Description

Technical Field

[0001] The utility model relates to the field of mining vehicles, in particular to a mining vehicle cab support mechanism. Background Art

[0002] Mining trucks are off-road vehicles primarily used in mines and construction. They are more durable and carry more payload than standard trucks. Structurally, mining trucks appear similar to regular dump trucks, seemingly just a bit larger. However, their design philosophy is fundamentally different. While standard dump trucks are designed for road transport, mining trucks are designed for mine construction operations. Therefore, both the entire vehicle and its components are designed with mining environments in mind.

[0003] The cab is the control part of the mining vehicle and is installed on the front side of the vehicle body. Corresponding support mechanisms are installed on both sides of the vehicle body to connect and support the cab. However, because corresponding circuit pipes and water pipes need to be installed in the cab to connect and control the vehicle body, corresponding through-holes need to be opened on the support mechanisms to pass through and fix the pipes. However, the gravity of the cab acts on the support mechanism, and the stress concentration after the through-holes are opened can easily cause cracks at the through-hole position, thereby affecting the bearing capacity and rigidity of the support mechanism. If the driver does not discover it in time, accidents may easily occur over time.

[0004] Therefore, the research purpose of the present invention is to design a mining vehicle cab support mechanism that can effectively alleviate stress concentration at the through hole to ensure load-bearing capacity and rigidity, and can clearly display and promote auxiliary driving personnel to promptly discover cracks at the through hole and make timely repairs or replacements. Utility Model Content

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a mining vehicle cab support mechanism, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A mining vehicle cab support mechanism, comprising:

[0008] At least one support assembly, the support assembly comprising two spaced apart support members arranged side by side, each of the support members being provided with at least one through hole for passing a circuit pipe and / or a water pipe of the mining vehicle;

[0009] The connecting mechanism includes an inner sleeve that is inserted into the through hole of the support member, and the two ends of the inner sleeve protrude from the outer side surfaces of the support members on both sides of the support assembly. An outer sleeve 4 is fixedly installed between the two support members and is sleeved on the outside of the inner sleeve 3;

[0010] A detection mechanism is installed at the through hole of the support member and is used to detect cracking of the through hole. The connections between the inner sleeve and the outer sleeve and the support member are fixedly connected by welding. The positive pressure in the sealed cavity formed by the inner and outer sleeves being spaced apart is filled with corresponding shock-absorbing materials. The detection mechanism includes a pressure gauge installed on the outer sleeve and used to check the sealing performance of the sealed cavity.

[0011] The supporting assembly is located on the top of the two supporting members and is fixedly mounted with corresponding connecting plates by welding or integral molding.

[0012] The support member is located at the bottom of the side connected to the mining vehicle body and is provided with a corresponding right-angle chamfer. The right-angle chamfer of the support member is fixed with an inverted L-shaped connecting plate. The connecting plate is used to connect the two support members on the support assembly and install the support mechanism on the mining vehicle body.

[0013] A one-way valve connected to the sealing cavity is installed on the outer sleeve.

[0014] The sealed cavity is filled with a damping fluid or a shock-absorbing fluid by positive pressure injection.

[0015] The sealing cavity is filled with one or a mixture of damping materials selected from the group consisting of damping medium, rubber particles, sponge particles, foam particles, and latex particles, and air is filled at a positive pressure in the gaps between the damping materials.

[0016] The detection end of the pressure gauge extends downward into the sealed cavity, and a corresponding protective cover is installed on the outside of the detection end. The protective cover is fixedly installed on the inner wall of the outer sleeve, and the surface of the protective cover is evenly distributed with air holes with an aperture smaller than the particle size of the shock-absorbing material.

[0017] The support components are arranged at intervals in front and back, and corresponding connecting rods are connected at intervals on the upper sides of two adjacent support components. Each support component is provided with a corresponding inner sleeve or an inner sleeve is inserted to connect all support components.

[0018] Advantages of this utility model:

[0019] 1) The utility model effectively alleviates the stress concentration at the through hole to ensure the load-bearing capacity and rigidity of the support mechanism by adding a connecting mechanism and a detecting mechanism at the through hole of the support mechanism, and can clearly display and promote the auxiliary driver to promptly discover the cracks at the through hole and make timely repairs or replacements.

[0020] 2) The utility model is composed of at least two support members, and a connecting mechanism composed of an inner sleeve and an outer sleeve arranged inside and outside is installed at the through hole of the support mechanism. The inner sleeve is used to weld and connect all the support members, and the outer sleeve is used to connect two adjacent support members. It not only provides a guide installation for the pipeline, but also improves the stability and rigidity of the support member connection. The outer sleeve is arranged with inner and outer intervals to further improve the stability and rigidity, and a corresponding sealed cavity is formed to facilitate the installation of the detection mechanism.

[0021] 3) The utility model fills the sealed cavity with corresponding shock-absorbing materials under positive pressure, and then fills the gap with air after a mixture of damping liquid or shock-absorbing liquid or one or more of damping medium, rubber particles, sponge particles, foam particles, and latex particles. The friction energy consumption and / or elastic deformation of the shock-absorbing particles are used to absorb and disperse part of the vibration energy, further eliminating the stress at the through hole, thereby avoiding the adverse effects of vibration on the through hole.

[0022] A pressure gauge extending into the sealed cavity is installed on the outer sleeve. Changes in the pressure gauge's readings can be used to determine if the through-hole is cracked. Even if this change indicates a seal failure caused by welding problems, it is sufficient to allow the driver to promptly detect cracks in the through-hole, ensuring safety. Furthermore, air is filled into the sealed cavity when the shock-absorbing particles are introduced to maintain a positive pressure environment. A protective shield is installed on the outside of the pressure gauge to prevent particles from sticking and squeezing, which could affect the pressure gauge reading, enhancing practicality.

The sealing cavity 5 formed by the inner sleeve 3 and the outer sleeve 4 are spaced apart inside and outside and is filled with corresponding shock-absorbing materials 7 under positive pressure. The detection mechanism includes a pressure gauge 6 installed on the outer sleeve 4 and used to check the sealing performance of the sealing cavity 5.

[0034] The utility model effectively alleviates the stress concentration at the through hole 2 to ensure the bearing capacity and rigidity of the support mechanism by adding a connecting mechanism and a detecting mechanism at the through hole 2 of the support mechanism, and can clearly display and promote the auxiliary driver to promptly discover the cracking of the through hole 2 and make timely repairs or replacements.

[0035] The utility model is composed of at least two support members 1, and a connecting mechanism composed of an inner sleeve 3 and an outer sleeve 4 arranged inside and outside is installed at the through hole 2 of the support mechanism. The inner sleeve 3 is used to weld and connect all the support members 1, and the outer sleeve 4 is used to connect two adjacent support members 1, which not only provides a guide installation for the pipeline, but also improves the stability and rigidity of the connection of the support members 1, and further improves the stability and rigidity by using the outer sleeve 4 to be arranged at intervals inside and outside, and forms a corresponding sealed cavity 5 to facilitate the installation of the detection mechanism.
