Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic double-wheel slot milling machines, and more specifically to a hydraulic double-wheel slot milling machine. Background Art

[0002] The hydraulic double-wheel slotting machine is mainly used for the slotting construction of underground continuous walls. The hydraulic double-wheel slotting machine is mainly composed of a winch structure, a belt, a hydraulic support structure, a guide wheel structure, a hanger and two sets of hydraulic milling wheels. The belt on the winch structure is used to lift the hanger through the guide wheel structure, and then the hanger position is adjusted through the hydraulic support structure, and then the winch structure is controlled to release the belt, so that the hanger descends. At this time, the two sets of hydraulic milling wheels under the hanger work to slot the ground.

[0003] When the existing hydraulic double-wheel slot milling machine is working, if the hydraulic milling wheel encounters a hard object such as a stone, a mutual collision force will be generated, which may cause the hanger to vibrate and rebound. Because the hanger is hoisted by a winding belt, its stability is not very good. Therefore, it is easy to cause deflection during the vibration and rebound of the hanger, which can easily lead to deviations in the subsequent hydraulic milling wheel slotting and affect the verticality of the slotting. In view of this, we propose a hydraulic double-wheel slot milling machine. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a hydraulic double-wheel slot milling machine to solve the problem that when the current hydraulic double-wheel slot milling machine encounters hard objects such as stones, the hanger vibrates and rebounds, which easily causes deviations in the subsequent hydraulic milling wheel slotting and affects the technical problem of the verticality of the slotting.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a hydraulic double-wheel slot milling machine, comprising a base, a capstan structure is arranged at the rear side of the top of the base, a belt is arranged on the capstan structure, a hydraulic support structure is arranged at the front side of the top of the base, a guide wheel disc structure is arranged at the top of the hydraulic support structure, a hanger is arranged at the free end of the belt passing through the guide wheel disc structure, and two groups of hydraulic milling wheels are arranged at the bottom of the hanger;

[0006] A driving frame structure is arranged on the top of the base, two groups of symmetrical triangular limit frames are arranged on the top of the driving frame structure, and welding strips are arranged on the sides of the two groups of triangular limit frames on opposite sides, and limiting grooves corresponding to the welding strips are opened on both sides of the hanger;

[0007] A rectangular through hole is provided on the side of the welding strip, two groups of buckling strips are slidably arranged inside the rectangular through hole, and a plurality of groups of springs are arranged between the two groups of buckling strips. The buckling strips are inclined toward one side of the hanger, and a matching groove symmetrical to the buckling strip is provided inside the limiting groove.

[0008] The utility model adopts the designed driving frame structure, triangular limiting frame and welding strip. After the hanger is placed, the driving frame structure can be used to adjust the position of the two sets of triangular limiting frames, so that the welding strips on the two sets of triangular limiting frames are directly inserted into the limiting grooves of the hanger, thereby limiting the hanger and making the hanger only liftable in the vertical direction. Therefore, when the hydraulic milling wheel encounters hard objects such as stones during the grooving process, the hanger will only move in the vertical direction during the vibration rebound process, and will not deflect, thereby ensuring the verticality of the subsequent hydraulic milling wheel grooving on the hanger and avoiding deviation. Rectangular through holes, buckling strips and springs are provided on the welding strips, and matching grooves matching the buckling strips are provided on the limiting grooves, and the primary surface of the buckling strips adopts The inclined design allows the welding strip to enter the limiting groove and the buckling strip to retract to the rectangular through hole under the cooperation of its inclined surface and the limiting groove. At this time, the spring is in a compressed state. When the welding strip is fully inserted into the limiting groove, the buckling strip will be ejected under the reset of the spring and extend into the matching groove. At this time, the flat side of the buckling strip will be pressed against the side wall of the matching groove, so that the two sets of triangular limit frames and the hanger are combined to form an integral structure, which can greatly ensure the stability between the three, making the two sets of triangular limit frames less likely to deform, thereby better ensuring the limiting stability of the two sets of triangular limit frames on the hanger. In addition, in this way, the welding strip can be directly docked with the hanger from the side, which is convenient for the connection operation between the two.

[0009] Preferably, the drive frame structure includes two groups of mounting bars, the two groups of mounting bars are slidably arranged on the base, two groups of symmetrical first hydraulic cylinders are arranged between the two groups of mounting bars, the cylinder bodies of the first hydraulic cylinders are connected to the base, and the piston ends of the first hydraulic cylinders are connected to the mounting bars.

[0010] Preferably, second hydraulic cylinders are arranged on opposite sides of the two groups of mounting bars, and the piston ends of the second hydraulic cylinders are connected to the triangular limit frame via a connecting block.

[0011] Preferably, a T-shaped opening groove is provided at the top of the mounting bar, and both ends of the opening groove are open; a T-shaped sliding bar is arranged at the bottom of the triangular limiting frame, and the sliding bar is located in the opening groove.

[0012] Preferably, two groups of second sliding grooves symmetrical to the mounting bar are provided on the top of the base, and second sliding blocks are slidably arranged inside the second sliding grooves, and the second sliding blocks are connected to the mounting bar.

