Description

DESCRIPTION A MOBILE It relates to a mobile X-ray device that allows fixing the X-ray tube. Prior Art Nowadays, especially in hospitals, the use of mobile X-ray devices, which carry at least an is common. In these mobile X-ray devices, various mechanisms containing telescopic arms are used to ensure vertical up-down movement of imaging units such as X-ray tubes and collimators. The common aspect of these movement mechanisms used in the state of the art is to balance the moving weight with a pre-tensioned spring mechanism in order to prevent the operator from carrying it. When the system in balance is moved by the operator, the internal mechanism created by the rope, pulley and pulley system compresses or loosens the spring. As the spring tightens or loosens, the force on the spring increases or decreases. In this case, one of the pulleys in the system is designed to be conical in order to achieve the balance between the constant load carried and the spring force. The helix geometry in the conical shape in question is determined in proportion to the movement of the spring and the forces occurring on it. The most important problem identified after the mounting of the telescopic arms used in the state of the art to the mobile X-ray device is to ensure that the height of the telescopic arm from the ground is as small as possible while moving the device. The reason for this is that driving difficulties occur due to the operator not being able to see the front while driving the device. Therefore, when the mobile X-ray device is in driving condition, the maximum height of the telescopic arm above the ground should be ensured as low as possible. Another problem seen in telescopic arms in the state of the art is that the ropes that enable the movement of the mechanism through pulleys expire in the long term and have to be replaced with new ones. While the force on the rope should be as low as possible in order to have a longer rope life, a considerable amount of force is applied to the rope in the mechanisms used in the state of the art. In addition, as the conical pulleys in the state-of-the-art mechanisms that provide load balance rotate around their own axes, the rope on the conical pulley moves sideways and a deviation angle is formed in the rope lying between the conical pulley and a moving pulley. Since this deflection angle in the rope is a factor that seriously affects the rope life, the rope deflection angle should be kept as small as possible. On the other hand, due to the positions of the moving pulleys used in the mechanisms in the state of the art, the ropes extending between the conical pulley and the moving pulley have a high deflection angle and have a low lifespan. In addition to all these, in the mechanisms used in the state of the art, when the telescopic arm is in balance, the rotation movements of the rollers are prevented by a brake or an electromagnet, ensuring that the X-ray tube and collimator remain motionless. On the other hand, in case of any problem with the brakes used in the mechanisms in question, there is a high loss of labor and time in replacing the brakes since they are positioned in places within the telescopic arm that are difficult to reach from the outside. A mobile radiographic imaging apparatus is mentioned in the patent document. In the apparatus in question, a carrier column rises at the front according to the direction of movement of the chassis that forms the main body. There is a first lifting and lowering element and a second lifting and lowering element on the carrier column in question that can move in the vertical direction. The second lifting and lowering element has an almost L-shape in side view and includes at its end an X-ray emitting unit consisting of an X-ray tube and a collimator. The first lifting and lowering element can be raised and lowered along the carrier column by a guide element provided on the carrier column. The second raising and lowering element can be raised and lowered along the first lifting and lowering element by a guide element provided on the first lifting and lowering element. At the upper part of the carrier column, a winding reel is rotatably located around a shaft fixed to the upper part of the carrier column. A second wire rope is wound on the winding spool, with one end fixed to the spool and the other end to a base arranged at the lower end of the first lifting and lowering member. Therefore, when the winding spool rotates and the winding amount of the second wire rope changes relative to the winding spool, the first lifting and lowering element is raised or lowered. On the other hand, at the upper part of the first lifting and lowering member, there is a fixed pulley arranged rotatably around a carrier shaft fixed at the upper part of the first lifting and lowering member. A wire rope for the second lifting and lowering element is wound on the fixed pulley so that it is fixed from one end to the base part provided at the lower end of the carrier column and from the other end to the base part provided at the lower end of the second lifting and lowering element. For this reason, when the wire rope in question is unwound at the base due to the elevation of the first lifting and lowering element under the influence of the second wire rope, the second lifting and lowering element also rises relative to the first lifting and lowering element. In the described invention, since the distance between the moving pulleys and the conical pulleys in the movement and load balancing mechanism is quite short, the deflection angle of the rope is quite high, and the useful life of the steel rope used is quite short. In addition, in the invention explained in the document in question, the height of the carrier column from the ground has to be relatively high due to the placement of the moving pulleys between the conical pulleys and the springs with the load balancing function, and the distance between the springs and the conical pulleys is relatively high. It negatively affects the operator's ability to see the driving area clearly while moving the radiographic imaging apparatus described in the document in question on the ground. Therefore, in the state of the art, there is a need for a mobile X-ray device containing ropes that allow the operator to see the driving area easily while driving and have an increased lifetime. Brief Description of the Invention The purpose of this invention is to realize a mobile X-ray device containing ropes that allows the operator to see the driving area easily while driving and has an increased lifetime. The mobile X-ray device defined in the first claim and the claims related to this claim in order to achieve the purpose of this invention; a body, at least one