Description
Technical Field
The utility model relates to a hoist field, concretely relates to railing door for hoist.
Background
Crane railing door makes things convenient for the current primary structure of personnel, all install locking device on the railing door, the effect that locking device played is that the hoist is whole outage when personnel open the railing door, the hoist most uses now is articulated keeper, rotatory to the keeper frame in with the keeper, realize the locking of railing door, nevertheless this kind of keeper bumps when hoist work and just can make the keeper rotate, thereby make the railing door open, lead to the complete machine outage, influence the use of hoist.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to prior art, the utility model provides a railing door for hoist is used for solving present simple and easy railing and will open because of reasons such as collision, influences the problem that the hoist used.
The technical scheme of the utility model is realized like this: the utility model provides a railing door for hoist, including first guardrail and second guardrail, install the guardrail door between first guardrail and the second guardrail, one side of guardrail door is articulated mutually with first guardrail, be provided with door lock mechanism between the opposite side of guardrail door and the second guardrail, door lock mechanism includes the backstop board of fixed connection on the guardrail door, the backstop board extends second guardrail department outwards, fixedly connected with fixed door on the second guardrail takes, fixed door takes the U type structure, the opening internal rotation that fixed door was taken is connected with the rotation portion, the one end of rotation portion is articulated mutually with fixed door is taken, the other end of rotation portion is provided with carries out spacing stop gear to the rotation portion, stop gear is located the top that fixed door was taken, when door lock mechanism is in locking, a side of backstop board is connected with the contact of second guardrail, the another side of backstop board is connected with the rotation portion contact.
The rotating part comprises an arc-shaped plate and a vertical plate, one end of the arc-shaped plate is hinged with the fixed door, the other end of the arc-shaped plate is integrally connected with the vertical plate, and the vertical plate vertically penetrates through the opening of the fixed door.
The limiting mechanism is a limiting rod, the limiting rod penetrates through the vertical plate and is fixedly connected with the vertical plate, and the bottom of the limiting rod is in contact connection with the top surface of the fixed door.
The opening end of the fixed door is fixedly connected with the second guardrail.
The technical scheme of the utility model has following positive effect: the utility model, through the matching of the stop board and the rotating part, can lock the door lock by driving the guardrail door when closing the door; the use is more convenient, and the door does not need to be stopped and locked; the rotating part is an arc-shaped plate, so that the stop plate is contacted with and can drive the arc-shaped plate to move, and locking is realized; the tail portion of arc has vertical board, need the people to lift the arc and just can realize unblanking when opening the door, prevents that reasons such as producing collision in the hoist working process from just opening the lock, improves the security.

Detailed Description
As shown in fig. 1 to 3, a rail door for a crane comprises a first guardrail 1 and a second guardrail 2, a guardrail door 3 is installed between the first guardrail 1 and the second guardrail 2, one side of the guardrail door 3 is hinged with the first guardrail 1, a door lock mechanism is arranged between the other side of the guardrail door 3 and the second guardrail 2, the door lock mechanism comprises a stop board 4 fixedly connected with the guardrail door 3, the stop board 4 extends outwards to the second guardrail 2, a fixed door 5 is fixedly connected with the second guardrail 2, the fixed door 5 is of a U-shaped structure, a rotating part is rotatably connected in an opening of the fixed door 5, one end of the rotating part is hinged with the fixed door 5, the other end of the rotating part is provided with a limiting mechanism for limiting the rotating part, the limiting mechanism is positioned above the fixed door 5, when the door lock mechanism is locked, one side surface of the stop board 4 is in contact with the second guardrail 2, the other side surface of the stop plate 4 is in contact connection with the rotating part; specifically, when the staff opens the door and goes out from guardrail door 3, when the hand is taking the door to close the door, backstop plate 4 moves right, drives the rotation portion and upwards rotates, backstop plate 4 is blocked by second guardrail 2, the rotation portion falls down, stop gear is spacing to the rotation portion, backstop plate 4 is blocked by rotation portion and second guardrail 2 to realize locking.
The rotating part comprises an arc-shaped plate 7 and a vertical plate 9, one end of the arc-shaped plate 7 is hinged with the fixed door hinge 5, the other end of the arc-shaped plate 7 is integrally connected with the vertical plate 9, and the vertical plate 9 vertically penetrates through an opening of the fixed door hinge 5; when the door lock is locked, as shown in fig. 2, the vertical plate 9 is in contact connection with the stop plate 4, and when the door is opened, a person must rotate the arc plate 7 upwards to separate the vertical plate 9 from the stop plate 4; even if a collision occurs, the door lock is not opened.
The limiting mechanism is a limiting rod 8, the limiting rod 8 penetrates through the vertical plate 9 and is fixedly connected with the vertical plate 9, and the bottom of the limiting rod 8 is in contact connection with the top surface of the fixed door jamb 5; the limiting rod 8 limits the arc-shaped plate 7, so that the arc-shaped plate 7 keeps the state shown in the figure 2 after the door is closed.
The opening end of the fixed door frame 5 is fixedly connected with the second guardrail 2; the fixed door jamb 5 is welded to the second guard rail 2.
