Description

Technical Field

[0001] The present application relates to the field of thermal pipeline hoisting, and in particular to a thermal pipeline hoisting device. Background Art

[0002] Thermal pipelines are heating pipelines that start from boiler rooms, direct-fired engine rooms, heating centers, etc., and run from heat sources to the thermal entrances of buildings. During the laying of thermal pipelines, the thermal pipelines need to be hoisted. During the hoisting of the thermal pipelines, on the one hand, the hoisting rope cannot pass through the inner wall of the thermal pipeline, which may damage the thermal insulation coating inside the thermal pipeline; on the other hand, the hoisting rope cannot be directly fixed on the polyethylene outer layer, which may damage the polyethylene outer insulation layer.

[0003] At present, in the lifting of thermal pipelines, the two ends of the lifting rope are usually fixed to the exposed steel pipe structure layers on both sides of the thermal pipeline, and then the thermal pipeline is lifted.

[0004] In the above-mentioned method for hoisting the thermal pipe, the rope may be easily lost during the actual hoisting process, which may cause the thermal pipe to fall from a high altitude or hit the ground and be damaged, greatly increasing the danger during the hoisting process. Utility Model Content

[0005] In order to effectively avoid the situation of rope coming off during the hoisting process and improve the safety during the hoisting process, the present application provides a hoisting device for a thermal pipeline.

[0006] The present application provides a thermal pipeline hoisting device, which adopts the following technical solution:

[0007] A lifting device for a thermal pipeline comprises lifting buckles sleeved on the steel pipe structure layer at both ends of the thermal pipeline, each of the lifting buckles is sleeved with a first sling, each of the lifting buckles is provided with a limiting structure, the limiting structure is used to limit the first sling to be limited on the lifting buckle, buckle ears are provided on both sides of each lifting buckle, a connecting structure is provided between the corresponding buckle ears on the two lifting buckles, the connecting structure is used to clamp the two lifting buckles at the two ends of the thermal pipeline, and the tops of the two first slings are connected by a second sling.

[0008] By adopting the above technical solution, two relatively arranged lifting buckles are used to prevent the lifting belt from directly contacting the surface of the thermal pipe. At the same time, the setting of the limiting structure effectively prevents the first lifting belt from falling off the lifting buckle. The lifting buckles are tightly connected together with the help of the connecting structure, which further improves the stability of the lifting device, effectively avoids the situation of rope coming off during the lifting process, and improves the safety during the lifting process.

[0009] Preferably, each of the limiting structures includes a sling groove opened on the corresponding lifting buckle, and the first sling passes through the sling groove and is sleeved on the lifting buckle.

[0010] By adopting the above technical solution, the first sling is passed through the sling groove in sequence, so that the first sling is limited in the sling groove. At the same time, a side wall of the sling groove forms a constraint on the first sling, further preventing the first sling from falling off the lifting buckle, and further improving the overall safety of the lifting device.

[0011] Preferably, the number of sling grooves on each of the lifting buckles is four and a circular array is provided on the lifting buckle;

[0012] Each of the sling grooves is an arc-shaped groove.

[0013] By adopting the above technical solution, the four lifting grooves further increase the limitation of the first lifting belt. At the same time, the arc-shaped groove structure is adopted, so that the first lifting belt fits more closely with the lifting groove, and effectively improves the convenience of installing the first lifting belt in the lifting groove.

[0014] Preferably, each of the connecting structures includes a first buckle connecting belt and a second buckle connecting belt connected between the corresponding two buckle ears, and a fastener is provided between the first buckle connecting belt and the second buckle connecting belt, and the fastener is used to form a strong constraint between the first buckle connecting belt and the second buckle connecting belt.

[0015] By adopting the above technical solution, the first buckle connecting belt, the second buckle connecting belt and the fastener cooperate with each other, effectively improving the tightness between the two lifting buckles, so that the two lifting buckles can be better limited at the two ends of the thermal pipeline, further improving the stability of the device.

[0016] Preferably, the fastener includes a third buckle connecting belt connected between the first buckle connecting belt and the second buckle connecting belt, one end of the third buckle connecting belt is fastened to the first buckle connecting belt by a fastening bolt, and the other end of the third buckle connecting belt is also fastened to the second buckle connecting belt by a fastening bolt.

[0017] By adopting the above technical solution, the fastening bolts realize the fastening connection between the first buckle connecting belt and the second buckle connecting belt, further improving the overall stability of the device. At the same time, this part can help the thermal pipeline reduce the deformation generated in the middle part.

[0018] Preferably, the second sling is bent in the middle, and a triangular structure is formed between the second sling and the thermal pipe. A limit piece is horizontally arranged on the top of the second sling, and the limit piece is used to limit the movement range of the hook on the second sling.

[0019] By adopting the above technical solution, the second sling bent in a triangle can be more convenient for the hook to hoist the second sling. At the same time, a limiting piece is added to the top of the second sling, which can effectively ensure that the movement range of the hook is limited when it is located at the top of the second sling for hoisting, thereby effectively ensuring that the center of the thermal pipe will not be excessively offset.

[0020] Preferably, the limiting member comprises a fourth buckle connecting belt and a fifth buckle connecting belt connected between two side surfaces of the second sling, and a sixth buckle connecting belt is arranged between the fourth buckle connecting belt and the fifth buckle connecting belt;

[0021] One end of the fourth buckle connecting belt away from the second sling is fixedly connected to one end of the sixth buckle connecting belt by a fastening bolt, and the other end of the sixth buckle connecting belt is fixedly connected to one end of the fifth buckle connecting belt away from the second sling by a fastening bolt.

[0022] By adopting the above technical solution, the fourth buckle connecting belt, the fifth buckle connecting belt and the sixth buckle connecting belt cooperate with each other to form a limiting area for the hook at the top of the second sling, and at the same time, fastening bolts are used for fixed connection to further improve the overall stability of the device.

[0023] Preferably, a plurality of U-shaped grooves are provided circumferentially on the inner wall of the lifting buckle, and the U-shaped grooves are engaged with the outer surfaces of the pipe structure layers at both ends of the thermal pipe.

[0024] By adopting the above technical solution, it is convenient to clamp the lifting buckle to the two ends of the thermal pipeline, effectively avoiding the relative rotation of the lifting buckle on the thermal pipeline, and further improving the stability of the device.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. By using two relatively arranged lifting buckles, the lifting belt is prevented from directly contacting the surface of the thermal pipe. At the same time, the setting of the limiting structure effectively prevents the first lifting belt from falling off the lifting buckle. The lifting buckles are tightly connected together by means of the connecting structure, which further improves the stability of the lifting device, effectively avoids the situation of rope falling during the lifting process, and improves the safety during the lifting process;

[0027] 2. By adding a limiter, the movement range of the hook can be effectively limited when the hook is located at the top of the second lifting belt for lifting. At the same time, it can prevent the weight loss of the pipeline due to the instability of the pipeline center during the pipeline lifting process, and ensure that the center of the thermal pipeline will not be excessively offset;

[0028] 3. The fastening bolts are used comprehensively to achieve a fastening connection between the first buckle connecting belt and the second buckle connecting belt, thereby further improving the overall stability of the device.
