Description

Technical Field

[0001] The utility model relates to the technical field of fire trucks, in particular to a telescopic pipe fixing device of a ladder fire truck and the ladder fire truck. Background Art

[0002] A ladder fire truck is a type of fire truck that is equipped with a telescopic ladder, a lifting bucket turntable and a fire extinguishing device for firefighters to climb up to extinguish fires and rescue trapped people. It is suitable for fighting fires in high-rise buildings.

[0003] Application number 201822163380.7 discloses a telescopic tube fixing device for a ladder fire truck and a ladder fire truck. The device includes a ladder and a mounting bracket, through which each stage of the telescopic tube is connected to the ladder, allowing the tube to extend as the ladder is raised. The mounting bracket is configured to mount the tube at an adjustable position relative to the ladder to reduce deformation of the tube during ladder elevation. This invention alleviates the problem of excessive interference caused by the extension of the tube when the ladder is extended.

[0004] This technical solution uses a telescopic structure to enable the telescopic tube to adaptively adjust its position, but the telescopic structure is difficult to adjust when lateral disturbance occurs when the ladder rotates. In addition, since the telescopic tube is a movable part, it needs maintenance and replacement of worn structures at regular intervals to avoid water leakage. This technical solution limits the fixing device by using two bolts and four nuts, resulting in the need to disassemble and install more nuts when disassembling the telescopic tube later, which is time-consuming and labor-intensive. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a telescopic tube fixing device for a ladder fire truck and a ladder fire truck to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a telescopic tube fixing device for a ladder fire truck and a ladder fire truck, comprising a fire truck body and a ladder body, a fixing seat fixed at the bottom of the ladder body, and a card slot provided at the lower side of the fixing seat, the bottom of the card slot is connected to a support seat through a card block, a baffle is connected to the inside of the fixing seat, an airbag is connected to the middle of the bottom of the fixing seat and the middle of the top of the support seat, and a reinforcing rope is provided on the inner wall of the airbag.

[0007] By adopting the above technical solution, when the telescopic tube body is deformed, the airbag will also deform to provide buffering. After the pressure disappears, the airbag restores its original shape through its own elasticity and the influence of internal air pressure, thereby supporting the telescopic tube body and resetting the support of the telescopic tube. At the same time, the strength of the airbag is increased by setting a reinforcing rope, thereby extending the service life of the airbag. The telescopic tube body is wrapped by two airbags, so that the telescopic tube body can adapt to and buffer both vertical and horizontal deformations. When the telescopic tube body needs to be disassembled for maintenance, the baffle is slid upward to end the limitation of the block, and then the support seat can be slid laterally to move the block out of the slot, thereby removing the support seat to end the limitation of the telescopic tube body. During installation, it is only necessary to push the support seat laterally to allow the block to enter the slot, and then slide the baffle downward to limit the block, thereby completing the installation operation.

[0008] Furthermore, the airbag is semicircular in shape, and the two airbags are arranged in a mirror image.

[0009] By adopting the above technical solution, the telescopic tube body is wrapped by two airbags, so the telescopic tube body can be adaptively buffered regardless of deformation in the vertical direction or the horizontal direction.

[0010] Furthermore, the reinforcement rope is a steel wire rope.

[0011] By adopting the above technical solution, when the telescopic tube body is deformed, the airbag will also be deformed to provide a buffer. At the same time, the reinforcement rope is provided to increase the strength of the airbag and extend the service life of the airbag.

[0012] Furthermore, the clamping block is slidably connected to the clamping slot, and the supporting seat is detachably connected to the fixing seat.

[0013] By adopting the above technical solution, when the telescopic tube body needs to be disassembled for maintenance, the baffle is slid upward to end the limiting of the block, and then the support seat can be slid laterally to move the block out of the slot, thereby removing the support seat to end the limiting of the telescopic tube body.

[0014] Furthermore, the baffle is slidably connected to the fixing seat, and the clamping block is slidably connected to the baffle.

[0015] By adopting the above technical solution, during installation, it is only necessary to push the support seat sideways to make the card block enter the card slot, and then slide the baffle downward to limit the card block, thereby completing the installation operation.

