[0033] The specific structure of a ladder device for a fire truck provided by an embodiment of the utility model and the corresponding technical effects thereof are described in detail below in conjunction with the patent drawings.
[0034] An embodiment of the utility model provides a fire truck (not shown in the figure), which includes a vehicle body, an equipment box and a ladder device 1. The ladder device 1 includes a mounting seat 100, a connecting piece 200 and a first ladder 300. The mounting seat 100 is the bottom frame of the equipment box, that is, the mounting seat 100 is integrated at the bottom of the equipment box.
[0035] It can be seen from this that since the mounting base 100 is integrated at the bottom of the equipment box, the space for installing the ladder in the equipment box itself can be saved, thereby reserving more available space for the arrangement of the on-board equipment.
[0036] For details, please refer to Figure 1-Figure 3 The mounting base 100 is provided with a housing cavity 170, and a track 160 extending along a first direction is provided in the housing cavity 170. The track 160 has an end close to an opening 171 of the housing cavity 170 and a beginning far away from the end in the first direction. The connecting member 200 is connected to the track 160, and the connecting member 200 can move relative to the track 160. The first ladder 300 is hinged to one end of the connecting member 200.
[0037] When the connecting member 200 is at the end of the track 160, the first ladder 300 can rotate relative to the connecting member 200 at a first preset angle and then stop, so that the first ladder 300 is in an open state. When the connecting member 200 is at the end of the track 160, the first ladder 300 and the connecting member 200 are accommodated in the accommodating cavity 170. In detail, at this time, the arrangement direction of the first ladder 300 and the connecting member 200 is the same as the first direction.
[0038] When the first ladder 300 is in the open state, the operator can approach the equipment box of the fire truck through the first ladder 300, so that the operator can take the equipment in the equipment box. When the first ladder 300 is in the storage state, the first ladder 300 is located in the storage cavity 170 and does not occupy the space in the equipment box, thereby improving the utilization rate of the space in the equipment box.
[0039] In the present embodiment, the ladder device 1 further comprises a second ladder 400, which is hinged to one end of the first ladder 300 away from the connecting member 200. When the first ladder 300 is in an open state, the second ladder 400 can rotate relative to the first ladder 300 at a second preset angle and then stop. At this time, the first ladder 300 and the first ladder 300 have the same extension direction. It can be understood that, through the provision of the second ladder 400, the distance of the ladder device 1 can be clamped to reduce the distance between the ladder and the ground, making it convenient for operators to enter the equipment box through the first ladder 300 and the second ladder 400 to take out the fire-fighting equipment.
[0040] When the connecting member 200 is at the starting end of the track 160, the first ladder 300, the second ladder 400 and the connecting member 200 are all accommodated in the accommodating cavity 170. It should be noted that when the arrangement direction of the first ladder 300 and the connecting member 200 is consistent with the first direction, at this time, the second ladder 400 can be rotated relative to the first ladder 300 so that the second ladder 400 is fitted with the first ladder 300. At this time, the end of the second ladder 400 away from the first ladder 300 is also in the accommodating cavity 170 and away from the opening 171 of the accommodating cavity 170.
[0041] Since the second ladder 400 can also be accommodated in the accommodating chamber 170, when the second ladder 400 is accommodated, the second ladder will not occupy the space in the equipment box, which also improves the utilization rate of the space in the equipment box.
[0042] In detail, the mounting base 100 includes a bottom plate 140, a first side plate 110 and a second side plate 120. The first side plate 110 and the second side plate 120 are spaced apart from each other along the second direction on the bottom plate 140, and the first direction and the second direction form an angle. In this embodiment, the first direction is perpendicular to the second direction. Of course, the perpendicularity in this embodiment should not be limited to the verticality in a strict sense, as long as the first direction is substantially perpendicular to the second direction.
[0043] In detail, in order to improve the strength of the mounting base 100, the mounting base 100 also includes a third side plate 130 connected to the base plate 140, the first side plate 110 and the second side plate 120 are respectively arranged on both sides of the third side plate 130, and the side of the accommodating cavity 170 away from the third side plate 130 is an opening 171 of the accommodating cavity 170.