[0013] Preferably, first sliding grooves are formed on both side walls inside the rectangular through hole, and two groups of first sliding blocks are slidably arranged inside the first sliding grooves, and the first sliding blocks are connected to corresponding buckling strips.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model adopts the designed driving frame structure, triangular limit frame and welding strip. After the hanger is placed, the driving frame structure can be used to adjust the position of the two sets of triangular limit frames, so that the welding strips on the two sets of triangular limit frames are directly inserted into the limit grooves of the hanger, thereby limiting the hanger and making the hanger only lift and lower in the vertical direction. Therefore, when the hydraulic milling wheel encounters hard objects such as stones during the grooving process, the hanger will only move in the vertical direction during the vibration and rebound process, and will not deflect, thereby ensuring the verticality of the subsequent hydraulic milling wheel grooving on the hanger and avoiding deviations. This solves the technical problem that when the current hydraulic double-wheel milling machine encounters hard objects such as stones, the hanger is prone to deflection during the vibration and rebound process, which easily leads to deviations in the subsequent hydraulic milling wheel grooving and affects the verticality of the grooving. Therefore, the utility model has the advantage of more precise grooving.

[0016] 2. The utility model also provides a rectangular through hole, a buckling strip and a spring on the welding strip, and a matching groove matching the buckling strip is provided on the limiting groove, and the primary surface of the buckling strip adopts an inclined design. Therefore, in the process of the welding strip entering the limiting groove, the buckling strip will retract to the rectangular through hole under the cooperation of its inclined surface and the limiting groove. At this time, the spring is in a compressed state. When the welding strip is fully inserted into the limiting groove, the buckling strip will be ejected under the reset of the spring, and the buckling strip will extend into the matching groove. At this time, the plane side of the buckling strip will be pressed against the side wall of the matching groove, so that the two groups of triangular limit frames and the hanger are combined to form an integral structure, which can greatly ensure the stability between the three, making the two groups of triangular limit frames not easy to deform, thereby better ensuring the limiting stability of the two groups of triangular limit frames on the hanger, and in this way, the welding strip can be directly connected with it from the side of the hanger, which is convenient for the connection operation of the two.

DETAILED DESCRIPTION

[0026] like Figures 1 to 7 As shown, the utility model relates to a hydraulic double-wheel slot milling machine, comprising a base 10, a winch structure 2 is arranged on the rear side of the top of the base 10, a belt 3 is arranged on the winch structure 2, a hydraulic support structure 1 is arranged on the front side of the top of the base 10, a guide wheel disc structure 4 is arranged on the top of the hydraulic support structure 1, a hanger 5 is arranged at the free end of the belt 3 passing through the guide wheel disc structure 4, and two groups of hydraulic milling wheels 6 are arranged at the bottom of the hanger 5. When grooving the ground, personnel can move the device to a suitable position, and then adjust the position of the hanger 5 through the hydraulic support structure 1, and then control the winch structure 2 to release the belt 3, so that the hanger 5 descends, and at this time, the two groups of hydraulic milling wheels 6 under the hanger 5 work to groove the ground.

[0027] In the embodiment of the utility model, a driving frame structure 7 is arranged on the top of the base 10, and two groups of symmetrical triangular limit frames 8 are arranged on the top of the driving frame structure 7, and welding strips 9 are arranged on the sides of the opposite sides of the two groups of triangular limit frames 8, and limiting grooves 501 corresponding to the welding strips 9 are opened on both sides of the hanger 5. After the hanger 5 is placed, the positions of the two groups of triangular limit frames 8 can be synchronously adjusted by the driving frame structure 7, so that the welding strips 9 on the two groups of triangular limit frames 8 are directly inserted into the limiting grooves 501 of the hanger 5, thereby limiting the hanger 5, so that the hanger 5 can only be lifted and lowered in the vertical direction. Therefore, when the hydraulic milling wheel 6 encounters hard objects such as stones during the grooving process, the hanger 5 will only move in the vertical direction during the vibration and rebound process, and no deflection will occur, thereby ensuring the verticality of the subsequent grooving of the hydraulic milling wheel 6 on the hanger 5 to avoid deviation.

[0028] Specifically, the driving frame structure 7 includes two groups of mounting bars 701, and the two groups of mounting bars 701 are slidably arranged on the base 10. Two groups of symmetrical first hydraulic cylinders 702 are arranged between the two groups of mounting bars 701. The cylinder body of the first hydraulic cylinder 702 is connected to the base 10, and the piston end of the first hydraulic cylinder 702 is connected to the mounting bar 701. The first hydraulic cylinder 702 can drive the two groups of mounting bars 701 to move their positions, thereby realizing the position adjustment of the triangular limit frames 8 on the two groups of mounting bars 701, so that the welding strips 9 on the triangular limit frames 8 are inserted into the limit grooves 501 of the hanger 5.

