Description

Technical Field

[0001] The utility model relates to the technical field of crane counterweight devices, in particular to a counterweight stabilizing device for a jib crane. Background Technique

[0002] The jib crane is a small and medium-sized lifting equipment developed in recent years. It has a unique structure, is safe and reliable, and has the characteristics of high efficiency, energy saving, time and labor saving, and flexibility. It can be operated arbitrarily in three-dimensional space. In the case of short-distance and intensive lifting, it shows more superiority than other conventional lifting equipment. At the same time, the jib crane is a device used for short-distance, frequent, and intensive lifting operations.

[0003] The prior art patent document with the publication number of CN219730376U provides a crane counterweight device, including a crane chassis, a first counterweight plate, and a second counterweight plate. A lifting component is provided on the crane chassis, and two counterweight placement plates are fixedly installed on the top side of the crane chassis. Counterweight conveying cross bars are fixedly installed on the top sides of the two counterweight placement plates. For this crane counterweight device, when lifting a heavy object, it is necessary to add counterweight equipment on the crane chassis to increase the stability of the crane. When it is necessary to add counterweight equipment, start the conveying control board. Under the action of the conveying component, the movement of the conveying control board can be realized. When it moves above the second counterweight plate on the outer ground, the rotating motor on the counterweight lifting component will be transported to operate. The operation of the rotating motor drives the lifting roller to rotate, and the lifting cable will move downward. Two hooks are provided at the bottom end of the lifting cable and are hung on the second counterweight plate.

[0004] However, in the process of using the existing counterweight stabilizing device for a jib crane, for some movable jib cranes, due to the center of gravity of the jib crane shifting to one side, the jib crane needs to be counterweighted when lifting after being installed. When lifting without counterweight, tipping will occur, resulting in the need to install counterweights before the jib crane starts to lift, leading to the problem of poor practicability of the jib crane. For this reason, we propose a counterweight stabilizing device for a jib crane. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a counterweight stabilizing device for a jib crane, which includes a mounting base 1. An adjustment opening 2 is provided on one side of the mounting base 1. An adjustment support arm 3 is movably connected to one side of the mounting base 1 through the adjustment opening 2. Adjustment plates 5 are fixedly connected to both the front and back of the mounting base 1. An adjustment shaft 6 is fixedly connected through the top of the adjustment plate 5. A balance arm 7 is movably connected to the outer side of the adjustment shaft 6. A counterweight arm 8 is fixedly connected to the other side of the mounting base 1. A storage groove 11 is provided at the top of the counterweight arm 8. A main guard bar 12 is movably connected to the top of the counterweight arm 8 through the storage groove 11. A guard bar groove 9 is provided on the front of the counterweight arm 8. A side guard bar 10 is movably connected to the front of the counterweight arm 8 through the guard bar groove 9.

[0024] In this embodiment, specifically, moving wheels 4 are fixedly connected to the bottoms of the mounting base 1, the adjustment support arm 3, the balance arm 7, and the counterweight arm 8. There are two adjustment support arms 3, balance arms 7, and counterweight arms 8 respectively. The counterweight stabilizing device can be easily moved through the moving wheels 4, enabling the counterweight stabilizing device to be moved to the installation position.

[0025] In this embodiment, specifically, there are ten moving wheels 4. Four of the moving wheels 4 are located at the four corners of the bottom of the mounting base 1, and the other six moving wheels 4 are respectively located at the bottoms of the two adjustment support arms 3, balance arms 7, and counterweight arms 8. The counterweight stabilizing device can be easily moved through the moving wheels 4, enabling the counterweight stabilizing device to be moved to the installation position.

[0026] In this embodiment, specifically, the inner width of the adjustment opening 2 is adapted to the outer width of the adjustment support arm 3. The adjustment opening 2 is movably connected to the adjustment support arm 3. Pulling the adjustment support arm 3 out of the adjustment opening 2 can play a role in increasing stability.

[0027] In this embodiment, specifically, the mounting base 1, the adjustment support arm 3, the balance arm 7, and the counterweight arm 8 are all processed from carbon steel materials. The outer surfaces of the mounting base 1, the adjustment support arm 3, the balance arm 7, and the counterweight arm 8 are smooth. The mounting base 1, the adjustment support arm 3, the balance arm 7, and the counterweight arm 8 processed from carbon steel materials are more durable and not easily damaged.

[0028] In this embodiment, specifically, there are four side guard bars 10. Every two of the four side guard bars 10 form a group. The lengths of the four side guard bars 10 are the same. Pulling out the side guard bars 10 on the guard bar groove 9 can make the side guard bars 10 play a protective role when the counterweight is installed on the counterweight arm 8.

[0029] Working principle: After the utility model is installed, first check the installation and fixation as well as the safety protection of the utility model. When using the counterweight stabilizing device of the jib crane, the staff installs the jib crane on the mounting base 1. After installation, the jib crane can be moved to the working position through the counterweight stabilizing device. When the jib crane is lifting an object, the staff pulls out the adjusting support arm 3 from the adjusting opening 2, and then pulls the balance arm 7. The balance arm 7 can be movably connected through the adjusting shaft 6 at the bottom of the adjusting plate 5, so that the counterweight stabilizing device forms a cross structure to play a stabilizing role. When the jib crane is lifting an object, even without counterweight, it can lift an object of a certain weight and perform 360-degree rotational transportation. When the jib crane is lifting a relatively heavy object, the user can pull out the side guard bar 10 on the guard bar groove 9, then pull out the main guard bar 12 in the storage groove 11, and place the counterweight block on the counterweight arm 8 for counterweight. In this way, the use process of the utility model is completed. The utility model has a simple structure and is safe and convenient to use.
