Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of forklifts, and particularly relates to a side slider mechanism with adjustable clearance and a forklift. Background Art
[0002] With the continuous rise of the logistics industry and the rapid development of social productivity, the demand for efficient and flexible transportation equipment is increasing day by day. In modern warehousing and logistics systems, forklifts play a key role as an important handling tool. Forklifts can quickly transport and stack goods from a designated location to the warehouse shelves, or pick up goods from the shelves and transport them to a designated location, providing convenience and efficiency for warehousing and logistics operations.
[0003] As an important equipment for material handling, the stability and durability of its performance are crucial for improving work efficiency and reducing maintenance costs. Especially, the forklift mast, as a key component for carrying and moving goods, the performance of its roller bearings directly affects the overall performance of the forklift.
[0004] In order to adjust the clearance between the forklift mast and the channel steel, thereby reducing the sway amount of the forklift, and thus ensuring the smoothness and the best stress state during forklift operation. In the prior art, the most commonly used on the forklift mast in the market is the composite roller (refer to Figure 5 ), which is composed of a main roller, a side roller and other components. Both ends of the central axis of the side roller are stuck on the inner wall of the central hole of the main roller. The main roller is responsible for guiding and rolling in the channel steel, and the side roller is responsible for clearance adjustment. Although such a composite roller has a certain effect in terms of guiding and clearance adjustment, due to the side roller being embedded in the main roller, it causes difficulties in maintenance and replacement, significantly increasing the maintenance cost and time consumption.
[0005] Therefore, there is an urgent need to design an institution that can not only reduce the sway amount of the mast, improve the stability of the forklift, but also reduce the maintenance cost to adjust the clearance between the forklift mast and the channel steel. Summary of the Utility Model
[0006] In view of all or part of the deficiencies of the above-mentioned prior art, the purpose of the present utility model is to provide a side slider mechanism with adjustable clearance and a forklift, which can effectively reduce the sway amount of the mast, improve the stability of the forklift, reduce the maintenance cost, improve the operability of the forklift during forklift operation, and thus provide more reliable support for modern efficient warehousing and logistics systems.
[0007] To achieve the above object of the utility model, the present utility model provides the following technical solutions:
[0008] An adjustable clearance side slider mechanism, comprising a side slider, a side slide tube, and an adjusting member. The side slider is connected to the to-be-connected member through the side slide tube. A connection hole is provided on the to-be-connected member. The adjusting member adjusts the clearance between the opposite surfaces of the side slider and the to-be-connected member by cooperating with the connection hole. By independently designing the adjustable clearance side slider mechanism on the corresponding production mechanism, when the mechanism fails, it is convenient for disassembly, repair, and replacement, reducing the maintenance cost of the production mechanism.
[0009] The side slide tube is mechanically connected to the connection hole, and the connection hole is a stepped hole. Mechanical connection refers to the technology of fastening two or more components together physically, which has many advantages such as being able to withstand high loads, being easy to install and disassemble, having low cost, being applicable to various materials, and improving stability. Setting the connection hole as a stepped hole can provide better support and stability through a larger contact area, reduce local stress concentration, thereby improving the strength of the overall structure. The smaller diameter hole section can be used for preliminary positioning, and the larger hole section is used for final fixation, reducing problems caused by improper assembly.
[0010] The adjusting member is a single-head internal hexagonal stud. A threaded hole communicating with the connection hole is provided on the to-be-connected member for threaded cooperation with the adjusting member. The internal hexagonal stud can provide better torque transmission ability, and its design is more compact than that of an external hexagonal bolt, which can save space, has stronger adaptability to narrow areas, and the internal hexagonal stud is not prone to self-loosening or loosening due to accidental collision, thus improving safety. Threaded cooperation allows installation from one side, which is particularly useful for narrow and difficult-to-reach positions, and the internal hexagonal stud and the corresponding threaded hole can also be produced through standardization, thereby ensuring their consistency and interchangeability.
[0011] A backing plate is further provided at the inner end of the side slider facing inward. The adjusting member abuts against the backing plate. Generally, the processing cost of the side slider is higher than that of the backing plate. Therefore, in the present utility model, the backing plate is introduced to prevent the adjusting member from applying excessive pressure and damaging the side slider, increasing the cost. In addition, it can also prevent the unevenness or slight inclination of the surface of the side slider. The backing plate can compensate for these irregularities to ensure that the adjusting member can apply uniform pressure to the side slider.
[0012] An oil storage hole for storing lubricating grease is provided on the outer side surface of the side slider opening inward.
[0013] There are multiple oil storage holes, which are evenly arranged according to the shape of the side slider. The lubricating grease in the oil storage holes can play a lubricating role and reduce the sliding friction resistance of the corresponding components.
[0014] A forklift is provided with the above-mentioned adjustable clearance side slider mechanism.
[0015] The connecting member to be connected is the side plate of the pulley block, and the relative member is the channel steel, and the channel steel is a C-shaped open channel steel. By introducing the side slider mechanism in the present invention to the side plate of the pulley block of the forklift, the swaying amount of the forklift mast can be effectively reduced, the stability of the forklift can be improved, the maintenance cost can be reduced, and the operability of the forklift can be improved. On the basis of reducing the weight of the whole structure, the C-shaped open channel steel can provide good bending strength and torsional stiffness, provide good load-bearing capacity, and increase the stability of the overall structure of the forklift.
