The ground rail is the basic support and guide structure for the operation of the stacker. Its fixed stability and reliability directly affect the operational safety and efficiency of the stacker.

[0003] There are many problems with the existing stacker floor rail fixing method. On the one hand, the existing rigid pressing block clamping fixing method, during the long-term operation of the stacker, due to the repeated periodic vibration of the floor rail, the bolts fixing the rigid pressing block are prone to loosening, which leads to the floor rail being not firmly fixed, which may not only cause safety accidents, but also increase the maintenance cost and downtime of the equipment. On the other hand, the fixing structure has high requirements on the force direction of the top of the floor rail, otherwise the long-term vibration will easily cause the floor rail to tilt to one side. In long-term use, the stability is difficult to guarantee, and it is easy to loosen and affect the normal operation of the stacker.

The screw at the lower end will offset the downward force, so that the balancing component cannot tilt, and further the blocking block cannot be skewed. While achieving good anti-seismic stability of the device, the device is not prone to skew, thereby further enhancing stability.

[0019] 4. The present invention adopts a combined structural arrangement of a balancing component and an elastic component, so that compared with an ordinary spring structure, the spring can provide good elastic deformation ability and buffering performance, can be compressed or stretched when subjected to external force, absorb and store energy, and return to its original state after the external force disappears. It has better elasticity and buffering performance, structural strength and stability, and stronger adjustability and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment 1: See also Figure 1-4 ; When the existing bolt fixing mechanism vibrates, the screw rod 21 slides up in a spiral. When the fastening nut 22 is fixed to the fixing seat 14, the fastening nut 22 and the fixing seat 14 move up at the same time, causing the fixing seat 14 to loosen. When the fastening nut 22 and the fixing seat 14 are not fixed, the fastening nut 22 can slide and follow the rotation, which will cause the fixing seat 14 to follow and move up, causing the fixing seat 14 to loosen. Therefore, when we control the fastening nut 22 not to move synchronously with the screw rod 21, it can be achieved that the upward sliding of the screw rod 21 will not cause the fixing seat 14 to loosen, and the stability of the fixing seat 14 can be achieved. Therefore, we have added a washer 23 and a synchronous nut 24; by designing the structural relationship between the washer 23 and the synchronous nut 24 and the screw rod 21 and the fastening nut 22 respectively, when the screw rod 21 rotates in a spiral, the synchronous nut 24 can only follow the rotation to move up.

[0023] The stacker ground rail fixing mechanism in the present embodiment includes a ground rail 11, and the ground rail 11 includes a support seat 12, a connecting seat 13 and a fixing seat 14; the support seat 12 is used to support the stacker, and the two ends of the connecting seat 13 are respectively connected to the support seat 12 and the fixing seat 14, and the two ends of the fixing seat 14 are provided with vertical fixing mechanisms, and the top of the vertical fixing mechanism is close to each other. The side is provided with a synchronization mechanism, and the synchronization mechanism is slidably arranged on the top of the connecting seat 13 through a balancing mechanism. The vertical fixing mechanism fixes the fixing seat 14 and the ground by bolt connection, and the synchronization mechanism is used to offset the external vibration that drives the vertical fixing mechanism to slide upward; the balancing mechanism prevents the fixing seat 14 from tilting by synchronizing the positions of the vertical fixing mechanisms at both ends.

[0024] As a further solution of this embodiment, the vertical fixing mechanism includes a screw 21, a fastening nut 22, a washer 23 and a synchronous nut 24; a threaded hole is opened through the top of the fixing seat 14, and a fastening nut 22, a washer 23 and a synchronous nut 24 are sequentially arranged on the top of the fixing seat 14, the screw 21 is adapted to the threaded hole, the fastening nut 22 and the synchronous nut 24 in sequence through threaded connection, an inner clip 31 and an outer clip 33 are fixedly connected to the washer 23, and the inner clip 31 and the outer clip 33 are rotatably connected to the washer 23 respectively; a screw groove 32 is opened on the screw 21 corresponding to the inner clip 31, and a nut groove 34 is opened on the synchronous nut 24 corresponding to the outer clip 33, the inner clip 31 is movably adapted to the screw groove 32, and the outer clip 33 is movably adapted to the nut groove 34.

