[0003] The signal cable reel is a part to ensure the signal transmission between the electrical room and the driver's cab of the cable machine, and the torque motor of the communication cable enables the normal operation of the signal transmission between the electrical room and the driver's cab of the cable machine. The signal cable full-pass is a cable retracting and releasing device for rail-mounted electrical equipment.

[0004] However, there are some problems in the prior art: in a low-temperature environment in winter, the ambient temperature is lower than the rated working temperature of the torque speed regulator, resulting in an unstable working state of the torque speed regulator. When the voltage of the torque speed regulator fluctuates, the torque feedback to the torque motor is not timely, and the motor speed cannot reach the required value, which may cause damage to the communication cable. Therefore, to ensure the normal operation of the torque motor of the communication cable of the cable machine in a low-temperature environment in winter, we propose a torque motor heating device for a signal cable reel which is convenient for disassembly and assembly.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings of 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.

[0026] This embodiment provides a heating device for the torque motor of the signal cable reel that is convenient for disassembly and assembly. As Figure 1 shown, the heating device for the torque motor of the signal cable reel that is convenient for disassembly and assembly includes a housing 1 of the torque speed regulator. The heating tape 2 is installed inside the housing 1 of the torque speed regulator through a plurality of groups of fixing components; each group of fixing components includes a concave-shaped fixing part 3 and an inner wall fixing plate 4. As Figure 2 shown, the heating tape 2 is spirally wound around the inner wall of the housing 1 of the torque speed regulator through a plurality of groups of fixing components; at the same time, as Figure 1 and Figure 2As shown, the tail end of the heating tape 2 penetrates through the housing 1 of the torque speed governor and extends to the outside, and a plug 5 for connecting to the power supply is provided at the tail end of the heating tape 2. The heating tape 2 is a commercially available finished product and is commonly used for heating and heat preservation of tanks, pipes, troughs and other containers of various industrial equipment, such as Figure 3 As shown, a power cord 6 is connected inside the heating tape 2, and the power cord 6 can be electrically connected to the commercially available plug 5.

[0027] In a low-temperature environment in winter, the heating tape 2 is connected to the power supply through the plug 5. The helically wound heating tape 2 generates heat inside the housing 1 of the torque speed governor, so that the ambient temperature inside the housing 1 of the torque speed governor can be ensured not to be lower than the rated operating temperature of the torque speed governor, ensuring the stable working state of the torque speed governor, and at the same time, it can also play a moisture-proof role.

[0028] Furthermore, for the convenience of understanding how the heating tape 2 is helically wound on the inner wall of the housing 1 of the torque speed governor through several groups of fixing components, the specific structures of the concave-shaped fixing member 3 and the inner wall fixing plate 4 are given in this embodiment:

[0029] As Figure 2 shown, the inner wall fixing plates 4 in this embodiment are arranged in a straight line at equal intervals inside the housing 1 of the torque speed governor and are matched with the positions of the fixing components; the inner wall fixing plates 4 are a pair of plate bodies parallelly installed on the inner wall of the housing 1 of the torque speed governor, and a gap for the heating tape 2 to pass through is formed between the pair of plate bodies.

[0030] As Figure 4 shown, the concave-shaped fixing members 3 of several groups of fixing components in the embodiment are arranged in a straight line at equal intervals; each concave-shaped fixing member 3 includes a connecting plate 7, and side plates 8 are integrally formed on the left and right sides of the connecting plate 7, thus forming a fixing member with an overall concave shape; the size of the inner wall fixing plate 4 is adapted to the internal size of the housing 1 of the torque speed governor, and the top of the side plate 8 can be attached to the inner wall of the housing 1 of the torque speed governor, and the inner wall fixing plate 4 is located at the concave opening of the concave-shaped fixing member 3. As Figure 4 and Figure 5 shown, a second placement groove 10 recessed inward is provided on the upper end surface of the connecting plate 7, and a first placement groove 9 recessed inward and communicating with the second placement groove 10 is provided on the inner side of the side plate 8.

[0031] In addition, considering that the heating tape 2 is helically wound on the inner wall of the housing 1 of the torque speed governor and needs to extend from one group of inner wall fixing plates 4 and concave-shaped fixing members 3 to another group of inner wall fixing plates 4 and concave-shaped fixing members 3, therefore as Figure 4 and Figure 5 shown, a wire passing groove 11 is provided at the notch of the first placement groove 9 at the upper end of the side plate 8 in this embodiment to facilitate the wiring of the heating tape 2.

[0032] Through the specific structures of the above-mentioned concave-shaped fixing member 3 and the inner wall fixing plate 4, after the heating belt 2 is installed in a rectangular shape around the inner wall of the torque speed regulator housing 1 through the first placement groove 9, the second placement groove 10, and the inner wall fixing plate 4, the notch of the first placement groove 9 extends to the next set of fixing components for extension, and is arranged in a rectangular shape. Finally, the tail end of the heating belt 2 penetrates through the torque speed regulator housing 1 and extends to the outside.

[0033] Furthermore, since there are components that can rotate the output end of the motor installed in the torque speed regulator housing 1, to prevent the heating belt 2 from detaching from the first placement groove, the second placement groove 10, and the inner wall fixing plate 4, which may affect the operation of the motor; therefore, as Figure 2 、 Figure 4 and Figure 5 shown, in this embodiment, both the concave-shaped fixing member 3 and the inner wall fixing plate 4 are provided with limiting grooves 12, and a limiting block 13 for limiting the heating belt 2 is installed through the limiting grooves 12; the limiting block 13 is inserted into the limiting groove 12 and passes through the gaps between the two plate bodies of the first placement groove 9, the second placement groove 10, and the inner wall fixing plate 4, thereby limiting the heating belt 2.

[0034] Since the limiting block 13 and the limiting groove 12 are in a plug-in connection, to prevent the limiting block 13 from completely disengaging from the limiting groove 12, therefore, as Figure 6 shown, in this embodiment, a limiting pin 14 is provided on the extraction side in the limiting groove 12, and a groove body for cooperating with the limiting pin 14 is provided on the limiting block 13. Thus, after the limiting pin 14 is pulled out, the heating belt 2 can be quickly disassembled from the placement groove, and at the same time, the limiting block 13 will not disengage from the limiting groove 12, increasing the convenience of use.

[0035] In addition, to prevent the limiting block 13 from deforming due to temperature influence after long-term use, resulting in loosening between it and the limiting groove 12 and losing the limiting effect on the heating belt 2; as Figure 2 、 Figure 6 and Figure 7 shown, in this embodiment, the concave-shaped fixing member 3 and the inner wall fixing plate 4 are provided with pins 15 for positioning the limiting block 13 at the limiting groove 12, and at the same time, the limiting block 13 is provided with jacks 16 for cooperating with the pins 15, so as to further limit the limiting block 13.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
