Abstract

The utility model discloses an electric forklift attachment control protection device which comprises a gantry and a fork arranged on the gantry. Proximity sensors are arranged at two ends of the gantry and the fork, a stroke switch is positioned on the fork, and the proximity sensors and the stroke switch are electrically connected with a controller. The electric forklift attachment control protection device is simple in structure and convenient to use, and guarantees that electric forklift attachments are prevented from colliding stopping blocks in a moving process. Thus, the service life of the electric forklift attachment control protection device is prolonged, and the stability of the attachments is improved.

Description

A kind of control protective unit of electri forklift accessory
Technical field
The utility model relates to electri forklift accessory field, specifically a kind of control protective unit of electri forklift accessory.
Background technology
Electronic three-dimensional stacker handling car works in the straight line slype, and in operation process, pallet fork will constantly carry out left and right sidesway and 180 ° of rotations.The motion of pallet fork is by controller control oil pump motor, and the motor driven gear pump rotates, and sends hydraulic oil to HM Hydraulic Motor, and the HM Hydraulic Motor driven gear is realized the accessory motion., there are following two shortcomings in accessory when motion: 1. during the sidesway of the left and right sides, when pallet fork moves to high order end or low order end and block produce physical shock, not only power consumption, noise is large, and, because physical shock causes aerial goods unstable (the most lifting altitude of electronic three-dimensional stacker handling car is higher).2. vehicle is when carrying out both sides stacking or de-stacking operation, and pallet fork need to put in the shelf, if misoperation at this moment, vehicle mobile will cause goods and shelf overturning.
The utility model content
The technical problems to be solved in the utility model provides a kind of control protective unit of electri forklift accessory, and solve in the existing electri forklift accessory motion and easily collide block, and unsettled problem.
The technical solution of the utility model is:
A kind of control protective unit of electri forklift accessory; include door frame and the pallet fork that is installed on the door frame; be provided with proximity transducer on the two ends of described door frame and the pallet fork, be provided with travel switch on the described pallet fork, described proximity transducer and travel switch all are electrically connected with controller.
Described pallet fork includes to slide and is arranged at movable stand on the door frame, is arranged at the bogie truck on the movable stand, described proximity transducer is arranged at the end that turns to of movable stand and bogie truck, and described travel switch is installed on the movable stand and is positioned at the both sides of the proximity transducer on the movable stand.
Advantage of the present utility model:
The utility model is simple in structure, easy to use, and has guaranteed that the electri forklift accessory in the process of motion, is difficult for the collision block, has increased the stability of its service life and accessory itself.
Description of drawings
Fig. 1 is the structural representation under the utility model normal condition.
Fig. 2 is that the utility model sidesway is to the structural representation of left end.
Fig. 3 is that the utility model sidesway is to the structural representation of right-hand member.
The specific embodiment
A kind of control protective unit of electri forklift accessory; include door frame 1; be installed on pallet fork and controller on the door frame 1; pallet fork includes to slide and is arranged at movable stand 2 on the door frame 1; be arranged at the bogie truck 3 on the movable stand 2; the two ends of door frame are arranged at respectively the first proximity transducer 4 and the second proximity transducer 5; movable stand 2 is provided with the 3rd proximity transducer 6 with the end that turns to of bogie truck 3; on the movable stand 2 and both sides that are positioned at the 3rd proximity transducer 6 are respectively arranged with the first travel switch 7 and the second travel switch 8, the first proximity transducers 4; the second proximity transducer 5; the 3rd proximity transducer 6; the first travel switch 7 and the second travel switch 8 all are electrically connected with controller.
Use principle of the present utility model:
The utility model door frame 1 is left or when moving right, and when the first proximity transducer 4 or the second proximity transducer 5 are sensed block, namely sends a signal to controller, and controller control start stop switch disconnects the accessory stop motion; When pallet fork slides into the left side, when the second proximity transducer 5 and the 3rd proximity transducer 6 are sensed block, namely send a signal to controller, controller control start stop switch disconnects the accessory stop motion; When pallet fork slides into the right side, when the first proximity transducer 4 and the 3rd proximity transducer 6 are sensed block, namely send a signal to controller, controller control start stop switch disconnects the accessory stop motion; The first travel switch 7 and the second travel switch 8 are controlled the process that turns to of bogie trucks 3.
