The groove wall leveling device of a twin-wheel groove milling machine

Abstract

This invention discloses a groove wall leveling device for a twin-wheel grooving machine. The device includes a mounting frame, a cam, and a leveling plate positioned laterally relative to the mounting frame via a lateral elastic telescopic part. The leveling plate reciprocates between outward and inward lateral movement due to the rotational push of the cam and the elastic pull of the lateral elastic telescopic part. During outward lateral movement, the leveling plate strikes the groove wall formed by the milling wheel. An inertial impact component includes a housing and an impact column slidably disposed within the housing. The leveling plate has through holes coaxially corresponding to the impact column. At the moment the outward-moving leveling plate strikes the groove wall, the impact column, driven by the leveling plate, impacts the groove wall due to inertial motion. This invention first levels the groove wall over a large area using a reciprocating leveling plate, and then levels it over a small area inertial impact in the height direction using an inertial impact component, achieving groove wall leveling during the milling process and improving the accuracy and efficiency of groove wall leveling.

Description

Technical Field

[0001] This invention belongs to the technical field of groove wall leveling for twin-wheel groove milling machines, and particularly relates to a groove wall leveling device for twin-wheel groove milling machines. Background Technology

[0002] The twin-wheel trenching machine is currently the world's most advanced specialized equipment for diaphragm wall construction. It is primarily used for trenching in deep foundation projects such as urban rail transit, bridge anchorages, and high-rise building basements, for waterproofing walls, retaining walls, and load-bearing walls. Its working principle involves first cutting and breaking the rock strata with the milling wheels, and then circulating the slag through a pump unit. While the verticality of the wall surface can be guaranteed during the trenching process, the precision is not high, requiring post-processing. The lack of measures for smoothing the wall surface during trenching affects the overall efficiency of the trenching operation. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a groove wall leveling device for a twin-wheel groove milling machine. First, the groove wall is leveled by a reciprocating leveling plate, and then the groove wall is leveled by a small-range inertial impact component in the height direction. This realizes the groove wall leveling operation during the groove milling process and improves the accuracy and efficiency of groove wall leveling.

[0004] Technical Solution: To achieve the above objectives, the present invention provides a groove wall leveling device for a twin-wheel grooving machine, comprising a groove wall leveling device mounted on the wheel washing machine frame of the twin-wheel grooving machine. This device includes a mounting frame, a cam rotatably mounted on the frame, and a leveling plate positioned laterally relative to the mounting frame via a lateral elastic extension portion. The leveling plate undergoes a reciprocating motion of outward and inward lateral movement driven by the rotation of the cam and the elastic pull of the lateral elastic extension portion. When the leveling plate moves outward, it strikes the groove wall of the deep groove formed by the milling wheel. The device also includes an inertial impact component perpendicular to the surface of the leveling plate. The inertial impact component includes a housing and an impact column slidably disposed within the housing. A through hole corresponding to the impact column is provided on the leveling plate. At the moment the outward-moving leveling plate strikes the groove wall, the impact column, driven by the leveling plate, strikes the groove wall of the deep groove due to inertial motion.

[0005] Furthermore, the cam is located in the middle of the mounting frame, and the flat plate is a pair connected to the mounting frame by a transverse elastic telescopic part. The pair of flat plates are symmetrically arranged about the mounting frame, forming a double-plate striking flattening mechanism.

[0006] Furthermore, the shell opening is installed in the through hole on the flat plate. The shell is composed of a sleeve mounting part, a circumferential array rod part and a base plate part connected in sequence. The impact column is slidably disposed relative to the sleeve mounting part. The head of the impact column is an impact end face with a vertical planar structure. The tail of the impact column is provided with a limiting rod that slides through the base plate part. The tail end of the limiting rod is provided with a limiting expansion head. The impact column is prevented from inertially moving outward and detaching from the shell relative to the shell by axial limiting of the limiting expansion head.

[0007] Furthermore, the circumferential array rod portion is arranged circumferentially according to the circumferential contour of the sleeve mounting portion, so that the shell body portion near the bottom plate of the outer shell composed of the sleeve mounting portion and the circumferential array rod portion has a hollow structure, and the outer shell maintains the pressure balance between the inside and outside of the shell through the hollow structure of the shell body portion.

