Description

Technical Field

[0001] The utility model relates to a forklift, in particular to a forklift with a frame component installed on the fork teeth. Background Art

[0002] In the production of chemical products, forklifts are frequently used to transport goods of different sizes. For example, in polyurethane product manufacturers, materials of different states, specifications, and sizes are used, such as liquid materials such as polyols and prepolymers, solid goods such as powders and thermoplastic polyurethane (TPU) plastic particle products, and hardware accessories, packaging consumables, etc.; and the specifications and sizes of goods are also varied. For example, the barrel for holding materials may be a cylinder or a square barrel, or individually packaged accessories. For practical operation and safety needs, production personnel need to operate forklifts with different tine sizes. When switching, operators usually need to make new estimates and judgments, which is inconvenient and prone to accidents. For example, if the tine is too long, the goods may be broken or cannot be operated normally, especially when transporting some non-standard goods. Therefore, in actual operation, a forklift with tine that can flexibly adjust the length of use is required.

[0003] Chinese patent CN 218114942U discloses a forklift, which can accurately control the fork-carrying length of the fork tine and has the following structure: the forklift includes a body and a limit assembly; the body is equipped with fork tine; the limit assembly includes a blocking element and a first wall body and a second wall body respectively connected to opposite ends of the blocking element, the blocking element is located above the fork tine, the first wall body and the second wall body are respectively located on opposite sides of the width direction of the fork tine, and the limit assembly can move relative to the fork tine along the length direction of the fork tine; a first abutting element is arranged on the first wall body, the free end of the first abutting element is located between the first wall body and the second wall body, and the distance between the free end of the first abutting element and the second wall body is adjustable so that the free end of the first abutting element can abut the fork tine.

[0004] Chinese patent CN 204111255 U discloses a forklift auxiliary device, which includes an isolation frame and a flat sleeve. The isolation frame is arranged between the forklift arm and the forked object; it is located on the fork tine near one end of the forklift arm; and the fork tine tip is covered with a flat sleeve, and the edge of the flat sleeve is an arc-shaped transition. The isolation frame of the utility model is placed on the fork tine of the forklift, that is, it is spaced between the forklift arm and the forked object, so that when the forklift forks the forked object, the fork tine no longer protrudes outside the forked object, and when the forklift forks the forked object, the fork tine will not contact the previous forked object in the same row, and will not damage it; the two flat sleeves are covered on the tooth tips of the two fork tine to play a better protective role. When using the utility model, even forklift operators who are not skilled in operation will not damage the roll paper when the roll paper is put into storage.

[0013] The utility model relates to a forklift, which is provided with fork teeth. A movable frame component is connected to the fork teeth, and the position of the frame component on the fork teeth can be adjusted and fixed.

[0014] The utility model can freely and flexibly adjust the actual use length of the fork tines by adjusting the position of the frame component on the fork tines and fixing it at a desired position when in the working position. Theoretically, the frame component can have any shape. Preferably, the frame component is flat, and its two ends are preferably hollow in the longitudinal direction, that is, in the direction parallel to the fork tines, and the fork tines preferably pass through the hollow part and fit with the frame component. Preferably, the upper surface of the frame component is as close as possible to the upper surface of the fork tines, so that the material transported by the forklift can be easily moved from the part of the fork tines without the frame component to the frame component with the fork tines with the frame component. In addition, the frame component can play a role of stable support, and can support larger and heavier goods, which is convenient for loading and unloading and transportation.

[0015] In some preferred embodiments, the frame member is a square-shaped plate having a longitudinal portion in the length direction of the fork tines and a transverse portion in a direction perpendicular to the length direction of the fork tines.

[0016] Preferably, the frame member is a square-shaped plate, which can save material compared with a rectangular plate while still maintaining sufficient mechanical strength and a stable supporting effect on the transported goods.

[0017] The hollow part of the U-shaped plate can be square, rectangular, circular or irregular in shape, preferably rectangular.

[0018] Preferably, the longitudinal portion of the U-shaped plate fits with the fork tine in a nested manner, that is, the longitudinal portion is an open hollow shape, and the fork tine is inserted into the open hollow portion of the longitudinal portion. The U-shaped plate and the fork tine are tightly connected together, and the connection is more firm and stable.

