Description

Technical Field

[0001] This utility model relates to the field of tunnel repair machine technology, and in particular to a multifunctional tunnel repair machine. Background Technology

[0002] Tunnel repair machines are important loading equipment in coal mines, mainly used in tunnel repair faces with fractured surrounding rock to undertake tunnel repair tasks. Currently, the removal of fractured surrounding rock and the replacement and removal of anchor bolts and anchor mesh are typically done manually. Due to limitations imposed by rock hardness and the degree of fracture in the roof and surrounding rock, manual construction increases the labor intensity of workers and reduces tunneling efficiency. Furthermore, because manual crushing and debris removal are required on unsupported sections, it is difficult to repair some failed anchor bolt and cable holes.

[0003] In the prior art, such as CN210003277U, a roadway working device with a tail-end anchor drilling rig includes a roadway working device body. A conveying mechanism is provided in the middle part of the roadway working device body, and anchor drilling rig mechanisms fixed on the roadway working device body are provided on both sides of the rear end of the conveying mechanism. The anchor drilling rig mechanism includes a horizontally installed anchor drilling rig and a vertically installed anchor drilling rig fixed on the corresponding side of the rear end of the roadway working device body.

[0004] Although the aforementioned roadway repair machine has added the function of a bolt drilling machine, its overall function is still somewhat limited and its application range is small. For example, when it is necessary to flatten the roadway, a separate plate compactor is required to flatten the roadway. If the plate compactor has too high power, it may even cause the risk of collapse.

[0005] Therefore, it is necessary to improve the existing multi-functional roadway repair machine. Utility Model Content

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a multi-functional tunnel repair machine that can controllably flatten the tunnel surface.

[0007] To achieve the above technical effects, the technical solution of this utility model is as follows: a multi-functional roadway repair machine, including a vehicle body, a boom connected to the vehicle body, a bucket disposed on the boom, the bucket being provided with a water leakage hole, and also including a plate compactor assembly, wherein a fixing component for fixing the plate compactor assembly to the bucket is disposed between the plate compactor assembly and the water leakage hole.

[0008] According to one embodiment of the present invention, the plate compactor assembly includes a base and a compaction plate, the base being connected to the bucket and the compaction plate being disposed below the base.

[0009] According to one embodiment of the present invention, the fixing component includes a screw rod disposed on the base, the screw rod passing through the drainage hole, and a nut threadedly connected to the screw rod, and the bucket is clamped between the base and the nut.

[0010] According to one embodiment of the present invention, an inner pad is sandwiched between the nut and the inner wall of the bucket, the inner pad is fitted to the inner wall of the bucket, the nut is in surface contact with the inner pad, and the inner pad has a first through hole for the screw to pass through.

[0011] According to one embodiment of the present invention, an outer pad is sandwiched between the base and the outer wall of the bucket, the outer pad is fitted to the outer wall of the bucket, the base is in surface contact with the outer pad, and the outer pad is provided with a second through hole for the screw to pass through.

[0012] According to one embodiment of the present invention, the ramming plate and the base are rotatably connected by a ball joint.

[0013] According to one embodiment of the present invention, a first hydraulic cylinder is provided between the boom and the bucket, and a first baffle is fixedly provided on the boom, with the first baffle positioned above the first hydraulic cylinder.

[0014] According to one embodiment of the present invention, a pusher is further provided below the vehicle body, and a second hydraulic cylinder is provided between the pusher and the vehicle body.

[0015] According to one embodiment of the present invention, a rotary cylinder is provided between the vehicle body and the boom, and a second baffle is fixedly provided on the vehicle body, the second baffle being disposed above the rotary cylinder.

[0016] The advantages and beneficial effects of this utility model are as follows: The multi-functional roadway repair machine of this utility model has a reasonable structure. It utilizes the water leakage hole on the bucket and sets up a plate compactor assembly that is detachably and fixedly connected to the water leakage hole, without affecting the normal digging function of the bucket. When it is necessary to flatten the road surface, the plate compactor assembly is fixed on the bucket, and the bucket is driven to descend so that the compactor plate flattens the road surface.

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0020] like Figure 1-5 As shown, the multi-functional tunnel repair machine of the embodiment includes a vehicle body 1, a boom 2 connected to the vehicle body 1, and a bucket 3 disposed on the boom 2. The bucket 3 is provided with a water leakage hole 31. It also includes a plate compactor assembly. A fixing component for fixing the plate compactor assembly to the bucket 3 is disposed between the plate compactor assembly and the water leakage hole 31.

[0021] This design allows for flexible function switching without wasting the value of the original equipment: the bucket is the basic excavation component of the roadway repair machine. The bucket has a built-in water leakage hole, and the plate compactor assembly is detachably connected to the water leakage hole through a fixing component. This means that the equipment does not require additional modifications. Normally, the bucket can be used to complete basic excavation operations such as breaking up surrounding rock and clearing debris. When it is necessary to level the roadway surface, the function can be switched simply by installing the plate compactor assembly on the bucket through the fixing component. This retains the original function of the bucket and adds a leveling function, avoiding the idleness of a single equipment function.

