Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a car for a stacker, a cargo platform for a stacker and a stacker. Background Art

[0002] In stackers, the maintenance platform is usually composed of a guardrail structure, through which tools and cargo on the maintenance platform can easily fall, which may pose a danger to the personnel below. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0004] In view of this, in the first aspect, the utility model proposes a car for a stacker, comprising: a car body, which is provided with an entrance and exit; a door body assembly, which includes a door frame and a protective net, the door frame is connected to the car body, and the circumference of the protective net is connected to the door frame.

[0005] The car body is provided with an entrance and exit, through which the staff can enter and exit the car, and the staff can perform maintenance, care and control of the stacker in the car. A door assembly is installed on the car body, and the door assembly can open or close the entrance and exit.

[0006] A protective net is installed on the door frame. The protective net is located in the enclosed area of ​​the door frame. The protective net can prevent the work and goods in the car from falling through the door assembly to the outside of the car, thereby preventing tools and goods from causing danger to the staff outside the car and improving the safety of the staff working around the stacker. The protective net is a grid-like structure, which allows the staff inside and outside the car to understand each other's situation, which is conducive to handling emergency problems. The staff inside the car can quickly inform the staff outside the car of their demands through the protective net, improving the safety and communication convenience during the work process.

[0007] In addition, the car in the above technical solution provided by the utility model may also have the following additional technical features:

[0008] In some technical solutions, optionally, the door frame has a folded state and an unfolded state. In the folded state, the door body assembly opens the entrance and exit, and in the unfolded state, the door body assembly closes the entrance and exit, and the protective net can deform with the movement of the door frame.

[0009] The door assembly can be switched between a folded state and an unfolded state, so that the door assembly can open or close the entrance and exit. Specifically, when the user needs to enter or exit the car, the door assembly can be folded so that the door assembly opens the entrance and exit. When the entrance and exit need to be closed, the door assembly is switched to the unfolded state so that the door assembly closes the entrance and exit. If the door assembly is an outward-rotating way to open the entrance and exit, when there is an obstacle outside the car, the door assembly is difficult to open outward. If the door assembly is an inward-rotating way to open the entrance and exit, when there is a staff member standing in the car, the door assembly opened inward will be interfered by the staff member, and the way of opening outward or outward takes up more space. The door assembly is set to open the entrance and exit in a folding manner. Even if there are obstacles or staff members inside and outside the car, it will not affect the opening and closing of the door assembly. Moreover, the door assembly takes up less space when opening the entrance and exit, which is conducive to use in scenarios with limited space.

[0010] The protective net is made of deformable material. When the door frame is folded, the protective net can also be folded together, thereby avoiding the protective net interfering with the folding process of the door frame.

[0011] In some technical solutions, optionally, the door frame includes: multiple frames, the multiple frames are connected end to end in sequence, the protective net is circumferentially connected to the multiple frames, a frame located on the side of the multiple frames is connected to the car body, and two adjacent frames are rotatably connected so that a part of the door frame can rise or fall relative to the car body.

[0012] A plurality of frames are enclosed to form an annular structure, a frame located at the side of the plurality of frames is fixed on the car body, and two adjacent frames can be rotatably connected so that the door frame can be raised or lowered.

[0013] Specifically, when the user pushes the door frame upward, the two adjacent frames rotate relative to each other, and except for one frame fixed to the car body, the remaining frames rise, so that the multiple frames gradually fold, thereby opening the entrance and exit. Conversely, when the user stops pushing the door frame upward, the two adjacent frames also rotate relative to each other, and except for one frame fixed to the car body, the remaining frames fall, so that the multiple frames gradually unfold, thereby closing the entrance and exit.

[0014] Taking four frames as an example, when the door frame is in the expanded state, the four frames enclose a rectangular structure. When the door frame is pushed upward, since one frame is fixed on the car body, the other three frames will rise. At this time, the four frames enclose a parallelogram structure.

[0015] The door assembly is opened and closed by moving up and down, which can reduce the space occupied by the door assembly when opening and closing.

[0016] In some technical solutions, optionally, a plurality of hooks are provided on the frame, a plurality of grid holes are provided on the protective net, and the hooks pass through the grid holes so that the hooks and the protective net are hooked.

[0017] The protective net can be deformed with the folding of the door frame, and the protective net is a grid-like structure, so there are multiple grid holes on the protective net. Multiple hooks are arranged on any frame, and the hooks can pass through the grid holes, so that the protective net can be installed and fixed on the frame.

[0018] In a possible application, the number of sides of the protection net is the same as the number of frames, and one side of the protection net is fixed to one frame.

[0019] The protective net is fixed to the frame by hooks. The installation method of the protective net is relatively simple. Moreover, when the protective net is damaged, it is also convenient to disassemble and replace the protective net.

[0020] In some technical schemes, optionally, multiple frames include: a first frame, the first frame includes a support frame and a first mounting plate, the support frame is provided with a receiving groove, the receiving groove extends along the length direction of the support frame, the first mounting plate is arranged in the receiving groove, and the first mounting plate is provided with a hook; a second frame, the second frame includes a supporting plate and a second mounting plate connected in sequence, the second mounting plate is connected to the supporting plate, the end of the supporting plate extends into the receiving groove in the adjacent first frame, and the second mounting plate is provided with a hook.

