The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

in order to realize an automatic operation line for following the root of a columnar workpiece (such as a drill rod, a drill collar, a casing and the like) so as to carry out maintenance operation, in some embodiments, the workpiece 1 is positioned on a frame body, the frame body comprises a rack 2 and a plurality of stand columns for supporting the rack, the rack is composed of a plurality of columnar steel arranged in parallel, the plurality of stand columns are divided into a first stand column 3 and a second stand column 4, the rack 2 is positioned between the first stand column 3 and the second stand column 4, the rack 2 is arranged in an inclined manner, the high end part of the rack 2 is fixedly connected with the first stand column 3, the low end part of the rack 2 is fixedly connected with the second stand column 4, and the upper part of the second stand column 4 is provided with a pile blocking part 41; the cylindrical workpiece rolls from the high end of the stand to the low end and strikes the stop portion 41, see fig. 1.

The table frame 2 has a gradient of 1.5-2 degrees, the design of the gradient utilizes the rolling potential energy of the workpiece in the state of the gradient to roll freely from a high position to a low position to form a root following pattern, and the situation that the previous workpiece is extruded to roll towards the position of an axis where the lathe is located is always kept. Namely, the slope has the function of enabling each columnar workpiece placed on the rack to freely roll from a high end to a low end, forming a continuous, orderly and combined interactive workpiece updating automation mode, adjusting the coaxiality, the axis position and the orderly and root-by-root input state which are necessary when the workpiece is maintained in the car repairing operation (the coaxiality and concentric line position automatic lifting adjusting device 'drilling tool car repairing transmission roller way synchronous lifting device' contained in the operation automation line is disclosed in CN201621013209.2 and is not described any more), and forming a complete automatic conveying system matched in the whole process.

Because the contact of the spiral groove edge structure on the surface of the workpiece 1 and the column-shaped steel of the rack has the phenomenon of stable support at two points, the workpiece cannot roll freely well, and the automatic conveying process is stopped, the contact mode of free rolling is solved first.

In order to solve the problem, in some embodiments, a two-point stable supporting contact mode formed by overlapping the spiral groove edge surface of the workpiece and the cross-shaped steel of the rack column is changed into a plane plate spiral line contact mode, and the workpiece always has a free rolling tendency.

Specifically, a plane plate 5 can be fixed on each column-shaped steel of the rack, the plane plate is made of steel, auxiliary supporting ribs for supporting the plane plate are added on two sides of the column-shaped steel to form a triangular stress support structure, the parallelism of the two corresponding plane plates is corrected, the installation is stable, the situation that each stress point is changed and is generated by the contact of the rotation change of a spiral line formed by the rolling of spiral groove edges is not inclined is guaranteed, and the plane rack and the rack keep a rigid rack body to form a plane rack, which is shown in figure 10.

In other words, in this embodiment, the spiral edge of the spiral groove edge of the workpiece always keeps single-point or linear contact with the plane plate of the plane table frame, and the overlapping portion of the rolling spiral track line is concentrated in the range of the plane plate with relative width, so that the workpiece can be kept to have the tendency of free rolling, and an automatic conveying system is formed.

When the shape, mass or strangeness of the workpiece is large, the contact surfaces, particularly the pressing points of the edges, between the workpieces and the plane plate are large, the friction force is increased, the mechanical force of the workpiece picking and overturning adjuster is limited (the related structure of the workpiece picking and overturning adjuster is disclosed in cn201520578378.x and is not described any more), and a normal automatic input pattern cannot be formed. In order to realize the automatic process, the workpieces need to be separated and discharged, and the friction is reduced. In the prior art, most of separation methods randomly pick up small stones and other objects from the ground and place the small stones and other objects into a grinding gap between a workpiece and a rack to form rolling and sliding blockage prevention. The operation method is easy to form the rolling compaction on the fingers (the thumb, the ten fingers and the middle finger), so that the disabled accidents are caused, and the operation has high-risk safety risks.

when a workpiece needs to be inserted into the rack for urgent processing, the original sequenced workpieces on the rack are rolled (or hung) to the high end by manpower, and limited and anti-rolling and anti-sliding by small stones and the like are used at the high end, and the operation method of the pad is also easy to form the rolling of fingers (a mother finger, a ten finger and a middle finger), thereby causing the disabled accidents.

