Description

Technical Field

[0001] This application relates to the field of logistics handling technology, and more specifically, to a control device for an emergency stop knob. Background Technology

[0002] AGVs (Automated Guided Vehicles) play a very important role in the current logistics and transportation process. AGVs are industrial vehicles that load goods automatically or manually, travel automatically along a set route or tow a cargo trolley to a designated location, and then load and unload goods automatically or manually.

[0003] AGVs are generally equipped with an emergency stop knob. When an AGV malfunctions, its wheels lock up and it cannot move. The emergency stop knob needs to be pressed and rotated to restart the AGV. However, when an AGV is moving with a large rack on its back, because the AGV is smaller than the rack and has a lower height, if the AGV malfunctions at this time, the rack's interference and the limited length of the human hand make it difficult and potentially dangerous to control the emergency stop button. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a control device that facilitates pressing and controlling the rotation of the emergency stop knob.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0006] This application provides a control device for an emergency stop knob, comprising: a lever; a locking member and a linkage mechanism, the linkage mechanism being disposed within the lever and abutting against the locking member, the locking member being switchable between an expanded state and a contracted state, the radial dimension of the locking member being larger than that of the emergency stop knob in the expanded state and smaller than that of the emergency stop knob in the contracted state; and a control member located at one end of the lever and connected to the linkage mechanism, used to control a portion of the linkage mechanism to move along the axial direction of the lever; when a portion of the linkage mechanism moves away from the locking member, the linkage mechanism is used to switch the locking member from the expanded state to the contracted state.

[0007] In one embodiment, the locking member includes an extension section and a locking body, a portion of the extension section protruding outward along the radial direction of the locking body;

[0008] The linkage mechanism includes a first linkage part, the end of which abuts against the extension section. The first linkage part can move toward the extension section so that the extension section is compressed inward toward the radial direction of the locking body.

[0009] In one embodiment, the locking body has a notch, the extension is connected to the locking body, and a portion of the extension passes through the notch and protrudes outward in the radial direction of the locking body.

[0010] In one embodiment, the rod body includes a receiving portion and a rod portion, the radial dimension of the receiving portion being larger than the radial dimension of the rod portion, and the locking member further includes a connecting section, one end of which is fixedly connected to the locking body, and the other end of which is connected to the receiving portion.

[0011] In one embodiment, the first linkage includes a first bending point and a second bending point;

[0012] The control device further includes an adapter, which is fixedly connected to the receiving portion, and the first linkage portion is rotatably connected to the adapter at the second bending point.

[0013] In one embodiment, the linkage mechanism further includes a second linkage part, which is rotatably connected to the first linkage part; the control device further includes a universal coupling, the two ends of which are respectively connected to the first linkage part and the second linkage part.

[0014] In one embodiment, the linkage mechanism further includes a third linkage part, which extends within the rod portion. One end of the third linkage part is rotatably connected to the second linkage part, and the other end is connected to the control member. The control member can drive the third linkage part to move away from the locking member.

[0015] In one embodiment, the control component includes a movable part and a fixed part. The movable part is connected to one end of the third linkage part. The movable part can rotate toward the fixed part and pull the third linkage part.

[0016] In one embodiment, the control device further includes a telescopic member, which is sleeved on the outer periphery of the portion of the third linkage that protrudes from the outer part of the rod, and abuts against the movable part and the rod, respectively.

[0017] In one embodiment, at least one fixed support block is fixedly provided inside the rod portion, the fixed support block is fixedly connected to the rod portion, the third linkage portion passes through the fixed support block, and there is a gap between the third linkage portion and the fixed support block.

[0018] In one embodiment, the control device further includes a friction element for increasing friction with the emergency stop knob, the friction element being disposed on the inner peripheral wall of the locking member.

[0019] The technical solution of this application has the following beneficial effects:

[0020] 1. By setting a linkage mechanism in the rod body, one end of the linkage mechanism is connected to the control component, and the other end abuts against the locking component. The locking component can switch between an expanded state and a contracted state. The radial dimension of the locking component in the expanded state is larger than that of the emergency stop knob, and the radial dimension in the contracted state is smaller than that of the emergency stop knob. When the AGV malfunctions, the control device is extended into the space between the shelf and the ground, so that the locking component is located on the outer periphery of the emergency stop knob. The control component controls the locking component to be locked and surrounds the outer periphery of the emergency stop knob. Furthermore, the emergency stop knob can be pressed or rotated without having to reach the emergency stop knob by hand, thus improving the convenience and safety of operation.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0029] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figure 1 As shown, this application provides a control device for an emergency stop knob. When an AGV malfunctions, the AGV can be moved by pressing or rotating the emergency stop knob, without manual operation, thus improving the convenience and safety of operation.

[0031] Furthermore, the embodiments of this application are not limited to controlling the emergency stop knob on the AGV; they can also be applied to the emergency stop knobs of some roller shutter doors that are located at a distance.

