Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a combined loading platform for a large injection molding machine. Background Art

[0002] The injection molding machine requires the operator to climb up to the platform body through a ladder to perform material adding operations. However, due to the high height of large injection molding machines, the height of the ladder to the platform body will also be very high. There is no rest platform in the middle of the existing ladder. When filling is needed, the operator needs to walk continuously from the bottom of the ladder to the top, which does not meet safety regulations.

[0003] Based on the above reasons, in some injection molding machines, the ladder is divided into the first ladder and the second ladder. Figure 1 As shown, the second ladder is fixed on the side wall of the fuselage for the operator to climb onto the fuselage, and the first ladder is fixed on the platform body. The platform body is fixed on the shooting platform of the injection molding machine and will reciprocate with the shooting platform. Therefore, the end of the first ladder away from the platform body is located on the upper end surface of the fuselage and moves with the shooting platform.

[0004] After climbing onto the fuselage, the operator needs to walk a certain distance on the fuselage before contacting the first ladder. During the walking process, there is a risk of touching the dangerous area of ​​the injection component and falling from the fuselage, which results in poor safety. Utility Model Content

[0005] The utility model aims at the disadvantage of the prior art that it is dangerous for operators to climb and load materials, and provides a combined loading platform for a large injection molding machine.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A combined loading platform for a large injection molding machine comprises a fixed platform and a mobile platform. The mobile platform comprises a platform body fixed on a shooting platform and a first ladder with one end fixed on the platform body and the other end extending downwardly. The fixed platform comprises a resting platform fixedly laid on the upper end surface of the body and a second ladder with one end fixed on the resting platform and the other end extending downwardly to the ground. Protective structures are arranged on both sides of the resting platform. The first ladder reciprocates between the protective structures on the resting platform as the shooting platform moves.

[0008] With the above scheme, the operator first climbs onto the rest platform via the second ladder. The rest platform is built on the fuselage and has protective structures on both sides. At the same time, during the movement of the shooting platform, the first ladder is always on the rest platform and moves between the protective structures, so that the operator walks and rests on the rest platform, and there is no risk of touching the dangerous area of ​​the injection component. The protective structure greatly reduces the risk of the operator falling, thereby improving the safety of the operator climbing the combined loading platform.

[0009] Preferably, the protective structure includes guardrail frames arranged on both sides of the rest platform.

[0010] By adopting the above solution, a guardrail frame is set up to prevent the operator from falling off the rest platform during walking and the risk of touching the dangerous area.

[0011] Preferably, the rest platform includes a first platform and a second platform connected end to end, the second ladder is arranged on the first platform, and the first ladder reciprocates on the second platform as the shooting platform moves.

[0012] With the above scheme, the operator may not be able to see whether the shooting platform is in a stopped state when climbing the second ladder. When climbing onto the rest platform, if the shooting platform still drives the first ladder to move, the moving first ladder may collide and injure the operator who has climbed onto the fuselage. This scheme stipulates that the first ladder can only move on the second platform, and the operator climbs onto the first platform via the second ladder, thus preventing the moving first ladder from colliding and injuring the operator who has climbed onto the rest platform.

[0013] Preferably, the first platform and the second platform are vertically connected.

[0014] By adopting the above solution, the occupied area of ​​the rest platform can be reduced.

[0015] Preferably, a safety door is hingedly provided on the guardrail frame, which cooperates with the guardrail frame and the first ladder to form a closed loop when closed, and a switching protection structure that can be connected or disconnected to each other is provided between the safety door and the guardrail frame. When the safety door is opened, the switching protection structure is disconnected, and the shooting platform stops moving; when the safety door is closed, the switching protection structure is connected, and the shooting platform starts.