[0022] Simplified installation logic and protection of bucket structural integrity: The fixing components are directly fixed using the bucket's built-in drainage holes, eliminating the need for additional holes or welding connectors on the bucket. This saves on secondary modification of the bucket, reducing modification costs, and preserves the original structural strength of the bucket to the greatest extent, avoiding problems such as uneven stress and easy damage caused by additional holes. At the same time, the detachable fixing method also makes the assembly and disassembly of the plate compactor components more convenient.

[0023] According to one embodiment of the present invention, the plate compactor assembly includes a base 4 and a compaction plate 5. The base 4 is connected to the bucket 3, and the compaction plate 5 is disposed below the base 4.

[0024] This design achieves a stable connection through the base and leverages the controllability advantage of the bucket: the base serves as the connecting carrier between the plate compactor assembly and the bucket, directly connecting to the bucket and enabling the plate compactor assembly to be stably fixed on the bucket.

[0025] According to one embodiment of the present invention, the fixing component includes a screw 41 disposed on the base 4, the screw 41 passing through the drain hole 31, and a nut 42 threadedly connected to the screw 41, and the bucket 3 is clamped between the base 4 and the nut 42.

[0026] This design, with its detachable threaded connection, allows for flexible function switching: the fixing component uses a threaded connection method of "screw through the drainage hole + nut locking", making disassembly and assembly simple: when it is necessary to level the road surface, simply pass the screw through the drainage hole of the bucket and tighten the nut to quickly fix the plate compactor component on the bucket; when leveling is not required, simply unscrew the nut and pull out the screw to disassemble the plate compactor component without affecting the original digging and slag removal functions of the bucket.

[0027] According to one embodiment of the present invention, an inner pad 6 is sandwiched between the nut 42 and the inner wall of the bucket 3. The inner pad 6 is fitted to the inner wall of the bucket 3. The nut 42 is in surface contact with the inner pad 6. The inner pad 6 is provided with a first through hole 61 through which the screw 41 passes.

[0028] According to one embodiment of the present invention, an outer pad 7 is sandwiched between the base 4 and the outer wall of the bucket 3. The outer pad 7 is fitted to the outer wall of the bucket 3. The base 4 is in surface contact with the outer pad 7. The outer pad 7 is provided with a second through hole 71 for the screw 41 to pass through.

[0029] This design increases the contact area, preventing localized pressure damage to the bucket's outer wall: the outer pad is "fitted" to the bucket's outer wall and "face-contact" with the base. Compared to the base directly contacting the bucket's outer wall, the outer pad fills the gap between them, distributing the base's pressure over a larger contact area. According to the principle of pressure transmission, increased contact area reduces pressure per unit area, preventing dents, deformation, or wear on the bucket's outer wall due to excessive localized stress, thus protecting the integrity of the bucket's original structure.

[0030] According to one embodiment of the present invention, the ramming plate 5 and the base 4 are rotatably connected by a ball joint.

[0031] This design allows the tamping plate to autonomously adapt to uneven road surfaces, ensuring full contact between the tamping plate and the road surface. During tunnel repair, road surfaces often exhibit undulations and localized tilts. If the tamping plate is fixedly connected to the base, it can only maintain a single angle, easily leading to localized suspension and uneven compaction. The ball-head rotating connection allows the tamping plate to flexibly adjust its angle around the ball head, autonomously adapting to the real-time shape of the road surface and ensuring that the bottom surface of the tamping plate always maintains full and tight contact with the road surface.

[0032] According to one embodiment of the present invention, a first hydraulic cylinder 21 is provided between the boom 2 and the bucket 3, and a first baffle 22 is fixedly provided on the boom 2, with the first baffle 22 positioned above the first hydraulic cylinder 21.

[0033] With this design, the first baffle is fixed to the boom and located above the hydraulic cylinder, directly providing protection against the harsh environment of tunnel operations (fractured surrounding rock is prone to falling gravel and dust).

[0034] According to one embodiment of the present invention, a pusher 8 is further provided below the vehicle body 1, and a second hydraulic cylinder 81 is provided between the pusher 8 and the vehicle body 1.

[0035] The pusher expands core operational functions and reduces reliance on manual labor and equipment handling: The pusher is located under the vehicle body, directly supplementing the pre-treatment and cleaning capabilities of roadway repair: Replacing manual cleaning, in the early stages of roadway repair, there are often debris such as broken surrounding rock fragments and scattered slag. The pusher can directly push forward and sweep, quickly collecting or cleaning the debris to a designated area without the need for manual bending over to clean, greatly reducing the labor intensity of workers and demonstrating the multi-functional characteristics of the roadway repair machine.

[0036] According to one embodiment of the present invention, a rotary cylinder 9 is provided between the vehicle body 1 and the boom 2, and a second baffle 91 is fixedly provided on the vehicle body 1, the second baffle 91 being disposed above the rotary cylinder 9.

[0037] With this design, the second baffle is fixed to the vehicle body and located above the rotary cylinder, directly providing protection against the harsh environment of the tunnel where "broken surrounding rock is prone to falling and dust concentration is high".

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