[0032] like Figures 1 to 3 As shown, the control device includes a rod 1, a locking element 2, and a linkage mechanism 3. The linkage mechanism 3 is located inside the rod 1 and abuts against the locking element 2. The locking element 2 can switch between an expanded state and a contracted state. In the expanded state, the radial dimension of the locking element 2 is larger than the emergency stop knob, and in the contracted state, the radial dimension is smaller than the emergency stop knob. The control device also includes a control element 4, which is located at one end of the rod 1 and connected to the linkage mechanism 3. It is used to control the partial movement of the linkage mechanism 3 along the axial direction of the rod 1. When the AGV malfunctions... When the AGV is locked, the control device is extended into the space between the shelf and the ground, so that the locking part 2 is located on the outer periphery of the emergency stop knob. The control part 4 can control a part of the linkage mechanism 3 to move away from the locking part 2, so that the locking part 2 changes from an expanded state to a contracted state, thereby wrapping around the outer periphery of the emergency stop knob. Then, the control device presses the emergency stop knob or rotates the control knob to release the AGV from the locked state, so that the AGV can move. This eliminates the need for manual operation by reaching for the emergency stop knob, improving the convenience and safety of operation.

[0033] Optionally, the locking element 2 is in an expanded state under normal conditions, and changes from an expanded state to a contracted state when it is subjected to force by the linkage mechanism 3.

[0034] Optionally, the rod 1 is a through structure and can be made of metal, such as aluminum alloy.

[0035] like Figure 2 , 4As shown in Figure 5, in one embodiment, the locking member 2 includes an extension section 23 and a locking body 21. A portion of the extension section 23 protrudes outward along the radial direction of the locking body 21. The linkage mechanism 3 includes a first linkage part 31. The end of the first linkage part 31 abuts against the extension section 23. The first linkage part 31 can move toward the extension section 23 so that the extension section 23 is compressed inward toward the radial direction of the locking body 21. This further realizes that the locking body 21 and the extension section 23 cooperate to surround the outer periphery of the emergency stop knob, improving the stability between the locking member 2 and the emergency stop rotation, and providing convenience for subsequent control of pressing and rotating the emergency stop knob.

[0036] Optionally, the locking body 21 has a cylindrical structure, which allows the locking body 21 to fit around the emergency stop knob, increasing the contact area between the locking body 21 and the emergency stop knob, improving ease of operation, and making it easier to control the emergency stop knob.

[0037] Optionally, the number of extension sections 23 can be set to two, with the two extension sections 23 arranged opposite each other. Correspondingly, an additional first linkage part 31 and a second linkage part 32, as well as a converter 5, are also required. The two first linkage parts 31 and the second linkage part 32 are controlled simultaneously by a third linkage part 33, thereby further compressing the radial dimension of the locking member 2 and thus increasing the locking force of the locking member 2 on the emergency stop knob.

[0038] like Figure 4 and 5 As shown, in one embodiment, the locking body 21 has a notch 22, and the extension section 23 is connected to the locking body 21. The extension section 23 partially passes through the notch 22 and protrudes outward in the radial direction of the locking body 21, thereby providing an abutment position for the first linkage part 31. After the first linkage part 31 applies force to the extension section 23, the extension section 23 can pass through the notch 22 and fit tightly against the emergency stop knob, improving stability.

[0039] Optionally, the notch 22 extends along the circumferential direction of the locking body 21, thereby reducing the obstruction of the locking body 21 on the extension section 23 and allowing more of the extension section 23 to fit against the emergency stop knob.

[0040] Optionally, the width of the notch 22 along the axial direction of the locking member 2 is greater than the width of the extension 23, so that the extension 23 can pass freely through the notch 22.

[0041] like Figures 1 to 3As shown, in one embodiment, the rod 1 includes a receiving portion 12 and a rod portion 11. The radial dimension of the receiving portion 12 is larger than the radial dimension of the rod portion 11, thereby providing a receiving space for the locking member 2, the first linkage portion 31, and the second linkage portion 32. The locking member 2 also includes a connecting section 24. One end of the connecting section 24 is fixedly connected to the locking body 21, and the other end is connected to the receiving portion 12, thereby improving the stability between the locking member 2 and the receiving portion 12 and preventing the locking member 2 from shaking in the receiving portion 12 during operation.

[0042] Optionally, the connecting section 24 and the receiving part 12 can be connected by welding.

[0043] Optionally, the radial dimension of the receiving portion 12 is larger than the radial dimension of the locking member 2, and the locking member 2 is received in the receiving portion 12. The connecting section 24 can also be integrally formed with the locking body 21 to improve the stability of the locking member 2 and the receiving portion 12.

[0044] like Figures 3 to 5 As shown, optionally, multiple connecting segments 24 can be provided to increase the stability of the locking member 2 and the receiving part 12. The connecting segments 24 can be spaced apart on the outer periphery of the locking body 21 to distribute the stress points connected to the receiving part 12.

