Description

Technical Field

[0001] This utility model belongs to the field of intelligent manufacturing technology, and in particular relates to a safety protection device and workstation. Background Technology

[0002] With the improvement of intelligent manufacturing, intelligent gantry cranes, welding devices, and other working mechanisms are widely used. Generally, the movement of the gantry crane is used to achieve automatic cutting, automatic grinding, automatic welding, automatic inspection, and so on. However, during the operation of gantry cranes and other working mechanisms, it is generally necessary to manually observe whether there are any operators in the work area. If no one is present, the gantry crane starts working; after the gantry crane completes its work, it stops, and manual assistance processes begin; the operator climbs onto the workbench to perform the work, and after completing the work, the operator leaves the workbench and moves away from the gantry crane work area.

[0003] Currently, some operations involving gantry cranes still require manual intervention, preventing fully automated operation. When manual intervention is involved, workers must cross the tracks to reach the gantry's work platform, posing significant safety hazards such as missteps, tripping, and collisions with the gantry. Furthermore, it increases the risk of personnel entering the work area while the gantry is in operation, creating substantial safety risks. Utility Model Content

[0004] The main purpose of this utility model is to propose a safety protection device and workstation, which aims to solve the technical problem of large safety hazards in the operation of existing working mechanisms.

[0005] To achieve the above objectives, this utility model provides a safety protection device, comprising: a ground rail, which is sunk to the ground via a sinkhole, the top of which has an opening for a column of a working mechanism to extend into, the column being movably mounted on the top of the ground rail and capable of reciprocating along the ground rail; and a mechanical protection mechanism, comprising at least one protective plate and a flipping drive, the flipping drive being used to drive the protective plate to reciprocate between a protective position and a pedal position, wherein the protective plate in the protective position protrudes from the ground and at least partially covers the opening, while the protective plate in the pedal position allows at least partially covering the opening.

[0006] In this embodiment of the invention, the safety protection device further includes a safety light curtain, which encloses a working area that accommodates the working mechanism and the ground track. The safety light curtain is used to sense personnel entering the area when the working mechanism is in operation.

[0007] In this embodiment of the utility model, the safety protection device further includes a controller. The safety light curtain and the working mechanism are both electrically connected to the controller. The controller is used to shut down the working mechanism when the working mechanism is in working state and the safety light curtain senses personnel.

[0008] In this embodiment of the utility model, the safety light grating includes two grating uprights arranged opposite each other along the X direction, the two grating uprights forming the working area, and the first and last ends of the grating uprights are flush with the first and last ends of the ground rail.

[0009] In this embodiment of the utility model, the first and last ends of the protective plate are flush with the first and last ends of the ground rail, and the protective plate is provided with a limiting groove for limiting the working mechanism.

[0010] In this embodiment of the utility model, there are two columns, which are arranged opposite each other along the X direction. Each column is provided with a mechanical protection mechanism, and the two columns are located between the two mechanical protection mechanisms.

[0011] In this embodiment of the invention, the protective plate is hinged to the flipping drive via a hinge frame, and the hinge frame is located on the side of the flipping drive away from the column.

[0012] In this embodiment of the utility model, the top of the sinking trough is provided with a stepped portion that limits and supports the protective plate, so that the top of the protective plate located at the pedal position is flush with the top of the sinking trough; and / or, the bottom of the protective plate is provided with reinforcing ribs.

[0013] In this embodiment of the utility model, the flipping drive is used to drive the protective plate to flip between zero degrees and ninety degrees, so that the protective plate in the protective position is perpendicular to the ground; and / or, the flipping drive is one of a lifting cylinder, a hydraulic cylinder or an electric cylinder.

[0014] This utility model also proposes a workstation, which includes a working mechanism and the safety protection device described above.

[0015] Through the above technical solution, the safety protection device provided by this utility model embodiment has the following beneficial effects: The safety protection device is mainly used for safety protection when the working mechanism is in operation. When the working mechanism is in operation, the protective plate can be rotated from the pedal position to the protective position by a flip-drive mechanism, causing the protective plate to protrude above the ground and at least partially uncover the opening. The protective plate, located outside the column and protruding above the ground, acts as a fence to prevent personnel from entering the working area of ​​the working mechanism. The uncovered opening further prevents personnel from entering the working area, eliminating safety hazards during operation. When the working mechanism is not in operation, the flip-drive mechanism can drive the protective plate back to the pedal position. In the pedal position, the protective plate completely covers the opening. The protective plate can also act as a pedal, covering the ground rail and the recessed groove. During manual operation, personnel can enter the working area by stepping on the protective plate. This invention uses a recessed groove in the ground to accommodate the ground rail and the flip-drive mechanism. The flip-drive mechanism drives the protective plate, making the protective plate both a pedal and a mechanical fence to protect the working mechanism. This eliminates safety hazards while facilitating operator operation.

