Description

Technical Field

[0001] The invention belongs to the field of cargo conveying equipment, and in particular relates to a standing platform for a human-machine collaborative cargo conveyor. Background Art

[0002] As the demand for logistics transportation increases, the loading requirements for loading and unloading machines, conveying equipment, etc. are also getting higher and higher. The existing equipment like this is designed to adapt to large vans or containers. The human-machine collaborative conveyor station platform is relatively wide in overall design to accommodate the placement of goods on both sides of the box.

[0003] However, this design has the problem that the machine body is wide and bulky, and it is not flexible in normal use and movement. Moreover, it takes up a relatively large storage space and cannot enter the compartment of a medium-sized truck. The existing standing platform is usually not retractable, and the width of the whole machine is quite large, and the space passability is poor. In addition, the existing standing platform relies on two column chains to pull up and down. The design affects the passability and space interference due to the setting of the columns, and is not flexible during use.

[0004] CN 114560229 A discloses a conveying device, which increases the conveying range of the conveying unit by adjusting the structure of the conveying unit, but does not adjust the standing platform. The following problems will occur accordingly: (1) Due to the expansion of the conveying range (horizontal and vertical expansion), the standing platform area has not been expanded accordingly, resulting in inconvenience for operators to transfer goods. (2) In order to ensure the stability of the standing platform, the standing platform is generally set close to the ground and installed on the front side of the frame of the conveying device, which leads to poor passability of the conveying device.

[0005] CN 206265905 U discloses an automatic telescopic belt conveyor for loading and unloading vehicles, wherein a standing platform is directly hinged to a bracket at the end of the conveyor belt, and can synchronously follow the up and down swing or left and right swing of the conveyor belt. However, since the conveyor belt has a certain length, if the standing platform is directly installed at the end of the conveyor belt, considering the problem of arm torque, a motor with sufficient torque is required to achieve this, which virtually increases the production cost. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a standing platform for a human-machine collaborative cargo conveyor with adjustable width and height of the standing platform.

[0007] The object of the present invention is achieved as follows: a standing platform for a human-machine cooperative cargo conveyor, the main body of which is the standing platform, which is installed at the front part of the frame of the human-machine cooperative cargo conveyor; it includes a base, which is installed in front of the frame; a top seat, which is located above the base; a lifting mechanism, which is connected between the base and the top seat, and controls the top seat to move up and down relative to the base; a standing platform, which is located above the top seat and is connected to the top seat at the front and rear sides, and a chamber is formed between the standing platform and the top seat; a sliding platform, which is located in the chamber, is provided with two sliding platforms and is distributed left and right, and the sliding platforms are both slidably installed on the surface of the top seat; and a transmission mechanism, which is connected to the two sliding platforms, and drives the two sliding platforms to move toward or in the opposite direction;

[0008] The transmission mechanism drives the two sliding platforms to move toward each other so that they are completely retracted into the chamber, or drives the two sliding platforms to move in the opposite direction so that they extend out of the left and right ends of the standing platform to form an extended standing area.

[0009] The advantages of the present invention are as follows:

[0010] 1. The standing platform is equipped with a lifting mechanism, and the sliding platform can expand the lateral area of ​​the standing platform to adapt to the swing range of the conveying device to the greatest extent, ensuring that the operator can reasonably adjust the horizontal position and height of the standing platform according to the position of the output end of the conveying device, ensuring the position of the operator and the output end of the conveying device is adapted, and improving work efficiency.

[0011] 2. The setting of the base lifting mechanism can make the standing platform drop to the bottom during operation to ensure the stability of the standing platform. During the driving process of the conveying device, the chassis of the entire equipment can be improved in disguise by lifting the base lifting mechanism to ensure the passability of the conveying device.