wheel that allows the body to move, a fixed column fixed to the body from a first end and rising from this first end to a second end along the vertical axis, a fixed column rising from a first end along the vertical axis to a second end and fixed in the vertical direction At least one primary movable column connected to the fixed column in such a way that it can perform almost linear movement with respect to the column, rising from a first end along the vertical axis to a second end and with the primary movable column in a way that can realize almost linear movement with respect to the primary movable column and the fixed column in the vertical direction, and at least one secondary movable column connected to the fixed column, at least one , at least one secondary pulley arranged in a region close to the second end, that is, the higher end, of the primary moving column, at least two wounds wound on the primary pulleys and fixed at one end almost to the first end, that is, the lower end of the primary moving column. primary rope, at least one secondary rope fixed at one end near the first end, in other words the lower end, of the fixed column and winding over the second pulley and fixed almost to the first end, in other words the lower end, of the secondary movable column, allowing the primary ropes to circulate within it. It is arranged in the fixed column and starts to work by being triggered by the primary ropes depending on the linear movement of the primary movable column and the secondary movable column in the vertical axis, and during its operation, it carries the load resulting from at least the weight of the primary movable column, secondary movable column, X-ray tube and collimator. It contains at least one movement mechanism configured to balance; the movement mechanism; At least one first carrier table fixed to the fixed column near the second end of the fixed column, at least one second carrier table fixed to the fixed column near the first end of the fixed column, at least two primary carrier tables extending downwards on the vertical axis, starting from the two almost opposite ends of the first carrier table shaft bearing, at least one primary shaft extending almost linearly between mutual primary shaft bearings, arranged symmetrically with respect to the middle plane of the first carrier table, with a certain gap between them on the primary shaft, having some fixed diameter and some variable diameter, and Two primary pulleys adapted in the form of a conical pulley with grooves in the structure that allow the primary ropes to sit, two fixed pulleys positioned between the primary pulleys and the primary shaft bearings, two fixed pulleys fixed to the first carrier table and carried by the first carrier table, which holds the primary pulleys and fixed pulleys between the first carrier table and the first carrier table. At least one secondary shaft bearing extending almost parallel to the first carrier table so that there is a gap that allows the bearing to be mounted, and at least one secondary shaft bearing extending almost parallel to the second carrier table and arranged in a way that there is a gap between it and the second carrier table on the side of the second carrier table facing the second end of the fixed column. At least one primary spring bearing, at least one secondary shaft extending vertically by being placed on the secondary shaft bearing at one end and on the second carrier table at the other end, and at least one secondary shaft extending vertically, bearing on the secondary shaft bearing at one end and on the primary spring bearing at the other end, surrounding the secondary shaft. At least one pressure spring extending between the shaft bearing and the primary spring bearing, at least two movable pulley carriers arranged near the opposite ends of the primary spring bearing and positioned on the said movable pulley carriers, connected to the primary ropes and immediately moving in the vertical direction with the effect of the force carried on the primary ropes. It contains moving rollers configured to immediately perform linear movement and allow the pressure spring to compress or loosen depending on the direction of this linear movement. When a vertical force is applied by the operator on the primary moving column or the second moving column, the movement mechanism starts to work. An example study regarding the movement mechanism is as follows. When a certain magnitude of downward force on the vertical axis is applied by the operator to the secondary movable column, which is in the highest position relative to the ground, the secondary rope starts to move, allowing both the secondary movable column and the primary movable column to start lowering simultaneously. As the primary movable column begins to descend, the primary ropes connected to the primary movable column from one end also move downwards on the vertical axis. As a result of the movement of the primary ropes, the primary pulleys begin to rotate around the primary shaft in a predetermined first rotation direction, such as counterclockwise. As a result of the rotation movement of the primary pulleys in the direction of primary rotation, the parts of the primary ropes wrapped around the fixed diameter part of the primary pulleys come loose and move towards the body simultaneously with the movement of the primary moving column. Before the operator applies force on the secondary movable column, in other words, when the secondary movable column is in its highest position, the parts of the primary ropes coming out of the pressure spring are located in the grooves located in the large diameter part of the primary pulleys. As a result of the downward movement of the secondary moving column and therefore the primary moving column and the rotational movement of the primary pulleys in the direction of the primary rotation, the parts of the primary ropes coming out of the pressure spring are wrapped in the grooves located on the variable diameter part of the primary pulleys. As the parts of the primary ropes coming out of the pressure spring are wound on the variable diameter grooves of the primary pulleys, an upward pulling force is applied on the moving pulleys and accordingly, the primary spring bed begins to rise through the moving pulley carriers, causing the compression spring to compress. As the pressure spring compresses, the force on it increases and in order to ensure the moment balance on the primary pulleys, the movement of the parts of the primary ropes coming out of the pressure spring takes place from the grooves in the large diameter part of the primary pulleys to the grooves in the small diameter part. In other words, the distance of the position where the parts of the