Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a boom sinking installation device for a wet spraying machine. Background Art

[0002] Among the existing tunnel construction machinery, wet concrete spraying machine is a relatively common support equipment. When performing support spraying and mixing operations in tunnel construction, wet concrete spraying machine equipment is widely used because of its multi-angle, all-round, large-range and high-efficiency concrete spraying operation capabilities. However, due to the limited working space in tunnels or underground, in order to meet the transportation and walking of small and medium-sized tunnels underground, there are certain height restrictions on wet concrete spraying machines. At present, the boom installation form used by wet concrete spraying machines is mostly arranged on the platform surface of the frame, which makes the overall equipment too high. At the same time, the center of gravity is too high when in working state, which cannot meet the walking and transportation of small and medium-sized tunnels. When wet concrete spraying machines are walking in complex environments, the boom is prone to collisions, resulting in structural damage.

[0003] To this end, it is a technical problem that technical personnel in this field urgently need to develop a wet spraying machine boom sinking installation device that can not only lower the overall boom height and lower the center of gravity of the equipment when it is working, but also protect the boom structure in the frame to prevent the boom rotating part from bumping and causing damage to the rotating structure when the wet spraying machine is walking in a complex environment. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provides a wet spraying machine arm support sinking installation device.

[0005] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0006] The wet spraying machine arm sinking installation device comprises a frame, walking mechanisms (1) are respectively provided on both sides of the frame, a frame groove (2) is provided at the front end of the frame, a slewing mechanism (3) is provided in the frame groove (2), an arm mechanism is provided on the slewing mechanism (3), the arm mechanism comprises a supporting arm (4), a connecting arm (5) and an oil cylinder (6), the bottom of the supporting arm (4) is connected to the top surface of the slewing mechanism (3), the top of the supporting arm (4) is hinged to one end of the connecting arm (5), the bottom surface of the connecting arm (5) is hinged to one end of the oil cylinder (6), and the other end of the oil cylinder (6) is connected to the top surface of the slewing mechanism (3).

[0007] Preferably, the connecting arm (5) is a telescopic arm, and the top of the supporting arm (4) is hinged to the fixed end of the telescopic arm.

[0008] Preferably, a machine cover (7) is provided on the frame, and an arm support frame (8) is provided on the top surface of the machine cover (7).

[0009] Preferably, the slewing mechanism (3) is connected to the frame groove (2) via a bolt structure.

[0010] Preferably, a guard plate arranged around the slewing mechanism (3) is provided on the frame groove (2).

[0011] The utility model is further described below:

[0012] The utility model discloses a wet spraying machine arm support sinking installation device which is mainly composed of a frame, a frame groove, a slewing mechanism and an arm support mechanism.

[0013] The frame serves as the base frame of the wet spraying machine, and the walking mechanisms on both sides are used for the wet spraying machine to travel. The frame groove is located at the front end of the frame, providing a sunken installation platform for the arm mechanism. Due to the use of the sunken groove structure, the arm is sunken and installed in the frame groove, which can well reduce the overall arm height and also reduce the center of gravity of the equipment when working; the slewing mechanism at the bottom of the arm is installed in the frame groove designed by the frame through bolts, which can also prevent it from colliding and causing damage to the slewing mechanism. The slewing mechanism is surrounded by the frame steel plate in the middle, and the guard plate further provides a protective effect. The arm device includes a support arm, a connecting arm and a cylinder for lifting or lowering the connecting arm. The connecting arm can be a telescopic arm with telescopic function. The arm support frame is installed on the top of the wet spraying machine hood to fix and limit the connecting arm.

[0014] When the wet spraying machine is in the transport walking state, the walking mechanism is running, the slewing mechanism rotates the arm mechanism to the retracted position, and the telescopic arm is placed on the arm support frame, which can ensure the stability of the arm during the equipment transportation and limit the arm mechanism to ensure that it does not hit the machine cover; when it is in the spraying working state, the walking mechanism stops, and the slewing mechanism rotates the arm device to the extended position for work. Since the slewing mechanism is all inside the frame groove, it is ensured that there will be no slewing mechanism interference and other problems during rotation, and it also protects the operator from accidental contact with the arm slewing mechanism and mechanical damage.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The arm mechanism is sunk and installed in the groove of the frame, which reduces the height of the arm and moves the center of gravity downward, enhancing the transport and driving performance of the equipment in small and medium-sized lanes and ensuring the stability of the equipment during operation.

[0017] 2. By installing the arm mechanism downward, the height of the hood part can be effectively lowered, thereby achieving the purpose of lowering the overall equipment.

[0018] 3. The slewing mechanism is installed in the groove of the frame and is surrounded by guard plates to prevent the slewing mechanism from being damaged by collision.

[0019] In summary, the boom sinking installation device for wet spraying machine described in the utility model can well reduce the overall height of the boom and lower the center of gravity of the equipment when it is working; through the installation method of sinking layout, the slewing structure is protected in the frame to prevent the slewing part of the boom from bumping and causing damage to the slewing structure when the wet spraying machine is walking in a complex environment. Lowering the height of the boom can reduce the height of the hood required to be placed on the boom in the transport walking state, and finally meet the demand for lowering the overall height of the equipment, thereby meeting the walking and transportation of small and medium-sized lanes.
