[0006] The positioning shaft has multiple positioning slots, and the upper gantry support of the lifting system is installed in the positioning slots.

[0007] The positioning shaft is fitted with end caps at both ends, and the end caps are fixedly mounted on the mounting base by the first bolt.

[0008] The mounting base has a mounting hole, and a pin is installed in the mounting hole. The pin passes through the mounting hole and is inserted into the tilting cylinder support hole on the lifting system.

[0009] The support assembly includes: a mounting block, which is fixedly mounted on the base, and a screw is mounted on the mounting block.

[0010] The base is provided with a threaded hole, the screw is installed in the threaded hole, and a nut for locking and controlling the length of the screw is installed on the screw; the screw is supported and installed below the positioning shaft.

[0011] The positioning shaft is equipped with a support cover for fixing the lifting system.

[0012] The base frame is equipped with an oil receiving tray.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model provides a clamping fixture for debugging a forklift lifting system. By setting a positioning shaft that matches the lifting system and fixing installation components, the assembled lifting system to be debugged can be manually hoisted onto the clamping fixture. The upper mast support of the lifting system is positioned in the positioning shaft groove of the clamping fixture. The support cover is connected to the upper mast support of the lifting system by bolts. Then, a pin is inserted into the hole on the mounting base. The pin passes through the inclined cylinder support hole on the lifting system. After the lifting system is completely fixed on the clamping fixture, the pipeline is connected, and the lifting, synchronization, clearance, etc. of the lifting system are debugged, which facilitates subsequent installation and inspection work and greatly improves work efficiency.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0025] like Figure 1-8 As shown, this utility model patent provides a clamping fixture for debugging a forklift lifting system, including: a base 1, a mounting seat 2 mounted on the base 1, a positioning shaft 3 for positioning the lifting system 8 mounted on the mounting seat 2, and a support assembly 6 mounted on the base 1, the top of the support assembly 6 being in perpendicular contact with the positioning shaft 3. The base 1 is fixed to the ground by expansion bolts 11.

[0026] like Figure 4 As shown, the positioning shaft 3 has multiple positioning slots 3-1, and the upper gantry support of the lifting system 8 is installed in the positioning slots 3-1. The positioning slots 3-1 are used to position the lifting system 8 with different gantry support openings, and the upper gantry support of the lifting system 8 is installed on the positioning shaft 3 slots.

[0027] Specifically, end caps 12 are installed at both ends of the positioning shaft 3. The end caps 12 are fixedly installed on the mounting base 2 by first bolts 13, used to limit the axial position of the positioning shaft 3. The positioning shaft 3 has support caps 4 for fixing the gantry support 8-2 of the lifting system 8, such as... Figure 5 , 6 .

[0028] The mounting base 2 has a mounting hole, and a pin 5 is installed in the mounting hole. The pin 5 passes through the mounting hole and is inserted into the hole of the tilting cylinder support 8-1 on the lifting system 8. Figure 7 As shown, for lifting systems 8 with different positions from the hole position of the tilt cylinder support 8-1 to the semi-circular center position of the gantry support 8-2, the positioning holes 2-1 at different positions on the mounting base 2 are inserted into the pin shaft 5 to ensure that the lifting system 8 is in a vertical state.

[0029] like Figure 8 As shown, the support assembly 6 includes: a mounting block 6-1, which is fixedly mounted on the base 1, and a screw 6-3 is mounted on the mounting block 6-1. The base 1 is provided with a threaded hole 10, and the screw 6-3 is installed in the threaded hole 10. A nut 6-2 for locking and controlling the length of the screw 6-3 is installed on the screw 6-3; the screw 6-3 is supported and mounted below the positioning shaft 3.

[0030] In addition, the base 1 frame is equipped with an oil receiving tray 7, and the oil flows into the oil receiving tray 7 through the hole on the mounting base 2.

[0031] The end cap 12 is mounted on the mounting base 2 by the first bolt 13, which is used to limit the axial position of the positioning shaft 3.
