Description

Technical Field

[0001] The utility model is applicable to the technical field of road sweeper components and provides a quick disassembly and assembly structure of a vehicle spray rod. Background Art

[0002] A road sweeper is a common special vehicle for cleaning urban roads. A spray boom is generally provided at the bottom of the vehicle frame. When the spray boom is connected to a water pump and a water tank, high-pressure water flow can be sprayed onto the road surface to clean the road surface. After a certain period of operation, the high-pressure nozzle of the spray boom is easily clogged by debris splashed from the road. This determines that the high-pressure nozzle on the spray boom needs to be regularly unblocked and cleaned in daily use. Since the high-pressure nozzle is set close to the ground, it is difficult to directly enter the bottom of the vehicle for cleaning. Therefore, the entire spray boom is generally removed from the vehicle for cleaning. The conventional spray boom fixing method is generally fixed with a bolt pipe clamp. The bolt pipe clamp needs to completely remove the fixing bolts when disassembling, which is more troublesome, and the fixing bolts are also easy to lose. At the same time, the bolt pipe clamp is not firm enough to fix the spray boom. After long-term use, it is easy to loosen the locking bolts due to vibration, resulting in problems such as spray boom movement and rotation deviation. Utility Model Content

[0003] To this end, the utility model provides a vehicle spray bar quick disassembly and assembly structure, which realizes the firm clamping and quick disassembly of the bottom spray bar through the spray bar quick disassembly fixing mechanism. The upper clamping block and the lower clamping block cooperate to clamp in a simple structure and are quick to disassemble and assemble.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a vehicle-use spray boom quick disassembly and assembly structure, comprising:

[0005] A bottom spray bar, wherein the outer side wall of the bottom spray bar is provided with a plurality of high-pressure spray nozzles;

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0019] For example, see the attached Figure 1 The utility model provides a vehicle-use spray boom quick disassembly and assembly structure, including a bottom spray boom 1, a plurality of high-pressure nozzles 2 are arranged on the outer side wall of the bottom spray boom 1, and a quick-change joint 4 is connected to one end of the bottom spray boom 1. The quick-change joint 4 is different from the threaded tightening connection method adopted by the traditional joint. The quick-change joint 4 adopts a simple push-pull operation to realize the installation or separation between the pipes. Its specific structure is the existing technology and is not described in detail here. The bottom spray boom 1 is connected to the main water supply pipe by a quick-change joint 4, which can simplify the removal and installation operation of the bottom spray boom 1. At the same time, two spray boom quick-release fixing mechanisms 3 are provided along the axial interval of the bottom spray boom 1, as shown in the attached figure. Figure 2 As shown, the spray rod quick release fixing mechanism 3 includes an upper clamping block 31, a lower clamping block 32 and a locking assembly. The upper clamping block 31 is hinged to the lower clamping block 32. Figure 3 As shown, the lower clamping block 32 is fixedly connected to the road sweeper frame 5, the upper clamping block 31 is provided with an upper clamping groove, the lower clamping block 32 is provided with a lower clamping groove adapted to the upper clamping groove, the bottom spray rod 1 is arranged between the upper clamping groove and the lower clamping groove, the locking assembly includes a first locking rod 33, a second locking rod 36, a buckling rod 34 and a connecting rotating rod 35, the second locking rod 36 is arranged parallel to the first locking rod 33, the two ends of the buckling rod 34 are respectively fixedly connected to the first locking rod 33 and the second locking rod 36, the connecting rotating rod 35 is rotatably connected to the upper clamping block 31, and the two ends of the connecting rotating rod 35 are respectively movably sleeved on the outside of the first locking rod 33 and the outside of the second locking rod 36 On the other hand, the first locking rod 33 and the second locking rod 36 are both threadedly screwed with an upper locking nut 37, and the upper locking nut 37 is arranged above the connecting rotating rod 35. At the same time, the first locking rod 33 and the second locking rod 36 are both threadedly screwed with a lower limit nut 38, and the lower limit nut 38 is arranged below the connecting rotating rod 35. The upper locking nut 37 cooperates with the lower limit nut 38 to achieve dead point locking of the connecting rotating rod 35, which can alleviate the problem of nut loosening caused by vibration after long-term use. A fastening groove 39 for the fastening rod 34 to be buckled upward is fixedly provided on one side of the lower clamping block 32. By adjusting the upper locking nut 37, the fastening rod 34 can be buckled into the fastening groove 39 and locked.

[0020] The working principle of this embodiment is as follows:

[0021] Refer to the attached Figure 3 When installing the bottom spray boom 1, first connect the bottom spray boom 1 to the main water supply pipe through the quick-change joint 4. At this time, the fastening rod 34 and the fastening groove 39 are in a disengaged state, and the upper clamping block 31 is rotated open. Then, the bottom spray boom 1 is placed in the lower clamping groove of the lower clamping block 32. Then, the upper clamping block 31 is rotated until the upper clamping groove abuts against the bottom spray boom 1. At the same time, the fastening rod 34 is rotated to below the fastening groove 39. At this time, the upper locking nut 37 of the first locking rod 33 and the second locking rod 36 is adjusted downward to make the fastening rod 34 and the connecting rod 35 The spacing between them gradually decreases until the fastening rod 34 is buckled into the fastening groove 39 and fits tightly with the bottom of the groove. At this time, the spray rod quick-release fixing mechanism 3 completes the clamping of the bottom spray rod 1. Finally, the lower limit nuts 38 of the first locking rod 33 and the second locking rod 36 are adjusted upward so that the two lower limit nuts 38 fit tightly with the lower end of the connecting rotating rod 35. In this way, the upper locking nut 37 and the lower limit nut 38 firmly clamp the connecting rotating rod 35 between the two to form a dead point lock, ensuring that the spray rod quick-release fixing mechanism 3 can still maintain its clamping effect under vibration conditions;

[0022] When the bottom spray boom 1 needs to be disassembled, first adjust the lower limit nut 38 of the first locking rod 33 and the second locking rod 36 downward to cancel the dead point lock on the connecting rotating rod 35, and then adjust the upper locking nut 37 of the first locking rod 33 and the second locking rod 36 upward to gradually increase the distance between the fastening rod 34 and the connecting rotating rod 35 until the fastening rod 34 has enough space to rotate out of the fastening groove 39, and then rotate the upper clamping block 31 to disengage from the bottom spray boom 1. At this time, the bottom spray boom 1 is in a non-clamped state. Only the quick-change connector 4 needs to be operated to disengage the bottom spray boom 1 from the road sweeper frame 5, so as to carry out the high-pressure nozzle 2 cleaning operation. After the cleaning is completed, continue to re-install the bottom spray boom 1 on the road sweeper frame 5 according to the above scheme. The entire disassembly and assembly process is quick and convenient, and the clamping of the bottom spray boom 1 is also firm enough.
