Description
Technical Field
[0001] This invention relates to the field of mining vehicle cab technology, and in particular to a vibration-damping and impact-resistant mining vehicle cab. Background Technology
[0002] A mining vehicle cab is a dedicated space in the mining industry that provides drivers with operation, control, and protection. It is commonly used in various mining transport vehicles, such as mining trucks, loaders, mining cars, and bulldozers. Mining vehicle cabs must possess sufficient impact and compressive strength to prevent injury to the driver in the event of accidents in harsh mining environments, especially during underground operations.
[0003] The cab of a mining vehicle is not only the place where the driver operates the vehicle, but also an integrated complex design that combines safety and comfort. It must meet requirements in multiple aspects, including protective functions, comfort, visibility, intelligent control, and safety, to ensure that the driver can complete the work efficiently and safely in complex and harsh mining environments.
[0004] When existing mining loaders are shoveling or loading ore, there is a risk of ore falling when the bucket is raised. The front of the cab of existing mining loaders lacks a function to prevent falling ore, which may damage the windshield or other parts, potentially causing safety hazards to the driver, increasing equipment maintenance costs, and reducing work efficiency.
[0005] In summary, the existing technology lacks a technology to protect mining loaders from falling ore from the bucket. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a vibration-damping and impact-resistant mining vehicle cab.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a vibration-damping and impact-resistant mining vehicle cab, including a mining shovel, a cab protective frame is fixedly installed on the mining shovel, a bucket arm is rotatably connected to one side of the mining shovel, a drive mechanism is fixedly connected to one side of the bucket arm, a mounting frame is fixedly connected to the cab protective frame, a stop is rotatably connected to the mounting frame, an ore baffle is provided on the stop, an ore pushing mechanism is rotatably connected to the stop, and a guide rail seat is fixedly connected to the mining shovel.
[0008] Preferably, the drive mechanism includes a rotating seat, one end of which is fixedly connected to one end of the bucket arm. A fixed shaft is fixedly connected to the rotating seat in an eccentric structure, and a push-pull rod is rotatably connected to the outer end of the fixed shaft.
[0009] Preferably, a sliding seat is rotatably connected to the other end of the push-pull rod, the sliding seat is slidably engaged with the guide rail seat, and a transmission rack is fixedly connected to the sliding seat.
[0010] Preferably, a worm gear is fixedly connected to one end of the stop and the mounting bracket, and two sliding grooves are provided on both sides of the stop.
[0011] Preferably, a plurality of vibration damping rods are rotatably connected to one side of the ore baffle, and a slider is rotatably connected to the other end of the vibration damping rod. The slider is slidably engaged with the inner wall of the chute. A spring is fixedly connected to one side of the slider, and the other end of the spring is fixedly connected to the inner wall of the chute. A triangular baffle is fixedly connected to one end of the ore baffle, and the triangular baffle is slidably engaged with the baffle frame. A metal mesh is fixedly connected to the opening of the ore baffle.
[0012] Preferably, the ore pushing mechanism includes two linkage groups. One end of each linkage group is rotatably connected to the inner wall of the baffle. A gear is fixedly connected to one end of each linkage group. The two gears mesh with each other for transmission. One end of one linkage group is fixedly connected to a rotating shaft. The other end of the rotating shaft passes through the inner wall of the baffle and extends to the outside, where a transmission wheel is fixedly connected.
[0013] Preferably, a pusher plate is rotatably connected to the other end of the linkage assembly. A limit block is fixedly connected to one end of the pusher plate, and the limit block is slidably engaged with the baffle. A guardrail is fixedly connected to one side of the pusher plate, and a movable plate is slidably engaged with the inner wall of one side of the pusher plate. The movable plate is in slidable contact with the ore baffle. A tension spring is fixedly connected to the inner end of the movable plate, and the other end of the tension spring is fixedly connected to the inner wall of the pusher plate.
[0014] Preferably, an arc-shaped rack is fixedly connected to the guide rail base, and the arc-shaped rack meshes with the transmission wheel for transmission.