[0016] Furthermore, the ladder body is installed on the top of the fire truck body, and a telescopic tube body is connected to one side of the ladder body, and the telescopic tube body is connected to the airbag.

[0017] By adopting the above technical solution, when firefighting and rescue are needed, the staff can drive to the place where rescue is needed in front of the fire truck body. When high-altitude rescue operations are needed, the ladder body can be opened to raise and extend the ladder body to facilitate the staff to climb for high-altitude rescue. At the same time, the end of the ladder body is connected to the end of the telescopic tube body, and the friction between the airbag and the telescopic tube body causes the ladder body to extend while driving the telescopic tube body to extend, so that fire extinguishing operations can be carried out at high altitude through water cannon.

[0018] Furthermore, a limiting block passes through the upper part of one side of the fixing seat, and a spring is connected to one side of the limiting block, and a linkage bar is fixed to one side of the baffle.

[0019] By adopting the above technical solution, the staff presses the limit block, and then slides the linkage bar upward. After the linkage bar moves upward, it drives the two baffles to move upward, thereby ending the limitation of the card block. Then, the limit block is extended by the spring. At this time, the limit block is located at the bottom of the linkage bar, thereby supporting the linkage bar and preventing the linkage bar and the baffle from sliding down due to gravity.

[0020] Furthermore, the linkage bar is slidably connected to the fixing seat.

[0021] By adopting the above technical solution, the staff slides the linkage bar upwards, and after the linkage bar moves upwards, it drives the two baffles to move upwards, thereby completing the limitation of the card block.

[0022] Furthermore, the linkage bar abuts against the limit block, and the limit block is slidably connected to the fixing seat.

[0023] By adopting the above technical solution, the limit block is extended by the spring. At this time, the limit block is located at the bottom of the linkage bar to support the linkage bar and prevent the linkage bar and the baffle from sliding down due to gravity.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. The utility model provides an airbag and a reinforcing rope. When the telescopic tube body deforms, the airbag also deforms to provide cushioning. After the pressure disappears, the airbag returns to its original shape through its own elasticity and the influence of internal air pressure, thereby supporting the telescopic tube body and restoring the support. At the same time, the reinforcing rope increases the strength of the airbag, extending its service life. The two airbags wrap the telescopic tube body, so the telescopic tube body can adapt to and cushion deformation in both vertical and horizontal directions. It can also cushion large disturbances in both vertical and horizontal directions. The utility model has a simple structure, strong functionality, and a long service life.

[0026] 2. The utility model is provided with a card slot, a card block and a baffle. When the telescopic tube body needs to be disassembled for maintenance, the baffle is slid upward to end the limit of the card block, and then the support base can be slid laterally to move the card block out of the card slot, thereby removing the support base to end the limit of the telescopic tube body; when installing, it is only necessary to push the support base laterally to make the card block enter the card slot, and then slide the baffle downward to limit the card block, thereby completing the installation operation; the structure is simple and the disassembly and assembly are fast and convenient.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] Example 1:

A fixing seat 4 is fixed to the bottom of the ladder body 2. A slot 8 is opened at the bottom of one side of the fixing seat 4. The bottom of the slot 8 is connected to a support seat 5 through a block 9. The block 9 is slidably connected to the slot 8. The support seat 5 is detachably connected to the fixing seat 4. A baffle 10 is connected inside the fixing seat 4. The baffle 10 is slidably connected to the fixing seat 4. The block 9 is slidably connected to the baffle 10. When the telescopic tube body 3 needs to be disassembled for maintenance, the baffle 10 is slid upward to end the restriction of the block 9, and then the support seat 5 can be slid laterally to move the block 9 out of the slot 8, thereby disassembling the support seat 5 to end the restriction of the telescopic tube body 3; when installing, it is only necessary to push the support seat 5 laterally to make the block 9 enter the slot 8, and then slide the baffle 10 downward to limit the block 9, thereby completing the installation operation;

