[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 The present invention provides a driver's cab for a dynamic compaction machine, which includes a cab shell 1, a self-locking component 2, and a protective component 3.

[0028] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 5 A front beam 11 is fixedly welded to the cab shell 1, and an explosion-proof glass 12 is fixedly installed on it. The top of the cab shell 1 has symmetrically distributed grooves 1a, and the grooves 1a have fixing holes 1b. The cab shell 1 is equipped with a protective component 3 for protecting the explosion-proof glass 12. The protective component 3 includes a curved frame 31. Multiple equally spaced protective rods 33 are fixedly mounted on the curved frame 31, and the protective rods 33 are fitted with rotatably connected rubber sleeves 34. The bottom of the curved frame 31 is fixedly installed with a pressing bottom rod 32 for mounting on a U-shaped support 23. Two symmetrically distributed L-shaped fixing seats 35 are fixedly installed at the upper edge of the curved frame 31, and the L-shaped fixing seats 35 match the grooves 1a.

[0029] It should be noted that when installing the protective component 3 on the cab shell 1, the pressing bottom rod 32 is snapped into the self-locking component 2, and then the L-shaped fixing seat 35 is placed in the groove 1a opened on the top of the cab shell 1. The L-shaped fixing seat 35 is then fixed with screws. The installation operation is simple and allows the curved frame 31 to cover and protect the explosion-proof glass 12.

[0030] It should also be noted that the curved frame 31 is equipped with a protective rod 33, which can effectively protect the cab shell 1. Since the protective rod 33 is fitted with a rotatably connected rubber sleeve 34, and the rubber sleeve 34 itself is elastic, it can effectively reduce the impact force on the protective rod 33, greatly improving the protection of the cab shell 1. When a falling object falls on the front inclined surface of the cab shell 1, since the rubber sleeve 34 has the ability to rotate, after the falling object hits the rubber sleeve 34, its force drives the rubber sleeve 34 to rotate in the inclined direction. Therefore, the falling object can roll down along the rubber sleeve 34 and quickly unload the force on the falling object, effectively protecting the glass on the front side of the cab shell 1.

[0031] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The cab shell 1 is equipped with a self-locking component 2 for clamping the protective component 3. There are two sets of self-locking components 2, and both sets of self-locking components 2 are installed on the front beam 11. The self-locking component 2 includes a mounting box 21, which is fixedly installed in the mounting cavity 11a opened in the front beam 11. A support plate 22 is elastically installed in the mounting box 21, and a U-shaped bearing seat 23 is fixedly installed on the support plate 22. An arc-shaped locking hook 29 for clamping the protective component 3 is also installed in the mounting box 21.

[0032] The support plate 22 has symmetrically distributed arc-shaped locking hooks 29 on both sides of its arc. The connecting end of the arc-shaped locking hooks 29 is fixedly installed with a rotating shaft 27. The rotating shaft 27 is rotatably installed on the inner side wall of the mounting box 21. A gear 28 is fixedly sleeved on the rotating shaft 27. The gear 28 is fixedly installed on the side wall of the support plate 22 and meshes with the gear plate 24. The bottom of the support plate 22 has a mounting hole, and a sliding column 25 is inserted into the mounting hole. The bottom of the sliding column 25 is fixedly connected to the inner bottom wall of the mounting box 21. A spring 26 is sleeved on the sliding column 25. One end of the spring 26 is fixedly connected to the inner bottom wall of the mounting box 21, and the other end of the spring 26 is fixedly connected to the lower plate surface of the support plate 22.

[0033] It should be noted that: before installing the protective component 3, the support plate 22 is driven to slide up to the highest point under the action of the spring 26. At this time, the toothed plates 24 on both sides of the support plate 22 drive the two symmetrically distributed gears 28 to rotate in opposite directions. Therefore, the arc-shaped locking hooks 29 on the two symmetrically distributed rotating shafts 27 open.

