Description

Technical Field

[0001] This utility model belongs to the field of crane technology, and in particular relates to a special crane for mold production. Background Technology

[0002] Existing molds typically include an upper mold 16 and a lower mold 17. Currently, during the assembly and production of molds, the upper and lower molds need to be closed or separated multiple times. Then, depending on the closure situation, the upper and lower molds are adjusted separately. Since the upper mold has a certain weight, in the existing technology, a crane is usually used to lift and move the upper mold to complete the closure or separation between the upper and lower molds.

[0003] However, in actual use, since the crane lifts and lowers the upper mold by winding and unwinding the wire rope, the position of the upper mold is not fixed after the upper mold is separated from the lower mold, and it is prone to swaying. When the upper mold is being repaired, it is necessary to suspend and fix the position of the upper mold in order to facilitate the repair of the cavity inside the upper mold. However, the existing cranes do not have the function of suspending and fixing the upper mold. Sometimes, it is necessary for many people to support the upper mold to suspend and fix it, which is inconvenient to use. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a special crane for mold production to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A special crane for mold production includes a bridge crane body. A lifting trolley capable of moving along the bridge crane body is mounted on the bridge crane body. A first lifting mechanism with a first hook is mounted on the lifting trolley. A lifting device is attached to the first hook. The lifting device includes a horizontally positioned rectangular plate located below the bridge crane body. The rectangular plate is connected to the first hook. Displacement mechanisms are mounted on both sides of the rectangular plate along its length. The axial line of the displacement mechanism is parallel to the width direction of the rectangular plate. Each displacement mechanism has two sets of vertically opposite clamping arm mechanisms that can move closer or further apart. Vertically distributed multi-stage telescopic mechanisms are mounted on the outer sides of each clamping arm mechanism. The bottom end of each multi-stage telescopic mechanism is a movable end, and a support is mounted on the movable end of each multi-stage telescopic mechanism.

[0007] Furthermore, a telescopic mechanism is installed between the clamping arm mechanism and the multi-stage telescopic mechanism. Each telescopic mechanism includes a fixed seat installed on the outside of the clamping arm mechanism. A horizontally arranged electric telescopic rod is embedded in the fixed seat. The end of the electric telescopic rod away from the clamping arm mechanism is a movable end, which is connected to the multi-stage telescopic mechanism. A fixed rod parallel to the electric telescopic rod is installed on the side of the multi-stage telescopic mechanism near the fixed seat. The fixed rod and the fixed seat are slidably connected.

[0008] Furthermore, the crane trolley is equipped with a second lifting mechanism with a second hook, and a lifting ring capable of engaging with the second hook is installed on one side of the rectangular hanging plate along its length.

[0009] Furthermore, each displacement mechanism includes two support seats, which are symmetrically arranged on both sides of the rectangular hanging plate in the width direction. Two horizontally opposite guide rods are fixedly connected between the two support seats. A lead screw is installed between the two guide rods and is parallel to the guide rods. Both ends of the lead screw are rotatably connected to the support seats, and a displacement motor is driven to the lead screw. The threads at both ends of the lead screw have opposite directions. Movable seats are also sleeved and threaded to both ends of the lead screw. Both sides of the movable seats are sleeved on the guide rods and slidably connected to the guide rods. The clamping arm mechanism is respectively installed on the movable seats.

[0010] Furthermore, each of the clamping arm mechanisms includes a clamping arm vertically mounted on a movable seat, and a clamp is installed on the inner side of each clamping arm.

[0011] Furthermore, the bottom surface of the support is serrated.

[0012] Furthermore, the bridge crane body includes two horizontally opposite main beams. Each main beam is equipped with an I-shaped track for the movement of the crane trolley. Both ends of each main beam are equipped with horizontally arranged end beams that are perpendicular to the main beams. Both ends of the end beams are equipped with trolley traveling mechanisms. A connecting beam is provided between the two end beams located at the same end of the main beams. Both ends of the connecting beam are connected to the trolley traveling mechanisms.

[0013] Furthermore, the multi-stage telescopic mechanism is a multi-stage telescopic hydraulic cylinder.

