[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] Example 1 Figures 1-2 As shown, this utility model relates to an off-road forklift escape assist device, which is installed on the forklift's front fork assembly. The front fork assembly includes a mast 1, a rack 2, and forks 3 installed on the rack 2. The mast 1 is hinged to the forklift's body 9. The body 9 is also equipped with a tilting cylinder 10 connected to the mast 1. The key feature is that the assist device includes a pin insert 4 and a limiting block 5. The pin insert 4 is installed on the rack 2, and the limiting block 5 is installed on the mast 1. The pin insert 4 has the freedom to abut against the limiting block 5. The pin insert 4 and the limiting block 5 abut against each other to restrict the rack 2 from moving upward along the mast 1.

[0025] When the forklift is working normally or traveling, the pin 4 separates from the limit block 5, and the rack 2 can move up and down normally along the mast 1; when the forklift tires are stuck, the pin 4 is pulled up, so that the pin 4 abuts against the side wall of the mast 1, such as Figure 3 As shown, at this time, there is a gap between the lower end of the limiting block 5 and the pin plug 4, which facilitates the movement of the pin plug 4 towards the lower end of the limiting block 5; Figures 4-5 As shown, the tilting cylinder 10 extends, the mast 1 swings downward along its hinge axis, the fork 3 is located on the front side of the mast 1, the fork 3 inserts into the pit in front or contacts the hard ground, the fork 3 is subjected to force and generates relative movement with the mast 1, the pin insert 4 abuts against the limit block 5, the limit block 5 prevents the rack 2 and fork 3 from continuing to generate relative movement with the mast 1, the position between the rack 2, fork 3 and mast 1 is fixed, the fork 3 serves as the front fulcrum of the forklift and the rear wheel of the forklift serves as the rear fulcrum, which can make the front wheel of the forklift lift up and separate from the ground, thereby achieving rapid self-rescue, without waiting or relying on other vehicles to tow for extrication, effectively saving extrication time; adding this auxiliary device to the forklift can effectively improve the self-rescue capability of the forklift and make the forklift more adaptable to harsh ground conditions.

[0026] Further, the pin plug 4 is hingedly arranged on the shelf 2, and two groups of mounting plates are arranged on the left and right sides of the shelf 2 respectively, the pin plug 4 is hinged with the shelf 2 by means of the mounting plates, the hinging shaft of the pin plug 4 is arranged in parallel with the width direction of the forklift, and the pin plug 4 has the freedom of swinging to abut against the portal 1 by means of the hinging shaft; in the normal state, the pin plug 4 is horizontally arranged on the upper end of the shelf 2, so that the shelf 2 can normally ascend and descend along the portal 1; when the tire of the forklift is trapped, the pin plug 4 swings upward to abut against the side wall of the portal 1, the upper end of the pin plug 4 is located below the limiting block 5, the inclined oil cylinder 10 extends to press down the portal 1, and the pin plug 4 abuts against the limiting block 5, so that the fork 3 can serve as the fulcrum of the forklift. The left and right ends of the shelf 2 are respectively provided with the pin plug 4, the stress between the portal 1 and the shelf 2 is dispersed, and the stability between the front fork assembly is improved.

[0027] The auxiliary device further comprises a fixing member, the fixing member fixes the pin plug 4 on the shelf 2, in the embodiment, the fixing member is a fixing bolt 6, the pin plug 4 is provided with a through hole, the shelf 2 is provided with a threaded hole, the fixing bolt 6 is screwed through the through hole and the threaded hole, and the fixing bolt 6 fixes the pin plug 4 on the shelf 2. In the normal state, one end of the pin plug 4 is fixedly connected with the shelf 2 by means of the fixing bolt 6, so that the pin plug 4 is prevented from swinging, vibrating, generating noise or being damaged at will, and the pin plug 4 is also prevented from swinging automatically to below the limiting block 5 to hinder the lifting of the shelf 2 due to vibration of the forklift; when the forklift is trapped, the fixing bolt 6 is removed, and then the pin plug 4 can swing along the hinging shaft.

[0028] Further, when the pin plug 4 abuts against the limiting block 5, the pin plug 4 is arranged between the portal 1 and the shelf 2, so that the stress between the portal 1 and the shelf 2 is further stabilized, and the support performance of the shelf 2 on the portal 1 is improved.

[0029] Preferably, a plurality of limiting blocks 5 are arranged on the portal 1, the limiting blocks 5 are sequentially and spacedly arranged along the height direction of the portal 1, and multiple levels of limiting are formed on the portal 1, so that the height of the shelf 2 can be adjusted according to the road conditions, that is, the pin plug 4 is matched with limiting blocks 5 of different heights, when the ground is greatly undulating, the setting height of the shelf 2 on the portal 1 is high, and the pin plug 4 can be matched with the limiting block 5 at a higher position when the forklift is trapped; when the ground is relatively flat, the setting height of the shelf 2 on the portal 1 can be reduced, and the pin plug 4 can be matched with the limiting block 5 at a lower position when the forklift is trapped, so that the downward angle of the portal 1 is reduced, and the adaptability of the forklift to complex ground conditions is further improved.

[0030] Preferably, the auxiliary device further comprises an auxiliary plate 7, as shown in Figure 6As shown, the auxiliary plate 7 is arranged below the fork 3 and is hinged with the fork 3, the hinge shaft of the auxiliary plate 7 is perpendicular to the upper surface of the fork 3, and the auxiliary plate 7 is further fixed with the fork 3 by means of the fastening bolt 8; in the normal state, the fastening bolt 8 extends downward from the upper surface of the fork 3 and is connected with the auxiliary plate 7, and the fastening bolt 8 fixes the auxiliary plate 7 with the fork 3; when the forklift tire sinks into the mud or loose soil, the mud is serious, the sinking degree of the fork 3 is serious, and effective support cannot be formed only by relying on the fork 3, the fastening bolt 8 is removed, and the auxiliary plate 7 is rotated along the hinge shaft thereof, as shown in Figure 7 As shown, the auxiliary plate 7 and the fork 3 are in a cross structure, and when the portal frame 1 is pressed downward, the arrangement of the auxiliary plate 7 increases the contact area of the front fork assembly with the soil, so that the stress of the soil is evenly dispersed, the auxiliary plate 7 and the fork 3 form effective support in contact with the soil, and the front wheel of the forklift can be separated from the soil, which is convenient for the forklift to escape from the trouble.

[0031] Embodiment 2, as shown in Figure 8 The embodiment is basically the same as embodiment 1, and the difference is that the fixing member in the embodiment is a magnet 11, the magnet 11 is adsorbed on the upper end of the rack 2, and the pin plug 4 is overlapped on the magnet 11 and is fixed by the magnet 11, when the pin plug 4 needs to be swung, the pin plug 4 is directly pulled to separate the pin plug from the magnet 11, the fixing and moving of the pin plug 4 on the rack 2 are more easily converted, and the operation is more convenient.
