Technical Field
[0001] This utility model relates to the field of driver's cabs, and in particular to semi-enclosed driver's cabs for construction machinery. Background Technology
[0002] A semi-enclosed cab combines the advantages of a fully enclosed and an open cab. It is typically used in work environments that require some protection but are not completely enclosed, ensuring safety and ease of operation while also taking into account visibility and ventilation requirements.
[0003] When using construction machinery, a semi-enclosed cab is often used. The operator sits in a seat inside the cab, which has glass at the front and rear, but the sides are not enclosed to maintain a certain level of ventilation and openness. The operator then controls the machinery through control equipment inside the cab. However, in semi-enclosed cabs, the incomplete enclosure of the sides allows external debris, such as falling rocks and construction debris, to easily enter the cab in potentially hazardous working environments. This debris can affect the operator's safety and health, and may also damage the internal equipment, thus compromising the effectiveness of the semi-enclosed cab. Utility Model Content
[0004] The technical problem this utility model aims to solve is that when using a semi-enclosed cab body, the two sides of the cab body are not completely sealed, which makes it easy for external debris to enter the cab body through the two sides in a relatively dangerous working environment. This debris can affect the safety and health of the operators and may also damage the internal equipment, thereby affecting the effectiveness of the semi-enclosed cab.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a semi-enclosed cab for engineering machinery, including a cab body, a seat is provided inside the cab body, glass is provided at the front and rear ends of the cab body, and protective devices are provided on both sides of the cab body. The protective devices use protective plates to shield and protect the sides of the cab body.
[0006] Preferably, the protective device includes a slide rail, a protective plate, a connecting plate, a fixing plate, bolts, and through holes on both sides of the connecting plate. The slide rail is disposed on both sides of the cab body, the protective plate slides inside the slide rail, the two ends of the connecting plate are connected to the protective plate and penetrate one side of the cab body, the fixing plate is disposed inside the cab body, and the bolts are threaded into the fixing plate and reach the through holes on one side of the connecting plate to engage with the connecting plate.
[0007] Preferably, the protective plate is provided with observation windows on both sides, so that the operator can observe the environment on both sides of the cab through the observation windows.
[0008] Preferably, a control frame is provided at one end of the connecting plate inside the cab body, and the control frame increases the size of one side of the connecting plate.
[0009] Preferably, the surface of the control frame is provided with a plurality of anti-slip blocks to increase the friction of the control frame surface.
[0010] Preferably, the fixing plate is provided with a connecting rope on the side near the bolt, and one side of the connecting rope is connected to the bolt.
[0011] Preferably, the two protective plates are provided with rubber pads on one side close to each other to improve the sealing of the two protective plates and both sides of the cab body.
[0012] Preferably, the upper ends of the two protective plates are provided with reinforcing frames, which support the distance between the upper ends of the two protective plates.
[0013] In summary, the beneficial effects of this utility model are as follows:
[0014] By using protective devices, the sides of the semi-enclosed cab can be shielded and protected, preventing external debris from entering the cab through the sides in a relatively dangerous working environment, thus avoiding any impact on the safety and health of the operators and the equipment inside the cab, thereby improving the effectiveness of the semi-enclosed cab.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] Figures 1 to 6 The semi-enclosed cab for construction machinery shown includes a cab body 1, a seat 2 inside the cab body 1, glass 3 at the front and rear ends of the cab body 1, and protective devices 4 on both sides of the cab body 1. The protective devices 4, through protective plates 42, provide shielding protection to the sides of the cab body 1. When using the construction machinery, the semi-enclosed cab is used. The operator sits in the seat 2 inside the cab body 1. The front and rear ends of the cab body 1 are fitted with glass 3, while the sides are not enclosed to maintain a certain degree of ventilation and openness. The operator then controls the machinery through the control equipment inside the cab body 1. When working in more hazardous environments, the protective devices 4 are used to shield the sides of the semi-enclosed cab.
[0026] Figures 1 to 6 The protective device 4 shown includes a slide rail 41, a protective plate 42, a connecting plate 43, a fixing plate 44, bolts 45, and through holes 46 on both sides of the connecting plate 43. The slide rail 41 is arranged on both sides of the cab body 1. The protective plate 42 slides inside the slide rail 41. The two ends of the connecting plate 43 are connected to the protective plate 42 and pass through one side of the cab body 1. The fixing plate 44 is arranged inside the cab body 1. The bolts 45 are threaded into the fixing plate 44 and reach the through holes 46 on one side of the connecting plate 43, and are engaged with the connecting plate 43.
