Description

Technical Field

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

[0002] When carrying out road construction, underground pipeline maintenance or new projects, it is particularly important to understand the location and situation of underground pipelines. However, since underground pipelines are hidden underground and usually have limited understanding of them, underground pipeline detection is particularly important.

[0003] Among common underground pipeline detection methods, there is a detection method called underground pipeline marking method. Generally, it uses a detection trolley with a marking function. The detection trolley consists of a frame, wheels, a detection radar, a handrail, etc., and is very common in the field of pipeline detection; the marking function is realized by a marking mechanism, and the marking mechanism can spray out one of the marking substances such as pigments or paints, so as to visually mark the position of the pipeline, obtain the position and direction of the pipeline, and help construction workers for positioning and identification to avoid damage to the pipeline caused by misoperation of construction equipment.

[0004] According to the above idea, a Chinese utility model patent with the authorization announcement number CN 219625729 U discloses an underground pipeline detection device, which includes a trolley. A detector and an ink tank staggered from the detector are installed on the upper surface of the trolley. An inkjet mechanism is arranged on the lower surface of the ink tank. An air delivery pipe penetrates through the upper surface of the ink tank. A cylinder is installed at the upper end of the air delivery pipe. The cylinder has an open upper end structure. A piston in the shape of a disc is inserted at the opening of the cylinder. A movable rod is arranged on the upper surface of the piston. One end of the movable rod extends upward out of the opening of the cylinder and is provided with a push rod mechanism. The push rod mechanism includes a push handle hinged to one end of the movable rod. The lower end of the push handle extends obliquely downward and is rotatably installed with a universal joint fork. It can be realized that marking can be carried out by the method of pressing out ink by hand while moving forward.

[0005] Although the above solution can realize the marking function, it still has the following technical problems: a. The inkjet mechanism set is only applicable to the detection device in this document, is not convenient for disassembly and assembly, and cannot be installed on existing detection trolleys, resulting in a small scope of application and being unable to meet the needs of modification and installation of existing detection trolleys, and the use is not flexible enough; b. By the method of pushing the trolley with one hand and pressing with the other hand, pressing while walking, it is inconvenient for the staff to operate and not convenient to hold the whole machine with both hands. Especially in the case of poor construction road conditions, there are easily safety hazards such as falling; c. The method of using inkjet is only applicable to hardened road surfaces and is not applicable to non-hardened soil road surfaces. This is because after inkjet on the soil road surface, the ink will seep into the soil, resulting in the marking becoming unclear. Therefore, it is necessary to find a device that can be applicable to both hardened road surfaces and soil road surfaces. Summary of the Utility Model

[0040] Embodiment 1:

[0041] Regarding technical problems a and b, as Figure 1 - Figure 3 shown, this embodiment proposes a device for detecting underground pipelines in building construction, which includes a vehicle frame 1, and the vehicle frame 1 is provided with wheels 2; the vehicle frame 1 is connected with a handrail frame 4, and the top of the handrail frame 4 is connected with a handle 6; a detection radar 3 is arranged on the vehicle frame 1 for detecting underground pipelines; a marking mechanism 9 is also arranged at the rear end of the vehicle frame 1, and the marking mechanism 9 can visually mark the position of the pipeline, obtain the position and direction of the pipeline, and help construction workers for positioning and marking to avoid damage to the pipeline caused by misoperation of construction equipment.

[0042] In this embodiment, the top of the handrail frame 4 is connected with a handlebar frame 5, and the handlebar frame 5 has two groups of handles 6; the handlebar frame 5 has a space for installing a display screen 7, and the display screen 7 is electrically connected with the detection radar 3. The detection radar 3 mainly includes a power supply, a GPR main control system, a computer mainframe, a transmitter, a transmitting antenna, a receiver, a receiving antenna, a data cache unit, a positioning module, etc. The power supply, the computer mainframe, the transmitter, the data cache unit, and the positioning module are all connected with the GPR main control system. The transmitting antenna is connected with the transmitter, the receiver is connected with the data cache unit, and the receiving antenna is connected with the receiver. The positioning module is used to obtain the spatial position information of the ground penetrating radar and transmit the spatial position information to the GPR main control system. The GPR main control system is used to process the characteristic parameters and spatial position information, and the display screen 7 is used to display the detected information. The specific layout can be referred to in the appendix Figure 10 .