[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0017] The accompanying drawings are provided to illustrate the present invention and form part of the specification. They are used together with the following detailed description to explain the present invention, but do not constitute a limitation thereof. In the drawings: Figure 1 This is a structural schematic diagram of a safety protection device according to an embodiment of the present invention.

[0018] Explanation of reference numerals in the attached figures Detailed Implementation

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] The safety protection device according to this utility model is described below with reference to the accompanying drawings.

[0021] like Figure 1As shown, in an embodiment of this utility model, a safety protection device 100 is provided, comprising: a ground rail 2, which is sunk to the ground via a sinkhole 1, the top of the sinkhole 1 having an opening into which the column 210 of the working mechanism 200 extends, the column 210 being movably disposed on the top of the ground rail 2 and capable of reciprocating along the ground rail 2; and a mechanical protection mechanism 3, comprising at least one protective plate 31 and a flipping drive 32, the flipping drive 32 being used to drive the protective plate 31 to reciprocate between a protective position and a pedal position, the protective plate 31 in the protective position protruding from the ground and at least partially uncovering the opening, and the protective plate 31 in the pedal position being capable of at least partially covering the opening.

[0022] In one embodiment, the flipping drive 32 may be installed inside the sink trough 1. In another embodiment, the flipping drive 32 may be installed outside the sink trough 1. In other embodiments, the flipping drive 32 may be installed at other positions that can drive the protective plate 31 to flip back and forth between the protective position and the pedal position.

[0023] Understandably, the working mechanism 200 in this embodiment is mainly used for automatic cutting, automatic grinding, automatic welding, automatic inspection, etc. The working mechanism 200 can be a gantry frame, and there can be one or more protective plates 31. The number of flipping drive components 32 and protective plates 31 are the same and they are connected in a one-to-one correspondence. When there are multiple protective plates 31, all of the multiple protective plates 31 can be located in the protective position, or all of the multiple protective plates 31 can be located in the pedal position, or some of the multiple protective plates 31 can be located in the protective position and the rest of the protective plates 31 can be located in the pedal position.

[0024] In this embodiment, the safety protection device 100 is mainly used for safety protection of the working mechanism 200 in the start-up state. When the working mechanism 200 is in the start-up state, the protective plate 31 can be rotated from the pedal position to the protective position by the flipping drive 32, so that the protective plate 31 protrudes from the ground and the opening is at least partially uncovered. The protective plate 31 is located outside the column 210 and protrudes from the ground, which can be used as a fence to prevent personnel from entering the working area where the working mechanism 200 is located. The opening is at least partially uncovered, which can further prevent personnel from entering the working area where the working mechanism 200 is located, and can eliminate safety hazards during the operation of the working mechanism 200. When the working mechanism 200 is not in operation, the flipping drive 32 can drive the protective plate 31 to return to the pedal position. The protective plate 31 in the pedal position can cover the opening at least partially. The protective plate 31 can be used as a pedal to cover the ground rail 2 and the sinkhole 1. When working manually, one can enter the working area where the working mechanism 200 is located by stepping on the protective plate 31. In this embodiment, the ground track 2 and the flipping drive 32 are accommodated by the sinking groove 1 that is sunken into the ground. The flipping drive 32 drives the protective plate 31, so that the protective plate 31 can be used as a foot pedal and as a mechanical fence. The mechanical protection mechanism 3 protects the working mechanism 200, which can eliminate safety hazards and facilitate the operator to operate the working mechanism 200.

[0025] In one embodiment, the safety protection device 100 further includes a safety light curtain 4, which encloses a working area accommodating the working mechanism 200 and the ground rail 2. The safety light curtain 4 is used to sense personnel entering the area when the working mechanism 200 is in operation. In this embodiment, the safety light curtain 4 is positioned around the perimeter of the working area. When the working mechanism 200 is operating, personnel can be sensed by the safety light curtain 4. If the light curtain senses personnel entering, the working mechanism 200 stops operating, ensuring personnel safety and preventing personnel from entering the working area while the working mechanism 200 is in operation. The mechanical protection mechanism 3, in conjunction with the safety light curtain 4, provides dual protection through both mechanical and light curtain mechanisms, ensuring operator safety. This design is simple and economical to manufacture.

[0026] It should be noted that the safety protection device 100 also includes a controller. The safety light curtain 4 and the working mechanism 200 are both electrically connected to the controller. The controller is used to shut down the working mechanism 200 when it is in operation and the safety light curtain 4 senses personnel. In this embodiment, the controller can be a PLC controller from the prior art. By electrically connecting the working mechanism 200 and the safety light curtain 4 to the controller, the working mechanism 200 can be automatically shut down, preventing the safety light curtain 4 from remaining in operation after personnel enter the work area, thus further improving the safety protection of the safety protection device 100.

