Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The invention relates to a road guard rail cleaning vehicle, in particular to a small guard rail cleaning vehicle which is designed by adopting reasonable measures on the basis of a tricycle. The invention aims to solve the problems of difficulty in cleaning guardrails by manpower, low efficiency, poor maneuverability of large-scale machinery and the like.

Fig. 1-3 are schematic diagrams of a guardrail cleaning device as a whole, which comprises a tricycle 12, a cleaning system 11 and a water circulation system, and enables each system of the whole tricycle guardrail cleaning vehicle to be well matched to complete respective designated work through related operations of cleaners in a tricycle cab, thereby realizing effective cleaning of a road guardrail. As shown in fig. 4, the cleaning system 11 includes a supporting frame 10 disposed on a rear bottom plate 13 of a tricycle 12, a cleaning brush holder 11-6 capable of being lifted and lowered is disposed at one side of the supporting frame 10, a cleaning brush assembly 11-2 vertically disposed is disposed on the cleaning brush holder 11-6, a semi-open type protecting cover 11-3 for collecting cleaning water is disposed at both sides and a lower portion of the cleaning brush assembly 11-2, and the cleaning brush assembly 11-2 is supplied with clean water by a water circulation system to clean the guard rails.

As shown in fig. 4, which is a schematic structural diagram of the cleaning system, when the cleaning vehicle works, the engine is started firstly, power is transmitted to the support frame 10 through the transfer device 6, and then the support frame 10 moves towards the right side through transmission of the transmission gear 8; when the cleaning brush assembly 11-2 moves to the working position, the power output of the engine is switched, the hydraulic lifting rod 11-8 starts to lift the height of the cleaning brush 15, the hydraulic lifting rod 11-8 is put down after the working position is adjusted, and the cleaning brush 15 is put in place; and starting a water circulation system to supply clean water for the cleaning brush assembly 11-2, and washing, wetting and cleaning the guard rail.

As shown in the structural schematic diagram of the cleaning brush in fig. 5, the cleaning brush assembly 11-2 includes a cleaning brush holder 11-6 horizontally arranged, the cleaning brush holder 11-6 is parallel to the tricycle 12, 3 screws 19 are arranged on the cleaning brush holder 11-6, three screws 19 are arranged in parallel, the middle part of each screw 19 is fixed perpendicular to the cleaning brush holder 11-6, two self-rotatable cleaning brushes 15 are arranged at both ends of each screw 19, two cleaning brushes 15 are respectively arranged at both sides of the cleaning brush holder 11-6, the diameters of the cleaning brushes 15 fixed at both ends of the screws 19 are gradually reduced from front to back, and the guard rails can be sequentially cleaned. The first and second groups of working brushes (big) can be powered by the hydraulic motor 18 to perform cleaning work, and the third group of working brushes (small) can be used as driven brushes without providing a power source, so that the function of the cleaning brush is to perform later simple water removal treatment on the guard railing.

As can be seen in FIG. 5, the cleaning brush 15 is connected with the screw rod 19 through the slider 17, the slider 17 is sleeved on the screw rod 19, the limiting springs 16 are connected to two sides of the slider 17, the limiting springs 16 are sleeved outside the screw rod 19, and the end parts of the limiting springs 16 and the end parts of the screw rod 19 are fixed into a whole. The design of the cleaning brush support 11-6 is mainly to consider that cement piers or other objects with width far larger than the width of the guard rail appear suddenly on some road sections, when such obstacles are met, the working width of the cleaning brush 15 can be manually adjusted without stopping, the working brush is moved outwards through the sliding block 17 by the elasticity of the limiting spring 16, and the damage or the aggravation of abrasion caused by the rigid contact of the cleaning brush 15 and the obstacles is avoided, so that the normal service life of the cleaning brush 15 is shortened. After the washing brush 15 passes over the obstacle, the washing brush 15 is returned to the normal operation position to be operated by the elastic force of the limit spring 16. Such a structure design has an advantage that it is not necessary to design an additional device for avoiding the washing brush 15, because it is possible to design an appropriate elastic force of the limit spring 16 by considering actual operation conditions (for example, what obstacles may occur on an operation path section), and adjust the elastic force of the limit spring 16 by adjusting the limit nut 14 according to actual conditions, so as to ensure the lateral movement range of the washing brush 15, thereby preventing the washing brush 15 from making a rigid contact with the obstacles during operation.