primary ropes coming out of the compression spring start to be wound on the primary pulleys to the centers of the primary pulleys decreases at a certain rate with the downward movement of the secondary moving column and therefore the primary moving column. Thanks to this distance change, moment balance on the primary pulleys is ensured and the counterload balancing function is fulfilled. Depending on the force applied to the secondary moving column, the movement ends when it reaches its lowest position, and especially as the movement of the primary ropes ends, the movement of the movement mechanism also ends. Then, when force is applied to the secondary movable column in the lowest position to rotate the secondary movable column to the highest position, the primary movable column starts to move upwards via the secondary ropes. Therefore, the primary ropes, which are separated from the primary pulleys and connected to the primary movable column, begin to move upwards together with the primary movable column and start to be wound on the grooves in the fixed diameter part of the primary pulleys. As the primary ropes in question are wound on the grooves in the fixed diameter part of the primary pulleys, the primary pulleys begin to rotate around the primary shaft in a second rotation direction that is exactly opposite to the first rotation direction. Thus, the parts of the primary ropes that come out of the pressure spring and are wrapped in the grooves on the variable diameter part of the primary pulleys become empty on the primary pulleys, and as a result, the primary spring bed to which the movable pulleys are attached begins to move downwards through the movable pulleys and therefore the movable pulley carriers. Depending on the movement of the primary spring bearing in this direction, the pressure spring relaxes and the force on the pressure spring decreases. As the force on the pressure spring decreases, in order to balance the moment on the primary pulleys, the position where the primary ropes start to be wound on the primary pulleys is from the grooves of the small diameter part of the primary pulleys to the grooves of the large diameter part. In other words, the distance of the position where the parts of the primary ropes coming out of the compression spring start to be wound on the primary pulleys to the center of the primary pulleys increases at a certain rate with the upward movement of the secondary moving column and therefore the primary moving column. Thanks to this distance change, moment balance on the primary pulleys is ensured and the counterload balancing function is fulfilled. Depending on the force applied on the secondary moving column, the movement ends when it reaches its highest position, and especially as the movement of the primary ropes ends, the movement of the movement mechanism also ends. By using a pressure spring as a counter-load balancer in the movement mechanism of the mobile In addition, by using two different primary pulleys arranged symmetrically relative to each other in the movement mechanism and therefore two different primary ropes carrying the total load, less force is carried by each primary rope and the movable pulleys are located near the first end of the fixed column and the primary pulleys are located near the second end of the fixed column. By keeping the distance between the moving pulleys and primary pulleys as high as possible by positioning them and reducing the deviation angles of the primary ropes, the service life of the primary ropes is increased and time and cost advantages are provided in terms of maintenance and repair. In addition, by increasing the distance between the moving rollers and the primary rollers, the total vertical arm length is reduced, thus providing a more comfortable driving opportunity.

Gap Mobile X-ray device (1); a body (2), at least one wheel (3) that enables the body (2) to move on a ground (Z), fixed to the body (2) from a first end (FE4) and starting from this first end (FE4) to the ground (Z). A fixed column (4) extending along a first axis (Y) extending almost vertically to a second end (SE4), extending between a first end (FE5) and a second end (SE5) along the first axis (Y) and At least one primary movable column (5) connected to the fixed column (4) in a way that can perform linear movement relative to the fixed column (4) in the direction of the first axis (Y), a first end (FE6) and a second end (SE6) along the first axis (Y). ) and at least one secondary movable column (6) that is connected to the primary movable column (5) and the fixed column (4) in a way that can perform linear movement relative to the primary movable column (5) and the fixed column (4) along the first axis (Y), At least one At least one secondary pulley (10) arranged in a region close to the second end (SE5) of the primary moving column (5), wound on the primary pulleys (9) and fixed from one end to almost the first end (FE5) of the primary moving column (5). two primary ropes (11), at least one secondary rope (12) fixed at one end near the first end (FE4) of the fixed column (4) and fixed almost to the first end (FE6) of the secondary movable column (6) by winding over the secondary pulley (10). ) and arranged within the fixed column (4) to allow the primary ropes (11) to be entwined, through the primary ropes (11) depending on the linear movement of the primary movable column (5) and the secondary movable column (6) along the first axis (Y). At least one movement mechanism (13) that starts to operate by being triggered and is configured to balance the load resulting from the weight of at least the primary moving column (5), secondary moving column (6), X-ray tube (7) and collimator (8). ) contains. As a result of manually driving the mobile The mobile X-ray device (1) allows the carrying of the The distance in question can be adjusted thanks to the fixed column (4), the movement mechanism (13) positioned within the fixed column (4), the primary movable column (5) and the secondary movable column (6) working together. The fixed column (4), therefore the primary movable column (5) and the secondary movable column (6) connected to the fixed column (4), can preferably perform a rotation movement around the first axis (Y), thus transmitting the X-ray carried by the secondary movable column (6). Angular positioning of the tube (7) and collimator (8) can also be achieved. During the movement of the mobile This provides ease of driving for the operator driving the mobile X-ray device (1). The connections between the fixed column (4), primary movable column (5) and secondary movable column (6) are provided by primary ropes (11) and at least one secondary rope (12), preferably made of a strong material such as