[0037] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0038] Referring to Figure 1 It shows a structural schematic diagram of a telescopic belt conveyor control system provided by an embodiment of the present application, which comprises a telescopic belt conveyor 10 and a control device 20. The telescopic belt conveyor 10 comprises a base 11, three transmission mechanisms 121, 122 and 123 with volumes decreasing in turn and connected in turn, a first telescopic rod 13, a support 14 and a distance sensor 15 arranged at the end of the second transmission mechanism 122 with the smallest volume. The distance sensor 15 is used to detect the distance between the end of the second transmission mechanism 122 and the support surface. The first transmission mechanism 121 with the largest volume is fixedly arranged on the base 11. The side of the transmission mechanism away from the base 11 is the transmission surface, which can be in the form of a belt conveyor. The fixed end of the first telescopic rod 13 is connected with the base 11, and the telescopic end of the first telescopic rod 13 is connected with the first transmission mechanism 121.

[0039] In one case, the control device 20 can be a device integrated in the telescopic belt conveyor 10, and the control device 20 is used to control the working of each component of the telescopic belt conveyor 10. In another case, the control device 20 can also be a remote control device, and the control device 20 can be in communication connection with the telescopic belt conveyor 10 and control the working of each component of the telescopic belt conveyor 10 from a remote place.

[0040] Specifically, Figure 1The main body of the telescopic belt conveyor 10 is composed of the first transmission mechanism 121, the third transmission mechanism 123 and the second transmission mechanism 122 in order of decreasing volume, the first transmission mechanism 121 has the largest volume, the first transmission mechanism 121 is fixedly arranged on the base 11, the base 11 can be arranged on an assembly plane, the third transmission mechanism 123 has the second largest volume, the third transmission mechanism 123 can be nested in the first transmission mechanism 121 and can be controlled to extend out of or retract into the first transmission mechanism 121, the second transmission mechanism 122 has the smallest volume, the second transmission mechanism 122 can be nested in the third transmission mechanism 123 and can be controlled to extend out of or retract into the third transmission mechanism 123, through the telescopic transmission mechanism, the telescopic belt conveyor 10 can realize the increase or decrease of the length of the transmission surface, thereby meeting the requirement of the transmission distance during logistics transportation.

[0041] It should be noted that the number of transmission mechanisms is not limited in the embodiments of the present application, and the number of transmission mechanisms can be increased or decreased based on different actual requirements, in addition, the support 14 and the distance sensor 15 can also be arranged on any one of the other transmission mechanisms except the first transmission mechanism 121, and the support 14 and the distance sensor 15 can also be arranged at a position other than the end of the transmission mechanism, for example, referring to Figure 2 which shows a structure side view of a telescopic belt conveyor provided by the embodiments of the present application, wherein the support 14 and the distance sensor 15 can be arranged on the third transmission mechanism 123, and the support 14 and the distance sensor 15 are arranged at a position other than the end of the third transmission mechanism 123, in this case, through the support of the third transmission mechanism 123 by the support 14, the support force can still be transmitted to the second transmission mechanism 122, which can be applied to the scenario that the support cannot be installed at the end of the second transmission mechanism 122 due to structural limitations, thereby improving the applicable scenarios of the telescopic belt conveyor.

[0042] Further, referring to Figure 1 , the first end of the first transmission mechanism 121 away from the other transmission mechanisms is provided with a rotating mechanism 16 between the base 11, the control device 20 can make the first end of the first transmission mechanism 121 rotate around the rotating mechanism 16 through the extension of the first telescopic rod 13, thereby lifting the second end opposite to the first transmission mechanism 121, and the whole transmission surface is lifted; the control device 20 can make the first end of the first transmission mechanism 121 rotate around the rotating mechanism 16 through the retraction of the first telescopic rod 13, thereby lowering the second end opposite to the first transmission mechanism 121, and the whole transmission surface is lowered; through the extension and retraction of the first telescopic rod 13, the telescopic belt conveyor 10 can realize the change of the slope of the transmission surface, thereby meeting the requirement of the slope of the transmission surface during logistics transportation.

