Description

Port gantry crane

Technical Field

The invention relates to the technical field of hoisting equipment, in particular to a port gantry crane.

Background

The gantry crane is a variant of a bridge crane and is also called a gantry crane. The device is mainly used for loading and unloading outdoor goods yards, stockyards and bulk goods. Is an essential tool in production and processing.

The gantry crane is a gantry crane with a horizontal bridge frame arranged on two support legs to form a gantry shape. Such cranes are operated on ground rails and are mainly used for carrying and installing work in open storage yards, docks, power stations, harbors, railway freight stations and the like. The hoisting mechanism, the trolley running mechanism and the bridge structure of the gantry crane are basically the same as those of a bridge crane. Because the span is big, the crane running gear adopts the drive mode respectively mostly to prevent that the hoist from producing crooked operation and increasing the resistance, even the emergence accident. The crane trolley of the gantry crane runs on the bridge, and some crane trolleys are cantilever cranes. However, the traditional gantry crane is single in function, the illuminating lamps and the like are usually installed on the gantry crane to assist in working, but the illuminating lamps are difficult to install and replace, and therefore the installation and replacement efficiency is low.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a port gantry crane.

The invention is realized by the following technical scheme:

the invention provides a port gantry crane, which comprises a cross beam, wherein the bottom end of the cross beam is fixedly connected with a slide rail, the bottom end of the slide rail is connected with an electric hoist in a sliding manner, two sides of the bottom end of the cross beam are respectively and fixedly connected with a support rod, the bottom ends of the support rods are respectively and fixedly connected with a carrying plate, four corners of the bottom end of the carrying plate are respectively provided with universal wheels, the end part of the cross beam is provided with a first pulley, the top end of the carrying plate is provided with a second pulley corresponding to the first pulley, sliding ropes are wound on the first pulley and the second pulley, lamp holders and sliding blocks are symmetrically arranged on the sliding ropes, illuminating lamps are detachably arranged on the lamp holders, the sliding blocks are in sliding connection with the outer sides of the support rods, and.

Preferably, the outer side of the supporting rod is provided with a vertical sliding rail along the vertical direction, the sliding block is a U-shaped sliding block, and the sliding block is assembled on the vertical sliding rail in a sliding manner.

Preferably, the locking mechanism is a locking screw rod, and the locking screw rod spirally penetrates through one side of the sliding block and is spirally connected with the bottom of the vertical sliding rail.

Preferably, the bottom of the vertical slide rail is provided with an internal thread through hole for being in threaded connection with the locking screw.

Preferably, an n-shaped windshield is arranged on the outer side of the support rod.

The invention has the beneficial effects that: through the pulling slide rope, the upper and lower positions of the lamp holder and the sliding block can be exchanged, so that the lighting lamp is convenient to install and replace, the lighting lamp is beneficial to reducing the installation and replacement of workers, and the working efficiency of installing and replacing the lighting lamp is beneficial to improving.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a port gantry crane according to an embodiment of the present invention.

As shown in fig. 1, an embodiment of the invention provides a port gantry crane, which includes a beam 1, a slide rail 2 fixedly connected to a bottom end of the beam 1, and an electric hoist 3 slidably connected to a bottom end of the slide rail 2. The both sides of crossbeam 1 bottom are fixedly connected with bracing piece 4 respectively, and the equal fixedly connected with in bottom of bracing piece 4 carries thing board 5, carries the bottom four corners department of thing board 5 and is provided with universal wheel 6 respectively.

First pulley 7 is all installed to 1 tip of crossbeam, carries 5 tops of thing board and corresponds first pulley 7 and install second pulley 8, and the winding is equipped with smooth rope 9 on first pulley 7 and the second pulley 8, and the symmetry is provided with lamp stand 10 and slider 11 on smooth rope 9, and demountable installation has light 12 on the lamp stand 10,

slider

11 and 4 outside sliding connection of bracing piece are provided with locking mechanical system on the slider 11.

Vertical slide rail 13 has been seted up along vertical direction in the bracing piece 4 outside, and slider 11 is the U-shaped slider, and slider 11 sliding assembly is on vertical slide rail 13. The locking mechanism is a locking screw rod 14, and the locking screw rod 14 spirally penetrates through one side of the sliding block 11 and is spirally connected with the bottom of the vertical sliding rail 13. The bottom of the vertical slide rail 13 is provided with an internal thread through hole for screw connection with the locking screw 13.

In addition, an n-shaped windshield 15 is arranged outside the support bar 4. The 15 both sides of windshield link firmly with bracing piece 4 in the vertical slide rail 13 outside, and windshield 15 is passed through to slip rope 9, lamp stand 10 and slider 11 homoenergetic, and slider 11 is fixed the back, and lamp stand 10 is located 15 tops of windshield to windshield 15 adopts transparent material to make, can not cause the shading influence, and has fine anti-wind to the slip rope 9 and blow the performance, uses in the harbor, helps less sea breeze to the influence of slip rope 9.

In the above embodiment, by pulling the sliding rope 9, the upper and lower positions of the lamp holder 10 and the sliding block 11 can be changed, so that the lighting lamp 12 is convenient to install and replace, the reduction of the installation and replacement of the lighting lamp 12 by workers is facilitated, and the improvement of the working efficiency of the installation and replacement of the lighting lamp 12 is facilitated.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
