Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a gantry crane with anti-falling measures for hoisting a high-voltage cabinet comprises a main beam 1, wherein two ends of the main beam 1 are connected with a vertical lower beam 2 in a welding mode, a sliding plate 3 is fixed below the main beam 1, and two ends of the sliding plate 3 are respectively fixedly connected to the lower beam 2. The sliding plate 3 is connected with a walking hoisting device 4 in a sliding way and used for lifting goods.

Side brackets 12 are respectively welded on two sides of the lower end of the lower beam 2 close to the upper position, and the lower ends of the two side brackets 12 are connected through a lower bracket 5. The upper part of the joint of the side bracket 12 and the lower beam 2 is welded with a cross beam 10, two ends of the cross beam 10 are respectively vertically welded with a pillar 101, and the lower end of the pillar 101 is respectively welded with two ends of the lower bracket 5. The bottom of the lower bracket 5 is fixedly connected with wheels 6, so that the gantry crane can move conveniently.

As shown in fig. 2 and 3, the stay 101 is also provided with an adjustment mechanism for adjusting the height. The adjusting mechanism comprises an adjusting plate 7 integrally formed inwards on the support column 101, and the adjusting plate 7 is respectively arranged at the two side edge positions of the support column 101. The outer adjusting plate 7 is provided with a row of through holes 71 in the vertical direction, and the inner adjusting plate 7 is dug with a sliding groove 72 with the length corresponding to the row of holes 71 in the vertical position.

A box body 8 is arranged between the adjusting plates 7, and a round shaft body 81 is fixedly inserted in the box body 8. The two ends of the shaft 81 are bent backward at a right angle, and the end is fixedly connected with the fixing device 14. The fixing device 14 includes a housing 141, and a side surface of the housing 141 is integrally formed with the coupling shaft 81. The inside of the shell 141 is provided with a notch 145 communicated with the upper surface of the shell 141, the inside of the notch 145 is fixedly provided with a spring 145, the other end of the spring 145 is connected with a cylindrical bolt body 143, a bump 144 is integrally formed on the upper surface of the bolt body 143 close to the middle position, the bump 144 extends out of the notch 145, the bump 144 can be shifted in the notch 145, so that the bolt body 143 is driven to slide relative to the shell 141, and the other end of the bolt body 143 extends out of the shell 141.

As shown in fig. 3 and 4, when the spring 145 is not compressed, the length of the fixture 14 is slightly longer than the width of the strut. One end of the housing 141 is slidably connected to the sliding groove 72 of the adjusting plate 7, and the other end extends out of the hole 71. When the height needs to be adjusted, the lug 144 is pulled inwards, the lug 144 drives the bolt body 143 to move inwards, the spring 142 is compressed, when the bolt body 143 leaves the hole 71, the fixing device 14 can slide downwards along the sliding groove 72, when the bolt body 143 slides to the parallel position of the hole 71 corresponding to the required height, the lug 144 is released, and the bolt body 143 extends outwards out of the parallel hole 71, so that the position of the box body 8 is fixed. As shown in fig. 2 and 5, the mounting principle of the protection net 9 is the same as that of the tape measure of the related art. The box body 8 is hollow, and a box body notch 82 is formed in one side, far away from the cross beam 10, of the box body 8. The shaft body 81 is fixedly provided with a roll-shaped spring 13, the other end of the spring 13 is connected with a roll-shaped protective net 9, the tail end of the protective net 9 is connected with three hooks 91, the direction of each hook 91 is perpendicular to the notch 82 of the box body, the hook 91 is pulled outwards, the hook 91 can drive the protective net 9 to unreel outwards and be pulled out of the box body 8, the spring 13 is stretched along with the outwards unreeling of the protective net 9, the hook 91 is loosened, and the spring 13 can drive the protective net 9 due to the elastic force of reeling, so that the protective net 9 can return to the box body 8. As shown in fig. 6, a hanging plate 11 is arranged between two fixing plates 16 close to the inside, three rows of hanging plate hooks 111 are integrally formed on the outer side surface of the hanging plate 11, and the height of the hanging plate hooks 111 is consistent with that of the holes 71. The hook 91 is pulled outwards horizontally, the hook 91 can be hung on the hanging plate hook 111 with the corresponding height, so that the protective net 9 can be fixed under the walking lifting device 4, and if the goods conveyed by the walking lifting device 4 fall, the goods can fall on the protective net 9, and the goods cannot be damaged; when the cargoes are to be unloaded, the hook 91 is pulled forwards and then pulled upwards, the hook 91 is loosened, the protective net 9 can return to the original position, and the cargoes can be unloaded. The both sides of link plate 11 are fixedly connected with link plate axle 15 respectively, and link plate axle 15 is the right angle backward and is buckled, and link plate axle 15's end an organic whole is connected with fixing device 14, and fixing device 14 is between two fixed plates 16 that are close to, and the key body 143 can pass through the fixed plate 16 of outside one side. The hanging plate 11 can be removed by inwardly pulling the protrusions 144 at both sides of the hanging plate 11 and then downwardly moving.

The working process is as follows: when needs transported goods, pulling crotch 91 forward to link plate 11 positions, detaining crotch 91 on link plate couple 111 of corresponding height, protection network 9 can unreel and spread out and walk hoisting accessory 4 below, if the goods falls, can fall on protection network 9 earlier, has played the guard action to the goods. Promote the portal crane to the position that needs, only need take off crotch 91 from link plate couple 111, loose hand just can make protection network 9 rolling back box body 8 in, lift off the goods can.

When the goods transported are large, the fixing devices 14 on the two sides of the box body 8 can be opened, the box body moves downwards along the sliding grooves 72, and when the box body is moved to a proper position, the fixing devices 14 are installed.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
