Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring construction, in particular to a concrete pump pipe fixing structure for super high-rise building construction. Background Art

[0002] During the concrete pouring construction of super high-rise buildings, in order to prevent the outlet end of the concrete pump pipe from being pushed back due to vibration and falling from the floor rope, the outlet end of the concrete pump pipe is generally fixed directly to the wall.

[0003] However, when in use, if the outlet pipe reserved for the concrete pump pipe is relatively short, the outflowing concrete will always fall in the same area, and construction workers will need to use a small truck to transport the concrete to a distant construction area, which is inconvenient to use.

[0004] If the reserved concrete pump outlet pipe is relatively long, although the concrete discharge area can be changed by manually dragging the concrete pump outlet pipe, due to the heavy weight of the concrete pump plus the concrete in the pump pipe, and the friction between the concrete pump pipe and the ground, it is very laborious to manually drag the concrete pump outlet pipe.

[0005] In order to solve the above problems, the method commonly used in construction is to weld a pump pipe clamp on a trolley as a mobile platform for the outlet pipe of the concrete pump pipe, put the outlet pipe of the concrete pump pipe on the trolley, and fix the outlet end of the outlet pipe with the pump pipe clamp. When in use, the construction personnel push the trolley to change the outlet position of the outlet pipe.

[0006] However, the use of a trolley and a pump pipe clamp as a mobile platform for the outlet pipe of the concrete pump pipe still has the following problems: the outlet pipe of the concrete pump pipe is relatively long due to the length of the outlet pipe passing through the pump pipe clamp, resulting in the outlet pipe being suspended after passing through the pump pipe clamp. Since the concrete pump pipe will vibrate when conveying concrete, the suspended pipe phenomenon will further increase the vibration amplitude of the concrete pump pipe, which will make the pump pipe clamp easily loose, causing the concrete pump pipe to fall off the trolley, affecting the smooth progress of the concrete pouring construction. Summary of the invention

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1: A concrete pump pipe fixing structure for super high-rise building construction, such as Figure 1 As shown, it includes a base plate 1 and a roller mechanism arranged at the bottom of the base plate 1. The base plate 1 can be moved on the ground through the roller mechanism. A push handle 4 for pushing the base plate 1 to move forward and backward is welded to the front of the base plate 1.

[0049] In order to expand the contact area between the roller mechanism and the ground and reduce the pressure caused by the device on the ground or building surface when in use, the roller mechanism in this embodiment adopts a roller track mechanism. Specifically, Figure 1 and Figure 3 As shown, the roller mechanism in this embodiment includes three T-shaped rods arranged at a front-to-back interval at the bottom of the base plate 1, and rotatable rollers 2 are provided at both left and right ends of the T-shaped rods, and a track 3 is wound around the roller 2 on the same side.

[0050] like Figure 1As shown, two supporting structures extending in the up-down direction are rotatably provided on the bottom plate 1 in this embodiment. For the sake of easy identification, the rear supporting structure is set as the first supporting structure 6, and the front supporting structure is set as the second supporting structure 7. The first supporting structure 6 and the second supporting structure 7 have the same structure and connection structure with the bottom plate 1.

[0051] Taking the structure of the first supporting structure 6 as an example, Figure 2 As shown, the first supporting structure 6 includes a turntable 9 and a bottom cover 8 with a buckle cover structure having a lower opening.

[0052] A rotating hole which is transparent from top to bottom is opened on the top of the bottom cover 8 , and the bottom of the bottom cover 8 is welded to the upper surface of the bottom plate 1 .

[0053] like Figure 6 As shown, the turntable 9 includes a turntable 901 rotatably arranged in the bottom cover 8 and a support column fixed on the turntable 901, the upper end of the support column passes through the turntable hole at the top of the bottom cover 8, the diameter of the turntable 901 is larger than the inner diameter of the turntable hole, and the turntable 901 cooperates with the bottom cover 8 to form an anti-falling structure to prevent the turntable 9 from falling off the bottom cover 8.

[0054] In order to limit the rotation of the turntable 9 when the device starts working, so as to avoid the vibration of the concrete pump pipe driving the turntable 9 to rotate, thereby causing the outlet direction of the concrete to change uncontrolled by the construction personnel, such as Figure 6 and Figure 7 As shown, in this embodiment, limiting teeth 902 of a tooth structure are provided on the side surface of the rotating disk 901 at equal intervals along the circumferential direction.

[0055] A transparent slot is provided on the side surface of the bottom cover 8, and a stopper mechanism capable of moving left and right is inserted into the slot.

[0056] The stopping mechanism comprises an arc-shaped clamping plate 22 and an inserting rod 23 . Stopping teeth capable of engaging with the limiting teeth 902 are arranged at intervals on one side of the arc-shaped clamping plate 22 facing the rotating disk 901 .

