Description

Technical Field

[0001] The present application relates to the technical field of lifting equipment, and in particular to an ultra-high-speed low-vacuum pipe beam handling device. Background Art

[0002] The ultra-high-speed low-vacuum pipe beam is an important component of the ultra-high-speed low-vacuum pipeline. The ultra-high-speed low-vacuum pipe beam is made of concrete. After the pouring is completed, a gantry crane is usually used as a handling equipment to transport the ultra-high-speed low-vacuum pipe beam to other areas for storage so that the pouring station can continue to pour the next ultra-high-speed low-vacuum pipe beam.

[0003] Since the ultra-high-speed low-vacuum pipe beam is heavy, after the gantry crane lifts the ultra-high-speed low-vacuum pipe beam, the overall weight of the gantry crane can be increased, thereby increasing the kinetic energy of the gantry crane when moving. Although the gantry crane is provided with a brake on the traveling wheel, the brake can stop the traveling wheel. However, in windy weather, it is difficult to stop the gantry crane with large kinetic energy by relying solely on the brake. Therefore, it is necessary to add a windproof braking device to the gantry crane. For example, Chinese patent publication number CN218665054U discloses an automatic windproof rail clamping device for a gantry crane, which can drive the clamping block to clamp on the track through an electric hydraulic push rod to enhance the braking ability of the gantry crane.

[0004] In the above scheme, although the braking ability of the gantry crane is enhanced, the clamping block will directly clamp on the track. When the wind is strong, the sudden braking formed by the track-clamping braking force can easily cause the gantry crane with high kinetic energy to collapse. Summary of the Invention

[0005] In order to enhance the braking capability of the gantry crane without increasing the risk of collapse of the gantry crane, the present application provides an ultra-high-speed low-vacuum pipe beam handling equipment.

[0007] Optionally, the resistance part includes a resistance block and a resistance spring. The resistance block is slidably arranged in the resistance groove. The resistance spring is connected between the resistance block and the bottom of the resistance groove. The resistance spring is used to apply a blocking force to the resistance plate when the resistance plate pushes the resistance block. From the end of the force-boosting slide groove away from the track to the end of the force-boosting slide groove close to the track, the elastic coefficients of multiple resistance springs increase one by one.

The brake provided on the traveling wheel can drive the brake plate to slide when the traveling wheel is braked, so that the wear-resistant lining on the brake block can abut against the rail. Under the action of the friction between the rail and the wear-resistant lining, the brake slider can slide along a force-increasing chute. On the one hand, the brake slider can drive the brake block to increase the friction between the wear-resistant lining and the rail. On the other hand, the brake slider can collide with multiple resistance plates. The resistance spring can apply a blocking force to the brake slider through the resistance block and the resistance plates. The blocking force applied by the multiple resistance plates to the brake slider increases successively. Under the action of the multiple blocking forces, the brake slider can apply multiple braking forces to the gantry crane body, and the first braking force is the smallest braking force. This makes the gantry crane body less susceptible to rapid braking forces at the initial braking stage. As the braking force increases successively, the gantry crane body can be quickly stopped, thereby enhancing the braking capacity of the gantry crane body and reducing the risk of collapse of the gantry crane body.

[0019] The following is combined with Figure 1-6 This application is described in further detail.

[0020] The embodiment of the present application discloses an ultra-high-speed low-vacuum pipe beam handling device. Figure 1 An ultra-high-speed low-vacuum pipe beam handling device includes a gantry crane body 1, a traveling wheel 2, a brake plate 3, a brake mechanism 4 and a connecting rod mechanism 7.

[0021] The gantry crane body 1 is used for lifting and placing ultra-high-speed low-vacuum pipe beams.

[0022] Reference Figure 1 and Figure 2 The running wheels 2 are connected to the gantry crane body 1 and are used to move on the track. In this embodiment, two sets of running wheels 2 are provided, and there are two tracks. The two sets of running wheels 2 are rollingly arranged on the two tracks in a one-to-one correspondence. Each set of running wheels 2 is provided with two running wheels. The running wheels 2 are rotatably connected to the gantry crane body 1. The running wheels 2 are provided with brakes 21 for stopping the running wheels 2.

