Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a low-noise electric double-girder crane. Background Technique

[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. The working characteristic of the crane is intermittent movement, that is, in a working cycle, the corresponding mechanisms for actions such as material taking, transporting, and unloading work alternately. The development and use of cranes in the market are becoming more and more extensive.

[0003] The traditional single-girder crane has a crossbeam guide rail, and an electric hoist is installed on the crossbeam guide rail. When the crane is working, the electric hoist on the crossbeam guide rail can only move in the extending direction of the crossbeam guide rail, resulting in the goods can only be transferred along the extending direction of the crossbeam guide rail, so that the goods transfer range is limited and cannot meet the actual use needs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a low-noise electric double-girder crane with a large transfer range, which effectively solves the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions.

[0006] A low-noise electric double-girder crane includes four vertically arranged columns. The tops of two columns on the same side are jointly fixed with a first suspension. A second suspension is slidably arranged between the two first suspensions. A secondary beam rail is arranged above the first suspension through a mounting frame. A driving mechanism is arranged on the secondary beam rail, and the driving mechanism is used to drive the second suspension to translate along the length direction of the first suspension. A main beam rail is fixed below the second suspension, and the extending direction of the main beam rail is perpendicular to the extending direction of the secondary beam rail. A transverse movement assembly that can translate along its length direction is arranged on the main beam rail, and a suspension handling mechanism for lifting goods is arranged below the transverse movement assembly.

[0007] Thus, by arranging two beam rails, namely the secondary beam rail and the main beam rail, and the extending directions of the secondary beam rail and the main beam rail are perpendicular to each other. Through the work of the transverse movement assembly, the goods can be driven to transfer along the length direction of the main beam rail, and through the work of the driving mechanism, the goods can be driven to transfer along the length direction of the secondary beam rail. Compared with the traditional single-girder crane, the transfer range is no longer limited to a single direction, greatly improving the goods transfer range and meeting the actual use needs. The two bases and the first suspension jointly form an arch frame, and the two arch frames provide a stable support for the operation of the crane, ensuring the stability of the crane during work. At the same time, the two arch frames are symmetrically arranged, and the support effect is better.

[0008] Further, on one side of each of the two first suspensions close to each other, a sliding groove is provided. Guide rods are fixed in both of the two sliding grooves. Sliding seats with sliding holes are slidably sleeved on both of the two guide rods. One end of the second suspension is fixed to the sliding seat on one side, and the other end is fixed to the sliding seat on the other side.

[0009] Further, the mounting frame includes vertical rods respectively fixed on both sides of the upper surface of the first suspension and extending vertically, and two cantilevers respectively fixed at the tops of a pair of vertical rods. The cantilevers are perpendicular to the extending direction of the first suspension, and the secondary beam rail is fixed on the two cantilevers.

[0010] Further, the driving mechanism includes a threaded rod, a driving motor, a nut seat and a connecting arm. A guide groove is provided below the secondary beam rail. The threaded rod is rotatably installed in the guide groove. The driving motor is fixed on one side of the secondary beam rail, and the output shaft of the driving motor is fixedly connected to one end of the threaded rod. The nut seat is limited and slidably installed in the guide groove and is threadedly sleeved on the threaded rod. The top end of the connecting arm is fixed to the lower surface of the nut seat, and the top end is fixedly connected to the top of the second suspension.

[0011] Further, second noise reduction plates are respectively fixed on both sides of the secondary beam rail. Both of the two second noise reduction plates extend along the length direction of the secondary beam rail, and the bottom ends of both of the two second noise reduction plates extend below the secondary beam rail.

[0012] Further, first noise reduction plates are respectively fixed on both sides of the second suspension. Both of the two first noise reduction plates extend along the length direction of the second suspension, and the bottom ends of both of the two first noise reduction plates extend below the second suspension.

[0013] Further, ball grooves are evenly distributed on the inner wall of the sliding hole of the sliding seat. The ball grooves communicate with the sliding hole. Rolling balls are rollingly and matingly installed in each of the ball grooves. The rolling balls are all exposed into the sliding hole and abut against the outer wall of the guide rod.