[0043] One structural form of the marking mechanism 9 can be the following structure, which includes:

[0044] The bottom support assembly plays a role in supporting the main body. The bottom support assembly includes a support 91, which is vertically arranged and detachably connected to the vehicle frame 1. In this embodiment, the detachable connection methods include, but are not limited to, plugging, clamping, bolting, etc. In this solution, bolting is preferably used, which is convenient for connecting to the vehicle frame 1 and is applicable to both the installation of new machines and the retrofit of old machines. When retrofitting an old machine, only need to drill holes in the original vehicle frame 1, and then the connection between the support 91 and the original vehicle frame 1 can be realized. One side of the support 91 is fixedly connected to one end of a frame 92, and the other end of the frame 92 is fixedly connected to a vertical plate 93. The frame 92 is a rectangular frame structure with a hollow interior to facilitate the spraying of marking pigments.

[0045] The support 91 is installed and connected in a detachable manner and is installed at the rear end of the vehicle frame 1, which will not affect the normal use of other parts. Whether it is the retrofit of old equipment or the installation of new machines, this mechanism can be well applied. The overall structure of this device is simple, the cost is low, and the practicability is high, and it can be actually applied to the surveying and mapping project.

[0046] And a container detachably connected to the frame 92, which contains pigments for marking. The container has a switch part that can open or close the container. The container has two options, which can be an automatic spray paint can 10 or a hopper 13, and can be selected according to the actual situation. For the detailed introduction, please refer to the following text.

[0047] It also includes a trigger assembly for realizing the opening and closing of the switch part. The trigger assembly includes a swing arm 95. A hinge seat 94 is fixedly connected to one side of the vertical plate 93, and the swing arm 95 is rotatably connected to the hinge seat 94. A first compression spring 96 is connected between the vertical plate 93 and the swing arm 95 to play a reset role. A hand brake 8 is installed on the handle 6, and one end of the brake cable 11 is connected to the hand brake 8, and the other end of the brake cable 11 freely passes through the vertical plate 93 and is connected to the swing arm 95. The vertical plate 93 is provided with a wire passing hole 111, and the brake cable 11 can pass through the wire passing hole 111. The hand brake 8 and the brake cable 11 are both conventional structures, and the hand brake 8 and the brake cable 11 used on common bicycles can be selected.

[0048] The working principle of the trigger assembly: In the initial state, the first compression spring 96 is not compressed. At this time, the upper end of the swing arm 95 is far away from the switch part. When the hand brake 8 is squeezed, the hand brake 8 can pull the swing arm 95 to rotate through the brake cable 11, and the first compression spring 96 is compressed. At this time, the upper end of the swing arm 95 approaches and presses the switch part to realize the opening of the switch part. When the hand brake 8 is released, the swing arm 95 automatically resets under the elastic force of the first compression spring 96 to realize the closing of the switch part.

[0049] As mentioned above, the container can be selected according to the actual situation. In some embodiments, for the condition of hard pavement, the container can be selected as the automatic paint spray can 10; the automatic paint spray can 10 has a nozzle. When the nozzle is pressed, automatic painting can be realized, and when released, the nozzle can be automatically closed; in this embodiment, in order to facilitate the installation of the automatic paint spray can 10, the following structure is also designed:

