraulic driver; thus, in combination with the foregoing embodiments, the current input to the proportional valve may be gradually reduced when the expansion portion is extended, or the current input to the proportional valve may be gradually increased when the expansion portion is contracted, so that the expansion rate of the expansion portion is maintained within a predetermined range, thereby improving the operation stability of the traffic cone displacement device 100.

Of course, the magnitude of the current input to the proportional valve by the controller may be inversely related to the opening degree of the proportional valve, that is, the current input to the proportional valve may be increased to decrease the opening degree of the proportional valve, and the aforementioned driving speed of the hydraulic driving member may also be achieved, so that the expansion and contraction speed of the expansion and contraction portion may be maintained within a predetermined range.

In addition, one end of the driving part of the first driving assembly 70 may be rotatably connected with one of the fixed frame 20 and the movable frame 30, and the other end is rotatably connected with the telescopic part of the first driving assembly 70 for hydraulically driving the telescopic part to be telescopic; one end of the driving part of the second driving assembly 80 can be rotatably connected with one of the movable frame 30 and the clamping assembly 60, and the other end of the driving part of the second driving assembly 80 is rotatably connected with the telescopic part of the second driving assembly; in this manner, the driving action of the first driving assembly 70 and the second driving assembly 80 can be achieved.

In the first driving assembly 70, the driving part is respectively connected with the fixed frame 20 and the telescopic part in a rotating way, and the driving part is a hydraulic driving part which can be in transmission with the telescopic part so as to indirectly drive the movable frame 30 to move relative to the fixed frame 20 along the front-back direction through the telescopic part; in the second driving assembly 80, a driving part is respectively connected with the moving frame 30 and the telescopic part in a rotating way, the driving part is a hydraulic driving piece, and the hydraulic driving frame can be in transmission with the telescopic part, so that the clamping assembly 60 is indirectly driven to move relative to the moving frame 30 along the up-down direction through the telescopic part.

Referring to fig. 1 to 11, in some embodiments of the present invention, the telescopic part is a scissor type telescopic structure, the driving part is constructed in a linear driving structure, and a moving rate of a driving shaft of the driving part is inversely related to a length of the telescopic part; thus, the impact applied to the traffic cone displacement device 100 can be reduced, and the stability of the traffic cone retraction operation can be improved.

In detail, the scissor type telescopic structure has a stroke amplifying effect, namely the transmission ratio of the telescopic part is gradually increased when the telescopic part is extended, and the transmission ratio is gradually reduced when the telescopic part is shortened, in other words, the transmission ratio of the telescopic part is positively related to the length of the telescopic part; when the driving shaft of the driving part drives the telescopic part to extend at a predetermined moving speed, the telescopic speed of the telescopic part gradually increases, and the traffic cone displacement device 100 is easily impacted; therefore, the moving speed of the driving shaft of the driving part and the length of the telescopic part can be inversely related, so that the moving speed of the driving shaft of the driving part can be controlled to gradually decrease when the driving part is extended, and the telescopic speed of the telescopic part is maintained in a preset range while the transmission ratio of the telescopic part is gradually increased, namely, the telescopic speed can be not less than 0 m/s and not more than 0.4 m/s, thereby improving the operation stability of the traffic cone shifting device 100.

Similarly, when the telescopic portion is shortened, the moving speed of the driving shaft of the driving portion may be gradually increased so as to make the telescopic speed position of the telescopic portion within a predetermined range while the transmission ratio of the telescopic portion is gradually reduced, thereby improving the operation stability of the traffic cone displacement device 100.

Further, referring to fig. 2, 4-7, 11, in some embodiments of the present invention, one of the first link 111 and the second link 112 of the first end bar set 11a is slidably and rotatably connected to the first structural member 21 through a mounting seat, and the other link is rotatably connected to the first structural member 21 through a mounting seat; one of the first link 111 and the second link 112 of the second end bar set 11b is slidably and rotatably connected to the second structural member 31 through a mount, and the other link is rotatably connected to the second structural member 31 through a mount; thus, the transmission reliability of the traffic cone displacement device 100 can be improved, and the efficiency of the traffic cone retraction operation can be improved.

