Description

Technical Field

[0001] This application relates to the field of transportation technology, and in particular to a hoisting device for a mold frame. Background Technology

[0002] The mold frame is made of alloy material, and many mold frames are quite large, so they are very heavy. When moving or assembling them, hoisting equipment is required. Common hoisting equipment includes mobile cranes and rollers fixed to the top of the factory building. Although the former is easy to move, it takes up a lot of space and is difficult to use indoors. Although the latter can be operated indoors, the setup cost is high. In addition, both methods require the use of hooks, which requires workers to fasten or remove the hooks, making the operation cumbersome and also posing certain dangers. Summary of the Invention

[0003] The purpose of this application is to provide a hoisting device for mold frames that is more convenient to use.

[0004] To achieve the above objectives, this application provides a hoisting device for a mold frame: including a frame, a driver is provided at the top of the frame, the driver includes a traction cabin, a suspension cable is wound inside the traction cabin, a configuration frame is connected to the lower end of the suspension cable, a bidirectional telescopic rod is fixedly connected to the bottom of the configuration frame, a first hanger and a second hanger are respectively connected to the two movable ends of the bidirectional telescopic rod, the first hanger and the second hanger are provided with cantilever arms and guardrails that can be interlocked on opposite sides, the cantilever arms are adapted to support the bottom of the mold frame, the guardrails are adapted to block the sides of the mold frame, and the lower end of the frame is also provided with casters for easy transfer on flat ground.

[0005] As a preferred embodiment, the configuration frame includes a lifting platform fixedly connected to the lower end of the suspension cable. The lifting platform is fixedly connected to the cylinder of the bidirectional telescopic rod via a mounting plate to ensure the stability of the center position of the bidirectional telescopic rod.

[0006] As a preferred embodiment, a sliding rod is fixedly connected to the side of the mounting plate. The first hanger includes a first sliding plate with a first sliding hole for the sliding rod to pass through and form a sliding pair. The second hanger includes a second sliding plate with a second sliding hole for another set of sliding rods to pass through and form a sliding pair, thus sharing the load on the telescopic rod and ensuring the stability of the sliding plate's movement.

[0007] As a preferred embodiment, a first cantilever is fixedly connected to the side of the first skateboard, and an insertion port is provided at the end of the first cantilever. A second cantilever is fixedly connected to the side of the second skateboard, and an insertion plate is provided at the end of the second cantilever, which is suitable for insertion and engagement with the insertion port to ensure the stability of the cantilever end.

[0008] As a preferred embodiment, a first guardrail is fixedly connected to the side of the first slide plate. The first guardrail is higher than the first cantilever and has a pin plate at its end. A second guardrail is fixedly connected to the side of the second slide plate. The second guardrail is also higher than the second cantilever and has a pin hole at its end, which is suitable for insertion and engagement with the pin plate to ensure the stability of the guardrail end.

[0009] As a preferred embodiment, a limiting plate is fixedly connected to the end of the slide rod away from the mounting plate, and the limiting plate is also fixedly connected to the lifting platform to enhance the stability of the end of the slide rod.

[0010] As a preferred embodiment, the equipment rack includes a pair of legs, the upper ends of which are fixedly connected to a guide rail. The drive unit also includes a sliding platform fixedly connected to the traction cabin. The sliding platform has a guide hole on its side, which is suitable for the guide rail to pass through to form a sliding pair, so that the position of the configuration rack can be finely adjusted when the position of the equipment rack remains unchanged.

[0011] As a preferred embodiment, the lower end of the support leg is fixedly connected to a base beam, and the casters are disposed on the lower surface of the base beam to ensure the stability and flexibility of the equipment frame.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a cantilever and railing structure that can automatically retract and release, the hook structure of the traditional hoisting equipment is replaced. This not only eliminates the need for manual hooking and unhooking operations, making the hoisting process more efficient and safe, but also increases the contact area between the cantilever and railing and the mold frame, making it easier to maintain the stability of the mold frame during hoisting. In addition, there are interlocking structures designed between the cantilever and railing, which also makes the structural stability of the equipment itself relatively high during hoisting.

[0014] (2) The design is small in size, flexible and convenient, and has low operating costs. It can be used both indoors and outdoors. Attached Figure Description

[0022] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0024] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0026] like Figure 1-6 The hoisting equipment for the mold frame shown includes a frame 1 welded from square steel pipes. The frame 1 is similar in shape to a gantry crane. A drive unit 2 is installed on the top of the frame 1 to provide power for hoisting the mold frame. The specific structure of the drive unit 2 includes a traction cabin 203, which is a rope winding and unwinding mechanism. Suspension cables 204 are wound inside the traction cabin 203. The suspension cables 204 are generally made of nylon fiber and have very high wear resistance and tensile strength. There are at least three suspension cables 204, all of which move up and down under the drive of the traction cabin 203. The lower ends of these suspension cables 204 are connected to a configuration frame 5. Therefore, the tilt angle of the configuration frame 5 relative to the horizontal plane is adjustable and has high flexibility. However, under normal circumstances, the configuration frame 5 only needs to be kept horizontal.

