Description

Technical Field

[0001] This utility model relates to the field of suspended crane technology, specifically to a suspended crane that operates stably. Background Technology

[0002] The full name of a suspension crane is flexible, lightweight, and modular suspension crane. It is also a type of light and small lifting equipment. There are two types of suspension cranes: single beam and double beam. The main advantages include a lifting capacity of up to 2000 kg, easy installation, and safety.

[0003] To avoid disrupting operations, a flexible, lightweight, modular beam suspension crane is a perfect choice when a work area cannot accommodate any supporting structures. This crane system requires a roof structure strong enough to safely support the crane's load. Customers can install multiple main beams on a single fixed rail, significantly improving production efficiency. However, existing suspension cranes are prone to vibration at their connections, leading to bolt loosening and connection instability over long-term use. Therefore, a stable suspension crane is urgently needed to overcome these shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a stable overhead crane with high stability and vibration resistance, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable suspended crane, comprising a suspended crane body, an outer mounting assembly, a movable vibration damping assembly, a top mounting assembly, and slide rails. The slide rails slide on both sides of the suspended crane body. The outer mounting assemblies are disposed on both sides of the slide rails. The top mounting assemblies are disposed on both sides of the top of the slide rails. The movable vibration damping assembly is disposed on the top of the slide rails. The outer mounting assembly includes a first mounting block, a square rubber pad, a first mounting hole, a circular rubber pad, a second mounting block, and a second mounting hole. The movable vibration damping assembly includes a fixed plate, a circular plate, a damping shock absorber, a U-shaped seat, a slide rod, a slide groove, a positioning plate, a threaded rod, and a turntable. The top mounting assembly includes a connecting rod and a mounting base.

[0006] Furthermore, the first mounting blocks are fixedly installed on both sides of the slide rail, and the first mounting blocks have first mounting holes on both sides inside. Two square rubber pads are fixedly installed on the side of the first mounting block that is relatively far away from each other.

[0007] Furthermore, a second mounting block is fixedly mounted on the outer side of the first mounting block, and a circular rubber pad is fixedly mounted on the outer side of the second mounting block. The second mounting block has four second mounting holes inside, and the connecting rods are all fixedly mounted on both sides of the top of the slide rail.

[0008] Furthermore, a mounting base is fixedly installed on the top of the connecting rod, the U-shaped seat is fixedly installed at the center of the top of the slide rail, a positioning plate is provided in the inner cavity of the U-shaped seat, and sliding grooves are provided on both sides inside the U-shaped seat.

[0009] Furthermore, a slide rod is slidably connected inside the slide groove, a fixing plate is fixedly installed on the top of the slide rod, the bottom of the slide rod is fixedly connected to the top of the positioning plate, and the threaded rod rotates inside the positioning plate through the thread.

[0010] Furthermore, the bottom of the threaded rod is rotatably connected to the top of the slide rail via a bearing, the turntable is set on the top of the U-shaped seat, and the top of the threaded rod extends through to the top of the U-shaped seat and is fixedly connected to the bottom of the turntable.

[0011] Furthermore, four damping shock absorbers are fixedly installed on the top of the fixed plate, and a circular plate is fixedly installed on the top of each damping shock absorber.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This utility model uses a suspended crane body to lift and transfer heavy objects. A slide rail limits the movement of the suspended crane body, preventing swaying during movement. A moving vibration damping component buffers and reduces vibration at the top of the slide rail. External and top mounting components secure the slide rail and improve its stability. During installation, bolts are first used to fix the first and second mounting blocks through the first and second mounting holes, respectively. Simultaneously, circular and square rubber pads seal the gaps between the first and second mounting blocks and the object being installed, achieving further buffering and vibration reduction. Next, the bolts are fixed to the object using mounting seats. To ensure stability, a turntable is rotated, causing the threaded rod to rotate. This moves the positioning plate and the slide rod upwards. Once at the designated position, the damping shock absorber ensures the circular plate is tightly against the top of the object, further improving the stability of the suspended crane body during operation. This design offers high stability and vibration resistance, solving the problems of vibration at the connection points and bolt loosening / unstable connections in existing suspended cranes after prolonged use.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides, for example Figure 1-4 As shown, a stable suspended crane includes a suspended crane body 1, an outer mounting assembly 2, a movable vibration damping assembly 3, a top mounting assembly 4, and a slide rail 5. The slide rail 5 slides on both sides of the suspended crane body 1. The outer mounting assembly 2 is disposed on both sides of the slide rail 5. The top mounting assembly 4 is disposed on both sides of the top of the slide rail 5. The movable vibration damping assembly 3 is disposed on the top of the slide rail 5. The outer mounting assembly 2 includes a first mounting block 21, a square rubber pad 22, a first mounting hole 23, a circular rubber pad 24, a second mounting block 25, and a second mounting hole 26.