[0043] On the basis of realizing the control requirements of the transmission surface slope and length, in order to further improve the stability of the transmission mechanism of the telescopic belt conveyor when it is stretched out with a large length, the embodiment of the present application can set a support 14 on the second transmission mechanism 122, which is used to contact the support surface below when the second transmission mechanism 122 is stretched out, thereby providing sufficient support force for the second transmission mechanism 122.

[0044] It should be noted that in one case, the support surface facing the second transmission mechanism 122 and the assembly plane on which the base 11 is installed can be the same plane, such as the ground; in another case, the support surface facing the second transmission mechanism 122 and the assembly plane on which the base 11 is installed can be different planes, such as the assembly plane being the ground and the support surface being the bottom surface of the cargo box of the vehicle parked on the ground.

[0045] Reference Figure 1 Preferably, the second transmission mechanism 122 is the transmission mechanism farthest from the first transmission mechanism 121, and the support 14 and the distance sensor 15 are respectively arranged at the end of the second transmission mechanism 122 away from the first transmission mechanism 121, so that the specific effect of arranging the support 14 at the end of the second transmission mechanism 122 includes:

[0046] 1. When the second transmission mechanism 122 is stretched out with a large length, if there is heavy cargo on the transmission surface of the second transmission mechanism 122, the support of the support 14 can prevent the first end of the second transmission mechanism 122 away from other transmission mechanisms from being raised upward, thereby improving the upper limit of the weight of the cargo that the second transmission mechanism 122 can carry.

[0047] 2. In related technologies, in order to meet the stability of the second transmission mechanism 122 when carrying cargo, the base 11 needs to be firmly fixed on the assembly plane, which has a high requirement on the assembly plane, while in the embodiment of the present application, the support of the second transmission mechanism 122 by the support 14 can cancel the high-strength fixation of the base 11 and the assembly plane, thereby enabling the telescopic belt conveyor to be installed on various assembly planes and improving the application range.

[0048] 3. The support of the second transmission mechanism 122 by the support 14 improves the stability of the second transmission mechanism 122, thereby enabling the second transmission mechanism 122 to be installed with devices such as mechanical arms and palletizers that have high requirements on the stability of the installation position, thereby improving the automation degree of the telescopic belt conveyor.

[0049] 4. By supporting the second transmission mechanism 122 with the support member 14, the design of the first transmission mechanism 121 no longer needs to pursue high-strength and heavy structures and materials. This allows the design of the first transmission mechanism 121 to develop in the direction of lightweight and low cost, reducing equipment costs. In addition, the power requirements of the telescopic belt conveyor are reduced based on the lightweight design. In related technologies, telescopic belt conveyors require 380 volts of electricity for driving, while the lightweight telescopic belt conveyor of this application embodiment can be driven by 220 volts of electricity, reducing electricity costs.

[0050] Since telescopic belt conveyors need to continuously adjust the length and slope of the transmission surface according to actual needs in the actual working environment, in order to further improve the automation level of the telescopic belt conveyor, this embodiment of the application can be equipped with a distance sensor 15 for detecting the distance between the second transmission mechanism 122 and the support surface, so that the control device 20 can automatically adjust the extension and retraction state of the first telescopic rod 13 according to the detection value of the distance sensor 15. For example, when the control device 20 determines, based on the detection value of the distance sensor 15, that the distance between the second transmission mechanism 122 and the support surface is too large, causing the end of the support member 14 to be unable to contact the support surface, it can control the first telescopic rod 13 to retract, thereby reducing the height of the second transmission mechanism 122, so that the support member 14 can contact the support surface to form support.

[0051] Furthermore, in this embodiment of the application, the support member 14 can be selected as the second telescopic rod, so that the support member can be telescopic. In this case, the control device 20 can control the telescopic state of the first telescopic rod 13, the support member 14 and the transmission mechanism, so that the end of the support member 14 can effectively contact the support surface to form a support while meeting the requirements of the length and slope of the transmission surface.

