Description

Technical Field

[0001] The present application relates to the technical field of sewer pipeline construction equipment, and more particularly, to a large pipe ramming machine. Background Art

[0002] A pipe ramming machine is a construction machine specifically used for pipe excavation and installation. The pipe ramming machine is easy to operate, can be constructed in a relatively small working space, and can work to a relatively deep underground water level. Its advantages are that it does not require large-area construction and can effectively avoid ground settlement. In addition, the pipe ramming machine also has advantages such as high efficiency and low pollution.

[0003] When the pipe ramming machine works, it generally needs to rely on other machinery to hoist the pipe into the pipe ramming machine so that the clamping mechanism of the pipe ramming machine can hold the pipe tightly. When the pipe is hoisted by machinery, the pipe will shake above the clamping mechanism and cannot be aligned into the clamping mechanism. Generally, it is necessary for the staff to manually hold the pipe steady and position the pipe into the clamping mechanism manually, which is labor-consuming. During the hoisting process of the pipe, due to the heavy weight of the pipe, if it suddenly falls, it may pose a danger to the personal safety of the staff.

[0004] Therefore, it is necessary to design a large pipe ramming machine that can automatically position the pipe into the clamping mechanism. This large pipe ramming machine can save labor and avoid the danger to the personal safety of the staff caused by the accidental fall of the pipe. Summary of the Utility Model

[0005] The content part of the present application is used to briefly introduce the concepts, which will be described in detail in the following specific implementation part. The content part of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0006] In order to solve the technical problems mentioned in the above background art part, some embodiments of the present application provide a large pipe ramming machine, including:

[0007] Two support frames, the head and tail of the two support frames are fixedly connected through a connecting seat, so as to form a working area between the two support frames;

[0008] A clamping mechanism, arranged in the working area and movably connected to the support frame, including two oppositely arranged clamping rings and a connecting ring connecting the two clamping rings. One end of the two clamping rings away from the connecting ring is movably connected through a clamping oil cylinder. A circular installation opening is formed between the two clamping rings and the connecting ring for the pipe to enter;

[0009] A hinge seat, fixedly arranged on the connecting seat, with at least three and circumferentially distributed along the axis of the installation opening;

[0010] The articulated rod is rotatably arranged on the hinge seat;

[0011] The position-adjusting oil cylinder is rotatably arranged on the connecting seat. The piston rod of the position-adjusting oil cylinder is rotatably connected to the articulated rod to drive the articulated rod to rotate.

[0012] During the working process, use a crane to hoist the pipeline above the installation opening. Due to the arrangement of the hinge seat and the articulated rod, in the initial state, the position-adjusting oil cylinder is in a contracted state. At this time, the articulated rod is opened. When the pipeline descends to the position between the articulated rods, the position-adjusting oil cylinder extends to drive the articulated rod to rotate; the end of the articulated rod away from the position-adjusting oil cylinder can contact the pipeline and drive the pipeline to align with the installation opening. Under the action of the articulated rod, the pipeline continuously descends into the installation opening; it avoids the problem that the pipeline cannot be aligned with the installation opening due to the shaking of the pipeline and requires manual steadying, saves manpower, and can avoid the harm to the personal safety of the staff caused by the sudden fall of the pipeline.

[0013] Furthermore, an anti-wear wheel is rotatably arranged at the end of the articulated rod away from the position-adjusting oil cylinder.

[0014] Furthermore, an anti-collision ring is fixedly sleeved on the anti-wear wheel, and the anti-collision ring is made of rubber.

[0015] Furthermore, both ends of the connecting ring are respectively hinged to one end of two clamping rings. Connecting blocks are fixedly installed at the ends of the two clamping rings away from the connecting ring. The clamping oil cylinder is a double-headed oil cylinder, and the piston rod of the clamping oil cylinder is rotatably connected to the connecting block.

[0016] Furthermore, a mounting seat is fixedly connected to the clamping ring. A lifting oil cylinder is movably arranged on the support frame, and the piston rod of the lifting oil cylinder is movably connected to the mounting seat to drive the pipeline to lift;

[0017] A rocking cylinder is movably arranged on the support frame, and the piston rod of the rocking cylinder is movably connected to the mounting seat to drive the pipeline to shake.

[0018] Furthermore, a number of serrated portions are formed on the inner walls of the clamping ring and the connecting ring to increase the friction with the pipeline.

[0019] Furthermore, a number of step plates are arranged on the support frame.

[0020] Furthermore, a guardrail is arranged on the support frame outside the step plates.

[0021] The beneficial effects of this application are as follows:

[0022] First, it can automatically adjust the position of the pipeline into the pipeline opening, avoid the problem that it is necessary to manually steady the pipeline and push the pipeline into the pipeline opening due to the shaking of the pipeline, save manpower, and can avoid the harm to the personal safety of the staff caused by the accidental fall of the pipeline;

[0023] Second, the setting of the anti-wear wheel can reduce the friction between the pipeline and the hinge rod;

[0024] Third, the setting of the anti-collision ring can reduce the noise generated by the collision between the anti-wear wheel and the pipeline;

[0025] Fourth, the setting of the guardrail can further protect the safety of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0040] A large pipe shaking machine includes: two support frames 1, the support frames 1 are arched, the heads and tails of the two support frames 1 are fixedly connected through a connecting seat 2, so as to form a working area 3 between the two support frames 1; a clamping mechanism 4 is movably arranged in the working area 3, the clamping mechanism 4 includes two oppositely arranged clamping rings 5 and a connecting ring 6 connecting the two clamping rings 5, both ends of the connecting ring 6 are respectively hinged to one end of the two clamping rings 5, and one ends of the two clamping rings 5 far away from the connecting ring 6 are movably connected through a clamping oil cylinder 7; specifically, the clamping oil cylinder 7 is a double-headed oil cylinder, connecting blocks 8 are respectively fixedly installed at one ends of the two clamping rings 5 far away from the connecting ring 6, and the two piston rods of the clamping oil cylinder 7 are respectively rotatably connected to the two connecting blocks 8; a circular installation opening 9 is formed between the two clamping rings 5 and the connecting ring 6, after the pipe enters the installation opening 9, the clamping oil cylinder 7 can contract to clamp the pipe; a plurality of uniformly distributed serrated portions 20 are formed on the inner walls of the clamping rings 5 and the connecting ring 6, and the serrated portions 20 can increase the friction force between the clamping rings 5 and the connecting ring 6 and the pipe;

[0041] A mounting seat 10 is welded on the clamping ring 5, and two lifting cylinders 11 are movably provided on each support frame 1.
