Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fork truck, specifically a half linkage's inching brake device. BACKGROUND

[0002] The fork truck is a general hoisting and transporting machine, which is mainly used in stations, warehouses, ports and factories to carry out loading and unloading, stacking and short-distance transporting operations, etc. In the process of carrying and loading and unloading goods, the driver needs to frequently use the brake device of the fork truck to complete the work. The brake device of the fork truck includes an inching and braking system. Therefore, the reliability of the braking and inching of the fork truck and the height of the pedal determine the comfort level of the operation of the driver of the fork truck.

[0003] The common inching and braking pedal system adopts a full linkage mode. The limit of the braking pedal is realized by the limiting plate of the inching assembly. When the driver of the fork truck steps on the inching pedal, the inching assembly pushes the limiting plate through the limiting bolt to drive the braking assembly to move together, thereby realizing the effect of simultaneous linkage of inching and braking. However, the inching and braking pedal mechanism adopting the full linkage mode has the following disadvantages:

[0004] 1) The inching assembly and the braking assembly are simultaneously linked, which causes the brake to intervene before the inching valve is completely disconnected, thereby causing the inching effect of the fork truck to be not obvious;

[0005] 2) In order to make the inching effect obvious, a larger air travel needs to be provided for the braking assembly, which causes the air travel of the braking pedal to be too large when the braking pedal is stepped on alone, thereby reducing the reliability of the braking;

[0006] 3) In order to enable the braking pedal to have sufficient rotating distance in the air travel, the distance from the braking assembly and the inching assembly to the bottom plate of the fork truck needs to be further increased, which causes the height of the pedal bottom plate to be too large, thereby causing the driver of the fork truck to be not comfortable in operation (the national standard requires that the braking assembly and the inching assembly need to be kept at the same height). CONTENT OF THE UTILITY MODEL

[0007] To achieve the above-mentioned purpose, the utility model provides the technical scheme as follows:

[0008] A half-linkage inching and braking device, which comprises a support assembly, an inching sleeve and a braking sleeve mounted on the outer side of the support assembly, a inching assembly fixed on the outer side of the inching sleeve, a braking assembly fixed on the outer side of the braking sleeve, a delay space provided between the inching assembly and the braking assembly, and the braking assembly located in the rotating direction of the inching assembly, so that the inching assembly drives the braking assembly after a delay after being started.

[0009] Preferably, the braking assembly includes a brake plate, which is fixedly connected to the brake sleeve; the micro-motion assembly includes a micro-motion plate, which is fixedly connected to the micro-motion sleeve, and a delay space is provided between the micro-motion plate and the brake plate. The brake plate is arranged in the rotation direction of the micro-motion plate so that the brake plate is driven after the micro-motion plate rotates with a delay.

[0010] Preferably, the braking assembly includes a brake plate, which is fixedly connected to the brake sleeve; the micro-motion assembly includes a micro-motion plate, which is fixedly connected to the micro-motion sleeve, and the projection of the micro-motion plate in the vertical direction falls on the outer side of the brake plate. The micro-motion plate and the brake plate maintain a distance, so that the brake plate is driven after the micro-motion plate rotates with a delay.

[0011] Preferably, a limiting bolt is provided through the end of the micro-motion plate away from the micro-motion sleeve, and the limiting bolt is adjusted along the length direction to maintain the distance between it and the brake plate.

[0012] Preferably, the brake plate is fixedly connected to a drive plate, one end of the drive plate is fixedly connected to the brake sleeve, and the other end is movably connected to a brake valve.

[0013] Preferably, the micro-motion sleeve is fixedly connected to a zipper ring, the zipper ring is connected to a micro-motion pull wire, and the end of the micro-motion pull wire away from the zipper ring is connected to a rocker arm bracket assembly.

[0014] Preferably, the micro-motion sleeve is connected to a micro-motion pedal assembly, the micro-motion pedal assembly includes a micro-motion pedal and a micro-motion pedal wall, and the micro-motion pedal and the micro-motion sleeve are respectively fixed to both ends of the micro-motion pedal wall.