DETAILED DESCRIPTION

[0023] like Figure 1-8 As shown: a standing platform for a human-machine collaborative cargo conveyor, the main body of which is a standing platform 2, which is installed at the front of the frame 11 of the human-machine collaborative cargo conveyor 1; it includes a base 21, which is installed in front of the frame 11; a top seat 22, which is located above the base 21; a lifting mechanism, which is connected between the base 21 and the top seat 22, and controls the top seat 22 to move up and down relative to the base 21; a standing platform 24, which is located above the top seat 22 and is connected to the top seat 22 at the front and rear sides, and a chamber is formed between the standing platform 24 and the top seat 22; a sliding platform 25, which is located in the chamber, is provided with two and the two sliding platforms 25 are distributed left and right, and the sliding platforms 25 are slidably installed on the surface of the top seat 22; and a transmission mechanism 26, which is connected to the two sliding platforms 25, and drives the two sliding platforms 25 to move toward or in the opposite direction;

[0024] The transmission mechanism 26 drives the two sliding platforms 25 to move toward each other so that they are completely retracted into the chamber, or drives the two sliding platforms 25 to move in the opposite direction so that they extend out of the left and right ends of the standing platform 24 to form an extended standing area.

[0025] Since the last conveyor belt of the conveying device can swing left and right and up and down, in order to cover the range covered by its output end, the standing platform 2 here needs to consider lifting and lowering as well as left and right expansion; however, these processes also need to be reversible, otherwise it may affect the passability of the conveying device in the later stage. Specifically, since the standing platform 2 is integrally connected to the human-machine collaborative cargo conveyor, the maximum width of any component in the human-machine collaborative cargo conveyor and the standing platform 2 is the maximum width of the entire product; in order to adapt to the conveying device ferry of the human-machine collaborative cargo conveyor, the standing platform 2 is directly and irreversibly widened, which will affect the passability of the entire equipment during driving.

[0026] In summary, the lifting mechanism of the present invention can move the top seat 22 up and down. Since the standing platform 24 is arranged on the top seat 22 and is used for standing people, the standing platform 24 can move up and down synchronously; in addition, two sliding platforms 25 are designed, which can extend outward from both sides of the standing platform 24 to form a new standing area in the left and right directions, thereby ensuring the operator's operating range in the left and right directions.

[0027] Example 1

[0028] like Figure 2-4 As shown: the two sliding platforms 25 are rotationally symmetrical, and the inner edges of the sliding platforms 25 are respectively provided with an outward extension plate 251 and an inward missing groove 252, wherein the extension plate 251 and the missing groove 252 have complementary contours; so that when the two sliding platforms 25 move toward each other, the extension plate 251 of any sliding platform 25 can be inserted into the missing groove 252 of the other sliding platform 25; the facing sides of the extension plates 251 of the two sliding platforms 25 are provided with racks 253;

[0029] The transmission mechanism 26 includes a telescopic cylinder 261 and a transmission gear 262. The telescopic cylinder 261 is installed on the top seat 22 and the output end is connected to one of the racks 253. The transmission gear 262 rotates on the top surface of the top seat 22, and the transmission gear 262 is meshed with the racks 253 of the two extension plates 251.

[0030] The transmission gear 262 is matched with two racks 253, so that the two sliding platforms 25 can move toward or in opposite directions; wherein, the telescopic cylinder 261 is connected to one of the racks 253, driving the rack 253 to reciprocate, and under the action of the transmission gear 262, the other rack 253 can be driven to reciprocate, so that the sliding platform extends to both sides, achieving the effect of expanding the platform area. It should be noted that the telescopic cylinder 261 can also be eliminated here, and a rotating motor can be configured for the transmission gear 262, and the motor is connected to the top seat 22.

[0031] The top of the top seat 22 is provided with multiple groups of limiting rails 221 arranged in sequence front to back and extending left to right, and the bottom of the sliding platform 25 is provided with multiple groups of linear sliders 254 connected to the limiting rails 221; the use of limiting rails can prevent the sliding platform 25 from warping due to uneven force caused by external force after extending outward.

[0032] A guardrail 255 is provided on the outer edge of the sliding platform 25 to provide protection for the operator from falling.