[0015] Preferably, a universal joint is rotatably connected to the guide rail base, an adjusting wheel is fixedly connected to the universal joint, the adjusting wheel meshes with a transmission rack, the other end of the universal joint is rotatably connected to the cab protective frame, a transmission rod is fixedly connected to the other end of the universal joint, a worm gear is fixedly connected to the other end of the transmission rod, the other end of the worm gear is rotatably connected to the cab protective frame, and the worm gear meshes with a worm wheel.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. When the bucket arm lifts the bucket, the rotatable baffle is used to block the front of the cab. At the same time, the ore baffle can block and buffer the ore falling from the bucket, preventing the ore from hitting the cab. This can effectively reduce the direct injury to the driver from falling ore and ensure the driver's safety. The ore baffle not only blocks falling ore, but also reduces the intensity of the ore impact on the loader cab or equipment through the buffering effect, reducing the risk of equipment damage and improving work efficiency.
[0018] 2. By setting up an ore pushing mechanism, when the guard is rotated upward to reset, the stones that fall onto the guard and ore baffle will be automatically pushed down, ensuring that no ore accumulates on the guard and ore baffle of the loader after each operation. This avoids the extra burden of ore on the equipment, reduces the need for manual cleaning, and lowers the risk of equipment damage and failure, thereby improving the safety, efficiency and reliability of the mining loader.
[0019] 3. By setting up a drive mechanism, the bucket arm can automatically extend and retract the guard while lifting the bucket, realizing automated operation of the bucket and guard without manual control. This avoids safety hazards caused by forgetting to operate the equipment, greatly improving the working efficiency and operating accuracy of the construction machinery. At the same time, by setting up guardrails, rocks falling onto the ore guard can be blocked, preventing rocks from flying to other locations and causing safety hazards, further improving the safety of the loader during use.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0030] like Figures 1-8 The image shows a vibration-damping and impact-resistant mining vehicle cab, including a mining shovel 1. A cab protective frame 2 is fixedly installed on the mining shovel 1. A bucket arm 3 is rotatably connected to one side of the mining shovel 1. A drive mechanism 4 is fixedly connected to one side of the bucket arm 3. A mounting frame 5 is fixedly connected to the cab protective frame 2. A baffle 6 is rotatably connected to the mounting frame 5. An ore baffle 7 is installed on the baffle 6. An ore pushing mechanism 8 is rotatably connected to the baffle 6. A guide rail seat 9 is fixedly connected to the mining shovel 1.
[0031] like Figure 4 As shown, the drive mechanism 4 includes a rotating seat 401. One end of the rotating seat 401 is fixedly connected to one end of the bucket arm 3. A fixed shaft 402 is fixedly connected to the rotating seat 401 in an eccentric structure. A push-pull rod 403 is rotatably connected to the outer end of the fixed shaft 402.
[0032] The other end of the push-pull rod 403 is rotatably connected to a sliding seat 404, which is slidably engaged with the guide rail seat 9. A transmission rack 405 is fixedly connected to the sliding seat 404. When the bucket arm 3 lifts the bucket loaded with ore, it will cause the connected rotating seat 401 to rotate. At this time, the rotating seat 401 will drive the push-pull rod 403 to move through the fixed shaft 402, so that the push-pull rod 403 drives the sliding seat 404 to slide on the guide rail seat 9, thereby driving the connected transmission rack 405 to move.
[0033] like Figure 5 As shown, a worm gear 601 is fixedly connected to one end of the baffle 6 and the mounting bracket 5, and two sliding grooves 602 are opened on both sides of the baffle 6.
[0034] like Figure 6 As shown, multiple damping rods 701 are rotatably connected to one side of the ore baffle 7, and a slider 702 is rotatably connected to the other end of each damping rod 701. The slider 702 is slidably engaged with the inner wall of the slide groove 602. A spring 703 is fixedly connected to one side of the slider 702, and the other end of the spring 703 is fixedly connected to the inner wall of the slide groove 602. A triangular baffle 704 is fixedly connected to one end of the ore baffle 7, and the triangular baffle 704 is slidably engaged with the baffle frame 6. A metal mesh 705 is fixedly connected to the opening of the ore baffle 7. When stones fall, they will land on the ore baffle 7, and the damping rods 701 will drive the slider 702 to move within the slide groove 602, where it will be cushioned by the action of the spring 703.