[0023] Reference Figure 2 and Figure 3The brake plate 3 is slidably mounted on the gantry crane body 1. Two symmetrical force-boosting chutes 31 are provided on the bottom surface of the brake plate 3. The two force-boosting chutes 31 are arranged along the length of the track and are inclined relative to the track. In this embodiment, two groups of brake plates 3 are provided, and the two groups of brake plates 3 correspond one-to-one to the two groups of running wheels 2. Each group of brake plates 3 is provided with two brake plates 3, and both brake plates 3 are located between the two running wheels 2. The two brake plates 3 are symmetrically arranged relative to the track, and the force-boosting chutes 31 on the two brake plates 3 are also symmetrically arranged relative to the track. The sliding direction of the two brake plates 3 is the direction of approaching or moving away from each other.

[0024] Reference Figure 4 The number of the braking mechanisms 4 is consistent with the number of the boosting chute 31 and corresponds one-to-one with the boosting chute 31 . The braking mechanism 4 includes a friction component 5 and a resistance component 6 .

[0025] Reference Figure 4 and Figure 5 The friction assembly 5 includes a brake slider 51 and a brake block 52. The brake slider 51 is slidably set in the force-boosting chute 31, and the starting position of the brake slider 51 is located at the end of the force-boosting chute 31 away from the track. The brake slider 51 is connected to the brake block 52, and the brake block 52 is used to elastically squeeze on the track. When the brake slider 51 slides close to the track, the brake slider 51 can gradually increase the positive pressure applied to the track by the brake block 52.

[0026] Reference Figure 4 There are multiple groups of resistance components 6 along the extension direction of the booster chute 31. The resistance components 6 are arranged in the brake groove 32 opened on the bottom of the booster chute 31. The resistance components 6 include a resistance plate 61 and a resistance part 62.

[0027] Reference Figure 6 The middle part of the resistance plate 61 is rotatably connected to the groove wall of the brake groove 32, and one end of the resistance plate 61 extends into the force-boosting groove 31. The resistance plate 61 can be completely located in the brake groove 32 by rotation, and the resistance plate 61 can remain vertically set under normal circumstances.

[0028] Reference Figure 5 and Figure 6 The resistance part 62 is located on the side of the resistance plate 61 close to the end of the boosting chute 31 away from the track. The resistance part 62 is arranged in the resistance groove 33 opened on the groove wall of the brake groove 32. The resistance part 62 is used to apply a blocking force to the resistance plate 61. The blocking force applied by the resistance part 62 can be transmitted to the brake slider 51 through the resistance plate 61 to form a braking force on the gantry crane body 1. From the end of the boosting chute 31 away from the track to the end of the boosting chute 31 close to the track, the blocking forces that can be applied by multiple resistance parts 62 are gradually enhanced.

[0029] Reference Figure 2 and Figure 5 The connecting rod mechanism 7 is respectively connected to the brake 21 and the brake plate 3. The connecting rod mechanism 7 is used to drive the brake plate 3 to slide toward the track when the brake 21 stops the running wheel 2, so that the brake block 52 abuts the track. In this embodiment, four connecting rod mechanisms 7 are provided, and they correspond one to one with the four brakes 21. Each connecting rod mechanism 7 is respectively connected to a corresponding brake 21 and two brake plates 3 adjacent to the corresponding brake 21. The two brakes 21 in the same group can jointly drive the corresponding two brake plates 3 to slide.

[0030] When in use, when it is necessary to brake the traveling wheel 2, the brake 21 is activated to stop the traveling wheel 2. The brake 21 can drive the two brake plates 3 to slide in the direction close to the track through the connecting rod mechanism 7, so that the brake block 52 can elastically abut against the track. When the brake block 52 abuts against the track, the track applies friction to the brake block 52, making it difficult for the brake block 52 to move relative to the track. At this time, the gantry crane body 1 with high kinetic energy is difficult to stop on the track under wind force. The gantry crane body 1 can carry the stopped traveling wheel 2 and the brake plate 3 to slide on the track. Since the brake block 52 is difficult to move relative to the track, the brake slider 51 can slide toward the track in the force-increasing slide groove 31. During the sliding process of the brake slider 51, the positive pressure of the brake block 52 on the track continues to increase, so that the friction between the brake block 52 and the track also continues to increase, making it increasingly difficult for the brake block 52 to slide relative to the track.