steel. The primary ropes (11) coming out of the primary pulleys (9) arranged near the second end (SE4) of the fixed column (4) are fixed near the first end (FE5) of the primary movable column (5), preferably the first end (FE5). Thus, the connection between the fixed column (4) and the primary movable column (5) is ensured. The secondary rope (12), which is fixed at one end near the first end (FE4) of the fixed column (4), passes through the secondary pulley (10) positioned near the second end (SE5) of the primary movable column (5) and preferably reaches the first end (FE6) of the secondary movable column (6). It is fixed near the first end (FE6). Thus, the connection between the secondary movable column (6) and the fixed column (4) is provided through the primary movable column (5). The secondary movable column (6) is preferably carried almost on the opposite side of the side of the column (6) that is connected to the primary movable column (5). Thanks to such a connection between the fixed column (4), primary movable column (5) and secondary movable column (6) by means of the primary ropes (11) and at least one secondary rope (12), the fixed column (4) In other words, the movement mechanism (13) positioned within the fixed column (4), the primary movable column (5) and the secondary movable column (6) are ensured to move simultaneously. Since there are preferably two primary pulleys (9) on the fixed column (4), two different primary ropes (11) are used to carry the primary movable column (6). The movement mechanism (13) positioned inside the fixed column (4) allows the primary moving column (5) and the secondary moving column (6) and therefore the X-ray tube (7) and the collimator (8) to move on the first axis (Y). adjusting the distance of the collimator (8) relative to the patient and after adjusting the distance of the collimator (8) relative to the patient, the primary movable column (5) and the secondary movable column (6) and therefore the X-ray tube (7) and the collimator (8) remain motionless in this position. It offers opportunities. The movement mechanism (13) in question is adapted as a counter-balanced mechanism. Thanks to the counter-balanced movement mechanism (13), a weight equivalent to the loads caused by the primary moving column (5), secondary moving column (6), X-ray tube (7) and collimator (8) is created and the said elements ( 5, 6, 7, 8) are ensured to move reliably along the first axis (Y). The primary ropes (11) separated from the primary pulleys (9) positioned near the second end (SE4) of the fixed column (4) and connected to the primary movable column (5) carry the entire load and the said primary ropes (11) are connected to the primary movable column (5). The entire load occurring in the section is kept constant during the operation of the movement mechanism (13). The fixed load in question weighs equivalent to the loads caused by the primary moving column (5), the secondary moving column (6), the X-ray tube (7) and the collimator (8). While one end of the primary ropes (11) coming out of the primary pulleys (9) positioned on the fixed column (4) is connected to the primary movable column (5), the said primary ropes (11) circulate within the movement mechanism (13) arranged within the fixed column (4) and reach the other end. They are fixed into the fixed column (4) from their ends. Thanks to the circulation of the said primary ropes (11) within the movement mechanism (13), depending on the movement of the movement mechanism (13), the secondary moving column (6) and therefore the primary moving column (5) on the first axis (Y), the movement is carried out by means of the primary ropes (11). It is triggered and enabled to move, thus creating the necessary forces to create a load equivalent to the loads caused by the primary moving column (5), secondary moving column (6), X-ray tube (7) and collimator (8). The movement mechanism (13) in the mobile X-ray device (1) of the invention; At least one first carrier table (14) connected to the fixed column (4) near the second end (SE4) of the fixed column (4), at least one second carrier table connected to the fixed column (4) near the first end (FE4) of the fixed column (4) (15), at least two primary shaft bearings (16) starting from the two almost opposite ends of the first carrier plate (14) and extending towards the direction of the first end (FE4) of the fixed column (4), between the mutual primary shaft bearings (16). At least one primary shaft (17) extending almost linearly, arranged symmetrically with respect to the center of the first carrier table (14) with a certain gap (G) between them on the primary shaft (17), some with fixed diameter and some with variable diameter. two primary pulleys (9) adapted in the form of a conical pulley with grooves on it that allow the primary ropes (11) to sit in it, two fixed pulleys (18) positioned between the primary pulleys (9) and the primary shaft bearings (16), the first carrier table. (14) and carried by the first carrier table (14), extending almost parallel to the first carrier table (14) in such a way that there is a space between the first carrier table (14) allowing the primary rollers (9) and fixed rollers (18) to be stored. At least one secondary shaft bearing (19) is located on the side of the second carrier plate (15) facing the second end (SE4) of the fixed column (4), arranged with a gap between it and the second carrier table (15) and almost parallel to the second carrier table (15). At least one primary spring bearing (20) extending as an angle, at least one secondary shaft (21) extending along the first axis (Y) by resting on the secondary shaft bearing (19) from one end and on the second carrier table (15) from the opposite end, At least one pressure spring (22) extending between the secondary shaft bearing (19) and the primary spring bearing (20) in a way to surround the secondary shaft (21) by resting on the secondary shaft bearing (19) from one end and on the primary spring bearing (20) from the other end. , at least two movable pulley carriers (23) arranged near the opposite ends of the primary spring bed (20) and the primary ropes (11) rested on said movable pulley carriers (23) and connected to the primary ropes (11) with the effect of the force carried on the primary ropes (11). It contains moving rollers (24) configured to perform almost linear movement in the direction of the axis (Y) and to allow the pressure spring (22) to compress or loosen depending on the direction of this linear movement. The pressure spring (22) located within the movement mechanism (13) tightens and loosens to meet the loads caused by the weight of the primary moving column (5), secondary moving column (6), X-ray tube (7) and collimator (8). As