[0001] This utility model belongs to the technical field of emergency rescue vehicles, and in particular relates to an emergency rescue vehicle with a liftable obstacle-breaking shovel. Background Technology

[0002] The structural components of a rescue vehicle include a chassis, a cargo box (containing rescue equipment), a power take-off and transmission, a generator (shaft-driven or independent generator set), a winch (hydraulic or electric), a truck-mounted crane (usually a folding boom type, located at the rear of the vehicle), a lifting lighting system, and an electrical system. Depending on the purpose of the rescue fire truck, the specific configuration of the vehicle will vary, such as including a truck-mounted crane, winch, and generator.

[0003] Some rescue vehicles are equipped with obstacle-breaking shovels. During use, the height of the obstacle-breaking shovel is generally controlled by a hydraulic cylinder. During operation, the hydraulic cylinder is constantly under stress. The vibration of the obstacle-breaking shovel will cause the extension and retraction end of the hydraulic cylinder to vibrate, affecting its service life. Therefore, we have proposed a rescue vehicle with a height-adjustable obstacle-breaking shovel. The hydraulic cylinder is locked in place by a hydraulic cylinder and a locking plug. The hydraulic cylinder will not be affected when the obstacle-breaking shovel is working. Utility Model Content

[0004] The purpose of this utility model is to provide a rescue vehicle with a height-adjustable obstacle-breaking shovel, which has the advantage of using a hydraulic cylinder in conjunction with a locking plug to lock the height of the obstacle-breaking shovel, so that the hydraulic cylinder is not affected when the obstacle-breaking shovel is working, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rescue vehicle with a liftable obstacle-breaking shovel, which includes a mounting plate installed on the front side of the rescue vehicle and a connecting plate installed on the rear side of the obstacle-breaking shovel. A hydraulic cylinder is fixedly installed on the front side of the mounting plate, and a connecting block is fixedly installed on the output end of the hydraulic cylinder. The front side of the connecting block is fixedly connected to the connecting plate. Two symmetrical fixing strips are fixedly connected to the front side of the mounting plate. Three locking grooves are opened on the fixing strips. A movable U-shaped locking block is provided through the connecting plate. The two ends of the U-shaped locking block are adapted to the locking grooves.

[0006] Preferably, an L-shaped limiting seat located below the U-shaped locking block is welded to the side of the connecting plate away from the mounting plate.

[0007] Preferably, the L-shaped limiting seat has two locking holes, and the U-shaped locking block has a movable locking pin that is adapted to the locking holes.

[0008] Preferably, the obstacle-breaking shovel and the connecting plate are welded together by multiple square steel bars.

[0009] Preferably, the front side of the mounting plate is fixedly connected to two symmetrical slide rails, the surface of the slide rails is slidably connected to a sliding sleeve, and the front side of the sliding sleeve is fixedly connected to the connecting plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses the extension and retraction of a hydraulic cylinder to adjust the height of the connecting plate and the obstacle-breaking shovel. After the obstacle-breaking shovel is adjusted to a suitable height, the U-shaped locking block is inserted into the inner cavity of the corresponding locking groove to lock the height of the connecting plate and the obstacle-breaking shovel. The locking pin is then inserted into the inner cavity of the corresponding locking hole to lock the state of the U-shaped locking block. This ensures that the vibrations that occur when the obstacle-breaking shovel is working will not affect the hydraulic cylinder. Thus, the purpose of using a hydraulic cylinder in conjunction with a locking plug to lock the height of the obstacle-breaking shovel is achieved, and the operation of the obstacle-breaking shovel will not affect the hydraulic cylinder.

[0012] 2. This utility model uses the cooperation of slide rail and slide sleeve. During the lifting and lowering process of the connecting plate, the slide sleeve will slide on the surface of the slide rail, which provides guidance for the movement of the connecting plate and the obstacle-breaking shovel and ensures the stability of the up and down adjustment of the obstacle-breaking shovel.

