Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a shock-absorbing movable bracket for a large-volume concrete pouring pump pipe. Background Technique

[0002] At the present stage, during the construction of large-volume concrete pouring, due to the inconvenient arrangement of concrete mixer trucks in some construction areas, it is necessary to add a concrete pouring pump pipe structure. In actual construction, in areas with a relatively high pouring position, due to the large pumping height, the pump pipe is prone to large vibrations during the pumping process, which may lead to problems such as loosening and disconnection of the pump pipe at unstable connection positions, affecting the concrete pouring construction. Especially for large-volume concrete pouring construction, this problem is more obvious.

[0003] In the prior art, during the concrete pouring operation at most construction sites, the operators usually directly lay the horizontal concrete pump pipe on the ground and pad it with materials such as square timbers or waste tires at the bottom to avoid wearing the outer wall of the concrete pump pipe. However, due to the relatively large vibrations generated by the pump pipe during the concrete pouring operation, the shock-absorbing effect of the traditional pump pipe erection method is limited, and there will also be a certain degree of wear on the outer wall of the pump pipe. If the outer wall of the pump pipe is severely worn, it cannot meet the safety requirements of the concrete pouring construction site; once the pipeline bursts, it is not conducive to construction safety and even less conducive to the continuous pouring of concrete, and it will also have an adverse impact on the forming quality of the concrete on the working surface.

When the number of the supporting legs 2 is two, a supporting leg can be arranged on the outer periphery of the supporting leg 2 to ensure stability. The shock-absorbing assembly 3 is used to achieve shock absorption of the pump pipe. Since there may be more than one pump pipe at the same location, the shock-absorbing assembly 3 on one base 1 is at least one. When the shock-absorbing assemblies 3 are two or more, the shock-absorbing assemblies 3 are arranged at intervals along the length direction of the base 1; the support column 4 can be fixed on the base 1 by bolts, the shock-absorbing spring 5 is coaxially and fixedly connected with the support column 4, and the shock-absorbing spring 5 is used to reduce the vibration transmitted to the support column 4 by the pump pipe during concrete pumping. The fixing ring 6 is fixedly connected with the shock-absorbing spring 5, and the fixing ring 6 is used to fix the pump pipe.

[0026] In order to improve the adaptability of the bracket, further, refer to Figure 1 , a T-shaped groove 7 is arranged on the upper surface of the base 1, a connecting disc 8 is rotatably arranged in the T-shaped groove 7, the shock-absorbing assembly 3 is fixedly connected with the upper surface of the connecting disc 8, and a locking assembly 9 is arranged between the connecting disc 8 and the T-shaped groove 7. The width of the notch of the T-shaped groove 7 is smaller than the diameter of the connecting disc 8; the width of the bottom of the T-shaped groove 7 is larger than the diameter of the connecting disc 8. For example, the width of the bottom of the T-shaped groove 7 is 105 mm, and the diameter of the connecting disc 8 is 100 mm; the height of the T-shaped groove 7 is larger than the thickness of the connecting disc 8. For example, the height of the T-shaped groove 7 is 22 mm, and the thickness of the connecting disc 8 is 20 mm; in this way, the connecting disc 8 can rotate in the T-shaped groove 7, and at the same time, the T-shaped groove 7 can also realize the axial limit of the connecting disc 8. When the connecting disc 8 rotates to a suitable position, the locking assembly 9 is used to limit the connecting disc 8.

[0027] Embodiment 1 of the locking assembly 9, refer to Figure 3 , the locking assembly 9 includes a plurality of first through holes 10 arranged on the connecting disc 8, the plurality of first through holes 10 are arranged along the circumferential direction of the connecting disc 8, a second through hole 11 matched with the first through hole 10 is arranged on the bottom wall of the T-shaped groove 7, and the first through hole 10 and the second through hole 11 are connected by a pin shaft 12. In order to facilitate the insertion and extraction of the pin shaft 12, a handle 13 is arranged at the top end of the pin shaft 12. The first through holes 10 and the second through holes 11 can be arranged at intervals of 30°, and each second through hole 11 is opposite to a first through hole 10.