a result, it creates a force equivalent to these loads, allowing the movement mechanism (13) to act as a counterbalance. For this counterbalance task, a small-volume movement mechanism (13) arranged inside the fixed column (4) by using a pressure spring (22) that has compression and relaxation properties, moves the X-ray tube (7) and collimator (8) on the first axis (Y). It can provide high stroke for movement. While the X-ray tube (7) and collimator (8) move along the first axis (Y), the pressure spring (22) located within the movement mechanism (13) also moves along the first axis (Y). A certain preload is given to the pressure spring (22) before the movement mechanism (13) starts to operate, preferably before the movement mechanism (13) is mounted into the fixed column (4). The amount of pre-tensioner in question is preferably equal to the minimum force value encountered during the operation of the movement mechanism (13). For example, in order to pre-tension the tensile springs, which are frequently used in the state of the art, it is necessary to extend the length of the tensile springs in question by pulling them along their axes, and this causes the volume they occupy in the fixed column (4) to increase and the dimensions of the fixed column (4) to increase. On the other hand, in order to pre-tension the pressure spring (22) used in the movement mechanism (13) in the mobile X-ray device (1) of the invention, the pressure spring (22) in question must be compressed. In addition to the pre-tensioner, since the force acting on the mechanism (13) will increase during the operation of the movement mechanism (13), the tension springs in the mechanisms where tension springs are used extend further during use, whereas in the present invention where the compression spring (22) is used, the compression spring (22) is ensured to be thoroughly compressed. Therefore, thanks to the fact that the spring (22), which acts as counter-load balancing in the movement mechanism (13) in the mobile Compared to the examples in this case, it is ensured that it is smaller in size, especially in terms of height. Depending on the forces acting on the mechanism (13) during operation of the movement mechanism (13), the pressure spring (22) begins to narrow, in other words, compress, and the force on the pressure spring (22) increases. As the force on the pressure spring (22) increases, primary rollers (9) of the conical roller type arranged near the second end (SE4) of the fixed column (4) are used to ensure load balance. While some of the primary rollers (9) in the tapered roller type in question have a fixed diameter, the remaining part has a variable diameter. The variable diameter preferably decreases at certain rates from the larger diameter value to the lower diameter value. In addition, there are almost spiral geometry grooves on the primary pulleys (9) of the conical pulley type, which are suitable for receiving the primary ropes (11) in question, and the primary ropes (11) can move in these grooves. The primary rope (11), coming out of the fixed diameter part of the primary pulley (9), which has such a structure, is connected to the vicinity of the first end (FE5) of the primary movable column (5), preferably the first end (FE5), and this connection is Thanks to this, the moment on the primary pulley (9) of the loads caused by the weight of the primary moving column (5), secondary moving column (6), X-ray tube (7) and collimator (8) remains constant. When the force on the pressure spring (22) located in the movement mechanism (13) increases, the variable diameter of the primary rollers (9) decreases from a larger diameter to a smaller diameter in order to ensure counterbalance. Thus, the moment of the primary pulley (9) on the pressure spring (22) side remains constant and the loads caused by the weight of the primary moving column (5), secondary moving column (6), X-ray tube (7) and collimator (8) are removed from the primary pulley (8). 9) is ensured to be equal to the moment it creates on it. Thanks to the equality of the moments in question, it is ensured that the counter-balanced movement mechanism (13) performs its function reliably. The primary rollers (9) in question are mounted on the primary shaft (17) located within the movement mechanism (13). In the preferred embodiment of the invention, the primary rollers (9) are arranged on the primary shaft (17) symmetrically with respect to the middle plane of the movement mechanism (13). Fixed rollers (18) are also mounted on the said primary shaft (17), symmetrically with respect to the middle plane of the movement mechanism (13). Since the use of two primary pulleys (9) in the said movement mechanism (13) requires the use of two different primary ropes (11), it causes the load on each of the primary ropes (11) to be halved compared to the use of a single primary rope (11). The service life of the ropes (11) is increased. The primary shaft (17), on which the primary rollers (9) and fixed rollers (18) are mounted, extend parallel to each other in the direction of the first axis (Y) from each end and are arranged at a distance so that there is almost an opening between them that allows the primary shaft (17) to be placed. It is connected to the primary shaft bearings (16) in such a way that the said primary shaft (17) rotates around its extension axis. Primary shaft bearings (16) are fixed on the first carrier plate (14), preferably at one end, near the end parts of the first carrier plate (14). In the movement mechanism (13), an almost pulley-like structure emerges through the primary pulleys (9), fixed pulleys (18) and moving pulleys (24). Since two primary pulleys (9) and therefore two primary ropes (11) are used in the movement mechanism (13) in question, two different pulley systems emerge that are symmetrical with respect to the middle plane of the movement mechanism (13). With the movement of the secondary moving column (6) on the first axis (Y) and therefore the triggering of the primary moving column (5), the primary ropes (11) are wrapped in the grooves of the primary pulleys (9) depending on the direction of movement of the secondary moving column (6). It also comes out of these grooves in vain. The force carried on the primary ropes (11) wound on the primary pulleys (9) or released from these primary pulleys (9) is the pulley created by the primary pulley (9)-fixed pulley (18)-movable pulley (24) group. Thanks to the system, it is transferred to the pressure spring (22) in a ratio of 4 to 1, ensuring that the pressure spring (22) has a lower stroke. Movable pulleys (24), which allow the pressure spring (22) in the movement mechanism (13) to tighten and loosen on the first axis (Y), are mounted on the primary spring