Abstract

The present invention relates to the technical field of building demolition machines, and specifically relates to a safe building demolition machine with rotary backstop, which includes a connecting seat installed at the shearing end of the building demolition machine, a fixed shell penetrating through the connecting seat, and a rotating seat arranged at one end of the fixed shell. A rotary mechanism for driving the rotating seat is installed at the fixed shell; this safe building demolition machine with rotary backstop ensures the stability of the knocking of the shearing mechanism, reduces the wear of the bearings at the internal gear disc at the same time, prevents the mutual wear between the rotating gear and the internal gear disc on the other hand, and realizes the lubrication of the separated rotating gear under the action of the connecting piece and the lubricating mechanism. Furthermore, when the rotating gear returns to its original position, the internal gear disc is lubricated synchronously by the rotation of the rotating gear, further reducing the wear between the rotating gear and the internal gear disc, ensuring the stability of the gear transmission between the rotating gear and the internal gear disc, and thus improving the service life of the rotary mechanism.

Description

Technical Field

[0001] The present invention relates to the technical field of building demolition machines, and particularly to a safe building demolition machine with rotary backstop. Background Art

[0002] The building demolition machine applies force through a powerful robotic arm and a hydraulic system to break or remove the structural parts of a building. Its working principle is mainly based on the principles of hydraulic transmission and mechanical crushing. By controlling the movement and force of the robotic arm, precise demolition of the building is achieved.

[0003] The rotary mechanism at the shear tongs of the building demolition machine mainly consists of components such as a rotary device (including a rotary motor, a reducer, a gear assembly, etc.) and a brake. Its function is to drive the shear tongs to rotate 360 degrees to meet the demolition requirements at different angles.

[0004] The existing shear tongs on building demolition machines can not only shear and demolish the reinforced concrete of floors, but also when demolishing materials such as wooden boards, gypsum boards, and lightweight concrete on floors, the building demolition machine uses the shear tongs to strike the building to quickly destroy its structure. However, when the shear tongs strike the building, a large impact force will be exerted on the rotary device of the shear tongs, resulting in frequent friction and wear of the components (such as bearings, gears, etc.) of the shear tongs, thereby shortening its service life.

[0059] One end of the connecting tube 644 is communicated with the liquid storage tube 641. There are two transfer tubes 645, and one end of each of the two transfer tubes 645 is communicated with the connecting tube 644, and the other ends of the two transfer tubes 645 are respectively communicated with the support tube 62;

[0060] The liquid storage tube 641, the connecting tube 644, the transfer tube 645, and the support tube 62 are filled with hydraulic oil.

[0061] Please refer to Figures 9 to 11 , the fixing member 63 includes a fixing tube 631, a moving piston 632, a moving rod 633, a connecting plate 634, a first connecting rod 635, a second connecting rod 636, a first clamping plate 637, a second clamping plate 638, and a connecting spring 639.

The cavity inside the fixing tube and between the two moving pistons 632 is kept sealed;

[0062] One end of the moving rod 633 is fixedly connected to the moving piston 632, and the other end of the moving rod 633 passes through one end of the fixed tube 631 and is fixedly connected to the connecting plate 634.

In this embodiment, anti-slip patterns are provided on the sides of the first clamping plate 637 and the second clamping plate 638 that are close to each other. At the same time, the first clamping plate 637 and the second clamping plate 638 are arranged according to the shape of the internal gear disk 22, and do not affect the connection between the rotating seat 12 and the internal gear disk 22;

[0065] There are multiple connecting springs 639. The multiple connecting springs 639 are respectively sleeved outside the first connecting rod 635 and the second connecting rod 636. The two ends of the connecting spring 639 are respectively fixedly connected to the first clamping plate 637 and the second clamping plate 638;

[0066] Specific implementation process: In this embodiment, the hydraulic oil is distributed at the liquid storage pipe 641, the connecting pipe 644, the transfer pipe 645, the support pipe 62, and the two fixed pipes 631. Then, when the servo motor 23 runs, the internal gear disk 22 is driven to rotate by the rotating gear 21. When the internal gear disk 22 rotates, the rotating seat 12 is driven to rotate relative to the connecting seat 1, so as to realize the function of adjusting the position of the shearing mechanism 3 at the rotating seat 12;

[0067] The shearing mechanism 3 can shear and demolish the building according to the demolition position of the building;

