Description

Technical Field

[0001] This utility model belongs to the field of loader technology, specifically relating to a loader cab safety net and a loader. Background Technology

[0002] Currently, loader cab safety nets are mainly divided into two types based on their structural form: non-openable and openable. Each type has its own characteristics in terms of functionality and applicability.

[0003] (1) Non-openable protective netting

[0004] This type of protective netting adopts an integral welded structure, with the main frame and the netting fixedly connected by welding to form a non-removable integrated protective component. Its advantages lie in its simple structure, high rigidity, and low manufacturing cost, making it widely used in existing loader cabs. However, this design has significant functional defects: because the netting cannot be opened, cleaning and maintaining the cab glass is difficult, especially in extremely cold conditions where the glass surface is prone to icing. The fixed netting severely obstructs the working space for de-icing tools, thus affecting the driver's visibility and operational efficiency.

[0005] (2) Openable protective net

[0006] The openable protective netting employs a hinged connection and fastening locking mechanism. One end of the netting is hinged to the main frame, while the other end is detachably fixed using a locking device (such as bolts or quick-release buckles), thus enabling the netting to rotate and open around the hinge axis. Based on the opening direction, it can be further subdivided into the following two categories:

[0007] 1) Front protective netting can be opened

[0008] Top and bottom opening type: Due to structural interference from the cab roof or lights, the opening angle of the safety net is limited, affecting the convenience of actual operation.

[0009] Left and right opening type: Although the opening angle is large, the space between the hinge rotation axis and the main frame is cramped due to the usually inclined arrangement, making it difficult to integrate an effective limiting device, resulting in insufficient stability after the guardrail is opened.

[0010] 2) Openable side guard net: This type of guard net has a small area and although it has an opening function, it is difficult to cover the de-icing needs of the windshield, so its practical application value is limited.

[0011] In summary, the existing protective netting designs for loader cabs still have significant shortcomings in terms of functionality, ergonomics, and environmental adaptability: non-openable netting has poor maintainability and cannot adapt to extreme working conditions; openable netting is limited by structure, or has insufficient opening angle, or lacks limiting stability, making it difficult to balance protective performance and ease of operation. Utility Model Content

[0012] One of the purposes of this utility model is to disclose a loader cab safety net that is hinged to the main frame on the first side, so that the front safety net can be opened to the side, thus solving the problem in the prior art that the loader cab safety net is difficult to open or the opening angle is limited, making it difficult to clean the cab glass.

[0013] To achieve the above objectives, this utility model discloses a protective net for a loader cab, including a main frame and a front protective net, wherein the front protective net is installed on the main frame; the front protective net includes a first side, which is inclined and hinged to the main frame; the front protective net rotates around the position where the first side is hinged to the main frame to open the front protective net laterally.

[0014] As an optional implementation, a hinge is fixedly installed on the first side, and the hinge is also fixedly installed to the main frame.

[0015] As an optional implementation, the front guard also includes a second side, on which a lock is installed to lock the front guard to the main frame.

[0016] As an optional implementation, the lock includes a lock pin and a lock body. The lock pin is fixedly installed on the second side, and the lock body is fixedly installed on the main frame. The position of the lock body is adapted to the position of the lock pin.

[0017] As an optional implementation, the loader cab safety net also includes a limiting mechanism for limiting the angle at which the front safety net opens laterally. The limiting mechanism includes a first end and a second end, the first end being installed on the front safety net and the second end being installed on the main frame. After the front safety net is opened, the limiting mechanism maintains a fixed distance between the first end and the second end.

[0018] As an optional implementation, the limiting mechanism includes a gas spring, with the two ends of the gas spring being a first end and a second end, respectively. The first end is rotatably connected to the front guard net, and the second end is rotatably connected to the main frame.

[0019] As an optional implementation, the front protective net includes a lower side side one, and a first end is connected to the lower side side one; the main frame includes a lower side side two, and a second end is connected to the lower side side two.

[0020] As an optional implementation, the first end is connected to a fisheye connector one, the second end is connected to a fisheye connector two, the fisheye connector one is installed with the front guard net, and the fisheye connector two is installed with the main frame.

[0021] As an optional implementation, the loader cab safety net also includes a vibration damping mechanism, which includes a vibration damping pad fixedly mounted on the main frame. When the front safety net is closed, at least a portion of the front safety net is in contact with the vibration damping pad.

[0022] The second objective of this utility model is to disclose a loader that includes the aforementioned protective netting in the loader cab. The use of this protective netting in the loader cab makes the cab glass easy to clean and facilitates de-icing operations, thereby improving work efficiency.