[0057] The side of the arc-shaped clamping plate 22 away from the rotating disk 901 is welded to one end of the insertion rod 23 , the insertion rod 23 is inserted into a slot on the side of the bottom cover 8 , and the end of the insertion rod 23 away from the rotating disk 901 extends to the outside of the bottom cover 8 .

[0058] The stopping tooth can be disengaged from the limiting tooth 902 as the stopping mechanism moves toward the outside of the bottom cover 8 , so that the rotating disk 901 can rotate under the action of an external force.

[0059] like Figure 7As shown, a vertical plate 24 is fixedly provided at one end of the insertion rod 23 away from the rotating disk 901, a positioning ring 25 is welded to the side of the plate 24 away from the bottom cover 8, and a vertical positioning rod 26 is inserted in the positioning ring 25. In order to facilitate the application of force when pulling out the positioning rod 26, the positioning rod 26 in this embodiment is an L-shaped rod structure.

[0060] The bottom plate 1 is provided with a positioning groove 102 with an upper opening. When the lower end of the positioning rod 26 is inserted into the positioning groove 102, the stop teeth on the arc-shaped clamping plate 22 mesh with the limit teeth 902. This prevents the stop teeth from accidentally disengaging from the limit teeth 902 when the device starts working, causing the turntable 9 to start rotating under the vibration of the concrete pump pipe, thereby affecting the concrete pouring effect.

[0061] In order to enable the insertion rod 23 to automatically move away from the bottom cover 8 after the positioning rod 26 is pulled out, so as to realize the automatic disengagement of the stop tooth and the limit tooth 902, and to avoid the trouble of manually pushing the insertion rod 23 to move, and to prevent the arc-shaped clamping plate 22 from accidentally resetting when the turntable 9 is rotated, so as to cause the stop tooth and the limit tooth 902 to mesh again, resulting in the turntable 9 being stuck. In this embodiment, opposite protruding rods are provided on the side plates of the pull plate 24 and the bottom cover 8, and a spring 27 is sleeved on the two protruding rods.

[0062] When the lower end of the positioning rod 26 passes through the positioning ring 25 and is inserted into the positioning groove 102, the spring 27 is in a compressed state. When the positioning rod 26 is pulled out, the compressed spring 27 drives the insertion rod 23 to drive the arc-shaped clamping plate 22 to automatically move away from the bottom cover 8, so that the stop tooth and the limit tooth 902 are automatically separated.

[0063] For example, in order to reduce the friction between the bottom of the turntable 901 and the upper surface of the bottom plate 1 when the turntable 9 rotates and reduce the thrust required to rotate the turntable 9, two inner and outer annular grooves 101 corresponding to the upper and lower sides of the turntable 901 and open on the top are opened on the bottom plate 1. A ball 21 is placed in the annular groove 101. The top of the ball 21 protrudes from the upper surface of the bottom plate 1, and the top of the ball 21 is in rolling contact with the bottom of the turntable 901.

[0064] like Figure 2 As shown, a handle 10 for driving the turntable 9 to rotate is fixedly provided on the top of the turntable 9.

[0065] like Figure 2 As shown, a vertical lifting rod mechanism is fixedly provided on the top of the turntable 9, through which the height of the outlet end of the concrete pump pipe is adjusted, in coordination with the lift of the concrete column discharged from the outlet end of the concrete pump pipe, the distance adjustment of the pouring range during concrete pouring is realized, and in coordination with the rotation of the turntable 9, the direction of the outlet end of the concrete pump pipe is adjusted to achieve the purpose of moving the device as little as possible during use, and to minimize the impact of moving the device on the surface of the freshly poured concrete.

[0066] In order to realize the lifting and lowering of the lifting rod mechanism to form an easy-to-control structure and reduce the accessories required for the lifting rod mechanism as much as possible to reduce the weight of the device, such as Figure 1 and Figure 2 As shown, the lifting rod mechanism is an electric telescopic rod 11, and the bottom of the cylinder of the electric telescopic rod 11 is fixedly connected to the top of the turntable 9. A power box 5 for supplying power to the electric telescopic rod 11 and lifting the electric telescopic rod 11 is provided on the bottom plate 1, and the power box 5 is electrically connected to the electric telescopic rod 11.

[0067] A clamping mechanism is provided at the top of the piston rod of the electric telescopic rod 11. The middle part of the clamping mechanism forms an annular channel for placing the concrete pump pipe, and the clamping mechanism is used to clamp the outlet end of the concrete pump pipe and make the outlet end of the concrete pump pipe parallel to the bottom plate 1.

[0068] Specifically, Figure 2 As shown, the clamping mechanism includes a limiting seat 12 and a clamping seat 13 arranged on the top of the limiting seat 12.

[0069] The limiting seat 12 is provided with an arc-shaped groove I with an upper opening, and horizontal ear plates I are provided on the left and right sides of the limiting seat 12, and screw holes I that are transparent from top to bottom are provided on the ear plates I.

