Description

Technical Field

[0001] The utility model relates to the technical field of heating belts, in particular to a fixing device of the heating belt. Background Art

[0002] Trace Heating is a heating system used to heat pipes, containers, valves and other equipment. It usually consists of heating cables (also called trace heating cables). These cables are installed on the surface or inside the equipment that needs to be heated, and provide heating by converting electrical energy into thermal energy. Usually, the trace heating cable is bonded to the surface of the equipment by glue or other means, but over time, the glue is prone to failure, causing the trace heating cable to detach from the equipment, so additional devices are needed to fix the trace heating cable.

[0003] A Chinese patent with publication number CN220337806U discloses a medium-temperature self-limiting electric heating belt fixing device, including a fixing body and a bonding surface. The bonding surface is bonded to the outer surface of the equipment by glue, and the two ends of the heating belt are connected to the bonding surface. The fixing body is fixed to the bonding surface by a threaded rod, and the connection between the heating belt and the bonding surface is squeezed to make the heating belt closer to the surface of the equipment, thereby making the heating belt less likely to fall off.

[0004] However, in the above technology, when the threaded rod rotates into the internal threaded ring on the fixed body, the fixed body will move in the direction close to the bonding surface, thereby achieving compression of the heating belt. However, since the force is mutual, the bonding surface will also be subjected to the force close to the fixed body, that is, the force away from the surface of the equipment. Therefore, when tightening the threaded rod, the connection stability between the bonding surface and the equipment may be reduced due to the threaded rod, which may easily cause the bonding surface to fall off the equipment, thereby causing the fixing device to fail.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-7 , the utility model is described in further detail.

[0029] A heating tape fixing device, referring to Figure 1-7 , including a fixing ring 3, a first connecting block 4, a second connecting block 5 and a connecting piece 6.

[0030] The fixing device in this embodiment is suitable for pipeline-type equipment 1. Therefore, the fixing ring 3 is coaxially sleeved on the outer peripheral wall of the equipment 1. At the same time, the heating belt 2 is bonded to the outer peripheral wall of the equipment 1. The heating belt 2 in this embodiment is arranged around the axis of the equipment 1. The fixing ring 3 is located on the outside of the heating belt 2 and is coaxially arranged. A clearance groove 31 for placing the heating belt 2 is opened on the fixing ring 3 to prevent the fixing ring 3 from exerting excessive pressure on the heating belt 2, which may cause damage to the heating belt 2.

[0031] It should be noted that the heating belt 2 in this embodiment is in the shape of a long strip, which is arranged around the axis of the device 1 and thus forms a ring. At the same time, when the heating belt 2 is wound around the device 1, the two ends of the heating belt 2 abut against each other.

[0032] The fixing ring 3 in this embodiment has a certain elasticity, and a fracture is set somewhere on the fixing ring 3. The first connecting block 4 is fixedly connected to one of the fractures, and the second connecting block 5 is fixedly connected to the other fracture. When the fixing device is installed on the equipment 1, the fixing ring 3 is sleeved on the equipment 1, and the heating belt 2 is located in the make way groove 31 of the fixing ring 3, and the first connecting block 4 and the second connecting block 5 are opposite to the connection between the two ends of the heating belt 2. The first connecting block 4 is provided with a connecting piece 6, and the connecting piece 6 can make the first connecting block 4 and the second connecting block 5 move in the direction of approaching or moving away from each other, so as to achieve the purpose of connecting the first connecting block 4 and the second connecting block 5.

[0033] When the first connecting block 4 and the second connecting block 5 move in a direction approaching each other, the first connecting block 4 and the second connecting block 5 will drive the fixing ring 3 to contract, so that the fixing ring 3 can be pressed against the outer peripheral wall of the device 1. At the same time, the first connecting block 4 and the second connecting block 5 will also move in a direction approaching the device 1 until they are pressed against the outer peripheral wall of the device 1. Since the first connecting block 4 and the second connecting block 5 are directly opposite to the connection at both ends of the heating belt 2, the first connecting block 4 and the second connecting block 5 can press the connection at both ends of the heating belt 2 against the outer peripheral wall of the device 1, thereby making it difficult for the heating belt 2 to fall off the device 1. At the same time, the fixing ring 3 is mechanically locked by the connecting piece 6, so that the fixing ring 3 can be relatively stably tightened on the device 1, thereby making the connection between the fixing ring 3 and the device 1 in a relatively stable state, thereby improving the connection stability between the heating belt 2 and the device 1.