[0025] As a further solution of this embodiment, when the floor rail 11 is installed, the fastening nut 22 is fixed, and the screw 21 is rotated so that the end of the screw 21 is screwed into the ground; after the screw 21 is rotated to a specified depth, the inner clip 31 on the inner side of the washer 23 is rotated so that the inner clip 31 is perpendicular to the washer 23, and then the washer 23 is sleeved on the outer side of the screw 21 and abuts against the fastening nut 22, at this time, the screw groove 32 and the inner clip 31 are movably engaged; then, the synchronous nut 24 is screwed into the washer 23 until it abuts against the washer 23, and the outer clip 33 on the outer side of the washer 23 is rotated so that the outer clip 33 is perpendicular to the synchronous nut 24 and movably engages with the nut groove 34; at this time, when the external vibration drives the screw 21 to spirally slide upward, the synchronous nut 24 follows the screw 21 to spirally slide upward under the action of the washer 23.

[0026] Furthermore, a limiting nut 25 is also provided at the bottom of the fixing seat 14, and both ends of the limiting nut 25 are respectively concave to the bottom of the fixing seat 14 and the bottom of the ground, and the screw rod 21 is threadedly connected to the limiting nut 25. By setting the concave limiting nut 25, the screw rod 21 can be effectively prevented from tilting.

[0027] In this example, when the existing bolt fixing mechanism vibrates, the screw rod 21 spirally slides upward, and when the fastening nut 22 is fixed to the fixing seat 14, the fastening nut 22 and the fixing seat 14 move upward at the same time, causing the fixing seat 14 to loosen; when the fastening nut 22 and the fixing seat 14 are not fixed, the fastening nut 22 can slide and follow the rotation, which will cause the fixing seat 14 to move upward, causing the fixing seat 14 to loosen. Therefore, when we control the fastening nut 22 not to move synchronously with the screw rod 21, it can be achieved that the upward sliding of the screw rod 21 will not cause the fixing seat 14 to loosen, and the stability of the fixing seat 14 can be achieved. Therefore, we have added a washer 23 and a synchronous nut 24; by designing the structural relationship between the washer 23 and the synchronous nut 24 and the screw 21 and the fastening nut 22 respectively, when the screw 21 rotates spirally, the synchronous nut 24 can only move up with the rotation, thereby causing the fastening nut 22 to move up. When the synchronous nut 24 cannot move up, the screw 21 cannot slide up, so that the sliding of the screw 21 will not cause the fixing seat 14 to loosen.

[0028] Embodiment 2: See also Figure 1-8 ; In the first embodiment, there is no synchronization mechanism design for blocking the synchronization nut 24 from moving upward when the screw rod 21 rotates helically.

[0029] The synchronizing mechanism comprises a blocking block 41, a first extension spring 42, a vertical slider 43, a second extension spring 44 and a synchronizing block 45; the top end of the screw rod 21 is abutted against the blocking block 41, and one end of the blocking block 41 close to the support seat 12 extends into the interior of the support seat 12, and the bottom end of the blocking block 41 in the support seat 12 is movably abutted against the vertical slider 43, and the bottom end of the vertical slider 43 is fixedly connected to the second extension spring 44, and the vertical slider 43 is slidably connected to the connecting seat 13 through a limiting unit, and the second extension spring 44 enables the vertical slider 43 to maintain an upward sliding trend, and the end of the blocking block 41 close to the support seat 12 is also connected to the first extension spring 42, and the first extension spring 42 enables the blocking block 41 to keep away from the support seat 12, and the end of the second extension spring 44 away from the support seat 12 is fixedly connected to the synchronizing block 45, and the end of the synchronizing block 45 abuts against the top of the synchronizing nut 24.

[0030] In this embodiment, (when the screw rod 21 spirals upward, the blocking block 41 is driven to slide toward the side close to the support seat 12, so that the vertical sliding block 43 slides down, driving the second extension spring 44 to slide down, and then the second extension spring 44 drives the synchronous nut 24 to move downward, but because the screw rod 21 spirals upward, it will drive the synchronous nut 24 to follow the spiral upward, so the upward and downward forces borne by the synchronous nut 24 offset each other, so that the screw rod 21 is reset, so that the vertical fixing mechanism has strong anti-seismic ability and high stability).

[0031] Embodiment 3, In the first and second embodiments, the sliding of the screw rod 21 may cause the blocking block 41 to tilt, so that the vertical slider 43 cannot move. In order to prevent the blocking block 41 from tilting, a balancing mechanism is provided.

