Description

Technical Field

[0001] This utility model relates to the technical field of construction safety protection devices, and in particular to a portable outdoor engineering inspection well safety warning device. Background Technology

[0002] During construction or maintenance of municipal pipelines, safety barriers must be set up at openings. The purposes are threefold: first, to create a warning zone to prevent unauthorized personnel from entering; second, to allow workers to concentrate on their work and reduce the impact of the external environment; and third, to shield the work area and reduce the attention of outsiders.

[0003] Guardrails are common safety fencing facilities. Guardrails are transported and installed as a whole. For openings with high protection requirements, at least 3 to 4 guardrails are needed for complete enclosure. Since guardrails are mostly over 1 meter in length and relatively large in size, they are generally transported in trucks with sidecars or box trucks. Handling, carrying and transporting them are inconvenient and cannot achieve the purpose of portable installation. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides a portable outdoor engineering inspection well safety warning device.

[0005] The portable outdoor engineering inspection well safety warning device provided by this utility model adopts the following technical solution: A portable outdoor engineering inspection well safety warning device includes two mounting frames arranged vertically and parallel to each other. A vertically arranged support rod is detachably installed between the two mounting frames. A warning strip is also connected between the two mounting frames. A support frame is detachably installed on the mounting frame. A clamp for clamping and fixing the top plate of the inspection well at the well opening is provided at the end of the support frame away from the mounting frame.

[0006] Optionally, the mounting frame includes a main support rod, with secondary support rods at both ends of the main support rod. Vertically arranged inserts are fixed to the main support rod and the secondary support rods respectively. The vertical support rods can be detachably inserted into the two corresponding inserts.

[0007] By adopting the above technical solution, the mounting frame forms a structure with three sides enclosed and one side open. The enclosed side, together with the warning tape, effectively seals off the work area, while the open side facilitates the passage of workers or the transportation of materials and tools.

[0008] Optionally, mounting seats are fixedly connected to both ends of the main support rod, and vertically arranged rotating shafts are rotatably connected to the mounting seats. The distance from one rotating shaft to the main support rod is greater than the distance from the other rotating shaft to the main support rod, and one end of the auxiliary support rod is fixedly connected to the rotating shaft.

[0009] By adopting the above technical solution, the secondary support rod can be folded relative to the main support rod, and the two secondary support rods can also be stacked. Rotation or stacking does not affect each other, further improving the convenience of carrying and transportation.

[0010] Optionally, the mounting base includes two ear plates and a base plate. The two ear plates are fixed to the main support rod, and the base plate is perpendicular to the main support rod. The pivot is rotatably connected between the upper and lower ear plates, and the base plate is used to limit the rotation range of the secondary support rod to more than 90°.

[0011] By adopting the above technical solution, a C-shaped mounting base is set up, which facilitates the control of the unfolding angle of the secondary support rod, thereby making it easier to fold or unfold the secondary support rod.

[0012] Optionally, the support frame includes a flat support rod lying on the ground, an inclined support rod installed above the flat support rod, and U-shaped pipe clamps installed at the ends of both the flat support rod and the inclined support rod. The U-shaped pipe clamps can be detachably clamped onto the main support rod or the secondary support rod, and the clamp is set at the end of the flat support rod away from the U-shaped pipe clamp.

[0013] By adopting the above technical solution, the flat bracing rods and diagonal bracing rods, together with U-shaped pipe clamps and fixtures, provide effective support, thereby effectively fixing the position and shape of the assembled mounting frame.

[0014] Optionally, the clamp includes a guide tube and an extension rod. The guide tube is vertically fixed to the top surface of the flat support rod, and the extension rod slides through the guide tube and the flat support rod. A clamp is fixed to the bottom end of the extension rod, and a hand-tightening screw for securing the extension rod is installed on the guide tube via a transverse thread.

[0015] By adopting the above technical solution, the clamp is inserted into the well, then the extension rod is pulled upwards, and the position of the extension rod is fixed by turning the hand-tightening screw. The clamp is very easy to operate and the flat support rod is effectively fixed.

[0016] Optionally, both the extension rod and the guide tube have semi-circular cross-sections, with the curved surface of the extension rod facing the side closest to the U-shaped tube clamp.

