Description

Technical Field

[0001] This invention relates to the technical field of forklift overhead guards, and in particular to an adjustable and adaptive forklift overhead guard. Background Technology

[0002] Forklifts used for handling and loading / unloading various goods are equipped with a top guard as a protective device to prevent the driver from being injured by falling goods when loading or unloading goods at heights. The top guard has a pair of left and right front support pillars spaced apart in the width direction at the front of the forklift body, a pair of left and right rear support pillars spaced apart in the width direction at the rear of the forklift body, and a canopy section spanning between the front and rear support pillars. It is a highly rigid structure designed to protect the driver from injury caused by falling goods.

[0003] For example, Chinese patent document CN223705110U discloses a forklift overhead guard, including multiple pillars, the lower ends of which are detachably mounted on the forklift, and the upper ends of which are connected to the overhead guard. A limiting cavity is formed at the lower end of each pillar, and a positioning block is provided within the limiting cavity. A limiting structure for restricting the movement of the pillar is installed on the positioning block. This utility model has a simple structure. By setting the positioning block and the limiting structure, when disassembling the pillar from the overhead guard, pressing the pressure plate causes the limiting plate to move downwards. The limiting plate can compress the spring, and simultaneously, the limiting plate can cause the locking block to disengage from the slot inside the pillar. When the pillar is unobstructed, it can be pushed forward to disengage from the positioning block for convenient disassembly. During installation and fixing, the pillar can be slidably engaged with the positioning block on the mounting base. Releasing the pressure plate causes the limiting plate and locking block to reset under the push of the spring, and the locking block can engage in the slot, fixing and limiting the movement of the pillar.

[0004] In the aforementioned technologies, when passing through height-restricted areas or underground passage entrances, the overhead guard needs to be removed from the forklift. Since the overhead guard has multiple bolts on its four legs that are fixed to the forklift, all the bolts on the front and rear four legs of the overhead guard need to be removed during the disassembly process. This is time-consuming and labor-intensive, and disassembly tools are also required, making it very inconvenient to adjust the height of the forklift overhead guard. Summary of the Invention

[0005] This application provides an adjustable adaptive forklift overhead guard, which aims to solve the problem in related technologies where it is inconvenient to adjust the height of the forklift overhead guard.

[0006] The adjustable adaptive forklift overhead guard provided in this application adopts the following technical solution: An adjustable adaptive forklift overhead guard includes two front columns and two rear columns. Protective components are mounted on the two front columns and two rear columns to protect the driver on the forklift. Each protective component includes a front rotating plate rotatably connected to the two front columns, a rear rotating plate rotatably connected to the rear columns, a front top plate rotatably connected to the front rotating plate, and a rear top plate rotatably connected to the rear rotating plate. The end of the front top plate away from the front rotating plate is rotatably connected to the rear top plate. A first adjustment component is mounted on the rear columns to drive the rear top plate to rotate. During the rotation of the rear top plate, the front top plate, the rear rotating plate, and the front rotating plate itself will also rotate. During the rotation, the rear rotating plate is also tilted.

[0007] Optionally, the first adjustment assembly includes a first adjustment rod rotatably connected to the side of the rear top plate and a first adjustment block slidably connected to the side of the rear column. The end of the first adjustment rod away from the rear top plate is rotatably connected to the first adjustment block. The rear column has multiple threaded holes that are evenly spaced along the length of the rear column. The first adjustment block has a through hole through which a bolt passes. The bolt on the first adjustment block is used to connect with the threaded hole on the rear column.

[0008] Optionally, each of the two rear uprights is provided with a first support assembly for supporting the two rear uprights. The first support assembly is fixed to the forklift body by bolts, and the two rear uprights are fixed to the forklift body by the first support assembly. Each of the two front uprights is provided with a second support assembly for supporting the two front uprights. The second support assembly is fixed to the forklift body by bolts, and the two front uprights are fixed to the forklift body by the second support assembly.

[0009] Optionally, the first support assembly includes a first support sleeve fixed to the forklift body and a first support spring fixed to the inner wall of the support sleeve. One end of the first support spring is fixed to the rear column. Since there are two rear columns, there are also two first support assemblies. The two first support springs support the two rear columns. The second support assembly includes a second support sleeve fixed to the forklift body and a second support spring fixed to the inner wall of the support sleeve. One end of the second support spring is fixed to the rear column. Since there are two rear columns, there are also two second support assemblies. The two second support springs support the two front columns.

[0010] Optionally, the strength of the second support spring is greater than the strength of the first support spring.

