Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fork truck, especially a fork truck lengthening tooth. BACKGROUND

[0002] The company workshop needs to prepare a lot of corresponding equipment and raw materials in the production process, and also needs to prepare a warehouse to store these materials. The equipment or raw materials needed in the production process of the workshop generally cannot be pushed at the warehouse entrance, and generally need to be forked out of the warehouse by a forklift. The fork arm of the forklift is short, and if the materials are stored in the deep part of the warehouse, the existing fork arm of the forklift cannot reach the designated position. At this time, the materials on the outside need to be moved first, and then the materials inside the warehouse need to be moved out. Finally, the materials that have been moved out need to be put back into the warehouse. In this process, a lot of time and manpower are often consumed, causing an increase in the production cost of the company. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a fork truck lengthening tooth.

[0004] To solve the above technical problems, the technical scheme of the utility model is as follows: a fork truck lengthening tooth, which is characterized by comprising square tubes, connecting plates, high supports, low supports, and a lifting arm.

[0005] The square tubes are two in number and are horizontally arranged, and the square tubes have passages for accommodating the insertion of the fork arm of the forklift.

[0006] The connecting plates are longitudinally arranged between the two square tubes on both sides of the length of the square tubes, and the square tubes and the connecting plates form a bottom rectangular insertion structure.

[0007] The high supports are arranged on one side of the length of the bottom rectangular insertion structure.

[0008] The low supports are arranged on the other side of the length of the bottom rectangular insertion structure.

[0009] The lifting arm is horizontally arranged vertically above the center line of the wide side of the bottom rectangular insertion structure, and is welded and fixed to the high supports by a first connecting piece and to the low supports by a second connecting piece. The length of the lifting arm is greater than the length of the square tube.

[0010] Further, the length of the lifting arm is 3-4 times the length of the square tube, so that the structure can be applied to lifting materials in the deep part of the warehouse.

[0011] Furthermore, an oblique brace is fixed between the bottom rectangular plug-in structure and the middle part of the boom, the top end of the oblique brace is fixedly connected to the middle part of the boom, and the bottom end is fixedly connected to the bottom rectangular plug-in structure through a fixed plate, and the fixed plate is longitudinally fixed on the bottom rectangular plug-in structure on the side of the low bracket away from the high bracket, thereby improving the structural stability when using the boom to lift materials.

[0012] Furthermore, the high bracket includes a long diagonal rod and a main fixed block. There are two long diagonal rods, which are distributed in an eight-shaped shape on two square tubes. The main fixed block is fixed at the top position between the two long diagonal rods, and one side of the boom is fixed on the bottom end of the main fixed block.

[0013] Furthermore, the high bracket also includes a first fixing tube, and the first fixing tube is fixed between both sides of the boom and the main fixing block, thereby increasing the fixing area between the boom and the first fixing tube and improving the structural stability.

[0014] Furthermore, the low bracket includes two short diagonal bars and a main support block. The short diagonal bars are distributed in an eight-shaped pattern on two square tubes. The main support block is fixed between the two short diagonal bars and is located on the bottom end of the boom.

[0015] Furthermore, the low bracket also includes a second fixing tube, and a second fixing tube is fixed between both sides of the boom and the main support block, thereby increasing the fixing area between the boom and the second fixing tube and improving the structural stability.

[0016] Furthermore, a well-shaped reinforcement is fixed between the low bracket and the high bracket, thereby improving the structural stability when the boom is used to lift materials.

[0017] Furthermore, a plurality of limit blocks are fixed to the top of the middle portion of the boom, which can prevent the hoisting hoist from sliding and falling off during the process of hoisting materials using the hoisting hoist, thereby avoiding damage to the materials.

[0018] The advantages of the present invention are:

[0019] 1. The connection between the utility model and the forklift is achieved by extending the forklift fork arm into the channel of the two square tubes, and then the lifting arm is used to extend into the materials deep in the warehouse, and the lifting of the materials is achieved by using the lifting hoist, which avoids the situation that the existing forklift fork arm is too short to directly lift the materials deep in the warehouse. At the same time, it can save manpower and time for transporting materials and reduce the company's production costs.

[0020] 2. A diagonal brace is fixed between the bottom rectangular plug-in structure and the middle of the boom. The bottom end of the diagonal brace is fixedly connected to the bottom rectangular plug-in structure through a fixed plate, thereby improving the structural stability when using the boom to lift materials.

[0021] 3. First fixing tubes are fixed between both sides of the boom and the main fixing block to increase the fixing area between the boom and the first fixing tubes and improve structural stability.

[0022] 4. A well-shaped reinforcement is fixed between the low bracket and the high bracket to improve the structural stability when lifting materials using the boom.

[0023] 5. There are also multiple limit blocks fixed on the top of the middle part of the boom, which can prevent the hoisting hoist from sliding and falling off during the process of hoisting materials, thereby avoiding damage to the materials.

[0024] 6. One side of the boom is at the bottom of the main fixed block, the middle is at the top of the main support block, and the other side is used to lift materials. The lever is used to increase the counterweight, so that the boom can lift more weight. BRIEF DESCRIPTION OF THE DRAWINGS