[0021] Among the multiple frames, there are two types of frames. The first frame is a first frame composed of a support frame and a first mounting plate. A receiving groove is provided on the support frame, and the first mounting plate can be installed in the receiving groove. A hook is provided on the first mounting plate. When the protective net is connected to the hook on the first mounting plate, a part of the protective net extends into the receiving groove. Therefore, the connection position of the protective net and the first mounting plate is located in the receiving groove, and it is not easy for the staff or external structure to touch the connection position of the protective net and the first mounting plate, so that the protective net can be prevented from being scratched and separated from the first mounting plate, and the stable connection between the protective net and the first mounting plate is ensured. Compared with the method of directly processing and forming the hook on the inner wall of the receiving groove, the processing method of installing the first mounting plate with the hook into the receiving groove is simpler.

[0022] The second frame is a second frame composed of a load-bearing plate and a second mounting plate, a hook is arranged on the second mounting plate, and the protective net is fixed on the second mounting plate by the hook. Although the receiving groove on the support frame can shield the connection position of the protective net and the first mounting plate, it also increases the difficulty of disassembling the protective net. Therefore, a part of the side of the protective net can be exposed, that is, a part of the side of the protective net is installed on the second mounting plate. When disassembling the protective net, the protective net can be disassembled from the second mounting plate first, and the protective net will not be too tight at this time, so that it is convenient to disassemble the other side of the protective net from the first mounting plate. Similarly, when installing the protective net, the protective net can be installed on the first mounting plate first, and finally a part of the side of the protective net is fixed to the second mounting plate. In the above manner, the convenience of disassembling and assembling the protective net can be improved.

[0023] A separate second mounting plate is prone to deformation, and a bearing plate may be used to support the second mounting plate, thereby preventing the second mounting plate from being deformed and preventing the protective net from being separated from the second mounting plate.

[0024] In some technical solutions, optionally, the second frame also includes: a fixing plate, the fixing plate and the supporting plate are located on both sides of the second mounting plate, a portion of the fixing plate is bent compared to the second mounting plate, and the bent portion of the fixing plate is arranged opposite to the opening of the hook.

[0025] A fixing plate and a bearing plate are connected to both sides of the second mounting plate. The fixing plate can further strengthen the structure of the second mounting plate, thereby preventing the second reinforcement plate from being deformed.

[0026] A portion of the fixing plate is bent in a direction away from the second mounting plate, so that a portion of the fixing plate is tilted above the second mounting plate, and the bent portion of the second mounting plate is opposite to the opening of the hook, so that the second mounting plate can cover the opening of the hook, preventing workers or external structures from scratching the connection position between the protective net and the second mounting plate, and preventing the protective net from detaching from the second mounting plate.

[0027] In some technical solutions, optionally, the car also includes: a first supporting seat, connected to the car body, and in the expanded state, the supporting seat is used to support the frame located at the top of the multiple frames; a second supporting seat, connected to the car body, and in the expanded state, the supporting seat is used to support the frame located at the bottom of the multiple frames.

[0028] A first supporting seat and a second supporting seat are installed on the car body. When the door body assembly is in the unfolded state, the first supporting seat supports the top frame, and the second supporting seat supports the bottom frame. The first supporting seat and the second supporting seat limit the top frame and the bottom frame to prevent the top frame and the bottom frame from continuing to descend, thereby stably fixing the door body assembly in the position of closing the entrance and exit.

[0029] In some technical solutions, optionally, in the expanded state, the first supporting seat and the frame located at the top of the multiple frames are plugged into and limited by each other, and / or the second supporting seat and the frame located at the bottom of the multiple frames are plugged into and limited by each other.

[0030] When the first supporting seat supports the top frame, the first supporting seat and the top frame are also plugged into each other. At this time, the first supporting seat can limit the top frame to prevent the top frame from shaking, thereby ensuring that the structure of the door body assembly is not easily damaged. Moreover, by preventing the top frame from shaking, it is also possible to prevent the top frame from detaching from the first supporting seat, thereby ensuring that the first supporting seat can stably support the top frame.

[0031] Similarly, when the second supporting seat supports the bottom frame, the second supporting seat and the bottom frame are also plugged into each other. At this time, the second supporting seat can limit the bottom frame to prevent the bottom frame from shaking, thereby ensuring that the structure of the door body assembly is not easily damaged. Moreover, by preventing the bottom frame from shaking, it is also possible to prevent the bottom frame from detaching from the second supporting seat, thereby ensuring that the second supporting seat can stably support the bottom frame.

[0032] In some technical solutions, optionally, the car further includes: a door handle, and the door handle is arranged on a frame located at the top among the multiple frames.

[0033] A door handle is installed on the top frame, and the user can apply force to the door handle to lift or pull down the door frame, which is convenient for the staff to operate, thereby making it easier for the staff to fold or unfold the door body assembly.

[0034] In some technical solutions, optionally, a first limiting portion is provided on the door handle and a second limiting portion is provided on the car body. In the folded state, the first limiting portion and the second limiting portion are connected, and in the unfolded state, the first limiting portion and the second limiting portion are separated.

