Background Technique

[0002] Generally speaking, concrete pumping technology is an indispensable part of modern construction. The concrete pump truck transports concrete to the construction site through high pressure, improving the construction efficiency and quality. However, during the pumping process, due to the complexity of the concrete flow characteristics and the influence of factors such as pumping pressure and speed, the problem of concrete splashing at the discharge port has become a common technical problem.

[0003] Concrete splashing has an impact on the surrounding environment and safety. Concrete splashing pollutes the surrounding enclosures and poses a safety hazard to pedestrians outside the enclosures, and it is difficult to meet the increasingly strict requirements of the construction environment, seriously affecting the cleanliness and hygiene of the construction site.

[0004] At present, although there are already related devices designed to prevent concrete splashing at the discharge port of the concrete pump truck in the existing technology, they all have complex structures, are inconvenient to install and disassemble, have poor anti-splashing effects on concrete, and at the same time, the protection device cannot be replaced or reused according to actual needs, resulting in waste of resources and inconvenient maintenance and replacement. In short, it is often very inconvenient.

[0005] Therefore, developing a simple protection device for preventing concrete from splashing at the discharge port of a concrete pump truck with a simple structure, high practicality and working reliability is the key to solving the above technical problems. Summary of the Invention

[0006] In view of the many defects and deficiencies in the above background technique, the utility model has made improvements and innovations. The purpose is to provide a protection device with novel design and simple structure. Using this protection device as the protection device for the discharge port of the concrete pump truck's conveying pipe can not only meet the concrete discharge requirements of various scenarios, but also prevent the problem of concrete splashing to the greatest extent, with simple operation, convenient and efficient.

[0007] To solve the above problems and achieve the above invention purpose, a simple protection device for preventing concrete from splashing at the discharge port of a concrete pump truck of the utility model is realized by adopting the following design structure and the following technical solutions:

It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and embodiments.

[0043] As Figures 1 to 8 shown, a simple protective device for preventing splashing at the discharge port of a concrete pump truck includes:

[0044] A protective cover body 1, and the protective cover body 1 is rotatably installed at the discharge port 51 of the material conveying pipe of the concrete pump truck 5 through a connecting piece 2;

[0045] The retractable protective baffle 3 is detachably mounted on the protective cover body 1 and is used to prevent concrete splashing.

[0046] In the utility model, the connecting member 2 is a connecting shaft or a bolt assembly.

[0047] Furthermore, as Figure 7 shown, mounting columns 11 are symmetrically connected to the outer wall of the lower end of the protective cover body 1. The mounting columns 11 are used to mount the retractable protective baffle 3.

[0048] In the present utility model, the mounting columns 11 are connected to the outer wall of the lower end of the protective cover body 1.

[0049] Specifically, as Figure 7 shown, mounting holes 12 for allowing the connecting member 2 to pass through are symmetrically formed on both sides of the protective cover body 1. The mounting holes 12 penetrate through the front and back sides of the side wall of the protective cover body 1.

[0050] Furthermore, as Figure 7 shown, annular lifting lugs 13 are symmetrically connected to the outer wall of the upper end of the protective cover body 1. The lifting lugs 13 are used to connect a pulling rope 14.

[0051] In the present utility model, the pulling rope 14 is a steel wire rope or a chain or a limiting rope, and is used to adjust the position of the protective cover body 1.

[0052] Specifically, the protective cover body 1 is formed by enclosing an arc-shaped baffle and a cover plate connected to the top of the arc-shaped baffle.

[0053] Specifically, as Figure 8 shown, long-shaped adjustment holes 31 corresponding to the mounting columns 11 are symmetrically formed on both sides of the retractable protective baffle 3. The retractable protective baffle 3 is sleeved on the mounting columns 11, and the end part is fastened by an anti-detaching limiting member 4 so as to be integrally connected with the protective cover body 1.

[0054] More specifically, as Figure 8 shown, the retractable protective baffle 3 is an arc-shaped plate-like member as a whole in the shape of "C", "semicircular", "semi-horn-shaped" or "semi-truncated cone-shaped".

[0055] In summary, a more specific embodiment of the present utility model is:

[0056] Before the above-described simple protective device for preventing splashing at the discharge port of a concrete pump truck with the above design structure is used, the already fabricated protective device needs to be installed for standby.

[0057] During installation, the construction workers only need to detachably install the protective cover body 1 of the present utility model at the discharge port 51 of the delivery pipe of the concrete pump truck 5 by using the connecting member 2. Then, according to the specific construction, the operator adjusts the retractable protective baffle 3. After adjusting the retractable protective baffle 3 to a suitable length position, the operator fixes the retractable protective baffle 3 at a suitable position on the protective cover body 1 through the anti-detachment limiting member 4 and connects them into an integral structure, so as to meet the actual needs in construction. After the installation is stable and reliable, the concrete pouring work can be carried out.

[0058] Before work, the construction workers pass two pull ropes 14 through the two lifting lugs 13 respectively. At the same time, the height angle and position of the protective cover body 1 are adjusted by adjusting the tightness of the two pull ropes 14. After the adjustment is completed, the pull ropes 14 are connected and fixed to the concrete pump truck 5. After the connection is stable and reliable, the work can be carried out.

[0059] During work, since the protective device of the present utility model is installed at the discharge port 51 of the delivery pipe of the concrete pump truck 5, when the concrete pump truck 5 is started to work, during the work process, the concrete can fall along the discharge port 51 of the delivery pipe to the position to be poured or fall into the concrete receiving device 6, achieving a certain degree of blocking of the concrete splash and largely eliminating the problem of concrete splashing around.

[0060] At the same time, after long-term work use, when there is a lot of concrete on the safety protection component body, the construction workers only need to turn off the concrete pump truck 5 to suspend work and clean the retractable protective baffle 3 and the protective cover body 1. If the cleaning is difficult, the construction workers can loosen the anti-detachment limiting member 4, remove the retractable protective baffle 3 and the protective cover body 1, and then clean them. After cleaning, turn on the concrete pump truck 5 to continue work, and cycle the above operations in sequence until the entire construction work is completed.

[0061] During the above entire implementation operation process, each component needs to be inspected. If the connecting member 2, the retractable protective baffle 3, or the anti-detachment limiting member 4 becomes loose during the inspection, the construction workers need to tighten or replace and repair them in time.

[0062] Finally, as time goes by, when all the construction work is completed, the construction workers only need to remove the present utility model as needed, clean and repair its various components, and then carry it to the designated tool storage room for placement and storage for use in the next cycle.

[0063] Finally, it should be noted that the specific implementation manners of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above implementation manners, and various changes can be made within the scope of knowledge possessed by those of ordinary skill in the art.
