Description

Technical Field

[0001] This utility model relates to the field of tunneling machine technology, specifically to an anti-backward buffer support device for an intelligent vibratory shield tunneling machine. Background Technology

[0002] Shield tunneling machines, also known as tunneling machines, are widely used in underground space construction and building. They use a vibrator on the crushing mechanism to drive the bucket teeth to vibrate and impact the surface of objects to achieve the crushing function. During crushing operations, the reaction force generated by the crushing mechanism impacting the object is fed back to the shield tunneling machine, causing it to retreat or shift, which in turn affects the crushing accuracy, crushing efficiency, and stability of the shield tunneling machine itself. Utility Model Content

[0003] The purpose of this utility model is to provide an intelligent anti-backward buffer support device for a vibrating shield rock machine, in order to solve the problem that existing shield rock machines are easily displaced by impact during use, which affects the crushing accuracy, crushing efficiency and the stability of the shield rock machine itself.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an anti-backward buffer support device for an intelligent vibratory shield rock machine, comprising:

[0005] The hinge seat is located at the bottom of the rear end of the shield rock machine, and several sets of first through holes are arranged opposite each other on the plates on both sides of it.

[0006] The support leg has at least one set of second through holes on its two sides, and the upper end of the support leg is hinged to one set of first through holes.

[0007] The telescopic drive device has one end hinged to another set of the first through holes, and the outer end of the output shaft at the other end hinged to the second through hole.

[0008] As a further description of the above technical solution:

[0009] The top of the support leg is provided with a first hinge lug. The plates on both sides of the hinge seat are fitted onto the first hinge lug and abut against the end face of the first hinge lug through the first convex ring. The protrusions at both ends of the first hinge lug rotatably pass through the first convex ring and the first through hole.

[0010] As a further description of the above technical solution:

[0011] The support leg has a V-shaped structure, and the distance between the two side plates gradually decreases from bottom to top.

[0012] As a further description of the above technical solution:

[0013] Several anchor blocks with pointed bottoms are provided on the bottom surface of the support leg.

[0014] As a further description of the above technical solution:

[0015] One end of the telescopic drive device is provided with a second hinge ear. The plates on both sides of the hinge seat are fitted onto the second hinge ear and abut against the end face of the second hinge ear through the second convex ring. The protrusions at both ends of the second hinge ear can rotatably pass through the second convex ring and the first through hole.

[0016] As a further description of the above technical solution:

[0017] The outer end of the output shaft is provided with a third hinge lug. The plates on both sides of the support are fitted onto the third hinge lug and abut against the end face of the third hinge lug through a third convex ring. The protrusions at both ends of the third hinge lug rotatably pass through the third convex ring and the second through hole.

[0018] In summary, by adopting the above technical solution, this utility model has the following advantages over the prior art:

[0019] Beneficial effects:

[0020] When using the anti-backward buffer support device of this intelligent vibratory shield rock crusher, before the crushing operation, the output shaft is driven to extend from the telescopic drive device and push the outriggers, causing the outriggers to rotate downward relative to the hinge seat and abut against the ground. The anchor block is inserted into the ground, achieving stable anchoring, support, positioning, and impact buffering of the shield rock crusher to the ground. This prevents the reaction force generated by the breaker hammer impacting the surface of the target material during operation from causing the shield rock crusher to backward or shake, thereby ensuring the accuracy, efficiency, and overall stability of the crushing operation. The end-hinged, adjustable triangular structure formed by the hinge seat, outriggers, and telescopic drive device improves its structural strength and the stability of support and positioning between the shield rock crusher and the ground.

Therefore, they should not be construed as limitations on this utility model.

[0029] Please see Figure 1-3 This utility model provides a technical solution: an anti-backward buffer support device for an intelligent vibratory shield rock machine, comprising:

[0030] The hinge seat 1 is located at the bottom of the rear end of the shield rock machine, and several sets of first through holes 2 are arranged opposite each other on the plates on both sides of it.

[0031] The support leg 3 has at least one set of second through holes 4 on its two sides, and the upper end of the support leg 3 is hinged to one set of first through holes 2.

[0032] The telescopic drive device 5 has one end hinged to another set of the first through holes 2, and the outer end of its output shaft 6 is hinged to the second through hole 4. The telescopic drive device 5 is a hydraulic cylinder, pneumatic cylinder, electric cylinder, or other conventional linear drive device or mechanism.

[0033] The top of the support leg 3 is provided with a first hinge ear 8. The plates on both sides of the hinge seat 1 are fitted onto the first hinge ear 8 and abut against the end face of the first hinge ear 8 through the first convex ring 7. The protrusions at both ends of the first hinge ear 8 rotatably pass through the first convex ring 7 and the first through hole 2. One end of the telescopic drive device 5 is provided with a second hinge ear 11. The plates on both sides of the hinge seat 1 are fitted onto the second hinge ear 11 and abut against the end face of the second hinge ear 11 through the second convex ring 10. The protrusions at both ends of the second hinge ear 11 rotatably pass through the second convex ring 10 and the first through hole 2. The outer end of the output shaft 6 is provided with a third hinge ear 13. The plates on both sides of the support leg 3 are fitted onto the third hinge ear 13 and abut against the end face of the third hinge ear 13 through the third convex ring 12. The protrusions at both ends of the third hinge ear 13 rotatably pass through the third convex ring 12 and the second through hole 4. This improves the hinge stability of the triangular structure formed by the hinge seat 1, the support leg 3, and the telescopic drive device 5.

[0034] The support leg 3 has a V-shaped structure, and the distance between the two side plates gradually decreases from bottom to top, thereby ensuring stable support between the bottom of the support leg 3 and the bottom surface, while improving the buffer performance of the structure.

[0035] Several anchor blocks 9 with pointed bottoms are provided on the bottom surface of the support leg 3 to improve the positioning strength between the support leg 3 and the ground.

[0036] The working principle of the anti-backward buffer support device of the intelligent vibratory shield rock crusher in this embodiment includes: when in use, before the shield rock crusher performs crushing operations, the output shaft 6 is driven to extend from the telescopic drive device 5 and push the support leg 3, so that the support leg 3 rotates downward relative to the hinge seat 1 and abuts against the ground. The anchor block 9 is inserted into the ground to achieve stable anchoring, support, positioning and impact buffering of the shield rock crusher with the ground, so as to prevent the reaction force generated by the breaker hammer impacting the surface of the target crushing material during operation from causing the shield rock crusher to backward and shake, thereby ensuring the crushing operation accuracy, operation efficiency and the overall stability of the shield rock crusher.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
