Description

Technical Field

[0001] This utility model relates to the field of circuit maintenance technology, and in particular to a fault inspection and maintenance device for fire alarm circuits. Background Technology

[0002] As a connecting tool for transmitting and transmitting electrical power, wires are ubiquitous in today's high-tech and highly mechanized production operations. After long-term continuous use, phenomena such as overload and short circuits often occur, which require testing with a line inspection instrument. As the wiring laid in the alarm system, alarm lines also need to be inspected and maintained in fire protection maintenance work.

[0003] In line maintenance work, inspection instruments and testing clips connected to the wires are usually used for testing. For example, the utility model with announcement number CN219978357U discloses a line inspection instrument, which includes an instrument body. The instrument body is provided with a testing structure, which includes a testing component and a handle component. The testing component includes a lifting component and a testing assembly, and the testing assembly is provided with a control component and a limiting component. This utility model, through the setting of the lifting component, the testing assembly, and the handle component, can control the height of the testing assembly and the opening and closing of the arc plate, thereby inspecting wires at different heights. Then, by moving the handle, the arc plate can be moved along the wire to check it, which is quite convenient to use.

[0004] However, when the inspection instrument and testing clamp in the above application are used to inspect high-altitude lines, the operator needs to hold the raised testing clamp while starting the motor to hold the line to be inspected. This makes it difficult for the operator to hold the entire device stably and hold the line clamp when inspecting high-altitude lines, and it is easy to cause shaking, thus affecting the inspection efficiency. Therefore, a fire alarm line fault inspection and maintenance device is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-4 As shown, the present invention proposes a fire alarm circuit fault inspection and maintenance equipment, which includes a base plate 1 and a detector 3 installed on the base plate 1. A set of support plates 4 are fixedly connected to the base plate 1.

[0028] The end of the support plate 4 is provided with a detection element 5 for line fault repair.

[0029] In this invention, the detection component 5 located on the support plate 4 facilitates the operator's testing of the stability of the line at a high position, thereby improving the convenience of the testing.

[0030] In an optional embodiment, the detection element 5 includes a support rod 51 rotatably connected to the upper end of the support plate 4. A placement cylinder 52 is fixedly connected to the end of the support rod 51 away from the support plate 4. A multi-stage electric push rod 53 is fixedly installed on the inner side of the placement cylinder 52. A telescopic rod 54 is inserted into the inner side of the placement cylinder 52. A support block 55 is fixedly connected to the upper end of the telescopic rod 54. A gripping rod 58 is rotatably connected to the lower surface of the support block 55. A connecting ring 59 is threadedly connected to the upper end of the gripping rod 58. A set of detection clips 56 is hinged to the upper surface of the support block 55. A hinge rod 57 with one end hinged to the connecting ring 59 is hinged to the outer side of the detection clips 56.

[0031] A pull rod 510 is slidably connected to the outside of the placement cylinder 52, with one end passing through and extending into the inside of the telescopic rod 54. A spring 511 is fixedly connected between the pull rod 510 and the placement cylinder 52.

[0032] In this embodiment, when the support block 55 is raised by the multi-stage electric push rod 53, the operator only needs to hold the handle 58 and adjust the position of the detection clamp 56 by using the support rod 51 and the moving wheels 2 on the base plate 1. The operator can then rotate the handle 58 to drive the detection clamp 56 to stably clamp the line to be tested, thereby improving the stability and convenience of testing lines at high heights. For lines at lower heights, the telescopic rod 54 can be removed by pulling the pull rod 510. The operator can then hold the handle 58 and the telescopic rod 54 to perform the test, further improving the convenience of the test and thus increasing the testing efficiency.

[0033] It should be noted that the telescopic rod 54 is composed of a connecting rod 541, a sleeve 542, and a sleeve rod 543. The sleeve 542 is slidably connected to the outside of the connecting rod 541, and the sleeve rod 543 is slidably connected to the outside of the sleeve 542. The upper end of the connecting rod 541 is fixedly connected to the support block 55, and its lower end abuts against the output end of the multi-stage electric push rod 53, so that the telescopic rod 54 composed of the connecting rod 541, the sleeve 542, and the sleeve rod 543 can slide and extend and adjust to each other.

[0034] The connecting rod 541 and the outer side of the sleeve 542 are both fixedly connected to the first slider. The inner walls of the sleeve 543 and the sleeve 542 are both provided with the first sliding groove for the slider to slide, so that the connecting rod 541, the sleeve 542 and the sleeve 543 will not separate from each other during the sliding process.

[0035] In addition, the end of the pull rod 510 away from the placement cylinder 52 is T-shaped, and a pull ring is rotatably connected to the T-end. The spring 511 is fixedly connected between the T-end of the pull rod 510 and the placement cylinder 52. A support groove adapted to the pull rod 510 is opened on the outer side of the lower end of the sleeve rod 543. The sleeve rod 543 inserted into the placement cylinder 52 is supported and limited by the pull rod 510 extending into the support groove.

[0036] Secondly, the handle 58 consists of a vertical rod and a connecting cylinder. The vertical rod is rotatably connected to the support block 55, and the connecting cylinder is slidably connected to the outside of the vertical rod. A second slider with one end extending into the inside of the connecting cylinder is fixedly connected to the outside of the vertical rod. The inner wall of the connecting cylinder is provided with a second sliding groove for the second slider to slide, so that the connecting cylinder can slide on the outside of the vertical rod while also driving the vertical rod to rotate together.

[0037] Then, an external thread is provided on the outer surface of the upper end of the vertical rod, and an internal thread is provided on the inner circumferential wall of the connecting ring 59. The threads and external threads cooperate with each other, so that the rotating vertical rod can drive the connecting ring 59 to move and adjust along the vertical and horizontal plane on the outer side of its upper end.

[0038] In the above embodiments, a control switch electrically connected to the multi-stage electric push rod 53 is provided on the outer side of the lower end of the placement cylinder 52. The detector 3 is electrically connected to the detection clamp 56. The power supply method of the multi-stage electric push rod 53 is the same as that of the detector 3. The control circuit of the control switch can be implemented by simple programming by those skilled in the art and is common knowledge in the art. The detection method of the detection clamp 56 has been clearly disclosed in the prior art and is also common knowledge in the art. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail in this utility model.

[0039] The working principle in the above embodiments is as follows:

[0040] Since the support rod 51 can support the placement cylinder 52 to rotate and adjust on the support plate 4, the telescopic rod 54 inserted into the placement cylinder 52 can rotate together with the placement cylinder 52. When inspecting the high-altitude line, the operator only needs to hold the connecting cylinder on the grip rod 58, and then start the multi-stage electric push rod 53 to push the connecting rod 541 and sleeve 542 on the telescopic rod 54 to extend and retract, so as to drive the support block 55 and the detection clamp 56 to rise. After adjusting the position of the detection clamp 56 by holding the connecting cylinder and the moving wheel 2 on the base plate 1, the vertical rod on the grip rod 58 can be rotated by rotating the connecting cylinder, so as to drive the connecting ring 59 to move towards the side closer to the support block 55. Then, the detection clamp 56 is pushed by the hinge rod 57 to clamp the high-altitude line to be inspected, and the inspection can be carried out. During the inspection process, the operator does not need to stably support the detection clamp 56 to improve the stability and convenience of the detection clamp 56 clamping the line.

[0041] For testing lines with low heights, pull the lever 510 to remove the telescopic rod 54 inserted into the placement cylinder 52, and hold the connecting cylinder on the handle 58 and the vertical rod 541 on the telescopic rod 54 to move the test clamp 56 to the line for clamping and testing.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
