Description

TECHNICAL FIELD

[0001] The utility model relates to the motion control field of low-speed storage and transport vehicle, more particularly, it relates to a platform for high-position picking vehicle. BACKGROUND

[0002] The high-position picking vehicle is a low-speed storage and transport vehicle for industrial use, a mechanical equipment used in warehouses and logistics centers, mainly used for picking, carrying and stacking goods on high shelves. The operator drives the high-position picking vehicle to move between shelves, and lifts the platform carrying the operator to lift the operator, so as to take or place goods on the high shelf.

[0003] In order to be able to pick and place goods at high position, the operator needs to extend out of the platform, and the operator needs a certain space for movement in the platform. In addition, due to the process requirements of the high-position picking vehicle, the operator also needs to frequently enter and exit the platform. Therefore, the existing high-position picking vehicle is provided with rotatable armrests on the left and right sides of the platform. The armrests are lowered to a horizontal state to achieve relative closure of the platform.

[0004] However, due to the lack of forced detection of the lowered armrests, many operators of the existing high-position picking vehicle perform illegal operations without lowering the armrests, resulting in safety accidents. SUMMARY

[0005] The utility model overcomes the deficiency of the lack of forced detection of the lowered armrests of the existing high-position picking vehicle, and provides a platform for high-position picking vehicle, which can forcibly require the armrests to be lowered, otherwise the necessary functions of the high-position picking vehicle will be missing.

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0007] A platform for high-position picking vehicle, the high-position picking vehicle includes a vehicle frame, the platform is connected to the vehicle frame by lifting, both sides of the platform are provided with armrests, the armrests can rotate to reach a horizontal state or a vertical state, the armrests include upper armrests and lower armrests, the upper armrests and the lower armrests are drivingly connected and rotate synchronously, the platform is provided with a seat, when the armrests are in the horizontal state, the lower armrests are in contact with the seat, the platform is provided with a detection circuit, the detection circuit is in communication connection with a controller in the high-position picking vehicle, when both the lower armrests are in contact with the seat, the detection circuit sends a power on-off signal of the power device of the high-position picking vehicle to the controller of the high-position picking vehicle.

[0008] The platform is located on the frame and can be lifted relative to the frame. The operator is located in the platform and moves synchronously with the movement of the platform. In order to reduce the weight and facilitate the operation of the operator, the platform adopts a frame structure, and protective arms capable of adjusting the horizontal or vertical position are arranged on both sides to protect the operator in the platform and prevent the operator from falling out and causing safety accidents.

[0009] The protective arms include upper protective arms and lower protective arms. The upper protective arms are located above the lower protective arms and limit the excessive protrusion of the upper body and lower body of the operator out of the platform, respectively. The upper protective arms and the lower protective arms are linked and rotate synchronously to reduce the operation amount.

[0010] The upper protective arms and the lower protective arms are arranged on one side of the platform, and the arrival seats are arranged on the other side. When the lower protective arms are horizontally arranged, the lower protective arms are in contact with the arrival seats, thereby satisfying the detection circuit and causing the detection circuit to generate a signal. When both of the lower protective arms generate the signal, the detection circuit sends a communication signal to the controller of the high-level sorting vehicle. At this time, the controller can accept the control input signal of the console related to the power device on the high-level sorting vehicle to operate the corresponding power device.

[0011] As a preferred embodiment, the upper protective arms are rotatably connected to the platform through upper hinge points, the lower protective arms are rotatably connected to the frame through lower hinge points, the upper hinge points and the lower hinge points are located on the same side of the platform, a connecting rod is arranged between the upper protective arms and the lower protective arms, and the connecting rod is rotatably connected to the upper protective arms and the lower protective arms. The upper protective arms and the lower protective arms realize synchronous movement through the connecting rod.

[0012] As a preferred embodiment, the lower protective arms are provided with connecting ears at the lower hinge points, the platform is rotatably connected with elastic members, the elastic members are rotatably connected with the connecting ears, the two ends of the stroke limit of the elastic members correspond to the horizontal position and the vertical position of the protective arms, respectively, and the functional image between the stroke of the elastic members and the deformation amount of the elastic members is a downward-opening parabola. The setting of the elastic members makes the elastic potential energy of the elastic members at the corresponding stroke corresponding to the horizontal position and the vertical position the lowest, thereby satisfying the principle of minimum potential energy. At this time, the whole system is in a balanced state. In actual operation, the operator only needs to turn over the protective arms to the point where the compression amplitude of the elastic members is the largest, and then the elastic members can drive the connecting rod and the protective arms to the other stroke limit, thereby improving the convenience.