The threaded holes 14 can be arranged at an interval of 30°. When the connecting disc 8 rotates to a proper position, the locking bolt 15 is screwed into one of the threaded holes 14 until the end of the locking bolt 15 abuts against the bottom wall of the T-shaped groove 7, so as to realize the locking of the connecting disc 8; it should also be noted here that when using the locking bolt 15 to lock the connecting disc 8, when adjusting the position of the connecting disc 8, the connecting disc 8 can also be moved along the extending direction of the T-shaped groove 7, and the adaptability is stronger.

[0029] In the above embodiment, the fixing ring 6 is a whole ring. Only when laying the pipes, the end of the pump pipe is sequentially passed through the fixing ring 6 to arrange the pump pipe. It is not convenient to place the pump pipe that has already started working on the bracket. Further, refer to Figure 6 , the fixing ring 6 includes an upper semi-circular ring 16 and a lower semi-circular ring 17. The lower surface of the lower semi-circular ring 17 is fixedly connected to the top end of the shock-absorbing spring 5. The upper semi-circular ring 16 and the lower semi-circular ring 17 are connected by bolts. By setting the fixing ring 6 as a split upper semi-circular ring 16 and a lower semi-circular ring 17, the upper semi-circular ring 16 and the lower semi-circular ring 17 are coaxial; when installing the pump pipe, first place the pump pipe in the groove of the lower semi-circular ring 17, then buckle the upper semi-circular ring 16 on the lower semi-circular ring 17, and finally connect the upper semi-circular ring 16 and the lower semi-circular ring 17 with bolts, so as to realize the arrangement of the pump pipe.

[0030] As a preferred implementation manner, refer to Figure 6The upper semicircular ring 16 is provided with first connecting ears 18 at both ends along the radial direction, and the first connecting ears 18 are provided with a first connecting hole.

The axes of the first threaded rod 20 and the second threaded rod 21 are parallel, and the spacing between the axes of the first threaded rod 20 and the second threaded rod 21 is the same as the spacing between the axes of the first connecting hole and the second connecting hole, so that when the first threaded rod 20 is placed in the first connecting hole, the second threaded rod 21 can also be placed in the second connecting hole, and finally, the nut 22 is screwed on the first threaded rod 20 and the second threaded rod 21 to realize the connection between the upper semicircular ring 16 and the lower semicircular ring 17.

[0031] To further reduce vibration, see Figure 6 Shock-absorbing pads 29 are arranged on the inner walls of the upper semicircular ring 16 and the lower semicircular ring 17. The shock-absorbing pads 29 can be sponge pads, which can reduce the vibration transmitted by the pump pipe and protect the outer wall of the pump pipe from wear.

[0032] For easy transportation and storage, see Figure 1 , Figure 2 and Figure 4 , there are four legs 2, and they are opposite to each other. The legs 2 are connected to the base 1 through a hinge seat 24. The outer side of the legs 2 is provided with a baffle 25 for limiting the rotation of the legs 2. Taking two vertically opposite legs 2 as an example, the two legs 2 have four opposite and parallel faces in total, the two closest faces are the inner side faces, and the two farthest faces are the outer side faces. The outer side of the leg 2 is the side of the leg 2 away from its inner side face. The baffle 25 and the base 1 can be bolted. The leg 2 is placed vertically when in use and placed horizontally when not in use. The baffle 25 can limit the leg 2 from continuing to rotate after it is rotated to the vertical position.

[0033] In order to ensure the stability of the legs 2 after they are opened, see Figure 1 ,Figure 2 and Figure 4 On the inner side of each leg 2, a sleeve 26 is vertically arranged, and a plug rod 27 is arranged inside the sleeve 26. The tops of two opposite plug rods 27 are fixedly connected by a connecting rod 28. When the leg 2 is in the vertical state, the plug rods 27 at both ends of the connecting rod 28 are inserted into the sleeve 26. In this way, under the action of the connecting rod 28, the inward rotation of the leg 2 can be restricted, ensuring the stability of the leg 2.