[0019] The frame member and the fork tines may be connected in any conventional manner in the art. For example, the frame member and the fork tines may be provided with a plurality of corresponding spaced limiting holes or limiting grooves, and after the relative positions of the frame member and the fork tines are determined, the two may be fixed by screws or the like.

[0020] Preferably, in the case of the U-shaped plate, there are recesses on the fork tines, there are recesses on the inner side or the outer side of the longitudinal portion of the U-shaped plate, and the U-shaped plate and the two fork tines are fixed together by a fixing element.

[0021] In some preferred embodiments, the longitudinal portion of the U-shaped plate is provided with a recess on the inner side or the outer side, and the fork tine has a corresponding recess, through which the U-shaped plate and the fork tine are fixed by fixing screws or positioning pins. Preferably, the fixing element is on the inner side of the longitudinal portion of the U-shaped plate, so that the fixing element is not easily knocked off or damaged.

[0022] Herein, the recess may have any shape, and preferably it may be a hole, a groove, a slit, etc. The fixing element may be a fixing screw, a positioning pin, etc.

[0023] Herein, when the recess is a hole, there is no restriction on the number, position, spacing and shape of the holes, as long as it can play the above-mentioned fixed connection role and facilitate the positioning of the frame parts. When the recess is a groove or a slit, the recess may be marked with scales to facilitate the positioning of the frame parts.

[0024] Furthermore, the frame parts and the fork tines can also be fixed together by means of a clamping device. In the case of a square-shaped plate, the clamping device can serve as a transverse part of the square-shaped plate.

[0025] The present invention is not limited to the above connection method, and all methods that can connect and fix the frame parts and the fork teeth together can be used in the present invention.

[0026] In some preferred embodiments, the frame member can be adjusted in size in its transverse direction, i.e., in a direction perpendicular to the length of the fork tines, so that the frame member can be mounted on fork tines of any size, which is particularly applicable when the width of the fork tines is adjustable. Moreover, the transverse dimension of the frame member can be similar to the distance between the two fork tines, or can be longer than the distance between the two fork tines, so as to more conveniently carry and support long goods placed transversely on the frame member.

[0027] In some further preferred embodiments, the frame member is a U-shaped plate, and the total length of the transverse portion of the U-shaped plate is adjustable. The length of the transverse portion of the U-shaped plate can be adjusted by a telescopic device conventionally used in the art. The frame member of the utility model is generally applicable. Since not only the position of the frame member in the length direction of the fork tine can be adjusted, but also the size of the transverse portion of the frame member, i.e., the portion in the direction perpendicular to the length direction of the fork tine, can be adjusted, it is suitable for installation on fork tine with any size.

[0028] Preferably, the transverse portion of the U-shaped plate includes a first portion and a second portion, the first portion and the second portion are fixed together by fixing screws or locating pins and their corresponding recesses, and the total length of the first portion and the second portion can be adjusted by adjusting the position of the fixing screws or locating pins.

[0029] In some further embodiments, the first portion of the transverse portion of the U-shaped plate is hollow and wider than the second portion, and the end of the second portion extends into the hollow space of the first portion.

[0030] In addition, the first part and the second part of the transverse part of the U-shaped plate can also be fixed together in a superimposed manner by a fixing element. By adjusting the position of the fixing element and the corresponding recess, the total length of the transverse part of the U-shaped plate can be adjusted.

[0031] In some preferred embodiments, the width of the transverse portion of the Chinese-shaped plate is 1 cm to 15 cm, preferably 2 cm to 12 cm. Here, the width of the transverse portion of the Chinese-shaped plate does not refer to the width of the Chinese-shaped plate as a whole, but the width of a frame in the transverse direction of the Chinese-shaped plate. It should be easily understood that there are two frames in the transverse direction of the Chinese-shaped plate. In other words, the transverse portion of the Chinese-shaped plate is composed of two frames in the transverse direction, and the width of each of the two frames is preferably 1 cm to 15 cm, more preferably 2 cm to 12 cm.

[0032] Within the above-mentioned ratio range, the U-shaped plate can achieve a better balance between material saving and sufficient mechanical strength and supporting stability.

