Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering construction, in particular to a safety control device for detecting underground pipelines. Background Technique

[0002] Municipal engineering construction generally involves excavation operations. Since various pipelines (such as national defense optical cables, communication optical cables, gas, water supply, power supply, etc.) are generally buried underground, it is inevitable to affect underground pipelines during excavation construction. For example, if the pipeline disclosure or detection is not timely or accurate, potential safety hazards are likely to occur, and even safety accidents may be triggered. Specifically as follows:

[0003] 1. Existing conventional pipeline detection equipment has a low sensitivity and has a good detection effect for pipelines buried relatively shallowly. However, when the pipeline is buried deeply (depth greater than 5m), the detection effect of conventional pipeline detection equipment is poor, and even the existing underground pipelines cannot be detected.

[0004] 2. Some pipelines have been built for a long time. At that time, the construction management and pipeline data file management were relatively extensive. Many pipeline data deviated greatly from the actual situation or even were missing. Another example is that when the pipeline operation and maintenance management personnel are replaced, they do not have a clear understanding of the existing pipelines and the disclosure is not in place.

[0005] 3. Due to insufficient disclosure and training, or affected by their own operation level, it is very difficult for excavator operators to perceive the existence of underground pipelines during the operation of the machine. Content of the Utility Model

[0006] In view of the deficiencies in the prior art, the utility model provides a safety control device for detecting underground pipelines. To achieve the above object, the utility model adopts the following technical solutions:

[0007] A safety control device for detecting underground pipelines includes an excavator and a pipeline detector. The excavator includes a fuselage, a boom, an arm and a bucket. It further includes a fixing frame, two mounting blocks, a rotating block and a control system. The fixing frame is fixed inside the arm and above the bucket. The mounting blocks are installed at both ends of the fixing frame. The rotating block is rotatably installed on the mounting blocks. The pipeline detector is hinged and installed on the rotating block and is located on both sides of the bucket respectively. The control system is installed in the cab of the fuselage. The control system is connected to the pipeline detector through a signal transmission wire and is used to receive the signal of the pipeline detector to control the shutdown of the excavator.

[0008] Furthermore, the fixing bracket includes two parallel fixing plates, a connecting column, two adjusting rods and a resisting block. The connecting column passes through the two fixing plates and is fixedly connected to the fixing plates. The adjusting rods are respectively threadedly connected to the fixing plates. The resisting block is fixed at the end of the adjusting rod. The resisting block is pressed against the small arm by the adjusting rod. A locking nut is threadedly connected to the adjusting rod.

[0009] Furthermore, the mounting blocks are slidably connected to both ends of the connecting column. A threaded rod arranged in parallel with the connecting column is rotatably connected to the fixing plate. The two ends of the threaded rod are symmetrically threaded. The mounting blocks are symmetrically threadedly connected to the threaded rod.

[0010] Furthermore, a rotating disk is fixedly connected to the middle of the threaded rod for rotating the threaded rod.

[0011] Furthermore, end plates are respectively fixedly connected to both ends of the connecting column. The end of the threaded rod is rotatably connected to the end plate.

[0012] Furthermore, a supporting block is hinged to the connecting column. The supporting block abuts against the side surface of the small arm.

[0013] Furthermore, a backing plate is fixedly connected to the resisting block.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. Compared with the traditional pipeline detector that only detects on the ground, it can detect the underground pipeline situation in real time during the excavation operation, solving the problem that pipelines with a relatively deep burial depth cannot be detected.

[0016] 2. When the safety control device detects the existence of underground pipelines during the excavation operation, it can control the excavation machinery to stop forcibly, reducing the influence of the operator's operation technical level, greatly reducing the hidden danger of pipeline damage, and improving the construction safety.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Please refer to Figure 1 、 Figure 2 As shown, a safety control device for detecting underground pipelines includes an excavator and a pipeline detector 3. The excavator includes a fuselage, a boom, a forearm 1 and a bucket 2, and further includes a fixing frame 4, two mounting blocks 5, a rotating block 6 and a control system. The fixing frame 4 is fixed inside the forearm 1 and above the bucket 2. The mounting blocks 5 are installed at both ends of the fixing frame 4. The rotating block 6 is rotatably installed on the mounting blocks 5. The pipeline detector 3 is hingedly installed on the rotating block 6 and is located on both sides of the bucket 2 respectively. The control system is installed in the cab of the fuselage. The control system is connected to the pipeline detector 3 through a signal transmission wire, and is used to receive the signal of the pipeline detector 3 to control the shutdown of the excavator.