[0014] Further, this low-noise electric double-girder crane further includes four pedestals. All of the four pedestals are castings. The bottoms are inserted into the ground, and the tops are above the ground. Fixed seats are pre-buried at the tops of the four pedestals. Fastening seats are fixed at the bottoms of the four columns. The four fastening seats are fixedly connected to the four fixed seats one by one through fastening bolts.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows.

[0016] 1. By arranging two beam rails, namely the secondary beam rail and the main beam rail, at the same time, and the extending directions of the secondary beam rail and the main beam rail are perpendicular to each other. Through the operation of the transverse movement assembly, the goods can be driven to move along the length direction of the main beam rail. Through the operation of the driving mechanism, the goods can be driven to move along the length direction of the secondary beam rail. Compared with the traditional single-girder crane, the transfer range is no longer limited to a single direction, greatly improving the goods transfer range and meeting the actual use requirements.

[0017] 2. The utility model utilizes two bases and the first suspension to jointly form an arch frame. The two arch frames provide stable support for the operation of the crane, ensuring the stability of the crane during work. At the same time, the two arch frames are symmetrically arranged, and the support effect is better.

[0018] 3. The utility model evenly distributes rolling balls on the inner wall of the sliding hole. By using the rolling balls to contact the guide rod, the contact surface is reduced. In addition, when the sliding seat slides along the guide rod, the rolling balls roll, greatly reducing the friction between the inner wall of the sliding hole and the guide rod. This not only reduces the noise generated when the sliding seat slides, but also ensures that the sliding of the sliding seat is smooth and stable enough, achieving two goals with one action.

[0029] Please refer to Figures 1-6 , a low-noise electric double-girder crane provided by the present utility model includes four vertically arranged columns 1. The tops of two columns 1 on the same side are jointly fixed with a first suspension 2. A second suspension 3 is slidably arranged between the two first suspensions 2. A secondary beam rail 5 is provided above the first suspension 2 through a mounting frame 4. A driving mechanism 6 is arranged on the secondary beam rail 5. The driving mechanism 6 is used to drive the second suspension 3 to translate along the length direction of the first suspension 2. A main beam rail 7 is fixed below the second suspension 3. The extending direction of the main beam rail 7 is perpendicular to the extending direction of the secondary beam rail 5. A transverse movement assembly 8 that can translate along its length direction is arranged on the main beam rail 7. A suspension handling mechanism 9 for lifting goods is arranged below the transverse movement assembly 8. It is worth noting that the specific structures and working principles of the transverse movement assembly 8 and the suspension handling mechanism 9 in this application are the same as those in the Chinese patent with the application number 202321270112.X, and thus will not be elaborated in this application.

[0030] When the low-noise electric double-girder crane provided by the utility model is working, the goods are lifted to a high place by using the suspension handling mechanism 9. By the operation of the transverse movement assembly 8, the goods can be driven to move along the length direction of the main girder rail 7. By the operation of the driving mechanism 6, the second suspension 3, the main girder rail 7, the transverse movement assembly 8, the suspension handling mechanism 9 and the goods as a whole can be driven to move along the length direction of the auxiliary girder rail 5. The extending directions of the auxiliary girder rail 5 and the main girder rail 7 are perpendicular to each other. Compared with the traditional single-girder crane, the transfer range is no longer limited to a single direction, greatly improving the goods transfer range and meeting the actual use requirements.

[0031] Two bases 11 and the first suspension 2 are used together to form an arch frame. The two arch frames provide a stable support for the operation of the crane, ensuring the stability of the crane during operation. At the same time, the two arch frames are symmetrically arranged, and the support effect is better.

[0032] Specifically, sliding grooves 21 are provided on one side of the two first suspensions 2 close to each other. Guide rods 22 are fixed in the two sliding grooves 21. Sliding seats 23 with sliding holes 231 are slidably sleeved on the two guide rods 22. One end of the second suspension 3 is fixed to the sliding seat 23 on one side, and the other end is fixed to the sliding seat 23 on the other side. The sliding seat 23 can slide along the guide rod 22. By installing the second suspension 3 between the two sliding seats 23 and using the sliding fit of the sliding seat 23 and the guide rod 22, the second suspension 3 is provided with the ability of sliding adjustment.