[0052] For example, if the slope and length of the transmission surface already meet the actual requirements, and the distance between the second transmission mechanism 122 and the support surface is too large, causing the end of the support member 14 to be unable to contact the support surface, the control device 20 can control the support member 14 to extend and contact the support surface to form support, thus avoiding changes to the slope and length of the transmission surface.

[0053] To better describe the application scenarios of the telescopic belt conveyor control system of this application embodiment, several specific application scenarios of the telescopic belt conveyor control system are provided below:

[0054] In a logistics transportation scenario where a telescopic belt conveyor control system is applied, referring to Figure 3Fig. 6 shows a specific application scenario of the telescopic belt conveyor control system provided by the embodiments of the present application, in which the goods 30 on the platform of the logistics warehouse are required to be transmitted to the carriage of the freight car 42 through the telescopic belt conveyor, wherein the assembly plane of the base 11 of the telescopic belt conveyor can be the plane of the platform 41 of the logistics warehouse, the base 11 bears the first transmission mechanism 121, and the support plane faced by the support 14 arranged on the second transmission mechanism 122 is the plane of the carriage of the freight car 42. Assuming that the plane of the carriage of the freight car 42 is flush with the plane of the platform 41 of the logistics warehouse, in the case that the transmission mechanism is extended, the control device can control the first telescopic rod to be retracted according to the distance between the second transmission mechanism 122 and the plane of the carriage of the freight car 42 detected by the distance sensor, so that the support 14 is in contact with the plane of the carriage of the freight car 42 to form effective support for the second transmission mechanism 122. Specifically, in the case that the distance detected by the distance sensor is greater than the length of the support 14, the control device controls the first telescopic rod 13 to be retracted until the support 14 is in contact with the plane of the carriage of the freight car 42; in the case that the distance detected by the distance sensor is less than the length of the support 14, the control device controls the first telescopic rod 13 to be extended until the support 14 is in contact with the plane of the carriage of the freight car 42, and no action is taken if the distance detected by the distance sensor is equal to the length of the support 14.

[0055] In addition, the support 14 can also be selected as a second telescopic rod, so that the support is telescopic. In the case that the distance detected by the distance sensor is greater than the length of the support 14, the control device controls the support 14 to be extended to contact the plane of the carriage of the freight car 42; in the case that the distance detected by the distance sensor is less than the length of the support 14, the control device controls the support 14 to be retracted to contact the plane of the carriage of the freight car 42.

[0056] It should be noted that for the case that the distance detected by the distance sensor is less than the length of the support, the specific implementation can refer to the above description. Figure 4Fig. 6 shows a specific application scenario of another stretchable belt conveyor control system provided by the embodiments of the present application, wherein the distance sensor 15 is arranged on the side of the support 14 away from the first conveying mechanism 121. During the extension of the conveying mechanism, if the distance sensor 15 faces the plane of the carriage of the truck 42, and the support 14 is too long, the distance detected by the distance sensor 15 is less than the length of the support 14. At this time, the extension of the conveying mechanism can be stopped first, and the first telescopic rod 13 is controlled to extend to lift the conveying plane, or the support 14 is controlled to retract, and then the conveying mechanism is controlled to continue to extend to the target length. Finally, the first telescopic rod 13 or the support 14 is controlled to extend or retract until the distance detected by the distance sensor 15 is equal to the length of the support 14. At this time, the support 14 no longer interferes with the plane of the carriage of the truck 42 and can form effective support.

[0057] In another logistics transportation scenario in which the stretchable belt conveyor control system is applied, referring to Fig. 6, Figure 5 Fig. 6 shows a specific application scenario of another stretchable belt conveyor control system provided by the embodiments of the present application. In this scenario, the goods 30 on the ground of the logistics warehouse need to be conveyed to the carriage of the truck 42 by the stretchable belt conveyor. The assembly plane of the base 11 of the stretchable belt conveyor can be the ground of the logistics warehouse. The base 11 carries the first conveying mechanism 121, and the support surface faced by the support 14 arranged on the second conveying mechanism 122 is the plane of the carriage of the truck 42. Since there is a height difference between the support surface and the assembly plane, the conveying plane needs to be lifted to smoothly convey the goods.