When the cleaning brush 15 works, sewage is thrown to the protective cover 11-3 of the cleaning brush 15 through centrifugal force, and the sewage is recycled to the sewage purifier 1 through the sewage suction pipe 11-1 for purification treatment. The design utilizes the elastic force of the spring, can skillfully cross some barriers encountered in the cleaning process, and simultaneously, because the support main shaft is arranged, the shaft is used as a framework and connected with an outer bracket, the structural characteristic of the support main shaft can be used as a guide reference shaft, when the guard rail is in a gap, the guide reference shaft can be used as a positioning reference, and the guard rail can be accurately aligned between the opposite cleaning brushes 15 under the condition that the cleaning device is not adjusted by observation. Through using the support main shaft as the location benchmark, cleaner just can be after several counterpoint exercises, skilled counterpoint the guardrail with cleaning brush 15 is successful, and not only easy operation has so but also avoided installing additional guiding mechanism, still practiced thrift the cost when lightening whole car bearing.

The structure of the sliding block 17 in the invention is one of the most important parts in the whole cleaning system, the structural design determines the feasibility of the movement of the whole cleaning brush system, and the structure also has influence on the use strength of the bracket, so two schemes are specially designed to be selected in the design process. Scheme 1: as shown in fig. 13a, the slider is designed to be T-shaped, and a cylindrical spring positioning pin is designed on the slider, and needs to be designed to be an inner T-shaped hollow shape for matching with the T-shaped slider supporting sleeve, that is, the slider 17 slides in the bracket sleeve and pushes the slider 17 to drive the cleaning brush 15 to move transversely through the elasticity of the limiting spring 16; scheme 2: as shown in fig. 13b, the slider 17 is designed as a circular sleeve, and only the screw 19 in the cleaning brush system needs to be designed as a smooth cylinder, and the circular slider 17 is pushed by the elastic force of the limit spring 16 to drive the cleaning brush 15 to move transversely. Two schemes of contrast can be found, and the scheme 2 processing degree of difficulty is less, and easily satisfies the use intensity, so select for use the slider 17 and the support design mode of scheme 2.

Similarly, in order to save cost, the structure of the support frame 10 is optimally designed, and the transmission gear 8 is used for transmission as a power input mode of the support frame 10. Fig. 6 and 7 are schematic structural diagrams of the supporting frame 10, the supporting frame 10 includes a vertical supporting rod 20 and transverse supporting rods 11 to 7, a chute 22 is provided between the vertical supporting rod 20 and the chassis 13, balls 21 arranged axially and radially are provided in the chute 22, hydraulic lifting rods 11 to 8 are provided on the transverse supporting rods 11 to 7, the hydraulic lifting rods 11 to 8 are connected with the cleaning brush supports 11 to 6, and the cleaning brush supports 11 to 6 are driven to move up and down.

The kinematic pair of the supporting frame 10 is divided into a main part and an auxiliary part, the kinematic pair of the auxiliary supporting frame is fixed and is fixed with a chassis 13 of a tricycle carriage, a vertical supporting rod 20 moves to drive the cleaning device to move transversely, and a relative sliding motion mode is adopted between the main kinematic pair and the auxiliary kinematic pair, namely, a smooth cylindrical sliding rod is additionally arranged between the kinematic pairs to ensure that the main kinematic pair realizes transverse motion. For the limit control of the extending distance and the position of the support frame 10, a one-way limiting spring pin can be additionally arranged between the kinematic pairs, when the extending distance of the support frame 10 meets the size of the working requirement, the support frame is blocked by the one-way limiting pin so that the support frame cannot continue to extend outwards, and when the work is finished, the support frame 10 is recovered through the characteristic that the one-way limiting pin can pass through in the reverse direction. The transverse supporting rod 11-7 is provided with a hydraulic lifting rod 11-8, and the working principle of the hydraulic lifting rod 11-8 is as follows: when the support frame 10 moves to a designated position, a hydraulic system is started through a control button of a cab, hydraulic oil is input into an oil chamber at the bottom of the hydraulic lifting rod 11-8, the hydraulic lifting rod 11-8 is pushed to ascend, the hydraulic oil in the upper oil chamber flows back to the hydraulic oil tank when the hydraulic lifting rod 11-8 ascends, and similarly, when the hydraulic piston rod descends, the hydraulic oil is injected into the upper oil chamber, and the hydraulic oil in the lower oil chamber flows back to the oil tank.