[0050] At least one set of arc-shaped supporting plates 97 is arranged on the frame 92. In this embodiment, two sets can be arranged; the arc-shaped supporting plates 97 are fixedly connected to the top of the frame 92 and have a radian adapted to the automatic paint spray can 10; the horizontally arranged automatic paint spray can 10 is placed on the arc-shaped supporting plates 97, and the nozzle of the automatic paint spray can 10 is arranged downward; the position of the nozzle is correspondingly arranged with the swing arm 95. When the operation trigger assembly is triggered, the pressing of the nozzle can be realized; in order to facilitate the positioning of the position of the automatic paint spray can 10, the automatic paint spray can 10 can be fixed by using a cable tie binding method, but this method may cause displacement. For this reason, a positioning plate 98 for horizontally limiting the automatic paint spray can 10 is also fixedly connected to the frame 92; the tail end of the automatic paint spray can 10 abuts against the end face of the positioning plate 98. In this way, when the nozzle is pressed, the automatic paint spray can 10 will not move horizontally, which is beneficial to the smooth progress of marking.

[0051] In this embodiment, considering that there is no vertical limiting component, during the movement of the vehicle frame 1, due to reasons such as bumps, the position of the nozzle may change, which will cause the drawn marking line to be incorrect; for this reason, the whole device further includes a pressing member for pressing and positioning the automatic paint spray can 10. The pressing member includes an inner rod 910 and a hollow outer rod 99. The bottom end of the outer rod 99 is fixedly connected to the frame 92, and the bottom end of the inner rod 910 is movably inserted into the outer rod 99. The inner rod 910 can rotate and / or move up and down relative to the outer rod 99; a set screw 991 for positioning the inner rod 910 is threadedly connected to the rod wall of the outer rod 99; when the position of the outer rod 99 is adjusted, the set screw 991 is tightened to realize the relative fixation between the inner rod 910 and the outer rod 99; a horizontally arranged cross arm 911 is connected to the top of the inner rod 910, and a first bolt 912 for pressing the automatic paint spray can 10 is threadedly connected to the cross arm 911.

[0052] During use, the automatic paint spray can 10 is placed on the arc-shaped supporting plate 97, and then the height of the inner rod 910 is adjusted and fixed with the set screw 991; then the first bolt 912 is screwed, and the automatic paint spray can 10 is pressed by the first bolt 912, so that the positioning and fixation of the position of the automatic paint spray can 10 can be realized.

[0053] Embodiment Two:

[0054] Continue to refer to the appendix Figure 4 - Figure 9, in some embodiments, for the dirt road surface condition, the container can be a hopper 13, and the hopper 13 is filled with lime powder; the top of the hopper 13 has a gland 12; the gland 12 can be separable from the hopper 13; the bottom end of the hopper 13 has a material leakage nozzle 131, and a material leakage channel is arranged inside the material leakage nozzle 131; it further includes a support frame 14 for supporting the hopper 13, and the hopper 13 is detachably connected to the support frame 14; the support frame 14 is of an inverted U-shaped structure; the support frame 14 is detachably connected to the frame 92; the material leakage nozzle 131 is provided with a slot, the slot is arranged horizontally, and a laterally movable plug board 132 is slidably arranged in the slot, the plug board 132 has a material passing hole 1321, and the material passing hole 1321 can be misaligned or aligned with the material leakage channel. When the material passing hole 1321 is misaligned with the material leakage channel, at this time, the switch part is in the closed state, and the lime powder cannot leak out; when the material passing hole 1321 is aligned with the material leakage channel, at this time, the switch part is in the open state, and the lime powder can leak out smoothly; one end of a second compression spring 134 is fixedly connected to the inner wall of the support frame 14, one end of the plug board 132 is connected with a guide post 133, the guide post 133 freely passes through the second compression spring 134 and is slidably connected to the support frame 14, a sliding hole is formed in the support frame 14, and the guide post 133 is slidably connected to the sliding hole; the other end of the second compression spring 134 presses against the edge of the plug board 132; the position of the plug board 132 is correspondingly arranged with the swing arm 95. When the operation trigger assembly is triggered, the plug board 132 can be pressed, thereby realizing the switching of the material leakage channel from the closed state to the open state.

