Description

Technical Field

[0001] The utility model relates to the field of tunnel construction equipment, in particular to a tunnel construction crusher. Background Art

[0002] Tunnels, as a kind of building constructed underground, underwater or inside a mountain, mainly serve the laying of railways or the construction of roads for the passage of motor vehicles. Among them, tunnels that cross mountains or hills to shorten the distance and avoid steep slopes are called mountain tunnels. During the construction of mountain tunnels, a large number of large stones are often piled up inside the tunnel. In order to efficiently transport these stones to the outside of the tunnel, crushers become indispensable equipment. Although existing crushers can effectively crush large stones, in some newly built tunnels, water leakage may occur in local areas. This is mainly manifested in water seepage, dripping, leakage on the wall and vault, and water on the road surface. When the dripping water above the wall falls on the crusher, it will not only easily cause the crusher to rust, but also seriously affect the service life and performance of the crusher.

DETAILED DESCRIPTION

[0020] See also Figure 1-5 As shown, an embodiment of the present application provides a technical solution: a tunnel construction crusher, comprising a crusher 1, a height-adjustable column structure 2 is provided on the side of the crusher 1, a length-adjustable frame structure 3 perpendicular to the column structure 2 is provided above the column structure 2, and a tarpaulin 41 is provided on the frame structure 3, and the tarpaulin 41 covers the top of the crusher 1 to prevent rainwater from above from dripping onto the crusher 1.

[0021] The column structure 2 and the frame structure 3 are adjustable to facilitate workers working nearby. Since the height of the workers and the range of raindrops are uncertain, a certain adjustment space is provided.

[0022] The tarpaulin 41 is a common tarpaulin, oilcloth, etc., so that rainwater can directly fall on the crusher 1, which can reduce the rust damage of the crusher 1.

[0023] In a preferred embodiment, the column structure 2 includes a first square tube 21 and a second square tube 22. The second square tube 22 can be inserted into the first square tube 21 and move along the length direction. A first positioning hole 211 is provided on the side wall of the first square tube 21, and a plurality of holes of matching sizes are provided on the second square tube 22. A pin shaft 23 is provided in the first positioning hole 211.

[0024] In the preferred embodiment, the frame structure 3 includes a first frame 31 and a second frame 32. The first frame 31 and the second frame 32 are U-shaped square tube frames. The square tube of the second frame 32 can be inserted into the square tube of the first frame 31 and move along the length direction of the square tube. A second positioning hole 311 is provided on the side of the square tube of the first frame 31, and a hole matching the second positioning hole 311 is provided on the square tube of the second frame 32.

[0025] The adjustment principle of the frame structure 3 is the same as that of the column structure 2, both of which are fixed by inserting a pin 23 into the hole. The method of adjusting the length is to first pull out the pin 23, then pull it out to a certain distance in the second frame 32 or the second square tube 22, and then insert the pin 23 to fix it.

[0026] In the preferred embodiment, a first bearing seat 42 is provided on the first frame 31, a first rotating shaft 43 is provided on the first bearing seat 42, a second bearing seat 44 is provided on the second frame 32, a second rotating shaft 45 is provided on the second bearing seat 44, and the rain cover 41 is wound around the first rotating shaft 43 and the second rotating shaft 45.

[0027] The tarpaulin 41 is fixed on the first rotating shaft 43 and the second rotating shaft 45 in a winding manner, so that when the first frame 31 and the second frame 32 are close to each other, more tarpaulin 41 is wound around the first rotating shaft 43 and the second rotating shaft 45, and when the first frame 31 and the second frame 32 are far from each other, less tarpaulin 41 is wound around the first rotating shaft 43 and the second rotating shaft 45.

[0028] In the preferred solution, a through hole 221 is provided above the second square tube 22, a fourth rotation axis 33 is provided on the side of the first frame 31, and the fourth rotation axis 33 can be inserted into the through hole 221. A latch mechanism 5 is also provided on one side of the second square tube 22, and the latch mechanism 5 includes a body 51 with a T-slot and a latch 52 inserted on the body 51. When the latch 52 is extended, the latch 52 is stuck under the second square tube 22. In this way, the support of the frame structure 3 depends on the support of the latch 52; when the latch 52 is retracted, the frame structure 3 has no support point and will rotate around the column structure 2.

[0029] In this way, the frame structure 3 can rotate around the column structure 2, which makes it convenient to fold up the frame structure 3 when it is not needed to shelter from the rain.

[0030] In a preferred solution, a protrusion 521 is further provided on the latch pin 52 , and the protrusion 521 extends out of the T-slot of the body 51 .

[0031] The protrusion 521 mainly serves to facilitate external pushing.

[0032] In a preferred embodiment, the crusher 1 includes a mounting base 11, on which a shell 12 is provided, the shell 12 includes a feed port 121 and a discharge port 122 arranged below, a pair of crushing rollers 13 are provided in the shell 12, a third rotating shaft 14 for driving the crushing rollers 13 to rotate is provided at the axis of the crushing rollers 13, one side of the third rotating shaft 14 is connected to mutually meshing gears 15, a reducer 16 is connected to the other side of one of the third rotating shafts 14 through a coupling, and one end of the reducer 16 is connected to a motor 17 through a sprocket chain.

[0033] In this way, the motor 17 drives the reducer 16 and finally drives the crushing roller 13, thereby crushing the stone.

[0034] In a preferred embodiment, a belt line 6 is further provided below the crusher 1. The belt line 6 is a relatively well-known belt line of this type.

[0035] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
