Description

Technical Field

[0001] The utility model relates to the technical field of garden engineering, in particular to a detection trolley for detecting the direction of underground pipelines and cables. Background Art

[0002] With the acceleration of urbanization and the continuous deepening of urban infrastructure construction, underground pipelines are an important part of urban infrastructure, including various pipelines and lines such as water supply, drainage, power communication, etc. Due to the long history and the loss of relevant archives, the distribution of underground pipelines is unknown. If construction is carried out directly, it is easy to dig up pipelines and cables, causing construction accidents. Therefore, underground pipeline detection is required before construction.

[0003] At present, the detection of underground pipelines requires the use of underground pipeline detectors. A signal generator is placed on the exposed metal pipes, and the detectors hold the detectors and scan the ground. When the detector is directly above the metal pipes, the detected signal is the strongest, indicating that the current location is the location of the underground pipeline. Since the detector needs to keep the probe vertical to the ground, the detectors cannot keep their hands completely vertical for a long time. For metal pipes with larger diameters, the detection accuracy can be guaranteed. However, if the detector cannot be kept vertical for pipes with smaller diameters, the signal reception will be sometimes strong and sometimes weak, which is very unfavorable for judging the direction of the pipeline.

[0004] Therefore, in view of the above shortcomings, it is necessary to provide a detection vehicle for detecting the direction of underground pipelines and cables. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] A detection vehicle for detecting the direction of underground pipelines and cables, combined with Figure 1 , Figure 2 , including a vehicle body 1, a flag frame 2, a bracket 3, a seat clamp 4, a pendulum 5 and an identification flag 7. The flag frame 2 is welded on both sides of the inner cavity of the vehicle body 1, and several identification flags 7 are plugged into the flag frame 2. The bracket 3 is welded to the middle upper end of the flag frame 2. The seat clamp 4 is rotatably connected to the inner side of the bracket 3. A detector 6 is placed on the seat clamp 4. The detector 6 uses a Vloc3-pro underground pipeline detector.

[0030] Combination Figure 1 , Figure 2 The vehicle body 1 is a square shell, and a front cavity 11 is provided at the front of the vehicle body 1. The unused pendulum 5 and the detector 6 are placed in the front cavity 11. The height of the front cavity 11 is lower than the overall height of the vehicle body 1, which is convenient for the detector to take out the pendulum and the detector 6. A handle 12 is fixedly connected to the side of the vehicle body 1 away from the front cavity 11. The height of the handle 12 is higher than the height of the vehicle body 1, which is convenient for the detector to push the vehicle body 1 to move.

[0031] Combination Figure 1 , Figure 6 The two sides of the rear end of the bottom of the vehicle body 1 are rotatably connected with fixed wheels 13, and the two sides of the front end of the bottom of the vehicle body are rotatably connected with universal wheels 14. A spring 15 for shock absorption is fixedly connected between the fixed wheels 13 and the universal wheels 14 and the bottom of the vehicle body 1. The provision of the spring 15 enables the detection vehicle to travel on uneven roads, such as grass or land, thereby improving the applicable scope of the detection vehicle. The vehicle body 1 is provided with a long swing groove 16 directly below the seat clamp. The bottom probe of the detector 6 passes through the swing groove 16 and extends out of the vehicle body 1. The length of the swing groove 16 is greater than the width of the bottom probe of the detector 6. The provision of the swing groove 16, on the one hand, enables the probe of the detector 6 to contact the ground as much as possible, thereby improving the acquired signal strength and increasing the detection accuracy. On the other hand, it can provide a space for the swing of the detector 6 when the vehicle moves, thereby avoiding damage to the detector 6 caused by collision. In addition, on uneven roads, it can also provide a space for the probe of the detector 6 to remain vertical to the ground.