[0035] The staff folds the door assembly by lifting the door handle. If the door handle is released, the door assembly will automatically unfold under the action of gravity, which requires the user to continuously lift the door handle. Therefore, in order to avoid the above situation, a second limiter is provided on the car body. After the door handle is lifted, the first limiter and the second limiter can be connected. The second limiter limits the first limiter. At this time, the door assembly will not automatically unfold under the action of gravity. The user can let go and perform other operations, thereby improving the convenience of the staff at work. When the entrance and exit need to be closed, the first limiter is separated from the second limiter so that the door assembly can be unfolded.

[0036] In some technical solutions, optionally, the car body includes: side panels connected to the door body assembly; a bottom panel connected to the side panels and located at the bottom of the side panels; and a top panel connected to the side panels and located at the top of the side panels.

[0037] A top plate and a top plate are respectively provided on the top and bottom of the side plates. After the staff enters the car, the staff can stand on the top plate to work. At this time, the top plate is located above the staff. The top plate can prevent objects falling from the upper space from hitting the staff, thereby playing a protective role for the staff and helping to improve the safety of the staff at work.

[0038] In some technical solutions, optionally, an anti-slip portion is provided on the top of the bottom plate.

[0039] The staff stands on the bottom plate to work in the car. The upper surface of the bottom plate is provided with an anti-skid portion. The anti-skid portion can increase the friction on the soles of the staff and play an anti-skid function. The staff is not easy to slip on the bottom plate, which is conducive to improving the safety of the staff when working in the car.

[0040] In some technical solutions, optionally, the car also includes: a control panel connected to the car body.

[0041] The control panel is installed on the car body. When the cargo platform of the stacker fails or needs maintenance, the staff can enter the car area and control the stacker to move, the cargo platform to rise and fall, and the cargo fork of the cargo platform to extend and retract and retrieve through the control panel.

[0042] In some technical solutions, optionally, the car also includes: a door detection component, which is connected to the car body and the door body component. In the expanded state, the door detection component is used to output a door opening signal to the control panel.

[0043] A door detection component is installed on the car body and the door body assembly. The door detection component is used to detect whether the door body assembly is in an open state. When the door detection component detects that the door body assembly is in an open state, the door detection component can output a door opening signal to the control panel.

[0044] If the stacker is in operation when the staff is entering the car, it may cause harm to the staff. Therefore, the stacker can be controlled to stop running when the staff opens the door to ensure the safety of the staff when entering the car. After the staff enters the car, the door assembly is in a closed state. At this time, the door assembly no longer outputs a door opening signal, and the stacker can be controlled to operate normally.

[0045] In some technical schemes, optionally, the door detection assembly includes: a detection switch connected to the car body; a trigger member connected to the door body assembly, the trigger member can rotate with the door frame, in the folded state, the detection switch is separated from the trigger member, and in the unfolded state, the detection switch is in contact with the trigger member, so that the detection switch outputs a door opening signal.

[0046] When the entrance and exit are opened, the two adjacent frames will rotate with each other. The trigger is installed on the frame and can move with the frame. When the trigger contacts the detection switch, the trigger triggers the detection switch, and the detection switch outputs a door opening signal. When the door assembly is in a closed state, the trigger is separated from the detection switch. At this time, the trigger does not trigger the detection switch, and the detection switch no longer outputs a door opening signal. In this way, the detection switch can accurately detect whether the door assembly is in an open state, ensuring the safety of the staff at work.

[0047] In some technical solutions, optionally, the trigger member includes: a cam, the cam has a fan-shaped surface, and a groove is provided on the fan-shaped surface. In a folded state, the groove is opposite to the detection switch, and in an unfolded state, the fan-shaped surface is in contact with the detection switch.

[0048] When a groove is set on the fan-shaped surface, the radius of the bottom wall of the groove is smaller than the radius of the fan-shaped surface. When the groove is opposite to the detection switch, the cam does not contact the detection switch, and the detection switch is not triggered. When the fan-shaped surface is opposite to the detection switch, due to the larger radius of the fan-shaped surface, the fan-shaped surface contacts the detection switch, thereby triggering the detection switch.

[0049] In the second aspect, the utility model proposes a cargo platform for a stacker, comprising: a cargo platform body; a photoelectric bracket, connected to the cargo platform body, for outputting a detection signal for the goods; a fork, connected to the cargo platform body; and a car for a stacker as in the first aspect, the car being connected to the cargo platform body.

[0050] The fork can be used for picking up or placing goods. A sensor is provided on the photoelectric bracket, which is used to detect the information of the goods on the fork, for example, whether there is goods on the fork, the height and specifications of the goods, etc.

[0051] In some technical solutions, optionally, the first side of the car faces the photoelectric support and the fork, and the first side of the car is an open side.

[0052] When the staff needs to maintain the photoelectric bracket and the fork, since the first side of the car is an open side, the staff can enter the area where the photoelectric bracket and the fork are located from the first side of the car, which is convenient for users to enter the target area for maintenance.