[0015] Preferably, the brake sleeve is connected to a brake pedal assembly, the brake pedal assembly including a brake pedal and a brake pedal wall, and the brake pedal and brake sleeve are respectively fixed at both ends of the brake pedal wall.

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This invention provides a delay space between the micro-motion component and the braking component, with the braking component positioned in the rotational direction of the micro-motion component. This allows the micro-motion component to drive the braking component after a delay following its activation. By providing this delay space between the micro-motion component and the braking component, the braking only begins after the forklift has made a micro-motion. This solves the problem in the prior art where the micro-motion assembly and braking assembly operate simultaneously, causing the braking to engage before the micro-motion valve is fully disengaged, resulting in an insignificant micro-motion effect. The semi-coupling method makes the micro-motion effect more pronounced and reduces the idle travel of the braking assembly, improving braking reliability. It also further reduces the distance between the braking assembly and the micro-motion assembly and the forklift floor, improving the forklift driver's comfort. Meanwhile, the limiting bolt is provided on the brake pedal assembly to adjust the distance between the limiting bolt and the brake pedal assembly. The forklift driver can adjust the distance between the limiting bolt and the brake pedal assembly according to actual needs, thereby changing the micro-motion and braking semi-clutch effect. This allows the forklift driver to adjust the micro-motion and braking according to the actual needs on site, making it easier to control the forklift. Attached Figure Description

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] See attached document Figures 1-3 This embodiment of a semi-interlocking micro-motion braking device includes a bracket assembly 100 fastened to a forklift, a micro-motion assembly 200 and a braking assembly 300 mounted on the outer surface of the bracket assembly 100. The micro-motion assembly 200 includes a micro-motion sleeve 220, which is rotatably connected to the outer surface of the bracket assembly 100. A micro-motion component 240 is fixedly connected to the outer surface of the micro-motion sleeve 220. The braking assembly includes a braking sleeve 320, which is rotatably connected to the outer surface of the bracket assembly 100. A braking component 310 is fixedly connected to the outer surface of the braking sleeve 320. A delay space is provided between the micro-motion component 240 and the braking component 310, and the braking component 310 is located in the rotation direction of the micro-motion component 240, so that the braking component 310 is driven by the micro-motion component 240 after a delay.

[0029] When the forklift driver presses the micro-motion assembly 200, the micro-motion sleeve 220 drives the micro-motion component 240 to rotate. After rotating for a period of time, the micro-motion component 240 contacts the braking component 310, which in turn drives the braking component 310 to rotate. The rotation of the braking component 310 then drives the brake sleeve 320 to rotate, thus braking the forklift. By providing a delay space between the micro-motion component 240 and the braking component 310, and by positioning the braking component 310 in the rotation direction of the micro-motion component 240, the braking assembly 300 begins braking only after the micro-motion assembly 200 has started braking for a certain period. This improves the micro-motion effect of the forklift, reduces the idle travel of the braking assembly 300, increases braking reliability, and reduces the distance between the micro-motion assembly 200 and the braking assembly 300 and the forklift floor, improving the driver's comfort.

[0030] In another embodiment, such as Figure 2As shown, the braking assembly 310 includes a brake plate 312, which is fixedly connected to the brake sleeve 320; the micro-motion assembly 240 includes a micro-motion plate 241, which is fixedly connected to the micro-motion sleeve 220. A delay space is provided between the micro-motion plate 241 and the brake plate 312, and the brake plate 312 is arranged in the rotation direction of the micro-motion plate 241 so that the brake plate 312 is driven after the micro-motion plate 241 rotates.

