Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to an anti-seismic and noise-reducing internal combustion counterbalanced forklift. Background Art

[0002] During the operation of a forklift, due to factors such as uneven ground, changes in the weight of goods, and operation methods, large vibrations and noises will be generated. These vibrations and noises will not only affect the comfort and health of the driver, but may also cause interference to the surrounding environment. Therefore, for an internal combustion counterbalanced forklift, improving the shock absorption effect and reducing the noise level are crucial.

[0003] The existing patent (publication number: CN213060076U) proposed an internal combustion counterbalanced forklift, including a forklift, fork teeth, a cockpit, a first support rod, a second support rod, a baffle, a pluggable storage counterweight box structure, a pluggable rotating horizontal detection frame structure, a retractable adsorption shielding frame structure, a counterweight block, a lifting ring, a seat, and a plug-in box.

[0004] The setting of the fixing plate, the first connecting rod, the locking nut, the plug-in box, the forklift, and the counterweight block of the utility model is beneficial to changing the weight of the forklift itself by disassembling the counterweight block during the working process, which is convenient for transporting or loading and unloading goods of different weights; the setting of the L-shaped connecting rod, the plug-in slot, the first rotating rod, the balance rod, the forklift, and the first support rod is beneficial to observing the balance degree of the forklift by observing the perpendicularity of the balance rod and the L-shaped connecting rod during the working process, and preventing the forklift from tilting forward during the process of lifting goods.

[0005] However, in actual use, there are still the following deficiencies. For example, the existing internal combustion counterbalanced forklift cannot meet the anti-seismic and noise-reducing effects. If the vibration is too large during the handling process of the forklift, it may cause the goods to collide, fall, or deform. Especially when handling precision instruments or fragile items, this risk is particularly prominent. Long-term exposure to a high-noise environment may cause problems such as hearing damage and increased psychological pressure for the operator. Excessive vibration may also cause physical discomfort for the operator, such as occupational diseases like low back pain and wrist pain. Therefore, the utility model proposes an anti-seismic and noise-reducing internal combustion counterbalanced forklift to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an anti-seismic and noise-reducing internal combustion counterbalanced forklift.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: an anti-seismic and noise-reducing internal combustion counterbalanced forklift, including a forklift, tires are arranged on the forklift, anti-seismic and noise-reducing components are arranged on the tires, a fork arm is arranged on the forklift, and a seat is arranged on the forklift;

[0010] The beneficial effect of adopting the above further scheme is that since the first fixing plate is fixedly connected to the bottom of the forklift, the entire anti-seismic and noise-reducing component can be fixedly connected to the bottom of the forklift. Since the second fixing plate is fixedly connected to the tire, the entire anti-seismic and noise-reducing component can be fixedly connected to the tire.

[0011] As a preferred embodiment, a limiting rod is fixedly connected to the slider, the limiting rod is slidably connected to the limiting seat, a limiting block is fixedly connected to the limiting rod, a first telescopic spring is arranged on the limiting rod, one end of the first telescopic spring is fixedly connected to the limiting seat, and the other end of the first telescopic spring is fixedly connected to the limiting block.

[0014] The beneficial effect of adopting the above further scheme is that when the forklift encounters a bumpy road section, the fixing column will slide up and down within the third hollow tube, and the fixing column drives the third limiting column to rotate.

[0015] As a preferred embodiment, a second telescopic spring is provided on the third limiting post, a second hollow tube is slidably connected to the third limiting post, one end of the second telescopic spring is fixedly connected to the third limiting post, and the other end of the second telescopic spring is fixedly connected to the second hollow tube. A second fixing seat is rotatably connected to the second hollow tube, and the second fixing seat is fixedly connected to the support seat.

[0016] The beneficial effect of adopting the above further solution is that through the cooperation of the third limiting post, the second telescopic spring and the second hollow tube, the third limiting post slides in the second hollow tube, and the second telescopic spring and the third telescopic spring can exert an elastic force on the fixed post.

