Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation grilles in bulldozers, in particular to a ventilation grille installation structure on a bulldozer. Background Art

[0002] The ventilation grille on a bulldozer is an important component in the bulldozer structure. Although the specific design and location may vary depending on the model and brand of bulldozer, the main functions of the ventilation grille usually include ventilation and heat dissipation, reducing wind resistance, and protecting internal mechanical components.

[0003] In order to keep the bulldozer in normal working condition and extend its service life, the whole machine needs to be maintained regularly. At present, the bulldozer ventilation grille is fixed with bolts, which is not convenient to disassemble during the maintenance of the whole machine, affecting work efficiency. In addition, the current ventilation grilles are mostly installed upright. At the same height, the inclined ventilation grilles have a larger heat dissipation area and the heat dissipation efficiency of the radiator is higher. In addition, the current ventilation grille structure is mostly rigidly connected, and the bolts are likely to loosen after the whole machine has been working for a period of time, thereby generating abnormal noise. Utility Model Content

[0004] In order to solve the technical problem of inconvenient maintenance of ventilation grilles in bulldozers in the background technology, the purpose of the utility model is to provide a ventilation grille installation structure on a bulldozer, which can solve the above problem.

[0005] The technical solution for achieving the purpose of the utility model is: a ventilation grille installation structure on a bulldozer, comprising a ventilation grille, one side of which is mounted on the bulldozer frame through a hinge mechanism, and a portable lock is also provided on the frame near the other side of the ventilation grille for locking the ventilation grille; a buffer is also provided between the ventilation grille and the frame for reducing the force applied to the ventilation grille.

[0006] The ventilation grille in this solution is hinged on one side for easy rotation, and locked on the other side with a portable lock. When disassembly is required, the portable lock can be opened, and the ventilation grille can be rotated around the hinge mechanism. After rotation, routine maintenance operations such as cleaning or replacing gauze can be performed. After maintenance is completed, it can be re-locked with the portable lock, which is simple, convenient and fast to operate. A buffer is also added to the ventilation grille, specifically installed between the ventilation grille and the frame. It can buffer the ventilation grille from bumps or large vibrations during bulldozer operation, solving the problem of ventilation grilles in traditional bulldozers being connected and installed with rigid steel, which are easily loosened due to vibration and stress, and bolts falling off.

[0007] Furthermore, the portable lock includes a locking ring and a handle, one end of the handle being rotatably mounted on the frame, the locking ring being rotatably mounted on the handle, and a locking hook corresponding to the locking ring being mounted on the ventilation grille. Rotation of the handle drives the locking ring toward or away from the locking hook. To lock the ventilation grille, the handle is rotated toward the locking hook. The locking ring, being on the handle, also moves toward the locking hook. After the locking ring is sleeved on the locking hook, the operating handle is rotated away from the locking hook, and the locking ring cooperates with the locking hook to lock the ventilation grille.

[0008] Furthermore, the hinge mechanism includes a welding bracket, an assembly bracket, and a pin. The assembly bracket is fixed to the frame. One end of the assembly bracket is fixed to a shaft seat. The shaft seat is provided with a pin hole. The pin is rotatably mounted in the pin hole. The pin is welded to the welding bracket, and the welding bracket is fixed to one side of the ventilation grille. When the ventilation grille needs to rotate, the welding bracket relies on the rotation of the pin on the shaft seat to achieve this. The rotation structure is simple and easy to implement.

[0009] Furthermore, both ends of the pin shaft have locking holes, and locking pins are installed in the locking holes. The length of the locking pin is greater than the diameter of the pin hole. The locking pin is used to prevent the pin shaft from slipping out of the pin hole during rotation, causing the ventilation grille and the frame to separate and become unable to rotate.

[0010] Furthermore, the buffer comprises a glued component, which is a metal component covered with a rubber material. The glued component is fixed to the ventilation grille and located on the side of the ventilation grille facing the frame. In other words, the glued component relies on the metal component for connection strength, while the rubber material can also provide a buffering effect when subjected to force. For example, a glued component can be formed by coating the outer periphery of a nut with rubber material. During ventilation grille installation, the glued component can cooperate with bolts to secure certain parts, while also relieving the ventilation grille from vibrations by balancing it against the frame.

[0011] Furthermore, the ventilation grille is installed on the frame at an angle of 40°-50° with the bottom of the frame. Compared to installing the ventilation grille vertically on the frame, the angled installation can increase the heat dissipation area and ventilation effect. After testing, the effect is optimal when the ventilation grille is tilted at an angle of approximately 45° with the bottom of the frame.

[0012] Furthermore, at least two wedge-shaped, mating adhesive components are provided at the abutment point between the rear end of the ventilation grille and the frame. Because the ventilation grille is installed at an angle, the rear end of the ventilation grille needs to bear part of its own weight and is subject to greater vibration forces. Therefore, at least two wedge-shaped, mating adhesive components are provided at a corner on one side of the rear end of the ventilation grille, increasing the contact area and allowing for greater stress resistance. The fixing method can be a fixed bolt structure.

[0013] By adopting the above technical solution, the utility model has the following beneficial effects:

[0014] (1) A hinge mechanism is provided on one side of the ventilation grille to facilitate its rotation, and a portable lock is provided on the other side for locking. With this arrangement, when the ventilation grille needs to be maintained, it is only necessary to rotate the ventilation grille;

[0015] (2) A buffer is provided between the ventilation grille and the frame to reduce the stress on the ventilation grille and prevent the structure from becoming loose due to excessive stress, such as the falling off of the fixing bolts.