[0023] Compared with the prior art, the beneficial effects of this utility model of a loader cab protective net are as follows: the loader cab protective net is hinged to the main frame through the first side of the front protective net, so that the front protective net can be opened laterally and outward at a large angle, which facilitates the de-icing, cleaning and other operations of the cab glass protected by the front protective net, thereby improving work efficiency.

[0024] Compared with the prior art, the beneficial effects of this loader are as follows: the aforementioned protective net is used in front of the cab of the loader, which makes the cab glass easy to clean and easy to de-ice, thus improving work efficiency. Attached Figure Description

[0035] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0036] Please see Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a protective net for a loader cab. Figure 1 The front protective netting 2 is in the open position. Figure 2 This is the front view of the protective netting with the front protective netting 2 closed.

[0037] See Figure 1 A loader cab safety net includes a main frame 1 and a front safety net 2, the front safety net 2 being mounted on the main frame 1. The front safety net 2 includes a first side 21, which is inclined and hinged to the main frame 1; the front safety net 2 can rotate around the hinged position of the first side 21 to open laterally.

[0038] In this application, the front guard net 2 is hinged to the main frame 1 via the first side 21 on the side, so that the front guard net 2 can be opened to the side and outward. On the one hand, it is convenient to open, and on the other hand, it is convenient to open the front guard net 2 at a large angle, which facilitates operations such as de-icing and cleaning of the cab glass protected by the guard net. The working space is large, the operation is convenient, and the work efficiency is high.

[0039] In some embodiments, the first side 21 is inclined, such as Figure 2 In the middle, the front protective net 2 has a trapezoidal structure, and the first side 21 is... Figure 2 The left side of the front protective net 2, which has a trapezoidal structure, is also the first side 21, and is in an inclined state.

[0040] In this application, the first side 21 is inclined and hinged to the main frame 1, so that the front guard net 2 opens laterally when it is opened. Compared with the existing loader cab guard net related technology, the guard net opens upward, downward or left and right. The front guard net 2 that opens to one side has a large opening angle, and after opening, the working space is large, the operation is convenient and the operation efficiency is high. In addition, the front guard net 2 that opens to one side.

[0041] In some embodiments, a hinge 6 is fixedly installed on the first side 21, and the hinge 6 is also fixedly installed on the main frame 1. The hinge 6 enables the front guard 2 to be hinged to the main frame 1, realizes the installation and connection of the front guard 2 on the main frame 1, and ensures that the front guard 2 can be opened laterally outward.

[0042] In some embodiments, the front guard 2 further includes a second side 22 on which a lock 4 is mounted, the lock 4 locking the front guard 2 to the main frame 1. The lock 4 securely connects the front guard 2 to the main frame 1 when the front guard 2 is closed.

[0043] In some embodiments, the second side 22 may be the opposite side of the first side 21, or it may be an adjacent side of the first side door, or a side separated from the first side door, etc. See also Figure 2 The front guardrail 2 is trapezoidal in shape, and the second side 22 can be any one of the three remaining sides excluding the first side 21.

[0044] In some embodiments, the second side 22 is the opposite side of the first side 21, which better enables the front guard net 2 to be locked onto the main frame 1.

[0045] In some embodiments, the lock 4 includes a locking pin 41 and a lock body 42. The locking pin 41 is fixedly installed on the second side 22, and the lock body 42 is fixedly installed on the main frame 1. The position of the lock body 42 is adapted to the position of the locking pin 41. The locking pin 41 is located on the second side 22, which facilitates locking with the lock body 42 on the main frame 1. Simultaneously, it avoids significant vibration or shaking of the lock body 42 during the opening or closing of the front guardrail 2, extending the service life of the lock body 42 and thus extending the service life of the lock 4. Furthermore, installing the lock body 42 on the main frame 1 also facilitates its installation and fixation.

[0046] In some embodiments, the loader cab safety net also includes a limiting mechanism 3 for limiting the angle at which the front safety net 2 opens laterally.

[0047] The limiting mechanism 3 includes a first end 32 and a second end 33. The first end 32 is installed on the front guard net 2, and the second end 33 is installed on the main frame 1. After the front guard net 2 is opened, the limiting mechanism 3 keeps the distance between the first end 32 and the second end 33 fixed.

[0048] Based on the aforementioned front guard net 2, which includes a first side 21 that is inclined, and is hinged to the main frame 1, it can be seen that the front guard net 2 has a hinge axis after being hinged to the main frame 1. The hinge axis is parallel to the first side 21 and is inclined. That is, the hinge axis is inclined, and the hinge axis has an angle with the vertical direction. This makes it difficult for the side-opening front guard net 2 to maintain a stable open state, and it is very easy to cause shaking, swinging, or accidental closing. Therefore, a limiting mechanism 3 is set here to limit the side-opening state and angle of the front guard net 2, ensuring that the front guard net 2 maintains a stable open state after opening.

