Description
Technical Field
The invention relates to the field of buffer braking devices, in particular to the field of anti-overturning synchronous buffer braking devices for large-stroke and large-area moving objects.
Background
In some impact and impact tests, the installation tool is required to carry the tested piece to complete the impact and impact tests at a specific speed downwards so as to realize the evaluation of the performance of the tested piece. In the test, after the installation tool carries the measured piece to complete the impact or the impact at a certain speed, the installation tool carries the residual measured piece to dive downwards at a certain speed, if the installation tool does not adopt buffer braking, the installation tool can instantly digest kinetic energy in a collision mode, and the damage to the installation tool is huge. In addition, if the area of the measured piece is large, the installation tool is also a large-area mechanism, and if the buffering action of a plurality of buffering points is asynchronous, the overturning of the installation tool is likely to be caused, and other devices are even damaged. In view of the application background, the invention provides a large-stroke anti-overturning synchronous buffer braking device. The large-stroke buffering greatly reduces the damage to the installation tool and the residual tested piece due to the instant buffering force. Synchronous buffering can reduce the unbalanced force that installation frock received in the process of dive decline buffering, has reduced the probability of tumbling of installation frock. The anti-tipping is a guide mechanism which is reasonably designed on the installation tool, can move along a preset path even if the installation tool is acted by unbalanced force, and has certain anti-tipping and anti-unbalance loading capacity.
Disclosure of Invention
In view of the above problems, the invention aims to provide a large-stroke anti-tipping synchronous buffer brake device, wherein four buffer springs, four buffer slide blocks and four guide rail cylinders which are symmetrically distributed are adopted to form a spring and a friction buffer device, so that four buffer points are provided for an installation tool. The four springs are of the same specification and length, and in the process of diving and descending of the installation tool, if the installation tool does not roll over, the extension amount of each spring is the same, and the buffering forces of the springs are all the same. Meanwhile, the shaft-clasping type friction braking device is arranged in the buffer sliding block, the friction force between the shaft-clasping friction plate and the guide rail cylinder can be adjusted by adjusting the pretightening force of the compression screw, and the same friction buffering braking force at each position can be ensured by adjusting the compression screw of each buffer sliding block to the same pretightening force. Under the specific diving descending speed of the installation tool, the spring stiffness and the pre-compression force of the compression screw determine the buffer stroke, so that large-stroke buffer can be provided for the installation tool, and the damage of instant impact force to the installation tool is avoided. Four polyurethane buffers and four oil pressure buffers which are symmetrically distributed are adopted on the base, so that the phenomenon that the installation tool is dived to the lowest position to directly collide with the base is avoided. The oil buffer is higher than the polyurethane buffer, the buffer force of the second buffer oil buffer is determined by the contact speed of the installation tool and the oil buffer, the higher the speed is, the higher the buffer force is, and the lower the speed of the installation tool after the installation tool is buffered by a spring, so the buffer force of the oil buffer to the installation tool cannot damage the installation tool. The roller mechanisms which are symmetrically distributed are adopted at four corners of the installation tool, and the guide rails on the support columns form rolling pairs, so that the condition that the installation tool is subjected to unbalance loading to tip over in the process of turning, diving and descending due to large and uneven friction force is avoided by adopting the rolling pairs. In addition, each corner of the installation tool is provided with an upper roller mechanism and a lower roller mechanism, and a certain distance is reserved between the upper roller mechanism and the lower roller mechanism, so that the guidance between the roller mechanisms and the guide rail can be enhanced, and the unbalance loading resistance and the tipping resistance of the installation tool during vertical movement are improved.
In order to achieve the purpose, the invention provides a large-stroke anti-tipping synchronous buffer braking device, which comprises: the base, the support column, the top platform, spring upper end fixing base, a spring, guide rail cylinder upper end fixing base, guide rail cylinder upper end cushion rubber, buffering slider casing, the guide rail cylinder, guide rail cylinder lower extreme cushion rubber, guide rail cylinder lower extreme fixing base, the bottom buffer mount pad, the polyurethane buffer, the hydraulic buffer, the installation frock, spring tip set screw, buffering slider end cover, buffering slider top cushion rubber, friction disc pre-compression adjusting screw, cylindricality clamp plate one, the friction disc, cylindricality clamp plate two, the gyro wheel mounting bracket, gyro wheel pivot round pin axle, upside roller train installation transition piece, the gyro wheel guide rail. The spring, the upper end fixing seat of the spring, the fixing screw at the end part of the spring, the shell of the buffer sliding block, the upper end fixing seat of the guide rail cylinder, the lower end fixing seat of the guide rail cylinder, the buffer rubber at the upper end of the guide rail cylinder, the buffer rubber at the lower end of the guide rail cylinder, the end cover of the buffer sliding block, the first cylindrical pressing plate, the second cylindrical pressing plate, the friction plate and the pre-compression force adjusting screw of the friction plate jointly form a spring buffer and friction buffer braking device, and the spring buffer and friction buffer braking device can provide buffer braking with large stroke for an installation tool; the roller, the roller mounting frame, the roller rotating shaft pin shaft, the upper side roller group mounting transition piece, the roller guide rail and the like form a rolling pair for vertical movement of the mounting tool, so that the anti-tilting capability of the vertical movement of the mounting tool is enhanced; the bottom buffer device mounting seat, the polyurethane buffer and the oil pressure buffer form a ground buffer device, and the installation tool is prevented from directly colliding with the base.