[0053] In a third aspect, the utility model provides a stacker, comprising a cargo platform for a stacker as in the second aspect.

DETAILED DESCRIPTION

[0068] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0069] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0070] Refer to the following Figures 1 to 10 The invention describes a stacker car, a cargo platform for a stacker, and a stacker provided according to some embodiments of the invention.

[0071] Combination Figure 1 and Fig. 9 As shown, in an embodiment of the utility model, a car 100 for a stacker is proposed, comprising: a car body 110 and a door body assembly 120, the car body 110 is provided with an entrance and exit 111, the door body assembly 120 comprises a door frame 121 and a protective net 122, the door frame 121 is connected to the car body 110, and the protective net 122 is circumferentially connected to the door frame 121.

[0072] The car body 110 is provided with an entrance 111, through which a worker can enter and exit the car 100, and can perform maintenance, service and control of the stacker in the car 100. A door assembly 120 is installed on the car body 110, and the door assembly 120 can open or close the entrance 111.

[0073] A protective net 122 is installed on the door frame 121. The protective net 122 is located in the enclosed area of ​​the door frame 121. The protective net 122 can prevent the work and goods in the car 100 from falling through the door assembly 120 to the outside of the car 100, thereby preventing tools and goods from causing danger to the staff outside the car 100 and improving the work safety of the staff around the stacker. The protective net 122 is a grid structure, which allows the staff inside and outside the car 100 to understand each other's situation, which is conducive to handling emergency problems. The staff inside the car 100 can quickly inform the staff outside the car 100 of their demands through the protective net 122, thereby improving the safety and communication convenience during the work process.

[0074] Exemplarily, the protective net 122 is made of nylon material, which is light and elastic. In addition to nylon, it can also be made of materials such as steel wire rope.

[0075] Combination Figure 3 and Fig. 9 As shown, in some embodiments, optionally, the door frame 121 has a folded state and an unfolded state. In the folded state, the door body assembly 120 opens the entrance and exit 111, and in the unfolded state, the door body assembly 120 closes the entrance and exit 111, and the protective net 122 can deform with the movement of the door frame 121.

[0076] The door assembly 120 can be switched between a folded state and an unfolded state, so that the door assembly 120 can open or close the entrance 111. Specifically, when the user needs to enter or exit the elevator car 100, the door assembly 120 can be folded so that the door assembly 120 opens the entrance 111. When the entrance 111 needs to be closed, the door assembly 120 is switched to the unfolded state so that the door assembly 120 closes the entrance 111. If the door assembly 120 is an outwardly rotating way to open the entrance 111, when there is an obstacle outside the elevator car 100, it is difficult for the door assembly 120 to open outwards. If the door assembly 120 is an inwardly rotating way to open the entrance 111, when there is a staff member standing in the elevator car 100, the door assembly 120 opened inwards will be interfered by the staff member, and the way of opening outwards or opening outwards takes up more space. The door assembly 120 is arranged to open the entrance and exit 111 in a folding manner. Even if there are obstacles or workers inside or outside the car 100, it will not affect the opening and closing of the door assembly 120. Moreover, the door assembly 120 occupies less space when opening the entrance and exit 111, which is conducive to use in scenarios with limited space.

[0077] The protection net 122 is made of a deformable material. When the door frame 121 is folded, the protection net 122 can also be folded together, thereby preventing the protection net 122 from interfering with the folding process of the door frame 121 .

[0078] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the door frame 121 includes: a plurality of frames 123, the plurality of frames 123 are connected end to end in sequence, the protective net 122 is circumferentially connected to the plurality of frames 123, a frame 123 located on the side of the plurality of frames 123 is connected to the car body 110, and two adjacent frames 123 are rotatably connected so that a portion of the door frame 121 can rise or fall relative to the car body 110.

[0079] A plurality of frames 123 are enclosed to form an annular structure. One frame 123 located at the side of the plurality of frames 123 is fixed on the car body 110 , and two adjacent frames 123 are rotatably connected so that the door frame 121 can be raised or lowered.

[0080] Specifically, when the user pushes the door frame 121 upward, two adjacent frames 123 rotate relative to each other, and except for one frame 123 fixed to the car body 110, the remaining frames 123 rise, so that the multiple frames 123 are gradually folded, thereby opening the entrance 111. On the contrary, when the user stops pushing the door frame 121 upward, the two adjacent frames 123 also rotate relative to each other, and except for one frame 123 fixed to the car body 110, the remaining frames 123 fall, so that the multiple frames 123 are gradually unfolded, thereby closing the entrance 111.

[0081] Taking four frames 123 as an example, when the door frame 121 is in the unfolded state, the four frames 123 enclose a rectangular structure. When the door frame 121 is pushed upward, since one frame 123 is fixed on the car body 110, the other three frames 123 will rise. At this time, the four frames 123 enclose a parallelogram structure. Of course, in other embodiments, the number of frames 123 is not limited to 4, and the door body assembly 120 can also add other support rods and other similar parallelogram structures.

[0082] The door assembly 120 is opened and closed by moving up and down, which can reduce the space occupied by the door assembly 120 when opening and closing. The design of the door assembly 120 that opens and closes up and down can reduce the movement space of the door assembly 120, making the stacker design more compact.