[0016] With the above solution, when the operator climbs onto the rest platform, if the shooting platform still drives the first ladder to move, the moving first ladder will increase the difficulty and danger of the operator's climbing. In this solution, a safety door is hinged on the rest platform. When the safety door is opened, the switching protection structure is disconnected, and the shooting platform is controlled to stop moving, ensuring that when the operator steps onto the rest platform from the second ladder, the shooting platform and the first ladder stop moving, which is convenient for the operator to climb and increases the safety of climbing. On the contrary, the safety door is closed, the switching protection structure is connected, and the shooting platform is controlled to automatically start reciprocating movement. After the safety door is closed, it cooperates with the guardrail frame and the first ladder to form a closed loop to prevent the operator from accidentally breaking in.

[0017] Preferably, the switching protection structure includes a first magnetic switch fixed on the guardrail frame and connected to the injection molding machine signal, and a first magnetic component fixed on the safety door and moving away from or close to the first magnetic switch as the safety door is opened and closed. When the safety door is opened, the first magnetic component moves away from the first magnetic switch to disconnect the first magnetic switch; when the safety door is closed, the first magnetic component moves close to the first magnetic switch to connect the first magnetic switch.

[0018] By adopting the above scheme, the safety door is opened, the safety door and the guardrail frame are separated, and the first magnetic member installed on the safety door is away from the first magnetic switch installed on the guardrail frame, so that the first magnetic switch is disconnected and the shooting platform is controlled to stop moving; conversely, the safety door is closed, the first magnetic member is close to the first magnetic switch, so that the first magnetic switch is connected and the shooting platform is controlled to start operation.

[0019] Preferably, a safety guardrail is circumferentially arranged on the platform body, a protection door is hingedly arranged on the safety guardrail to form a closed loop with the safety guardrail when closed, a second magnetic switch connected to the injection molding machine signal is fixedly arranged on the safety guardrail, and a second magnetic member is fixedly arranged on the protection door to move away from or close to the second magnetic switch as the protection door is opened and closed. When the protection door is opened, the second magnetic member moves away from the second magnetic switch to disconnect the second magnetic switch; when the protection door is closed, the second magnetic member moves close to the second magnetic switch to connect the second magnetic switch, and the first magnetic switch and the second magnetic switch are connected in series.

[0020] With the above solution, the safety guardrail reduces the risk of the operator falling from the platform body. When the protective door is opened, the protective door and the safety guardrail are separated, and the second magnetic piece installed on the protective door is away from the second magnetic switch installed on the safety guardrail, so that the second magnetic switch is disconnected and the shooting platform is controlled to stop moving; on the contrary, when the protective door is closed, the second magnetic piece is close to the second magnetic switch, so that the second magnetic switch is connected and the shooting platform is controlled to start operation. The first magnetic switch and the second magnetic switch are connected in series, which means that when any door of the safety door and the protective door is in the open state, the shooting platform is in a stationary state, so as to avoid the risk that when the operator is on the platform body, another passing operator sees that the safety door below is not closed and closes it, causing the shooting platform to move and injure the operator on the platform body.

[0021] Preferably, a first locking structure is arranged between the safety door and the guardrail frame, the first locking structure includes a first latch lock arranged on the safety door and a first latch lock buckle arranged on the guardrail frame, and a second locking structure is arranged between the protective door and the safety guardrail, the second locking structure includes a second latch lock arranged on the protective door and a second latch lock buckle arranged on the safety guardrail.

[0022] With the above solution, when the operator leaves the platform body, the protection door is closed, and the second latch lock and the second latch lock catch cooperate to lock the door, so as to prevent the protection door from opening accidentally; when the operator leaves the rest platform, the safety door is closed, and the first latch lock and the first latch lock catch cooperate to lock the door, so as to prevent the safety door from opening accidentally. Thus, the shooting platform can be operated smoothly.

[0023] Preferably, anti-fall handrails are provided on both sides of the first ladder and the second ladder.

[0024] With the above solution, the handrail protects the operator and reduces the risk of the operator falling when climbing the first ladder and the second ladder.

[0025] Preferably, both the first ladder and the second ladder are provided with anti-slip crocodile mouth foot pedals.

[0026] With the above solution, the crocodile-mouth footrest is non-slip, reducing the risk of operators falling when climbing the first and second ladders.

