Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a self-rotating gas cylinder sling with wide adaptability. Background Art

[0002] In production, gas cylinders need to be hoisted and sprayed. Among the prior art, spray hoisting gas cylinders include external force clamping methods and self-clamping methods. The external force clamping method is for example CN213171129U, a gas cylinder hoisting device, which discloses a gas cylinder hoisting device, including a lifting ring, an inner wall of the lifting ring is provided with an anti-slip ring, and a plurality of auxiliary clamping devices are evenly arranged on the circumferential surface of the lifting ring. The auxiliary clamping device includes a mounting seat, a clamping block hinged on the mounting seat, and a torsion spring symmetrically arranged on both sides of the clamping block, and a lifting ear is fixed on the top of the clamping block; a wear-resistant block is provided at one end of the clamping block close to the center of the lifting ring, and a plurality of first magnetic sheets are evenly arranged on the top of the lifting ring, and a second magnetic sheet that is attracted to the first magnetic sheet is correspondingly arranged at the bottom of the clamping block. When it is necessary to lift the gas cylinder, firstly, the steel wire rope is respectively inserted into the lifting ear, and then the lifting is performed. The clamping block clamps the outer wall of the gas cylinder at the same time under the tension of the steel wire rope, and the attraction of the wear-resistant block, the first magnetic sheet and the second magnetic sheet can increase the lifting time. Stability; after lifting, put down the wire rope, the clamping block is reset under the action of the torsion spring, and the friction block is separated from the gas cylinder. At this time, the lifting ring can be directly taken out. In this type of clamping method, multi-directional compression of the circumferential surface is required, and the wire rope needs to be inserted into the four lifting ears respectively. It needs to be pressed as straight as possible to make the force uniform, which makes the operation more difficult; the self-clamping method, for example, CN218261599U, a hydrogen gas cylinder lifting clamp, discloses a hydrogen gas cylinder lifting clamp, including a suspension rod, a movable bracket, an operating bracket, a connecting rod and a chuck. The movable bracket includes a sleeve and two cross bars symmetrically fixed on both sides of the sleeve. The suspension rod is inserted into the sleeve of the movable bracket. The operating bracket is divided into two groups. The upper ends of the two operating brackets are respectively rotatably connected to the ends of the two cross bars of the movable bracket away from the sleeve. The lower ends of the two operating brackets are fixed with chucks. The connecting rod is divided into two groups. The upper ends of the two connecting rods are rotatably connected to the lower ends of the suspension rods at one place, and the lower ends of the two connecting rods are respectively rotatably connected to the middle parts of the two operating brackets. After the hydrogen cylinder lifting fixture clamps the bottleneck of the hydrogen cylinder with two clamps, it can clamp itself under the action of the hydrogen cylinder's own weight. However, this type of solution needs to ensure effective clamping force around the bottle body. At the same time, when the bottle body is sprayed, the surface spraying treatment at the clamping position of the bottle body is limited, the uniformity of the paint film cannot be effectively controlled, and the spraying quality is unstable.

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Example

[0033] An embodiment of the present application provides a self-rotating gas cylinder hanger with wide adaptability to increase the convenience and uniformity of hanging spray bottles.

[0034] See also Figure 1 as well as Figure 2 The self-rotating wide-adaptability gas cylinder hanger provided in the embodiment of the present application includes a pull rod 100, a hanger block 200, a hanger ring 300 and a locking member 400;

[0035] The pull rod 100 is a threaded rod;

[0036] The hanging block 200 is hinged to the pull rod 100 through the core shaft 500. The hanging block 200 is divided into a first hanging block part and a second hanging block part with the core shaft 500 as a dividing line. The mass of the first hanging block part is greater than the mass of the second hanging block part. The hanging block 200 can rotate around the pull rod 100 with the core shaft 500 as an axis.

[0037] The lifting ring 300 is connected to the pull rod 100 and is far away from the lifting block 200. In some embodiments, the lifting block 200 is hinged to one end of the pull rod 100, and the lifting ring 300 is connected to the other end of the pull rod 100;

[0038] The locking member 400 is threadedly connected to the pull rod 100 and is located between the lifting ring 300 and the lifting block 200 to lock the lifting device and the bottle body. In some embodiments, the locking member 400 is a locking nut;

