Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a support beam crushing machine. Background Art

[0002] Support beams are a common building structure, mainly used to give buildings strong support to ensure the stability and safety of their structures. After the building is completed, no additional support is needed, and the original support beams generally need to be removed.

[0003] In the prior art, there are two common methods for dismantling support beams: one is to use an excavator to crush and dismantle them on site. This method is very noisy and can easily affect the lives of surrounding residents and lead to complaints. It also generates a large amount of dust, affecting the air quality. The other is to use a cutting machine to cut the support beams into sections and then transport them to a special site for crushing. This method has high processing costs and is more cumbersome to operate, so it needs to be improved. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a support beam crushing machine.

[0006] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0007] 1. Since the support beams are removed by crushing, the removal work can be carried out on the spot without the need for a transfer site, which is more convenient;

[0008] 2. The whole crushing process has low noise, does not disturb people, and can be constructed at night;

[0009] 3. The dust suppression mechanism can be used to suppress dust during the crushing process, so it is not easy to cause dust diffusion, dust generation, and is more environmentally friendly;

[0010] 4. The device has a simple structure, is easy to operate and has strong practicality.

[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and 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, and therefore cannot be understood as a limitation on the present invention.

[0019] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1 and Figure 2 A support beam 7 crusher shown in the figure comprises: a bracket 1, a telescopic member, a clamping plate 3 and a dust reduction mechanism. The bracket 1 is used to be connected to a tower crane, and a telescopic member is arranged on the bracket 1 in parallel on the left and the right, and the telescopic member can be horizontally extended and retracted, and a clamping plate 3 is respectively arranged on one side of the two telescopic members close to each other, and a convex tooth 4 is respectively arranged on one side of the two clamping plates 3 close to each other, and the dust reduction mechanism is located above the bracket 1 and connected to the bracket 1.

[0021] In specific applications, such as Figure 2 As shown, a lifting ring is provided on the bracket 1, which can be connected to a tower crane on the construction site through the lifting ring to lift the device. The telescopic member used is a hydraulic cylinder 2, which can achieve telescopic movement, and the clamping plate 3 can be driven to move by the telescopic movement of the hydraulic cylinder 2, so that the clamping plates 3 on both sides can be clamped on the support beam 7. Since the hydraulic telescopic mechanism can provide great power, and the clamping plates 3 are provided with protruding sharp teeth, the clamping plates 3 can easily crush the support beam 7, thereby realizing the crushing and removal of the support beam 7.

[0022] The dust reduction mechanism is used to reduce dust when crushing the support beam 7. The dust reduction mechanism includes a nozzle 5, which is installed on the bracket through a metal shaping tube 6. The nozzle 5 is connected to an external water supply system, thereby realizing spray dust reduction. Moreover, after using the metal shaping tube 6, it is convenient to adjust the spray position of the nozzle 5 according to needs, and the use is more flexible.

[0023] In actual operation, first use a cutting machine to cut a 20 cm incision in the support beam 7, then use a tower crane to lift the device and put it into the incision, and then the telescopic parts start to work, so that the clamps 3 on both sides can crush the middle support beam 7. After crushing one section, the tower crane moves the device one section and continues to crush the support beam 7, so that the support beam 7 can be finally crushed and removed.

[0024] This approach has the following benefits;

[0025] 1. Since the support beam 7 is removed by crushing, the removal operation can be carried out on the spot without the need for a transfer site, which is more convenient;

[0026] 2. The whole crushing process has low noise, does not disturb people, and can be constructed at night;

[0027] 3. The dust suppression mechanism can be used to suppress dust during the crushing process, so it is not easy to cause dust diffusion, dust generation, and is more environmentally friendly;

[0028] 4. The device has a simple structure, is easy to operate and has strong practicality.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