[0011] Optionally, the front rotating plate is provided with a blocking component for blocking objects falling from above the front rotating plate; the blocking component includes a mounting frame rotatably connected to the front rotating plate and a blocking plate slidably connected to the mounting frame, the blocking plate is configured as a folding structure, and a control component is provided on the side of the blocking plate, the control component being used to drive the blocking plate to unfold or retract.

[0012] Optionally, the control assembly includes a control block fixed to the baffle plate and a control screw rotatably connected to the mounting frame. The control screw passes through the control block and is threadedly connected to it, with one end of the control screw extending out of the mounting frame.

[0013] Optionally, each folding position of the blocking plate is fixed with a limit block, and multiple limit blocks are slidably connected to the mounting frame. The driving block is set at the outermost folding position of the blocking plate.

[0014] Optionally, the front rotating plate is provided with a second adjusting component for adjusting the angle of the mounting frame; the second adjusting component includes a second adjusting rod rotatably connected to the side of the mounting frame and a second adjusting block slidably connected to the side of the front rotating plate, with one end of the second adjusting rod away from the mounting frame rotatably connected to the second adjusting block.

[0015] Optionally, the front rotating plate has multiple threaded holes, which are evenly spaced along the length of the front rotating plate. The second adjusting block has a through hole, and a bolt passes through the through hole. The bolt on the second adjusting block is used to connect with the threaded holes on the front rotating plate.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows: During the rotation of the rear top plate, the front top plate, the rear rotating plate, and the front rotating plate will all rotate. During the rotation, the rear rotating plate is also tilted, which makes it easier to adjust the height of the front and rear top plates. Because the strength of the second support spring is greater than that of the first support spring, the first support spring has a larger compression length. At this time, the front and rear top plates will be tilted, which makes it easier for objects on the front and rear top plates to detach. The baffle is designed with a folding structure, similar to the corrugated plate structure. The baffle is made of aluminum alloy. When an object falls from above the front rotating plate, it will land on the baffle, which will then cushion the falling object and further protect the people in the cab.

Detailed Implementation

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with the accompanying drawings. Figure 1-6 This application will be described in further detail.

[0025] This invention discloses an adjustable adaptive forklift overhead guard. (See also...) Figures 1 to 6 An adjustable adaptive forklift overhead guard includes two front uprights 1 and two rear uprights 11. Each of the two rear uprights 11 is provided with a first support assembly 2, which supports the two rear uprights 11. The first support assembly 2 is fixed to the forklift body by bolts 14. The two rear uprights 11 are fixed to the forklift body via the first support assembly 2. Each of the two front uprights 1 is provided with a second support assembly 3, which supports the two front uprights 1 and is fixed to the forklift body by bolts 14. The two front uprights 1 are fixed to the forklift body via the second support assembly 3. The two front uprights 1 are configured with an arc-shaped structure, and the two rear uprights 11 are configured with a vertical state. Protective components 4 are provided on both the two front uprights 1 and the two rear uprights 11 to protect the driver on the forklift body.

[0026] The protective assembly 4 includes a front rotating plate 41 rotatably connected to the two front columns 1, a rear rotating plate 42 rotatably connected to the rear column 11, a front top plate 43 rotatably connected to the front rotating plate 41, and a rear top plate 44 rotatably connected to the rear rotating plate 42. The end of the front top plate 43 away from the front rotating plate 41 is rotatably connected to the rear top plate 44. A first adjustment assembly 5 is provided on the rear column 11. The first adjustment assembly 5 is used to drive the rear top plate 44 to rotate, thereby realizing the adjustment of the angle of the rear top plate 44. During the rotation of the rear top plate 44, the front top plate 43, the rear rotating plate 42, and the front rotating plate 41 will rotate as a whole. During the rotation, the rear rotating plate 42 is also tilted, which makes it easier to adjust the height of the front top plate 43 and the rear top plate 44.

[0027] The front top plate 43 and the rear top plate 44 are provided with clearance grooves 12, which can reduce the weight of the front top plate 43 and the rear top plate 44. The front rotating plate 41 and the rear rotating plate 42 are set as frame structures. A connecting rod 13 is provided between the two front columns 1, and the two ends of the connecting rod 13 are fixedly connected to the two front columns 1 respectively. A connecting rod 13 is also provided between the two rear columns 11, and the two ends of the connecting rod 13 are fixedly connected to the two rear columns 11 respectively. The setting of the connecting rod 13 can improve the strength between the two front columns 1 and the two rear columns 11.

