Description

Technical Field

[0001] This application relates to the field of suspension device technology, and in particular to a device for suspending resistors. Background Technology

[0002] Suspension mounting is a common installation method for resistors, where they are typically mounted in a location using a suspension device or beam. Currently, resistor suspension devices are mostly beam structures, using two or more rectangular tubes or bent parts connected to the resistor housing to suspend the entire resistor.

[0003] Patent document CN102479590A discloses a diagonal bracing resistor suspension device, comprising a main beam, a pad, and a diagonal support assembly. The main beam is located at the top of the device, and the diagonal support assembly is located at the bottom of the main beam. The appropriate angle can be selected before installation. The pad is placed between the diagonal support assembly and the main beam. Compared with existing technologies, this invention utilizes the diagonal support assembly to enhance the rigidity of the beam and the overall structural strength. The suspension beam is connected to the front and rear side plates of the resistor housing via the diagonal support, thereby distributing part of the load to the resistor housing and reducing the load on the beam. The diagonal bracing utilizes the principle of triangular structural stability to increase the rigidity of the resistor suspension device, thereby increasing the resistor's low-order natural frequencies. This allows the resistor to avoid or exceed the low-order natural frequencies of the equipment or machine body on which the resistor is installed, greatly reducing the possibility of resonance.

[0004] However, the aforementioned patent documents are not convenient for quick disassembly and maintenance of resistors during use, especially when the resistors are located at high positions, which reduces maintenance efficiency. Therefore, we propose a device for suspending resistors to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing suspension devices, which make it inconvenient to quickly disassemble and maintain resistors during use, especially when the resistors are located at high positions, thus reducing maintenance efficiency. Therefore, this invention proposes a device for suspending resistors.

[0006] The device for suspending resistors provided in this application adopts the following technical solution:

[0007] An apparatus for suspending a resistor, comprising:

[0008] beam;

[0009] There are two first slides, both of which are opened at the bottom of the crossbeam;

[0010] There are two first connecting rods, and the two first connecting rods are slidably installed in the two first sliding grooves respectively.

[0011] The second connecting rod is provided in two parts. The top of each of the two second connecting rods is provided with a second sliding groove. The inner walls of the two second sliding grooves are slidably connected to the outer sides of the two first connecting rods respectively.

[0012] The adjustment mechanism is mounted on the two second connecting rods.

[0013] Furthermore, supports are fixedly installed on one side of each of the two second connecting rods, and the same resistor body is placed on top of the two supports. A motor is fixedly installed on one side of the crossbeam.

[0014] Furthermore, guide grooves are provided on one side of both supports, and the same guide post is slidably installed in the two guide grooves. The guide post is used to ensure that the two second connecting rods move synchronously.

[0015] Furthermore, the adjustment mechanism includes two locking rods, each with a sliding hole on one of the two supports. The two locking rods are slidably installed in the two sliding holes respectively. Each of the two first connecting rods has a slot on one side, and the two locking rods are engaged with the two slots respectively. When the locking rods are engaged with the slots, the locking rods can position the first connecting rods.

[0016] Furthermore, a pull rod is fixedly installed at one end of each of the two levers, and a spring is fitted on the outer side of each lever. The two ends of the spring are fixedly connected to the outer side of the pull rod and the outer side of the support, respectively.

[0017] Furthermore, a limiting groove is provided on one side inner wall of each of the two second sliding grooves, and a limiting block is slidably installed in each of the two limiting grooves. The two limiting blocks are respectively fixedly connected to the outer side of the two first connecting rods.

[0018] Furthermore, a mounting hole is provided on one side of the crossbeam, which communicates with two first sliding grooves. A bidirectional lead screw is rotatably installed in the mounting hole, and the bidirectional lead screw is threadedly connected to two first connecting rods. One end of the bidirectional lead screw is fixedly connected to the output shaft of the motor. When the motor is turned on, the bidirectional lead screw drives the two first connecting rods to move horizontally.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. When the motor is turned on, the motor drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the two first connecting rods to move closer to each other. The two first connecting rods drive the two second connecting rods to move closer to each other. The two second connecting rods can position or release the resistor body, thus facilitating disassembly and maintenance.

