Abstract
The utility model discloses a lifting platform protection mechanism, which comprises a lifting platform and is characterized by further comprising: the micro switch is arranged on the side surface of the lifting platform plate and is in electrical signal connection with a control mechanism of the lifting platform; and the lever is hinged on the side surface of the lifting bedplate and is used for triggering the micro switch to be opened and closed when the lever acts. The utility model uses the lever to manufacture the suspension structure, uses the micro switch to detect the state of the feedback protection mechanism, adds the protection device in the descending process of the lifting platform, stops descending when encountering obstruction, and avoids causing safety accidents or personal injury.
Description
Technical Field
The utility model relates to the technical field of lifting platforms, in particular to a lifting platform protection mechanism.
Background
Referring to fig. 1 and 2, the conventional lifting platform includes a lifting platen 1, a pair of fork bars 2, 3, and a push rod motor 4, and the push rod motor 4 drives the pair of fork bars 2, 3 to move, thereby lifting the lifting platen 1. The lifting platen 1 of the conventional lifting platform may be clamped to a person or other articles during the descending process, and has potential safety hazards.
Disclosure of Invention
The utility model aims to solve the technical problem that the traditional lifting platform has potential safety hazard, and provides a lifting platform protection mechanism, which is provided with a protection device in the descending process of the lifting platform, and stops descending when encountering obstruction, so as to avoid causing safety accidents or personal injury.
In order to achieve the above object, the present utility model provides a lifting platform protection mechanism, comprising a lifting platform, characterized in that: the micro switch is arranged on the side surface of the lifting platform plate and is in electrical signal connection with a control mechanism of the lifting platform;
and the lever is hinged on the side surface of the lifting bedplate and is used for triggering the micro switch to be opened and closed when the lever acts.
In a preferred embodiment of the utility model, a nut is mounted on the side of the lifting platen, and a bolt is screwed into the nut, the bolt being used to adjust the stroke of the lever.
In a preferred embodiment of the present utility model, the lifting platform protection mechanisms are four sets, and are respectively installed on the front side and the rear side of the two sides of the lifting platform.
By adopting the technical scheme, the utility model adopts the lever to manufacture the suspension structure, adopts the micro switch to detect the state of the feedback protection mechanism, adds the protection device in the descending process of the lifting platform, stops descending when encountering obstruction, and avoids causing safety accidents or personal injury.

Fig. 3 is a schematic view showing an initial state of descent of a lifting platform mounted with the present utility model.
Fig. 4 is a schematic diagram showing the micro switch not triggered.
Fig. 5 is a schematic diagram of a microswitch triggered.
Fig. 6 is a schematic view showing a stopped state when a worker's foot is encountered during the descent of the elevating platform equipped with the present utility model.
Fig. 7 is a schematic view showing a lowering completion state of the elevating platform mounted with the present utility model.
Detailed Description
The utility model is further described below with reference to the drawings and detailed description.
Referring to fig. 3-5, there is shown an elevating platform guard mechanism comprising: the lifting table board 1, a pair of fork bars 2 and 3 and a push rod motor 4, wherein the push rod motor 4 drives the pair of fork bars 2 and 3 to move, so that the lifting table board 1 is lifted.
The lifting platform protection mechanisms are four sets, are respectively arranged on the front side and the rear side of the two side surfaces of the lifting bedplate 1, and specifically are:
a micro-switch 5 is arranged on the side surface of the lifting platform plate 1, a lever 6 is hinged on the micro-switch 5, and the micro-switch 5 is connected with a control mechanism of the lifting platform in an electric signal manner. A nut 7 is also mounted on the side of the lifting platen 1, and a bolt 8 is screwed into the nut 7, the bolt 8 being used to adjust the travel of the lever 6.
When no obstacle is encountered, the lever 6 sags due to gravity and does not trigger the microswitch 5 (see 4). When encountering an obstacle, the lever 6 can swing upwards when encountering the obstacle, and the micro switch 5 (see 5) is triggered, so that the damage (see fig. 6-7) can be effectively avoided when a worker carelessly enters the crack by feet, and the safety production standard is more met when the safety clamp is used.