[0027] In another embodiment, the flip drive 32 and the controller are also electrically connected. The controller can be used to activate the flip drive 32 when the working mechanism 200 is in the open state, so that the flip drive 32 drives the protective plate 31 to flip from the pedal position to the protective position. The controller can also be used to activate the flip drive 32 when the working mechanism 200 is in the closed state, so that the flip drive 32 drives the protective plate 31 to move from the protective position to the pedal position. Through the linkage of the controller, the working mechanism 200, the flip drive 32 and the safety light curtain 4, the ease of use and safety of the safety protection device 100 can be greatly improved.

[0028] like Figure 1 As shown, the safety light curtain 4 includes two light curtain uprights 41 arranged opposite each other along the X direction. The two light curtain uprights 41 enclose the working area, and the first and last ends of the light curtain uprights 41 are flush with the first and last ends of the ground rail 2. The light curtain uprights 41 can extend along the Y direction (i.e., the front-to-back direction). The ground rail 2 and the light curtain uprights 41 extend in the same direction. The two light curtain uprights 41 are arranged opposite each other along the X direction (i.e., the left-to-right direction). The column 210 can extend along the Z direction (i.e., the up-and-down direction). By having the two light curtain uprights 41 set on both sides of the working mechanism 200, the left and right sides of the working mechanism 200 can be fully protected. Moreover, the first and last ends of the light curtain uprights 41 are flush with the ground rail 2, which further improves the adequacy of the safety protection provided by the safety light curtain 4.

[0029] Specifically, the first and last ends of the protective plate 31 are flush with the first and last ends of the ground rail 2, and the protective plate 31 is provided with a limiting groove for the limiting working mechanism 200. Two grating uprights 41 surround the two protective plates 31, so that the protective plate 31 is located between the grating uprights 41 and the column 210. The protective plate 31 extends in the front-back direction, which is consistent with the extension direction of the grating uprights 41 and the ground rail 2. When the working mechanism 200 is in the starting position (in the non-operating state, the working mechanism 200 is generally stopped at one end of the Y direction of the working area), the limiting groove of the protective plate 31 is set corresponding to the column 210 in the starting position. When the working mechanism 200 is in the non-operating state, the flipping drive 32 drives the protective plate 31 to flip to the pedal position, so that the limiting groove on the protective plate 31 engages with the column 210, limiting the working mechanism 200 and preventing it from moving, thereby further improving the protective safety of the safety protection device 100.

[0030] In one embodiment, there are two columns 210, which are arranged opposite each other along the X direction. Each column 210 is provided with a mechanical protection mechanism 3, and the two columns 210 are located between the two mechanical protection mechanisms 3. In this embodiment, the mechanical protection mechanism 3 is set according to the number of columns 210, which can protect the periphery of each column 210 and ensure the safety of the safety protection device 100.

[0031] In this embodiment of the invention, the protective plate 31 is hinged to the tilting drive 32 via a hinge frame 33, with the hinge frame 33 positioned on the side of the tilting drive 32 away from the column 210. The hinge frame 33's placement on the tilting drive 32 away from the column 210 prevents the column 210 from interfering with the mechanical protective mechanism 3, thus ensuring the stability of the mechanical protective mechanism 3 in use.

[0032] It should be noted that the top of the sinking trough 1 is provided with a stepped portion of the limiting support protective plate 31, so that the top of the protective plate 31 located at the pedal position is flush with the top of the sinking trough 1, and the top surface of the protective plate 31 located at the pedal position is flush with the opening of the sinking trough 1, which can ensure that the protective plate 31 used as a pedal will not cause the operator to trip; in addition, the bottom of the protective plate 31 is provided with a reinforcing rib 311, which can enhance the support stability of the protective plate 31.

[0033] In one embodiment, the flipping drive 32 is used to drive the protective plate 31 to flip between 0 degrees and 90 degrees, so that the protective plate 31 in the protective position is perpendicular to the ground; and the flipping drive 32 is one of a lifting cylinder, a hydraulic cylinder, or an electric cylinder. In this embodiment, the protective plate 31 in the protective position is perpendicular to the ground, which can ensure the protrusion length of the protective plate 31 relative to the ground, and can protect personnel entering the area where the working mechanism 200 is located as much as possible. In other embodiments, the rotation angle of the protective plate 31 can be set according to actual usage requirements.

[0034] It should be noted that when the ground rail 2 is sunk to the ground and the working mechanism 200 is working, the protective plate 31 is driven by the flipping drive component 32 to make the protective plate 31 stand upright on the ground and act as a fence to prevent personnel from entering the work area. By extending and retracting the piston rod of the flipping drive 32, the protective plate 31 is flipped within a 90° range.

[0035] Start working mechanism 200. Starting position of working mechanism 200: Stopped at one end of the work area; The flipping drive component 32 lifts the protective plate 31, making the protective plate 31 stand vertically on the ground; After the working mechanism 200 finishes its work, it stops at the starting position. By extending and retracting the piston rod of the flipping drive component 32, the protective plate 31 is pulled back to cover the ground rail 2. The limiting groove of the protective plate 31 limits the movement direction of the working mechanism 200, making the working mechanism 200 unable to move.