[0031] The brake slider 51 will collide with the resistance plate 61 one by one when sliding. In the process of the brake slider 51 colliding with the resistance plate 61, the resistance part 62 can transmit the blocking force to the brake slider 51 through the resistance plate 61. The blocking force applied to the brake slider 51 can form a braking force on the gantry crane body 1. Since the blocking force is a short-term collision force, the blocking force can apply a point braking force to the gantry crane body 1.

[0032] Since the blocking force of the resistance part 62 increases one by one, the blocking force that the brake slider 51 initially encounters when colliding with the resistance plate 61 is the smallest blocking force, so that the braking force applied by the brake slider 51 to the gantry crane body 1 can be gradually increased, making the gantry crane body 1 less susceptible to a large braking force when the initial kinetic energy is large, thereby making it less likely for the gantry crane body 1 to collapse due to the rapid braking force in the initial stage of braking.

[0033] As the blocking force received by the brake slider 51 increases successively, the kinetic energy of the gantry crane body 1 gradually decreases. The relatively large blocking force received by the subsequent brake slider 51 can quickly brake the gantry crane body 1 to reduce the braking distance of the gantry crane body 1.

[0034] As the blocking force received by the brake slider 51 gradually increases, the friction between the brake block 52 and the track also gradually increases. Therefore, when the brake slider 51 receives a larger blocking force, the friction between the brake block 52 and the track can keep the brake slider 51 stationary relative to the track, so that the brake slider 51 can stably apply a braking force to the gantry crane body 1.

[0035] Based on the above analysis, when the brake 21 stops the walking wheel 2, the brake slider 51 can slide obliquely toward the track in the force-boosting slide groove 31. Under the blocking force applied by the resistance plate 61 and the resistance part 62, the brake slider 51 can apply a braking force to the gantry crane body 1 multiple times, and the braking force can be increased gradually, so that the braking force applied to the gantry crane body 1 can be gradually increased in the form of a braking force, thereby enhancing the braking ability of the gantry crane body 1 on the one hand, and not easily increasing the risk of collapse of the gantry crane body 1 on the other hand.

[0036] Specifically, refer to Figure 6 The resistance part 62 includes a resistance block 621 and a resistance spring 622 .

[0037] Reference Figure 5 and Figure 6 The resistance block 621 is slidably set in the resistance groove 33, and the resistance spring 622 is fixed between the resistance block 621 and the bottom of the resistance groove 33. The resistance spring 622 is used to apply a blocking force to the resistance plate 61 when the resistance plate 61 pushes the resistance block 621. From the end of the force-boosting slide groove 31 away from the track to the end of the force-boosting slide groove 31 close to the track, the elastic coefficients of multiple resistance springs 622 increase one by one, so that the farther the brake slider 51 is from the starting position, the greater the collision reaction force it receives when it collides with the resistance plate 61.

[0038] When the resistance plate 61 rotates under the push of the brake slider 51, the end of the resistance plate 61 can drive the resistance block 621 to slide into the resistance groove 33, and the resistance spring 622 accumulates elastic force. The elastic force accumulated by the resistance spring 622 can form a blocking force on the brake slider 51 through the resistance block 621 and the resistance plate 61; since the elastic force of the resistance spring 622 can gradually increase with the sliding stroke of the brake slider 51, the brake slider 51 and the resistance plate 61 are not easily damaged when they start to collide; by setting the elastic coefficients of the resistance springs 622 to increase one by one, the blocking force transmitted by the resistance plate 61 can be increased successively.

[0039] Reference Figure 6 In order to keep the resistance plate 61 in a vertical state under normal conditions, counterweight baffles 611 are fixedly connected on both sides of one end of the resistance plate 61 that extends into the boosting chute 31.

[0040] Under the action of gravity of the counterweight baffle 611, the resistance plate 61 can maintain a vertical state in the absence of external force, so as to ensure that the resistance plate 61 can stably block the brake slider 51; the counterweight baffle 611 enhances the mechanical strength of the collision part of the resistance plate 61, so that the resistance plate 61 is not easily damaged by collision.