In the invention, only two places exist, which need to be powered by a hydraulic system, namely a power input position of the cleaning brush 15 and the lifting operation of the hydraulic lifting rod 11-8. Because the cleaning operation needs to be carried out after the cleaning brush device works, the working time of the hydraulic motor 18 and the hydraulic lifting rods 11-8 at the cleaning brush 15 is staggered, namely the hydraulic motor 18 starts to work after the hydraulic rod piece works, so the two parts can adopt the same set of hydraulic device to provide power, and the power parameter only needs to meet the requirement of larger part. The working time of the hydraulic motor 18 and the working time of the hydraulic lifting rod 11-8 are staggered, so a reversing valve 29 needs to be added in a hydraulic loop, the hydraulic motor 18 and the hydraulic lifting rod 11-8 are controlled to move simultaneously through the reversing valve 29, and a backpressure valve 27 needs to be added in the lifting rod loop in order to ensure that the hydraulic lifting rod 11-8 does not drop and shake suddenly due to the action of gravity in the working process.

As shown in figure 11, the water spraying device 24 comprises a water pipeline 34 arranged inside the protective cover 11-3, the water spraying nozzles 32 are arranged on the water pipeline 34 at intervals, the water spraying nozzles 32 are eight corners of the protective cover 11-3 and point to the cleaning brush 15 in the protective cover 11-3, a square protective guard 33 for supporting the water pipeline 34 is arranged in the protective cover 11-3, 8 water spraying nozzles 32 are arranged at 8 corners of the cleaning brush cover, water output from the water tank 3 is pressurized by the water supply pump 2 and then sprayed onto the protective guard by the 8 high pressure water spraying nozzles 32, and the protective guard is wetted before cleaning, because the protective guard is generally 1000 ~ 1200mm high, the whole cleaning surface can be basically covered by arranging the 4 high pressure water spraying nozzles 32 at the two sides of the protective guard diagonally opposite angles, and clean water can be effectively sprayed onto the protective guard, and clean water outside the area of the protective guard can be effectively sprayed onto the cleaning brush 15 because the spraying angle of the high pressure water spraying nozzles 32 affects the cleaning brush 15, so that the clean water is not only prevented from being sprayed out of the cleaning area due to the excessive pressure, and the waste of the cleaning area of the cleaning brush can be greatly improved according to the actual cleaning condition, and the actual cleaning effect of the cleaning device can be greatly improved.

As shown in fig. 12, a water tank 3 supplies and stores water for the cleaning vehicle, a filtered sewage inlet 3-1 and a water inlet 3-2 are arranged at the upper part of the side wall of the water tank 3, and a water outlet 3-4 is arranged at the lower part of the side wall of the water tank 3. The size is determined according to the remaining space of the cleaning vehicle compartment and the actual load weight. Considering that the speed of a vehicle is not fast, and emergency braking phenomenon can not occur due to no special reason in the working process, the impact of water caused in the box body is small, and the water tank 3 can be designed into a rectangular shape, so that the residual space can be utilized to the maximum. In order to prevent water from freely moving in the water tank 3 and affecting the stable work of the water supply system, a porous flow stabilizing grid plate 3-3 can be designed in the water tank 3, so that a multilayer structure is formed in the water tank 3, and the impact of the movement of the water in the tank on the water supply system is reduced.
