Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a large-volume concrete pouring device for an ultra-deep foundation pit. Background Art

[0002] Traditionally, before pouring, formwork is installed on the construction area according to design requirements to define the shape and size of the concrete. The cement is then transported to the construction site by a pump truck and delivered into the formwork through the pump truck's folding arm. In order for workers to adjust the direction of cement falling, a slurry delivery hose is fixedly connected to the bottom end of the folding arm. The drop position is adjusted by moving the slurry delivery hose away from one end of the folding arm.

[0003] During the implementation of this application, it was found that the technology has the following problems: the existing ultra-deep foundation pit large-volume concrete pouring equipment mostly installs the traction equipment on the outer end of the slurry delivery hose during use, which makes it easy for the traction mechanism to slip off the outer end of the slurry delivery hose when the subsequent hose stops conveying concrete, thereby reducing the practicality of the equipment.

[0004] Therefore, a large-volume concrete pouring device for ultra-deep foundation pit is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that most of the existing ultra-deep foundation pit large-volume concrete pouring devices install the traction equipment on the outer end of the slurry delivery hose during use, which makes the traction mechanism easily slip off the outer end of the slurry delivery hose when the subsequent hose stops conveying concrete. The present invention provides an ultra-deep foundation pit large-volume concrete pouring device.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A large-volume concrete pouring device for an ultra-deep foundation pit includes a concrete delivery pipe. A traction mechanism for quickly pulling the bottom end of the concrete delivery pipe to a pouring position is clamped inside the concrete delivery pipe. The outer surface of the traction mechanism abuts against the inner wall of the concrete delivery pipe. A limiting mechanism is provided inside the traction mechanism. The left and right sides of the limiting mechanism are respectively installed between the left and right inner walls of the traction mechanism.

[0008] Furthermore, the traction mechanism includes a fixed sleeve, the inner wall of the fixed sleeve is provided with a connecting block, electric telescopic rods are installed on the left and right sides of the connecting block, arc-shaped fixed plates are installed on the left and right output ends of the two groups of electric telescopic rods, the opposite sides of the two groups of arc-shaped fixed plates are abutted against the inner wall of the concrete conveying pipe, and base plates are installed on the opposite sides of the two groups of arc-shaped fixed plates. A control panel is provided on the upper surface of the base plate of the left group, and fixed rods are installed on the upper surfaces of the two groups of base plates. Handles are provided on the tops of the two groups of fixed rods, and the control panel and the control ends of the two groups of electric telescopic rods are electrically connected.

[0009] Furthermore, anti-slip bumps are provided on opposite sides of the two groups of arc-shaped fixing plates.

[0010] Furthermore, the outer contours of the two groups of electric telescopic rods are adapted to the inner contour of the fixing sleeve.

[0011] Furthermore, the limiting mechanism includes two groups of fixed blocks, both groups of fixed blocks have grooves inside, both groups of fixed blocks are installed on the upper surface of the fixed sleeve, the grooves of the two groups of fixed blocks are slidably connected to limiting rods, and the opposite ends of the two groups of limiting rods are respectively installed on the adjacent side of the two groups of arc-shaped fixed plates.

[0012] Furthermore, the outer surface of the electric telescopic rod is painted with anti-rust paint.

[0013] Furthermore, outer surfaces of the two groups of handles are sleeved with handle covers.

[0014] Furthermore, grooves are provided on opposite sides of the two groups of arc-shaped fixing plates, and pressure sensing strips are provided inside the grooves of the two groups of arc-shaped fixing plates. The two groups of pressure sensing strips are electrically connected to the control ends of the two groups of electric telescopic rods.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention moves the two sets of curved fixing plates by carrying and adjusting the positions of the two sets of curved fixing plates to the inside of the concrete conveying pipe, and then activates the two sets of electric telescopic rods by operating the control panel to push the two sets of curved fixing plates to move, so that the opposite sides of the two sets of curved fixing plates are both in contact with the inner wall of the concrete conveying pipe, so that the two sets of curved fixing plates are subsequently positioned and clamped on the inner wall of the concrete conveying pipe, and the two sets of handles are pulled to drive the two sets of curved fixing plates to pull the guide end of the concrete conveying pipe to move, thereby minimizing the possibility that the two sets of curved fixing plates will slip from the inside of the concrete conveying pipe when the concrete conveying pipe stops conveying concrete, thereby improving the stability of the subsequent traction mechanism during use.