[0041] Reference Figure 5 In order to enable the brake block 52 to be elastically squeezed on the track, the brake slider 51 is connected to the brake box 53, and an elastic block 54 is provided in the brake box 53. The brake block 52 is slidably passed through the brake box 53. The two sides of the elastic block 54 are respectively fixedly connected to the brake box 53 and the brake block 52. The elastic block 54 is used to drive the brake block 52 to be elastically squeezed on the track.

[0042] When the brake slider 51 slides obliquely toward the track, the brake slider 51 can drive the brake box 53 to move, so that the brake box 53 moves toward the track. Since the brake block 52 has already abutted against the track, the brake box 53 can compress the elastic block 54 to increase the elastic force applied by the elastic block 54 on the brake block 52, thereby increasing the positive pressure between the brake block 52 and the track.

[0043] Reference Figure 5 In order to extend the service life of the brake block 52, a wear-resistant lining 521 is detachably connected to the side of the brake block 52 away from the elastic block 54. In this embodiment, the wear-resistant lining 521 and the brake block 52 are detachably connected by countersunk bolts. By providing a wear-resistant lining 521 that can be easily replaced, the brake block 52 is not easily worn, thereby extending the service life of the brake block 52.

[0044] Reference Figure 5 In order to improve the ability of the brake block 52 to withstand the track reaction force, a connecting rod 55 is fixedly connected between the brake slider 51 and the brake box 53. A stabilizing support rod 56 is fixedly connected to the connecting rod 55. The stabilizing support rod 56 is tilted relative to the connecting rod 55. The stabilizing support rod 56 is fixedly connected to a stabilizing slider 57. The stabilizing slider 57 is slidably set in the stabilizing slide groove 34 opened on the brake plate 3, and the stabilizing slider 57 can slide synchronously with the brake slider 51.

[0045] When the brake block 52 continuously increases the positive pressure on the track, the stabilizing support rod 56 can apply a supporting force to the brake block 52 with the stabilizing slider 57 as the support point, thereby improving the ability of the brake block 52 to withstand the reaction force of the track; when the stabilizing slider 57 and the brake slider 51 slide synchronously, the brake block 52 is not easy to rotate, so that the brake block 52 can be stably abutted against the track.

[0046] Reference Figure 4 and Figure 5When the brake slider 51 slides to the end of the boosting slide 31 closest to the track and the gantry crane body 1 has not yet stopped, the brake block 52 will slide relative to the track along with the brake plate 3. Since the positive pressure applied by the brake block 52 to the track is at its maximum at this time, the whole formed by the brake block 52 and the brake slider 51 is easily damaged.

[0047] Reference Figure 3 and Figure 5 In order to ensure that the brake block 52 is not only less susceptible to damage in the above-mentioned state but also capable of applying braking force, two relief chutes 35 are provided on the brake plate 3. The relief chutes 35 correspond one-to-one with the boosting chutes 31 and are located at the end of the boosting chutes 31 closest to the track. The relief chutes 35 are connected to the boosting chutes 31, allowing the brake slider 51 to slide from the boosting chutes 31 into the relief chutes 35, and vice versa. The relief chutes 35 are arranged at an angle relative to the track. The end of the relief chute 35 closest to the boosting chute 31 is the portion of the relief chute 35 closest to the track. The vertical distance between the end of the relief chute 35 away from the boosting chute 31 and the track is less than the vertical distance between the end of the boosting chute 31 away from the relief chute 35 and the track.

[0048] When the brake slider 51 slides from the boosting chute 31 into the de-stressing chute 35, the brake slider 51 will tilt and slide away from the track, so that the positive pressure of the brake block 52 on the track can be reduced, thereby reducing the friction between the brake block 52 and the track. When the brake slider 51 slides to the end of the boosting chute 31 closest to the track and the gantry crane body 1 is still not braked, the brake block 52 can slide relative to the track after reducing the friction. On the one hand, the brake block 52 can continue to apply braking force to the gantry crane body 1 with sliding friction. On the other hand, after the friction between the brake block 52 and the track is reduced, the brake block 52 is not easily damaged.