[0013] As a preferred embodiment, the elastic members are gas struts. The gas struts have better adjustment of the elastic force than other elastic members, and the reliability of the gas struts is stronger.

[0014] As preferred, the detection circuit comprises detection switches, which generate corresponding signals according to the pressure received. The detection switches can adopt the principle similar to micro-switches or pressure-sensitive switches to generate signals through touching and pressure. The two detection switches corresponding to the two arms can be connected to an AND gate, and the AND gate is connected to the controller or directly built in the controller, so that the technical effect that the power device of the high-picking vehicle can be started only when the two arms are in the horizontal state is realized.

[0015] As preferred, a console is arranged on the platform, the controller is arranged in the console, the upper hinge point and the lower hinge point are arranged on the side of the platform away from the console, and the detection switches are arranged on the side of the platform close to the console and connected to the controller in line.

[0016] As preferred, flexible buffer blocks are further arranged on the in-place seats. The structure avoids the rigid contact between the lower arm and the in-place seat and reduces the damage of the lower arm to the detection switches.

[0017] Compared with the prior art, the utility model has the beneficial effects that:

[0018] (1) The upper arm and the lower arm are connected through the connecting rod, and the operation amount is reduced.

[0019] (2) The cooperation of the lower arm and the detection switches forces the operator to operate the equipment only after the lower arm is placed down, and the safety is improved.

[0020] (3) The lower arm is connected with the elastic member, and only needs to be rotated over the threshold value to automatically switch to another state, and the operation amount is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0032] Embodiment: <00OO075>A platform 2 for a high-level order picker truck, as shown in the figure, wherein the high-level order picker truck includes a vehicle frame 1, and the platform 2 is connected to the vehicle frame 1 in a lifting manner. The platform 2 has a space for an operator to enter and control the high-level order picker truck. Spaces for the operator to enter are provided on both sides of the platform 2. The operator can limitedly lean out from both sides and the front beyond the space of the platform 2. Figure 1 Based on this, guard arms 3 are provided on both sides of the platform 2, and the guard arms 3 can rotate to reach a horizontal state or a vertical state. The horizontal state is approximately horizontal. In this state, the operator in the platform 2 cannot break through the阻拦 of the guard arms 3 and extend excessively beyond the platform 2. In the vertical state, the operator can freely enter and exit the platform 2.

[0034] Based on this, guard arms 3 are provided on both sides of the platform 2, and the guard arms 3 can rotate to reach a horizontal state or a vertical state. The horizontal state is approximately horizontal. In this state, the operator in the platform 2 cannot break through the阻拦 of the guard arms 3 and extend excessively beyond the platform 2. In the vertical state, the operator can freely enter and exit the platform 2.

[0035] As shown in the figure Figure 2 It should be noted that there is an unclear word "阻拦" in the original text. I translated it as "阻拦" first, and you can adjust it according to the actual situation.As shown, the arm 3 includes an upper arm 4 and a lower arm 6, wherein the upper arm 4 is arranged at the position corresponding to the chest of an adult, and the lower arm 6 is arranged at the position corresponding to the thigh of an adult. The upper arm 4 and the lower arm 6 are drivingly connected and synchronously rotate. The platform 2 is provided with a position reaching seat 11, which is in the extension direction of the lower arm 6. When the arm 3 is in the horizontal state, the lower arm 6 is in contact with the position reaching seat 11. The platform 2 is provided with a detection circuit, which is in communication connection with the controller in the high-picking vehicle. When both lower arms 6 are in contact with the position reaching seat 11, the detection circuit sends a power on-off signal to the controller of the high-picking vehicle to start or stop the power device of the high-picking vehicle. The power device includes a power device for controlling the movement of the high-picking vehicle and a power device for controlling the lifting of the platform 2 relative to the vehicle frame 1.