[0083] Exemplarily, two adjacent frames 123 are connected via a rotating shaft.

[0084] like Figure 2 As shown, in some embodiments, optionally, a plurality of hooks 124 are provided on the frame 123 , a plurality of mesh holes 125 are provided on the protective net 122 , and the hooks 124 pass through the mesh holes 125 so that the hooks 124 and the protective net 122 are hooked.

[0085] The protective net 122 can be deformed with the folding of the door frame 121. The protective net 122 is a grid structure, so there are multiple grid holes 125 on the protective net 122. A plurality of hooks 124 are provided on any frame 123, and the hooks 124 can pass through the grid holes 125, so that the protective net 122 can be installed and fixed on the frame 123.

[0086] In a possible application, the number of sides of the protection net 122 is the same as the number of frames 123 , and one side of the protection net 122 is fixed to one frame 123 .

[0087] The protection net 122 is fixed to the frame 123 by means of the hook 124. The installation method of the protection net 122 is relatively simple. Moreover, when the protection net 122 is damaged, it is also convenient to disassemble and replace the protection net 122.

[0088] Exemplarily, the size of the grid holes 125 is 50 mm×50 mm, which can prevent large objects from falling.

[0089] Combination Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the plurality of frames 123 include: a first frame 126 and a second frame 127, the first frame 126 includes a support frame 1261 and a first mounting plate 1262, the support frame 1261 is provided with a receiving groove 1263, the receiving groove 1263 extends along the length direction of the support frame 1261, the first mounting plate 1262 is arranged in the receiving groove 1263, and the first mounting plate 1262 is provided with a hook 124. The second frame 127 includes a supporting plate 1271 and a second mounting plate 1272 connected in sequence, the second mounting plate 1272 is connected to the supporting plate 1271, the end of the supporting plate 1271 extends into the receiving groove 1263 in the adjacent first frame 126, and the second mounting plate 1272 is provided with a hook 124.

[0090] Among the multiple frames 123, there are two types of frames 123. The first frame is the first frame 126 which is a combination of a support frame 1261 and a first mounting plate 1262. A receiving groove 1263 is arranged on the support frame 1261, and the first mounting plate 1262 can be installed in the receiving groove 1263. A hook 124 is arranged on the first mounting plate 1262. When the protective net 122 is connected with the hook 124 on the first mounting plate 1262, a part of the protective net 122 extends into the receiving groove 1263. Therefore, the connection position of the protective net 122 and the first mounting plate 1262 is located in the receiving groove 1263, and it is not easy for staff or external structures to touch the connection position of the protective net 122 and the first mounting plate 1262, thereby preventing the protective net 122 from being scratched and separated from the first mounting plate 1262, thereby ensuring the stable connection between the protective net 122 and the first mounting plate 1262. Compared with the method of directly processing and forming the hook 124 on the inner wall of the receiving groove 1263, the processing method of installing the first mounting plate 1262 with the hook 124 into the receiving groove 1263 is simpler.

[0091] The second frame is a second frame 127 composed of a bearing plate 1271 and a second mounting plate 1272 . A hook 124 is provided on the second mounting plate 1272 , and the protective net 122 is fixed to the second mounting plate 1272 through the hook 124 . Although the accommodating groove 1263 on the support frame 1261 can cover the connection position between the protective net 122 and the first mounting plate 1262, it also increases the difficulty of disassembling the protective net 122. Therefore, a part of the side edge of the protective net 122 can be exposed, that is, a part of the side edge of the protective net 122 is installed on the second mounting plate 1272. When the protective net 122 is disassembled, the protective net 122 can be disassembled to the second mounting plate 1272 first. At this time, the protective net 122 will not be too tight, so it is convenient to disassemble the other side edges of the protective net 122 to the first mounting plate 1262. Similarly, when installing the protective net 122, the protective net 122 can be installed on the first mounting plate 1262 first, and finally a part of the side edge of the protective net 122 is fixed to the second mounting plate 1272. In the above manner, the convenience of disassembly and assembly of the protective net 122 can be improved.

[0092] The separate second mounting plate 1272 is prone to deformation, and the supporting plate 1271 may be used to support the second mounting plate 1272 , thereby preventing the second mounting plate 1272 from being deformed and preventing the protective net 122 from being separated from the second mounting plate 1272 .

[0093] For example, the support frame 1261 and the first mounting plate 1262 can be fixed by welding, or the support frame 1261 and the first mounting plate 1262 are locked to each other by screws. Similarly, the bearing plate 1271 and the second mounting plate 1272 can be fixed by welding, or the bearing plate 1271 and the second mounting plate 1272 are locked to each other by screws.

[0094] like Fig. 9 As shown, in this embodiment, there are three first frames 126, which are named as the first sub-frame 1281, the second sub-frame 1282 and the third sub-frame 1283, wherein the first sub-frame 1281 is located at the top, the second sub-frame 1282 is located at the side, and the third sub-frame 1283 is located at the bottom.