[0028] The first adjustment component 5 includes a first adjustment rod 51 rotatably connected to the side of the rear top plate 44 and a first adjustment block 52 slidably connected to the side of the rear column 11. The end of the first adjustment rod 51 away from the rear top plate 44 is rotatably connected to the first adjustment block 52. In this embodiment, the cross-section of the first adjustment block 52 is set to U-shape and is snapped onto the rear column 11. By moving the first adjustment block 52, the angle of the rear top plate 44 is adjusted under the action of the first adjustment rod 51. While the angle of the rear top plate 44 is adjusted, the front top plate 43, the front rotating plate 41 and the rear rotating plate 42 will be rotated. In this embodiment, during the downward sliding of the first adjusting block 52, the rear top plate 44 will be pulled downward by the action of the first adjusting rod 51. At this time, the front top plate 43 will also move downward, the front rotating plate 41 will rotate towards the rear rotating plate 42, and the rear rotating plate 42 will rotate away from the front rotating plate 41. The rear rotating plate 42 is set at an angle to the plane where the two rear columns 11 are located. At this time, the front top plate 43 and the rear top plate 44 are still on the same plane. During the subsequent use of the forklift body, the front top plate 43 and the rear top plate 44 can still block falling objects, thereby protecting the driver and improving the driver's safety.

[0029] Multiple threaded holes are provided on the rear column 11, and the multiple threaded holes are evenly spaced along the length of the rear column 11. A through hole is provided on the first adjusting block 52, and a bolt 14 is inserted in the through hole. The bolt 14 on the first adjusting block 52 is used to connect with the threaded hole on the rear column 11. When it is necessary to adjust the position of the first adjusting block 52, rotate the bolt 14 to disengage the bolt 14 on the first adjusting block 52 from the rear column 11, and then slide the first adjusting block 52 downward. Adjust the height of the front top plate 43 and the rear top plate 44 to a suitable position so that the bolt 14 on the first adjusting block 52 corresponds to the threaded hole on the rear column 11. Rotate the bolt 14 to connect the bolt 14 on the first adjusting block 52 with the threaded hole on the rear column 11, thereby fixing the position of the first adjusting block 52. After the position of the first adjusting block 52 is fixed, the height of the front top plate 43 and the rear top plate 44 will no longer change. In this embodiment, two first adjustment components 5 are provided, and the two first adjustment components 5 are provided on both sides of the rear top plate 44. By providing two first adjustment components 5, the positions of the front top plate 43 and the rear top plate 44 can be better fixed, thereby improving the strength of the entire top protection frame.

[0030] The first support assembly 2 includes a first support sleeve 21 fixed to the forklift body and a first support spring 22 fixed to the inner wall of the support sleeve. One end of the first support spring 22 is fixed to the rear column 11. Since there are two rear columns 11, in this embodiment, there are also two first support assemblies 2, which support the two rear columns 11 through the two first support springs 22. The second support assembly 3 includes a second support sleeve 31 fixed to the forklift body and a second support spring 32 fixed to the inner wall of the support sleeve. One end of the second support spring 32 is fixed to the rear column 11. Since there are two rear columns 11, in this embodiment, there are also two second support assemblies 3, which support the two front columns 1 through the two second support springs 32.

[0031] In this embodiment, the strength of the second support spring 32 is greater than that of the first support spring 22. After the object falls from above, the object's gravity will push the front top plate 43 and the rear top plate 44 downward. The front top plate 43 and the rear top plate 44 will drive the front rotating plate 41 and the rear rotating plate 42 downward. The front rotating plate 41 and the rear rotating plate 42 will drive the two front columns 1 and the two rear columns 11 downward. The first support spring 22 and the second support spring 32 are both compressed. The first support spring 22 and the second support spring 32 will buffer the falling object. Since the strength of the second support spring 32 is greater than that of the first support spring 22, the first support spring 22 has a larger compression length. At this time, the front top plate 43 and the rear top plate 44 will be tilted, which will facilitate the object on the front top plate 43 and the rear top plate 44 to detach.

[0032] Because the two front pillars 1 are tilted, objects falling from above the front rotating plate 41 will also enter the driver's cab. In this embodiment, a blocking component 6 is provided on the front rotating plate 41 to block objects falling from above the front rotating plate 41 and improve the protection of the driver.

[0033] The blocking assembly 6 includes a mounting frame 61 rotatably connected to the front rotating plate 41 and a blocking plate 62 slidably connected to the mounting frame 61. In this embodiment, the blocking plate 62 is configured as a folding structure, the same as the corrugated plate structure. The material of the blocking plate 62 is aluminum alloy. After an object falls from above the front rotating plate 41, it will fall onto the blocking plate 62, and then the blocking plate 62 will buffer the falling object, further protecting the people in the cab.

