[0002] A concrete pump is a device used to transport concrete, usually used in construction sites and infrastructure construction. It is mainly composed of a mixer truck, a delivery pump, a delivery pipeline and accessories. The concrete pump delivers concrete from the mixer truck to the construction site through the delivery pump, which can achieve long-distance and high-efficiency concrete delivery, greatly improving construction efficiency and quality.

[0003] At present, when pouring concrete, concrete pumps are usually placed outdoors on temporary roads or municipal roads. Because concrete pouring is usually arranged at night, and concrete pumps make a lot of noise when working, and most construction sites are close to residential areas, it is easy to disturb residents when pouring concrete. Therefore, it is particularly important to reduce the noise of concrete pumps and ensure that construction does not disturb residents.

However, it still has the following problems in actual use:

[0005] 1. The above-mentioned noise reduction shed only has a single layer of sound-absorbing cotton as a sound-absorbing and noise-reducing structure. If it is used for the noise reduction work of large concrete pumps in large construction sites, it may not be able to complete the required noise reduction work well;

[0006] 2. If used for noise reduction of large concrete pumps in large construction sites, when enclosing the large concrete pumps, each side of the sound-absorbing enclosure structure needs to be connected to each other by multiple noise reduction sheds, and the noise reduction sheds can only be connected to each other by tying or other methods, which is inconvenient to use.

[0026] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example: Please refer to Figures 1 to 6The present embodiment provides a movable and hoistable concrete pump noise reduction shed, including an outer frame 1, the outer frame 1 is arranged in a rectangular frame structure, and the outer frame 1 is made of square steel material. The inner frame part of the outer frame 1 is provided with a sound-absorbing and noise-reducing component 2, and the sound-absorbing and noise-reducing component 2 is arranged in the form of filling the inner frame part of the outer frame 1. The sound-absorbing and noise-reducing component 2 includes a first protective layer 21, a first sound insulation layer 22, a vacuum panel 23, a second sound insulation layer 24, and a second protective layer 25 arranged in sequence from front to back. The first protective layer 21, the first sound insulation layer 22, the vacuum panel 23, the second sound insulation layer 24, and the second protective layer 25 are glued together in pairs according to the corresponding arrangement order, that is, the first sound insulation layer 22 is glued together with the first protective layer 21 and the vacuum panel 23 respectively, and the second sound insulation layer 24 is glued together with the vacuum panel 23 and the second protective layer 25 respectively.

[0028] In this embodiment, the first protective layer 21 and the second protective layer 25 are both common plastic protective plates in the prior art, which are impact-resistant and corrosion-resistant, and can protect the first sound insulation layer 22, the vacuum layer, and the second sound insulation layer 24 inside from being damaged by construction materials, so as to ensure the sound absorption and noise reduction capabilities of the sound-absorbing and noise-reducing component 2. The first sound insulation layer 22 and the second sound insulation layer 24 are both sound-absorbing rock wool boards in the prior art, which have excellent sound absorption performance. With the double-layer sound absorption structure, the sound absorption and noise reduction component 2 can be well applied even in the noise reduction work of large concrete floor pumps, and has the advantage of good noise reduction effect. At the same time, the sound-absorbing rock wool board also has the characteristics of being lightweight, so as to reduce the overall weight of the sound absorption and noise reduction component 2, so as to facilitate the subsequent transportation of the noise reduction shed.

[0029] The vacuum plate 23 is used to provide the required plate support for the sound-absorbing and noise-reducing component 2. To further improve the noise reduction effect of the sound-absorbing and noise-reducing component 2, in this embodiment, the vacuum plate 23 includes a first support layer 231 and a second support layer 232. The first support layer 231 and the second support layer 232 are both steel plates in the prior art, so as to provide the required plate support for the sound-absorbing and noise-reducing component 2, so that the sound-absorbing and noise-reducing component 2 has the required structural strength. A gap is left between the first support layer 231 and the second support layer 232, and the gap is filled with glass fiber 233. The filling of glass fiber 233 can keep a certain vacuum state in the gap, so that sound is difficult to propagate, thereby further improving the noise reduction effect of the sound-absorbing and noise-reducing component 2.

