Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical engineering, and particularly relates to a multi-functional mechanical head with power conversion and a conversion method thereof. Background Art

[0002] Generally, in order to complete the chiseling of local concrete, a chiseling tool can be installed on a construction machine to achieve the chiseling of concrete and the like. The chiseling tools are generally independently arranged, and generally one robotic arm is equipped with one chiseling tool. Therefore, in the face of different construction environments, it is often impossible to use a set of chiseling tools to complete all chiseling construction operations. Especially when operating in a narrow space, according to the conventional construction method, it is difficult to smoothly and conveniently achieve the frequent switching of the chiseling tools.

[0003] Therefore, how to provide a multi-functional mechanical head with power conversion and a conversion method thereof to adapt to the operation in a narrow space is a technical problem that those skilled in the art urgently need to solve.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of implication that this information is prior art well-known to those of ordinary skill in the art. Summary of the Invention

[0005] Aiming at the problem that in the chiseling construction of a narrow area in an existing narrow construction space, the frequent switching of the chiseling tool cannot be normally completed, the present invention provides a multi-functional mechanical head with power conversion and a conversion method thereof to complete the concrete chiseling operation in a narrow space.

[0006] To solve the above technical problems, the present invention includes the following technical solutions:

[0007] A multi-functional mechanical head with power conversion, comprising:

[0008] A pair of horizontally parallel top plates and bottom plates, the bottom plate is provided with a hollow cylindrical hole, and the top plate is fixedly connected to the robotic arm;

[0009] A scissors brace, a hydraulic driving mechanism is provided between the two legs of the scissors brace, the top ends of the legs are matched with the first chute on the lower surface of the top plate, and the bottom ends of the two legs are respectively matched with the second chute;

[0010] A telescopic chiseling head, at the top of the telescopic chiseling head is provided with a central turntable, and the central turntable can enter and exit the central cylindrical hole of the bottom plate under the action of a hydraulic driving mechanism; the central axis of the central turntable is fixed on the bottom plate, and at the bottom of the top plate is provided with a corner driving mechanism. On the central turntable, a pair of first fixing grooves are coaxially arranged. On both sides of the central turntable, two fixing supports are symmetrically arranged. The central turntable is clamped between the two fixing supports. In the middle of the fixing support is provided with a rotating shaft, and on the rotating shaft is provided with a second fixing groove. The first fixing groove and the second fixing groove are connected through the second sliding groove. At the bottom surface position of the second fixing groove of the rotating shaft is provided with a female locking buckle, and at the bottom surface position of the second sliding groove of the central turntable are respectively provided with connecting parts that are arranged in cooperation with the female locking buckle.

[0011] A folding mechanical shear, the folding mechanical shear includes two shear blades, and the shear blades are fixedly connected to the rotating shaft of the fixing support through a foldable bracket. Under the action of the corner driving mechanism, the central turntable rotates by a certain angle around the central axis, so that the female locking buckle and the connecting part are clamped tightly. Under the action of the hydraulic driving mechanism, the lower ends of the two legs of the shear strut are switched between the first fixing groove and the second fixing groove, thereby driving the shear blades to open and the telescopic chiseling head to retract, or the shear blades to retract and the telescopic chiseling head to extend.

[0012] Further, a notch is provided at the edge of the bottom plate. When the female locking buckle and the connecting part are clamped tightly, the foldable bracket of the shear blade just passes through the notch, so that the shear blades open.

[0013] Further, the connection method between the connecting part and the female locking buckle is C, O connection, or convex block and concave block connection.

[0014] The present invention also provides a conversion method for a multi-functional mechanical head with power conversion. Using the aforementioned multi-functional mechanical head with power conversion, the conversion method includes:

[0015] When only using the telescopic chiseling head for chiseling operations, control the hydraulic driving mechanism to make the lower ends of the two legs of the shear strut slide onto the first fixing groove, make the shear blades retract upward through the notch of the bottom plate above the bottom plate, and at the same time make the chiseling head of the telescopic chiseling head extend downward in place, then chiseling operations can be carried out;

[0016] When it is intended to replace and use the folding mechanical shear for shearing operations, control the corner drive mechanism so that the central turntable rotates by a certain angle around the central axis, causing the female lock and the connecting part to be clamped. At the same time, control the hydraulic drive mechanism so that the lower ends of the two legs of the scissors brace slide onto the second fixed groove, causing the chisel head of the telescopic chisel head to retract upward. At the same time, cause the shear blades to extend through the notch in the bottom plate and be in place, changing the folding mechanical shear from the folded state to the open state, and then shearing operations can be carried out.

[0017] Furthermore, the connection method between the connecting part and the female lock is C, O connection, or convex block and concave block connection.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] A multi-functional mechanical head with power conversion provided by the present invention integrates a telescopic chisel head and a folding mechanical shear. Moreover, under the action of the hydraulic drive mechanism, the telescopic chisel head and the folding mechanical shear can be selectively used. When one is in normal use, the other retracts. This multi-functional mechanical head is small in volume and can meet the operation requirements in narrow spaces, thus adapting to construction in narrow spaces. In particular, by arranging a pair of connecting parts on the edge of the central turntable of the bottom plate and a pair of female locks on the rotating shaft of the fixed support, by starting the corner drive device, the central turntable can be rotated by a certain angle, enabling the female lock and the connecting part to be clamped, thus facilitating the extension operation of the folding mechanical shear and ensuring the force stability of the entire system. The multi-functional mechanical head of the present invention realizes the sharing of a set of power systems between the chisel head and the mechanical shear, and power switching can be carried out between the two. This multi-functional mechanical head with power switching has a smaller volume, can adapt to narrow operation spaces, and is particularly suitable for operation scenarios that require frequent switching between chiseling and shearing functions. The power linkage between the chisel head and the mechanical shear can achieve precise positioning of the object to be sheared, such as steel bars, for precise shearing. The conversion method of this multi-functional mechanical head with power conversion is simple to operate and has good popularization value. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following further elaborates in detail on a power-convertible multi-functional mechanical head and a conversion method provided by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention. For the convenience of description, the "upper" and "lower" directions mentioned below are consistent with the upper and lower directions of the accompanying drawings, but this cannot be a limitation on the technical solution of the present invention.

