Description

Technical Field

[0001] The utility model belongs to the field of tunnel construction equipment, and particularly relates to a manipulator for lifting the second lining steel mesh and arch support of a tunnel. Background Technique

[0002] With the continuous development of the construction mechanization level in China, the mechanization degree of tunnel construction has been gradually improved. As an important link in tunnel construction, the initial support of the tunnel has a great impact on the construction progress and safety. During the tunnel construction process, a circular arch support made of I-beams is required to support the excavated tunnel. The arch support is the main structure of the initial support of the tunnel. The arch support is generally made of section steel or steel bars, first processed into individual components, and then installed at the construction site. The existing arch support lifting device can only lift a single arch support at a time, resulting in problems such as slow alignment of the assembled arch support and large deviation in the positioning of the arch support.

[0003] The Chinese utility model patent CN 219733420 U discloses an arch support lifting device. By clamping support channels between the front ends and the rear ends of two channel steel positioning structures, the lifting of three arch supports can be realized, thus solving the problem of only being able to lift a single arch support at a time. However, this lifting device can only lift the arch support and cannot individually adjust the installation angle of the arch support. Since most lifting devices need to be installed on a high-altitude operation platform, personnel cooperation is required during the lifting and assembling process. Changing the lifting angle of the lifting device requires overall adjustment of the operation platform. The angle adjustment of the lifting device for the arch support will cause the operation platform to tilt, which is not conducive to the standing operation of personnel, resulting in low applicability of the lifting device.

[0004] Therefore, how to propose a manipulator for lifting the second lining steel mesh and arch support of a tunnel that can individually adjust the lifting angle has become a technical problem that needs to be urgently solved by those skilled in the art. Content of the Utility Model

[0005] The purpose of the utility model is to provide a manipulator for lifting the second lining steel mesh and arch support of a tunnel. Through the setting of the swing mechanism, the lifting angle of the arch support can be individually adjusted, thus facilitating the construction of operators and improving the assembling efficiency of the arch support.

[0006] To achieve the above purpose, the utility model provides a manipulator for lifting the second lining steel mesh and arch support of a tunnel, which is installed at the top of the mechanical arm of a trolley and is used for clamping and lifting the arch support. It includes a base, a bracket, a clamping mechanism and a swing mechanism. The bracket is hinged to the base. The overall shape of the bracket is in the shape of ︹. Auxiliary support pipes perpendicular to the bracket are respectively arranged at the front and rear top ends of the bracket. The clamping mechanism is arranged between the auxiliary support pipes. One end of the swing mechanism is hinged to the base, and the other end of the swing mechanism is hinged to the bottom of the front end of the bracket.

[0007] Furthermore, the base includes a circular fixing plate and a support frame. The support frame is arranged above the circular fixing plate. The surface of the circular fixing plate is provided with a plurality of mounting holes, and the support frame is L-shaped.

[0008] Furthermore, it further includes guiding and limiting blocks which are symmetrically arranged on the left and right sides of the bracket for guiding the arch frame.

[0009] Furthermore, the clamping mechanism includes a first clamping arm, a second clamping arm, a first hinge shaft and a clamping oil cylinder. A V-shaped mounting plate is arranged at the bottom end of the bracket. Both the first clamping arm and the second clamping arm are in a shape of "2". The first clamping arm and the second clamping arm are symmetrically arranged. The interiors of the first clamping arm and the second clamping arm are hollowed out and are movably sleeved on the outside of the V-shaped mounting plate. The first clamping arm, the V-shaped mounting plate and the second clamping arm are rotationally connected through the hinge shaft. The clamping oil cylinder is arranged below the hinge shaft. One end of the clamping oil cylinder is hinged to the first clamping arm, and the other end of the clamping oil cylinder is hinged to the second clamping arm.

[0010] Furthermore, it further includes clamping jaws which are symmetrically arranged on the clamping surfaces of the first clamping arm and the second clamping arm, and the clamping jaws are hinged to the first clamping arm and the second clamping arm.

[0011] Furthermore, pipe supports are respectively arranged at the front and rear ends of the bracket, and the auxiliary support pipe is arranged on the pipe supports.

[0012] Furthermore, the swinging mechanism is a swinging oil cylinder.

[0013] The beneficial effects of the present utility model are as follows: By installing a swinging mechanism at the bottom end of the bracket, the present utility model can separately adjust the swinging angle of the bracket, so that after the clamping mechanism clamps the arch frame, the installation angle of the arch frame can be separately adjusted, which is convenient for the assembly of the arch frame and the construction of the operators. The setting of the clamping jaws makes the clamping of the arch frame more stable. Description of the Drawings

It includes a base, a bracket 2, a clamping mechanism, and a swing mechanism.

[0022] The base includes a circular fixing plate 3 and a support frame 4. The surface of the circular fixing plate 3 is provided with a number of mounting holes for the overall installation of the lifting manipulator. The support frame 4 is arranged above the circular fixing plate 3. The support frame 4 is L-shaped. The bracket 2 is hinged to the support frame 4 of the base. The overall shape of the bracket 2 is ︹-shaped. Pipe supports 5 are respectively arranged on the front and rear end faces of the bracket 2. An auxiliary support pipe 6 perpendicular to the bracket 2 is installed on the pipe support 5. For clamping multiple arches 1, when the I-beam in the middle of the arch 1 is clamped, the I-beams on both sides can be supported by the auxiliary support pipe 6.

[0023] One end of the swing mechanism is hinged to the support frame 4, and the other end of the swing mechanism is hinged to the bottom of the front end of the bracket 2. The swing mechanism in this embodiment is a swing oil cylinder 7. By arranging the swing oil cylinder 7, the swing angle of the lifting manipulator can be adjusted separately by controlling the telescopic movement of the swing oil cylinder 7, avoiding affecting the operation of the personnel on the working platform at the top of the robotic arm.

[0024] As Figure 3 shown, the clamping mechanism is arranged between the auxiliary support pipes 6. The clamping mechanism includes a first clamping arm 8, a second clamping arm 9, a hinge shaft 10 and a clamping oil cylinder 11. Both the first clamping arm 8 and the second clamping arm 9 are in a shape of "2". The first clamping arm 8 and the second clamping arm 9 are symmetrically arranged.

The first clamping arm 8, the V-shaped mounting plate 12 and the second clamping arm 9 are rotationally connected through the hinge shaft 10. The clamping oil cylinder 11 is arranged below the hinge shaft 10. One end of the clamping oil cylinder 11 is hinged to the first clamping arm 8, and the other end of the clamping oil cylinder 11 is hinged to the second clamping arm 9.

[0025] By controlling the telescopic movement of the clamping oil cylinder 11, the first clamping arm 8 and the second clamping arm 9 can be made to be in an open or clamped state, facilitating the clamping of the arch frame 1.

[0026] In order to improve the stability of clamping the arch frame 1, clamping jaws 13 are further arranged on the clamping surfaces of the first clamping arm 8 and the second clamping arm 9. The clamping jaws 13 are hinged to the first clamping arm 8 and the second clamping arm 9.

[0027] As a preferred embodiment of the present invention, it further includes guiding and limiting blocks 14. The guiding and limiting blocks 14 are symmetrically arranged on the left and right sides of the bracket 2 and are used for guiding the arch frame 1.

[0028] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