[0049] After the front protective net 2 is opened, the limiting mechanism 3 keeps the distance between the first end 32 and the second end 33 fixed. This is a necessary state for the limiting mechanism 3 to keep the front protective net in the open state. The limiting mechanism 3 keeps the front protective net 2 in the open state by keeping the distance between the first end 32 and the second end 33 fixed.

[0050] In some embodiments, the limiting mechanism 3 includes a gas spring 31, with two ends of the gas spring 31 being a first end 32 and a second end 33, respectively. The first end 32 is rotatably connected to the front guard net 2, and the second end 33 is rotatably connected to the main frame 1.

[0051] The gas spring 31 utilizes a combination of compressed gas energy storage and damping medium energy dissipation to achieve linear motion. The gas spring 31 contracts when the front guard 2 is closed and extends when the front guard 2 is open. It has a simple structure, is easy to install, and does not affect the closing and opening of the front guard 2. When the front guard 2 is open, the gas spring 31 remains extended due to the damping medium, thus keeping the front guard 2 in the open state.

[0052] The first end 32 and the second end 33 of the front guard net 2 are rotatably connected to the front guard net 2 and the main frame 1, respectively, to prevent the gas spring 31 from being over-positioned, to prevent the gas spring 31 and the front guard net 2 from interfering with the main frame 1, to ensure that the state and position of the gas spring 31 change with the opening and closing of the front guard net 2, to facilitate the opening and closing of the front guard net 2, and to facilitate keeping the front guard net 2 in a stable open state.

[0053] The limiting mechanism 3 uses a gas spring 31. When the front guard 2 needs to be opened, the lock 4 is opened, and the front guard 2 will automatically open outward under the action of the gas spring 31. When the front guard 2 needs to be closed, an external force is applied to overcome the elasticity of the gas spring 31, and the front guard 2 is closed. Then, the lock is tightened to ensure that the front guard 2 remains closed.

[0054] In some embodiments, the front guard net 2 includes a lower side edge 23, with a first end 32 connected to the lower side edge 23; the main frame 1 includes a lower side edge 11, with a second end 33 connected to the lower side edge 11. That is, the limiting mechanism 3 is connected to the lower edge of the front guard net 2. Lowering the installation position of the limiting mechanism 3 makes it easier for the force application point to be closer to the limiting mechanism 3 when the front guard net 2 is closed, allowing for the application of a smaller force to overcome the elasticity of the gas spring 31 and close the front guard net 2. Additionally, the limiting mechanism 3 is connected to the lower edge of the front guard net 2, see reference... Figure 2 The supporting force applied by the limiting structure can provide a certain support for the front guard net 2, further ensuring that the front guard net 2 is in a stable open state.

[0055] In some embodiments, the first end 32 is connected to a fisheye connector 34, and the second end 33 is connected to a fisheye connector 35. The fisheye connector 34 is installed with the front guard net 2, and the fisheye connector 35 is installed with the main frame 1.

[0056] The fisheye joint allows for combined axial, radial, and moment loads, reducing the precision constraints of structural assembly, facilitating the opening and closing of the front guard net 2, avoiding interference between the limiting mechanism 3 and the front guard net 2, and avoiding interference between the limiting mechanism 3 and the main frame 1.

[0057] In the above embodiments, fisheye connector 34 and fisheye connector 35 are used to ensure that the limiting mechanism 3 is installed on the first side in an inclined state, to ensure that the limiting mechanism 3 works normally, and that the limiting mechanism 3 can ensure that the front guard net is in a stable open state.

[0058] In some embodiments, the loader cab safety net also includes a vibration damping mechanism 5, which includes a vibration damping pad 52 fixedly mounted on the main frame 1. After the front safety net 2 is closed, at least part of the front safety net 2 contacts the vibration damping pad 52.

[0059] The vibration damping pad 52 dampens the vibration of the closed front guard 2, preventing the front guard 2 from colliding with the main frame 1. Specifically, when the front guard 2 is closed, the curved plate 51 on the front guard 2 contacts the vibration damping pad 52, thereby buffering and damping the front guard 2.

[0060] The second objective of this utility model is to disclose a loader that includes the aforementioned protective netting in the loader cab. The use of this protective netting in the loader cab makes the cab glass easy to clean and facilitates de-icing operations, thereby improving work efficiency.

[0061] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