[0027] The utility model has significant technical effects due to the adoption of the above technical scheme: the operator opens the safety door, switches the protection structure to disconnect, the shooting platform stops moving, the operator enters the rest platform from the safety door, takes a rest on the rest platform, walks to the first ladder and climbs, during the whole process, the operator moves on the rest platform, and under the protection of the guardrail frame, there is no risk of touching the dangerous area of ​​the injection component and falling; in addition, the first ladder is stationary, which is convenient for the operator to climb and increases the safety of climbing. After the operator climbs up the first ladder and opens the protection door, he enters the platform body to perform loading operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Example

[0039] A combined loading platform for large injection molding machines, referring to Figures 1 to 10 , including fixed platforms and mobile platforms.

[0040] The fixed platform includes a resting platform 5 fixedly laid on the upper end surface of the fuselage 1, and protective structures are arranged on both sides of the resting platform 5. The resting platform 5 is fixed to the ground through a mounting frame, and the resting platform 5 is fixed to the fuselage 1 through a supporting frame. It also includes a second ladder 6 with one end fixed on the resting platform 5 and the other end extending downward to the ground. The protective structure includes guardrail frames 7 arranged on both sides of the resting platform 5 to prevent the operator from falling off the resting platform 5 and touching the dangerous area during walking.

[0041] The mobile platform includes a platform body 3 fixed on the shooting platform 2, and also includes a first ladder 4 with one end fixed on the platform body 3 and the other end extending downward. The first ladder 4 moves back and forth on the rest platform 5 as the shooting platform 2 moves, and the guardrail frame 7 is always located on both sides of the first ladder 4 during the movement of the first ladder 4 to play a protective role.

[0042] The operator first climbs onto the rest platform 5 via the second ladder 6. Since the rest platform 5 is built on the fuselage 1 and protective structures are provided on both sides, while the shooting platform 2 moves, the first ladder 4 is always on the rest platform 5 and moves between the protective structures, so that the operator walks and rests on the rest platform 5, and there is no risk of touching the dangerous area of ​​the injection component. The protective structure greatly reduces the risk of the operator falling, thereby improving the safety of the operator climbing the combined loading platform.

[0043] When the operator climbs the second ladder 6, there is a possibility that he cannot see whether the shooting platform 2 is in a stopped state. When climbing onto the resting platform 5, if the shooting platform 2 still drives the first ladder 4 to move, the moving first ladder 4 may collide and injure the operator climbing onto the fuselage 1. Therefore, the resting platform 5 includes a first platform 501 and a second platform 502 connected end to end, and the second ladder 6 is arranged on the first platform 501. The first ladder 4 moves back and forth on the second platform 502 as the shooting platform 2 moves, thereby stipulating that the first ladder 4 can only move on the second platform 502, and the operator climbs onto the first platform 501 through the second ladder 6, so as to avoid the moving first ladder 4 from colliding and injuring the operator climbing onto the first platform 501. The first platform 501 and the second platform 502 are vertically connected to reduce the occupied area of ​​the resting platform 5.

[0044] Handrails 19 are provided on both sides of the first ladder 4 and the second ladder 6 to protect the operator and reduce the risk of falling when the operator climbs the first ladder 4 and the second ladder 6. Alligator-mouth footrests are provided on the first ladder 4 and the second ladder 6, which are anti-slip and reduce the risk of slipping when the operator climbs the first ladder 4 and the second ladder 6.

[0045] When the operator climbs onto the resting platform 5, if the shooting platform 2 still drives the first ladder 4 to move, the moving first ladder 4 will increase the difficulty and danger of the operator's climbing. Therefore, a safety door 8 is hingedly provided on the guardrail frame 7, and a switching protection structure that can be connected or disconnected with each other is provided between the safety door 8 and the guardrail frame 7. When the safety door 8 is opened, the operator is allowed to enter the first platform 501, and at this time the switching protection structure is disconnected, and the shooting platform 2 stops moving, ensuring that when the operator steps from the second ladder 6 into the first platform 501, the shooting platform 2 and the first ladder 4 have stopped moving, which is convenient for the operator to climb the first ladder 4 later and increases the safety of climbing; on the contrary, the safety door 8 is closed, the switching protection structure is connected, and the shooting platform 2 is controlled to automatically start to reciprocate, and after the safety door 8 is closed, it cooperates with the guardrail frame 7 and the first ladder 4 to form a closed loop.