[0017] As a preferred embodiment, a fourth limiting post is fixedly connected to the fixed post, a third telescopic spring is provided on the fourth limiting post, a third hollow tube is slidably connected to the fourth limiting post, and the third hollow tube is fixedly connected to the bottom of the support seat.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] As Figures 1 - 3 shown, this embodiment provides a technical solution: an anti-seismic and noise-reducing internal combustion counterbalanced forklift, including a forklift 1, a tire 2 is arranged on the forklift 1, an anti-seismic and noise-reducing component 3 is arranged on the tire 2, a fork arm 4 is arranged on the forklift 1, and a seat 5 is arranged on the forklift 1;

[0033] As Figures 2 - 3As shown in the figure, the earthquake-resistant and noise-reducing component 3 includes a first fixing plate 31. A first limiting column 32 is fixedly connected to the first fixing plate 31. A first hollow tube 33 is slidably connected to the first limiting column 32. A fixing block 34 is fixedly connected to the first hollow tube 33. A limiting seat 35 is fixedly connected to the fixing block 34. A first rotating rod 36 is rotatably connected to the first fixing plate 31. A slider 37 is rotatably connected to the first rotating rod 36. The slider 37 is slidably connected within the limiting seat 35. A second rotating rod 311 is rotatably connected to the slider 37. A second limiting column 312 is slidably connected within the first hollow tube 33. A second fixing plate 313 is fixedly connected to the second limiting column 312. When an operator is driving the forklift 1, factors such as uneven ground, changes in the weight of the goods, and operation methods may be encountered, all of which may affect the stability and safety of the forklift 1. The first fixing plate 31 and the second fixing plate 313 are connected together through the first hollow tube 33. The first limiting column 32 and the second limiting column 312 can slide within the first hollow tube 33. When the forklift 1 encounters situations such as uneven ground or changes in the weight of the goods, the first fixing plate 31 and the second fixing plate 313 will move accordingly, driving the first rotating rod 36 and the second rotating rod 311 to rotate. Since the first rotating rod 36 and the second rotating rod 311 are connected to the slider 37, the slider 37 will slide within the limiting seat 35, playing a role in limiting the movement of the first fixing plate 31 and the second fixing plate 313, effectively reducing the vibration and noise during the operation of the forklift 1, improving the stability and safety of the forklift 1. At the same time, since the first fixing plate 31 and the second fixing plate 313 can freely slide within the first hollow tube 33, the operation of the forklift 1 is also more flexible and convenient, thus solving the technical problem of earthquake resistance and noise reduction for the internal combustion counterbalanced forklift 1.

[0034] In the above solution, there is also a problem that when encountering factors such as uneven ground, changes in the weight of the goods, and operation methods, it cannot meet the driving comfort of the driver. For example Figures 2 - 3As shown in the figure: The first fixed plate 31 is fixedly connected to the bottom of the forklift 1, and the second fixed plate 313 is fixedly connected to the tire 2. Since the first fixed plate 31 is fixedly connected to the bottom of the forklift 1, the overall anti-seismic and noise-reducing component 3 can be fixedly connected to the bottom of the forklift 1. Since the second fixed plate 313 is fixedly connected to the tire 2, the overall anti-seismic and noise-reducing component 3 can be fixedly connected to the tire 2. A limiting rod 38 is fixedly connected to the slider 37. The limiting rod 38 is slidably connected to the limiting seat 35. A limiting block 39 is fixedly connected to the limiting rod 38. A first telescopic spring 310 is arranged on the limiting rod 38. One end of the first telescopic spring 310 is fixedly connected to the limiting seat 35, and the other end of the first telescopic spring 310 is fixedly connected to the limiting block 39. Since the limiting rod 38 is fixedly connected to the slider 37, the limiting rod 38 is slidably connected to the limiting seat 35, the limiting block 39 is fixedly connected to the limiting rod 38, and the first telescopic spring 310 is arranged on the limiting rod 38, when the slider 37 moves in the limiting seat 35, it will drive the limiting rod 38 to slide on the limiting seat 35 and can pull the first telescopic spring 310. By fixedly connecting one end of the first telescopic spring 310 to the limiting seat 35 and the other end of the first telescopic spring 310 to the limiting block 39, the first telescopic spring 310 can provide an elastic force to the slider 37, further enhancing the anti-seismic effect;

