Embodiment Construction

[0010] Such as Figure 1-2 Specific embodiments of the invention are given. The present invention is made up of control switch 1 and special working mechanism 2. The control switch 1 adopts a contact switch with high sensitivity, which increases the accuracy of the electric control system.

[0011] Special working mechanism 2 is made up of support 3, guide sleeve assembly 4, push rod assembly 5, spring 6 and tray 7. In this special mechanism, the bracket 3 is welded on the vehicle frame, the guide sleeve assembly 4 is fixed on the bracket 3 with bolts, the push rod assembly 5 moves up and down in the guide sleeve assembly 4, and the tray 7 is connected with the cylinder rod of the outrigger cylinder. The bolts are tightened, and the pallet 7 drives the push rod assembly 5 to move with the movement of the cylinder rod of the outrigger cylinder, thereby touching the control switch.

[0012] When the outrigger cylinder is stretched out, the push rod will move down under the ac...

Abstract

The invention belongs to a side forklift traveling safety guard more reliable and economical. The side forklift traveling safety guard is provided with a control switch and a special operating mechanism. The control switch connected with a forklift master switch is installed on a forklift frame. The special operating mechanism drives to turn on and off the control switch in a contacted or separating manner. The operating mechanism is installed on a forklift support leg cylinder. The safety guard is creatively designed in terms of electrical system schemes. Front and rear cylinder serial contact switches are controlled simultaneously additionally, so that a whole forklift is unable to travel when any cylinder is not retracted, and the forklift is safer for a user. Structural creative design is made, mechanical linkage is adopted, a hydraulic system is fully omitted, the cost is lowered by about 1000 Yuan, and the forklift is more reliable and economical for the user. The creative design fully meets the service performance of the side forklift under various conditions, and the whole forklift is more reliable in safety protection.

Description

technical field [0001] The invention belongs to the technical field of lifting, transporting and transporting vehicles, and in particular relates to a new type of special forklift protection device, which is used to protect the outrigger cylinder when the side forklift is walking. Background technique [0002] At present, during the working process of the side forklift, the outrigger cylinder must first be stretched out to support the ground, which can improve the lateral stability when lifting the goods; the outrigger cylinder must be retracted when the vehicle is moving, otherwise it will be damaged outrigger cylinder. The traditional safety protection device is an interlocking oil cylinder that controls the oil circuit in parallel with the outrigger cylinder and moves synchronously with the outrigger cylinder to control whether the contact switch is disconnected or not, and plays a protective role. Due to the internal damping of the hydraulic system and the motion error ...