[0032] Wherein, the balancing mechanism includes an upper clamping block 51, an upper slide groove 52, a fixed block 53, a lower clamping block 54, a linkage groove 55, a sliding groove 56 and a limiting cavity 57; a connecting groove is provided in the middle of the connecting seat 13, which runs through the left and right ends of the connecting seat 13; the upper clamping block 51 is arranged at the top of the connecting groove, the upper slide groove 52 is symmetrically provided on the inner top wall, the fixing block 53 is fixedly connected to the middle of the upper clamping block 51, the lower clamping block 54 is fixedly connected to the bottom of the fixing block 53, and the sliding groove 56 is provided on the inner bottom wall of the lower clamping block 54; the upper clamping block 51 and the lower clamping block 54 are connected by an elastic component, and the upper clamping block 51 and the lower clamping block 54 are both provided with U-shaped parts, and the elastic component makes the openings of the upper clamping block 51 and the lower clamping block 54 keep close to each other. When the openings of the upper clamping block 51 and the lower clamping block 54 abut, the middle parts of the upper clamping block 51 and the lower clamping block 54 jointly form the limiting cavity 57.

[0033] The blocking blocks 41 on both sides are slidably arranged inside the limiting cavity 57 and are respectively slidably arranged at the two ends of the fixed block 53. The blocking blocks 41 on both sides are fixedly connected to the blocking blocks 41 by the first extension spring 42. The top and bottom of the blocking block 41 are respectively provided with an upper slider 61 and a lower slider 62 corresponding to the upper slide groove 52 and the lower slide groove 56. The upper slider 61 is slidably arranged inside the upper slide groove 52, and the lower slider 62 is slidably arranged inside the lower slide groove 56. The lower clamping block 54 is provided with the linkage groove 55 corresponding to the vertical slider 43. The vertical slider 43 is movably abutted against the blocking block 41 through the linkage groove 55. The side of the vertical slider 43 close to the connecting seat 13 is also fixedly connected with the sliding block 63. The connecting seat 13 is correspondingly provided with the vertical slide groove 64. The vertical slider 43 is slidably arranged inside the connecting seat 13 through the cooperation of the sliding block 63 and the vertical slide groove 64.

At this time, the upper clamping block 51 and the upper slide groove 52 are jointly provided with the connecting cavity 71, and the compression spring 72 is installed in the connecting cavity 71. The two ends of the compression spring 72 are respectively connected to the upper clamping block 51 and the upper slide groove 52. The compression spring 72 keeps the upper clamping block 51 and the upper slide groove 52 close to each other. When the upper clamping block 51 and the upper slide groove 52 are in contact, the combination of the upper clamping block 51 and the upper slide groove 52 can extend into the interior of the connecting groove. At least one group of the elastic components is provided at both ends of the synchronization component.

[0035] As a further solution of this embodiment, both ends of the blocking block 41 are provided with rounded corners, and the end of the vertical sliding block 43 abutting against the blocking block 41 is also provided with a chamfer. Embodiment 4: A stacker comprises the stacker ground rail fixing mechanism.

[0036] In summary, the present invention adopts the structural design between the washer and the synchronous nut and the screw in the vertical fixing mechanism, so that when the screw rotates, the synchronous nut can only move upward with the rotation, which limits the movement direction of the nut in the existing fixing mechanism and provides the possibility of further preventing the movement of the nut. Then, through the structural design of the blocking block, the first extension spring, the vertical slider, the second extension spring and the synchronous block, when the screw rotates upward, the blocking block is driven to slide toward the side close to the support seat, so that the vertical slider slides down, driving the second extension spring to slide down, and then the second extension spring drives the synchronous nut to move downward, but because the screw rotates upward, it will drive the synchronous nut to follow the spiral upward, so the upward and downward forces of the synchronous nut offset each other, so that the screw is reset, so that the vertical fixing mechanism has strong anti-seismic ability and high stability. Furthermore, through the combined structural setting of the balancing component and the synchronization component, the blocking block is slidably set inside the balancing component. Since the balancing component is symmetrically connected to the seat, when one end of the balancing component tilts upward, it will drive the other end to tilt downward. The screw at the lower end will offset its downward force, making it impossible for the balancing component to tilt, and then making the blocking block unable to tilt. While achieving good anti-seismic stability of the device, the device is not prone to tilting, further enhancing stability. Finally, through the combined structural setting of the balancing component and the elastic component, the present invention can provide good elastic deformation ability and buffering performance compared to ordinary circular structures. It can be compressed or stretched when subjected to external force, absorb and store energy, and return to its original state after the external force disappears. It has better elasticity and buffering performance, structural strength and stability, and stronger adjustability and adaptability.
