Description

Technical Field

[0001] This invention relates to the field of railway tunnel construction, and specifically to a railway tunnel working vehicle. Background Technology

[0002] With the rapid development of my country's transportation industry and the accelerated pace of high-grade highway and railway construction, the maintenance and repair of tunnels has become particularly important. To ensure rapid remediation of tunnel defects and reduce disaster management costs within the limited "maintenance window," it is essential to guarantee the quality of tunnel construction and improve construction efficiency.

[0003] The methods for roughening existing railway tunnels in the treatment of defects are divided into manual roughening and mechanized roughening. Manual roughening requires manual use of hand tools to roughen the tunnel surface, resulting in inconsistent roughening effects, low efficiency, and high safety risks. While using machine-mounted mechanized roughening machines, due to tunnel curvature limitations, generally only allows for roughening operations with a single row of roughening heads, which improves construction efficiency to some extent, there is an urgent need for an adaptive roughening device that can be used in existing railway tunnels to meet the requirements for efficient and high-quality roughening operations in the treatment of defects in existing railway tunnels.

[0004] In practical engineering work, the following problems exist:

[0005] First, existing chipping machines cannot perform large-area chipping operations; simply increasing the size of the chipping machine hinders its flexibility; and continuous operation of the chipping machine is also impossible.

[0006] Second, if the flexibility and stability of existing shaving machines are increased, the corresponding decrease will be.

[0007] Third, dust is easily generated during the existing roughening operation. For tunnel dust, a separate spraying device is generally used. However, this requires the addition of a spraying truck, which is costly. In addition, there will be a time delay in the additional spraying, that is, the dust will be sprayed only after it has spread.

[0008] Fourth, existing chiseling machines are often designed for flat surface operations, and the technology for curved surface operations is not yet mature.

[0009] Fifth, in existing railway tunnel operations, there are obstacles in the tunnel that hinder the operation of the work vehicle, and there are significant difficulties in finding a way to bypass these obstacles. Summary of the Invention

[0010] To overcome the above problems, the present invention proposes a solution that addresses multiple problems simultaneously.

[0011] The technical solution adopted by this invention to solve its technical problem is as follows: a railway tunnel working vehicle, including a car body, a slewing mechanism, a driver's cab, a hydraulic cylinder, a telescopic robotic arm, and a chiseling device; wherein the telescopic robotic arm includes a first-stage robotic arm, a second-stage robotic arm, and a third-stage robotic arm; wheels are provided under the car body and run on the track by means of the wheels; the driver's cab and the slewing mechanism are provided on the car body; the slewing mechanism includes a disc, which can rotate relative to its own axis; the telescopic robotic arm and the hydraulic cylinder are pivotally mounted on the disc via a hinge seat; the hydraulic cylinder can drive the first-stage robotic arm to rotate; the second-stage robotic arm can extend and retract relative to the first-stage robotic arm, and the third-stage robotic arm can extend and retract relative to the second-stage robotic arm; the chiseling device includes a chiseling control rod and a chiseling assembly; the chiseling control rod is connected to the third-stage robotic arm, and the end of the chiseling control rod is connected to the chiseling assembly.

[0012] The chiseling control rod includes a telescopic cylinder, a telescopic body, a rotary drive mechanism, a main connecting rod, an extension rod, and an extension plate; the chiseling assembly includes a chiseling unit and a multi-stage telescopic rod; the chiseling unit is divided into a main chiseling unit, a connecting chiseling unit, and a locking chiseling unit; each chiseling unit includes a chiseling head, a chiseling bracket, an atomizing spray head, a guide wheel, and a guide wheel bracket.

[0013] The telescopic body can extend and retract within the telescopic cylinder. The telescopic body is a round rod with a flat portion. An extension plate is provided at each end of the flat portion, and a main connecting rod is provided between the two extension plates. The rotary drive mechanism drives the main connecting rod to rotate. Four extension rods are provided on the main connecting rod. The four extension rods are connected to the main chiseling unit.

