Description

Technical Field

[0001] The utility model relates to the technical field of municipal sanitation equipment, in particular to a water flushing pipe coil auxiliary device. Background Art

[0002] High-pressure water flushing vehicles are a type of high-efficiency cleaning equipment widely used in the field of sanitation. They are usually composed of a water pump, a high-pressure water gun, a water pipe, a power unit (such as a gasoline engine or an electric motor), and a control system. Due to advantages such as strong mobility, high-pressure water flushing vehicles have gradually extended from the municipal sanitation field to the fields of garden maintenance, industrial cleaning, and agricultural maintenance. However, in actual work and use, we found that during the retraction and release of the water flushing pipe of the high-pressure water flushing vehicle, the operator needs to hold the water flushing pipe in his hand and manually coil the water flushing pipe. If the surface of the water flushing pipe is damaged and the internal steel wire is exposed, the operator is easily stabbed, posing a safety hazard.

[0003] In order to solve the above problems, the industry has designed a structure to assist the pipe outlet on the hose reel of the water flushing vehicle. For example, the Chinese utility model patent with the authorization announcement number CN210655701U discloses a vehicle hose reel, which includes a cleaning vehicle body and a hose reel, which is installed at the rear of the cleaning vehicle body. The hose reel includes a rotating shaft installed at the rear end of the cleaning vehicle body and a limit plate installed at both ends of the rotating shaft. The limit plate is connected to the rotating shaft through a bearing, and a pipe outlet device is installed on one side of the limit plate. At the same time, a rotating device is provided at the end of the rotating shaft away from the cleaning vehicle body. A water pipe is coiled in the hose reel, and the water pipe head of the water pipe is installed in the pipe outlet device. The position of the water pipe head is fixed by the pipe outlet device. At the same time, the rotating device provided on the hose reel facilitates the staff to collect the water pipe after it is used up. This hose reel can be used for the water flushing pipe of the high-pressure water flushing vehicle, but in actual use, we found that it requires a large range of adjustment of the hose reel, and it is not suitable for water flushing pipes of different diameters. This is not conducive to the application of this technology in existing high-pressure water jet vehicles and increases the cost of promoting the use of this technology. Summary of the invention

The present utility model can also be implemented or applied through other different specific examples, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0027] An embodiment of the present utility model provides a water flushing pipe coil auxiliary device (hereinafter referred to as this auxiliary device), and this auxiliary device has the following structural characteristics:

[0028] As Figures 1 to 4As shown in the figure, this auxiliary device includes a fixed seat 01 and a pipe belt guiding frame 02. The pipe belt guiding frame 02 includes a support frame 021 and a guide wheel assembly 03. The support frame 021 is a set of two support plates 022 arranged oppositely. A first fixed through hole 023 is provided at the top end of the support plate 022, and a guide through hole 024 is provided at the bottom end of the support plate 022. The guide wheel assembly 03 includes a first guide wheel 031 and a second guide wheel 032 arranged side by side up and down, and a first fixing plate 033 and a second fixing plate 034 arranged oppositely. The first guide wheel 031 and the second guide wheel 032 are detachably fixed between the first fixing plate 033 and the second fixing plate 034. This detachable fixing can be that the first fixing plate and the second fixing plate are provided with fixed through holes, and the rotating shafts of the first guide wheel and the second guide wheel pass through the fixed through holes and are fixed by screws, etc. The first guide wheel and the second guide wheel are provided with annular grooves 036 recessed towards the middle. The outer side walls of the first fixing plate 033 and the second fixing plate 034 are detachably connected to the first fixed through holes 023 of the support plate 022 through first studs 035. A clamping portion 011 is provided on one side of the fixed seat 01, and a columnar guide rail 012 is provided on the other side of the fixed seat 01. The columnar guide rail 012 is connected to the fixed seat 01 through a connecting plate 013. The columnar guide rail 012 is sleeved in the guide through hole 024 of the support plate 022, and the support plate 022 can slide reciprocally on the columnar guide rail 012. The connecting plate 013 plays a role in limiting the sliding of the support plate. The clamping portion 011 of the fixed seat 01 includes a top plate 014 and a side plate 015 fixedly connected perpendicular to each other. Two second studs 016 are provided at the bottom of the top plate 014. An adjustable clamping plate 017 and a fastening screw 018 are sleeved on the second studs 016.

[0029] During the installation process of this auxiliary device, the support plate is sleeved on the columnar guide rail of the fixed seat, and then the first fixing plate and the second fixing plate are respectively detachably and fixedly connected to the oppositely arranged support plates. The distance between the two support plates is adjusted, and the first guide wheel and the second guide wheel are installed. During use, first clamp the hose reel base of the high-pressure water flushing vehicle through the movable clamping plate and the top plate of the fixed seat, and adjust the fastening screw to make the interactive clamping plate and the top plate squeeze the hose reel base and form a fixed connection with it. Then remove the second guide wheel of the guide wheel assembly, place the water flushing pipe on the annular groove of the first guide wheel, install the second guide wheel, and make the second guide wheel squeeze the water flushing pipe downward. The first guide wheel supports the water flushing pipe, and together with the second guide wheel, they play the role of guiding the water flushing pipe and assisting the hose reel in taking in and releasing the water flushing pipe. The water flushing pipe coiling auxiliary device of the embodiment of the present utility model can be installed on high-pressure water flushing vehicles with different models and different pipe diameters of water flushing pipes. It can not only avoid the operator from holding the water flushing pipe by hand and manually coiling the water flushing pipe, thereby avoiding the safety hazard of the operator being pricked due to the surface damage of the water flushing pipe and the exposure of the internal steel wire. At the same time, due to the flexible installation method of the fixed seat, this auxiliary device can be installed on high-pressure water flushing vehicles with different models and different pipe diameters of water flushing pipes, effectively solving the technical problems that the existing coiler needs to make a large range of adjustments to the hose reel and cannot be applied to water flushing pipes with different pipe diameters.