[0027] A bidirectional telescopic rod 6 is fixedly connected to the bottom of the mounting frame 5. It typically uses a fast-responding bidirectional telescopic cylinder. The two movable ends of the bidirectional telescopic rod 6 are respectively connected to a first hanger 3 and a second hanger 4, which work together to grip the mold frame. The mounting frame 5 includes a lifting platform 501 fixedly connected to the lower end of a suspension cable 204. Several suspension cables 204 are respectively connected to the corner positions on the upper surface of the lifting platform 501. The lifting platform 501 is fixedly connected to the cylinder body of the bidirectional telescopic rod 6 via a mounting plate 502. There are usually two bidirectional telescopic rods 6, connected to the same pneumatic system, enabling synchronous telescopic movement. A sliding rod 503 is fixedly connected to the side of the mounting plate 502. The sliding rod 503 is divided into two groups, located opposite each other on the mounting plate 502. On both sides, and parallel to the extension and retraction direction of the bidirectional telescopic rod 6, the first hanger 3 includes a vertical first sliding plate 301, on which a first sliding hole 302 with a horizontal axis is opened for the sliding rod 503 to pass through to form a sliding pair; the second hanger 4 includes a second sliding plate 401 parallel to the first sliding plate 301, on which a second sliding hole 402 with the same horizontal axis is opened for another set of sliding rods 503 to pass through to form a sliding pair. The end of the sliding rod 503 away from the mounting plate 502 is fixedly connected to a limiting plate 504 to prevent the sliding plate from detaching from the sliding rod 503. The limiting plate 504 is also fixedly connected to the lifting platform 501 to provide a diagonal pulling force to the end of the sliding rod 503, thereby ensuring the straightness of the sliding rod 503.

[0028] The first hanger 3 and the second hanger 4 have interlocking cantilever arms and guardrails on opposite sides. The cantilever arms support the bottom of the mold frame, while the guardrails protect the sides of the mold frame. This ensures the mold frame between the first hanger 3 and the second hanger 4 remains very stable after lifting. Specifically, the first slide plate 301 is fixedly connected to the side of the first cantilever arm 303, and the end of the first cantilever arm 303 has a central insertion slot 304. The second slide plate 401 is fixedly connected to the side of the second cantilever arm 403, which is collinear with the first cantilever arm 303. The end of the second cantilever arm 403 has a central insertion slot 404, which interlocks with the insertion slot 304. 4. The plug-in fit: The plugged-in plate 404 can reduce the descent of the cantilever when it is under pressure. The side of the first slide plate 301 is also fixedly connected to the first guardrail 305. The first guardrail 305 is significantly higher than the first cantilever 303. The end of the first guardrail 305 has a pin plate 306 at the center. The side of the second slide plate 401 is also fixedly connected to the second guardrail 405, which is collinear with the first guardrail 305. The second guardrail 405 is also significantly higher than the second cantilever 403. The end of the second guardrail 405 has a pin hole 406 at the center, which is plugged into the pin plate 306. The plugged-in pin plate 306 can reduce the outward bulge of the guardrail when it is subjected to lateral tilting pressure.

[0029] The equipment frame 1 includes a pair of symmetrical support legs 101, which form a cuboid shape. The upper ends of the two support legs 101 are fixedly connected to a pair of parallel guide rails 102, both of which are horizontal. The drive unit 2 also includes a sliding stage 201 fixedly connected to the traction chamber 203. The sliding stage 201 has a built-in servo motor. Guide holes 202 are provided on the side of the sliding stage 201 for the guide rails 102 to pass through, forming a sliding pair. The side of the guide rails 102 typically also has a toothed structure that meshes with a gear connected to the output end of the servo motor, thereby allowing the sliding stage 201 to move. 01 can be adjusted on the guide rail 102 by means of electric control. The lower end of the equipment frame 1 is also provided with casters 104. In fact, the lower end of the support leg 101 is fixedly connected to the bottom beam 103 to ensure the structural stability of the support leg 101 on one side. When the support legs 101 on both sides are not connected to any structure at the lower end, it is convenient for the entire equipment frame 1 to straddle the mold frame. The casters 104 are set on the lower surface of the bottom beam 103. At least three are needed to ensure the stability of the equipment frame 1. In this embodiment, four are set, which are located at the four corners at the bottom of the equipment frame 1.

[0030] Working principle: In the initial state, the configuration frame 5 is at its upper limit position, and the first gantry 3 and the second gantry 4 are far apart. The mobile equipment frame 1 is moved above the mold frame. Then, the suspension cable 204 in the traction cabin 203 extends, causing the first gantry 3 and the second gantry 4 to descend to a suitable height, positioning the mold frame between the cantilever and the guardrail. Then, the bidirectional telescopic rod 6 retracts, and the first cantilever 303 and the second cantilever 403 pass under the suspended bottom surface of the mold frame and engage. At the same time, the first guardrail 305 and the second guardrail 405 block the outer side of the mold frame and engage. Finally, the suspension cable 204 is retracted, and the mold frame rises with the configuration frame 5 to a suitable height, ready for transfer. When releasing the mold frame, it needs to be lowered and stabilized. Then, the first gantry 3 and the second gantry 4 move away from each other under the action of the bidirectional telescopic rod 6. Once the cantilever and guardrail no longer interfere with the mold frame in the vertical direction, the configuration frame 5 returns to its upper limit position under the action of the suspension cable 204, ready for the next round of hoisting work.