In addition, the small stones and the cambered surface are poor in placement stability and easy to fall off due to vibration, the small stones are easy to crush, the high end part of the rack is heavy, large workpieces can roll to the lower end part at any time, and the workpieces rolling fast can directly impact on a certain mechanism and parts of the lower end part. The consequences of being struck: the normal vehicle maintenance operation is interfered, and the product quality is reduced or influenced; equipment and facilities are damaged by collision; if the person stays within the rolling range, life risks can occur.

In order to solve the above problems, in some embodiments, an anti-roll safety device 6 is provided on the gantry 2, and the anti-roll safety device 6 comprises a plug 61 and a handle 62 at one end of the plug, wherein the plug 61 is designed to be a rectangular trapezoid block structure, and the plug 61 is positioned on the plane plate 5 to limit the workpiece instead of a small stone block in the prior art. When the handle is held for operation, the phenomenon that human body parts and fingers enter a high-risk rolling area can be thoroughly eliminated, and the operation is particularly carried out under the condition of wearing cotton gloves, so that humanized natural conditions that the gloves are worn for operation and the gloves cannot enter the rolling area are created.

In addition, researches show that the handle extends to a position where rolling can be avoided absolutely, the handle extends downwards 35-45 degrees and obliquely leftwards (or rightwards) 35-45 degrees to form a handle in a 'askew handle' form, and the position requirement and the viewing angle observation element of an operator are met fully, and the handle is shown in fig. 2, fig. 3 and fig. 4.

Due to the arrangement of the chock, the contact surface between a small stone block and a workpiece is large, and a plurality of supporting points are arranged, so that the stability of the chock limiting workpiece is ensured; in addition, the handle is arranged, so that the handle control point of the chock block is extended, the rolling danger zone is avoided, the operation mode is changed, the safe operation regulation is formed, and favorable or operable conditions meeting the requirement that labor protection articles need to be worn in operation are created.

The chock is small and exquisite in shape, refined in structure and strong in applicability. However, a single chock is easy to lose, and in actual operation, the chock is not prepared in advance, so that an 'urgent need' state which cannot meet the requirement of a chock pad is generated, the chock pad cannot be well adapted to natural requirements in human body operation and human habitual thinking, and a complete 'human engineering application safety system' cannot be formed. Therefore, each chock is required to have timely applicability to the whole rack at any time, place and place.

the sliding guide rod 63 is designed in the whole control range of the rack, the sliding guide rod 63 is fixedly arranged on one side of the rack column steel, during installation, a handle of each chock is connected to the sliding guide rod through chains, ropes and the like, loss is eliminated, sliding can be performed everywhere, the use is convenient, the chocks can be timely taken and applied between all areas, and the sliding guide rod has the functional characteristics of timely limiting, rolling and sliding prevention, falling prevention and loss prevention, and forms an integral framework with the rack, see fig. 5.

Furthermore, a plurality of magnetic material blocks (magnets) can be embedded into each chock, or the formed chock is manufactured by completely adopting magnetic materials, as shown in fig. 4, stronger adsorbability is generated by the magnets 64 and the plane plate 5, the stability of the chock placed on the plane plate of the plane rack is improved, and the chock is prevented from freely falling off due to the influence of vibration factors after being placed.

in some embodiments, the operating specification of the anti-roll security device is as follows:

(1) An operator firstly identifies and judges the storage form and the risk grade of a workpiece on a rack, and can implement the operation for a suitable application of the chock type anti-rolling and anti-sliding safety device; the structure of the chock type anti-rolling and anti-sliding safety device and the operation of the chock pad are suitable for preventing the rolling and the sliding of a workpiece in a flat and orderly mode, and are mainly used for preventing the rolling and the sliding of the workpiece to be processed in a slope type rack form;