bearing (20) arranged near the first end (FE4) of the fixed column (4) connected to the body (2). It is carried on positioned movable roller carriers (23). Since the movable roller carriers (23) are arranged on the primary spring bed (20), which can move together with the pressure spring (22) that can perform almost linear movement on the first axis (Y), the said primary spring bed (20) is also located on the primary spring bed (20) together with the moving rollers (24). It performs almost linear movement in the direction of the axis (Y) and as a result, the compression spring (22) is compressed or loosened depending on the direction of the movement. As stated before, the movement of the movement mechanism (13) is provided by the primary ropes (11) winding inside it. The fixed end of each of the primary ropes (11), in other words, the end that is not connected to the primary moving column (5), is connected to the first carrier table (14) and from there, respectively, to the moving pulley located on the side where the movement mechanism (13) is connected to the first carrier table (14). (24) extends to be wrapped around the fixed pulley (18), the movable pulley (24) and the grooves on the variable diameter part of the primary pulley (9). After the primary rope (11) is wrapped in the grooves in the variable diameter part of the primary pulley (9), it continues to be wrapped in the grooves in the fixed diameter part and is then separated from the primary pulley (9) and placed near the first end (FE5) of the primary moving column (5). ) is fixed on it. Both primary ropes (11) extend similarly on both sides of the middle plane of the movement mechanism (13), following the same order. The moving pulleys (24) in the movement mechanism (13), the primary moving column (5), the secondary moving column (6), the X-ray tube (7) and the collimator (8) carry the loads caused by the weight of the primary ropes (1 1). It transmits to the pressure spring (22), and the said moving rollers (24) are located almost at the bottom of the movement mechanism (13), in other words, in an area quite close to the first end (FE4) of the fixed column (4), preferably where the primary spring bearing (20) is connected to each other. They are arranged on movable roller carriers (23) arranged at their opposite ends. Thanks to the positioning of the said movable rollers (24) near the first end part (FE4) of the fixed column (4) and the primary rollers (9) near the second end part (SE4) of the fixed column (4), the movable rollers (24) and the primary rollers (9) The distance between them is arranged as the highest possible distance within the almost fixed column (4), thus ensuring that the deviation angle of the primary ropes (11) extending between the relevant primary pulleys (9) and movable pulleys (24) is reduced as much as possible. By decreasing the deflection angles of the primary ropes (11), the primary ropes (11) fatigue less and have a longer life. In addition, by positioning the movable rollers (24) near the first end part (FE4) of the fixed column (4), the pressure spring (22) and the primary rollers (9) are ensured to be as close to each other as possible. This situation ensures that the dimensions of the movement mechanism (13) are lower, especially in terms of height, and allows the fixed column (4) to be even shorter. When a force is applied by the operator in the direction of the first axis (Y) on the primary moving column (5) or the second moving column (6), the movement mechanism (13) also starts to work. An example operation of the movement mechanism (13) is as follows: When a certain force is applied by the operator on the secondary moving column (6), which is in the farthest position from the body (2) on the first axis (Y), in the direction facing the body (2) along the first axis (Y). The secondary rope (12) starts to move, causing both the secondary moving column (6) and the primary moving column (5) to start moving simultaneously towards the direction of the body (2) on the first axis (Y). As the primary moving column (5) starts to move towards the body (2), the primary ropes (11) connected to the primary moving column (5) from one end also move towards the direction of the body (2). As a result of the movement of the primary ropes (11), the primary pulleys (9) also begin to rotate around the primary shaft (17) in a predetermined first rotation direction, such as counterclockwise. As a result of the rotational movement of the primary pulleys (9) in the first direction of rotation, the parts of the primary ropes (11) wrapped around the fixed diameter part of the primary pulleys (9) come loose and move towards the body (2) simultaneously with the movement of the primary moving column (5). Before the operator applies force on the secondary moving column (6), in other words, when the secondary moving column (6) is in the farthest position from the body (2) on the first axis (Y), the parts of the primary ropes (11) coming out of the pressure spring (22) are placed on the primary pulleys. (9) is located in the grooves located in the large diameter part. As a result of the movement of the secondary moving column (6) and therefore the primary moving column (5) towards the body (2) and the rotation of the primary pulleys (9) in the direction of the primary rotation, the parts of the primary ropes (11) coming out of the pressure spring (22) are placed under the primary pulleys (9). ) is wrapped around the grooves on its variable diameter part. As the parts of the primary ropes (l 1) coming out of the pressure spring (22) are wound on the variable diameter grooves of the primary pulleys (9), a pulling force is applied on the moving pulleys (24) in the direction of the first axis (Y) in the direction opposite to the direction of the body (2) and accordingly As a result, by means of the movable roller carriers (23), the primary spring bearing (20) begins to move in the opposite direction of the body (2), in other words, in the direction of the pulling force applied to the movable rollers (24), causing the compression spring (22) to begin to compress. As the pressure spring (22) compresses, the force on it increases and in order to ensure the moment balance on the primary pulleys (9), the movement of the parts of the primary ropes (l 1) coming out of the pressure spring (22) takes place from the grooves in the large diameter part of the primary pulleys (9) to the grooves in the small diameter part. . In other words, the distance of the position where the parts of the primary ropes (ll) coming out of the pressure spring (22) start to be wound on the primary pulleys (9) to the centers of the primary pulleys (9) is the distance of the secondary moving column (6) and therefore the primary moving