[0070] The clamp seat 13 is provided with an arc-shaped groove II with a lower opening, and the arc-shaped groove II corresponds to the arc-shaped groove I in upper and lower directions. The left and right sides of the clamp seat 13 are provided with horizontal ear plates II, and the ear plates II are provided with screw holes II corresponding to the screw holes I in upper and lower directions. Bolts are passed through the screw holes I and II, and the bolts are used to adjust the distance between the arc-shaped groove I and the arc-shaped groove II.

[0071] like Figure 4 As shown, in order to stabilize the stability of the outlet end of the concrete pump pipe extending out of the clamping mechanism when in use, reduce the vibration amplitude of the outlet end of the concrete pump pipe when in use, and also to provide a certain stopping effect on the outlet end of the concrete pump pipe to reduce the stopping pressure of the clamping mechanism on the concrete pump pipe (the excessive vibration amplitude of the concrete pump pipe when in use greatly reduces the time for the bolts of the clamping mechanism to loosen), this embodiment is provided with a locking mechanism 15 in the annular direction at the front of the limit seat 12 and the clamping seat 13, and the front end of the locking mechanism 15 is provided with a locking mouth for supporting the concrete pump pipe, and the locking mouth can be opened and closed and reset by itself.

[0072] Specifically, the locking mechanism 15 includes a plurality of spring rod mechanisms arranged at intervals in an annular manner. Figure 5 As shown, the spring rod mechanism includes an axle seat 16, which is a hollow box structure with an opening at the front, and the rear portion of the axle seat 16 is welded to the front portion of the clamping mechanism.

[0073] The rear end of the connecting rod 17 is inserted into the axle seat 16, and two symmetrical connecting shafts 19 are fixedly provided at the rear of the connecting rod 17. The connecting shafts 19 and the connecting rod 17 are perpendicular to each other. The end of the connecting shaft 19 away from the connecting rod 17 is passed through the side plate of the axle seat 16, and the connecting shaft 19 is rotatably connected to the side plate of the axle seat 16.

[0074] A spring reset mechanism is provided on the shaft seat 16 for resetting the connecting rod 17 after rotation. When the spring reset mechanism is in an initial state, the front ends of all the connecting rods 17 are inclined toward the axial direction of the annular channel to form the locking opening.

[0075] Specifically, in this embodiment, in order to balance the force applied by the spring reset mechanism to the connecting rod 17 when the connecting rod 17 is reset, the spring reset mechanism in this embodiment adopts a torsion spring 20 respectively sleeved on the two connecting shafts 19. One end of the torsion spring 20 is fixedly connected to the connecting rod 17, and the other end of the torsion spring 20 is fixedly connected to the inner wall of the shaft seat 16.

[0076] When the concrete pump pipe passes through the locking mechanism 15, the front end of the connecting rod 17 rotates outward to expand at the same time. At this time, the torsion spring 20 is in a contracted state, so that the front end of the connecting rod 17 is tightly pressed against the pipe wall near the outlet end of the concrete pump pipe, providing a certain supporting force for the outlet end of the concrete pump pipe, avoiding the outlet end of the concrete pump pipe from being suspended in the air, and reducing the vibration amplitude of the outlet end of the concrete pump pipe due to suspension during vibration.

[0077] At the same time, the inclined connecting rod 17 can also provide a certain stopping force for the outlet end of the concrete pump pipe.

[0078] In order to prevent the edges and corners of the front end of the connecting rod 17 from scratching the wall of the concrete pump pipe, a steel ball 18 is welded to the front end of the connecting rod 17 in this embodiment.

[0079] Example 2: A concrete pump pipe fixing structure for super high-rise building construction. The difference between this example and Example 1 is that the spring reset mechanism uses a vertically arranged tension spring to achieve the reset of the connecting rod 17, the lower end of the tension spring is fixedly connected to the connecting rod 17, and the upper end of the tension spring is fixedly connected to the top plate of the shaft seat 16.

[0080] When the concrete pump pipe passes through the locking mechanism 15, the front end of the connecting rod 17 rotates outward to expand the locking opening, and the tension spring is in a tensioned state.

[0081] Embodiment 3: A concrete pump pipe fixing structure for super high-rise building construction, the difference between this embodiment and embodiment 1 is that the annular groove 101 is no longer provided on the bottom plate 1, and the ball bearing 21 is no longer provided on the bottom plate 1. The bottom of the turntable 901 is in sliding contact with the upper surface of the bottom plate 1. The other structures are the same as those of embodiment 1.

[0082] Embodiment 4: A concrete pump pipe fixing structure for super high-rise building construction, the difference between this embodiment and embodiment 1 is that the lifting rod mechanism in this embodiment adopts a hydraulic cylinder, and a hydraulic control box for controlling the lifting of the hydraulic cylinder is arranged on the bottom plate 1. The other structures are the same as those in embodiment 1.

The other structures are the same as those in embodiment 1.

[0084] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is limited by the appended claims rather than the above description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