[0017] By adopting the above technical solution, the arc-shaped surface of the extension rod can fit tightly against the inner wall of the wellhead, improving the stability of the fit between the extension rod and the top plate of the inspection well at the wellhead.

[0018] Optionally, a fixing ring is fixed to the top of the extension rod and the outer wall of the guide tube, and a connecting rope is connected between the two fixing rings.

[0019] By adopting the above technical solution, the connecting rope serves to connect the guide tube and the extension rod, preventing the extension rod from accidentally falling into the inspection well.

[0020] Optionally, the clamp includes a flat clamp plate that is laterally fixed to the extension rod, with an inclined brace plate obliquely fixed between the end of the flat clamp plate away from the extension rod and the bottom end of the extension rod.

[0021] By adopting the above technical solution, the flat clamp plate makes frictional contact with the bottom surface of the manhole top plate, and the inclined brace plate supports the flat clamp plate, ensuring stable contact between the flat clamp plate and the manhole.

[0022] Optionally, the top surface of the flat brace is fixedly connected to a second insert at an angle, and the diagonal brace can be detachably inserted into the second insert.

[0023] By adopting the above technical solution, it is convenient to store or transport the inclined insertion rod and the flat support rod separately, thereby reducing the space occupied.

[0024] This utility model consists of multiple components, making it very convenient to store, fold, transport, and carry. It eliminates the need for trucks or vans, allowing it to be carried by ordinary passenger vehicles, thus improving transportation convenience and adaptability. The on-site assembly process is very simple, requiring only basic training for construction personnel. The convenient installation and disassembly procedures improve construction efficiency. This utility model is detachably connected to the manhole top plate, uniquely utilizing the manhole top plate as a support, ensuring reliable stability after installation. This utility model not only serves as a warning but also provides a safe working area for construction personnel, reducing interference from the external environment. Attached Figure Description

[0030] The following combination Figures 1-4 The present invention will be described in further detail below.

[0031] Reference Figures 1-4 A portable outdoor engineering inspection well safety warning device is installed near the inspection well opening, forming a three-way enclosure around the opening, with only one side having a passage for operation.

[0032] The portable outdoor engineering inspection well safety warning device includes a mounting frame 1, a vertical support rod 2, a warning tape 3, a support frame 4, and a clamp 5 that cooperate with each other.

[0033] There are two mounting brackets 1 arranged vertically in parallel. When unfolded, the mounting bracket 1 forms a U-shape. The mounting bracket 1 includes one main support rod 10 and two secondary support rods 11. In the folded state, the secondary support rods 11 are parallel to the main support rod 10; in the unfolded state, the secondary support rods 11 are perpendicular to the main support rod 10. A mounting base 12 is fixed to each end of the main support rod 10.

[0034] In this embodiment, the mounting base 12 is a C-shaped plate, which includes two ear plates and a base plate. The two ear plates are fixedly connected to the main support rod 10, and the base plate is perpendicular to the main support rod 10. A vertically arranged rotating shaft 13 is rotatably connected between the upper and lower ear plates. The distance from one rotating shaft 13 to the main support rod 10 is greater than the distance from the other rotating shaft 13 to the main support rod 10. The auxiliary support rod 11 is fixedly connected to the rotating shaft 13. The base plate is used to limit the rotation range of the auxiliary support rod 11 to more than 90°.

[0035] Both ends of the main support rod 10 and the ends of the auxiliary support rod 11 away from the main support rod 10 are vertically fixed with inserts 14. Multiple vertical support rods 2 are provided, and each vertical support rod 2 can be detachably inserted into two corresponding inserts 14 to form a three-dimensional structure. Multiple warning tapes 3 are arranged side by side, and the top and bottom ends of each warning tape 3 are respectively connected to two corresponding main support rods 10 or two auxiliary support rods 11. A gap is provided between two adjacent warning tapes 3.

[0036] There are three support frames 4 in total, and the three support frames 4 correspond one-to-one with the three sides of the mounting frame 1. The support frame 4 includes a flat support rod 40 that is laid flat on the ground. The flat support rod 40 is perpendicular to the corresponding secondary support rod 11 or main support rod 10. An inclined support rod 41 is installed on the top of the flat support rod 40. A second insert 42 is fixedly connected to the top surface of the flat support rod 40. The inclined support rod 41 can be detachably inserted into the second insert 42. U-shaped pipe clamps 43 are installed at the ends of the inclined support rod 41 and the flat support rod 40. The U-shaped pipe clamps 43 can be detachably clamped onto the corresponding main support rod 10 or secondary support rod 11, and the clamping position is located in the middle of the main support rod 10 or secondary support rod 11.