[0027] Figures 1 to 6When using the protective device 4, the operator moves the connecting plate 43 inside the cab body 1, causing the connecting plate 43 to slide inside the cab body 1. Then, the protective plates 42 fixed at both ends of the connecting plate 43 are slid along the slide rails 41 fixed on both sides of the cab body 1. The protective plates 42 then shield and protect both sides of the cab body 1. Next, the bolt 45 is rotated, causing the bolt 45 to rotate within the threaded fixing plate 44 fixed inside the cab body 1. The bolt 45 reaches the through hole 46 on one side of the connecting plate 43 to engage and fix it. This completes the fixing of the protective plate 42. By using the protective device 4, the sides of the semi-enclosed cab can be shielded and protected, preventing external debris from entering the cab body 1 through the sides in a relatively dangerous working environment, thus avoiding impact on the safety and health of the operator and the equipment inside the cab, thereby improving the effectiveness of the semi-enclosed cab.
[0028] Figures 1 to 6 The protective plate 42 shown has observation windows 47 on both sides, allowing operators to observe the environment on both sides of the cab body 1 through the observation windows 47. By fixing the observation windows 47 to both sides of the protective plate 42, the protective plate 42, after completing the shielding and protection of both sides of the cab body 1, does not affect the operator's subsequent observation of the buffer area on both sides of the cab body 1, thereby improving the usability of the observation windows 47. A control frame 48 is provided at one end of the connecting plate 43 inside the cab body 1. The control frame 48 raises the size of one side of the connecting plate 43. By fixing the control frame 48 to one side of the connecting plate 43, the size of one side of the connecting plate 43 is raised, allowing the operator to hold the control frame 48 and move the connecting plate 43 more easily.
[0029] Figures 1 to 6 The control frame 48 shown has several anti-slip blocks 49 on its surface to increase friction. By fixing these anti-slip blocks 49 to the surface of the control frame 48, the increased friction allows the operator to grip the control frame 48 more firmly, thus improving its usability. A connecting rope 410 is provided on the fixing plate 44 near the bolt 45, with one side of the rope connected to the bolt 45. The connecting rope 410 is secured to both ends of the bolt 45 and the fixing plate 44, thus connecting and securing the bolt 45 and the fixing plate 44. This prevents the bolt 45 from being lost, which could affect the subsequent fixing of the connecting plate 43, thereby improving the usability of the bolt 45.
[0030] Figures 1 to 6Rubber pads 411 are provided on the side of the two protective plates 42 that are close to each other to improve the sealing of the two protective plates 42 and both sides of the cab body 1. By fixing the rubber pads 411 to the two protective plates 42 on the side of their close proximity, when the protective plates 42 are used to shield and protect the cab body 1, the rubber pads 411 seal the contact area between the two, preventing small debris from entering through the gap between them, thereby improving the effectiveness of the protective plates 42. Reinforcing frames 412 are provided at the upper ends of the two protective plates 42, supporting the gap between the upper ends of the two protective plates 42. By fixing the reinforcing frames 412 to the upper ends of the two protective plates 42, the reinforcing frames 412 support the gap between the upper ends of the two protective plates 42, preventing the upper ends of the two protective plates 42 from deforming under stress, which would affect the use of the protective plates 42.
[0031] Working principle: When using construction machinery, a semi-enclosed cab is used. The operator sits on the seat 2 inside the cab body 1. Glass 3 is installed at the front and rear ends of the cab body 1, and the sides are not enclosed to maintain a certain degree of ventilation and openness. The operator then controls the machinery through the control equipment inside the cab body 1. When working in a more dangerous working environment, protective devices 4 are used to shield and protect the sides of the semi-enclosed cab. When using the protective device 4, the operator moves the connecting plate 43 inside the cab body 1, causing the connecting plate 43 to slide inside the cab body 1. Then, the protective plates 42 fixed at both ends of the connecting plate 43 will slide along the slide rails 41 fixed on both sides of the cab body 1. The protective plates 42 then shield and protect both sides of the cab body 1. Next, the bolt 45 is rotated, causing the bolt 45 to rotate inside the fixing plate 44 fixed inside the cab body 1. The bolt 45 reaches the through hole 46 on one side of the connecting plate 43 to engage and fix it. Then, the position of the protective plate 42 is fixed. At this time, the rubber pad 411 seals the contact area between the two to prevent small debris from entering through the gap between them. By using the protective device 4, the sides of the semi-enclosed cab can be shielded and protected, preventing external debris from entering the cab body 1 through the sides in a more dangerous working environment, thus avoiding the safety and health of the operator and the equipment inside the cab, thereby improving the use effect of the semi-enclosed cab.

However, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the utility model's technical solution, shall still fall within the protection scope of this utility model's technical solution. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.