[0055] Regarding the detachable connection method of the above-mentioned support frame 14, the following structure can be selected: a positioning groove 921 is formed in the frame 92, a limiting boss 141 is fixedly connected to the side wall of the support frame 14, the frame 92 can be adaptively inserted into the positioning groove 921, and the bottom end of the boss 141 is clamped at the top of the positioning groove 921 to play a positioning role.

[0056] Considering that the ash hopper 13 may bounce up and down when encountering bumpy road conditions, in this embodiment, the ash hopper 13 is also provided with a corresponding pressing member. Most of the main structures of this pressing member and the corresponding pressing member of the automatic paint spray can 10 are the same. That is, the pressing member also includes an inner rod 910 and a hollow outer rod 99. The bottom end of the outer rod 99 is fixedly connected to the frame 92, and the bottom end of the inner rod 910 is movably inserted into the outer rod 99. The inner rod 910 can rotate and / or move up and down relative to the outer rod 99; a set screw 991 for positioning the inner rod 910 is threadedly connected to the rod wall of the outer rod 99; a horizontally arranged cross arm 911 is connected to the top of the inner rod 910, and a sleeve 914 is bolted to the cross arm 911. The sleeve 914 is connected to the cross arm 911 through a fastening bolt 913; a second bolt 915 for pressing the pressing cover 12 is threadedly connected to the sleeve 914; the setting of the sleeve 914 can achieve horizontal expansion and contraction, which is beneficial to adjusting the position of the second bolt 915. After the second bolt 915 is pressed down, it can achieve two functions. One is to fix the pressing cover 12 on the top of the ash hopper 13 to block the internal lime powder; the other is to vertically position the entire ash hopper 13 and the support frame 14.

[0057] It should be noted that regarding the connection between the support frame 14 and the ash hopper 13, the following structural form can be adopted: The top of the support frame 14 has a central hole, and the material leakage nozzle 131 is inserted and connected to the central hole.

[0058] Embodiment III:

[0059] Continue to refer to the appendix Figure 4 - Figure 9 For technical problem c, in this embodiment, considering the switching and installation between containers, on the basis of Embodiment II, at least one set of arc-shaped supporting plates 97 for fixing the automatic paint spray can 10 are further provided on the frame 92, and the arc-shaped supporting plates 97 are fixedly connected to the top of the frame 92. Similarly, in this embodiment, a positioning plate 98 can also be designed as in Embodiment I, and the positioning plate 98 is used to limit the tail of the automatic paint spray can 10. In this way, by setting both the arc-shaped supporting plates 97 and the support frame 14, the installation of different containers can be realized; when it is necessary to install the automatic paint spray can 10, the support frame 14 and the ash hopper 13 can be removed; when it is necessary to install the ash hopper 13, the automatic paint spray can 10 is removed, and the support frame 14 and the ash hopper 13 can be installed.

[0060] It can be seen that this device adopts a unique and reasonable configuration, which can realize the installation of the automatic paint spray can 10 or the ash hopper 13. Thus, the marked pigments can be selected according to different actual environments. For hard road surfaces with good road conditions, the container can be selected as the automatic paint spray can 10, and for muddy road surfaces with poor road conditions, the container can be selected as the ash hopper 13. It is flexible to use and has little limitation, and different pigments can be selected according to different actual situations for marking.

[0061] Principle of the concept of this solution:

[0062] By means of pulling the brake wire 11 with the hand brake 8, the action of the trigger assembly is realized. It is convenient for the staff to operate. Just press or release the hand brake 8 at the handle 6 to achieve it. Both hands can effectively control this machine, which can effectively solve the technical problem that in the case of poor construction road conditions of the existing device, safety hazards such as falling are likely to occur, and ensure the safety and convenience of driving control.

[0063] Although the specific implementation manners of the utility model are described above in conjunction with the drawings, it is not a limitation on the protection scope of the utility model. Based on the technical solution of the utility model, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the utility model.