[0034] When installing the protective component 3, the pressing base rod 32 at the bottom of the curved frame 31 is placed on the U-shaped support seat 23. Under the weight of the protective component 3, the support plate 22 is driven to slide down the sliding column 25 and compress the spring 26. As a result, the toothed plates 24 on both sides of the support plate 22 drive the two symmetrically distributed gears 28 to rotate in opposite directions. Therefore, the arc-shaped locking hooks 29 on the two symmetrically distributed rotating shafts 27 engage, completing the engagement of the pressing base rod 32. Then, the L-shaped fixing seat 35 is placed into the groove 1a opened on the top of the cab shell 1 and fixed with screws.

[0035] When disassembling the protective component 3, first remove the screws on the L-shaped fixing seat 35, and then use the lifting device to lift the protective component 3, thereby driving the support plate 22 to slide to the highest point under the action of the spring force 26. At this time, the arc-shaped locking hooks 29 on the two symmetrically distributed rotating shafts 27 open, and the disassembly of the protective component 3 can be completed. The overall operation is simple and convenient.

[0036] Furthermore, in order to reduce the problem of decreased locking force caused by fatigue or wear of spring 26, gear 24 and gear 28 due to long-term pressure, high-strength alloy springs and surface-hardened gears are used, and the spring force of spring 26 and the meshing state of gear 24 and gear 28 are checked regularly.

[0037] In this application, a curved frame 31 is combined with multiple equidistant protective rods 33, along with a rotating rubber sleeve 34. The impact force of falling objects is converted into sliding force through the elasticity and rotation characteristics of the rubber, which significantly reduces the risk of glass damage. The designed self-locking component 2 achieves automatic locking and releasing of the protective component 2 through the linkage of gear 28-tooth plate 24 and the elastic support of spring 26, which simplifies the installation process and improves maintenance efficiency.

[0038] The working principle of the dynamic compaction machine cab provided by this utility model is as follows:

[0039] When installing the protective component 3 on the cab shell 1, the pressing bottom rod 32 is engaged with the self-locking component 2, and then the L-shaped fixing seat 35 is placed into the groove 1a opened on the top of the cab shell 1. Specifically, when installing the protective component 3, the pressing bottom rod 32 at the bottom of the curved frame 31 is mounted on the U-shaped support seat 23, so that under the action of the gravity of the protective component 3, the support plate 22 is driven to slide down along the sliding column 25 and compress the spring 26. As a result, the toothed plates 24 on both sides of the support plate 22 drive the two symmetrically distributed gears 28 to rotate in opposite directions. Therefore, the two symmetrically distributed rotating shafts 27 The arc-shaped locking hook 29 engages to lock the bottom rod 32. Then, the L-shaped fixing seat 35 is placed in the groove 1a on the top of the cab shell 1 and fixed with screws. When disassembling the protective component 3, the screws on the L-shaped fixing seat 35 are first removed. Then, the protective component 3 is lifted, and the support plate 22 is slid up to the highest point under the action of the spring force 26. At this time, the arc-shaped locking hooks 29 on the two symmetrically distributed rotating shafts 27 open, and the disassembly of the protective component 3 can be completed. The overall operation is simple and convenient.

[0040] A protective rod 33 is mounted on the curved frame 31. The protective rod 33 can effectively protect the cab shell 1. Since the protective rod 33 is fitted with a rotatably connected rubber sleeve 34, and the rubber sleeve 34 itself is elastic, it can effectively reduce the impact force on the protective rod 33 and greatly improve the protection of the cab shell 1. When a falling object falls on the front inclined surface of the cab shell 1, since the rubber sleeve 34 has the ability to rotate, after the falling object hits the rubber sleeve 34, its force drives the rubber sleeve 34 to rotate in the inclined direction. Therefore, the falling object can roll down along the rubber sleeve 34 and quickly unload the force on the falling object, effectively protecting the glass on the front side of the cab shell 1.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