[0008] Furthermore, the inertial impact components are arranged in a row in linear arrays on the upper and lower parts of the flat plate.

[0009] Furthermore, the cam is rotatably mounted on the mounting bracket connected to the wheel washing machine frame via a camshaft. Multiple cams are arranged on the same camshaft along the width direction of the flat plate, and each cam maintains the same structural posture when mounted on the camshaft.

[0010] Furthermore, it includes a cam drive mechanism corresponding to the cam, the cam drive mechanism driving the camshaft to drive each of the cams to rotate synchronously; the cam drive mechanism includes a motor and a gear set, the motor being connected to the camshaft of the cam through the gear set.

[0011] Furthermore, the pushing end of the cam that rotates to push the flat plate is a rotating end, and the cam pushes the flat plate through this rotating end in a rolling contact manner.

[0012] Furthermore, the cam's driving end is rotatably mounted with a roller or embedded with a ball, and the cam's driving end forms the rotating end through the roller or ball.

[0013] Furthermore, the lateral elastic telescopic part includes a lateral guide sleeve, a lateral guide post, and a lateral spring, and the lateral guide sleeve and the lateral guide post, which are axially displaced, are elastically connected by the lateral spring.

[0014] Beneficial effects: This invention first uses a reciprocating flattening plate to flatten the groove wall over a large area by hammering. This flattening range is large, and the power source is the impact-driven push of the cam, which is fast, powerful, and has a good flattening effect. Then, an inertial impact component is used to flatten the groove wall in a small area of ​​inertial impact in the height direction. No external impact power is required. Moreover, the inertial impact component is arranged in a row of linear arrays at the top and bottom of the flattening plate to achieve more refined impact flattening in the height direction of the deep groove. The hammering flattening of the flattening plate is a large-scale primary flattening operation, and the inertial impact flattening of the inertial impact component is a small-scale secondary flattening operation, thereby achieving high-precision and high-efficiency groove wall flattening operation in the groove milling process.

[0019] The invention will now be further described with reference to the accompanying drawings.

[0020] As attached Figure 1 and attached Figure 2 As shown, the groove wall leveling device of the twin-wheel grooving machine includes a groove wall leveling device 200 mounted on the wheel washing machine frame 100 of the twin-wheel grooving machine. The groove wall leveling device 200 includes a mounting frame 1, a cam 2 rotatably mounted on the frame 1, and a leveling plate 4 positioned laterally relative to the mounting frame 1 via a transverse elastic telescopic part 3. The leveling plate 4 is in a reciprocating motion of outward and inward transverse movement due to the rotational push of the cam 2 and the elastic pull of the transverse elastic telescopic part 3. When the leveling plate 4 moves outward, it strikes the groove wall of the deep groove 11 formed by the grooving wheel 10. (See attached diagram) Figure 3 and attached Figure 4As shown, it also includes an inertial impact component 5 disposed on the surface of the vertical flat plate 4. The inertial impact component 5 includes a housing 51 and an impact column 52 slidably disposed in the housing 51. The flat plate 4 has a through hole 40 coaxially corresponding to the impact column 52. At the moment when the flat plate 4 moves outward and strikes the groove wall, the impact column 52, driven by the flat plate 4, strikes the groove wall of the deep groove 11 by inertial motion. This invention first uses a reciprocating flattening plate 4 to flatten the groove wall over a large area by striking it. This flattening range is large, and the power source is the impact push of the cam 2, which is fast, powerful, and has a good flattening effect. Then, an inertial impact component 5 is used to flatten the groove wall in a small area in the height direction by inertial impact. No external impact power is required. Moreover, the inertial impact component 5 is arranged in a linear array on the upper and lower parts of the flattening plate 4 to achieve more refined impact flattening in the height direction of the deep groove 11. The striking flattening of the flattening plate 4 is a large-scale primary flattening operation, and the inertial impact flattening of the inertial impact component 5 is a small-scale secondary flattening operation, thereby achieving high-precision and high-efficiency groove wall flattening operation in the groove milling process.

