Description

Technical Field

[0001] The invention belongs to the field of column welding, and specifically relates to a device for welding high-speed rail door columns. Background Art

[0002] Existing welding machines are mainly used for welding objects with low height. Even if there is a certain height, usually the device is directly placed at a high place for welding. The height adjustment of the welding machine is generally very limited, resulting in the need to build a platform with inconvenient height adjustment for workers or welding machines to carry out welding, which is very inconvenient and time-consuming. Especially when welding high-speed rail door columns, since the space where the high-speed rail door columns are located is often restricted and narrow, if temporary repairs are carried out, the construction period will be greatly delayed. Therefore, a device for welding high-speed rail door columns is proposed. Summary of the Invention

[0003] The purpose of this part is to outline some aspects of the embodiments of the invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the specification of this application, to avoid obscuring the purpose of this part, the abstract, and the title of the invention. However, such simplifications or omissions shall not be used to limit the scope of the invention.

[0004] In view of the following technical problems existing in the prior art: existing welding machines are mainly used for welding objects with low height. Even if there is a certain height, usually the device is directly placed at a high place for welding. The height adjustment of the welding machine is generally very limited, resulting in the need to build a platform with inconvenient height adjustment for workers or welding machines to carry out welding, which is very inconvenient and time-consuming.

[0005] To solve the above technical problems, the invention provides the following technical solutions: a device for welding high-speed rail door columns, including a bearing frame, a locking frame one, a locking frame two, and a coupling component;

[0006] The bearing frame is a constraint mechanism. The lower edge of the bearing frame is installed on a mobile device, and a constraint plate is installed on the bearing frame. The number of the constraint plates is more than two.

[0007] A welding machine is installed on the locking frame one. The locking frame one is movably connected to the bearing frame. A hook is installed on the locking frame one. The hook is movably hung on the constraint plate, which can prevent the locking frame one from falling quickly.

[0008] The hook can only rotate unidirectionally. When the locking frame one moves downward, it is blocked by the bearing frame.

[0009] One side of the electric cylinder is installed with the locking frame two, and the other side of the electric cylinder is installed with the coupling component. The electric cylinder can control the movement of the locking frame two; the electric cylinder includes an electric cylinder.

[0010] The welding machine is installed on the locking frame one or the locking frame two.

[0011] The locking frame two includes a second support plate, a first movable restraint block and a second movable restraint block. The first movable restraint block and the second movable restraint block are rotatably connected to the second support plate. The first movable restraint block is below the second movable restraint block. Both the first movable restraint block and the second movable restraint block have an operating posture and a retracted posture.

[0012] Operating posture: The second movable restraint block is latched with the restraint plate or the first movable restraint block is latched with the restraint plate. Retracted posture: The second movable restraint block is separated from the restraint plate or the first movable restraint block is separated from the restraint plate.

[0013] The connecting assembly includes a fourth support plate and a third movable restraint block. The first locking frame is connected to the fourth support plate, and the third movable restraint block is variably connected to the fourth support plate. The third movable restraint block also includes an operating posture and a retracted posture. Operating posture: The third movable restraint block is latched with the restraint plate. Retracted posture: The third movable restraint block is separated from the restraint plate.

[0014] Operating mechanism: When the first locking frame moves upward: The first movable restraint block is adjusted to the retracted posture, the second movable restraint block is adjusted to the operating posture, and the first spring is adjusted to the retracted posture; The electric cylinder starts, and the electric cylinder extends to control the first locking frame to move upward. The second movable restraint block contacts and locks with the restraint plate, and the relative movement between the first locking frame and the bearing frame can be adjusted. During this period, the restraint plate can force the hook to swing until the hook reaches the other side of the restraint plate from one side of the restraint plate, and then the hook returns to its original posture. The function of quickly returning the hook to its original position can be achieved by setting a torsion spring.

[0015] When the electric cylinder shortens, the restraint plate is reconnected to the hook, and the first locking frame moves a certain distance accordingly. During the shortening of the electric cylinder, the second movable restraint block contacts the restraint plate to make the restraint plate swing, and the second movable restraint block returns through the restraint plate.