[0045] In one embodiment, the first linkage 31 includes a first bending point and a second bending point; the control device also includes a connector 5, which is fixedly connected to the receiving part 12. The first linkage 31 is rotatably connected to the connector 5 at the position of the second bending point, so that the first linkage 31 can rotate relative to the connector 5 to apply force to the extension section 23.

[0046] Optionally, the adapter 5 includes an adapter base and a support arm connected to the adapter base. The two support arms are arranged in parallel relative to each other. The adapter base is fixedly connected to the receiving part 12. The second bending point is located between the two support arms. The pin passes through the two support arms and the position of the second bending point, thereby realizing the rotatable connection between the adapter 5 and the first linkage part 31. Furthermore, the first linkage part 31 can rotate about the position connected to the adapter 5 as the axis.

[0047] like Figure 1 and 2 As shown, optionally, in the expanded state, the first linkage part 31 abuts against the extension section 23 in the direction perpendicular to the extension section 23. Thus, when the first linkage part 31 rotates relative to the adapter 5, it can apply a force perpendicular to the extension section 23 to compress the extension section 23 inward in the radial direction of the locking body 21. This makes operation easier and improves the locking effect of the locking part 2. In addition, it also avoids the situation where the first linkage part 31 and the extension section 23 are misaligned, which would prevent the first linkage part 31 from being unable to compress the extension section 23.

[0048] Optionally, the first linkage part 31 can be configured with a first bending point and a second bending point to make the first linkage part 31 an open quadrilateral structure.

[0049] like Figure 1 As one embodiment, the linkage mechanism 3 further includes a second linkage part 32, which is rotatably connected to the first linkage part 31; the control device further includes a universal coupling (not shown in the figure), the two ends of which are respectively connected to the first linkage part 31 and the second linkage part 32, so that the second linkage part 32 can transmit force to the first linkage part 31 through the universal coupling.

[0050] Optionally, the second linkage 32 is inclined toward the center of the rod 11 in the receiving part 12 for transmission connection with the third linkage 33. This results in the first linkage 31 and the second linkage 32 not being in the same plane in space. If they are only connected by ordinary pins, the force transmission effect will be affected. Therefore, by setting a universal coupling, the universal coupling can transmit the force generated by the second linkage 32 to the first linkage 31, so that the first linkage 31 compresses the extension 23, making the transmission between the second linkage 32 and the first linkage 31 smoother and more convenient to operate.

[0051] like Figure 1 and 2 As shown, in one embodiment, the linkage mechanism 3 also includes a third linkage part 33, which extends within the rod part 11. One end of the third linkage part 33 is rotatably connected to the second linkage part 32, and the other end is connected to the control member 4. The control member 4 can drive the third linkage part 33 to move away from the locking member 2, thereby causing the third linkage part 33 to drive the second linkage part 32 to move away from the locking member 2 as well. While the second linkage part 32 is moving, the first linkage part 31 also applies a force to the extension section 23, causing the extension section 23 to compress inward toward the radial direction of the locking body 21, thereby locking the emergency stop knob.

[0052] Optionally, the third linkage 33 and the second linkage 32 are connected by a universal coupling.

[0053] Optionally, the first linkage part 31, the second linkage part 32 and the third linkage part 33 can be rod-shaped structures or sheet-shaped structures.

[0054] like Figure 1 As shown, in one embodiment, the control member 4 includes a movable part 41 and a fixed part 42. The movable part 41 is connected to one end of the third linkage part 33. The movable part 41 can rotate toward the fixed part 42 and pull the third linkage part 33, thereby transmitting force sequentially to the first linkage part 31 and applying force to the extension section 23.

[0055] Optionally, the movable part 41 and the fixed part 42 are both located at one end of the rod 11, and grooves adapted to human hands can be provided on the movable part 41 and the fixed part 42 to facilitate workers to hold the movable part 41 and the fixed part 42.

[0056] like Figure 1 and 2 As shown, in one embodiment, the control device also includes a telescopic member 6. The telescopic member 6 is sleeved on the outer periphery of the portion of the third linkage 33 that protrudes from the rod portion 11, and abuts against the movable portion 41 and the rod portion 11 respectively. Thus, when the movable portion 41 rotates toward the fixed portion 42, the telescopic member 6 is pulled, making the telescopic member 6 longer. When the movable portion 41 is released, the telescopic member 6 automatically returns to its original position, pulling the movable portion 41 back to its original position.

[0057] Optionally, the telescopic component 6 can be a spring.

[0058] like Figure 1 and 2 As shown, in one embodiment, at least one fixed support block 8 is fixed inside the rod 11, the third linkage part 33 passes through the fixed support block 8, and there is a gap between the third linkage part 33 and the fixed support block 8, thereby improving the stability of the third linkage part 33 inside the rod 11 and preventing the third linkage part 33 from shaking.

[0059] like Figure 3 As shown, in one embodiment, the control device also includes a friction element 7, which is disposed on the inner peripheral wall of the locking element 2. When the locking element 2 surrounds the emergency stop knob, the friction element 7 can increase the friction between it and the emergency stop knob, thereby improving the stability of operation.