[0037] The clamp 5 is located at the end of the flat support rod 40 away from the U-shaped pipe clamp 43. The clamp 5 includes a guide tube 50 that is vertically fixed to the top surface of the flat support rod 40. The guide tube 50 has a semi-circular cross-section. An extension rod 51 is vertically slidably inserted inside the guide tube 50. The extension rod 51 is also slidably inserted into the flat support rod 40. The extension rod 51 has a semi-circular cross-section and is adapted to the guide tube 50. The arc-shaped surface of the extension rod 51 faces the side closer to the U-shaped pipe clamp 43 so that the extension rod 51 can fit against the wellhead sidewall.

[0038] A clamp 52 is fixedly connected to the bottom end of the extension rod 51. The clamp 52 includes a flat clamp plate 520 that is horizontally fixed to the extension rod 51. The top surface of the flat clamp plate 520 is provided with anti-slip texture. An inclined brace plate 521 is fixedly connected between the end of the flat clamp plate 520 away from the extension rod 51 and the bottom end of the extension rod 51. The brace plate 521 provides support for the flat clamp plate 520.

[0039] A hand-tightening screw 53 is installed on the guide tube 50 with a transverse thread. The hand-tightening screw 53 abuts against the extension rod 51 to limit the vertical movement distance of the extension rod 51. After the flat clamp 520 extends into the inspection well, it hooks onto the bottom surface of the inspection well top plate, while the flat support rod 40 is supported on the top surface of the inspection well top plate. By pulling the extension rod 51 upward, the flat clamp 520 can be tightly fitted to the bottom surface of the inspection well top plate. Then, by tightening the extension rod 51 with the hand-tightening screw 53, the flat support rod 40 and the flat clamp 520 can be fixed at the same time, thereby fixing the support frame 4 and the mounting frame 1.

[0040] A fixing ring 54 is fixedly attached to the top of the extension rod 51 and the outer wall of the guide tube 50. A connecting rope 55 is connected between the two fixing rings 54. In this embodiment, the connecting rope 55 is a spring rope. The connecting rope 55 serves to connect the guide tube 50 and the extension rod 51, preventing the extension rod 51 from accidentally falling into the inspection well.

[0041] The implementation principle of the portable outdoor engineering inspection well safety warning device of this utility model embodiment is as follows: First, before installing the safety device, open the inspection well cover, then unfold the auxiliary support rod 11 so that the auxiliary support rod 11 is perpendicular to the main support rod 10, insert the vertical support rod 2 into the two corresponding upper and lower inserts 14, at which time the warning tape 3 is in the unfolded state, and the main frame assembly is completed.

[0042] Subsequently, the three sets of clamps 5 are installed on the top plate of the inspection well at the wellhead in three directions. First, the clamp 52 is inserted into the inspection well, and then the extension rod 51 is pulled upward. After the flat clamp 520 is tightly attached to the bottom surface of the inspection well top plate, the hand-tightening screw 53 is rotated to make the hand-tightening screw 53 press against and fix the extension rod 51. At this time, the position of the flat support rod 40 is also fixed.

[0043] Finally, insert the diagonal brace 41 into the insert tube 42, and snap the main support rod 10 or the auxiliary support rod 11 into the corresponding U-shaped pipe clamp 43. Note that the clamp should be snapped into the middle position of the main support rod 10 or the auxiliary support rod 11. This completes the assembly of the safety device.

[0044] This safety device consists of multiple components, making it very convenient to store, fold, transport, and carry. It can be carried in a regular passenger vehicle without the need for a truck or van, thus improving transportation convenience and adaptability. The on-site assembly process is very simple, requiring only basic training for construction personnel. The convenient installation and disassembly procedures improve construction efficiency. The safety device is detachably connected to the manhole top, uniquely utilizing the manhole top as a support structure, ensuring reliable stability after installation. The device is enclosed on three sides and open on one side, allowing construction personnel to easily enter, exit, or transport materials and tools. This safety device not only serves as a warning but also provides a safe working area for construction personnel, reducing interference from the external environment.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