[0021] 2. When the two pull rods are pulled closer together, the two pull rods will cause the two locking rods to move closer together, and the two locking rods will separate from the two locking slots. This allows the two second connecting rods to move vertically downwards, thereby adjusting the height of the resistor body and avoiding the difficulty of disassembling and maintaining the resistor body when it is installed at a high position.

[0022] This invention facilitates quick disassembly and maintenance of resistors during use, especially when the resistor is located at a high position, effectively improving maintenance efficiency. It has a simple structure and is easy to use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] Reference Figures 1-4 An apparatus for suspending a resistor, comprising:

[0031] Crossbeam 1;

[0032] There are two first slide grooves 11, and both first slide grooves 11 are opened at the bottom of the crossbeam 1.

[0033] There are two first connecting rods 6, and the two first connecting rods 6 are slidably installed in the two first sliding grooves 11 respectively.

[0034] There are two second connecting rods 3. The top of each of the two second connecting rods 3 is provided with a second sliding groove 5. The inner walls of the two second sliding grooves 5 are slidably connected to the outer sides of the two first connecting rods 6 respectively.

[0035] The adjustment mechanism is mounted on the two second connecting rods 3.

[0036] Reference Figures 2-4 Each of the two second connecting rods 3 has a support 4 fixedly installed on one side. A resistor body 2 is placed on the top of each support 4. A motor 9 is fixedly installed on one side of the crossbeam 1. Each of the two supports 4 has a guide groove 12, and a guide post 13 is slidably installed within each guide groove 12. The guide post 13 ensures the synchronous movement of the two second connecting rods 3. The adjustment mechanism includes two locking rods 15. Each of the two supports 4 has a sliding hole 14, and the two locking rods 15 are slidably installed within the two sliding holes 14. Each of the two first connecting rods 6 has a slot 7 on one side, and the two locking rods 15 are engaged with the two slots 7 respectively. When the locking rod 15 is engaged with the slot 7, the locking rod 15 can position the first connecting rod 6. A pull rod 16 is fixedly installed at one end of the clamp rod 15. Springs 17 are sleeved on the outer sides of both clamp rods 15. The two ends of the springs 17 are fixedly connected to the outer side of the pull rod 16 and the outer side of the support 4, respectively. Limit grooves are opened on one side inner wall of both second slide grooves. Limit blocks 8 are slidably installed in both limit grooves. The two limit blocks 8 are fixedly connected to the outer side of the two first connecting rods 6, respectively. An installation hole is opened on one side of the crossbeam 1. The installation hole communicates with the two first slide grooves 11. A bidirectional screw 10 is rotatably installed in the installation hole. The bidirectional screw 10 is threadedly connected to the two first connecting rods 6. One end of the bidirectional screw 10 is fixedly connected to the output shaft of the motor 9. When the motor 9 is turned on, the bidirectional screw 10 drives the two first connecting rods 6 to move horizontally.

[0037] The implementation principle of the device for suspending a resistor according to an embodiment of this application is as follows: In use, by installing the crossbeam 1 at the designated installation position, the resistor body 2 is placed on top of the two supports 4. The motor 9 is turned on, and the motor 9 drives the bidirectional lead screw 10 to rotate. The bidirectional lead screw 10 drives the two first connecting rods 6 to move closer to each other. The two first connecting rods 6 respectively drive the two second connecting rods 3 to move closer to each other. The two second connecting rods 3 respectively drive the two supports 4 to move closer to each other. Thus, the two second connecting rods 3 can position the resistor body 2. When disassembly is required, the motor 9 can be turned on to reverse. At the same time, by pulling the two pull rods 16 closer to each other, the two pull rods 16 respectively drive the two locking rods 15 closer to each other. The two locking rods 15 are separated from the two locking slots 7 respectively, thus releasing the limitation on the two second connecting rods 3. Then, by pulling the two second connecting rods 3 vertically, the height of the resistor body 2 can be adjusted, avoiding the difficulty of disassembling and maintaining the resistor body 2 when it is installed at a high position.

[0038] Example 2

[0039] The difference between this embodiment and embodiment one is that anti-slip pads are fixedly installed on one side of both second connecting rods 3. The two anti-slip pads cooperate with the resistor body 2. By setting the two anti-slip pads, the stability of the resistor body 2 suspension can be effectively guaranteed.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