[0058] Then the control device can control the first telescopic rod to extend to lift the conveying plane, and then control the conveying mechanism to extend. In the case of the extension of the conveying mechanism, the first telescopic rod 13 is further controlled to extend or retract according to the distance between the second conveying mechanism 122 and the plane of the carriage of the truck 42 detected by the distance sensor 15, so that the support 14 contacts the plane of the carriage of the truck 42 to form effective support for the second conveying mechanism 122.

[0059] It should be noted that, in Figure 5 Since the support 14 forms a vertical angle with the second conveying mechanism 122, when the support 14 contacts the plane of the carriage of the truck 42 to form support, the support 14 protrudes outward, which affects the normal work of the workers at the outlet of the second conveying mechanism 122. Therefore, referring to Fig. 7, Figure 6The embodiment of the present application can also be provided with a rotating mechanism 141 at the connection between the second conveying mechanism 122 and the support 14, so that the angle formed by the second conveying mechanism 122 and the support 14 can be adjusted through the rotating mechanism 141. During the process of supporting the support 14 to form a plane of the carriage of the truck 42, the support 14 can be adjusted to be perpendicular to the plane of the carriage of the truck 42, thereby avoiding the occupation of the support 14 to the delivery port position, and improving the delivery fluency.

[0060] In another logistics transportation scene applied by the telescopic belt conveyor control system, referring to Figure 7 which shows a specific application scene schematic diagram of another telescopic belt conveyor control system provided by the embodiment of the present application. Due to the effective support of the support 14 to the position of the second conveying mechanism 122, the stability of the position of the second conveying mechanism 122 is effectively improved, so that a load device with higher stability requirement can be installed at the position of the second conveying mechanism 122 to assist in the transportation of goods, Figure 7 The load device in the above can be a mechanical arm 50, which can assist in carrying heavy goods and improve the automation of transportation. In addition, in some other cases, the load device can also be a palletizer, which can realize the automatic stacking of goods.

[0061] In the embodiment of the present application, the support and the distance sensor can be provided on the second conveying mechanism of the telescopic belt conveyor except the first conveying mechanism, so that when the conveying mechanism of the telescopic belt conveyor is stretched out, the control device can control the first telescopic rod to stretch and retract according to the distance detected by the distance sensor, so that the end of the support away from the second conveying mechanism is in contact with the support surface, thereby forming effective support to the second conveying mechanism, avoiding the front section of the telescopic belt conveyor being suspended in the air after being stretched out, and improving the stability of the front section of the telescopic belt conveyor. On the basis of meeting the stability of the front section of the telescopic belt conveyor, the material selection and mechanism of the first conveying mechanism can be designed to be lightweight, thereby reducing the equipment cost.

[0062] Referring to Figure 1The embodiment of the present application provides a telescopic belt conveyor control system, which comprises a telescopic belt conveyor 10 and a control device 20; the telescopic belt conveyor 10 comprises a base 11, a plurality of transmission mechanisms 12 connected in sequence, a first telescopic rod 13, a support 14 and a distance sensor 15; a first transmission mechanism 121 in the plurality of transmission mechanisms 12 is fixedly arranged on the base 11, and two ends of the first telescopic rod 13 are connected with the base 11 and the first transmission mechanism 121 respectively; the support 14 and the distance sensor 15 are arranged on a second transmission mechanism 122 in the transmission mechanism other than the first transmission mechanism 121 respectively, and the distance sensor 15 is used for detecting the distance between the second transmission mechanism 122 and a support surface; the support surface is a plane faced by the side of the second transmission mechanism 122 facing the base 11; and the control device 20 is used for controlling the first telescopic rod 13 to be telescopic according to the distance detected by the distance sensor 15 when the transmission mechanism 12 is extended, so that the end of the support 14 away from the second transmission mechanism 122 is in contact with the support surface.

