Description
Technical Field
[0001] The utility model relates to the technical field of telescopic forks, and particularly relates to a telescopic fork with adjustable fork spacing. Background Art
[0002] Telescopic forks are widely used in industries such as warehousing, papermaking, packaging, printing, tobacco, household appliances, wine and beverages, wool and cotton textiles, port terminals, railways, bicycle manufacturing, iron and steel smelting, chemical engineering, and construction. Most current telescopic forks are double-fork type, and the telescopic forks are inserted from the bottom of the pallet to pick up goods;
[0003] With the increasing complexity and diversification of logistics operations, the specifications and sizes of goods have become more diverse. In this case, using a fork tool with a fixed fork spacing often cannot effectively meet the handling requirements of various goods. When the size of the goods is small, an overly large fixed fork spacing may result in an inability to stably lift the goods, increasing the risk of the goods falling. When the size of the goods is large, a too small fork spacing cannot smoothly insert under the goods for handling, which leads to problems such as low handling efficiency, damaged goods, and inconvenient operation. Therefore, we introduce a telescopic fork with adjustable fork spacing. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide a telescopic fork with adjustable fork spacing, which can effectively solve the problems in the background art.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A telescopic fork with adjustable fork spacing includes a mounting plate. Two support grooves are opened in the middle of the upper end of the mounting plate. Fixing plates are fixedly connected to the left and right parts of the rear end of the mounting plate respectively. Through holes are opened in the upper parts of the front ends of the two fixing plates. A left side plate is fixedly connected to the left part of the upper end of the mounting plate, and a right side plate is fixedly connected to the right part of the upper end of the mounting plate. A control device is inserted and installed at the left end of the left side plate. A connecting plate is fixedly connected between the left side plate and the right side plate at the rear. Slide grooves are opened in the left and right parts of the front end of the connecting plate.
[0007] The control device includes a rotary motor. The output end of the rotary motor is fixedly installed with a left ball screw. A fixed head is fixedly connected to the right end of the left ball screw. A right ball screw is fixedly connected to the right end of the fixed head. Transmission components are threadedly connected to the outer surfaces of both the left ball screw and the right ball screw. The right end of the rotary motor is fixedly connected to the left end of the left side plate, and the output end of the rotary motor penetrates the left end of the left side plate and extends to the right end of the left side plate.
[0008] Preferably, the left ball screw and the right ball screw are distributed in a left-right mirror image, and the right end of the right ball screw is movably connected to the left end of the right side plate through a bearing.
[0009] By adopting the above technical solution: the left ball screw and the right ball screw are distributed in a left-right mirror image, so that when adjusting the fork spacing, the forces on the left and right sides are more evenly balanced, which can reduce the structural deformation and wear caused by uneven unilateral force, thereby extending the service life of the telescopic fork.
[0010] Preferably, the transmission assembly includes a ball screw block. A slider is fixedly connected to the rear end of the ball screw block, a limit block is fixedly connected to the rear end of the slider, a support plate is fixedly connected to the lower end of the ball screw block, a connection assembly is fixedly connected to the front end of the ball screw block, and the inner wall surface of the left ball screw block is threadedly connected to the outer surface of the left ball screw.
[0011] By adopting the above technical solution: the threaded connection between the ball screw block and the left ball screw can achieve high-precision linear motion, ensure the accuracy of fork spacing adjustment, and meet the precise handling requirements for different cargo sizes.
[0012] Preferably, the slider is movably sleeved in the corresponding chute, and the lower part of the support plate is movably sleeved in the corresponding support groove.
[0013] By adopting the above technical solution: the slider slides in the chute, providing a stable guide for the movement of the ball screw block, preventing it from shifting or shaking during the movement, thereby improving the stability and reliability of the telescopic fork during operation. The support plate moves in the support groove, providing additional support for the entire transmission assembly, enabling the ball screw block to maintain balance when carrying goods and reducing the burden on the ball screw.
[0014] Preferably, the connection assembly includes a connection block. A fork body is fixedly connected to the front end of the connection block. A plurality of anti-slip grooves are formed in the upper end of the fork body. The rear end of the connection block is fixedly connected to the front end of the ball screw block.
[0015] By adopting the above technical solution: the plurality of anti-slip grooves at the upper end of the fork body increase the friction force with the goods. When handling goods, it can effectively prevent the goods from slipping, improving the safety and stability of the handling process.
[0016] Preferably, the plurality of anti-slip grooves are distributed at equal distances in pairs, and the front end of the fork body is provided in a flat shape.
[0017] By adopting the above technical solution: the front end of the fork body is provided in a flat shape, which can better insert into the bottom of the goods, is applicable to various shapes and sizes of goods, and improves the versatility of the telescopic fork.
[0018] Compared with the prior art, the present utility model has the following beneficial effects:
[0019] 1. In this utility model, when the rotary motor operates, its output end drives the left ball screw to rotate. Since the left ball screw and the right ball screw are connected by a fixed head, the rotation of the left ball screw will synchronously drive the right ball screw to rotate. When the left ball screw rotates, the ball screw block on the left side will move left or right according to the rotation direction. Since the left ball screw and the right ball screw are mirror - distributed, the ball screw block on the right side will move in the opposite direction to the ball screw block on the left side, which can quickly adapt to the handling requirements of goods of different sizes, reduce the time waste caused by replacing different - sized forks, and thus significantly improve the efficiency of goods handling.
[0020] 2. When this utility model is not in use, the fork spacing can be adjusted to the minimum, saving storage space and being beneficial to the space planning and utilization of the warehouse or workplace. BRIEF DESCRIPTION OF THE DRAWINGS