[0046] The switching protection structure includes a first magnetic switch 9 fixedly mounted on the guardrail frame 7, the first magnetic switch 9 is electrically connected to the injection molding machine signal, and a first magnetic member 10 is fixedly mounted on the safety door 8, and the first magnetic member 10 can be moved away from or close to the first magnetic switch 9 as the safety door 8 is opened and closed. When the safety door 8 is opened, the safety door 8 and the guardrail frame 7 are separated, and the first magnetic member 10 installed on the safety door 8 is moved away from the first magnetic switch 9 installed on the guardrail frame 7, so that the first magnetic switch 9 is disconnected, and the shooting platform 2 is controlled to stop moving; on the contrary, the safety door 8 is closed, and the first magnetic member 10 is close to the first magnetic switch 9, so that the first magnetic switch 9 is connected, and the shooting platform 2 is controlled to start operation.

[0047] The connectivity here means that when the first magnetic member 10 is close to the first magnetic switch 9, the two reeds in the first magnetic switch 9 will be magnetized and attract each other, so that the circuit is connected. The specific working principle of the first magnetic switch 9 and the signal connection and control method with the injection molding machine and the shooting table 2 are all existing technologies, which are not shown in the figure and will not be elaborated here.

[0048] The platform body 3 is provided with a safety guardrail 11 in the circumferential direction to reduce the risk of the operator falling from the platform body 3. The safety guardrail 11 is hingedly provided with a protection door 12. The safety guardrail 11 is fixedly provided with a second magnetic switch 13. The second magnetic switch 13 is electrically connected to the injection molding machine signal. The protection door 12 is fixedly provided with a second magnetic member 14. The second magnetic member 14 can be away from or close to the second magnetic switch 13 as the protection door 12 is opened and closed. When the protection door 12 is opened, the protection door 12 and the safety guardrail 11 are separated, and the second magnetic member 14 installed on the protection door 12 is away from the second magnetic switch 13 installed on the safety guardrail 11, so that the second magnetic switch 13 is disconnected, and the shooting platform 2 is controlled to stop moving; on the contrary, the protection door 12 is closed, and the second magnetic member 14 is close to the second magnetic switch 13, so that the second magnetic switch 13 is connected, and the shooting platform 2 is controlled to start operation.

[0049] The connectivity here means that when the second magnetic member 14 is close to the second magnetic switch 13, the two reeds in the second magnetic switch 13 will be magnetized and attract each other, so that the circuit is connected. The specific working principle of the second magnetic switch 13 and the signal connection and control method with the injection molding machine and the shooting table 2 are all existing technologies, which are not shown in the figure and will not be elaborated here.

[0050] The first magnetic switch 9 and the second magnetic switch 13 are connected in series, indicating that when any one of the safety door 8 and the protective door 12 is in the open state, the shooting platform 2 is in a stationary state, so as to avoid the risk of the operator on the platform body 3 being injured by the movement of the shooting platform 2 caused by another operator passing by who sees that the safety door 8 below is not closed and closes it when the operator climbs onto the platform body 3.

[0051] The series connection between the first magnetic switch 9 and the second magnetic switch 13 and the signal electrical connection between the first magnetic switch 9 and the second magnetic switch 13 and the injection molding machine are prior arts, which are not shown in the figure and will not be described in detail here.

[0052] A first locking structure is provided between the safety door 8 and the guardrail frame 7, and the first locking structure includes a first latch lock 15 provided on the safety door 8 and a first latch lock catch 16 provided on the guardrail frame 7. A second locking structure is provided between the protection door 12 and the safety guardrail 11, and the second locking structure includes a second latch lock 17 provided on the protection door 12 and a second latch lock catch 18 provided on the safety guardrail 11.