[0030] Specifically, in one embodiment, the first fixing plate 033 is provided with a first conduction groove 037. The rotating shafts on one side of the first guide wheel 031 and the second guide wheel 032 pass through the first conduction groove 037 and are detachably and fixedly connected to the first fixing plate 033, specifically, it can be fixedly connected by screws 038. The second fixing plate 034 is provided with a second conduction groove 039. The rotating shaft on the other side of the first guide wheel 031 passes through the second conduction groove 039 and is detachably and fixedly connected to the second fixing plate 034. The rotating shaft on the other side of the second guide wheel is not fixedly connected to the second fixing plate, which is convenient for clamping the water flushing pipe during use. At the same time, the distance between the first guide wheel and the second guide wheel can be conveniently adjusted through the first conduction groove and the second conduction groove, so that this auxiliary device is applicable to water flushing pipes with different pipe diameters.

[0031] In another embodiment, brush bristles 040 are provided on both side walls of the first fixing plate 033 and the second fixing plate 034, and the brush bristles 040 form two sets of oppositely arranged brush groups. The brush groups can remove the sediment on the pipe wall of the water flushing pipe during the process of taking in and releasing the water flushing pipe, playing a role of preliminary cleaning.

[0032] Specifically, both side walls of the first fixing plate 033 and the second fixing plate 034 are provided with a brush fixing frame 041, and a first threaded through hole 042 is provided on the top of the brush fixing frame 041. The first threaded through hole 042 is detachably connected to a knob screw 043, and the brush 040 is sleeve-connected to the brush fixing frame 041 and is squeezed and fixedly connected by the knob screw 043. The brush is fixed by tightening the knob screw, and the brush is replaced by loosening the knob screw.

[0033] In one embodiment, a third conducting groove 025 is provided on the support plate 022, and a connecting screw 026 is detachably connected between the two support plates 022 through the third conducting groove 025. A pipe pressing assembly 05 is detachably fixedly connected to the connecting screw 026, and the pipe pressing assembly 05 includes a pipe pressing rack 051 and a third guide wheel 052. A second fixed through hole 053 is provided at the bottom of the pipe pressing rack 051, and the pipe pressing rack 051 is hingedly connected to the connecting screw 026 through the second fixed through hole 053. A first hanging ear 054 is provided in the middle of the pipe pressing rack 051, and a second hanging ear 027 is provided on the bottom side wall of the support plate 022, and a downward pressing spring 055 is overlapped and connected between the first hanging ear 054 and the second hanging ear 027. During use, the third guide wheel presses against the upper pipe wall of the water flushing pipe, and through the tension of the downward pressure spring, the third guide wheel presses down the pipe reel to the guide wheel assembly section of the water flushing pipe, so that the water flushing pipe of this section is in a tensioned state, and then the water flushing pipe at the pipe reel end can be compactly arranged in the pipe reel. At the same time, as the water flushing pipes at the pipe reel end are arranged in an orderly and compact manner, the position of the water flushing pipe moves back and forth left and right with the rotation of the pipe reel, and the support plate slides left and right adaptively on the columnar guide rail under the reverse pull of the water flushing pipe.

[0034] The pipe pressing frame 051 is fixedly connected to a rotating shaft on one side of the third guide wheel 052 via a third fixing through hole 056 . To further fix the third guide wheel, the pipe pressing frame is fixedly connected to the third guide wheel 052 via an N-shaped fixing plate 057 .

[0035] Specifically, in another embodiment, two limiting nuts 028 are threadedly connected to the connecting screw 026, and the two limiting nuts 028 are respectively arranged on both sides of the second fixing through hole 053 of the pressing tube rack 051. The position of the pressing tube rack is limited by the two limiting nuts to prevent the pressing tube rack from swinging, thereby transmitting most of the reverse force of the water flushing pipe to the support plate, helping the support plate to overcome the friction between it and the columnar guide rail, and promoting it to slide left and right on the columnar guide rail.

[0036] In one embodiment, two vertically arranged and side-by-side guiding through holes 024 are provided at the bottom end of the support plate 022, and two columnar guide rails 012 matching the guiding through holes 024 are provided on the other side of the fixed seat 01. The combination of the two groups of guiding through holes and columnar guide rails can prevent the support plate from rotating during use and has a better sliding guiding effect.

[0037] Specifically, the length direction of the support plate 022 forms an inclination angle of 30-45° with the connection line of the two guiding through holes 024. By tilting the support plate forward, the distance between the guide wheel assembly and the coiling pipe reel can be increased, providing a working space for the pipe pressing frame. At the same time, the pipe pressing frame and the support body are respectively on both sides of the columnar guide rail, so that the center of gravity of this part returns to the vicinity of the columnar guide rail, reducing the offset of the gravity of this part, thereby reducing the friction between the support plate and the columnar guide rail during the sliding process and facilitating the left-right sliding of the support plate on the columnar guide rail.

[0038] In one embodiment, the annular grooves 036 of the first guide wheel 031 and the second guide wheel 032 are provided with concave arc surfaces 045 corresponding to different pipe diameters. Through this concave arc surface, a better clamping effect can be formed on the outer walls of water flushing pipes with different pipe diameters.

[0039] It should be understood that in the present invention, terms such as "first" and "second" are used to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
