Description

Technical Field

[0001] The utility model relates to the technical fields of agricultural and forestry land reclamation and fire fighting, in particular to a multi-position adjustable anti-collision frame. Background Art

[0002] Engineering machinery vehicles are generally equipped with anti-collision frames due to the requirements of the working environment. The anti-collision frames on engineering vehicles in the existing technology are divided into adjustable anti-collision frames and non-adjustable anti-collision frames. The non-adjustable anti-collision frames mainly play a role in protecting the vehicle's own body. The adjustable anti-collision frames can protect the vehicle body while adjusting the different angles of the anti-collision frames to adapt to different working environments such as uphill and downhill, as well as to complete the work requirements of pushing down debris and shrubs at a certain height. Common adjustable anti-collision frames are mainly divided into two types: electronically controlled hydraulic cylinder control and manually adjusted bolt control. The former is more complex in design and has high manufacturing and maintenance costs, while the latter is more cumbersome to adjust, and the adjustment process requires multiple people to cooperate in calibration, installation and positioning. Therefore, it is of great significance to develop a multi-gear adjustable anti-collision frame with simple structure and easy operation. Utility Model Content

[0003] The utility model provides a multi-position adjustable anti-collision frame to solve the problems raised in the above-mentioned background technology. To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-position adjustable anti-collision frame, comprising a mounting plate, an anti-collision frame, a support rod, a locking plate, a locking plate sliding pin and a frame. The mounting plate is located at the upper part of the frame, and is designed with a front mounting hole, a rear mounting hole, an adjustment slide groove and a sliding pin hole. The front mounting hole is hinged to the anti-collision frame through a pin shaft, and the rear mounting hole is hinged to the circular hole on the locking plate through a pin shaft, and the locking plate can rotate around the rear mounting hole. The adjustment slide groove is provided with three connected semicircular hole positions, and the distance L between the hole positions is 110mm to 130mm, preferably 120mm, and is connected to the lower end of the support rod through a pin shaft, and the position of the pin shaft can be adjusted to any one of the three semicircular hole positions, thereby realizing the adjustment of the front and rear position posture of the anti-collision frame. The sliding pin hole can be connected to the locking plate through a locking plate sliding pin. The anti-collision frame is a truss structure, which is used to protect the vehicle body and intercept obstacles close to the vehicle body. Pin-shaft mounting seats are symmetrically distributed on the bottom and upper parts of both sides of the truss. The bottom pin-shaft mounting seat of the anti-collision frame is hinged to the front mounting hole of the frame mounting plate through a pin, and the upper pin-shaft mounting seat of the anti-collision frame is hinged to the support rod through a pin. The support rod is 780mm long and has mounting holes at both ends. The upper end is connected to the upper pin-shaft mounting seat through a pin, and the lower end is connected to the adjustment groove of the mounting plate through a pin. The locking plate is a two-layer plywood with a U-shaped cross-section, connected at the top and open at the bottom. The bottom opening of the plywood is buckled on the upper end of the mounting plate, and a pin hole is opened at the rear end of the plywood and is hinged to the rear mounting hole through a pin. Three arc-shaped notches are provided at the bottom of the plywood. When the locking plate is completely buckled on the mounting plate, the arc-shaped notch can cooperate with the corresponding notch of the adjusting slide slot to lock the pin in the pin mounting seat at the lower end of the support rod, which plays a positioning role. The top of the locking plate is provided with a slide slot hole and a slide pin slot. The locking plate slide pin can slide in the slide slot hole and slide to the slide pin slot to be locked and positioned. The front end of the locking plate slide pin cooperates with the slide pin hole.

[0004] The multi-gear adjustment anti-collision frame is characterized in that: when the gear adjustment is required, the steps are: 1. Drag the locking plate sliding pin to disengage from the sliding pin hole; 2. Flip and open the locking plate buckled on the mounting plate; 3. Drag the support rod so that the pin shaft connected to the lower end moves along the adjustment slide groove to a suitable notch position; 4. Flip the locking plate so that it buckles the mounting plate; 5. Drag the locking plate sliding pin to pass through the sliding pin hole, and slide the rear end of the locking plate sliding pin to the sliding pin slot for positioning;

[0005] The multi-position adjustable anti-collision frame is characterized in that the angle between the anti-collision arm and the vertical plane can be adjusted to 14°, 26° and 44° by adjusting the position of the pin shaft at the lower end of the support rod.

[0006] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is easy to install, use, maintain and disassemble. The currently common adjustable anti-collision frames are mainly divided into electronically controlled hydraulic drive control and bolt adjustment control. The former is relatively complex in design and has high manufacturing and maintenance costs, while the latter is relatively cumbersome to adjust and requires the cooperation of multiple people to proofread and position. When the utility model is used, it is only necessary to slide and adjust the locking plate sliding pin inserted into the sliding pin hole at the top of the mounting plate, and then open the locking plate buckled on the frame mounting plate, and then push the pin shaft of the pin shaft mounting seat at the lower end of the anti-collision frame traction support rod to slide in the adjusting slide groove of the frame mounting plate. After the pin shaft installed in the pin shaft mounting seat at the lower end of the support rod slides to a suitable notch, the locking plate is buckled, and the locking plate is adjusted to slide the locking plate sliding pin through the sliding pin hole at the upper end of the mounting plate on the top of the frame, and then the locking plate sliding pin small shaft is put into the sliding pin slot for locking and positioning, thus completing the gear shifting operation of the anti-collision frame, which is simple and practical.