[0033] In other embodiments, the frame member is a rectangular plate, and the rectangular plate and the fork teeth are fitted together. Relative to the square plate, the rectangular plate is more stable when supporting goods, but it has the disadvantages of being difficult to adjust the width and requiring more materials.

[0034] The rectangular plate and the fork tines can be fixed together using the aforementioned connection method.

[0035] In some more preferred embodiments, the ratio of the dimension of the frame member in a direction parallel to the tines to the length of the tines is in the range of 1:2-4.

[0036] If the ratio is too small, the cargo may be unstable on the fork tines when the forklift is transporting the cargo. If the ratio is too large, the actual use length of the fork tines and the adjustment range of the actual use length of the fork tines may be improperly limited.

[0037] It should be understood that those skilled in the art may also make further modifications based on the present invention. For example, the transverse portion of a frame component such as a U-shaped plate or a rectangular plate may have continuous or discontinuous recesses, such as continuous slits or grooves or discontinuous holes, etc., and a thin plate or a metal strip may be inserted into the recess to play a blocking role, so that the actual use length of the fork tines can be better adjusted during actual use.

[0038] The forklift provided by the utility model can freely adjust the actual use length of the fork tines, which can avoid the risk of breaking the goods or not being able to operate normally due to the fork tines being too long when transporting some non-standard goods, especially small goods. In addition, the frame parts on the fork tines can also serve as a pallet, eliminating the need for the pallet, which is very convenient.

[0039] The forklift body provided by the utility model can be an existing commercial product, and the frame parts thereof are manufactured by common mechanical parts processing methods, such as casting, machining, and, if necessary, welding and other technologies to form the required frame parts. The material can be metal and hard plastic, preferably steel.

[0040] When in use, the frame component of the utility model is sleeved into the fork tine of a forklift, moved to a desired position according to actual needs, and fixed on the fork tine, and then the forklift can be used.

[0041] The forklift provided by the utility model is particularly suitable for use in the chemical industry, especially for the loading, unloading and transportation of chemical products. Chemical products, especially liquid materials, must be prevented from dumping and spilling during transportation to avoid environmental pollution or personal injury. Liquid materials are generally transported in barrels, which are generally cylindrical or cubic. The barrels involved in chemical production are generally relatively large, such as large ton barrels (for example, 1 ton capacity), medium-sized ones are generally 200kg cylinders (diameter 60-80cm), and small ones are such as 60kg barrels (diameter 30-50cm). Therefore, during transportation, the bottom of the transport vehicle needs to be able to stably support sufficient supporting surfaces for these barrels. As mentioned above, the frame component provided by the utility model can solve this problem well.

[0042] Now, some specific implementation methods of the utility model are described in conjunction with the accompanying drawings.

[0043] Figure 1 This is a schematic diagram of a preferred embodiment of the utility model, wherein the forklift as a whole is represented by 100, the frame component is a U-shaped plate, represented by 1, the fork tine is represented by 2, and a plurality of limiting holes 3 are provided on the inner side of the fork tine. The inner side of the longitudinal part of the U-shaped plate has a hole for the screw to pass through, and the fixing screw 4 passes through the hole and enters the limiting hole 3. After tightening, the U-shaped plate and the two fork tines can be fixed together. Figure 1 The main parts and frame parts of the forklift are made of steel.

[0044] Figure 2 This is a schematic diagram of a further preferred embodiment of the utility model, wherein the frame component is a U-shaped plate, and the figure is a schematic diagram of a top view of the U-shaped plate when it is placed horizontally. Figure 2In the figure, the horizontal part of the U-shaped plate can be divided into two parts, the left part is the first part, indicated by 5, and the right part is the second part, indicated by 6. The first part 5 is wider than the second part 6, and the first part 5 and the second part 6 are fixed together by a positioning screw or a positioning pin 7 and a corresponding recess. The total length of the first part and the second part, that is, the total length of the horizontal part of the U-shaped plate, is adjusted by adjusting the position of the recess corresponding to the screw or the positioning pin, thereby achieving the purpose of adjusting the total length of the horizontal part of the U-shaped plate.