[0035] As Figures 4 - 5As shown in the figure, a shock absorption component 6 is provided on the forklift 1. The shock absorption component 6 includes a support base 61 which is fixedly connected to the forklift 1. A base 62 is slidably connected to the support base 61. A seat 5 is fixedly connected to the base 62. A fixed column 63 is fixedly connected to the base 62. A first fixed seat 64 is fixedly connected to the fixed column 63. A third limit column 65 is rotatably connected to the first fixed seat 64. When the forklift 1 encounters a bumpy road section, the fixed column 63 will slide up and down in the third hollow tube 611. The fixed column 63 drives the third limit column 65 to rotate. A second telescopic spring 66 is provided on the third limit column 65. A second hollow tube 67 is slidably connected to the third limit column 65. One end of the second telescopic spring 66 is fixedly connected to the third limit column 65, and the other end of the second telescopic spring 66 is fixedly connected to the second hollow tube 67. A second fixed seat 68 is rotatably connected to the second hollow tube 67, and the second fixed seat 68 is fixedly connected to the support base 61. Through the cooperation of the third limit column 65, the second telescopic spring 66 and the second hollow tube 67, the third limit column 65 slides in the second hollow tube 67, and the second telescopic spring 66 and the third telescopic spring 69 can exert an elastic force on the fixed column 63. A fourth limit column 610 is fixedly connected to the fixed column 63. A third telescopic spring 69 is provided on the fourth limit column 610. A third hollow tube 611 is slidably connected to the fourth limit column 610, and the third hollow tube 611 is fixedly connected to the bottom of the support base 61, which can slow down the vibration generated by the bumps and prevent the long-term bumpy vibration from affecting the driver's work efficiency and safety.

[0036] Working principle:

[0037] As Figures 1 - 5As shown, when an operator is driving the forklift 1, factors such as uneven ground, changes in the weight of the goods, and the operation method may be encountered, all of which may affect the stability and safety of the forklift 1. The first fixing plate 31 and the second fixing plate 313 are connected together by the first hollow tube 33. The first limiting column 32 and the second limiting column 312 can slide within the first hollow tube 33. When the forklift 1 encounters situations such as uneven ground or changes in the weight of the goods, the first fixing plate 31 and the second fixing plate 313 will move accordingly, driving the first rotating rod 36 and the second rotating rod 311 to rotate. Since the first rotating rod 36 and the second rotating rod 311 are connected to the slider 37, the slider 37 will slide within the limiting seat 35, playing a limiting role in the movement of the first fixing plate 31 and the second fixing plate 313, which can effectively reduce the vibration and noise during the operation of the forklift 1, improve the stability and safety of the forklift 1. At the same time, since the first fixing plate 31 and the second fixing plate 313 can freely slide within the first hollow tube 33, the operation of the forklift 1 is also more flexible and convenient. Subsequently, the fixing column 63 will slide up and down within the third hollow tube 611, and the fixing column 63 drives the third limiting column 65 to rotate. Through the cooperation of the provided third limiting column 65, the second telescopic spring 66, and the second hollow tube 67, the third limiting column 65 slides within the second hollow tube 67. The second telescopic spring 66 and the third telescopic spring 69 can exert an elastic force on the fixing column 63, which can slow down the vibration generated by the bumps and prevent the long-term bump vibration from affecting the work efficiency and safety of the driver.

[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