[0014] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0015] Based on the existing bridge crane body, lifting trolley and first lifting mechanism, this utility model can be used to lift the upper mold by setting up a lifting device. Specifically, in use, by setting up a displacement mechanism, the two sets of clamping arm mechanisms on the displacement mechanism can be driven to move closer to each other until the clamping arm mechanisms respectively abut against the upper mold, and the four corners of the upper mold can be clamped and fixed. Then, when the upper mold is lifted to a suitable height position by the first lifting mechanism, the extension of the multi-stage telescopic mechanism can make the supports press against the ground to support the upper mold together. At this time, the position of the upper mold can be suspended and fixed, which makes it easy to adjust the upper mold. Attached Figure Description

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 5As shown, this utility model provides a special crane for mold production, including a bridge crane body 6. A lifting trolley 9, capable of moving along the bridge crane body 6, is mounted on the bridge crane body 6. Specifically, the lifting trolley 9 is existing technology. The bridge crane body 6 includes two horizontally opposite main beams 61. Each main beam 61 is equipped with an I-beam track for the movement of the lifting trolley 9. Each main beam 61 has horizontally arranged end beams 62 perpendicular to the main beam 61 at both ends. Each end beam 62 has a... The trolley traveling mechanism 63 includes wheel frames, traveling wheels, and drive units. During operation, since two sets of trolley traveling mechanisms 63 are installed at the ends of each main beam 61 (i.e., trolley traveling mechanisms 63 are installed at the four corners of each main beam 61), the bridge crane body 6 becomes more stable during movement. Furthermore, a connecting beam 64 is provided between the two end beams 62 located at the same end of the main beam 61, with both ends of the connecting beam 64 connected to the trolley traveling mechanism 63, facilitating connection between the two main beams 61.

[0024] The trolley 9 is equipped with a first lifting mechanism 10 with a first hook. The first lifting mechanism 10 also includes a drum, wire rope, driver, and reducer. A lifting device is attached to the first hook. In use, the lifting device can be used to lift the upper mold 16. The first lifting mechanism 10 can drive the upper mold 16 to move up and down. Through the movement of the bridge crane body 6 and the trolley 9, the upper mold 16 can be moved forward, backward, left, and right. The lifting device includes a rectangular lifting plate 5 that is horizontally set and located below the bridge crane body 6. The rectangular lifting plate 5 is attached to the first hook. Specifically, lifting lugs 11 are fixedly connected to the four corners of the top surface of the rectangular lifting plate 5. Each lifting lug 11 is equipped with a lifting rope 12. The ends of the four lifting ropes 12 away from the lifting lugs 11 are connected to a ring rope 13 that can be attached to the first hook. In this way, the first lifting mechanism 10 lifts the rectangular lifting plate 5 from four points.

[0025] In addition, displacement mechanisms 4 are installed on both sides of the rectangular hanging plate 5 along its length. The axial line of the displacement mechanism 4 is parallel to the width direction of the rectangular hanging plate 5. Each displacement mechanism 4 is equipped with two sets of vertically opposite clamping arm mechanisms 3 that can move closer or further apart from each other. In the initial state, the clamping arm mechanisms 3 are located outside the upper mold 16. Vertically distributed multi-stage telescopic mechanisms 2 are installed on the outer side of each clamping arm mechanism 3. The bottom end of the multi-stage telescopic mechanism 2 is the movable end, and the movable end of the multi-stage telescopic mechanism 2 is equipped with a support 1. Specifically, the multi-stage telescopic mechanism 2 can be set as a multi-stage telescopic hydraulic cylinder, and the multi-stage telescopic mechanism 2 is externally connected to a power source installed on the outer side of the clamping arm mechanism 3. In use, when using the bridge crane body 6 and the lifting trolley When the first lifting mechanism 10 moves the rectangular hanging plate 5 above the upper mold 16, the two sets of clamping arm mechanisms 3 on each set of displacement mechanisms 4 are located outside the upper mold 16. Then, through the displacement mechanism 4, the two sets of clamping arm mechanisms 3 on the displacement mechanism 4 can be moved closer to each other until the clamping arm mechanisms 3 respectively abut against the upper mold 16, and the four corners of the upper mold 16 can be clamped and fixed. Then, when the first lifting mechanism 10 drives the upper mold 16 to a suitable height position, the multi-stage telescopic mechanism 2 can be extended directly or after the upper mold 16 is moved to another place until the support 1 is pressed against the ground, so that the upper mold 16 can be supported together. At this time, the position of the upper mold 16 can be suspended and fixed, which makes it easy to adjust the upper mold 16.