Specifically, the two links of the first end bar set 11a are respectively connected with the first structural member 21, and the two links of the second end bar set 11b are respectively connected with the second structural member 31, so as to increase the connection position between the telescopic part and the structural member, thereby improving the reliability of transmission. And a plurality of pole groups 11 are connected to form a scissor type telescopic structure, the scissor type telescopic structure can convert the rotary motion of the connecting rods into linear motion along a preset direction, so that two connecting rods of the first end pole group 11a are rotationally connected with the first structural member 21, two connecting rods of the second end pole group 11b are rotationally connected with the second structural member 31, and the second structural member 31 can be driven to move along the preset direction relative to the first structural member 21 when the telescopic part stretches and contracts, thereby being convenient for the retraction operation of the traffic cone.

In addition, in order to ensure that the second structural member 31 moves linearly in a predetermined direction relative to the first structural member 21 during the assembly of the telescopic portion, the connecting rod of the first end rod group 11a and the connecting rod of the second end rod group 11b need to be corresponding to each other when being connected to the first structural member 21 and the second structural member 31; for example, in the first end bar assembly 11a, the first link 111 is slidably and rotatably connected to the first structural member 21 through the first mounting seat 42, and the second link 112 is rotatably connected to the first structural member 21 through the second mounting seat 45, then in the second end bar assembly 11b, the link corresponding to the first link 111 is slidably and rotatably connected to the second structural member 31 through the mounting seat, and the link corresponding to the second link 112 is rotatably connected to the second structural member 31 through the mounting seat, so that the second structural member 31 can linearly move in a predetermined direction with respect to the first structural member 21 when the telescopic portion is driven. Conversely, if the links in the first end rod set 11a and the second end rod set 11b do not correspond, when the second structural member 31 moves relative to the first structural member 21, the second structural member 31 will vertically deviate along the predetermined direction, thereby affecting the normal operation of the traffic cone retraction.

Step S100, determining state parameters of the telescopic part, wherein the state parameters of the telescopic part comprise at least one of length, telescopic speed, telescopic acceleration or operation duration of the telescopic part;

The sensor can be set to detect the state parameter of the telescopic part, for example, a displacement sensor can be set, the telescopic part is driven by setting a preset driving speed for the driving part, the length of the telescopic part is detected by the displacement sensor to obtain the length change value of the telescopic part in unit time, and then the transmission ratio of the telescopic part can be calculated by the length change value of the telescopic part in unit time and the length change value of the driving part in unit time; for another example, a speed sensor may be provided, the telescopic portion is driven by setting a predetermined driving speed for the driving portion, the telescopic speed of the telescopic portion is detected by the speed sensor, and then the transmission ratio of the telescopic portion may be calculated by the ratio of the telescopic speed to the driving speed; for another example, an acceleration sensor may be provided, the driving portion is provided with a predetermined driving speed to drive the telescopic portion, the acceleration of the telescopic portion is detected by the acceleration sensor, so as to obtain a telescopic speed corresponding to the acceleration, and then a transmission ratio of the telescopic portion is calculated by a ratio of the telescopic speed to the driving speed.

In practice, at least one of the foregoing examples may be employed to facilitate a better implementation of determining the status parameters of the telescoping portion.

Step S200, determining the driving speed of the driving part, wherein the driving speed is determined according to the state parameters of the telescopic part;

Specifically, a predetermined driving rate can be set for the driving part, so that the driving part can be driven at a constant driving rate, the driving stroke of the driving part is divided into twenty sections, and when the driving part drives the telescopic part to stretch, the length change value of the telescopic part corresponding to the driving stroke of the driving part can be measured and calculated, so that the transmission ratio of the telescopic part corresponding to each section of driving stroke is calculated; in other words, the transmission ratio may be a ratio of a telescopic speed of the telescopic portion to a driving speed of the driving portion.