[0023] The working principle is as follows: Fix the fixing frame 4 on the forearm 1, and hingedly install two pipeline detectors 3 on the rotating block 6. Adjust the orientation of the pipeline detectors 3 according to the width of the bucket 2, so that the two pipeline detectors 3 face the middle of the bucket 2 and have an overlapping part. The control system is used to control the start and stop of the excavating machinery. Connect the signal receiver to the control system with a signal transmission wire. To prevent damage to the signal receiver and the wire during the operation of the excavating machinery, the signal receiver must be enclosed and protected, and at the same time, the signal transmission wire should be reasonably arranged and enclosed and protected. When the excavating machinery is operating, start the safety control device. The signal receiver can emit signals in real time during the operation of the machinery to detect the pipelines under the bucket 2. When the underground pipelines are detected by the pipeline detector 3, the signal is transmitted to the control system to issue an alarm and forcibly shut down the excavating machinery, indicating that there are underground pipelines near this position, and corresponding measures should be taken, such as manual excavation, pipeline protection and other measures.

[0024] In this embodiment, as Figure 2 shown, the fixing frame 4 includes two parallel fixing plates 7, a connecting column 8, two adjusting rods 9 and a resisting block 10. The connecting column 8 passes through the two fixing plates 7 and is fixedly connected to the fixing plates 7. The adjusting rods 9 are respectively threadedly connected to the fixing plates 7. The resisting block 10 is fixed at the end of the adjusting rod 9. The resisting block 10 is pressed against the forearm 1 through the adjusting rod 9. A locking nut 11 is threadedly connected to the adjusting rod 9. Rotate the adjusting rod 9 to press the resisting block 10 against the forearm 1, and use the locking nut 11 to closely adhere to the fixing plate 7 to fix the adjusting rod 9, which is convenient for disassembling and installing the fixing frame 4 for use on other excavators.

[0025] In this embodiment, as Figure 2As shown, the mounting block 5 is slidably connected to both ends of the connecting column 8. A threaded rod 12 arranged in parallel with the connecting column 8 is rotatably connected to the fixing plate 7. The two ends of the threaded rod 12 are symmetrically threaded, and the mounting blocks 5 are symmetrically and threadedly connected to the threaded rod 12. By adjusting the threaded rod 12, the mounting blocks 5 can be moved to approach or move away from each other simultaneously, so that the pipeline detector 3 can adapt to buckets 2 of different sizes, and the applicability is stronger.

[0026] In this embodiment, please refer to Figure 2 As shown, a rotating disk 13 is fixedly connected to the middle of the threaded rod 12 for rotating the threaded rod 12. Using the rotating disk 13 to rotate the threaded rod 12 facilitates adjusting the distance between the mounting blocks 5.

[0027] In this embodiment, please refer to Figure 2 As shown, end plates 14 are respectively fixedly connected to both ends of the connecting column 8, and the ends of the threaded rod 12 are rotatably connected to the end plates 14. Using the end plates 14 can prevent the mounting blocks 5 from sliding out of both ends of the fixing frame 4.

[0028] In this embodiment, please refer to Figure 2 As shown, a support block 15 is hinged to the connecting column 8, and the support block 15 abuts against the side surface of the small arm 1. Using the support block 15 to abut against the small arm 1 makes the fixing frame 4 more firmly fixed to the small arm 1.

[0029] In this embodiment, please refer to Figure 2 As shown, a backing plate 16 is fixedly connected to the abutting block 10. The backing plate 16 is made of hard plastic to increase the friction between the abutting block 10 and the small arm 1, and the fixing frame 4 is fixed more firmly.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
