The engine hood is very long in the front-back direction, and the rear part is a tipping cylinder and a tipping shaft. The engine hood rotates around the tipping shaft. When the engine hood is tipped, the tipping cylinder and the tipping shaft cooperate to tip the engine hood. Under the action of the tipping cylinder, the engine hood is placed in a horizontal position. At this time, the tipping cylinder is always under force, and long-term use will reduce the service life of the tipping cylinder; there is no fixed point at the front of the engine hood, and the fixed point at the tail is too far away. Due to gravity and rotation, the engine hood will swing left and right. Content of the Utility Model

[0024] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations for the present utility model. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.
[0025] The existing hood of the loader is an openable structure for the convenience of engine maintenance and repair. The hood is very long in the front-back direction. The rear part is a flip cylinder and a flip shaft, and the hood rotates around the flip shaft. When the hood flips, the flip cylinder and the flip shaft cooperate to flip the hood. The hood is placed horizontally under the action of the flip cylinder. At this time, the flip cylinder is always stressed, and long-term use will reduce the service life of the flip cylinder; there is no fixed point at the front of the hood, and the fixed point at the tail is too far away. Due to gravity and rotation, the hood will swing left and right.
[0026] The limiting device of the present utility model can achieve limiting when the hood flips. The limiting devices are arranged in pairs at both ends of the hood. When the hood touches the limiting device, the gravity of the hood is transferred from the flip cylinder to the limiting plate and the flip shaft, releasing the stress on the flip cylinder.
[0027] The following will combine the attached drawings to make a detailed description of the present utility model. A limiting device for a flip hood disclosed in this embodiment, as Figure 1 shown, includes a first mounting plate 3. A first limiting block 1 is arranged at the upper end of the first mounting plate 3. A second mounting plate 4 is arranged at one end of the first mounting plate 3. A second limiting block 2 is arranged on the second mounting plate 4, and the upper end surface of the second limiting block 2 is an inclined surface; First oblong holes 13 are symmetrically arranged on the first mounting plate 3. A third mounting plate 5 is arranged at the lower end of the first mounting plate 3. Second oblong holes 14 are symmetrically arranged on the third mounting plate 5.
[0028] The first limit block 1 limits the hood in the vertical direction after the hood is flipped, and the second limit block 2 limits the hood in the horizontal direction after the hood is flipped. At the same time, the upper end surface of the second limit block 2 is an inclined surface, and the inclined surface of the second limit block 2 plays a guiding role when the hood is flipped. When the hood is flipped to the horizontal position, the hood frame is provided with an L-shaped limit plate. The bottom of the limit plate contacts the first limit block 1, and the inner side of the limit plate contacts the second limit block 2, thereby releasing the force on the flipping cylinder and serving as the front fixing point of the hood to play a supporting role, reducing the left and right swaying of the hood, thereby ensuring the service life of the flipping cylinder and making the hood easy to flip.
[0029] First round holes 11 are symmetrically arranged at the upper end of the first limit block 1, and second round holes 12 are symmetrically arranged on the second limit block 2. The second round holes 12 are arranged on the side surface of the second limit. The first round holes 11 and the second round holes 12 are round holes with counterbores for installing countersunk head screws.
[0030] Threaded holes 15 are symmetrically arranged on the third mounting plate 5, and the threaded holes 15 are located at the lower end of the first long round hole 13. The upper end of the first mounting bolt 7 passes through the first long round hole 13, and the lower end is screwed into the threaded hole 15 to connect the first mounting plate 3 and the third mounting plate 5.
[0031] The first mounting bolt 7 is arranged in the first long round hole 13. The first mounting bolt 7 passes through the first long round hole 13 and the threaded hole 15 in sequence to connect the first mounting plate 3 and the third mounting plate 5. A first gasket 8 is sleeved on the first mounting bolt 7. The upper surface of the first gasket 8 is in close contact with the first mounting bolt 7, and the lower surface of the first gasket 8 is in close contact with the first mounting plate 3.
[0032] As Figure 2 shown, a second mounting bolt 9 is arranged in the second long round hole 14, and the second mounting bolt 9 passes through the second long round hole 14. A second gasket 10 is sleeved on the second mounting bolt 9. The upper surface of the second gasket 10 is in close contact with the second mounting bolt 9, and the lower surface of the second gasket 10 is in close contact with the third mounting plate 5.
[0033] The first mounting plate 3 and the third mounting plate 5 are connected by the first mounting bolt 7, and the first long round hole 13 and the first mounting bolt 7 cooperate to adjust the position of the limit block in the horizontal direction; the third mounting plate 5 and the corresponding mounting structure are connected by the second mounting bolt 9, and the second long round hole 14 and the second mounting bolt 9 cooperate to adjust the position of the limit block in the vertical direction, thereby being applicable to hoods of multiple models and playing a limiting role in the flipping of hoods of different models, with strong applicability. The first gasket 8 and the second gasket 10 can increase the contact area, reduce the pressure, protect the parts, and prevent loosening.
[0034] When adjusting the horizontal position, unscrew the first mounting bolt 7, move the first mounting plate 3 horizontally. After moving it to the desired position, pass the first mounting screw through the first long circular hole 13, and then screw it into the screw hole, thus completing the horizontal position adjustment; when adjusting the vertical position, unscrew the second mounting bolt 9, move the third mounting plate 5 vertically. After moving it to the desired position, pass the second mounting screw through the second long circular hole 14, and then screw it into the corresponding mounting structure, thus completing the vertical position adjustment.
[0035] The setting of the first gasket 8 makes the connection between the first mounting plate 3 and the third mounting plate 5 more firm, and the setting of the second gasket 10 makes the connection between the third mounting plate 5 and the corresponding mounting position more firm.
[0036] The first mounting plate 3 and the second mounting plate 4 are of an integral structure, and the first mounting plate 3 is detachably connected to the third mounting plate 5. The first limiting block 1 is fixedly connected to the first mounting plate 3, and the second limiting block 2 is fixedly connected to the second mounting plate 4. A rib plate 6 is provided at the lower end of the third mounting plate 5, and the rib plate 6 is fixedly connected to the third mounting plate 5. The rib plate 6 can improve the strength of the third mounting plate 5, enable the third mounting plate 5 to have sufficient bearing capacity, and further serve as a support point for the engine hood to provide support for the front part of the engine hood.