Spring buffering and friction disc buffer brake provide the buffer brake of big stroke for installing the frock. When the installation frock dives downwards with a certain speed, the ann changes the frock and produces the effort through buffering slider top cushion rubber and buffering slider, and the use of this rubber has cushioned installation frock and four buffering slider's contact collision. Because the installation tool does not tip over, the installation tool and the four buffering sliding blocks simultaneously generate acting force, the four buffering sliding blocks and the installation tool descend together under the action of the speed and inertia of the installation tool, the descending speed is consistent, and the synchronization of the buffering force of the spring is ensured. Along with the decline of installation frock, spring elongation constantly increases, and the cushion effect who provides also increases thereupon, and installation frock speed reduces gradually. In addition to the fact that the spring converts the kinetic energy into elastic potential energy, the friction plate in the buffering slide block also consumes a part of the kinetic energy through friction. The pre-pressing force screws of the friction plates of the buffer sliding blocks are required to be adjusted through a torque wrench so as to ensure that the friction forces of the buffer sliding blocks are consistent. The friction plate not only consumes kinetic energy, but also provides a buffer braking effect for the spring storing elastic potential energy, and prevents the tension spring from pulling the installation tool to move upwards greatly (the tension force after the tension of the spring is offset, and the rebound of the installation tool when the spring is pulled is avoided).
In order to ensure that the installation tool can smoothly rotate and vertically move and provide the vertical movement guide function for the installation tool, a rolling pair is formed by a rolling wheel mechanism and a guide rail. The adoption of the rolling pair greatly reduces the resistance of the vertical movement of the installation tool. Meanwhile, the rolling pairs are symmetrically distributed relative to the installation tool, an upper group of rolling wheel mechanisms and a lower group of rolling wheel mechanisms are adopted at each position, each group of rolling wheel mechanisms comprises 3 rolling wheels, and 3 rolling pairs are formed by the rolling wheels and three surfaces of the guide rail respectively, and the upper group of rolling wheels and the lower group of rolling wheels are separated by a certain distance.
In order to prevent the tool from directly colliding with the base due to high installation speed, a polyurethane buffer and an oil buffer are arranged on the base besides the buffer brake of the spring and the friction plate. When the installation tool is about to reach the surface of the base, the installation tool is firstly contacted with the hydraulic buffer, the buffer force provided by the hydraulic buffer is larger when the relative speed is larger, and the speed of the installation tool is reduced to be small through the action of the spring and the friction plate when the installation tool is about to reach the surface of the base, so the acting force between the installation tool and the hydraulic buffer is also smaller. If the installation tool continuously descends after contacting the oil buffer, the installation tool can contact the polyurethane buffer, and collision contact between the installation tool and the base is avoided.
The spring and friction plate combination provides a solution for large-stroke synchronous buffer braking of a large-stroke and large-area moving object, and the design of the roller set mechanism reduces the movement resistance of the moving object and provides the guiding and anti-overturning capabilities.
Preferably, the contact surfaces of the moving object (installation tool) and the buffer slide block, the oil buffer and the polyurethane buffer are provided with buffer rubber, so that the direct interaction of hard objects is avoided;
preferably, the cylindrical pressing plate in the buffering slide block is designed and processed by adopting a metal material with higher rigidity and strength, so that pre-compression force is conveniently and uniformly transmitted to the friction plate;
preferably, the upper and lower roller mechanisms of the roller group need to have a certain distance in the vertical direction to enhance the anti-tipping capability;
preferably, the roller can be made of a non-metallic material with high strength, so that direct action between metal and metal is avoided, and noise can be reduced;
preferably, all the rollers and the guide rail should keep a good contact state, and can be adjusted by adding a gasket to ensure effective contact of all the rollers and the guide rail;
preferably, the spring, the friction plate, the polyurethane buffer and the oil pressure buffer device at each position are kept consistent, so that the consistent buffering condition is ensured;
the invention relates to a large-stroke anti-overturning synchronous buffer device, which adopts a spring and a friction plate to provide buffer braking force for a moving installation tool. The spring is pulled to provide tension in the opposite direction for the moving installation tool, the friction plate and the cylindrical guide rail form a friction pair through the pressing mechanism to provide friction in the opposite direction for the moving installation tool, the tension and the friction provide buffering brake force for the moving installation tool together, and large stroke buffering can be realized, so that huge collision impact force caused by short-distance buffering is avoided. The roller train mechanism is adopted on the up-down moving pair of the installation tool, and the roller train mechanism and the guide rail form a rolling pair, so that the smoothness of vertical movement of the installation tool is enhanced. Meanwhile, the roller group mechanism is provided with two groups of rollers which have a certain distance in the vertical direction, so that the guidance of the up-down moving pair is enhanced, and the anti-tipping capability of the up-down moving pair is improved.
