[0019] Embodiment 1:

[0020] like Figures 1 to 3 As shown, this embodiment proposes: a temperature-raising and viscosity-reducing hydraulic oil cylinder, comprising a cylinder body 1 and an oil hole 2 arranged outside the cylinder body 1 (the cylinder body 1 is the hydraulic oil cylinder body, and the oil hole 2 is located at the front end of the cylinder body 1);

[0021] The cylinder body 1 is surrounded by two sets of relatively fitted heating ring clamps 3 (as shown in the figure, the two sets of heating ring clamps 3 are symmetrically distributed at the left and right ends of the cylinder body 1 to clamp the cylinder body 1);

[0022] The heating ring clamp 3 is provided with a notch 4 (such as Figure 1As shown, grooves are provided on the heating ring clamp 3 at the left and right ends of the oil hole 2 to ensure that the oil hole 2 will not be blocked when the heating ring clamp 3 is attached to the cylinder body 1, and the structure is reasonable) (according to the above, recesses 4 are provided at necessary oil holes 2, and the remaining heating ring clamps 3 covering the cylinder body 1 are attached and covered, so as to increase the heating area and enhance the heating efficiency).

[0023] The two groups of heating ring clamps 3 are detachably fixed by the fastening assembly 5 (the two groups of heating ring clamps 3 attached to the outside of the cylinder body 1 are directly fixed to the attached position by the fastening assembly 5, without the need for external force components for support and displacement adjustment, and the structure is simple and easy to use);

[0024] The two groups of heating ring clamps 3 completely fit the outer side of the cylinder body 1 (that is, when the surrounding ring surface of the cylinder body 1 is cylindrical, the cavity formed between the two groups of heating ring clamps 3 is cylindrical and just fits the surface of the cylinder body 1, thereby increasing the fitting area and the heating efficiency);

[0025] In order to implement the above-mentioned fastening assembly 5, it is proposed that Figures 1-2 As shown, the specific structure and composition of the fastening assembly 5 can be as follows: the fastening assembly 5 includes two sets of fixing plates 51 (such as Figure 2 As shown, the fixing plates 51 are symmetrically arranged at the front and rear ends of the heating ring clamp 3, and the heating ring clamps 3 arranged on the left and right are arranged opposite to each other, that is, the fixing plates 51 are arranged opposite to each other);

[0026] The two sets of fixing plates 51 are simultaneously penetrated by at least one set of fixing holes 52 (such as Figures 1-2 As shown, the fixing holes 52 penetrate both ends of the left and right sets of fixing plates 51, and two sets of fixing holes 52 are provided);

[0027] The bolt 53 is passed through one end of the fixing hole 52 to the other end, and the bolt 53 is partially exposed and threadedly connected to the nut 54 (such as Figures 1-2 As shown, the bolt 53 is inserted from right to left into the fixing hole 52, so that the two sets of fixing plates 51 and the heating ring clamp 3 can be connected as one, and then the nut 54 is used to strengthen and stabilize the left end. The structure is simple and easy to disassemble and assemble.

[0028] Furthermore, the bolt 53 is externally threadedly connected to the fixing hole 52 , that is, the bolt 53 is firmly connected to the fixing hole 52 in advance, which can improve the connection strength of the assembly.

[0029] In order to realize the implementation and use of the above-mentioned heating ring clamp 3, it is proposed that Figure 3 As shown, the specific structure and composition of the heating ring clamp 3 can be as follows: the heating ring clamp 3 includes a heating clamp 31, the outer side of the heating clamp 31 is fixedly connected to the fixing plate 51, the heating clamp 31 is attached to the outer side of the cylinder body 1 (as shown in the figure), and the heating clamp 31 is a heating plate;

[0030] The heating clamping plate 31 is provided with an electrical connection line 32 and also includes a controller (not shown) connected to the electrical connection line 32, and the controller is connected to an external power source.

[0031] Embodiment 2:

[0032] like Figure 3 As shown, the difference between it and embodiment 1 is that: the heating ring clamp 3 also includes a soft insulation layer 33 fixedly attached to the outer side of the heating clamp 31 or a soft insulation layer 33 fixedly attached to the outer side of the heating clamp 31 and the fixing plate 51 (that is, the soft insulation layer 33 can be fixed only on the outer side of the heating clamp 31 by bonding or the like, or fixed on the outer side of the heating clamp 31 and the fixing plate 51 at the same time, and the latter has a better insulation effect), (the insulation layer 9 is a material with low thermal conductivity, such as polyurethane foam, etc., to improve heat loss and increase thermal insulation).

[0033] A soft heat-conducting layer 34 that is in contact with the soft heat-insulating layer 33 is fixedly provided on the side of the heating clamping plate 31 that is in contact with the outside of the cylinder body 1 (as shown in the figure, the side of the heating clamping plate 31 that faces the cylinder body 1 is fixedly provided by bonding or the like);

[0034] The soft heat-conducting layer 34 and the soft heat-insulating layer 33 are attached to the outer side of the cylinder body 1, and the soft effect provided can better perform compression and improve the stability of assembly (the soft heat-conducting layer 34 can be heat-conducting silicone, etc.).

[0035] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0036] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0037] In addition, it should be understood that although this specification is described in accordance with the implementation modes, not every implementation mode includes only one independent technical solution, and this description method of the specification is only for the purpose of clarity.

[0038] For the sake of clarity, those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