[0014] The main chiseling unit is rotatably connected to a connecting chiseling unit on each side. The outer sides of the two connecting chiseling units are rotatably connected to a locking chiseling unit. One locking chiseling unit is provided with two locking blocks, and the other locking chiseling unit is provided with two locking grooves. The main chiseling unit and the connecting chiseling units are controlled to rotate by a multi-stage telescopic rod, and the locking chiseling units and the connecting chiseling units are controlled to rotate by a multi-stage telescopic rod, thereby realizing the expansion and closure of the five chiseling units. In the closed state, the locking blocks are locked into the locking grooves.

[0015] In each chiseling unit, the chiseling support is block-shaped, and the chiseling support is provided with several chiseling heads and three atomizing spray heads. The chiseling support is also provided with a guide wheel support. The guide wheel support includes an upper plate, a lower plate and an elastic module. The elastic module is disposed between the upper plate and the lower plate. The lower plate is provided with a wheel frame, and the guide wheel is disposed on the wheel frame.

[0016] Preferably, the rotary drive mechanism includes a gear set and a drive motor.

[0017] Preferably, the gear set includes a driving gear and a driven gear.

[0018] Preferably, the drive motor drives the drive gear to rotate.

[0019] Preferably, the driven gear is connected to the main connecting rod.

[0020] Preferably, the number of multi-stage telescopic rods is eight.

[0021] Preferably, each chiseling unit is provided with two guide wheel brackets.

[0022] Preferably, the chisel heads are arranged in three rows.

[0023] Preferably, the chisel heads in two adjacent rows are staggered.

[0024] Preferably, a pivot structure is provided between two adjacent chiseling units.

[0025] The beneficial effects of this invention are:

[0026] The first point of the invention addresses the first point raised in the background technology by adopting Scheme 1, which constructs a multi-module chiseling device. A connecting chiseling unit is connected to each side of the main chiseling unit, and a connecting snap-fit ​​chiseling unit is attached to the outside of the chiseling machine. The chiseling units are hinged together and rotate relative to each other via telescopic rods. The overall unit formed by the chiseling units includes two states: unfolded and closed. In the unfolded state, it provides a chiseling device capable of large-area chiseling operations; in the closed state, it enables more flexible, smaller-area chiseling operations, thus balancing large-area chiseling operations with flexibility.

[0027] Second point of invention: In response to the first point raised in the background technology, the second solution is adopted to solve the continuity problem. Through the design of pulleys and pulley brackets, the roughening operation is performed by positioning when the pulleys are against the working surface. The positioning distance of the above positioning is determined by the pulley brackets. Moreover, when changing the working position, the pulleys can be used to slide without leaving the working position, thus realizing continuous operation.

[0028] Thirdly, in response to the second point raised in the background technology, two interlocking chiseling machines were designed. When the chiseling equipment is in a closed state, the two interlocking chiseling machines interlock with each other, thereby achieving stability in the closed state, thus balancing flexibility and stability.

[0029] Fourthly, regarding the third point raised in the background technology, a spray structure is integrated into the shaving machine. Due to the installation issues of spray accessories such as pipelines and water tanks (which can be optionally installed at the execution end or the remote end) after the spray structure is integrated, a secondary extension is achieved through two sets of structures: an extension plate and an extension rod. This creates a two-stage extension structure that supports a larger space between the execution rod and the shaving equipment.

[0030] Fifthly, regarding the fourth point in the background technology, the chiseling control rod can drive the chiseling assembly to achieve two motion functions: "position movement and rotation" through a telescopic hydraulic cylinder and a rotary drive mechanism. This ensures that the working surface of the chiseling assembly always fits the tunnel surface when changing working positions, guaranteeing the quality and efficiency of chiseling.

[0031] Sixth point of the invention, the fifth point proposed in response to the background technology, is that when the distance of the railway contact line is too short or the space is too small due to other objects to allow the chiseling assembly to directly reach the working surface, the chiseling assembly can be folded by the multi-stage telescopic rods on each chiseling unit. The chiseling assembly can then be sent to the back of the obstacle and close to the tunnel surface by the robotic arm. After that, the chiseling assembly can be unfolded and chiseling operations can be performed on the contact line or the area behind the obstacle. This enables chiseling operations on the area behind the contact line of existing railway lines, improving the working range and efficiency. Attached Figure Description