[0095] Combination Figure 2 and Figure 7 As shown, in some embodiments, optionally, the second frame 127 also includes: a fixing plate 1273, the fixing plate 1273 and the supporting plate 1271 are located on both sides of the second mounting plate 1272, a portion of the fixing plate 1273 is bent compared to the second mounting plate 1272, and the bent portion of the fixing plate 1273 is arranged opposite to the opening of the hook 124.

[0096] A fixing plate 1273 and a bearing plate 1271 are connected to both sides of the second mounting plate 1272 . The fixing plate 1273 can further strengthen the structure of the second mounting plate 1272 , thereby preventing the second reinforcing plate from being deformed.

[0097] A portion of the fixing plate 1273 is bent in a direction away from the second mounting plate 1272, so that a portion of the fixing plate 1273 is tilted above the second mounting plate 1272, and the bent portion of the second mounting plate 1272 is opposite to the opening of the hook 124, so that the second mounting plate 1272 can cover the opening of the hook 124, preventing staff or external structures from scratching the connection position between the protective net 122 and the second mounting plate 1272, and preventing the protective net 122 from detaching from the second mounting plate 1272.

[0098] Exemplarily, the fixing plate 1273 is fixed to the first mounting plate 1262 by welding, or the fixing plate 1273 and the first mounting plate 1262 are locked to each other by screws.

[0099] Combination Figure 3 , Figure 4 , Figure 5 and Fig. 9As shown, in some embodiments, optionally, the car 100 also includes: a first supporting seat 130 and a second supporting seat 140, both of which are connected to the car body 110, and in the expanded state, the supporting seat is used to support the frame 123 located at the top among the multiple frames 123, and in the expanded state, the supporting seat is used to support the frame 123 located at the bottom among the multiple frames 123.

[0100] A first supporting seat 130 and a second supporting seat 140 are installed on the car body 110. When the door body assembly 120 is in the unfolded state, the first supporting seat 130 supports the top frame 123, and the second supporting seat 140 supports the bottom frame 123. The first supporting seat 130 and the second supporting seat 140 limit the top frame 123 and the bottom frame 123 to prevent the top frame 123 and the bottom frame 123 from continuing to descend, thereby stably fixing the door body assembly 120 in the position of closing the entrance and exit 111.

[0101] The first supporting seat 130 and the second supporting seat 140 may be fixed to the car body 110 by welding, or the first supporting seat 130 and the second supporting seat 140 may be integrally formed on the car body 110 .

[0102] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, in the expanded state, the first supporting seat 130 and the frame 123 located at the top of the multiple frames 123 are plugged into and limited to each other, and / or the second supporting seat 140 and the frame 123 located at the bottom of the multiple frames 123 are plugged into and limited to each other.

[0103] When the first supporting seat 130 supports the top frame 123, the first supporting seat 130 and the top frame 123 are also plugged into each other. At this time, the first supporting seat 130 can limit the top frame 123 to prevent the top frame 123 from shaking, thereby ensuring that the structure of the door body assembly 120 is not easily damaged. Moreover, by preventing the top frame 123 from shaking, it is also possible to prevent the top frame 123 from detaching from the first supporting seat 130, thereby ensuring that the first supporting seat 130 can stably support the top frame 123.

[0104] Similarly, when the second supporting seat 140 supports the bottom frame 123, the second supporting seat 140 and the bottom frame 123 are also plugged into each other. At this time, the second supporting seat 140 can limit the bottom frame 123 to prevent the bottom frame 123 from shaking, thereby ensuring that the structure of the door body assembly 120 is not easily damaged. Moreover, by preventing the bottom frame 123 from shaking, it is also possible to prevent the bottom frame 123 from detaching from the second supporting seat 140, thereby ensuring that the second supporting seat 140 can stably support the bottom frame 123.

[0105] In a possible application, when the first support seat 130 supports the top frame 123, the first support seat 130 extends into the receiving groove 1263 of the top frame 123. The two sides of the first support seat 130 are wedge-shaped, so that they can cooperate with the receiving groove 1263 of the top frame 123, so that the door body assembly 120 is firmly closed without shaking and noise. The second support seat 140 has a supporting groove, and when the second support seat 140 supports the bottom frame 123, the bottom frame 123 extends into the supporting groove.

[0106] Combination Figure 2 and Figure 3 As shown, in some embodiments, optionally, the car 100 further includes: a door handle 150 , and the door handle 150 is disposed on a frame 123 located at the top among the multiple frames 123 .

[0107] A door handle 150 is installed on the top frame 123 , and the user can apply force to the door handle 150 to lift or pull down the door frame 121 , which is convenient for the staff to operate, thereby making it easier for the staff to fold or unfold the door body assembly 120 .

[0108] By pulling the door handle 150 upward, the door is opened upward. Fig. 9 The effect diagram of the door opening 45° is shown in FIG. 1 , and the maximum angle at which the door opens upward is 90°.

[0109] The door handle 150 can be fixed to the frame 123 by means of fastening members such as screws.

[0110] Combination Figure 2 and Figure 3 As shown, in some embodiments, optionally, a first limiting portion 151 is provided on the door handle 150, and a second limiting portion 160 is provided on the car body 110. In the folded state, the first limiting portion 151 and the second limiting portion 160 are connected, and in the unfolded state, the first limiting portion 151 and the second limiting portion 160 are separated.