[0036] Referring to Figure 3 Specifically, as shown, the detection circuit includes a detection switch 12, which generates a corresponding signal according to the pressure received. The two detection switches 12 corresponding to the two arms 3 can be connected to an AND gate, and then the AND gate is connected to the controller, or the AND gate is directly built into the controller, so as to achieve the technical effect that the power device of the high-picking vehicle can only be started when both arms 3 are in the horizontal state.

[0037] In some embodiments, the detection switch 12 is a micro switch, but it is not limited thereto. Those skilled in the art can set the detection switch 12 according to the actual positioning needs, for example, it can be a pressure sensitive sensor.

[0038] The platform 2 is provided with a control console 13, and the controller is arranged in the control console 13. The upper hinge point 5 and the lower hinge point 7 are both arranged on the side of the platform 2 away from the control console 13, and the detection switch 12 is arranged on the side of the platform 2 close to the control console 13. The detection switch 12 is in wire connection with the controller. The detection switch 12 is arranged close to the controller, and the wire harness is arranged closer.

[0039] The position reaching seat 11 is further provided with a flexible buffer block 14. This structure avoids the rigid contact between the lower arm 6 and the position reaching seat 11, and reduces the damage of the lower arm 6 to the detection switch 12.

[0040] Referring to Figure 4As shown, the upper arm 4 is rotatably connected to the platform 2 through an upper hinge point 5, and the lower arm 6 is rotatably connected to the vehicle frame 1 through a lower hinge point 7, the upper hinge point 5 and the lower hinge point 7 are located on the same side of the platform 2, a connecting rod 8 is arranged between the upper arm 4 and the lower arm 6, and the connecting rod 8 is hingedly connected to the upper arm 4 and the lower arm 6 respectively. The upper arm 4 and the lower arm 6 realize synchronous movement through the connecting rod 8. The lower arm 6 is provided with a connecting lug 9 at the lower hinge point 7, and the platform 2 is hingedly connected with an elastic element 10, the elastic element 10 is hingedly connected with the connecting lug 9, the two ends of the stroke limit of the elastic element 10 correspond to the horizontal state and the vertical state of the arm 3 respectively, and the functional image between the stroke of the elastic element 10 and the deformation amount of the elastic element 10 is a downward-opening parabola. The setting of the elastic element 10 makes the elastic potential energy of the elastic element 10 at the corresponding stroke in the corresponding horizontal state and vertical state the lowest, satisfying the principle of minimum potential energy, at this time, the whole system is in a balanced state. In actual operation, as long as the operator turns over the arm 3 to the point where the compression amplitude of the elastic element 10 is the largest, the elastic element 10 can drive the connecting rod 8 and the arm 3 to the other stroke limit, thereby improving the convenience. The elastic element 10 is a gas strut. Compared with other elastic elements 10, the gas strut has better adjustable elasticity, and the gas strut has higher reliability.

[0041] The platform 2 is located on the vehicle frame 1 and can be lifted relative to the vehicle frame 1. The operator is located in the platform 2 and moves synchronously with the movement of the platform 2. In order to be light and convenient for the operator to operate, the platform 2 adopts a frame structure, and arms 3 capable of adjusting the horizontal state or the vertical state are arranged on both sides to protect the operator in the platform 2, so as to prevent the operator from falling out and causing a safety accident.

[0042] The arm 3 includes an upper arm 4 and a lower arm 6. The upper arm 4 is located above the lower arm 6 and limits the upper body and the lower body of the operator from excessively protruding out of the platform 2. The two arms are linked and rotate synchronously to reduce the operation amount.

[0043] The upper arm 4 and the lower arm 6 are arranged on one side of the platform 2, and a position reaching seat 11 is arranged on the other side. When the lower arm 6 is in the horizontal state, the lower arm 6 is attached to the position reaching seat 11, thereby satisfying a detection circuit and making the detection circuit generate a signal. When both of the lower arms 6 generate signals, the detection circuit sends a communication signal to the controller of the high-position sorting vehicle, and at this time, the controller can accept the control input signal of the console 13 related to the power device on the high-position sorting vehicle to operate the corresponding power device. The device improves the safety of the high-position sorting vehicle and reduces the probability of safety accidents.

[0044] The above-described embodiments are only preferred schemes of the present application and do not limit the present application in any form. Other variants and modifications can be made without departing from the technical scheme recited in the claims.
