As shown in fig. 1, a device for correcting a tunnel profile according to an embodiment of the present application includes a feed beam 2, a feed mechanism 3, a slide holder 4, and a breaking hammer assembly 6.
The pushing beam 2 is a long beam, a sliding rail is arranged on one side surface of the pushing beam 2, and the sliding seat 4 is slidably connected to the sliding rail of the pushing beam 2 and can freely slide along the length direction of the pushing beam 2. The pushing mechanism 3 is mounted on the pushing beam 2 and is used for pushing the sliding seat 4 to freely slide along the length direction of the pushing beam 2, the pushing mechanism 3 can be any one of a hydraulic telescopic cylinder, an electric telescopic cylinder and a pneumatic telescopic cylinder, one end of the pushing mechanism is connected with one side end of the pushing beam 2, and the other end of the pushing mechanism is connected with the sliding seat 4. The breaking hammer assembly 6 is mounted on the sliding seat 4, and the breaking hammer assembly 6 can adopt a hydraulic breaking hammer in the prior art, drives a piston to reciprocate by taking hydrostatic pressure as power, and impacts a drill rod at high speed during the piston stroke, so that the drill rod breaks solids such as ore, concrete and the like. The embodiment of the application can correct the profile surface of the tunnel through the breaking hammer assembly 6, thereby solving the problem of undermining of the tunnel.
In some embodiments, the breaking hammer assembly 6 can also take other specifically designed forms. For example, as shown in fig. 1, the breaking hammer assembly 6 may include a breaking hammer body 7 and a tooth 8. Wherein, the breaking hammer main body 7 is arranged on the sliding seat 4 and freely slides on the propelling beam 2 along with the sliding seat 4. The teeth 8 are attached to the main body 7, and the teeth 8 are preferably attached to the main body 7 on the side away from the propulsion mechanism 3 in view of crushing effect and easy operability.
The bucket teeth 8 can be arranged in a plurality and are arranged on the breaking hammer main body 7 in a row, so that the breaking hammer main body 7 can have larger breaking contact area with the inner wall of a tunnel during action, and a better trimming effect is achieved. The breaking hammer body 7 is at least provided with a row of bucket teeth 8, and in each row of bucket teeth 8, the length of the bucket teeth 8 positioned at the middle position is longer than that of the bucket teeth 8 positioned at the two sides, so that each row of bucket teeth 8 can form an overall arc-shaped profile, thereby being more beneficial to removing rocks and enabling the profile of the tunnel after trimming to keep an arc-shaped section.
Moreover, the whole length of one row of teeth 8 in two adjacent rows of teeth 8 can be designed to be larger or smaller than the whole length of the other row of teeth 8. For example, as shown in fig. 1, when only two rows of teeth 8 are provided, the overall length of the teeth 8 located at the upper row in the working state is smaller than that of the teeth 8 located at the lower row, because the inner wall of the tunnel is usually trimmed in a manner from top to bottom in the process of trimming the tunnel, the teeth 8 located at the lower row are firstly contacted with the inner wall of the tunnel, and after the teeth 8 located at the lower row remove the corresponding earth rock of the inner wall of the tunnel, the teeth 8 located at the upper row can be contacted with the inner wall of the tunnel, so that the trimmed inner wall of the tunnel has a better arc profile. In some cases, the inner wall of the tunnel may be trimmed in a bottom-up manner, where the overall length of the teeth 8 located in the upper row in the working state needs to be set to be greater than the overall length of the teeth 8 located in the lower row, so as to trim the tunnel into a better arc profile. Meanwhile, as the inner wall of the tunnel is arc-shaped, the whole length of two adjacent rows of bucket teeth 8 is set to be in a step shape, which is favorable for keeping the profile shape of the inner wall of the tunnel after finishing more in line with the requirements. And, set up the whole length of two adjacent rows of bucket teeth 8 to the ladder-shaped, can also realize such technological effect: the longer row of bucket teeth 8 is contacted with the rock mass and thinned, and then the shorter row of bucket teeth 8 is contacted with the rock mass and thinned further, so that the bucket teeth 8 can be prevented from bearing larger impact force at one time, the rock cutting efficiency can be improved, and the rock cutting efficiency is better especially when facing large rock mass.
A group of spray heads 10 can be additionally arranged on the breaking hammer main body 7 at the position close to the bucket teeth 8 so as to reduce the dust concentration generated when the bucket teeth 8 break rocks.
In order to know the rock breaking condition of the bucket tooth 8 at any time, the embodiment of the application can also be provided with an image acquisition unit 1, such as a camera, on the propelling beam 2. The image acquisition unit 1 may be mounted on the feed beam 2 at an end remote from the breaking hammer assembly 6 to avoid earth and stone splatter damaging the image acquisition unit 1.