[0016] The relative position between the first locking frame and the bearing frame can also be locked, and the movement of the second locking frame relative to the bearing frame can be controlled.

[0017] For example: When the second locking frame moves downward: The first movable restraint block is adjusted to the operating posture, the second movable restraint block is adjusted to the retracted posture, and the third movable restraint block is adjusted to the operating posture; Control the electric cylinder to extend, the second locking frame moves downward, the first movable restraint block contacts the restraint plate and swings through the restraint plate, and then the first movable restraint block becomes the operating posture again; When the electric cylinder shortens, the second movable restraint block is latched with the restraint plate.

[0018] After the second locking frame is latched with the restraint plate, the locking between the connecting assembly and the first locking frame is released, and the connecting assembly is separated from the first locking frame; Subsequently, when the electric cylinder shortens, during the movement of the connecting assembly, the electric cylinder drives the first spring to deflect through the restraint plate and then returns to the operating posture, and the electric cylinder controls the first spring to contact the restraint plate.

[0019] The movable constraint block two is adjusted to the operating posture. When controlling the operation of the electric cylinder, it either drives the connecting component and the locking frame one to move, or moves the locking frame two. The whole process is highly controllable, greatly reducing the labor cost and significantly improving the safety.

[0020] The length change of the electric cylinder is along the vertical direction.

[0021] The bearing frame includes side beams and accessories of the side beams. The number of the side beams is 2. The side beams are arranged on both sides of the constraint plate, and the side beams are recessed with movable grooves;

[0022] The locking frame one is movably connected to the side beam, and the locking frame two and the connecting component are movably connected to the side beam.

[0023] The side beam is fixedly connected to the constraint plate.

[0024] The locking frame one includes a support plate one, and a rotating cylinder one is arranged on the support plate one. The rotating cylinder one is movably connected to the movable groove. ;

[0025] Support plates one are arranged on both sides of the locking frame one, and a rotating cylinder one is arranged on the support plate one. The rotating cylinder one on the support plate one matches the movable groove. Constraint pieces are arranged on the side beam, and constraint pieces are arranged on all the side beams. The constraint pieces are close to and move out of the constraint pieces.

[0026] A limiting platform one is arranged on the support plate two. The limiting platform one is movably connected to the constraint piece, and a matching groove one is reserved on the limiting platform one. The matching groove one is connected to the constraint piece, so that the locking frame two is constrained to be always connected to the bearing frame.

[0027] A limiting platform two is arranged on the support plate four. The limiting platform two is movably connected to the constraint piece, and a matching groove two is reserved on the limiting platform two. The matching groove two is connected to the constraint piece to ensure that the connecting component is kept connected to the bearing frame.

[0028] The locking frame two further includes a spring two, and the spring two connects the movable constraint block one and the movable constraint block two.

[0029] The spring two can make the movable constraint block one and the movable constraint block two change to the operating posture or the retracted posture.

[0030] During the shortening of the electric cylinder, the movable constraint block two of the locking frame two will deflect when it encounters the constraint plate, and after the movable constraint block two passes through the constraint plate, it will be driven by the spring two to return to the original posture.

[0031] When the electric cylinder extends, the movable constraint block one contacts the constraint plate and deflects to bypass the constraint plate. After the movable constraint block one passes through the constraint plate, the spring two drives the movable constraint block one to return to the original operating posture.

[0032] When the electric cylinder shortens, the movable constraint block one thus latches onto the constraint plate.

[0033] The locking bracket two is connected, and the connecting component can be disconnected from the locking bracket one. An electromagnet is installed inside the locking bracket one. When the electromagnet is activated, the connecting component can be fixed to the locking bracket one.

[0034] The electric cylinder shortens, and the connecting component moves close to the locking bracket two. The movable restraint block three deflects when it encounters the restraint plate and bypasses the restraint plate. After passing the restraint plate, the spring two drives the movable restraint block three back to its operating position.