[0035] like Figure 7 As shown, the ore pushing mechanism 8 includes two linkage groups 801. One end of the linkage group 801 is rotatably connected to the inner wall of the baffle 6. A gear 802 is fixedly connected to one end of the linkage group 801. The two gears 802 mesh with each other for transmission. One end of one linkage group 801 is fixedly connected to a rotating shaft 803. The other end of the rotating shaft 803 extends through the inner wall of the baffle 6 to the outside and is fixedly connected to a transmission wheel 804.
[0036] A pusher plate 805 is rotatably connected to the other end of the linkage assembly 801. A limit block 809 is fixedly connected to one end of the pusher plate 805. The limit block 809 is slidably engaged with the baffle 6. A guardrail 806 is fixedly connected to one side of the pusher plate 805. A movable plate 807 is slidably engaged with the inner wall of one side of the pusher plate 805. The movable plate 807 is slidably in contact with the ore baffle 7. A tension spring 808 is fixedly connected to the inner end of the movable plate 807. The other end of the tension spring 808 is fixedly connected to the inner wall of the pusher plate 805. When the baffle 6 rotates upward to reset, the arc-shaped rack 901 will drive the transmission wheel 804 to rotate, which will drive the gear 802 connected to the shaft 803 to rotate. This gear 802 will then drive another gear 802 to rotate, thereby causing the two linkage groups 801 to move the pusher plate 805. In conjunction with the movable plate 807 connected to the tension spring 808, the ore that has fallen onto the baffle 6 and the ore baffle 7 will be automatically pushed down.
[0037] like Figure 8 As shown, an arc-shaped rack 901 is fixedly connected to the guide rail seat 9, and the arc-shaped rack 901 meshes with the transmission wheel 804 for transmission.
[0038] A universal joint 902 is rotatably connected to the guide rail seat 9. An adjusting wheel 903 is fixedly connected to the universal joint 902. The adjusting wheel 903 meshes with the transmission rack 405 for transmission. The other end of the universal joint 902 is rotatably connected to the cab protective frame 2. A transmission rod 904 is fixedly connected to the other end of the universal joint 902. A worm gear 905 is fixedly connected to the other end of the transmission rod 904. The other end of the worm gear 905 is rotatably connected to the cab protective frame 2. The worm gear 905 meshes with the worm wheel 601 for transmission. When the transmission rack 405 moves, it drives the adjusting wheel 903 to rotate, which in turn drives the universal joint 902 to rotate. This causes the universal joint 902 to drive the worm gear 905 connected to the transmission rod 904 to rotate, which in turn drives the stop 6 connected to the worm wheel 601 to rotate and lower.
[0039] Working principle: During the use of the mining loader 1, when the control of the bucket arm 3 drives the bucket loaded with ore to lift, it will drive the connected rotating seat 401 to rotate. At this time, the rotating seat 401 will drive the push-pull rod 403 to move through the fixed shaft 402, so that the push-pull rod 403 drives the sliding seat 404 to slide on the guide rail seat 9, thereby driving the connected transmission rack 405 to move.
[0040] When the transmission rack 405 moves, it will drive the adjusting wheel 903 to rotate, which will cause the adjusting wheel 903 to drive the connected universal joint 902 to rotate, which will cause the universal joint 902 to drive the worm gear 905 connected to the transmission rod 904 to rotate, which will cause the worm gear 905 to drive the stop 6 connected to the worm wheel 601 to rotate and lower, so that the ore baffle 7 blocks in front of the cab of the mining loader 1.
[0041] When stones fall from the bucket, they will land on the ore baffle 7. The damping rod 701 will drive the slider 702 to move in the slide groove 602. Under the action of the spring 703, the stones will be buffered to achieve the function of vibration reduction and impact resistance. Then, the stones will roll down to the lower end of the baffle 6 under the obstruction of the guardrail 806.
[0042] Then, when the bucket arm 3 lowers the bucket loaded with ore, it will cause the retaining frame 6 to rotate upward and reset. At this time, under the action of the arc rack 901, it will drive the transmission wheel 804 to rotate, which will drive the gear 802 connected to the rotating shaft 803 to rotate. At this time, the gear 802 will drive another gear 802 to rotate, thereby causing the two connecting rod groups 801 to drive the pusher plate 805 to move. In conjunction with the movable plate 807 connected by the tension spring 808, the ore that falls on the retaining frame 6 and the ore retaining plate 7 will be automatically pushed down, which will facilitate the rotation and reset of the retaining frame 6.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
