[0036] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the utility model is not limited to the following specific embodiments.

[0037] Embodiment 1:

[0038] refer to Figure 1-4 A side shifter includes a fixed frame 11, a sliding frame 21, and a driving member 12.

[0039] The sliding frame 21 is provided with a sliding groove 22 with an opening downward, and the sliding frame 21 is fixedly connected with a protrusion 24 located at the opening of the sliding groove 22. The sliding frame 21 is detachably installed with a wear-resistant lining plate 23, and the wear-resistant lining plate 23 is in contact with the inner wall of the sliding groove 22. The fixed frame 11 is detachably installed with a support plate 13, and the support plate 13 is in contact with the wear-resistant lining plate 23, and the support plate 13 is slidably connected with the wear-resistant lining plate 23. The driving member 12 is a hydraulic cylinder, and the driving member 12 is fixedly installed on the fixed frame 11, and the output end of the driving member 12 is connected to the sliding frame 21. There are two wear-resistant lining plates 23, which are arranged along the length direction of the support plate 13, and the two wear-resistant lining plates 23 are in contact with each other front and back. There are two locking blocks 32, and the two locking blocks 32 correspond to the two wear-resistant lining plates 23 one by one. The length of the support plate 13 is greater than half of the distance between the two locking blocks 32 and less than the length of the wear-resistant lining plate 23.

[0040] The support plate 13 includes a connecting section 14, a supporting section 15 and a convergent section 16. The supporting section 15 is located between the connecting section 14 and the convergent section 16. The connecting section 14 is connected to the fixing frame 11. The end of the convergent section 16 away from the supporting section 15 is inclined toward the direction close to the connecting section 14. The protrusion 24 is engaged with the convergent section 16. The sliding frame 21 is provided with a slot, and the end of the wear-resistant lining plate 23 close to the connecting section 14 is engaged in the slot. The sliding frame 21 is fixedly connected with a positioning step plate 31, and the positioning step plate 31 is engaged with the wear-resistant lining plate 23.

[0041] The sliding frame 21 is detachably connected with a locking block 32, which is located at one end of the wear-resistant lining plate 23 away from the fixing member, and the locking block 32 is installed with a screw 33, which is threadedly connected with the sliding frame 21. The screw 33 is inserted through the positioning step plate 31. A gap 34 is provided between the positioning step plate 31 and the locking block 32. The locking block 32 is fixedly connected with a positioning pin 35, and the sliding frame 21 is provided with a positioning hole 36 that cooperates with the positioning pin 35, and the positioning pin 35 is inserted through the wear-resistant lining plate 23.

[0042] This embodiment has the following advantages:

[0043] The fixed frame 11 and the sliding frame 21 play a role of structural support. The fixed frame 11 is used to be connected to the forklift, and the sliding frame 21 is used to install the fork. The sliding frame 21 and the fixed frame 11 are connected through the wear-resistant lining plate 23 and the support plate 13. The support plate 13 provides support force to the wear-resistant lining plate 23 so that the wear-resistant lining plate 23 slides on the support plate 13, so that the wear-resistant lining plate 23 can block the sliding frame 21, effectively reducing the wear of the sliding frame 21, and the support plate 13 can block the fixed frame 11, effectively reducing the wear of the fixed frame 11. When the wear-resistant lining plate 23 and the support plate 13 are worn to a large extent, the worn wear-resistant lining plate 23 and the support plate 13 can be removed and replaced with new wear-resistant lining plate 23 and the support plate 13, so that the structural stability of the side shifter can be ensured, and the side shifter can be prevented from being damaged and broken after long-term use, achieving the advantage of better reliability.

[0044] After the support plate 13 is inserted into the sliding groove 22 , the support plate 13 is clamped by the protrusion 24 to prevent the support plate 13 from accidentally falling off from the sliding groove 22 , thereby improving the structural stability between the wear-resistant lining plate 23 and the support plate 13 .

[0045] The protrusion 24 is engaged with the side of the support section 15 away from the support section 15 , so that the support plate 13 can be clamped by the protrusion 24 , thereby preventing the support plate 13 from accidentally falling off from the sliding groove 22 .

[0046] The wear-resistant lining plate 23 is inserted into the slot, which can play a role in positioning and supporting the wear-resistant lining plate 23 and improve the stability of the wear-resistant lining plate 23 .

[0047] The two wear-resistant lining plates 23 can increase the movement stroke between the sliding frame 21 and the fixed frame 11, thus achieving an effect of facilitating use.

[0048] The positioning step plate 31 is clamped with the wear-resistant lining plate 23 , so as to position and support the wear-resistant lining plate 23 and improve the stability of the wear-resistant lining plate 23 .

[0049] The locking block 32 is installed on the sliding frame 21, and the wear-resistant lining plate 23 is clamped by the locking block 32, and then the locking block 32 is fixed to the sliding frame 21 by the screw 33, so as to realize the function of fixing the wear-resistant lining plate 23 on the sliding frame 21. When the wear-resistant lining plate 23 needs to be removed, the screw 33 is loosened and the locking block 32 is removed, so that the wear-resistant lining plate 23 can be removed from the sliding frame 21, and the function of the sliding frame 21 being detachably connected is realized.

[0050] The screw 33 passes through the positioning step plate 31 so that the screw 33 can be engaged with the positioning step plate 31 . The positioning step plate 31 abuts against the screw 33 , thereby providing positioning and support for the screw 33 .

[0051] The gap 34 between the positioning step plate 31 and the locking block 32 prevents the locking block 32 from being stuck by the positioning step plate 31 , thereby ensuring that the locking block 32 can press the wear-resistant lining plate 23 .

[0052] By passing the positioning pin 35 through the wear-resistant lining plate 23, the wear-resistant lining plate 23 can be positioned to ensure that the two wear-resistant lining plates 23 can be spliced ​​and aligned. The positioning pin 35 is inserted into the positioning hole 36 to ensure that the positioning pin 35 is accurately positioned to ensure the accuracy of the positions of the wear-resistant lining plate 23 and the locking block 32.

[0053] In the initial state, the support plate 13 moves to the middle position, and the two wear-resistant lining plates 23 are in contact with the support plate 13. Figure 2 When the locking block 32 is not removed, since the length of the support plate 13 is greater than the distance between the two locking blocks 32, when the support plate 13 slides to the limit position with the wear-resistant lining plate 23, the two locking blocks 32 can block the support plate 13, preventing the support plate 13 from moving to a state of being separated from one of the wear-resistant lining plates 23, so that both the wear-resistant lining plates 23 can be clamped by the support plate 13 and the locking block 32, so that the two wear-resistant lining plates 23 remain stable. When the locking block 32 is removed, since the length of the support plate 13 is smaller than the length of the wear-resistant lining 23, the support is moved to the extreme position in the direction of the removed locking block 32. The support plate 13 can slide to a farther position without the locking block 32 blocking it, thereby enabling the support plate 13 to be disengaged from the wear-resistant lining 23 on the side opposite to the movement direction, and then the wear-resistant lining 23 on the side opposite to the movement direction of the support plate 13 can be removed. The wear-resistant lining 23 can be replaced without removing the support plate 13, thereby facilitating the replacement of the wear-resistant lining 23.
