Description

Technical Field

[0001] The utility model relates to the technical field of mining vehicles, in particular to a locking device for a mining vehicle hood lock. Background Art

[0002] Mining vehicles are off-road vehicles, mainly used in mines and engineering. They are more durable and can carry more than general trucks. Structurally, there seems to be no big difference between mining vehicles and ordinary dump trucks, except that they are just a little "bigger". In fact, mining vehicles are essentially different from ordinary dump trucks in terms of design concept. Ordinary dump trucks are used to meet the needs of road transportation, while mining vehicles are used to meet the needs of mine construction. Therefore, the entire vehicle and parts used in mining vehicles take into account the mining operating environment and are designed and manufactured for such users. The working environment of mining vehicles is complex. When the vehicle is driving on a bumpy road, the vibration is transmitted to the hood lock, which will be impacted, causing the relative position of the locking mechanism to shift, shortening its service life, and in severe cases, it will break, posing a safety hazard.

[0003] The hood lock generally consists of two parts, one is a movable part installed on the upper hood, and the other is a fixed part installed on the vehicle body. The movable part and the fixed part are respectively provided with a hanging ring and a hook. When installing the hood lock, the hanging ring and the hook can also be exchanged. When closing the upper hood, the hanging ring is placed on the hook, and then the movable part is operated to lock the two together, thereby fixing the upper hood.

[0004] The existing hood lock cannot adjust the locking force. During the operation of the vehicle, the upper hood shakes with the bumps of the vehicle body. During this process, the movable part and the fixed part are constantly pulled, which increases the failure rate of the upper hood lock and makes the hood lock prone to damage. Utility Model Content

[0005] In view of the defects in the prior art, the utility model provides a locking device for a mining vehicle hood lock to solve the problem that the hood of the mining vehicle is currently locked on a bumpy road section, the hood lock is easily damaged after the vehicle body is bumped, and the failure rate is high.

[0006] The utility model provides a locking device for a mining vehicle hood, comprising:

[0007] Upper fixing bracket;

[0008] A lower mounting bracket is arranged in cooperation with the upper fixing bracket;

[0009] A locking piece, which switches between an unlocked state and a locked state, one end of the locking piece is hinged to the upper fixed bracket, and the other end of the locking piece is flexibly abutted against the lower mounting bracket in the locked state, otherwise the locking piece is in an unlocked state.

[0010] As can be seen from the above technical solution, a locking device for the hood lock of a mining vehicle provided by the present utility model can eliminate the influence of vibration on the hood lock through a locking member that is in flexible contact with the lower mounting bracket, reduce the failure rate of the hood lock, and improve the safety of the whole vehicle.

[0011] Optionally, the lower mounting bracket includes a mounting section and a limiting section, the mounting section and the limiting section are perpendicular to each other, and a limiting groove is formed on the limiting section.

[0012] Optionally, the locking member includes a hinged section, a connecting section, and an abutting section that are connected in sequence. The hinged section is hinged to the upper fixing bracket, and when the locking member is in the locked state, the abutting section is arranged in the limiting groove in a matching manner.

[0013] Optionally, a reinforcing member is arranged on the inner side of the connecting section. When the locking member is in the locked state, the reinforcing member abuts against the mounting surface of the lower mounting bracket.

[0014] Optionally, the abutting section is a flexible sphere.

[0015] Optionally, a handle section is further connected to the abutting section.

[0016] Adopting the above technical solution, the present application has the following technical effects:

[0017] Through the locking member that is in flexible contact with the lower mounting bracket in the present utility model, when the vehicle is driving on a bumpy road section, the vibration is transmitted to the hood lock, and the locking member can offset a certain impact.

[0027] As Figure 1 shown, this embodiment provides a locking device for the hood lock of a mining vehicle, including an upper fixing bracket 1, a lower mounting bracket 2 and a locking member 3. The lower mounting bracket 2 and the upper fixing bracket 1 are cooperatively arranged; the locking member 3 switches between an unlocked state and a locked state. One end of the locking member 3 is hinged to the upper fixing bracket 1, and the other end of the locking member 3 is in flexible abutment with the lower mounting bracket 2 in the locked state, otherwise the locking member 3 is in the unlocked state. Based on this, through the locking member 3 that is in flexible abutment with the lower mounting bracket 2, the influence of vibration on the hood lock can be eliminated, the failure rate of the hood lock can be reduced, and the safety of the whole vehicle can be improved.

[0028] See Figure 1 , the lower mounting bracket 2 includes a mounting section 21 and a limiting section 22. The mounting section 21 and the limiting section 22 are perpendicularly arranged, and a limiting groove 221 is formed on the limiting section 22.

[0029] Optionally, the locking member 3 includes a hinge section 31, a connecting section 32 and an abutting section 33 that are connected in sequence. The hinge section 31 is hinged to the upper fixing bracket 1, and when the locking member 3 is in the locked state, the abutting section 33 is cooperatively arranged in the limiting groove 221.

[0030] As Figure 2As shown, a convex section 11 is formed in the middle area of the upper fixing bracket 1. There is a height difference between the convex section 11 and both ends. The hinged section 31 is arranged in cooperation with the convex section 11, and the connection between the hinged section 31 and the convex section 11 is realized through a pin shaft.

[0031] Optionally, the locking member 3 includes a hinged section 31, a connecting section 32, and an abutting section 33 connected in sequence. The hinged section 31 is hinged to the upper fixing bracket 1. When the locking member 3 is in the locked state, the reinforcing member abuts against the mounting surface of the lower mounting bracket 2.

[0032] Specifically, the abutting section 33 is a flexible sphere. When the locking member 3 is in the locked state, the abutting section 33 abuts against the mounting surface of the lower mounting bracket 2. When the vehicle is overly bumpy, excessive contact may occur between the locking member 3 and the lower mounting bracket 2, resulting in excessive pressure on the abutting section 33 and the limiting groove 221, making the abutting section 33 prone to breakage and affecting the overall reliability of the hood lock locking device.

[0033] As Figure 3 shown, a reinforcing member 34 is arranged on the inner side of the connecting section 32. When the locking member 3 is in the locked state, the reinforcing member 34 abuts against the mounting surface of the lower mounting bracket 2.

[0034] Referring to Figure 3 , a handle section 35 is also connected to the abutting section 33. When it is necessary to open the hood, it is convenient to switch the locking member 3 between the unlocked state and the locked state through the handle section 35.

[0035] In the present utility model, through the locking member 3 that is flexibly abutted against the lower mounting bracket 2, when the vehicle is driving on a bumpy road section, the vibration is transmitted to the hood lock, and the locking member 3 can offset a certain impact. Compared with the traditional mechanical spring structure, it is not easy to be damaged, and the service life is improved.

[0036] In the description of the present utility model, a large number of specific details are illustrated. However, it can be understood that the embodiments of the present utility model can be practiced without these specific details. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this specification.

[0037] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model, and they should all be covered by the scope of the claims and the specification of the present utility model.