[0063] It should be noted that, in the structure shown in the figure, Figure 1 In the structure shown in the figure, the second transmission mechanism 122 can be the transmission mechanism farthest from the first transmission mechanism 121, and in other cases, it can be other transmission mechanisms other than the first transmission mechanism.

[0064] In the embodiment of the present application, after the support is arranged on the second transmission mechanism, the support can effectively support the second transmission mechanism and the transmission mechanisms nearby, and the reference Figure 8 The figure shows the structure side view of another telescopic belt conveyor provided by the embodiment of the present application, specifically, in the process that the telescopic belt conveyor transports goods 30, the goods 30 are distributed at various positions of the transmission surface, so that the gravity of the entire telescopic belt conveyor and the gravity of the goods 30 are both applied to the base 11 and the first telescopic rod 13, after the transmission mechanism of the telescopic belt conveyor is completely extended, due to the lever effect, the pressure borne by the first telescopic rod 13 is greater than 2 times the sum of the gravity of the telescopic belt conveyor and the gravity of the goods 30, and there is a strong stress at the connection position of the second transmission mechanism 122 and the third transmission mechanism 123, and after the support rod 14 of the second transmission mechanism 122 is in contact with the support surface to form effective support, the gravity of the telescopic belt conveyor and the gravity of the goods 30 can be evenly applied to the positions of the base 11, the first telescopic rod 13 and the support rod 14 respectively, thereby reducing the pressure borne by the first telescopic rod 13 and reducing the influence of the stress at the connection position of the second transmission mechanism 122 and the third transmission mechanism 123.

[0065] In conclusion, in the embodiment of the present application, the support and the distance sensor are arranged on the second conveying mechanism of the telescopic belt conveyor other than the first conveying mechanism, so that when the conveying mechanism of the telescopic belt conveyor is extended, the control device can control the first telescopic rod to extend or retract according to the distance detected by the distance sensor, so that the end of the support away from the second conveying mechanism is in contact with the support surface, thereby forming effective support for the second conveying mechanism, avoiding the front section of the telescopic belt conveyor being suspended in the air after being extended, and improving the stability of the front section of the telescopic belt conveyor. On the basis of meeting the stability of the front section of the telescopic belt conveyor, the first conveying mechanism can be designed to be lightweight, thereby reducing the cost of the equipment.

[0066] Optionally, the support has a fixed length; and the control device is specifically used for: in a case where the distance detected by the distance sensor is greater than the length of the support, controlling the first telescopic rod to retract until the distance detected by the distance sensor is equal to the length of the support; and in a case where the distance detected by the distance sensor is less than the length of the support, controlling the first telescopic rod to extend until the distance detected by the distance sensor is equal to the length of the support.

[0067] In the embodiment of the present application, the distance detected by the distance sensor is used to adjust the extension and retraction of the first telescopic rod, and the distance between the second conveying mechanism and the conveying surface can be adjusted to match the length of the support by changing the slope of the conveying surface, so that the support can contact the conveying surface to form effective support, thereby improving the stability of the front section of the telescopic belt conveyor.

[0068] Optionally, in a case where the distance detected by the distance sensor is greater than the length of the support, the control device is further used for: controlling the conveying mechanism to extend or retract, and stopping in a case where the total length of the conveying mechanism reaches the target total length; and controlling the first telescopic rod to retract until the distance detected by the distance sensor is equal to the length of the support.