[0044] In this embodiment, the bottom plate 140 is provided with a track 160 . It can be understood that the track 160 is provided on the bottom plate 140 , which can ensure that the track 160 has sufficient support.
[0045] Of course, in some other embodiments, the first side plate 110 and the second side plate 120 may also be provided with tracks 160 .
[0046] Optionally, in some other embodiments, the bottom plate 140 , the first side plate 110 and the second side plate 120 are all provided with rails 160 to ensure that the connecting member 200 slides stably on the rails 160 .
[0047] Optionally, at least one of the bottom plate 140, the first side plate 110, and the second side plate 120 is provided with a strip hole 150 extending along the first direction, and the outer wall of the connecting member 200 is provided with a limit pin 230 group, the limit pin 230 group includes at least one limit circle, and the limit pin 230 extends out of the strip hole 150 and can slide in the extension direction of the strip hole 150.
[0048] In this embodiment, the first side plate 110 and the second side plate 120 are both provided with a strip hole 150 extending along the first direction, and the connecting member 200 has a first side 210 and a second side 220 relative to each other. The first side 210 and the second side 220 are both provided with a set of limiting pins 230. The limiting pins 230 on the first side 210 are arranged in the strip hole 150 on the first side plate 110, and the limiting pins 230 on the second side 220 are arranged in the strip hole 150 on the second side plate 120. That is to say, through the cooperation between the limiting pins 230 and the strip holes 150, the connecting member 200 can be prevented from sliding beyond the limit on the track 160, thereby preventing the connecting member 200 from falling off the track 160.
[0049] In this embodiment, there are two rails 160, and the two rails 160 are arranged on the bottom plate 140 at intervals along the second direction. One of the two rails 160 abuts against the inner wall of the first side plate 110, and the other of the two rails 160 abuts against the inner wall of the second side plate 120 to improve the connection strength of the rails 160.
[0050] In detail, in this embodiment, the number of the limiting pins 230 in each group of limiting pins 230 is two, and the two limiting pins 230 are arranged at intervals along the first direction, that is, the first side 210 of the connecting member 200 has two limiting pins 230 arranged at intervals along the first direction, and the second side 220 of the connecting member 200 has two limiting pins 230 arranged at intervals along the first direction. It can be understood that when the end of the connecting member 200 away from the first ladder 300 is at the beginning of the track 160, the limiting pin 230 close to the beginning of the track 160 abuts against the inner wall of the bar hole 150 close to the beginning, and when the end of the connecting member 200 close to the ladder is at the end of the track 160, the limiting pin 230 close to the end of the track 160 abuts against the inner wall of the bar hole 150 close to the end, so as to limit the movement of the connecting member 200 in the first direction.
[0051] Optionally, in this embodiment, the connecting member 200 is also provided with a positioning member, and the positioning member and the mounting seat 100 have a locked state and an unlocked state. When the positioning member and the mounting seat 100 are in the locked state, the connecting member 200 and the track 160 are relatively fixed. At this time, the connecting member 200 will no longer move on the track 160. It can be understood that when the first ladder 300 and the second ladder 400 are in the open state, in order to ensure that the operating personnel can stand stably on the first ladder 300 and the second ladder 400, the positioning member and the connecting member 200 can be put into a locked state at this time to prevent the connecting member 200 from moving on the track 160.
[0052] When the positioning member and the mounting seat 100 are in an unlocked state, the positioning member can move on the track 160 .
[0053] For example, in some embodiments, the positioning member is a positioning pin, and the base plate 140 of the mounting base 100 is provided with a first pin hole and a second pin hole that cooperate with the positioning pin. When the positioning member moves away from one end of the first ladder 300 to the beginning of the track 160, the positioning pin can be inserted into the first pin hole to put the positioning member and the mounting base 100 in a locked state. When the positioning member moves close to one end of the first ladder 300 to the end of the track 160, the positioning pin can be inserted into the second pin hole to put the positioning member and the mounting base 100 in a locked state.
