Description

Technical Field

[0001] This utility model belongs to the technical field of driver's cabs, and particularly relates to a driver's cab equipped with a protective canopy. Background Technology

[0002] A patent titled "A Cab Canopy" is disclosed in the existing Chinese patent database, with application number CN202222544801.7 and application date of 2022-09-26. This cab canopy belongs to the technical field of cab canopy devices. It includes two frames arranged opposite each other. Support plates are installed on the inner walls of the two frames near their front sides. Support seats are fixed to the left and right sides of the support plates by bolts. A hydraulic cylinder is rotatably mounted on the top of the support seat, and a front support is rotatably mounted on the top of the hydraulic cylinder. Fixing seats are fixed on the left and right sides of the two frames, located on the back side of the support seats. Fixing frames are mounted on the fixing seats, and adjusting frames are movably mounted inside the fixing frames. The fixing frames and adjusting frames are locked and positioned by bolts. This design allows for adjustment of the canopy angle, expanding the operator's field of vision and facilitating accurate lifting of goods. Furthermore, the canopy height can be adjusted according to the height of different operators, increasing the canopy's applicability and ease of use.

[0003] The existing cab lacks a protective canopy. In special operations such as demolition or underground mining, debris constantly impacts the canopy. Over time, dents inevitably appear on the canopy, and debris easily accumulates there. Moreover, the horizontal canopy itself is prone to accumulating debris. If personnel exit the cab and the debris suddenly falls, it could injure them below, posing a safety hazard. Therefore, this paper aims to propose a cab equipped with a protective canopy that can rotate to dump debris and prevent its accumulation above the cab. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cab equipped with a rotatable protective canopy to prevent gravel from accumulating on the top of the cab during operation. In order to improve its shortcomings, this utility model provides a cab equipped with a protective canopy.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A cab equipped with a protective canopy includes a cab body, a hinge seat is provided at the rear end of the cab body, a canopy body is hinged to the hinge seat, the canopy body is L-shaped, the vertical section of the canopy body is hinged to the hinge seat, and an angle adjustment component is provided at the top of the cab body located below the canopy body, the angle adjustment component is hinged to the lower surface of the horizontal section of the canopy body.

[0007] As a preferred embodiment, the angle adjustment component includes a frame fixed to the top of the cab body, a slider horizontally slidably connected inside the frame, a lead screw inserted inside the slider, the lead screw and the slider cooperating to form a lead screw transmission mechanism, a horizontal waist-shaped groove is opened on the side of the frame, a shaft extending integrally through the waist-shaped groove on the side of the slider, a connecting rod is hinged on the shaft, and the other end of the connecting rod is hinged to the lower surface of the horizontal section of the roof body.

[0008] As a preferred embodiment, a drive motor is installed on the top of the cab body, and the output section of the drive motor is connected to the free end of the lead screw passing through the frame.

[0009] As a preferred embodiment, the cab body has longitudinally spaced support rods at the front end of the top, and a longitudinal horizontal crossbar is fixedly connected between the two support rods. A rubber pad is fitted on the outer circumference of the crossbar. When the roof is set in a horizontal state, the lower surface of the roof overlaps the outer circumference of the crossbar.

[0010] As a preferred embodiment, the outer side of the frame is integrally provided with several connecting flanges, and each connecting flange is fixed to the top of the cab body by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Due to the cooperative arrangement of the roof body and the angle adjustment component on the top of the cab, the angle of the originally horizontal roof body can be adjusted, so that the gravel piled on the roof body slides down due to its own gravity. The driver only needs to complete the operation of rotating the roof body before getting off the vehicle. At the same time, the cooperative arrangement of the support rod and the crossbar ensures that when the roof body is in a horizontal state, the crossbar is subjected to the gravity of the roof body, avoiding its action on the connecting rod, thus improving the service life of the entire angle adjustment component. This device is suitable for industrial production and has strong practicality. Attached Figure Description

[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-2 As shown, a cab equipped with a protective canopy includes a cab body 1. A hinge seat 2 is located at the rear end of the cab body 1, and a canopy 3 is hinged to the hinge seat 2. The canopy 3 is L-shaped, with its vertical section hinged to the hinge seat 2. An angle adjustment component 4 is located on the top of the cab body 1 below the canopy 3, and is hinged to the lower surface of the horizontal section of the canopy 3. The angle adjustment component 4 includes a frame 5 fixed to the top of the cab body 1. A slider 6 is horizontally slidably connected within the frame 5, and a lead screw 7 is inserted within the slider 6. The lead screw 7 and the slider 6 cooperate to form a screw drive mechanism. A horizontal waist-shaped groove 8 is formed on the side of the frame 5. A shaft 9 extends integrally from the side of the slider 6, passing through the waist-shaped groove 8. A connecting rod 10 is hinged to the shaft 9, and the other end of the connecting rod 10 is hinged to the lower surface of the horizontal section of the canopy 3. A drive motor 11 is installed on the top of the cab body 1, and the output section of the drive motor 11 is connected to the free end of the lead screw 7 passing through the frame 5. Support rods 12 are longitudinally spaced at the front end of the top of the cab body 1, and a longitudinal horizontal crossbar 13 is fixedly connected between two support rods 12. Rubber pads are fitted onto the outer circumference of the crossbar 13. When the canopy 3 is horizontal, the lower surface of the canopy 3 overlaps the outer circumference of the crossbar 13. Several connecting flanges 14 are integrally provided on the outer side of the frame 5, and each connecting flange 14 is fixed to the top of the cab body 1 by bolts.

[0017] When this utility model is in operation, the driver adjusts the angle of the canopy 3, which is originally in a horizontal state. Specifically, the drive motor 11 is controlled to work, driving the lead screw 7 to rotate. The lead screw 7 drives the slider 6 to slide horizontally to the right. During the sliding process, the connecting rod 10 swings counterclockwise, thereby driving the canopy 3 to rotate clockwise, so that the canopy 3 is tilted upward. The gravel piled on top of the canopy 3 slides down due to its own weight, preventing the gravel on the top from falling and hitting the driver when he gets out of the vehicle, thus improving safety. After the canopy 3 is tilted, the drive motor 11 is controlled to reverse, causing the lead screw 7 to drive the slider 6 to slide horizontally to the left, thereby restoring the canopy 3 to its original position. The free end of the canopy 3 is set to overlap the crossbar 13, avoiding the connecting rod 10 from bearing the weight of the canopy 3 and improving the service life of the angle adjustment component 4.

[0018] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
