Description

Technical Field

[0001] The utility model relates to the field of engineering machinery, in particular to an integrated flip-type machine cover of engineering machinery. Background Art

[0002] Loaders are engineering machinery widely used in earthwork construction. A bucket is provided on the front side of the loader, and the bucket is connected to the loader through a boom and an arm. A boom cylinder for controlling the movement of the arm is installed on the upper part of the boom. In addition, a boom cylinder for controlling the movement of the boom is also installed on the excavator. The boom cylinder is supplied with oil through the boom lifting oil circuit, and the boom lifting and falling are controlled by the boom cylinder; the movement of the bucket is controlled by the rocker arm cylinder, which is supplied with oil through the bucket retracting oil circuit, and the rocker arm rotation is controlled by the rocker arm cylinder, driving the bucket to complete the retracting and digging actions.

[0003] At present, most of the existing engineering machinery hoods are multi-segment welded structures that are simple to process and manufacture. Most of the components of this structure are not beautiful, have poor manufacturing accuracy, and are inconvenient to replace and repair, and need to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated flip-type hood for engineering machinery with beautiful structure and convenient maintenance in view of the above problems.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses an integrated flip-up hood for engineering machinery, which has the following structural features: it includes a frame, a cover and a hood are installed on the upper part of the frame, the hood is located on the rear side of the cover, the rear part of the hood is hinged to the frame, a gas spring is installed on the frame for supporting the hood after the hood is opened, the upper part of the gas spring is hinged to the hood, and a lock is installed on the hood for locking the hood after the hood is closed.

[0006] The hood is connected to the frame by a hinge, so that the hood can be opened and closed easily. This design not only simplifies the operation process and improves work efficiency, but also makes maintenance and overhaul easier. The introduction of the gas spring provides a stable support for the hood. After the hood is opened, the gas spring can effectively support the hood to prevent it from accidentally falling or shaking, thereby ensuring the safety of operation. At the same time, the setting of the gas spring also enhances the durability of the hood and prolongs its service life. After the hood is closed, it is locked by the rear lower lock to prevent the hood from floating during driving and has an anti-theft effect.

[0007] The rear end of the frame is equipped with a counterweight, which is buckled on the top of the counterweight after the hood is closed. The counterweight installed at the rear end of the frame not only increases the stability of the entire machine, but also buckles on the top of the counterweight after the hood is closed, playing a balancing role. This design helps reduce the shaking of the hood during the closing process and improves the stability of the operation.

[0008] There are two gas springs, which are spaced apart on the left and right. The limit mechanism and soft limit provide double protection. The limit mechanism on the gas spring can maintain the length of the gas spring after the hood is opened to prevent it from being over-stretched or compressed, thereby protecting the performance and service life of the gas spring.

[0009] Preferably, at least one gas spring is provided with a limiting mechanism for maintaining the length of the gas spring after the hood is opened.

[0010] A hinge for connecting the hood is installed on the frame. The hinge is used to connect the hood and the frame so that the hood can be flipped along the hinge.

[0011] The hood is equipped with a soft limiter that presses against the counterweight when the hood is closed. The soft limiter on the hood presses against the counterweight when the hood is closed, playing a role of buffering and limiting, further enhancing the stability and safety of the hood.

[0012] There are multiple soft limits, which are located on the left and right sides of the lower part of the hood. The soft limits can press against the counterweight when the hood is closed, playing a role of buffering and limiting, avoiding hard collision between the hood and the counterweight, reducing the wear of mechanical parts, and improving the stability of the hood when it is closed, which can more comprehensively protect the hood and the counterweight.

[0013] The soft limit is a rubber pad. The rubber pad is used as the soft limit material, which has good buffering performance and wear resistance.

[0014] The lock buckle is installed on the lower rear side of the hood, and a lock ring for matching the lock buckle is installed on the counterweight. The lock buckle installed on the hood cooperates with the lock ring on the counterweight to achieve a secure lock after the hood is closed. This design not only enhances the sealing of the hood and prevents dust and debris from entering the internal components of the machine, but also improves the safety of the entire machine and prevents accidents.

[0015] The front side of the hood is provided with a plug-in plate, which extends forward and is plugged into the inner side of the cover. The plug-in plate design on the front side of the hood enables the plug-in plate to be plugged into the inner side of the cover, thereby enhancing the sealing between the hood and the cover. This design helps prevent external factors such as dust and moisture from entering the internal components of the machine, thereby improving the reliability and durability of the entire machine.

[0016] In summary, the beneficial effects of the utility model are: 1. The hood is flipped by a hinge, one end of the hinge is fixed on the frame, and the other end is fixed on the hood; 2. When maintenance is needed, the hood is flipped and supported by two gas springs, one of which is provided with a limiting mechanism to prevent the hood from falling and injuring people; 3. Soft limits are respectively provided on the left and right lower parts of the hood. After the hood is closed, the soft limit contacts the support surface of the frame and is stably fixed on the frame together with the two hinge points. After being fully closed, the hood is locked by the rear lower lock to prevent the hood from floating during driving and to prevent theft; 4. The front end of the hood is designed with a recessed structure, which is embedded in the front end cover after being fully fitted to make it fit perfectly and ensure sealing.