(2) The operation of the chock pad can be completed by one person independently or by multiple persons in a matching way, when the operation is completed independently, the standing position of an operator needs to be close to the plane rack and has a position capable of taking the chock block, so that the operation is convenient to implement and the operator can form control over a workpiece, and when the operation is completed by multiple persons in a matching way, the operator of the chock pad can enter the rack area to take the chock block to implement the chock pad after the workpiece is stable;

(3) When anti-rolling and anti-sliding control is needed to be carried out on a workpiece and workpieces at positions of higher ends of the workpiece, under the condition that all the workpieces are not required to be pushed and rolled towards the high ends, anti-rolling and anti-sliding of the workpiece to be controlled can be independently carried out by one person, an operator only needs to enter a lower-layer space and an orientation of the arranged workpieces to take down a chock from a hook of a sliding guide rod, the chock is inserted into a small gap between the workpiece and a plane rack by holding a handle end of the chock, and the end of the chock is close to one end of the workpiece, so that the completion of the operation of a chock can be realized, and the workpiece and the workpieces at positions of higher ends of the workpiece cannot form rolling and sliding towards the lower ends.

(4) when a certain workpiece and all workpieces at the upper end above the certain workpiece need to be pushed and rolled towards the high end, the operation is recommended to be completed by multiple persons in a matched mode, if the operation is finished independently, an operator is required to perform the operation process of pushing and rolling towards the high end one by one for each workpiece, a chock can be used for implementing a chock pad after each piece of workpiece is pushed and rolled to a preset position, the chock is effectively applied in the whole range of the rack, interaction, conversion and displacement can be formed, when the positions of the chocks are not consistent, the chock blocks can be interchanged, and the more suitable chock blocks can be exchanged to meet the application requirements.

(5) the operation of the plug pad is basically essential, the whole part of the hand is always positioned below the plane rack by holding the operation handle, the position with rolling risk is avoided, no matter how the workpiece rolls, the condition of forming rolling fingers is not met, and the plug pad operation is implemented by selecting the hand close to the rack to hold the plug block, so that the operation requirement factors and the human thinking of the human body can be more met. While the other hand can be in contact with the workpiece, which is virtually unharmful, since the contact enables the operator to feel the movement and rest of the workpiece, the transmission of signals is rapid, and there is a strong command effect on the coordination response and sensitivity of the overall operation.

(6) after the stopping of the stop pad, people need to withdraw flexibly and quickly and do not need to stay in the space range where the workpieces roll to form extrusion and smashing injuries, so that the phenomenon that the workers are not concentrated in energy and roll to the lower end due to unknown reasons to cause accidental smashing injuries or more serious casualties is prevented.

(7) When the plug pad is in an uncontrollable state in operation, an operator needs to squat down quickly to enable all body parts to be hidden in a lower layer space where workpieces roll, and the mode of running towards the two ends cannot be selected to avoid possible damage caused by the workpieces in a rolling state, so that serious smashing is prevented.

(8) When the workpiece needs to be moved and the chock blocks are removed, an operator needs to squat at the lower layer space position of the workpiece rolling space to ensure that the body part is not higher than the space layer where the workpiece rolls, the chock block removal mode needs to be determined according to the rolling space and the distance of the workpiece, the workpiece cannot be in a state of rapidly rolling, and the phenomenon that the rack and facilities are damaged due to impact caused by large impact kinetic energy is prevented. And (4) selecting a slow moving and placing mode matched with multiple persons, and if the slow moving and placing mode is required to be completed independently, recommending the use of a workpiece moving and placing device, namely controlling the rolling distance to keep the workpiece in a slow rolling mode.

When the lifting hook or the sling needs to be taken out in the hoisting operation, the workpiece is placed on the slope rack unstably, a rolling and sliding limiting measure must be taken, and because personnel must enter a crack between the rack and the workpiece to take out and hang the lifting hook or the sling, the lifting hook is taken out and hung on the sling, and at the moment, the rolling and sliding prevention is realized by only using the plug block, and a plurality of hidden dangers still exist.