column (5) to the body (2). ) decreases at a certain rate with its movement in the right direction. Thanks to this distance change, moment balance on the primary pulleys (9) is ensured and the counterload balancing function is fulfilled. Depending on the force applied on the secondary moving column (6), when it reaches the position where it is closest to the body (2) on the first axis (Y), the movement ends, and especially as the movement of the primary ropes (11) ends, the movement of the movement mechanism (13) also ends. Then, on the secondary movable column (6), which is in the closest position to the body (2) on the first axis (Y), in order to move the secondary movable column (6) away from the body (2) to the position where it is furthest from the body (2) on the first axis (Y). When force is applied, the primary moving column (5) starts to move in the direction away from the body (2) by means of the secondary ropes (12). Therefore, the primary ropes (11), which are separated from the primary pulleys (9) and connected to the primary movable column (5), start to move together with the primary movable column (5) in the direction of the movement of the primary movable column (5) and start to be wound on the grooves in the fixed diameter part of the primary pulleys (9). . As the primary ropes (11) in question are wound on the grooves in the fixed diameter part of the primary pulleys (9), the primary pulleys (9) begin to rotate around the primary shaft (17) in a second rotation direction that is exactly opposite to the first rotation direction. Thus, the parts of the primary ropes (11) coming out of the pressure spring (22) and wrapped in the grooves on the variable diameter part of the primary pulleys (9) come out empty on the primary pulleys (9), and as a result, the moving pulleys (24) and therefore the moving pulley carriers (23). ) the primary spring bearing (20), to which the moving rollers (24) are connected, begins to move towards the body (2) on the first axis (Y). Depending on the movement of the primary spring bearing (20) in this direction, the pressure spring (22) loosens and the force on the pressure spring (22) decreases. As the force on the pressure spring (22) decreases, in order to balance the moment on the primary pulleys (9), the position where the primary ropes (11) begin to wind on the primary pulleys (9) shifts from the grooves of the small diameter part of the primary pulleys (9) to the grooves of the large diameter part. In other words, the distance of the position where the parts of the primary ropes (11) coming out of the pressure spring (22) start to be wound on the primary pulleys (9) to the center of the primary pulleys (9) is the distance of the secondary moving column (6) and therefore the primary moving column (5) on the first axis. (Y) increases at a certain rate with the movement of the body (2) towards the opposite direction. Thanks to this distance change, moment balance on the primary pulleys (9) is ensured and the counterload balancing function is fulfilled. Depending on the force applied on the secondary moving column (6), the movement ends when it reaches the position where it is furthest from the body (2) on the first axis (Y), and especially as the movement of the primary ropes (11) ends, the movement of the movement mechanism (13) also ends. In one embodiment of the invention, the movement mechanism (13); At least one first carrier (25) arranged to perform linear movement on the secondary shaft (21) in the extension axis of the secondary shaft (21), and at least one first carrier bearing (26) configured to bear the first carrier (25) on the secondary shaft (21). , at least one second carrier (27) arranged in a way to perform linear movement on the secondary shaft (21) in the extension axis of the secondary shaft (21), with a certain distance between the first carrier (25), and the second carrier (27) on the secondary shaft (21). At least one second carrier bearing (28) configured to bear on the secondary carrier (27), a third carrier (29) arranged to perform linear movement on the secondary shaft (21) in the extension axis of the secondary shaft (21), with a certain distance between it and the second carrier (27). , a third carrier bearing (30) configured to bear the third carrier (29) on the secondary shaft (21) and placed on the primary spring bearing (20), the first carrier bearing (26) on the secondary shaft bearing (19) from one end and the first carrier bearing (26) from the other end. A first pressure spring (31) is placed on it and extends between the secondary shaft bearing (19) and the first carrier bearing (26) in a way to center the secondary shaft (21), and on the first carrier bearing (26) from one end and the second carrier bearing (28) from the other end. A second pressure spring (32) is placed on the second carrier bearing (28) and extends between the first carrier bearing (26) and the second carrier bearing (28) in a way to center the secondary shaft (21). It consists of a third pressure spring (33) which is supported on 30) and extends between the second carrier bearing (28) and the third carrier bearing (30) to center the secondary shaft (21). In this application, the first compression spring (31), the second compression spring (32) and the third compression spring (33) are respectively connected to the secondary shaft bearing (19), first carrier bearing (26), second carrier bearing (28) and third carrier bearing (30). It is supported around the secondary shaft (21) in a way to center the secondary shaft (21). In addition, the first carrier (25), the second carrier (27) and the third carrier (29) arranged on the secondary shaft (21) provide the bearing of the first compression spring (31), the second compression spring (32) and the third compression spring (33), respectively. It also ensures that the first compression spring (31), the second compression spring (32) and the third compression spring (33) move along the first axis (Y) by coinciding with the extension axis of the secondary shaft (21). In this embodiment of the invention, instead of a single compression spring (22), different independent pressure springs are used, namely the first compression spring (31), the second compression spring (32) and the third compression spring (33), and each individual compression spring (31, 32, 33) is used. ) is ensured to be smaller in size than a single pressure spring (22), and the bending or buckling of the pressure springs (31, 32, 33) while the movement mechanism (13) is operating is minimized or completely eliminated. This situation allows both the reliability of the movement mechanism (13) to increase during its operation and the pressure springs (31, 32, 33) to be used for a longer period of time