In some embodiments of the invention, the state parameter of the telescoping portion includes a telescoping rate of the telescoping portion, the drive rate of the drive portion being inversely related to the telescoping rate of the telescoping portion; specifically, a speed sensor may be provided, by setting a predetermined driving speed for the driving part, so that the driving part may drive the telescopic part at a constant driving speed, then the driving stroke of the driving part may be divided into twenty sections, the telescopic speed of each section of driving stroke of the telescopic part corresponding to the driving part may be detected by the speed sensor, and then the transmission ratio of the telescopic part corresponding to each section of driving stroke may be calculated from the ratio of the telescopic speed of the telescopic part to the predetermined driving speed of the driving part, and since the larger the transmission ratio of the telescopic part is, the larger the telescopic speed of the telescopic part is, the driving speed of the driving part may be reduced while the transmission ratio of the telescopic part is increased, and thus the telescopic speed of the telescopic part may be maintained within the predetermined range to reduce the impact to which the traffic cone shifting device 100 is subjected.

In some embodiments of the present invention, the state parameter of the telescopic part includes a telescopic acceleration of the telescopic part, and the driving speed of the driving part is inversely related to the telescopic acceleration of the telescopic part; specifically, an acceleration sensor may be provided, by providing the driving portion with a predetermined driving rate, so that the driving portion may drive the telescopic portion at a constant driving rate, then the driving stroke of the driving portion may be divided into twenty sections, the acceleration of each section of driving stroke of the telescopic portion corresponding to the driving portion may be detected by the acceleration sensor, then the ratio of the average telescopic rate of the telescopic portion to the predetermined driving rate of the driving portion may be calculated by conversion, and the transmission ratio of the telescopic portion corresponding to each section of driving stroke may be calculated.

In some embodiments of the present invention, the status parameter of the telescoping portion includes a length of time of operation of the telescoping portion, and determining the drive rate of the drive portion includes: the operation mode of the telescopic part is determined, and the operation mode comprises an extension mode and a contraction mode. Wherein in the extended mode, the drive rate is inversely related to the length of the job; in the shrink mode, the drive rate is positively correlated with the duration of the job; to reduce the impact to which the traffic cone displacement device 100 is subjected.

Specifically, by setting a predetermined driving rate for the driving portion, the driving portion may drive the telescopic portion at a constant driving rate, then the driving stroke of the driving portion may be divided into twenty sections, the telescopic rate of each section of driving stroke of the telescopic portion corresponding to the driving portion may be detected and calculated by the aforementioned displacement sensor, speed sensor and acceleration sensor, and then the transmission ratio of the telescopic portion corresponding to each section of driving stroke may be calculated from the telescopic rate of the telescopic portion and the driving rate of the driving portion.

In the calculation of the gear ratio, the driving part drives the telescopic part at a constant driving speed, so that the operation time length is related to the gear ratio of the telescopic part; in the extension mode, the operation time length is positively correlated with the transmission ratio of the telescopic part, and in the contraction mode, the operation time length is inversely correlated with the transmission ratio of the telescopic part, so that in order to maintain the telescopic speed of the telescopic part within a predetermined range, in the extension mode, the driving speed of the driving part is reduced while the operation time length is increased; in the contraction mode, the driving rate of the driving portion is increased while the operation time period is increased, so that the expansion and contraction rate of the expansion and contraction portion can be maintained within a predetermined range to reduce the impact to which the traffic cone displacement device 100 is subjected.

Specifically, in the traffic cone displacement device 100, a controller may be provided, which may control the amount of oil flowing to the hydraulic driver by controlling the magnitude of the current input to the proportional valve; in general, the magnitude of the current input by the controller is positively correlated with the opening degree of the proportional valve, and since the telescopic part includes a scissor type telescopic structure having a stroke amplifying function, in other words, when the telescopic part stretches, the telescopic rate of the telescopic part is suddenly changed, so that the traffic cone displacement device 100 is impacted, therefore, when the telescopic part stretches during the traffic cone winding and unwinding operation, the controller can reduce the current input to the proportional valve, and when the telescopic part stretches, the controller can increase the current input to the proportional valve, so that the telescopic rate of the telescopic part is maintained within a predetermined range, thereby avoiding the impact of the traffic cone displacement device 100.
