Description

Technical Field

[0001] The utility model relates to the technical field of channel pouring construction platforms, and more specifically to a construction platform based on port channel pouring. Background Art

[0002] The construction platform for port channel pouring is a device specially used to provide a stable and safe construction environment in river regulation projects, especially in the process of channel pouring. The design of this type of construction platform usually takes into account the safety and stability during the pouring process to ensure the smooth progress of the construction process. Underwater concrete pouring requires the installation of a steel cage and a spliced ​​conduit in the pouring hole, and the concrete is poured into the inside of the filling hole along the conduit. During the pouring process, the spliced ​​conduit should determine the time and length of the conduit removal according to the concrete supply situation to prevent slag, mud, and honeycomb accidents in the pile body.

[0003] The installation of the concrete filling conduit is generally done by directly hoisting the spliced ​​conduit to a position about 30 to 40 cm from the bottom of the hole. Direct hoisting of the conduit requires manual confirmation of the central position of the conduit corresponding to the filling hole, and the conduit will swing after hoisting, affecting the filling of cement inside the filling hole. In view of this, we propose a construction platform based on port channel pouring. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a construction platform based on port channel pouring to solve the technical problems of inconvenient positioning and stable installation in the current catheter lifting process.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a construction platform based on port channel pouring, comprising a workbench divided into a movable plate and a support plate, a plurality of synchronous motors are evenly arranged on the upper surface of the workbench, one end of the output shaft of the synchronous motor is fixedly connected to a control shaft, a limit rod is arranged on the outer side of the control shaft, a hopper hole is opened in the middle of the support plate, a plurality of movable holes are evenly arranged on the outer side of the hopper hole, a spring is arranged inside the movable hole, a push rod is fixedly connected to the lower end of the spring, an inverted truncated cone-shaped focusing block is fixedly connected to the lower surface of the push rod, and a maximum diameter of the focusing block is opened in the middle of the movable plate. The adjusting screw mandrel is provided with a plurality of holes which match the holes at the bottom of the adjusting screw mandrel, and a vertical hole corresponding to the hopper hole is formed inside the focusing block, and a universal wheel is provided below the movable plate; the upper surface of the supporting plate is movably connected with a lever through a supporting shaft, one end of the lever is fixedly connected with a contact block, a moving rod is provided at the inner edge of the supporting plate, the other end of the lever is movably connected with the shaft through a sleeve and the upper end of the moving rod, the interior of the moving rod is movably connected with a connecting rod, the lower end of the connecting rod is fixedly connected with the supporting rod, the upper end of the moving rod is provided with a connecting hole which is connected with the interior of the moving rod, the interior of the sleeve is provided with an air hole corresponding to the connecting hole, and the other end of the air hole passes through the upper surface of the sleeve.

[0006] The utility model pushes the workbench to move it roughly until the focusing block is located above the installed steel cage, then starts the synchronous motor to drive the control shaft to rotate and control the support plate to descend vertically and stably, so that the focusing block with a larger diameter and unadjusted position is subjected to lateral force when in contact with the steel cage, and drives the workbench as a whole to move through the universal wheels until the focusing block completely falls to the point where the workbench no longer moves, and the focusing block stops moving downward after being in direct contact with the steel cage on all sides, and forces the push rod to compress the spring inside the movable hole and gradually move upward inside the movable hole during the continuous downward movement of the support plate. When the filling hole is in the middle, it can be confirmed that the middle position of the focusing block is the center position of the filling hole, and the filling catheter can be vertically installed into the filling hole through the focusing block and the hopper hole. After the ejector rod is completely moved out of the movable hole, it will contact the contact block. At this time, the lever slowly deflects under the action of the support shaft on the upper surface of the support plate, and makes the air hole and the connecting hole not correspond. At this time, the moving rod continues to move downward to compress the air inside the moving rod, and forces the connecting rod to drive the support rod downward to contact the ground, avoiding the workbench from shifting under the action of the universal wheel during the installation of the catheter, which is convenient for positioning and vertically placing the filling catheter.

[0007] Preferably, a connecting tube is provided at the upper end of the perfusion catheter, and a spiral flow groove is provided inside the connecting tube.

[0008] Preferably, the hopper hole is a hole that is wide at the top and narrow at the bottom to adapt to the filling hopper, and the lower end of the hopper hole has the same diameter as the vertical hole inside the focusing block.

[0009] Preferably, the lower surface of the contact block is located at the upper opening of the movable hole, the end of the lever close to the contact block is lower, and the support shaft position on the upper surface of the support plate is close to the contact block.

[0010] Preferably, the inner wall of the support plate is provided with a spiral groove corresponding to the control shaft, the lower end of the control shaft is movably connected to the movable plate, the limit rod passes through the support plate and the two ends are respectively fixedly connected to the synchronous motor and the movable plate.

[0011] Preferably, the maximum diameter of the focusing block is larger than the inner diameter of the steel cage in the filling hole.

[0012] Preferably, the support rod passes through the movable plate, and the bottom end of the support rod is higher than the bottom end of the universal wheel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model designs a workbench that can be moved under force. When the focus block is in contact with the steel cage, the placement position of the workbench and the focus block is adjusted until the outer surface of the focus block fits with the outer surface of the steel cage, thereby determining the installation center position of the filling catheter. At the same time, under the action of the vertical filling hole inside the focus block, the catheter is kept vertically centered and hoisted. At the same time, after the focus block is fitted with the steel cage, the contact block is lifted up by the push rod, and at the same time, the other end of the lever is pressed down and drives the shaft sleeve to deflect so that the connecting hole does not correspond to the air hole. When the air inside the moving rod cannot be released and is continuously pressurized, the connecting rod and the support rod are driven to move down and contact the ground, thereby preventing the workbench from shifting during the installation and use of the catheter.

[0015] 2. The utility model provides a spiral flow groove inside the connecting pipe, so that when the filling hole is initially filled, the filled concrete has a spiral force, and can be thrown out to the surroundings of the steel cage when the lower end is higher than the bottom of the hole when discharged, thereby improving the concrete filling effect.
