Abstract
The utility model discloses a bolt connection mechanism of jack -up gate, including railing (1) with be located railing port (2) of railing (1), the one side of shown railing port (2) pass through a pair of hinge (3) and the one side of railing (1) is connected the vertical bolt connection mechanism that is provided with of opposite side of railing port (2), railing port (2) are connected with railing (1) through bolt connection mechanism. The utility model has the advantages of simple structure, low cost, convenient to use, adopt it to prevent because the circumstances emergence that makes its shut down is thrown off to the bolt that the shake results in with vibrating, improved the security of operation.
Description
Technical field
This utility model relates to a kind of portal gantry, the latch bindiny mechanism of a kind of portal gantry.
Background technology
At present, according to crane safety codes and standards requirement, all doors on existing crane are required to the opening and closing detection arranging a safety limit switch as door, and door limit switch electric terminal is connected when the door is closed, when door is opened, its electric terminal disconnects, and crane will the power-off because circuit disconnects.Now the mounting means of universal practical door bolt is to be horizontally disposed with latch between door and railing, although this mode is feasible, but, owing to crane belongs to mobile device, crane can occur jitter and shaking when running, and the latch on door can occur the phenomenon disengaged under jitter and shaking, door is caused to throw open, door safety limit switch signal also can disconnect, and crane quits work suddenly, causes the potential safety hazard of operation.
Utility model content
The purpose of this utility model is just to provide the latch bindiny mechanism of a kind of portal gantry preventing portal gantry from opening.
The purpose of this utility model is realized by such technical scheme, a kind of latch bindiny mechanism of portal gantry, including railing and the handrail door being positioned at railing, the side of shown handrail door is connected with the side of described railing by a pair hinge, it is characterized in that: the opposite side at described handrail door is vertically provided with latch bindiny mechanism, described handrail door is connected with railing by latch bindiny mechanism.
Wherein, described latch bindiny mechanism includes the latch siphunculus B being vertically positioned on outside handrail door, it is vertically arranged with latch siphunculus A on the railing of latch siphunculus B homonymy on handrail door described, described latch siphunculus A is higher than described latch siphunculus B, and the lower surface of latch siphunculus A is slightly above the upper surface of latch siphunculus B, described latch siphunculus A is provided with bolt rod.
Owing to have employed technique scheme, this utility model has simple in construction, advantage with low cost, easy to use, and the latch using it to be prevented from causing due to shake and vibration disengages the situation making it shut down and occurs, and improves the safety of operation.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A portion zoomed-in view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail; but this utility model is not limited to these embodiments; any improvement on the present embodiment essence spirit or replacement, still fall within this utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, a kind of latch bindiny mechanism of portal gantry, including railing 1 and the handrail door 2 being positioned at railing 1, the side of shown handrail door 2 is connected with the side of described railing 1 by a pair hinge 3, opposite side at described handrail door 2 is vertically provided with latch bindiny mechanism, and described handrail door 2 is connected with railing 1 by latch bindiny mechanism.
Wherein, described latch bindiny mechanism includes the latch siphunculus B6 being vertically positioned on outside handrail door 2, it is vertically arranged with latch siphunculus A4 on the railing 1 of latch siphunculus B6 homonymy on handrail door 2 described, described latch siphunculus A4 is higher than described latch siphunculus B6, and the lower surface of latch siphunculus A4 is slightly above the upper surface of latch siphunculus B6, described latch siphunculus A4 is provided with bolt rod 5.
In this utility model, owing to bolt rod 5 is to be vertically arranged in latch siphunculus A4, in latch siphunculus B6 is inserted in lower end simultaneously, cannot come off when being rocked very much by shake, crane will not occur the phenomenon of power-off, and the safety of operation is guaranteed.