[0016] The side slider mechanisms are arranged on the same horizontal line on the side plate of the pulley block and are arranged in at least two groups. Introducing two groups of side slider mechanisms can further improve the stability and safety of the forklift during operation.
[0017] The side slider is embedded in the C-shaped opening of the channel steel, and the gap between the side slider and the web of the channel steel is adjusted by adjusting the adjusting member. When there is relative displacement between the forklift frame and the channel steel and the forces on both sides of the frame are uneven, the frame will swing left and right in the channel steel, increasing the resistance. However, the side slider mechanism in the present invention can adjust the gap between the side slider and the web of the channel steel, so that the side slider abuts against the channel steel, and then the frame can move smoothly in the channel steel.
[0018] The beneficial effects of the present invention are as follows: By independently designing and installing the main roller and the side slider mechanism that can adjust the gap between the adjustable forklift mast and the channel steel, and precisely designing the details of the side slider mechanism, while reducing the swaying amount of the mast and improving the stability of the forklift, the maintenance and replacement costs of the forklift are reduced, and thus the work efficiency is improved.

Specific embodiments
[0027] The technical solutions in the specific embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0028] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0029] Refer to Figure 1 , an adjustable clearance side slider mechanism, including a side slider 1, a side sliding tube 2, an adjusting member 3, and a backing plate 6. The cross-section of the side slider 1 can be a rounded rectangle, a circle, a triangle, etc., and is selected according to the specific use scenario. In this embodiment, the cross-section of the side slider 1 is a rounded rectangle, and its shape is a rounded rectangular block. Correspondingly, the cross-sections of the side sliding tube 2 and the backing plate 6 used in cooperation with it are both rounded rectangles. The sizes of the side slider 1 and the backing plate 6 are slightly smaller than those of the side sliding tube 2. A connecting hole 4 is provided on the component to be connected 8. In this embodiment, the connecting hole 4 is a rectangular stepped hole.
[0030] Refer to Figures 1 to 2When in use, first insert one end of the side sliding tube 2 into the stepped hole, and use welding to achieve mechanical connection between the side sliding tube 2 and the part to be connected 8. Welding can achieve a more solid connection, thereby providing rigidity of the overall structure and reducing structural deformation. In other implementations, other mechanical connection methods can also be used, and are not limited to those that can achieve stable connection. After the side sliding tube 2 is mechanically connected to the part to be connected 8, the pad 6 and the side slider 1 are inserted into the side sliding tube 2 in sequence. The adjustment member 3 is a hexagonal stud with a hexagonal notch 10 at one end. The adjustment member 3 passes through the threaded hole 5 connected to the connecting hole 4 and abuts against the pad 6. Use a tool such as a hexagonal wrench or a hexagonal socket to adjust the hexagonal stud. Through the cooperation between the hexagonal stud and the threaded hole 5, the gap between the side slider 1 and the relative part 9 can be adjusted.
[0031] refer to Figure 4 An oil storage hole 7 is provided on the outer side of the side slider 1 for storing lubricating grease to reduce friction resistance. In this embodiment, the oil storage holes 7 are designed as a nine-square grid on the outer side of the side slider 1. In actual use, the layout can be adjusted according to the specific application scenario of the connected part 8.
[0032] refer to Figures 2 to 3 A forklift is provided with a side slider mechanism with adjustable gap in the utility model. On the forklift, the connecting member 8 is a pulley side plate, and the relative member 9 is a channel steel. The channel steel is a C-shaped open channel steel. The C-shaped open channel steel is usually composed of two parallel flanges (or called side edges) and a web connecting the two flanges to form an open groove structure. The side slider 1 is embedded in the C-shaped opening. By adjusting the adjusting member 3, the gap between the side slider 1 and the web of the channel steel is adjusted. Specifically, after the adjusting member 3 is tightened, the adjusting member 3 applies pressure to the pad 6, thereby reducing the gap between the side slider 1 and the web of the channel steel. When the pulley frame and the channel steel on the forklift are relatively displaced by hydraulics or other means and the forces on both sides of the pulley frame are uneven, the pulley will swing left and right in the channel steel, increasing the resistance of the forklift during operation. The side slider mechanism 13 introduced in the utility model can resist the channel steel, allowing the pulley frame to move smoothly and steadily in the channel steel. The lubricating grease in the oil storage hole 7 of the side slider 2 further reduces the friction resistance during sliding. In this embodiment, at least two sets of side slider mechanisms 13 are introduced on each side of the pulley frame and are arranged on the same horizontal line on the pulley side plate, further improving the stability and safety of the forklift during operation. In addition, refer to Figure 5, which is a composite roller used for gap adjustment in the prior art. The two ends of the central axis of the side roller 12 are stuck on the inner wall of the central hole of the main roller 11. The main roller 11 is responsible for guiding and rolling inside the channel steel, and the side roller 12 is responsible for gap adjustment. Although it has a certain effect in terms of guiding and gap adjustment, since the side roller 12 is embedded in the main roller 11, it causes difficulties in maintenance and replacement, significantly increasing the maintenance cost and time consumption. In the present utility model, by independently designing the main roller 11 and the side slider mechanism 13 on the side plate of the trolley, not only can the gap be adjusted, but also the maintenance and replacement costs during use are significantly reduced, making the operation cost lower and the production efficiency higher.
[0033] The description of the above embodiments is only used to help understand the method and core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the scope of protection of the claims of the present utility model.
