Description

TECHNICAL FIELD

[0001] The present application relates to the field of railway tunnel construction, in particular to a curved surface continuous chiseling equipment. BACKGROUND

[0002] With the rapid development of China's transportation industry, the pace of high-grade highway and railway construction is accelerating, and the maintenance and repair work of the tunnel is particularly important. In order to ensure the rapid treatment of tunnel diseases within the limited "skylight" time and reduce the disaster treatment cost, it is necessary to ensure the construction quality of the tunnel and improve the construction efficiency.

[0003] The chiseling method in the disease treatment of existing railway is divided into manual chiseling and mechanized chiseling. Manual chiseling needs workers to hold tools to chisel on the surface of the tunnel, and the chiseling effect is uneven, the efficiency is low, and the safety risk is great; the mechanized chiseling machine with on-board type can only use a row of chiseling heads for chiseling operation due to the limitation of tunnel curvature, which improves the construction efficiency to a certain extent, but an adaptive chiseling device for existing railway tunnel is urgently needed to meet the efficient and high-quality chiseling operation requirements of existing railway tunnel disease treatment.

[0004] In actual engineering practice, the following problems exist:

[0005] 1. The existing chiseling machine cannot realize large-area chiseling operation; simply increasing the size of the chiseling machine will hinder the flexibility of the chiseling machine; and the continuous operation of the chiseling machine cannot be realized.

[0006] 2. If the flexibility and stability of the existing chiseling machine are increased, the performance will be correspondingly reduced.

[0007] 3. The chiseling operation in the prior art is prone to dust, and the tunnel dust is generally treated by a separate spraying device. However, this requires the addition of a spraying vehicle for conversion, which has a high cost, and the additional spraying will have a time delay, i.e. the dust will spread before it can be sprayed.

[0008] 4. The chiseling machine in the prior art is often used for flat surface operation, and the technology for curved surface operation is not mature. SUMMARY

[0009] In order to overcome the above problems, the present application provides a scheme that simultaneously solves the above problems.

[0010] The technical scheme adopted by the present application to solve its technical problems is: a curved surface continuous gouging equipment, comprising a gouging control rod and a gouging assembly; wherein the gouging control rod comprises a telescopic oil cylinder, a telescopic body, a rotary driving mechanism, a main connecting rod, an extension rod and an extension plate; the gouging assembly comprises a gouging unit and a multi-stage telescopic rod; the gouging unit is divided into a main gouging unit, a connecting gouging unit and a clamping gouging unit; each gouging unit comprises a gouging head, a gouging support, an atomizing spray head, a guide wheel and a guide wheel support;

[0011] The telescopic body is a round rod, and a flat portion is arranged on the round rod; two extension plates are arranged at the two ends of the flat portion; the main connecting rod is arranged between the two extension plates; the rotary driving mechanism drives the main connecting rod to rotate; four extension rods are arranged on the main connecting rod; the four extension rods are connected with the main gouging unit;

[0012] One connecting gouging unit is rotatably connected to the two sides of the main gouging unit; one clamping gouging unit is rotatably connected to the outer side of each of the two connecting gouging units; two clamping blocks are arranged on one of the clamping gouging units, and two clamping grooves are arranged on the other clamping gouging unit; the main gouging unit and the connecting gouging unit are controlled to rotate through the multi-stage telescopic rod, and the clamping gouging unit and the connecting gouging unit are controlled to rotate through the multi-stage telescopic rod, so that the five gouging units are unfolded and surrounded; in the surrounding state, the clamping blocks are clamped into the clamping grooves;

[0013] In each gouging unit, the gouging support is block-shaped, and a plurality of gouging heads and three atomizing spray heads are arranged on the gouging support; a guide wheel support is further arranged on the gouging support; the guide wheel support comprises an upper plate, a lower plate and an elastic module; the elastic module is arranged between the upper plate and the lower plate; a wheel frame is arranged on the lower plate; the guide wheel is arranged on the wheel frame.

[0014] Preferably, the rotary driving mechanism comprises a gear set and a driving motor.

[0015] Preferably, the gear set comprises a driving gear and a driven gear.

[0016] Preferably, the driving motor drives the driving gear to rotate.

[0017] Preferably, the driven gear is connected with the main connecting rod.

[0018] Preferably, the number of the multi-stage telescopic rods is eight.

[0019] Preferably, two guide wheel supports are arranged on each gouging unit.

[0020] Preferably, the gouging heads are arranged in three rows.

[0021] Preferably, the chisel heads in two adjacent rows are staggered.

[0022] Preferably, a pivot structure is provided between two adjacent chiseling units.

[0023] The beneficial effects of this invention are:

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.