[0030] The working principle of the utility model is that when the noise reduction shed is in use, by surrounding the concrete pump, the noise can be effectively reduced, the problem of noise nuisance to the public can be solved, and green construction can be achieved.

[0031] To facilitate the use of the noise reduction shed, universal wheels 3 are provided at the bottom of the outer frame 1, which makes it easy for construction workers to move the outer frame 1. Lifting ears 4 are provided at the top of the outer frame 1, which makes it easy for construction workers to lift the outer frame 1.

[0032] In order to make the noise reduction shed suitable for the noise reduction work of large concrete floor pumps, a threaded hole 5 is opened on one side wall of the outer frame 1, and a connecting bolt 6 is movably connected to the other side wall. The positions of the connecting bolt 6 and the threaded hole 5 are adapted to each other so that when adjacent outer frames 1 are connected, the connecting bolt 6 on one outer frame 1 can be connected to the threaded hole 5 on another outer frame 1. A driving component for driving the connecting bolt 6 to rotate is also provided in the outer frame 1.

[0033] The driving assembly includes a first bevel gear 7 and a second bevel gear 8, which are both movably arranged inside the outer frame 1. A cavity can be provided inside the outer frame 1 to place the first bevel gear 7 and the second bevel gear 8, so as to meet the requirement of the movably arranged first bevel gear 7 and the second bevel gear 8. The connecting bolt 6 is arranged with one end movably inserted into the outer frame 1 and the other end extending out of the outer frame 1. The first bevel gear 7 is fixedly connected to the insertion end of the connecting bolt 6. The connection between the first bevel gear 7 and the connecting bolt 6 can be achieved by a key connection commonly used in the prior art. The second bevel gear 8 is meshedly connected to the first bevel gear 7. A driving rod 9 is fixedly connected to the second bevel gear 8. The connection between the second bevel gear 8 and the driving rod 9 can be achieved by a key connection commonly used in the prior art. The driving rod 9 movably extends outward from the front side wall of the outer frame 1.

[0034] Through the above-mentioned arrangement, when enclosing a large concrete floor pump, by placing adjacent outer frames 1 together, aligning the connecting bolt 6 on one of the outer frames 1 with the threaded hole 5 on the other outer frame 1, and then rotating the driving rod 9, the driving rod 9 drives the second bevel gear 8 to rotate, so as to drive the first bevel gear 7 to rotate, thereby driving the connecting bolt 6 to rotate. When the connecting bolt 6 rotates, the outer frame 1 is moved to move the connecting bolt 6 in a direction close to the threaded hole 5, so that the connecting bolt 6 can be connected to the threaded hole 5. The rotation of the connecting bolt 6 is maintained during the movement. After the connecting bolt 6 is screwed into the threaded hole 5 to connect the adjacent outer frames 1 together, the movement of the outer frame 1 and the rotation of the connecting bolt 6 are stopped. At this time, the connection of the adjacent outer frames 1 is realized, so that the noise reduction shed can form the required noise reduction shed group. Compared with the prior art, there is no need to use tying and the like, and it has the advantages of fast connection and easy use.

[0035] To facilitate the staff to rotate the drive rod 9, a special-shaped hole 10 is opened on the end of the drive rod 9 passing through the outer frame 1. In the present embodiment, the special-shaped hole 10 is a regular hexagonal hole, and the special-shaped hole 10 is matched with a rotating handle 11. The end of the rotating handle 11 close to the special-shaped hole 10 is adapted to the shape of the special-shaped hole 10. The rotating handle 11 is inserted into the special-shaped hole 10 through the end here, and the drive rod 9 can be driven to rotate by its own rotation, so as to facilitate the use of the staff. When there is no need to rotate the drive rod 9, the staff can remove the rotating handle 11 from the drive rod 9 for storage.

[0036] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