[0068] At the same time, when it is necessary to knock and remove materials such as wooden boards, gypsum boards, and lightweight concrete through the shearing pliers at the shearing mechanism 3, the rotating gear 21 disengages from the inner gear plate 22, and the telescopic cylinder 643 is operated to make the pushing piston 642 move along the inside of the liquid storage tube 641. When the pushing piston 642 moves, the hydraulic oil is synchronously pushed along the connecting tube 644 to enter the transfer tube 645 respectively, and enter the fixed tube 631 respectively through the two supporting tubes 62, that is, the hydraulic oil enters the cavity formed between the two moving pistons 632 inside the fixed tube 631. At this time, the two moving pistons 632 are pushed by the hydraulic oil respectively, and the two moving pistons 632 move in opposite directions. When the moving pistons 632 move, they drive the connecting plates 634 thereon to move through the connecting rods respectively, until the first connecting rod 635 and the second connecting rod 636 respectively drive the second clamping plate 638 and the first clamping plate 637 thereon to move in opposite directions, until the inner gear disk 22 is clamped and fixed between the first clamping plate 637 and the second clamping plate 638 to prevent the inner gear disk 22 and the rotating seat 12 from rotating.

[0069] A limit ring 6351 is installed on one of the first connecting rods 635 , and a pressure sensor 6352 is installed on the limit ring 6351 ;

[0070] That is, when one side of the second clamping plate 638 is in contact with the pressure sensor 6352, the first clamping plate 637 and the second clamping plate 638 clamp and fix the inner gear disk 22, and at the same time detect the position state of the second clamping plate 638, and send the detection signal to the control, and the controller receives the model.

[0071] A connector 4 is installed inside the fixed shell 11, and the servo motor 23 is installed outside the fixed shell 11, and the output end of the servo motor 23 is connected to the rotating gear 21 through the connector 4;

[0072] See also Figures 15 to 16 The connecting member 4 includes a slide rod 41, a slide sleeve 42, a guide block 43, a connecting sleeve 44, a synchronization block 45 and a first electric push rod 46. One end of the slide rod 41 is fixedly connected to the rotating gear 21, and the other end of the slide rod 41 is slidably connected to the inside of the slide sleeve 42. There are two guide blocks 43, which are respectively fixedly mounted on the outside of the slide rod 41. The slide sleeve 42 is provided with sliding grooves at the positions corresponding to the two guide blocks 43.

[0074] The connecting sleeve 44 is rotatably sleeved on the outside of one end of the slide rod 41 through a bearing. Two synchronization blocks 45 are provided. The two synchronization blocks 45 are respectively fixedly mounted on the outside of the connecting sleeve 44. The first electric push rod 46 is fixedly mounted inside the fixed housing 11, and the output end of the first electric push rod 46 is fixedly connected to the synchronization block 45.

[0075] In this embodiment, when the output end of the servo motor 23 rotates, the output end of the servo motor 23 drives the slide rod 41 to rotate through the slide groove on the slide sleeve 42 and the two guide blocks 43 on the slide rod 41, and the slide rod 41 drives the rotating gear 21 to rotate. At this time, the rotation between the rotating gear 21 and the internal gear plate 22 is not affected.

[0076] Specific implementation process: When the shearing mechanism 3 knocks and demolishes the building, the output ends of the two first electric push rods 46 retract synchronously, so that the two guide blocks 43 drive the sliding rod 41 to move along the inside of the sliding sleeve 42 through the connecting sleeve 44 until the first electric push rod 46 stops moving, and the rotating gear 21 is completely separated from the inner gear disk 22, and the rotating gear 21 is located at the lubrication mechanism 5.

[0077] A lubricating mechanism 5 is installed inside the fixed shell 11. The connecting member 4 cooperates with the lubricating mechanism 5. While the connecting member 4 supports and connects the rotating gear 21, it also applies lubricating oil to the rotating gear 21.

[0078] The lubricating mechanism 5 includes a contact lubricating member 51, a supporting guide member 52, an oil supply hard pipe 53, and an oil supply member 54. There are multiple contact softening members, and the multiple contact lubricating members 51 are located on the fixed frame 7. The multiple contact lubricating members 51 synchronously lubricate the rotating gear 21. In this embodiment, there are preferably four contact lubricating members 51.

[0079] A through hole is provided on the fixing frame 7, and a support guide 52 is located at the through hole. The support guide 52 is used to synchronously drive multiple contact lubricating parts 51. The contact lubricating parts 51 are connected to the oil supply hard pipe 53, and the oil supply hard pipe 53 passes through the support guide 52. The oil supply part 54 is installed inside the fixed shell 11, and the oil supply part 54 is used to provide lubricating oil to the multiple oil supply hard pipes 53.

[0080] See also Figures 12 to 14 The supporting guide member 52 includes a fixed plate 521, a rotating plate 522, a connecting ear 523, a second electric push rod 524 and a rotating seat 525. The fixed plate 521 is fixedly installed at the through hole. A fixed port 5211 is provided on the fixed plate 521 at positions corresponding to the multiple contact lubricating members 51. The oil supply hard pipe 53 slides through the fixed port 5211.

