The technical scheme of the present utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. As shown in fig. 1-7, a spray rack system before high-pressure cleaning comprises a mounting bracket 1, a spray rod mechanism 4 capable of lifting, and a lifting mechanism 2 arranged between the mounting bracket 1 and the spray rod mechanism 4; the lifting mechanism 2 comprises a slideway 6 which is obliquely arranged or vertically arranged on the mounting bracket 1; a sliding support 8 which slides up and down along the slideway 6 is arranged on the slideway 6, and the sliding support 8 is connected with the spray rod mechanism 4; a lifting driving mechanism 9 for driving the sliding support 8 to slide up and down is arranged between the mounting support 1 and the sliding support 8. The mounting bracket 1 may be directly mounted, indirectly mounted through another mechanism, fixedly connected, or rotationally or slidably connected. Specifically, two ends of the lifting driving mechanism 9 are respectively hinged to the mounting bracket 1 and the sliding bracket 8. In particular, the connection may be via a pin. Of course, in the case where the lifting drive mechanism 9 is positioned parallel to the longitudinal direction of the slide 6, one end or a fixed connection may be adopted. However, in order to provide more cushioning space and reduce accidental damage to the lift drive mechanism 9, it is preferable to also use a two-end hinged arrangement. The mounting bracket 1 is obliquely arranged or vertically provided with a slideway mounting support seat 5; the slideway 6 is arranged on the sliding mounting support seat 5. The sliding mounting support seat 5 is integrally inclined or vertically arranged, mounting seats are arranged at two ends of the sliding mounting support seat, two ends of the sliding rail 6 are arranged in holes of the mounting seats, and the two sliding ends are fixed through assembly relation. The form of the slide 6 includes, but is not limited to, an optical axis slide, a V-groove slide, a dovetail slide, etc., and is understood to be a sliding connection form capable of realizing linear movement. The lifting drive mechanism 9 effects lifting and lowering of the sliding support 8 and the mechanism thereon by power take off.

When the lifting driving mechanism 9 is lifted, the lifting mechanism 2 drives the spray rod mechanism 4 to lift, the whole front spray frame approaches to the carrying platform such as a vehicle body, and the whole front spray frame is suspended and stretched to be shortened. The front spraying frame system adopts a slideway arrangement form, has compact structure, and compared with the four-bar old structure form, the front spraying frame height lifting is designed to be in inclined linear motion, the whole space structure arrangement is compact, long connecting bars are not needed to meet the lifting height, the front spraying frame overhanging length can be effectively shortened, the front spraying frame rigidity is improved, and the system vibration is reduced. The inclined slideway 6 is arranged to realize the retraction state of the front spraying frame, the front spraying frame is retracted towards the vehicle body, and the running vehicle is further shortened in the overhanging length of the front spraying frame; the front spraying frame and the length of the vehicle are effectively reduced, and the driving and steering trafficability of the vehicle is obviously improved. The lifting mechanism 2 is in a multi-point hinge mode relative to the four connecting rods, the structure is small in amount, the overhanging is short, the rigidity is good, the overall stability of the system is good, and the reliability is high; the whole structure is more exquisite, and the lightweight design of the whole system of the front spraying frame can be effectively realized.

In particular, the sliding bracket 8 and the sliding bracket 7 can be fixed in a bolt connection mode. The double-slideway structure is adopted to support the sliding support 8 and the front spraying frame system, the fit clearance of the whole system is small, the amount of spaciousness in the running process of the whole front spraying frame system is small, and the reliability is higher. Of course, the lifting drive mechanism 9 is also disposed at a non-intermediate position on either side of the left and right slide ways 6, as well as at other suitable positions.

An upper limit mechanism and a lower limit mechanism for preventing falling are respectively arranged on the mounting bracket 1 corresponding to the upper state and the lower state of the sliding bracket 8. The upper position is the uppermost position of the setting of the slide bracket 8. The lower position is the set lowermost position of the slide bracket 8. When the lifting drive mechanism 9, such as a cylinder, carries a large force, there may be problems such as leakage or low pressure, which causes the sliding support 8 connected thereto to slide slightly downwards, thereby affecting the accuracy of the system. The upper limit mechanism and the lower limit mechanism are arranged, so that the sliding support 8 can be prevented from falling, and the safety and the precision are ensured.