[0029] Furthermore, a second hydraulic cylinder 703 is arranged on the back sides of the two groups of mounting strips 701, and the piston end of the second hydraulic cylinder 703 is connected to the triangular limit frame 8 through a connecting block. The second hydraulic cylinder 703 can push the triangular limit frame 8 on the two groups of mounting strips 701 forward so that the welding strip 9 on the triangular limit frame 8 is aligned with the limit groove 501 of the hanger 5.

[0030] Furthermore, a T-shaped opening groove 704 is provided at the top of the mounting bar 701, and both ends of the opening groove 704 are open. A T-shaped sliding bar 801 is arranged at the bottom of the triangular limit frame 8, and the sliding bar 801 is located in the opening groove 704. With the cooperation of the T-shaped opening groove 704 and the T-shaped sliding bar 801, the triangular limit frame 8 can slide on the mounting bar 701.

[0031] It is worth mentioning that two groups of second slide grooves 1001 symmetrical to the mounting strip 701 are provided on the top of the base 10, and a second slider 1002 is slidably arranged inside the second slide groove 1001, and the second slider 1002 is connected to the mounting strip 701. With the cooperation of the second slide groove 1001 and the second slider 1002, the sliding installation of the two groups of mounting strips 701 is realized.

[0032] In the embodiment of the utility model, a rectangular through hole 901 is provided on the side of the welding strip 9, two groups of buckling strips 902 are slidably arranged inside the rectangular through hole 901, and a plurality of groups of springs 903 are arranged between the two groups of buckling strips 902. The buckling strip 902 is inclined toward one side of the hanger 5, and a matching groove 502 symmetrical to the buckling strip 902 is provided inside the limiting groove 501. When the welding strip 9 enters the limiting groove 501, the buckling strip 902 will retract to the rectangular through hole 901 under the cooperation of its inclined surface and the limiting groove 501. At this time, the spring 903 is in a compressed state. When the welding strip 9 is completed After being fully inserted into the limiting groove 501, at this time, under the reset of the spring 903, the snap-fit ​​strip 902 will be ejected, and the snap-fit ​​strip 902 will extend into the matching groove 502. At this time, the flat side of the snap-fit ​​strip 902 will be pressed against the side wall of the matching groove 502, so that the two groups of triangular limiting frames 8 and the hanger 5 are combined to form an integral structure, which can greatly ensure the stability between the three, making the two groups of triangular limiting frames 8 not easy to deform, thereby better ensuring the limiting stability of the two groups of triangular limiting frames 8 on the hanger 5, and using this method, the welding strip 9 can be directly connected with it from the side of the hanger 5, which is convenient for the connection operation between the two.

[0033] Specifically, the two side walls inside the rectangular through hole 901 are provided with a first sliding groove 904, and two groups of first sliding blocks 905 are slidably arranged inside the first sliding groove 904. The first sliding blocks 905 are connected to the corresponding buckling strips 902. With the cooperation of the first sliding grooves 904 and the first sliding blocks 905, the sliding installation of the buckling strips 902 is realized, which has a limiting effect and prevents the buckling strips 902 from detaching from the rectangular through hole 901.

[0034] Working principle: This embodiment provides a hydraulic double-wheel slot milling machine. First, when slotting the ground, the personnel can move the device to a suitable position, and then adjust the position of the hanger 5 through the hydraulic support structure 1, and then control the winch structure 2 to release the belt 3, so that the hanger 5 descends. At this time, the two sets of hydraulic milling wheels 6 under the hanger 5 work to slot the ground;

[0035] Secondly, after the hanger 5 is positioned, the positions of the two sets of triangular limit frames 8 can be synchronously adjusted through the driving frame structure 7, so that the welding strips 9 on the two sets of triangular limit frames 8 are directly inserted into the limit grooves 501 of the hanger 5, thereby limiting the hanger 5, so that the hanger 5 can only be lifted and lowered in the vertical direction. Therefore, when the hydraulic milling wheel 6 encounters hard objects such as stones during the grooving process, the hanger 5 will only move in the vertical direction during the vibration rebound process, and will not deflect, thereby ensuring the verticality of the subsequent grooving of the hydraulic milling wheel 6 on the hanger 5 and avoiding deviation.

[0036] Finally, in the process of the welding strip 9 entering the limiting groove 501, the buckling strip 902 will retract to the rectangular through hole 901 under the cooperation of its inclined surface and the limiting groove 501. At this time, the spring 903 is in a compressed state. When the welding strip 9 is fully inserted into the limiting groove 501, the buckling strip 902 will be ejected under the reset of the spring 903, and the buckling strip 902 will extend into the matching groove 502. At this time, the plane side of the buckling strip 902 will be pressed against the side wall of the matching groove 502, so that the two groups of triangular limiting frames 8 and the hanger 5 are combined to form an integral structure, which can greatly ensure the stability between the three, making the two groups of triangular limiting frames 8 not easy to deform, thereby better ensuring the limiting stability of the two groups of triangular limiting frames 8 on the hanger 5. In addition, in this way, the welding strip 9 can be directly connected with the hanger 5 from the side, which is convenient for the connection operation between the two.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