[0039] In some embodiments, the bottom of the pull rod 100 includes two relatively arranged connecting plates, and the hanging block 200 is located between the two connecting plates and hinged to the two connecting plates, so that when the pull rod 100 is parallel to the hanging block 200 and both are extended into the bottle body together, the hanging block 200 and the pull rod 100 are located in the same straight line, which reduces the overall size of the hanger and has better applicability. In some embodiments, the middle part of the hanging block 200 is hinged to the two connecting plates, and a baffle rod is provided between the two connecting plates. The hanging block 200 is provided with a clamping groove for clamping with the baffle rod. The hanging block 200 can rotate along the hinge position between the two connecting plates so that the baffle rod is clamped in the clamping groove. At this time, the hanging block 200 and the pull rod 100 are in the same straight line. When the tooling penetrates into the bottle body, the baffle rod can ensure that the hanging block 200 is in a vertical position and parallel to the pull rod 100, to prevent the hanging block 200 from hitting the bottom of the bottle or the bottle mouth from being scratched. In some embodiments, the baffle rod is provided above the hanging block 200.

[0040] In some embodiments, the middle of the hanging block 200 is hinged to the pull rod 100 through the core shaft 500. After the hanging block 200 is inserted into the bottle body, it can automatically rotate to a horizontal state due to gravity and abut the bottle body, so that the hanger is stuck to the bottle body.

[0041] In some embodiments, the mass of the second hanging block is no more than half of the mass of the first hanging block. After the hanging block 200 is inserted into the bottle body, it can automatically rotate to a horizontal state due to gravity and abut the bottle body, so that the hanger is stuck to the bottle body.

[0042] In some embodiments, the lifting ring 300 is connected to a lifting device to lift the bottle body to facilitate the next step of operation. In some embodiments, the lifting ring 300 is connected to a crane.

[0043] In some embodiments, the lifting ring 300 is provided with a connecting portion for connecting to the pull rod 100 , and the connecting portion is threadedly connected to the pull rod 100 to further fix the lifting ring 300 and the pull rod 100 .

[0044] In some embodiments, a plurality of locking members 400 are provided, which are spaced apart along the extension direction of the pull rod 100 to further enhance the locking effect between the hanger and the bottle body.

[0045] The lifting process of the self-rotating wide-adaptability gas cylinder lifting device of the present application is described in detail below:

[0046] See also Figure 3 When the self-rotating wide-adaptability gas cylinder hanger of the present application is used to act on the orifice of the gas cylinder, the hanger block 200 and the pull rod 100 are in a parallel state and extend into the orifice together. Because the hanger block 200 is divided into a first hanger block part and a second hanger block part by the core shaft 500, the mass of the first hanger block part is greater than the mass of the second hanger block part. After extending into the orifice, the hanger block 200 rotates along the core shaft 500 under the action of gravity due to the mass difference between the first hanger block part and the second hanger block part, pulling the lifting ring 300, so that the hanger block 200 can be abutted against the inner wall of the bottle, thereby lifting the bottle body. After the bottle body and the hanger are locked and fixed by the locking piece 400, the gas cylinder is lifted for spraying operation.

[0047] See also Figure 4 When the self-rotating wide-adaptability gas cylinder hanger of the present application is used to act on the mouth of the gas cylinder, the hanger block 200 and the pull rod 100 are in a parallel state and extend into the mouth of the bottle together. Because the core shaft 500 is used as a dividing line, the hanger block 200 is divided into a first hanger block part and a second hanger block part. The mass of the first hanger block part is greater than the mass of the second hanger block part. After extending into the mouth of the bottle, the hanger block 200 rotates along the core shaft 500 under the action of gravity due to the mass difference between the first hanger block part and the second hanger block part, pulling the lifting ring 300, so that the hanger block 200 can be abutted against the inner wall of the bottle, thereby lifting the bottle body. After the bottle body and the hanger are locked and fixed by the locking piece 400, the gas cylinder is lifted for spraying operation.

[0048] The self-rotating wide-adaptability gas cylinder hanger of the present application has at least the following advantages:

[0049] (1) The utility model uses a hinged hanging block and a pull rod. When in use, the hanging block and the pull rod are in a parallel state and are inserted into the bottle mouth together. Because the hanging block is divided into a first hanging block part and a second hanging block part by the core axis as a dividing line, the mass of the first hanging block part is greater than that of the second hanging block part. After being inserted into the bottle mouth, the hanging block rotates along the core axis under the action of gravity due to the mass difference between the first hanging block part and the second hanging block part, and the hanging ring is pulled, so that the hanging block can be abutted against the inner wall of the bottle, thereby lifting the bottle body. Compared with the prior art, the present application does not contact the outer side of the bottle body when in use, and does not affect the uniformity of spraying.

[0050] (2) The utility model locks the pull rod and the bottle body by a locking member, and there is no need to control the position of the bottle body, which is convenient to use.

[0051] (3) The utility model has reasonable design, simple structure and good practicality.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