[0035] The movable restraint block one is equipped with a toggling frame two. The toggling frame two is connected to the spring two. The support plate two is variably installed with a locking rod one. The way the movable restraint block one adjusts to the retracted position: The toggling frame one is connected to the locking rod one, and the locking rod one blocks the toggling frame one. During the separation of the locking rod one from the toggling frame one, the potential energy of the spring two is released, and the movable restraint block one switches from the retracted position to the operating position.

[0036] Control the movement of the toggling frame one to deflect the movable restraint block one, so that the movable restraint block one can switch back and forth between the retracted position and the operating position.

[0037] During the deflection of the movable restraint block one to the retracted position, control the toggling frame one to the position where it is blocked by the toggled frame one, so that the movable restraint block one maintains the retracted position. Pull the movable restraint block one to the movable restraint block one, pull out the locking rod one, so that the locking rod one is separated from the toggling frame one. The toggling frame one releases potential energy to deflect the movable restraint block one to the operating position. The locking rod one includes a locking nail. The movable restraint block two is equipped with a toggling frame two. The toggling frame two is connected to the spring two. The support plate two is connected to the locking rod two. During the maintenance of the retracted position of the movable restraint block two, it blocks the toggling frame two. The spring two pulls the toggling frame two. After separating from the toggling frame two, the spring two pulls the movable restraint block two to deflect to the operating position. Control the toggling frame one to deflect the movable restraint block one, so that the movable restraint block one can switch back and forth between the retracted position and the operating position.

[0038] During the deflection of the movable restraint block two to the retracted position, control the toggling frame two to be blocked by the locking rod two, and the movable restraint block two will adjust to the retracted position. The toggling frame two continuously resists the pulling force of the spring two. Pull the locking rod two to separate the locking rod two from the toggling frame two. The spring two releases potential energy to pull the movable restraint block two to adjust to the operating position. The locking rod two includes a locking nail.

[0039] The locking frame 2 also includes a constraint frame 2, and a movable constraint block 1 is installed on one side of the constraint frame 2, and a movable constraint block 2 is installed on the other side of the constraint frame 2. The movable constraint block 1 is adjusted to an operating posture, and the movable constraint block 1 contacts the constraint frame 2. The movable constraint block 2 is adjusted to an operating posture, and the movable constraint block 2 is squeezed with the constraint frame 2, and the constraint frame 2 blocks the movable constraint block 1 and the movable constraint block 2 from changing their postures. The constraint frame 2 constrains the movable constraint block 1 and the movable constraint block 2 to deflect in only one direction, and the movable constraint block 1 and the movable constraint block 2 can only change from the operating posture to the retreat posture, so that the movable constraint block 1 and the movable constraint block 2 firmly lock the constraint plate.

[0040] The movable constraint block three is connected, and the connecting component includes a spring one. One side of the spring one is connected to the pulling frame three, and one side of the spring one is connected to the support plate four. The support plate four is movably connected to the locking rod three. The movable constraint block three is adjusted to a retreat posture, the pulling frame three and the locking rod three compress the spring one, and the locking rod three is separated from the pulling frame three. The movable constraint block three is driven by the spring one to change from the retreat posture to the operating posture.

[0041] In order to adjust the movable restraint block 3 to the retreat posture, the pull frame 3 blocks the pressure of the spring 1. In order to adjust the movable restraint block 2 to the operating posture, the locking rod 3 can be taken out, so that the locking rod 3 is separated from the pull frame 3, and the pull frame 3 is pushed by the spring 1 to convert the movable restraint block 3 into the operating posture. The locking rod 3 includes a locking nail.

[0042] The support plate 4 is movably connected to the constraint frame 3, the movable constraint block 3 is adjusted to the operating posture, and the movable constraint block 3 is in contact with the constraint frame 3. The constraint frame 3 can block the deflection of the movable constraint block 3 in one direction, so that the movable constraint block 3 can only deflect, and the posture of the movable constraint block 3 can only be converted from the operating posture to the retreat posture, so that the movable constraint block 3 is firmly buckled with the constraint plate.

[0043] The first restraint frame is arranged on a side of the second locking frame close to the hook, and the restraint frame contacts the hook together, so that the hook can only deflect in one direction.