[0033] Specifically, the mounting frame 4 includes vertical rods 41 respectively fixed on both sides of the upper surface of the first suspension 2 and vertically extending, and two cantilevers 42 respectively fixed on the tops of a pair of vertical rods 41. The cantilevers 42 are perpendicular to the extending direction of the first suspension 2. The auxiliary girder rail 5 is fixed on the two cantilevers 42. By using a pair of vertical rods 41 and a cantilever 42 to form a single-side frame body, and the two single-side frame bodies are symmetrically arranged to provide support for the installation of the auxiliary girder rail 5. By installing the auxiliary girder rail 5 on the two single-side frame bodies, the stability degree is high.

[0034] Specifically, the driving mechanism 6 includes a threaded rod 61, a driving motor 62, a nut seat 63 and a connecting arm 64. A guide groove 601 is provided below the auxiliary girder rail 5. The threaded rod 61 is rotatably installed in the guide groove 601. The driving motor 62 is fixed on one side of the auxiliary girder rail 5, and the output shaft of the driving motor 62 is fixedly connected to one end of the threaded rod 61. The nut seat 63 is limited and slidably installed in the guide groove 601 and is threadedly sleeved on the threaded rod 61. The top of the connecting arm 64 is fixed to the lower surface of the nut seat 63, and the top is fixedly connected to the top of the second suspension 3. By the operation of the driving motor 62, its output shaft drives the threaded rod 61 to rotate. The rotating threaded rod 61 threadedly drives the nut seat 63 to slide along the guide groove 601. Under the connection action of the connecting arm 64, the second suspension 3 can be driven to slide and adjust along the length direction of the first suspension 2, providing drive for the translation of the second suspension 3.

[0035] Specifically, second noise reduction plates 51 are respectively fixed on both sides of the secondary beam rail 5. Both second noise reduction plates 51 extend along the length direction of the secondary beam rail 5, and the bottom ends of both second noise reduction plates 51 extend below the secondary beam rail 5. By arranging the second noise reduction plates 51 on both sides of the secondary beam rail 5, a noise reduction effect can be provided when the driving mechanism 6 works, reducing the noise pollution generated during the operation of this crane.

[0036] Specifically, first noise reduction plates 31 are respectively fixed on both sides of the second suspension 3. Both first noise reduction plates 31 extend along the length direction of the second suspension 3, and the bottom ends of both first noise reduction plates 31 extend below the second suspension 3. By arranging the first noise reduction plates 31 on both sides of the second suspension 3, a noise reduction effect can be provided when the transverse movement assembly 8 and the suspension handling mechanism 9 work, further reducing the noise pollution generated during the operation of this crane.

[0037] Specifically, ball grooves 232 are evenly distributed on the inner wall of the sliding hole 231 of the sliding seat 23. The ball grooves 232 communicate with the sliding hole 231. Rolling balls 233 are respectively and rotatably installed in each ball groove 232. The rolling balls 233 are all exposed into the sliding hole 231 and are in contact with the outer wall of the guide rod 22. By evenly distributing the rolling balls 233 on the inner wall of the sliding hole 231 and using the rolling balls 233 to contact the guide rod 22, the contact surface is reduced. In addition, when the sliding seat 23 slides along the guide rod 22, the rolling balls 233 roll, greatly reducing the friction between the inner wall of the sliding hole 231 and the guide rod 22. This not only reduces the noise generated when the sliding seat 23 slides, but also ensures that the sliding of the sliding seat 23 is smooth and stable enough, killing two birds with one stone.

[0038] Specifically, this low-noise electric double-girder crane further includes four bases 11. The four bases 11 are all castings, with the bottom inserted into the ground and the top exposed above the ground. Fixed seats 111 are pre-embedded at the top ends of the four bases 11. Fastening seats 12 are respectively fixed at the bottom ends of the four columns 1. The four fastening seats 12 are fixedly connected to the four fixed seats 111 one by one through fastening bolts, ensuring the overall stability of the crane and at the same time enabling the bases 11 to be detachable, facilitating the later removal of the crane.