[0111] The staff folds the door assembly 120 by lifting the door handle 150. If the door handle 150 is released, the door assembly 120 will automatically unfold under the action of gravity, which causes the user to continue to lift the door handle 150. Therefore, in order to avoid the above situation, a second limiting portion 160 is set on the car body 110. After the door handle 150 is lifted, the first limiting portion 151 and the second limiting portion 160 can be connected. The second limiting portion 160 limits the first limiting portion 151. At this time, the door assembly 120 will not automatically unfold under the action of gravity, and the user can let go to perform other operations, thereby improving the convenience of the staff at work. When the entrance and exit 111 needs to be closed, the first limiting portion 151 is separated from the second limiting portion 160, so that the door assembly 120 can be unfolded.

[0112] Exemplarily, the first limiting part 151 is a groove on the door handle 150, and the second limiting part 160 is a hook, which is rotatably connected to the car body 110. When the door is opened 90°, the hook can be inserted into the groove of the door handle 150 by rotation, which can limit the door frame 121 and prevent the door frame 121 from falling and closing. When the door needs to be closed, the hook can be rotated to disengage it from the groove of the door handle 150, and the door can be closed downward.

[0113] Of course, the first limiting portion 151 and the second limiting portion 160 may also be matched in other structures, for example, by buckling with each other.

[0114] Combination Figure 1 and Figure 3 As shown, in some embodiments, optionally, the car body 110 includes: side panels 112, a bottom panel 113 and a top panel 114, the side panels 112 are connected to the door body assembly 120, the bottom panel 113 is connected to the side panels 112, the bottom panel 113 is located at the bottom of the side panels 112, and the top panel 114 is connected to the side panels 112, and the top panel 114 is located at the top of the side panels 112.

[0115] A top plate 114 and a top plate 114 are respectively provided at the top and bottom of the side plate 112. After the staff enters the car 100, the staff can stand on the top plate 114 to work. At this time, the top plate 114 is located above the staff. The top plate 114 can prevent objects falling from the upper space from hitting the staff, thereby playing a protective role for the staff and helping to improve the safety of the staff at work.

[0116] The manually operated car on the cargo platform 500 can facilitate maintenance personnel to perform maintenance and abnormal operation processing on the stacker, and can provide a safe operating environment to prevent mechanical damage from the surroundings and the top.

[0117] Combination Figure 1 and Figure 3As shown, in some embodiments, optionally, an anti-slip portion 115 is provided on the top of the bottom plate 113 .

[0118] The staff stands on the bottom plate 113 to work in the car 100. An anti-slip portion 115 is provided on the upper surface of the bottom plate 113. The anti-slip portion 115 can increase the friction on the soles of the staff and play an anti-slip function. It is not easy for the staff to slip on the bottom plate 113, which is beneficial to improving the safety of the staff when working in the car 100.

[0119] Exemplarily, the anti-slip portion 115 is a pattern on the top of the bottom plate 113 and has an anti-slip effect.

[0120] like Figure 1 As shown, in some embodiments, optionally, the car 100 further includes: a control panel 170 , and the control panel 170 is connected to the car body 110 .

[0121] The control panel 170 is installed on the car body 110. When the cargo platform 500 of the stacker fails or needs maintenance, the staff can enter the car 100 area and control the stacker to move, the cargo platform 500 to rise and fall, and the fork 400 of the cargo platform 500 to extend and retrieve through the control panel 170.

[0122] The control panel 170 may be in the form of a touch screen control system, a button operation panel, a handheld operator control box, or the like.

[0123] Combination Figure 3 and Figure 6 As shown, in some embodiments, optionally, the car 100 further includes: a door detection component 180 connected to the car body 110 and the door body component 120 , and in the expanded state, the door detection component 180 is used to output a door opening signal to the control panel 170 .

[0124] A door detection assembly 180 is installed on the car body 110 and the door body assembly 120. The door detection assembly 180 is used to detect whether the door body assembly 120 is in an open state. When the door detection assembly 180 detects that the door body assembly 120 is in an open state, the door detection assembly 180 can output a door opening signal to the control panel 170.

[0125] When the staff is entering the car 100, if the stacker is in operation, it may cause harm to the staff. Therefore, the stacker can be controlled to stop running when the staff opens the door to ensure the safety of the staff when entering the car 100. After the staff enters the car 100, the door body assembly 120 is in a closed state. At this time, the door body assembly 120 no longer outputs a door opening signal, and the stacker can be controlled to operate normally.

[0126] Combination Figure 6 and Fig.10 As shown, in some embodiments, optionally, the door detection assembly 180 includes: a detection switch 181 and a trigger member 182, the detection switch 181 is connected to the car body 110, the trigger member 182 is connected to the door body assembly 120, the trigger member 182 can rotate with the door frame 121, in the folded state, the detection switch 181 is separated from the trigger member 182, and in the unfolded state, the detection switch 181 is in contact with the trigger member 182, so that the detection switch 181 outputs a door opening signal.