[0044] A restraining frame 1 is arranged on one side of the hook close to the locking frame 2, the hook can only be deflected toward the low position, and the hook is movably connected with the restraining plate so that the locking frame 1 and the bearing frame will not move relative to each other.

[0045] The movable constraint block 2 is adjusted to the operating posture. When the electric cylinder is controlled to operate, it moves with the locking frame 2. The whole height is controllable, which greatly reduces labor costs and greatly improves safety.

[0046] The active constraint block 1 is adjusted to the operating posture, the active constraint block 2 is adjusted to the retreat posture, and the active constraint block 3 is in the operating posture. The electric cylinder controls the movement of the locking frame 2 or the connecting component. The active constraint block 1 and the active constraint block 3 are blocked by the constraint plate, so that the movement of the electric cylinder can be controlled.

[0047] A welding machine is installed on the second locking bracket or the first locking bracket. The welding machine includes a chassis, a first motor, a first control arm, a second control arm, a welding head and a receiving table. The chassis is connected to the second locking bracket or the first locking bracket. The first motor is installed on the receiving table, and the power output end of the first motor is connected to the chassis. The second motor is installed on the receiving table, and the power output end of the second motor is connected to the first control arm. The third motor is connected to the first control arm, and the power output end of the third motor is connected to the second control arm. The fourth motor is installed on the second control arm, and the power output end of the fourth motor is installed with the welding head.

[0048] The beneficial effects of the device for welding the high-speed rail door column of the present invention: By using the electric cylinder, the coupling component, the bearing frame, the second locking bracket and the first locking bracket, the height of the welding machine can be flexibly controlled and adjusted, so that the welding machine can flexibly move on a relatively high vertical plane, so as to quickly weld on the column. Moreover, the electric cylinder, the bearing frame and the first locking bracket occupy a small space, which is convenient for operation in a narrow space. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Next, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0068] As Figures 1 to 13 shown, the present invention provides a device for welding high-speed rail door columns, including a carrier 200, a first locking frame 300, a second locking frame 500, a coupling assembly 600, and;

[0069] The carrier 200 is a constraint mechanism. The lower part of the carrier 200 is installed on a mobile device. A constraint plate 202 is installed on the carrier 200, and the number of the constraint plates 202 is more than two.

[0070] A welding machine is installed on the first locking frame 300. The first locking frame 300 is movably connected to the carrier 200. A hook 303 is installed on the first locking frame 300, and the hook 303 is movably hooked to the constraint plate 202, which can make it difficult for the first locking frame 300 to fall quickly.

[0071] The hook 303 can only rotate unidirectionally, and the first locking frame 300 is blocked by the carrier 200 when moving downward.

[0072] A second locking frame 500 is installed on one side of the electric cylinder 100, and a coupling assembly 600 is installed on the other side of the electric cylinder 100. The electric cylinder 100 can control the movement of the second locking frame 500; the electric cylinder 100 includes an electric cylinder.

[0073] The welding machine 700 is installed on the first locking frame 300 or the second locking frame 500.

[0074] The second locking frame 500 includes a second support plate 502, a first movable restraint block 503, and a second movable restraint block 504. The first movable restraint block 503 and the second movable restraint block 504 are rotatably connected to the second support plate 502. The first movable restraint block 503 is below the second movable restraint block 504. Both the first movable restraint block 503 and the second movable restraint block 504 have an operating posture and a retracted posture;

[0075] Operating posture of the first movable restraint block 503: The second movable restraint block 504 is latched to the constraint plate 202 or the first movable restraint block 503 is latched to the constraint plate 202. Retracted posture: The second movable restraint block 504 is separated from the constraint plate 202 or the first movable restraint block 503 is separated from the constraint plate 202.

[0076] The coupling component 600 includes the support plate four 602 and the movable restraint block three 603. The locking frame one 300 is connected to the support plate four 602, and the movable restraint block three 603 is variably connected to the support plate four 602. The movable restraint block three 603 also includes an operating posture and a retracted posture. Operating posture: The movable restraint block three 603 is latched with the restraint plate 202. Retracted posture: The movable restraint block three 603 is separated from the restraint plate 202.