[0034] In addition, a clearance groove 31 is provided on the fixing ring 3, so the fixing ring 3 will not squeeze the heating belt 2, thereby reducing the probability of damage to the heating belt 2 by the fixing device, and when the heating belt 2 is located in the clearance groove 31, the fixing ring 3 can block the two sides of the heating belt 2 to a certain extent, thereby avoiding wind and sand from penetrating into the connection gap between the heating belt 2 and the equipment 1 as much as possible, causing the glue to fail, thereby further improving the connection stability between the heating belt 2 and the equipment 1.

[0035] In order to further reduce the probability of damage to the heating belt 2 by the fixing ring 3, a groove 54 is provided on the end surface of the first connecting block 4 and the second connecting block 5 facing the heating belt 2. The cross-section of the groove 54 is set to be semicircular, which is relatively consistent with the shape of the cross-section of the heating belt 2. It can increase the contact area between the heating belt 2 and the first connecting block 4 and the second connecting block 5, thereby reducing the pressure of the first connecting block 4 and the second connecting block 5 on the heating belt 2.

[0036] At the same time, a rubber layer (not shown in the figure) is arranged on the groove wall of the groove 54, which further reduces the probability of the first connecting block 4 and the second connecting block 5 damaging the heating belt 2, thereby increasing the service life of the heating belt 2.

[0037] The connecting member 6 includes a rotating rod 61 and a limiting block 62 .

[0038] The rotating rod 61 is passed through the upper end surface of the first connecting block 4 to the lower end surface of the first connecting block 4, and the rotating rod 61 is rotatably connected to the first connecting block 4. The limit block 62 is fixedly installed on the rotating peripheral wall, and the limit block 62 is located at the lower end surface of the first connecting block 4. The upper end surface of the second connecting block 5 is provided with a slide groove 51 for the rotating rod 61 to slide into, and a through groove 52 for the limit block 62 to slide into. The slide groove 51 and the through groove 52 are connected. The interior of the second connecting block 5 is provided with a limit groove 53, and the limit groove 53 is simultaneously connected with the slide groove 51 and the through groove 52.

[0039] When it is necessary to connect the first connecting block 4 and the second connecting block 5, the rotating rod 61 is inserted into the sliding groove 51, and at the same time, the limit block 62 is driven to slide and insert into the through groove 52 until the first connecting block 4 and the second connecting block 5 are abutted, and the limit block 62 also reaches the lowest space in the through groove 52, and then the rotating rod 61 is rotated to make the limit block 62 slide into the limit groove 53, and the limit block 62 abuts against the groove wall of the limit groove 53, and the rotating rod 61 and the limit block 62 cannot slide along the original route, thereby realizing the connection between the first connecting block 4 and the second connecting block 5.

[0040] In order to facilitate the rotation of the rotating rod 61, a rotating handle 63 is further provided on the upper end surface of the rotating rod 61 to facilitate the operation of the staff.

[0041] In this embodiment, two connecting members 6 are provided, and two corresponding sliding grooves 51 , through grooves 52 , and limiting grooves 53 are provided to enhance the connection stability between the first connecting block 4 and the second connecting block 5 .

[0042] Secondly, the clearance groove 31 in this embodiment divides the fixing ring 3 into a first half ring 32 and a second half ring 33. The two ends of the first half ring 32 and the second half ring 33 are respectively fixedly connected to the first connecting block 4 and the second connecting block 5. An adjusting member 7 capable of adjusting the distance between the first half ring 32 and the second half ring 33 is provided between the first half ring 32 and the second half ring 33.

[0043] The adjusting member 7 includes a first adjusting block 71, a second adjusting block 72 and a threaded rod 73. The first adjusting block 71 and the second adjusting block 72 are arranged relatively to each other in the horizontal direction. The first adjusting block 71 is fixedly mounted on the first half ring 32, and the second adjusting block 72 is fixedly mounted on the second half ring 33. The first adjusting block 71 is provided with a first threaded hole 711 for the threaded rod 73 to pass through, and the second adjusting block 72 is provided with a second threaded hole 721 for the threaded rod 73 to be inserted into. The first threaded hole 711 is communicated with the second threaded hole 721.

[0044] When the fixing ring 3 is sleeved on the device 1 and the heating belt 2 is located between the first half ring 32 and the second half ring 33, the first adjusting block 71 and the second adjusting block 72 are moved in a direction approaching each other by rotating the threaded rod 73 in the forward direction, thereby driving the first half ring 32 and the second half ring 33 to move in a direction approaching each other until the first half ring 32 and the second half ring 33 block the gaps on both sides of the heating belt 2, thereby avoiding as much as possible that sand and other debris enter the connection gap between the heating belt 2 and the device 1, resulting in the failure of the glue on the heating belt 2, thereby further reducing the probability of the heating belt 2 falling off the device 1 and improving the connection stability between the heating belt 2 and the device 1.

[0045] The embodiments of this specific implementation are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