[0081] The rotating disk 522 is located on a side of the rotating disk away from the rotating gear 21, and the rotating disk 522 is rotatably connected to the through hole. The rotating base 525 is rotatably connected to the fixed frame 7, and the second electric push rod 524 is fixedly mounted on the rotating base 525. The output end of the second electric push rod 524 is rotatably connected to the connecting ear 523 via a pin shaft, and the connecting ear 523 is fixedly mounted on the outer side of the rotating disk 522.

[0082] A guide opening 5221 is provided on the rotating disk 522 at a position corresponding to the fixed opening 5211 , and the guide opening 5221 is arranged in an arc shape. The oil supply hard pipe 53 slides through the guide opening 5221 .

[0083] See also Figures 13 to 14 The contact lubricating member 51 includes a moving block 511, a moving shell 512 and a contact sponge 513. The moving block 511 is slidably connected to the fixed port 5211. The oil supply hard pipe 53 passes through the moving block 511, and an anti-separation ring is installed on the outside of the oil supply hard pipe 53. The anti-separation ring is used to prevent the oil supply hard pipe 53 from separating from the guide port 5221. One end of the oil supply hard pipe 53 is connected to the moving shell 512. The contact sponge 513 is installed inside the moving shell 512, and the side of the moving shell 512 facing the rotating gear 21 is open.

[0084] Specific implementation process: After the rotating gear 21 moves between the four moving shells 512, when the controller detects that the pressure sensor 6352 sends a signal, the second electric push rod 524 starts to operate. When the second electric push rod 524 operates, its output end drives the rotating disk 522 to rotate relative to the fixed disk 521 through the connecting ear 523. When the rotating disk 522 rotates, the four arc-shaped guide ports 5221 thereon are driven to rotate synchronously. Due to the limiting effect of the fixed port 5211 on the fixed disk 521 and the limiting effect of the oil supply hard pipe 53 at the guide port 5221, the moving block 511 drives the moving shell 512 thereon to move along the rotating gear 21. At the same time, the oil supply part 54 operates. When the moving shell 512 moves along the rotating gear 21, the contact sponge 513 is wrapped around the outside of the rotating gear 21. Then, the contact sponge 513 is squeezed to apply lubricating oil to the outside of the rotating gear 21.

[0085] After the application is completed, the moving shell 512 is disengaged from the rotating gear 21. And until the shearing mechanism 3 finishes the knocking and removal, the rotating gear 21 moves to the position meshing with the internal gear disk 22. Subsequently, the two first clamping plates 637 and the second clamping plate 638 on the internal gear disk 22 are respectively disengaged from the outside of the internal gear disk 22 under the reverse elastic force of the connecting spring 639. Then, the rotating gear 21 rotates through the operation of the servo motor 23. And when the rotating gear 21 drives the internal gear disk 22 again, it synchronously lubricates the internal gear disk 22, thereby realizing the protection of the internal gear disk 22, ensuring the stable transmission between the rotating gear 21 and the internal gear disk 22, and reducing wear.

[0086] Embodiment 2

[0087] Please refer to Figures 13 to 14 , Embodiment 2 is a further supplementary description of the oil supply part 54 in Embodiment 1. Specifically, the oil supply part 54 includes an oil tank 541, an oil pump 542, an oil supply pipe 543, an annular oil guide shell 544 and an oil supply hose 545. The oil tank 541 and the oil pump 542 are both installed inside the fixed shell 11, and the input end of the oil pump 542 is connected to the oil tank 541, and the output end of the oil pump 542 is connected to the oil supply pipe 543. One end of the oil supply pipe 543 is communicated with the annular oil guide shell 544. The annular oil guide shell 544 is installed inside the fixed shell 11. There are multiple oil supply hoses 545. One ends of the multiple oil supply hoses 545 are all communicated with the oil guide shell, and the other ends of the oil supply hoses 545 are connected to the oil supply hard pipe 53;

[0088] Thus, when lubricating the rotating gear 21, through the operation of the oil pump 542, the lubricating oil is pumped into the annular oil guide shell 544. Then, through the multiple oil supply hoses 545, the lubricating oil is introduced into the oil supply hard pipe 53, enters the moving shell 512 through the oil supply hard pipe 53, and is absorbed by the contact sponge 513. Finally, since the contact sponge 513 is in close contact with the outside of the rotating gear 21, the lubricating oil entering the contact sponge 513 flows into the tooth grooves of the rotating gear 21, thereby realizing the function of fully lubricating the rotating gear 21.