[0077] Operating mechanism: When the locking frame one 300 moves upward: The movable restraint block one 503 is adjusted to the retracted posture, the movable restraint block two 504 is adjusted to the operating posture, and the spring one 604 is adjusted to the retracted posture; The electric cylinder 100 is started, and the electric cylinder 100 elongates to control the locking frame one 300 to move upward. The movable restraint block two 504 contacts and locks with the restraint plate 202, and the relative movement between the locking frame one 300 and the carrier frame 200 can be adjusted. During this period, the restraint plate 202 can force the hook 303 to swing until the hook 303 reaches the other side of the restraint plate 202 from one side of the restraint plate 202, and then the hook 303 returns to its original posture. The function of quickly returning the hook 303 to its original position can be achieved by setting a torsion spring.

[0078] When the electric cylinder 100 shortens, the restraint plate 202 is reconnected to the hook 303, and the locking frame one 300 moves a certain distance accordingly. During the shortening of the electric cylinder 100, the movable restraint block two 504 contacts the restraint plate 202 to cause the restraint plate 202 to swing, and the movable restraint block two 504 returns to its original position after passing through the restraint plate 202.

[0079] The relative position between the locking frame one 300 and the carrier frame 200 can also be locked, and the movement of the locking frame two 500 relative to the carrier frame 200 can be controlled.

[0080] For example: When the locking frame two 500 moves downward: The movable restraint block one 503 is adjusted to the operating posture, the movable restraint block two 504 is adjusted to the retracted posture, and the movable restraint block three 603 is adjusted to the operating posture; Control the electric cylinder 100 to elongate, the locking frame two 500 moves downward, the movable restraint block one 503 contacts the restraint plate 202 and swings through the restraint plate 202, and then the movable restraint block one 503 becomes the operating posture again; When the electric cylinder 100 shortens, the movable restraint block two 504 is latched with the restraint plate 202.

[0081] After the locking frame two 500 is latched with the restraint plate 202, the lock between the coupling component 600 and the locking frame one 300 is released, and the coupling component 600 is separated from the locking frame one 300; Subsequently, when the electric cylinder 100 shortens, during the movement of the coupling component 600, the electric cylinder 100 drives the spring one 604 to deflect through the restraint plate 202, and then returns to the operating posture, and the electric cylinder 100 controls the spring one 604 to contact the restraint plate 202.

[0082] The movable restraint block two 504 is adjusted to the operating posture. When controlling the operation of the electric cylinder 100, it either drives the connecting component 600 and the locking frame one 300 to move, or moves the locking frame two 500. The height is controllable throughout the process, greatly reducing the labor cost and significantly improving the safety.

[0083] The length change of the electric cylinder 100 is along the vertical direction.

[0084] The carrier 200 includes side beams 203 and accessories of the side beams 203. The number of the side beams 203 is two, and the side beams 203 are arranged on both sides of the restraint plate 202. The side beams 203 are recessed with movable grooves 2022;

[0085] The locking frame one 300 is movably connected to the side beam 203, and the locking frame two 500 and the connecting component 600 are movably connected to the side beam 203.

[0086] The side beam 203 is fixedly connected to the restraint plate 202.

[0087] The locking frame one 300 includes a support plate one 302, and a rotating cylinder one 3012 is arranged on the support plate one 302. The rotating cylinder one 3012 is movably connected to the movable groove 2022. ;

[0088] Support plates one 302 are arranged on both sides of the locking frame one 300, and a rotating cylinder one 3012 is arranged on the support plate one 302. The rotating cylinder one 3012 on the support plate one 302 matches the movable groove 2022. Restraint pieces 204 are arranged on the side beam 203. Restraint pieces 204 are arranged on the side beam 203, and the restraint pieces 204 are close to and move out of the restraint pieces 204.