[0034] A control component 7 is provided on the side of the baffle 62. The control component 7 is used to drive the baffle 62 to unfold or retract. The greater the degree of folding of the baffle 62, the better the protection against falling objects. Users can adjust the degree of folding of the baffle 62 according to the actual usage scenario. The control component 7 includes a control block 71 fixed on the baffle 62 and a control screw 72 rotatably connected to the mounting frame 61. The control screw 72 passes through the control block 71 and is threadedly connected to it. One end of the control screw 72 extends out of the mounting frame 61. By rotating the control screw 72, the control block 71 slides on the mounting frame 61, and the position of the control block 71 is adjusted. Since the baffle 62 is in a folded state, a limit block 15 is fixed at each folding position of the baffle 62. Multiple limit blocks 15 are slidably connected to the mounting frame 61. The drive block is set at the outermost folding position of the baffle 62. Limiting blocks 15 are provided on both sides of the blocking plate 62. As the driving block moves on the mounting frame 61, the limiting blocks 15 also slide on the mounting frame 61, thereby adjusting the degree of folding of the blocking plate 62.

[0035] A second adjustment component 8 for adjusting the angle of the mounting frame 61 is provided on the front rotating plate 41. The second adjustment component 8 includes a second adjustment rod 81 rotatably connected to the side of the mounting frame 61 and a second adjustment block 82 slidably connected to the side of the front rotating plate 41. The end of the second adjustment rod 81 away from the mounting frame 61 is rotatably connected to the second adjustment block 82. In this embodiment, the cross-section of the second adjustment block 82 is set to U-shape and is snapped onto the front rotating plate 41. When the second adjustment block 82 moves, the angle of the mounting frame 61 is adjusted under the action of the second adjustment rod 81.

[0036] Multiple threaded holes are provided on the front rotating plate 41, and the multiple threaded holes are evenly spaced along the length direction of the front rotating plate 41. A through hole is provided on the second adjusting block 82, and a bolt 14 is inserted in the through hole. The bolt 14 on the second adjusting block 82 is used to connect with the threaded hole on the front rotating plate 41. When it is necessary to adjust the position of the second adjusting block 82, rotate the bolt 14 to disengage the bolt 14 on the second adjusting block 82 from the front rotating plate 41, and then slide the second adjusting block 82 downward. Adjust the mounting frame 61 and the blocking plate 62 on the mounting frame 61 to a suitable position so that the bolt 14 on the second adjusting block 82 corresponds to the threaded hole on the front rotating plate 41. Rotate the bolt 14 to connect the bolt 14 on the second adjusting block 82 with the threaded hole on the front rotating plate 41, thereby fixing the position of the second adjusting block 82. After the position of the second adjusting block 82 is fixed, the mounting frame 61 will not change. In this embodiment, two second adjustment components 8 are provided, and the two second adjustment components 8 are provided on both sides of the rear top plate 44. By providing two second adjustment components 8, the positions of the front top plate 43 and the rear top plate 44 can be better fixed, thereby improving the strength of the entire top protection frame.

[0037] The implementation principle of an adjustable adaptive forklift overhead guard in this application embodiment is as follows: When the height of the front overhead plate 43 and the rear overhead plate 44 needs to be adjusted, the bolt 14 is rotated to disengage the bolt 14 on the first adjusting block 52 from the rear column 11. Through the movement of the first adjusting block 52, the height of the front overhead plate 43 and the rear overhead plate 44 is adjusted to a suitable position, so that the bolt 14 on the first adjusting block 52 corresponds to the threaded hole on the rear column 11. During the downward movement of the first adjusting block 52, the angle of the rear overhead plate 44 is adjusted under the action of the first adjusting rod 51. At the same time as the angle of the rear overhead plate 44 is adjusted, the front overhead plate 43, the front rotating plate 41, and the rear rotating plate 42 will rotate. During the downward sliding of the first adjusting block 52, the first adjusting rod 51 will pull the rear top plate 44 downward. At this time, the front top plate 43 will also move downward. The front rotating plate 41 will rotate towards the rear rotating plate 42, and the rear rotating plate 42 will rotate away from the front rotating plate 41. The rear rotating plate 42 is set at an angle to the plane where the two rear columns 11 are located. At this time, the front top plate 43 and the rear top plate 44 are still on the same plane. During the subsequent use of the forklift body, the front top plate 43 and the rear top plate 44 can still block falling objects, thereby protecting the driver and improving the driver's safety.