[0069] In the embodiment of the present application, when the conveying mechanism is extended, if the control device determines that the distance detected by the distance sensor is greater than the length of the support, it can be considered that the current second conveying mechanism is in a state of being suspended in the air from the support surface. In order to further improve the stability of the equipment through effective support of the support on the basis of meeting the target total length of the conveying surface, the control device can first control the conveying mechanism to extend or retract, and stop in a case where the total length of the conveying mechanism reaches the target total length. At this time, the total length of the conveying mechanism reaches the target total length for conveniently conveying goods. Then, the control device can control the first telescopic rod to retract, thereby reducing the slope of the conveying surface, until the distance detected by the distance sensor is equal to the length of the support. At this time, the support is in contact with the support surface to form effective support.

[0070] Optionally, the support member comprises a second telescopic rod; a fixed end of the second telescopic rod is connected with the second conveying mechanism, and a telescopic end of the second telescopic rod faces the support surface; the control device is specifically used for: in a case where it is determined that the distance detected by the distance sensor is greater than a current length of the second telescopic rod, controlling the second telescopic rod to extend until the distance detected by the distance sensor is equal to the length of the second telescopic rod; in a case where it is determined that the distance detected by the distance sensor is less than the current length of the second telescopic rod, controlling the second telescopic rod to retract until the distance detected by the distance sensor is equal to the length of the second telescopic rod.

[0071] In the embodiment of the application, the support member can also be selected as a second telescopic rod, so that the support member is telescopic; in a case where it is determined that the distance detected by the distance sensor is greater than the length of the second telescopic rod, the control device controls the second telescopic rod to extend, so that the second telescopic rod is in contact with the support surface; in a case where it is determined that the distance detected by the distance sensor is less than the length of the second telescopic rod, the control device controls the second telescopic rod to retract, so that the second telescopic rod is in contact with the support surface; the embodiment of the application can adjust the second telescopic rod to a state capable of contacting the support surface to form effective support through the telescoping of the second telescopic rod without changing the slope and length of the conveying surface, and can meet the support requirement in some scenes where the slope and length of the conveying surface cannot be changed.

[0072] Optionally, the support member comprises a second telescopic rod; a fixed end of the second telescopic rod is connected with the second conveying mechanism, and a telescopic end of the second telescopic rod faces the support surface; the distance sensor is arranged on a side of the second telescopic rod away from the first conveying mechanism.

[0073] In the embodiment of the application, on the basis of the support member being selected as a second telescopic rod, the embodiment of the application can comprehensively control the telescoping of the first telescopic rod, the second telescopic rod and the conveying mechanism through the control device in combination with the slope and length requirement of the conveying surface and the support requirement of the support member in a specific conveying process, so as to meet the above requirement in an actual process.

[0075] In the first case, the control device determines a first length required by the second telescopic rod according to the target slope and the target total length of the conveying mechanism in a case where the target slope and the target total length of the conveying mechanism are acquired, and controls the second telescopic rod to elongate or retract to the first length.

[0076] In this case, the specific conveying process has requirements for the slope and the total length of the conveying surface, and the control device can determine the extension amount of the first telescopic rod 13 according to the target slope a, control the first telescopic rod 13 to extend or retract according to the extension amount so that the slope of the conveying surface reaches the target slope a, and then control the conveying mechanism to extend to the total length reaching the target total length L1. Finally, the first length L2 required by the second telescopic rod 14 to form effective support can be calculated through the target total length L1 and the target slope a, and the second telescopic rod 14 is controlled to extend or retract to the first length L2, so as to realize the comprehensive control of the control device on the extension of the first telescopic rod, the second telescopic rod and the conveying mechanism on the basis of meeting the requirements of the slope of the conveying surface, the total length and the effective support of the support.

[0077] In the second case, the control device obtains the target length of the second telescopic rod and the target total length of the conveying mechanism, determines the second length required by the first telescopic rod according to the target length and the target total length, and controls the first telescopic rod to extend or retract to the second length.