[0029] Embodiment 1

[0030] The following combines Figures 1 to 6 to detail the structural composition of the power-convertible multi-functional mechanical head of the present invention.

[0031] Please refer to Figures 1 to 6 , a power-convertible multi-functional mechanical head, which is connected to a robotic arm (not shown). The multi-functional mechanical head includes:

[0032] A pair of horizontally parallel top plates 1 and bottom plates 10. The bottom plate 10 is provided with a hollow cylindrical hole, and the top plate 1 is fixedly connected to the robotic arm;

[0033] A scissor brace 4. A hydraulic drive mechanism 5 is provided between the two legs of the scissor brace 4. The top ends of the legs are matched with the first chute 6 on the lower surface of the top plate 1, and the bottom ends of the two legs are respectively matched with the second chute 7;

[0034] A telescopic chiseling head 8 is provided with a central turntable 11 at its top end. The central turntable 11 can move in and out of the central cylindrical hole of the bottom plate 10 under the action of the hydraulic driving mechanism 5. The central axis of the central turntable 11 is fixed on the bottom plate 10. A corner driving mechanism 12 is provided at the bottom of the top plate 1. A pair of first fixing grooves 13 are coaxially provided on the central turntable 11. Two fixing supports 15 are symmetrically provided on both sides of the central turntable 11. The central turntable 11 is clamped between the two fixing supports 15. A rotating shaft 16 is provided in the middle of the fixing support 15. A second fixing groove 14 is provided on the rotating shaft 16. The first fixing groove 13 and the second fixing groove 14 are connected by a second sliding groove 7. A female locking buckle 2 is provided at the position of the bottom surface of the second fixing groove 14 where the rotating shaft 16 is located. Connecting parts 3 are respectively provided at the position of the bottom surface of the second sliding groove 7 on the central turntable 11 and are arranged in cooperation with the female locking buckle 2.

[0035] A folding mechanical shear 9 includes two shear blades (not shown). The shear blades are fixedly connected to the rotating shaft 16 of the fixing support 15 through a foldable bracket. Under the action of the corner driving mechanism 12, the central turntable 11 rotates by a certain angle around the central axis, so that the female locking buckle 2 and the connecting part 3 are clamped tightly. Under the action of the hydraulic driving mechanism 5, the lower ends of the two legs are switched between the first fixing groove 13 and the second fixing groove 14, thereby driving the shear blades to open and the telescopic chiseling head 8 to retract, or the shear blades to retract and the telescopic chiseling head 8 to extend.

[0036] Specifically, the multifunctional mechanical head applicable to narrow spaces integrates a telescopic chiseling head 8 and a folding mechanical shear 9. When the folding mechanical shear 9 is not working, it shrinks in a folded state at the rear side of the telescopic chiseling head 8 and is wrapped inside the mechanical shell that fits as closely as possible to the folding robotic arm. In this way, the multifunctional mechanical head has a smaller volume and meets the requirements of operating in narrow spaces. Through a set of power systems, the switching operation between the telescopic chiseling head 8 and the folding mechanical shear 9 can be realized, meeting the operating needs that require frequent switching between the chiseling and shearing functions, and greatly improving the construction efficiency. To further adapt to operating in narrow spaces, the multifunctional mechanical head can realize the steering function without rotating the robotic arm, so as to perform precise chiseling, shearing and other operations.

[0037] In this embodiment, more preferably, a notch is provided at the edge of the bottom plate 10. When the female locking buckle 2 and the connecting part 3 are clamped tightly, the foldable bracket of the shear blade just passes through the notch, so that the shear blade opens.

[0038] In this embodiment, more preferably, the connection method between the connecting part 3 and the female locking buckle 2 is C, O connection, or convex block and concave block connection.

[0039] Please continue to refer to Figures 1 to 6, the present invention also provides a conversion method for a multi-functional mechanical head with power conversion, using the aforementioned multi-functional mechanical head with power conversion. The conversion method includes:

[0040] When only using the telescopic chiseling head 8 for chiseling operations, control the hydraulic drive mechanism 5 so that the lower ends of the two legs of the cross brace 4 slide onto the first fixed groove 13, causing the shear blades to retract upward through the notch of the bottom plate 10 above the bottom plate 10, and at the same time causing the chiseling head of the telescopic chiseling head 8 to extend downward into position, then the chiseling operation can be carried out;

[0041] When it is intended to replace and use the folding mechanical shear 9 for shearing operations, control the corner drive mechanism 12 so that the central turntable 11 rotates by a certain angle around the central axis, causing the male locking buckle 2 and the connecting portion 3 to be clamped tightly. At the same time, control the hydraulic drive mechanism 5 so that the lower ends of the two legs of the cross brace 4 slide onto the second fixed groove 14, causing the chiseling head of the telescopic chiseling head 8 to retract upward, and at the same time causing the shear blades to extend through the notch of the bottom plate 10 into position, changing the folding mechanical shear 9 from the folded state to the open state, then the shearing operation can be carried out.

[0042] The above examples are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above examples. The above-described embodiments only represent several embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent shall be subject to the appended claims.