[0049] Specifically, refer to Figure 2 The connecting rod mechanism 7 includes a first connecting rod 71, a connecting seat 72 and a second connecting rod 73. There are two first connecting rods 71, and they correspond one to one with the brake plates 3. One end of the first connecting rod 71 is hinged to the brake plate 3, and the other ends of the two first connecting rods 71 ​​are hinged to the connecting seat 72. The connecting seat 72 is slidably set on the gantry crane body 1. The connecting seat 72 is hinged to one end of the second connecting rod 73, and the other end of the second connecting rod 73 is hinged to the brake connecting rod of the brake 21. When the brake connecting rod of the brake 21 stops the walking wheel 2, the brake connecting rod of the brake 21 can drive the two brake plates 3 to slide in the direction close to the track through the second connecting rod 73 and the first connecting rod 71.

[0050] When the brake link of the brake 21 pulls the second link 73, the second link 73 can drive the angle between the two first links 71 to decrease, so that both brake plates 3 can slide toward the track; when the brake link of the brake 21 pushes the second link 73, the second link 73 can drive the angle between the two first links 71 to increase, so that both brake plates 3 can slide off the track.

[0051] Reference Figure 4 and Figure 6 In order to enable the brake slider 51 to automatically reset to the starting position, the brake mechanism 4 also includes a reset component 8, which includes a reset rack 81, a reset gear 82 and a reset coil spring 83.

[0052] The reset rack 81 is disposed within the boost chute 31 and the de-stress chute 35 and extends along the direction in which the boost chute 31 and the de-stress chute 35 extend. The reset rack 81 is located on the walls of the boost chute 31 and the de-stress chute 35 and is fixedly connected to the brake plate 3. A reset gear 82 is rotatably connected to the brake slider 51 and meshes with the reset rack 81. When the brake slider 51 slides, the reset gear 82 is driven by the reset rack 81 to rotate. A reset coil spring 83 is fixedly disposed between the reset gear 82 and the brake slider 51 and is used to drive the reset gear 82 to rotate, allowing the brake slider 51 to automatically return to its starting position.

[0053] Among them, reference Figure 6 An annular clearance groove 511 is provided on the side wall of the brake slider 51, the reset gear 82 and the reset coil spring 83 are both located in the clearance groove 511, and the meshing portion of the reset rack 81 and the reset gear 82 is also located in the clearance groove 511.

[0054] When the brake slider 51 slides away from the starting position, the reset gear 82 on the brake slider 51 can rotate under the drive of the reset rack 81. The rotating reset gear 82 can cause the reset coil spring 83 to accumulate elastic force. After the gantry crane body 1 stops, the brake 21 releases the braking force and allows the two brake plates 3 to slide off the track. At this time, under the action of the elastic force accumulated in the reset coil spring 83, the reset gear 82 can reverse. The reversed reset gear 82 can drive the brake slider 51 to move back in the opposite direction under the meshing transmission of the reset rack 81, so that the brake slider 51 can automatically move back and reset.

[0055] Reference Figure 3 and Figure 5 In order to make the return reset of the brake slider 51 less susceptible to resistance, when the two brake plates 3 slide to the farthest position, when the brake slider 51 slides to the position where the force-boosting slide groove 31 is closest to the track, a distance is left between the brake block 52 and the track.

[0056] When the brake 21 releases the braking force on the traveling wheel 2, the brake 21 can drive the two brake plates 3 to slide to the farthest position. At this time, a distance will be left between the brake block 52 and the track, so that there will be no friction between the brake block 52 and the track, thereby making the reset of the brake slider 51 less susceptible to friction resistance.

[0057] The implementation principle of an ultra-high-speed low-vacuum pipe beam handling equipment in an embodiment of the present application is as follows: when in use, when the brake 21 stops the traveling wheel 2, the brake 21 can drive the brake block 52 to elastically abut against the track through the connecting rod mechanism 7. Under the action of kinetic energy and wind force, the gantry crane body 1 continues to move with the traveling wheel 2 and the brake plate 3, and the brake slider 51 slides in the force-enhancing slide groove 31. The brake slider 51 drives the brake block 52 to continuously increase the friction between it and the track, and the brake slider 51 collides with multiple resistance plates 61 one by one. The resistance plate 61 provides a blocking force to the brake slider 51 under the elastic force of the resistance spring 622, so that the brake slider 51 can provide the gantry crane body 1 with a gradually increasing braking force, thereby enhancing the braking ability of the gantry crane without increasing the risk of collapse of the gantry crane.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
