Description

Technical Field

[0001] This utility model relates to the field of vacuum truck reel technology, and in particular to a reel adjustment device for cleaning vacuum trucks. Background Technology

[0002] The cleaning and vacuum truck is a special-purpose vehicle that integrates high-pressure cleaning and vacuum suction functions. It has the functions of high-pressure cleaning, vacuum suction, and combined cleaning and suction operations. It is mainly used for cleaning, dredging, and sewage treatment of municipal sanitation facilities such as urban sewers, rainwater wells, and septic tanks.

[0003] The hose reel of a vacuum truck is a key component of a high-pressure cleaning system, primarily used for storing and releasing the high-pressure hose for easy operation and storage. After the vacuum truck has finished its work, the high-pressure hose must be neatly wound onto the reel to avoid tangling, allowing for easy pull-out next time and improving work efficiency. Common vacuum trucks are equipped with open-type hose reels. While these reels are simple in structure and low in cost, they do not provide sufficient protection for the hose. They cannot prevent the hose from being scratched or punctured by flying stones, branches, metal or glass shards during travel or operation. Furthermore, rubber or polyurethane hoses exposed to sunlight for extended periods will harden and crack due to ultraviolet radiation, thus compromising the hose's lifespan.

[0004] A search revealed that Chinese utility model patent CN206844298U discloses a combined vacuum truck with a reversible suction hose reel. The truck includes a frame body with a suction tank mounted on it. A reversible suction hose reel device is located at the rear of the suction tank. This device includes a fixed bracket connected to the rear of the suction tank, and a reversible bracket for mounting the suction hose reel. The reversible bracket and the fixed bracket are connected via a central pivot and a reversible hydraulic cylinder. A drive wheel is located on the hose reel near the reversible bracket, and the drive wheel is connected to a hydraulic motor via a transmission device. While this application uses a reversible reel to store the hose, the reel's open design makes it difficult to provide adequate protection for the hose wound on it, thus hindering the hose's lifespan. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a reel adjustment device for a cleaning and vacuuming vehicle, and the main technical problem to be solved is how to provide protection for the water pipe wound on the reel.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: A reel adjustment device for a vacuum cleaning truck includes a storage compartment and a cover plate installed on the vacuum truck. The cover plate stores the water pipe by engaging with the storage compartment. The cover plate is provided with a winding cylinder for winding the water pipe. The winding cylinder is provided with a limiting mechanism to prevent the water pipe from falling off. The limiting mechanism includes a drive assembly and several baffles. The drive assembly provides lateral protection for the water pipe by driving the baffles to deflect.

[0007] Furthermore, it also includes a support mechanism for supporting the storage compartment and the cover plate, the support mechanism including a sleeve fixedly connected to the vacuum truck and a support rod rotatably connected to the vacuum truck.

[0008] Furthermore, connecting rods are fixedly connected between the storage compartment and the sleeve, as well as between the cover plate and the support rod, with the sleeve fitted over the outside of the support rod.

[0009] Furthermore, through grooves are provided on the rod body and both sides of the sleeve. The same screw is provided on the rod and the sleeve at the through groove, and a nut is threaded to the outside of one end of the screw.

[0010] Furthermore, the winding cylinder is fixedly connected to the middle of the inner side of the cover plate, and a rotating shaft is provided through the middle of one side of the winding cylinder. Several connecting shafts are provided equidistantly through the side wall of the winding cylinder outside the rotating shaft.

[0011] Furthermore, the drive assembly includes a drive wheel connected to a rotating shaft by a key and a driven wheel connected to a connecting shaft by a key, the drive wheel meshing with the driven wheel.

[0012] Furthermore, the number of baffles is the same as the number of connecting shafts and they correspond one-to-one. The baffles are fixedly connected to the end of the connecting shaft that is outside the winding cylinder.

[0013] Furthermore, a knob is fixedly connected to one end of the rotating shaft outside the winding cylinder, and a threaded through hole is provided on one side of the knob, with a bolt threadedly connected to the knob at the threaded through hole.

[0014] Furthermore, several water holes for drainage are provided at the bottom of the storage compartment.

[0015] The beneficial effects of this utility model are as follows: 1. This application allows the water pipe wound on the drum to be stored in the storage compartment by adjusting the cover plate to engage with it. This provides a closed storage for the water pipe, preventing damage from external hard objects and reducing the aging effects of ultraviolet rays. After the water pipe is wound on the drum, adjusting the baffle to the radial direction of the drum limits the water pipe and prevents it from detaching from the drum due to vehicle vibration or road bumps during the operation of the suction truck. Therefore, this device provides protection for the water pipe. 2. By setting a threaded rod that passes through the support rod and the sleeve, the latter can adjust whether the cover plate and the storage compartment are fastened by limiting the relative rotation between the two. After the bolt is installed on the threaded rod, the state of the cover plate can be fixed to ensure the stability of the water pipe when it is open or closed and when it is fastened. 3. By opening several water holes at the bottom of the storage compartment, water can be drained from the storage compartment in time when the water pipe is still dripping after use, so as to avoid water accumulation inside and causing rust.

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0019] Example 1 See attached document Figure 1-2 This application provides a reel adjustment device for a cleaning vacuum truck, including a storage compartment 1 and a cover plate 4 installed on the vacuum truck. The cover plate 4 forms a closed space by fastening with the storage compartment 1 to store the water pipe. Within this closed space, the water pipe will not be damaged or punctured by collisions with external hard objects, and the impact of ultraviolet rays on its service life can also be reduced, thus better protecting the water pipe. The cover plate 4 is provided with a winding cylinder 5 for winding the water pipe. The winding cylinder 5 is provided with a limiting mechanism to prevent the water pipe from falling off. The limiting mechanism includes a drive component and several baffles 6. The drive component provides side protection for the water pipe by driving the baffles 6 to deflect.