The top mounting assembly 4 includes a connecting rod 41 and a mounting seat 42.

[0021] More specifically, the slide rail 5 is fixed by setting the outer mounting component 2 and the top mounting component 4, thereby improving the stability of the slide rail 5. During installation, the bolts first fix the first mounting block 21 and the second mounting block 25 through the first mounting hole 23 and the second mounting hole 26, respectively. At the same time, the gaps at the connection between the second mounting block 25 and the first mounting block 21 and the installation object are sealed by the action of the circular rubber pad 24 and the square rubber pad 22, thereby achieving the purpose of buffering and shock absorption. Then, the bolts are fixed to the installation object through the mounting seat 42. After fixing, in order to ensure its stability, the turntable 39 is rotated. The turntable 39 drives the threaded rod 38 to rotate, so that the positioning plate 37 drives the slide rod 35 to move upward. After moving to the designated position, the circular plate 32 is pressed tightly against the top of the installation object by the action of the damping shock absorber 33, which further improves the stability of the suspended crane body 1 during operation and has the advantages of high stability and vibration resistance.

[0022] In some embodiments, the first mounting blocks 21 are fixedly mounted on both sides of the slide rail 5. The first mounting blocks 21 have first mounting holes 23 on both sides inside. Two square rubber pads 22 are fixedly mounted on the side of the first mounting blocks 21 that is relatively far apart. More specifically, by setting the first mounting holes 23 and the second mounting holes 26, bolts can pass through the interior of the first mounting blocks 21 and the second mounting blocks 25, thereby connecting and fixing them.

[0023] In some embodiments, a second mounting block 25 is fixedly mounted on the outer side of the first mounting block 21, and a circular rubber pad 24 is fixedly mounted on the outer side of the second mounting block 25. The second mounting block 25 has four second mounting holes 26 inside. The connecting rods 41 are all fixedly mounted on both sides of the top of the slide rail 5. More specifically, by setting the circular rubber pad 24 and the square rubber pad 22, the existing gaps are mainly buffered and the stability is improved.

[0024] In some embodiments, a mounting base 42 is fixedly installed on the top of the connecting rod 41, and the U-shaped seat 34 is fixedly installed at the center of the top of the slide rail 5. A positioning plate 37 is provided in the inner cavity of the U-shaped seat 34, and sliding grooves 36 are provided on both sides inside the U-shaped seat 34. More specifically, the mounting base 42 is fixed by setting the connecting rod 41, and the top of the slide rail 5 is fixed by bolts.

[0025] In some embodiments, a slide rod 35 is slidably connected inside the slide groove 36, a fixing plate 31 is fixedly installed on the top of the slide rod 35, the bottom of the slide rod 35 is fixedly connected to the top of the positioning plate 37, and the threaded rod 38 rotates inside the positioning plate 37 by thread. More specifically, the slide groove 36 is used to limit the slide rod 35 to prevent it from shaking during movement, and the slide rod 35 is used to limit the fixing plate 31.

[0026] In some embodiments, the bottom of the threaded rod 38 is rotatably connected to the top of the slide rail 5 via a bearing, the turntable 39 is disposed on the top of the U-shaped seat 34, and the top of the threaded rod 38 extends through to the top of the U-shaped seat 34 and is fixedly connected to the bottom of the turntable 39. More specifically, the turntable 39 is used to drive the threaded rod 38, thereby causing the positioning plate 37 to drive the slide rod 35 to move upward.

[0027] In some embodiments, four damping shock absorbers 33 are fixedly installed on the top of the fixed plate 31, and a circular plate 32 is fixedly installed on the top of the damping shock absorber 33. More specifically, by setting the damping shock absorber 33 and the circular plate 32, the gap between the fixed plate 31 and the installed object is mainly buffered and damped, and its vibration is prevented.

[0028] Working principle:

[0029] Step 1: During installation, the bolts are first used to fix the first mounting block 21 and the second mounting block 25 through the first mounting hole 23 and the second mounting hole 26 respectively. At the same time, the gaps at the connection between the second mounting block 25 and the first mounting block 21 and the installation are sealed by the circular rubber pad 24 and the square rubber pad 22, so as to achieve the purpose of buffering and shock absorption.

[0030] Step 2: Next, fix the bolts to the installation object through the mounting base 42. After fixing, in order to ensure its stability, rotate the turntable 39. The turntable 39 drives the threaded rod 38 to rotate, so that the positioning plate 37 drives the sliding rod 35 to move upward. After moving to the designated position, under the action of the damping shock absorber 33, the circular plate 32 is tightly attached to the top of the installation object, which further improves the stability of the suspended crane body 1 during operation. It has the advantages of high stability and vibration resistance.