[0127] When the entrance 111 is opened, two adjacent frames 123 rotate relative to each other, and the trigger 182 is installed on the frame 123. The trigger 182 can move with the frame 123. When the trigger 182 contacts the detection switch 181, the trigger 182 triggers the detection switch 181, and the detection switch 181 outputs a door opening signal. When the door assembly 120 is in a closed state, the trigger 182 is separated from the detection switch 181. At this time, the trigger 182 does not trigger the detection switch 181, and the detection switch 181 no longer outputs a door opening signal. In the above manner, the detection switch 181 can accurately detect whether the door assembly 120 is in an open state, ensuring the safety of the staff at work.

[0128] Combination Figure 6 and Fig.10 As shown, in some embodiments, optionally, the trigger member 182 includes: a cam, the cam having a fan-shaped surface 184, and a groove 185 is provided on the fan-shaped surface 184. In the folded state, the groove 185 is opposite to the detection switch 181, and in the unfolded state, the fan-shaped surface 184 is in contact with the detection switch 181.

[0129] When the groove 185 is set on the fan-shaped surface 184, the radius of the bottom wall of the groove 185 is smaller than the radius of the fan-shaped surface 184. When the groove 185 is opposite to the detection switch 181, the cam is not in contact with the detection switch 181, and the detection switch 181 is not triggered. When the fan-shaped surface 184 is opposite to the detection switch 181, due to the larger radius of the fan-shaped surface 184, the fan-shaped surface 184 is in contact with the detection switch 181, thereby triggering the detection switch 181.

[0130] This embodiment mentions a stacker's manual car 100 and a safety door system. The car 100 can provide a safe environment in all directions to prevent mechanical damage around it. The maintenance operator can conveniently operate the stacker in the car 100, and perform operations such as walking the stacker, lifting the cargo platform 500, and telescopic forks. Due to the design of the safety door (door body assembly 120), it can effectively prevent the maintenance personnel's tools from falling from the manual car 100 to injure the safety of the maintenance personnel below. The opening and closing states of the safety door can be detected by special cams and switches. When the door is opened, the control system blocks the action of the stacker to prevent the sudden action of the stacker from causing accidental injuries to the maintenance personnel.

[0131] The cam is installed on the bottom frame 123 and rotates with the bottom frame 123. The detection switch 181 is installed on the side panel 112 through the switch bracket 183. The detection switch 181 is a roller direct-acting limit switch. When the door is closed, the roller of the roller direct-acting limit switch is in the groove 185 of the cam, and the roller direct-acting limit switch is not triggered. When the door is opened at an angle, the cam rotates with the bottom frame 123, the roller direct-acting limit switch contacts the edge of the cam and is compressed, and the roller direct-acting limit switch is triggered.

[0132] When the door is in a closed state, the roller direct-acting limit switch is not triggered. When the maintenance personnel opens the door, the roller direct-acting limit switch is triggered by the rotating cam, and the roller direct-acting limit switch sends a signal to the control panel 170 of the car 100. The control panel 170 prohibits the operation of the stacker travel drive, the cargo platform 500 lifting drive and the fork 400 telescopic fork to prevent the movement of the stacker from causing harm to the maintenance personnel. When the door is closed, whether the personnel leave the car 100 or are in the car 100, the alarm information is released and the equipment returns to normal and can operate.

[0133] The operator can enter the manual car operating area through the door that opens and closes up and down. After entering, the door body assembly 120 can be lowered and closed. During the opening and closing process of the door body assembly 120, the limit switch detects the opening state of the door body assembly 120 through the rotating cam block and shuts down to prevent the equipment from opening abnormally and causing people to fall, thereby effectively protecting the safety of the operator.

[0134] like Figure 1 As shown, in an embodiment of the utility model, a cargo platform 500 for a stacker is proposed, comprising: a cargo platform body 200, a photoelectric bracket 300, a fork 400 and a car 100 in any of the above embodiments, the photoelectric bracket 300, the fork 400 and the car 100 are all connected to the cargo platform body 200, and the photoelectric bracket 300 is used to output a detection signal for the goods.

[0135] The cargo platform 500 in this embodiment can achieve the technical effects in any of the above embodiments, which will not be elaborated here.

[0136] The fork 400 can be used for picking up or placing goods. A sensor is provided on the photoelectric bracket 300. The photoelectric bracket 300 is used to detect the information of the goods on the fork 400, for example, whether there are goods on the fork 400, the height and specifications of the goods, etc.

[0137] Exemplarily, the cargo platform body 200 may be mounted on a driving structure of a stacker, so that the cargo platform body 200 may be moved driven by the driving structure.

[0138] In some embodiments, optionally, the first side of the car 100 faces the photoelectric support 300 and the fork 400 , and the first side of the car 100 is an open side.

[0139] When the staff needs to maintain the photoelectric bracket 300 and the fork 400, since the first side of the car 100 is an open side, the staff can enter the area where the photoelectric bracket 300 and the fork 400 are located from the first side of the car 100, which is convenient for users to enter the target area for maintenance.

[0140] In an embodiment of the present utility model, a stacker is proposed, including a cargo platform 500 for a stacker as in the above embodiment, and can achieve the same technical effect, which will not be described in detail herein.