[0089] The support plate two 502 is provided with a limit platform one 5014. The limit platform one 5014 is movably connected to the restraint piece 204, and a mating groove one is reserved on the limit platform one 5014. The mating groove one is connected to the restraint piece 204, so that the locking frame two 500 is constrained to be always connected to the carrier 200.

[0090] The support plate four 602 is provided with a limit platform two 6013. The limit platform two 6013 is movably connected to the restraint piece 204, and a mating groove two is reserved on the limit platform two 6013. The mating groove two is connected to the restraint piece 204 to ensure that the connecting component 600 is kept connected to the carrier 200.

[0091] The locking frame two 500 further includes a spring two 505, and the spring two 505 connects the movable restraint block one 503 and the movable restraint block two 504.

[0092] The spring two 505 can change the movable restraint block one 503 and the movable restraint block two 504 into the operating posture or the retracted posture.

[0093] During the shortening of the electric cylinder 100, the moving restraint block two 504 of the locking frame two 500 will deflect when it encounters the restraint plate 202, and after the moving restraint block two 504 passes through the restraint plate 202, it will be driven back to its original posture by the spring two 505.

[0094] When the electric cylinder 100 extends, the moving restraint block one 503 contacts the restraint plate 202 and deflects to bypass the restraint plate 202. After the moving restraint block one 503 passes through the restraint plate 202, the spring two 505 drives the moving restraint block one 503 back to its original operating posture.

[0095] When the electric cylinder 100 shortens, the moving restraint block one 503 is thus latched to the restraint plate 202.

[0096] The locking frame two 500 is latched to 11, the coupling assembly 600 can be disconnected from the locking frame one 300, and an electromagnet is installed in the locking frame one 300. When the electromagnet is activated, the coupling assembly 600 can be fixed to the locking frame one 300.

[0097] When the electric cylinder 100 shortens, the coupling assembly 600 moves close to the locking frame two 500. The moving restraint block three 603 deflects when it encounters the restraint plate 202 and bypasses the restraint plate 202. After passing through the restraint plate 202, the spring two 505 drives the moving restraint block three 603 back to its operating posture.

[0098] The moving restraint block one 503 is provided with a toggling frame two 5032, the toggling frame two 5032 is hooked with the spring two 505, and the support plate two 502 is variably provided with a locking rod one 5012. The way for the moving restraint block one 503 to adjust to the retracted posture:

[0099] The toggling frame one 5022 is connected to the locking rod one 5012, the locking rod one 5012 blocks the toggling frame one 5022. During the separation of the locking rod one 5012 from the toggling frame one 5022, the potential energy of the spring two 505 is released, and the moving restraint block one 503 switches from the retracted posture to the operating posture.

[0100] Control the movement of the toggling frame one 5022 to deflect the moving restraint block one 503, so that the moving restraint block one 503 can switch back and forth between the retracted posture and the operating posture.

[0101] During the deflection of the movable restraint block 1 (503) to the retracted position, the control lever 1 (5022) is controlled to the position blocked by the levered frame 1 (5022), so that the movable restraint block 1 (503) maintains the retracted position. The movable restraint block 1 (503) is turned to the movable restraint block 1 (503), and the locking rod 1 (5012) is pulled out to separate the locking rod 1 (5012) from the lever 1 (5022). The lever 1 (5022) releases potential energy to deflect the movable restraint block 1 (503) to the operating position. The locking rod 1 (5012) includes a locking pin. The movable restraint block 2 (504) is provided with a lever 2 (5032). The lever 2 (5032) is connected to the spring 2 (505). The support plate 2 (502) is connected to the locking rod 2 (5013). During the period when the movable restraint block 2 (504) maintains the retracted position, 5023 blocks the lever 2 (5032). The spring 2 (505) pulls the lever 2 (5032). After 5023 is separated from the lever 2 (5032), the spring 2 (505) pulls the movable restraint block 2 (504) to deflect to the operating position.

[0102] The control lever 1 (5022) is manipulated to deflect the movable restraint block 1 (503), so that the movable restraint block 1 (503) can be switched back and forth between the retracted position and the operating position.