The lower limit mechanism comprises a lower limit bracket 21 arranged on the mounting bracket 1, a lower limit baffle 10 is arranged on the sliding bracket 8, and when the sliding bracket 8 is in a lower state, the lower limit baffle 10 is contacted with the lower limit bracket 21 so as to support the sliding bracket 8.

The descending limit baffle 10 and the sliding block 7 are connected to move together, so long as the descending limit baffle does not interfere and can meet the requirement. In the structure of the drawings, in one or more embodiments, the down limit baffle 10 is connected to the upper end of the sliding bracket 8 or the upper end of the sliding block 7, and is sleeved on the slideway 6. For a structure with two slides 6, two of the described down limit stops 10 may be provided. The descending limit baffle 10 is arranged to be in contact with the descending limit bracket 21 so as to support the sliding bracket 8, so that the sliding bracket 8 can be effectively prevented from sliding downwards.

The descending limit baffle 10 or the descending limit bracket 21 is provided with any or all damping rubber pads 26, and the descending limit baffle 10 and the descending limit bracket 21 are contacted or pressed by a buffer part. The cushion 26 is made of a material having a cushioning effect, such as rubber, or other materials, such as plastic having a certain elasticity. In one or more embodiments shown in the drawings, a vibration reduction rubber cushion 26 is installed on the downlink limiting support 21, so that buffering and vibration reduction are realized when the limiting baffle 10 is limited in the downlink, and vibration reduction in the running process can be realized.

The upper limit mechanism comprises a limit locking mechanism 20 which is arranged on the lifting driving mechanism 9 and used for locking the state of the lifting driving mechanism; when the sliding bracket 8 is in the upper position, the lifting driving mechanism 9 is locked. The lift drive mechanism 9 may be a linear drive mechanism such as an air cylinder.

Of course, other limiting mechanisms may be employed as long as the effect of preventing falling is achieved.

A rotating mechanism 3 for driving the spray rod mechanism 4 to swing left and right is arranged between the sliding support 8 and the spray rod mechanism 4. The existing front spraying frame rotating mechanism 3 adopts a rear-mounted mode of a rotating mechanism, the rotating mechanism needs to drive the whole front spraying frame and the lifting mechanism 2 to tilt and swing together, and the whole driving power requirement is large. In addition, as the rotating twisting point is close to the rear, the front spraying frame tilts and swings at the same angle, and extends out to the vehicle body for a long time, so that the driving safety is not facilitated; according to the arrangement form of the utility model, the rotating mechanism 3 is arranged in front and is directly connected with the spray rod mechanism 4, and the spray rod mechanism 4 is only required to be driven to tilt and swing by the driving of the rotating mechanism 3, so that the overall power requirement is smaller; the front spraying frame is tilted and swung to extend out of the vehicle body less, and the driving safety is good. Of course, the existing post-placement mode is also within the protection scope of the present utility model.

The whole spray boom mechanism 4 is driven by the 11 of the rotary driving mechanism, so that the rotation around the rotary pin shaft 17 is realized, the left-right tilting of the whole front spray boom system is further realized, and the aim of driving sewage to one side of car sound during operation is fulfilled. The rotary driving mechanism may be a conventional linear driving mechanism such as a cylinder. Because the front spray rack needs to realize tilting of the left side and the right side around the rotary twisting point. The rotary power mechanism 11 thus needs to employ a power mechanism having a bidirectional power output and three-position states, such as a bidirectional three-position cylinder, as the power driving member. Meanwhile, two rotation limiting supports can be arranged at corresponding positions on the sliding support 8 and used for limiting the left-right tilting limit positions of the rotation support 16. The rotation limit support can adopt a limit structure such as an inclined plane or a groove to realize limit.
