Description

Technical Field

[0001] The utility model relates to the technical field of hood limiting, in particular to a hood limiting device for an excavator. Background Art

[0002] The excavator engine hood plays a vital role in the excavator. Excavators usually work in relatively harsh environments. The engine hood can effectively prevent external impurities, such as dust, sand, etc. from entering the engine, protecting the engine from damage and playing a role in protecting the engine.

[0003] The prior art provides an excavator engine hood with a limiting mechanism (notification number CN210263209U). The utility model includes a hood lock, a sealing strip, a gas spring, a hood, a positioning column, and a locking nut. The right end of the hood is hinged to the end face of the engine rear beam through a hinge, and the inner side of the hood is connected to a mounting seat and is connected to the gas spring through the mounting seat... In the closed state, the top of the positioning column contacts the bottom of the limiting plate, and the sealing strip connected to the engine front beam and the engine rear beam is in a semi-compressed state. The height of the positioning column is adjusted by adjusting the locking nut.

[0004] The above-mentioned excavator engine hood with a limiting mechanism still has some problems in the actual operation process. For example, when limiting and fixing the excavator hood, it is necessary to operate the hood lock to fix the excavator hood, and the excavator hood cannot be fixed more conveniently. The practicality is poor. In order to facilitate the limiting and fixing of the excavator hood, we need to propose an excavator hood limiting device. Utility Model Content

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] A hood limiting device for an excavator comprises a fixing member 1 and a shell 2, wherein the shell 2 is movably mounted on the fixing member 1, a fixing plate 4 is fixedly connected to the side of the fixing member 1, a first sliding hole 5 and a second sliding hole 6 are provided in the fixing plate 4, a push spring 11 is provided in the first sliding hole 5 and the second sliding hole 6, a first positioning seat 9 is fixedly installed at the end of the push spring 11 in the first sliding hole 5, a second positioning seat 12 is fixedly installed at the end of the push spring 11 in the second sliding hole 6, a ball 18 is provided at one end of the first positioning seat 9 and the second positioning seat 12, an insert block 14 is fixedly connected to the side of the shell 2, a first inclined portion 15 is provided at the lower end of the insert block 14, a positioning socket 19 is provided in the insert block 14, and one end of the first positioning seat 9 and the second positioning seat 12 are both plugged into the positioning socket 19;

[0026] A first guide rod 7 is fixedly connected in the first sliding hole 5, and a first positioning seat 9 is slidably mounted on the first guide rod 7;

[0027] In this embodiment, the first positioning seat 9 is slidably mounted on the first guide rod 7, so that the first guide rod 7 can support and position the first positioning seat 9;

[0028] A second guide rod 8 is fixedly connected in the second sliding hole 6, a second positioning seat 12 is slidably mounted on the second guide rod 8, and a push spring 11 is sleeved on the first guide rod 7 and the second guide rod 8;

[0029] It is worth mentioning that the second positioning seat 12 is slidably mounted on the second guide rod 8, so that the second guide rod 8 can support and position the second positioning seat 12;

[0030] Both sides of the insert block 14 are fixedly connected with a reinforcement seat 16, and both sides of the reinforcement seat 16 are open. One end of the first positioning seat 9 and the second positioning seat 12 are inserted into the reinforcement seat 16;

[0031] It is worth noting that the reinforcing seat 16 can improve the positioning effect of the first positioning seat 9 and the second positioning seat 12;

[0032] A second inclined portion 17 is formed on the reinforcing seat 16;

[0033] It is worth noting that the rolling of the ball 18 is prevented by the second inclined portion 17;

[0034] A handle 10 is fixedly mounted on the upper end of the first positioning seat 9 and the second positioning seat 12;

[0035] It is worth noting that the first positioning seat 9 and the second positioning seat 12 can be easily opened by the handle 10;

[0036] A gas spring 3 is arranged in the fixing member 1, and the telescopic end of the gas spring 3 is movably mounted on the inner bottom of the housing 2;

[0037] It is worth mentioning that the housing 2 can be supported by the gas spring 3;

[0038] The fixing plate 4 is provided with a through hole 13, and the insert block 14 is inserted into the through hole 13;

[0039] In specific use, when the hood is closed, the housing 2 is pressed down so that the plug block 14 passes through the through hole 13 and approaches the first positioning seat 9 and the second positioning seat 12. When the first inclined portion 15 of the plug block 14 contacts the ball 18, the ball 18 can push the first positioning seat 9 and the second positioning seat 12, so that the first positioning seat 9 and the second positioning seat 12 can move away from each other due to the rolling of the ball 18 on the first inclined portion 15. After the first positioning seat 9 and the second positioning seat 12 are inserted and rolled, when the ball 18 is aligned with the positioning insertion hole 19, it can be inserted into the plug block 14 under the push of the push spring 11, thereby achieving the fixation of the plug block 14, and then it is convenient to limit and fix the excavator hood;

[0040] When the hood needs to be opened, the handle 10 can be used to push the first positioning seat 9 and the second positioning seat 12 to slide on the first guide rod 7 and the second guide rod 8, so that the first positioning seat 9 and the second positioning seat 12 are moved out of the positioning socket 19, and the force of the first positioning seat 9 and the second positioning seat 12 fixing the plug 14 disappears. At this time, the shell 2 can be opened.