[0103] During the deflection of the movable restraint block 2 (504) to the retracted position, the control lever 2 (5032) is blocked by the locking rod 2 (5013). The movable restraint block 2 (504) will be adjusted to the retracted position, and the lever 2 (5032) continuously resists the pulling force of the spring 2 (505). The locking rod 2 (5013) is pulled to separate the locking rod 2 (5013) from the lever 2 (5032). The spring 2 (505) releases potential energy to pull the movable restraint block 2 (504) to adjust to the operating position. The locking rod 2 (5013) includes a locking pin.

[0104] The locking frame 2 (500) further includes a restraint frame 2 (506). One side of the restraint frame 2 (506) is provided with the movable restraint block 1 (503), and the other side of the restraint frame 2 (506) is provided with the movable restraint block 2 (504). When the movable restraint block 1 (503) is adjusted to the operating position, the movable restraint block 1 (503) contacts the restraint frame 2 (506). When the movable restraint block 2 (504) is adjusted to the operating position, the movable restraint block 2 (504) presses against the restraint frame 2 (506). The restraint frame 2 (506) blocks the movable restraint block 1 (503) and the movable restraint block 2 (504) from changing their positions. The restraint frame 2 (506) restricts the movable restraint block 1 (503) and the movable restraint block 2 (504) to deflect only in one direction. The movable restraint block 1 (503) and the movable restraint block 2 (504) can only change from the operating position to the retracted position, so that the movable restraint block 1 (503) and the movable restraint block 2 (504) firmly lock the restraint plate 202.

[0105] The movable restraint block three 603 is connected to 6032. The coupling assembly 600 includes a first spring 604. One side of the first spring 604 is connected to the lever frame three 6022, and one side of the first spring 604 is connected to the support plate four 602. The support plate four 602 is movably connected to the locking rod three 6012. The movable restraint block three 603 is adjusted to a retracted posture. The lever frame three 6022 and the locking rod three 6012 compress the first spring 604. The locking rod three 6012 is separated from the lever frame three 6022. The movable restraint block three 603 is driven by the first spring 604 to change from the retracted posture to the operating posture.

[0106] To adjust the movable restraint block three 603 to the retracted posture, the lever frame three 6022 blocks the pressure of the first spring 604. To adjust the movable restraint block two 504 to the operating posture, the locking rod three 6012 can be taken out, so that the locking rod three 6012 is separated from the lever frame three 6022. The lever frame three 6022 is pushed by the first spring 604 to convert the movable restraint block three 603 to the operating posture. The locking rod three 6012 includes a locking nail.

[0107] The support plate four 602 is variably connected to the restraint frame three 605. The movable restraint block three 603 is adjusted to the operating posture, and the movable restraint block three 603 contacts the restraint frame three 605. The restraint frame three 605 can block the deflection of the movable restraint block three 603 in one direction, so that the movable restraint block three 603 can only deflect. The posture of the movable restraint block three 603 can only be converted from the operating posture to the retracted posture, so that the movable restraint block three 603 is firmly fastened to the restraint plate 202.

[0108] The restraint frame one 304 is arranged on one side of the locking frame two 500 close to the hook 303. The restraint frame one 304 contacts the hook 303, so that the hook 303 can only deflect in one direction.

[0109] The restraint frame one 304 is arranged on one side of the hook 303 close to the locking frame two 500. The hook 303 can only deflect downward. The hook 303 is movably hung on the restraint plate 202, so that the locking frame one 300 and the carrier frame 200 will not move relative to each other.

[0110] The movable restraint block two 504 is adjusted to the operating posture. When the control electric cylinder 100 operates, it drives the locking frame two 500 to move. The whole process height is controllable, greatly reducing the labor cost and greatly improving the safety.

[0111] When the movable restraint block one 503 is adjusted to the operating posture, the movable restraint block two 504 is adjusted to the retracted posture, and the movable restraint block three 603 is in the operating posture, the electric cylinder 100 controls the movement of the locking frame two 500 or the coupling assembly 600. Both the movable restraint block one 503 and the movable restraint block three 603 are blocked by the restraint plate 202, so that the movement of the electric cylinder 100 can be controlled.