[0016] (3) The buffer is a composite part formed by wrapping a metal part with a rubber material. It has a certain degree of rigidity while having a buffering effect. For example, a circular composite part is formed by wrapping a rubber material around the outer periphery of a nut.

[0017] (4) The ventilation grille is tilted at 40°-50°, which provides a larger heat dissipation area and ventilation effect;

[0018] (5) Two matching wedge-shaped adhesive parts are set at the tail of the ventilation grille. The contact area can withstand greater stress than that of the circular adhesive parts, and can support the weight of the ventilation grille when it is tilted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] Example:

[0029] like Figure 1-Figure 3 As shown, this embodiment provides a ventilation grille installation structure on a bulldozer, including a ventilation grille 1, one side of which is mounted on the bulldozer frame 19 via a hinge mechanism 2. A portable lock 3 is also provided on the frame 19 near the other side of the ventilation grille 1 for locking the ventilation grille 1; a buffer is also provided between the ventilation grille 1 and the frame 19 for reducing the force on the ventilation grille 1. The ventilation grille 1 in this solution is easy to rotate by a hinged structure on one side, and is locked by a portable lock 3 on the other side. When disassembly is required, the portable lock 3 can be opened, and the ventilation grille 1 rotates around the hinge mechanism 2. After rotation, routine maintenance operations such as cleaning or replacing gauze can be performed. After maintenance is completed, it only needs to be locked again using the portable lock 3. The operation is simple, convenient and fast. A buffer is added to the ventilation grille 1, which is specifically installed between the ventilation grille 1 and the frame 19. It can buffer the force on the ventilation grille 1 when encountering bumps or large vibrations during bulldozer operation, thereby solving the problems that the ventilation grille 1 in traditional bulldozers is connected and installed with rigidity, which is easy to become loose in structure and bolts fall off after being subjected to vibration and force.

[0030] Preferably, the ventilation grille 1 is installed on the frame 19 at an angle of 40°-50° with the bottom 16 of the frame 19. Compared to installing the ventilation grille 1 vertically on the frame 19, the inclined installation can increase the heat dissipation area and ventilation effect. After testing, the effect is best achieved when the ventilation grille 1 is tilted at an angle of about 45° with the bottom 16 of the frame 19.

[0031] Figure 4-Figure 5As shown, the buffering member comprises a glued member 15, which is a metal member covered with a rubber material. This glued member 15 is fixed to the ventilation grille 1 and located on the side of the ventilation grille 1 facing the frame 19. In other words, the glued member 15 relies on the metal member for connection strength, while the rubber material can also provide a buffering effect when subjected to stress. For example, the glued member 15 can be formed by coating the outer periphery of a nut with rubber material. During the installation of the ventilation grille 1, the glued member 15 can cooperate with the fixing bolts 20 to secure certain parts, while also relieving the ventilation grille 1 from stress when subjected to vibration, such as by facing the frame 19.

[0032] Preferably, at least two wedge-shaped, mating adhesive components 18 are provided at the junction of the tail portion 17 of the ventilation grille and the frame 19. Since the ventilation grille 1 is installed at an angle, the tail portion 17 of the ventilation grille needs to bear part of its own weight and is subject to greater vibration forces. Therefore, at least two wedge-shaped, mating adhesive components 18 are provided at a corner on one side of the tail portion 17 of the ventilation grille. This increases the contact area and can withstand greater stress. The fixing method can be a bolt fixing structure.

[0033] like Figure 6 As shown, the hinge mechanism 2 includes a welding bracket 8, an assembly bracket 9, and a pin 10. The assembly bracket 9 is fixed to the frame 19. A shaft seat 11 is fixed to one end of the assembly bracket 9. The shaft seat 11 is provided with a pin hole 12. The pin 10 is rotatably mounted in the pin hole 12. The pin 10 is welded to the welding bracket 8, and the welding bracket 8 is fixed to one side of the ventilation grille 1. When the ventilation grille 1 needs to rotate, the welding bracket 8 relies on the rotation of the pin 10 on the shaft seat 11 to achieve this. The rotation structure is simple and easy to implement. The pin 10 has locking holes 13 at both ends. The locking pin 14 is installed in the locking hole 13. The length of the locking pin 14 is greater than the diameter of the pin hole 12. The locking pin 14 is used to prevent the pin 10 from sliding out of the pin hole 12 during rotation, causing the ventilation grille 1 to separate from the frame 19 and become unable to rotate.

[0034] like Figure 7 As shown, the portable lock 3 includes a locking ring 5 and a handle 6. One end of the handle 6 is rotatably mounted on the frame 19. The locking ring 5 is rotatably mounted on the handle 6. A locking hook 7 corresponding to the locking ring 5 is mounted on the ventilation grille 1. The rotation of the handle 6 drives the locking ring 5 toward or away from the locking hook 7. When the ventilation grille 1 needs to be locked, the handle 6 is rotated toward the locking hook 7. The locking ring 5 is on the handle 6 and therefore moves toward the locking hook 7. After the locking ring 5 is sleeved on the locking hook 7, the operating handle 6 is rotated away from the locking hook 7. The locking ring 5 will cooperate with the locking hook 7 to lock the ventilation grille 1.

[0035] Working principle: First, the ventilation grille 1 is rotatably mounted on the frame 19 by means of a hinge mechanism 2, which makes it convenient to open and maintain, and is locked by means of the portable lock 3 after closing; secondly, a bonding part 15 is added between the ventilation grille 1 and the frame 19, which not only acts as a buffer after being subjected to stress, but is also made of a metal part coated with rubber material, has a certain rigid strength, can be made with conventional nuts, and can also play a fixing role.

[0036] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