Meanwhile, in order to avoid the situation that the device is inclined to dig, surpasses dig in the tunnel finishing process, as shown in fig. 1, at least two distance sensors 17 can be installed on the propelling beam 2, and the distance sensors 17 can be selected as sensors capable of detecting distance, such as a laser range finder, an ultrasonic sensor and the like. For example, two distance sensors 17 may be disposed at intervals at the bottom of the push beam 2, and the two distance sensors 17 may detect the distance between the push beam 2 and the inner wall of the tunnel at the same time, for example, the two distance sensors 17 detect the distance of the left side wall of the tunnel at the same time, or detect the distance of the right side wall of the tunnel at the same time, or detect the distance of the left side wall of the tunnel at one time, and detect the distance of the right side wall of the tunnel at the other time. If the distances detected by the two distance sensors 17 are basically equal, or the detected distances are always kept unchanged or only changed in a small range, the length direction of the propelling beam 2 is considered to be always parallel to the axis of the tunnel, and at the moment, the device is used for trimming the inner wall of the tunnel to obtain a correct trimming path, so that the situations of partial excavation, over excavation and the like can not occur. If the distance difference detected by the two distance sensors 17 is large, or the front-back variation range of the detected distance is large, it is indicated that the length direction of the push beam 2 and the axis of the tunnel are deviated, and at this time, when the device is adopted for trimming, the conditions of partial digging, super digging and the like are easy to occur, and the trimming path of the breaking hammer assembly 6 should be adjusted in time by controlling the yaw driving mechanism 15 and/or the pitch driving mechanism 13.
To further increase the rock breaking efficiency of the tooth 8, embodiments of the application may also include a vibratory drive 9, such as a vibratory motor or other drive that may be operated to reciprocate at high frequencies. The vibration driving mechanism 9 is mounted on the sliding seat 4 and freely slides on the push beam 2 along with the sliding seat 4. The breaking hammer assembly 6 is connected to the movable end of the vibration driving mechanism 9, and the vibration driving mechanism 9 is used for driving the breaking hammer assembly 6 to vibrate in a reciprocating manner in the length direction of the propelling beam 2, so that high-frequency rock breaking is achieved.
To further increase the flexibility of movement of the breaking hammer assembly 6, embodiments of the present application may further comprise a rotational drive mechanism 5, such as a motor. The rotary driving mechanism 5 is mounted on the sliding seat 4 and moves along with the sliding seat 4, the breaking hammer assembly 6 is connected to a rotating shaft of the rotary driving mechanism 5, and the rotary driving mechanism 5 is used for driving the breaking hammer assembly 6 to rotate in the direction perpendicular to the length direction of the propelling beam 2, so that the construction angle of the breaking hammer assembly 6 is adjusted.
In addition, an arc-shaped track 11 may be additionally installed between the breaking hammer main body 7 and the sliding seat 4, where the arc-shaped track 11 is used to guide the breaking hammer assembly 6 to implement rotation (about 90 °) within a range of 180 ° in a direction perpendicular to the length direction of the thrust beam 2, and the breaking hammer assembly 6 can be ensured to rotate smoothly in cooperation with the rotation driving mechanism 5.
As shown in fig. 2, the device for correcting the tunnel profile according to the embodiment of the application can be used in cooperation with a trolley, and only the push beam 2 is required to be connected with the arm support of the trolley, so that the inner wall of the tunnel can be finished by operating the trolley. To further facilitate connection of embodiments of the present application to the trolley, and to adjust the position and angle of connection, embodiments of the present application may further include a base 12, a pitch drive mechanism 13, and a stand 14. The base 12 is connected with the propelling beam 2; one end of the support 14 is hinged to one end of the base 12, and the other end of the support 14 is hinged to the other end of the base 12 through the pitch driving mechanism 13. The pitch drive mechanism 13 may be any one of a hydraulic telescopic cylinder, an electric telescopic cylinder, and a pneumatic telescopic cylinder. The support 14 may be connected to the arm support of the trolley, such that the pitch angle of the feed beam 2 relative to the support 14, i.e. the breaking hammer assembly 6, may be adjusted by extension and shortening of the pitch drive mechanism 13.
Meanwhile, the embodiment of the present application may further include a yaw drive mechanism 15 and a connection base 16. One end of the connecting seat 16 is used for being connected with a cantilever crane of the trolley, and the other end of the connecting seat 16 is hinged with one side, away from the pitching driving mechanism 13, of the support 14. The yaw driving mechanism 15 may be any one of a hydraulic telescopic cylinder, an electric telescopic cylinder, and a pneumatic telescopic cylinder, and has one end hinged to the connection base 16 and the other end hinged to the support 14. The yaw driving mechanism 15 may be provided in two and located at both sides of the connection base 16, respectively. For example, when the pitch drive mechanism 13 is used to adjust the pitch angle of the pitch beam 2, embodiments of the present application may adjust the active yaw angle of the pitch beam 2 through the yaw drive mechanism 15, i.e., the pitch drive mechanism 13 and the yaw drive mechanism 15 may enable adjustment of the pitch beam 2 in two degrees of freedom.