[0033] Example 2

[0034] like Figure 5 , 6 As shown: the lifting mechanism is a cross-type lifting mechanism, including two groups of cross arms 231 and a hydraulic cylinder 232 located between the base 21 and the top seat 22; wherein the cross arm 231 is formed by hingedly connecting the middle parts of two connecting arms 233; the left end of one of the cross arms 231 in any cross arm 231 is hinged to the left side of the top surface of the base 21, and the right end of the cross arm 231 is provided with a walking wheel 234, and the walking wheel 234 is in rolling cooperation with the bottom surface of the top seat 22; the left end of another cross arm 231 in any cross arm 231 is hinged to the left side of the bottom surface of the top seat 22, and the right end of the cross arm 231 is provided with a walking wheel 234, and the walking wheel 234 is in rolling cooperation with the top surface of the base 21; the two groups of cross arms 231 are linked to each other by a connecting rod 235, the fixed end of the hydraulic cylinder 232 is hinged to the right side of the top surface of the base 21, and the movable end of the hydraulic cylinder 232 is hinged to the connecting rod 235.

[0035] The extension and retraction of the hydraulic cylinder 232 can drive the opening and closing of the cross arm 231, thereby driving the top seat 22 to move up and down. The principle of this structure is basically the same as that of the existing cross-type lifting platform, and there are differences in the walking wheel part, so the present invention will not elaborate on the principle.

[0036] Example 3

[0037] like Figure 7 , 8As shown: it also includes a base lifting mechanism 27, which is installed in front of the frame 11 and connected to the base 21; the base lifting mechanism 27 includes a base plate 271, a base plate slide rail 272, a lifting frame 273, a slide seat 274 and a driving mechanism; the base plate 271 is installed on the front side of the frame 11, and a plurality of groups of base plate slide rails 272 arranged in sequence from left to right are installed on the front side of the base plate 271, the lifting frame 273 is located in front of the base plate 271, and a slide seat 274 is provided on the back of the lifting frame 273, the lifting frame 273 is installed on the base plate slide rail 272 through the slide seat 274 and guided by the base plate slide rail 272 to achieve up and down reciprocating motion; the driving mechanism is installed on the front side of the base plate 271 and is linked with the lifting frame 273, and the driving mechanism controls the up and down movement of the lifting frame 273; the base 21 is installed on the lifting frame 273.

[0038] Here, the lifting frame 273 is controlled by the driving mechanism to rise and fall, thereby controlling the rise and fall of the base 21; when working, the base 21 is controlled to touch the ground to ensure the stability of the entire standing platform. When it is necessary to travel, the base 21 is raised to raise the chassis in disguise, thereby improving the passability of the conveying device.

[0039] The driving mechanism includes a driving motor 275 and a turbine 276. The driving motor 275 is installed on the frame 11. The turbine 276 is located on the front side of the base plate 271 and is connected to the output shaft of the driving motor 275. A lifting rack (omitted in the figure) cooperating with the turbine 276 is provided on the back of the lifting frame 273. Here, the lifting and lowering of the lifting frame is controlled by the cooperation of the turbine and the lifting rack.

[0040] The front side of the base plate 271 is also provided with a limiting column 277, and the lifting frame 273 is provided with a vertical guide hole 278 for the limiting column 277 to pass through; the limiting column 277 and the guide hole 278 cooperate to mainly guide the lifting of the base plate.

[0041] The lifting frame 273 includes a mounting plate 2731 and a plurality of support plates 2732 arranged at the lower edge of the mounting plate and extending forward, and the base 21 is supported on the support plates 2732. A reinforcing rib 2733 is provided between the mounting plate 2731 and the support plate 2732. The standing platform is supported by a plurality of support plates, and the mounting plate is a whole, which facilitates the installation of various components. A reinforcing rib 2733 is provided between the mounting plate 2731 and the support plate 2732 to ensure the bearing capacity of the support plate.

[0042] It should be noted that the lifting and lowering of the lifting mechanism of the present invention, the extension and retraction of the sliding platform, and the lifting and lowering of the base lifting mechanism are all controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field, and the provision of power is also common knowledge in this field, so the present invention will no longer explain the control method and circuit connection in detail.

[0043] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
