Description

Technical Field

[0001] The utility model relates to the technical field of rainwater and sewage pipe cleaning, in particular to a stable base. Background Art

[0002] Trenchless repair of urban rainwater and sewage pipes often involves well chamber dredging operations. When the silt, garbage, stones, etc. inside the pipe are washed to the bottom of the well chamber by the dredging vehicle, due to the lack of well chamber slag removal tools at this stage, in most cases only manual cleaning is used. When the well mouth is small, the working space is insufficient, the water flow is large, etc., manual cleaning is impossible or difficult, and generally a grabbing device is used to carry out the grabbing operation from the inspection well mouth.

[0003] When dredging equipment is used from the wellhead, the grabbing device will experience instantaneous movement during the process of grabbing garbage and unloading due to changes in gravity and the movement of the hydraulic grab bucket. The stability of the connection with the ground is poor, which poses certain safety hazards and reduces the dredging efficiency. Utility Model Content

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0016] Reference Figure 1 and Figure 2 A stable base comprises a shock-absorbing seat 1, the top of the shock-absorbing seat 1 is open, a shock-absorbing plate 2 is slidably connected to the inner wall of the shock-absorbing seat 1, a spring 3 is fixedly connected between the bottom of the shock-absorbing plate 2 and the shock-absorbing seat 1, the top of the shock-absorbing plate 2 is used to be connected to the supported member, and a moving wheel 4 is rotatably installed on the bottom of the shock-absorbing plate 2 through two side plates 8; both side plates 8 of the moving wheel 4 are fixedly connected to a positioning box 10, a positioning groove 11 is opened on the inner wall of the positioning box 10, a positioning plate 12 is slidably connected to the side wall of the positioning groove 11, a second spring 13 is fixedly connected between the side wall of the positioning plate 12 and the positioning groove 11, and the positioning groove 11 is communicated with the inner cavity of the shock-absorbing seat 1;

[0017] See also Figure 3 When in use, the stable base is connected to the bottom of the sub-bracket, which is directly used to connect and operate the hydraulic grab A. Through the above arrangement, when the hydraulic grab A grabs the sludge garbage and is pulled upward, the total gravity of the hydraulic grab A will increase, and the shock-absorbing plate 2 will press down to squeeze the airflow in the shock-absorbing seat 1, and make this part of the airflow be filled into the positioning groove 11, thereby pushing the positioning plate 12 to extend outward, thereby clamping and fixing the moving wheel 4 from both sides at the same time, ensuring that the moving wheel 4 will not move at this time, and further improving the stability of the main frame.

[0018] Reference Figure 2 The damping plate 2 is fixedly connected with limiting rods 5 on all sides, and the bottom of the limiting rods 5 passes through the damping seat 1.

[0019] In the above embodiment, when the total gravity of the hydraulic grab A will increase, the shock absorbing plate 2 on the base will be squeezed into the shock absorbing seat 1, thereby driving the limit rod 5 to move downward, so that the limit rod 5 contacts the ground, thereby limiting the four sides of the moving wheel 4, avoiding the moving wheel 4 from accidentally sliding, improving the stability of the main frame, and ensuring safety during dredging.

[0020] An adsorption groove 6 is provided in the damping plate 2 , and an adsorption port 7 is provided at the bottom of the limiting rod 5 . The adsorption port 7 is communicated with the inner cavity of the adsorption groove 6 .

[0021] In the above embodiment, after the hydraulic grab unloads the garbage, the force on the base is reduced. At this time, the shock absorbing plate 2 moves upward under the action of the spring 3. At this time, the volume of the cavity connected to the adsorption groove 6 and the adsorption port 7 increases, generating a local negative pressure, so that suction is generated at the bottom of the adsorption port 7, so that the bottom of the limit rod 5 fits more firmly with the ground, which can prevent the device from moving abnormally at the moment of unloading.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