without being damaged. In one embodiment of the invention, the movement mechanism (13); In order to prevent the pre-tension applied on the pressure spring (22), which is arranged in the space between the second carrier plate (15) and the primary spring bearing (20), to be eliminated and to prevent the said pressure spring (22) from coming to the un-pre-tensioned area, a certain pressure is placed on the secondary shaft (21). It contains at least one compression element (34) configured to apply force. In an embodiment of the invention, the compression element (34) in question has a nut shape that is suitable for mating with the relevant teeth of the secondary shaft (21), at least part of which has a toothed structure. Thanks to the compression force applied by the compression element (34) to the secondary shaft (21), the pre-tension given to the pressure spring (22) preferably during assembly is maintained, thus preventing the pressure spring (22) from reaching an extended length where the pre-tension is lost over time. In addition, the load value on the movement mechanism (13) is maintained thanks to the protection of the pre-tensioner on the pressure spring (22). In an embodiment of the invention, mobile X-ray device (1); It is placed in the space (G) between two primary rollers (9), adapted to take a first position in which at least one of the primary rollers (9) is contacted and at least a second position in which both primary rollers (9) are not contacted, and is adapted to take a first position. It contains at least one stopper (35) configured to prevent the primary rollers (9) from rotating around the primary shaft (17) when in position. The stopper (35) is preferably a magnetic brake and when it is in the first position, it holds on to at least one of the primary pulleys (9) and prevents the primary pulley (9) to which it is attached from performing a rotation movement around the primary shaft (17). By taking the first position of the stopper (35) and preventing the primary rollers (9) from performing a rotational movement around the primary shaft (17), the movement mechanism (13) and therefore the primary moving column (5) and the secondary moving column (6) are kept motionless. Thus, especially for x-ray shooting, after adjusting the distance between the collimator (8) and the patient on the first axis (Y), the collimator (8) and the In addition, thanks to the stopper (35) in question preventing the rotational movement of the primary rollers (9), while the mobile Driving comfort is increased by preventing involuntary movements in the direction of the axis (Y). In an embodiment of the invention, mobile X-ray device (1); At least one stopper bed (36) mounted on the first carrier table (14) so that the stopper (35) is positioned in the space (G) between the two primary rollers (9) and having at least one open hole on it, said open hole. At least one holder (37) positioned inside and allowing the stopper (35) to be held securely by wrapping it around the stopper (35), and the holder (37) is moved in a controlled manner between the first position and the second position to ensure that the stopper (35) takes the first position and the second position. It contains at least one guide shaft (38) that allows it to move. In one application, the stopper bearing (36) is mounted on the first carrier table (14) by means of bolts, screws and similar detachable fasteners. This type of structure, which carries the stopper (35) that prevents the movement of at least one of the primary rollers (9) and ensures that the movement mechanism (13) and therefore the primary moving column (5) and the secondary moving column (6) remain motionless, can be detachably attached to the first carrier table (14). ) mounting, for example, in case the stopper (35) fails, the stopper bed (36) can be easily removed from the first carrier table (14) and the stopper (35) can be repaired or replaced with a new one in a short time. This provides the advantage of ease of maintenance. In an embodiment of the invention, mobile X-ray device (1); It contains two different secondary pulleys (10) arranged symmetrically to each other on the primary moving column (5) and two different secondary ropes (12) that can be wound on these secondary pulleys (10). Thus, two different secondary ropes (12) are used to carry the secondary moving column (6). Therefore, by using two primary ropes (11) and two secondary ropes (12) to carry both the primary mobile column (5) and the secondary mobile column (6), the forces acting on each primary rope (11) and secondary rope (12) will decrease. It is ensured that primary ropes (11) and secondary ropes (12) can be used for longer periods. Thanks to the use of a pressure spring (22) as a counter-load balancer in the movement mechanism (13) in the mobile (1) It is possible to see the front more easily while driving, thus increasing driving comfort and safety. In addition, by using two different primary pulleys (9) arranged symmetrically with respect to each other in the movement mechanism (13) and therefore two different primary ropes (11), less force is carried by each primary rope (11) and the moving pulleys (24) are fixed. By positioning the primary pulleys (9) near the first end (FE4) of the column (4) and near the second end (SE4) of the fixed column (4), keeping the distance between the movable pulleys (24) and primary pulleys (9) as high as possible, the deflection of the primary ropes (11) is ensured. By reducing the angles, the service life of the primary ropes (11) is increased and thus time and cost advantages are provided in terms of maintenance and repair. In addition, since the pressure spring (22) is mounted directly on the secondary shaft bearing (19) from one end, the distance between the primary rollers (9) and the pressure spring (22) is kept lower than the applications in the state of the art, thus the length of the movement mechanism (13) is minimized and the primary shaft bearing (19) is mounted. In the positions where the movable column (5) and the secondary movable column (6) are furthest from the body (2), their height relative to the ground (Z) is much lower than in the known state of the art. In addition to all these, the stopper (preferably adapted as a magnetic brake) is used to prevent the rotational movement of the primary rollers (9) around the primary shaft (17) when desired, ensuring that the movement mechanism (13) and therefore the primary moving column (5) and the secondary moving column (6) remain motionless. 35) is removably mounted on the first carrier table (14), which is easily accessible through the stopper bed (36), allowing any malfunction that may occur in the stopper (35) to be eliminated in a short time and with low workmanship.TR TR