[0020] Preferably, the winding cylinder 5 is fixedly connected to the middle of the inner side of the cover plate 4, and a rotating shaft 8 is provided through the middle of one side of the winding cylinder 5. Several connecting shafts 7 are provided equidistantly through the side wall of the winding cylinder 5 outside the rotating shaft 8. The drive assembly includes a driving wheel 801 connected to the rotating shaft 8 by a key and a driven wheel 701 connected to the connecting shaft 7 by a key. The driving wheel 801 and the driven wheel 701 mesh, and one driving wheel 801 and several driven wheels 701 can form a planetary gear system, thereby realizing that the driving wheel 801 synchronously drives several driven wheels 701, thereby adjusting the synchronous deflection of all the baffles 6.

[0021] Preferably, the number of baffles 6 is the same as the number of connecting shafts 7 and they correspond one-to-one. The baffles 6 are fixedly connected to the end of the connecting shaft 7 outside the winding cylinder 5. When the baffles 6 are deflected to the radial direction of the winding cylinder 5, they can provide lateral protection for the water pipe wound on the winding cylinder 5, thereby preventing the water pipe from falling off the winding cylinder 5. When the baffles 6 are deflected to the circumference of the winding cylinder 5, they can be stored to ensure the convenience of removing the water pipe from the winding cylinder 5 for use. A knob 9 is fixedly connected to the end of the rotating shaft 8 outside the winding cylinder 5. A threaded through hole is opened on one side of the knob 9, and a bolt 802 is threadedly connected to the knob 9 in the threaded through hole. The knob 9 can be fixed by the bolt 802. Therefore, after adjusting the deflection of the baffles 6 by the knob 9, fixing the knob 9 by the bolt 802 can also make the baffles 6 stable, so as to ensure that it can provide a stable limiting effect for the wound water pipe.

[0022] When using this device to load water pipes, they can be wound around the outside of the winding cylinder 5. After loosening the bolt 802, the knob 9 is turned. The knob 9 drives the drive wheel 801 to rotate via the rotating shaft 8. The drive wheel 801 drives the connecting shaft 7 to rotate via the driven wheel 701. The rotation of the connecting shaft 7 can drive the baffle 6 to deflect, thereby adjusting the baffle 6 to be in the radial direction of the winding cylinder 5. After adjusting the four baffles 6 to be arranged in a "+" shape, the baffles 6 can limit the water pipe wound on the winding cylinder 5 to prevent the water pipe from falling off the winding cylinder 5.

[0023] Preferably, the system also includes a support mechanism for supporting the storage compartment 1 and the cover plate 4. The support mechanism includes a sleeve 11 fixedly connected to the vacuum truck and a support rod 3 rotatably connected to the vacuum truck. Connecting rods 2 are fixedly connected between the storage compartment 1 and the sleeve 11, and between the cover plate 4 and the support rod 3. The sleeve 11 is sleeved on the outside of the support rod 3, and the sleeve 11 and the support rod 3 are rotatably connected by bearings to ensure the smooth rotation adjustment of the support rod 3 and the cover plate 4.

[0024] Since the screw 10 is in the state of penetrating the support rod 3 and the sleeve 11, the latter two cannot rotate relative to each other. Therefore, the cover plate 4 can be kept in the open state so that the water pipe can be taken out and put in on the winding cylinder 5. In addition, the weight of the cover plate 4 and the water pipe is borne by the support rod 3, while the weight of the storage compartment 1 is borne by the sleeve 11. Therefore, the weight brought by the water pipe will not affect the rotation adjustment of the cover plate 4.

[0025] Preferably, through grooves are provided on the body of the support rod 3 and on both sides of the sleeve 11. The support rod 3 and the sleeve 11 are provided with the same screw 10 at the through groove. A nut 12 is threaded to the outside of one end of the screw 10. By installing the screw 10 and the nut 12, the cover plate 4 can be limited to either the state of being fastened to the storage compartment 1 or the fully open state parallel to the storage compartment 1. The former can store the water pipe, while the latter can facilitate the retrieval of the water pipe.

[0026] After the water pipe is installed, the nut 12 can be turned to remove it from the screw 10. Then, the screw 10 can be pulled to detach it from the support rod 3 and the sleeve 11. At this time, the cover plate 4 can be rotated until it rotates 180 degrees. The cover plate 4 will then be locked onto the storage compartment 1, and the through grooves in the support rod 3 and the sleeve 11 can be aligned again. Therefore, the screw 10 can be passed through the through groove again, and the nut 12 can be threaded onto its end to restrict the relative rotation of the support rod 3 and the sleeve 11. Thus, the cover plate 4 can be kept locked onto the storage compartment 1 to ensure that the water pipe can be stably stored in the storage compartment 1.

[0027] Example 2 See attached document Figure 3 This application provides a reel adjustment device for a cleaning vacuum truck. Compared with embodiment 1, in order to avoid water accumulation in the storage compartment 1, a number of water holes 13 for drainage are provided at the bottom of the storage compartment 1.

[0028] After the water pipe is wound around the winding cylinder 5 and put into the storage compartment 1, if there is still dripping water on the water pipe, the water droplets can be quickly drained through the water hole 13 to avoid water accumulation in the storage compartment 1 and causing it to rust.

[0029] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