The present invention has two sets of limit rods with opposite ends respectively installed on the adjacent side of the two sets of arc-shaped fixing plates, and then the two sets of limit rods are respectively slidably connected to the grooves of the two sets of fixing blocks, so that the subsequent two sets of fixing blocks and the two sets of limit rods limit the movement paths of the two sets of arc-shaped fixing plates on the left and right sides of the fixing sleeve, thereby minimizing the bending of the two sets of electric telescopic rods when the subsequent two sets of arc-shaped fixing plates are hit, thereby improving the service life of the subsequent traction mechanism.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0028] like Figures 1 to 5 As shown, a large-volume concrete pouring device for an ultra-deep foundation pit includes a concrete conveying pipe 1, the interior of the concrete conveying pipe 1 is clamped with a traction mechanism 2 for quickly pulling the bottom end of the concrete conveying pipe 1 to the pouring position, the outer surface of the traction mechanism 2 abuts the inner wall of the concrete conveying pipe 1, and a limiting mechanism 4 is provided inside the traction mechanism 2, and the left and right sides of the limiting mechanism 4 are respectively installed between the left and right inner walls of the traction mechanism 2; specifically, by starting the traction mechanism 2, the left and right outer surfaces of the traction mechanism 2 are clamped and positioned on the inner wall of the concrete conveying pipe 1, so that the subsequent traction mechanism 2 is installed in the interior and outer end of the concrete conveying pipe 1 in a clamping manner, thereby minimizing the possibility that the left and right sides of the traction mechanism 2 slip from the interior of the concrete conveying pipe 1 when the subsequent concrete conveying pipe 1 stops conveying concrete, causing the subsequent traction mechanism 2 to be unable to continuously pull the guide end of the concrete conveying pipe 1 to move, thereby improving the stability of the subsequent traction mechanism 2 during use.

[0029] like Figures 1 to 5 As shown, the traction mechanism 2 includes a fixed sleeve 202, an inner wall of the fixed sleeve 202 is provided with a connecting block 208, and electric telescopic rods 203 are installed on both sides of the connecting block 208. The left and right output ends of the two sets of electric telescopic rods 203 are installed with arc-shaped fixed plates 201, and the opposite sides of the two sets of arc-shaped fixed plates 201 are abutted against the inner wall of the concrete conveying pipe 1. The opposite sides of the two sets of arc-shaped fixed plates 201 are installed with base plates 204. A control panel 205 is provided on the upper surface of the left set of base plates 204, and fixed rods 206 are installed on the upper surfaces of the two sets of base plates 204. The tops of the two sets of fixed rods 206 are provided with handles 207. The control panel 205 is electrically connected to the control ends of the two sets of electric telescopic rods 203.

[0030] Specifically, the two sets of arc-shaped fixing plates 201 are moved and adjusted to the position of the two sets of arc-shaped fixing plates 201 to the inside of the concrete conveying pipe 1, and then the two sets of electric telescopic rods 203 are started by operating the control panel 205 to push the two sets of arc-shaped fixing plates 201 to move, so that the opposite sides of the two sets of arc-shaped fixing plates 201 are both against the inner wall of the concrete conveying pipe 1, so that the subsequent two sets of arc-shaped fixing plates 201 are positioned and clamped on the inner wall of the concrete conveying pipe 1, and the two sets of handles 207 are pulled to drive the two sets of arc-shaped fixing plates 201 to pull the guiding end of the concrete conveying pipe 1 to move, so as to avoid the two sets of arc-shaped fixing plates 201 from slipping from the inside of the concrete conveying pipe 1 when the subsequent concrete conveying pipe 1 stops conveying concrete, thereby improving the stability of the subsequent traction mechanism 2 during use.

[0031] like Figure 1 and Figure 3 As shown, anti-skid protrusions 3 are provided on opposite sides of the two groups of arc-shaped fixing plates 201; specifically, the anti-skid protrusions 3 are positioned between the contact surfaces of the two groups of arc-shaped fixing plates 201 and the inner wall of the concrete conveying pipe 1, so that the subsequent anti-skid protrusions 3 increase the friction between the contact surfaces of the two groups of arc-shaped fixing plates 201 and the inner wall of the concrete conveying pipe 1, thereby minimizing the sliding of the subsequent two groups of arc-shaped fixing plates 201 after being clamped inside the concrete conveying pipe 1, thereby improving the stability of the subsequent traction mechanism 2 during use.

[0032] like Figure 5 As shown, the outer contours of the two sets of electric telescopic rods 203 are adapted to the inner contour of the fixed sleeve 202; specifically, by adapting the outer contours of the two sets of electric telescopic rods 203 to the inner contour of the fixed sleeve 202, the subsequent two sets of electric telescopic rods 203 can block the interior of the groove of the fixed sleeve 202, thereby minimizing the possibility that concrete enters the interior of the groove of the fixed sleeve 202 when the subsequent traction mechanism 2 is installed inside the concrete conveying pipe 1, causing the subsequent two sets of electric telescopic rods 203 to be unable to move normally.