[0037] An airbag 6 is connected to the middle of the bottom of the fixing seat 4 and the middle of the top of the supporting seat 5. The airbag 6 is semicircular, and the two airbags 6 are arranged in a mirror image. The inner wall of the airbag 6 is provided with a reinforcing rope 7, and the reinforcing rope 7 is a steel wire rope. When the telescopic tube body 3 is deformed, the airbag 6 will also deform to provide buffering. After the pressure disappears, the airbag 6 restores its original shape through its own elasticity and the influence of internal air pressure, thereby supporting the telescopic tube body 3 and resetting and supporting the telescopic tube body 3. At the same time, the strength of the airbag 6 is increased by the setting of the reinforcing rope 7, and the service life of the airbag 6 is extended. The telescopic tube body 3 is wrapped by two airbags 6, so the telescopic tube body 3 can be adaptively buffered regardless of vertical or horizontal deformation.

[0038] See Figure 1 In the above embodiment, the ladder body 2 is installed on the top of the fire truck body 1, and the telescopic tube body 3 is connected to one side of the ladder body 2, and the telescopic tube body 3 is connected to the airbag 6. When firefighting and rescue are needed, the staff can drive to the place where rescue is needed in front of the fire truck body 1. When high-altitude rescue operations are needed, the ladder body 2 can be opened to make the ladder body 2 rise and extend, so that the staff can climb for high-altitude rescue. At the same time, the end of the ladder body 2 is connected to the end of the telescopic tube body 3, and the friction between the airbag 6 and the telescopic tube body 3 causes the ladder body 2 to extend while driving the telescopic tube body 3 to extend, so that fire extinguishing operations can be carried out through water cannons at high altitudes.

[0039] Example 2:

[0040] On the basis of the above embodiment 1, in order to further facilitate disassembly and assembly, the following settings are now adopted.

[0041] See Figure 2-Figure 5In the above embodiment, a limiting block 12 passes through the upper side of the fixed seat 4, the linkage bar 11 abuts against the limiting block 12, the limiting block 12 is slidably connected to the fixed seat 4, and a spring 13 is connected to one side of the limiting block 12, which drives the limiting block 12 to extend through the spring 13. At this time, the limiting block 12 is located at the bottom of the linkage bar 11, thereby supporting the linkage bar 11 and preventing the linkage bar 11 and the baffle 10 from sliding down due to gravity; a linkage bar 11 is fixed to one side of the baffle 10, and the linkage bar 11 is slidably connected to the fixed seat 4. The staff slides the linkage bar 11 upward, and after the linkage bar 11 moves up, it drives the two baffles 10 to move up, thereby ending the limitation of the card block 9.

[0042] When the locking plate 9 is in the locked position, the locking plate 9 is locked, and the locking plate 9 is locked. When the locking plate 9 is locked, the locking plate 9 is locked, and the locking plate 9 is locked. When the locking plate 9 is locked, the locking plate 9 is locked, and the locking plate 9 is locked. When the locking plate 9 is locked, the locking plate 9 is locked, and the locking plate 9 is locked. When the locking plate 9 is locked, the locking plate 9 is locked, and the locking plate 9 is locked.

[0043] When firefighting and rescue are needed, the staff can drive the fire truck body 1 to the place where rescue is needed. When high-altitude rescue operations are needed, the ladder body 2 can be opened to raise and extend the ladder body 2 so that the staff can climb up and perform high-altitude rescue. At the same time, the end of the ladder body 2 is connected to the end of the telescopic tube body 3, and the friction between the airbag 6 and the telescopic tube body 3 causes the ladder body 2 to extend and the telescopic tube body 3 to extend, so that fire extinguishing operations can be performed at high altitude by water cannon.

[0044] When the telescopic tube body 3 is deformed, the airbag 6 will also deform to provide cushioning. After the pressure disappears, the airbag 6 returns to its original shape due to its own elasticity and the influence of the internal air pressure, thereby supporting the telescopic tube body 3 and restoring the support. At the same time, the provision of the reinforcing rope 7 increases the strength of the airbag 6 and extends the service life of the airbag 6. The two airbags 6 wrap the telescopic tube body 3, so that the telescopic tube body 3 can adapt to and cushion both vertical and horizontal deformations.
