It is widely used in ports, stations, airports, warehouses and various logistics centers. Common forklifts are mainly composed of: power unit, transmission system, steering system, working device, hydraulic system and electrical equipment. The hydraulic system includes: lifting hydraulic cylinder, tilting hydraulic cylinder, etc. The forklift tilt hydraulic cylinder is mainly used to control the tilt of the forklift.

[0003] The forklift tilt cylinder support is a type of component used to limit the assembly of the tilt cylinder. Currently, the common forklift tilt cylinder is generally assembled on the forklift body by welding. When assembling and welding the forklift tilt cylinder support, the forklift tilt cylinder support is generally positioned by marking on the forklift body.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, a forklift tilt cylinder support positioning mechanism in one embodiment of the utility model includes: a positioning base 1, a supporting positioning component 2, and an auxiliary positioning component 3.

[0033] like Figure 1 As shown, a pair of fixed bottom plates 101 are integrally formed at the bottom of the positioning base 1. The fixed bottom plates 101 are provided to improve the assembly stability of the positioning base 1.

[0034] Specifically, a pair of assembly limiting holes are drilled on each of the pair of fixed base plates 101. The assembly limiting holes are drilled to facilitate locking and fixing of the fixed base plates 101.

[0035] like Figure 1 to Figure 2 As shown, the supporting and positioning assembly 2 is fixedly assembled on the top of the positioning base 1, and the supporting and positioning assembly 2 includes a supporting fork 201, and the supporting fork 201 is slidably assembled on the top of the positioning base 1. The supporting fork 201 plays a role of supporting and fixing a pair of limiting rings 202.

[0036] Preferably, the supporting fork 201 is concavely arranged, and the supporting fork 201 is arranged in cooperation with the driving block 203. The supporting fork 201 is used to assemble and fix a pair of limit rings 202, and at the same time, the supporting fork 201 can provide a rotational operating space for the driving block 203.

[0037] Specifically, a storage and limiting groove is opened in the positioning base 1. The lifting push rod 206 is stored and limited by the storage and limiting groove.

[0038] like Figures 2 to 5 As shown, a lifting push rod 206 is slidably mounted in the storage limit groove, and the lifting push rod 206 is fixedly mounted below the supporting fork 201. The lifting push rod 206 plays the role of supporting, fixing and lifting control for the supporting fork 201.

[0039] like Figures 4 to 5 As shown, both sides of the positioning base 1 are threadedly connected with locking bolts 207, and the locking bolts 207 are arranged in cooperation with the lifting push rod 206. By controlling the rotation of the locking bolts 207, the lifting push rod 206 is locked and fixed, thereby improving the stability of the height adjustment control of the supporting fork 201.

[0040] like Figures 1 to 3 As shown, a pair of limiting rings 202 are fixedly connected above the supporting fork 201. The pair of limiting rings 202 play a role of supporting and limiting the driving block 203, thereby ensuring the running stability of the driving block 203.

[0041] like Figures 1 to 3 As shown, a pair of limiting rings 202 are rotatably connected with a driving block 203. The driving block 203 supports, fixes and rotates a pair of limiting threaded rods 204.

[0042] like Figures 1 to 3 As shown, both sides of the driving block 203 are fixedly connected with limit threaded rods 204, which penetrate the limit ring 202 and are rotatably connected to the limit ring 202. The limit threaded rods 204 play the role of locking and limiting the positioning member 205 and controlling its movement.

[0043] like Figures 1 to 3 As shown, the ends of a pair of limiting threaded rods 204 that are separated from each other are both threadedly connected with positioning members 205. The positioning members 205 are used to support and position the tilting cylinder support of the forklift to be assembled.

[0044] like Figure 1 to Figure 2 As shown, the positioning member 205 is composed of a positioning plate 2051 and a supporting shaft 2052. The supporting shaft 2052 is fixedly assembled on the side of the positioning plate 2051 away from the limiting ring 202. The positioning plate 2051 supports and limits the tilting cylinder support. The supporting shaft 2052 intersects and limits the tilting cylinder support.

[0045] like Figures 1 to 3 As shown, a plurality of evenly distributed guide slide bars 208 are fixedly connected to one side of the positioning plate 2051 close to the limiting ring 202, and a plurality of shrinkage limiting cavities are excavated in the limiting ring 202, and the plurality of guide slide bars 208 are slidably assembled in the shrinkage limiting cavities. The plurality of guide slide bars 208 slide in the shrinkage limiting cavities to play a role of sliding limiting on the positioning plate 2051, thereby improving the stability of the position adjustment of the positioning member 205.

[0046] like Figure 1 As shown, the auxiliary positioning assembly 3 is slidably assembled on one side of the positioning base 1, and the auxiliary positioning assembly 3 includes a bottom positioning plate 301, which is slidably assembled under the supporting fork 201, and the lower surface of the bottom positioning plate 301 is in the same horizontal plane as the bottom surface of the positioning base 1. The bottom positioning plate 301 is used to assist in positioning the forklift tilt cylinder support to be assembled.

[0047] Among them, guide grooves are excavated under the positioning base 1 and the pair of fixed base plates 101, and the guide slide plate 302 is assembled and slidably guided through the guide grooves.

[0048] like Figure 1 As shown, a guide slide plate 302 is slidably mounted in the guide slot, so as to facilitate the bottom positioning plate 301 to play a role of sliding guide through the mutual cooperation between the guide slide plate 302 and the guide slot.

[0049] like Figure 1 As shown, a fixing bolt 303 is fixedly connected between the guide slide plate 302 and the bottom positioning plate 301. The bottom positioning plate 301 and the guide slide plate 302 are locked and fixed by the fixing bolt 303.

[0050] like Figures 1 to 7 As shown, when in use, the positioning base 1 is placed on the forklift body, and the fixed base plate 101 is assembled and fixed through the assembly limiting holes, thereby fixing and limiting the positioning base 1. Subsequently, the positioning member 205 is used to support and limit the forklift tilt cylinder support to be assembled.

[0051] When the positioning member 205 supports and limits the forklift tilt cylinder support, the locking state of the lifting push rod 206 is released by controlling the rotation of the locking bolt 207, and the height of the supporting fork 201 is adjusted by controlling the extension of the lifting push rod 206.

[0052] At the same time, the limiting threaded rod 204 can be driven to rotate by controlling the rotation of the driving block 203. At this time, the positioning member 205 moves under the guiding and limiting action of the internal and external threads and the guide slide bar 208. The spacing between the pair of positioning members 205 is adjusted to be the same as the tail end of the forklift tilt cylinder by controlling the rotation of the driving block 203. In addition, the bottom positioning plate 301 can be used to assist in positioning the bottom of the forklift tilt cylinder support. After positioning, the forklift tilt cylinder support can be welded and assembled.

[0053] After the assembly is completed, the positioning member 205 releases the supporting state of the forklift tilt cylinder support by controlling the driving block 203 to rotate in the opposite direction, and then the positioning base 1 can be disassembled by disassembling the fixed base plate 101.

[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