[0026] Furthermore, such as Figures 1 to 4 As shown, a telescopic mechanism 7 is installed between the clamping arm mechanism 3 and the multi-stage telescopic mechanism 2. Each telescopic mechanism 7 includes a fixed base 71 installed on the outside of the clamping arm mechanism 3. A horizontally arranged electric telescopic rod 72 is embedded in the fixed base 71. The end of the electric telescopic rod 72 away from the clamping arm mechanism 3 is a movable end, which is connected to the multi-stage telescopic mechanism 2. Specifically, the electric telescopic rod 72 can be configured as a hydraulic cylinder. In use, the electric telescopic rod 72 and the multi-stage telescopic mechanism 2 can share a power source and extend and retract separately. Specifically, before the multi-stage telescopic mechanism 2 extends, it is powered by an electric... The extension of the telescopic rod 72 allows the multi-stage telescopic mechanism 2 to move away from the clamping arm mechanism 3. This ensures sufficient space for movement below the upper mold 16 after it is suspended and fixed, facilitating the movement of production personnel. Furthermore, a fixed rod 14 parallel to the electric telescopic rod 72 is installed on the side of the multi-stage telescopic mechanism 2 near the fixed base 71. The fixed rod 14 is slidably connected to the fixed base 71. Specifically, the fixed rod 14 is slidably connected to the fixed base 71 through a through hole. By setting the fixed rod 14, the stability of the multi-stage telescopic mechanism 2 during movement can be improved.

[0027] Furthermore, such as Figure 1 and Figure 4As shown, the trolley 9 is equipped with a second lifting mechanism 8 with a second hook. The second lifting mechanism 8 also includes a drum, wire rope, driver, and reducer. A lifting ring 15 that can be hooked with the second hook is installed on one side of the rectangular lifting plate 5 along its length. Specifically, after the upper mold 16 is raised to a suitable height by the first lifting mechanism 10, the upper mold 16 can be moved to another location by the trolley 9 or the bridge crane body 6. Then, the upper mold 16 is lowered to a certain height so that the second hook on the second lifting mechanism 8 can be hooked with the lifting ring 15. At this time, the wire rope is wound up by the second lifting mechanism 8, which can cause the upper mold 16 to rotate at a certain angle and be tilted. When the upper mold 16 is lowered by the second lifting mechanism 8 and the first lifting mechanism 10, the lower side of the upper mold 16 can touch the ground for auxiliary fixation. This also makes it easier to adjust the upper mold 16. In addition, it is also easier to clean the impurities attached to the upper mold 16.

[0028] The specific configuration of displacement mechanism 4 is as follows: Figures 1 to 4 As shown, each displacement mechanism 4 includes two support seats 41, which are symmetrically arranged on both sides of the rectangular hanging plate 5 in the width direction. Two horizontally opposite guide rods 42 are fixedly connected between each support seat 41. A lead screw 43, parallel to the guide rods 42, is installed between each of the two guide rods 42. Both ends of the lead screw 43 are rotatably connected to the support seat 41, and a displacement motor 44 is driven and connected to the lead screw 43. Specifically, the middle position of the lead screw 43 is a shaft, and it is driven and connected to a mechanism 46 mounted on the rectangular hanging plate 5 via a bevel gear transmission mechanism 46. The displacement motor 44 is a forward and reverse rotating motor; the threads at both ends of the lead screw 43 are turned in opposite directions, and both ends of the lead screw 43 are fitted with and threadedly connected to movable seats 45. Both sides of the movable seats 45 are fitted on the guide rod 42 and slidably connected to the guide rod 42. The clamping arm mechanisms 3 are respectively installed on the movable seats 45. Specifically, when the displacement motor 44 is started, it can drive the movable seats 45 at both ends of the lead screw 43 to move closer or further away from each other along the guide rod 42, thereby driving the two sets of clamping arm mechanisms 3 on the same set of displacement mechanisms 4 to move closer or further away from each other.

[0029] The specific configuration of the clamping arm mechanism 3 is as follows: Figures 1 to 4 As shown, each clamping arm mechanism 3 includes a clamping arm 31 vertically mounted on the movable seat 45. Each clamping arm 31 has a clamping clamp 32 mounted on its inner side. Specifically, the clamping arms 31 can move closer or further apart from each other under the drive of the displacement mechanism 4. When the clamping clamp 32 is pressed against the upper mold 16, the upper mold 16 can be clamped. In addition, since the two sets of clamping arm mechanisms 3 on each set of displacement mechanism 4 can move closer or further apart from each other, it is also convenient to clamp and fix upper molds 16 of different widths.

[0030] Furthermore, such as Figures 1 to 4As shown, the bottom surface of the support 1 is serrated, which can improve the grip of the support 1 during use and prevent the support 1 from slipping, thereby improving the stability of the upper mold 16 when it is suspended and fixed.