[0032] Combination Figure 1 , Figure 2 The flag stand 2 is a metal frame in the shape of a gate. The bottom and one side of the top of the flag stand 2 are fixedly connected to the vehicle body 1. The bottom legs of the flag stand 2 are not connected to one side of the vehicle body 1 to leave space for placing the pendulum 5. A plurality of circular sockets 21 are provided at intervals on the top of the flag stand 2 near the side connected to the vehicle body 1 for placing the identification flag 7. The bracket 3 is a metal bracket in the shape of a gate. The top of the bracket 3 is a hollow structure. By designing the flag stand 2 and the bracket 3 in the shape of a gate, the weight of the vehicle is reduced while ensuring excellent structural strength and load-bearing capacity, so that it is easy to push and move on and off the tricycle.

[0033] Combination Figure 3 , Figure 5 The seat clamp 4 is a concave rod, and the bottom of the display of the detector 6 is embedded in the groove of the seat clamp 4. The design of the seat clamp 4 can accommodate the detector 6 at the lowest cost and is convenient to take. A rotating shaft 41 is fixedly connected to one side of the seat clamp 4, and one end of the rotating shaft 41 passes through the bracket 3 and is threadedly connected to the pendulum 5. The rotating shaft 41 is covered with a bearing, and the bearing is embedded in the bracket 3. The seat clamp 4 and the pendulum 5 are connected by the rotating shaft 41, so that the seat clamp 4 and the pendulum 5 can be detached and separated, and then stored in the front cavity 11 to prevent the car from being damaged due to the large swing amplitude of the pendulum 5 during transportation on the tricycle. At the same time, different seat clamps 4 can be replaced according to the different models of the detector 6 used, which has stronger applicability. At the same time, the combination of bearings makes the seat clamp 4 and the pendulum 5 easier to deflect, and the self-adjustment is more accurate.

[0034] Combination Figure 4 , Figure 5, one end of the seat clamp 4 on both sides of the detector 6 is welded with a reinforcing rod 42, which connects the two seat clamps 4 and is located below the detector 6 display. The reinforcement rod 42 can improve the structural strength of the seat clamp 4 and reduce the torque on the rotating shaft 41. The pendulum 5 is a structure with a thin rod at the top and a lead ball at the bottom. The total weight of the pendulum 5 is greater than the weight of the detector. When in use, the detector 6 is placed on the seat clamp 4, and the signal generator is clamped on the exposed metal pipe or cable end. The detection personnel push the trolley while observing the indication on the detector 6 display. At this time, the pendulum 5 begins to swing under the action of inertia. Due to the slow movement of the trolley and the action of gravity, the swing amplitude of the pendulum 5 is small, so that the detector 6 can be basically stable and vertical to the ground, thereby effectively improving the detection accuracy of small diameter pipes and even cables. When it is found that the signal strength reaches the value set by the detector, it means that there is a pipeline or cable directly below the current position. At this time, the identification flag is removed and inserted into the ground, or placed on the ground to provide a clear identification for the surveying and mapping personnel.

[0035] Combination Figure 1 , Figure 2 The identification flag 7 is composed of a cylindrical plug rod and a steel sheet. The steel sheet is fixedly connected to one side of the top of the plug rod. The plug rod is inserted into the insertion hole 21 to store the identification flag 7. The plug rod can be inserted into the ground to serve as a mark. The steel sheet on the identification flag 7 has different shapes, such as rectangle, diamond or triangle. When the identification flag 7 is inserted into the ground, the length direction of the steel sheet is adjusted to the direction of the pipeline according to the direction of the signal strength. By arranging the identification flags at intervals for multiple times, a very clear mark can be provided for the surveying and mapping personnel, and then the specific direction of the underground pipeline can be determined, providing a clear location for subsequent construction, avoiding the loss of residents or enterprises caused by digging up the pipeline.

[0036] The utility model has a simple structure and low manufacturing cost, and will not cause too much additional economic burden to the detection unit. The pendulum 5 is cleverly used to automatically control the vertical position of the detector 6, and the trolley is used to free the hands of the detection personnel, which greatly reduces the manpower investment. In addition, the detector 6 itself is not modified, and the detection personnel have low difficulty in getting started, and it is highly practical.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