[0078] In this case, the specific conveying process has requirements for the total length of the conveying surface and the height of the outfeed opening of the telescopic belt conveyor, and the control device can determine the target slope a required by the conveying surface according to the target length L2 (the height of the outfeed opening) of the second telescopic rod and the target length L1 of the conveying surface, and determine the extension amount of the first telescopic rod 13 according to the target slope a. The first telescopic rod 13 is controlled to extend or retract according to the extension amount so that the slope of the conveying surface reaches the target slope a, and the second telescopic rod 14 forms effective support through the target length L2, so as to realize the comprehensive control of the control device on the extension of the first telescopic rod, the second telescopic rod and the conveying mechanism on the basis of meeting the requirements of the slope of the conveying surface, the total length and the effective support of the support.

[0079] In the third case, the control device obtains the target length of the second telescopic rod and the target slope of the conveying mechanism, determines the third length required by the conveying mechanism according to the target length and the target slope, and controls the conveying mechanism to extend or retract to the third length.

[0080] In this case, the specific transmission process has the requirement of the slope of the transmission surface and the height of the outfeed opening of the telescopic belt conveyor, the control device of the embodiment of the application can determine the telescopic amount of the first telescopic rod 13 according to the target slope a, and control the first telescopic rod 13 to telescope so that the slope of the transmission surface reaches the target slope a, and then determine the target length L1 of the transmission surface according to the target length L2 (the height of the outfeed opening) of the second telescopic rod and the target slope a of the transmission surface, and control the telescopic transmission mechanism to telescope so that the length of the transmission surface reaches the target length L1, and the second telescopic rod 14 forms effective support through the target length L2, so as to realize the comprehensive control of the control device on the telescoping of the first telescopic rod, the second telescopic rod and the telescopic transmission mechanism on the basis of meeting the requirements of the slope of the transmission surface, the total length and the effective support of the support.

[0081] Optionally, referring to Figure 1 , the second transmission mechanism 122 is the transmission mechanism farthest from the first transmission mechanism 121, the support 14 and the distance sensor 15 are arranged at the end of the second transmission mechanism 122 away from the first transmission mechanism 121, and the distance sensor 15 is arranged on the side of the support 14 away from the first transmission mechanism 121.

[0082] In the embodiment of the application, preferably, since the second transmission mechanism 122 farthest from the first transmission mechanism 121 is the transmission mechanism most affected by stress when the transmission mechanism is elongated to the longest, the support 14 and the distance sensor 15 are arranged at the end of the second transmission mechanism 122 away from the first transmission mechanism 121, which can further reduce the influence of the stress received by the second transmission mechanism 122 and further improve the stability of the second transmission mechanism 122. In addition, the effect of arranging the distance sensor 15 on the side of the support 14 away from the first transmission mechanism 121 has been explained in the above Figure 4 embodiment, which will not be repeated here.

[0083] Optionally, referring to Figure 1 , the first end of the first transmission mechanism 121 away from other transmission mechanisms is provided with a rotating mechanism 16 between the first end and the base, the first telescopic rod 13 is connected to the second end of the first transmission mechanism 121 close to other transmission mechanisms, and the first end of the first transmission mechanism 121 rotates around the rotating mechanism 16 in the case of extension or retraction of the first telescopic rod 13.

[0084] The rotating mechanism 16 can include rotating shaft mechanisms arranged on opposite sides of the first transmission mechanism 121 respectively to achieve the purpose of rotation of the first end of the first transmission mechanism 121.

[0085] Optionally, referring to Figure 10The supporting roller 142 is arranged at one end of the supporting member 14 away from the second conveying mechanism 122.

[0086] In the embodiment of the present application, the supporting roller 142 is arranged at one end of the supporting member 14 away from the second conveying mechanism 122, and the overall movement of the telescopic belt conveyor can be facilitated through the rolling of the supporting roller 142. In addition, the tire of the supporting roller 142 can be made of flexible material, thereby reducing the damage of the supporting member to the supporting surface.

[0087] Optionally, one end of the second conveying mechanism is provided with a load device; the load device includes one or more of a mechanical arm and a palletizer.

