Description

Technical Field

[0001] The utility model relates to the technical field of operating mechanism fixing devices, in particular to an operating mechanism fixing device, a cab and an engineering vehicle. Background Art

[0002] The control mechanism is the mechanism used to change the gear pairing in the transmission to achieve the shifting function. Off-highway dump trucks operate in harsh environments, so the matching control mechanism lacks synchronizers. This results in the driver requiring greater control force when shifting gears, seriously affecting the driver's driving experience.

[0003] In manual transmission design, a longer shift lever is often used to increase the shift lever ratio to reduce shifting effort. This increased lever ratio reduces the driver's shifting effort, but this also increases the height of the shift knob and the shift travel. Because other switches are located on the fixed plate within the dump truck's cab, the height of the fixed plate cannot be adjusted. This results in the shift knob being too high relative to the fixed plate, affecting the driver's driving and other operating experience.

[0004] Off-highway dump trucks are generally used for transportation operations in mining areas. The roads in mining areas are mostly gravel roads, and the working environment is dusty. The original operating mechanism is a semi-sealed structure. Dust will inevitably rush into the cab through the dust cover, causing dust leakage at the seal between the cab and the controller, seriously affecting the driver's driving experience.

[0005] In addition, the structures of manipulators from different suppliers or specifications are different, making them difficult to adapt to the standard cab type. Utility Model Content

[0006] The purpose of the present utility model is to provide a control mechanism fixing device, which aims to solve or at least partially solve the shortcomings of the above-mentioned background technology. It can reduce the height of the gear shift hand ball, improve the adaptability of controllers of different suppliers or specifications to the cab, and solve the problem of dust leakage at the seal between the cab and the controller.

[0007] A control mechanism fixing device is arranged on the cab floor and is used to install the control mechanism. The control mechanism fixing device includes an upper shell arranged on the lower surface of the cab floor and a lower baffle arranged at the bottom of the upper shell. The upper shell and the lower baffle together form a cavity. The lower baffle is used to install a manipulator of the control mechanism. The lower baffle is penetrated by a matching hole that matches the manipulator. At least part of the manipulator passes upward through the matching hole and protrudes from the cavity. The upper shell is provided with a through hole. The through hole is used to avoid a shift rod and / or manipulator connected to the manipulator.

[0008] Furthermore, the upper shell and the lower baffle are an integrally formed structure or are fixedly connected by welding or are detachably fixedly connected.

[0009] Furthermore, at least one first mounting hole is formed on the upper surface of the upper shell around the through hole, and the first mounting hole is used for mounting the upper shell.

[0010] Furthermore, the lower baffle is provided with at least one second mounting hole surrounding the matching hole, and the second mounting hole is used for mounting the manipulator.

[0011] Furthermore, at least one third mounting hole is formed on the upper surface of the upper shell around the through hole, and the third mounting hole is used for mounting a dust cover of the operating mechanism.

[0012] Furthermore, the third mounting hole passes through the upper shell, and the upper shell is provided with a mounting nut at the lower end of the third mounting hole.

[0013] Furthermore, a sealing structure is provided on the circumferential edge of the lower baffle surrounding the matching hole, and the sealing structure abuts against the manipulator.

[0014] Furthermore, a sealing structure is provided on the upper surface of the upper shell, and the sealing structure abuts against the lower surface of the cab floor.

[0016] An engineering vehicle comprises the above-mentioned cab.

[0017] The control mechanism fixing device provided by the present invention adds a control mechanism fixing device between the manipulator and the cab floor. The height of the control mechanism fixing device can be matched according to the height of the fixing plate, and the installation point of the manipulator can be sunk, thereby causing the shift hand ball to sink to a suitable position, shortening the distance between the shift hand ball and the fixing plate, meeting ergonomic requirements, and facilitating the driver's operation of the operating hand ball, rocker switch and control handle, making the driver's operation more comfortable; through the close cooperation between the lower baffle and the manipulator, the lower baffle can block dust from entering the cab, greatly reducing the dust leakage problem; in addition, the opening shape of the matching hole of the lower baffle can be matched according to manipulators of different suppliers or specifications, increasing the versatility of the cab design and the adaptability of the manipulator.

[0024] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms "up," "down," "left," "right," "front," "back," "top," and "bottom" (if any) used in the specification and claims of this utility model are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are intended solely for clarity and convenience in presenting the technical solution. It should be understood that the use of these terms does not limit the scope of protection claimed in this application.

[0027] See also Figure 1-Figure 3 It should be noted that, in the prior art, the operating mechanism 20 is mounted on the cab floor 30, and the operating mechanism 20 includes a manipulator 21, a shift lever 22, a shift hand ball 23 and a dust cover 24. The manipulator 21 is mounted on the cab floor 30, and the upper end of the manipulator 21 is connected to the shift lever 22, and the shift lever 22 protrudes above the cab floor 30. The upper end of the shift lever 22 is mounted with a shift hand ball 23, and the dust cover 24 is mounted on the upper surface of the cab floor 30 and is used to block dust.

[0028] In addition, a rocker switch 60 and a manipulation handle 50 are arranged on one side of the manipulation mechanism 20. The rocker switch 60 and the manipulation handle 50 are set on the fixed plate 40 of the cab. The fixed plate 40 is located above the cab floor 30 and the height is fixed and cannot be adjusted.

[0029] In the prior art, in order to reduce the gear shifting operating force, engineers would choose a longer gear shift lever 22 to increase the gear shift lever ratio and thus reduce the operating force required by the driver when shifting gears. However, this results in the height of the gear shift ball 23 being too high, which increases the distance between the gear shift ball 23 and the fixed plate 40, making it extremely inconvenient for the driver to operate the gear shift ball 23 and the rocker switch 60 or the operating handle 50 in sequence.

[0030] See also Figure 4-Figure 6 The present invention provides a control mechanism fixing device 10 , which is arranged on the cab floor 30 and is used to install the control mechanism 20 .

More specifically, the through-hole 111 of the upper housing 11 provides a wrench space to facilitate disassembly and maintenance of the manipulator 21 mounted on the lower baffle 12, as well as disassembly and assembly of the flexible shaft connected to the manipulator 21.

[0037] At least one third mounting hole 113 is defined on the upper surface of the upper housing 11 around the through hole 111 . The dust cover 24 of the operating mechanism is mounted on the upper housing 11 through the third mounting hole 113 .

[0038] In this embodiment, the third mounting hole 113 passes through the upper housing 11 , and the third mounting hole 113 is used to mount the dust cover 24 of the operating mechanism 20 .
