Description

 The invention relates to mechanization of dismantling pipelines with a bell-type connection and can be used in sets of field main pipelines with increased productivity.

 Known mounting tool containing a mounting wrench, detachable sleeve, mounting hook and lever-stand / 1 /. However, the use of this tool makes it possible only to manually disassemble the pipe connection due to the high labor costs and the low rate of work.

 The closest technical solution, selected as a prototype is a device for mounting a pipeline, consisting of a carriage and a pipe feed mechanism / 2 /. However, the design of the device does not provide for the function of dismantling the linear part of the pipeline.

 The present invention solves the problem of machine dismantling of the linear part of the pipeline with pipe joints of the type "bell", reduce time and reduce the complexity of operations.

 This problem is solved by installing along the sides of the carriage rails rigidly connected to the frame, and on the carriage - a detachable mechanism that includes sprocket gears that mesh with the racks in the rearward position of the carriage and connected by chains and rods with detachable half-sleeves that rotate on levers pivotally connected to the frame, and also due to the installation of a shock-passing mechanism in front of the carriage, which has the possibility of axial movement and pivotally connected to the rod of the pipe feed mechanism, made o in the form of a housing on which grippers with springs and a beam equipped with damper springs are mounted, pivotally connected to the upper and lower rods with pushers.

These signs are essential for solving the task as:
1. Gears-sprockets mounted on the carriage and connected to detachable half-bushings by means of chains and rods, having the possibility of engaging with racks rigidly connected to the frame, in the rearward position of the carriage receive rotational movement and pull the chains. This achieves the introduction of detachable half-sleeves in the socket and the extraction of the steel locking ring.

 2. The shock-through mechanism, placed in front of the carriage with the possibility of axial movement, when struck by its grips on the socket with the pressed locking ring, has a speed twice the speed of the disassembled pipeline line. This allows the cuff to exit the socket and complete the dismantling of the connection.

 Analysis of the claimed invention with the prototype is shown in the table.

 Comparative analysis with the prototype showed that the claimed device differs from the known one in that in order to ensure the dismantling of the linear part of the pipeline, the carriage further comprises a detachable mechanism that includes pinion gears engaged with the racks in the rearward position of the carriage and connected by chains and rods with detachable half-sleeves turning on levers pivotally connected to a frame on which the rails are rigidly mounted along the sides of the carriage, and an impact-through mechanism mounted in front of the carriage with the possibility of axial movement and pivotally connected to the draft of the pipe feed mechanism, made in the form of a housing on which grippers with springs and a beam are mounted, equipped with damper springs, pivotally connected to the upper and lower rods with pushers, and thus meet the criterion "novelty".

 An analysis of the known technical solutions in the study area allows us to conclude that they lack features similar to the significant distinguishing features in the claimed technical solution, and to recognize the claimed technical solution that meets the criterion of "significant differences".

 In FIG. 1 is a kinematic diagram of a device for dismantling a pipeline; in FIG. 2 - detachable mechanism; figure 3 - shock-throughput mechanism.

 The proposed device includes a carriage 1 and a pipe feeding mechanism 2, interconnected by a beam 3, with damper springs 4, and mounted on a frame. Along the sides of the carriage there are rails 5, rigidly connected to the frame. A detachable mechanism 6 is mounted on the carriage, consisting of gears-sprockets 7 that mesh with the racks in the rearward position of the carriage and connected via chains 8 and rods 9 to detachable half-bushings 10 that rotate on levers 11 pivotally connected to the frame and shock a passage mechanism located in front of the carriage with the possibility of axial movement and pivotally connected to the rod 12 of the pipe feed mechanism, made in the form of a housing 13, on which grips 14 with springs and a beam 15 are equipped with damper zhinami 16 and pivotally connected to the lower 17 and upper 19 with pusher rods 18.

 A device for dismantling the pipeline works as follows.

 When the frame moves forward, the driving carriage 1 with its grips abuts against the socket of the connection passing through it and starts to move back with it. In this case, the thrust 9 carries along detachable half-sleeves 10, which rotate on levers 11 pivotally connected to the frame. Making rotational movements, detachable half-sleeve 10 are included in the socket. The upper chain branch of the pipe feed mechanism 2, thrown over the sprocket, when the carriage 1 moves, begins to move backward (the lower chain branch is stationary with respect to the frame). The speed of movement of the upper branch of the chain is two times higher than the relative speed of movement of the carriage 1, since the asterisk in the kinematic scheme is a moving block. When the upper branch of the chain moves backward, the thrust 12 begins to move backward, which drives the shock-passing mechanism. When the rod 12 is moved backward, the forces on the damper springs 16 increase, as a result of which the upper spring begins to work in compression, and the lower spring in tension. As a result of this, the thrust 19 begins to move back, dragging along the pushers 18, which translate the upper grip to the impact position. At the same time, the thrust 17 begins to move forward, dragging along the pushers 18, which translate the lower grip into the impact position. At the end of this process, the forces in both damper springs are equalized and the pushers assume neutral positions. When the driving carriage 1 moves backward, the gears-sprockets 7 fixed on it, pivotally connected to the chains 8 and the rods 9, mesh with the teeth of the racks 5 and, receiving a rotational movement, tighten the chains 8. As a result, the locking ring of the connection is detachable half-sleeves 10. The moment of squeezing the locking ring coincides with the moment of impact of the grippers 14 of the shock-access mechanism along the bell, while the speed of movement of the shock-passage mechanism is two times the speed of the leading carriage 1. At the moment of impact grips 14 of the funnel force at all levels of the carriage mechanism bystpo 1 increases, which leads to its compression damper springs 4 and triggering its capture mechanism that transmits freed pipe Get additional movement - back. The leading carriage 1, freed from the socket, stops at the end of its stroke. After that, the thrust 12 of the pipe feed mechanism under the action of the next feed pipe begins to move to its extreme forward position and returns all the parts to their original state. When the rod 12 is moved forward, forces on the damper springs 16 increase, as a result of which the upper spring begins to work in tension, and the lower spring in compression. As a result of this, the thrusts 17 and 19, entraining the pushers 18, translate the grippers 14 into the pipe passage position.