[0033] like Figure 4As shown, the limit mechanism 4 includes two sets of fixing blocks 401, and the interiors of the two sets of fixing blocks 401 are provided with grooves. The two sets of fixing blocks 401 are both mounted on the upper surface of the fixing sleeve 202. The interiors of the grooves of the two sets of fixing blocks 401 are slidably connected to the limit rods 402, and the opposite ends of the two sets of limit rods 402 are respectively mounted on the adjacent side of the two sets of curved fixing plates 201; specifically, the opposite ends of the two sets of limit rods 402 are respectively mounted on the adjacent side of the two sets of curved fixing plates 201, and then the two sets of limit rods 402 are respectively slidably connected to the interiors of the grooves of the two sets of fixing blocks 401, so that the subsequent two sets of fixing blocks 401 and the two sets of limit rods 402 limit the movement paths of the two sets of curved fixing plates 201 on the left and right sides of the fixing sleeve 202, thereby minimizing the bending of the two sets of electric telescopic rods 203 when the subsequent two sets of curved fixing plates 201 are hit, thereby improving the service life of the subsequent traction mechanism 2.

[0034] like Figure 5 As shown, the outer surface of the electric telescopic rod 203 is painted with anti-rust paint; specifically, by painting the outer surface of the electric telescopic rod 203 with anti-rust paint, the subsequent anti-rust paint wraps and protects the outer surface of the electric telescopic rod 203, thereby minimizing the subsequent corrosion of the electric telescopic rod 203 during long-term use inside the concrete conveying pipe 1, thereby improving the service life of the subsequent traction mechanism 2.

[0035] like Figures 1 to 3 As shown, the outer surfaces of the two sets of handles 207 are both sleeved with handle covers 5; specifically, the positions of the two sets of handle covers 5 are both set at the outer ends of the two sets of handles 207, so that the hands of subsequent staff are not easy to slip when holding the outer ends of the two sets of handles 207, thereby improving the stability of subsequent staff in the process of pushing the two sets of handles 207 to drive the guiding end of the concrete conveying pipe 1 to move.

[0036] like Figure 1 and Figure 3 As shown, grooves are provided on opposite sides of the two sets of arc-shaped fixing plates 201, and pressure sensing strips 6 are provided inside the grooves of the two sets of arc-shaped fixing plates 201. The two sets of pressure sensing strips 6 are electrically connected to the control ends of the two sets of electric telescopic rods 203. Specifically, the positions of the two sets of pressure sensing strips 6 are set between the contact surfaces of the two sets of arc-shaped fixing plates 201 and the inner wall of the concrete conveying pipe 1, so that when the opposite sides of the two sets of arc-shaped fixing plates 201 are subsequently abutted against the inner wall of the concrete conveying pipe 1, the two sets of pressure sensing strips 6 are triggered to shut down the two sets of electric telescopic rods 203, thereby avoiding as much as possible that the subsequent staff excessively adjusts and moves the positions of the two sets of arc-shaped fixing plates 201, which may cause the interior of the subsequent concrete conveying pipe 1 to be squeezed and ruptured, thereby improving the service life of the subsequent concrete conveying pipe 1.

[0037] In summary, by moving the two sets of arc-shaped fixing plates 201, the positions of the two sets of arc-shaped fixing plates 201 are adjusted and moved to the inside of the concrete delivery pipe 1, and then the two sets of electric telescopic rods 203 are activated by the control panel 205 to push the two sets of arc-shaped fixing plates 201 to move, so that the opposite sides of the two sets of arc-shaped fixing plates 201 are both against the inner wall of the concrete delivery pipe 1, so that the two sets of arc-shaped fixing plates 201 are subsequently positioned and clamped on the inner wall of the concrete delivery pipe 1, and by pulling the two sets of handles 207, the two sets of arc-shaped fixing plates 201 are driven to pull the guide end of the concrete delivery pipe 1 to move, thereby Try to avoid the two sets of arc-shaped fixed plates 201 sliding out of the interior of the concrete conveying pipe 1 when the concrete conveying pipe 1 stops conveying concrete; the positions of the two sets of pressure sensing strips 6 are set between the contact surfaces of the two sets of arc-shaped fixed plates 201 and the inner wall of the concrete conveying pipe 1, so that when the opposite sides of the two sets of arc-shaped fixed plates 201 abut against the inner wall of the concrete conveying pipe 1, the two sets of pressure sensing strips 6 are triggered to shut down the two sets of electric telescopic rods 203, thereby trying to avoid the subsequent staff from excessively adjusting the positions of the two sets of arc-shaped fixed plates 201, which may cause the interior of the concrete conveying pipe 1 to be squeezed and ruptured.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