[0031] When the forklift driver presses the micro-motion assembly 200, the micro-motion sleeve 220 drives the micro-motion plate 241 to rotate. After a period of time, the micro-motion plate 241, along with the brake plate 312, drives the brake plate 312 to rotate. The rotation of the brake plate 312 then drives the brake sleeve 320 to rotate, thus braking the forklift. A delay space is provided between the micro-motion plate 241 and the brake plate 312, allowing the brake assembly 300 to begin braking only after the micro-motion assembly 200 has started braking for a certain period. This improves the micro-motion effect of the forklift, reduces the idle travel of the brake assembly 300, increases braking reliability, and reduces the distance between the micro-motion assembly 200 and the brake assembly 300 and the forklift floor, improving the driver's comfort.

[0032] In another embodiment, such as Figure 2 As shown, a limiting bolt 242 passes through the end of the micro-motion plate 241 away from the micro-motion sleeve 220. The distance between the limiting bolt 242 and the brake plate 312 is adjusted along the length direction. When it is necessary to change the time when the micro-motion plate 241 rotates and then drives the brake plate 312, the distance between the limiting bolt 242 and the brake plate 312 can be adjusted by rotating the limiting bolt 242, thereby increasing or decreasing the time when the micro-motion plate 241 rotates and then drives the brake plate 312 to rotate.

[0033] In another embodiment, such as Figure 2 The brake plate 312 is fixedly connected to a drive plate 311. The lower side of the drive plate 311 is fixedly connected to the brake plate 312. One end of the drive plate 311 is fixedly connected to the brake sleeve 320, and the other end is movably connected to a brake valve 340. When the micro-motion plate 241 rotates and then drives the brake plate 312 to rotate, the brake plate 312 drives the brake valve 340 to deliver brake fluid to the drive axle through the left and right brake lines, thereby achieving braking.

[0034] In another embodiment, such as Figure 1As shown, the micro-motion assembly 200 also includes a micro-motion pedal assembly 210, which includes a micro-motion pedal and a micro-motion pedal wall. The micro-motion pedal and a micro-motion sleeve 220 are respectively fixed to both ends of the micro-motion pedal wall. When the forklift driver needs to apply micro-braking, he presses the micro-motion pedal, which drives the micro-motion sleeve 220 to rotate via the micro-motion pedal arm, thereby achieving micro-braking.

[0035] In another embodiment, such as Figure 1 As shown, the micro-motion sleeve 220 is fixedly connected to a zipper hook 230, and the zipper hook 230 is connected to a micro-motion cable 250. The end of the micro-motion cable 250 away from the zipper hook 230 is connected to a rocker arm bracket assembly 400. When the forklift driver presses the micro-motion pedal, causing the micro-motion sleeve 220 to rotate, the micro-motion sleeve 220 drives the micro-motion cable 250 to pull the rocker arm bracket assembly 400, thereby achieving micro-motion braking.

[0036] In another embodiment, such as Figure 2 As shown, the braking assembly 300 also includes a brake pedal assembly 330, which includes a brake pedal and a brake pedal wall. The brake pedal and brake sleeve 320 are respectively fixed to both ends of the brake pedal wall. When the forklift driver needs to brake, he presses the brake pedal, and the brake pedal drives the brake sleeve 320 to rotate through the brake pedal arm, thereby achieving braking.

[0037] Specifically, the brake sleeve 320 is fitted with a brake return torsion spring 350 to enable the brake assembly 300 to return to its original position quickly.

[0038] In another embodiment, such as Figure 3 As shown, the bracket assembly 100 is provided with a connecting plate 110, and a transverse plate is fixedly connected to the connecting plate 110 in the horizontal direction. A limiting member 120 is provided through the transverse plate, and a limiting plate 130 for limiting the brake pedal wall is connected to one end of the limiting member 120 in the length direction. The limiting plate 130 limits the brake pedal wall, preventing the brake return torsion spring 350 from pulling up the height of the brake pedal wall.

[0039] Specifically, the limiting member 120 is a bolt. By manually adjusting the limiting member 120, the position of the limiting plate 130 is changed, thereby adjusting the height of the brake pedal wall and changing the braking capability of the forklift.

[0040] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