[0020] In the following description, embodiments of the present invention’s emergency rescue vehicle with a liftable obstacle-breaking shovel will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a rescue vehicle with a liftable obstacle-breaking shovel, comprising a mounting plate 2 installed on the front of the rescue vehicle 1 and a connecting plate 4 installed on the rear of the obstacle-breaking shovel 3. The obstacle-breaking shovel 3 and the connecting plate 4 are welded together by multiple square steel bars 15. A hydraulic cylinder 5 is fixedly mounted on the front of the mounting plate 2, and a connecting block 6 is fixedly mounted on the output end of the hydraulic cylinder 5. The front of the connecting block 6 is fixedly connected to the connecting plate 4. Two symmetrical slide rails 13 are fixedly connected to the front of the mounting plate 2, and sliding sleeves 14 are slidably connected to the surfaces of the slide rails 13. The front of the sliding sleeves 14 is fixedly connected to the connecting plate 4. Through the cooperation of the slide rails 13 and the sliding sleeves 14, the connecting plate 4 can be raised and lowered. During the process, the sliding sleeve 14 will slide on the surface of the slide rail 13, providing guidance for the movement of the connecting plate 4 and the obstacle-breaking shovel 3, ensuring the stability of the obstacle-breaking shovel 3 in vertical adjustment. Two symmetrical fixing strips 7 are fixedly connected to the front side of the mounting plate 2. Three locking grooves 8 are provided on the fixing strips 7. A movable U-shaped locking block 9 is provided through the connecting plate 4. The two ends of the U-shaped locking block 9 are adapted to the locking grooves 8. An L-shaped limiting seat 10 located below the U-shaped locking block 9 is welded to the side of the connecting plate 4 away from the mounting plate 2. Two locking holes 11 are provided on the L-shaped limiting seat 10. A movable locking pin 12 is provided through the U-shaped locking block 9. The locking pin 12 is adapted to the locking holes 11.

[0022] Working principle: When using this utility model, the extension and retraction of the hydraulic cylinder 5 drives the connecting plate 4 and the obstacle-breaking shovel 3 to adjust their height. After the obstacle-breaking shovel 3 is adjusted to a suitable height, the locking pin 12 is manually pulled out of the inner cavity of the outer locking hole 11 on the L-shaped limit seat 10. Then, the U-shaped locking block 9 is inserted into the inner cavity of the corresponding locking groove 8 on the fixing strip 7. At this time, the locking pin 12 is inserted into the inner cavity of the inner locking hole 11 on the L-shaped limit seat 10, locking the U-shaped locking block 9 and preventing it from moving. This locks the height of the connecting plate 4 and the obstacle-breaking shovel 3, ensuring that the vibration of the obstacle-breaking shovel 3 during operation will not affect the hydraulic cylinder 5, thus extending the service life of the hydraulic cylinder 5. When it is necessary to adjust the height of the obstacle-breaking shovel 3, the locking pin 12 is pulled out, and the U-shaped locking block 9 is adjusted to disengage from the inner cavity of the locking groove 8, which will drive the hydraulic cylinder 5 to work and adjust.

[0023] In summary: This rescue vehicle equipped with a height-adjustable obstacle-breaking shovel uses the extension and retraction of the hydraulic cylinder 5 to adjust the height of the connecting plate 4 and the obstacle-breaking shovel 3. After the obstacle-breaking shovel 3 is adjusted to a suitable height, the U-shaped locking block 9 is inserted into the inner cavity of the corresponding locking groove 8 to lock the height of the connecting plate 4 and the obstacle-breaking shovel 3. The locking pin 12 is then inserted into the inner cavity of the corresponding locking hole 11 to lock the state of the U-shaped locking block 9. This ensures that the vibrations occurring during the operation of the obstacle-breaking shovel 3 will not affect the hydraulic cylinder 5. Thus, the purpose of using a hydraulic cylinder in conjunction with a locking insert to lock the height of the obstacle-breaking shovel is achieved, ensuring that the operation of the obstacle-breaking shovel does not affect the hydraulic cylinder.