[0088] Through the support of the supporting member to the second conveying mechanism, the stability of the second conveying mechanism is improved, so that the second conveying mechanism can be installed with a load device such as a mechanical arm or a palletizer, which has a higher requirement for the stability of the installation position, thereby improving the automation degree of the telescopic belt conveyor.

[0089] Optionally, referring to Figure 11 The first folding edge structure 111 is parallel to the assembly plane of the base 11, and the second folding edge structure 112 is used to connect the first folding edge structure 111 and the first conveying mechanism 121, respectively, and extends away from the central axis X of the conveying mechanism.

[0090] In the embodiment of the present application, since the telescopic belt conveyor is heavy when carrying goods, and there is a risk of side tilting during transportation, the first folding edge structure 111 and the second folding edge structure 112 on the base can provide support force in the side tilting direction, thereby reducing the risk of overall side tilting of the telescopic belt conveyor.

[0091] Optionally, referring to Figure 10 The number of the first telescopic rods 13 is at least two, and the at least two first telescopic rods 13 are arranged side by side; the number of the supporting members 14 is at least two, and the at least two supporting members 14 are arranged side by side.

[0092] Figure 10 The first telescopic rod 13 is two, and the supporting member 14 is two, and the plurality of first telescopic rods 13 and the plurality of supporting members 14 are arranged side by side, which can improve the support in the width direction of the telescopic belt conveyor, thereby improving the overall stability of the telescopic belt conveyor.

[0093] Optionally, referring to Figure 10The distance sensor 15 is further configured to detect an obstacle distance between an end of the second conveying mechanism 122 facing away from the first conveying mechanism 121 and an obstacle in the extending direction of the conveying mechanism; and the control device is specifically configured to: control the conveying mechanism to stop extending when the obstacle distance is less than or equal to a preset distance threshold.

[0094] In the embodiment of the present application, the control device detects the obstacle distance between the end of the second conveying mechanism 122 facing away from the first conveying mechanism 121 and the obstacle in the extending direction of the conveying mechanism through the distance sensor 15, and determines that the extending end of the conveying mechanism is too close to the obstacle when the obstacle distance is less than or equal to the preset distance threshold based on the safety of the preset distance threshold, and controls the conveying mechanism to stop extending at this time to avoid damage caused by the extending end of the conveying mechanism colliding with the obstacle.

[0095] It should be noted that, in addition to the distance sensor for detecting the distance between the second conveying mechanism and the support surface, an additional distance sensor can also be installed on the end of the second conveying mechanism 122 facing away from the first conveying mechanism 121 to detect the obstacle distance between the end of the second conveying mechanism 122 facing away from the first conveying mechanism 121 and the obstacle in the extending direction of the conveying mechanism through the additional distance sensor.

[0096] Referring to Figure 12 , a step flow chart of an embodiment of a telescopic belt conveyor control method of the present application is shown. It includes:

[0097] Step 101: obtaining the distance between the second conveying mechanism and the support surface through the distance sensor arranged on the second conveying mechanism.

[0098] Step 102: in the case of extending the conveying mechanism, controlling the first telescopic rod to telescope according to the distance detected by the distance sensor, so that the end of the support member facing away from the second conveying mechanism is in contact with the support surface.

[0099] The description of steps 101-102 can be specifically referred to the above-mentioned embodiments, which will not be described here again.

[0100] In summary, in the embodiment of the present application, the support member and the distance sensor are arranged on the second transmission mechanism of the telescopic belt conveyor other than the first transmission mechanism, so that when the transmission mechanism of the telescopic belt conveyor is extended, the control device can control the first telescopic rod to extend or retract according to the distance detected by the distance sensor, so that one end of the support member away from the second transmission mechanism is in contact with the support surface, thereby forming effective support for the second transmission mechanism, avoiding the front section of the telescopic belt conveyor being suspended in the air after being extended, improving the stability of the front section of the telescopic belt conveyor, and on the basis of meeting the stability of the front section of the telescopic belt conveyor, the material selection and mechanism of the first transmission mechanism can be designed to be lightweight, thereby reducing the equipment cost.