[0021] To achieve comprehensive coverage of the trench wall leveling operation and further improve efficiency, the present invention includes, as shown in the appendix... Figure 1 and attached Figure 2 As shown, the cam 2 is located in the middle of the mounting bracket 1, and the flattening plates 4 are a pair connected to the mounting bracket 1 respectively by transverse elastic telescopic parts 3. These two pairs of flattening plates 4 are symmetrically arranged about the mounting bracket 1, forming a double-plate striking flattening mechanism. (See attached diagram) Figure 2 In this invention, the groove-impact wall-leveling device of the double-plate striking and leveling mechanism is only one embodiment of the installation method, namely, leveling the two groove walls of the deep groove 11 axially pointing towards the milling wheel 10. However, the overall purpose is to level the groove walls of the deep groove 11. Since the groove walls of the deep groove 11 are four surfaces, a second embodiment of the groove-impact wall-leveling device of the double-plate striking and leveling mechanism is to level the other two groove walls of the deep groove 11 non-axially pointing towards the milling wheel 10. There is also a third embodiment of the installation method of the groove-impact wall-leveling device of the double-plate striking and leveling mechanism: using two groove-impact wall-leveling devices arranged vertically and horizontally, one of which levels the two groove walls of the deep groove 11 axially pointing towards the milling wheel 10, and the other leveling device levels the other two groove walls of the deep groove 11 non-axially pointing towards the milling wheel 10.

[0022] As attached Figure 3 and attached Figure 4As shown, the shell opening of the outer casing 51 is installed through the through hole 40 on the flat plate 4. The outer casing 51 is composed of a sleeve mounting part 5.1, a circumferential array rod part 5.2, and a base plate part 5.3 connected in sequence. The impact column 52 is coaxially slidably disposed relative to the sleeve mounting part 5.1. The head of the impact column 52 is an impact end face with a vertical planar structure. The tail of the impact column 52 is provided with a limiting rod 53 that slides through the base plate part 5.3. The tail end of the limiting rod 53 is provided with a limiting expansion head 54. The impact column 52 is prevented from inertially moving outward and detaching from the outer casing 51 by the axial limitation of the limiting expansion head 54. When the flat plate 4 is reset, it will also drive the impact column 52 to retract into the outer casing 51 and reset, that is, the impact column 52 impacts the base plate part 5.3 and stops at the reset position. The limiting expansion head 54 can axially limit the outward movement of the impact column 52 to prevent the shell from falling off. At the same time, the existence of the limiting expansion head 54 also ensures that the impact column 52 can be successfully reset.

[0023] The circumferential array rod part 5.2 is arranged circumferentially according to the circumferential contour of the sleeve mounting part 5.1, so that the shell body part of the outer shell 51 formed by the sleeve mounting part 5.1 and the circumferential array rod part 5.2 near the bottom plate part 5.3 has a hollow structure. The outer shell 51 maintains the pressure balance inside and outside the shell through the hollow structure of the shell body part, reduces the resistance to the displacement of the impact column 52, and ensures the smoothness of the inertial displacement of the impact column 52.

[0024] The cam 2 is rotatably mounted on the mounting bracket 1 connected to the wheel washing machine frame 100 via a camshaft. Multiple cams 2 are arranged along the width direction of the flat plate 4 on the same camshaft, and each cam 2 maintains the same structural posture while mounted on the camshaft. The invention includes a cam drive mechanism 6 corresponding to the cam 2, which drives the camshaft to rotate synchronously with each cam 2. The cam drive mechanism 6 includes a motor and a gear set, with the motor connected to the camshaft of the cam 2 via the gear set.

[0025] To reduce structural wear between cam 2 and flat plate 4, as shown in the attached... Figure 2 Or attached Figure 3 As shown, the pushing end of the cam 2 that rotates to push the flat plate 4 is a rotating end 20. The cam 2 pushes the flat plate 4 through this rotating end 20 in a rolling contact manner. The pushing end of the cam 2 is axially mounted with a roller or embedded with a ball, and the rotating end 20 is formed by the roller or ball.

[0026] In this invention, the transverse elastic telescopic part 3 includes a transverse guide sleeve 31, a transverse guide post 32, and a transverse spring. The transverse guide sleeve 31 and the transverse guide post 32, which are axially displaced, are elastically connected by the transverse spring.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
